-->--'''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, [[AmbiguousGender they]] have a life span measured in centuries, some degree of psychic ability, and the ability to [[TheNthDoctor regenerate]] when near death. Unlike other Time Lords, they became bored and/or terrified by the Gallifreyan way of life when they were young, stole an antique TARDIS, skipped town and "never stopped running".

The Doctor remains the same ''person'' throughout their 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, calm, peremptory, manipulative, romantic, weary, harsh, hyperactive, adorkable and caustic. After the show's return in 2005, it's added a bit more CharacterDevelopment than the classic series.

! In General
[[folder:All Doctors (General)]]
* AbsentMindedProfessor: The Doctor is prone to acting like this, depending somewhat on the [[TheNthDoctor incarnation]]. They're quite likely more intelligent than any human being in history, but they're prone to BuffySpeak, {{Disorganized Outline Speech}}es, {{Metaphorgotten}}, {{Cloudcuckoolander}}-ness in general, and can hardly pilot their TARDIS or even remember what its buttons and knobs do. Sometimes this is ObfuscatingStupidity, but often it isn't.
** In [[Recap/DoctorWhoS31E2TheBeastBelow "The Beast Below"]]:
--->(''the Doctor puts a glass of water on the floor and stares at it'')\\
'''Amy:''' Why did you do that?\\
'''The Doctor:''' Don't know. I think a lot. It's hard to keep track.
* AdmiringTheAbomination: Many Doctors do this at least once in a while, but it's a particular specialty of Ten's.
* AlienNonInterferenceClause: Downplayed. They try to stick to "meet new people, stop threat of the week, then fly off saying IWasJustPassingThrough" - and disapprove of the Monk trying to "improve" history.
** Varying from this trope does come back and bite them in the butt a few times, due to them 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. Twelve [[ThereWasADoor prefers using windows to boring old doors.]]
* AlmightyJanitor: UNIT's "Scientific Advisor", on temporary leave as of, [[ContinuitySnarl uh...]] 1974. UNIT's relationship with the Doctor seems quite schizoid: As an institution, they grant the Doctor dictatorial powers whenever they need their help, while simultaneously hiding things from the Doctor that they know they'll disapprove of (and grumble when the Doctor steals away and hides such contraband from them, even when it is potentially genocidal).
* AlwaysSaveTheGirl: So far, four incarnations (Three, Five, Nine and Ten) have died trading their life for their companion's (it should be noted that in the case of Ten, it was a case of "Always Save the Cool Old Guy"). Subverted with Eight, as he died trying (and failing) to save a woman whom he had set his heart on being his next companion. Taken UpToEleven with the Twelfth Doctor, who sacrifices 4.5 ''billion'' years and risks the entirety of creation to save one young woman.
* AmbiguousGender: A fairly unique case. Each incarnation has a fixed biological sex, but the Doctor can change sex at regeneration and therefore has no intrinsic biological sex. WordOfGod states they are pangender or agender, as we understand it.
** PronounTrouble: Prior to Thirteen, all onscreen incarnations of the Doctor were men, so only "he" was required. However, Thirteen is a woman; since her announcement, the compromise appears to be to refer to individual incarnations as "he" or "she" and to the Doctor as a whole as "they". Another train of thought advocates continuing to refer to the Doctor as a whole as "he", given the majority of their incarnations have been male.
* AmbiguouslyBi: From the Eighth Doctor onwards, they will flirt with their 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. Even back in TheSixties, Jamie and the Second Doctor had fans who saw a truly spectacular HoYay going on.
* AntiHero: Regardless of the incarnation, they're an arrogant and vain old man([[AmbiguousGender ?]]) who does good in spite of themself.
* {{Asexuality}}: The Doctor's known to have had children before they left Gallifrey, but afterwards, while romantic inclination has varied from incarnation to incarnation, they've never really shown sexual attraction to anyone. However, things become a little ambiguous during the Moffat era, thanks to his fascination with the subject. In the original series, there was nothing textual with their companions (even leather-clad Amazonian warrior Leela), but the revival has changed that, giving their relationships more focus.
* AttentionDeficitOohShiny: To varying degrees in every one of their 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 their Third incarnation, when the Time Lords stranded him on Earth. Even then they kept themself amused running around with UNIT.
* AwesomeAnachronisticApparel:
** Doctors One (Edwardian academic garb), Two (long coat and bowtie), Three (smoking jacket, ascot, and ruffled shirt with lace cuffs), Five (cricketer's costume and Panama hat), Eight (frock coat, vest and cravat), Eleven (tweed suit with leather elbow patches and a bowtie) and Thirteen (long coat and trousers with braces). Doctors Four, Six and arguably Seven subverted this trope with bohemian outfits that were ''never'' in style. Nine, Ten and Twelve avert this with a leather jacket (Nine) and contemporary suits (Ten and Twelve) which become anachronistic to their surroundings.
** Even the Ninth Doctor, who outwardly appeared to be wearing the most modern outfit, was actually wearing a Kriegsmarine Captain's Jacket from UsefulNotes/WorldWarII, a similar look to the War Doctor's brown leather overcoat.
** Five ''really'' mixed this up with his choice of an Edwardian-era cricketer's outfit combined with (at the time) modern-day sneakers.
* BadassInDistress: They get tied up, handcuffed and so on almost as often as the companions, if not more.
* BadassPacifist: To an extent. The Doctor usually tries to use their wits to solve problems rather than violence.
* BavarianFireDrill: A master of it. After the introduction of the psychic paper in "[[Recap/DoctorWhoS27E2TheEndOfTheWorld The End of the World]]", the ImpersonationGambit is used more often.
* BecauseYouWereNiceToMe: A possible explanation for their fondness for Earth and humans. They've been much more welcoming to the Doctor than the Doctor's home world has. In-story, they're likely to remember and repay any kindness shown them, provided that person doesn't cross the line with them afterward.
* 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 and the Prince of Wales have their phone number.
* BeingGoodSucks: Every Doctor will find themselves in a morally grey situation with thousands of lives at risk, and TakeAThirdOption isn't always on the table.
--> '''Twelfth Doctor:''' Sometimes the only choices you have are bad ones, but you still have to choose.
* BenchedHero: The after effects of Three, Five, Ten, and Twelve's regenerations put them out of action for a time. Seven was immediately hypnotized to do the Rani's bidding, so honorable mention there. Two, Four, Six, Eight, Nine (as said in the expanded universe), and Eleven hit the ground running.
* BerserkButton: Don't hurt or kidnap their companions. Or try to destroy the Earth; we're their favourite aliens. Don't try to harm or cheat innocent people. Or enslave people, ''especially'' [[PapaWolf kids]]. The usually calm Doctor will end you.
** They have an incredibly short fuse for tyrants and oppressive governments, ''especially'' Gallifrey's. Even their nicer incarnations had way too much fun leaving regimes in flaming ruin.
* 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. The Doctor would probably concur with Creator/MelBrooks who said, "It can take an army to bring down a dictator. But it takes a comedian to destroy them forever".
** Two, Four, Seven, Ten and Eleven are particular masters of this trope.
* BigDamnHeroes:
** Lampshaded by Clara in "Deep Breath". The Doctor is suffering from his usual post-regeneration quirkiness and has apparently abandoned her. Clara predicts that if he really is the Doctor, he will turn up JustInTime to save her. And of course he does.
** All thirteen of them work together to save the day in "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]".
* BigGood: Their name inspires hope in all that is good and terror in all that is evil. Where they go, 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 they'll never be the same.
** Very few partings with companions are not bittersweet. In "[[Recap/DoctorWhoS30E14TheNextDoctor The Next Doctor]]", the Doctor stated that they ultimately break his heart. And both "[[Recap/DoctorWhoS28E3SchoolReunion School Reunion]]" and "[[Recap/DoctorWhoS35E5TheGirlWhoDied The Girl Who Died]]" touch on the emotional toll losing a companion has on the Doctor.
* 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 their foot or forego the need to ''breathe'' for a few minutes, and can withstand massive amounts of electricity. Oh -- and they have two hearts. Not to mention that when they are close to death they can avoid it by essentially reassembling their body and regenerating into a new one, which changes their personality, quirks, likes and dislikes (and on one occasion [[GenderBender gender]]), though they essentially remain the same person.
* BlueBlood: It's heavily implied that the Doctor came from an aristocratic family back on Gallifrey.
** ImpoverishedPatrician: If the run-down state of the barn and its location in a wasteland where the people "don't matter" (according to Rassilon) are any indication.
* BornLucky: With a little help from the TARDIS.
* ABoyAndHisX: A Time Lord and their TARDIS. Or, as she sees it, the TARDIS and her Time Lord. The trope is referenced directly by name - "A boy and his box, out to save the universe" - in "[[Recap/DoctorWhoS32E4TheDoctorsWife The Doctor's Wife]]".
* 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.
* BreakTheHaughty: Each Doctor has a massive ego and each one of them will find themselves put through the wringer eventually because of it.
* BunnyEarsLawyer: They never quite manage to pass as fully human (or whatever race they're impersonating). But they're 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 their 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.
** They've also been Lord President of Gallifrey at least three times, 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 a NoodleIncident), though the Doctor didn't learn their lesson, hence perhaps why it's brought up again in "The Woman Who Lived" where Ashildr/Lady Me tells the Doctor that she looks after the world he leaves behind.
* 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 it in the revived series - although the Doctor isn't the most reliable source when it comes to their own 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.
** Inverted in one of their origin stories. In that story, a young Doctor and Master back on Gallifrey were being bullied and the Doctor snapped, killing one of the bullies. Death appeared and told the Doctor he would have to become her champion. The Doctor volunteered the Master instead, perhaps giving him his StartOfDarkness.
* CatchPhrase: "Of COURSE!"; "I'll explain...later." and of course, "Run!" (Individual Doctors also have their own.) They also tend to introduce themself with some variation of "Hello, I'm the Doctor!"
* CelibateHero: Despite frequently being [[UnwantedHarem accompanied by attractive female companions]], some of whom have an overt romantic crush on them, the Doctor's relationship with their companions remains platonic, despite occasional ShipTease. This makes sense given that Time Lords are effectively immortal, and therefore have less need to procreate. However, they have had children and grandchildren, and eventually marry River Song in the New Series.
* 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. Sylvester [=McCoy=] is affable, but very cold, setting things up to give the enemy just enough rope to hang themselves.
* 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]].
** Clara's speech about how travelling can be an addiction could be pointing to this. The Doctor physically can't stop helping people.
* 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 treats people more like interesting research subjects than like sentient beings, and flirts with a giant T-Rex (then denies that it was flirting).
* ContrastingSequelMainCharacter:
** Most incarnations of the Doctor are the opposite of their previous incarnation in some large, glaring way (while other parts of the characterisation shift more subtly). Over the classic series, the haughty and moody First Doctor was followed up by the {{Hobo}}ish and easy-going Second, who was succeeded by the grumpy, elegant and noble Third, the childish, scruffy and carefree Fourth, the responsible and kindly Fifth, the obnoxious and unstable Sixth, and the playful and Machiavellian Seventh. The Eighth Doctor was honest and romantic, in contrast to Seven's solitary scheming, whereas the Ninth was less trusting and more conflicted. Ten was more chipper than Nine ever got, but also [[BewareTheNiceOnes capable of far more ruthlessness]] when pushed. Ten and Eleven were both young and energetic, but while Ten was arguably more down-to-Earth and relatable to humanity than any other Doctor, Eleven was [[TheWonka completely alien]] and [[SociallyAwkwardHero out of touch with conventions of any kind.]]
** The transition from Eleven to Twelve is fairly explicitly this -- the light-hearted, confident and somewhat goofy Eleventh Doctor, who was essentially an {{Adorkable}} old professor in a young man's body, was replaced by the much grumpier and self-doubting Twelfth, who is best described as a brooding and rebellious teenager with the appearance of an older man.
** Done peculiarly in the Fourth Doctor's first season - half of the creative team wanted to differentiate the new Doctor by making him [[LighterAndSofter lighten up and be wackier]] after such a [[ActionHero serious]] previous Doctor, and the other half wanted to differentiate him by making him [[DarkerAndEdgier darker and more brutal]] after such a [[IdealHero noble]] previous Doctor. It is a real testament to the ability of Creator/TomBaker and Creator/RobertHolmes that they managed to pull off both, at the same time.
* 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. And the four oldest incarnations in terms of the actor hired to play the role (William Hartnell, Jon Pertwee, John Hurt and Peter Capaldi) definitely fulfill the trope.
* CourtroomAntic: Rather than face the indignity of hearing a guilty judgement during his mockery of a trial, the Fourth Doctor put himself up as a candidate for the Presidency. Six spent the bulk of his own trial heckling the prosecutor (the Valeyard), calling him Boneyard/Backyard/Barnyard/Knacker's Yard/etc.
* CrewOfOne: Half the reason they [[DrivesLikeCrazy Drive Like Crazy]] is that they're trying to do a six-person job, occasionally with a companion following their advice.
* CruelMercy: Most of the time, they are nice enough to let their enemies surrender or redeem themselves. But if you've crossed the line? You'll ''wish'' you were just killed outright. Seven and Ten, in particular, could be ''incredibly'' brutal in handing this out.
* 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", "The Time of the Doctor" and "Twice Upon a Time".
* DefectorFromDecadence: The circumstances behind them leaving Gallifrey (other than a desire to see the world) are unclear, but they were always critical of the stagnation of Time Lord society.
