User:BananaClownMan/Sandbox/Third Doctor

Forced into an exile on Earth in the 20th century by the Time Lords, with his TARDIS rendered inoperable, the Third Doctor was a distinguished man of high class and gadgetry, often tinkering away with contraptions or working on his prized car, Bessie, when he was not assisting Brigadier Alistair Gordon Lethbridge-Stewart and his UNIT troops Sergeant John Benton and Captain Mike Yates in their fight against invading aliens, working with them as their scientific advisor, initially alongside Dr. Liz Shaw, until she decided to return to the University of Cambridge to pursue her own work. The Doctor often took exception to the Brigadier's military approach, especially concerning the outcome of the Wenley Moor Affair, just as the Brigadier was frequently irritated by the Doctor's air of superiority and seeming disregard for authority, but they ultimately developed an easy mutual trust and strong friendship.

Following Liz's departure, the Doctor was given a new assistant named Jo Grant, who was as bubbly as she unscientifically trained, but he developed a great fondness for her. No sooner had Jo arrived that the Third Doctor became entangled in an ongoing battle of wits against the Twelfth Master, who also became stranded on Earth when the Doctor stole the dematerialisation circuit from the Master's TARDIS in an attempt to fix his own, until he was forced to return it during the Stangmoor Incident. However, the Master's attempt to ally with Axos forced him to ally with the Doctor, allowing him to trick his two foes into partially repairing his TARDIS, though with him stuck as a "galactic yo-yo" that would always have to return to his exile.

After the Master was finally arrested by UNIT following his failure to ally with the Dæmon Azal at Devil's End, the Doctor found himself pushing the limits of exile as he travelled to an alternate future ruled by Daleks, visited Peladon for the first time, and was even recruited by the Time Lords for a mission on 30th century Solos. After the Master escaped his imprisonment with aid from the Sea Devils, the Doctor and Jo ended up chasing him to Ancient Atlantis, where they stopped him harnessing the power of Kronos the Chronovore, though the Doctor allowed him to escape.

The Doctor's exile finally came to an end when the Time Lords united him with his first and second incarnations in the First Omega Crisis, with the Doctors' defeat of Omega in the anti-matter universe being rewarded with the Time Lords restoring the TARDIS to full working order. The Doctor tried to celebrate his new freedom by taking Jo to Metebelis III, but they ended up getting side-tracked by misadventures like the Daleks' Spiridon campaign. Eventually, Jo became homesick, and a return trip to Earth saw her leave the TARDIS to marry scientist Clifford Jones after meeting him at Llanfairfach while the Doctor was on Metebelis III. The Doctor gave her a Metebelis crystal as a wedding gift.

The Doctor would then adventure alone for some time, until he met journalist Sarah Jane Smith while saving UNIT associated scientist kidnapped to the 13th century by the Sontaran Linx. While she first tried to leave his company due to initially being an accidental stowaway, her aid to him during Operation Golden Age, which saw Yates betray UNIT due to his political beliefs, encouraged them to continue to travel together, visiting planets such as Exxilon, Florana and Peladon.

However, the Doctor's adventures came to an end when the Metebelis crystal was returned to him, heralding an invasion by the Eight Legs of Metebelis III to reclaim the crystal. With the aid of Sarah and a repentant Yates, the Doctor was encouraged by his childhood mentor to face the Eight Legs' Great One in the caves of Metebelis III to thwart their invasion, where he received a lethal dose of radiation as he escaped the cave's destruction in the TARDIS. The Doctor would be stuck wandering around the Time Vortex until the TARDIS "brought [him] home" to UNIT, where he managed to regenerate into a younger body.

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

After he was returned to his timeline from assisting his two successors with Omega, (TV: The Three Doctors) the First Doctor had only vague memories of the experiences, remembering only "a dandy and a clown". (PROSE: The Empire of Glass)

When the First Doctor learned that he was diverted from the South Pole by "forces from the future" to stop him from becoming an incarnation that would play a key role in a future conflict, he was informed by the Player that the incarnation in the conflict would not be his second or third incarnations. (AUDIO: The Plague of Dreams)

The First Doctor was shown footage of the Third Doctor, as well as his ten other successors, by the Testimony when he expressed doubt over the Twelfth Doctor's identity. (TV: Twice Upon a Time)

After being shot through the head, and injured during the subsequent fall off a walkway, the Second Doctor began to regenerate, but the process was halted by the Shiner tissue injected into him by the SILOET doctors, causing him to enter a six month coma to heal his body without regenerating. (PROSE: The Indestructible Man)

After teaming up with his third incarnation against Omega, (TV: The Three Doctors) the Second Doctor recalled how he "[met] [him]self with another face", (POEM: Goodbyes) and how his "replacement" was "unpromising", (TV: The Five Doctors) as well as that he had promised to replace his recorder. (WC: Doctors Assemble!)

After his struggle with the War Lords, the Second Doctor was sentenced by the Time Lords to a forced regeneration and Exile on Earth in the 20th century, where he would be allowed to help protect the Earth, with his knowledge of TARDIS operation blocked. Though he was given the chance to pick his next appearance, the Doctor rejected his options, so the Time Lords decided to pick for him. (TV: The War Games) However, the Celestial Intervention Agency interceded with the sentence, turning the Doctor into their "hired gun". (PROSE: World Game)

Eventually, the Doctor's sentence of exile to Earth was enforced, (COMIC: Action in Exile) but he was able to escape before the Time Lords could enforce a regeneration. (COMIC: The Night Walkers)

Post-regeneration
"Shoes. Must find my shoes."

- The Third Doctor's first words

After being caught in a Time Lord trap that resulted in an enforced regeneration in his TARDIS, (COMIC: The Night Walkers) the freshly regenerated Doctor collapsed outside his TARDIS on 20th century Earth, near a UNIT patrol. He was taken to a hospital unconscious, where he suffered numerous moments of consciousness before falling unconscious again. Escaping from the hospital by appropriating an ornate outfit and commandeering a sporty antique roadster, the Doctor made his way to UNIT HQ to see Brigadier Alistair Gordon Lethbridge-Stewart.

However, he was uneasy about the Brigadier since their last meeting and eager to reclaim his TARDIS key to escape the planet. However, the Doctor found not only that his knowledge on how to operate the TARDIS had been blocked, but also that the dematerialisation codes had been changed. Learning that, when he arrived on Earth, a swarm of power units for a non-physical alien intelligence known as the Nestene Consciousness had been uncovered, and that the Nestene Consciousness had an affinity for plastic and planned to replace key government and public figures with animated humanoid facsimiles called Autons, the Doctor agreed to work for UNIT for the time being.

With the help of Dr. Liz Shaw, the Doctor created a device to stop the Autons. The Brigadier feared that the Nestenes would return, and asked for the Doctor's continued assistance. The Doctor agreed to join UNIT as their scientific advisor, using the identity of Dr. John Smith, in exchange for facilities to repair the TARDIS. He also requested similar clothes to the ornate outfit he had appropriated during his escape from the hospital, and a car like the sporty antique roadster he had also commandeered during the escape, since he would need to return both to their proper owners. (TV: Spearhead from Space)

Adjusting to Exile
The Brigadier gave the Doctor ownership of a bedroom in UNIT HQ, (PROSE: Qualia) and the Doctor was also put on the UNIT payroll, but rarely cashed his pay cheques, (PROSE: No Future) with the Twelfth Doctor seemingly being oblivious to his payments. (TV: Death in Heaven) As payment for his work for UNIT, the Doctor began to ask for pieces of technology to be used in repairing his TARDIS, (COMIC: The Multi-Mobile; PROSE: Three Wise Men) as he had discovered that the human race had managed to discover and catalogue a considerable amount of alien technology in the last century, although they lacked the understanding of what most of it actually was capable of. (PROSE: Three Wise Men) Despite these accommodations, the Doctor harboured great resentment at the Time Lords for triggering his regeneration, bitterly suspecting that he'd been forced to change so that he would grow to like his cage. (COMIC: The Heralds of Destruction) He began to taking evening strolls through a London park regularly. (COMIC: Assassin from Space)

UNIT career begins
The Brigadier took the Doctor to an investigation on an oddly situated zoo, where they were informed and shown that the more dangerous of the animals were acting docile and domesticated while the animals known to be personable and friendly were acting violent and rambunctious. Discovering that these symptoms had started during a school field trip to the park, the Doctor deduced that one of the students at Arkwood Private School had to be behind this. Travelling to the school, the Doctor and the Brigadier discovered that at least one student had already suffered the same symptoms. Soon, the entire school had been contaminated and the students prepared to attack the local town. While the Brigadier and the school's Headmasters tried and failed to stop the students at the school entrance, the Doctor formulated a chemical antidote and cured the students, as the student behind the incident was sent to a detention centre. (COMIC: The Arkwood Experiments)

The Doctor encountered three foreign agents who had stolen an advanced Multi-Mobile to attack the British Nuclear Defence Control Centre. The Doctor stopped them by putting sugar cubes in the petrol tank. (COMIC: The Multi-Mobile) The next threat he faced were large insects, including caterpillars and ants. He discovered insecticide had been badly mixed and created an antidote to return the insects to their normal size. (COMIC: Insect)

After he successfully resisted attempts to extract his memories by an alien Extractor, (PROSE: The Mind Extractors) the Doctor investigated mysterious power losses and strange lights in the sky near Grestonspey and discovered that they were being caused by the alien Zeld and their Proto servants. (PROSE: The Ghouls of Grestonspey) He later tracked down stolen samples of dust from the planet Sequiz, which transformed into an alien creature when scientist Dr Rossi exposed it ultraviolet light. The creature returned to its home after the Doctor battled it. (PROSE: Caught in the Web)

The Doctor discovered that a sentient virus had arrived on Earth and had begun taking control of UNIT personnel. He freed them with a x-ray machine, and then destroyed the virus with a disinfectant. (PROSE: Invaders Invisible) He later investigated Sayle College and discovered that the inhabitants of a dark planet were planning to bring the teachers and students to their world and perpetuate their civilisation. A fire burned down the college, but the Doctor suspected that the aliens might try again. (PROSE: The Dark Planet)

The Doctor investigated mysterious earth tremors in a system of underground caverns and discovered that cave insects had mutated into giants. He was nearly captured and fed to their young before escaping, badly frightened and grateful that UNIT would destroy the creatures with cyanide. (PROSE: Caverns of Horror) He later picked up a distress call on his sub-space radio from Antar, a world in a sub-atomic universe. His attempt to rescue the Antarians failed, as they had been nearly wiped out by the Valerons. (PROSE: A Universe Called Fred) The Doctor investigated reports of rusting metal, finding it was from a meteorite that had crashed nearby. (COMIC: The Metal Eaters)

The Doctor and Liz went to Stegmoor when Daniel Gregson saw a Voord spaceship crash, but, because of its camouflage, the Doctor was unable to find the ship. (AUDIO: Beachhead)

The Doctor was captured by aliens who wanted to kill him so he would not impede their invasion of Earth, but he defeated them with a laser in his cane, (COMIC: Assassin from Space) and then infiltrated the base of foreign agents who had stolen UNIT technology, using his obedience spray to retrieve it. (COMIC: Undercover)

Summoned by the Brigadier to an underground research centre on Wenley Moor, the Doctor and Liz met Silurians, a species who had gone into hibernation millions of years earlier, revived by power from the research centre. The Doctor strove for peace between the reptiles and humans and gained the trust of the Silurian leader. However, a rebellious and intolerant young Silurian killed his leader and released a deadly virus that threatened to wipe out humanity.

The Doctor and Liz found an antidote, but the Silurians retaliated by taking over the research centre. They planned to destroy the Van Allen Belt, a natural barrier shielding the Earth from solar radiation harmful to humans, but beneficial to reptiles. The Silurians had to return to their caves when the Doctor overloaded the reactor, threatening a nuclear explosion. As the Silurians retreated to their base to go back into hibernation until the radiation in the area subsided, the Doctor stopped the reactor from exploding. However, the Brigadier, on the orders of his superiors, had the Silurian base be sealed off with explosives, killing the Silurians. (TV: Doctor Who and the Silurians)

After the Wenley Moor massacre
Angry at the outcome of Wenley Moor, the Doctor drove to Whitby by himself. There he met Ronald Henderson and the two bonded over both being captains stripped of their vessel. (AUDIO: Landbound) Leaving Bessie behind in Whitby, the Doctor travelled on, eventually making his way to Peru by impersonating an air stewardess. The Brigadier eventually caught up with him and the two men talked, with the Doctor agreeing to come back to help UNIT. (AUDIO: AWOL)

Still distrustful of the Brigadier, the Doctor went to meet an alien on his own, but many UNIT soldiers followed him. The alien had attempted to communicate with local citizens telepathically, killing them. As it attempted to talk with the soldiers telepathically, the Doctor was forced to kill the alien to save the soldiers. (PROSE: The Straw that Broke the Camel's Back)

The Doctor was sent to investigate the disappearance of two RAF jets gone missing near Portsoy, with RAF Lieutenant Mike Yates being assisted to assist him. Together, they found the missing pilot, Frank Parry, heading for the Easter Aquhorthies stone circle near Inverurie, but died from an electrical discharge when he pressed his palms against the recumbent stone. After Yates had gone missing, the Doctor found him being interrogated by a group of Armidians in a derelict Portsoy house. The Doctor tried negotiating with the Armidians, telling them that their planet, Tharos, no longer existed, but Yates broke free and Benton opened fire on them as they escaped.

