Tenth Doctor

Benefiting from the healing undergone by his predecessor, the Tenth Doctor possessed an outgoing, lively and genial demeanour that hid his underlying guilt, but it was still present and would appear if the Doctor was overwhelmed.

For most of his life, the Doctor was able to successfully project a convivial and even frivolous front. However, when he had to engage in conflict, the Doctor's energies would shift to reveal a fiercely protective man who resolutely guarded what he held dear, and who could be viciously unforgiving to the forces that dared menace them.

He was unique in that he was the only incarnation of the Doctor who chose to abort one of his regenerations, channelling the energy into his spare hand without changing his appearance, something his successor would attribute to suffering "vanity issues at the time".

Many of his relationships with companions were shaped, to one degree or another, by romance; he seemed to genuinely love his first companion, Rose Tyler, as the person who helped heal some of the scars of the Time War, was completely oblivious to Martha Jones' obvious affections toward him, and insisted upon a platonic relationship with Donna Noble. The departure of each of these companions marked periods in his life where he would abstain from having companions at all, and on one occasion he even stopped having adventures or leaving the TARDIS, with little more than a cat for company.

When travelling without companions, the weight of being the last Time Lord became much more pronounced. If prodded too much, he would erupt in an often righteous sense of fury. Indeed, the Tenth Doctor was described by the Moment as "the man who regrets". The fact that he was instantly able to recall the number of Gallifreyan children that he believed were killed at the end the war indicated just how keenly he continually felt those horrendous memories.

He met his eventual end after he absorbed a huge quantity of nuclear radiation whilst saving the life of Donna Noble's grandfather, Wilfred Mott. Delaying the process to visit all of his companions, the Doctor finally regenerated in the TARDIS, causing a huge amount of damage due to delaying the regeneration for as long as he did, and leaving his successor crashing straight for Earth.

The Doctor slept through much of the ongoing invasion by the Sycorax. When the TARDIS was taken aboard a Sycorax spaceship on Christmas morning, he awoke with the help of some tea that seeped into a component of the TARDIS, (TV: The Christmas Invasion) alongside regeneration energy which he seeped from his third incarnation, who had arrived in Jackie's apartment moments before. (PROSE: The Christmas Inversion) Stopping the Sycorax leader's blood control of humanity, the Doctor challenged him to a duel over the fate of Earth.

Luckily, Lerox, a kind-hearted Sontaran, convinced Thanatos that the Sontarans were worth sparing. The Doctor left Lerox with the idea of founding a new Sontaran rig called "The Hope of Sontar", hopeful that other Sontarans could learn from Lerox's compassion. (COMIC: The Betrothal of Sontar)

When the TARDIS jumped a time track with Rose inside, the Doctor was trapped on the Powell Estate for a week, waiting for its return.

He encountered her again that night, as like him she'd returned to the school at night to investigate, and revealed his identity. After repairing K9 Mark III and making amends with her, he learned that Krillitane oil was being added to the school dinners to boost the children's intelligence. Rose confronted him about Sarah Jane forcing him to confess that she could spend the rest of her life with him, but he couldn't with her. He defied this as "the curse of the Time Lords", unknowingly revealing himself to the Krillitanes' leader, Brother Lassar, who was spying on them.

The next day he confronted Lassar at the school and warned him, however the Krillitane was confident he'd join forces with them one he worked out what they were trying to achieve. Together with Sarah and Rose He found the Krillitanes were using the children's minds to solve the Skasis Paradigm. Lassar interrupted and tempted him with an alliance, claiming he could use the Paradigm to restore fallen civilisations, including his own people. Sarah talked him out of it and Lassar ordered his brothers to pursue them. K9 sacrificed himself to blow up the Krillitanes with their oil, destroying the school, which Mieky had emptied, in the process.

The Doctor asked Sarah Jane to rejoin him on his travels, but she declined, instead suggesting that the Doctor allow Mickey to accompany him and Rose on their travels, as he was finally ready to see the universe. Before they departed, the Doctor also built a new K9 as parting gift for Sarah Jane, giving it all the memories of the previous model. (TV: School Reunion)

Adventures with Rose and Mickey
With Mickey now aboard, The TARDIS landed on the a spaceship in the 51st century, where the Doctor and his companions found that the crewmembers' organs were used as "parts" by the repair droids after the ship had been damaged. The droids created time windows to find Reinette, the Madame de Pompadour, and complete repairs.

While investigating, the Doctor travelled throughout Reinette's life through use of the time windows, fighting the droids throughout 18th century France and developing a romantic relationship with Reinette. After Rose and Mickey wandered off, the Doctor found a horse that had wandered through the window onto the ship, naming him Arthur. (TV: The Girl in the Fireplace) While talking to Arthur, the Doctor discovered a portal through which briefly came the hand of a humanoid. (COMIC: The Road To...) When the droids came to harvest Madame de Pompadour, the Doctor, on horseback, broke through a time window to the court of Versailles in 1758, shattering the connection to the ship and stranding himself and the droids from the ship, causing the droids to deactivate from a lack of purpose.

Initially resigning himself to living with Reinette, the Doctor found a link back to the ship and his TARDIS through her old fireplace. The Doctor tried going back through the fireplace so that he could take Reinette to see the universe, but the loose connection to the time window meant she had already died when he returned. After reading a heartfelt letter she had left him, the Doctor was left devastated. (TV: The Girl in the Fireplace)

After Rose became infected with an Iagnon grub, the Doctor sent Rose into a dream where he was dating her mother and Mickey had an Amazonian girlfriend so that her jealously could drive the creature out of her body. (COMIC: The Green-Eyed Monster)

Whilst travelling through time, the Doctor, Rose and Mickey fell through a crack in time, ending up on a parallel Earth more technologically advanced than their Earth. While the TARDIS had died upon landing in the alternate universe, the Doctor managed to power a surviving piece of the TARDIS, but it required a twenty-four hour recharging cycle before the TARDIS could restore itself, giving the Doctor, Rose and Mickey time to explore the alternate Earth.

When Rose found her father was alive on the parallel world, the Doctor cautioned her against making contact. While Mickey searched for the parallel version of his grandmother, the Doctor gave in to Rose's request to attend the birthday party of her parallel mother. At the party, the Doctor was discovered a parallel version of the Cybermen had been created, and could only stand witness as they crashed the party, and killed the guests inside. (TV: Rise of the Cybermen)

Escaping, the Doctor allied himself with the Preachers, and organised a break in into Cybus Industries Factory, where mass conversions were beginning. He paired up with Miss Moore to use the tunnels and discovered the emotional inhibitor was key to the Cybermen. She was killed and he was taken to the creator of the Cybermen, John Lumic, for analysis due to his alien anatomy. He discovered Lumic had already been converted into the Cyber-Controller. The Doctor bought time by trading philosophical ideas with Lumic while subtly telling Mickey and Jake Simmonds to hack the Lumic family database to find the cancellation code to the Cybermen's emotional inhibitors. Mickey texted Rose the code, and the Doctor connected the phone with the code to deactivate the Cybermen's inhibitors, causing them to explode, along with Cybus Industries.

When it came time to leave, Mickey chose to stay behind to fight Cybermen worldwide, both because he had witnessed his counterpart's death, and because he didn't fit in with the Doctor and Rose's close relationship. The Doctor and Rose honoured Mickey's wishes and returned to their universe, where they visited Jackie at the Powell Estate. (TV: The Age of Steel)

Fighting off the infection himself, the Doctor stopped the Macrobes from using his Time Lord mind and his TARDIS to spread the infection across time and space. His victory was short-lived when he found the Chosen Scholars had also disappeared. (COMIC: The Macrobe Menace)

Using a book from the Rago university, the Doctor and Rose next ended up on Gameworld Gamma, where they discovered a human colony was being hunted for sport by royalty, headed by Platform guests Mr and Mrs Pakoo. He closed down the games and sent the humans back to Earth. He found the Pakoos had been taken, but he knew that, unlike the others, they had been taken to attract his attention. (COMIC: The Hunt of Doom)

After Rose disappeared, the Doctor finally learned the truth: the vengeful brother of the Moxx of Balhoon, the Elth of Balhoon, had been kidnapping all the guests as he felt they had not done enough to prevent his death on Platform One. Recognising his grief, the Doctor released all the kidnapped guests and persuaded them to help Elth rather than condemn him. (COMIC: Reunion of Fear)

Further adventures with Rose
While considering purchasing a pet for the TARDIS, the Doctor and Rose visited Paws 'N' Claws, only to discover that the pet store was being run by peaceful Cybermen who had settled into the consumer environment.

When Grandma Connolly was taken away by police, he pursued and met Detective Inspector Bishop, who accepted his help. After Rose was found with her face taken, the Doctor was infuriated.

They discovered that Mr Magpie‘s television sets were the commin denominator in the cases and went to confront him. They learnt the Wire was using the coronation to feed on the electrical activity of the brain, "taking people's faces [and] their essences". After nearly being consumed himself, the Doctor pursued the Wire and Magpie up Alexandra Palace and climbed after them to prevent the Wire from becoming manifest again by converting the "big transmitter" into a receiver of all of the faces of the people watching the coronation.

The visual of Paxxo disappeared, and the Doctor realised this was a trap set up by Hasval using a hologram projector, and there was no TV show at all. Rose pointed the hologram projector at the Doctor, and unwittingly created hundreds of duplicated projections of the Doctor.

(PROSE: No Fun at the Fair)

The Doctor and Rose came back to Earth, in Norwich, when Jackie called them to fight against the apparent invasion of the Zaross, a species neither the Doctor or the TARDIS recognised.

Facing the Beast
The Doctor and Rose landed inside Sanctuary Base 6 on Krop Tor, a planet that was in perpetual orbit around the black hole K37 Gem 5, and lost the TARDIS following an earthquake. The crew of Sanctuary Base 6, having come to Krop Tor to discover the source of power emanating from the planet's core which allowed the planet to orbit the black hole, refused to divert their drill to collect the TARDIS. This forced the Doctor and Rose to contemplate a future settling down. The Beast began terrorising the explorers and possessing their servants, the Ood. The Doctor and the science officer of Sanctuary Base 6, Ida Scott, descended into the core of the planet and discovered a pit which had started opening. (TV: The Impossible Planet)

When nothing emerged from the pit, the Doctor speculated the prison was open but not the cell and decided they should withdraw. However the transport tube back to the surface was rendered unusable by the Ood cutting the cable, so the Doctor decided to use the cable to descend into the pit. Inside, he came face-to-face with the Beast and tried conversing, though its consciousness had already escaped to the expedition's archaeologist, Toby Zed. Realising the Beast's jailers thought of the Beast's escape, the Doctor shattered the jar keeping the planet orbiting the black hole, believing Rose would find a way to survive. At the same time, Toby was ejected from the Sanctuary Base 6 rocket by Rose. Though willing to "go along for the ride", the Doctor discovered his TARDIS by accident; he saved Ida, but didn't have enough time to rescue any of the Ood. Towing the rocket safely away from the black hole, the Doctor "swapped passengers" and resumed his travels with Rose. (TV: The Satan Pit)

Final adventures with Rose
The Doctor and Rose pursued a Hoix, during which the Doctor briefly encountered an adult Elton Pope, but Elton ran away as the Doctor and Rose left in the TARDIS. (TV: Love & Monsters)

He unwittingly saved Elton from being absorbed by Victor Kennedy after arriving. Kennedy tried threatening Elton's life so he could take over the TARDIS, but the Doctor refused. He told Kennedy that the members of LINDA, who had already been absorbed, would have had something to say about absorbing Elton. They pulled at Kennedy's stomach, causing him to drop his cane. Elton broke the cane's limitation field that was preventing the ground from absorbing him. Though he couldn't save the others' lives, the Doctor brought the consciousness of Ursula Blake back, but stuck as a face on piece of concrete. He then told Elton the truth about his mother's death. (TV: Love & Monsters)

After defeating Professor Janus in Victorian London, the Doctor and Rose, posing as detectives, uncovered a cult of vampires led by Count Dracula of Wallachia.

Proving to Rose that his adventures were not completely dangerous, the Doctor re-installed a randomiser into the TARDIS, which transported him and Rose to the thirteenth moon of the thirteenth planet in the Thirteenth Galaxy, on the thirteenth day of the thirteenth year of the 13th century. There, they met the Triskaidekaphobes, the unluckiest species in creation. The Doctor discovered Bob Kreesus had been kidnapping Triskaidekaphobes and stealing their fortune. After returning the Triskaidekaphobes' luck, the Doctor confronted Kreesus on a cliff, where Kreesus accidentally fell to his death. (COMIC: Triskaidekaphobia) They then stopped an Arcadian arms dealer from using sentient bombs called Smart Bombs to bomb a planet by stranding him on the planet he was hired to obliterate.

The Doctor and Rose went to 2012 to see the Olympics, where they met Chloe Webber, a girl who had been possessed by a lone Isolus, who was trapping other children from her street in drawings to give the Isolus company. Despite attempting to help the Isolus, the Doctor was trapped in a drawing, along with the TARDIS. (TV: Fear Her) Inside the drawing, the Doctor fought scribble creatures, saved Ginger and Stuart (GAME: Art Attack) and was able to draw a depiction of the Olympic torch and pointed at it to aid Rose. Once Rose tossed the Isolus' pod into the Olympic flame to recharge it, the Doctor and the children were freed from the drawing. As the torch bearer had been injured by the pod, the Doctor took his place, lighting the Olympic flame himself. Reuniting with Rose, the Doctor warned her that he felt a "storm" coming when she said that no-one would ever separate them. (TV: Fear Her)

In the city of Vanezia, the Doctor and Rose allied with future musical hit Frederico Gobbo to investigate an opera house that shouldn't have been located in Vanezia. They found the owner, Magrillo, was draining people's energy to power a machine called the Orchestra, which transmitted mathematic equations into space. The Doctor overloaded the machine by getting Fredrick to sing a bad song, destroying it and killing Magrillo. After this, he discovered the Orchestra had turned Fredrick into the musical talent he was destined to become. (COMIC: Opera of Doom!)

The Doctor and Rose later came under attack from skeletons in a graveyard. Seeking solace at Ivy Hensons home, the Doctor discovered the skeletons had been animated to act as repair men by a terraforming device that had fell to Earth. (PROSE: Gravestone House) They then visited an art gallery on the Moon, where they discovered an artist had used a soul extractor to improve his painting and had ended up turning it into an intelligent creature. (PROSE: Untitled)

The Doctor became intrigued by the disappearance of Lower Downham, travelling there with Rose to 1962 to unravel the mystery. He discovered the village had been evacuated by the Viyrans, who had followed a dangerous chemical weapon to Earth. The chemical couldn't be neutralised, so the Doctor and Rose left the Viyrans to place a perceptual barrier across the entire village. (PROSE: No One Died)

The Doctor and Rose also visited a rocky, barren planet and watched giant creatures fly past, where Rose expressed that she would stay with the Doctor forever. (TV: Army of Ghosts)

The Doctor risked a visit to Sunset Strip, a lawless planet populated by bounty hunters, gangsters and mobs. He discovered he owed a million credits to Mr Lippizzaner, leader of the notorious Trigger Brothers. Although there was a large bounty on his head, the Doctor stopped the Triggers and their business rival, Don Corpulone, from finding "the Bird", a Glitterbird egg from a rare robot species whose were studded with diamonds. He installed detective robots to arrest the two mob families and establish law and order on the planet. (COMIC: Gangster's Paradise)

The Doctor treated Rose to a visit to Paris. However, they discovered that they had become trapped in the Facade, a computer that enhanced people's perception of "Perfect Paris".

Taking Rose for a steak meal, the Doctor accidentally transported them to Phijax IV, where they were forced to fight as entertainment for the Glutonoid, who threatened to eat Rose if they didn't. The Doctor injected the Glutonoid with TARDIS pills, which destroyed it. (COMIC: The Glutonoid Menace)

The Battle of Canary Wharf
Returning to the Powell Estate, the Doctor and Rose found humanity was being visited by beings believed to be ghosts of their loved ones. The Doctor tracked the signal to Torchwood Tower in Canary Wharf and, along with accidental stowaway Jackie, was taken prisoner by the leader of the Torchwood Institute, Yvonne Hartman, while Rose remained in the TARDIS as it was taken away. The Doctor strongly opposed their use of "ghost shifts" for a power source, as it was ripping a hole between parallel worlds which increased in size with every iteration, and convinced Yvonne to pause the experiments. The original tear was caused by a Void Ship. Two computer technicians, secretly under the control of Cybermen, restarted the ghost shift. The ghosts, who were actually Cybermen, came from the parallel world where the Doctor and Rose had left Mickey. As the Cybermen invaded Earth, the void ship opened, revealing a group of Daleks called the Cult of Skaro (TV: Army of Ghosts) with a Genesis Ark, a Time Lord prison ship containing millions of Daleks.

As the Daleks and Cybermen waged war with each other, the Doctor was transported back to the Cybermen's original universe, where he reunited with Pete Tyler at the other universe's Torchwood, where the People's Republic took over when the Preachers knew what it was doing. With the Preachers, the Doctor returned to his universe. With the help of a short alliance between the Cybermen and the Preachers, the Doctor rescued Rose and Mickey, who had found his way back to N-Space, from their imprisonment by the Cult of Skaro. In the confusion, Mickey accidentally touched the Genesis Ark, opening it and releasing millions of imprisoned Daleks. The group then saved Jackie from being upgraded by the Cybermen.

To defeat his warring enemies, the Doctor needed to open the Void; doing so would suck anything covered in "Void stuff" into it and seal off the two universes for good. Realising that Rose was also covered in Void energy, the Doctor sent her, along with Mickey, Pete, Jackie and the other Preachers, back to "Pete's World", where they would be safe, but Rose refused to leave the Doctor and returned, knowing she would never see her family again. Together, the Doctor and Rose opened the Void and the Daleks and Cybermen were sucked in. The plan initially went smoothly, until Rose's lever malfunctioned, threatening to halt the operation. Rose secured the lever, but couldn't keep her grip and began to fall into the Void. She was saved at the last second by Pete and taken back across to the other universe, separating her from the Doctor. (TV: Doomsday)

Adventuring alone
Journeying on without Rose, the Doctor nearly fell off a cliff on the planet Hondran, but was saved by Kara McGravy. After finding Hondran overrun by the Untra, the Doctor managed to lure them to the edge of a cliff, and allowed carnivorous plants to eat them. (COMIC: The Hunters)

Still devastated, the Doctor met Rose one last time at Bad Wolf Bay in the Norway of Pete's World. He was able to project a hologram of himself through the last crack between the universes by parking the TARDIS in orbit around a supernova to gain enough power to say goodbye. Rose finally told the Doctor that she loved him, but before he could confess his response, the connection was lost. The Doctor was left alone and teary-eyed, until a woman in a wedding dress suddenly appeared inside the TARDIS. (TV: Doomsday) The woman, Donna Noble, had been at her wedding to Lance Bennett, (TV: The Runaway Bride) unexpectedly finding herself spirited away to the TARDIS without explanation. She loudly protested at where she had ended up, putting the Doctor in a state of bafflement. (TV: Doomsday)

While trying to return Donna to the ceremony on Christmas Eve 2007, the Doctor chased a taxi across the motorway in the TARDIS as Donna was kidnapped by the Roboform. Successful in saving her, he returned her to her wedding reception, where the Roboform attacked with bombs disguised as Christmas baubles. The Doctor destroyed the attack force and went with Donna and Lance to H.C. Clements, which had a basement leading to a secret Torchwood base underneath the Thames. There, the Doctor and Donna discovered that Lance was working for the Empress of the Racnoss, and planned on using Donna as an incubator for Huon particles needed to revive the other Racnoss in stasis at the Earth's core; Donna had appeared in the TARDIS because of a magnet-like pull between the Huon particles within her and those within the TARDIS.

Using that magnetic pull to bring the TARDIS to him, the Doctor and Donna travelled back in time to witness the Racnoss' presence at the Earth's creation. Forced back to 2007 by Lance being force-fed Huon particles in Donna's place, which also resulted in him being fed to the Racnoss offspring through a hole dug by Torchwood, waking them. After the Empress failed to take his offer to leave Earth, the Doctor drowned the Racnoss offspring by flooding the Torchwood base on top of the hole with the River Thames. He ignored the Empress' screams for mercy, only leaving at Donna's request. When the Empress tried attacking London with her Webstar in retaliation, the British military destroyed her along with it. Taking Donna home, the Doctor asked her to join him in the TARDIS, but she declined because his execution of the Racnoss had scared her. (TV: The Runaway Bride)

Following a distress signal, the Doctor began investigating disappearances in a small English village. Aided by Brynn, the last child in the village, he discovered a dying crashed sentient spaceship was abducting children to keep itself entertained with their imaginations. Brynn allowed the ship to feast on his imagination to "finish the story", allowing it to die happily and releasing all the children it had taken. (PROSE: Once Upon a Time)

The Doctor discovered a Floof, a species with the ability to hide in plain sight, had been stalking a man called Tom. Befriending Tom, the Doctor realised the Floof had developed a psychic link with Tom and was unwilling to let him go, killing Tom's wife. Enraged, the Doctor punished the Floof by separating it from Tom, condemning it to eternal loneliness. (PROSE: Corner of the Eye)

Attempting to see central London's Christmas lights, the Doctor accidentally landed the TARDIS in Daniel Francis Thompson's bedroom. Daniel made his way into the TARDIS and meddled with the controls, transporting the time machine to Belgium in 1914, where they witnessed a German and British football match. After visiting various Christmas periods in Earth's history, the Doctor returned Daniel home. (PROSE: Deep and Dreamless Sleep)

The Doctor gave Grayla a lift away from her home planet, Grått, but decided not to take her on as a companion, feeling that she had her own path to take without his help. (COMIC: The Whispering Gallery)

The Doctor took a break from his travels on the Earth colony world, Centuria. His holiday was cut short when he discovered an army of Cybermen had been rebuilt from the Battle of Canary Wharf. Taken prisoner and unable to stop the Cybermen's takeover of Centuria, the Doctor met Jayne Kadett, an investigator. He and Jayne managed to destroy the Cybermen at the heart of the Centuria invasion. They discovered the Cybermen had been rebuilding their army across the universe, so the Doctor took Jayne with him to track them down and destroy them. (COMIC: The Power of the Cybermen)

Following the Cybermen's signal, the Doctor flew an airship across the continent of Azlon, which had now become a gigantic Cyber-conversion factory. The Doctor and Jayne destroyed the factory and found a map that brought them closer to destroying the heart of the new Cybermen Empire. (COMIC: Drones of Doom) Taken prisoner below the arctic lands of Centuria, the Doctor and Jayne met Homaj, a half-cybernised drone. After battling the Ice Snakes and cyber-dogs, the Doctor and Jayne used explosives to destroy the Cybermen's base. Homaj sacrificed himself, and the Doctor and Jayne discovered the key to stopping the Cybermen was by destroying Centuria Central. (COMIC: Enemy Mine)

When Jayne became frozen in time, the Doctor set off to Centuria Central alone, becoming a fugitive. He infiltrated the base and destroyed the stasis machine, which had a mental link to the Cybermen. As a result, Cybermen across the galaxy were destroyed. With the galaxy protected, the Doctor asked Jayne to travel with him, but she declined. (COMIC: Time of the Cybermen)

Travelling alone, the Doctor visited Croxton Hall and, alongside waitress Daisy White, battled the ghosts of Lord and Lady Tubbs and their houseguests. He used the Ancient Horologe, a timepiece used to measure the passage of time across the dimensions, to transform all the ghosts into humans. After the house was restored to normal, the Doctor attended the Tubbs wedding anniversary. (COMIC: 13 O'Clock)

Arriving on the Space Station Alpha in the 36th century, the Doctor met a snag finder called Jimmy and his Welding Bot X-5, who went by the name of "Bert". The Doctor discovered the Klytode had scrambled Bert's circuits and was intending to launch a cobalt bomb on the station, which would cause the station to crash to Earth and destroy it. The Doctor saved Bert, tricked the Klytode into destroying his own planet, and had him arrested. (COMIC: The Snag Finders)

Soon after, the Doctor stopped off at a 12th century English village at the time of the Black Death. He discovered the Zeerover virus had turned the villagers into zombies. Making a deal with the Zeerovers, the Doctor cured the villagers. (COMIC: Plague Panic)

Reunion with the Brigadier
The Doctor visited the Slough of the Disjointed Planets, a space populated by warlike races renowned for their brutal conflicts. There, he encountered the dying War Keeper, the ancient controller of the population of the Disjointed Planets. To find a worthy successor, the War Keeper scanned the Doctor's mind for the identity and location of the greatest leader in the cosmos. He chose Brigadier Alistair Gordon Lethbridge-Stewart, now retired and in his late seventies, who refused to accept the War Keeper's demands. As an alternative, the War Keeper chose Mike Yates, but accidentally summoned another man with the same name.

Rivals of the dying War Keeper infiltrated his helpers before his death and passed onto Yates the Keeper's control device, the Warkeeper's Crown. With the weak-minded Yates under the control of the Crown and the many forces of the Disjointed Planets, the deceased War Keeper's rivals planned to control the conflicts. The controlled Yates transported himself back to Earth, along with many Orcs, Hawks and other creatures.

The Doctor and the Brigadier, with an army of Brigadier clones the Doctor created with technology at the Slough, returned to the Earth to defeat the demon hordes and free Yates from the Crown's control. With the danger passed, the Doctor and the Brigadier re-lived their old glories and said their goodbyes, although the Brigadier expected to see the Doctor again. (COMIC: The Warkeeper's Crown)

Meeting Martha
While investigating a set of plasma coils in 2008 London, the Doctor checked himself into Royal Hope Hospital, where he met medical student Martha Jones. The hospital was H₂O scooped onto the Moon by the Judoon, who were hunting the Plasmavore murderer Florence Finnegan. Pretending to be human, the Doctor tricked Finnegan into drinking some of his blood, which she assimilated into her system, and the Judoon executed her after identifying her as a non-human. Martha revived the Doctor, and the hospital was returned to Earth. After leaving the hospital, the Doctor tracked down Martha at a family gathering to offer her one trip in time as a way of expressing gratitude for her assistance. (TV: Smith and Jones)

The Doctor took Martha to 1599 London to meet William Shakespeare. Learning the lost play, Love's Labour's Won, was to be performed, the Doctor decided to investigate why it vanished. He discovered the Carrionites had the Globe Theatre constructed to their design in order to use a hidden incantation in the script to free the rest of their kind from the Deep Darkness. Despite succeeding, their incantation was reversed by one improvised by Shakespeare, trapping them and all copies of the play in the Darkness. As it risked freeing them, the Doctor advised Shakespeare not to rewrite the play. While bidding Shakespeare goodbye, Queen Elizabeth I arrived and ordered her men to kill the Doctor, declaring him her sworn enemy, much to Martha's confusion and the Doctor's amusement. (TV: The Shakespeare Code)

Fleeing the Queen's men, the Doctor decided to stretch the one trip agreement with Martha to include a trip to the future. Returning to New Earth in 5,000,000,053, Martha was kidnapped by a couple wishing to use the New New York Motorway's fast lane. Searching for her, the Doctor discovered the city had been plagued and the population had become trapped on the motorway for their own safety. Novice Hame took the Doctor to what was left of the Senate to help the Face of Boe open the Motorway. Martha and the population were freed from being attacked by the Macra, who lived in the filthy air below the cars. After the Face of Boe sacrificed his own life to power the doors keeping the motorway shut, he uttered his secret to the Doctor: "You are not alone". As the city sang in celebration of their freedom, the Doctor told Martha of the Last Great Time War. (TV: Gridlock)

Adam Mitchell's revenge
The Doctor took Martha to the Griffith Observatory in Los Angeles to show her the last residual image of Gallifrey via a telescope, and the pair got involved in the production of a movie that was being sabotaged by the Dominators. After the Doctor defeated the Dominators' plot, Martha was kidnapped by Adam Mitchell, (COMIC: Quiet on the Set) the Doctor sent a message to Frobisher to infiltrate Adam's base. (COMIC: Façades)

Following a chronal trail left by the Eleventh Doctor, the Tenth Doctor joined his other incarnations as they stormed Adam's fortress in Limbo to save their friends from Adam and, merging their TARDISes together to gain them entry. Though the Master attacked them with Autons, Frobisher was able to free the captured companions, and they helped the Doctors fight off the Autons, as Adam had a change of heart when the Master revealed he intended to use the chronal energies he had stolen across the Doctor's timelines to destroy the universe. After the Master killed Adam as he foiled his plans, the eleven Doctors honoured Adam as a "true companion". (COMIC: Endgame)

Detours with Martha
Following a Calamity Lamp, the TARDIS landed on the planet Loam inside the head of a High Goliax, which was being controlled by a child called Kipe. Martha was separated from the Doctor when Kipe ejected her from the head, while the Doctor was captured by Kipe's father, Kingfish, who was the manager of the Krib bank. The Doctor was taken through a space portal to the Krib, and Kingfish explained to the Doctor that the planet was being cleared by the High Goliax as part of a clearance as collateral for a loan.

