->''Splendid fellows -- all of you.''
-->--'''TheBrigadier''', "[[Recap/DoctorWho20thASTheFiveDoctors The Five Doctors]]"

A [[SufficientlyAdvancedAlien Time Lord]] from the planet Gallifrey, the Doctor ([[OnlyKnownByTheirNickname real name unknown]]) is the main character of [[Series/DoctorWho this long-running show]]. Like all Time Lords, he has a life span measured in centuries, some degree of psychic ability, and the ability to regenerate when near death. Unlike other Time Lords, he became terrified by the Gallifreyan way of life when he was young, stole an antique TARDIS, skipped town and "never stopped running".

The Doctor remains the same ''person'' throughout his lives, but different incarnations have different personalities. {{Showrunner}}s tend to cast each Doctor as a subversion of the previous one in both attitude and appearance. Hence, the original stubborn old grandfatherly git became clownish, suave, loopy, kind, peremptory, manipulative, romantic, weary, harsh, hyperactive, and adorkable. After the show's return in 2005, it's added a bit more CharacterDevelopment than the classic series.

[[foldercontrol]]

[[folder:All Doctors]]
* AdmiringTheAbomination: Many Doctors do this at least once in a while, but it's a particular specialty of Ten's.
* AlienNonInterferenceClause: Downplayed. He tries to stick to "meet new people, stop threat of the week, then fly off saying IWasJustPassingThrough" - and disapproves of the Monk trying to "improve" history.
** This strategy does come back and bite him in the butt a few times, due to him introducing instability and change, but not sticking around to see the fallout. Ten changed Harriet Jones, (former) Prime Minister's fate, which allowed Harold Saxon to set up.
* AllergicToRoutine: It varies per Doctor. Five was quite okay with spending long periods of time just relaxing; Eleven gets intensely annoyed after about a minute.
* [[AlwaysSaveTheGirl Always Save The Companion]]: So far, four incarnations (Three, Five, Nine and Ten) have died trading their life for their companion's.
* AmbiguouslyBi: He will flirt with his male and female companions and will mouth kiss just about anybody. The HoYay between the Ninth Doctor and Jack and the Eleventh Doctor and Rory are prime examples.
* AntiHero: Regardless of the incarnation, he's an arrogant and vain old man who tries to do good in spite of himself.
* AttentionDeficitOohShiny: To varying degrees in every one of his incarnations. Exactly how extreme it is varies considerably, with Four, Six and Eleven being particularly severe cases. But as a rule the Doctor can rarely stand to stay in one place for very long and simply cannot focus on long-term projects. Despite the fact that the TARDIS obviously needed some maintenance, the only time the Doctor really put serious effort into it was in his Third incarnation, when the Time Lords stranded him on Earth. Even then he kept himself amused running around with UNIT.
* AwesomeAnachronisticApparel: The Doctor seems to intentionally prefer old-fashioned clothes, especially waistcoats which he's worn in several incarnations. Of course, as a time-traveler, ''everything'' is anachronistic apparel to him.
** Even the Ninth Doctor, who outwardly appeared to be wearing the most modern outfit, was [[OlderThanTheyThink actually]] wearing a Kriegsmarine Captain's Jacket from UsefulNotes/WorldWarII, a similar look to the War Doctor's brown leather overcoat.
* {{Badass}}: All regenerations of the Doctor are both fearless and completely over the top.
* BadassGrandpa: He's already an old man when we first meet him, and a grandfather to boot.
* BadassPacifist: To an extent. The Doctor usually tries to use his wits to solve problems rather than violence.
* BavarianFireDrill: After the introduction of the psychic paper in "The End of the World", the ImpersonationGambit is used more often.
* BeenThereShapedHistory: The Doctor's met nearly every famous historical character, at nearly every important event in history, and generally has an anecdote or two about them. Churchill has his phone number.
* BenchedHero: Three, Five, Ten, and Twelve's regenerations put them out action for much of it. Seven was immediately hypnotized to do the Rani's bidding, so honorable mention there. Two, Four, Six, Eight and Eleven hit the ground running.
* BerserkButton: Don't hurt or kidnap his companions. Or try to destroy the Earth; we're his favourite aliens. Or enslave people, ''especially'' [[PapaWolf kids]]. The usually calm Doctor will end you.
* BewareTheNiceOnes: The Doctor is, fundamentally, a good person... who will blow up enemies, spaceships and entire planets if it saves the day.
* BewareTheSillyOnes: Even the more serious incarnations have their {{Adorkable}} moments, often in the face of extreme danger. Two, Four, Ten and Eleven are particular masters of this trope.
* BigDamnHeroes: All [[spoiler:thirteen]] of them work together to save the day in "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]".
* BigGood: His name inspires hope in all that is good and terror in all that is evil. Where he goes, freedom (and explosions) quickly follow. Frequently acknowledged as this, by friends ''and'' [[WorthyOpponent enemies]] alike.
--> '''The Master''': A cosmos without the Doctor scarcely bears thinking about.
* BittersweetEnding: The regenerations from one Doctor to the next. The Doctor is going to be fine, but he'll never be the same.