Back at UNIT's mobile headquarters in RAF Lossiemouth, the Doctor received a recorded message from a future incarnation of himself, telling him not to let the Brigadier destroy the Tharon stone from which the Armidians drew power from the area's igneous rocks, and to preserve it for Professor Reynard at the Royal Society. Back at the Easter Aquhorthies, the Doctor ordered Yates and his men to earth the Tharon stone with the nearby wire fencing, rendering it powerless. The Doctor survived a murder attempt by Garlin, but was unable to save him. According to this account, Yates was then promoted to captain when being recruited to UNIT by the Brigadier. (AUDIO: Vengeance of the Stones)

During one of his experiments, the Doctor was alerted to the presence of an alien spaceship falling to Earth, and went up to meet it on its arrival in the north of England. Retrieving a capsule from the landing site, the Doctor discovered the remains of a Mim, and ran to the TARDIS after he writhed in pain from touching the Mim. Liz later came to inform him that he was impersonated by one of the Mim so they could disable the Earth's defences and pave the way for their invasion. The Doctor asked for the Time Lords' help to deal with the Mim, as the destruction of the humans would damage the Web of Time, but the Time Lord messenger told him that they couldn't interfere with what was happening on the surface of the planet, but informed him that they would deal with the Mim invasion flotilla. The Doctor used this to his advantage and managed to lure the Mim scout from their battle with UNIT back to his ship, where he planned to detonate it and kill the Mim. Unfortunately, Sergeant Robin Marshall was caught in the explosion, which eventually led to the promotion of Corporal John Benton to Sergeant. (AUDIO: Shadow of the Past)

When the Brigadier went to Kriegskind to see his old friend Heinrich Konrad, he asked for the Doctor's help when a set of "ghosts" were attacking the castle. He helped to discover that the Ghosts were a side effect of the drugs they were experimenting with. (AUDIO: Old Soldiers)

The Doctor saved radiation-dependent alien ambassadors from General Carrington, a xenophobic retired astronaut, and arranged the exchange of the ambassadors for three captured astronauts. (TV: The Ambassadors of Death)

While walking down a dark alley, the Doctor was almost attacked by time flies. (COMIC: A Stitch in Time)

At Christmas, the Doctor and the Brigadier argued over the Doctor's electricity bills, until Liz reminded the Brigadier that the Doctor was alone with no family on Earth. On his own, the Doctor checked a ship orbiting Earth, but, after learning it was harmless, returned to the party to apologise to the Brigadier. (PROSE: UNIT Christmas Parties: First Christmas)

The Brigadier, deciding that the Doctor needed some exposure to humanity, ordered the Doctor to look after his godson, Albert, for a day. The Doctor took him to a London zoo, where the young boy stole a part of the TARDIS dematerialisation circuit from his pocket and used it to transport himself into the animal pens. The Doctor found him in the tiger's cage, his hand caught in the tiger's mouth. The Doctor entered the cage, and then instructed Albert how to use the circuit to free himself. He later donated his UNIT expenses to pay for a larger enclosure for the tiger. (AUDIO: Walls of Confinement) The Doctor and the Brigadier were then recruited to look for the remains of a rocket in Haiti, during which the Doctor found the watch of Paul Richmann. (PROSE: Prelude White Darkness)

The Doctor, Liz and UNIT next began working as security at an experimental project to drill through the Earth's crust. The drill head started to leak an oily, green liquid that transformed those who touched it into vicious, primeval creatures who craved heat. The Doctor was transported by the partially repaired TARDIS console into a parallel universe in which the drilling project was further along. He worked with ruthless, alternative versions of his UNIT friends to save both universes. When the drilling site in the alternate universe was destroyed, it gave the Doctor information on the course the project would take. This let him save his own universe at the cost of the director of the operations becoming one of the creatures. (TV: Inferno) The Brigadier later told the Doctor that Corporal Helen Martin, who had been on patrol behind the Doctor's hut at the Inferno Project, had gone missing. The Doctor realised that she had been transported along with him into the parallel universe, and he was thus powerless to help her. (PROSE: Still Lives)

Later, the Doctor persuaded Carpanthans to make peace with humans, (COMIC: The Fishmen of Carpantha) and was sent to the Scottish Highlands to determine if a rock which scientists had found was from Venus. Finding it a fake, Dr Logan sent the Doctor into space, but the Doctor piloted the ship and threatened to drop it on Logan's ancestral home, a ploy that proved successful. (COMIC: Doctor Who and the Rocks from Venus)

After hearing about the Doctor's exile, decided to visit him and get revenge for his entombment in the 11th century. He convinced the Doctor that he would take him to the 51st century where he could acquire a vortex manipulator. Instead, the Monk trapped him in a period during the formation of the Earth and he was only brought back to the 1970s when Liz convinced the Monk to return. (AUDIO: The Blame Game)

After an invasion of what seemed to be Goblins and Selkies commanded by the Witch-Queen Karolina, the Doctor and Liz, among many other people, were evacuated to Ireland. After an encounter with the Witch-Queen, it was revealed by the Brigadier that she was actually Caroline Brown, a woman with mental illness. She had escaped from the hospital and had found a staff that could make people see whatever she wanted them to see. Caroline was taken back to the hospital, swearing revenge. (PROSE: The Science of Magic)

While conducting an experiment on an alien fragment recovered by UNIT's Chinese branch, the Doctor was able to convert the Time-Space Visualiser into a Time bridge, allowing him to travel to the island of Salutua in 1934 in an attempt to bypass his exile. However, when this trip resulted in the creation of an alternate timeline where actress Nancy Norton essentially conquered the world using the mesmeric influence of Brokk and phials of drugs created by the Semquess, the Doctor, Liz and UNIT were forced to travel back again to defeat Nancy and undo her efforts. (PROSE: The Eye of the Giant)

During one of his attempts to repair the TARDIS, it sent the Doctor and Liz to 1539 where they met Henry VIII. With his sonic screwdriver, the Doctor cured Henry of his cataracts, whilst Liz cured him of hiccups. After this, Henry invited the pair to Hampton Court, but they declined. (PROSE: Hiccup in Time)

Liz resigns
When Jean Baisemore, a friend of Liz's, disappeared, the Doctor investigated twelve other disappearances and was led underground by a Cybermat, where he re-encountered the Cybermen. Making peace with his old foes, the Doctor's relationship with the Brigadier was strained once more when Lethbridge-Stewart sent UNIT soldiers to destroy the Cybermen. (AUDIO: The Blue Tooth)

After the Doctor found out that Liz was involved in dismantling an alien computer, he came to help her do it after she was transported inside it. After this, Liz announced her intentions to leave UNIT. (AUDIO: Binary)

When the Doctor discovered evidence of a new Silurian colony, he attempted to make contact with them himself, but this triggered a near-conflict with the colony, populated by Silurian-Sea Devil hybrids seeking a way to breed further, and a renegade faction of C19 seeking to use alien technology to conquer the world. The Doctor and UNIT were able to thwart these efforts and expose the true conspiracy, but the Silurian colony decided to remain in secret for the moment. Faced with the brutality and near-death of these events, Liz decided to return to Cambridge, hoping to make a more conventional difference with the knowledge she had gained from her time with the Doctor. According to this account, Yates had already been promoted to captain after working for UNIT as a sergeant. (PROSE: The Scales of Injustice)

After Liz left UNIT, the Time Lords sent the Doctor to Earth's future to retrieve a capsule for Liz Shaw. He found that Liz had reshaped the world along purely rational lines. The Doctor helped the alternate UNIT stop Liz and returned to his normal time, where he gave Liz the capsule. Within it, she found a recording of her dreams of the future and, shocked, she agreed to put her intelligence to better use. (PROSE: Prisoners of the Sun)

The Doctor was asked to investigate some crops circles and discovered they came from the Ikiria. He went missing soon after the Ikiria arrived. When Captain Yates found him, he said he deliberately hid in order to find a way to stop Ikiria by finding the right crystals. (AUDIO: The Rings of Ikiria)

While on vacation in the Caribbean with the Brigadier, the Doctor had Fredric Simba arrested for attacking them with a giant squid. (COMIC: Castaway) The Doctor later got around to reading his copy of Levitation Universal Edition and from it learned how to levitate. He used this ability to save a criminal from falling off a building. (COMIC: Levitation)

The Doctor obtained a power source great enough to make a quick trip in the TARDIS. He found himself at a masked ball during the Napoleonic Wars with Emma Hamilton. Aliens landed to retrieve Emma's ring, which was actually the species' power source, sent back in time. Lord Hamilton had his wife give them the ring, and the Doctor returned to his own time. (PROSE: Danse Macabre)

The Doctor was asked by Professor Carl Readon to check the emotions of his new robot. The Doctor found them to be functioning, but after the Professor yelled at one of his assistants for bringing her dog to work, the robot went berserk, attacking a nearby town. The Doctor realised that the robot missed the dog and had the two reunited. (COMIC: Doctor Who and the Robot)

The Doctor investigated a fire at an inn, discovering it had been done by Fire people, an ancient race that lived beneath the Earth. While most of them were peaceful, a faction associated themselves with Professor Victor. Victor and his Fire people chased the Doctor across the world, until they arrived at the Arctic, where the Fire people burned out and Victor collapsed. (COMIC: Trial of Fire)

The Doctor was asked by millionaire John Henderson to drive his time-travelling bulldozer into the future. In the future, the Doctor found the society of 2971 to be primitive and warlike, ruled by Henderson's descendant, King Trent. The Doctor helped them see the error of their ways and returned home to show Henderson the true value of friendship. (COMIC: The Kingdom Builders)

While battling the Waro, the Doctor worked with Liz again, having missed her. (PROSE: The Devil Goblins from Neptune) While he and the Brigadier were at the Cabinet Security meeting, Liz was visited by, which made her want to return to Cambridge permanently. (PROSE: Reconnaissance)

Battles with the Master
The Doctor's new assistant at UNIT after Liz left was Jo Grant. After being warned about coming to Earth, the Doctor convinced the Master to stop his alliance with the Nestenes, after providing them with a bridge-head allowing the aliens to return to Earth and creating weapons and tactics, as the Nestenes would not distinguish between the Master and anyone else in their takeover, and the two worked together to fling the Nestenes back into space by "chang[ing] the polarity" whilst the transfer shift of the radio telescope that summoned the Nestene invasion force was still open. The Doctor had also stranded the Master on Earth after stealing the dematerialisation circuit of the Master's TARDIS. (TV: Terror of the Autons)

The Doctor was contacted by Liz Shaw and went to Cambridge to investigate time distortions due to a time experiment. He and Liz travelled through one of the Time Distortions to 2014 and encountered the Sentinels of the New Dawn and stopped them from releasing Ebola on the world. (AUDIO: The Sentinels of the New Dawn)

Discovering some time disturbances, he and Jo tracked the source down to museum where there was a strange artefact. The Doctor discovered that the item came from an alternate universe which was running backwards, and that Doreen Killebrew knew the artefact's owner who was trying to get it back. (AUDIO: The Doll of Death)

With Jo alongside him, the Doctor went to meet two astronauts who had returned from Mars. The Doctor learned their minds had been taken over by Minoans, a ruthless alien life form. When the aliens tried to take over the Doctor's mind, he returned the astronauts to normal, and the Minoans retreated. (PROSE: Dark Intruders)

The Doctor discovered his old friend, Giles Winston, had gone missing. He and Jo tracked Giles to an abandoned wartime factory, but both found that the Master had lured them into a trap, having found a way for both him and the Doctor to escape their exiles. He had brought the Doctor to help Winston Churchill perfect a portal into another dimension. As Jo jumped out of the Master's reach, he shot the portal, closing it for good. (PROSE: Doorway into Nowhere)

The Doctor, Jo, and Mike Yates were driving to a remote island where people had been reported missing, having been trapped in a mist. On the way there, they picked up an elderly hitchhiker named MacFee, who picked up a pot by the island. On arrival, MacFee turned out to be the mist itself, and the Doctor woke in a ship next to a large crab, stopping the mist by blowing up its ship. (PROSE: The Claw)

When strange lights appeared in the sky and the diamonds of the world began to disappear, the Doctor concluded that aliens were hidden in the sky. The Doctor made glasses to see them and a weapon to attack them. (PROSE: The Phaser Aliens)

The Doctor visited Stangmoor Prison with Jo for a demonstration of the Keller Machine, a device to extract negative emotions from hardened criminals. The Doctor discovered that the Master was behind the machine, but also that he had lost control of it. The machine was destroyed along with the Thunderbolt missile the Master tried to launch at the World Peace Conference, but the Master recovered his dematerialisation circuit and escaped again in his TARDIS. (TV: The Mind of Evil)

The Doctor, Jo and the Brigadier encountered the lord Hades, whom they stopped with the help of and Zeus. (PROSE: Deadly Reunion)

The Doctor investigated a hospital, where he found a woman named Marion Connors, envious of those fitter than she, had dreamed of making the people she hated sick. Marion asked him to kill her, but instead, he told the other patients how to avoid her attacks. Unable to torment anyone any more, Marion lost the will to live and died. (PROSE: Angel) The Doctor later took a trip to the theatre to see a Peter Cushing film. (PROSE: A Visit to the Cinema)

At Christmas, the UNIT party was interrupted by the Master, disguised as a scientist from Geneva. He claimed that he only wanted company for Christmas, and the two Time Lords shared a drink before the Master left. (PROSE: UNIT Christmas Parties: Christmas Truce)

When mysterious holes containing passages through different time periods started appearing along a Dorset beach, the Doctor went out to investigate alone. As he was studying the phenomenon, he was attacked by a Viking warrior, but was rescued by Kate Stewart and an older Jo, both having arrived through one of the holes from the 2010s. The Doctor accepted their help and with their assistance devised a machine that could repair the anomalies in time. When an entity tricked Kate into reprogramming the system and enlarging the holes, the Doctor was able to stop the ensuing chaos, but could not use the device to correct the anomalies anymore. He then decided to enter the Time Vortex himself to put things right, at the possible cost of his own life, but Jo knocked him out and went in his place. Her act was successful, and she managed to close the holes. The Doctor then spent the following years trying to find a way to save Jo. (AUDIO: The Sacrifice of Jo Grant)

When a seemingly benevolent alien species known as the Axons arrived, promising new means of energy, the Doctor immediately saw through their charade; they had no intention of helping Earth, instead they planned to drain it dry of all energy. The Doctor once again encountered the Master, who had been captured by Axos after leading them to Earth; the Doctor put on the pretence of abandoning his friends at UNIT while working with the Master to repair his TARDIS. While the Master escaped once again, the Doctor succeeded in trapping Axos in a time loop before departing himself. However, much to his displeasure, the Time Lords had anticipated him leaving Earth and so reprogrammed the TARDIS to always return him to the 20th century. (TV: The Claws of Axos)

The Time Lords allowed the Doctor to pilot the TARDIS to Estringokl on a promise he once made to the townspeople to decorate their Christmas tree, as the robot he had once found to do the job had frozen with all the people of the town. Although the Doctor was hoping to take Jo to the festival of Planetfall, they soon realised the purpose of their visit. After visiting every year for eleven years to decorate the tree, the sun flared and the people awoke. The Doctor and Jo then quietly left the colony. (PROSE: The Thousand Years of Christmas)

The Doctor was reunited with Liz Shaw again when she invited him to a lecture on psi powers. Professor Brockbank, a teacher at Cambridge who was to attend the lecture, had died, choking on food. The engines on the plane they were on went out, but they stayed in the air thanks to a woman with psychic abilities, who died once they landed. Liz recognised her as a pupil of Brockbank's rival, Hardin. After Hardin refused to talk to them, the Doctor theorised that Hardin had caused Brockbank's death and that he had been performing improper surgery on his students. Calling the Brigadier and organising a mass protest against Hardin, Hardin admitted surgery on his students, as well as on himself. He tried to suffocate the Doctor with his powers, but instead, the Brigadier shot and killed him. (COMIC: Change of Mind)

The Time Lords sent the Doctor to space station XZ49, where his old companion, Zoe Heriot, was stationed. The Time Lords' removal of her memories was failing, and the Doctor believed he had been sent to retrieve the dematerialisation codes from Zoe. After he found that she would lose her memories permanently if he did so too quickly, Zoe's superior, Sandra Urtiman, brought her to the TARDIS. Her memories returned too quickly and she collapsed, with the Doctor realising that this was the Time Lords' intention. (PROSE: The Tip of the Mind)

When the Time Lords discovered the Master had stolen their secret file on the Doomsday Weapon, they sent the Doctor and Jo to retrieve it on the planet Uxarieus, where they met resistance with the Interplanetary Mining Corporation, who tried to claim rights to the planet with highly unethical means and forcing the colonists to vacate, despite them not being able to do so with their old and damaged ship.

