Third Doctor

The Third Doctor was the third incarnation of the Time Lord known as the Doctor. Throughout the bulk of his life, he was exiled by the Time Lords on Earth. This frequently made him bitter.

This Doctor entered the service of United Nations Intelligence Taskforce as their unpaid scientific advisor. He remained in their service long after his exile was ended. Unlike his earlier incarnations, he was eager to engage others physically. He also cut a more dashing figure.

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

In the field, the Doctor was aided by Sergeant Benton, Captain Mike Yates and even the Brigadier himself. The Doctor did not get along well with the Brig at first, but they became good friends, an easy mutual trust developing between them.

After Liz left, the Doctor was given a new assistant, Jo Grant. She was bubblier and less scientifically-inclined. The Doctor found her a most useful companion in his adventures during and after his exile. Jo got in trouble easily and the Doctor became protective of her. She left UNIT to marry Clifford Jones.

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

The Third Doctor regenerated 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. His knowledge of TARDIS operation was blocked. (DW: The War Games) When his regeneration was complete, (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.

When the Doctor arrived, 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 could animate humanoid facsimiles called Autons. The Nestene Consciousness took over a toy factory in London. It 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. However, 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)

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 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.

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)

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

The Doctor and Jo were joined by Liz Shaw for the TARDIS' maiden voyage. They travelled to December, 1916, where they encountered Rasputin, a famous phycic who talked with them. Liz was brought to authorities after it was learned she disliked him, basing her beliefs on history. Later, the authorities, who also disliked him, invited him to a house, where they planned to kill him by poison. Jo saw the men poisoning his food and-thinking that it was a plan to kill everyone-she replaced it with non-poisioned food. Felix Mather, noticing that he has not died from the poisioning, shoots him in the back, then goes to celebrate. Rasputin, who had survived the shot, tried to escape the house, but was gunned down again, and then dumped in a lake. The Doctor went to save him, but was too late, and was unable to retrieve him from under the ice in time. (PDA: The Wages of Sin)

The Doctor and Jo then travelled through time to kill a baby that would grow up to be a dictator, but found himself unable to do it. (ST: Categorical Imperative)

The Doctor and Jo then were sent to a planet where a computer put them up to multiple deadly games and intelligence questions. The Doctor defeated it by asking a question that was impossible to answer. (DWAN: The House That Jack Built)

The Doctor and Jo then encountered a creature that wished to live forever, but needed the Doctor's body to do so. Jo was able to overcome its hypnotism and the creature died. (DWAN: Revenge of the Phantoms)

Back at UNIT HQ, the Doctor detects a hole in the space-time continuum, and tries to close it, but luckily first he is able to be reunited with Jo. The Doctor explains that Jo had been sent to another Earth in an unstable state, which had caused the other Jo to appear to die. The Doctor had sent a message to his other self to retrieve his Jo. (DWAN: Dead on Arrival)

The Doctor then visited Freedonia, a plane that he had been to before, when helping in the revolution. He discovered that all the people were now slaves to Kamoa, one of the leaders in the revolution who is now nothing more than a brain. Jo was able to convince Bolgar, one of Kamoa's servants, to unplug the brain, thus freeing all of the citizens. (DWAN: After the Revolution)

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 discreetly left to return to UNIT HQ. (DW: The Green Death)

Sarah Jane Smith
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 Goodwood, 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. (BBCR: Glorious Goodwood)

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.
