Second Doctor

Though outwardly warm, bumbling and clownish, the Second Doctor also had a darker, more cunning aspect to his personality — one which he usually kept hidden in order to carry out his plans. Regenerating when his first incarnation gave in to old age and fatigue following his fight with the Cybermen, this new incarnation was the product of the Doctor's first regeneration.

He travelled with a number of companions, starting with his previous incarnation's last companions, Ben Jackson and Polly Wright, before adding Highland Scot Jamie McCrimmon to the TARDIS. After a while, Ben and Polly left, to be replaced by Victoria Waterfield, a woman orphaned by the Daleks. In time, she too left, and the Doctor made a new friend in the mentally gifted Zoe Heriot. At some point, he also travelled with his grandchildren, John and Gillian.

His adventures came to an end when he called on his people for help with the evil machinations of the War Lords. Though the Time Lords did indeed render assistance, they also condemned him to exile on Earth and a new body for breaking their non-interference policy many times over. The Celestial Intervention Agency was able to stay the execution of this sentence for a while in exchange for the Doctor providing his services to them. During these later years of his life, the Second Doctor variously carried out covert operations for the CIA and lived in luxury and fame in the heart of 1960s London. Eventually, though, Time Lord justice reasserted itself, and the Doctor was indeed forced to regenerate into his third body.

A day to come
When the First Doctor was a young boy studying at the Time Lord Academy, Borusa gave him a lecture on regeneration, telling him he would "walk into a storm and a stranger [would] walk back out, and that [the] stranger [would] be [him]." (PROSE: The Day of the Doctor)

While living on Gallifrey, there was a rumour that the Doctor was able to glimpse his first seven regenerations during a game of Eighth Man Bound. (PROSE: Christmas on a Rational Planet, Lungbarrow)

Susan Foreman predicted to the First Doctor that he would "grow younger" as the years went by. (PROSE: The Longest Story in the World) The Doctor himself would occasionally have premonitions of his future incarnations. (PROSE: A Big Hand for the Doctor)

While contemplating his sacrifice to satisfy the Web of Time, the First Doctor reflected on regeneration, and the person he could become when he regenerated. (AUDIO: Men of War)

Shortly after he met Katarina, (PROSE: Scribbles in Chalk) and especially after his struggle with the Celestial Toymaker, the First Doctor began to feel he was nearing the end of his life, becoming increasingly unwell, (PROSE: The Man in the Velvet Mask) and was afraid of the change. (PROSE: Ten Little Aliens) After he was joined in his travels by Ben Jackson and Polly Wright, (TV: The Smugglers) the First Doctor was aware that his regeneration was nearing. (PROSE: Ten Little Aliens, Five Card Draw)

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

Post-regeneration
After having the "stuffing knocked out of him" fighting the Cybermen in Antarctica in December 1986, (COMIC: Blood and Ice) and after coming to terms with the change, (TV: Twice Upon a Time) the Doctor regenerated on the floor of his TARDIS, his appearance changing into that of a much younger man. (TV: The Tenth Planet) After the regeneration, which he referred to as a "renewal", was completed, the new Doctor found himself suspected as an impostor by Ben, this being due to the Doctor failing to inform his companions of the Time Lord's ability to regenerate, while Polly was more ready to believe that he was the same Doctor.

Before he had time to recover, the TARDIS landed on Vulcan, where the Doctor witnessed the murder of an Earth examiner sent to check on the human colony. Posing as the examiner, the Doctor tried to stop the colony's scientist, Lesterson, from reactivating three captured Daleks, but failed. Sceptical about the apparent reformed Daleks serving the colony, the Doctor desperately tried to convince the humans that they were using their colony to produce new Daleks. By the time Lesterson uncovered the truth, it was too late: Thousands of Daleks, now showing their true colours, attacked the colony and killed many colonists. The Doctor and his companions remained to fight alongside the colonists, with the Doctor destroying his foes by using their power against them, and exposing security head Bragen as the murder of the examiner. (TV: The Power of the Daleks)

Immediately after leaving Vulcan, the Doctor, Ben and Polly briefly encountered a "ghost" in the TARDIS, while the Doctor was also avoiding Polly's questions about possibly meeting the Daleks again, (AUDIO: The Light at the End) as he was mourning the loss of his signet ring, until he decided it was replaceable. (COMIC: The Chameleon Factor) Soon after regenerating, the Doctor met Lilith on the Panjistri homeworld, when the Timewyrm had been recuperating in his mind since his regeneration. However, the Timewyrm passed from the Doctor to Lilith. (PROSE: Timewyrm: Apocalypse)

New adventures with Ben and Polly
The Doctor, Polly and Ben came across the body of a terraformer on Pluto's moon, Charon, and prevented a shadow creature from escaping its capture after Professor Magellan and his spacecraft crew set it free by killing the beings who had imprisoned it. (PROSE: Pluto)

The Doctor, Ben and Polly fought a mechanical grasshopper whilst taking a stroll on an alien planet. (PROSE: The Sour Note) On Dorada, they were enslaved by the Masters of Dorada, having their memories altered so they wouldn't remember living anywhere else and being forced to work in their factories. They were freed by two rebel Doradans, but refused to assist them in killing the Masters. Shaken after watching the deaths of the rebels, the Doctor and his companions shut down the machines controlling the Masters' life processes. (PROSE: The Dream Masters)

The trio then visited a planet where blonde-haired people were considered inferior to those with dark hair. The Doctor defended the blonde-haired people to the ruler of the planet, who put them through the Tests of Trefus, which they won and were accepted into society. (COMIC: The Tests of Trefus) On his own, the Doctor played a part in preventing the extinction of the Tryods. (PROSE: The Word of Asiries)

After landing on an Arcturian spaceship under the impression it was hostile, the Doctor was greeted by a peaceful species from Arcturus, who had fled from their own planet after losing the atmosphere. Knowing humanity would consider them a threat and fight them, the Doctor altered their time co-ordinates and transported their fleet to the Ninth Dimension, where they could find a new world to call home. (PROSE: Only a Matter of Time)

The Doctor took Ben and Polly to the idyllic planet Harmony. However, he learnt the population were harvesting visitors for food as the planet's animals had all died out. Barely escaping with his life, the Doctor collected his companions and fled in the TARDIS, not telling Ben and Polly about his gruesome discovery. (PROSE: Planet of Bones)

After exploring the vast emptiness of space, (PROSE: When Starlight Grows Cold) the Doctor, Ben and Polly next travelled to the "planet of Light", before an eclipse that plunged the planet into darkness began. Teaming up with an ancient resident called Igor, the Doctor helped the citizens overcome their fear of the dark, and parked the TARDIS in orbit as the planet fell into darkness. (COMIC: World Without Night)

The Doctor tried and failed to change history by preventing Horatio Nelson from being killed during the Battle of Trafalgar, (PROSE: H.M.S. TARDIS) and next fought grave robbers in the tomb of king Pharaoh Tut-Ankh-Amen in Egypt. (PROSE: The King of Golden Death)

The Doctor, Ben and Polly stopped an elemental force called Saint Nick from feeding on the energy of those who believed in Christmas. (PROSE: The Feast)

The Doctor, Ben and Polly then encountered Cat-People and Euterpians in 1994, where Polly's latent psychic powers were nearly used to trap Earth's essence in a small ball before the Doctor trapped one Euterpian in a time loop and tricked the other into destroying itself by triggering its powerful song inside the TARDIS. (PROSE: Invasion of the Cat-People)