* DependingOnTheWriter: Depending on the incarnation, the Doctor can be anything from an angry, grumpy, callous, arrogant, [[PragmaticHero ruthless]] JerkWithAHeartOfGold AntiHero to a fun-loving, eccentric, clownish, childlike alien with an [[BewareTheSillyOnes unscrupulous, manipulative streak]] to a dashing, charismatic, heroic CulturedBadass [[TheAce Ace]] with InsufferableGenius tendencies to an {{Adorkable}}, sensitive, vulnerable, fallible GentlemanAndAScholar.
* DeusExMachina: When you think about it from the perspective of a lot of the characters who only show up in one story, the Doctor themself 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 weirdo and their 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 their enemies with a look of utmost calm.
* DoesntLikeGuns: No version of the Doctor has been exactly gun-happy, though some accepted them [[BatmanGrabsAGun as a last resort]] (though rarely bullet-firing guns).
** 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. He did carry a gun during an adventure in the wild west (in the {{novelization}} he even shoots someone by accident), but that was more to be in character.
** Two 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 ray 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 with a ray gun, 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" (again, though, it was a laser gun, not a bullet gun). 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 (a rare occasion where a bullet-firing gun was used). Other times, he simply refuses to acknowledge them as guns, [[InsaneTrollLogic because "I don't use guns."]]
** Unexpectedly played straight with the War incarnation, about whom [[Recap/DoctorWhoS35E12HellBent his being unarmed]] was reportedly the first thing you notice ([[BadassBoast and for many, also the last]]). 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'''. When his cloned daughter appeared to have been shot to death, he picked up the gun that did it and appeared to be about to blow away the man who fired, but said he never could. However, Ten did pick up a gun on his last day, when he realized that the Time Lords were returning. And he pointed it at Rassilon. He ended up firing the gun, though 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.
** Twelve's opinion of guns is made clear when he tells a group of soldiers they don't have to be liked because they have the guns. However, he can be pushed far enough to pick one up: in the Series 9 opener, Clara's apparent extermination gets him angry enough to pick up a Dalek gun and aim it at Davros, although he ultimately decides to use it for something else, while in "Hell Bent", given the chance to rescue Clara from her imminent death, he actually fires a gun at someone (again, though, not a bullet gun).
* 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 them neck deep in it. Either way: they arrive; trouble happens; trouble unhappens; they leave. 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 themself "Doctor" is immediately browns their trousers. A number of times the Doctor themself calls attention to their identity for that effect.
** This effect seems to be especially prevalent with the Daleks, who nearly destroyed the entire Time Lord race in the Last Great Time War. [[Recap/DoctorWhoS33E1AsylumOfTheDaleks To put things into perspective]]: There are Daleks deemed -- by their own race of hate-filled 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".
** When the Doctor finally returns to Gallifrey and returns to his childhood home, a gunship shows up to drag him off. When he takes a step forward, the gunship backs up. The Doctor then draws a line in the dirt with his foot, and no one will cross it.
* DrivesLikeCrazy: In River Song's second appearance, she teases that the Doctor 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 the Doctor is 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 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 they need to be.
* DyingAlone: The Seventh, Eighth, War, Tenth and Twelfth Doctors all regenerated alone (though given that the last three were in the TARDIS, they don't count as a full example).
* EccentricMentor: To many of their companions.
* EraSpecificPersonality: The Doctor changes personalities in every regeneration.
* EternalHero: They're always there to save the day, anywhere and anywhen they are needed.
** Though sometimes [[Series/TorchwoodChildrenOfEarth he]] [[Series/TorchwoodMiracleDay isn't]], a fact explicitly pointed out in the former incident.
* EveryoneCallsHimBarkeep: Perhaps one of the most famous examples, and an invoked and justified one at that. The Doctor refuses to use their true name, taking their name as "The Doctor" and only that. According to them, it is a promise, as symbol of who they are or rather want to be: Somebody who wants to help and heal. Of course, this leads to the classic RunningGag...
--> "[[TitleDrop Doctor WHO?]]"
--> "[[PhraseCatcher JUST... The Doctor.]]"
* {{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.
* ExtremeOmnisexual: One time, The Doctor flirted with a sentient tree and a Dalek (albeit one with the consciousness of a cute human girl), they and their sapient spaceship are bonded to the point where the show calls her their wife, and they note that although they find Zygons physically repugnant, the species are surprisingly good kissers.
* FamedInStory: Erratically, since they tend to hop around space and time and are not actually ''universally'' known -- but happens on many occasions.
** It's later been revealed that, due to them, countless races across the universe ''do'' get the word "Doctor" intrinsically ingrained in their languages, 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, they are very much this. [[AGodAmI Bad things happen]] when they start breaking their 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 the [[{{UnPerson}} War Doctor]] can attest to that.
* FigureItOutYourself: They invoke the "changing the future" excuse. Taken to massive extremes in "Kill The Moon" to the point in which he leaves a decision that could kill the entire planet to Clara and two others. Though it was all a test and he knew they wouldn't do it, and when Clara found out the truth, it alienated her to the point where she almost left the TARDIS for good.
* {{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.
* FlatEarthAtheist: The Doctor, despite being a person who flies through space/time like it was a Sunday drive and has fought monsters, has very little patience for non-science based explanations, and refuses to accept there are such things as ghosts, Gods, and devils (though Twelve finally comes to accept ghosts). It becomes very obvious when they come across things, creatures, and events that have ''no'' reasonable explanation, sometimes going so far as to ignore explanation and adopt a "It happened let's move on" mentality.
* 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''': How can you have a grave?
--> '''Doctor''': Because we all do, somewhere out there in the future, waiting for us.
* {{Foil}}: Each Doctor is a subversion of the previous one, but it's at its fullest extent with the War Doctor. Whereas his predecessors and successors are all {{technical pacifist}}s with varying degrees of egotism, chessmasterness, etc., the War Doctor is a warrior with countless deaths on his hands, and is the most humble of his selves. It's most evident when he meets his future incarnations in "The Day of the Doctor": Ten and Eleven are cheerful {{man child}}ren with deep-rooted dark sides, while the War Doctor is dark on the outside, very mature and war-worn, with his good heart buried deep within himself. It is as if he was a yin-yang inverse of himself.
** The Third Doctor was exiled to Earth, so the Fourth Doctor contrasted this with always being unable to sit still or take orders from authority.
%% ** For other specific Doctor comparisons, please list them here or on their pages.
* FriendlessBackground: More than once, and more so in the newer series, it's been mentioned that the Doctor had a very lonely childhood, with one mention of them often being left out by other Gallifreyan children. In fact, about the only friend of theirs we know of is '''The Master'''.
* GenderBender:
** Missy claims to have known the Doctor "since he was a little girl", and if the two of them are to be trusted (a tall order, to be fair), that was not a lie.
** Thirteen is their first confirmed female incarnation.
* GeniusSweetTooth: Four loved Jelly Babies; Eleven preferred Jammie Dodgers.
* GentlemanAdventurer: Even once they start to think of fighting the bad guys as a job, their main objective has always been to see as much of the universe as they can.
* AGodAmI: An immortal, omniscient alien with a time machine? ....Just get down on your knees and pray that they're never, ever in this mood around you.
* AGodIAmNot: Their usual mode. They usually don't expect people to recognise them, let alone view them as a hero or (horrors!) see them as a being of nigh-invincible power; they're 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.
* GoodIsNotNice: They're marvelously rude to practically everybody they meet (even those on their side), and the only people they show genuine affection for are children and their companions.
* GuileHero: Almost every incarnation of the Doctor prefers to use brains over brawn.
* HalfHumanHybrid: The idea's been brought up a couple of times, though whether it's true is uncertain. [[RuleOfCautiousEditingJudgment It's a delicate subject in the fandom.]] Eighth says he's half-human on his mother's side, and Ashildr/Me independently proposes it as a theory to explain the Doctor being the Hybrid of Time Lord prophecy. (The Expanded Universe has gone both ways with Eighth's statement and its supporting evidence, some parts going along with it, other parts claiming he was faking out the Master.)
* HeadbuttingHeroes: With UNIT, people [[DoesNotLikeGuns who use guns]] and even with ''[[MyFutureSelfAndMe themself]]'' on occasion.
* TheHero: In the words of Donna: "He saves worlds, rescues civilizations, defeats terrible creatures and runs a lot. Seriously, there's an outrageous amount of running involved. "
* HeroesLoveDogs: Tin ones, in particular. Ten and Eleven still have nostalgia for K-9 and other robot dogs.
* HeroesPreferSwords: While the Doctor isn't an action hero, they're not adverse to a swordfight, as shown in their third, fifth and tenth incarnations. The 12th Doctor once dueled Robin Hood, though it was with a spoon, rather than a sword.
* HumanAliens: On the surface, they look perfectly human, though Ten and Eleven have argued that 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 their race are completely different down to an anatomical and biochemical level. Just detecting their two hearts is enough to convince most human(oid)s of what they are (at least post-"The War Games"; before that point, they're AmbiguouslyHuman).
* HumbleHero: They're not modest, but they're essentially humble - might seem odd, but it's true. Though they show pride over their own brilliance and abilities, they don't consider themself special, they'd just as soon leave any credit for what they do to someone else, are very aware the universe doesn't revolve around them and don't think it should, have dismissed any offers of power to them with some variation on "I wouldn't be very good at it", and can't seem to see that they're powerful enough that whole races devoted to the subjugation of the universe have banded together to try to destroy them.
* IconicItem: The Sonic Screwdriver and the TARDIS, of course. From 2005, the psychic paper.
* IHatePastMe: Tends to come up whenever [[MyFutureSelfAndMe interacting]] with their past or future incarnations.
** ''The Three Doctors'' started this trend with having Two and Three often squabbling amongst themselves, with One occasionally reining them in and telling them to focus on the task.
** In relation to the point above, when it comes to in-fighting between incarnations, One has generally been the exception, especially in the expanded universe. Most of his successors who have interacted with him have seen him as a voice of reason, treated him with immense respect, and have always followed his advice.
** 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).
** Meanwhile, when Ten and Eleven met they got along rather well, their squabbles being more akin to playful witty banter and the two sharing more than a few of their more expressive mannerisms.
* TheILoveYouStigma: WordOfGod is that the Doctor should never say these three little words, even when the situation is appropriate. Although less of an issue in the Classic Era, there were still moments where he could have said "I love you" in a platonic context, if nothing else. In the Modern Era series, even in unambiguously romantic relationships such as with Rose Tyler, Clara Oswald, and even their own ''wife'', River Song, the Doctor is never heard to utter the phrase. Instead, they either waffle around it (as the Tenth Doctor does with Rose in [[Recap/DoctorWhoS28E13Doomsday "Doomsday"]], saying instead "Does it need saying?" though his clone is implied to have whispered it to her in the later [[Recap/DoctorWhoS30E13JourneysEnd "Journey's End"]]) or uses a euphemism such as "Do you think I care so little for you that betraying me would make a difference?" in [[Recap/DoctorWhoS34E11DarkWater "Dark Water"]] (confirmed by the showrunner and writer of the episode as a euphemism for "I love you") and "I had a duty of care" ([[Recap/DoctorWhoS35E12HellBent "Hell Bent"]]). Sometimes other characters prevent them from having to say anything approaching it (as with Clara Oswald saying "Whatever you're about to say, I already know" as they prepare for her death in [[Recap/DoctorWhoS35E10FaceTheRaven "Face the Raven"]]).
* ImNotAHeroIm: ...just a madman/idiot with a box, helping out where they can. They've shown elements of this throughout their lifetime, but only recently have they really started to enforce the idea that they're most certainly ''not'' a hero; Eleven and Twelve in particular both had to force their companions to accept this.
* IMeantToDoThat: Some things just never change, and every Doctor pretends they have piloted the TARDIS exactly where they intended even if they're way off-course.
** "The Doctor's Wife" justifies this when the TARDIS itself reveals that it always takes the Doctor and their companions not where they want to go, but NEED to go.
* 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 a bit dodgy, this process."
** An alternate view of the trope: as stated in "[[Recap/DoctorWhoS28E3SchoolReunion School Reunion]]", the Doctor is always cognizant that they will always outlive their companions, stating to Rose Tyler, "You can spend the rest of your life with me, but I can't spend the rest of my life with you. That's the curse of the Time Lords." To date only three companions potentially could defy this, but the Doctor is unable to stay with them: Romana (a younger fellow Time Lord), Jack Harkness (after being rendered immortal by the Bad Wolf) and Clara Oswald (post-"Hell Bent").
* IndyPloy: Has been winging it since they got stolen by a TARDIS. They're generally rather good at it, to the point their plots can resemble multi-step plans, rather than the "pick stuff up, press stuff and/or prod it, and run with (or away from) what happens" they most probably are.
