- Bernice Summerfield
- Iris Wildthyme
The vast majority of the companions who showed up in the Doctor Who TV series have returned for the Big Finish audio adventures, played by the original actors. (With the notable exception of Dodo, who has not appeared at all.) Although they usually travel with the Doctor, some just appear together in Companion Chronicles for their own adventures, or in their own separate series. For general character tropes about these returning companions, see the classic series companions page.The companions listed here are sorted in chronological order, by their first time meeting the Doctor in the TV series.

Susan Foreman, later Susan Campbell
Susan Campbell (First and Eighth Doctors)
Voiced by: Carole Ann FordAside from appearing in plenty of Companion Chronicles with the First Doctor, Susan returns as a companion to the Eighth. She's had a busy 20-odd years since her grandfather left her with freedom fighter David Campbell. She raised a half-human son, Alex, and rose high in Earth's fledgling government. Later winds up helping the Earth adjust to the concept of working alongside aliens... and fighting Daleks. Again.
- Break the Cutie: A second Dalek invasion, just like the first... but far worse, losing her son to the Daleks in said invasion and her entire life is ruined in the span of two audio dramas. But despite all she's lost, Susan is more worried about her grandfather's mental state than herself.
- Cloning Blues: In the alternate timeline of "A Storm of Angels", it turns out that the Doctor has made a simulacrum of her to keep him company. When the two Susans meet, the proper Susan, who was still living on Gallifrey, becomes a Defector from Decadence as the two decide to switch places.
- Give Him a Normal Life: Susan doesn't give up her son, but she does pretend to be human for his sake.
- Mama Bear: She's this to her son Alex.
- Reasonable Authority Figure: Both on planet Earth in its regular timeline, and in the alternate timeline of "Auld Mortality"/"A Storm of Angels", in which she becomes Lady President of Gallifrey.
- Shipper on Deck: The Companion Chronicle "Here There Be Monsters" opens with her talking about how she thinks that Ian and Barbara truly belong together.
The TARDIS (All Doctors)
Voiced by: Nicholas Courtney (2003)Sexy Thing gets A Day in the Limelight on occasion in Big Finish, and saves the world a few times over in the process.
- A Form You Are Comfortable With: She projects herself as the Brigadier (and, sort of, as the Third Doctor).
- Armor-Piercing Question: Delivers one to the Doctor:And what is your idea of friendship, Doctor? I’d really like to know.
- Arson, Murder, and Jaywalking: After a while, she gets just a bit fed up with the Doctor's emotional turmoils, his Chronic Hero Syndrome, the strays he brings home, and his terrible taste in music.
- Distressed Damsel: Most notably in "Wirrn Dawn" and "The Fires of Vulcan".
- Fate Worse Than Death: Faces one in "Zagreus". She's not in the mood for it.
- The Jailer: Is forced to become the proverbial can for Sealed Evil in a Can Zagreus.
- Like an Old Married Couple: Mel notes that the TARDIS' symbiotic link with the Doctor is pretty much a marriage. (She's right, of course.)
- New Powers as the Plot Demands: On a few notable occasions, she grows new appendages just to save the Doctor's life.
- Not Herself: In "Zagreus", it turns out that Zagreus has merged with her.
- Patchwork Map: Her library contains an orchard, and her mountain range is a short walking distance from the kitchen.
- What the Hell, Hero?: Towards the Doctor, after he refuses to sacrifice his companion's life to save all of reality... but has no problem with sacrificing the TARDIS and himself to do exactly that. She calls him out on it, hard.
Voiced by: William RussellHaving spent a long time travelling with the First Doctor, Ian has many, many stories to tell. Now much older, he fondly looks back on his adventures.
- Flash Back: His stories in general, since William Russell's voice wouldn't be able to pass for young Ian anymore.
- Relationship Upgrade: "The Rocketmen" chronicles the exact moment he fell in love with Barbara. Literally. Out of a World in the Sky at terminal velocity.
- The Slow Path: Averted in "The Revenants", when he and Barbara manage to reach the 1950's, but can't bring themselves to live out the years in quiet solitude until they'd reach their own timeline again. They choose to go back to the TARDIS instead.
General Sir Alistair Gordon Lethbridge-Stewart
General Sir Alistair Gordon Lethbridge-Stewart (Sixth and Eighth Doctors)
Voiced by: Nicholas CourtneyNow retired and Happily Married to Doris, the Brigadier (or the General, although he prefers being called the former) still works with UNIT at times. He notably also stars in several Unbound stories, many Companion Chronicles, and in a few Big Finish UNIT episodes (without the Doctor).
- Jumped at the Call: In two "what if?" Unbound stories, he's very happy to become the Doctor's companion. Aside from having a pub in Hong Kong, owing to a disastrous career at UNIT, he really has nothing holding him back.
- Retired Badass: Altough she is rather old and retired, the UNIT series see him leading a covert operation to save Britain from total anarchy. The Unbound story "Masters of War" has him putting that experience to good use, despite having been forcibly retired.
- 10-Minute Retirement: He signs back on with UNIT, as a scientific advisor, when he realises he can never truly bring himself to leave.
- Vitriolic Best Buds: Interestingly averted: due to Six's straightforward attitude and Eight's kindness, he gets along noticably better with Six and Eight than he ever did with Two, Three, Four and Seven in the TV series. The Unbound version of him has this relationship with the alternate Third Doctor as well.
- What Happened to the Mouse?: Doris isn't mentioned anywhere in the Unbound audios that Lethbridge-Stewart is in. Judging by how bad things turned out in that universe, it's likely she died from the disasters or divorced him from the fallout said disasters had on his career.
Zoe Heriot (Second Doctor)
Voiced by: Wendy PadburyWhen Zoe parted from the Second Doctor, the Time Lords erased Zoe's memory of her adventures. But certain parties have evidence that she travelled in time, and have tracked her down in search of the information she doesn't know she knows.
- Catch-Phrase: "I remember everything — and I remember nothing."
- Wistful Amnesia: She knows she's lost something, and it's damaged her ability to connect with people.
Josephine "Jo" Grant (Third Doctor)
Voiced by: Katy ManningJo has plenty of Companion Chronicles with the Third Doctor set during their time at UNIT, and a few set many decades later.
- Identical Stranger: Jo looks and sounds exactly like Iris. This is never acknowledged by anyone, Rule of Funny being in full effect.
- Morality Pet: Jo acts as the best version of herself when she travels with Iris Wildthyme. Though hardly a villain, Iris indulges in Jo's more upright views, paying for clothes instead of shoplifting and not drinking quite so much while driving the bus. That said, Jo doesn't mind the parties and fun that Iris brings - she just doesn't want it to be all partying.
- Noodle Incident: Apparently, Jo and Three like to go out ballroom dancing on Saturday nights with Benton.
Captain Mike Yates
Captain Mike Yates (Third Doctor)
Voiced by: Richard FranklinMike appears in a few Companion Chronicles, the third instalment of "Destiny of the Doctor", the second half of "The Worlds of Doctor Who" and in "The Third Doctor Adventures". Though he was previously part of non-Big Finish Doctor Who audio episodes by BBC Audio, they were given a mention in "The Worlds of Doctor Who", which is part of Big Finish canon after Big Finish acquired BBC Audio's properties.
- The Atoner: He has come to regret his betrayal of UNIT, and has not only managed to work his way back into their trust but helps Ruth Matheson and Charlie Sato into good standing as well.
- Canon Welding: Initially, Yates had a significantly greater presence in non-Big Finish Doctor Who audio episodes, accompanying Tom Baker's Fourth Doctor (and housekeeper Mrs Wibbesey) in the "Hornets' Nest", "Demon Quest" and "Serpent Crest" trilogy by Paul Magrs. Mrs Wibbesey was then given mention in "The Screaming Skull" during a probe of Mike Yates' mind, keeping Magrs' series in continuity with Big Finish.
- Easily Forgiven: Zigzagged; he had to work long and hard to get back into his position at UNIT, what with the business with the dinosaurs and all. The Sixth Doctor, though a bit disappointed to be meeting Mike in the ruins of his old laboratory, doesn't seem to hold the past against him.
- Naďve Newcomer: "Vengeance of the Stones" is the story of how he met the Doctor, stopped an alien invasion and joined UNIT.
- Rank Up: He starts off his introduction story as a Lieutenant.
- Real Life Writes the Plot: Richard Franklin is the only member of the UNIT team still alive and willing to work with Big Finish; consequently, Mike is more or less promoted to companion status in "The Third Doctor Adventures".
- Took a Level in Kindness: The experiences since his betrayal has led him to shed his jerkass tendencies, leading to him becoming a better man and soldier.
Sarah Jane Smith
Sarah Jane Smith
Voiced by: Elisabeth SladenPrior to her reappearance on Doctor Who and later, The Sarah Jane Adventures, Big Finish gave Sarah Jane her own two season series. Has its own trope page: Sarah Jane Smith.
- Actor Existence Failure: She would have teamed up with the Fourth Doctor when Tom Baker finally agreed to do audios, but Elisabeth Sladen passed away too soon.
- Real Life Writes the Plot: The creation of The Sarah Jane Adventures meant that Big Finish couldn't use the character any more. When Tom Baker came on board, Nick Briggs received permission from Russell T Davies to use Sarah for the first series of The Fourth Doctor Adventures, but Elisabeth had to quietly drop out after falling ill.
K-9 (Fourth (regular) and Eighth Doctors (guest))
Voiced by: John LeesonK-9 travels with the Doctor, Leela, then Romana, but has on occasion been relegated to looking after the TARDIS while his human friends go out exploring. He eventually joins back up with Leela and Romana in the Big Finish spinoff Gallifrey and the tropes he exhibits in that series can be found there. On one occasion, both K-9 and Romana, after establishing themselves on Gallifrey, rejoin with the Doctor for a once-off adventure involving Professor Chronotis.
- The Comically Serious: Sarcasm is completely lost on him, and would react to snarky remarks from the Doctor and his other companions at face value. Hilarity frequently ensues.
- Brainwashed and Crazy: K-9 in Return to Telos when under Cyber-control.
- Grand Theft Me: He's temporarily taken over by Zodaal in "The English Way of Death".
- No Social Skills: He's basically a talking calculator on wheels and the one thing going for K-9 is that everyone thinks he's cute.
- Not Now, Kiddo: A running gag with the Fourth Doctor, who'd tell K-9 to be quiet just before k-9 has something important to tell him.
- One Steve Limit: Discussed with the Doctor, when he gets very confused as to why K-9 refers to both The Doctor and The Master as "Master". He tells K-9 to call The Master "The Renegade".
- Only Sane Man: Likes to think of himself as this, but his complete lack of understanding humans leads to very awkward (and funny) situations, and averts this trope.
- Sliding Scale of Robot Intelligence: Frequently displays Level 4 abilities in episodes like "Requiem for the Rocket Men", where he's able to do dozens of mathematical equations simultaneously in his head while assisting the Doctor in about three other difficult tasks.
Leela of the Sevateem
Leela of the Sevateem (Fourth, Sixth and Eighth Doctors and at some point, the War Doctor)
Voiced by: Louise JamesonLeela travels with the Fourth Doctor in stories set between their TV series episodes. Later, living on Gallifrey, she meets the Eighth Doctor and Romana during their battle with Eldritch Abomination Zagreus. She and Romana subsequently get their own Big Finish spinoff, Gallifrey — which has its own character sheet — and during that time, she travels back to Victorian London to team up with Jago and Litefoot for many adventures.
- Awesomeness by Analysis: Leela only has to use a weapon once to be an expert and she handles a gun proficiently after using one to protect her friends Jago and Litefoot in "The Talons of Weng-Chiang."
- Unusually Uninteresting Sight: She's not even remotely surprised when, at one point, the day is saved literally by the use of applied nonsense. After all, everything the Doctor does looks like nonsense to her.
- Weak-Willed: Relatively speaking. As a human, she's much weaker against Mind Control than Gallifreyans, which her enemies gladly make use of.
Professor George Litefoot
Professor George Litefoot (Fourth (guest) and Sixth Doctors)
Voiced by: Trevor BaxterThe pathologist from "The Talons of Weng-Chiang" got his own Companion Chronicle together with Jago, followed by many seasons of their own spinoff, which end up also starring Leela. They also encounter the Doctor again on occasion.
- Ambiguously Gay: Very gently hinted that he might be gay, in addition to him being a strong advocate for equal social rights in regards to the love that dare not speak its name.
- Science Hero: A man of science from the Victorian era. He's not bad with the supernatural either, such as the time that the barmaid Ellie became a vampire.
Henry Gordon Jago
Henry Gordon Jago (Fourth (guest) and Sixth Doctors)
Voiced by: Christopher BenjaminThe impresario from "The Talons of Weng-Chiang" got his own Companion Chronicle together with Professor Litefoot, followed by many seasons of their own spinoff, which end up also starring Leela. They also encounter the Doctor again on occasion.
- Large Ham: One does not work in the theatre without being bombastic as can be.
- Manly Tears: Unlike Litefoot, who sees death every day, Jago does not cope well with actual adventures at first and he oftentimes cry.
- Quintessential British Gentleman: Like Litefoot, Jago can be quite the gentleman, although perhaps a bit more brusque.
- These Hands Have Killed: After the first time he has to murder a sapient monster, he feels guilt-ridden.
Romanadvoratrelundar (Fourth (as a regular), Fifth, Sixth and Eighth Doctors (as guest))
Voiced by: Mary Tamm (first regeneration), Lalla Ward (second regeneration), Juliet Landau (third regeneration)Romana travels with the Fourth Doctor when she's in her first body, exploring the universe together with him. In her second regeneration, she becomes the Lady President of Gallifrey, just like in the novels. After a few stories with the Eighth Doctor, Romana II got her own spin-off (Gallifrey) together with Leela, which has a separate character sheet. A new incarnation of Romana voiced by Buffy alumnus Juliet Landau was introduced in 2013.
- Actor Existence Failure: Mary Tamm died before her audios with Tom Baker were published.
