[[folder: "Susan Foreman"]]
!!Arkytoir AKA "Susan Foreman" (First Doctor)
->'''Debut:''' "[[Recap/DoctorWhoS1E1AnUnearthlyChild An Unearthly Child]]" (1963)
->'''Departure Story:''' "[[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth The Dalek Invasion of Earth]]" (1964)

->'''Played by:''' Creator/CaroleAnnFord (196364, 1983, 1993)

-->''"Oh, grandfather!"''

The Doctor's granddaughter. When the series began, she attended Coal Hill School in London as a student for a few months in 1963, posing as a human with a fake human name. She's ConstantlyCurious and extremely sweet. Returns much later, with at least the appearance of an adult, to help out the first five incarnations of her grandfather all at the same time.

* {{Adorkable}}: Certainly has her moments of this.
* AlienAmongUs: Is one, who was trying to pass herself off as a regular human student when attending Coal Hill School.
* BewareTheNiceOnes: Her response to cavemen kidnapping her grandfather was to jump on the back of one and start attacking him. Granted, she didn't succeed in defeating him but right there it was established she will resort to violence if pushed too far.
* BrainyBrunette: Dark haired and very intelligent.
* BoundAndGagged: In "[[Recap/DoctorWhoS1E5TheKeysOfMarinus The Keys of Marinus]]" Episode 6.
* TheBusCameBack: While Susan has certainly been on a LongBusTrip, she did return for one adventure in 1983. To this date, Carole Ann Ford is ''still'' playing Susan in the Audioplay/BigFinishDoctorWho audios, both in First Doctor stories and as a companion to the Eighth Doctor.
* BusCrash: The Doctor stated he was the LastOfHisKind as early as "[[Recap/DoctorWhoS30E17E18TheEndOfTime The End of Time]]". In the later episodes "[[Recap/DoctorWhoS27E9TheEmptyChild The Empty Child]]", "[[Recap/DoctorWhoS28E11FearHer Fear Her]]" and "[[Recap/DoctorWhoS30E6TheDoctorsDaughter The Doctor's Daughter]]", the Doctor reminisces about having had children once, and confirms that he considers every last Time Lord dead.
** Possibly subverted if the only reason the Doctor thought he was the LastOfHisKind is because Susan was on Gallifrey at the end of the Time War, with her having been confirmed now to have been there in a recent Big Finish release. If that's the case, now that it's been [[TheReveal revealed]] that the Doctor managed to save Gallifrey in a frozen moment in time rather than destroying it it's possible that Susan's still alive.
* TheCameo: She's ''very'' briefly seen, from the back, in a flashback in "[[Recap/DoctorWhoS33E13TheNameOfTheDoctor The Name of the Doctor]]". Her photo also appears on the Doctor's desk in "[[Recap/DoctorWhoS36E1ThePilot The Pilot]]".
* ButNowIMustGo: Big Finish shows her deciding it's time to leave Earth in order to assist her people in the Time War.
* CategoryTraitor: Has become this by leaving Gallifrey and breaking the non-interference clause with her Grandfather. The EU indicates the Doctor fearing repercussions for this played a role in him leaving her behind on a "safe" Earth.
* CheerfulChild: She has a tendency to act younger than her apparent age, probably because she is ''extremely'' young by Time Lord standards, and can't resist a giggle even at the most inappropriate times. For example, she laughs at the way one of her Dalek captors says her name in "[[Recap/DoctorWhoS1E2TheDaleks The Daleks]]".
* CloudCuckoolander: Her odder moments of behavior, or when her behavior changes (as noted bellow), could be explained as this.
* TheConscience: Serves as this to her grandfather.
* ConstantlyCurious: She is full of questions.
* CuddleBug: Loves to cling to people, especially Barbara and her grandfather.
* CuteClumsyGirl: One infamous moment has her accidentally dropping a bridge on top of the TARDIS ''and'' twisting her ankle in the process.
* DancingWithMyself: Demonstrated to do so in an "Unearthly Child" albeit...somewhat oddly.
* DependingOnTheWriter: She was originally intended as a CreepyGood ActionGirl with PsychicPowers but was [[{{Retool}} Retooled]] into a "normal girl" after the unaired pilot. The result of this is that her character fluctuates wildly between scripts: in "An Unearthly Child" she is a nice girl who wishes she was normal but shows a little NightmareFetishist behavior ("I like walking through the dark. It's mysterious.") and physically attacks a massive, armed caveman to save her friends; in "The Daleks" she is a KiddieKid who displays exaggerated fear about walking through the dark and the few times she's allowed to speak it's to make stupid suggestions ("First we all lie down and pretend to be dead..."); in "The Edge of Destruction" she drifts around in a long dress, babbles about creatures inside her and threatens to shred Ian with a pair of surgical scissors; in "Marco Polo" she is a TotallyRadical sixties teen who thinks everything is "gear"; in "The Keys of Marinus" she is a DistressedDamsel; in "The Aztecs" she has nothing to do; in "The Sensorites" she has a fight with her grandfather and saves the day with her telepathic powers; and then in "The Reign of Terror" she refuses to attempt to escape from a prison when she and Barbara are due to be guillotined because she's scared of the rats, and then develops a fever for plot convenience.
** Whether or not Susan should be described as a Time Lord herself (as in a member of the Time Lord Race) or a Gallifreyan is up to debate. Onscreen, it has been arguably suggested that not all Gallifreyans are necessarily Time Lords and that Time Lords are an elite society which one must join and be indoctrinated into (including the Time Lord Academy). Being that Susan was depicted as a teenager, there is little evidence that she had already done this. Her demonstrated superior knowledge of science had been explicitly mentioned to be normal for children of her planet, so that wasn't an indication of Time Lord education, although the age of enrollment being 8 means she could have been in the school for a while, if not perhaps graduated.
* DistressedDamsel: Her young age likely didn't help her to avoid being in situations like this.
* EarlyInstallmentWeirdness:
** She has a human name, although later established to be an alias; her real name being Arkytoir.
** Susan claims she invented the acronym "TARDIS". Later, all Time Lords call the machines by that name, although it's possible she only thought she'd created it.
** She's the only confirmed blood relation of the Doctor's to have appeared, except from [[OppositeSexClone Jenny]], with the Doctor's MysteriousPast meaning that not much more is known about the family tree.
** She departs the TARDIS to marry a human. Time Lords' incredibly long life spans had yet to be established by that point, so the inevitability of Susan outliving her teenage love by several millennia isn't brought up.
* FishOutOfTemporalWater: Clearly doesn't know how 20th century human teenagers are supposed to act, or even the currency system used at the time and sticks out like a sore thumb at school because of it.
* GallowsHumour: Has moments of this, such as laughing at a Dalek.
* HumanAliens: From the same race as the Doctor, which initially the audience knew nothing about, not even their name.
* JumpedAtTheCall: When the Time Lords ask for her help in fighting a very particular war.
* ImmortalityBeginsAt20: More like mid/late teens but the EU clarifies that her apparently older appearance when she's seen again is a disguise. She hasn't biologically aged in decades. This is a species trait.
* TheIngenue: Much more optimistic and trustworthy than her grandfather, especially when they first arrive on Earth.
* ItRunsInTheFamily: It's very clear that she's her grandfather's granddaughter.
* KidAppealCharacter: Basically this.
* LongBusTrip: Returns in the 20th anniversary special "The Five Doctors", and in the [[AudioPlay/BigFinishDoctorWho Big Finish Eighth Doctor audio]] "An Earthly Child" and subsequent stories.
* MamaBear: The EU establishes that she becomes so after being left on Earth with David.
* MemeticMutation: When established to like memes in an audio, her meme love itself became somewhat of a minor version of this on the internet.
* MoralityPet: Before the Doctor's CharacterDevelopment, he rarely shows concern for anyone besides Susan.
* MysteriousPast: It's unknown why she and the Doctor left Gallifrey.
* NiceGirl: Creates a stark contrast to her much more ill-tempered grandfather, especially in his earliest stories. She warms up to Earth and humans much faster than him.
* NightmareFetishist: When she isn't scared enough to feel in danger, she certainly is this, with her voicing a love of the dark and her excitement at fighting a caveman and the prospect of using burning skulls to chase more off. Her reaction to finding a sacrificial knife is also to pretend to use it on herself.
* NoodleIncident: The 11th Doctor mentions a visit to the Rings of Akhaten with her, but what exactly happened during it is unknown.
* ObfuscatingStupidity: Tries this when in Coal Hill Academy but her tendency to blurt things out limits the success of this and Ian even says he suspects she's smarter than she lets on.
* OutlivingOnesOffspring: Used to have offspring but conflict with the daleks on Earth resulted in that not being the case anymore.
* PstandardPsychicPstance: In "[[Recap/DoctorWhoS1E7TheSensorites The Sensorites]]".
* PsychicPowers: She's very gifted in telepathy, ''much'' more so than the average Time Lord, including her grandfather.
* PutOnABus: Done at the end of the serial "[[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth The Dalek Invasion of Earth]]" where the Doctor leaves her behind so she can marry a nice young resistance fighter and have [[HomeSweetHome some stability in her life]]. She would have stayed with her grandfather out of a sense of obligation if he hadn't. She returns in "The Five Doctors".
* RiddleForTheAges: Susan's real (Gallifreyan) name. According to the short story ''Roses'', it is Arkytior, High Gallifreyan for "Rose". One wonders if the reason the revival series Doctor picked his first companion was based on this.
* ScreamingWoman: Justified in the case of Susan; she's incredibly sheltered and repeatedly shown to be nervous and easily intimidated, and has been raised by the Doctor to view the outside world as an inherent threat. And, of course, she's also a child; younger by Gallifreyan standards than human ones, and even a shy human teenager could be forgiven for screaming while being kidnapped by cavemen. As it is, when older she [[TookALevelInBadass is a lot more capable of fending for herself.]]
** It could be argued that applying this trope to Susan is unfair; she screams quite often, but is also shown to be remarkably intelligent, perceptive, and generally a very useful person to have around. She just gets excited from time to time.
* SecurityCling: She's very frequently clinging to either Barbara or the Doctor.
* ShelteredAristocrat: As a very sheltered member of the Time Lords, the aristocrats of the universe.
* ShipperOnDeck: The Creator/BigFinish Companion Chronicle "Here There Be Monsters" opens with her talking about how she thinks that Ian and Barbara truly belong together. (The Franchise/DoctorWhoExpandedUniverse agrees unanimously with her, and a reference in the "Death of the Doctor" episode of ''Series/TheSarahJaneAdventures'' made it official for TV continuity.)
* SquishyWizard: While she posses abnormally strong psychic abilities, physically she cannot put up much of a fight.
* TheCallKnowsWhereYouLive: Big Finish shows that the Time Lords always knew exactly where she really was, and thus when the Time War rolled around they could send the call.
* TheHeart: Always wants to do her best to help.
* TookALevelInBadass: Her older-self definitely did, becoming much more competent and even a member of the fledgling 22nd century human government.
* TeenGenius: Being from the highly advanced civilisation of Gallifrey, this is a given, to the extent where she has to hold back when pretending to be a human student on Earth. Her astounding knowledge is the main reason Ian and Barbara become curious about her in the first place.
* ThickerThanWater: She feels strongly about her duty to her grandfather.
* TotallyRadical: '60s version. Apparently she picked up some of the local youth lingo during her time in Coal Hill.
* TheWoobie: From having to flee her home planet for reasons her own grandfather refuses to tell her, to then being left behind by him on Earth...and things only get worse for her from there on.
* UndyingLoyalty: Mostly to her grandfather, but she will also refuse to leave other allies in trouble and consequently have to be physically dragged off so that she does.
* WhatHappenedToTheMouse: While the Doctor believing himself to be the LastOfHisKind suggests he may have believed her to have been on Gallifry and involved, exactly what she was up to during in the Time War other is currently unknown. She's been confirmed to having been a participant but that is all.
* WhatTheHellHero: Has called out the Doctor for some of his more morally questionable actions.
* TheWorldIsJustAwesome: Has this opinion of Earth and seems to have it of her home planet too when reminiscing in The Sensorites.
* YouCantGoHomeAgain: As the Doctor says, they are exiles from their own people. The EU even clarifies that Susan herself doesn't known why this is. It takes the Time War for her to go back.
* YoungerThanTheyLook. Later becomes a complicated example of this trope, as after 30 years on Earth she has ''disguised'' herself to look like how she ''should'' at that age, were she a human, with her really still looking like a teenager. It's only therefore by Time Lord standards that this disguised appearance counts, as in actuality it would take centuries at least for her to genuinely appear that age.

[[folder: Barbara Wright]]
!!Barbara Wright (First Doctor)

->'''Debut:''' "[[Recap/DoctorWhoS1E1AnUnearthlyChild An Unearthly Child]]" (1963)
->'''Departure Story:''' "[[Recap/DoctorWhoS2E8TheChase The Chase]]" (1965)

->'''Played by:''' Jacqueline Hill (196365)

-->''"Accuse us? You ought to go down on your hands and knees and thank us! But gratitude's the last thing you'll ever have, or any sort of common sense either."''

A history teacher at Susan's school who, together with Ian, gets abducted by the Doctor. A very down-to-earth companion who freely spoke her mind and never put up with the Doctor's lies and secrets. Quickly became a MemeticBadass for how determined she was in defeating monsters with whatever tools she had available.

