Sixth Doctor

Bumptious, melodramatic, and above all stubborn, the Sixth Doctor instantly believed himself superior to almost anyone he encountered. He would often browbeat others into submission with his savage wit and his grammarian's interest in language. Even so, his mercurial and flippant tendencies did not define the true heart of his persona. Beneath his thunderous and turbulent exterior, he was quite the opposite: a passionate, warm, virtuous and empathetic individual.

He was profoundly difficult with his first companion, Peri Brown, whom he initially challenged for her use of American English and her as-yet-incomplete education. Indeed, during the early hours after his regeneration he physically assaulted her due to post-regenerative paranoia. It took considerable time for himself and Peri to stop bickering and speak together on amiable terms, but the Sixth Doctor eventually became someone she could rely upon. With enough distance from the regenerative event, she was able to look to the Doctor for strength after her mother's death.

Despite his bluster, the Sixth Doctor did possess great reserves of compassion. His gentler side began to blossom largely as a consequence of travelling with Evelyn Smythe, a university lecturer whose verbal dexterity was on a par with his own. Also helpful to this transition were Frobisher, a shapeshifting private eye who often masqueraded as a penguin, Flip Jackson, a young woman from twenty-first century London, and Melanie Bush, a brilliant computer programmer from Earth in the 1980s.

A dominant feature of his life was yet another Time Lord trial. Though this one sought to blame him for a shifting docket of crimes, it in fact turned out to be an elaborate ruse. He later found himself in a reverse situation where he became the prosecutor against the Valeyard, the malicious being that had framed him in an attempt to steal his regenerations. He discovered that the Valeyard's dubious existence was somehow tied to his own and took shape from his inherently darker characteristics.

Long after this trial, the Doctor was slowly manipulated by the Valeyard across different moments of his life until the Valeyard had the means to replace all Time Lords in existence. Forced to arrange his own demise to prevent this genocidal plot, the Sixth Doctor was influenced by his next incarnation into inadvertently crossing paths with, who dealt him a fatal blow. He regenerated, putting his future in the hands of his successor.

A day to come
The First Doctor would occasionally have premonitions of his future incarnations, (PROSE: A Big Hand for the Doctor) and there was a rumour that he was able to glimpse his first seven regenerations during a game of Eighth Man Bound. (PROSE: Christmas on a Rational Planet, Lungbarrow)

When the First Doctor learned that he was diverted from the South Pole by "forces from the future" to stop him from becoming an incarnation that would play a key role in a future conflict, he was informed by the Player that he would have "lots of new faces" before he regenerated into the incarnation involved in the conflict. (AUDIO: The Plague of Dreams)

Shortly before his regeneration, the First Doctor was told of "a few false starts" before he became the Twelfth Doctor. (TV: Twice Upon a Time)

The Seventh Doctor told his fifth incarnation of a time "all thirteen of [them] teamed up to save Gallifrey", with the Fifth Doctor also showing signs of remembering the incident. (AUDIO: Cold Fusion)

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)

The Sixth Doctor was described as "the rhetorician" by the Doctor's first TARDIS to the Fifth Doctor. (AUDIO: Prisoners of Fate)

(AUDIO: Devil in the Mist)

After losing his body to the Time Lords, made a failed attempt to steal the regenerations of the Fifth Doctor. (PROSE: The Velvet Dark)

The Fifth Doctor was told by Alistair Gordon Lethbridge-Stewart that he had worked with eight other incarnations of the Doctor by 1999, including four of his future incarnations. (PROSE: The King of Terror)

When the TARDIS detected unusual energy signatures which appeared throughout Earth history, including 1984 and 2006, the Fifth Doctor picked a television transmission which indicated that a future incarnation was already investigating 1984, so he went to Brisbane, Australia in 2006 instead. There he met Katherine Chambers who had encountered his future self in 1984 and he used System to send the number “8687” to 1984 as a reminder to his future self about the future he’d encountered in Brisbane. (AUDIO: The Gathering)

Post-regeneration
Whilst on Androzani Minor, both the Fifth Doctor and Peri Brown contracted a fatal condition called spectrox toxaemia. The Doctor gave Peri the only antidote available, saving her at the cost of his own life. He expressed uncertainty as to whether he would regenerate or not, as it felt "different this time". However, he managed to regenerate (TV: The Caves of Androzani) after Nyssa prevented 's interference. (AUDIO: Winter)

The Doctor expressed joy at the change, seeing his sixth incarnation as an improvement over the Fifth Doctor, who he considered unbecoming. Despite having stabilised physically, he suffered initial personality and mental issues that caused him to lapse into extreme paranoia and violence, even trying to strangle Peri. After regaining his senses, the horror of his actions caused him to exile himself on Titan III as punishment until he had attained appropriate humility. On Titan III, he met another Time Lord, his old tutor Azmael. Instead of a self-imposed exile, the Doctor soon became involved with stopping the Gastropod Mestor from launching his eggs into space, which would cause death and destruction on every world they landed on. These efforts cost Azmael his life, as he sacrificed himself to trap Mestor in his own mind to prevent him having the chance to assault the Doctor's still-fragile new persona, but left the Doctor affirmed in his new identity. (TV: The Twin Dilemma)

Dark beginnings
The Doctor set out to fix everything wrong with his aging TARDIS, even succeeding in partially repairing its broken chameleon circuit.

(TV: Attack of the Cybermen) The Doctor later disconnected the chameleon circuit (PROSE: Hall of Mirrors) after the TARDIS continued to shift between an array of problematic disguises, (PROSE: Quick Change) causing the TARDIS to resume using its police box exterior. (TV: Vengeance on Varos)

(COMIC: The Forgotten)

After an unpleasant experience on the planet Rigel IV, the Doctor tried to take Peri to a party in London 1899, but ended up arriving in Africa instead, becoming caught up in the Boer Wars, where they narrowly saved Winston Churchill from an assassin. After spending time in a Boer prison, the Doctor and Peri were able to escape to the TARDIS on the same night as Churchill escaped from the prison. After telling Peri about his last meeting with Churchill in his second incarnation in 1915, the Doctor took Peri to London in 1936 to conduct a follow-up investigation into the apparent temporal interference.

Infiltrating the court using old documentation identifying himself as the Honorary Consul to Santa Esmerelda, the Doctor and Peri reunited with Churchill, posing as their own descendants, hiring former P.I.

After the Doctor and Peri went on a fishing trip, the Doctor felt a time slip in his subconscious where he saw his second incarnation get executed. Upon Peri's suggestion to see a doctor, he went to Space Station Camera to see Joinson Dastari, only for them to find that a massacre had occurred there, with no signs of life. In the service ducts, they found Jamie McCrimmon, who claimed that the Second Doctor had been executed by the Sontarans during a battle on board the space station. After letting Jamie rest, the Sixth Doctor deduced that the Second Doctor's supposed death was an illusion created by the Sontarans. The Sixth Doctor used telepathy to track the Second Doctor to a hacienda near Seville, where he was being held captive while Dastari tried to isolate the symbiotic nuclei in his cells so that the Sontarans could be given the secret to time travel. While Peri distracted the hacienda's occupants, a local woman called Anita helped the Sixth Doctor and Jamie find a secret passageway into the cellars.

The Sixth Doctor sabotaged a TARDIS copy that was being developed on the space station, and lied to Jamie about its workings while he knew the Sontaran Group Marshal Stike was listening in on them. Jamie wounded Stike, and the two of them escaped. Knowing there was another Time Lord present, the augmented Androgum Chessene changed the plan into having Dastari alter the Second Doctor into Chessene's Androgum consort. Chessene also betrayed the Sontarans. The effect on the Second Doctor was not permanent, however, as the condition was not stabilised. The Sixth Doctor, Peri, and Jamie followed the Second Doctor to Las Cadenas restaurant in Seville. Dastari and Chessene had the Doctors and their companions brought back to the hacienda. The Sixth Doctor saved Jamie from being butchered and eaten by the Androgum Shockeye. Dastari then freed the Second Doctor upon realising his mistake in augmenting a primitive Androgum, and was shot by Chessene for betraying her.

His suspicions were proven true: the Master, in a new body, had forced a Carmentine Mind Leech to empty the scientists' minds to feed herself, and set up a trap to lure the Doctor in, so he could empty his mind to fill in gaps in his own memory. The Doctor struck a deal with the Leach, allowing her to feed on his short-time memory to sustain herself, while draining the Master's mind afterwards; while this ruined the Master's plan overall, he gave him enough energy to escape in his TARDIS.

Before he could try and find the human staff of the asylum, the Doctor saw Peri being kidnapped by Adam Mitchell, and quickly remembered how Adam had kidnapped his companions in the past and that "Peri" was actually Frobisher in disguise. (COMIC: Façades) However, Adam eventually caught Peri as well. (COMIC: The Choice)

Following a chronal trail left by the Eleventh Doctor as the Tenth Doctor merged their TARDISes together, the Sixth Doctor joined his other incarnations as they stormed Adam's fortress in Limbo to save their friends from Adam and the Master. Though the Master attacked them with Autons, Frobisher was able to free the captured companions, and they helped the Doctors fight off the Autons, as Adam had a change of heart when the Master revealed he intended to use the chronal energies he had stolen across the Doctor's timelines to destroy the universe. After the Master killed Adam as he foiled his plans, the eleven Doctors honoured Adam as a "true companion". (COMIC: Endgame)

Tracking a distress signal to Marinus, the Doctor, Peri and Frobisher found a dying Time Lord trying to inform them of "Planet 14". Seeking out Jamie McCrimmon in the hope of him recalling where he had heard the name before, the Doctor was reminded by Jamie that they had first heard of Planet 14 during the Cybermen's invasion of London. Returning to Marinus, the Doctor discovered that the planet had been rapid-evolved by a machine known as a Worldshaper.

Realising that Marinus was Planet 14, the Doctor discovered that the native Voord had evolved into Cybermen, prompting him to track down the Worldshaper in the hope of destroying it. However, he discovered that the machine was being guarded by the Cybermen, and was unable to prevent Jamie from sacrificing his life to destroy the Worldshaper. Hurrying back to the TARDIS, the Doctor narrowly escaped a wave of accelerated time, and was greeted by a party of Time Lords. Despite the Doctor's arguments, the Time Lords told him to leave the situation to them, and he dematerialised in disgust. (COMIC: The World Shapers) Shortly afterwards, Frobisher left the TARDIS to resume working as a private detective. (AUDIO: The Maltese Penguin)

Final travels with Peri
After being warned in a dream about time experiments, the Doctor brought Peri to a spaceship called the Vipod Mor and became separated from her after she fell through a ventilation shaft. The Doctor discovered that the ship's computer was planning to cause the Big Bang and avert man's creation in order to prevent their development into a violent race. Before he could intervene, a Time Lord drew him, Peri and his TARDIS away and informed him that this event was always destined to occur. Angry at almost averting the existence of the universe, the Doctor took off to find a library and study up on his history. (AUDIO: Slipback)

Working with his next incarnation, the Doctor and Peri rescued Davros from his trial before the Dalek Emperor on Skaro, using a computer virus to overcome the Daleks guarding him. (COMIC: Emperor of the Daleks!) Onboard the TARDIS, the Doctor spoke with Davros and told him he knew where there was an army of Daleks which he would take Davros to if he promised to programme them with pity and compassion. (COMIC: Up Above the Gods) The Doctor dropped Davros off on Spiridon, as part of his future self’s plan, and then went to Existentialist’s Bar where he met his future self. They toasted to “the future”. (COMIC: Emperor of the Daleks!)

After a series of stressful adventures, the Doctor decided to take Peri to the planet Ravolox to relax. Soon discovering that Ravolox was Earth, moved thousands of light years from its original position, they encountered the primitive descendants of humanity, and prevented L3 robot Drathro from allowing a black light explosion. The Doctor also met conman Sabalom Glitz, who explained that "Ravolox" had been moved to protect the secrets of a "higher species" from the Andromedan "Sleepers". (TV: The Mysterious Planet)

The Sixth Doctor was summoned by his first incarnation, who required the aid of one of his future incarnations to escape a castle in medieval England, where he had been entrapped by knights thinking he was holding Lady Mary hostage in his TARDIS. After the Fifth Doctor lost the game that chose who would face the knights, he explained the situation to them and the Doctors were permitted to leave, but not before Peri bumped into the Fifth Doctor. (PROSE: Five Card Draw)

The Doctor and Peri witnessed Primus Cyberman 9.9P-VIV being destroyed when it overheated to the point of combustion while "raging at the final vestiges of its own humanity". (PROSE: Ghost in the Machine)

The Doctor took Peri to Omnia as it was a remote planet. After learning of an invasion he started to investigate what had happened to the planet. Aldo Rega told him about the war. He was captured by the watchers and interrogated by Carmen Rega. He learnt about the Daleks' plans and that they were mining Vitanium on the planet. The Doctor encountered a Special Weapons Dalek in the mine and realised it was a new type of Dalek. He found a weakness in the type of Vitanium which contained a radiation lethal to the Daleks and used this to defeat them. (AUDIO: Emissary of the Daleks)

The Doctor and Peri encountered Percy Blakeney who thought him to be the Scarlet Pimpernel. Whilst Blakeney was ill the Dcotor continued his work. He was interested on who caused this illness which was anachronistic. He was also concerned as Blakeney was a fictional being. He asked her to also retrieve a gadget he left in France to work out either way. He grew bored on the servants constantly asking about the upcoming ball. He learnt that Blakeney was a time traveller from the future. Percy told him that the Z22 caused the genocide of his race, but he learnt from Tyrax that the android was created to serve justice on Percy for the genocide he caused. He felt betrayed because of this. After Donat almost killed him, the Doctor helped him back to health and put him in a coma on the TARDIS. He took him to his prison cell to serve his sentence for genocide. (AUDIO: Plight of the Pimpernel)

On the planet Thoros Beta, the Doctor encountered Sil, and discovered that he and his fellow Mentors were trying to make deals with a savage king named Yrcanos through manipulating his mind. After a failed attempt to probe his mind to see if the Time Lords had sent him to intervene on their behalf, the Doctor pretended to be on the Mentors' side and helped a scientist named Crozier transplant the mind of Kiv, the Mentor leader, to a deceased Mentor. Though the process was successful, Kiv's mind was unable to adjust to new body, and so Crozier made plans to have Peri's mind overwritten with Kiv's consciousness, which would kill her in the process. Rushing to her rescue, the Doctor was suddenly influenced by the Time Lords, who put him under their control and forced him to board his TARDIS (TV: Mindwarp) and travel to a Time Lord space station. (TV: The Mysterious Planet)

Trial
Upon arriving at a courtroom on the CIA's Space Station Zenobia, (PROSE: The Eight Doctors) the Doctor initially tried to use his status as Lord President to avoid a trial, but was informed by the Inquisitor that he had long since been removed from office due to his perpetual absence. Alerted to the fact that he was the defendant, the Doctor chose to represented himself in the trial, during which he and his prosecutor, the Valeyard, would present events from his life via the Matrix as evidence. The Valeyard proceeded to display his recent adventures on Ravolox (TV: The Mysterious Planet) and Thoros Beta. (TV: Mindwarp) Having been under the effects of partial amnesia due to being taken out of time, the Doctor was unable to defend his actions properly, (TV: The Mysterious Planet) and also suffered an emotional blow when he witnessed what seemed to be Peri's death. (TV: Mindwarp)

The Doctor was allowed to access the Matrix to find evidence for his defence, being assisted by Anosia. Unknown to him, the Valeyard ensured the evidence was tampered with to undermine his case. (PROSE: Interstitial Insecurity) The Doctor presented the case for his defence, offering an adventure from his future, featuring an Earth woman named Melanie Bush as his companion, where he was forced to destroy an artificial race known as the Vervoids. However, the Valeyard seized on this to charge the Doctor for the genocide of the Vervoids, prohibited by Article 7 of the Constitution. (TV: Terror of the Vervoids) The Doctor tried to point out the hole in the Valeyard's claim of genocide; the Vervoids were artificial in nature and never truly alive to begin with.

