As detailed at Thread:264489, to avoid overly long articles, highly-recurring character pages' biography should only have AT MOST 2-3 sentences per story, not whole paragraphs of plot detail. This page needs a major cleanup in that area.
- You may be looking for the Shadow World version of this incarnation.
Initially stern and ruthless, but actually kind and forgiving, the Twelfth Doctor was the first incarnation of the Doctor's second regeneration cycle, bestowed upon him by the Time Lords at Clara Oswald's urging at the end of the Siege of Trenzalore.
Assured of the survival of Gallifrey, the Doctor was no longer chained down by guilt, becoming a less amiable character, as he no longer needed to cover the pain of what he thought was the extinction of the Time Lords, with a withdrawn attitude who habitually questioned his own goodness. He often dispensed with niceties in a tense situation, becoming cold and calculative when needed. However, despite his ruthless exterior, the Doctor was actually deeply caring and empathetic, always striving to help others for the sake of being kind.
It was not until his first battle with Missy that the Doctor resolved his morality crisis, realising he was simply "an idiot with a box and screwdriver" who went around helping others. Following this, the Doctor began to show his lighter side more clearly and forged a closer bond with Clara. After her death, he spent four and a half billion years in his confession dial to reach Gallifrey due to Rassilon's concern with the Hybrid. Seeking revenge, the Doctor broke his own moral codes and unleashed his wrath upon the Time Lords in an ultimately futile attempt to save Clara, losing his memories of her as a price for his reckless actions.
After a final reunion with River Song, the Doctor was charged with guarding Missy in a vault at St Luke's University with Nardole. Sometime into this role, he began tutoring Bill Potts, who soon became his travelling companion, with Nardole joining them after an invasion by Monks. When testing Missy's rehabilitation resulted in Bill becoming a Cyberman, Missy leaving with the Master, and Nardole having to be left behind, the Doctor was mortally wounded in battle against the Cybermen.
Trying to halt the regenerative process after growing weary of constantly changing personas and losing companions, the Doctor crossed paths with his original incarnation and the Testimony, and was encouraged to regenerate by glass avatars of Bill and Nardole. Accepting his impending regeneration and his responsibility to life itself, the Doctor used his last moments to give his successor some words of advice, willingly accepting to carry on being the Doctor before finishing his regeneration into a female body.

A day to come
After sealing Gallifrey away in a pocket dimension, (TV: The Day of the Doctor) the Seventh Doctor was able to recall teaming up with his other twelve incarnations to save Gallifrey. (AUDIO: Cold Fusion)
When the Tenth Doctor met River Song, she told him about his future self giving her a sonic screwdriver (TV: Silence in the Library) and about her last meeting with "the future [him]" at Darillium. (TV: Forest of the Dead) Due to being on his last regeneration, (TV: The Time of the Doctor) the Eleventh Doctor believed River had been talking about him. (HOMEVID: Last Night)
When the Eleventh Doctor and River were invited to a party held by the fish people, River told the Doctor that, if the party went badly, she would "tell the next version of [him], [she had] told [him] so". (COMIC: An Adventure in Brine and Plaice)
During a visit to a parallel universe where he was a fictional character in a television series, the Eleventh Doctor told his portrayer, Matt Smith, that Peter Capaldi would be a good choice to play him on the show, as the Doctor had previously saved his universe's Peter Capaldi from a Mandrel. (COMIC: The Girl Who Loved Doctor Who)
After fighting in the Siege of Trenzalore for nine-hundred-years, (PROSE: Tales of Trenzalore) the Eleventh Doctor was granted a new regeneration cycle by the Time Lords after an appeal by Clara Oswald. After using the energy from the explosive reset that followed to destroy the Dalek forces, the Doctor returned to his TARDIS to complete his regeneration, (TV: The Time of the Doctor) making a quick phone call to Clara, during which he learned his next incarnation would be old and grey-haired. (TV: Deep Breath) Suddenly changing in a flash before Clara's eyes, the new Doctor voiced his surprise at having new kidneys as the TARDIS began a crash landing. (TV: The Time of the Doctor) Crashing in pre-historic Earth, the TARDIS was chased and subsequently swallowed by a female tyrannosaur; when the Doctor brought the TARDIS to 1890s London, the dinosaur was accidentally brought along with it.
After the TARDIS was spat out, the Doctor, in a severe bout of post-regenerative trauma, acted wild and irrationally, until he passed out in front of the Paternoster Gang. Though put to bed to stabilise, the Doctor soon awoke and, hearing the dinosaur in pain, climbed out onto the rooftop and left on horseback when he saw the T-Rex was being burned to ashes. Deciding to investigate, but still suffering a degree of post-regenerative stress, the Doctor wandered the streets of London. Talking to a passing tramp, the Doctor examined his new facial features, noticing that he had seen it before, before trading in his previous incarnation's favourite watch for the tramp's coat. (TV: Deep Breath)
Seeing an ad in a newspaper placed by Missy, (TV: Death in Heaven) which seemed to be a message from Clara, the Doctor infiltrated a suspicious restaurant, where he and Clara learned that time travelling Clockwork Droids, under the leadership of the Half-Face Man, had been harvesting humans to repair themselves and reach the Promised Land. Trying to speak on peaceful terms, the Doctor snapped the Control Node out of his illusion of the Promised Land by revealing the true state of his existence. Conflicted and unsure, the Half-Face Man fell out of his escape pod, either jumping or having been pushed by the Doctor.
Returning to his TARDIS, the Doctor briefly left Clara behind (TV: Deep Breath) due to the calculations he had been working on through all his prior incarnations finally being completed, and he went to help his previous twelve incarnations place Gallifrey in a pocket universe at the end of the Last Great Time War, (TV: The Day of the Doctor) joining the General in the War Room to coordinate disaster relief. With Gallifrey saved, the Twelfth Doctor went to a tea party in the Under Gallery to celebrate with his other incarnations. (PROSE: The Day of the Doctor) The Doctor then redecorated the TARDIS console room and settled on a new outfit, (TV: Deep Breath) creating his new control console in a bathroom. (COMIC: The Body Electric)
Returning for Clara, the Doctor spoke of the suspicious way Clara had met him in his previous incarnation, only for Clara to likewise voice her uncertainty of the Doctor's identity and asked to be returned home. Attempting to return Clara home, the Doctor ended up in Glasgow by mistake. However, Clara decided to go out for coffee with the Doctor after the Eleventh Doctor called her and encouraged her to help the Doctor through his regeneration. (TV: Deep Breath)
Wanting to investigate a series of murders, the Doctor went to get Clara some coffee from the Intergalactic Coffee Roasting Station, where he bumped into an old acquaintance, 78351, and witnessed the murder of a female customer. Deciding to take 78351 on as a companion, the Doctor examined the dead body and determined that all the caffeine in her system had been drained from two bite marks on her neck, just as a Blowfish was also murdered. Using his sonic screwdriver, the Doctor found that 78351's adrenaline levels had increased, and, fearful that he would be the next victim, took him to the master control centre to draw out the killer. Finding the technicians murdered, and that they had been killed fourteen hours before the first victim, the Doctor realised that 78351 was the killer.
Wanting to take him off the station, the Doctor had 78351 take him to his ship and they fled the ICRS. Turning out the ship's lights to see 78351's true form, the Doctor likened 78351's transformation to puberty, and told him he had to decide if he wanted to control his adult body. When he also told him that he might not have the energy to stabilise himself, 78351 set his ship to collide with a nearby sun to get the energy burst. Promising to buy 78351's friend a coffee from him, the Doctor left the ship in an escape pod, and returned to the ICRS. (PROSE: Lights Out)
Intending to return to Clara with some coffee, the Doctor saved a Combined Galactic Resistance fighter pilot named Journey Blue from a Dalek saucer attack (TV: Into the Dalek) in the Ryzak solar system, (PROSE: The Secret Lives of Monsters) though left her deceased brother behind in the explosion. After prompting her into asking nicely, the Doctor returned Journey to her command ship, the Aristotle, where Colonel Morgan Blue introduced him to a Dalek that had developed a fault and turned good. Returning for Clara, three weeks later from her perspective, the Doctor asked her if she thought he was a good man, a question that Clara found herself unable to answer, and returned to base to help the Dalek.
Joined by Journey and two other soldiers named Gretchen Carlisle and Ross, the Doctor and Clara used a moleculon nanoscaler to miniaturise themselves and enter the Dalek, whom the Doctor nicknamed "Rusty". After losing Ross to the Rusty's antibodies, the Doctor discovered a radiation leak from within Rusty and learned that he had turned good after seeing a star being born. Following the radiation, the Doctor discovered damage to Rusty's power source was slowly killing him, and repaired the damage with his sonic screwdriver. However, fixing Rusty's power core resulted in the malfunction that turned Rusty good to be reversed, with Rusty's destructive nature returning, and causing Rusty to go on a killing spree, as well as send a distress beacon to summon the Daleks to the rebels' base.
After getting slapped and lectured by Clara for his apathy, the Doctor realised he could turn Rusty good again by reawakening his memory of the star being born. Instructing Clara to find a way to restore Rusty's memories of the star, the Doctor made his way to the Kaled mutant within Rusty to mind link with him, causing Rusty to see the Doctor's hatred of the Daleks and destroy the Daleks that had responded to his distress beacon. Leaving to continue his crusade against the Daleks, Rusty commented that Doctor would have made a good Dalek before both of them left. After declining Journey's request to travel with him and Clara, the Doctor returned Clara home, both still unsure if the Doctor was a good man, but with Clara convinced he was at least trying to be one. (TV: Into the Dalek) The Doctor then thought about what kind of Dalek he would be. (PROSE: Dalek)
The Doctor joined a crew of six travellers, including a young Geoffrey Chaucer, on a journey to the church at Santiago de Compostela to avoid the plague. At the church, one of the travellers gave birth, and then the group was attacked by life-feeding aliens disguised as wooden skeletons. However, the aliens recoiled in horror upon seeing the new baby. The Doctor realised the church was actually the aliens' disguised spaceship, and he and the crew escaped as the ship took off. The Doctor explained to Chaucer that the baby, representing new life, was enough to frighten away the death-conquering aliens. (PROSE: The Mercy Seats)
New adventures with Clara
After he was forced to disguise himself as a nun to escape the Church of Vindication's Inquisitors, (COMIC: The Swords of Kali) the Doctor became alerted to a creature that disguised itself as a motorway to consume planets into other dimensions. Summoning Clara to assist him, the Doctor was surprised when the creature disappeared, unaware that Clara had tricked the creature into consuming itself. (COMIC: Road Rage)
The Doctor was given some chips by Clara, and then rambled about how great they tasted. (COMIC: Untitled) Attempting to get a reservation at a restaurant on Calbaron III, the Doctor and Clara found there was a three-year wait for a table. They booked and went three years to the future, only to learn the restaurant was closed to celebrate the third anniversary of the overthrowing of a tyrannical emperor. They finally made their booking six years prior for three years later. When the Doctor found that the tyrannical emperor had scratched his TARDIS, he decided to overthrow him, resulting in the anniversary. (COMIC: Planet of the Diners) The Doctor repaired the scratch on the TARDIS, but found that the damage had caused time within the TARDIS to temporarily run backwards, much to Clara's annoyance when she tried to converse with him. (COMIC: The Inversion of Time)
When the TARDIS was swarmed with Adipose, the Doctor claimed he was "not an Adipose person." He then had Clara take out the rubbish, as he claimed he wasn't a "taking-the-bin-out" person, with Clara declaring his attitude had to stop. (COMIC: The Bin Dilemma)
Deciding to return to Victorian London, the Doctor and Clara reunited with the Paternoster Gang to investigate a carnival at the Frost Fairs, where some performers had gained powers, in connection with a death that had occurred. They discovered these events were linked to weapon-creator Orestes Milton, who was hiding from the Shadow Proclamation. The Doctor stopped Milton's anger-inducing machine, but was unable to prevent his escape. However, Affinity, a shape-shifter created by Milton, tricked him into thinking the Shadow Proclamation wanted his help, and the real Shadow Proclamation destroyed Milton's ship when it attempted to leave Earth. The humans altered by Milton retained their powers, and decided to resume their work at the fair. (PROSE: Silhouette)
Deciding to give Clara the choice of their next destination, the Doctor took her to Sherwood Forest to meet Robin Hood, though he was sceptical of Robin's actual existence. He was proven wrong when Robin shot his TARDIS with an arrow seconds after they arrived; however, he refused to believe Robin and his Merry Men were real upon visiting their camp. After participating in an archery contest for a golden arrow, the Doctor got himself, Clara and Robin captured by the Sheriff of Nottingham, who had allied with alien robots disguised as his knights.
Escaping, the Doctor and Robin found out the robots were trying to reach the Promised Land, but lacked sufficient gold to repair their engine. Believing Robin was also a robot, the Doctor was re-captured by the Sheriff as Robin took Clara and escaped through a window. Leading a revolution in the Sheriff's dungeon, the Doctor was informed by the Sheriff that Robin Hood was not a robot, just as Robin came to his rescue and defeated the Sheriff. Assisting Robin with Clara's help, the Doctor helped launch the golden arrow into the ship to allow it to escape velocity and explode harmlessly in space. As he departed, the Doctor left Maid Marian, whom he had met in the Sheriff's dungeon, behind to be reunited with Robin. (TV: Robot of Sherwood)
The Doctor and Clara used a goo bomb to foil the Sibro's attempt to weaponise a Conlanian clock tower, (COMIC: Chime Time) orchestrated a ceasefire in a war between anthropomorphic cats and dogs by allying them against an army of alien fleas that planned to attack every planet in the universe, (COMIC: Once Bitten) and helped the World Brain find a new way of life after crash landing on its factory planet. (COMIC: Crash Landing)
On Hoopoe, the Doctor acted as Clara's lawyer when she was arrested for walking on the ground by the Court of Birds. His attempt to convince them she and him weren't cats backfired when the owls accused them of being mice, but the Doctor had foreseen this and had recruited the native cats to attack the owls with makeshift wings, but ensured that the wings were too difficult to use properly, rendering them useless in the cats' pursuit of the owls. As he left with Clara in the TARDIS, the Doctor rewarded the cats with a box of canned tuna. (COMIC: The Court of Birds)
Becoming obsessed with the idea that a creature designed to hide was following him around, and that everyone was similarly being followed, the Doctor began searching for such a creature. (TV: Listen) In his pursuit, the Doctor encountered an individual who also feared such an entity, and told them that the fear they felt was something he had lived with all his life while travelling in his TARDIS. (WC: Listen) Still unable to find the creature, the Doctor recruited Clara's help in finding the creature by using the TARDIS telepathic circuits to find it in her past. However, Clara got distracted by a phone call from Danny Pink, and piloted them into his past instead, back when Danny was a child called "Rupert" and living in a care home. Finding a figure under Rupert's bed sheet, the Doctor had Clara and Rupert turn their backs to allow the being to walk out the room unobserved, leaving them unsure if it really was the creature or just another child playing a trick on Rupert.
Returning Clara to her date, the Doctor continued to follow his theory by trying to use a trace of Clara left in the telepathic circuits, ending up at the end of the universe where a time traveller named Colonel Orson Pink had been trapped for six months. Intrigued by how following Clara's timeline led him to Orson, the Doctor returned for Clara and had them wait at the end of the universe for the night, believing it to be the perfect time to find out if the creatures were real. Finding a chance to confront the creature outside the ship, the Doctor sent Clara into the TARDIS and seemed to get a look at what he'd been chasing before the atmospheric shell broke and Orson had to rescue him. As the Doctor was knocked out, and the TARDIS seemed to be under attack, Clara used the telepathic circuits to fly the TARDIS away. The Doctor woke up to find Clara gone, but, before he could investigate, Clara re-entered the TARDIS and made him promise to leave and not find out where they had landed. Afterwards, the Doctor returned Orson and Clara to their own times and, satisfied by what he had learned, underlined the "LISTEN" that had been written on his chalkboard. (TV: Listen)
The Doctor planned to rendezvous with Clara at Coal Hill School, but instead arrived at a replica of the school on an unnamed planet, where Clara and Jeff Delobel, a French teacher, had been abducted by primitive aliens planning to infiltrate Earth via Coal Hill School. In order to thwart the invasion, the Doctor told the aliens a tale of Earth's Guardian, informing them that he was the guardian, scaring the aliens off. (COMIC: The Monsters of Coal Hill School)
Returning to pick up Clara, and persuade her to away from a date with Danny in favour of other travel destinations, the Doctor received a call from Madame Karabraxos, who requested he free the Teller and its mate from the Bank of Karabraxos, as he had done on the day she met him. Realising the ramifications of this request, the Doctor built up the identity of "the Architect", using this identity to stage a bank heist for him to commit, with the assistance of Clara, an augmented human named Psi, and a shape shifting mutant human named Saibra. Using memory worms to erase the plan from their minds and prevent the Teller from alerting the young Karabraxos, the Doctor and Clara found themselves already in the Bank with their accomplices, their last memory being the TARDIS phone ringing.
Receiving instructions from the Architect on their location, objective, and the Bank's security system, the team infiltrated the Bank. Entering a safety deposit box, the team set of a dimensional shift bomb into a service corridor, where the team found a briefcase containing six teleporters disguised as atomic shredders. Seemingly losing Saibra and Psi to the shredders when the Teller locked onto them, the Doctor figured out that time travel was involved with the heist plan when a perfectly-timed solar storm unlocked the Bank's vault. Retrieving what the Architect had promised Psi and Saibra as payment, the Doctor and Clara were caught by the Teller and delivered to the bank manager, Ms. Delphox. After Delphox left them to be executed, the Doctor and Clara were saved by Psi and Saibra, who revealed the true nature of the "shredders".
Venturing into the Bank's private vault to find his and Clara's reward, the Doctor instead found Director Karabraxos, and discovered that Delphox, as well as a majority of the bank's staff, was an exact clone of Karabraxos. Seeing Karabraxos' hatred of her own clones caused the Doctor to have an epiphany on the identity of the Architect, and he gave his phone number to Karabraxos as she fled from the solar storm about to hit the Bank. Subjecting himself to the Teller's powers, the Doctor regained his lost memories and realised the true objective of the bank heist. Freeing the Teller and its mate to a place to live in solitude, the Doctor then parted ways with Psi and Saibra, giving them their rewards, and returned Clara home for her date. (TV: Time Heist)
The Doctor and Clara were left to the mercy of sand piranhas while chained to posts on a desert planet, (TV: The Caretaker) helped stranded Seevith launch their ship, (COMIC: More Than Meets the Eye) and helped Professor Faster end the 17th century witch trials. (COMIC: Witch Work)
The Doctor and Clara rendezvoused with fish people, (TV: The Caretaker) were saved from being "turned into toast by an Aaraanandal slime beast" by Simon, (PROSE: When the Wolves Came) had a dinner date in 1937 Berlin, (TV: Kill the Moon) outran soldiers to escape in the TARDIS, (TV: The Caretaker) and saved a small village from a Cephla at Christmas. (COMIC: Gift Snatched!)
Planning to visit Eden 2, the Doctor was joined by a reluctant Clara, after she phoned him to drop her off at work after she overslept. When the duo arrived, they found the planet under assimilation by the Vladlack, but it turned out that the planet was a trap to lure in and arrest invaders of planets. Fearing that innocents could be inappropriately punished, the Doctor set up a warning beacon around the planet, then dropped Clara off at Coal Hill School. (COMIC: Freeze)
Meeting Danny and Courtney
During one of his visits to Clara, the Doctor discovered a Skovox Blitzer near Coal Hill School, and went in "deep cover" as the school's temporary caretaker to dispatch of the killer robot. To keep Clara from interfering, the Doctor revealed his plan was to use chronodyne generators to send the Blitzer thousands of years into the future.
However, the Doctor's plan was accidentally foiled by Danny Pink; Danny had seen the Doctor act suspiciously and believed the devices were of malicious intent, deactivating some. As a result, the Blitzer was sent a short time into the future, rather than centuries. After Clara introduced Danny as her boyfriend, the Doctor took a dislike to him as he was a former soldier and feared he wasn't good enough for Clara. He changed his plan to using a communication device to make the Blitzer think the Doctor was its superior.
When the Blitzer returned during the next evening, Danny used his military training to help keep the Blitzer occupied, allowing the Doctor to repair the malfunctioning device. After successfully commanding the Blitzer to deactivate, the Doctor took it into space and ejected it from the TARDIS, taking Clara's troublesome pupil Courtney Woods with him after she discovered his identity, deciding that there was no harm in having Courtney tag along as a travelling companion, (TV: The Caretaker) but didn't see anything special in her. (TV: Kill the Moon)
Further adventures with Clara
Discovering that a group of aliens were going to turn a planet of anthropomorphic pink hippopotami into stone, the Doctor intercepted the aliens at the early stages of their invasion and led them to ancient Egypt, where they petrified a large cat-like alien, creating the Sphinx and getting crushed in the process. He and Clara then returned to the planet of the anthropomorphic pink hippopotamuses to reverse the petrified effect. (COMIC: Petrified)
The Doctor and Clara turned Captain Ratlett's crew against him and showed them a better life, (COMIC: The Wheelers) were almost consumed by robotic bananas for stealing food from the moon Luna Schlosser, (COMIC: Five a Day) and saved the Cloud City of Mirmi 24 from being eaten by an alien snake. (COMIC: The Very Hungry Snake)
While attempting to hang flowers on the exterior of the TARDIS, the Doctor was spooked by a future Clara and fell out of the TARDIS into the orbit of an asteroid. When Clara's attempt to avert the crisis ended up causing it, the TARDIS was able to save the Doctor by creating a time field around him. (PROSE: A Long Way Down)
Heading for Rome, the Doctor and Clara wound up in a German forest, where they were apprehended and taken into a nearby encampment, where they learnt that robotic mosquitoes were spreading disease and killing off the soldiers. Tracking the energy fields of the mosquitoes to a tower in the woods, the Doctor discovered the occupants were using the mosquitoes to search for a cure to a plague infecting their own world. The Doctor convinced them to leave. (PROSE: Silver Mosquitoes)
Fallout with Clara
At Clara's urging, the Doctor took her and Courtney to the Moon in 2049, so that Courtney could be the first girl on the Moon to bolster her confidence. Landing instead in a recycled space shuttle heading for the moon, the Doctor was informed by Captain Lundvik that the moon had inexplicably gained mass, and that she and her crew were going to use nuclear bombs to dispose of the additional mass. Investigating a disused mining base from a previous mission, the Doctor, his companions and the astronauts found corpses preserved in webs and research that suggested that the moon was disintegrating. Soon after, the group was attacked by a spider creature, which Courtney killed with washing up equipment, but not before Lundvik's whole crew was killed.
Taking a scared Courtney back to the TARDIS, the Doctor voiced his uncertainty of the Moon's fate to Clara, calling it a "grey area" in time. Exploring the moon's surface for the reason behind the deterioration, the Doctor, Clara and Lundvik discovered a horde of spider germs beneath the Moon's surface, as well as amniotic fluid, prompting the Doctor to investigate beneath the Moon for answers. Scanning the Moon's core, the Doctor discovered that the Moon was, in fact, an egg for an ancient creature that was hatching. Reuniting with Clara and Lundvik after the shuttle and the TARDIS fell into a canyon, the Doctor informed them of his discovery after establishing contact with Courtney's phone. While Clara and Lundvik argued about killing the creature for the sake of the Earth, the Doctor had Courtney bring the TARDIS to him via a DVD, deciding that it was not his place to decide the Moon's future, and left in his TARDIS for Clara, Lundvik and Courtney to decide on behalf of humankind.
After Clara chose to spare the creature, despite humanity voting for its death, the Doctor returned for the three women, taking them to a beach on Earth to see the creature hatch and the Moon harmlessly disintegrate in Earth's atmosphere. Confirming that the sight of the moon hatching kick started the humans pioneering into space, and seeing the creature hatch a new egg with same mass as the old Moon, the Doctor returned Courtney and Clara to Coal Hill School. However, Clara, angered by the position the Doctor had put her in, asked the Doctor if he had known the egg was harmless, which the Doctor confirmed as true. Tired of the Doctor's apathy, Clara argued with the Doctor about how he had almost caused her to kill an unborn creature, and, deeply hurt by the Doctor's constantly patronising attitude toward humanity in general, she told him to leave and not return for her. The Doctor was left stunned by her reaction and immediately took off. (TV: Kill the Moon)
Time away from Clara
Responding to a distress call from a Dalek prisoner aboard a Cyber-ship, the Doctor discovered that the Daleks, Cybermen and Sontarans were searching for the Orb of Fates to gain control of a powerful Time Lord weapon called the Starbane. The Doctor joined forces with the Dalek prisoner, who had been altered by the Cybermen and had "seen the light", and nicknamed it "Lumpy". Following the Orbs' artron energy to the Cyber-tombs of Telos, the Doctor restored a minimum of Lumpy's power, not trusting the Dalek to allow full use of its power, and sent him to retrieve the second Orb while he studied the first in the TARDIS.
As Lumpy descended into the depths of Telos, the Doctor discovered that the Orbs were powered by temporal energy, and the only way to destroy them was to create a temporal implosion. Leaving Telos for Sontar, the Doctor and Lumpy were trapped in a stasis field by Major Skar, but the Doctor was able to open the field and allow Lumpy to escape undetected while he stayed behind as a diversion. After Lumpy acquired the last Orb and deactivated the stasis field, the Doctor escaped with Lumpy. They next travelled to the Starbane, which was already occupied by Daleks. When the Doctor learned that Lumpy had not turned to good, he found a way to access Lumpy's controls remotely and used this ability to destroy the Starbane, while he piloted the TARDIS away. (GAME: The Doctor and the Dalek)
When Clara decided she and the Doctor should have "one last hurrah" before parting ways for good, the Doctor took her to the space-bound Orient Express, choosing the destination with an inkling that something exciting would happen after having been lured with phone calls, mysterious summons and free train tickets in the past. After discovering the death of an elderly passenger, and urging himself to investigate, the Doctor went to the engine room to examine the dead passenger's Excelsior Life Extender, meeting Chief Engineer Perkins in the process, and learned the legend of the Foretold. Seeking advice from Emile Moorhouse, a fellow passenger who was a Professor of Alien Mythology, the Doctor soon discovered a second death had occurred in the kitchen.
Confronting Captain Hector Quell with his theory, but getting ignored, the Doctor joined Perkins and Moorhouse in the engine room to research the deaths. Calling Clara to update her, the Doctor discovered that she and Maisie Pitt were trapped in a storage cart with a sarcophagus. Fearing that Clara was trapped with the Foretold, the Doctor tried to rewire the door open, only to find the sarcophagus empty, and himself under arrest by Quell for being a stowaway. However, after witnessing a third death first hand, Quell realised that the Doctor was right and allied with him, just as the Doctor deduced the true nature of the Orient Express; the passengers were all experts and scientists in specific fields of study, gathered there to study the Foretold. With a lab revealed and the hologram passengers disappearing, the train's computer, Gus, gave the scientists the necessary instructions and equipment. Losing Moorhouse to the Foretold, the Doctor and Perkins figured out that the Foretold was targeting the weaker passengers after looking at the medical history of the previous victims, just as Quell was killed by the creature, as he had post-traumatic stress, but not before he gave the Doctor the necessary description to defeat the Foretold.
Realising that Maisie was next due to her breakdowns, the Doctor told a reluctant Clara to bring Maisie to the lab, where the Foretold appeared to Maisie, but the Doctor saved her by implanting a replica of her grief into his head, confusing the Foretold into thinking the Doctor was Maisie. Deducing that the Foretold was an ancient soldier augmented with technology, the Doctor surrendered, and, after a final salute, the ancient soldier crumpled to dust, with only the technology that kept him alive remaining. With the objective completed, Gus released the air out of the cabin, but the Doctor beamed all the dying passengers into the TARDIS, and tried to hack Gus to find out who had created him, but this trigged a security measure, causing the train to self-destruct. Dropping everyone but Clara and Perkins off at the nearest civilised planet, the Doctor waited for Clara to awaken on a beach before explaining everything.
Back in the TARDIS, the Doctor invited Perkins to travel with him, but Perkins politely declined and he and the Doctor bade each other goodbye. Reflecting on a conversation she had with Maisie, Clara, having forgiven the Doctor, decided to continue travelling with him, telling the Doctor that her leaving was all Danny's idea. (TV: Mummy on the Orient Express)
Resumed travels with Clara
Picking up a signal, the TARDIS arrived on the Quartz Wastes of Asmoray. Although the Doctor believed it was an uninhabited wasteland, Clara pointed out there was a harvester nearby extracting electricity from the quartz. The Doctor and Clara were brought aboard the harvester by two workers, where beings within the electricity had broken through and killed four workers. Their leader, Luther, was insistent on continuing their work regardless. Investigating, the Doctor and Clara found the creatures were only attacking because they were being sucked into the harvester's storage batteries. With Clara's help, the Doctor was able to free the electricity beings back into the quartz. (COMIC: The Body Electric)
Taking Clara to the Taj Mahal in India for a holiday, the Doctor was chosen to act as a hostage by Stellar Nexus while Nexus tried to get payment for Earth's supposed tax bills. When the Doctor challenged Nexus's claim by pointing out the illogic in his statement, and then insulted him by asking why he had never heard of Nexus's Empire, the Doctor was locked in a cell while an illusion of him was set against a dragon in a gladiator battle. When Clara managed to pilot the TARDIS into the Doctor's cell, the Doctor used his sonic screwdriver to deactivate Nexus's illusions, exposing that Stellar Nexus was a child-sized con artist whose entire Empire was an illusion. Sending the defeated Nexus away, the Doctor decided to treat Clara to a curry. (COMIC: Empire's Fall)
The Doctor took Clara to see the Lights of Tanzarr, but instead found that the Nameless Mist had entered N-Space and was threatening to devour the cosmos. Originally wanting to flee, the Doctor was convinced by Clara to save the inhabitants of Ferrous-Ferra, and was inspired to recruit Cold Steel to headline the "loudest rock show in history of sound". While Clara triangulated the transmissions to cover the local galaxy, the Doctor used the loud music to thwart off the Nameless Mist. With the day saved, the Doctor returned to the concert to celebrate with crowd surfing. (COMIC: The Big Hush)
Trying to return Clara home, the Doctor instead landed in Bristol when the Boneless began draining power from the TARDIS, drawing it off course and causing the exterior to shrink. Sending Clara to find the cause, the Doctor re-entered the TARDIS to study the shrinking effect, only for the TARDIS to shrink further, trapping him inside. Equipping Clara with his psychic paper and sonic screwdriver, the Doctor used nanotechnology to hack into Clara's optic nerve and establish a visual contact with the outer world. After Clara recruited the aid of a local named Rigsy, pretending to be the Doctor while doing so, the duo discovered that creatures from a two-dimensional universe were killing and dissecting missing locals to understand their three-dimensional bodies.