The Doctor realised that the processors in the bank were living slaves pining for home and that they had started singing that morning because of the TARDIS automatically translated alien languages. The Doctor told Mandrake to attach the bank's free-reins to their "tentacles", while the Doctor changed control from the Krib's accumulator to the speculator to allow them to move freely. After being reunited with Martha, the Doctor saw Loam's former Prime Minister, Sugarpea, sacrifice her life to end Loam's debt to the Krib.

The Doctor and Martha ran through a portal to a High Goliax head while followed by the freed slaves, which the Doctor explained were the minds of the High Goliax finding their way home after being ripped from their skulls centuries before. The Doctor told Mandrake to help evacuate the children from the High Goliax as the minds found their way to their original bodies, stopping the attack. (COMIC: The Woman Who Sold the World)

The Doctor went looking for a Karadax octopus Droid in the caves of Karadax, and was aided by an android duplicate of Martha, which originated from a museum dedicated to the Doctor. (PROSE: Rewriting History)

In 1930 New York City, the Doctor and Martha investigated kidnappings from Hooverville, a community of people hit by the Great Depression with nowhere left to go, befriending their leader, Solomon. They also met Tallulah, in search of her boyfriend Laszlo, who had disappeared a few days prior. Investigating the sewers, the Doctor discovered Pig slaves that worked for the Cult of Skaro, who were kidnapping humans with high intelligence for their Final Experiment; the pig slaves were created from those of low intellect. The group ran into Laszlo, and saw how the Daleks had partially transformed him into a pig slave, but he managed to escape with his mind still his own. The Doctor discovered that the Daleks were trying to evolve into new forms in order to survive, and the Cult of Skaro's leader, Dalek Sec, transformed himself into the first human-Dalek hybrid as part of this plan. (TV: Daleks in Manhattan)

To the Doctor's surprise, Sec grew compassionate due to his new humanity, wishing to no longer conquer Earth, instead wanting the Doctor to take the new human-Dalek race to a new world in his TARDIS. However, Dalek Caan and the other members of the Cult betrayed Sec, stripped him of his authority, exterminated Solomon and continued with their mission to conquer Earth, filling the captive humans with pure Dalek DNA. The Doctor climbed to the top of the Empire State Building and got in the way of the solar flare that powered the experiment, adding Time Lord DNA to the hybrids.

After Sec was killed by Dalek Thay in the defence of the Doctor, the Daleks fought the hybrids. Jast and Thay were killed in the battle and Caan deactivated the hybrids as failures, leaving himself the sole surviving Dalek. The Doctor attempted to negotiate with Caan, but the Dalek performed an emergency temporal shift and fled. Laszlo began to die due to the pig slaves' limited lifespan, but the Doctor, using the laboratory built by the Cult, cured his deterioration. However, he couldn't fix Laszlo's disfigurement, so he left him and Tallulah to live their lives in peace as new residents of Hooverville, where no one would judge Laszlo's appearance. (TV: Evolution of the Daleks)

The Doctor took Martha to Harankast, where they stopped ruthless car-dealer Joseph Manver from brainwashing the population into buying cars that polluted the planet, destroying the countryside. After closing his car business, the Doctor had Manver arrested by the local authorities. (COMIC: Exhausting Evil)

The Doctor brought Martha back home, exactly twelve hours after they left, planning to leave and continue his travels alone. However, he decided to stay after hearing that Professor Richard Lazarus was going to "change what it meant to be human". Attending Lazarus' demonstration, the Doctor met Martha's family, with her mother, Francine, taking an immediate dislike to him. The Doctor discovered Lazarus had created a machine to restore youth, similar to the regeneration process. However, the machine backfired, mutating Lazarus into a monster that fed off the life force of others. Following Lazarus into Southwark Cathedral, the Doctor saved Martha and her sister, Tish, from being drained by Lazarus by using his sonic screwdriver to enhance a pipe-organ to reverse the machine's effect and revert Lazarus to his original self, but not before Lazarus had fallen to his death. Per Martha's request, the Doctor took her on as his official travelling companion. (TV: The Lazarus Experiment)

Official travels with Martha
After losing the TARDIS in the time winds, the Doctor and Martha took up residency on a luxury astroliner called Tritanic. However, the ship was attacked by the Skrawn, whose homeworld had been destroyed in the Last Great Time War. The Skrawn stole the astroliner's experimental time-nav system to overpower the Kolox nebula. In pursuit, the Doctor found his TARDIS aboard the Skrawn's ship, and stole the time-nav, leaving the Skrawn lost in the Kolox nebula. (COMIC: The Skrawn Inheritance)

After a bad experience with the dinosaurs, Martha asked to return to the Royal Hope Hospital, where the Doctor found a faction of Cybermen that had not been not sucked into the Void, having been made on Earth during the Battle of Canary Wharf. The Doctor was then arrested by Captain Shelia Shandron, who wanted his help against the Cybermen. The Doctor phoned Martha and found she had been kidnapped by the Cybermen. Their location found, the Doctor and Sandron prepared for the Cybermen's attack. After the attack, the Doctor arrived at the Cybermen's base, the Millennium Dome, and pretended to help release the Cybermen trapped in the void, when he actually created a time portal to bring a dinosaur to defeat the Cybermen. (PROSE: Made of Steel)

The Doctor encountered the Zygons in 1909, (PROSE: Sting of the Zygons) and was nearly forced to be a living exhibit in the Gallifreyian section in the Museum of the Last Ones. (PROSE: The Last Dodo)

After upgrading Martha's phone in mid-travel, the Doctor locked onto the distress call sent out by the SS Pentallian, that was plummeting into the Torajii sun. The Doctor offered to help evacuate the ship, but was unable to when the TARDIS was trapped in the ship's boiler room. A malevolent force that had possessed the husband of the ship's captain, Kathryn McDonnell, began reducing the rest of the crew to cinders. Eventually, the Doctor discovered that Torajii was sentient and seeking revenge on McDonnell for scooping out some of it to use as fuel, and possessed him. Holding off possession long enough, the Doctor told Martha how to get rid of the fuel to appease Torajii. She did so with the last surviving crewmembers and the Doctor was released from its possession. (TV: 42)

The Doctor next took Martha to Maught, a planet resembling the American Wild West, where he stopped three criminals, Tu, Blontt and Angelo, from stealing water of gold. (COMIC: The Green, the Bad and the Ugly)

The Doctor and Martha searched for the Infinite, a spaceship also sought by Baltazar. (TV: The Infinite Quest)

While in Blackwood Falls, the Doctor encountered the Hervoken, old enemies of the Carrionites, and prevented them from using the energy of the townspeople to launch their ship. (PROSE: Forever Autumn)

The Doctor next found a Voracious Craw heading towards Tiermann's World. He and Martha arrived there to save the Tiermann family, but due to the intelligence at the heart of the Dreamhome, the Domini, being possessive of the family, they could only save Solin. They then chased the Voracious Craw off Tiermann's World by using a copy of the alien's species to scare it off the planet before it could finish consuming it. (PROSE: Sick Building)

The Doctor and Martha visited Fraxinos, where they met Natalie Sharrocks, who was on the run from the Chelonian. Investigating, the Doctor was led to a company called the Body Bank, which allowed the aged to regain youth via mind transference. Undercover as a health inspector, he learnt an entity had taken Natalie's body whilst she was at the clinic to destroy a Chelonian breeding planet. The entity took control of another patient, who later died of a heart attack, killing the entity and saving Natalie from Chelonian retribution. (PROSE: The Body Bank)

The Doctor and Martha visited the Great Solar Shield, which was used to partially block sunlight from 21st century Earth to ease the effect of global warming. A race called the Silhouettes began leeching energy from the Shield and its crew. The colour in Martha's shirt scared off the Silhouettes, who instead began heading for Earth. The Doctor realigned the Shield's prismatic mirrors to refract a rainbow towards the Silhouettes, scaring them off. This caused the Sihouettes to flee, and the Great Solar Shield's crew were returned to Earth in the TARDIS. (COMIC: Sunscreen)

Being human
The Doctor and Martha found themselves being pursued by the Family of Blood, who wanted a Time Lord body to achieve a form of immortality as they had a limited lifespan. (TV: Human Nature) Rather than confront them directly, the Doctor, out of mercy, chose to hide from them instead. (TV: The Family of Blood) He used a Chameleon Arch to transform himself into a human school teacher named John Smith in 1913 England, completely repressing his Time Lord biology, and sending Martha undercover as his maid to protect the Arch, as his alter ego would have no recollection of the Doctor, only dreams of his adventures.

However, John Smith fell in love with the matron of the school, Joan Redfern, (TV: Human Nature) and initially refused to change back as he had adapted to a normal life and had foreseen a bright future with Joan, but decided to allow the Doctor to retake his Time Lord body so he could stop the Family from killing anyone else.

Haunted by all the death and destruction his act of mercy had caused, the Doctor gave the Family their immortality, with ironic punishments: he trapped Father of Mine in chains forged in a dwarf star, imprisoned Mother of Mine in the event horizon of a collapsing galaxy, suspended Son of Mine in time as a scarecrow and trapped Daughter of Mine in every mirror in existence. He asked Joan to travel with him, telling her that he was capable of all the things John Smith had been, but she refused, knowing that John and the Doctor were no longer the same person. (TV: The Family of Blood)

Battles in time
During a trip to a supermarket, the Doctor and Martha encountered a rampaging warrior called Thaur, one of three warrior kings exiled from Norsum by a goddess called Angboda. During a scuffle, Martha caught Thaur's crystal necklace, his only link with his homeworld. Looking into the crystal, the Doctor saw a fleet of war-craft under construction, commanded by Angboda in order to attack civilisations across the galaxy. Instead of handing him over to the authorities, the Doctor took Thaur aboard the TARDIS to stop the attack on the galaxy. (COMIC: Wrath of the Warrior)

The Doctor and Martha located Thaur's fellow warrior king, Vulsturg the Vast, imprisoned on a planetoid. When they tried to free him, flying creatures emitted a deafening scream. Reversing the sonic field of three hearing aids, the Doctor blocked the sound and rescued Vulsturg. When a large beast tried to stop their escape, the Doctor attached the three hearing aids to each of its three ears then set them back to a normal setting. The beast was overcome by the amplified screaming and fell unconscious. The Doctor, Martha, Thaur and Vulsturg then left in the TARDIS to find the third warrior king. (COMIC: The Screaming Prison)

After the Doctor recovered from being incapacitated by the green mists of Orion's Belt, (COMIC: Ground Control) he and Martha travelled to a prison on Haklok, only to find the place littered with bodies, including those of robo-sassins, which had been sent to stop the group from finding the warrior kings. Looking into Thour's crystal, the Doctor realised that Angboda's fleet were in fact hospital ships travelling to help the worlds that Thour and his two fellow warriors had attacked. Having been tricked by Thour, the Doctor and Martha were left behind as the three warriors stole the battle cruiser and set off to avenge themselves against Angboda. (COMIC: Force and Fury)

Angry at being tricked, the Doctor travelled to Queen Angboda's hospital ship to defend it against Thour's imminent attack. With no weapons to use, the Doctor, Martha and Angboda instead jettisoned everything in the ship's cargo bay, creating a reflective barrier with Thour's laser that heavily damaged his ship and caused it to crash onto a barren asteroid, leaving the three warrior kings stranded and powerless once again. (COMIC: Warriors' Revenge)

The Doctor became incapacitated by the green mists of Orion's Belt, forcing Martha to drive the TARDIS. (COMIC: Ground Control)

Responding to a distress call from Professor Dinsdale of the Interplanetary Archaeological Institute on Brendock Seven, the Doctor discovered Dinsdale's team had been killed trying to open an ancient burial mound. The Doctor managed to bypass the door's sonic disruptor, and found the Vortex Cannon, a weapon created by an ancient civilisation that was capable of universal catastrophe. To his horror, the Doctor unmasked Dinsdale as a shape-changing Zaan Warrior, and the Zaan escaped with the Cannon, only to be destroyed by the guardians of the burial mound. The Zaan commander survived and escaped in an escape pod. Knowing that Treed Crystals that powered the Cannons were found only on the planet Garvrath, the Doctor and Martha set off in pursuit of the Zaan commander. (COMIC: Head Start)

After spending a while tracking the Zaan, the Doctor and Martha attended a film premiere, knowing that the leading star, Honey Vox, would wear a Treed Crystal, and would be a likely target of the Zaan. They contacted her and discovered the Treed Crystal locked in her safe, but stolen by Jebelex the Pulthasian using a matter transmuter. As the Zaan arrived, Jebelex tricked them into thinking he had chucked the crystal to Martha and escaped in his ship. Using the matter transmuter, the Doctor and Martha went off in pursuit of the crystal, following a trail of Jebelex' DNA. (COMIC: Jewel of the Vile)

Tracking Jebelex to Karaten, the Doctor was thrown into a living water entity by the hostile villagers, where he found the skeleton of Jebelex, and the Treed Crystal. On the Doctor's instructions, Martha used Jebelex's matter transmuter to turn the liquid solid, freeing the Doctor and allowing him to destroy the entity. With the crystal in his possessions, the Zaan arrived and kidnapped Martha, threatening to kill her unless the Doctor delivered the crystal to their homeworld. (COMIC: Lock, Stocks and Barrel)

After chasing the Zaan across space, the Doctor discovered the crystal was actually a trap. He freed Martha and tricked the Zaan into using the crystal, trapping the Zaan and their homeworld in a time-loop for eternity, although he did feel a sense of guilt for what he had done. (COMIC: End Game)

Further travels with Martha
The Doctor stopped a swamp monster from attacking a colony on the planet Sunday by tricking it into possessing him and, using a new protein-RNA mix, destroyed the creature. (PROSE: Wetworld)

The Doctor and Martha visited 1915 Antarctica, where Ernest Shackleton's Imperial Trans-Antarctic Expedition on the Endurance had crashed, near where Skith scientists had been experimenting with inserting Skith DNA into a whale. When the Skith discovered they were not the first to discover Earth, they deemed their expedition a failure, and began to use their spaceship, Oppressor One, to freeze the Earth and convert any remaining lifeforms below into Skithself. With Shackleton's help, the Doctor destroyed the ship by sending it into the sun. (COMIC: The First)

On a trip to 2375 Egypt, the Doctor and Martha watched the Great Pyramid of Cheops vanish. Intrigued, the Doctor found that other Seven Wonders of the Ancient World were vanishing from across the globe. Arriving at the Hanging Gardens of Babylon, the Doctor and Martha were approached by a Talithan swindler called Pholonius Ginn, who planned to sell the wonders on g-Bay. All three were then teleported to the deep space station headquarters of the FatKat Corporation, an auction for planet Earth and all inhabitants born in the Humanian period. Ginn bought Earth, but the Doctor disrupted the deal as Ginn had bought control of every inhabitant of Earth except Martha, which subsequently ruined his business deal. Afterwards, the Doctor returned the Seven Wonders to their original positions. (COMIC: Minus Seven Wonders)

The Doctor and Martha next became caught up in a decade-long alien war and discovered the guns used in the war placed the target in suspended animation rather than killed them. The Doctor stopped one of the last survivors, Elphon, from slaughtering everyone involved in the war in a desperate act to end the raging conflict. He brought the two warring species together and freed the hundreds of warriors that had been suspended. (COMIC: The Last Soldier)

After watching the Beatles in 1960s Liverpool, Martha was kidnapped, and the Doctor traced her to Gelezen, a planet that was isolated from the rest of the universe thousands of years prior. Breaking the time field around Gelezen, the Doctor stopped the Gelezens from taking Martha's human DNA to survive, instead giving them his own genes to ensure they had a long future. (COMIC: Signs of Life)

The Doctor asked Martha to wait at a coffee shop while he searched a town centre to trace the source of an etheric beam. When the signal disappeared, he returned to Martha, believing it "must have been a blip." (PROSE: Needle Point)

Wanting to solve the mystery of Stonehenge, the Doctor parked the TARDIS at the same spot a few moments at the same time each year and had the TARDIS scanner take snapshots to document the construction of Stonehenge. (PROSE: The Secret of the Stones)

The Doctor discovered a Vurosis in Creighton Mere and, to prevent it from harming the populace, killed the alien by forcing its mutategenic powers back on it, (PROSE: Wishing Well) encountered space pirates in the 40th century, (PROSE: The Pirate Loop) and found living weapons known as the Clade causing trouble in 1880. (PROSE: Peacemaker)

While on an adventure in 2008 to stop "four things and a lizard" during a "migration", the Doctor met Sally Sparrow, who gave him a folder of information, telling him that it would be vital to him in the future when he would get stuck in 1969. (TV: Blink)

After arriving on a planetoid that should not have existed, the Doctor and Martha found that the world around them was being formed from Martha's memories of her childhood books by a Ch'otterai that wished to use the power generated from imagination to create a new universe to rule over. When the Ch'otterai tried to threaten him into taking it to the Land of Fiction, the Doctor tricked it into entering the TARDIS, where it was destroyed by the TARDIS's powerful imagination. (PROSE: The Mystery of the Haunted Cottage)

Trapped in 1969
The Doctor and Martha were transported back in time to 1969 by the Weeping Angels while investigating strange disappearances at Wester Drumlins in 2007. Using the information given to him by Sally, the Doctor left messages for her to find in the future and bring the TARDIS to 1969 to collect him and Martha. Given that he did not use his name in these messages, (TV: Blink) those other than Sally who learned of the messages, like Justin Richards, took to calling him "the Easter Egg man". (PROSE: The Secret Lives of Monsters) The Doctor created a device, the Timey-wimey detector, to track people displaced in time by the Angels. (TV: Blink)

Whilst in 1969, he and Martha were pursued by a Weeping Angel again and attacked by Autons. They worked with the Thirteenth Doctor and her friends to pit the two enemies against each other, resulting in the Nestene Consciousness being sent back in time. The two Doctors incorrectly believed they had avoided creating a paradox and parted ways, with the Tenth Doctor and Martha remaining in 1969 to await the TARDIS. (COMIC: A Little Help from my Friends)

The Doctor and Martha tracked down Billy Shipton when he arrived in 1969, having been touched by the same Angel as them. From Sally's notes the Doctor was able to give him a message to pass onto Sally in 2007 to help her investigation and that he would die shortly after meeting her again. Sally succeeded in sending the TARDIS back in time to him. (TV: Blink)

Final travels with Martha
While wandering the jungle on a planet he assumed had no intelligent life, the Doctor discovered a face carved into a tree that told him that the environment collapsed, causing one-hundred years of acid rain, dissolving the planet's people and their civilisation, somehow making them into a collective mind that was part of the planet for millions of years. Because they had run out of stories, the world intended to make the Doctor and Martha join them as they had new stories to tell. The Doctor rushed Martha back to the TARDIS before the falling acid rain could hit them. (PROSE: The Planet That Wept)

With the TARDIS materialisation field damaged, the Doctor and Martha became trapped on the Seamancer on 2008 Earth for a few days whilst the TARDIS recalibrated, where they met Captain Ketley and his crew. Before they could leave, they and the crew were transported to the ocean world of Surobos, where they were sentenced to death by the Suroban. Making a deal with a friendly Suroban, the Doctor ventured into the ocean to retrieve his TARDIS and returned the Seamancer crew to Earth. (COMIC: Shipwreck!)

Seeking some quiet time, the Doctor took Martha to an icy alien city called Isqaron, where they discovered the city was melting and that the population believed it was the work of a god called Asharoth. Empress Tamil believed the Doctor to be an escaped slave of Asharoth and had him thrown through a dimension gateway. The Doctor found himself deposited on Earth, where he learnt a group of scientists, led by Professor Milligan, were using Isqaron as air conditioning for Earth, pumping hot polluted air to Isqar and sucking cold air back. The Doctor convinced scientist Kate Curran of the dangers they were doing and destroyed Malligan's work with her help. He and Kate then flew through the gateway in a helicopter and saved Martha and the city. (COMIC: Cold War)

On Lumana, the Doctor and Martha were enlisted into protecting the Loomish from the reptilian Slaken. However, he soon discovered the Loomish were con artists and had led him off to find the Slaken so that they could take up residency in the TARDIS. Martha tricked the Loomish into thinking one of their family members were in danger, and she and the Doctor quickly escaped in the TARDIS when the Loomish left the ship. (COMIC: House Pests)

The Doctor and Martha landed at Research Base Truro, where they found the dead bodies of aliens after something "terrible" had happened. (COMIC: Death to the Doctor!)

After detecting an inexplicable power source, the Doctor and Martha travelled to Zetheda, only to discover the whole planet to be overflow with un-recycled waste. They were attacked by the Worgoth, but were saved by the Ratlings, who had sent the distress signal leading the TARDIS to Zethenda. The distress beacon also attracted the attention of the Optimi, a race of evolving humans who wanted to colonise the "paradise" world of Zethenda and destroy the Ratlings. Escaping, the Doctor, Martha and the Ratlings activated a terraforming device hidden underground that created a paradise landscape. (COMIC: Waste Not)

At Christmas in the 38th century, the Doctor took Martha shopping in Oxford Street, where he encountered Jimmy and "Bert". Spending Christmas with them, the Doctor learnt Jimmy had fallen under the control of another Klytode, who wanted to use Jimmy's new ecopower station to unleash the Prime Klytode onto Earth. He succeeded and Klytodes began invading London. Refusing to allow Bert to sacrifice himself, the Doctor reversed the hyperspatial link that brought the Klytode to Earth, sending the Prime Klytode and his army back to where they originated. (COMIC: A Klytode Christmas)

An energy stream from a distress beacon forced the TARDIS down to a planet, where a girl called Cora had been attacked in the woods by a beast. After returning Cora to the village, Martha discovered the villagers had similar bite marks on them and were anaemic. The bio-mechanical beast, Viktor, tried taking both the Doctor and Martha to the Thane's castle, but Gideon freed the Doctor. The Doctor and Gideon came to the castle where they found a neuropathic generator was pacifying the Khamirae villagers. Martha tried and failed to warn the Doctor against destroying the generator. When he did this, Gideon and the rest of the villagers began transforming into bestial forms.

When the Doctor knocked out Gideon, he realised that the Thane and Viktor were using DNA samples from the villagers to extend the Thane's lifespan so they could continue watching over them after repeated cloning of the Thane degraded his pattern. The Doctor, aided by Viktor, repaired the generator by routing power through the Thane's distress beacon, but Viktor died protecting the Doctor from the attacking Khamirae. The Doctor suggested to the Thane to lower the output of the generator every so often so the Khamirae could control their transformations. The Thane refused to clone himself any further and decided to spend the remainder of his life letting the Khamirae come to terms with who they truly were. (COMIC: Universal Monsters)

The return of the Master
On another refuelling trip to Cardiff, the Doctor caught a glimpse of Jack Harkness running towards the TARDIS. Due to his Time Lord nature having an inbuilt rejection towards Jack's "impossible existence", the Doctor set off immediately after the TARDIS was refuelled, but Jack managed to jump onto to the exterior of the TARDIS. The TARDIS, reacting badly, made an uncontrollable leap into the Time Vortex, with Jack clinging on to it, until it made it all the way to Malcassairo at the end of the universe. After Jack revived from the fatal trip, the Doctor had a tense reunion with him.

Whilst investigating the planet, the Doctor, Martha and Jack saved a human from being hunted by cannibalistic humanoids called the Futurekind. Fleeing the Futurekind, they entered the Silo 16, the asylum of the last survivors of the universe and the launching point for the most ambitious trip in history: Utopia, supposedly a haven beyond the collapse of reality. The Doctor, Jack and Martha assisted Professor Yana and his assistant, Chantho, in powering up the rocket. However, the Doctor learnt Yana was actually, having made himself human to escape the Last Great Time War using a Chameleon Arch, and also learned that his name was an anagram of the Face of Boe's secret (You Are Not Alone).

Restoring his Time Lord consciousness out of curiosity from Martha's questions about his watch, Yana became the Master again, and killed Chantho, but not before she was able to shoot him. Facing imminent regeneration, the Master locked himself inside the Doctor's TARDIS and, once he regenerated into, hijacked the ship and escaped, leaving the Doctor, Jack and Martha to be killed by the Futurekind at the end of the universe. (TV: Utopia) The Doctor was able to fix Jack's vortex manipulator, and used it to escape the Futurekind and travel back to 2008.

Once there, the trio discovered the Master, using the alias "Harold Saxon", had been elected Great Britain's Prime Minister. He framed them for terrorism and planted explosives in Martha's flat, forcing the Doctor, Martha and Jack to go on the run. He also made sure they remained powerless by sending Jack's team at Torchwood Three to the Himalayas and captured Martha's family, after he had tricked Martha's mother into helping him entrap the Doctor.

On board the Master's airship, the Valiant, the Doctor discovered his TARDIS had been turned into a paradox machine. After failing to use a perception filter to foil the Master's plot, the Master summoned the Toclafane, whom he ordered to assassinate US President Arthur Winters, attack the Earth, and decimate the population. He then killed Jack and aged the Doctor into a frail old man with his laser screwdriver as he tried to reason with him. (TV: The Sound of Drums) As the Toclafane began slaughtering the population, the Doctor sent Martha away with Jack's vortex manipulator after whispering his plan to stop the Master into her ear. (TV: The Sound of Drums, Last of the Time Lords)

Being kept prisoner aboard the Valiant for a year, the Doctor, Jack and the Jones family witnessed the Master and the Toclafane devastate Earth's civilisations and reduce the human race to camps of survivors, and suffered at his hands themselves, while the Doctor realised that the Toclafane were the humans he had encountered at the end of the universe, and began to telepathically hack into the Archangel Network.

After Martha returned to the UK, the Doctor was further aged into a diminutive body by the Master as a warning to Martha. When Martha allowed herself to be taken to the Master for execution, she and the Doctor revealed their plan; using the Archangel Network, the Doctor harnessed the psychic energy of humanity's hope, as Martha had spent a year travelling the world telling humanity about his importance to them, regaining his youthful appearance in the process. He then forgave the Master for everything he had done, inflicting a blow to the Master's ego. On the Doctor's orders, Jack destroyed the paradox machine keeping the Toclafane in the present, undoing the entire year; Earth was restored as time resumed for everyone else right after the President was killed, but those on the Valiant retained their memories of the year due to being at the "eye of the storm".

Urging the Jones' against descending to his level for revenge, the Doctor planned to imprison the Master in the TARDIS, but Lucy Saxon, the Master's human wife, shot him, and the Master refused to regenerate in an act of defiance against the Doctor, and died in his arms. After burning his body, the Doctor offered Jack the chance to rejoin him on the TARDIS, but Jack declined, saying that he was still needed at Torchwood Three. (TV: Last of the Time Lords) Repairing the TARDIS, but forgetting to put his shields back up, (TV: Time Crash) the Doctor prepared to depart with Martha, but found she also wished to leave him to help her family recover from the year-long ordeal they had suffered, and also told him she was in love with him, but knew he'd never return her feelings. However, she gave him her upgraded mobile phone so that she could call him if trouble arose. (TV: Last of the Time Lords)

Shields down
Immediately after Martha left, the Doctor crashed his TARDIS into that of his fifth incarnation's, which put the universe in danger of being sucked into a Belgium-sized black hole. However, the Tenth Doctor used his memory of the event from his fifth incarnation's viewpoint to create a supernova at exactly the same moment the black hole appeared. After giving a heart-felt speech of appreciation to the Fifth Doctor, the Doctors' TARDISes separated and the two parted ways. (TV: Time Crash) Before he could turn the TARDIS' shields back on, the spaceship Titanic crashed through the walls. (TV: Last of the Time Lords, Time Crash, Voyage of the Damned)

After fixing the damage to his TARDIS, the Doctor attended a party on the Titanic on Christmas Eve, 2008, where he befriended Morvin and Foon Van Hoff and a waitress named Astrid Peth. During a brief trip to Earth with Astrid, the Van Hoffs, Mr. Copper, and a Zocci named Bannakaffalatta, the Doctor also met Wilfred Mott, who informed him that London had evacuated in fear of another alien attack on Christmas day.

When the ship's owner, Max Capricorn, had a meteor shower purposely crash into the Titanic so that it would crash on Earth and wipe out six billion humans to bankrupt his treacherous company, the Doctor took command of his surviving friends, and an arrogant businessman named Rickston Slade, and tried to lead them to safety. However, Morvin died, and Foon and Bannakaffalatta gave their lives to save the others. Whilst his party of three survivors reached the flight deck, the Doctor was taken prisoner by Capricorn and was nearly killed by the Heavenly Host. He was saved by Astrid, who lifted Capricorn with a forklift, taking him with her into the Titanic's nuclear storm drive. With Capricorn deceased, the Hosts recognised the Doctor as the new authority and took him to the steering wheel, where he, alongside Midshipman Alonso Frame, stopped the Titanic from crashing into Buckingham Palace.

