First Doctor

Holding himself in high regard, the First Doctor was prone to criticising those who he felt were naive or primitive compared to his intellect. However, after he began taking on companions, he developed a compassion, warmth, and wit that made up for his egocentric nature, serving to act as a mentor and guardian figure in his final years. Originally a very difficult and curmudgeonly person, the First Doctor matured from an apparent selfishness and became more inviting. His happier, kinder characteristics were fostered when he began to acquire an entourage of companions to accompany him throughout the wonders of the fourth dimension and learned to be a caregiver with a sense of justice in a universe afflicted by evils.

Beginning after he fled his home world of Gallifrey, his travels through time and space were mostly random owing to faulty components in his TARDIS. Initially, he travelled only with his granddaughter Susan Foreman. They settled for a time on Earth in 1963, where Susan was a student at Coal Hill School. He was forced to abruptly depart from Earth with Susan's teachers, Ian Chesterton and Barbara Wright, kidnapping them from their own time after they went to investigate their unusual pupil. After much travel with Ian and Barbara, he bade Susan farewell to allow her to live a happier life with a man with whom she had fallen in love.

Following Susan's departure, the Doctor travelled for a short time with Ian and Barbara, before landing upon the planet Dido, where he invited a new travelling companion to join him, Vicki. She reminded him of Susan, and the Doctor saw her as a surrogate to fill her spot in his travels with Ian and Barbara. Later, during a confrontation with the Daleks, the Doctor used one of their time machines to return Ian and Barbara to their proper time - something he had been unable to manage with his TARDIS.

Soon after the departure of Ian and Barbara, the Doctor and Vicki had gained a new companion in Steven Taylor, with whom the Doctor had a relatively uneasy relationship. Vicki eventually left the Doctor's company as well, also after falling in love with a man she met in Ancient Troy. After a lengthy fight with the Daleks, Steven soon became bitter towards the Doctor, blaming him for the deaths of their travelling companions Katarina and Sara Kingdom, but eventually forgave him. They were then joined by Dodo Chaplet. Ultimately, Steven decided to stay to help a civilisation they had encountered, while Dodo was later injured in an adventure and decided to remain home in her own time, while the Doctor found himself joined by Ben Jackson and Polly Wright, to whom he was much more kind; he hoped to prevent them from leaving as Steven had.

The First Doctor met his end after his battle with the Cybermen in Antarctica caused a loss of strength to maintain his ancient body due to Mondas draining a large portion of his life force. Initially, he refused to go through with the change until an encounter with a future incarnation also refusing to regenerate caused the Doctor to witness the type of person he would soon become. As a result, his fear of the change was turned to reassurance for his future, causing him to accept his regeneration into his next body.

Life on Gallifrey
Due to the various alterations the Doctor made to his timeline while travelling through time, what really transpired to the Doctor during his time on Gallifrey was hard to decipher. (PROSE: Celestial Intervention - A Gallifreyan Noir)

Youth and upbringing
The Doctor was born on Gallifrey, home planet of the Time Lords, (TV: The War Games, The Time Warrior, Death in Heaven) "the oldest and most mighty race in the universe", (TV: The Sound of Drums) on the Holiday of Otherstide (AUDIO: Cold Fusion) under a name that he concealed in despair. (TV: The Shakespeare Code) He was born under the sign of Crossed Computers, the symbol of the maternity service. (TV: The Creature from the Pit) He was "a high born Gallifreyan", (TV: Hell Bent) born "into wealth and privilege". (TV: Robot of Sherwood)

According to one account, the Doctor was a genetic reincarnation of the Other, and was loomed into the House of Lungbarrow (PROSE: Lungbarrow) in the form of a small child. (PROSE: Human Nature) The Fifth Doctor recounted his birth to Patience, telling her that he was "born at Otherstide through the Loom of the House of Lungbarrow in Southern Gallifrey." (AUDIO: Cold Fusion) As the Eleventh Doctor told Amy Pond and Rory Williams, he slept in a cot as an infant. (TV: A Good Man Goes to War)

The Doctor stated he had a mother and father, (TV: Doctor Who) as well as a family (TV: The Tomb of the Cybermen) and childhood, (TV: The Sound of Drums) but also confessed his uncertainty on whether his family was real or a dream. (PROSE: Unnatural History) He had at least one brother, Irving Braxiatel, (PROSE: Tears of the Oracle) an uncle, (TV: Time and the Rani) sisters, (TV: Arachnids in the UK) and seven grandmothers. (TV: It Takes You Away)

The Eighth Doctor claimed many times that he was half-human on his mother's side, (TV: Doctor Who; PROSE: Alien Bodies, The Infinity Doctors, The Scarlet Empress, Unnatural History, The Shadows of Avalon, Grimm Reality) though he also questioned the accuracy of these statements, (PROSE: Autumn Mist) once claiming his statement to be a ruse to trick, (COMIC: The Forgotten) with his eleventh incarnation identifying his mother as a Time Lord. (COMIC: The Comfort of the Good) Ashildr would also speculate the Doctor was a half-human half-Time Lord hybrid, something the Twelfth Doctor neither confirmed or denied. (TV: Hell Bent)

According to his third incarnation, the Doctor lived in a "house that was perched halfway up the top of a mountain" in the mountains of South Gallifrey. (TV: The Time Monster, Planet of the Spiders) Known as the House of Lungbarrow, this house was one of the Ancient Oldblood Houses and overlooked the Cadonflood River. (PROSE: Lungbarrow) He grew up in Lungbarrow with his family. (PROSE: Lungbarrow, Unnatural History) A lonely and depressed youth, the Doctor did not get along with his family, being bullied by many of his cousins, who would call him cruel names to reflect the fact that the Doctor had been loomed with a belly button. (PROSE: Lungbarrow)

As a Time Tot, the Doctor played hide and seek with, with his ninth incarnation recalling that his skill at finding her "drove [her] nuts". He held the Time-Tot hide and seek championship for forty-two years in a row. (COMIC: Weapons of Past Destruction) He also believed humans to be a myth as a Time Tot. (PROSE: The Shining Man)

As a child, the Doctor would play conkers. (TV: The Highlanders) He also toyed with trains, (TV: The Evil of the Daleks) and had a dream to one day drive one. (TV: Black Orchid) Amongst his favourite bedtime stories were The Three Little Sontarans, The Emperor Dalek's New Clothes and Snow White and the Seven Keys to Doomsday. (TV: Night Terrors) He played in the tunnels under the Panopticon as a child. (AUDIO: Order of the Daleks) He also watched a meteor storm on Gallifrey with his father. (TV: Doctor Who)

When he was just a "small child", the Doctor's mother told him the story of Grandfather Paradox, a story which scared the Doctor so much that he worried that Grandfather Paradox was hiding in his wardrobe or under his bed. (PROSE: The Gallifrey Chronicles) Granny Five, the Doctor's favourite among his seven grandmothers, told him bedtime stories about the Solitract, at night when he couldn't sleep. (TV: It Takes You Away) The Doctor, as a child, was frightened by the "mythological horror" stories about the Fendahl, (TV: Image of the Fendahl) looked to Omega as his people's greatest hero, (TV: The Three Doctors) and was told stories of the Pantheon of Discord. (TV: The Wedding of Sarah Jane Smith) He drew crayon sketches of the Solvers, based on the stories, which the Eighth Doctor later suggested did not do the real thing justice. (AUDIO: The Doomsday Chronometer)

The Doctor also had nightmares for years about an elderly lady who had been covered in veils after she died on a hot day, with the heat causing flies to swarm around her corpse. (TV: Heaven Sent) The Doctor spent a lot of time by the sea as a boy, where he believed the dead were out there, whispering to him from the waves. (PROSE: Matrix)

During his formative years, the Doctor was "brain-buffed" at his home by his Avatroid Tutor, Badger. During this time, the Doctor was forced to learn by rote and was taught about the Legacy of Rassilon and the story of Otherstide. The young Doctor disliked this form of learning and would often cause distractions and try to escape his lessons. (PROSE: Lungbarrow)

During his childhood, before joining the Academy, the Doctor would leave his house, going to sleep in a barn (TV: Listen) in the Drylands. (TV: Hell Bent) A Gallifreyan boy was told that the Doctor lived there for a time. (PROSE: A Brief History of Time Lords) The Doctor wept over his fears in the barn, (TV: Listen) and was the "only child left out in the cold". (TV: The Empty Child) When Madame de Pompadour read the Tenth Doctor's mind, she said he had been "such a lonely little boy." (TV: The Girl in the Fireplace)

One night while weeping in the barn, he pretended to be asleep when two adults came looking for him. After they left he, in response to a noise, moved to get out of the bed, only for a hand to grab his leg and for its owner to tell him to get back into bed and that he was dreaming. Moments later he would be comforted by this stranger who gently told him it was fine to be scared, that fear is a superpower, and that he should always "listen". Then the stranger vanished and, the Doctor sat up in response to another noise. He would remember parts of this experience for the rest of his life. It would both inspire him, and lead him to suspect that there was a creature that was a 'perfect hider' in the universe, giving him a fear of the dark. He also came into a possession of a toy soldier who represented a 'soldier so brave he didn't need a weapon'. (TV: Listen)

He had at least two imaginary friends, named Binker (AUDIO: The Abandoned) and Mandrake. (AUDIO: The Widow's Assassin)

Education
Like all Time Lords, the Doctor was taken from his family at the age of eight for the selection process. (PROSE: A Brief History of Time Lords) Staring into the Untempered Schism as part of a Time Lord initiation rite, he reacted by running away. (TV: The Sound of Drums)

The Doctor attended the Time Lord Academy as a member of the Prydonian Chapter, and received tutelage from Borusa, (TV: The Deadly Assassin) and Azmael. (TV: The Twin Dilemma) While the Tenth Doctor claimed that he spent "centuries" at the Academy, (COMIC: Mortal Beloved) Maris also found evidence that his time at the Academy had only been twenty years. (PROSE: Celestial Intervention - A Gallifreyan Noir)

On his first day at the Academy, (TV: World Enough and Time) the Doctor formed strong friendships with both the Master and the War Chief. (PROSE: Divided Loyalties) The Master soon became the Doctor's "man crush", and the two friends formed a pact to see every star in the universe together. (TV: World Enough and Time) While he was "little", the Doctor and his friend, the Master, ran together (TV: Death in Heaven) across the fields of the Master's estates by Mount Perdition. (TV: The End of Time) The Master would often hypnotise others, and the Doctor would un-hypnotise them, having learnt hypnotism from the Master. (PROSE: The Dark Path) Alongside other friends, the Doctor would ride a skimmer. (AUDIO: The Paradise of Death)

While at the Time Lord Academy, the Doctor spent four days in the Cloisters, where he talked to the Cloister Wraiths, who told him of the prophecy of "the Hybrid," and showed him a secret passage out. According to his twelfth incarnation, the experience drove him "completely mad," and he was "never right in the head again" afterwards. (TV: Hell Bent)

claimed that while growing up, the Doctor started calling himself "Doctor Who" to "sound mysterious", but "dropped the 'Who' when he realised it was a tiny bit on the nose." (TV: World Enough and Time) In choosing the name of "the Doctor", he also made a promise to himself to "never [be] cruel or cowardly" and to "never give up, [and] never give in." (TV: The Day of the Doctor) He also received the nickname "Theta Sigma", or "Thete" for short, from his friends at the Academy, (TV: The Armageddon Factor, The Happiness Patrol) using it to identify him uniquely amongst other Time Lords. (PROSE: Falls the Shadow)

During his first year at the Academy, the Doctor gained a troublesome reputation by trapping his teacher in a time-loop for a day, (PROSE: Island of Death) and "mucking about" with space-time portals, something the Tenth Doctor indicated were easy to create. (PROSE: Made of Steel) He also frequently played "truant" to drink with the Shobogans, visit the hermit on his mountain, and venture into Low Town with the Master. (PROSE: The Eight Doctors)

At the age of ten, the Doctor was "caught skinny-dipping with a pretty female cousin of [an] acquaintance". (PROSE: Unnatural History)

Genniploritreludar taught the Doctor Stellar Engineering at the Academy, once asking him to recite the fifteen stages in the life cycle of the main sequence sun. (PROSE: Original Sin)

On "the blackest day of his life," he went to visit a hermit on the side of the mountain his family's house rested on in South Gallifrey. While climbing the mountain, the young Doctor saw only dull coloured rocks and weeds. However, the Hermit gave no words of advice when he heard the Doctor tell him all his troubles, but instead pointed at a flower, which the Doctor had dismissed as a weed. As he descended the mountain, the world no longer seemed so grim to him and the Doctor noticed the colours of the rocks and the vibrancy of life in the flowers. (TV: The Time Monster) The Doctor spent what he felt where some of the finest hours of his life with his guru, being taught how to look into his own mind and being told ghost stories about the King Vampire. (TV: Planet of the Spiders, State of Decay)

At the age of thirty, the Doctor asked K'anpo Rimpoche the name of the mountain on which he dwelled. He had been told by Old Lady Nine Teeth that it was called Plutarch, where his cousins called it Lung, and his friends at the Academy called it Mount Cadon. His mentor told him that the mountain had all three names, and told him that whatever he called it would determine the way in which it was climbed. (PROSE: The Three Paths)

The Doctor left the Gallifreyan equivalent of primary school aged forty-five. (PROSE: Shroud of Sorrow)

Still a "small boy", the Doctor wrote a treatise on the chromosomal origins of love. His tutor said that he missed the point entirely and gave him a "rubbish" grade. (AUDIO: The Wormery) When he was "just a kid" of ninety, he visited the Medusa Cascade. (TV: The Stolen Earth) The Eighth Doctor stated that he was a terror until the age of one-hundred-and-twenty, claiming that he was a late developer. (AUDIO: The Next Life) As his fourth incarnation recalled, the Doctor was a "spotty teenager" for fifty years. (COMIC: Doctor Who and the Time Witch)

When the Doctor was a young boy, Borusa told him off for his attitude, and that he would be lucky to receive a Class Three Doctorate. Borusa taught him to be seen to respect tradition, even though he did not, (COMIC: Vortex Butterflies) and also gave him a lecture on regeneration, telling the Doctor; "You will walk into a storm and a stranger will walk back out. And that stranger will be you." Borusa also told him to "never break eye contact with a shape-shifter", as he would "see it everywhere [he] look[ed], and [would] never be able to trust anyone again". (PROSE: The Day of the Doctor)

