War Doctor

Originally young and robust, the ninth incarnation of the Doctor, christened the War Doctor by Alice Obiefune, set upon the warrior path for which he had been intended, and disavowed the name "the Doctor". Though the Time Lords and Daleks continued to refer to him by that name, he was also referred to as "the Warrior", the "Doctor of War", and "the Renegade", but, as far as the Doctor was concerned, he had no name.

As he fought alongside the Time Lords, he became regarded as a war hero who commanded a great deal of respect from the Time Lord military. One soldier stated that, during the Time War, the War Doctor was noted for going into battle unarmed, but winning nonetheless, with his unarmed state being the last thing many saw.

After becoming old, battle weary and faced with the end of reality, the Doctor considered activating the Moment to end the Time War by committing genocide against both the Daleks and his own people. However, the Moment's sentient interface led him down a different path by letting him view his future first-hand. By teaming up with his future selves, his mind was opened to a peaceful way to end the Time War in lieu of the deadly alternative he was going to enact. Teaming up with past and future incarnations, the War Doctor helped to save Gallifrey from destruction; although he was not able to retain these memories, believing himself to have destroyed Gallifrey due to the timeline being out of sync.

After departing from his future incarnations' company, and once again embracing the name of "the Doctor", this incarnation regenerated into a younger form due to advanced old age.

A day to come
After the First Doctor was diverted from the South Pole, (AUDIO: The Bonfires of the Vanities) he learned from the Player that "forces from the future" were interfering with the Doctor's history to stop him from becoming an incarnation that would play a key role in the future conflict. (AUDIO: The Plague of Dreams)

The First Doctor was referred to as "the Doctor of War" by the Testimony, who also showed him footage of the War Doctor, as well as his ten other successors, when he expressed doubt over the Twelfth Doctor's identity. (TV: Twice Upon a Time)

Mawdryn attempted to force the Fifth Doctor to use up his eight remaining regenerations to end his follower's cycle of perpetual rebirth, but this was rendered unnecessary when Alistair Gordon Lethbridge-Stewart made physical contact with his younger self and a discharge of temporal energy was released that allowed Mawdryn and his followers to die. (TV: Mawdryn Undead)

After the TARDIS became "stalled in the equivalent of a galactic lay-by", the Sixth Doctor had a worried thought of Peri Brown growing old and dying in the TARDIS, while he would "go on regenerating until all [his] lives [were] spent." (TV: Vengeance on Varos)

When exposed the Valeyard's alliance with High Council to the Sixth Doctor at his trial, he revealed that the Valeyard was acting as the prosecutor for the trial in exchange for the Doctor's remaining regenerations. (TV: The Ultimate Foe)

When Ace was sent into the Seventh Doctor's mind, she discovered a room with thirteen cubicles, seven of them empty, while the other six contained shadowy white figures, representing the Doctor's future incarnations. (PROSE: Timewyrm: Revelation)

After sealing Gallifrey away in a pocket universe, (TV: The Day of the Doctor) the Seventh Doctor was able to recall teaming up with his other twelve incarnations to save Gallifrey. (AUDIO: Cold Fusion)

After using a Deathworm Morphant to posses a human body, tried to use the Eye of Harmony to steal the Eighth Doctor's remaining regenerations to heal himself, but his plans were foiled when Grace Holloway sent the TARDIS' into a temporal orbit. (TV: Doctor Who)

After his chest was crushed by sandbags, the Eighth Doctor experienced a coma fantasy where he was walking through a series of corridors, troubled by the sensation that his body was a coat that he had taken off and he would find another one around a corner. However, his connection to Sabbath Dei prevented the Doctor from regenerating due to his second heart beating in Sabbath's chest keeping the Doctor alive as well. (PROSE: Camera Obscura)

Prior to his arranged execution on Tor-Ka-Nom, the Eighth Doctor told the attending priest that he believed in reincarnation, but that he had "a nasty feeling it [was] not going to apply [that] time." The execution was successfully avoided due to Izzy Sinclair's intervention. (COMIC: By Hook or By Crook)

After the Eighth Doctor was stabbed in the chest by, Izzy implored him to regenerate, but the Doctor told her that the Master had used a certain energy that inhibited the regeneration. The Doctor was healed by Kroton when he became the controller of the Glory. (COMIC: The Glorious Dead)

After being wounded in a duel with Sebastian Grayle, the Eighth Doctor initially asked Charley Pollard if he had "changed", but was assured that he looked no different. (AUDIO: Seasons of Fear)

When Charley stabbed the Eighth Doctor when he was under the influence of Zagreus, the Doctor resisted the regeneration due to his desire to die. After talking with manifistations of his three predecessors, the Doctor was able to undo his death by surrendering to the forces of Anti-time that empowered Zagreus. (AUDIO: Zagreus)

When his memory began to fail, the Eighth Doctor took it as a sign that he would regenerate soon. (PROSE: The End) Before the Last Great Time War, the Doctor could feel his regeneration coming. (PROSE: Museum Peace) Cardinal Ollistra threatened to shoot the Doctor on a Gallifreyan Military Moon Base, believing she would have better luck convincing his next incarnation to fight in the Time War. (AUDIO: The Conscript)

Regeneration
"Doctor no more."

- The War Doctor's first words

When the Last Great Time War erupted, the Eighth Doctor refused to fight in the conflict, instead helping out its victims wherever he could. (TV: The Night of the Doctor) In the Fifth Segment of the War, (PROSE: The Stranger) he discovered a woman named Cass trapped aboard an out of control starship, inbound for the planet Karn. He attempted to rescue her from the vessel, but Cass rejected his offer due to him being a Time Lord. He refused to leave her, letting himself die with her as the ship smashed into Karn's surface.

