Third Doctor

The Third Doctor was exiled by the Time Lords on Earth for a significant period of his life. The technological limits of the time period, and the constraints of his exile, often made him frustrated and bitter. However, he retained his endearing compassion toward his human companions.

This Doctor worked for UNIT as their unpaid scientific advisor, and remained in their service after his exile was ended. Unlike his earlier incarnations, he was quite willing to engage others physically, and cut a more dashing figure.

His foremost enemy was a fellow Time Lord,. Although appalled by the disregard for life inherent in the Master's schemes, the Doctor treated their relationship as somewhat of a friendly rivalry, even enjoying their battle of wits. The Master reflected an equally casual attitude back at him. He also held out hope that he could rehabilitate the Master, whom he had once considered a friend. Though the Master sometimes teamed up with the Doctor to deal with foes who threatened them, he always bent to dark and malicious desires, which kept their mutual antagonism alive.

In the field, the Doctor was aided by Sergeant John Benton, Captain Mike Yates and Brigadier Alistair Gordon Lethbridge-Stewart. The Doctor often took exception to the Brigadier's military approach, just as the Brigadier was frequently irritated by the Doctor's air of superiority and seeming disregard for authority. Despite this, the two men ultimately developed an easy mutual trust and strong friendship.

He was initially assisted in the laboratory by Dr. Elizabeth Shaw. A capable scientist in her own right, she eventualy left to pursue her own work, and the Doctor was given a new assistant, Jo Grant. She was bubblier and had less scientific training, but the Doctor found her a most useful companion in his adventures during and after his exile. They developed a great fondness for each other. Jo left UNIT to marry scientist Clifford Jones.

Shortly thereafter, the Doctor was joined by inquisitive newswoman Sarah Jane Smith. Her journalistic skills and curiosity proved both useful and occasionally hazardous in their travels together.

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

Post-regeneration
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. (TV: The War Games) When the regeneration was completed, (COMIC: The Night Walkers) the 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 the hospital, 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 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. Elisabeth Shaw, the Doctor created a device to stop the Autons. The Brigadier feared the Nestenes would 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. 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. (TV: Spearhead from Space)

UNIT career begins
The Doctor and the Brigadier went to a zoo where the usually placid animals attacked visitors. A ten year old student named Cedric Mathews had created a "change" potion to enrage the animals. He later dosed his fellow students at Arkwood Private School as well. However, the Doctor created an antidote to cure the students, and Mathews was sent to a detention center. (COMIC: The Arkwood Experiments)

The Doctor and the Brigadier next investigated the disappearance of two RAF jets and recruited RAF Captain Mike Yates to help them. After the investigation was complete, Mike joined UNIT. (AUDIO: Vengeance of the Stones)

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)

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. The Brigadier, to the Doctor's disgust, had the Silurian base destroyed with explosives. (TV: Doctor Who and the Silurians)

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 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 transported along with him into the parallel universe, and he was thus powerless to help her. (PROSE: Still Lives)

Later, the Doctor investigated reports of rusting metal, finding it was from a meteorite that had crashed nearby, (COMIC: The Metal Eaters) 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.

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)

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, 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)

Now 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.

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.

(COMIC: The Forgotten)

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. After following the guerillas 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. 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. (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.

Missions for the Time Lords
Thinking he had fixed the TARDIS, the Doctor and Jo took it on a test flight, but due to the Time Lords's 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 worshiped 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 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) Afterwards, the Doctor and Jo encountered what they believed to be ghosts, but they were actually Psion Orbs, items made to project emotion. (PROSE: Spoilsport)

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 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 matters were left unresolved when the base was destroyed with depth charges. With the Sea Devils destroyed, the Doctor was prepared to return the Master to prison, but was unable to do so as the Master once again made his escape. (TV: The Sea Devils)

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 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, thought the Master's true goal was to summon the Chronovore Kronos and use its incredible might for conquest.

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)

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.

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.

Jo and the Doctor then went to a desert planet, where two sisters, Sophia and Alice, who 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 yoyo, an umbrella, and a bag of sweets. Alice was correct, and was crowned queen. (PROSE: Once upon a Time Machine)

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 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 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 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 predident. He also had to reason with the unyielding General John Williams, who joined the expedition 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 a 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, fire 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, his shot had grazed the Doctor's forehead and badly wounded him. The Doctor, barely conscious, asked Jo to 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 lie down and 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 the Daleks 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 a second time, the captive Spiridons, and removing the danger the ten thousand-strong Dalek army posed to other neighbouring races in the galaxy. (TV: Planet of the Daleks) Soon after leaving Spiridon, the Doctor and Jo Grant met with Iris Wildthyme, where they visited Gertrude Stein, and encountered Pablo Picasso. (PROSE: The Scarlet Empress)

The Doctor then travelled to Catastrophea, where he stopped Rekar from beating one of the natives.

