Rose Tyler

 The first nineteen years of my life, nothing happened. Nothing at all, not ever. And then I met a man called the Doctor.

 Played by: Billie Piper (2005-06, 2008, 2010)

Young Rose played by: Julia Joyce (2005)
—Travelled with the Ninth and Tenth Doctors

A shopgirl from 21st century London, Rose was the first companion seen in the new series. Left after series 2, returned for series 4. Madly in love with the Doctor, which is awkward for everyone involved and leads to the Doctor making up a "falling in love not allowed" rule for his subsequent companions. (This works about as well as you would expect.)

  • A God Am I: During her stint as the Bad Wolf.
  • Ambiguously Bi: According to Billie Piper, Rose would be in love with Thirteen. It's not clear if this means Rose is Bi the Way or if she would just be sticking with the Doctor.
  • Baby Got Back: Or as Cassandra puts it, "Nice rear bumper".
  • Beware the Nice Ones: Series 1 finale counts.
  • Book Dumb: Frequently said to have done very poorly in school. Of course, she's also a Guile Hero.
  • But for Me It Was Tuesday: The novelization of "Rose" suggests that she didn't remember the Tenth Doctor, his face at any rate, from "The End of Time" because, growing up in a working class neighbourhood of London, she's learned to tune out drunks ogling her.
  • Clingy Jealous Girl: Forms most of the tension with Sarah Jane when they first meet, and she really doesn't seem to like the idea that the Doctor has had female friends other than her in the past (or may have in future). Both IDW and Titan Comics have said that during multi-Doctor events, they try to either exclude Rose outright or minimize her presence because of this trope.
  • Determinator: She will cross universes (something which the Doctor said was impossible) to be with the Doctor again.
  • Entitled to Have You: Even as she went gallivanting across the universe with the Ninth Doctor, and openly flirted with him, she still expected Mickey to patiently wait for her back in London.
  • Everyone Loves Blondes: Lampshaded by Martha and Jack:

Martha: Is that what happens though, seriously? You just get bored of us one day and disappear?

Jack: Not if you're blonde.

Martha: Oh she was blonde! Oh, what a surprise.

  • Fatal Flaw: Selfishness. She may be one of the nicest and most helpful girls you could ever meet but there are many moments where she's prone to looking after her nothing but her own wants, consequences be damned. Ultimately what does her in in "Doomsday" as she was ready to sacrifice being with the family she'd always wanted if it meant staying with the Doctor.
  • First Girl Wins: Rose is one of the few companions that The Doctor has expressed obvious romantic affection for, eventually ending up with his half-Donna clone. In a very strange (but sweet) way. The writers have explicitly said that the Clone told her "I love you" when they hooked up.
  • Fun Personified: In sharp contrast to the gloomy Nine.
  • Forgotten First Meeting:
    • Met the dying Tenth Doctor on New Year's Day 2005 but he kept his face in the shadows.
    • The War Doctor saw her face when the Moment took the form of the Bad Wolf but forget the details owing to the out-of-sync timelines.
  • Girl Next Door: Quite possibly the most normal companion, before meeting the Doctor, in the whole series.
  • Grand Theft Me: To Cassandra's chagrin. "I'm a chav!"
  • Heroic Sacrifice: Series 2 finale counts, though she's technically not dead.
  • Humanity Is Infectious: Her humanity goes a long way in healing the Doctor's PTSD and influences the Tenth Doctor's attitudes.
  • It's All About Me: Has some very self-centered moments, especially regarding Mickey and the Doctor. She naturally gets called out on this. Whether or not it stuck depends on the viewer.
  • Love Confession: She tells the Tenth Doctor this. While he does not say it back, his clone whispers it back in her ear (according to the writers). She stays with the clone in the alternate universe.
  • Love Redeems: Her love helps the Ninth Doctor move on from the Time War.
  • Living Emotional Crutch: She is this to the Ninth Doctor while the Tenth Doctor becomes her's.
  • The Lost Lenore: To Ten in Series 3.
  • Morality Chain: For the Ninth Doctor. For the Tenth, not so much...
  • Nice Job Breaking It, Hero: Maybe? It's said that the Reality Bomb will destroy The Multiverse with Rose returning to her universe to warn the Doctor, blasting several holes in the dimensional walls in the process. Given the timey-wimey nature of the show, some media implied, but never outright confirmed, that in doing so, Rose allowed the Bomb's detonation to affect other realities.
  • One Head Taller: Nine and Ten tower over her.
  • Pink Means Feminine: Wore a lot of pink in Series 1.
  • Protagonist-Centered Morality: Has her own Big Finish series, Rose Tyler: Dimension Cannon.
  • Replacement Goldfish: Implied to be one to some degree. The Doctor's first companion, his granddaughter Susan, was named "Arkytior" which meant "Rose" in Gallifreyean.
  • Static Character: After Series 2, Rose doesn't go through any real changes as a character even though it's been several years since she and the Doctor last met and even more for her due to time passing faster in Pete's World. She even gets everything she ever wanted at the end of her arc, giving her no real reason to change.
  • Stranger in a Familiar Land: Helps that she missed a year. In Series 2, Jackie voices her worries that Rose will be so changed by her travels that she won't recognize her own daughter.
  • She Is Not My Girlfriend: To the Ninth Doctor, mainly.
  • Too Much Alike/Toxic Friend Influence: Had some shades of both with Ten in Series 2. They were often a bit too comfortable around each other and didn't exactly encourage the other's best traits.
  • Took a Level In Badass: In Series 4, she's got a BFG (as in as big as her) and blows up Daleks like they're nothing.
  • Trademark Favorite Food: Chips (french fries).
  • Tsundere: The "sweet" type.
  • Unreliable Narrator: Everything she says about her death.
  • Unwitting Instigator of Doom: Indirectly responsible (along with "Sexy") for the return of the Master (and by extension, Professor Lazarus' rampage) and Miracle Day.
  • What the Hell, Hero?: Prone to giving these to the Ninth Doctor.

Mickey Smith

 Played by: Noel Clarke (2005-06, 2008, 2010)

Young Mickey played by: Casey Dyer (2005)
—Travelled with the Ninth and Tenth Doctors

Mickey at first was the "abandoned boyfriend" of Rose during the first series. This, however, didn't stop him from running around for a few adventures during that series anyway. Later joined in the TARDIS crew as a theoretical Companion for a few episodes early in the second series, only to stay behind off-planet (sort of). Returned at the end of the second series, as well as the end of the fourth and briefly in the 2009 specials.

  • All Love Is Unrequited: Played straight with Rose, later averted with Martha, whom he married.
  • Always Second Best: To the Doctor. But most people would feel this given the Doctor.
  • Badass Beard: Once he starts fighting aliens freelance.
  • Badass Normal: Eventually.
  • Black and Nerdy
  • Butt Monkey: The Doctor considers him an idiot, his girlfriend gives him little to no respect, his girlfriend's mother accuses him of murder when her daughter goes missing, Jack starts making fun of him within ten seconds of meeting him, and even K-9 gets to throw in a bit of snark while informing him, "We are in a car." Hell, his own parallel-universe equivalent finds him embarrassing, and this is a guy who considers himself a badass because of the number of parking tickets he's accrued.
  • Hidden Depths: He's a very good hacker.
  • Humiliation Conga: His girlfriend runs off with an alien after basically snarking how useless he was. She goes missing for a year and the police actually haul him in five times. And the Doctor keeps calling him Ricky and turning into better looking guys while hauling his girlfriend all over the cosmos. It gets better...
  • I Choose to Stay: At the end of "The Age of Steel," he stays behind in the alternate universe to help his dead alternate self's boyfriend (long story) fight the Cybermen and take care of his parallel-universe grandmother. Then he comes back for good at the end of "Journey's End" (after returning briefly in "Army of Ghosts" and "Doomsday").
  • Master Actor: Infiltrated Torchwood One for months with not even a single person suspecting him. For reference, Rose was caught within half an hour.
  • Meaningful Name: Got the mickey taken out of him pretty regularly.
  • My Name is Not Ricky: It's Mickey!
  • Pair the Spares: With Martha Jones.
  • Parental Abandonment: His father just up and left one day.
  • Punny Name: Perhaps not intentional, but to "take the mickey" out of someone is to take any fight/vigor/self importance out of them by mocking them, and Mickey does have to put up with a great deal of mockery and bullying from Rose and the Doctor (mostly Nine), and Jackie at first.
  • Poke the Poodle: Ricky Smith is London's Most Wanted... for parking violations.
  • Raised by Grandparents: His father left and his mother committed suicide, leaving him to be raised by his grandmother.
  • Rebel Leader: Alternate Mickey. (It's Ricky.)
  • Salt and Pepper: Alongside his partner in crime, Jake.
  • Taking Up the Mantle: When his alternate self dies, Mickey simply assumes his identity and continues the fight.
  • Token Minority Couple: With Martha.
  • Took a Level In Badass: Multiple. To wit, from lovable but aimless boyfriend to a capable hacker and fully-fledged companion. Ends up fighting Cybermen in an alternate reality and respected member of that reality's Torchwood, and finally earns his happy ending with a woman who saved the world with the power of story.
  • Where Da White Women At?: He and Rose seem quite happy, though not exactly soulmates.

Adam Mitchell

 When I was eight, I hacked into the US defence network… you should have seen them running about!

 Played by: Bruno Langley (2005)
—"Travelled" with the Ninth Doctor

Short-lived companion; a Teen Genius from 2012. Holds the dubious honor of being the only companion to be evicted from the TARDIS for bad behavior.

  • Arbitrary Skepticism: Has a job that revolves around alien artifacts, but sees alien abduction stories as nonsense.
  • Big Bad: For IDW's last Doctor Who comic, Prisoners of Time.
  • Butt Monkey: He doesn't get a lot of respect.
  • Deconstruction: Intentionally written as a troublemaker to show what kind of person makes for a bad companion.
  • Evil Is Not a Toy: Returns as the Big Bad in IDW's last Doctor Who comic where he learns what small potatoes he is compared to the Master.
  • Freudian Excuse Is No Excuse: Twice in Prisoners of Time.
    • He claims he was stealing alien technology to heal his sick mother. Even if it's true, the Ninth Doctor doesn't consider it a justifiable reason to alter history and play god.
    • Taken even further in the Eleventh Doctor issue where Eleven, far more forgiving a man than Nine, outright says that what he did to Adam was wrong and that he's sorry, but getting snubbed doesn't even begin to justify working with the Master.
  • Insufferable Genius
  • Teen Genius
  • Time Travel for Fun and Profit: Why the Doctor kicks him out of the TARDIS.

