Dynamic, curious, and endlessly caring, the Thirteenth Doctor was the result of her predecessor's last stand for kindness. This incarnation of the Doctor believed in hope and practiced 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 she dubbed Tim Shaw that resulted in Grace's death, the Doctor inadvertently brought Graham, Ryan and Yaz with her in her search for the TARDIS.

After finding the TARDIS, the Doctor initially planned to take the trio back home, making several accidental trips along the way. After briefly returning to Sheffield, they officially joined the Doctor in her travels and 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, Captain 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, prior to her supposed first incarnation.

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, 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 Defence Drones and Death Squad Daleks, Ryan and Graham chose to resume their lives on Earth while the Doctor continued her adventures with Yaz.

Biography

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 Rassilon 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)

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 the Master and Missy 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

Thirteen Regeneration - The Many Lives of Doctor Who.jpg
The Thirteenth Doctor nears the end of her regeneration. (COMIC: The Many Lives of Doctor Who)
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) their first human friends, Ian and Barbara, (COMIC: The Path of Skulls) the strangeness of some of their adventures, (COMIC: Card Conundrum) their love for London and how the Third Doctor and Sarah Jane saved the city from the Dahensa; (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, including V. M. McCrimmon and Grandfather Halfling in the City of the Saved, as a "hello to the world". (PROSE: Postscript) The "Katy Manning" Iris also displayed knowledge that her "old friend in his blue box" was now not a bloke. (AUDIO: Iris Wildthyme Speaks...!)

As she continued the recollections, the Doctor settled into a new body. (COMIC: The Many Lives of Doctor Who) She 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?) River Song, (COMIC: Without A Paddle) and the Daleks. (COMIC: Harvest of the Daleks)

Post-regeneration

ThirteenMakesSonic.jpg
The Doctor makes her new sonic screwdriver. (TV: The Woman Who Fell to Earth)
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. Waking up in Graham and Grace's house, the Doctor found that she and her new friends had had DNA bombs implanted in them, and she tracked the signal to a Stenza transport pod before confronting the Stenza warrior, Tzim-Sha, who had arrived in Sheffield to hunt Karl as a rite of passage. 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, but Grace was killed while trying to overload the coil creature. After Grace's funeral, the Doctor went to a charity store with Ryan and Yaz and chose a new outfit before rigging up Tzim-Sha's transport pod to find 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)

The Doctor uncovered a sabotaged science experiment conducted by a 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. 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 it was revealed that Rosa had been exposed to artron energy, and with 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 the boycott in the hope that doing so would prevent equality, but he could not harm anyone due to a neural restrictor in his brain. Outdoing Krasko, the Doctor and friends were able to keep history on track, albeit by becoming part of the events, and ensured 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 family, and in doing so, found that their neighbour had been killed by a giant spider. When Graham arrived claiming to have found another giant spider in his house, the Doctor found that a Robertson Luxury Hotels hotel was at the epicentre of the spider sightings due to it being built on an old mine filled with waste disposed by Jack Robertson's disposal company that caused them to mutate. The group trapped the brood of spiders in Robertson's panic room, though Robertson killed the spider mother even though it was already dying. Later that night, Yaz, Ryan and Graham chose to continue travelling in the TARDIS; the trio accepted the risks, pulling the dematerialisation lever together to continue their journeys as Team TARDIS. (TV: Arachnids in the UK)

Early travels with 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)

13 meets Elizabeth II.jpg
Eva De Ville watches the Doctor run towards Elizabeth II. (COMIC: Where's the Doctor?)
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 brought them on board for treatment. However, 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, 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 into space. (TV: The Tsuranga Conundrum)

Wedding Punjab.jpg
The Doctor presides over Umbreen and Prem’s wedding. (TV: Demons of the Punjab)
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, before she moved to Sheffield. Meeting Umbreen and her fiancé, Prem, who Yaz had no knowledge of, the Doctor discovered Thijarians near the body of a deceased holy man and assumed they were responsible for his death. However, the Thijarians revealed that they now take the role of witnesses to watch over the dying and 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, but Yaz found a message begging for help on the packing slip. The Doctor took the team to Kerb!am to find the source and 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 disappearances. Shortly after making this revelation, Ryan deduced that Charlie Duffy, a maintenance worker, was behind them, and Charlie revealed his plan to have an army of Kerb!am Men deliver packages with bombs in the bubble wrap to kill 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!)

