War Doctor

Originally young and robust, the War Doctor set upon the warrior path for which he had been intended, and disavowed the name of "the Doctor". Though the Time Lords and Daleks continued to refer to him by that name, he was also referred to as "the Renegade" by Lady Priyan and "the Warrior" by Clara Oswald.

After becoming old and tired of battle 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 later selves, his mind was opened to a heroic way to end the Time War in lieu of the deadly alternative he was going to enact.

Knowing he could unite with former and future Doctors in force, the War Doctor helped to save Gallifrey from destruction, although he was not able to retain these memories. Because of this, his later incarnations disowned him, believing him to have destroyed Gallifrey. Only the Eleventh Doctor retained the memories, and eventually remembered him as the man who saved Gallifrey, restoring the War Doctor as an embraced and respected incarnation.

After over 100 years of battling in the Last Great Time War, (PROSE: Engines of War) this incarnation eventually regenerated into a younger form due to advanced old age after he had helped save Gallifrey and reclaimed his name.

Near misses
The Eighth Doctor nearly regenerated after being stabbed in the heart by Charlotte Pollard to save him from Rassilon's control, but he was healed by the energies of anti-time controlling his body. (AUDIO: Zagreus)

He nearly regenerated again after his chest was crushed by a sandbag, but he was saved due to one of his hearts having been transplanted into Sabbath, giving him a link to life that allowed his body to heal on its own. (PROSE: Camera Obscura)

Foreshadowing
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)

Post-regeneration
When the Last Great Time War erupted, the Eighth Doctor managed to avoid the conflict, helping out its victims wherever he could. Eventually, as the war grew in scope and violence, 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 when his Time Lord heritage was revealed. The Doctor, however, refused to abandon Cass on the starship, 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 into the warrior the Time War needed. The new Doctor promptly rejected the name of "the Doctor", declaring, as he picked up and donned Cass' bandolier, "Doctor no more". (TV: The Night of the Doctor)

Fighting in the Time War
The Sontarans told legends of the Doctor leading the Time Lords into battle. (TV: The Sontaran Stratagem) Likewise, the Daleks became frightened of his mere presence in the Time War, (TV: The Day of the Doctor) and referred to him as "the Oncoming Storm", (TV: The Parting of the Ways) and "the Predator". (PROSE: Engines of War)

During the War, the Doctor fought against Daleks, the Nightmare Child, the Horde of Travesties, the Meanwhiles and the troops of Neverwere, the Skaro Degradations and their kin, (PROSE: A Prologue) and was ordered by Rassilon to find, who had fled from the War. (PROSE: Engines of War)

Events in the Tantalus Eye
Four hundred years into the War, when the Doctor was a hundred years or more into this incarnation, the Doctor led a flotilla of Battle TARDISes to the Tantalus Eye to engage the Daleks. Dalek stealth ships appeared out of the Time Vortex and wiped out the flotilla, but the Doctor moved his TARDIS out of the way of the main attack and crashed on Moldox. 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, 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, who 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 on Tantalus 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 told the Doctor, "My life in exchange for billions of others, I'll take those odds," before dying 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)

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 plans, 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, in the midst of an attack by a fleet of at least ten million Daleks descending on Gallifrey. (TV: The Last Day) 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)

Choosing to activate the Moment far away from his TARDIS so that it would not witness the terrible act he was about to commit, the Doctor entered an old, rundown barn, 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 were 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, 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 the their plan, the Doctors were joined by the nine other incarnations of the Doctor, as well as a future incarnation, to freeze Gallifrey into a Stasis cube. Meeting up at the National Gallery, the War Doctor voiced his uncertainty of their success to the Tenth and Eleventh Doctors, but took solacing in the fact they may have "failed at the doing the right thing, as opposed to succeeding in doing the wrong". 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
As soon as he set the TARDIS for flight, the Doctor noticed that his regenerative procress had triggered automatically. Commenting how his body had worn "a bit thin", the Doctor mused how he hoped his next body's ears would be "a bit less conspicuous", as he changed into his next incarnation with a peaceful smile on his face. (TV: The Day of the Doctor)

Legacy
While the Doctor made no secret of his actions in the Time War, (TV: 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, even though he did not like to. (PROSE: Nothing O'Clock)