After discovering that Clara had lied to him about Danny's approval, the Doctor realised that a mural dedicated to local missing people was the missing people, killed and worn by the creatures as camouflage. With Clara leading a gang of surviving community servers, the Doctor theorised that the creatures were trying to communicate, and that the deaths were but a mere misunderstanding. When the theory was proved wrong, the Doctor invented a device that could reverse the creatures' flattening abilities, which he called a 2Dis, as Clara and her gang retreated to an underground tunnel.
After Clara accidentally dropped the TARDIS onto a train line, the Doctor activated the TARDIS' siege mode to protect it from an oncoming train. Now unable to even open the doors, which had been removed by the activation of siege mode, and with the life support systems failing as the power drain continued, the Doctor congratulated Clara for being worthy of the title "Doctor", unsure if she could hear him or even if she was still alive. Clara and Rigsy were able to trick the creatures into supplying the TARDIS with the necessary power to restore it to full working conditions. Naming his adversaries "the Boneless", the Doctor banished them back to their home universe. (TV: Flatline)
The Doctor landed on the Pollyanna, the first of the Ninth Era sunships, which had been on an expedition to circumnavigate the Sun. Seeing one of the Umbra come out of the Sun and enter a plasma intake, the Doctor rushed to the plasma lab and carried the injured Professor Alice Dubrovnik to safety. The Umbra, who had been trapped in the chromosphere for millions of years, began swarming the Pollyanna, anchoring the ship to the Sun to try and hijack it and use it as a way of reaching Earth. As the Umbra on board took on more humans as vehicles, the Doctor was ejected out of a plasma intake to attract the Umbra to his regret. He set up the final link to Alice's graviton inverter on the hull of the ship, allowing Alice to briefly boost the inverter and create a secondary gravity envelope, which inverted the gravity and the heat, freezing the Umbra on the ship to death. (COMIC: The Eye of Torment)
The Doctor brought Clara to the planet Isen VI to check on a faint warning signal of Gallifreian origin. They found the planet being terraformed by Kano Dollar and his company, Dollar Intergalactic, which woke up a Hyperion named Rann-Korr, who was hiding in hibernation since the alliance of races led by Rassilon defeated Hyperios. The Doctor managed to freeze Rann-Korr by reversing the terraforming process while using himself as a bait. (COMIC: Terrorformer)
The Doctor tried taking Clara to the 1641 frost fair, but was instead drawn off course and landed in the Sahara Desert in 1941, where they were captured by Nazis. While negotiating with Field Marshall Erwin Rommel, the Doctor learnt that the Tuareg tribesmen had made allies of "men from the stars", which he learned were the Sontarans, under the command of Commander Kygon Brox. Brox, believing the Doctor was looking for the Warsong, tried interrogating the Doctor with a mind scythe, but the Doctor instead used the link to gather information of the weapon, such as how the Warsong was taken to Earth, and that the Sontarans were seeking the weapon after signals from it began increasing exponentially.
After Nazi officer Heinz Bruckner was exposed as a Rutan spy, the Doctor witnessed the Warsong being triggered, just as he realised that Bruckner had taken Clara with him to the Warsong's activation. While having the Allied, Axis and Sontaran forces distract Bruckner by converging towards the Warsong, the Doctor and Rommel broke through its defences. Rommel threw Bruckner into the Warsong, killing him, while the Doctor destroyed the "orchestra" of the Warsong by using his sonic screwdriver to blow it up. Afterwards, he brought Clara to the frost fair. (COMIC: The Instruments of War)
Answering a summons from Tiger Maratha to 2315 India, the Doctor and Clara found that he had been drained of life, and were told by his daughter, Priyanka, that Tiger had worked for a group known as the Family Scindia. While searching the Scindia's ancestral home to find information, the Doctor stumbled through a dimensional door into 1825 India, where he was attacked by a demon, but rescued by renegade Amazon Rani Jhulka. The Doctor and Rani found a necro-cloud harvesting the spirits of the dead, and then were attacked by more of the demons. Before they could be overpowered by the demons, the TARDIS arrived due to Priyanka having unintentionally activated the telepathic circuits, and the Doctor was informed of Clara being taken by the demons.
Returning to 2315, the Doctor, Priyanka and Rani found a final recorded message from Tiger made before his death, in which he explained he had collected three of the four mythic swords of the goddess Kali for the Family Scindia and had a premonition of evil over the swords. The Doctor was then summoned to see the patriarch of the Scindia family, Chandra Scindia, and deduced that they were beings known as the Kaliratha, putting themselves throughout time and space and Hindu mythology. Chandra revealed he had Clara hostage, forcing the Doctor to agree to find the fourth sword of Kali for them. The Doctor, Priyanka and Rani collected the fourth sword and returned to Chandra, who revealed he had used Clara as a host for the resurrection of Kali. As the Doctor battled with Kali, he revealed he had hid his sonic screwdriver in the fourth sword, so that Kali unwittingly freed the evil spirits from her and released Clara's body, while Rani killed Chandra. The Doctor, Clara, Rani and Priyanka then attended a festival in Mumbai. (COMIC: The Swords of Kali)
After Clara accidentally freed the Djinx from his imprisonment, the Doctor was trapped in his TARDIS by the vengeful entity. Sending Clara instructions on her phone, the Doctor was able to instruct Clara on how to defeat the Djinx and free himself. (COMIC: Doctor in a Bottle) The Doctor and Clara then foiled a plot by Zorgo the Terrible, (COMIC: Zorgo the Terrible) and met Diana Winter. (AUDIO: The Gods of Winter)
After stopping a hostile invasion in the future, the Doctor travelled to UNIT HQ, where he shut down a Void portal. The Doctor came into conflict with the Fractures, natives of the Void that possessed humans, who believed they had to drag anyone marked with Void stuff into the Void to protect reality from unravelling. The chaos was started by a UNIT scientist from an alternate Earth, Paul Foster, who wished to be with a version of his family. Recruiting UNIT, Kate Stewart and the Fosters' help, the Doctor and Clara opened the Void, drawing the Fractures back inside and freeing their victims. At Clara's insistence, the Doctor allowed the alternate Paul to join his family in N-Space, knowing the Fractures were entirely out for him now. (COMIC: The Fractures)
After visiting an uninhabited world, Clara asked the Doctor about Marinus, but he did not remember the planet. That night, as he slept, the Doctor worked out that Clara was up to something, and woke up to find Clara missing and the TARDIS in 1923 Paris. Looking for Clara in a café, the Doctor ran into his two previous incarnations, who were also heading to meet their respective companions.
When the three Doctors barged into the café to confront each other, Clara, Alice Obiefune and Gabby Gonzalez explained that an alternative Gabby from a bad future had warned them of the plan devised by a future "alternate" version of the Twelfth Doctor, which involved using a continuity bomb to make his timeline concrete, and had then planned to rise the Voord on Marinus to be a new race of Time Lords and to conquer the universe. Realising that the picture still existed of the three Doctors arguing, they decided that going to Marinus was still part of the new timeline, and the three left Paris calmly, avoiding the Blinovitch Limitation Effect that summoned the Reapers and destroyed the café.
On Marinus, the Doctors posed for the picture and purposefully fell into the continuity bomb, entering the Eleventh Doctor's alternate timeline and used the TARDIS to go to the Voord's pocket universe. Met with Voord soldiers, the Twelfth Doctor pretended to be his alternate self to gain authority, but a Voord soldier, believing the deception, connected the Twelfth Doctor to the Voord's group mind, where he encountered his alternate self, and the two fought within the mindscape. Realising that his alternate self was too powerful to take on alone, the Doctor brought his other selves and their companions into the hive mind. Inside the group mind, the Tenth Doctor turned off the city's force field, threatening to wipe them out with acid lest he change the timeline, and the Eleventh Doctor reprogrammed the dimensional controls to return the Voord to the main universe. Convinced by Clara, the alternate Twelfth Doctor agreed and let history take its normal course, regressing the Voord and Marinus back to their primitive evolution.
Seeing the new Marinus, populated by large cities and primitive Voord, the six returned to Paris, and considered eating at the café, until they saw the Ninth Doctor and Rose Tyler seated inside, with the Twelfth Doctor saying that the Ninth Doctor had been left out of the plot due to there being no timeline that even the continuity bomb could find where he was anything but "fantastic". As the groups departed, the Twelfth Doctor noted to Clara that she and himself would slowly forget the event as well, as they had both learned about their own futures. (COMIC: Four Doctors)
Following Clara's request to meet the Greek storyteller Homer, the Doctor found himself drugged by an innkeeper and bound to a post with Homer and Clara to be fed to a bunch of Cyclopes. Before he could be eaten, however, the Doctor managed to convince the Cyclopes to listen to Homer's harp, and the young man's music soothed the hungry Cyclopes to sleep. Using a sub-conscience reading reality device, the Doctor discovered that the beasts were refugees from a war that had destroyed their world and, after using his device to convert them to a vegetarian diet, the Doctor let Clara convince them to live in peace in the hills. (COMIC: Doctor on the Menu)
The Doctor and Clara travelled to a galactic auction in Earth's orbit, where unclaimed storage was being bid on, with the storage pod belonging to Hyphen T Hyphen, a reclusive collector, containing a mother Rigellan Hyper-Kraken, which began killing everyone when the pod was opened. Before the mother Hyper-Kraken's eggs could hatch, the Doctor widened the dimensional shunt's focus on the Hyper-Kraken, her eggs and the storage pods and safely transported them elsewhere. (COMIC: Space Invaders!)
The Doctor and Clara travelled to the Sands Hotel in 1964 Las Vegas after the Doctor found some tickets to see Frankie Seneca in a drawer. After proving to be a good gambler, he caught the attention of Johnny Dragotta, who accused him of cheating. However, they were distracted when Mikey Nero, who was thought to have been killed, arrived, demanding control of the hotel. The Doctor unmasked Mikey as a disguised agent of the Cybock Imperium, who began attacking the hotel. While trying to immobilise it, the Doctor was grabbed and throttled by the Imperium, but was saved by Sonny Lawson.
The Doctor and Sonny discovered the Imperium's ships, and rescued Clara from their captivity. Clara gave the Doctor a Time Gun of Rassilon, which had been in the alien's possession. As the Imperiums attacked the hotel, the Doctor intervened and offered the aliens a game of Russian roulette with the gun. Although they agreed, the Doctor knew the gun would not work on a Time Lord, and it would also self-destruct if one attempted to use it on a Time Lord. When the aliens' leader, Kronos, attempted to shoot the Doctor with the gun, it accordingly wiped away his timeline, and the other Cybocks with him. The Doctor, Clara and Sonny then went to see Seneca perform. (COMIC: Gangland)
The Doctor and Clara visited the liberation of Paris in 1944, where they thwarted a plan by the Darapok Empire to brainwash humanity into destroying itself by destroying their transmitter on the Eiffel Tower, and then frightening them off. (COMIC: Trust)
The Doctor landed in London, only to find it and the rest of the world overrun by trees after Maebh Arden, a student of Coal Hill Year 8 Gifted and Talented Group under Clara and Danny's care, found the TARDIS. With his theories constantly being proven wrong, the Doctor came to the conclusion that the trees' sudden overgrowth was an act of aggression, while also dealing with Clara's students in his TARDIS after Clara and Danny arrived to collect Maebh, only for Maebh to slip away in the commotion, just as the Doctor noticed her homework had predicted the events of that day. Following Maebh deeper into the forest, the Doctor discovered that a sentience identifying itself as "the life that prevail[ed]" had caused the overgrowth, in preparation for a devastating solar flare about to hit the Earth. Believing Earth doomed, Clara inquired him to use the TARDIS as a lifeboat, only to inform him that she had said that to get him back to his TARDIS so he could survive the catastrophe alone. Despite some reluctance, Clara eventually convinced him to leave.
Immediately afterwards, having discovered upon further reflection that the trees were going to absorb the harmful solar flares by pumping the atmosphere with excess oxygen, the Doctor returned to Clara and explained his discovery to the Gifted and Talented Group. When he was informed of a government operation aiming to destroy the trees, the Doctor opened every mobile network on the planet to allow Maebh the opportunity to deliver a speech written by the Gifted and Talented Group to leave the trees alone. With Danny taking the children to their homes, the Doctor and Clara watched the trees that had grown around the world harvesting and extinguishing the solar fire in the TARDIS, and then returned to watch the trees disappear on Clara's balcony. (TV: In the Forest of the Night)
The Doctor attempted to take Clara to Blackpool, but they ended up arriving in 2089, by which point the pleasure beach had become an overgrown jungle. The Doctor befriended a wounded donkey he named Meghan, Who had been shot by a man called Triss, who was planning a hunting trip in hover pods powered by Blackpool Tower. The Doctor shut down the power, ending Triss' hunting plans. The Doctor and Clara had a dance in the Blackpool Tower ballroom, and then he enjoyed a play in the water with Meghan. (PROSE: All the Empty Towers)
While taking a helicopter ride for a tour of Snowcap University in 2048 Antarctica, the Doctor and Clara learnt that one of the students, Polly Evans, had stayed behind at the end of term to join the classified Project Sub-Zero. When another student, Quinn Norton, who also a part of Project Sub-Zero, was killed in a helicopter crash the Doctor and Clara narrowly avoided being on along with Polly's father George, they returned to Snowcap U to investigate. With the help of the spy Paul South, the Doctor found an ice cavern where the missing students had been experimented on, engineered by Dr. Patricia Audley to survive in extreme cold. To their shock, the Doctor and Clara also met Winnie Clarence, one of Clara's splinters, who refused to accept her only purpose was to die saving the Doctor. Paul and Winnie released most of the imprisoned humans from captivity.
Using his sonic screwdriver, the Doctor transmitted a signal that caused Dr. Audley's animals to go wild. After feigning betrayal of the two, Winnie threw the Doctor the key to free the hybrid subjects from their cells, and saved the Doctor's life by pulling Dr. Audley into a vat of liquid ice after Audley pulled a gun on him. Dr. Audley was killed, but Winnie survived when she unwittingly had a syringe of Dr. Audley's experimental blue blood serum injected into her, allowing her to live inside the ice. Clara realised that this meant that not all of the splinters died saving the Doctor, and several of them had lives of their own. (COMIC: Blood and Ice)
The darkest hour
After Clara suggested going to a volcano when the Doctor collected her from her flat, she attempted to put a mood patch on his neck, but the Doctor realised what she was doing and turned it on her. Not realising she was the one drugged, Clara imagined being at the volcano and throwing all the Doctor's TARDIS keys into lava, to blackmail him to save Danny, who had been killed in a road accident. The Doctor refused, and Clara came out of her dream state after destroying all the TARDIS keys. (TV: Dark Water) Due to lingering memories of becoming a recluse after a betrayal from Clara, (COMIC: Four Doctors) the Doctor forgave Clara, and they duo went to find a way for her to see Danny again. Arriving at 3W due to the telepathic circuits, the Doctor and Clara were greeted by Missy, who identified herself as a greeting droid and summoned Dr. Chang, who showed them the use of dark water in the mausoleum. Clara received a call from Danny, who was in the Nethersphere, and the Doctor and Chang left her to take it.
The Doctor and Chang discovered that the water tanks that held the bodies were being drained by Missy, who killed Chang and revealed that all the tanks held Cybermen, who were preparing to invade Earth. Escaping the building, which he discovered was St Paul's Cathedral, the Doctor tried to warn away nearby people, but Missy called out his warnings as insanity, and told him it was too late. The Doctor asked for her identity, and Missy revealed she was the Master, (TV: Dark Water) before she and the Doctor were apprehended by UNIT and brought aboard the plane Boat One, where the Doctor was made President of Earth to battle the Cybermen. Missy overpowered UNIT, killed Osgood, and attempted to kill the Doctor by blowing up the plane, but the Doctor survived his fall to Earth by skydiving into the TARDIS.
He travelled to a cemetery and reunited with Clara, who was comforting a converted Danny. Missy arrived and, as a "birthday present", gave the Doctor control of all the Cybermen. Missy planned to turn the Doctor into the leader of the new army, intending to prove that the two of them were not that different after all, believing that she had put him in the impossible position of either accepting control of the army and using it to "save" the universe or letting humanity die and conquer the universe as the Cybermen. However, reflecting on his past, the Doctor realised that he was just a man in a box who travelled around to help where he could, and then turned command of the army over to Danny, who led the Cybermen into the clouds, where they self-destructed and stopped the rainfall from converting the living. A devastated Missy told the Doctor he could find Gallifrey in its original location with coordinates she provided, but Clara threatened to kill Missy for what she had done, until the Doctor prepared to do it himself in order to "save [Clara's] soul". However, a rogue Cyberman disintegrated Missy instead, (TV: Death in Heaven) though the Doctor knew she had found a way to survive. (TV: The Magician's Apprentice) The Doctor realised that the Cyberman was his old friend the Brigadier and saluted him, fulfilling a lifelong wish of his old friend, who then flew away.
The Doctor later entered the coordinates Missy gave him into the TARDIS, but found out the coordinates were false and led to nowhere. With his only way to find Gallifrey gone, the Doctor attacked the TARDIS console in a furious rage, before breaking down emotionally. Meeting up with Clara in a café, and believing that she was back with Danny, who had the power to leave the Nethersphere when given control of the Cybermen, the Doctor lied to her that he had found Gallifrey so as to allow her to continue with her life. Upon hearing this, Clara told him that she was happy and ready to settle down with Danny, and they both bid farewell and parted ways. (TV: Death in Heaven)
Dreaming of Santa
Sometime later, the Doctor was attacked by a dream crab, which put him into a scenario where he was brooding alone in his drifting TARDIS, (TV: Last Christmas) and was snapped out of his funk when he heard Santa Claus knocking on the TARDIS door, asking the Doctor what he wanted for Christmas. (TV: Death in Heaven) The Doctor immediately travelled to Clara's home and collected her from her rooftop, where she had also encountered Santa. Urging her to believe in him, they arrived at a North Pole base, which they found was under attack from dream crabs. Santa arrived to help with the problem, but Clara was attacked by a crab and fell into a dream state. As no one could find a way to remove the crab from her face, the Doctor let himself be attacked by one to get her out of her dream before the crab could kill her.
Entering Clara's dream, the Doctor found she was dreaming of spending Christmas with Danny, and learned that Danny was dead. The Doctor urged her to break out of the dream, after Danny bid her farewell. Waking up in the base, the Doctor came to the realisation that everyone in the base was dreaming, having been attacked by crabs after they arrived. They woke up from the dream and the Doctor and Clara prepared to leave, but Clara reminded the Doctor of Santa having been on her roof, and he realised they were still dreaming from different places and times. The infected personnel in the base began to attack the survivors, but everyone managed to escape by dreaming Santa was flying them home. The Doctor, Clara and the base scientists flew over London as they each woke up back in their own times.
Waking up where he had been, the Doctor travelled to Clara's home and removed the dream crab attached to her, only to find it had been sixty-two years since he left her and she was now an old woman. Clara filled him in on the many things she had done in her years, but the Doctor felt remorseful of leaving her when he did. Santa suddenly appeared and asked the Doctor what he'd do if he had another chance, and the Doctor woke up from his dream, this time for real. He saved the younger Clara from the crab. Spurred on by what could have happened to her, the Doctor invited her to resume her travels with him, and she accepted. (TV: Last Christmas)
Second chance with Clara
The Doctor tried to throw Clara a surprise birthday party with varying incarnations and forms of herself, but after Clara noted the rules of time preventing one from meeting themselves, he admitted they were just disguised aliens. (COMIC: The Partying of the Ways) They next went to Cinema Paradoxo, which had every movie ever playing infinitely. The Doctor chose to see a silent film, which turned out to star actual Silents, resulting in them forgetting the film. (COMIC: Silver Screenesis) The Doctor and Clara admired some dogs, not realising that they were almost trapped in a time eddy by Zorgo. (COMIC: Zorgo the Terrible)
The Doctor and Clara attended an auction of the works of Lady Josephine and purchased a living animae particle portrait of her. (COMIC: Briarwood) Knowing that the portrait would eventually become Josie Day, a companion of his eighth incarnation, the Doctor left her in 21st century Wales in an old cottage of his, telling her the Eighth Doctor would show her the things she needed to see. The Doctor also left a to-do list in his copy of Jane Eyre for his eighth incarnation to find, knowing that the adventures would help Josie build her self-confidence and see herself as far more than a painting. (COMIC: A Matter of Life and Death)
The Doctor learnt that an invasion fleet of Megrati were planning to attack the planet of Lemaria, a plan he had previously stopped in his first incarnation, and sent them an invitation to give them some time to talk. While waiting for them to arrive, he took part in a Freedom Day celebratory play about the original defeat of the Lemaria, playing the role of the First Doctor. The Doctor realised his fifth incarnation, Adric, Nyssa and Tegan Jovanka were in the audience before the real Megrati arrived. As his past self and companions watched, the Doctor convinced the Megrati to leave the planet by threatening to destroy their ships, though revealed to the play's audience as the Megrati left that he was bluffing. (PROSE: The Constant Doctor)
The Doctor learnt from Hitch that a sentient super-weapon called the Hadax Ura had gone missing, with Hitch putting together a recovery team and needing the Doctor's technical expertise. The Doctor agreed to join the team, dragging Clara away from her class to assist. As the ship carrying the team headed for the planet carrying the weapon, Unnamed BX-4, the Hadax Ura shot the ship down, revealing the weapon's location, but everyone on board was able to escape with jetpacks. Clara was attacked by pterosaurs and dropped into the Jungle.
The Doctor went off on his own to look for Clara, and found Clara with an organic avatar who had taken on the appearance of Danny. The avatar told them that the Hadax Ura had been "devouring" the Jungle, and turning its indigenous life into an army, and asked them to either destroy the weapon or take it elsewhere. The Doctor realised that it intended to end the war between the Hub Alliance and the Axis Worlds, and the Hadax Ura began augmenting the crew to become its foot soldiers. Believing it had augmented Clara as well, the Hadax Ura had actually linked the Jungle's computer systems to its own after augmenting the avatar. The avatar appeared to shut down the Hadax Ura and its augmented soldiers, but the Hadax Ura had tricked Hitch's team to bring it on board the lander as a means of escape for the Hadax Ura. The Doctor took his jet pack to infiltrate the lander, and found the Hadax Ura had taken over Hitch's body. Realising that Hitch's mind had been completely overwritten by the Hadax Ura, the Doctor ejected the Hitch's body out of the lander's airlock, burning the Hadax Ura up on re-entry unprotected. (COMIC: Spirits of the Jungle)
The Doctor and Clara arrived inside the observation capsule Genetrix above Venus, but the capsule separated from the Lovell Platform when the tether connecting them broke. The Doctor discovered that the gas samples taken by the crew were actually the indigenous life form on Venus, and that the separation was a result of a liberation attempt, and ordered the samples to be released. Grateful for their freedom, the Venusians lifted the pod to safety. (PROSE: Sunset Over Venus)
The Doctor and Clara arrived in 2015 London to find it as a burnt wasteland with traces of human DNA amongst the ashes. While Clara went exploring, the Doctor was attacked by a man, who warned him "the scorched" were rising after the Doctor subdued him with Venusian karate, only for him to be possessed by Hyperions. The Doctor then found himself facing many Hyperion-possessed humans, but was able to defeat them with the help of Clara and Sam, a firefighter. Sam brought the Doctor and Clara to the London Underground, where people had taken refuge from the Hyperion invasion. The Doctor, reappointed by UNIT as President of Earth, learnt that the Hyperions had divided England up with firewalls, particularly operating machinery in Sussex.
The Doctor, Clara and Sam bypassed the Sussex firewall with the TARDIS and found that captured humans were being enslaved by the Hyperions to build a fusion web. Clara tried to intervene, but in doing so caused Hyperion "angels" to appear. Fleeing back to the TARDIS, an angel got on board, but Sam knocked her out by spraying her with a fire extinguisher. Deducing that the angel had been transmogrified by the Hyperions, the Doctor bio-linked her to the TARDIS telepathic circuits to restore her human consciousness. The TARDIS materialised by the sun, where the Hyperions were building the fusion web to consume its energy. Although the Doctor believed they were out of range, the web was already powerful enough to attack the TARDIS.
Dra-Khan, a Hyperion warlord, stormed the TARDIS and revealed the Hyperions survived the destruction of Hyperios by hiding on Neptune. The angel, in actuality the reanimated human Weir, regained her consciousness and attacked Dra-Khan and the other Hyperions, driving them away. The Doctor persuaded Weir to join their side, and after defeating an onslaught of Scorched in London, revealed he had weaponised a cold bomb to defeat the Hyperions. Back at the Sussex firewall, the Doctor released the human slaves from captivity as Clara and Sam attacked the base. Sam attempted to detonate the cold bomb, but it failed and he was killed. The Doctor conceded that the Hyperions had won, as the fusion web was completed. But when it was activated, he revealed that the bomb had merely been a distraction so that he could hack the TARDIS into the web and pull the Hyperions five billion years into the future, where the sun died. As the web began collapsing, the Doctor and Clara escaped to the TARDIS as Weir held off the Hyperions. However, unwilling to let anyone else die after Sam's death, the Doctor pulled Weir's psychic essence from the TARDIS' telepathic circuits, allowing her presence to be with her family. (COMIC: The Hyperion Empire)
Arriving on the SS Berry Gordy in the 53rd century, the Doctor and Clara saved pop-star India Summer from being kidnaped by a band of Skinks hired by her manager, Gavor Vek-Haart. (COMIC: Hyperballad)
The Doctor and Clara responded to a party invitation from Susan Foreman, only to discover they had been lured into a trap by the Celestial Toymaker, who explained that his Toyroom was breaking down from old age, and that he had entrapped the Doctor for help. Seeing a kinship with his enemy, the Doctor relinquished his TARDIS to the Toymaker, knowing that it was the only way to help him. Escaping to the control room, the Doctor jettisoned the Zero Room with the Toymaker still inside, allowing the Toymaker to have it as his new Toyroom. (COMIC: Relative Dimensions)
A force brought the TARDIS off course, where it was forced to land on a place the Doctor nicknamed "Planet Wet". When the Doctor exited the TARDIS, the hillock swallowed the TARDIS whole, and the Doctor was forced to find his way to a building, where he found the TARDIS was being held in an online auction by GalMart when it was claimed as salvage. During the bid, the Doctor pointed out that he still had the key on him, leaving the winner WinnerBoi with a ship he couldn't access. While pretending to hand over the deed of ownership to GalMart, he instead wrote a Trojan virus in Ancient High Gallifreyan to infest the GalMart systems. He compelled the GalMart computer to purchase the anti-Trojan, and to declare the TARDIS as a bootleg or counterfeit item, but to transfer the money to WinnerBoi for the amount he had paid to buy the TARDIS. (PROSE: Buyer's Remorse)
Coming to pick up Clara, the Doctor was persuaded to play boards games instead. Losing, the Doctor repeatedly went back in time to the moment he arrived so he could win a game before Clara; this desire consumed him, resulting in the Doctor making over eighty-seven attempts and becoming heavily ragged before he finally won a match. Unaware of the Doctor's actions, Clara headed for the TARDIS. (COMIC: The Board Games)
The Doctor arrived on the hospital planet Gehenna while it was under siege from the Weeping Angels in the form of a marble dust storm that spread a plague that turned others into Weeping Angels, and discovered that Chief Medical Officer Perinne had been keeping an Angel prisoner for experiments, with the networked Salus masks the medics wore creating a Weeping Angel virus. Unable to salvage the situation, Perinne forced the Doctor to leave as he succumbed to the Angels' virus. (PROSE: Grey Matter)
While looking for a bookshop, the Doctor found himself on a battlefield during the Thousand Year War on Skaro, and encountered a young boy trapped in a field of Handmines, and, during the rescue attempt, learned that the boy was Davros. When he "should have been brave enough, [and] strong enough to do something better", the Doctor fled the battlefield, unwilling to save or kill the boy who would create the Daleks. Afterwards, an older Davros, having become "very sick", asked to see the Doctor "while there [was] still time", (TV: The Doctor's Meditation, The Magician's Apprentice) and sent Colony Sarff to search for him. The Doctor prepared a confession dial to be delivered to Missy, and went to the planet Karn to meet with Ohila and the Sisterhood of Karn. After hiding from Colony Sarff behind a rock, (TV: The Magician's Apprentice) the Doctor was told by Ohila that he owed Davros nothing by partaking in a confrontation, warning him his actions would spell his end. Giving Ohila his confession dial before departing, the Doctor proclaimed that he would find a rock to meditate on in preparation for his possible destruction. (WC: Prologue)
Travelling to Essex in 1138 A.D., (TV: The Magician's Apprentice) the Doctor gained a servant in Bors when he removed a splinter from him. After three hours of meditation in a castle, (TV: The Magician's Apprentice) during which he thought back to his previous incarnations, (PROSE: Full Stop) the Doctor decided he needed better drinking water, and gathered the locals to dig a well. After eleven days of finding a supply of water, and another day to construct the well, the Doctor, rather than resume his meditation, decided to make improvements to the castle, such as adding a sunroof to the throne room, (TV: The Doctor's Meditation) building a first-class, child-friendly visitor centre, teaching the locals mathematics and introducing the word "Dude" to the 12th century. (TV: The Magician's Apprentice) While additions to the throne room went underway, the Doctor had a conversation with Bors about him avoiding his meditation. Four days afterwards, the Doctor finally decided to begin mediating again before leaving the next day, and also divulged to Bors the reasons he had for being reclusive. (TV: The Doctor's Meditation)
For his last day at the castle, the Doctor decided to have an axe fight with Bors, and arrived on a tank playing an electric guitar. While trying to get the crowd to understand his jokes, he realised Clara and Missy had tracked him down, whereupon Bors was attacked by Colony Sarff, who demanded that the Doctor attend to Davros. Reminded of his shame at leaving the young Davros behind, the Doctor reluctantly agreed to go as a prisoner, with Clara insisting she and Missy be taken prisoner too. Sarff brought the trio to Davros' infirmary, where he was dying. While Clara and Missy were left in a cell block, the Doctor went to see Davros, who revealed to the Doctor that they were on Skaro. On a monitor, the Doctor saw that Clara and Missy had escaped their cell and been captured by the Daleks, who had also procured the TARDIS. Missy was seemingly exterminated as she tried to convince the Daleks to work with her, with Clara quickly being exterminated as well and the TARDIS was seemingly destroyed. (TV: The Magician's Apprentice)
As the TARDIS was redistributed, (TV: The Witch's Familiar) Davros mocked the Doctor for his compassion towards others resulting in his victory against him, (TV: The Magician's Apprentice) but the Doctor, wielding a Dalek gunstick, ignored Davros and forcibly removed him from his chair so he could ride in it and be safe from the Daleks' firepower. He then headed to the congregation of Daleks, and mocked them for being unable to shoot him when they tried. After his demand to know what happened to Clara was answered by the Supreme Dalek in confirmation of her demise, the Doctor was restrained by Colony Sarff and brought back to Davros's infirmary, where Davros revealed that he was able to sustain his life by siphoning off the Daleks' heartbeats through his life support system, and offered to give the Doctor control of this to commit unprovoked genocide upon the Daleks. Though tempted, the Doctor chose to be compassioned and refused to act, taking the opportunity retrieve his sonic sunglasses when Davros presented him with his confessional dial.
