War Doctor

Originally young and robust, the incarnation of the Doctor born into the Last Great Time War set upon the warrior path for which he had been intended. The War Doctor — so named by Alice Obiefune and the Curator — was said to be the Doctor's ninth incarnation, though he disavowed his former name, believing he had broken the promise it represented.

Though most Time Lords and Daleks continued to refer to him by that name, as far as the Doctor was concerned, he had no name. To others, he was the "Doctor of War", "the Warrior", or "the Renegade". Some even called him by his true name, what he was known as before he was the Doctor, as was chronicled in The History of the Time War. 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. According to Gastron, the War Doctor was noted for going into battle unarmed but winning nonetheless, with his unarmed state being the last thing many saw.

In the end, becoming old and battle-weary, and faced with the Ultimate Sanction, the Doctor prepared to use the Moment to end the Time War by committing genocide against both the Daleks and the Time Lords. However, the Moment's sentient interface led him down a different path by letting him view his future first-hand. Teaming up with his future selves, the War Doctor's mind was opened to a peaceful way to end the Time War in lieu of his original plans. Joining with twelve of his other incarnations, the War Doctor was able to save Gallifrey from destruction, and in so doing, became comfortable once more in taking his name. Unfortunately, due to their timeline being out of sync, the Doctor would not remember saving Gallifrey and his next incarnation falsely believed he was the last of the Time Lords.

A day to come
Whilst living in the barn on Gallifrey as a child, the First Doctor was once comforted by a woman who told him that he would one day come back to the barn when he was very afraid, but that fear could make him kind. (TV: Listen)

The First Doctor would occasionally have premonitions of his future incarnations. (PROSE: A Big Hand for the Doctor)

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 his history to stop him from becoming an incarnation that would play a key role in a future conflict. (AUDIO: The Plague of Dreams)

Shortly before his regeneration, the First Doctor was told by the Twelfth Doctor that there would be "a few false starts" before he became him. Not long afterwards, the First Doctor was referred to as "the Doctor of War" by the Testimony Foundation, 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 losing his body to the Time Lords, made a failed attempt to steal a regeneration from the Fifth Doctor. (PROSE: The Velvet Dark)

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)

The Seventh Doctor wondered if any of his successors would have longer legs than him. (AUDIO: Fiesta of the Damned)

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 possess 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)

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 this 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)

The Eighth Doctor nearly regenerated after being wounded by the explosion in the Mukabi laboratory, the associated chemical release eradicating the Fear in his system. (PROSE: Fear Itself)

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)

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 manifestations of his three immediate 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 thought it was a sign that he would soon regenerate. (PROSE: The End)

While working at Phaiton, the Eighth Doctor once pondered on how he'd spend the rest of his lives. (AUDIO: The Satanic Mill)

When talking about the future, the Eighth Doctor noted he would die again, and that one day he would "run out of deaths". (AUDIO: The Gift)

In an attempt to force Artron to operate a machine that would transfer the energy of the Kolstani into him, mortally wounded the Eighth Doctor by shooting him in one of his hearts, warning the Doctor that he would take out the other heart if he attempted to regenerate. However, Artron used the equipment built by the Master to absorb the Kolstani energy into himself, using his new power to heal the Doctor. (AUDIO: Day of the Master)

Before the Last Great Time War, the Eighth Doctor knew he would regenerate again. (PROSE: Museum Peace) During the Battle of Tenacity, Cardinal Ollistra threatened to shoot him 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)

Post-regeneration
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 Fermazzi 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's 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. (TV: The Night of the Doctor) After quickly adjusting to the changes made to his new body, (PROSE: The Day of the Doctor) the new incarnation promptly rejected his name, declaring, as he picked up and donned Cass's bandoleer, "Doctor no more", (TV: The Night of the Doctor) renaming himself "the Warrior" for a time. (PROSE: The Stranger)

The Doctor initially refused to attend Cass’s funeral, but did attend her grave after the ceremony. He searched Karn’s wreckages for weapons, guided by Lithea who used Matrix windows to show him the war front which was approaching Karn, and initially refused to meet the Time Lords who had arrived on Karn. He eventually returned to his TARDIS where he met Cardinal Rasmus and refused to allow the installation of weapons on his ship, reasoning that he shouldn’t force her to change as he had. Learning Commander Sanmar had gone to the heart of Karn with Lithea, he took Rasmus and Ohila down in his TARDIS, arriving just after Sanmar had killed Lithea. He was appalled at Sanmar’s plan to extract the heart of Karn to the Capitol and demanded to speak with her superior, who turned out to be Commodore Tamasan. Tamasan disavowed Sanmar and the Doctor let her be taken by the forces of Karn. He threatened to use the equipment to destroy Karn to take out the war front, now under a Dalek control, with his threat forcing Tamasan to pledge to use a time lock to protect Karn. Ohila truly believed he would do the threat, and conceded he had become what he needed to be. The Doctor departed alone, taking a moment to set to rest trapped souls amidst the Time War wreckage on Karn. After witnessing Karn’s disappearance, the Doctor communicated with Rasmus, telling him he would find his own ways to contribute to the war effort. (AUDIO: Light the Flame)

Working as a free agent
Though becoming involved in the Time War, the Doctor initially remained a free agent, materialising where he pleased and having no direct contact with Rassilon and the Generals of the Time Lords. (COMIC: Ambush) According to the Twelfth Doctor, the War Doctor, during his early days, merely treated the Time War merely as a challenge he had to overcome, (COMIC: The Clockwise War) but most accounts showcased he always knew how dangerous the conflict was. (AUDIO: Light the Flame, et. al)

Answering a distress signal from Lady Valetta, the Doctor worked with her to rescue a group of Tharils being held by Vultarans in a bunker. They joined the mission of second-lieutenant Lorinus who was only aware of Biroc, Valetta’s brother who had been working as a Time Lord spy, being held there. The Doctor arranged events so it appeared he killed the other Tharils as a mercy, secretly using a hacked Vultaran mechasuit to cover their escape whilst he, Valetta, Lorinus and Biroc returned to the Time Lord front lines. He and Valetta got the Tharils aboard his TARDIS and waited for Biroc. He encountered Lorinus, who had just told Tamasan what she thought he’d done, and explained his subterfuge was to protect the Tharils, as now they were believed dead they were not in danger from either side. (AUDIO: Lion Hearts)

The Doctor traced a signal from the Dalek Time Strategist to Atherea and decided to assassinate it, encountering Commodore Tamasan who was on a mission of her own to the planet. After Tamasan’s contact was erased from history, they completed her orders by making contact with a squad of Gallifreyan special forces who had been raised in secret on the planet to fight the Dalek presence there, which was using a time eradicator to assassinate soldiers vital to Dalek losses, turning the tide of recent battles. The Doctor used himself as a distraction to enable the squad to find the Dalek base and discovered the eradicator was one of the Strategist’s engineers, now existing as part of the Vortex and able to see possible timelines.

As the squad took the base following the Doctor’s lead, Tamasan made herself crucial to their victory by destroying the Time Strategist so the eradicator Dalek travelled back to assassinate her earlier in the mission. The Doctor and the squad’s commander followed it and foiled the assassination. The Doctor ripped off the eradicator’s Vortex anchor, causing it to be pulled fully into the Vortex and erased from history, undoing the Daleks’ recent assassinations. In doing so the Doctor also negated the recent battle on Atherea, restoring the Strategist which he resolved to try to kill again when Tamasan arrived with word from Rasmus to congratulate him on undoing the assassinations. (AUDIO: The Shadow Squad)

The Doctor recruited Fey Truscott-Sade from World War II to join him in the conflict.

On the "worst day of the Time War", the Doctor, Fey and the Sisterhood of Karn fought the Daleks and the Morlontoa of the Seventh Sky on the Dorian Nexus. The Doctor constructed a machine that would fire pulses of pure reason at the creature to defeat it. While this was happening, Fey ordered Time Lord Captain Dolios to get the childlike inhabitants of the planet, the Loshann, to a TARDIS. The Sisterhood was then struck by a stream of pure chaos, leading the Loshann to be hit by the spores of the Morlontoa. They were quickly inverted, turned into monsters and attacked. To save themselves and other Loshann on the planet, the Doctor ordered Fey to shoot each of the Loshann. After she did so, the Doctor's machine failed, and the planet would fall anyway, rendering Fey's killing of the Loshann meaningless.