Captain "Jack Harkness"

 Mickey Smith: What are you captain of, the innuendo squad?

 Played by: John Barrowman (2005, 2007, 2008, 2010, 2020)
—Travelled with the Ninth and Tenth Doctors. Gloriously returned during the Thirteenth Doctor's run.

51st century native Jack (not his real name) is an omnisexual former Time Agent, turned time-traveling con-man, turned galactic hero when he met the Doctor -- and, eventually, turned immortal. Madly fancies the Doctor, although it doesn't exactly stop him from also hitting on Anything That Moves. Got his own spin off.

For tropes pertaining to Jack in Torchwood, see that series' character sheet.

  • Age Without Youth: Expresses some worry about having an extremely slow version of this, since despite little actual signs of aging he's begun to find white hairs. To top it off, he is implied to eventually mutate into the Face of Boe after billions of years.
  • Anti-Hero: Though a more family-friendly variant than on Torchwood.
  • Anything That Moves: Has a penchant of flirting with everyone he meets, even when the world is ending -- to the Doctor's constant frustration.
  • Badass Longcoat: Of The World War II greatcoat variety.
  • Boldly Coming
  • Casanova
  • Catch Phrase / Phrase Catcher: Some variation of the following exchange will be said when he's around:

Jack: (To his latest object of attraction) Captain Jack Harkness, and who are you?

The Doctor: Stop it.

Jack: I was just saying hello!

  • The Charmer
  • Chekhov's Gunman: In "The End of The World,", as he's the Face of Boe. (Russell T. Davies refuses to elaborate on whether or not they're actually the same person, as it would ruin the joke.)
  • Chivalrous Pervert: Never tries anything with someone who's already in a monogamous relationship, and is very willing to be strictly monogamous if the right person comes along. Is kind and considerate towards his fuckbuddy Ianto in Torchwood and, after a while, asks him out and starts a proper and very sweet relationship with him. Has been married at least once, although his immortality has made him a bit wary of commitment.
  • Even the Guys Want Him: As a YouTube comment put it,

If you're a guy and you like guys, you're gay.

If you're a guy and you like Jack, you're human.

Donna Noble

 Didn't I ever tell you? Best temp in Chiswick -- 100 words per minute!

 Played by: Catherine Tate (2006, 2008-10)
—Travelled with the Tenth Doctor

Donna was a temp worker from Chiswick, London in the 21st century. She first met the Doctor when the Racnoss queen fed her an ancient energy normally only found inside TARDISes, and the TARDIS pulled her into itself as a result. Played by established comedienne Catherine Tate. Originally a one-off character for the 2006 Christmas Special, Donna returned as a regular companion for the fourth series as well as a role in the Tenth Doctor's last two specials.

  • Abusive Parents: Donna's mom, Sylvia, is verbally abusive to both Donna and Wilf (Donna's grandfather) in a depressingly realistic way. The Doctor is actually shocked when he realizes the extent of it, and tells Sylvia to stop it.
  • Ascended Extra: Was only ever meant to appear once.
  • Badass Abnormal: Temporarily, as the Doctor Donna. This also protects her from the Master's scheme in The End of Time.
  • Badass Bureaucrat: She was an office worker prior to being a companion, and her office skills prove extremely useful in "The Sontaran Strategem", "The Doctor's Daughter" and "Journey's End". Her ability to understand office files, work a calendar system and type 100 words a minute ends up saving the universe several times over.
  • Badass Normal: The Doctor infiltrated (and later broke into) a corporate office building with psychic paper and the sonic screwdriver. She did the same with little more than really good BS skills and an absurd amount of patience.
  • Better as Friends: With the Doctor, to his great relief. In fact, he wouldn't have let her into the TARDIS otherwise, because he was very tired of everyone falling in love with him. (They share one snog, but it's completely for comic relief and not remotely romantic. And she does find him attractive, but not in that way.)
  • Boisterous Bruiser: A rare female example.
  • Catch Phrase: "Oi!"
  • Character Development: Oh, very much. It's a testament to Tate's acting talent when Donna's mom and grandfather beg the Doctor to let her keep her memories, as traveling with him made her a better person -- and we see her revert to her shrill, gossipy, idiotic old self when those memories are erased.
  • Christmas Cake: Donna is one of the very few companions older than 30.
  • Clingy Jealous Girl: Averted; the Doctor expects the same snarking he got from Rose/Sarah, but when Donna meets Martha they just shake hands and get along fine, gossiping about the Doctor's personal failings. Donna's concerns are more that she might lose her position as the Doctor's companion.
  • Crazy Prepared: Drove around ready to travel with the Doctor with every type of clothing she might ever need after her debut episode just in case he showed up one day and made her a companion.
  • Failing a Taxi: In the Christmas Special where we first meet her, she tries to hail a taxi and gets one driven by a Mook, forcing the Doctor to save her.
  • Fiery Redhead: Scorching!
  • Flowers for Algernon Syndrome: Played With. Donna is frequently horrified by the amount of responsibility the Doctor has, but copes by going back to being snarky for the start of each new adventure. This means that her Character Development is gradual and zig-zaggy. It makes it all the more horrifying when we see her go back to her old old self.
  • Good with Numbers: It's more than just math, though -- she's spent most of her life temping, and she's gotten ridiculously good at it, having gained a knack for spotting patterns in numbers not even the Doctor would notice.
  • Half-Human Hybrid: In "Journey's End", she saves herself from Dalek-inflicted doom by splicing her DNA with the Doctor's. She then indulges in Techno Babble, yelling like the Doctor, and hijacking the Dalek's motor commands to make them spin in circles. Fun is had by all, but it does not last.
  • Heterosexual Life Partners: During their brief time together, it was clear that Martha was under Donna's protection and you'd best not talk smack about her new best friend.
  • Hidden Depths: Has amazing bureaucratic skills and can type 100 words per minute.
  • I Just Want to Be Special: Her character arc in a nutshell.
  • Inferiority Superiority Complex
  • Large Ham
  • Mismatched Eyes: Real ones.
  • Missing the Good Stuff: In "The Runaway Bride", her first appearance, she has (somehow) managed to avoid all of London's previous encounters with extraterrestrials.
  • Morality Chain: Explicitly considers herself one for the Tenth Doctor.
  • Pity the Kidnapper: When she was in peril, she often made the bad guys regret putting her there, even without the Doctor's interventions.
  • Platonic Life Partners: With the Doctor much to his relief.
  • Plucky Girl: Explicitly called this by the Doctor.
  • Redheaded Hero
  • Red Pill, Blue Pill: "Turn Left".
  • Refusal of the Call: When the Doctor first asks her if she'll travel with him, she says no -- being, understandably, weirded out by his Tranquil Fury. She later regrets this and begins searching for him.
  • She Is Not My Girlfriend: Quite honestly so this time.
    • Like Brother and Sister: She and the Tenth Doctor have this dynamic, both trading sarcastic barbs constantly but obviously caring deeply for each other. The Doctor outright calls her his best friend.
  • Shoe Slap: Declined. In 'The Poison Sky', she was supposed to use a shoe to knock out a Sontaran. Thing is, she'd only wear trainers, and those don't have quite the kick needed. Fortunately, Percussive Maintenance leaves mallets around when you need them.
  • Snap Back: Justified as allowing her to keep her memories of the Doctor would cause her mind to burn up.
  • Tsundere: The "harsh" type. Pompeii, the Ood, the Doctor in distress and her own two alternate dimensions trigger the dere side.
  • Unwitting Instigator of Doom: Begging the Doctor to save someone in Pompeii led to the Twelfth Doctor giving himself the face of Caecilius and bringing Ashildir back to life. Nothing good came about from Ashildir being immortal and it led directly to Clara's death.
  • Victory-Guided Amnesia: To prevent her brain from burning up.

Dr. Martha Smith-Jones

 I travelled across the world. From the ruins of New York, to the fusion mills of China, right across the radiation pits of Europe…

 Played by: Freema Agyeman (2007-08, 2010)
—Travelled with the Tenth Doctor

Martha was a medical student when her hospital ended up on the Moon in the early 21st century. She and the Doctor saved each other's lives a few times that day, and she ended up as the third female (second regular female) companion of the Tenth Doctor. Tries hard not to fall in love with him, but fails rather spectacularly at that. After she left the TARDIS, Jack Harkness pulled some strings to get her a job with UNIT in what seems to be Harry Sullivan's old job. She remains friends with Jack, and has popped up in a a couple of Torchwood episodes helping out Torchwood Cardiff. In the comics universe, she left UNIT to become a freelance monster fighter but still seems to work with them.

