Fifteenth Doctor


*The following article is written from an In Universe perspective.*

The Fifteenth Doctor was the second incarnation in the Doctor's new regeneration cycle, and travelled, initially, with the Fourteenth Doctor's companions, Raleigh Baker-Mitchell and Pete Fletcher.

Biography

Post-Regeneration

The Fifteenth Doctor came into life after the Fourteenth was converted into a Cyberman. She was joined by companions Erin, Kyle, Gemma, Hogan and Zenla present. She was initially very confident, as she got to work, straight away, telling everyone except Zenla and Caitrin to stay on Mondas, and do their best to make sure it was destroyed by the end of the night, like her own personal history stated. She, Zenla and Caitrin then journeyed in the TARDIS to the South Pole, where her first incarnation was living out his final day, all the while, the Cybermen and the Master were attempting to avert the destruction of Mondas. The Doctor, along with the other two, did their best to preserve the timeline, and battled the Cybermen.

However, the Master arrived back in the South Pole, with the Doctor's current companions, Raleigh and Pete and revealed Raleigh as working with him, although Pete had no knowledge of this. The Doctor was especially hurt and betrayed, but she showed little emotion on the outside and with the help of her team on Mondas, who blew up the planet with several nuclear devices, and herself at the South Pole, as she, along with Caitrin, Zenla and Pete, sent out a cybernetic virus which scrambled the Cybermen's brain waves and killed all of them, keeping them out of the way of her past self.

During this confrontation, Raleigh turned back to the Doctor's side, but the Doctor still had little trust in her, at least until she took the Master by herself in the UNIT Time Machine to Mondas and left him there to die, as the last part of it was destroyed. The Doctor then accepted that Raleigh wasn't going to betray her again and invited her to continue travelling with her in the TARDIS. The Doctor returned, a few minutes later, with the TARDIS, to drop everyone back home. During this time, she picked out a new outfit, consisting of a black top and a rugged leather jacket, as well as having shaved her head. She showed little emotion while saying goodbye to everyone, but she broke when she has to say goodbye to Zenla. (DW: The Third Planet)

Adventures with Raleigh and Pete

The TARDIS landed during the frost fair of 1814. Deciding to explore the fair, the Doctor and Pete noticed green glowing lights under the ice and learned that the urchins were getting paid to lead people onto the ice. The Doctor decided to venture under the ice with Pete and Raleigh to see what was in the Thames and found a large fish-like creature chained down to the riverbed. Investigating the nearby river dredgers, the Doctor learned that the creature's waste was being dug up as a supplement for coal on Lord Hanson's orders.

Captured by Hanson's men after the Doctor assaulted him for his racism towards Pete, Hanson revealed that he was the leader of the 'government' from Raleigh's times and had sent her back to infiltrate the TARDIS. Hanson then tied Pete and the Doctor up in a near a dynamite-laced-tent, but they were able to escape. Leaving Pete to clear the River of people, Hanson, realising he had the upper hand, have Raleigh an ultimatum and said he wouldn't set off the bomb if she stood with him and joined his side. Raleigh joined Hanson who instructed the Doctor on how to defuse the bomb. This caused the explosives to free the creature. The Doctor and Pete confronted Hanson and Raleigh, and in anger, the Doctor teleported both Raleigh and Hanson away, to what she thought, was their death. Back in the TARDIS, the Doctor justified her action unconvincingly to Pete, but he, surprisingly, agreed with her. (DW: The Last Winter)

Meeting Sally

The Doctor and Pete arrived in the village of Beasmere where they learned that several children from Madison Road Primary School had gone missing. Deciding to investigate, the Doctor posed as a new teacher where she befriended Sally Brennen, a fellow teacher whose granddaughter Jade was in the Doctor's class. After agreeing to let Sally help investigate, they both discovered that children were being possessed and that this had been going on since a new biometric security system had been introduced two months ago by Oliver Griffiths who was the new Educational Secretary. The Doctor called in UNIT and together, they severed the connection between the aliens and the bi-metric system.

It was then revealed that Oliver Griffiths was working with the Rutan Host who had kidnapped the children to use in their war against the Sontarans. The Doctor with help from Sally, Pete, UNIT and a mob of angry parents defeated the Rutan troops that had been sent to take the children and destroyed the Rutan ship and the school. After meeting Sally's wife, the Doctor offered Sally the chance to travel with her and Pete. Sally was initially reluctant, but she was soon convinced and went with the Doctor and Pete.

