Doctor Who/Characters/Companions and Supporting Cast/Classic Series Companions

Susan "Foreman" (First Doctor)
"Oh, grandfather!"

"Played by: Carole Ann Ford (1963-64, 1983, 1993)"

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.
 * The Bus Came Back: While Susan has certainly been on a Long Bus Trip, she did return for one adventure in 1983. There is also an audio adventure featuring her and the Eighth Doctor together, but that's of debatable canon.
 * Human Aliens: From the same race as the Doctor. Never seen regenerating, though.
 * It Runs in The Family
 * Long Bus Trip: Returns briefly in the 20th anniversary special The Five Doctors and the Big Finish audio An Earthly Child.
 * Put On a Bus: Done at the end of the serial "The Dalek Invasion of Earth" where the Doctor leaves her behind so she can marry a nice young resistance fighter and have some stability in her life. She would have stayed with her grandfather out of a sense of obligation if he hadn't.
 * Bus Crash: The Doctor stated he was the Last of His Kind as early as "The End of the World". In the later episodes "The Empty Child", "Fear Her" and "The Doctor's Daughter", the Doctor reminisces about having had children once, and confirms that he considers every last Time Lord dead.
 * Screaming Woman: The original screamer. That was why the actress left the show after only one season - she got tired of this role.
 * Shipper On Deck: The Big Finish Companion Chronicle "Here There Be Monsters" opens with her talking about how she thinks that Ian and Barbara truly belong together.
 * Thicker Than Water: She feels strongly about her duty to her grandfather.

Barbara Wright and Ian Chesterton (First Doctor)
"Ian: We'd better keep an eye on [the Doctor]. He seems to have a knack of getting himself into trouble."

"Played by: Jacqueline Hill and William Russell (1963-65)"

Two teachers at Susan's school (history and science, respectively); together with Susan, the first three companions.


 * The Ageless: Sarah Jane, after doing research to find other old companions of the Doctor, comments that Ian & Barbara, now married and professors at Cambridge, are rumored not to have aged since the 1960s.
 * Badass Normal: Barbara ran over Daleks with a lorry. The series' 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."
 * As for Ian, he had his moments of awesome as well, which include beating the crap out of some soldiers and outsmarting Daleks left and right.
 * Badass Teacher: Both of them, with Barbara being the bigger Bad Ass of the two.
 * Brainy Brunette: Barbara.
 * The Lancer: Ian. Oddly, the original intention of the show was to make him the hero with the Doctor being in this role.
 * Hot Librarian: Barbara.
 * Hot Scientist: Ian.
 * Mistaken for Gods: Barbara, in "The Aztecs".
 * Official Couple

Vicki (First Doctor)
"Oh, something else I forgot to tell you. I think I've poisoned Nero."

"Played by: Maureen O'Brien (1965)"

Survivor of a spaceship crash on the planet Dido (so she did go down with the ship...), she was a teenage girl who then traveled with the Doctor. She decided to stay in ancient Troy and married Trolius, becoming Cressida (yep, the one from Greek Mythology).


 * Hands Off My Fluffy
 * I Choose to Stay
 * The Knights Who Say Squee: One of the rare companions with literal Squee moments, notably when she realizes that she's about to meet Nero.
 * No Name Given: Her last name is never revealed on screen. The Expanded Universe has established her full name is Vicki Pallister.
 * Plucky Girl: In "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.
 * Suspiciously Similar Substitute: For Susan.
 * Teen Genius: She can talk to the Doctor at close to his own level about time travel theory.

Steven Taylor (First Doctor)
"This is quite a ship you've got here, Doc."

"Played by: Peter Purves (1965-66)"

A marooned pilot from Earth's future, he eventually leaves the TARDIS to mediate between two opposing factions of humans (or Human Aliens).


 * Companion Cube: His stuffed panda, Hi-Fi. The only thing that kept him sane-ish while stuck on the planet Mechanus for two years.
 * The Lancer
 * What the Hell Hero: 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.
 * You Are in Command Now: How he leaves the show. Two factions choose him as their new ruler during their peace negotiations.
 * You Look Familiar: Purves plays a different character in an earlier episode of the same story in which Steven is introduced.

Katarina (First Doctor)
"First Doctor: She wanted to save our lives, and perhaps the lives of all other beings of the solar system. I hope she found perfection."

"Played by: Adrienne Hill (1965)"

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


 * Heroic Sacrifice: First companion to leave the show by dying.
 * Shoo Out the New Guy: And she died in only her second adventure and fifth episode (in part 4 of a 12 part epic no less).
 * Mistaken for Gods: Inverted.
 * Only One Name
 * Thrown Out the Airlock

Sara Kingdom (First Doctor)
"Played by: Jean Marsh (1965)"

Outside of the Expanded Universe, she appared in 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 mold (then and now) and worked as an agent for a sinister solar system-wide governmental security agency run by the human Big Bad. Once she realized her error, she joined the crew of the TARDIS.


 * The Atoner: After she kills her own brother and realizes she has worked for the Big Bad all along, leads to her transitioning into a more normal Action Girl.
 * Dark Action Girl: at least, the story wants to give his impression when she first appears.
 * Expanded Universe: 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 Doctor Who Expanded Universe 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 Big Finish audio dramas featuring her are set after her death. Somehow.
 * Heroic Sacrifice
 * The Pirates Who Don't Do Anything: Dressed as a badass with a zap gun, but doesn't really do much of anything after her introductory episode.
 * Putting On the Reich: She belongs to the 'SSS, too.
 * You Look Familiar: Jean Marsh had already played a different character, and returned in 1989 to play a third.

Dorothea "Dodo" Chaplet (First Doctor)
"Steven: If it isn't allowed, Dodo would be first in the queue!"

"Played by: Jackie Lane (1966)"

Rather a forgotten companion, she waltzed off in "The War Machines" and left a note saying she was staying on her native Earth.