While the planet was saturated by the spores, the Doctor ordered his allies back to his TARDIS. However, Fey instead went to save a child in the wreckage and was touched by the spores before she could return to the TARDIS. Unable to save her or the child, the Doctor could only watch from the TARDIS as Fey melted away. Ohila attempted to comfort him by telling him that he did all that he could, but the Doctor only responded in anger at being addressed as "the Doctor". (COMIC: The Clockwise War)

Based on secret intel, the Doctor and Petrella arrived at a location where they expected to find many Dalek flying saucers. They found them already engaging Voltrix's Battle TARDISes, with the Doctor concluding Voltrix must have received the same intel and ordered an attack. However, as soon as the Daleks detected the presence of the "Predator", the Dalek Supreme ordered the materialisation of new weapons which made short work of the conventional Gallifreyan forces, and instead focused the fleet's attention on the Doctor's TARDIS. Realising the entire battle had been planned out by the Daleks as a lure to try to get at him, the Doctor decided he had no choice but to enter the war in earnest, telling Petrella to set a course for Gallifrey so he could have "a little chat" with Rassilon and begin making a stand with the Time Lords. (COMIC: Ambush)

The Doctor discovered a Dalek plot on Amperica Nova to use nanobots in the entire adult population to make a mirror Gallifrey. He foiled them by using a virus to wipe out the adults, orphaning an entire population. (AUDIO: Consequences)

The Doctor was lured by a distress signal from Davros to the Scaveline system in the first year of the Time War, where he encountered a Time Lord fleet lead by a Commander. Working together they followed the signal to the Gates of Elysium where a Dalek saucer commanded by Davros, was under attack. When a huge swarm of particles indiscriminately destroyed Daleks and Time Lords alike, Davros revealed that he had created a Nightmare Child inspired by the Doctor, and had lured in the Doctor to watch him sacrifice himself to kill it. Branding Davros an idiot, the Doctor attempted to fly his TARDIS towards the destruction to save him however the Time Lord Commander helds his ship back as the gates closed around Davros' ship and the Nightmare Child. (PROSE: The Third Wise Man) The Nightmare Child would be present much later in the Time War, (TV: The End of Time) so the Doctor made arrangements for it "to never arise and [to] forever be aware of its non-existence". (PROSE: Twice Upon a Time)

Fighting on the front line
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 Skull Moon, (TV: Hell Bent) where the Doctor took command of the slaughter, (PROSE: The Day of the Doctor) and became known as the "Butcher of Skull Moon". (TV: Twice Upon a Time) 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) Romana heard of what had become of the Doctor in the Time War from others who had seen him, believing he’d changed for the worse, (AUDIO: Beyond) and later told Leela that the Doctor wouldn’t have such a problem with weapons anymore. (AUDIO: Homecoming)

Overall, the Doctor was responsible for the bloodiest campaign in the history of the known universe, partly known universe, and unknown universe. Rumours spread that he grieved for everyone he killed, yet the man who was once a doctor refused to stop, having decided to he needed to be a soldier until his fighting had put a stop to the War. His fury became the final wonder his billions of enemies ever got to see. After some years of searching, the Doctor was able to return Cass's body to the remains of her family. (PROSE: The Day of the Doctor)

Defeating the Dalek harvesters
Now accompanied by Time Lord agent Veklin, who forced him to use a Battle TARDIS instead of his own TARDIS to make him more controllable, the Doctor rescued an Australian soldier named Albert Brown from the Gallipoli campaign due to his skills being useful to him. The trio went to Carter Baross whose population the Daleks had harvested to make cyborgs. Moments before the Time Lords destroyed the planet they rescued a failed conversion, whose Dalek conditioning was incomplete, Case, as the Doctor believed she could be of use as a weapon.

Immediately after escaping the planet, the Doctor picked up a distress signal he suspected was from a disguised Dalek harvester on a collision course with an inhabited planet, Tharius. He pretended to fall for the trick, connecting the Battle TARDIS to the ship to provide power as the Daleks wanted so they could land on and harvest Thatius, and then used Case to reach the flight deck to set the self-destruct. The Supreme Dalek aboard called his bluff by accelerating the ship's storm drive so its destruction would also wipe out the entire solar system and threatened to kill Veklin and Albert if he didn't stand down. The Doctor briefly stopped his hearts to trigger the Battle TARDIS's self-destruct, which destroyed the storm drive, and had Case stop the self-destruct. With the ship now doomed to crash on Tharius, he devised a plan to use the time drive to take an escape pod back in time a day to evacuate the planet's population first, however Albert was exterminated on the way to the pod and Case was incapacitated by the Daleks. (AUDIO: Saviour)

Crashing a day prior to the collision with Veklin and an amnesiac Case, the Doctor discovered Tharius was in a constant state of warfare and decided to pose as their legendary Warbringer to get the attention of their leaders for an evacuation, much to Veklin's annoyance as she believed they should simply abandon the planet to its fate. After freezing a battle in time using an Artron generator, the Doctor was taken to the leaders of the two factions. They began to doubt him after he refused to kill them to fulfil the Warbringer scripture, (AUDIO: Consequences) however they let him use the generator to temporarily halt the falling harvester ship. Veklin however knocked him unconscious and drove him away from the city, abandoning Case, where Commodore Tamasan arrived in a Battle TARDIS to take him away. Their ensuing argument was interrupted by sudden appearance of Daleks, who knocked the Doctor unconscious so Tamasan carried him into the TARDIS whilst Veklin held them off.

On a carrier ship, Tamasan had him locked on the medical bay. The Doctor escaped and made for Tharius again, arriving back at the Artron generator as Veklin was about to deactivate it. Case arrived with Daleks, having been turned back to her conditioning, and he helped her overcome their control and destroy them. With more Daleks imminently arriving on Tharius, the Doctor reluctantly conceded that whilst he could have saved the people earlier it was not possible now, and deactivated the generator. He escaped the ensuing devastation in the TARDIS with Veklin and Case and returned to Tamasan's ship, refusing to watch the destruction. (AUDIO: Destroyer) Afterwards he explained to Case how he had rescued her and why they had crashed on Tharius. (AUDIO: Saviour)

Solo missions
The Doctor led the final charge at the slopes of the Never Vault, (PROSE: The Day of the Doctor) and arranged for the Advent of Woe to close. (PROSE: Twice Upon a Time) He also met the Time Lord Commander from the Gates of Elysium again, now holding the rank of General, at the Hellion Blaze. (PROSE: The Third Wise Man)

The Doctor was sent by Commodore Tamasan to a research base over a gas giant, where he fell into a dream state due to a chemical weapon being developed there. He forced himself to awake from the dream, in which he'd been the Doctor again travelling alongside Laya Bridge, and was contacted by Tamasan who explained this had served a test for the weapon. Furious at what he'd been put through, and believing the weapon would serve little purpose anyway as Time Lords' imagination made them more susceptible to it than the Daleks, he saw to the base's destruction, ignoring Tamasan's protests. (AUDIO: The Keeper of Light)

The Doctor helped design a new state of the art warship for the Time Lords to give to the Thals, believing it could be the first of a fleet of such ships capable of infiltrating Dalek space, which he named the Temmosus after a figure in Thal history. Discovering the ship's captain, Dylon, was making a deal with the Daleks, he attempted to stop the vessel leaving Time Lord space by deactivating its defences, however the Thal crew pushed on until the Doctor revealed recordings of Dylon's communications with the Daleks. He convinced officer Soolal to mutiny, however crew loyal to Dylon fixed the ship on its course to where he'd arranged to rendezvous with the Daleks. At the location the Doctor discovered the Time Lords had anticipated the treachery by rigging a bomb to the Temmosus, as it was boarded by Daleks, who had new orders from the Time Strategist to seize the vessel by force. The Doctor used his TARDIS to transport the ship back to Time Lord space where he negotiated with Tamasan to give the Thals more representation on the War Council. Afterwards he took the remorseful Dylon home to New Davius. (AUDIO: Temmosus)

The Doctor attempted to defend Lacuna from a raid of Berserker Daleks but arrived too late to stop the invasion so used his TARDIS to create a time loop of the last day before the planet was devastated. After hundreds of repeats as he tried in vain to find an outcome which would succeed, he was finally convinced to end the loop by Ignis Abel, though he promised to try and find a way to return and save them in the seconds remaining if he could. (AUDIO: Rewind)

Mission against the Barber-Surgeon
The Doctor became embroiled in the Barber-Surgeon's campaign, witnessing Peladon being "consumed" which proved to him just how dark the war could get. After he brought down a creation of the Barber-Surgeon which was attacking Gallifrey's defences, the Doctor was brought before the "inner circle" of the War Council by the General and was tasked with the assassination of the Barber-Surgeon. He accepted and was transported by a Time Lord supply ship to Kembel, the site of a recent attack.

