Third Doctor

The Third Doctor was the third incarnation of the Time Lord known as the Doctor. Throughout the majority of his life, this Doctor was stranded on Earth as part of his exile by the Time Lords, a fact that made him somewhat bitter at times.

This Doctor entered the service of United Nations Intelligence Taskforce, becoming their unpaid scientific advisor, and remained in their service long after his exile was lifted. He stood out from his predecessors in his willingness to engage others physically, and cut a more dashing figure than them, as well.

In his first year with UNIT, he was assisted by Liz Shaw, whom he replaced as UNIT's scientific advisor. She assisted him in his research and experiments. An intelligent scientist in her own right, she left to pursue her own research. She commented that all the Doctor truly needed in an assistant was someone to pass him his test tubes and tell him how brilliant he was.

During his time out in the field as UNIT's advisor, the Doctor was aided by Sergeant Benton and Captain Mike Yates, and even the Brigadier himself. The Doctor hardly got along well with the Brig in the beginning, but they became good friends, with an easy mutual trust developing between them.

The Doctor was given a new assistant, Jo Grant, who was bubblier and less scientifically-inclined than Liz. The Doctor found her a most useful companion in his adventures both during and after his exile. Jo got in trouble easily, and the Doctor became quite protective of her. However, the Doctor lost his assistant when she parted from UNIT to marry Clifford Jones.

In his final year with UNIT, the Doctor was joined by inquisitive journalist Sarah Jane Smith. They went many places in time and space, even visiting Peladon again. He found her inquisitive skill quite useful in their travels, but he often had to save her.

The Third Doctor was forced to regenerate after being exposed to large amounts of radiation during his efforts to stop the Eight Legs of Metebelis III.

Exile


Following the struggle with the War Lords, the Second Doctor was sentenced by the Time Lords to a forced regeneration and exile on Earth. To enforce this ruling, the Doctor's knowledge of TARDIS operation was blocked. (DW: The War Games) Upon his regeneration's finalisation (TVC: The Night Walkers), the Doctor collapsed outside his TARDIS, on 20th century Earth, near a UNIT patrol. He was brought to a hospital in a coma.

At the time of the Doctor's arrival, a swarm of power units for a non-physical alien intelligence known as the Nestene Consciousness was uncovered. Normally disembodied, it had an affinity for plastic and was able to animate humanoid facsimiles known as Autons. The Nestene Consciousness took over a toy factory in London, and planned to replace key government and public figures with Auton duplicates. The Doctor was brought to UNIT HQ, commanded by Brigadier Alistair Gordon Lethbridge-Stewart. The Doctor was uneasy about the Brigadier since their last meeting and was eager to reclaim his TARDIS key to escape the planet, but he realised that not only was his knowledge on how to operate the TARDIS blocked, but the dematerialisation codes had been changed.

With Dr. Elizabeth Shaw helping him, the Doctor created a device to stop the Autons. The Brigadier feared the Nestenes might return and asked for the Doctor's continued assistance. The Doctor agreed to join UNIT as their scientific advisor in exchange for facilities to repair the TARDIS and a car like the sporty antique roadster he had commandeered during the incident. Liz stayed on as his assistant. (DW: Spearhead from Space)

Incidents on Earth
The Doctor and the Brigadier then travelled to the zoo, where they were surprised to discover that the normally-peaceful animals were attaching the visitors. They discovered that a local student name Cedric Matthews had created a "change" potion to enrage the animals, and that he planned to affect his fellow students at Arkwood Private School too. The Doctor was able to create an antidote to cure the students, whilst Matthews was sent to a detention center. (TVC: The Arkwood Experiments)

The Doctor then encountered an three foreign agents, who had stolen an advanced Multi-Mobile to attach the British Nuclear Defence Control Centre. The Doctor was able to stop them by putting Sugar cubes in their patrol tank. (TVC: The Multi-Mobile)

The Doctor then encountered large insects, including caterpillars and ants. He discovered that the insecticide has been badly mixed, and created an antidote to return the insects to their normal size. (TVC: Insect)

Summoned by the Brigadier to an underground research centre on Wenley Moor, the Doctor and Liz Shaw first met the Silurians. The Silurians had gone into hibernation millions of years ago but were revived by power from the research centre. The Doctor strove for peace between the reptiles and humans and even managed to gain the trust of the old Silurian leader. However a rebellious young Silurian seized power and released a deadly virus that threatened to wipe out humanity.