When the Inquisitor pressed the Doctor to provide evidence against the Valeyard's claims, the Doctor was surprised at the arrival of both Mel and Glitz, who were brought to act as witnesses. Furthering his shock, the Doctor learned that had supplied this aid from inside the Matrix, and that the Valeyard was in fact a manifestation of the Doctor's own inner darkness created "between [his] twelfth and final regeneration". Taking advantage of the confusion, the Valeyard fled into the Matrix. The Doctor and Glitz followed and entered a battle of wits with the Valeyard. However, the Master intervened with this and tried using the Doctor as bait for his own plots. The Doctor overcame this and proceeded to find out that the Valeyard had prepared a weapon to kill all the Time Lords in the court room.

The Doctor defeated him and learned that the Valeyard falsified some of the evidence with the aid of the High Council in a plot to steal the Doctor's remaining regenerations. To his surprise, he learned Peri had not died, but was now wed to Ycarnos as his queen. As the populace of Gallifrey reacted to news of the dishonesty of their High Council, the Doctor left in his TARDIS with Mel. (TV: The Ultimate Foe)

Following an encounter with an older version of himself and a younger Mel in a pocket of cauterised time, (AUDIO: The Wrong Doctors) the Doctor returned Mel to Oxyveguramosa, her original point in time, (PROSE: The Ultimate Foe) after which the Time Lords wiped his memory of much of his trial, on the grounds that it is dangerous for him to know his own future. (PROSE: Time of Your Life)

Pessimistic about his future
The Doctor travelled to Torrok to become a recluse in order to ensure that he would not become the Valeyard. However, the Time Lords manipulated the Doctor into coming out of seclusion to save Earth in 2191 from Krllxk. During this adventure, the Doctor met Grant Markham, who subsequently joined him on his travels. (PROSE: Time of Your Life)

On their first adventure in the TARDIS, the Doctor and Grant arrived on Agora in the year 2191, when it was being invaded by the Cybermen. While Grant helped the human colony on Agora defeat the Cybermen, the Doctor was imprisoned and tortured on a Selachian warcraft. After they left Agora, the Doctor spent weeks in the TARDIS recovering from radiation poisoning sustained on board the craft. (PROSE: Killing Ground)

When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the Sixth Doctor decided to let them argue amongst themselves to distract the pandimensional entity that was trying to use the TARDIS to invade the Earth. He found the locations the entity was going to invade first and sent encoded location vectors via cat photos for his other selves to stop the invasion before it started, and then travelled to his first incarnation's TARDIS to install a button on the console that would expel the entity from the Fourth Doctor's TARDIS, ending the crisis. (WC: Doctors Assemble!)

On BBC3, the Sixth Doctor introduced an episode of Roland Rat: The Series with disdain. After the episode concluded, he cheerfully recommended the viewers to switch over to BBC1 to watch Doctor Who, however Ron Rat insulted the series, causing the Doctor to attempt to kill him in retaliation. (TV: Untitled)

Still tormented by the idea of the Valeyard, (PROSE: The Hard Stair) the Doctor travelled to a bar named Bianca's, and discovered that it was built on the remains of an old TARDIS. There, he fell in love with the bar's star singer, Bianca, who he later learned was an evil future distillation of one of Iris Wildthyme's regenerations who had a similar plan to that of the Valeyard involving stealing the remainder of Iris' lives. After confirming his love for Bianca, almost shooting Iris and causing a time ram, the Doctor and Iris managed to defeat Bianca and her army of shadows and psychic worms. (AUDIO: The Wormery)

The TARDIS landed in a museum in the city of Excelis on the planet Artaris. The Doctor attempted to free a thief from the security system, but was forced to hide in his TARDIS while the wardens searched the building. He was arrested shortly afterwards on a suspicion of thieving, but succeeded in convincing the officers of his innocence, immediately before he met Reeve Maupassant, who he recognised as Grayvorn. The Doctor discovered that, after his fifth incarnation saw the Mother Superior and Grayvorn fell from the convent bell tower, the Relic merged Grayvorn and the Mother Superior's minds into one, making Grayvorn immortal at the cost of ever being able to sleep.

Realising that Grayvorn was behind the raid, the Doctor reasoned that he had intended to use a failed theft of the Relic as an excuse to claim it for himself under the guise of protecting evidence. However, just as Grayvorn tried to open the Relic to transfer the second soul into a new host, he was distracted by Danby, an Inquisitor who had been helping the Doctor's enquiries, giving the Doctor the chance to open the Relic on Grayvorn and dispel him from his physical form, whilst simultaneously absorbing the Mother Superior into it. (AUDIO: Excelis Rising)

After another reclusive period, the Doctor travelled to ancient Greece where he met Plato and had an adventure with the Spindle of Necessity and an alien race called the Fates. After being told that becoming the Valeyard was but one possible future, the Doctor was heartened to continue his travels. (PROSE: The Spindle of Necessity)

Optimistic travels
While travelling alone, the Doctor was drawn back to the Halloween party at the old house he had visited in his first incarnation, and was made to believe that the First Doctor had never left the house and his experiences ever since had been fabricated by the Celestial Toymaker. Though doubting his own existence, the Doctor challenged the Toymaker to a game of "two truths and one lie", which revealed that the Toymaker was lying. Creating a no-win situation in the game that prevented the Toymaker from giving an answer, the Doctor escaped in his TARDIS, and left the Toymaker trapped in his domain. (PROSE: Trick or Treat)

The Doctor investigated a series of murders committed by a shapeshifting Logovore in Hogarth City, (PROSE: Death Sentences) walked past a splinter of Clara Oswald in a corridor that resembled his TARDIS, (TV: The Name of the Doctor) saved a busload of semi-comatose people, (PROSE: Pass It On) and defeated the Krotons. (PROSE: Alien Bodies) Visiting the planet of the Kuskaroo, the Doctor repelled an invasion by the Galyari, adopting the title of "the Sandman" in an attempt to scare them off. When all else failed, he resorted to destroying their Shushkubra, inadvertently imprinting himself onto the Galyari consciousness. (AUDIO: The Sandman)

Arriving in Birmingham in the 1980s, the Doctor was horrified to witness a witch trial in progress and sought to end it, only for the accused witches to reveal themselves as Carrionites. The Carrionites rampaged, teasing the Doctor about his future as the Valeyard which he retorted was just a possibility. The Doctor worked with Katy Bell and her father Douglas to stop the Carrionites, aided by information in a book written by George Litefoot, and they succeeded at the cost of Katy’s life. (AUDIO: The Carrionite Curse)

Along with seven other incarnations, the Sixth Doctor became trapped in the Void when it began to attack and devour the universe. He and the others were able to form a dimensional bridge to allow the Eighth Doctor to escape, and were then joined by the War Doctor, followed shortly by the 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)

The Doctor visited a bed and breakfast surrounded by an impenetrable fog, and discovered that the owners, Chloe and Arthur, were killed by versions of themselves every night, only to wake in their beds the next morning, and now he was destined to share in this fate. After over a month of trying, the Doctor managed to persuade the couple to escape the loop by refusing to go outside and be killed. (PROSE: The Death of Me)

Unravelling Peri's fate
Attempting to brew a pot of tea, the Doctor was interrupted by turbulence caused by the TARDIS becoming caught in another vessel's wake. Crash landing on a barren planet, the Doctor was attacked, only to be awakened by Peri, who revealed that they were on a planet called Refiloe, where she had become stranded after fleeing her unhappy marriage. The two discovered the Doctor's TARDIS was emitting a dangerous form of temporal energy that was ageing the people of the planet into dust. While investigating, Peri contracted a deadly disease and died. Furious, the Doctor set about to uncover the plot he was being tangled in, and discovered that everything that had happened after his arrival had been a hallucination and that he was hooked up to a dream machine, with the demises of Peri and his TARDIS being used to lure the Doctor into committing suicide. (AUDIO: Her Final Flight)

The Doctor searched for Peri in her hometown. (PROSE: Have You Seen...?)

Recalling an adventure he had had in his fifth incarnation, the Doctor travelled to Los Angeles, 2009 to meet a version of Peri who was transported to Earth, with all her memories of travelling in the TARDIS wiped. During an adventure involving the Piscons, the Doctor and Peri discovered that due to the manipulations of the Time Lords, five alternate Peris existed simultaneously in the universe. After this encounter, the Doctor offered Peri the chance to return to the TARDIS, but she declined. (AUDIO: Peri and the Piscon Paradox)

The Doctor arrived during the middle of a war on Cawdor, and discovered a plot by a figure called "Tenebris" to use a secret weapon called the Acheron Pulse. However, discovering that Tenebris was an old acquaintance, Kylo Sorsha, the Doctor foiled his plan and gave him a second chance. (AUDIO: The Acheron Pulse)

Travelling with a historian
Tracking a nexus point distortion, the Doctor encountered university lecturer and historian Evelyn Smythe. Realising her importance to the timelines, the Doctor allowed her to come with him back in time to stabilise the nexus point and save her life. Upon doing so, Evelyn insisted on joining the Doctor on his travels, as she did not want to pass up the opportunity to explore history first-hand. (AUDIO: The Marian Conspiracy)

Arriving in Lanyon Moor, the Doctor once again met his old friend Alistair Gordon Lethbridge-Stewart and uncovered a slew of unsolved mysteries that centred around the malevolent work of a stranded Tregannan named Sancreda. Sancreda had been trapped on Earth for many millennia, and, upon awakening, tortured and destroyed several humans with his psionic powers. Discovering that he had not been abandoned as he had believed, and that instead he had caused his brother's accidental death, Sancreda threatened to destroy the Earth in a fit of rage, prompting the Brigadier to trick him into causing his own demise before he enacted his wrath on the entire planet. (AUDIO: The Spectre of Lanyon Moor)

While Evelyn was trapped in the TARDIS, (PROSE: Instruments of Darkness) the Doctor was dragged into the Kurgon system, where he encountered a time distortion that killed everyone but himself, a waitress named Ellie and the android pilot Azimendah. After the Doctor realised that the mythical Temperon was connected to the time distortion, Azimendah was killed by Ellie, who revealed herself to be of the Sirens of Time, and the Doctor was trapped in his TARDIS after accidentally freeing the Knights of Velyshaa, but saved by the Temperon, who took him to Gallifrey to meet with his fifth and seventh incarnations. The Doctors were almost tricked into undoing their altercations to history, but they instead released the Temperon from the Knights of Velyshaa so that it could trap the Sirens of Time in an eternal struggle. With the Sirens of Time's manipulations to history averted, the Sixth Doctor was returned to his proper place in time by the Seventh Doctor. (AUDIO: The Sirens of Time)

Caught in a temporal wake, the TARDIS brought the Doctor and Evelyn to Archetryx where a conference between numerous temporal powers was being held. He met with the Time Lord delegation, consisting of the Acting President and Vansell, who informed him that President Romana had disappeared whilst investigating Etra Prime twenty years ago. The Daleks attacked the conference, during which the Doctor deduced the temporal wake was Etra Prime itself on a collision course with Archetryx. As he tried to raise the defences, he was reunited with Romana, who had escaped from Etra Prime after tweny years as a Dalek slave. Just before Etra Prime collided with Archetryx, he escaped in the TARDIS with Evelyn and Romana. He hurriedly took Romana back to Gallifrey and upon arriving in the TARDIS cradles they discovered Daleks had landed on Gallifrey and were massacring the ceremonial guards. Reaching the security centre, the Doctor altered Gallifrey’s security so Evelyn’s retinal pattern was needed to open the doors. As he, Romana and the Acting President planned their next mind they were contacted by a Black Dalek, which revealed the Daleks had developed the Apocalypse Element and were primed to unleash it in the Seriphia Galaxy. The Doctor and the President called its bluff, believing no lifeform would dare unleash such a thing, but were horrified when the Dalek followed through with its threat. The Doctor and Romana attempted to use the Eye of Harmony to contain the effect, but it proved insufficient. After this failure, the Doctor lost his temper with Evelyn, proclaiming she could not possibly understand the scale of the destruction unfolding. The Acting President allowed the Dalek spearhead access to the Eye after they offered help and to the Doctor’s surprise they did help contain the devastation in a separate continuum to burn out safely, at the cost of their lives. Afterwards, the dying Black Dalek revealed to him this was their plan all along, as Seriphia had now been reborn into thousands of virgin worlds which the Daleks were primed to seize. The Doctor and Evelyn quietly departed the recovering Gallifrey. (AUDIO: The Apocalypse Element)

Visiting the Galápagos Islands as a treat for Evelyn, the Doctor teamed up with Charles Darwin and two residents named Greta and Emilio Rodrigues, working together to defeat an insane Silurian scientist named Tulok, whose experiments had provided the evolutionary leap from ape to man.

Stopping for food in the south of England, the Doctor and Evelyn met Amelia Doory and Reggie Mead, a couple apparently experimenting with finding a cure to their contamination with vampire DNA. On their trail was a vampire named Nimrod, head of a secret Black Ops organisation called the Forge, who managed to hunt the pair down in an effort to correct the failed experiment he had conducted decades earlier, code-named Project: Twilight. Evelyn befriended a young mother named Cassie Schofield, while the Doctor helped Amelia perfect a cure to stop their mutation, only for Amelia to betray the Doctor and turn the cure into a superior virus, first infecting Cassie, before fleeing to infect the rest of the world. Nimrod teamed up with the Doctor to stop Amelia, blowing up Amelia's blood bank, while the Doctor pursued her, knocking the virus into the water of the River Thames, prompting her to dive for it and drown. The Doctor took Cassie to Norway to live in secret while he developed a cure for her condition. (AUDIO: Project: Twilight)

After attending a funeral, (AUDIO: Real Time) the Doctor and Evelyn joined an expedition group investigating an ancient Mayan temple on the planet Chronos after being informed of a distress call mentioning Cybermen.

(AUDIO: The Crimes of Thomas Brewster)

While they were travelling in the Time Vortex, the Doctor and Evelyn managed to disarm Brewster, and change course before they arrived at their destination. The Doctor justified his actions by saying that if Brewster returned to his own time, then using his future knowledge would cause chaos and anarchy.

According to this account, both the Doctor and Evelyn parted on bad terms. (PROSE: Instruments of Darkness)

Old acquaintances
Saddened by Evelyn's absence, the Doctor travelled to 1987 Pease Pottage to officially meet Melanie Bush. However, an earlier version of himself arrived with the older Mel from after his trial, causing confusion while battling Stapleton Petherbridge. It soon became clear that Petherbridge was an alien who had created a fake Pease Pottage and isolated it outside of time, in an attempt to trap the Doctor.

The two Doctors and the two Mels defeated Petherbridge, resulting in the younger Mel's death. Noticing a discrepancy in the timeline, the Doctor used Petherbridge's technology to alter events, putting her back in the real Pease Pottage in 1987, while his younger self decided to deposit the older Mel on Oxyveguramosa, where she was taken from by the Time Lords during the trial.