Finding decimated Daleks, the Doctor located a survivor who told him of the Barber-Surgeon's attack and that the Daleks' knowledge of him could be found in the imperial datacore. Fleeing a Dalek Hunter-Killer, whose forces dispatched the other Time Lords accompanying him, (AUDIO: The Mission) the Doctor made for Skaro in his TARDIS, arriving in the midst of an attack by the Barber-Surgeon's creatures. Landing in Kaalann, he was swiftly captuded by Spider Daleks and taken before the Dalek Time Strategist. The Strategist chose to let the Doctor escape with his information, claiming he was the best chance of dealing with their mutual enemy, and he returned to his TARDIS. As he left Skaro the Doctor was intercepted by Time Lord commander Narthex who revealed he'd been sent by Leela to aid the Doctor and showed him a recorded message from Leela. Reluctantly accepting Narthex's help, the Doctor used the information from Time Lords and Daleks to deduce the entrance to the Barber-Surgeon's factory lay on Earth in 100000 BC.

The TARDIS was ambushed by an abomination as they arrived, resulting in the ship crash landing and perishing. Solemnly abandoning his vessel, the Doctor and Narthex searched the area and found the body of the War Master, killed by the Barber-Surgeon on a previous assassination mission. Shedding a tear for his old enemy, the Doctor worked out his corpse had been arranged as a clue, pointing to a cave where they found a portal to another dimension.

There he and Narthex were ambushed by the Hunter-Killer, who killed Narthex. The Doctor tricked the Hunter-Killer into triggering a defence of the portal, immobilising it, however upon reaching the portal Dalek reinforcements appeared. Surrounded, the Doctor furiously goaded them into exterminating him, (AUDIO: The Abyss) however awoke to find he'd only been taken captive instead. Escaping the Daleks after numerous interrogation sessions, he encountered the Constable and the Companion, deducing he was actually in the Barber-Surgeon's dimension. The Barber-Surgeon finally met him in person, revealing the Dalek captivity and encounters had served as a test of whether he was still the Doctor at heart, as the Barber-Surgeon was dying and knew he could not end the Time War himself anymore. Content the Doctor would do what it took to end the war, the Barber-Surgeon gave him a time ring to escape his dimension as he activated his unfinished doomsday weapon to erase himself and his factory from history. With the Barber-Surgeon's campaign undone, the Doctor was subsequently reunited with his restored TARDIS by the General. (AUDIO: The Horror)

Aged by war
When the Void began to attack and devour the universe, the War Doctor became trapped with his first seven incarnations after the escape of the Eighth Doctor. He was followed shortly by his ninth, tenth and twelfth incarnations, who ventured into the Type 1 TARDIS responsible for the disturbance. Forming a plan with the trapped Eleventh Doctor, the Doctors joined their TARDISes to pacify the Type 1 into a peaceful state and return the universe to normal. (COMIC: The Lost Dimension)

As the war continued, the Doctor slowly aged into an old man as he fought the Horde of Travesties, the Army of Meanwhiles and Neverweres, and the Skaro Degradations and their standard Dalek kin. (PROSE: A Prologue) At some point during the conflict, he once found a Dormouse that had survived a great battle, inviting it aboard the TARDIS. (PROSE: The Red and the Blue)

The War Doctor arrived late to the temporal meta-collision started by the Fourth Doctor to organise his other incarnations against a pandimensional entity that was trying to use the TARDIS to invade the Earth. The War Doctor realised that the cat photos his sixth incarnation was sharing were encoded location vectors pinpointing where the entity was going to invade first and materialised his TARDIS at all the planned arrival points to stop its invasion before it began, just as the Sixth Doctor installed a way to expel the entity from the Fourth Doctor's TARDIS. With the crisis over, the War Doctor went off to continue fighting in the Time War. (WC: Doctors Assemble!)

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-plunger 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 the Time Lords could, the War Doctor was sent to deal with the situation. (COMIC: Pull to Open) He formed a pact with, (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 Doctor and the Master soon encountered the Volatix Cabal, killing one of its members together. (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, instead using it to banish 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, creating a paradox that reacted with the Songbox, which in turn began to collapse timelines, resulting in a 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, his time with the Master, the Cyclors, 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. (COMIC: Physician, Heal Thyself)

The Keska incident
The Doctor dematerialised his TARDIS at Omega One as Bennus and Arverton were about to detonate the Time Destructor on the Dalek Fleet. Believing he had a higher chance of surviving the ordeal, the Doctor ordered the two Time Lords to return to Gallifrey and detonated the device himself. (AUDIO: The Innocent) Surviving through pure luck, (AUDIO: The Thousand Worlds) the Doctor crash-landed his TARDIS on the planet Keska, where he entered a healing coma that lasted for one hundred days, during which he was nursed to health by a native Keskan named Rejoice. Upon regaining consciousness, the Doctor helped the Keskans stop the Taalyens from wiping them out in their war, constructing a force field to protect Keska. Remaining on Keska for one-hundred-and-thirty-four days to recover from the effects of the Time Destructor and have some peace and quiet from the Time War, the Doctor struck up an unintentional friendship with Rejoice, who would visit him despite his insistence on being left alone.

When a Time Lord operative named Veklin arrived to collect the Doctor for Cardinal Ollistra, he dismissed the summons in favour of going boating with Rejoice, where he informed her of his feelings and history with the war. After a burst of anger from him caused Rejoice to abandon ship to swim to the shore, the Doctor and Rejoice were dragged back to Gallifrey in the TARDIS by the powers of the Eye of Harmony under Ollistra's command. After Rejoice was returned to Keska, (AUDIO: The Innocent) the Doctor was assigned the mission to locate Seratrix in the Null Zone with Veklin, Bennus and Arverton.

However, the Doctor summoned his TARDIS to him with his sonic screwdriver and decided to enter the Null Zone on his own. He landed on Keska again and discovered that the Daleks had helped the Taalyens bypass the force field. Meeting up with Rejoice again, though many years later from her perspective, the Doctor discovered that Seratrix had made an alliance with the Daleks to stop the Time War and ensure peace by allowing them dominion over the Null Zone, at the cost of the thousand worlds within it, which were to be destroyed in the Daleks' final assault on Gallifrey. (AUDIO: The Thousand Worlds)

The Doctor and Rejoice tried to convince Seratrix of the Daleks' deception, only to discover that Seratrix, Bennus and Arverton were part of a Time Lord conspiracy sect that was trying to form a peaceful truce with the Daleks. After Seratrix, Bennus and Arverton were killed by the Daleks after being convinced of the Daleks' treachery, the Doctor allied himself with the leading Taalyen to destroy the Daleks by deafening them and had his Keskan allies detonating the drill early to stop the Daleks' scheme. However, the Doctor was betrayed by Taalyens, and Rejoice was apparently killed. With their mission complete, the Doctor and Veklin were collected by Ollistra, who revealed the entire incident was her attempt to purge out Seratrix's conspiracy. (AUDIO: The Heart of the Battle)

The Neverwhen gambit
Travelling to Vildar to destroy the Annihilator, the Doctor was assisted by a reluctant soldier named Collis, but she was killed protecting him from a Varga plant. Knocked unconscious by the destruction of the Annihilator, the Doctor was deemed dead and taken to Aldriss, the planet of the Technomancers that had been reviving dead Time Lords, such as Collis. Discovering that the Valdarians were being sacrificed to revive the dead, and that a small part of the Technomancer's masters, the Horned Ones, were being placed in the revived Time Lords, the Doctor and Collis 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.