* InexplicablyAwesome: The Doctor is, quite frankly, oddball even for a Time Lord (heck, just liking Earth, let alone a particular corner of the universe that isn't Gallifrey, is outright weird for them). ''And we '''''still''''' don't really know all that much about how they got to be that weird by their standards.'' Seriously.
* InHarmsWay: Nothing keeps the Doctor from adventure.
* InTheBlood: The Doctor's character flaws - pride, arrogance, self-absorption, and inclination to think themself superior to others - are all traits that can be found in every Time Lord from Romana to the Meddling Monk. And of course, they're passed down with every regeneration.
* 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 they get up to when their companions are asleep. They do sleep on occasion but, as Twelve tells Clara in "[[Recap/DoctorWhoS35E9SleepNoMore Sleep No More]]", they do it when no one is looking.
* JumpedAtTheCall: They didn't just jump, they stole a TARDIS and went looking for it. [[Recap/DoctorWhoS32E4TheDoctorsWife Or did she steal them?]]
* 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 they expect to find people to help wherever they go and embrace 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. He is throughly broken throughout his Big Finish storyline, and when he reappears on-screen at the time of his last adventure, and his regeneration, he'd become quite sour indeed.
* LargeHam: Comes with the WorldOfHam the series is set in. All Doctors are hammy in their own way.
%%* TheLastDJ: In the Classic Series, they were often this to the rest of the Time Lords.
* LiesToChildren: When expounding on things beyond their Companions' ken (particularly anything to do with Time Lord tech), they'll resort to simplified analogies. Some of which work better than others; many of which get weirder than others, depending on which Doctor is explaining things. Eleven and Twelve get bonus points for regularly finding actual kids to analogy at.
* LikeAnOldMarriedCouple: With the TARDIS. Because they totally are. And with other regenerations of themself: very few of them actually get along, and Two and Three in particular spend every moment bickering.
** The Doctor's relationship with some of their companions resemble this at times. Examples include Sarah Jane Smith, Romana (particularly the second Romana), Tegan, Peri, Donna and Clara. The trope is also applied literally with regards to River Song.
* 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 eventually moved on to a more modern outfit in AudioPlay/BigFinishDoctorWho - for a [[UsefulNotes/WorldWarI given value]] of modern, anyway.) The Ninth, Tenth, Eleventh and Twelfth Doctors return to the original method, with certain items (the leather jacket, trainers, tweed jacket with bowtie, and boots 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 waistcoat.
** 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 they particularly [[ObliviousToHints don't want to get]], so if this is [[FridgeBrilliance one of her hints]] about their taste in fashion, they're 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.
** Also began to be averted as the series introduced the notion of romance between the Doctor and the occasional companion. As the Tenth Doctor states in "[[Recap/DoctorWhoS28E3SchoolReunion School Reunion]]", his companions will grow old and die, but the Doctor will just keep on regenerating. This becomes an underlying theme of Series 9 as the Twelfth Doctor becomes fixated on the possibility of one day losing Clara, arguably one of his most beloved (literally and figuratively) companions.
* LivingLegend: Some love the Doctor, some hate them, but they're known throughout the universe. River Song mentions that they can make an army turn and run at the mere mention of their name--and it has been shown that she was not exaggerating.
* LossOfIdentity: Every regeneration must deal with this and discover their 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, they veer into this territory.
* MagneticHero: Everything gravitates towards them, first and foremost, their Companions.
* MasterOfUnlocking: And ''locking'', at that, thanks to the sonic screwdriver.
* MayflyDecemberFriendship: They're a centuries-old alien with an indefinite lifespan, and the majority of their companions are ordinary humans. Even with a time machine, they're eventually going to outlive all of them. This is the main reason they tend not to visit the companions after they leave, and is painfully demonstrated when Eleven learns the Brigadier has passed away.
* MayflyDecemberRomance: Any time they get involved with a non-Time Lord, this is the inevitable result.
* MrExposition: Since they typically know more than anyone else does.
* MrFixit: Even once jokingly called themself "the maintenance man of the universe".
* MrSmith: Almost every time the Doctor needs a name, they simply use the bland pseudonym "John Smith." This is even the Third Doctor's official legal name during his time stranded on Earth working for U. N. I. T.
* MyFutureSelfAndMe: Occasionally, they team up with one or more of their own future incarnations.
** "The Three Doctors": First, Second, and Third
** "The Five Doctors": First, Second, Third, Fourth, and Fifth
** "The Two Doctors": Second and Sixth
** "Time Crash": Fifth and Tenth
** "The Day of the Doctor": War, Tenth, and Eleventh
** "Twice Upon a Time": First and Twelfth
* MysteriousPast: The franchise has been around for fifty years and we still do not know the Doctor's real name or why they no longer use 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 their home planet until Jon Pertwee took the reins.
** We know they 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.
** Neil Gaiman toyed with providing an origin for the Doctor in 'The Doctor's Wife'. Moffat turned down the idea, explaining the Time Lord does what they do "for reasons too vast and terrible to relate."
* NamesToRunAwayFromReallyFast: "Doctor" doesn't always mean "healer" anymore in cultures they've visited. Then there's the other things some of them call them: the Bringer of Darkness, the Oncoming Storm...
* NeverAcceptedInHisHomeTown: The Doctor has never gotten on particularly well with most of their fellow Time Lords. Even though they've saved Gallifrey multiple times, the High Council tends to view them as an embarrassment. Their saving the whole planet from the Time War seems to have brought many of the soldiers and ordinary citizens around to supporting them, but the higher-ups were still not fond of them.
* TheNicknamer: Several incarnations are known for this, from the First Doctor's intentional mangling of Ian Chesterton's name, to the Twelfth Doctor referring to Danny Pink as "P.E." (initially with contempt, but finally with affection).
* NightmareFetishist: Depending on the situation and Doctors, the Doctor has shades of this, as they practically squee being around particularly interesting (regardless of how terrifying) [[MonsterOfTheWeek monsters of the week]]. This trait was what drove the First Doctor to explore Skaro, as he knew how dangerous it was but faked a TARDIS breakdown to explore a Dalek city. This was even lampshaded by Clara, who asked Twelve if going on dangerous adventures is an addiction.
* NinjaPirateZombieRobot: The Doctor is a psychic alien time-traveling slider.
* NoNameGiven: The Doctor ''does'' have a name, but it's never been revealed.
** There seems to be some sort of cultural convention for Renegade Time Lords to discard their birth names in favor of chosen titles (The Master, the Rani, the Monk, the Corsair...), but while Expanded Universe works featuring their pre-exile days will generally give their personal names, the Doctor doesn't seem to have used their birth name since childhood - their former classmates at the Academy knew them only as 'Theta Sigma', a nickname they apparently found somewhat embarassing.
** Creator/StevenMoffat believes there is "a terrible secret" behind why they never give their true name, to even those they love.
** River Song knows their name; [[Recap/DoctorWhoS33E13TheNameOfTheDoctor she says]] she ''made'' them 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!]]?
** Missy claims the Doctor's name actually ''is'' "Doctor Who" in "World Enough And Time", though the Doctor denies it. Given that both of them are {{Consummate Liar}}s there's no way to know who's telling the truth.
* NoodleIncident: Their final break from Gallifrey, though it apparently involved boosting the Hand of Omega before they left. We know the origins behind the other renegades: The Master went off his nut, and the Rani's mutant mice attacked the President.
-->'''Runcible:''' --?? Oh, I say. Weren't ''you'' expelled or something? Some scandal?\\
'''Fourth Doctor:''' Oh, [[BlatantLies it's all been forgotten about now]], old boy.\\
'''Runcible:''' Oh, really? Well, where've you ''been'' all these years?\\
'''Fourth Doctor:''' Oh, here and there, 'round and about.
* NotSoDifferent: They cut ties with their fellow Time Lords because they found those Time Lords prideful, self-absorbed and arrogant, and yet no matter the incarnation they still possess the same negative personality traits.
* NotThatKindOfDoctor: Initially. He says this almost word for word in one of the first episodes. Later in the classic series, the Rani, a fellow Time Lord and former classmate, mentions the Doctor's qualifications in thermodynamics, indicating that they were initially a ''physicist'', not a physician, but then they went traveling the Universe for centuries with the explicit purpose to learn and explore. By the New Series, this has made them an Omnidisciplinary Scientist, which includes the occasional bit of medical knowledge. Physics and Engineering are still their forte, though.
** In "The Moonbase", Two claims he got a doctorate under Joseph Lister in Glasgow in 1888, although Lister left Glasgow long before that; Clara later asserts that he only graduated in the wrong century by mistake.
* ObfuscatingInsanity: They can go from a CloudCuckooLander to an AntiHero in the snap of a finger.
* ObiWanMoment:
** "A tear, Sarah-Jane? No, don't cry. While there's life, there's..."
** The Fourth Doctor smiled weakly at his companions huddled around him, then gestured to his guardian angel, The Watcher.
** The Ninth briefly held off his regeneration so he could comfort Rose and prepare her for what's going to happen to him.
** The Tenth Doctor willingly surrendered his life to save Donna's grandfather's, despite the old man's pleas. "Wilfred, [[ItHasBeenAnHonor it's my honour.]]"
** Eleven's send-off was a pithy farewell to both Clara and the fans as well. "I will always remember when the Doctor was me."
** Twelve took the opportunity to remind his successor of what being the Doctor means before finally giving himself over. "Doctor... I let you go."
* ObliviousToHints: Trying to list all the Companions (and others) they've driven up the wall doing this to would take a while... How much is deliberate, or just them being scatter-brained, is debatable and, probably, changeable -- even within an incarnation. The TARDIS is also not always impressed, if 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''': <disbelief response tailored to character goes here>
* OlderThanTheyLook: All incarnations of the Doctor are technically part of the same millennia long lifespan, but One, Three and Twelve are the only ones that look like they're older than sixty. Honourable mentions to War, who's indicated to have started out young in "Night of the Doctor" and lived long enough to become the old soldier of "Day of the Doctor", and Eleven, who also lives long enough to go from being boyish to an old man, still fighting even when he's practically senile and needs a cane to get around.
* OmnidisciplinaryScientist: And quite [[JustifiedTrope justified]] too. They've had thousands of years to learn.
** Just a sampling of the disciplines they have shown proficiency in: biology, anatomy, astrology, astrophysics, paleontology, paleoanthropology, recreational mathematics.
** Judging by statements from old classmates, their original degree/doctorate seems to have been in (astro?)physics and/or engineering (the Rani mentions qualifications in "thermodynamics", the Master "cosmic science"), but they've had a whole lot of time to acquire insane amounts of knowledge, and the curiosity to match.
* {{Omniglot}}:
** While they usually have the TARDIS to translate for them, they can speak several alien languages without it. They even speak baby. And horse. And ''dinosaur''.
** This is notably a skill they developed gradually over the series - they didn't speak French during their 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 them and their 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 they're actually the "nameless, terrible thing", soaked in the blood of a billion galaxies. Ouch.
** The Doctor also encounters several such creatures and enemies.
* OurPresidentsAreDifferent: Taking advantage of an obscure law, the Fourth Doctor narrowly avoids execution by putting himself up as a candidate for Lord President of Gallifrey. He claims the position later on as part of a plan to lure would-be invaders the Vardans into a trap, only to have his memory of that adventure wiped, and by the time Romana shows up, someone else has become President. The Fifth Doctor gets appointed President after Borusa is trapped by the Game of Rassilon, eventually getting deposed by "Trial of a Time Lord" for neglect. The Twelfth Doctor, meanwhile, gets appointed the nominal "President of Earth" in times of crisis, and President of Gallifrey again after he deposes Rassilon.
* PapaWolf: Towards both their companions individually and the ''entire'' human race.
* PatrickStewartSpeech: The Doctor has waffled on their opinion of earthlings over the years. Thankfully, they can safely 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, they've 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.
** Deconstructed on many occasions like ''Midnight'' or the Harriet Jones debacle.
** Every Doctor feels the need to be the one in charge and give orders, not take them.
* 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 they put their hands on either side of a person's head. Sometimes they also put their forehead against the other person's forehead. And in the case of the latter, [[Recap/DoctorWhoS31E11TheLodger sometimes]] they do 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, their telepathic mojo has seen the most use when dealing with other Time Lords or other SufficientlyAdvancedAliens. They seem to have only become adept enough to mind-meld with ordinary humans and the like after the Time War. When encountering [[MyFutureSelfAndMe time-displaced versions of themself,]] they 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: Eleven claims to be 1200 as of "The Day of the Doctor", and according to the ebook ''Tales of Trenzalore'', 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 they've pretty much forgotten their true age and by their Ninth and Tenth incarnations, simply began ticking numbers off from 900. What matters is that they're old, ''very'' old.
** By the end of their Eleventh incarnation, they've bumped all the way up to two thousand years old.
** The First Doctor was 450 or thereabouts when he regenerated, the Fourth was 748 when he first started running, the Fifth was exactly 814 when he started, the Sixth was exactly 900, and the Seventh was 953 when he first appeared (The same age as the Rani). Of course, the Doctor started losing track of how old they were way back in their Fourth incarnation.
* RefugeInAudacity: The Second, Fourth, Tenth and Eleventh frequently indulge in this.