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. (PROSE: Catastrophea)

Once freed, company boss Stevens destroyed BOSS before it could link with computers over the world.

Jo and Clifford Jones, a scientist working at Wholeweal, had developed a quick romance in the few days since they had met, and Cliff asked for her hand in marriage, with Jo accepting his proposal.

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, whom 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)

The Minister of Defence ordered the Doctor to investigate an incident in Puddlesfield, where the crew of a new BBC show had turned into plastic.

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 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. (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
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)

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 duo were met by the primitive natives with aggression. The Doctor encountered Marine Space Corps members seeking Parrinium, a cure for 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 working. The Doctor sought to disrupt its functions and remove the power-disrupting facility. 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. (TV: Death to the Daleks)

Attempting once more 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)

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 were called back to Earth by Liz, who herself had been summoned back to UNIT. The Brigadier was acting strangely, and the Doctor deduced that the Brigadier had been possessed by a Remoraxian, a species that wanted to flood the world to allow them to colonise. The Doctor 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 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 storms. Liz, Sarah and the Brigadier were then abducted by Adam Mitchell. (COMIC: Prisoners of Time)

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)

Sarah then began searching through secret files at the Ministry of Defence headquarters, and discovered a Doctor John Smith had died in an explosion. She was alarmed when they eventually travelled to the place and time of the explosion, believing that the Doctor was going to die. The explosion happened before they arrived, and after she told him her fears, he reminded her that "John Smith" was a common name. (PROSE: Numb)

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. With the cooperation of Gebek, leader of the miners, and Thalira's forces, Eckersley and the Ice Warriors were wiped out.

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)

A large cloud of deadly gas created from the destruction of a planet nearly destroyed Earth, but the Doctor was able to discern that it was not natural, and was, in fact, an attempt by the Zirconians to invade Earth. He was able to use the satellites of Earth to set off an explosion to destroy them. (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?)

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)

The Doctor and Sarah then travelled to 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)

The Doctor and Sarah then travelled to the planet Hezrah, where the people worshiped 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)

Time alone
The Doctor went to help his first incarnation escape knights, (PROSE: Five Card Draw) and then attended the funeral of Alistair Gordon Lethbridge-Stewart with his other incarnations. (PROSE: The Gift, Shroud of Sorrow)

The Doctor then helped many colonisers in the far future find a new planet. (COMIC: The Wanderers)

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 had left the company of 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, and drove off. After Bessie was attacked by Cybermen, the Doctor and Sarah encountered a Raston Warrior Robot, which killed the Cybermen, giving the Doctor and Sarah time to escape.

Using stolen climbing utensils from the Raston Warrior, 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 Borusa, who had brought the Doctors there to help him retrieve immortality from Rassilon. When Borusa spoke to Rassilon and took his offer of immortality, he was turned to stone and moved into the tomb. (TV: The Five Doctors)

Final exploits
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)

Facing fears
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 Metebilis 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 posthaste. However, Clegg looked into it, causing his psychic abilities to increase and show him a frightful image of extraterrestrial spiders, which gave him have 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 exposing 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 Metebilis III, horrendously irradiated. (TV: Planet of the Spiders)

A slow demise
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
When the TARDIS finally deposited the dying Doctor back on Earth, he promptly collapsed in his UNIT lab next to Sarah Jane and Lethbridge-Stewart. Looking at Sarah Jane, he tried comforting her, telling her that "while there's life, there's...", 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 started breathing again and regenerated into his next incarnation. (TV: Planet of the Spiders)

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

When trapped in a dimensionally-unstable pocket universe controlled by Iam and the Rani, 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, essentially letting the Third Doctor's persona control his body when he was required to fight. (PROSE: State of Change)

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. (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, due to being shaken 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 his past self 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 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. (COMIC: Dead Man's Hand)

Undated adventures

Alternative timelines
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 converting the Doctor and restoring his ability to travel in time. (PROSE: The Quantum Archangel)

In an alternate timeline created by the Monk, the Doctor was killed during his confrontation with the Silurians- the Monk using his captured Chronovore, Artemis, to prevent the Doctor regenerating when he was attacked- resulting in humanity being decimated as the Silurians attempted to return Earth to its original state. (PROSE: Blood Heat)

In a parallel Earth, a human version of the Doctor existed. He looked like the Doctor's third incarnation, and his companion was Sarah-Jane. (COMIC: Who's Who?)