 * Break the Cutie: The Expanded Universe 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. And that's just the start of it...
 * Oop North: Famously invoked (Manchester accent) and then revoked after BBC fiat.
 * Plucky Girl
 * Put On a Bus: Didn't even get a leaving scene.
 * Totally Radical: A 1960s variant of this trope. There's probably a good reason she was forgotten.

Ben Jackson and Polly (First and Second Doctors)
"Ben: The Doctor always wore this. If you are him it should fit... That settles it!

Second Doctor: I'd like to see a butterfly fit into a chrysalis case after it spreads its wings.

Polly: Then you did change."

"Played by: Michael Craze and Anneke Wills (1966-1967)"

From 1966. The pair - he was a sailor, she was a secretary - helped the Doctor through his first regeneration. They joined and left the TARDIS crew at the same time as each other.


 * The Dulcinea Effect: Ben comes to Polly's assistance when another man at the nightclub won't leave her alone.
 * Good Looking Privates: Ben in his Able Seaman's uniform.
 * In Harms Way: When he first appears, Ben's moping every night in the nightclub because he's been given a shore posting.
 * No Name Given: Polly's surname is never mentioned on screen. It's 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).
 * Only One Name: Polly's last name was never revealed on screen, but the scripts indicated it to be Wright, which has been adopted by the Doctor Who Expanded Universe. A few reference books in the 1980s gave her last name as Lopez, a mishearing of "Leuppi" as mentioned above.
 * Stay in The Kitchen: 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.
 * Totally Radical: Intended by the production team to show the new face of Doctor Who in the swinging mid-sixties.

Jamie McCrimmon (Second Doctor)
"Me? Foreign? You're the one that's foreign - I'm Scottish."

"Played by: Frazer Hines (1966-69, 1983, 1985); Hamish Wilson (1968)"

The longest running male companion. Or the longest running of all if you count by episode instead of by years active. A piper of the Clan McLaren, who came from 18th century Scotland.


 * Ascended Extra: His character wasn't intended to be a companion.
 * Badass: One of the few action oriented companions, and quite keen to get stuck into the action.
 * Battle Cry: "Creag an Tuire!" ("The Boar's Rock", the motto of the McLaren Clan).
 * Brave Scot
 * Fish Out of Temporal Water: To an extent; he was a quick learner.
 * Heroic Sacrifice: One of Jamie's ultimate fates in an Expanded Universe tale penned by Grant Morrison. Many fans were not happy... but most seem to agree that it was a pretty damned badass way to go.
 * Heterosexual Life Partners: He appears in all but the first of Troughton's serials, and this pairing is remembered as one of the best ever.
 * Laser Guided Amnesia: Had all but his first adventure mind-wiped by the Time Lords.
 * Long Bus Trip: Appeared as a companion to the Sixth Doctor's Big Finish adventures 25 years since his last appearance in the series; 41 years since his last appearance as a Companion proper. This must be some kind of record.
 * Man in A Kilt: He's Scottish, what'd you expect?
 * No Sense of Personal Space: Mostly with the Doctor, but sometimes with the female companions as well.
 * The Nth Doctor: "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 -- bringing back Frazer Hines.
 * Security Cling: All the time, especially with the Doctor.

Victoria Waterfield (Second Doctor)
"Second Doctor: You look very nice in that dress, Victoria.

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

Second Doctor: A bit short? Oh, I shouldn't worry about that. Look at Jamie's."

"Played by: Deborah Watling (1967-68, 1993)"

A well-brought-up young lady from 1866. Taken in by the Second Doctor after the Daleks blew up her home and exterminated her father.


 * Break the Cutie: 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 Monster of the Week. According to Deborah Watling, this gradual shift in character was deliberate.
 * Damsel in Distress
 * The Dulcinea Effect: In her first story, she has this effect on Jamie.
 * Fish Out of Temporal Water
 * I Choose to Stay
 * Identical Daughter: She "looks just like" her late mother, and there's a portrait to prove it.
 * Letting Her Hair Down: 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 "The Web of Fear", she even wears a mini-skirt.
 * Proper Lady
 * Punny First Name: Even if it wasn't intentional.
 * Screaming Woman: And how! Her screams are even used to resolve the plot of one serial.

Brigadier Sir Alastair Gordon Lethbridge-Stewart (Second, Third, Fourth, Fifth and Seventh Doctors)
"Just once, I'd like to face an alien menace that wasn't Immune to Bullets."

"Played by: Nicholas Courtney (1968-75, 1983, 1989, 1993)"

Some people consider him a companion, others don't. All acknowledge his significance as a character. The head of UNIT in the 70s (or was it the 80s?), the Brig worked alongside the Doctor and many of his companions in that era and beyond - often defending the Earth from various threats. Retired from UNIT in 1976, though still met up with the Doctor and Sarah Jane (in The Sarah Jane Adventures) on occasion.

"Brigadier: In my day, we took on Daleks, Cybermen, Autons, Zygons, and all manner of space thuggery! And it doesn't come more hostile than that!"
 * Agent Scully: Has a tendency to keep this up even when up to his eyeballs in aliens. First time in the TARDIS, he dismissed the inside view as "some kind of optical illusion".
 * Anti Hero: Type IV. Normally he's clearly on the good team but he dives headlong into this in Doctor Who and the Silurians where he orders the total genocide of a hibernating race, and showed no hesitation about gunning down an unarmed prisoner in Battlefield.
 * Ascended Extra: Appeared as simply Colonel Lethbridge-Stewart in "The Web of Fear". Brought back the next season and given a bonus promotion.
 * Badass Beard: In old age.
 * Badass Mustache: Ironically, a fake one in almost all of his appearances outside "The Five Doctors". This allowed the actor to turn The Brigadier into the "Brigade Leader" in the Mirror Universe tale "Inferno". There, the character sported an Evil Scar-and-Eyepatch combo. Quite jarring.)
 * Badass Normal
 * Beware the Nice Ones: Despite his constant politeness, stiff upper lip and occasional goofy moments he's probably the most ruthless regular character in televised Who canon.
 * The Brigadier: Trope Namer!
 * The Character Died With Him: He is stated to have passed away offscreen in "The Wedding of River Song", Nick Courtney having died a couple of months before Series 6 began.
 * Colonel Badass: Before his promotion to The Brigadier.
 * Cool Old Guy: After he retired.
 * Deadpan Snarker
 * The Eeyore: He can snark and be irritated by the Doctor and whatever catastrophe he now has to deal with, but it's clear that beneath it all, he's secretly having the time of his life.
 * Eyepatch of Power: His scary alternate-universe self in "Inferno".
 * Five Rounds Rapid: Also the Trope Namer.
 * Good Looking Privates
 * Porn Stache: Interestingly, his fascist Mirror Universe counterpart is clean-shaven.
 * The Reason You Suck Speech: In The Sarah Jane Adventures, he gives modern day UNIT one after a Bane disguised as a UNIT major has the cheek to insinuate that his era had it easier.