Going to investigate the Valeyard's activities on Etarho, the Doctor found what appeared to be him in his final incarnation, only for Darkel to arrive and frighten the man into a mud hole, where he drowned. Darkel then demanded the Doctor to open the Valeyard's Black Scrolls, but he refused. The Valeyard, who had been the "future Doctor" all along, then emerged from the mud hole and revealed that he had planned the entire trial to lure the Doctor and Darkel into a death trap. Powerless to prevent his escape, the Doctor and the other Time Lords fled the planet moments before it was destroyed. (AUDIO: Trial of the Valeyard)

The Doctor reunited with Frobisher in the 82nd century, where he had resumed his job as a private detective, and was investigating mysteries. After solving a case involving Josiah W. Dogbolter, Frobisher was encouraged by his ex-wife to travel with the Doctor again. (AUDIO: The Maltese Penguin)

When the Doctor and Frobisher landed in a Medieval castle after the crowning of Pepin VI, they were dubbed as angels. They meet Eugene Tacitus who had recorded all events and glamorised them in a Bible. The Doctor realised that the castle and its inhabitants were part of a fictional reality as a means of self-torturing escapism after Eugene had murdered his sleeping son. (AUDIO: The Holy Terror)

During their adventures, the Doctor and Frobisher met Sabalom Glitz whilst on the run from bounty hunters, (PROSE: Mission: Impractical) granted Stuart Mallory his wish to see an emperor penguin, (PROSE: The Last Emperor) and encountered the descendants of a Peri that married Yrcanos and defeated a Nahrung which had possessed a regent named Farlig. (COMIC: The Age of Chaos)

The Doctor stopped Beep the Meep when he took over Roger Lowell to gain a massive viewing audience and hypnotise them with subliminal messages on Audience Shares and command to kill on Beep and Friends. The Doctor claimed he had already disabled the subliminal messages. When Beep then tried to kill Lucy and Todd, the contestants on Audience Shares, he discovered that the Doctor had only disabled his laser pistol. The subliminal message went out when it looked like Beep was murdering the contestants, turning the audience against him. (AUDIO: The Ratings War)

The Doctor was arrested and faced execution on the planet Baspral by an Inquisitor due to the fact that he had saved a young boy's life on his last visit, allowing him to become a vicious dictator who caused billions of deaths, something the Inquisitor held the Doctor responsible for. However, the Doctor showed him that the slaughter the population had suffered strengthened the people of Baspral, who went on to defeat a Dalek attack force, saving the whole universe. After this, the Inquisitor released the Doctor, and the Doctor saved the Inquisitor from execution in return. (PROSE: The Inquisitor's Story)

New friends
The Doctor set up a quarantine for Horlak and his Silurian scholars when they became infected with Raldoma Syndrome, (COMIC: The Lost Dimension) and lost a fight with a Logovore, resulting in his memories of Edward Grainger being taken. (PROSE: Death Sentences)

The Doctor went on the trail of a parasite known as "the Darkness", and arrived on Earth, where he was saved from a mugging by UNIT officers Will Hoffman and Emily Chaudhry. Aided by Will, Emily and UNIT, the Doctor stopped the Darkness from influencing the human population into murdering their loved ones. (PROSE: The Terror of the Darkness)

Planning to take Emily and Will home in the TARDIS, the Doctor got sidetracked by a distress signal, leading him to an army base in World War II and a reunion with Edward Grainger. The two old friends worked to return a Mim back to its home world. After this, the Doctor witnessed the birth of Edward's son, John. Preparing to take Emily and Will home, the Doctor received a mission to travel to 1957 to investigate discrepancies in the UNIT archive. (PROSE: Incongruous Details)

Arriving in 1957, the Doctor discovered his whole history of defending the Earth had been wiped off the record at the Ministry of Defence by a British government agent called Ronnie Tillyard. After this, the Doctor finally returned Emily and Will home. (PROSE: Defining Patterns)

Arriving during the French Revolution in 1789, the Doctor rescued a man named Jason from death by the guillotine, and allowed him to become his new companion. (AUDIO: The Ultimate Adventure) The Doctor took Jason to Metebelis III in the Acteon Galaxy, (AUDIO: Beyond the Ultimate Adventure) before receiving a summons from Margaret Thatcher in 1988. The Doctor and Jason defeated a plot by the Daleks and the Neomorph Cybermen to kill the Doctor and destroy the TARDIS. This led them to arrive in Bar Galactica, meet Madame Delilah and Karl the Dalek mercenary, and to return to the French Revolution. During this adventure, they were helped by Crystal and Zog, whom the Doctor invited to join them on their travels. (AUDIO: The Ultimate Adventure)

The Doctor, with Jason, Crystal and Zog visited Leisureworld on the living planet, Krennos, where they uncovered a plot by the Chameleons. (PROSE: Face Value)

After Zog left the TARDIS crew, the Doctor, Jason and Crystal were summoned by Karl to Bar Galactica to attend Madame Delilah's funeral. After this, Karl sent the TARDIS crew on a quest for treasure on the icy world of Ultima Thule in an obscure dimension, where they met a being who called itself the Eidolon. The Doctor managed to convince the Eidolon that he would do its bidding, but tricked it into entering the TARDIS, which he had set up to go straight to Gallifrey, where the creature could be dealt with. (AUDIO: Beyond the Ultimate Adventure)

The companion from the future
While travelling alone, the Doctor picked up a distress signal from a desert island in the year 500002. (AUDIO: The Condemned) There, he rescued a young girl named Charley Pollard. (AUDIO: The Girl Who Never Was) Together they landed in a hotel room on 29 February, 2008 and found a dead body. While trying to investigate the death, the Doctor and Charley encountered DI Patricia Menzies prior to their earlier meeting. She believed that the Doctor was the murderer, but he managed to convince her that he was a time traveller, prompting the pair to team up. Investigating further, they realised that an alien named Robert Slater had let slip a case full of a strange new toxin that bonded its victims to the building itself, and that it had infected a man named Sam. The Doctor was too late to save Slater from Sam's wrath and reluctantly took Charley on as his companion. (AUDIO: The Condemned)

After Charley accidentally alerted the Library of Alexandria to an overdue book in the Doctor's possession, the duo landed in the family tomb of the Doomwood family. There, they learned of a mysterious curse that loomed over the family and before long, one of its members died. Charley became influenced into thinking that she was the bride of a nobleman before turning into Gypsy Charlotte, a highway robber partnered with Dick Turpin, a character in the novel they were planning on returning. The Doctor followed on horseback and realised that Charley had the Doomwood curse. He followed Charley and Dick to York where he learned that the particles that were making up the fiction were spreading and that before long, everyone would become possessed by fiction. Realising that the only way to save Charley was to surrender to fiction, the Doctor took on the personality of a fictional character and met up with Charley, who snapped out of her trance and freed him too. (AUDIO: The Doomwood Curse)

After landing on an unnamed planet which looked like a manor house with servant cottages, Charley and the Doctor were chased by werewolves. When Charley fell into a pit trap, he went to find a branch to get her out of it. However, he was found by Lina and Arin and taken to their leader. Lina and Arin took him to a party where he watched the partygoers turn from werewolves to proto-humanoids, which he found interesting as it was opposite to all the tales he had heard throughout his travels. When the police came, he tricked them into walking into the light to help his new friend's escape. Ugo explained to the Doctor the history of his species and how the humans on the mainland wanted to stop the werewolf condition. He then organised a way to stop Paignton. When the containment protocol was launched, he wanted to save all of the islanders from a nuclear bomb. However, because of the Valeyard's intervention, the bomb exploded out at sea, and the Doctor suggested that all of the islanders set sail for another place so that the humans would think that they were destroyed. (AUDIO: The Red House)

After apparently landing on Spiridon, the Doctor and Charley encountered a group of Thaleks, Thals who thought they were Daleks. He discovered that this was an experiment that Murgat was doing with the Thals and the Kyropites. (AUDIO: Brotherhood of the Daleks)

After preventing the resurrection of a Kroton army on the colony world Onyakis, (AUDIO: Return of the Krotons) the Doctor and Charley travelled to 2008, where they once again encountered DI Menzies. Investigating a pound coin from 2012 that had appeared in a coin-operated vending machine four years too early, the duo discovered a secret gambling operation and were caught in the middle of a war between the Cyrox and the Tabbalac, two races who were using Earth as their battleground. After the war was ended, Menzies asked the Doctor if she could travel with him. The Doctor politely refused; citing the growing mystery surrounding Charley's true identity, but indicated that one day he might take her up on the offer. (AUDIO: The Raincloud Man)

The Doctor became suspicious of Charley's secretiveness and eventually confronted her, only for her to collapse in the TARDIS and fall into a long-lasting coma. Placing her in the Zero Room to recover, the Doctor discovered that Charley had been infected with a virus and spent several years trying to cure her.

After tracing the virus to the Amethyst Viral Containment Station, the Doctor became caught in the crossfire of a battle between an invading force of Daleks and the mysterious creators of the facility, the Viyrans. The Daleks were trying to find Patient Zero. Charley woke up in the TARDIS and confronted a strange woman that seemed to have a large amount of knowledge about the Doctor. This person identified herself as Patient Zero and confessed that she had infected Charley with the virus. The virus was created to turn infected people into copies of whoever infected them. Patient Zero had been experimented on by the Daleks and infected with the virus.

She snuck abroad the TARDIS while the Doctor was being chased by them and had remained in the TARDIS ever since. While the Doctor took care of the Daleks, Charley discovered that Patient Zero, whose true name was Mila, was transforming into a copy of her, as she infected Charley. Mila had planned to take over Charley's life by transforming into a replica of her. Unable to stop her, Charley faded out of existence while Mila took her place. (AUDIO: Patient Zero)

The Doctor received a summons from an old deceased friend and travelled to Draconia. There he discovered a conspiracy involving the new crown prince of Draconia, his mother and an army of paper soldiers that were used by the previous kings of Draconia to amuse themselves while they drifted in their tombs in space. (AUDIO: Paper Cuts)

After travelling for several months, the Doctor and Mila landed in an alternate timeline created by the Viyrans' attempt to remove a virus from Earth's population. Here, the Doctor discovered that Mila wasn't the real Charley, and Charley had been found and cured by the Viyrans, whom she helped for several millennia in their quest to expunge all the viruses which had escaped from the Amethyst station. After Mila sacrificed herself to save the Doctor and the Earth, Charley revealed her identity to the Doctor, and pleaded with him to allow her to restore the Web of Time. To make him want to forget his travels with her, she told him of the truth of her situation, and her belief that she knew how he would die. He accepted, and she used the Viyrans' memory-altering technology to replace the Doctor's memories of their travels together with fabricated ones of Mila in their place. (AUDIO: Blue Forgotten Planet)

The Land of Fiction
Arriving in what appeared to be Scotland, the Doctor was seemingly reunited with an apparently amnesiac Jamie McCrimmon who had no memories of his travels with the Doctor. The Doctor and Jamie tried to discover why there was Oil Pump Jacks in Scotland in a century where they shouldn't exist, and discovered that the Red Cap's master was trying to exploit the "Black Water" for his own ends. After this adventure, Jamie accepted the Doctor's offer to travel with him. (AUDIO: City of Spires)

Making their way back to where they had left the TARDIS, the Doctor and Jamie discovered that it had been dragged somewhere else. Following the tracks, they had to cross a set of quick sands and encountered the Kelpie who tried to drag them under. They were rescued by Merodach who gave them hospitality, but later accused the Doctor of Witchcraft. The Doctor was then tortured as Merodach wanted the secrets of the TARDIS. Jamie rescued him but then Janet, Merodach's servant, set the TARDIS alight. However, the Doctor was able to use the Kelpie to help put out the unnatural flames. (AUDIO: Night's Black Agents)

They later apparently landed aboard the RMS Titanic. When the Doctor noticed that there was something wrong, such as the song that played during its sinking, the ship became the Titan, which soon hit the iceberg. The Doctor was stranded on the iceberg, but was rescued by the Nautilus by Captain Nemo who was hunting a squid that produced the "Black Water". Nemo later drove the Nautilus into a whirlpool the Doctor and Jamie were left in a white void. (AUDIO: The Wreck of the Titan)

The Doctor and Jamie soon discovered that they had been in the Land of Fiction all along, and that Jamie was a fictional character created by Zoe Heriot, the new Master of the Land, as a mystery for the Doctor to solve. Discovering that they were being used by Zoe to combat an invasion by the Cybermen, the duo managed to defeat them. After their adventure, Jamie decided to remain in the Land, telling the Doctor to seek out the real Jamie if he ever found himself in the Scottish Highlands again. The Doctor returned Zoe to the Wheel, saddened at the fact that she would once again fall under the Time Lords' conditioning and lose all memories of him. (AUDIO: Legend of the Cybermen)

Stranded in Victorian London
The Doctor crash landed in Victorian London during the 1890s due to the temporal experiments performed by Professor Elliot Payne, which caused him to become stranded. Using the alias "Professor Claudius Dark", the Doctor attempted to investigate Payne and his experiments, (AUDIO: The Hourglass Killers) locating and attempting to convince Johnny Skipton of Payne's intentions. (AUDIO: Dead Men's Tales) However, the Doctor discovered that Henry Gordon Jago, George Litefoot and Leela were already investigating the incidents, (AUDIO: The Hourglass Killers) and tried to contact them. (AUDIO: The Man at the End of the Garden) Unsuccessful, he resolved to work on the TARDIS, (AUDIO: The Hourglass Killers) employing the services of an electric supplier. (AUDIO: Chronoclasm)

After Jago, Litefoot and Leela successfully stopped Payne and his temporal experiments, the Doctor found he was still trapped on Earth, and discovered that he was now stuck due to the interventions of Mr Kempston and Mr Hardwick, who had also crashed on Earth due to Payne's experiments. The pair was set on stealing the TARDIS in order to gain access to more advanced time travel equipment, prompting him to sink the TARDIS into the Thames embankment to avoid its location. (AUDIO: The Hourglass Killers)

Inviting Jago and Litefoot to meet him and help him investigate Kempston and Hardwick, the Doctor chose not to reveal his identity, raising Jago and Litefoot's suspicion. (AUDIO: Chronoclasm) Warning them of the approaching Sandmen, they fled, but he was recognised by Leela, prompting him to make the suggestion that she recommend they all go to Brighton. (AUDIO: Jago in Love) However, this failed to work out, necessitating the Doctor to give them all tickets to Oscar Wilde's new play, A Woman of No Importance, where they had an adventure with Wilde. (AUDIO: Beautiful Things)

The Doctor arrived in time to save Jago and Litefoot from a train trapped in a time loop caused by Kempston and Hardwick, where he revealed his true identity to them. (AUDIO: The Lonely Clock) With their help and Leela, the Doctor discovered that Kempston and Hardwick were members of the crew of a crashed Temparon vessel. But Kempston and Hardwick had predicted this and created a trap in Bedfordshire to capture him so that he couldn't stop their plan. Returning to London, the Doctor devised a way to defeat them. After retrieving his TARDIS and seeing Leela off, the Doctor offered Jago and Litefoot the chance to travel with him in the TARDIS, which they accepted. (AUDIO: The Hourglass Killers)

Voyages with Jago and Litefoot
On their first trip through space and time, the Doctor took Jago and Litefoot to Venus in the far future, where they discovered the corrupt Venusian Queen Vulpina was enslaving the young of the Cytherians, the native Venusian race, which they called the Thraskins. Together, they defeated Vulpina and freed the young Cytherians, resulting in a peaceful treaty between the Cytherians and Venusians, before departing. (AUDIO: Voyage to Venus)

Intending to return to London, the TARDIS instead arrived on 1590 Roanoke Island, where the Doctor, Jago and Litefoot were held hostage by a local tribe of Native Americans. They discovered that the tribe were being terrorised by a group of ethereal children, who had been present for four hundred years. Whenever they kidnapped natives, they would leave behind the word "Croatoan" inscribed in the place where they once were. The trio discovered that Croatoan was an island, which they planned to explore, and were galvanised into action when Jago disappeared.