Using Astrid's teleport bracelet, the Doctor managed to bring Astrid back, but only as a partially cohesive form. Devastated, he kissed her goodbye and allowed her atoms to scatter into space to see the universe. The Doctor then went to Earth with Mr. Copper to find his TARDIS. The Doctor rejected Copper's request to travel with him, though, as Copper had accidentally brought more than enough credits to live comfortably on Earth, he left to start a new life for himself, while the Doctor set out on his own, (TV: Voyage of the Damned) stopping at UNIT to recommend Martha for a job as a way of thanking her for everything she had done for him. (TV: Reset, The Sontaran Stratagem)

Caught in a paradox
Whilst travelling alone, the Doctor became embroiled in the paradoxical timeline that a paradox triggered by his encounter with the Thirteenth Doctor in 1969 had created, where the Sea Devils now ruled Earth. He discovered an alternate version of Rose Tyler in 2020, who was a resistance fighter opposing the Sea Devils, and persuaded her to come with him to correct the timeline. As he took the TARDIS back to the point of divergence, 1903, it collided with the Thirteenth Doctor's TARDIS which was making the same journey. The two Doctors stabilised their TARDISes and the Doctor and Rose boarded the future Doctor's TARDIS. The Tenth Doctor and Rose accompanied Team TARDIS and rogue Skithra Queen as they discovered that the Skithra had successfully captured Nikola Tesla and Thomas Edison and were attempting to awaken Sea Devils at the Raven Peninsula. After stopping them, the team infiltrated the Skithra ship to rescue the scientists, with the Tenth Doctor insisting he rescue them so he could meet them. He, Rose and the Thirteenth Doctor’s companions rescued them and returned to the TARDIS, where the Thirteenth Doctor revealed she and the Queen had successfully sabotaged the ship and dematerialised before it exploded. During the journey, the Tenth Doctor distracted Edison from the TARDIS by asking him basic questions about electricity. After the scientists were returned to Earth, the Tenth Doctor left with Rose in his own TARDIS.

Before his memory of the paradox faded, the Doctor took Rose to the restored 2020 however she realised there was nothing for her there, as it was not her timeline, and asked to be dropped her off on a planet in need of liberating. (COMIC: Alternating Current) The Doctor lost his memory of the paradox and found himself in another paradoxical timeline where the Dalek Restoration Empire was active without knowledge of the Time War, (COMIC: Defender of the Daleks) unaware this timeline had been caused by temporal fluctuations created by his own future self interfering in the Dark Times. (PROSE: The Guide to the Dark Times) He was captured by the Daleks and brought before the Emperor on Skaro, annoyed that the Emperor of all the people had been restored by the paradox. The Emperor told him the Daleks were at war with the Hond, who the Doctor believed should have died out in the Dark Times, and requested his help. Reluctantly he agreed, believing the Hond could be a greater threat than the Daleks, and was sent to meet the Prime Strategist. He and the Strategist investigated the Vault of Obscenities and encountered a Hond, discovering a way to pacify them by ending their constant pain. The Doctor had the Daleks deploy this method as the Hond approached Skaro's defences and was successful, however a Grey Dalek turned on him and ordered his extermination. The Doctor was rescued by the Thirteenth Doctor who took him back to his TARDIS. Escaping Skaro, the two Doctors parted ways for good. (COMIC: Defender of the Daleks)

Solo adventures
Detecting an unstable space-time manipulator which disturbed the very existence of the universe, the Doctor used the TARDIS to pursue it in a race through time and space against the Daleks, Judoon or Slitheen, each of whom wished to acquire it. Ultimately, however, after chasing it through from the Time Vortex to New Earth, the lunar surface, and the London Blitz, the Doctor finally caught the space-time manipulator back in the Time Vortex before destroying it. (GAME: Doctor In A Dash)

Within the TARDIS, an accident caused the Doctor's consciousness to be transferred into the TARDIS' memory core, forcing him to travel through the TARDIS' neutral network to escape. (GAME: Eye of the TARDIS)

When an ancient alien parasite inhabited his mind, the Doctor lost his memory and took up residency in a boarding house owned by the Manns family in 1940. Working with Robert Mann, the Doctor discovered the parasite had inhabited the oak tree in the village and sucked it into the time vortex, regaining his memory and control over his mind. Afterwards, the Doctor had dinner with the Manns and the local villagers. (PROSE: Number 1, Gallows Gates Road)

Visiting a house on Christmas Eve 1920, the Doctor met a boy named Tom Wake. He discovered a sonic screwdriver hanging from the tree and a note for him with the screwdriver, which thanked him for saving the family's life on Christmases in the next nine decades. With this, the Doctor travelled to every Christmas between 1920 and 2007, protecting the Wake family. As time passed, the Doctor grew closer to Tom, his wife and their children and grandchildren. Eventually, the Doctor and Tom reached Christmas 2007 and discovered it was Tom who left the note for the Doctor, instructing him to protect his descendants. (PROSE: The Hopes and Fears of All the Years)

The Doctor went on the trail of the Extron, a galactic criminal, after the alien parasite kidnapped Violet Hopley, a nine-year-old girl. He located the Extron on the desolated planet Onla-toch in the 957-Dogron system, which the Extron devastated many years prior. After re-capturing the Extron, the Doctor returned Violet to her parents on Earth. (COMIC: The Monster Upstairs)

Intending to brush up on his language skills, the Doctor's lesson was cut short when he became trapped in the News Factory, a virtual world of crystalline matrix populated by journalists, including married couple Ray and Boudica Royce, whom the Doctor allied with to destroy the aggressive SubEds and the News Factory itself by distrupting the crystalline matrix. (COMIC: Hot Metal)

Landing in a cavern next to a pool of superheated water, the Doctor came under attack from flying aliens called Shrikes. He was rescued by a youngster called Kaze, who led him to a village and the villager's leader, Genji, who invited him to the Ceremony of Choosing, when warriors to defend the village against the Shrike were selected. After the ceremony, the Doctor and the rejected group were thrown from a cliff and came across a crashed spaceship which had used up all its energy shielding itself from the Shrikes. The Doctor landed his TARDIS on the ship, connected his engines with the ship and gave it enough power to launch. (COMIC: The Halls of Sacrifice)

After burning toast in the TARDIS, the Doctor was forced to land in a purple alien jungle, where he met Mason Burns, an archaeologist searching for the final resting place of the Old Kings of Skarab. The Doctor joined him on his quest and, after battling giant scorpions and escaping various traps, he discovered a group of humans had been turned into gorillas by the kings centuries prior. Finding and sealing the kings' tomb, the Doctor left Mason to lead a revolution on Skarab. (COMIC: The Old Kings of Skarab)

The Doctor was summoned to 19th century China by an old acquaintance, Chan Chiu, and learnt that immortal spirits were operating at the temple of Qingyange. Taking Chan's nephew, Li, to investigate, the Doctor found the spirits under the command of a stone monkey and his governor. Taken prisoner, the Doctor challenged the stone monkey for the future of Earth: they both had to defeat a dragon to seal their power over Earth. The Doctor won the challenge, defeated the dragon and drove the stone monkey and his spirits away from Earth. Leaving, the Doctor travelled to the future and visited Li in his eighties, as he was telling his grandchildren about their adventure. (COMIC: Reign of the Stone Monkey)

The Doctor stumbled onto Majenta Pryce's operation in the Hotel Historia, a chain of time-travelling hotels that had been destroyed in the Last Great Time War, while confronting the Graxnix in 41st century London and used the faulty tech to travel back to the hotel. The Graxnix followed the Doctor and started to kill people at the hotel. Majenta quickly decided to leave with her bills unpaid, but the Doctor prevented her escape. He used her time travel technology to imprison the Graxnix outside time, and then ensured she was taken to debtors' jail. (COMIC: Hotel Historia)

The Doctor took part in a polar expedition on Grothender, (COMIC: Wormhole) and bumped into Winston Churchill while searching for Sontaran grenades in 1895.

After finding the corpse of Dr. Kaleb Loss on the poisonous planetoid Death's Door, the Doctor returned Loss to the Institute of Exo-Contamination Treatment base on Mustron V, only to be attacked by the base's protector, a Vox. He was saved by Rachel Barlow and allied with her to unmask a sabotuer who was distrupting the team's work. After an attempt was made on their lives, the Doctor and Rachel discovered a medical officer, Jennifer Arden, was responsible due to her disagreement with the methods of the team's leader, Mick Hogan. When Jennifer infected herself whilst fighting with Hogan, the Doctor used samples collected by Kaleb Loss to cure her. (COMIC: The Poison Planet)

The Doctor found a giant creature called Zzazik was responsible for a storm in 1816 Switzerland, and trapped it in sparks of electricity.

Visiting the Vienna State Opera, the Doctor found the great tenor, Anton Mordillo, was actually a member of the Thieves' Guild of Kardol, a group of alien con-artists wanted in seven star systems, but allowed him to continue his opera career. (COMIC: The Great Mordillo)

Early exploits with Donna
While investigating Adipose Industries, the Doctor was reunited with Donna Noble. With her help, he used two Adipose Industries pendants to prevent a million Londoners from being killed and their organs and skeletons converted into Adipose babies. The Doctor tried to save the life of Matron Cofelia, the foster mother to the few thousand Adipose, but the Adiposian First Family's ship dropped her as it took aboard the incomplete harvest of Adipose, killing her due to her being a liability to their crimes Deciding to take Donna on as a companion, the Doctor and Donna were both quick to rule out the possibility of a romantic involvement, making their companionship dynamically different from those of Rose and Martha. He flew the TARDIS to where her grandfather, Wilfred Mott, was looking at the stars through his telescope, waving to him along with Donna before heading off into the stars. (TV: Partners in Crime)

While Donna was lost in the TARDIS, the Doctor decided to turn over the mattress of the bed William Shakespeare had given him to prevent the psychic hole in the bed from seeping through the memory hay. Wanting to test the bed, the Doctor found Donna and pushed her onto bed to see if there were any side effects. After nothing happened, the Doctor told Donna the history of the bed. (PROSE: Appendix - The Last Will)

For her first trip in time, the Doctor accidentally took Donna to 79 Pompeii, where they discovered Mount Vesuvius was on the verge of its historical eruption. Initially determined to escape to avoid tampering with the fixed point in time, the TARDIS was sold to the marble merchant Lobus Caecilius before the Doctor could return to it. Despite trying to leave when he reunited with it, the Doctor took an interest in the stone circuits the augur Lucius Petrus Dextrus had designed for Caecilius to make. The Doctor discovered Pyroviles were attempting to take over the Earth after losing their own world by converting humans into their own kind by using the circuits as an energy converter. Having the choice between the death of the entire world or of the thousands in Pompeii, the Doctor made Vesuvius erupt, with Donna's help and support. Per Donna's request, the Doctor saved Caecilius and his family, becoming their household gods. (TV: The Fires of Pompeii)

Setting the TARDIS controls on random, the Doctor ended up taking Donna to the Ood Sphere in 4126. Upon finding a dying Ood, the Doctor was shocked to see it display red eyes; worried that he may run into an old foe, the Doctor decided to investigate. He and Donna sneaked into Ood Operations, where they discovered the Ood of the Second Great and Bountiful Human Empire were slaves. They soon discovered that Oods were born with secondary brains, which gave them individuality; however, they were lobotomised and had the translator put in its place. Allied with Ood Sigma, they turned off the force field preventing the Ood from connecting to the Ood Brain, while the CEO of the Ood Operations was turned into Ood as punishment. (TV: Planet of the Ood)

At Donna's request, the Doctor took her to Hollywood in 2012, where they discovered Amelia Hubble, a creature capable of sucking thoughts and ideas out of the brain, had brought the town to a standstill. After falling under Amelia's control himself, the Doctor stopped her from destroying the last talent in the city, Alan Crawford, and allowed her to draw creative plasma energy from the internet, saving the celebrities she already claimed and restoring Hollywood. The Doctor and Donna returned to Hollywood a year later to find that Amelia and Alan had got married. (COMIC: Nightmare on the Boulevard)

The Doctor and Donna next travelled to Calcutta, where they were forced to stop Darac-7 from turning humans into Gelem warriors, (PROSE: Ghosts of India) and to Planet 1, where the Doctor was hunted for sport by Sebastiene, (PROSE: The Doctor Trap) Soon after, the Doctor and Donna visited a dairy farm in 1970 and defeated turbine-shaped plant creatures. (COMIC: Windswept)

The Doctor and Donna stopped the anti-robot Cult of Shining Darkness from carrying out their plans, but at the cost of the cultists being caught in an explosion. (PROSE: Shining Darkness)

The TARDIS picked up a number of distress signals coming from Death's Deal, the most lethal planet in the universe, and the Doctor and Donna went to answer them. On the planet, the Doctor found a video message from his next incarnation, asking him to locate Professor Erskine on the planet, obtain his research and use it to reveal to the galactic authorities the existence of slaughter crystals on the planet. The Doctor found Erskine, but the scientist had gone crazy due to the loneliness, and tried to kill him by sacrificing him to a gigantic coral creature. The arrival of the TARDIS saved his life, and the Doctor managed also to save the life of Lyric, Erskine's daughter, but he was unable to save her father. The Doctor then sent Erskine's research to the galactic authorities, and, having understood that the electrical waves of the distress signals made the planet dangerous, he shut them down, bringing the planet back to normal. (AUDIO: Death's Deal)

Helping Martha
Whilst teaching Donna how to pilot the TARDIS, the Doctor received a call from Martha, who led him back to UNIT in 2009 to investigate the ATMOS-related deaths across the Earth. Alongside Private Ross Jenkins, the Doctor discovered the Sontarans were working with teenage genius Luke Rattigan to create ATMOS; they also replaced Martha with a clone, to keep them updated on the movements of the Doctor and UNIT. (TV: The Sontaran Stratagem) The Caesofine gas was emitted from ATMOS-equipped cars across the Earth to be used to breed more Sontarans for the war against the Rutans. After finding and freeing the real Martha, the Doctor used an atmospheric converter, built by the students at Rattigan's school for gifted children, to ignite the atmosphere, destroying the gas. The Sontarans' next plan was to simply conquer Earth. Rattigan, having been betrayed by the Sontarans, sacrificed his life to destroy the flagship with the converter, swapping places with the Doctor at the last minute.

While bidding Martha a farewell, the TARDIS' doors unexpectedly closed, and the TARDIS began dematerialising on its own power, (TV: The Poison Sky) transporting the Doctor, Donna and Martha to the planet Messaline in the year 6012. There, DNA was stolen from the Doctor and replicated to produce Jenny, his biological "daughter". Initially critical of the girl due to her predilection for violence and being a reminder of his lost family, the Doctor came to feel for his daughter after much persuasion and help from Donna.

After the Doctor activated the Source, a terraforming device that had become a subject of mythology, Messaline became inhabitable and the war between humans and Hath on the planet ended. However, before the Doctor could take Jenny aboard the TARDIS, she was shot by General Cobb, who had aimed for the Doctor before Jenny had stepped in his way, and died in her father's arms. Heartbroken, the Doctor was tempted to execute the detained general, but overcame the urge, and used his resistance in order to help found a new society on the planet. (TV: The Doctor's Daughter)

Having a fun time
The Doctor and Donna watched the courtship of the Zyglots, ran from intelligent dogs in a flying house, joined forces with a survey team to escape a living swamp, witnessed "something" bring time to a halt, saw the Beatles perform "My Bonnie" at The Cavern Club, chased after "vampire goth cannibals", saw time get meddled with while being chased by Cossacks, and got infected by a reality-altering psychic parasite. (COMIC: The Time of My Life)

The Doctor next took Donna to a leisure planet called Splendorosa, where they visited a floating city called Coral. Intrigued by the city, the Doctor went undercover at GeoCorp, the company responsible for the city's position in the sky. He came into conflict with the company's CEO, Volsairius Trefgar, after he and Donna uncovered a plot to "steal" Splendorosa by Trefgar and the war-like Sarriflex, who intended to transport the planet to a galaxy at war in order to use it as a weapon. The Doctor stopped them by disrupting their ships, bringing Coral City back to the land in the process. However, he and Donna, instead of being honoured for saving the population from a deadly war, were chased out of the city by a lynch mob, as the population had grown fond of "living in the sky". (PROSE: Grand Theft Planet!)

Answering a distress signal in the Arctic Circle, the Doctor and Donna met Professor Renfrew and joined him and his team in their search for the corpses of ten miners. When Renfrew was killed, the Doctor discovered an Ice Warrior called Issaxyr was searching for a frozen Ice Warrior army. He discovered the Ice Warriors had planned to unleash a Spanish flu pandemic during World War I to weaken Earth. However, they were all killed by the Spanish flu themselves. With his army dead, the Doctor returned Issaxyr to Mars to help rebuild the Ice Warrior civilisation. (PROSE: Cold)

The Doctor and Donna visited China during the Qin dynasty, where they were thrown into a crater for being foreigners and faced a robotic soldier made of ceramics. Donna defeated it by disrupting the control signal with her mobile phone. The two were taken to the Imperial Palace of the first Emperor, Qin Shi Huang, who had become a cyborg. Donna was threatened by the Emperor's general, Meng Tian, who was really an alien gangster, and Meng remotely awakened the soldiers of the Terracotta Army and shut down Qin Shi Huang. Donna made a call on her mobile phone, stopping the signal that paralysed Qin Shi Huang, waking him up again. While Qin Shi Huang and Meng were fighting each other, Meng shot at the warp converter, which shut down the Emperor and the Army, while also burying the whole palace in an explosion. The Doctor and Donna escaped the exploding palace. (COMIC: The Immortal Emperor)

The Doctor was reading a collection of short stories when he realised that the words of one of them, Variations by David Banderson, changed each time it was read. The Doctor and Donna broke into Banderson's house when there was no answer at the door, and they discovered he was being influenced to write stories by a creature in the computer screen that was kept alive by stories. Donna was nearly caught in the creature's trap too, but the Doctor intervened. He pulled Banderson away from the computer and began typing at a speed that drew the entire creature into his words. The Doctor then printed the first pages of the story, with the creature trapped in its pages, and deleted all the text from the computer file. Banderson was freed from the creature's influence, and as a result, every time Variations was read, the reader was reading their own version of events. (PROSE: Once Upon a Time)

After the TARDIS became damaged, the Doctor and Donna were taken prisoner by a space-junk dealer called Silas Wrench, who wanted to sell the TARDIS as scrap and sell the Doctor and Donna to slave masters. Alongside a Horobot, the Doctor used the TARDIS mesion recognition defence system to knock Silas unconscious. He and Donna regained the TARDIS, and the Horobot crashed Silas' ship into the desert to prevent his escape. (COMIC: Any Old Iron, Merchant of Menace)

The Doctor and Donna were captured by the Family of Blood after Daughter of Mine had escaped the mirrors by possessing Nancy Latimer and freed Father and Son of Mine. The Family intended to commandeer the TARDIS to free Mother of Mine, but the Doctor was able to escape his restraints and, after the TARDIS rendered the Family unconscious, freed Nancy from her possession. The Doctor then imprisoned the entire Family in the event horizon of the black hole, and returned Nancy to her grandfather Timothy. (PROSE: Blood Will Out)

The Doctor and Donna were present in London during the coronation of Elizabeth II on 2 June 1953, where they fought a large winged humanoid that was subdued by Eva De Ville. (COMIC: Where's the Doctor?)

Deep in the Ardennes, the Doctor rescued Charlemagne from an insane computer. (TV: The Unicorn and the Wasp, PROSE: The Lonely Computer)

Working with Agatha Christie, the Doctor became embedded with a murder mystery at Eddison Manor in 1926. The Doctor discovered Arnold Golightly, a Vespiform/human hybrid, was the murderer; he was mentally connected to Agatha by the Firestone, causing him to imitate her literature. Donna threw the gem into the lake, drowning Golightly, who went after it; the link damaged Agatha's short-term memory. The Doctor dropped her off at the Harrogate Hotel. (TV: The Unicorn and the Wasp)

Whilst dealing with a small dinosaur situation, the Doctor found the time to give William Shakespeare a hand writing The Tempest. (PROSE: The Tempest - A Work in Progress)

At a performance by the thief Fergus Antelect, the Doctor used the telepathic abilities of Antelect's Ood, Ood Delta, to manipulate the minds of the audience into thinking he had confessed to the crimes. Delta told Special Agent Ratner that though it was true that Antelect had not committed theft through manipulating chronometers, he was guilty of thirty-seven counts of theft, ninety-two counts of misleading the public through illegal telepathic manipulation, and one hundred and thirteen counts of cruelty to a sentient life form due to his abuse towards Delta. Delta projected memories of what actually happened at every one of Antelect's performances into the minds of the people in the room. The Doctor advised Ratner to check the security videos for the shows Antelect performed at, and Antelect was arrested. (PROSE: Disappearing Act)

Arriving on the International Space Station in 2058, the Doctor formed an alliance with researcher Truman Truss to battle space insects called the Mange Mites. (COMIC: Attack of the Mange Mites!)

Enemies in time
Visiting the 22nd century, the Doctor investigated the deaths of a gang of criminals after seeing their car explode with them inside, interrogating Laura Efston. (COMIC: Pawns of the Zenith) He discovered the population of London was being possessed by the Zenith, (COMIC: Swarm of the Zenith) which had hacked into Earth's satellites and had begun rewriting the DNA of humans. He targeted Donna, who, in her possessed mind, attacked the Doctor. (COMIC: Prey of the Zenith)

Resisting the Zenith, the Doctor was transported to the Zenith's lair, and fled back to London to set up a firewall to stop their conquest. The Zenith ordered him to stop interfering, threatening to kill Donna if he didn't. However, the Doctor activated the firewall nonetheless. With the Zenith signal cut, Donna and the rest of London were freed. (COMIC: Lair of the Zenith)

Officially meeting River Song
The Doctor received a message on his psychic paper instructing him to go to the Library in the 51st century, where he met Professor River Song, a "very important" woman from his future, who had called him to help a team of archaeologists representing the Felman Lux Corporation to investigate the planet, which had been sealed off a century prior with the message "4022 saved. No survivors." The group discovered the Library was infested with Vashta Nerada. When the swarm began hunting Dave, the Doctor used his sonic screwdriver to increase his spacesuit's integrity, discovering that River had her own sonic screwdriver supposedly from his future self when she did the same to the others. He decided to teleport Donna back to the safety of the TARDIS with the Library's teleporters, (TV: Silence in the Library) with the sudden appearance of a time fly distracting the both of them before she could object. (COMIC: A Stitch in Time) However, Donna failed to make it, being "saved" into the Library's Data Core instead. (TV: Silence in the Library) After the time fly was devoured by the Vashta Nerada, (COMIC: A Stitch in Time) the Doctor returned to the group but they were forced to flee when the swarm occupied Dave's suit and began marching on them, discovering a Node with Donna's face on to his horror. As the group continued through the library, the Doctor managed to convince the Vashta Nerada to communicate, learning that the library was their forest. He continued to distrust River until she revealed that she knew his true name, which deeply shocked him. The Doctor realised that the four thousand and twenty-two people being "saved" literally meant they had been teleported and saved into the data core, however the core began going into meltdown. Strackman Lux took them to core, revealing the computer was the preserved mind of a little girl who had been dying.

Realising the computer needed more memory, the Doctor devised a plan to connect his mind to it and intimidated the swarm into giving him a single day to save the people in the core. Knowing he would not survive the process, River knocked the Doctor out and handcuffed him to a railing, sacrificing herself to boost the Library's memory, enabling it to return the people who had been saved in the core, including Donna. The Doctor reunited with Donna as the people departed as per his deal with the Vashta Nerada, (TV: Forest of the Dead) unbeknownst to him he was observed by one of Clara Oswald's echoes. (TV: The Name of the Doctor) As they prepared to depart, the Doctor pondered why his future self had given River a sonic screwdriver and discovered it had actually saved River by preserving her data ghost. He uploaded her into the core's virtual reality, having fixed the core so it could reunite her with the uploaded data ghosts of her deceased team. As he returned to the TARDIS, the Doctor tested snapping his fingers to open its doors, something which River had told him his future self could do, and was delighted when it worked. (TV: Forest of the Dead)

After having lost her husband, Lee, in the virtual world created in the Library, Donna decided to take a break from travelling with the Doctor and he returned her home to Chiswick. (AUDIO: Out of this World)

Last exploits with Donna
Whilst Donna returned home and became reacquainted with her friend Natalie Morrison, the Doctor was kidnapped by the Collectors. He contacted Donna to rescue him and they resumed their travels (AUDIO: The Chiswick Cuckoos).

The Doctor and Donna visited the London Technology Museum and the Doctor became interested in the M-pad which had a built-in A.I named Silvi. When people started becoming scared of their technology, he and Donna investigated however his mind became affected, rendering him unable to use the sonic screwdriver and TARDIS, though not before he‘d traced the source of the effect to to the Underground. There he and Donna found the Koggnossenti base and got themselves purposely captured to distract the aliens so Kevin could ram it with a train to force their machinery to turn off. Whilst the humans escaped in the confusion, the Doctor tampered with the Koggnossenti's machine so it would affect them. He gave them a chance to leave however the Koggnossenti reactivated the machine regardless and hurriedly attempted to retreat upon realising they were being affected, only to perish when they inadvertently blew up their ship. (AUDIO: Technophobia)

The Doctor and Donna travelled to Calibris to procure a new fluid link for the TARDIS from Soren. They discovered the Time Reaver weapon was loose on the streets and the Vacintians had occupied Calibris in search of it. They discovered the gangster Gully had acquired the weapon from Cora, the daughter of the Vacintian commander. Upon finding the Time Reaver with the Vacintians, the Doctor defused it by exposing all of its energies to him, slowing time around himself so much it felt like decades had passed in mere minutes. Once he resumed normal time, Donna informed him that Gully had escaped and they departed whilst the Vacintians withdrew. (AUDIO: Time Reaver)

The Doctor and Donna visited Shadow Cay on 2009 Earth, which was really a disguised Sycorax spaceship occupied by a group widowed by the 2006 Sycorax invasion which hypnotised humanity into believing the "island" had been discovered by Columbus. After being separated from Donna, the Doctor discovered the Sycorax had been animating zombies. The Doctor broke the control of the zombies, but the Sycorax had a curse put on the phage abstracts that boarded a nearby plane. The phage abstracts intended to release a virus on humanity that would leave humanity in immense agony and prevent them from dying in revenge for the loss of the Sycorax widows' husbands once it landed in London.

Though unable to stop the phage abstracts himself, the Doctor controlled the abstracts outside the Church of the Sycorax to make the Sycorax ship overload by recreating the whole of Earth with the ship's magma-sculptor. Donna, having stowed away on board the plane with Norah, flew the plane back towards Shadow Cay, and the Doctor caught Donna duplicating hands from a "drowning giant" sculpture with the magma-sculptor. Jean saved the Doctor from being killed by the Haxan Craw, and the Doctor stopped Jean from dying along with the Haxan Craw. The Doctor, Donna, Jean and Norah escaped the ship after the Doctor set its controls to take off before it exploded. (COMIC: The Widow's Curse)

The Doctor prevented the Mandragora Helix from spreading influence through the internet, and then sent it out into space, confused and with memories missing. (PROSE: Beautiful Chaos)

On a visit to the Myolthen galaxy, the Doctor and Donna lost the TARDIS when it was swept away by a waterfall. Caught up in a raging waterfall themselves, the Doctor and Donna were saved by Jeb, a fisherman from Zentos 3. He, along with a group of intelligent bears, helped the Doctor to locate the TARDIS. (COMIC: Washed Away!)

Taking Donna to the ancient Acropolis of Xentha in Galaxy 12, the Doctor encountered the Titanoleum Army and foiled their plot to convert holidaymakers into Teglatrons. (COMIC: Titanoleum Tourists)

During a visit to Donna's family on Earth, the Doctor and Donna watched a program called Hunting Makeover, led by Donna's old acquaintance, Justin. Noticing that weird phenomena did indeed happen around him, the Doctor suspected that he was the cause. He and Donna's family pretended to be a family and participated at the program, pretending they wanted to restore a haunted house in Chiswick where Justin used to live as a caretaker. During the program, they found the remains of two aliens who had been buried alive there, and the Doctor figured out that it was their last desperate telepathic message to haunt Justin. Through a series of accidents and trials prepared for him, the Doctor and the Nobles led Justin to accumulate enough psychic energy to make him capable to expel the message from his brain, thus freeing him from the curse. (AUDIO: No Place)

At Donna's request, the Doctor took her to Vallarasee for a holiday, in spite of his personal distaste for how the place had changed since his last visit. As they were following a guided tour in one of the many attractions of the place, a door closed, trapping Donna and other tourists inside a room filling with water. The Doctor saved them by smashing the door, only to be immediately arrested by the Judoon for "vandalism" and put into custody. While waiting for judgement, he was informed by Thispus that the dome protecting the city from the water was failing. In order to save everyone, he tricked a Judoon recruit, Clo, so that he would bring him to the leaders of the city. After many attempts, he finally managed to save the town by having Clo arrest all the tourists for various charges, an action which prompted the Judoon to raise the city over the sea to arrest everyone. (AUDIO: One Mile Down)

Arriving during the Great Smog of London, the Doctor and Donna stumbled across the Fumifugium's attempt to invade Earth using the smog as a cover. They managed to repel the invasion with the help of Ivy Clark, Richard Cooper and Terry Hopkins, before leaving with them for the sea to have a proper holiday. (AUDIO: The Creeping Death)

The Doctor and Donna visited the leisure planet Midnight, where Donna stayed at the Leisure Palace, whilst the Doctor took a four-hour ride on the Crusader 50 bus to the Sapphire Waterfall. However, the bus was attacked by an unknown entity, which possessed one of the passengers, Sky Silvestry, causing her to speak at the same time as others around her or repeating them. The creature eventually appeared to have passed into the Doctor, causing him to become catatonic, as Sky was, while repeating Sky's words. She incited mass hysteria among the other passengers, though it was she who the creature was still possessing. Before the creature could trick the passengers into throwing out the Doctor, Sky was dragged out into the X-tonic sunlight by the bus' hostess. (TV: Midnight)

After a turbulent ride in the vortex, the Doctor crashed the TARDIS at a science convention, where he and Donna witnessed Professor Eustace Krosson invent a wave-time vector detector that unleashed the Imago, parasites from the fourth dimension that devoured people's personal timelines. The Doctor tricked their queen into devouring Donna, a time traveller, which sent the Imago back to their own dimension and released everyone they had devoured, including Donna. (COMIC: Time Flies)

Visiting a garden centre at Christmas, the Doctor and Donna ran into a Snowdemon creature, and they helped the Pixees to put it on trial for its crimes. (COMIC: Frosty the Snowdemon)

While celebrating Christmas Eve inside the TARDIS, the Doctor and Donna went out to fetch a Christmas tree, and Donna was kidnapped by living snowmen and robotic Santas. The Doctor rescued Donna, and accidently ran into the real Santa Claus during their escape to the TARDIS. On Christmas morning, the Doctor received a new sonic screwdriver from Santa, while Donna received a fresh hot chocolate. (PROSE: Dr. Tenth: Christmas Surprise!)