Taking advantage of the standstill between IMC and the colonists, the Master posed as an Adjudicator who could overturn the decision in favour of IMC. The Doctor had little choice but to play up to the Master's whims after a native alien tribe had stolen the TARDIS. He learned the Master's disguise was a ploy to reach a forgotten alien civilisation on Uxarieus, planning to seize the power of one of their weapons. However, the Doctor met the primitives' intelligent leader in the civilisation's city. Because it was intelligent, the Doctor reasoned with it, convincing the guardian to destroy the weapon and all traces of its civilisation before the Master could misuse the technology it held. The Master escaped to freedom. The Doctor reclaimed his TARDIS and left Uxarieus in the hands of a real Adjudicator. (TV: Colony in Space)

The Doctor tried to stop the Master, posing as a rural vicar, from summoning Azal, the last of the Dæmons, at Devil's End. Azal decided to give his power to the Master, and fired energy at the Doctor to kill him, until Jo stepped in front of the Doctor, asking Azal to kill her instead. This act of self-sacrifice did not make sense to Azal and the confusion destroyed him. The Master tried to escape in Bessie, but the Doctor's remote control brought the car back and the Master was finally captured by UNIT. (TV: The Dæmons)

The Master's trial
The Master was blamed by the media for many of the alien activities at that time, (PROSE: Who Killed Kennedy) and, after being transferred to a new holding cell, regressed the Earth to a primitive place and escaped in his TARDIS. The Doctor stopped him with his own TARDIS and quickly had him locked back up. (PROSE: Freedom) Shortly afterwards, Major Carver, the father of a soldier vaporised by Azal's servant, Bok, held the Doctor and the Brigadier hostage until they told him his son had died fighting against the Master. (AUDIO: Degrees of Truth)

The British government sought to execute the Master for his crimes, but the Doctor successfully advocated for him to instead receive a life sentence, arguing that he was capable of being rehabilitated. (PROSE: Doctor Who and the Sea-Devils)

After the Master's arrest
The Doctor fought the Nestene Consciousness as it attacked humanity with artificial flowers. (POEM: The Flower Sour)

Attempting to start his non-functioning TARDIS in Wales, the Doctor accidentally arrived in Australia. He was taken to the Gemini Plan, where scientist Rudolph Steiner planned to shoot a missile to Venus. The Doctor changed its destination to the Sun, where it was destroyed. (COMIC: Gemini Plan)

Back in London, the Doctor discovered a time link to Nazi Germany, 1942. He went there and stopped the Nazis from returning to 1978 by setting their transporter to London, 1942, where they were arrested. The Doctor set the controls back to 1973 and returned home. (COMIC: Timebenders)

The Doctor, with the assistance of Captain Fenton of the Royal Navy, killed a creature that attacked a frigate in Portsmouth harbour. (PROSE: The Thing from Outer Space)

The Doctor later helped Mike investigate strange weather patterns that were happening in the summer, and noticed that there was an odd energy spike at the same time, which he discovered was due to an alien spaceship and its inhabitant, Diamond Jack. (AUDIO: The Magician's Oath)

The Doctor visited the Master at Aylesbury Grange, where he was being held. The Master insisted he had changed, only to reveal he had escaped, and that the Doctor was speaking to a hologram. The Master nearly escaped, but was stopped by soldiers. (COMIC: The Man in the Ion Mask)

When a Mileu spaceship was sighted near East Anglia, the Doctor was reluctant to take action as he believed they were likely peaceful and was more intrigued by a device which had appeared in his TARDIS. He was visited at UNIT HQ by Prime Minister Jeremy Thorpe who was determined to persuade him to take action. The Doctor initially brushed him off however when a listlessness field began affecting the UK he hurried in Bessie to confront the Mileu with Jeremy alongside him. After they arrived at the coast near the spaceship, the Mileu teleported the pair aboard and revealed they were not responsible for the field, but were hunting the alien fugitive who was. Having deduced its purpose, the Doctor threatened to use the device to strengthen the field to affect the Mileu, prompting them to retreat. Afterwards Jeremy confessed he’d spoken to the alien fugitive when he’d called the Damascus project earlier in the day. Furious the project was still operating despite his objections, the Doctor abandoned the Prime Minister on the beach. From this incident Jeremy decided that the Doctor's morality was dangerous and recorded a message stating that the Doctor must be stopped. (AUDIO: Damascus)

Missions in time
Freedom fighters from an alternate 22nd century tried to thwart a Dalek invasion by coming to the 20th century to assassinate a delegate, Reginald Styles, at the second World Peace Conference in Auderly House. (TV: Day of the Daleks) Whilst investigating the ghosts Styles had seen, the Doctor met Ace, who possessed a sword, and exchanged in a sword fight in which he emerged the victor, only for Ace to disappear when she grabbed his blade. (COMIC: Time & Time Again) After following the guerrillas back to the 22nd century, the Doctor realised that Styles' actions had instead been performed by Shura, one of the fighters, in a misguided attempt to fulfil his mission, creating a temporal paradox. After travelling to the 20th century, the Doctor returned to ensure the evacuations of the delegates, having the Brigadier order his men to fall back and allow the Daleks to pass. The Daleks and Ogrons arrived in pursuit of the Doctor, but both were destroyed when Shura detonated his bomb. This intervention broke the paradox so the Dalek invasion never took place. (TV: Day of the Daleks)

Directly after fighting the Daleks, the Doctor met journalist James Stevens. Stevens had been researching the Doctor ever since his exile began, along with UNIT, and was being attacked by an Ogron, from whom the Doctor saved him. The Doctor had seen James's newscast, where he claimed that "Victor Magister" headed the government organisation C19. James was sent to a UNIT bunker, where he was given the Doctor's number. Over the phone, James described a golden ring he had found. The Doctor identified it as a time ring and gave James instructions on how to use it. Following these instructions, James travelled back to 1963, where he stopped the Master from destroying Earth. Watching the events unfold, the Doctor decided to visit his old friend in prison. (PROSE: Who Killed Kennedy)

On Halloween, the Doctor and Jo investigated a signal being broadcasted into the Time Vortex from New Alverton by a Dalek left over from the Auderly House attack. The Doctor took the Dalek back to UNIT under the agreement he would use equipment from the TARDIS to send a distress call to the Daleks, but the Doctor really intended to harvest the time-codes to repair his ship, knowing the Dalek's jury-rigged repairs would make it a target for extermination. When the Dalek realised the deceit, it tried to kill the Doctor by self-destructing, but the Doctor managed to deactivate it before it could explode. (PROSE: The Monster in the Woods)

During an invasion by silver crabs along the British coastline, the Brigadier and the rest of UNIT began to find it difficult to remember the Master when they were called in to investigate a mysterious incident on a North Sea drilling platform. The Doctor deduced the silver crabs were Sild, and were causing everyone to forget the Master by what he called "time fade". The Doctor decided he had to spring the Master from his prison at Durlsdon Heath before the Sild got to him, but his time ran out and the Brigadier had to have the RAF blow up the prison. In the aftermath, the Doctor and the Master travelled to the far future to destroy the Consolidator and all the Sild on board. Sometime later, the Doctor returned to UNIT, without the Master. Then, the Master also showed up to gloat, but once again UNIT were able to successfully arrest him and take him away. (PROSE: Harvest of Time)

Thinking he had fixed the TARDIS, the Doctor and Jo took it on a test flight, but due to the Time Lords' intervention, (PROSE: The Face of the Enemy) the Doctor accidentally landed the TARDIS on the ledge of a great cliff, which gave way and caused it to fall to the bottom of the chasm, on Peladon. After a cautious climb to safety in the middle of a turbulent storm, the Doctor and Jo entered the citadel of Prince Peladon, where the Doctor was mistaken for a human dignitary summoned to act as chairman of a committee assessing an application by the planet to join the Galactic Federation, where delegates consisted of the Ice Warrior Izlyr, the Alpha Centauri and Arcturus. There proved to be a conspiracy between a Federation delegate and the High Priest of Peladon, and the Doctor and Jo revealed this conspiracy to the Prince. When the delegates began to point fingers at each other in blame, the Doctor himself accused, all suspicions were rendered futile.

However, the Doctor discovered that Peladonians worshipped a mythical beast named Aggedor, which turned out to be real. After encountering it, he learned a Venusian lullaby could calm it, it feared fire, and it could fall under hypnosis. Aggedor was simply a wild creature confined to the citadel in a temple, but the Doctor faced a punishment of execution for desecrating the inner sanctum of Aggedor's temple. Through a plea, he was allowed to battle for survival in a pit fight against the mute warrior Grun instead. The Doctor won the match and spared Grun, since he was a simple and frightened soul at heart. However, delegate Arcturus revealed himself as a traitor working for Hepesh and attempted to snipe the Doctor from above the pit, however, Ssorg killed Arcturus before he could kill the Doctor.

Hepesh had refused to let Peladon join the Federation because he held fast to the old customs of the planet, which would soon be abandoned if an alliance changed the ways it was governed. He used Aggedor to kill Torbis, let Aggedor run wild through the citadel and cause chaos and framed the Ice Warriors as part of a bid to sabotage the delegation, creating dissent between all parties. The Doctor brought Aggedor to the Prince of Peladon so he would also learn of its presence, but Hepesh tried to command it to kill as its High Priest and appointed ruler. He intimidated Aggedor with a torch, thinking it would obey out of fear, but instead, it provoked Aggedor into fatally mauling him. With the traitors condemned, relations between the Federation and the Peladon Kingdom were improved. After the TARDIS had been heaved up the mountainside, the Doctor and Jo had to disembark immediately from Peladon when the real Earth delegate arrived and they were outed as impostors. (TV: The Curse of Peladon)

The Doctor and Jo were then transported to 1973 by a time twister operated by Casimer, a young girl from the 23rd century, who the Doctor helped send home, (PROSE: The Sommerton Fetch) and encountered what they believed to be ghosts, but they were actually Psion orbs, items made to project emotion, (PROSE: Spoilsport) before returning to UNIT HQ. (PROSE: The Face of the Enemy)

One night, Tuala broke into UNIT headquarters and took Jo hostage. The Brigadier attached a homing device to her getaway vehicle so the Doctor could pursue them in Bessie. The Doctor reached the house that Jo was being kept in, but Tuala used a black box to transport herself and Jo away. After finding a newspaper mentioning Bernard Forbes' death, the Brigadier and the Doctor visited his wife to talk to her about Bernard's death, but found him alive in a deteriorating mental state. The Doctor deduced that Tuala's uncle, Krashen, was changing history for money. Confronting him, the Doctor pointed out that time was destroying the house, Bernard Forbes, and Krashen himself. Krashen used his machine to take himself and the Doctor to the bedroom at the time Jo and Tuala were in it. Tuala and Krashen faded away. The Doctor and Jo then barricaded the landing to delay the entrance of the earlier Jo and Tuala. The Doctor fixed the time machine and the room exploded. After waking in the UNIT sickbay, the Doctor travelled to Forbes' house to find that Bernard had just vanished after time was put right. (PROSE: Honest Living)

Later, the Master switched bodies with the Doctor in an attempt to escape incarceration. In the Master's body, the Doctor lured his guards into his room and attacked them, but was eventually restrained and locked up again. Realising that he would be back in his cell soon, the Master decided against leaving a trap for the Doctor as it would be more confounding for him if he didn't. After being put back in his own body, the Doctor apologised to Jo for "his" rudeness that day. (PROSE: The Switching)

The Doctor, Jo and the Brigadier encountered space-hounds who wore metal suits, who started pursuing them. The Brigadier killed one by shooting it with a bazooka, and Jo killed another by user her hand mirror to reflect a laser beam. Upon regrouping with Yates and Benton, the Doctor used his sonic screwdriver and a loudspeaker as a dog-whistle to knock the rest unconscious. (COMIC: The Forgotten)

The Doctor and Jo visited the Master, now imprisoned on Fortress Island. He claimed to have reformed, but still refused to reveal the location of his TARDIS. As they left, the governor, Colonel Trenchard, told them ships had been disappearing. The Doctor investigated, and discovered that the Master had used Trenchard's sense of duty to manipulate him into stealing electrical equipment from the naval base HMS Seaspite to build a machine to control the Sea Devils, hoping to use the reptiles to conquer the world. The Doctor entered the Sea Devils' base and tried to encourage peaceful negotiation, but the Royal Navy, under orders from Private Secretary Walker, attacked the base with depth charges, causing more hostilities between humans and Sea Devils. The Doctor escaped with the captured navy crewmembers and their submarine, and returned to HMS Seaspite, which was promptly captured by the Master and the Sea Devils.

The Master forced the Doctor to create a sonar device that would reactivate more Sea Devil bases, but the Doctor plugged it in improperly, creating a noise that temporarily incapacitated the Sea Devils, and allowing time for Jo and Captain Hart to gain reinforcements to recapture HMS Seaspite. The Doctor chased the Master and his device into the Sea Devil base, and overloaded the device by reversing the polarity. This destroyed the base, preventing more bases from being activated and stopping the war. With the Sea Devils destroyed, the Doctor was prepared to return the Master to prison, but the Master successfully made his escape. (TV: The Sea Devils) Returning to UNIT HQ, the Doctor met his eighth incarnation, who had lost his memory. The Third Doctor blamed the Eighth Doctor for the advice he gave the Second Doctor which led to his exile, as well as the Master's concurrent escape. At first, he threatened him with the Tissue Compression Eliminator, but tossed the weapon to him instead. Having regained the memories of his third incarnation, the Eighth Doctor left. (PROSE: The Eight Doctors)

The Doctor encountered a noveliser named Huxley, and Iris Wildthyme. (AUDIO: Find and Replace)

The Doctor and Jo travelled to Greece in the 1950s. As they left the TARDIS, an earthquake occurred and it fell into a crevice. They saw it fall again and realised that they were in a time loop. They met a man called Katsoudas, who claimed to be on a mission for the Time Lords. They headed to Katsoudas's dig site, where the benefactor of the experiments was revealed to be the Master, who was trapped in a time loop, along with the Odobenidan crew of a spaceship. The Master was using earthquakes to free himself, despite the damage to Earth's Mediterranean region. After Nikos Spiridakis meddled with the controls for the Master's equipment, the Master fled in his TARDIS. Katsoudas told the Doctor of his plans to continue his experiments with the alien equipment, but the Doctor wouldn't allow it and removed him from his own time to protect the Web of Time. (PROSE: The Seismologist's Story)

The Doctor worked with his successor, who kept his identity secret to maintain the timelines, to defeat the Sea Devils, who had launched an attack on a submarine after being accidentally awakened. After they were successful, the Fourth Doctor left before the Third Doctor could realise his true identity. (COMIC: Under Pressure)

The Time Lords ordered the Doctor to deliver an object to an unknown person in the 30th century, near the end of the Earth Empire, on the colony world of Solos, where the humans were becoming hideous mutants. The Doctor, with the help of Professor Sondergaard, discovered the transformation was a natural part of the Solonian life cycle. A Solonian leader, Ky, eventually went into his metamorphosis and killed the Marshal of Solos, who had been committing genocide against the mutants. The Doctor was instrumental in finding the crystal on Solos that was necessary to spark their final metamorphosis into a higher existence for the coming of the planet's long summer climate. (TV: The Mutants)

The Doctor and Jo travelled to the prehistoric jungle planet Quorus and noticed that the Master was controlling a dinosaur-like animal with a gadget. They saw him collect something and then leave in his TARDIS. They tracked him to Earth, but lost him when they entered the atmosphere. After a similar creature destroyed a warehouse, the Doctor and Jo, with armed forces, travelled there and found rubble and an egg shell. The Doctor realised the Master's plan and after hearing a report of a trail leading to the top-secret weapons research station Darisdale, he and Jo headed there in Bessie.