Arriving on Croatoan Island, they found Jago and discovered the TARDIS, which had been on Croatoan for four hundred years. Discovering Jago's captor, he revealed himself to be Sir Walter Raleigh, who had discovered the TARDIS while the Doctor and Litefoot were venturing to Croatoan. After tampering with the controls, Raleigh travelled back four hundred years, and encountered a group of alien beings, who would later become the children who had terrorised the tribe. He taught them how to live and hunt and, in return, they extended his life. However, the Doctor managed to communicate with the Native American Wanchese in the TARDIS, four hundred years prior, who prevented Raleigh from travelling in the TARDIS and restored the timeline. After the aliens disappeared, the Doctor encouraged the now paradoxical Raleigh to step outside and see the true fate of the settlers before he ceased to exist, and dematerialised. Finally managing to return to the Red Tavern, the Doctor bid his farewells to Jago and Litefoot, and set out to discover what had caused the disturbances in the Vortex. (AUDIO: Voyage to the New World)

Travelling with Flip Jackson
Tracking Davros and the Daleks to 18 June 1815, the Doctor learned that they were plotting to change history by helping Napoléon Bonaparte win the Battle of Waterloo. He used Davros' mind exchange machine to switch bodies with him to try and attempted to reform the Daleks, but Davros escaped and reunited with one of the Doctor's former associates, Flip Jackson, and her boyfriend Jared. Convincing Flip that the Doctor she had been accompanying was an impostor, the Doctor managed to gain her aid, while Davros convinced the Daleks of his identity. Together, the Doctor and Flip tricked the Daleks into thinking that he was Davros and showed Napoleon their true nature, prompting him to surrender. Afterwards, Flip asked the Doctor to allow her join him, something he accepted. (AUDIO: The Curse of Davros)

Sitting down to watch cricket on his Time-Space Visualiser, the Doctor and Flip encountered a disturbance which trapped Flip in another dimension. The Doctor tracked the signal to the planetoid Transmission, where he found Porcians attempting to steal a new television station's Reality Generator, a device that could project recordings into reality. Flip was caught in the movie dimension, but, due to sabotage, the dimension's villain, Lord Kran, escaped into reality and started to invade it. The Doctor used the Reality Generator to create a bomb that would destroy any fictional aspects, but leave anything that belongs in reality alone. (AUDIO: The Fourth Wall)

The Doctor and Flip transmatted to Earth in 16127 to see how the planet was getting on. Arriving in Scotland, they befriended a family, only for the Transmat system to become inactive. Detecting the presence of the Wirrn, the Doctor arranged for Flip to hang-glide to the nearest city to warn them. She crashed, prompting the Doctor to go and look for her. The Wirrn awoke and began attacking, but the Doctor used the Transmat system to freeze them under the surface of Loch Lomond. (AUDIO: Wirrn Isle)

The Doctor took Flip to see the New Regency Theatre, but when they found it was closed, he instead brought her to meet Henry Gordon Jago and George Litefoot in the Red Tavern. Litefoot showed him some of the bodies of aspiring actors who only recently had gone missing, but looked as if they had been dead for many years. At the mortuary, the Doctor saw the clothes they were wearing looked like clothes which Adric, Nyssa and Tegan Jovanka wore at the time of his fourth regeneration, and discovered that the Valeyard had rented out the theatre as was he re-enacting his previous regenerations. He went back to the Theatre, where he managed to stop the Valeyard from killing Jago and Ellie Higson. The Valeyard then used the anger and fear in the Doctor's mind to rejuvenate himself. Flip successfully saved the Doctor and in turn overcame her stage fright by performing nursery rhymes onstage. (AUDIO: Stage Fright)

The Doctor and Flip landed in a mine in Chihuahua, Mexico, 2010s after detecting some strange particles which contained Artron energy. There they discovered that the another version of themselves were the source of the signal, being frozen in time. Thinking that these were a future version of them, the Doctor realised that the other Doctor had trapped the cyborg. The Doctor then realised that the other Flip was actually a past version of her. The past version of the Doctor came to save the day to stop the cyborg. He lost his short term memory by being splashed by the Vortex Ice. (AUDIO: Vortex Ice)

The Doctor decided to take Flip to Festin to see the auroras there. After seeing the fire at Khoralia, he went to find help but Halus thought he had caused it. After learning from Halus that the air car tracks went into the ionosphere of the planet, he thought that the Cortex was deliberately wanting to kill its people when the shock of the nearby stars nova reached the planet. Flip managed to bust him out prison to help stop the airways. Learning about the Urge from Dakeem, the Doctor tried to negotiate with it and discovered it came from an alternative dimension, and that it wanted to destroy the planet to allow it to become a physical being again. Whilst Flip was disrupting the traffic, the Doctor used the TARDIS to blot out the sun, as the Urge was using its energy to carry out its plan. (AUDIO: Cortex Fire)

While resting on Tranquility, the Doctor and Flip received a distress signal from another TARDIS, which the Doctor traced to Earth in the 24th century. However, this signal was a trap arranged by Sil using Anzor's TARDIS, as Sil wanted access to a Time Lord to try and copy their remarkable ability to cope with disease as part of a plan to reduce Earth's population to a more manageable level via a series of plagues. Despite the involvement of Cordelia Crozier, who blamed the Doctor for the death of her father, and the involvement of the Velandari, a race of sentient diseases, the Doctor was able to turn the tables on Sil and force him to flee Earth while Cordelia destroyed Sil's allies. (AUDIO: Antidote to Oblivion)

The Doctor landed near Erys to calibrate the TARDIS' controls. Shortly afterwards, the TARDIS was attacked by the Drachee, who Flip allowed onboard, greatly annoying the Doctor. He was incapacitated as Flip was kidnapped. He later rescued Sarra Vanser from her collapsing space yacht. After making his way to Erys, the Doctor discovered it was a sentient moon and learnt that it could read minds and wanted to know of their stories. He discovered that Renval was created by Erys which were created from the integrated people. The Doctor then played with Erys' brain to stop it attacking him and his friends. (AUDIO: The Brood of Erys)

The Doctor brought Flip to the Nelson Mandela International Space Station, where Salvage 2 collided with the station, separating the pair. The Doctor went to mission control to find a way to save Jyoti Cutler and Flip by manipulating a set of satellites to move them back to the Mandela. Instead, he woke up the Scavenger, which started to move about. When he wanted to rescue Flip, he learned that she was in the Scavenger. Realising that Scavenger was intelligent enough to provide air for Flip, the Doctor talked to Flip and learnt that Anarkali was still on board. He tried to distract Flip when missiles were aimed at the ship, and got Scavenger to move away to find Atlantis. He tried to stop Flip from accessing the Transmat but he failed and she transmatted back to her original location. He asked Jyoti to locate Flip in orbit, however, she wasn't there. (AUDIO: Scavenger) The Doctor bent space and time with the TARDIS to slow Flip's descent, and then returned her to Jared. He later received an invitation to their wedding. (AUDIO: The Widow's Assassin)

Reunited with Peri
After leaving Flip in 2012, the Doctor found a version of Peri who married Yrcarnos, and was imprisoned by her as retribution for leaving her on Thoros Beta. After Yrcarnos died from poisoning, the Doctor declined to investigate, as Peri had not asked him too, but looked into the matter in private, and discovered that Peri had poisoned Yrcarnos, leading the Doctor to believe that Lord Kiv had successfully transferred himself into Peri's body.

After five years in prison, the Doctor was finally pardoned and made Peri's royal adviser. Accompanying her on a royal visit, the Doctor was accused of murdering Peri when she collapsed from a poisoning, but he was able to keep her alive. Following a second murder, and after switching minds with Peri, the Doctor discovered it wasn't Kiv in Peri's body, but Mandrake, his childhood imaginary friend. The Doctor defeated Mandrake inside Peri's mind, while Peri, in the Doctor's body, managed to get him back to the TARDIS and trigger the antidote to cure her body. The Doctor then offered her the chance to travel with him again. (AUDIO: The Widow's Assassin)

On their first trip in the TARDIS together, the Doctor and Peri arrived in Scotland during the 22nd century Dalek invasion. He had to rescue Peri when she was taken as a slave worker and stole Kyle Inskip's bike to do so. Helping Moira Brody and Peri to escape, they made their way to the Orkneys. He became worried when Peri became infected with a Varga plant. Eventually he was recaptured and disovered that Moira was a Roboman Elite but he had to destroy that research to maintain the timelines. (AUDIO: Masters of Earth)

The Doctor and Peri then visited the College of Advanced Galactic Education so that the Doctor could receive an honorary degree in moral philosophy. He was worried about why he was sent one and decided to investigate. They ran afoul with the Second Rani, who wanted the Doctor to be part of her machine which contained the most intelligent students that she wanted to use to re-engineer Chaos theory. (AUDIO: The Rani Elite)

Companionless travels
The Doctor tracked Ulrik to the site of an early Dalek battle between Ulrik's ancestors and the Daleks. He convinced Ulrik to trust him, turn a Roboman under his control and meet him on the roof of the building. There, the Doctor used his TARDIS to transport the Dalek Prime and Ulrik backwards in time. The Doctor joined his fifth, seventh and eighth incarnations briefly before being returned to his own timeline. (AUDIO: The Four Doctors)

Attempting to help a pair of renegades from a race of otherwise xenophobic shapeshifters escape from Mykloz, an assassin sent by their rulers, the Doctor's efforts were briefly complicated by the presence of his first incarnation, as Mykloz attempted to frame the First Doctor as an impostor, but the Sixth Doctor was eventually able to escape and help the fugitives escape while expelling Mykloz into a dimensional rupture. (PROSE: The Golden Door)

The Sixth Doctor teamed up with all of his other incarnations to save Gallifrey from destruction at the end of the Last Great Time War, (TV: The Day of the Doctor) even joining them on the surface of the planet to save people from natural disasters that were occurring as a result of their attempt to shift it into another dimension. Shortly after meeting for tea with his other incarnations to celebrate in the Under Gallery, (PROSE: The Day of the Doctor) the Sixth Doctor lost all memory of the events due to the timelines not being synchronised. (TV: The Day of the Doctor)

The Doctor tried to save a young girl from a book printed on psychic paper. However, his attempts at communication only made the girl feel uncomfortable about him until the book claimed her. (PROSE: Academic Notes)

As part of a plan by the to take the Doctor's place in history, (AUDIO:  The Secret History) the Sixth Doctor swapped places with the Second Doctor just as the Second Doctor had discovered a long-lost Cyber-Tomb, prompting the Sixth Doctor to remain and investigate when the Second Doctor would have left. Although his actions nearly gave the Cybermen the chance to alter the outcome of the last Cyber-War, prompting the Sixth Doctor to contemplate calling the Time Lords for help despite the risks, Zoe Heriot was able to help him realise what the Second Doctor would have done and take action to stop the Cybermen, simply trapping them in a loop while he returned to his own place in time. (AUDIO: Last of the Cybermen)

While fighting the Sontarans, the Doctor was attacked by time flies. (COMIC: A Stitch in Time)

Upon coming back to his Baker Street residence in the 1890s, the Doctor found a letter from Jago and Litefoot, asking for his help against a mysterious sensation of tiredness they had been having for some time. From that description, the Doctor suspected the involvement of the Master in his decayed form; he then went back in time to when they started experiencing such feeling and disguised himself as Mr. Nocturne, assistant to Madame Sosostris, a hypnotist working at Jago's theatre. He was present when Jago and Litefoot accused her of hypnotising Inspector Quick and commanding him to mount the mirrors which were taking away their life force. He persuaded them to have Sosostris hypnotise Quick and remember everything the Master had ordered him to do. While Jago, Litefoot and Sosostris went to confront the Master, the Doctor together with Quick and Ellie Higson went to dismantle the mirrors and switched them with their counterparts in the Master's laboratory; he then tricked the Master, with Quick's help, by using the device to kill Jago and Litefoot by absorbing all their life force. Due to the mirrors being switched, the Master instead gave them back the energy that had been taken from them, and was left weak and frail, albeit with enough strength to retrieve his TARDIS and run away. (AUDIO: Masterpiece)

The Doctor wanted Harry Houdini's help and took him from a show in 1917. They followed a clue found in the pocket of Reynolds, who was apparently was working for Helga Schmidt and the German Army.

After stopping Oberst Brandt's plans, the Doctor helped Peri return to her people. (AUDIO: Harry Houdini's War)

Early adventures with Mrs. Constance Clarke
The Doctor met Constance Clarke, one of the WRENs stationed at Bletchley Park and the pair worked together to defeat the extraterrestrial Waveform and a triple agent named Robbie Flint. (AUDIO: Criss-Cross) She joined him on his travels. Constance found an email in the TARDIS inbox for Second Rani's parole hearing. The Doctor then followed the Rani to Miasimia Goria where she took Constance and discovered what had happened there. (AUDIO: Planet of the Rani) They later travelled to Arizona in 2029 after colliding with something in the vortex. He discovered a Viking burial mound there. They then found something strange in the snow and realised that the shield was a transmat relay. He combatted the Talessh there but wanted to release them from the transmat station and return them to his people. (AUDIO: Shield of the Jötunn)

The Doctor and Constance investigated a dimensional nexus made out of a train station with ever-increasing platforms and people, appearing multiple times, who were dead. A trainspotter, Keith Potter, revealed himself as an avatar of the Master and was killed by Tim Hope, who without the Doctor realising, was the Valeyard in disguise. (AUDIO: The End of the Line)

Responding to a distress call, the Doctor and Constance landed on Triketha. He found the way the Toxarians collected data about them, and could hear them telepathically. He learnt that the Toxarians were not native to this planet and went to find the spaceship that took them their. He discovered that the ship contained a set of rare and endangered species. He defrosted Tarlos from his cryochamber, and learnt more about the venom. He realised that Tarlos was a former travelling companion during his second incarnation. He managed to stop the insects and rescued Constance, Tarlos and Edwin from the explosion. He vowed to try and regain his memories of Tarlos. (AUDIO:Colony of Fear)

Landing on a primitive planet, the Doctor and Constance were forced to join forces with agents of the Galactic Census to investigate an anomalous signal from the planet. Tracking the signal to the monastery of the Order of the Black Petal, the Doctor and Constance learned that the Order had been infiltrated by a team of crashed Daleks, who had used their latent psychokinetic abilities to infiltrate the Order's psychic network. Working with members of the Order, the Doctor was able to destroy the Daleks and end their threat. (AUDIO: Order of the Daleks)

The Doctor and Constance arrived on the planet Teymah in the middle of an expedition conducted by Lyam Yce to discover why the native species became extinct. The expedition released an ancient alien intelligence called the Ninexie, which the Doctor and Constance were able to stop by trapping it in the TARDIS. (AUDIO: Absolute Power)

Rejoined by Flip
On returning to Bletchley, the Doctor and Constance discovered a telegram informing Constance of the disappearance of her husband, Henry Clarke. Wanting to do right by Constance, the Doctor secretly investigated the assignment Henry was working when he disappeared, Operation: Quicksilver, and discovered a war happening between two races, the Vilal and the Zerith, in Vienna. Evoking his Time Lord authority with a giant psychic projection of himself, he ended their war on Earth. Afterwards, he left in the TARDIS with Constance to return Flip, who had been snatched away from her wedding in 2012 by the Zerith as leverage against the Doctor, home. (AUDIO: Quicksilver)

The Doctor took Flip and Constance to Bath, England in 1756 where he planned to take them to the famous baths. He helped rescue Theodosia Middlemint's dog. He took Theodosia to a coffee house for hot chocolate and learnt about her brother's, business. He went after Titus Craven when he kidnapped Flip and followed them to Bristol. He helped the slaves escape and encouraged them to blow up the brass works. He piloted the TARDIS to rescue Flip and Clara from the sinking ship. (AUDIO: The Behemoth)

The TARDIS landed on Formicia, where Flip planned to celebrate Constance's birthday. The population saw the Doctor as something odd and a coward as he was old. When the system realised his age he was sent the End, where he learnt from Roman that the elderly was used as an army. At an audience against the Middleman, he protested against the war and the Middleman threatened Flip with execution. Janaiya told him about how the Kronvos invasion caused the change of the society so that the Elderly became the army not the youth. The Doctor found out that there was no Kronvos army. (AUDIO: The Middle)

The Doctor brought Constance and Flip to Abbey Marston, in 1980, after tracing some strange temporal anomalies there. He met Percy Till, who had met him before, though the Doctor had not experienced that meeting yet. The Doctor became intrigued when Joanna Nash heard her dead sister Susannah Nash who later came back from the dead. He decided to go back to 1940 to find out why the army was interested in this place. He learnt from Hardwick that they resurrected pilots that went missing in action. He learnt that Percy was one of the people who had died. He discovered the Shams and learnt how they were involved in bringing the people back to life. He discovered this was part of the Static's plan to invade. He saw Constance die but brought her back to life as part of the defeat of the Static. (AUDIO: Static)

The Doctor made multiple attempts to get to Bletchley Park, but Constance asked to stay a bit more. After some trouble with the TARDIS, he made an emergency landing on Cygia-Rema meeting the Vultriss. Being taken to the main city, he found out from Skye that there was going be an alien ambassador coming to the planet and learnt that it was a set of Ice Warriors. He was accused of being a spy. He learnt of ancient Time Lord technology on the planet which was there to stabilise a temporal rip. He learnt from the Martian ambassador Exazril what Vextyr was planning with the crystals. After stopping Vextyr, he stayed on the planet for three months to help rebuild. (AUDIO: Cry of the Vultriss)

Landing in France in 1944, he wanted to leave immediately to protect Constance as it was her immediate future. He learnt about a strange forest fire that happened near the village. When Flip tried to stop the lynching of Clementine, he had to intervene to stop it happening to her. He discovered a strange fire that was attacking the German soldiers, which he thought was strange. He later rescued Flip and Clementine from a burning flat. After the Furio was sent after the Doctor and his friends, he sent it to Berlin naively. He chased after it in a plane and asked Lucien to persuade it that the war is over, suggesting it to go to Skaro. (AUDIO: Scorched Earth)