Exploring the Universe

In order to prove to Sally how powerful the TARDIS was, the Doctor took her and Pete to 28th Century Earth where they became caught up in the assassination of the System Security Council. Wanting to figure out who the one assassin never caught was, the Doctor, Pete and Sally eventually tracked down the assassins and discovered that they were a group of extreme Earth Nationalists who didn't believe in the expansion into space or sharing resources with other planets. The Doctor confronted Krasko, the leader of the group who revealed that he'd stolen a vortex manipulator and used it to travel back in time. (DW: The Assassins)

Following Krasko, the TARDIS arrived in Montgomery, Alabama in 1955. Soon, Pete was assaulted due to his skin colour, and the trio ran into Rosa Parks, as Krasko's plan soon became clear. Stopping Krasko at every turn, the Doctor, alongside Pete and Sally, managed to keep history on track even realising that they were always part of the events and they ensured Rosa was arrested after refusing to follow James Blake's order to move seats. (DW: Rosa)

Soon after, the Doctor returned her companions to Beasemere, where she soon became enthraled in the mystery of some very out-of-character behaviour from the villagers. The Doctor later found out that an entity called Miss Mercy was cloning the villagers and replacing them to feed on their mental energy. After rescuing Sally's wife, Annie from her, the Doctor managed to abbreviate Miss Mercy's power, terminating her existence. However, as a dying request, she asked the Doctor to go to her home planet, Kaelia, and save her people. (DW: The Haunting)

Arriving on Kaelia, the Doctor, and her companions were soon captured by a race of savages, known as the Dervishe, who they found out were being oppressed by a race of invaders called the Teruians. The Doctor agreed to help the Dervishe gain their freedom, only for her to discover that the Dervishe were actually a subsection of Teriuans eventually realise that both groups were pressing Miss Mercy's people, the Kaelians - the indigenous population. The Doctor discovered that the two races weere using a machine to keep the Kaelians' mental energy limited, and she, along with Pete, Sally and a scientist, Dr Gaerair, blew up the machine and freed the Kaelians. (DW: Open Minds)

The Doctor took Pete and Sally to Comercecilla, a giant shopping planet, home to every conceivable item in existence. However, split up from her companions, the Doctor discovered murmurs of disappearances all over the planet. She investigated, soon discovering that the last remnants of the Daleks had been kidnapping customers and turning them into new Dalek mutants. The Doctor managed to kill all the Daleks, by cracking open the partially converted mutants' incubator tanks and releasing them, who attacked their captors before dying themselves. The Doctor assumed after this that the Dalek race was truly extinct. (DW: Comercecilla)

After a TARDIS malfunction, the three travellers made a forced landing in 1819 Manchester, where they were unwitting testimonies to the horrific events that took place on the city during the Massacre on St Peter's Field. (DW: The Peterloo Massacre)

In the midst of an adventure, the Doctor uncovered a race called the Memorphians behind the most terrible threat - but more curiously, she discovered that Pete had encountered them before, long before he met her. Using his knowledge, the trio managed to defeat the Memorphians and save the day. (DW: The Conspiracy of PriceMart)

The Doctor and her companions landed unknowingly, on Taoter III, the future-home-planet of the Vex and the Time Lords, and the home-planet of her former companion, Raleigh. After investigating the mystery of who killed Barnley Macon Stanley, the Doctor ran into Raleigh, who was working on a project to try and avert the Vex invasion of the universe. With Raleigh fearful of the Doctor derailing her plans, she ordered the Doctor to be killed, to which the Doctor and her companions managed to escape into the TARDIS from, at the last minute - leaving Raleigh to intact her plan. (DW: Angels of Time)

Reunion with the Rogue

After arriving back in Beasmere, the Doctor and her companions found themselves in the midst of a general election campaign and in Beasemere, local MP Oliver Griffiths was campaigning. Predicting Griffiths could be up to something, the Doctor began investigating his actions, only to find that Griffiths himself, believed that aliens were tampering with his life. The Doctor, acting on this information, helped Griffiths find the truth, taking them to Griffiths' old cottage, whereby in the cellar, the Doctor found a chest with the Seal of Rassilon, which was in fact a vessel for a Time Lord's consciousness from the Chameleon Arch - that of the Rogue's. After Griffiths opened it and inhaled the Rogue's consciousness, he threatened the Doctor and left in his TARDIS. (DW: The Sinister Minister)