Fully convinced that Davros was truly dying when the Kaled scientist looked upon him with his real eyes, the Doctor decided to give Davros his last wish of seeing the sunlight with his true eyes one last time. When Davros could no long keep his eyes open by the time the sun rose, the Doctor proceeded to give Davros a bit of regenerative energy, but was seized by Colony Sarff and drained to regenerate Davros and all the Daleks on Skaro. He was saved when Missy killed Sarff, and revealed to Davros that he had guessed his plan all along and had tricked Davros; the regenerative energy Davros had used to renew himself and his creations had also been distributed through the sewers beneath the city, and the decaying remains of the ancient Daleks they contained had awoken and begun to emerge. While fleeing the city, the Doctor and Missy came across a Dalek that Missy claimed had killed Clara. The Doctor demanded the Dalek tell him if this was true, but the Dalek kept babbling incoherently. When it began to beg for mercy, the Doctor, suspicious, demanded it open its casing, and found that Clara had been trapped inside the Dalek by Missy, and the Doctor told her to run as he freed Clara.
The Doctor and Clara then entered the room housing the congregation of Daleks, and the Doctor used his sonic sunglasses to rematerialise the redistributed TARDIS and flee. As he and Clara watched the Dalek City crumble, the Doctor realised that he could teach mercy to the young Davros. (TV: The Witch's Familiar) Armed with the Dalek gunstick, the Doctor returned to the misty battlefield as the young Davros cried for help, (TV: The Magician's Apprentice) and saved him by firing on the Handmines. When questioned whether he was the enemy, the Doctor told Davros that friends and enemies didn't matter "so long as [there was] mercy," and then lead the boy to his home. (TV: The Witch's Familiar)
Continued adventures with Clara
Returning to Coal Hill School to pick up Clara, the Doctor found the world had been gassed into a deep sleep by the Somnosian Empire. Using an antidote to awaken the populace, the Doctor allowed the Somnosians to retreat when the armed forces arrived. (COMIC: Beauty Sleep) The Doctor and Clara then continued their travels together, encountering "monsters, [and] things blowing up," and also visiting a place where people with long necks had celebrated New Year's Day for two centuries. (TV: Under the Lake)
Ghosts on the Drum
Arriving in an underwater base called the Drum in 2119, the Doctor found that the TARDIS was "unhappy" with her surroundings, and he and Clara then wandered around the base to find it empty with signs of a struggle. Seeing two apparitions of a Tivolian and human male, they stumbled upon a spaceship marked with foreign wording, which the Doctor found untranslatable. The apparitions then chased the Doctor and Clara to a Faraday cage, containing the base's crew; Cass, Tim Lunn, Alice O'Donnell, Mason Bennett and Richard Pritchard. Using his UNIT credentials to gain their trust, the crew explained to the Doctor that the man, Jonathan Moran, had been their captain before his death, and that they had been menaced by the apparitions only at the night since discovering the ship, which lead then to believe that they were ghosts, which the Doctor debunked.
As the Drum entered day mode, the Doctor learned more about the base from the crew, and further investigated the spaceship, discovering that one of the power cells was missing and a suspended animation chamber was unaccountable. After re-evaluating the situation caused the Doctor to conclude that the ghosts were genuine, the Drum's night mode was activated by the ghosts, and the Cloister Bell began to ring. With Prichard killed by Moran, and the ghosts trying to lure a medical team to the Drum, the Doctor ordered the base be locked under quarantine and encouraged the surviving crew to help him capture the ghosts.
Trapping the ghosts in the Faraday cage, the Doctor found they were repeating coordinates to the flooded town's church, and that the ghosts had been artificially created to act as a homing beacon. After Bennett retrieved the ship's suspended animation chamber, the Doctor found that the coordinates had been the symbols within the spaceship, and decided to go back in time to before the town's flooding to find the truth of the matter. As the Doctor, Clara and the crew made their way to the TARDIS, the ghosts began flooding water into the Drum, resulting in emergency doors coming down and splitting the group in half. Clara was trapped in the base with Cass and Lunn, while the Doctor set off in the TARDIS with O'Donnell and Bennett. (TV: Under the Lake)
Arriving in 1980, the Doctor, O'Donnell and Bennett encountered the Tivolian, Albar Prentis, while he was alive, using the spaceship, which had yet to have the wording inscribed, as a hearse to transport a dead warlord known as the Fisher King. Wanting to destroy the signal, the Doctor demanded Prentis hand over the device broadcasting, but Prentis was oblivious to what the Doctor was talking about. Contacting Clara, the Doctor found that a ghost of himself had appeared in 2119, mouthing the names of the dead and those yet to die, with Clara second after O'Donnell. The Doctor was shaken at the prospect of him dying, but, despite Clara's urging to change time, he insisted he had to die. The Doctor's ghost then entered the Drum and released the other ghosts, forcing Clara, Cass and Lunn back to the Faraday Cage, where the phone signal was cut off. Before they left, however, the Doctor was able to get a look at his ghost and see him change his message.
Realising O'Donnell was going to die, the Doctor and Bennett tried to persuade her to stay in the TARDIS, but she refused. Returning to the ship, the trio found Prentis dead, the writing written and themselves being hunted by the Fisher King. Pursued into a building, O'Donnell was separated from the group and killed by the Fisher King, fulfilling the Ghost Doctor's prophecy. The Doctor and Bennett then tried to go back to the future to save Clara from being killed, but the TARDIS instead sent them back in time by thirty minutes, where the Doctor had to force Bennett from interfering in Prentis and O'Donnell's deaths. Sending Bennett back to the TARDIS, the Doctor set one of the ship's power cells to destroy the dam above the town. Confronting the Fisher King, the Doctor was informed that the ghosts were signalling to the Fisher King's armada to rescue him and enslave the Earth. Just as he was about to be shot, the Doctor lied about erasing the writing from the ship, provoking the Fisher King to return to the ship, just as the power cell exploded, wrecking the dam wall and flooding the town. Before the flood hit the church, the Doctor got into the Fisher King's stasis chamber, protecting him as the Fisher King drowned in the flood. (TV: Before the Flood)
In 2119, the pod was recovered by Bennett and brought upon the Drum to be examined by the past Doctor. (TV: Under the Lake) Using his sonic sunglasses to connect with the Drum's Wi-Fi, the Doctor created a hologram of himself as a ghost "with a soupçon of artificial intelligence, and a few pre-recorded phrases thrown in," (TV: Before the Flood) which appeared before Clara, Lunn and Cass almost immediately after the past Doctor left the Drum with Bennett and O'Donnell. (TV: Under the Lake) Using the hologram as an avatar, the Doctor gave Clara the list he had heard her give him from the ghost, and released the other ghosts from the Faraday cage, telling his past self via Clara's phone that "the chamber will open tonight." Conversing with other ghosts, the Doctor set them on Lunn, knowing they wouldn't kill him, to set a trap for Clara and Cass in the cantina.
When the chamber opened, the Doctor used his ghost hologram to lure the other ghosts to the Faraday cage with the "call of the Fisher King." Erasing the writing from their minds, the Doctor revealed to Clara, Cass and Lunn that his ghost was just a projection, and told them and Bennett that UNIT would dispose of the ghosts by removing the Faraday cage from Earth's orbit. As he and Clara set off in the TARDIS, the Doctor told her he only knew what to make the fake ghost say because she told him what it was saying, calling it a bootstrap paradox. (TV: Before the Flood)
Events on Karaoke
The Doctor dropped Clara off on Planet Karaoke while he stayed inside to do repairs on the TARDIS, but Clara exited the ship before he could warn her that he would be momentarily shutting the TARDIS down, leaving the translation circuits off. (COMIC: Day of the Tune) As Clara did not hear his warning, she began singing on the stage, where the TARDIS translation began to fail as she could no longer read the lyrics on screen. She tried singing anyway and accidentally insulted the planet's monarch in Karaeokean, and she and the Doctor were arrested. (COMIC: The Meddling of Clara's Song)
The two were given a chance of survival by forced entry into Battle of the Bands Beyond the Stars, a musical competition. If their performance was deemed poor, they would be killed. As the two nervously prepared for this competition, they were passed by a band formed of what appeared to be Headless Monks. However, these robed figures soon removed their hoods, revealing themselves to be various incarnations of the Master led by Missy. (COMIC: The Abominable Showmen) Correctly deducing that Missy planned to use hypnosis to take over the minds of the viewers watching the program, the Doctor chose not to intervene, knowing that it was impossible for the many egos of the Master to work together as a team. Sure enough the four Masters began to fight Missy for her device, and were disqualified for failing to do their performance.
The Doctor and Clara then prepared for their performance, the Doctor confident that he could pull it off. (COMIC: The Five Masters) As the Doctor was about to perform, Clara disconnected some power cables, allowing them to escape the stage and get back to the TARDIS. Clara wondered how they would be able to stop the show, but the Doctor told her that after the instalment they had just ruined, the show was cancelled due to all-time lowest viewing figures. They then set off to get chips together. (COMIC: One! Two! Three! Four! To Doomsday)
The Doctor and Clara ate the chips sitting on the TARDIS, which was parked in the Blue Lagoon Nebula. When Clara asked if their adventures would ever stop, the Doctor explained that adventure was just life without the boring bits, which he always tried to avoid whenever possible. They were both unaware that they were about to be eaten by a giant space turtle... (COMIC: Epilogopolis)
Final adventures with Clara
The Doctor and Clara arrived in Highgate Cemetery in 1972, where, intruding upon a cult meeting, they were attacked by vampire-like creatures called the Corvids, which petrified the TARDIS and fed on people's psychic essence, but were trapped inside the cemetery. The Doctor discovered that Clara's exposure to his time stream had rendered her toxic to the Corvids' powers, and that exposing themselves to her left a psychic corridor open. Using the psychic signature of the dead amplified by the ley line the cemetery was built on, the Doctor banished the Corvids back to the Time Vortex with the aid of Jess Collins. (COMIC: The Highgate Horror)
After saving Zeltran Beta from an invader with a Chaos ray, the Doctor was informed that his activities had been advertised. Tracking the advert to Sterlana, the Doctor was greeted by Zip Betterblast, who introduced himself as the Doctor's self-appointed agent and had his robots give the Doctor a costume change for an interview. Cutting the interview short to deal with a Andromedan Feline Gigantoform, the Doctor used his sonic sunglasses to stun the beast, and then discovered that Betterblast had used cybernetic implants to control the Feline Gigantoform. Exposing Betterblast to the public for the Shadow Proclamation to arrest him, the Doctor reclaimed his clothes and left with Clara to get coffee. (COMIC: Time and PR in Space)
After saving the Velosians from being attacked by "four and a bit battle fleets" and rescuing Clara from being killed by a Love Sprite from the Spider Mines, the Doctor and Clara landed on Earth, where they were promptly captured by Vikings and taken to their village on a two days' longboat journey from the TARDIS. When a race called the Mire attacked the village, killing all of the warriors, a girl named Ashildr declared war between the village and the Mire. After failing to train the farmers in the village to fight, the Doctor realised the village farmed electric eels, enabling him to formulate a plan to defeat the Mire.
When the Mire arrived, the Doctor and the farmers distracted them with a party in a barn, while the other villagers used the eels to electrocute four of the Mire and remove their armour and weapons. Seizing the opportunity, the Doctor gave one of the helmets to Ashildr, who used it to feed the image of a dragon into the technology of the Mire's helmets, scaring them off, when the dragon was actually nothing more than a puppet. The Doctor revealed to the Mire leader that Clara had filmed them being scared away by the villagers and threatened him and to leave lest the video be released to the Galactic Hub and ruin the Mire's reputation. The Mire promptly left, but the celebrations ended when it was discovered that Ashildr had died of heart failure as a result of using the Mire helmet.
The Doctor moped in a barn, regretting being unable to save Ashildr. However, after voicing his pain to Clara, he realised that he shared the face of Lobus Caecilius, whom he had saved from a fixed point in time during his tenth incarnation, and concluded that his face was a reminder to himself that he should always save people. Using a Mire repair kit from the Mire helmet, the Doctor revived Ashildr, and left her a second kit for whoever she wanted. Heading back to the TARDIS, the Doctor, now reflecting poorly on his actions, told Clara that the kit would have given Ashildr immortality, and then realised that he had also made her a hybrid. (TV: The Girl Who Died)
Sometime after leaving Scandinavia, Clara asked the Doctor to help her student Evie Hubbard with an assignment of an imaginary interview with Winston Churchill. Not realising Clara simply wanted him to tell Evie about him, the Doctor took Evie back in time to talk with Churchill in-person. Later, while Clara was taking her Year Seven class to their tae kwon do lessons, (TV: The Woman Who Lived) the Doctor conducted the Last Night of the Proms, where he ended up playing the Sex Pistols version of "God Save the Queen", (COMIC: Clara Oswald and the School of Death) and also decided to check on Ashildr's immortal life. One of the acts he observed was Ashildr founding a colony of lepers. (TV: The Woman Who Lived)
Getting trapped in a room of metal on fire, the Doctor sent his sonic sunglasses down to Earth, where they were found by a father out walking with his son. When the father put them on, they activated the Telepathic Emergency Beacon, allowing the Doctor to take control of his body and pilot the TARDIS to free himself. As a reward, the Doctor allowed the father and son a free trip, which the father used to pick up his wife, who had apparently disappeared months earlier. (PROSE: My Dad, The Doctor)
After spending weeks following exoplanetary energy on his curioscanner across the galaxy, the Doctor traced the Eyes of Hades to 1651 England, where he found a highwayman called "the Knightmare" robbing the carriage holding the artefact. The Doctor's intervention resulted in the carriage escaping before either of them could get the Eyes, and the Knightmare revealed herself to be Ashildr, who was now addressing herself as "Me" after losing most of her childhood memories due to her long lifespan. At "Lady Me's" mansion, Ashildr told the Doctor of her exploits, and begged him to take her with him in the TARDIS, but he refused. Instead, the two teamed up to steal the Eyes of Hades from Lucie Fanshawe by breaking into her mansion.
The Doctor then found that Ashildr had an ally in Leandro, who owned the Eyes of Hades and needed a death to activate it to open a portal for him and Ashildr to escape Earth in. Upon learning the highwayman Sam Swift was to be executed, Ashildr and Leandro set off to use his death to activate the artefact. While the Doctor tried to call off Swift's execution, Ashildr forcibly attached the Eyes of Hades to Swift, opening the portal. Leandro then revealed that he had only used Ashildr to get the portal open and allow his people to invade, and the Leonian ships began attacking the peasants. Realising her mistake, Ashildr used the second Mire kit to revive Swift, closing the portal and ending the attack. For his failure, Leandro was incinerated by his people. In the aftermath, Ashildr accepted her inability to travel with the Doctor and told him she would look out for other people he left behind, and they parted on relatively good terms
When the Doctor picked up Clara for more adventures, she presented him with a selfie from Evie Hubbard, and the Doctor noticed Ashildr in the background of the photo. Shaking it off, he and Clara took off for "somewhere magical." (TV: The Woman Who Lived) The Doctor continued to keep surveillance on Ashildr, but lost track of her in the early 1800s. (TV: Face the Raven)
Receiving a call from Osgood about the "Nightmare Scenario", the Doctor discovered that the ceasefire between the humans and Zygons had been breaking down since Missy murdered one of the Osgoods, and tried to confront the Zygon High Command about it, only for them to be kidnapped by Zygon rebels, just as Kate Stewart phoned him to inform the Doctor of Osgood's kidnapping. Meeting up with Clara and Kate at Zygon High Command base at Drakeman Junior School, the Doctor communicated with the control polyp and witnessed the rebels execute the Zygon High Command. Sharing thoughts with Kate, Clara and Jac, the Doctor sent Kate to investigate Zygon activity in the New Mexico town Truth or Consequences, and left Clara and Jac in charge of defending England while he took Boat One to the Zygon settlement in Turmezistan to rescue Osgood.
The Doctor and Colonel Walsh led a platoon of UNIT soldiers to retrieve Osgood from the Zygon base before it was destroyed in an air strike, but the leading soldier fell for the Zygons' deceptions and lead the platoon to their deaths in an ambush. As Walsh left to observe the settlement get destroyed, the Doctor found Osgood and managed to capture a Zygon. Aboard Boat One, the Zygon informed the Doctor that the Zygon invasion of Earth had already taken place. As the plane returned to the United Kingdom, "Clara" phoned the Doctor, and, claiming that the real Clara and Kate had been killed and replaced, fired a rocket launcher from the ground at Boat One. (TV: The Zygon Invasion) The Zygon missed her first shot, which gave the Doctor and Osgood enough time to parachute out of the plane before she fired a successful shot. They landed safety and received a text from Clara's phone, confirming that she was alive and fighting the Zygon in her form. Calling the Zygon, who had named herself "Bonnie", the Doctor retrieved a message from Bonnie's winking eye, controlled by Clara inside the pod, that confirmed her location, and, pursued by policeman he thought were Zygons, commandeered a van to get him and Osgood back to London.
They drove to a south London shopping centre where a Zygon had been forced to normalise himself by Bonnie and, despite the Doctor pleading him not too, committed suicide because he didn't want to be a part of the Zygon rebellion. Kate and two UNIT soldiers then turned up, and told the Doctor where to find Clara and the Zygon rebel base. Arriving at the Zygon stronghold, the UNIT soldiers revealed themselves to be Zygons and Kate contacted Bonnie, who had taken Clara with her to the Black Archive to activate the Osgood Box. However, Bonnie then revealed that the Doctor had put two Osgood Boxes in place with safeguards in order to keep the human-Zygon ceasefire, and demanded the Doctor be brought to her. Kate, however, revealed herself to be the genuine Kate, killed the Zygon soldiers and destroyed the communicator.
Arriving at the Black Archive, Bonnie and Kate both threatened to use the Osgood boxes, but the Doctor used his memories and feelings of the Time War to persuade them that they could end the conflict in a more humane way. Moved by his speech, Kate decided not to use the boxes, and Bonnie realised they were empty. To keep the boxes' secret safe, the Doctor erased the memories of Kate and Bonnie's Zygon guards, but allowed Bonnie to keep her memory of the event. As the Doctor and Clara prepared to leave, the Doctor invited Osgood to join him in his travels, but she denied as she had the boxes to look after. Both she and Bonnie, who was now using Osgood's form, continued the task of protecting the Osgood Boxes and maintaining the human-Zygon relations together. (TV: The Zygon Inversion)
After thwarting a run-in with the warlord Lucifer van Volk, who accused him of magnetising his mercenary army at some point in his future, the Doctor returned to 2015 to find that Clara had taken a leave of absence from Coal Hill and travelled to Ravenscaur School in Scotland to investigate the disappearance of her friend Christel. While Clara took over Christel's vacated job as an English teacher, the Doctor went undercover in the local town, where he found the townspeople were a disguised race of aliens plotting against humanity. Deducing that Ravenscaur was the centre of the plan, he instructed Clara to remain undercover at the school while he worked out what they were dealing with.
Believing that the Sea Devils were behind the plan, the Doctor explored the catacombs of Ravenscaur to confirm his suspicions and ended up rescuing Clara and two students, Lucy Walker and Jack Irvine, from the Sea Devils. The group returned to the school only to be captured by the headmaster, Mrs. Mariner, who revealed she and many of the school's students and facility were disguised Sea Devils, as well as the visiting Prime Minister, Daniel Claremont. They were plotting to use humanity's global warming against them to create a perfect environment for their race. While Claremont was giving a televised press conference at the school, the Doctor set off the school's sprinklers, causing the disguised Sea Devils to revert to their normal forms. Mariner, however, commanded all Sea Devil bases to rise, revealing they had the machinery ready to wipe out humanity.
The Doctor equipped Clara, Jack and Lucy with neural enhancers, allowing them to use their telekinetic power to combat and escape the Sea Devils. Ordering Clara to evacuate the school, he navigated to the rooftops to confront Mariner, but was too late to prevent her from ordering the troops to rise. The Doctor altered the trajectory of their devastation pulse so that their weapons would attack Raven's Isle rather than the mainland. As the school and Sea Devils were destroyed, Clara, still equipped with her neural enhancer, flew in and rescued the Doctor from the destruction. As the two left in the TARDIS, the Doctor asked Clara if she wanted to go home, but she replied that being with him was home. (COMIC: Clara Oswald and the School of Death)
The Doctor and Clara arrived in a forest on a planet, where the TARDIS was stolen by dragons. Navigating to a nearby village, they learned from the Lord Mortigan that they were on a planet designed to resemble medieval times, with the dragons being the planet's natural inhabitants, which had been genetically modified. The dragons had been freed from being inhibited by inhibitor chips by a person known as the Dragon Lord, who aimed to wipe out the townspeople, having already killed the royalty. The Doctor, Clara and the town's remaining lords set off to reason with the Dragon Lord. Along the way, they ran into a baby hatchling, but Lord Mortigan killed it, causing its parents to attack the party. The Doctor was separated from Clara in the chaos, and found a dragon which had been injured by a booby trap.
The Doctor found that the dragon did not possess a chip, casting doubt over his belief that the Dragon Lord was controlling them. Reuniting with Clara at the Red Castle, they found that the Dragon Lord had been killed, believing they would have been grateful to him for liberating them. The Doctor and Clara retrieved the TARDIS from the dragons' treasure hoard and left, calling rescue ships to evacuate the planet of humans to allow the dragons to live in peace. (COMIC: The Dragon Lord)
The Doctor and Clara were summoned by Harry Houdini, and found themselves in a crystalline computer program inside a crystal ball which fed on their despair. The program set up theatrical death traps with no way out so their minds could be ripened for it, but the Doctor, Clara and Houdini escaped, and the Doctor revealed the virtual environment with his sonic screwdriver. The Doctor, Clara and Houdini then fought back by imagining what made them feel the most free, which shattered the prison and returned them to the real world. They found the owner of the crystal ball prison, Diamanda, had been completely consumed by the crystal ball's power and killed. When Houdini regretted his inability to commune with the dead, the Doctor and Clara reassured him that his legacy would be remembered forever. (COMIC: Theatre of the Mind)
While preparing for a holiday, the Doctor and Clara found themselves having to travel down the Doctor's timeline to prevent time flies sent by the Time Weaver Ethel from unravelling the Doctor's life in retaliation for him landing his TARDIS on her sister. After saving his eleventh and first incarnations, the Doctor was assisted in defeating Ethel by her other sister, Gretel. (COMIC: A Stitch in Time)
In a frontier town in 1849 California, the Doctor prevented an alien criminal from using prospector Josh Langham to construct a body from scrap metal to house its displaced mind. When the criminal refused his offer to return it home due to being in exile, the Doctor lured it over the edge of a precipice, where the creature's mind dissipated into the air after its body was destroyed. (PROSE: All That Glitters)
Unable to go to the Castles of Trutalia due to his TARDIS being clamped by an out-of-date Ministry of Time robot, the Doctor went to Garage 10 to get the parts needed to fix the robot. En route, he befriended a mechanic enthusiast named Athena, and, working together, the pair learned that the owner of Garage 10 was stripping his customers of their identity to recruit them and sell their memories. Undoing the owner's actions, and getting him arrested by the Judoon, the Doctor parted ways with Athena to update the Ministry of Time robot into having its own sense of adventure. (COMIC: The Ministry of Time)
The Doctor found a giant robot and kaiju fighting in a Japanese city, and that UNIT soldiers, led by Colonel Ishiguro, were preparing to attack them. Persuading Ishiguro to halt the attack, the Doctor discovered that they were the result of a stolen Kaznak Simu-system being used by Professor Nakatomi for his video game company. Overriding the data core with his own mind, the Doctor ended the fighting before UNIT needed the intervene, and went with Ishiguro for some noodles. (COMIC: Big in Japan)
The Doctor liberated the Seymour family from the Belamine while they were being assessed in preparation for an invasion of Earth, and erased his presence from the Belamine ship's systems, tricking the Belamine into thinking the human race was too formidable to attack and cancel their invasion. Before the Belamine retreated, the Doctor used their teleportation system to take the Seymour family back to the Oregon Trail. (PROSE: Off the Trail)
While visiting 1902 New York City, the Doctor learnt of ghost sights in a new subway tunnel, and, convincing the subway boss that he was a renowned psychic investigator, led a team of men to uncover the mystery. While many of his team fled at the sight of the ghosts, the Doctor and his only remaining help, Tom, found an alien tourist ship that was projecting ghosts to protect itself, its occupants having long died in malfunctioning sleep pods. The Doctor managed to fix the ship's systems and set it on a course back to its home planet. (PROSE: Ghosts of New York)
While preparing his entry for The Great Martian Bake-Off during a phone call with Clara, the Doctor went to the Halloween Fayre at Coal Hill School after Clara had gone missing. Finding superstitions coming true, the Doctor followed clues to find what happened to Clara, and found a mischievous time traveller named Miss Chief , who told the Doctor that she sent Clara back in time to the Witchfinder General Matthew Hopkins, who threw Clara into the water to see if she was a witch. After Miss Chief saved Clara's life, she and the Doctor played a space-time scavenger hunt game that the Doctor won, with his prize being told Clara's whereabouts.
When the Doctor came to rescue Clara, she accidentally named him as a witch, and both of them were to be executed, but Miss Chief brought them back to the 21st century before they could be hanged. The Doctor and Clara convinced Miss Chief to bring them back to retrieve the TARDIS and save a falsely accused woman named Agnes Leech from the dungeons, and unwittingly brought the missing cat, Smudge, with them. Clara convinced the mob that Hopkins was a witch and Smudge was his familiar, but the Doctor prevented them from murdering Hopkins by sneakily putting Miss Chief's time travelling marotte in his belt, forcing Miss Chief to save his life. The Doctor and Clara escaped, and returned to Coal Hill, where, due to the Doctor and Miss Chief bringing extinct animals and rare artefacts as part of the scavenger hunt, the Halloween Fayre made the the school enough money to fund the Danny Pink IT Suite, which was opened by Clara and the Doctor a few months later. (COMIC: Witch Hunt)
The Doctor and Clara landed on the space station Le Verrier in the 38th century, and joined a rescue crew that were looking for the station's crew. Attacked by Sandmen, the group ran into a laboratory housing Morpheus pods and, after rescuing Clara from one, found Professor Gagan Rassmussen hiding in a pod. After questioning Rassmussen on his pods, the Doctor concluded that the Sandmen were made up of sleep dust, and a direct result from use of the pods. As they made their way to destroy the pods, the station's gravity shields failed, Rassmussen was killed by a Sandman, and the Doctor, Clara and Chief Nagata became separated from the group after the Doctor rebooted the gravity shield. Re-evaluating the situation, the Doctor hacked into what he believed to be the rescue crew's helmet cams to review the footage, only for Nagata to reveal that none of them were wearing cameras. The Doctor then realised that the sleep dust in the air was being used as cameras to store images of the rescue mission, and that Rassmussen was behind the entire thing. Going to the crew's rescue ship, the Doctor, Clara and Nagata found Rassmussen had plans to spread the Sandmen to other planets. Surviving Rassmussen's attempt to kill them with his Patient Zero, Nagata killed Rassmussen, and the trio fled the station in the TARDIS, intending to destroy all Morpheus machines to prevent any more Sandman conversions. The Doctor, however, was confounded by the loose ends and how choreographed the event had been. (TV: Sleep No More)
The Doctor and Clara tracked mysterious energy fluctuations and disappearances to a comic store in London, where the Doctor was sucked into a comic book. Clara found that the missing people had also been pulled into comic books, and that the Boneless were the culprits. From within the comic, the Doctor told Clara to use the TARDIS' telepathic circuits to create a spatial and temporal flux. Teaming up with Natalie, a girl who was also trapped in his comic, the Doctor encouraged all the trapped people to use their love of comics to telepathically break free, imploding the Boneless back to their dimension and returning the victims to the real world. (COMIC: The Fourth Wall)
While Clara attended an end-of-term Christmas party, the Doctor met a young Clive Finch on Christmas Eve 1979, and took him to see the Loch Ness Monster, during which the Doctor encountered the Monk and thwarted his latest scheme. The Doctor partially wiped Clive's memory of the event, but left just enough of a recollection that would kick-start the boy's life of trying to find the Doctor again. (PROSE: The Persistence of Memory)
While visiting Florida's Adventure World theme park in 2017, the Doctor discovered that a businessman from the planet Bellcazario named Tunbridge was siphoning human life essence in the Space Plunge ride to sell to his people as a revitaliser. However, the Doctor had reversed the machine to reroute the stolen energies back to their original hosts before confronting Tunbridge, who made to flee in his ship, not realising that the Doctor had sabotaged it to drain his energies while he rode in it. (PROSE: Taking the Plunge)
When the TARDIS landed during the Battle of New Orleans due to a malfunction, the Doctor was mistakenly taken by Guide Mellors to her ship to watch the battle between the American and English forces behind a shimmer screen. While he disagreed with Mellors's business, the Doctor still assisted her in preventing a robot murdering the Throne Lord of Cassakna. (PROSE: Spectator Sport)
The Doctor arrived in an empty school during 2115 Christmas time and met Ross McNamara, who was supposedly being chased by a ghost. Investigating, the Doctor found that a Helestican spaceship was hidden in the cellars, and that it had sent Ross forward in time from 2015 and that the ghost was an echo of Ross created by the time travel. After blowing up the school to free the spaceship, the Doctor returned Ross home. (PROSE: Haunted)
Setting up the downfall of Josiah W. Dogbolter, the Doctor froze the villagers of Stockbridge in 2016 "between nanoseconds" to keep them safe, and called for his friends to help him. He had the shape-shifting Whifferdill Frobisher take the form of one the Doctor's old opponents, Chiyoko, to lure Dogbolter into Stockbridge, had Majenta Pryce blackmail the major shareholders of Dogbolter's company, Intra-Venus, Inc., into giving her their shares for a low price, and had Lady Destrii of the Oblivion Empire brought along to defend Majenta against Josiah's daughter, Berakka Dogbolter. Landing in Stockbridge, the Doctor found Maxwell Edison, who was unaffected by the time freeze because of his TARDIS travels.