At the Academy, he and the Master joined the "Gallifrey Academy Hot Five" band, with the Doctor playing the lead perigosto. (PROSE: Deadly Reunion) He once attended a party on the Moon of Korpal, and met fellow academy student, Rummas, but was too drunk to remember. Soon after, he and Rummas began sharing Borusa as a tutor. (PROSE: Spiral Scratch) He was also part of the same zero-grav hyperball team as Padrac. (AUDIO: The Eleven) At some point in his youth, the Doctor became addicted to using vortex manipulators. The Eleventh Doctor once described his past self as "40-a-day man". (COMIC: Space in Dimension Relative and Time)

He and the Master also enjoyed building "time flow analogues" to disrupt each other's experiments. (TV: The Time Monster) At the Academy, the Doctor would often skip classes to practice yo-yos and juggling. (PROSE: Match of the Day)

The Doctor was taught at the Academy that "the universe [was] nothing but a functional chain of causality at every level, governed by the oldest and simplest laws," by a tutor the Eighth Doctor would later describe as "the most attractive person [he'd] ever seen", but the First Doctor retorted that, however much people tried to take the mystery out of things, they could not "diminish wonder, beauty and discovery." (PROSE: Longest Day) He also rode Vortisaurs bareback at the Academy, (AUDIO: Storm Warning) and played games with the principle of transmigration. (PROSE: Interference - Book One)

At the Academy, the Doctor conducted an experiment in which he created a bacteria known as the Ablative, with the ensuing scandal nearly getting him expelled until it was covered up by the Academy, who believed that all of the samples had been destroyed. (AUDIO: Planet of the Rani)

In his fiftieth year at the Academy, the Doctor made an enemy of his fellow student, Valyes, after he fed a snapping wart fowl to Valyes' summer project. (AUDIO: The Next Life)

The Doctor didn't attend his time-travel proficiency lesson, which made him unqualified to operate a TARDIS, and rejected an offer to retake the lesson. (PROSE: Festival of Death) The Doctor also failed practical theology, but was highly commended for landscape gardening, (PROSE: All-Consuming Fire) and received a poor grade in Time Lord philosophy. (PROSE: Infinite Requiem) He received training in emotional detachment, (TV: The Invasion of Time) and was on the tech course with Drax. (TV: The Armageddon Factor)

The Doctor and the Master were bullied as children by Torvic and the Doctor was forced to kill Torvic to save his friend's life. He was later confronted by Death, who insisted he become her disciple. The Doctor refused and asked for Death to take away his guilt, causing her to transfer the memory of committing the crime to the Master instead. (AUDIO: Master)

The Doctor was also bullied by Anzor, who used a torture device called "the galvaniser" on his classmates to ensure that they did as he said. He particularly bullied the Doctor, forcing him to do his navigational homework as he was "too stupid to do it himself". He used the galvaniser on the Doctor at least once, as he later threatened to "revive your memory of my galvaniser" to terrify the Sixth Doctor. (AUDIO: Mission to Magnus)

On one occasion, he and the Master travelled into Gallifrey's history in search of Valdemar, a dark mass of life created by the Old Ones in the higher dimensions, which swept across creation and wiped out the Old Ones. They met a surviving Old One, who warned them of Valdermar's powers. The Doctor was shaken and was horrified that the Master seemed fascinated by its power. (PROSE: Tomb of Valdemar)

According to a nightmare the Fifth Doctor had under the Celestial Toymaker's influence, the Doctor first learned of the Toymaker when he was a youth at the Prydonian Academy. The Time Lords' data banks described him only as a vague legend. The Doctor and his friends Rallon and Millennia investigated the legend, travelling to the Toyroom in a stolen TARDIS. The Toymaker was in a dormant, disembodied state, but on their arrival, he possessed Rallon and made Millennia one of his living toys. The Doctor defeated him, and the Toymaker allowed him to leave, knowing that he would become an even more worthy opponent given time to mature. (PROSE: Divided Loyalties)

The Doctor wanted to be an explorer when he was young, but because the Time Lords had already explored every time and place, he didn't believe there was any point to him becoming an explorer too. He then found a reason and whenever he felt hopeless, he remembered that reason. (PROSE: The Frozen Wastes) Despite this, the Doctor would later claim to have been a pioneer amongst his people, (TV: The Rescue) due to the subconscious memory of his life as the Other. (PROSE: Cold Fusion, Lungbarrow)

When the Time Lords created the Consolidator to conceal various dangerous historical secrets from the rest of the universe, unwilling to destroy the items or races in the ship in case they proved useful later, the Doctor and the Master were assigned to come up with a solution where their peers failed. The Master had the idea of using a black hole to tear a rift in time and send the Consolidator into the distant future, where the future Time Lords could deal with it, but the Doctor declined to have his name put down on the calculations as he questioned the ethics of the assignment. However, when the experiment was actually attempted, the Consolidator was apparently destroyed by a mistake in the calculations when it struck the edge of the black hole, leaving the Time Lords to hush the matter up. (PROSE: Harvest of Time)

The Doctor was also known to have attended the Prydonian Academy with the Master (PROSE: First Frontier) and the Rani. Thermodynamics was his special subject. (TV: Time and the Rani)

The Doctor earned a Higher-Dimensional Physics degree at "Time Lord University". He was required to learn how to envision a superimposed array of 208 different 43-dimensional supersolids, taking eight years to master the skill. (COMIC: The Friendly Place)

Ultimately, the Doctor did not have an impressive career at school, passing his qualifying exams to become a Time Lord with only 51% — the lowest possible pass mark — on his second attempt. (TV: The Ribos Operation) However, this was a deliberate ploy to not to draw undue attention to himself, so he could eventually leave Gallifrey. (PROSE: Tears of the Oracle)

Family life
The Doctor was married to an unidentified individual; with Clara Oswald counting a fourth marriage alongside his successors' wives when trying to convince the Cybermen that she was the Doctor. (TV: Death in Heaven) His tenth incarnation recalled being "terrible" at his own wedding. (TV: Blink)

Several accounts suggest the Doctor was a father at one point in his life, (TV: Fear Her, The Doctor's Daughter, Listen) of both "sons and daughters". (PROSE: The Eleventh Tiger) The Doctor also had three known grandchildren: Susan, (TV: An Unearthly Child) John and Gillian. (COMIC: The Klepton Parasites) Clara Oswald also referred to the Doctor's "children and grandchildren", who were "missing" by the time of the Doctor's twelfth incarnation. (TV: Death in Heaven)

While Susan specifically identified the Doctor as her grandfather, (TV: "An Unearthly Child", "The Escape") and the Doctor likewise considered Susan to be his grandchild, (TV: "The Rescue", Marco Polo, The Sensorites, "Flashpoint") documents on Gallifrey were deliberately obscure about Susan's real family, some theorising that she was a direct descendant of a founding father of Gallifrey alongside a claim one of her parents was the President of the Time Lords. (PROSE: A Brief History of Time Lords) According to, Susan was a young Time Lady from the Doctor's own time whom had stowed away on the Doctor's TARDIS, (PROSE: Birth of a Renegade) while other accounts had her being rescued from the time period of the Other by the Doctor, (PROSE: Lungbarrow) who later adopted her as his granddaughter. (PROSE: The Longest Story in the World)

After his friend, the Master, had a daughter of his own, the Doctor gave him a cameo brooch made of Dark star alloy. (TV: The Witch's Familiar) The Doctor also brought Susan to watch him and a group of Prydonians perform a ritual in Arcadia. (AUDIO: The Toy)

Career
The Doctor worked as a Scrutationary Archivist in the Bureau of Possible Events, (PROSE: Lungbarrow) and rose high in the ranks of the Time Lords, (PROSE: The Eight Doctors) until he was considered a "superior" on Gallifrey by some, (COMIC: Flashback) with his second incarnation claiming to have held a seat on the High Council during the "latter years of [his] first incarnation". (PROSE: World Game) He also made powerful enemies due to his controversial views on the Time Lords' non-interference policy, even being accused of being a meddler. (AUDIO: The Beginning) He also lost popularity when he voiced his opinions on evil being a genuine force to his contemporaries, who found "such black and white notions of morality" to be "archaic". (PROSE: Strange England) He possessed a Type 50 TARDIS, which he abandoned when he left and became a renegade. (AUDIO: Prisoners of Fate)

The Doctor learned of the existence of the miniscopes and was outraged by their cruelty to the specimens within. He campaigned to have them banned and, despite the non-interference policy of the Time Lords, was successful. (TV: Carnival of Monsters) His role in banning the use of miniscopes was known throughout nine galaxies. (PROSE: The Empire of Glass) He also successfully campaigned on Gallifrey to ban a chemical of Time Lord invention which converted vertebrae blood into acid, the formula for which he was never able to forget. (PROSE: The Age of Ambition)

On one instance, he saved a glowing life form from being killed by his old friend Magnus, resulting in a fallout between the two. (COMIC: Flashback) The Doctor later rescued Patience and her granddaughter from danger in Gallifrey's past. (PROSE: Cold Fusion) At some point, the Doctor fought in a war. (AUDIO: The Sontarans)

Eventually, the Doctor came to live in a small house on a mountain with his "adopted granddaughter", Susan, who was described as coming from a distant and primitive time. Susan would tell the Doctor tales of him "building" the TARDIS and leaving their planet, becoming younger again and fighting monsters. Susan's tales became known by the guards of the High Council, and, after an incident outside the Capitol, the Doctor found that armed guards had infiltrated his house. (PROSE: The Longest Story in the World)

According to reports found by Maris, the Doctor was involved in a riot, and become wanted by the Celestial Intervention Agency for "interfering in non-time-travel-capable species' development". He left Gallifrey two days afterwards. (PROSE: Celestial Intervention - A Gallifreyan Noir)

Leaving Gallifrey
According to Ashildr, when he was "barely more than a child", the Doctor learned of a prophesied warrior called "the Hybrid" from the Cloister Wraiths and the story made him "so scared" (TV: Hell Bent) that he eventually left Gallifrey out of fear, (TV: Heaven Sent) and to find out if "some mysterious force" was the reason why "good prevail[ed]" over "evil" in the universe, (TV: Twice Upon a Time) leaving during "dark times when [his] world tottered on the edge of ruin, where the impotence of [his] own people had driven him to leave". (PROSE: Roses) To keep his secrets, the Doctor lied that he left his home planet because "[he] was bored". (TV: The War Games, The Witch's Familiar, Heaven Sent, AUDIO: The Dalek Occupation of Winter) As the Fifth Doctor told Tegan Jovanka, his travels all started when he "deliberately [chose] to go on the run from [his] own people in a rackety old TARDIS", with Flavia hinting that he began running after being offered the Presidency, (TV: The Five Doctors) and the Eighth Doctor claimed to have left his planet because he "disagreed with the philosophy of its Masters" (PROSE: Beltempest) with the Second Doctor admitting to leaving due to "the deviousness and corruption of Time Lord politics". (PROSE: World Game) The First Doctor would later clarify that there were "many pressing reasons" for his departure from Gallifrey. (TV: Twice Upon a Time)

According to, the Doctor left Gallifrey on a whim because an unlocked TARDIS was nearby, (AUDIO: The Light at the End) while Clara Oswald told Robin Hood that the Doctor "was moved to steal a TARDIS [and] fly among the stars, fighting the good fight" because he "[found] the plight of the oppressed and weak too much to bear", something the Twelfth Doctor did not dispute. (TV: Robot of Sherwood) The Doctor grew a bond with that TARDIS, describing it as "the most beautiful thing [he] ever saw" upon first entering it, (TV: The Doctor's Wife) after stealing it from a TARDIS repair shop at the Boulevard of Grand Milieu. (PROSE: Celestial Intervention - A Gallifreyan Noir)

The Doctor also took the Hand of Omega, (TV: Remembrance of the Daleks) some validium, and Gallifrey's moon when he left, (PROSE: A Brief History of Time Lords) and brought Susan with him as an accidental passenger, (AUDIO: Here There Be Monsters) deciding it was best to do so to prevent her from being brainwashed and regimented in the thought patterns of the Time Lords. (PROSE: Legacy of the Daleks) He also took his signet ring with him, using it to breach the "laws and barriers" to enable his escape. (PROSE: The Three Paths)

Conflicting stories
By Iris Wildthyme's recollection, the First Doctor's hair was "not even white yet", and even still "a bit of a bruiser", when he left Gallifrey and began his wanderings. (PROSE: The Scarlet Empress)

In an account presented by, the Doctor existed during a period of civil unrest on Gallifrey, when many students of the Time Lord Academy, led by the Master, revolted against the corrupt Lord President Pundat the Third, and attempted to convince the Doctor to take the position as President, but he decided not to interfere with the current constitution. When Pundat died of stress soon after the revolt, his chosen successor was Chancellor Slann. The students had found the last of Lord Rassilon's descendants, Lady Larn, a seven-year-old child adopted by Councillor Brolin, and decided on a second coup. However, their attempt to convince the Doctor to participate in another coup was overheard and reported to Slann, and the students were "brutally put down" by the Citadel guards, though the Doctor was too highly respected to be terminated, so it was decided to wipe his memory. Bloody reprisals against the students followed, and the Doctor decided to leave Gallifrey in a TARDIS. As it happened, Lady Larn was hiding in the same TARDIS that the Doctor stole, and affectionately called him "grandfather". (PROSE: Birth of a Renegade)

A second account had the Doctor and Susan already on Gallifrey, fleeing to keep the Hand of Omega safe from those who would misuse it and running straight towards the TARDIS with no hesitation. (COMIC: Time & Time Again)

An account from an Astral Projection of the Doctor's life depicted the Doctor living as a lowly Scrutationary Archivist of the Bureau of Possible Events. He had been disowned and banished from his home by his family in the House of Lungbarrow. In order to replace the disowned Doctor, his family illegally loomed another cousin, Owis. Upon learning of this crime, the Doctor reported his family to the Prydonian Chapter. After an encounter with his gloating Cousin Glospin, Glospin revealed that there was genetic evidence to suggest that the Doctor didn't originally come from the Lungbarrow Loom, having originally been naturally born. Glospin claimed that the Doctor had infiltrated the family, and intended to use his evidence to get the Doctor executed for Loom-jumping. Glospin attacked the Doctor, obtaining a sample of his DNA, allowing him to frame the Doctor for the murder of their House Kithriarch, Quences. During the fight between the two, the Hand of Omega arrived to attack Glospin, giving the Doctor the opportunity to escape. Knowing Glospin's claims could lead to his execution, the Doctor left Gallifey, declining the chance to take a Type 53 TARDIS in the process. However he passed up on the opportunity to take this TARDIS and he chose to leave in a Type 40 TARDIS with the Hand of Omega. The Hand piloted the TARDIS to the Dark Time on Gallifrey to collect the granddaughter of the Other, who recognised the Doctor as the reincarnation of the Other, and the two left Gallifrey together in the TARDIS. (PROSE: Lungbarrow)