The TARDIS crew met Draconians, Alpha Centaurans, and Venusians in a bar, before a strange signal drew them to the Hotel Galaxian, where the Doctor had to prevent the Selachians getting their hands on a lethal computer program that could turn any existing computer system into a weapon against its assigned target. (PROSE: The Murder Game)

On holiday in Hollywood in 1947, the Doctor's investigation into the death of his old acquaintance, Harold Reitman, led to the discovery that producer Leonard De Sande was working with an alien race he called the Selyoids, his plans essentially bringing peace to the world at the cost of making everyone blindly devoted to the Selyoids. Polly briefly fell under the Selyoids' influence, but the Doctor and Ben were able to help her realise what she had become. (PROSE: Dying in the Sun)

The Doctor and his companions next stopped off in San Francisco in 1967, where they joined the search for Jessica Willamy's boyfriend, Denny Glass, and discovered he had been recruited by a shadow government known as the Combine, who were making and spreading Blue Moonbeams, a more dangerous drug than LSD. (PROSE: Wonderland)

The Doctor travelled to Draconia during the reign of the Fifteenth Emperor. He cured a plague from space and was made a noble of Draconia for his actions. (TV: Frontier in Space; PROSE: The Dark Path)

Joined by Jamie
Arriving in Scotland after the Battle of Culloden in 1746, the Doctor, Ben and Polly met young Highlander Jamie McCrimmon. After exposing Solicitor Grey as a slave trader, they invited him to come with them in the TARDIS, which he accepted. (TV: The Highlanders)

With Jamie now in tow, they next landed in the lost city of Atlantis, where the Doctor met Professor Zaroff, a well renowned scientist who had created a way to harness plankton into edible food. The Atlantians let him stay under the promise that he would raise their city from the sea. The Doctor realised this plan would destroy the Earth and tried to convince their leaders, to no avail. They managed to foil Zaroff's plan by flooding the city, and thereby saved the Earth. (TV: The Underwater Menace)

The travellers then fought the Cybermen at the Moonbase, (TV: The Moonbase) and encountered the Macra on an Earth colony. (TV: The Macra Terror)

They later arrived in Vichy France on a train-line, and the Doctor had to abandon the TARDIS to find where Ben and Jamie had been taken by the Malise. (AUDIO: Resistance)

When the TARDIS landed in Kent in 1920, it was hit by a train. The Doctor was delighted when he met the Signalman and started to talk about train regulations. When Ben told him that he could see dead navy officers, whilst Jamie saw highland soldiers, the Doctor theorised that they were created due to the grief of the nation and the broken telepathic circuit of the TARDIS. (AUDIO: The Mouthless Dead)

The Doctor was concerned when the TARDIS crashed into something and it shoved them back in time by thirty-five years. When he realised that the Earth they were on was greying and lifeless, he explained to Polly that something was sapping the energy from the Earth. He encountered the Vist and theorised that they saw time like humans saw space. He tried to persuade the Vist that they could lock off a section of time and make people pay a toll for living in that time. He tricked them into going back in time to the Big Bang and they blinked out of existence. (AUDIO: The Forbidden Time)

After landing near the Galacti-bank, the TARDIS got impounded for not paying a parking ticket. Soon after, the Selachians attacked the bank looking for something. The Doctor managed to negotiate the release of some of their hostages and to find a way to stop the Selachians from stealing from the vault. (AUDIO: The Selachian Gambit) They later landed in a casino run by the Sidewinder Syndicate. The Doctor had an illegal device planted on him, which Polly used to escape the Sidewinder Syndicate. (AUDIO: House of Cards)

The Doctor decided to teach Ben and Polly how to pilot the TARDIS, but the TARDIS faltered in the vortex and deposited them in New Houston, a place the Doctor had visited with Dodo Chaplet. When he realised that his old friend, Meg Carvossa, had been murdered, he promptly investigated it, but soon discovered that she wasn't dead. (AUDIO: The Yes Men)

The TARDIS landed in Kenga, Singapore during World War II, where the Doctor was taken to the nearby hotel by Clive Freeman. When both Polly and Jamie saw a vision of the Grim Reaper, he went looking for it and accidentally set off Jamie's trap. Whilst examining a piece of alien technology, he was visited by the Forsaken. After Maggie Bishop was killed, Polly helped the Doctor search for clues. (AUDIO: The Forsaken)

Next, the group met and defeated the Chameleons at Gatwick Airport on 20 July 1966. After realising that they had arrived home on the same day they had originally left, Ben and Polly parted company with the Doctor and Jamie, opting to remain on Earth in their own time. (TV: The Faceless Ones)

Looking after Victoria
After the TARDIS was stolen at the behest of the Daleks, the Doctor and Jamie found a time corridor and were transported back to 2 June 1866, where they found two 19th century human scientists, Edward Waterfield and Theodore Maxtible, trying to isolate the Human Factor. Jamie and the Doctor befriended Waterfield's daughter, Victoria. After Waterfield died protecting the Doctor, and the introduction of the Human Factor into some Daleks instigated a civil war on Skaro, the Doctor and Jamie left with Victoria, believing the Daleks had destroyed each other. (TV: The Evil of the Daleks)

With Jamie and Victoria alongside him, the Doctor aided an archaeological team on Telos in opening a Cyber-tomb. Eric Klieg awakened the Cybermen and the Cyber-Controller from their five-hundred year slumber, but the Doctor and Jamie sealed them away again. The Doctor electrified the entrance, the hatch leading to the tombs and the symbolic logic controls to prevent anyone else from entering. (TV: The Tomb of the Cybermen)

Returning Victoria to her original time, the Doctor was introduced to the recluse Sir Charles Westbrooke, who had reanimated six dead people in an experiment to bring his wife back to life. However, he was killed when it was revealed that he was his wife's killer, and as the animated corpses rampaged, the Doctor cooked up a formula, filled a rifle with tranquilliser darts and defeated the deceased with Victoria's aid. (PROSE: The Age of Ambition)

When the TARDIS landed in Sumatra, the travellers found the Great Space Elevator, a method of reaching a space station without using rockets, and arrived just as the space station lost power. When the Doctor found a way to get to the space station to discover the cause of the problem, the crew claimed that there was nothing wrong, but a member of the crew told the Doctor that the crew was infected by static electricity, which allowed the humans to be conductive. (AUDIO: The Great Space Elevator)

Reunited with Edward Grainger, the Doctor discovered a slave race called the Virtors had been transporting New York Supplementary Education Institution students back to their home world of Virtus. He prevented them from capturing Victoria, Jamie and Edward, but accidentally fell into their portal to Virtus himself. Trapped on Virtus for a long period of time, the Doctor led a slave rebellion and, eventually, led the ageing humans back home, merely seconds after he had originally left from Earth's perspective. (PROSE: The Lost)

The Doctor took Jamie and Victoria to an alien arena to watch a fight between soldiers and a dragon. However, the Mantis mistook the travellers for pirates and threw the Doctor into the arena to fight the dragon, where he played a tune on his recorder to enthral it and set it upon the audience, who fled. (PROSE: Valley of Dragons)

After escaping the destruction of a civilisation in the Uranium Universe, (COMIC: Atoms Infinite) the Doctor and Jamie were taken prisoner by the Cogwens on Pendant, but they were rescued by Victoria and a gang of outcasts, just in time for the Doctor to stop the Cogwens from stealing the TARDIS. (PROSE: World of Ice)