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)

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)

Attempting to see the coronation of Elizabeth I, the TARDIS instead brought the group 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 to stop her, but the arrival of King James I forced them to investigate elsewhere. The Doctor, Yaz and Becka's cousin Willa Twiston investigated Old Mother Twiston's grave and saw her rise as a Morax just as the Doctor was accused of being a witch, and she quickly discovered that Becka was infected by the Morax Queen who wanted to resurrect the Morax King. However, the Doctor was able to reactivate the prison to suck the Morax back in, but King James killed the Queen, forcing him to promise to end the witch trials and have the events in Bilehurst Cragg be struck 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 above, 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)

The Doctor and her companions travelled to the planet Gatan, arriving in the City of Radiant Stone in the midst of war. The Doctor was caught in the crossfire between two enemy warriors named Tumat and Kraytos who had been fighting for months, causing the destruction of the entire city. With Berakka Dogbolter profiting off of their fighting, the Doctor helped lure them onto 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 them. (COMIC: The Warmonger)

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 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 she found Hanne's father Erik living with his supposedly deceased wife and what appeared to be Grace, upon which the Doctor realised that her grandmother's old bedtime stories about the Solitract were real and that she had discovered the living universe. The Doctor tried to convince Graham and Erik to leave, but both men initially refused to lose their wives again. The Doctor eventually convinced the Solitract into releasing everyone else by offering herself, and the Solitract explained that it 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)

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)

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)

13-Hope-TheBattleofRanskoorAvKolos-1.jpg
"Travel hopefully." (TV: The Battle of Ranskoor Av Kolos)
When the TARDIS picked up nine separate distress signals from planet Ranskoor Av Kolos in 5425, the Doctor went to investigate, where she found Greston Paltraki alone in his ship just as Tzim-Sha contacted him, demanding he give back the package he stole in return for his crew's safety. The Doctor had Paltraki led her and her companions to Tzim-Sha's base for a prisoner exchange. Arriving at Tzim-Sha's "edifice", the Doctor took the package directly to Tzim-Sha and learned that he had fooled the Ux into seeing him as their god, at which point he was healed and created a weapon that could miniaturise planets to take revenge on them opposing the Stenza. However, the Doctor and Yaz were able to get the Ux to see their mistake and return the planets to their original places, with Graham and Ryan choosing to trap Tzim-Sha inside one of his own trophy cases instead of killing him. (TV: The Battle of Ranskoor Av Kolos)

Discovering 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, where the Doctor and Ryan were psychically attacked by a monk named Dominik and she was later attacked by energy and left paralysed, continually muttering nonsense. After recovering, the Doctor learnt that Ruskovitch was trying to prevent the summoning of a twisted figure in the castle's cavern, 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 colony where the Doctor got an audience with Governor K'Lass. K'Lass showed the Doctor his human assistant, Rodney, and eventually got him to confess he thought something was wrong about the mine collapse. 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, including creating the mag-storms. The Doctor disabled the captive Mobox's restraints and 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 next attempted to rescue a worker during a power plant meltdown on Segonus IV but he refused her help due to Berakka Dogbolter's control of the media branding the Doctor as a terrorist. As the Doctor confronted Berakka, a "child of chaos" named Krizanthia Kalos interrupted them to kill Berakka in the Doctor's honour, leaving everyone teleported away in the confusion. Krizanthia used the Eye of M'Dulia to open a portal to the Catastrophia, and with Graham and Berakka safe in a logic cube, the Doctor learnt that the Herald was actually a possible future version of herself, as was its opposite, the Sanity. It wanted to use the Herald to break the Catastrophia into normal reality, destroying it, but a combination of the three selves left only the Doctor. She, Graham and Berakka were rescued by a mysterious woman called Mother G flying the TARDIS along with Yaz and Ryan, and although Berakka still believed the Doctor was a monster, her friends showed her Sharon Allen's more accurate coverage of her actions on a rival news feed. (COMIC: Mistress of Chaos)