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)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, all of his previous incarnations appeared inside it to defend themselves as well. Although the War Doctor was there with the others, he was the only one not to defend his name. Instead, the Eighth Doctor had to defend what the War Doctor had done in the Time War and all he did to avoid it. (COMIC: Dead Man's Hand)

Ultimately, the Doctor remembered the true result of the Time War. After reassessing the War Doctor, his tenth incarnation declared that this 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". As the Eleventh Doctor later dreamed about his search to find Gallifrey, wherever all his incarnations had sent it, the dream included the war incarnation alongside all of his other selves. (TV: The Day of the Doctor)

Personality
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) but also of any identity at all, often leaving it to others to choose how they wished to address him. (PROSE: Engines of War) He also reflected how he was a lesser man than his successors, having became great men from the guilt they had for his actions. (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 was also 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)

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) and speaking kindly to Clara Oswald. 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 met 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) though he 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 questioned by his eleventh incarnation 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 mowed down attacking Daleks with his TARDIS. (TV: The Day of the Doctor) The War Doctor was also willingly to abandon others if they provided no tactful advantage, almost leaving Dalek prisoners to their fates until Cinder convinced him to liberate them. 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 ensuring 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 moments of witty humour and sarcasm; He told 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, quipped back "this has all the makings of your lucky day," as Bentham had unknowingly stumbled upon three different 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. (PROSE: Engines of War)

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 the Tenth and Eleventh Doctors in defeating the Zygon plan, coming up with the idea that let them get into the TARDIS-proofed Tower of London and helping them wipe everyone but Clara's memories. He was also shown to be pleased that the outcome of the situation was peace 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 kiss to the Moment, and took solace in restoring his right to be called the Doctor. (TV: The Day of the Doctor)

The War Doctor was critical of his tenth and eleventh incarnations, the eleventh in particular, disliking his use of the word "timey wimey" and his inability to talk without his flapping his hands around, while also critising 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. (TV: The Day of the Doctor)

Upon noticing his regeneration beginning, the Doctor held no qualms about regenerating, noting how old he 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 synchronized, the War Doctor was believed to have destroyed Gallifey, committing genocide against the Time Lords and the Daleks. As such, the War Doctor's memory was known to stare somberly 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, for which he was mocked by the Moment for. (TV: The Night of the Doctor, The Day of the Doctor; PROSE: Engines of War) He also made a habit of uttering "damn it", usually when things did not meet his satisfaction. (PROSE: Engines of War)

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 encaging 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. (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. He was also 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 failsafe 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 inscription "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) He was also able to wield a Temporal Cannon against a Dalek. (PROSE: Engines of War)

Much like his fourth incarnation, the War Doctor could judge character quickly, immediately recognizing that Cinder wasn't a murderer, and could asses his surroundings with ease, easily determining that the power pack of Cinder's makeshift gun was empty and the weapon useless. (PROSE: Engines of War)

Due to his third incarnation watching stunt pilots with the Brigadier, the War Doctor was able to pilot his TARDIS through a series of maneuvers with ease. (PROSE: Engines of War)

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
The war incarnation originally had a stern, shaven and determined face with a head of dusty brown hair. (TV: The Night of the Doctor)

However, after spending "a very long time" fighting in the Time War, he became jaded and tired, with pronounced wrinkles on his craggy, careworn face, and weary green-brown eyes. (TV: The Day 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 entirely to a deep silver, which he slicked up in peaks at the top of his head. The elderly War Doctor also allowed himself to grow a bushy white beard and moustache. (TV: The Name of the Doctor)

Clothing
The War Doctor wore a distressed leather overcoat, a frayed scarf knitted in a herringbone pattern, and his previous incarnation's Victorian-style waistcoat, which had a fob chain attached to one of the upper buttons. (TV: The Name of the Doctor) He also wore also 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 WC: 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. His Character Options action figure is labelled 'The Other Doctor'. 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 it is never actually established by what name or title he referred to himself. During Engines of War, he informs his new companion Cinder that he was one 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.
 * 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 apparently lifted from a publicity shot for the 1979 television adaptation of Crime and Punishment.
 * 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. All of his appearances predate future incarnations of the Doctor that already debuted, meaning he never had a distinct televised era as the latest incarnation to exist at the time of his own debut.