Attempting to bypass the anti-theft protocols in the TARDIS that allegedly prevented him from controlling the TARDIS himself, the Doctor accidentally disabled so many security protocols that the ship materialised in a pocket dimension containing the displaced town of Lychburg. The pocket reality prevented the Doctor, Jamie and Victoria from returning to the TARDIS. Determining what they were dealing with, the Doctor unintentionally disrupted the control of the entity manipulating the pocket dimension when a doctor who was trying to plant a control device in the Doctor's neck accidentally stabbed himself in the gut. After the Doctor tracked the controlling entity to a prototype TARDIS, Jamie killed the controller, the last Gallifreyan Woprat in existence, and unintentionally caused the final collapse of the pocket dimension. The Doctor then regained access to the TARDIS when someone modified the dimensional settings from inside the ship, but this gave him time to implement a plan and evacuate Lychburg's entire population into the TARDIS and take them to safety once the pocket dimension collapsed. (PROSE: Heart of TARDIS)

On Earth, the Doctor fought against the Robot Yeti and the Great Intelligence in the Himalayas, (TV: The Abominable Snowmen) and returned to Earth again in a new Ice Age, and discovered Ice Warriors buried in the ice. (TV: The Ice Warriors)

Missions with Jamie
The Doctor, Jamie and Victoria landed on a human spaceship where they aided a Gallifreyan calling himself "Constable Pavo of Chapter 9" with his investigation of a nearby artificial black hole. While Victoria stayed behind with him, Pavo sent the Doctor on a mission to Space Station Camera, but they fled when they saw the Station attacked by Sontarans.

After visiting the City of Owls and helping the people of McKenzie, the Doctor and Jamie returned to the ship they departed from before they actually first arrived on the ship, and found the real Pavo, helping her to defeat, after which Pavo agreed not to arrest the Doctor, but erased the Doctor and his friends' memory of the event nonetheless. (AUDIO: The Black Hole)

Final adventures with Victoria
The Doctor befriended Stuart Mallory, a distinguished naturalist, with whom he and his two companions later took to dinner. (PROSE: The Last Emperor)

The Doctor visited East Ridge, where he helped a farmer called Thomas Watson to protect his family's farm from ruthless New York businessman, John Glassman, turning the whole town against the Watsons. The Doctor, Jamie and Victoria managed to expose John's dishonesty to the town's sheriff, which saved Watson's farm and place within the town. (PROSE: The Farmer's Story)

Whilst Jamie slept in the TARDIS, the Doctor took Victoria to a pub, where he annoyed locals with his tales of Saint Nicholas. When sailors from Bari arrived, the Doctor got them drunk, snuck onto their ship and retrieved the bones of Saint Nicholas, which they had just stolen. Later, he and Victoria buried the bones in the North Pole. (PROSE: Saint Nicholas's Bones)

The Doctor set the TARDIS controls for both his friend William Shakespeare's house in Stratford and the Pan-Galactic Games on Alpha Centauri, as Victoria had wanted to see how her ancestors had lived in the late 16th century and Jamie had wanted some excitement and spectacle, reasoning that he stood a fifty-fifty chance of arriving at one or the other. Instead, to their disappointment, they materialised in Australia in 2018. The Doctor briefly wondered if something was causing the TARDIS to keep coming back to Earth, but dismissed the thought. (PROSE: Timewyrm: Apocalypse) The Doctor met a double of himself in dictator Ramón Salamander. (TV: The Enemy of the World)

During a second battle with the Great Intelligence, the Doctor made the acquaintance of Alistair Gordon Lethbridge-Stewart. (TV: The Web of Fear)

Returning to 1960s London weeks after the Yeti invasion, the Doctor discovered a robot duplicate of Edward Waterfield had been created by the Daleks to exact revenge on him for destroying them in the 19th century. (PROSE: Father Figure)

After the TARDIS landed once more on Vortis, where the Doctor defeated the "seed" of the Animus he had encountered in his previous incarnation, (PROSE: Twilight of the Gods) the TARDIS crew travelled near the Darkheart. They encountered the war-like Veltrochni and Koschei, an old friend of the Doctor's from Gallifrey, travelling with Ailla. However, the temptation posed by the Darkheart device proved too much for Koschei, and the revelation that his companion Ailla was a spy destroyed the last traces of good in him, and he became. The Doctor had to trap him in a black hole. (PROSE: The Dark Path)

After a holiday in Grasmere, (PROSE: The Hollow Men) the Doctor, Jamie and Victoria travelled to Venus, where the Doctor learned Venusian aikido (AUDIO: Voyage to Venus) from "a many-armed glowing-eyed being in a misty cavern". (PROSE: Endgame)

Craving peace and quiet, Victoria left the TARDIS crew to live with Frank and Maggie Harris after an adventure on a Euro Sea Gas refinery with a weed creature. (TV: Fury from the Deep)

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

John and Gillian
After the Doctor reunited with his two grandchildren, John and Gillian, and he saved every planet in the universe from being attacked by missiles that had been programmed by the Extortioner in his scheme to hold every government in the universe to ransom. (COMIC: The Extortioner)

Taking John and Gillian in the TARDIS with him, the Doctor planned to sign a peace treaty with the Trods of Trodos. However, he found that he had been lured into a trap by the Daleks. Escaping before they could kill him, the Doctor allied with surviving Trods to free Trodos from Dalek control. Leaving the planet, the Doctor swore that he would never flee from the Daleks again, and that in their next encounter they would meet on his terms. (COMIC: The Trodos Ambush)

Leaving Trodos, the Doctor found a Dalek ship was chasing his TARDIS through the time vortex, which eventually forced him to return to the 22nd century at the height of the Dalek Empire. He disguised himself as a Dalek and foiled Dalek Supreme's plot to create thousands of Daleks. When he was detected, the Doctor used his disguise to trick all Daleks into destroying each other, before making a quick exit in the TARDIS with his grandchildren.

Deciding that his excursions in the TARDIS were becoming too dangerous, the Doctor enrolled John and Gillian at Zebadee University, telling his reluctant grandchildren that it was to improve their education. (COMIC: Invasion of the Quarks)

Travelling with Jamie again
After the Doctor successfully convinced John and Gillian to stay on Zebadee, the TARDIS brought him to a Scottish castle in 1967, where the Doctor found the Quarks preparing to launch an invasion. Having been spotted, the Doctor retreated into the castle, where he was saved from a Quark by Jamie, who had come to investigate the flying saucer in the castle. Coming up with a plan, the Doctor and Jamie commandeered the flying saucer and opened fire on the Quark invasion force, causing the Quarks to destroy themselves in the confusion. Returning to destroy the Quarks at the castle, Jamie and the Doctor both agreed to accompany each other in the TARDIS again. (COMIC: Invasion of the Quarks)

While he repaired the TARDIS' time rotor, the Doctor sent Jamie out to find gold, mercury and Zeiton-7. When he returned, Jamie had been given the Necronomicon by, which transported the Doctor and Jamie to the Great Desolation after the Doctor handled it. There, the duo discovered that the Master had been working with the Archon, who wanted to seize a TARDIS to attack the Time Lords. After they repaired the TARDIS, the Doctor defeated the Archon by playing his recorder whilst Jamie played the bagpipes, which confused and destroyed them. (PROSE: The Nameless City)

Landing on Gano after a war on the planet was lost, the Doctor and Jamie were attacked by giant wasps, but were able to evade them in a trench. Utilising a discarded anti-aircraft gun, they were able to shoot down a wasp, until the swarm changed formation and tackled the gun over, but exposed an underground city to the Doctor and Jamie in the process. Escaping into the city, the duo were confronted by the Quarks, but were able to avoid them using some old scooters, until they came upon a dead end. However, the wasps arrived to attack the Quarks and the battle between them enabled the Doctor and Jamie to make a break for the exit. After a close encounter with a wasp near the exit, which resulted in the creature's demise, the Doctor and Jamie made it to the TARDIS and left. (COMIC: The Killer Wasps)

After the TARDIS was forced to materialise by an explosion in 1970 Antarctica, the Doctor and Jamie discovered that aliens were threatening to detonate explosions to throw Earth off its axis.