* AbhorrentAdmirer: Barbara got chased by very unsavory types a few times, and on one occasion, was offered freedom in exchange for you-know-what. She was decidedly ''not'' impressed with the offer.
* ActionGirl: Running over a Dalek with a ''truck''.
* TheAgeless: In "[[Recap/TheSarahJaneAdventuresS4E5E6DeathOfTheDoctor Death of the Doctor]]" on ''Series/TheSarahJaneAdventures'', Sarah Jane, after doing research to find other old companions of the Doctor, says that Ian and Barbara, now married and professors at Cambridge, are said not to have aged since the 1960s.
* BadassNormal: Barbara ran over Daleks ''with a'' '''''lorry'''''. The series' [[Awesome/DoctorWho Moment of Awesome]] page put it best: "The first two seasons could have been renamed The Why Barbara Is Awesome Show, and no one would have noticed."
* BadassTeacher: Both she and Ian, [[MoreDeadlyThanTheMale with Barbara being the bigger Bad Ass of the two.]]
* BigDamnKiss: Barbara doesn't waste any time in becoming the first person in ''Series/DoctorWho'' to snog someone: a handsome young Thal on Skaro.
* BoundAndGagged: In "[[Recap/DoctorWhoS2E6TheCrusade The Crusade]]", in Episode 1.
* BrainyBrunette: She can understand the TARDIS better than the Doctor can, at times. (In one Magazine/DoctorWhoMagazine comic, Eleven even calls her a "beautiful, bouffanted ''brainbox''".)
* TheBusCameBack: Both she and Ian make a surprise appearance the 50th anniversary comic book, "Hunters of the Burning Stone".
* {{Chickification}}: While she spends most of her time being confused and screaming in her first episode, this is {{Justified}} by the circumstances of her companionship, and she soon gets some CharacterDevelopment and becomes TheHero of several stories (notably Part 2 and 3 of "[[Recap/DoctorWhoS1E5TheKeysOfMarinus The Keys of Marinus]]" and "[[Recap/DoctorWhoS1E6TheAztecs The Aztecs]]"). In stories where she has a more backseat role, it tends to be a more dynamic one (such as journeying with a Thal war band in "[[Recap/DoctorWhoS1E2TheDaleks The Daleks]]", and going on an expedition to defeat the Daleks in "[[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth The Dalek Invasion of Earth]]"). In both "The Dalek Invasion of Earth" and "[[Recap/DoctorWhoS2E3TheRescue The Rescue]]" she is shown to be willing to kill in order to protect younger female characters with her. However, after Susan, the DamselInDistress in most of her stories, leaves, she's replaced with SuspiciouslySimilarSubstitute surrogate-granddaughter Vicki, a more energetic and optimistic character who tended to be paired off with the Doctor so they could go on VagabondBuddies-type adventures as a comical [[TwoLinesNoWaiting B Story]]. Since Vicki was ineligible to be the Damsel, the role got handed over to Barbara, who then started getting captured, hypnotised, sold into slavery, and threatened with rape a lot more often. A plot point in "[[Recap/DoctorWhoS2E6TheCrusade The Crusade]]" even centres around her supposed unwillingness to kill, even to protect a young female character with her.
* DamselInDistress: She alternately played this trope straight and subverted it. The most memorable straight example would be in "An Unearthly Child", where she spends most of the last two episodes screaming and crying. She seems to have gotten it out of her system by the next serial, where she's perfectly happy to go on a commando raid into the Dalek city. Her most memorable subversion is probably "The Crusade", where she does get kidnapped, but rescues herself and is on her way back to rescue everyone else by the time Ian shows up to save her.
* DeadUnicornTrope: When ill-informed media commentators or post-2005-only fans claim that all pre-2005 female companions were just [[TheLoad useless]] [[ScreamingWoman screaming]] [[MsFanservice eye-candy]], the show's defenders can point to one of the very first ones.
* DefiantCaptive: Barbara is ''hardly'' passive in captivity. Her immediate reaction to hostile monsters is to bash their heads in.
* AGodAmI: Comes off as this in "[[Recap/DoctorWhoS1E6TheAztecs The Aztecs]]", although she clearly knows that she isn't one. Attempting to change history and calling yourself an Aztec god (ItMakesSenseInContext) will do that.
* GodGuise: In "[[Recap/DoctorWhoS1E6TheAztecs The Aztecs]]", she gets mistaken for the Aztec deity Yetaxa and tries to use her position to change the Aztec Empire.
* GoodIsNotSoft: Barbara becomes less pacifist as the series continues.
* KleptomaniacHero: Notably in "The Aztecs". Her love of history doesn't prevent her from trying on shiny things she finds in graves.
* MamaBear: Very protective of Susan and later Vicki.
* MoralityChain: Barbara has no problems with telling the Doctor where to stuff his "angry old git" act. He mellows out ''considerably'' around her.
* MrExposition: On most occasions that the team find themselves in Earth's past, Barbara, true to her profession, gives an impromptu history lesson.
* MurderIsTheBestSolution: Usually played straight, but the trope came back to bite her in "[[Recap/DoctorWhoS2E3TheRescue The Rescue]]", when she mistook Vicki's pet for a monster and shot it right in front of the girl.
* OddFriendship: With Susan, and additionally becomes the first human companion to befriend the TARDIS.
* OfficialCouple: With Ian, eventually.
* OptOut: With Ian, using the Daleks' time machine.
* SecurityCling: Constantly hugging Susan, bordering on ParentalSubstitute.
* SweaterGirl: Wore an iconic sweater from the TARDIS wardrobe in season 1.
* TeamMom: Especially to Susan.
* WomenAreWiser: She has a habit of walking into a plot, seeing all possible options, and immediately steering everyone towards a solution. On most occasions, it ''works.''

->'''Played by:''' William Russell (196365)

-->''"I know that free movement in time and space is a scientific dream I don't expect to find solved in a junkyard."''

A science teacher at Susan's school who, together with Barbara, gets abducted by the Doctor. Had a fondness for rescuing people, often through good old-fashioned fisticuffs. While decidedly less direct in his approach than Barbara, he adapted quickly to being a TARDIS traveller and put his ChronicHeroSyndrome to good use.

* AbortedArc: He was supposed to be in "Mawdryn Undead", but was replaced by the Brigadier (of all people).
* AccidentalMisnaming: The Doctor called him Chatterton, Chesterfield, Charleston... There's also a less-frequent RunningGag in which aliens or non-anglophone humans have trouble pronouncing the name "Ian".
* TheAgeless: In "Death of the Doctor" on ''Series/TheSarahJaneAdventures'', Sarah Jane, after doing research to find other old companions of the Doctor, says that Ian and Barbara, now married and professors at Cambridge, are said not to have aged since the 1960s.
** However, in a reconstruction of the [[LostEpisode Missing Episodes]] of "The Crusade", William Russell appears as an older Ian to introduce the story.
** Further, "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]" has a FreezeFrameBonus, naming an "I. Chesterton" as the Chairman of the Governors of Coal Hill School, [[{{Bookends}} where he worked]] before traveling with the Doctor.
* AwesomeAnachronisticApparel: After spending months in ancient China as Marco Polo's guest, he keeps wearing his Chinese clothing for the next adventure just for the heck of it.
* BadassInANiceSuit: Exploring a new planet? Battling the forces of evil? Whatever the danger, Ian will face it head-on, and usually faces it in a suit and tie.
* BadassNormal: This garden variety human's achievements include beating the crap out of some soldiers and outsmarting Daleks left and right.
* BadassTeacher: Uses his knowledge of chemistry and physics in a few adventures.
* BewareTheNiceOnes: He's pleasant, charming and easy-going.... and he will ''end'' you if you harm or threaten his friends.
* TheBusCameBack: Both he and Barbara make a surprise appearance the 50th anniversary comic book, "Hunters of the Burning Stone".
* ChronicHeroSyndrome: Even if he can barely walk ([[Recap/DoctorWhoS1E2TheDaleks after being shot by a Dalek]]) or is just recovering from [[Recap/DoctorWhoS1E7TheSensorites severe poisoning]], Ian soldiers on to aid his friends. Or complete strangers.
* DeadpanSnarker: He has a very dry, sardonic sense of humour. Being a schoolteacher, his snark was distinctively SternTeacher humour.
* GoodIsNotSoft: Ian probably kills more people than any other Who companion. (Excluding the Bad Wolf.)
* TheHero: In the early times, he fit this perfectly. Say there's something dangerous that needs to be done, he'll volunteer so the elder and the women stay safe. Say there's someone that needs help, he'll insist on helping them.
* [[HotScientist Hot Science]] [[HotTeacher Teacher]]
* TheLancer: The original intention of the show was to make him TheHero with the Doctor being ''his'' foil. This was back when The Doctor was a jerk and a sourpuss
* NervesOfSteel: He's very quick to leap into action.
* NiceGuy: He's pleasant and easy-going, in contrast to Barbara's somewhat sterner demeanour.
* OfficialCouple: With Barbara, eventually.
* OldSchoolChivalry: He takes it as a matter of course that it should be his duty to protect the old man and the women in his company, and brave the dangers they encounter alone if possible. Susan thinks it's lovely that he takes such good care of them, but Barbara expresses annoyance at his chauvinism on more than one occasion.
* OptOut: With Barbara, using the Daleks' time machine.
* TeamDad: Takes this role to Barbara's TeamMom, with Susan as the child and the Doctor as the curmudgeonly (and later [[TookALevelInKindness kindly]]) grandfather figure.

->'''Played by:''' Maureen O'Brien (1965)

-->''"Oh, something else I forgot to tell you. I think I've poisoned Nero."''

Survivor of a spaceship crash on the planet Dido in the 25th century, Vicki was a teenage girl who then traveled with the Doctor. Had a fondness for monsters and villains and quickly revealed herself to be a NightmareFetishist. As an orphan, she grew extremely close to the Doctor (who had recently lost Susan) and the two developed a makeshift family dynamic.

* {{Adorkable}}: A strong contender for the most adorable companion ever. Her sheer joy at adventuring through history is endearing.
* TheCutie: Absolutely adorable.
* DangerouslyShortSkirt: Her LittleBlackDress lands firmly in this territory.
* FluffyTamer: Aside from the unfortunate HandsOffMyFluffy moment mentioned below, she also christens one of the Zarbi "Zombo", going so far as to call it cute. It being a man-sized ant, the Doctor does not agree.
* GirlishPigtails: Her frequent hairstyle of choice.
* HandsOffMyFluffy: In her first episode, Barbara mistakes Vicki's pet for a monster and shoots it. Vicki properly breaks down.
* HeartwarmingOrphan: A sweetheart with a dead mum and a murdered dad who gains a ParentalSubstitute in the Doctor, shortly after he has left Susan.
* IChooseToStay: She decided to stay in ancient Troy and married [[Theatre/TroilusAndCressida Troilus]], becoming Cressida (yep, the one from Myth/GreekMythology).
* KidSidekick: To the Doctor, as Ian and Barbara are [[OfficialCouple usually paired together]].
* TheKnightsWhoSaySquee: One of the rare companions with literal {{Squee}} moments, notably when she realizes that she's about to meet Nero.
* LittleBlackDress: Her IconicOutfit, a simple black minidress with a prominent zig-zag collar.
* NightmareFetishist: She's first introduced with a feral monster as her pet. The episode after that has her gleefully watching WhileRomeBurns, delighted at how she gets to watch history unfold.
* NoNameGiven: Her last name is never revealed on screen. The ExpandedUniverse has established her full name is Vicki Pallister.
* PluckyGirl:
** She was orphaned by a space accident, and we meet her after she's been stranded on an isolated desert planet awaiting a rescue mission while being psychologically terrorised by a repugnant monster with unclear motivations who turns out to be a man she thought was her friend in disguise - she'd still been making the best of it, by befriending the local wildlife. After the Doctor takes her on she will have occasional scenes where she will remind the others of what she's lost and that the Doctor is now her only family, but is mostly resolute and cheerful, happy to take the lead in a crisis (like in "The Space Museum"), and with a big scoop of NightmareFetishist and FluffyTamer to boot.
** In "[[Recap/DoctorWhoS2E8TheChase The Chase]]" she ''stows away aboard a Dalek time machine'' and when confronted by armed Saxon villagers, tells them to hurry up and make up their minds whether she and Steven are spies or not.
** Sometimes approaches HeroicComedicSociopath dimensions, especially in "[[{{Recap/DoctorWhoS2E4TheRomans}} The Romans]]". (See defining character quote above.)
* ProperTightsWithASkirt: When wearing her introductory short black dress.
* SuspiciouslySimilarSubstitute: For Susan.
** She and the Doctor both discuss how they're looking for lost family in each other. Personality-wise, she's not too dissimilar to Susan, but she doesn't have her more alien outlook on the world.
* TeenGenius: She can talk to the Doctor at close to his own level about time travel theory.
* WhyDidItHaveToBeSnakes: She's "not good with heights". Naturally she has to be winched down a 500-metre drop to escape from the Mechanoids.

->'''Debut:''' "[[Recap/DoctorWhoS2E8TheChase The Chase]]" (1965)
->'''Departure Story:''' "[[Recap/DoctorWhoS3E9TheSavages The Savages]]" (1966)

->'''Played by:''' Peter Purves (196566)

-->''"This is quite a ship you've got here, Doc."''

A very snarky marooned pilot from Earth's future, who stows away on the TARDIS. Deeply traumatised by having spent the few years before that as a prisoner, but adapts quickly to life as a TARDIS traveller.

* AcePilot: One of the few companions ever seen to pilot the TARDIS, albeit under the Doctor's careful supervision.
* ArbitrarySkepticism: He doesn't believe in time travel during his first adventure, even though he has no problem with the whole "bigger on the inside" thing. The Doctor takes ''great'' delight in mocking him.
* CharacterizationMarchesOn: He was introduced in his first full story "[[Recap/DoctorWhoS2E9TheTimeMeddler The Time Meddler]]" as a LoveableRogue and extremely hot-tempered character who (being a space pilot) was already familiar with the way most things worked, condescendingly calling the Doctor 'Doc' and knowing lots about aliens and time travel science. In "[[Recap/DoctorWhoS3E1Galaxy4 Galaxy 4]]" he suddenly develops a much less hot-headed way of voicing disagreements, due to the serial being written for Barbara, and his lines just being hers with some tweaks. In "[[Recap/DoctorWhoS3E3TheMythMakers The Myth Makers]]", he takes a middle route between these two characterisations - the more sombre and respectful air of "Galaxy 4" while getting his confrontational personality from "The Time Meddler" back, which remains his default personality from then on.
* CompanionCube: His stuffed panda, Hi-Fi. The only thing that kept him sane-ish while stuck on the planet Mechanus for two years.
* ADayInTheLimelight: "[[Recap/DoctorWhoS3E5TheMassacre The Massacre]]" is told from his perspective, which arguably makes it the first Doctor-lite episode.
* DeadpanSnarker
* DependingOnTheWriter: He started with a fairly consistent personality but devolved into a cypher due to necessity - at the time, the production was very shaky (new producers, a new technical team, tensions throughout the crew, and a lead actor who was struggling with mental health problems and couldn't remember his lines) and so the writers had to adapt scripts intended for recently departed characters for Steven, and adapt them to de-emphasise the role of the Doctor as there had been talk of completely removing his character and ReTooling the show around Steven. As a result his character ended up filling whatever niche it needed to - funny, serious, an ActionHero, an AllLovingHero, a romantic lead, a quirky Doctor {{Expy}}, and so on. The TARDIS Eruditorum has pointed out that it's possible Steven's chameleonic personality is underappreciated in terms of keeping the show together - it kept stories ticking along well enough that regenerating the Doctor - and thus ensuring the show would continue for decades - became possible.
* TheHeart
* IChooseToStay: He eventually leaves the TARDIS to mediate between two opposing factions of humans (or HumanAliens).
* KnightInSourArmor: Becomes one over the course of his adventures, especially after the many deaths he witnesses in ''[[Recap/DoctorWhoS3E4TheDaleksMasterPlan The Daleks' Master Plan]]'', and the harrowing events of the Massacre of St. Bartholemew's Eve.
* TheLancer: To the Doctor.
* SarcasticDevotee: For all his snarking, he comes to trust the Doctor implicitly. It takes a lot to make Steven waver in his conviction that whatever the Doctor does or asks his companions to do, there's bound to be a good reason.
* WhatTheHellHero: He berates the Doctor and storms out of the TARDIS after they flee the Massacre of St. Bartholomew and leave a young Protestant girl behind.