- Break the Cutie: Gets thoroughly broken while she's imprisoned by the Daleks, though she recovers marvellously.
- Fan Fic: Spends her spare time as Lady President writing a rather transparent Doctor Fan Fic, about a man named "Sigma".
- Mercy Kill: In "Zagreus", Romana is fully prepared to perform one on Eight.
- The Slow Path: She spends twenty years as a slave for the Daleks.
Voiced by: Matthew Waterhouse, and briefly by Andrew Sachs (2008)Matthew Waterhouse initially refused to return for Big Finish, so for a re-interpretation of the character post-"Earthshock", a much older Adric was played by Andrew Sachs. It would take another five years before Waterhouse eventually joined the cast, and many stories with Adric set during his TARDIS travels have been produced since then.
- A God Am I: God-king of the prehistoric bug people.
- Back for the Dead: He spends his final moments helping Thomas Brewster.
- Only Mostly Dead: Turns out he survived the end of "Earthshock".
- Stalker with a Crush: Spending decades of his life on prehistoric Earth, without any humanoid women around, led him to become a bit... preoccupied with the memory of Nyssa.
Nyssa of Traken
Nyssa of Traken (Fifth Doctor)
Voiced by: Sarah SuttonThe most prolific companion of the Big Finish line, Nyssa has many, many adventures with the Doctor that are set between "Time-Flight" and "Arc of Infinity". She would also encounter the Doctor and her friends again much, much later on in her life — despite it being only two days later for them. Luckily, as she's not human, this isn't as much of a problem as it could be.
- Action Mom: She ends up settling down, and having three children, while still going out on adventures to stop the Company.
- The Bus Came Back: She rejoins Five, Tegan, and Turlough 50 years later (for her) and two days after the events of "Enlightenment" (for them).
- Burn the Witch!: As one of few people to ever leave their Arcadia, Nyssa falls under suspicion by the old world Trakenites who believe she's tainted by their version of the devil. Not that she was that safe on Earth: In "Winter For the Adept", the headmistress of Tremayne Academy is insistent that Nyssa is a succubus. In "The Land of the Dead", she picks up a psychic impression from still-living dinosaur skeletons in Alaska; the superstitious dig team mistakes it for a genuine premonition, and Nyssa is tied up and offered to the "spirits" as sacrifice.
- Calling Me a Logarithm: In "Winter For the Adept", she has this reaction to the Tremayne headmistress labeling her a "harlot". "Whore of Babylon" draws yet another blank.
- Can't Stay Normal: Defied in Nyssa's case. She considers pursuing a simple life with Andrew, the boy she met in Stockbridge. Torn between her responsibilities as a scientist and the anxieties of a linear existence, Nyssa decides she can't cope and leaves in the TARDIS. However, "Circular Time" reveals that she does eventually marry a professor named Lasarti, with whom she has two daughters and a son.
- Character Aged with the Actor: Nyssa's Plot-Relevant Age-Up was essentially done so Sarah Sutton could play a Nyssa who was much closer to her own current voice rather than a voice she had in the eighties. A rejuvenation was also given to the character a few adventures later so her running around with the rest of the TARDIS crew would be much more plausible.
- Character Focus: "Circular Time" is a sweet, almost dreamy character study of Nyssa.
- Dead Guy Junior: Her youngest son is named Adric Traken, after her friend and planet both.
- Died in Your Arms Tonight: In Tegan's. (She gets better.)
- Exposed to the Elements: Nyssa gets a rude awakening one night when the Doctor's teleport experiment sends her somersaulting down the Swiss Alps in her nightgown. She didn't see the humor in it.
- Finishing Each Other's Sentences: With the Doctor, frequently. "The Land of the Dead" suggests that Five just brings it out in people.Doctor: You know, I chide Nyssa for finishing other peoples' sentences but—
Monica: It's quite fun, isn't it?
- Germanic Depressives: Like all Trakenites, she tends toward humorlessness, blank expressions, and pop culture isolation. Stuck in Hamburg without the TARDIS translating for her in "Fanfare For the Common Men", she begins to grow fond of the German language.
- How Unscientific!: Alien activity Nyssa can accept. Telekinesis and energy waveforms, for that matter. But ghosts in "Winter For the Adept"? Sorry, there's just no scientific basis for that.Nyssa: I can't believe you're saying he's a ghost!
Doctor: He isn't! He's a floating cloud of energy which has the power to focus itself and move physical objects, often with dramatic results!
- Hugh Mann: Nyssa never gets the hang of the whole 'incognito' thing. In "Spare Parts", a cyber-nurse (or "Sisterman") radios in to report a suspect, and lists her "possibly bogus" alias as Nyssa O'Traken. Similarly, when Nyssa tells Andrew Harper in "Circular Time" that she is from Traken, he assumes from her hair that it's in Ireland.
- Ill Girl: For brief intervals in "Primeval" and "The Land of the Dead".
- Innocent Fanservice Girl: Very reluctantly so in "Primeval". The Doctor eventually caves in and lends her his coat to cover up with.
- Killer Rabbit: "Spare Parts" reveals that the Cybermats originated as toys/pets for children on Mondas, since animals couldn't survive in the cavern environment. Nyssa mistakenly brings one home to the TARDIS, causing it to leech off the ship's engines. When Five finds out, his meltdown makes the Sixth Doctor look positively staid by comparison.
- Letting Her Hair Down: In "Circular Time", she briefly tries a simple human life, even wearing jeans for a while. The Doctor gently encourages her to explore it.
- A Little Something We Call "Rock and Roll": In "Primeval"'s, Nyssa teaches a bemused Trakenite how to dance the Charleston to the accompaniment of Atari music (It's the best their computers can manage, as there're no music recordings on Trakken). She invites the Doctor to dance as well, but he politely begs off."The mark of a true gentleman is to know how to Charleston and not do it."
- Poison-and-Cure Gambit: Shortly after leaving home in "Keeper of Traken", she unknowingly became a puppet for Kwundaar, one of the Old Ones who ran the universe back in the bad old days. When Nyssa falls ill, the Doctor thinks it's because she has no built-in immunities (since Trakenites have long since eliminated disease), when it's actually a ploy to lure them there.
- Poke in the Third Eye: Nyssa's powerful brain is a doubled-edged sword. Like the Doctor, she shrugs off most psychic influence, but she's actually more vulnerable to negative auras than humans are.
- Real Life Writes the Plot: Due to Sarah Sutton being the only Fifth Doctor companion (apart from Nicola Bryant) being readily available to Big Finish for a long timenote — as well as Author Appeal from Peter Davison, a longtime Nyssa fanboy — Nyssa's character was expanded as a matter of utility.
- Sacred First Kiss: She has her first kiss with an English bloke in Stockbridge. The moment shocks her — all her life, she'd imagined it as a logical thing, something that might happen and that she would have to deal with as part of a larger process, but the moment comes and goes very quickly and naturally. She gives the relationship a go, but soon realises that she has a lot to learn and she hasn't found the right person yet.
- Science Hero: Can keep up with the Doctor, and does much autonomous research while he's busy with other plotlines. He even trusts her to repair the TARDIS all by herself at times.
- The Spock: She does show a flicker of dry wit whenever the Doctor's plans go tits up on him again. Earth humor goes completely over her head.Nyssa: I am not a princess.
Korky: Aye, but yer close 'nough that you couldn't tell that was a joke.
- Sweet Polly Oliver: She spends the last act of "Primeval" in the Doctor's cricketer coat, and not much else.
- Tastes Like Diabetes: Conversed about in "Circular Time" Nyssa takes advantage of her and the Doctor's downtime to write a memoir (framed as a fantasy book) about her home before it was destroyed. Playfully, Andrew needles her about the tedious blissfulness of Traken and lack of any meaningful antagonist. Nyssa confesses that, once the true villain enters her story, the book will end—and she will no longer be able to entertain the fantasy that her world exists somewhere.
- Technical Pacifist: In "Spare Parts", Nyssa becomes trapped in the TARDIS as it's being swarmed by Cybermats. Finally, she has enough and electrifies the outer hull, which she describes as "worryingly satisfying."
- You Can't Go Home Again: Well, the Doctor does take her back to Traken... a few thousand years into her past, before her people exchanged fanaticism for science. The Trakenites are as litigious as ever, though, severely testing the Doctor's temper as he's forced to jump through bureaucratic hoops to prove they're not heretics.
Tegan Jovanka (Fifth Doctor)
Voiced by: Janet FieldingJanet Fielding agreed to do one, and exactly one, audio for Big Finish, set after her travels with the Doctor. However, she came onboard full time in 2010, Tegan now rather regularly travels with the Fifth Doctor and his other companions in tales taking place during their time on the show together, both in the monthlies and in the Lost Stories.
- Contrived Coincidence: A Harsher in Hindsight example. "The Gathering" features Tegan showing up again, for what Janet Fielding said would be here only episode (at the time) taking place after she had decided to leave the TARDIS (much longer from her perspective than the Doctor's, though). The Fifth Doctor offered to take her traveling again, but Tegan declined. Because she was suffering from apparently terminal cancer. Later, in September of 2012, Janet Fielding revealed that she's currently fighting cancer.
- Deadpan Snarker: Actually amplified in some episodes compared to the old days in The '80s.
- Demonic Possession: Since Tegan's back, so is the Mara. Well. Sorta.
- Emergency Impersonation: In "The Lady of Mercia", she manages to pose as a 10th century warrior queen by virtue of being scary and loud.
- Open Mouth, Insert Foot: Much like in the old days, and in those tales taking place during her TARDIS travels, Tegan's mouth still gets her into trouble.
- Sarcastic Devotee
- The Knights Who Say "Squee!": When meeting Harry Houdini.
- Taking the Veil: An amateur-built time machine simultaneously sends Tegan back to 918 A.D. and replaces her with Æthelfrid of Mercia. Worryingly, the real Æthelfrid is due to fight a decisive (and doomed) battle with the Danes that same morning. At the end, the Doctor manages to safety deposit Æthelfrid at a convent, where she will vanish into the mists of history. Before he returns in the TARDIS, though, Tegan is stuck pottering around the convent for a few days.
- You Will Be Beethoven: In "The Lady of Mercia", she manages to pose as a 10th century warrior queen by virtue of being scary and loud.
Vislor Turlough (Fifth Doctor)
Voiced by: Mark StricksonTravelling with the Fifth Doctor, Turlough is typically not in the mood to deal with humans, with Earth, or with having to play the hero sometimes.
- Belated Backstory: "Kiss of Death" explains more in detail about Turlough's past, and why he never changes out of his Limited Wardrobe. 30 years after he was last on TV.
- Butt-Monkey: The majority of his adventures take place on Earth, his absolute least favourite planet in the galaxy. He keeps begging the Doctor to go for a holiday on the planet of warm beaches and cute girls. The Doctor ignores him.
- Deadpan Snarker:Fifth Doctor: Where is your sense of adventure?
Turlough: In my room in the TARDIS, in a box marked "sense of adventure".
- Enemy Without: In "Loups-Garoux", a group of werewolves hynotises him into seeing a visual manifestation of his dark side. It really scares him.
- Fish out of Water: The Doctor tries to show him all the best parts of Earth and to teach him cricket. It doesn't take.
- Girl of the Week
- Lovable Coward: His first action when faced with danger tends to be to run to the nearest place of safety or even re-enter the TARDIS, to both the amusement and annoyance of the rest of the TARDIS crew. Lampshaded every few minutes in Heroes of Sontar.
- New Old Flame: Meets up with an old girlfriend of his in "Kiss of Death". Subverted when she's actually working with the bad guys of the story, and dies in his arms when she rejects them.
- Not So Different: With a (faultily cloned) Sontaran in "Heroes of Sontar".
- Not What It Looks Like: In "The Lady of Mercia", the Doctor and Turlough bear witness to some illicit affairs going on in the Frodsam U. physics department: A lively couple is shagging their students and faculty both. A jealous preppie barges into the lab and spots the wife with Turlough, who is also wearing a school uniform. Things being what they are — and Turlough being, Turlough — it isn't long before Turlough gets socked right in the nose.
- Real Life Writes the Plot: Mark Strickson no longer lives in the UK, which meant that Turlough stories were intermittent for a long time; there were just three between 1999 and 2005, then nothing at all until 2010 bar a Companion Chronicle.
- Sour Supporter: Any time he realises he has to be heroic, it's with a weary sigh.
- You Can't Go Home Again: He's tremendously homesick at times.
Perpugilliam "Peri" Brown
Perpugilliam "Peri" Brown (Fifth and Sixth Doctors)
Voiced by: Nicola BryantUnlike on television, Peri had many adventures with the Fifth Doctor before "The Caves of Androzani". She had a few with the Sixth Doctor as well.
- Author Appeal: Her main writer is Nev Fountain, who's Nicola Bryant's boyfriend.
- Break the Cutie: "The Reaping" might as well have been called "Peri Gets Broken".
- Character Focus: "Peri And The Piscon Paradox" is two hours of Peri-centric comedy, followed by one hell of a Mood Whiplash.
- Cloning Blues: Thanks to the events of "The Trial of a Time Lord", it turns out that there are five different versions of Peri in the universe. Worse is that the number given was only the one at that moment, meaning there could be more.
- Dead Alternate Counterpart: Inverted and enforced; during the Doctor's trial, Peri's timeline was altered and she was assassinated to discredit the Doctor by corruption within the offices of Gallifrey. However, realizing that the Doctor would likely take umbrage with a friend of his being killed by his own people, a new faction decided to instead have Peri be alive and married to King Yrcanos. However, another faction considered this to be akin to a fate worse than death, and so they set up Peri with another fate... and then another, and another. The heavy manipulation of her timeline splintered it and caused each Peri's fate to be in-canon, multiplying her. Suffice to say, the Doctor isn't pleased when he learns of this.