Winning the duel with the bulldozer, the Doctor and Jamie made to leave, but were ambushed by the jungle natives enslaved by the Quarks. Forced behind the bulldozer's shovel, the Doctor removed the machine's silencer to frighten the jungle animals into stampeding onto the Quarks. Using the bulldozer to free the TARDIS, which had sustained no damage, the Doctor and Jamie departed the jungle. (COMIC: Jungle of Doom)

When the TARDIS landed in the Time Temple, the Doctor and Jamie were greeted by Father Time, who decided they needed to be punished for their time travel, and rendered them unconscious. The Doctor awoke to find himself tied to a pendulum lowering him into boiling oil, and Jamie sealed within a giant hour glass. Noticing a loose bolt, the Doctor increased the strain of the pendulum until it collapsed on itself, and also landed on the hour glass, freeing Jamie as well. With Father Time after them, the Doctor took shelter in a cuckoo clock, but Father Time cornered him there. The Doctor was saved by Jamie's intervention, but broke his ankle in the process. Whilst Father Time summoned robots after them, the Doctor was defended by Jamie, who inadvertently damaged the robots enough to set them on Father Time, giving him and the Doctor the chance to escape the Time Temple. (COMIC: Father Time)

After the Doctor completed constructing a mechanical housemaid named Martha, the TARDIS landed in 1971 New York City, where the Doctor and Jamie went to see C. G. Slattery of the Inventions International Company, who was impressed enough with Martha to put the Doctor on nationwide television to sell hundreds of thousands of Marthas. After a few weeks of successful business, however, the Marthas were taken over by the Quarks to be used as an invasion force. Though the Doctor was able to bring the Marthas back under his control, the Quarks soon arrived to take New York City by force, but the Doctor was able to turn the Marthas savage again to fight back against the Quarks. When the Quarks finally retreated, the Doctor was hailed as a hero, and even nominated for President of the United States. (COMIC: Martha the Mechanical Housemaid)

They were saved when the beastie was subdued by Eva De Ville. (COMIC: Where's the Doctor?)

Zoe joins the duo
The Doctor and Jamie fought the Cybermen on Space Station W3 and one of the space station's crew, scientist Zoe Heriot, stowed away aboard the TARDIS. The Doctor tried to dissuade her by using a thought scanner to show her how he ended the Daleks, (TV: The Wheel in Space) but the Daleks frightened her more than he had anticipated, and he apologetically conceded that the TARDIS could use another genius aboard.

Forced to land on a planet orbiting a pulsar in 2724 after two beams of energy from a pulsar collided with the TARDIS, the Doctor, Jamie and Zoe found themselves helping Dr. Sophie Topolovic and her crew rebelling an incursion on Topolovic's base, which was studying the altercations to time on the planet. Staying behind in the control room to let the others escape to the surface, the Doctor searched for another way out. In the base's observation room, the Doctor was told by a future incarnation via the psychic paper to return to the control room and save Dr. Topolovic's research, and discovered that the attackers were the Quiet Ones, the inhabitants of the ancient city Topolovic was studying. With this information, the Doctor spent several years negotiating with the Quiet Ones, until a truce could be formed. After helping the Quiet Ones repair the base and build a better communication device, the Doctor then retrieved Jamie, Zoe and Topolovic's team, with only a few moments passing for them, to inform them of the newfound peace. (AUDIO: Shadow of Death)

Arriving on the abandoned Skybase in 2069, the Doctor was shot while trying to escape, nearly regenerating before an injection of Shiner DNA stabilised his rewiring DNA and kept him alive long enough for his body to heal naturally, although it took six months for him to come out of the subsequent coma. Aware from his link to the Shiners that the Myloki were returning to Earth, the Doctor assisted in the search for the immortal captains Karl Taylor and Grant Matthews. Taylor was killed after Jamie accidentally released him. The Doctor subsequently accompanied Matthews to confront the Myloki, allowing Matthews to join them as he speculated that the Myloki, far from being evil, simply couldn't understand humanity and required Matthews' perspective.

A busy few weeks
When Zoe noticed that a Cyber-ship had escaped the explosion of the cyber-fleet, the Doctor traced it to the planet Isos II. Once there, they encountered friendly giant slugs. The Doctor was later captured by Ison Security agent Enab and questioned by Seru. When Seru showed him a map of the underground network, the Doctor went there to look for Zoe. He saw that the slugs were using the cyber electricity conjunctions boxes to breed. He got onto the train that the Cybermen wanted to run into him, and discovered that it was a spaceship destined for Earth. The Doctor was taken to the Cyber-Controller, who wanted to take all of the Doctor's knowledge so they could invade Earth. The Doctor worked out that the only way that he could stop the Cybermen was to blow up their new spaceship by putting it into a warp ellipse, but that meant sacrificing himself. Hilsee decided that he should be the one to do it, and forced the Doctor off the ship. (AUDIO: The Isos Network)

After Zoe had cut her hand making Haggis, the TARDIS landed at the Whitaker Institute. The Doctor managed to bluff his way into being a station inspector, and worked out that the Achromatics were based on Dorian Gray's portrait. He destroyed the research in order to stop them being used for war. (AUDIO: Echoes of Grey)

The TARDIS then landed on Earth near a funeral of a scientist, as the Doctor had lost control of the ship. Wanting to know what had affected the TARDIS, the Doctor found out that the machine at a nearby research facility was accidentally venting energy into the space-time vortex and he fixed the machine to stop it.

He also uncovered a conspiracy stretching back to the colony's foundation a century earlier: the planet was already inhabited by the Tyrenians before the humans arrived. With some brief assistance from the Seventh Doctor, the Second Doctor was able to prevent a war by negotiating a peace settlement between the Tyrenians and the humans. He also foiled a rogue Federation plot to kill everyone on the colony to allow the inbound refugees to start afresh. After the crisis, the Federation agreed to respect the colony's independence. (PROSE: The Colony of Lies)

The Doctor traced a disturbance in the time field to France in the 14th century. Shortly afterwards, he found out that there was a visionary. Upon seeing Marie's relics, he realised that time had been scrambled as the relics came from the future. Zoe later showed him a tank in the courtyard which confirmed what he was thinking.