[[folder: Katarina]]
!!Katarina (First Doctor)
->'''Debut:''' "[[Recap/DoctorWhoS3E3TheMythMakers The Myth Makers]]" (1965)
->'''Departure Story:''' "[[Recap/DoctorWhoS3E4TheDaleksMasterPlan The Daleks' Master Plan]]" (1965)

->'''Played by:''' Adrienne Hill (1965)

->''"She wanted to save our lives, and perhaps the lives of all other beings of the solar system. I hope she found perfection."''
-->-- '''First Doctor'''

A priestess from ancient Troy who thought the Doctor was a god. Her character was considered too limiting and she only appeared in two stories.

* CargoCult: To Team TARDIS, who are [[GodGuise mistaken for gods]] by her.
* ExtremeDoormat: By virtue of being little more than a slave in Troy and believing the Doctor to be a god. This is a major reason why she was written out of the show. A companion who genuinely believes the Doctor to be a god and follows him without question is not an ideal vehicle for drama.
* FamousLastWords: (addressing the Doctor) "You show me so many strange mysteries. [[TemptingFate With you I know I'm safe.]]"
* FishOutOfTemporalWater: The reason why the production team had doubts in her staying power as a companion. It certainly worked a couple of years later with both Jamie and Victoria.
** To be fair though, Jamie was from the year 1745, and Victoria from 1866, while Katarina is from the time of the Trojan War (roughly 1200BC). In Katarina's case, the technological and societal gap was just too great... or would seem so until Leela came along.
* HeroicSacrifice: First companion to leave the show by dying.
* OnlyOneName: May not even have a second name.
* ShooOutTheNewGuy: And she died in only her second adventure and fifth episode (in part 4 of a 12 part epic no less).
** This is even more extreme in real life: Katarina's death scene was actually the very first thing Adrienne Hill filmed in the series.
* ThrownOutTheAirlock: Her demise.

!!Sara Kingdom (First Doctor)
->'''Debut:''' "[[Recap/DoctorWhoS3E4TheDaleksMasterPlan The Daleks' Master Plan]]" (1965-66)

->'''Played by:''' Jean Marsh (1965-66)

-->''"Yes, he's dead. The others must be killed as well. They will be shot on sight but aim for the head."''

Outside of the ExpandedUniverse, she appeared in [[Recap/DoctorWhoS3E4TheDaleksMasterPlan only one, twelve episode long, story, for seven of its episodes]]. She was intentionally written to serve in a companion role (taking over from Katarina) but was never intended to be a permanent character. Sara broke the normal companion mould (then and now) and worked as an agent for a sinister solar system-wide governmental security agency run by the human BigBad. Once she realized her error, she joined the crew of the TARDIS.

* AscendedExtra: There was some debate among fans as to whether Sara Kingdom counted as a Companion, given that [[MauveShirt she's only alive for the course of one adventure]]. However the Dalek Master Plan goes on so long, with her adventures covering different times and planets, that it makes little difference.
* TheAtoner: After she kills her own brother and realizes she has worked for the BigBad all along, leads to her transitioning into a more normal ActionGirl. The novelisation of the story makes this a big part of her character. She is haunted by nightmares of her brother's final moments and continually beats herself up over the fact that she blindly believed Mavic Chen when he said that Bret was a traitor. While she does genuinely want to stop the Daleks and Mavic Chen from destroying the universe, a major secondary reason is that she doesn't want the death of Bret to be in vain.
* DarkActionGirl: At least, the story wants to give his impression when she first appears.
* ExpandedUniverse: When her one and only (very long) story was novelised, it was split into parts. The second began by saying six months had passed since the first. Various Franchise/DoctorWhoExpandedUniverse works have been set in this gap. (The novelizations, incidentally, do not occur in the same continuity as other branches of the EU, or with each other.)
** Several Creator/BigFinish audio dramas featuring her are set after her death, a copy of her personality having lingered on in a wish-granting house in Ely.
* HeroesFightBarehanded: She loses her gun shortly after her introduction, but fights just as well without it in subsequent episodes.
* HeroicSacrifice: Makes one.
* MoreDeadlyThanTheMale: When she and Steven are fighting off two guards, she takes care of the one attacking her before stepping in to finish off the one attacking Steven, all without breaking a sweat.
--> '''Sara:''' Not bad. Remind me to teach you a few tricks sometime.
--> '''Steven:''' Remind ''me'' not to pick a fight with you.
* MyCountryRightOrWrong: Why she's sent to terminate her own brother.
* NervesOfSteel: Even in a crisis, she carries on with her duty, such as when she continues to calmly relay information when the trio's escape ship is being pulled back by the Daleks.
* PerpetualFrowner: As befits her strait-laced, efficient demeanour.
* PuttingOnTheReich: She belongs to the ''SSS'', too.
* RedemptionEqualsDeath: Fits the character arc of someone who does something bad at the start of the adventure serial, only to redeem themselves with a HeroicSacrifice at the end.
* YouLookFamiliar: Jean Marsh had already played a different character, and returned in 1989 to play a third. Oh, and she married Creator/JonPertwee.

->'''Played by:''' Jackie Lane (1966)

->''"If it isn't allowed, Dodo would be first in the queue!"''
-->-- '''Steven Taylor'''

An teenaged schoolgirl from the year 1966. Although a FishOutOfWater in most of time and space, she tried her best to stay brave and ended up saving the day a few times over.

* BreakTheCutie: The ExpandedUniverse thrives on this trope ''anyway'', but Dodo comes in for more than her share. She comes away from her travels with a venereal disease and a nervous breakdown. [[FromBadToWorse And that's just the start of it...]]
* CloudCuckoolander: In her brief time on the show, she manages to stand out as one of the strangest Companions the show has ever had - certainly not stupid, because [[TheCloudCuckooLanderWasRight she frequently makes quick connections about things the Doctor and Steven have missed]], but the ways she expresses her ideas are invariably bizarre. She's also an extremely eccentric dresser (upon discovering the TARDIS wardrobe she immediately [[AwesomeAnachronisticApparel dresses up as a knight]]), and doesn't seem to find the fact that the TARDIS is a BiggerOnTheInside time machine which can never take her back to where she came from remotely weird or upsetting at all.
* ContrastingSequelMainCharacter: To Susan and Vicki - the former was a dark-haired, cautious, weird, ethereal girl and the latter was a blond-haired, outgoing, perky NightmareFetishist. While they were both ImpossibleGenius girls from utopian future civilisations. Dodo was a not-too-bright 1960s woman who implicitly came from a broken home.
* ConvenientlyAnOrphan: And conveniently unhappily adopted by her great-aunt, making this teenager singularly unconcerned by the prospect of never being able to return home.
* TheDitz: It's been joked that she's called Dodo because her brain cells went extinct.
* DoNotCallMePaul: She's not fond of her given name, and insists on being called "Dodo". It takes the Doctor a while to get the message.
* TheGoodOldBritishComp: Dodo was in school uniform when she first entered the TARDIS.
* KilledOffForReal: In the novel ''Who Killed Kennedy''.
* TheMillstone: One of the least intelligent companions the Doctor's ever been saddled with. In "[[Recap/DoctorWhoS3E6TheArk The Ark]]" she nearly wipes out the remnants of humanity by giving them her cold (which they have no immunity to). In "[[Recap/DoctorWhoS3E7TheCelestialToymaker The Celestial Toymaker]]" Steven reminds her of what her plan is three or four times and she still forgets it at the crunch time. In "[[Recap/DoctorWhoS3E8TheGunfighters The Gunfighters]]" she nearly shoots Doc Holliday before the gunfight at the OK Corral.
* NaiveNewcomer: Way out of her depth in her earliest adventures.
* OnlyKnownByTheirNickname: Everyone calls her Dodo.
* PluckyGirl: Very.
* ThePollyanna: Almost always peppy and upbeat.
* PutOnABus: Didn't even get a leaving scene. She waltzed off in "[[Recap/DoctorWhoS3E10TheWarMachines The War Machines]]" and left a note saying she was staying on her native Earth.
* SaveTheVillain: Especially apparent in "The Celestial Toymaker", where her concern and compassion for the other players almost sabotages her and Steven's efforts to recover the [=TARDIS=].
* SuspiciouslySimilarSubstitute: To Vicki, and to a certain extent, Susan. She's the last of three companions to fit the "Doctor's granddaughter" mold.
* TotallyRadical: A 1960s variant of this trope.
* WhatHappenedToTheMouse: What became of her is not mentioned in ''Death of the Doctor''.
* WhatTheHellIsThatAccent: Her dialect veers from Cockney to Manchester.

'''Second Doctor:''' I'd like to see a butterfly fit into a chrysalis case after it spreads its wings.\\
'''Polly:''' Then you ''did'' change.

A sailor from 1966. He and Polly helped the Doctor through his first regeneration. They joined and left the TARDIS crew at the same time as each other.

* ArbitrarySkepticism: Like Steven before him, while he quickly accepts the [=TARDIS=]' interior and its ability to move from place to place, he refuses to believe that it can travel in time. For a while, anyway.
* BerserkButton: Cracks about his height.
* TheCameo: He briefly appears in "Twice Upon A Time" helping the First Doctor through his regeneration.
* TheDulcineaEffect: Ben comes to Polly's assistance when another man at the nightclub won't leave her alone.
* InHarmsWay: When he first appears, Ben's moping every night in the nightclub because he's been given a shore posting.
* IChooseToStay: Both he and Polly decided to go back to their own time in "The Faceless Ones".
* TheNapoleon: He's on the small side, being slightly shorter than Polly, and is also a terrible firebrand.
* OfficialCouple: It's (much) later revealed he and Polly got married, moved to India, and opened up an orphanage.
* PrettyBoy: One of the hottest ''male'' companions in the series.
* TheSkeptic: He has a harder time adjusting to the Doctor's regeneration than Polly.
* TotallyRadical: Intended by the production team to show the new face of ''Doctor Who'' in the swinging mid-sixties.
* WorkingClassHero: Ben is notable for being the Doctor's first explicitly working class companion i.e. he didn't speak in BBC English like everyone else (Dodo started off with a different accent but quickly started speaking in RP anyway). This causes a contrast with Polly, who is more middle class.

'''Polly:''' Then you ''did'' change.

A secretary from 1966. She and Ben helped the Doctor through his first regeneration. They joined and left the TARDIS crew at the same time as each other.

* BoundAndGagged: In "The Smugglers", in Episodes 2/3.
* TheCameo: She briefly appears in "Twice Upon A Time" helping the First Doctor through his regeneration.
* HairOfGoldHeartOfGold: In her first appearance we see her attempting to cheer up Ben, a complete stranger, and later easily parting with some money for a homeless man.
* IChooseToStay: Both she and Ben decided to go back to their own time in "The Faceless Ones".
* NoNameGiven: Polly's surname is never mentioned on screen. It's [[WordOfGod probably]] "Wright". (In "The Faceless Ones", an alien duplicate of her gave her name as "Michelle Leuppi", but given that she was using a different forename there's no reason to suppose she kept Polly's original surname).
* OfficialCouple: It's (much) later revealed she and Ben got married, moved to India, and opened up an orphanage.
* {{Omniglot}}: In "The Underwater Menace", Ben has Polly try to speak to a local whose language they aren't sure of, with the expectation she can do it. Indeed, she goes through four different languages before the person speaks English.
* OnlyOneName: Polly's last name was never revealed on screen, but the scripts indicated it to be Wright, which has been adopted by the Franchise/DoctorWhoExpandedUniverse. A few reference books in the 1980s gave her last name as Lopez, a mishearing of "Leuppi" as mentioned above.
* StayInTheKitchen: Polly gets told to "Go make some coffee" a lot when she asks how she can help. Worse, when they leave the TARDIS crew Ben gets told to find his ship and become an admiral, while Polly should take care of Ben. Though in the ExpandedUniverse short stories from Creator/BigFinish, it's a few years before she and Ben get together, and she forges out her own career in Public Relations, becoming a little like [[Series/AbsolutelyFabulous Edina Monsoon]], and later in ''Series/TheSarahJaneAdventures'', Sarah Jane says that they now run an orphanage in India. Polly was introduced as a scientist's personal secretary, which in 1966 meant that making coffee was more or less her real-life job. It's also arguably justified in a few cases, such as when she's on a late 21st century moon base where all the regular personnel are explicitly described as being highly-qualified scientists. Making coffee and assisting in the sickbay is actually the most helpful thing she can do.
* TotallyRadical: Intended by the production team to show the new face of ''Doctor Who'' in the swinging mid-sixties.

->'''Played by:''' Frazer Hines (196669, 1983, 1985); Hamish Wilson (1968)

-->''"Me? Foreign? ''You're'' the one that's foreign - I'm ''Scottish''."''

The longest running male companion to date, and the longest running of all if you count by single episodes instead of by serials or years active[[note]]Which would be Sarah Jane and Tegan respectively[[/note]]. A young piper of the Clan [=McLaren=], who came from 18th century Scotland. Became extremely close to the Doctor, both emotionally and due to a chronic case of SecurityCling. Although he left at the end of the Second Doctor's televised run, they show up together, with both of them looking much older, for an adventure with the Sixth. This and similarly inexplicable appearances have resulted in the "Season 6B" theory, put forward by several writers and condoned by the BBC, which states Jamie continued to travel with the Second Doctor for many years before "Spearhead from Space".