The Doctor found an antidote with Liz' help, 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 were forced to return to their caves when the Doctor overloaded the reactor, threatening to cause a nuclear explosion. The Brigadier, to the Doctor's disgust, had the Silurian base destroyed. (DW: Doctor Who and the Silurians)

The Doctor would later show distrust in the Brigadier, even going out to meet an alien on his own. Multiple UNIT soilders follow him, and stop him from meeting the alien. The alien, meanwhile, had attempted to communicate with local citizens telepathically, which inadvertially had caused their death. The alien was chased up a church, and as it attempted to talk with the soilders telepathically, the Doctor had no choice but to shoot it, killing it. (VD: The Straw that Broke the Camel's Back)

The Doctor and the Brigadeir then encountered "ghosts" in a castle. The Doctor was able to stop them with a machine that caused them to freeze. (CC: Old Soldiers)

Later, the Doctor, Liz, and the Brigadier would go to investigate two reports of rusting metal. The Doctor would discover that it was from a meteorite that crashed near-by, and used an anti-corrosive liquid to stop rusting at he third site. (TVC: The Metal Eaters)

The Doctor learned of ships being given misdirections that lead to it sinking. He believed that the signals are being sent from underground, from a base run by Carpanthans, who he was able to persuade to be peaceful to the humans. (TVC: The Fishmen of Carpantha)

The Doctor was them captured by aliens who wanted to kill him, so that he would not get in the way of their invasion of earth. The Doctor was able to defeat them with the lazer in his cane. (TVC: Assassin from Space)

The Doctor had to infiltrate the base of foreign agents, who had stolen UNIT technology. He used his obedience spray to retrieve it. (TVC: Undercover)

The Doctor was then sent to the Scottish Highlands, where he was to try and identify if a rock one of the scientists there had was indeed from Venus. The Doctor found it to be a fraud, and in retaliation, the scientist, named Logan, sent the Doctor into space. The Doctor was able to steer the ship, however, and threatened to drop it on Logan's ancestral home. Logan admitted he was a fraud, and the Doctor landed the ship. (TVC: Doctor Who and the Rocks from Venus)

The Doctor helped radiation-dependent alien ambassadors who had been kidnapped by the xenophobic retired astronaut, General Carrington. Carrington wanted to discredit the aliens and convince the world to wage war against them. The Doctor and UNIT thwarted his plans and arranged the exchange of ambassadors for astronauts. (DW: The Ambassadors of Death)

Later, the whitch-queen Karolina crossed over from another dimension and invaded Briton. The Brigadier and his men tried to fight her, but all perished. The Doctor and Liz escaped, but eventually were returned to her, where the Doctor challenged her to a duel. He was loosing, when Liz walked up the the queens staff and said that there was no such thing as magic. This disactivates her power, and the Brigadier appeared. He revealed that "Karolina" was actually a metal-patient named Caroline Brown, who's Chrystal staff gave her hypnotic abilities. She was later locked back up in her cell. (ST: The Science of Magic)

One of Liz's last regular work with the Doctor and UNIT occurred when UNIT was providing security at an experimental drilling project to penetrate 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 accidentally transported by the partially-repaired TARDIS console into a parallel universe where the drilling project was at a more advanced stage and worked 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, allowing him to save his own universe at the cost of the director of the operations becoming one of the creatures. (DW: Inferno)

The Time Lords send the Doctor to the future Earth to retrieve a capsule for Liz Shaw. There he finds that Liz has reshapen the world in purely rational lines. When this timelines doctor disliked her plan, he was placed in cryogenic suspension. The Doctor helped the alternate timeline's UNIT stop the group and returned to his normal time. He gave Liz the capsule, and within she found a recording of her dreams in the future, after seeing such, she agrees to put her intelligence to better use. (ST: Prisoners of the Sun)