  • All Love Is Unrequited: Develops a crush on the Doctor big enough to rival Rose's feelings. He acknowledges her feelings, after a while, but nothing ever happens. By the time she's no longer a companion, she's working on getting over him and they go back to being just friends.
  • Always Second Best: How she feels about replacing Rose. Ironic really considering that in many areas, she was Rose's better.
  • Better as Friends: Leaves the TARDIS when she realizes the Doctor's never going to like her "that way". In season 4, she's recovering from her crush on him, and they're much happier together just being friends.
  • Big Damn Kiss: Eventually kisses Jack Harkness, even though she's engaged at the time, simply because "everyone else has had a go". Jack just sort of stares at her.
  • Black and Nerdy: Medical student, natch.
  • Clingy Jealous Girl: A mild case, but more so when Rose is brought up. Once she's getting over her crush on him, she's actually really happy when the Doctor and Rose are reunited.
  • Determinator: At the end of Series 3.
  • Dude Magnet: Aside from the Doctor, there wasn't a guy who could keep his eyes off Martha.
  • Foil: To Rose. Rose was working class and forcefully separated from the Doctor while never letting go of her feelings for him. Martha was upper-middle class and still planned to go upwards in the world and eventually moved on from her affections to the Doctor.
  • Get a Hold of Yourself, Man!: To John Smith in "Human Nature / The Family of Blood".
  • Hospital Hottie
  • It's All My Fault: Clearly blames herself for the Master's return, having prodded Yana to open the Fob Watch, and not telling her family about the Doctor put them in danger.
  • Just Friends: With the Doctor, to her great frustration.
  • Meaningful Name: Martha Jones. Who leaves the TARDIS when the Doctor is still jonesing for Rose.
  • Middle Child Syndrome: Often hinted to be the victim of it.
  • OOC Is Serious Business: Although not The Stoic, Martha does keep a grip on her emotions. When she gets angry ("The Sound of Drums") or really scared ("The Sontaran Stratagem"), you know things are very bad.
  • Pair the Spares: With Mickey Smith. What happened to her engagement to Thomas Mulligan from Series 4 has never been explained.
  • Replacement Goldfish: It doesn't take very long for her to feel as though she's simply this for Rose.
  • Technical Pacifist: Doesn't carry a gun, but has a position of command in a military organisation.
  • Took a Level In Badass: In The Year That Never Was. Joins UNIT right after.
  • Uncanny Family Resemblance: Actor Freema Agyeman first appeared as a Torchwood London employee; a character later retconned into Martha's identical cousin Adeola.
  • Undying Loyalty: Will stand by the Doctor no matter what. She even endured months of racial harassment and walking a ruined wasteland for a year without asking for anything in return.
  • Walking the Earth: During the Year That Never Was.
  • What the Hell, Hero?: The Doctor's reaction when he hears about Martha's plan to blow up the Earth to stop a Dalek plot.
  • Yaoi Fangirl: As revealed in Torchwood, where she takes interest in Jack and Ianto's "dabbling".
  • You Look Familiar: As above.

Astrid Peth

 Mr. Capricorn? I resign!

 Played by: Kylie Minogue (2007)
—Travelled with the Tenth Doctor

A one-shot character in the 2007 Christmas special. A struggling waitress from the planet Sto on board the Starship Titanic.

Wilfred Mott

 Every night, Doctor, when it gets dark, and the stars come out, I'll look up on her behalf. I'll look up at the sky, and think of you.

 Played by: Bernard Cribbins (2007-10)
—Travelled with the Tenth Doctor

A newspaper salesman from 21st century Chiswick, London. Originally a one-off character in Voyage of the Damned, Wilfred was eventually revealed to also be Donna Noble's grandfather (a last-minute rewrite due to the actor hired to play Donna's father dying). This resulted in quite a few recurring roles throughout the fourth series, leading to fan-favorite status for the character and finally full-fledged companion status in "The End of Time", the Tenth Doctor's final story.

  • Ascended Extra: Originally intended to be named "Stan" for "Voyage of the Damned" and never show up again, this changed when the actor playing Donna's father passed away.
  • Badass Grandpa: The entire population of London evacuates because they're afraid aliens will invade, and Wilf stays in his stall. Daleks are invading the Earth, and Wilf's first thought is how to disable them... with a paintball gun. He even proves a crack shot with an asteroid laser.
  • Badass Normal: Dalek. Paintball gun. It didn't work, but that's still quite a few levels of Badassness above the norm.
  • Chekhov's Gun: Owns one, and convinces the Doctor to accept it as a gift.
  • Cool Old Guy: Played straight whenever he's paired with Donna or the Doctor.
  • Like a Son to Me: Despite being the Doctor's junior by more than 800 years.

The Doctor: "I'd be proud."

Wilf: "What?"

The Doctor: "If you were my dad."

  • Nice Guy: Taken Up to Eleven! Wilfred Mott is compassionate, empathetic, funny, level-headed and fiercely loyal. He rarely prioritises himself over other people, and isn't ashamed of the fact that he never killed a man while in the army. Wilfred's only moments of malice are towards the Master, and brought on by the fact that he is convinced the Master will kill the Doctor, whom Wilfred deeply likes. He is compelled into action by the fact that someone else needs him, rather than what another person can do for him. He's willing to undergo fatal radiation poisoning so that the Doctor can live.
  • Parental Substitute: Is this to Donna. After her father died, and given her mother's aloofness, she always turns to "Gramps".
  • Prophecy Twist: "He will knock four times." The Doctor was absolutely sure that it referred to the Master (and, admit it, so were you.) Instead, after the Master is defeated, Wilf politely knocks four times on the door of his glass cage, hoping the Doctor will let him out. Wilf previously trapped himself in the cage to save a random guy's life. The only way the Doctor can get him out is by killing himself, which, although Wilf protests, he does with quiet resignation.
  • Older Sidekick: Obviously more than qualifies in the real world; he's more than twice David Tennant's age. In fact, Bernard Cribbins is the oldest actor to have played a companion on the show. In-universe, the Doctor is still much older.
  • Weapon of Choice: A paintball gun. Or his old service revolver. That works, too.
  • You Look Familiar: Cribbins co-starred in Daleks – Invasion Earth: 2150 A.D. in 1966. Sure, it isn't canon, but nonetheless.

Professor River Song (aka Melody Pond)

 Spoilers!

 Played by: Alex Kingston (2008, 2010-2016), Sydney Wade, Harrison/Madison Mortimer, Maya Glace-Green, Nina Toussaint-White (2011)
—Travelled with the Tenth, Eleventh, and Twelfth Doctors, in that order from her perspective

A professor of archaeology who has an unusually close relationship with the Doctor. She and the Doctor never meet in the right order; the Tenth Doctor first met her in the Library in the 51st century, where it would be the last time for her, and it only gets more confusing from there. They move roughly in opposite time directions, and depending on what end of the timeline they're on respectively, they each know secrets about each other that they're unable to talk about without creating paradoxes. As a result, she's a walking collection of "Spoilers!" and very much aware of it.

  • Adventurer Archaeologist
  • Adventurer Outfit
  • Always a Bigger Fish: Shortly after "killing" the Doctor, she ran across an irate Missy who felt cheated out of her ultimate victory. Poor River found out how dangerous the Master can be.
  • Anti-Hero
  • Ax Crazy: Extremely so in "Let's Kill Hitler", as her young, Doctor-wanting-to-kill incarnation as Mels.
  • Badass: She made a Dalek ask for mercy. A freakin' Dalek!
  • Badass Boast: In "The timeline of River Song" which was in Doctor Who confidential after the 2011 finale, during the footage of River effortlessly gunning down multiple Silence with a laser pistol from the start of the series.

  Did I mention I was kick ass with a gun? No one kidnaps me and gets away with it!

  • Badass Bookworm: Scariest Archaeologist Ever. She is rather kickass for an academic.
  • Battle Couple: The Doctor and River Song are made of this. He is feared across time and space, and she is part-Time Lord and raised as a weapon to fight the Doctor. They've fought off alien invaders back-to-back, while flirting.
  • The Big Guy: She is the most competent fighter out of the Eleventh Doctor's companions, other than Rory when he taps into his memories of his time as the Centurion.
    • The Smart Guy: She is arguably even more intelligent then she is strong, so she probably fits this better in the team lineup, with Rory as The Big Guy.
  • Bi the Way: Word Of Moffat. In her first episode, she had one team member keep on his helmet because he was the only person in the room she wasn't attracted to. The room consisted of Donna and the Doctor, two female members of her archaeology crew and the two Daves.
  • Black Best Friend: In her youth to Amy and Rory.
  • Buxom Is Better: Has cleavage that could "fell an ox." In her last appearance, she catches the Halassi Androvar in this ample bosom.
  • Boxed Crook: In The Time of Angels/Flesh And Stone. Her crime is "killing the best man [she] ever knew". The man turns out to be the Doctor, of course, although his death was faked.
  • Brains and Bondage: The trope's poster girl for the series. Why would she have handcuffs? Spoilers.
  • Brainwashed and Crazy: Spends the first years of her life being indoctrinated to kill the Doctor. Does so, then realises that she's made a horrible mistake, revives him using her regeneration energy and spends the rest of her life trying to make up for it.
  • Catch Phrase: Along with "Hello, sweetie!" whenever she meets the Doctor, she also says "spoilers" when keeping anyone's relative future a secret. It's also her Famous Last Words before her Heroic Sacrifice.
  • Character Development: Played With, a lot. When we first meet her, she's very mature and independent, but we don't know anything about her yet. Since her life unfolds in the opposite direction of the Doctor's, we very slowly get to know her, but each time we see her she's a bit younger. Eventually, when we see who she really is and how she became River Song, she's very young, barely out of puberty, and incredibly crass and stupid.
  • Child Soldiers: Raised by the Silence to kill the Doctor for the first few years of her life.
  • Clingy Jealous Girl: Subverted. While a bit put out that the Eleventh Doctor never clarified the nature of their relationship to Clara, she understands that that's who he is and is perfectly helpful and considerate towards Clara. Helps that she's technically dead when they meet and is essentially giving the Doctor her blessing to move on with another woman.
  • Consummate Liar: So as to not spoil anyone's relative future.

 "I lied. I'm always lying."