Trying, but failing, to get a trace on the Rogue's TARDIS, the Doctor decided to visit the Rani on Miasimia Goria. Eventually, the Doctor persuaded the Rani to help and he harnessed the TARDIS' energy field to detect the Rogue's TARDIS' artron energy signature. The Doctor followed it, finding herself landing once again on Taoter III but over a thousand years in the past, just after the Scallatti had settled there. She, and her companions, then followed the Rogue, Raleigh, Hanson and the Scallatti's President, Ajacos, into the base of a secret organisation called the Three. Inside, the Doctor observed them meeting with three elders, Utnaphistim, Shamash and Ersiah. However, after the revelation that Ersiah was an older incarnation of the Serreti Rogue, the Doctor and her companions, revealed themselves to the room - as Ersiah told them that they must work together to stop the Vex invasion.

Ersiah went onto order the Doctor to lead the mission, but they were all stopped when the Rani disabled the TARDISes, telling them that they need to sort everything out. The Doctor agreed with the Rani and made the case that maybe they just all needed to talk. The Doctor, over the course of several hours, talked and negotiated with the Rogue, Raleigh, Ersiah and the Rani in an attempt to sort everything out. With the Doctor's help, it was agreed that the past would be left alone, Ersiah would be released, the Three would be reformed, and for the Rogue to begin again and help the Rani rebuild Miasimia Goria.

The Doctor, Broken

Returning to the TARDIS, Raleigh ran over to the Doctor in tears, pleading for her help, but before the Doctor could say anything to her, Pete intervened and pushed Raleigh onto the ground, telling her she wasn't welcome. However, after the Doctor, Sally and Pete set to flight, the Doctor told Pete that he had no right to do that, and they should've given Raleigh a chance - ending in the Doctor throwing Pete out of the TARDIS after taking him back home. This ended up angering Sally, who looked at the Doctor in disgust, before storming off and leaving herself - leaving the Doctor alone and isolated, and deeply upset. However, not long after, a strange old man, teleported into the TARDIS, introducing himself as Daniel Bevin and asking the Doctor for her help. (DW: False Prophets)

Daniel, a Space Security Office from the 41st Century, proceeded to teleport the Doctor into his office on Mars, telling her of a recent attack by the Ice Warriors upon the human colony. Daniel went onto explain that ever since Earth voted to leave the Galactic Federation, tensions had been at an all-time high, and the Ice Warriors wanted the human colony to leave their planet. The Doctor, was initially reluctant to help, still reeling from losing Raleigh, Sally and Pete, but she eventually agreed to help mediate the situation and find a peaceful solution. At the eleventh hour, she managed to broker a settlement between the Humans and the Ice Warriors, but suddenly the Chief Ice Warrior was gunned down, causing chaos - to which the Doctor turned around to see the Master standing there, laughing in her face.

The Doctor, confronting the Master, found out that he had been stoking up tensions between the two races - but did not cause the leave vote, as they did that by themselves. However, after Daniel sacrificed his life to kill the new Chief Ice Warrior, who had been working with the Master to arrange the initial attack and the old Chief's execution, the Master tried to escape from Mars - to which the Doctor tricked him into 'escaping' to a ship of angry Ice Warriors, who knew of the Master's role in the Chief's assassination. The Doctor then managed to, on the back of Daniel's honourable death, agree on a new deal with the Ice Warriors, allowing the human colonists to remain on the planet, indefinitely.