 * Retired Badass: In SJA, just because he retired doesn't mean he won't remind you of just why he is the Brig.
 * Running Gag: In both Doctor Who and The Sarah Jane Adventures, the Brig has a disturbing tendency to be "stranded in Peru" when all the important, UNIT-related alien stuff is going on.
 * Shoot the Dog: Very much so in Doctor Who and the Silurians.
 * The Snark Knight
 * Stiff Upper Lip: No matter whatever weird menace the Universe throws against him, the Brig takes it completely in stride.
 * You Look Familiar: Nicholas Courtney played Bret Vyon in "The Daleks' Master Plan" before he got the role of the Brigadier, making him the only actor to act alongside all seven (eight if you count the audio drama "Minuet in Hell") of the original Doctors at some point in his career.

Zoe Heriot (Second Doctor)
"My head has been pumped full of facts and figures which I reel out automatically when needed, but I want to feel things as well."

"Played by: Wendy Padbury (1968-69, 1983)"

A teenaged astrophysicist from the 21st century (as seen from 1968). Stowed away on board the TARDIS.


 * Badass Adorable: As seen in 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.
 * Brainy Brunette
 * Emotionless Girl: In her first serial.
 * Though she did seem a little hurt when Leo called her 'all brain and no heart'.
 * Future Spandex: Her uniform in "The Wheel in Space", and her sparkly catsuit in "The Mind Robber" and "The Invasion".
 * Genius Ditz: She doesn't know much history.
 * Good With Numbers
 * Hair Decorations: She always wears an Alice band.
 * Hot Scientist
 * Laser Guided Amnesia: Same as with Jamie, thanks to those Time Lords. Temporarily removed for the odd Big Finish adventure; usually returns.
 * Little Stowaway
 * Long Bus Trip: Much like Jamie above, Zoe is returning to the franchise for a Big Finish 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.
 * Ms. Fanservice: Her sparkly catsuit is particularly fondly remembered, especially that bit in "The Mind Robber".
 * Photographic Memory
 * Real Women Don't Wear Dresses: In "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.
 * Spell My Name With an S: Heriot or Herriot? The original script used the single-R version.
 * Straw Vulcan
 * Teen Genius
 * Vague Age: Depending what source you consult, she's anything from 12 to 21, though Word of God tends towards 15 or 16. The only onscreen mention of her age is in "The Invasion", where the Brigadier estimates it as 19.
 * Waif Fu
 * Waif Fu

Sergeant John Benton (Second, Third and Fourth Doctors)
"Played by: John Levene (1968-75)"

One of two recurring characters during the UNIT years who were subordinate to the Brigadier, Benton was down-to-Earth and often had common sense that others around him seemed to lack. Apparently killed in action by an android duplicate, it turns out that he retired from UNIT in 1979 and has since become a used car salesman.


 * The Fettered: He even lets the Doctor knock him out in Invasion of the Dinosaurs so he doesn't have to break the law to help him.
 * Good Looking Privates
 * Number Two: The Brigadier often confers to Benton when he needs something done, even though Mike Yates outranks him.
 * Only One Name: John Benton was only "Sergeant Benton" until the 1987 spin-off video Wartime, though his first name was decided upon back in the 1970s. The name was simply not used until then, but has subsequently appeared in the Expanded Universe as his name.
 * Rank Up: Happens twice.
 * Sergeant Rock: Eventually became UNIT's Regimental Sergeant Major, and often served as the Brig's senior enlisted man in the field.
 * Those Two Guys: With Yates.

Dr. Elizabeth "Liz" Shaw (Third Doctor)
"Brigadier Lethbridge-Stewart: Nonsense. What you need, Doctor, as Miss Shaw herself so often remarked, is someone to pass you your test tubes, and to tell you how brilliant you are."

"Played by: Caroline John (1970, 1983, 1993)"

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. Eventually got her own debatably canon direct-to-video spinoff, P.R.O.B.E., in 1994.


 * Agent Scully: Initially.
 * Deadpan Snarker
 * Fiery Redhead: She could even out-stubborn the Third Doctor.
 * Hot Scientist
 * Ms. Fanservice: If her penchant for mini-skirts is any indication.
 * Omnidisciplinary Scientist: She holds degrees in medicine, physics, and "a dozen other subjects".
 * Put On a Bus: Left for Cambridge offscreen in Terror of the Autons, apparently dissatisified with her job of "passing the Doctor test tubes". Returned to UNIT and was stuck in the moonbase as of the The Sarah Jane Adventures story Death of the Doctor. Barry Letts apparently didn't like the character, but she was already under contract, which he didn't renew.

Jo Grant (Third Doctor)
"Third Doctor: I thought you said you took science at A-Level.

Jo: I didn't say I passed."

"Played by: Katy Manning (1971-1973)"

Assistant to the Third Doctor during his exile on Earth. Ostensibly a scientist, but it's later revealed that a high-placed uncle got her the job.

