"There are some corners of the universe which have bred the most terrible things. Things that act against everything we believe in. They must be fought!"The various races who encounter the Doctor in Doctor Who. For specific members of these races, see their respective character sheets.As with all Doctor Who characters, they appear not only in the televised adventures, but also in the Doctor Who Expanded Universe branches.
— Second Doctor, "The Moonbase"
open/close all folders
Classic Series Debut
Thals (First, Third and Fourth Doctors)
Thals were one of two sapient races native to the planet Skaro. The other race were the Kaleds, who eventually became the Daleks after a long and bitter war against the Thals.
- Actual Pacifist: After a thousand years of war, they refuse to fight the Daleks again.
- Arch-Enemy: With the Kaleds. The war between the two races lasted a thousand years. They are also sometimes this to the Daleks but far less so than the Doctor.
- Beauty Equals Goodness: The Thals resemble blond humans and are therefore good. The Daleks are blobs in metal tanks and are therefore evil.
- Human Aliens: Just like the Kaleds, they are visually indistinguishable from humans and Time Lords.
- Light Is Not Good: During the War, the Thals had blond hair, wore western-style green uniforms and generally looked like the Anglo-American good guys to the Third Reich-esque Kaleds, but were just as savage and genocidal as their enemies.
- Not So Different: Genesis of the Daleks shows that the Thals could be just as cruel and bloodthirsty as the Kaleds. However, by the time of The Daleks, they've become pacifists. By Planet of the Daleks, as pictured, they've regained a willingness to fight when necessary.
- People Of Hair Colour: The Thals have blond hair and light eyes, in contrast to the brunette hair and dark eyes of the Kaleds. Ironic, considering the Kaleds are very much Space Nazis.
- Took a Level in Kindness: Originally they were just as bloodthirsty and evil as the Kaleds, but the effects of the war caused them to realize the errors of their ways and they became pacifists ... until the Doctor convinces them otherwise.
Sensorites (First Doctor)
A telepathic humanoid race native to the Sense Sphere. Appeared in "The Sensorites".
- Ditto Aliens: They themselves cannot effectively tell the differences between each other without first having become familiar with them, and relies on sashes and other decorative garb to identify important individuals.
- Telepathy: They communicate each other if they're not close to each other.
- Klingon Promotion: If any of the Elders die, they will be replaced with another one who is next to the rank.
- Weaksauce Weakness: The race are prone to darkness and loud noise.
- Yellow Face: They're based off of Chinese Communists.
Zarbi (First Doctor)
Giant alien ants from the planet Vortis. Appeared in The Web Planet and have shown up in the expanded universe a few times since, usually as a punchline.
- Anti-Villain: The Zarbi are actually being brainwashed by the Animus.
- Big Creepy-Crawlies
- Bug War: Uniquely, a war between two different factions of bugs. The ant-like Zarbi and the Menoptera, a race of butterfly people.
- Insectoid Aliens: Planet Vortis is full of them. The Doctor and his companions are the only non-insects in the entire serial.
- Meaningful Name: Zarbi is a slang word in french for Bizarre. Bizarre means Weird when translated in English.
- People in Rubber Suits: Really obvious. A rather infamous example, meaning the Zarbi are somewhat of a joke among old-school fandom.
- Running Gag: Whilst the Doctor tangles with formidable foes such as the Daleks, the Cybermen and the Master, Iris Wildthyme keeps running into the Zarbi.
Drahvins (First Doctor)
Beings from the Planet Drahva. They have very few men.
- Absolute Xenophobe: Maaga and by implication all the other upper-caste Drahvins.
- Ace Custom: The Drahvins are so wedded to their caste system that they self-destructively only give their leader caste the good weapons.
- Bad Boss: Seems to be required by Drahvin law and/or custom.
- Beauty Equals Goodness: Defied.
- Brainless Beauty: The barely sentient Drahvin clones.
- The Cameo: River Song namedrops the Drahvins as members of the Alliance in "The Pandorica Opens".
- Evil Cannot Comprehend Good: The Drahvins can't understand self-sacrifice.
- Fantastic Caste System: The Drahvins have a caste system based on social insects, of female leaders, female workers, and a few males kept solely for the female leaders to sexually reproduce.
- Lady Land: On the planet Drahvin, women dominate the planet. A few men are kept, presumably for breeding, while the rest are killed. Oddly, Maaga doesn't immediately understand when Steven asks her if all the inhabitants of her planet are women, perhaps demonstrating how utterly insignificant and out of mind the men of Drahvin are.
Macra (Second and Tenth Doctors)
A race of enormous crustaceans who fed off gases that were poisonous to most other species. The Second Doctor first encountered them when they had enslaved a human colony. The Tenth Doctor later discovered a new breed of Macra living under New New York.
- Anti-Villain: In a way. In "The Macra Terror", they only enslaved the colonists because the humans had colonised the Macra home world without asking. In "Gridlock", they're merely non-intelligent animals who are defending their territory.
- Deadly Gas: Their primary food source.
- Evolutionary Levels: After billions of years, the Macra the Tenth Doctor encounters on New Earth have devolved from sapient beings to mindless beasts.
- Giant Enemy Crab: Big enough to crush cars in their pincers.
- Long Bus Trip: Forty years between "The Macra Terror" and "Gridlock".
- Villain Decay: Invoked. After a few billion years, the Macra devolved into a much less intelligent form, so instead of being invisible puppet masters, they're just scavengers living off car fumes.
Ice Warriors (Second, Third, Eleventh Doctor, and Twelfth Doctors)
Played by: Bernard Bresslaw, Roger Jones and and Michael Attwell (1967); Tony Harwood (1967–69); Sonny Caldinez (1967–74); Steve Peters and Graham Leaman (1969); Alan Bennion (1969–74); Spencer Wilding (2013)A race of reptilian aliens who come from Mars, the Ice Warriors were the third species of big bads in Doctor Who — resulting in several appearances throughout the Second and Third Doctor eras... but they basically vanished with the end of the Third Doctor's run on the show in 1974 (around the time that space probes in Real Life proved Mars to be barren). Efforts were made to bring them back in the original series from time to time — but the final attempt was scheduled to be in the 1990 season of Doctor Who... and the show was canned/put on hiatus in 1989.They did eventually get nods in "The Christmas Invasion" and "The Waters of Mars", and finally made their return in the 2013 second half of series 7, during "Cold War".

Voiced by: Nicholas Briggs (2013)
- Animated Armor: They find leaving their armor deeply shameful, but if they are forced to do so they can remote-control it.
- Big Bad Ensemble: Before they vanished, these guys were the third biggest alien villains for the Second and Third Doctors.
- Cyborg: According to "Cold War", they're this; it helps them deal with Mars' freezing conditions.
- Disproportionate Retribution: By their code, an attack on one Ice Warrior is an attack on all of them. And they respond in kind, even if the attack doesn't even harm the warrior in question.
- Heel–Race Turn: Their first two serials have them as the villains, but since Jon Pertwee's first brush with them they've alternated between friends and foes (one of them even became a companion in the Expanded Universe).
- Last of Their Kind: Since Mars is somewhat inhospitable to them after some unspeakable event in their past, it's a little hard for the species to continue — especially when they have a nasty habit of getting wiped out whenever they encounter the Doctor. To make matters worse, the Expanded Universe puts the Doctor essentially at fault for said unspeakable event. Whoops. This appears to have been retconned as of "Cold War", with the Doctor saying Martians survive on other planets, and a Martian ship appearing at the episode's end. "Empress of Mars" reveals the survivors lasted on the dead world for some time in suspended animation before being evacuated by a fleet from Alpha Centauri.