Reconciliation with Pete

Attending Daniel's funeral, the Doctor reflected on her recent loss, and decided to try and make some amends with Pete, by visiting him and apologising to him - the two ended up hugging before the Doctor invited him to join her in the TARDIS again. (DW: The Martian Equinox)

The Doctor and Pete arrived in San Francisco in 2018, where they were present during which an alien spacecraft crashed into the atmosphere, and uprooted the Golden Gate Bridge with Pete on board, the Doctor falling into the river below. Separated from Pete, the Doctor worked with the American branch of UNIT, as she helped to get the spaceship back to Earth, and the Bridge and all the people on it returned. When they managed this, Pete told the Doctor how the Raston Warriors were behind everything and were looking for an ex-sleeper-agent, who he managed to protect and get back to Earth. (DW: Chain Reaction)

While travelling in the Time Vortex, the TARDIS was boarded by a Kerb!am Man to deliver a scarf the Doctor had ordered in a previous incarnation. On the packing slip, Pete found a message begging for help. The Doctor took him to Kerb!am to find the source of the distress call and they began investigating the mysterious disappearances of workers. The Doctor eventually determined that the Kerb!am AI itself had sent the distress call in response to the disappearance of the employees.

Shortly after making this revelation, Pete deduced that Charlie Duffy, a maintenance worker, was behind the disappearances, and Charlie revealed his plan to have an army of Kerb!am Men deliver packages with bombs in the bubble wrap to kill Kerb!am customers and prevent automation from completely replacing a human workforce. The Doctor was able to reprogram the robots to open their own packages and detonate the explosives within, destroying the army and killing Charlie when he refused to escape with the Doctor. (DW: Kerblam)

The TARDIS landed in 1623, Colonial America in Virginia, putting the Doctor and Pete directly in danger, and without the help of the perception device. The Doctor and Pete experienced the brutality of the British Empire, and the horrors they committed, not only on black people, but also on the Native Americans, with whom the two of them befriend, and save a tribe of. (DW: Coats of Blood)

After landing on Tolia, 500 years since the Doctor's last visit, the Doctor and Pete found themselves wrapped into a civil war, between the Northern and Southern continents of the planet. Separated from the TARDIS, the two of them had to fight to make it through the warzone, and resist the urge to try and broker peace between the two sides, as the Doctor came to realise that stopping a planet-wide civil-war was even too much for her. Eventually, the two managed to get back to the TARDIS and escape from the bloodshed planet. (DW: Terror on Tolia)

Reunion with Sally and Annie

Detecting alien life signs, the Doctor lands the TARDIS on a Eurostar train, making its way to Paris. After being reunited with Sally and Annie, who were coincidentally on the same train, the Doctor fought off a lone Sontaran, hell-bent on conquering the Earth, who was being transported across Europe by a group of vigilante alien hunters. During the events, the Doctor managed to reconcile with Sally, who apologised to the Doctor, but she said that she would rather stay on Earth with Sally - but as the group were saying goodbye in the TARDIS, it began to take off, unplanned, taken over by a hostile force, and bringing Sally and Annie along with them. (DW: Friends on a Train)

Travels with Pete, Sally, and Annie

After several minutes of unplanned flight, the TARDIS eventually stopped dead, with all its power drained. The quartet made their way, slowly out of the TARDIS to find themselves on a Victorian ship, on a voyage to America. However, as the quartet spent more time on board, they began to discover that people were one by one disappearing, and the Doctor uncovered that the Weeping Angels were behind it. As time began to ran out, the quartet found a prisoner on the boat, just as the Angels began to close in on them - the Rogue.

As soon as the Angels touched the quartet, however, the walls fell down into a virtual abyss, showing them their true environment, a Dalek prison. Intent on getting back to the TARDIS, the Doctor, Pete, Sally and Annie were persuaded by the Rogue to help him escape, also. With the prison guarded by the Weeping Angels, the five escapees managed to engineer the situation, as so the Weeping Angels sounded the Daleks, sending them all back in time. But before they all reached the TARDIS, the Doctor was horrified to witness Sally being taken by the Angels and sent back in time. (DW: God's Familiars)

On course to rescue Sally, the Rogue took over the TARDIS and sedated the Doctor and her friends. Tempted by visions of her truest desire, to rid the universe of pain and suffering, the Doctor managed to break free and stop the Rogue. However, instead of throwing him out of the TARDIS doors into the vortex, as she contemplated, the Doctor forgave the Rogue and asked for the two of them to build up some trust again, especially after finding out he just wanted to return to Miasimia Goria to help the Rani fight off the Daleks. The Doctor then managed to pilot the TARDIS to 17th Century Paris, where they tracked Sally to, and rescued her. (DW: Bliss)