* BizarreAlienBiology: As a Gallifreyan [[BioAugmentation Time Lord]], the Doctor can do weird things like counteract cyanide poisoning given a bunch of weird ingredients, absorb radiation and expel it through his foot or forgo the need to ''breathe'' for a few minutes, and can withstand massive amounts of electricity. Oh -- and he has two hearts. Not to mention that when he is close to death he can avoid it by essentially reassembling his body and regenerating into a new one, which changes his personality, quirks, likes and dislikes, though he essentially remains the same person.
* BornLucky: With a little help from the TARDIS.
* ABoyAndHisX: A Time Lord and his TARDIS. [[spoiler:Or, as she sees it, the TARDIS and her Time Lord.]]
* BreakTheCutie: Each new Doctor starts out reinvigorated and carefree. CharacterDevelopment sets in and the tone of the show grows darker until it's regeneration time.
* BunnyEarsLawyer: He never quite manages to pass as fully human (or whatever race he's impersonating). But he's probably more adept at whatever's happening than anyone else, even if it involves wearing a piece of celery or comically pulling eggs out of his mouth.
** The Doctor is still registered as a full-time UNIT staff member, despite clocking in approximately once per decade and generally avoiding work like the plague.
** He's also been Lord President of Gallifrey at least once, and managed to skip out on that too.
* ButNowIMustGo: The Doctor has a habit of bringing your world down around you and then vanishing prior to rebuilding. This was deconstructed in "Bad Wolf" and ''The Face Of Evil'' (albeit that one was due to NoodleIncident), though the Doctor didn't learn his lesson.
* CainAndAbel: The Abel to The Master's Cain. It's never been confirmed on the show that the two are actual brothers, and the Doctor denies in the revived series - although the Doctor isn't the most reliable source when it comes to his past. Even if they're not biologically related, the series makes it clear that they were as close as brothers growing up, so it still counts.
* CatchPhrase: "Of COURSE!"; "I'll explain...later." and of course, "Run!"
* TheChessmaster: Creator/NeilGaiman notes that the Ninth Doctor tires of having to explain himself, and would much rather lurk on the periphery and move people around from a distance. However, this trait is visible as far back as Troughton in "Tomb of the Cybermen." The lack of subtlety on the Doctor's part varies: Troughton shrinks into the scenery to hide, keeping himself unnoticed and underestimated. Tom Baker, on the other hand, hangs a bright neon "[[CheshireCatGrin I am lurking in the scenery waiting to pounce and make my move!]]" sign over his neck.
* ChronicHeroSyndrome: Distress signals always get the Doctor's attention.
--> '''Amy Pond''': So is this how it works, Doctor? You "[[BlatantLies never interfere]] in the affairs of other [[AlienNonInterferenceClause peoples or planets]]"... ''unless'' there's children crying?
--> '''Eleventh Doctor''': [[BigGood Yes]].
* CloudCuckooLander: All the incarnations of Doctor will at the very least have shades of this.
** One was prone to making humorous (and rather weird) observations.
** Two's was mostly a case of ObfuscatingStupidity, though he was genuinely a bit dotty at times.
** Three would frequently speak to the Master (a murderer who attempts to conquer the planet on a regular week-to-week basis) as though he were having a chat with a good friend, even during jail cell visits.
** Four was as manic as his hair, offered jelly babies to pretty much everyone, and tended towards behaving like he was on a sugar bender most of the time.
** Five wore a stick of celery on his lapel, and would often change his mind about where he wanted to go mid-stride and turn and dash in that direction without telling his companions.
** Six truly believed his coat was fashionable and was reality-defyingly blind about his own lack of tact and subtlety.
** Seven was daring and bold to the point that he [[Recap/DoctorWhoS26E1Battlefield casually walked between two men sword-fighting to the death, even tipping his hat as the two men stared at him in disbelief]].
** Eight was prone to making non sequitur observations in the middle of serious conversations and could be ridiculously LiteralMinded.
** The War Doctor seized a weapon amidst the violence and mayhem of the Time War [[MundaneMadeAwesome to write the words "No More" on a wall]].
** Nine believed being a tourist meant doing all sorts of crazy stuff you can do, just for the hell of it, and had a habit of generally ignoring Human customs.
** Ten would have random and over the top geeky fits over [[HumansAreSpecial how wonderful humans are]], sometimes randomly hugging them just for the hell of it.
** Eleven is obsessed with bow ties and fezzes, believing them to be fashionable, even after women have been willing to destroy the latter to prove otherwise. He'll also openly refer to himself as a madman.
** Twelve spends his very first moments rambling about the state of his kidneys, then proceeds to flirt with a Tyrannosaurus Rex in his nightclothes during his first episode.
* CoolOldGuy: Strictly speaking, all of them are chronologically, but some regenerations don't even resemble the part. However, some of the younger looking regenerations like Eleven do embrace the concept.
* DeadpanSnarker: The degree of deadpan and the preferred delivery method of it may vary, but you don't have to scratch any of the Doctors too hard to find the Grade A Snark contained within.
* DeathByOriginStory: Technically the regeneration of one Doctor into another is this, since the previous Doctor has to die for the new one to be born.
* DeathIsDramatic: Regeneration episodes themselves tend to be very melancholy in nature; see "Planet of the Spiders", "Logopolis", "Caves of Androzani", "Night of the Doctor", "The Parting of the Ways", "The End of Time" and "The Time of the Doctor".