When they travelled to the French Rivera in the 1780s, they met Rudolph of Goritania and Donna became his Queen and ran away with him. The Doctor tracked her down to Goritania and warned her about Death who was approaching the castle. He eventually conceded he'd been hostile to Rudolph due to not wanting Donna to leave and gave his blessing, unaware Donna had just discovered the marriage was a trap. He interrupted the ceremony to try to stop Donna being surrendered to Death but she rejected his help and danced with Death, who could not destroy her anyway because her underwear was made from the royal standard. Donna chose to continue travelling with the Doctor. (AUDIO: Death and the Queen)

Reunions and farewells
The Doctor and Donna visited the planet Shan Shen, where the Time Beetle, a member of the Trickster's Brigade, created an alternate universe around Donna while she had her fortune told; a universe where the Doctor died fighting the Empress of the Racnoss and Donna teamed up with Rose Tyler to go back in time and get the Beetle off of her back. After Donna corrected the timeline by killing herself in the alternative universe, she was able to give the Doctor a message from Rose, "Bad Wolf". (TV: Turn Left)

Realising that the barriers between universes were breaking down, the Doctor rushed back to 2009 Earth, where he initially found everything was normal, but the planet vanished when he and Donna returned to the TARDIS. Finding no clue as to its location, the Doctor went to the Shadow Proclamation and learned twenty-seven planets had also been stolen, such as Adipose 3, Pyrovillia, and the lost moon of Poosh. Realising from Donna that bees had been disappearing from Earth, the Doctor connected the Migrant Bees of the Tandocca Scale to the Medusa Cascade, and concluded that the planets were there.

Fleeing the Shadow Proclamation, the Doctor and Donna arrived at the Medusa Cascade, only to find it apparently empty, until a phone call to the TARDIS from Jack, Martha and Sarah Jane allowed him to track down the Earth, which he discovered had been stolen by Davros and his new Dalek Empire; Davros had been saved from the Time War by Dalek Caan, at the cost of Caan's own sanity.

After landing on a ravaged Earth, the Doctor finally reunited with Rose, but he was mortally wounded by a passing Dalek before he could properly embrace Rose. After Jack destroyed the Dalek, the Doctor was taken into the TARDIS, where the Dalek's gunshot forced him to regenerate (TV: The Stolen Earth) to heal himself. Once his body was restored, the Doctor was able to channel the excess regenerative energy that would have changed his appearance into his nearby severed hand as a bio-matching receptacle, leaving him healed while remaining in his current incarnation. (TV: Journey's End) However, the act did use the eleventh of the Doctor's twelve regenerations, leaving him with only one remaining, an action his successor stated was due to "vanity issues". (TV: The Time of the Doctor)

The TARDIS was taken aboard the Dalek ship Crucible, where the Doctor, Rose and Jack were captured, but Donna was locked inside the TARDIS and the Doctor assumed her and the TARDIS lost when it was sent to the Crucible's Z-Neutrino core. As the Doctor's secret army gathered on the Crucible, Davros forced the Doctor to remember everyone who had died in his name and how he had turned all of his companions into weapons and willing murderers, which unveiled the Doctor's "soul".

However, before Davros' reality bomb could be detonated, a new Doctor, born from the severed hand when Donna touched it, arrived in the TARDIS, having piloted it away from being destroyed at the last second, to assassinate Davros, only for Davros to thwart the attempt, electrocuting Donna in the process. However, the meta-crisis made Donna part-Time Lord, with Davros' electrical attack transforming her into the "DoctorDonna". Donna then disabled the planet powered reality bomb to stop Davros from destroying reality itself and the Doctors and their companions overpowered the Daleks and sent the planets back to their original time and place. Whilst the Doctor worked on returning Earth home, the meta-crisis committed genocide against the Daleks, horrifying the Doctor. As the Doctor's companions retreated to the TARDIS, the Doctor offered to save Davros and Caan. Davros refused, hatefully denouncing the Doctor as "the destroyer of worlds", while Caan predicted that one of the Doctor's companions would still perish. The Doctor and company used the TARDIS to tow Earth back to its original location as the Crucible exploded.

The Doctor said his goodbyes to Sarah Jane, Martha, Jack and Mickey before he left the meta-crisis Doctor in the Pete's World with the Rose and Jackie, hoping Rose would help him control his dangerous ways just as she had done to him in his previous incarnation. Upon returning to his own universe, the Doctor was dealt another emotional blow as he was forced to remove all of Donna's memories of travelling with him, as her human mind was deteriorating due to her Time Lord part killing her. He returned Donna to her family, and told them they would have to make sure she never remembered him. After receiving comfort from Wilfred, the Doctor left to travel on his own. (TV: Journey's End) Whilst grieving in the TARDIS, the Doctor discovered Donna had recorded a message on Emergency Program One to say goodbye to him, knowing that one day she would be forced to leave him. (COMIC: The Time of My Life)

Still in mourning, the Doctor's mind was taken over by Es'Cartrss of the Tactire, who had been stuck on the Dalek Crucible and was unable to return home before his planet was returned, but the Doctor's link with the TARDIS forced them both into the Matrix, where the Doctor lost his memories. He was surprised to come across a room dedicated to nine of his previous incarnations. Assisted by a TARDIS impersonation of Martha, the Doctor began recalling past adventures, eventually gaining control of his memories. The Doctor and his TARDIS, which was now impersonating most of the Doctor's past companions, fought Autons, Eight Legs and Clockwork Droids, and the Doctor seemingly killed Es'Cartrss. Having regained his memories, the Doctor decided to take an overdue trip to the planet Barcelona. (COMIC: The Forgotten)

Settling down with Rose-the-cat and K9
Falling into a depression, the Doctor spent some time sulking in The TARDIS; apparently making so few travels that vast spider-webs began to grow in the control room. He soon began to binge-watch emotional films, such as Love Actually, The Lion King, and Annie Hall, as he ate large quantities of ice cream. Still heartbroken over the loss of Rose Tyler, he adopted a cat which he gave her name to. Owning a cat was initially far from what the Doctor expected it to be. Directly after bringing her into the TARDIS, Rose scratched the Doctor up and ran off. The Doctor would not see her for five days. When he did see her again, he lectured her for being "a bit rubbish," but Rose mainly ignored him during the conversation.

While sulking in bed and crying over the loss of Rose Tyler, Rose-the-cat brought the Doctor various animal carcasses she had collected as gifts in a bid to cheer him up, but only succeeded in making him sadder over the death of all of the various creatures.

After finding out Rose-the-cat had pulled down all of the suits in his closet and sat on them, leaving them covered in neon hair, the Doctor planned to travel to Deva Loka to relax, but discovered that Rose had scratched up his long brown coat, ruining it. Enraged, the Doctor left Rose dangling outside in a space-suit as he considered how he was nowhere near as merciful as he used to be.

Rose warmed up to the Doctor's presence and after a while the two began to get along fine. Rose at one point asked the Doctor if he had ever had any other pets in the TARDIS, and the Doctor unveiled a personal version of K9 that he had kept on the ship. Standard for most dogs and cats, Rose and K9 did not get along. Their first encounter ended with Rose attacking K9 with the sonic screwdriver and K9 entering "defence mode." The Doctor once again resulted to leaving the two dangling outside the ship as punishment.

While walking together, Rose-the-cat suggested that the best option for getting over Rose Tyler was for the Doctor to get a "rebound companion". The Doctor was initially reluctant, but eventually agreed. However, on the night of his "blind date", he was apparently stood up and opted to return to the TARDIS, where his potential companion, a member of the Sisters of Plenitude, was petting Rose. Upon seeing this, the Doctor angrily reminded Rose that they were there to find a new companion for him. Afterwards, the Sister asked if she needed to leave.

Rose at some point was infected with fleas, and, while the Doctor was initially playful in teasing Rose's newfound friendships, he eventually realised that it was becoming a serious health hazard for the feline. Refusing to use regular flea cures, the Doctor took Rose to a planet made entirely of candy floss surrounded by a gas that was irresistible to insects. The Doctor placed Rose in the stuff and successfully cured her of her pestilence, but doing this also shaved most of the hair off of her lower body. In a "genius" solution, the Doctor put Rose in a miniature blue suit much like his own. While the Doctor and K9 were amused by the situation, Rose was not.

Frustrated by how caught up he was over his now-ended relationship, Rose would spend a majority of her time on the ship trying to help the Doctor move on. The Doctor, meanwhile, found himself content in accepting his two pets as his new companions, and all that he needed. Rose and the Doctor eventually parted ways, with the Doctor deciding that it was about time to finally find a new companion. (COMIC: A Rose by Any Other Name)

Lonely exploits
The Doctor found, floating in a bottle in space, a message from River Song on psychic paper, inviting him to join her at the Apocalypse Vault. Knowing that the opening of the Vault was a fixed point in time, the Doctor refused to go and instead tried to track down River. What followed was a chase from planet to planet, where River always left a message for him and he liberated a few species on his way. Eventually he tracked her down to the location of the Apocalypse Vault a few centuries early, discovering a forged copy of the Scroll of the Last Days she’d left. He gave up pursuing her whilst she wrote to him demanding the scroll back, as he visited an avian species and had adventures with Jane Austen. He finally agreed to meet her at a cafe where she manipulated the Fifth Doctor into taking the scroll. Afterwards, the Doctor uncovered numerous times River had contacted his earlier selves to go to the Apocalypse Vault and was terribly angry, believing her to be a thief who had tricked him. However, after she helped him escape an undersea base he’d set to autodestruct, he met with her again and finally agreed to go to the Crypt. He arrived early and opened all the doors so she could choose what to do with the original Scroll, as a test of who she really was. Upon returning to the TARDIS, he found a recording from River, which revealed she’d borrowed the ship to replace the original Scroll with her fake at the initial closure of the Vault, altering history to prevent the anticipated atrocity the original Scroll would cause without threatening the fixed point. She revealed his involvement was her plan to help him get over the loss of Donna. (AUDIO: Expiry Dating)

The Doctor arrived on Arcopolis to destroy the Fortress, which contained a weapon that was left behind after the Last Great Time War. An alien force called the Eyeless attempted to steal the weapon themselves, but the Doctor successfully destroyed the weapon and defeated the Eyeless. (PROSE: The Eyeless)

The Doctor arrived at BASE and discovered a series of bizarre murders had taken place at the sports training facility. His investigation was interrupted by the arrival of Sontarans led by Major Stenx, who were hunting a Rutan. The Doctor helped the students survive the deadly games the Sontarans devised as an experiment, working with Emma. With the Sontarans defeated, the Doctor confronted Emma and revealed he'd deduced she was the original murderer and was actually a Rutan. They were attacked by the wounded Stenx, who shot Emma just as she killed him. Solemn at the deadly outcome, the Doctor departed. (PROSE: The Sontaran Games)

Alone in the TARDIS, the Doctor attempted to compose his own piece of music, but was interrupted when a Graske teleported in. Inquiring as to what the harmonious sound echoing through the TARDIS was, the Doctor explained that it was the Music of the Spheres. Alerted by the Graske to a hole in space which manifested at the entrance of the TARDIS, the Doctor found that it had appeared within the Royal Albert Hall in London. Calling his piece "Ode to the Universe", the Doctor passed his sheets through the hole for the orchestra to perform as he assumed the role of conductor using the sonic screwdriver. Finding that the Graske had travelled through the hole to London, the Doctor realised that he had lied to him in order to reach Earth, and so he prevented him from creating any more trouble by reversing the polarity of the neutron flow. Returning the Graske to the TARDIS, the Doctor used the sonic screwdriver to send him to the end of the galaxy. (TV: Music of the Spheres)

Unknowingly making an "illegal park", the Doctor found that the TARDIS had been locked by the Judoon, forcing him to crack a set of security codes so could penetrate the force field holding the TARDIS and escape. (GAME: Jobsworth Judoon)

To his confusion, the TARDIS took the Doctor to the middle of space. Unknown to him, Jenny had just travelled through that region. (AUDIO: Zero Space)

Saving the Krikoosh
Seeking to take his mind off things, the Doctor went to 22nd century Earth to visit a zoo. Spotting a Krikoosh, a rare specimen with the ability to pass through solid matter by destabilising molecules, the Doctor witnessed its theft at the hands of surviving Daleks while he was left at the mercy of animals whom the Daleks had induced into a frenzy to provide a distraction. (COMIC: Carnage Zoo) Making his escape on a Vulgle, the Doctor pursued the Daleks to their hideout, where he rescued the Krikoosh, (COMIC: Flight and Fury) which used its ability to save the Doctor from Dalek firepower.

After making their presence known, the Daleks deployed their specially created proton cannon against humanity. Rendering everyone intangible just as the Doctor and the Krikoosh were, it was the Daleks intent to take over Earth unhindered as humanity would be left to waste away. (COMIC: The Living Ghosts) However, unbeknownst to the Daleks, the Doctor had made a partnership with the Krikoosh and, with its power, was able to enter the Dalek's base and modify their cannon to turn against them while restoring humans to their solid state. Judging their failure an unacceptable outcome, the Daleks self-destructed. (COMIC: Extermination of the Daleks)

Quest for the Eternity Crystal
After arriving on the Moon in the 30th century, the Doctor discovered a powerful device called the Eternity Crystal, created by the Karagulan society called the Darksmith Collective, for an undisclosed client. The Collective lost it. When they discovered it was located on the Moon, they sent an agent to collect it, but the Doctor had taken it to prevent them from having it. (PROSE: The Dust of Ages)

Whilst he was trying to understand the history of the Eternity Crystal, the Doctor travelled to the graveyard planet, Mordane, where its power had been tested by the Collective. However, the Crystal began to reanimate the dead bodies, but the Doctor managed to defeat them, and made them inanimate again. The Agent eventually arrived and took back the Crystal on behalf of the Collective. (PROSE: The Graves of Mordane)

In pursuit of the Agent and the Crystal, the Doctor arrived on Karagula, the homeworld of the Darksmith Collective. When the Doctor accessed the Darksmith's underground base via the Dark Cathedral, he retrieved the Crystal. In an attempt to understand the Crystal's purpose, he wanted to track down the person who initially constructed the Crystal, Brother Varlos, former member of the Darksmith Collective. (PROSE: The Colour of Darkness)

After tracing Varlos, the Doctor arrived in an underwater base on Flydon Maxima. However, the Collective dispatched a military force called the Dreadbringers to retrieve the Crystal, and the Doctor battled the native lifeform of Flydon, the Blaska. He discovered that Varlos had already departed from Flydon, and left behind his daughter called Gisella. Gisella told him that Varlos was the person who buried the Eternity Crystal on the Moon, because he realised that the Crystal was uncontrollable, and left it behind until he could find a way to destroy it. She told the Doctor that Varlos had travelled back in time, and settled in 1895 Paris. (PROSE: The Depths of Despair)

Arriving in Paris, the Doctor and Gisella found Varlos living under the alias Baron De Guerre, who was killed by a Time Vampire that was pursuing Varlos through the Time Vortex. The Doctor began investigating the deaths caused by the vampire, with the assistance of Inspector DuPont, who helped them discover that the vampire was an artificial alien, created by the crew of a spaceship to collect energy to refuel it. However, when it had amassed enough energy, it returned to the ship to discover the crew had already died. Reverting to its sole purpose of gathering even more energy, and without the means to discharge the energy, the creature became unstable. To defeat the vampire, Varlos gave his own life when he drained the vampire's time-energy using his own body, a mock Eternity Crystal and Gisella. (PROSE: The Vampire of Paris)

The Doctor began tracking the Agent across the Milky Way, and followed him to the Silver Devastation. The Doctor arrived in Devastation Hall during the Game of Death, an event devised by the Nocturn to lure humans. He found out that the Agent was destroyed by the Nocturn, Zalenby. The Doctor and Gisella departed and avoided being killed by the Nocturnes in the Game of Death. (PROSE: The Game of Death)

To find out who employed the Darksmith Collective to construct the Eternity Crystal, the Doctor arrived on Ursulonamex, where the Collective met with their clients. Expecting the planet to be lush and beautiful, upon arrival they found it had been scorched and charred to remove all trace of their arrival. The Doctor learnt from the survivors that evidence of their identity might exist in an observation station in orbit around Ursulonamex. On board the station, the Doctor found a Dravidian Hive, but the Doctor and Gisella escaped from them, and were unable to uncover any evidence about the Collective's mysterious clients. (PROSE: The Planet of Oblivion)

While in flight, the TARDIS was captured by the Shadow Proclamation, and the Doctor was put on trial. Because Gisella was Varlos' daughter, the Crystal was legally returned to her, as it was officially Varlos' property. However, Gisella betrayed the Doctor, when she handed over the Eternity Crystal to the Collective. Although, she accidentally revealed the Darksmith's secret rendezvous point, the location where they were meeting their infamous clients. (PROSE: The Pictures of Emptiness)

The Doctor arrived in the designated location, London in 2009. Whilst he was there, he discovered the clients were really the Krashok. He also found out that Gisella was an android all along, who was created by Varlos, and who had been reprogrammed by the Darksmith Collective to give them the Eternity Crystal when she collected it. When Gisella and the High Minister of the Collective, Drakon, handed over the Crystal to the Krashok, Drakon was killed as soon as he fulfilled the deal, which broke the Collective's conditioning over her. (PROSE: The Art of War)

The Doctor discovered that the Krashok planned to use the Crystal to target their fallen warriors and to resurrect them, making them an invincible fighting force. They intended to detonate the Eternity Crystal unless the Doctor stopped them. To give him an incentive to do so, they trapped Gisella on their ship, aware that he wouldn't let her die, despite being an android that had been hoodwinked by the Collective. However, the Doctor eventually rescued Gisella, defeated the Krashoks and the Darksmith Collective, and destroyed the Eternity Crystal in the process. After the Doctor had completed his mission with the Eternity Crystal, he left Gisella behind to live out a normal life as an android. (PROSE: The End of Time)

Afterwards, Gabby begged the Doctor to take her to see the universe, with the Doctor agreeing to take her on one trip after she told him "no song should end too soon". (COMIC: Revolutions of Terror)

For her first journey in the TARDIS, the Doctor took Gabby to the No-Gallery of Ouloumos, where they discovered that a block transfer artist, Zhe Ikiyuyu, was missing from the gallery, having been exiled to her private moon. While investigating in her retreat, Zhe's apprentice, in conflicting male and female forms, menaced the Doctor and Gabby before Zhe awakened from her stasis and pulled them into her, revealing they had been conflicting aspects of her personal psyche. Impressed by Gabby's skills in the crisis, the Doctor decided to allow her to be a full-time companion. (COMIC: The Arts in Space)

Returning to Brooklyn so Gabby could see her family, the Doctor discovered a mysterious increase in noise pollution throughout the city. He used the sonic screwdriver to deduce the noise increase was a cry for help from the Echoes, beings of living sound that were being hunted by Shreekers, who were enslaving them to harvest their energy for weaponry. Escaping back to the TARDIS on a moped, the Doctor and Gabby travelled to the Empire State Building, where the Doctor began tuning the mass to absorb the sonic chaos of the Echoes and expel it at the Shereeker ship. However, a Shreeker knocked the Doctor away. As it taunted Gabby, Gabby grabbed the screwdriver and used it to finish the calculations, destroying the Shreekers and their ship. The Echoes flew away, thanking Gabby for freeing them. (COMIC: Echo)

After a brief trip to a planet going through a "rainy season", the Doctor took Gabby to the TARDIS's Laundro de-mat to get their clothes cleaned.

After he received a cloaked signal on his sonic screwdriver, the Doctor used the GPS on Gabby's phone to pinpoint the signal, and learnt it was from an auction in the city. While Gabby went to meet with her friend, Cindy Wu, the Doctor attended the auction, where he became suspicious of a mysterious artefact that had already been auctioned off. As he attempted to send a message to UNIT to stop the auction, the Doctor was attacked by Cleopatra Hunsicker, who had noticed his suspicion and demanded his help in acquiring the artefact. The Doctor agreed and the two tracked the artefact to an apartment in the east upper side of Manhattan, where they found it was in the possession of Dorothy Bell. Cleo took control of the artefact and revealed it was used to regress age, using it to regressing Dorothy's assistant, Vivian, to a baby. When the Doctor tried to stop her, Cleo used the artefact on him, regressing him back into his previous incarnation.

Dorothy fought for control over the artefact with Cleo, breaching the time field and causing a burst of energy that knocked everyone out. Cleo awoke first, and escaped with the artefact. The Doctor woke up to find that his and Vivian's ages had been restored, but Dorothy was dead. Vivian revealed that she was aware of the artefact's properties and had hoped to use it to preserve Dorothy's life. Dorothy's body, which was still connected to the artefact's power field, suddenly began levitating as Gabby and Cindy entered the apartment, having tracked the Doctor via Gabby's superphone. Dorothy's body let out pulses of energy, and when it stopped, she had been regressed in age and had powers of matter transmutation. (COMIC: The Fountains of Forever)

Having become a quantum harvester, Dorothy flew away St John's Hospital to use her new powers to build the hospital's new wing, with the Doctor, Gabby and Cindy in close pursuit. As Cindy tried to talk to Dorothy, the Doctor was approached again by Cleo, who had brought her associates, Erik Ulfriksson and Hanif, from her religious cult with her. They were under the belief the artefact could be used to communicate with the gods. Afraid of the mentioning of gods, Dorothy flew away, taking Gabby with her, while the Doctor, Cindy and the cult decided to team up to track her down.

They tracked Dorothy to the Empire State Building, where she was using her powers to rebuild the city, while a mysterious force captured the Doctor, Cindy and the cult and sent them to a vessel. The Doctor deduced that the "gods" were the Osirans, and that the vessel was a remnant of their civilisation. The force, calling itself "the Seeker", detected Gabby and Dorothy and beamed them to the vessel as well, but then dispensed the Doctor and Cindy back on Earth. Cindy demanded that she be allowed to help, so the Doctor reluctantly agreed to take her to the TARDIS. They travelled to the Osiran mothership, which was where the vessel was located. They exited to find Gabby, Dorothy and the cult frozen and suspended, and were confronted by Anubis. (COMIC: Spiral Staircase)

Anubis's servant deduced that Dorothy, with her new powers, was the manifestation of the key of Horus, and Anubis revealed that he was trying to build a gateway to follow his fellow Osirans to a four-dimensional universe. The Doctor, however, knew that the gateway would create a catastrophic ripple effect that would destroy N-Space. Erik, feeling betrayed from his beliefs, attacked Anubis, and the servants responded by killing Hanif. The Doctor healed Anubis of his injuries in a bid to make him see sense, but Anubis still planned on going through the gate. As the misalignment of the circle of transcendence and the mothership widened, the Doctor finally persuaded Anubis to delay his journey by reminding him he had defeated his father, Sutekh, and that he was nothing like him. Anubis agreed to delay his journey by five thousand life cycles, and Dorothy decided to stay behind with him. The Doctor returned Cindy, Cleo and Erik to Earth and set off for further adventures with Gabby. (COMIC: Sins of the Father)

The Doctor and Gabby visited 1923 Paris, where they thwarted a Cyberman plot to raid the French Gold Reserves. Passing a cafe in the aftermath, the Doctor asked Gabby to order some crepes while he disposed of a leftover Cyberman head. Returning to the café, the Doctor ran into his eleventh incarnation and they both met the Twelfth Doctor. When the three Doctors barged into the café to confront each other, Gabby and the other Doctors' companions, Alice Obiefune and Clara Oswald, explained what an alternative Gabby from a bad future had said and the six attempted to plan a way to avoid the original timeline. 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, while the Tenth Doctor and Gabby ran to the city's environmental unit. When the Twelfth Doctor found his alternate self to powerful to fight alone, he summoned the others to help him. 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 reprogramed the dimensional controls to return the Voord to the main universe. After Clara apologised to him, the alternate Twelfth Doctor agreed and let history take its normal course, regressing the Voord and Marinus back to their primitive evolution. The deed done, the Tenth Doctor spoke his regret at taking the Voords' development from them, and the Eleventh Doctor said he would arrange for them to receive support and advice from the wider community of species.