- Mighty Glacier / Fragile Speedster: Both in "Cold War", depending on if they are in or out of their armor. Since they can remote control their armor, they can even fill both roles at once. However, for cultural reasons they remain in their armor.
- Monster Lord: Their leaders are smaller, slimmer and less heavily-armoured than the usual soldiers. They are often referred to in fanon as "Ice Lords", although this is never used in on-screen dialogue.
- Oh My Gods!: They tend to swear by "the moons" (Phobos and Deimos).
- Proud Warrior Race
- Subverted in the Doctor Who New Adventures novel The Dying Days where the Ice Warriors encountered there claim to be this but are psychotic monsters.
- Played Straight in "Empress of Mars" where they were only fighting because the humans attacked them first. After the commanding officer saves their queen from a Jerkass soldier trying to hold her hostage, he offers to let her execute him in return for letting the other soldiers go free. She's so impressed with his courage that she not only agrees, but spares his life, on the condition that he swears loyalty to her and the Ice Warriors. He agrees.
- Put on a Bus: They basically vanished completely after 1974, but returned in the revival with 2013's "Cold War" and 2017's "Empress of Mars."
- Red Eyes, Take Warning: Their armour has red-tinted lenses.
- The Reptilians
- Sssssnaketalk: They often speak like this due to them being reptilian.
- Super Soldier
- Zombie Gait: This, combined with their constant shallow breathing, gives the impression that our heroes are in fact being chased around by overweight smokers. They feel compelled to sprint from them anyway.
- As it turns out, this is down to their armour. Out of it, they are terrifyingly fast. Fortunately, Ice Warriors see leaving their armour as deeply dishonourable... which means that when one does leave it, the situation is desperate, both for the Ice Warrior and their unfortunate opposition.
Quarks (Second Doctor)
These guys were originally intended to replace the Daleks. Really. The Quarks first appeared as robotic servants to the titular race in The Dominators and later showed up as independent villains of their own in Sixties comic strips.
- Cute Machines: It looks like they just want a hug. The high pitched voices don't help.
- Mecha-Mooks: For the planet conquering Dominators.
- Merchandise-Driven: As Terry Nation was keeping the Dalek rights to himself in the late Sixties, the Quarks were created to appeal to children in the same way the Daleks had. Needless to say, the Quarks didn't have quite have the same staying power as the pepper pots from Skaro.
- Tin-Can Robot:
Krotons (Second Doctor)
A crystalline race of aliens. Along with the Quarks, the Krotons are villains from the Sixties who are fondly remembered for having endearingly silly designs. They are also notable for being the first in a long line of Doctor Who monsters created by Robert Holmes.
- Beware the Silly Ones: In the Eighth Doctor Adventures novel Alien Bodies, a lone Kroton destroys an entire battleship full of Daleks.
- Mechanical Lifeforms: The Krotons resemble robots made of crystals.
- Our Monsters Are Weird: They have a Tin-Can Robot appearance but are actually sapient tellurium crystals that are technically immortal, with the closest thing to death that they have being to 'exhaust' (turn into a gaseous state and leave their vessel). The implication (made explicit in the books) is that they can possess any machine into becoming their body. They are blind, power their machines with mathematical aptitude, Mind Rape people in order to get the power, breathe fluid through hose lines in their chest, and have inexplicable accents.
- Starfish Aliens: Living crystals who resemble robots and power their spaceships with mental energy. Even by Doctor Who standards, they're pretty weird.
- Weakened by the Light: They have poor eyesight in daylight and so have trouble moving around.
Time Lords (Second, Third, Fourth, Fifth, Sixth, War, Tenth, Eleventh and Twelfth Doctors)
"And what of the Time Lords? I always thought of you as such a pompous race. Ancient, dusty senators, so frightened of change and chaos..."The Doctor's own people. They hail from the planet Gallifrey and claim to be the universe's first civilization. Time Lords can travel through time and manipulate it to a huge degree. Though they generally operate under a policy of non-interference, they've also appointed themselves the guardians of the space-time continuum, and (at least in the Expanded Universe) look rather askance at attempts by the "lesser races" to develop time travel. The Doctor claims to have left Gallifrey in opposition to its xenophobia and stagnation.
— Brother Lassar, "School Reunion"
- 0% Approval Rating: Thanks to the Time War, the rest of the Universe went from treating them with bemused apathy to loathing them like they do Daleks. In "The Night of the Doctor" it's out-right stated that there's no difference between them and the Daleks anymore. They're so hated that they have to hide at the end of time for their own safety; otherwise they'd have another Time War on their hands.Clara: You're monsters. Here you are, hiding away at the end of time. Do you even know why? Because you are hated. You are hated. By everybody.
- Absolute Xenophobe: Nowhere near as bad as the Daleks, but the Time Lords don't like anyone visiting their planet, they don't like to leave home, and they all seem to live in a couple of giant cities encased in massive glass domes.
- Abusive Alien Parents: Prospective Time Lords are taken to the Academy at the age of eight, and it starts with a glimpse of the raw time vortex that's been known to drive people insane. The only alternative seems to be the army, which scared the young Doctor even more.Master: It began on Gallifrey, as children. Not that you'd call it childhood. More a life of duty.
- Abusive Precursors:
- They used to amuse themselves by snatching people out of time, dropping them in the Death Zone and watching them fight.
- The Minyans of the former planet Minyos see them as gods, and they view their gods as evil.
- Alien Non-Interference Clause: Officially, which is part of their dislike of renegades like the Doctor who get "involved". Unofficially, they are perfectly willing to send the Doctor (or even the Master) to fix their messes or perform tasks they don't want to get their hands dirty with. They justify this by saying the Doctor is a 'special' case.
- Anti-Villain: Until The Trial of a Time Lord, the Time Lords were often antagonists to the Doctor but were originally on the side of good. (Television Doctor Who, up until the present, has portrayed them very inconsistently, sometimes as good, sometimes as evil and often as something in-between.)
- Ascend to a Higher Plane of Existence: This is their ultimate plan in "The End of Time". Or Rassilon's, and no-one dared argue with him. The method they intended to use would have had devastating consequences for the rest of reality, letting the Time War loose if nothing else.
- Awakening the Sleeping Giant: They did this to the Daleks, and the Daleks did this in turn. The Time Lords had spent most of their existence not getting involved and not bothering other species, but for a race of shut-ins, they managed to fight the Daleks for hundreds of years. And then the war went temporal.
- Big Brother Is Watching: "The Deadly Assassin" reveals they have files on every Time Lord (except the Master - he destroyed his). Other stories show they can pop the Doctor anywhere in time and space they want.
- Blue and Orange Morality: They do on some occasions express a view of life as something to be preserved, yet they obey their Alien Non-Interference Clause without hesitation.
- Body Horror: Can apparently happen if regeneration goes wrong. In his final moments the Ninth Doctor mentions he might end up with two heads, or no head at all, and the Eleventh once mentioned he had an aunt with two heads (and bad breath). And then there's what happens if they run out of regenerations.
- Break the Haughty: The Time War brought a Higher-Tech Species to their knees.
- Can't Argue with Elves: They're cleverer than you, more intelligent than you, and arguing with them is pointless. Even the Doctor thinks like this and it is why he needs a Morality Chain in his companions.
- Corrupt Bureaucrat: The high society is loaded with arrogant and greedy officials that bend rules. It's why the Doctor doesn't like being associated with them.