Later that year, at Christmas, the Doctor and the Brigadier argued over the Doctor's electricity bills. Liz reminded the Brigadier that the doctor was alone with no family on Earth. The Doctor decked a ship orbiting Earth, but after learning it was harmless, he returned to the part to apologize to the Brigadier. He and Liz watched the sun rise from space. (ST: UNIT Christmas Parties: First Christmas)

Liz then went to visit her friend Jean Baisemore, but found her missing, with parts of metal in her house found to have merged. Twelve other people wer found to be missing, and one mysterious suicide was discovered, who's body was slowly turning into blue gold. Out of the man's shoulder, multiple Cybermats appeared. The Doctor and Liz were lead underground, where they met Jean again, who has been turned into a Cyberman. The Doctor was able to create peace with the Cybermen, but soon enough the Brigadier sent multiple men down to deal with them. (CC: The Blue Tooth)

The Doctor then encountered Silurian-Sea Devil hybrids (MA: The Scales of Injustice) and devils from space. (PDA: The Devil Goblins from Neptune)

One day, multiple soilders came in to paint the Doctor's lab. As the Doctor protested this, Liz left, having earned new job opportunities at CERN, without saying goodbye. (BE: Country of the Blind)

Later, the Doctor and the Brigadier travelled to the Caribbean on vacation, when they were attached by a giant squid. They found Fredric Simba, the man controlling the squid, and had him arrested. (TVC: Castaway)

After reading a book, the Doctor discovered he had levitating abilities. Meanwhile, the Brigadier was chasing a spy who had stolen some secret government files. The man climbed up a wall, but ended up hanging off the roof, putting the files in danger. The Doctor was able to arrive and help the man down. (TVC: Levitation)

The Doctor was then asked by Professor Carl Readon to check the emotions on his new robot. The Doctor discovered them to be functioning, but the next day, after the Professor yelled at one of his assistants for bringing his dog to work, the robot went berserk, attaching the city. The Doctor soon realise the robot merely missed the dog, and reunited the two. (TVC: Doctor Who and the Robot)

The Doctor was later called in to investigate the ruins of an inn that had burned down. He discovered it had been done so by Fire people, an ancient race that lived beneath the Earth. The Doctor went to see them, but found most of them to be surprisingly peaceful, except for a small faction associated with Victor, a professor of volcanology. Victor and his Fire People chased the Doctor through the Earth, until they arrived at the Arctic, where the Fire people burned out and Victor collapsed. (TVC: Trial of Fire)

After helping build a rocket, (DWM: ''Prelude: White Darkness) the Doctor obtained a power sorce great enough to make a quick trip in the TARDIS. He blacked out, and woke to find himself at a masked ball during the Napoleonic Wars with Emma Hamilton. There, aliens landed to retrieve Emma's ring, which was actually the species' power soarce, having accidentally been sent back in time. Lord Hamilton had her wife give them the ring, and the Doctor returned to his own time. (ST: Danse Macabre)

The Doctor was asked by millionare John Henderson to drive his time-travelling bulldozer into the future. There, the Doctor finds the primitive, war-based society of 2971. He finds one of Henderson's descendants rules part of the future world, while the the other was ruled by King Trent. The Doctor and the ex-prisoner Cooper help the men see the error of their ways and create a treaty. The Doctor returned home, and began to show the original Henderson the true value of friendship. (TVC: The Kingdom Builders)

Liz had extensive training, but it paled in comparison to the Doctor's own knowledge of the universe and scientific principles. She resigned from UNIT and returned to Cambridge. She reportedly told the Brigadier that all the Doctor really needed was "someone to pass him his test tubes and tell him how brilliant he was." This feeling probably contributed to her decision to return to her own research. (DW: Terror of the Autons)