""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.""
 * Badass Damsel: By virtue of swinging between Distressed Damsel and Action Girl.
 * Beware the Nice Ones: Incredibly charming, equally disarming.
 * Bunny Ears Lawyer
 * Combat Stilettos: Combat Platforms, really; she spends most of her serials tackling mountains, quarries, and open fields in three-to-four-inch platform boots.
 * Cool Old Lady: In The Sarah Jane Adventures
 * Crouching Moron Hidden Badass: In "The Mind of Evil" most prominently.
 * Cute Clumsy Girl
 * Cute Clumsy Girl


 * The Ditz
 * Escape Artist: 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.
 * Faux Action Girl: Was originally meant to be an 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 Escape Artist. Eventually though it became easier for the writers to portray Jo as The Ditz and Damsel in Distress. In fairness Jo was a rookie -- she'd been trained as a secret agent, but had no experience.
 * Grandma What Massive Hotness You Have: Even Rani points it out! (In The Sarah Jane Adventures)
 * Hair of Gold: She sports the classic 70's "lion-cut" shaggy hairdo.
 * Manic Pixie Dream Girl: A platonic version. Her friendship with the Third Doctor makes him a more open and softer person, and he's noticeably hurt when she leaves him.
 * Ms. Fanservice: 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.....
 * Nice Girl
 * Obfuscating Stupidity
 * Plucky Girl: Not many people can politely tell the Master that they aren't going to let themselves be hypnotized again.
 * The Power of Love: Gigantic invincible intergalactic demon about to wipe out mankind? No problem.
 * Walking the Earth:.
 * The Watson
 * Wide Eyed Idealist
 * Will They or Won't They: She enjoys a mild flirtation with Mike Yates and in "The Curse of Peladon", she's all ready to go out on a date with him, until the Doctor whisks her away.
 * Will They or Won't They: She enjoys a mild flirtation with Mike Yates and in "The Curse of Peladon", she's all ready to go out on a date with him, until the Doctor whisks her away.

Captain Mike Yates (Third and Fourth Doctors)
"Played by: Richard Franklin (1971-74, 1983)"

A recurring character during the UNIT years, Mike Yates was one of several subordinates to the Brigadier over the years. He left UNIT in shame, however, after being brainwashed and forced to assist with the destruction of the modern era with dinosaurs of all things. Yates returned once more for the final Third Doctor tale, but it is currently unknown if he rejoined UNIT after or simply faded into obscurity.


 * Aborted Arc: Franklin currently believes that the original intention of the serial "Invasion of the Dinosaurs" was to kill off Mike Yates. This is indeed quite possible, though his appearance in a subsequent story might suggest otherwise.
 * Ambiguously Gay: Whether or not he's straight, gay, or bi depends both on how you interpret his behavior and on which spinoff material you think is canon.
 * Brainwashed
 * Did Not Get the Girl: Flirted on and off with Jo Grant for his time on the show, and looks utterly crestfallen when she announces her marriage...according to an interview with Richard Franklin, the stage directions actually called for this.
 * Good Looking Privates
 * Those Two Guys: With Benton.
 * Well Intentioned Extremist/Heel Realization:

=== Sarah Jane Smith (Third, Fourth and Tenth Doctors ) ===

"Sarah Jane: So, providing we don't burn up on re-entry and aren't suffocated on the way down, we'll probably be smashed to a pulp when we land.

Fourth Doctor: Exactly. Sarah, you've put your finger on the one tiny flaw in our plan.

Sarah Jane: Our plan? It's your plan!"

"Played by: Elisabeth Sladen (1973-76, 1983, 1993, 2006, 2008, 2010)"

A journalist from South Croydon, who met the Doctor while posing as her virologist aunt Lavinia. Perhaps the most archetypal companion (many older fans grew up with her as their companion), and the longest-serving if you count by number of serials. So popular that she got two spinoffs: the didn't-go-anywhere K-9 and Company (1981), and the much more successful The Sarah Jane Adventures (2007-2011).


 * Brainwashed: Holds the companion record for most times hypnotized. It seemed like she was hypnotized in every episode. Lampshaded in "The Hand of Fear" and The Sarah Jane Adventures.
 * Brick Joke: One that took around 30 years to land. When we last saw her in Tom Baker's day, he'd dropped her off in a place he assured her was Croydon. We find out in David Tennant's time that it was actually Aberdeen, Scotland.
 * The Bus Came Back
 * Cool Old Lady: After "School Reunion".
 * Going for The Big Scoop: She typically runs into danger in order to get the story, especially early on.
 * Grandma What Massive Hotness You Have
 * Hot Scoop: Sarah Jane features highly in the sexy companion polls on a regular basis.
 * Intrepid Reporter
 * Lady of Adventure
 * Older and Wiser: She's become increasingly Doctor-like.
 * Plucky Girl
 * Rummage Sale Reject: The Andy Pandy outfit from "The Hand of Fear".
 * Straw Feminist: In her early appearances; this got toned down later.
 * The Watson

Harry Sullivan (Fourth Doctor)
"Fourth Doctor: Harry Sullivan is an imbecile!!!"

"Played by: Ian Marter (1974-75)"

A brief companion of the Fourth Doctor, the character was brought in just in case the Doctor cast was an elderly Doctor rather than… well… Tom Baker. As such, Harry was fairly redundant in some ways, but the bumbling naval officer is still fondly remembered for his chemistry with Tom Baker and Lis Sladen, making up one of the most memorable TARDIS teams.


 * Badass Normal
 * The Character Died With Him: Implied in The Sarah Jane Adventures.
 * Distressed Dude
 * Informed Ability: He's a doctor, but always seems out of his element. Then again…
 * The Medic: He certainly does a fair bit of harm for someone who's medically trained, though.
 * Mildly Military: He's a Royal Navy Surgeon-Lieutenant, but he rarely ever acts like it.
 * The Nicknamer: Continually referred to Sarah Jane as "Old Thing" and had similar nicknames for other characters.
 * Quintessential British Gentleman: "I say!"
 * Straw Misogynist: Can be pretty sexist and condescending towards Sarah Jane. Although this was deliberate by the production team in order to contrast with Sarah Jane's Straw Feminist traits.
 * You Look Familiar: Ian Marter had a minor part in the Third Doctor serial "Carnival of Monsters" before being cast as Harry.

Leela of the Sevateem (Fourth Doctor)
"Don't worry, Doctor. I found the answer: knife them in the neck!"

