User:BananaClownMan/Sandbox/Thirteenth Doctor

Dynamic, curious, and endlessly caring, the Thirteenth Doctor was the result of her predecessor's last stand for kindness, strongly believing in hope and practised compassion, providing help to anyone who asked.

After being separated from her TARDIS during her post-regenerative trauma, the Doctor was assisted in her recovery by Graham and Grace O'Brien, Ryan Sinclair and Yasmin Khan. Following a battle with the Stenza Tzim-Sha that resulted in Grace's death, the Doctor inadvertently brought Graham, Ryan and Yasmin with her in her search for the TARDIS.

After finding the TARDIS, the Doctor initially planned to take Graham, Ryan and Yaz back home, making several accidental trips along the way. After briefly returning to Sheffield, Graham, Ryan, and Yaz officially joined the Doctor in her travels; they shared a close, familial bond, calling themselves Team TARDIS.

Though at first she kept her past very much behind her, sharing almost nothing about herself even to her closest friends, the Doctor's history began to catch up with her when she met a new incarnation of the Master, "", and discovered that he had ravaged their home planet Gallifrey.

As her history began to unravel, with a mysterious new incarnation on the run, Jack Harkness returning and a Lone Cyberman reawakening a new Cyber-Army, she eventually found herself back on Gallifrey. Here, the Doctor uncovered the secret of her own past lives as the Timeless Child.

Unsure of her identity following the revelation of her past, the Doctor was arrested by the Judoon and imprisoned for decades in an asteroid prison for 7,000 offences. Rescued by Jack Harkness, the Doctor returned to her companions only to discover that ten months had passed for them and that things had changed while she was away. After defeating the New Dalek Army and the Death Squad Daleks, Ryan and Graham chose to resume their lives on Earth while the Doctor continued her adventures with Yaz.

A day to come
When encountering the "Vortex Butterfly", the Tenth Doctor was cryptically told that he would not be "limited" to "thirteen lives". (COMIC: Vortex Butterflies)

When the Twelfth Doctor broke his toe, Clara Oswald suggested that he regenerate to heal the injury, but he berated the idea as a waste. (PROSE: The Blood Cell)

When threatened by Captain Lundvik, the Twelfth Doctor told her she would have to shoot him, Clara Oswald and Courtney Woods, but warned that she would "have to spend a lot of time shooting [him] because [he would] keep on regenerating." Clara, during a falling out with the Doctor, later threatened to "smack [him] so hard [he would] regenerate". (TV: Kill the Moon)

While suffering from the common cold, the Twelfth Doctor, overreacting to the illness, considered the possibility of needing to regenerate. (COMIC: The Day at the Doctors)

When the Twelfth Doctor confronted in Gallifrey's Drylands after escaping from his confession dial, Rassilon contemplated using his gauntlet to force the Doctor to regenerate as a method of torture, rhetorically wondering how many regenerations the Doctor had been granted, but was interrupted before he could attack the Doctor with the gauntlet. (TV: Hell Bent)

The Twelfth Doctor once gazed at a female mannequin positioned in the doors of the TARDIS as if he held knowledge of his next incarnation being female. (PROSE: A Good Man)

During a meeting with the Curator, the Twelfth Doctor was informed that his trouble with being nice to his friends would be resolved in his succeeding incarnation. (NOTVALID: Present and Future)

The Twelfth Doctor was forced through seven false regenerations by a "regeneration vampire". With the assistance of the Eleventh Doctor, the regeneration energy he expended was returned to him. (AUDIO: Regeneration Impossible)

After the Monk invasion, the Twelfth Doctor needed to know if his companion, Bill Potts, was under the control of the Monks, and deceived her into shooting him in a rage to see if she had succumbed to the mind control, secretly putting blanks in all the guns, and faking his regeneration to complete the illusion. He made it look like the process had started, but emerged as himself to show her that he had deceived her. (TV: The Lie of the Land)

When making his case for entering the dimension of the Eaters of Light to prevent them breaking through a inter-dimensional temporal rift, the Twelfth Doctor noted that he would regenerate if the light-eating locusts killed him. (TV: The Eaters of Light)

After the Twelfth Doctor was captured by and  on a Mondasian colony ship, they debated throwing him off a hospital roof to kill him, but decided against it when they realised their uncertainty on how many regenerations he had remaining, believing they "could [be] up and down the stairs all night." (TV: The Doctor Falls)

A new body
After the Twelfth Doctor was gravely wounded by the Cybermen on the Mondasian colony ship, the regenerative process began. However, tired of "being someone else", the Doctor delayed the change for two weeks, (TV: The Doctor Falls) until an encounter with his first incarnation, Archibald Hamish Lethbridge-Stewart, and the Testimony caused the Doctor to concede that another regeneration wouldn't "kill anyone". After taking a final look at the universe and providing advice to his next incarnation, the Twelfth Doctor regenerated inside his TARDIS in an explosive fashion. (TV: Twice Upon a Time)

As they regenerated, the Doctor relived memories from each of their past lives while the Twelfth Doctor continued to give advice, recalling the magnificence of their TARDIS, (COMIC: The Many Lives of Doctor Who) Ian and Barbara, (COMIC: The Path of Skulls) the strangeness of some of their adventures, (COMIC: Card Conundrum) their love for London, (COMIC: Invasion of the Scorpion Men) and for parts of Earth outside the UK, such as New York City. (COMIC: Time Lady of Means) With the new incarnation becoming a certainty instead of a possibility, her actualised potential sent postcards to various friends as a "hello to the world", including V. M. McCrimmon and Grandfather Halfling in the City of the Saved, (PROSE: Postscript) Alistair Gordon Lethbridge-Stewart, (PROSE: When Times Change...) and the. (NOTVALID: A Lady Doctor?)

As they continued the recollections, the Doctor settled into their new body. (COMIC: The Many Lives of Doctor Who) They next remembered Gallifrey and the regeneration limit, (COMIC: Ophiuchus) how the Sixth Doctor saved the Triumvirs from the Haxeen, (COMIC: Virtually Indestructible) the Master, (COMIC: Crossing the Rubicon) how things weren't always as they appeared, (COMIC: The Time Ball) and the Last Great Time War. (COMIC: The Whole Thing's Bananas) As the regeneration finished, the Doctor noticed that her clothes no longer fitted and felt "there was something different about this body". (PROSE: Twice Upon a Time) After the Twelfth Doctor's ring fell off her finger, (TV: Twice Upon a Time) the Doctor remembered how the Ninth Doctor had to relearn to be "the Doctor" after the Time War, (COMIC: Return of the Volsci) how the Tenth Doctor helped Elizabeth Garrett Anderson become the first female doctor in England, (COMIC: Nurse Who?) and finally River Song (COMIC: Without A Paddle) and the Daleks. (COMIC: Harvest of the Daleks)

Post-regeneration
"Oh, brilliant."

- The Thirteenth Doctor's first words

Still hearing her predecessor in her head, (COMIC: The Many Lives of Doctor Who) the Doctor staggered to the console to examine her reflection, and saw her new face, a change she felt was "brilliant". Before she could do more than press a button on the control console, the TARDIS suddenly spiralled into chaos, with the Doctor being thrown out as the time rotor exploded from the damage caused by the explosive regeneration. (TV: Twice Upon a Time) As she fell towards 2018 Sheffield, (TV: The Woman Who Fell to Earth) the TARDIS vanished, (TV: Twice Upon a Time) and the Doctor maneuvered herself to fall into a train to soften her landing, knowing she would survive due to her regeneration energy still being active. (PROSE: Things She Thought While Falling)

Crashing through the ceiling of the train as it was being besieged by an alien energy coil, the Doctor saved Karl Wright and Graham and Grace O'Brien from the creature by forcing it to retreat, and took charge of the situation when PC Yaz Khan showed up with Grace's grandson, Ryan Sinclair. It was here that the Doctor was made aware that she was now a woman when Yaz addressed her as "madam". While Karl opted to leave without getting involved, the Doctor asked Yaz, Ryan, Graham and Grace to assist her, as she was still feeling uneasy after her regeneration, to the point that she collapsed. Waking up in Graham and Grace's house, the Doctor found that she and her new friends had had DNA bombs implanted in them, but was able to remove them and use the bombs to track the coil creature. Tracing the creature's signal to a warehouse with a Stenza transport pod, the Doctor, having lost everything in her pockets when falling out of the TARDIS, made a new sonic screwdriver using Stenza crystals and scrap metal, and then confronted the Stenza warrior, Tzim-Sha, who had arrived in Sheffield to hunt Karl as a rites of passage.

The Doctor and her friends were able to find Karl at a construction site, and the Doctor was able to trick Tzim-Sha into activating the DNA bombs that had been downloaded into him, and he was forced to retreat. Unfortunately, Grace was killed when she was thrown off a crane while trying to overload the coil creature. The Doctor went to Grace's funeral, where she comforted Ryan. After the funeral, she went to a charity store with Ryan and Yaz, and chose a new outfit. Needing to find her TARDIS, the Doctor rigged up Tzim-Sha's transport pod, and transported herself to where she had traced the TARDIS, accidentally bringing Graham, Yaz and Ryan with her. (TV: The Woman Who Fell to Earth)

Winding up on a spaceship crash landing on the planet known only as Desolation, the Doctor and her companions accompanied a duo of space racers, Epzo and Angstrom, while they finished the Rally of the Twelve Galaxies. (TV: The Ghost Monument) While on Desolation, the Doctor overlooked the ocean as she considered her uncertainty about her future, knowing only that it would be "amazing". (COMIC: The Many Lives of Doctor Who) Managing to survive the SniperBots hidden throughout the ruins of the planet, the Doctor uncovered a sabotaged science experiment conducted by another alien race subjugated by the Stenza, who had forced them to create weapons that eventually poisoned the planet and reduced it to a barren wasteland. Cornered by their Remnants, who attempted to read her mind, the Doctor destroyed them by igniting the gas in the air. After the space racers left the planet, having decided to end the race with a draw, the TARDIS returned to the Doctor with a redecorated interior, and the Doctor made to return Graham, Yaz and Ryan to their home. (TV: The Ghost Monument) However, the Doctor had some trouble piloting the TARDIS back to Sheffield due to the new controls, and made several accidental stops along the way. (TV: Rosa)

Returning to Sheffield
After fourteen failed attempts to return to Sheffield, the TARDIS arrived in Montgomery on 30 November 1955, where the Doctor noticed an influx of artron energy in the area, and decided to investigate. After Ryan was assaulted due to his skin colour, the Doctor was spared from having to interfere when Rosa Parks stepped up to alleviate the situation. When scanning Rosa revealed that she had been exposed to artron energy, and with her starting the Montgomery Bus Boycott just a day away, the Doctor discovered that a mass murderer from the far future named Krasko was attempting to prevent Rosa from initiating the boycott in the hope that doing so would prevent equality between races, but he could not harm anyone due to a neural restrictor in his brain, forcing him to use a temporal displacement weapon instead. Engaging Krasko in a game of out doing each other, the Doctor, Yaz, Ryan and Graham were able to keep history on track, even realising that they were always part of the events, and ensure Rosa was arrested after refusing to follow James Blake's order to move seats for Graham to sit on the bus. (TV: Rosa)

When Yaz was having her "time of the month", the Doctor took her to the TARDIS Hungarian bathroom, and told her of the time she met Amelia Earhart in her eleventh incarnation. (PROSE: Chasing the Dawn)

The Doctor eventually got the TARDIS to Sheffield, but decided to stick around for tea at Yaz's flat after she was invited. She met Yaz's father and sister, Hakim and Sonya, and went to retrieve an unclaimed package for Hakim with Ryan when Yaz left to pick up her mother, Najia. Going to the neighbour's flat, the Doctor and Ryan met Dr. Jade McIntyre, and found that the neighbour had been killed by a giant spider. When Graham arrived claiming to have found another giant spider in his house, the Doctor, Ryan and Graham were brought by Jade to her laboratory, where the Doctor found that a Robertson Luxury Hotels hotel was at the epicentre of the spider sightings. Arriving at the hotel to find Yaz and Najia being threatened by a massive spider with the hotel owner, Jack Robertson, the Doctor investigated underneath the hotel, and found that an old mine filled with waste disposed by Robertson's disposal company had caused a specimen from Jade's lab that was thought deceased to mutate.