A renegade Time Lord known as the Master went to Luigi Rossini's circus and stole a dormant Nestene energy unit from a museum. He reactivated it with a radio telescope and took control of a small plastics firm where he produced deadly Auton dolls, chairs and daffodils. He schemed to destroy humanity and silence the Doctor forever with the Nestene. Aided by the Brigadier and his new companion, Jo Grant, the Doctor thwarted the Master's plans. (DW: Terror of the Autons)

Later, the Doctor, the Brigadier and Jo went to meet two astronauts who had returned from Mars. The Doctor discovered that their minds had been overtaken by Minoans, a ruthless alien life form. When the aliens attempted to take over the Doctor's mind, he was able to return the astronauts to normal, and the Minoans retreated. (DWM: Dark Intruders) Afterwards, they encountered robots, the Klatriss (DWM: War in the Abyss) and the Kelads. (DWM: Hunt to the Death)

The Doctor was shocked to discover that one of his closest friends, Giles Winston, had gone missing. The Doctor and Jo tracked him down to an abandoned wartime factory. They eventually discovered that the Master was waiting for them.

The Master revealed that he had discovered a way that both of them could escape their exile, and that he had brought the Doctor here to help Winston perfect the portal into another dimension. As Jo jumped out of the Master's reach, he shot the portal, closing it for good. (DWM: Doorway into Nowhere)

The Doctor, Jo, and Mike Yates were later attached by a giant claw in the mist. They had been driving to a remote island, where multiple people had been reported missing. On the way there, they picked up an elderly hitchhiker named MacFee, who picked up a pot by the island. On arrival, he turned out to be the mist itself. The Doctor woke in a ship, next to a large crab. The Doctor was able to stop it by blowing up it's ship. (DAM: The Claw)

A small flying saucer landed on Druid's Table, a flat rock near John Breen's farm. Bremen reported it to UNIT, and then called his son, a journalist. By the time his son, Ernest Breen, arrived to help him, he had disappeared. His son went to drop the saucer near UNIT, but he too disappeared. Despite warning from the Doctor, the Brigadier also picked it up to bring to the Doctor, but then he too disappeared. The Doctor recognised the technology as that of Triolites from Ur. He built his own device, and taught Jo how to control it. He grabbed the caucer, disappearing upon the ship. He gave Jo the signal, and his mechanism began destroying the ship as the Doctor, the Brigadier, and the two Breens escaped. (DWM: Saucer of Fate)

Strange lights began to appear in the sky, and the diamonds of the world begin to disappear! The Doctor concludes that aliens had hid in the sky, disguised by making their light waves stay invisible. The Doctor was able to make glasses to see them, and a weapo to attach them. (DWM: The Phaser Aliens)

Liz Shaw contacted the Doctor from Cambrige on time distortions, and the pair had an adventure in 2014. (CC: The Sentinels of the New Dawn)

The Doctor, Jo and the Brigadier then encountered the lord Hades, who they were able to stop with the help of The Master and Zues. (PDA: Deadly Reunion)

Later that year, at Christmas, the UNIT party was interrupted by Dr. Fischer, a scientist from Geneva. Upon inspection, the Doctor finds it to be the Master in disguise. The Master admits that he too had been permanently exiled to Earth, and only wanted company for Christmas. The Doctor and the Master shared a drink, and the Master left. The Doctor discovered multiple explosions and audio bugs around the UNIT base, but Jo said that the Master knew he would find them, and was sincere about why he came. (ST: UNIT Christmas Parties: Christmas Truce)

The Doctor and Jo visited Stangmoor Prison 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 had lost control of it. The machine was destroyed, but the Master escaped again. (DW: The Mind of Evil)

The Doctor later encountered an alternate universe playing in reverse, and jumped into that Univurse in order to stop Doreen Killebrew. (CC: The Doll of Death)