- Future Me Scares Me /I Hate Past Me: Peri gets a great smacking of this in "Peri And The Piscon Paradox", finding that she has become a cold-hearted, alien hunting secret agent. Neither past nor future Peri get along very well. Unfortunately, "Mindwarp" certainly happened, and the self the past!Peri observed is actually a version of herself the Time Lords created, among others, to try and avoid the wrath of the Doctor post-trial. And no, she's not a secret agent nor alien hunter - she's just a television host who has had a very bad marriage with her highschool sweetheart, and had to act the part to keep the web of time stable.
- Hello, Nurse!: Even Peri is starting to tire of being desired by everyone.
- Heterosexual Life-Partners: With Erimem.
- I Need a Freaking Drink: After a while, she starts just disappearing in the middle of Six's lectures and wandering off to the nearest bar.
- Law of Inverse Fertility: She would love to get Happily Married and have children someday. In "Peri And The Piscon Paradox", it's revealed that the copy of Peri who was returned to earth became infertile due to severe Domestic Abuse.
- Identical Stranger: Nicola Bryant finally get to use her natural accent thanks to the hoary old trope of meeting her spitting image in a historical setting. It's Queen Anne in "The Church and the Crown". Someone else comments that Peri has a ridiculous accent — no comment.
- Ms. Fanservice: Preview comics for the audio episodes tend to show off her... assets. In "Nekromanteia", she gets completely naked.
- The Pirates Who Don't Do Anything: A bit of a Running Gag, as every time her skills in botany might come in handy, she gets interrupted by plot.
- Pun: She admits she's a bit addicted to making them.
- Real Women Don't Wear Dresses: She is more of a leotard and shorts kind of girl.
- Reality Ensues: The episode "The Reaping" loves this trope. Peri returns home, years later from her perspective, and four months later in her mother's normal timeline. Things go very, very wrong.
- Ship Tease: She fancies Five quite a lot. Six... not so much.
- Shouldn't We Be in School Right Now?: Discussed a few times.
- Single Woman Seeks Good Man: Poor, poor, poor Peri keeps fancying men who turn out to be villains. Or wife beaters. Or... well, you know.
- The Slow Path: In "The Kingmaker".
- Tomboy and Girly Girl: With Erimem. Peri's the girly girl, Erimem is a warrior who spends much of her Story Arc with a shaved head.
Melanie "Mel" Jane Bush
Melanie "Mel" Jane Bush (Sixth and Seventh Doctors)
Voiced by: Bonnie LangfordMel's timeline got a bit wobbly as soon as she was introduced in the TV series, which Big Finish delights in making even more complicated. Stories starring her tend to be light-hearted and fun. Since the Seventh Doctor isn't quite The Chessmaster yet during their travels together (as he would eventually become with Ace), the two of them become quite adept at the Indy Ploy.
- Beware the Nice Ones: Melanie Bush made Davros beg for mercy. She spent months believing he was a kind old crippled professor. Once it turns out Davros is a lying sack of crap and reverts to form, Melanie decides to leave him at the so-called mercy of his own creations: the Juggernauts. Who are Mechanoids enhanced with human remains. Just don't piss her off, really.
- The Bus Came Back: Temporarily ends travelling with Glitz to rejoin the Doctor, now with Ace, in a 2016 trilogy of stories.
- Ditzy Genius:Mel: But, Doctor, we know they can't change history because we've seen the future already.Seventh Doctor: No. Unfortunately there is an awkward thing called "free will".Mel: Oh. You mean that predeterminism is merely a philosophical abstract and that the physical reality of the universe is the one in which all potential actions are permitted, including those whose effect cancel out their own logical cause?Seventh Doctor: ... Yes, Mel.
- Fish out of Temporal Water: She gets very annoyed at anything that's not The '80s.
- Fun Personified: Although she can be plenty glum and snarky, she's almost always brought in when a story needs to be Lighter and Softer. To the point where two of her episodes are full-on Panto.
- And when her stories do get serious, you know something's very, very wrong.
- I Need a Freaking Drink: After a while, she starts just disappearing in the middle of Six's lectures and wandering off to the nearest bar (exactly like Peri before her).
- 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, and she only just learned what Daleks are, but still...
- Reality Warper: In the 2013 Sixth Doctor story "The Wrong Doctors", its revealed that Mel's powerful memory and contradictory timeline actually gives her, under the right conditions, the power to pick and choose among countless alternate realities and timelines, pulling them into being in a pocket universe version of Pease Pottage created by a demonic entity from the Time Vortex.
- Real Life Writes the Plot: Bonnie Langford no longer lives in the UK, and the resulting scheduling difficulties meant there were no Mel stories released for some five and a half years between 2007 and 2013.
- The Slow Path: She gets stuck in 1782 for six months.
- Straight Man: Increasingly relegated to the role of the Doctor's keeper. Six is always indignant (forcing Mel to smooth things over), and Seven never shuts up (he can't craft a halfway-decent alibi without Mel backing him up).Mel: Doctor, do you know what happened to Holmes in the end?
Mel: Watson bashed him in the head with his own violin for being so aggravating.
Dorothy "Ace" McShane
Dorothy "Ace" Gale McShane (Seventh Doctor)
Voiced by: Sophie AldredAce is just a bit older, now even more awesome, and travelling with the Seventh Doctor with no intention of ever stopping. She also appears in a few "Side Step" stories, which take place during the Doctor Who New Adventures.
- Affectionate Gesture to the Head: She eventually kisses the Doctor, once, as a very sweet gesture of friendship. Since it's audio, feel free to imagine it as a Big Damn Kiss.
- Break the Cutie: From her very first Big Finish episode onwards, she gets broken over, and over, and over.
- Can't Stay Normal: Due to events involving the Word Lord, she ends up stuck in 2027 A.D. She makes a half-hearted attempt at living a normal life, but (despite finding a wonderful fiancé) ends up working with UNIT and through sheer determination eventually finds her way back to the Doctor against all odds. As soon as she can go back to the TARDIS, she abandons her fiancé without hesitation, though she cries over the life she might have had. She does try to leave a goodbye for him, and an explanation why she's going, but the Doctor (unknowingly) erases it, and she's too drained by the initial message to make another.
- The Chessmaster: Shows off hers skills extensively in "A Death In The Family", slowly but steadily outwitting a Reality Warper. She's shocked, in the end, by how well she did, considering it's usually the Doctor who does that sort of thing.
- Determinator: In "The Shadow of the Scourge", she faces an Eldritch Abomination that talks its victims into crippling despair. Her solution? To have someone destroy her eardrums, because she knows the TARDIS medbay can just fix her up later. She spends over half the story completely deaf and with blood running out of her ears, and she's not even bothered.
- Give Him a Normal Life: The Doctor regularly rotates out his companions, and Ace is a living demonstration of why. She's unstuck in time: no relationships, losing track of how long she's been traveled in the TARDIS, more and more willing to resort to unsavory methods. If the Doctor wanted a chessmaster for a companion, he'd talk to himself.Doctor: Picking up a gun? Launching a missile? Destroying a planet?
Ace: (Coldly) You've done it.
Doctor: You're not me! You were never meant to be!
- Guile Hero: Taking a few levels in the trope, and trying to be more like the Doctor. She's not extremely good at it at first.
- Hidden Depths: Her first adventure ("The Fearmonger") shows both her extreme fear of, and her total devotion to, the Seventh Doctor.
- I Have You Now, My Pretty: David Tennant's character in "Colditz" has some very unsavory intentions towards her.
- In Love with the Mark: She immediately sets to work resurrecting the Doctor in "Death in the Family." Stranded as she is with a dying TARDIS, Ace spends several months dating a man named Henry Noone, a relationship that grows serious enough that Henry eventually pops the question. Ace ultimately abandons Henry, having taking advantage of his surname to compete with Nobody No-One. But it’s clear that there was genuine affection for him, which greatly pleases Nobody No-One.Nobody No-One: Better keep an eye on your monkeys, Mister Organ Grinder. They're learning to play music without you.
- Long-Lost Relative: Her brother Liam.
- Nice Job Breaking It, Hero!: While studying at Time Lord Academy, she goes rogue and tries to destroy Skaro far into its past. And fails, miserably.
- The Nicknamer: "Oldman Whitehair, Beatles Haircut, Frilly Shirt, Longscarf Bigeyes, Cricket Boy, Joseph And His Amazing Technicolor Dreamcoat, and Lord Byron..."
- Ship Tease: Quite a bit of it with Hex, though she mostly just sees him as a little brother.
- Story Arc: Almost uniquely for a returning TV series companion, she gets a distinct story arc in the monthlies. The early episodes tend to also be understandable as standalone stories, though.
- The Last Straw: Suffice it to say, the Doctor Ace travels with has left her with a number of grievances, particularly in how he continues to manipulate allies as though they were part of a game even when it's brought up how distrustful it makes said allies and makes them have a bad tendency of messing up otherwise sound plans they aren't aware of. This has made her threaten to leave he TARDIS a number of times, but they never held until the Doctor deliberately allows Jan to die in the adaptation of "Love and War". Sick of the constant manipulations, and having lost yet another person she cared deeply over in the name of a plan to fight the monsters, Ace leaves the TARDIS.
- Took a Level in Badass: The Doctor manages to enroll her in Time Lord Academy (after at least one failed attempt), and she becomes a Celestial Intervention Agency operative. This was originally planned for the TV series.
- In a more understated one, Ace learning how to pilot the TARDIS without training, cumulating in her actually being able to roughly pilot it in "Afterlife". "Signs and Wonders" showcases a much better departure.
Donna Noble (Tenth Doctor)
Voiced by: Catherine TateDonna returns in a series of adventures with the Tenth Doctor
- Be Careful What You Wish For: In "Death and the Queen", Donna meets a good-looking guy, a prince no less, who's legitimately interested in her and doesn't just want to use her as a snack for hungry spiders, and gets the chance to be a queen. But while her prince does genuinely love her, he also plans to sacrifice her to prevent his country being destroyed.
- Blatant Lies: She tells the Doctor about all the perks of being royalty. These are immediately shown to be lies, showing Donna moaning about every little part of being pre-Industrial Revolution royalty (handmaids following her every movement, no indoor plumbing, having to wait for her boyfriend to come home with dinner, a mind-bogglingly obnoxious mother in-law).
- Buffy Speak: She calls a roulette wheel a "spinny thing".
- Royals Who Actually Do Something: When "Death" starts attacking Goritania, Donna tries rallying the people, and has them sequester themselves inside the castle for safety.
- Running Gag: Once more, the Doctor and Donna are mistaken for lovers, this time by the Queen of Goritania thinking the Doctor's come to steal her back.
Captain Jack Harkness
Captain Jack Harkness (Ninth and Tenth Doctors)
Voiced By: John BarrowmanJack's back with a new Torchwood team.
Professor River Song (Sixth, Seventh, Eighth, Tenth, Eleventh and Twelfth Doctors)
Voiced By: Alex KingstonRiver pays the Doctor the visit, but finds that he's younger than she remembers.
- Berserk Button: Though River describes herself as a psychopath, she takes it upon herself to help innocent people when they get caught up in nasty occurences they don't deserve (chalk that up to the Doctor). This puts her at odds with the Rulers immediately. She then shows just how much of a psychopath she can be.
- Reading her diary is another, as is impersonating the Doctor with it. Even when keeping the man who did the reading and impersonating alive would be optimal, she shoots him dead after freeing herself out of spite.
- Involving the Doctor, particularly against her, is yet another. She is particularly unhappy when she finds out the incarnation of the Doctor who receives the Rulers' party invitation is Eight. She views Eight as naive, and finding out this version from him is from the early days of the Time War makes her all the more incensed.
- The Bus Came Back: After her final appearance in "The Name of the Doctor".
- Call-Forward: River has her sonic trowel in "The Diary of River Song", before it was established on-screen in "The Husbands of River Song".
- Everyone Has Standards: Though River plays hard and fast with time travel, she doesn't approve of the Rulers Of The Universe's plans to live up to their name at all and sabotages their schemes twice over. The second time includes quite a lot more explosions than the first time, and quite a few more people dying. She does sound an alert so that the people partying can get to life-rafts, and she doesn't stop anyone from escaping, but if they're too busy partying or trying to manipulate planets to evacuate she sees that as their problem. Of course, she doesn't take kindly to those who escape by trampling others to do so...
- She also has respect towards the Doctor's timeline in that there are certain Doctors she cannot "play with", one in particular being the Eighth. That doesn't stop her from helping him in any way she can while he's stuck in a death trap she inadvertently brings upon him.
- Have We Met Yet?: Par for the course for River. However, unusually for her, she takes great pains to ensure that she and the Eighth Doctor do not meet, knowing this incarnation hasn't and thus cannot meet her. note
- She later encountered the Sixth and Seventh Doctors, who then forget her after an adventure in a collapsing time anomaly wipes River's and Seven's memories and elects to use her amnesia lipstick on the Sixth after he accidentally commits an immoral act and gets concerned he might get too affected by it.
- Loophole Abuse: Think that setting your base in a field that prevents time travel will save you? Not when the depot that supplies you isn't covered by a similar field. River exploits it for all it is worth, and and then some.
- Timey-Wimey Ball: River is very adept with her vortex manipulator. After the twelfth time she re-arrived at the party, each time dressed up as a service robot and planting anti-matter bombs about, and departed on one of the escaping life-rafts, she simply stopped counting. She simply sums it up the times she went back with "enough".
- Tranquil Fury: River can pleasantly discuss how she managed to completely destroy a massive space station with temporal manipulation equipment, complete with a disguise she took over a dozen times at the same time and yet make it exactly clear just how enraged she was to do it.
- Unexpected Character: She's the first companion from the new series to return to Big Finish and interact with a younger Doctor.
- Woman Scorned: The Rulers of the Universe made a very keen mistake when they tried to recruit River Song, unintentionally and continuously hitting every one of her buttons. Handing her over to a man who impersonates a future incarnation of the Doctor, clones her and kills off said clones after they realize who he is, with her being aware of everything said clones went through, is what really sends her over the edge though. Bertie Potts is horrified when he sees the destruction River brings upon them, alone and in less than an hour, and even more so when he learns how. In short? Do not piss off River Song.