However, he was revived by the Sisterhood of Karn, who offered him the ability to control his regeneration and become the person he needed to be in order to end the Time War. Initially he refused, but after seeing Cass' corpse, on top of the many other tragedies of the Time War, the Doctor's spirit finally broke. Accepting their help, he drank a specially-made formula of the Elixir of Life, and regenerated into the warrior the Time War needed. The new Doctor promptly rejected his name, declaring, as he picked up and donned Cass' bandoleer, "Doctor no more", (TV: The Night of the Doctor) renaming himself "the Warrior" for a time. (PROSE: The Stranger)

Early battles
Sontarans told legends of the Doctor leading the Time Lords into battle, (TV: The Sontaran Stratagem) with soldiers like Gastron serving with "the Doctor of War" on the Skull Moon. (TV: Hell Bent) Likewise, the Daleks became frightened of his mere presence in the war (TV: The Day of the Doctor) and referred to him as "the Predator". (PROSE: Engines of War) During the War against the Daleks, the Doctor also fought the Horde of Travesties, the Army of Meanwhiles and Neverweres, and the Skaro Degradations and their kin. He also faced the Nightmare Child, (PROSE: A Prologue) and made arrangements for it "to never arise and [to] forever be aware of its non-existence". (PROSE: Twice Upon a Time)

With fellow soldier Petrella by his side, the Doctor joined a fleet of Battle TARDISes in an attack against the Daleks, only for the Battle TARDISes to be ambushed by a Dalek weapon. Realising they had been fed intelligence by the Daleks to draw him out, the Doctor headed for Gallifrey to have a word with Rassilon. (COMIC: Ambush)

Along with his twelve other incarnations, the Doctor became trapped in the Void. He helped his other selves to pacify the Type 1 TARDIS responsible for the disturbance, and returned to his own timeline. (COMIC: The Lost Dimension)

Dealing with the Volatix Cabal
The Doctor took on the Squire as a companion, showing her the prose of Marcel Proust during their travels. (COMIC: The Then and the Now) With the Squire, the Doctor led a Shrikefleet against a Plasma-Wheel armada on Vexa, held the line against six Barrage-Leks and routed the exotic plunder at the chronofracture on Borun, and threw down the Heisenberg mutations on Kether Prime. (COMIC: Pull to Open)

After it was rumoured that the Daleks had recruited the Cyclors before they could, the War Doctor was sent by the Time Lords to deal with the situation. (COMIC: Pull to Open) He formed a pact with the Master (COMIC: The Organ Grinder), and the duo went to Veestrax, where they found a wall with the phrase "Exterminhate" on it. Though he originally planned to blow the planet up, the Doctor instead transported part of Veestrax to another part of the universe in order to wipe out three Dalek assault battalions. (COMIC: Outrun)

The Doctor, the Master and the Squire landed on the Overcast homeworld, Golgauth, where the Doctor planned to neutralise the Cyclors. (COMIC: The Then and the Now, The One, The Organ Grinder)

The duo soon encountered the Volatix Cabal, together killing one of its members. (COMIC: The Organ Grinder) After defeating one of the groups, the Doctor was then shocked to see the Master's TARDIS crash land near him, piloted by Alice Obiefune, a woman who claimed to have time travelled from after the War had ended. Alice was captured by mechanic tentacles, which brought her underground to a base of the Dalek mutants. (COMIC: First Rule) The Doctor sent the Squire to save Alice and afterwards the team left in the TARDIS to an Overcaste rebel base.

Using the psychic paper as a test, they succeeded in uncovering a Volatix spy within the group, but were too late in stopping him from summoning a Cyclor to their location. (COMIC: The Organ Grinder) They ran from the Cyclors, and the Doctor soon realised that Alice had stolen the Psilent songbox from him as she fled from the scene. The Doctor and his companions caught up with Alice, who refused to hand over the Songbox. Alice used the Songbox and banished the Cyclors to a higher dimension. Unbeknownst to the Doctor, the Master had attempted to flee in the version of his TARDIS that Alice brought from the future. The Master's actions created a paradox that reacted with the Songbox, which in turn began to collapse timelines, resulting in chronal meltdown. (COMIC: Kill God) The Doctor used the temporal dart that had been inside Alice to reverse its origins, creating the Then and the Now. He placed Alice inside the creature and sent her back to her own time, and then stamped on the Songbox to end the madness. (COMIC: Fast Asleep) The paradox caused the Doctor to forget everything about Alice, the Cyclors, his time with the Master, and what had happened in the month he had been sent to investigate them. (COMIC: Pull to Open, Fast Asleep)

The Doctor was later fighting the Volatix Cabal when the Then and the Now reappeared, bringing with it Abslom Daak, who had been sent by the Eleventh Doctor to fight in the Time War. Recognising Daak, the Doctor stated simply "Oh no." (COMIC: Physician, Heal Thyself)

The Keska incident
The Doctor dematerialised his TARDIS at Omega One as two Time Lords were about to detonate the Dalek's Time Destructor on the Dalek Fleet. The Doctor allowed the Time Lords to return home and detonated the device himself. The Doctor was found in a coma on the planet Keska, and was nursed to health by Rejoice, a native Keskan. He wanted to help the Keskans stop the Taalyens from wiping them out, and constructed a force field to do this. Cardinal Ollistra used power from the Eye of Harmony to drag him back to Gallifrey. (AUDIO: The Innocent)

He was then sent to find Seratrix in the Null Zone with Veklin by Ollistra because he was an expert on the Daleks. He decided to disobey these orders and accidentally entered the Null Zone. He landed on Keska and discovered that the Daleks had helped the Taalyens bypass the force field. He met with an older Rejoice. He discovered that Seratrix wanted to make peace with the Daleks to stop the Time War. (AUDIO: The Thousand Worlds) He tried to tell Seratrix that his work was stupid as the Dalek plan to administer a defensive empire in the Null Zone wasn't possible. He planned to show Seratrix the true Dalek plan, doing this by hacking into the Dalek systems.