They arrived at Darisdale, but were refused entry by a Major. As they turned around and drove away, the Master watched them and set the giant animal after them. In a quick effort, the Doctor pressed a button on Bessie's dashboard which ejected oil, stopping the monster in its tracks. The Master teleported the creature to Trafalgar Square, but the Doctor used an ultra-sonic whistle to bring it out of the Master's control. The creature was stopped and killed, the Master escaped and the Doctor stayed behind to witness the staff of Darisdale being placed under arrest. (PROSE: Doctor Who Fights Masterplan "Q")

The Doctor encountered the Master aiding Nurazh, a mind-parasite which fed off its host's life energy. The Doctor battled with the Nurazh, but was pushed off a tall building and died. As his regeneration began, the Nurazh transferred itself into the Doctor's mind. Unable to cope with the two Time Lord minds at once, it perished, healing the Doctor in the process and negating the regeneration. (PROSE: The Touch of the Nurazh)

The Doctor investigated the mystery of five missing people, which led him to a health clinic in a country manor house, where he discovered the shape-changing alien Doctor Dantalion. Dantalion offered the Doctor a drink, but it contained a paralysing agent. He planned to cut the Doctor up for medical research, as he had done to the missing people. Jo came in with a pistol and Dantalion was detained. When the Doctor compared his behaviour to that of a doctor, he realised Dantalion was an actual doctor. As a convoy took Dantallion away, the Doctor bid farewell to Dantalion, but not before he signed over the country manor to him, allowing the Doctor to gain a new base for UNIT, saving their funding from the government. (PROSE: Where the Heart Is)

When the Fourth Doctor used his TARDIS tuner to begin a temporal meta-collision with his other incarnations, the Third Doctor learnt that Earth was under threat from a pandimensional entity that had trapped his fourth incarnation in his TARDIS. The Third Doctor took charge of the situation, organising his other incarnations into teams to combat the threat of the entity and free their fourth incarnation. However, the War Doctor realised that the Sixth Doctor was sending encoded messages on how to defeat the entity and stopped the invasion, and the Sixth Doctor installed a way to expel the entity from the Fourth Doctor's TARDIS, ending the crisis. (WC: Doctors Assemble!)

At a time when the Doctor found himself effectively becoming the Brigadier's telephonist, UNIT received a phone call from the year 2020 from a woman who watched the Doctor's adventures as a television series. The Doctor, Jo and the Brigadier answered the woman, who was looking for advice on dealing with the COVID-19 pandemic. The Doctor commended Jo's positivity, citing that using it helped people. The Doctor gave the woman some final words of advice before leaving the call to deal with a sudden crisis with Jo and the Brigadier. (WC: U.N.I.T. On Call)

The Doctor discovered that the Master had constructed a device known as TOMTIT and commissioned scientists, Ruth Ingram and Stuart Hyde, to further its work at the Newton Institute. The device let the Master pluck various objects from history out of their proper setting and slow down time, though the Master's true goal was to summon the Chronovore Kronos and use its incredible might for conquest. Pursuing him in the Time Vortex, the Doctor accidentally materialised his TARDIS inside the Master's, locking both in a space loop. After much arguing between him and the Doctor, the Master forcibly separated their TARDISes, but launched the Doctor into the Time Vortex. Fortunately, the Doctor used his binary cardiovascular system and the telepathic circuits of his TARDIS to communicate with Jo and instruct her to materialise him back in his TARDIS by using an emergency switch on the console.

The Doctor, Jo and the Master travelled to ancient Atlantis for the other half of the crystal needed to control Kronos, where the Doctor and Jo temporarily enjoyed victory over the Master. However, the Master's charm won over King Dalios's wife, Queen Galleia, making her turn against Dalios's rule. When a guard killed Dalios, however, Galleia turned against the Master in anger, and summoned Kronos with the crystal, resulting in the city's destruction. The Master escaped the destruction, but took Jo hostage in his TARDIS. The Doctor threatened to time ram the Master's TARDIS, but the Master knew he would not risk Jo's safety. Jo, however, tried to carry out the time ram on her own. To their surprise, Kronos itself intervened and told the Doctor and Jo that it was above good and evil. It would grant any wish they desired, but wanted to inflict an everlasting punishment on the Master for trying to control it. The Doctor, knowing that this fate was too cruel, asked that the Master be spared and that he and Jo were sent home to Earth. (TV: The Time Monster)

Whilst at UNIT with Tom Osgood, the Doctor noticed he could only communicate using the vowel "o" and "y". The Doctor and Osgood headed for the Doctor's hut to work on a device that would block the invaders named the Kobolds' signals. However, the Doctor became frustrated with Osgood and stormed into the TARDIS, where he learned he could speak normally. The Kobolds broke in and attacked the Doctor, and, after they seemingly overpowered him, they headed inside the TARDIS, although this was part of the Doctor's plan. When Forty noticed the roundels in the TARDIS, he was distracted long enough for the Doctor to take him back to his planet, Procyon Two. (PROSE: Morphology)

Along with seven other incarnations, the Third Doctor became trapped in the Void when it began to attack and devour the universe, passing through the Tenth Doctor's TARDIS as he was pulled in. He and the others were able to form a dimensional bridge to allow the Eighth Doctor to escape, and were then joined by the War Doctor, followed shortly by the ninth, tenth and twelfth incarnations, who ventured into the Type 1 TARDIS responsible for the disturbance. Forming a plan with the trapped Eleventh Doctor, the Doctors joined their TARDISes to pacify the Type 1 into a peaceful state and return the universe to normal. (COMIC: The Lost Dimension)

The Doctor and Jo were brought to a new training base, Base 43, where dummies of old adversaries were kept. There they met Colonel Ashe, who revealed himself a Russian spy sent to recruit the Doctor.

The Doctor was able to free Roddy from Tommy by forcibly removing the jacket, and had it placed in the Vault. (AUDIO: Tales from the Vault)

At Christmas, the Doctor tried to speak with a drunken man on a train, before he disappeared with a flash. (PROSE: Jigsaw)

The Doctor also met Iris Wildthyme, who helped him encounter robot sheep, aliens who looked like book characters and an alien named Verdigris. (PROSE: Verdigris)

Facing Omega
A superluminal signal was sent to Earth, carrying with it an unusual energy blob that seemed intent on capturing the Doctor. On Gallifrey, the Time Lords broke the first law of time to bring the Second Doctor to help him. When the two proved too different to work together, the Time Lords summoned the First Doctor to lead them, but he was trapped in a time eddy and unable to fully materialise, only communicating with them via the TARDIS scanner.

The Doctors found Omega behind the mysterious disappearances. They prevented him from reinserting himself into the world of matter from his anti-matter domain by blowing it up with a mix of regular matter and anti-matter. As a reward for his services, the Doctor's exile was lifted. (TV: The Three Doctors)

Working on the TARDIS
Celebrating the end of his exile, the Doctor encountered Verdigris again with Iris and Tom, (PROSE: Verdigris) and rescued Liz from 1539.

One day, the Doctor was working on his TARDIS when The Scorchies Show caught his eye. When the Doctor never returned from the studio and was believed dead, Jo confronted the Scorchies. However, the Doctor survived and was spotted in amongst the UNIT soldiers. Professor Baffle activated a device that reversed the polarity causing the Scorchies to disintegrate and Baffle revealed that he allowed the Doctor to infiltrate his personality long ago. The reversed signal destroyed the physical form of the Scorchies and the Doctor conceded that they continue to exist as an intelligence floating through space. (AUDIO: The Scorchies)

Newfound freedoms
Joined by Liz Shaw for the TARDIS' maiden voyage, the Doctor and Jo travelled to Russia, 1916, where they encountered Grigori Rasputin. Liz was brought to the authorities after it was learned she disliked Rasputin because of her knowledge of history. The authorities, who also disliked him, invited Rasputin to a house, where they planned to kill him by poison. Jo saw the men poisoning his food and replaced it with wholesome food. Felix Mather, noticing that he had not died from the poisoning, shot Rasputin in the back, and then went to celebrate.

When he returned to the physical world, he was met by who revealed that the Second Doctor was in fact Ramón Salamander. Tracking down Salamander just as he travelled back to 1868, the Doctor managed to use his friendship with the micro machines to have them stand down. Upon returning to UNIT HQ, the Doctor began making preparations to leave Earth and take the micro machines to a planet where they could develop on their own. (COMIC: The Heralds of Destruction)

The Doctor and Jo travelled to Oxford in the 21st century, where they encountered a man who had nearly died of dehydration in the library.

However, the Doctor hypnotised his guard and then switched the circuits on the Master's matter transporter to explode upon activation before escaping. (COMIC: The Time Thief)

Aliens landed on Earth and began draining energy from it. The Doctor confronted them, and they turned out to be peaceful, only wanting to stop the spread of Molag seeds. (COMIC: Menace of the Molags)

Continued voyages
The Doctor and Jo wound up on the SS Bernice, a cargo ship crossing the Indian Ocean. A monster appeared in the sea, events repeated themselves, and a giant hand stole the TARDIS. Investigation revealed that they were inside a miniscope, an alien peepshow sporting numerous miniaturised environments, which showman Vorg and his assistant, Shirna, had brought to amuse the populace of the planet Inter Minor. After leaving the miniscope, the Doctor returned the creatures to their homes and destroyed the machine, allowing him to return to normal size. (TV: Carnival of Monsters) While working on the miniscope, he encountered River Song. (AUDIO: Peepshow)

The Doctor then encountered extreme temporal anomalies, which he was eventually able to stop, (PROSE: The Suns of Caresh) and was saved from an Entity by his first incarnation. (AUDIO: Seven to One)

The Doctor and Jo were sent to a planet where a computer put them through many deadly games and quizzes, (PROSE: The House That Jack Built) and encountered a creature which wished to live forever, but needed the Doctor's body to do so. (PROSE: Revenge of the Phantoms)

The Doctor visited Freedonia, a planet that he had been to before when helping in a revolution. He discovered the people were now slaves to Kamoa, one of the leaders of the revolution who was now nothing more than a brain. Jo convinced one of Kamoa's servants, Bolgar, to unplug the brain, freeing the people. (COMIC: After the Revolution)

The Doctor and Jo visited a rock concert on the planet Rishik, where an earthquake occurred. The Doctor rushed back to the TARDIS, where he discovered that the quake had affected the entire planet except for the house of Genus Fry, the planet's most famous rock star. The Doctor discovered that Fry was a psychic, who could see into the future, but for the last ten years could only see darkness. He was visited by two Rock-based Tuns, Oke and Erm, who revealed that the planet had nuclear power stations on each side, which posed a threat to the planet, and Fry agreed to help create the earthquakes, choosing the lesser of two evils. The Doctor was able to stop the earthquakes with Fry's help, but Fry died in the process. His mind, however, was placed into a spare Tun body, and the Doctor stated that now he was a true "rock star". (PROSE: Rock Star)

The Doctor then took a trip to an island in the Bermuda Triangle so that Jo could sunbathe, but discovered a tall man lived on the island. The man thought them to be gifts from God and Santa Claus and did not ask to be rescued, so they left without him. (PROSE: Lost and Founded)

Jo and the Doctor then went to a desert planet, where two sisters, Sophia and Alice, were competing to become queen. The final task was to guess the three objects in a sealed temple. Sophia, who had cheated by looking, guessed a crown, a sceptre and a mace, but Alice predicted that it was a yo-yo, an umbrella, and a bag of sweets. Alice was correct, and was crowned queen. (PROSE: Once upon a Time Machine)

The Spiridon gambit
Upon arriving on an Earth freighter, the Doctor and Jo were caught up in the escalating tension between planets Earth and Draconia. The Doctor landed his ship in an Earth cargo ship to avoid a collision, but could not properly speak to the crew, as Ogrons boarded it, making off with the TARDIS. Unfortunately, a strange noise caused the human crew to see the Ogrons as though they were Draconians, and they believed the Doctor and Jo had led them onto the ship as spies for Draconia. The two of them were imprisoned on Earth and were unable to convince their captors that they were innocent.

The Doctor was sent to a penal colony on the Moon, where the Peace Party plotted an escape, while Jo was greeted by the Master, posing as a commissioner from Sirius IV and arranged for the release of the Doctor from the penal colony after intervening with a sabotage of the Peace Party's escape plot. They soon discovered that the Master was secretly working with the Ogrons to provoke the two sides into all-out war under the orders of the Daleks, using hypnosound technology to confuse them into thinking humans and Draconians were attacking each other. His plans to kidnap them failed when the ship violated Draconian territory, causing Draconians to seize control of it and bring the Doctor, Jo, and the Master to their home world to face judgement by their own emperor.

Fortunately, the Doctor was able to convince the Draconian Emperor that they were being tricked into attacking humans. He sent the Doctor back to Earth with his son, the prince of Draconia, to convince the President of Earth they had been wronged, but the Master sent the Ogrons to attack them and they captured Jo. Unable to turn back because Earth and Draconia were on the brink of war, the Doctor continued to Earth and explained the deception to its President. He also had to reason with the unyielding General John Williams, who joined the expedition to the Ogron planet, and the group rescued Jo after she managed to resist the Master's hypnosound technology and radioed for help.

The Master anticipated the arrival of the Doctor, having both the Ogrons and Daleks wait for their arrival. He captured the expedition group and promised the Gold Dalek that he would turn over the Doctor to the Daleks for extermination. Fortunately, Jo had pocketed the Master's hypnosound device, and the Doctor used it to frighten the Ogrons into thinking their Dalek masters were terrorising them. In this panic, the Master cornered the Doctor and Jo before they retrieved the TARDIS, pointing a blaster at the Doctor, firing the gun by accident when Ogrons overran him. Though Jo wrestled the gun from the Master as he was swept out of the room by their lumbering bodies, but his shot had grazed the Doctor's forehead and had badly wounded him.

Barely conscious, the Doctor had Jo help him into the TARDIS, where he sent a message to the Time Lords, asking them to pilot his TARDIS and follow the Daleks to their new base. (TV: Frontier in Space) Jo brought the Doctor over to a collapsible bed within the TARDIS console room so he could rest. The Doctor told Jo he would heal, but it would take time. He gave her a tricorder to log anything unusual that happened while he was unconscious, and drifted into a temporary coma.