After his trip to Queiscia, the Doctor discovered a new and mysterious door within the TARDIS, which led to a cell holding one of his future incarnations, who was soaking in his own blood. 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. Shocked by this scene, the Doctor returned to the console room, where Sarah Jane stood, shocked, as she saw the walls bleed. The TARDIS then landed on the planet Dust, where I.M. Foreman had been performing, as the Faction Paradox's ships approached. (PROSE: Interference - Book One) Learning of Foreman's true origins as a Gallifreyian priest travelling with his future selves, the Doctor was able to resolve the paradox of Foreman's original encounter with his future selves before appealing to Foreman's final incarnation to infuse himself with the ecosystem for Dust, transforming the dead world into a lush green one. Satisfied, he headed back to the TARDIS, but he was shot by Magdalena, convinced that this was the only way to protect her world from future invaders, and began to regenerate. (PROSE: Interference - Book Two)

During this incident, he was infected by the Paradox biodata virus (intended for Foreman's final incarnation) while his immune system was occupied with his regeneration. The virus would corrupt him into a member of the Faction, slowly, over the span of his next few incarnations, until completing its work by the time the Doctor was in his eighth incarnation. However, the TARDIS was able to take the infection and fragments of the true timeline into itself, preserving the Third Doctor's essence as a kind of "ghost". With the TARDIS holding on to these fragments even after its near-destruction on Avalon (PROSE: The Shadows of Avalon) and its later corruption into the Edifice as it rebuilt itself, the Eighth Doctor was able to restore the regular timeline and stop the Third Doctor from dying on Dust by destroying Gallifrey, draining the TARDIS of power and forcing the universe to choose which timeline would be real. (PROSE: The Ancestor Cell)

Travelling through the caves of the Death Zone to save Borusa from the Dark Tower, the War Doctor and Cinder found various cave paintings the Doctor speculated were depictions of himself throughout his life, some of which he didn't 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
Due to his exile on Earth, the Third Doctor was often frustrated about his mistreatment and became disrespectful from time-to-time, often getting into bickers with the Brigadier, due to not agreeing with his military methods, but would always apologise for his harsh words. (TV: Inferno) At times, the Doctor could become argumentative and needed to be defused in order to establish fluid communication with his associates, but could be quite humble and sociable when cheerful. (TV: Spearhead from Space)

He spent a lot of his time trying to escape his exile; deceiving Liz Shaw to steal the TARDIS key from the Brigadier, (TV: Spearhead from Space) taking the Console out of the TARDIS and repairing certain parts of its complicated circuitry, (TV: Inferno, Day of the Daleks) or tricking  into repairing his TARDIS while combating Axos. (TV: 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)

Authoritative, yet rebellious, the Doctor was quick to demand action just as much as he felt compelled to take action himself. If unsatisfied with someone's handling of a situation, he would step in forcefully and take charge, especially if they seemed aggressive and undiplomatic.

The third incarnation often held a strong disgust toward people who were any combination of stubborn, selfishly goal-driven, or close-minded. These types of people would anger him further if they refused to listen to him, ignored his protests, or went to absurd lengths just to dodge the risk of being proven wrong. (TV: The Claws of Axos) He was particularly enraged by Eric Stahlman and his parallel universe counterpart, the latter of which destroyed the Earth because of his extreme obduration, while the former came dangerously close to doing the same. (TV: Inferno) He showed a similar anger at General Williams for being utterly convinced he was a Draconian spy without proof. (TV: Frontier in Space)

The Third Doctor always favoured peace and diplomacy above violence and aggression. However, his peacemaking methods clashed with stalwart military-minded individuals, who chose rules over morality. Figures such as the Brigadier were often a thorn in the Doctor's side, especially if they had power and numbers on their side. When he was at odds with a greater majority of imprudent people or a particularly aggressive influential, the Doctor would find his diplomacy usurped. (TV: Doctor Who and the Silurians)

The Doctor would grow increasingly loud and frank with someone being obstinate when he was under the clock to stop something disastrous from happening. If diplomacy outright failed, he did not show further outrage, knowing he had been defeated. Instead, the Doctor reacted in a subdued manner even more unsettling than when he was in protest. Ashamed with the utmost level of disappointment and disgust, he gave a scathing and virulent dressing down to the foolhardy individuals that destroyed a bid for peace and order.