The Doctor, Graham, Ryan and Yaz, working with Robertson, Najia and Jade, were able to trap the entire brood of spiders in Robertson's panic room, and Robertson killed the spider mother with a gun, much to the Doctor's outrage, as the spider was already dying due to being too large to support itself. Later that night, as the Doctor prepared to depart, Yaz, Ryan and Graham returned to the TARDIS, explaining that they had all chosen to continue travelling in the TARDIS; Graham wished to have something to do to help him cope with Grace's passing, Ryan wanted more excitement in his life, and Yaz yearned to see more of the universe. Though the Doctor tried to persuade them to reconsider due to her dangerous lifestyle, the trio accepted the risks, pulling the dematerialisation lever together to continue their journeys as Team TARDIS. (TV: Arachnids in the UK)

Early travels as Team TARDIS
The Doctor took her friends to a singing waterfall made of pink crystals, a unicorn sanctuary on a lost moon, the Big Bang, (PROSE: The Good Doctor) and the upward tropics of Kinstarno for rain bathing. (TV: The Tsuranga Conundrum) After Team TARDIS encountered the Death Eye Turtle Army, the Doctor found herself having to "profusely" apologise to Graham for taking a risk he disagreed with. (TV: Demons of the Punjab) They also visited the Great Kalisperon Bike-Off. (TV: Spyfall)

The Doctor and her friends went to see Elizabeth II's coronation in 1953, where the Doctor photobombed the picture of the royal family on the balcony of Buckingham Palace. She then saw that Eva De Ville, who had been sent to assassinate her, was leaving the scene, but her attempt to interfere resulted in Queen Elizabeth being taken by De Ville by mistake. Tracking De Ville, the Doctor landed the TARDIS on the Phasmatodea Cartel representative who hired De Ville and was able to retrieve the Queen. (COMIC: Where's the Doctor?)

Hoping to stock up on spare parts for the TARDIS, the Doctor went to a junk galaxy to scavenge, where Graham accidentally set off a sonic mine that knocked Team TARDIS unconscious for four days. Fortunately, the Tsuranga medical ship had been nearby when the mine detonated, and they had been brought on board for treatment shortly after the blast. Upon regaining consciousness, the Doctor found out that the rescue craft was on a preprogramed route and could not take them back to the TARDIS until docking at Resus One. As the Doctor tried to find a way to get back to her TARDIS, a Pting managed to get aboard the ship, and began eating it. The Doctor stunned the Pting by making it eat a device that overloaded it with energy and ejected it back into space. (TV: The Tsuranga Conundrum)

At Yaz's urging, the Doctor took Team TARDIS to 1947 during the Partition of India, so Yaz could learn more about the life her grandmother, Umbreen, had had before she moved to Sheffield, as Umbreen refused to talk about that time of her life. Meeting Umbreen and her fiancé, Prem, who Yaz claimed not to be her grandfather and had no knowledge of, the Doctor discovered Thijarians, a species of known assassins, near the body of a deceased holy man and assumed they were responsible for his death. However, the Thijarians revealed that they no longer killed, having been absent during the destruction of their planet, instead taking the role of witnesses to watch over the dying as they could not do this for their own people, and also revealed that Prem was destined to die during the Partition. Knowing history had to play out, the Doctor officiated the marriage of Prem and Umbreen in the place of the holy man, before Prem was killed on the orders of his brother, Manish, for marrying a woman of a different religion. (TV: Demons of the Punjab)

During a visit to see Albert Einstein in 1905 Switzerland, Team TARDIS found that the children of Bern had fallen ill, and that giant spiders and rats were roaming the streets. When the Doctor used the ultraviolet setting on her sonic screwdriver, she found that alien starfishes were feeding off the children's imagination and creating the psychic manifestations. The Doctor tried to trap the starfishes by using Einstein as a lure, but his imagination overloaded the aliens into creating dark visions until Mileva Einstein was able to calm his mind. With the starfishes secure, Team TARDIS departed Bern to take them somewhere safe. (PROSE: Einstein and the Doctor)

While travelling in the Time Vortex, the TARDIS was boarded by a Kerb!am Man to deliver a fez the Doctor had ordered in a previous incarnation. On the packing slip, Yaz found a message begging for help. The Doctor took the team to Kerb!am to find the source of the distress call and they began investigating the mysterious disappearances of workers. The Doctor eventually determined that the Kerb!am AI itself had sent the distress call in response to the disappearance of the employees. Shortly after making this revelation, Ryan deduced that Charlie Duffy, a maintenance worker, was behind the disappearances, and Charlie revealed his plan to have an army of Kerb!am Men deliver packages with bombs in the bubble wrap to kill Kerb!am customers and prevent automation from completely replacing a human workforce. The Doctor was able to reprogram the robots to open their own packages and detonate the explosives within, destroying the army and killing Charlie when he refused to escape with the Doctor. (TV: Kerblam!)

Attempting to see the coronation of Elizabeth I, the TARDIS instead brought Team TARDIS to Bilehurst Cragg in the 17th century, where the Doctor interfered in a witch trial, though she failed to save the accused, Mother Twiston, from drowning. Disgusted at the callousness of the landowner, Becka Savage, the Doctor tried getting her to see that there was no supernatural evil in her village, but the arrival of King James I hampered her attempts, especially when he dismissed her due to her gender. Deciding to investigate elsewhere with Yaz while Ryan and Graham remained with King James, the Doctor visited Twiston's granddaughter, Willa, and learned of the unexpected depletion of the local fauna. The Doctor, Yaz and Willa investigated Old Mother Twiston's grave and saw her rise as a Morax. As Graham and Ryan arrived with King James and Becka in tow, the Doctor instructed Graham, Yaz and Ryan to follow the Morax as she questioned Becka. However, when she realised that Becka knew more than she was letting on, Becka accused the Doctor of being a witch, and King James ordered her drowned.

As she prepared to face a witch trial, the Doctor discovered that Becka was infected by the Morax Queen when she chopped down the lock keeping the Morax DNA imprisoned, thinking it was only a tree. Escaping her bonds after being submerged, the Doctor exposed Becka just before the Morax Queen took control of her and kidnapped King James, planning to turn him into a vessel for the Morax King. However, the Doctor was able to reactivate the prison to suck the Morax back in. Unfortunately, as the queen resisted, King James burned her with a torch, causing her to dissolve. Disgusted with the king, the Doctor refused to speak to him until she departed, with King James promising the end the witch trials and have the events in Bilehurst Cragg stricken from the history books. (TV: The Witchfinders)

Team TARDIS next arrived at a pizza parlour in New Port City, where they discovered the body of Iz. The Doctor and Graham investigated Iz's local Grey Zone Mall, but found that the posh dress she was wearing wasn't sold there. The Doctor attempted to find the teleportation coordinates to the Black Zone Mall, but instead, Graham and the Doctor found themselves outside the city next to the teleportation system's core. Needing to bypass the core's teleportation block, they returned to the pizza parlour and used spray cheese to provide a forcefield while Graham drove a moped to the core. The Doctor and Graham rescued Ryan and Yaz from having their sperantium harvested, as the city's dictatorial mayor, Ronan Sumners was accidentally ported into a Pizza-Porter oven. (PROSE: Gatecrashers)

On a whistle-stop tour of the Seven Wonders of the Universe, Team TARDIS arrived in the Jewelled City of Glude to find it a burning wreck, before witnessing the destruction of the Twelve Moons of Dhost by missile. The Doctor tracked the source of the destruction back to a film director in Follyrood, who had filmed the destruction for use in a movie starring Errol Flynn. The Doctor unleashed a box of data bugs, who lived on Dhost, that destroyed the director's film equipment and put an end to his destruction spree and his career. (COMIC: The Greatest Movie Never Made)

The Doctor and Team TARDIS travelled to the planet Gatan, arriving in the City of Radiant Stone in the midst of war. As the group split up to help a lost girl called Tondi find her mother, the Doctor and Yaz were attacked by a looter called Gorny when the Doctor asked him for directions. The Doctor was able to subdue him, but they quickly got caught in the crossfire between two enemy warriors named Tumat and Kraytos. The Doctor learned from Gorny that the two of them had been fighting for months, causing the destruction of the entire city, but, upon attempting to confront them, she was grabbed by a robotic reporter named Sandola Dell and teleported to her boss, Berakka Dogbolter. Berakka revealed the history of the warriors to the Doctor and how she was using enterprise to profit off of their fighting and attempted to kill the Doctor to protect her plans, before being interrupted by Graham and Ryan. Returning to Gatan, the Doctor helped lure Tumat and Kraytos into a teleport pad and forced them to re-emerge in the same place as one combined being. With the new Chimera stopping the war, the Doctor shut down Berakka's network and bade farewell to the Chimera. (COMIC: The Warmonger)

Team TARDIS becomes a family
After halting a war on the planet Lobos between the Loba and the human colonists, the Doctor and her companions departed in the TARDIS. When they attempted to return to retrieve Ryan's mobile phone, the TARDIS slipped almost six-hundred-years into the future, where the planet was now ruled by human zealots, served by slave Loba, whose religion was largely based on a misinterpreted joke made by Graham, who was worshipped by them as "the Good Doctor". First relegated to the background and having to do things through Graham's authority, the Doctor came into conflict with the ruling Temple of Tordos, and had to fight an artificially enhanced Loba named Tromos to the death. In the end, the Doctor succeeded in uncovering the lie of the zealots, setting the record straight and brokering a lasting peace between humans and Loba. (PROSE: The Good Doctor)

When the TARDIS landed in 2018 Norway, Team TARDIS found Hanne, a blind girl left to fend for herself in a boarded-up house with a monster seemingly hiding in the woods outside. While trying to help Hanne find the monster, the Doctor discovered a mirror leading to another plane of existence, and ventured through it with Yaz and Graham, where they found Hanne's father, Erik, living with his supposedly deceased wife, and what appeared to be Grace. Evaluating the facts with Yaz, the Doctor realised that her grandmother's old bedtime stories about the Solitract were real and that she had discovered the living universe. Thinking she had walked Graham into a trap, the Doctor tried to convince him and Erik to leave, but both men refused to lose their wives again, though Graham was convinced of Grace being a fake when she reacted with indifference to Ryan's safety. With everyone but Erik evacuated, the Doctor convinced the Solitract into forcibly releasing him by offering herself in his place. Now alone with the Doctor, the Solitract explained that it was not being malicious, but was lonely and only wanted company. The Doctor convinced the Solitract that its existence was threatened by objects foreign to its universe, including her, and it reluctantly let her go. (TV: It Takes You Away)