Arriving in Scotland, the Doctor, Jamie and Zoe accidentally inspired Macbeth to slay the Scottish king. Afterwards, Macbeth confused the Doctor and Jamie for assassins-for-hire, and the Doctor agreed to kill Banquo to ensure his escape, giving Banquo a perception filter to give Macbeth a fright. Needing to lure Macbeth into a false sense of security, the Doctor, Jamie and Zoe disguised themselves as three witches and convinced Macbeth that he needed to kill Macduff. Saving Macduff's family, the Doctor observed Lady Macbeth's obsessive compulsive sickness and helped organise the British Army's assault plan for Macbeth's fortress. Satisfied that history was put back on the correct course, the Doctor, Jamie and Zoe left. (PROSE: The True Tragedy of Macbeth)

After the TARDIS landed in the Frenko Bazaar, a famous intergalactic trading post where one could buy "just about anything", the Doctor, in an attempt to take down the slave market, placed a homing device on Jamie, and followed some Voraxx into Stellar Imports & Exports to gain their attention. A member told the Doctor that Jamie, coming from the past, was "worth a mint", but, when he said that Jamie wasn't for sale, the Voraxx members kidnapped Jamie, and took him aboard a slaver ship in orbit. Following Jamie's signal, the Doctor and Zoe found the trans-mat that led to the ship and found Jamie. They then awoke some Ice Warriors, who started an uprising.

Jamie stopped Curtis from taking him, but the Doctor had to quickly escape as the Edge began breaking apart due to his actions. (AUDIO: The Edge)

Trial
The Doctor and his companions landed on a planet where the War Lords planned to use human soldiers as an army to conquer the galaxy by picking them out of various periods of Earth's history with the War Chief's space-time vessel technology that had been given to them. The Doctor, Jamie and Zoe helped unite the various resistance movements on the planet to fight the War Lords. Unable to return all the kidnapped soldiers to their correct places in time and space, the Doctor called the Time Lords for help with a hypercube, thereby betraying his location to them, (TV: The War Games) following advice given to him by the Eighth Doctor in a time bubble. (PROSE: The Eight Doctors)

The Doctor, Jamie and Zoe tried to slip away before the Time Lords arrived, but the Time Lords started interfering with the TARDIS operation and demanded the Doctor hand himself over. Wanting to escape their detection, the Doctor materialising the TARDIS on an ocean and then in space, (TV: The War Games) and even briefly on the Ulk-Ra planet, where the Doctor reluctantly "switched off" Ossu-male. (PROSE: War Crimes) They continued their attempts to flee the Time Lords, but were inevitably caught and brought to the Time Lords' home planet, (TV: The War Games) Gallifrey. (TV: The Time Warrior)

After the Time Lords dematerialised the War Lord for his crimes, they placed the Doctor on trial for violating the non-interference policy of the Time Lords. Jamie and Zoe were taken away from him and had their memories of the time they spent travelling with him removed, save for their first adventure. After showing that his interfering with time actually helped prevent evils such as the Daleks, Quarks, Yeti, Cybermen and Ice Warriors from gaining significant power, his sentence was handed down. He was to be exiled to Earth in the 20th century with a forced regeneration. He was given a choice of new appearance, but rejected all of the choices. At their wits' end, the Time Lords chose his new face for him and sent the protesting Doctor away to begin his exile. (TV: The War Games)

After the trial
Before the sentence could be carried out, the Celestial Intervention Agency interceded, turning the Doctor into their "hired gun". In his first mission, he met the Players, an experience that resulted in the death of his assistant, Serena, and left his hair turning grey. (PROSE: World Game)

Wearing his fur coat, the Doctor had an adventure in an American park, where he briefly crossed paths with the Eighth Doctor and a version of Clara Oswald.

Returning to the CIA after taking "a few stops along the way", and using Serena's death as blackmail, the Doctor convinced Sardon to let Jamie travel with him again. Sardon conceded, and altered Jamie's memory to make him believe Victoria was away studying graphology. Sardon sent the Doctor to persuade his old friend, Joinson Dastari, to stop his experiments with time at the Space Station Camera. (PROSE: World Game)

Working with Jamie
With Jamie put under a "magic spell", (PROSE: The Two Doctors) the CIA sent him and the Doctor to persuade Joinson Dastari to stop Professors Kartz and Reimer's experiments with time travel at the Space Station Camera, (PROSE: A Brief History of Time Lords) but Dastari and his augmented Androgum, Chessene, had planned to kidnap the Time Lord emissary all along, partnering up with the Sontarans to steal the secret of time travel from the Time Lords' genetic makeup. The Sontarans slaughtered the station and the Doctor's death was faked to hide his kidnapping and seclusion in a hacienda near Seville.

Jamie escaped the massacre and reported everything to the Sixth Doctor and Peri Brown when they discovered him. The Second Doctor was transformed into an Androgum by Dastari and joined Shockeye for food at the Las Cadenas restaurant in Seville, but, because the operation was incomplete, the effect was only temporary. When Dastari and Chessene brought the Second Doctor, and his sixth incarnation, back to the hacienda, the Sixth Doctor sabotaged the attempted TARDIS copy invented by Kartz and Reimer, while Chessene regressed back to her Androgum nature. Dastari then freed the Second Doctor upon realising his mistake in augmenting a primitive Androgum, and was shot by Chessene for betraying her. The Second Doctor used his Stattenheim remote control to return his TARDIS to him, and he and Jamie left the hacienda in the TARDIS. (TV: The Two Doctors)

The Second Doctor teamed up with all of his other incarnations to save Gallifrey from destruction at the end of the Last Great Time War, but, (TV: The Day of the Doctor) shortly after meeting for tea with some of his other incarnations in the Under Gallery, (PROSE: The Day of the Doctor) lost all memory of the event due to the timelines not being synchronised. (TV: The Day of the Doctor)

Infiltrating the Blenhim ranks, the Doctor witnessed the Blenhim forces destroy every planet that refused to submit to their domination, and challenged the head Blenhim for the rule of the army. Winning the stand-off by using his laser-ring to destroy a local rock formation, but gaining a scar on his chest from the Blenhim's leader's laser eye vision, the Doctor was accepted as the new leader by the Blenhim. With his new powers, the Doctor instructed the Blenhim to fly east until given further orders, causing all of their forces to fly directly into a sun. (COMIC: The Mark of Terror)

Along with seven other incarnations, the Second Doctor became trapped in the Void when a Type 1 TARDIS from Ancient Gallifrey began to attack and devour the universe. He tried to avert the disaster by sending a hypercube to Alice Obiefune while the Eleventh Doctor was working on the early TARDISes with Rassilon, but his plan was unsuccessful. He and the others were able to form a dimensional bridge to allow the Eighth Doctor to escape, and were then joined by the War Doctor, followed shortly by the ninth, tenth and twelfth incarnations, who ventured into the Type 1 TARDIS.

Hiding in luxury
Now exiled, the Doctor took up residence in the Carlton Grange Hotel in London, (COMIC: Action in Exile) where he enjoyed considerable luxury and press attention, with people from around the world bringing their problems to him. (COMIC: The Mark of Terror, The Brotherhood, U.F.O.)

Death
While appearing on the game show Explain My Mystery, the Doctor was asked to consider the case of Mr Glenlock-Hogan, a farmer with walking scarecrows. He wasn't able to do so and arranged for an off-camera visit to the farm. Knowing it was a case so preposterous-sounding that it would not be taken seriously by anyone else but him, the Doctor wanted to investigate the matter privately. When he arrived, the scarecrows duly began to walk around. Eventually, they captured and shot him, revealing that they had been animated by the Time Lords in order to carry out the remaining part of his sentence.