Facing the reconnaissance scout Dalek

Thirteenth Doctor and a Dalek.jpg
The Doctor faces a reconnaissance scout Dalek. (TV: Resolution)
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 alien DNA. Back at Graham's house, Team TARDIS found Ryan's absent father, Aaron, had arrived to reconnect with his son. After Ryan left to hear his dad out, the Doctor found that the DNA belonged to a Dalek that had been buried on Earth since the 9th century and was controlling Lin. The Doctor, Yaz, Ryan, and Mitch tracked Lin to a warehouse, where the Dalek had constructed a new casing from scrap, and the whole group tracked it to the Government Communications Headquarters, where they melted its 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

A New Beginning Titan.jpg
The Doctor and her companions watch sentient nebulae. (COMIC: A New Beginning)
Stopping to watch the Sentient Nebulae on Blecplam Two and a Half in 3912, the Doctor and her friends encountered a rip in time that the Doctor recognised as the same anomaly she had encountered before, 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. After a detour that saw them find a war room containing statues of a presumed deity called "The Judge" and what appeared to be war plans, the group finally made it back to the TARDIS safely, before Perkins attempted to hijack the ship at gunpoint, an attempt which was rendered pointless, as the TARDIS had neutralised his weapon. In an act of compassion, the Doctor quizzed Perkins over a pot of tea: he explained 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 the duo refused to bring him new hostages, Schulz was injected with a toxic substance as punishment.

Eventually reaching the Hoarder's resident planet, the Doctor, her friends and Perkins found Schulz, who further 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, curing 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 finding and 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)

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, considering "[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. After Houdini and his wife were captured by Wiseman King, the escaped alien prisoner revealed itself to be Houdini's assistant Billy and explained that he had passed between the various magicians for many years while a control ring linked to his prison pod kept him imprisoned. 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. As she returned the sunglasses, the Doctor discovered that PhiLit of the KaaDok, a race obsessed with Earth's media transmissions, had come to scan Audrey's brainwaves for a wax-droid in her likeness made by his supervisor, AaRee. However, after she and Audrey were teleported aboard AaRee's ship, the Doctor learnt that AaRee had dumped faulty androids on Earth, and also employed child labour, and deposed him, leaving PhiLit in charge after reporting AaRee to KaaDok Major's authorities. (PROSE: Mission of the KaaDok)

Reminders of the past

The Doctor dropped her companions off home so she could do some repairs to the TARDIS in Artron II Recharge Mode. Bored whilst the repairs were ongoing, she discovered an archive of her adventures that her granddaughter Susan had created and settled down to watch them. (PROSE: Press Play) The Doctor travelled to Earth 50 years after the Dalek invasion to visit Susan, who was now a widow. She made her breakfast and invited her to take out her anger on the remains of a Dalek. (PROSE: Fellow Traveller)

The Doctor and Ada Lovelace.jpg
The Doctor with Ada Lovelace. (TV: Spyfall)
Whilst finishing repairs to the TARDIS in Sheffield, the Doctor and her friends were taken away by MI6 where they were told to investigate a series of attacks on all spies across Earth, where she worked with her old friend "O" to find that the attacks were linked to VOR CEO Daniel Barton and aliens called the Kasaavin. After this discovery, "O" revealed that he was actually the Master and was behind the attacks, sending the Doctor to the Kasaavin realm, in which she found Ada Lovelace and could escape to 1834 London. Meeting the Master again in Paris 1943, she learned that Gallifrey had been destroyed and he wanted her to return, so she stole his TARDIS and foiled the Kasaavin's plan, allowing them to take the Master back to their realm with them. The Doctor later returned to Gallifrey, only to learn it had been ravaged by the Master himself because of him discovering the lie of the Timeless Child. (TV: Spyfall) She 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)