After the TARDIS passed through an energy anomaly, it landed in 451 AD Gaul, where Graham and Ryan were separated from the others during an attack, and the Doctor and Yaz were "captured" by Attila the Hun to serve as his new "combat witches" against the power of the mysterious Tenctrama. The Doctor eventually determined that the Tencrama were survivors of a catastrophe on a distant planet who now sought to gain power from the psychic energies generated by the deaths in the wars they were escalating on Earth. The Doctor realised that the Tenctrama's process depended on them having spent the last thousand years subtly "engineering" humanity to be suitable energy sources for them, with the result that the Tenctrama would be contaminated if they absorbed anyone who had been treated with healing technology, such as a healing gel the Doctor had used. The Tenctrama were caught by surprise when they absorbed a horse that the Doctor had healed, the disruption giving the Doctor time to reconfigure their equipment and project the Tenctrama energy into Earth. (PROSE: Combat Magicks)

The Doctor and her friends visited Adamantine, where the entire civilisation lived inside the hollowed shell underneath the planet's exterior, and befriended Ash, one of the native silicon-based life forms, and the daughter of the planet's first scientist, Basalt. The Doctor soon determined that the civilisation was under threat as the exterior of the planet began to crack and let in water which threatened to cool the lava that Basalt's people needed to survive. While Graham and Yaz tried to calm the people, the Doctor and Ryan travelled up to the surface with Ash, learning that the cracks were caused by a mining expedition that had been abandoned after the original team was killed by an exploding gas pocket while leaving their equipment running. The Doctor was able to contact the original company and obtain the necessary command codes to shut down the equipment and use it to repair the worst of the damage threatening Basalt's home city. (PROSE: Molten Heart)

When the TARDIS picked up nine separate distress signals from planet Ranskoor Av Kolos in 5425, Team TARDIS found Greston Paltraki alone in his ship, just as Tzim-Sha contacted him, demanding Paltraki give back what he stole in return for his crew's safety. The Doctor had Paltraki lead her and her companions to Tzim-Sha's base for a prisoner exchange and Graham told her that he planned on murdering Tzim-Sha to avenge Grace, with the Doctor threatening to expel him from the TARDIS if he did. Arriving at Tzim-Sha's "edifice", the Doctor took the package directly to Tzim-Sha and learned that, after the DNA bombs caused his teleporter to malfunction and strand him on Ranskoor Av Kolos, he had fooled the Ux, a rare species capable of dimensional engineering through pure thought, into seeing him as their god. He convinced them to use their powers to heal him from his near-death and create a weapon that could miniaturise planets, killing the inhabitants in the process, so that Tzim-Sha could take revenge on worlds that had opposed the Stenza. However, the Doctor, with help from Yaz, was able to get the Ux to see their mistake and return the planets to their original places. With the planets' return stabilising the universe, the Doctor found that Graham and Ryan had trapped Tzim-Sha inside one of his own trophy cases as punishment, with the Ux sealing the edifice to ensure no-one would be able to free him. (TV: The Battle of Ranskoor Av Kolos)

Investigating the Catastrophia
Attempting to reach the Ninth Moon of Quezzeltrax, the TARDIS instead landed in 1601 Bohemia, where the Doctor, Graham, Ryan and Yaz joined Tycho Brahe and Johannes Kepler at a gathering of scientists laid out by Baroness Dagmar Ruskovitch, a meeting the Doctor could not remember from historical accounts. At the gathering, she and Ryan discovered a ritual and were psychically attacked by a monk named Dominik. However, the Doctor was able to turn the attack back on him, knocking him out and giving her and Ryan time to investigate. When doing so, the Doctor was attacked by energy and left paralysed and continually muttering nonsense. Ryan, carrying her, was later cornered by two robed figures from Dominik's Brethren, just as the Doctor came around and fended them off. Regrouping with the rest of her friends, the Doctor learnt that Ruskovitch was trying to prevent the summoning of a twisted figure in the castle's cavern, despite the Doctor believing her to be the cause, just as it fully manifested in the form of the Doctor herself. With Ruskovitch revealing herself and Dominik to be Knights of the Solitary Sword, who were dedicated to protecting the universe from the Catastrophia, the Doctor and Ruskovitch teamed up to seal its Herald away again, at the cost of Brahe's life. (COMIC: Herald of Madness)

On Acantha, the Doctor and her companions discovered a collapsed mine and were caught in a mag-storm, becoming separated from Ryan. Rescued by a team of Mobox, they were taken to a nearby Icarus Incorporated colony where the Doctor used her psychic paper to get an audience with the Governor K’Lass. He agreed to let Graham and Yaz attempt a rescue, but insisted the Doctor stay. The Doctor was shown around the colony by the Governor’s human assistant, Rodney, and eventually got him to confess he thought something was wrong about the mine collapse, whilst secretly disarming his weapon. They discovered an underground area where humans had collected 600 Mobox under the covers of the mine collapse to harness their power, which Rodney revealed he was part of and had led the Doctor down there believing she was from a rival company. Furious the Doctor swore she’d tear down the obscenity and revealed his gun was useless. Fleeing from security he summoned, the Doctor was reunited with her companions who had discovered the chamber where mag-storms were being generated. In the chamber, she disabled the captive Mobox’s restrains and used a gravitron lowered the gravity around the colony to prevent conflict, enabling the peaceful arrest of Rodney and his co-conspirators. (COMIC: The Power of the Mobox)

The Doctor attempted to rescue a worker, Harold, during a power plant meltdown on Segonus IV but he refused her help and perished, to her horror. Wanting to know why, she discovered Berakka Dogbolter had used her control of the media to brand the Doctor as a terrorist. Telling her companions to stay in the TARDIS, the Doctor angrily confronted Berakka and threatened to take away everything she owned. Krizanthia Kalos, a child of chaos, interrupted them and revealed she revered the Doctor as the “Mistress of Chaos” and had come to kill Berakka in her honour. The Doctor distracted her until her companions managed to immobilise her guards, however Berakka attempted to flee and in the confusion Krizanthia teleported herself, the Doctor, Berakka and Graham away to another part of Venus. Krizanthia used the Eye of M'Dulia to open a portal to the Catastrophia, claiming the Doctor would be embraced at last. As they were pulled in, the Doctor was able to guide Graham and Berakka to a logic cube within the chaos of the Catastrophia. There she discovered the Herald chained, and learnt to her horror that the Herald was not a template based on her but a possible future version of her. The Sanity revealed itself as the creator of the logic cube, claiming to be another possible future version of the Doctor, and explained its plan to use the Herald to break the Catastrophia into normal reality, destroying it at the cost of trillions of lives. The Doctor distracted the Sanity so Berakka could attack it and she and the Sanity fell onto the Herald, causing a massive explosion which left only the Doctor. She, Graham and Berakka were rescued by Mother G flying the TARDIS along with Yaz and Ryan. Back on the Venus, the Doctor asked Mother G who she was but received cryptic answers. Berakka believed this incident had confirmed her beliefs that the Doctor was a monster and left still intending to tell everyone about her. Team TARDIS cheered the Doctor up by showing her Sharon Allen’s more accurate coverage of her actions on a rival news feed. (COMIC: Mistress of Chaos)

Christmastime exploits
While staying in a cabin during a snowstorm, the Doctor used her sonic screwdriver to light a Yule Log, which she rested by as she repeatedly and comically missed the various monsters crawling around the cabin. (NOTVALID: Festive Thirteenth Doctor Yule Log) While on an unnamed planet, the Doctor received a phone call from Santa Claus, telling her he needed her help with an emergency. She headed straight to Lapland to meet with him. Upon her arrival, Santa told the Doctor that his sleigh had lost its magical flying power. The Doctor lent him her TARDIS to substitute the sleigh, on the condition that he return it once he was finished. (WC:  'Twas the Night Before Christmas)

Facing the reconnaissance scout Dalek
After enjoying nineteen New Year's celebrations, Team TARDIS was alerted to strange signals coming from Sheffield, and met Mitch and Lin at an archaeological site in the sewers, where the Doctor obtained DNA from slime on the wall. Deciding to go to Graham's house, Team TARDIS found Ryan's absent father, Aaron Sinclair, had arrived to reconnect with his son. After Ryan left to hear his dad out, the DNA analysis in the TARDIS completed, and the Doctor found that it belonged to a Dalek. Tracking down Mitch, the Doctor learned that the Dalek had been buried on Earth since the 9th century and that it was controlling Lin. Resolving to stop the Dalek after Ryan returned, and accidentally leaving Graham behind with Aaron, the Doctor, Yaz, Ryan, and Mitch tracked Lin to a warehouse, where the Dalek had constructed a new casing from scrap.

Revealing her identity to the Dalek, the Doctor demanded it leave the planet while it had the chance, but it refused. Collecting Graham and Aaron, the Doctor tracked the Dalek to the Government Communications Headquarters, where she and her team melted the Dalek's casing with Aaron's microwave oven. The victory was short-lived when the Kaled mutant inside took control of Aaron's body, forcing the Doctor to take it back to Skaro. However, the Doctor opened the TARDIS doors into a supernova, removing it from Aaron. (TV: Resolution)

Going everywhere
Stopping to watch the Sentient Nebulae on Blecplam Two and a Half in 3912, the Doctor and Team TARDIS encountered a rip in time that the Doctor recognised as the same anomaly she had encountered in her tenth and twelfth incarnations. As a hand emerged from within the anomaly, the rip vanished as before, but the Doctor was able to track it down again to an unnamed planet, where they successfully saved the trapped man, Dr. Leon Perkins, before being imprisoned by the Grand Army of the Just. While imprisoned, Perkins explained that he had become stuck in a time-loop when he and his superior, Dr. Irene Schulz, activated the prototypes of their prototype vortex manipulators, only for his to malfunction. Using her sonic screwdriver, the Doctor opened their containment cell and Team TARDIS escaped with Perkins back to the TARDIS safely, where he attempted to hijack the ship at gunpoint, only for the Doctor to tell him that the TARDIS had neutralised his weapon, and she instead let him explain himself over a pot of tea, with Perkins revealing that he and Schulz had come into contact with an alien, whom they dubbed "the Hoarder", who forced them to steal treasures from across the universe using their time travel technology, as well as children to act as hostages. When they refused to bring him new hostages, Schulz was injected with a toxic substance as punishment. When the Doctor took them to the Hoarder's resident planet to find her, Schulz explained that she had Perkins suspended in the time loop in order to keep him from the Hoarder's grasp, until she could find an antidote for the toxin in her system, which she would have also used as an inoculation on Perkins.

Bringing the ingredients Schulz had already gathered back to the TARDIS, the Doctor put together an antidote that successfully cured Schulz. Returning to the Hoarder's lair, Perkins and Schulz proclaimed to the alien that they were done working for him, while Team TARDIS got to work freeing the hostages, as well as tipping off the Time Agency to the hoarder's activities. Surrounded by Time Agents, the Hoarder tried to escape using Perkins' vortex manipulator, unaware that it was still faulty, resulting in him being frozen in a time loop. Team TARDIS parted ways with Perkins and Schulz, assured that they would work to get the children home and the treasures back to their rightful places. (COMIC: A New Beginning)

When Ryan and Graham suggested throwing a surprise birthday party for Yaz, the Doctor went to look for a cake, balloons, and birthday candles. She bought a Sontaran Frosted Boom Cake at a bakery on Sontar, obtained some Zeppelins for balloons from London during the Blitz, and took a candled Candelabra in Paris. When the party began, the cake exploded and covered Team TARDIS in pink chocolate, but Yaz was happy nonetheless. (PROSE: Dr. Thirteenth)

Arriving in Guelder in the early 16th century, the Doctor was stunned when her companions revealed the knowledge they had gained of the Guelders Wars from a historical podcast hosted by Bethany Brunwine called Hidden Human History. Exploring, Team TARDIS encountered a horde of Stilean flesh eaters, an alien species that were able to gradually take on the traits of different lifeforms after consuming their blood, one of which took a bite out of the Doctor. Tracking the Stilean flesh eaters to North Carolina in 1711 during Cary's rebellion, and to Canada in the 1860s during the Battle of Ridgeway, the Doctor noticed that the creatures were gradually becoming more human the more they fed, just as Dr. Leon Perkins and Dr. Irene Schulz arrived, both having joined the Time Agency since their last encounter with the Doctor.