* DefectorFromDecadence: The circumstances behind him leaving Gallifrey (other than a desire to see the world) are unclear, but he was always critical of the stagnation of Time Lord society.
* DeusExMachina: When you think about it from the perspective of a lot of the characters who only show up in one story, the Doctor himself is a Deus ex Machina. Think about it, these people are in the middle of a dangerous crisis, or in the early stages of one, and then out of nowhere, a strange blue box shows up. Then some guy and his companion(s) walk out and solve the whole damn problem.
** Subverted in Midnight. Those guys thought he was the cause of it.
* DissonantSerenity / TranquilFury: When sufficiently angered, the Doctor is quite capable of raining fire down on his enemies with a look of utmost calm.
* DistressedDude: He gets tied up, handcuffed and so on almost as often as the companions, if not more.
* DoesntLikeGuns: No version of the Doctor has been exactly gun-happy, though some accepted them [[BatmanGrabsAGun as a last resort]].
** One was seen with a gun once or twice, though he preferred to immediately give it back to whoever was trying to shove one into his hands.
** Two has held and handled guns quite a few times during his run, sometimes using them as convenient yet [[StealthPun empty]] threats. He didn't evince any obvious distaste for guns in general, but he never did actually fire one. He also built a heat ray and used it to great effect against Ice Warriors.
** Three would much rather karate chop a poor sucker than shoot him, though he did sometimes kill with a gun.
** Four would pick up a gun if the situation called for it, and rather enjoyed himself with the things. (His aim, however, left much to be desired.)
** Five actually blew away a couple of enemies, though only if there was no other option left.
** Subverted by Six, who was more willing to pick up a gun than the others would a Sonic Screwdriver. The best example of this is in "Attack Of The Cybermen". Six generally wasn't averse to murder.
** Seven would never use a gun himself, but didn't mind when others used similar weapons like rocket launchers or ballistic explosives if the situation demanded it.
** Eight used a gun several times. In his one televised adventure, he stole one from a police officer and used it to hold himself hostage. Other times, he simply refuses to acknowledge them as guns, [[InsaneTrollLogic because "I don't use guns."]]
** Subverted by the War Doctor, who was a warrior and soldier by nature, although the only moments we see him fire a gun on-screen are when he is using one [[MundaneMadeAwesome to write the words "No More" on a wall]], and when he blasts a Dalek who sees this writing.
** Nine held a gun twice: whether he would actually have shot is debatable. Then again, he also switched Jack Harkness' gun for a banana at one point. He also demanded information at gunpoint and, when his victim protested, said "I'm not gonna shoot you," and ''gave him the gun''. Then continued demanding information, which the victim ''gave him''.
** As far as Ten was concerned: Swords, explosives, pet robots with lasers, flooding rivers, taping over electronic villains, erupting volcanoes, electrocution through a piece of the TARDIS, [[FateWorseThanDeath Fates Worse Than Death]], throwing entire planets into black holes, fatally accurate satsumas and death by church organ? Perfectly legitimate methods of combat. Guns? '''NEVER'''. However, Ten did pick up a gun on his last day, when he realized that [[spoiler:the Time Lords were returning. And he pointed it at Rassilon.]] He ended up firing the gun, though [[spoiler: not at a person]].
** Eleven admits that he still "has a thing" against guns, but isn't quite as obsessed with avoiding them if using one can save lives. Early on, he used a gun to activate an [[BuffySpeak anti-gravity thingy]] when being chased by Weeping Angels. He also admits that he likes using River as a back-up gun wielder, since she doesn't share his hangups, and he realizes full well how hypocritical that is. When his BerserkButton gets pushed hard enough, he can go into a violent rage and become ''very'' willing to point a gun at someone's head -- a fact that genuinely terrifies him.
* DoomItYourself: The TARDIS ''does'' actually have a manual, but the Doctor rarely bothers to follow it. The Sixth Doctor dismisses its instructions even when it could save his life, while Eleven later claims to have thrown it into a supernova after it disagreed with him one time too many.
* DoomMagnet: It's actually a cross between being this... and, a dedicated follower of Doom care of the TARDIS plonking him neck deep in it. Either way: he arrives; trouble happens; trouble unhappens; he leaves. And, leaves an impression that often closely resembles a crater in the process of being built on or flattened out.
* TheDreaded: As the series progressed, it has became the norm that any villain who recognizes who this strange individual calling himself "Doctor" is immediately browns their trousers. A number of times the Doctor himself calls attention to his identity for that effect.
** This effect seems to be especially prevalent with the Daleks, [[BeyondTheImpossible who are supposed to be]] ''[[BeyondTheImpossible physically incapable of feeling any emotion]]'', [[BeyondTheImpossible fear included.]] [[Recap/DoctorWhoS33E1AsylumOfTheDaleks To put things into perspective]]: There are Daleks deemed -- by their own race of emotionless genocide fetishists -- [[UpToEleven too insane to control]]; they're too awesomely hateful to kill, so they're put into an asylum. Then there are a few Daleks deemed [[EveryoneHasStandards too insane]] to share a room with ''those'' Daleks; they're put into an intensive care room. ''They'' are the few who [[DrivenToMadness survived a fight with the Doctor]].