After the Doctor regained consciousness, he wanted to find Jo to show her he was now healthy. However, Jo had left him to find help and was presumed deceased by a group of Thals she found. He eventually found Jo alive and safe, learning that the Spiridons were a peaceful race forced into violence and experimentation by the Daleks. The group discovered a base with more than ten-thousand Daleks hibernating and buried deep in the ground, and the Doctor figured out they were vulnerable to extreme cold after noticing they slowed down during the nightfall that brought temperatures below freezing on Spiridon. The Daleks were eliminated by using the natural eruptions of liquid ice on Spiridon against them, liberating the Thals, the captive Spiridons, and removing the danger the Dalek army posed to other neighbouring races in the galaxy. (TV: Planet of the Daleks)

After Spiridon
As the Doctor prepared to return to Earth on Jo's request, the TARDIS was drawn to the planet Far, a planet on the far limits of Earth's empire, where the Doctor had once assisted in the construction of a hypergate to help ships travelling long distances. Discovering that the abandoned planet had a platoon of Daleks on it, the Doctor and Jo were separated when they tried to escape, the Doctor falling into an underground chamber while Jo met a member of the local resistance. The Doctor was able to make his way to a Dalek fuelling station run by human slaves who had suffered serious mutations due to exposure to the radioactive substances the Daleks used for fuel, where he met Jickster, the admiral who had once been in charge of Far's defences and was now the least twisted of the Dalek slaves. Jickster and the Doctor were able to steal a Dalek saucer and reactivate the hypergate, allowing them to escape and make contact with an Earth Alliance fleet. Talking with Jickster, the Doctor learned that the Daleks had two secret weapons on Far; a Dalek army in stasis, numbering over a million Daleks, and a giant transmitter that would broadcast a signal enabling the Daleks to turn the attacking Earth fleet into Robomen slaves en masse once they got into range. Although Jo was nearly forced to help set a trap for the Doctor, the Doctor managed to return to Far in his stolen saucer, accompanied by an Earth Alliance strike team. The Doctor managed to reprogram the robotisation weapon to target the Dalek army, with the overload of Dalek instructions causing them to self-destruct, with the Alliance fleet eliminating the rest. (AUDIO: The Conquest of Far)

The Doctor then travelled to Catastrophea, where he stopped Rekar from beating one of the natives. He was put on trial, with Rekar trying to use his power to win the cart over, but was freed, with punishment going to Rekar instead. Because of this, the Doctor became the icon of the revolution and was able to help them when Rekar's men took the TARDIS. He was also given the challenge of stopping Draconians from taking over the planet. In the end, he was able to convince the Draconians to give time for the colonists to evacuate.

A clinic using technology from the future attracted the Doctor's interest when he and Jo learned of two suicides where the victims' bodies had begun "evolving" before they died. The Doctor believed that the Master was involved before the Monk showed himself. When the Doctor confronted the Monk about his plans, the Monk tried to force the Doctor to help Doctor Kurdi perfect her serum by infecting Jo with a lethal virus that could only be cured by Kurdi's process. The Doctor was able to both perfect the serum and a means of negating it, but the situation was complicated when the test subjects in the clinic attacked the others, intending to spread out and convert all of humanity into the 'New Humans'. With the aid of a patient who had developed psychic powers to compensate for his quadriplegic body, the Doctor was able to devise a cure that could be dispersed through the clinic's air circulation system. The Doctor stole the Monk's dimensional buffers before his escape. (AUDIO: The Rise of the New Humans)

After the TARDIS landed in the Lezarata Research Centre, the Doctor went exploring and encountered the Second voice and went into a coma. He placed his mind on the research centre's main tape to avoid the Second voice, when Jo was placed on the same tape, he devised a way to stop the voice by swapping with Jo and tricking the voice into swapping back with Jo in order to get into the TARDIS. When the Voice did that, the Doctor swapped the tapes and erased the tape with the voice. (AUDIO: Ghost in the Machine)

(AUDIO: The Wormery) The Doctor revisited Ronald in Whitby and learnt he’d got a new commission at sea, parting on good terms. (AUDIO: Landbound)

The Doctor returned to Peladon, and found a refugee camp of Ice Warriors displaced from New Mars during the Martian Civil War. Staying to offer his counsel to King Peladon, the Doctor discovered Peladon's spokesman for the refugees, Lord Vaarnak, had been murdered. The next morning, Peladon told the Doctor the legend of the Prisoner of Peladon, and the Doctor realised Lord Axlaar was the murderer of Lord Vaarnak, who had done so because his family had been dishonoured when Vaarnak didn't align with Grand Marshall Raxlyr, and that the Alpha Centauri was hiding Princess Lixgaar in the chamber.

The Doctor took King Peladon, Lord Axlaar and Sslurn, Axlaar's accomplice, to the chamber of the Prisoner. There, the Doctor knocked at the chamber doors, which Centauri opened from inside. The Doctor called for Princess Lixgaar within the chamber, whom Axlaar threatened with his sonic disruptor. The Doctor attacked Axlaar in the chest; the blast of the disruptor hitting Sslurn. Axlaar took aim again at the princess, swatting the Doctor aside, and King Peladon threw himself at him in a blind rage, throwing him out a window. The next day, the Doctor informed Peladon that Izlyr arranged a peacekeeping ship to take the princess to Io. While Peladon spoke with Centauri, the Doctor quietly left in the TARDIS. (AUDIO: The Prisoner of Peladon)

After spending years inventing a device to save Jo from the time distortion, the Doctor travelled to the 2010s and gave the device to Petronella Osgood so that she could track down Jo in the Vortex and pull her out, with only a few moments having passed for Jo and Osgood.

While touring Antarctic Weather Research Station 12 with Lieutenant Davis, the Doctor saw Clegg, a crewmember of the USS Jefferson, enter the research station, mentioning the Jefferson had gone and "doors in the ice" before dying. When the Doctor and Davis returned from their failed search of the nuclear submarine, they found the weather station had been destroyed. Following the tracks of a sledge, they found a giant doorway into a glacier, where the Daleks had taken the Jefferson after they had patiently waited centuries for the human race to advance to a point where the Daleks could use humankind's technology against them.

After the Doctor failed to warn Sydney in time, the Daleks launched Polaris missiles from the submarine into the harbour, destroying Sydney Harbour Bridge. Pretending to be mind-controlled humans in Dalek-occupied Sydney, the Doctor and Davis sneaked into a Dalek factory and discovered the Daleks planned to convert the human race into Daleks. The Doctor escaped into the harbour and climbed what remained of Sydney Harbour Bridge to draw the Jefferson, and the Daleks on board closer. Davis threw a live cable at the submarine, killing the Daleks on board and stopping their invasion. (COMIC: *Sub Zero) In a response to the Doctor's defeat of them, the Daleks placed a time vector around the TARDIS.

The Doctor met Harry Trant, also stranded, and they worked together to get eaten by a parasitic amoeba on the planet's surface, which in turn was eaten by the planet. They reached the TARDIS in the stomach, and the Doctor materialised at the heart, telling Harry to shoot it. He did so hesitantly and the planet screamed as it died. The Doctor told him that, though killing was not a pleasant duty, the planet needed to be killed because of its size, and then took him to his home planet. (COMIC: The Hungry Planet)

The Third Doctor was taken out of his timezone by the Father of Time to partake in "the Final Test". He was brought to a TARDIS control console room from his future alongside his second, fourth, fifth and sixth incarnations, and told that Time had disassembled the control console and set the TARDIS on a course for the heart of the sun, with the Doctors' only hope being to reassemble the control console. Unable to achieve the task due to their bickering, the Doctors were saved when the First Doctor united them in reversing time itself with their pooled temporal powers.

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

Meeting Sarah Jane Smith
Journalist Sarah Jane Smith impersonated her aunt, virologist Lavinia Smith, to gain access to a UNIT research centre. Top scientists were being held there in protective custody while the Doctor investigated the disappearances of their colleagues.

The missing scientists had been kidnapped by a Sontaran commander named Linx, and taken to England in the Middle Ages, where they were working under hypnosis to repair his crashed spaceship. The Doctor helped return the scientists home with Linx's osmic projector. The premature take-off of the Sontaran ship caused the destruction of Irongron's castle, along with the anachronistic weapons Linx had provided to Irongron. (TV: The Time Warrior)

The Doctor, Sarah, Jeremy Fitzoliver and the Brigadier went to Space World, a new amusement park, to investigate a death that had occurred nearby. The park was run by Naglons disguised as humans, who wanted to hypnotise the humans to do their bidding. The aliens left Earth, but not before they captured Sarah and Jeremy. The Doctor and the Brigadier travelled to Parakon to retrieve them. (AUDIO: The Paradise of Death)

Exploits with Sarah
During a visit to Varium III, the Doctor and Sarah were accused of sending down streaks of fire that had destroyed the crops of the planet, and were sentenced to death by Marshal Zona. However, the Doctor was able to convince Zona to give him time to help, and he found out that a rare storm on Varium III, combined with its stable climate and weak sun, had awoken a virus that had wiped out the vegetation. After some failed trials, the Doctor discovered that sodium chloride was the key to stopping the virus, and helped Zona build pumps to pump seawater from the nearby ocean onto the land, and also taught the people how to fish to give them a different source of food. (PROSE: Scorched Earth)

A large cloud of deadly gas created from the destruction of a star nearly destroyed Earth, but the Doctor was able to discern that it was not natural, and was, in fact, an attempt by the Zircon to wipe out Earth. The Doctor and Sarah alerted the Brigadier and the Prime Minister. The Doctor was able to use the satellites of Earth to set off an explosion to destroy the cloud and the Zircon. (COMIC: Doomcloud)

The Doctor and Sarah then accidentally travelled into a parallel Earth where they were human criminals. They were able to escape by travelling into a primitive Earth, where they left their counterparts, returning home. (COMIC: Who's Who?)

The Doctor and Sarah arrived in 1970s London to find that it had been evacuated because of dinosaurs. The dinosaurs were being brought to London through time eddys in a plan to revert Earth to a pre-technological level. The masterminds behind the Operation Golden Age scheme, Whitaker and Charles Grover, were accidentally transported to pre-historic Earth. (TV: Invasion of the Dinosaurs)

Attempting to travel to Florana, the Doctor and Sarah arrived at Cerulean, which was being attacked by missiles from the planet Sedna. The Doctor was able to create a barrier, and the aliens soon began to speak of peace, requesting that the Doctor represent the planet Cerulean, but, before he could, he detected a future version of his TARDIS about to crash into his and left. (PROSE: Neptune)

Still en route to Florana, the TARDIS ran afoul of a device that neutralised its power, causing it to crash on the planet Exxilon. Forced to postpone their travel plans, the Doctor and Sarah were met by the primitive natives with aggression. Their issues compounded when they met other parties afflicted by the same device. The Doctor encountered Marine Space Corps members seeking Parrinium, a cure for a space-plague, who were starting to grow restless and fearful after losing some of the crew's commanders, which left Dan Galloway in charge and on edge. The Daleks also landed for the same purpose. The Doctor and the Daleks discovered the Great City of the Exxilons, a large city with a power-disrupting tower preventing technology from working. The natives had become victims of their own technology when it gained sentience and drove them out of their city. This forced them into the wilderness with no means of technology, where they remained for so long it caused them to regress to more primitive ways and worship the city that destroyed them.

However, as the Doctor and Sarah encountered the brutish natives, they also ran into a faction that wished to destroy the city, and befriended Bellal. The Doctor listened to the plight of Bellal's people and agreed to put an end to it with his help. With Bellal's help, he sought to disrupt their city's functions and remove the power-disrupting facility, though it required him and the humans to infiltrate the city's defences and get through several puzzles. Although the Daleks were incapable of using their gunsticks and were left in a rare state of vulnerability that took its toll when the Daleks where picked off by Exxilons and the city's traps alike, they resorted to using ordinary guns to coerce the Doctor and company into following their orders. The Daleks ordered humans to place bombs around the city's central tower to destroy it. The city was destroyed, as was the Dalek space ship, when Galloway chose to atone for his ruthlessness as the acting commander by sacrificing his life to manually detonate bombs placed aboard the vessel. Though the Marine Space Corps could now retrieve their cure on future missions to Exxilon, the Doctor regretted having to destroy the Exxilon's city and lamented the loss of one of the universe's wonders. (TV: Death to the Daleks)

The Doctor, Sarah, Jeremy, and the Brigadier travelled to San Stefano Minore and encountered ghosts crossing from Null-Space to Earth. (AUDIO: The Ghosts of N-Space)

The Doctor and Sarah finally arrived on Florana in 5968, just as the Chelonian Empire was to sign a treaty with humanity. There, Sarah overheard two Chelonians discussing how one had poisoned the emperor's drink, and went to warn the delegates. The Doctor noticed the emperor's strange actions and poured a bucket of water down his throat, thus removing the poison. (PROSE: The Hungry Bomb)

The Doctor and Sarah visited Bob Dovie at 59A Barnsfield Crescent in Totton, Hampshire on 23 November 1963, (AUDIO: The Light at the End) and defeated the Android maker of Calderon IV. (PROSE: The Android Maker of Calderon IV)

The Doctor and Sarah were called back to Earth by Liz, who herself had been summoned back to UNIT due to the Brigadier acting strangely. The Doctor discovered that the Brigadier had been possessed by a Remoraxian, a species that wanted to flood the world to allow them to colonise, and built a de-remorator to remove the Remoraxian from the Brigadier. The Doctor, Sarah, Liz and the Brigadier went to the nearby UNIT seabase, along with Agent Paul of the CIA, where the Remoraxian Prime was orchestrating its plot to flood the world. Discovering that the American government had authorised the nuclear bombing of Great Britain to stop the threat, the Brigadier persuaded the Remoraxian Prime that the Americans would follow through with the attack, and the Remoraxians left Earth, ending the threat of the bombs. As the Doctor summarised the situation, Liz, Sarah and the Brigadier were abducted by Adam Mitchell. (COMIC: In With the Tide) The Doctor quickly ran off to rescue them. (COMIC: The Choice )

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

The Doctor and Sarah thwarted an invasion of Dahensa in London by setting up a sonic manifold feedback loop over the city from the Post Office Tower. (COMIC: Invasion of the Scorpion Men)

The Doctor and Sarah then travelled to the planet Hezrah, where the people worshipped the Eternal Machine, which would send chosen citizens to the stars. The Doctor revealed that the machine was actually an alien that would slowly touch and kill the citizens, in order to gain power. The creature's followers grew angry at the creature and set it ablaze, killing it. (PROSE: The Discourse of Flies)

The Game of Rassilon
While taking a ride in the country in Bessie, the Doctor was saved from the Great Intelligence by Clara Oswald, (TV: The Name of the Doctor) and was then captured by a Time Scoop and taken to the Death Zone on Gallifrey. There, he encountered an older Sarah Jane Smith, who at first was confused by the sight of him as she had witnessed his regeneration and had already parted company with his next incarnation. They travelled to the Tomb of Rassilon, where the winner of the Game of Rassilon would be given immortality. On the way, the Doctor met, who claimed to have been sent by the Time Lords to help him, a claim the Doctor did not believe, confiscating the Seal of the High Council from him, under the assumption that it was stolen, and believing instead that the Master was behind everything, a claim he felt was confirmed when thunderbolts suddenly rained down on them, one of them hitting Bessie and forcing he and Sarah to walk. The Doctor and Sarah also encountered a group of Cybermen and a Raston Warrior Robot; fortunately, the two of them were able to sneak past while they did battle, the Cybermen quickly getting slaughtered.