Escaping Aldriss with co-ordinator Jared, the Doctor was apprehended by Ollistra, who informed the Doctor that he was to be arrested as a war criminal. (AUDIO: Legion of the Lost) The Doctor was placed in an Artron leash, and tasked with discovering the purpose of the anima device on Asteroid Theta 12 with Ollistra, Jarad and Captain Solex. After losing Jared, they discovered that the Daleks were retro-engineering themselves back into Kaleds in order to gain a new insight into war. After Solex sacrificed himself to save him, the Doctor allowed Ollistra to use the anima device for their escape and then freed himself from the Artron leash to leave in his TARDIS. (AUDIO: A Thing of Guile) However, Ollistra had programmed the TARDIS to travel into the explosion of the anima device; the Neverwhen. There, the Doctor initially helped a set of soldiers against an aggressor, until the time phasing revealed he had been assisting retro-evolved Kaleds battle primitive Time Lords.

Once 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, the Doctor instead stopped it from working in the first place, attempting to use it to create a state of peace where both Daleks and Time Lords were farmers. However, the conflict was so ingrained that the residents of the new timeline still ended up fighting. When Ollistra insisted on resuming her initial plan, 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 on board 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)

Learning that Rassilon had made an alliance with the Nestene Consciousness, the Doctor convinced the Nestene to bargain with him instead of Rassilon. After agreeing to fight for the Nestene in the future, the Doctor learnt that Rassilon had asked for an Auton to be made with the Doctor's likeness in order to have his soldiers more susceptible to his manipulations, such as General Artarix. Given control of the Auton by the Nestene, as well as a second Auton to distract Rassilon, the Doctor stole a handful of proximity mines from the Panopticon, and used them to save Artarix's fleet from a Dalek ambush. With his Auton duplicates having self-destructed, the Doctor left it to Artarix to confront Rassilon. (PROSE: Decoy)

Opposing the Dalek Time Strategist
The Doctor was sent to Earth by Ollistra to stop the Dalek Agent Lara Zannis from operating the Shadow Vortex in 1961 Berlin, but they were both captured by the Stasi in East Berlin and interrogated by Kruger. After Zannis escaped, the Doctor convinced Kruger to release him, and they made their way to West Berlin to stop her, only to arrive too late. In order to stop the Dalek invasion, the Doctor materialised around Zannis and the Shadow Vortex, took them back in time by a few minutes, and landed on top of Zannis's past self, separating the two timelines and trapping Zannis in an alternate timeline.

Returning to the Time War, the Doctor was informed by Heleyna that Ollistra had been kidnapped. (AUDIO: The Shadow Vortex) He devised a plan to get onto Rovidia to rescue Ollistra from the Sontarans, who were also ransoming the Dalek Time Strategist to the Daleks. Using a stealth ship, the Doctor and Heleyna led a platoon of Time Lords with Muren arrived on Rovidia and, with the help of Kalan, they got to the citadel where the Sontarans were holding Ollistra. While experiencing a psychic pain, the Doctor came to realise that the Sontarans were aiming to become a third front in the war and that their hostages were bait for a trap.

Stopping the Sontarans from using the Eternity Cage with the aid of Vassarian, the dying Time Lord powering the cage, the Doctor managed to escape in Vassarian's Battle TARDIS with Ollistra, Kalan and Heleyna, only for Ollistra to expose Heleyna as a traitor. Heleyna tried to kill the Doctor by ejecting him from the TARDIS, (AUDIO: The Eternity Cage) but Ollistra used the TARDIS' transmat to bring him back on the ship after Heleyna was dealt with. However, Heleyna was able to escape into the ship with Ollistra, leaving the Doctor and Kalan to avoiding her traps as they searched for them.

The Doctor and Kalan eventually located them at the Eye of Harmony chamber, just as 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, stranding the TARDIS in the Vortex. With Kalan fatally wounded, the Doctor convinced Heleyna to detonate a Dalek Dark Matter bomb to give the TARDIS enough energy to materialise into real-time, at the cost of her life. (AUDIO: Eye of Harmony) Escaping the Time Vortex to a space station, (AUDIO: Pretty Lies) Kalan died from his injuries as the Daleks arrived after them. (AUDIO: Eye of Harmony) The Doctor and Ollistra were then captured and sent to the Daleks as a peace offering, but the Doctor managed to avoid capture by flying the capsule to Beltox.

Crashing on the planet, the Doctor and Ollistra were met by journalist Schandel, who wanted to interview the Doctor as a war hero, much to his irritation. After Schandel let slip that the Daleks were due to arrive on Beltox, the Doctor alerted the locals in the city of Fergil, and helped to defend them by augmenting their climate control system to become a shield. When Schandel offered his assistance, the Doctor realised he could trick the Daleks into thinking that he had tremendous firepower by editing a message to them, securing his victory. After Schandel was killed by a Dalek straggler, the Doctor and Ollistra took Schandel's time ship to its next destination in the hopes they could contact Gallifrey. (AUDIO: Pretty Lies)

Learning of someone called the "Lady of Obsidian" from Schandel's files, the Doctor asked Rosata Laxter to help him locate her while Ollistra remained on Grend to contact the Time Lords. Arriving at the Obsidian Nebula, the Doctor discovered that the Lady was really Leela, who had been struck by a Disruptor Dalek early in the War and displaced from time and space until she reformed with her memories altered to include all of her possible timelines. The Doctor was able to convince Leela of their shared history and friendship and helped her close a breach that caused the Unlived to get into the universe, though at the cost of Rosata's life.

With Ollistra having contacted the Time Lords, the Doctor was reunited with his TARDIS, and took Ollistra and Leela back to Gallifrey. (AUDIO: The Lady of Obsidian) When Leela began feeling a sadness and seeing Dalek shadows on Gallifrey, the Doctor and Ollistra found a force from another universe called the Enigma was communicating with them through Leela, before it erased the Time Lords from history on the orders of the Dalek Time Strategist.

Escaping the onslaught in his TARDIS, the Doctor, Ollistra and Leela ventured into the Enigma's dimension, where the Doctor learned that the Enigma was being forced to the Daleks bidding and was using emotions to communicate with Leela, and had given the Doctor a warning due to Leela's trust in him. While Ollistra wanted to use the Enigma to restore the Time Lords and wipe out the Daleks, the Doctor instead chose to ask it to bring an end to both races to truly end the Time War. However, the Enigma chose to do neither, restoring the Time Lords after the Daleks and the TARDIS were ejected from its dimension. (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 the War Master, who had fled from the War, but the Doctor couldn't find any trace of his old enemy. (PROSE: Engines of War)

The Doctor enlisted the help of Dorium Maldovar to help him destroy the thirteen weapons factories of Villengard before the Dalek Fleet arrived to take control of them. Using a molecular fruit bomb, the Doctor transformed the factories into palm trees, creating a banana grove. (COMIC: The Whole Thing's Bananas)

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 so they could win the Time War. 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, (PROSE: Engines of War) in preparation for their exile from Gallifrey. (PROSE: The Whoniverse)

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, 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 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 plan to rupture the Time Vortex and destroy the universe and took it upon himself to end the war. (TV: The End of Time) After using a stolen gunship to burn "NO MORE" into the Dalek City on Skaro, destroying most of the Dalek Emperor's fleet in the process, (PROSE: 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. (TV: The Day of the Doctor) During the battle, he was sighted by a Dalek drone. Consumed by fear it fired aimlessly at him, missing entirely. (PROSE: Dalek) He used a soldier's gun to inscribe the words "NO MORE" onto a wall as a message to the Time Lords, with his presence baiting several nearby Daleks away from innocent Gallifreyan refugees they’d cornered. He then destroyed the group of Daleks with his TARDIS as he left. With the Time Lords distracted by his message, the Doctor 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 then disappeared into the Drylands of Gallifrey, (TV: Hell Bent) far from Time Lord observation, (TV: The End of Time) 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 his tenth and eleventh incarnations 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 could awaken when Earth became a more advanced place to invade. After the Tenth Doctor married the Queen, the War Doctor joined his future incarnations in travelling to stop the Zygons in 2013, with Clara revealing they had infiltrated UNIT and taken over the Black Archive.