** Both Ten and Eleven weaponised the word "Run", and were able to turn entire armies around at the very mention of their name. This status comes back to bite Eleven ''hard'' in Series 6, where it's revealed that in the Gamma Forest, "Doctor" does not mean "Helper of the weak and sick" like on Earth, but "Warrior", due to his sheer badassery. The Doctor does not think this is a good thing, and the whole affair inspires him to wipe his "dreaded" status from the universe and start over again without all the baggage of being a known quantity feared and exalted in equal measure.
** The War Doctor. He comments on both the Tenth and Eleventh Doctors looking at him with nothing less than "utter dread".
* DrivesLikeCrazy: In River Song's second appearance, she teases that he deliberately shuts off the TARDIS's stabilizers and drives with the parking brake on. Word of Moffat has it that she was just joking, though.
** Four once managed to land just in time for a cliff to explode on top of him and his companion. Peri at one point complains that Six caused three electrical fires and a power failure, nearly collided with a storm of asteroids, got lost in the TARDIS corridors twice, wiped the memory banks of the flight computer, jettisoned three quarters of the storage hold [[ArsonMurderAndJaywalking and burned her cold dinner]]. Ten outright admits he failed the TARDIS driving test. (You can tell.)
** However, the TARDIS is meant to have six pilots, which explains why he's always running round the console and fiddling with seemingly random parts. When we do see six people piloting the TARDIS at once, they're able to do it smoothly without any prior training.
** In addition to the lack of pilots, it doesn't particularly help that the Doctor ''[[DoomItYourself refuses]]'' to follow the instruction manual either.
** It has been confirmed (by [[spoiler: the TARDIS herself]]) in the revival that many of the times the TARDIS made an unexpected stop or landed at the wrong time and place are due to the TARDIS itself taking the Doctor to where he needs to be.
* DyingAlone: The Seventh, Eighth, War and Tenth Doctors all regenerated alone (though given that the last two were in the TARDIS, they don't count as a full example).
* EccentricMentor: To many of his companions.
* EraSpecificPersonality: The Doctor changes personalities in every regeneration.
* EternalHero: He's always there to save the day, anywhere and anywhen he is needed.
** Though sometimes [[Series/TorchwoodChildrenOfEarth he]] [[Series/TorchwoodMiracleDay isn't]], a fact explicitly pointed out in the former incident.
* {{Expy}}: When the show began, the Doctor hovered somewhere between AntiHero and AntiVillain, and Creator/StevenMoffat described the first Doctor as a senile old man. At some point, the first story editor David Whitaker realized that since he had to carry the show, he needed to be more of a cut and dried hero. Who did they turn to? Franchise/SherlockHolmes. It becomes clear with Moffat penning versions of ''Series/DoctorWho'' and ''Series/{{Sherlock}}'', since both come across as [[InsufferableGenius Insufferable Geniuses]] who both tend to say "Shut up, I'm thinking." Companions in general tend to fit the [[TheWatson Watson]] role pretty well.
* FamedInStory: Erratically, since he tends to hop around space and time and is not actually ''universally'' known -- but happens on many occasions.
** It's later been revealed that countless races across the universe ''do'' get the word "Doctor" intrinsically ingrained in their languages due to him, denoting either a "Healer" or "Great Warrior".
** By "Dinosaurs on a Spaceship" and "The Angels Take Manhattan", the Doctor has taken to removing all traces of [[{{Unperson}} his identity]].
* FanOfThePast: The Doctor is rather fond of Earth history.
* TheFettered: Despite being a self-proclaimed "madman with a box" who thinks keep-out-signs are for other people, he is very much this. [[AGodAmI Bad things happen]] when he starts breaking his personal rules.
-->''"Good men don't need rules. Now is not the time to find out why I have so many."''
** TheUnfettered: The [[FutureMeScaresMe Valeyard]], the [[AGodAmI Time Lord Victorious]] and [[spoiler: the [[{{UnPerson}} War Doctor]]]] can attest to that.
* FigureItOutYourself: He invokes the "changing the future" excuse.
* {{Flanderization}}: Every incarnation of the Doctor has gone through this to one extent or another, where certain quirks and personality traits seem to become more magnified the longer any one actor stays in the role.
** However sometimes they go through reverse Flanderization. The First Doctor became less stubborn and bad-tempered, and Six mellows out in Season 23, and more in Big Finish.
* [[spoiler: ForegoneConclusion: As revealed in "The Name of The Doctor", the ultimate fate of the Doctor is to die defeating an army at the battle at Trenzalore and have [[NegativeSpaceWedgie his remains]] entombed within the TARDIS. The Eleventh Doctor has apparently been aware of this for some time and refers to it as the one place he must ''never'' go]].
--> '''Clara''': [[spoiler: How can you have a grave?]]
--> '''Doctor''': [[spoiler: Because we all do, somewhere out there in the future, waiting for us]].
** [[spoiler: ScrewDestiny: Although the Tenth Doctor invokes this in "The Day of the Doctor", suggesting to Eleven that they could always try to change history to prevent their death at Trenzalore. Whilst Eleven is dying of extreme old age in "Time of the Doctor", the Time Lords use the cracks in the universe to grant him [[PetTheDog a new]] regeneration cycle and change his future]].
* FutureMeScaresMe / IHatePastMe: Tends to come up whenever [[MyFutureSelfAndMe interacting]] with his past or future incarnations.