Along with the Keskans, they destroyed the Daleks by deafening then, and stopped their plan by detonating the drill early. By this point he had accepted that he was a monster. (AUDIO: The Heart of the Battle)

War criminal
The Doctor destroyed the Annihilator on Vildar, but a Time Lady named Collis, who had been sent to retrieve it, died protecting him from Varga plants. Now deemed dead, the Doctor found himself on Aldriss, the planet of the Technomancers, where they had been reviving dead Time Lords, such as Collis, outraging the Doctor when he found out that the Valdarians were being sacrificed to revive the dead. Discovering that a small part of the Technomancer's masters, the Horned Ones, were also being placed in the revived Time Lords, Collis and the Doctor ran to the Crypt of Non-Time, where the Annihilator resided after the Doctor had used it to wipe itself from time. After Collis died at the hands of the Technomancer leader, Shadovar, the Doctor set the Annihilator off, wiping the Technomacers and the Horned Ones from time. It was this act which Ollistra used to imprison him. (AUDIO: Legion of the Lost)

Placed in an Artron leash, the Doctor went with Ollistra, Jarad and Solex to Asteroid Theta 12. He was also tasked with discovering the purpose of the anima device. When he went to save Jarad, Ollistra accused of him of still keeping his values of his rejected name. He discovered that the Daleks were retro engineering themselves back into Kaleds, in order to get new insights into war. When he discovered the use of the anima device he allowed Ollistra to use it so they could escape. (AUDIO: A Thing of Guile)

Ollistra had programmed the TARDIS to travel into the Neverwhen explosion. There he witnessed the results of the Time Lord weapon. He initially helped a set of soldiers against an aggressor. He saw that time phasing at first hand when he saw Kaleds evolving into Daleks, and Time Lords retro-evolving into Cave Men before the Dark Times. Ollistra caught up with him and told him to dismantle the Neverwhen so that she can use it in conjunction with the anima device to destroy Skaro. Instead, he stopped it from working in the first place. The Doctor attempted to use it to create a state of peace where both Daleks and Time Lords were farmers, but their conflict was so ingrained that the residents of the new timeline still ended up fighting. Ollistra planned to use it along with the Neverwhen to destroy Skaro, but the Doctor modified the Neverwhen so that the experiment would be deemed a failure, as he felt that there was no way to predict the side-effects of Ollistra's plan on the wider universe. (AUDIO: The Neverwhen)

Missions of war
During the year A10%? on the planet Marinus, the Doctor assisted the Voord in setting up a chronic tripwire against the Daleks. After a Dalek flying saucer fell into the trap, and the Daleks onboard turned to dust, the Doctor and the Voords went in to investigate, but not before the leader's Paradox Shield failed and he passed on his leadership and liquid-metallic bodysuit in his last moment.

Inside the downed saucer, the Doctor talked with a Voord named Siatak about how the Time War had caused the Voord to become more formidable beings, and Siatak's fears of the Time Lords reverting the Voords' development in the event they won the war. As his relationship with the High Council was complicated, and due to his inability to make grand promises in wartime, all the Doctor could do was to offer to act as an intermediary for the Voord if the Time Lords were still prepared to listen to him after the war, though this did not stop Siatak from fearing the future. (COMIC: Four Doctors)

Opposing the Dalek Time Strategist
He travelled to Earth to stop the Dalek Agent Lara Zannis from operating the Shadow Vortex. He was initially captured by the Stasi in East Berlin and interrogated by Kruger, and he later escaped with him and went to West Berlin to try to stop it from happening. In order to stop the Dalek invasion he materialised around the vortex and Zannis and took them with him back 45 minutes in time, and landed in her and the machine's past killing her and reasserting the Web of Time. Returning from Earth back to the war he was informed by Heleyna that Ollistra had been kidnapped. (AUDIO: The Shadow Vortex)

He devised a plan to get onto Rovidia to recapture Ollistra from the Sontarans. He was amazed that the Sontarans were able to hold out for six hours against the Dalek time fleet. Using a stealth ship, and dressed as Rovidians, he went to the planet to rescue her. With the help of Kalan he got to the citadel where the Sontarans kept Ollistra. The closer he got to the citadel he experienced the pain of Vassarian during his prolonged regeneration. He couldn't imagine the Sontaran's allying with either the Daleks or Time Lords and realised Ollistra was bait, as they wanted to start a third front in the war. He worked out that it wasn't the Sontarans that were controlling the atron energy but Vassarian, and discovered that he needed some help to stop the Sontarans. He then managed to escape in Vassarian's Battle TARDIS with Ollistra, Kalan and Heleyna. He was pushed off the TARDIS by Heleyna in order to kill him. (AUDIO: The Eternity Cage)

Ollistra used the TARDIS' transmat to get him back on the ship. He had to find Heleyna through the ship, avoiding her traps, which included the sabotaging of the ship's Architectural reconfiguration system. He eventually made it to the Eye of Harmony chamber just in time before the Dalek Time Assault Squad arrived in the ship. He used Heleyna's idea of manipulating the reconfiguration system and destroyed the chamber to stop the Daleks. This stopped the Daleks but stranded him in the Vortex. He realised that asking Heleyna to detonate a Dalek Dark Matter bomb would give the TARDIS enough energy to materialise into real time. When they did he tried to save Kalan but he had already died. (AUDIO: Eye of Harmony)

The Doctor and Ollistra were then captured and sent on an escape capture to be picked up by the Daleks. The Doctor avoided capture by flying the capsule to Beltox. Whilst there he met Schandel, who wanted to interview him as a war hero. The Doctor did not like this, especially when he learnt that the Daleks were going to arrive. He warned the locals in Fergil and helped to defend them by augmenting their climate control system to become a shield. Eventually, the Doctor realised he could trick the Daleks into thinking that he had tremendous firepower, and blew them up when they got arrogant. He then took Schandel's time ship to its next destination. (AUDIO: Pretty Lies)

Arriving at Grend, he asked Rosata Laxter to help him locate the Lady of Obsidian, which he realised was Leela. He went into the Obsidian Nebula to find her. When he had to escape from The Unlived, his escape pod was taken by Leela's forces. She couldn't remember him properly due to her death by the Disruptor Dalek, but the Doctor tried to help her remember but this caused her more pain. Leela showed him the breach that cause the Unlived to get into the universe, he decided to close it. (AUDIO: The Lady of Obsidian)

He couldn't get back to Gallifrey but there was a massless planet that was fractal in nature. He thought that there was a visual disturbance that was causing them to perceive it. He thought that destroying the Enigma was like fighting poetry with a battleship. He went to the origin of the Enigma. He thought that the Enigma had rewritten time to replace the Time Lords with Daleks. When he left the TARDIS in the Enigma's dimension he couldn't feel anything that he could comprehend and that the time War never happened. The Doctor realised that it was using emotions to contact Leela. The Doctor theorised that it was the contact with Leela that stopped the destruction of Gallifrey. He managed to get the TARDIS to absorb energy from the Daleks weapons. He wished that the Enigma should kill both races to stop a Time War. (AUDIO: The Enigma Dimension)