Big Finish has introduced many new companions, who travel with the Doctor and sometimes afterwards have adventures without him .

Dr. Evelyn Smythe
Dr. Evelyn Smythe, later Evelyn Rossiter (Sixth and Seventh Doctors)
Voiced by: Maggie Stables (2000–2011)One of the Doctor's rare older companions, 55-year-old history professor Evelyn Smythe could also match the Sixth Doctor's acid tongue — a rare bird indeed. Evelyn is by far one of the warmest, friendliest and most emotionally involved companions that the Doctor has ever had. On the one hand, this mellows him out considerably, and the two of them become incredibly close. On the other hand, though, Evelyn can't even begin to cope with the amount of pain and death that a TARDIS traveller sees, and although she tries to stay brave, every friend she loses breaks her heart.
"I'm a historian. This is a time machine. You can take me anywhere... and I'll still be home in time for tea."
- Anachronic Order: From "Thicker Than Water" onwards, her episodes get released out of order.
- Anguished Declaration of Love: A platonic one to the Doctor.
- Badass Teacher: She's a history teacher. And she's badass. She also knits sweaters for her students.
- Break the Cutie: She tries to stay brave throughout her adventures, but the cracks begin to form at the end of "Jubilee". She starts to properly break in the middle of "Doctor Who And The Pirates". "Project: Lazarus" sees her finally unable to cope with the Doctor's lifestyle.
- Christmas Cake: One of the oldest companions the Doctor has ever had.
- Continuity Snarl/Alternate Continuity: Her appearance in the Past Doctor Adventures novel "Instruments of Darkness" features Evelyn leaving the TARDIS in a completely different manner to her eventual finale years later in "Thicker Than Water", mostly due to Big Finish's changing attitudes to cross-medium continuity. And the cliffhanger ending to "Real Time", where the Cyber-controller was actually a future Evelyn was left unresolved due to the BBC abandoning the webcast format.
- Cool Old Lady: Cool enough to chill out Six. (A little.)
- Cybernetics Will Eat Your Soul: In "Real Time".
- Deadpan Snarker: She is naturally quite straightforward, but the Doctor's more boastful rants tend to bring out this side of her.
- Foreshadowing: Thanks to Big Finish releasing episodes in whatever Anachronic Order they like, the Doctor often fondly remembers Evelyn in episodes taking place after she leaves team TARDIS... which are released long before we know why she leaves team TARDIS.
- Genius Sweet Tooth
- Happily Married: To Rossiter.
- Hard-Drinking Party Girl: Evelyn regularly parties with her students, and recalls taking part in a yard of ale drinking contest with them.The Doctor: "Who won?"Evelyn: "Oh the yard of ale, definitely."
- The Heart: A serious contender for the warmest, kindest, most emotionally involved companion the Doctor's ever had. She slowly learns that those qualities are not at all suitable for the amount of death and pain a TARDIS traveller tends to see.
- Heroic Sacrifice: Helping the Doctor take out a being of nearly ultimate power, at the cost of her own life... as she was already dying, Evelyn was more than willing to ensure her end happened on her terms.
- I Choose to Stay: With Rossiter.
- It Gets Easier / It Never Gets Any Easier: Evelyn's main arc revolves around her coping with all the death that follows in the Doctor's wake. He seems to take it all in his stride, while she, well, doesn't. What she takes away from it is that there is no happily ever after, because life has no ever after, just days that are happy and days that are sad. And as long as one person cares, you can keep on living until the next day.
- It Is Pronounced "Tro-PAY": Eve-eh-lyn. At one point she posses as Evil Evelyn, the Pirate Queen.
- Jumped at the Call: Six doesn't get any say in whether or not she gets to be a companion, since she's already made up her mind just minutes after they first meet (well, after he proved he wasn't a lunatic anyways). As we find out much later, it's partly because she suffered a heart attack not too long before, and the university wanted to try and force her into retirement.
- Married to the Job: Almost literally, in that she divorced her husband so she could spend more time at work.
- Medical Horror: Especially in "Real Time" and "Thicker Than Water".
- Morality Chain: She really brings out Six's softer side, and he grows to care tremendously for her. She also calls him out hard when he puts on a brave face and pretends that everything's fine when it very clearly isn't.
- Non-Action Snarker
- Not That Kind of Doctor: She often has the same problem as the Doctor when describing herself.
- Older Sidekick: She seems noticeably older than the 40ish Sixth Doctor, though she technically isn't.
- Parental Substitute: Eventually becomes one for Hex.
- Screw Politeness, I'm a Senior!: Usually, Evelyn's a perfectly friendly old dear, but when she needs to get her way...
- Scout Out: In "The 100 Days of the Doctor", Evelyn, bewildered by the implications of regeneration, asks if the Doctor loses all of his accumulated life lessons. Six searches for a positive spin to put on this; he suggests that one keeps the memories, but views them from an outsider's perspective. This reminds Evelyn of another one of life's great hurdles:Doctor: The ultimate mystery of the Time Lords... is like signing on with the Girl's Junior Scout Troop. That's... one of the most spectacular similes I have ever heard attempted.
- Thanatos Gambit: A future Evelyn, now on her deathbed, manages to trick the Word Lord into becoming trapped in her mind as it slowly shuts down.
- Your Days Are Numbered: She's hiding a serious heart condition from Six, and part of the reason she wants to travel in the TARDIS is to live life to the fullest while she still can.
Princess Erimemushinteperem (Fifth Doctor)
Voiced by: Caroline Morris (2001–2008)Erimem is a daughter of Pharaoh Amenhotep II. Rescued by the Fifth Doctor and Peri from Ancient Egypt 1400 B.C. after a few complications involving her impending coronation, she travelled the galaxy with the Doctor to learn about different times and places. Also appears in a number of prose stories and novellas and the solo full-length novel The Coming of the Queen, and subsequently in her own book series by Thebes Publishing.
"I believe in real things. I have heard of men who study the stars."
- Abusive Parents: Comes with the time period, but it's revealed in "The Roof of the World" that her father planned to have her tossed to the lepers for accidentally seeing something she wasn't supposed to. And she only finds out about this in limbo. But as it turns out, it was all to protect her and the rest of the world.
- Action Girl: She was trained in sword(wo)manship by the Captain of the Royal Guard. Comes in handy when they visit Three Musketeer-era France.
- Ambadassador: She's extremely adept at political negotiations... but not mature enough to judge when to stand up for her convictions and when to simply keep silent. When push comes to shove, she can also fight her way out.
- Ancient Egypt
- Attempted Rape: In "Nekromanteia", in an attempt to make the series a bit Darker and Edgier, Erimem is almost raped but manages to fight off her attacker. (Fan reception of the episode was overwhelmingly negative, and the author was never hired to write for Big Finish Doctor Who again.)
- Badass Normal: Erimem never just sits back when there's trouble.
- Bald of Awesome: She shaves her head at the start of "The Church And The Crown" just because she feels like it, and keeps her hair that way for a while.
- Beware the Nice Ones: Has a habit of casually breaking people's arms when they try to touch her in less pleasant ways.
- Bi the Way: Revealed to be bisexual via Word of Gay in her book series.
- Blue Blood: Being born under the king of Egypt will do that to you, though she doesn't flaunt it.
- Break the Cutie: She definitely has her moments. Nearly being raped in "Nekromanteia" for one, being convinced she was dead in "The Roof of the World", and seriously considering suicide in "The Kingmaker". She powers through, regardless, if a bit weathered.
- Deliberate Values Dissonance: She sees nothing wrong with corporal punishment and a moderate level of fascism, if it's for the good of the people. This becomes very interesting when she gets into a sort of romance with Vlad III, Prince of Wallachia... a.k.a. Dracula.
- Driven to Suicide: In "The Kingmaker", although seeing Peri's reaction to the idea stops her. She pretends it was all just a joke, but later reveals to the Doctor that she was deadly serious, and that she feels tremendously guilty for lying about it to Peri.
- Everything's Better with Princesses: Well, Pharaoh really. She doesn't enjoy the title, and it loses all political power once she leaves Egypt, but she does retain quite a number of skills from growing up in royalty she makes good use of.
- Guile Hero: Years of court etiquette gives her a lot of skill in manipulating people. She effortlessly talks her way into the King of France's court, and manages to stay in Count Vlad's good graces despite the very hostile environment.
- Fake Nationality: Erimem's Egyptian. Her actress is most certainly not.
- Faking the Dead
- Fish out of Temporal Water: Frequently. "The Veiled Leopard" has her in a bodice and high heels, wanting to try 1960's French fashion. She immediately regrets that decision when she realises she can't properly move anymore.
- Friendship Moment: In "No Place Like Home", she and the Doctor quickly bond over how dreadfully stuffy and ceremonial their respective civilisations are. She also learns that he's technically the President of Gallifrey, and that he's on the run from it, just like she is. She and Peri have many besides.
- Heterosexual Life-Partners: Mainly with Peri. They're the equivalent of gossiping girls when around each other.
- Incest Is Relative: Was engaged to her brother before his untimely death, and rather excited about the prospect.
- Rebellious Princess: A textbook example.
- Royals Who Actually Do Something: She sees no reason to not go into battle with her troops, and is quite able to rally an army should she need one.
- The Slow Path: In "The Kingmaker".
- Team Pet: Antranak, a stray cat she dragged along during her hasty escape from ancient Egypt. The Doctor really doesn't get along with Antranak, but tolerates the cat for Erimem's sake.
- Translator Microbes: An odd aversion to the trope; though the TARDIS allowed Erimem to converse with people who didn't know Egyptian just fine, she had to be taught by Peri over the course of several adventures how to read and write English. Before that, she only knew (and could read) Egyptian hieroglyphs. It's never elaborated on whether or not this was a problem with the translator circuit that was later fixed.
- Tomboy and Girly Girl: With Peri. Peri's the girly girl, Erimem is a warrior who spends much of her Story Arc with a shaved head.
- The World Is Just Awesome: When she first joins up with the Fifth Doctor, she's never ever heard of tea. The Doctor promises to take her out for snowball fights and ice cream and anything else she's never seen before. Her travels leave her in a perpetual state of wonder, though due to her excellent etiquette, she's never too much of a Fish out of Water.
Charlotte "Charley" Elspeth Pollard (Eighth Doctor and Sixth Doctor)
Voiced by: India Fisher (2001–2010, 2013–present)
Charley: Did they have orgies?
Eighth Doctor: CHARLOTTE POLLARD!!!
Charley: I went to an orgy once... I didn't stay.Edwardian adventuress Charlotte Pollard ran away from her boring life among the upper crust in 1930, only to be nearly killed in an airship crash. Fortunately, the Eighth Doctor was around. Charley is a pragmatic and very adventurous young lady who strongly values Brutal Honesty, making up for her lack of life experience with a willingness to try anything once. Got her own spin-off.
- Alice Allusion: In "Zagreus", she's forced to take on the role of Alice, take up the Vorpal sword, and fight the Jabberwock. It turns out that the TARDIS was trying to save reality itself by confusing Zagreus into submission, using the most nonsensical thing she could possibly find in Charley's head: her memories of reading Alice in Wonderland.
- Anguished Declaration of Love: She and the Doctor exchange one, though they both mean different things by it, in "Neverland". Things get extremely out of hand after that in "Scherzo".
- Be Careful What You Wish For: She very much wants to become a mother. The idea is explored in a variety of creative ways, none of which are at all fun for Charley.
- Big Damn Kiss: With the Doctor in "Scherzo". It's played for terrifying, indescribably gruesome Body Horror.
- Brainwashed and Crazy: Seemingly falls victim to it every second story, may actually have toppled Sarah Jane and Leela as the most brainwashed companion.
- Breakout Character: One of the most popular Doctor Who companions ever, lasting four entire story arcs: her initial run with Eight, the Divergent Universe arc, her second arc with Eight, and her run with Six. After which she promptly got her own spinoff. Also the only original Big Finish character to come back for the Big Finish 50th anniversary, and the first Big Finish companion to be mentioned by the Eighth Doctor in his return to the screen. She's the first Big Finish character to appear in Doctor Who Legacy, too. Word of Moffat has it that she was also with Eight during the climax of "The Day of the Doctor", standing just offscreen.
- Brutal Honesty: Like her description above says, she's a big fan of it.
- Buffy Speak:A 'thingamy' was a tool, one hit someone else with a 'dooda', and a 'whatsit' bleeped. One could always combine them, of course. 'Thingamydooda' would suit a space spanner, for example. Once, for variety, she had tried out 'oojamaflip', but she’d found it rather common.
- Canon Immigrant: Mentioned in "The Night of the Doctor".
- Catch-Phrase: "My friends call me Charley". Quite a bit of drama is gotten from characters adamantly calling her "Charlotte" regardless, especially the Sixth Doctor.
- Characters as Device: Enjoys lampshading her Sidekick status:C'rizz: Doctor, what's happening?
Eighth Doctor: Hmm?
C'rizz: I said "what's happening?"
Charley: No, not like that. Ahem. "Doctor, what's happening, Doctor?!!"
C'rizz: Oh, that's good.
Charley: Practice, you see.
- Double Consciousness: Develops one after "The Chimes of Midnight", and remembers both dying in the R101 and being rescued by the Doctor.
- English Rose: She was raised to become one, but said Screw This, I'm Outta Here! as soon as she had the chance to. However, many of her traits fit perfectly the idea of a pretty, classy English girl. She has hard time dealing with the fact she's not going to see her family ever again and she longs to become a mother. She speaks in the classic received pronunciation, she likes Jane Austen and history, and her etiquette lessons come quite handy during her time-travelling adventures. Occasionally referenced:Keep: There's a tint to your skin.
Charley: [sarcastically] It's called English Rose.
- Gorgeous Period Dress: A huge fan of it. Jane Austen is one of her favourite authors, and she's very much in love with the past. She also sees historical adventures as an excuse to put her endless etiquette lessons to good use, which typically makes the Doctor groan.