** Taken to its extreme with the War Doctor, whom the Ninth, Tenth and Eleventh refused to admit even existed. The War Doctor, for his part, wasn't exactly impressed with Ten and Eleven either (at first).
* GeniusSweetTooth: Four loved Jelly Babies; Eleven preferred Jammie Dodgers.
* GentlemanAdventurer: Even once he starts to think of fighting the bad guys as a job, his main objective has always been to see as much of the universe as he can.
* AGodAmI: An immortal, omniscient alien with a time machine? ....Just get down on your knees and pray that he's never, ever in this mood around you.
* AGodIAmNot: His usual mode. He usually doesn't expect people to recognise him, let alone view him as a hero or (horrors!) see him as a being of nigh-invincible power; he's just someone who happened to be passing by who could and did help.
--> '''Ninth Doctor''': Don't worship me, I'd make a very bad god. Wouldn't get a day off for starters.
* GoToAlias: "John Smith", as well as several non-English variations on the word "who". The First Doctor once introduced himself as [[Film/TheCabinetOfDrCaligari Dr. Caligari]] and the Tenth Doctor used former companion Jamie [=McCrimmon=]'s name while pretending to be Scottish.
* GuileHero: Almost every incarnation of the Doctor prefers to use brains over brawn.
* HeadbuttingHeroes: With UNIT, people [[DoesNotLikeGuns who use guns]] and even with ''[[MyFutureSelfAndMe himself]]'' on occasion.
* TheHero: Only lacking trait is that he's not the JackOfAllStats.
* HeroesLoveDogs: Tin ones, in particular. Ten and Eleven still have nostalgia for K-9 and other robot dogs.
* HumanAliens: Though Ten and Eleven have argued humans are Time Lord aliens.
--> '''Amy''': You look human.\\
'''Eleven''': No; ''you'' look ''Time Lord''. ''We'' were first.
* HumanOutsideAlienInside: Despite looking human (or the reverse, whichever), the Doctor and his race are completely different down to an anatomical and biochemical level. Just detecting his two hearts is enough to convince most human(oid)s of what he is.
* HumbleHero: He's not modest, but he's essentially humble - might seem odd, but it's true. Though he shows pride over his own brilliance and abilities, he doesn't consider himself special, he'd just as soon leave any credit for what he does to someone else, is very aware the universe doesn't revolve around him and doesn't think it should, has dismissed any offers of power to him with some variation on "I wouldn't be very good at it", and can't seem to see that he's powerful enough that whole races devoted to the subjugation of the universe have banded together to try to destroy him.
* IconicItem: The Sonic Screwdriver and the TARDIS, of course. From 2005, the psychic paper.
* ImmortalImmaturity: There's no point in being grown-up if you can't be childish ''sometimes''.
* ImmortalityHurts: It would seem that regeneration never gets any less painful or disorienting. Each one is a miniature "death", of sorts, as the Doctor's brain is rewired with a new personality.
-->"It's [[{{Understatement}} a bit dodgy]], this process."
* IndyPloy: Combines with XanatosSpeedChess.
* InexplicablyAwesome: The Doctor is, quite frankly, oddball even for a Time Lord.
* InHarmsWay: Nothing keeps the Doctor from adventure.
* TheInsomniac: As has been established since the early days of the series, the Doctor needs very little sleep. The mini-episodes "Night And The Doctor" offer a glimpse into the things he gets up to when his companions are asleep.
* JumpedAtTheCall: He didn't just jump, he stole a TARDIS and went looking for it. [[spoiler: [[Recap/DoctorWhoS32E4TheDoctorsWife Or did she steal him?]]]]
* KindheartedCatLover: A few incarnations of the Doctor ''have'' shown a fondness for cats, particularly Six, Nine, and Ten (though Ten was initially wary of them).
--> '''Ten''': No, I'm not really a cat person. Once you've been threatened by one in a nun's wimple, kind of takes the joy out of it.
* KlingonsLoveShakespeare: The Doctor loves a SpotOfTea and (depending on the incarnation) sweets like jelly babies or jammy dodgers.
* KnightErrant: In theory the Doctor is just a traveler, usually not actively looking for wrongs to right. But he pretty much expects to find people to help wherever he goes and embraces the role of hero. There's usually a fair amount of damsel-rescuing too, considering one of the chief roles of companion is 'get into trouble'.
* KnightInSourArmour: So far, the only Doctor who's been consistently ''genuinely'' happy with being the dashing hero was Eight, and that's only because we saw a grand total of one adventure.
* LargeHam: Comes with the WorldOfHam the series is set in. All Doctors are hammy in their own way, some considerably more than others.
* TheLastDJ / RebelliousRebel: In the Classic Series, he was often this to the rest of the Time Lords.
* LikeAnOldMarriedCouple: With the TARDIS. [[spoiler: Because they totally are.]] And with other regenerations of himself: very few of them actually get along, and Two and Three in particular spend every moment bickering.
* LimitedWardrobe: The first four Doctors, as well as the Seventh, usually based their outfits around variations on a theme, though the Fifth and Sixth Doctors played the trope straight with completely unchanging apparel. The Eighth Doctor only had one adventure, so the wardrobe was limited to that story. (He's moved on to more modern clothing as of late 2012 in Creator/BigFinish.) The Ninth, Tenth and Eleventh Doctors return to the original method, with certain items (the leather jacket, trainers, and tweed jacket with bowtie respectively) typically remaining in place.