Using stolen climbing utensils from the Raston Warrior Robot, the Doctor and Sarah climbed to the top entrance to the tower. Inside the tower, the Doctor encountered illusions of Liz Shaw and Mike Yates, and eventually reached the tomb, where the Doctor joined with his first and second incarnations to study the writing by Rassilon's tomb, and open the teleportation systems. The Fifth Doctor arrived, under the control of Lord, 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, he was turned to stone and became trapped within a sarcophagus. The Doctor was soon after returned to his time zone with Sarah Jane by Rassilon. (TV: The Five Doctors)

Time alone
The Doctor helped many colonisers in the far future find a new planet, (COMIC: The Wanderers) and then attended the funeral of Alistair Gordon Lethbridge-Stewart with his other incarnations, (PROSE: The Gift) where he comforted Liz Shaw during the burial. (PROSE: Shroud of Sorrow)

The Third Doctor was summoned by his first incarnation, who required the aid of one of his future incarnations to escape a castle in medieval England, where he had been entrapped by knights thinking he was holding Lady Mary hostage in his TARDIS. After the Fifth Doctor lost the game that chose who would face the knights, he explained the situation to them and the Doctors were permitted to leave. (PROSE: Five Card Draw)

Final exploits
The Doctor returned to Peladon with the intent of reuniting with King Peladon, but accidentally jumped fifty years ahead of his last visit. By then, Peladon had died, with his daughter, Queen Thalira, ruling under a period of dissent, and an ongoing labour dispute between Pel nobility and the Pel miners worsened when apparitions of Aggedor attacked and killed several miners. Following an uprising by the oppressed miners, and distrust from the queen's chancellor, Ortron, regarding who the Doctor and Sarah had sided with, the two were sent to face the judgement of the Aggedor, whom the Doctor calmed with a Venusian lullaby. By Peladonian law, he and his companion were exonerated of any charges placed against them. With the situation worsening, Alpha Centauri summoned for assistance from the Federation, and they sent in Ice Warriors to ensure production. The Ice Warriors' commander, Azaxyr, threatened to kill hostages if the miners refused to work, and the Doctor brought the miners and ruling class together to fight the Ice Warriors.

Following a long series of disputes, the Doctor, Sarah and the Peladonians learned the planet was under siege by Eckersley, a Federation defector seeking to manipulate the people into giving up their world's stores of trisilicate for his own gain. One of the miners, Ettis, attempted to wipe out the whole of them by firing a sonic lance on the Peladonian citadel, duelling the Doctor and subduing him long enough to use the device. Having planned against this, Azaxyr had placed a self-destruct mechanism on the lance, which killed Ettis when he activated it. After recovering from his duel, the Doctor found the apparitions of Aggedor were being created by a machine in the mine that Eckersley had protected with a security system, assaulting the Doctor's senses when he turned it on. When Eckersley cranked up its effects high enough to kill him, the Doctor used sensory withdrawal to block out the attack and feign death until Sarah could rescue him. With the cooperation of Gebek, leader of the miners, and Thalira's forces, Eckersley and the Ice Warriors were wiped out. Sadly, the Aggedor was a victim of the battle between the groups when he and Eckersley killed each other, upsetting the Doctor.

In the aftermath of the uprisings, the Doctor helped bring about a new era of peace to Peladonian society and Sarah, seeing how Thalira was treated due to her gender, ensured that the laws of Peladon would view the queen as a true ruler. (TV: The Monster of Peladon) The Doctor and Sarah then retrieved Sputnik 2 and buried Laika, the first space traveller from Earth, on the distant planet Quiescia. (PROSE: Alien Bodies) After this, Sarah requested that they return to Earth. (PROSE: Interference: Shock Tactic)

Afterwards, the Doctor and Sarah travelled to London in December 1952, where the Doctor discovered that poisonous smog was killing the citizens. He discovered that it was created by two Xhinns, a humanoid alien race that were usually peaceful, who wanted to cover their tracks. With help of the local gangsters, he was able to create a time bomb, which caused their ship to age greatly and disintegrate. (PROSE: Amorality Tale)

At Christmas, the Doctor and Sarah travelled to 1822 New York, where they met Santa Claus. As they talked, they did not realise that they were being watched by Clement C. Moore, who then settled down to write "Twas the Night Before Christmas." (PROSE: A Visit from Saint Nicholas)

Visiting Coal Hill School to drop off flowers for the flower garden, the Doctor told Sarah of the time his first incarnation fought off Space wolves with Shivani Bajwa, but refused to admit to her that the First Doctor had purposely barred fleeing people from entering the school. (PROSE: Doctor Who and the Horror of Coal Hill)

The Doctor and Sarah then met a man named Isaac, a composer and future companion of the Doctor's. He was stalked by two grey figures, and eventually committed suicide. The Doctor attempted to investigate, but was stopped by the bowler hat Time Lord, who informed him that he had to wait until he encountered the events himself. (PROSE: An Overture Too Early)

A slow demise
The Doctor took the Brigadier to see a travelling performance show, where he observed a powerful clairvoyant, Professor Herbert Clegg. He arranged for the professor to meet him in UNIT HQ, where he looked into the source of Clegg's abilities. Before his experiment could begin, he was presented with a package; Jo had sent her Metebelis crystal back to him after a group of Indian porters cited it would bring them bad luck and refused any further association with her and Cliff unless she discarded the crystal. However, Clegg looked into it, causing his psychic abilities to increase and show him a frightful image of extraterrestrial spiders, which gave him a fatal heart attack.

Reunited with Mike Yates, the Doctor and UNIT discovered mysterious goings-on at a meditation retreat run by Tibetan monks were linked to a colony of monstrous spiders on Metebelis III. Here, he ran into his old mentor, K'anpo Rimpoche, who suffered an attack from the spiders and regenerated. The spiders sought the Doctor's crystal and began attacking, possessing, subjugating and killing anyone who stood in the way of them reclaiming the crystal. The Doctor realised that the act of taking it in the first place was a deadly oversight from the beginning, and was told by K'anpo he had no choice but to return the crystal, which would spell his doom.

To save his companions, his teacher, and the whole cosmos from them, the Doctor exposed himself to lethal levels of radiation to destroy the web of the Great One. He allowed the Great One to repossess the crystal, which gave her infinite psychic power, unaware this would be too much for her to bear. The Great One and the Eight Legs linked to her could not handle the limitless power and were destroyed. The Doctor limped to his TARDIS and escaped Metebelis III, horrendously irradiated. (TV: Planet of the Spiders)

The Doctor was stuck wandering around the Time Vortex for ten years, the radiation slowly eating away at his body. The effects became so severe that he could not even reach the TARDIS console, and was doomed to simply wait until the TARDIS landed of its own accord. (PROSE: Love and War) During this time, he was taken prisoner by a corrupt being called Tremayne in East Berlin. Even though he was enduring a painful death, the Doctor worked alongside Edward Grainger and stopped Tremayne and the Logos from rewriting the history of the whole cosmos. (PROSE: Ancient Whispers)

Death
"No, don't cry. While there's life, there's... huh..."

- The Third Doctor's last words

When the TARDIS finally deposited the dying Doctor back on Earth, he promptly collapsed in his UNIT lab next to Sarah Jane and the Brigadier. Looking at Sarah Jane, he tried comforting her, but expired before he could finish his dying words. K'anpo Rimpoche's psychic projection reappeared before Sarah Jane and the Brigadier, and promised the two that the Doctor would be all right, deciding to give the Doctor "a little push" to help his cells begin a regeneration, then vanished and told Sarah Jane and the Brigadier to "look after him". The Doctor then started breathing again and regenerated into his next incarnation. (TV: Planet of the Spiders)

Perversion of history
Several regenerations and hundreds of years later, the Doctor's eighth incarnation was imprisoned and brutally tortured in Saudi Arabia while investigating the activities of the Remote. In a delirious state, the Doctor created a time equation with his own blood. Due to the interference of Faction Paradox, this connected the Eighth Doctor to the Third Doctor's TARDIS. (PROSE: Interference: Shock Tactic)

After the Third Doctor and Sarah buried Laika on Quiescia, (PROSE: Alien Bodies) Sarah requested that they return to Earth. Half an hour into this trip, the Third Doctor discovered a new and mysterious door within the TARDIS, which led to his eighth incarnation's prison cell. The future Doctor tried to warn the Third Doctor about Faction Paradox, realising too late that he wasn't supposed to know of them until his fourth incarnation; he then warned his past self against being diverted from his destination. Shocked by this scene, the Doctor returned to the console room, where Sarah Jane stood, shocked, as she saw the walls begin bleed. As the Eighth Doctor had warned, the TARDIS then landed on the planet Dust during the War in Heaven, on the same day when I.M. Foreman's Travelling Show arrived and the Faction Paradox warships approached the planet. (PROSE: Interference: Shock Tactic)

The Doctor resolved the Remote invasion, escaping death at the hands of Father Kreiner, and resolved the apparent paradox of Foreman's original encounter with his future selves. However, as he and Sarah prepared to leave in the TARDIS, he decided to visit Foreman's final incarnation and convince it to infuse with Dust's ecosystem and transform the dead world into a lush green one. Satisfied with the outcome of his time on Dust, the Doctor was on his way to rejoin Sarah in the TARDIS when he was confronted by Magdelana Bishop. Convinced that it was the only way to protect her world from future invaders, Magdalena shot him in the chest with a shotgun and left him for dead in the street. As he began to regenerate, Sarah dragged him back to the TARDIS to return to UNIT.

As the Doctor's immune system was compromised by regeneration, the Faction's biodata virus bonded to his biodata. The Doctor still regenerated into his fourth incarnation, and history continued much like it did before the change, but by the end of the Doctor's eighth incarnation the virus would corrupt him into a member of the Faction. (PROSE: Interference: The Hour of the Geek) As part of this process, the Eighth Doctor lost his shadow. (PROSE: Unnatural History)

However, the TARDIS took the infection and fragments of the original timeline into itself, preserving the essence of the Third Doctor who didn't die on Dust. (PROSE: The Ancestor Cell) Even after the TARDIS' near-destruction on Avalon (PROSE: The Shadows of Avalon) and subsequent corruption into the Edifice, the dust ghost of this original Third Doctor retained a degree of control over the ship's defences. Over his five millennia in the ship, he trained its spiders to be his scouts and lookouts. Finally, with the Edifice hanging over Gallifrey during the Faction Paradox invasion, the Third Doctor confronted Grandfather Paradox and guided the Eighth Doctor to use the TARDIS' defence systems to destroy Gallifrey and Kasterborous, forcing the universe to choose one of the two timelines.

The Eighth Doctor was uncertain which timeline would become real; afterwards, his shadow reappeared, so Compassion initially told Fitz Kreiner that the Doctor's visit to Dust and the War in Heaven had been unwritten from history. (PROSE: The Ancestor Cell) However, Compassion would later become a major player in the War on other Gallifreys. (PROSE: The Book of the War, Of the City of the Saved..., Warring States, The Brakespeare Voyage, AUDIO: In the Year of the Cat) When the Eighth Doctor eventually regained contact with the greater universe, history had been rewritten so that Gallifrey had never even existed, (PROSE: The Adventuress of Henrietta Street) suggesting that the War had not been erased, but actually continued and ended in some other way. (PROSE: The Book of the War, The Story So Far...) Eventually, Gallifrey was restored to the universe, though the Time Lords would eventually find themselves fighting a war against the Dalek Empire. (TV: The Night of the Doctor) A history of the universe recounted that the Third Doctor regenerated after the battle with the Eight Legs and the Great One, (PROSE: The Whoniverse) implying that the Eighth Doctor had been successful in restoring that part of history. (PROSE: The Ancestor Cell)

Post-mortem
When under attack by a space amoeba, the Fourth Doctor briefly turned back into his third self. (COMIC: Timeslip)

In a dream garden occupied by the Doctor's previous incarnations, the Third Doctor made additions to the garden, including trying to add a statue to it, before the notion was rejected. (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. The Doctor was forced to use his morphic instability to mentally regress back to his third persona when he found himself requiring the Third Doctor's skills at hand-to-hand combat to act as a gladiator in this pocket reality, essentially letting the Third Doctor's persona control his body when he was required to fight. (PROSE: State of Change)

In a bid to detach the Funhouse from the TARDIS in the time vortex, the Sixth Doctor bound 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)

On another occasion, the Seventh Doctor used the TARDIS telepathic circuits to bring forth the memory of his third incarnation when he felt that the Third Doctor's technical expertise would be useful to disarm a dangerous bomb. The Doctor described his third persona as vain and suggested he wouldn't have liked being trapped in the seventh incarnation's body. (PROSE: Timewyrm: Genesys) However, this allowed the Timewyrm to infiltrate the Doctor's mind, and set up Anthony Rupert Hemmings in the portion of the Doctor's subconscious occupied by the Third Doctor's persona. The Doctor offered little resistance, distracted by the discovery that the dictator of the Inferno Earth was his direct counterpart. When the Seventh Doctor and Ace entered the Doctor's mind, the Seventh Doctor was able to help the Third Doctor gather the strength needed to expel Hemmings from their mind. No longer a prisoner of his own making, the Third Doctor began to rebuild the Doctor's subconscious mind. (PROSE: Timewyrm: Revelation)

When the Tenth Doctor was confronted by Es'Cartrss within the TARDIS' Matrix, he summoned the Third 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 Third 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 Third Doctor, interrogating him over the crimes. When he offered the rational 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 was attacked by the Then and the Now on Lujhimene, the Third Doctor was among the incarnations seen as the Doctor's timeline was almost destroyed. (COMIC: Running to Stay Still)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Third Doctor, appeared inside it to defend themselves as well. When the Second Doctor debunked auditor Sondrah's accusations of his menace by bringing up the fixed points in time, the Third Doctor continued the protest by proclaiming he stopped outside interference from the likes of the Daleks, the Cybermen and the Sontarans from affecting the Earth's progression. 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)

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 Third 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 Third Doctor. (AUDIO: The Lost Magic)

Undated adventures

 * River Song met the Third Doctor, and recounted in her diary that he was one of her favourite incarnations of the Doctor and they "had a lot to talk about". She had his memory wiped with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)
 * On a Thursday in the summer of 1966, the Third Doctor visited Andy Warhol to have his face added to a portrait of eleven incarnations of the Doctor. (PROSE: The War of Art; COMIC: The Girl Who Loved Doctor Who)
 * The Third Doctor had his portrait drawn by John Singer Sargent. The Fifth Doctor would recount that he did a "very good job". (AUDIO: Time in Office)
 * The Third Doctor once spent a summer in the Cotswolds on a narrowboat with Mary Berry. (PROSE: Twice Upon a Time)

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. Without the Brigadier's knowledge, the Doctor and River would meet up to practice one-legged Venusian aikido while blindfolded on a tightrope. (AUDIO: Someone I Once Knew)

In an alternate timeline created by using the Chronovore Artemis, (PROSE: No Future) the Third Doctor was killed by Morka during his confrontation with the Silurians, resulting in humanity being decimated as the Silurians attempted to return Earth to its original state. (PROSE: Blood Heat)

In one possible timeline envisioned by the Nexus, the Third Doctor decided to remain on Earth after his exile, settling down an old house with a garden. When the Ice Warriors invaded in 2010, the Doctor surrendered on Earth's behalf, with the Ice Warriors ruling the Earth Empire peacefully, assisting the humans and Silurians in combating the Rutan Hosts and the Daleks, but largely leaving them to their own devices, with Earth eventually becoming a nature reserve that shunned war. The Third Doctor was able to live for a thousand years on Earth without regenerating, though became wheelchair bound, and was aware that he was only a "copy" of the Doctor. (PROSE: So Vile a Sin)