* AscendedExtra: His character wasn't intended written to be a companion and the production team filmed a version of Jamie's introduction story in which he stayed behind in Scotland.
* BattleCry: "Creag an Tuire!" ("The Boar's Rock", the motto of the [=McLaren=] Clan).
* BraveScot: And very proud of it.
* TheBusCameBack: In addition to a cameo in "[[Recap/DoctorWho20thASTheFiveDoctors The Five Doctors]]", he reappeared in "[[Recap/DoctorWhoS22E4TheTwoDoctors The Two Doctors]]".
* ButtMonkey
* CharacterizationMarchesOn: A fairly severe example, as he was not originally intended to be a companion and was added on after they'd already filmed a scene of the crew saying goodbye to him, with the next few scripts written initially without his character. As a result, he's playing virtually a completely different and unexpectedly minor character in "[[Recap/DoctorWhoS4E4TheHighlanders The Highlanders]]", and in "[[Recap/DoctorWhoS4E5TheUnderwaterMenace The Underwater Menace]]", while he's a fairly active player in events, his dialogue and actions are mostly pilfered from Ben, Polly and some of the RagtagBunchOfMisfits characters in the episode and rewritten in Scottish dialect, leading to a lot of out of character behaviour (notably, [[GetAHoldOfYourselfMan slapping Polly]]). He gets a little scene penned specifically for him in "[[Recap/DoctorWhoS4E6TheMoonbase The Moonbase]]" that expands upon his backstory, but he's playing a [[DistressedDamsel damsel role]] where he's sweet and vulnerable and gets menaced by the monster. In "[[Recap/DoctorWhoS4E7TheMacraTerror The Macra Terror]]" he again gets a little scene capitalising on his Scottishness (when he dances the Highland Fling for the cheerleaders) but spends most of the script as a substitute Polly. He doesn't settle down into his main personality until "[[Recap/DoctorWhoS4E8TheFacelessOnes The Faceless Ones]]", which gives him a lot of things to do, some solid character development and even a GirlOfTheWeek.
* CuddleBug: Any time he's in the same shot as the Doctor, there's a good 50% chance they're hugging, clinging to each other's arms, patting each other's shoulders, climbing all over each other or using each other as pillows.
* FishOutOfTemporalWater: To an extent; he was a quick learner.
* HeroicSacrifice: One of Jamie's ultimate fates in an ExpandedUniverse tale penned by Creator/GrantMorrison in the pages of ''Magazine/DoctorWhoMagazine''.
* HeterosexualLifePartners: He appears in all but the first of Troughton's serials, and this pairing is remembered as one of the best ever.
* LaserGuidedAmnesia: Had all but his first adventure mind-wiped by the Time Lords.
* LongBusTrip: Appeared as a companion to the Sixth Doctor's Creator/BigFinish adventures 25 years since his last appearance in the series; 41 years since his last appearance as a Companion proper. (Frazer winds up playing a ''fictional'' version of Jamie back in the Land of Fiction ... but that's fine, he's got all the same memories of Jamie.) This must be some kind of record.
* ManInAKilt: He's Scottish, what'd you expect?
* MrFanservice: Named "Best Legs In The UK" much to the disappointment of many a young starlet hoping for the title.
* NoSenseOfPersonalSpace: Mostly with the Doctor, but sometimes with the female companions as well.
* TheNthDoctor: "The Mind Robber" replaced Frazer Hines, for an episode or two, for Hamish Wilson, who looked nothing like him. The story explained this by having him run afoul of a trap in the Land of Fiction that required the Doctor to try to reconstruct his face from a bunch of options (facial features hung on a blackboard), kind of like a Mr. Potato Head. He got it wrong the first time, and fixed it the second time, which brought back Frazer Hines. The actor switch was necessary because Frazer Hines had contracted chicken pox during the filming, and so was both contagious and also visibly affected by the disease and so unfit for filming the installments.
* ThePiratesWhoDontDoAnything: He's a piper, yet he's never seen playing the bagpipes. Though, this may be for the best.
* RunningJoke: Jamie would disguise his ignorance of modern technology with a mock-casual. "Aye, that."
* SecurityCling: All the time, especially with the Doctor.
* ShipTease: With Polly, Victoria (especially), Zoe and Peri.
* WhatTheHellHero: He gives a big one to the Doctor in "The Evil of the Daleks".

'''Victoria:''' Thank you. Don't you think it's a bit...\\

A well-brought-up young lady from 1866. She was taken in by the Second Doctor after the Daleks blew up her home and exterminated her father, but she didn't take well at all to a lifestyle of constant danger. Gradually got broken.

* BadassAdorable: She's sweet and small and nervous and she will totally shoot you or attack you with a rogue speeding cart.
* BreakTheCutie: In her first couple of stories she's plucky, adventurous, and a dead shot with a pistol. By her last, she's been reduced to a nervous wreck who can't sleep for fear of the MonsterOfTheWeek. [[http://drwhointerviews.wordpress.com/2009/09/30/deborah-watling-1988/ According to Deborah Watling]], this gradual shift in character was deliberate.

* FishOutOfTemporalWater: Almost everywhere.
* IChooseToStay: She leaves Team TARDIS because she just doesn't want adventures anymore.
* IdenticalGrandson: She "looks just like" her late mother, and there's a portrait to prove it.
* LettingHerHairDown: She's a proper Victorian woman at the beginning with all the baggage that entails. She loosens up quickly around the other two. She doesn't even seem to have any religious hang-ups, unusually for her time and background - in "[[Recap/DoctorWhoS5E5TheWebOfFear The Web of Fear]]", she even wears a mini-skirt.

* VagueAge: In her first serial, she's wearing the full-length dress of an adult, but her hair is still down (an adult would have it pinned up).
* YouCantGoHomeAgain: Because both of her parents are dead and presumably doesn't have any other relatives, Victoria decides not to go back in her own time period.

* ActionGirl: She managed to defeat the Karkus, a superhero, in unarmed combat in "[[Recap/DoctorWhoS6E2TheMindRobber The Mind Robber]]".
* {{Adorkable}}: Smart and adorable.
* BadassAdorable: As seen in "[[Recap/DoctorWhoS6E2TheMindRobber The Mind Robber]]", she's very capable of taking care of herself, when facing off and winning a fight against her favorite fictional character, the Karkus. And the smile on her face when she got Karkus to submit? Priceless.
* BrainyBrunette: Possibly the smartest human companion the Doctor's ever had.
* ContrastingSequelMainCharacter: Whereas Victoria was upper-class, sheltered and fragile, Zoe was smart, confident and studious.
* EmotionlessGirl: In her first serial.
** Though she did seem a little hurt when Leo called her 'all brain and no heart'.

* InnocentFanserviceGirl: Her ''Barbarella''-influenced dress sense goes rather oddly with her bubbly and innocent personality.
* LaserGuidedAmnesia: Same as with Jamie, thanks to those Time Lords. Temporarily removed for the odd Creator/BigFinish adventure; usually returns.
* LittleStowaway: How she joins Team TARDIS.
* LongBusTrip: Much like Jamie above, Zoe is returning to the franchise for a Creator/BigFinish story ''27'' years after her last appearance in the franchise and about ''41'' years after the actual character left the TARDIS. Like Jamie, this has to be some sort of a record. (Unlike Jamie, though, this was the ''real'' Zoe. But [[LaserGuidedAmnesia she doesn't remain.]])
* MsFanservice: Her [[EverythingsBetterWithSparkles sparkly]] [[SpyCatsuit skintight catsuit]] is particularly memorable, especially that [[https://youtu.be/_7QiQUFQ53U?t=2m28s lingering shot of her behind]] in "[[Recap/DoctorWhoS6E2TheMindRobber The Mind Robber]]". And that's not even mentioning the miniskirts and short shorts. It was TheSixties, after all.

* PintSizedPowerhouse: She really is tiny, and as seen in BadassAdorable, capable of taking care of herself.
* RealWomenDontWearDresses: In "[[Recap/DoctorWhoS6E1TheDominators The Dominators]]" (and the novelisation of "The Mind Robber"), she thinks dresses are impractical and doesn't wear them by choice. In "The Invasion", Isobel introduces her to miniskirts, which she seems to like better.

* StrawVulcan: A bit.
* TeenGenius: Although it's never specified just how old she's supposed to be.
* VagueAge: Depending what source you consult, she's anything from 12 to 21, though WordOfGod tends towards 15 or 16. The only onscreen mention of her age is in "[[Recap/DoctorWhoS6E3TheInvasion The Invasion]]", where the Brigadier estimates it as 19. Her actress was 21.
* WaifFu: Adept at it.
* YankTheDogsChain: In just about any ExpandedUniverse work where her LaserGuidedAmnesia is undone, she's amnesiac again (and stands a good chance of being worse off in other respects) by the end.

The Third Doctor's first assistant when he was exiled to Earth. Scientific advisor to UNIT, before the Doctor showed up and casually took her job. Rarely in the mood for the Doctor's shenanigans. Because for her one season, the Doctor was Earthbound, she has the curious distinction of being the only regular companion who never once set foot inside the TARDIS (at least, not on screen).

* AdaptationalSexuality[=/=]BiTheWay: In ''P.R.O.B.E.'' (a ''Doctor Who'' spin-off series of fan videos from the nineties, written by Creator/MarkGatiss), Liz is either a lesbian or bisexual, as she eventually enters into a relationship with Patricia Haggard (played by Louise Jameson).

* PutOnABus: Left for Cambridge offscreen in "Terror of the Autons", apparently dissatisified with her job of "passing the Doctor test tubes". Barry Letts apparently didn't like the character and didn't renew Caroline John's contract, and in any case she would have been unavailable for the next season due to pregnancy. She's said to have returned to UNIT and was stuck in the moonbase as of the ''Series/TheSarahJaneAdventures'' story "Death of the Doctor".
* ShipTease: Perhaps because Liz was the first companion to be the Doctor's intellectual equal, the two had quite a lot of tension between them. He flirts with her on their first meeting in "Spearhead From Space", "The Silurians" opens with a sequence of him explaining to her that even though his car looks old it still has a lot of charm (while lying on the floor looking up her miniskirt) and he strokes her hair while she's looking after him in "The Ambassadors of Death." Liz was the first in a long line of companions to have this sort of relationship with the Doctor. (Well, unless you count [[HoYay/DoctorWho the Second Doctor and Jamie.]])
* WeHardlyKnewYe: Appeared in one series consisting of four stories, plus a cameo in "The Five Doctors".

[[folder: Josephine "Jo" Grant]]
!!Jo Grant (Third and Eleventh Doctors)
->'''Debut:''' "[[Recap/DoctorWhoS8E1TerrorOfTheAutons Terror of the Autons]]" (1971)
->'''Departure Story:''' "[[Recap/DoctorWhoS10E5TheGreenDeath The Green Death]]" (1973)

->'''Played by:''' Creator/KatyManning (19711973)
->Also appeared with the Eleventh Doctor in an episode of ''The Sarah Jane Adventures'' (2010).

->'''Third Doctor:''' I thought you said you took science at [[UsefulNotes/BritishEducationSystem A-Level]].\\
'''Jo:''' I didn't say I passed.