As they continued to track the creatures, the crew became aware that they were continually visiting times and places that had been covered in Hidden Human History. To learn how the podcast was connected to their recent travels, Team TARDIS paid a visit to Bethany Brunwine at her home in 2019 London, where they discovered that she was the Stilean flesh eater that had bitten the Doctor upon their first encounter. Bethany revealed that consuming the Doctor's blood had slowed her ageing, allowing her to live on Earth among humans for centuries, and that the podcast had been inspired by her encounters with the Doctor in the past. After ending their visit with Bethany, Yaz questioned if the Doctor would give Hidden Human History a listen, to which the Doctor agreed, believing it would be rude not to after "[she] helped it happen". (COMIC: Hidden Human History)

Wanting to deal with "unfinished business", the Doctor returned to Gladstone's warehouse to find the escaped alien prisoner her twelfth incarnation had investigated with Harry Houdini.

With Billy's assistance, Team TARDIS was able to rescue Houdini and his wife from King. (PROSE: Who-Dini?)

Going to meet with Pythagoras in 500 BC Crotone to return his sunglasses, Team TARDIS found that his daughter, Myia, had been possessed by Zaris of the Argomeld, a race that grew from microbial size by transferring across host bodies. When the Doctor realised that Zaris would destroy Myia and the surrounding area when it jumped to its home dimension, she offered to help Zaris leave safely by using Pythagoras's mathematical tetractys sequence. Once Zaris had returned home, the Doctor made to return the sunglasses, only for Pythagoras to reveal that they weren't his. (PROSE: The Pythagoras Problem)

The Doctor then took her friends to Paramount Studios in 1961 to return the sunglasses to Audrey Hepburn while she was filming Breakfast at Tiffany's.

However upon tracing the thief’s TARDIS, Team TARDIS discovered the culprit was the Corsair. After they escaped a pub brawl, the Corsair invited the Doctor to help on a heist which the Doctor accepted, after taking a moment to reflect on her foreknowledge of the Corsair’s eventual fate. They rescued a star whale from Raddplina, however the Corsair abandoned the Doctor’s companions when authorities arrived. Despite the Doctor’s anger, the Corsair insisted they deliver the whale to her employer first, who the Doctor was horrified to discover was the Hoarder. The Hoarder had them imprisoned however, after having a proper talk in a cage, they escaped and returned to Raddplina for Doctor’s friends.

Answering a distress call apparently from the Shadow Proclamation, the Doctor travelled to a mysterious moon that she discovered were parts of her TARDIS from alternate timelines, and that the TARDIS had sent the signal, brought together by Siblings Different and Sibling Same, who wanted revenge on the Doctor for their anomalous existence, caused when the Time War ended. Their plan was to use their patchwork TARDIS to undo the Time War, but it immediately starting falling apart upon activation, threatening the stability of the universe, but disaster was averted when Same sent his paradox energy into Different and returned the TARDIS pieces to their own timelines, killing himself in the process. (PROSE: The Paradox Moon)

Foiling the Kasaavin
When she was asked to investigate a series of attacks on all spies across Earth by MI6, the Doctor contacted her old friend "O", and learnt that the attacks were linked to VOR CEO Daniel Barton and aliens from another dimension called the Kasaavin. When Team TARDIS and "O" went to confront Barton, he fled in his private jet, where, after Barton escaped, "O" revealed that he was actually and was also behind the attacks. As he left her and Team TARDIS in the crashing plane, the Doctor was taken by the Kasaavin, who transported her to their realm.

As she explored the area, the Doctor encountered Ada Lovelace, who seemed to naturally be able to enter the dimension. Arriving in 1834 London, she learned that the Master was following her and that his plan covered various time periods. Using the Silver Lady figurine Ada used to enter the Kasaavin's realm, the Doctor and Ada arrived in 1943 Paris, where they were rescued from the Master and the Nazis by Noor Inayat Khan. Contacting the Master with a psychic link, the Doctor arramnged to meet him at the top of the Eiffel Tower, where she learned that the entire plan was to get her attention so the Master could tell her that Gallifrey had been destroyed. Leaving the Master to be arrested by Nazis after she had Noor frame him as a traitor, the Doctor stole his TARDIS and, with help from Ada and Noor, foiled the Kasaavin's plan, allowing them to take the Master back to their realm with them as they fled.

After returning Ada and Noor to their original time periods, the Doctor returned to Gallifrey, only to learn it had been ravaged and left in flaming ruins. In a hologram message left by the Master, she learned that it was his doing, as an act of revenge after learning about the Timeless Child and how the Time Lords' history had been built on a lie. The Doctor then travelled with Graham, Yaz and Ryan for some time in a weary mood, until they convinced her to open up about her past to them. (TV: Spyfall) The Doctor would occasionally return to her destroyed home planet, while also trying to find evidence of the Master escaping the Kasaavin. (TV: Fugitive of the Judoon)

Identity crisis
While undertaking another search for the Master, the Doctor was alerted to the Judoon placing a zonal enforcement field around Gloucester, (TV: Fugitive of the Judoon)in 2020. (TV: Can You Hear Me?) Team TARDIS slipped through the enforcement field to a coffee shop, which they left to search for the Judoon, as Graham was teleported away. Find the Judoon wielding a temporal isolator at an apartment, the Doctor posed as an Imperial Regulator and discovered that they were hunting a fugitive. Allowed time to peacefully dissolve the situation, the Doctor, Ryan and Yaz entered the home of Lee and Ruth Clayton, finding that, although they both registered as human, Lee was hiding something alien. After being told by Lee to take Ruth away while he confronted the Judoon, the Doctor and Ruth quickly hid in the Gloucester Cathedral, while Yaz and Ryan stayed to manage the Judoon.

At the lighthouse, the Doctor found a buried a TARDIS in the shape of a police box, just as Ruth regained her memories from a Chameleon Arch and revealed herself as another incarnation of the Doctor, and teleported herself and the Thirteenth Doctor inside her TARDIS. As they began squabbling in confusion on not remembering the other, the two Doctors were caught in a tractor beam and brought to the Judoon rocket, where they found the Judoon working for a Gallifreyan named Gat, whose nature convinced the Thirteenth Doctor that both Gat and Ruth were from her past, despite not remembering either of them. After Gat was killed by a tampered gun, the two Doctors fled the Judoon in the TARDIS, and the Thirteenth Doctor was dropped off back in Gloucester, where she was found by Yaz and Ryan, who told her that they had met Captain Jack Harkness. Back in the TARDIS, Graham relayed Jack's message to the Doctor; "Beware the Lone Cyberman. Do not let it have what it wants." The TARDIS alarms then sounded, notifying her of alerts from three different locations, and Team TARDIS took off to investigate. (TV: Fugitive of the Judoon)

Dropping off Ryan in Peru and Yaz and Graham in Hong Kong, the Doctor herself travelled to a beach in Madagascar, where she found a naval officer in danger. With help from the nearby Suki Cheng and Aramu, the Doctor dragged the man out of the water, but he then exploded into dust after scales emerged all over his body. After being called to a hospital in San Pedro by Ryan, the Doctor found a young girl with the same symptoms had also exploded into nothing. She took both Ryan and the girl's friend, Gabriela Camara, aboard the TARDIS and left to meet Graham and Yaz, who had gained the company of Jake Willis and his sick husband, astronaut Adam Lang, all of whom have recently been under attack from men in hazmat suits with alien guns. She took them all aboard the TARDIS, except for Yaz and Gabriela, who insisted on staying to do some research, and ventured back to Madagascar, where Aramu told them about strange bird behaviour. They used Suki's lab to do some tests and discovered that Adam had been infected with an alien pathogen.

While working on an antidote, the Doctor then got a comm dot call from Yaz that made her realise that Suki was behind it all. As Suki, revealing herself to be an alien, teleported away, the birds came crashing through the window, necessitating the team to flee to the TARDIS. Inside the TARDIS, the Doctor administered the antidote on Adam and set up the TARDIS to synthesise it. She tracked Yaz's location to a gyre at the bottom of the Indian Ocean, where they then found Suki, who explained about Praxeus before succumbing to the pathogen herself. The Doctor received the finished antidote from Jake and Adam and set Suki's ship to take off and disperse the antidote into the atmosphere. After hurrying back to the TARDIS, the Doctor discovered that Jake had not followed them.

Following the alert to a Bimaristan, the Doctor found a young woman named Tahira hiding from a a Chagaska. While heading back to the TARDIS with Tahira, the Doctor got multiple calls from her companions, each complaining about strange events in Sheffield. Picking up her friends with Tahira in tow, the Doctor hooked Graham to the telepathic circuit so the TARDIS could follow his strange visions, which saw Team TARDIS and Tahira travelling to a space platform in the far future. Finding a geo orb stuck between two planets in an everlasting extinction event, Graham told her that this was his vision, and that there was a woman trapped in the orb.

After Tahira and Team TARDIS disappeared exploring the ship, the Doctor was confronted by Zellin, who revealed that he had set the trap for her to unlock his long-imprisoned partner, Rakaya, from the geo orb. When Rakaya was released, she sent the Doctor into a dream state, in which she saw the Timeless Child standing before a wormhole. The Doctor awoke to find herself, Team TARDIS and other prisoners restrained with hand-cuffs, but soon freed herself and the other prisoners. The Doctor then lured Zellin and Rakaya to Aleppo and trapped them both inside the geo orb with the Chagaska after Tahira conquered her fears of it and tamed the beast. Back in the TARDIS, after she had returned Zellin's prisoners back to where they belonged, Graham confided in the Doctor about his fears of his cancer, but she had no idea what to tell him, and decided, as a distraction, to take Team TARDIS to see the creation of Frankenstein.

While being taught a dancing routine by their hosts, the Doctor, already picking up bad "vibes" from the house, realised that something was amiss due to the absence of Percy Shelley. As strange happenings persisted in the house, the occupants soon found themselves trapped in various areas of the house, until the Doctor worked out that they were being deceived by a perception filter.

Still trapped in the house, the occupants saw the arrival of the "Lone Cyberman", Ashad, who was looking for "the Guardian". Confronting the Cyberman on her own, the Doctor learned that he was in search of the Cyberium, an AI which contained all the knowledge of all Cybermen, and that he had arrived from the Cyber-Wars. After finding Percy Shelley hiding in the cellar, the Doctor figured out that he was the Guardian, as he had found the Cyberium and it had been absorbed into his body, but its possession was slowly killing him. Despite some disagreements from her companions, the Doctor took the Cyberium from Shelley and gave it to the Cyberman, who then vanished. Bidding their farewells, Team TARDIS left to find and stop the Lone Cyberman from restabilising the Cyber-Empire in the far future, using coordinates Shelley had deciphered from the Cyberium. (TV: The Haunting of Villa Diodati)

The truth of the Timeless Child
After constructing various countermeasures to combat the Cybermen, Team TARDIS travelled to a refugee planet in the far future in the aftermath of the great Cyber-Wars, finding only a couple of human survivors left, but they were unable to protect them when Cyberdrones attacked the settlement and destroyed the Doctor's contraptions. Realising there was no hope in defending the settlement, the Doctor told everyone, including her companions, to flee to the rescue ships while she caused a diversion, but later found that Ashad's Cyberguards had separated Ryan and the settler, Ethan, from the others in their retreat.