Back in Paris, the six considered eating at the café, until they saw the Ninth Doctor and Rose Tyler seated inside, with the Tenth Doctor agreeing when his twelfth incarnation theorised that the Ninth Doctor had been left out of the plot due to there being no timeline where he was "anything but fantastic." The groups departed, with the eleventh and tenth incarnations aware they would lose their memories of the event, but that Gabby and Alice would not. (COMIC: Four Doctors)

The Doctor and Gabby visited the planet of Wupatki, a world in which humans lived and worked with the alien Shan'tee, perceived as living music. The Doctor took Gabby to the Presley Foundation to meet one, but they found that the Shan'tee were succumbing to a plague threatening their extinction and mutating them into beasts. The Doctor found that the source of the plague came from an Earth song transmitted through the network. Upon discovering this, thousands of Bovodrines came stampeding towards the foundation centre. He rushed off to shut down the source of the signal, leaving Gabby in the centre as the Bovodrines closed in. On Waystation Terra, the Doctor located the original song and used it to cure the Shan'tee, returning Wupatki to its blissful state. However, as he and Gabby set off in the TARDIS, they received a message from Anubis, who reminded the Doctor he was still waiting for a solution to return to his universe. (COMIC: The Singer Not the Song)

The Doctor and Gabby next travelled to the Pleistocene era, where they were captured by antigrave discs and registered as "undesirable". They were dropped to the ground, where the Doctor cushioned Gabby's fall, but was knocked unconscious. He awoke to find himself in the company of a healer named Munmeth. Munmeth told them that the discs had attacked and abducted his clan, and the Doctor and Gabby joined him to help. They arrived to find the clan had been taken, and the discs attacked them again and took them. Gabby fell from hers but was rescued by a nearby ship. The Doctor and Munmeth were deposited in various environments and confronted by various others, who were being forced to fight them. The Doctor deduced that the plan had been orchestrated by the Monaxi, a race seeking to sell the prehistoric humans. He confronted their leader, Iktra, who was overpowered by the humans and a group of bounty hunters who had rescued Gabby. Iktra, however, refused to concede defeat and summoned his true employers within a time bridge, sucking everyone in and away. (COMIC: Medicine Man)

The group were warped into a cosmic death match in the Arena of Fear and had their memories manipulated to repeatedly fight. The Doctor and his party, however, avoided the manipulation by undergoing a voluntary sensory retreat to retain their minds. Following clues left in Gabby's sketchbook, Jack Harkness, Cindy, Cleo and Erik entered the death match and allowed the Doctor to regain his senses. They encountered the true employer of the Monaxi, Mister Ebonite, who revealed he was abducting the humans for their life energy. As the death matches went on, the Doctor assisted his friends in retaining their memories to avoid going to battle. Gabby and the bounty hunters, who had been captured and possessed by Ebonite, attacked them to gain their energy. The Doctor, however, managed to bring Gabby back to her senses by showing her the Shan'tee's musical portrait of her. With her remaining power, Gabby attacked Ebonite, causing him to activate an emergency scale change, revealing that they had been shrunken in a miniature environment beneath the Rockefeller Center. Ebonite split into multiple tiny clones, which ran off, vowing revenge. Munmeth decided that his remaining Neanderthal kind could live out in another world, and the Doctor suggested to Jack that he start a new group with Cleo and Erik's cult. The Doctor and Gabby left in the TARDIS, deciding to allow Cindy to join them as well. (COMIC: Arena of Fear)

Escapades with Gabby and Cindy
While settling Cindy into the TARDIS, the Doctor began work on a new rift detector. In his tinkering, he accidently "deleted" Cindy's bedroom. (COMIC: Lady of the Blue Box)

Intending to head to London, the TARDIS instead brought the Doctor, Gabby and Cindy to the English village of Dewsbury, where the TARDIS trio learned of a mysterious curse in the town surrounding a witch. Investigating the curse, the Doctor entered a cave, where he discovered the "witch" was a creature that had come through a window into the Time Vortex. He accidentally scared it, causing it to attack the town in a feeding frenzy, stealing people's psyches. Reuniting with his companions, the Doctor worked to dispel the witch by using a time scope to track back the witch's origin point. The witch fused itself with the Doctor's mind, revealing to him that it was the remnants of ancient Gallifreyan children trapped in the Untempered Schism. The witch was then dragged back into the Time Vortex, restoring the residents of Dewsbury to normal, but the Doctor was left haunted by the experience as he and his companions left in the TARDIS. (COMIC: The Wishing Well Witch)

The trio decided to go to New Orleans for a holiday, but the TARDIS's plasmic cohesion came under pressure as it travelled in the vortex, forcing the Doctor to engage its inhibitors. The TARDIS stabilised, but Cindy was transported to another area. The Doctor discovered that the TARDIS was containing miniature bubble dimensions, one of which was containing Cindy, who was being chased by a creature. He ordered Gabby to re-enter the TARDIS into the vortex to break the connection of the dimensions, as he dragged Cindy back in. The Doctor deduced that it had been a deliberate attack on the TARDIS, which Gabby determined could only have been orchestrated by Anubis. The Doctor produced the Eye of Horus in the event that Anubis attacked them again. (COMIC: The Infinite Corridor)

The trio arrived in New Orleans in the "Jazz Age", where they spent two weeks having a holiday. While Gabby and Cindy enjoyed themselves, the Doctor remained withdrawn in the TARDIS, though he would still join them for dinner every night. Encouraging him to have an evening off, Gabby and Cindy brought him to a jazz concert where they discovered that several musicians in the area had mysteriously been losing their ability to play. Investigating, the Doctor and Gabby discovered the Nocturnes were responsible and harvesting the musical abilities to power themselves, having possessed musicians Roscoe Ruskin and Paradisa to harvest their abilities. The Nocturnes used the energy to shape themselves into the form of a giant monster. The Doctor encouraged other musicians to play music to weaken the monster, but it had the result of making it stronger instead. (COMIC: The Jazz Monster)

The Doctor determined that noise amplitude could affect the monster. Gabby used the Wupatki's music box music to weaken the monster, which then collapsed the incubation field. Using powers left over from Ebonite's control of her, Gabby shielded herself, the Doctor and Cindy at the last second, but everyone else in the club was killed. Gabby apologised to the Doctor for keeping the powers secret from him. The Doctor and Gabby travelled to Chicago so that they could stop Roscoe and Paradisa from recording an album while still under the Nocturnes' influence. Using Gabby's music box from the Shan-Tee, the Doctor overloaded the Nocturnes with centuries of music. Fuelled by his love of Paradisa, Roscoe attacked the Nocturnes with his trumpet, overloading and destroying it, but killing himself in the process. The Doctor, Gabby and Paradisa returned to New Orleans for Cindy, who was extremely upset at Roscoe's death. (COMIC: Music Man)

The Doctor dropped Gabby and Cindy off at Sunset Park so that Cindy could recover from Roscoe's death. During this time, the Doctor looked in on Cleo and they shared several adventures together, including attending the Ogrons poet society and visiting the Guild of Unfeasible Mirthcasters. (COMIC: Revolving Doors)

Joined by Noobis
The Doctor spent some time in the Garden of Osiris. While he attempted to help the Seeker seal certain Keyhole Anomalies surrounding the Circle of Transcendence, the Doctor, Gabby, Cindy and Noobis were attacked by a consciousness from another dimension at the last moment that it could have passed through. Placed in a virtual reality, the Doctor slept for several days before waking up beside a fellow-homeless man named Boris. Noting an over-arching building known as the department store, the Doctor decided to travel there with Boris. Along the way, he witnessed first-hand the ferocity of a species known as the Wraiths, who attacked and killed another civilian.

Around the same time, Cindy was able to break free of her reality, causing the Doctor's to slip slightly. He fell from a hanging draw-bridge, although he suddenly could remember Cindy. Preparing to be attacked by the Wraiths, the Doctor was shocked to see his hand snap open much like that of an Auton. Awakening in another reality, duplicates of Cindy and Gabby attempted to sell him a new sonic screwdriver alongside a new TARDIS. However, he was broken by the trance when the real Cindy shifted into the new reality and took control of the faux Cindy. He soon shifted back to his initial world, alongside Boris. The Doctor rushed to the department store, which he recognised as the link between all of the realities.

Stopped at the department store's security gates, the Doctor and Boris were quickly identified as rejects and were chased by security. The Doctor began to lightly wake in the real world, surrounded by dead duplicates of his previous incarnations. Cindy soon arrived and helped him break free using his sonic screwdriver, and they were able to free the rest of the group. Escaping their trapped environment, the crew discovered that they were inside a massive organic red hull which had scanned and duplicated the TARDIS' police box form. The Seeker explained that outside the shuttle only moments had passed since they were attacked, and while the team began to try and decode the situation, the Jade TARDIS grabbed Cindy with one of its tentacles and dematerialised. (COMIC: Breakfast at Tyranny's)

During their travels together, the Doctor, Gabby, Cindy and Noobis encountered fake Cybermen that re-enact the Cyber-Wars, visited a world where fruit was used currency, and also visited the Xenopsychology Library of Aramuko. Noobis decided to take a break from travelling in the TARDIS in order to stay on Aramuko. (COMIC: Vortex Butterflies)

Final escapades with Gabby and Cindy
When the Cybermen allied with Rassilon to take over history, the Doctor was made the Field Marshal of the Last Great Sontaran War Fleet by the Sontaran-Prime after he, Gabby and Cindy were captured by Sontarans at Cosmomart. As the Prime showed the Doctor his fleet, the Cybermen attacked Sontar with CyberKings, using Gallifreyan technology to ambush the Sontarans, with the Sontaran-Prime sacrificing his life to shield the Doctor. While Gabby and Cindy caused a diversion with a Sontaran scout ship, apparently at the cost of their lives, the Doctor commandeered a CyberKing and wired himself into the Cyberiad. Channelling his rage, the Doctor attacked the Cybermen until a Cyber-Ark appeared and began a planetary conversion, only for everything to revert back to normal. Still able to remember the events when everyone else forgot, the Doctor looked on suspiciously as Gabby and Cindy shopped in Cosmomart. (COMIC: Supremacy of the Cybermen)

The Doctor, Gabby, and Cindy visited the road to Parthia in 111, and stopped the Zoroniss from taking over the world. During this adventure, a word-rider flew inside the Doctor's body. (COMIC: The Long Con)

After hearing that his old friend Plex had passed away, the Doctor went to pay his respects on Plex's adopted home planet, where he, Gabby and Cindy found a message Plex had left for the Doctor, asking him to erase him from the memories of his clones so they could grow as a species without his influence. (COMIC: The Promise)

While telling Gabby and Cindy of his past adventures, the Doctor saw his third incarnation being consumed by white energy as their TARDISes briefly merged, forcing his TARDIS to use an emergency temporal displacement and encountered a temporal funnel and extreme gravitational stresses that pulled the TARDIS to Poseidon, a space station mining energy from Hades' Helix in the late Expansion Era. As they gained entry by pretending to be inspectors, the Doctor fixed the shields of the station, just as it was attacked by Cybermen that were possessed by the same white energy he saw attacking the Third Doctor. As the crew of Poseidon evacuated, the Doctor realised there was an intelligence behind the attack. As they returned to the TARDIS, the Doctor noticed that the white energy had begun consuming the local space, and he, Gabby and Cindy left as the station self-destructed, but were caught in one of the white energy's tendrils, dragging the TARDIS off-course. The TARDIS merged with the that of the Twelfth Doctor at St Luke's University in 2017, where the Tenth Doctor was reunited with Jenny. Strategising with his future self, 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 Gabby, Cindy, Bill Potts and Nardole, 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 disruption to 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, but remaining behind in the Void. The Tenth Doctor, Gabby and Cindy were then returned to their proper place by the Ninth Doctor. (COMIC: The Lost Dimension)

Following a distress signal to a 31st century spaceship in the Spiral Head Nebula, the Doctor, Gabby and Cindy found themselves in the middle of an Earth-Corp weapons test of a Kirlian Field Harness. After nullifying the test and bringing the lone survivor, Erica Kelly, back to Earth, the Doctor, Gabby and Cindy witnessed Kelly make the first step towards changing Earth-Corp for the better. (COMIC: The Ghost Ship)

While disarming an alien bomb in the British Museum, the Doctor fell into a booby trap and was poisoned by Praxis gas, but he was saved when Gabby and Cindy called upon Nurse Elizabeth Garrett Anderson to concoct a remedy. In return for her treating him, the Doctor took Anderson to the Worshipful Society of Apothecaries to begin her career as England's first female doctor. (COMIC: Nurse Who?)

Helping Majenta
The Doctor encountered time-travelling businesswomen Majenta Pryce when he went undercover as a medical doctor at the Thinktwice Orbital Penitentiary, where she had been imprisoned after being arrested for her "Hotel Historia" business. However, the harsh regime and crude psychological methods of the prison left Majenta with no memory of the Doctor or her life before their first meeting. The Doctor restored Majenta's memory of him, but could not restore anything else beyond their first encounter. Together, they discovered that Thinktwice was being used by the Memeovax, who fed on the prisoners' memories. When one of the Memeovax tried to invade Majenta's mind, she unleashed a blast of power that destroyed all the Memeovax in Thinktwice Prison. Afterwards, the Doctor was ordered into helping Majenta to resolve her memory issues, reluctantly taking her aboard the TARDIS. (COMIC: Thinktwice)

Trying to take Majenta to the healing world of Panacea, where he planned to solve Majenta's memory problems, the Doctor instead landed the TARDIS in Stockbridge, where he was reunited with Maxwell Edison and saved Stockbridge village from the Lokhus of the Zytragupten. After this, the Doctor once again asked Maxwell to travel with him. Maxwell declined, instead opting to protect Stockbridge from aliens. (COMIC: The Stockbridge Child)

The Doctor and Majenta arrived at an apparently abandoned house on the edge of the Proxima System. The Doctor discovered a holographic party run by a digitised avatar of Wesley Sparks, founder of Sparktech. As events from decades before replayed in holographic form, the Doctor learnt that Majenta had been a guest at the party as Wesley's fiancée. The real Majenta explored the house. She came upon the real Wesley Sparks, now a desiccated cyborg who had gone insane as he preserved himself with bionic parts, waiting for Majenta to return from "pressing business". He attempted to force Majenta into marrying him, but she was saved by the Doctor and Wesley's avatar, still the dignified host and gentleman he had been. Damaged in battle saving Majenta, the avatar begged Majenta to remember their lives together. Majenta tearfully broke down and embraced the avatar as it died. (COMIC: Mortal Beloved)

Still trying to take Majenta to Panacea, they got side-tracked and landed in Sydney, where they were taken into custody by UNIT's Australian branch by Majenta's old confidante, Fanson, disguised by a perception filter. Fanson was now in the thrall of the Skith Leader, who was secretly helping Fanson infiltrate the UNIT operation. Majenta was captured by the Skith General's rival forces, who were surprised to find they were unable to access her mind. The Skith elected her as the perfect pilot for their prototype timeship, the SKARDIS, and converted her into a Skith Queen. While she was in this form, the Doctor convinced her to turn on the Skith and help UNIT destroy their ship. As the Skith ship fell, Fanson revealed that he was responsible for erasing her memory to spare her from agony. Fanson died from injuries sustained at the hands of the Skith General, and the Doctor and Majenta fled, finally beginning to warm to each other. (COMIC: The Age of Ice)

The Doctor and Majenta next visited New Old Detroit, a planet in the Proxima System, where they solved the final case of Johnny Seaview and wrested control of the World Bomb from a corrupt Alpha Centauran. The Doctor triggered the World Bomb, transforming the slums of New Old Detroit into a world mapped on his memories of England. (COMIC: The Deep Hereafter) The Doctor next took Majenta to Graveworld 909, where they reset Prespero, the automated guardian of the planet who had taken away the population's speech following a galactic war. (COMIC: Onomatopoeia)

After that, the Doctor took Majenta to see the play The Mousetrap. In the London Underground, they found "ghosts" saved by a being known as Mnemosyne. After they defeated Mnemosyne, and he received another prophecy about his approaching demise, the Doctor decided to stick to his "no companions" rule and finally take Majenta to Panacea. Before he could take her there, a fleet of ships surrounded Earth, having finally tracked down him and Majenta. (COMIC: Ghosts of the Northern Line)

Majenta and the Doctor tried to escape in the TARDIS, but failed when Intersol launched a tractor beam. The Doctor was captured and tortured by Finn Dargo and learned that Majenta was a member of the Crimson Hand, a highly dangerous criminal organisation. Majenta was mind-probed by Intersol's computer, Justice, and then attacked by her old cellmate, Zed. The Doctor convinced Zed into becoming his ally, helping him escape and save Majenta, just as the Crimson Hand arrived, having followed the TARDIS around the universe. Her memories restored, Majenta revealed the Hand had use of the Manus Maleficus which five individuals could use to rewrite the universe. They killed most of Intersol's staff and took Majenta over again. As she was taken over, she used the Manus' power to teleport the Doctor and his TARDIS in a pocket dimension, making her Crimson Hand friends believe that she had turned the Doctor to ashes.

After the Crimson Hand members seized control of the whole universe with the Manus, Majenta restored her homeworld of Vessica, however the Hand's changes to reality caused the Morass to begin to consume the universe, starting with Vessica, prompting Majenta to bring the Doctor back into existence. They planned to infiltrate the Hand's headquarters, with Majenta distracting them whilst the Doctor used a piece of the Manus she'd given him to shut it down and revert the Hand's changes. After resisting the urge to use its power to bring back everyone he had lost, the Doctor attempted to shutdown the Manus but it rejected him, revealing Majenta had tricked him. Whilst the Hand gloated, Majenta entered the Manus and used it to finally destroy the Crimson Hand, at the cost of her life. The Doctor jumped after the Manus as it withdrew to the Morass and used it resurrect her and place her in the restored New Old Detroit. With the Manus linked to his mind, as long as the Doctor remembered her she would stay alive. On good terms, the Doctor and Majenta parted. (COMIC: The Crimson Hand)

Meddling with time
The Doctor arrived in London in 1889 and encountered H.G. Wells and Jonathan Smith. They were pursued by two agents of Torchwood, Robert Lewis and Eliza Cooper, who were seeking to capture the Doctor. The Doctor and Jonathan escaped to the TARDIS where Jonathan revealed himself as a time traveller from the 51st century, seeking to prevent the Fourth Doctor's upcoming defeat of Magnus Greel. The Doctor tricked Jonathan by dematerialising the TARDIS without him, leaving him for Robert and Eliza who mistook him for the Doctor and captured him. The Doctor reunited with Wells afterwards, encouraging him to write The War of the Worlds. (COMIC: The Time Machination) The Doctor attended a celebrity party in 1926 Hollywood, where he met Archie Maplin, a young actress named Emily Winter and a runner named Matthew Finnegan. He drew the attention of Maximilian Love and Mr Leo Miller, two Terronites, who planned to transfer the hopes and dreams from young actors, such as Maplin and transplant them into themselves, because they were actors on Terron V. Offering himself for Maplin's safety, the Doctor's memories were too much for them, and inadvertently set fire to the building. The Doctor got them all safely out the building before it exploded. Outside, they saw Miller escaping, but were eventually arrested by the police. As the Doctor headed back to the TARDIS, Matthew and Emily asked if they could join him, but he refused. However, as he was about to enter his ship, a temporal vortex opened up. From it emerged Judoon and a Shadow Architect, who arrested the Doctor for interfering in a fixed points in time. (COMIC: Silver Scream)

The Doctor was placed on trial by the Shadow Proclamation for saving Emily's life when she should have died in the fire. Krillitane leader Lassar was the Doctor's prosecutor and the Advocate was defence, but the Advocate was apparently killed. The Doctor was sentenced to imprisonment on Volag-Noc, and, during the journey, met a Draconian, a Sontaran and an Ogron. The Doctor's party took control of the ship. After this, the Doctor learned that his trial was set up to uncover Lassar's plot, but he also found out that "Lassar" was from a shapeshifting race called the Gizou, in disguise. The Doctor returned to Hollywood to collect the Terronite Transference machine, and used it to extract memories from his mind. He also decided to break his "no companions rule" by inviting Matthew and Emily to travel with him. (COMIC: Fugitive)

The TARDIS was invaded by aliens called the Acari led by the Advocate, and were intent on killing the Doctor. The breach of the TARDIS by the Acari spaceship forced the TARDIS interior to rearrange itself, displacing the console room, and risking implosion. Since the Doctor was psychically linked to the TARDIS, the trauma of having the Acari ship aboard caused the Doctor to undergo mental instability. The Advocate placed doubt into Matthew's mind about the Doctor's morality by urging him to read the secret diary previously belonging to Turlough, as a being called the Tef'Aree appeared to Emily in the TARDIS. Emily helped the Doctor save the ship, and the Acari ship separated from the TARDIS, but not before the Advocate stole the Terronite technology.

The Doctor was summoned to Greenwich Park by Martha Jones (COMIC: Tesseract) and Captain Erisa Magambo, working on behalf of UNIT, and claimed that the trees were attacking people. The tree trunks were marked with Enochai symbols, a language invented by mathematician and magician John Dee to converse with angels. The Doctor realised these "angels" were trapped beneath the observatory, but emerged through the trees in the park. The Doctor headed into the passages beneath the park to communicate with the "angels". In actuality, the aliens were waiting in suspended animation for the Doctor to free them. Believing the Enochai's story, the Doctor set them free, but it was a trick, and they were free to take over all of the trees and conquer the Earth.

The Enochai realised the Doctor didn't remove the force field trapping it, so they threatened Emily. The Doctor and Emily escaped, but plunged down a hidden shaft into an ancient cavern where they discovered a stripped down colony ship containing thousands of Enochaia in stasis. The Advocate arrived and opened the stasis pods, releasing the Enochai. The Enochai trapped Central London in a force field. The Advocate appeared to Martha and proposed a way of ending the crisis, by striking at the Enochai ship and planting a bomb in it. Martha found Emily and the Doctor, and they confronted the Advocate, but Magambo refused to allow the Doctor time to develop an alternative solution to the Enochai threat and insisted on following the Advocate's plan. When he resisted this option, she arrested the Doctor.

Martha and Emily rescued the Doctor. The Doctor arrived and launched the Enochai ship into space, which drew all the Enochai up with it, and removing the force field. The Advocate's bomb was no longer needed, but the countdown was accidentally started and the ship would explode, leaving a gardener called Mr Crane trapped inside, but the Doctor could do nothing to save him. The Advocate used Crane's death to finally destroy Matthew's faith in the Doctor and Matthew elected to leave the Doctor, and travel with the Advocate instead. After solving the crisis, the Doctor and Emily departed from London. (COMIC: Don't Step on the Grass)

After several adventures in the TARDIS, the Doctor and Emily arrived at the Shady Grove Rest Home in the 21st century where an old man named Barnaby Edwards was celebrating his birthday. Although the Doctor didn't recognise him, Barnaby insisted he travelled with the Doctor when he was a young man, and that the Doctor had given him an envelope with the instructions of guarding it. Barnaby returned it to the Doctor before dying. Inside the envelope were the charred remains of Turlough's diary and a warning that Matthew was in danger. The Doctor and Emily then headed off to find him. (COMIC: Old Friend)

While exploring a war-torn planet, the Doctor and Emily encountered Torchwood agents Robert Lewis, Eliza Cooper, Professor Alexander Hugh and Annabella Primavera from 1906 Oxford University, who were testing a time machine created from cannibalised alien technology, which inadvertently transferred them through time and space to the planet. Their group was captured by inhabitants of the planet, called the Soul Free, who had been fighting with other inhabitants called Terror Farmers for thousands of years. The party were led to a temple called Kol'Ne Wah by Lau'Tan, the Gizou who impersonated Lassar during the Doctor's trial by the Shadow Proclamation and had been working against the Advocate since the trial.

They were attacked by the Terror Farmers, causing Annabella's death. Lau'Tan disguised himself as the Doctor and was captured with Emily. The Doctor led the remaining group to the temple, where he discovered a lost expedition, who made contact with the Tef'Aree, who Emily had encountered in the TARDIS during the Acari incursion, and were in fact humans given a terraforming device with which they hoped to make the colony planet self-sufficient. After this discovery, the Doctor realised that the name "Terror Farmers" was a corruption of Terra Firma.

The Doctor discovered that the Advocate planned to use Matthew's human DNA to reactivate the terraforming device which would wipe out the whole planet. Matthew and the Advocate teleported up to the orbiting terraforming device and the Doctor followed in the TARDIS. As the Advocate tried to get Matthew to activate the terraforming device, he revealed his true allegiance was with Lau'Tan. She shot Matthew, and used his palm to activate the device. The conflict on the ground between the Terror Farmers and the Soul Free was brought to an instant end as the device began to destroy everything on the planet.

Robert Lewis was destroyed by the terraforming beam, while Emily was saved from the blast by Turlough's diary. The force field around the colony ship couldn't be repaired, but Lau'Tan realised it could be replaced. He transformed himself into a device to replace the damaged component and restart the shields while Emily got everyone safely inside. Matthew distracted the Doctor, grabbed the Advocate and deactivated the terraforming controls, but it backfired. Both Matthew and the Advocate died instantly, but both their minds merged into a fifth-dimensional being called Tef'Aree. The Tef'Aree previously gave the Earth colonists the terraforming technology, revived the Advocate and had manipulated events surrounding the Doctor so that he could bring about his own creation. When the Doctor tried to scold the Tef'Aree, it vanished. Before deactivation, the terraforming beam destroyed the force field equipment, in turn, destroying Lau'Tan. However, many of the Soul Free and Terror Farmers were saved by his action, being protected by the force field. Eliza elected to remain and help to rebuild the planet, and build diplomatic relations between both factions. Upon discovering that the planet was called Terron V, he realised that both groups would unite, and eventually become the Terronites, who the Doctor fought in the form of Maximilian Love and Mr Leo Miller in Hollywood in 1926.

The Doctor took Professor Hugh and Emily back to 1906 Oxford in the TARDIS, where he explained that Annabella Primavera, like Emily, was a fixed point in time, but while Emily was supposed to have died, Annabella was supposed to have lived. Therefore, Emily had to live on Earth, and take her place to mend the Web of Time. Before she departed, Emily gave him Turlough's scorched diary, and the Doctor left for a trip to Mars. (COMIC: Final Sacrifice)

Becoming the Time Lord Victorious
On his trip to 2059 Mars, the Doctor met the crew of Bowie Base One, led by Adelaide Brooke. Knowing the crew would die in one of the most crucial events in humanity's expansion through the universe, the Doctor learned that the crew died due to the Flood, which possessed six of them. He was initially unwilling to interfere in events due to his belief that the event was a fixed point in time and made to leave multiple times, but he became continuously integrated in the events of Bowie Base One and even confessed his foreknowledge of how the timelines played out to Adelaide. During a final attempt to leave, the Doctor was caught in an explosion and, reflecting on his status as the last Time Lord, declared himself the "Time Lord Victorious" and elected to save Adelaide and the two surviving crew members and take them back to Earth. (TV: The Waters of Mars) The TARDIS believed this was his attempt to "teach [Death] a lesson". (PROSE: What the TARDIS thought of "Time Lord Victorious") Although confident that the Laws of Time were his to govern, Adelaide committed suicide after stating her fury at the Doctor's interference and scolded him for thinking himself above obeying history's course. The events of Bowie Base One shaped the same timeline, but with Adelaide dying on Earth instead of Mars and the events that happened on Mars being made public knowledge by the survivors. Distraught at the results of his actions, he saw a vision of Ood Sigma appear before him, and fled into the TARDIS, determined to avoid the crisis Sigma was heralding. (TV: The Waters of Mars)

Fleeing to the Dark Times through the Time Fracture that his alterations to history had created, (PROSE: What the TARDIS thought of "Time Lord Victorious") the Doctor, wanting some peace and quiet, found himself on the planet Andalia and was intrigued by a demonstration of Professor Hana Fallomax's Lifeshroud that claimed to cheat death. He saved the demonstrator, Estinee, from being attacked by Brian the Ood, who had been contracted to test the technology's efficacy by Ambassador Verv-Hoondai Chalskal. The Kotturuh arrived and issued their judgement on the inhabitants of Andalia, and kidnapped Estinee, but the Doctor and Brian followed them to Mordeela to rescue her. They witnessed her being rescued by Fallomax and fled from revenants back to the TARDIS, but the Kotturuh, angry at his interference in their Design, marked the Doctor with a date on Andalia in a few days.

Rufusing to be intimidated, the Doctor sought out Fallomax to help her Lifeshroud project and, even after he learnt them to be useless and that Estinee had an inexplicable natural immunity to death, agreed to help her make a working model without the crystals needed from Mordeela. With Chalskal's funding, the were able to make a Lifeshroud with a six hour operating time, which they tested on Chalskal when Brian outed him as a fraud. Brian convinced Chalskal to hand over his mercenary forces for the Doctor's war with the Kotturuh, while the Doctor refocused his efforts on reverse engineering the Kotturuh's power to render them mortal as well, taking Estinee and Fallomax back to Atharna to finalise his research. While he initially wanted to only grant them an ordinary lifespan, after the Kotturuh influenced Estinee to send the TARDIS forward in time to his appointed date and also kill Fallomax, and she killed herself to save him, the Doctor chose to give the Kotturuh a lifespan of just fifteen minutes to wipe them out, believing this would stop death at its source and rewrite time for the better as he declared himself the "Time Lord Victorious" again.

Adopting the ceremonial Time Lord robes of the Prydonian Chapter, the Doctor returned to his fleet for a final charge against the Kotturuh by sealing their power source at Mordeela. However, his fleet was confronted by his eighth and ninth incarnations, who arrived above Mordeela in a Dalek saucer and a Vampire coffin ship respectively, and attempted to convince him to stop. Dismissing them as Kotturuh illusions, the Doctor ordered his fleet to fire on Mordeela (PROSE: The Knight, The Fool and The Dead) destroying the planet. In the ensuing Battle of Mordeela, the Tenth Doctor's fleet was either destroyed by the Daleks and the vampires or forced to flee. While he was able to negotiate a cease fire with his other incarnations in a telepathic contact, the Eighth and Ninth Doctors were unable to make their forces stand down, and the Tenth Doctor escaped in his flagship, the only surviving ship of his fleet, in the confusion after he managed to seal the gateway to the Kotturuh's realm. (PROSE: All Flesh is Grass) Afterwards, he connected the TARDIS to the ship's damaged engines to supply them with power, (AUDIO: The Minds of Magnox) and named the flagship the HMS Donna. (PROSE: All Flesh is Grass)

Wanting to do some good, the Doctor wandered alone to a desert planet. Brian tracked him down and saved him from being fed on by ghosts, who had tricked the Doctor into believing he had managed to save their species. (COMIC: Tales of the Dark Times) With Brian in tow, the Doctor headed to Magnox to finding out if he had truly done the right thing in taking out the Kotturuh. While Brian went off to explore on his own, the Doctor received help from Bibliocrat Peschell in finding the Council of Minds to ask his question, but the Minds laughed at his question and refused to answer. When the Kotturuh arrived on Magnox demanding the Minds tell them how to defeat the Doctor, Brian killed the Minds to fulfil a recent contract, and the Doctor used their technology to temporarily halt the Kotturuh before they could attack Magnox, giving him time to send out an evacuation order, taking the Magnoxians to Islos in the flagship. (AUDIO: The Minds of Magnox)

When Brian convinced him to acquire new weapons for their ship, the Doctor took him to Entranxis to meet the Death Brokers, who showed them a vampire they had captured named Ikalla, but the Eighth and Ninth Doctors interrupted the meeting to liberate Ikalla. The Daleks and the Kotturuh then attacked, and the Tenth Doctor returned to the Donna with Brian and the Eighth Doctor. As they left the planet, they witnessed the Daleks destroy the Kotturuh ship before the Ninth Doctor arrived with Ikalla, but they quickly left to help the Kotturuh. Searching for a way to stop the Daleks, the Eighth and Tenth Doctors found a damaged coffin ship the Daleks had attacked and learnt from the surviving Bloodsman that they had captured a Great Vampire, and infiltrated a Dalek saucer with Brian the Ood and Gelsin the Bloodsman, where the Tenth Doctor and Gelsin discovered the Dalek Prime Strategist and Dalek Scientist experimenting on the Great Vampire, extracting its DNA and adding it to a Dalek mutant to create the Dalek Symbiont. The Strategist revealed it knew the Doctor was there, but the Doctors escaped with Gelsin in the confusion caused by the experiment draining the saucer's power, leaving Brian behind.