- Crystal Spires and Togas: On the surface with their gorgeous Citadel and fancy regalia. But scratch it and you find a Deadly Decadent Court, where "simple palace revolutions" are the norm.
- Depending on the Writer:
- Are they a basically well-intentioned Higher-Tech Species devoid of sympathy for individual lesser beings ("The War Games"), uncomplicatedly good protectors of the universe ("The Three Doctors"), pompous but weak dotards who don't really understand their own role or technology any more ("The Deadly Assassin"), or a powerful but almost entirely self-serving Deadly Decadent Court ("The Invasion of Time" and all TV and expanded universe stories subsequently)? Depends what the scriptwriter thought.
- Are all Gallifreyans full Time Lords? It's a question that's kept the fanbase puzzled for eons.
- The Dreaded: Before the Time War, the rest of the universe treated them with a mixture of vague respect, bemused apathy and in some cases, covetousness of their power. During and after the Time War, they were easily as feared as the Daleks, if not more so - a mere untranslated message during The Time of the Doctor made every single living creature that detected it feel fear and come to investigate with weapons hot; and they didn't even know who sent it. Once it's revealed that it's the Time Lords, waiting for the okay from the Doctor to let them back into the universe, the result is a mass Oh, Crap!, and the various alien races are willing to blow up the planet simply because the crack in reality that the transmission is coming through is on it. It gets to the point where, in the same episode, the Doctor threatens to 'unleash the Time Lords' on the Daleks, who are absolutely terrified of the prospect. Considering that the Daleks are the Big Bad of the Whoniverse, this is saying something.
- Once they return to the universe, they have to hide at the end of the universe because everyone's so scared of them.
- Dying Race: Due to the Last Great Time War, the Time Lord race was rendered functionally extinct. In "The Day of the Doctor", the timeline is altered by the combined efforts of thirteen incarnations of the Doctor, but this led to the entire population of Gallifrey being shunted into a pocket universe and lost. The only Time Lords currently known in the universe are the Doctor, Jenny (who's currently MIA), River Song (who's sort of dead), and the Master, who's still as unkillable as ever. As for the Doctor's own family, he claims they are now all deceased, but we still don't know precisely what happened to Susan after Series 4 of the New Eighth Doctor Adventures.
- As of "Hell Bent", they've returned to the main universe, but their reputation means they've had to hide Gallifrey at the end of time.
- Everyone Has Standards: Before they went off the rails, they at least had enough decency in "Genesis of the Daleks" to recognize that the Daleks being the sole dominant life-force in the Universe would be a very bad idea.
- Face–Heel Turn: Between "The Trial of a Time Lord" and the Time War scenes of "The End of Time", the Time Lords become Knights Templar in the Time War against the Daleks.
- Zig-zagged. It's later shown that this extends only to the Time Lord Council, especially under the leadership of the revived Rassilon, and even then there are some Punch Clock Villains, who're only going along with it because Rassilon will vaporise them if they don't. The soldiers actually fighting the war and the civilians caught in the crossfire are a lot more sane.
- Fantastic Caste System: The higher echelons of Time Lord Society appear to live in either the Capitol or Arcadia. Those who live in the Dry Lands in Rassilon's words "don't matter" - whether they're even full Time Lords or not is up for debate.
- Gender Bender: Missy - aka the Master - proves that Time Lords can change gender when they regenerate.
- The Corsair, an old friend of the Doctor's, was also said to have both male and female incarnations. In the novelisation of a never-completed Fourth Doctor TV story, "Shada", the Doctor causally switches between male and female pronouns when reminiscing about the Corsair.
- Borusa is also implied to have had a female form at some point in his past in Engines of War. The general ease at which Time Lords adapt to differently sexed bodies (without any gender identity worries) seems to imply that they are all gender fluid, though with regeneration thrown into the mix it's not quite the same as human gender fluidity.
- In "Hell Bent" the General regenerates into a woman and comments that it's good to be "Back to normal" after her only male incarnation, suggesting that there's some sense of gender identity present, if in a rather vaguer sense.
- Thirteen sees the Doctor's first confirmed gender switch.
- Good Is Not Nice: They are the most powerful and mighty race in the universe, self-appointed guardians of all time and space, billions of years old and unchallenged for ten million of them by the time of Trial of a Time Lord. With such credentials under their belt, they are naturally boastful, arrogant and extremely corrupt.
- He Who Fights Monsters: If the Doctor hadn't ended the Time War the way he did, the Time Lord leadership would have destroyed all of reality so they could survive as pure energy. This makes them little different from the Omnicidal Maniac Daleks they had been fighting.
- "The Day of the Doctor" reveals that in the face of the Daleks assault, the military had been forced to turn to the Doomsday Weapons kept in the Forbidden Vaults, designed during the Dark Times on Ancient Gallifrey. By the last day of the Time War, they'd used them all.
- Healing Factor: They heal pretty quickly anyway, shaking off gamma infused lightning strikes in less than a minute. But it only really shows when the regeneration has started. Before the Time Lord changes completely, the body heals all the injuries and may rejuvenate the individual.
- Higher-Tech Species: They are the higher tech species. A vehicle that can travel anywhere in time and space, be Bigger on the Inside and disguise itself as anything around it as well as generating food and drink for its whole crew... is laughably primitive by their standards.
- Human Aliens:
- Time Lords are visually indistinguishable from humans, though anyone who takes even a slightly closer look, or who has medical training, will notice some differences straight away.Amy: You look human.
Eleventh Doctor: No, you look Time Lord. We came first.
- According to the Doctor Who Expanded Universe, they're the reason so many Whoniverse species are human-looking.
- Time Lords are visually indistinguishable from humans, though anyone who takes even a slightly closer look, or who has medical training, will notice some differences straight away.
- Human Outside, Alien Inside: On the surface they (usually) look human, but underneath everything's different.
- I Meant to Do That:
- The Time Lords as a whole seem convinced they're 'allowing' the Doctor freedom, ignoring the fact that he ran away from them, and constantly takes every chance he gets to stay away from them.
- Subverted to an extent. Stories like "Genesis of the Daleks" and The Trial of a Time Lord prove they can move the Doctor and his TARDIS anywhere in time and space; they usually don't unless they need him for something.
- Impossibly Tacky Clothes: To the point you start wondering if it's genetic rather than cultural. Even the (very few) co-ordinated Time Lords will do a little something weird to throw the entire ensemble right into WTH, Costuming Department? territory. Most just skip the whole "spot the odd thing out" option and go straight to full-on eye-bleed.
- Last of His Kind: The Doctor, due to having wiped the others out at the end of the Time War. Or so he believed.
- Leitmotif: "This Is Gallifrey", which acts as the theme to both the planet Gallifrey and the Time Lords themselves.
- Mercy Invincibility: A non-video game example. While the aftermath of a regeneration can leave them mentally out-of-sorts, the energy lingering in their systems lets them re-grow whole limbs.
- Mystical High Collar:
- Their formal robes have notoriously large collars.
- Hilariously, a Freeze-Frame Bonus from John Smith's Journal in "Human Nature" reveals that the Doctor, in his youth, "could never get the collar right".
- Never Speak Ill of the Dead:
- The revival Doctor is a lot fonder of Gallifrey than he ever was when it was still there. When it looks like the Time Lords are coming back, the nostalgia goes out the window and he grabs the nearest revolver.
- In "In the Forest of the Night", he calls Earth "his world", perhaps exactly because this trope is no longer in play - now that Gallifrey's been saved, he no longer has to feel guilty about feeling more at home with the "pudding brains".