The Doctor pretended to surrender himself to Dogbolter inside St Justinian's Church, and, revealing his identity, Frobisher incapacitated Dogbolter's henchmen. Izzy Sinclair arrived at the church to knock Dogbolter out, and Sharon Allen broadcast Dogbolter's confession to murdering thousands on the Galactic Broadcasting Corporation. This led to Dogbolter's arrest, the seizing on his assets and Majenta becoming the new CEO of Intra-Venus. The Doctor subsequently returned the villagers to normal. After defeating Dogbolter, the Doctor brought Max and the rest of his friends to the city of Cornucopia to celebrate Max's 60th birthday. (COMIC: The Stockbridge Showdown)
Following an anachronistic transmat signal to an army base in 1944 America, the Doctor found that the base had been infiltrated by the Valbrect, who were planning to invade Earth after replacing all the personnel at the base. While the human soldiers still at the base dealt with Valbrect soldiers, the Doctor saved the kidnapped personnel and threatened the Valbrect into leaving by placing a bridge-buster bomb on the Valbrect mothership. (PROSE: Base of Operations) The Doctor then attended Clara's opening of the Danny Pink IT Suite. (COMIC: Witch Hunt)
The coming of the Hybrid
After the Doctor escaped a marriage to a sentient plant on the "second most beautiful garden in all of time and space", Clara was phoned by Rigsy, who had lost his memory of the previous day and woken up with a chronolock that was counting down to his death. Investigating, the Doctor, Clara and Rigsy found themselves in the Trap Street, where a society of aliens were seeking asylum under the government of Ashildr, known in the street as "Mayor Me". Rigsy had apparently murdered one of the residents, a Janus named Anah, and had been given retcon and returned home to allow him to spend time with his loved ones before the Quantum Shade came to kill him for the crime. When Ashildr informed the Doctor that she could remove the chronolock if he convinced the Trap Street residence of Rigsy's innocence, the Doctor learned from Kabel that Rigsy had asked Ashildr to call the Doctor when he was found with the body, revealing that Ashildr knew of the Doctor and Risgy's acquaintanceship.
Going to see the victim's daughter, Anahson, the Doctor realised that the entire thing had been a trap to lure him to the Trap Street. Running to see the body, the Doctor discovered that Anah was alive in a stasis pod, and the only way to release her was to unlock the pod with his TARDIS key. Unlocking the stasis pod, the Doctor had his arm clamped with a teleport bracelet, just as Ashildr arrived to retrieve the Doctor's confession dial. Just as the chronolock countdown ended, Clara revealed that she had taken Rigsy's death sentence, and Ashildr explained that the entire thing had been a hoax to entice the Doctor, as she had been threatened to entrap the Doctor to ensure the street's safety. Rigsy would have had the chronolock removed before its countdown ended, but since Clara took it, Ashildr fell out of the contract she had established, sealing Clara's fate. In anger, the Doctor threatened to end the asylum unless Ashildr saved Clara, but Clara made the Doctor promise not to seek revenge before she faced her death, with the Doctor watching her die from afar. Ashildr apologised for the harm she had done, but the Doctor, honouring his promise to Clara, warned her to keep out of his way. The teleport bracelet then activated, teleporting the Doctor away to its destination. (TV: Face the Raven)
In a cycle that went on for 4.5 billion years, (TV: Hell Bent) the Doctor arrived in a teleporter at the top of a tower inside his confession dial, and was pursued by the Veil, a clockwork creatue whose form was taken from his childhood nightmares, until he fed it confessions. At the end of each cycle, the Doctor reached a wall of solid azbantium and, inspired by the Brothers Grimm story of the shepherd's boy, punched at the wall until the Veil fatally burned him. Too badly injured to regenerate, the Doctor dragged himself back to the top of the tower and burned up his body to provide the energy needed to load a copy of himself at the moment of his arrival from the teleporter's hard drive, continuing the cycle until he finally broke through the wall. With the Veil collapsing in on itself, the Doctor arrived on Gallifrey and told a nearby boy to inform "someone important" in the Capitol of his arrival. (TV: Heaven Sent)
The Doctor made his way to the Drylands, where he silently waited in his old barn hideaway for Rassilon to face him, turning away the military and High Council members sent to speak to him, until Rassilon finally came to explain himself, to which the Doctor told him to "get off [his] planet." Deeming any witness in the Drylands to be unimportant, Rassilon ordered the Doctor's execution, but the firing squad, having served with the War Doctor during the Last Great Time War, sided against him. When the General defected, Rassilon surrendered and the Doctor, assuming Rassilon's title of Lord President, banished Rassilon from Gallifrey, which had been moved to the end of the universe for protection, blaming him for the horrors of the Time War, to be followed by the High Council.
Going down to the Cloisters, the Doctor met with Ohila, who explained that Rassilon was searching for information on the Hybrid. Meeting with the General and the Sisterhood of Karn in the council chamber, the Doctor informed them that he could protect them from the Hybrid, but he needed Clara Oswald's help to do so. The Doctor and the General went to Extraction chamber 7 to use an extraction chamber to retrieve Clara from before her death in the Trap Street, in doing so freezing her bodily functions in time. Under pressure to explain himself, the Doctor swiped the General's sidearm and, holding the unarmed chamber staff at gunpoint, took a neural block calibrated for humans and shot the General to cause a distraction and escape with Clara.
Making their way through the Cloisters, the Doctor and Clara encountered the Cloister Wraiths, and an imprisoned Dalek, Cyberman and flock of Weeping Angels, until the Doctor found a secret passage near lift shaft 7, and told Clara how he had originally found the passage in his first incarnation, and also tried to avoid talking about his imprisonment in his confession dial, but had got around to telling Clara by the time the newly regenerated General and Ohila arrived. As Clara distracted them, the Doctor escaped through the secret passage into the workshop below the Cloisters, and stole a TARDIS to retrieve Clara and flee from Gallifrey after a final talk with Ohila.
With Clara still frozen, the Doctor took her to the last minutes of the universe, believing that her time would reset and she would become alive again. With Clara still frozen, a knock sounded on the TARDIS doors and the Doctor found it was Ashildr, still alive at the end of the universe. The Doctor and Ashildr shared theories on the Hybrid; the Doctor believing it to be Ashildr, while she believed the Hybrid to be either the Doctor himself, or the combined forces of the Doctor and Clara. The Doctor, denying Ashildr's claims, told her that he planned to erase Clara's memory of him to protect her from the Time Lords, but Clara had spied on their conversation and reversed the polarity of the neural block with the sonic sunglasses. After learning of what Clara did, the Doctor still decided to use the device, only for it to backfire on him, causing him to lose his memories of Clara and collapse.
The Doctor eventually awoke in the Nevada desert, where a man told him that Clara had asked him to look after the Doctor. Having forgotten Clara's face, but still having vague impressions of his time with her, the Doctor made his way to a diner in the desert, where he encountered a waitress. The Doctor told the waitress his story while playing a song he composed for Clara. After his story ended, the waitress exited through a door, and the diner dematerialised, revealing to the Doctor that it had been the stolen TARDIS. Now outside, the Doctor found his own TARDIS, with a mural dedicated to Clara on it, whom the Doctor recognised as the waitress. Receiving a new sonic screwdriver from the TARDIS, and a final message of encouragement from Clara scrawled on one of the TARDIS' blackboards, the Doctor took off for new adventures on his own, with the mural unravelling as he dematerialised. (TV: Hell Bent)
The Doctor received a call from Osgood, asking for his assistance in dealing with the Experimental Prototype Robot K2 that was running amok in 2016 London. The Doctor was able to dismantle K2 with his sonic screwdriver, ending the threat. (COMIC: Robo Rampage)
The Doctor detected temporal tsunamis in the Time Vortex, and realised something was wrong with time and that he needed to get to Gallifrey. As Gallifrey was blocked by a transduction barrier and he was unable to contact the High Council, he travelled to Karn to persuade Ohila to let him use the Sisterhood of Karn's door to the Capitol. Ohila was reluctant, but when Karn was suddenly attacked by Cybermen, she let him through. The Doctor rushed into the Capitol only to find Rassilon, who, after his exile, had met with a league of Cybermen and decided to work with them to create a new Time Lord-Cyberman empire. The Doctor was then rescued by a group of Time Lord soldiers led by the General, who requested the Doctor's assistance in helping them combat the threat. When he experienced pain spasms, the Doctor realised that Rassilon's corruption of the Eye of Harmony was rewriting the Doctor's own history to ensure his previous incarnations were defeated by the Cybermen on their adventures. The Doctor then surrendered to Rassilon to learn more of his plan, which was to siphon the regenerative energy of the Time Lords with Looms to restart the universe in Rassilon's image.
However, the Cybermen betrayed Rassilon and began harvesting his and the Doctor's regeneration energy to fuel the reworking of history, allowing the rise of the "Age of Cyberiad". Having realised his mistake, Rassilon telepathically contacted the Doctor inside the Cyberiad, and the two teamed up to send their regeneration energy backwards through the Eye of Harmony, repairing the alterations made to the Doctor's timeline and the universe and destroying the Cyberiad. The Doctor's previous incarnations and everybody else lost their memories of the incident, with only the Twelfth Doctor remembering. Back in his TARDIS alone, he openly wondered if Rassilon remembered as well to keep a time loop from happening. (COMIC: Supremacy of the Cybermen)
Summoning his tenth incarnation to an uninhabited planet, the Twelfth Doctor, having taken precautions to ensure that his predecessor would remember the important parts of their meeting, informed the Tenth Doctor of Gabby Gonzalez's importance and wrote out the answers in Gallifreyan before sending him on his way, gifting him a piece of chalk. (COMIC: Vortex Butterflies)
The Doctor visited Shivani Bajwa at her flower garden at Coal Hill School, and learnt that Missy had secretly assisted him when his first incarnation fought off the Space wolves with Shivani in 1963. When he saw Missy across the street from him, the Doctor bade his farewells to Shivani has he ran after her. (PROSE: Doctor Who and the Horror of Coal Hill)
The Doctor answered a call for help from Harry Houdini after his old friend had been implicated in a series of deaths. Searching the warehouse of a rival magician named Gladstone, they found find an empty prison pod, but the escaped alien prisoner killed Gladstone and flew away. (PROSE: Who-Dini?)
When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the Twelfth Doctor learnt that Earth was under threat from a pandimensional entity that had trapped his fourth incarnation in his TARDIS. While the Twelfth Doctor argued with his other incarnations, the War Doctor used encoded messages from the Sixth Doctor to stop the invasion before it began, and the Sixth Doctor installed a way to expel the entity from the Fourth Doctor's TARDIS, ending the crisis. (WC: Doctors Assemble!)
Brief travels with Hattie
Catching up on his favourite music, the Doctor visited the Twist, a colony in the 40th century, to attend a punk concert. Meeting with the band's bassist, Hattie Munroe, the Doctor observed a man called Jakob being chased by police, and found out he had been accused of the murder of councillor Idra Panatar after he rescued him, though Jakob insisted his innocence, claiming fox-like creatures on the colony had done the deed, and that the authorities were attempting to cover up other attacks. While investigating Idra's house, the Doctor discovered a secret room in the house containing proof of the creatures, leading him to deduce Idra was killed to keep them from being revealed. They went to the Central Power Park to investigate, and, after avoiding a police chase and an attack by one of the creatures, they escaped into an underground tunnel, which led them to the vessel that first brought humans to the Twist. The area was populated by the creatures, who revealed themselves to be called the Foxkin.
Escaping into a nearby statis farm, the Doctor found pods that contained human remains. Accessing the records, he found that none of the human colonists travelling to the Twist had survived the journey, despite the population apparently having been descended from them. Analyzing the footage more closely, he deduced that Foxkin were evolution of the foxes that had been aboard the colony ship and, taking sympathy on their deceased precursors, had cloned them back to life before he, Hattie and Jakob were imprisoned by the Foxkin to be kept from revealing the truth. Escaping imprisonment, the group returned to the surface, where Jakob declared that the Foxkin had to be destroyed, but the Doctor revealed he had worked out that Jakob had purposefully killed Idra to stop her from revealing the Foxkin, due to his hatred of the creatures and Idra's desire to broker peace. Jakob fled, and was eventually arrested by the authorities. The Doctor and Hattie held a concert to encourage the humans of the Twist to accept and welcome the Foxkin into their society. In the aftermath, the Doctor invited Hattie for a trip in the TARDIS. (COMIC: The Twist)
While the Doctor and Hattie were having a jamming session, the TARDIS made an emergency landing to a house on windswept moors, attracted by dangerous radiation levels. As the Doctor and Hattie investigated the house, Hattie caught a glimpse of a holographic young girl. Following the hologram through a door, the Doctor and Hattie entered a forest, where they found a mother, Holly, searching for her family. Holly told them that the house, which was her own, had grown new rooms since she purchased furniture at an antique fair. The Doctor discovered that void creatures known as the Spyrillites were being attracted to the house as it had a great source of arton energy. Letting the Spyrillites guide him, he found a room containing an architectural reconfiguration system, and he realised the house was actually a TARDIS.
The Doctor determined that an item Holly brought at the antiques fair was a TARDIS shell, which was dying and leaking arton energy, causing its dimensions to spill into the house and potentially across the whole universe. After finding Holly's family, they were directed to the control room of the TARDIS. Hattie and her family fought off an attack from the Spyrillites as the Doctor programmed the TARDIS to send it to die in the heart of a star, restoring the house to normal. After another jamming session aboard his TARDIS, the Doctor returned Hattie back to her home on the Twist. (COMIC: Playing House)
Living with the Collins family
Wanting to visit a music performance in 1972 London, the Doctor was playing his guitar on the streets when he was sighted by Jess Collins, who followed him to the TARDIS, despite his attempts to avoid her. When the TARDIS picked up an alien distress signal in the London Underground, where Jess' father, Lloyd, worked, Jess followed him to investigate the signal. In the tunnels, they were caught by Lloyd and then attacked by a skeletal bird creature, but the Doctor disabled the creature with electricity from the Underground, noting it was an animated cadaver. Lloyd, injured by the creature, was taken to hospital, where the Doctor scanned him and realised he had an unidentifiable bacterial infection. Returning to the Underground with Jess, the Doctor found a telepathic node on the creature's body, which explained that the creature was an alien called Moan'na, who had fled his kind and disguised himself as a human in 17th century London. The Doctor determined that Moan'na had died of the bubonic plague as a human in 1665, but his alien body had enhanced the illness and caused Lloyd to fall under it.
The Doctor and Jess returned to the hospital and found Lloyd had mutated into a creature like Moan'na, who knocked the Doctor out and took Jess away. Upon awakening, the Doctor and Jess' mother, Devina, pursued them to Brixton, as the infection began mutating more people. The Doctor used the telepathic node to allow Jess and Devina to communicate with Lloyd and break the infection's control over his mind, which, in conjunction with the TARDIS' telepathic circuits, rewrote the DNA infections to change Lloyd and the infected back to normal. However, the the TARDIS' systems overloaded and caused it to retreat within itself. The Collins family invited the Doctor to stay with them while the TARDIS recovered. (COMIC: The Pestilent Heart)
The Doctor dismantled the TARDIS' outer plasmic shell and put it back together in the Collins' back garden, where he left it to heal. While explaining to Lloyd what had happened when he was infected, the Doctor was caught off guard by the housecat Tibbsy, and warned Tibbsy that he would be watching him. The next day, the Doctor ruined Devina's fish stew when he used his sonic screwdriver on it, but prepared his own stew for the family himself, and cleaned up the kitchen, with the Collins family impressed with his cooking.
Two days later, while trying to encourage the reweaving of the TARDIS' shell, the Doctor debated with Jess' bother, Maxwell, over who would win in a fight between Batman and Captain America, with the Doctor choosing Captain America and debating his choice with Maxwell afterwards. Later, while Jess was reading M. C. Escher for her art history class, the Doctor recounted the times he met Claude Monet, Pierre-Auguste Renoir, and François Boucher, and when he had his portrait done by the cubist artist Pablo Picasso. While trying to lighten Jess' book with his sonic screwdriver, but it ran out of power, and the Doctor was unable to use the TARDIS to recharge it. With no TARDIS to leave 1972 in, the Doctor instead offered to show Jess the universe through the art she was studying. (COMIC: Moving In)
The Doctor took Jess and Maxwell to the National Gallery to show them a John Constable painting, when an alien creature was released by hunters from Kolothos, where hunting was outlawed, who sent hounds to chase it into the gallery. The Doctor, Jess and Maxwell followed the creature outside into Trafalgar Square, and witnessed the hunter Skadi murder a policeman. The Doctor used a dog whistle to incapacitate the hounds, and when Skadi's husband, Broteas, killed another policeman, the Doctor knocked him out by pulling his electric whip into a fountain. Skadi murdered the small creature she was hunting, and she and her son, Tarquel, took Jess and Maxwell aboard their spaceship.
Left behind on Earth, Broteas was taken to Scotland Yard by DCI Jack Hayes on a murder charge, and the Doctor gave him food in exchange for Skadi's comms frequency. He offered himself and Broteas to Skadi in exchange for her releasing Jess, Maxwell, and the spaceship's menagerie, which Skadi was using to release rare and exotic creatures onto alien worlds so they could be hunted for fun, and then leaving Earth. Skadi sent her hounds after the Doctor in Epping Forest, but the Doctor used a reprogrammed metal horse belonging to Broteas to knock the hounds over. Maxwell tricked Skadi into dropping her sword and having Hayes arrest her when she threatened Tarquel. However, this was part of a ruse to have Tarquel take his parents home to face justice for all of the killing they had done. The Doctor convinced Hayes that Skadi and Broteas facing their own people's justice would be worse off than being tried on Earth, and he let them leave Earth with Tarquel. (COMIC: Bloodsport)
While Jess and the Doctor were delivering Christmas cards on 23 December, they saw Walter from across the street behaving oddly and then slamming the door. The Doctor kept an eye on Walter's house all night. The following day, the Doctor saw Walter throw a Snowglobe through his window, and went with Jess and Devina help him. The Doctor defeated the fictional character Obadiah Grimm that had been created from Walter being left alone for too long with the guilt of losing his mother, Carmen, in 1971, and Walter was taken away in an ambulance to treat his mental illness. On Christmas morning, Devina invited the whole street for breakfast as a reminder that the street was a community and to remember Carmen. (COMIC: Be Forgot)
During a game of chess with Gabriel Gayle, the Doctor was invited by DCI Hayes to Scotland Yard to help with a case involving a man who had been turned into glass. Hayes and Officer Perkins took the Doctor to the warehouse in Barking where the man had been found, where a giant mosquito attacked and turned Perkins into glass. Though the Doctor and Hayes managed to electrocute the mosquito with a generator, more mosquitoes attacked the warehouse, but the Doctor drew the mosquitoes towards Hayes' car, where they trapped their stingers in the car roof and the Doctor rigged the car to explode, killing the mosquitoes.
Returning to Brixton, the Doctor realised that the events in Barking were a distraction for someone to steal the TARDIS, and also discovered the shrunken body of Gabriel Gayle in the Collins family garden, alerting the Doctor to the presence of the Master, just as he and Hayes were escorted to meet him by Katya Dabrowski. The Master murdered Hayes when he tried to arrest him, and told the Doctor the Collins family were running errands for him when he used the artron energy in their bodies to open a portal to a time locked dimension. The Master linked the Doctor's TARDIS to his TARDIS to aid the Doctor through the time lock so he could be reunited with the Collins family, Katya accompanying the Doctor in his mission.
Followed by the Master into the Time Locked dimension, the Doctor met Kiadine, a being the Time Lords imprisoned for ravaging his world by splitting the chronon. Kiadine gave his life and his temporal powers to the Master to gain his vengeance on the Time Lords. After the Master aged Katya to death, the Doctor and the Master fought with each other over the power of the chronon storm, when the Collins family pulled the Doctor back, standing together against the Master. The Master attacked them, but his blast was repelled with the same artron energy in the bodies of the Collins family that had brought the Master to the dimension. The Master, heavily wounded by the attack, retreated, and, with no-one left to keep time in check, the Doctor and the Collins family evacuated. After Gabriel's funeral, the Doctor said goodbye to the Collins family and left, believing he had outstayed his welcome. (COMIC: Doorway to Hell)
A return to travelling
The Doctor visited the planet Lahn to travel the Spice Route of Shalabar Stone. However, his party was ambushed by alien scavengers led by the Lord Boabdil, who kidnapped the Doctor's fellow traveller, Estrella, sentencing her to be executed the following day by a monster. The Doctor gatecrashed the execution and disorientated the monster, freeing Estrella. Chased into the city, Estrella bought a flying carpet, allowing her and the Doctor to escape their pursuers. (COMIC: The Spice Route)
The Doctor found that the Flying Dutchman was making appearances throughout history, and tracked it through time. On a sighting on the seas in 1881 Australia, he was joined by Prince George and Captain Thorpe after they wandered into the TARDIS. The Doctor deduced mathematically that the ship would appear during the Battle of Trafalgar, and he, George and Thorpe managed to board it, only to be confronted by robots claiming to be the ship's crew. After George meddled with the ship's machinery, the robots lost their memory. The Doctor found that the robots had crashed their time ship into the Flying Dutchman and that had caused them to believe they were the crew. The Doctor repaired the ship to send the robots home, and also prepared to return George and Thorpe to their own time as well. (COMIC: Ghosts of the Seas)
Surrounded by robots in the Forbidden Zone, the Doctor had his life saved by Lambert. Lambert and his son, Kiron, declined to travel with the Doctor as the Forbidden Zone was still their home, so the Doctor instead promised to help Kiron every time he was in danger by installing a low-level telepathic link to his wrist device. (COMIC: The Promise) He then went and possessed for The Hay Wain painting. (COMIC: Doorway to Hell)
Attending a book festival, the Doctor learnt of a book series called Fearsome Frights by an author named Charles Abbott. After a girl named Eliza told him that the protagonist of the book shared the name of her brother Sammy, who had disappeared after meeting Abbott at a signing, the Doctor and Eliza tracked the book in the TARDIS, and the Doctor deduced that Abbott was a disguised alien who used a pen made of Incredulitas 4 that could transport matter. They arrived on the planet Antagonista, the setting of the book, and rescued Sammy from zombies. Abbott arrived and tried to attack the group with his pen, but the Doctor used his sonic screwdriver to counter the attack and trap Abbott in a stasis jail cell in space. Dubbing the cell the "writer's block", the Doctor returned Eliza and Sammy home. (COMIC: Shock Horror)
The Doctor then visited what he thought was the English countryside for a breath of fresh air, but after almost walking off the side of a floating island, he discovered that he was on New Belgravia. He met the owner of the island, Lord Eskdale, who asked the Doctor to help him find his missing daughter, Charlotte. Shortly after the Doctor accepted the offer, the floating island began to fall towards the ground. In the engine room of the island, the Doctor found Charlotte, who had hid there after seeing her father discriminate against the planet's natives. Eskdale apologised to his daughter, leading to her letting the Doctor into the engine room. He moved the island back into the sky, saving countless lives. (COMIC: Sky Manor)
After he rescued Kiron from a Howler, (COMIC: The Promise) and needing some time to relax alone, the Doctor visited Eed'n to take photos of the native flora and fauna. After taking a few pictures, he disappointingly discovered that Jain Relph, a professor from the Mega Galactic University, was also on the uninhabited planet cataloguing plant life. As the Doctor began to tell Relph to go away, the two were attacked by spores from Eed'n's plant life and were possessed by an entity called the Plant. The Plant realised that it could go to the beginning of the Universe with the Doctor's TARDIS and seed itself into all lifeforms. However, due to the Doctor having multiple personalities, the Plant had difficulty in completely absorbing him. The Doctor used the little control he had not to pilot the TARDIS to the beginning of time, but to the end, where the Plant died due to lack of sunlight. The Doctor then dropped off Relph at a nearby human colony. (COMIC: Petals)
The Doctor then went to 1909 Paris, where he attended the grand reopening of the Galerie d'Art de Parisiennes, and discovered an alien which was taking people into paintings and attempting to drain their lives. The alien attacked the Doctor and pulled him into Bridge over a Pond of Water Lilies, and chased him through multiple paintings until he discovered over victims of the alien. Using a pen, the Doctor drew a door out of the painting world and back into reality and threw a can of white paint at the painting which the alien was hiding in, trapping it in the canvas. (COMIC: Gallery)
The Doctor learned that the Earth Empire trading planet Vourakis 3 was being blockaded and travelled to the planet to stop the blockade before it caused an inter-planetary war. He encountered reporter Heddy Garber and took her onto the ship responsible for the blockade in his TARDIS. They discovered that colony governor Ron Cordell hired a group of Skinks to blockade the planet and were taken prisoner by the Skinks, who tried to drop the Doctor and Garber into their ship's black hole drive, but the Doctor used his sonic sunglasses to sabotage the drive, and it began to destroy the Skink ship. The Doctor and Garber ran back to the TARDIS and escaped just before the entire ship was sucked into a black hole. With Vourakis 3 saved, the Doctor dropped Garber off in Piccadilly Circus before heading off into another adventure. (COMIC: Pirates of Vourakis)
The Doctor visited the planet Rhodia, whose population of three billion was being wiped out by the Shadow Kin, who had emerged during the civil war that was being waged between Rhodia's two factions. He was only able to rescue the Rhodian prince, and the Quill terrorist who was forced to protect him as punishment for her crimes. For their protection, the Doctor relocated the pair to Shoreditch on Earth, where the Quill would serve as a teacher at Coal Hill Academy, with the prince attending her classes as a sixth form student named "Charlie Smith". (TV: For Tonight We Might Die)
The Doctor was invited to Kiron's chambers when he became President. He discovered that every time Kiron was saved, videos of him being protected went viral and he grew in power. Kiron amplified the link to control the population of the entire planet to rebuild the city and enslave their enemies. When the Doctor withdrew his protection of Kiron, the spell was broken. Realising he had done wrong, Kiron asked the Doctor to help set things right. (COMIC: The Promise)
When the Shadow Kin caught up with Charlie and Quill at the Coal Hill Academy autumn prom night, Quill called the Doctor for help, and he returned to Coal Hill. Confronting the king of the Shadow Kin, Corakinus, the Doctor used their aversion towards light to repel them, forcing them back through the tear in space time from which they came before sealing it. Knowing that such tears would continue to threaten the school as a result of the excess artron energy in the area, the Doctor entrusted Quill and Charlie to defend against whatever would come through alongside Charlie's fellow students who had faced the Shadow King alongside him. Before leaving, the Doctor took Ram Singh, a student who had been maimed by Corakinus, aboard the TARDIS to fit him with a Lothan prosthetic limb to replace his severed leg. (TV: For Tonight We Might Die)
Returning Jata home
The Doctor tracked a crashed Q7 starship to the Wyoming desert in 1899 and encountered the bounty hunter Molly Zook, who was tracking the big-time criminal Clint Currie. She showed the Doctor wanted posters of Currie and his horse, which the Doctor recognised as an Osumaran masquerading as a horse. After buying a horse and painting a star on its forehead so it resembled an Osumaran, the Doctor went to where Currie's gang had tied up their horses and replaced the Osumaran with the real horse. Without the Osumaran to guide him, Currie was caught and arrested by the town's sheriff. The Doctor asked to keep Currie's horse as a reward for helping with the capture. The Osumaran introduced himself as Jata and thanked the Doctor for rescuing him, but the Doctor told Jata that his starship was too broken to work again and decided to take Jata back to Osumare in the TARDIS. (COMIC: From the Horse's Mouth)
During the trip to Osumare, Jata mentioned he was interested in educational systems, which prompted the Doctor to show him an English school in the 21st century. Much to the Doctor's surprise, the school they landed in was filled with students put into a violent trance by their ear buds. The Doctor and Jata hid in the school's chapel with three teachers and a student. The Doctor knew about a secret room in the chapel and guided the student, Jata, and one of the teachers to it when the mind-controlled students broke through the chapel's doors. In the hidden room, the Doctor realised that the student was a Mkali. He confronted the Mkali and asked him to reverse what he had done to the other students. When that didn't work, the Doctor called the Mkali's mother, who became very angry at her son and fixed everything he did. (COMIC: Fear Buds)
After seeing an opera in 1695 Paris, the Doctor was confronted by Julie d'Aubigny after the show when he refused to take part in the standing ovation, with the Doctor escalating the situation by insulting her singing and having Julie challenge him to a sword duel. The duel was interrupted by Cardinal Richelieu, who wanted to question the Doctor, but was stabbed by Julie and exposed as being possessed by dark forces. The Doctor fled to the TARDIS and took Julie with him, knowing that there were mysterious forces at work. The Doctor and Julie went to the Bibliotheque Mazarine library to find information on the forces, with the Doctor using his psychic paper to get the library's curator, Bishop Mazarin, to tell him that Richelieu had created an intelligence network called the Cabinet Noir to intercept the mail of Paris and instructed Mazarin to build a secret library to store confiscated mail, and that Richelieu had experimented with magic and opened a realm of beings, which granted him the ability to not age. Mazarin gave the Doctor the keys to the secret library and told him that Richelieu was plotting to create another portal to plunge the entire world into darkness, but he was suddenly killed by gargoyles before he could say anymore. The gargoyles attacked the Doctor, but Julie managed to destroy the head of one, revealing them to be robots, as the Doctor looked at a chart in the secret library and found an astrological prediction that predicted an eclipse, which the darkness planned to use for their invasion.