The scarecrows dragged him to his waiting TARDIS, where they forced him to regenerate. During the process, the scarecrows programmed the TARDIS for a final flight, (COMIC: The Night Walkers) and edited the Doctor's memory to remove his knowledge of how to work his TARDIS, (TV: Spearhead from Space, The Claws of Axos) restrict what he knew about other alien species (PROSE: The Ambassadors of Death) and events beyond the 1970s, (PROSE: The Devil Goblins from Neptune) and make him think he had been executed at his trial. (PROSE: The Eight Doctors; AUDIO: Legend of the Cybermen, Stage Fright) Just before the Doctor's regeneration ended, his "entire past and future suddenly became clear to him" and, realising what he had done on the Panjistri homeworld, he sent a telepathic warning to his future self.

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

When the Ninth Doctor's Sin-Eater became conscious due to the Doctor's telepathic nature, it mutated to show the Second Doctor's face, among other incarnations, straining against its body. (COMIC: Sin-Eaters)

After the Eleventh Doctor was accused of committing deadly crimes against the Overcast, he brooded in the TARDIS for two days, imagining all his previous numbered incarnations, including the Second Doctor, interrogating him over the crimes. When he offered the rational that he always left things better than he found them, they all turned and left him in disgust and disgrace. (COMIC: Pull to Open)

When the Eleventh Doctor was investigating the War Doctor's actions during the Last Great Time War on Lujhimene, he briefly turned into the Second Doctor, alerting him to an ambush from the Then and the Now. (COMIC: Running to Stay Still)

When the Eleventh Doctor entered into the T'keyn Nexus in order to defend himself, Matrix projections of his previous incarnations, including the Second Doctor, appeared inside it to defend themselves as well. When auditor Sondrah accused the Doctor of allowing tragedy to happen, the Second Doctor defended himself by pointing out his inability to interfere with fixed points in time. When the Eleventh Doctor began to deduce Sondrah's true identity, the past Doctors faded away as Oscar Wilde interfered with the Nexus. (COMIC: Dead Man's Hand)

Alternate timelines
In an alternate timeline created by the Discordia, the Doctor had a passionate romantic relationship with River Song that began in his first incarnation, having married her by his fourth incarnation. In one of their outings, River convinced the Doctor to dress as Ramón Salamander for "fun". (AUDIO: Someone I Once Knew)

When the Cybermen allied with Rassilon to take over history, they manipulated the encounter at the Moonbase leading to the Second Doctor being partially cyber-converted. (COMIC: Prologue: The Second Doctor)

While aiding an archaeological team on Telos, (TV: The Tomb of the Cybermen) a Cyberman time squad attacked the Doctor. This would have killed him if their Controller didn't order them to stop at the risk of erasing their future invasion of Krelos due to the unwitting role of the Fourth Doctor in that plan. The Second Doctor then witnessed a Krelos robot drone decontaminate Jamie before time was reset and this interlude didn't happen. (AUDIO: Return to Telos)

In an alternate version of the London Event, the Doctor was killed by Colonel Spencer Pemberton in the London Underground. (PROSE: Legacies)

Personality
The Second Doctor was a complete change of pace from his predecessor - whimsical, somewhat buffoonish, yet still witty. Indeed, the slow transition of his original incarnation from a reluctant travelling companion to a more kindly compatriot was completed here, as the Doctor now very much enjoyed embroiling himself in adventures with his assistants, seeing that the "universe tend[ed] towards good". (PROSE: Wonderland) Despite his bluster and tendency to panic when events got out of control, the Doctor always acted heroically and morally in his desire to help the oppressed and fight "the most terrible things [in the universe]", (TV: The Moonbase, The Enemy of the World, The War Games) deeming himself the "enemy of anything that [was] wrong or evil in [the] universe". (PROSE: The Final Sanction)

He also had a warmer, gentler way about him than his previous incarnation. (TV: The Tomb of the Cybermen) Mercurial, clever, and always a few steps ahead of his enemies, at times he could be a calculating schemer who would not only manipulate people for the greater good, but act like a bumbling fool in order to have others underestimate his true abilities. (TV: The Evil of the Daleks, The Tomb of the Cybermen, The Web of Fear, The Wheel in Space) Although he frequently gave the impression that he never knew what he was doing, this was simply an act put on to fool those who would underestimate him. (TV: The Tomb of the Cybermen, The Dominators)

Despite the Doctor's almost childlike recklessness, it was always clear to his allies that a keen, deliberate intellect lurked behind his every action, (TV: The Macra Terror) with the Doctor adopting a grave seriousness when the situation called for it. (TV: The Mind Robber) Even though he could get caught up in events around him, the Doctor knew that his friends' wellbeing came first and foremost. (TV: The Abominable Snowmen)

The Second Doctor was very childlike in his love of play, dancing a jig in his new body, (TV: The Power of the Daleks) on the outskirts of Atlantis, (TV: The Underwater Menace) and a beach in Australia. (TV: The Enemy of the World) Unlike his reclusive predecessor, the Doctor was quite willing to enjoy fame, and even fortune, when he could find it. (COMIC: Martha the Mechanical Housemaid)

The Doctor liked champagne cognac, (PROSE: Foreign Devils) and cheesecake. (PROSE: The Juror's Story) He was also fond of Cluedo, (PROSE: The Menagerie) and had a fascination for jungles. (PROSE: Combat Rock) He was frightened of vampires. (PROSE: The Murder Game)

He also believed in destiny, telling Ben and Polly that the TARDIS' seemingly random journeys were controlled by destiny, and that "if [they] just obey[ed] destiny blindly, all [would] be well". (PROSE: Only a Matter of Time) When thinking about where the TARDIS would land, the Doctor hoped to find "pre-historic monsters." (TV: The Underwater Menace)

The Second Doctor was also painfully aware of the need to see the "bigger picture", knowing that it was entirely proper to sacrifice a few lives if it would save millions. (TV: The Evil of the Daleks, The Wheel in Space) In his more ruthless moments, he wired the Cyber-Tombs doors to fatally electrocute anyone trying to open them, (TV: The Tomb of the Cybermen) attempted to destroy the Great Intelligence by absorbing it into his mind, (TV: The Web of Fear) ensured that a relatively helpless party of Daleks would all die, (COMIC: Bringer of Darkness) steered an Ice Warrior fleet into the sun, (TV: The Seeds of Death) and used his ray gun to kill the Master of Spiders while shouting, "Die, hideous creature. Die!" (COMIC: Master of Spiders) He also appeared unfazed to Ramón Salamander's fate in the Time Vortex. (TV: The Web of Fear)

The Second Doctor had a noticeably antagonistic relationship with the Third Doctor, their personalities so different that they seemed incapable of working together without the authoritative presence of the First Doctor. (TV: The Three Doctors)

While the Sixth Doctor considered his second incarnation to be an "antediluvian fogey" for apparently being captured by the Sontarans, (TV: The Two Doctors) the Eighth Doctor remembered the Second Doctor as a "gentle little fellow who had sacrificed his own freedom so that others might be free". (PROSE: The Eight Doctors)

By the time he fought Side, the Doctor considered Jamie to be the most reliable friend that he had ever had. (AUDIO: The Jigsaw War) The Sixth Doctor even told his companion, Peri Brown, that he was "always very fond of Jamie." When Chessene of the Franzine Grig informed him that Jamie had most likely been killed in a Sontaran attack, the Doctor began going into a grief-stricken rage until he was restrained. (TV: The Two Doctors)