The Doctors used the Donna to destroy a Dalek scout ship sent to attack Birinji and reunited with the Ninth Doctor in a biodome on the planet, where they were introduced to Inyit, the last of the Kotturuh, and the Tenth Doctor realised the Kotturuh were not the great evil he had believed them to be. Brian contacted the Doctors to inform them he had discovered the Daleks planned to destroy Gallifrey before the rise of the Time Lords, and the Doctors together mounted a defence of Gallifrey, with the Tenth Doctor rescuing Brian from the Daleks. However, even with the Free Undead, the Doctors were unable to stop the Daleks' army of undead drones with Symbiont DNA, so prepared to collide the flagship with the saucer, in the hopes of the ensuing paradox wiping out the Daleks, but were prevented from doing so when Inyit used her final judgement to wipe out the Symbiont and the hybrids, ending the Daleks' assault as they panicked, fearing the judgement may spread to pure Dalek DNA, allowing the Eighth Doctor to sneak aboard with the aid of a Bloodsman. There, he used a remote detonator to trigger an explosive Brian had left in the saucer's engine room, forcing the saucer into the Time Vortex and away from the Dark Times. As they left the Donna to burn up in Gallifrey's atmosphere, the Ninth and Tenth Doctors returned to Birinji, only to find Inyit had already passed away, with the Tenth Doctor finally expressing his remorse for what he had done. The Doctors reflected that death would now spread entirely naturally and the Tenth Doctor agreed that, though he approved of the change, he had gone too far and would not rewrite history any further. After Brian decided to stay with the Free Undead, who were settling on Birinji, the Tenth Doctor departed the Dark Times alone. (PROSE: All Flesh is Grass)

Delaying his fate
Trying to avoid his future, the Doctor visited the Magellan World and saw a door to the Cathedral of Contemplation. He went to the Cathedral and, out of curiosity, broke a barrier intending to stop timelines to cross and bumped into his fourth incarnation. As a punishment for his behaviour, the Abbess confiscated his sonic screwdriver. When the Daleks attacked the Cathedral, the two Doctors brought the pilgrims to safety. The Tenth Doctor tried to prevent his earlier self from confronting the Daleks, but he was unsuccessful, so he stayed to help the pilgrims get out of the place by making them crawl through the air ducts, after Kivell had given him back the sonic.

As he was doing that, he had a vision of the Fourth Doctor being imprisoned by the Daleks and forced to try and move the Cathedral. He reached him and joined him to the console, so that the combined efforts of their two minds could be successful in moving the place through space and time. The two Doctors first arranged for the pilgrims to get out safe and alive, then directed the time corridor to Earth, 5,000,000,000, thus leading the Daleks to their destruction. Released by Jora, the two Doctors then managed to escape and trap the Dalek Supreme in the collapsing cathedral. As he prepared to leave in his TARDIS, the Fourth Doctor encouraged his tenth incarnation to find a new companion, inspiring the Tenth Doctor to continue delaying his trip to the Ood Sphere. Afterwards, the Doctor stayed at the Festival of the Phosphorous Carousel. (AUDIO: Out of Time)

The Doctor noticed the Time Agency placing Galaxy L-10 in a time lock, erasing it from time, and went to confront them. Time Marshal Barnes refused to listen to his pleas and had him arrested, however he quickly escaped and discovered the device they'd used to achieve the erasure, the Hourglass, which Barnes revealed was based on a Time Lord weapon, the "galaxy eater" and she had erased the galaxy on its prediction there was a 96% chance of time travel experiments there destabilising the universe. She had him imprisoned again but feared he'd still manage to reverse her success and ordered his placement in a time lock. The Doctor appealed to the Hourglass, knowing it would have a conscience from the weapon it was based on, and it took him inside it's core where he could further modify it to get grant it more autonomy and reversed the erasure of L-10. As the reversal occurred, he confronted Barnes again and she ordered an Agent, Alison, to destroy the Hourglass before the reversal was complete. He convinced Alison to disobey and decided to name the galaxy after her. He then left with Alison to take her to guide the time travel experiments to avert disaster, warning Barnes that time always won and the Agency would likely disappear one day. (AUDIO: The Shattered Hourglass)

Planning on going to the Majestic hotel in Paris 1922, the Doctor was dragged to 1944 by a temporal anomaly. He went down to the catacombs but remembered his previous excursion there. He relived his previous excursion and the paradox happened to allow the Cybermen to fully invade. Travelling back to the 18th century with his past self, they learnt that the Cyber technology that was part of the legends in the new timeline and found out when to stop their plans. Back in 1944, the Doctor discovered that his TARDIS was missing. (AUDIO: The Gates of Hell)

The Doctor took a pop-up add from the psychic paper, and landed on Thoros-Beta, where the TARDIS landed on an angry Mentor named Gom. (COMIC: Psychic Paper Inc Claims Department)

The Doctor visited 1958 America, where he accidentally activated a piece of "space junk" from a UFO crash, drawing the attention of the Alliance of Shades. Escaping with Cassie Rice and Jimmy Stalkingwolf, the Doctor was attacked by a Viperox battle drone, which was promptly blown up by the United States military. The three were taken to Area 51, where they met Colonel Stark, who dismissed the Doctor's warnings about the Viperox, and attempted to have the Doctor and his new friends mind-wiped. The attempt was unsuccessful, and the trio soon escaped, discovering a small grey alien named Seruba Velak along the way.

They fled to the town of Solitude, where Jimmy was kidnapped by the Viperox. After tracking him down, the Doctor and Cassie found a Viperox Queen before escaping with Jimmy into the desert, where they were confronted by the Alliance of Shades, who were destroyed by Jimmy's grandfather, Night Eagle, and his tribe. Night Eagle took them to Rivesh Mantilax, the husband of Seruba. Colonel Stark captured them all and took them back to Area 51, where the Doctor and Rivesh escaped with the "space junk", which was actually a weapon capable of destroying the Viperox. The Doctor was cornered on the roof by the Colonel, but convinced him to turn against the Viperox, and managed to stop them invading America with the TARDIS. He departed soon after, leaving Cassie and Jimmy with the job of rebuilding the town following the Viperox attack and also encouraged them to start dating. (TV: Dreamland)

The Doctor watched a solar eclipse in the Arctic in 2019, (COMIC: Arctic Eclipse) and, whilst in 4041 Washington DC, encountered the Klytode, and stopped him from gaining presidency for Earth by turning his invasion force of androids against him. (COMIC: Return of the Klytode)

The Doctor stopped Larry Haxton from exploiting a stranded Thrunn creature in one of his film productions, (COMIC: Creature Feature) and saved a space frontier town called Dustville from a beast. (COMIC: Mudshock)

Trapped in the past
Whilst visiting Bury St Edmunds, the Doctor suddenly found himself transported to a crashed spaceship on Mira, where he encountered Anya Kingdom. Once he convinced her of his identity, he discovered she was part of a Space Security Service team investigating the crash, discovering that Visians had killed the survivors and were picking off Anya's team. They were saved by Mark Seven and they escaped back to the retrieval team's ship. Mark explained he was currently investigating George Sheldrake, who was preparing to unveil his time tunnels to the public. Concerned about the risks of mass time travel and wondering if Sheldrake was connected to his abduction, the Doctor agreed to help. (AUDIO: Buying Time)

On Earth, the trio tried in vain to access Sheldrake's building and encountered a pastor, in actuality the Nun in disguise. At the SSS headquarters, the Doctor was disturbed when surveillance of Sheldrake revealed he had a piece of Gallifreyan technology. Whilst Anya and Mark went to request a warrant to search Sheldrake's building, the Doctor was attacked by the Nun who stunned him and imprisoned him in her TARDIS. After impersonating and using the SSS investigation to reclaim her technology, the Nun returned to in her TARDIS and taunted the Doctor, revealing her identity which lead to him realising he had been pulled back to the universe before the Time War. She ignored his warnings about the temporal cataclysm that would unfold if Sheldrake activated his tunnels without her component, and reluctantly took him back to Earth when his warnings were proven right. He used Sheldrake's technology to stabilise the Vortex, however the Nun refused to help him any further and fled. The Doctor used the technology to contact Anya and she came to his aid. He realised he needed to abduct himself from Bury St Edmunds to correct the timeline and resisted the urge to use the time tunnels to save anyone else. The crisis resolved, he prepared to use the SSS' time machine to return to the TARDIS, forgiving Anya as he said goodbye, however a Dalek intercepted his time bubble and destroyed the machine, leaving him stranded. (AUDIO: The Wrong Woman)

The Doctor set off with Anya and Mark to locate the inventor of the SSS' time machine, Arborecc, who was missing, in hopes of him providing a way for him to return to his time. Whilst they were waiting at a spaceport, they were caught in a pirate attack, armed with unusual guns, and fled in an escape pod. They were retrieved and brought to Neptune by Anya's grandfather, Merrick Kingdom. The Doctor encouraged Anya to reconnect with her grandfather and discovered her family history, including her relationship with his former companion Sara. He and Mark discovered Merrick was growing Varga plants beneath his villa, exposing his plot with Abigail Crane to make guns armed with Varga venom which they'd witnessed being demonstrated at the spaceport. Abigail decided to dispose of the Doctor and Mark by placing them in the path of Mechonoids clearing the landscape for colonisation, however the Doctor reprogrammed the Mechonoids and sent them to save Anya from Abigail's flier, which had crashed due to her fighting Abigail. The trio departed Neptune in a spaceship, however Mark fell under an outside influence and cut off the oxygen supply to render the Doctor and Anya unconscious. (AUDIO: The House of Kingdom)

The Doctor and Anya awoke to find Mark had landed the ship and followed his trail to a nearby research centre, ALARC. There the Doctor found Mark originated there and had fallen under the influence of a recall signal, discovering Mark’s personal history. Investigating strange occurrences and a violent death led to the Doctor deducing all the human personnel had long left, being replaced by the androids assigned to mirror them for learning, and that one android was trapped in a loop of fleeing the facility, having their memory wiped by the security shstem and imprinting on native bears, leading to them violently lashing out upon being recalled to ALARC and fleeing again. They discovered the cause of the loop was Mariah Six, who was seeking a way to escape the security system. Mark forced her out of the facility, wiping her memory, and the Doctor and Anya left him to decide what to do with his fellow androids. After he decided to set them free as he had been, Mark revealed he had found a lead on Arborecc and they departed. (AUDIO: Cycle of Destruction)

Tracing Arborecc to Beltos Station, the Doctor, Anya and Mark met its commanding officer, Major McLinn, who denied the scientist had ever been there. Feeling something was amiss, the Doctor went to explore a secret part of the station alone and found makeshift Daleks, which he quickly realised were fakes. McLinn discovered him and had a Dalek guard him. Talking to it, the Doctor realised there was an organic creature inside and opened it’s casing to discover it was the mutated form of Arborecc, to his horror. He furiously confronted the Major on his return, declaring the project would end now, so McLinn decided to resort to having him mutated. The Doctor sabotaged the time engine used for mutation and rallied the fake Daleks against McLinn, so no-one else would suffer as they had. In the ensuing chaos he stole the time engine and found Anya and Mark, who were being pursued by a confused fake Dalek who was formerly Mark’s friend Fliss Keeley. Despite the Doctor’s objections, Mark insisted on trying to talk Fliss down and in her confusion she exterminated him. The Doctor desperately attempted to save Mark, however Anya pulled him back to their ship as the facility was set to auto-destruct by the fake Daleks. (AUDIO: The Trojan Dalek)

Hours after losing Mark, their ship’s warp drive began malfunctioning so the Doctor had Anya pilot it towards the Gruad Confusion intending to attempt to make a time jump using the engine he’d stolen. As he prepared, an future version of the Doctor intervened warning him about flaws in his plan and together they devised a way to safely make entire the ship time jump, stabilising it. He and Anya began to remember an alternate timeline where they arrived in the Confusion and encountered the Lost. They realised their time jump had failed to take the Doctor back to the right side of the Time War, instead putting them in the middle of a skirmish between Dalek and Movellan ships, and their ship received a message: “Hello sweetie”. (AUDIO: The Lost)

Saving Gallifrey
Whilst visiting Queen Elizabeth I in 1562, believing it to be an uneventful year, (AUDIO: The Triumph of Davros) the Doctor was forced to track down River Song to assist him in searching for a fugitive Zygon hive present in the Queen's court. With the help of River, who had expertise in dealing with Zygons, the Doctor discovered that the hive had been knocked onto Earth by a time eddy. After seven hours together with River, during which he bathed with her while fully clothed, (PROSE: The Day of the Doctor) the Doctor tracked them down using a constructed device that went "ding" in their presence, along with many additional features. (TV: The Day of the Doctor) The Doctor successfully infiltrated Elizabeth's court, but was thought to be a spy and was thus sentenced to torture and execution. For several months, the Doctor enchanted both the Queen and his torturer with tales from his travels, and the Queen grew fond enough of him to treat him as a confidant. When it came time for his execution, he was granted a day's pardon for a picnic with Elizabeth, which led him to believe she was a Zygon. (PROSE: The Day of the Doctor)

While having his picnic with Elizabeth, the Doctor proposed to her as a ploy to expose the Zygons, believing his theory to be correct when she eagerly accepted, but discovered that it was his horse that was the Zygon, and also realised that he had just got engaged to the real Queen of England. After the Zygon took on Elizabeth's form, and with his device unable to tell them apart, the Doctor was further perplexed when a time fissure appeared and a fez came through it, followed by the Eleventh Doctor. (TV: The Day of the Doctor) Realising what was about to happen was connected to the outcome of the Time War, (PROSE: The Day of the Doctor) the Tenth Doctor ordered both Queens away and he and the Eleventh Doctor tried to use their sonic screwdrivers at the same time to reverse the polarity of the wormhole, only for the War Doctor to enter the scene. One of the Queens, which the Doctors believed to be the Zygon, returned with royal guards and, after the Eleventh Doctor gave instructions to Clara Oswald, they allowed themselves to be captured and taken to the Tower of London.

At the Tower, the Eleventh Doctor scratched the activation code for Jack Harkness' vortex manipulator into a pillar, which Clara used to save them; the door having been left open. The Queen took them to show them that the Zygons put themselves into stasis in paintings to take over the planet at a future date and revealed herself to be the real Queen who was showing them so that they could defeat the Zygons in the future. Before the three Doctors and Clara travelled there, the Queen had the Tenth Doctor marry her. He promised to return, (TV: The Day of the Doctor) but ultimately abandoned his marriage, causing her to declare him her enemy. (TV: The Shakespeare Code)

Communicating with Kate Stewart with a space-time telegraph, the Doctors, unable to land the TARDIS in the Black Archive, placed themselves into the Gallifrey Falls No More painting after ensuring it went into the Archive and entered the Archive through it. There, the Doctors erased the memories of the humans and Zygons so that neither knew which was which and were forced to negotiate for peace, rather than set off the nuclear warhead to destroy the Archive and London. Seeing how their guilt had brokered peace, the War Doctor decided to go through with using the Moment to end the Time War.

Travelling to the War Doctor and the Moment, the tenth and eleventh incarnations accepted that the War Doctor's actions were inevitable, and decided to assist him in activating the Moment to destroy Gallifrey and end the Time War. Before they could activate the weapon, Clara convinced them to try to find another way, with the Eleventh Doctor coming up with a strategy that involved the Doctors summoning all of their incarnations to freeze Gallifrey in time and lock it in a pocket universe using the stasis cubes, saving it and causing the Daleks to destroy themselves in their own crossfire. After their plan succeeded, and bidding a farewell to the War Doctor at the National Gallery, the Tenth Doctor asked his successor what he was hiding from him, and the Eleventh Doctor told him about Trenzalore before the Tenth Doctor left. The Doctor lost all memory of saving Gallifrey with his other incarnations due to the timelines not being synchronised, (TV: The Day of the Doctor) though he later recalled Queen Elizabeth I being his fiancée (AUDIO: Echoes of Extinction) and subsequently marrying her. (TV: The End of Time)

Final adventures
Arriving aboard a spaceship landing on Orriv, the Doctor was immediately confronted at gunpoint by the crew but talked his way out of being killed. Upon landing, he deduced the world's population had been killed by a psionic pulse and the crew were seeking the source for profit. In the ruins of the city, he found a damaged robot which gave him temporal feedback, leading him to wonder if he'd met it before. When it briefly attacked them, they deduced it was possessed by the creature responsible for the devastation. He explored with Captain Frye and the creature eventually attacked them, revealing it had duplicated to possess the rest of the crew and killing and possessing Frye. Escaping by modifying the captain's scanner into a sonic grenade, the Doctor returned the ship and created a device to contain the creature. He promised he would find it help with the voices tormenting it to draw a line under this death and it allowed him to contain it. The Doctor contained it and returned to the ship, hearing a transmission from his eighth incarnation warning people to stay away from Orriv. (AUDIO: Echoes of Extinction)

After the TARDIS was drawn to December 1859 by a temporal signature, the Doctor found himself unable to interact with the world around him. He encountered Beth Summers, who had inexplicably travelled back in time from 2009 via an advent calendar. Together they discovered that an unknown alien had trapped them both inside the house while he attacked the TARDIS outside. On his instructions, Beth defeated the alien by taking a photograph of him, trapping him in advent calendar, which was in actuality a temporal prison, and freeing her and the Doctor. The Doctor took her back to 2009 in the TARDIS, noticing a pale figure watching him as they left. (PROSE: The Advent of Fear)

The Doctor saved a planet from the Red Carnivorous Maw (TV: The End of Time) and joined forces with top-secret vault employee George Baldwin to stop the Chukwa Fel Interrogators from retrieving a weapon that could wipe out their enemies. (COMIC: Project UFO)

The Doctor began visiting Douglas Henderson throughout his life, because he was secretly a doomsday weapon created during the Last Great Time War. However, when Douglas was middle-aged, the Doctor was forced to take Douglas aboard the TARDIS as a group of aliens had begun hunting him so that they could use him as a weapon. The Doctor used Douglas to drain the aliens' powers, and reset Douglas to allow him to spend the rest of his life on Earth. (COMIC: The Big, Blue Box)

Aboard the TARDIS, the Doctor had a nightmare in which he met a blue-skinned alien that plucked a ball of guilt, fear and anger from the Doctor's chest and sealed it in a drum. He then met his next incarnation, who assured him that they were going to be fine. When the Doctor awoke, he wondered if the TARDIS was syphoning off his bad dreams. (COMIC: To Sleep, Perchance to Scream) He then picnicked with River and the Old Gods, taking time to irritate Thor with a chicken leg. (PROSE: The Day of the Doctor)

Following Princess Cilia's disappearance at the end of the Ulians' war with the Quintani, the Doctor chose to help. However, once the Doctor found Princess Cilia's ship, she wasn't on-board, and the Ulian robots attacked the Doctor, accidentally shrinking him to the size of a doll. The Ulian robots traced Princess Cilia to the approximate area, but only knew that she was in the vicinity of a Christmas tree. They sent shrunken-down versions of their robots, wrapped in Christmas packages to every doorstep on that region of Earth, and inadvertently packaged the Doctor as well.

Mason Valentin, having opened the package early, discovered the Doctor wasn't a doll, but a living being. As the Doctor awoke, he was dazed and suffered from amnesia. After learning of packages delivered all across Mason's area, the Doctor offered Mason to save the world with him. The Doctor and Mason went into Ana Comparetto's house, and the Doctor prematurely awoke a shrunken Ulian robot with the sonic screwdriver. The robot, thinking it had found the lost princess, transmatted Ana back to Cilia's ship. The Doctor and Mason used the robot's "magic wand" to fire a transmat beam to board the ship.

On board the ship, the Doctor released Ana from her cell. The Doctor, remembering what had happened to the princess, told the robots that Ana wasn't the princess, and, though their methods of tracking the princess were scrambled, he could find her easily. The Doctor was brought back to full size and returned Mason and Ana to Earth in the TARDIS. The Doctor discovered Cilia in one house disguised as a fairy on a Christmas tree. Ana told Cilia the war was over, and the Doctor told her to order the robots to send her back to Ulian Alpha. (PROSE: The Doctor on My Shoulder)

The prophecy fulfilled
After meeting with the Ood on Ood Sphere, the Doctor was told that a "shadow [was] falling across creation", which was somehow connected to Donna Noble and her grandfather, Wilfred Mott, something that would bring about "the end of time itself." He also learnt of a plot to resurrect, and failed to stop it. The Doctor discovered the Master living in the wastelands of London. He tried to confront him, only for the Master to evade the Doctor when he reunited with Wilf. That night, the Doctor tracked down the Master once again, only for the Master to be abducted by Joshua Naismith's private army, and, when the Doctor attempted to stop them, he was knocked out.

After he recovered, the Doctor contacted Wilf, who informed him of Naismith and went with him in the TARDIS to the Naismith Manor. In the Manor's basement, the Doctor used his sonic screwdriver to unveil two Vinvocci, Addams and Rossiter, who informed him of the Immortality Gate's true purpose as a medical tool. The Doctor rushed to stop the Gate's activation, but was unable to, and the Master turned the entire human race into copies of himself.

After being taken prisoner, Wilf and the Doctor were rescued by the Vinvocci, who took them to their ship in Earth's orbit, which the Doctor took offline to stop the Master finding them. Realising the Master was planning to rescue the Time Lords from the Time War using a White-Point Star, the Doctor took the gun he initially refused from Wilf and piloted the Vinvocci ship back towards the Naismith Manor, where he crashed through the manor's glass roof. However, he was unable to stop the Master from using the star and the Drumming in his head to create a link to Gallifrey, which allowed Lord President Rassilon and the High Council to escape the time lock on the last day of the Time War.

Rassilon undid the Master's conversion of the human race, as Gallifrey appeared in the Earth's sky and began tearing open the Time Vortex. Torn between killing the Master or Rassilon in cold blood, the Doctor, upon seeing a familiar face, targeted the white-point star, severing the link, condemning the Time Lords to the "hell" of the last day of the Time War. Rassilon tried to kill the Doctor out of spite, but the Doctor was saved by the Master, who attacked Rassilon with his energy blasts in vengeance, which resulted in the Master being sent back into the Time War with the Time Lords.

With the Time Lords and the Master gone, the Doctor was relieved that he had survived his supposed death at Rassilon's hands, but his victory was short-lived when he heard the four knocks. They came from Wilf, who was trapped inside a radiation control booth which was about to be flooded with radiation. The Doctor quickly realised that the only way to save Wilf was to switch places with him, and be subjected to the radiation burst himself. At first angry about the terrible things the universe punished him with and nearly considering Wilf's pleas to leave him, the Doctor could not bear to sacrifice one life to prolong his own after going through so much to stop men willing to take the lives of millions to do the same. Determinant, he released Wilf and received the fatal level of radiation. After the regenerative process started, the Doctor returned Wilf home, and then went to receive, what he called, his "reward". (TV: The End of Time)

Reward
Knowing that this would be his final regeneration, (TV: The Time of the Doctor) the Doctor used his "state of grace" (TV: Twice Upon a Time) to visit all his previous companions and see how they got on after they left the TARDIS, such as watching Jo Grant sail down the Yangtze River in a tea chest. (TV: Death of the Doctor) He saved Martha and Mickey, now working as freelance alien fighters, from a Sontaran, prevented Luke Smith from being run over by a car on Bannerman Road, (TV: The End of Time) visited Hame shortly before her death, (WC: The Secret of Novice Hame) and watched over Heather and Wolfgang, four years after they had left him. (COMIC: Lucky Heather)

The Doctor then travelled to the Zaggit Zagoo bar to pass a note to Jack to hook up with Alonso Frame, and went to a bookstore where Verity Newman, the granddaughter of Joan Redfern, was signing copies of her book, A Journal of Impossible Things. The Doctor had Verity sign his copy while he asked her if Joan had had a happy life. When Verity realised she was talking to the Doctor, she confirmed that Joan had been "happy in the end", but the Doctor refused to answer her question of if he was. (TV: The End of Time)

After years of searching for what became of Carla in the new timeline, the Doctor finally located her. (PROSE: The Haldenmor Fugue) He also encountered Donna's father, Geoff Noble, before the man's death, and borrowed a pound from him. He then went to the future and used that pound to purchase a winning lottery ticket. He witnessed Donna's wedding to Shaun Temple, and asked Sylvia and Wilf to give Donna the triple rollover-winning ticket as a wedding gift, saying a final goodbye to Wilf before he departed. (TV: The End of Time)

With the strain of his impending regeneration beginning to take effect, the Doctor visited George Litefoot on the island of Minos, where he helped him fight the Gentlemen of the Dice. (AUDIO: The Jago & Litefoot Revival)

As he reflected on his companions' lives, the Doctor felt proud of them for using their knowledge and experiences from travelling with him to make their worlds a better place. (TV: Death of the Doctor) To finish his "reward", the Doctor travelled to the Powell Estate on 1 January 2005, where he watched Rose and Jackie walking home from a party. Although he kept to the shadows, a sudden spasm of pain caught Rose's attention and the two exchanged New Year's greetings, with the Doctor telling Rose that she would have a "really great year". (TV: The End of Time)

Death
After Rose left, the pain of regeneration overwhelmed the Doctor, and he collapsed in the middle of the Powell estate, (TV: The End of Time) his "state of grace" having ended. (TV: Twice Upon a Time) Ood Sigma then appeared and told him that the universe would "sing [him] to [his] sleep". Finding the strength to reach the TARDIS, the Doctor piloted it into spatio-temporal orbit around Earth, and regenerated into his next incarnation. Due to holding back his regeneration for as long as he could, the released energy caused massive damage to the TARDIS, causing it to fall out of orbit. (TV: The End of Time)

Post-mortem
After the Eleventh Doctor was accused of committing deadly crimes against the Overcast, he brooded in the TARDIS for two days, imagining all his previous numbered incarnations, including the Tenth Doctor, interrogating him over the crimes. When he offered the rational that he always left things better than he found them, they all turned and left him in disgust and disgrace. (COMIC: Pull to Open)

When the Then and the Now attempted to ingest the Eleventh Doctor's timeline, the Doctor briefly retro-regenerated back into the Tenth and Ninth Doctors. However, the Then and the Now's attack was thwarted by the presence of the War Doctor, due to him being an "X-rated" period of his life that the Doctor resisted. (COMIC: Outrun)

When the Eleventh Doctor was attacked by the Then and the Now on Lujhimene, the Tenth Doctor was among the faces seen as the Doctor's timeline was almost destroyed. (COMIC: Running to Stay Still)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Tenth Doctor, appeared inside it to defend themselves as well. When the Ninth Doctor pointed out how auditor Sondrah was more interested in them than the Earth, the Tenth Doctor agreed with his predecessor, and asked Sondrah if "something inside [him]" had a personnel vendetta with him, only for Sondrah to fearfully warn the Tenth Doctor away from him. Upon seeing Sondrah's reaction to his tenth incarnation, the Eleventh Doctor deduced his true identity, and the past Doctors faded away as Oscar Wilde interfered with the Nexus. (COMIC: Dead Man's Hand)

After saving Gallifrey from the Moment at the conclusion of the Last Great Time War, the Eleventh Doctor dreamed of himself standing with all his past incarnations, including the Tenth Doctor, as he thought about his search for Gallifrey. (TV: The Day of the Doctor)

When he was exposed to energy from a time storm, the Twelfth Doctor degenerated through all of his previous incarnations, including the Tenth Doctor. (AUDIO: The Lost Magic)

Undated events

 * The Tenth Doctor saw the musical Hamilton and had his picture taken by Alice Obiefune when he was near his second and eleventh incarnations. (COMIC: The Long Con)
 * On a Thursday in the summer of 1966, the Tenth Doctor visited Andy Warhol to have his face added to a portrait of eleven incarnations of the Doctor. (PROSE: The War of Art; COMIC: The Girl Who Loved Doctor Who)
 * The Tenth Doctor visited Eirene, and saved them from a horde of Almind. He left a card for the Ninth Doctor, who arrived soon after. (PROSE: A Day to Yourselves)

Donna's World
In a parallel world in which Donna Noble never met him, and wasn't there to convince him to flee after defeating the Empress of the Racnoss, the Doctor drowned when the Thames was drained into the abandoned Torchwood base. For reasons unknown, the Doctor failed to regenerate; Private Harris speculated it had "happened too fast" for the process to start. His body was retrieved by UNIT soldiers and his TARDIS was salvaged from under the Thames, later being sent to a UNIT base in Leeds. (TV: Turn Left)

Confronting the Lost
After losing Mark on Beltos Station, (AUDIO: The Trojan Dalek) the Doctor and Anya’s ship began to malfunction. Having her set a course for the Gruad Confusion, a weak point in space and time, the Doctor used the stolen time engine to attempt a time jump, arrived in the realm home to the Lost. It revealed a portal which could transport only one of them and attempted to emotionally manipulate them into abandoning each other and taking it along with them inside their body, driving a wedge between them by reminding the Doctor of Ann Kelso and other lost companions and exposing his role in Sara Kingdom and Bret Vyon’s deaths to Anya. Eventually Anya decided to force the Doctor to leave and stop the Lost escaping, by pretending to go along with it and then activating a detonator, killing herself and injuring the Lost that had been inside her. The Doctor refused to accept this outcome and used the time engine to jump back to before he and Anya attempted the time jump, guiding him to avoid arriving in the Lost’s realm in the first place. The alternative Doctor died in doing so, however memories of this timeline were retained by the Doctor. (AUDIO: The Lost)