"Played by: Louise Jameson (1977-78, 1993)"

A human Noble Savage, descendant of an ill-fated colonization expedition. Primarily remembered for her Fan Service leotard and trying to kill anything that looked hostile - however, though she was (initially) quite ignorant, she was not stupid and made up for her inferior intellect with her own insights and Simpleminded Wisdom.


 * Action Girl
 * Anti Hero: Type III. Unlike the Doctor, Leela doesn't have any qualms about hurting or killing others.
 * Badass: With one of her most notable moments beign when she killed a Sontaran by stabbing its probic vent with a throwing knife.
 * Badass Normal
 * The Bus Came Back: Though Leela gets name-dropped by the Doctor in a couple episodes (and in an "I wonder how Leela's doing" context), she doesn't return for real until the audio plays, notably Zagreus where she teams up with Time Lady President Romana and later go on to star in their own spin-off.
 * Detect Evil
 * Fur Bikini: More precisely, a leather leotard and knee-high boots. Actress Louise Jameson once showed off a letter she received from a young girl viewer asking if Leela would "please wear more clothes". In a scene filmed for the Series 5 DVD release, Amy Pond comes close to uttering the trope name when she asks if Leela (seen in a photograph) is wearing a "leather bikini".
 * I Choose to Stay: She remains on Gallifrey and marries a Time Lord named Andred after the events of "The Invasion of Time."
 * Noble Savage
 * Nubile Savage
 * Only One Name
 * Parent Service: Conceived as such.
 * Psycho Sidekick: She kills or inflicts potentially-lethal violence on quite a number of mooks, and the Doctor's protests often seem only token.
 * Pygmalion Plot: The original idea (without the "falling in love with her" bit).
 * Screaming Woman: Subverted. Hard. She screams exactly once, and that was when a giant mutant rat started chewing on her leg. This does not count war cries.
 * Weapon of Choice: Her knife.
 * What Happened to The Mouse: Her fate in the Time War is unknown.

K-9 (Fourth and Tenth Doctors)
"I am not a dog. I dislike the terms "heel", "sit", and "boy"."

"Voiced by: John Leeson (1977-79, 1980-81, 1983, 1993, 2006, 2008); David Brierley (1979-80)"

The first robot-buddy of the franchise, hailing from the 51st century. Shared a spinoff with Sarah Jane Smith and is a recurring character on The Sarah Jane Adventures, being a regular for series 3. Also got his own Australian-made spinoff, K 9.

"Rose: It looks so...disco.
 * The Cat Came Back: The first K-9 (Mark I) was left with Leela on Gallifrey, the second K-9 (Mark II) was left with Romana II, a third and fourth K-9 (Mark III and IV) were given to Sarah Jane Smith...
 * Badass Automaton; With a dash of Badass Adorable.
 * Catch Phrase: "Affirmative." "Negative." "Master/Mistress?"
 * Do Anything Robot: Laser beam, hacking computers, defensive protocols, beating the Doctor at Chess, being a Deus Ex Machina...
 * Family Friendly Firearm: K-9's ever-convenient laser beam has a kill option, but is always set on stun.
 * The Nth Doctor: Largely subverted in that each K-9 unit is essentially the exact same thing as the previous model (except the version in the K-9 spinoff, which looks drastically different).
 * The Other Darrin: Leeson wound up replaced by Brierly in Season 17 for one reason or another, but came back for the other appearances.
 * Punny Name: Get it? K-9? Because it looks like a dog! K-9! As in CA-NINE.
 * Robot Dog Buddy
 * Think Nothing of It
 * Zeerust: Lampshaded in "School Reunion".

Tenth Doctor: Oi! In the year 5000 this was cutting-edge!"

Romana (1978-81, 1983, 1993) (Fourth Doctor)
"Fourth Doctor: Well, here we are. We've tracked him to his lair.

Romana I: Yes, we've got him exactly where he wants us."

A Time Lord, or more properly a Time Lady, like the Doctor, and therefore has multiple regenerations. (Two were seen onscreen, dubbed Romana I and Romana II by fans; the Expanded Universe added a third.) Sent to assist the Doctor in the search for the Key To Time, she was initially what one would call "book-smart": extremely well-educated (her academic record trounced the Doctor's), but quite young and with little practical experience.

Tropes common to both incarnations

 * Deadpan Snarker
 * Distaff Counterpart: To the Doctor.
 * The Fashionista
 * Hot Scientist
 * Only One Name
 * Overly Long Name: "Romana" is actually short for "Romanadvoratrelundar".

Romana I
"Romana I: You have absolutely no sense of responsibility whatsoever!

The Doctor: What?

Romana I: You're capricious, arrogant, self-opinionated, irrational, and you don't even know where we're going!

The Doctor: Exactly!"

"Played by: Mary Tamm (1978-79)"

A tall, leggy, dark-haired woman; the initial concept of her was a "Grace Kelly" sort of character. Could be called "the skirt Romana", preferring these.


 * Action Girl: occurs unexpectedly in "The Pirate Planet" when she gets into a laser gun fight and wins.
 * Defrosting Ice Queen: She relaxes a lot over the course of her tenure.
 * Love Redeems: The whole thing with the Shadow.
 * Pimped Out Cape: Made of white feathers
 * Put On a Bus: Without actually getting rid of the character. Since she's the same race as the Doctor, she could regenerate and stay on as a character. However, the regeneration comes with basically no explanation and is a lot like a standard Put On a Bus.
 * Rich Bitch
 * Tall Dark and Bishoujo

Romana II
"The Doctor: Psst, you are wonderful.

Romana II: Suppose I am. I've never really thought about it."

"Played by: Lalla Ward (1979-81, 1983, 1993)"

Shorter, with strawberry blonde hair. Preference for trousers rather than skirts.