The Doctor and Julie escaped the library as the gargoyles burnt it and went to warn King Louis XIV of the plan, only to find he was already possessed by Richelieu and the darkness. Julie was separated from the Doctor and imprisoned to be executed during the king's festival, but the Doctor freed Julie by posing as her executioner. The eclipse began, and the darkness started to emerge and attack. The Doctor used the sonic screwdriver and TARDIS to open a portal into the Ssabrehagen Quaser to spread light across the land, destroying Richelieu and the darkness. Julie asked the Doctor if she could join him in the TARDIS, but he declined. The two instead decided to finish their sword duel. (COMIC: Terror of the Cabinet Noir)
After picking up Dorium Maldovar to use as a ball, the Doctor went to a forested planet to play a game of bowling with Strax, using robotic dinosaurs as pins. Strax arrived on the Time Shark and used himself as a bowling ball. He broke all of the dinosaurs, making it impossible for the game to continue. Afterwards, the Doctor took Strax and the Time Shark with him in the TARDIS to help save the universe. However, instead of helping him, Strax and the Time Shark explored the TARDIS and tried on clothing in the TARDIS wardrobe. (COMIC: The Adventures of Strax & the Time Shark)
The Doctor arrived on board a high-paying ship, stuffed with aristocrats from various species, which attempted to discover and excavate a lost city hidden below the waves of New Oceana. The team eventually arrived to the doors of the Saffshran Ziggurat, which had been sealed for almost a thousand years, and was greeted by an awoken army of Quarks, who swiftly attacked the group. Realising that the Ziggurat was a Quark Manufactorum, the Doctor flooded the city as the team escaped using their breathing devices. (COMIC: Beneath the Waves)
The Doctor chased Missy across Earth in different times and places as she stole numerous valuables, from the British Crown Jewels to diamond rings. The Doctor retraced his steps and discovered Missy had left Cybermats as she went. Missy was disappointed that the Doctor had foiled her plan despite not even knowing what the plan was. The Doctor then went off in his TARDIS to have lunch, not even bothering to let Missy explain her plan to him. (PROSE: Dr. Twelfth)
The Doctor went to New York City in the 1990s to undo the damage from the temporal paradoxes he had played a hand in. While setting up a trap to prevent anyone from interfering with his work, he fell victim to it himself and had to be rescued by Grant, a child obsessed with comics who nicknamed him "Doctor Mysterio", a name the Doctor immediately took a liking to. The Doctor decided to have Grant help him, handing him the Hazandra needed to power his device. However, Grant mistook it for cold medicine he needed and swallowed the gem. As the Hazandra granted wishes, it gave Grant superpowers, as he wanted to help people. The Doctor made Grant promise to never use his powers, so he wouldn't become corrupted by them. He kept an eye on Grant during his later years. (TV: The Return of Doctor Mysterio)
The Doctor ventured to Catrigan Nova to warn Queen Lydia that her prized gauntlet was part of a Cyberman, but arrived too late to prevent her upgrading her guards and castle, linking her kingdom to the Cyberiad hive mind. Lydia initially imprisoned the Doctor for trying to take the gauntlet from her, but eventually came to listen to him after her daughter, Mida, was unintentionally upgraded by her touch. The Doctor instructed Lydia to lead her fully-converted citizens to the gilded whirlpools of Catrigan Nova, with the nuggets of gold within the pools wearing away the Cybermen into nothingness. Lydia then destroyed the gauntlet, freeing Mida from the Cyberiad. (PROSE: The Mondas Touch)
Reunion with River
Relaxing in his TARDIS after a "long day" that had involved "everybody turn[ing] into lizards" and a piano falling on him, the Doctor was mistakenly summoned by Nardole for a "medical emergency" on Mendorax Dellora and brought to River Song, who failed to recognise the Doctor due to not knowing about his new regeneration cycle, as her "husband", King Hydroflax, needed a lifesaving operation to remove the Halassi Androvar diamond from his head. However, River intended to remove Hydroflax's head, and managed to steal it when Hydroflax, whose head was dispensable, discovered the ruse and tried to kill her and the Doctor, until the Doctor took his head hostage and, with the robotic body unwilling to potentially harm Hydroflax's head, the Doctor and River managed to get teleported out by Ramone, another of River's "husbands".
Arriving back at the TARDIS, the Doctor and River, still not knowing his identity, "stole" the TARDIS to get away from Hydroflax's body, but the TARDIS could not dematerialise with the head inside and the body outside, and River was tricked into letting the body in after it stole Nardole and Ramone's heads. Escaping the body on the Harmony and Redemption, River tried to sell the diamond to Scratch of the Shoal of the Winter Harmony, only to learn that he was a follower of Hydroflax, and the two attempted to leave with Hydroflax's head. However, Hydroflax's robotic body arrived and killed the head, having been promised the Doctor's head as a replacement. To the Doctor's sorrow, he listened to River as she showed a lack of belief in his love for her, saying that while she loved him, he didn't fall in love with people. As the Doctor revealed who he was to River, River told the Doctor she was "just keeping them talking". As a meteor storm hit the ship, the Doctor defeated Hydroflax's body by tricking it into using the universal banking device and he River attempted to stop the Harmony and Redemption from crashing on Darillium. They ultimately failed, barely shielding themselves in the TARDIS instead during the impact.
Regaining consciousness first, the Doctor emerged from the TARDIS on Darillium, and, using the diamond, inspired a man named Alphonse to start a restaurant, so he could travel into the future and book a reservation for a balcony view of the Singing Towers. Dressing formally for River when she awakened, the Doctor gifted her with a sonic screwdriver of her own, and, telling her that nights on Darillium lasted twenty-four years, the two enjoyed the view. (TV: The Husbands of River Song) True to his word, the Doctor stayed with River on Darillium for twenty-four years. During this time, the Doctor, worried he would be lonely when the night was over, recovered Nardole from Hydroflax's body (TV: The Return of Doctor Mysterio) and rebuilt him, using human parts in some places. (TV: The Pyramid at the End of the World)
Guarding the Vault
After leaving Darillium, the Doctor was summoned by an unnamed species to an unnamed planet to act as Missy's executioner. However, after Nardole arrived to deliver a message from River Song, the Doctor decided to spare Missy, but still made an oath to watch over her while she was locked up in a Quantum Fold Chamber for a thousand years. (TV: Extremis)
The Doctor and Nardole learned that Shoal of the Winter Harmony had invaded the capital cities of Earth. Inside their company's building in New York City, the Doctor began working to stop their plan of implanting themselves in the heads of the world leaders, which led him to meet up with Grant, who was now the heroic vigilante known as "the Ghost". Together, along with Lucy Fletcher, they stopped Harmony Shoal by destroying their nuclear spaceship before it could be dropped on New York City and decimate Earth. (TV: The Return of Doctor Mysterio)
The Doctor and Nardole eventually took the vault to St Luke's University (TV: The Pilot) during the 1940s. (AUDIO: Regeneration Impossible) As a result of his promise, the Doctor was prevented from "going off-world unless it [was] an emergency", (TV: Smile) and became a lecturer at the university, (TV: The Pilot) being labelled a "Lecturer in Almost Everything", (PROSE: Girl Power!) and given a professoriate. (AUDIO: Regeneration Impossible) Nardole remained with him to ensure he stuck to his "oath", (TV: Smile) as the Doctor had instructed him to. (TV: Oxygen) Missy would occasionally ask Nardole to order items for her, and the Doctor would have to approve her requests. (PROSE: Girl Power!)
Adventures from St Luke's University
When Missy created a Spacebook group chat with some of history's most famous women, particularly from Tudor England, the Doctor thought that Missy was trying to influence history to prevent St Luke's University from being constructed, allowing her to escape the Vault. However, after the Doctor had disbanded the group by infiltrating the chat and deconstructing Missy's leadership, Missy claimed she had only wanted to help the women fight male oppression, leading the Doctor to believe that her rehabilitation was beginning to take effect. (PROSE: Girl Power!)
Following a clue of a missing student to a morgue in 1892 London, the Doctor was trapped in an Assassination Box and forced to undergo multiple false regenerations. When the regeneration energy alerted the Eleventh Doctor to his presence, they discovered that a regeneration vampire had trapped the Twelfth Doctor to drain his regenerations. The Eleventh Doctor was able to return the Twelfth Doctor's regenerations by overloading the Assassination Box, killing the vampire. As his past incarnation was knocked unconscious with his memories of the night erased, the Twelfth Doctor returned him to his TARDIS before taking his own leave. (AUDIO: Regeneration Impossible)
By 2016, (TV: Knock Knock) the Doctor recognised that a canteen worker named Bill Potts was attending his lectures and, admiring her fascination in the unknown, enrolled her in the school as her personal tutor. Bill would meet with the Doctor every day at 6pm for private lessons and kept up a continuously solid grade rate throughout the academic year. As a show of gratitude, Bill gave the Doctor a rug for Christmas, and he returned the gesture by travelling back in time to take photos of her deceased mother.
Sometime into the second term, Bill told the Doctor about a puddle that one of her new acquaintances, Heather, had showed her before she disappeared. Examining the puddle, the Doctor and Bill discovered that the puddle was imitating their movements instead of reflecting their image. Later that night, the Heather-imitating-puddle followed Bill to the Doctor's office and the Doctor, after ensuring the puddle was not after the contents of the Vault, took Bill and Nardole into the TARDIS and lead the puddle to Australia, a planet at the other end of the universe in the future, and then a war zone in the Dalek-Movellan War. While Nardole quarantined the area off, the Doctor discovered that the puddle didn't mean them harm, but was following Bill because Heather had promised not to leave without her before the puddle had absorbed her. Bill released Heather from her promise and the puddle departed. The Doctor and Nardole then took Bill back to the University, with the Doctor planning to "mindwipe" her, but he relented when she asked him how he would feel if it was done to him, and he instead told her to leave. After arguing with himself, the Doctor decided to ask Bill to travel with him and took the TARDIS outside the university to welcome her aboard. (TV: The Pilot)
After fending off Nardole, the Doctor took Bill to visit a human colony in the far future, but grew suspicious when he found no humans in the facility, only the Vardy microbots that had constructed the colony and the their interface, the Emojibots. When the Doctor discovered the Vardy had killed the set-up team, he and Bill escaped the colony, but then ran back in to attempt to destroy the base for the safety of the coming settlers. As soon as the Doctor had wired the ship the city had been built around to explode, Bill showed him that the colonists had already arrived in hibernation waiting for the ship to wake them up, and entering the ship had awakened them prematurely. The Doctor stopped the bomb, and the pair deduced that the Vardy had been built to sustain happiness and had come to view grief as a plague.
The colonists, seeking revenge for their deceased relatives, opened fire on the Emojibots, which prompted the Vardy to attack. Realising that the Vardy had gained sentience, the Doctor rebooted the Vardy, erasing their memories of the humans, before beginning diplomatic negotiations between the humans and Vardy for a peaceful co-existence. Having achieved peace, the Doctor tried to return the TARDIS to the university just after they left, (TV: Smile) but instead landed during the frost fair of 1814.
Deciding to explore the fair, the Doctor and Bill noticed green glowing lights under the ice, but were approached by a street urchin named Kitty before they could investigate. However, Kitty was distracting them from another urchin, who stole the Doctor's sonic screwdriver, but was sucked under the ice in the resulting chase. Unable to save the boy, the Doctor and Bill convinced Kitty to take them to her gang of urchins, and learned that they were getting paid to lead people onto the ice. The Doctor decided to venture under the ice with Bill to see what was in the Thames, and found a large fish-like creature chained down to the riverbed. Investigating the nearby river dredgers, the Doctor learned that the creature's waste was being dug up as a supplement for coal on Lord Sutcliffe's orders.
Captured by Sutcliffe's men after the Doctor assaulted him for his racism towards Bill, Sutcliffe revealed that his family had known about the sea creature for years and the fuel it provided was accelerating industrialism. Sutcliffe had the Doctor and Bill tied up near a dynamite-laced-tent, but they were able to escape. Leaving Bill and the urchins to clear the River of people, the Doctor moved the explosives towards the creature's chains, freeing it when Sutcliffe activated the dynamite. As the ice shattered from the creature's escape, killing Sutcliffe, the Doctor rescued Bill by pulling her off of the ice before they got soaked as the sea creature passed them by. After amending Sutcliffe's will to name one of the urchins as his heir, the Doctor and Bill returned to the university, where the Doctor used a coin trick he had learned to convince Nardole to let him continue travelling with Bill. (TV: Thin Ice) The Doctor and Bill would meet up for adventures on Saturdays. (TV: World Enough and Time)
Early adventures with Bill
After Bill asked him to help her move into a student house, the Doctor grew suspicious of the fact that an old, large house was being rented to Bill and five other students for so little. Bill and the Doctor discovered that the Landlord was using strange insects to keep his mother alive in a wooden form by feeding people to them every twenty years; convincing the mother that her son was wrong to keep her alive this way, the Doctor was able to free the house's recent victims, while the Landlord and his mother were consumed by the insects and the house collapsed. (TV: Knock Knock)
The Doctor continued adventuring on his own on occasion, notably evading a ring of tanks and a murderous Black Dalek through cleverness; he also travelled to a city that was about to be destroyed by an exploding volcano, all to rescue a single bird left behind in its cage, whom he then released from a mountain's peak in the presence of Bill. (WC: A Hero like the Doctor)
Threats from the Dreamspace
Landing on Titan to get a good view of Bill's favourite planet, Saturn, the Doctor and Bill were swept up in the trail of a land-cruiser studying the surrounding continent of Xanadu. Discovering that the vessel was being funded by Rudy Zoom and was inspired by a vision held by the psychic Lady Takashi, the Doctor and Bill joined the crew in exploring Titan. After several hours, they found a dome hiding a garden inside a cavern, perfectly supported with no animal life. Travelling to the centre of the ecosystem, the Doctor discovered two dead trees. When they were attacked by a robot which saw them as weeds, the group scattered and Bill and the Doctor were separated. Just as soon as the Doctor had deactivated the robot, the plants around them came alive and formed their own bodies, interested in consuming the flesh-based beings around them.
The Haluu plants wrapped themselves around the humans, but the Doctor was able to free himself and Lady Takashi by reactivating the robot and using it against them. The Haluu progenitor Sythorr raised itself out of the ground and ate most of the human expedition. Sythorr intended to wipe Rudy and Bill's memories and use them to take his seeds with them so he can spread his influence across Earth and take it over. The Doctor explained to Sythorr's lover, Oksanna, that Sythorr had placed the minds of dead humans he claimed in the Dreamspace inside the garden's Haluu. Oksanna remembered her life as a human and sacrificed herself to destroy Sythorr along with the domed garden. As the Doctor, Bill, Rudy and Lady Takashi escaped to the ship, the last piece of Sythorr warned the Doctor before dying that "the unknown soldier [was] stirring." (COMIC: The Soul Garden)
The Doctor and Bill landed in the Indian Territory of 1880, where the outlaw Seth Shelton tried to hold Bill hostage, but she was saved by United States Deputy Marshal Bass Reeves and the scout Joey Two Trees, who had Shelton arrested and intended to take him back to Arkansas to stand trial. Joey showed the Doctor and Reeves that a stag had had its heart ripped out of its body, and they then saw a group of Stikini carry Bill away to a ceremony being performed by the Seminole medicine woman Totika. The Doctor and Reeves freed Bill from her capture, but the ceremony caused her to swap her body with the Stikini Cocheta in the Red Skies, another area in the Dreamspace which the Stikini were native to. The Doctor incapacitated Cocheta using the noise of his sonic screwdriver, and contacted Bill in the Dreamspace. Bill and the Seminole banished there by Totika willed themselves out of the Red Skies, forcing the Stikini back there, and Reeves and Joey destroyed the totem used in Totika's ceremonies. Afterwards, the sky opened up, and the group saw the Stikini get burnt by an unknown force in the Red Skies. Returning to the TARDIS, the Doctor and Bill saw the TARDIS had impossible carvings on its exterior. (COMIC: The Parliament of Fear)
Searching for answers, the Doctor and Bill went to the Renath Archive library on Cornucopia to try to identify it, but the Doctor failed to identity any relevant symbol after going through all of the books in the archive. When the head librarian, Matildus Galathea, showed signs of a weakening mind, she asked her granddaughter, Sashana, to be handed custody of the archive, with the Doctor as witness. Before custody could be handed over, Bill, joined by the Kaballus Kids, told them to stop. Bill took a photograph on her phone which revealed Sashana's true form, and Sashana revealed that Matildus had no granddaughter, that she was psychically sowing doubt in Matildus' mind and was blocking her memories so she could sell off the library's collection. Sashana began to fry the group's brains with her mind, but was stopped after Bill summoned the Ristallian crater-hound Archie, whose simple brain couldn't be kept back. After Sashana was arrested, the Doctor realised the carving wasn't a symbol, but a coded message, and decided to visit Alan Turing. (COMIC: Matildus)
The Doctor and Bill went to visit the Galatean duplicate of Alan Turing on the lunar colony Athenia to decipher the markings on the TARDIS, only to learn that Alan had been missing for two years. When Chiyoko told the Doctor where to find Alan, they found him inside a replica of King's College, Cambridge on the Moon's surface, and learned that the code on the TARDIS was part of the Dreamspace-residing Phantom Piper, who tricked the Doctor into coming to Alan so that Alan's Block Transfer Computation could make the Piper take physical form. At the Doctor's suggestion, Alan defeated the Piper and prevented the Piper's plot to start war between humans and Galateans by tricking him into shooting a bullet at a mathematical construct of Alan, which allowed Alan to break down the code of the bullet, which was part of the Piper. Afterwards, Fey Truscott-Sade arrived to warn the Doctor about "the Absence" and told him to assemble his forces. (COMIC: The Phantom Piper)
Following Fey, the Doctor and Bill ended up in an entropy bubble that began draining the power from the TARDIS. Exploring where they landed, they found that many other time travellers, such as Count Jodafra and Gol Clutha and her mercenaries, were also trapped. During an attack by the Clockwise Men, the Doctor used Jodafra's time machine, the Salvation, to power up the TARDIS and escape, but only after Fey reappeared, leading Jodafra to his death at the hands of the Clockwise Men. Returning to Cornucopia, the Doctor met back up with Annabel Lake to enlist help from Wonderland to find out more about Fey's change in behaviour. After escaping a mid-air attack by Fey, they made it to Wonderland HQ, where the Doctor explained to everyone how Fey had apparently died attempting to rescue a Loshann child during the Last Great Time War.
Returning to Matildus, the Doctor used a copy of Peter Pan to access Fey in the Dreamspace, where she explained about her survival and her plans to attack the Time Lords, with the help of an entire map of the space/time vortex gained by the Absence, who appeared as the fully matured Loshann child. Learning Fey's only surviving relative, Alexander Truscott, was involved, the Doctor and Bill went to 2018 London to find him. Upon locating him, Truscott explained his history of altering Fey's mind to make her hate the Time Lords, but was interrupted by the Doctor's "cavalry" of General Kenossium, Marshal Reeves, and Totika. They fled as Fey and the Clockwise Men prepared their attack, only to discover that Shayde was reforming himself as a black sphere around Fey.
Entering the sphere, the group entered the Dreamspace, where the Doctor showed Fey that she had never saved the Loshann child and the Absence had never existed. With her illusion broken, the area of the Dreamspace shattered and Shayde wiped Fey’s mind of her time with him at the cost of his own life. The Doctor dropped Fey off at Wonderland in London and left, neglecting to say goodbye due to his intention to one day see her again. (COMIC: The Clockwise War)
More adventures with Bill
While he was "correcting" the history books in the Terrance Dicks Library, the Doctor received a phone call from Jenny before her bowship crashed into the library. Happily greeting his daughter, the Doctor brought her to his office, where she told him that she had been trying to save Jack Harkness and Tara Mishra from a white hole on Sultath, only for herself to be saved by the Fifth Doctor, and him, Jack and Tara being swallowed by the singularity. When the same white energy that Jenny had described attacked St Luke's University, the Doctor realised that time travellers were not affected by the energy and tried to enter the TARDIS, only to find that it had merged with that of his tenth incarnation. Strategising with his predecessor, the Doctors and Jenny ejected themselves from the TARDIS, only to be surrounded by a mob of possessed students, but they were saved by the Ninth Doctor as a massive white hole opened in the sky.
Joined by Bill, Nardole, Gabby Gonzalez and Cindy Wu, the three Doctors ran into the Ninth Doctor's TARDIS, but found that all three of their ships had merged before the craft began being consumed by the white energy that the Doctors had now traced to the Void. When the Eighth Doctor arrived, he revealed that all of his past incarnations were also trapped in the Void. Leaving their eighth incarnation to safeguard Earth, the other Doctors flew into the Void in Jenny's bowship and discovered that the universe was being caused by a Type 1 TARDIS that their eleventh incarnation had failed to correctly pilot. After being updated by the Eleventh Doctor to his situation, the other Doctors realised that the Type 1 could be made to listen to another TARDIS, linking it to the prior versions of their ship and having it jettison all that it had consumed. With the crisis over, the Twelfth Doctor returned to St Luke's University with his ninth, tenth and eleventh incarnations, and bade his past incarnations and their companions farewell, with Jenny opting to leave with the Ninth Doctor. (COMIC: The Lost Dimension)
The Doctor took Bill to Plex's adopted home planet to see the first generation born independently, only to find them to be hostile. With the Chameleon Arch biodata module having broken since he last used it, the Doctor instead brought the planet to peace by telling the clones a glamourised version of their history. As they flew away in the TARDIS, the Doctor told Bill about his history with Plex. (COMIC: The Promise) The Doctor then took Bill to see the coronation of Queen Elizabeth II in 1953. When he asked her what she thought, Bill stated that she preferred Victoria's coronation. (COMIC: Where's the Doctor?)
The Doctor and Bill tracked what appeared to be a shooting star to the village of Little Smallington. Arriving at the village hall, they learned the star was actually a hog-shaped multi-function recycling drone on a rampage because of its overheated nuclear reactor. With the aid of the young Smallington Secret Squad, they lured "Hangry the hog" into a trap using all the metal they could find that resulted in the mechanical hog landing in a river. After the Doctor retrieved him from the river and fixed his reactor, the Secret Squad decided to keep the now-friendly Hangry as a mascot. (COMIC: Loose in the Lane)
Urging to see the universe again, the Doctor answered a distress beacon from Chasm Forge, bringing Nardole with him and Bill when he tried to stop the Doctor leaving. Finding the station overrun with dead bodies reanimated by their smartsuits, and the oxygen limited to those suits, the TARDIS crew put themselves into the suits and were updated on the situation by the survivors, Tasker, Ivan, Abby and Dahh-Ren. When the survivors needed to escape the deceased crew by walking outside the station, Bill's smartsuit malfunctioned and removed her helmet, leaving her exposed to the vacuum of space. After she lost consciousness, the Doctor gave her his helmet, causing him to lose his vision as a consequence of being exposed to the vacuum. Realising that the smartsuits were killing people because they were designed to by the company who created them, Ganymede Systems, to remove the expensive workers, the Doctor linked the survivors' with the power system of the station, leaving it so that the whole station would explode if the smartsuits killed any of them. Telling the spacesuits A.I. his actions and that it would result in Ganymede Systems losing a lot of money, the suits became non-hostile and let the Doctor and the survivors leave.
Having his eyes' appearance restored, but secretly still leaving him blind, the Doctor dropped Ivan and Abby off at Ganymede Systems Head Office to make a complaint, and returned Bill back to his office at St Luke's University, where he revealed to Nardole that he was unable to restore his vision. (TV: Oxygen) Using his sonic sunglasses to see, the Doctor was outside the Vault when he recovered an email titled Extremis. It came from his "Shadow World" counterpart, warning him of an impending attack by the Monks. (TV: Extremis)
After a pyramid appeared in Turmezistan, the Doctor, as the President of Earth, was called upon to deal with the situation by the Secretary General of the United Nations. At the pyramid, the Doctor, Bill, Nardole, the Secretary General, US Colonel Don Brabbit, Russian official Ilya Svyatoslavovich and China official Xiaolian were shown a vision of an apocalyptic Earth by the Monks, who demanded the Earth surrender to them out of love so they could prevent that future from happening. The Doctor refused to, but the Secretary General took the offer out of fear, and was killed for giving the wrong consent.
Setting out to determine the cause of the world ending threat, the Doctor came to the conclusion that they were dealing with a bacteria that would be accidentally released soon. Hacking the CCTV cameras of all the labs on the world to see which one the Monks would reactivate, the Doctor and Nardole went to Agrofuel Research Operations to prevent the catastrophe, while Bill, Brabbit, Svyatoslavovich and Xiaolian went to negotiate with the Monks. At the lab, after ordering Nardole to move the TARDIS and get himself to safety from the bacteria, the Doctor learned from Erica that a misplaced decimal point had resulted in the creation of the deadly bacteria. With the lab's automatic vent systems primed to send the bacteria into the atmosphere in a short time, the Doctor rigged an explosion to sterilize the lab and destroy the bacteria before it could be released.
However, the Doctor became trapped in the part of the lab about to be destroyed when his sonic sunglasses couldn't read the combination lock to the lab door. With Nardole not responding, the Doctor admitted he was blind to Bill and, though he was prepared to die for his mistake, Bill, as the last remaining representative, surrendered Earth to the Monks in exchange for them restoring the Doctor's vision, telling the Doctor the Earth needed him too much. With his vision returned, the Doctor escaped the lab, but was telepathically told by the Monks that he would only "see [their] world." (TV: The Pyramid at the End of the World) As Earth fell to the Monks, the Doctor pretended to be loyal to them to lure them into a sense of security as he planned a revolution. As part of his deception, the Doctor wrote and produced propaganda for the Monks aboard a prison boat off the coast of Scotland, slowly freeing the minds of his guards from the Monk's control. Once Nardole had recovered from the bacteria, the Doctor updated him on the situation.
After six months of the Monks' rule, and on Nardole's suggestion, the Doctor had him bring Bill to him, but not without making sure the Monks weren't affecting her. Once Nardole had brought Bill to the prison boat, the Doctor acted as if he was truly working with the Monks, and sent in his guards to hold Bill at gunpoint, having already told his guards to use blanks to avoid a fatality. When his manipulations caused Bill to grab a pistol and shoot him, the Doctor faked a regeneration to completely fool Bill, admitting to the test after he ended the regeneration effect. Knowing that Missy would have information on the Monks, the Doctor and his companions stole the prison boat to sail to Bristol.
Arriving back at St Luke's University, the Doctor and Bill entered the Vault to converse with Missy, who revealed that the only known way to stop the Monks was to kill their "lynchpin", not knowing that this was Bill. The Doctor refused to sacrifice Bill and instead set out to the Monks' headquarters in London, where the Giant Monk was transmitting the Monks' signals from strategically placed statues, with the Doctor planning to sacrifice himself by destroying the Giant Monk. After they managed to breach the Cathedral, the Doctor was unable to overpower the Giant Monk, and was restrained by Bill and Nardole to prevent him stopping Bill sacrificing herself, but she was able to survive by thinking of her mother, with a memory "so pristine" that it managed to break the Monks' conditioning. With humanity starting to realise the false history of the Monks, the Monks chose to flee the planet, erasing all memory of themselves as they did so. With everything returning to normal, the Doctor returned to the Vault, where he listened as Missy revealed she was starting to feel guilt for the lives she had taken in the past. (TV: The Lie of the Land)
The Doctor was tricked by Ziggy when she swapped bodies with Bill, but her plan was foiled by Bill and Lou, who were able to reverse the body swap. Ziggy then explained that she had wanted them return her to her home planet, Onhwhie, as she had been exiled for speaking up against the unjust government. After some persuading from Bill and Lou, the Doctor agreed to return Ziggy to Onhwhie. (PROSE: Bill and the Three Jackets)
While taking Bill and Nardole to NASA, the Doctor witnessed the discovery of a message reading ""GOD SAVE THE QUEEN"" on the surface of Mars, and went to investigate in 1881. After sending Nardole to get supplies from the TARDIS, it dematerialised due to a glitch, trapping the Doctor and Bill on Mars. As they continued to investigate, they discovered that an Ice Warrior named Friday had brought a platoon of British soldiers, led by Colonel Godsacre, with him to Mars to reward them with Martian treasures for assisting him in his return. When the Ice Queen Iraxxa reawakened upon the discovery of her tomb, the human soldiers opened fire on fire in a panic, and she declared war on them. As Godscare was overthrown in a mutiny lead by Neville Catchlove, the Doctor and Bill were imprisoned with him as the humans fought the reawakened Ice Warrior army.