The Doctor discovered that he was able to make one trip in the TARDIS, and travelled with Jo to Estringokl, where the inhabitants calibrate Christmas Eve every year. The Doctor was shocked, however, to discover that the entire planet was lifeless, and covered in ice. Upon closer inspection, he discovered that the planet had one tree on it. The Doctor recalled a forgotten memory, that the inhabitants had planet this tree to signify their traditions brought back from Earth, but as it became sick, even to the point of freezing the planet, even the robots were catering to it. On one visit he had promised a robot that he would continue their work, but this memory had been removed by the Time Lords. The Doctor thus used the TARDIS to finish his decorating of the tree, travelling through time eleven times. It was on the final occasion that the pioneers woke from a deep sleep, and they surrounded the tree for a new Christmas celebration. (ST: The Thousand Years of Christmas)

The Doctor was reunited wi Liz Shaw once more, when she invited him to come as a guest to a lecture on psi powers. They learned that Professor Brockhurst, a teacher at Cambrige who was to attent the lecture, had died, chocking on food at a restraint. Suddenly, the plane's engine went out, however, they were able to stay in the air thanks to a woman with psychic abilities, who died once they landed. Liz recognised her as one of Hardin's pupils, the rival to Brockhurst, and they go to talk to him. Hardin refused to talk to them, however. Theorising that Hardin caused Brockhurst's death, and that he had been doing invalid surgery on his students, the Doctor called the Brigadier and organises a mass protest against Hardin. Hardin revealed that he had done surgery on his pupils to unleash thir phycic abilities, but had also done surgery on himself. He began to sufficate the Doctor's lungs with his powers, but the Brigadier shot him. (DWM: Change of Mind)

After the Master came to the Earth, the Time Lords allowed the Doctor limited use of his TARDIS. However it always returned him to 20th century Earth when his missions were completed, turning him into "some sort of a galactic yo-yo." (DW: The Claws of Axos)

When the Time Lords discovered the Master had stolen their secret file on the Doomsday Weapon, they sent the Doctor to retrieve it for them. Jo left the planet for the first time. They arrived on the planet Uxarieus and convinced the last native Uxariean to destroy the Weapon. (DW: Colony in Space)

The Doctor discovered that in Devil's End an old evil was asleep and tried to stop its awakening. The Master, posing as a rural vicar, summoned the last of the Dæmon's kind, Azal. Azal decided to give his power to the Master, and fired energy at the Doctor to kill him. 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 taken into custody. (DW: The Dæmons)

In an alternate 22nd century, a group of freedom fighters tried to thwart a Dalek invasion by coming back in time to the 20th century to assassinate a delegate, Sir Reginald Styles, at the second World Peace Conference in Auderly House. It was thought the delegate had caused an explosion at the conference, starting World War III, which had left humanity vulnerable to the Daleks.

After following the guerillas back to the 22nd century, the Doctor realised that the explosion was caused by one of the fighters, Shura, in a misguided attempt to fulfil his mission, when he had actually been responsible for starting the escalation. After briefly travelling to the 22nd century, the Doctor returned to his time period to ensure the evacuation the delegates. Daleks and Ogrons arrived in pursuit of the Doctor, but were destroyed when Shura detonated his bomb. (DW: Day of the Daleks)

Thinking he had fixed the TARDIS, the Doctor and Jo took it on a test flight but unexpectedly arrived on the planet Peladon. They entered the citadel of the soon-to-be-crowned King 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.

In fact a great conspiracy was occurring between a Federation delegate and the High Priest of Peladon. The Doctor and Jo revealed the conspiracy to the King. The traitors were condemned and relations between the Federation and the Peladon Kingdom were improved. (DW: The Curse of Peladon)

The Doctor and Jo visited the Master, now held in captivity on Fortress Island prison. (DW: The Dæmons) He claimed to have reformed but refused to reveal the location of his TARDIS. As they left, the governor, Colonel Trenchard, told them ships had been disappearing. The Doctor investigated. Jo and he were attacked by a Sea Devil while examining a fort.