* ResignationsNotAccepted: ''Technically'' they never resigned as UNIT's Scientific Advisor, so they'll often find themself roped into helping them on this pretext, whether they want to or not.
* ResurrectionSickness: Several of the Doctor's regenerations have left them loopy, sick, or otherwise out of sorts when bringing themself back to life. For example:
** [[Recap/DoctorWhoS4E3ThePowerOfTheDaleks Two]] is in pain for a while right after regenerating.
** [[Recap/DoctorWhoS7E1SpearheadFromSpace Three]] spends an episode escaping from a hospital.
** [[Recap/DoctorWhoS12E1Robot Four]] spends an episode trying to convince everyone that he doesn't need to go to the hospital because he's fit as a fiddle, but instead convinces them that he's not particularly sane.
** [[Recap/DoctorWhoS19E1Castrovalva Five]] removes random articles of clothing, forgets and remembers everything about himself at random intervals, temporarily reverts back to previous personalities, passes out multiple times, goes crazy, rides around in circles on a motorized wheelchair, floats in the air, spends an episode in a cabinet-coffin thing that Nyssa and Tegan have to carry him around in, and loads more ridiculous things. Needless to say, he had the most known problems thus far. This was true to the extent that the TARDIS thought it appropriate to drop medical supplies on his head at one point.
** [[Recap/DoctorWhoS21E7TheTwinDilemma Six]] becomes dangerously psychotic and suffers from violent mood swings, first convincing himself that Peri is a spy and trying to strangle her, then declaring that he needs to become a hermit for everyone's safety when he realizes what he almost did.
** [[Recap/DoctorWhoS24E1TimeAndTheRani Seven]] and [[Recap/DoctorWhoTVMTheTVMovie Eight]] both lose their memories for a while (although for Seven that was more because he'd been drugged by the Rani). Eight had it particularly bad due to the regeneration taking longer than normal to kick in (he died in surgery and the anesthetic kept him dead "too long".)
** [[Recap/DoctorWho2005CSTheChristmasInvasion Ten]] briefly becomes extremely erratic and irrational before collapsing into a dramatic coma which lasts for most of the episode, and at one point, thanks to [[ItMakesSenseInContext being woken up too early]], his ''brain almost collapses''.
** [[Recap/DoctorWhoS31E1TheEleventhHour Eleven]] has random fits of hitting himself, sometimes spasms painfully, has erratic and odd cravings for food, [[WatchOutForThatTree and walks into a tree]]. "Early days. Steering's a bit off."
** [[Recap/DoctorWho2013CSTheTimeOfTheDoctor Twelve]]'s first action is to complain about the colour of his kidneys, and from there on out he forgets how to fly the TARDIS, discovers to his horror and confusion that he has obtained some kind of face blindness, and struggles with episodes of delirium and amnesia. It takes him a good chunk of the [[Recap/DoctorWhoS34E1DeepBreath following episode]] to get his bearings.
* 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 they get to share a kiss. "The Name Of The Doctor" reveals that after both of them die, she becomes the Doctor's tomb.
* RummageSaleReject: Various incarnations take this approach to their outfits. The later versions tend towards less outlandish but nonetheless distinctive looks.
** The Second Doctor had a many-pocketed, unkempt coat to go with his 'space hobo' look.
** The Third Doctor wore velvet smoking jackets and frilly shirts that Creator/JonPertwee had worn precisely because they looked silly. He also wore a ''cape'' most of the time. And his hair, fluffed out with rollers because the actress playing his companion teased him about his bald spot, slowly increased in size as his tenure went on. He also had a tattoo (in the 1970s, before it was cool).
** The Fourth Doctor's first season outfit is a horrible shabby mess - an ugly shirt, a corduroy jacket with patches on the elbows, a tacky brown and yellow argyle cardigan, a crumpled up scarf used as a tie, scuffed shoes and baggy trousers - the aim being to reflect how young he was compared to the previous Doctors, foregoing 'mad professor' in favour of 'starving student'. And there's that scarf; a [[ThrowItIn happy accident]] (they bought too much wool for the old lady who knitted it expecting her to only use what she needed to make a normal scarf, but instead she thought she was supposed to use it all up). As the Doctor's character developed it was decided he should begin to look [[ByronicHero bohemian and byronic]] - he grows his sideburns out longer, ditches the jacket for frock coats, swaps the cardigan for waistcoats, the scuffed shoes for boots with tall heels, and the tacky shirt for a plain ivory shirt with voluminous Victorian-style sleeves, themes he sticks to for the whole of the rest of his tenure. Having established a beautiful and romantic taste in fashion, he then goes on to bury it under huge hair, a big floppy hat and several layers of hideous and ill-matching scarf significantly longer than he is tall, with awesomely disastrous visual results. Certain stories exploit this by having him remove all the mismatched parts of his outfit [[SheCleansUpNicely in order to give him a few moments of looking actually good]], usually when he's supposed to be dashing and romantic, or DarkerAndEdgier ("[[Recap/DoctorWhoS14E2TheHandOfFear The Hand of Fear]]", "[[Recap/DoctorWhoS14E3TheDeadlyAssassin The Deadly Assassin]]", some scenes in "[[Recap/DoctorWhoS15E3ImageOfTheFendahl Image of the Fendahl]]", "[[Recap/DoctorWhoS14E6TheTalonsOfWengChiang The Talons of Weng-Chiang]]" and the punting scene in "Shada" come to mind). He tends to stick to browns with the occasional dash of dark red or purple - WordOfGod says the colour palette was inspired by the tendency to describe Creator/TomBaker's [[BadassBaritone distinctive voice]] as "[[TastesLikePurple dark brown]]". Early on he also has a habit of doing his buttons up wrong - he buttons up his cardigan so one side is longer than the other, buttons up his frock coat so the double-breast doesn't cross right, and (in "The Masque of Mandragora") does up his waistcoat all the way to the bottom, creating a weird bulge.[[invoked]]
** The Fifth Doctor's red-trimmed cricket outfit and decorative vegetable. Not many men can pull off a decorative vegetable.
** The Sixth Doctor's ridiculous clown suit (to match his ego-inflated personality). At a who-con in Tampa, Creator/ColinBaker told the audience that he had chosen his garish coat specifically because ''he'' didn't have to look at it.
** The Seventh Doctor's question-mark sweater (with question mark-handled umbrella) which ''might'' just have gone too far.
** Subverted by the Eighth Doctor, who stole his outfit from the locker of someone who was going to a costume party. After rummaging through and apparently giving a certain amount of consideration to some really costume-y things, he settled on a rather peculiar but elegant Edwardian suit.
** The Ninth Doctor averts this: his dark pants, dark-colored v-neck t-shirt, and a black leather coat coordinate nicely -- though the coat may not be the best thing to be wearing in WWII England, as Captain Jack notes.
** The Tenth Doctor wears a brown pinstripe or blue suit (it varies) with an open collar shirt, a tie and... Converse trainers (in three varying colors). Not to mention the [[BadassLongcoat duster]]. Believe it or not, the whole thing works.
*** The trainers-with-suit looked odder when Ten's stint started than it does now, since while it hasn't exactly become a trend, it definitely has its imitators.
** The Eleventh Doctor got most of his outfit from what was lying around in a hospital while he was fighting two StarfishAliens. The old professor outfit with a bowtie is actually one of the more "normal" ones.
*** For one brief, shining moment in the season finale, Eleven's outfit consisted of tight pants, button-down shirt, tweed jacket, suspenders, bowtie, and ''[[NiceHat a fez]]''. [[{{Cloudcuckoolander}} While holding a mop]], [[CrazyAwesome for no particular reason]].
*** And at the start of the next season, he has a stetson. However, River Song doesn't like him in hats and has an... ''unambiguous'' way of demonstrating this.
*** There's also his long-johns which he wore for the majority of "The Crimson Horror". ItMakesSenseInContext but especially on Matt Smith's lanky frame, the effect is more than a little silly.
** The Twelfth Doctor's outfits tend to be minimalist, and he seems to put more effort into looking fashionable, but then there's the look he describes as "aiming for mysterious, but ended up as street magician," consisting of a black shirt dotted with white holes, hoodie, and his signature navy blue coat with red interior trim, sometimes with ''plaid trousers.''
** The Thirteenth Doctor's look, comprising a blue top with rainbow stripes, short blue trousers with suspenders, and a long pale lilac coat, is described on her own page as "raided the wardrobe of a 1980s' British kids' TV show."
* ScienceHero: The Doctors often use their scientific knowledge to save the day.
* ScrewDestiny: Death at Lake Silencio a fixed point? Dodged. Their unavoidable destined death at Trenzalore? Not so destined. Time Lords limited to twelve regenerations and then they die for real? [[Recap/DoctorWho2015CSTheHusbandsOfRiverSong "A thing happened."]]
* SeenItAll: By their Eleventh incarnation. An extended scene from "Flesh and Stone" has Eleven claim that he's probably not only been to every star in the universe, but seen their beginning and end, too; 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.
-->'''The Doctor:''' Make all of time and space your back yard and what do you get? A back yard.
* ShroudedInMyth: Good wizards in fairy tales tend to turn out to be them. At the very least, they're 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 their brilliance, either.
* SniffSniffNom: The Doctor tends to lick things to analyse them; though most seen with 10 and 11, they've 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 they do things like punch through a stone wall or break a rock with their 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, and the Eleventh managed to survive being hit by a ''Dalek laser'', though the Dalek was greatly weakened at the time.
* 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.
** Twelve claims he wears question mark underwear.
* TechnicalPacifist: The Doctor ''really'' puts the "Technical" in Technical Pacifist. Although they have used firearms on occasions, for the most part they are just very good at engineering situations which result in the destruction of their current adversary (sometimes on a ''genocidal'' scale) if that adversary fails to heed their warnings. They also sometimes outsource violence and killing to companions who don't share their hangups, notably Leela, Jack and River.
* TeethClenchedTeamwork: Despite being on the same side, the Doctor and UNIT fall into this. It varies depending on the incarnation, but the Doctor generally disapproves of their military tactics (i.e. "shoot first, ask questions later"), while UNIT barely tolerates the Doctor's arrogant attitude; the Brig and his team and later Kate put up with it, while the other officers don't. It was especially prominent in the Russell T. Davies era, where UNIT's increased aggression against alien threats (justified in the name of [[TheWarOnTerror Homeworld Security]]) was met with nothing less than hatred by the Doctor (''Series/{{Torchwood}}'' shows them in an even darker light, just ask Tosh). The Moffat era reconciled them, but UNIT was still willing to go to extreme measures (like '''nuking London''' to save the rest of the world from an alien invasion). And under Kate's leadership they have a tendency to kidnap the Doctor to ensure their cooperation, since the Doctor's unreliability in such matters is notorious.
* TooCleverByHalf: No Time Lord or Lady is ever afraid of blowing their own trumpet, and the Doctor is no exception. There's a downside to that: every last incarnation has had to spend a lot of time in episodes, serials or series digging themselves out of problems their own occasionally-too-smug intelligence has caused. Sometimes across regenerations.
* TooDumbToLive: Every so often, the Doctor's pacifism sends them into this territory. While their desire to avoid death is understandable, any time the Doctor tries to save long-time enemies such as the Daleks and Cybermen just make people want to slap them. The Doctor themself admits that those species are bred to do nothing but hate and kill, yet the Doctor keeps walking up to them and yelling "Let me save you!", often while they're pointing a gun, laser, etc. at the Doctor's head, usually risking themself, their companion, and ''the world'' in the process.
** Once, when the Tenth 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 the Doctor's enemies blunder into their path and completely fail to understand what the Doctor is capable of. This even applies to enemies who've encountered the Doctor before and ''know'' what the Doctor is capable of, but still don't think the Doctor can stop them. Only the Daleks seem to have the good sense to be afraid of them.
* UndyingLoyalty: They will '''never''' give up on their companions, even if those companions might betray them, intentionally or not. Exemplified to the fullest in their Twelfth incarnation; when asked by Clara ''why'' he would still help her in spite of her betraying him, he responds with probably ''the'' most heartwarming statement in the 50+ years of the program:
-->'''Twelve''': Do you think that I care for you so little, that betraying me would make a difference?
* {{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 their existence ''obvious'' to anyone looking close enough.
** They 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.
* WalkingTheEarth: Suffers from permanent wanderlust.
* 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 they can count, and saved the universe and all of reality itself repeatedly. They defeat intergalactic races of pure evil on a daily basis, think 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 ''their'' long life that they're disheartened by, but the fact that they know that they're forced to watch as their companions grow old and eventually die, all while they remain 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 -- after crash-landing on the planet of Karn, he calls the flame of eternal life the "Flame of Utter Boredom."
* TheWonka: TheCaptain (and one-person crew) of a borderline-magical spaceship who gives strange orders and does strange things that usually tend to work. Throw in a slightly wonky moral compass, a fascination with the strange and terrifying, and [[FriendToAllChildren a soft spot for kids]], and they could pass for the Trope Namer.
* 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. However, after "The Day of the Doctor", the destruction is subverted, and the Twelfth Doctor finally makes it back in the Series 9 finale - only to promptly leave again once he's got what he wanted.
* YouTalkTooMuch: Apparently the difficult thing is to stop them from talking, a criticism which has been leveled at every Doctor at least once!

