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. 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, learning to be a caregiver and mentor with compassion, warmth and wit that made up for his egocentric nature, as well 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 David Campbell, 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 Pallister. 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, Troilus, whom 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.

At some point, the First Doctor, going by the name Dr. Who, also travelled with John and Gillian, his other grandchildren.

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 their timeline while travelling through time, what really transpired to the Doctor during his time on Gallifrey was hard to decipher.

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
For many pressing reasons, (TV: Twice Upon a Time) the Doctor stole a TARDIS (TV: The War Games) and fled his home planet with his granddaughter, Susan Foreman. Though he intended for he and Susan to someday return, (TV: An Unearthly Child) the Doctor knew that they could not. (TV: The Massacre) Immediately after their escape from Gallifrey, the Doctor and Susan encountered Humans for the first time, on either Iwa (PROSE: Frayed) or the Earth's Moon. (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. 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)

One night, the Doctor told Susan a bedtime story about them meeting the Five O'Clock Shadow. (PROSE: The Five O'Clock Shadow)

When visiting a planet with two suns, the Doctor cut himself with a strange plant and fell ill as a result of the infection that followed. Susan had to venture outside, in an abandoned research centre on Rua to find some cure; she managed to do so and was able to cure the Doctor. When he recovered, he noticed Susan crying over a video, and asked her what had happened; she then told him about her encounter with the terrorist known as the Butcher and the security team sent to deal with him, about the part she played in his demise and how she then found out what his real motives were. The Doctor comforted her by saying she did her best by saving his life, and nothing else mattered, even more so because they must not interfere in other people's business. When Susan pointed out he didn't used to think this way, the Doctor replied that now they were travelling, and couldn't use their abilities to manipulate others, especially as this could not end up in a good way. Susan, however, could see he wasn't really sure on the matter (AUDIO: The Sleeping Blood)

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

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 Finch, a salvage operative waiting for her partner Tino Driscoll. 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 quickly made their departure after saying goodbye. (PROSE: The Arboreals)

The Doctor was forced to land the TARDIS on Earth in the 1960s to make some repairs. After fixing the TARDIS, he went to look for Susan, who had gone exploring, and encountered the Cybermen. After finding Susan, the Doctor defeated the Cybermen by blasting them with sound waves of music. (PROSE: Dr. First)

The Doctor and Susan visited a restaurant owned by a man named Rowson, (PROSE: Indian Summer) fought "homicidal earthworms" that excreted laughing gas with Aldridge, (PROSE: A Big Hand for the Doctor) and visited Jabalhabad, India, in 1843, whilst they were touring India by elephant.

Aided by his other incarnations and their companions, the First Doctor and Susan helped Dan Dare to fight off the Mekon and his army of Treens, Daleks, Ice Warriors, Cybermen, Sontarans and Draconians in 1991. After the Mekon was subdued by a barrage of Red Noses, the First Doctor helped collect donations from the defeated army. (COMIC: Comic Relief Comic)

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 the queue to see the baby at their christening, he accidentally dropped the silver knife he planned to use to kill them. 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 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, she and the Doctor 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 16th 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 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 afterwards, 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 recruited into the French resistance in World War II known as the Shakers, 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)

The Doctor and Susan were present in London during the coronation of Elizabeth II on 2 June 1953, where they were pursued by a creature with lasers spewing out of its one eye. They were saved when the creature was subdued by Eva De Ville. (COMIC: Where's the Doctor?)

Searching for a new home
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) Around this time, 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)

When the TARDIS landed in Berlin in November 1932, the Doctor decided to go and visit a convention of scientists at the Kaiser Wilhelm Institute, wanting especially to meet the director of the Institute, Fritz Haber. However, he made the mistake of exchanging Ancient Roman gold coins for banknotes at a local jewellery shop. This brought suspicions on him and Susan because Haber was believed to be studying a way to extract gold from seawater. As a consequence, he was apprehended for interrogation by German secret service, together with Haber, and kept in an unused lab in the Institute. He was eventually freed when Susan tricked Pollitt, a British agent, into showing him the secret of their gold. (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)

Settling in Totter's Lane
According to one account, while the TARDIS was in flight in deep space during 1963, the Father of Time materialised inside the TARDIS control room, having resolved to test the Doctor. He forced the TARDIS to land on a radioactive planet that had begun to be torn apart from the inside, with the "Test of Time" being to escape from the apocalypse. The Doctor and Susan took refuge down a mineshaft, and "rode out the storm" safe at the very heart of the planet. Satisfied with their quick thinking, the Father of Time transported them back into the TARDIS, which he deposited at 76 Totter's Lane, London in the 1960s, foretelling that they would find "a new life" there. (COMIC: The Test of Time)

According to another account, while 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, though 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)

According to yet another account, the TARDIS landed on Barnes Common. (PROSE: Doctor Who in an Exciting Adventure with the Daleks)

Hiding on Earth
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 affect 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, even though he had access to the appropriate currency, (AUDIO: Hunters of Earth) and sold a few "harmless" alien artefacts to Fyodor, a frightening alien disguised as an old man, in order to pay for Susan's school lunches. (AUDIO: The Shoreditch Intervention)

According to another account, Susan took on the surname "English" and the Doctor had Barbara Wright tutor her in history at twenty pounds a week while he busied himself with research. (PROSE: Doctor Who in an Exciting Adventure with the Daleks)

Although the Doctor did not venture out very often, (TV: An Unearthly Child) he had 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 for the Doctor. (GAME: The Eternity Clock)

According to one account, the Doctor did not have the Hand of Omega when he left Gallifrey. While walking one evening to pick up Susan from school, he encountered his seventh incarnation lurking in a dark street. The Seventh Doctor revealed that he had brought the Hand of Omega, and, claiming that the Hand knew what to do, left without revealing any details of his life to his bewildered younger self. (PROSE: Echoes of Future Past)

On one cold evening, the Doctor and Susan watched a film at a theatre in Shoreditch. Afterwards, the Doctor and Susan got lost in the dense fog, eventually meeting 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 levelled during the London Blitz two decades earlier. The Doctor postulated that Susan's action likely freed Joan and her mother from their "nightmarish existence", but he wasn't sure. (PROSE: Ash)

On 1 and 2 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, taking five trips to get there. He then embarked on his journey back to Susan in 1963. (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)

The Doctor landed in London during the Great Fire of 1666, where he reluctantly rescued the Mortimer family: farmer George, his wife Helen and their children, Ida and Alan. Much to his annoyance, they believed he was a warlock and the TARDIS was powered by magic. The TARDIS 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)

The Doctor eventually arrived back in 1963 at the exact instant he had departed. He claimed to have had an eventful trip, but upon inspecting the TARDIS logs, Susan noted that he'd taken five trips to reach Pluto, and more than a dozen to get back to Foreman's Yard. On his return, the Doctor told Susan that the TARDIS had been damaged taking the Cold to Pluto, but he insisted that he'd "have it fixed in no time". (PROSE: Time and Relative)

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) On 7 August 1963, (AUDIO: The Shoreditch Intervention) the Doctor hid the Hand of Omega at an undertaker's. (TV: Remembrance of the Daleks)

The Doctor was placed on trial for murder after he killed the werewolf Roberta Sampson with a silver bullet in self-defence, but was acquitted by the jury, which was made up partly of his second, third, fifth and eighth incarnations. (PROSE: The Juror's Story)

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 1963, after legally purchasing parts to repair the TARDIS from Magpie Electricals, the Doctor was threatened by a group of teenagers, before they stopped and apologised. When the Doctor arrived at a warehouse to collect the parts, Colonel Rook revealed that he had tricked the Doctor into meeting him, as Rook wanted the Doctor to fight in a war and Susan to help in Britain's ESP experiments. When Susan and Cedric Chivers 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. (AUDIO: Hunters of Earth)

When Susan was accompanied back to the 76 Totter's Lane by her new history teacher, Dr. River Song, the Doctor dismissed her quite brusquely, inviting her to "mind [her] own business". (AUDIO: An Unearthly Woman)

When a thick fog engulfed Shoreditch, the Doctor decided to pick Susan up from Coal Hill personally, but, when he arrived, the school came under attack from humanoid figures with blood covered faces. With the aid of Shivani Bajwa, the Doctor was able to figure out that the wolf-like figures were aliens and that the fog was turning humans into Space wolves. After Shivani was transformed into a wolf, the Doctor restored her and, using his signet ring, he transmitted a message through the fog to get the wolves to retreat. However, his manipulations to the fog caused Shivani's flower garden to die out, so he promised to deliver roses to help the garden regrow. (PROSE: Doctor Who and the Horror of Coal Hill)

Meeting Ian and Barbara
After investigating an alien insect that he planned to return home, (PROSE: Those Left Behind) the Doctor returned 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. (TV: An Unearthly Child) According another account, the Doctor first met them when they were involved with a car crash on Barnes Common in which Susan was injured. He took Susan back to the TARDIS, but had to return to the crash site to retrieve her TARDIS key. When they followed him to the TARDIS and forced themselves in, the Doctor launched the TARDIS, kidnapping them so they couldn't tell anyone about him. (PROSE: Doctor Who in an Exciting Adventure with the Daleks)

They travelled to prehistoric times, (TV: An Unearthly Child, AUDIO: To the Death) though another account states that they went straight to Skaro. (PROSE: Doctor Who in an Exciting Adventure with the Daleks) 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. (TV: An Unearthly Child) While imprisoned, Barbara told the Doctor the story of Godfather Death by the Brothers Grimm, a story that would stick with him for many incarnations. (PROSE: The Knight, The Fool and The Dead)

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 continue his murderous plan. (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.