Assistant to the Third Doctor during his exile on Earth. Joined UNIT when a high-placed uncle got her the job, and was quickly shoved onto the Doctor by the Brigadier. However, Jo is far from useless, and will not stand to have someone belittle her. She's an expert in escapology and can easily get out of a jam, or fight back when she needs to, so don't let her cute looks fool you. Jo is a passionate and gentle soul who deeply cares about people, and will do what she can to help them, even if it means risking her life. She sometimes will get a little too focused on them and [[TheDitz forget about her own safety]], and she can be [[MotorMouth really excitable]]. Returned briefly as a companion to the Eleventh Doctor in ''Series/TheSarahJaneAdventures''.
* BadassAdorable: Look at those faces she pulls -- look at the way she knocks out prison guards with food trays. When she beats up several large soldiers and runs off with one of their motorcycles, everyone is surprised.
* BewareTheNiceOnes: Incredibly charming, equally disarming.
* BoundAndGagged: In ''[[Recap/DoctorWhoS9E1DayOfTheDaleks Day of the Daleks]]'', in Episode 2, when she's captured and tied up in the basement of Auderly House by time-travelling resistance fighters.
* BunnyEarsLawyer: Quirky, cute, and at times something of a clutz, but overall good at her job as the Doctor's laboratory assistant. Though the Doctor initially rejected Jo as scientifically incompetent, the Brigadier was correct in his assertion that what the Doctor needed was "someone to pass you your test tubes and tell you how brilliant you are".
* TheBusCameBack: She became a companion to Eleven for one episode, along with Sarah Jane.
* CombatStilettos: Combat Platforms, really; she spends most of her serials tackling mountains, quarries, and open fields in three-to-four-inch platform boots.
* ContrastingSequelMainCharacter: Whereas Liz was an intelligent, astute and ambitious scientist, Jo was young, ditzy, somewhat uneducated scientifically and scream-prone. This was done because it was felt [[Creator/TerranceDicks by some]] that Liz was too like [[OmnidisciplinaryScientist the]] [[DeadpanSnarker Doctor]] and the assistant's job was [[DamselInDistress get captured and scream a lot]]. The fact that [[Creator/RobertHolmes others]] immediately established her as also brave, resourceful [[EscapeArtist and specifically good at escaping capture]], along with Katy Manning's winning portrayal and warm relationship with Pertwee, nicely averted a potential ReplacementScrappy situation.
* CoolOldLady: In ''Series/TheSarahJaneAdventures'', where she returns to the series after an absence of just under 40 years, but has lost nothing of her charm and sweet nature.
* CrouchingMoronHiddenBadass: In ''[[Recap/DoctorWhoS8E2TheMindOfEvil The Mind of Evil]]'' most prominently, where she and the doctor, aided by the rehabilitated prisoner Barnham, carried the Keller Machine to the site of the Thunderbolt missile to incapacitate the Master, preventing him from launching the missile at the World Peace Conference.
* CuteClumsyGirl: Jo's first meeting with the Doctor didn't bode well. She mistook an important experiment for an accidental fire and ruined it by dousing it with a fire extinguisher.
--> "I've really got off to a terrific start haven't I? I find the man everybody's looking for, I forget where he is, and I end up by trying to blow you all sky-high."
* DependingOnTheWriter: Whether in trope terms she's a genuine [[TheDitz Ditz]], a CrouchingMoronHiddenBadass, or engaging in full-blown ObfuscatingStupidity.
* TheDitz: Not to a ''huge'' extent, as oftentimes exaggerated by fandom. Jo does have her ditzy moments, but otherwise her intelligence is quite normal.
* EscapeArtist: She's a trained escapologist, and can often wriggle her way out of trouble. Thus, while she was hardly immune to being captured, this rarely did the bad guy any good.
* FauxActionGirl: Was originally meant to be an [[Series/TheAvengers Emma Peel]]-{{expy}} -- traces of this can be seen in her karate-chopping Sgt Benton in "Terror of the Autons", brandishing a gun in "The Mind of Evil" and her talents as an EscapeArtist. Eventually though it became easier for the writers to portray Jo as TheDitz and DamselInDistress. In fairness Jo was a rookie -- she'd been ''trained'' as a secret agent, but had no experience.
* GrandmaWhatMassiveHotnessYouHave: Even Rani points it out (!) in ''Series/TheSarahJaneAdventures'' when it's clear that she's lost nothing of her sparkle.
* GranolaGirl: The Doctor notes that she's exceptionally bad at trying to be a scientist, and tries to get it into her head that it is not, in fact, the dawning of the age of Aquarius.
* HairOfGoldHeartOfGold: Easily one of the warmest companions in the series, with a heart as golden as her hair.
* HappilyMarried: She stayed with Dr. Jones, having him met him during the events of ''[[Recap/DoctorWhoS10E5TheGreenDeath The Green Death]]'', and had seven kids with him. They went on to have thirteen grandchildren, and we meet one of them, Santiago, during her appearance in ''Series/TheSarahJaneAdventures''.
* TheHeart: Whilst Jo was certainly a member of the team, her individualism made her stand out in UNIT and her desire to follow her own instincts and speak her mind made the Doctor and her close -- so much so that she was a contributing factor in softening him up considerably during her tenure on the series.
* HoldingHands: The Doctor and Jo always held hands while running... because actress Creator/KatyManning was so short-sighted that during the filming of their first adventure together, she ran straight into a tree.
* ManicPixieDreamGirl: A platonic version (although Creator/KatyManning insists otherwise). Her friendship with the Third Doctor makes him a [[TookALevelInKindness more open and softer]] person, and he's noticeably hurt when she leaves him.
* MsFanservice: Arguably one of the Doctor's hottest companions -- her wardrobe of mini-skirts, majorette boots and occasional panty-shots help out....''a lot''. That and the time Manning posed naked with a Dalek.....
* NiceGirl: A very sweet, appealing young woman.
* ObfuscatingStupidity: She's quite ditzy, but knows how much she can get done by acting just a bit ditzier.
* PluckyGirl: Not many people can politely tell the Master that they aren't going to let themselves be hypnotised again, as seen in ''[[Recap/DoctorWhoS10E3FrontierInSpace Frontier In Space]].''
* ThePowerOfLove: Gigantic invincible intergalactic demon about to wipe out mankind? No problem.
* ShipTease: Subtle, but towards the end of her tenure, Three seemed to be more emotionally open towards Jo. Many speculated that had Cliff not existed, and the BBC higher-ups would've allowed it, Jo and Three would've gotten together.
* SoapBoxSadie: And it actually works out for her -- she left UNIT, and therefore the Doctor, to marry Professor Clifford Jones, who at the time had received United Nations funding for a variety of progressive scientific studies.
* UndyingLoyalty: To the Doctor. Even if it means certain death, she won't leave his side.
* WalkingTheEarth: It's what she's been doing since she got married. She travels everywhere and stages protests with her huge family. She does so much of this that the TARDIS, which can go anywhere and any when, could not track her down.
** The trait seems to be passed down to her children and grandchildren as well. Her grandson, Santiago, introduced in "Death of the Doctor," was born in Chile (hence his name) because that was where his parents happened to be at the time.
* TheWatson: Much of her job consists of asking the Doctor what's happening.
* WideEyedIdealist: Eventually finds a lifestyle that allows her to make a change for the planet.
* WillTheyOrWontThey: She enjoys a mild flirtation with Mike Yates and in ''[[Recap/DoctorWhoS9E2TheCurseOfPeladon The Curse of Peladon]]'', she's all ready to go out on a date with him, until the Doctor whisks her away.
* [[YouLookFamiliar You Sound Familiar]]: Katy Manning also plays transtemporal adventuress Franchise/IrisWildthyme, who has her own spinoff in the Franchise/DoctorWhoExpandedUniverse. (Though technically they don't actually sound all that similar, with Manning voicing Iris in a husky, "[[OopNorth centuries of gin and fags, chuck!]]" voice.)

!!Surgeon-Lieutenant Harry Sullivan (Fourth Doctor)
->'''Debut:''' "[[Recap/DoctorWhoS12E1Robot Robot]]" (1974-75)
->'''Departure Story:''' "[[Recap/DoctorWhoS13E1TerrorOfTheZygons Terror of the Zygons]]" (1975)

->'''Played by:''' Ian Marter (197475)

-->''"Steady, steady on, old girl, steady on."''

A surgeon lieutenant at UNIT, of the old-fashioned gentleman variety. Originally posted to UNIT from the Royal Navy as a medical orderly, he joined Team TARDIS after the Brigadier told him to keep an eye on the Doctor, which Harry took to mean "across time and space". Had a habit of getting stuck down gentle slopes and being attacked by entirely stationary animals.

* BadassNormal: No matter what Four says, Harry had his badass moments.
* TheBusCameBack: After his departure as regular character in "Terror of the Zygons", he made one more appearance later in the season, in "The Android Invasion" (the last 1970s UNIT story to feature any recurring characters from the organisation).
* TheCharacterDiedWithHim: In ''The Sarah Jane Adventures'' episode "Death of the Doctor", he's referred to in the past tense, implying that Harry is dead.
* TheChewToy: The Fourth Doctor picked on him ''a lot''.
* DistressedDude: All the time. Infamously got nearly eaten by a Skaro clam, despite clams not exactly being known for their high velocity or their predatory abilities.
* GenreRefugee: According to Creator/TerranceDicks, he was supposed to be a ridiculous, over-the-top ''Boy's Own'' adventure hero who had somehow found himself in a ''Doctor Who'' story, being narratively upstaged by the Doctor and not quite able to realise why this is happening to him. He doesn't really scan as this after "[[Recap/DoctorWhoS12E1Robot Robot]]", due to [[DependingOnTheWriter other writers taking his genre quirks more seriously]].
* InformedAbility: He's a doctor (a literal one of medicine), but always seems out of his element. The Doctor teases him about it and jokes that Harry's only qualified to operate on sailors. Creator/BigFinish states that he ends up working as a virus researcher for NATO. Later, in ''Series/TheSarahJaneAdventures'', Sarah Jane confirms that after his time with the Doctor, he did pioneering work with vaccines, saving thousands of people.
* JustFollowingOrders: His reason for joining the TARDIS crew.
* TheMedic: He's medically trained.
* MildlyMilitary: He's a Royal Navy Surgeon-Lieutenant, but he rarely ever acts like it.
* TheNicknamer: Continually referred to Sarah Jane as "Old Thing" and had similar nicknames for other characters.
* OldSchoolChivalry
* QuintessentialBritishGentleman: "I say!"
* RememberTheNewGuy: He's first introduced as an established member of UNIT, who's apparently already very familiar with the Doctor. In fact, the Brigadier makes a phone call to the medical officer "Lieutenant Sullivan" in the story before his actual debut.
* StrawMisogynist: Can be pretty sexist and condescending towards Sarah Jane. This was deliberate by the production team in order to contrast with Sarah Jane's StrawFeminist traits.
* UnfazedEveryman: He takes everything in his stride.
* YouLookFamiliar: Ian Marter had a minor part in the Third Doctor serial "[[Recap/DoctorWhoS10E2CarnivalOfMonsters Carnival of Monsters]]" before being cast as Harry.

->'''Debut:''' "[[Recap/DoctorWhoS18E3FullCircle Full Circle]]" (1980)
->'''Departure Story:''' "[[Recap/DoctorWhoS19E6Earthshock Earthshock]]" (1982)

->'''Played by:''' Creator/MatthewWaterhouse (198082)

-->''"Could anyone pass the sodium chloride, please?"''

A snotty teenage maths geek from E-Space, annoying in the way that snotty teenage geek-boys usually are, but a well-meaning kid all the same. The Doctor saw him as an incompetent underling, despite the fact that Adric was an absolute genius when it came to maths -- just one who had a lot of learning to do about personal skills. As a result, Adric felt ignored, unwanted and rejected, and tried coming up with his own creative solutions to solving each episode's problems. Usually very unsuccessfully. It all came to a head when he had a falling out with the Fifth Doctor and demanded to be returned to his home in E-Space.

Unfortunately, the TARDIS crew ran afoul of a Cybermen plot to lay waste to future humankind, and just barely managed to throw their plans off course. After a very brutal battle against the Cybermen, Adric's fate was tragically sealed when he became trapped inside a crashing freighter on an unstoppable collision course with prehistoric Earth. After the TARDIS navigation controls were blown up by enemy fire, the Doctor and company could only watch the inevitable unfold. With no hope of rescue, Adric braced himself for the end, sharing his late brother's fate of an equally young and bitter demise. His loss devastated the Fifth Doctor, haunting him all the way to the very last moments of his life, and it deeply affected his fellow companions Tegan and Nyssa with pain and regret.

* AllOfTheOtherReindeer: Adric is everybody's ButtMonkey from the word go, and seen as an annoying tagalong more than anything else. At the start of "Earthshock," he actually confronts the Doctor about the way he's being treated by everybody, and how he's completely sick of it. The Doctor dashes out of the TARDIS as fast as he can just to avoid having to talk about those things.
* AntiHero: A bit of a jerk towards people at times. Notably, he felt that women aren't good for anything, which didn't exactly make him popular with fellow companions [[{{Tsundere}} Tegan]] and [[TeenGenius Nyssa]].
* TheArtfulDodger: It's even part of his character concept.
* BerserkButton: Adric ''puts a girl in a stranglehold'' for trying to take his maths badge. ''In his first scene.'' It is a lot more heartbreaking in hindsight considering his ultimate fate, and how [[EmpathyDollShot his badge ends up symbolically broken.]]
* {{BFG}}: Used for a ''very'' weakly executed but surprisingly effective one-man BigDamnHeroes moment near the end of "Warriors' Gate."
* BigEater: A large amount of his character motivation throughout the episodes stems from just wanting to find some food.
* BizarreAlienBiology: His HealingFactor.
* ContrastingSequelMainCharacter: Whereas Romana was so competent that she often took charge and had the Doctor learning from her, Adric was a young boy genius who the Doctor was raising as a protege.
* DyingAlone: On a crashing spaceship, thinking he just failed to save the world.
* {{Expy}}: He was conceived as [[Literature/OliverTwist The Artful Dodger]] in space.
* FakeDefector: Considering he does this ''twice'' over the course of his time in the TARDIS ("[[Recap/DoctorWhoS18E4StateOfDecay State of Decay]]", and "[[Recap/DoctorWhos19E3Kinda Kinda]]"), it's not surprising that a lot of fans accuse him of "always siding with the villain." (He also has a habit of ''actually'' siding with the villain. Or being kidnapped by the villain and being forced to use his abilities for said villain. Or just stealing the villain's mecha and accidentally shooting at innocent bystanders...)
* FamousLastWords: "Now I'll never know if I was right..."
* GoodWithNumbers: His main thing.
* GuileHero: Becomes a plot point a few times.
* HealingFactor: You'd think it'd be a massively useful trait for a companion to have, given the scrapes they get into, but Adric's HealingFactor is only mentioned twice -- in "[[Recap/DoctorWhoS18E3FullCircle Full Circle]]" (his introductory story) and again in "[[Recap/DoctorWhoS19E4TheVisitation The Visitation]]."
* HorribleJudgeOfCharacter: Towards [[AffablyEvil Monarch]] in "[[Recap/DoctorWhoS19E2FourToDoomsday Four to Doomsday]]." [[UtopiaJustifiesTheMeans Turning the entire population of Earth into androids to rid them of disease]] sound like a ''good'' idea to you?
* HumanAliens: Adric's species had three evolutionary forms, only one of which is humanoid.
* IconicItem: His mathematical excellence badge. Seeing it shattered on the floor of the TARDIS at the end of "Earthshock" makes the SilentCredits all the more powerful.
* InformedAbility: For a supposed genius, Adric doesn't come off as being particularly intelligent. It's likely that, to use the classic TabletopGame/DungeonsAndDragons metaphor, he's high intelligence, low wisdom (and [[JerkWithAHeartOfGold charisma]]).
* InsufferableGenius: He very much wanted to be one of these, but his sheer incompetence at pretty much anything outside of mathematics pretty much scuttled the character. As such, he frequently came across as being more "Insufferable" than "Genius".
* JerkWithAHeartOfGold: To an extent. The "jerk" part doesn't really emerge until season 19, but ultimately he still cares.
** Justified in the long run. He starts off in season 18 in the shadow of the Fourth Doctor, who acts very smug, alien and impervious, making it hard to speak his mind, but Romana and K9 are also there to keep him in check, so he doesn't have to voice complaints. However, when Romana and K9 leave, Adric starts to voice his disdain, which is only furthered when traumatised Nyssa and especially argumentative Tegan join him as companions and the squabbling reaches a new high. Then the Doctor regenerates into his fifth incarnation, who is a lot more humbled, humane and vulnerable, removing the air of fear to speak out in front of him. Adric, of course, cuts loose on him.
* LimitedWardrobe: Wears the same yellow rompers in every single story.
* LittleStowaway: How he got on the TARDIS in the first place.
* TheMillstone: In "[[Recap/DoctorWhoS19E1Castrovalva Castrovalva]]", he allies himself with The Master after being captured by him, and in "[[Recap/DoctorWhoS19E5Earthschock Earthshock]]", the whole plot is kicked off by him arguing with the Doctor over wanting to return to his home planet [[spoiler:which eventually results in his death]].
* MrViceGuy: Driven by a desire for approval and acceptance. Whenever there's an older man in the plot, who's in charge, has a power complex and probably some kind of plan to take over the world, Adric will cling to the guy like a perfect little teacher's pet.
* NewPowersAsThePlotDemands: Ability-wise, Adric is a surprisingly well-equipped companion, demonstrating proficiency in lock-picking, sleight-of-hand, and knife-throwing, amongst [[GoodWithNumbers other]] [[HealingFactor things]]. The catch? Most of them only get used in one story, two if it's really lucky.
* RummageSaleReject: He wore ill-fitting pajamas with a rather childish star on the pocket and bright green boots.
* SenselessSacrifice: Without achieving anything.
* TeenGenius: And proud of it.
* ThisLoserIsYou: Conceived as somebody who the geek element of the fanbase would empathise with, but was too accurate a portrayal of a snotty, socially-inept teenage geek to appear in any way flattering.
* TookALevelInJerkass: In Season 19.
* WhatHaveWeEar: He teaches the Doctor a few coin tricks.
* WideEyedIdealist: The Doctor neatly summarizes it:
--> '''Fifth Doctor:''' Now listen to me, you young ''idiot''. You're not so much gullible as idealistic. I suppose it comes from your deprived delinquent background.
* YouCantGoHomeAgain: Because it's in a different universe. He's working on finding a solution when he dies.