With the aid of Friday, they escaped. After Godscare executed Catchlove when he took Iraxxa hostage, the Doctor helped the Victorians and the Ice Warriors form a truce, subsequently helping them make contact with Alpha Centauri, with the Doctor helping Godscare to leave the ""GOD SAVE THE QUEEN"" message to help the Galactic Federation find the Ice Warriors. As the two armies departed, the Doctor and Bill were rescued by Nardole and Missy, Nardole having let her out of the Vault to assist him. (TV: Empress of Mars)
While the Doctor was trying to take Bill to see a polar bear, the TARDIS was diverted to an island in the North Atlantic in the 9th century, where they discovered Ice Warriors led by Grand Marshall Sskoll and Vikings. To the Doctor's horror, he discovered that the Ice Warriors were in pursuit of a strain of the Flood, and that his old enemy, Fenric, was plotting to use the Flood to contaminate the Earth's water supply so that he could take over. The Doctor convinced a Haemovore to destroy the Flood on Earth for mutual benefit by detonating a nearby volcano, because if Fenric's plot succeeded, it would erase the Haemovores from existence and replace them with the Flood. As the surviving Ice Warriors, Haemovores and Vikings left, the Doctor and Bill got to see a polar bear. (COMIC: The Wolves of Winter)
Answering a summons from Kate, the Doctor and Bill arrived in Piccadilly Circus to find everyone caught in a phase-shift into another plane. Upon entering the plane, the Doctor and Bill learnt that the Kar-yns were using the Memetic Achieve to manipulate their host into reviving them. While the Doctor distracted them, Bill convinced the host to reject the Kar-yn, and they were destroyed, reverting everything to normal. (COMIC: Tulpa)
Wanting to prove his superior knowledge of the Ninth Legion, the Doctor took Bill and Nardole to 2nd century Aberdeen to solve the mystery of their disappearance. Separating from Bill, the Doctor and Nardole found corpse drained of the absorbed sunlight in their body, and were taken prisoner by the Picts. After learning that their leader, a young girl named Kar, made claim to destroying the Ninth Legion in her role as "the Gatekeeper", the Doctor and Nardole escaped to a Cairn, where the Doctor found a rift leading to a dimension of Light-eating locusts. Though he only stood in the dimension for a few seconds, when he returned to Aberdeen, he found that two days had passed, with Nardole having joined the Picts and been unable to find Bill.
After Kar confessed to releasing the "Eater of Light" to destroy the Ninth Legion, Bill appeared with the remaining Roman soldiers, and the Doctor was able to broker a peace between the Pict and Roman children. With the two armies working together, the Doctor had them draw the Light-eating locust to the Cairn and force it back through the rift. While the Doctor intended for himself to enter the other dimension to fight off the horde of locusts, he was overpowered by Bill and the Picts, and had his place voluntarily taken by Kar and the Ninth Legion, who entered the rift as the Cairn collapsed. Returning to the TARDIS, the Doctor told Bill and Nardole of Missy being locked in the TARDIS, and allowed her to hear the music of the Picts as they talked about their old friendship. (TV: The Eaters of Light)
Tracking an old Dalek harvest ship to Gosligi's Branch, the Doctor tricked the ship into beaming him and Bill aboard, and he was able to override it back into a "basic function", rendering the ship harmless. He then gave the ship to the people of Gosligi's Branch. (COMIC: Harvest of the Daleks)
The Mondasian colony ship
Deciding to give Missy a proper test of character, the Doctor convinced Bill and Nardole to let her lead a rescue mission with them by responding to a distress call. Finding a colony ship heading towards a black hole, the Doctor's test ended when Bill was shot and taken away by the ship's crew. The Doctor, Missy, and Nardole took the elevator to the bottom of the ship in pursuit. (TV: World Enough and Time) As they descended, a time portal with a humanoid hand reaching out, but the Doctor was unable to properly examine the anomaly before it disappeared. (COMIC: The Road To...) The Doctor, Nardole and Missy eventually arrived on the one-thousand-and-fifty-sixth floor to find Bill converted into a Mondasian Cyberman, as Missy teamed up with her previous incarnation, who gloated that they were witnessing the "Genesis of the Cybermen". (TV: World Enough and Time) Despite being attacked and subsequently overpowered by the pair as Nardole fled, the Doctor was able to update the computer algorithm to include two heart species in the Cybermen's hunt before he lost consciousness.
After he woke up on the roof to hear the Master and Missy gloating about their victory and Cyber-converted Bill posed behind, the other Cybermen received the update, leading to the army to lay siege to the hospital. However, the Doctor signalled Nardole to collect him in a stolen shuttlecraft. As the two Masters climbed aboard, the Doctor was grabbed by a Cyberman and electrocuted severely. Heavily wounded, the Doctor collapsed, slowly losing consciousness as he saw Bill come to his rescue and transported him to the shuttlecraft, carrying him out when they crash landed on Floor 0507. The Doctor spent the next two weeks recovering on the floor's solar farm under Hazran's care, as his body prepared to regenerate, despite the Doctor's efforts to resist it.
After helping Bill come to terms with her situation, the Master arrived to take them to Missy, who had found the floor's lift. Once they reached Missy, she unwittingly called upon the Cybermen by activating the floor's lift. After fighting off the lone Cyberman, the Doctor began to prepare defences and make an evacuation plan for the farm. When the Master and Missy made to leave, the Doctor confronted them, begging them to stay and help, to no avail, aside from Missy briefly considering it. Realising that the Cybermen would eventually attack, the Doctor forced Nardole to lead the evacuation to Floor 0502, with only Bill staying with him to face the Cybermen. After they separated to their posts, the Doctor faced the army of Cybermen by blasting as many as he could with Nardole's software hacking of the ship's systems, but was eventually surrounded and struck down by multiple shots. Holding back his regeneration energy as it overcame him, the Doctor detonated the entire deck, killing all the Cybermen in the area, as well as fatally injuring himself. (TV: The Doctor Falls)
Refusing to change
Sometime later, the Doctor awoke in the TARDIS with no clue as to how he got there, (TV: The Doctor Falls) believing he had staggered into the console room after the explosion and simply collapsed. (PROSE: Twice Upon a Time) Entering a "state of grace", (TV: Twice Upon a Time) the Doctor declared he would not go on living if it meant becoming someone else, and consciously halted the regeneration process. In response, the TARDIS took him to a snowy landscape, where the Doctor, still refusing to change, found himself face to face with his first incarnation (TV: The Doctor Falls) just before his regeneration at the South Pole in December 1986. The First Doctor, not realising that he had returned to the wrong TARDIS, mistook the Twelfth Doctor for another Time Lord who had come to take his TARDIS back, just as time suddenly froze around them and a World War I Captain appeared out of the snow. As a bright light shined upon them, the Doctors and the Captain retreated into the TARDIS where the Twelfth Doctor convinced the First Doctor of his identity as the TARDIS was pulled into inside a hovering spaceship.
As the First Doctor was sent out as a distraction, the Twelfth Doctor worked on getting the TARDIS working, until he overheard a Glass Woman offer Bill Potts in exchange for the Captain, and went to embrace her, though expressed disbelief at Bill's seemingly miraculous return. The Doctor examined the Glass Woman with the First Doctor, who realised that the Glass Woman was based on a real person and, at the prompting of Bill, the Twelfth Doctor chose to flee. Lowering the winch holding the TARDIS, the Doctor was able to escape the spaceship with Bill, the Captain and his first incarnation, who lead everyone to his TARDIS. The Twelfth Doctor, knowing that their best chance of stopping Glass Woman was to discover who she was, and that the First Doctor's TARDIS databanks were incomplete, decided to visit his "old friend" Rusty the "good Dalek" for the information and piloted the First Doctor's TARDIS to Villengard.
Upon arrival, the Captain was attacked by a Kaled mutant, and the Twelfth Doctor, still not entirely trusting her, ordered Bill to stay in the TARDIS to help him recover. Walking with the First Doctor, the Twelfth Doctor was forced to rest when his state of grace weakened him, and took the time to discuss regeneration with his first incarnation until they came under attack from Rusty in a tower. After getting Rusty to scan him and see that he was already dying, Rusty stopped and allowed the Twelfth Doctor to enter his tower. Leaving the First Doctor behind for his own protection, the Doctor greeted Rusty in the tower, and negotiated with him for access to the Daleks' Pathweb by reasoning that helping him would "hurt the Daleks". From the Pathweb, the Doctor learned of the Testimony's benevolent agenda (TV: Twice Upon a Time) but immediately realised the real Bill Potts was not with him on the planet. (PROSE: Twice Upon a Time)
As time froze again, the First Doctor arrived with Bill, who officially revealed herself to be a glass avatar and reminded the Doctors that the Captain had to die at his allotted point in time to correct the timeline error caused by the two Doctors "trying to die twice in the same lifetime". Knowing they were to blame, the Twelfth Doctor requested for him and the First Doctor to be the ones to return the Captain to 1914, which was agreed to. On the return flight to 1914, the Twelfth Doctor did his best to comfort the Captain, who commented on how he had promised his wife that he would be home for Christmas, giving the Twelfth Doctor the idea to adjust the time period for the Captain by a couple of hours and make it so that time resumed for him at the beginning of the Christmas Armistice. (TV: Twice Upon a Time) He made a quick visit to Gladys Presley to reclaim two alien communicators, but decided not to when he saw her using them to speak with her son, Elvis. (PROSE: That's All Right, Mama)
As the Doctors and the Glass Woman returned the Captain to the crater where he was supposed to die, with a perception filter rendering them invisible, the First Doctor agreed to the Captain's request for the Doctors to look in on his family, the Lethbridge-Stewarts, from time to time. Once time resumed, the Glass Woman departed and the Doctors watched as the Captain and his German opponent prepared to kill each other before both sides of the battlefield began singing Christmas carols, signalling that the Twelfth Doctor's plan had worked, as he explained the Christmas Armistice to his first incarnation. After watching the Armistice for a few hours, the Doctors shook hands as they started glowing with regeneration energy. Bidding farewell to each other after the First Doctor decided that he was ready to regenerate, the Twelfth Doctor told him to go "the long way round" to see if he was ready to face his own. As his first incarnation departed, the Doctor, briefly rendered visible, saluted the Captain, a salute he returned with confusion. (TV: Twice Upon a Time)
Wrapping himself in his Crombie coat as he sat alone on the battlefield, the Doctor was joined by Bill's glass avatar, who he decided to take "one last stroll" with as she assisted him back to his TARDIS. After the Testimony restored the Doctor's memories of Clara Oswald, a glass avatar of Nardole arrived to convince the Doctor not to die as "everybody in the universe might just go cold" if he did. The Doctor expressed a desire to have peace and rest which his friends agreed that he could as it was his choice and expressed understanding as they shared a final "cuddle" before the glass avatars teleported away.
Deciding that it was "time to leave the battlefield", the Doctor returned to his TARDIS, where he looked at the universe through the scanner and declared that "they [would] get it all wrong without [him]" and contented that "one more lifetime [wouldn't] kill anyone", (TV: Twice Upon a Time) as he finally understood that it was he himself who kept evil from winning over good in the universe. (PROSE: Twice Upon a Time) Holding back the regeneration for a few more moments, the Doctor gave an advisory speech to his successor. Having said his peace, the Doctor underwent an explosive regeneration into a female incarnation, which caused the control room to sustain extensive damage. (TV: Twice Upon a Time)
As the Thirteenth Doctor continued to recover from the immediate after effects of the regeneration, she heard the voice of the Twelfth Doctor continue to speak to her, helping her to remember instances from their previous incarnations that related to the new sensations she was feeling, and gave her some final advice until the TARDIS began experiencing "multiple operation failures". (COMIC: The Many Lives of Doctor Who) As his new incarnation crashed through the night sky above Sheffield, the Twelfth Doctor tried to argue with her to distract her from her imminent plummeting to the ground. (PROSE: Things She Thought While Falling)
- Speaking to an unseen audience, the Twelfth Doctor explained the workings of the bootstrap paradox by using a hypothetical situation of a man with a time machine using his knowledge of Ludwig van Beethoven to travel back in time and inadvertently became Beethoven as a result. (TV: Before the Flood)
- During the time when he had grown out his hair, the Twelfth Doctor visited Daughter of Mine during her imprisonment in the mirrors to ask her whether she was sorry. She never did apologize to him and in fact considered him "the worst." (AUDIO: Shadow of a Doubt)
- At one point, the Twelfth Doctor left the Pandora Bolt with Jim and Midge in 2020 London, along with specific instructions to leave the two puzzle boxes a distance of one mile apart, in each of their shops. (AUDIO: Lost Property)
- The Twelfth Doctor visited the Chibolg Mega-Stamps Convention on Ghent, and prevented a massacre that would have resulted in a war. He then paid the staff to cater to the Ninth Doctor, who arrived soon after, and give him a room to relax in. (PROSE: A Day to Yourselves)
The Doctor and Clara became involved in a "Multi-Doctor Event" with the Tenth Doctor, Gabby Gonzalez, the Eleventh Doctor and Alice Obiefune due to the machinations of an alternate timeline version of the Twelfth Doctor who had joined with the Voord after being "betrayed" by Clara, and was manoeuvring events to ensure his existence. However, though he was able to set his younger counterpart on the path to joining with the Voord, his plot was undone by Gabby being sent back in time by a Weeping Angel and giving her younger self a warning. (COMIC: Four Doctors)
The Twelfth Doctor was portrayed by actor Peter Capaldi in the BBC science fiction series Doctor Who, who was cast in 2013; (PROSE: A Letter from the Doctor 464) an advert which had an obscured image of Capaldi in his role was applied to the side of a bus (TV: In the Forest of the Night) in November 2014; (PROSE: "Assesing the Risk") in October 2015, Capaldi was in the ninth series of Doctor Who; (WC: The Zygon Isolation) and on 29 April 2016, Capaldi wrote a letter to be printed in the 500th issue of Doctor Who Magazine. (PROSE: A Letter from the Doctor 500) The Eleventh Doctor also saved Capaldi from a Mandrel. (COMIC: The Girl Who Loved Doctor Who)
Starting his life as a cynical man with a dry, acerbic wit, brutal honesty and fierce internalised anger, the Twelfth Doctor adopted a less caring attitude and a more hostile nature, (TV: Deep Breath, Robot of Sherwood, Kill the Moon, Dark Water) though he believed he always gave other people the benefit of the doubt. (PROSE: The Blood Cell)
Quick to recover what he could in the midst of sudden tragedy, (TV: Thin Ice) he was willing to sacrifice others, with broader goals in mind, (TV: Into the Dalek) sometimes even devising a masterplan in which others' skills would prove useful. (TV: Time Heist) The Twelfth Doctor regularly monologued to himself, or lectured those around him, while processing a new dilemma, revealing a faith that he always had the right answers — or the power to find them through reason alone — provided he could find "the right question[s]". (TV: Deep Breath, Listen, Heaven Sent)
Later, after embracing the idea that he was "an idiot", (TV: Death in Heaven) the Doctor employed a kookier demeanour. (TV: The Magician's Apprentice, The Zygon Invasion) With the help of Clara Oswald, he tried harder to be social, to show more compassion, (TV: Under the Lake) while still maintaining his pragmatic ideology. (TV: The Girl Who Died, Thin Ice) However, the Doctor did not cope well with losses or endings, and would regain his hostility when angered or threatened with such prospects. (TV: The Witch's Familiar, Face the Raven, Hell Bent)
After losing Clara and having those memories erased, the Doctor finally allowed himself to live out his final night with River Song, having long avoided Darillium. (TV: The Husbands of River Song) Afterwards, he accepted that everything must come to an end. No longer paranoid of the inevitable, the Doctor became more relaxed, amenable and adventurous, with a kinder approach to how he handled situations. (TV: The Return of Doctor Mysterio, The Pilot, Thin Ice, Oxygen, Empress of Mars) Beneath the fierce determination and adventurous persona, the Twelfth Doctor was a weary man who would succumb to despair when pushed to the brink. (TV: The Girl Who Died, Heaven Sent, Hell Bent, The Return of Doctor Mysterio, Extremis, The Doctor Falls, Twice Upon a Time)
Developing on the notion that he had been "an idiot", (TV: Death in Heaven) the Doctor saw the error in his earlier claims of knowledge, remarking that "only idiots" thought they knew the answers. He told Bill Potts he did not count himself among them. (TV: Thin Ice) Nonetheless, when presented with the answer to a riddle, the Doctor was willing to sacrifice his own life to read it for himself, unwilling to let knowledge go. (TV: Extremis) The Daughter of Mine considered him "the worst" incarnation despite him visiting her at a time (WC: Shadow of a Doubt) when he was actively kind, if sarcastic. (TV: The Return of Doctor Mysterio, Twice Upon a Time, et. al) Indeed, the Twelfth Doctor, like his other selves, was simply asking her if she was sorry for her crimes. (WC: Shadow of a Doubt)
Even though he identified himself as a pacifist (COMIC: Terrorformer) and believed necessary evils were the last resort, (COMIC: The Fractures) the Twelfth Doctor showed even less restraint than his predecessor, and would get frank and physical with others. (TV: Deep Breath, Robot of Sherwood, Hell Bent, Thin Ice, World Enough and Time) He claimed he was "always angry", in conversation with the Master. (COMIC: Doorway to Hell) However, Clara felt that "there were several layers to the Doctor's emotions." (PROSE: Silhouette) Beneath the cold exterior present during his early days, the Doctor was extremely self-reflective, even questioning his own motives. (TV: Into the Dalek, Mummy on the Orient Express)
The Doctor used humour to try to help others, hoping his jokes would distract those with him from crumbling under the pressure and fear. (TV: Oxygen) The Doctor was well aware that he often found himself in situations that forced him to make terrible decisions (TV: Mummy on the Orient Express) and believed he was "overbearing, manipulative and consciously aware of his own intelligence". (TV: Time Heist) Worrying for a time if he was a "good man", he came to the conclusion that he was neither good or bad, instead resolving that he was "an idiot, with a box and a screwdriver, [...] passing through, helping out, [and] learning". (TV: Death in Heaven) He described himself as "just a bloke in a box telling stories", (TV: The Witch's Familiar) but hoped others would see him as a "scary, handsome genius from space" (TV: Smile) who was "adorable, hugely intelligent, but still approachable". (TV: The Pyramid at the End of the World)
The Doctor hoped to one day find Gallifrey, and reacted with devastation when his first hope of finding it turned out to be a false lead. (TV: Death in Heaven) On arriving there, he almost immediately deposed Rassilon, exiling him from what he believed to be "[his] planet". (TV: Hell Bent) Viewed as an egotist by Clara Oswald, (TV: Robot of Sherwood) the Doctor had a consistently anti-authoritarian attitude, only ever asking who was in charge so he could "know who to ignore", (TV: Under the Lake) saw it as his place to give the explanations (TV: Last Christmas) and also did not like it when somebody else tried to name something before he did, claiming it was also his place to "do the naming." (TV: Sleep No More) He confessed to Lucy Fletcher that he "hardly ever listen[ed] when other people [were] talking". (TV: The Return of Doctor Mysterio)
Despite coming across as uncaring, especially during his early days, with a complete disregard for social niceties, he would fight to protect those in his care, that being all of humanity, and would often react with devastation if harm befell them. (TV: Deep Breath, The Witch's Familiar, The Girl Who Died, Face the Raven, The Doctor Falls) He would also regret the deaths of good people, especially if the survivors displayed an unpleasant attitude. (TV: Flatline) For a time, for the most part, the Doctor preferred to largely keep his softer side hidden under a "reputation for grumpiness", (COMIC: The Hyperion Empire) making him act callously towards grieving individuals. (TV: Into the Dalek, Mummy on the Orient Express, Dark Water, The Girl Who Died) He would leave murdered bodies he found undisturbed to avoid either awkward questions or the cause of the killing (PROSE: Silhouette, The Crawling Terror) and neglect to ask for people's names because those were "not [his] area". (TV: Deep Breath, In the Forest of the Night) As he began to act kinder, he eventually began using cue cards to help him socialise. (TV: Under the Lake, Face the Raven)
The Doctor also showed a strong compassionate streak, running into a burning library to save Lafcardio from being ejecting into space, (PROSE: The Blood Cell) putting himself in harm's way to save Maisie Pitt from the Foretold, (TV: Mummy on the Orient Express) assisting Clara even after she had attempted to blackmail him, (TV: Dark Water) giving Davros some of his regenerative energy to allow him to see a Skarosian sunrise before he died, (TV: The Witch's Familiar) sacrificing his TARDIS key to reunite Anahson with her mother (TV: Face the Raven) and giving his space helmet to Bill Potts to save her being exposed to the vacuum of space. (TV: Oxygen) He would also try to avoid harming those who were not in control of their actions, as well as defend them from their captors or those who would cause them further harm. (PROSE: Silhouette, The Crawling Terror) He also quickly forgave Clara for betraying him, (TV: Dark Water) forgave Bonnie entirely for her actions against humanity (TV: The Zygon Inversion) and even forgave Missy for all her crimes, (TV: Extremis) going so far as to convince her to change for the better. (TV: The Lie of the Land, The Eaters of Light, World Enough and Time, The Doctor Falls)
While he described himself as having had "sophistication and timeless sartorial elegance" restored, (COMIC: Terrorformer) the Doctor was not above acting childish; requesting a children's menu at Mancini's Family Restaurant, (TV: Deep Breath) wriggling his toes to make the pigs on his socks dance, (PROSE: The Blood Cell) whistling "Another Brick in the Wall" to annoy Clara, (TV: The Caretaker) doing a victory dance after moving the TARDIS off a train line, (TV: Flatline) ecstatically steering Santa Claus's sleigh, (TV: Last Christmas) looking for ways to avoid concentrating on something he did not want to dwell on, (TV: The Doctor's Meditation) having impulses to blow things up (TV: Smile) and bickering with the likes of Robin Hood and Father Christmas. (TV: Robot of Sherwood, Last Christmas) He also got excited when he was inside a Dalek, (TV: Into the Dalek) enthusiastically tried to find out the cause of his childhood nightmares, (TV: Listen) was delighted when he finally saw the Foretold, (TV: Mummy on the Orient Express) got giddy over possibly finding out the existence of ghosts, (TV: Under the Lake) was very eager to explore a mysterious house (COMIC: Playing House) and gleefully laughed as he sped a ship into British waters. (TV: The Lie of the Land) Kevin Alperton noted that, while the Doctor looked old, he had an energy to him that made him seem younger and different. (PROSE: The Crawling Terror)
Though he liked humanity for its optimism, (TV: Smile) the Doctor would insult humans as being slow-minded, greedy and violent, dubbing Earth the "planet of the pudding-brains." (TV: Deep Breath, The Caretaker, Kill the Moon, In the Forest of the Night, The Girl Who Died, Sleep No More, The Lie of the Land) Nonetheless, he tolerated the company of those who could engage him intellectually, (TV: Mummy on the Orient Express, Death in Heaven, Under the Lake, The Pyramid at the End of the World) unless they got on his bad side first, (COMIC: The Fractures) and claimed to respect humanity enough to allow it to determine its own future without any interference from him, (TV: Kill the Moon) giving insight and knowledge to those who would listen, while still leaving the decision up to humanity. (TV: Thin Ice) As with his previous incarnation, the Twelfth Doctor also liked people who got straight to the point, thought that someone who wasn't scared in a life-threatening situation was an idiot (TV: Last Christmas) and would have them focus on their chances of survival, however slim, to encourage them to prevail. (TV: The Magician's Apprentice)
Unlike his immediate predecessor, the Twelfth Doctor was not an affectionate individual, failing to return hugs, or protesting against them, (TV: Deep Breath, Listen, Time Heist) believing they were just another way to hide one's face, (TV: Death in Heaven) but claimed that they were also a good way to smell someone's hair. (PROSE: The Blood Cell) He also expressed a dislike of holding hands with others but made an exception for Clara and Shona McCullough. (TV: Dark Water, Last Christmas, Sleep No More) He drew the line at performing a "high five" with Clara. (TV: Under the Lake) However, he hugged Clara to comfort her after she was almost shot (PROSE: The Blood Cell) and again when they parted ways. (TV: Death in Heaven) Over time, the Doctor began to accept Clara's attempts to hug him, (TV: Last Christmas, The Woman Who Lived, Face the Raven) and even started hugging her on the odd occasion. (TV: The Magician's Apprentice, The Girl Who Died) By the time he reunited with Maxwell Edison, the Doctor had accepted being a hugger, giving an affectionate one to Max, (COMIC: The Stockbridge Showdown) and embracing the chance to hug Bill after losing her in a conflict with the Cybermen. (TV: Twice Upon a Time)
Uncomfortable with kissing, he was momentarily dumbfounded when Maid Marian pecked him on the cheek in gratitude for saving her (TV: Robot of Sherwood) and reacted with horror after he was passionately kissed by Missy. (TV: Dark Water) However, he pecked Missy on the lips in gratitude for forcing him into self-reflection, (TV: Death in Heaven) kissed Clara's forehead while complimenting her brilliance in a moment of excitement, (COMIC: The Big Hush) gave Meghan, a donkey he had befriended, a kiss on the head when he thought no one was looking (PROSE: All the Empty Towers) and kissed Clara's hand as a farewell gesture before she met her death. (TV: Face the Raven) He also accepted kisses on the cheek from both Clara (TV: Last Christmas) and River Song. (TV: The Husbands of River Song)
Much like his seventh and war incarnations, the Twelfth Doctor was, at least during his early days, heavily inclined to err toward a greater good and was willing to allow a few inevitable deaths if it meant saving the majority. Through this attitude, he acted like a pragmatist that would not hesitate to abandon someone whose fate was already sealed, nor mourn for an ally until his objective had been reached. (TV: Into the Dalek, Time Heist, Kill the Moon, Mummy on the Orient Express, The Girl Who Died, Sleep No More, Thin Ice) However, the Doctor was still willing to save people if their deaths were not an immediate inevitability, desperately yelling for people to flee from St Paul's Cathedral when the Cybermen began their invasion, (TV: Dark Water) as well as attempting to save Albert Smithe from the Kantrofarri, (TV: Last Christmas) making a small effort to prevent Alice O'Donnell from being killed in Краснодар, (TV: Before the Flood) and making sure to prevent future colonists from being killed by the Vardy. (TV: Smile) Later, this Doctor rejected the idea of sacrificing people for a "greater good," recalling his experiences at the end of the Time War. (TV: The Zygon Inversion)
Also like his previous incarnations, he relied on his companions to keep him from succumbing to his darker nature, but, unlike his predecessors, the Twelfth Doctor actively praised them for it, even claiming that Clara Oswald needed a "raise" for dealing with him. (TV: Into the Dalek) He also enjoyed it when they asked him obvious questions, claiming that it helped him think, (PROSE: The Blood Cell) but disliked it when they pointed out mistakes he made, (TV: The Return of Doctor Mysterio) and identified them as his "social interface with the human race", (COMIC: The Fractures) and the main reason he didn't need an army. (TV: Death in Heaven)
In stark contrast to his previous incarnations, the Twelfth Doctor was more willing to leave a situation if he believed he had nothing to contribute; abandoning Jason Clearfield when he could not offer medical assistance, (PROSE: The Crawling Terror) abandoning soldiers dying of diseases after solving the mystery of the source, (PROSE: Silver Mosquitoes) leaving Clara, Courtney Woods and Captain Lundvik to decide the fate of the Moon when he felt it wasn't his place to decide for them, (TV: Kill the Moon) and leaving the North Pole base immediately after escaping the Dream crabs, despite Clara claiming the team was still in danger of the Dream crabs still at the base. (TV: Last Christmas) The Doctor justified his attitude by pointing out the dangers of everyday life, claiming that "[everything is] dangerous if you want it to be", and once even pointed out to Clara that he was neither humanity’s mother nor the police. (TV: Kill the Moon, Last Christmas, The Girl Who Died) Later, however, this Doctor had made it his mission to always stay with those he could help, stating it was simply "being kind." (TV: The Doctor Falls)
The Twelfth Doctor preferred to be in the moment, where "everything is huge, everything is so important, every detail, every moment, every life clung to [the moment]." He claimed to the Half-Face Man that the people of Earth "[were] never small to [him]," and, unlike his tenth incarnation, he didn't think he deserved a reward or a "promised land" because he had "already [gone] a very long way [to protect the people]", (TV: Deep Breath) and became a lost soul beyond redemption because of it. (TV: Face the Raven) He also valued mortal lives, however brief they seemed to him, telling Lady Me that she would become his enemy if she executed Sam Swift while he was at her mercy, (TV: The Woman Who Lived) and forbade Weezie from speaking to him after he learned she killed dragons for sport. (COMIC: The Dragon Lord)
He "[found] it best to keep an open mind, unclouded by the opinions of others", favoured the direct approach when he encountered an obstacle, and believed it was always best to assume and plan for the worst-case scenario. (PROSE: Silhouette) He also viewed pain as a gift, telling a Cyber-converted Danny Pink that "without the capacity for pain, [you] can't feel the hurt [you] inflict," (TV: Death in Heaven) and also believed that "a bit of shame never hurt anyone," (TV: The Witch's Familiar) and that true immortality was "everybody else dying". (TV: The Girl Who Died) He was willing to place his companions in danger if it meant appeasing his curiosity, often leaving them out of the details in his plans, or using them to distract attention away from himself. (TV: Deep Breath, The Caretaker, Kill the Moon, Mummy on the Orient Express) However, if he believed the situation was too dangerous for them, the Doctor would send his companions to the safety of the TARDIS while staring down the threat alone. (TV: Listen, Before the Flood, Smile, Twice Upon a Time)
By his own testament, the Twelfth Doctor did not suffer fools gladly, (PROSE: The Blood Cell) nor did he tolerate poor manners, even when held at gunpoint, and he believed that one should make requests politely, (TV: Into the Dalek) as well as avoid bad language, (TV: Kill the Moon, Thin Ice) and gloating. (GAME: The Doctor and the Dalek) He also believed that "hardly anything [was] evil, but [that] most things [were] hungry", and that "hunger look[ed] very [much] like evil from the wrong end of the cutlery". (TV: The Pilot)
He did not see himself as a "hero", merely someone who was "just passing the time", (TV: Robot of Sherwood) or passing by, (TV: The Return of Doctor Mysterio, Smile) but would answer distress signals, believing that he only saw "the true face of the universe when it [was] asking for [his] help." (TV: Oxygen) He also believed that one could always find something to be distracted by, (TV: Into the Dalek) believed that invasions of Earth were justified to those invaders after hearing about the horror film Alien. (TV: Last Christmas) He expressed the opinion that an enemy was "just a friend you didn't really know yet", (WC: Prologue) and was willing to fully forgive his enemies. (TV: The Zygon Inversion, The Eaters of Light)
Though he did not know the reason, believing it to simply be his old age, (PROSE: The Blood Cell) the Twelfth Doctor expressed a strong dislike for soldiers and military figures, (TV: Into the Dalek, The Caretaker, Death in Heaven) being "decidedly prickly in his dealing with anything remotely military", (PROSE: The Crawling Terror) though claimed his disdain was flexible in a crisis. (PROSE: The Blood Cell) However, he showed sympathy towards Captain Quell and the Foretold, (TV: Mummy on the Orient Express) and still retained a respect for the Brigadier. (TV: Death in Heaven) He was also easily annoyed by swashbucklers who did not take things seriously, (TV: Robot of Sherwood) even abandoning a village of Vikings to death in battle due to their insistence on fighting the Mire. However, he quickly returned and helped them, feeling as though he lost in the end because there was one death amongst the villagers. (TV: The Girl Who Died) Believing "progress isn't measured by industry", held a disdain towards business people who valued profit above anything else. (TV: Under the Lake, Sleep No More, Thin Ice)
He also claimed to dislike the colour of his kidneys, (TV: The Time of the Doctor) liver, karaoke, mime, (TV: Deep Breath) babysitters, (TV: Into the Dalek) bantering, (TV: Robot of Sherwood) Candy Crush, (PROSE: The Blood Cell) outside interference, money, being taken prisoner, (COMIC: Terrorformer) salutes, (TV: Death in Heaven) pantomime, (PROSE: Behind You) cyclopes, (COMIC: Doctor on the Menu) tanks, (TV: The Magician's Apprentice) songs that got stuck in his head, (TV: Under the Lake) Tivolians, (TV: Before the Flood) gardening, (TV: Heaven Sent) pears, (TV: Hell Bent) Christmas, (COMIC: Relative Dimensions) "lying-down people", (TV: The Husbands of River Song) fish, (TV: Smile) racism, talking in the cinema, (TV: The Lie of the Land) charm, and "brave people". (TV: The Eaters of Light) He also disliked being wrong in public, (TV: Deep Breath) missing the obvious, (TV: Last Christmas) and being sure of something. (TV: The Husbands of River Song) While he claimed to hate not knowing about something when faced with the Teller, (TV: Time Heist) he was known to admire the unexplainable. (TV: Flatline, Under the Lake) He also told Ohila that, while he trusted her, he didn't necessary like her, (WC: Prologue) and confessed to Osgood that, while he spent a lot of time there, he considered London to be a "dump". (TV: The Zygon Inversion) However, just before his regeneration, the Doctor denounced hate as "always foolish", and proclaimed that "love [was] always wise." (TV: Twice Upon a Time)
While he did not dwell on the subject much, the Twelfth Doctor was still haunted by the War Doctor's actions in the Last Great Time War, and claimed to hear "more screams than anyone could ever be able to count" whenever he closed his eyes and vowed that he would ensure that others would never have to feel the angst he felt, leaving him with an extreme hatred of war, (TV: The Zygon Inversion) even saying the word with contempt in his voice. (TV: The Magician's Apprentice) When he learned that all Bonnie truly wanted was a pointless war between humanity and the Zygons, he went into a furious and grief-stricken tirade by telling her that he knew what war was really like and that he would not allow her to lead others to their deaths. (TV: The Zygon Inversion) While he disliked guns, (TV: The Doctor Falls) he noted that it was foolish to disregard them when they were useful, (PROSE: The Crawling Terror) and was willing to utilise one himself when he felt the need to, but would immediately discard it once it was no longer needed. (TV: The Witch's Familiar, Hell Bent)
The Doctor liked babies and bicycles, which reminded him of Call the Midwife, as well as stars, (PROSE: The Blood Cell) "working under pressure", (TV: Into the Dalek) candy floss, (PROSE: All the Empty Towers) "a show-stopping entrance", (COMIC: Terrorformer) a "good locked-room mystery", (TV: Flatline) porridge, (PROSE: Deep Time) puppets, (TV: The Girl Who Died) sherbet lemons, Ferrari cars, (TV: The Woman Who Lived) "poncing about in a big plane", (TV: The Zygon Invasion) the title "Doctor Mysterio", "pressing buttons and switches", (TV: The Return of Doctor Mysterio) rivets, (TV: Smile) Chinese food, and insects. (TV: Knock Knock)
The Doctor also claimed that 12 was his "lucky number", (TV: The Doctor's Meditation) and had a liking for books, particularly ones about Garfield, reacting with anger towards those he believed burned books, and also believed that women who liked books to be the best kind. (PROSE: The Blood Cell) When he redecorated the TARDIS control room, he included numerous shelves full of a variety of books, and a recliner to enjoy reading them in, (TV: Deep Breath) sometimes even leaving his books scattered around the console room. (TV: Listen, Kill the Moon) He thought football was a "boring sport", but that darts was "something worth practicing," and that "maths and alcoholic beverages" were the "best way to spend the morning", (TV: For Tonight We Might Die) and liked to repay good deeds, such as when Bill Potts gave him a rug for his office, (TV: The Pilot) even though he did not like the rug. (TV: Twice Upon a Time)
The Doctor held a veneration of the dead. As such, he ceased all insults towards Danny Pink after being told of his passing, (TV: Dark Water) was morally outraged with the Fisher King for using the souls of the dead as transmitters for his armada, (TV: Before the Flood) and become hurt when he thought the Testimony had duplicated Bill after she "gave her life so that people she barely knew could live". (TV: Twice Upon a Time) He knew he could always visit the graves of his former friends and read about their lives, but he never allowed himself to; he found that experience nothing when compared to the love and joy he felt when truly reuniting with them again. To the Doctor, the Testimony and the Matrix on Gallifrey were unsatisfying because they were merely ways for avatars to access memories, not a way to truly meet someone again. (PROSE: Twice Upon a Time)
Unlike his immediate predecessor, the Twelfth Doctor was unwilling to alter the Web of Time, fearing that the ramifications from the tiniest changes could be catastrophic, spreading "carnage and chaos across the universe like ripples on a pond," (TV: Before the Flood) instead opting to create "ripples" instead of "tidal waves." (TV: The Girl Who Died) He believed it was okay to send people to their deaths if history recorded them as deceased, (PROSE: The Crawling Terror) and also refused Clara's request to save Danny Pink from being hit by a car due to it being a part of her timeline, and undoing it would cause a paradox. (TV: Dark Water) He also told Mason Bennett that he "[couldn't] just go back and cut off tragedy at the root because you find yourself talking to someone you just saw dead on a slab, [and] then you really do see ghosts".