Arriving in 15th Century England, the Doctor, Pete, Sally, Annie and the Rogue found themselves in the midst of Richard III's downfall, which the Rogue tried to capitalise on and manipulate events so he could take the throne. The Doctor managed to stop the Rogue, keeping history in order, but only at the expense of stranding the Rogue in the 15th Century, having to fend for himself. (DW: Crookback)

During an adventure in 21st Century London, the Doctor was separated from her companions. (DW: Their Story) Shortly after, she was abducted and teleported onto a Pirate Collective Ship, taking her to be sold as a slave to the Master. The Master took the Doctor to an alien spaceship, which after he took her to an empty room, as he agreed with the owners of the ship, the Doctor discovers that a whole new empire of Daleks were behind everything - but to the Doctor's surprise, they asked for her help. The Supreme Dalek, to whom was one of the survivors of the Doctor's genocide of the Daleks on Comerecilla, went onto tell the Doctor that the DNA of the new Daleks was unstable and they needed the life force of a Time Lord to survive.

Telling the Daleks 'No', they threatened to exterminate her, however, in the nick of time, the Master teleported her into his TARDIS, saving her life, so they both could get rid of the Daleks in an alliance of convenience. The two of them arrived on Earth, reunited with Pete, Annie and Sally, as well as their son, Ricky, and their granddaughter Jade, who joined them in the TARDIS, as all seven, with the help of UNIT, fought against the Daleks as they invaded Earth. The Doctor and the Master, sometimes into the battle, took the TARDIS back to when the Supreme Dalek managed to survive, as the two of them end up creating the event which caused the Dalek DNA to mutate, in a bootstrap paradox. Arriving back in the battle, Sally suggested to the Doctor that as the DNA is unstable, at some point it would kill the Daleks, so the Doctor, using both her and the Master's TARDIS, and UNIT's help, created a temporal rift around Earth, affecting solely Dalek DNA, ageing them to death - with just the Supreme Dalek left.

Boarding the Dalek ship alone, the Doctor confronted the Supreme Dalek, ready to kill it. However, after the Master killed Sally, Pete took the Master's TARDIS up to the Dalek ship, as he swapped with the Doctor, and told her about Sally and the danger that Annie, Ricky and Jade were in. Pete aimed the gun at the Supreme Dalek, shooting it. Arriving back on Earth, the Doctor saw the exploding Dalek ship, as Pete also, inadvertently, caused the ship to self-destruct. The Doctor, then punched the Master in the face, and aimed a gun at him, before she realised that it would be completely wrong to kill him, and instead stranded the Master on prehistoric Earth.

Sometime later, the Doctor attending Pete and Sally's funerals, to which she bidded farewell to Annie as she agreed to continue travelling hopefully and to have a good life. (DW: The New Empire)

Return to the Death Zone

The Doctor intercepted her previous incarnation, using an intergalactic transport hub when she needed help with saving her previous incarnations, as one by one they were being taken out. The two tracked the threat to Chicago in the 1880s, where they found the enemies base of operations, but with only a single suitcase inside - with figurines of all of their thirteen past selves. Realising that someone had been using a time scoop, the two Doctors travelled to the Death Zone, on Gallifrey before the fall. The Doctors journeyed to the Tomb of Rassilon, where, as the Doctor had guessed, they found Borusa, aiming a staser at them.

The Doctor talked Borusa down and told him that his lust for power was too great, but that she'd free him if he apologised. Borusa ended up breaking down in guilt, before the Doctor held him in her arms as he let their other incarnations go. Returning her previous self to Civil-War era D.C., the two Doctors said goodbye, with the Doctor very tempted to warn her earlier self about Raleigh's true motives, but stopped herself in order to keep the timeline in check. (MINI: The Emerald Terror)

Meeting Bertie

After the TARDIS arrived in 3289, the Doctor decided to go undercover on a Gaian ship as one of their officers, in order to help the resistance dismantle the Gaians' stranglehold on planets that had subjugated indigenous species. Communicating with Sam Reynolds on the planet Erstden, the Doctor helped organise an attack on Meena Patel, one of the Gaians' most ruthless officers, after she and the Doctor landed on Erstden. However, during the attack, one of the resistance members came into contact with a melted block of strange parasitic ice and transformed into a being taken over by a lifeform the Doctor recognised - the Flood.