 * Bifauxnen: At times.
 * Catholic School Girls Rule: Wears a very St Trinian's style uniform in the "City of Death" serial. Lalla Ward, judging by interviews and the production notes, came up with the idea and had no concept it was a fetish.
 * Expanded Universe: several novels and audio dramas have attempted to explain why Romana regenerated into the Lalla Ward version. These range from the short story "The Lying Old Witch in the Wardrobe" suggesting the TARDIS forced her to in a fit of jealousy (after impersonating Romana during the events of Destiny of the Daleks), to other ideas.
 * Gendered Outfit: Wore a pink version of The Doctor's outfit.
 * I Choose to Stay: After three serials of trying to get out of E-Space, she decides to stay at the end of "Warriors' Gate" to help a race of enslaved time-traveling lion people.
 * Lady of Adventure: More keen on adventuring than her first incarnation.
 * Nerves of Steel: An adventurous Time Lady like her picked them up really quickly after jousting against The Daleks
 * Never Found the Body
 * Romance On the Set: With Tom Baker.
 * Sorting Algorithm of Deadness: She gets a 1.833333.
 * Wholesome Crossdresser: Although she just likes men's clothes rather than actually being a transvestite. Described in one DVD extra as the only woman who could pull off wearing a fruit salad on her head.
 * You Look Familiar: The actress was a guest star as Princess Astra of Atrios in the story immediately preceding her debut. This was referenced in-story as Romana choosing that form to regenerate into.

Adric (Fourth and Fifth Doctors)
"Could anyone pass the sodium chloride, please?"

"Played by: Matthew Waterhouse (1980-82)"

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. He is most notable for being the longest serving companion to be killed off.


 * Anti Hero: Type II
 * The Artful Dodger: It's even part of his character concept.
 * Berserk Button: Adric puts a girl in a stranglehold for trying to take his math badge. In his first scene.
 * BFG: Used for a very weakly executed but surprisingly effective one-man Big Damn Heroes moment near the end of "Warriors' Gate."
 * Bizarre Alien Biology: In addition to his Healing Factor, the Companion Chronicles reveal that Alzarians' hearts are on the right side of their chest cavity.
 * Dead Older Brother: Varsh. He keeps his belt as a memento.
 * Dying Alone: On a crashing spaceship, thinking he just failed to save the world.
 * Fake Defector: And HOW. Considering he does this three times over the course of his time in the TARDIS ("State of Decay", "Castrovalva," and "Kinda"), it's not surprising that a lot of fans accuse him of "always siding with the villain."
 * Famous Last Words: "Now I'll never know if I was right..."
 * A God Am I: In Big Finish's The Boy That Time Forgot. Courtesy of applied mathematics, timey-wimey stuff, and alien technology that helps Adric bend an alternate reality to his will.
 * Good With Numbers
 * Guile Hero
 * Heroic Sacrifice: Or it would have been, had it actually achieved anything.
 * Senseless Sacrifice
 * The Expanded Universe audio adventures by Big Finish did wind up giving him one, though.
 * Healing Factor: You'd think it'd be a massively useful trait for a companion to have, given the scrapes they get into, but Adric's Healing Factor is only mentioned twice - in "Full Circle" (his introductory story) and again in "The Visitation".
 * Horrible Judge of Character: Towards Monarch in "Four to Doomsday." Turning the entire population of Earth into androids to rid them of disease sound like a good idea to you?
 * Human Aliens: Adric's species has three forms, only one of which is humanoid.
 * Iconic Item: His mathematical excellence badge. Seeing it shattered on the floor of the TARDIS at the end of "Earthshock" makes the Silent Credits all the more powerful.
 * Informed Ability: For a supposed genius, Adric doesn't come off as being particularly intelligent.
 * Insufferable Genius: Most fans place the emphasis firmly on 'insufferable'.
 * Jerk With a Heart of Gold: To an extent. The "jerk" part doesn't really emerge until season 19, but ultimately he still cares.
 * Little Stowaway: how he got on the TARDIS in the first place.
 * Love Makes You Crazy: In The Boy That Time Forgot, he tells Nyssa that he had the entire City of Excellence built so that he could bring her back to him and make her his bride.
 * Mr. Vice Guy: Driven by a desire for approval and acceptance.
 * New Powers As the Plot Demands: Ability-wise, Adric is a surprisingly well-equipped companion, demonstrating proficiency in lock-picking, sleight-of-hand, and knife-throwing, amongst other things. The catch? Most of them only get used in one story, two if it's really lucky.
 * The Other Darrin: Adric was played by Andrew Sachs in The Boy That Time Forgot because Matthew Waterhouse didn't want to work for Big Finish.
 * This will apparently be the case for any subsequent appearances of Adric as Waterhouse has stated that him returning to the role would be "ridiculous" by this point, even for audios, seeing as he was 18 when he played him and is pushing 50 now.
 * Promoted Fanboy: Matthew Waterhouse had a letter published in Doctor Who Magazine mere weeks before he was cast as Adric.
 * Reality Subtext: Adric's older brother Varsh dies in "Full Circle," just two years after Matthew Waterhouse's own older brother Nicholas had commited suicide.
 * Teen Genius
 * Took a Level In Badass: His TARDIS-induced cameo in the comic The Forgotten: Saves the Doctor from one of the clockwork robots from "The Girl in the Fireplace." By throwing himself at it and blowing it up. With a can of Ace's Nitro-9. And he goes out smiling.

Nyssa of Traken (Fourth and Fifth Doctors)
"Do you have any books on telebiogenesis?"

"Played by: Sarah Sutton (1981-83)"

Daughter of Tremas, who got his body possessed by the Master at the end of Fourth Doctor serial The Keeper of Traken. Famous for the skirt removal bit in Terminus, which the actor herself has described as "a gift to the fans". One of the more accomplished TARDIS pilots among the companions; she was even able to fly it solo (with assists from Tegan in Castrovalva and Adric in The Visitation).