Final fights
The Doctor travelled back to Gallifrey during the First Segment of the War to stop the Daleks from wiping out Gallifreyan children. He went to the munition factory inside the Mountain of Serenity and saved Rojan, Gahnna and several other children from a Dalek attack, but Senior Tahl chose to sacrifice himself to save the children from the Daleks. Entrusting Rojan with the children's safety, the Doctor left in his TARDIS. (PROSE: The Stranger)

The Doctor opposed Ollistra's idea to recruit the Great Vampires into the Time War. To this end, he travelled to Space Station Zenobia II to prevent Councillor Voltrix from opening a rift into the Vampires' universe, but his protests fell on deaf ears. (COMIC: The Bidding War)

Late in the War, the Doctor was ordered by Lord President Rassilon to find, who had fled from the War, but the Doctor couldn't find any trace of his old enemy. (PROSE: Engines of War)

Events in the Tantalus Eye
Leading a flotilla of Battle TARDISes to the Tantalus Eye to engage the Daleks, the Doctor crashed on Moldox after evading his TARDIS out of the way of a Dalek stealth ships ambush that wiped out the flotilla. On Moldox, the Doctor met Cinder, and used her help in investigating a Dalek base, where he found Temporal Weapon Daleks, a new breed of Dalek that possessed weaponry capable of removing living creatures from existence, and discovered that the Eternity Circle of Daleks were building a De-mat weapon in a plan to wipe Gallifrey from history.

The Doctor took Cinder to Gallifrey in order to warn the Time Lords of the Daleks' plan. The Doctor told Rassilon and the High Council of the Daleks' plan, and Rassilon decided to use to Tear of Isha to wipe the Dalek presence from the Eye, killing all other life in the area in the process. The Doctor was against this plan, so Rassilon had him and Cinder thrown into a prison cell.

With Cinder's help, the Doctor broke free of the prison. Picking up Karlax, who was now was on the verge of regenerating after ambushing the TARDIS, the Doctor and Cinder escaped to the Death Zone in order to find Borusa, whom Rassilon was using as a possibility engine to predict the outcome of battles in the War. After leaving Karlax to recover in the Zero Room, the Doctor and Cinder travelled to confront the Daleks near the Tantalus Eye after disposing of the Tear in the distant future. The Dalek leaders attempted to forcibly convert the Doctor into the prototype of the new Predator Dalek — unable to comprehend that doing so would deprive the Doctor of the very advantages they sought to harness but they were saved when Karlax recovered from his regeneration and tried to escape in the TARDIS, which responded to a program that the Doctor had added that would cause it to home in on a tracking signal implanted in Cinder by the Time Lords. Outraged, Karlax attempted to kill the Doctor, but Cinder jumped in the way of the blast to protect him. In revenge, the Doctor set the TARDIS to leave Karlax behind as it dematerialised, leaving him to be exterminated on board a Dalek command station. Bleeding to death, Cinder died on the floor of the TARDIS.

The Doctor had the opportunity to use Borusa's possibility engine to create an alternate timeline where Cinder survived but knew she would have preferred that he ensure the Eternity Circle of Daleks never existed. The Doctor took Borusa to the Tantalus Eye, the proximity of which gave Borusa the ability to change the timelines to his preference. The Doctor used Borusa to wipe out the Dalek presence from the Eye, thus ending the Dalek plan, but at the price of Borusa's death.

The Doctor then journeyed to Moldox after going around searching for information about how to find the cadavers of Cinder's deceased family, who were all murdered by Daleks and left to rot in the ruins of their own home. The Doctor buried the skeletal remains of Cinder's mother, father and brother along with Cinder's body, and erected a wooden grave marker that bore her real, beautiful human name. After paying his respects to the fallen family, he stood and looked defiantly at the Tantalus Eye. In honour of Cinder's death, the Doctor vowed to put an end to the War once and for all, promising "no more". (PROSE: Engines of War)

Rogue soldier
The day before the end of the Time War, the Doctor went to Skaro and destroyed most of the Dalek Emperor's fleet. Using a stolen gunship, he burned the message "no more" into the Dalek City. (PROSE: The Day of the Doctor)

Last day of the War
After fighting the Time War for "a very long time", (TV: The Day of the Doctor) the Doctor learnt of Rassilon's plan to rupture the Time Vortex and destroy the universe and took it upon himself to end the war. (TV: The End of Time) He was able to breach the Omega Arsenal, a repository of forbidden weapons, and took the Moment, a weapon of ultimate destruction which had developed a sentience and conscience of its own. (TV: The Day of the Doctor)

The Doctor appeared at the fall of Arcadia, (TV: Doomsday) in the midst of an attack by the combined Dalek Fleet of about ten million ships (TV: Dalek) with a "billion billion" Daleks descending on Gallifrey. His presence baited several Daleks away from innocent Gallifreyan refugees fleeing the ravaged city, who became solely concerned with eliminating him, as he used a soldier's gun to inscribe the words "no more" onto a wall as a message to the Time Lords and the Daleks. He then destroyed the group of Daleks with his TARDIS as he left, (TV: The Day of the Doctor) disappearing from Time Lord observation (TV: The End of Time) into the Drylands of Gallifrey, (TV: Hell Bent) leaving only a warning to the Time Lords and the Daleks that the war had carried on "for too long" and he would end the war that day.

Choosing to activate the Moment far away from his TARDIS so that it would not witness the terrible act he was about to commit, (TV: The Day of the Doctor) and acting on a dream he had had in his childhood, the Doctor retreated to the barn he slept in as a child, (TV: Listen) where the Moment's interface manifested into the form of Rose Tyler, a future companion of his, to challenge his use of the weapon and warning him that he would one day count the innocent children on Gallifrey that would be among those killed if he used the weapon.

Upon realising that the Doctor saw no other way to end the Time War than by using it, the Moment created a time fissure that sent him into his future, in order to witness the effects that making such a choice would have upon him. He met with the Tenth and Eleventh Doctors in 1562 England and ended up thrown in the Tower of London by Queen Elizabeth I, posing as a Zygon the Tenth Doctor had been tracking. Not realising that she left their cell door unlocked, the War Doctor placed the calculation to disintegrate the structure of the prison door as a permanent subroutine in the sonic screwdriver, which was completed by the Eleventh Doctor's time. Before they could put the calculations to use, the Eleventh Doctor's companion, Clara Oswald, opened the unlocked door, freeing them, but they were unable to escape from the Queen.