- Nice Hat: In "The Deadly Assassin", we were shown Time Lords in their full ceremonial costumes, including their distinctive headgear. Though these were supposed to be "seldom-worn", they have become iconic; it's almost unheard-of to have a story where the Time Lords don't get to wear their Nice Hats. The Doctor has a dim view on Time Lord fashion sense.
- No Man Should Have This Power: The abuse of their power in the past is why they developed their Alien Non-Interference Clause - officially. Subverted in that the High Council is more then willing to abuse their power when they see fit.
- Omnicidal Maniac: Their plan in "The End of Time" involves the destruction of time itself.
- The Omniscient Council of Vagueness: They tended to be this or the Not-So-Omniscient Council of Bickering, which is why RTD drop-kicked them out of the revived show.
- Pet the Dog: In "Time of the Doctor", the Time Lords used the cracks in the universe to grant Eleven a new cycle of regenerations, allowing him to regenerate into Twelve. A more cynical viewpoint is that they only did so because the Doctor is the only one able to bring them back into the universe, making this a little more self-serving on their part.
- The Philosopher King: The Time Lords' entire hierarchy is based on academia, with everyone belonging to a specific College. Training at the Academy begins as age 8.
- Really 700 Years Old: A single Time Lord regeneration can, with proper care and attention, last for hundreds of years, sometimes more.
- Smug Snake: The average Time Lord is very confident in themselves and their abilities. Some of it is admittedly justified, but still...Fourth Doctor: Who are you? Don't you realise how dangerous it is to intercept a transmat beam?
Time Lord: (with indescribably smug air) Oh, come now, Doctor, not with our techniques. We Time Lords mastered such simple things when the universe was less than half its present size.
- Snobs Vs Slobs: Gallifreyans who don't go to the Academy and become full Time Lords go into the army instead; the Academy is the more respected option - the Doctor did not want to go into the army at all.
- Space Elves: Long-lived, scholarly, reclusive, ancient, frequently haughty, devious, powerful and usually robed.
- Spare Body Parts: Their most obvious and widely-known alien trait is that they have two hearts. Though the Doctor shows that the second heart isn't just for show, being nearly incapacitated whenever one of his hearts stops. Later, it is stated that they have three brain stems.
- Sufficiently Advanced Alien: As a result of being the Higher-Tech Species. Even the Daleks, their most dangerous foe, never came close to matching the Time Lords' skill at time travel and transcendental technology.
- That Man Is Dead: Most renegade Time Lords and Ladies who leave or are exiled from Gallifrey forfeit their names and take up "titles" instead, and are addressed as such by their fellow Time Lords. Examples include: the Doctor, the Monk, the War Chief, the Master, the Rani, and the Corsair. Why they do this has never been explained.
- Training from Hell: At the age of eight, Time Lords attending the Academy are taken in front of the Untempered Schism, a gap in the fabric of reality in which the entire Time Vortex can be seen. According to the Doctor, "Some would be inspired, some would run away, and some would go mad". The Doctor was one of the ones who ran away (and never stopped) and he suspects the Master was one of those who went insane.
- Ungrateful Bastard: The Doctor has saved their bacon multiple times throughout the series and they repay that by alternating between treating him with outright contempt, letting him wander the Universe without a fuss, or trying to kill him, like when they struck a deal with the Valeyard so he would have all of the Sixth Doctor's remaining regenerations. This is eventually zig-zagged in "Hell Bent". While Rassilon and possibly the High Council are these, the rest of Gallifrey are certainly not.
- Well-Intentioned Extremist: They really don't get involved in Universal affairs unless it's drastic: when they foresaw a future when the Daleks would be the dominant species in the Universe they came to the conclusion that wiping them out from reality would be the best course of action. This led them down a very dark path.
Autons (Third, Ninth, and Eleventh Doctors)
Played by: Hugh Burden (1970), Hamilton Dyce (1970), Noel Clarke (2005), Marcus O'Donovan (2010), David Fynn (2010), Clive Wood (2010), Arthur Darvill (2010)The Autons are evil living plastic servitors that are controlled by the squid-like Nestene Consciousness. Their best known trick is posing as shop dummies and bursting out of high-street windows, although their second appearance had them trying to kill people in increasingly bizarre ways. They don't need to be humanoid, either; any seemingly inanimate plastic object will do—chairs, toys, even a trash can. The Consciousness can also create more sophisticated "facsimiles" (referred to as "Nestene Duplicates" in the revival) that perfectly mimic the appearance of others... and may even believe their own cover story.
- Animate Inanimate Object: So long as it's made of plastic, the Nestenes can bring it to life and kill people with it.
- Arm Cannon: Well, hand cannon.
- Breakout Villain: One of the original run's most iconic monsters, despite only appearing three times. The image of mannequins stepping out of shop windows and attacking was vivid enough for them to get into the revival's first episode.
- Everything Trying to Kill You: As the Third Doctor's tenure was largely confined to the Home Counties in the present day for budget reasons, the Autons inaugurated the grand old Doctor Who tradition of everyday objects trying to kill you.
- Hive Mind
- Immune to Bullets: The original versions helped inaugurate a long tradition of UNIT's guns being utterly useless against the threat of the week.
- Manchurian Agent: Some later model Autons come with fake memories.
- May Contain Evil
- Mooks: The Autons are the Nestene foot-soldiers, doing the work disposing of any threat, since the Nestene lack the mobility to do so themselves.
- Murderous Mannequin
- Ridiculously Human Duplicates: Some of them are created as Uncanny Valley versions of humans (Auton!Mickey) but others are so indistinguishable from human that they even believe their own cover stories (the "Romans" and Auton!Rory).
- Step Three: Profit: In the Doctors Revisited - Jon Pertwee special, Steven Moffat felt the Autons' original invasion suffered from this.Steven Moffat: It's a genius idea. Conquering the world with shop dummies! For no particular reason other than it's really scary. What was the plan, exactly? We're going to conquer Earth, by planting... shop dummies in windows.
Steven Moffat: Terrifying idea. Brilliant. And of course, like all great Doctor Who ideas, completely bonkers.
- Uncanny Valley: In-universe. Autons often attack and replace targets, but they tend to miss certain details. Like how human skin isn't that smooth and shiny. Averted with the ones in 2010, who look and act completely human until the moment arrives.
Homo reptilia note (Third, Fifth, Eleventh and Twelfth Doctors)
Silurians voiced by: Peter Halliday (1970)
Silurians played by: Norman Comer, Stuart Blake and Vincent Brimble (1984), Neve McIntoshnote (2010present) and Richard Hope (2010–12),note Stephen Moore (2010)

Silurians played by: Norman Comer, Stuart Blake and Vincent Brimble (1984), Neve McIntoshnote (2010present) and Richard Hope (2010–12),note Stephen Moore (2010)
Sea Devils played by: Pat Gorman and Peter Forbes-Robinson (1971), Christopher Farries (1984)
"This land is ours. We lived here long before the apes."A species of highly intelligent creatures that evolved during the age of dinosaurs, the Silurians were distantly related to their aquatic relatives, the Sea Devils. Both species went into hibernation upon thinking that the moon was about to collide with the earth. It didn't; the disaster never happened, but their disappearance cleared the way for humans to take over as the dominant sentient lifeform. Eons later, they awake, and fight the upstarts (read: us) for control of Earth. It never ends well. The 21st century series gave the Silurians a very heavy redesign, with only two eyes, a more generally humanoid appearance (their battle armour has a mask that looks closer to the original face), and a multipurpose, venomous tongue. This is explained that the Silurians (unlike other species) showed an important intraspecific variation (vast differentiation between breeds), such as the number of eyes, the formation of their pupils or the color of their skin with a wide range of subspecies (one of which is Sea Devils).