When the TARDIS landed on Skaro (TV: An Unearthly Child) in early 2064, (PROSE: Peaceful Thals Ambushed!) 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. In the city, the Doctor and his friends were captured by the Daleks. Having escaped, they assisted the Dalek's enemy, the Thals, in an attack on the Daleks city. 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)

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, ending the fault, and apologised to his companions. (TV: The Edge of Destruction) After this incident, the Doctor's relationship with Ian and Barbara 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 1963. 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)

Finding themselves in what appeared to be an English forest, the TARDIS crew 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. 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?)

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 travellers. However, the Doctor inadvertently foiled the attempt with his walking stick and, when a more open attack began, the TARDIS crew fled back to the TARDIS. (COMIC: The Forgotten)

When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the First Doctor received the call from his TARDIS food machine. However, he was unaware to what was happening, instead thinking that the food machine was broken. Before he could try to fix it, the Sixth Doctor arrived in his TARDIS and installed a button on the console to expel a pandimensional entity from the Fourth Doctor's TARDIS. (WC: Doctors Assemble!)

On a "night" in the TARDIS, the Doctor led his human friends on a tour of his ship before he went to bed. (COMIC: In-Between Times) Landing on an unnamed planet, the Doctor, Susan, Ian and Barbara found a path of skulls laid to honour the dead. (COMIC: The Path of Skulls)

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. (TV: The Keys of Marinus)

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. (TV: The Aztecs)

Arriving in Afghanistan in 1842 during the First Afghan War, the Doctor lost Ian when he was kidnapped by a brutal Gilzia chieftain called Gul Zaheer. Unable to track them down, the Doctor spent a month gathering Afghan allies to help him rescue Ian and another British prisoner, Symonds. But he was too late to stop Zaheer killing Symonds, so an enraged Ian killed Zaheer by throwing him into a pit. (PROSE: Mire and Clay)

During a visit to Chicago in 2006, the Doctor lost the TARDIS in a bet with a businessman named Buchanan, who intended to auction off the time machine. Hiring a 60s Oldsmobile 88, the Doctor and his friends travelled to Arizona, Texas, New Mexico, Oklahoma and Missouri, and the Doctor finally won the TARDIS back in Santa Monica. (PROSE: The Mother Road)

The Doctor next travelled to London during World War II and discovered the Bansharai, alien shapeshifters who survived on emotions, had been posing as dead people to make the wishes of their loved ones come true. (PROSE: Tell Me You Love Me)

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 regained their lock. (TV: The Sensorites)

Greatly agitated by Ian and Barbara's remarks on his piloting, the Doctor landed the TARDIS on board the Endeavour sailing ship in 1770. There, he and Ian met Captain James Cook, but, before Susan and Barbara could exit the ship, it was tossed overboard in a violent storm. Greatly saddened by the loss of the girls, the Doctor and Ian continued on the Endeavour's voyage for several months towards Australia observing the transit of Venus along the way. Their time on the Endeavour ended when they discovered Susan had managed to swim out and attach a line to the sailing ship from the TARDIS and so be pulled along behind it. The travellers' joy at being reunited was short lived when the Doctor became disgruntled again because the TARDIS floor was now covered in patches of water. (AUDIO: The Transit of Venus)

The TARDIS then landed in France in July 1794 in the middle of their revolution. They were immediately caught in the depth of the war, and Ian, Barbara and Susan were all sentenced to death. The Doctor helped find an English spy named James Stirling who could help them to escape. Escaping their jail cells, they made their way through the French and back to the TARDIS, where they made a narrow escape. (TV: The Reign of Terror)

After escaping from France, the Doctor wanted to relax, but found himself on a planet with a fast time rate, and discovered that the entire civilisation of the planet had been based around him, Ian, and the TARDIS. He and Ian then watched the rise and fall of the civilisation in a matter of minutes. (AUDIO: Rise and Fall)

After the TARDIS sustained some damage, the crew stayed on the planet Fragrance for a while, with the particular atmosphere of the planet caused them to create a strong friendship with a family of locals, to the degree that the Doctor gave the parents of the family, Iamb and Rhyme, a guided tour of the TARDIS when it was repaired. However, when Barbara refused to requite the love of their eldest son, Rhythm, and condemned him to death in doing so according to the usages of the planet, the Doctor sided with Ian and stopped Barbara from changing her mind. He then watched with the others as the young man went across the yellow arc of the planet, walking towards his fate. (AUDIO: The Fragile Yellow Arc of Fragrance)

After leaving Fragrance, the TARDIS landed in the Hanging Gardens of Babylon in 323 BC, where the crew were welcomed by Alexander the Great to his court. They watched as the closest friends of Alexander died as victims of a plot to eventually kill Alexander himself. In the end, when Alexander was poisoned and started to grow weak, the Doctor offered to keep him alive through a rudimentary artificial lung. However, Alexander refused and accepted his fate, but not before asking the Doctor what his legacy would be. The Doctor told him that, though his empire was not to survive without him, Alexander's fame would live forever. (AUDIO: Farewell, Great Macedon)

Shortly afterwards, the Doctor announced to Ian and Barbara that he had found a way to take them home. However, as he was about to do so, the TARDIS was drawn to a nearby dying planet, landing near a giant crystal pyramid. The crew were greeted by the robots living in the pyramid and brought to their leader, the Perfect One, a robot infused with an extraordinary similarity to human brain, to the point that he wished to actually become one. The Perfect One thought that the TARDIS crew belonged to the race of its creators, the Masters of Luxor, and required them to help him become human. When the Doctor claimed that that was impossible, the Perfect One decided to imprison them, but the Doctor and Ian managed to escape. In a nearby canyon under the ground, they found a crypt where Luxor, the creator of the robot, froze himself in a cybercoma. The Doctor and Ian woke him up and brought him back to the pyramid, with the intention of having him confront the Perfect One and prove to him he was just a machine. This resulted in the Perfect One losing control and destroying the pyramid and the other robots out of rage and despair. The TARDIS crew managed to escape in the mayhem. (AUDIO: The Masters of Luxor)

The Doctor stopped a suicidal crew leader, Provost Rowd, from wiping out the last remnants of the dying Metraxis, and he later assisted a new leader, Egrabil, to find a new home for the Metraxi. (AUDIO: A Star is Born)

Arriving in 20th century Russia in pursuit of an alien artefact, the TARDIS crew met Grigori Rasputin and learnt that the artefact had driven some hunters from a nearby village mad. As they progressed to the hut where the object was kept, the influence of the artefact affected both the Doctor, who grew weaker to the point of almost dying, and Susan, who seemingly was driven mad and fled into the forest. The Doctor got better when Rasputin grabbed the object and absorbed its knowledge of the future. With Ian's help, the Doctor was able to drain almost all knowledge out of Rasputin's mind, only leaving some traces of it. (AUDIO: The Wanderer)

The TARDIS crew decided to spend some time on holiday in 5th Century Alexandria around the time where the famous Library would be destroyed. The Doctor greatly enjoyed reading the books contained in the rich collection of the place, but was greatly displeased when Ian started forming a close relationship with the philosopher Hypatia, because he feared that would lead her to discover their secret. He then decided to depart, but stopped when Ian brought him a book, which the Doctor immediately recognised as belonging to the Mims and containing a detailed plan of invasion for Earth. He wanted to take it away, but Hypatia stopped him, moments before the Mims attack the Library to retrieve the book. In the following confrontation, the book was destroyed, and the Doctor, using a rudimentary megaphone, was able to talk to the Mims and persuade them they had nothing to fear anymore. The crew then departed, but not before the Doctor managed to sneak onboard some books he saved from the destruction of the Library. (AUDIO: The Library of Alexandria)