The Doctor encountered Calypso Jonze who asked him to help find the Somnifax, and they tracked it to 1937 America. The Doctor wanted to destroy the creature but Calypso wanted to capture it for its bounty. The Doctor went into H. P. Lovecraft's mind to extract the Sominfax with Flip. He made his way through the Lovecraftian world and discovered that the Somnifax wanted to summon Cthulhu. He used the logic of the Lovecraft Mythos to defeat the Somnifax. The Doctor then lectured Lovecraft about his racist views after he suggested that he and the Doctor were equals. (AUDIO: The Lovecraft Invasion)

After taking Flip to a hospital to recover, the Doctor and Constance explored the surrounding city when it came under attack from the Freebooters. He wanted to end them to protect Flip, and contacted Calypso Jonze for help. They took the Doctor and Constance to the Freebooter's section of space. He was contacted by Vakrass but couldn't remember fully the last time he met him. He demanded to El Zeddo to stop their attacks on Titan. His negotiations failed. He found a Time Lord data crystal in El Zeddo's memory and reset him to factory settings. He then programmed Jonze's ship to one of the Freebooter's treasure hauls to repay them. The Doctor and Constance were then abducted by Vakrass before they could return to Flip. He took him and Constance to his base of operations near the fabled location of the lost moon of Botoya. The Doctor encountered his Fifth and Eighth incarnations. On Vakrass’ request, the Doctors travelled to the lost moon of Gallifrey, via a portal formed by the medallions each Doctor had found, to find Gostak. The Doctors learned that the moon was a complex temporal manipulation device that Gostak intended to use to undo the last few thousand millennia to re-establish the Time Lords as a vast empire. The Doctors refused to help his plans, with Gostak's efforts to force their aid being cut short as the Doctors turned the moon's power against itself, aided by the arrival of the Seventh Doctor with a control rod for the moon's system. He then planned to go back and collect Flip and go on a new adventure. (AUDIO: The End of the Beginning)

Temporary companions
The Doctor was contacted by Bernice Summerfield, and told that the Sirens of Time had hijacked the first Gallifreyan experiment of time travel, turning it into a time paradox that was splitting the universe apart. While the experiment had already been stopped, the Time Lords were in danger of not discovering time travel. Along with his third, fourth, fifth, seventh and eighth incarnations, the Sixth Doctor was brought to the planet Henlen to serve as one of the six pilots needed to handle the TARDIS prototype, while his first, second and tenth incarnations stayed behind to deal with the possible backlash. The experiment was successful, restoring the correct timeline and the Sixth Doctor was taken back to his own time by Benny. (AUDIO: Collision Course)

Arriving in the 1970s, the Doctor encountered his ballroom dancing instructor Becky as a teenager. He taught her the steps she would teach him in the future, but realised too late that his efforts to reform Becky's future husband had been poorly planned. (PROSE: Teach Yourself Ballroom Dancing)

The Doctor purchased 51% of Golden Futures and became the Managing Director. River Song became an office temp placement and she discovered that the real shareholders plan was o destroy Earth and replace with Elysium and sell it as real estate. River used amnesia lipstick on the Doctor so that he would have no memory of their encounter. (AUDIO: World Enough and Time)

The Doctor rescued Mathew Sharpe from his ship in 2715 and took him on several adventures, such as meeting the Quarks. On his way to take him home, he received a distress signal from a ship and explored it with Mathew. He encountered Esther Brak who stunned him and the later the Geist Willoway. He worked out this ship was the Nomad because of the artron energy crystals. He opened the time bubble and discovered Juniper Hartigan. He learnt that Mathew was a Myriad and had manipulated him to get Hartigan. (AUDIO: The Lure of the Nomad)

The Doctor landed in the Thames tunnel built by Marc Brunel and encountered Isambard Kingdom Brunel in it. He learnt from the workmen about a ghost in the tunnel and he offered to help to dispel this rumour. He discovered something strange living in the tunnel. He learnt from Tan about a strange city under the Thames and about the tributes. He was attacked by Alayna. Rispa showed him about the windows into London and how they made their tributes. He discovered that the Luceat was from a parallel universe and became connected when a transmat experiment went wrong. (AUDIO: Iron Bright)

UNIT called the Doctor back to London in 1992. Lewis Price told him about the unnatural drought which was only affecting Britain. He traced a signal to a ship on the other side of Mars and discovered that the Veridians were there, and went back to the source of the signal. Shortly after arriving, he discovered that the Cybermen were active on Earth. He investigated the Cybership learning that it was under a UNIT facility. He later theorised that there must be a Cyber Agent in UNIT. After discovering that cyber technology was in the UNIT satellites, he traced their control signals to a cyber fleet under the Atlantic Ocean. He realised that Daniel Hopkins was a cyber agent as he knew of Veridian biology. He was taken to cyber control. He tampered with controls to the satellites and destroy the cyber fleet. He recommended that Hopkins be placed in confinement. (AUDIO: Hour of the Cybermen)

The Doctor once discovered a dead body with a frozen face in Iceland and encountered Yrsa Kristjansdottir, who was investigating it. He helped in her investigation and discovered an alien was working in Iceland and keeping hunting trophies. The Doctor followed the Hunter to another planet, Valin, were he encountered the Marficks. He learnt from them about the Hellion. He stopped the Hunter by melting the ice below him. The Doctor offered to take Yrsa with him on his travels. (AUDIO: The Hunting Ground)

History takes its course
After foiling a plot by the Master and a Usurian to take over the stock market, (PROSE: Millennial Rites) the Doctor finally became acquainted with Mel on a beach in Brighton in 1989, before they were forced to defeat the Nestene Consciousness together with the Brigadier. After the situation was resolved, Mel elected to travel with the Doctor. (PROSE: Business Unusual)

With Mel by his side, (PROSE: Millennial Rites) the Doctor was involved in a battle with the Terrible Zodin that involved multiple incarnations of himself, though he lost his memory of the adventure after Zodin used "mind rubbers" on him and his other incarnations. (PROSE: Cold Fusion)

While playing a game of Monopoly, the Doctor's TARDIS answered a distress signal from the Vulgar End of Time, a point in the far future where everything had already been discovered. Arriving on the planet Generios 1, the Doctor and Mel encountered a scam artist named Banto Zame, who, together with his assistant, Sally-Anne Stubbins, were claiming to be the Doctor and his companion and were creating fake dangers to con the people into paying them to help. However, a real threat appeared in the skies and offered to let the people live if they handed over the three greatest treasures of the Generios system. The Doctor and Mel teamed up with their pretenders and underwent a quest to find the treasures. Convincing Sally of her own worth, the Doctor managed to defeat the Cylinder, tricking it into taking Zame instead of himself. (AUDIO: The One Doctor)

Briefly separated from Mel when the spaceship they were on was attacked, the Doctor was "rescued" by the Daleks, while Mel ended up working as part of a scientific research team led by a disguised Davros. Learning that Davros was modifying salvaged Mechonoids into the new Juggernauts, the Doctor and Mel were shaken when they learned that the Juggernauts used human tissue in their construction. Mel utilised a back door she had installed in their programming to turn them against Davros and the colony was destroyed in the resulting battle while Mel's new friends escaped. (AUDIO: The Juggernauts)

While visiting Mel's uncle, John Hallam, in 2003, Mel was transported to 1782 where she awoke with amnesia. The Doctor and Hallam travelled there and learned that she had been taken in by a local aristocrat. Mel had mistakenly been drugged by one of the village doctors, not knowing it was partly because of the medicine that her memory stayed distorted. The Doctor realised that Mel had become one of her own ancestors and struggled with trying to maintain the timeline, but found a way around it in order to save Mel. (AUDIO: Catch-1782)

Having heard of her, Mel requested that they visit Evelyn Smythe. The Doctor worked with Evelyn's stepdaughter, Dr Sofia Rossiter, to rescue Evelyn and Mel who were kidnapped to become political prisoners. When Evelyn was injected with Killoran DNA, the Doctor saved her and they made peace at the renewing of Evelyn and Rossiter's vows. (AUDIO: Thicker Than Water)

In 1957, the Doctor and Mel investigated UFO sightings in the proximity of Hammerston, Louisiana and became involved in the production of the film Swamp of Horrors after attacking an actor in a rubber alien suit whom they mistook for a genuine alien. The Doctor and Mel were assumed to be uncredited actors playing fictional characters by film critics. (PROSE: Swamp of Horrors (1957) - Viewing Notes)

After arriving on a hospital spaceship crewed by the Sisters of Plenitude, the Doctor and Mel explained a miscommunication between the children and the Catkind that had led to the children mistakenly believing the Catkind were going to eat them, when the cat nuns were actually synthesising an antihistamine to combat allergies to cats, and held a Christmas celebration with them. (PROSE: Fairy Tale of New New York)

Hearing a distress call from a strange asteroid, the Doctor and Mel discovered two stranded humans, Maria and Eliza Applewhite, who lived in fear of the Wishing Beast. Realising what it was, the Doctor stopped his power. (AUDIO: The Wishing Beast) Later landing in Salford in 1965, the Doctor was intrigued by the local hairdresser Mr Coiffure who could make his clients younger. The Doctor realised this was an earlier version of the Wishing Beast. (AUDIO: The Vanity Box)

The Doctor and Mel then travelled to Tantane Spaceport, where the Doctor discovered two warring tribes of humans who had been stranded there by a group Wailers. (AUDIO: Spaceport Fear)

Mel convinced the Doctor to install an answering machine in the TARDIS; as he did so, he also took the chance of admonishing River Song to stop pestering about reaching her to the Apocalypse Vault. (AUDIO: Expiry Dating)

Traveling with Peri and Mel
According to an account where the Doctor travelled with both Peri and Mel, they forced him to skip as a form of exercise, though his skipping got so extreme that his clothes were flung off. (PROSE: Skipping Song)

The final adventures
Arriving on Earth in 1999, the Doctor visited his old friend, Dame Anne Travers, while Mel became unwittingly caught up in Ashley Chapel's attempt to summon the powerful entity Saraquazel to Earth, a resulting disruption of reality as Chapel tried to summon Saraquazel and Anne, misinterpreting Chapel's plans as an attempt to summon the Great Intelligence, tried to banish the Intelligence, turning Chapel, Anne and Mel into the three rulers of three great kingdoms, each adhering to a different law of physics. The Doctor was nearly mutated into the Valeyard by the resulting disruption of reality, but he was able to resist the influence long enough to undo the damage and restore Mel and the others to normal. (PROSE: Millennial Rites)

The Doctor was called to a spaceship to be used as a scapegoat to drive out hijackers. However, this plan turned sour when a genetically engineered species known as the Vervoids emerged from their pods in storage and killed many of the passengers, simultaneously causing several others to mutate into new members of their own kind. With the Vervoids attempting to convert all of humanity, the Doctor was forced to destroy them by fast-forwarding their lifecycle, as he knew that just one Vervoid making it to Earth would allow this to happen. (TV: Terror of the Vervoids)

The Doctor and Mel took a trip to Oxyveguramosa, where Mel was taken by to give testament at the Doctor's trial, (PROSE: The Ultimate Foe) and later returned by the past Doctor after a brief stop at Pease Pottage. (AUDIO: The Wrong Doctors)

After the Doctor's attempt to stop a minor conflict on the planet Maradnias accidentally escalated that conflict into a nuclear apocalypse, Mel contemplated leaving the TARDIS, but these plans were interrupted when the Doctor detected a trace of temporal technology on Earth. Tracking the source, the Doctor discovered Stuart Hyde had helped his new protégé, Paul Kairos, adapt TOMTIT's technology into the TITAN Array that would allow humanity to perceive the higher dimensions, just as appeared to try and adapt TITAN for his own purposes. The Master's actions resulted in the creation of the Quantum Archangel, an entity composed on the human consciousness of Anjeliqua Whitefriar, the power of the Lux Aeterna, and the quantum processing power of the Mad Mind of Bophemeral, who sought to make reality "better" for all despite the risks of attracting the attention of the Chronovores.

Learning that this whole plan had been manipulated by Kronos as his attempt for revenge on the Chronovores for condemning him due to being a Chronovore/Eternal hybrid, the Doctor took on the dregs of power left from Lux Aeterna to delay the Quantum Archangel until Kronos could destroy the Mad Mind, prompting Anjeliqua to forsake her power. As thanks for his help in this crisis, the Eternals and the Chronovores erased both the Doctor's trip to Maradnias and the conflict he had originally travelled there to stop. (PROSE: The Quantum Archangel)

The Doctor and Mel arrived on Earth in the year 1993, where they encountered Evelyn. The Doctor chastised Evelyn for using her knowledge of the future to make money. The Doctor, Mel, and Evelyn then encountered Cellian and Ciara, who had rebelled against their Nestene control, and stopped a plan by two Cylox criminals to take over Earth. After the two Cyloxes were killed by their jailer, and Cellian and Ciara were killed in battle, Evelyn decided to join the Doctor and Mel on their travels. (PROSE: Instruments of Darkness)

Deciding to take Mel to the Great Tower of Kalsos, the Doctor arrived around 80 years too late, as it was to be destroyed to mark the end of the war against The Eminence. After being taken to Ridius IV he encountered and learnt from Helgert Teveler about the problems with the seeds because of the war and devised a plan to get uncontaminated seeds from the seed bank on Earth. The Eminence which had infected the Doctor in his fourth incarnation planned to contaminate these seeds to defeat the humans by starvation, but the Doctor tricked them. (AUDIO: The Seeds of War)

Preparing for the end
Shortly after being given a glimpse of his future, (PROSE: Curtain Call) the Doctor assisted a group of revolutionaries fight against the repressive regime of their planet, but was captured and taken to House Osmo, a palatial structure that contained books that predicted the events of someone's life. Reading his own book, the Doctor learned he was nearing his death. (PROSE: The Book of My Life)

The Doctor decided to prepare for his demise by returning to the dawn of time and carving "The Doctor was here" on the first inhabitable planet, and then travelled to Germany to play guitar with the Beatles. He observed the birth of Ludwig van Beethoven and gave his mother enough money to ensure that she would be able to keep the child her husband didn't want. He then visited his old mentor at the time of his death, to bid him thanks and farewell. (PROSE: Gone Too Soon)

Manipulations
According to one account, just after almost becoming the Valeyard and nearly killing Mel on 1 January 2000, the Doctor was influenced by his next incarnation into killing himself. The Seventh Doctor did this out of fear of becoming the Valeyard (PROSE: Head Games) and because he felt he needed to be "born". According to Death's version of events, the Doctor joyfully piloted his TARDIS towards 's tractor beam, (PROSE: Love and War) though Mel witnessed him attempting to activate the HADS. (PROSE: Time and the Rani) Another account explained that it was in fact Fenric who manipulated the events of the Doctor's sixth regeneration. (PROSE: The Runes of Fenric)

The Rani's attack buffeted the TARDIS out of flight, (TV: Time and the Rani) and caused the Doctor's head to collide with the TARDIS control console, (PROSE: Time and the Rani) forcing him to regenerate (PROSE: Head Games) as the TARDIS was pulled on to Lakertya. (TV: Time and the Rani)

Fighting the Lamprey
According to a second account, the Doctor's adventures eventually led him to the Library of Carsus, after encountering his future self in the TARDIS, where he worked with an old Time Lord friend, Professor Rummas, and many alternative versions of himself from different universes to stop the Lamprey, a pan-dimensional being, from destroying creation with the power of the Spiral Chamber, a powerful Time Lord artefact that acted as a portal into the nexus of the Time Vortex. However, the Doctor was forced to sacrifice much of his chronal energy to trap the Lamprey inside the Chamber. The toll of the Lamprey's imprisonment drained the vitality out of the Doctor as time-sensitive chronon particles, which helped sustain his life force, were stripped away from his body.

Dying, the Doctor materialised the TARDIS in deep space to take one last look at the universe. Satisfied with the life he had led, the Doctor told Mel not to feel cheated by his demise, before he drifted into a half-conscious haze and slumped over. (PROSE: Spiral Scratch) However, the TARDIS became under attack from the Rani and was lured into a tractor beam and forced to land on the planet Lakertya. (TV: Time and the Rani) The attack on his TARDIS knocked him into the TARDIS console, where he struck his head. As the Doctor was already dying from chronal starvation, (PROSE: Spiral Scratch) the head injury became a killing blow. (PROSE: Head Games; AUDIO: Zagreus)

Attack from Lakertya
According to another account, the Doctor tried to travel to the Lakertyan System, but discovered there was deadly radiation nearby. Before he could divert the TARDIS away, he received a signal from a future version of his current incarnation and froze up for a moment. For reasons he couldn't explain, the Doctor was now compelled to visit Lakertya despite the danger, and continued his present course. His TARDIS was soon caught in a barrage of laser fire made of focused radiation beams. As the ship was struck and jolted repeatedly, the radiation caused Mel to lose consciousness, but the Doctor feared that he would fare far worse.