->'''Played by:''' Creator/SarahSutton (198183)

-->''"Do you have any books on telebiogenesis?"''

A teenaged biologist and the daughter of Tremas, who got his body possessed by the Master at the end of Fourth Doctor serial "[[Recap/DoctorWhoS18E6TheKeeperOfTraken The Keeper of Traken]]." Quiet, stoic and very handy with electronics. One of the most accomplished TARDIS pilots among the companions; she was even able to fly it solo (with assists from Tegan in "[[Recap/DoctorWhoS19E1Castrovalva Castrovalva]]" and Adric in "[[Recap/DoctorWhoS19E4TheVisitation The Visitation]]").

* EightiesHair: A big mess of brown curls.
* AngstWhatAngst: The implications of her tragic backstory are barely mentioned in the show, but the ExpandedUniverse would make use of all her emotional baggage. [[invoked]]
** TheStoic: It's implied, on the show and in the expanded universe, to be why her pain rarely shows.
* AscendedExtra: Was never intended to be a companion, until producer Creator/JohnNathanTurner decided otherwise.
** Even as a regular, Nyssa tended to have less to do than everyone else: unlike Adric, Tegan, or Turlough, she was rarely ever the focus of a story, with the sole exception being her final appearance in "Terminus." The character ''really'' ascended in the Big Finish audios, though: the fact that both Janet Fielding and Matthew Waterhouse initially declined to reprise their roles as Tegan and Adric (and Nicola Bryant's Peri appearances tended to be split with Colin Baker's Sixth Doctor) meant that Nyssa was one of the most frequent companions for Peter Davison's fifth Doctor in the early years of the range.
* BewareTheNiceOnes: "[[Recap/DoctorWhoS20E1ArcOfInfinity Arc of Infinity]]." She ''pulls a gun'' on the ''Time Lord President'', amongst many others. Sarah Sutton notes in the DVD commentary how unusually trigger-happy Nyssa was in this story.
* BrainyBrunette: Very clever. She was able to fly and repair the TARDIS, and could talk about space and time on the Doctor's own level, although she lacked his experience.
* BreakTheCutie: She's had her planet destroyed and her father possess by the Master. She copes very well.
* CannotTellALie: While an expert on many subjects, Nyssa was not much use when it came to subterfuge.
* GiantPoofySleeves: Wore them at times, but was eventually forced to discard the dress for something practical.
* GirlyGirl: To Tegan's tomboy.
* TheHeart: One of the nicest, most compassionate companions ever to grace the TARDIS.
* HotScientist: Her first season had her covered from head to toe, after which (as Creator/PeterDavison put it) she suddenly magically lost half of her clothes.
* HumanAliens: Looks completely human, like Adric.
* IChooseToStay: She leaves the TARDIS crew to stay on [[Recap/DoctorWhoS20E4Terminus Terminus]] and try to restructure it into a proper hospital.
* IdenticalStranger: Ann Talbot, a {{blue blood}} from the roaring 20's.
* InnocentAliens: From a planet where evil is outright banned.
* InnocentFanserviceGirl: Famous for the skirt removal bit in "[[Recap/DoctorWhoS20E4Terminus Terminus]]," which the actor herself has described as "[[{{Fanservice}} a gift to the fans]]".
* [[LastOfHisKind Last Of Her Kind]]: The rest of Traken died in "[[Recap/DoctorWhoS18E7Logopolis Logopolis]]" -- though in the ExpandedUniverse book "Cold Fusion" there's mention of a Trakenite colony that survived.
* LimitedWardrobe: Her burgundy velvet ensemble throughout Season 19.
* LiteralMinded: A running gag in the serials and audios is Nyssa's imperviousness to jokes.
* NiceGirl: Really sweet.
* OddFriendship: With Tegan, who is almost her polar opposite, and with Adric, who becomes like a little brother to her.
* OnlySaneWoman: Out of Five's companions, Nyssa is the most rational, sensible and level-headed.
* PluckyGirl: Eager to see the world.
* PrettyInMink: One of her outfits had a fur-trimmed jacket.
* ProperLady
* TheQuietOne: In comparison to Adric and Tegan.
* TheReliableOne: Stoic, quiet and capable.
* TeenGenius: Able to understand the TARDIS.
* TomboyWithAGirlyStreak: Wore make-up, feminine styled hair, and skirts, in addition to being a practical intellectual and adventurer.
* VaporWear: Especially noticeable in "Terminus."
* WrittenInAbsence: An unfortunate side-effect of being added to the cast at a relatively late stage, many of the scripts following Nyssa's introduction had relatively little for her to do. The most notable example of this was the serial "Kinda," where she inexplicably faints and naps off-screen in the TARDIS for the remainder of the serial.
* YouCantGoHomeAgain: Traken is destroyed by the universal entropy caused by the Master's meddling in "[[Recap/DoctorWhoS18E7Logopolis Logopolis]]."

->'''Fifth Doctor:''' How do you feel now?\\
'''Tegan:''' Groggy, sore, and bad-tempered.\\
'''Fifth Doctor:''' Almost your old self, then!

A brash UsefulNotes/{{Australia}}n, inadvertently kidnapped from 1981 just as she was about to start a new job as a flight attendant. Created to help sell the show to Australia. Once described herself as "just a mouth on legs". One of a very few companions seen to pilot the TARDIS, albeit not very well. Longest-serving companion if you count by consecutive years active.

* EightiesHair: The short, Sheena Easton variety. "A Fix With Sontarans" later shows her with the eightiest hair imaginable.
* ADayInTheLimelight: "Kinda" and "Snakedance" focus on her.
* AndIMustScream: Her second time hosting the Mara.
* BookDumb: Subverted. Tegan was as well-educated as one would expect of a late-20th Century human. But she was flying around in the TARDIS with the Doctor, Adric, Nyssa and Turlough -- all of whom were aliens from very advanced species.
* BreakTheHaughty: Her second time hosting the Mara in her head doesn't leave her asleep through the ordeal, and she experiences it as a horrific AndIMustScream situation. She ends up with a disturbingly realistic trauma, crying and shaking while all the Doctor can do is hold her. The violence and death (of "a lot of good people" in Tegan's words) that is integral to the Doctor's travels eventually became too much for her, hence her departure. Later expanded universe stories that follow up on her post-Doctor life suggest that she suffered from a form of PTSD.
* TheCatCameBack: The Doctor eventually got her back to where she wanted to be (Heathrow, about to start her new job), but several months too late. She returns in the next season, having lost her job before she even arrived and managed to find the TARDIS again.
* ContrastingSequelMainCharacter: Whereas Romana was alien, patient and erudite, Tegan was down-to-earth, bossy and abrasive.
* DeadpanSnarker: There's a reason she's called "the mouth on legs".
-->'''Tegan''': Is that supposed to be Heathrow?
-->'''Adric''': It is.
-->'''Tegan''': Well, they've certainly let the grass grow since I was last there.
-->'''Adric''': Well, actually, they haven't built the airport yet. We're about three hundred years early.
-->'''Tegan''': That's great! Perhaps I can go out, file a claim on the land. When they get round to inventing the aircraft, I'll make a fortune.
* DemonicPossession: Guess who becomes the Mara's host ''both'' times it shows up?
* DepartmentOfRedundancyDepartment: "How do we find the index file? Of course, if we had an index file, we could look it up in the index file under 'index file'! What am I saying?!"
* IgnoredEnamoredUnderling: Much of her characterisation is hard to interpret in any way other than her having an unrequited love for the Fifth Doctor that couldn't be explicitly stated because of the NoHuggingNoKissing. Apart from the fans who think that the unrequited love was for Nyssa instead.
* LimitedWardrobe: For some reason, keeps wearing her mauve cabin crew uniform throughout Season Nineteen.
* LineOfSightName: How the character was named. Creator/JohnNathanTurner was either going to choose Tegan, for an Australian friend's niece, or Jovanka, after the wife of Yugoslavian president UsefulNotes/JosipBrozTito. Script-editor Christopher H. Bidmead read Tegan as the first name and Jovanka as the last name. The rest, as they say, is history.
* NoSell: She manages to shut an immortal, eternal being out of her mind in "Enlightenment", just because he was annoying her ''too'' much.
* OddFriendship: With Nyssa, who's quiet, scientifically-minded, and always willing to help out --the exact opposite of Tegan.
* OptOut
--> It just isn't fun, anymore.
* PluckyGirl: Very.
* SarcasticDevotee: Tegan is probably the best-known example of this trope in the original series. She's usually either snarking at The Doctor, snarking at Adric, or snarking at the Monster of the Week (even, when, as in the Creator/BigFinish drama "Heroes of Sontar," it nearly gets both her and the Doctor killed...)

* {{Tsundere}}: The ''deredere'' being nearly vestigial.
* UnfazedEveryman: Her first reaction on seeing the inside of the TARDIS isn't shock, or even curiosity -- but the immediate urge to go seek out the pilot and tell him he's a rubbish driver.

->'''Departure Story:''' "[[Recap/DoctorWhoS21E5PlanetOfFire Planet of Fire]]" (1984)

->'''Played by:''' Mark Strickson (198384)

-->''"What is it about Earth people that makes them think a futile gesture is a noble one?"''

An alien noble exiled to Earth after a revolution on his planet, Turlough is posing as an English schoolboy when the Doctor meets him. Gets drafted by the Black Guardian with a promise of freedom if he kills the Doctor, but Turlough just isn't evil enough to go through with it. While the Doctor and Turlough have had their differences, Turlough eventually grew to consider the Doctor his closest friend. Just don't expect him to admit it.

* AntiHero: Starts out as the TokenEvilTeammate, but it's quickly revealed he's not actually evil -- just troubled.
* AwesomeMcCoolname: Has a very alien name.
* ChewingTheScenery: A specialty of his.
* ChivalrousPervert: He even gets some in various ExpandedUniverse tales. Lord knows it'd never happen on camera.
* ContrastingSequelMainCharacter: Whereas Adric was arrogant and boastful, Turlough was secretive and withdrawn. Whereas Adric would pretend to defect to villains, Turlough actually was working with a villain. At first, anyway.
* DeadpanSnarker: Particularly towards Tegan, who's [[{{Tsundere}} just as capable]] of snarking right back.
* DealWithTheDevil: How he starts out.
* DistressedDude: Done often because the writers couldn't figure out what to do with Turlough.
* {{Fanservice}}: He sure took a lot of clothes off in "[[Recap/DoctorWhoS21E5PlanetOfFire Planet of Fire]]"... not that the tight short-shorts were concealing much to begin with.
* HeelFaceTurn: He starts out plotting to kill the Doctor for the Black Guardian, but eventually becomes the Doctor's loyal friend.
* HumanAliens: Looks human, and can apparently pass as one in superficial medical examination.
* LastNameBasis: No one ever calls him "Vislor".
* LimitedWardrobe: Except for "Planet of Fire," he stays in his school uniform for his entire run. Fortunately, it's sufficiently low-key as a school uniform that the audience soon forgets what it's meant to be and he becomes a SharpDressedMan.
* LongLostSibling: His brother.
* MarkOfShame: On his arm.
* MinionWithAnFInEvil: To the Black Guardian.
* TheMole: Initially.
* MysteriousPast: And we learn what it is in his ''final episode''.
* ShirtlessScene: Combined with SexySoakedShirt -- with speedos.
* TeenGenius: Although he may be older than the British schoolboy he was posing as. Understood the TARDIS well enough to set it to go to the Doctor on autopilot with a time-delayed takeoff.
* TheSoCalledCoward: Is actually quite happy to jump into action.
* ThickerThanWater: Cares tremendously for his brother.
* TokenEvilTeammate: When the Doctor first meets him. And even after he becomes a trusted companion and friend of the Doctor, he's just as liable to abandon or betray the Doctor as he is to rescue him and his companions. Turlough's morality remains slightly dubious, even up to his last episode, but he always seems to redeem himself in the end.

->'''Voiced by:''' Gerald Flood (198384)

-->''"Unexpected as it may be, I do have a mind of my own."''

A shape-changing robot that the Master acquired as a sort of souvenir from the planet [[Recap/DoctorWhoS19E7TimeFlight Xeriphas]], this character quite literally vanished into the TARDIS rather than becoming a Companion. (The robot was a prop from some other project that was never made, was shoe-horned into ''Doctor Who'', and was promptly written out again when it proved to be an absolute nightmare to use, with its pre-programmed lines constantly going out of sync and suffering repeated breakdowns, and its creator died without leaving sufficient instructions behind as to how to control it.) Showed up in "[[Recap/DoctorWhoS20E6TheKingsDemons The King's Demons]]" as a ''villain'' and puppet of the Master, got cut from an appearance in "[[Recap/DoctorWhoS21E2TheAwakening The Awakening]]" and [[DroppedABridgeOnHim made a final appearance]] in "[[Recap/DoctorWhoS21E5PlanetOfFire Planet of Fire]]."