The TARDIS landed in Seville, where the Doctor asked Barbara to show him around, as she had once been there on holiday. He pretended to be a cardinal from Rome with Susan in order to try and release Ian from the Spanish Inquisition, but he was found out and sentenced to death before Susan and Barbara saved him. When he heard from Barbara that Ian went to Cadiz to help Esteban Aribi on his mission, the Doctor thought he was trying to change history, so attempted to stop him. But quickly found out that Ian was part of history and his intervention would not change anything. (AUDIO: The Flames of Cadiz)

The TARDIS landed on Destination, where the Doctor encountered for the first time since leaving Gallifrey. The Doctor was at first willing to sit and watch the city people and the Dalmari resolve their war before deciding that, as a member of the Master's race, it was his responsibility to do all he could. Spending two years ruling the planet, the Doctor brought peace to Destination before Ian and Barbara, having overpowered the Master, returned with the TARDIS whereupon the Doctor locked the Master away, saying that one day he might come back. (AUDIO: The Destination Wars)

The TARDIS then landed in New York City in the year 1888, shortly before the Great White Hurricane where they were caught in a gang scuffle. While Ian was injured and taken to hospital, Susan had been taken away by Patrick Ellis with the Doctor's outrage at the police over this resulting in him being arrested for a night. Befriending Patrick's brother, Daniel Ellis, the Doctor found himself caught in the gang war between the Alley Dogs and the Wild Boars as he tried to reunite with Susan, brokering a temporary peace between the gangs and the police to rescue her and Patrick from the ice. Upon returning to the TARDIS, the Doctor attempted to use a temporal slingshot to return Ian and Barbara to their time. (AUDIO: The Great White Hurricane)

The slingshot took them to the planet Ashtallah, home of the Ashtallans, an immortal race with prodigious healing abilities. After witnessing their cells quickly healing Barbara, the Doctor discussed many scientific concepts with Brenna before a mysterious plague began killing the aliens. After the Doctor had helped Brenna create a method via which the Ashtallans could reproduce, Susan found that Sharlan had been killing their people, via a sample of Barbara's blood. Once the spread had been halted, the group left the planet, pondering the impact they'd had on the Ashtallans. (AUDIO: The Invention of Death)

When the TARDIS landed in 19th century Japan before it was opened to Westerners, the Doctor and Barbara were taken prisoner at the orders of the daimyo Takagi Mamoru, while Ian and Susan managed to escape, as Mamoru suspected the two of being spies from England, sent to spy on his preparation for a revolt against the Emperor, who was about to open the country to strangers. The Doctor and Barbara tried to escape, but ended up being involved, together with Ian and Susan, in a battle between Mamoru's samurais and the Emperor's forces. As a defeated Mamoru sat in sadness, the Doctor comforted him, telling him that it would not be the end for Japan, and sharing in their common feeling of loneliness due to old age. The crew then departed after Susan retrieved the TARDIS from a nearby swap, where it had fallen into the water. (AUDIO: The Barbarians and the Samurai)

Soon afterwards, the TARDIS landed in Tyre, where they won the favour of Princess Elissa and the ire of King Pygmalion. The group attempted to flee on the king's prized ship but the Doctor failed to board in time. Left behind, the Doctor was imprisoned before he befriended Aiyaruc who freed him and brought him to the site of the future Carthage. Reunited with his friends, the Doctor helped defeat Pygmalion's invasion fleet, before using the TARDIS to paint him and his friends as emissaries of the gods, allowing them to go free. Shortly after take off however, the TARDIS wound up in a hostile region of space-time, crash landing on a temporally unstable planet. (AUDIO: The Phoenicians)

Thrown clear of the crash, the Doctor mourned for the loss of his ship, snapping at his companions, especially when Susan claimed that the planet was inhabited by Xesto. When the group had met Horl and Katta, the Doctor theorised about the planet's unusual properties before the group was taken to see Nocta, who'd survived so long by hiding in a Zero Cabinet. When exploring the ship that held the Cabinet however, the Doctor was devoured by a Xesto. The nature of death on this world left him trapped outside of time with alternate versions of himself and a mysterious woman. Though the woman showed him how to reach out to Susan, he quickly butted heads with her over his treatment of Susan before realising that she was a future version of his granddaughter. When both Susans met, the Doctor encouraged them to touch and exploit the Blinovitch Limitation Effect. Thrown back to the moment of the crash, the elder Susan encouraged the Doctor to listen to Susan's plan to redirect power from the TARDIS force field, allowing him to avert the crash. (AUDIO: Tick-Tock World)

A later attempt to use the fast return switch to get Ian and Barbara home, resulted in the group's return to Skaro, fifty cycles after their last visit. Brought to the Thal City, the Doctor was introduced to Tryana before the two, along with Ian, returned to the Dalek City to find the missing Susan and Jyden. Finding that power still thrummed in the city, the Doctor grew increasingly suspicious of Tryana before they reunited with the children and Tryana revealed herself to be in league with the Dalek Supreme who claimed to want peace. Remaining to validate this claim, the Doctor found a secret tunnel leading out of the City and was quickly taken prisoner as Ian escaped and Tryana was killed. Kept alive for the secret of the TARDIS, the Doctor was marched back to the Thal City where he was rescued. Free, the Doctor reprogrammed the ionising towers to attack the Daleks, after which Ian overloaded the power to the Dalek City, before the group left Skaro again. (AUDIO: Return to Skaro)

The TARDIS then landed in Ekaterinburg, shortly before the Russian Civil War, where Ian and the Doctor were quickly taken prisoner, befriending Makerenkov, a fellow prisoner. After the Doctor had confirmed the health of Nicholas II, Yakov Yurovsky took him to a forest where the Romanovs would be buried after their execution where the Doctor realised Makenrenkov to be part of the conspiracy. Racing back to the house, the Doctor gathered his companions only for Nicholas II to have already accepted death, urging the travellers to flee. Racing back to the TARDIS before they could be executed, the Doctor pondered the Laws of Time and whether or not he had a moral imperative to intervene, even with a fixed point in time. Before he could muse further, the TARDIS unexpectedly lost all power. (AUDIO: Last of the Romanovs)

Following the TARDIS suddenly losing power, Susan helped her grandfather force a system reboot that forced the ship to land in a sewer in the human settlement of Urth. Given the humans' xenophobia, the travellers were forced to submit to a genetic scan. Having only time to program one false reading into the machine, the Doctor insisted Susan go first, intending for Ian and Barbara to look after her, only for the genetic drift of humanity making Susan the only one of the four who actually read as human. Thrown into a cell, the Doctor befriended the gestalt being Brooskin whom he engaged in a medical and scientific discussion before Susan, in the good graces of Mummy Martial managed to free him and Brooskin. Freed, the Doctor liberated the settlement from Daddy Dominus before representatives from the larger group of human colonies arrived. Convinced that the problems would sort themselves, the Doctor led his companions back to the updated TARDIS and took off again, annoyed to find that his ship was still not working properly. (AUDIO: For the Glory of Urth)

When Susan pulled a Golithan Spiney Back Beetle out of the console, the Doctor was convinced that she'd reparied the TARDIS and made another attempt to return Ian and Barbara to their time only to wind up in 1601. When the four sought to see a play by William Shakespeare, they found the Globe Theatre shuttered and a volatile political climate. Rescued by Judith Shakespeare, the four were brought to Shakespeare's home. When Susan and Judith ran off, becoming involved in Lady Penelope Rich's plot to dethrone Elizabeth I, the Doctor confronted his granddaughter at the Globe but she refused to listen. After this had resulted in Shakespeare's arrest, Susan and the Doctor attempted to free him only for the Doctor to be arrested upon identifying himself. Speaking with Shakespeare again, the Doctor was soon freed by Queen Elizabeth, who had befriended Susan and brought a quick end to the conflict. When the time came to leave, Susan, Barbara and Ian expressed a desire to stay and see a play before an outside source activated the TARDIS and sent it flying away from England. (AUDIO: The Hollow Crown)

Soon after, the Doctor rescued Joseph Rennigan, the sole survivor of an American space mission that crashed on Mars, (PROSE: Rennigan's Record) and visited a dying world, where Barbara was infected by an alien parasite which distorted her memories. (PROSE: Nothing at the End of the Lane)