Nonetheless, he claimed to be willing to change certain points he encountered because "even a ghasty future is better than no future at all". (TV: Before the Flood) He remembered the lesson the Tenth Doctor had learned in Pompeii and marked his face as a way "to hold [himself] to the mark" on how to save others despite the Web of Time. He damned anyone who would have a problem with him saving others to Hell, trying to act in ways that would not damage the Web of Time while also saving those he could. (TV: The Girl Who Died) Emotionally broken after the death of Clara, upon returning to Gallifrey, the Doctor used an extraction chamber to save Clara from the Quantum Shade, and also attempted to prevent her from returning to her death, despite it being a fixed point in time. (TV: Hell Bent) He engineered events to prevent Archibald Hamish Lethbridge-Stewart and a German soldier from killing each other, claiming that "a couple fewer dead people on the battlefield" would not "hurt". (TV: Twice Upon a Time)
Though he initially stated that murder was against his "programming", (TV: Deep Breath) the Doctor knew there were "situations when the options available [were] limited". (TV: Thin Ice) He showed a willingness to kill the Half-Face Man if he had to, though with some reluctance, first offering him a drink of alcohol and trying to persuade the clockwork droid to self-destruct of his own free will before engaging in fisticuffs. (TV: Deep Breath) He also stated that, despite how much he hated him, he had no intention of killing the Architect, (TV: Time Heist) but was willing to kill Missy to spare Clara from doing it. (TV: Death in Heaven) He did orchestrate the deaths of two Kaliratha that were keeping him prisoner by taking them to a point in time prior to their bodies being discovered, (COMIC: The Swords of Kali) tricked the Fisher King into being engulfed in the deluge of the flood that destroyed Краснодар, (TV: Before the Flood) gave permission for UNIT to engage Zygons with lethal force, so long as they kept fatalities to a minimum, (TV: The Zygon Invasion) fatally shot the General after being assured he would regenerate, (TV: Hell Bent) and left Ron Cordell and some Skinks to be devoured by a black hole after tampering with the black hole drive's containment field. (COMIC: Pirates of Vourakis)
He also appeared to view certain enemy creatures as expendable; he wanted to kill a dream crab to save Clara from slowly being devoured by it, (TV: Last Christmas) crushed a Love Sprite under his heel to prevent it attacking him and Clara, (TV: The Girl Who Died) killed many Daleks throughout his life, (TV: The Witch's Familiar) and destroyed numerous Cybermen during the skirmish in a Mondasian colony ship. (TV: The Doctor Falls) The Doctor indeed hated the mass of graves that followed in his wake, comparing his life to an "empty battlefield" because "everyone else had fallen".(TV: Twice Upon a Time) When Ashildr died, he felt he had lost the day despite winning the battle against the Mire; as he told Clara, he would "lose any war you'd like" because, if people died under his watch, he had lost the day already. Nonetheless, he remembered he had chosen his face because the Tenth Doctor saved Lobus Caecilius from death, which the Doctor took as a lesson that he was "the Doctor and [he] saved people", using that lesson to find a way to save Ashildr. (TV: The Girl Who Died)
An absent minded incarnation, the Twelfth Doctor failed to notice when someone was asking him if they looked attractive, (TV: Into the Dalek, Time Heist, The Woman Who Lived) would go off to a location without asking for directions, (PROSE: Silhouette) had trouble recognising people's age group, (TV: Into the Dalek, The Caretaker, Kill the Moon, Last Christmas, The Return of Doctor Mysterio) believed that minor clothing changes hid his identity, (TV: The Caretaker) could not grasp the concept of an English lesson, (COMIC: The Fractures) would read sentences in their entirety even when he didn't have to, (TV: Under the Lake) and thought he had uncovered Superman's secret identity, despite Grant telling him that it was already a known fact. (TV: The Return of Doctor Mysterio) Like his predecessor, he was also shown to have a poor concept on the passage of time, (TV: The Doctor's Meditation, The Magician's Apprentice, The Zygon Inversion) and would make contradictory statements, such as telling Courtney Woods that she "wasn't special", (TV: Kill the Moon) despite previously telling the Half-Face Man that humanity "never [seemed] small to [him]". (TV: Deep Breath) He also claimed that Clara would hate the "smelly, dirty and dangerous" Arthurian era, but would love the Victorian era for the same reasons, (PROSE: Silhouette) and claimed that, while he found the transmitter ghosts as "evil", he also found them "astonishing", and said he "want[ed] to kiss [them] to death". (TV: Under the Lake) He called London a "cradle of culture", but later confessed to Osgood that he thought it a "dump". (TV: The Zygon Inversion)
The Twelfth Doctor believed that education came quicker in life threating situations, and claimed that begging "wasn't [his] style", (COMIC: Terrorformer) unless his friends were threatened. (TV: The Magician's Apprentice) He also didn't care about sexuality, instead being bothered by people hating each other, and didn't approve of revenge. (COMIC: The Swords of Kali) He claimed that taking charge was his "superpower", (TV: Time Heist) and listed "investigating", "playing with time" and "resistance" among his specialities, (COMIC: Terrorformer, The Swords of Kali, The Fractures) with Clara adding "interfering and infuriating" to the list. (COMIC: Terrorformer)
He had a more celibate nature than his predecessor; dismissing Clara's comments on Silhouette's attractiveness, (PROSE: Silhouette) and not understanding Dr. Chang's suggestion about the application of dark water in public swimming pools. He also described Clara as being "a mess of chemicals" after she professed her love for Danny Pink. (TV: Dark Water) Despite this, he called a female Tyrannosaurus rex a "big sexy woman" while in a post-regenerative state, (TV: Deep Breath) considered Rona Bellows "sexy", partially because of her Scottish accent, (TV: Last Christmas) and shared a mutual attraction with his wife, River Song. (TV: The Husbands of River Song)
After redecorating his console room, the Doctor designed it with a more lived-in state, filling it with bookshelves, chairs, and workbenches, (TV: Deep Breath, The Caretaker) and even once having a meal in it with guests. (TV: Time Heist) He once told Clara that the TARDIS was his house. (TV: Flatline) The Doctor told Bill Potts that the TARDIS was a "technological marvel", "science beyond magic", and "the gateway to everything that ever was, or ever can be." (TV: The Pilot) He did, however, occasionally enact violence against his TARDIS out of frustration, striking its column with his fists hard enough to damage it after discovering Missy's coordinates to Gallifrey had been a lie, (TV: Death in Heaven) and later struck the console with enough force for he to believe he had broken a finger. (PROSE: Deep Time)
While he preferred him to other incarnations, (COMIC: Four Doctors) the Twelfth Doctor disliked his immediate predecessor for his enjoyment of bow ties and fezzes, and overuse of the word "cool". (COMIC: Terrorformer) However, upon seeing Adrian Davies, a teacher at Coal Hill School with a resemblance to his previous incarnation, the Doctor, mistaking Adrian as Clara's boyfriend, arrogantly assumed that Clara was dating Adrian because of his uncanny resemblance to "a certain dashing young time traveller", reflecting more favourably on his predecessor. (TV: The Caretaker) Additionally, he was, at times, critical of his previous incarnations' clothing; thinking that his fourth incarnation's scarf "looked stupid", (TV: Deep Breath) and regarded his immediate predecessor's fondness for bow ties as "a bit embarrassing", (TV: Time Heist) but complimented Osgood's bow tie as "nice". (TV: Death in Heaven) According to Affinity, the Doctor kept his predecessors "lodged in his head", and held a low opinion of them and himself, (PROSE: Silhouette) even comparing a Multi-Doctor Event to The Krankies. (WC: Doctors Assemble!)
While he reflected that the First Doctor was "not much fun", (PROSE: Full Stop) when he encountered his first incarnation, the Twelfth Doctor was delighted by some of his habits, such as still calling the TARDIS "the ship". However, he was embarrassed by the First Doctor's habit of making comments that were inappropriate in the Twelfth Doctor's eyes, especially when he threatened to give Bill a "jolly good smacked bottom" if she kept on swearing. (TV: Twice Upon a Time)
When he met his two previous incarnations, the Doctor had a frosty accord with the Tenth Doctor, who refused to consider the twelfth incarnation as a future incarnation until the Blinovitch Limitation Effect confirmed he was. Conversely, the Eleventh Doctor was willing to accept him as his next incarnation and was happy to know he had more life in the future. While he degraded them as "manic pixie dream Doctors", the Twelfth Doctor expressed concern that the two would come to know him as the "scary Doctor". He held the Ninth Doctor in higher regards, saying the Continuity Bomb could not find a timeline where he wasn't "fantastic". (COMIC: Four Doctors) In a later encounter with his tenth incarnation, the Doctor referred to his predecessor as "Bambi", being dismissive of how overtly emotional he had been and having some embarrassment for his predecessor's obsession with Rose Tyler, but seemed to retain a fondness for that time in the Tenth Doctor's life. (COMIC: Vortex Butterflies) Even after undergoing a more positive outlook, the Twelfth Doctor still disliked the Tenth Doctor for his "excited puppy routine". (COMIC: The Lost Dimension)
The Twelfth Doctor held deep affection for Clara Oswald, considering her to be his best friend, (TV: Mummy on the Orient Express) and cared for her to the point that her betraying him couldn't make a difference to how he felt about her. (TV: Dark Water) His connection with her was so deep that, after her death by Quantum Shade, he respected her wishes to not target Ashildr for her role in the incident, (TV: Face the Raven) However, after spending four billion years in a temporal loop mourning losing her, (TV: Heaven Sent, Hell Bent) he became unhinged, deciding no one would stop him bringing her back, threatening all who tried to prevent him restoring her to life, even forcing the General to regenerate, until events forced him to lose his memories of Clara. (TV: Hell Bent) When his memories of her were restored, he was delighted, thankful he could finally remember her face. (TV: Twice Upon a Time)
Although he tended to be dismissive of Nardole, (TV: The Pilot, Thin Ice, Oxygen, Twice Upon a Time) he still took his advice in stock and chose to sacrifice his own life so Nardole could escape certain death. (TV: The Doctor Falls) He also grew close with Bill Potts, making her his personal student while at St Luke's University, even going back in time to obtain pictures of her mum as a Christmas gift in gratitude for her gifting him a carpet. (TV: The Pilot) He also confided in Bill about his concerns over Missy and made it his personal mission to save Bill from death at the hands of the Cybermen. (TV: World Enough and Time) He also didn't like Bill seeing him physically vulnerable, going as far as not telling her about his blindness, (TV: Oxygen, The Pyramid at the End of the World) or his impending regeneration. (TV: The Doctor Falls)
Despite his grumpy nature during his early days, the Doctor got along well with children, giving a big tip to a little girl selling matches, (PROSE: Silhouette) giving Rupert Pink an enthusiastic pep talk about fear being a super power, (TV: Listen) telling Maebh Arden that her theory of everyone knowing everything but her was "not quite true", (TV: In the Forest of the Night) helping Evie Hubbard with her history homework, (TV: The Woman Who Lived) stopping to tie a young boy's shoelaces while searching for a trap street, (TV: Face the Raven) giving Dottie his bun and top hat as payment for a flyer, (TV: Thin Ice) and telling Alit not be worried after showing kindness to a Cyber-converted Bill. (TV: The Doctor Falls) After realising he had hurt Courtney Woods's feelings, he decided to take her and Clara to the Moon, so that Courtney could be the first girl on the Moon, to help her feel special, (TV: Kill the Moon) and was ashamed with himself when he abandoned a young Davros to the Handmines, to the extent that he felt only death could atone for his actions. (TV: The Magician's Apprentice) He also did not look down at children, and treated their thoughts and suggestions as seriously as he did with grown-ups' ideas and opinions, (TV: Listen, In the Forest of the Night, The Girl Who Died) and was angered when finding babies unattended too. (TV: The Return of Doctor Mysterio)
The Twelfth Doctor's hatred toward the Dalek species was rigid, with Clara describing it as "prejudice", (TV: Into the Dalek) though he did stop to mourn Lumpy, a Dalek that had deceived him into friendship. (GAME: The Doctor and the Dalek) He believed Daleks were incapable of change and was closed-minded as he dealt with their presence, and would refuse to help a Dalek unless his interests were peaked. (TV: Into the Dalek; GAME: The Doctor and the Dalek) After his act of fixing a malfunctioning "good" Dalek caused it to revert to "evil", the Doctor was almost pleased that his belief of there being "no such thing as a good Dalek" was vindicated. (TV: Into the Dalek) Despite his hatred of them, the Doctor admitted to the Governor that the Dalek Emperor "[was] nothing compared to your average mobile phone sales assistant". (PROSE: The Blood Cell) He also held a disregard for the Cybermen, unceremoniously flattening two with his TARDIS, (GAME: The Doctor and the Dalek) and slew many of them in the Battle of Floor 0507, where he was also fatally wounded. (TV: The Doctor Falls) He knew to be cautious around them, (TV: Face the Raven) though he would try to reason with the ones that were "fresh out the factory". (TV: World Enough and Time)
When Rusty the Dalek looked into the Twelfth Doctor's mind, he saw hatred and noted that the Doctor was "a good Dalek", while Clara believed the Doctor was trying to be a good man regardless, (TV: Into the Dalek) and claimed that he "always care[d]" by the time of her death. (TV: Face the Raven) When questioned by Lisa Foster, Clara reluctantly admitted she thought the Doctor was "kind of [cool], in a strange sort of way", which Lisa interpreted as meaning "an uncool sort of way". (COMIC: The Fractures) Bill Potts once described the Twelfth Doctor as "part-cool professor, [and] part-cat chasing laser pointer". (COMIC: The Promise)
The Oracle described the Twelfth Doctor as "a man of taste and discrimination," (PROSE: The Blood Cell) while Orestes Milton believed the Doctor "affect[ed] an air of ignorance and indifference, but beneath it [were] undercurrents of knowledge and curiosity". (PROSE: Silhouette) Perkins noted his inability to decide whether the Doctor was a genius "or just incredibly arrogant". (TV: Mummy on the Orient Express) Danny Pink, in complete bitterness for his need to feel the pain he inflicted, compared the Doctor to a "blood-soaked old general". (TV: Death in Heaven) Ashildr considered the Doctor to be a "passionate and powerful Time Lord". (TV: Hell Bent)
Much as his tenth incarnation expressed, the Twelfth Doctor associated regeneration with death, recalling Snowcap as "the place where he died". He viewed the process as "huge, [and] terrible", with his self-preservation preventing his memories of the experience from consuming him. (COMIC: Blood and Ice) He also believed that regeneration was to be used only when completely necessary, and to use it to fix a broken toe was "a waste of a life". (PROSE: The Blood Cell) Despite his beliefs, when used to extremes, the Doctor, during the period where he was desperate to save Clara on Gallifrey, was willing to force a fellow Time Lord to regenerate if it benefited him. (TV: Hell Bent)
When faced with the prospect of dying without regenerating while facing the Fisher King, the Doctor, though initially appearing distraught, quickly dismissed any concern, saying that he "had a good innings", and labelling himself a mere "clerical error" of a regeneration, telling Clara that "we all have to face death eventually, be it ours or someone else's." (TV: Before the Flood) When cornered by the Veil, the Doctor admitted that he was afraid of dying, (TV: Heaven Sent) but was unafraid to sacrifice himself for the greater good. (TV: The Pyramid at the End of the World, The Doctor Falls)
After the regeneration progress was triggered by an attack from a Mondasian Cyberman, the Doctor, angry at the idea of constantly "being other people", only allowed his regeneration energy to heal the wounds he suffered on the Mondasian colony ship, refusing to change into his next body. (TV: The Doctor Falls) As he was faced with the question on whether to regenerate, he believed it to be his moment of greatest need and thus was distraught to learn the "real" Bill Potts was not there to help him, merely a glass avatar with her memories. (PROSE: Twice Upon a Time)
When confronting the glass avatars of Bill Potts and Nardole, the Doctor confessed he was "tired of losing people" and, feeling "there [had] to be an end", that he only wanted to rest in peace, seeing his long life as "[an] [empty] battlefield, because everyone else [had] fallen". After a final cuddle with the glass avatars, the Doctor decided it was "time to leave the battlefield", and entered the TARDIS alone. Upon looking at the "silly old universe" on the TARDIS scanner, the Doctor, realising that the "more [he] save[d] it, the more it need[ed] saving", decided that "one more lifetime wouldn't kill anyone". Giving instructions to his successor to "never be cruel, [and] never be cowardly", that "hate [was] always foolish, and [that] love [was] always wise", to "never fail to be kind", and to never reveal their name, the Doctor "let [himself] go" and regenerated into a female body. (TV: Twice Upon a Time)
Habits and quirks
Much like his seventh incarnation, the Twelfth Doctor spoke with a Scottish accent, (TV: Deep Breath) which was noted by Bernice Summerfield to be Glaswegian in contrast to the Seventh Doctor's Highlands one. (PROSE: Big Bang Generation) He took his Scottish accent as an entitlement to complain about things, (TV: Deep Breath) and found it attractive in others. (TV: Last Christmas) With his accent, he was prone to making subtle or climactic boasts and threats. (TV: Deep Breath, Into the Dalek, Robot of Sherwood, Mummy on the Orient Express, Flatline, Death in Heaven, The Witch's Familiar, Before the Flood, The Girl Who Died, Face the Raven, Heaven Sent, The Return of Doctor Mysterio, Oxygen, Extremis, The Pyramid at the End of the World, The Lie of the Land, The Eaters of Light, The Doctor Falls, Twice Upon a Time) However, when truly angered, the Doctor would hiss with quiet rage instead of shouting. (TV: Death in Heaven, The Witch's Familiar, The Girl Who Died, Face the Raven, Hell Bent, The Doctor Falls)
When proposing a theory or plan, the Doctor would use words such as "question", "proposition" or "proposal", and would begin his conclusion with "answer", "conjecture", "conclusion" or "plan". (TV: Deep Breath, Listen, Time Heist, The Witch's Familiar, Thin Ice) After working out the important questions and the answers in his head, he waited for others to come to the same conclusion, becoming increasingly annoyed with each wrong question or answer they proposed. (TV: Deep Breath, In the Forest of the Night, Last Christmas, Under the Lake, Sleep No More) He was also known for his soliloquies (TV: Listen, Heaven Sent, The Pilot, Smile, Oxygen, The Pyramid at the End of the World, Twice Upon a Time) and speeches that aimed to educate people for the better. (TV: Into the Dalek, Kill the Moon, The Woman Who Lived, The Zygon Inversion, Thin Ice, Knock Knock, The Doctor Falls)
When in a moment of realisation or thinking intensely, the Doctor would often tell people to "shut up/it", regardless if others would be speaking or not. (TV: Deep Breath, Time Heist, Face the Raven, The Pilot) He would also issue the instruction to those who had earned his ire, regardless of their status, occupation or how petty the ire was, (TV: Robot of Sherwood, The Caretaker, Death in Heaven, Last Christmas, The Return of Doctor Mysterio) and when he wished to avoid a subject of conversation. (TV: Dark Water, Death in Heaven, The Pilot, World Enough and Time) When instructing someone to pay attention, the Doctor would command them to "listen". (TV: Listen, Time Heist, The Caretaker, Flatline, The Zygon Invasion, The Zygon Inversion, The Eaters of Light, The Doctor Falls)
The Doctor made a habit of assigning nicknames to others, giving them names based on their appearance, by an accessory they carried or by their profession, (TV: Deep Breath, Into the Dalek, The Caretaker) owing to the fact he often chose to forget people, (TV: Last Christmas) or didn't have time to remember individual names, (TV: The Girl Who Died) and would insist on addressing them as their nickname, such as calling Danny Pink "P.E.", despite Danny being a Maths teacher, due to seeing him as more of a PE teacher than Maths, (TV: The Caretaker, In the Forest of the Night, Death in Heaven) though he dropped the nickname after Danny died. (TV: Dark Water, Last Christmas) He also continued to address Rigsy as "Local Knowledge" when he was standing in front of him, (TV: Flatline) and when they reunited years later, only dropping the nickname when he learned Rigsy's life was in fatal danger. (TV: Face the Raven)
During his early life, the Twelfth Doctor would often accuse things, even other people, of developing faults, errors and malfunctions when he didn't think they were working the way he though they were meant to, (TV: Deep Breath, The Caretaker, Mummy on the Orient Express, Dark Water) and, like the Ninth Doctor labeling humanity as "stupid apes", he would call them "pudding-brains", or "pudding head", when he found them slow-minded or stupid. (TV: Deep Breath, Robot of Sherwood, Flatline)
Like his ninth and eleventh incarnations, the Doctor often used "hell" as an intensive, (TV: The Girl Who Died, The Zygon Inversion, Face the Raven, Hell Bent, The Pilot, Oxygen, Extremis, The Pyramid at the End of the World, Empress of Mars, The Eaters of Light) and spoke the name of "God" in vain. (TV: Last Christmas, Under the Lake, The Girl Who Died, The Zygon Inversion, Face the Raven, The Husbands of River Song, The Doctor Falls)
The Doctor often made puns, (TV: Into the Dalek, Kill the Moon, Flatline, The Magician's Apprentice, The Witch's Familiar, The Zygon Inversion, The Husbands of River Song, The Return of Doctor Mysterio, Twice Upon a Time) though hypocritically would complain about others making them. (TV: The Woman Who Lived) He was also known to quote media, (TV: Deep Breath, Death in Heaven, The Zygon Inversion, The Pyramid at the End of the World) literature, (TV: The Caretaker, In the Forest of the Night, The Woman Who Lived, Sleep No More, The Husbands of River Song, Oxygen) and song lyrics. (TV: The Caretaker, The Magician's Apprentice, Sleep No More, The Husbands of River Song)
Like his fourth incarnation, the Doctor would talk aloud to himself, (TV: Listen, Mummy on the Orient Express, Under the Lake, Heaven Sent, The Pyramid at the End of the World, Twice Upon a Time) and was even known to act like his was interacting with someone when there was no evidence of him having company. (TV: Deep Breath, Before the Flood) He also utilised a yo-yo on occasion. (TV: Kill the Moon, The Girl Who Died, Oxygen)
Much like his predecessor, the Twelfth Doctor also used hand gestures to extenuate a point, but applied more dedication to his movements, standing firm, while speaking with conviction, and punctuating his points across with a pointed index finger, though would become more spontaneous when thinking intensely. (TV: Time Heist) Commonly, he would stick out his index and baby fingers with his thumb, and lower his middle and ring fingers. (TV: Deep Breath, Into the Dalek, Listen, Time Heist, The Caretaker, Kill the Moon, In the Forest of the Night, Dark Water, Last Christmas, The Doctor's Meditation, The Magician's Apprentice, The Witch's Familiar, Under the Lake, Before the Flood, Face the Raven, Hell Bent, The Return of Doctor Mysterio, Thin Ice, Knock Knock, Oxygen, The Pyramid at the End of the World, Twice Upon a Time)
He was also known to bite down on his hand, (TV: Deep Breath, Into the Dalek, Mummy on the Orient Express, In the Forest of the Night, Under the Lake, Before the Flood, The Zygon Inversion) tap his teeth with his finger, (TV: Kill the Moon, In the Forest of the Night, Last Christmas, The Girl Who Died, The Woman Who Lived, Hell Bent, Oxygen, The Lie of the Land, The Eaters of Light) or cradle his chin in his hand when thinking, (TV: Listen, Kill the Moon, Mummy on the Orient Express, The Witch's Familiar, The Girl Who Died, Hell Bent, Smile, Empress of Mars) gesture by turning his hand with his fingers together and thumb stuck out, (TV: Deep Breath, Into the Dalek, The Caretaker, The Doctor's Meditation, The Girl Who Died, The Woman Who Lived, The Zygon Invasion, Hell Bent, The Husbands of River Song, The Eaters of Light) and interlock his fingers when explaining or contemplating something. (TV: Deep Breath, Into the Dalek, Robot of Sherwood, Time Heist, The Caretaker, Kill the Moon, Mummy on the Orient Express, Flatline, Dark Water, Death in Heaven, Last Christmas, The Girl Who Died, The Zygon Invasion, The Zygon Inversion, Face the Raven, Heaven Sent, Hell Bent, The Husbands of River Song, The Pilot, The Lie of the Land, Empress of Mars)
Much like his previous incarnations, the Twelfth Doctor would often flick his coat back and have his hands in his pockets, (TV: Deep Breath, Into the Dalek, The Caretaker, Dark Water, Death in Heaven, Last Christmas, Under the Lake, Before the Flood, The Girl Who Died, The Woman Who Lived, The Zygon Inversion, Sleep No More, Heaven Sent, The Return of Doctor Mysterio, The Pilot, Smile, Knock Knock, The Lie of the Land, The Eaters of Light, World Enough and Time) and, like his second incarnation, often wringed his hands together, (TV: Into the Dalek, Listen, The Caretaker, Kill the Moon, Mummy on the Orient Express, Flatline, In the Forest of the Night, Last Christmas, The Doctor's Meditation, The Witch's Familiar, Under the Lake, Before the Flood, The Girl Who Died, The Woman Who Lived, The Zygon Inversion, Face the Raven, Heaven Sent, The Return of Doctor Mysterio, The Pilot, Smile, Thin Ice, Oxygen, The Eaters of Light) or hold his thumb in his hand. (TV: Deep Breath, Listen, The Caretaker, Mummy on the Orient Express, In the Forest of the Night, Under the Lake, The Zygon Inversion, The Husbands of River Song, The Pilot)
He also occasionally folded his arms like his ninth incarnation, (TV: Into the Dalek, Listen, The Caretaker, Dark Water, The Girl Who Died, The Husbands of River Song, Empress of Mars) would rest his hands on his hips like his third incarnation, (TV: The Caretaker, Mummy on the Orient Express, Flatline, Death in Heaven, The Witch's Familiar, Sleep No More, Heaven Sent, The Return of Doctor Mysterio, Thin Ice, Empress of Mars) or hold his arms behind his back like his war incarnation. (TV: Mummy on the Orient Express, Last Christmas, Under the Lake, The Woman Who Lived, The Zygon Invasion, The Zygon Inversion, For Tonight We Might Die, Smile, Thin Ice, Oxygen, The Pyramid at the End of the World, The Eaters of Light, Twice Upon a Time)
Upon seeing a vase of picked flowers, the Doctor would grab a few and smell them, holding them right up to his nose, (TV: Deep Breath, Death in Heaven, Heaven Sent) and, when brooding, would lean his face into his right hand as he looked downwards while pulling at his face. (TV: Into the Dalek, In the Forest of the Night, Dark Water, Death in Heaven, The Zygon Inversion, Oxygen)