With the Black Archive impenetrable from the TARDIS, the War Doctor deduced a way in, which involved the Eleventh Doctor ordering UNIT scientist 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, Petronella 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 group they belonged to.

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 incarnations joined him to press the button, finally forgiving him and themselves for destroying Gallifrey, 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 Eleventh 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. Working together, the thirteen Doctors managed to move Gallifrey and the Daleks were destroyed in the crossfire.

Meeting up at the National Gallery, the War Doctor voiced his uncertainty of their success to his tenth and eleventh incarnations, but took solace in the fact they may have "failed at the doing the right thing, as opposed to succeeding in doing the wrong". While he was pleased that he could call himself "the Doctor" once again, he also reminded himself that he would forget his attempt to save Gallifrey due to the timelines being out of sync, and bade farewell to Clara and his future selves and left in his TARDIS, (TV: The Day of the Doctor) feeling the regeneration he had been fighting off for "years" was about to begin. (PROSE: The Day of the Doctor)

Death
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 the timelines were "out of sync" so 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 as a war hero. (TV: Hell Bent)

Post-mortem
According to one account, the Ninth Doctor could not remember the time between the end of his eighth incarnation, who he associated with the "happy jumbled days" before the Time War, and the beginning of his own life. (PROSE: The Eighth Doctor Part 2) By most other accounts, however, the Doctor vividly remembered the Time War. While the Doctor made no secret of his part or actions in the 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 the war 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)

John Smith's A Journal of Impossible Things featured a partial drawing of the War Doctor, "as if his face had been burnt from the page". The text alongside stated that the two following pages "ha[d] been glued together", "not through accident". (PROSE: Extract from "A Journal of Impossible Things")

During the Planetary Relocation Incident, the Tenth Doctor learned that Davros had in fact not died at the Gates of Elysium. Instead, after entering the Time War, Dalek Caan had done what the War Doctor had failed to do, as he managed to save the Dalek creator from certain death. (TV: The Stolen Earth) When the Tenth Doctor later met the Time Sentinels on Dark Ages Gallifrey, he was dismayed to find that they knew of the War Doctor as a war hero. (COMIC: Old Girl) During many failed attempts to duplicate the Tenth Doctor, defective copies of all his past incarnations, including the War Doctor, were created instead. (COMIC: Breakfast at Tyranny's)

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)

The Eleventh Doctor briefly turned back into his war incarnation when his TARDIS was caught in a time loop caused by Alice escaping the Time War inside the Then and the Now. (COMIC: Fast Asleep)

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". The War Doctor reminded his future self that the action he took was in the name of peace and sanity; though not in the name of "the Doctor". 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. When 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)

In a guide for her next incarnation, the Thirteenth Doctor admitted that she did not "remember much" of the War Doctor's experiences, but hoped that her successor would, stating that the War Doctor deserved to be remembered. (PROSE: A Short History of Everyone)

Alternate timelines
In one of several alternate timelines shown to the Tenth, Eleventh and Twelfth Doctors by a continuity bomb, the War Doctor was converted into a Dalek Slave. (COMIC: Four Doctors)

In an alternate timeline where Rassilon gave the Cybermen the means to conquer all of time and space, (COMIC: Supremacy of the Cybermen) the War Doctor fought in an alternative version of the Last Great Time War, with the Cybermen replacing the Daleks (COMIC: Prologue: the War Doctor) after the Cybermen erased the Daleks from existence. (COMIC: Supremacy of the Cybermen) In this timeline, the War Doctor detonated the Moment inside the barn as it was surrounded by Cybermen. (COMIC: Prologue: the War Doctor) Ultimately, this timeline was erased by the Twelfth Doctor and a betrayed Rassilon, when, on Gallifrey at the end of the universe, they used the regenerative energy stored in the Eye of Harmony to regenerate the universe via the Cyberiad's dominance across all of history. However, the Twelfth Doctor retained full memories of his actions in this timeline. (COMIC: Supremacy of the Cybermen)

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 with the "philosophies and ideals" shared with it (PROSE: The Day 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) as he did not carry a name "as a rule". (AUDIO: The Eternity Cage) He would show great irritation, and even extreme bouts of anger, with anyone who addressed him as "Doctor", especially if they did so after he committed what he considered to be an atrocity. (AUDIO: The Innocent, The Thousand Worlds, The Neverwhen, Eye of Harmony, The Enigma Dimension; COMIC: Kill God, Physician, Heal Thyself, The Clockwise War; PROSE: The Third Wise Man)

Rather than a "good man", the War Doctor saw himself as a "lost cause" that did what was necessary to end a "sorry chapter of cosmic history", as it was his "reason for being." (AUDIO: The Innocent) His inability to find an alternative to end the Time War consumed him with so much guilt he considered it easier to view himself as a different man to the Doctor. (AUDIO: The Neverwhen) He even made himself believe that he had killed "the Doctor" on Karn. (PROSE: The Day of the Doctor) He did not see himself as a "hero", (AUDIO: Pretty Lies) instead thinking himself as a "monster" that was "steeped in the blood of war", (AUDIO: The Innocent) becoming "the stuff of nightmares" and "a demon let loose on the time streams". (AUDIO: Pretty Lies) However, he would immediately turn apologetic when he realised that he had stepped out of place, (AUDIO: The Innocent) and considered himself on the side of the collateral in the war, with the idea of having to sacrifice innocents weighing heavily on him, (AUDIO: Legion of the Lost) and also believed that he fought for the sake of the other Time Lord soldiers, particularly the ones that looked to him for inspiration. (PROSE: Decoy)

During his first years fighting in the Time War, the Doctor saw the conflict as "a challenge to overcome", and showcased an arrogant and egotistical persona, not unlike his sixth incarnation. He made puns in the face of the Morlontoa, and viewed himself as "handsome", "brilliant", and "modest", though Fey Truscott-Sade instead described him as "irritating". Following the loss of Fey, the Doctor came to see the war as a "tragedy to face". (COMIC: The Clockwise War) Due to the intensity of his life brought on by the Time War, the Doctor would show genuine surprise when arriving somewhere that hadn't been touched by the fighting. (AUDIO: The Innocent)

As he grew older, the Doctor wanted the war to end, but felt it was his duty to continue to fight and play his part. (AUDIO: The Innocent) Despite wanting to see the hostilities end, he did not believe peace with the Daleks would ever be possible. (AUDIO: The Heart of the Battle) He instead took peace in the certainty of death being the one dependable constant. (AUDIO: Legion of the Lost) For a while, he wished for his own death, so that he would no longer have to face such choices. (AUDIO: The Innocent, The Heart of the Battle)

The War Doctor could be cagey and cranky, but would return the kind treatment he received from those who did not antagonise him if he was in a good enough mood. (TV: The Day of the Doctor; AUDIO: The Innocent, The Eternity Cage) He was overjoyed to be reunited with Leela, (AUDIO: The Lady of Obsidian) and the two quickly regained their old rhythm of teamwork. (AUDIO: The Enigma Dimension) He also made a point to be nice to fellow soldiers, and inspire them to continue. (AUDIO: The Neverwhen) While he did not accept acts of gratitude for his actions, he would ask for peace and quiet as a reward when the opportunity presented itself. (AUDIO: The Innocent)

He acknowledged that the Time War had changed him, (PROSE: The Stranger; AUDIO: A Thing of Guile) making him renounce offering chances to his enemies, (COMIC: Kill God) and unable to make the same promises his previous incarnations could, (COMIC: Four Doctors) recognising that his previous selves would hate what he had become, (AUDIO: The Neverwhen) and also reflected how he was a lesser man than his successors, having become great men from the guilt they suffered from his actions. On meeting his future selves, the War Doctor viewed it as his privilege to "light the flame" that would forge their greatness. (TV: The Day of the Doctor)