Stealing a Cyberfighter after briefly overpowering Ashad, the Doctor, Ryan and Ethan left the planet and flew into space, hoping to meet the others at the Boundary. (TV: Ascension of the Cybermen) While experiencing visions of an Irish Gardaí, (TV: The Timeless Children) the Doctor responded to a call from Ashad, where he gloated about his inevitable victory. Arriving on the planet of the Boundary, the Doctor, Ryan and Ethan met Ko Sharmus, who led them to the Boundary, which opened to reveal a portal to Gallifrey. Before the Doctor could figure out what was happening, jumped out the Boundary, (TV: Ascension of the Cybermen) and forced the Doctor to accompany him to Gallifrey, where she was placed in the Matrix to show her the history of the Timeless Child, an entity who had the ability to regenerate indefinitely and whom the early Time Lords had experimented on and studied to gain the ability themselves. The Master then revealed that he had discovered the Timeless Child was actually the Doctor in a previous life that she could not remember. With encouragement from a Matrix projection of her "fugitive" incarnation, the Doctor managed to escape from the Matrix by overloading it with her memories, and was reunited with Team TARDIS, Ko Shamus and the refugees.

Together, they destroyed the Cybercarrier that had landed on Gallifrey and retreated to a vacant TARDIS after finding Ashad's shrunken corpse, having been killed by the Master, though the death particle, which the Cyberium had created through Ashad, remained inside him. (TV: The Timeless Children) Sending Team TARDIS and the refugees to Sheffield in March 2020, (TV: The Timeless Children, Revolution of the Daleks) the Doctor went to confronted the Master, who had created a race of CyberMasters from the bodies of the Time Lords.

The Doctor ran and stole another TARDIS before Ko Sharmus activated the particle, seemingly destroying the Master and the CyberMasters. (TV: The Timeless Children)

Imprisoned in the Maximum security facility
Returning to her own TARDIS, the Doctor voiced her intention to return to Sheffield to pick up her friends, but, while she was collecting her thoughts, a "Judoon Cold Case Unit" appeared and teleported her to a Maximum security facility in space, (TV: The Timeless Children) where she was charged with evading the Judoon, and seven-thousand other offences, and sentenced to life imprisonment. (TV: Revolution of the Daleks)

Reunions and farewells
After "a tough few decades" in prison, the Doctor was rescued by Jack Harkness using a temporal-freezing gateway disinhibitor bubble, and they escaped back to the TARDIS using Jack's vortex manipulator, with the Doctor trying to return to Team TARDIS shortly after they returned to Sheffield, only to arrive ten months later instead. Despite some initial friction, they informed her of Jack Roberson being spotted with a Dalek, and the Doctor went to confront him with Graham and Ryan, while Jack and Yaz went to explore a factory in Osaka that had Dalek DNA traces detected in it. When Robertson denied knowledge of the Osaka facility, and insisted that he was only making security drones run by artificial intelligence, the Doctor brought him to the factory, which she learnt was a Dalek clone farm being run by a clone of the Reconnaissance Dalek, who transported the new mutants into the new casings, beginning a takeover of England.

Not able to think of a better plan, the Doctor discreetly lured in a Dalek Death Squad to deal with the Defence Drone Daleks, only for Robertson to join forces with them by informing them of the Doctor's presence after they had destroyed all the "impure" clones. To deal with the Death Squad, the Doctor sent Jack, Ryan and Graham aboard their ship to plant explosives, whilst she lured the Daleks into the spare TARDIS, which she programmed to fold in on itself and go into the Void, destroying the Daleks. Afterwards, Jack left to catch up with Gwen Cooper, and Ryan decided he wanted to stay in Sheffield, with Graham also deciding to remain with his grandson, leaving only Yaz to travel with the Doctor. Though saddened by their departures, the Doctor was happy for them and gifted them their own psychic papers. (TV: Revolution of the Daleks)

Whilst visiting the hanging gardens with Yaz, the Doctor went off to get them Kronkburgers, (WC: A Message from Yaz) but got distracted. (WC: A Message from the Doctor) She instead found herself in the British countryside during the 1860s, at the same time an anachronistic rocket was also present. (PROSE: La Boîte Bleue)

While outmaneovring a Balderian warfleet in the TARDIS, the Doctor discovered that Yaz had sent her a voice message and replied to it with her own voice message, apologising for her prolonged absence and promising to return to Yaz soon. (WC: A Message from the Doctor)

Death
According to one account, the Doctor regenerated into her successor while alone in her TARDIS. (PROSE: Contents)

Undated events

Alone
The Doctor became an undercover assassin that served the King, known as the "Masked Assassin". After some time, the King decided he wanted the Doctor herself dead, but she ran across the hills and took cover behind a Dalek, until the "Masked Assassin" was contracted to kill the Doctor. The Doctor managed to convince the people to revolt against the King and use democracy instead. After she emptied out his slave mines, the Doctor confronted the King and revealed she was his assassin. As the people approached with pitchforks, all the guards fled, and the Doctor suggested the King think about exile. (PROSE: The Death List)

The Doctor once posed as a museum curator in Venice. visited her to ask for the location of items that had been stolen from her in the 14th century, taking an old map from her and leaving, without realising that she had just spoken to the Doctor. Later, the Doctor saved Antonia from being left behind in 14th century Venice, returning her to the present. She left Antonia with a note chastising Missy for her actions and that she would have to "try harder next time". She then cleared out her office and told her assistant to tell anyone who asked, "the Doctor doesn't work here anymore." (PROSE: The Liar, the Glitch and the War Zone)

The Doctor once offered to babysit a young Judoon refugee from a "big fight" on a world far from Earth, but was prevented from doing so by other Judoon. She went to 1966 Dublin after the young Judoon landed there, but found it was already in the care of Patricia. After the Judoon returned to its people, the Doctor gave a few encouraging words to Patricia. (PROSE: The Rhino of Twenty-Three Strand Street)

Alternate timelines
In a potential future, the Doctor found herself trapped inside the Catastrophia. Due to the Catastrophia's warped temporal laws, the Doctor's timeline from here was split into two outcomes. In one timeline, the Doctor never escaped, and eventually lost her mind, becoming the Herald. In another, the Doctor took shelter inside the logic cube and became the Sanity. (COMIC: Herald of Madness, Mistress of Chaos)

In the aborted timeline, killed the Doctor by throwing her into the heart of a star, after she escaped from being shackled in its orbit. (AUDIO:  Masterful)

Personality
Influenced by the final words of the Twelfth Doctor, (TV: Twice Upon a Time) the Thirteenth Doctor was a kind-hearted individual, never refusing anyone help if they needed it, (TV: The Woman Who Fell to Earth) and willing to take great risks in protecting innocent lives. (TV: The Woman Who Fell to Earth, The Witchfinders, The Battle of Ranskoor Av Kolos) She was also highly secretive, failing to tell her companions about her past until pressed into doing so, (TV: Spyfall) and sometimes leaving them behind to deal with secret affairs. (TV: Fugitive of the Judoon) However, she would be upfront with her feelings when letting people know when she was afraid or no longer feeling a certain way, (TV: Demons of the Punjab, The Witchfinders, It Takes You Away, Resolution) unless it was a subject she was still adjusting too. (TV: Revolution of the Daleks)

She would keep her discoveries hidden from others with the mind-set of protecting them from a harmful realisation, (TV: It Takes You Away, Orphan 55) and was not above being cryptic, handing an annotated map of 14th century Venice without explaining it, and leaving Missy to discover for herself what the annotations meant, while also not divulging her true identity to Missy. (PROSE: The Liar, the Glitch and the War Zone)

The Thirteenth Doctor was a chatty individual, frequently rambling to distract herself or others from her worries, or to inspire hope in herself. (TV: Demons of the Punjab, Spyfall, The Timeless Children, Revolution of the Daleks) However, when facing an adversary by herself, the Doctor would appear as a confident and direct speaker, even acting in a passive aggressive manner to antagonising them into exposing their shortcomings. (TV: The Woman Who Fell to Earth, Rosa, The Witchfinders, Nikola Tesla's Night of Terror) She once admitted she could talk to herself without fear of isolation, believing that another person in a conversation would just "get in the way". (TV: Orphan 55)

Describing herself as "socially awkward", (TV: Can You Hear Me?) the Doctor could be blunt with those she spoke with, openly pointing out the ineffectiveness of others' aid, (TV: The Woman Who Fell to Earth, Spyfall) being clear with her feelings towards someone for their past actions, (TV: Resolution) voicing her frustrations when people in danger were unprepared for defensive combat, (TV: Ascension of the Cybermen) and calling Nikola Tesla a "big fat liar" after he tried to deceive her. (TV: Nikola Tesla's Night of Terror) When Graham opened up to her about his fears of his cancer returning, the Doctor openly stated her uncertainty on how to respond, instead electing to narrate her movements and admit she would later think of something she should have said to him. (TV: Can You Hear Me?)

Like previous incarnations, the Thirteenth Doctor enjoyed it when people underestimated her, deliberately using her awkwardness to make herself seem "smaller", but found it disappointing when people continued to dismiss her after she threw off the persona. (PROSE: The Shadow Passes)

A self-proclaimed "nutter", (TV: It Takes You Away) the Doctor had a ruthless side to her, leaving to the mercy of the Nazis when stealing his TARDIS, even deactivating his perception filter to expose his non-Aryan appearance to them, (TV: Spyfall) and reluctantly exposing Percy Shelley to his future death to trick the Cyberium into leaving his body. (TV: The Haunting of Villa Diodati) She also talked down to the Queen of the Skithra as a parasite who was only queen of "shreds and patches", and then threatened her legacy as being forgotten after she was "too stupid" to take "a chance to evolve". (TV: Nikola Tesla's Night of Terror) During the Dalek Drones' takeover of Earth, the Doctor quickly initiated the "nuclear option" of summoning the Death Squad Daleks to fight them. She was subsequently ruthless in destroying the Daleks she had summoned, even at the cost of a TARDIS. (TV: Revolution of the Daleks)

She also had a bit of an ego, stating her plans would be a success due to her "not [being] an amateur", (TV: The Woman Who Fell to Earth) boasting about her intelligence, (TV: The Ghost Monument, The Battle of Ranskoor Av Kolos) and describing her chapter in the Book of Celebrants as being "more of a volume". (TV: The Tsuranga Conundrum) She claimed to have an understanding of "pretty much everything", (COMIC: A New Beginning) and delighted in one Dalek's reaction to hearing her name. (TV: Resolution)

She also disliked not being in charge, still assuming to know better when someone else was better equipped to take charge in the situation at hand, (TV: The Tsuranga Conundrum, Kerblam!) believing her authority to be "mountainous". (TV: The Haunting of Villa Diodati) Even while trying to act incognito, the Doctor had no patience for others' claims of authority, and was especially protective of others who suffered under such leadership. Nevertheless, she saw fault not in the systems themselves, but in the actions of those individuals who sought to abuse them. (TV: Kerblam!)