[[folder:Revival series Doctors (general)]]

->''"[[BadassCreed Never cruel, nor cowardly. Never give up, never give in.]]"''

* {{Adorkable}}: It came and went with Classic Doctors, but it's become permanent after Nine.
** Even the War Doctor engaged in this. His overall personality was grim and applied, but he was nearing the shift toward the adorkable phase. He seemed interested in the fez that fell through the time window, and had a doting grandpa moment when he mistook his future selves for companions. Better yet, he made snappy jokes at his captors. He also grinned like a delighted child when he sonicked the memory controls in the Black Archive because it was probably the first time in that life he got to act like his old self again and make peace instead of war. Overall, War was a very humorous and well-meaning chap. But the icing on the cake was when War started cheering with unadulterated delight when he learned that saving Gallifrey was still possible. And after saving Gallifrey, the last problem he ran into was [[DudeWheresOurCar which TARDIS was his among the other Doctors' police boxes.]]
** The Ninth Doctor, easily the most serious of all the New Doctors, head-bopped to Music/SoftCell in [[Recap/DoctorWhoS27E2TheEndOfTheWorld "The End of the World"]] and had two uncomfortable first attempts at dancing in [[Recap/DoctorWhoS27E10TheDoctorDances "The Doctor Dances"]]. Also the moments of slightly awkward, raw emotional honesty ("I could save the world but lose you."; "You just assume I'm... You just assume I don't... 'dance'.") and the sweet, childlike glee and [[TheKnightsWhoSaySquee fanboyish squee]] he's capable of.
--->'''Ninth Doctor:''' Just this morning you were all tiny and small and made of clay! Now you can expand!
** Ten is easily one of the most Adorkable of all the Doctors, especially when he whips out the PurelyAestheticGlasses.
** Eleven thinks he's much cooler than he really is. See "WHO DA MAN?!" and "Bowties are cool!" Also, his dance moves.
** Twelve seems a bit bashful when on the receiving end of a hug, and keeps up Eleven's dorky dancing.
** Thirteen seems to be just as dorky as Ten, reacting to her new face with a big, ecstatic grin while saying, "Oh, brilliant!"
* AlwaysABiggerFish: Eleven learns that he's known as "The Predator of the Daleks", by the Daleks ''themselves''.
* TheAtoner: Previously, the Doctor saved planets for the fun of it, as well as out of a hazy sense of justice. Prior to "Day of the Doctor", the Doctor was driven to make up for every single death they supposedly caused during the Time War. (See "Deus Angst Machina" below)
* BerserkButton: They HATE Daleks. How much depends on the Doctor: Ten was more willing to forgive, while Nine and Eleven hate them with a passion. Whereas Eleven tries to negotiate/scare them into fleeing (granted, after attacking a tea-bearing Dalek with a spanner), Nine flies into a rage and stays that way, ''literally'' foaming at the mouth. War? They're dead the ''second'' he runs into them... or they run into him. Twelve is closer to Ten: he hates them just as much as his previous selves, but some part of him wants to believe that they can be redeemed.
* BewareTheSuperman: The Doctor has long held themself to trying to avert this trope; part of the reason they have companions is because they keep the Doctor from going too far. But when tragedy leaves the Doctor alone for one reason or another, the revival Doctors can end up having significant breakdowns that result in actions that risk all space and time.
** The Tenth Doctor decides to change a fixed point in history by saving several members of Bowie Base One in "The Waters of Mars" when originally all hands were lost, having decided that -- since as far as he knows there are no more Time Lords -- he is now the "Time Lord Victorious" and a virtual god. Only the suicide of Captain Brooks is able to set history back on its proper, though now sadder, course and cause him to realize MyGodWhatHaveIDone Still, he doesn't accept this as a sign he's been around too long and needs to accept his "death" by regeneration until the denouement of his next and last story, "The End of Time".
** The Twelfth Doctor, in the wake of betrayal and capture by Ashildr and the Time Lords (people he had saved rather than let die/destroy), the death by SenselessSacrifice of his beloved companion Clara Oswald (who had become his DistaffCounterpart along with a LivingEmotionalCrutch), and subsequent lonely torture in his own confession dial under watch of the Time Lords is DrivenToMadness and endures a SelfInflictedHell for billions of years to escape said dial. He emerges as TheUnfettered WoobieDestroyerOfWorlds, willing to defy his people (it doesn't help that the powers-that-be show NoSympathy for his suffering), become a renegade runaway again, ''and'' risk the universe's existence on the TragicDream of saving Clara Oswald from the grave and giving her a "happy", '''safe''' life without memories of him -- an action that again defies a fixed point in time and which he usually tries to ''stop'' others from doing. Clara finally manages to induce a HeelRealization in him and beyond giving her up for good, ends up also losing his key physical and emotional memories of her, unable to recognize her or why he was willing to go so far to save her. As he succumbs to MindRape, he tells her that this is only right and proper because he broke his own rules, and amends his creed to "Never be cruel and never be cowardly, and if you ever are, always make amends."
* BigDamnKiss: Started with Nine's final episode, and has been repeated many times over since then. Ten usually had it happen to him unexpectedly. Eleven actively loves kissing people left and right. Twelve, meanwhile, finally gets a BigDamnKiss with longtime source of FoeYay the Mistress.
* BiTheWay: WordOfGod from both Creator/RussellTDavies and Creator/StevenMoffat have stated that gender doesn't much matter to the Doctor or to Time Lords in general, the latter saying "gender is 'fluid' on Gallifrey". Creator/NeilGaiman confirmed that Time Lords sometimes change sex when they regenerate, which gives some cultural context for the idea, and this eventually gets its first demonstration onscreen in series 8 with the Mistress. Nine and Eleven (who both happily kiss their male companions) are a bit more obvious about it than Ten.
** The idea was carried over from the ''Literature/EighthDoctorAdventures'', in which the Eighth Doctor is blatantly bisexual and spends a lot of time kissing his companions regardless of their gender. ''WebAnimation/ScreamOfTheShalka'', which was supposed to be an official continuation of the classic series, had [[Creator/RichardEGrant a different Ninth Doctor]] and [[Creator/DerekJacobi the Master]] as a couple (though it's subtle enough that Creator/PaulCornell needed to confirm it via WordOfGay). Although Eccleston's Ninth Doctor essentially overrides Grant's, the road was paved for massive amounts of HoYay between the Tenth Doctor and John Simm's Master. (It should be noted that Cornell also intended as unspoken back-story for the Shalka Doctor that he recently lost a wife back on Gallifrey, hence his sour disposition and reluctance to engage emotionally with the android Master or the new companion until right when the serial was about over, so it was easy to miss the nuances.)
* CartwrightCurse: If they offer you the chance to come with them after an adventure, you're (relatively) safe. If they make the offer when you're in the middle of one, you have a very good chance of being a MauveShirt.
-->'''Rory:''' Every time the Doctor gets pally with someone, I feel the urge to notify their next of kin.
* CatchPhrase: "Run!". Nine, Ten, and Eleven all have used this on multiple occasions.
** The Ninth Doctor's first line in the revived series was actually "Run!"
** The Tenth Doctor split this suggestion between his allies and his opponents.
---> '''Doctor''': But in fairness, I'll give you one bit of free advice... Run!
** The Eleventh invokes this when facing the Atraxi.
---> '''Doctor''': I'm the Doctor. [[NamesToRunAwayFromReallyFast Basically... Run!]]
** This evolution from caution to threat is a major part of the Doctor's darkening spiral that leads to several races outright ''fearing'' the Doctor.
*** Avoided with the War Doctor. As the steadfast warrior incarnation, he does ''NOT'' run, since he isn't bound by the same principles of the Doctor to flee.
* TheCowl: On the one hand, the Doctor is a hero who protects children and saves the day. But equally, they do it by being even scarier than the monsters. This process began a bit with the Seventh Doctor's ''[[Literature/DoctorWhoNewAdventures New Adventures]]'' novels and was cemented by Nine's "Oncoming Storm" speech.
* CrazySane: As noted in StepfordSmiler below, Creator/MattSmith believes the Doctor, especially the Eleventh, tends to act absolutely [[CloudCuckoolander bonkers]] simply as a defense mechanism to stop himself from going ''really'' [[SanitySlippage off the deep end]].
* CreepyGood: The Seventh Doctor was already ''plenty'' creepy in the classic series, Eight's [[TranquilFury eerily tranquil moments of anger]] followed by [[RageBreakingPoint frothing outbursts]] in the Big Finish audios made him go from creepy to chilling, and War, Nine, Ten, and Eleven add quite a few more notable moments. War's very presence on a battlefield made a whole Dalek platoon abort a mass extermination to find him because they ''knew'' they were toast if they ignored him (they still got wiped out when the War Doctor brutally ran them down with his TARDIS), Nine scared the bumps off an entire army of Daleks, Ten became intensely scary during "The Waters Of Mars", and Eleven's extremely secretive nature terrifies his companions at times. But Twelve, dear God, ''Twelve''... he scares '''himself''' with his own inner darkness and starts questioning if he's good at all. Then he gets pushed, not of his own choice, off the deep end and over the cliff, and unleashes the seven bells of hell on the Time Lords... It's ''glorious''. '''''Horrifying''''', but '''''glorious'''''.
* DeathSeeker: The first four revival Doctors have been more inclined to self-sacrifice than their predecessors (War had no intention of living through the Time War but the Moment judged that he would live; Nine admitted that he didn't actually choose to survive the end of the Time War). Neither Ten nor Eleven appreciates an outside force telling them YourDaysAreNumbered, but they're still pretty cavalier about their own survival.
** The Ninth has subtle shades of this in his first few appearances; after the Time War, he seems almost gleeful at the prospect of mortal danger.
*** Unless he dies in a dungeon... [[AcceptableTargets in Cardiff.]]
*** His first reaction to a distant scream is to run towards it:
----> '''Doctor''': ''That's'' more like it!
** Ten catches a bit of this after his separation from Rose. Especially in series 4, where he regularly attempts [[HeroicSacrifice heroic sacrifices]] and puts his life in danger. Toward the very end of his life, though, he became very attached to this regeneration and goes to questionable lengths to keep it. Probably because WordOfGod confirmed that Ten only lasted ''nine years'' in-universe. [[note]]Six years, plus three more on Volag-Noc.[[/note]]
** Twelve eventually becomes comfortable with who he is, but his long life as a hero has taken its toll on him, and when his regeneration begins he prefers to go out in a HeroicSacrifice rather than change once again and continue fighting.
* DefeatEqualsExplosion: In a sense, Time Lord regeneration has been [[TakingYouWithMe weaponized]] -- a far cry from the kaleidoscope dirt naps of previous Doctors. The new regeneration effect is a massive buildup and release of energy. War's regeneration was the first to erupt with a flood of energy spouting from his arms and head. When Nine died, he warned Rose to keep at a safe distance, and Ten's expelled radiation and energy blasts caused the TARDIS console room to explode. Eleven received a power-up from Gallifreyan benefactors, giving him enough juice to blast a Dalek fleet to smithereens. Twelve's regeneration also damaged the console room, but it didn't explode... at least until Thirteen tried pressing a button.
* DeusAngstMachina: The War Doctor, when presented with a chance to undo the time lock on Gallifrey and TakeAThirdOption, is given pause once he considers how many lives he ''saved'' because of his guilt over killing his people. He elects to save them anyway -- but the parting of the Doctors will erase each of their memories. This means that once the War Doctor regenerates, he will damn the Ninth, Tenth, and Eleventh Doctors to centuries of guilt for a genocide they ''think'' they caused. "I'll have to live with that."
* DiedStandingUp: All revival series Doctors to date have regenerated whilst standing.