** As a side-note, the Fifth and Sixth Doctors did get to change their outfits once or twice during their run for an episode or two. For the Fifth, it was disguises and costuming. The Sixth had variations, including a light vest that almost didn't melt one's eyes. Still, their wardrobes mostly went unchanged during their tenure.
** The colour of the Eleventh Doctor's bowtie in series 5 changed depending if the story is set in the present or past (blue), or if it's in the future (red). Series six saw the blue change to a pair of custom ties, and once Clara came along we got a number of ties usually in purples. His braces/suspenders usually match his bowtie, as well.
** Due to cold weather while shooting episodes, Eleven ended up wearing a much longer and heavier jacket for a few episodes.
*** After changing companions Eleven swapped out the tweed jacket for a purple frock coat, and waist coat.
** Nine did [[ChangedMyJumper make some very very very minor efforts to blend in]] but you'd not really notice.
** Ironically, the TARDIS has an absolutely huge wardrobe. Of course, the Doctor can be very slow to pick up hints he particularly [[ObliviousToHints doesn't want to get]], so if this is [[FridgeBrilliance one of her hints]] about his taste in fashion, he's probably ignoring it like [[FailedASpotCheck the notice on the door]].
* LivingForeverIsAwesome: The classic Doctors very much enjoy their incredibly long life span. One, for instance, stole the TARDIS because he wanted to see everything and knew he would have the time to do so. (In Two's last serial and periodically since, it's implied he was running away from something very bad.) [[BreakTheCutie Then the Last Great Time War happened]]: The Doctor was never the same again and this trope became part of a StepfordSmiler mask.
* LossOfIdentity: Every regeneration must deal with this and discover his new persona. How much it affects him seems to vary: the Seventh Doctor called it a "purely perceptual" change, while the Third and Tenth considered it death. It also tends to vary depending on which side of the regeneration he is; the Third and Tenth Doctors expressed these sentiments just ''before'' regenerating, while the Seventh expressed his sentiment ''after''.
* MadScientist: Any time the Doctor starts tinkering or building gadgets, he veers into this territory.
* MagneticHero: Everything gravitates towards him.
* MasterOfUnlocking: And ''locking'', at that, thanks to the sonic screwdriver.
* MrExposition: Since he typically knows more than anyone else does.
* MrFixit: Even once jokingly called himself "the maintenance man of the universe".
* MrSmith: Almost every time the Doctor needs a name, he simply uses the bland pseudonym "John Smith." This is even his official legal name during his time stranded on Earth working for U. N. I. T.
* MysteriousPast: The franchise has been around for fifty years and we still do not know the Doctor's real name or why he no longer uses it.
** We didn't learn the name of the Doctor's species until the end of Patrick Troughton's run and we didn't learn the name of his home planet until Jon Pertwee took the reins.
** We know he once had a family and even children, but "lost them long ago". Given how we never get any indication that (apart from Susan) they're still alive even ''before'' the Time War, it's possible this was one of the reasons the First Doctor so readily JumpedAtTheCall.
* NamesToRunAwayFromReallyFast: "Doctor" doesn't always mean "healer" anymore in cultures he's visited.
* NeverAcceptedInHisHomeTown: The Doctor has never gotten on particularly well with most of his fellow Time Lords. Even though he's saved Gallifrey multiple times, the High Council tends to view him as an embarrassment. The Time War only made their relationship worse.
* NinjaPirateZombieRobot: The Doctor is a psychic alien time-traveling slider.
* NoNameGiven[=/=]EveryoneCallsHimBarkeep: The Doctor ''does'' have a name, but it's never been revealed.
** Creator/StevenMoffat believes there is "a terrible secret" behind why he never gives his true name, to even those he loves.
** River Song knows his name; [[Recap/DoctorWhoS33E13TheNameOfTheDoctor she says]] she ''made'' him tell her, and it took a while.
---> '''Doctor''': River, you know my name! You whispered my name in my ear. There's only one reason I would ever tell anyone my name. There's only one time I could!
** Made into a major plot-point in the series finale of Series 6. It's resolved - but still not answered - in "The Time of the Doctor".
--> '''Doctor''': Silence will fall when the Question is answered.\\
'''Dorium''': Silence ''must'' fall when the Question is answered.\\
'''Doctor''': What is the Question?\\
'''Dorium''': The first question! The question that must never be answered, hidden in plain sight. The question you've been running from all your life! Doctor who? Doctor who? [[PunctuatedForEmphasis Doc! Tor! WHO!]]?
* ObfuscatingStupidity[=/=]ObfuscatingInsanity: He can go from a CloudCuckooLander to an AntiHero in the snap of a finger.
* ObliviousToHints: Trying to list all the Companions (and others) he's driven up the wall doing this to would take a while... How much is deliberate, or just him being scatter-brained, is debatable and, probably, changeable -- even within an incarnation. The TARDIS is also not always impressed, if [[spoiler: her complaint about the door is any indication.]] There is only one that didn't manage to pull this out where we could see it: the War Doctor. But that probably had more to do with not getting the chance to than not being capable of it. The general template is as follows:
-->'''Whoever''':"...Which is why I basically ''asked'' you ''not'' to do that!"\\
'''The Doctor''': "Really?! Well, you should have said so sooner."\\
'''Whoever''':
* OmnidisciplinaryScientist: And quite [[JustifiedTrope justified]] too.