She retained the absent-mindedness of her previous incarnation, tending to forget how many times she did something, (TV: Rosa) forgetting whether she was awarding points or gold stars to her companions, (TV: Demons of the Punjab) and only remembering she was holding an item of interest after asking for its whereabouts in a state of a panic. (TV: Spyfall) She had a self-admitted tendency to confuse "meaning to say something" with "actually saying it". (TV: Praxeus) She could even fail to notice her companions' presence or absence, even when they had been missing for some time. (TV: Fugitive of the Judoon, Can You Hear Me?)

She also retained her predecessor's veneration of the dead. (TV: Demons of the Punjab) As a result, the Doctor held respect for all living beings even if they caused harm due to their nature, (TV: Arachnids in the UK, The Tsuranga Conundrum) and sought to give a second chance even to the deadliest of her foes, (TV: Resolution) but would offer no second chances to those that truly irked her. (TV: Nikola Tesla's Night of Terror)

Upon seeing Gallifrey in ruin, the Doctor reacted with devastation. After discovering was responsible for the act in retaliation for "the lie of the Timeless Child", the Doctor was left in a foul mood, (TV: Spyfall) that lasted for some time. (TV: Orphan 55) Even after some time had passed, the Doctor was still sore on the subject of dead planets. (TV: Nikola Tesla's Night of Terror) She would occasionally revisit Gallifrey after it was ravaged by. (TV: Fugitive of the Judoon) After the Master revealed that she was the Timeless Child of legend, and the Time Lords had redacted her memories of that time of her life, the Doctor had a brief identity crisis, until a conversation with a past incarnation in the Matrix convinced her that, rather than being reduced to less, she "contain[ed] multitudes more than she ever thought". (TV: The Timeless Children) However, even after having "decades" in prison to dwell on her discovery, she admitted to Ryan that she was continuing to struggle with who she really was. (TV: Revolution of the Daleks)

She once noted that when working on something, she liked to lay out all she needed on a table in front of her, allowing her to have a complete view of the task at hand. (PROSE: TARDIS Tour)

The Doctor enjoyed biscuits, (TV: Demons of the Punjab) with custard creams being a particular favourite, (TV: The Ghost Monument) and tea, (TV: Arachnids in the UK) with Yorkshire Tea being her preference. (PROSE: The Good Doctor) For breakfast, she liked to have cereal or croissants, (TV: Arachnids in the UK) and enjoyed fried egg sandwiches. (TV: The Woman Who Fell to Earth) However, she disliked bourbon biscuits. (PROSE: Chasing the Dawn)

She also liked holograms, "big locked doors", (TV: The Ghost Monument) the number 51, the musical Hamilton, (TV: The Tsuranga Conundrum) apple bobbing, (TV: The Witchfinders) Wellington boots, (TV: The Battle of Ranskoor Av Kolos) "pretty" landscapes, running, (COMIC: Hidden Human History) and laminators. (TV: Spyfall) She retained her eleventh incarnation's fondness for fezzes, (TV: Kerblam!) enjoyed wearing plumed headgear, (TV: The Haunting of Villa Diodati) and admired Ryan for how well he looked in a beanie hat. (TV: ''Revolution of the Daleks')

The Doctor held a great admiration for those who crafted things for themselves and made their own inventions, praising both Ada Lovelace and Nikola Tesla for their ingenuity and forward thinking. Placing intrinsic value in the creation of novelty, she saw the lack of recognition each received as trivial in comparison to their accomplishments. (TV: Spyfall, Nikola Tesla's Night of Terror) She also admired Amelia Earhart for taking the world on and pushing it forward. (PROSE: Chasing the Dawn) In contrast, she admonished those who only took power and recognition through ownership alone. She claimed that such people, who never created things themselves, were destined to be forgotten to history. (TV: Nikola Tesla's Night of Terror)

While she once claimed to "love a conspiracy", (TV: Arachnids in the UK) she disliked ones that resulted in information being purposely withheld from her. (TV: Kerblam!) She also heavily disliked having empty pockets, (TV: The Woman Who Fell to Earth) as well as olives, (PROSE: The Good Doctor) bullies, and people in danger. (TV: Kerblam!) She also did not enjoy physical contact with others, (TV: Orphan 55, The Timeless Children) reacting awkwardly when hugging Najia Khan, (TV: Arachnids in the UK) but made an exception for dear friends. (TV: ''Revolution of the Daleks')

The Thirteenth Doctor stated that love was central to her "faith", believing it to be the better source of belief. (TV: Demons of the Punjab, The Witchfinders) She was also a strong believer in hope, (TV: The Tsuranga Conundrum, The Battle of Ranskoor Av Kolos) and once voiced the opinion that "where there [was] risk, there [was] hope." (TV: Spyfall) She claimed to Jack Robertson that hate would only spread if not stopped. (TV: Revolution of the Daleks)

Like her early incarnations, the Thirteenth Doctor was not interested in romance, (TV: Arachnids in the UK) but retained a respect for it, (TV: Demons of the Punjab) even describing herself as a "romantic", (TV: Praxeus) though she disliked being flirted with. (TV: The Haunting of Villa Diodati) She stood against racism and prejudice, and showed her disgust with gentle comments of acceptance. (TV: Rosa)

The Doctor claimed that she enjoyed making "trip[s] into the past" for research purposes, but knew to be cautious when making such trips, even writing a note to chastise for her lack of caution in that regard. (PROSE: The Liar, the Glitch and the War Zone) She took her devotion to the preservation of history so seriously that she described herself and her companions as its "guardians". (TV: Rosa) Despite her usual unwillingness to tamper with time, the Doctor found herself willing take her companions to visit their own family history, with some persuasion, though warned her friends to "tread softly" on their own history. (TV: Demons of the Punjab) At times, the Doctor's sense of justice got the better of her, making her intervene in past events if she believed them to be minuscule enough to not impact history in too great a detail. (TV: The Witchfinders) She would still show signs of distress if preserving history meant letting injustices stand and go unpunished. (TV: Rosa, Demons of the Punjab) After Graham and Ryan left, the Doctor briefly contemplated travelling back in time to get more time with them, but did not act on the idea. (TV: Revolution of the Daleks)

Similar to the Tenth Doctor, the Thirteenth Doctor disliked weaponry, opting instead to use her intellect and environment to her advantage, (TV: The Ghost Monument, Arachnids in the UK) even voicing her disapproval when someone resorted to using a weapon, (TV: Spyfall) though she admitted this was a "flexible creed", as anything that could be rebuilt was "fair game" to be destroyed. (TV: The Battle of Ranskoor Av Kolos) Specifically, the Doctor believed guns "made things worse", as they only agitated attackers, (TV: The Ghost Monument) and that only "idiots" carried knives. (TV: The Woman Who Fell to Earth) Nevertheless, even after Leon Perkins threatened her with a gun, the Doctor favoured serving him tea over imprisoning him, hoping to come to a common understanding with him. (COMIC: A New Beginning)

Furthermore, the Thirteenth Doctor was passionately against murder, always trying her best to subdue her opponents in a non-lethal fashion, (TV: Arachnids in the UK, The Witchfinders, The Battle of Ranskoor Av Kolos) and was particularly outraged when she saw someone kill when there was no need too. (TV: Revolution of the Daleks) She also expressed distaste for the act even when committed by her allies, (TV: The Woman Who Fell to Earth, The Battle of Ranskoor Av Kolos, Fugitive of the Judoon) and was deeply disturbed when she was forced to indirectly be responsible for the loss of life, (TV: Kerblam!) seeking confirmation from her friends that she had given every opportunity for a better outcome when she resorted to killing her foes. (TV: Resolution) While she was prepared to unleash the death particle on Gallifrey to stop and the CyberMasters, she was ultimately unable to detonate the device. (TV: The Timeless Children) However, when facing opponents that posed a great threat to innocent lives, the Doctor was more willing to lead them to their deaths. (TV: ''Revolution of the Daleks')

When her patience and rage reached their zenith, the Doctor would resort to psychically attacking the one she was enraged with. (TV: The Timeless Children)

She implored those around her to ask questions about a situation, and showed no irritation on how off topic the questions got, (TV: The Woman Who Fell to Earth) even showing excitement when the right questions were asked, (TV: Rosa) but would clarify when "the wrong question" to a situation was being posed. (TV: Arachnids in the UK) However, she showed displeasure in handling multiple questions simultaneously, (TV: The Woman Who Fell to Earth) and would refuse to answer questions asked of her if the person did not answer any questions she asked first. (TV: The Battle of Ranskoor Av Kolos) She also excused her solo trips to the destroyed Gallifrey by claiming that Team TARDIS "ask[ed] too many questions" about her private affairs. (TV: Fugitive of the Judoon)

Much like her eleventh incarnation, the Thirteenth Doctor would run into a situation without a strategy in mind, hoping to come up with a plan in the heat of the moment, (TV: The Woman Who Fell to Earth, Resolution, Revolution of the Daleks') claiming to be "good in a tight spot" (TV: The Ghost Monument) and to enjoy throwing a "curveball" into the situation, (TV: Fugitive of the Judoon'') but would take precautions when she knew how dangerous a situation was. (TV: The Battle of Ranskoor Av Kolos, Ascension of the Cybermen) She was confident she could take on any threat. (TV: Resolution)

Claiming to have "never been a fan of growing up", (TV: Fugitive of the Judoon) the Doctor used humour to defuse tension, (TV: The Tsuranga Conundrum) demonstrating a playful sense of humour. She labelled the Moment's interface "a Christmas cracker", and responded to Cass Fermazzi's mention of having needed childhood therapy with a dry "didn't we all". (PROSE: The Day of the Doctor)

She retained the guilt demonstrated in her prior incarnations over the events of the Last Great Time War. Visiting Cass prior to her death, the Doctor expressed her regret over Cass' fate and noted that saving Cass was impossible as "[Cass] was too wrapped up in [her] timeline", demonstrating her continued respect for the Laws of Time. (PROSE: The Day of the Doctor) Like her immediate predecessor, she believed that "no one ever wins at war". (PROSE: The Good Doctor)

She was particularly displeased to be reminded of being an outcast, (TV: The Ghost Monument) and tried to hide her fear of loneliness with the company she kept, becoming upset at the prospect of bidding her companions a farewell, (TV: The Woman Who Fell to Earth, Arachnids in the UK) even skipping ahead to their next rendezvous times when Team TARDIS took their breaks from the TARDIS. (TV: Can You Hear Me?) She considered her friends to be an extended family, (TV: Resolution) and emphasised with Nikola Tesla for feeling "out of place" amongst other people. (TV: Nikola Tesla's Night of Terror)

The Thirteenth Doctor enjoyed the company of the Seventh Doctor, even singling him out as "on [her] team" during a Multi-Doctor Event. She also teasingly invited herself to the "wedding" of her bickering second and third incarnations. She affectionately called all of her previous selves her "fam". (WC: Doctors Assemble!)