- Ignored Enamored Underling: The Doctor knows full well that Charley's madly in love with him. He ignores it until it's much, much too late, at which point they're stuck in the living hell of "Scherzo". Much later, Charley tells the Sixth Doctor that Eight had been in love with her, too — although he'd never have admitted to being in love, per se.
- Lady of Adventure: Will try anything once, and very quickly and eagerly adapts to future culture and technology. Loves wielding giant swords, even if she has zero skill with them. Ran away from home to dress up as a boy, sneaked into an international experimental zeppelin flight, and got to Singapore on time for a romantic rooftop rendezvous.
- Law of Inverse Fertility: Played With. She really, really wants to become a mother, but the universe seems to conspire against her in that regard... making her give birth to monsters over and over.
- MacGyvering: Comes up occasionally. Her excellent upper-class education gives her a few levels in Science Hero, which she uses whenever it's necessary. In "Solitaire", she's able to fashion a rudimentary electromagnet out of its base components.
- Mercy Kill: In one truly heartbreaking scene in "Zagreus", she puts the Doctor out of his misery after he begs her to run him through with her sword.
- Reality Ensues: Several episodes have her dealing with the realization that she will never see her family again due to them thinking she's dead. She does, eventually, in "The Fall of the House of Pollard"; though her father is happy to see her, her mother gives her a well played What the Hell, Hero? moment and Charley takes a moment to remunerate on the fallout her "death" left behind. It goes From Bad to Worse.
- Rebellious Spirit: As a child, she let Roma sleep in her family's attic. She only got more rebellious as she got older.
- Ripple Effect-Proof Memory: Develops this kind of memory after a while.
- Screw This, I'm Outta Here!: When the Eighth Doctor is relieved about C'rizz' death, Charley realises that life with him is too alien and horrifying for her.
- Ship Sinking: After the Divergent Universe arc, the Doctor makes her promise to stop yearning for him.
- Smitten Teenage Girl: Falls madly in love with the Eighth Doctor, which is completely Played for Drama. Eight is extremely uncomfortable with it.
- Sophisticated as Hell: Charley narrowly avoids a Precision F-Strike when the Celestial Toymaker forces her to think of a four-letter password - to be fair, she was in the middle of a shrinking death trap.Celestial Toymaker: Do you know how many four-letter words there are in the English language, miss Pollard?Charley: I can think of a few right now.
- Temporal Paradox: Was saved from the crash of the R101 by the Doctor, and went on to travel with him. Time appears to proceed normally, until we find out that the Doctor saving her from certain firey doom caused a ripple in the Web of Time. History wrote that Charley was supposed to go down with the ship, but because of her survival, the ripple lead to all sorts of paradoxes and tons of "things-that-shouldn't-have-happened" to happen throughout the whole of history. All this, plus causing the Web of Time to slowly unravel itself due to her merely existing.
- Time Crash: Is a living one, thanks to something going mighty wrong when the Doctor rescued her. Nearly every story in her initial arc involves time itself warping around her and history developing continuity errors. Although there's nothing particularly special about her or her rescue, she accidentally becomes the "patient zero" of a grand scale disaster. The Doctor fixes this in a rather creative way.
- Timey-Wimey Ball: Thanks to the fun of time travel in Doctor Who, Charley is one of the very few companions to know the Doctor before he knows her. Sorta. Long story short, she was a companion of the Eighth Doctor, assumed he died in an adventure and wound up later being a companion to the Sixth Doctor. Whose memory of Charley was wiped so the timeline would be preserved when he was the Eighth Doctor. Wibbly wobbly, timey wimey indeed.
- Tomboyish Name: Her Christian name is Charlotte, but she goes by Charley.
- Torture Porn: With some frequency, and most notably in "The Creed of the Kromon".
- Uncanny Family Resemblance: Her sister Cecilia, who appears in Gallifrey, is also played by India Fisher. India's likeness is used for Cecilia on the cover art, although made to look slightly different from Charley.
- Unwitting Instigator of Doom: Charley's family did not take her passing well. Years after her death, her family are nearly completely broke, having to sell their previous estate and unable to hold onto more than a single servant. At least part of their ruin was from hiring various mediums to try and contact her spirit, while another significant part was just sheer depression over her being gone. She helps them out of it, but not without cost...
- You Are Worth Hell: Charley simply will never abandon the Doctor, no matter how many times he tries to make a Heroic Sacrifice so she can live a normal life. He's very seriously not happy with it.
- You Can't Go Home Again: She realized that that she cannot and will not see her family because they naturally assume she's dead. This becomes worse come "The Fall of the House of Pollard"; Charley does get home, and faces some of the fallout with her parents. Then the Viryans catch up with her, and they erase every memory they have of her, ensuring she can never go back to them.
Thomas Hector "Hex" Schofield (Seventh Doctor)
Voiced by: Philip Olivier (2004–2012, 2014)Hex was introduced as a character well before his first proper appearance, during the Sixth Doctor's encounters with the Forge. He later became a staff nurse and was encountered by the Seventh Doctor and Ace in 2021. Hex is compassionate and good at keeping a cool head, even during his Oh My God freakouts.
"OH MY GOD!"
- Babies Ever After: Has a couple of children with Sally Morgan, after the two of them finish traveling in the TARDIS.
- Badass Normal: Considering the fact that he's just a nurse and is more than often in over his head, Hex does some pretty awesome stuff. Especially taking out two elder Gods in one day, admittedly at the cost of his own life. Not bad for someone without Nitro-9.
- Big "OMG!": Not always big, but a bit of a Catch-Phrase. Used to dramatic effect in "The Settling" with Oliver Cromwell.
- Break the Cutie: Villains love to torture poor Hex. Especially Nimrod, telling him enough of the truth about how his mother died to make him distrust the Doctor and then tricking him into resurrecting her as a mindless vampire monster. This would have been bad enough had he not just recovered from being shot. He's also been gratuitously tortured in an English Military Hospital, and nearly burned as a witch by Oliver Cromwell. Indeed, the writers at Big Finish would often joke about what crap they could shove on Hex with each new script.
- Despair Event Horizon: When he thinks the Doctor and Ace are dead and he's stranded in the Siege of Wexford, he leads the townspeople into battle and becomes a little bit of a Blood Knight.
- Did Not Get the Girl: He falls in love with Ace pretty early on. She's not interested (not to mention incapable of having a functional romantic relationship with anyone), and he gets over it eventually when he realises she'd "have [him] for breakfast". They just become close friends instead. Notably not the case when it came to Sally Morgan.
- Eye Gouge: He manages to get himself permanently blinded — turns out looking directly at a nuclear explosion is a very bad idea. Luckily for him, it was part of a "Groundhog Day" Loop, and he gets his eyesight back once the loop resets.
- Earn Your Happy Ending: Dear Lord did he. After having been literally turned into a new man by Koloon, who himself didn't exactly lead a happy life, Hex is effectively ressurected from the dead for good, and gets together with Sally Morgan. They hook up and have a couple of kids, satisfied with their lives together.
- The Heart: He's sensitive, caring, honest, and instantly falls into the role of The Chick once the team gets larger.
- Heroic B.S.O.D.:
- After the events of "The Settling", which Ace considers his very own "Ghost Light".
- After finding out the fate of his mother, not to mention the fact that the Doctor had chosen to lie by omission about her fate for so long.
- Heroic Sacrifice: A twofold one for Hex, actually. Hex uses the ultimate power of the universe in a game of proverbial chess with Fenric (yes, THAT Fenric) to take out Fenric's opponent, who wanted to destroy the universe. With the game over, and Fenric still having lost despite his opponent being banished, Fenric takes over Hex out of spite. Hex restrains Fenric (an elder freaking god, mind you) and throws himself out into the Space-Time Vortex to make sure Fenric is dealt with once and for all. While bleeding out from a fatal wound he'd received months ago that Fenric's opponent was holding back so he could use Hex as a pawn against Fenric in the first place. Holy crap.
- Hospital Hottie: Actor Philip Olivier is a professional (nude) model.
- Its Pronounced Tro Pay: Skoe-field.
- Nice Job Breaking It, Hero!: In "The Settling", he accidentally causes the Siege of Wexford.
- Parental Substitute: He's eventually adopted by Evelyn. Who then promptly dies.
- Raised by Grandparents: Hex never knew his mom, raised by his grandmother instead - he even thought she was his mom until he was older.
- The Reveal: In the middle of the Sixth Doctor story "Thicker Than Water", the Seventh Doctor shows up completely out of nowhere, uncredited and unannounced, to reveal to Evelyn that Hex is Tommie, Cassie's son from the Forge Story Arc.
- Ship Tease:
- Plenty of it with Ace. He fancies her quite a bit and would love to have a nice shag or maybe a date, but Ace just sees him as a little brother.
- He gets a few moments of these with Sally Morgan in the few times they're together. It takes.
- Taking You with Me
- These Hands Have Killed: He does not cope well with being made to fight in a war.
- The World Is Just Awesome: Hex is a bit of a sci-fi dork — and in many ways a precursor to Rory Williams — and isn't sure at first whether he's cut out for the reality of space/time adventures. He quickly warms up to it and delights in seeing new things, and Ace (who's much more jaded) loves to watch him enjoy his adventures.
C'rizz (Eighth Doctor)
Voiced by: Conrad Westmaas (2004–07)Pronounced KER-izz. C'rizz is a chameleonic monk from the Divergent universe who got kidnapped during his wedding, used as a guinea pig, and subsequently broken over and over and over again by everything that crosses his path. He tries to put on a brave face and becomes close friends with Charley. C'rizz never gets much Character Development during his first Story Arc, and as we find out eventually, there's a very good reason for that...
"The dead don't sleep."
- Artificial Human: Well, Eutermesan. And he has no idea.
- The Assimilator: As revealed in "Something Inside", he can permanently absorb people's powers by murdering them. He also takes on little bits of the personality of every person he meets, a fact he actively hates.
- The Atoner: For killing L'da.
- Anti-Hero: Most of the Doctor's companions share at least the basics of their moral code with that of the Doctor. C'rizz... really, really doesn't.
- Beware the Nice Ones: C'rizz is kind, helpful, even valiant at times, and will ruthlessly murder you or grant you a Fate Worse Than Death if you hurt him.
- Blessed with Suck: He strongly dislikes his own powers.
- Blue and Orange Morality: The way C'rizz sees the world is very alien and intensely frightening at times.
- Break the Cutie: Something the Expanded Universe excels at, it seems.
- Broken Masquerade: He keeps up the façade for a good long time. Until he can't anymore.
- Canon Immigrant: Mentioned in "The Night of the Doctor".
- Characters as Device: C'rizz is an experiment in what happens when a companion just doesn't fit in team TARDIS all that well. After his final episode, the Doctor is actually relieved that things can go back to normal again. His response horrifies Charley so much that she breaks off their friendship and leaves Eight forever.
- Creepy Good: "Good" being a very relative term, thanks to his Blue and Orange Morality.
- The Empath: Adapts to whomever he's around. The reason he has no Character Development to speak of at first is because he simply doesn't have much of an identity of his own. Entirely Played for Drama.
- Heroic Sacrifice
- Humiliation Conga: In "Other Lives", he decides to leave the TARDIS and go look for the Doctor... on 19th century Earth. He's pretty much immediately captured, chained up, forced to rip off his clothes and put on a thong, and displayed as a sideshow freak.
- I See Dead People: Originally played straight at the start of "The Last", where C'rizz is but one of a few who see the spirits of the dead surrounding them. Later actually twisted somewhat at the end of "Terror Firma", where it's revealed that C'rizz sees each and every person he's killed, or rather "saved", as a ghost around him.
- Lizard Folk: With an exoskeleton.
- Mercy Kill: Originally played painfully straight in his first story, where C'rizz is forced to kill his loved one to alleviate her suffering and release her from what is essentially an undeath. However, the repeated trauma that C'rizz undergoes eventually leads him to believe that each person that he's killed is also one that he's "saved". This includes a Dalek. His church's credo revolves almost entirely around killing, and he was one of their most adept assassins.
- Path of Inspiration: Unbeknownst to him (or to anyone, really), his church was founded by Rassilon.
- Petting Zoo People: He's a humanoid chameleon.
- Power Copying: From the people he "saves".
- Power Nullifier: He becomes quite adept at shutting his mind (and others' minds) off from scrying and hallucinations, since he picked up moderate telepathy from someone he murdered.
- Punctuation Shaker: Just like his fiancée, L'da.
- Psychopomp: What turns out to be the purpose of his existence.
- Reality Warper: In "Absolution".
- Rebel Prince: His father is the leader of the Foundation. Although it's later revealed that things are a little more complicated.
- Sealed Inside a Person-Shaped Can: The people he saves become trapped inside him forever. It's eventually revealed that this is exactly what he was created for.
- Telepathy: He picked up a bit of it once from someone he killed.
- This Looks Like a Job for Aquaman: In "Memory Lane", the heroes fight a nanotech substance that latches onto people's personalities. C'rizz is able to confuse it into a neutral state by letting it into his mind, since he has no clear-cut personality.
- Token Evil Teammate: Sort of. He's certainly this during the Divergent arc, but gradually becomes more like the Doctor and Charley, thanks to his natural ability to copy people's moods and personalities. He still occasionally maims and murders, though, and the Doctor and Charley stay completely unaware of it for a very long time.
- Torture Porn: He gets severely physically tortured in "Something Inside", and nearly dies from his internal injuries.
- Trauma Conga Line: First, his beloved is horrendously mutated before his eyes, forcing C'rizz to kill her off out of mercy. As he begins to travel to other worlds, though, it seems like each subsequent author and story was continually trying to out-do the previous one.
- Weak-Willed: His chameleonic skin isn't the only thing that adapts to his environment. As it turns out, his race also subconsciously adjusts emotionally to people around them.
- You Wouldn't Like Me When I'm Angry: He'll break your spine and rip your eyes out.
Lucie Miller (Eighth Doctor)
Voiced by: Sheridan Smith (2007–2011)Lucie bleedin' Miller is dumped on the TARDIS by the Time Lords without explanation (at first), and completely fails to be impressed by the alien ponce in front of her. Over the years, she and the Doctor end up becoming best friends.