Victoria Waterfield saw the Second Doctor as a beacon of "kindness, compassion, wisdom, [and] great knowledge", (AUDIO: Power Play) with Zoe Heriot considering the Doctor to be a "lovely little man", who was "fun to be with." (PROSE: One Small Step...) On another occasion, she described him as "old, clever and kind." (AUDIO: The Five Dimensional Man)

River Song found the Second Doctor "fun, but [she] wouldn't trust him as far as [she] could throw him". (GAME: The Eternity Clock) When the Eighth Doctor had a tarot card reading, the Second Doctor was identified as "the Hermit". (PROSE: The City of the Dead)

When faced with a forced regeneration from the Time Lords, the Doctor, at first, was concerned over his next incarnation's appearance, maintaining that he had the right to decide what he looked like. After rejecting his offers, the Doctor protested that the Time Lords could not treat him the way they were, and continued protesting in the void, (TV: The War Games) until the Celestial Intervention Agency intervened. (PROSE: World Game)

When the forced regeneration was triggered after he was shot by the Time Lords' animated scarecrows, the Doctor used his dying breath to reassure Farmer Glenlock-Hogan, who had been ridiculed for seeing his scarecrows come to life, that the phenomenon would not happen again after the night was over. (COMIC: The Night Walkers)

Habits and quirks
The Second Doctor developed a habit of running away from danger when inappropriately prepared, often instructing his companions to retreat with, "when I say run, run!" (TV: The Power of the Daleks, The Faceless Ones, The Evil of the Daleks, The Tomb of the Cybermen, The Abominable Snowmen) He was prone to exclaiming, "Oh, my word!", when startled, (TV: The Ice Warriors, The Dominators, The Invasion, The War Games) intrigued, (TV: The Web of Fear, The Krotons, The Three Doctors) or annoyed. (TV: The Seeds of Death) Other favoured phrases of his were, "Oh, my giddy aunt!" (TV: The Krotons, The Three Doctors, The Two Doctors) and, "By the planets!" (COMIC: The Coming of the Cybermen, The Faithful Rocket Pack, The Time Museum)

Physical habits included wringing his hands together, (TV: The Faceless Ones, The Tomb of the Cybermen, The Mind Robber) shifting his jaw when pondering, (TV: The Krotons, The Three Doctors) and elbowing Jamie. (TV: The Faceless Ones, The Web of Fear)

The Doctor possessed a recorder, which he played to concentrate or while under stress. (TV: The Power of the Daleks, The Three Doctors) This recorder was also one of the Doctor's tricks of obfuscation, and he could use it as an effective tool, having a separate mouthpiece that turned it into a spyglass, (TV: The Wheel in Space) improvise it into a blowgun, (TV: The Underwater Menace)

He displayed a fondness of music in other ways besides the recorder, occasionally humming bits of music, (TV: The Krotons) and creating a glass harmonica out of a water glass to pick the sonic lock in his Vulcan Colony cell. (TV: The Power of the Daleks) He had a silent whistle and a pair of bagpipes and told Jamie he could trade travel on the TARDIS for lessons. (TV: The Highlanders) In Atlantis, he played his recorder and a small tambourine as part of his disguise. (TV: The Underwater Menace)

Skills
The Second Doctor had a gift for diplomacy and winning others over to his side, enabling him to trick others into doing what he wished, such as fooling Jamie into going through a series of tests designed to isolate the Human Factor, tricking the Daleks themselves into giving the Human Factor to test subject Daleks, and finally to administer the Dalek Factor to the Doctor himself, which he knew would only work on humans. (TV: The Evil of the Daleks) In a similar way, he got Donald Bruce to ally with him over Ramón Salamander, (TV: The Enemy of the World) pretended to go along with the Great Intelligence's brain transference operation in order to short-circuit the disembodied being, (TV: The Web of Fear) convinced the War Chief to regard him as an ally, (TV: The War Games) and persuaded Omega to spare the Third Doctor's life. (TV: The Three Doctors)

He was also a convincing actor, being able to masquerade as the Chameleons' Director without arousing suspicion, (TV: The Faceless Ones) and, against his will, also impersonated his physical double, Ramón Salamander, with a performance convincing enough to fool Jamie and Victoria. (TV: The Enemy of the World) He easily donned disguises without self-consciousness to age, gender, or dignity; he posed as a German physician, a washerwoman, and a wounded British soldier in Scotland, (TV: The Highlanders) and dressed as a strange, gypsy-like musician in Atlantis. (TV: The Underwater Menace)

Physically younger than his predecessor, the Doctor was able to outrun various pursuers, (TV: The Seeds of Death) and avoid weapon ammunition fired at him. (TV: The Invasion) He also learned the arts of Venusian aikido on Venus. (AUDIO: Year of the Drex Olympics)

He also possessed telepathic ability, including being able to use telepathy to show Zoe Heriot his previous adventure with the Daleks via mental projection, (TV: The Wheel in Space) but found the process tiring. (TV: The Dominators) The Master of the Land of Fiction had to trick him with his loyalty to Jamie and Zoe in order to gain partial control of his mind and will. (TV: The Mind Robber) He locked his mind in battle with the Great Intelligence and kept it occupied long enough for his friends to act against it. (TV: The Abominable Snowmen) Although the Androgum Chessene could read minds, she could not read the Doctor's, even when he was drugged and helpless. (TV: The Two Doctors)

He was also shown to be adept with at least a basic level of hypnosis, having used it on Victoria to break the programming implanted by the Great Intelligence in Tibet, and on Songsten in order to extract information regarding the Intelligence's scheme, (TV: The Abominable Snowmen) and could reverse the hypnotism of. (PROSE: The Dark Path) The Doctor later put Vana into a trance following the mental assault inflicted on her by the Krotons. (TV: The Krotons) He could even use hypnotism to induce amnesia. (PROSE: The Roundheads)

The Doctor could instinctively keep track of time, even without a way to measure its passing, (PROSE: The Murder Game) and could donate indefinitely large amounts of blood. (PROSE: Heart of TARDIS)

Appearance
The Second Doctor resembled a short man in his early forties. (TV: The Tenth Planet, The Power of the Daleks) He was physically identical to the dictator Ramón Salamander. (TV: The Enemy of the World)

He had blue eyes, (TV: The Three Doctors) though one account described his eyes as being "soft chestnut brown", (PROSE: Pluto) while another depicted them as bright green. (COMIC: Bazaar Adventures) A fourth account claimed his eyes appeared to change colour several times, alternating between blue, grey, and green. (PROSE: Invasion of the Cat-People)

By the time of his exile on Earth, the Doctor had the mark of Blenhim on his chest due to an encounter with the alien race. (COMIC: The Mark of Terror)

Liz Shaw told her mother that the Doctor resembled a "geography teacher" when he first encountered UNIT. (AUDIO: The Last Post) Polly Wright described him as looking like "an unmade bed" to Jamie, (PROSE: The Nameless City) and "a bit sartorially challenged" to the Brigadier. (AUDIO: The Three Companions) Madame Razetskia described the Second Doctor as a "funny little clown", (PROSE: Endgame) while William Blake saw him as "a middle aged man with a mop of black hair" when Legion took on the appearance of the Second Doctor. (PROSE: The Pit)

