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.

Foreshadowing
After his struggle with the Celestial Toymaker, the Doctor began to feel he was nearing the end of his first life, becoming increasingly unwell, (PROSE: The Man in the Velvet Mask) and was afraid of the change. (PROSE: Ten Little Aliens)

Post-regeneration
After having the "stuffing knocked out of him" fighting the Cybermen in Antarctica in December 1986, (COMIC: Blood and Ice) 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 it 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 took the Doctor, Ben and Polly to 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. He was sceptical when the Dalek claimed to be the colony's servant and desperately tried to convince the humans that the Daleks 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. Despite knowing it was a losing battle, the Doctor, Ben and Polly 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 killer of the examiner. (TV: The Power of the Daleks)

Immediately after leaving Vulcan, he, 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)

Shaken after watching the deaths of the rebels, the Doctor and his companions shut down the machines controlling the Masters' life processes. (COMIC: The Dream Masters)

The Doctor, Ben and Polly then visited Trefus, where they discovered 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 tested them to prove their innocence by swimming in a lake filled with crocodiles, which they won and were accepted into society. (COMIC: The Tests of Trefus)

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.

He encountered the Vist and theorised that they saw time like humans saw space.

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)

The group 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. When he said Jamie wasn't for sale, the Voraxx members followed them.

The Voraxx 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. The slaves took over the ship, forcing the slavers to leave. As the trio teleported back to the shop, the Doctor was shocked to find his companions missing, having been captured by Adam Mitchell. (COMIC: Bazaar Adventures)

When Jamie and Zoe were imprisoned in an alien prison disguised as an English country home, the Doctor allied himself with gentlemen thief Lucas Seyton. The pair infiltrated the prison and, after being reunited with his friends, the Doctor closed the prison down. (PROSE: Fallen Angel)

They landed on Space Station Artemis a few decades after Zoe's time. He got worried when Zoe noticed that the the the space station was a bioweapons facility. When the spaceship broke up he got Jamie to spacewalk and save Zoe from the void. (AUDIO: Second Chances)

He was very interested in the Edge after he discovered that it was a scientific research facility. When he asked to tour the labs he was given a test by Sebastian, as well as being offered some mind altering drugs, the drug Acuman, to help him. Provost Curtis asked him to join his crew permanently but he didn't want to. Jamie stopped Curtis from taking him, but the Doctor had to quickly escape as the Edge was now 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)

Fleeing Gallifrey, the Doctor committed suicide and regenerated into a female incarnation. The Doctor was nearly executed, but instead the events leading to his suicide were erased. While he remembered escaping and regenerating, in the new timeline, he did not actually do so.

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)

Working for the CIA
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 temporarily grey. 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)

Whilst hunting a troubled woman who had the ability to make others feel her pain and loneliness, the Doctor met an American teenager called Nanci Cruz, who helped him to stop the woman. (PROSE: Mother's Little Helper)

The Doctor and Jamie then travelled to Helicon Prime to relax, but whilst there, there were several murders. He decided to investigate the who was to blame and discovered that it was the murderer was the famous singer Mindy Voir. (AUDIO: Helicon Prime) They later travelled to Earth in 54,010 and rescued a tribe of Stone Age humans from a bio-dome. (PROSE: All of Beyond)

As his predecessor had done before him, the Doctor took Jamie back in time to kill a baby destined to grow up into a dictator who would doom the Earth. However, the Doctor was unable to go through with the act, and left. (PROSE: Categorical Imperative)

After Jamie was returned to his own time by the CIA, (AUDIO: Helicon Prime) this time keeping his memory using a mind-trick the Doctor taught him, (COMIC: The World Shapers) the Doctor had an encounter with the Terrible Zodin, (TV: The Five Doctors) and then acted as a jury member of the First Doctor's trial. (PROSE: The Juror's Story)