When the TARDIS was drawn out of the vortex by a mysterious noise, the Doctor, Susan, Ian and Barbara landed on EBV Nevermore. Here they encountered the ship's captain, Rostrum, who was a plant. The Doctor was appalled that Earth was making holes in the universe for navigational purposes but they ended up being navigational hazards. Susan told her grandfather about the First Mate and they both worked out that this was why Rostrum's leaves were dying as he was sabotaging the ship to save his universe. (AUDIO: Here There Be Monsters)

The Doctor, Susan, Ian and Barbara also visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963. (AUDIO: The Light at the End) Shortly after, the Doctor and Ian stopped a Blue plague in 2908 Prague. (PROSE: Room for Improvement)

When the TARDIS landed on Hydra, the crew became caught in the war between the refugees and the Voord, and the Doctor and Barbara first risked drowning and then were captured by the Voord. The Doctor healed himself thanks to a self-induced coma, but the Voord thought he was dead and disposed of him. The Doctor became the leader of Hydra resistance, and was eventually able to think of a plan to destroy the Voord's main central power station. The Voord leader, Nebrin, attempted to stop him by threatening Susan's life, but she was saved by another Voord, Tarlak, and the attack was eventally a success. Hydra was thus released, and the travellers could depart once again. (AUDIO: Domain of the Voord)

On the ship Endurance, the TARDIS crew were caught in the middle of a fight between the Last Borns, led by the scientist Myla, and their enemies, the Shifts, a lizard-like species also created by the scientist Myla. The Doctor and Ian were captured by the Shift's leader, Arran, and from him learned the whole story. Later, they were freed by the intervention of Myla and other soldiers and brought to the other ship of the Last Borns, the Resistance, but the Doctor was severely injured in the process and brought to the infirmary. As he laid there, the ship was attacked and the infirmary was cut off from the rest of the ship, trapping inside the Doctor and a young physician, Olivan. By that time, though, the Doctor had recovered, and together he and Olivan worked out a way to get out and contact the main deck, so that the Doctor was able to join the others for the final fight against Arran. When all was ended, he gave precious advice to the new leaders of the Last Borns before departing. (AUDIO: The Age of Endurance)

On the planet Malkus, the Doctor, Ian and Barbara got separated from Susan following an accident. Searching, they found her at the ruins of an empty military facility outside the city, where she and another man, Virgil Winters, had destroyed an evil plan of exploiting "gifted" people as weapons, as Susan's latent telepathic powers had been ignited by the atmosphere of Malkus. (AUDIO: E is for...)

Arriving on the planet Sarath in the city of Arkhaven, facing destruction as its moon descended towards the planet, the TARDIS crew were separated when a meteor strike hit the building the ship had landed on, resulting in the Doctor and Ian being taken to an NC2 camp while Susan was sent to hospital and Barbara was lost in the sewers. 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. (PROSE: City at World's End)

In another attempt to return Ian and Barbara home, the TARDIS malfunctioned, and they landed in a place filled with giant bugs and long, winding paths. Ian and Susan found a gigantic matchbox, while the Doctor and Barbara found a worm. Ian was trapped in the matchbox, which was taken by a man named Farrow, just as the Doctor realised that they were on Earth, but they had been shrunk down to the size of an inch.

Farrow met with Forester to tell him that his insecticide had been rejected, and was killed by Forester. The crew, looking for Ian, heard the gunshot and ran to the scene, where they were menaced by a cat. Entering the house, Barbara began to die when she touched the insecticide. She proceeded to contact someone through a telephone and reached Hilda Rowse and her husband Bert. They managed to grow back to size and Barbara recovered. Forester and his accomplice, Smithers, were handed over to the police. (TV: Planet of Giants)

Leaving Susan behind
With their size restored, the group arrived in the ruined 22nd century London. Splitting up to discover the cause of the devastation, Ian and the Doctor found that the Daleks had invaded. After learning about the invasion, the Doctor and Ian were rescued from the Dalek Earthforce and brought to the resistance. Heading south to Bedfordshire, the resistance discovered that Daleks intended to turn Earth into a warship. Turning this plan against the Daleks, the Doctor triggered a volcanic eruption that defeated them. Recognising that Susan had fallen in love with resistance fighter David Campbell and that (TV: The Dalek Invasion of Earth) she "needed to make [her] own way", (COMIC: The Forgotten) the Doctor reluctantly left her behind, promising to return, (TV: The Dalek Invasion of Earth) though he did not until his eighth incarnation. (PROSE: Legacy of the Daleks) He continued to question his decision for centuries to come, (COMIC: The Forgotten) and even slept through a materialisation because of his sorrow. (TV: The Rescue) Ian believed that locking Susan out of the TARDIS was the bravest thing that he ever saw the Doctor do. (AUDIO: The Revenants)

Shortly after leaving Susan in the 22nd century, the Doctor travelled to Venus to attend the funeral of Dharkhig, an old friend of his. There, the Doctor, Ian and Barbara became embroiled in the Venusians' conflict with their would-be saviours, the Sou(ou)shi. (PROSE: Venusian Lullaby)

Intending to give Susan a wedding ring, the Doctor, Ian and Barbara visited the mines of Alexandria. However, Ian was separated from the Doctor and Barbara, and Barbara accidentally created an alternative timeline after being sent nine years into the past. In the alternate world, King Ptolemy and his warriors went to war with the alien Rhakotis, and Barbara soon fell in love with Ptolemy and married him, becoming Queen. After nine years of war, the Doctor used a book from Gallifrey to repair time, erasing the alternative history and costing Barbara her husband. (PROSE: The Book of Shadows)

Returning to the planet Vortis, the Doctor, Ian and Barbara saved a pair of Menoptera from the Zarbi and their larvae gun by arrival of the TARDIS. (COMIC: On the Planet Vortis) The travellers were then confronted by the Zarbi, who captured the Doctor for his knowledge. However, the Doctor was saved when Ian and Barbara found Animus and killed the brain. Having saved the grateful Menoptera from the Zarbi menace, the three took their leave. (COMIC: The Zarbi Are Destroyed)

The TARDIS landed in a giant spider's web. The Doctor rescued Barbara when she became caught in it, and dematerialised just as the spider approached them. (COMIC: Dr. Who in the Spider's Web)

The Doctor and his friends visited the Aqua planet, where they became caught in the oceanpheric current and deposited in a patch of invisible liquid. Barbara was nearly eaten by an Aquamonster before the oceanphere moved, dropping the three back to dry land. (COMIC: Dr. Who on the Aqua Planet)

The Doctor arrived on Earth during the Ice Age, causing the TARDIS' controls to freeze. A monster picked up the TARDIS in its jaws, but its hot breath thawed the controls, allowing them to leave. (COMIC: The Ice-Age Monster)

The Doctor and his companions encountered Watermen from Q20, whose spaceship had broken down. The Doctor repaired the fault, allowing them to return home. (COMIC: Dr. Who Meets the Watermen)

The Doctor, Ian and Barbara returned to Skaro, where they were attacked by intelligent insects called Zomites. A group of Daleks arrived, killed the Zomites and allowed the Doctor and his companions to leave, warning them to never return to their planet again. (COMIC: The Daleks Destroy the Zomites)

The Doctor landed the TARDIS inside an air pocket at the bottom of the ocean. An Aquafein grabbed Barbara, but Ian shot it with a ray gun, causing it to release her. The arrival of more Aquafeins prompted their departure. (COMIC: Escape from the Aquafien)

The Doctor visited a planet where Ian discovered dozens of huge diamonds. The Doctor told him that there were so many that they were worthless, and that if they carried any into the TARDIS they would disappear. (COMIC: Where Diamonds Are Worthless)

The Doctor visited Earth during prehistoric times. A creature entered the TARDIS, but vanished when the Doctor moved the ship into a time when its species was extinct. (COMIC: The Prehistoric Monster)

The Doctor was paralysed by the Daleks' Nerve Machine. Ian used the telepathic helmet to reach the Doctor, who explained the situation. The Doctor was freed when Ian discovered the Machine and disabled it. (COMIC: Dr. Who and the Nerve Machine)

When asked by Barbara, the Doctor explained to her and Ian exactly how the TARDIS' large interior could fit inside its smaller exterior. (COMIC: The Secrets of the Tardis)

The Doctor and his companions hid from a group of Daleks that were searching for them. The Daleks tried to find them with their new Earthmen Detector, but instead they only discovered a cat and left. (COMIC: The Daleks Are Foiled) The Doctor and Ian rescued a scientist who had been captured by the Daleks and took him aboard the TARDIS. (COMIC: Rescued from the Daleks) On one planet, the Doctor watched Ian use a ray gun to destroy a Dalek, which caused the remaining Daleks to leave for home, but wondered if they would return. (COMIC: The Defeat of the Daleks)