  • Earn Your Happy Ending: A night on Derilium lasts 24 years affording a real happy ending with the Doctor.
  • Extreme Omnisexual: Once dated a guy made of plastic.
  • Expy: Steven Moffat says she's partially based on Indiana Jones.
  • Failed a Spot Check: Twelve drops heavy hints that he's the Doctor but she misses them all until the end of the episode.
  • Family Relationship Switcheroo: Inverted. Typically the situation is that a child is raised by someone they're told are not their mother or father but secretly are. River spent her childhood with her parents without them knowing it was her, though she knew. And due to Trolling Creator, just as we're starting to figure all of that out, there are anvil-sized hints that Amy's baby may also be the Doctor's. It turns out to be a giant Red Herring.
  • Faux Affably Evil: In "Let's Kill Hitler", prior to her Heel Face Turn. She acts much like she always does, except with more murder attempts.
  • Femme Fatale: Becomes this in her middle phase, black dress and all. Thinks she's this when she's young. Grows out of it when she's older, which is when we first meet her.
  • Foregone Conclusion: Her death in her first appearance, "Silence in the Library/Forest of the Dead". Her subsequent appearances are earlier in her timeline. She even picked up on this because the Doctor gave her a diary that would run out of pages just before the library.
  • Good Thing You Can Heal: Had the ability to regenerate but gave up her extra lives to bring the Doctor back to life. Though it's unclear how many regenerations she actually had.
  • The Gunslinger
  • Half-Human Hybrid: She's got primitive Time Lord DNA from being conceived on the TARDIS. It's explicitly said that she's the TARDIS' daughter as much as she is Amy's and Rory's.
  • Half-Identifying Hybrid: A complicated version. She always claims to be human, given the reputation of Time Lords in the new series, but she acts in a manner perfectly befitting a renegade Time Lords.
  • Happily Married: To the Doctor, although most of her meetings after the marriage, he hasn't married her yet, and he doesn't realize he's going to -- although he starts to suspect it as soon as the topic comes up.
  • Have We Met Yet?: The Doctor and River meet in the wrong order: for example, the Doctor's first encounter with her is her last encounter with him. In her first encounter with him, she realizes he's already had many encounters with her future self, motivating her to save his life.
    • In "A Good Man Goes to War", Rory asks River this when he comes to recruit her to find Amy.
  • Heel Face Turn: Kills the Doctor, then brings him back to life, using up all her remaining regenerations in the process. "As first dates go, I'd say that was mixed signals."
  • Heroic Sacrifice: Twice. Both times to save the Doctor's life. The first time (from her perspective), she tries to kill him, then uses all of her regeneration power all at once in order to save him. The second time (from her perspective), she prevents him from making a Heroic Sacrifice to save Donna and thousands of others, and gives her own life to save him instead. She had to, because she wouldn't even exist if he'd died that day.
  • Hypercompetent Sidekick: She can fly the TARDIS better than the Doctor, amongst other things. Extremely justified: The TARDIS is her second mom.
  • Hypocrite: Doesn't like the Doctor having other spouses. Doesn't stop her from having other spouses.
  • I Know Your True Name: The only non-Time Lord character in the show's history confirmed[1] to know the Doctor's real name. For a very good reason.

Tenth Doctor: River, you know my name. You whispered my name in my ear. There's only one reason I would ever tell anyone my name -- there's only one time I could.

  • Improbable Aiming Skills: Shooting Eleven's stetson right off his head.
  • In Love with the Mark: River was supposed to be the Silence's weapon to use against the Doctor. She learned another side of the story while growing up with Amy and Rory and fantasizes about marrying him instead. She still tries to kill him, but saves his life when she realises the implications. When it came time to kill him at Lake Silencio, she refused, and all of time nearly fell apart due to it being a fixed point in time.
  • Insecure Love Interest: In her final appearance, she states her belief that the Doctor doesn't love her nearly as much as she loves him. While this does seem to be the case, it doesn't mean that he doesn't love her.
  • Instant Expert: In TARDIS piloting. Justified, since the TARDIS herself teaches her via telepathy, and is her second mom.
  • Internal Homage: A nod to the extremely long-running Expanded Universe companion Bernice Summerfield, another professor of archaeology who keeps a diary about the Doctor.
  • Karma Houdini: Played straight and possibly subverted. After nearly tearing the universe apart during the Season 6 finale, claiming that her suffering will outweigh that of everyone else in the universe, the most she gets is a What the Hell, Hero? speech from the Doctor and a largely voluntary stay inside a Cardboard Prison. Possibly subverted in that they keep running into each other backwards, which means that eventually, the Doctor won't know her, but whether it's invoked as an actual punishment or simple coincidence is unclear.
  • Kid From the Future: She's Amy and Rory's daughter.
  • Kiss of Death: She prefers hallucinogenic lipstick over the traditional poisonous lipstick. Played straight in "Let's Kill Hitler", when she was programmed from birth to assassinate the Doctor.
  • Lady of Adventure
  • Large Ham: In "The Time of Angels" and especially "Let's Kill Hitler", when she's still very young.
  • Laser Guided Tykebomb: She was originally raised as a weapon to kill the Doctor.
  • Like an Old Married Couple: Her bickering with the Doctor is made of this.
  • Like Mother, Like Daughter: She has a penchant for denying mercy to her enemies even when they beg for it, and she's willing to tear time itself apart for her husband's sake. Just like her mum, it turns out.
  • Loony Fan: Was deliberately brought up all her life to become obsessed with the Doctor, and inevitably fell in love with him in the process. Sacrificed centuries of her life to save him. Then studied archaeology just so she could find him again. When they finally meet face-to-face again years later, she firmly believes that if she were to be separated from him again, she would suffer more than the rest of the universe combined. When he hears her say that, the Doctor marries her in sheer exasperation, just to get her to listen. From that point on, though, she becomes much more mature, and he's in no way inclined to divorce her.
  • Love Confession: River professes her love to the Doctor in "The Wedding Of River Song."
  • Lovable Sex Maniac: Although the Doctor is the only one we know she is sleeping with.
  • Luke, I Am Your Father / Luke, You Are My Father: River is Melody Pond, the daughter of Amy Pond and Rory Williams. River tells them this after her newborn self is kidnapped.
  • The Masochism Tango: The first time she properly meets the Doctor, she tries to kill him with poison lipstick, then makes a Heroic Sacrifice to revive him. The second time she properly meets the Doctor, he angrily makes her marry him (long story) and they snark at each other as time itself explodes around them. From that point on, they date quite happily, but she gets on significantly less well with younger versions of him that she occasionally meets -- because she can't spoil anything for fear of paradox. By the time she meets a version of him so young that all they can have is UST, their entire relationship revolves around snarking, bitching and flirting while he keeps on being frustrated at how secretive she is. The last time she meets him, she punches him in the face, handcuffs him to a wall and makes a Heroic Sacrifice to save his life.
  • Mrs. Robinson: The Doctor calls her this. She's not amused.

Doctor: ...the Legs, the Nose, and Mrs. Robinson.

River: I hate you.

Doctor: No, you don't!

    • In her past (and his future), though, she gleefully calls him "Benjamin" in return.
  • The Nth Doctor: Alex Kingston, Harrison and Madison Mortimer, Sydney Wade, Maya Glace-Green and Nina Toussaint-White. Technically, some of those actresses are differently-aged versions of the same regenerations, but still.
  • Poisonous Friend
  • Psychopathic Womanchild: In "Let's Kill Hitler" she's essentially a hyperactive teenage girl in a 40-year-old body. One who sees nothing wrong with firing a lot of guns to get her way.
  • Really Seven Hundred Years Old: She's older than 224 when she dies, having inherited the Time Lord lifespan.
  • The Reveal: River Song is in fact Melody Pond, the daughter of Amy Pond, Rory Williams and the TARDIS. She's also been one of Amy and Rory's closest friends since long before they saw her fly out of the Byzantium or take over the Auton Roman camp.
  • Running Gag: She seems to have a habit of shooting whatever hats the Eleventh Doctor finds himself wearing.
    • And free-falling and being caught by the TARDIS.
  • Sassy Black Woman: As Mels.
  • Shipper on Deck: Ships Amy and Rory, her parents, and merrily played a part in them hooking up when they were all teenagers. Although they most likely would have, anyway.
  • Sociopathic Hero: She has shades of this, and it's played very darkly in the series six finale.
  • Stable Time Loop:
    • She's named after herself... twice. To explain, Amy named her "Melody" after her childhood friend, Mels... who turns out to ''be'' her daughter Melody. The second time, she adopts her Gamma Forest name translation "River Song" only because the Doctor, Amy, and Rory keep calling her that, because that's the name they always knew her by.
    • Gets the idea of defacing land marks to summon the Doctor from Amy and Rory, who in turn got it from her.
    • She and the Doctor give each other the "Spoilers!" Catch Phrase, during their respective first proper meetings.
  • Strong Family Resemblance: Her first incarnation really resembles her mother, Amy Pond.
  • Suddenly Ethnicity: Played With, subverted, then Played Straight, then completely turned on its head again. Is half human, half Time Lord. Except that she has no Time Lord parents -- her parents are two humans and the TARDIS. And she spent her entire childhood in her second regeneration, which happened to be black.
  • Super Strength: A very minor example, but in "Day of the Moon" River mentions that the little girl -— her younger self, it turns out -- would have to be incredibly strong to tear herself free from the space suit.
  • This Is My Name on Foreign: Played for a dramatic reveal in "A Good Man Goes to War", when it turns out that River Song's name is actually a close in the language of the Forest People: "Melody" becomes "Song", and they don't quite have a word that means "Pond" because "The only water in the forest is the river..."
  • Timey-Wimey Ball: Deep breath: Conceived on the TARDIS and born in Demon's Run, given the nickname "River Song" by accident. Grows up in the 1960's as Melody Pond, named after Amy's and Rory's best friend Melody. Travels to England after regenerating into a toddler, where she grows up in the 90's together with Amy and Rory as their best friend Melody. Meets the Doctor properly and tries to kill him, then does a Heel Face Turn when she realises that the "River Song" broad he's so fondly talking about is her in the future. Studies archaeology in the 52nd century. Meets the Doctor properly for the second time when she's forced to kill him, refuses until he marries her. Gets locked in Stormcage for the murder, where the Doctor, now her husband, merrily takes her on dates every once in awhile at very random points in her timeline -- all the way up to the Singing Towers, her final date with Eleven, during which he gives her his screwdriver. Also meets increasingly younger versions of him throughout that period (i.e. the regular episode order, backwards for her) until she finally meets Ten, dies, and he saves her consciousness with said screwdriver.
  • Touched by Vorlons: As a result of being conceived in and by the TARDIS, she is part-Time Lord. The Doctor tries to argue that evolution does not work that way. The TARDIS pointedly disagrees.
  • Twin Threesome Fantasy: In "A Good Man Goes to War", River strongly implies that she once spent a very enjoyable birthday with two Doctors at once.
  • Whole-Plot Reference: To one of Steven Moffat's favourite novels, The Time Travelers Wife. The similarities would take quite a while to count. She even meets the Doctor in a library, exactly like the novel's titular characters.
  • Wife Husbandry: "The Impossible Astronaut" revealed that the first time River met the Doctor he knew everything about her, and it's starting to trouble River herself. As it turns out, he knew her as an infant -- she's Melody Pond. Subverted in that the Doctor doesn't realize he knew her as a child until some time after they had their first kiss.
  • Younger Than They Look: Is a young twenty-something when she gets her adult body. She instantly loves it.
  • You Already Changed the Past / You Can't Fight Fate: The Doctor's first meeting with River is her final meeting with him, and the first time River meets the Doctor (at least at a point she can actually remember, rather than as a baby), he knows everything about her. This means they have no true beginning to their relationship (when one of them first meets the other, the other already knows and cares for the other deeply), and two endings.
    • Another example: River's assassination of the Doctor-inside-the-Teselecta is a fixed point in time. When she attempts to avert it, the universe is plunged into a massive [[Anachronism Stew]] that threatens to tear time itself apart, leading the Doctor himself to unleash a [[What the Hell, Hero?]] on her.