The Doctor joined forces with a gang of teenage outcasts to stop the awakening of a golem, (PROSE: Golem) and teamed up with all of his other incarnations to save Gallifrey from destruction at the end of the Last Great Time War, but lost all memory of the event due to the timelines not being synchronised. (TV: The Day of the Doctor)

The Doctor defeated the Blenhims, (COMIC: The Mark of Terror) and visited Clio on her birthday to give her a recorder as a present. (PROSE: The Glass Princess) Escaping from the butterflies of Phlok, the Doctor met the Guerners on Rimba, (PROSE: The Sleeping Beast) and spent decades learning the psychic techniques of the Mind Monks of Darron. (PROSE: The Quantum Archangel)

The Doctor attended the funeral of Alistair Gordon Lethbridge-Stewart, as did all of his other incarnations. (PROSE: The Gift, Shroud of Sorrow)

The Doctor attended a UNIT reunion party, where he and the Brigadier were kidnapped by Borusa and taken to the Death Zone. The two escaped from a squad of Cybermen, encounter a Yeti and faced illusions of Jamie and Zoe. In the Dark Tower, the Doctor met his first, third and fifth incarnation, their companions and. After Borusa was turned to stone by Rassilon, the Doctor was returned to his timezone. (TV: The Five Doctors)

During a brief trip in the TARDIS with the Brigadier, the Doctor was trapped in the event horizon of a black hole, (AUDIO: The Three Companions) and, still wearing his fur coat, had an adventure in an America park, where he briefly crossed paths with the Eighth Doctor and a version of Clara Oswald. (TV: The Name of the Doctor)

The Doctor was trapped in the Determinant by, along with his six other incarnations, but was saved when the Graak defeated the Master, and sacrificed it's life force to liberate the trapped Doctors. (GAME: Destiny of the Doctors)

The Doctor attempted to form a band with his first, third and fourth incarnations, but creative differences, and the fact that they all wanted to play the drums, broke them up. (COMIC: Day of the Tune)

The Doctor helped Jovain Pallis investigate a murder on human colony on Mars, only to discover that Jovain was the murderer, (PROSE: Dust) gave a librarian a purpose in life, (PROSE: Pass It On) and went undercover at a film production which featured the Cybermen. (PROSE: Scientific Adviser)

Hiding in luxury
Unable to hide behind CIA protection, the Doctor's sentence of exile to Earth was enforced, (COMIC: Action in Exile) although he was able to escape before the Time Lords could enforce a regeneration. (COMIC: The Night Walkers) 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 make him think he had been executed at his trial. (AUDIO: Legend of the Cybermen, Stage Fright) The TARDIS travelled to an English field, where it was found, along with the newly regenerated Doctor, by UNIT. (TV: Spearhead from Space)

Post-mortem
In the Doctor's dream garden, the Second Doctor planted Forget-me-nots, in memory of Jamie and Zoe. (PROSE: Into the Silent Land)

When under attack by an space amoeba, the Fourth Doctor briefly turned back into his second incarnation. (COMIC: Timeslip)

When the Tenth Doctor was confronted by Es'Cartrss within the TARDIS' Matrix, he summoned the Second Doctor, among his other past incarnations, to use their united memories and willpower to take back control of the Matrix. (COMIC: The Forgotten)

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)

Undated adventures

 * Either due to 's deceptions, (AUDIO: The Black Hole) or acting under the CIA's authority, (PROSE: World Game) the Doctor and Jamie went to persuade Joinson Dastari to stop his experiments with time at the Space Station Camera, but Dastari and his mutated 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 Seville from survivors, such as Jamie, who escaped the massacre and reported everything to the sixth incarnation of the Doctor and Peri when they discovered him. The combined efforts of the four put a stop to the dangerous plans, but not before the Second Doctor was briefly turned into an Androgum. (TV: The Two Doctors)
 * The Second Doctor saw the musical Hamilton and had his picture taken by Alice Obiefune when he was near the Tenth and Eleventh Doctors. (COMIC: The Long Con)
 * River Song was offered "this cool place on Telos" by the Second Doctor, but according to her diary she "saw right through that (and I hope he chokes on that recorder.)" She had his memory wiped with mnemosine recall-wipe vapour so the timeline would remain intact. (GAME: The Eternity Clock)
 * The Second Doctor gave a few lines of credit to Snorglarr on Vortis, to repay a debt a future incarnation owed Snorglarr. (COMIC: The Rise and Fall)