His constant encounters and subsequent headbutting with figures of authority often seeded much violence that could have been avoided had he been allowed to maintain a delicate touch during tense situations. He attempted to achieve peace between humanity and the Silurians, but a younger Silurian with fight and bigotry in him resisted peace, seeding the way for the Brigadier to wipe their colony out. The act of massacre that the Brigadier allowed angered the Doctor, (TV: Doctor Who and the Silurians) and had repercussions when he tried to come to an agreement with the Sea Devils. The Master used the deaths of the Silurians as leverage against humanity, making the Sea Devils vengeful and unreasonable. The Doctor then lost any chance of making peace, killing them when he saw no other hope. (TV: The Sea Devils)

Because the species lacked the intelligence to reason with properly and were inherently violent, the Doctor did not show restraint against Ogrons, immediately resorting to murder if they were given orders to kill. (TV: Day of the Daleks) While on a diplomatic mission, he defended himself against them again with a Draconian prince. Both he and the prince fired upon Ogrons who boarded with the intention of taking them prisoner, because they could not afford to get captured. (TV: Frontier in Space)

Despite his conflict with, the Doctor visited him in prison. When Jo noticed that the Doctor worried about him, he told her that the Master was an old friend. When he and the Master broke out into a sword fight, the Doctor dueled him lightheartedly, being courteous to let the Master retrieve his weapon, and throw banter with his enemy. He even stole a sandwich from a platter in the Master's cell and began eating 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) He even held a thinly veiled, but grudging admiration for his nemesis.

Despite being a self-proclaimed pacifist, the third incarnation was a man of action, aggressively joining the fray whenever needed. However, much like his discreet predecessors, the Third Doctor's keen mind was still his primary asset, with him often exploiting or creating gadgets to assist him in achieving his goals. (TV: Inferno, The Mutants, The Time Monster) He was also an enthusiast when it came to modes of transport, be it cars, (TV: Spearhead from Space) helicopters, motorcycles, (TV: The Dæmons) hovercrafts, (TV: The Sea Devils) or the Whomobile. (TV: Invasion of the Dinosaurs)

Staunchly moral, the Doctor was every bit the gentleman, a hero of the Victorian mould. (AUDIO: A True Gentleman) This was shown when he felt guilt over tricking Omega. (TV: The Three Doctors) An eternal optimist, the Doctor often comforted people when all hope seemed lost to them, (TV: The Time Monster, Planet of the Daleks) even in his dying breath. (TV: Planet of the Spiders) He once declared a belief that life would always continue in some form. (TV: The Mutants)

While very little managed to scare him, the Doctor had a fear of spiders, (TV: Planet of the Spiders) and, after seeing a parallel Earth destroyed in volcanic ash, (TV: Inferno) he feared his own Earth going up in similar fire and destruction. (TV: The Mind of Evil)

Despite his occasional rudeness, the Doctor grew very fond of his friends and assistants, displaying loyalty to the Brigadier, and was very protective of his assistants. His relationship with his companions was very formal, at times he took on the role of a teacher instructing them about the universe. (TV: The Dæmons) At first, he was fearful of Jo due to her bumbling nature, (TV: Terror of the Autons) but quickly became fond of her, (PROSE: The Spear of Destiny) becoming upset when Jo decided to leave his company in pursuit of marrying Professor Clifford Jones. (TV: The Green Death)

The Third Doctor had a noticeably antagonistic relationship with his previous incarnation, their personalities so different that they seemed incapable of working together 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 which 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 incarnation's behavior as "arrogant" and "overbearing", although he stated 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)

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 by quoting Terence's Heauton Timorumenos, but died before he could finish his dying words. (TV: Planet of the Spiders)

Habits and quirks
The Third Doctor developed a habit of using words such as "pompous" and "nitwit" to describe people he thought were idiots. (TV: Inferno) When annoyed or alarmed, he would usually utter, "good grief", (TV: The Dæmons, The Curse of Peladon, The Time Monster, Invasion of the Dinosaurs) and would also say, "Now you listen to me", when trying to gain authority. (TV: Planet of the Daleks, Planet of the Spiders)

The Doctor also made a habit of saying, "Yes, well..." to start his sentences, (TV: Inferno, The Time Warrior, The Monster of Peladon) answering "Yes, of course", (TV: Day of the Daleks, The Three Doctors) and singing when tinkering on things. (TV: Inferno, Terror of the Autons)

The Third Doctor would often stand with his hands on his hips, (TV: Day of the Daleks) or in his jackets' pockets. (TV: Inferno, The Dæmons, The Time Monster, The Three Doctors, Carnival of Monsters, The Time Warrior, The Monster of Peladon) When thinking, he would scratch his chin, (TV: Inferno, The Time Monster) or rub his fingers with his thumb. (TV: Inferno, The Monster of Peladon)