"The Next Doctor"/Jackson Lake

 I'm the Doctor! Simply, 'the Doctor.' The one, the only and the best!

 Played by: David Morrissey (2008)
—Travelled with the Tenth Doctor

The Doctor teams up with this Doctor during the 2008 Christmas special on Christmas Eve, 1851, making the traditional Doctor into his companion for a while. Of course, this Doctor was just a normal human, but that doesn't change how awesome he was.

Rosita

 Rosita: I'm glad you think it's so funny. You're mad! Both of ya! You could've got killed!

Jackson Lake: [still guffawing] But evidently we did not!
—Travelled with the Tenth Doctor

 Played by: Velile Tshabalala (2008)

Companion of the aforementioned other Doctor, who teams up with the both of them.

  • Badass Normal
    • Veers into Only Sane Man in the chase scene, when she's the only one with the presence of mind to cut the rope loose before both Doctors can be dragged out the window.

 Rosita: You idiots.

Lady Christina de Souza

 Tenth Doctor: Come on, Allons-y!

de Souza: Oui, mais pas si nous allons vers un cauchemar. [Yes, but not if we're going into a nightmare.]

Tenth Doctor: [Obviously impressed.] Oh, we were made for each other!

 Played by: Michelle Ryan (2009)
—Travelled with the Tenth Doctor

One-shot character during the 2009 Easter Special, Lady Christina is a thief of noble blood from the early 21st century drawn into the Doctor's world of the weird.

Captain Adelaide Brooke

 This is wrong, Doctor. The Time Lord Victorious is wrong.

 Played by: Lindsay Duncan (2009)

Young Adelaide played by: Rachel Fewell (2009)

Stepping into the companion role for "The Waters of Mars" was tough-as-nails Captain Brooke, heading the very first human Mars colony in the 2050s. The Doctor is a huge fan of her, which makes him slightly more involved and slightly less level-headed than usual -- with disastrous results.

Amelia "Amy" Pond

Amy: Twelve years! And four psychiatrists!

Eleventh Doctor: Four?

Amy: I kept biting them. They said you weren't real.

 Played by: Karen Gillan (2010-2012, 2013)

Young Amelia Pond played by: Caitlin Blackwood (2010-2011)
—Travelled with the Eleventh Doctor

Amy, a kissogram, is a Scot raised in a small village in rural England. She first met the Doctor as a little girl in 1996, an encounter that everyone but Amy dismissed as imaginary. But Amy never forgot her "raggedy Doctor", and he served as a sort of imaginary friend for her… until he finally returned, twelve years later. Her relationship with the Doctor is arguably inspired by Wendy Darling's relationship with Peter Pan.

  • Amnesiac Lover: From the end of "Cold Blood" to the end of "The Pandorica Opens". Subverted in that it's the Doctor trying to rekindle Amy's memories of Rory, who's been completely erased from existence.
    • Subverted again in "The Wedding of River Song." Amy remembers that she has a husband named Rory whom she loved dearly, but can't remember who he is, even when looking Captain Williams in the face. Again, it's the Doctor who tries to restart both their memories.
  • Aw Look She Really Does Love Him: While she often takes Rory for granted, if anything happens to him, she'll be crushed, even suicidal. "The Girl Who Waited" is one big testament to how deeply she's in love with him.

 Old!Amy: You're asking me to defy destiny, causality, the nexus of time itself for a boy.

Young!Amy: You're Amy, he's Rory... and oh yes I am.

  • Badass Normal
  • Berserk Button: Like Rory, hurt her family and you'll regret it.
  • Betty and Veronica: The Archie to Rory's Betty and the Doctor's (unwanted position as) Veronica.
  • Beware the Nice Ones: When pushed enough or her family's in danger, she can be terrifying. Her (much-deserved) murder of Madame Kovarian, for example.
  • Bi the Way: Seems to be mostly straight, but quite fancies herself.
  • Bitch in Sheep's Clothing: Because of the cracks affecting her reality so much and leaving her with a fear of abandonment even before the Doctor entered and then left her life, she treated Rory pretty badly during Series 5. She got much better once time was fixed, but she still has her moments.
  • Broken Bird/Break the Cutie: The Doctor abandons her repeatedly in "The Eleventh Hour", leaving her with lifelong psychological problems as a result.
    • She repeatedly suffers this in "A Good Man Goes to War": First she gives birth in captivity, held prisoner God-knows-where in time and space. Then her baby girl is taken away from her by the villains. Then after [[Hope Spot|the sheer joy of getting Melody back and reuniting with her husband and the Doctor]], the villains reveal that they've already taken off with the baby and replaced her with a flesh duplicate, which promptly dissolves in Amy's arms.
    • In "The Girl Who Waited", she's left to fend for herself against killer robots for 36 years, hardening her into a bitter old woman whose faith in the Doctor has dissolved into hatred.
    • Finally, in "The God Complex", the Doctor deliberately breaks that faith in order to save both her life and her future.
  • The Call Put Me on Hold: As above, she answered yes to the call long before she was able to actually have the adventure associated.
  • Clingy Jealous Girl: She gets pretty annoyed when she thinks Rory is more focused on another woman. Justified for a few reasons though; he's her husband, he's had a Single-Target Sexuality on her for most of their whole lives, he has a tendency to die and she's feeling quite guilty over calling him her "sort of boyfriend" in their first episode.
  • Changed My Miniskirt: A worse offender than the Doctor himself. Wearing a miniskirt in public probably would have been a hanging offence in 16th century Venice, and that's just one example.
  • Character Development: In Series 5, she could never give up being with the Doctor. In Series 7, she gives up seeing the Doctor ever again so she can be with Rory.
  • Character Tic: In Series 5, she would bulge her eyes and pucker her mouth a lot. As she never does it in Series 6, this was probably intentional on Karen Gillan's part.
  • Double Consciousness: After the events of "The Big Bang", she remembers two different versions of her life, as stated in the "Good Night" mini-episode. In "The Wedding of River Song", this is now triple consciousness, with Amy remembering her life in the time-everywhere universe.
  • Double Standard Abuse (Female on Male): Indulged in this a bit in Series 5, verbally beating Rory over the head on more than one occasion.
  • Drives Like Crazy: According to Rory. She only passed her driving test by invoking Ms. Fanservice.
  • Fag Hag: Believed herself to be this to Rory for years. It's implied they hooked up as soon as she realized she wasn't.
  • Fiery Redhead: Though she mellows out considerably as time goes on.
  • Friends with Benefits: Wants to be with with the Doctor. She gets one kiss in before he pushes her away. She tries again during her wedding -- twice.
  • Future Badass: Thirty six years spent defending herself from robots who kill with kindness. With a sword.
  • Grandma, What Massive Hotness You Have! / Never Mess with Granny: Since Older Amy is something like 58 years old, quite justified.
  • Genre Savvy: She doesn't quite match Rory, but there are numerous examples, most notably the fact that it only takes her three very brief encounters with the Silents to figure out that they have some kind of agenda against the Doctor, what powers they have, and that it would probably be wise to take a cellphone photo of one.
  • Heroes Want Redheads: Inverted with the Doctor, played straight with Rory.
    • In the 2011 Comic Relief short, Amy Pond flirts with herself.
  • Hidden Depths: She really loves van Gogh's work.
  • Hot Chick with a Sword: In "The Girl Who Waited".
  • Hot Mum
  • I Choose to Stay: More accurately, I choose to be sent back to 1930s New York to be with Rory.
  • In-Series Nickname: The Girl Who Waited. Twice.
  • Jumped At the Call: Asked to come along, as a girl; unfortunately, the caller got waylaid and she had to wait for fourteen years before she got to see the inside of the TARDIS.

 Amy:When I was a little girl, I dreamed of time and space. Last night, all my dreams came true.

  Doctor: Amelia Pond! Get your coat!

  • Lady of War: In "The Girl Who Waited" the future Amy has taken a level in badass and become one of these. This attitude is also very much in evidence in "The Wedding of River Song".
  • Laser-Guided Amnesia: Done to her memories of Rory courtesy of the time-crack. And, it later turns out, to her memories of her parents as well.
  • Last-Name Basis: The Doctor has the habit of calling her “Pond.“
  • Like Brother and Sister: Appears that way with Rory in series 5; they get mistaken for siblings in The Vampires of Venice.
  • Limited Wardrobe: For the first six episodes of the 2011 series, appeared to have nothing in her wardrobe except two or three similar-looking plaid shirts. Possibly a subliminal hint to the audience that she's actually a mind-linked Doppelgänger in these episodes.
  • Love Triangle: Thinks she's in one with Rory and the Doctor. Rory and the Doctor both disagree. She readily accepts the fact that the Doctor wouldn't necessarily love her, being a 907-year-old alien and all, but she still hopes for a quick shag. The Ship Tease around it eventually becomes a major plot point, due to Trolling Creator, when she becomes pregnant and people start to assume that it might be the Doctor's baby. Of course, it's not -- despite there being, at first, overwhelming evidence for it.
  • Mama Bear: Very nearly kills a spaceship full of people, including herself and Rory, to save their child. No guarantee that anyone died, but none that everyone lived, either.
  • Meet Cute: She and the Doctor have one when he shows up in a crashed TARDIS asking for an apple.
  • Mistress Of The Mixed Message: Towards Rory in Series 5 and early in Series 6. Since then, she's clearly established him as her number one priority.
  • Ms. Fanservice: She's a Kissogram, and so has several… interesting outfits. Seen onscreen is a Fair Cop police uniform; refered to are Naughty Nurse Outfits, Naughty Nun, and French Maid outfits. Has a general liking for short skirts or hotpants that show off Karen Gillan's long legs; there's only two episodes of the fifth series in which we don't see her in something like that.
  • Oblivious to Love: For a kissogram, she was a little bit slow in realising that Rory liked her.
  • Pajama-Clad Hero: In "The Beast Below" and "A Good Man Goes to War", although in the latter episode they're hospital pyjamas.
  • Pinball Protagonist: In "Asylum of the Daleks" where she's little more than a prop for the Doctor to interact with.
  • Reality Warper: Her Ripple-Effect-Proof Memory is the only reason the Doctor's second Big Bang goes off without a hitch and is also the only way the Doctor comes back into existence.
  • Real Life Relative: Gillan and Blackwood are cousins who had never met before being cast to play Amy.
  • Redheaded Hero
  • Ripple-Effect-Proof Memory: Develops this as an actual explicit power, though not so much ripple-proof as ripple-resistant. She can lose memories of her own history if she doesn't really concentrate when the moment is rewritten. But she can get those back. This culminates with her remembering the Doctor back into existence after a rather nasty Ret-Gone.
    • This skill comes back again in "The Wedding of River Song" — unlike Rory, she can remember events in the correct timeline, but only with a lot of effort and many scribbled illustrations.
  • Scarf of Asskicking: Occasionally wears one.
  • Screw Yourself: When the TARDIS gets split in two, Amy finds her duplicate self rather fetching.