The Doctor learned that the Master, assisted by a misguided Trenchard, was stealing electrical equipment from the naval base to build a machine to control the Sea Devils. The Master hoped to use the reptiles to conquer the world, and used the machine to summon some of them. The Doctor entered the Sea Devils' base and tried to encourage peaceful negotiation. Matters were left unresolved, however, when the base was destroyed with depth charges. The Sea Devils were defeated and the Master escaped his imprisonment. (DW: The Sea Devils)

The Doctor was summoned by the Time Lords 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, the human population was 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. (DW: The Mutants)

The Doctor discovered that the Master, in the guise of Professor Thascalos, had constructed a device known as TOMTIT - Transmission Of Matter Through Interstitial Time. This device let him summon the Chronovore Kronos. It proved uncontrollable. The Doctor, Jo and the Master travelled to ancient Atlantis in search of a crystal to control Kronos. The Atlantians summoned Kronos with the crystal, resulting in the city's destruction. Kronos was set free and the Doctor and the Master escaped the destruction. (DW: The Time Monster)

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 first and second incarnations of the Doctor to help the third. The first incarnation was trapped in a time eddy and, unable to fully materialise, could only communicate via the TARDIS scanner. The Second and Third 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 and he returned to the TARDIS with Jo for more adventures in time and space. (DW: The Three Doctors)

Freedom
The Doctor continued to assist UNIT, though his presence on Earth was now more intermittent.

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 home and destroyed the machine, allowing him to return to normal size. He was nearly stopped in his attempts by a corrupt member of the Inter Minor government as they were paranoid about cleanliness. (DW: Carnival of Monsters)

Upon arriving on an Earth freighter the Doctor and Jo were caught up in the escalating tension between planets Earth and Draconia. They soon discovered that the Master was secretly working to provoke the two sides into all-out war under the orders of the Daleks. The Doctor, barely conscious, asked Jo to help him into the TARDIS. He sent a message to the Time Lords, asking them to pilot his TARDIS and follow the Daleks to their new base. (DW: Frontier in Space)

After he slipped into a coma, Jo explored the planet and met a guerrilla group of Thals. After the Doctor regained consciousness, they tried to stop the Daleks from gaining the invisibility of the native humanoid species. They discovered a base with more than ten thousand Daleks hibernating and buried the Daleks deep in the Earth. (DW: Planet of the Daleks)

After several attempts to get to Metebelis III the Doctor landed his TARDIS there. He was attacked by violent beings. While on the planet he took a certain blue crystal. Returning to Earth he joined the Brigadier and Jo at Llanfairfach, where UNIT was investigating a miner who had been found, turned green, in an abandoned coal pit. Global Chemicals was responsible for the pollution, having been directed by the computer BOSS. BOSS used mind control on key company staff and planned on controlling the world based on his initial programming. The Doctor broke BOSS's control using the blue crystal. Once freed, company boss Stevens destroyed BOSS before it could link with computers over the world. Jo and Cliff Jones, a scientist working at Wholeweal, announced they were getting engaged and planned to travel the Amazon looking for a rare fungus. The Doctor offered his blessing and gave Jo the blue crystal he had retrieved from Metebelis III as a wedding present. He then discreetly left to return to UNIT HQ. (DW: The Green Death)

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

The missing scientists had been kidnapped by a Sontaran, Linx, and taken to medieval England, where they were working under hypnosis to repair his crashed spaceship. Following Linx' death and the destruction of his weapons, the Doctor and Sarah began travelling together. (DW: The Time Warrior)

The Doctor, Sarah, Jeremy Fitzoliver, and the Brigadier then went to Space World, a new amusement park, to investigate a death that had happened near by. They discovered it to be run by multiple Naglons from the planet Parakon 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 in order to retrieve them, but discover multiple games accruing, which end in death. They eventually put a stop to them and return to earth. (BBCR: The Paradise of Death)

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 by a time machine in a plan to revert London to a pre-technological level. The masterminds behind the scheme, Whitaker and Grover, were accidently transported to pre-historic Earth. (DW: Invasion of the Dinosaurs)

Later, the Doctor, Sarah, Jeremy, and the Brigadier travelled to San Stefano Minore (but not all at once) and encountered ghosts crossing from Null-Space to Earth. (BBCR: The Ghosts of N-Space)