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

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)

Personality
The second incarnation was a complete change of pace from his predecessor - whimsical, somewhat buffoonish, yet still witty. He was no longer a grandfather figure, but rather more of a favourite uncle. Indeed, the slow transition of the first incarnation from a reluctant travelling companion to a more kindly compatriot was completed here, as the second incarnation very much enjoyed embroiling himself in adventures with his assistants. Despite his bluster and tendency to panic when events got out of control, the Second 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)

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)

He 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) Although he was always in trouble, he loved peace and quiet and was as surprised and frightened of alien menaces as those who faced them with him. However, 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) 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)

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) 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)

Paradoxically, he had a deep streak of ruthlessness when needed, as he wired the Cyber-Tombs doors to fatally electrocute anyone trying to open them, (TV: The Tomb of the Cybermen) reacted unfazed to Salamander's fate, (TV: The Enemy of the World) 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)

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)

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)

The Sixth Doctor considered his second incarnation to be an "antediluvian fogey" for apparently being captured by the Sontarans. (TV: The Two 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 tantrum until he was restrained. (TV: The Two Doctors)

Zoe Heriot considered the Second Doctor to be a "lovely little man", who was "such fun to be with." (PROSE: One Small Step...) On another occasion, she described him as "old, clever and kind." (AUDIO: The Five Dimensional Man)

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 he was shot and executed by the Time Lords' animated scarecrows, the Doctor used his dying breath to reassure Farmer Hogan, who was on the verge of a nervous breakdown from 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) 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 phrase 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)

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)

The second incarnation 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) or play a tune with a hidden message.

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)

Other 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)

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 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 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) The Doctor later put Vana into a trance following the mental assault inflicted by the Krotons. (TV: The Krotons)

Physically younger than his predecessor, the Second Doctor was able to outrun various pursuers, (TV: The Seeds of Death) and avoid weapon ammunition fired at him. (TV: The Invasion)

Though the Second Doctor learned the arts of Venusian aikido on Venus, he never actually used it. (AUDIO: Voyage to Venus)

The Doctor was also a convincing actor, being able to masquerade as the Chameleons' Director without arousing suspicion, (TV: The Faceless Ones) and, against his will, he also impersonated his physical double, Ramón Salamander, with a performance convincing enough to fool Jamie and Victoria. (TV: The Enemy of the World)

Appearance
The Second Doctor resembled a shortish man in his early forties. (TV: The Tenth Planet, The Power of the Daleks)

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 third 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 Second Doctor had the mark of Blenhim on his chest. (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)

The First Doctor called him "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)

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)

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 also 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)

Clothing
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 demeanor, (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 handkerchief in the coat's breast pocket. (TV: The Highlanders)

Under his frock coat, he wore a plain shirt with a blue bow tie. (TV: The Power of the Daleks) His shirt colours varied from plain white to a bright or dull blue. (TV: The Power of the Daleks, The Three Doctors, The Five Doctors) He also wore black ankle boots with either brown-themed baggy plaid trousers, (TV: The Power of the Daleks) 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)

He also 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) His most prominent hat was a stovepipe hat, (TV: The Power of the Daleks, The Underwater Menace) but he also wore a and a British Army  while in Scotland. (TV: The Highlanders)

The Brilliant Book 2011
According to The Brilliant Book 2011 (a non-narrative based book), the Second Doctor met Winston Churchill in 1882, giving him lessons in Latin, including how to address a table in Latin.

Other matters

 * 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.
 * Unlike future Doctors after himself, 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.