He would also state the facts without thought for niceties or the fear he was spreading through these facts. (PROSE: Engines of War; AUDIO: The Innocent, The Eternity Cage, Pretty Lies) 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". 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 was tired of the suffering and anarchy the Time War had caused, having lost the will to survive beyond the war and his self-beliefs, but still maintained a whimsical charm, (TV: The Day of the Doctor) being very attached to his TARDIS and overjoyed when reunited with it after an extended period of time. (AUDIO: The Lady of Obsidian) He also addressed the TARDIS as "old girl", did not wish to get his boots dirty in case he made a mess when he stepped in the TARDIS, (PROSE: Engines of War) and reassured Siatak that he would act as an intermediary between the Time Lords and the Voord when the war ended. (COMIC: Four Doctors)

Though the Time War caused the War Doctor to be saddled with much regret, sadness and weighted guilt, he also managed to be cheerful and compassionate with a few moments of witty humour and sarcasm, such as throwing Veklin's rude comments back at her with a laugh, (AUDIO: The Innocent) refusing to identify himself after his interrogator demanded his silence, (AUDIO: The Thousand Worlds) wryly replying that he felt "terrific" when questioned by Jarad, (AUDIO: Legion of the Lost) mocking Kruger's attempt to intimidate him during an interrogation, (AUDIO: The Shadow Vortex) laughing at jokes he accidentally made, (PROSE: The Stranger) telling Cinder they had "places to go, [and] people to see" while joyfully sneaking into Andor, joking that the Eternity Circle of Daleks weren't a circle while drawing an imaginary circle in the air with his finger to demonstrate his point, (PROSE: Engines of War) quipping that it was Lord Bentham's "lucky day" for unknowingly stumbling upon three incarnations of the Doctor at once when Bentham threatened the Doctor for apparently bewitching the Queen, (TV: The Day of the Doctor) and pretending not to know which TARDIS was his as a joke for his successors. (PROSE: The Day of the Doctor)

Being open-minded, (AUDIO: Legion of the Lost) the Doctor believed in keeping his word, (AUDIO: The Heart of the Battle) and second chances. (PROSE: Engines of War) While he stood by the right for others to possess free will, (AUDIO: A Thing of Guile) he was willing to strip it away if it meant peace. (AUDIO: The Neverwhen) He also thought that those "who would seek the Godhead must first walk with angels", (COMIC: The Organ Grinder) and that, as "great minds [thought] alike", "fools seldom differ[ed]" on strategies. (COMIC: The Lost Dimension)

He enjoyed the fruit juice of Keska, (AUDIO: The Innocent) a good cup of tea, (AUDIO: Legion of the Lost) bananas, (COMIC: The Whole Thing's Bananas) cats, (WC: Doctors Assemble!) and also considered books, marshmallows and Earl Grey tea specifically 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 found the Tantalus Eye to be breathtakingly beautiful, (PROSE: Engines of War) had fond memories of Marinus as a "lush world of many ecosystems", (COMIC: Four Doctors) and also maintained his old fondness for Earth, (AUDIO: The Innocent) and had good memories of Vildar. He held a great respect for artists and intellectuals, calling the Vildarans "beautiful". (AUDIO: Legion of the Lost)

The Doctor voiced a continual dislike for working for the Time Lords, claiming he preferred to fight the war on his own terms, (AUDIO: The Innocent, The Thousand Worlds, A Thing of Guile, The Neverwhen) and believed that their dedication to order and discipline made them no different than the Daleks, (AUDIO: The Thousand Worlds) especially when they tried to justify the killing of "lesser beings" in the crossfires of the war. (PROSE: Engines of War; AUDIO: The Heart of the Battle) He was particularly "disgusted" to be on "the same side" as Ollistra (AUDIO: The Heart of the Battle) and. (PROSE: Engines of War)

The Doctor would get particularly short-tempered with those he thought were taking too long to think, (PROSE: The Third Wise Man) and also disliked not having the last word in a negotiation. (AUDIO: Eye of Harmony) He also would not stand for being patronised, (AUDIO: Legion of the Lost) and strongly believed that the dead should stay dead, and was horrified to find that the Time Lords had been reviving soldiers to serve as "cannon fodder". (AUDIO: Legion of the Lost)

Similar to his seventh incarnation, the War Doctor was 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 as being done "without choice" and "in the name of peace and sanity." (TV: The Name of the Doctor)

Convincing himself to believe he was a different man with different ideals to his predecessors, (AUDIO: A Thing of Guile) the War Doctor was prone to bouts of anger and rage, especially when democracy prevented him from taking action to save lives. (AUDIO: Pretty Lies) He roared in grief for Cinder and the Fifth Time Lord Battle Fleet, and hoisted Karlax by the throat in the air when provoked. (PROSE: Engines of War) He sometimes heard a voice in his head that represented "the Doctor" trying to convince him away from violence, but he forced himself to shut the voice behind a door in his mind. (PROSE: The Day of the Doctor)

Unlike his other incarnations, the War Doctor endorsed the use of weapons, holding Dorium Maldovar at gunpoint to coerce his cooperation, (COMIC: The Whole Thing's Bananas) 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) He even commented that a gun fitted his hand better than psychic paper did. (COMIC: The Organ Grinder) However, he was known to enter battles unarmed in the Time War, (TV: Hell Bent) expressed dismay at using "doomsday weapons", (COMIC: The Organ Grinder) 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)

The Tenth Doctor admitted that he had "killed" others during the Time War. (TV: The Doctor's Daughter) Indeed, the War Doctor could react mercilessly to a situation; showing delight at the sight of Daleks being killed by a chronic tripwire, (COMIC: Four Doctors) killing Lara Zannis by un-writing her existence, (AUDIO: The Shadow Vortex) 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) While he still felt grief for the pain he inflicted and guilt for the lives he had to take, the Doctor did not allow his feelings to deter him from his objective to end the war, (PROSE: The Day of the Doctor) and felt despair when he found out the consequences of his hard decisions were undone. (AUDIO: Legion of the Lost, The Enigma Dimension)

However, he believed that mercy was a strength, and valued life above all else. (PROSE: Engines of War) He vehemently opposed the murder of any sentient being, (AUDIO: Legion of the Lost) apart from the Daleks, (AUDIO: The Heart of the Battle) arguing at length with 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) He also hesitated to destroy Gallifrey when forced to think of the innocent children he would kill as a result. (TV: The Day of the Doctor) He refused to kill Project K006 out of pity, (AUDIO: A Thing of Guile) and was unwilling to follow a plan that would have resulted in the Daleks wiping out the Sontarans. (AUDIO: The Eternity Cage)

Despite focusing on the grand scale, the Doctor still had his limits, and would try to employ less "extreme" and more "harmless" measures whenever he could, aiming to allow himself to be the sole casualty of his plans, (AUDIO: A Thing of Guile; COMIC: The Organ Grinder, The Whole Thing's Bananas) and constantly tried to have the Time Lords avoid using dubious and lunatic tactics to win the War. (AUDIO: The Heart of the Battle, Legion of the Lost; COMIC: The Bidding War) He was appalled by the depths Rassilon and the High Council had sunk to in the Time War, and was both outraged and disgusted when he found out Rassilon had retro-evolved Borusa into a possibility engine. (PROSE: Engines of War)

As he continued to try and minimise the damage caused by the crossfires of the Time War, the Doctor would work to save as many lives as he could, (AUDIO: A Thing of Guile, The Neverwhen, The Eternity Cage; COMIC: Kill God) while ensuring that no one sacrificed their lives in vain. (AUDIO: The Innocent, The Heart of the Battle, Legion of the Lost; PROSE: Decoy)

Due to the horrors he had seen, the Doctor would often speak in a monotone voice when dealing with individuals he had no interest in, (PROSE: The Third Wise Man) even forgetting people with "forgettable face[s]" when they were stood in front of him. He was accustomed to people looking upon him with terror, (PROSE: The Day of the Doctor) and accepted that the Daleks' schemes for victory would become more hideous and overblown with each attempt. (AUDIO: The Thousand Worlds)

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 on board 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)

Despite being more concerned with the Time War than defending 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 his tenth and eleventh incarnations 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. 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. (TV: The Day of the Doctor)

While he enjoyed watching them "[work] together to solve a problem", (WC: Doctors Assemble!) the War Doctor did not reflect fondly on his predecessors, believing them to be "posturing, prancing fool[s]" who "lived for the thrill of stepping through a door and seeing all [the] faces turn towards [them] in hope and wonder". (PROSE: The Day of the Doctor) He especially demonised his fourth incarnation for not having "the guts to do what was necessary" when his hesitation to destroy them ensured the creation of the Daleks, (PROSE: Engines of War) but praised his sixth incarnation for his cleverness. (WC: Doctors Assemble!)