The third incarnation had a passion for gadgets, and loved his vintage car, Bessie, and later, his specially designed futuristic hovercar, almost as much as he loved his TARDIS, even preventing the Brigadier from shooting at Lupton, for fear that he would hit Bessie. (TV: Doctor Who and the Silurians, The Mind of Evil, Invasion of the Dinosaurs, Planet of the Spiders)

Typically, the Doctor would defeat his mechanical-based adversaries by "[reversing] the polarity" of their machines. (TV: The Dæmons, The Sea Devils, The Time Monster, Carnival of Monsters, Planet of the Daleks, Invasion of the Dinosaurs, The Five Doctors)

The third incarnation preferred lime to lemon in his drinks, (PROSE: Verdigris) and occasionally performed magic tricks, some of which he owed to escape artist Harry Houdini. (TV: The Ambassadors of Death, The Three Doctors, The Monster of Peladon, Planet of the Spiders)

Skill
The Third Doctor was a master of Venusian aikido, (TV: Inferno, The Mind of Evil, The Claws of Axos, Day of the Daleks, The Sea Devils, The Green Death, Invasion of the Dinosaurs) Martian karate, (PROSE: Inferno) and many additional forms of unarmed combat, (TV: The Three Doctors, Planet of the Spiders) despite never receiving any prior training in combat, (PROSE: Placebo Effect) expect for boxing, which he learned from John L. Sullivan. (TV: Carnival of Monsters) He was also a skilled swordsman, able to best in two continuous sword fights. (TV: The Sea Devils)

The Doctor's knowledge of the TARDIS greatly increased in his third incarnation, chiefly due to him taking it completely apart and reassembling it to try and make it work. (TV: Inferno, The Claws of Axos, Day of the Daleks) Once the Time Lords returned the knowledge of how to operate it after he assisted in the defeat of Omega, (TV: The Three Doctors) the Doctor was more adept at controlling his destinations than his previous incarnations, who often lacked any sort of control over the TARDIS. (TV: An Unearthly Child, The War Games, The Green Death) He denied any mistake on his part if he strayed, but would eventually find he had been interfered with, rather than his navigation being faulty. (TV: Carnival of Monsters)

The Doctor was able to break states of hypnosis caused by others, (TV: Terror of the Autons, The Time Warrior) and could also resist forms of hypnosis which would defeat weaker-minded individuals, such as BOSS's conditioning at its strongest power frequency. (TV: The Green Death)

The Third Doctor was a skilled diplomat, (TV: The Curse of Peladon) and linguist, (TV: The Mind of Evil , Planet of the Spiders) as well as having a knack for disguises, even altering his voice for his characters. (TV: The Green Death, The Time Warrior) He was also an acclaimed singer, taming the Aggedor with a Venusian lullaby. (TV: The Curse of Peladon)

Appearance
The Third Doctor looked like a man in his fifties, with a shock of white hair, a pronounced chin and a big, pointy nose. He disliked his features at first, but soon found himself 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)

The Fifth Doctor described his third incarnation as an "aristocrat". (PROSE: Five Card Draw)

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
The third incarnation of the Doctor gradually moved from a flat, rather inconspicuous short-cut hairstyle to an ever-more voluminous and exuberant bouffant. (TV: Spearhead from Space, 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)

Clothing
Unlike his previous two incarnations, who kept to a more straight forward wardrobe, the Third Doctor wore many different variants of the same design.

He wore frilled shirts, velvet smoking jackets and Inverness cape outfits. (TV: Spearhead from Space) He also wore a bow tie or cravat. Other times, he would don a jabot or a pendant. (TV: Spearhead from Space, Doctor Who and the Silurians, The Mind of Evil , The Three Doctors)

The third incarnation of the Doctor was also keen on wearing decorative rings, and riding gloves when driving Bessie or outdoors in general.

Because of his more frilled fashion, his first incarnation sneeringly called him a "dandy," (TV: The Three Doctors) while his second incarnation labeled him "fancy pants". (TV: The Five Doctors)

Mysteries and discrepancies

 * The newly regenerated Doctor sported a tattoo on his right forearm. The image was of a snake, coiled into the shape of a question mark. (TV: Spearhead from Space) One account suggested this was the mark made by the Time Lords to signify the Doctor was an exile. (PROSE: Christmas on a Rational Planet)
 * The Doctor implied on two occasions that he was thousands of years old. (TV: Doctor Who and the Silurians, The Mind of Evil)
 * See separate article.

Casting
Ron Moody was approached by the producers after his success in "Oliver" 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.

Other matters

 * "Reverse the polarity of the neutron flow" was often thought to be this incarnation's most commonly-used quote. He in fact 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 claimed 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, visible on screen in Spearhead from Space, was left over from Pertwee's days in the military.