Doctor: Ohhh... this is how it all ends. Pond flirting with herself -- true love at last. Oh, sorry, Rory.

Rory: Absolutely no problem at all.

  • Security Cling: The Eleventh Doctor and Amy have a variation. Because Amy's story is one traumatic Break the Cutie moment after another, the Doctor develops a habit of clinging tightly to her and rubbing her back while delivering each new piece of bad news. Asking permission from her husband Rory every time, of course.
  • She's Got Legs: To the point where "Time" seemed to be about them. Clara even later says that Amy was "made of legs."
  • Ship Tease: With the Doctor. This becomes a major plot point when she becomes pregnant and her baby has Time Lord DNA. Due to Trolling Creator, it takes a while before we find out that it was all a big Red Herring, and the Doctor really has never touched Amy.
  • Shipper on Deck: Per word of Karen Gillan, in "Asylum of the Daleks", Amy very quickly jumped aboard the Doctor/Oswin ship, loving that the Doctor found a girl who could match his Motor Mouth and constantly took him down a few pegs.
  • Show Some Leg: How she got her driver's permit.
  • Small Name, Big Ego: Very mild case of this sometimes, as she tends to overestimate her own competence.
  • Strange Girl: Amy's insistence that her childhood encounter with the Doctor was real is apparently well-known to the people in her small town… and has landed her in psychiatric care a few times. This makes her the first companion with canonical mental issues since Ace.
    • She has distinct and serious obsessive tendencies, seems to suffer severe sensory overload on occasion, and at one point in "The Beast Below" (although this is almost certainly unintentional) her speech patterns are disturbingly similar to Ladd Russo's. The implication is that these obsessive tendencies have been focused mainly on the Doctor during the twelve years they've spent apart.
    • She also shows a reluctance to face growing up, or at least getting married. Hardly surprising, given the aforementioned Peter Pan parallels.
  • Surprise Pregnancy: Because the audience didn't know about it until she was ready to give birth.
  • Took a Level In Badass: Thirty-six years of defending yourself from killer robots will do this.
  • Tranquil Fury: Has an almost terrifyingly dark moment when she confronts Madame Kovarian and pretty much leaves her to be killed by the Silence, after everything that the woman has put her through. You can seriously tell that she's frothing with rage but she doesn't raise her voice at all.
  • Trauma Conga Line: Gets severely traumatised roughly every two episodes. In "Night And The Doctor", she tries to talk to the Doctor about it, but he sort of dodges the implications of all that's happened to her.
  • Tsundere: "Harsh" type at the beginning of Series 5, "sweet" by the end.
  • Violently Protective Wife: It's not a good idea to mess with Rory.
  • Wistful Amnesia: Finds herself crying over Rory without realizing it or knowing why several times in series 5.
  • Yaoi Fangirl: As shown in the comics, when Rory kisses the Doctor by accident and Amy asks them to do it again. Slower.
  • You Called Me "X" - It Must Be Serious: As she points out, the Doctor only calls her "Amelia" when he's worried about her. And "Amy Williams" when things get very, very serious.
  • You Have Waited Long Enough: Amy runs off with the Doctor on the night before her wedding.
  • You Look Familiar: Karen Gillan had previously played a soothsayer in a Tenth Doctor episode, "The Fires of Pompeii".

Rory Williams

 Moffat: "Rory Pond is everything I could never be — brave enough to show when he’s scared, man enough to take his wife’s name, and so steadfastly in love that he’ll wait 2,000 years and not complain once. Everyone needs a Rory in their life."

 Played by: Arthur Darvill (2010-2012)

Young Rory played by: Ezekiel Wigglesworth (2011)
—Travelled with the Eleventh Doctor

Rory is a nurse, Amy's childhood friend, and now her husband. Started off as incredibly reluctant to travel with the Doctor, out of love for Amy and fear for his own life. Eventually rose to the challenge and became a force to be reckoned with.

  • Amnesiac Lover: In "The Wedding of River Song", in which he's lost all his memories of the correct timeline and only knows Amy as his boss. The Doctor tries to get them back together again… and fails. At first.
  • Atheism: The Doctor explicitly points out that he doesn't get affected by an alien that feeds on faith because he doesn't really believe in anything.
  • The Atoner: As an Auton, following the death of Amy by his own hands.
  • Back From the Dead: Or back from the Ret-Gone.
  • Badass Normal
  • Badass Adorkable: "A Good Man Goes To War" has him terrifying Cybermen and then later crying with joy at his baby daughter.
  • Betty and Veronica: The Betty to Amy's Archie and the Doctor's (unwanted position as) Veronica.
  • Berserk Button: Never mess with Amy or his baby.
  • Beware the Nice Ones: Normally a gentle soul (he's a nurse, after all), but press his Berserk Button and you will regret it.
  • Butt Monkey: Toned down a lot since he became the Last Centurion, but he still gets this treatment now and then.
  • The Casanova: Seems to attract a myriad of female admirers.
  • Character Development: He went from an insecure Mickey-type character whose main purpose was to look hurt, to a Badass Adorkable man who is willing to spend two thousand years protecting his wife.
  • The Champion: Spent 2000 years as the Guardian of the Pandorica, simply to make sure Amy would remain protected.
  • Cleopatra Nose: Which the Doctor can't resist ribbing him about.
  • Colonel Badass: Starts to give off these vibes in "A Good Man Goes to War", then fully grows into the role in "The Wedding of River Song".
  • Covert Pervert: In Space and Time he accidentally causes a major malfunction in the TARDIS because of A. His wife is wearing a skirt and B. The TARDIS has a glass floor.
  • Deadpan Snarker
  • Determinator: Auton!Rory spent 1894 years protecting the Pandorica simply because Amy was inside.
    • In "The Wedding of River Song", in another version of reality, to give Amy time to flee, he ignores the fact he's being electrocuted in his eye.

 Amy: You have to take your eye-drive off!

Rory: I can't do that ma'am, I can't forget what's coming.

Amy: But it could activate at any moment!

Rory: It has activated, ma'am.

  • Distressed Dude: Frequently. Amy never takes it well.
  • Double Consciousness: Rory remembers both his original life and his life as the Last Centurion in the universe of the Total Event Collapse. However, he's worked out how to block away the latter set of memories most of the time — unless he decides he needs to access them.
  • The Dreaded: The Last Centurion.
  • Fan Service Pack: Mild version. In Series 6, the costume department gave the character more flattering clothes (like tighter jeans) and hair gel. Also applied to the roman uniform when it reappears.
  • The Fettered: Remembering his time as The Centurion hurts, so he blocks it out for his own sanity. When needs must he has has 2,000 years of experience as well as years of training as a Roman soldier that he can draw on.
  • Foil:
    • The Nurse to the Doctor's Doctor.
    • To Amy. She wants to go around the universe being special while Rory is content just being a normal guy.
  • Genre Savvy: Rory knows a bit about science and science fiction, and the Doctor gets peeved when Rory doesn't need anything explained to him, especially how he perfectly understands the TARDIS interior being bigger on the inside.
    • When we're first introduced to the character, he notices — and photographs — coma patients walking about while everyone else is distracted by the sun going wibbly. Doing so helps the Doctor reveal the location of Prisoner Zero to the Atraxi, saving the world from incineration.
  • The Good Captain: In The Wedding of River Song.
  • Good Looking Privates: The writers really do seem to like putting him in uniform, just about any uniform, really. Security guard, modern combat fatigues, and particularly his signature Roman centurion outfit.
  • Guile Hero: Rory definitely fell into this mold over time, to the point where in "Let's Kill Hitler";

 Amy: Can you even ride a motorbike?

Rory: Dunno. Expect so. It's that sort of day...

 Amy: Would I make it up at a time like this?!

Rory: Well, you do have a history of [receives Death Glare]… being very lovely.