When the Eighth Doctor recalled his departure from Gallifrey while recovering from amnesia, the First Doctor was shown angrily striding down the corridors of the Capitol after a meeting in the Council Chamber. He found a TARDIS deep beneath the Capitol, and just as he was about to close the door behind him, heard Susan telling him she was coming with him. Shortly after remembering these events, the Eighth Doctor confronted his younger self about his motives for leaving Gallifrey, accusing him of having decided to do so in a fit of pique because even his fellow Council members could no longer tolerate his arrogance, and had told him as much. Somewhat conflicting with his earlier recollection, he further berated the First Doctor for having chosen to take Susan with him due to thinking her company might be pleasant without considering the consequence for the young girl. (PROSE: The Eight Doctors)

Gideon Crane, a human temporarily fused with the Eighth Doctor's memories, stated that the Doctor left Gallifrey due to "some misplaced revolutionary fervor". (AUDIO: Minuet in Hell)

Another account suggested that the Doctor broke the Time Lords' law on non-interference and faced being erased from history by his brother Braxiatel on the order of Lord President Pandad VII. Braxiatel allowed the Doctor to run, giving him the chance to steal a Type 40 TARDIS and escape Gallifrey. (AUDIO: Disassembled)

One account showed the Doctor, already with Susan and already wearing Victorian era clothing, ready to steal a faulty TARDIS in a repair shop on Gallifrey. (TV: The Name of the Doctor) The Doctor had brought the flying trunk containing the Hand of Omega with him and Susan had brought basic luggage from her house. Armed guards chased the fugitive Doctor and Susan into the repair shop, where the only place for them to hide was a line of TARDISes. Susan walked into one TARDIS, but the Doctor didn't follow her inside, (AUDIO: The Beginning) as he was being advised by a version of Clara Oswald to steal the Type 40 with the faulty navigation system instead of the one Susan had walked inside, as it would be much more fun. (TV: The Name of the Doctor) The Doctor speculated that the TARDIS was deregistered, and that was how it slipped through Gallifrey's transduction barrier and how they evaded the Time Lords. (AUDIO: The Beginning)

First flight
Now cut off from his home planet "without friends or protection", the exiled Doctor intended for him and Susan to someday return, (TV: An Unearthly Child) but he knew that he could not. (TV: The Massacre) When he left Gallifrey, the Doctor lost his right to have his mind absorbed into the APC Net at the time of his death (PROSE: Original Sin) and, according to Clara, his "Prydonian privileges were [also] revoked when [he] stole a time capsule and ran away". (TV: Death in Heaven)

According to one account, the first flight of the TARDIS involved the Doctor pulling a lever which turned the TARDIS into a time-travelling machine. During early flights, he would have test instruments connected to the ship to calibrate the controls. (COMIC: Timeslip)

According to another account, immediately after leaving Gallifrey, the Doctor rested in the TARDIS console room, while Susan explored their new home. She found a full-length mirror and saw a pale-skinned fanged figure who vanished after telling her that she was not "the one". The Doctor theorised that, since they were now travelling through time, she encountered a brief echo of either the future or the past. (PROSE: The Exiles)

According to a third account, Susan collapsed in the TARDIS shortly after the engines were stabilised. The Doctor tended to Susan as she slept, and used his jacket as a makeshift pillow for her before she reawakened. Susan then explored the TARDIS as the Doctor tended to the ship's controls. She tripped over a rigger's work case and brought it back to the Doctor when the TARDIS had run out of power. Inside the work case, the Doctor found an artron cell and attached it to the drive system to power an emergency landing. After finding a nearby world, the TARDIS appeared to take over and brought them to the Moon. (AUDIO: The Beginning)

First destination
According to one account, the Time Lord met humans for the first time on the planet Iwa when he and his granddaughter were separated. In his search for his granddaughter, the Time Lord found a human medical colony. The principal work of the facility, called "the Refuge", was to rehabilitate patients identified as "Future Deviants". By undergoing dream therapy, it was hoped that such individuals would not become criminals. The Time Lord soon learned the residents were besieged by fox-like aliens who could disintegrate and reconstitute their bodies.

Taking him inside their compound, the humans stripped him of his clothes and burned them, citing possible contamination by the "foxes". They gave him new clothes drawn from their own supply. This meant that he was now wearing the garb of a doctor. When they assumed that he was sent from Earth to help them, he agreed. Not wishing to give them his real name, he referenced his new clothes to derive a title: "the Doctor". The Time Lord assumed this alias because he described it as an honourable profession amongst his own people.

He agreed to help them with their "fox problem" if they would help him find his granddaughter. They discovered she had become trapped in the colonists' "dream chambers", medical devices that put patients into a deep sleep and linked them in one communal dream. Inside the dream chamber, the Doctor's granddaughter met a human colonist named Jill, who promptly gave the young girl the name "Susan", after Jill's own mother.

Eventually, the newly named Doctor and Susan were reunited. They helped the colonists broker an uneasy peace with the foxes. They left the colony, deciding to retain the names they had gained there. The Doctor was deeply impressed by humans during this initial encounter. He told Susan they should find a way to settle amongst them for a while so that he could study them and they could maintain a low profile on the run from the Time Lords. (PROSE: Frayed)

In a different account, the Doctor and Susan's first destination was a vivarium beneath the surface of the Moon. Before walking outside, they were confronted by Quadrigger Stoyn, who had become an unwitting passenger and had part of his face burned when the TARDIS took off. Stoyn's job was to take apart the TARDIS' engines before it was sent to be vaporised, but the TARDIS had run out of power, stranding them. The Doctor took the dematerialisation circuit so Stoyn wouldn't leave them behind and they explored the strange location. The Doctor, Susan and Stoyn were taken out of the tank and realised they were in a massive cavern filled with vivariums carefully-preserved specimens. The Archaeons had been seeding primitive planets such as the Earth with life by firing red lightning from the Moon, creating an established order out of the chaos and nurturing the early life forms under controlled conditions.

While checking to see if the TARDIS was a threat, the Archaeons began taking it apart. They took the TARDIS' temporal stasis capacitor while it was still attached to the power source. This caused the stasis field to breach, freezing the Doctor, Susan, Stoyn and the Archaeons in time, allowing the TARDIS to recharge itself. 450 million years later, humans had evolved on the Earth until they established a lunar colony, Giant Leap Base. A group of humans from Giant Leap Base broke the stasis field, taking the Doctor and Susan on board their lunar rover, where they came to.

According to this account, the Doctor and Susan learnt about the Earth's history through a "first contact induction video" Susan had been provided while on board the rover. With the dematerialisation circuit still in the Doctor's possession, the Archaeons had sent nematodes, which didn't affect the Time Lords, to kill all of the humans on the rover. When the Archaeons, found the life they had "seeded" had become disorderly and "run rampant", no longer matching their carefully-planned vision, they "purged" the humans on the lunar base and on the Earth with lightning. The Doctor, who was blamed for the disruption of the Archaeons' experiments, was brought back to the cavern. Meanwhile, the humans retaliated against the Archaeons with missiles. After the Doctor went inside the TARDIS, evading the distracted Archaeons, Stoyn tried taking Susan with him, but she refused and ran inside the TARDIS.

With the dematerialisation circuit in place, the Doctor and Susan left without Stoyn, as the Doctor felt that he was just as willing to abandon them. Another barrage of missiles breached the atmosphere of the Archaeons' cavern, destroying their weaponry; the Archaeons were pulled outside, though Susan saw Stoyn struggle to reach the rover. Afterwards, the Doctor continuously watched the video about the Earth's history and evolution inside the TARDIS, marvelling at the planet's abundance. He promised it would be his next destination. Instead, his next stop was a place with a blue sun and air like wine. It took several trips before he reached the Earth again. (AUDIO: The Beginning)

Wanderers in the fourth dimension
Sometime after their first meeting with humans, the Doctor and Susan began to study Earth and humans more closely, with their first visit to Earth being a trip to the French Revolution (PROSE: Just War) in 1791. During this trip, the Doctor and Susan had several conversations with Robespierre's disguised agents, during which the Doctor used a multitude of English puns in his speech; when offered an egg sandwich, he said, "Something to draw me out of my shell, hmmm?" After some hours in Paris, the Doctor and Susan escaped from a Parisian military post using explosives from an artillery shell that had "accidentally" been left in a dark corner of the building. (PROSE: Christmas on a Rational Planet) Sometime after visiting the French Revolution, the Doctor met Iris Wildthyme, another renegade time traveller. (PROSE: The Scarlet Empress) Stealing her diary, he and Susan were "inspired". (PROSE: First Meetings)

The Doctor and Susan then went to ancient Rome, Mexico, Antioch, Jerusalem, and visited planets such as Mondas, (PROSE: Byzantium!) Dido, (TV: The Rescue) and Akhaten.

After being given an Ulster coat by Gilbert and Sullivan, (TV: "The Brink of Disaster") the Entity took the Doctor and tested him to open a door, but the Doctor outsmarted it. (AUDIO: Seven to One)

The Doctor accepted an invitation to be a guest speaker at a Time Conference on Refkeet Nine and raged against the local authorities when he discovered he had been lured into a trap so that they could use an abused Nuppino horse to attack him. He did not noticed his eleventh incarnation, who was watching him. (COMIC: Time Trick)

The Doctor and Susan arrived on an unnamed Jungle Planet, where they discovered a crashed colony spaceship with a row of graves, one of which was freshly dug. They then met Bethan, a salvage operative waiting for her partner Tino. After some searching, the group found Tino who had been reduced to a primitive state due to the planet's ecology. The Doctor and Susan after saying goodbye, quickly made their departure. (PROSE: The Arboreals)

The Doctor and Susan next visited Jabalhabad, India, in 1843, whilst they were touring India by elephant. They met Siger Holmes, father of Sherlock Holmes. (PROSE: All-Consuming Fire)

Visiting Earth again in 1979, the dematerialisation circuit was fried while the TARDIS was orbiting Earth. The TARDIS was taken on board a Slarvian transport, and the Doctor and Susan learned that the snail-like species planned to conquer Earth by hatching their eggs all over the planet. Their plan failed because the Slarvian ship crashed into the English Channel, making the threat localised to England. With the help of the humans Linda Grainger and her grandfather, Edward Grainger, the Doctor and Susan stopped the Slarvian eggs from hatching. (PROSE: Childhood Living)

After discovering the tyranny of a dictator, the Doctor travelled back in time to kill the dictator as a baby. However, whilst waiting in a queue, he accidentally dropped the silver knife he planned to use. Grumbling at his clumsiness, the Doctor left with Susan. (PROSE: Categorical Imperative)

Arriving at central Europe in the 16th century, Susan noticed what looked like a meteorite and tossed it out, thinking it unimportant, but soon came to realise that it was, in fact, a part of a Liciax ship. When she tried to find what she had carelessly discarded, it was gone. With the help of a man named Lovey, they traced it to Prague, where they found it had been shaped into a golem, that had developed sentience and was also on a murderous rampage. The Doctor and Susan trapped it in the attic of a Jewish synagogue, placing it under a security system, to which only they knew the access codes. (PROSE: Life from Lifelessness)

After landing in Germany in the sixteenth century, the Doctor and Susan teamed up with magistrate Rudolf von Slesinger and an inquisitor, Johann Eck, to protect Martin Luther from two assassins ahead of his trial. Instantly suspicious of Slesinger's odd behaviour, the Doctor sent Susan undercover as a servant girl and discovered that Slesinger had deployed the assassins in a plot to kill Luther in secret. Before he could kill anyone, Slesinger was apprehended by Eck. Afterwards, the Doctor and Susan decided to remain in Germany for the trial of Martin Luther. (PROSE: The Price of Conviction)

The Doctor encountered Alistair Gordon Lethbridge-Stewart at Christmas when he and his wife, Doris, saved Susan from drowning. The Doctor told Doris that he knew how his future friend would die and that he and his succeeding incarnations had already attended his funeral. (PROSE: The Gift)

The Doctor began pursuing the Soul Pirates after they stole his hand in a sword fight. Whilst following them, he and Susan arrived in 1900 London, where Susan and a group of children were kidnapped by the Soul Pirates to harvest their body parts for profit. However, the Doctor foiled their plan, rescued Susan and the children, and received a brand new hand, indistinguishable from the original, from Xing surgeon Aldridge. (PROSE: A Big Hand for the Doctor)

Vacationing at a bed and breakfast called "Bide-a-Wee" in the British coastal town of Keelmouth in 1933, the Doctor discovered that another guest was a time traveller, named Prentice. He had used his technology to displace Keelmouth in time; the village was in 1933, but the surrounding world was in 1999. The Doctor and Susan had to convince Prentice to reverse the effect, because his retirement fantasy wasn't fair to the people he had trapped alongside him. (PROSE: Bide-a-Wee)

Not long after, the Doctor and Susan accidentally landed at the BBC's Paris studios in 1955, because transmissions there had disabled their dematerialisation circuit. They met a radio comedian named Max Wheeler, whose recordings were plagued by a distinctive background "hum" caused by ghostly aliens known as the Shakers, aliens recruited into the French resistance in World War II, unaware that the war had ended and unable to clearly understand who their enemies were. Though he and Susan tried to explain the current reality to them, the Shakers continued to kill indiscriminately, with the only course of action left being for the Doctor to alter the harmonics of canned laughter and kill them with it. (PROSE: Losing the Audience)

When the Doctor was forced to land his malfunctioning TARDIS on Earth to repair it, Susan left to explore the area. After a while, the Doctor began to worry and set out to look for her - a search that brought him face to face with the Cybermen. (PROSE: Dr. First)

The Doctor and Susan travelled to Bridgetown on the planet Quinnis in the fourth universe. They nearly lost the TARDIS when it was washed away during a severe flood. They recovered it with the assistance of a huntsman named Evalihi Parch IV, who possessed an ornithopter. (AUDIO: Quinnis) Whilst on Quinnis, the Doctor was trained to be a ninja. (PROSE: The Devil Goblins from Neptune)