The Doctor landed in the Orkney isles in 1956 thinking he could get Barbara and Ian back home. He didn't land fully when Ian and Barbara exited the TARDIS and he travelled further back in time. He waited for Ian and Barbara to catch up with him. (AUDIO: The Revenants)

The Doctor almost lost Ian and Barbara as companions when they considered settling down in 1950s Shoreditch, and he spent four months investigating the Stone of Scone in Scotland. Shortly after this, Ian and Barbara decided life in the 1950s would be too difficult and rejoined the Doctor aboard the TARDIS. (PROSE: Set in Stone)

The Doctor went on the trail of an energy being known as the Vrij and followed it to 1553 England, where he, Ian and Barbara met Queen of England, Jane Grey. Defeating the Vril, who had possessed the Duke of Northumberland, the Doctor resisted the urge to alter Jane's fate and instead stayed by her side as she died. (PROSE: The Nine-Day Queen)

The Doctor had another encounter with River Song during his travels with Ian and Barbara. Because he spent his time "hanging out with the two teachers", River considered the First Doctor to be "boring". River wiped his memory with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)

Joined by Vicki
Still struggling to adapt to life without Susan, the Doctor, Ian and Barbara ended up on Dido, where they met two survivors of a crashed spaceship, Vicki Pallister and Bennett, and learnt a being called Koquillion had embarked on a reign of terror, leaving those who survived his wraith greatly fearful of him. However, the Doctor soon discovered Bennett was actually Koquillion after he caused the crash when he was unmasked as a killer to prevent the crew from radioing back to Earth. He killed the crew, many Dido natives, but spared Vicki so she would back up his story when the rescue crew came to collect them. Just as Bennett prepared to kill the Doctor, two Dido natives saved him and forced Bennett to his death. With all of her associates dead, Vicki joined the Doctor in the TARDIS, providing him with a new youngster to care for as had been the case with Susan. (TV: The Rescue)

Immediately following their departure from Dido, the TARDIS landed in 64 AD in the area just beyond the great metropolis Byzantium. Despite the Doctor's resignation from visiting the Roman Empire, the group made their way to the city. After a week in Byzantium, the group prepared to go back to the TARDIS, but were instead caught up in a large Jewish revolt in the market-square, separating them. At least two weeks passed before the group was brought together again, but then the TARDIS was missing, and the group joined a travelling caravan moving towards Rome, in hopes of finding the TARDIS along the way. (PROSE: Byzantium!)

Arriving near Rome, the Doctor and Vicki came across a Roman villa, where they found the caretaker, Lucius, wounded after being attacked by a lion. Shortly before his death, Lucius allowed them to stay in the villa in his master's absence, where they managed to kill the lion that attacked Lucius. (PROSE: Romans Cutaway) Having found the TARDIS and spent several weeks relaxing at the villa, the Doctor and Vicki decided to visit Rome. However, on the way, the Doctor was mistaken for famous lyre player Maximus Pettulian and was taken to meet Emperor Nero. While at the palace, the Doctor discovered that prior to his death, Maximus was involved in a conspiracy to kill Nero, but was assassinated by Ascaris. After bluffing his way through a performance on the lyre, the Doctor inadvertently gave Nero the idea to start the Great Fire of Rome when the light reflected through his glasses caused some maps of Nero's plans for a new Rome the Senate rejected to catch fire. (TV: The Romans)

After a quick visit to early 20th Century Earth, the Doctor helped on a world where the Waneshi invaded. (AUDIO: Starborn)

On Aridius, the Doctor discovered via the Time-Space Visualiser that the Daleks were on his trail to kill him and take the TARDIS, and that they were already on Aridius as the visualisation was in the past. After saving Ian and Vicki from a Mire Beast, the Doctor and his companions escaped Aridius as the Daleks began slaughtering the Aridians workforce. With the Daleks in hot pursuit in their time vessel, the Doctor went to many different times and places to shake them off, including the Empire State Building in 1966 and the sailing ship Mary Celeste. They accidentally left Vicki behind at the Festival of Ghana in 1996, but she stowed away on the Daleks' time ship and followed the TARDIS to Mechanus.

There, the Daleks created an android version of the Doctor, which Ian believed to be the Doctor and ended up fighting the real Doctor as he thought he was the fake until the Dalek-controlled Doctor addressed Vicki as Susan.

Travels with Steven and Vicki
Shortly after bidding farewell to Ian and Barbara, the Doctor and Vicki were shocked to find Steven aboard the TARDIS as the ship landed in 1066 Northumbria. To his great dismay, the Doctor discovered another member of his race, the First Monk, was scheming to alter history by luring and destroying a Viking fleet with an atomic cannon, which would result in King Harold Godwinson winning the Battle of Hastings. After the Monk was driven out of his monastery by Saxons, the Doctor infiltrated the Monk's TARDIS and stole the dimensional control. When the Monk tried to take off after his plans failed, the interior of his TARDIS began to shrink beyond use, trapping him in 1066. (TV: The Time Meddler)

The TARDIS crew met Xenith, a city-sized sentient computer. (COMIC: Are You Listening?)

The TARDIS travellers went to London in 1814, during the last Frost Fair, where they met Jane Austen and, with her assistance, tried to prevent a Phoenix's egg from hatching; if it did, the creature would absorb all the heat on Earth, condemning it to extinction. The Phoenix possessed Lady Georgiana, the wife of the Deputy Warden of the Royal Mint Sir Joseph Mallard, and with her help tried to enter the building, hoping that the heat of the furnace would be enough to hatch the egg. After tracing the egg, the Doctor offered the Phoenix to take it somewhere else, on a planet yet to be born, so that it could still live without endangering anyone. When the Phoenix refused, the Doctor and his companions stopped the furnace from working and let its fire die so that the Phoenix could die too. (AUDIO: Frostfire)

The Doctor attempted to increase the inhabitable space of the TARDIS using the dimensional control he stole from the Monk, but the experiment went wrong and he had to abandon the TARDIS.

Whilst in the pods, he heard a voice that wanted to kill him. The Doctor worked out using the data Vicki had collected for him that Thorn was behind the mysterious happenings on Ceres. (AUDIO: The Bounty of Ceres)

The First Doctor was pulled out of his time by the Time Lords, who wanted his help in getting the Second Doctor and the Third Doctor to work together to stop Omega, but he became trapped in a time eddy and had to advise his succeeding incarnations from afar, though he succeeded in getting them to cooperate. Once his successors solved the crisis, the First Doctor was returned to his proper place in time, (TV: The Three Doctors) with his memories wiped to preserve the timeline.

The Doctor waited for Vicki and Steven when they ran from the Antoim who were shooting at them. However, his fifth incarnation took his place and was forced to act as the First Doctor would have to protect the timeline when they visited Ravenna, Italy, 540. The Monk had been behind the displacement in the Doctor's timeline. The Monk located Sophia, a time-sensitive Human/Hetrodon hybrid in ancient Greece and used her abilities to create a hole in space-time, which the Monk planned to use to take the Doctor's place in history after being deeply affected by the death of Tamsin Drew.

Fighting the Daleks
The Doctor landed the TARDIS on the planet Kembel in the hopes of finding medicine for Steven's blood poisoning, leaving Steven in the TARDIS with Katarina. There, he encountered Bret Vyon, a Space Security Agent who wanted to steal the Doctor's ship, and was knocked out and had his keys stolen. As Bret tried to get Katarina to pilot the TARDIS, Steven knocked him out and let the Doctor in. After securing Bret to a chair, the Doctor went outside again, where he heard a spaceship landing, and decided to head towards it in search of the needed medicine, only to learn that it was a Dalek saucer.

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, informed the Doctor that the Daleks had started to burn down the jungle. With the Doctor resolved to find out what the Daleks were doing on Kembel and stop them, he and the others discovered a large landing bay with ships from the many outer galaxies and the 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' Time Destructor. However, the Doctor stole the Taranium and ran off before the meeting was concluded. Having only just managed to get aboard the Spar in time before Bret and the others blasted off, the Doctor learned of the Daleks' plans by listening to a tape he had retrieved with a message from Marc Cory, another SSS Agent and associate of Bret's.

The Doctor and Bret agreed to head back to Earth and warn the authorities of the Dalek threat. However, the Daleks seized control of the Spar and forced it to crash-land on the planet Desperus, where convicted criminals were sent. 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. 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. However, Katarina opened the outer door of the ship, sending Kirksen and herself to their deaths in the vacuum of space. Shaken, the Doctor lamented that, while Katarina couldn't have understood what she was doing, he would always remember her as "one of the daughters of the gods".