Unable to tell Mel before she passed out, the Doctor revealed that the radiation was fatal to Time Lords, and fell over onto the floor. Weakened by the attack, the Doctor made peace with the idea his time had come, fearing that he might fail to regenerate. However, as he lay dying, a figure appeared to him and told him it was "far from being all over." The Doctor wondered who it was as regenerative energy began to flow out of him, (AUDIO: The Brink of Death) and the TARDIS was snared by a tractor beam and forced to land on Lakertya. (TV: Time and the Rani)

Falling off an exercise bike
Another account suggested that the Sixth Doctor fell off his exercise bike during flight and had to regenerate from the fall, though the Twelfth Doctor admitted he could not fully remember the exact circumstances. (PROSE: The Complete History of the Doctor)

Regeneration
As the Doctor lay unconscious on the floor of his TARDIS after the TARDIS landed on Lakertya, and her Tetrap servant, Urak, invaded the TARDIS, and Urak was ordered to leave Mel behind and take the Doctor to the Rani's laboratory. As Urak rolled the Doctor onto his back in preparation to take him away, the final stages of his regeneration commenced, and he transformed into his seventh incarnation. (TV: Time and the Rani)

Post-mortem
Due to his innate hubris and pre-inclination towards violence, the Seventh Doctor feared that his predecessor was a darker incarnation than his other selves, a fact which caused his memory of the Sixth Doctor to become increasingly twisted, to the point that the memories of the other five Doctors kept the sixth incarnation imprisoned deep in the Doctor's mind for fear of him becoming the Valeyard. (PROSE: Head Games) However, after he was shot by an arrow and woke up in his own grave, the Seventh Doctor accepted that nobody deserved to be locked up forever, recognising the need to forgive himself and remove the guilt that would have corrupted the Sixth Doctor's memory into becoming the Valeyard. (PROSE: The Room With No Doors)

When the Eighth Doctor and the TARDIS were contaminated by anti-time, the TARDIS created various historical projections of past encounters with the mysterious "Divergence" to consider its options, with the TARDIS's "good" side using images of the Doctor's past selves and companions to represent key players in these projections. The image of the Sixth Doctor was used for the vampire Lord Tepesh, granting the Tepesh projection some of the Doctor's knowledge and experience of events that the original Tepesh could not have known. Although Rassilon "killed" the projection, when Charley stabbed the Eighth Doctor he was greeted by his immediate three predecessors in his mind, the previous Doctors working with the Eighth Doctor to allow Zagreus to take control and heal their injury. (AUDIO: Zagreus)

When the Tenth Doctor was confronted by Es'Cartrss within the TARDIS' Matrix, he summoned the Sixth Doctor, among his other past incarnations, to use their united memories and willpower to take back control of the Matrix. (COMIC: The Forgotten)

During many failed attempts to duplicate the Tenth Doctor, defective copies of all his past incarnations, including the Sixth Doctor, were created instead. (COMIC: Breakfast at Tyranny's)

After the Eleventh Doctor was accused of committing deadly crimes against the Overcast, he brooded in the TARDIS for two days, imagining all his previous numbered incarnations, including the Sixth Doctor, interrogating him over the crimes. When he offered the rationale that he always left things better than he found them, they all turned and left him in disgust and disgrace. (COMIC: Pull to Open)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Sixth Doctor, appeared inside it to defend themselves as well. When auditor Sondrah accused the Doctor of being a meddler, the Sixth Doctor protested the description, denying that he had ever meddled in the ways of the Earth, only for the Seventh Doctor to admit to having meddled "just a little". 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 Clara Oswald entered the Doctor's time stream, she saw the sixth incarnation among the Doctors that ran past her, with the Eleventh Doctor claiming them to be his "ghosts". (TV: The Name of the Doctor)

After saving Gallifrey from the Moment at the conclusion of the Last Great Time War, the Eleventh Doctor dreamed of himself standing with all his past incarnation, including the Sixth Doctor, as he thought about his search for Gallifrey. (TV: The Day of the Doctor)

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

Undated events

 * The Sixth Doctor attended the funeral of Alistair Gordon Lethbridge-Stewart, (PROSE: The Gift) where he comforted Jo Jones during the burial. (PROSE: Shroud of Sorrow)
 * River Song met the Sixth Doctor, but did not care for him, comparing him to "a clown put through a woodchipper". She had his memory wiped with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)
 * On a Thursday in the summer of 1966, the Sixth Doctor visited Andy Warhol to have his face added to a portrait of eleven incarnations of the Doctor. (PROSE: The War of Art; COMIC: The Girl Who Loved Doctor Who)
 * The Sixth Doctor once went on a pub crawl across London with Clive Dunn. (PROSE: Twice Upon a Time)

Alternate timelines
In an alternate timeline, the Doctor became President of the Time Lords, and, in his sixth incarnation, led a battle in the war with the Daleks. With the assistance of the Master, the Daleks began winning the war. Rather than letting them take control of the universe, the Doctor activated the Armageddon Sapphire, destroying the entire universe. (PROSE: The Quantum Archangel)

In one alternate timeline, the Doctor had his throat slit by Shockeye. In another, he saved Oscar Botcherby's life by arriving thirty seconds before Oscar was killed by Shockeye, instead of thirty seconds afterwards. (PROSE: So Vile a Sin)

In a negated timeline, the Doctor and Peri were almost forced to land at the Big Bang due to mysterious coordinates being sent to the TARDIS. Escaping the explosion, the Doctor and Peri arrived at a Vess warehouse, and learnt the full magnitude of the situation with the Seventh Doctor and Ace. Contacted by CIA agent Straxus as Peri vanished, the Sixth Doctor discovered that had blackmailed the CIA into giving him a conceptual bomb, which he then set off inside the mind of Bob Dovie when he entered the Fifth Doctor's TARDIS; Davie's refusal to accept its existence caused the TARDIS to explode in its own timeline until it never existed. The Sixth Doctor then expanded the dimensional stabiliser on Straxus' TARDIS and was able to summon his other seven incarnations to help stop the Master. The Fifth Doctor went to 1962, and showed Dovie the TARDIS then, so that he would not be dumbfounded by the TARDIS's interior and therefore preventing the bomb's detonation. The Sixth Doctor then joined his other seven incarnations in preparing to time ram the Master's TARDIS. However, rather than kill the Master, the First Doctor instead turned off the automatic distress actions, which had brought all of the Doctors to the pocket dimension and triggered the TARDIS' destruction, making it so none of that had happened. (AUDIO: The Light at the End)

When the Eighth Doctor arrived at the Sixth Doctor's trial, the Valeyard was able to force an alternate timeline where a guilty verdict was delivered against the Sixth Doctor on genocide charges. Rescued from execution by his eighth incarnation, the alternate Sixth Doctor created by the Valeyard's actions accompanied him to Gallifrey. The two set up a Presidential Inquiry into their current trial. The Sixth Doctor managing to deliver his own testimony before the timeline that created him ceased, leaving the Eighth Doctor to continue the investigation into the trial, to the point of bringing in Borusa to stabilise the situation. (PROSE: The Eight Doctors)

When the Cybermen allied with Rassilon to take over history, (COMIC: Supremacy of the Cybermen) the Doctor found that the Cybermen had taken over the Matrix during his battle with the Valeyard, (COMIC: Prologue: the Sixth Doctor) and he and Mel were captured by the Cybermen. This timeline was eventually unwritten by Rassilon and the Twelfth Doctor. (COMIC: Supremacy of the Cybermen)

In a timeline where a Dalek invasion of Earth in 1903 was thwarted by the Doctor and Evelyn, the British Government trapped the Doctor in the Tower of London along with the two surviving Daleks to keep him as a symbol of their victory, cutting off his legs in order to keep him trapped. Driven insane over the years, the Doctor sometimes spoke to hallucinations of Evelyn after she died of old age, not even fully aware when a younger Evelyn came to see him in the Tower. He was eventually exterminated by the last surviving Dalek when it came to ask him for orders as it didn't know what else to do with itself. (AUDIO: Jubilee)

During the fight with the Lamprey, several alternate Doctors were travelling with different companions, such as Evelyn Smythe, a half cyber-converted Evelyn Smythe, Frobisher, a human/Silurian hybrid Melanie Baal, and Peri Brown. One Doctor, hailing from a timeline where Rome never fell, lost his left eye in the events that led to the death of his companion Perpugilliam of the Brown, keeping the injury as a reminder of his shame. (PROSE: Spiral Scratch)

Adventures that were wiped from history
Before meeting Frobisher, the Doctor travelled with William. (PROSE: Gone Fishing, Walkin' City Blues, Certificate of Destruction, The Earwig Archipelago) These events were undone by the Eighth Doctor in order to stop Flora Millrace embarking on her murder spree. (PROSE: DS Al Fine)

Facing the final curtain
The Doctor tried to travel to the Lakertyan System, but discovered there was deadly radiation nearby and quickly fled, attempting to take Mel to Zastros 8, but instead ending up on Zastros 9, a totalitarian state, and becoming caught up in another situation they only narrowly escaped from when the planet's denizens set chase after them. Back on board his TARDIS, the Doctor found the underside of the TARDIS console smoking. As he went to examine the problem, his consciousness was suddenly transported to the Matrix, and the Valeyard took over his body. Inside the Matrix, the Doctor met a Gallifreyan technician named Genesta, who warned him he was dying. He eventually discovered her to be the Valeyard in disguise.

Throughout their climactic encounter, the Valeyard taunted the Doctor, informing him that he had effectively used creatures called Nathemus to replace the entire Time Lord civilisation with his consciousness and implanted them inside the symbiotic nuclei of the TARDIS. Since the Nathemus fed off telepathic energy, they gained access to its telepathic link, and by extension, the Doctor's mind when he interacted with his ship symbiotically, which let them feed until they were able to gain access to the Matrix, giving the Valeyard a means to take it over and alter history. Because of this, both the Doctor and his TARDIS were now empowering the Nathemus and subject to their influence.

Having been completely defeated in the present, the Doctor realised the only way to break the parasitic hold the Nathemus had on him would be to put a halt to the Valeyard's master scheme in the past. He sent himself a psychic signal via a telepathic impulse from his own TARDIS to go to Lakertya regardless of the danger and experience the deadly radiation, believing he would die if he did so. Suddenly put in a threatened position, the Valeyard tried to convince the Doctor not to go with his plan, but the Doctor carried on, readying himself for the end by reminiscing of all the companions he had during his lifetime. The Valeyard challenged him with the fact that if he didn't die, but regenerated, the Nathemus would still survive. However, the Doctor knew through the process of regeneration, all the cells in his body would be replaced anew, including those of his mind. The Nathemus were linked to the unique mind he had in his present state, but with his mind reshaped, the Nathemus would no longer have any connection with him to feed on it or subsequently manipulate the TARDIS, starving them to death.

After sending his past self the message, therefore undoing all the damage the Valeyard managed to inflict on history, the Valeyard found himself reduced to a powerless form in the Matrix, cut off from the universe and left to shrivel up and die, though it also meant the end for the Sixth Doctor as well. His consciousness began to wane in the wake of time being rewritten, and he sensed the change occurring. (AUDIO: The Brink of Death)

Personality
The Sixth Doctor could be unpredictable, consistently self-absorbed, stubborn, argumentative, moody, melodramatic and arrogant, believing himself greatly superior to anyone he encountered. (TV: The Twin Dilemma, Attack of the Cybermen, Vengeance on Varos, The Two Doctors, Timelash, The Mysterious Planet) However, he was critical of himself in some situations, (TV: The Twin Dilemma, Attack of the Cybermen, Revelation of the Daleks) and, beneath his thunderous exterior, he was a passionate and emphatic individual. (AUDIO: Arrangements for War) Despite his hubris approach, the Doctor knew when to be serious, such as when he rushed to help Gustave Lytton after exiting his TARDIS in a comedic manner. (TV: Attack of the Cybermen)

The Doctor described himself as "pragmatic", and considered compassion and a "capacity for self-sacrifice" as "some of [his] defining traits". (AUDIO: The Sirens of Time) He also believed himself to be blessed with both "tact and finesse", (TV: Terror of the Vervoids) and believed he could subdue opponents with his charm. (TV: Attack of the Cybermen) He would often browbeat others into submission with his grammarian use of language, with Banto Zame complaining that "talking [to him was] like arguing with a thesaurus", (AUDIO: The One Doctor) and Sabalom Glitz saying the Doctor could "talk an ayatollah into opening an off-licence". (PROSE: Mission: Impractical)

When Peri was distressed over the idea that Ravolox was a devastated Earth, the Doctor tried to comfort her, even showing empathy for her plight, despite initially telling her not to get emotional. (TV: The Mysterious Planet) He was devastated when presented with the news of Peri's demise on Thoros Beta, and was enraged that the Time Lords had engineered her execution, threatening he had every intention of discovering what they were up to. (TV: Mindwarp) When he discovered the Time Lords had relocated Earth and renamed it Ravolox to keep the secrets of the Matrix from being exposed, the Doctor announced his purpose was to stop evil and power mad conspirators. (TV: The Ultimate Foe)

After the events of his trial, the Doctor became more aggressive and irascible. (PROSE: Time of Your Life) However, this was used to cover up a deep feeling of depression which resided within. This depression was so deep and consuming, that he even got to the stage where he contemplated suicide. (PROSE: Killing Ground) Furthermore, the Doctor showed a lack of faith and even a dislike for his companion, Grant Markham, as a means of changing his future, demonstrating his lack of consideration for his companion, and even self-absorption for his own problems. (PROSE: Time of Your Life) However, his opinion of Grant changed after Grant proved that he wasn't as unlikeable as he initially believed. (PROSE: Killing Ground) After Grant left, the Doctor became a sombre individual, rather than being genuinely depressed. (AUDIO: The Wormery, Excelis Rising)

After being, in Melanie Bush's words, "tamed" by Evelyn Smythe, (AUDIO: Thicker Than Water) the Doctor mellowed out of his faults, keeping his egotistical outbursts to himself, and noting how annoying his previous habits were. (AUDIO: The Wrong Doctors) While travelling with Frobisher again, the Doctor became friendlier and more playful, sharing jokes with Frobisher even during serious situations. (AUDIO: The Holy Terror) By the time he travelled with Mel, the Doctor acted disciplined, aware that his actions had consequences, and was careful about what he did and where he went. (TV: Terror of the Vervoids)

Despite his often unstable demeanour, the Doctor was quick to act when the situation called for it, and very little, even his companions, could hope to get in his way. (TV: The Twin Dilemma, The Mysterious Planet, The Ultimate Foe) More than his other incarnations, the Sixth Doctor was a fatalist, more than once deciding he was doomed and resolving to accept his fate. (TV: Timelash, The Mysterious Planet, The Ultimate Foe)

His adventurous side still remained, but the Sixth Doctor was more selfish about it, especially when it came to decision making. He would often decide he knew what Peri wanted out of her travels and often told her where she wanted to go instead of asking her. (TV: Attack of the Cybermen, The Two Doctors, Timelash, The Mysterious Planet) He considered his inability to tell his destination to be "half the fun" of travelling. (AUDIO: The Ultimate Adventure)

A man of little fear, the Doctor would remain unfazed when in the line of fire, (TV: Attack of the Cybermen, The Mysterious Planet) or in the face of the unknown. (TV: Vengeance on Varos, The Ultimate Foe) Even when helpless or under threat, the Doctor would be unafraid to speak his mind. (TV: The Twin Dilemma, The Mark of the Rani, The Two Doctors, Revelation of the Daleks)

While he believed that the "purpose of life [was] too big to be knowable", the Doctor felt that "everything in life [had a] purpose" and that "every creature [played] its part". (TV: The Mysterious Planet) While he was willing to leave Hugo Lang for dead after Lang made an attempt to kill him, (TV: The Twin Dilemma) the Doctor was, for the most part, always willing to lend a helping hand wherever he could, (TV: Attack of the Cybermen, The Mark of the Rani, Revelation of the Daleks, The Mysterious Planet) and see that justice triumphed over the guilty. (TV: Mindwarp) When he blew out the candles on his 900th birthday cake his wishes were to "have better control of the TARDIS", "peace throughout the galaxy", and "more manageable hair". (AUDIO: The One Doctor)

Charley Pollard noted that the Sixth Doctor "had a way with cats", which he countered by stating that "cats had a way with [him]". (AUDIO: The Condemned) He wore several cat brooches on his left lapel, (TV: The Twin Dilemma) as well as cat cufflinks, (AUDIO: Trouble in Paradise) a tie printed with little cats on it, (PROSE: Blue Box) and carried a cat themed face mask on his person. (TV: The Mysterious Planet) He even owned a pair of silvery silk pyjamas covered in pictures of different species of cat, all of them wearing his Technicolor coat, (PROSE: Instruments of Darkness) and used cat photos to send encoded messages. (WC: Doctors Assemble!)