** Just a sampling of the disciplines he has shown proficiency in: biology, anatomy, astrology, astrophysics, paleontology, paleoanthropology, recreational mathematics.
** Judging by statements from old classmates, his original degree/doctorate seems to have been in (astro?)physics and/or engineering (the Rani mentions qualifications in "thermodynamics", the Master "cosmic science"), but he's had a whole lot of time to acquire insane amounts of knowledge, and the curiosity to match.
* {{Omniglot}}: He even speaks baby.
** ...and horse. And dinosaur.
*** This is notably a skill he developed gradually over the series - he didn't speak French during his exile, and picked up the more 'exotic' things like "baby" in the quadruple digits.
* OneMythToExplainThemAll: The show posits that hundreds upon hundreds of myths are based on him and his adventures.
-->'''River Song:''' I hate good wizards in fairy tales; they always turn out to be him.
** Subverted in that example when it turns out that [[spoiler:he's actually the "nameless, terrible thing", soaked in the blood of a billion galaxies. Ouch.]]
** The Doctor also encounters several such creatures and enemies.
* PapaWolf: Towards both his companions individually and the ''entire'' human race.
* PatrickStewartSpeech: The Doctor has waffled on his opinion of earthlings over the years. Thankfully, he can safety be called a humanist. This is in reaction to the many craven adversaries who represent the triumph of an [[TheSocialDarwinist elite]] over the weak. The Doctor holds that even the most ordinary person is unique and worth preserving.
* PercussiveMaintenance: When something goes wrong with the TARDIS' flight -- hitting, kicking, he's even got a special mallet. When Adric tried to "think like the Doctor" to solve a flight problem, his solution was to smack the console. It worked.
* {{Pride}}: An ego of awesome - and very frequently justified - proportions.
* PsychicPowers: The Doctor has some degree of psychic ability, though the details are fuzzy and mostly left up to the writers.
** What we've seen so far is touch-telepathy requiring he put his hands on either side of a person's head. Sometimes he also puts his forehead against their foreheads. And in the case of the latter, [[Recap/DoctorWhoS31E11TheLodger sometimes]] he does it '''''really hard'''''.
** Plus, the Doctors are able to [[Franchise/StarTrek mind-meld]] with each other through "Contact!" (and, when necessary, with others via head-butt).
** Historically, his telepathic mojo has seen the most use when dealing with other Time Lords or other SufficientlyAdvancedAliens. He seems to have only recently become adept enough to mind-meld with ordinary humans and the like. When encountering [[MyFutureSelfAndMe time-displaced versions of himself,]] he can do a mind meld without physical contact.
* PungeonMaster: Sad, but true: give any Doctor an excuse, and they'll find a pun to abuse. Some more than others. For the worst offenders, you need One, Four and Eight. But, any of the others are also more than capable of knocking you over the head with a blunt verbal instrument alongside more subtle wordplay. While looking awfully smug about it, to boot.
* ReallySevenHundredYearsOld: He claims to be 1200 as of "The Day of the Doctor", and according to the ebook ''Tales of Trenzalore'', the Eleventh Doctor spent over 900 years on Trenzalore during the events of "The Time of the Doctor". While various contradictory dates have been given in both the classic and revived series, WordOfGod is that he's pretty much forgotten his true age and by his Ninth and Tenth incarnations, simply began ticking numbers off from 900. What matters is that he's old, ''very'' old.
** By the time of his thirteenth regeneration, he's bumped all the way up to two thousand years old.
%%%
%% Please no natter.
%%%
* RefugeInAudacity: The Second, Fourth, Tenth and Eleventh frequently indulge in this.
* RoboShip: Companions come and go, but the Doctor and the TARDIS love each other eternally. Pretty much confirmed in-universe as of [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]], in which [[spoiler: they get to share a BigDamnKiss and a tremendously sweet AnguishedDeclarationOfLove]]. "The Name Of The Doctor" reveals that [[spoiler: after they die, she becomes his tomb]].
* RummageSaleReject: Even the ones in ''suits'' succumb to this.
* ScienceHero: The Doctors often use their scientific knowledge to save the day.
* SeenItAll: By his Eleventh incarnation. An extended scene from "Flesh and Stone" has him claim that he's probably been to every star in the universe ''twice'' and the reason he ''needs'' to travel with companions is because of their wide-eyed reaction to the wonders of the universe, which he's begun to stop noticing.
* SelfMadeOrphan: It's pretty likely that he killed his parents at the end of the Last Great Time War, although we don't really know whether or not his parents were still alive when he wiped out the Time Lords. WordOfGod from Creator/RussellTDavies is of the opinion [[spoiler:he killed his mother when he ended the Time War. Given that dialogue in ''The End of Time'' reveals Time Lords were being killed and resurrected repeatedly during the War, this may be viewed as something of a release.]]
* ShroudedInMyth: Good wizards in fairy tales tend to turn out to be him. At the very least, he's confirmed to have been - well, will end up being - Merlin.
* SmartPeoplePlayChess: The Time Lords invented the game (as seen with the Game of Rassilon), and Four and Eleven in particular have a fondness for playing chess.