- The Ark: One of their many survival plans built was a space-faring version, containing a few thousand Silurians and a zoo's worth of dinosaurs. Unfortunately, a space pirate boarded the vessel and flushed them all out the airlock.
- Attack Animal: The Silurians of Wenley Moor used a dinosaur like creature. In "Warriors of the Deep", they used a Myrka (A genetically modified animal made by the Silurians from
a pantomime horsean unknown deep-sea creature.)
- Beneath the Earth: They have laid dormant there for millions of years, and possess very advanced technology.
- Blue and Orange Morality: Some express the desire to reclaim Earth and exterminate humanity with the justification that they came first and that humans are encroaching on "their" world. The Doctor politely points out that it doesn't work that way.
- The Cameo: In "The Pandorica Opens" they are members of the Alliance, and watch as the Doctor is dragged to the Pandorica.
- Extra Eyes: The Silurians have a third eye, which glows when they exercise psychic powers (in their first appearance) or when they talk (in their second). It has, however, utterly vanished from the newest incarnation of the species appearing in "The Hungry Earth" / "Cold Blood" and "A Good Man Goes to War", who are handwaved as being a different branch of the same species, somewhat analogous to the difference between Humans and Neanderthals.
- Everything's Better with Samurai: An elite task force of Sea Devils called Elite Group One was dressed in secure, samurai-style armor
- Exposed Extraterrestrials: Silurians in "Doctor Who and the Silurians" and "Warriors from the Deep". Averted in "The Sea Devils" due to a concern about "naked Sea Devils running around on telly at teatime".
- Fantastic Racism: The average Silurian doesn't really have a high opinion of us "apes", and don't want to share the planet with us. For some of them, this applies to mammals in general. Even Madame Vastra has her moments.
- Insistent Terminology: They refer to Gene Lines rather than families, and some other touches.
- Kill 'em All: Has a distressing tendency to happen to them whenever they appear, despite the Doctor's best efforts. It's their fault at least some of the time, such as when a militaristic faction deliberately sabotages peace talks with humanity.
- Last of Their Kind: Every named Silurian in the episodes they show up in will make this claim. It was more understandable in the original series (and subsequent expanded universe tales), where it was literally a few dozen at best who survived. When a captive Silurian tries to claim this on the Doctor in "The Hungry Earth", he shuts her down pretty quickly. Likely, since the species seems to have had a variety of branches and different survival plans, they're simply wrong.
- Living Dinosaurs: They are sentient dinosaurs who evolved on Earth geological periods before humans did.
- Lizard Folk: They are an ancient race of reptilian humanoids that predate humans.
- More Deadly Than the Male: Since their reappearance in 2010, the female Silurians have been portrayed as more aggressive than the males. Much like real-life lizards, then.
- Multipurpose Tongue: Useful both for defending oneself and... um...
- Non-Mammal Mammaries: Well... the modern ones have them, anyhow.
- Not Evil, Just Misunderstood: They're portrayal in the revival series is this, as they're "kidnapping" attempts were merely examinations in trying to find out more about the humans.
- Overly Long Tongue: Which are capable of stunning an opponent upon contact.
- Proud Warrior Race:
- The Warrior Caste Silurians.
- Sea Devils may also fit this trope.
- The more recent versions of the Silurians avoid this trope. Yes, they have a military, but it's not the driving aspect of their culture, and they had a phenomenal grasp of science.
- Psychic Powers: Silurians who have the third eyes have shown the capability of harming organic beings, killing them or leaving them unconscious. Alternatively, they could revive a human (or Time Lord) that they had rendered unconscious with the third eye. Energies emanating from it allowed them to burn through walls and create tunnels. These Silurians also employed their third eye in less destructive tasks, such as activating their technology, opening passageways or creating force-fields to trap prisoners.
- Rage Helm: The warrior caste Silurian faceplates are organic in appearance, and could easily be mistaken as a real (albeit scarier) face.
- Red Scare: "Warriors of the Deep" is largely ham-fisted with Cold War metaphors up the wazoo. The Silurians were also a metaphor for the Soviets at the time, according to Word of God. The Sea Devils may have been this as well, but it doesn't seem as likely.
- The Reptilians: Although they are actually native inhabitants of the Earth.
- Taxonomic Term Confusion: Homo Reptilia? Considering the Homo genus is mammalian. (And that's aside from the oddity of "Silurian", a period in which reptiles hadn't yet evolved. The attempt to fix this with "Eocene" was, unfortunately, still wrong. Poor reptiles can't catch a break.)
- Ultraterrestrials: The first native sentient species on Earth, millions of years before humanity.
- Underground City: Have made a very impressive one where they remain in hibernation.
- Underwater Base: Sea Devils had thousands of underwater colonies dotted across the globe, each filled with millions of their kind. These bases were carved out of rocks and were generally covered in algae and seaweed. The colonies could be awoken en masse through the use of a sonic signal.
Primords (Third Doctor)
Mutated human beings, created as a result of exposure to ooze emitted by Project Inferno, an attempt to drill through to the Earth's core. At first the change manifested itself in the form of discoloured skin, violent behaviour and the body generating intense amounts of heat, but warmer conditions would cause the transformation to progress to its final stage, causing the victim to vaguely resemble an ape or werewolf.
- Achilles' Heel: Were very vulnerable to cold, which was the only surefire way of killing them. Well, that and throwing them off a tall building, which isn't always feasible.
- Ax-Crazy: At first, anyway, with people in the early stages of the transformation being inclined towards trying to beat people to death, either with their bare hands or whatever blunt instrument they have to hand. It actually seems to lessen after the transformation completes, when their MO switches more to actively trying to infect others.
- Immune to Bullets: Can easily shrug off multiple gunshot wounds right through the heart, just so long as that isn't combined with any sudden drops in their body temperature.
- Painful Transformation: Most of the transformations don't seem overly painful, but when the process is accelerated either by greater ambient heat (in the case of the parallel Benton) or exposure to a large amount of the ooze (as with Professor Stahlman), the change is depicted as being much more painful.
- The Virus: The first few Primords in either universe were created by exposure to the green ooze, but after that were capable of infecting others simply by touch.
- Was Once a Man: All of the victims started out as humans, before being infected either by ooze or other transformed people.
Axons (Third Doctor)
The Axons were part of a gestalt entity known as Axos that came to Earth to devour all of our planet's energy in the serial The Claws of Axos. They were defeated by the Third Doctor and UNIT. The Axons have also shown up in Big Finish Doctor Who (where they fought the Sixth Doctor) and the comic strip of Doctor Who Magazine (where they battled the Eleventh Doctor and Amy Pond in Japan.)
- Beauty Equals Goodness: Subverted. They appear as golden angelic humanoids but turn out to be monstrous.
- Glam Rock: The aesthetics of glam rock had a very big influence on the look of the Axons. It was the early Seventies, after all.
- Hive Mind: The seemingly individual Axons are all part of the same entity.
- Light Is Not Good: Gold and orange are the Axons' primary colour palette and they turn out to be evil.
- Organic Technology: The spaceship they arrive to Earth in. Considering that even the ship is part of the Axos hive mind, this makes sense.
- Trojan Horse: The Axons provide the human race with an alien fuel called Axonite, seemingly to help us with our energy crisis but actually to destroy us.