In an alternative timeline where his exile never ended, the Doctor remained in Britain for forty years, forming a working relationship with PM Melanie Bush for over twenty years. However, he eventually betrayed the United Kingdom when it was invaded by the Cybermen in 2010, as he felt that Britain's best efforts against the Cybermen were destined to be useless. The Cybermen partly converted the Doctor and restored his ability to travel in time. (PROSE: The Quantum Archangel)

Averted timelines


When the Cybermen allied with Rassilon to take over history, (COMIC: Supremacy of the Cybermen) the Doctor encountered a time distortion during a battle with that ended with the Master being cyber-converted. (COMIC: Prologue: The Third Doctor) This timeline was eventually unwritten by Rassilon and the Twelfth Doctor. (COMIC: Supremacy of the Cybermen)

Undone events
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 Third Doctor, along with his first and second 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)

Other references
Travelling through the caves of the Death Zone to save Borusa from the Dark Tower, the War Doctor and Cinder found various cave paintings which the Doctor speculated were depictions of himself throughout his lives, some of which he failed to recognise. One of the paintings depicted a figure "with bouffant white hair and a cape being chased by a silver robot". (PROSE: Engines of War)

Personality
A champion for peace and justice, (TV: Colony in Space) who "hardly ever" lied, (TV: The Time Warrior) the Third Doctor valued his freedom, (TV: Frontier in Space) believing "the collection of the simplest animal lifeforms [to be] a dubious enough pursuit in itself", but that "the collection of civilised [and] intelligent beings [was] a positive crime", (TV: Carnival of Monsters) sympathising with such caged creatures due to his experience as an exile on Earth. (AUDIO: Walls of Confinement) He was also more of a show-off than his predecessors, often putting himself at the centre of attention when his plans and contraptions worked accordingly. (TV: Spearhead from Space) Liz Shaw believed he only really required an assistant to "pass [him] [his] test tubes and to tell [him] how brilliant [he was]." (TV: Terror of the Autons)

Having "an air of natural authority", (AUDIO: A True Gentleman) he was far more assertive than his preceding incarnations, (TV: Spearhead from Space) with less patience for protocols such as visitor's passes, (TV: The Ambassadors of Death) and strove to maintain his independence while working for UNIT, such as by ignoring the Brigadier's summonings. (TV: TV: Doctor Who and the Silurians) He also disliked having to answer to the Time Lords, maintaining that he worked only for himself. (TV: Colony in Space, Day of the Daleks) However, he could be more passive when it came to rescues, not questioning the falsehoods his allies would give when coming to his aid, (TV: The Dæmons) and, while he disliked having to work for them, he would use his association with UNIT as a means of getting his way. (TV: Doctor Who and the Silurians, The Mind of Evil, The Green Death)

Authoritative, yet rebellious, the Third Doctor always favoured peace and diplomacy above violence and aggression, though this lead him to clash with stalwart military-minded individuals who chose rules over morality, with figures such as the Brigadier often being a thorn in his side, especially when a particularly aggressive influential had a greater majority of imprudent people on their side. The Doctor held a strong disgust towards these people, who were any combination of stubborn, selfishly goal-driven or close-minded, and would be further outraged if they refused to listen to him, ignored his protests or went to absurd lengths just to dodge the risk of being proven wrong, especially when they acted antagonistic and undiplomatic. (TV: Doctor Who and the Silurians, Inferno, The Mind of Evil, The Claws of Axos, Day of the Daleks, The Sea Devils, Frontier in Space, The Green Death) If unsatisfied with someone's handling of a situation, however, the Doctor would step in forcefully and take charge, (TV: Inferno) but, if diplomacy outright failed, he reacted in a subdued manner, giving a scathing and virulent dressing down to the foolhardy individuals that destroyed a bid for peace and order. (TV: The Mind of Evil, The Green Death)

Feeling akin to "a shipwrecked mariner" while stranded on Earth without a working TARDIS, (TV: Inferno) the Third Doctor spent a lot of his time trying to escape his exile, either by tricking others into helping him unlock his TARDIS' capabilities, (TV: Spearhead from Space, The Claws of Axos) by trying to repair the circuits himself, (TV: The Ambassadors of Death, Inferno, Colony in Space, Day of the Daleks, The Mutants) or by stealing parts from other TARDISes. (TV: Terror of the Autons) His desire to escape would cause him to become overconfident at the first sign of liberation, though he was often forced to humble himself once he realised he was still trapped. (TV: Spearhead from Space, Inferno, Terror of the Autons, The Claws of Axos) After he threatened his eighth incarnation with the Master's TCE for a working TARDIS, the Doctor decided to remain in his exile of his own free will, (PROSE: The Eight Doctors) eventually coming to see UNIT as a "new-found family", which he continued to visit after his exile was lifted. (PROSE: The Shadows of Avalon)

Having a distain for bureaucracy, (TV: The Ambassadors of Death, Colony in Space, The Sea Devils) he was rebellious against authorities that were openly hostile towards him. (TV: Inferno, Invasion of the Dinosaurs)

While he was very hospitable with fellow intellects of his calibre, (TV: Spearhead from Space, The Green Death) the Doctor would get rude and dismissive with those he saw as beneath his intellectual prowess, particularly when they interfered in his work. (TV: Terror of the Autons, The Curse of Peladon, The Sea Devils, The Three Doctors) However, he could not bring himself to be dismissive of them in the face of their kindness, (TV: Terror of the Autons) and would not dismiss someone who others looked down upon for their poor intelligence. (TV: Planet of the Spiders) At times, however, the Doctor could become argumentative and needed to be defused in order to establish fluid communication with people. (TV: The Ambassadors of Death, The Dæmons)

Never judging by appearance, (TV: Carnival of Monsters) the Doctor would eagerly extend the hand of friendship to any new species he encountered, (TV: Doctor Who and the Silurians, Colony in Space) attempt to embrace the customs of the cultures he visited, (TV: The Time Warrior) and would reserve his judgement on people until he had all the facts, (TV: Day of the Daleks) though his opinions on species as a whole could be clouded by past experiences with specific members. (TV: The Curse of Peladon, Death to the Daleks)

While he would chide others for having a "childish attitude", (TV: Inferno) the Doctor himself admitted a liking for "being childish", such as by enjoying the prospect of battling villains, (TV: Terror of the Autons) even prolonging a swordfight with the Master out of sheer enjoyment. (TV: The Sea Devils) He also had no problem interrupting lecturers when he disagreed with what was being said. (TV: The Mind of Evil) By his own admittance, it was "impossible" for him to admit when he was wrong. (TV: Carnival of Monsters)

The Third Doctor had a passion for science and gadgets that caused him to drown out other people when he was invested in his work. (TV: Doctor Who and the Silurians, The Time Monster, The Green Death, Invasion of the Dinosaurs, Planet of the Spiders) He also loved his vintage car, Bessie, almost as much as he loved his TARDIS, fixing it up and giving encouraging pats and kisses, (TV: TV: Doctor Who and the Silurians, The Five Doctors) and even preventing the Brigadier from shooting when Bessie was in the line of fire. (TV: The Dæmons)

In moments of leisure, the Third Doctor could be found tinkering away at his car, (TV: Doctor Who and the Silurians, The Dæmons) undergoing a scientific experiment, (TV: Terror of the Autons) visiting events to indulge his "scientific curiosity", (TV: The Mind of Evil, Planet of the Spiders) or building a new gadgetry contraption. (TV: The Green Death)

Though he desired a "quiet life", (TV: The Monster of Peladon) the Doctor craved in seeing the wonders of the universe, (TV: Colony in Space) with his favourite planets being Metebelis III, (TV: Carnival of Monsters) and Florana. (TV: Invasion of the Dinosaurs)

He enjoyed gorgonzola cheese, wine, (TV: Day of the Daleks) and ice cream. (PROSE: Dr. Third) His liking of tea was so great that he allowed the UNIT tea lady unrestricted access to his private laboratory, (TV: Terror of the Autons) while also preferring lime to lemon in his drinks. (PROSE: Verdigris)

Always trying to find the "good in everyone", the Third Doctor was an eternal optimist with a belief that life would always continue in some form, (TV: The Dæmons, The Mutants, Frontier in Space) often comforting people when all hope seemed lost to them, (TV: The Time Monster, Frontier in Space, Planet of the Daleks, Planet of the Spiders) believing that "nothing [was] impossible" as long as there was an answer to find. (TV: Carnival of Monsters) He considered the greatest virtues in humanity as being "kindness, compassion, humour, friendship, [and] generosity". (WC: U.N.I.T. On Call)

A strong believer in fairness, the Doctor was reluctant to release back into the cosmos, (TV: The Mind of Evil) but argued against executing him at his trial due to his the belief that the Master was capable of redemption, (PROSE: Doctor Who and the Sea-Devils) and also bargained for him to be spared "an eternity of torment" from Kronos. (TV: The Time Monster) He was also saddened by the fate of Omega. (TV: The Three Doctors) He strove to find a peaceful alternative to the more violent methods that others' held in resolving a crisis. (TV: Doctor Who and the Silurians, The Sea Devils)

Not believing in the supernatural, the Doctor put his faith in science, believing that a scientific explanation could be found to anything unexplainable. (TV: The Dæmons) He saw "absolute power" as "evil", (TV: Colony in Space) and would turn away supreme powers when they were offered to him, (TV: The Dæmons, The Five Doctors) instead focusing on obtaining the "power of friendship", which he considered to be "real power". (COMIC: The Kingdom Builders) He thought that "superior intelligence and senseless cruelty just [did] not go together", (TV: The Three Doctors) and once voiced the belief that "rules were made for breaking". (COMIC: The Forgotten)

While the place where he felt "most at home in the whole universe" was in his TARDIS, (AUDIO: Terror of the Master) the Doctor also saw "time and space" as being his "home", (TV: The Shrink) but also held a similar sentiment for his UNIT laboratory. (TV: Planet of the Spiders)

While very little managed to scare him, (TV: Planet of the Spiders) the Doctor had a fear of seeing a planet being overwhelmed by fire and destruction (TV: The Mind of Evil) after seeing the Inferno Earth being destroyed in volcanic ash. (TV: Inferno)

While he was unafraid to use deadly force if it was "the only way" to end a fight, (COMIC: The Labyrinth) the Doctor was reluctant to destroy something if it had a trace of intelligence, likening it to murder, (TV: Terror of the Autons) though he would end a life if it "had to be done". (COMIC: The Hungry Planet) He felt nervous about his capabilities with a gun, (TV: The Mind of Evil) even when he proved effective with one. (TV: Day of the Daleks)

While he had a dislike for machines, (TV: The Green Death) he held a particular distain for computers, (TV: The Ambassadors of Death) believing them to be "stupid", (TV: Frontier in Space) but noted that they could be useful tools. (TV: Inferno)

The Third Doctor owned a country house thirty miles from Thisis, that he had bought with his UNIT wages. He decorated the dining room with French windows, robin's egg blue décor, a red wood dining table, and portraits of his past incarnations. There was also a room decorated in deep underwater blue, with a collection of blue Chinese ginger jars containing holograms of planets and creatures, including a Stranovitican. He had a laboratory in the house, which, though messier, was better equipped than the UNIT lab. He had the drive lined with marble statues of various mythical beasts, including a faun and a Minotaur. He also kept a pet ginger cat in the house, and had a huge yellow teapot in the kitchen. (PROSE: Verdigris)

The Third Doctor had a noticeably antagonistic relationship with the Second Doctor, their personalities so different that they seemed incapable of working together amicably without the authoritative presence of their first incarnation. (TV: The Three Doctors, The Five Doctors) He also disliked the Eighth Doctor, as he blamed him for the advice he gave the Second Doctor that resulted in his forced regeneration and exile. (PROSE: The Eight Doctors)

The Fourth Doctor considered his immediate predecessor to be "an incorrigible show-off", (PROSE: Categorical Imperative) while the Fifth Doctor described the Third Doctor's behaviour as "arrogant" and "overbearing", although he admitted that he matured over time. (PROSE: Deep Blue)

While the Sixth Doctor told Peri Brown that his third incarnation was "more interested in axle grease and looking in the mirror" than in reading great literature, (AUDIO: Year of the Pig) he was willing to acknowledge the Third Doctor's superior skill with a sword, even if he dismissed him as having an "unusual dress sense". (PROSE: State of Change) The Seventh Doctor also acknowledged that the Third Doctor's technical skill outstripped his other incarnations. (PROSE: Timewyrm: Genesys)

While the Eighth Doctor looking down at his third incarnation, (COMIC: The Pictures of Josephine Day) he still acknowledged him as an "elegant dandy struggling bitterly against the chains of his exile but unable to resist defending the planet that had become his prison". (PROSE: The Eight Doctors)

During to his exile on Earth, the Third Doctor was often frustrated about his mistreatment and became disrespectful from time-to-time, often bickering with Brigadier Alistair Gordon Lethbridge-Stewart due to not agreeing with his military methods. (TV: Doctor Who and the Silurians, Inferno, Terror of the Autons, The Claws of Axos) However, the Doctor also held a great respect for the Brigadier, despite his "military mind", (TV: Frontier in Space) and often found himself telling his assistants to show him due respect. (TV: Doctor Who and the Silurians, The Dæmons)

Despite his occasional rudeness, the Doctor grew very fond of his friends, often taking on the role of a teacher turning them into young scientists, (TV: The Dæmons) though he also enjoyed a professional relationship with his scientific equal, Liz Shaw. (TV: Spearhead from Space, Doctor Who and the Silurians) At first, he was fearful of Jo Grant due to her bumbling nature, (TV: Terror of the Autons) but soon became fond enough of her to feel that meeting her made his exile worthwhile, (TV: Frontier in Space) becoming upset when she decided to leave his company in pursuit of marrying Professor Clifford Jones. (TV: The Green Death)

While the Third Doctor initially only saw the Twelfth Master as an "unimaginative plodder" that only caused trouble, (TV: Terror of the Autons) he eventually came to see him as the "personification of evil." However, he still visited him in prison due to their old friendship. When he and the Master broke out into a sword fight, the Doctor duelled him light-heartedly, being courteous to let the Master retrieve his weapon, and throw banter with him. He even stole a sandwich from a platter in the Master's cell and began eating it while he had his sword pinned on the Master's neck, for no reason other than a playful show of spite. (TV: The Sea Devils) However, the Doctor distrusted him greatly, such as when he met the Tremas Master in the Death Zone, and, despite him carrying the Seal of the High Council as proof, the Doctor refused to believe the Master had been sent to aid him, instead assuming him to be behind the predicament and having stolen his credentials, and held no qualms about leaving him stranded in an attack. (TV: The Five Doctors)

Resentful at them for exiling him, the Doctor thought the Time Lords to be a "mean, despicable, [and] underhanded lot" (TV: Spearhead from Space) who "delighted in deviousness". (TV: The Five Doctors)

He was afraid of the Daleks, (TV: The Mind of Evil) viewing them as "the most evil [and] ruthless life form[s] in the cosmos", (TV: Day of the Daleks) and took "great satisfaction" in destroying them. (TV: Planet of the Daleks) Because they were inherently violent and lacked the intelligence to reason with properly, the Doctor did not show restraint against Ogrons, immediately resorting to fatal action if they were given orders to kill. (TV: Day of the Daleks, Frontier in Space)

Sarah Jane Smith once described the Third Doctor as being like a "favourite teacher". (PROSE: Still Need a Title!)