Elizabeth, revealing her masquerade, showed the Doctors that the Zygons were placing themselves inside stasis cubes so that they would awaken when Earth became a more advanced place to invade. Realising the Black Archive, which the Zygons had taken over in Earth's future, was impenetrable from the TARDIS, the War Doctor deduced a way in, which involved the Eleventh Doctor ordering McGillop to place the stasis cube, Gallifrey Falls No More, inside the Archive before the Zygon attack. The three Doctors and Clara froze themselves inside the cube, where they fought a Dalek and blasted their way into the Black Archive. The Doctors wiped the minds of Kate Stewart, Osgood, McGillop, and the Zygons impersonating them, forcing them to cancel the detonation of a nuclear weapon beneath the Archive and begin peace talks between the humans and Zygons, as neither side knew which ones were real or fake.

Feeling that the regret his future selves felt for destroying Gallifrey had led them to save many worlds, the War Doctor, after speaking with Clara, decided to activate the Moment. However, the Tenth and Eleventh Doctors joined him to press the button, finally forgiving him and themselves for the atrocity they committed, until Clara insisted that they find another way. After the Moment showed them a projection of the suffering of the Time War, the Eleventh Doctor decided not to use the Moment, and came up with a plan that involved saving Gallifrey.

Informing the General of their plan, the Doctors were joined by their nine other incarnations, as well as a future incarnation, to freeze Gallifrey in a pocket universe. The General was sceptical of their plan but gave the order when the Dalek army increased their attack. All thirteen Doctors managed to move Gallifrey and destroyed the Daleks. Meeting up at the National Gallery, the War Doctor voiced his uncertainty of their success to the Tenth and Eleventh Doctors, but took solace in the fact they may have "failed at the doing the right thing, as opposed to succeeding in doing the wrong". He was pleased that he could call himself "the Doctor" once again, even if it was for mere moments. Reminding himself that he will forget his attempt to save Gallifrey due to the timelines being out of sync, the Doctor bade farewell to Clara and his future selves and left in his TARDIS. (TV: The Day of the Doctor)

Death
"I hope the ears are a bit less conspicuous this time."

- The War Doctor's last words

As soon as he set the TARDIS for flight, the Doctor noticed that his regenerative process had triggered automatically. Commenting on how his body was "wearing a bit thin", the Doctor mused how he hoped his next incarnation's ears would be "a bit less conspicuous", as he regenerated with a peaceful smile on his face. (TV: The Day of the Doctor)

His successor would once again use the name "Doctor" after he regenerated, (TV: Rose) but, due to the timelines being "out of synch," he lost all memory of what had happened at the end of the Time War, (TV: The Day of the Doctor) believing that he had destroyed Gallifrey, and that he was the last of the Time Lords, (TV: The End of the World, Dalek) leaving him and his two successors with an intense hatred of their war incarnation, (TV: The Name of the Doctor, The Day of the Doctor) while the Time Lords hailed him a war hero. (TV: Hell Bent)

Post-mortem
While the Doctor made no secret of his part or actions in the Time War, (TV: Rose, Dalek, Doomsday, The Sound of Drums, The Doctor's Wife) he instead chose to reject who he was during the war, considering that incarnation to be "the one who broke the promise" of his chosen name as "the Doctor" (TV: The Name of the Doctor, The Day of the Doctor) However, despite his attempts to forget, the Doctor occasionally thought about his war incarnation, (PROSE: Nothing O'Clock) and even confided his existence to River Song. (TV: The Husbands of River Song)

When the Ninth Doctor's Sin-Eater became conscious due to the Doctor's telepathic nature, it mutated to show the War Doctor's face, among other incarnations, straining against its body. (COMIC: Sin-Eaters)

When the Eleventh Doctor first examined his new face in a mirror, he heard the voice of his war incarnation challenge his claim of only having eleven faces. (PROSE: The Day of the Doctor)

When the Then and the Now attempted to ingest the Eleventh Doctor's timeline, the Doctor briefly retro-regenerated back into the War Doctor. Being an "X-rated" period of his life that the Doctor resisted, this halted the ingestion. (COMIC: Outrun)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations appeared inside it to defend themselves as well, though the War Doctor decided not to defend himself, leaving it to the Eighth Doctor to defend his actions in the Time War. When the Eleventh Doctor began to deduce Sondrah's true identity, the past Doctors faded away as Oscar Wilde interfered with the Nexus. (COMIC: Dead Man's Hand)

When the Eleventh Doctor entered his Time stream to save Clara Oswald, he encountered his war incarnation, who he described as "[his] secret". As the Doctor carried an unconscious Clara away, the War Doctor turned around and watched them with a sombre stare. (TV: The Name of the Doctor)

Ultimately, the Doctor remembered the true result of the Time War. After reassessing the War Doctor, his tenth incarnation declared that the war incarnation had been "the Doctor more than anybody else", while the eleventh incarnation noted that the War Doctor was "the Doctor on the day it wasn't possible to get it right". They forgave their war incarnation and themselves for the atrocities they committed and honoured him by addressing him as Doctor again.

Later, as the Eleventh Doctor dreamed about his search for Gallifrey, he included his war incarnation alongside his ten other predecessors in the dream, further showing his acceptance of the War Doctor. (TV: The Day of the Doctor)

While the Twelfth Doctor was on the planet Eed'n, he became infected with pollen from the plants and possessed by the entity that controlled all of Eedin's plants, but he was able to fight off the possession by summoning the memories of his past incarnations, such as the War Doctor. (COMIC: Petals)

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

Alternate timelines
When the Cybermen allied with Rassilon to take over history, the War Doctor fought the Time War against the Cybermen, ultimately detonating the Moment inside the barn as it was surrounded by Cybermen. (COMIC: Prologue: the War Doctor)

Full of self-doubt and self-loathing, the War Doctor not only thought himself unworthy of the name of "the Doctor", (TV: The Day of the Doctor) dispatching the moniker immediately after regeneration (TV: The Night of the Doctor) in favour of the title of "Warrior", (PROSE: The Stranger) but also of any identity at all, eventually leaving it to others to choose how they wished to address him. (PROSE: Engines of War) He would show extreme bouts of anger if anyone called him by his former title, showing that the things he did during the War made him believe himself unworthy of such a title. He often referred to himself as a "monster".