The TARDIS crashed on the planet Exxilon. The Doctor encountered Marine Space Corps members seeking Parrinium, a cure to a space-plague. 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 functioning on the planet. The Doctor sought to disrupt its functions and remove the power-disrupting facility. Concurrently 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. The Doctor sadly commented that the universe was now down to six hundred ninety-nine wonders. (DW: Death to the Daleks)

The Doctor returned to Peladon fifty years after his last visit. Queen Thalira, daughter of the late King Peladon, sat on the throne. A labour dispute between Pel nobility and miners worsened when apparitions of their deity, Aggedor, attacked and killed several miners. The Galactic Federation desperately needed Trisilicate for its war against Galaxy 5, and sent in brutal Ice Warriors to ensure production. The Doctor brought the miners and ruling class together and they fought the Ice Warriors and rebuilt Peladon. (DW: The Monster of Peladon)

Sarah Jane then travelled to Gatewood, Sussix for a horse race, unaccompanied by the Doctor, who was taking a metabolism test via the Brigadier's advice. She encountered Daleks, who she was able to stop with help from the U.S. Calvary. (AG: Glorious Gatewood)

Death
Mysterious goings-on at a meditation retreat run by Tibetan monks were linked to the blue planet Metebelis III and a colony of monstrous spiders. To defeat them, the Doctor sacrificed his life, exposing himself to lethal levels of radiation to destroy the web of the Spiders' leader, the Great One. With the help of his old mentor, K'anpo Rimpoche, he regenerated into his next incarnation, to the surprise of Sarah Jane and the annoyance of the Brigadier. (DW: Planet of the Spiders)


 * For a list of third Doctor stories in the order in which he experienced them, see Third Doctor - Timeline.

Legacy
The fourth incarnation seemed to dislike his predecessor. He commented that his new nose was a definite improvement only hours after his regeneration. (DW: Robot) When on Karn, the fourth incarnation mentioned that he preferred his then-current form to "what he had last time". (DW: The Brain of Morbius)

The Third Doctor's time with UNIT had a lasting effect. Even though his following incarnations pretty much severed all ties with UNIT, the ninth and tenth incarnations worked with them a few times. None of the Doctor's later incarnations resigned the position. The Doctor was well known within UNIT even up to the late 2000s with its members wanting to meet him. Captain Erisa Magambo and Professor Malcolm Taylor were both excited to hear from him; Magambo saluted him, though it annoyed the Doctor. The two described the Doctor as the man everyone in UNIT wanted to meet but feared the day they would; they knew that that day would bring chaos. (DW: Planet of the Dead)

After his tenth regeneration, the Doctor checked his nose and, disappointed how it turned out, commented that he had had worse, referring to his third incarnation's nose. (DW: The End of Time)

Unrecorded adventures

 * Though sidetracked to the planet Nooma, (MA: Speed of Flight) the Third Doctor, Jo and Mike Yates visited the planet Karfel and encountered the Borad and Katz's father there. (DW: Timelash)
 * The Third Doctor attended the funeral of Alistair Gordon Lethbridge-Stewart. (ST: The Gift)

Personality
The third incarnation often had problems with the Brigadier's tendency to think of situations in military terms, and with petty officials generally. Despite his conflict with the Master, he visited him in prison. Jo noticed that he worried about him; he told her that he was an old friend. (DW: The Sea Devils) He attempted to achieve peace between humanity and the Silurians; he again tried to come to an agreement with the Sea Devils, killing them when he saw no other hope. (DW: Doctor Who and the Silurians, The Sea Devils) While on a diplomatic mission, he fired upon Ogrons who boarded with the intention of taking him prisoner. (DW: Frontier in Space)

The third incarnation was a man of action, aggressively joining the fray whenever he could, unlike the first two incarnations who generally insinuated themselves into events discreetly. He was unafraid to pitch in with his physical skills, often bringing his mastery of Venusian aikido into play when the situation called for it. This knowledge of unarmed combat was given to this regeneration without any training. (EDA: Placebo Effect)

Much like his predecessors, his keen mind was still his primary asset, and this was an incarnation who particularly loved to create and play with gadgets of all sorts. This passion displayed itself in terms of the third incarnation's scientific bent and in his love of vehicles, such as his yellow roadster, Bessie, and his car which he specially built. Sometime, his inventions did backfire on him, but he found ways to repair and improve them.