"Just look at you. A right frock-coated ponce."
- Anguished Declaration of Love: In a welcome subversion of the trope, her big damn "I love you" to the Doctor is completely non-romantic. Apart from some very mild flirting, they really are just friends.
- Big Damn Heroes: Just when it looks like the Daleks are about to win, here comes Lucie with a spaceship and a really handy nuke.
- Book Dumb: Gets rather annoyed whenever the Doctor points this out.
- Break the Cutie: Severely.
- Brutal Honesty: Values it to the point where the Doctor lying to her causes her to break off their friendship.
- Canon Immigrant: Mentioned in "The Night of the Doctor".
- Catch-Phrase: "What's that when it's at home?", and "Hiya!"
- Combat Pragmatist
- Commuting on a Bus: She was absent for the first half of the fourth season (see Put on a Bus below). Though Sheridan Smith played two androids the Doctor had programmed to have her voice in "Prisoner of the Sun", the January 2011 episode.
- Deadpan Snarker: Extra emphasis on "snarker". Describes herself as "Sarcasmo, the Lord of Sarcasm".
- Death by Disfigurement
- Dying Moment of Awesome: Her Heroic Sacrifice literally saves the world.
- Future Me Scares Me: Subverted. It's suggested that Lucie is destined to become a ruthless dictator, but then it turns out it was someone else.
- Gratuitous French: She and the Doctor pull this at the beginning of "Scapegoat". Her French is hilariously terrible.
- Handicapped Badass: As of "Lucie Miller", she contracted a plague while on holiday with Alex, which left her blind in one eye and dependent on leg braces. In spite of this, she, Alex, and Susan staged several raids on Dalek forces. With nuclear submarines.
- He Is Not My Boyfriend: There's a running gag of people assuming the Doctor is her boyfriend, to her annoyance. Unusually for the trope, he really isn't; the two are close friends, but that's it.
- Heroic Sacrifice: Taking a doomsday nuke into the heart of a Dalek time engine while shouting out "LUCIE BLEEDIN' MILLER!" so the Daleks knew just who screwed them over. Notably, earlier on, she's a rare case of Heroic Sacrifice survivor. Once things started going to hell, she expected to die on a mission, and didn't particularly care... until she found out Susan's TARDIS key was active, and the Doctor was (finally) coming. But, lest you think Big Finish was only kidding with the title, she ends up dying anyway.
- Killed Off for Real
- The Lad-ette: Particularly in her first episode.
- Lady Swears-a-Lot: And has a lot of fun with it. Freely mixes up "bleedin' hell" with "oh, sugar!".
- Noodle Incident: More of a Jelly Incident, in her case.Lucie: ... It's just I've got a thing about jelly. Incident at a children's party, 1992. Trust me, you don't wanna know.
- Not Herself: Is very easily hypnotised and possessed, to her constant frustration. Is also extremely adept at staying conscious during mind control, though, and fighting back from the inside.
- Of Corsets Sexy: Subverted in "Scapegoat", in which Lucie, having donned Gorgeous Period Dress for what is meant to be a night at the Moulin Rouge, has this exchange with the Doctor:Doctor: You look very... uh... very... uh...
Lucie: Say "cheap" and I'll have you.
- Oop North: Lucie is from Blackpool.
- Punctuated Pounding: On several occasions. In "Orbis", the Doctor has gone amnesiac (again) and forgotten her, so she literally slaps him into remembering her, spelling her name and smacking him after every letter. It works.
- Put on a Bus: She voluntarily leaves the Doctor and returns home after an incident that makes her believe she can't trust him anymore. Her aunt Pat, whom she first met in 1974, was killed on their second visit to her and replaced by the shape-shifting alien who had been Pat's husband. The Doctor knew this and opted not to tell Lucie, against his better judgment, and she eventually found out. This broke her trust in him, until she ran into him again on a moonbase on Deimos, where she had been abandoned by the Meddling Monk, with whom she'd been traveling. She then spends Christmas with him, Susan, and Susan's son Alex, though rather than resume traveling with him she opts to explore 22nd-century Earth with Alex. He's somewhat amusingly alarmed by that, telling Alex to look after her in one breath, and warning him not to let her teach him any bad habits in the next. She eventually forgives him for the aunt Pat things... soon before she dies.
- Shell-Shocked Veteran: Spends two years living through the Dalek occupation. The Doctor is horrified when he sees her picking up a gun and threatening to shoot the Monk.
- Ship Tease: Has a few moments with the Doctor throughout season 3, and with Alex in season 4.
- Vitriolic Best Buds: With the Doctor. For all they snark at one another, they're self-admittedly each other's best friend. She does accuse him of staring at her bum a lot.
- Why Did It Have to Be Snakes?: She does not enjoy crocodiles... at all. She also has something against jelly due to an incident from her past, though she doesn't elaborate on it.
- You Put the "X" in "XY": In "The Skull of Sobek", she starts seeing strange visions. The Doctor's comment: "You put the Lucie in hallucination."
Oliver Harper (First Doctor)
Voiced by: Tom Allen (2011)A stock broker from London in the 1960s (the same time as Ian and Barbara), Oliver starts his day learning the law is after him and starts making plans to run. Then he comes across the Doctor and Steven Taylor, and gets just the opportunity he is after, while making sure that his secret isn't learned... that he's gay. Oliver stands as the first companion to be created exclusively for the Companion Chronicles, and in-universe chronologically, the first LGBT companion.
- Gayngst: He's scared out of his mind at the Doctor and Steven finding out he's gay, as in his time homosexuality was illegal and punishable by death. Of couse, neither cares — to the Doctor it's Oliver's business, and people from Steven's century haven't cared for a long, long time.
- Heroic Sacrifice: Enacts one to ensure the Doctor and Steven aren't killed by the Vardans.
- Jumped at the Call: The opportunity to travel in the TARDIS appealed with Oliver's very great desire to escape England. He gets that and more.
- Killed Off for Real: Though he does survive as a Virtual Ghost for a good time.
- Living on Borrowed Time: He believed he was on this, since he knew at some point Steven and the Doctor would learn about his sexuality. He calms down considerably when they accept him immediately.
- Sharp Dressed Man: Due to leaving with the Doctor and Steven with just the clothes on his back, Steven goes through every adventure in a stock broker suit. He even had spares at his flat to lend to Steven for a time.
- Virtual Ghost: Ends up as one due to his Heroic Sacrifice to prevent a Vardan from killing the Doctor and Steven. He ends up caught in the time trail left by the TARDIS, and stays coherent long enough to watch the Doctor regenerate in his TARDIS before properly passing on himself.
- We Hardly Knew Ye: He sadly leaves the TARDIS after only three episodes.
The Marquis Jason de Saint Epiman de Sinee de la Tour (Sixth Doctor)
Voiced by: Noel Sullivan (2008, 2011)From the Big Finish version of the stage play The Ultimate Adventure and its Companion Chronicle sequel, "Beyond The Ultimate Adventure". A teenaged French aristocrat, rescued from the French revolution by the Sixth Doctor. Jason's a cheerful and adventurous young man.
Crystal (Sixth Doctor)
Voiced by: Claire Huckle (2008, 2011)From the Big Finish version of the stage play The Ultimate Adventure and its Companion Chronicle sequel, "Beyond The Ultimate Adventure". An up-and-coming nightclub singer who accidentally joins team TARDIS.
- Canon Immigrant: Like Jason, she first appeared in the stage play.
- Career Versus Man: She picks Jason over her career, but he'd have just as easily stayed in the 1980's for her if she'd wanted him to.
- Fish out of Water
- Official Couple: She and Jason get together halfway through the play.
- Smitten Teenage Girl: To Jason.
- That Reminds Me of a Song: Terrance Dicks tried very, very hard to fit the sudden singing into an otherwise (sort of) realistic script. In the end, he just gave up and went with this trope.
- The Thing That Would Not Leave: How she joins team TARDIS to begin with.
- Tomboyish Name: She goes by "Crys".
Thomas Brewster (Fifth and Sixth Doctors)
Voiced by: John Pickard (2008–2011)A Dickensian little git who had the misfortune of getting caught up in the Doctor's life at the tender age of four. Orphaned, abandoned and raised in a workhouse, he never had a chance to get a proper education (let alone love and care from anyone), and inevitably got stuck on the path of villainy. The Doctor, feeling at least partially responsible for Brewster's ruined childhood, comes to see him as a companion eventually and tries his best to make adult Brewster's life somewhat normal again.
- Artful Dodger: After escaping from his abusive boss, he spends a few years as a teenager living the life of a Dickens-style little thief.
- Even Bad Men Love Their Mamas: Well, hypothetical future Stable Time Loop ghosts pretending to be his mama.
- Heel–Face Revolving Door: In part due to being somewhat of a Doom Magnet, and in part because being a thief is the only life he knows.
- Love Redeems: He's willing to settle down with Connie and live a normal life. Too bad she gets into a traffic accident soon after.
- Sequel Hook: Last seen ditching Earth altogether to go set up an interstellar company.
- Token Evil Teammate: Although he makes a few genuine efforts to better himself. The Doctor's companions and friends are more willing to see Brewster's good side than the Doctor himself — Evelyn genuinely wants to help the boy, and Patricia Menzies just sees him as an Ineffectual Sympathetic Villain and runs circles around him intellectually.
Alexander David "Alex" Campbell (Eighth Doctor)
Voiced by: Jake McGann (2009–2011)Susan's son and the Doctor's great-grandson. Seems to have taken the whole "Surprise! You're half-alien!" thing quite well after the initial shock, considering Earth was pretty xenophobic while he was growing up.
- Book Dumb: Alex isn't doing especially well in school. Later subverted by "Relative Dimensions", where it's revealed he wants to become an architect and is doing well in college studying architecture. It also helps that he isn't hanging around crowds who want to up-end the education system by this point in his life.
- Half-Human Hybrid: A very rare example of nonhuman Mom, human Dad. Even rarer, Alex isn't genetically half-human and half-Time Lord - the Time Lord part of him only makes up seven percent of genome. As such, he's unable to regenerate, has only one heart and is non-telepathic. The Doctor is equal parts incredulous and disappointed about it despite looking at the test results he just made in "Relative Dimensions".
- Heroic Sacrifice: Alex performed one of these, planning for the Daleks to destroy the very important console he was "trying" to sabotage when they shot him to stop him. It worked.
- It Runs in the Family: Though it takes some time to develop, Alex has quite the eye for details in his surroundings and a desire to travel.
- Tell Me About My Father: Or rather, his great-grandfather, since Alex was old enough to make several memories about his own father.
- Why Couldn't You Be Different?: The Doctor is quite disappointed to discover that Alex lacks several Time Lord traits, such as regeneration and telepathy.
- Wonder Child: Shades of this. Doctor Who media varies on whether or not Time Lords are interfertile; at the very least, human/Time Lord children are unusual enough that Eight asks Susan exactly how she managed it. (She's a bit embarrassed by the question.) Subverted in that, while Alex is clearly bright, he's no Time Lord, and is missing a number of abilities they otherwise have from birth.
Dr. Elizabeth Klein
Dr. Elizabeth Klein [Restored Universe] (Seventh Doctor)
Voiced by: Tracey Childs (2012, 2013)UNIT's scientific advisor, and the regular-universe counterpart of a very nasty alternate-universe Nazi officer. The Seventh Doctor's been keeping an eye on her just to make sure she's nothing like her alternate self, and she's absolutely not happy about it. But while being similar in temperament to her "other" self, this Klein is far more personable than her former incarnation, and most importantly not evil. For tropes pertaining to the alternate Klein, see her entry under Big Finish Doctor Who Villains.
- Badass Normal: Klein really is not fazed by Daleks, Sontarans, or even Nazis.
- Cosmic Retcon: The end result of a major cosmic retcon. This is treated like a big secret to be kept from her in "UNIT: Dominion", but Klein adapts rather well.
- Dr. Jerk: However, she is trying to improve herself.
- I Know You're Watching Me: "The Umbrella Man" (read: The Seventh Doctor) has been stalking her throughout her life at UNIT. It all turns out to be mostly harmless. Mostly.
- Jerk with a Heart of Gold: Klein's not the warmest of people, but she does make an effort to socialize with her co-workers and she definitely doesn't enjoy people suffering.
- Jumping Off the Slippery Slope: This seemed to happen in "Daleks Among Us", after Klein found out about her birth circumstances.
- Science Hero: She's quite the dab hand with a piece of technology, even keeping up with the Doctor's own contraptions and making use of them. She even learns how to pilot the TARDIS simply by watching Seven, in a rather eerie mirror of her alternate self, though she does have room to learn.
- Timey-Wimey Ball
- Tomato in the Mirror: Discovering about her alternate self was a bit of a shock to say the least. However, given the situation at hand, she moves on admirably from it.
Tamsin Drew (Eighth Doctor)
Voiced by: Niky Wardley (2010–2011)A failed actress who wants to leave her dreary life on Earth. Travels with the Doctor after Lucie leaves, but never really manages to get along with him. He outright rejects her as a companion when they first meet. Turns out taking her along anyway was a bad idea.
- Canon Immigrant: Mentioned in "The Night of the Doctor".
- Characters as Device: She's simply not suited for TARDIS travel... at least not with the Doctor. Her story line explored what happens when the wrong companion ends up with the wrong Time Lord, and is completely Played for Drama.
- Christmas Cake: As an actress, she's starting to get offered "mom" parts instead of "daughter" parts, and she hates it.
- Genre Blind
- Killed Off for Real
- Locked Out of the Loop: Though she never really bothered to investigate either, and she mistook a Dalek invasion fleet for medical volunteers. What an Idiot.
- Minion with an F in Evil: To the Monk.
- My God, What Have I Done?
- The Power of Acting: Invoked, but subverted, when the Doctor asks her to inflitrate into a monastery with some Improv. She's dreadful at it, and ends up posing as Maria von Trapp.
- Replacement Goldfish: For Lucie. Knows it and hates it.