He acknowledged that the Time War had changed him, (PROSE: The Stranger) and made him unable to make the same promises his previous incarnations could, (COMIC: Four Doctors) and also reflected how he was a lesser man than his successors, having become great men from the guilt they had for his actions, and viewed it as his privilege to light the flame that forged their greatness. (TV: The Day of the Doctor)

Convincing himself to believe he was a different man with different ideals to his predecessors, the War Doctor was prone to bouts of anger and rage, roaring in grief for Cinder and the Fifth Time Lord Battle Fleet, and picking up Karlax by the throat and hoisting him in the air when provoked. (PROSE: Engines of War) He could also be stern, as indicated by his dislike for childlike vocabulary, considering the fact that the Eleventh Doctor used such words as a proof that he was ashamed of being a grown-up. (TV: The Day of the Doctor) His personal conflict about the Time War was so great that he considered it easier to view himself as a different man to the Doctor, recognising that his previous selves would hate what he had become whereas he chose to recognise the necessity of what he had to do and not waste time recriminating himself for his actions (AUDIO: The Neverwhen).

Due to his advanced age, the War Doctor was cagey and cranky, tired of the suffering and anarchy the Time War had caused, having lost the will to survive beyond the war and his self-beliefs, (TV: The Day of the Doctor) but still maintained a whimsical charm, addressing the TARDIS as "old girl", not wishing to get his boots dirty in case he stepped in the TARDIS and made a mess, (PROSE: Engines of War) speaking kindly to Clara Oswald, (TV: The Day of the Doctor) laughing at jokes he accidentally made, (PROSE: The Stranger) and reassuring Siatak that he would act as an intermediary between the Time Lords and the Voords when the war ended. (COMIC: Four Doctors) He berated his future selves for pointing their sonic screwdrivers as weapons, calling the screwdriver a "scientific instrument, not [a] water pistol", though later found himself wielding his screwdriver in a similar fashion against an attacking Dalek. (TV: The Day of the Doctor)

The Doctor also displayed a confident recklessness, as he considered politely asking a Dalek to take him and Cinder prisoner to infiltrate Andor, approached a Dalek flying saucer with the intention of walking onboard instead of sneaking on, decided his way around the Dalek saucer with "Eeny, meeny, miny, moe", and confidently walked out to meet the Eternity Circle after asking some Dalek soldiers to "take [him] to [their] leader". (PROSE: Engines of War)

Unlike his other incarnations, the War Doctor endorsed the use of weapons, allowing Cinder to bring her gun aboard the TARDIS, using a Temporal Cannon to defend himself from a Dalek, (PROSE: Engines of War) and wielding a gun during the Fall of Arcadia to carve an inscription on a wall. (TV: The Day of the Doctor) However, he was known to enter battles unarmed in the War, (TV: Hell Bent) berated Cinder for pointing her gun at him when he showed no hostilities, (PROSE: Engines of War) and had a reluctance to have weapons aboard the TARDIS, owing to the fact she didn't like them. (TV: The Day of the Doctor; PROSE: Engines of War)

Also contrary to his other incarnations, the War Doctor did not take on companions unless it was absolutely necessary, or they proved to be capable of defending themselves, as he feared his inability to protect them, instead taking comfort from the sound of the TARDIS control console. (PROSE: Engines of War)

Similar to his second and seventh incarnations, the War Doctor was also painfully aware of the need to see the "bigger picture". He knew it would be selfish to undo Cinder's death instead of stopping the Daleks, (PROSE: Engines of War) and that it was entirely proper to sacrifice his people if it would save the universe. (TV: The Day of the Doctor) When his eleventh incarnation questioned him in their time stream on the actions that he had to make during the war, the War Doctor responded by defending those actions, stating he had "no choice" and that he did what he did "in the name of peace and sanity." (TV: The Name of the Doctor) Despite focusing on the grand scale, the Doctor still had his limits, being appalled by the depths Rassilon and the High Council had sunk to in the war and was both outraged and disgusted when he found out Rassilon had retro-evolved Borusa into a possibility engine. (PROSE: Engines of War)

The Doctor could react mercilessly to a situation; boiling Kaled mutants alive, attempting to subject a Dalek to a Temporal Cannon, leaving Karlax to his own death after Cinder's murder, (PROSE: Engines of War) and unceremoniously mowing down attacking Daleks with his TARDIS. (TV: The Day of the Doctor) The War Doctor was also willing to abandon others if they provided no tactful advantage, almost leaving Dalek prisoners to their fates until Cinder convinced him to liberate them, (PROSE: Engines of War) and showed some delight at Daleks being killed by a chronic tripwire. (COMIC: Four Doctors)

However, he believed that mercy was a strength and valued life above all else, arguing with Rassilon about closing the Tantalus Eye, as the result would be genocide on the lives within the Tantalus Spiral in the ensuing destruction, (PROSE: Engines of War) and also hesitated to destroy Gallifrey when thinking of the innocent children he would kill as a result. (TV: The Day of the Doctor)

Though the Time War caused the War Doctor to be addled with much regret, sadness, and weighted guilt, he also managed to be cheerful and compassionate with a few moments of witty humour and sarcasm, telling Cinder they had "places to go, [and] people to see" while joyfully sneaking into Andor, joked that the Eternity Circle of Daleks weren't a circle, drawing an imaginary circle in the air with his finger to demonstrate his point, (PROSE: Engines of War) and, upon having his head threatened by Lord Bentham for apparently bewitching the Queen, the Doctor quipped that it was Bentham's "lucky day" for unknowingly stumbling upon three incarnations of the Doctor at once. (TV: The Day of the Doctor)

The War Doctor believed in second chances, taking Cinder on as a temporary companion after she threatened him with a gun, and rescuing Karlax from the ruins of his Battle TARDIS to assist in his regeneration. He also considered books, marshmallows and Earl Grey tea to be amongst the "finer things in life", along with the view from the banks of the Rhine, the ash oceans of Astragard and the pleasure of Cleopatra's court. He still found the Tantalus Eye to be breathtakingly beautiful, remembering his time there in his fourth and eighth incarnations. (PROSE: Engines of War) He also had fond memories of Marinus, describing it as being a "lush world of many ecosystems." (COMIC: Four Doctors)