The Doctor and Susan unwittingly travelled to Paris in the 22nd century, where they became embroiled in political intrigue in the run-up to an election in the city of Urrozdinee. (PROSE: Urrozdinee)

At this point, the Doctor realised that he and Susan had been losing their memory since they began travelling in the TARDIS due to the telepathic circuits attacking their minds. This prompted their search for somewhere to take residence and recover from the memory loss. (PROSE: Echoes of Future Past) Their loss of memory would stay for some time after settling in London. (PROSE: Time and Relative)

The Doctor and Susan went to Berlin in January 1933. There he met Fitz Haber and planned to help him with his studies. When Pollitt drugged Susan, he became aware that something dangerous was going on and that they should try to leave the place. (AUDIO: The Alchemists)

The Doctor took a brief trip to St Albans on 17 December 1997 to ensure that the United Kingdom would remain safe during the 1960s and had a near-miss encounter with the Fourth Doctor, Romana II and K9. (PROSE: The Little Things)

Hiding on Earth
Making a short trip to the planet Tacunda, the Doctor and Susan uncovered a "Blessing Star", a crystal that altered the laws of probability around the holder, essentially making their dreams come true. The Doctor tried the device, wishing that he could pilot the TARDIS to 20th century Earth. He was successful at piloting the ship, unfortunately, it completely fried the navigational system, stranding the Doctor and Susan in I.M. Foreman's junkyard in Totter's Lane, London in 1963. (PROSE: The Rag & Bone Man's Story)

The Doctor and Susan took up residence in a Totter's Lane junkyard in Shoreditch, London to allow Susan to complete her education, and so the Doctor could effect repairs and build missing components for the TARDIS. According to this account, Susan's admission to Coal Hill School was in late March. (PROSE: Time and Relative) According to another account, Susan and the Doctor arrived in Shoreditch in June 1963. (AUDIO: Hunters of Earth) While the Third Doctor claimed that Susan gave herself the surname "Foreman" from I.M. Foreman, (PROSE: Interference - Book Two) Susan recalled that it was the Doctor who gave her the surname "Foreman". (PROSE: Legacy of the Daleks) After arriving in 20th century England, the Doctor spent months stealing parts to repair his TARDIS. (AUDIO: Hunters of Earth)

Although he was known to be unsociable and unlikely to travel outward, this did not stop his search for knowledge. He at least once visited a library, (TV: The Vampires of Venice) was familiar with the owner of the local café, (TV: Remembrance of the Daleks) and spent many "happy hours" taking the Hand of Omega for "walks". (PROSE: Alien Bodies) The Doctor first encountered River Song when he caught her sneaking around the junkyard where his TARDIS was located, but he was unaware of her identity. River fled when she heard Susan calling her grandfather. (GAME: The Eternity Clock)

In April 1963, while Susan was attending Coal Hill School, London was consumed by winter weather in the middle of spring, as a result of an extra-dimensional called the Cold awakening. After being coerced by Susan, the Doctor reluctantly decided to interfere in events, and defeated the Cold by depositing it on Pluto in the far future, before it destroyed all humanity on Earth. (PROSE: Time and Relative)

Trying to return to Susan after leaving the Cold on Pluto, (PROSE: Time and Relative) the Doctor arrived on Wengrol in the Crab Nebula, the furthest the TARDIS had ever travelled at that point. He was captured by Yend scientists looking for a way to stabilise their constant shapeshifting. Fomal, the Chief Yend, asked him to take a case of unmutated Yend embryos to a new system, but when the Doctor took the case into the TARDIS, he discovered that the embryos were all dead. (PROSE: The Sons of the Crab)

Landing on Vortis, the Doctor was captured by the Menoptera, who believed that he was a member of the race attacking them. He escaped, only to encounter a group of Atlanteans whose spacecraft had crashed on Vortis a year earlier. The Atlanteans mistook the Doctor for a Human scientist and asked for his help in repairing their ship. The Doctor, claiming that the necessary parts were in his ship, returned to the TARDIS, where he watched as the Atlanteans were caught in a battle between the Menoptera and the Zarbi and killed. (PROSE: The Lost Ones)

The Doctor landed on Earth in 1966. While leaving the TARDIS unattended, two children, Tony and Amy Barker, and their dog, Butch, entered the ship and accidentally locked themselves inside. When the Doctor returned, he dematerialised the TARDIS and arrived on the Sense Sphere, where he was forced to kill a Zilgan to save his life. The Sensorites captured him and planned to execute him for his crime, but he was rescued by Tony and Amy. The three made their way back to the TARDIS and the Doctor returned the children to their own time. (PROSE: The Monsters from Earth)

Out for a walk, while thinking of where to hide the Hand of Omega, the Doctor's seventh incarnation appeared in his past self's life on a mission from the White Guardian to steal the TARDIS Instruction Manual. Unbeknownst to the First Doctor, the Seventh Doctor saved him from an Imperial Dalek and made off with the instruction manual in the confusion. (COMIC: Time & Time Again) By October 1963, the Doctor had hidden the Hand of Omega at an undertaker's. (TV: Remembrance of the Daleks)

After killing a werewolf with a silver bullet in 1960s London, the Doctor was placed on trial for murder. He was acquitted by the jury which was made up partly of his second, third, fifth and eighth incarnations. (PROSE: The Juror's Story)

After the Doctor and Susan got lost at night in the dense fog, they met a girl named Joan Calder and sheltered at her home, where they met her mother and grandfather. During the visit, the house burst into flames and, on the Doctor's instruction, Susan broke a mirror in the house. The elder Calder crumbled into ash and the fire abated. Although the Doctor never was able to adequately explain the event, it was related to the fact that the house had in fact been leveled during the London Blitz two decades earlier. The Doctor postulated that Susan's action likely saved the lives of Joan and her mother. (PROSE: Ash)

After witnessing a man explode into a protoplasmic mass at a beat poetry reading, the Doctor and Susan traced the unusual death to a British government project, Operation Proteus. They discovered the project was being run by an alien named Raldonn, who was mutating humans to turn one into his own species so that he would have a co-pilot to help him fly his ship back home. Unfortunately, his efforts relied on a lethal virus that threatened all London. After reversing the effects of the virus, the Doctor and Susan returned to the TARDIS in Totter's Lane. (COMIC: Operation Proteus)

In October, the Doctor decided to collect parts to repair the TARDIS legally. He saw an advertisement for Magpie Electricals, and gave his billing address to Bernie at the shop, who handed the Doctor a card of the address of the warehouse to pick up the parts the following Tuesday. On the way back home, he was threatened by a group of teenagers, before they stopped and apologised. When the Doctor arrived at the warehouse, Colonel Rook revealed that he had tricked the Doctor into coming here by placing the advertisement in the paper. Rook wanted the Doctor to fight in a war and Susan to help in Britain's ESP experiments. When Susan and Cedric arrived after being chased by gangs chanting "aliens out", the Doctor deduced they were being influenced by a hypersonic weapon transmitted over radio waves that made young people attack anyone who was "alien", or different, including the Doctor and Susan. The Doctor devised a means of using Susan's radio and other pieces in the warehouse to transmit a blocking signal that negated the effect of the weapon. After his life was saved, Rook decided against coercing the Doctor and Susan to fight in the war and told them that their "secret" would be safe. Afterwards, Susan received a premonition of something coming for the Doctor in his future that he couldn't escape. (AUDIO: Hunters of Earth)

The Doctor began investigating an alien insect and planned to take it home. His quick retreat from the 1960s prevented him from doing so. He wouldn't deal with the insect until he was in his fourth incarnation. (PROSE: Those Left Behind)

Meeting Ian and Barbara
Returning to the junkyard to find that two of Susan's teachers, Ian Chesterton and Barbara Wright, had followed her home, the Doctor tried to encourage them to leave, but they confronted him and forced themselves into the TARDIS. Against Susan's wishes, he launched the TARDIS, kidnapping them so they couldn't tell anyone about them. They travelled to prehistoric times. Kidnapped by a tribesman named Kal, the Doctor was brought to the Tribe of Gum. Susan, Ian and Barbara followed to save him, but Za caught them and placed them all in the Cave of Skulls.

The group was freed by Old Mother, to which the Doctor thanked her, but he grew miserable whilst trekking through the Forest of Fear. When a pursuing Za was wounded by a tiger, the Doctor initially refused to help him. He picked up a rock and was prepared to kill Za, until Ian stopped him, (TV: An Unearthly Child) and a meeting with his eighth incarnation in a time bubble convinced him not to. (PROSE: The Eight Doctors) Recaptured and placed back in the cave, the Doctor tricked Kal into revealing he had killed the Old Mother. The Doctor helped Ian with an escape plan, and the travellers made it back to the TARDIS. (TV: An Unearthly Child)

When the TARDIS landed on Skaro, the Doctor claimed that the fluid link needed more mercury, despite there being nothing wrong, so that he could explore a nearby city despite his companion' concerns, even that of Susan herself. The Doctor had planned to explore the city a day after their arrival, but a knock from one of the Thals on the door frightened the other travellers, and they forced the Doctor to take off. The Doctor, still desiring to see the city, removed the fluid link and caused the TARDIS to stall and claim the fluid link's mercury had run out, and that the only likely place to find more was the city itself. In the city, the Doctor and his friends were captured by the Daleks, confiscating the fluid link they brought along.

Having escaped, they assisted the Dalek's enemy, the Thals, in their attack on the Dalek city. The Daleks' power supply was damaged in the attack. The Daleks died and their plans to flood the atmosphere with radiation failed. (TV: The Daleks) However, the Doctor had seen the evil of the Daleks and made it his mission in life to combat threats similar to them. (TV: Into the Dalek)

With the fluid link retrieved, the Doctor left Skaro for Earth, using the fast return switch. The spring in the switch was damaged, causing it to be stuck. The TARDIS was sent to the beginning of a solar system and everyone was knocked out on the trip. The TARDIS tried warning the crew about the atoms forming around them when they came to, but the Doctor assumed that this was Ian and Barbara sabotaging the ship. Once Barbara figured out what was going on, the Doctor fixed the spring and apologised to his human companions, ending the fault. (TV: The Edge of Destruction) After this incident, the Doctor's relationship with Barbara and Ian became warmer, and he began to learn about and respect their humanity. (COMIC: Hunters of the Burning Stone)

The great spirit of adventure
Still heavily damaged and malfunctioning, the TARDIS found its way to Earth but did not make it to Ian and Barbara's time. Instead, it landed in the Plain of Pamir in 1289. There, the Doctor and his companions met Marco Polo. Polo took the TARDIS and its keys on his caravan to the breadth of Cathay to hand to Kublai Khan as part of a bargain for his return to Venice. Along the way, the Mongol warlord, Tegana, also part of Polo's caravan, tried to take the TARDIS for Nogai as part of his plan to assassinate Kublai. In the chaos of Tegana and Polo's duel in Peking, the Doctor and his companions escaped in the repaired TARDIS. (TV: Marco Polo)

He landed on the Spaceship Vanguard and was concerned when a war ship contacted it. Upon examining the Vanguard he noticed that there were stress marks relating to explosive decompression. He was asked to create a radiation filter so they could go after Barbara. He discovered that Myla had manipulated the evolution of the Shifts to get more bodies. The section of the ship which he was in went missing. He worked out that there was a pressure resistant cabin in which he and Olivan survived. He managed to create a device that would confuse the Shifts. He tried to convince Arran that there was another way. (AUDIO: The Age of Endurance)

Finding themselves in what appeared to be an English forest, the TARDIS crew soon learned that the situation was more complex than it appeared when they discovered a medieval camp, a crashed spaceship, and were attacked by a dragon before being rescued by a knight. Taken to a nearby castle, they learned of a current conflict against the sorcerer Marton Dhal, who sought further power by acquiring Merlin's old artefacts, the Doctor naturally puzzled at the existence of what appeared to be magic. Participating in a quest to gain Merlin's Helm, the Doctor and Ian learned that the 'magic' was the result of a complex nanobot network that allowed those skilled in its use to manipulate the world around them. With tutoring from the leprechaun Kilvenny Odoyle, the Doctor was able to learn how to use the world's magic himself, joining Odoyle and witch Anni Glassfeather in a final duel against Gramling, Dahl's former master, who had manipulated Dahl in the name of his own dreams of power. With Dahl defeated, the Doctor was able to arrange for the nanobot network to be disabled, leaving the people to learn how to cope without magic. (PROSE: The Sorcerer's Apprentice)

The Doctor arrived in Greenland in 1002 due to a leak in the TARDIS' plutonium battery. He enlisted the aid of Eric the Red and his Viking crew to take him and his companions to Newfoundland to get the materials he needed for his ship. They were nearly left behind in Nova Scotia, but the Doctor convinced the Vikings to take them back. (PROSE: Who Discovered America?)

The TARDIS landed on an island on Marinus, where Arbitan asked the Doctor and his friends to search for the keys to the reprogrammed Conscience of Marinus to regain control over the Voord, as all of his other followers and family members failed to retrieve them. When the Doctor refused his aid, Arbitan trapped the TARDIS in a forcefield, preventing the Doctor and his companions' escape. They used Arbitan's travel dials to reach Morphoton. Barbara released Arbitan's daughter, Sabetha, and the rest of the city from the Morpho's mind control, and retrieved the first key.

The Doctor jumped ahead to Millennius, the location of the final key, to find Eprin. Once Ian had found two more keys, he was knocked out and framed for Eprin's murder. The Doctor stood as defence at Ian's trial, but Ian was sentenced to death. The Doctor learnt that one of the conspirators in the murder, the prosecutor, Eyesen, was ready to collect one of the keys and Ian was spared execution. The guards captured Eyesen and the last key was found in the mace that killed Eprin.