Seeing him as "foolish", (AUDIO: Light the Flame) the War Doctor had a low opinion of his eighth incarnation, viewing him as a "romantic idiot", (COMIC: The Lost Dimension) who had the arrogance to "[mistake] himself for a hero" and make jokes at often inappropriate times, (PROSE: The Day of the Doctor) though he did admire him for being a "romantic hero with hope." (AUDIO: Light the Flame)

The War Doctor was critical at first of his tenth and eleventh incarnations, finding them to be very childish and ashamed to be grownups, and branding them a "midlife crisis". (TV: The Day of the Doctor) As a consequence of their youthful appearance, the War Doctor had at first believed them to be children playing dress up, and their sonic screwdrivers to be magic wands. He also had difficulty telling the two apart. (PROSE: The Day of the Doctor) He was particularly critical of the Eleventh Doctor, disliking his use of the phrase "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. (TV: The Day of the Doctor) He was particularly annoyed by the apparent lack of dignity and wisdom they showed, likening them both to presenters of Blue Peter. (PROSE: The Day of the Doctor) However, after watching them use their guilt from the Time War to 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 Eleventh Doctor tried to remember his war incarnation as "the slaughterer of billions", when standing before him, he reflected that the War Doctor was "kind, and brave, and hurt", and had never been "a warrior in his hearts". (PROSE: The Day of the Doctor)

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, instead taking comfort in the sound of the TARDIS control console. (PROSE: Engines of War) He claimed to Rejoice that he also chose not take on companions due to his dislike of them asking questions. (AUDIO: The Innocent)

Despite having a rocky start to their relationship, the Doctor grew to genuinely care for Cinder and tried to force her away from him, worried that he wouldn't be able to protect her from the Time War. When she did indeed meet her demise while protecting him, the Doctor became tempted to use a possibility engine to undo her death, but instead decided to honour her sacrifice by using the engine to destroy the Daleks. He later hunted down her home to give her a proper burial with her family. Cinder's death proved to be the last straw for the Doctor, who swore he would end the Time War in her memory. (PROSE: Engines of War)

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 also slaughter children with Gallifrey. (TV: The Day of the Doctor)

He was afraid of the powers and capabilities of the Daleks, and the possibility that the Time War would continue after the defeat of the Daleks, with the Time Lords becoming warlike enough to find a different enemy to fight in the Daleks' place. (AUDIO: The Enigma Dimension) He also believed the Daleks to be even more arrogant than the Time Lords. (PROSE: Engines of War)

While the Eleventh General considered him a "mad fool", Clara Oswald, when distinguishing him from the Doctor's other incarnations, described the War Doctor as "the warrior". (TV: The Day of the Doctor) The Squire recalled how the War Doctor carried "pathos" with him, (COMIC: The Then and the Now) but noted that he was still a "noble warrior". (COMIC: Outrun) Ollistra, however, believed that, instead of being a "man of war", the War Doctor sometimes allowed himself to think of himself as a "compassionate man with high moral standards", (AUDIO: The Heart of the Battle) though commentated how the War Doctor's "morals [were] entreatingly fluid". (COMIC: The One) Co-ordinator Jarad considered the Doctor a "wily old fox" who could out-think everyone. (AUDIO: Legion of the Lost)

Rojan, after seeing the War Doctor's elderly face, felt that he "wasn't a man who found much joy in life." (PROSE: The Stranger) Artarix, when gazing at the Doctor's Auton duplicate, felt that he "bore the weight of regret" of being "a man who had been forced to become the very thing he despised". (PROSE:Decoy)

Due to the severity of the war, the Doctor was convinced there was no future beyond the conflict, (TV: The Day of the Doctor; COMIC: The Organ Grinder) and did not mind if he died whilst fighting in the Time War, (COMIC: Kill God) having resigned himself to death "the moment [he] entered [the] war", (AUDIO: Legion of the Lost) and would put himself in situations that he had a low chance of surviving in, (AUDIO: The Innocent) with the mind-set that he would "[go] out fighting". (PROSE: Engines of War) However, he stated he had a reluctance to die at Collis's hand, (AUDIO: Legion of the Lost) and that he did not wish to become a martyr. (AUDIO: Eye of Harmony) He claimed that the only thing that was worth living for was the thought of the lives he had saved. (AUDIO: Pretty Lies)

Upon noticing his regeneration beginning, the Doctor showed no fear of the change, (TV: The Day of the Doctor) despite once describing regeneration as a "trauma", (AUDIO: Legion of the Lost) due to having held back the process for "years". (PROSE: The Day of the Doctor) Instead, he noted 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. However, due to the timelines not being synchronised, the Doctor believed he had destroyed Gallifrey, committing genocide against the Time Lords and the Daleks. (TV: The Day of the Doctor) 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's Man Hand) until the true outcome of the the Time War was revealed to the Eleventh Doctor, allowing the memory of the War Doctor to stand proudly with his other incarnations. (TV: The Day of the Doctor)

Habits and quirks
The War Doctor made a habit of incorporating "no more" into his dialogue and thought process, (TV: The Night of the Doctor, The Day of the Doctor; PROSE: Engines of War, The Day of the Doctor; AUDIO: The Eternity Cage; COMIC: Ambush) and justifying his actions as being done in "the name of peace and sanity." (TV: The Name of the Doctor; COMIC: First Rule, Kill God, Fast Asleep) He also made a habit of uttering "damn", usually as a sign of frustration or when things did not meet his satisfaction. (PROSE: Engines of War; AUDIO: The Innocent, The Thousand Worlds, The Heart of the Battle, A Thing of Guile, The Neverwhen, Eye of Harmony, Pretty Lies, The Enigma Dimension)

Much to the confusion of his fellow Time Lords, the Doctor was prone to making reference to Earth idioms and phrases. (PROSE: Engines of War; AUDIO: The Innocent, The Thousand Worlds, A Thing of Guile, The Neverwhen, Pretty Lies, The Enigma Dimension)

The War Doctor would often stand with his arms folded behind his back. (TV: The Day of the Doctor; PROSE: Engines of War; COMIC: The Organ Grinder) When standing between two people engaging in conversation, such as his tenth and eleventh incarnations, the War Doctor would turn his head to face the one that was speaking, even if it meant turning his head back-and-forth continuously. (TV: The Day of the Doctor)

Skills
The War Doctor had a strong knowledge of warfare tactics, (AUDIO: The Innocent, The Neverwhen, The Eternity Cage, Pretty Lies) and could deduce a person's history from sheer observation. (AUDIO: The Shadow Vortex) He could also deduce the height and weight of people and locations on sight, (PROSE: The Day of the Doctor ) and had a keen grasp on his surroundings, enough to know when he was being observed from behind. (AUDIO: The Innocent; PROSE: The Day of the Doctor)

The Doctor had a knack for gaining authority over others, being able to gain entry into secure locations by acting as if he was in charge, (AUDIO: The Shadow Vortex) and securing his entrance into Time Vault Zero by barking orders about a break-in at the guard until she was convinced to let him in. (PROSE: The Day of the Doctor) Even so, he favoured direct action over feigning authority. (AUDIO: Legion of the Lost)