Ogrons (Third Doctor)
Ogrons were strong, ape-like humanoids of limited intelligence, typically used by other species as mercenaries. They were most often employed by the Daleks. They live in scattered communities on an unnamed planet on the outer fringes of the Milky Way, far from the central spaceways. The dominant lifeform on their home planet is a giant slug-like lizard named the Eater, and the Ogrons both pray to and are preyed on by it.
- Dumb Muscle: Ogrons are very strong and very stupid.
- Killer Space Monkey: Extremely strong and brutal.
- Mooks: For the Daleks and the Master.
- Servant Race: Are this to the Daleks. However IDW Comics seems to show them more as Punch Clock Villains.
- Shout-Out: The name may be derived from the mythological creatures ogres.
Peladonians (Third Doctor)
The Peladonians (or Pels) were a race of near-humans native to the planet Peladon who retained a feudal culture.
- Alien Sky: Their planet was known for being especially stormy. Dangers from the wind and rain were constant.
- Feudal Future
- Human Alien
- Skunk Stripe: One of the few ways to tell them apart from humans was the burgundy streak through their hair.
- Yellow Rocks: Their planet has a mineral called Trisilicate (Not to be confused with Magnesium Trisilicite). Word of God says Barry Letts took the name "Trisilicate" from a list of ingredients on the back of a tube of Boots brand toothpaste.
Draconians (Third Doctor)
The Draconians are an extraterrestrial race of reptilian humanoids. In later interviews, Jon Pertwee cited the Draconians as his favourite of all the monsters he had encountered during his time as the Doctor.
- Fantastic Slur: Some humans call them "Dragons."
- Feudal Future: The Draconian Empire was a vast spacefaring feudal civilisation centered on the planet Draconia, with a society stratifed along class and gender lines (for example, females were not permitted to speak in the presence of the Emperor) that was bound by a strong code of honour.
- Non-Mammalian Hair
- Reasonable Authority Figure: The Emperor.
- The Reptilians
- Snake Talk: They have a somewhat subdued version of snake talk, mostly hissing if a word ends on an 's' sound only.
- Wutai: Draconia is basically feudal Japan in space with reptile people.
Sontarans (Third, Fourth, Sixth, Tenth, Eleventh and Twelfth Doctors)
Played by: Kevin Lindsay (1973–75), Stuart Fell and Derek Deadman (1978), Tim Raynham and Clinton Greyn (1985), Christopher Ryan (2008, 2010),note Dan Starkey (2008, 2010–present)noteA race of the ultimate soldiers, the Sontarans are a clone race that live for war. Humanoid in appearance, the Sontarans are short, stocky, and insanely strong. They also look somewhat like potatoes, for some reason. If they show up, the plot is usually somehow tied to their never ending war against the Rutans (a race of... intergalactic jellyfish).
"Sontar HA! Sontar HA! Sontar HA!"
- Affably Evil / Faux Affably Evil: For all their violent, militaristic ways, they are unfailingly well-mannered among themselves and to anyone they aren't currently engaged in killing.
- Strax from "A Good Man Goes to War" is much more affable than most of his species, partly because of his time spent as a medic having made him less single minded and Ax-Crazy than the others.
- Before Strax IDW Comics had the Sontaran diplomat Stomm, who is one of the Doctor's allies during the story and is trying to attend peace talks (although it is pointed out the Sontarans want the Galaxy more peaceful so they can concentrate against the Rutans).
- The Big Finish audio adventure "Heroes of Sontar" pushes them into Affably Evil territory. Yes, they fight wars, but they're of the opinion that the ends justify the means, and if one part of the world has to die in order for them to overcome another, it's just a sacrifice, it's not For the Evulz.
- Strax from "A Good Man Goes to War" is much more affable than most of his species, partly because of his time spent as a medic having made him less single minded and Ax-Crazy than the others.
- Asskicking Equals Authority: Those in power? They fought their way up there.
- Attack Its Weak Point: The "probic vent" on the back of a Sontaran's neck is their only weakness.
- The Sontarans, characteristically, don't consider it a weakness since it forces them to always face their enemies.
- Author Appeal: Their entire creation was to appeal to author Robert Holmes and his distaste of militarism and colonialism. Also a bit of a Take That! against America at times, according to some people.
- Badass Boast: They tend to do this.
- Bald of Awesome / Bald of Evil: In equal amounts.
- Blood Knight: Unlike the Daleks, who want to destroy everything out of a sense of racial supremacy, the Sontarans just love to fight and need no particular motivation beyond that. They actually wanted to the fight in the Time War but were forbidden to do so.
- Blue and Orange Morality: Their values system resembles that of Ancient Sparta. To wit: "I hope someday to meet you in the glory of battle, where I shall crush the life from your worthless human form" is apparently a high compliment.
- Child Soldiers: Twelve is considered a ripe old age for Sontarans.
- Clone Army: The existence of different "batches" is used to explain why they're not 100% identical.
- Combat Medic: Considered a Fate Worse Than Death by them for obvious reasons. (That's not to say they can't be good at it, though.)
- Defeat Means Respect: Part of their Asskicking Equals Authority mindset: the Daleks or the Cybermen hate and fear the Doctor for repeatedly foiling their plans. The Sontarans (such as in "The Sontaran Strategm") have actually come to respect him as one of the most brilliant military strategists in the universe - he doesn't even need to lead his own armies, he just stumbles into situations and comes up on-the-fly with brilliant plans to defeat them. Verges on Your Approval Fills Me with Shame, as the Doctor doesn't like to think of himself as a military leader.
- Ditto AliensRattigan: How do you tell each other apart?
Stahl: We say the same of humans.
- Forever War: Their never ending war with the Rutans. Last time we heard, it wasn't going in the Sontarans' favor.
- Genius Bruiser: They don't posses the raw intelligence or knowledge of the Daleks or Cybermen, but underestimate their cunning at your own peril - they're quite subtle and farsighted if need be.
- Honor Before Reason: As they don't see death on the battlefield as a particularly bad outcome, they aren't opposed to giving their enemies a sporting chance... usually.
- Large Ham: They are well known for their bombastic speeches and "come at me, bro" attitude, which accounts for much of their popularity.
- Lawful Stupid, Chaotic Stupid: Played utterly straight in that if you challenge a Sontaran to a contest... any contest... they have to take that challenge. This weakness has actually made them a favorite of many authors.
- Subverted in "The Two Doctors" when a Sontaran tells the Doctor that he doesn't need to accept his challenge to an honorable duel because the Doctor isn't a Sontaran, and is thus below him.
- Literal-Minded: Sontarans don't have the best grip on human colloquialisms. Stahl was confused by Luke Rattigan saying something was cool, and Strax didn't understand the difference between bringing the morning newspaper up to Clara and throwing it at her head.
- The Magnificent: High-ranking Sontarans tend to carry such epithets, e.g. General Stahl the Undefeated, Commander Skorr the Bloodbringer, etc
- Martyrdom Culture: When a Sontaran is killed in battle, they're pretty happy. Commander Skorr's last word, upon being fatally shot in the front by Colonel Mace is "Wonderful..."
- One-Gender Race:
- To the point that the first Sontaran we meet mistakes Sarah Jane for a member of a different species to male humans. They are a clone race with their progenitor being a very militaristic general with a huge ego.
- Becomes something of a running gag with Strax, who similarly has trouble with the concept of two genders and refers to most women as "Boy", even after being repeatedly told otherwise.