The Doctor and his companions returned to Arbitan's island, where Arbitan had been murdered. Ian handed the Voord leader Yartek a fake key, which destroyed the Conscience, along with the Voord. They were able to leave in the TARDIS once more. (TV: The Keys of Marinus)

Arriving inside the tomb of Menkaure in Egypt in 26th century BC, the Doctor, Susan, Ian and Barbara were arrested and taken to the palace. Itennu planned to assassinate Pharaoh Menkaure with a poison dart and then blame the strangers. However, the Doctor inadvertently foiled the attempt with his walking stick and, when a more open attack began, the travellers fled back to the TARDIS, once again barely escaping with their lives. (COMIC: The Forgotten)

The Doctor and his companions arrived in an Aztec temple in Mexico. They went through a one-way passage that prevented access to the TARDIS. Barbara posed as the Aztec god, Yetaxa, with the others as her servants, to find a way back. Barbara tried and failed to change the Aztecs' history of human sacrifice for the better, which the Doctor strongly advised her against. Susan was to be punished for denying marriage to the Perfect Victim of the Aztecs' sacrifice and Ian to be executed when he was framed by the High Priest of Sacrifice, Tlotoxl, for attacking the High Priest of Knowledge, Autloc. Autloc's faith in Yetaxa was shattered, and he left for the wilderness. The Doctor and Ian distracted Ian and Susan's guard to escape. They worked on a pulley system to open the doorway back to the TARDIS. As they departed, the sacrifice of the Perfect Victim continued as planned. (TV: The Aztecs)

The Doctor and his friends next arrived inside a spaceship in the 28th century, where two crewmembers were suspended in a state resembling death and another, John, had had his mind opened and turned insane, following an attack on their minds by the Sensorites. The Sense Sphere, which the ship had been trapped around, had its aqueducts' water supply poisoned with atropine by survivors of a previous human expedition whose ship had been destroyed.

The TARDIS' lock was taken by the Sensorites, leaving the Doctor and his companions trapped on the spaceship. After the Doctor and his companions resisted the Sensorites, the Doctor, Ian and Susan agreed to go down to the Sense Sphere, where the Doctor worked out the cure for this "disease", which had also afflicted Ian, while the Sensorite scientists treated John.

The Doctor and Ian, followed by Barbara, went to the aqueducts where Atropa belladonna had been growing. They found the human expedition and pretended to be a welcoming party for them and that the "war" against the Sensorites was won. The expedition was taken into custody on Maitland's ship. Maitland's ship was free to leave and the TARDIS crew had regained their lock. (TV: The Sensorites)

Although he lost his key to the TARDIS during a fight in the camp, the Doctor was able to tell his story to Captain Benadik Lant, who passed it on to Mayor Brantus Draad, who asked the Doctor to help them complete work on the ship that would take the survivors to Mirath in exchange for the facilities to build a new key. During his time working on the Ship, the Doctor realised that it was a monstrous deception, but despite being distracted by the twisted actions of Monitor, the city's supervisory A.I., who had created android duplicates of Susan and several others, the Doctor was able to help the citizens of Arkhaven leave their dying world in a landing module that had been 'upgraded' with a life capsule from the TARDIS, giving the ship more interior space without increasing its mass.

There he encountered Bret Vyon, a Space Security Agent who wanted to steal the Doctor's ship. He knocked him out and took his keys, entering the ship and demanding that Katarina pilot it. Steven soon woke up and, seeing the Doctor looking angry on the scanner, knocked Bret out and let the Doctor in. After securing Bret to a chair, the Doctor soon went outside again, where he heard a spaceship landing, and decided to head towards it in search of the needed medicine, only to learn to his horror that it was actually a ship belonging to the Daleks. After moving away from the Daleks unseen the Doctor discovered a magnetic tape in the jungle undergrowth. He rejoined his friends who escaped from the TARDIS with Bret's help. Bret however brought bad news, the Daleks have started to burn down the jungle. With the Doctor resolved to find out what the Daleks are doing here and stop them, he and the others discovered a large landing bay with ships from the many outer galaxies and a Spar ship Bret recognised as belonging to Mavic Chen, the Guardian of the Solar System. After capturing one of the delegates, Zephon, the Doctor used his cloak as a disguise and infiltrated the meeting. There Mavic Chen presented the Daleks with the Taranium Core, the power source for the Daleks' deadly weapon, the Time Destructor. However, the Doctor stole the Taranium and ran off before the meeting was concluded.

He only just managed to get aboard Chen's Spar in time before Bret and the others blasted off, stealing it in the process.

With Steven and Bret having fixed the Spar and the Doctor having used his ingenuity to prevent some prisoners getting on board, the ship took off again with everyone relieved to have gotten away. However, another prisoner, Kirksen, had snuck on board and took Katarina hostage inside the airlock. Despite Steven and the Doctor's protests, Bret was forced to turn the ship back towards Kembel. But before he could do this, without warning, Katarina opened the outer door of the ship, sending her and Kirksen out into the vacuum of space and to their deaths. Shaken, the Doctor lamented that, while Katarina couldn't have understood what she was doing, he would always remember her as one of the daughter's of the gods. After landing on Earth they went to see Daxtar, a friend of Bret's who he thought would believe their story, at a nearby research complex. Daxtar proved to be untrustworthy when he let slip he knew about the Taranium. Suspecting him to be in league with Chen, Bret shot Daxtar dead. Believing they would be caught any moment, the Doctor and Steven escaped just as another SSS Agent, Sara Kingdom, arrived. Showing no mercy, she killed Bret before he had a chance to explain himself.

Running through the complex, the Doctor and Steven discovered a large, empty chamber with only a glass container of white mice inside. Sara caught up with them before the whole room became fuzzy and they began to scream in agony. The Doctor finally came to his senses on the swampy planet Mira. He reasoned that he and the others were part of a molecular dissemination experiment and had been transmitted to this far-off planet. The Daleks had also arrived on Mira with a small task force to apprehend the travellers and regain the Taranium. After the Doctor found Steven and Sara again they made their way to a nearby cave for shelter and tried to persuade Sara about the Daleks' plot with Mavic Chen. Steven was also furious with Sara for killing Bret in cold blood. Reacting to this provocation, Sara admitted that Bret Vyon was her brother. Suddenly the invisible inhabitants of Mira, the Visians, surrounded the cave but a Dalek appeared and shot one of them dead. Luckily the other Visians began to attack the Daleks and in the confusion, the travellers evaded capture, stole the Daleks' spaceship and escape Mira. Upon their return to Kembel, the Doctor gave the Daleks a copy of the Taranium Core he had made on the way, then returned to the TARDIS.

The Doctor landed outside a police station on 25 December 1965, where he was arrested. After being rescued by Steven, they visited a Hollywood film studio in the 1920s, though they did not know where they had landed and thought they were in an insane asylum. The Doctor was mistaken for an expert on Arab customs and had an encounter with Bing Crosby. Back on board the TARDIS, the time travellers toasted a Happy Christmas to themselves. (TV: The Daleks' Master Plan)

Shortly after celebrating Christmas, the Doctor found that the TARDIS was locked onto the signal of another time machine, which was travelling to several different Christmases throughout Earth's history. Eventually, Sara realised that the other time machine belonged to Robert, who had become trapped in the machine after the death of his twin brother Christopher and unintentionally trapped it in a loop where it would perpetually visit different Christmases trying to fulfil Robert's wish to go back to before his brother died of leukaemia. When the now-adult Robert touched the taranium core and reverted to his original age, the Doctor used the unique circumstances of the current situation to subtly change history, using the Fast return switch to take Robert back to the last Christmas so that he could take the place of his brother, the TARDIS crew then taking Christopher to Mars so that he could see something incredible before his death. (PROSE: The Little Drummer Boy)

Resuming their travels, the TARDIS collided with another ship. They landed on a desert island with the crew of the other ship. He discovered that the ship was an experimental time ship which was going to be used in a war. Later he encountered a Time Sprite which he thought shouldn't exist. The island was created as a form of recuperation from the TARDIS emergency systems. (AUDIO: The Anachronauts)

While dreaming, the Doctor travelled to the Underworld to guide Katarina through it. (PROSE: Katarina in the Underworld)

On their travels, they landed on a planet covered in water, where they found a set of miners in a collapsed mine. Here they were attacked by a tentacled creature, but Sara and the Doctor were able to reason with it. (AUDIO: The Drowned World)

When they visited the Great Clock, the Doctor thought he was being dragged there. He was intrigued by the working of the clock. He discovered that the clock was powered by prisoners and decided to sabotage it, which also saved Sara from her tentative earlier efforts to betray the Doctor and change history, Sara realising in time that her actions had actually become part of her past rather than changing it. (AUDIO: The Guardian of the Solar System)

The Doctor, Steven and Sara then landed in Ely in a house which had a secret. He theorised that the house could sense what you desired. Exploring the house they found dead bodies. He wanted to investigate but Steven got annoyed when he couldn't find a way to get out of the house. (AUDIO: Home Truths)

They later landed in London in the 1950s, when they were ejected from the TARDIS with the Doctor unconscious. He later went missing with the TARDIS for a couple of weeks, until Steven found him in the Docks where the Anemone changeling had taken him. He managed to escape after Steven found him and he managed to find Sara. He went with Sara to a pub where he noticed that the changelings where near him by the fact that people from different races were integrating. He had to stay at the pub with Audrey Newman's baby as he couldn't move. (AUDIO: An Ordinary Life)

Attempting to rest on a moon-sized asteroid on a figure-of-eight asteroid belt between two gas giants, the TARDIS crew were caught in a conflict between members of the Space Security Services and a Sontaran platoon, the SSS forces seeking to take control of a Sontaran space cannon that would allow them to destroy any human ships passing through the only safe path through the asteroid belt. This crisis was made more complicated as Sara knew of this event from history. Despite the Sontarans infiltrating the SSS team using a stolen Rutan device to transform one of their own into a human, as well as the Sontarans managing to capture and interrogate Steven after a cave-in separated him from the rest of the team, the TARDIS crew and the SSS team leader were able to reach the cannon and destroy it with the aid of the asteroid’s native population. Although the cannon was no longer a threat, Sara’s knowledge of the future revealed that the asteroid would be found deserted around a year from then, suggesting that the Sontarans would kill them in revenge for this action, although the natives decided to hope for the best. With this example in mind, the Doctor, Steven and Sara decided that it was time to return to the battle with the Daleks. (AUDIO: The Sontarans)

The Doctor discovered that another time machine was on the same flight path as their own, and thought it might be the Daleks pursuing them. After briefly materialising in the Oval during a cricket match, they landed on Tigus, where the Monk, having escaped being stranded in 1066 and seeking revenge, sabotaged the TARDIS lock, stranding the Doctor and his companions. However, the Doctor quickly fixed the problem and departed, the Monk following close behind.

After briefly materialising in Trafalgar Square immediately after midnight on 1 January 1966, during New Year's Eve celebrations, they landed in ancient Egypt near a pyramid. Not only was the Monk there, but so were the Daleks, who had discovered that their Taranium Core was a fake. After stealing the directional unit from the Monk's TARDIS and changing its shape to a police box, the Doctor was forced to hand over the real Taranium Core to the Daleks, who had taken Steven and Sara hostage. The Doctor used the directional unit to take the TARDIS back to Kembel. The Doctor activated the Daleks' Time Destructor, which destroyed them, transformed Kembel into a desert, and rapidly aged Sara to death. The Doctor regretted the losses of Bret, Katarina and Sara. (TV: The Daleks' Master Plan)

Oliver Harper
When the TARDIS materialised in 1966 London, the Doctor and Steven encountered the Fulgurites, who were involved in the trafficking of humans across the galaxy for slave labour with the full knowledge of the British government. The duo put an end to the Fulgurites' activities with the assistance of a young homosexual city trader named Oliver Harper, who joined them in the TARDIS to escape being arrested for his sexuality. (AUDIO: The Perpetual Bond)

The Doctor took Steven and Oliver to a satellite which was near a meteor field, but the Calleons chucked the TARDIS off the satellite when they saw no value in it, annoying the Doctor. However, when a girl entered the TARDIS, he realised that she had accidentally caused the satellite to fall out of orbit, resulting in the satellite being fractured when it struck a piece of space debris, the Doctor and the Calleons in one part of the satellite while Oliver and Steven were in another. After Steven was able to perform some complex flight calculations to nudge his fragment back to the Doctor's, the Doctor worked with Oliver and the Calleons to draw up new contracts that would help the humans benefit from the Calleons' work while Steven recovered. (AUDIO: The Cold Equations)

The Doctor didn't want to change history and took Oliver and Steven to Grace Alone, as he found their names on criminal records on a database in the future. He tried to hide his thoughts from the Vardans to stop them from learning knowledge about the TARDIS, going so far as to fake his death and trick his companions so that he could take the Vardans by surprise later. Oliver would later meet his death at the hands of the Vardans while saving his friends' lives, disrupting the last Vardan in a final attack. (AUDIO: The First Wave)

The Game of Rassilon
While he tried to look for ways of rectifying his relationship with Steven by visiting a rose garden for some peace and contemplation, (PROSE: Roses) the Doctor was taken by the Time scoop to the Death Zone, where he was briefly reunited with Susan. While there, he defeated a Dalek by trapping it in a narrow corridor, where its own weapons fire ricocheted back at itself, destroying it. He was reunited with his second and third incarnations, and met his fifth incarnation, Tegan Jovanka and Vislor Turlough. He also briefly met a future incarnation of, though didn't recognise him. He was the only one of the four incarnations of the Doctor present who realised the true meaning of the inscriptions related to the immortality offered by Rassilon and triggered the events leading to Borusa's eternal imprisonment within a sarcophagus. (TV: The Five Doctors)

Time alone
After returning Susan to her new home, the Doctor began travelling on his own with the ability to pilot the TARDIS effectively, as a favour granted to him by Rassilon as he was approaching his first regeneration, allowing him to tie up some of the loose ends he had left. He took this opportunity to show Rebecca Nurse how her death would be perceived in the future (PROSE: The Witch Hunters) and perform the prologue for William Shakespeare's Troilus and Cressida. (PROSE: Troilus and Cressida)

Along with seven of his other incarnations, the First 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 Vortis again, at a time in which the Zarbi Supremo had moved the planet to the solar system. With the aid of Gordon Hamilton, he freed the crew of the Solar Queen from the Supremo's control, allowing them to turn on and kill the Zarbi leader. (PROSE: The Lair of Zarbi Supremo)

After an incident with the Daleks on Skaro, the Doctor landed on Mechanistria and met the Korad named Drako.

He attempted to sabotage their ship but was overpowered by the Voord, who launched him into space, although he was saved by the Daleks. He was able to warn the Earth of the fleet and told the Voord of the Daleks' plan to destroy them once finding the Great Power. The Voord and the Daleks began fighting again in Earth's atmosphere, as the Doctor landed in South America in an escape pod.