Staunchly moral, the Doctor was every bit the gentleman, a hero of the Victorian mould. (ST: A True Gentleman)

The Doctor had a noticeably antagonistic relationship with his second incarnation due to their vastly different personalities. Their relationship was so rocky that they were incapable of working together without the presence of the first incarnation. (DW: The Three Doctors, DW: The Five Doctors) In contrast, the fourth incarnation, although he never met himself in his previous incarnation, occasionally spoke rather fondly of that form.

His knowledge of the TARDIS greatly increased in this incarnation (chiefly due to taking it completely apart and reassembling it to try to to make it work). Once the Time Lords returned the knowledge of how to operate it, (DW: The Three Doctors) the Doctor was more adept at controlling his destinations than his previous incarnations, who often lacked any sort of control at all. (DW: An Unearthly Child) He denied any mistake on his part if he strayed, but would eventually find he had been off by outside means, not to blame on the TARDIS navigation. (DW: Carnival of Monsters)

He was usually optimistic. He once declared a belief that life would always continue in some form. (DW: The Mutants)

Habits and quirks
The third incarnation had a passion for gadgets, and loved his vintage car, Bessie, and later, his specially designed futuristic car, almost as much as he loved his TARDIS. (DW: Doctor Who and the Silurians, Invasion of the Dinosaurs)

He occasionally performed magic tricks. The third incarnation was at times very tetchy and argumentative, an attitude that he demonstrated repeatedly with bureaucrats and other authority figures. Being a man of action, he used a wide variety of martial arts including Venusian aikido. He particularly enjoyed wine. (DW: Day of the Daleks) He also had a sort of catchphrase, "Perhaps if we reverse the polarity of the neuron flow..."

Also, it was a little known fact that the third incarnation had a particular preference for limes over lemons in his drinks.

Appearance
Being a man in the appearance of his fifties, the Third Doctor had white curly hair and a big pointy nose. He often smiled when amused, but hardly frowned.

He was known for his ornate fashion sense, most famously his frilled shirt, velvet smoking jackets, and inverness cape outfit. He also wore his frilled shirt with a bow tie or cravat, like the Eighth Doctor. Because of this, his first and second incarnations called him a dandy.

His was the first incarnation to steal clothes from a hospital, followed by his eighth and eleventh incarnations. (DW: Doctor Who, The Eleventh Hour)

Mysteries and discrepancies

 * The newly regenerated Doctor sported a tattoo on one arm. (DW: Spearhead from Space) This was the mark made by the Time Lords to signify the Doctor was an exile. (NA: Christmas on a Rational Planet)
 * The Doctor described himself as thousands of years old, (DW: Doctor Who and the Silurians) which seems inconsistent with figures of his age given in later incarnations. He repeated that age later to Jo Grant. Previous incarnations of the Doctor gave his age to "some hundred years".
 * See separate article.

Behind the scenes

 * "Reverse the polarity of the neutron flow" is thought to be this incarnation's most commonly-used quote, but in fact he only says it fully, on television, in The Sea Devils and The Five Doctors. There are several other occasions, as in The Dæmons, where he mentions simply "reversing the polarity".
 * Katy Manning has accepted responsibility for the third Doctor's increasingly-bouffant hairstyle. She claims that she teased Pertwee about a tiny bald spot on the back of his head until he became self-conscious about it. When she suggested he just put rollers in to make his hair "bigger" — and thereby cover the bald spot — he seized on the idea with alacrity. (DCOM: Planet of the Daleks)
 * The tattoo this incarnation sports is left over from Pertwee's days in the military.

Casting

 * Ron Moody was approached by the producers after his success in "Oliver" but he turned down the role. He has stated in interviews that turning down the role of the Third Doctor was the worst thing he ever did professionally; every time he hears the familiar Doctor Who theme tune he kicks himself.