Pretending that she had encountered the Flood on a previous assignment as a Gaian officer on Mars, Patel ordered the Doctor to work with captured Erstden scientist, Bertie Reynolds on securing a cure for the parasite. However, Patel told the Doctor that if a cure was not found, she was to use the secret weapon, the Doomsday Cannon, which was being built on Erstden, to blow up the planet, which would, as an added bonus for Patel, get rid of the resistance too. After failing to make an antidote, despite the Flood infecting more and more people, shortening the amount of time they had, the Doctor took the decision to begin an evacuation of Gaian officers, in preparation to destroy the planet and the Flood with it. During this time, Bertie admitted that his daughter, Sam, was the leader of the resistance, as he pleaded for the Doctor to save her, before the Doctor also admitted that she was a spy, working for the resistance and that she had come to know Sam very well.

Upon returning to the Gaian ship and finding Meena Patel dead at the hands of the Flood and Sam, the Doctor and Bertie decided to also evacuate everyone else onto the TARDIS, as Bertie prepared to use the cannon. However, in the control room, through the window, Bertie saw Sam outside and ran out to her, abandoning the cannon and putting the survivors in direct danger. Seeing the risk, the Doctor decisively materialised the TARDIS around Bertie and Sam and rescued them, before she herself activated the cannon and destroyed the planet. After dropping off the survivors on a planet 200 light-years away for their own safety, the Doctor offered Bertie the chance to travel with her in the TARDIS, to which he initially refused, but after finding out it was a time machine, his curiosity as a scientist encouraged him to take the decision to join the Doctor onboard. (DW: The Doomsday Cannon)

Travels with Bertie

Deciding to prove to Bertie that the TARDIS could in fact travel through time, the Doctor piloted the TARDIS to Earth, 2019. The two found themselves in the Yorkshire Moors and soon heard gossip about a skeleton found in a warehouse, prompting the Doctor to investigate. After being arrested by the local police and proving their scientific knowledge, the Doctor and Bertie helped investigate bright lights found under the warehouse which turned out to be a spaceship. After getting into the spaceship's computer system, the Doctor learned that the ship came from Earth. She and Bertie witnessed the skeleton regranting itself into a Silurian known as Tunstuona.

The Doctor and the others learned that the Silurian was part of a colony of Silurians that had left Earth millions of years ago and settled on a planet lightyears away. The Doctor eventually took Tunstuoma to the Silurian colony world only to discover that all the Silurians had gone into hibernation. After deciding to stay on the planet, the Doctor said goodbye to Tunstuona, before returning to Earth to pick up Bertie. (DW: Homeland)

The Doctor took Bertie to meet Emily Davison in 1913, but the two of them soon became involved in a Memporhian plot, which would alter a key-fixed point in time - Davison's death. When confronting the Memporhians, the Doctor and Bertie met their leader, who was, much to their surprise, Bertie's daughter, Sam, who met the Memporhians in her own time, where they told her that she could help prevent the Gaian rule of the future, but as events transpire, Sam revealed that she was hurt by the Doctor and Bertie leaving her - them just vanishing into thin air, seeing it as a rejection from her father.

Leaving Bertie to talk Sam around, the Doctor tried to deal with the Memporhians, ending up at the 1913 Derby, whereby the Memporhians disappeared into the crowd, adopting new hosts. Reuniting with Bertie, and a reformed Sam, the Doctor managed to piece together a device which highlighted all the lifeforms the Memporhians were in control of, including her suspicion - the King's horse, which in this case wouldn't kill Davison, as history planned. With the help of Sam, weakening their field, the Doctor and Bertie managed to extract the Memporhians from the horse, allowing history to go as planned with the Memporhians defeated. (DW: The Long Struggle)

Not long after, the Doctor, alongside Bertie and Sam, returned to 2019, as they began investigating a number of strange goings-on. Splitting up, the Doctor found herself in Madagascar, whereby she met scientist Suki Cheng and a washed up body in the sea, which seemed to be infected by some sort of virus that soon destroyed the body. However, not long after a squad of helicopters invaded the skies and requisitioned the Doctor's services, taking her back to the UK.