After the Doctor accidentally interrupted the mating season of the Deep-Space Squids, Graham revealed he had been collecting coupons for a free holiday, which Team TARDIS was immediately transported to. Arriving at Tranquility Spa, the Doctor investigated strange happenings around the spa which the staff had withheld, discovering that the spa had been a "Fakation" built on an orphan planet. When an old lady named Vilma lost her partner Benni to the local Dregs, the Doctor insisted on them rescuing him, during which they found out that Orphan 55 was Earth in the future and the Dregs were mutated human survivors. Escaping back to the spa, she and the team tried to fight off the Dregs, but, ultimately, Team TARDIS had to escape by teleporting back to the TARDIS, leaving the friends shaken at the possible future. (TV: Orphan 55)

The Doctor tried to take her friends to 51st century New Asgard but instead arrived in Brideport in 1962. There they discovered the town was falling under the influence of a Piggybacker, which had possessed local teacher Edith Harcourt. Working with a family of aliens who had taken refuge from the Piggybackers in the town, the Doctor was able to combat its influence and convinced Abner Endicott to confront Edith, as he was the only resident of the town that Edith respected. As the Doctor had anticipated Abner was able to convince Edith to resist the Piggybacker, at the cost of her life. Team TARDIS attended her funeral two days later. (COMIC: The Piggybackers)

Tracing strange signals to the early 1900s, the Doctor found Nikola Tesla and his assistant, Dorothy Skerrit, being pursued by strange phantom-like beings trying to capture Tesla. Having arrived in New York in the middle of a feud between Tesla and Thomas Edison, the Doctor investigated Tesla's pursuers and found them to alien scorpions known as the Skithra, who required Tesla to repair their stolen Venusian spaceship. Working with Tesla and Edison, the Doctor and her team fought the Skithra when they threatened to destroy Earth to get to Tesla, with the Doctor and Tesla using the TARDIS to electrify Wardenclyffe to force the Skithra into a retreat. (TV: Nikola Tesla's Night of Terror)

Arriving in London in 1969, during the time period the Tenth Doctor and Martha were stranded there, the Doctor was intrigued as to why the TARDIS had brought them there. She sent her companions to keep an eye on her past self, wanting to avoid meeting him, and went to meet Martha at the shop she was working at. Attacks by Weeping Angels and Autons forced them to reunite and the Doctors reluctantly worked together to pit the two invaders against each other. The two Doctors parted, believing they had avoided creating a paradox, however upon taking her companions back to 2020 the Doctor discovered Earth was in ruins. (COMIC: A Little Help From my Friends) Team TARDIS explored London and discovered humanity had been enslaved by Sea Devils for decades. They were taken to a slave camp, encountering Peter and Jackie Tyler among the slaves, but were freed by an attack led by a Skithra Queen. Realising from her that the timeline had been altered in 1903, with the Skithra having now succeeded in kidnapping Nikola Tesla and then awakened the Sea Devils to conquer Earth on their behalf, the Doctor took her companions and the Queen back in time to right the timeline. Along the way, the TARDIS collided with a past version of itself belonging to the Tenth Doctor, who had also been embroiled in this paradoxical timeline and found an alternate version of Rose Tyler. The Doctors stabilised their TARDISes and he and Rose joined Team TARDIS in travelling back to 1903. They found Dorothy Skerritt again who revealed both Tesla and Edison had disappeared. After the Queen and Rose killed the Skithra Drones who were about to awaken the Sea Devils, the Doctors took their team to the Skithra ship. Leaving her past self and companions to find the scientists, the Doctor and Queen went to sabotage the ship to destroy it. After doing so, they were attacked by the present Queen and the rebel Queen insisted the Doctor leave without her. The Doctor returned to the TARDIS as the Tenth Doctor and Fam were bringing the scientists aboard and revealed the Queen wasn’t coming, to her friends’ horror. She dropped Edison and Tesla off back on Earth after which the Tenth Doctor and Rose departed whilst she took her friends to the restored 2020. Whilst there she suddenly realised there was another flaw in the timelines and rapidly left, leaving her friends behind. (COMIC: Alternating Current) She found the Tenth Doctor had been embroiled in the Kotturuh crisis and captured by the Restoration Empire on Skaro. She helped him escape and the two Doctors finally parted ways. (COMIC: Defender of the Daleks) Reuniting with her friends, the Doctor was greeted by the Corsair. (COMIC: Alternating Current)