Mary Godwin (Eighth Doctor)
Voiced by: Julie Cox (2009–2011)One of the Eighth Doctor's first companions, long before the regular timeline of the monthlies. Mary Godwin meets the Doctor at Lake Geneva, just before she would go on to write Frankenstein and, soon after, get married and become Mary Shelley. (Although she's already going by her fiancé's name most of the time) She's having difficulties in her relationship with Percy and his friends and jumps at the chance to escape it all for a bit.
- All Girls Want Bad Boys: She likes her men urbane yet wild, which is what attracts her to both Percy Shelley and the Doctor.
- Anachronic Order: Her adventures with young Eight take place mid-way through his travels with Gemma and Samson Griffin, long before those of Charley Pollard and Lucie Miller. This was done to put a bit of a breather between "To The Death" and "Dark Eyes", and to explore what Eight's life was like before "Storm Warning" (and "Terror Firma"). The older Eighth Doctor, whom she encounters first, is straight from the Time War era.
- Anguished Declaration of Love: To Eight, eventually. He just sort of stammers.
- Constantly Curious: She is a would-be science fiction writer, after all. And some of the advanced things she sees would be even more outlandish to her than to the average companion.
- Crazy-Prepared: She may be naive about the realities of time travel, but she does carry a small knife and a number of other useful things with her.
- Deliberate Values Dissonance: She has a bit of a laudanum habit. The Doctor doesn't exactly approve.
- Diary: Keeps one.
- Famed In-Story: The Doctor is especially concerned about not getting her killed, having plucked her out just before fame set in.
- Have We Met Yet?: She and the Doctor meet in the wrong order.
- Heroic B.S.O.D.: On her first trip, wondering what she was thinking coming to a place she didn't belong.
- The Maiden Name Debate: Whether or not she's using "Shelley" varies several times per episode, depending on how connected she feels to Percy at the time. Her hesitation in this regard is shown especially once she (inevitably) falls head over heels in love with Eight.
- Nightmare Fetishist: Slightly. She's morbidly impressed by some horrifying things.
- Silk Hiding Steel: She's very composed.
- Speculative Fiction: Considered, in story, as the mother of science fiction.
- Sympathy for the Devil: She became friends with a Cyberman. The Doctor later remarks that she tends to "side with the monster." It sets her up for the mindset behind the writing of Frankenstein.
- Wise Beyond Their Years: At eighteen, she's already had two kids and outlived one of them. She's take-charge and maternal and slapped a girl (apparently) her age for her childish insolence.
Philippa "Flip" Jackson (Sixth Doctor)
Voiced by: Lisa Greenwood (2011–present)Flip is a supermarket checkout girl, a "late teens, fluffy handbag, Essex girl" hungry for a more exciting life. She's definitely not the sharpest tool in the shed, but incredibly brave and adventurous, and willing to throw herself into any kind of danger just to help people. First meets the Sixth Doctor during a misadventure with Thomas Brewster (see above) and eventually becomes his companion.
- Book Dumb: She failed her driver's test, doesn't know the first thing about history, doesn't speak a word of French, and gets a little bit annoyed at Six's vocabulary.
- Chronic Hero Syndrome: She doesn't get scared easily, and even when she does, she still jumps in with both feet.
- Jumped at the Call: Very enthusiastically.
- Nice Girl: She may be a little snarky, but she's tremendously sweet.
- Pop-Cultured Badass:Flip: Well, um, I know that at Waterloo... Napoleon did surrender.
Napoleon: And who told you that, may I ask?
Flip: ... ABBA?
- Put on a Bus: At the end of "Scavenger", partially out of feeling like she's holding the Doctor back.
- The Bus Came Back: Returns for more adventures at the end of "Quicksilver".
- The Unfavorite: Both her parents have a clear preference for her younger brother, Phillip.
- Why Couldn't You Be Different?: In "Scavenger", Flip mentioned her parents wanted a boy for a child, and constantly questioned why she wasn't born one. She left when her brother came around, and her parents didn't seem to notice she'd gone. Worse? Her brother's name is Phillip.
Raine Creevy (Seventh Doctor)
Voiced by: Beth Chalmers (2011, 2012)Raine was created for Season 27 of Doctor Who before the series' cancellation. (Consequently, we don't know what actor would have played her.) She's a young burglar from a lower-class family who, armed with an affected posh accent and a healthy dose of sarcasm, decides to see what time and space are all about.
- Action Girl: She can wield a fencing foil, sword and axe proficiently, and she handles stressful situations in stride.
- Break the Cutie: A minor, self inflicted version; at the end of "Animal" in 2001, Raine uses a search engine to look up her family. She finds her father is dead by that point in time, and... well, she doesn't take it well. She takes some time off time travel to adjust to it.
- Classy Cat-Burglar: With an expertise in safecracking.
- Commuting on a Bus: She's a rare part-time companion, and sort of drifts in and out of the Doctor's life when she feels like it.
- Cultured Badass: Though her father was working class, Raine went to a finishing school that groomed her into a more high-class status. She strides in both classes, however.
- Fire-Forged Friends: With Ace.
- Little Miss Snarker: Especially towards UNIT.
- Rapid Aging: Before she was even born! Raine was barely a bump on her mother in "Thin Ice", at least until her mom was compelled to put on an Ice Warrior helmet that partially, physically transformed her into one of their ancient leaders. This shift affected Raine as well, though fortunately it only accelerated her birth without giving her any Ice Warrior traits, and she came out healthy.
- Uncanny Family Resemblance: She looks a lot like her mum, and Beth Chalmers voices both characters.
Lysandra Aristedes (Seventh Doctor)
Voiced by: Maggie O'Neill (2010, 2012)Sergeant of the Forge from 2020s. She was recruited by the Doctor to the Black TARDIS to battle the Elder Gods.
- A Day in the Limelight: In Companion Chronicles' "Project: Nirvana".
- Badass Normal
- Captain Smooth and Sergeant Rough: With Nimrod. Inverted with Sally Morgan.
- Chess Motifs: Weyland's bishop.
- Deadpan Snarker
- Defector from Decadence: Well, the Forge was hardly decadent, but she defected none the less.
- Fire-Forged Friends: With Sally.
- Have We Met Yet?: Meets Doctor out-of-order in his dealings with the Forge.
- Mistaken for Gods: By Beowulf and his ilk.
- Put on a Bus: She left to help in Africa, after leaving the Doctor's company, wanting to do some good.
- Undying Loyalty: To the Forge.
Sally Morgan (Seventh Doctor)
Voiced by: Amy Pemberton (2011–2014)A soldier from 2020s, Sally met the Doctor during a scientific study to remove fear from the human mind. When she proved loyal, smart and knowing when to obey and disobey orders, she was offered an opportunity to go AWOL. She joined the Black TARDIS team along with Lysandra.
- A Dayinthe Limelight: In Companion Chronicles' "Project: Nirvana".
- Badass Normal: Even when she first met the Doctor, she proved to be more than capable of handling herself against abnormal threats and forces. It's why the Doctor asked her to travel with him, after all.
- Babies Ever After: Has a couple of children with Hex, after the two of them finish traveling in the TARDIS.
- Cosmic Plaything: Her parents were killed and her entire life manipulated by Weyland, as part of his chess game.
- Hair of Gold, Heart of Gold
- Innocent Blue Eyes
- In-Series Nickname: Ace had a few choice names for her, including Sergeant Barbie and Private Benjamin.
- Last Girl Wins: With Hex.
- Raised by Grandparents: Due to her parents passing when she was young, Sally was raised by her grandfather from childhood. He passed on while she was in active duty, however.
- Why Did It Have to Be Snakes??: Her athazagoraphobia was often exploted by various psychic beings.
Dr. Liv Chenka
Dr. Liv Chenka (Seventh and Eighth Doctors)
Voiced by: Nicola Walker (2011, 2014–present)A medtech from the year 2865, who first meets the Seventh Doctor a few months after the Kaldor sandminer incident and, one Dalek war later, ends up as a companion to the Eighth.
- Ascended Extra: Though she wasn't exactly a background character, Liv was originally just a secondary character in a Seventh Doctor audio story, "Robophobia". Come Dark Eyes 2, however, she's a main character.
- Broken Bird: The war with the Dalek Empire leaves her so broken, she ends up fleeing to the literal end of the universe — something she's got in common with Eight at that point.
- The Bus Came Back: One that happened to be the belly of a starship, with some very nasty radiation exposure, all to escape the Daleks. Fortunately, it ends up with her in the Doctor's TARDIS.
- Damsel out of Distress: Like many a companion, Liv has a tendency of getting captured. She also has a tendency for giving as good as she gets, when it's expedient. She even manages to take the Master hostage with only a perfume bottle!
- Fish out of Temporal Water: Liv takes a while to really get the knack of being a time traveller, especially when in a timezone sufficiently different. By the end of "Dark Eyes 4", however, she's gotten a fairly firm grip on things.
- Gay Best Friend: Bas.
- Grand Theft Me: She's not the only one in her body.
- Human Popsicle: Her body gets frozen during her long voyage on the Sleeper Starship, and her mind is stored on a microchip.
- I Did What I Had to Do: Becomes a willing "traitor" for the Daleks when the Dalek Empire shows up to colonise the planet she's on, just so she can continue to do her job as a doctor.
- I Will Only Slow You Down: A non-lethal variety. Liv has been through tough scrapes, and when a situation calls for the Doctor to leave her behind to escape she can and will push him to do so, if only so that he can get the resources required to rescue her properly. It's saved both their lives, ironically enough.
- Letting Her Hair Down: At the start of "Dark Eyes 4", she has a day out with a man and gets a chance to be normal. Though she has trouble relaxing, she rather enjoys it and is disappointed when it has to end early.
- Science Hero: Part and parcel with being from an age of spaceships and androids. She actually has trouble adjusting to doing things such as tea manually.
- Single Woman Seeks Good Man: And the one guy she sort of fancies doesn't stick around for long.
- Space Clothes: She follows the Kaldor fashion and makeup trends before getting caught up in the Dalek war. She slowly adjusts to other garb after she joins the Doctor.
- Survivor Guilt: Surviving, and escaping, the Daleks left her with quite a bit of it, enough that she went on an expedition to literally the edge of the universe.
- Virtual Ghost: In an especially bizarre example of the trope, someone else's Virtual Ghost gets copied onto her memory chip, allowing that person to occasionally wake up her body from cryosleep and sabotage the ship without her realising it.
- What the Hell, Hero?: She gives one to the Doctor in "Dark Eyes 4" for leaving behind all the collateral damage in order to find his stolen TARDIS. They both give good arguments for their respective cases. She also doesn't appreciate the times he's made deals with the Daleks, whether or not he has any choice in the matter.
- Your Days Are Numbered: Due to having run away from the Dalek Empire under very unhealthy conditions. The Master reveals in "Dark Eyes 3" that exposure to his strands of retrogenitor particles have cured her of the affliction, however.
Hannah Bartholemew (Fifth Doctor)
Played By: Francesca HuntAn adventuress from the early 20th century who has an interest in the occult, Hannah meets the Doctor and Nyssa at a private hunt in Suffolk before an alien sentience starts possessing people and animals. Unlike most of the few Big Finish original companions in that she travels with the Fifth Doctor while he had one of his TV companions, this time with Nyssa.
- Action Girl: She is very far from being shy with her shotgun, and is eager to join the fray to assist those she likes. She was also quite at home in a death-trap of a tombship, even if she was out of her league when it came to the technology.
- Big Damn Heroes: In "Tombship"; despite the Doctor's squeamishness regarding guns and killing, her shotgun proves quite useful in dealing with the homicidal and virtually mindless aliens attempting to tear them limb from limb in an already deadly ship.
- Butch Lesbian: Sort of; her masculine habits, combined with the Word of Gay below, plausibly make her this.
- Death of Personality: In a heroic sacrifice to prevent a group of aliens from infiltrating the minds of a shady research facility, Hannah collapses an artificial reality upon herself, the scientists and the infiltrating aliens, removing her emotional mind and exuberance. Only her philosophy of the Order of the Crescent remains, aside from her memories. Unusually for this trope, Hannah recognizes she's unfit for travel in the TARDIS and requests to be left behind, where she may provide some good.
- I Will Only Slow You Down: When Hannah's emotional side is removed in "Masquerade", she insists that the Doctor and Nyssa leave her behind, turning down every offer for help in favor of providing assistance where she is.
- Jumped at the Call: Hannah is fascinated and excited at the concept of the TARDIS, isn't at all perturbed when she accidentally stowed away on it, and is outright disapointed when told that the Doctor was going to take her back to her own time, though she doesn't make a fuss. She perks up when she learns of the TARDIS' tendency of going anywhere but where the Doctor sets her to though.
- One of the Boys: Hannah effectively embodies this trope. She dresses like a man, eagerly takes part in what during her time were considered manly things, such as hunting, and takes offense at being brushed off with as of the "ladies". She also has a hard time sticking with formalities, preferring to just be called Hannah (though she does insist on "ms" over "miss" if one sticks at it). Humorously averted in "Masquerade", when she takes on the mindset of an Edwardian governess for a time.
- Reincarnation: She effectively believes in this as a member of the Order of the Crescent Moon, where those departed become shadows that guide those "in the light", until they too come back to life and hope to be guided in turn by those in the shadows. She's apparently believed this for most of her life too.
- Screw This, I'm Out of Here!: When the carriage she's leading is being attacked by a possessed elephant, she has the sense to jump ship while she can, even if it means leaving behind a disabled man who'd bought her reluctant help with the promise of a thousand pounds. She's not happy about it though, no matter how unpleasant he was.
- We Hardly Knew Ye: She sadly only appeared in three audio stories before definitively leaving the TARDIS, only appearing in the last half of one.
- Word of Gay: More implied, but the special features of "Moonflesh" point out that during the turn of the century in Boston, a lesbian movement took to being refereed to as "ms" (pronounced mizz) rather than "miss". This particular habit being something Hannah insists on, the production team ran under the train of thought that Hannah had just come back from Boston during that particular period under that "particular persuasion".