 * Eighties Hair
 * Angst What Angst: The implications of her tragic backstory are barely mentioned in the show, but the Expanded Universe would make use of all her emotional baggage.
 * Ascended Extra: Was never intended to be a companion, until producer John Nathan-Turner decided otherwise.
 * Beware the Nice Ones: "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.
 * Brainy Brunette
 * The Bus Came Back: She rejoins Five, Tegan, and Turlough for a few audio adventures 50 years later (for her) and immediately after the events of "Enlightenment" (for them).
 * Women Are Wiser
 * Died in Your Arms Tonight: In her Companion Chronicle The Darkening Eye. With Tegan.
 * Expanded Universe: In the Big Finish audio series, teenaged Nyssa travels for a long time with the Doctor (presumably between the TV stories "Time-Flight" and "Arc of Infinity", during which interval Tegan as been kicked to the curb). Later, she rejoins the Doctor at a period after "Terminus", but
 * Giant Poofy Sleeves
 * Hot Scientist
 * Human Aliens
 * I Choose to Stay: She leaves the TARDIS crew to stay on Terminus and try to restructure it into a proper hospital.
 * Innocent Aliens
 * Last Of Her Kind: The rest of Traken died in "Logopolis".
 * Nice Girl
 * Odd Friendship: With Tegan, who is almost her polar opposite.
 * Plucky Girl
 * Pretty in Mink: One of her outfits had a fur-trimmed jacket
 * The Quiet One: In comparison to Adric and Tegan.
 * Teen Genius

Tegan Jovanka (Fourth and Fifth Doctors)
"Fifth Doctor: How do you feel now?

Tegan: Groggy, sore, and bad-tempered.

Fifth Doctor: Almost your old self, then!"

"Played by: Janet Fielding (1981-84)"

A brash Australian, 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.


 * Eighties Hair: The short, Sheena Easton variety.
 * Beam Me Up Scotty: Tegan's supposed fondness for using "Rabbits!" as a swear word. She actually only uses it twice.
 * The Cat Came Back: 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 (by accident).
 * Demonic Possession: Guess who becomes the Mara's host both times it shows up?
 * Department of Redundancy Department: "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?!"
 * Line of Sight Name: How the character was named. Nathan-Turner was either going to choose Tegan, for an Australian friend's niece, or Jovanka, after the wife of Yugoslavian president Josip Broz Tito. Script-editor Christopher H. Bidmead read Tegan as the first name and Jovanka as the last name. The rest, as they say, is history.
 * Odd Friendship: With Nyssa.
 * Plucky Girl
 * Sexy Stewardess
 * Tsundere: Heavily Type A, the deredere being nearly vestigial.
 * Vitriolic Best Buds: Type 2 with Adric. They seem to care as much as they bicker, especially when one of them gets captured (or killed).

Vislor Turlough (Fifth Doctor)
"What is it about Earth people that makes them think a futile gesture is a noble one?"

"Played by: Mark Strickson (1983-84)"

An alien noble exiled to Earth after a revolution on his planet, Turlough is posing as an English schoolboy when the Doctor meets him. 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.


 * Anti Hero: Type IV
 * Awesome McCoolname
 * Chivalrous Pervert: He even gets some in various Expanded Universe tales. Lord knows it'd never happen on camera.
 * Deadpan Snarker: Particularly towards Tegan, who's just as capable of snarking right back.
 * Deal With the Devil
 * Distressed Dude: Done often because the writers couldn't figure out what to do with Turlough.
 * Fan Service: He sure took a lot of clothes off in "Planet of Fire"...
 * Heel Face Turn: He starts out plotting to kill the Doctor for the Black Guardian, but eventually becomes the Doctor's loyal friend.
 * Thicker Than Water
 * Token Evil Teammate: 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.
 * Human Aliens
 * Last Name Basis
 * Long Lost Sibling
 * Mark of Shame
 * The Mole: Initially.
 * Mysterious Past: And we learn what it is in his final episode.
 * Redheaded Hero: John Nathan-Turner insisted that the naturally blond Mark Strickson dye his hair ginger so as not to be confused with Peter Davison in long shots.
 * Shirtless Scene: Actually, more like a male Wet Sari Scene - with speedos.
 * The So Called Coward

Kamelion (Fifth Doctor)
"Unexpected as it may be, I do have a mind of my own."

"Voiced by: Gerald Flood (1983-84)"

A shape-changing robot that the Master acquired as a sort of souvenir from the planet Xeriphas, this character quite literally vanished into the TARDIS rather than becoming a Companion, and is almost always forgotten. This, in itself, is not necessarily a bad thing. Showed up in "The King's Demons" as a villain and puppet of the Master, got cut from an appearance in "The Awakening" and made a final appearance in "Planet of Fire".


 * Dropped a Bridge On Him
 * Expanded Universe: Actually fleshed-out in several novels.
 * Forgotten Fallen Friend: Never mentioned again, whatsoever.
 * We Hardly Knew Ye
 * Mercy Kill: The less said about this one, the better.
 * Punny Name
 * Robot Buddy: Literally.
 * Shapeshifting
 * Shoo Out the New Guy: 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 Dropped a Bridge On Him.
 * Suspiciously Similar Substitute: Was conceived as a successor to K-9, just not looking like a dog.
 * Weak Willed: Very easily manipulated by the willpower of others.

Perpugilliam "Peri" Brown (Fifth and Sixth Doctors)
"The Master: I am the Master!

Peri: So what? I'm Perpugilliam Brown, and I can shout just as loud as you can!"

"Played by: Nicola Bryant: (1984-86)"

The series' only regular American companion (supposedly), Peri was a botany student who stumbled into the TARDIS while she was on holiday. Has developed a lot of attention from male fans due to her tendency to wear tight clothes.