The Doctor faces impossible truth (FOTJ).jpg
The Doctor uncovers an impossible truth. (TV: Fugitive of the Judoon)
While undertaking another search for the Master, the Doctor was interrupted by the arrival of the Judoon in Gloucester and discovered that they were hunting a fugitive. The Doctor, Ryan and Yaz entered the home of Lee and Ruth Clayton, finding that although they were both human, Lee was hiding something alien, so the Doctor and Ruth hid in Gloucester Cathedral. Later, the Doctor took Ruth to the abandoned lighthouse where she claimed to have grown up, and she regained her memories from a Chameleon Arch and revealed herself as another incarnation of the Doctor. The two Doctors were briefly captured by the Judoon but escaped 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 travelled to a beach in Madagascar, where she found a naval officer in danger who exploded into dust after scales emerged all over his body. With Ryan uncovering similar, he and Gabriela Camara entered the TARDIS with Graham and Yaz, who had gained the company of Jake Willis and his sick husband, astronaut Adam Lang. The Doctor ventured back to Madagascar where she discovered that Adam had been infected with an alien pathogen. While working on an antidote, the Doctor discovered that Suki Cheng was behind it all and the team fled to the TARDIS so Adam could be healed. She tracked Suki to the bottom of the Indian Ocean, who explained about Praxeus before succumbing to it herself, leading the Doctor to disperse the antidote into the atmosphere. (TV: Praxeus)

The Shadow in the Mirror.jpg
The Doctor releases Daughter of Mine. (WC: The Shadow in the Mirror)
After reflecting on her past when she and her companions were forced to isolate on Calapia for three weeks whilst the Death Moon passed over the planet, (PROSE: The Shadow Passes) the Doctor decided to free the Daughter of Mine from her mirror prison and brought the girl back to her home planet. (WC: The Shadow in the Mirror)

The Doctor attempted to take Graham to have a kickabout with Bobby Moore during the West Ham F.C’s glory days in 1964, however instead arrived in West Ham in 1896. There the Doctor and Team TARDIS discovered a Draconian using Thames Ironworks and Shipbuilding Company to build a dreadnought. Unable to persuade them to stop, the Doctor managed to convince the Draconian and company boss to allow the workers’ football team, the precursors to West Ham F.C, to train so they would be prepared for the 1896 Charity Cub Final, avoiding history being changed. (PROSE: The Simple Things)

Whilst Team TARDIS was exploring Hong Kong in 1972, Yaz and Graham were kidnapped by men pursuing a woman named Tung-Mei and the Doctor and Ryan used her dropped pendant to track down Bruce Lee. Eventually, the trio learnt how local crime boss Chen Luo had accidentally exploited a tiny spaceship belonging to the Kalatra, with him raising his champion Shui Long to take control of Earth. Shui and Bruce duelled for the fate of the planet and Bruce ultimately prevailed, forcing the Kalatra to withdraw, taking Chen and Shui with them. (COMIC: The White Dragon)