Charles Lawrence called the Third Doctor "insolent, [and] impertinent", and criticised him for "showing no respect for [his] authority", (TV: Doctor Who and the Silurians) while King Dalios recognised him as a philosopher. (TV: The Time Monster) Florrie Cooper considered the Third Doctor to be "a proper toff". (AUDIO: The Three Companions) When the Eighth Doctor had a tarot card reading, the Third Doctor was identified as "the Emperor". (PROSE: The City of the Dead)

While the Twelfth Master described the Third Doctor as a "bouffanted buffoon", (COMIC: Doorway to Hell) the Tremas Master remembered him as a "worthy foe" with "such cunning [and] such ingenuity" that was "all wasted through [his] stubborn streak of goodness". (GAME: Destiny of the Doctors)

After confronting the Great One on Metebelis III to redeem himself for causing her incursion on Earth after stealing a Metebelis crystal, the Doctor returned to his UNIT lab on Earth, claiming to Sarah Jane that "the TARDIS [had] brought [him] home". Telling a saddened Sarah that facing his fears was more important than "just going on living", he wiped away her tears and tried to comfort her as he succumbed to the radiation poisoning of the crystal. (TV: Planet of the Spiders)

Habits and quirks
The Third Doctor developed a habit of uttering, "good grief", when he was annoyed, (TV: The Ambassadors of Death, The Dæmons, The Curse of Peladon, The Green Death, The Five Doctors) surprised (TV: Day of the Daleks, The Sea Devils, The Three Doctors, Frontier in Space, Invasion of the Dinosaurs) or alarmed. (TV: The Time Monster, The Green Death, Planet of the Spiders) When tampering with machinery, he would find himself having to "reverse the polarity" to achieve his objectives.

When in moments of panicked outrage, he would often ask, "What/Who the blazes…". (TV: Terror of the Autons, Colony in Space, The Mutants, The Time Warrior, The Monster of Peladon) He also used words such as "pompous" and "nitwit" to describe people he thought were idiots.

(TV: Spearhead from Space, Doctor Who and the Silurians, Inferno, Terror of the Autons, Planet of the Daleks)

(TV: Doctor Who and the Silurians, Inferno, Terror of the Autons, Death to the Daleks)

When not in the pockets of his jackets, the Third Doctor would often stand with his hands on his hips, (TV: The Dæmons, Day of the Daleks, The Sea Devils, The Mutants, The Green Death, Death to the Daleks, Planet of the Spiders, The Five Doctors) or keep them in the pockets of his trousers. (TV: Inferno, Day of the Daleks, The Time Warrior, Invasion of the Dinosaurs, Death to the Daleks, The Monster of Peladon, Planet of the Spiders) He typically stood with a single hand in his pocket, while his other hand dithered above his waist or by his side.

He sometimes stood with his hands crossed behind his back, (TV: The Mind of Evil, The Claws of Axos, The Mutants, Frontier in Space) or in front of him. (TV: The Curse of Peladon, Frontier in Space, Planet of the Daleks, The Green Death, The Time Warrior) He would also have his arms folded on occasion. (TV: Day of the Daleks, The Sea Devils, Invasion of the Dinosaurs, Planet of the Spiders)

Fidgety when in thought, the Third Doctor would rarely not be seen scratching at his mouth and chin, (TV: The Dæmons, The Shrink, Dimensions in Time) rubbing his fingers with his thumb (TV: The Ambassadors of Death, Inferno, Terror of the Autons, The Dæmons, The Sea Devils, Frontier in Space, Planet of the Daleks, Invasion of the Dinosaurs, The Monster of Peladon, Planet of the Spiders, The Five Doctors, The Shrink, Dimensions in Time) or singlehandedly rub at his neck.

(COMIC: Assassin from Space)

When he needed to respond to something, he would utter, "I see". When his friends guessed correctly, he would call them the "top of the class". When annoyed, he would say, "for heaven's sake", and was known to indulge in epizeuxes.

Skills
Possessing strength that rivaled a healthy young man (COMIC: The Magician) and a reaction time "ten times faster" than a human's, (TV: The Time Monster) the Third Doctor was a man of action, joining the fray whenever needed with his mastery of Venusian aikido, (TV: Inferno) boxing, (TV: Carnival of Monsters) Saturnian kung-fu, (PROSE: The Devil Goblins from Neptune) Martian karate, (PROSE: Inferno) and Mercurian kung fu. (COMIC: Heralds of Destruction) The Third Doctor's skill at combat was so exceptional that the Sixth Doctor considered him to be the best hand-to-hand combatant of his previous five incarnations. (PROSE: State of Change)

The Doctor was a good marksman, (TV: Day of the Daleks, The Time Warrior) being able to hit a precise spot on a faraway robot from a moving helicopter. (COMIC: Doctor Who and the Robot) He was also a skilled swordsman, (TV: The Sea Devils, The Monster of Peladon) and could score a perfect golf game while blindfolded. (TV: The Sea Devils)

The Doctor was able to break states of hypnosis and mind control caused by others, (TV: Spearhead from Space, Terror of the Autons, The Green Death, The Time Warrior) and could also resist forms of hypnosis which would defeat weaker-minded individuals, (TV: The Claws of Axos, The Green Death, The Time Warrior) such as being able to withstand numerous mind probes. (TV: Frontier in Space) He could also perform standard hypnotism. (TV: The Curse of Peladon, The Green Death)

Having an enjoyment for tinkering with gadgets, (TV: Doctor Who and the Silurians) though unsatisfied with the technology at his disposal during his exile, (TV: Spearhead from Space, The Ambassadors of Death, Terror of the Autons, The Claws of Axos) the Doctor was able to use what he had to quickly construct equipment needed to defeat his adversaries.

(TV: The Time Warrior)

The Third Doctor's knowledge of the TARDIS greatly increased from his previous incarnations, chiefly due to him repeatedly taking it completely apart and reassembling it to try and make it work during his exile. (TV: The Ambassadors of Death, Inferno, The Claws of Axos, Day of the Daleks) Once the Time Lords returned the knowledge of how to operate it, (TV: The Three Doctors) the Doctor was more adept at controlling his destinations than before, denying any mistake on his part if he strayed, and being elevated when he learnt he had been interfered with, rather than his navigation being faulty. (TV: Carnival of Monsters, Death to the Daleks)

According to River Song, he was as an "amazing gourmand", (GAME: The Eternity Clock) and once prepared a roast dinner for Jo, Iris Wildthyme and Tom. (PROSE: Verdigris)

When his body underwent too much strain, or he was exceptionally injured, the Doctor could force himself into a coma to allow himself to heal. (TV: Spearhead from Space, The Dæmons, Planet of the Daleks, The Monster of Peladon)

Appearance
The Third Doctor had a "craggy" face that made him look like a grandfather, (AUDIO: A True Gentleman) with a shock of white hair, a pronounced chin, a pointy nose and blue eyes (TV: Spearhead from Space) that "sparkled with intelligence". (AUDIO: A True Gentleman) By his own account, he had "slim, artistic hands". (PROSE: Independence Day) The Doctor sported a tattoo of a snake coiled into the shape of a question mark on his right forearm, (TV: Spearhead from Space, Doctor Who and the Silurians) which was a mark made by the Time Lords to signify that he was in exile. (PROSE: Christmas on a Rational Planet)

The Doctor disliked his face at first, but quickly thought himself as looking "quite distinctive". (TV: Spearhead from Space)

Jo once described the Doctor as a "whirlwind in a frilly shirt," (AUDIO: The Doll of Death) while Irongron described him as a "long-shanked rascal, with a mighty nose." (TV: The Time Warrior) Cindy Wu commented that he had a "nice face" that looked "sort of old, but young at the same time." Though he appeared older than the Tenth Doctor, Cindy found that she could tell the true difference in their age by looking into their eyes. (COMIC: The Lost Dimension) Arthur Ollis described the Third Doctor as being "tall, [in] fancy get up, [with] white hair." (TV: The Three Doctors)

The Fifth Doctor described his third incarnation as an "aristocrat", (PROSE: Five Card Draw) while the Sixth Doctor called him the "ruffle-shirted toff with the big nose", (PROSE: The Shadow in the Glass) and "a tall chap with white hair and rather flamboyant clothes". (AUDIO: Urgent Calls) The Seventh Doctor described him as "tall [and] white-haired". (PROSE: First Frontier)

When Affinity took on the Third Doctor's appearance, the Twelfth Doctor noted that his third incarnation had "[a] rather impressive height, [with] an impressive bouffant of white hair." The manifestation appeared in a "ruffled shirt, purple velvet smoking jacket, and scarlet-lined cape." (PROSE: Silhouette)

Hair and grooming
Shortly after his regeneration, the Third Doctor possessed a flat, inconspicuous short-cut hairstyle, (TV: Spearhead from Space) that gradually evolved into a voluminous and exuberant bouffant. (TV: Inferno, Terror of the Autons, The Dæmons, Day of the Daleks, The Time Monster, The Three Doctors, The Green Death, The Time Warrior, Planet of the Spiders)

When Ace encountered the Third Doctor in the Seventh Doctor's mind, she noticed that he had "a shock of white hair." (PROSE: Timewyrm: Revelation) River Song believed that the Third Doctor's hair made him look "like a lion", (GAME: The Eternity Clock) while Winstanley mistook it for a wig. (TV: The Dæmons)

Main attires
Following his regeneration, the Doctor kept wearing a TARDIS homing watch on his left wrist and a flat metal chain bracelet on his right. After he stole clothes from Ashbridge Cottage Hospital, his outfit consisted of a white frilled shirt, a navy blue velvet suit, black trousers with suspenders, black dress shoes, a black cravat and Dr. Beavis' black Inverness cape with red innings and his black fedora hat. (TV: Spearhead from Space) The Doctor had chosen these clothes to help him cultivate his chosen persona, but he eventually decided that the Fedora hat had been a mistake. (PROSE: Prisoners of the Sun) He returned them after being recruited by UNIT, since one of his requests for his employment was identical clothing to call his own. (TV: Spearhead from Space) His choice of clothes would change with a variety of colours and designs that were kept in a wardrobe by the TARDIS control console. (TV: Planet of the Daleks)

The Third Doctor wore a variety of smoking jackets and blazers, with colours and designs coming in navy blue with a rolled collar, (TV:  Doctor Who and the Silurians) maroon with a rolled collar, (TV: Terror of the Autons) rust orange with a notched collar, (TV: The Curse of Peladon) olive green with a notched collar, (TV: Carnival of Monsters) plum purple with a notched collar, (TV: Planet of the Daleks) petrol blue with scarlet piping on the notched lapel, (TV: The Green Death) aquamarine with a notched collar, (TV: Invasion of the Dinosaurs) emerald green with a notched collar, (TV: The Monster of Peladon) charcoal with a notched collar, (TV: Planet of the Spiders) and burgundy with a rolled collar.

He wore a series of Inverness capes that could function as "para-cloaks" if needed, (COMIC: The Hungry Planet) which were coloured in red silk-lined black, (TV:  Doctor Who and the Silurians) purple silk-lined black, (TV: Terror of the Autons) red and green tartan, (TV: The Curse of Peladon) blue silk-lined black, (TV: The Three Doctors) burnt orange silk-lined brown, (TV: Carnival of Monsters) grey checked with mid-blue lining, (TV: Invasion of the Dinosaurs) and brown tartan. (TV: The Five Doctors)

On his collars, he wore a black cravat, (TV: Doctor Who and the Silurians) a midnight blue cravat, (TV: The Ambassadors of Death) a white jabot, (TV: Terror of the Autons) a patterned jabot, (TV: The Dæmons) a vermillion cravat, (TV: The Mutants) a black bow tie, (TV: The Three Doctors) a bottle green bow tie, (TV: Planet of the Daleks) a wine red bow tie, (TV: The Green Death) a cyan bow tie, (TV: The Time Warrior) an ivory bow tie (COMIC: The Lost Dimension) or he would go with an unbuttoned collar instead. (TV: Day of the Daleks) Sometimes, he would don a magnifying glass pendant. (TV: The Time Warrior)

He sometimes wore either a grey, zigzagged patterned waistcoat, (TV: The Curse of Peladon) or a 6-buttoned crimson velvet collared vest with a golden fob watch. (TV: The Green Death, Death to the Daleks) He also had a pair of knee-high wellington boots. (TV: Carnival of Monsters)

The Third Doctor was also keen on wearing decorative rings, having a coin mounted on a silvery circlet on his left little finger, (TV: Spearhead from Space) and a plain one on his right little finger at some point. (TV: The Green Death) He also sometimes wore riding gloves while driving Bessie (TV: Doctor Who and the Silurians) or outdoors in general. (TV: The Claws of Axos)

Because of his more frilled and flamboyant fashion, his first incarnation sneeringly called him a "dandy," (TV: The Three Doctors) while his second incarnation labelled him "fancy pants". (TV: The Five Doctors) Upon first seeing him, Morgan thought that the Doctor was wearing "fancy dress". (TV: Colony in Space)

Information from invalid sources
In 1995, Pertwee reprised his role as the Doctor for the fan film Devious, filming a regeneration scene to transition between the film's "Second-and-a-Doctor" and the Third Doctor. Audio from Pertwee's scene was later used for Zagreus, and parts of the film (including the regeneration scene) were included in the form of a trailer of sorts on the DVD release of The War Games. However, this wiki deems Devious to be invalid, partially under the factor of it being fan-made, and additionally for being unreleased in full.

Casting

 * Ron Moody was approached by the producers after his success in Oliver Twist, but he turned down the role. He stated in interviews that turning down the role of the Third Doctor was the worst thing he ever did professionally.

Costume influences

 * The Third Doctor's wardrobe was more colourful and ornate than any of those of his previous incarnations partially because, in real life, the BBC was experimenting with various combinations of colours during Jon Pertwee's tenure in the role to determine which ones would photograph best.
 * The Third Doctor's increasingly-bouffant hairstyle originated from Katy Manning teasing Pertwee about a tiny bald spot on the back of his head, and then recommending he make his hair "bigger" to cover the bald spot when he became self-conscious about it. (DCOM: Planet of the Daleks)

Reprising the role

 * In early 1996, Pertwee reprised the role again for a Vodafone advertisement, in which an unnamed government agent (played by Kyle MacLachlan) travels to Liverpool to prevent the construction of a dangerous time machine. When this device turns out to be an elaborate karaoke machine, the agent leaves – not realising that an actual alien time traveller, the Doctor, is coincidentally working in a garage two doors down. Pertwee died the following May.

Other matters

 * The Third Doctor is unique in having first appeared in the title sequence before appearing in any actual scenes on the show.
 * The tattoo visible on the Doctor's arm during Spearhead from Space was Pertwee's own, left over from his days in the navy. It can be seen more clearly in the 1955 film, A Yank in Ermine, and its promotional images.
 * "Reverse the polarity of the neutron flow" is often thought to be the Third Doctor's most commonly-used quote, when he in fact only says it fully during his tenure in The Sea Devils, and then says it again when guest starring in The Five Doctors. More often than not, he used the simplified saying, "reverse the polarity".