* DudeWheresMyReward: A trait from Ten onwards. Since they've saved the Universe so many times, the least the Universe can do is ensure that their companions aren't taken from them in the most heart-wrenching way possible. Many characters point out that's not how it works.
* FallenAngel: The War Doctor and, to some extent, the [=10th=] Doctor. More to the point, the popularity of handsome, beatific David Tennant coupled with his Doctor's frequent about-faces in morality contributed, in an odd way, to his HazyFeelTurn later on down the line.
* FallingIntoTheCockpit: These Doctors have a bad habit of regenerating while the TARDIS is still in mid-flight. Ten's landing was particularly rocky, bouncing around the streets of Rose's tower block like a pinball. Eleven nearly pitched himself out through the front door, flailed around while the ship hurtled across London's skyline, managed to claw his way back into the console room, fell ''through'' the console room and into the TARDIS' upturned swimming pool, and finally landed in someone's garden... [[ParkingProblems sideways]]. Poor Twelve was struck by an inopportune senior moment when glancing at the controls, leading to the TARDIS being swallowed by a dinosaur(!). Thirteen actually ''was'' pitched out through the front door, leaving her falling through the air as the TARDIS disappeared above her.
** The War Doctor regenerated mid-flight as well, though we don't see the outcome of that one.
* FisherKing: A non-magical example. The War Doctor and his TARDIS become shabby from lack of upkeep, with a dingy, bare-bones TARDIS console cobbled together from scrap, and restoring the original roundels to signal a return to his scientific roots. Nothing too fancy, not even a whole lot of order to where things are placed. In his Ninth and Tenth incarnations, the Doctor begins to flesh out the console room into a coral layout. Though the TARDIS for the Ninth and Tenth Doctors remains basically the same, the TARDIS is lit in a more dark-green way while Nine is still in a dark state of mind from the Time War. After he regenerates, the TARDIS is more brightly-lit, but it arguably gets a lot less inviting as he sulks from postwar trauma, looking shabbier than ever, with exposed wiring, rusty rails, and mechanical groans. Mind you, the Tenth does ''not'' appreciate people calling attention to it (he hits the roof when Wilfred criticizes his housekeeping, and again when War is aghast to see Ten has "let this place go a bit", and Eleven dismisses it all as his counterpart's "[[PostCyberpunk grunge phase]]"). The [=11th=] Doctor finds himself with a new lease on life, and the TARDIS changes into a brightly-lit rumpus room to reflect this frivolity.
** In "The Snowmen" we see that after the loss of Amy and Rory the Doctor has remodeled the TARDIS interior with a darker colour scheme, the decoration has become more spartan and sterile and he's not bothering to turn on the lights. It has ''[[BlatantLies nothing]]'' to do with his depression, [[SarcasmMode seriously!]]
*** But then Twelve comes along following the revelation he has saved Gallifrey and decides the TARDIS needs some elegance and warmth again. He changes the time rotor lighting to an inviting amber and sets up all sorts of shelves and furniture, making the room ''far'' more attractive and pleasant. It's now cozy and padded, taking the best bits from every console room of the series.
* TheFogOfAges:
** Their age was always uncertain in the classic era, largely due to Who's lax attitude to continuity. The new series decided that they honestly can't remember any more and just started counting from "900" at some point.
-->'''War Doctor:''' How old are you now?\\
'''Eleventh Doctor:''' I don't know...I lose track. Twelve hundred and something unless I'm lying. I can't remember if I'm lying about my age, that's how old I am.
** The Twelfth Doctor in particular has trouble remembering all his adventures, even ones that were very emotionally charged at the time. He can remember all of his companions, but specific trips get harder to remember.
* FriendToAllChildren: Every Doctor has a soft spot for children, especially 11. The one thing that haunts the War Doctor is how many children will die if he activates the Moment. Come Twelve's time, though he may be the most abrasive and aloof regeneration of the revival series thus far, even he can still connect with them, as seen in "Listen." Generally speaking, this seems to be the one trait that transcends every shift in personality. Invoked under tragic circumstances in "Face the Raven" when Clara, preparing to meet her death, talks the Doctor down from going on a roaring rampage by reminding him, "Your reign of terror will end with the sight of the first crying child."
* GoingNative: The groundwork was already there in the classic series, but post-Time War Earth really is the closest thing to a home they've got. Ten came close to outright saying this in "Voyage of the Damned"; Twelve basically ''did'' say it in "In the Forest of the Night", referring to Earth as his planet.
* HeelRealization: Has perfected being a TechnicalPacifist, but eventually realizes this ''can be'' much more insidious than simply killing people.
** Twelve in particular has begun questioning his morality, wondering aloud whether he is a 'good man'.
* TheHomewardJourney: Since the epilogue of "Day of the Doctor", the Doctor's been keeping an eye out for the chance to free Gallifrey and its people for good. It's [[FailureIsTheOnlyOption not going too well]]. (Word of Moffat notes that even if/when they do, they'd probably run off again afterwards.)
** Twelve finally makes it back in the Series 9 finale - and promptly runs off again afterwards, as per Moffat.
* HurtingHero: The Time War left very deep emotional scars. In one line of dialog Moffat manages to say everything you need to know about the New Doctor, and it's [[YouRemindMeOfX not even the Doctor who's talking]]: ("The Empty Child")
-->"Before this war I was a father and a grandfather. Now Iím neither. But Iím still a Doctor."
* InsecureLoveInterest: More often than not.
* InternalHomage: So far, each of the revival series Doctors have inherited traits from and taken inspiration from a particular classic series Doctor:
** The War Doctor homages [[Creator/WilliamHartnell Hartnell's]] First Doctor: a curmudgeonly, critical old man who is exasperated by his younger companions, but who has a hidden heart of gold underneath. 1 and War both remarked they were "wearing a bit thin", with One stubbornly putting off regeneration, but War was actually happy about running out his natural body clock.
** Although Eccleston [[http://www.whoviannet.co.uk/info/didyouknow.php is quoted as having watched]] the Fourth Doctor serial [[Recap/DoctorWhoS14E6TheTalonsOfWengChiang "The Talons of Weng-Chiang"]] to prepare for his role, some consider the Ninth Doctor to be a refinement of Creator/ColinBaker's controversial Sixth Doctor: an impatient, sharp-tongued fellow who gradually cools as the audience grows to trust him. Indeed, the 9th Doctor's sojourns to Satellite 5 ([[Recap/DoctorWhoS27E7TheLongGame "The Long Game"]], [[Recap/DoctorWhoS27E12BadWolf "Bad Wolf"]]) are essentially a modernized retelling of [[Recap/DoctorWhoS22E2VengeanceOnVaros "Vengeance on Varos"]] and other politically themed Who stories from the Eighties. In [[Recap/DoctorWhoS27E3TheUnquietDead "The Unquiet Dead"]], he meets and inspires a famed fiction writer from the 19th century, just like Six did in [[Recap/DoctorWhoS22E5Timelash "Timelash"]]. In his sixth adventure, Nine is duped by a distress signal sent from a captive Dalek, similar to the Sixth Doctor's plight in Big Finish's ''Jubilee''. Even Colin Baker himself has commented that the Ninth is the sort of Doctor he wished he'd [[ExecutiveMeddling been allowed to play]]. Colin also said he wished he'd been allowed to dress like Eccleston's Doctor; a dignified black ensemble rather than an eye-melting rainbow suit.
** The Tenth Doctor is most similar to [[Creator/PeterDavison Davison's]] Fifth Doctor, whom David Tennant grew up watching. Both Doctors are the most emotional and human, deadly-accurate with a cricket ball, have bad luck with commuter planes, put glasses on when focusing, broke their sonic screwdrivers, inexplicably wear trainers to accompany their formal wardrobes, semi-frequently encounter the Master, and face [[Recap/DoctorWhoS21E6TheCavesOfAndrozani tragic endings]] to [[Recap/DoctorWhoS30E17E18TheEndOfTime their lives]]. (Most of these traits are lampshaded when the Doctors [[Recap/DoctorWho2007CiNSTimeCrash meet up]].) Davies' [[Recap/DoctorWhoS29E11Utopia "Utopia"]] also owes a debt to [[Recap/DoctorWhoS21E3Frontios "Frontios"]], in which the TARDIS "drifts too far into the future" and discovers a colony of humans struggling to survive on the outer rim. Other obvious homages include [[Recap/DoctorWhoS19E5BlackOrchid "Black Orchid"]]/[[Recap/DoctorWhoS30E7TheUnicornAndTheWasp "The Unicorn and the Wasp"]] (Merchant Ivory whodunnits) and [[Recap/DoctorWhoS20E3MawdrynUndead "Mawdryn Undead"]]/[[Recap/DoctorWhoS28E3SchoolReunion "School Reunion"]] (both set at a boarding school and showcasing a semi-retired companion).
** The Eleventh Doctor greatly resembles Creator/PatrickTroughton, the Second Doctor, right down to the bow tie and awkward, clownish demeanor. Matt Smith's favorite classic Doctor serial is the Second Doctor's [[Recap/DoctorWhoS5E1TheTombOfTheCybermen Tomb of the Cybermen]]. Additionally, the names of their primary companions sound similar (Two had Scottish Jamie and English Zoe, while Eleven had [[GenderFlip Scottish Amy and English Rory]]). Both the Second and the Eleventh Doctors [[Recap/DoctorWhoS5E2TheAbominableSnowmen battled]] [[Recap/DoctorWhoS5E5TheWebOfFear against]] [[Recap/DoctorWho2012CSTheSnowmen the]] [[Recap/DoctorWhoS33E6TheBellsOfSaintJohn Great]] [[Recap/DoctorWhoS33E13TheNameOfTheDoctor Intelligence]]. And then there's his final episode, [[Recap/DoctorWho2013CSTheTimeOfTheDoctor "Time of the Doctor"]], a.k.a. the longest "Base Under Siege" '''ever'''.
** Twelve draws most of his inspiration from [[Creator/JonPertwee Jon Pertwee's]] Third Doctor. This incarnation has even less patience for [[Recap/DoctorWhoS34E6TheCaretaker flatfooted military types]] than he used to, [[Recap/DoctorWhoS11E2InvasionoftheDinosaurs tangles with dinosaurs]], and brooks no disrespect from mortals. His interaction with others seems to flit between gentlemanly charm and sledgehammer-like arrogance (see his banter with Robin Hood and Psi for the best examples), and he's inherited Three's DeadpanSnarker tendencies as well. Clara's blossoming romance with Danny Pink adds to the homage; Twelve meddles with Clara's love life much like Three gloomily looked on as Jo and Cliff sealed the deal or interrupting Jo's planned nights out with Captain Yates. Externally, he wears costumes with jewelry and red inner lining. The most blatant sign of this homage is the fact that Twelve's primary antagonist in his first season is a Delgado/Ainley-inspired new regeneration of [[Recap/DoctorWhoS34E11DarkWater the Master.]]
*** Capaldi's Doctor is somewhat of an homage to the First Doctor, symbolizing a "reboot" of the character's bimillenial lifespan. (The Eleventh Doctor expired once his regeneration cycle was up, whereupon he was given a fresh set of lives by the Time Lords.) This incarnation can no longer be defined as the War Doctor, or the Last of the Time Lords, or the "Oncoming Storm." He's starting from square one: [[HistoryRepeats aged, runaway Time Lord in a TARDIS he doesn't know how to fly, with a companion who teaches at Coal Hill School.]] With the addition of ex-soldier Danny Pink and absentee student Courtney, he has a complete set. (Barbara, Ian, and Susan, respectively.)
* JustFriends: To their companions from Martha onwards. Rose, not quite as much. Clara, not at all. River is also an exception (given that they're ''married''), if you count her as a "companion".
* KidnappedByAnAlly: Kate Stewart has a bad habit of doing this, much to the Doctor's chagrin (they'd rather she'd just ask for help).
* TheKnightsWhoSaySquee: Though Classic Series Doctors loved to name-drop, they were much more low-key about meeting famous people. In "The Unquiet Dead", Nine is practically beside himself upon discovering the horse and carriage he's just hopped into and demanded to "[[FollowThatCar Follow that hearse!]]" belongs to none other than ''Creator/CharlesDickens''. His fanboy squeeing even causes him to briefly forget that he's ''supposed'' to be rescuing Rose! Ten boasts of snogging France's most famous mistress, is excited by the prospect of seeing Creator/WilliamShakespeare perform live for a crowd, and went into major histrionics when he met Captain Adelaide (though it was very much PlayedForDrama); Eleven was reduced to actual incoherent {{squee}} noises when he finally realised who Melody Pond grew up to be. Eleven also really enjoys watching Amy {{squee}} over befriending Creator/VincentVanGogh. Twelve claimed he became a hyper mess after meeting Music/ShirleyBassey.