* SmugSuper: Not as bad as some cases, but not exactly quiet about his brilliance, either.
* SniffSniffNom: The Doctor tends to lick things to analyse them; though most seen with 10 and 11, he's occasionally done this as far back as 2.
* SpannerInTheWorks: This RummageSaleReject has turned up while you have an intricate and very delicate plan in play? All bets are now officially off...
* SpellMyNameWithAThe: It would seem that Time Lords who are on the outs with Gallifrey -- renegades, as it were -- have lost their names along with their home. Other examples include the Master (of course), the Rani, and the mentioned-but-not-seen Corsair.
* SuperSenses: ''All'' Time Lord senses are supposedly vastly superior to human senses; in practice, though, this is largely plot-driven.
** Time Lords are also time-sensitive. The Tenth Doctor once describes it as [[OmniscientHero being able to see everything that has happened, everything that can, and everything that must never, simultaneously.]]
** The Ninth also demonstrated that if he concentrated, he could discern the spinning of fast moving fan blades, so that he could walk safely through them... with his eyes closed. He also claimed to be able to feel the Earth's movement through space.
* SuperStrength: Occasionally he does things like punch through a stone wall or break a rock with his bare hands or something to remind you of this, though there's rarely dialogue devoted to it. The Eighth Doctor even managed (after several punches) to knock a steel door off of its hinges immediately following his regeneration.
* SymbolMotifClothing: The Doctor began wearing question marks when John Nathan-Turner took over as showrunner. It started with Five's and Six's collars, as well as Six's suspenders, and culminated in a pullover vest and umbrella for Seven.
** When Four regenerates and Five is taking off Four's attire, particularly unraveling the massive scarf, you can see question marks on his collar, too.
* TechnicalPacifist: The Doctor ''really'' puts the "Technical" in Technical Pacifist. Although he has used firearms on occasions, for the most part he is just very good at engineering situations which result in the destruction of his current adversary (sometimes on a ''genocidal'' scale) if they fail to heed his warnings. He also sometimes outsources violence and killing to companions who don't share his hangups, notably Leela, Jack and River.
* TooDumbToLive: Every so often, the Doctor's pacifism sends him into this territory. While his desire to avoid death is understandable, any time he tries to save long-time enemies such as the Daleks, Sontarans and Cyberman just make people want to slap him. He himself admits that they are bred to do nothing but hate and kill, yet he keeps walking up to them and yelling "Let me save you!", often while they're pointing a gun, laser, etc. at his head, usually risking himself, his companion, and ''the world'' in the process.
** Once, when the Doctor was carrying out the typical "go towards something you should probably be going away from" version, River Song tells one of her crew to go with him and "pull him out when he's too stupid to live."
* TricksterArchetype: Manifested one way or another in every incarnation.
* UnderestimatingBadassery: Consistently the recipient of this. Very often his enemies blunder into his path and completely fail to understand what he's capable of. This even applies to enemies who've encountered him before and ''know'' what he's capable of, but still don't think he can stop them. Only the Daleks seem to have the good sense to be afraid of him.
* {{Unperson}}: The Eleventh attempted to remove all traces of himself from history after getting "[[TheDreaded too big for the universe]]". However, according to River, all that has done is leave a big "Doctor-shaped hole" in history that makes his existence ''obvious'' to anyone looking close enough.
** He fully tried this on the War Doctor, to the point Clara only found out about him after entering the Doctor's timestream.
* WalkingDisasterArea: Goes for most Doctors, but Five in particular was out to set some kind of record.
* WeDoTheImpossible: The Doctor flies in a time machine that can go anywhere and any''when'' in the universe, has saved the Earth more times than he can count, saved the universe and all of reality itself repeatedly. He defeats intergalactic races of pure evil on a daily basis, thinks crippling dictatorships is a rather average outing, and can do all of this with a kettle, a piece of string, and a screwdriver.
--> '''The Doctor:''' Ah, the security protocols are still live. There's no way to override them; it's impossible!\\
'''River Song:''' How impossible?\\
'''The Doctor:''' [[ScottyTime Two minutes]].
* WhoWantsToLiveForever: By the Tenth and Eleventh incarnations, it's not so much ''his'' long life that he's disheartened by, but the fact that he knows that he's forced to watch as his companions grow old and eventually die, all while he remains looking ''exactly the same''. As River Song lampshades, the Doctor doesn't like endings or having to say goodbye. Eleven has actually succeeded all too well at the above goal to "see everything" to the point that [[Recap/DoctorWhoS31E5FleshAndStone he "can't see it any more."]] This actually dates back to the Eighth Doctor -- [[spoiler:after crash-landing on the planet of Karn, he calls the flame of eternal life the "Flame of Utter Boredom."]]
* TheWonka: TheCaptain of a spaceship who gives strange orders and does strange things but usually tend to work.
* YouCantGoHomeAgain: The First Doctor and Susan fled from Gallifrey in a stolen TARDIS and ended up in exile. The Fourth eventually does return home, but has to flee again right away; the Fifth gets out very quickly for the same reasons as the Fourth; the Sixth is forcibly dragged back and vows to never set foot there again. By the time the Ninth Doctor appears, he's destroyed Gallifrey. [[spoiler: However after The Day of the Doctor this seems subverted, but it's trapped in another universe which he apparently can't get to.]]