Journey to Villa Diodati

Thirteenth Doctor dreams (CYHM).jpg
The Doctor sees the Timeless Child in a dream. (TV: Can You Hear Me?)
After dropping Team TARDIS back in Sheffield to spend some time with their friends and family, the Doctor noticed an alarm from 1380 Aleppo, where she found a young woman named Tahira hiding from a Chagaska, just as she received complaints from her friends about strange events at home. Picking up her friends with Tahira in tow, the Doctor followed Graham's visions, which saw them travelling to a space platform in the far future where a geo orb was stuck between two planets in an everlasting extinction event with a woman trapped inside. The Doctor was confronted by the immortal Zellin, who revealed that he had set the trap for her to unlock his long-imprisoned partner, Rakaya, from the geo orb, but she lured them to Aleppo and trapped them both inside the geo orb with the Chagaska. Back in the TARDIS, the Doctor decided to take Team TARDIS to see the creation of Frankenstein as a distraction from the thought-provoking events. (TV: Can You Hear Me?)

Going to Lake Geneva in 1816 Switzerland, Team TARDIS were greeted at Villa Diodati by Lord Byron, Mary Shelley, Claire Clairmont, and John Polidori, but not 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. During this time, the occupants saw the arrival of Ashad - the "Lone Cyberman" - who was in search of the Cyberium, an AI which contained all the knowledge of all Cybermen. After finding Percy Shelley hiding in the cellar, the Doctor figured out that he was the Guardian Ashah seeked, as he had found the Cyberium. The Doctor eventually took the Cyberium from Percy and gave it to Ashad, who then vanished. Team TARDIS then left to find and stop him 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, so the Doctor told everyone to flee to the rescue ships while she caused a diversion. Stealing a Cyberfighter after briefly disabling Ashad, the Doctor, Ryan and Ethan hoped to meet the others at the Boundary. (TV: Ascension of the Cybermen) While experiencing visions of an Irish Gardaí, (TV: The Timeless Children) the group met Ko Sharmus, who led them to the Boundary, which opened to reveal a portal to Gallifrey, from which the Master appeared. (TV: Ascension of the Cybermen)

Forced to accompany him to Gallifrey to prevent him killing her friends, the Doctor was placed in the Matrix by the Master, where she learnt that she was 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 Doctor managed to escape from the Matrix by overloading it with her memories, and was reunited with her friends, Ko Sharmus and the refugees. Together, they destroyed the Cybercarrier that had landed on Gallifrey and retreated to a vacant TARDIS, though the death particle remained inside Ashad after he was killed by the Master. The Doctor sent the humans back to the 21st century in the spare TARDIS while she confronted the Master, who had created a race of CyberMasters from the bodies of the Time Lords, and despite threatening to use the death particle on Gallifrey, Ko Sharmus did the task for her. 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 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. They informed her of Jack Roberson being spotted with a Dalek, and the Doctor went to confront him with Graham and Ryan. When Robertson denied knowledge of building Daleks, he insisted that he was only making security drones run by artificial intelligence, so the Doctor brought him to the factory, which she learnt was a Dalek clone farm being run by a clone of the Reconnaissance Dalek. The new mutants were teleported into the new casings, beginning a takeover of England. The Doctor discreetly lured in the Death Squad Daleks to deal with them, only for Robertson to join forces with them after they had destroyed all the "impure" clones. The Doctor lured the Daleks into the spare TARDIS, which she programmed to fold in on itself and go into the Void, destroying them. 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 him, 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)

Lone travels with Yaz

After an argument with a Silurian, a Judoon, and a Hath, the Doctor and Yaz got trapped in a joke book, and had to work out what the oldest joke in the universe was to escape. (PROSE: Knock! Knock! Who's There?)