  • Heroic Bystander: Though not a fan of adventuring, Rory sets the tone early when, upon coming across a vampire attack, his first impulse is not to flee or chase the monster, but to stop the victim from bleeding to death. Throughout his time with the Doctor, he tends to act to save life first and foremost. This leads to him not only tending the wounded, but frequently doing awesome things like punching Hitler out to stop him shooting an apparent innocent bystander, and then locking him in a closet!
  • Heroic Willpower: In his Auton form as the Centurion. He draws on this again in "The Wedding of River Song," but it nearly fails. Despite this he manages to keep his gun aimed through nigh unbearable pain. Rory gives Samuel L. Jackson a run for his money in BAMF territory.
  • Hero of Another Story: Early in "The Big Bang", he spent 1894 years worth of history guarding the Pandorica. Probability of zany adventures: extremely high.
  • I Just Want to Be Normal: Rory's ideal world as recreated by the Dream Lord is rather quiet — he is a doctor instead of a nurse, Amy is pregnant, and most of the residents of their hometown are over 90.
  • In-Series Nickname: The Last Centurion.
  • It Got Worse: Story of his companionship and non-existence right up through the penultimate episode of Series 5, which culminates in an Auton with his memories killing Amy against Rory's will.
  • Just Friends: Type 2. Had feelings for Amy whilst she was Oblivious to Love to the point she thought he was gay.
  • Knight in Sour Armor: Starts to display shades of this in Series 6, thanks to spending 1,894 years straight guarding the Pandorica from anything and everything that could possibly threaten it. In "The God Complex" he reveals that he neither fears nor believes in anything anymore.
    • This has the unexpected bonus of making Rory highly resistant to Mind Rape, if "The Doctor's Wife" and "The God Complex" are any indication.
  • Love Martyr: Has elements of it in the cracked timeline. After he dream-dies in "Amy's Choice", Amy admits to the Doctor that she never told him she loved him. And this was the (constant) day before their wedding.
  • The Medic: Rory is a nurse, and acts like it. (See Heroic Bystander above.) As of "A Good Man Goes to War" he's evolved into Combat Medic.
  • Mistaken for Gay: Amy never saw him show any attraction to any girl, and assumed this. Except she was being too thick to realise that there was at least one he liked…
  • Nice Guy
  • Noodle Incident: He spent 1894 years staying out of trouble… unsuccessfully.
  • Not So Different: To the Doctor. Best shown in "A Good Man Goes To War", where his actions demonstrate that episodes title could be interpreted as referring to either the Doctor or himself.
  • Older Sidekick: Has nearly 2,000 years worth of memories in his head, giving him a longer lifespan than the Doctor when they were travelling together.
  • One-Man Army: Successfully served as Guardian of the Pandorica for 2000 years.
    • Best demonstrated in "A Good Man Goes To War", where Rory, in full Centurion gear and armed only with a sword, managed to waltz through a Cyberman-controlled vessel and scare the living crap out of them. He also fights off an army of Headless Monks with a sword and ray gun (granted he had help, but still it's pretty awesome).
  • Papa Wolf: Where. Is. My. Wife.
  • Phrase Catcher: Manages to get a good "Oh, Rory" out of the Doctor every once and awhile.
  • Pinball Protagonist: In "Asylum of the Daleks" where he's little more than a prop for Oswin to move around.
  • Promotion to Opening Titles: As of the 2010 Christmas special, and thereafter.
  • Puppy Dog Eyes: They can rival the Tenth Doctor's.
  • Really Seven Hundred Years Old: Mentally, he's almost two thousand years old, older than the Doctor was during their time together.
  • Ret-Gone: Temporarily; he's not only fatally shot, but absorbed by one of the cracks afterwards. The Doctor remembers him, but Amy doesn't.
  • Secret Test of Character: The Doctor intentionally pushes his Berserk Button (see above) to see if the Auton-Rory he's talking to has genuine human emotions. He does.
  • Seen It All: By the time of late Series 6, nothing surprises him anymore. He even (correctly) assumes that he'll just be able to ride a motorbike with no appropriate explanation.
  • Shrouded in Myth: In his Auton form as the Centurion, getting written into legends all over the world as a result.
  • Single-Target Sexuality: Only ever shows attraction to Amy. His entire life, just Amy. Which, of course, leads to Mistaken for Gay. By Amy. It's very funny.
    • In a very sweet comic in Doctor Who Magazine, Amy and the Doctor get body-swapped. Rory decides that he doesn't even care. He kisses the Doctor, realizing a bit too late that the body switch has already been corrected again. (Amy asks them to do it again. Slower.)
  • The Slow Path: As the Centurion, he spent 1894 years waiting while the Doctor skipped ahead with the Vortex Manipulator.
  • Smarter Than You Look: In his first episode, while the rest of the planet pays attention to the sun going wobbly, Rory (who up til now has just been an easily cowed nurse) pays attention to the coma patient that's out walking his dog. Later on, he figures out why the TARDIS is bigger on the inside remarkably quickly and without any help from the Doctor at all.
    • Done rather subtly throughout series 5 and 6, and tied to his Took a Level In Badass. He already was smart enough to spot Prisoner Zero, but when the Doctor comes back for him a few episodes later, he's studied up on enough physics and time travel to know more than most comparable companions. Add in his years as the Centurion and he's become one of the Doctor's most competent companions in a while. For all of his occasional mocking, the Doctor seems to trust him more than any other companion, probably due to their similar experiences.
  • Straight Man: Comes with the savvyness. Word of God says that Rory has to make himself this, otherwise he'll get sucked in to the life like Amy.
  • Submissive Badass: He is no doubt a BAMF, but he'll always be a dork and Amy will always be the one in charge.
  • Super Strength: In his Auton form as the Centurion.
  • Taking the Bullet: At the end of "Cold Blood"... and ''then'' he gets retconned out of existence.
  • Thousand-Yard Stare: The Doctor notes he has one whenever he remembers the 2000 years as The Last Centurion.
  • Tomato in the Mirror: In "The Big Bang", he was a Nestene replicant whose programming killed Amy. He got better.
  • Took a Level In Badass: At least 20 levels after his resurrection into an Auton and nearly 2000 years as the Lone Centurion. The man really would do anything for his wife.
  • Too Spicy for Yog-Sothoth: In The God Complex, the titular Hell Hotel shows people their worst fears so the Minotaur can feed on their faith. Rory has neither fear nor faith, so all it can do is show him the exit.
  • Trauma Conga Line: Part of what causes the above Character Development.
  • Undying Loyalty: To Amy.
  • Unfazed Everyman: Barely reacts to the TARDIS being Bigger on the Inside.
  • Victorious Childhood Friend
  • Vitriolic Best Buds: With the Doctor. Both the Doctor and Rory seem to enjoy the level of snark they throw at each other.

 Older Amy: That's the one.

  • Yank the Dog's Chain: Just as Amy remembers who he is… the Auton programming overruns him and he's forced to shoot her.

Craig Owens

 Has anyone ever told you that you're a bit weird?

 Played by: James Corden (2010-11)
—Travelled with the Eleventh Doctor

Rented a room out to the Doctor when the latter was stranded on Earth by a malfunctioning TARDIS. Hilarity ensued. As a result of a hasty Mind Meld Info Dump, he knows more about the Doctor's general history than most non-companion characters, and the Doctor has come to view him as a very good friend.

Clara Oswald

A nanny (later school teacher) from Earth that the Eleventh Doctor first meets as a Dalek in the future... then a Victorian governess... then as an ordinary 21st century girl. Arguably the most important companion in the history of the show and the fictional universe.

"Run you clever boy. And remember me."