After landing on Earth, the Doctor, Steven and Bret 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 him. 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.

Evading capture, the Doctor and Steven were pursued by Sara into an empty chamber were they all fell victim to a molecular dissemination experiment and were transmitted to the swampy planet Mira. A small Dalek task force soon arrived on Mira to apprehend the travellers and regain the Taranium. After the Doctor found Steven and Sara, they made their way to a nearby cave for shelter and tried to persuade Sara about the Daleks' plot with Mavic Chen, with Steven also furious with Sara for killing Bret, who Sara admitted was her brother. Suddenly, the invisible inhabitants of Mira, the Visians, surrounded the cave, but a Dalek appeared and shot one of them dead, causing the other Visians to begin attacking the Daleks and, in the confusion, the travellers evaded capture, stole the Daleks' spaceship and escaped Mira. Upon their return to Kembel, the Doctor gave the Daleks a copy of the Taranium Core he had made on the way, and 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)

Resuming their travels, 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 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 him to Mars so that he could see something incredible before his death. (PROSE: The Little Drummer Boy)

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

When the TARDIS was dragged inside the Great Clock, the Doctor was intrigued by its functioning, and insisted on going to explore. He, Steven and Sara saw the old men toiling inside the Clock, but, as they were trying to figure out what they were doing, they were captured by Space Security Service agents. The agents recognised Sara as one of their own, and took her to meet a superior officer for questioning. The Doctor and Steven managed to escape from their cell, and found a deserted monitor, which they used to search for information about their whereabouts. They discovered that they had landed in 3999, one year before their meeting with Sara, that Bret Vyon was the officer Sara had been brought to, and that Mavic Chen was there too. Steven proposed to go looking for Sara, but the Doctor stopped him, as them being spotted by Chen and Bret could have disastrous consequences for the future. Instead, they went back to the Clock to sabotage it and escape in the confusion. However, they ended up being trapped inside it, since the machine fed on the hope of escape of its prisoners and their efforts to find a weak link in its construction. They were freed by Sara when she managed to destroy the Clock. (AUDIO: The Guardian of the Solar System)

On their travels, the TARDIS landed on a planet covered in water, where they found a set of miners in a collapsed mine. They were attacked by a tentacled creature, but Sara and the Doctor were able to reason with it. (AUDIO: The Drowned World) 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. The Doctor wanted to investigate, but Steven got annoyed when he couldn't find a way to get out of the house. (AUDIO: Home Truths)

The TARDIS later crashlanded in 1950s London, as a result of the psychic attack by a race of anemone changelings. Because of his bond with the ship, the Doctor fell into a coma as Steven and Sara brought him out, moments before the TARDIS locked itself as a defence mechanism, though he was conscious and aware of his surroundings. Steven and Sara were given shelter by Joseph Roberts, a Jamaican immigrant, and his nephews, Michael and Audrey Newman, but Michael was actually a changeling duplicate, and kidnapped the Doctor and the TARDIS. The changelings intended to use the TARDIS as a source of psychic energy for their morphing abilities, but deemed the Doctor unimportant their plans. As he gathered information about them during his imprisonment the Doctor finally awakened after two-weeks in his coma and, by Steven's intervention, reached Sara, explaining to her how to stop the changelings and shielded her presence so that she could reach their hideout undisturbed. (AUDIO: An Ordinary Life)

Attempting to rest on an asteroid, 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 the TARDIS, and thought it might be the Daleks pursuing them. After briefly materialising in the Oval during a cricket match, the TARDIS landed on Tigus, where the Monk, seeking revenge for being stranded in 1066, sabotaged the TARDIS lock, stranding the Doctor and his companions. However, the Doctor quickly fixed the problem and departed, with the Monk following close behind.

After briefly materialising in Trafalgar Square during the New Year's Eve night of 1966, the TARDIS landed near a pyramid in ancient Egypt. 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. (TV: The Daleks' Master Plan)

Joined by 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 took Oliver and Steven to Grace Alone after 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
Knowing he was nearing his first regeneration, (PROSE: The Five Doctors) the Doctor visited his rose garden for some peace and contemplation, while Steven rested in the TARDIS. As he tried to look for ways of rectifying his relationship with Steven, (PROSE: Roses) the Doctor was taken by a Time scoop to the Death Zone, where he was reunited with Susan in a tower.

(PROSE: A Simple Truth)

Reaching the Tomb of Rassilon, the First Doctor joined with his second and third incarnations to study the writing on Rassilon's tomb, and open the teleportation systems. The Fifth Doctor arrived, under the control of Lord Borusa, who had brought the Doctors there to help him retrieve immortality from Rassilon. The combined concentration of the three Doctors, however, was enough to break Borusa's control over their future incarnation. When Borusa spoke to Rassilon and took his offer of immortality, the First Doctor 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. The Doctor then left with Susan as he was returned to his time zone by Rassilon. (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.

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)

Shortly afterwards, the Doctor came to the assistance of the Daleks when their own creation, the machine brain, turned against them. He deactivated the machine, and the Daleks held a banquet in his honour. (PROSE: Doctor Who and the Daleks)

John and Gillian
Going by the name "Dr. Who", the Doctor once more landed the TARDIS in an empty yard in 1960s England, where it was found by his grandchildren, John and Gillian Who, who had been looking for their grandfather. They did not know him personally, but had been told he was "an inventor of some sort".

He told them to use the moon's reduced gravity to jump out of the chasm, which resulted in them being freed. (COMIC: Moon Landing) After landing on an island, the Doctor and his grandchildren lost the TARDIS in the sea. Rescued by a tribe and forced to join their camp, they discovered that time was going backwards due to a fault in the TARDIS.

(COMIC: Time in Reverse) On a visit to another alien planet, the Doctor once again lost the TARDIS when it was taken by a giant lizard, but he retrieved it by hypnotising the lizards to sleep. (COMIC: Lizardworld)

(COMIC: Prisoners of the Kleptons)

The Doctor visited a jungle on Earth in 2035, where he was captured by Caterpillar Men and held prisoner in their base with other scientists.

Resumed travels with Steven
The Doctor and Steven stopped an alien invader on a nearby beach with the help of Greenaway, who lost his legs and part of his skull in the incident, and ended up in a coma.

The Doctor and Steven used a helicopter to fight a giant mosquito, with the Doctor destroying the creature with washing up liquid. (PROSE: Do You Smell Carrots?)

Arriving in a forest on Christmas Eve, the Doctor and Steven discovered a family forced for generations to care for alien trees. Learning the trees had taken one member of the family who hadn’t believed his father’s warnings, the Doctor berated the trees for taking advantage of the family, convincing them to release him. With a more amicable relationship between the family and trees established, the Doctor and Steven left to celebrate Christmas themselves. (AUDIO: O Tannenbaum)

Steven and the Doctor once again met the Vardans in the connection between Earth and the Mediosphere when they came up with the idea of using comedy television to spread a virus that would kill humans with laughter after studying radio frequencies from Earth in order to conquer the planet. However, a comedian, Teddy Baxter, and his straight man, Stan, perceived them while observing the stars. The Vardans managed to pull Stan into the Mediosphere, but were unable to do the same with Teddy.

While the Doctor and the TARDIS were absorbed into the Mediosphere, Steven was stranded in 1950s London. When the Vardans brought Steven and Teddy to their spaceship, they tried to absorb Teddy as well, but made the mistake of showing Teddy a possible future. This made it impossible for them to kill him, since, as the Doctor explained, once the future had been made real, it became a fixed point in time, and if the Vardans killed Teddy, this would trap them into a time bubble. Steven and the Doctor then helped Teddy to defeat the Vardans, chasing them from Earth, before bringing him back to Earth in the TARDIS. (AUDIO: The Vardan Invasion of Mirth)

Meeting Dodo
The Doctor and Steven arrived in Paris in 1572, where the Doctor 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 decided to leave 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)

The TARDIS took them to New York City in 1965, 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, and 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)

Travels with Steven and Dodo
Together, the TARDIS crew encountered humans and Monoids from the far future, which were fleeing the doomed planet Earth to Refusis II on a spaceship which Dodo nicknamed the Ark. The Doctor aided the crew against an outbreak of the common cold, but upon returning to the Ark seven hundred years later, he discovered that the Monoids had taken over and were planning to kill the humans. With the aid of a Refusian, the Doctor saved the humans. (TV: The Ark)

The TARDIS was then captured by the Celestial Toymaker, who turned the Doctor invisible and forced him to play the Trilogic game, while Steven and Dodo were forced to play against the Toymaker's pawns.