While he was willing to frighten them to ensure they understood the seriousness of the war, the Doctor was highly protective of young children. He encouraged Gahnna by telling him that his fear pushed him to achieve, (PROSE: The Stranger) and hesitated to use the Moment when it pointed out that he would slaughter children upon activating the weapon. (TV: The Day of the Doctor)

Despite being more concerned with the Time War than defending Earth and the rest of the universe, the War Doctor still cared and was willing to help out when necessary. He aided his other incarnations in stopping the Type 1 TARDIS from consuming the universe, (COMIC: The Lost Dimension) and helped the Tenth and Eleventh Doctors in defeating a Zygon plot, coming up with the idea that let them get into the TARDIS-proofed Tower of London and helping them wipe everyone's memories to ensure peace. He was also shown to be pleased that the outcome of the situation was diplomacy rather than destruction, showing that he still desired peace. Upon learning that he had a chance to save Gallifrey rather than destroy it, the War Doctor became elated, blowing a joyful kiss to the Moment, and took solace in restoring his right to be called the Doctor. The Tenth and Eleventh admitted that even though the War Doctor chose to abandon their name, he never abandoned the promise being "The Doctor" stood for. (TV: The Day of the Doctor)

The War Doctor was critical of his tenth and eleventh incarnations, finding them to be very childish and ashamed to be grown up. He was particularly critical of the Eleventh Doctor, disliking his use of the word "timey wimey" and his inability to talk without flapping his hands around, while also criticising the Tenth Doctor's footwear and the Eleventh Doctor's bow tie. After watching them broker peace between UNIT and the Zygons, his opinion of them changed for the better, as he described them as "extraordinary men" to the Moment. When leaving for his own time stream, he considered meeting his future selves "an honour and a privilege", a compliment they returned to him. (TV: The Day of the Doctor)

While the General considered him a "madman," and a "mad fool" at that, Clara Oswald, when distinguishing him from his other incarnations, described the War Doctor as "the warrior." (TV: The Day of the Doctor) Rojan, after seeing the War Doctor's elderly face, felt that the War Doctor "wasn't a man who found much joy in life." (PROSE: The Stranger)

Upon noticing his regeneration beginning, the Doctor held no qualms about regenerating, noting how old he had grown, hoping his successor's ears would be "less conspicuous", and facing the end with an immense grin on his face in his last moments. (TV: The Day of the Doctor) However, due to the timelines not being synchronised, the War Doctor was believed to have destroyed Gallifrey, committing genocide against the Time Lords and the Daleks. As such, the Doctor's future incarnations kept him a secret from others. As such, the War Doctor's memory was known to stare sombrely in the Doctor's time stream, (TV: The Name of the Doctor) not even defending his action to Es'Cartrss in the T'keyn Nexus. (COMIC: Dead Man's Hand)

Habit and quirks
The War Doctor made a habit of incorporating "no more" into his dialogue. (TV: The Night of the Doctor, The Day of the Doctor; PROSE: Engines of War; AUDIO: The Eternity Cage; COMIC: Ambush) He also made a habit of uttering "damn it", usually when things did not meet his satisfaction, (PROSE: Engines of War) and justifying his actions as being done in "the name of peace and sanity." (TV: The Name of the Doctor; COMIC: First Rule, Fast Asleep)

Much to the confusion of his fellow Time Lords, the Doctor was prone to making reference to Earth idioms and phrases. (AUDIO: The Innocent)

The War Doctor would often stand with his arms folded behind his back. (TV: The Day of the Doctor; PROSE: Engines of War) When standing between two people engaging in conversation, such as the Tenth and Eleventh Doctors, the War Doctor would turn his head to face the one that was speaking, even if it meant turning his head back-and-forth. The War Doctor also often uttered the words "Oh, for God's sake!", particularly when frustrated with his two successors childish antics. (TV: The Day of the Doctor)

Skills
Despite his aged appearance, the War Doctor was spritely athletic, being able to outrun a squadron of Daleks ahead of Cinder, and immediately start a daunting climb up a wall afterwards, as well as being capable of dodging a Dalek gunstick at close range. He was also stronger than he appeared, hoisting Karlax in the air by his throat, after marching over the High Council table, in retaliation for using the mind probe on Cinder, and knocked out a Battle TARDIS pilot with a single right hook punch (PROSE: Engines of War)

Though not as quicksilver as his able-bodied successors, the War Doctor paced his thinking, sometimes seeing a hidden solution after much contemplation. (TV: The Day of the Doctor) Though he told Cinder he "was not good with long-term plans", and preferred "winging it", the Doctor had the foresight to surrender to the Daleks, knowing that they would bring him where he wanted to go instead of exterminating him on the spot. He also put a fail-safe on the TARDIS control console that caused his ship to materialise around him in the event that Karlax attempted to hijack it after his regeneration. (PROSE: Engines of War)

The War Doctor was also an impressive marksman, able to inscribe "NO MORE" onto a wall with a gun, and keep his aim despite a battle taking place around him, (TV: The Day of the Doctor) and wield a Temporal Cannon against a Dalek. (PROSE: Engines of War) However, like his predecessors, the War Doctor was better known for his ability to defeat enemies without employing weapons, though rather than show his enemies mercy, he would kill them outright, as indicated by Gastron. (TV: Hell Bent)

Much like his fourth incarnation, the War Doctor could judge a person's character quickly, immediately recognising that Cinder wasn't a murderer, and could assess his surroundings with ease, easily determining that the power pack of Cinder's makeshift gun was empty and the weapon useless.

Due to his third incarnation watching stunt pilots with the Brigadier, the War Doctor was able to pilot his TARDIS through a series of manoeuvres with ease.