Death

According to one account, the Doctor regenerated into her successor in the TARDIS. She was alone when she regenerated. (PROSE: Contents)

The Masked Assassin
Death List Dalek.JPG
The Doctor hides behind a Dalek. (PROSE: The Death List)
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)
Tying up loose ends

The Doctor once posed as a museum curator in Venice. Missy 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)

While sitting on a bench in Henry VIII's third-favourite garden, the Doctor thought about the lesson the Moment had wanted to impart on the War Doctor. The Moment then joined her on the bench, and when the Doctor asked her why she had helped him the day he saved Gallifrey, the Moment said it was because she did not want to be used. The Moment appeared again a year later to continue their conversation when the Doctor stood in a fountain at the heart of the Villengard banana groves. The Moment told her that she helped because the universe had a need for the Doctor, and, at that point, they were in danger of stopping. Pleased that she finally had an answer, the Doctor went back to the TARDIS with a renewed vigour. (PROSE: The Day of the Doctor)

When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the Thirteenth Doctor learnt that Earth was under threat from a pandimensional entity that had trapped her fourth incarnation in his TARDIS. While the Thirteenth Doctor argued with her other incarnations, the War Doctor used encoded messages from the Sixth Doctor to stop the invasion before it began, and the Sixth Doctor installed a way to expel the entity from the Fourth Doctor's TARDIS, ending the crisis. (WC: Doctors Assemble!)

Other solo activities

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)

Thirteen in 'Twas.jpg
The Doctor on the phone with Santa. (WC: 'Twas the Night Before Christmas)
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)

When the Fourth Doctor was trapped in the pocket dimension controlled by the Scratchman, the Thirteenth Doctor visited him to give him a reminder of what he stood for and what he had to be in order to encourage him to hold on to his true identity against the Scratchman's power. Once her fourth incarnation, Sarah Jane Smith and Harry Sullivan were back on Earth, the Thirteenth Doctor visited the Fourth Doctor to muse on how important it was that they never give up on being the Doctor. (PROSE: Scratchman)

The Doctor once contacted Bonnie and Osgood via text message, complaining about how she was stuck in a time eddy, trapping in her repetitive boredom. (WC: The Zygon Isolation)

The Doctor met up with her wife River Song and penned a short contribution to The Dark Times Times, a newspaper where River documented the multi-sided conflict between the Kotturuh, the Dalek Empire, the Doctor and the rest of the universe during the Dark Times. (PROSE: The Guide to the Dark Times)

Fearing she may one day become trapped somewhere and need someone else to save the Earth in her absence, the Doctor compiled a book about her life and adventures to help someone protect the Earth in her absence. (PROSE: Meet the Fam) In her book, she included fact files on her latest adventures, (PROSE: Fact File) reviews of recent destinations she has visited, (PROSE: TARDIS Trip Reviewer) a tour of her TARDIS control room, (PROSE: TARDIS Tour) her own write up on legends of the Timeless Child, (PROSE: The Secrets of the Timeless Child) and an extract from the The Dark Times Times newspaper article about the Dark Times, written by River Song. (PROSE: The Guide to the Dark Times)

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

Psychological profile

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 Missy 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)

Thirteenth Doctor mic (Resolution).jpg
The Doctor speaks with the reconnaissance scout Dalek. (TV: Resolution)
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 the Master 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 the Master 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 the Master. (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 Missy 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 the Master 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)

ThirteenScrunchesFace.jpg
The Doctor inspects a spider. (TV: Arachnids in the UK)
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)

Clothing

Main attires

The Doctor unveils her new outfit. (TV: The Woman Who Fell to Earth)
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)

Behind the scenes

The first female Doctor

AFTER Dr WHO... Dr HER?.jpg
Article in the Daily Star.
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."[1][2] 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".[source needed]

Second Doctor actor Patrick Troughton was quoted in 1983 as approving of the idea of a woman playing the Doctor.[3] 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 Frances de la Tour and Dawn French also being mentioned.[4] 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[5], 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 Judi Dench.[6][4] 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."[source needed]

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. [4] 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 Missy, 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".[7]

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.