Though not as quicksilver as his more able-bodied successors, the War Doctor paced his thinking, sometimes seeing a hidden solution after some contemplation. (TV: The Day of the Doctor) Though he told Cinder he "was not good with long-term plans", and preferred "winging it", (PROSE: Engines of War) the Doctor was able to think of effective stratagems in preparation for battle, (AUDIO: The Eternity Cage) with the Squire remembering him as "always [having] a plan". (COMIC: The One) Indeed, the Doctor had the foresight on one occasion 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)

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 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)

The 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 to wield a Temporal Cannon against a Dalek. (PROSE: Engines of War) He was even able to quickly review the effectiveness of a firearm after close examination. (AUDIO: Pretty Lies) 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)

He was skilled at hacking into the Daleks' databanks, (PROSE: Engines of War) as well as the Technomancer equivalent of a computer. (AUDIO: Legion of the Lost)

He was also able to determine the way casualties on a battlefield were killed by studying their corpses. (COMIC: The Organ Grinder)

He could detect nitrogen in the air by scent. (AUDIO: A Thing of Guile)

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. (PROSE: Engines of War)

The War Doctor could understand Dalek writing "to a degree". (PROSE: Engines of War)

The War Doctor could judge a person's character quickly, almost instinctively knowing who he could ally himself with, (AUDIO: The Shadow Vortex; PROSE: The Day of the Doctor) and recognising when someone wasn't a murderer (PROSE: Engines of War) or was acting out of fear instead of malice. (AUDIO: The Shadow Vortex)

He could assess 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) knowing the equipment others had on them by observing their use of technology, (AUDIO: The Innocent) ruling out the Moment's interface as a hologram by observing their surroundings, and determining the year as the 1560s by studying his location. (PROSE: The Day of the Doctor)

The War Doctor was capable of resisting a regeneration from old age for several years through willpower alone. (PROSE: The Day of the Doctor)

Appearance
At the start of his life, the War Doctor had a stern and determined face, green-brown eyes and messy brown hair following regeneration. Though he started off clean shaven, (TV: The Night of the Doctor) he let his stubble grow (COMIC: Ambush) until he grew a full brown Van Dyke beard. (COMIC: The Lost Dimension)

Ultimately, after spending "a very long time" fighting in the Time War, (TV: The Day of the Doctor) he became jaded and tired, his beard and hair having turned a haunting silver-grey, and with pronounced wrinkles on his craggy, careworn face, (TV: The Name of the Doctor) making him resemble a man in his seventies. (PROSE: Engines of War) However, Clara Oswald noticed his eyes were younger than those of his future selves, in that they were more hopeful. (TV: The Day of the Doctor) He slicked up his hair in peaks at the top of his head, (TV: The Name of the Doctor) and his deep, distinctive voice became well-known amongst the people aware of the Time War, (AUDIO: Pretty Lies) with the Tenth Doctor noting how it was "posh, [and] gravelly". (TV: The Day of the Doctor)

The War Doctor thought his ears to be "conspicuous", voicing to himself his hope that those of his next incarnation would be less so as his regeneration approached. (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) and Clara observed that he "seemed to carry the smoke of battle with him". (PROSE: The Day of the Doctor)

In his "twilight years", the War Doctor was observed by the Tenth Doctor as looking "small and frail, and afraid", as opposed to "someone to inspire dread", with the Eleventh Doctor seeing him as "broken, and humble." (PROSE: The Day of the Doctor) The War Doctor's aged appearance led his eleventh incarnation to jokingly codename him "Granddad." (TV: The Day of the Doctor)

Main attire
The War Doctor wore a leather trenchcoat done in either brown (TV: The Name of the Doctor) or black, (COMIC: The Whole Thing's Bananas) and a double breasted moleskin waistcoat in either ginger, (COMIC: The Clockwise War) mustard yellow, (COMIC: Fast Asleep) mahogany, (COMIC: The Whole Thing's Bananas) or dark green-brown moleskin, (TV: The Name of the Doctor) with 10 brass buttons and a fob chain attached to it. He also wore dark tan corduroy trousers, a box-frame belt with several fastener pins and studded pinholes, and dark brown boots adorned with charcoal leather gaiters, which had a few buttons missing. (TV: The Day of the Doctor)

For neckwear, the Doctor wore a scarf with either a beige design, (COMIC: The Clockwise War) a crimson colouring, (COMIC: Ambush) shaded in eggplant purple, (COMIC: The Lost Dimension) long and white, (COMIC: The Whole Thing's Bananas) made in maroon, (COMIC: First Rule) or knitted in a burgundy and ivory herringbone pattern. (TV: The Name of the Doctor)

His oldest article of dress was a bandolier across his left shoulder, taken from the body of Cass Fermazzi immediately after he came into being. (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)

Other clothes
During a rescue mission to Rovidia, the Doctor adopted a robed appearance to blend in with the Rovidians, justifying the simplicity of the disguise due to the Rovidians being "simple people". (AUDIO: The Eternity Cage)

Information from invalid sources

 * The War Doctor was described as having "the look of a battle-hardened warrior" by Strax in Strax Field Report: The Doctor's Greatest Secret, which is not accepted as a valid source for in-universe articles on this wiki.

John Hurt's age

 * John Hurt, aged 73 when he first appeared on-screen in The Name of the Doctor, is the oldest actor to portray the Doctor upon their debut appearance. The second oldest are William Hartnell and Peter Capaldi, who were both 55-years-old when they made their debut appearances, with Capaldi being several months older than Hartnell. Additionally, Richard Hurndall and David Bradley were 73 and 75, respectively, when they played the First Doctor on television. Unlike Hurt, however, they were playing an incarnation whose portrayal had already been established by another actor, namely Hartnell.
 * Though John Hurt was 73 when he debuted as the War Doctor, special effects were used to blend archive material of Hurt from earlier in his life to depict the War Doctor in a reflection 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 a 39-year-old John Hurt played Rodion Raskolnikov. (REF: DWMSE 38) The BBC itself later revealed which shot it was.
 * According to Emma Campbell-Jones, Paul McGann played the newly regenerated War Doctor in the scene where he takes Cass's bandolier after the regeneration. This makes McGann the second actor to 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 bears the 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. This does not include Richard Hurndall, who passed away just four months after stepping into the role of the already-existing First Doctor in The Five Doctors.

Place in the line-up

 * The War Doctor's existence and numberless designation was a workaround to Christopher Eccleston's having declined to participate in The Day of the Doctor. 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". 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 in The Time of the Doctor.
 * Excluding the pre-existing "Morbius" and "Merlin" Doctors, the War Doctor was the first incarnation of the Doctor to be introduced retroactively, initially existing to serve as a supporting character.
 * 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 in The Night of the Doctor and his regeneration into the Ninth Doctor in The Day of the Doctor were broadcast just nine days apart.
 * In the short story Doctor Who and the Time War, written by Russell T Davies, originally scheduled for release in 2013 but ultimately released in 2020 as a prequel to television story Rose as part of the Doctor Who: Lockdown! watch-along series due to worldwide outbreak of COVID-19, completely ignored the existence of the War Doctor due to Davies having had no knowledge of neither the war incarnation, nor the television story The Night of the Doctor, at the time it was written. As such, the Eighth Doctor regenerated directly into the Ninth Doctor in that story, with Davies offering the explanation on Instagram that the story is a "glimpse of parallel events" and stating on the author's commentary of the story's original upload on the BBC website that "all stories are true".

Doctor Who: Legacy
In the story of Doctor Who: Legacy, the War Doctor joins his other selves and their companions as they travel through time to stop and fix the damage caused by the Sontarans' attacks throughout history.

Other matters

 * 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", while the subtitles on The Day of the Doctor refer to him as the "Old Doctor". In a complete Doctor Who 50th Anniversary Special draft, the War Doctor calls himself "the Renegade."
 * 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.
 * The War Doctor was the first of the incarnations of the Doctor introduced in the BBC Wales-produced series of Doctor Who to appear in Big Finish Productions.
 * The War Doctor is the only confirmed incarnation of the Doctor not to be one of the Dr. Men.