Samantha Briggs described the Second Doctor as "a short man, with a mournful face and dishevelled clothing." She also noted that he had a "blurred" English accent, which defied description, and seemed to be extremely knowledgeable on a wide variety of subjects. (PROSE: Who Killed Kennedy)

The First Doctor called his second incarnation "a clown" due to his scruffy appearance, (TV: The Three Doctors) whilst the Third Doctor labelled him a "scarecrow", (TV: The Five Doctors) and the Fifth Doctor described him as a "hobo". (PROSE: Five Card Draw) Being a body that was was "not what [he] would have wished for," (AUDIO: The Power of the Daleks) the Fourth Doctor described him as having "a moptop and chequed trousers". (AUDIO: The Fate of Krelos) The Eighth Doctor recalled his second incarnation as being "a comic little man with a flute". (PROSE: Escape Velocity) The Twelfth Doctor described him as "[an] annoying bumbler" with "big trousers". (PROSE: Twice Upon a Time)

When Affinity took on the Second Doctor's appearance, the Twelfth Doctor noted that his second incarnation was "a rather scruffy gentleman, [with] dark, unruly hair" and was "clad in a jacket that seemed several sizes too big and to have been slept in." (PROSE: Silhouette)

Hair and grooming
The Second Doctor had longish, rumpled black hair, (TV: The Tenth Planet) though, after going on a stressful mission for the Time Lords, (PROSE: World Game) his hair briefly turned grey. (TV: The Two Doctors)

Polly compared his hairstyle to those worn by the Beatles, (AUDIO: The Three Companions) as did John Benton, (AUDIO: The Hexford Invasion) Isobel Watkins, (PROSE: Who Killed Kennedy) Ace, (AUDIO: The Light at the End) and Jo Grant. (AUDIO: The Defectors)

Main attire
The Second Doctor dressed similarly to his previous incarnation, though in far more clustered fashion; His trousers were clownishly large and his bow tie was often crooked and used to secure his shirt collar. (TV: The Power of the Daleks)

He wore a battered old frock coat many sizes too large, which added to his clownish demeanour, (TV: The Power of the Daleks) but demonstrated its usefulness as a secret arsenal of tools, gadgets, food, and seemingly frivolous objects; he carried the TARDIS' Time Vector Generator inside a pocket in his inner lining without difficulty, (TV: The Wheel in Space) and had a magnet hidden in a pocket sewn behind his outer breast pocket. (TV: The Invasion) The Doctor often kept a plain handkerchief in the coat's breast pocket, (TV: The Highlanders) though occasionally switched it for a stylised one. (TV: The Three Doctors, The Two Doctors)

Under his frock coat, he wore a plain shirt with a blue polka-dotted bow tie. (TV: The Power of the Daleks) His shirt colours varied from a dull or bright blue. (TV: The Power of the Daleks, The Three Doctors) He wore one dark blue sock and another with a purple cartoon dinosaur on it. (PROSE: The Colony of Lies) He also wore black ankle boots with either brown-themed baggy plaid trousers, (TV: The Power of the Daleks) large plain grey pants, (TV: The Three Doctors) or grey-themed tartan trousers (TV: The Two Doctors) Occasionally, he would wear a waistcoat. (PROSE: Daleks Invade Zaos, Golem)

When in colder environments, the Doctor would wear a cloak, (TV: The Highlanders, The Underwater Menace, The Tomb of the Cybermen) or an oversized fur coat. (TV: The Abominable Snowmen, The Ice Warriors, The Five Doctors, The Name of the Doctor)

The Fourth Doctor though that his second incarnation's attire was "unacceptable" for a Time Lord. (AUDIO: The Power of the Daleks)

The Second Doctor expressed a liking for hats, stating that he "would like a hat like that" when he spotted new headgear. (TV: The Power of the Daleks, The Highlanders; PROSE: A Comedy of Terrors) His most prominent hat was a stovepipe hat, (TV: The Power of the Daleks, The Underwater Menace) but he also wore a hat and a British Army tricorn while in Scotland. (TV: The Highlanders)

Other costumes
While in Paris on a mission for the Celestial Intervention Agency, the Doctor wore white breeches, a neatly-tailored long-tailed black coat with a frilled shirt and cravat, gleaming black boots and a short travelling cloak, and wore a Bregeut watch. Before visiting the palace, he changed into a black coat, black breeches, and a frilly white shirt with an elaborate black cravat.

For the Battle of Waterloo, the Doctor donned black breeches, a black evening coat, a frilled white shirt, and a white waistcoat. (PROSE: World Game)

When his first incarnation was placed on trial in 1963 London as a result of killing a werewolf with a silver bullet, the Second Doctor dressed in an ill-fitting suit. (PROSE: The Juror's Story)

Behind the scenes

 * Rupert Davies, Valentine Dyall, Michael Hordern and Brian Blessed were all approached for the role of the Second Doctor. All declined, as they didn't want to commit to a long-running series.
 * Matt Smith, in preparation for his role as the Eleventh Doctor, watched the Troughton serial The Tomb of the Cybermen, and fell in love with it. He describes Troughton as "rather wonderful" and as being his favourite Doctor. Smith's costume and mannerisms are reminiscent of Troughton's.
 * Almost half of the episodes from the Second Doctor's era have been lost, leaving only seven of Patrick Troughton's 21 TV stories still fully intact (excluding his appearances in multi-Doctor specials). Five further incomplete stories have been released commercially, with specially-created material to bridge the missing episodes. Surviving "orphan" episodes and footage have been released on the Lost in Time DVD collection.
 * The Second Doctor was the first incarnation to directly work with four of his other selves on television, though that turned out to be a number also attained by the Fifth Doctor by virtue of Time Crash. If one includes a story this wiki generally doesn't — Dimensions in Time — then it could be said that the Third and Sixth Doctors were on the "four-timer" list, as well. However, there was no actual "interaction" between Doctors in Dimensions.
 * Until Time Crash, the Second Doctor was the only incarnation to appear in all televised multi-Doctor stories. As of 2013, Troughton holds the record for working with the highest number of other incarnations, having directly interacted with four other Doctors: the First, Third, Fifth, and Sixth Doctors. Taking into account all performed media, however, the record-holder is Peter Davison. His appearances on audio with the Sixth, Seventh, and Eighth Doctors add to his totals from The Five Doctors and Time Crash, to give a grand total of eight other Doctors.
 * The Second Doctor was the first incarnation to have his face integrated into the Doctor Who title sequence, beginning with The Macra Terror.
 * The Second Doctor is the only incarnation who was forced to regenerate, though the regeneration isn't seen in The War Games, and was confirmed he didn't regenerate until The Night Walkers, the only story to actually show the Second Doctor's regeneration properly.
 * Uniquely the Second Doctor is the only incarnation who didn't regenerate at the end of his last regular appearance, instead his regeneration was shown in the comic story The Night Walkers, also making the Second Doctor the only incarnation to regenerate outside of the television series.
 * The Second Doctor was the only incarnation to emerge from his regeneration with a different set of clothes, as opposed to future incarnations who would have to find a new pair of clothes after changing out of the clothes worn by their previous incarnation.
 * The role of the Second Doctor in the Big Finish plays has been portrayed by close friend and fellow Who actor Frazer Hines, as Patrick Troughton had died 12 years prior to the company's first Who audio.