** Unlike previous Doctors, Ten is fascinated by the whole idea of meeting past and future incarnations of himself, and follows them about like a bad smell. ("Time Crash", "The Next Doctor") Gloriously reversed in the 50th anniversary special: He's already in a foul mood when Eleven turns up, making wisecracks at his torrid love life.
* LargeHam: The Tenth Doctor devours any scenery unfortunate enough to be in his path whenever he's on screen. Then again, it is David Tennant...
* LastOfHisKind: For centuries, the Doctor thought the others were destroyed in the Time War, and sealed in a time lock for good measure.
* LeaningOnTheFourthWall: With the exception of The War Doctor, all of their FamousLastWords can also be taken as the actor expressing their thoughts on leaving the role behind on a meta level.
* LivingForeverIsAwesome: There is more of this in the original series Doctors but the revival Doctors feel it on their better days. The Doctor experiences a lot of heartbreak, but still feels that life is worth living so long as there's something left to see in the Universe. Besides, if they were dead, who would protect the Earth?
* LivingLegend: Known and feared across all of time and space. It's no small thing that the ''Daleks'' refer to the Doctor in their ancient legends as "[[TheDreaded The Oncoming Storm]]" and "[[AlwaysABiggerFish The Predator of the Daleks]]".
** Notable in that by this point, the Doctor has come to realize this and openly use it against their enemies as a way to attempt ending conflicts without actual fighting; ie: make enemy realize they're the Doctor --> enemy runs away/gives up/puts up far less resistance. Eleven found himself on the fast track of learning how much this ''bit him in the ass.''
* LivingRelic: As the [[LastOfHisKind Last Of Their Kind]].
* MadeOfIron: Ten and Eleven seem to possess some great durability, as they are able to withstand attacks to their bodies and not regenerate because of it. For example, Ten was hit by one of the Master's electro beams and was able to go on, while Eleven was hit with a weakened [[OneHitKill Dalek beam]] and ''survived''.
* ManicPixieDreamGirl: They're a madman/woman in a magical box who takes those they meet out of their hum-drum existences to see the wonders of the universe, changing their lives forever.
* MrFanservice: Usually male, and in that context, goes shirtless -- or naked -- with some frequency.
* NewPowersAsThePlotDemands: They know [[MundaneUtility if there's a mole on their back]] and the color of their ''kidneys''! And they can regrow limbs in the first phase of their regeneration cycle, or [[HandWave whatever]]! And they can [[ExpositionBeam relate their entire life story]] by [[UseYourHead head-butting you]]. This is more common in the revival series, where writers have toyed around with the implications of regeneration.
* OutlivingOnesOffspring: Post-Time War, the Doctor's children and grandchildren are all presumed dead. While Clara offhandedly calls them "missing" after the war's outcome is retconned, no mention is made of them when the Doctor returns to Gallifrey in "Hell Bent". Understandably, it's not a subject the Doctor likes to dwell on.
-->'''Amy:''' Doctor, do you have children?\\
'''Doctor:''' No.\\
'''Amy:''' Have you ever ''had'' children?\\
'''Doctor:''' ''(changes the subject)''
* PhraseCatcher: Everyone seems to ask "Doctor Who?". It was used in the classic series as well (in episode 1, even) but became more important after Eccleston and Tennant.
** "Who the hell are you?" has become a frequent hostile first encounter remark in the new series every time the Doctor drops in uninvited-''especially'' if it's a base under siege where nobody from the outside is expected to show up and their sudden appearance is instantly suspicious. And because the TARDIS makes everyone sound like they have a British accent when it translates to what its passengers are accustomed to, it will sound especially caustic, and the person who says this is almost immediately outed as [[TheResenter the angry prick who will be at odds with the Doctor at every turn.]] In other words, when a character asks this to the Doctor, that's how you know they're the {{Jerkass}} of the bunch.
* PopularityPower: The Doctor and their TARDIS seem to grow in power as ratings increase. On two occasions, the Tenth Doctor saved the day thanks to hundreds, if not thousands of people chanting his name ("Last of the Time Lords", "The Next Doctor"), and the TARDIS is now a registered tow truck for planets.
* PrecursorKillers: After the Time War since the Doctor killed everyone in it. Then a temporal paradox makes them a Precusor ''savior'' that thinks themself to be a killer.
* RunningGag: A few.
** Ten and Eleven are both disappointed they're not ginger post-regeneration. [[Literature/DoctorWhoNovelisations The novelisations]] let the others get in on it as well: Eight privately wonders if the Sisterhood could make him ginger in the "The Day of the Doctor" novelisation, Nine's examination of his face in the "Rose" novelisation has him wondering why he's never ginger, and Twelve reflects in the "Twice Upon a Time" novelisation that given his luck his next self's probably not going to be ginger.
** On a similar note, the Doctors get self-deprecating over some part of their new bodies post-regeneration (Nine his ears, Ten his teeth, Eleven his chin and hair, Twelve his kidneys(!) and eyebrows). Thirteen doesn't seem to mind being a woman, but seeing as how she's barely had time to react to her new body yet, we'll see how this goes.
*** Also, the Doctor has a tendency to regenerate in the TARDIS and get in trouble because of it. In particular, Eleven and Thirteen's respective predecessors destroy the console as they regenerate, causing it to crash in flames as it hurtles towards Britain. While Eleven is left hanging, Thirteen is immediately flung out.
** The Doctor's relationship with Queen Elizabeth I, as referenced in "The Shakespeare Code", "The End of Time", "The Beast Below", "Amy's Choice", "The Wedding of River Song", and "The Name of the Doctor". Particular attention is drawn to her nickname, and how she "cannot use it anymore". (Interestingly, people always think of the nickname "The Virgin Queen", which points to an obvious conclusion, but the nickname the Doctor actually cites is the much less specific "Good Queen Bess".)
* SadClown: Ten and Eleven, in particular, keep up a bit of an act. The act is dropped with Twelve, however, who no longer hides behind silliness ... except on those occasions in which he does.
* ScrewTheRulesImDoingWhatsRight: Often combined with ScrewDestiny and TakeAThirdOption. Perhaps the most magnificent example occurs in the 50th anniversary special, when the War, Tenth and Eleventh Doctors call the War Council of Gallifrey and assure them that they'll do [[RedemptionQuest everything they can to save the planet and its commoners]], [[ScienceHero without so much as firing a shot]]. While the members of the council admire the bravery and resolve of the Doctors, they question the technical feasibility of the idea, and especially the reasoning. Cue the following lines from the Tenth and Eleventh Doctor:
--> '''Eleventh Doctor''': Because the alternative is [[EarthShatteringKaboom burning]]...
--> '''Tenth Doctor''': ...and [[HeroicBSOD I've seen]] [[MyGodWhatHaveIDone that]]...
--> '''Eleventh Doctor''': ...and [[BadassBoast I never want to see it again!]]
* ShippingTorpedo: The trope is {{played for laughs}} whenever Captain Jack Harkness is around, given that Jack is a LovableSexManiac and an ExtremeOmnisexual. It became a RunningGag that the Doctor (both Nine and Ten) would torpedo Jack's attempts at flirting with, well, everyone.
* ShipTease: While the Doctor's only explicit, onscreen romances are with River Song and a few one episode companions like [[Recap/DoctorWho2007CSVoyageoftheDamned Astrid]] and [[Recap/DoctorWhoS28E4TheGirlintheFireplace Reinette]], there are varying levels of sexual tension with almost every companion. Everyone but Mickey and Sarah Jane gets at least one kiss. Donna, the epitome of JustFriends, does it because the Doctor needs a shock. The relationships with Rose and Clara are also romantic in nature (per WordOfGod and watching the episodes themselves as they deliver the message with the subtlety of a sledgehammer), however due to TheILoveYouStigma it's possible to interpret even these relationships as being no more than friendships (despite both characters saying "I love you" directly at the Doctor).
* StepfordSmiler: A constant with each of the new Doctors. Eleven went so far as to manifest his subconscious, who proceeded to mock his new TARDIS decor, cockamamie outfit and mid-life crisis.
* SuperCellReception: Some Doctors occasionally use the Sonic Screwdriver or other alien tech to give a phone Universal Roaming, allowing it to make a call from anywhere, anywhen to anywhere, anywhen. Without any special dialling code or anything. Only interference either from Satan or the nearby black hole in "The Impossible Planet" is able to put it out of range.
* SurvivorGuilt: The Ninth Doctor left the Time War with a ThousandYardStare. The Tenth and Eleventh also suffer this on occasion, the Tenth in particular after the loss of Rose and River Song but it likely hits him harder as Eleven, and the Eleventh after Rory dies in Season 5 and especially after both Rory AND Amy die (so to speak) in Season 7.
* TerrorHero: The War Doctor simply had to ''appear'' on a battlefield to get his enemies running scared in "The Day of the Doctor". And not long after he had regenerated, the Ninth Doctor held onto that threatening presence in "Rose". It made the Nestene Conciousness freak out because it knew what the Doctor was like during the Time War, which only just ended. The Doctor, fresh out of that war, was stewing with anger and wrath that magnified his menacing qualities even further. Later on, the Tenth and Eleventh Doctors both used their reputation to scare off the Vashta Nerada in "Forest of the Dead" and the Atraxi in "The Eleventh Hour" respectively. Finally, in "Deep Breath", the Twelfth Doctor could terrify an emotion-lacking android into acknowledging the human feelings it had acquired by defeating its own logic, or merely freak out a vagabond by acting crazy and just on the sheer scare factor of his scowling face!
* TrademarkFavoriteFood: Bananas have been popular with Nine ("Bananas are good!"), Ten ("I think I just invented the Banana Daiquiri!") and Eleven, and all three use the fruit to distract overly gun-happy people with. (This was notably also a favorite tactic of the Eighth Doctor in the novels, before the revival series started. He'd run up to a guard, wielding a banana, and yell "bangbangbangbangbang!" while his companion stole the confused guard's gun.)
* WhereIWasBornAndRazed: By the end of the Time War, the conflict had become so unmanageable that the only way out was to destroy ''everything'', either via Rassilon's plan to collapse time into itself -- thereby elevating the Time Lords to incorporeal gods -- or trapping the planet inside a moment in time, effectively ziploc-bagging the war in perpetuity. The Doctor opted for the latter, leaving them the last Time Lord still alive. Rassilon managed to FlingALightIntoTheFuture in an attempt to revive their homeworld, but as that would also bring back the nightmarish hordes still fighting the war, the Doctor (with help from [[EvenEvilHasStandards the Master]]) put the kibosh on that pretty quick. Thankfully, while the war is still sealed off, Gallifrey survives at the end of the universe; the Daleks destroyed themselves in their own crossfire.
-->'''The Doctor:''' You weren't there. In the final days of the war. You never saw what was born. But if the time lock's broken then ''everything'' is coming through. Not just the Daleks, but the Skaro Degradations, the Horde of Travesties, the Nightmare Child. The Could-Have-Been King with his army of Meanwhiles and Neverweres. The war turned into hell! And that's what youíve opened. [[{{Hellgate}} Right above the Earth]].
* WhoWantsToLiveForever: Nu Who's Doctor appears tired of their lonely, blood-soaked existence and actively suicidal at times (especially Ten), but also desperately runs from "death" when his time seems to be up. Part of it is the Doctor's not-entirely-false suspicion that a little knowledge is a dangerous thing, and that Time Lords are too powerful and dangerous to be trusted with immortality.
* YouShallNotPass: Many, many notable episodes. The Ninth Doctor held off the Dalek Emperor and his half-crazed legion of hybrids until he was literally the last man standing. (Cap. Jack went out like a champ, but was soon brought back via the time vortex.) The Tenth Doctor held his own war-mongering President at gunpoint rather than allow him to set foot on Earth. Eleven once shook fists at ''all'' of the Doctor's accumulated enemies and dared them to try and take the Pandorica away from him, and then he did it ''again'' on Trenzalore.