The War Doctor could understand Dalek writing, to a degree at least, and was skilled at hacking into the Daleks' databanks. (PROSE: Engines of War)

Appearance
This incarnation of the Doctor originally had a stern and determined face, green-brown eyes and messy brown hair following regeneration. (TV: The Night of the Doctor) He originally went clean shaven, (COMIC: Ambush) but eventually grew a brown Van Dyke beard. (COMIC: The Lost Dimension)

However, after spending "a very long time" fighting in the Time War, (TV: The Day of the Doctor) he became jaded and tired, with his beard having gone grey and pronounced wrinkles on his craggy, careworn face, resembling a man in his seventies. (TV: The Name of the Doctor; PROSE: Engines of War) However, Clara noticed his eyes were younger than those of his future selves, in that they were more hopeful. (TV: The Day of the Doctor) His hair colour turned largely into a deep silver, which he slicked up in peaks at the top of his head. (TV: The Name of the Doctor)

His distinctive, deep voice also became well-known throughout people involved or aware of the Time War. (AUDIO: Pretty Lies)

The War Doctor's aged appearance led his eleventh incarnation to jokingly codename him "Granddad." (TV: The Day of the Doctor) Rojan felt the War Doctor looked like he "had been living rough for a long time." (PROSE: The Stranger)

Clothing
The War Doctor wore a distressed leather overcoat, a frayed scarf knitted in a herringbone pattern, (TV: The Name of the Doctor) and a dark green-brown velvet waistcoat with golden buttons, which had a fob chain attached to it. He also wore aged trousers, a box-frame belt with several fastener pins and studded pinholes, and combat boots adorned with weathered gaiters, which had a few buttons missing. (TV: The Day of the Doctor)

His oldest article of dress was a bandolier across his left shoulder, taken off the body of Cass mere seconds after his regeneration was finished. (TV: The Night of the Doctor) He housed his sonic screwdriver in the bandolier, securing it in a pocket that rested on the far left side of his chest. (TV: The Day of the Doctor)

Behind the scenes

 * John Hurt, aged seventy-three when he first appeared on-screen, is the oldest actor to portray the Doctor upon their debut appearance. The second oldest are William Hartnell and Peter Capaldi, who were both fifty-five years old when they made their debut appearances in 1963 and 2013 respectively (with Capaldi being several months older than Hartnell).
 * Strax describes this incarnation of the Doctor as having "the look of a battle-hardened warrior" in Strax Field Report: The Doctor's Greatest Secret.
 * This incarnation of the Doctor is never named during The Night of the Doctor itself but is described as the War Doctor in the end credits and on the official BBC website . John Hurt is listed as one of the actors playing "The Doctor" in the end credits of The Day of the Doctor and is billed as "The Other Doctor" in Radio Times and the scripts (DWMSE 38). His Character Options action figure is labelled "The Other Doctor," and his Character Options sonic screwdriver toy is labelled "the Other Doctor's Sonic Screwdriver." The subtitles on The Day of the Doctor refer to him as "Old Doctor".
 * Additionally, in-universe, it is mentioned that the War Doctor rejected the name of the Doctor, despite others referring to him as such, though, for a time, it was never actually established by what name or title he used to refer to himself. During Engines of War, he informs his new companion Cinder that he was once referred to as the Doctor and leaves it up to her how she addresses him, asking her fellow survivors to simply call him "John Smith" to avoid revealing his true nature as a Time Lord. In The Stranger, he revealed he went by the name "the Warrior" for a time, establishing his true title.
 * Though John Hurt was seventy-three when he debuted as this incarnation of the Doctor, special effects were used to blend archive material of the actor from earlier in his life to depict the War Doctor, in a reflection, as looking like a younger John Hurt immediately after the Eighth Doctor's regeneration. The archive image for the young War Doctor was from the BBC's 1979 TV series Crime and Punishment, episode one, in which John Hurt (circa 39) portrayed Rodion Raskolnikov (REF: DWMSE 38). The BBC itself later revealed which shot it was. P03gywm4.jpg
 * According to Emma Campbell-Jones, Paul McGann played the newly-regenerated War Doctor in the scene where he takes Cass' bandolier after the regeneration. This makes McGann the second actor to technically play two incarnations of the Doctor since Sylvester McCoy briefly played the Sixth Doctor for the regeneration sequence in Time and the Rani after Colin Baker refused to take part.
 * The War Doctor is the only incarnation of the Doctor to be introduced retroactively, initially existing to serve as a supporting character. All of his appearances predate future incarnations of the Doctor that already debuted, and he shared his screen time with later versions of himself, meaning he never had a distinct televised era as the latest incarnation to exist at the time of his own debut. However, he was given a debut through his own range of audio stories, where the character was now explored as the main protagonist rather than being juxtaposed with later incarnations of the Doctor.
 * The War Doctor was the first among the incarnations of the Doctor introduced in the BBC Wales-produced series of Doctor Who to appear in Big Finish Productions.
 * He is the only incarnation whose era's version of the Doctor Who theme is featured only in audios.
 * The War Doctor was dubbed in Portuguese by Isaac Bardavid and in German by Fred Maire.
 * He bears the sad distinction of being the Doctor whose actor passed away in the shortest amount of time after his debut, as John Hurt incurred an on-and-off bout with pancreatic cancer in the years to follow his appearances in the television series and audio stories, succumbing to it in early 2017.
 * The War Doctor's existence and numberless designation was a workaround in response to the lack of Christopher Eccleston's participation in the 50th-anniversary special. Since the Eighth Doctor had not been shown regenerating into the Ninth Doctor, it left the door open for another incarnation of the Doctor to theoretically exist between the two. As such, Steven Moffat appealed to John Hurt to take up the role because of his famous reputation among British actors, and he also liked the concept of a "mayfly Doctor" who has a short amount of time in existence in the television series before serving their purpose. This caused a permanent disruption in the numbering of the Doctor's incarnations and ultimately accelerated the timetable on his regeneration cycle to be dealt with when Matt Smith left the series.
 * When the War Doctor's costume was initially added to the display of Doctor outfits in The Doctor Who Experience, the bandoleer was incorrectly displayed over the right shoulder instead of the left.
 * He placed last in the first popularity poll where he was included among choices of favourite incarnation of the Doctor taken by Doctor Who Magazine, not because he was disliked, but because his debut was so recent and sparse in the television series that he was overshadowed, predating the production of his audio adventures and many new stories to continue fleshing him out prior to the events of his regeneration.
 * The time period between the broadcasts of the War Doctor's incoming and outgoing regeneration scenes is the shortest of all the Doctor's incarnations. His regeneration from the Eighth Doctor (The Night of the Doctor) and his regeneration into the Ninth (The Day of the Doctor) were broadcast just nine days apart.