Multi-Doctor event
The Doctor and Gabby became involved in a "Multi-Doctor Event" with the Twelfth Doctor, Clara Oswald, 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)

Time Lord Victorious
In an alternative timeline envisioned by a continuity bomb, instead of sacrificing himself, the Doctor let Wilfred die in the radiation chamber of the Immortality Gate, viewing himself to be "more valuable to the universe", though he regretted his choice and broke down in tears immediately afterwards. The Doctor then went on to embrace the title of "Time Lord Victorious" and became a dictator "whose rule fixed a broken cosmos". He met his end at the hands of a Raxacoricofallapatorian who shot him with a weapon that seemingly cancelled the regenerative process. (COMIC: Four Doctors)

Personality
The Tenth Doctor was cheerful, charismatic, hyperactive and enthusiastic, often at inappropriate times, (TV: Tooth and Claw, The Unicorn and the Wasp, Midnight) but would become severely serious when the situation called for it. (TV: Rise of the Cybermen, The Idiot's Lantern, Doomsday, Silence in the Library, Midnight) Striving to make new friends everywhere he went, (TV: Midnight) the Doctor tended to keep a massive smile on his face as he found new ways to enjoy his unpredictable journeys through time and space, with the thought of a mundane existence unnerving him. (TV: The Impossible Planet, Gridlock)

While he seemed to have resolved much of the survivor's guilt felt previously, the Tenth Doctor had begun to feel his age. (TV: Silence in the Library) Beneath his juvenile exterior was an old man who had seen many terrible things and felt a deep loneliness, (TV: School Reunion, The Lazarus Experiment, The Family of Blood) though he did enjoy the freedoms that came with solitary travels. (TV: Midnight) He felt profound regret for the deaths he had seen, (TV: Journey's End) with the Moment referring to him as "the man who regrets". (TV: The Day of the Doctor) His keen sense of loss led him to empathise with those who had also suffered, (TV: Fear Her) and feel driven to prevent death and destruction wherever possible, having a hard time accepting failure. (TV: Voyage of the Damned) Donna Noble noted the reason the Doctor required a companion was to keep him from succumbing to his darker side. (TV: The Runaway Bride)

Despite being more outwardly cheerful than his previous incarnation, the Doctor still felt guilt over what he had done in the Last Great Time War, showing disgust towards the Eleventh Doctor when he was unable to remember how many children died when he destroyed Gallifrey, despite him knowing the number to memory. (TV: The Day of the Doctor) The Tenth Doctor also retained and even exceeded his predecessor's capacity for righteous anger, particularly when people he liked were threatened or at risk, (TV: New Earth, The Idiot's Lantern, Gridlock, Forest of the Dead) or when dealing with the Daleks. (TV: Evolution of the Daleks, Journey's End) When driven by his anger, he would not hesitate to strike down those who opposed him. (TV: The Christmas Invasion, The Runaway Bride, The Family of Blood) Despite this, the Doctor described himself as "a man who never would" after he chose not to kill General Cobb to avenge Jenny's death. (TV: The Doctor's Daughter)

The Doctor had a merciful and compassionate nature, consistently extending an offer of mercy to help even his most dangerous enemies. (TV: Evolution of the Daleks, The Sound of Drums, The Poison Sky, Forest of the Dead, Journey's End, The Next Doctor) However, when his patience reached its limit or his enemies were duplicitous, they received no mercy or second chances. (TV: The Christmas Invasion, School Reunion, The Runaway Bride, The Family of Blood, Partners in Crime, The Next Doctor) He also held a forgiving philosophy, even forgiving for his crimes against humanity. (TV: Last of the Time Lords)

The Tenth Doctor's main personality flaw was his ego, with him always trying to take control of situations he found himself in, (TV: Army of Ghosts, The Poison Sky, Silence in the Library, Midnight) and feeling it his place to punish those who committed horrific acts. (TV: The Christmas Invasion) Occasionally, he stated himself to be at a higher authority than he actually was, (TV: New Earth, Gridlock, Voyage of the Damned) and believed himself to often be the smartest being in the room. (TV: The Age of Steel, Smith and Jones, Midnight, Planet of the Dead) When introduced to Louis XV, the Doctor introduced himself as the "Lord of Time" in an attempt to outrank the King of France. (TV: The Girl in the Fireplace) He would sometimes use his name as a threat. (TV: New Earth, Forest of the Dead)

He was also something of a hypocrite; calling Colonel Mace undiplomatic for calling the Sontarans "trolls", only to begin antagonising them himself mere seconds afterwards, (TV: The Poison Sky) claiming he would not allow Strackman Lux's pride to cost lives while refusing to sign Lux's contract for the same reason, (TV: Silence in the Library) and being offended when Malcolm Taylor hung up on him, despite him previously doing the same to Malcolm. (TV: Planet of the Dead)

After being forced to wipe Donna Noble's memories of her travels with him, the Doctor was driven into a deep state of depression, (TV: Journey's End) and exiled himself away from the idea of picking up any more companions, (TV: The Next Doctor) even refusing Lady Christina de Souza's request to travel with him, (TV: Planet of the Dead) though he made exceptions with Heather McCrimmon, (COMIC: The Chromosome Connection) Wolfgang Ryter, (COMIC: Flight of the Giurgeax) Gisella, (PROSE: The Depths of Despair) Gabby Gonzalez, (COMIC: The Arts in Space) Majenta Pryce, (COMIC: Thinktwice) Emily Winter, and Matthew Finnegan. (COMIC: Fugitive)

After he was given a prophecy of his demise by a human psychic, the Doctor spiralled further into an emotional breakdown that caused him to snap and try to alter a fixed point in time by saving Adelaide Brooke, Yuri Kerenski and Mia Bennett from the destruction of Bowie Base One. Upon his success, he declared himself as the "Time Lord Victorious" and believed that, as the last Time Lord, he had the right to control the Laws of Time. Following Brooke's suicide, the Doctor realised he had gone too far and entered another state of depression upon knowing his regeneration was fast approaching. (TV: The Waters of Mars) His shock caused him to flee into the Dark Times, where he became determined to completely rewrite history for the better by wiping out the Kotturuh before they could bring death to the universe, deeming himself the "master of [his] own fate, [and] everyone's fate" once the Kotturuh marked him for death. Though he still retained his doubts, he was finally provoked into destroying the Kotturuh after they killed Estinee, (PROSE: The Knight, The Fool and The Dead) and destroyed the planet Mordeela in his anger. (PROSE: All Flesh is Grass) Though he later sought the Minds of Magnox for confirmation he had done the right thing, being frustrated when they refused to answer. (AUDIO: The Minds of Magnox) However, after meeting the last Kotturuh, Inyit, and seeing what the Daleks had done in the Dark Times, he conceded that his actions had been wrong, and expressed his remorse after Inyit died defeating the Daleks. Though satisfied with the change to how death would eventually enter the universe, he agreed he had gone too far in rewriting of history. (PROSE: All Flesh is Grass) When he confronted the Network sometime after leaving the Dark Times, the Doctor claimed he was now trying draw a line under death to find better futures, having realised responding to death with death only made things worse. (AUDIO: Echoes of Extinction)

By the time he had finally decided to go to the Ood Sphere, the Doctor had come to greatly regret his actions as the Time Lord Victorious, weeping when he admitted to Wilf that things had gone wrong, but he still showed some signs of a colder demeanour, such as briefly questioning Wilf's importance when he realised he would have to sacrifice his own life to save him, but ultimately gave his life for Wilf. (TV: The End of Time)

Much like his fourth incarnation, the Tenth Doctor had a great respect and admiration for humanity, as well as a great desire to protect them, often noting their achievements, (TV: The Christmas Invasion, Utopia) describing human beings as both "brilliant" and "stupid" in the same sentence while arguing the necessity of emotions with John Lumic. (TV: The Age of Steel) He also hugged Captain Zachary Cross Flane of the Walker Expedition, due to the human crew daring to explore a planet orbiting a black hole merely "because it was there". (TV: The Impossible Planet) When Wilf said that humanity must "look like insects" to a Time Lord, the Doctor responded that he thought they "look[ed] like giants". (TV: The End of Time) However, he was not blind to their flaws, (TV: The Christmas Invasion, The Age of Steel, Army of Ghosts, 42) and was aware of his tendency to forget that humanity could be "stupid, stubborn and fail to learn from [their] mistakes". (PROSE: Wetworld) He once admitted to Donna that he was uncertain if humanity could be considered mere explorers or like a virus to the galaxy. (TV: Planet of the Ood)

The Doctor had a stated fondness for "little shops", the gift stores usually found in hospitals and other public places, though he retained his eighth incarnation's dislike for hospitals. (TV: New Earth, Smith and Jones, Silence in the Library) By his own admission, he had little interest in sport, (AUDIO: Time Reaver) and took two sugars in his tea, (PROSE: Ghosts of India) with Earl Grey with a dash of milk being his preference. (PROSE: Autonomy) His favourite movie was It's a Wonderful Life, (PROSE: Loose Wire) and he considered edible ball bearings to be a "masterpiece". (TV: Fear Her)

1727 and 1953 were among his favourite years. (TV: The Girl in the Fireplace, The Idiot's Lantern) He liked Saturdays, (TV: The Stolen Earth) but thought that Sundays were boring, and tried to avoid them when he could. (TV: Silence in the Library)

He also liked the impossible, (TV: New Earth) The Muppet Movie, (TV: Tooth and Claw) bananas, (TV: The Girl in the Fireplace) picnics, picnic baskets, (PROSE: Sting of the Zygons) fire engines, (PROSE: The Last Dodo) the pyramids, New Zealand, (TV:Voyage of the Damned) unpredictability, (TV: The Fires of Pompeii) mysteries, (TV: The Doctor's Daughter) biographies, (TV: Silence in the Library) the Proms, (TV: Music of the Spheres) snow, (TV: The Waters of Mars) teachers, (COMIC: Four Doctors) rock and roll music, (PROSE: Loose Wire) theatre, and fan fiction. (PROSE: He's Behind You)

He disliked Margaret Thatcher, (TV: Tooth and Claw) calling a group a "team", (TV: School Reunion) having to start afresh with a new companion, (TV: The Shakespeare Code) zoos, (PROSE: The Last Dodo) spinach, (PROSE: Martha in the Mirror) people saluting him, (TV: The Sontaran Stratagem) pears, (PROSE: The Taking of Chelsea 426) lists, "funny robots", (TV: The Waters of Mars) and thrash metal music. (PROSE: Loose Wire) He did not identify himself as a "cat person". (TV: Fear Her)

While he was unsure about his religious beliefs, the Doctor stated he kept travelling in order to be proved wrong. (TV: The Satan Pit) He viewed life as being "meaningless" if it was built on the suffering of others, (TV: New Earth) and that people made life worth living. (TV: The Age of Steel) He also thought books to be the "best weapons in the world". (TV: Tooth and Claw)

When asked his thoughts on the dead returning as ghosts, the Doctor called the scenario "horrific", (TV: Army of Ghosts) and was likewise unnerved by the idea of humans achieving immortality, (TV: The Lazarus Experiment) describing the fact that Jack Harkness was a living fixed point in time as being "wrong". (TV: Utopia) He believed that a long life led to being tired of everything and ending up alone, (TV: The Lazarus Experiment) and that death gave life "size", with the absence of death in fiction leaving only comedies. (TV: Silence in the Library)

While he knew "crossing into established events [was] strictly forbidden", he would use his TARDIS to perform "cheap tricks." (TV: Smith and Jones) He tried to avoid fixed points in time when he could, as he knew they were not to be disturbed, (TV: The Fires of Pompeii) though briefly thought he could change one when he came to the conclusion that the Laws of Time were his to govern as the last of the Time Lords. (TV: The Waters of Mars)

The Tenth Doctor always attempted to solve a situation without violence, (TV: The Sound of Drums, The Doctor's Daughter, Dreamland, The End of Time) which strained his working relationship with UNIT, with him being against their military methods. (TV: The Sontaran Stratagem, The Poison Sky) He also disapproved of his friends using violence, (TV: The Christmas Invasion, Utopia, The Doctor's Daughter, The Unicorn and the Wasp, Journey's End, The Next Doctor) and would make himself an enemy of those who would kill without proper cause. (TV: The Age of Steel, The Doctor's Daughter, Midnight) However, he would resort to lethal means of despatching his enemies if no alternative could be found. (TV: School Reunion, The Age of Steel, Love & Monsters, The Runaway Bride, Smith and Jones, The Next Doctor)

The Doctor refused to take up a weapon against an enemy, believing it cowardly to do so. (PROSE: Made of Steel) While previous incarnations had, the Tenth Doctor would not, repeatedly refusing even when offered one by UNIT while attacking the Sontarans. (TV: The Poison Sky) However, during a battle with the Cybermen, the Doctor helped Major Burton handle a rocket launcher and destroyed a Cyberman with the weapon, despite hesitating due to it previously being human. (PROSE: Made of Steel) He was also tempted to execute General Cobb for the murder of Jenny, but ultimately decided against it. (TV: The Doctor's Daughter) During the Kotturuh crisis, the Doctor very reluctantly accepted control of the Victis Fleet after Brian made him its admiral to fight the Kotturuh. (PROSE: The Knight, The Fool and the Dead) After initially refusing several times to take up Wilfred Mott's pistol to save himself and humanity from, the Doctor changed his mind when he heard that the Time Lords were returning. (TV: The End of Time) Davros noted his refusal to take up a gun, but pointed out that he "[took] ordinary people and [fashioned] them into weapons". (TV: Journey's End) When Clara Oswald insisted the war, tenth and eleventh incarnations find a different way to end the Time War, the Tenth Doctor embraced the chance to do so when a plan was formed and worked with twelve of his other incarnations to save his planet and people. He was upset when he realised he wouldn't be able to remember what they had achieved, but was still happy with the outcome. (TV: The Day of the Doctor)

He knew when it was time to focus on the task at hand instead of trying to save someone, and would encourage others to mourn only when they were out of danger, (TV: The Age of Steel, Army of Ghosts, Voyage of the Damned) as well as focus on the "big picture" instead of focusing on minor problems. (TV: The Runaway Bride) He likewise had little patience for those who tried to deny the situation around them, (TV: Smith and Jones) and those who would bully those weaker than them. (TV: Voyage of the Damned)

While previous incarnations intentionally flouted social conventions, the Tenth Doctor was genuinely shocked when he realised that he was being rude or uncouth. (TV: The Christmas Invasion, Tooth and Claw, Fear Her, Utopia) According to the Eleventh Doctor, the Tenth Doctor had vanity issues. (TV: The Time of the Doctor)

The Tenth Doctor engaged in romantic situations far more frequently than his other incarnations, (TV: The Day of the Doctor) falling in love with Rose Tyler. However, he found himself unable to explicitly describe these feelings, struggling with saying such things aloud. (TV: School Reunion, The Satan Pit, Doomsday) In the end, it was the Meta-Crisis Tenth Doctor that revealed the Doctor's feelings for her. (TV: Journey's End) He also developed a romantic relationship with Madame de Pompadour. (TV: The Girl in the Fireplace) Others who wanted to engage him romantically included Martha Jones, (TV: Human Nature, Last of the Time Lords) Jack Harkness, (TV: The Sound of Drums) Astrid Peth, (TV: Voyage of the Damned) Clare Pope, (TV: Partners in Crime) River Song, (TV: Silence in the Library) Christina de Souza, (TV: Planet of the Dead) Minnie Hooper, (TV: The End of Time) and Elizabeth I. (TV: The Day of the Doctor) Joan Redfern became romantically involved with his human identity, but viewed the Doctor himself as merely a look-a-like of him. (TV: The Family of Blood)

The Tenth Doctor was particularly fond of his fifth incarnation. After meeting him, he was delighted, though he gently mocked the Fifth Doctor for wearing celery. However, the Tenth Doctor expressed that he enjoyed his fifth incarnation enough to take certain traits from him, such as wearing glasses to look clever, converse shoes and the way his voice went squeaky with excitement. (TV: Time Crash) He also considered the Third Doctor to be "brilliant". (COMIC: The Lost Dimension)

Initially, he was fearful of his war incarnation, but soon grew to greatly respect him for the impossible choices he had to make during the Time War. He admitted that it was as "an honour and a privilege" to work alongside him, and his eleventh incarnation, to save Gallifrey. (TV: The Day of the Doctor) The Tenth Doctor held a rather low opinion of his previous incarnation, considering him to be violent due to being "born in battle". (TV: Journey's End) Nonetheless, he mused along with his twelfth incarnation that the Ninth Doctor was nothing short of "fantastic". (COMIC: Four Doctors) During the Kotturuh crisis, he was very critical of the alliances the Eighth and Ninth Doctors had made with Daleks and Vampires and resisted their attempts to stop his campaign, viewing their interference as unfair. He reconciled with them after collaborating to save Gallifrey and came to accept they'd been right to try to stop him. (PROSE: All Flesh is Grass) The Tenth Doctor later showed pity for the Eighth Doctor after hearing his transmission on Orriv, reflecting that he was about to be put through hell trying to rectify his future self's mistake and then thrust into the Time War and wishing he could tell his younger incarnation this. (AUDIO: Echoes of Extinction)

When it came to his future incarnations, the Tenth Doctor was often suspicious of them, (TV: The Day of the Doctor) in part because of his meeting with Jackson Lake. (COMIC: Four Doctors) He would often seek conformation of their identities by comparing sonic screwdrivers, (TV: The Day of the Doctor) or would scan them with the screwdriver himself. (COMIC: Four Doctors) Despite a rocky start, he worked well with the Eleventh Doctor, although did get somewhat irritated by his childish side and was disgusted by his attitude towards those who had died in the Time War. (TV: The Day of the Doctor)

Because he thought he couldn't exist due to their limited number of regenerations left, the Tenth Doctor was very cold and argumentative with the Twelfth Doctor, even calling him an "abomination" and briefly accused him of being the Valeyard, though they were able to work together with their companions and the Eleventh Doctor acting as mediators. (COMIC: Four Doctors) When the Tenth Doctor met his twelfth incarnation at St Luke's University, he was more open to the idea of him, even calling him "brilliant" upon discovering his identity, though he lamented how elderly the Twelfth Doctor appeared. (COMIC: The Lost Dimension)

The Ninth Doctor thought his tenth incarnation was "fantastic" for how much he had changed since the Time War. The Tenth Doctor was met with similar affections by his second and fifth incarnations, while the First Doctor referred to him as "infantile" and the Third Doctor dismissed his intelligence. (COMIC: The Forgotten)

The Tenth Doctor enjoyed teasing his friends, (TV: School Reunion, Rise of the Cybermen, The Runaway Bride) and was not above being sarcastic to them. (TV: The Christmas Invasion, Smith and Jones, The Shakespeare Code) He continued his previous incarnation's habit of teasing and making fun of Jackie Tyler, though generally in a more playful fashion. (TV: Children in Need Special, The Christmas Invasion, Tooth and Claw, The Idiot's Lantern, Army of Ghosts) He also had a noticeably more positive relationship with Mickey Smith than his predecessor, treating him as more of an equal and friend, (TV: The Christmas Invasion, Age of Steel, Doomsday) though he occasionally relapsed into making fun of him or being dismissive. (TV: School Reunion, The Girl in the Fireplace, Rise of the Cybermen) The Doctor also prodded at Jack Harkness after they reunited, resuming his habit of telling Jack to "stop it" whenever he said hello to someone, which he saw as Jack's way of flirting with them. (TV: Utopia) The Doctor referred to Donna Noble as his best friend, and had a great respect for her grandfather, Wilfred Mott, thinking of him as a kindred spirit, as he was also aged and experienced, yet energetic and unwilling to commit violence against others. The Doctor also stated that he felt it an honour to know Wilf, and claimed he would have been proud if he was his father. (TV: The End of Time)

While he acknowledged that "children can be cruel", (PROSE: The Mystery of the Haunted Cottage) the Tenth Doctor showed parental compassion towards the children he encountered, engaging in friendly conversations with a young Reinette and protecting her from a Clockwork Droid, (TV: The Girl in the Fireplace) giving Tim Latimer his fob watch as a memento of their adventure together, (TV: The Family of Blood) and complimenting the Bannerman Road gang when they did tasks well and came up with good ideas while they were under his care during his encounter with the Trickster. (TV: The Wedding of Sarah Jane Smith) While the Doctor showed little remorse in having to kill the Racnoss Empress' children to save the human race, (TV: The Runaway Bride) he showed compassion towards the young Adipose, deeming them innocent to the crimes of their parents. (TV: Partners in Crime)

The Tenth Doctor retained the hatred for the Daleks displayed in previous incarnations, (TV: Daleks in Manhattan) believing them incapable of changing their minds about killing all life that was unlike them. (TV: Evolution of the Daleks) However, his approach to them was to be dismissive rather than out right angry, (TV: Doomsday, Evolution of the Daleks, Journey's End) playfully denying the Cult of Skaro's requests to open the Genesis Ark and mocking their retreat into the Void Ship to escape the Time War as "cowardly". Regardless, he still considered them a greater threat to humanity than the Cybermen and reluctantly admired their attempts to think "above and beyond the Emperor himself". (TV: Doomsday) In particular, he grew to admire Dalek Sec when he became a Dalek-Human hybrid, going as far as to call him "the cleverest Dalek ever" after he tried to find redemption for the Daleks. He also attempted to empathise with Dalek Caan after he committed genocide against the Dalek-Human hybrid race, daring to offer his help towards Caan, citing how they were both the last of their respective people. (TV: Evolution of the Daleks) During the Kotturuh crisis, he was furious at the Eighth Doctor's initial alliance with them and confessed to Brian it was becoming hard to act dismissive in front of the Daleks, as he really wanted to just scream at them. (PROSE: All Flesh is Grass) His preference to ignore and spite Daleks stretched to their creator, Davros, whom he insulted for his persistence to keep on creating Daleks even after their betrayals of him, (TV: The Stolen Earth) and how he had become the Daleks' "pet" after the formation of the New Dalek Empire. However, he offered to save Davros from the Cruciform after the Meta-Crisis Tenth Doctor began its destruction, only for Davros to refuse his aid. (TV: Journey's End)

The Doctor scorned the Cybus Industries Cybermen, notably their creator, John Lumic, for removing imagination and emotions from humanity, believing that he removed the reason for living at all. (TV: The Age of Steel) He also dismissed the Sontarans' threat as dishonourable, mocking General Staal for avoiding combat in favour of using clone feed. (TV: The Poison Sky)

The Tenth Doctor expressed pity for, (TV: Last of the Time Lords) wanting to convince him that they could live together and "see" the universe rather than "own" it, going as far as to offer to help cure the Master's insanity. (TV: The End of Time) He also pledged to support the Master in his goals to conquer the universe in return for leaving Earth alone, but the Master refused. (TV: The Sound of Drums)

Tim Latimer described the Tenth Doctor as "like fire and ice and rage, [that he was] like the night and the storm in the heart of the sun, [as well as being] ancient and forever, [burning] at the centre of time, and [could] see the turn of the universe." Despite his horrifying description, Latimer considered the Doctor to be "wonderful," (TV: The Family of Blood) a sentiment that Wilfred Mott also expressed. (TV: The End of Time) While Valerie Brannigan dismissed him as "insane", Thomas Kincade Brannigan commented that the Doctor was "that, and a bit magnificent." (TV: Gridlock) Donna Noble described him as "dazzling". (TV: The Sontaran Stratagem) Clara Oswald, when distinguishing him from his other incarnations, described the Tenth Doctor as "the hero", (TV: The Day of the Doctor) while Adam Mitchell identified the Tenth Doctor as the "Oncoming Storm" in comparison to his other incarnations. (COMIC: Unnatural Selection) Rose viewed him as being more carefree than his ninth incarnation, (PROSE: He's Behind You) while Jack believed him to be more "cheeky". (TV: Utopia) The TARDIS believed he was "afraid of Death". (PROSE: What the TARDIS thought of "Time Lord Victorious") Whilst he was the Time Lord Victorious, Brian believed the Tenth Doctor "was vengeance" and, as a result, the assassin much preferred him to the Eighth Doctor. (PROSE: All Flesh is Grass)

Having experienced a similar process as John Smith, (TV: The Family of Blood) the Doctor became fearful of his inevitable regeneration, going so far as to prevent the process by channelling the excess energy of his regeneration into his severed hand after being shot by a Dalek. (TV: Journey's End) He commented that regeneration was not a rebirth, but the death of himself. (TV: The End of Time) When Carmen prophesied his "song ending", the Doctor reacted with stunned silence, (TV: Planet of the Dead) and later became emotionally distressed when Ood Sigma heralded his demise. (TV: The Waters of Mars) When death seemed a certainty, the Doctor chose to think of the children killed on Gallifrey when he destroyed it as his last thoughts. (PROSE: The Day of the Doctor)

When he realised he would have to sacrifice his life to save Wilfred Mott from the radiation of the Immortality Gate after thwarting Rassilon's Ultimate Sanction, the Doctor at first had a tantrum about how his "reward" was "not fair" and was tempted to let Wilf die when he requested it, but ultimately decided to fulfil Carmen's prophecy and save Wilf. (TV: The End of Time) While he put on a brave face for Rose, Jack and Donna during his aborted regeneration, (TV: The Stolen Earth) when his time finally came, the Doctor instead stated his reluctance to "go", and regenerated with tears in his eyes, afraid and alone. (TV: The End of Time)

Habits and quirks
The Tenth Doctor spoke in an accent described by George Litefoot as "a kind of cultured cockney, flecked with hints of Scots", (AUDIO: The Jago & Litefoot Revival) that the Eleventh Doctor compared to the voice of Dick van Dyke. (TV: The Day of the Doctor) Mickey Smith thought that the Doctor might have picked it up from Rose. (PROSE: The Christmas Invasion) Indeed, the Doctor himself once mentioned that he picked up his accent from the Powell Estate. (COMIC: Silver Scream) His voice tended to peak in high tones when expressing excitement, (TV: The Christmas Invasion, New Earth, 42, Time Crash, Planet of the Ood)

The Tenth Doctor was fond of the French word, "Allons-y!", (TV: Army of Ghosts, Evolution of the Daleks, 42, Voyage of the Damned, The Fires of Pompeii, Midnight, The Next Doctor, Planet of the Dead, The Wedding of Sarah Jane Smith, Dreamland, The End of Time, The Day of the Doctor) describing it to Addams as a word of "consolation to the soul in times of need". (TV: The End of Time) Other favoured phrases of his were "blimey", (TV: The Christmas Invasion, Fear Her, The Runaway Bride, Evolution of the Daleks, 42, Utopia, Voyage of the Damned, The Fires of Pompeii, Journey's End, The Waters of Mars, The End of Time) and "Molto bene". (TV: The Runaway Bride, The Family of Blood, Planet of the Ood, Midnight, The Waters of Mars)

While attempting to explain something, he would often interrupt himself with a, "well...", and further elaborate what it was he was talking about. (TV: The Christmas Invasion, Tooth and Claw, The Girl in the Fireplace, The Age of Steel, Army of Ghosts, The Runaway Bride, Smith and Jones, Blink, Utopia, The Sound of Drums, Time Crash, Voyage of the Damned, Partners in Crime, The Fires of Pompeii, The Poison Sky, The Doctor's Daughter, The Unicorn and the Wasp, Forest of the Dead, Journey's End)

The Doctor often remarked that exotic technology or life was "beautiful" or "brilliant" and was genuinely enthralled by such discoveries, sometimes to the extent that he placed himself, his companions and bystanders in danger. (TV: Tooth and Claw) Like his seventh incarnation, he would insist he was "always all right", even when all evidence pointed to the contrary. (TV: The Girl in the Fireplace, Forest of the Dead) An apologetic incarnation, the Tenth Doctor also made use of the phrase, "I'm sorry, I'm so sorry". (TV: New Earth, The Age of Steel, The Impossible Planet, Army of Ghosts, The Poison Sky, Silence in the Library)

Another favoured exclamation of his was, "Oh, yes!", which he would say in moments of gleeful realisation, (TV: The Satan Pit, Doomsday, The Shakespeare Code, The Infinite Quest, The Sound of Drums, Voyage of the Damned, Partners in Crime, Planet of the Ood, Planet of the Dead, The End of Time) when angered or disturbed greatly, (TV: Evolution of the Daleks, The End of Time) or simply as a response to something. (TV: The Age of Steel, Smith and Jones, Evolution of the Daleks, Utopia, Time Crash, Voyage of the Damned, Partners in Crime, The Fires of Pompeii, The Doctor's Daughter)