- Proud Warrior Race Guy: Their entire society is apparently focused on and drive by war. A declaration by a Sontaran that he will "crush the life from your worthless (human) form for the glory of the Sontaran Empire" is a compliment because is means the recipient is designated a Worthy Opponent.
- Sociopathic Soldier: They live for war. They die for war. God help you if you get in their way or fight back.
Strax: [cheerfully] I hope someday to meet you in glory of battle where I will crush the life from your worthless human form. Try and get some rest.
- Subverted in "A Good Man Goes To War" by Strax the Combat Medic - the 'sociopath' side of this trope is apparently not a fixed racial trait, but something resulting from a lack of perspective. Even so, Strax frequently wishes his patients a speedy recovery and expresses the desire to one day kill them for the glory of the Sontaran Empire.
- Stomm (see above) says farewell to the Doctor in a similar manner.
- Spheroid Dropship: Almost all their ships are plain spheres.
- Staff of Authority: The Sontaran baton is a device carried by certain high ranking officers of the Sontaran Empire symbolizing rank as well as being functional.
- Violent Glaswegian: In The Name of the Doctor, it is revealed that Strax, having discovered the concept of the "weekend off", has taken to traveling up to Glasgow on vacation, in order to get into bar fights with the only people in the universe able to equal the Sontarans for sheer bloody-minded aggression.
- Younger Than They Look: We eventually learn, 38 years after their initial appearance, that due to being war-happy clones, they consider 12 years to be a pretty good
Wirrn (Fourth Doctor)
The Wirrn were a race of huge, parasitic insects. They initially appeared in "The Ark in Space" and have shown up in Big Finish Doctor Who as well.
- Big Creepy-Crawlies: The Wirrn stand at around 6-7 feet tall. Not too shabby for an insect race.
- Body Horror: You slowly and painfully begin turning into one of them once a Wirrn stings you.
- The Cameo: A dead Wirrn has a brief appearance in the The Stones of Blood.
- Dying Race: Their main hives have been wiped out, leaving them desperate.
- Fighting from the Inside: Like many infectious Doctor Who monsters, their victims can fight back with strong willpower and emotions.
- Insectoid Aliens: They resemble enormous wasp/ant hybrids.
- It's Personal: The reason the Wirrn try to devour the remaining humans on Nerva Beacon is because their hives across the galaxy were wiped out by pioneering humans.
- Off-the-Shelf FX: One of the most (in)famous examples in Doctor Who's history. A lot of the Wirrn effects were achieved with green bubblewrap, bubblewrap being a new invention in 1974. The effective acting in The Ark of Space goes a long way towards making the effect a bit more believable. This was given a nod in the revival series, when Clara Oswald finds a Sarcophagus full of green bubblewrap.
- The Virus: Once they sting you, you begin turning into one of them. The Doctor compares the Wirrn to real life parasitic wasps who lay their young inside caterpillars.
Zygons (Fourth, War, Tenth, Eleventh and Twelfth Doctors)
Played by: John Woodnutt (1975), Ian Marter (1975), Lillias Walker (1975), Jemma Redgrave (2013), Ingrid Oliver (2013, 2015), Jonjo O'Neill (2013), Joanna Page (2013), Nicolas Briggs (voice; 2013, 2015)The Zygons are a race of shapeshifting humanoids. After their planet was destroyed in a stellar explosion, they seek to colonise other planets, including Earth. Thanks to their well-realized design and the fact that "Terror of the Zygons" is considered a classic by fandom, the Zygons were very popular despite having only one appearance in the original run of the show. David Tennant has named the Zygons as his favourite Doctor Who monsters.
- Always Chaotic Evil: Averted. Most of the Zygons living on Earth just want to live in peace and at worst are Punch Clock Villains for Zygon High Command.
- Anti-Villain: Their home planet was destroyed so they understandably seek a new one. Unfortunately, they want Earth, an already inhabited planet.
- Attack Animal: The Skarasens (as seen in "Terror of the Zygons" and the Tenth Doctor novel "Sting of the Zygons") were massive creatures, large enough to crush a human with one clawed foot. They were cybernetically altered to suit the Zygons' purposes. They were vulnerable to no force short of a nuclear weapon. Their skins were highly durable and their skeletons were fused with an extremely tough alloy.
- The Cameo: In "Attack of the Graske" (a Tenth Doctor mini-sode) and "The Power of Three", albeit in human guises in the latter.
- Fatal Flaw: Their arrogance proves their undoing in "The Day of the Doctor".
- Foreshadowing/Cerebus Retcon: In "The Day of the Doctor" it is revealed that the destruction of the Zygons's homeworld mentioned in their first appearence was in fact an extremely early impact of the Time War on the Doctor's own adventures.
- Long Bus Trip: 38 years between "Terror of the Zygons" and "The Day of the Doctor". The Zygons had, however, had a handful of appearances in official novels and audio plays.
- Organic Technology: The Zygon ship seen in their first appearance. Played with in that while the interior is very organic, the exterior of the ship is a metal hull. "The Zygon Invasion" features a Zygon organic computer that the Doctor interacts with.
- Poisonous Person: They can poison humans with a touch. They also have, as the Tenth Doctor would attest, venom sacs in their tongues.
- Shapeshifter Baggage: Not only can they impersonate humans (who are much smaller than them), Zygons can also shapeshift into other non-humanoid lifeforms such as horses and (maybe) rabbits. In "The Zygon Invasion" the paranoid Colonel Walsh says that "any living thing" on Earth could be a Zygon in disguise.
- Shock and Awe: In "The Zygon Invasion" and "The Zygon Inversion", the Zygons can shoot electricity out of their hands that can turn humans into piles of hair and skin. It's not clear if this is a natural ability or some kind of bio-weapon.
- Stock Ness Monster: One of their Skarasens lived in Loch Ness for centuries and inspired the legend.
- They Look Like Us Now: The Zygons' ability to assume human form is what makes them so paranoia-inducing.
- Underestimating Badassery: Lampshaded in "The Day of the Doctor". Their arrogance meant they never stopped to consider that their own commander might have been killed and subsequently impersonated by Elizabeth I, instead of the other way around.Elizabeth I: I may have the body of a weak and feeble woman, but at the time, so did the Zygon!
- Voluntary Shapeshifting: They have the power to transform and reshape their bodies to impersonate humans and, as seen in "The Day of the Doctor", other non-humanoid lifeforms such as horses and (maybe) rabbits, although they do need to keep the being they're impersonating alive as a genetic and psychic "body print." In "The Zygon Invasion" it's claimed that this condition isn't needed any more; Osgood states that, "the rules have changed."
The Sisterhood of Karn
The Sisterhood of Karn (Fourth, Eighth, and Twelfth Doctors)
A mystic cult that originated on Gallifrey before they left and set up shop on Karn. They guard the Flame of Eternal Life which produces an Elixir that grants extended life; something Time Lords find handy if the regeneration process goes awry. They are currently led by the High Priestess Ohila.
- Ambiguous Situation: It's not entirely clear how close the Sisterhood are to Gallifreyans, biologically. Since they use the Elixir, they have no need for regeneration; what we do know is that they have similar mental powers like telepathy, but their powers are stronger than the Time Lords'.
- Humanoid Alien: One of many in the Whoniverse.
- Lady in Red: All of them wear red robes and habits.
- Lady Land: There are no male life-forms on Karn.
- Living Prop: In the revival, Ohila is the only member who speaks, the rest being literally props who just stand around.