The Thirteenth Doctor was quick to make new friends, (TV: The Woman Who Fell to Earth, Resolution, Can You Hear Me?) and generally accepted them without question. (COMIC: A New Beginning) She also had a much friendlier approach to Santa Claus than her immediate predecessor, even allowing him to borrow her TARDIS for an emergency, (WC:  'Twas the Night Before Christmas) in spite of her dislike of being separated from her ship. (TV: The Tsuranga Conundrum)

The Doctor considered Graham O'Brien, Yasmin Khan and Ryan Sinclair to be her "best friends". (TV: Resolution) She was encouraging with them, especially when they made a connection or deduction, showed prowess, acted well in a crisis, or came up with a good plan of action. (TV: Arachnids in the UK, The Tsuranga Conundrum, Demons of the Punjab, Resolution, Praxeus) Nevertheless, when one of her friends had a "bad idea", she did not shy away from saying so. (COMIC: A New Beginning) She was stern with Graham when he expressed an intention to kill Tzim-Sha, warning him he would not be invited back into the TARDIS if he carried it through, and expressed her pride in him when he chose not to kill Tzim-Sha. (TV: The Battle of Ranskoor Av Kolos) She would also get agitated with them when she was in a poor mood, (TV: Orphan 55, Ascension of the Cybermen) and was slightly mift when Ryan suggested that being away from the TARDIS had been good for him. (TV:Revolution of the Daleks)

She always gave her friends the chance to walk away or stay behind when faced with danger, (TV: Rosa, Arachnids in the UK, Resolution, The Haunting of Villa Diodati) or would order them to retreat if the dangers proved too severe, (TV: Ascension of the Cybermen) and sometimes preferred to face an enemy alone. (TV: Rosa, Demons of the Punjab, The Battle of Ranskoor Av Kolos, Resolution, The Haunting of Villa Diodati)

According to Graham O'Brien, when reflecting on her attitude after seeing a ravaged Gallifrey, "one minute [she was] all smiles, [and the] next minute [her] mind [was] somewhere else", but he still believed that the Thirteenth Doctor was "the best person [he] [knew]". (TV: Fugitive of the Judoon)

Habits and quirks
Soon after her regeneration, the Thirteenth Doctor had some trouble adjusting to perceptions around her new gender, (TV: The Woman Who Fell to Earth, The Ghost Monument, Spyfall) taking some time to get used to people calling her "Ma'am" and "Madam". (TV: The Woman Who Fell to Earth, Rosa) While she would become frustrated when facing judgement because of her new form, (TV: The Witchfinders) she saw advantages in "[looking] like a girl" in interactions with others, (PROSE: Chasing the Dawn) and openly enjoyed getting opportunities she never had when she used to be a man. (TV: Demons of the Punjab) The Doctor would occasionally slip up when referring to herself, forgetting to account for the change in her identity, (TV: The Ghost Monument, Spyfall) as, much like the Eighth Doctor, she did not consider herself to be a man or a woman, "in the way that [humans] understand" such things. (PROSE: The Good Doctor)

Like her ninth incarnation, the Thirteenth Doctor spoke with a northern accent. She also used "Oi" to get someone's attention, (TV: The Woman Who Fell to Earth, Rosa, The Battle of Ranskoor Av Kolos, Orphan 55) when beginning a counter-argument, (TV: The Tsuranga Conundrum, Demons of the Punjab) or when she felt insulted. (TV: Can You Hear Me?)

Similar to her tenth incarnation, she would consider good things and ideas to be "brilliant", (TV: Twice Upon a Time, Rosa, Kerblam!, The Witchfinders, It Takes You Away) but would also use the word in a sarcastic sense, (TV: The Ghost Monument) and to describe how someone performed in a crisis, (TV: The Tsuranga Conundrum, Orphan 55) or when describing a person in general. (TV: Spyfall, Praxeus)

Also like the Tenth Doctor, she was quick to apologise for her own actions and others' circumstances. (TV: The Woman Who Fell to Earth, The Ghost Monument, Arachnids in the UK, The Tsuranga Conundrum, Demons of the Punjab, The Witchfinders, It Takes You Away, The Battle of Ranskoor Av Kolos, Resolution, Spyfall, Orphan 55, Can You Hear Me?, The Haunting of Villa Diodati)

When the Doctor came to a new realisation, or was informed of something, she would utter, "oh.", as the information dawned on her. (TV: The Ghost Monument, Rosa, Arachnids in the UK, Demons of the Punjab, Resolution, Spyfall, Praxeus, Can You Hear Me?, The Timeless Children)

The Doctor would state a feeling she was having, but then backtrack on that feeling and claim to be feeling the opposite of what she initially felt. (TV: The Woman Who Fell to Earth) She would also state one thing before backtracking to elaborate on her statement. (TV: The Ghost Monument, Kerblam!, Orphan 55, Can You Hear Me?, Revolution of the Daleks)

She was known for giving speeches to her friends that had an educational quality to them, (TV: Rosa, The Battle of Ranskoor Av Kolos, Orphan 55, Nikola Tesla's Night of Terror) and for referring to others by a title or codename. (TV: Arachnids in the UK, Resolution, Spyfall)

She often boasted about meeting historical figures, usually with an accompanying tale that shed new light on the character of said figure, (TV: The Ghost Monument, Rosa, Arachnids in the UK, Demons of the Punjab, Kerblam!, The Witchfinders) to the point that Yaz affectionately called her a "tragic name-dropper". (COMIC: The White Dragon)

When surprised, the Doctor tended to give a yelp. (TV: The Ghost Monument, The Tsuranga Conundrum, Kerblam!, Resolution, Spyfall, Ascension of the Cybermen)

When making a statement, the Doctor would say "right" before elaborating on her statement. (TV: The Woman Who Fell to Earth, It Takes You Away)

When speaking in absolutes, she tended to describe a development, or even a person, with "total". (TV: Nikola Tesla's Night of Terror, Fugitive of the Judoon)

She would say things were going to be "fine" to reassure people, or when describing an ongoing situation, usually when all evidence pointed to the contrary. (TV: The Woman Who Fell to Earth, The Ghost Monument, Orphan 55)

When pressing someone to move or act quickly, she would say "chop-chop", (TV: The Woman Who Fell to Earth, Kerblam!) or, "get a shift on". (TV: The Ghost Monument, The Tsuranga Conundrum; COMIC: Mistress of Chaos)

When explaining her intended actions, the Doctor would utter, "but not right now", to show that she was preoccupied with a different situation than the one she was explaining. (TV: The Ghost Monument, The Tsuranga Conundrum)

The Thirteenth Doctor would lean her face forward, with her eyebrows lowered and her upper lip stretched upwards, when she was feeling annoyed, (TV: The Woman Who Fell to Earth, Demons of the Punjab) giving an unbelievable explanation, (TV: The Ghost Monument) when thinking intensely, (TV: Arachnids in the UK, The Tsuranga Conundrum, Resolution) when deliberately antagonising an opponent, (TV: The Haunting of Villa Diodati) and feeling enraged. (TV: The Timeless Children)

She would likewise scrunch her face up when annoyed, (TV: Rosa, The Witchfinders, Revolution of the Daleks) trying to hide her hurt feelings, (TV: Arachnids in the UK) in pain, (TV: Demons of the Punjab) observing, (TV: It Takes You Away, Resolution) apologising for an embarrassing stunt she pulled, (TV: Resolution) enquiring from a distance, (TV: Orphan 55) shocked by an unforeseen action, (TV: Praxeus) or disgusted. (TV: Can You Hear Me?)

When pleased, the Doctor would beam a wide smile. (TV: The Woman Who Fell to Earth, The Ghost Monument, Arachnids in the UK, Demons of the Punjab, Resolution, Orphan 55, Nikola Tesla's Night of Terror)

When taking enjoyment in her adversaries' downfall, she would wear a mocking grin, (TV: Spyfall, Can You Hear Me?) and would sometimes flick a half-smile. (TV: The Woman Who Fell to Earth, Arachnids in the UK, The Tsuranga Conundrum, Demons of the Punjab, The Battle of Ranskoor Av Kolos, Resolution, The Haunting of Villa Diodati, Revolution of the Daleks)

She often stood with her hands on her hips, (TV: The Ghost Monument, Rosa, Arachnids in the UK, The Tsuranga Conundrum, Kerblam!, Resolution, Spyfall, Nikola Tesla's Night of Terror, Praxeus, Can You Hear Me?, The Haunting of Villa Diodati, Revolution of the Daleks) or behind her back. (TV: The Tsuranga Conundrum, Kerblam!, The Witchfinders, Nikola Tesla's Night of Terror, The Haunting of Villa Diodati)

As with previous incarnations, she would also stand with her hands in her pockets, flicking her coat back as she did so. (TV: Demons of the Punjab, It Takes You Away, Spyfall)

When giving a speech, proclaiming instructions, or vocally analysing her situation, the Doctor would move her hands upwards, with her hands facing her head and with her fingers curled. (TV: The Woman Who Fell to Earth, The Ghost Monument, The Tsuranga Conundrum, Kerblam!, The Witchfinders, It Takes You Away, Resolution, Spyfall, Nikola Tesla's Night of Terror, Praxeus, The Haunting of Villa Diodati)

When drawing it from her coat, she would flourish her sonic screwdriver. (TV: The Woman Who Fell to Earth, The Ghost Monument, Arachnids in the UK, Kerblam!, Resolution, Spyfall, Orphan 55, The Haunting of Villa Diodati, The Timeless Children)

After witnessing or learning of something that unnerved her, the Doctor would stare into the distance while remaining silent and unresponsive to her surroundings. (TV: Demons of the Punjab, Spyfall, Fugitive of the Judoon, The Timeless Children, Revolution of the Daleks)

The Thirteenth Doctor had a tendency to make immediate assumptions, sometimes only to discover that her judgements were misplaced, though she would own up to her mistakes, once pointed out to her. (TV: The Woman Who Fell to Earth, Demons of the Punjab, Kerblam!, Can You Hear Me?)

The Doctor used a point system to grade her companions to mark how well they performed. She alternated between giving out points and gold stars, (TV: The Tsuranga Conundrum, Demons of the Punjab, It Takes You Away, Praxeus, Revolution of the Daleks) as she could not remember which she had initially decided upon. (TV: Demons of the Punjab)

Skills
The Thirteenth Doctor demonstrated astute detective skills, (TV: The Woman Who Fell to Earth, Arachnids in the UK, It Takes You Away) and could deduce a person's thought pattern through eye contact. (TV: The Woman Who Fell to Earth, The Battle of Ranskoor Av Kolos) She was also able to tell when she was talking to a bad liar, (TV: Rosa, The Tsuranga Conundrum) unearth a truth by studying someone's facial reaction, (TV: Orphan 55) and, occasionally, tell when someone was attempting to deceive her. (TV: Nikola Tesla's Night of Terror) Likewise, she was an effective liar herself, able to trick an entire fleet of Daleks that she was piloting her TARDIS for them to ambush her, only to reveal as she trapped them that it was set to take them to the Void to destroy them. (TV: Revolution of the Daleks)

With the aid of Venusian aikido, the Doctor could use her pinkie finger to paralyse someone without harming them by pressing on their throat, (TV: The Ghost Monument, Kerblam!) and could throw someone over her shoulder with little difficulty. She was also swift and nimble, able to avoid being struck by a fist with ease, (COMIC: The Warmonger) and glide across a surface, jump and roll while avoiding shots from a Dalek gunstick. (TV: Resolution)

By placing her hand on someone's temple, the Doctor could erase their memories, (TV: Spyfall) or search through their memories to find information. (TV: Orphan 55, The Haunting of Villa Diodati) In extreme cases, the Doctor was capable of telepathically inducing a state of death into someone by showing them how they were destined to die and making their bodies believe the illusion. (TV: The Haunting of Villa Diodati) When another Time Lord was close enough, the Doctor could engage them in telepathic contact from some distance away. (TV: Spyfall, The Timeless Children)