Much like his fourth and ninth incarnations, the Twelfth Doctor would grin when he was pleased or amused, flashing his upper teeth as he smiled. (TV: Deep Breath, Listen, Time Heist, The Caretaker, Kill the Moon, Mummy on the Orient Express, Death in Heaven, Last Christmas, The Witch's Familiar, Under the Lake, The Girl Who Died, The Woman Who Lived, The Zygon Inversion, Face the Raven, Heaven Sent, The Husbands of River Song, The Return of Doctor Mysterio, The Pilot, Smile, Thin Ice, Knock Knock, Oxygen, The Pyramid at the End of the World, The Lie of the Land, Empress of Mars, The Eaters of Light, The Doctor Falls, Twice Upon a Time)
Something of a foodie, the Twelfth Doctor would snack upon food and drink during his adventures. (TV: Deep Breath, Robot of Sherwood, Listen, Death in Heaven, Heaven Sent, Hell Bent, The Return of Doctor Mysterio, Knock Knock, World Enough and Time, Twice Upon a Time) Unlike his first and eleventh incarnations, he had a tolerance for alcoholic beverages, (TV: Deep Breath, Mummy on the Orient Express) and, much like his third and eighth incarnations, took his tea with extra sugar, (TV: Death in Heaven) once having seven sugars in his tea. (PROSE: The Shining Man)
When not out adventuring, the Doctor could be found jotting down equations and theories on various chalkboards in the TARDIS console room, (TV: Robot of Sherwood, Listen) or on hard surfaces that could bear chalk markings. (TV: Deep Breath, The Doctor's Meditation) He also employed chalkboards as a form of non-verbal communication when using telepathy, (TV: Last Christmas) and in his lectures at St Luke's University. (TV: The Pilot, Oxygen)
He kept a spare sonic screwdriver in case something happened to his first. (PROSE: Big Bang Generation) Even after he discarded his old screwdriver for a pair of sonic sunglasses, (TV: The Magician's Apprentice, The Witch's Familiar) he still carried a model of his screwdriver to use on the odd occasion, (COMIC: The Ministry of Time, The Dragon Lord) after Clara returned one of his old spares to him. (COMIC: Clara Oswald and the School of Death) After receiving a new sonic screwdriver, he began to use them in conjunction with the sonic sunglasses. (TV: The Husbands of River Song, The Pyramid at the End of the World, Twice Upon a Time)
In his later life, the Twelfth Doctor spent time using Wi-Fi to pass the time, (TV: The Zygon Inversion, Smile, Twice Upon a Time) apparently looking up some embarrassing things (TV: Twice Upon a Time) as he has said multiple time not to look at his browser history. (TV: The Zygon Inversion, Smile) Another time, he suggested the subjects were beyond a human's comprehension. (TV: The Zygon Inversion) One of the subjects on his browser history was a series of cat photos that he and River Song had used to communicate, which he found somewhat embarrassing. (PROSE: Twice Upon a Time)
Highly observant, the Twelfth Doctor was able to point out certain individuals in a crowd, (TV: Deep Breath, The Magician's Apprentice, The Woman Who Lived, The Pilot) notice suspicious activity, (TV: Deep Breath, Dark Water, Smile, Thin Ice) and pick up on details that helped him unearth others' deceptions and plans. (TV: Listen, The Return of Doctor Mysterio, Thin Ice) However, when his attention was focused or he relied too much on his technology, certain things around him would go amiss. (TV: Dark Water, Sleep No More, Smile, Knock Knock, Twice Upon a Time) Being a Time Lord, the Doctor could also detect when a light shield aura was near him, (TV: The Caretaker) and was also able to fiddle with equipment and pilot the TARDIS while completely blind. (TV: Oxygen)
He was also able to make accurate deductions from observing his surroundings, identifying the Aristotle as a medical ship within seconds of being on board, (TV: Into the Dalek) noticing that Orestes Milton was a time traveller due to his choice of words, (PROSE: Silhouette) solving the riddle of the Foretold within sixty-six seconds, (TV: Mummy on the Orient Express) calculating a length of time by placing his finger in a cup of coffee, (TV: Under the Lake) and easily saw through the ruse of a conman's coin trick. (TV: Thin Ice) He could also correctly deduce others' histories and how they felt in their environments from sheer observation. (PROSE: Silhouette; TV: Mummy on the Orient Express)
As cunning as his seventh incarnation, the Doctor was able to spin a fatal outcome into an advantage, such as using Ross's death to help him, Clara, Journey Blue and Gretchen Carlisle escape Rusty's antibodies, (TV: Into the Dalek) using the deaths of Emile Moorhouse and Captain Quell as an opportunity to figure out a way to defeat the Foretold, (TV: Mummy on the Orient Express) and even using his own death to help him escape his confession dial. (TV: Heaven Sent) He was also able to organise a bank heist to save the Teller and its mate, even erasing his planning of the heist to guarantee success. (TV: Time Heist) Even later in his life, the Doctor was practical regarding death, and quick to "move on" when there was nothing he could do to save them. With no "time [for] outrage", when all hope seemed lost, he focused instantly on what he might yet control. (TV: Thin Ice)
Despite believing himself, in this incarnation, to not be well suited to the task, (PROSE: Silhouette) the Doctor proved to have a talent for holding a crowd's attention, (TV: The Pilot, Smile, Oxygen) having a strong sense of showmanship, (TV: The Magician's Apprentice, The Husbands of River Song) and quick comedic timing. (TV: The Woman Who Lived)
Similar to his ninth incarnation, the Twelfth Doctor was a capable fighter, managing to wrestle the Half-Face Man into a corner, (TV: Deep Breath) stun the General with a single punch to the face, (TV: Hell Bent) knock down Lord Sutcliffe by striking his face, (TV: Thin Ice) defeat several Voord with help from his tenth and eleventh incarnations, (COMIC: Four Doctors) and briefly hold his own against the Master. (TV: The Doctor Falls) He was also skilled in Venusian aikido, using it to disarm a distracted Robin Hood, (TV: Robot of Sherwood) defend himself from Abesse, (PROSE: The Blood Cell) and flip Jorj to the ground. (TV: World Enough and Time) Such prowess caused both the Half-Face Man and Kali to remark that the Doctor was "stronger than [he] look[ed]." (TV: Deep Breath; COMIC: The Swords of Kali)
Strong and durable, the Doctor was able to briefly support his own weight, (TV: Deep Breath, Listen) withstand several blows from Abesse, (PROSE: The Blood Cell) upstage Michael Smith by easily holding two baskets of rocks, (PROSE: Silhouette) force a door open with his shoulder, (PROSE: The Crawling Terror) smash up the TARDIS console with his bare hands in a grief-stricken rage, (TV: Death in Heaven) slam a door shut in a struggle with the Veil, (TV: Heaven Sent) and lift Bill from the Thames onto a ledge singlehandedly. (TV: Thin Ice) He was also capable of repeatedly striking a wall of Azbantium with his fists, even after breaking every bone in his hand, and was still able to use said hand to pull a lever afterwards. (TV: Heaven Sent) However, his durability was not absolute, with the Doctor being easily knocked to the ground by Nardole when he tried to volunteer to fight the light-eating locusts, (TV: The Eaters of Light) unable to escape the grip of a Mondasian Cyberman without assistance, and struck down when whacked by Missy's sonic umbrella. (TV: The Doctor Falls)
He also possessed lightning-fast reflexes, (PROSE: The Crawling Terror) notably being able to snatch the sonic screwdriver back from Spider's wrist before he was devoured, (TV: Thin Ice) and discreetly change the codes on the Master's computer in a matter of seconds without the Master or Missy noticing. (TV: The Doctor Falls) After being thrown out of Boat One in an explosion, the Doctor was able to skydive towards his descending TARDIS, even fighting against the wind currents to place the TARDIS key into the lock. (TV: Death in Heaven)
Like several of his predecessors, the Twelfth Doctor was a highly proficient swordsman, able to best Robin Hood in a duel using a spoon, (TV: Robot of Sherwood) take on Kali's three swords with a single blade, (COMIC: The Swords of Kali) and reportedly bested Bors' broadsword with a daffodil. (TV: The Magician's Apprentice) The Doctor even felt proficient enough in melee combat to willingly volunteer to hold back the light-eating locusts for as long as he lived. (TV: The Eaters of Light) He was also skilled with a Gunstick, shooting several Handmines from a distance while also avoiding hitting Davros. (TV: The Witch's Familiar)
Like his previous incarnations, the Twelfth Doctor also displayed telepathic abilities, being able to link his mind with Rusty to show him the beauty of the universe, (TV: Into the Dalek) clear the Governor's thoughts by tapping him on the head, telepathically communicate with Marianne Globus by placing his hands on her template, (PROSE: The Blood Cell) put Rupert Pink to sleep by placing his index finger on his forehead, editing his memories as he did so, (TV: Listen) put Clara through a telepathic scenario with the aid of a sleep patch, (TV: Dark Water) send a sedated Clara messages on blackboards by holding her hand, (TV: Last Christmas) establish a psychic link with a door to unlock it, (TV: Heaven Sent) and leave a message in Bill Potts's subconscious from a small distance. (TV: World Enough and Time) He was also prepared to wipe Bill's mind until she persuaded him not to. (TV: The Pilot)
The Doctor could not only perform eye-fixation hypnotism with verbal commands, but he claimed that, as a Time Lord, he could perform hypnosis that affected all the senses. (COMIC: Trust) He also threatened to use hypnotism to erase Danny Pink's memory of the Skovox Blitzer, (TV: The Caretaker) and was able to free several soldiers from the Monks' hypnotic control. (TV: The Lie of the Land)
Like his third incarnation, the Twelfth Doctor was a skilled inventor, being able to create an electron magnet and a sonic spoon in the Prison's craft workshop, (PROSE: The Blood Cell) a communication device to order a Skovox Blitzer to deactivate itself, (TV: The Caretaker) a 2Dis to combat the Boneless, (TV: Flatline) and rebuilding the TARDIS' radio into a clockwork squirrel. (TV: Under the Lake)
Despite denying being a doctor of medicine, (PROSE: Silhouette) the Doctor possessed at least a limited medical knowledge, being able to resuscitate Lafcardio with artificial resuscitation after Lafcardio's lungs were filled up with soot, with the Governor noting that the Doctor worked on Lafcardio like an expert. (PROSE: The Blood Cell) He was also able to perform an accurate post-mortem on Michael Smith, (PROSE: Silhouette) and Alan Travers, (PROSE: The Crawling Terror) and attach a Lothan prosthetic leg to Ram Singh. (TV: For Tonight We Might Die)
The Doctor also had a good sense of smell, which he used to assess his surroundings to deduce the time period he was in, (COMIC: The Swords of Kali) which he could also do by putting his finger in the wind. (TV: Before the Flood, Sleep No More) He could detect a plasmic discharge field on scent alone. (COMIC: Doorway to Hell)
The Twelfth Doctor was an excellent player of the electric guitar and could play with extreme confidence. (TV: The Pilot) Not only was he was able to play "Pretty Woman", (TV: The Magician's Apprentice) Beethoven's "fifth symphony", (TV: Before the Flood) "Wish You Were Here", (TV: The Woman Who Lived) and "Amazing Grace", (TV: The Zygon Invasion) he was also able to improvise his own tunes, (TV: The Magician's Apprentice, The Pyramid at the End of the World) such as one entitled "Clara". (TV: Hell Bent) He was proficient enough to join the Space Pirates on stage, (COMIC: The Twist) and keep up with Hattie Munroe when playing alongside her for enjoyment. (COMIC: Playing House)
Despite initially forgetting how to pilot his TARDIS due to post-regenerative trauma, (TV: The Time of the Doctor) the Doctor soon mastered his way around the TARDIS console, though admitted to Bill Potts that he mostly negotiated with the TARDIS when it came to "steer[ing]". (TV: Smile) When in control, the Doctor was able to save Journey Blue by piloting the TARDIS around her before her ship exploded, (TV: Into the Dalek) materialise around Clara while she was drifting in space, (TV: The Girl Who Died) and, with some difficulty, slowly fly the TARDIS above London. (TV: Face the Raven) He was also able to use the First Doctor's TARDIS control console with ease, (TV: Twice Upon a Time) and successfully returned Clara home in time for her dates, (TV: Listen, Time Heist, The Caretaker) though still made the occasional slip in timing and location. (TV: Deep Breath, Into the Dalek, Kill the Moon, Death in Heaven, Smile) He could also ride a horse, even when in a delirious post-regenerative state. (TV: Deep Breath, The Woman Who Lived)
The Twelfth Doctor retained his predecessor's ability to converse with other species, such as dinosaurs, horses, (TV: Deep Breath) donkeys, (PROSE: All the Empty Towers) and babies. (TV: The Girl Who Died) Though he claimed his knowledge of British Sign Language had been replaced with semaphore, he was still capable of signing, just not knowing what he had signed translated into. (TV: Under the Lake)
Believing himself to be a good magician, (TV: The Doctor's Meditation) the Doctor could hide objects in others' pockets, (PROSE: Silhouette) disappear when people were looking away, (TV: Listen, The Pilot) swipe things without detection, (TV: Listen, Thin Ice) make cups of tea appear out of thin air, (TV: The Witch's Familiar) perform hat tricks, (TV: Thin Ice) and also practised coin magic. (TV: The Doctor's Meditation) He was also able to swipe the General's sidearm before the General could regain his senses from being punched, (TV: Hell Bent) and carry a glass of water in his pockets on skill alone. (TV: The Return of Doctor Mysterio)
A credited escapologist, (TV: The Girl Who Died) the Doctor boasted at teaching Harry Houdini "everything he [knew]", (COMIC: The Swords of Kali) and was repeatedly able to escape from his cell at the Prison. (PROSE: The Blood Cell) He was also a talented gambler, winning $800,000 in less than an hour, which he credited to simple mathematics, (COMIC: Gangland) and dancer, with Clara noting that he could apply for Strictly Come Dancing. (COMIC: Trust) His performing abilities extended into acting, notably in how he fooled the Monks into believing that he wanted to assist them as a figurehead for their propaganda, even convincing Bill that was his agenda. (TV: The Lie of the Land)
Similar to his ninth incarnation, the Twelfth Doctor could slow down his perception of time; in this case by locking himself in a secure location in his mind, embodied as his TARDIS control room with his companion present, where he could take the time to reevaluate the predicament he was in to his companion and find a way out of it. (TV: Heaven Sent)
Similar to his tenth incarnation, the Twelfth Doctor had a measure of control over his regeneration energy, being able to summon a small amount for Davros, (TV: The Witch's Familiar) and fake a regeneration to fool Bill. (TV: The Lie of the Land) After being electrocuted by a Mondasian Cyberman, he managed to resist regenerating for two weeks, though was unable to walk properly without assistance for periods of time. Even as his regenerative process instinctively triggered itself after he was further damaged by another Mondasian Cyberman's energy blaster and the destruction of Floor 0507, the Doctor forced it back further despite the strain it placed on him, almost regenerating completely. (TV: The Doctor Falls) He managed to hold it back for several more hours until he was convinced to regenerate by the Testimony. (TV: Twice Upon a Time)
The Twelfth Doctor was a tall, thin-faced man with a tousled mop of silver-grey hair and intense eyes framed by unruly, expressive eyebrows. (PROSE: The Crawling Terror) He had a hooked nose, with big ears, (TV: The Time of the Doctor) and sharp silvery blue eyes. (TV: The Day of the Doctor) At some point, the Doctor appeared to have had his left earlobe pierced, and had visible scarring there by the time he extracted Clara from her timeline. (TV: Hell Bent) He was of a light build. (COMIC: Chime Time)
Most changed were his eyebrows, which went from "delicate" (TV: The Time of the Doctor) to extremely thick and furrowed. (TV: The Day of the Doctor) Startled by the change, the Doctor described them as "attack eyebrows", which could "take bottle tops off" and were "ready to secede and set up their own independent state of eyebrows". (TV: Deep Breath) He later considered his intimidating eyebrows as both a major contributor to his gravitas, (TV: Time Heist) and the reason many viewed him as a hostile. (COMIC: The Swords of Kali)
Physically, he resembled an older version of Lobus Caecilius, (TV: The Fires of Pompeii) with the Doctor himself noting he that had "seen [his] face somewhere before". (TV: Deep Breath) When he realised that he had seen his face when his tenth incarnation saved Caecilius's family from the destruction of Pompeii on Donna Noble's insistence, the Doctor concluded he subconsciously chose Caecilius' face to "hold [himself] to the mark" and remind him that he "save[d] people." (TV: The Girl Who Died)
Upon first seeing his reflection at Madame Vastra's house, the Doctor described it as "absolutely furious." Though he later admitted that his new face was "all right up until the eyebrows," he still did not like it. (TV: Deep Breath) The Doctor later described himself as a "distinguished gentleman with [a] twinkle in his eye." (COMIC: The Swords of Kali)
Tall and gaunt, he was called a "boney rascal" and a "desiccated man-crone" by Robin Hood, who also described the Doctor as being "pale as milk". (TV: Robot of Sherwood) Clara once described him as looking like a "grey-haired stick insect", (TV: Listen) with Shona McCullough described him as a "skeleton man". (TV: Last Christmas)
The Governor believed the Doctor had "a face for fury", and that it was "made up of storms" and "[boiled] away like a dying star". (PROSE: The Blood Cell) Clara also noted that the Doctor's face "always looked serious." (PROSE: Silhouette) Ross McNamara compared the Doctor's "craggy" face to "the surface of the Moon." (PROSE: Haunted)
Hair and grooming
The Twelfth Doctor's hair was a silvery shade of grey, (TV: The Time of the Doctor) which confused Clara, due to the Doctor only having "just got it". (TV: Deep Breath) His hair was originally short and combed down, (TV: The Time of the Doctor, Deep Breath) though occasionally styled into a coif. (TV: The Caretaker) However, he later let his hair grow out, and become curlier, (TV: Last Christmas, The Doctor's Meditation, Hell Bent, For Tonight We Might Die) but had it cut down by the time he met River on Mendorax Dellora. (TV: The Husbands of River Song)
After he left Darillium, (TV: Extremis) his hair had grown back to its old length. (TV: The Return of Doctor Mysterio, The Pilot) When his body began to regenerate, his regeneration energy caused his hair length to grow out immensely. (TV: The Doctor Falls, Twice Upon a Time)
Following his regeneration, the Doctor was placed into a Victorian nightshirt and slippers by the Paternoster Gang to help him rest. While investigating reports of spontaneous human combustion, the Doctor exchanged his old watch for a coat from a a vagabond, which he wore over his nightshirt. After infiltrating Mancini's Family Restaurant, the Doctor stole a Clockwork Droid's suit in order to masquerade as one to get close to the Half-Face Man. After having a chance to return to the TARDIS, though, the Doctor chose a new outfit for himself, (TV: Deep Breath) with the intention of "aiming for minimalism", but instead felt that he "came out with magician" after solidifying his wardrobe, (TV: Time Heist) though Clara commented his clothes made him look Victorian. (PROSE: Silhouette)
The Doctor initially donned a navy blue Crombie coat with crimson lining and a midnight blue cardigan, an ivory shirt with a pointing collar, indigo trousers, and black brogue boots. On his left hand ring finger, he had a pair of gold rings, a normal gold band and a second ring with a greenish amber setting that rested atop the first band, (TV: Deep Breath) which the Doctor considered to be a wedding ring, symbolising his marriage to River Song. (PROSE: Twice Upon a Time) Occasionally, the Doctor would replace his cardigan with a 5-button Palmer Waistcoat, with colours ranging in dark blue and plain black, (TV: Mummy on the Orient Express, Flatline) and change his dark blue trousers to black. (TV: Under the Lake) His socks were either decorated with cartoon animals (PROSE: The Blood Cell) or plain black, (TV: Heaven Sent) and his underpants reportedly had question marks. (TV: The Zygon Invasion)
Though his Crombie coat remained a constant staple of his appearance, he would wear them in a variety of colours and materials, with colours coming in navy blue, (TV: Deep Breath) black, (COMIC: The Eye of Torment) lapis blue, (COMIC: The Hyperion Empire) maroon, (COMIC: The Highgate Horror) black velvet, (TV: The Return of Doctor Mysterio) and worn-out grey. (TV: Extremis) The Doctor would also wear variations of his attire, switching from vested garments with a snowy shirt for a simple dress shirt on its own, coloured in burgundy, (TV: Robot of Sherwood) dark navy blue, (TV: Time Heist) or black with a white polka dot pattern. (TV: Kill the Moon) Towards the end of his life, he began keeping the cuffs of his sleeves unrolled. (TV: The Lie of the Land)
Other times, he would dispense with the shirts as well and don a black crew neck jumper (TV: Listen) with small star-shaped sparkles on the front that helped him see in the dark, (PROSE: Royal Blood) and later began wearing a zip up hoodie under his coat, with colours ranging in plain black, (TV: Last Christmas) ocean green, (TV: Under the Lake) and marine blue. (TV: The Woman Who Lived) Under his jumper, he wore a white, (TV: Listen) red, (TV: The Woman Who Lived) or grey T-shirt. (COMIC: Time and PR in Space) On one occasion, he wore a burgundy ladder jumper. (TV: The Return of Doctor Mysterio)
In his "rock star" image,[source needed] the Doctor continued to wear his hoodie under his Crombie coat, but replaced his jumper with an ivory T-shirt and a pair of baggy plaid trousers similar in style to those of his second incarnation, either in a light grey colour, a dark blue design with a white plaid pattern, a dark blue tartan pattern with crimson stripes, (TV: The Doctor's Meditation, The Girl Who Died, The Woman Who Lived) or a bottle green colour. (COMIC: The Ministry of Time) His vest wear included a dusty pink Henley top underneath a Misty Mountain T-shirt, (TV: The Doctor's Meditation) a Negative Flower T-shirt, (TV: The Girl Who Died) a plain white T-shirt, (COMIC: The Ministry of Time) and a black T-shirt with a shark on it. (TV: Face the Raven)
During his time at St Luke's University, the Doctor began wearing a black velvet frock coat with a cornflower blue lining, while the rest of the his outfit came with many variations. Accompanying the frock coat would be a puce, dark green or black hoodie, (TV: The Pilot, The Eaters of Light) a ocean green ladder, black distressed or blue paint splatter jumper, (TV: The Pilot, The Eaters of Light) a white shirt or longline burgundy, blue or black t-shirt, (TV: The Pilot, The Eaters of Light) and a blue or black waistcoat with notched lapels and brown buttons. (TV: The Pilot) On one occasion, he dispensed with the waistcoat and wore a simple scarlet dress shirt. (TV: The Pyramid at the End of the World)
When going into "deep cover" as Coal Hill School's temporary caretaker, the Doctor donned an ocher brown warehouse coat over his black crew neck jumper. (TV: The Caretaker) The Doctor was photographed wearing the same outfit while brandishing a mop at some point before 5 March 2005. (PROSE: Rose)
For formal wear, the Doctor would don a black double-breasted suit jacket, black trousers and low-rising waistcoat, his black brogue boots, a white dress shirt and a black cravat tie. (TV: Mummy on the Orient Express, The Husbands of River Song)
When Zip Betterblast gave him a "re-design" for his TV appearance, the Doctor received blue jeans, a cap with a "DW" logo, and yellow sleeveless V-neck top with a palm tree island image on it. (COMIC: Time and PR in Space)
After returning to Gallifrey, the Doctor discarded his waistcoat and velvet Crombie coat in favour of a black overcoat, a white collarless formal shirt, a black shawl lapel waistcoat, dark trousers and black brogue boots. He later resumed wearing his Crombie coat when he returned to his TARDIS; it is not the same outfit he wore on Gallifrey, however, but a replacement gifted to him by Clara Oswald at the same time she wrote her farewell message on his blackboard. (TV: Hell Bent)
When the Doctor took Bill Potts to the frost fair of 1814, he wore his velvet frockcoat, but favoured more Regency era clothing in the form of navy trousers, a royal blue brocade waistcoat, a midnight blue cravat, a white shirt, black gloves and a navy top hat that he swapped later for a black one. (TV: Thin Ice)
Behind the scenes
Information from invalid sources
- Promotional material for Doctor Who Experience mentions that the green amber stone on the Twelfth Doctor's ring was "allegedly" collected on the planet Raxacoricofallapatorius.
- In DWM 477, showrunner Steven Moffat jokingly answered one fan's question on what colour the Doctor's kidneys now were, after he had complained about their colour, as "Froon", a colour which only the Doctor could see.
- Writing in DWM 495, Moffat confirmed that the photo-realistic painting of Clara seen during Heaven Sent was painted by the Doctor himself. Capaldi himself is a trained artist, although his style is more on the caricature side.
- According to the Doctor Who The Official Annual 2018, which is not accepted as a valid source for in-universe articles on this wiki, the Doctor and River had a home on Darillium during their final night; their address was "Flat 40, Singing Towers View, Darillium".
- In the twentieth anniversary edition of Who Killed Kennedy by David Bishop, an epilogue was added in which James Stevens contacts the Twelfth Doctor and convinces him to alter the coordinates of the Master's Time Ring so that he can travel to 11 August 1971 and prevent Francis Cleary from killing his former companion Dodo Chaplet.
- Capaldi was the second actor, after Sixth Doctor actor Colin Baker, to have played an on-screen character in Doctor Who before being cast as the Doctor, having played Lobus Caecilius in The Fires of Pompeii and John Frobisher in Torchwood: Children of Earth. However, if one counts David Tennant's appearances in various Big Finish audios and Scream of the Shalka prior to his casting as the Tenth Doctor, Capaldi is actually the third actor to have appeared in Who-media prior to taking on the role.
Peter Capaldi's age
- Cast at 55-years-old, Peter Capaldi was the oldest actor to regularly portray the Doctor since First Doctor actor William Hartnell, who was a few months Capaldi's junior. War Doctor actor John Hurt, however, remains the oldest actor to portray a new incarnation of the Doctor upon debuting, at 73-years-old.
- Peter Capaldi wanted to wear his wedding ring as part of the Doctor's attire, and requested a prop to disguise it. He was given an amber ring with a gemstone that fitted over the top of his original band. It was revealed in the Twice Upon a Time novelisation that the ring was the Doctor's wedding ring from his marriage to River Song.
- His costume was revealed in DWM 470 and online earlier than planned to preempt a tabloid scoop.[source needed]
- Like the War Doctor and the Ninth Doctor before him, the Twelfth Doctor debuted in a television story before his regeneration from his predecessor was screened.
- Peter Capaldi pierced his left ear earlier in life and the scar from his piecing was visible during close-ups of his face in Hell Bent. This is the second time the Doctor has sported noticeable body modification from the previous life of his actor; Jon Pertwee's arm tattoo from his Royal Navy days was visible in a scene in Spearhead from Space.
- In several series 9 episodes, most notably Heaven Sent, the Doctor displays a slight limp, because Capaldi had injured his knee early in filming of the season, and underwent surgery to repair the knee late in 2015. As Capaldi later explained, "We realised what it is: you run down these corridors and you reach the end and then you spin to make sure you get a nice close-up. You spin on that leg and you put tension on that knee."