Once on British soil, the Doctor was taken to meet with the Prime Minister, Michael Apperley, who told the Doctor that they needed her help, for, annoyingly, the same problem the Doctor was already investigating, although they granted her the full resources of UNIT and the Secret Service. Picking up Bertie and Sam, alongside a few others, the group were attacked by thousands of birds, which after dissection, seemed to be controlled by microplastics. The Doctor managed to get the TARDIS to the centre-point of the signals, with the group finding themselves in a base deep under the Indian ocean, whereby the Doctor came face-to-face with Suki, who revealed she was trying to find an antidote to a virus which infected her home planet by the Nestene Consciousness and was using Earth as a testing ground. Putting a stop to this, the Doctor, with help from the others, managed to synthesise an antidote and distributed it. After saving the planet, Apperley thanked the Doctor and offered Sam a place at UNIT, as the Doctor and Bertie to left in the TARDIS. (DW: Praxeus)

Arriving in the East End of London in the 1930s, the Doctor and Bertie became acquainted with a Jewish barmaid called Deborah, as the Doctor realised they had arrived not long before the Battle of Cable Street, the aftermath of a facist march led by Sir Oswald Moseley. However, upon attending one of Moseley's rallies, the Doctor suddenly became aware that Moseley was in fact the Rogue in disguise.

The following morning, the Doctor and Bertie set out to defeat the Rogue, and ensure the Battle went as history intended, with the residents of the East End defeating the British Union of Facists. The Doctor soon foiled the Rogue's plan, and found herself having to replace him with the real Moseley, who had been locked up in a cellar. After wrestling with the idea of whether or not to allow the real Moseley to return into the fold of history, the Doctor found herself tempted, but soon did what was right. After the Rogue made his escape, the Doctor received a phone call in the TARDIS asking for her help. (DW: The March of Evil)

Death

The Doctor was contacted by Sam and learned that the Rogue had become Prime Minister of Great Britain, she and Bertie travelled to 10 Downing Street where the Rogue revealed that he was using the hatred and toxicity of the early 21st century to create a fascist movement and gain complete control over Earth. The Doctor, Bertie and Sam were detained and the Doctor soon realised that the Rogue was communicating with a third party. The Doctor managed to escape to the TARDIS and followed the Rogue's signal, only to arrive in a white void.

The Doctor was sedated and suddenly found herself as the master of a manner on a Victorian colony planet, inhabited by humans and Silurians, however, she eventually realised that everything was fake, and soon escaped back into the void, where she reunited with Bertie and briefly met an alternate version of herself. The two were then confronted by the Toymaker, who as it turned out had been testing the Doctor, and had one final test planned that would decide the fate of millions of versions of herself.

The Doctor and Bertie returned to the TARDIS and arrived on a mining transport vehicle that had been hit by an ion storm an hour before. After freeing the two occupants from a quarantine booth, the Doctor and Bertie discovered that a virus had infected the very fabric of the ship from the storm. The Doctor found herself in a no-win scenario where she could've either detonate the ore and kill everyone on their ship as well as the entirety of the nearest system, or jettison the ore, whereby it would've collide with the ion storm, and wipe of far more than just the nearest system. Thinking outside the box, after evacuating the rest of the ship, the Doctor installed a forcefield around it and ignited the ore, sacrificing her life.

The Doctor found herself back in the void with the Toymaker, who explained that he was testing her to see if she and all alternate versions of her were worth keeping. He then informed her that he was leaving and that all his pocket universes would be folded into the main universal plains. The Doctor returned to the TARDIS and to the main universe where she stated "Never cruel or cowardly... that's our promise, all of us." She then regenerated into her next incarnation. (DW: Her Final Stand)

Personality

As the Fifteenth Doctor was born into the middle of an ongoing conflict, the rest period after regeneration was not available to her, and her early hours in her new body went onto mould her personality throughout her incarnation.

She didn't usually display her emotions while at rest, instead, only letting the mask slip when prompted. She also lacked a lot of the pomposity of her themselves, but not to the point of insecurity, but more like she was always thinking and calculating, in her head. She disliked show-offs and preferred to act in a much more suave manner.

However, she was also, arguably, the most down-to-earth of her incarnations, often using colloquial vocabulary and dressing in a leather jacket, which seeped into, and personified her new personality.