* DroppedABridgeOnHim: He dies. The end.
* ExpandedUniverse: Actually fleshed-out in several novels, and makes one key appearance in the AudioPlay/BigFinishDoctorWho episode "[[Recap/BigFinishDoctorWho091CircularTime Circular Time]]". The reason he doesn't appear more is because [[http://en.wikipedia.org/wiki/Kamelion#The_Curse_of_Kamelion.3F several people perished]] (the creator/programmer of Kamelion, actors who portrayed him, a DW author who wrote a novel specifically [[ADayInTheLimelight centred around the character]]) when they had some major involvement with the character, and others now fear his existence is an [[{{Curse}} accursed affair.]]
** ''The Crystal Bucephalus'' by Craig Hinton, decides that Kamelion's [[WeakWilled unfortunate weakness]] would often work against both the heroes (in that Kamelion would be aiding the villain of the week, in this case a mobster/corrupt religious leader) and the villains (by specifically trying to undermine the villain in key ways that wouldn't be disobeying him). Said novel also took Kamelion and turned him from a robot into a complex sentient mathematical equation that ''likes'' taking the form of a robot instead. At least, this helps explain why the Master was so interested in him, as well as the way Kamelion changes form.
* ForgottenFallenFriend: Never mentioned again on the TV show, whatsoever; though he does appear in an easily visible photograph, among those of many other former companions, in [[Recap/DoctorWho50thASTheDayOfTheDoctor "The Day of the Doctor"]]. Creator/PaulCornell did bring back Kamelion for the Big Finish ''Circular Time'' audio drama, in a short episode that delves into the Fifth Doctor's rather unusual Regeneration scene.
* MercyKill: The less said about this one, the better.
* PunnyName: Get it?
* RobotBuddy: Literally.
* ShapeShifting: His main power.
* ShooOutTheNewGuy: Technically he was a companion for nearly a full year. In practice, he only showed up in 2 stories, the one where he joined and the one where the writers DroppedABridgeOnHim.
* SuspiciouslySimilarSubstitute: Was conceived as a successor to K-9, just not looking like a dog.
* IWantMyJetpack: Non-fictional example. Kamelion was envisioned as a highly advanced robotic prop, but the technology (and budget) around at the time of his conception was just too limited to allow for a versatile robot, which doomed his character to obscurity when he proved a veritable nightmare to operate.
* WeakWilled: [[HeelFaceRevolvingDoor Very easily manipulated]] by the willpower of others.
* WeHardlyKnewYe: Only appears twice.

[[folder: Perpugilliam "Peri" Brown]]
!!Perpugilliam "Peri" Brown (Fifth and Sixth Doctors)
->'''Debut:''' "[[Recap/DoctorWhoS21E5PlanetOfFire Planet of Fire]]" (1984)
->'''Departure Story:''' "[[Recap/DoctorWhoS23E2Mindwarp The Trial of a Time Lord: Mindwarp]]" (1986)

->'''Played by:''' Nicola Bryant (198486)

->'''The Master:''' I am the Master!\\
'''Peri:''' So what? I'm Perpugilliam Brown, and I can shout just as loud as you can!

The series' only regular American companion ([[FakeAmerican supposedly]]), Peri was a botany student who stumbled into the TARDIS while she was on holiday. Got a bit of a shock during her third televised adventure, when her kind gentlemanly Doctor suddenly regenerated into a peremptory {{jerkass}} and tried to murder her in the middle of his regeneration trauma. Developed a lot of attention from fans due to her tendency to wear [[FormFittingWardrobe tight clothes]].

* EightiesHair: With a headband and everything.
* AbhorrentAdmirer: Peri has an unfortunate knack for attracting lustful weirdos, such as Sharaz Jek and the Borad.
* AbsoluteCleavage: Just ask Creator/PeterDavison. Some of her wardrobe is actually modest.
* AbusiveParents: She has a nightmare about her step-father in her first appearance: fans were left to draw their own (generally unpleasant) conclusions. In the ExpandedUniverse, she was molested as a child. BreakTheCutie indeed.
* BareYourMidriff: She regularly tied up her shirts to reveal her midriff.
* BoundAndGagged: In "Mindwarp", in Episode 4.
* BreakTheCutie: The ExpandedUniverse seems to delight in doing this to poor Peri. One tale winds up killing off her entire family. And not just that, but it was an utter afterthought in a story's epilogue where Peri had ''already'' lost some people who were like family to her. Another example deals with the alternate possibilities coming from her final appearances. The ExpandedUniverse gave her quite a few different fates in varying (mutually incompatible) stories. The Creator/BigFinish episode "[[Recap/BigFinishDoctorWhoCCS5E7PeriAndThePisconParadox Peri and the Piscon Paradox]]" dives headfirst into this idea, and follows a Peri who's in her late 40s, living on Earth, and completely oblivious to the existence of a Sixth Doctor. It turns out that the Celestial Intervention Agency decided to toy with her after [[Recap/DoctorWhoS23E2Mindwarp the Trial]] and made ''copies'' of her, just to find one fate for her that would give her a decent ending. ''This'' Peri wound up marrying her high school sweetheart... and was abused repeatedly by her "perfect husband", to the point where she's rendered incapable of having children. She slowly gets used to the idea of having a messed-up life, only to have it interrupted by a run-in with her old self as well as the Fifth ''and'' Sixth Doctors. MoodWhiplash at its best.
* {{Chickification}}:
** In her first story, "Planet of Fire", she is one of the very few characters who ever [[NoSell No Sold]] the Master's hypnotic powers with no previous experience of them or mental training. And she gives a snarky line in response. Unfortunately, it looks as if the writers looked at her characterisation in "The Caves of Androzani", in which she is painfully dying for most of the story, and thought that was the way she should be all the time, as the serial itself proved to be highly acclaimed, owing much of its success to her distress.
** Arguably more a case of NeverLiveItDown; after that episode, she proceeds to hold two renegade Time Lords at gunpoint, get the Doctor out of various traps and gets a cool moment in "Attack of the Cybermen" where she and the Doctor move in unison to take out some armed guards.
** Likewise, the Sixth Doctor also went through an arguable characterisation faux pas via violent mood swings and the show had trouble finding its footing. Season 23 managed to recover their intended characterisations, but both characters were soon given the axe in a most unfair manner due to then-BBC Controller Michael Grade having said axe to grind with the series, putting it on hiatus. Nicola Bryant's contract ran out while the show was on hiatus and she was given a departure story to wrap things up. Her co-star Colin did not fare so well, who was fired from his role and pushed out the door on such unfair terms he refused to shoot a departure story and didn't get one until 29 years later, in audio format.
* ConstantlyCurious: She gets confused about how time travel works, when she asked Six how there can be two [=TARDISes=] after meeting his second incarnation and also about why Five wears a stick of celery.
* DeadpanSnarker: Often. It's to be expected when her travelling companion is the Sixth Doctor.
-->'''Sixth Doctor:''' I suddenly feel very conspicuous.
-->'''Peri:''' I'm not surprised in [[ImpossiblyTackyClothes that coat!]]
* DistressedDamsel: All the time.
* TheDitz: Season 22, mostly. Luckily, she improved drastically in her last season, not to mention her [[AudioPlay/BigFinishDoctorWho audio adventures]].
* DomesticAbuse: The infamous scene in "The Twin Dilemma" where a freshly regenerated Sixth Doctor throttles poor Peri is reminiscent of this. She also has a disturbing dream about her stepfather in "Planet of Fire". The Expanded Universe ran with it and both Peri's stepfather and future husband were abusive towards her. The audio adventure "Peri and the Piscon Paradox" explores this:
-->'''An older Peri:''' Cute blonde guys can turn into scary violent guys real quick.[[note]]She's not just talking about the Doctor there.[[/note]]
* EstablishingCharacterMoment: Her very second shot is of her in a bikini, after which she immediately proceeds to almost drown.
* FamousLastWords: (If you don't accept the inquisitor's story) Protect me! I am your lord and master!
* FormFittingWardrobe: Had a thing for skin-tight clothes. Season 23, after a lot of family-friendly ExecutiveMeddling, toned down her wardrobe to conservative dress.
* InformedAttribute: Peri was a student of botany but she rarely, if ever, got to put this to use. Ironically, the very first serial after she left the show ("Terror of the Vervoids") featured a race of plant-like aliens as the villains. Poor Peri just couldn't catch a break.
* MaleGaze: Her second scene. The camera pans up over her body in a bikini. Perhaps the most blatant {{Fanservice}} ''Doctor Who'' has ever had.
* MsFanservice: Her aforementioned tight wardrobe. Which was a bit unfair on poor Ms. Bryant, as both she and Colin have pointed out in more than one commentary that England can be ''[[CaptainObvious really cold]]''.
* OohMeAccentsSlipping:
** Nicola Bryant auditioned for Peri by secretly impersonating an American accent because she wanted to be on the show, when the producers were scouting out someone who had a real American accent. She's actually got a native British accent and it slips through many times because it's her natural dialect.
** Very pronounced in the ''Big Finish'' audio dramas. Oddly, Nicola Bryant doesn't seem to have any problem slipping back into the accent she used on the television show for certain stories, but in others she tends to speak with something much closer to her natural British accent. In general, when she appears alongside Colin Baker's sixth Doctor, she speaks with an American accent, but, strangely enough, her (chronologically earlier) appearances alongside Peter Davison's fifth Doctor feature a British accent. Which means that at some point Peri switched from an American to a British accent, and then back again. Could be FridgeBrilliance, in that Peri's accent generally got more convincing the longer Bryant was on the show, and so in her Five audios Bryant my deliberately affect a less convincing accent.
* ParentService: Another blatant example like Leela before her.
* PluckyGirl: With Five, although with Six she's more of a Perpetually Annoyed Girl.
* ShipTease: With the doctor, which is even more prominent in the ExpandedUniverse. She even admits she fancies Five.
* ShouldntWeBeInSchoolRightNow: Depending on what her fate really is, as Peri is said to be a college student majoring in botany when she met the Doctor while on a holiday. See the alternate possibilities above.
* {{Tsundere}}: With the [[JerkWithAHeartOfGold Sixth Doctor]].
* VitriolicBestBuds: With the Doctor, especially after the messy regeneration experience. Their default state is to complain about each other, but if one of them gets in serious danger, expect a strong reaction from the other.
--> "What do you do in that box?"
--> '''The Doctor:''' (affectionately) "Argue, mainly."
* WackyAmericansHaveWackyNames: ''Perpugilliam?!''

->'''Departure Story:''' "[[Recap/DoctorWhoS24E4Dragonfire Dragonfire]]" (1987)

->'''Played by:''' Bonnie Langford (198687)


A computer programmer from Pease Pottage, Mel was well known both for having a particularly piercing scream and being obsessive about her health (and the Doctor's, for that matter). She had a cheerful disposition and a perfect memory.

* EightiesHair: Giant red curls.
* CharacterizationMarchesOn: Her obsession with the Doctor's health. Possibly justified as he did end up changing physically, just [[TheNthDoctor not in a way]] she expected.
* DistressedDamsel
* DitzyGenius: She's very clever, but ''very'' ditzy.
* FieryRedhead: Without the typical fighting capability.
* GiantPoofySleeves: With polka dots.
* IChooseToStay: With Sabalom Glitz, for some reason. (She was supposed to leave in the previous serial, Ray would have been the Doctor's companion, and Ace would have stayed with Glitz -- [[WordOfGod her lover]]. Things got shuffled around during production and Mel ended up staying with Glitz instead.)
* InformedAbility: Mel supposedly had a PhotographicMemory, but this never came up. Similarly, about the only time her experience as a computer programmer comes up is when she inexplicably identifies the Valeyard's doomsday machine as "a megabyte modem."
* MakeMeWannaShout: Bonnie Langford was hired because she had a scream "that could tear the paint off walls". It's [[http://www.youtube.com/watch?v=8928yni-Cl0 not far from the truth]].
* MultipleChoicePast: Since Mel never got a proper televised introduction (see below), the expanded universe novels and audios have built a cottage industry out of creating one for her, most of which are mutually contradictory.
* NiceGirl: She's very sweet.
* NoIndoorVoice: Infamously so.
* NoNameGiven: Mel's last name is never mentioned on screen. It was established as Bush in studio documents and a book written by the series' producer at the time, and also appears in [[Franchise/DoctorWhoExpandedUniverse the Expanded Universe]].
* ThePiratesWhoDontDoAnything: She's a computer programmer, yet she never touches one during her tenure.
* [[RememberTheNewGuy Remember The New Girl]]: She was introduced as being from the Doctor's future, which means that the manner in which she first encountered and started traveling with the Doctor wasn't shown then. At the end of the season, she's seen departing with the Doctor, whom she has already met, but who hasn't yet met her. The production team apparently intended to explain all of this and give her a proper introduction the following season, but the forced departure of Colin Baker as the Doctor made that impossible. So, ultimately, Mel was just... there, with no real introduction ever shown, at least until the expanded universe got their hands on her.
* ThePollyanna: Very upbeat, cheerful, optimistic and trusting.
* ScreamingWoman: The actress was hired for her scream which could "tear the paint off walls". For "[[Recap/DoctorWhoS23E3TerrorOfTheVervoids Terror of the Vervoids]]", Creator/JohnNathanTurner asked her to do a {{cliffhanger}} scream on an "F" note, just so her scream would segue seamlessly into the ending credits. [[https://www.youtube.com/watch?v=VC6cFsPG7dE She did]].

->'''Played by:''' Creator/SophieAldred (198789)

-->''"I'm ready for them. Question is, are they ready for me?"''

A [[TheEighties late-eighties]] teenager rescued from an ice planet where she was working as a waitress (long story). Notable as one of the relatively few classic series girls who actively attempted to beat up the monsters rather than scream at them. She also liked to deploy her favourite weapon, a homemade explosive she called Nitro-9. Always called the Doctor "Professor", even after he asked her not to. This started out as an example of her anti-authority bent, then turned into an affectionate nickname between them. Oh, and she was the reason the CrowningMomentOfAwesome trope page was created.