He also liked Pink Floyd's Piper at the Gates of Dawn, (PROSE: Business Unusual) Creature from the Black Lagoon, (AUDIO: Pier Pressure) and dinosaurs, (AUDIO: Excelis Rising) as well as hazelnuts, (AUDIO: The Condemned) and crispy Peking duck with prawn crackers. (AUDIO: Project: Twilight) His favourite sandwich flavour was peanut butter, lettuce and potato chip. (PROSE: Timeshare) "Serendipity" and "fortuitous" were among his favourite words, (AUDIO: The Hollows of Time) and Late-Victorian Britain was one of his favourite times and places. (PROSE: Wish You Were Here) He did not believe in luggage, (PROSE: The Death of Me) ghosts, (AUDIO: The Macros) or fate. (AUDIO: Urgent Calls) He took four sugars in his tea, (AUDIO: Project: Lazarus) and "just a dash of milk" in his coffee. (AUDIO: The Reaping)

The Doctor enjoyed how humanity was "seldom predictable". (AUDIO: The Ultimate Adventure)

He disliked hotels. (AUDIO: The One Doctor)

It was during his sixth incarnation that the Doctor began to see the logic in murder, (PROSE: Alien Bodies) and he was more willing to resort to a "modicum of force". (TV: The Mysterious Planet) While his physical attack on Peri could be attributed to post-regenerative trauma, (TV: The Twin Dilemma) he later stabbed a Cyberman scout to death with a Sonic lance, killed the Cyber-Controller at close range with a Cyber-gun, (TV: Attack of the Cybermen) seemed unperturbed after witnessing two men fall to their death in an acid bath, (TV: Vengeance on Varos) smothered Shockeye to death with a cyanide rag in self-defence, (TV: The Two Doctors) shot out a Renegade Dalek's eyestalk, (TV: Revelation of the Daleks) and killed Chintor with a double-barreled shotgun at close range. (PROSE: Retribution) He was also willing to allow a few deaths if it would protect the majority from harm, (WC: Real Time) such as destroying the Vervoids to stop them from dooming the human race, although he felt regretful with his actions. (TV: Terror of the Vervoids)

However, the Sixth Doctor also had a more emotional and caring side, determined to not let people die "if [there was] a chance of saving them". (TV: The Mysterious Planet) He was ashamed with himself when he learned he had attacked Peri in his post-regenerative trauma, (TV: The Twin Dilemma) worried what would become of Flast after he exposed her to warmer conditions, (TV: Attack of the Cybermen) commanded Peri to save herself instead of him when being carted away by 's miners, (TV: The Mark of the Rani) comforted a mutanted man as he died, was outraged by Davros's disregard for life, offered to find a way to avoid Orcini needing to sacrifice his life, and then agreed to honour his last request. (TV: Revelation of the Daleks) He claimed he would begin a "vegetarian diet" after almost transforming into an Androgum, (TV: The Two Doctors) but this claim was dubious. (PROSE: Instruments of Darkness, The Man Who Wouldn't Give Up)

He also mourned for Azmael, (TV: The Twin Dilemma) Gustave Lytton, (TV: Attack of the Cybermen) Luke Ward, (TV: The Mark of the Rani) Oscar Botcherby, (TV: The Two Doctors) Arthur Stengos, the DJ, (TV: Revelation of the Daleks) Dorf, (TV: Mindwarp) and Hallett. (TV: Terror of the Vervoids) He became grief-stricken when presented with evidence of Peri's untimely death, (TV: Mindwarp) describing his pain as "like dying [him]self," (AUDIO: Her Final Flight) and was most pleased when he discovered the evidence had been tampered with, and that Peri was alive. (TV: The Ultimate Foe)

The Doctor could be literal minded, checking Peri's back after she complained about her "heart being where [her] liver should be", and taking Lytton's "look around you" statement seriously. (TV: Attack of the Cybermen) When Lord Ravensworth asked the Doctor what he and Peri did in the TARDIS, the Doctor answered with, "argue, mainly". (TV: The Mark of the Rani) On Ravolox, the Doctor misunderstood Peri's reluctance to enter an abandoned building as her stating their inability to find an entrance. (TV: The Mysterious Planet)

He also seemed unable to see his own faults, but would hypocritically criticise those that showed them, particularly the Valeyard. (TV: The Ultimate Foe) He accused Peri of being an "egotistical young lady", (TV: The Caves of Androzani) and of being overweight. (TV: Revelation of the Daleks) He also rebuked Balazar for boasting about his knowledge. (TV: The Mysterious Planet) He did, however, admit he had misjudged Lytton following his death and their defeat of the Cybermen, feeling bad even after they had kept Earth safe and the timeline intact. (TV: Attack of the Cybermen)

Despite his high spirits, the Sixth Doctor did possess a melancholy side to him, believing that the universe would have gone on if he had stayed on Gallifrey, though admitted it would be in a different shape, and once desired only to fish instead of involve himself in another crisis. (COMIC: Time & Time Again)

When reading a newspaper, the Doctor would focus on the cartoons and crosswords. (AUDIO: Excelis Rising)

The Sixth Doctor considered his five predecessors to have been "good men". (PROSE: The Man Who Wouldn't Give Up) Although he would dismiss his third incarnation as "more interested in axle grease and looking in the mirror" than in reading, (AUDIO: Year of the Pig) and as having had a "strange taste in clothes", he was willing to acknowledge his superior skill in swordplay when the situation called for it. (PROSE: State of Change)

Immediately after his regeneration, the Doctor saw his new body as an improvement and felt that the Fifth Doctor had "a feckless charm that was never really [him]", (TV: The Twin Dilemma) but later admitted to Evelyn Smythe that "being him was like a holiday." (AUDIO: The 100 Days of the Doctor)

The Sixth Doctor held an admiration for the Seventh Doctor's confidence and forward planning, and his preparedness to do things he himself "would never do", but disliked his reputation as a planet destroyer, (AUDIO: The 100 Days of the Doctor) and thought him "selfish" for hunting big game with "live bait", (COMIC: Time & Time Again) but still thought him to be a "charming fellow". (AUDIO: The Light at the End) He also noted that he and the Eighth Doctor made a good team when dealing with the crisis caused by the Valeyard's machinations on Gallifrey. (PROSE: The Eight Doctors) He was critical of his thirteenth incarnation due to her vocabulary. (WC: Doctors Assemble!)

The Sixth Doctor did not suffer fools gladly, and sometimes seemed to endure the presence of others more than he enjoyed it. (TV: The Twin Dilemma, The Two Doctors, Timelash) However, he enjoyed his companions company, saying that Peri was important to him, and assuring her he wouldn't abandon her, (TV: The Mark of the Rani) had no problem saying that he loved Evelyn Smythe as a friend, (WC: Real Time) and refused to leave Constance Clarke in harm's way when she begged him too. (AUDIO: The End of the Line)

Though he was bitter for a while, the Doctor ultimately did not hold a grudge against Peri for her unintentional part in his predecessor's regeneration, telling her that he accepted the choice that the Fifth Doctor made and that "a universe with [her] brightness in it [was] infinitely preferable to a universe without". (PROSE: Burning Heart)

The Doctor had a soft spot for children, and once entertained local schoolchildren with various card tricks. (PROSE: Grave Matter)

While suffering from post-regeneration trauma, Peri Brown called the Doctor a "manic depressive paranoid personality", while Mestor described him as "egocentric, wilful and quite mad". (TV: The Twin Dilemma) When reflecting on his blue coat, Mel used "understated", "sombre", and "boring" as words not often associated with the Sixth Doctor. (AUDIO: The Wrong Doctors) On Thoros Beta, King Yrcanos noted that the Doctor thought like a warrior but did not act like one. (TV: Mindwarp) River Song described the Sixth Doctor as like "a clown put through a woodchipper". (GAME: The Eternity Clock) When the Eighth Doctor had a tarot card reading, the Sixth Doctor was identified as "the Moon". (PROSE: The City of the Dead)

described the Sixth Doctor as "the blustering one with the stupid coat", (GAME: Destiny of the Doctors) with calling him "the carnival clown". (AUDIO: The Two Masters) The Doctor's first TARDIS described the Sixth Doctor as "the retroaction". (AUDIO: Prisoners of Fate) The Valeyard described the Sixth Doctor as a "whirl of blunder and bluster". (PROSE: The Dark Scrolls of the Valeyard) Adam Mitchell identified the Sixth Doctor as the "madman" in comparison to his other incarnations. (COMIC: Unnatural Selection)

Upon learning that the Valeyard had infected his mind with the Nathemus to overwrite the Time Lords and trap them as formless beings in the Matrix, the Doctor willingly sacrificed his life to wipe out the Nathemus from his head, having no qualms about it if it meant stopping the Valeyard, openly taunting the Valeyard as he began fading from existence. Admitting he had "lived a good life by and large", the Doctor toasted the companions he had travelled with, while the Valeyard tried to tempt him not to die by pointing out he would be throwing away his "precious moral scruples", the Doctor decided these traits would die with him. Feeling his past self regenerating as timelines began to change, the last echo of the Sixth Doctor faded away in blissful peace, allowing himself to become reborn as the Seventh Doctor.

After being influenced by his future self to expose himself to fatal radiation, the Doctor, though distressed by the sudden attack from Lakertya, found peace in having lived with "a good innings", hoping the "footprint he [left]" would be "light, but apposite". However, when the manifestation of his next incarnation began talking, the Doctor reacted with confusion, unsure of who was there as he faded away. (AUDIO: The Brink of Death)

According to another account, after sacrificing much of his chronal energy to trap the Lamprey inside the Spiral Chamber, the Doctor, heavily weakened, tried to brush off Mel's concern by feinting prideful gravitas, but soon revealed to her that he was resigned to his fate, believing that his sacrifice was worth it to save the multiverse. As he took one last look at the universe, Mel protested that it was unfair for the Doctor to die the way he did but he testified that his sacrifice was his time to donate and his chance to give to the universe. Satisfied with the life he led as his sixth incarnation, the Doctor couldn't complain about his death this time and told Mel not to feel cheated by his untimely demise. (PROSE: Spiral Scratch)

Habits and quirks
Commonly, the Sixth Doctor would overreact with rage when questioned about his methods, repeating a single word from the criticism, often getting louder as each repeat went on. (TV: The Twin Dilemma, Attack of the Cybermen, The Mark of the Rani, Timelash) He also had a taste for poetry and literature, often reciting bits of them. (TV: The Twin Dilemma, The Mark of the Rani, Terror of the Vervoids, The Ultimate Foe)

The Doctor, when concerned with his appearance, often asked his companions how he looked in an act of vanity. (TV: The Twin Dilemma, The Mark of the Rani, Revelation of the Daleks)

The Doctor was prone to saying, "Mmm, I wonder...", when thinking aloud, and then exclaiming, "aha!", when his suspicions were proved correct. He was also known to let out an annoyed, "doh", when dismissing someone. (TV: Attack of the Cybermen, Timelash, The Ultimate Foe) As well as this, he had a tendency to exclaim, "Great Gallifrey!" (COMIC: The Gift)

For good luck, (PROSE: Time Wake) the Doctor would stroke his cat brooches before attempting something risky. (TV: The Twin Dilemma, Attack of the Cybermen, Vengeance on Varos)

Much like his previous incarnation, he would also stand with his hands in his pockets, also while flicking the long tails on his frock coat back. (TV: The Twin Dilemma, Attack of the Cybermen, Vengeance on Varos, The Mark of the Rani, The Two Doctors, Timelash, Revelation of the Daleks, Terror of the Vervoids) When not in his pockets, he would keep his hands hovering above his waist, wringing his fingers together. (TV: The Twin Dilemma, Attack of the Cybermen, The Mark of the Rani, The Two Doctors, Timelash, Revelation of the Daleks, The Mysterious Planet, Mindwarp, Terror of the Vervoids)

Something of a foodie, the Sixth Doctor was known to fill himself up on food, such as eating two biscuits meant for him and the Brigadier, and then "coyly eyeing [a] half-eaten custard cream", (PROSE: The Shadow in the Glass) and once devoured a burger in a single mouthful. (PROSE: Business Unusual) He once engaged in a series of adventures solely to acquire food without Mel knowing. (PROSE: The Man Who Wouldn't Give Up)

When relaxing, the Doctor would go fishing, especially for Gumblejack, which he considered amongst the tastiest fish in Mutter's Spiral. (TV: The Two Doctors; COMIC: Time & Time Again; PROSE: Business Unusual; AUDIO: Arrangements for War) However, the Doctor considered giving up fishing when he started thinking that it "wasn't fair on the fish". (AUDIO: The Wormery)

On occasion, the Doctor would carry a multi-coloured umbrella that matched the clashing colours of his clothing. (TV: The Two Doctors, The Mysterious Planet, Time and the Rani)

Skills
The Sixth Doctor was highly deductive, able to understand a situation based on small details that others overlooked, (TV: The Twin Dilemma, Vengeance on Varos, The Two Doctors, Terror of the Vervoids, The Ultimate Foe) and identify his location by studying his surroundings. (TV: The Two Doctors; AUDIO: Trial of the Valeyard) He was also able to see through attempts at deceptions. (WC: Real Time)

Despite his larger build, the Doctor still possessed the fighting skills of his predecessors, being able to overpower Azmael, (TV: The Twin Dilemma) one of Gustave Lytton's fake policeman, Russell, (TV: Attack of the Cybermen) Maldak, (TV: Vengeance on Varos) a wounded Stike, (TV: The Two Doctors) one of the Borad's androids, (TV: Timelash) and Davros's guards. (TV: Revelation of the Daleks) He was also able to disarm and defeat an attacker who was trying to claim the bounty on his head in an alleyway, (COMIC: The Shape Shifter) behead an Auton with a single punch, (COMIC: Façades) and knocked his opponent unconscious with three punches to the face while a contestant on Death-Hunt 3000. (PROSE: Time of Your Life) However, he recognised that he had little chance when fighting more experienced and prepared opponents, once allowing his third incarnation to take control of his body when he was forced to act as a gladiator in an alternate version of Rome. (PROSE: State of Change)

The Sixth Doctor's skin had extra subdural and subcutaneous layers, giving him a high level of damage resistance (PROSE: Burning Heart) and a high pain threshold. (AUDIO: Doctor Who and the Pirates) He was taught the Waltz and the Foxtrot by Becky. (PROSE: Teach Yourself Ballroom Dancing)

The Doctor was also a skilled hypnotist, able to put an erratic Jamie McCrimmon into a trance in order to extract information from him. (TV: The Two Doctors) He was later able to use hypnotism to calm a violent mutant human, but the mutation rendered the man unable to remain calm for long, (TV: Revelation of the Daleks) with the Doctor having much more success calming Melanie Bush after she was forcibly enraged by Doctor Prana's drugs. (AUDIO: Loud and Proud)

The Doctor had great mechanical skills, being able to briefly repair the TARDIS's damaged chameleon circuit. (TV: Attack of the Cybermen)

He knew how to perform first aid on a human. (PROSE: Synthespians™)

The Doctor developed a weak form of night vision from the carrot juice he had drunk over the years, (AUDIO: The One Doctor) and could measure distances via sound reverberation. (AUDIO: The Juggernauts)

He was also shown to have great acting skills, (TV: Attack of the Cybermen, Mindwarp, The Ultimate Foe) as well as being a decent singer, (AUDIO: Doctor Who and the Pirates) and organ player. (TV: Attack of the Cybermen)