The Doctor, Steven and Dodo settled down in 1812 Russia for a while, where the Doctor became the tutor for a local gentry's children, though he still wished to leave the country before Napoléon Bonaparte invaded. Before Napoléon arrived, however, the Doctor was attacked by a shape thief who took his form, but he caused the thief's downfall by convincing him that Napoléon was going to win and tricked him into taking Napoléon's form. (AUDIO: Mother Russia)

On Bukol, the First Doctor got caught up in his sixth incarnation's attempt to protect shape-shifters Orsa and Alëza from the assassin Mykloz, with the First Doctor being arrested due to Orsa and Alëza taking on Steven and Dodo's forms and labelling him an impostor, but he was able to clear his name with the aid of his old friend Anu-Ak.

The Doctor, Steven and Dodo met Questor in the living jungle of Tropicalus, whom the Doctor defeated in a battle of wits, (COMIC: Death to the Doctor!) and investigated a crashed spaceship at the Battle of Spion Kop during the Boer Wars, where they witnessed Tommy Watkins apparently destroy Kali Carash, but the Doctor remained unconvinced of Kali Carash's defeat. (AUDIO: Tales from the Vault) On Vortis, the Doctor became separated from Steven and Dodo and saved a platoon of Sontarans from a Rutan infiltrator. (PROSE: The Dream)

On the planet Comfort, the TARDIS arrived in the middle of a war. The Doctor realised that the inhabitants were brainwashed into boldly following orders. The locals took him to their leader when they realised he wasn't local. He was able to use his status as an outsider to end the staged conflict that was part of the system on Comfort by identifying himself as the leader of the enemy forces, despite the fact that the "enemy" were the same population wearing different uniforms, and end the war by declaring his "surrender". (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 civilised lifestyle, but their intelligence was gained by draining the life energy from the Savages. The Doctor stopped this practice with the aid of a group of Savages by destroying the laboratory and equipment that transferred energy from the Savages and left Steven behind to keep the peace between the two groups for the future. (TV: The Savages)

Exploits with Dodo
The Doctor and Dodo visited Scrabster Harbour in 1947, (AUDIO: Masters of Earth) travelled aboard the Golden Hind, (AUDIO: Maker of Demons) and visited New Houston, where they were helped by Meg Carvossa in stopping an alien invasion. 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. By this point, the Doctor's physical strength was beginning to leave him as his first regeneration approached. (PROSE: The Man in the Velvet Mask) However, he resisted the process and held back the change. (PROSE: Twice Upon a Time)

Sometime later, the Doctor managed to return Dodo to London in her own time. There, the Doctor noticed the new Post Office Tower and felt compelled to investigate the building. Inside, he discovered a new supercomputer called WOTAN, which had become sentient. It gained mental control of its creator and several others, including Dodo, and forced them to create mobile War Machines to take over London. Having almost been taken over himself, the Doctor discovered Dodo's true motives and put her to sleep with hypnotism. With the Army being called in by Sir Charles Summer, there was an unsuccessful raid on a Covent Garden warehouse and the War Machines attacked. However, the Doctor managed to stare down the machine and it backed down. The Doctor was then able to reprogram the machine to attack and destroy WOTAN, which it duly did. (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) His retirement was eventually ended. (PROSE: The Meeting)

While visiting a planet, the Doctor witnessed the poisoning of Princess Clio on her fifth birthday, and had her placed in a stasis bed to keep her alive, though comatosed. Because the bed required a lot of power to activate and deactivate, it was decided to only awaken Clio briefly for her birthday each year, with the Doctor giving her a brooch as a gift. (PROSE: The Glass Princess)

The First Doctor hosted a Christmas dinner with his seven successors. (PROSE: The Feast of Seven... Eight (and Nine))

The First Doctor was taken out of time by the Tenth Doctor, who brought him and the Second Doctor to the planet Henlen, where their third, fourth, fifth, sixth, seventh and eighth incarnations were trying to correct the temporal paradox caused by the Sirens of Time when they sabotaged the first Gallifreyan experiment for time travel. While the others piloted the TARDIS prototype used in the experiment, the First Doctor remained with his second and tenth incarnations to make sure the backlash from their operation did not aggravate things. (AUDIO: Collision Course)

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.

(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.

(PROSE: Please Shut the Gate)

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

While Ben and Polly were visiting an old friend, the Doctor was gifted a golden bow by the Emperor of Gallutia for convincing his enemies into a surrender. Travelling to medieval England to have some archery practice, the Doctor saved Lady Mary from bandits and brought her into the TARDIS, but was prevented from entering himself by knights in armour, who mistook him for a kidnapper and a wizard. Afraid of his powers, the knights tried to kill the Doctor, but he escaped to a castle and locked himself inside as the knights and their reinforcements arrived. With his arm injured, the Doctor summoned his second, third, fifth and sixth incarnations to rescue him. After the Fifth Doctor lost the game that chose who would face the knights, he explained the situation to them and the Doctors were permitted to leave when he also gave them the golden bow as a peace offering. (PROSE: Five Card Draw)

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)

The TARDIS was involved in an accident which knocked out the Doctor and injured Polly. His injuries were severe according to Continuity. Continuity later swapped the Doctor's mind into Polly's as part of the "cure". The Doctor learnt that the computer was maliciously killing every patient as it thought they were damaging the universe. He realised that the time skips where caused by the destruction of the hospital and made it happen as it was predetermined to do. (AUDIO: The Crumbling Magician)

While dealing with a telepathic plague in the 16th 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 that 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 fulfil his destiny and go to the South Pole so that history could unfold as it should. (AUDIO: The Plague of Dreams)

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)

After Ben and Polly awoke, 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)

Last stand at Snowcap base
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. (TV: The Tenth Planet) Knowing the Cyberman invasion would ultimately be resolved through his reading of historical accounts, the Doctor was content to be an observer, though remained ready to intervene should the situation call for it. (PROSE: Twice Upon a Time) However, he collapsed when Mondas began draining Earth's energies, (TV: The Tenth Planet) due to his regeneration process starting, (PROSE: Interference - Book Two) and Mondas syphoning off his ability to resist regenerating any longer. (PROSE: Twice Upon a Time)

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. (TV: The Tenth Planet)

Walking in the snow, the Doctor caught a fading image of 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) using the fast return switch. (PROSE: Twice Upon a Time) As the TARDIS' controls continued to operate on their own, the Doctor 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
Because of a trick in his Gallifreyan optics, (AUDIO: The Power of the Daleks) the Second Doctor saw his first incarnation in his reflection while still adjusting to his new body after his first regeneration. (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)

In a bid to detach the Funhouse from the TARDIS in the time vortex, the Sixth Doctor binded the switch that protected the TARDIS' passengers from the changing time fields outside with a string, allowing him to pull it remotely from the limited protection of the Zero Room. As a result, the Doctor immediately began to regress back through his first five incarnations as he made his way back to the console room where, as the First Doctor, he flipped the switch back, restoring himself while trapping the Funhouse in the vortex. (COMIC: Funhouse)

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, including the First Doctor, were created instead. (COMIC: Breakfast at Tyranny's)

After the Eleventh Doctor was accused of committing deadly crimes against the Overcast, he brooded in the TARDIS for two days, imagining all his previous numbered incarnations, including the 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)

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 of Gallifrey 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, eventually becoming Lord President and forming an alliance with the Dalek Empire. The Seventh Doctor, Bernice Summerfield 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 created when an exiled Rassilon allied with the Cyberiad to conquer all of history, (COMIC: Supremacy of the Cybermen) three Mondasian Cybermen captured the First Doctor at 76 Totter's Lane on Earth in 1963, on the day that he was supposed to leave Earth with Susan Foreman, Ian Chesterton and Barbara Wright. (COMIC: Prologue: the First Doctor) This timeline was ultimately erased when, on Gallifrey at the end of the universe, the Twelfth Doctor and a betrayed Rassilon used the harvested regeneration energy stored in the Eye of Harmony to restore the original timeline via the Cyberiad's dominance across all of history. (COMIC: Supremacy of the Cybermen)

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, by having her original self to suggest her grandfather to shut down the defence systems of the ship. (AUDIO: Tick-Tock World)