* EightiesHair: A tight ponytail or braid near the top of her head.
* AbortedArc: Had the show not been placed on hiatus, the Doctor would have enrolled Ace in ''the Time Lord Academy'' so she could undergo training to become a Time Lord. The planned episode dealing with this plan, "Thin Ice," was eventually recorded by ''Creator/BigFinish'' in audio format, and Ace eventually gets into the Academy in the Big Finish ''AudioPlay/{{Gallifrey}}'' series under Romana's presidency. A version of this also happens in the BBC webcast audio play ''Death Comes To Time''.
* ActionGirl: She defeated a Dalek with a ''[[BatterUp baseball bat]]'', shot another in the face with a [[{{BFG}} rocket launcher]], sniped Cybermen with a slingshot, and had an unhealthy love for homemade explosives.
* AllergicToEvil: In the "Remembrance of the Daleks" novelization, any sign of racism brings flashbacks to the fire in Manisha's apartment.
* AmbiguouslyGay: Very much DependingOnTheWriter. Creator Ian Briggs [[AllThereInTheManual wrote a sexual liaison with Sabalom Glitz into her character outline]], although it was never made explicit in the series. [[WordOfGay Other writers]], like Rona Munro, intentionally wrote her as a ButchLesbian (as much as the BBC would permit anyway). Ace occasionally has chemistry with male guest stars (notably Captain Sorin in "[[Recap/DoctorWhoS26E3TheCurseOfFenric The Curse of Fenric]]"), but it's much more common with the ladies. In the ExpandedUniverse, she ReallyGetsAround, although she's only seen hooking up with men. Her TV series appearances average out to BiTheWay, which Sophie Aldred herself agrees with.
* AntiHero: She's not a very mentally stable person, and she's gotten in trouble with the law before.
* AscendedExtra: The original plan was for Ace and Glitz to leave Ice World at the end of the episode, and Ray (from "Delta and the Bannermen") would have been Seven's companion. When that didn't pan out, Ace became an AscendedExtra and Mel stayed with Glitz instead. This is also the reason Glitz knows where Ace lives -- it was originally meant as ForeShadowing. WordOfGod has it that Glitz and Ace were sleeping together and that he took her virginity.
* BerserkButton: Do ''NOT'' call her 'small'. One Dalek made this mistake, and Ace's reaction...[[https://www.youtube.com/watch?v=dtUMnn0-4zw see for yourself...]]
* BootsOfToughness: Favours rugged Doc Marten boots, where most companions' footwear tends to the flimsy and fashionable.
* BrainsAndBrawn: Seven was a consummate {{Chessmaster}} and MagnificentBastard who rarely dirtied his hands with a fight. Ace whipped up homemade explosives and rarely met a fight she didn't like.
* BrokenBird: The girl had ''issues''. And guidance counsellors.
* CartwrightCurse: Became close to [[Recap/DoctorWhoS25E1RemembranceOfTheDaleks Mike Smith]], [[Recap/DoctorWhoS26E2GhostLight Gwendoline Pritchard]], [[Recap/DoctorWhoS26E3TheCurseOfFenric Captain Sorin]] and [[Recap/DoctorWhoS26E4Survival Karra]]; none of them made it to the end of their respective serials. The ''Literature/DoctorWhoNewAdventures'' continued the trend.
* CatchPhrase: Enjoyed shouting "Ace!" (meaning "cool"). Since this is also her nickname, it almost seems like she is engaging in PokemonSpeak.
** She said "Wicked!" so often that the Doctor himself was inspired to say it once.
** Also "Oi!"
* ContrastingSequelMainCharacter:
** The concept for Ace was basically 'the exact opposite of Mel'. Mel was a girly, garishly-dressed do-gooder who nagged the Doctor into improving his health, wheras Ace was a punky tomboy who lived on a council estate and blew things up with homemade explosives.
** Unlike most of the previous females companions, she acts more like a daughter/granddaughter figure, similar to the likes of Susan and Victoria.
* CrazyPrepared: Even before meeting the Doctor, she was in the habit of taking a portable rope ladder with her wherever she went.
* DarkAndTroubledPast: The epitome of this trope, to the point where the type of Doctor that Ace really needs is a therapist.
* DarkActionGirl: Already shows it in the TV series, and really becomes this trope in the ''Literature/DoctorWhoNewAdventures'' novels.
* {{Delinquent|s}}: Stated to have been one in her backstory: she was excluded from school for blowing up the art room, burned down an abandoned house, and (probably for this) was cautioned by police. She is also able to drive a car despite not being old enough to hold a licence, suggesting illicit joyriding.
* DemolitionsExpert: Okay, so she may have a couple bugs to work out, but when surrounded by enemies?
-->'''Ace''': ''Do you feel like arguing with a can of deodorant that registers nine on the Richter scale?''
* ExpandedUniverse:
** One of the most frequently appearing companions in the Franchise/DoctorWhoExpandedUniverse, especially during her friendship with Characters/BerniceSummerfield in the ''Literature/DoctorWhoNewAdventures'' series. In Creator/BigFinish, ''two'' versions of Ace appear: the regular one, and the one in the Creator/BigFinish stories that take place in the ''New Adventures'' series (still following us?). She's also all over the ''Magazine/DoctorWhoMagazine'' comics. All ExpandedUniverse incarnations of Ace have her gradually becoming ''[[UpToEleven even more badass]]''.
** While there's usually at least a token effort made to reconcile various contradictions in expanded universe fiction, the writers basically seem to have given up trying with Ace, especially when it comes to her departure. She has four or five completely contradictory fates in the novels, comics, and audios, and though there have been some ideas floated to try to reconcile them all (usually involving clones or alternate timeline duplicates), none of them appear to have gained much traction to date.
* GirlOfTheWeek: The censored WordOfGay version. Ace appeared in nine stories, and rapidly established a close friendship with an attractive young female character in at least five of them.
* GoodLookingPrivates: Ace always falls for men in uniform who later turn out to be the enemy.
* GoshDangItToHeck: Much of the TotallyRadical comes from the writers' attempts to have her insult people or express emotion without swearing.
* IHaveManyNames: Is her birth name Dorothy [=McShane=][[note]]As it is in the New Adventures novels[[/note]] or Dorothy Gale[[note]]In the BBC Books novels[[/note]]? Or Dorothy Gale [=McShane=][[note]]In the Big Finish audios[[/note]]? Later on, she abandons the "Ace" nickname in favor of "[=McShane=]".[[note]]Briefly in the Big Finish audio dramas[[/note]] Or possibly "Dorothee".[[note]]In the New Adventure novels[[/note]]
* KillItWithFire: Her preferred method.
-->'''Seventh Doctor:''' I don't believe you've met my young friend Ace, an expert in calorification,[[labelnote:]](setting things on fire)[[/labelnote]] incineration,[[labelnote:§]](setting things on fire)[[/labelnote]] carbonization,[[labelnote:º]](setting things on fire)[[/labelnote]] and inflammation.[[labelnote:]](''yes'', setting things on fire)[[/labelnote]]
* KilledOffForReal: In the infamous ''Magazine/DoctorWhoMagazine'' comics story "Ground Zero". As noted, though, Ace had several conflicting fates in the Franchise/DoctorWhoExpandedUniverse. And this one got ignored by Creator/RussellTDavies, who wanted Aldred in ''Series/TheSarahJaneAdventures'', were it not for the untimely death of Creator/ElisabethSladen.
** Ace is an inverted example of a MultipleChoicePast. Her origins are pretty straightforward, but her future is in considerable doubt. "Ground Zero" itself contradicted the story told in the earlier novelizations and New Adventures novels, which had her adopting the name Dorothee and retiring to late nineteenth century France with a time ring that allowed her to travel approximately 100 years into the past or future. And it was in turn contradicted by the BBC Books novels by Mike Tucker and Robert Perry, which killed her off in an entirely different way. The Big Finish audios haven't provided a conclusion to the character yet, but the direction they've taken the character in is hard to reconcile with any of the preceding three. And, finally, the audio drama "Death Comes to Time" has her becoming the last of the Time Lords, but that story has a difficult relationship with the rest of ''Doctor Who'' canon even leaving that aside.
* TheLadette: Although she only fully achieves this trope in terms of debauched lifestyle after her Literature/DoctorWhoNewAdventures age-up.
* MadBomber: She's very quick to whip out those homemade explosives of hers. The Doctor is more than aware of this.
--> '''Seventh Doctor:''' "ACE! Hand me some of that Nitro-9 you're not carrying."
* MeaningfulName: Her name's Dorothy, and she ends up in the future by a "time storm". If that wasn't enough, [[AllThereInTheManual her middle name is ''Gale''.]] Does this [[Literature/TheWonderfulWizardOfOz remind you of anything]]?
* NervesOfSteel: She does get scared occasionally, but pushes on regardless. When she doesn't ''want'' to push on, the Doctor [[TricksterMentor makes her]].
* TheNicknamer: She's best known for calling the Doctor "Professor", but she invented names for other characters as well. Mel ended up as "Doughnut".
* NoNameGiven: Her surname is not given on screen, but audios use Dorothy Gale [=McShane=].
** The name given by the audios is itself a compromise: her full name had originally been given in the New Adventures novels and ''Doctor Who Magazine'' comic as "Dorothy [=McShane=]." When BBC Books took over the novel license, the writers gave it as "Dorothy Gale." Big Finish was more closely tied to the earlier New Adventures novels restored it to "[=McShane=]," but with the addition of "Gale" as her middle name.
* PintSizedPowerhouse: Just don't call her small.
* PopCulturedBadass: Look closely at her jacket, and you can spot (among other things) a ''Comicbook/{{Watchmen}}'' pin, two ''ComicStrip/RupertBear'' pictures, several ''Series/BluePeter'' decorations, a Gerry Anderson fan club membership button, and a ''Series/{{Thunderbirds}}'' patch.
* PsychoSidekick: Downplayed, in that a vague description of the dynamic between them would make Ace seem like a Psycho Sidekick, but the Seventh Doctor is much more ruthless than she is, in a less personally violent way.
** Especially in "The Curse of Fenric" where the Doctor cruelly calls her an "emotional cripple". It's in order to [[CruelToBeKind save her life]] by forcing her to lose faith in him so the big bad can't destroy the world. But it's still a pretty nasty thing to do to a character established as carrying a lot of emotional baggage.
* ReallyGetsAround: Not on television, but in the Franchise/DoctorWhoExpandedUniverse novels, Ace seems to shag someone in every novel.
* StableTimeLoop: She meets her grandmother, who she helped rescue her mother, therefore causing her own existence.
* StuffBlowingUp: The Doctor's companions are generally there to help minimise collateral damage, but she bucked the trend by bringing her own supply of ''home-made explosives'' (Nitro-9) on her travels. The Doctor tended to discourage this... except when it was useful to him ("Hand me some of that Nitro-9 you're [[BlatantLies not carrying]]").
* SupportingProtagonist: When Andrew Cartmel tried to re-instil some mystery into the Doctor and made him a conniving Chessmaster, Ace ended up getting the most character development of any companion from the classic series.
* {{Tomboy}}: She's not even remotely like previous companions.
* TotallyRadical: Try and listen to some of the dialogue and the slang she uses without cringing. Go on. We dare you. (Ian Briggs, the writer who created her, gave her a speech pattern based on teenagers he knew, but was forced to change the slang because his real teenagers were using words the BBC wouldn't allow its fictional teenagers to say.)
** A bit of an [[AluminumChristmasTrees Aluminum Christmas Tree]] as a large portion of her slang is [[http://www.peevish.co.uk/slang/index.htm genuine]] (if occasionally obscure) British slang.
* WeaponOfChoice: Explosives!
* WholesomeCrossdresser: In "Ghost Light."
* YouCalledMeXItMustBeSerious: If Ace calls the Doctor "Doctor" instead of "Professor", it's a sign she's genuinely upset.

[[folder: Dr. Grace Holloway]]
!!Dr. Grace Holloway (Eighth Doctor) [[note]]She met Seven first, but wasn't a companion until after he regenerated into Eight.[[/note]]
->'''Debut:''' [[Recap/DoctorWhoTVMTheTVMovie Doctor Who: The TV Movie]] (1996)

->'''Played by:''' Creator/DaphneAshbrook (1996)

-->''"Doctor, I only have ''one'' life. Can you try to keep that in mind?"''

Only on-screen companion of the Eighth Doctor, Grace also has the dubious distinction of having ''killed'' the Seventh Doctor. She's a cardiologist from 1999 San Francisco with a fondness for opera.

* AllLoveIsUnrequited: Her boyfriend leaves her. Her new love interest is an amnesiac Time Lord.
-->''"I finally meet the right guy... and he's from another planet!"''
* ArbitrarySkepticism: She comes off a bit like this; one minute, she's floating the possibility that the man with two hearts and blood that is "not blood" is some kind of (presumably hyper-advanced) "weird genetics experiment". The next minute, when he's claiming to be an alien, she's screaming that he's a lunatic and running away from him in terror. Oh really, Grace? Granted, the Doctor's [[YouHaveToBelieveMe not exactly presenting his case as well as he can at that point]] but it's not like her explanation is any more plausible.
* AtTheOperaTonight: She's attending the opera when she's called to operate on the Doctor.
* BigDamnKiss: The first companion to ever be kissed on the lips by the Doctor. She promptly asks him to do it again. The Master gets a kiss in as well, when she's BrainwashedAndCrazy.
** Creator/DaphneAshbrook still shares little kisses with Creator/PaulMcGann at conventions, and has taken to kissing other Doctors as well -- she says she's trying to collect them all. So far, she's managed to lure in Creator/PeterDavison, Creator/ColinBaker and Creator/SylvesterMcCoy.
* BlackEyesOfEvil: When she's possessed by the Master's influence.
* BrainwashedAndCrazy: Due to being hit by the Master's poison/acidic saliva.
* DeadpanSnarker: With a lot of eye-rolling.
* HeroesWantRedheads: And likes snogging them.
* HospitalHottie: Especially in her big dress.
* NiceJobBreakingItHero: Her attempt to save the Seventh Doctor was the ''cause'' of his death (she was thrown by his BizarreAlienBiology), forcing him to regenerate into Eight.
* NoHuggingNoKissing: Forever averted. She and the Doctor happily make out.
* {{Omake}}: Creator/DaphneAshbrook is a strong contender for "[[OneOfUs geekiest companion]]" in the whole series, and enjoys chatting with fans on [[http://daphneashbrook.tumblr.com her tumblr]], frequently in character as Grace.
* PeoplePuppets: To the Master.
* RefusalOfTheCall: Ultimately, she decides not to go with the Doctor, and the Doctor refuses to stay on Earth with her. (Creator/BigFinish confirms that they stay friends, and that he visits her on occasion.)
* WritingAroundTrademarks: Due to extensive copyright issues, Grace is still not allowed to appear in ''Series/DoctorWho'' adaptations. The ''Magazine/DoctorWhoMagazine'' comics somehow found a way around the legal issues and gave her a major guest appearance in one story, but other Franchise/DoctorWhoExpandedUniverse spinoffs can't go any further than mentioning her by name. This hasn't prevented Daphne Ashbrook from appearing in other roles, though, and she's reunited (albeit as a very different character) with Creator/PaulMcGann in Creator/BigFinish.
** However she acts as 8's companion in [[ComicBook/DoctorWhoPrisonersOfTime "Prisoners of Time"]], where he turns up to ask her for a trip, though she finds it overwhelming.