The Doctor could place himself in suspended animation for at least twenty minutes, (PROSE: Killing Ground) knew how to operate a parachute, (PROSE: The Shadow in the Glass) could escape a straightjacket, (COMIC: Façades) and could pick a lock with a paperclip or a hairpin. (AUDIO: The Condemned, Industrial Evolution)

Appearance
Physically, the Sixth Doctor was identical in appearance to an incarnation of the Time Lord Maxil that the Fifth Doctor met with Nyssa, (TV: Arc of Infinity) being a tall man, with long, curly, blond hair, (TV: The Caves of Androzani) and green eyes. (PROSE: Business Unusual) Over time, the Doctor gained weight and his hair significantly grew out. (TV: The Mysterious Planet) Consequentially, Melanie Bush thought him overweight and forced him to undergo a vigorous fitness program, which he found annoying, taking every available opportunity to deviate from it behind Mel's back. (TV: Terror of the Vervoids)

Upon first seeing his reflection, the newly regenerated Doctor was pleased with his new face, describing himself as having "a noble brow," as well as "a firm mouth, [and] a face beaming with a vast intelligence". (TV: The Twin Dilemma)

Dibber described the Doctor as "a dilly in a long coat", (TV: The Mysterious Planet) and Sabalom Glitz described him as a "flashy, fair-haired person". (TV: The Ultimate Foe) Madame Razetskia described the Sixth Doctor as a "great handsome bull of a man", (PROSE: Endgame) while the Fifth Doctor described him as a "jester", (PROSE: Five Card Draw) and Death called him "the colourful jester". (PROSE: Love and War)

When Legion took on the appearance of the Sixth Doctor, William Blake saw him as "a fat, jolly fellow wearing a multicoloured coat". (PROSE: The Pit)

When Affinity took on the Sixth Doctor's appearance to approach the Twelfth Doctor, he noted that the sixth incarnation was a "large man in [a] garish coat". (PROSE: Silhouette)

Main attires
Much like his fourth and fifth incarnations, the Sixth Doctor wore a plain white shirt with cherry question marks embroidered on the collar, (TV: The Twin Dilemma) and braces adorned with question mark symbols. (TV: Vengeance on Varos) He took to wearing a set of royal yellow trousers with black stripes, and his generally preferred footwear was a pair of royal orange spats over forest green ankle boots. (TV: The Twin Dilemma) Sabalom Glitz confused his spats with "ankle armour". (TV: The Ultimate Foe) He wore size ten shoes. (AUDIO: The Wormery)

Most distinctive of the Sixth Doctor's attire was his patchwork frock coat, which had cuffs the same colour as his trousers and featured patches of crimson tartan, scarlet, green, pink and maroon felt, peach wool, a woven back piece, checked collar and amber and pink lapels, (TV: The Twin Dilemma) with a total of 76 different colour tones overall. (AUDIO: The Middle) The Tenth Doctor told Gabby Gonzalez that the coat was "at the height of sartorial elegance", (COMIC: Laundro-Room of Doom) and the Eleventh Doctor told Clara Oswald that his patchwork coat was "made for a spectrum invisible to the human eye", and that he had won an award for it. (COMIC: Dead Man's Hand)

The Doctor also included a range of waistcoats, oversized bow-tied cravats, and fob watches with coloured chains to accompany his patchwork coat, each possessing a different colour scheme and design. (TV: The Twin Dilemma, The Mysterious Planet, Terror of the Vervoids) He first wore a knitted waistcoat that was dark brown, orange and purple in colour and featured dark green buttons, along with a dark green metal watch chain and both a turquoise (TV: The Twin Dilemma) green, (PROSE: Tip of the Tongue) and a dark blue coloured polka-dot cravat. (AUDIO: Prime Winner)

After briefly wearing a shirt with blue question marks on the collar and a dark purple squared waistcoat with an orange cravat decorated with yellow polka-dots and pink hearts, (PROSE: Burning Heart) a waistcoat with tweed pattern on the right side and a zig-zag pattern on the left, (PROSE: Time Wake) a plain brown waistcoat, (COMIC: Virtually Indestructible) a plain purple waistcoat, (COMIC: Endgame) and another with a blue striped theme, (AUDIO: Year of the Pig) the Doctor's prominent waistcoat became a red and white gingham waistcoat with bear face buttons, with which he wore both his original cravat and a new neon green plastic watch chain, before replacing his turquoise cravat with a plain red polka-dot one and his green watch chain with a bright pink plastic one. (TV: The Mysterious Planet) After this waistcoat was ruined at the Network, he switched it for one striped with diagonal greens and oranges, (PROSE: Time of Your Life) and also donned a periwinkle purple cravat. (PROSE: Killing Ground) While travelling with Frobisher, the Doctor once wore a waistcoat that was blue on its left side, green on its right side and purple on its back. (COMIC: Time & Time Again)

During his travels with Mel, the Doctor wore both a pink, purple and green waistcoat with red ladybug buttons, a yellow cravat decorated with a starfield pattern and plastic watch chain that was a half neon green and half bright pink, (TV: Terror of the Vervoids) and an iridescent black and white waistcoat with a purple polka-dot cravat. (PROSE: The Quantum Archangel)

The Sixth Doctor's coat was the subject of much ridicule, with people often mocking it. (TV: The Twin Dilemma) Mel Bush and Peri Brown each thought the coat as resembling "an explosion in a paint factory", (PROSE: Instruments of Darkness; AUDIO: An Eye For Murder) though the Doctor insisted that there were places where his coat was considered the "height of fashion". (PROSE: Palace of the Red Sun) Peri once described the Doctor as "the worst dressed man in all of time and space", (AUDIO: Of Chaos Time The) with the Twelfth Doctor also showing a disgust for the Sixth Doctor's clothing, (PROSE: Silhouette) and the Fourth Doctor wondering how he could ever end up with "such a terrible sense of fashion" after seeing the Sixth Doctor's coat. (AUDIO: The Light at the End) When he appeared in the black and white film Swamp of Horrors, the Doctor commented that his "clothes were made for Technicolor". (PROSE: Swamp of Horrors (1957) - Viewing Notes)

Attending a funeral with Evelyn Smythe, (AUDIO: Real Time) the Doctor abandoned his multi-coloured coat for a more subdued blue one, alongside a plain white shirt, a dark blue waistcoat, gold metal watch chains, blue trousers and boots, and a plain turquoise cravat. (WC: Real Time) Adopting this as his regular attire, he took to also wearing this coat with both his original shirt, (AUDIO: The Doomwood Curse) and his blue shirt, (AUDIO: The Wrong Doctors) as well as with his purple, (AUDIO: The Condemned) dark blue (AUDIO: The Wrong Doctors) and turquoise polka-dot cravats, (AUDIO: The Crimes of Thomas Brewster) and a blue cravat decorated with starfield patterns. (AUDIO: Project: Lazarus) He would also occasionally swap the cravat for a black and grey striped necktie. (AUDIO: World Enough and Time) He would later resume wearing his original garb (TV: Time and the Rani) for the benefit of an amnesiac version of Mel, who liked his original outfit. (AUDIO: The Wrong Doctors)

Due to his fondness of cats, the Doctor always wore one of a number of cat-shaped pins or brooches on his left lapel. (TV: The Twin Dilemma, The Mark of the Rani, The Two Doctors, Revelation of the Daleks, The Mysterious Planet, Time and the Rani) He also wore cat cufflinks. (AUDIO: Trouble in Paradise) On occasion, the Doctor would carry a multi-coloured umbrella that matched the clashing colours of his clothing. (TV: The Mysterious Planet, Time and the Rani)

Other costumes
When he attempted to take Peri to London in 1899 for a holiday, the Doctor wore a dark frock-tailed suit and top hat. Moving on to London in 1936 to investigate the apparent conspiracy against Winston Churchill, the Doctor wore a dark-blue three-piece suit with a slight pinstripe, white shirt and regimental tie, yellow kid gloves, a walking stick, and a grey Homburg hat with a black band. He also wore a green tweed suit, and attempted to wear a brighter suit before Peri insisted he change to maintain their cover. (PROSE: Players)

While confronting the Sontarans in Seville, Spain in 1985, the Doctor removed his coat, left his cravat-less shirt unbuttoned, and replaced his usual waistcoat with an Hawaiian-styled one. (TV: The Two Doctors) He wore the same attire again whilst on Galápagos Islands with Evelyn Smythe. (AUDIO: Bloodtide)

On Necros, the Doctor briefly wore a large and eloquent royal blue cloak with gold trim over his usual attire as a sign of mourning for the death of Professor Arthur Stengos. (TV: Revelation of the Daleks)

Investigating strange technology in Washington, DC in the 1980s, the Doctor, on Peri's insistence, donned a black suit and multicoloured tie, the tie being printed with dozens of little cats. (PROSE: Blue Box)

While relaxing on the beaches of the planet Halcyon, the Doctor wore a pair of striped yellow trunks, along with a white shirt he kept unbuttoned. (COMIC: The Gift)

In place of his frock coats, the Doctor also owned a blue long-tailed jacket, with matching blue striped trousers. (AUDIO: Paper Cuts)

Trying to take Jamie to the Queen Elizabeth II, the Doctor donned a white tuxedo with a black bow tie. (AUDIO: The Wreck of the Titan)

While stranded in Victorian London, the Doctor wore a blue variation of the typical clothing of the time period while posing as Professor Claudius Dark. (AUDIO: The Hourglass Killers)

While undercover in Bletchley Park in 1944 after the TARDIS was rendered inoperative by a strange signal, the Doctor adopted a more subdued clothing of a brown and crimson tweed suit and waistcoat with a blue-and-white pinstripe shirt, along with a navy blue bow tie with scarlet spots. (AUDIO: Criss-Cross) The Doctor donned this attire again, referring to it as his "Bletchley Tweeds", when visiting Russia in 1947. (AUDIO: Quicksilver)

Casting
In 1983, Sylvester McCoy put his name forward in consideration for the Sixth Doctor. . He would later be cast as the Seventh Doctor and briefly played the Sixth Doctor in a regeneration sequence.

Circumstances
Colin Baker declined an invitation to film the regeneration sequence at the start of Time and the Rani due to the circumstances of his dismissal from the role. Wishing to play the Doctor for the whole of Season 24, he was instead offered one last full story to reappear and regenerate. Baker declined, reasoning that he did not want to make the audience think he was still the de facto Doctor for a sliver of 1987 when he had been removed from the series. His successor, Sylvester McCoy, donned a blonde wig and briefly appeared on screen as the unconscious sixth Doctor. McCoy's face was obscured from camera view, first by the TARDIS console and then by the regeneration FX, before the final reveal of the Seventh Doctor. McCoy thus became the first actor to play more than one incarnation of the Doctor. Paul McGann would later play both the Eighth Doctor and the War Doctor in the final moments of The Night of the Doctor (again with his face obscured by the camera placement). Also, Tom Baker has played both the Fourth Doctor and The Curator, though it is not completely confirmed that the Curator is, in fact, a future regeneration of the Doctor.

Following this, Colin Baker did not personally enjoy an official regeneration story until 2015, when he was approached to perform one in audio format, The Sixth Doctor: The Last Adventure. It provides an anthology of four stories spread out across various points in his Doctor's lifetime that are far distanced from each other in the grand scheme of the Sixth Doctor's life, but all play a part in ultimately setting the stage for his Doctor's sendoff, as a complex scheme by The Valeyard to take the Doctor's place via resources acquired across the universe forces the Sixth Doctor to trigger his own regeneration to prevent the Valeyard subverting his timeline. It also made Colin Baker, along with Paul McGann, one of two actors who played the Doctor to receive belated regeneration stories, and including John Hurt in that lineup as the War Doctor, whose introduction and regeneration were both deliberately done in a retroactive manner, one of three actors which portrayed the Doctor whose regeneration took place anachronistically.

The "bang on the head" myth
Due to lack of any information as to what caused the Sixth Doctor to regenerate, viewers were left to draw their own conclusions. At some point, it became the subject of ridicule that the Doctor had regenerated because he hit his head in some manner, an idea which some writers ran with, while others teased it. Some fans even joked it was because he fell off the exercise bike Mel had been forcing him to use since Terror of the Vervoids- the very subject was brought before Colin Baker himself, as evidenced by a YouTube video entitled "Colin Baker Reacts to his Regeneration (50th Anniversary Convention)" by MrTARDISreviews, which shows Baker found it disappointing.

Spiral Scratch by Gary Russell gives a "revisionist" account of the circumstances behind the Doctor's regeneration, explaining that it had not happened simply because he had hit his head, but was drained of the time-based life force that sustained him. Love and War by Paul Cornell offered a different explanation, indicating the Seventh Doctor had willed himself into existence by influencing the Sixth Doctor's demise.

The Brink of Death by Nicholas Briggs, a radiation lethal to Time Lords is the reason behind the Sixth Doctor's end. However, it did not appear to factor in the infamous "bang on the head" as an event coinciding with the Doctor's regeneration in any explicit way due to the fact it is not mentioned through dialogue nor possible to tell if the Doctor hit his head because there is no visual indicator of such a thing happening in the story. However, the Doctor is heard screaming in agony after being buffeted from a strong burst of radiation while a violent crashing sound is audible, proving he suffered some kind of physical trauma. Furthermore, though the Doctor soon afterwards collapses to the floor, there is no evidence of him hitting his head on the way down. It also seems to pull elements from Spiral Scratch and Love and War in terms of spoken dialogue and plot, as well as a charity publication by the late Craig Hinton and associates, Time's Champion.

If anything, the Doctor is either recalling his regeneration inaccurately or generalising it. The former is possible because not only does the stressful process of regeneration often hamper the Doctor's mind and ability to remember things correctly, the Seventh Doctor was subjected to a heavy dose of an amnesia-inducing drug by the Rani not long after regenerating that may have jumbled some of his memories in a lasting manner even after it was out of his system. Moreover, Mel did not witness him regenerate or learn why exactly he did so, robbing both of them of credible accounts of the regeneration. In addition, the latter becomes a possibility as the Doctor is known to lie, make light of events in a dismissive and/or joking manner and even make up things as he goes along as the Tenth Doctor later admitted in The Age of Steel, which further blurs the lines regarding the alleged and contested hit to his head.

Doctor Who: Legacy
In the story of Doctor Who: Legacy, the Sixth 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

 * According to an interview with Colin Baker in DWM 118, the Doctor's coat was created because John Nathan-Turner had the idea that it should be in "very bad taste" to show the Doctor's alien nature. Baker himself had wanted to wear black to display the Doctor's darker side.
 * More recently, Colin Baker has expanded upon this, stating that what he wanted to wear was pretty much what would become the costume for Christopher Eccleston's Ninth Doctor. (DOC: Doctor Who: The Ultimate Guide)
 * In AUDIO: The Curse of Davros, the Sixth Doctor was played by Terry Molloy as the Doctor switched bodies with Davros in an attempt to reform the Daleks. A similar event occurred in AUDIO: The Widow's Assassin, when the Doctor is portrayed for a time by Nicola Bryant, as the Doctor briefly transfers himself into the body of his companion Peri Brown to help her expel a neural parasite, correctly assuming that he will be better equipped to suppress the parasite than Peri.
 * Colin Baker related the character of the Doctor to a quote from Rudyard Kipling "I am the Cat who walks by himself, and all places are alike to me". This made him decide to wear a different cat badge on his costume in each story arc. He subsequently received a lot more cat badges from fans in the mail. When he played the Doctor on stage in 1989 these gifts gave him the opportunity to wear a different badge in every single performance.
 * The prose version of the character is one of few incarnations besides the Eighth who has technically crossed with the mythology of Faction Paradox and the War in Heaven. These instances are:
 * The Quantum Archangel, where Faction Paradox is mentioned and the Doctor experiences a timeline similar to the War. Craig Hinton's original notes for the novel, eventually published in the charity publication Shelf Life, asserted the War was negatively affecting the Six-Fold Realm of the Guardians. Hinton and Chris McKeon's Time's Champion utilised those notes and asserted the Sixth Doctor's regeneration, as well as the Seventh Doctor's role as Time's Champion, was due to the coming War.
 * Lawrence Burton's The Time Wrestlers, published in Obverse Books' A Target for Tommy, where the Doctor, Peri and Señor 105 face War-time agents of the Great Houses. This story loosely connects to Burton's novel Against Nature. The biodata virus from Interference - Book Two is mentioned.