In the pod, he was attacked by the Chief Voord but gained his trust after saving his life. The two then learned that the Great Power was a mushroom whose juice would expand minds to exponential amounts. The Daleks were looking for the mushroom in the wilderness, and the pair hatched a scheme for the Chief Voord to lead them to the mushrooms. At first, the Daleks grew extremely intelligent due to the juice, but they all soon perished due to its poisonous nature. (PROSE: Doctor Who and the Daleks)

They arrived on a spacecraft leading an Andromedan armada, where they encountered androids called Aalas and met the One, the intelligence controlling the ship. When the Doctor refused to help the One invade the Milky Way, this disobedience caused it to malfunction, and it self-destructed when Ida threw a bowl at one of its screens. The Doctor and the Mortimers departed, leaving the armada drifting aimlessly in space. (PROSE: Doctor Who and the Invasion from Space)

Resumed travels with Steven
The Doctor arrived in Paris in 1572, where he decided to visit Charles Preslin, leaving Steven to sightsee. After reuniting with Steven, the Doctor realised that the St Bartholomew's Day massacre was about to begin and departed in the TARDIS. Steven was very angry that the Doctor had left Anne Chaplet, the French girl he had befriended, to her probable death, and disregarded the Doctor's plea that he couldn't rewrite history. He departed the TARDIS when it landed in Wimbledon Common in 1966, leaving the Doctor alone to reminisce over all of the companions who had left him. He briefly wondered if he should return to his own planet, but decided that he could not. However, Steven returned when a young girl named Dodo Chaplet forced her way into the TARDIS, which then departed. (TV: The Massacre)

Steven and Dodo
The TARDIS took them to New York, where a cult had formed around six self-proclaimed "gods", who performed miracles on their followers. The Doctor's suspicion proved true when the gods turned out to be alien lifeforms, who existed by belief and gained power equal to the faith the humans held in them. Recognising the danger such creatures posed, the Doctor worked with the US military to weaken the faith of the gods' worshippers, subsequently driving the gods away by dropping a dud bomb that everyone watching believed would harm the gods. The Doctor and Steven subsequently accepted their differences and departed in the TARDIS, taking Dodo as their new companion. (PROSE: Salvation)

(AUDIO: The War to End All Wars)

The Doctor, Steven and Dodo arrived on a planet shared by two very different peoples, the Elders and the Savages. The Elders led a very civilised lifestyle, but their intelligence was gained by draining the life energy from the Savages.

The Doctor invited Carvossa to join them, but she ran away in terror upon seeing the inside of the TARDIS. (AUDIO: The Yes Men)

The TARDIS landed in what appeared to be Paris just after the French Revolution, but history had been perversely warped. Dodo and the Doctor became separated, with Dodo being taken in by a travelling troupe of actors, and the Doctor being held prisoner in the Bastille. They discovered that the history in which they had landed was an altered history, made by aliens whose curiosity made them rewrite history to the designs of a depressed Marquis de Sade. After correcting history, Dodo and the Doctor left the alternate France behind. (PROSE: The Man in the Velvet Mask)

Soon after, the Doctor faced the mad computer WOTAN and its War Machines in London on 20 July 1966. After, he was forced to leave an injured Dodo on Earth. (TV: The War Machines)

Alone again
The Doctor met Winston Churchill in 1911 when he stepped out of the TARDIS. The Doctor told Churchill it was an honour to meet him, but was informed that they had met before, with the Doctor chuckling about this being "the trouble with time travel". (PROSE: The Lost Diaries of Winston Spencer Churchill)

While travelling alone, the Doctor was found by the Time Lords, and placed into a "celestial retirement", during which he was scolded for meddling in history during his visit to Paris in August 1572. (PROSE: The Massacre)

After his retirement ended, the Doctor shared a couple of glasses of Medoc with John Lucarotti at the Auberge du Pont Romain, and suggested that Lucarotti have a vacation to Samarkand. (PROSE: The Meeting)

Nearing the end
After he inadvertently picked up Polly Wright and Ben Jackson as companions when they entered the TARDIS as it took off, (TV: The War Machines) the Doctor and his new friends got caught up with a band of smugglers led by Captain Samuel Pike as he searched for a lost treasure. Although the Doctor was forced to help Pike trace a series of clues to the location of the treasure in a local graveyard, the smugglers were eventually captured by the local revenue men and Pike was killed.

After they left in the TARDIS, the Doctor assumed that they had landed "at the coldest place on Earth", (TV: The Smugglers) but it was soon revealed that they had actually landed in Lewes in the 1950s, where they became caught up in a series of local riots. (AUDIO: The Bonfires of the Vanities) When Ben and Polly first went exploring in the TARDIS, the Doctor found himself coming to their rescue when they got lost. (PROSE: Something at the Door)

The Doctor, Ben and Polly arrived in New York City in the 1890s where four Ovids had become trapped. Their presence caused people's dreams and nightmares to manifest in reality. The time travellers were able to free the Ovids with the assistance of Harry Houdini. (AUDIO: Smoke and Mirrors) They also visited an uninhabited planet, where the Doctor collected some plants and rocks. (PROSE: Doctor Who and the Tenth Planet)

Attempting to take Ben and Polly to the coronation of Queen Victoria, the Doctor landed on Mars instead. They set up a camp and a tent and began roasting marshmallows. However, a fault with the TARDIS forced them to leave in a hurry before the time machine took off without them. The tent and the Doctor's pipe were among the items left behind. (PROSE: Please Shut the Gate)

During a confrontation with the Schirr terrorists known as the Ten-Strong, the Doctor put himself under great strain to hold back a paralysing pulse capable of immobilising eight people with his own mind. He was able to disrupt the cyber-telepathic link the Ten-Strong were trying to use by making contact with the consciousness of Shel, an android who had been physically destroyed earlier but whose consciousness remained active in the network. As he and his companions departed, the Doctor began to reflect that he would soon feel a whole new person. (PROSE: Ten Little Aliens)

While his companions were sleeping in the TARDIS, the Doctor met Professor Chronotis at Cambridge University. (PROSE: Cambridge Previsited)

While dealing with a telepathic plague in the sixteenth century, the Doctor and his companions were assisted in curing the plague by another Time Lord, the Player. Once the initial virus had been dealt with, the Doctor had Polly confront the Player about his presence, and the Player explained that a force from the future had been interfering with the Doctor's timeline to prevent his regeneration into an incarnation who would be needed in a great conflict. Although the Player revealed that the Doctor would not become this incarnation for some time, the Doctor accepted the need to fulfill his destiny and return to the South Pole so that history could unfold as it should. (AUDIO: The Plague of Dreams)

Before Antarctica, the TARDIS fell out of the vortex, caught in the descent of an Angel falling through reality. Landing on an unnamed planet, the Doctor, Ben, and Polly spoke to the Angel, who told them all beings were always falling and to let go. When the Angel faded away, the time travellers departed. (AUDIO: Falling)

Suffering from nightmares about his father, the Doctor awoke to find the TARDIS had been drawn to Gallifrey on the night he absconded with Susan. Roaming the deserted mountains, he encountered his old mentor, K'anpo Rimpoche, and was offered a chance to return to his life on Gallifrey before his departure, which would rewrite his own past and erasing his travels in time and space. Resisting temptation, the Doctor ran from Gallifrey once again, aware that his next destination would be his last. (PROSE: The Three Paths)

Last stand
With his ancient body wearing thin, the Doctor, Ben and Polly arrived at the Snowcap base in 1986 Antarctica, where they were treated with hostility by General Cutler. When the pilots of Zeus IV discovered a new planet between Mars and Venus, the Doctor, having predicted this, tried to convince the crew that Earth had a twin planet millions of years ago called Mondas, but Cutler refused to listen and sent his men to claim the TARDIS. However, the station came under attack from the Cybermen, and the Doctor collapsed when Mondas began draining Earth's energies, (TV: The Tenth Planet) due to his regeneration process starting. (PROSE: Interference - Book Two)

While unconscious during the crisis at Snowcap base, the Doctor was contacted by Steven and arrived to help stop the Vardan woman from Grace Alone getting revenge on him and Steven. The Doctor tried to contain the Vardan woman, but she escaped, only to be foiled by Steven's granddaughter, Sida, using the copy of the Doctor. Steven then sent the Doctor back to his body on Earth in order for him to get back to the TARDIS, sending the copy along with the Doctor to improve his chances of surviving the trip. (AUDIO: The Locked Room)

Having found a second wind, the Doctor confronted the Cybermen when they intended to take humanity to Mondas to turn them into their kind, but his attempt at negotiation resulted in him and Polly being taken hostage aboard the Cyber-ship. Held prisoner, the Doctor comforted Polly while Ben helped delay the Cyberman until Mondas was destroyed by overloading on Earth's energies. While emerging from his sleep, the Doctor overheard Ben claim that it was "all over now," and became weary. (TV: The Tenth Planet) Having started his first regeneration, (TV: Twice Upon a Time) the Doctor left without Ben or Polly, defiantly claiming that things were "far from being all over". (TV: The Tenth Planet)

Walking in the snow, the Doctor caught a fading image of his late companion Oliver Harper, (AUDIO: The First Wave) as he insisted to himself that he would not change and that the entire idea was "ridiculous." He was soon called out by a kneeling figure, who claimed to be "the Doctor". (TV: The Doctor Falls) However, the Doctor, believing the TARDIS before him to be his own, instead thought that the man was another Time Lord come to reclaim it, only for time to freeze around them, and a World War I Captain to appear. Taking the Captain into the TARDIS to protect him from his pursuers, the Doctor saw that it was from his future and convinced of the Twelfth Doctor's identity, shortly before the TARDIS was pulled into a hovering spaceship. Sent out as a distraction, the Doctor was addressed as "the Doctor of War" by a glass avatar of the Testimony, who offered to trade the Captain for the Twelfth Doctor's deceased companion, Bill Potts. Now joined by his future self, the Doctor examined the interior of the spaceship, and realised that the glass avatar was based off of a real person due to being too asymmetrical. Managing to escape as the Twelfth Doctor's TARDIS was taken by the Testimony, the two Doctors, the Captain and Bill retreated to the First Doctor's TARDIS, where the Twelfth Doctor decided to visit "an old friend" to figure out what the Testimony was.

Arriving at Villengard, the Captain was attacked by a familiar creature, and left inside the TARDIS with Bill as the two Doctors journeyed towards a tower, briefly stopping to discuss their shared refusal to regenerate. When the Twelfth Doctor entered the tower alone, the First Doctor examined the wreckage and found the remnants of Dalek shells as he was joined by Bill, who revealed herself to be a glass avatar. Despite the initial shock of there being "a spy in the camp", the First Doctor was told the true purpose of Testimony and its benevolent agenda, just as the Twelfth Doctor learned the same from the Dalek's Pathweb. When the Doctors agreed that the Captain had to die at his allotted point in time, the Twelfth Doctor requested, much to the First Doctor's surprise, that they take him back, which was allowed by the Testimony.

Returning the Captain to 1914, the Doctor expressed his regret that "the universe generally fail[ed] to be a Fairytale," and promised to "make it [his] business" to look in on the Captain's family, the Lethbridge-Stewarts, as a favour. Hidden by a perception filter, the two Doctors watched as the Captain, now with no memory of having ever met them, prepared to meet his fate. Suddenly, Christmas carolling started up on both sides of the battlefield, and the Twelfth Doctor explained that he had adjusted the time frame by a couple of hours so that when time resumed for the Captain and his opponent, it would be the beginning of the Christmas Armistice. As the Twelfth Doctor explained the Armistice to the First Doctor, the Captain called for aid for his wounded opponent and the First Doctor realised that his future self maneuverered events to save both men's lives, and that that was "what it [meant] to be a Doctor of War." After watching the Armistice for a few hours, the First Doctor admitted that he felt ready to regenerate, but questioned his future self on his decision, with the Twelfth Doctor only answering that the First Doctor would have to find out "the long way round" before the First Doctor departed to his TARDIS. (TV: Twice Upon a Time)

Death
Now inside the TARDIS and glowing with more regeneration energy, the Doctor managed to set the coordinates to return it to Antarctica in 1986. (TV: Twice Upon a Time) As the TARDIS' controls continued to operate on their own, he opened the doors for Ben and Polly before collapsing unconscious to the floor, having lost the energy needed to keep his old body going. Before the astonished eyes of his friends, the Doctor regenerated for the first time, transforming into a much younger man, (TV: The Tenth Planet) at the age of 450-years-old. (PROSE: Iceberg)

Post-mortem
While still adjusting to his new body after his first regeneration, the Second Doctor saw his first incarnation in his reflection. (TV: The Power of the Daleks)

When under attack by a space amoeba, the Fourth Doctor briefly turned back into his first incarnation. (COMIC: Timeslip)

In a dream, the Fourth Doctor encountered the First Doctor in a heavenly garden also occupied by his other previous incarnations, which made him aware that his own regeneration was on the horizon. (PROSE: Into the Silent Land)

When trapped in a dimensionally-unstable pocket universe controlled by Iam and, the Sixth Doctor's morphic print was destabilised, causing him to unwillingly regress back through his previous incarnations as his body sought a stable morphic print. He eventually "settled" into his first body, which remained stable long enough for him to return to the TARDIS and return to his current self. (PROSE: State of Change)

When the Timewyrm sent Ace into the Seventh Doctor's mind, she encountered the First Doctor as an elderly librarian. (PROSE: Timewyrm: Revelation)

When the Tenth Doctor was confronted by Es'Cartrss within the TARDIS' Matrix, he summoned the First 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 were created instead. This included the First Doctor. (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 First 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 First Doctor, appeared inside it to defend themselves as well. Standing with his latest incarnation, the First Doctor debunked auditor Sondrah's accusations of him being a pestilence on the Earth. 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 First Doctor walk past her when the Eleventh Doctor claimed that "everything around [her] was [him]". (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 incarnations, including the First 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 First Doctor, who appeared in the form of "a frail young boy." (AUDIO: The Lost Magic)