Played by: Jenna Coleman (2012-2015, 2017)
—Travelled with the Eleventh and Twelfth Doctors
  • The Ace: Unlike most companions, she fit into the Doctor's role flawlessly. The Twelfth Doctor (when it looks like he's about to die) says that she was the best and made an excellent Doctor.
  • Action Girl
  • Anchored Ship: Word of God is that she's the Doctor's soulmate.
  • And I Must Scream: Oswin Oswald is a Dalek who's convinced herself that she's still human because she just can't cope with the horror of what's happened to her.
  • Anticlimax: The Doctor was convinced that she was some great cosmic force but all she was was an ordinary girl who did something nice for A Friend in Need.
  • Arch Enemy: To the Great Intelligence and Missy.
  • Attack of the 50 Foot Whatever: When possessed by Kali, Clara becomes about fifteen to twenty feet tall. She later says it was kinda fun to be a giantess.
  • Badass Normal: Clara wasn't any different from a normal human girl when she started and yet became the most important person in the Doctor's lives.
  • Baby Got Back: Eleven twice slaps her butt in a playful manner and several of the outfits she wears emphasize its large size and curvy shape.
  • Belligerent Sexual Tension: With the Doctor. No one would deny their affections but they love rilling each other up, with Clara often treating him like a total idiot who couldn't function without her.
  • Beyond the Impossible: Well she is called the "Impossible Girl".
  • Bi the Way: In addition to much Ship Tease with the Doctor, she mentions making out with Jane Austen.
  • Brainy Brunette:
    • Oswin Oswald was smart enough that the Daleks decided that she was worth sparing.
    • Clara wasn't one at first but after being uploaded, she got all sorts of knowledge "spliced" into her.
  • Butt Monkey: Whenever her personality flaws come up.
  • Character Development: She starts off as a shy shut-in before eventually becoming the Doctor's Distaff Counterpart.
  • Clingy Jealous Girl: Downplayed compared to most examples of this trope but when Elizabeth I's kissing of the Tenth Doctor goes on for longer and longer, Clara's face goes from amused to "hands off the merchandise" in very short time.
  • Control Freak: Fully admits to being one.
  • Covert Pervert: She fantasizes about pornography she's previously watched and her Victorian self tricks the Doctor to climb the ladder first so she can watch his arse as he does so. When she meets the Tenth Doctor, she all but devours him.
  • Deadpan Snarker
  • Distaff Counterpart: Evolves into the Doctor's. She even gets her own TARDIS with a broken Chameleon Circuit.
  • Earn Your Happy Ending: Though she will die eventually, she gets God knows how many years in between one second and the next having adventures in all of time and space.
  • Everyone Has Standards: Though she doesn't want to die and has an ego, she sees the lengths the Twelfth Doctor is going to overwrite her death and convinces him to stop.
  • Expy: As she developed, quite a few people began comparing her to a 21st century version of Sarah Jane Smith.
  • Foil:
    • To Rose Tyler. Both are ordinary 21st century girls who want to stay with the Doctor forever and have a romantic infuriation with him. The difference is Clara is fully aware that staying with the Doctor is an impossibility and is very conscious of the fact that she (and all the other companions) are nothing but a long line of Replacement Goldfishes while Rose will always try to be with him and loathes the idea of the Doctor having other female friends. Following Eleven's regeneration into Twelve, Clara is comfortable with any Doctor while Rose only feels comfortable around Nine or Ten.
    • For how much she and the Doctor have in common, they have two notable differences. The Doctor is one being stretched out across space/time with different faces while the Clara echoes are, broadly, the same person in different time zones with the same face. Clara loves being in control while the Doctor doesn't like authority figures.
  • Forgotten First Meeting:
    • Met the Eleventh Doctor when she was very young at a playground but never gave any indication that she remembered this.
    • She later met the First Doctor as a child but managed to convince him that it was All Just a Dream.
  • Friendly Enemy: Not quite to the Doctor's extent, but she gets along well enough with Missy. According to Jenna Coleman, Clara likes Missy even though she knows that she really shouldn't.
  • Go Mad From the Isolation: Eleven, Amy, and Rory suspect that this happened to Oswin Oswald.
  • Gotta Catch Them All: As Jenna Coleman constantly corrects people on, Clara has met all the Doctors. And if an echo didn't meet them, then she'll track down that incarnation.
  • Grand Theft Me: By Kali. It doesn't take long for Clara's willpower to force her out.
  • Green-Skinned Space Babe: Blue skin when Kali takes over.
  • Hartman Hips: Clara is one of the shortest companions (possibly the shortest in the history of the show), yet her hips are massive compared to the rest of her body. Eleven is frequently distracted by them.
  • Heroic Sacrifice:
    • Allowing herself to be shattered across history to save the Doctor. She doesn't die but she was prepared to.
    • Was prepared, in IDW's "Sky Jacks" to be at ground zero of a nuclear bomb if it meant saving the universe.
    • Tries to do this again to save Rigsy in "Face the Raven". Subverted in that Rigsy was in no real danger but Clara dies anyway. Still she was willing to give up her life to save a new father.
  • Heroic Willpower: Frequently said to have this. Nothing can deter Clara Oswald.
  • Humble Hero: Though Clara is not shy in pointing out how sexy and clever she is, never once has she asked for a reward for anything she did. It's really worth noting that she was the one, not the Moment, who convinced the Doctor to save Gallifrey and has never once, even from the Time Lords themselves, asked for any credit for this.
  • Hot Teacher
  • I Just Want to Be Normal: Unlike most companions, she wants both a normal life and a life with the Doctor. After Series 8, the normal part kind of falls apart.
  • It's All About Me: She is mentioned to have an enormous ego. "Hell Bent" ultimately shows that she's not that vain, refusing to let herself live if the universe dies as a result.
  • Jumped At the Call: Oswin and Clara Oswin do. Clara Prime doesn't at first but eventually dives right in.
  • Lady in Red: Oswin Oswald.
  • Leitmotif: Her theme eventually becomes canon after she departs. A deleted scene from Series 10 has Twelve, with an anguished look on his face, playing it, revealing he named it "I Forget."
  • The Lost Lenore: Briefly becomes this to Twelve to a level that puts Ten's mourning for Rose to shame.
  • Love Redeems: Her love gets Eleven and Twelve through their slumps.
  • Made of Iron: Absolutely nothing can leave a lasting mark on this girl. Not even falling twenty feet onto solid rock.
  • Morality Pet: As per the norm, she started out as the Doctor's newest one but around late Series 8, it became very unclear whether she or the Doctor was the other's Morality Pet. She fully embraces this role in her last episode however.
  • Motor Mouth: One that was more notable in Series 7 but died down over time.
  • Ms. Fanservice: Downplayed compared to most examples but she isn't shy about showing off skin. The plunging neckline on her dress in "Mummy on the Orient Express" is a noteworthy example.
  • Noodle Incident: Came to a date wearing a space helmet, made out with Jane Austen (and was banned from somewhere in the process), argued with Gandhi, lost her sunglasses and dignity at a two centuries long New Year's party, made out with Elizabeth I, visited Atlantis and clashed with the Fish People, and did something that banned her and the Doctor from the second most beautiful garden in the universe among others.
  • Not Afraid to Die: She doesn't want to die but she has no qualms facing it when the time comes.
  • One Head Taller: Inverted. She's shorter than both of her Doctors. Eleven in particular enjoyed teasing her about it.
  • Puppy Dog Eyes: Much to Twelve's annoyance, she's perfected these.
  • Ping-Pong Naivete: Pops up every now and then.
  • Pint-Sized Powerhouse: And keep in mind that Time Lords are tougher than humans. This girl can hit.
  • "The Reason You Suck" Speech: Outright calls the Time Lords, to their faces, monsters that are hated by everybody.
  • Replacement Goldfish: Knows that someone will come after her. Supposedly wrote The Companion's Companion to help her successor.
  • Self-Insert Fic: Her echoes are how she wants to be seen. Namely confident, assertive and flirtatious.
  • Ship Tease: Gets this with every Doctor she comes across. The novelization of "The Day of the Doctor" has all three versions of him almost competing over her.
  • Sitcom Arch Nemesis: To the TARDIS in Series 7.
  • Stable Time Loop: Eleven invited her to travel with him because he kept meeting her everywhere he went. When they went to Trenzalore, she threw herself into the Doctor's timestream, scattering herself along it, causing Eleven to realize that he was meeting her everywhere he went.
  • Too Much Alike: Eventually realizes that she and Twelve are this.
  • Too Spicy for Yog-Sothoth: People who try to mind control her or otherwise intrude on her mind usually wind up paying for their efforts.
  • Took a Level In Jerkass: In Series 9. An indication that she's spent perhaps a bit too much time with the Doctor.
  • Undying Loyalty: To the Doctor. Any incarnation of him.
  • Unresolved Sexual Tension: With both her Doctors.
  • Vague Age: Probably in her mid-30s but never outright said.
  • Vitriolic Best Buds: With the Doctor.
  • You Are Better Than You Think You Are: Her unwavering belief in this is what convinces the Doctor to try and find a way to spare Gallifrey.

Nardole

A Human Alien from the 54th century who was employed by River Song in her caper whereupon he was beheaded (though kept alive). After that, he was rebuilt by the Doctor and tasked by River Song to be the Doctor's Morality Pet when Missy is to be executed. He's taken up being the Doctor's overseer, a job about as easy as it sounds.

"I am empowered to kick. Your [the Doctor]. Arse."

Played by: Matt Lucas (2015-2017)
—Travelled with the Twelfth Doctor
  • Ascended Extra: He was only supposed to appear once in "The Husbands of River Song" but he got so popular he appeared again in "The Return of Doctor Mysterio" before becoming a regular in Series 10.
  • Beware the Silly Ones: He was nothing but comic relief in his first appearance but he proved able to fly the TARDIS in his next.
  • Butt Monkey: If there's an opportunity to insult him, Twelve will take it.
  • Character Development: Grew quite the backbone during his tenure.
  • Crouching Moron, Hidden Badass: Though he disputes the hidden part.
  • Fantastic Racism: Often makes some anti-human comments.
  • Foil:
    • To Twelve. Nardole is affable, pragmatic and unsuspecting while Twelve is snarky, theatrical and stands out.
    • To his predecessor, Clara Oswald. She wants the Doctor to drag her away across the universe while Nardole wants to stay on Earth and do their duty of guarding the Vault.
  • Morality Chain:
    • He, River and the Doctor are all fully aware that this in an Invoked Trope.
    • The Doctor might actually be his as Nardole seems to fear that he might return to his criminal roots one day.
  • Mysterious Past: In Series 10, he lists off several Noodle Incidents that raise more than a few questions about his origins. He supposedly doesn't know where he came from, has a compulsive need to start black markets, went on the run and changed his face to do so, was once blue, dated a voice actress, had an imaginary friend who left him for someone else and his left hand isn't his original one but one that he won in a contest.
  • Noodle Incident: Ruled the Byzantine Empire in the 12th century for a time. He was firm but fair.
  • Obfuscating Stupidity: How the Moff explained away his Early Installment Weirdness.
  • Really 700 Years Old: 237 to be precise.
  • Servile Snarker: He may essentially be the Doctor's butler but he can match Twelve quip-for-quip.
  • Took a Level In Badass: Goes from being a bumbling sidekick to being able to pilot the TARDIS and being allowed to kick the Doctor's ass.
  • Unexplained Recovery: It's vaguely touched upon that the Doctor built him a new body (with cheap human lungs, invisible hair, glass nipples, and some robotic parts) but it's never really explored in detail.
  • Unfazed Everyman: Even moreso than his predecessors. The only time he really panics is when the Doctor is going to do something stupid or when the monster is in close proximity.
  • Vitriolic Best Buds: With Twelve.
  • You Are Better Than You Think You Are: Despite their banter, the Twelfth Doctor thinks very highly of Nardole's moral character as seen when he tasks him with guarding the solar farmers from Cybermen. Nardole reluctantly agrees.
  • You Wouldn't Like Me When I'm Angry: Don't make him go squeeky-voiced.

Bill Potts

A cafeteria worker at St. Luke's University who becomes the Twelfth Doctor's personal pupil and eventual companion. And, for a brief time, the first Cyberman.

"Why does it say 'exterminate'? Wouldn't it be easier to just say 'kill'?"

Played by: Pearl Mackie (2017)
—Travelled with the Twelfth Doctor
  • And I Must Scream: During her time as a Cyberman.
  • Badass Gay
  • Black and Nerdy: A self-professed sci-fi lover.
  • Butch Lesbian: Downplayed as the real characteristic of this is everyone calling her "Bill".
  • Chekov's Gun: Having been able to fight off the Monks' conditioning, she can overcome the Cybermen emotional inhibitor.
  • Chubby Chaser: She gave extra chips (fries) to a girl she liked. This resulted in the girl gaining a substantial amount of weight but Bill decided she liked it.
  • Constantly Curious: Always asking questions.
  • Earn Your Happy Ending: After waiting ten years for the Doctor and becoming a Cyberman, she gets to explore the universe with her crush. The novelization later says that she and Heather lived a happy seaside life.
  • The Everyman: Rivals Rose in how utterly normal she was when she first boarded the TARDIS.
  • Foil: After how close Twelve was to Clara, his relationship with Bill is more student/teacher.
  • Gay Best Friend: To Twelve and Nardole.
  • Gender Blender Name: Her full name is "Billie" but everyone just calls her "Bill."
  • Genre Savvy: Watched a lot of sci-fi. She knows Laser-Guided Amnesia when she sees it.
  • Only Known by Their Nickname: Only ever called "Bill."
  • Replacement Goldfish: Maybe? In their early conversations, the Doctor often looked at his picture of Susan Foreman so at the very least, Bill had some similarities to Susan. He also seems quite eager to slide into a paternal/grandfather role around her.
  • Straight Man and Wise Guy: The Wise Guy to Twelve's (failing attempts) at being a Straight Man.
  • Swiss Army Tears: They summoned Heather and reactivated the Doctor's ability to regenerate after he'd died too suddenly for regeneration to occur.
  • Squee: Quite happy to meet not just one of the Doctor's old faces, but the Doctor's first face.
  • Torso with a View: Briefly.
  • Unwilling Roboticisation: She first gets a prosthetic heart, then the Master tricks her into becoming a Cyberman.
  • The Watson: Lampshaded in her conversation with the First Doctor where she says that "questions are kinda [her] thing."
  • Working Class Hero: Couldn't afford to go to university but still became a hero across time and space.