In a negated timeline, the TARDIS was attacked on 23 November 1963 by a conceptual bomb bought by and began to be erased from time. The First Doctor, along with his second and third incarnations, became trapped in another dimension, and tried to warn their other incarnations by reducing the explosion to a blinking light on the TARDIS with the coordinates of the explosion. However, when their four successors followed the warning, the Master took direct action in attacking them, until the Sixth Doctor managed to bring them together to formulate a plan. After the Fifth Doctor ensured that the TARDIS would not explode, the Doctors prepared to time ram the Master's TARDIS. However, rather than kill the Master, the First Doctor instead turned off the automatic distress actions, making it so none of the Doctors followed it into the explosion and undoing the events of the day. (AUDIO: The Light at the End)

After departing Troy with Steven Taylor and Katarina, the TARDIS collided with its future self and landed on Urbinia. The Doctor settled on the planet for three months among the scientific community, delivering lectures while hoping to fix the TARDIS's circuits. In his absence, however, the Daleks developed the Time Destructor and attacked the planet. The Doctor effectively took charge of the evacuation, but came into conflict with his second incarnation, who warned him that Katarina had to die to prevent the Dalek conquest. The First Doctor was ultimately captured by the Daleks, but the Second Doctor flung his TARDIS back into the heart of the initial collision, preventing it. The First Doctor arrived on Kembel and the timeline was reset. (AUDIO: Daughter of the Gods)

Personality
In his older 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) even believing himself superior to those he saw as intellectually inferior. (COMIC: A Religious Experience) 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) His ego persisted however with him telling white lies to inflate his own self-importance, (PROSE: Twice Upon a Time) and his false modesty at being heralded by the Thals when he visited their city. (AUDIO: Return to Skaro)

In his youth, the Doctor believed that it was impossible to "diminish wonder, beauty and discovery," even when people tried to take the mystery out of things. (PROSE: Longest Day) The Doctor never felt at home on Gallifrey. (AUDIO: No Place Like Home) 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) but told Susan that "individuals hungry for power" were to be fought, and that "the right thing to do was often forbidden". (COMIC: Time & Time Again)

During his early travels, the Doctor rarely smiled, (PROSE: Dr. First) although, when he first witnessed the French Revolution, the Doctor's emotions were swept up in the revolutionary fervour and optimism as the French population around him rose up against their rulers. (PROSE: Just War) Beyond this, he remained 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) Despite this, the Doctor was mostly self-serving, even locking fleeing people out of Coal Hill School to better protect himself from the Space wolves. (PROSE: Doctor Who and the Horror of Coal Hill)

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) When on Destination, he had planned to skip ahead several years instead of helping the colonists only for Susan to refuse to join him in such an act, convincing him to stay and help. (AUDIO: The Destination Wars)

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 helped shape 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 the First Monk 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) He thought that forging alliances between factions was reward enough for his travels and efforts. (COMIC: Mission for Duh)

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) and kept brandy in his TARDIS. (TV: Twice Upon a Time) He held a passion for fifth dynasty Aquilian architecture, (PROSE: The Golden Door) and liked chocolate ice cream, (PROSE: Bide-a-Wee) but "loathed" recorders. (AUDIO: The Power of the Daleks) He also disliked hippies and pop music. (PROSE: Dr. First)

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) believing that "nothing [was] impossible". (PROSE: The Nine-Day Queen) He once questioned if saving an entire planet of people was more important than saving an individual life. (PROSE: Venusian Lullaby)

The First Doctor believed that evil "[didn't] follow principle", and that "the greatest evil [was] inaction", with rules "just [being] distractions". He thought that the best way to combat evils was with kindness and understanding. (PROSE: A Simple Truth)

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 tried to convince King Richard to carry out his peace plan. (TV: The Crusade) However, when he first challenged the First Monk, the Doctor quickly labelled him a "time meddler" and quickly continued to uphold his belief that history could not be changed. (TV: "Checkmate") He 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) In some cases, even when the Web of Time was in potential danger, he preferred to "watch and wait", trusting that time would sort itself out in the end. (AUDIO: Daybreak) However, he would interfere if he believed the effect to time would be minuscule, (COMIC: Unnatural Selection) and, 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 could be dismissive towards casual violence. (PROSE: Tarnished Image)

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) While combating Adam Mitchell's Autons, the First Doctor associated himself with his second and seventh incarnations, combining with them to think of a solution to the situation. (COMIC: Endgame) However, he disliked his seventh incarnation, believing him to be "too manipulative". (PROSE: Five Card Draw) Upon meeting his tenth incarnation, the First Doctor took a disliking to him and his behaviour. (AUDIO: Collision Course)

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 did not like him at first, 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) Despite his love for his granddaughter, however, he could come across as condescending towards her, refusing to tolerate her ideas and treating her like a child. After meeting a future version of Susan, one who had little love left for him, he began making an effort to change this attitude. (AUDIO: Tick-Tock World) 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) Dodo Chaplet implied that she thought the First Doctor to be "condescending, arrogant, smug and irritating". (PROSE: Tarnished Image)

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)

While found him admirable for his intelligence, he also admitted that the First Doctor was a "bore", (GAME: Destiny of the Doctors) with Adam Mitchell identifying the First Doctor as the "educator" in comparison to his other incarnations. (COMIC: Unnatural Selection)

While some of his later incarnations would speak highly of the Master, (TV: The End of Time, World Enough and Time) the First Doctor had a very low opinion of his once friend, dismissing him as a charlatan and taking great pleasure in outsmarting him. (AUDIO: The Destination Wars)

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 the First Monk originated on the same world. (TV: "Checkmate")

The Doctor was very particular about how others addressed him; he never liked how the Second Drax called him "Theta Sigma", (PROSE: Divided Loyalties) 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. However, he wasn't confident in his ability to pilot it after initially taking off from Antarctica and was amazed by his future incarnation's ability to flawlessly pilot the TARDIS to Villengard. (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 a talented lock picker. (PROSE: The Nine-Day Queen)

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)

The First Doctor could suppress strong bouts of pain though sheer willpower. (PROSE: A Big Hand for the Doctor)

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) One account implied that the First Doctor's body was prematurely aged by too many different gravities and too many "close encounters with death". (PROSE: Prisoners of the Sun)

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) According to his war incarnation, the First Doctor was colour-blind. (PROSE: The Day of the Doctor)

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) A waiter once described the First Doctor as the "little old man with the long grey hair". (PROSE: The Meeting)

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 Fourth Doctor, when reflecting on his change of appearance after his first regeneration, called the First Doctor a "distinguished white-haired gentleman". (AUDIO: The Power of the Daleks)

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)

As the First Doctor resisted regeneration, the Twelfth Doctor noted a slight change in his appearance as a result of the "state of grace" the First Doctor was existing in. (TV: Twice Upon a Time)

Main attires
Making his fashion decisions with a computer to better blend in with modern society, (PROSE: A Big Hand for the Doctor) the First Doctor affected a slightly eccentric Edwardian dress sense, wearing a double breasted town coat of ebony black velvet with a shawl collar, a beige tweed waistcoat over a white shirt with a royal blue 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 ascot tie with ivory stripes 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 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) shared a few glasses of Médoc with John Lucarotti (PROSE: The Meeting) and told Steven that he fancied chilled white wine in France. (PROSE: The Massacre)

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: AUDIO: Auld Mortality and AUDIO: 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 the same episode, as the First Doctor is seen walking past the real Clara, Hurndall is the one seen. 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.

The Doctor Who Fun Book
On top of a few "serious" stories about the Doctor, such as the comic stories The Test of Time, the 1987 Doctor Who Fun Book also contained a number of media not considered valid by this Wiki either because of their format or of their parodical nature. The First Doctor was featured in one of the parodical comics, where he was shown having a picnic on Vortis with Ian, Susan and Barbara, only for the classic "ants at the picnic" problem to rear its gigantic head in the form of the Zarbi.

More interestingly, a rare glimpse into the Doctor's life on Gallifrey is provided by the short story NOTVALID: TARDIS Stolen!. There, following the Doctor's theft of the TARDIS and flight from Gallifrey, the Gallifrey Gazette investigates the thief's background. He is stated to have graduated in Music and Performing Arts from the Academy, even starring in an Academy performance of The Army Game, and to be currently going by the alias of "Doctor Wat Who" on Gallifrey; other aliases past and future of the Doctor are mentioned as "Doctor Spock, Mister Mann and Terry McNation". He is described as "a young man in his early centuries", with Susan Foreman stated to be 98 years old.

Doctor Who: Legacy
In the story of Doctor Who: Legacy, the First Doctor witnesses the damage to time caused by the Sontarans' attacks throughout history from his TARDIS control room before seeing Sontar overrun by "metal spheres", the Toclafane. He then joins his other selves and their companions as they travel through time to repair the damage.