!Minor Incarnations
[[folder:The "Meta-Crisis" Tenth Doctor]]
!!The "Meta-Crisis" Tenth Doctor
->'''Played by:''' Creator/DavidTennant (2008)

-->''"I'm part human. Specifically, the aging part. I'll grow old and never regenerate. I've only got one life, Rose Tyler. I could spend it with you, if you want."''

An unusual tangent from the Doctor we know as a side effect of his sidestepped eleventh regeneration. He was the final result of the original Doctor losing his hand in a Sycorax duel, which Jack rescued and returned to him. The Doctor kept it with him until a Dalek got in a cheap shot and made him regenerate. The Doctor, having a vain streak at the time, cheated the regeneration and used his severed hand as a container for the energy that would recreate his body. This in fact counted as far as his allotted regenerations went, leaving the Doctor with [[Characters/DoctorWhoEleventhDoctor one last regeneration]] in his first cycle.

Donna Noble interacted with the hand while it was coursing with regeneration energy that tried to heal the limb as though it was still a part of its Time Lord owner, but didn't have enough DNA to recognize the full picture of the Doctor's body. Donna's DNA got sampled and used to fill in the gaps, causing the hand to sprout into a whole new Doctor with a bit of Donna's temper inside him. He picked up her human body, leaving him a Time Lord brought down to human level- what he called a "biological meta-crisis." It led this clone to choose a different path from the Doctor, reciprocate his love for Rose Tyler in his stead, and live a happy life in a parallel universe with her.

However, the original Doctor also noticed the clone resembled his attitude right after coming out of the Time War, like the Ninth Doctor before mellowing out, and less qualms about killing his enemies. He left Meta-Crisis Ten in her care to help him overcome these dangerous qualities and satisfy her love for him that he couldn't provide as a Time Lord.

* BigDamnKiss: Shares a very passionate one with Rose when he reveals that he really loves her, which the Tenth Doctor could not say, because Rose would never leave his side and he would outlive her.
* ChekhovsBoomerang:
** The Doctor's hand was involved in a great deal of important events before it finally turned into him.
** The regeneration used to create him becomes important later on in [[Recap/DoctorWho2013CSTheTimeOfTheDoctor "The Time of the Doctor"]], when it turns out that, because of this, the Eleventh Doctor is actually the thirteenth and the last regeneration of his first cycle.
* CloningBlues: Averted. He has no angst at all over being a clone. He doesn't even care that he's half human. Nor does he have "I'm not real!" sort of blues. "I ''am'' the Doctor."
* CompositeCharacter: Wears Ten's suit and shoes, has Donna's characteristics stacked against Ten's, and resembles Nine, also wearing a plain, collar-less shirt without buttons or a tie to go with it, similar to Nine's habit of wearing stripped down attire and simple V-neck sweaters.
* DarkerAndEdgier: With respect to the Tenth Doctor he's much more unhinged and ''definitely'' less apprehensive about murder.
* IDidWhatIHadToDo: The Daleks had nearly destroyed the Universe, and if he left them around, even without a reality bomb they could ''still'' destroy the cosmos. He explictly points this out before flipping the switch.
* DoppelgangerReplacementLoveInterest: Not only does he look just like Ten, he has all of Ten's memories, experiences, thoughts and feelings.
* FanficMagnet: For Rose x Ten shippers.
* {{Fanservice}}: Born from an unclothed hand, he's naked right off the bat when it grows into a complete body.
* HalfHumanHybrid: Part Human part Time Lord.
* HappilyEverAfter: With Rose in exchange for the original Ten because he gets to grow old with the woman he loves.
* HotBlooded: Being created with help of Donna's DNA gave him this. Unlike the Doctor, he doesn't hesitate to obliterate a Dalek fleet with the flick of a switch.
* LoveConfession: Implied and confirmed to tell Rose "I love you" in an inaudible whisper in her ear, triggering a kiss.
* MixAndMatchMan: He's an ArtificialHuman clone of the Tenth Doctor created from the combined DNA of him and Donna Noble.
* NakedOnArrival:
-->'''Donna:''' It's you! \\
'''Meta-Ten:''' Oh, yes! \\
'''Donna:''' ... You're naked. \\
'''Meta-Ten:''' Oh, ''[[CaptainObvious yes]].''
* OtherMeAnnoysMe: Ten makes it very clear his clone's creation was against his wishes after seeing him off millions of Daleks with the flick of a switch. This hits way too close to home and Ten is ''furious''.
-->'''Ten:''' Because we saved the universe, but at a cost. And the cost is ''him.'' He destroyed the Daleks. He committed genocide. He's too dangerous to be left on his own.\\
'''Meta-Ten:''' ''[accusingly]'' You ''made'' me.\\
'''Ten:''' Exactly. You were born in battle, full of blood and anger and revenge. Remind you of someone? That's me, when we first met. And you made me better. Now you can do the same for him.\\
'''Rose:''' But he's not you.\\
'''Ten:''' He needs you. That's ''very'' me.
* TheSlowPath: One reason Ten left the Meta-Crisis Doctor with Rose; no advanced age or regenerations and no TARDIS.
* TheUnfettered: The ''other'' reason Ten left his clone with Rose. He '''''casually''''' ''committed genocide on the Daleks''. While Ten had his own moral code and wouldn't resort to killing unless it was absolutely necessary, Meta-Crisis immediately acted to blow the Daleks up. This scared Ten into wondering just how much terror he could bring to the universe if someone didn't reform him, so he decided Rose could do the trick.

[[folder:"The Curator"]]
!! "The Curator"
->'''Played by:''' Creator/TomBaker (2013)

-->''"I'm only a humble curator, I'm sure I wouldn't know."''

From what is suggested on-screen, the Curator may be a much, much older incarnation of the Doctor following many regenerations. He chose to retire from his adventures through time and space, and become the curator of the National Gallery. He looks suspiciously familiar. (The Titan Comics expanded universe has since confirmed that the Curator ''is'' a future incarnation of the Doctor.)

* BlatantLies: While he [[AmbiguousSituation skirts around]] the question of being a future incarnation of the Doctor and even claims ''not'' to be at one point, the Eleventh Doctor doesn't doubt that he's speaking to [[MyFutureSelfAndMe his future self]] for a second.
* CoolOldGuy: A very old man who may or may not be the Doctor and who's still as affable as ever.
* CrypticConversation: Again, he implies that he's one of The Doctor's regenerations but at the same time doesn't give anything definitive.
* IconicOutfit: Averted, but ''not'': even though he's "revisiting the old favorites" in terms of faces, he's seen without Tom Baker's trademark scarf. WordOfGod has it that he gave it to Osgood.
* LeaningOnTheFourthWall: Conversation with the 11th Doctor doubles as Creator/TomBaker congratulating Creator/MattSmith on becoming one of his successors in the role of the Doctor. This ties into the end of ''Series/AnAdventureInSpaceAndTime'', where Creator/MattSmith appears (in character) and meets Creator/WilliamHartnell.
* MeaningfulName: In Latin, the name ''Curator'' stems from the verb ''curare'', which means ''to take care of'' or ''to cure''. In other words... a Doctor by yet another name.
* NoNameGiven: Just "The Curator".
* RetiredBadass: Gave up saving the universe and settled down to become a simple museum curator on Earth. Just as Eleven mused he could do one day.
* SequelHook: He tells Eleven that Gallifrey was saved in "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]", and encourages the Doctor to look for it. Which leads into the MythArc of Series 8 and 9.
** Mentions that the Doctor may revisit familiar faces in the future, something that technology is slowly allowing as an option.
* ShroudedInMyth: The whole existence of the Curator is basically an enigmatic tease that the Doctor is going to live a very long life and eventually end up going into retirement... [[TenMinuteRetirement and not just for a short amount of time]], but for real. The presence of a work of art in the background of his scene that looks identical to TARDIS roundels has also got people speculating that this is a clever hint that the museum is in fact the interior of the Curator's TARDIS- but then again, it could just be a meaningful selection to hang in the museum by the Curator because the Doctor loves the "round things", and at the very least, the sculpture strongly hints at the presence of the Doctor being the one actually overseeing the museum all along.
* YouLookFamiliar: [[invoked]] He has gone through enough regenerations that he started "revisiting old faces" (but only the favorites!). In this case, he looks like an older Fourth Doctor.
--> '''Eleven''': I never forget a face.\\
'''Curator:''' Oh, I know you don't. And in years to come, you might find yourself... revisiting a few. But just the old favorites.
* VisualPun: Who knows? Who... [[GagNose nose]].
* WhamLine: His introduction, startling the Eleventh Doctor with the same voice and features as his fourth incarnation.
--> '''Eleven:''' I could retire and become the curator of this place.\\
'''Curator:''' You know, I really think you ''might''.
* WhamShot: When he shows his face, both Eleven and fans know that he is the Doctor because he's played by Tom Baker.