When he was faced with an occurrence that dumbfounded him, the Doctor would repeatedly say, "What?", looking increasingly astonished with each repetition. (TV: Doomsday, The Shakespeare Code, Last of the Time Lords, Time Crash, The Poison Sky, Music of the Spheres) He would also dismiss things with a loud exclamation of, "Nah." (TV: The Girl in the Fireplace, The Idiot's Lantern, Army of Ghosts, Gridlock, The Poison Sky, Silence in the Library, Midnight, Music of the Spheres, The Waters of Mars)

When he discovered something that disagreed with his knowledge, he would usually utter, "it can't be", (TV: School Reunion, The Impossible Planet, The Runaway Bride, Utopia, The Sound of Drums, The Stolen Earth) and would frequently describe something that dumbfounded him as "impossible". (TV: New Earth, Rise of the Cybermen, The Impossible Planet, The Satan Pit, Army of Ghosts, Doomsday, The Runaway Bride, The Stolen Earth) Like his previous incarnation, the Doctor occasionally used "hell" as an intensive. (TV: Tooth and Claw, The Age of Steel, The Idiot's Lantern, Fear Her, Army of Ghosts, The Runaway Bride, Smith and Jones, Partners in Crime, The Fires of Pompeii, The Next Doctor)

Typically, he would lean against a surface with his legs stretched out and crossed together, with his arms sometimes folded together, (TV: Partners in Crime, The Next Doctor, The Waters of Mars) but he mostly kept his hands in his pockets when in this position. (TV: The Impossible Planet, Love & Monsters, Smith and Jones, Time Crash, The Doctor's Daughter, The Unicorn and the Wasp, The Wedding of Sarah Jane Smith) Indeed, it was extremely rare for the Tenth Doctor to go a whole adventure without once putting his hands in his pockets. (TV: The Satan Pit, Smith and Jones, Blink, Time Crash, The Poison Sky, Midnight, Dreamland) He often sat with his feet up and legs stretched out and crossed. (TV: Army of Ghosts, Last of the Time Lords, The Poison Sky, The Day of the Doctor)

He would sometimes pull at his jaw when thinking, (TV:  Fear Her, Army of Ghosts, Smith and Jones, Evolution of the Daleks, Utopia, The Sound of Drums, Last of the Time Lords, Voyage of the Damned, The Waters of Mars, The Day of the Doctor) and often held his arms behind his back, (TV: The Christmas Invasion, Tooth and Claw, The Idiot's Lantern, The Satan Pit, Fear Her, Army of Ghosts, The Runaway Bride, Smith and Jones, The Family of Blood, The Sound of Drums, Last of the Time Lords, Time Crash, Voyage of the Damned, The Fires of Pompeii, The Sontaran Stratagem, The Doctor's Daughter, The Unicorn and the Wasp, The Next Doctor, Planet of the Dead, The Waters of Mars, Dreamland) or casually had his arms folded. (TV: Children in Need Special, School Reunion, Rise of the Cybermen, The Age of Steel, The Idiot's Lantern, Fear Her, Doomsday, Smith and Jones, The Infinite Quest, The Shakespeare Code, Evolution of the Daleks, The Lazarus Experiment, 42, The Sound of Drums, Last of the Time Lords, The Fires of Pompeii, Planet of the Ood, The Sontaran Stratagem, Silence in the Library, The Waters of Mars, The End of Time, The Day of the Doctor)

The Doctor would scratch the back of his head when thinking, (TV: New Earth, Tooth and Claw, The Impossible Planet, Army of Ghosts, Doomsday, The Runaway Bride, Smith and Jones, Gridlock, Human Nature, Voyage of the Damned, Partners in Crime, Forest of the Dead, Midnight, The Stolen Earth) embarrassed, (TV: The Age of Steel, The Runaway Bride, The Sontaran Stratagem, Silence in the Library) or when reluctantly admitting fault. (TV: The Poison Sky) He was also known to run his hands through his hair when feeling intense. (TV: New Earth, Tooth and Claw, Smith and Jones, Evolution of the Daleks, The Sound of Drums, The Poison Sky, The Stolen Earth, The Waters of Mars, The Day of the Doctor)

He also made a habit of scratching around his left ear, (TV: New Earth, The Girl in the Fireplace, The Idiot's Lantern, The Impossible Planet, Love & Monsters, Army of Ghosts, The Shakespeare Code, Daleks in Manhattan, Evolution of the Daleks, The Lazarus Experiment, Utopia, The Sound of Drums, Voyage of the Damned, Partners in Crime, The Fires of Pompeii, The Next Doctor, Music of the Spheres, Planet of the Dead) crouching down with his elbows rested on his knees, (TV: New Earth, The Girl in the Fireplace, Rise of the Cybermen, Fear Her, Army of Ghosts, Smith and Jones, Gridlock, Daleks in Manhattan, Evolution of the Daleks, The Lazarus Experiment, Silence in the Library, Midnight, Dreamland, The Day of the Doctor) and raising his left eyebrow. (TV: Smith and Jones, Gridlock, Daleks in Manhattan, The Infinite Quest, Voyage of the Damned, Partners in Crime, The Wedding of Sarah Jane Smith, The Waters of Mars)

He would stare longingly with a look of despair when depressed, (TV: The Girl in the Fireplace, Doomsday, The Runaway Bride, Voyage of the Damned, The Doctor's Daughter, Forest of the Dead, Journey's End, The End of Time) or in deep thought. (TV: 42, The Unicorn and the Wasp, Midnight, The Stolen Earth, Planet of the Dead, The Waters of Mars, The End of Time)

The Doctor was an aficionado of twentieth century culture and made frequent references to movies, shows, books and songs from that era, (TV: The Christmas Invasion, The Idiot's Lantern, Army of Ghosts, The Shakespeare Code, 42) though did not understand certain remarks, such as being called a "science geek". (TV: The Lazarus Experiment) He was also fond of rock-and-roll, attempting to take Rose to see concerts by both Ian Dury and Elvis Presley. (TV: Tooth and Claw, The Idiot's Lantern)

The Tenth Doctor was a foodie, often taking the time to snack on food and drink during his adventures. (TV: School Reunion, The Girl in the Fireplace, The Idiot's Lantern, Fear Her, The Lazarus Experiment, The Unicorn and the Wasp, Midnight, Turn Left, The Day of the Doctor) He often talked about favourite foods and recipes, and wasn't afraid to try something new, such as seaweed truffles. (PROSE: Martha in the Mirror)

He would cup his face while sitting, jump over obstacles in his path, and give of a serious of quick, "no"s, when displeased.

The Doctor relied heavily upon his sonic screwdriver, pushing it to limits not seen in previous incarnations, (TV: Smith and Jones) and even chiding the Fifth Doctor for going "hands free". (TV: Time Crash) He felt defensive of his sonic screwdriver, debunking Dalek Sec's initial claim that it was a sonic probe in a hurt manner, (TV: Doomsday) going as far as to say he "loved" it. (TV: Smith and Jones)

The Doctor also revived the occasional use of a stethoscope in mostly non-medical situations, such as the diagnosis of electronic or mechanical faults or to eavesdrop on others, (TV: Rise of the Cybermen, The Idiot's Lantern, The Runaway Bride, Daleks in Manhattan, Partners in Crime, Midnight, The Stolen Earth) though he did occasionally use it to help with medical needs, (TV: Evolution of the Daleks, Planet of the Ood, The Doctor's Daughter, The Next Doctor) He used a hammer many times to help him pilot the TARDIS. (TV: Tooth and Claw, The Runaway Bride, Partners in Crime, The Sontaran Stratagem)

Skills
Having an "honest face", (TV: Planet of the Dead) the Tenth Doctor had a talent for earning people's trust, even despite initial animosity, (TV: The Age of Steel, The Impossible Planet, Dreamland) being able to convince complete strangers to reveal secretive information to him, (TV: Rise of the Cybermen, The Age of Steel, The Idiot's Lantern, The Next Doctor) due to recognising that confused people were more likely to reveal useful information and deliberately keeping them off-balance. (PROSE: The Price of Paradise) Some would even come to his defence when others thought he was a threat or a nuisance to the public. (TV: Voyage of the Damned, The Unicorn and the Wasp, Midnight)

Like his previous incarnation, he had a gift for exerting authority, (TV: New Earth, Tooth and Claw, The Age of Steel, The Satan Pit, 42, Silence in the Library) with even the most resistant of individuals eventually submitting to his way of thinking, (TV: The Idiot's Lantern, Army of Ghosts, Voyage of the Damned, The Poison Sky) However, when struggling to solve the issue at hand, people would dismiss his perceived authority as egotistical and they would actively turn against him. (TV: Midnight) Adelaide Brooke went so far as to kill herself in defiance to the Doctor's self-declared status as the "Time Lord Victorious", despite him initially convincing her to trust him. (TV: The Waters of Mars)

Like his previous incarnations, the Tenth Doctor was exceptionally intelligent, being able to figure out solutions to problems even when they were created by an equally intelligent opponent, (TV: School Reunion, Smith and Jones, The Sound of Drums) but mostly improvised his strategies, using the justification that he did so "brilliantly". (TV: The Age of Steel) He often did mathematical calculations in his head very quickly, making estimates and waiting for those around him to respond, and then giving a very exact answer. (TV: Tooth and Claw, Doomsday) He could recount his steps accurately from memory alone, (TV: Dreamland) and even worked out the force that the pull on Krop Tor needed to resist the pull of a black hole in minutes, something that took the entire crew on the base years to figure out. (TV: The Impossible Planet)

The Tenth Doctor was an exceptionally skilled detective, deducing when people had been possessed or replaced, (TV: New Earth, Army of Ghosts, The Poison Sky, Forest of the Dead) picking up on clues that escaped others perception, (TV: The Girl in the Fireplace, The Idiot's Lantern, Fear Her, Daleks in Manhattan, The Unicorn and the Wasp) figuring out how to defeat his opponents from little details they gave away or from his surroundings, (TV: The Age of Steel, The Shakespeare Code) and learning the details of a person after getting a brief glimpse at them. (TV: The Idiot's Lantern, Voyage of the Damned, The Next Doctor) His observation skills proved superior to, noticing that one of his guards was a little too tall to be an exact copy of him. (TV: The End of Time) Although he could be incorrect on occasion, such as when he continuously thought Queen Elizabeth was a Zygon. (TV: The Day of the Doctor)

With his height and build, the Tenth Doctor was extremely nimble and quick on his feet, keeping ahead of significantly faster opponents with ease. (TV: Tooth and Claw, The Lazarus Experiment) He could even outrun and dodge a crane. (TV: Planet of the Ood) Despite his nimble stature, the Doctor was very strong, managing to easily yank the Sycorax leader's electric whip from his grip and snap it in half, (TV: The Christmas Invasion) free Morvin Van Hoff from the grip of a damaged Heavenly Host, (TV: Voyage of the Damned) rip off Lucius Petrus Dextrus' stone arm, (TV: The Fires of Pompeii) hold off a Cyberman with a sword, (TV: The Next Doctor) and lift a grown woman and throw her away from danger in such a way that she landed on her feet. (COMIC: The Arts in Space) He could even hold his own weight and manoeuvre across a beam with just his hands gripping to it. (TV: Forest of the Dead) However, he could be knocked down from a direct blow to the head, (TV: The Idiot's Lantern, Forest of the Dead, The End of Time) and was unable to escape from the hold of artificial opponents without aid. (TV: Smith and Jones, Voyage of the Damned)

The Doctor displayed incredible resilience and resistance to physical pain, (TV: The Christmas Invasion, The Idiot's Lantern, Evolution of the Daleks, 42) quickly recovering from being knocked unconscious and being able to carry on with the matter at hand with no sign of concussion, (TV: The Idiot's Lantern, The Satan Pit, Evolution of the Daleks, Forest of the Dead) and speedily recovered from being stabbed in his left heart, although he needed Martha to strike his back a few times before he could move properly again. (TV: The Shakespeare Code) He also withstood several electrical attacks from, was able to get to his feet with only some difficulty after jumping out of a ship and falling through a skylight, and was able to absorb 500 thousand rads of nuclear energy and survive as well, although it was the final straw for his body and triggered his regeneration, but he refused to allow the pain of the regeneration to overwhelm him until he was back in the TARDIS after visiting his old companions. (TV: The End of Time)

Although he disliked firearms, (TV: The Poison Sky) the Doctor was an extremely good shot with a gun, being able to shoot a White-Point Star from a distance, (TV: The End of Time) as well as throw and catch objects with pinpoint accuracy. (TV: The Christmas Invasion, The Age of Steel, The Family of Blood, Utopia, Partners in Crime, The Sontaran Stratagem, The Unicorn and the Wasp) He was also skilled with a sword, (TV: The Christmas Invasion, The Next Doctor) choosing it as his weapon of choice if he had to fight. (TV: The Unicorn and the Wasp; PROSE: The Mystery of the Haunted Cottage)

The Tenth Doctor was also a skilled telepath, (TV: The Girl in the Fireplace, Fear Her, The Shakespeare Code, Planet of the Ood) being able to wipe Donna Noble's memories, (TV: Journey's End) and hide his true name from those who could read minds. (TV: The Shakespeare Code) During the Year That Never Was, the Doctor also managed to tune himself into the Archangel Network in his plan to defeat. (TV: Last of the Time Lords) He could also hypnotise people with a Venusian Lullaby. (PROSE: Peacemaker)

The Tenth Doctor was skilled at mechanics, being able to construct a variant of gadgets and devices from scrap and other items he had on hand, (TV: The Idiot's Lantern, Army of Ghosts, Daleks in Manhattan, Blink, The Sound of Drums, The Poison Sky, The Day of the Doctor) and also claimed to be "brilliant" with computers. (TV: Gridlock) He was even able to build K9 Mark IV to replace the Mark III after he was destroyed. (TV: School Reunion)

Having once affirmed he could perform medical procedures himself, the Tenth Doctor was a skilled medic, managing to cure the patients of their diseases on New Earth, (TV: New Earth) and also performed surgery on Laszlo, ensuring he lived a long life as a Pig slave. (TV: Daleks in Manhattan) He also briefly sustained the Face of Boe's life to ensure he saw the humans freed from the motorway. (TV: Gridlock) He even used his knowledge to accurately diagnose a man had drowned artificially. (TV: The Shakespeare Code)

He also possessed a heightened sense of smell, which he used to tell which time period he was in by smelling the air, (TV: The Unicorn and the Wasp) and track down the Master. (TV: The End of Time) He could determine the properties of an object by taste, (TV: The Christmas Invasion, Tooth and Claw, The Idiot's Lantern, The Fires of Pompeii, The Unicorn and the Wasp, Planet of the Dead) and was said to have acute hearing. (PROSE: In the Blood)

He was a skilled organist. (TV: The Lazarus Experiment)

The Doctor could pilot the TARDIS like a standard spaceship rather than simply dematerialising it on several occasions. (TV: The Satan Pit, The Runaway Bride, Partners in Crime, The Stolen Earth) He was also able to lock the coordinates of the TARDIS with his sonic screwdriver so that it could only travel between two places in time and space. (TV: Utopia, The Sound of Drums) When told by River Song that he would one day be able to command the TARDIS door to open with a snap of his fingers, he found that he did possess such abilities, after initially believing it to be nonsense. (TV: Forest of the Dead)

He was a skilled pilot, able to take control and navigate a spacecraft through and out of danger. (TV: Voyage of the Damned, Dreamland, The End of Time) He could also ride a horse, (TV: The Girl in the Fireplace, The Day of the Doctor) drive a moped, (TV: The Idiot's Lantern) and fly a hot air balloon. (TV: The Next Doctor)

Having learned "millions of languages", (PROSE: The Eyeless) the Doctor could speak the Pawnee tribal language, (PROSE: Peacemaker) and Ancient North Martian, (TV: The Waters of Mars) as well as the language of the Tritovore. (TV: Planet of the Dead) However, he had never learned Welsh, believing that he would never have the need to use it. (PROSE: The Eyeless)

He could disguise his scent so that he smelt like a human instead of a Time Lord, (TV: The Family of Blood) speed read a book, (PROSE: The Price of Paradise) and use escapology to pinpoint a weak point in his restraints and find the best place to stain against to enable his liberation. (TV: Dreamland) He appeared to have the ability to carry a large and diverse number of objects in his pockets, (TV: Planet of the Dead, The Day of the Doctor) telling Donna Noble that they were "bigger on the inside". (TV: The Runaway Bride)

The Doctor was able to channel radiation through a body part into his own clothing, although the radiated body part was described by him as being "itchy". (TV: Smith and Jones) However, he could only do this with a small amount of radiation and the radiation he absorbed to save Wilfred Mott was too much for him and he was forced to regenerate. (TV: The End of Time) If poisoned, he could also "stimulate the inhibited enzymes [of cyanide] into reversal" by ingesting ginger beer, a form of protein, salt, and receiving a shock. (TV: The Unicorn and the Wasp)

The Doctor also showed an impressive amount of control over his regenerative abilities, more so than his previous incarnations. He was able to heal himself after being shot by a Dalek and then stop himself from changing his form by channelling the regeneration energy into his severed hand. (TV: Journey's End) Improving on the control the First Doctor exhibited, (TV: Twice Upon a Time) the Tenth Doctor was also able to resist regenerating long enough to visit his old friends, though this resulted in his regeneration becoming so violent that the TARDIS was set ablaze in the process. (TV: The End of Time)

Appearance
The Tenth Doctor was a handsome man with a tall, slim frame, finely boned hands and face, thick brown hair, pale skin scattered with freckles, and large, dark brown eyes, (TV: The Parting of the Ways, Children in Need Special) which he recognised were his first of that colour. (PROSE: The Day of the Doctor) Cindy Wu observed through his eyes that he was older than he looked, and identified the seemingly older Third Doctor as a younger incarnation by looking into his eyes. (COMIC: The Lost Dimension) Similarly, River Song could tell that he was younger than she was familiar with by looking into his eyes. (TV: Silence in the Library) He had a mole between his shoulder blades, (TV: Children in Need Special) and fillings in his teeth. (TV: 42) He went clean-shaven, (TV: Time Crash) even avoiding growing a beard over a five day period through sheer concentration. (PROSE: Prisoner of the Daleks)

While he was on the cusp of regenerating, the Tenth Doctor was observed by George Litefoot as looking to be no more than 40-years-old in human terms. (AUDIO: The Jago & Litefoot Revival)

Seeing himself as a "handsome bloke in a tight suit" with "amazing hair", (TV: The Day of the Doctor) the Tenth Doctor was noted for having vanity issues, (TV: The Time of the Doctor) to the point that he used his severed hand to prevent a complete regeneration, reasoning that he did not want to change, rhetorically asking why he would do so after seeing himself. (TV: Journey's End)

While he was possessed by Lady Cassandra O'Brien.Δ17 at New New York Hospital, Cassandra stated that he was "slim, and a little bit foxy." (TV: New Earth) Donna Noble described him as "too skinny for words", (TV: The Sontaran Stratagem) remarking that his jacket "wouldn't fit a rat", (TV: The Runaway Bride) while the Eleventh Doctor described his skinniness as a "special effect". (TV: The Day of the Doctor) Rose Tyler also noted that he was tall, skinny, and had "some really great hair". (TV: Turn Left) Jackie Tyler claimed that the Tenth Doctor "looked like a prawn, but [was] good in a crisis". (PROSE: Judge, Jury and Executioner)

The Doctor was considered attractive by people he encountered on his travels, with River Song even nicknaming him "pretty boy". (TV: Silence in the Library) Clare Pope tried to arrange a date with the Doctor upon meeting him, (TV: Partners in Crime) and Gwen Cooper, who had heard of the Doctor from Jack Harkness, commented that he was "nice" upon seeing him, having believed he would be "older", though Ianto Jones commented that "he [was] not that young". (TV: The Stolen Earth) Minnie Hooper described him as "gorgeous", "handsome" and "a looker", eagerly taking the opportunity to have a photograph taken with him, with Oliver Barnes eager to follow Minnie. (TV: The End of Time)

Despite going to great lengths to join him as a travelling companion, Donna was not physically interested in the Doctor, even being repulsed by the prospect of "mating" with him, describing him as "just a long streak" of "alien nothing". (TV: Partners in Crime) She later dismissed the notion that he was "pretty". (TV: Silence in the Library)

Rose Tyler compared the Tenth Doctor's appearance to the earnest singer of a boy band from the early 2000s. (PROSE: He's Behind You)

The Twelfth Doctor poked fun at his tenth incarnation's youthful appearance, nicknaming him "Bambi" because of his brown eyes. (COMIC: Vortex Butterflies)

Hair and grooming
The Doctor was happy to have sideburns and to have more hair than his previous incarnation. (TV: Children in Need Special) Though he initially seemed disappointed at not being ginger, he came to take great pride in his dark brown hair, wearing it in various ways throughout his adventures. He would wear it un-styled, (TV: The Christmas Invasion) slicked back, (TV: The Idiot's Lantern) in a quiff, (TV: Fear Her) or flattened forwards. (TV: The Runaway Bride) At some point, he began to experiment with back-combing his hair. (TV: Fear Her)

Wilfred Mott described the Doctor's hair to the Silver Cloak as being a "modern style", and "all sticky-uppy", (TV: The End of Time) while the Doctor himself described his hair as a "just-seen-a-ghost" hairstyle. (COMIC: The Weeping Angels of Mons) The Twelfth Doctor once recalled having "electro-shock" hair. (COMIC: Clara Oswald and the School of Death)

Main attires
The Doctor's attire was often accompanied by a light brown Duster-type overcoat, (TV: The Christmas Invasion) which the Doctor claimed had been given to him by Janis Joplin. (TV: Gridlock) He usually threw it off in preparation to flying the TARDIS, (TV: New Earth, Army of Ghosts, Smith and Jones, Human Nature, The Unicorn and the Wasp, The Stolen Earth, The End of Time) upon entering a property, (TV: The Girl in the Fireplace, Fear Her, Evolution of the Daleks, The Sound of Drums, The Sontaran Stratagem, The Doctor's Daughter) or when about to do something of which the coat would get in the way. (TV: Gridlock, Evolution of the Daleks, Utopia, Silence in the Library)

The Doctor had two main suits, a dark brown suit with blue pinstripes, (TV: The Christmas Invasion) and a blue suit with red pinstripes. (TV: Smith and Jones) Under his suits, he usually wore a dress shirt and a loose tie under his unbuttoned collar, (TV: The Christmas Invasion) or wore an open-necked shirt with a T-shirt and white or grey top underneath. (TV: Tooth and Claw, Planet of the Ood)

His shirt colours of choice were plain white, (TV: The Christmas Invasion) cadet blue, (TV: Tooth and Claw) navy blue, (TV: The Girl in the Fireplace) light blue, (TV: The Idiot's Lantern) bottle green, (TV: The Impossible Planet) scarlet red, (TV: 42) dark navy blue, (TV: Utopia) and navy red. (COMIC: The Ghost Ship) His t-shirts were coloured olive brown, (TV: Tooth and Claw) cadet blue, (TV: Fear Her) crimson red, (TV: Planet of the Ood) navy blue, (TV: Midnight) and plain white. (COMIC: The Ghost Ship)

His ties included a dark chestnut brown tie with subtle flora woven pattern on, (TV: The Christmas Invasion) a brown and blue tie with a woven geometric pattern, (TV: New Earth) a dark chocolate brown birds-eye weave tie with very subtle brown circles in a diagonal grid, (TV: School Reunion) a dark brown tie with bold swirly woven design in light blue, (TV: The Girl in the Fireplace) a blue tie with a woven geometric pattern, (TV: Rise of the Cybermen) a brown tie with repeating s-shaped woven motif, (TV: The Idiot's Lantern) navy blue tie with burgundy circles in diagonal grid, (TV: The Impossible Planet) a dark brown tie with stylised peacock-eye blue and brown motif in honeycomb grid, (TV: Love & Monsters) a herringboned burgundy background tie with mauve random flora random design, (TV: Smith and Jones) a deep navy blue background tie with red flora random design, (TV: Daleks in Manhattan) plain dark red, (TV: The Infinite Quest) a ribbed brown tie with a white and sky-blue repeating stylised flora design in diagonal bands, (TV: Utopia) a brown tie with raised diagonal stripes of navy and light blue, (TV: Partners in Crime) a burgundy tie with diagonal black stripes, (TV: The Poison Sky) a plain blue tie, (PROSE: The Mystery of the Haunted Cottage) a dark brown tie with semi-random floral design of blue flowers and bronze foliage, (TV: The Day of the Doctor) and a black and red striped design. (COMIC: Lady of the Blue Box)

His footwear choices were trainers, Converse All Stars to be specific. (TV: Time Crash) He varied the colours from cream white, (TV: The Christmas Invasion) black, (TV: Rise of the Cybermen) and red. (TV: Smith and Jones) Despite his protests, both his war and eleventh incarnations stated the trainers he wore were sandshoes. (TV: The Day of the Doctor)

Kevin Jones thought that the Doctor's clothes made him look like he worked in menswear. (AUDIO: Technophobia)

Another part of the Doctor's attire was a pair of dark tortoise-shell rectangular frame glasses, (TV: Tooth and Claw) which he called his "brainy specs". (TV: Time Crash) He required them due to becoming long-sighted after his regeneration. (PROSE: The Christmas Invasion) While on San Helios, the Doctor used his sonic screwdriver to darken the lenses to effectively turn them into sunglasses. (TV: Planet of the Dead)

Other costumes
After arriving at the Powell Estate following his regeneration, the Doctor was stripped of his predecessor's clothing and placed in a set of pyjamas and a dressing gown by Jackie Tyler, which he kept until he chose a new outfit from the TARDIS wardrobe. (TV: The Christmas Invasion)

For certain formal occasions, the Doctor would also don a white shirt with a black bow tie and tuxedo suit, accompanied by dark Converse All Stars trainers. (TV: Rise of the Cybermen, The Lazarus Experiment, Voyage of the Damned)

In his private life, the Doctor often dressed much less formally. When he slept, he wore a pair of boxers decorated with illustrations of the TARDIS. He would often sleep in a plain T-shirt, and, while he would usually choose between suits during the day, he also would occasionally wear less formal attire if cooking or spending time with Rose-the-Cat and K9. (COMIC: A Rose by Any Other Name) He also owned a pair of pyjamas which more closely resembled his pinstriped suit. (COMIC: To Sleep, Perchance to Scream)

After sentencing the Kotturuh to a lifespan of fifteen minutes, the Doctor adopted a set of Time Lord robes, coloured scarlet and orange as per his Chapter, over his usual suit. He believed it was appropriate as he was "ringing in the dawn of a new era" and explained to Brian that it was what his people had worn when going into battle, though purely ceremonial by his era. (PROSE: The Knight, The Fool and The Dead) Though he discarded the collar during the Battle of Mordeela (PROSE: All Flesh is Grass) he continued to wear the robes for a while, even on a desert planet. (COMIC: Tales of the Dark Times) He adopted the robes again during the Defence of Gallifrey. (PROSE: All Flesh is Grass)

Lifespan
The Ninth Doctor stated that he was 900 years old by the time of his travels with Rose. (TV: Aliens of London)

The Tenth Doctor himself stated his age was 903 immediately after Martha Jones stopped travelling with him, (TV: Voyage of the Damned) and later stated he was 904 years old to a rabbit in England in 1562. (TV: The Day of the Doctor)

Given his stated age of 906 just prior to his regeneration, (TV: The End of Time), and his next incarnation giving his age as 907 a few days afterwards, (TV: Flesh and Stone) this would imply that this incarnation lived only for 7-to-8 years, and if true makes this Doctor the shortest lived incarnation by a significant margin.

However, some accounts suggested his stated tally may not have been correct. When the Doctor was imprisoned on Volag-Noc, his brain was scanned for criminal activity, revealing that some of his memories dated back over 3000 years. (TV: The Infinite Quest)

Complicating the matter further is that this incarnation aged mentally while his body remained the same, due to a Time Reaver-induced coma that made seconds pass as decades from his point of view. (AUDIO: Time Reaver)

Costuming
David Tennant described his costume "geek chic". According to an interview on Parkinson, Tennant and Russell T Davies got the idea for the tenth incarnation's costume from an outfit Jamie Oliver had worn on Parkinson just after Tennant had taken the role of the Doctor. According to Doctor Who Confidential, one of the first things Tennant said after deciding to take the part was "I want a coat down to here," pointing to his ankle.

According to costume designer Louise Page, there were only four sets of the brown suit in existence, as they were pieced together from many copies of a pin-striped pair of trousers that Tennant picked out during the initial costuming process. His overcoat was made from sofa covering and there was one version that had five inches from the bottom cut off then sewn back on, as Davies and Phil Collinson had different ideas about how long it should be.

After leaving the series, David Tennant kept his costume for possible future use, stating that he would gladly return for a multi-Doctor special should he ever be asked to participate in one. (DCOM: The End of Time) Eventually, he did return in The Day of the Doctor.

 * According to a scene deleted from Human Nature (available as an Easter egg on the DVD release), the Doctor hated pears and (like his sixth incarnation) carrots.

 * Were it not for the last minute cancellation of Absent Friends due to the controversy surrounding John Barrowman, the Tenth Doctor would have joined Trinity Wells, the French newsreader and Jo Grant in the ranks of characters who have appeared in the Doctor Who, The Sarah Jane Adventures, and Torchwood franchises.