Mary "Molly" O'Sullivan, later Mary Carter (Eighth Doctor)
Voiced by: Ruth Bradley (2012–2014); Sorcha Cusack (2015)An Irish medical volunteer, working in France during World War I. She encounters the Doctor when he's rather suddenly found dying on the battlefield, and is quickly roped up in a full-scale Dalek invasion.
"Somewhere, behind the German lines, there were German girls, like me, looking at the terrible things our boys at done to their boys. Was I right? Eh? Was I right?"
- Badass Normal: Just a normal human, yet she tries to smack an Eldritch Abomination with a rolling pin, and walks into an impending explosion, knowing that it was the only way to safely defeat the Dalek Time Controller. She dies smiling.
- Berserk Button: Being called "Dark Eyes", especially once she figures out that it's more than just a nickname.
- Boisterous Bruiser: She punches Eight in the face.
- Bound and Gagged: In "The White Room".
- Brainwashed and Crazy: Spends most of "Dark Eyes 3" drugged to the gills and mind controlled.
- Broken Bird: Though healing well by 1918.
- Buffy Speak: A very rare example of The Stoic being fond of Buffy Speak, since she defaults to it even in stressful situations.
- Canon Immigrant: Mentioned in "The Night of the Doctor".
- Demoted to Extra: In "Dark Eyes 3", due to scheduling conflicts Ruth Bradley had from a movie deal. She eventually appears played by another actress in "Dark Eyes 4", explained in-story as Molly being now in her sixties.
- Eye Tropes: She's got the titular dark eyes: perfectly black irises. She hates that they keep coming back.
- Face Death with Dignity: Knowing that the Dalek Time Controller was tied to her own life, Molly calmly walks into an explosion, ending her life on her own terms. She dies smiling, even when she's pulled out of the rubble.
- Famous Last Words: "The high and mighty Doctor! Thinks he's in charge as always does he? Look at me, your not sacrificing anyone, I've decide for myself! You look after Liv now. You’re the Doctor, make people better!"
- Fish out of Temporal Water: She adapts quickly, but she much prefers her own time.
- Heroic Sacrifice: Attempts one in "Dark Eyes", but the Doctor ensures it doesn't go through. Pulls off a rather more successful one at the end of "Dark Eyes 4", to ensure the Dalek Time Controller ends with her. Even when Liv and the Doctor pull her out of the rubble, she's still smiling.
- Hiding In Plain Sight: Manages to escape Dalek notice by simply changing her name and staying out of trouble.
- Hospital Hottie: Though absolutely not in the mood to be one at first. She's fully aware that her being a sexy Hospital Hottie would only make things worse for the wounded soldiers, who have enough on their minds already. Also, at the start of her story she's full of nits anyway, and hasn't had a change of clothes (or a bath) in two weeks. Near the end of the war, she continues working as a nurse in London, and She Cleans Up Nicely.
- Insistent Terminology: "Tardy box".
- Letting Her Hair Down: When the war ends, she decides to treat herself to a vacation as the Doctor's companion, and mellows out a bit.
- Living MacGuffin: Throughout "Dark Eyes" and its sequels, Molly is sought out for some nefarious scheme or another. She adjusts to it fairly well by the third time.
- Malaproper: She consistently refers to any TARDIS she comes across as a "Tardy Box", with few exceptions. Though it was initially a mocking name, it slowly became something of an affectionate nickname. The Doctor's TARDIS didn't appreciate it much. She mostly drops it after forty years.
- Meaningful Name: When she starts mocking the Doctor's name, he informs her that her own name means "small fish dark-eyed". The nickname "Dark Eyes" sticks, although she's not too happy with it.
- My Country, Right or Wrong: Averted. She's horrified when she finds out that a man she's being treating is a member of the IRA ever since the failed Easter Rising.
- Put on a Bus: Because of the retro-genitor particles still inside her, Narvin takes her back to her own time to keep her safe from harm.
- Replacement Goldfish: Like Tamsin, she's a Replacement Goldfish for Lucie Miller. And like Tamsin, she's nowhere near willing to deal with Eight's emotional problems. However, things mellow out between them.
- Ripple Effect-Proof Memory: Ends up with one.
- Romantic Two-Girl Friendship: With Kitty, the lady she worked for. Entirely Played for Drama.
- Shell-Shocked Veteran: Has deliberately stopped making friends to avoid getting even more emotionally damaged.
- The Slow Path: Several times — the final time the Doctor meets her, she's in her 60's, and has spent forty years living in an alternate timeline under Dalek occupation.
- Spell My Name with a "The": She doesn't have time to put up with the Doctor, and she mocks him by addressing him as "The Doctor". This habit slowly drops the closer she comes to him, although she never truly stops the name.
- The Stoic: Doesn't ever let her emotions get out of hand.
- Sugar and Ice Personality: She's extremely harsh and self-reliant, and has taught herself to ignore her emotions; but she's definitely The Heart, and the reason she continues fighting is to save people no matter the cost.
- Survivor Guilt: Ohh boy. Once Eight realises she has just as much Survivor Guilt as he does, they start to bond over it a little.
- We ARE Struggling Together: In spite of the constant danger the TARDIS brings her, this is what helps Molly adjust and warm up to the Doctor.
Hector Thomas (Seventh Doctor)
Voiced by: Philip Olivier (2013–2014)On New Year's Eve in the 2020s, Hector Thomas found himself in a parking lot. Out of jail and wanting to make a name for himself, he began an empire of restaurants, clubs and other businesses. Trouble was, he began to run into the Finnegans, a three family group who were not only buying out other clubs, but had an odd tendency of not dying out...
"You must really, really want to meet me. Grab yourself a glass of vino. There’s a bottle open on the side."
- Darker And Grittier: Compared to Hex - whereas Hex would back away from any kind of killing, Hector has had many a Finnegan cut down, and it's implied he was fairly aggressive in getting to where he was. Both Hex and Hector have had a thing for Ace at the start too. However, while Hex came down gradually from his crush, Hector... pushed the line a bit in his first outing. (Ace was clearly grieving for a lost friend whom Hector reminded her of, but Hector was fairly quick to invite her to his flat and do a bit of kissing. Fortunately, the mood changes and things don't progress any further into Squick territory.)
- However, this turns out to be part of the persona inserted into Hex's head when Koloon brought him back to life. He lightens up considerably the further along he comes past what was to be his expiration date.
- The Don: The crimes Hector and his men commit on-screen are least stealing high-tech and foreign weaponry, property damage, and many murders of the Finnegans. The same Finnegans, in fact, to the point he's getting creative with how they're killed and where they're dumped. It was also mentioned that the first club he came to own had an owner that suddenly went missing, although it's ambiguous if it was his or Koloon's work.
- A God Am I: Though he initially takes up the guise of Dionysos for a benign purpose in "The Mask of Tragedy", utilizing an alien psychic mask, the damaged mask gives him this impression of himself. It goes badly for him.
- Heel–Face Turn: In a sense. In his first story, Hector starts thinking of ending conflicts with the Finnegans and just settling with being a business owner. His time on the TARDIS shows that, while he is still a bit gritty, he genuinely wants to do good and finds the constant death around him abhorrent, far from the gangster he was before. Even he recognizes the changes he's going through come "Signs and Wonders".
- Identical Stranger: He looks and sounds exactly like Hex, save a slightly different accent. Their personalities are completely different however. That's because he is Hex, but with a personality built from a life in a book.
- I Just Want to Be Normal: The memories of his old life fading away, and Ace's constant attempts to jog his memory, make him want to just settle down and make new memories he knows are his own. He gets his wish, and then some.
- Loss of Identity: Happens to Hex when Lily Finnegan smashes the bottle holding his memories and self, leaving him as Hector from then on. The Doctor doesn't take it kindly. Ace tries to get around that, though Hector doesn't appreciate it.
- Hector himself goes through this the longer he lives, his old memories becoming indistinct and difficult to tell if real or not to him.
- Mind Rape: Is the unfortunate and constant subject of this, helped in no part from having a great hunk of his past removed from his mind. From being possessed by the Swarm, being torn into by digital prawns, to being given delusions of grandeur by a mind-affecting mask, Hector's mind comes under a lot of abuse.
- Split-Personality Merge: With Hex, courtesy of Genny Greenskin. Hex comes out as the dominant part of the personalities, effectively reviving him from the dead.
- That Man Is Dead: Though he recognizes he won't be able to measure up to Hex in Ace's eyes and that Hex was a good man, Hector is quite fine with being the man he is. However, he doesn't appreciate being constantly compared to Hex in a negative light, nor attempts to jog Hex's memories in his head.
- Unfazed Everyman: It takes a lot to faze Hector after he starts traveling in the TARDIS.
- Send Me Back: That said, he doesn't really adapt to adventures in the TARDIS very well.
- What the Hell, Hero?: Has this reaction towards Ace and Seven every so often when confronted with the death and manipulation that follows them around. It simply rubs him the wrong way at how aloof they seem to treat their adventures.
- Your Days Are Numbered: He originally supposed to live for a single year, from New Years to New Years. However, nobody could have foreseen that Ace would give Hector a trip in the TARDIS....
Constance Clarke (Sixth Doctor)
Voiced by: Miranda Raison (2015–)Member of Women's Royal Naval Service from World War II.
- Action Girl: The Doctor notes that she "tends to save people", something that served her well in the wartime.
- Alliterative Name: Constance Clarke.
- Braids of Action: Goes from 1940s hair to one long braid, as evidenced by the covers.
- Chekhov M.I.A.: Constance constantly worries about her husband, a spy in deep cover behind enemy lines. After a particularly long absence of messages from him, she starts asking everyone who may know something about whether he is dead or not. Nobody gives her a straight answer on the subject. When it turns out that her husband has been sending her messages, ones that her superiors have been denying her, Constance decides to leave with the Doctor.
- Mama Bear: Though not a mother, Constance is very protective of the Wrens under her guidance, and does not enjoy seeing them mistreated.
- Science Hero: A more moderate one, but she's fairly familiar with a number of complicated scientific concepts as part of her work in World War II, including parallel realities.
- Unfazed Everyman: Constance is a very difficult woman to shake, even when presented with places and concept that are well away from what she would have experienced in the 1940s. Even when she is shaken, though, she recovers quickly.
Helen Sinclair (Eighth Doctor)
Voiced by: Hattie Morahan (2015–)A classical linguist from 1963. Meets the Doctor, accidentally gets blamed for the biggest museum heist in modern times in the process, and runs away with him.
- Badass Gay: She's not a physical fighter, but can hold her own in stressful situations.
- Deliberate Values Dissonance: The amount of discrimination she faces as a gay scholar in the 60's has left her frustrated with the world, and she's very glad to discover that her new friends in the TARDIS aren't as close-minded.
- Internal Homage: Helen is based on Who producer Verity Lambert.
- Lady And A Scholar: Kind, polite, socially adept, and in love with her work.
- You Can't Go Home Again: She tries, and ends up ruining what was left of her chances.
A few other characters have been introduced which, although not technically companions, meet the Doctor on occasion:
DI Patricia Menzies
Voiced by: Anna Hope (2008–2011)A Mancunian detective-inspector who keeps encountering the Sixth Doctor.
- Have We Met Yet?: She and Six meet in the wrong order, and realizing the implications for the Web of Time, they both decide to keep it a secret from each other.
- Bavarian Fire Drill: She spends a large chunk of one adventure pretending to be the Doctor's next regeneration.
- Deadpan Snarker: Seriously.
- Great Detective: She's really very good at her job.
- Oop North: From Manchester.
- Nerves of Steel: She pretty much treats the Doctor's adventures as just another day at work.
- Reasonable Authority Figure: She's very willing to listen to the Doctor's story, once she figures out that he's telling the truth.
- Unfazed Everyman: She grasps the basics of time and space travel very quickly, and doesn't let it keep her from getting the job done. She even starts policing the aliens among us because she knows they can't go knocking on the door of regular authorities. Pro bono.
Voiced by: Natalie Burt (2012–2014)An inventor from the 1970's and almost-companion of the Eighth Doctor, until she got blown up by Daleks in an aborted timeline. In the restored timeline, she was supposed to be hit by a car instead, but got rescued — by the Master, of all people, who promptly took her on as his brainwashed companion.
- Brainwashed and Crazy: As the Master's puppet/assistant. Though she's more than willing to assist him, he has left her with a few triggers should she step even a little out of line for him.
- Came Back Wrong: After dying in "Dark Eyes", a change in timeline resurrects her. The Master gets to her before the Doctor can.
- Eye Scream: The Master uses her as his assistant when he's posing as an optometrist, and merrily collecting people's eyes.
- Face Death with Dignity: Averted.
- For Science!: Though her scientific curiosity was innocent enough, it was the same aspect which lead to Sally being manipulated twice by Time Lord parties, the Master in particular corrupting her through it.
- Gadgeteer Genius: For the Ides Scientific Institute.
- Green-Eyed Monster: As brilliant as she is, Sally is, deep down, aware of just how replaceable she is in the grand scheme of things to the Master. The fact that Molly, some random girl from an old age, isn't really doesn't do well for her, although she knows better than to act on any jealousy she has.
- Have We Met Yet?: She first hears of the Doctor when he sends a message back into the past for her, long after he's met her, and in a timeline that never happened anyway.
- More Than Mind Control: Although regular-timeline Sally was a good woman, the Master only had to tap into her ambitious nature to turn her into his companion. A smidge of hypnotism was all it took to make her evil.
- Pet the Dog: Going back to see if Molly as a cure or not to the Eternal Warriors just before she left in the Master's TARDIS in "The Death of Hope" stands out as one.
- The Resenter: Towards Molly.
- What Measure Is a Mook?: Liv points out that Molly, a working class nurse, is more important to the Master than Sally's educated, loyal self, and that the Master is a Bad Boss who'd dispose of her without a second thought. Surprisingly, this is untrue — the Master appears genuinely fond of Sally, and is upset at her death. While he doesn't stop to grieve, it's implied he's hunting her killer for revenge.