Having a speciality for "high-speed inventing", the Thirteenth Doctor was a skilled mechanic and engineer, (TV: Nikola Tesla's Night of Terror) able to craft new contraptions from whatever was at hand, often ordinary raw materials, (TV: The Woman Who Fell to Earth, Demons of the Punjab) or, at any given moment, to alter and adapt technology already at her disposal to meet various needs. (TV: The Woman Who Fell to Earth, Demons of the Punjab, The Battle of Ranskoor Av Kolos) Though she favoured elegance in technology, (TV: Nikola Tesla's Night of Terror) the Doctor had little trouble working with more unorganised complexity, even when, to her frustration, some layers "[made] no sense". (TV: The Woman Who Fell to Earth)

She was able to quickly reformat Ryan's mobile phone into a tracker to find the gathering coil, (TV: The Woman Who Fell to Earth) reactivate Twirly to be plugged into the Kerb!am System, (TV: Kerblam!) rewired several settings on the TARDIS by adjusting the setting externally, (TV: Spyfall) and was capable of "hot-wiring" warp drives. (TV: Ascension of the Cybermen)

She was also equally adept at scientific analysis, able to determine a substance's component ingredients and even calculate proportions using only a microscope. When the sonic screwdriver offered no help, the Doctor was known to go "analogue". On one occasion, she constructed a makeshift chemistry set out of oil, water, tree bark, a saucepan, nine containers, an old newspaper, a touch of ox spit and a chicken poo, which she then used to analyse a Thijarian remnant sample. (TV: Demons of the Punjab)

She was able to analyse her environment by tasting the ground, (TV: It Takes You Away) and could determine her location in time and space by observing the smells of her surroundings. (TV: Spyfall) She claimed also to be able to smell the effects of time travel on those who had been through the Time Vortex, though she noted that this was an oversimplification. (COMIC: A New Beginning) As with her previous incarnations, the Thirteenth Doctor could analyse an object by taste. (TV: The Haunting of Villa Diodati)

When in control of her TARDIS, the Doctor was able to piloting the ship around Jake Willis and save him before Suki Cheng's ship exploded with him still onboard. (TV: Praxeus)

She was also a competent driver of motor vehicles, able to drive both cars and motorbikes in high-stress situations. (TV: Spyfall)

Without the aid of a translation circuit, the Doctor could read the language of the Creators of Death. (TV: The Ghost Monument) The Doctor also showed the ability to speak English without its aid, furthering showing her multilingualism. (TV: The Woman Who Fell to Earth, The Ghost Monument) She could also decode steganography images. (TV: Spyfall)

She could quickly calculate the length of time it would take her to do something, and act with quick succession, (COMIC: The Warmonger) though she sometimes doubted she would be able to complete the task in time. (TV: Resolution)

Like her predecessors, the Thirteenth Doctor was a skilled escape artist, crediting it to the teachings of Harry Houdini. (TV: The Witchfinders)

Possessing a photographic memory, she was able to recite the entirety of Harry Potter and the Philosopher's Stone from memory. (TV: Revolution of the Daleks)

Appearance
The Thirteenth Doctor resembled a woman in her mid-thirties, possessing jaw-length blonde hair with dark roots, and hazel-coloured eyes. (TV: Twice Upon a Time) To her annoyance, she was shorter than in her previous incarnation, (TV: The Woman Who Fell to Earth) and disliked being referred to as "small". (TV: Fugitive of the Judoon)

During her time imprisoned in the maximum security facility, the Doctor's hair grew out to shoulder-length. (TV: Revolution of the Daleks)

In preparation for Umbreen's wedding to Prem, the Doctor had henna tattoos temporarily applied to her arms by Hasna. She also had a flower tucked behind her left ear during the ceremony. (TV: Demons of the Punjab)

Immediately after regenerating, the Thirteenth Doctor viewed her reflection and deemed her new face to be "brilliant", (TV: Twice Upon a Time) though she was oblivious to the fact that she had changed from male to female until informed by Yasmin Khan. (TV: The Woman Who Fell to Earth)

Patricia thought that the Doctor's face conveyed a constant, unashamed amazement, (PROSE: The Rhino of Twenty-Three Strand Street) and Lee Clayton noted the intelligence conveyed in her eyes. (TV: Fugitive of the Judoon) The Corsair also voiced her approval upon meeting the thirteenth incarnation, (COMIC: Old Friends) with James I commenting on her "alluring form". (TV: The Witchfinders)

Main attires


After going clothes shopping at a charity shop with Ryan Sinclair and Yasmin Khan, (TV: The Woman Who Fell to Earth) the Thirteenth Doctor took to wearing a hooded, lilac-blue trench coat with midnight blue interim, (COMIC: The Many Lives of Doctor Who) apart from the sleeves, which had lavender pink insides, and a rainbow pattern along the edges. (TV: The Woman Who Fell to Earth) She was very fond of her coat, (TV: The Battle of Ranskoor Av Kolos) and would try to avoid damaging it, (TV: The Witchfinders) though she had to rip part of it to help history go undisturbed from Krasko's meddling, but had the tear repaired by seamstress Rosa Parks. (TV: Rosa)

Under her coat, the Doctor wore a variety of similarly designed t-shirts with rainbow stripes running across their chest, such as a low collar navy blue shirt, (TV: The Woman Who Fell to Earth) a dark pink low collar shirt, (TV: Rosa) a dark pink crew collar shirt, (TV: The Tsuranga Conundrum) a navy blue crew collar t-shirt with a smeared rainbow pattern, (TV: Kerblam!) light blue crew collar shirt, (TV: Resolution) and a dark purple crew collar shirt. (TV: Revolution of the Daleks) Under her shirt, she wore a white, long-sleeved undershirt. (TV: The Woman Who Fell to Earth, Rosa) On occasion, she would disperse with the t-shirt entirely and instead wear a navy blue jumper, (TV: Spyfall) a cobalt blue jumper, (TV: Orphan 55) or a blue, buttoned-up, sleeveless waistcoat with lapels and a clock pattern. (TV: The Haunting of Villa Diodati)

On her legs, she wore a pair of high-waisted teal blue capri trousers, (COMIC: The Many Lives of Doctor Who) kept up by mustard yellow braces. (PROSE: Rose; TV: The Woman Who Fell to Earth) For footwear, she wore blue, striped socks with brown, laced-up boots. (COMIC: The Many Lives of Doctor Who)

She also wore golden-ringed ear cuffs at the top and at the lobe of her left ear. The top cuff was a series of eight joint stars, and the bottom cuff was in the shape of two hands holding each other. (TV: The Woman Who Fell to Earth)

When performing maintenance on her TARDIS, or building a new device, the Doctor would wear a pair of protective goggles, (TV: The Woman Who Fell to Earth, Spyfall, Nikola Tesla's Night of Terror) and, similar to her fourth incarnation, she occasionally wore a scarf around her neck, with either a full rainbow pattern or a navy blue scarf with a rainbow pastern on the ends. (TV: Resolution, The Haunting of Villa Diodati)

She sometimes wore a navy blue bum bag around her waist to carry her sonic screwdriver and psychic paper. (TV: Arachnids in the UK) At some point, she owned a handbag. By the end of her life, it was stored in a chest containing items belonging to her previous twelve incarnations. (PROSE: Contents)

Other clothes
The Thirteenth Doctor had a liking for headgear, and would wear a hat of some kind at the first opportunity. (TV: Kerblam!, The Witchfinders, The Haunting of Villa Diodati)

During her brief employment as a packer at Kerb!am, the Doctor wore the standard purple vest for packers over her jacket. (TV: Kerblam!)

When gatecrashing Daniel Barton's casino themed party, the Doctor wore a white shirt with a black bow tie with golden dots, black capri trousers, black braces, black boots and socks, and a long black moleskin overcoat. (TV: Spyfall)

While masquerading as the "Masked Assassin", the Doctor hid her face behind a mask with a question mark on it and wore stilettos, with a cloak that spelled the number "13". (PROSE: The Death List)

The first female Doctor
The Thirteenth Doctor was the first official incarnation of the Doctor in the programme's history to be played by a woman, though the idea of a woman Doctor had been explored as early as 1980, when Tom Baker exited the role of the Fourth Doctor, and told the press, "I certainly wish my successor luck, whoever he—or she—might be." When Peter Davison decided to retire from the role of the Fifth Doctor, John Nathan-Turner told the Daily Star that "the hunt for a new Doctor starts today and it's quite feasible it will be a woman".

Second Doctor actor Patrick Troughton was quoted in 1983 as approving of the idea of a woman playing the Doctor. In 1986, series creator Sydney Newman suggested that "at a later stage Doctor Who should be metamorphosed into a woman", offering Joanna Lumley as the potential candidate for the Seventh Doctor, with and Dawn French also being mentioned. Lumley would ultimately portray a Thirteenth Doctor in the 1999 Comic Relief special The Curse of Fatal Death.

The 1999 BBC Eighth Doctor Adventures novel Interference: The Hour of the Geek was the first time it was commented on Time Lords switching genders during a regeneration, with I.M. Foreman twice stating to have had a female tenth incarnation. The 2002 Big Finish audio Seasons of Fear had the Eighth Doctor allude to the possibility of regenerating into a woman while in discussion with Sebastian Grayle, telling Grayle he was "not a glamorous woman at the moment".

The 2003 Big Finish Doctor Who Unbound story Exile starred another female Doctor, played by Arabella Weir. In the context of the story, which was set in another universe, it was established that suicide was necessary for a "sex-change regeneration", which was also considered a crime by the Time Lords. This suggestion garnered much criticism, and was not picked up by any following story.

While discussing casting for the 2005 continuation, Jane Tranter wanted the Ninth Doctor to be the first female incarnation, played by. A cut line in The Unquiet Dead would have had Sneed remark to the Ninth Doctor, "I thought you'd be a woman", to which the Doctor would respond, "No, not yet."

When David Tennant first announced his intention to leave the role of the Tenth Doctor in 2007, the UK Resource Centre for Women in Science, Engineering and Technology wanted the Eleventh Doctor to be female. When the Eleventh Doctor, played by Matt Smith, made his first appearance in 2010's The End of Time, he briefly thought he had regenerated into a woman after examining his long hair, but quickly realised his mistake on finding his Adam's apple.

2011's The Doctor's Wife was the first television story to make direct reference to a Time Lord changing gender through regeneration, with the Doctor talking about the Corsair. 2014 saw Steven Moffat introduce audiences to, who was revealed to be the first female incarnation of the Master in Dark Water, marking the first time an already established character had changed genders after regenerating. However, it was not until 2015 that audiences directly experienced such a regeneration, first in the Big Finish audio story The Black Hole with Pavo, and then in television story Hell Bent when the General regenerated.

In 2019, two years after the announcement of Whittaker's casting, Christopher Eccleston, speaking at Rose City Comic Con, said that the Ninth Doctor should have been female, and even claimed that Rose Tyler-actress Billie Piper should have been the Doctor instead of him, stating that "It's ridiculous we weren't thinking of a female Doctor at that time. In 2004, in me they picked yet another white skinny male to be the Doctor".

In 2020's Fugitive of the Judoon, Jo Martin was introduced as an unknown incarnation, with The Timeless Children establishing that the Doctor had, in fact, lived through multiple incarnations before the First Doctor. Of these forgotten incarnations, of which Martin's is suggested to have been one, at least four were female, including the earliest known incarnation, cementing that the Thirteenth Doctor had not, in fact, been the first female Doctor chronologically.

Appearances prior to her first full story
The Thirteenth Doctor is unique amongst her previous incarnations by having appeared multiple times in the official expanded media before her television debut in The Woman Who Fell to Earth, a fact that is acknowledged in the reference book Sheffield Steel: Essays on the Thirteenth Doctor by Sam Maleski.