 * Eighties Hair
 * Abhorrent Admirer: Peri has an unfortunate knack for attracting lustful weirdos, such as Sharaz Jek and the Borad.
 * Abusive Parents: She has a nightmare about her step-father in her first appearance: fans were left to draw their own (generally unpleasant) conclusions.
 * In at least one bit of the Expanded Universe, it's canon that she was molested as a child. Break the Cutie indeed.
 * Absolute Cleavage: Just ask Peter Davison. Some of her wardrobe is actually modest though.
 * Break the Cutie: The Expanded Universe 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 "perfect" example deals with the alternate possibilities coming from her final appearances. . Not only does the EU like screwing with Peri, but Big Finish likes messing with continuity.
 * The Ditz: Season 22, mostly. Luckily, she improved drastically in her last season, not to mention her audio adventures.
 * Form Fitting Wardrobe
 * Know Your Vines: Peri is a botanist, but rarely gets the opportunity to show it.
 * Male Gaze: Her introduction.
 * Ms. Fanservice: 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 really cold.
 * Ooh, Me Accent's Slipping: A lot. Really hard. To the point that some American viewers have had to Google her to figure out where she was meant to be from.
 * The accent was also problematic because the production team had Nicola Bryant present herself as being an American just like Peri.
 * Parent Service: Another blatant example like Leela before her.
 * Plucky Girl
 * Shouldn't Peri Be Back In School Right Now?: Depending on what her fate really is. See the alternate possibilities above.
 * Tsundere: A Type B with the Sixth Doctor. Also an example of Vitriolic Best Buds (Type 2).

Melanie "Mel" Bush (Sixth and Seventh Doctors)
"AAAIIIIIIIEEEEEEEEEEEEEE!!!"

"Played by: Bonnie Langford (1986-87)"

A computer programmer from Brighton, Mel was well known both for having a particularly piercing scream and being obsessive about her health (and the Doctor's, for that matter).


 * Eighties Hair
 * Characterization Marches On: Her obsession with the Doctor's health. Possibly justified as he did end up changing physically, just not in a way she expected.
 * Fiery Redhead: Without the typical fighting capability.
 * Giant Poofy Sleeves
 * I Choose to Stay: With Sabalom Glitz, for some reason.
 * Informed Ability: Mel supposedly had a Photographic Memory, but this never came up.
 * Love Freak: In the audio play The Juggernauts she tries to redeem Davros. Of course, she doesn't exactly have the long history with him the Doctor has, but still...
 * Beware the Nice Ones: Just don't piss her off, really.
 * Make Me Wanna Shout: Possible real-world example; it has been mentioned that she was hired because she had a scream "that could tear the paint off walls". It's not far from the truth.
 * Nice Girl
 * No Indoor Voice
 * No Name Given: 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 made "official" in the Expanded Universe.
 * Screaming Woman: And how! The actress was hired for her scream which could "tear the paint off walls".

Dorothy, aka "Ace" (Seventh Doctor)
"Seventh Doctor: I don't believe you've met my young friend Ace, an expert in calorification, incineration, carbonization , and inflammation."

"Played by: Sophie Aldred (1987-89)"

A "typical" 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.

"Seventh Doctor: "ACE! Hand me some of that Nitro-9 you're not carrying.""
 * Eighties Hair
 * Aborted Arc: According to Word of God, 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. Oh yes.
 * Her eventual fate is finally alluded to in the Sarah Jane Adventures. When listing what her research has revealed about various companions, Sarah Jane mentions a woman named Dorothy who runs a charity called A Charitable Earth which has raised billions.
 * Anti Hero: Type II
 * Badass: She once beat up a Dalek. With a baseball bat. Inspired the Crowning Moment of Awesome trope.
 * Action Girl
 * Badbutt
 * Broken Bird: The girl had "issues".
 * Butch Lesbian: According to writer Rona Munro, anyway. Ace occasionally has chemistry with male guest stars (notably Captain Soren in "The Curse of Fenric"), but it's much more common with the ladies.
 * Catch Phrase: Enjoyed shouting "Ace!" (meaning "cool"). Since this is also her nickname, it almost seems like she is engaging in Pokémon Speak.
 * She said "Wicked!" so often that the Doctor himself was inspired to say it once.
 * Dark and Troubled Past: The epitome of this trope, to the point where the type of Doctor Ace really needs is a therapist.
 * Expanded Universe: has established that her full name is Dorothy Gale McShane.
 * Girl of the Week: The children's TV Word of Gay version. Ace appeared in nine stories, and rapidly established a close friendship with an attractive young female character in at least five of them.
 * Gosh Dang It to Heck: Much of the Totally Radical comes from the writers' attempts to have her insult people or express emotion without swearing.
 * Mad Bomber: She's very quick to whip out those homemade explosives of hers. The Doctor is more than aware of this.


 * Meaningful Name: Her name's Dorothy, and she ends up in the future by a "time storm". Does this remind you of anything?
 * Taken further via Word of God: her middle name is "Gale".
 * The Nicknamer: She's best known for calling the Doctor "Professor", but she invented names for other characters as well. Mel ended up as "Doughnut".
 * No Name Given: Her surname is not given in any canon source, but audios use Dorothy Gale McShane.
 * Psycho Sidekick: Subverted, 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 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.
 * Really Gets Around: Not on television, but in the Expanded Universe books, Ace seems to shag someone in every novel.
 * Stable Time Loop: She meets her grandmother, causing her own existence.
 * Supporting Protagonist: 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
 * Totally Radical: Try and listen to some of the dialogue and the slang she uses without cringing. Go on. We dare you.
 * Weapon of Choice: Explosives!
 * Wholesome Crossdresser: In Ghost Light.

Dr. Grace Holloway (Eighth Doctor)
"Doctor, I only have one life. Can you try to keep that in mind?"

"Played by: Daphne Ashbrook (1996)"

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

""I finally meet the right guy... and he's from another planet!""
 * All Love Is Unrequited


 * At the Opera Tonight: She's attending the opera when she's called to operate on the Doctor.
 * Brainwashed and Crazy: Due to being hit by the Master's poison/acidic saliva.
 * Black Eyes of Evil: When she's possessed by the Master's influence.
 * People Puppets
 * The Doctor Wants Redheads: And likes snogging them.
 * Hospital Hottie
 * Nice Job Breaking It Hero: Her attempt to save the Seventh Doctor was the cause of his death, forcing him to regenerate into Eight.
 * No Hugging No Kissing: Forever averted. She and the Doctor happily make out.
 * Redheaded Hero
 * Refusal of the Call: Ultimately, she decides not to go with the Doctor, and the Doctor refuses to stay on Earth with her.