Undated adventures

 * The Doctor allowed Susan to borrow the TARDIS for a trip to Venus, but she instead landed on Skaro, where she had an encounter with the Daleks. (COMIC: The Message of Mystery)
 * The First Doctor spent "quite a lot of time" in the 1990s. His eighth incarnation would recall this period of his first life as "not a happy time." (PROSE: Interference: Shock Tactic)
 * Alongside the Master, the Doctor played a part in the Cloister Wars. (TV: The Magician's Apprentice)
 * On a Thursday in the summer of 1966, the First 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)
 * In 1630, (PROSE: Night of the Intelligence) while helping the monks at the Det-Sen Monastery fight off a bandit attack, the Doctor was entrusted with the monks' ghanta by the High Lama, Padmasambhava, but he left the monastery before the battle concluded. (TV: The Abominable Snowmen)

Alternate timelines
In an alternate timeline created by the Discordia, the Doctor had a passionate romantic relationship with River Song that began in his first incarnation, having married her by his fourth incarnation. The Doctor would have difficulty "smuggling" River into the Capitol through the Cloisters. (AUDIO: Someone I Once Knew)

In an alternate timeline created by the Black Guardian as revenge on the Doctor, the First Doctor never left Gallifrey, and eventually became Lord President. However, it also left Earth to be invaded by countless aliens, who were then at war over the planet. The Seventh Doctor, Benny, and Ace, with instructions from the White Guardian, were able to retrieve the Key to Time to set the timeline straight. (COMIC: Time & Time Again)

When the Valeyard used his control of the Dark Matrix to corrupt the Doctors, the First Doctor's corruption occurred when he murdered other Time Lords in order to leave Gallifrey. This timeline was later undone by the Seventh Doctor. (PROSE: Matrix)

In an alternate timeline where the Cybermen allied with Rassilon to take over history, (COMIC: Supremacy of the Cybermen) they attacked the First Doctor on the day that he was supposed to leave Earth with Susan, Ian, and Barbara. (COMIC: Prologue: the First Doctor)

When the TARDIS crashed on Tick-Tock World, the Doctor, along with Ian and Barbara, were devoured by the Xesto, creatures that consumed time and all possible futures. He then woke up in a dream-like dimension, encountering other alternative outcomes of how he could have been devoured. A woman helped him to make contact with Susan, as the state of "death" on the planet meant someone would be disposed outside time itself. As he was fading away, he realised the woman was an older version of his granddaughter, and he persuaded the younger Susan to touch her older self. Their violation of the Blinovitch Limitation Effect caused an explosion which allowed the older Susan to avert the original crash. (AUDIO: Tick-Tock World)

Personality
In his elderly years, the First Doctor was an unreadable, guarded figure who was, at first, slow to trust newcomers who learnt of him, but once his trust had been earned, he would show another side of himself as a staunch anti-authoritarian with a mischievous streak. (TV: An Unearthly Child) He was protective of the young women he took on as companions; they reminded him of his granddaughter, Susan. (TV: "Bell of Doom")

The Doctor held himself in high regard and was prone to criticise those whom he felt were naïve or primitive compared to his intellect. (TV: An Unearthly Child, The Reign of Terror) However, he possessed compassion, warmth, and wit that made up for his egocentric nature, serving to act as a mentor and guardian figure to his companions. Originally a very difficult and curmudgeonly person, (TV: An Unearthly Child, The Edge of Destruction) the First Doctor matured from an apparent selfishness and became more inviting. (TV: The Rescue, The Time Meddler, The Smugglers) His happier, kinder characteristics fostered when he began to acquire an entourage of companions to accompany him throughout the wonders of the fourth dimension and learned to be a caregiver with a sense of justice in a universe afflicted by evils. (COMIC: Hunters of the Burning Stone)

Upon leaving Gallifrey, the Doctor did not see "good" as "a practical survival strategy", as "it require[d] loyalty, self-sacrifice, [and] love". (TV: Twice Upon a Time) During his early travels, the Doctor was satisfied with merely observing the universe, due in part to having the non-interference policy ingrained into his psyche. As such, he was willing to allow civilisations to be destroyed without aiding them, until Susan convinced him to save Earth from the Cold, which gave him "a feeling of satisfaction". (PROSE: Time and Relative)

When the Doctor first met Ian and Barbara, he abducted them and set the TARDIS console to shock Ian into unconsciousness. He justified his actions by claiming he was keeping himself and Susan safe. He regarded humans as primitives, (TV: "An Unearthly Child") and contemplated killing the mortally wounded Za so that he would not slow him down. When Ian caught him apparently ready to bludgeon the man with a rock, the Doctor explained he merely wanted Za to draw him a map, (TV: "The Forest of Fear") but this was, in fact, a lie to cover up his murder attempt. (PROSE: The Eight Doctors) When first visiting Skaro, the Doctor was willing to risk everyone's safety so he could satisfy his own curiosity, resulting in them nearly dying from radiation poisoning in the prison cells of the Dalek city. (TV: The Daleks) He also threatened to throw Ian and Barbara into space after accusing them of sabotage. When proven wrong, the Doctor humbly apologised. (TV: "The Brink of Disaster") He later planned to leave Susan, Ian and Barbara in Salem Village while he took the TARDIS into the Time Vortex to repair it, but was talked out of it in favour of staying in the village a few days to repair the ship. (PROSE: The Witch Hunters)

Despite this, even during his dark beginning, the Doctor showed signs of a kinder persona, being quick to bargain with the Tribe of Gum for Ian's safety. (TV: "The Cave of Skulls") He also offered to help build a ship for the Daleks to leave Skaro in return for Susan's safety and took it upon himself to ensure the Thals were not threatened with extinction. (TV: "The Rescue") The Twelfth Doctor later opined that his experience on Skaro shaped his identity for the better. (TV: Into the Dalek)

As the Doctor travelled more, he began to thaw and help people, albeit reluctantly at times, such as on Marinus, where he only agreed to help Arbitan restore the Conscience of Marinus after he was blackmailed, (TV: The Keys of Marinus) and more willingly on other occasions, such as when he landed during the 22nd century Dalek invasion. (TV: The Dalek Invasion of Earth) Later, the Doctor was quick to help the Rills in their fight against the Drahvins on a doomed planet, noting that bias based on appearance was unwelcome, (TV: Galaxy 4) negotiated the release of from the Daleks, despite peace not being brokered between the two, (TV: The Daleks' Master Plan) and, upon witnessing the persecution of the "savages", was quick to ally himself with them against the Elders, defying their suggestions that progress was based on exploitation, branding it as "protracted murder". (TV: The Savages) However, when the Doctor heard his twelfth incarnation declare the Earth to be protected, he failed to realise that his future self was referring to himself, due to being in the "early days". (TV: Twice Upon a Time)

Though he told Braxiatel that it was pointless to do a good deed for someone else, as the gesture often went unappreciated and only brought trouble, (PROSE: The Empire of Glass) the Doctor believed that "it [was] far better to let the guilty go unpunished than to make the innocent suffer". (PROSE: The Witch Hunters)

While he claimed to "never touch" alcohol, and would decline it when offered, (TV: The Gunfighters, The Smugglers) the Doctor enjoyed wine. (PROSE: The Empire of Glass)

The Doctor believed that there was a reason for everything in the universe, (TV: The Chase) having left Gallifrey to find what "[kept] the balance between good and evil in [the] appalling universe", and why "good prevail[ed]" despite not being "a practical survival strategy" in the face of "evil". (TV: Twice Upon a Time) He once questioned if saving an entire planet of people was more important than saving an individual life. (PROSE: Venusian Lullaby)

The Doctor came to the defence of established history when Barbara attempted to alter the nature of the Aztec civilisation, claiming that not a single line in history could be altered. (TV: The Aztecs) Nevertheless, he gave first aid to the injured de Tornebu, justified stealing clothes based on the fact they were already stolen, and finding his shoplifting of the clothes humorous, and tried to convince King Richard to carry out his peace plan. (TV: The Crusade) However, when he first challenged, the Doctor quickly labelled him a "time meddler" and quickly continued to uphold his belief that history could not be changed, (TV: "Checkmate") and again backed up his previous ideal that it was permissible to save people who were not directly contributing to historical events while in Paris during August 1572. (TV: The Massacre) However, after watching the Twelfth Doctor alter time slightly to save the lives of two men, the First Doctor took his future self's meddling to be a good indicator of the man he would eventually become. (TV: Twice Upon a Time)

The Doctor did not associate himself with a specific culture, claiming to be "a citizen of the universe, and a gentleman to boot". (TV: The Daleks' Master Plan) He described himself as having "the directional instinct of a homing pigeon", (TV: The Chase) and did not allow others to intimidate him. (TV: "The Unwilling Warriors", The War Machines)

The Doctor once claimed to Vicki that he was "a wanderer and a survivor" in "the fourth dimension of space and time", as well as "a refugee from an ancient civilisation, cut off from [his] own people by aeons of time and universes far beyond human understanding". (PROSE: The Empire of Glass)

Reflecting on his successors, the First Doctor labelled his third and second incarnations as "a dandy and a clown", and joked when meeting them for the first time to battle Omega that they had yet to do anything. However, he did get along with them to a point, though got noticeably frustrated when the Second Doctor was slow to catch on. (TV: The Three Doctors) He also got on well with his fifth incarnation, admitting he did "quite well" after the Game of Rassilon and was reassured that his future was in "safe hands". (TV: The Five Doctors)

The First Doctor was confused by the mannerisms of his twelfth incarnation, such as his use of the sonic sunglasses, (TV: Twice Upon a Time) and admitted at first that he did not like him, leading to him making comments that he knew would wind him up, (PROSE: Twice Upon a Time) but eventually confided in him his fears of regenerating, and came to respect him after seeing him save two men from death. (TV: Twice Upon a Time)

Several of his future incarnations had a noticeably profound respect for the first incarnation, so much so that they dared not question his judgement, or argue in his presence. (TV: The Three Doctors, The Five Doctors) The Eleventh Doctor was an exception to this, looking upon his original incarnation with shame, branding him a "selfish idiot" and a coward, (COMIC: Hunters of the Burning Stone) with the Twelfth Doctor recognising that his past incarnations would let the First Doctor get away with whatever he wanted, but stated that he would not do the same. (PROSE: Twice Upon a Time)

The Eighth Doctor remembered the First Doctor as a "fierce old man". (PROSE: The Eight Doctors) The Twelfth Doctor considered his first incarnation to have been "eccentric, a bit mad, [and] rude to people," (TV: Hell Bent) and was rather shocked at some of his mannerisms, particularly his lack of political correctness (TV: Twice Upon a Time) that was deliberately exaggerated by the First Doctor to make his future incarnation feel uncomfortable due to his initial dislike of him. (PROSE: Twice Upon a Time)

The First Doctor's strongest relationship was with his granddaughter, Susan Foreman. He was always looking out for Susan, even lecturing her many times and telling her off. (TV: An Unearthly Child, The Sensorites) His last act of paternity towards Susan was to leave her in the 22nd century with David Campbell, a freedom fighter she had fallen in love with, to start her own life. (TV: The Dalek Invasion of Earth) His grandfatherly ways were then passed over to Vicki Pallister, (TV: The Chase) and Polly Wright. (TV: The Tenth Planet)

While Susan once described her grandfather as being a "great man", the Doctor considered himself to be very dangerous when roused. (AUDIO: Domain of the Voord, The Doctor's Tale) Geoffrey Chaucer, meanwhile, described the Doctor as being "a man of rare wit and temper, a philosopher." (AUDIO: The Doctor's Tale) Ian Chesterton once described the First Doctor as being "basically good, but bad-tempered, [and] mischievous" and also voiced that he "sometimes [didn't] trust him". (PROSE: Venusian Lullaby)

When recalling her encounter with the First Doctor to, Ace described him as "sweet". (PROSE: No Future) When the Eighth Doctor had a tarot card reading, the First Doctor was identified as "the Hierophant". (PROSE: The City of the Dead)

After his struggle with the Celestial Toymaker, the Doctor felt increasingly unwell and speculated that his first regeneration was nearing, and hoped that his successor would be a better man than he was. However, he was fearful of the regeneration, knowing that it would change him beyond recognition. (PROSE: The Man in the Velvet Mask) Though he continued to be afraid of the change, (PROSE: Ten Little Aliens) the Doctor put on a brave face to comfort Polly Wright while dying as a prisoner of the Cybermen. After Ben rescued them, the Doctor made his way back to the TARDIS, (TV: The Tenth Planet) and became determined to fight the regenerative process, branding "the whole thing" as "ridiculous". (TV: The Doctor Falls) His fear of regenerating grew during an encounter with his twelfth incarnation, where he learned he would become known as "the Doctor of War" to the Testimony, and saw recordings of the conflicts his future selves had participated in. However, after witnessing the Twelfth Doctor alter time to spare two lives on a battlefield, the First Doctor understood what he would truly become, and decided to return to the South Pole to regenerate, (TV: Twice Upon a Time) using the last of his strength to unlock the door for Ben and Polly. (TV: The Tenth Planet)

Habits and quirks
The First Doctor punctuated his speech with exasperated sighs, snorts, and the occasional mangled phrase or word. (TV: "The Survivors", "The Sea of Death", "Strangers in Space", "The Planet of Decision", "Trap of Steel", "Horse of Destruction", The Daleks' Master Plan) He also made a habit of repeatedly uttering "dear", (TV: "The Cave of Skulls", "Strangers in Space", The Space Museum) and "yes". (TV: "The Powerful Enemy")

The Doctor would utter, "Good gracious me", when he was surprised, (TV: "Strangers in Space", "The Powerful Enemy") and end his sentences with, "Hmmmm?". (TV: An Unearthly Child, The Reign of Terror, The Romans, The Chase, The Myth Makers, The Daleks' Master Plan, The Celestial Toymaker) When he wished to not engage someone in conversation, he would bluntly tell them to "go away". (TV: An Unearthly Child, The Aztecs)

He would address young women as "child", and younger men as "my boy", (TV: The Ark, The Tenth Planet) or in Ian Chesterton's case by his surname, although often the wrong surname. (TV: The Romans) When he saw someone killed, he would describe the killer as a "butcher", (TV: The Crusade) and he would often release a little chuckle when something made him laugh. (TV: An Unearthly Child, The Romans, The Time Meddler, The Celestial Toymaker)

When he disagreed with something, the Doctor would scorn and get angry – denying the facts his companions gave to him in these situations. (TV: The Edge of Destruction, The Chase, The Time Meddler) He was frequently sarcastic towards those around him, seemingly to elevate himself above lesser intellects. (TV: The Time Meddler) He would get particularly snappish with those who doubted the TARDIS could actually travel through space and time. (TV: "The Cave of Skulls", "The Watcher")

The Doctor tended to hold onto his lapels while speaking or thinking. (TV: The Edge of Destruction, The Sensorites, The Dalek Invasion of Earth, The Web Planet)

Whenever he coughed, he would waft his handkerchief around. (TV: An Unearthly Child) He also made a habit of biting down on his index finger when thinking. (TV: The Centre)

The Doctor often made speeches, (TV: "An Unearthly Child", "The Brink of Disaster", "Flashpoint", "The Traitors", "Bell of Doom") and had a knack for metaphors (TV: "The Cave of Skulls") and proverbs. (TV: "The Rescue", "The Brink of Disaster", The Keys of Marinus, "Strangers in Space", "Prisoners of Conciergerie", "The Dimensions of Time")

As he was on the run from the Time Lords, (AUDIO: The Five Companions) the Doctor never stated the nature of his own origins, other than to hint that Susan and himself were exiled from another place and time, (TV: "An Unearthly Child") and to state that he and originated on the same world. (TV: "Checkmate")

The Doctor was very particular about how others addressed him; he refused to answer to the name "Dr. Foreman", (TV: "The Cave of Skulls") disliked being referred to as "Doc", (TV: The Time Meddler, The Five Doctors) and also didn't like being called "Pops". (TV: The Tenth Planet)

Skills
The First Doctor was more of an intellectual incarnation, and would mostly leave the fighting to others, due to his older and frail appearance. (PROSE: The Eleventh Tiger) He was certainly a thinker when it came to defeating his enemies; strategising the best way of defeating or tricking them. (TV: "The Firemaker") Because of this, the Elders recognised him as a man of infinite wisdom, (TV: The Savages) with the Doctor believing that knowledge was the only way to defeat the "evil creatures" of the universe. (PROSE: Salvation) His broad range of knowledge also allowed him to make various complex calculations from memory. (PROSE: City at World's End)

Whilst normally peaceful, the Doctor would, when pressed, resort to hand-to-hand combat with an effectiveness which belied his age, (TV: "All Roads Lead to Rome", "The Lion", The Chase, The Daleks' Master Plan; PROSE: A Big Hand for the Doctor) usually relying on his intelligence to outwit his opponents and to find simple ways to deflect attacks. (PROSE: The Eleventh Tiger) At other times, however, the Doctor revealed age-related vulnerabilities, such as the rheumatism he suffered from, that flared up if he was exposed to cold, (TV: "The Final Phase") and Ian noted that the Doctor's moments of physical activity often left him more fatigued and weary than he normally was after the effort was over. (PROSE: The Eleventh Tiger) He had been trained to be a ninja while on Quinnis. (PROSE: The Devil Goblins from Neptune)

Having been taught by the Master, (PROSE: The Dark Path) the Doctor could perform hypnosis with his signet ring, utilising it to break Dodo Chaplet's mind control by the artificial intelligence WOTAN, causing her to sleep for two days and forget her ordeal. (TV: The War Machines)

Though he required spectacles for reading, the Doctor's eyesight was better than a human's. (PROSE: The Plotters)

The Doctor could drive a car, (PROSE: The Time Travellers) and ride a horse, though he found it uncomfortable to do so. (PROSE: Bunker Soldiers)

While the Doctor had virtually no control over his TARDIS, (TV: An Unearthly Child) due in part to piloting it by himself without the needed amount of pilots, (TV: Journey's End) he was able to pilot the TARDIS to Venus circa three billion years BC, explaining that, as it was close to the origin of the Universe, plotting coordinates was more stable, though the process was still difficult, causing the TARDIS to shake badly during the journey. (PROSE: Venusian Lullaby) After a period of time where Rassilon allowed him complete control over his TARDIS, (PROSE: The Witch Hunters) the Doctor had gained enough experience to return the TARDIS to 1986 Antarctica from 1914 Ypres. (TV: Twice Upon a Time)

The Doctor once claimed to be able to speak all the Chinese dialects. (PROSE: The Eleventh Tiger)

The Doctor was a skilled gambler, being able to win half of Asia in a game with Kublai Khan. (TV: "Assassin at Peking") Another ability of his was the ability to sense an alien presence, getting goose bumps upon seeing the Post Office Tower and claiming that there was "something alien" about it. (TV: The War Machines)

He was also quick to learn new skills when required; when trapped on the planet Avalon, the Doctor spent a few days being coached in the planet's "magic" by Kilvenny Odoyle, and was then able to hold his own against the powerful magician, Gramling, in a magical duel, at one point engaging Gramling on his own after his enemy had been weakened by Odoyle and Anni Glassfeather. (PROSE: The Sorcerer's Apprentice)

Appearance
In his youth, the Doctor had short, light brown hair, (COMIC: Vortex Butterflies) and claimed that he was considered "quite a looker". (PROSE: The Plotters) Though other accounts disagreed with her statement, (COMIC: Time & Time Again; TV: The Name of the Doctor) Iris Wildthyme claimed that, when the Doctor first fled Gallifrey, he looked younger than the Eighth Doctor, with his hair not yet greyed. (PROSE: The Scarlet Empress)

By the time he met Ian Chesterton and Barbara Wright, the Doctor appeared to be a man in his early sixties, (PROSE: Who Killed Kennedy) who had shoulder length, greyish-white hair that grew around the back of his head, and piercing blue eyes that rested under expressive eyebrows. (TV: An Unearthly Child) A part of the Doctor disliked being "trapped in an old, decrepit body". (PROSE: Ten Little Aliens)

Martin had been told by the head undertaker that the Doctor was "an old geezer with white hair." (TV: Remembrance of the Daleks) When Ace encountered the First Doctor in the Seventh Doctor's mind, she noticed that he kept his "silver hair swept back" and had a "long, hawklike nose". (PROSE: Timewyrm: Revelation) When Legion took on the appearance of the First Doctor, William Blake saw him as "an old man with neck length grey hair". (PROSE: The Pit) When she found his wanted poster, Bernice Summerfield described the First Doctor as "a dignified-looking white-haired man in an Edwardian frock coat". (PROSE: Sanctuary)

Sir Charles Summer described the Doctor as "an English gentleman in his early sixties, with imperious white hair swept back from his face and reaching almost to collar length, with haughty features and piercing eyes that burned with intelligence and wit." (PROSE: Who Killed Kennedy)

The Fifth Doctor described his first incarnation as an "old man", (PROSE: Five Card Draw) with the Eighth Doctor calling him a "white-haired old man with a fierce beak of a nose", (PROSE: The Eight Doctors) a "arthritic old buzzard" (PROSE: The Taint) and a "crotchety old man". (PROSE: Escape Velocity)

When Affinity took on the First Doctor's appearance, the Twelfth Doctor noted that his first incarnation was "an elderly gentleman," with his "white hair receded from a high forehead and spilled over the collar at the back of his neck." The manifestation was dressed "in a [typically Victorian] dark jacket and checked trousers with a thin black cravat." (PROSE: Silhouette)

Main attires
The Doctor affected a slightly eccentric Edwardian dress sense, wearing a black shawl collar double breasted Town Coat, a yellow tweed waistcoat over a white shirt with a black ribbon tie, grey tartan trousers, and shiny elasticated boots when he left Earth with Susan, Ian and Barbara. (TV: "An Unearthly Child") When brought to Vortis from Rome, the Doctor changed out of his Roman garb into a mustardy brown waistcoat and a cream ivory-coloured striped ascot to accompany his usual gear. (TV: "The Web Planet")

He wore a blue signet ring on the middle finger of his right hand, (TV: "An Unearthly Child", Twice Upon a Time) which had special powers, such as to unlock the door of the TARDIS. (TV: The Daleks' Master Plan) On one occasion, the ring appeared to both facilitate hypnotism and protect the Doctor from electrical shock. (TV: The War Machines) On occasions, he did not wear his ring and wore fingerless gloves instead. (TV: The Tenth Planet, The Five Doctors) He also often wore a small silver ring on the little finger of his left hand. (TV: The Dalek Invasion of Earth, The Time Meddler, The War Machines)

Occasionally he would wear a cape, (TV: Planet of Giants, The War Machines) or sport half-moon reading glasses. (TV: The Time Meddler, The Daleks' Master Plan, The War Machines) He also carried a monocle on a necklace. (TV: The Sensorites, The Web Planet, Twice Upon a Time; PROSE: The Sons of the Crab, Peril in Mechanistria, The Fishmen of Kandalinga)

For headgear, he would wear an Astrakhan, (TV: "An Unearthly Child", The Tenth Planet) or a white Panama hat. (TV: The Chase, The Daleks' Master Plan) He also used a smoking pipe on at least one occasion, (TV: "The Cave of Skulls") and also employed a walking stick given to him by Kublai Khan. (TV: Marco Polo)

Other costumes
When adventuring into Earth's past, the First Doctor would make changes to his wardrobe so as to blend in with the local population, (TV: The Reign of Terror, The Romans, The Crusade, The Gunfighters) and would gladly accept the vestments of extraterrestrial societies, as when he proudly wore the ceremonial garb of the Elders. (TV: The Savages)

Other matters
The First Doctor was one of only two incarnations ever known to smoke, (TV: "The Cave of Skulls") the other being the Eighth Doctor, although this only took place when the Doctor's mind and personality were briefly 'mixed up' with traits from his companion Fitz Kreiner. (PROSE: Halflife)

When the Doctor, Vicki Pallister, Barbara Wright and Ian Chesterton were being chased by the Daleks through time, he claimed to have built the TARDIS. (TV: The Chase) On the face of it, this statement appears to be in contrast with later incarnations and Time Lord authorities who claimed that the TARDIS was "borrowed"/"stolen", (PROSE: The Gallifrey Chronicles, TV: Planet of the Dead, The Big Bang) an account the TARDIS itself agreed with. (TV: The Doctor's Wife) It has also been suggested that the TARDIS was better described as having been "grown", rather than "built". (TV: The Impossible Planet) Though, the Doctor added various components to the TARDIS console to prevent himself forming a complete mental link to the ship that would have made it easier for the Time Lords to find him. (PROSE: The Taking of Planet 5)

Although the Doctor once claimed that he never touched alcohol and preferred milk, (TV: The Gunfighters) he accepted an offer of mead in 1066, saying that it was "delightful", (TV: The Time Meddler) drank Madeira with Samuel Pike (TV: The Smugglers) and shared a few glasses of Médoc with John Lucarotti. (PROSE: The Meeting)

The First Doctor always wanted to visit Traken. (AUDIO: The Toy) He would later do so during his second, (PROSE: The Astronomer's Apprentice) fourth (TV: The Keeper of Traken) and fifth incarnations. (AUDIO: Primeval)

The matter of this incarnation's age and how long this incarnation lived was unclear, although Susan once called him an adolescent by Time Lord standards; (AUDIO: Here There Be Monsters) shortly after his regeneration, his next incarnation stated that he was around 450 years old. (TV: The Tomb of the Cybermen)

Behind the scenes

 * When introduced in the script for An Unearthly Child, the First Doctor was physically described with the statement, "His clothes are bizarre."

Casting
Actors considered for the role of "Doctor Who", as he was then known, included Geoffrey Bayldon , Cyril Cusack, Hugh David and Leslie French. (Bayldon would later play an alternate version of the First Doctor in two Unbound adventures for Big Finish Productions: NOTVALID: Auld Mortality and NOTVALID: A Storm of Angels.) William Hartnell had, up until that point, mainly played small-time thugs and other unsympathetic parts in crime films and humourless military men in comedies. Producer Verity Lambert was inspired to ask him to accept the role after seeing him in his well-known role in, which convinced her that he could play a tough, yet shaded and sympathetic character.

During the First Doctor's tenure, other actors occasionally stood in for Hartnell, either for demanding scenes or due to Hartnell being ill or otherwise unavailable. Edmund Warwick stood in for Hartnell in one episode of The Dalek Invasion of Earth, and played the real Doctor in some scenes of The Chase when Hartnell was playing the Robot Doctor. In The Tenth Planet, Gordon Craig acted as a body double for Hartnell during the snowstorm scenes in the first episode, and then all of the third episode, after Hartnell was taken ill.

When the time came for the First Doctor to appear in the 1983 Children in Need anniversary special TV: The Five Doctors, actor Richard Hurndall was hired to play the role, standing in for William Hartnell, who had died in the mid-1970s. A clip of Hartnell as the Doctor from The Dalek Invasion of Earth preceded the opening titles, and Hartnell's name appeared amongst those of his fellow Doctors in the end credits.

During the 50th anniversary year, in 2013, Hartnell appeared in TV: The Name of the Doctor by way of manipulated stock footage and audio, allowing the actor to posthumously share dialogue with Jenna-Louise Coleman playing a "splinter" of Clara Oswald. Later in 2013, Hartnell was again represented via stock footage in TV: The Day of the Doctor, but with John Guilor providing newly recorded dialogue.

David Bradley played Hartnell himself, playing the First Doctor, in the 2013 docu-drama An Adventure in Space and Time. In 2017, Bradley was brought to the show proper, to play the First Doctor himself; the Doctor as played by David Bradley appeared at the end of TV: The Doctor Falls and in the entirety of the 2017 Christmas special TV: Twice Upon a Time. Bradley also voiced the First Doctor in Big Finish's audio series The First Doctor Adventures.

In audio, William Russell officially voiced the First Doctor for Big Finish's The Light at the End, having previously voiced him in narration form during all the Companion Chronicles audios that featured his own character Ian. Russell would then reprise the role when required in Early Adventures, while Peter Purves portrays him in the audios that feature Steven. After his casting, Elliot Chapman also began playing the Doctor in narration form in audios that feature Ben.

whoisdoctorwho.co.uk
The website whoisdoctorwho.co.uk had a list of sightings of the Doctor from which people had ostensibly been submitting to Clive Finch, a conspiracy theorist character from TV: Rose.

A submission from an 81-year-old Mrs. Smith mentions her working as an usherette at the Ritz Cinema in Totter's Lane, which was later demolished and turned into flats. In 1963, she encountered a version of the Doctor with white hair, and a younger girl Mrs. Smith presumed was his granddaughter. While watching a film on the fall of Rome at the cinema, she recalled the Doctor continuously tutting and muttering that it wasn't historically accurate. She "gave him a piece of [her] mind and sent him packing". He stormed towards the old junkyard and she never saw from him again. She presumed Clive's Doctor posted on the website, the Ninth Doctor, was some sort of relation, rather than another incarnation like the first.