- Magic Versus Science: A Brief History Of Time Lords suggests this is the reason why they left Gallifrey, as the increasingly scientific-minded Time Lords were beginning to become dismissive of the Cult's mystic beliefs, in a nod to the magic vs science portrayal of the Time Lords' origins in the Doctor Who New Adventures. On the Cult's part their Elixirs have the ability to give Time Lords a greater control over regeneration than normal, and they have stronger telepathic powers.
- Really 700 Years Old: Their Elixir grants immortality, but only within the vicinity of the Flame; try to drink it off Karn and it's useless.
- Small Role, Big Impact: They don't appear nearly as often as their Time Lord cousins, but they were instrumental in convincing the Doctor to enter the Time War and end it.
- Splinter Cell: They used to live on Gallifrey before having a disagreement with the Time Lords.
- We Used to Be Friends: The Time War really strained relations with their Time Lord cousins.
Krynoid (Fourth Doctor)
Carnivorous alien plants with big appetites. First showed up in "The Seeds of Doom" and have popped up in Big Finish Doctor Who a few times since. A Krynoid also faced off against the Eleventh Doctor in the e-book Tales of Trenzalore.
- Alien Kudzu: It infests entire planets.
- Body Horror: Their victims slowly start turning into giant plant creatures.
- Combat Tentacles: As Mary Whitehouse put it: "Strangulation by obscene vegetable matter."
- Green Thumb: Krynoids have the ability to telepathically control nearby plant life.
- Man-Eating Plant
- Palette Swap: The Krynoid costumes are just Axon (in their true form) costumes painted green instead of orange.
- Plant Aliens
- The Virus: When a Krynoid lands on a planet, it will consume all animal life to create more of itself.
- When Trees Attack: The Krynoid's ability to control plant life leads to this.
Rutans (Fourth Doctor)
Played by: Colin Douglas (1977)The Rutans (or Rutan Host) were a race of amorphous green blobs who waged war with the Sontarans.
- Arch-Enemy: To the Sontarans.
- Electric Jellyfish: Pretty much a space version of this.
- Face Stealer: The Rutan dissects the first two lighthouse operators in order to learn enough human physiology to take the form of Reuben for the final two episodes. Later victims it just kills.
- Forever War: They've been at war with the Sontarans for a long time, and they'll still be at it thousands of years later. From what little we know of their war, the Rutan seem to have the upper hand most of the time.
- The Ghost: They're appeared a grand total of once in the series, compared to their nemesis race. They do a little better in the wider Who media (once in an Eleventh Doctor Adventure game, a very short Story Arc with the Fifth Doctor in Big Finish Doctor Who, etc), but appear nowhere near as much as the Sontarans.
- Insignificant Little Blue Planet: The Doctor is quite surprised by the Rutan's interest in Earth. It turns out to be fairly mild.Fourth Doctor: Why invade an obscure planet like Earth? It's of no value to you.
Rutan: The planet is obscure, but its strategic position is sound.
- Sickly Green Glow
- Voluntary Shapeshifting: With great effort.
Movellans (Fourth Doctor and Twelfth Doctor)
- "We are infinitely superior."
- Achilles' Heel: The major weakness of the Movellan design was each android's external power pack which, being carried on their belts, was easily removed and completely shut down the android, not to mention they could easily be modified, reprogramming the android to obey human orders.
- Deceptively Human Robots: The Movellans outwardly resembled physically attractive Humans of various ethnicities and both genders. All of the Movellan androids wore white, form-fitting uniforms and their hair in silver braids resembling metallic dreadlocks. Being androids, the Movellans were stronger than humans. Because they do not wish to reveal their mechanical status to others, they do not allow aliens to see them in death, claiming such a thing would be against their code of honour.
- Long Bus Trip: Nobody was expecting them when they appeared in "The Pilot", 38 years after their last appearance.
- Plaguemaster: The Movellan Virus was developed by the Movellans to attack Dalek casings and tissue.
Nimons (Fourth Doctor)
Voiced by: Clifford Norgate (1979-80)
"THE NIMON BE PRAISED!"A race of parasitic nomads, the Nimons travel from planet to planet posing as gods to other civilizations. However, the Nimons eventually drain the planet of its life energy and move on to the next world. Their sole appearance on television is "The Horns of Nimon", but the Nimons also made a memorable appearance in Big Finish Doctor Who and were alluded to in the revived series episode "The God Complex".
- Evil Sounds Deep: They have deep, booming voices.
- Frickin' Laser Beams: Uniquely, the Nimons fire lasers out of their horns.
- God Guise: Their modus operandi when it comes to their invasion plans.
- Large Ham: "The Horns of Nimon" is so full of hammy acting it would offend Israel, and the Nimons themselves are no exception.
- Life Drain: How they feed. It leaves people, and entire planets, as desiccated husks.
- A Load of Bull: The Nimons greatly resemble the Minotaur of Greek myth.
- Milking the Giant Cow: The actors in the Nimon costumes are really going for it. Oh, and no jokes about "giant cows."
- Red and Black and Evil All Over: Black fur/skin with bright red eyes.
- Unrealistic Black Hole: The Nimons use black holes to power their technology and as wormholes to travel the universe.
Trions (Fifth Doctor)
Trions are an alien species that the Fifth Doctor's companion Turlough belongs to.
- Deep Cover Agent: According to Turlough, the Trions had undercover agents on every civilized planet, including Earth.
- Human Alien: Trions looked identical to humans and could survive in similar conditions. Since the nurse at Turlough's school had no problem when examining him, that would imply that Trions have similar, if not identical, internal structure to humans. Though based on Turlough's comments, he may be older than he looks, implying a different rate of ageing.
Eternals (Fifth Doctor)
Played by: Lynda Baron (Captain Wrack), Leee John (Mansell) Keith Barron (Captain Striker), Christopher Brown (Marriner) (1983)The Eternals were beings of immense power but limited creativity. They used the thoughts and emotions of so-called Ephemerals (their word for mortals) for their own ends.
- Blue and Orange Morality: The Eternals shown in "Enlightenment", like Striker and Marriner, simply do not understand human/Time Lord morality. Wrack is a bit more of a clearcut villain, but still has shades of this.
- Complete Immortality: The Eternals dwelt in the domain of Eternity rather than the smaller one of Time. This meant they were unaffected by Time and thus unaging. Another factor is that Eternals cannot be destroyed, only transferred back to Eternity. However, in the Doctor Who Magazine comic Uninvited Guest, the Seventh Doctor might have found a loophole.
- Eldritch Abomination: Exist outside of time and space in eternity, have great Reality Warper powers and they are to Time Lords what Time Lords are to other races.
- For the Evulz: As shown in the Doctor Who Magazine story Uninvited Guest, the more sadistic Eternals would sometimes pose as gods and doom whole worlds in the process.
- Screw This, I'm Out of Here!: Supplemental material states they left reality after the Time War and never came back.
- Sealed Evil in a Can: They were the ones who locked away the Carrionites.
- Telepathy: They could use telepathy and create objects from the memories of Ephemerals, but their powers were not limitless and they could not read minds from great distance or from strong minds (though Adrenaline from the mind they're accessing helps greatly).
- Who Wants to Live Forever?: Eternity is boring, so they have to find something to do to occupy their time.
Haemovores (Seventh Doctor)
A race of vampiric, aquatic creatures that served Fenric - they are implied to be the future descendants of Humanity, mutated by toxic slime into bloodthirsty abominations. They are also partially psychic, and can be telepathically repelled if enough faith is exhibited in close proximity to them.
- Bad Future: Humanity will apparently evolve into Haemovores if Fenric succeeds in conquering Earth in the 1940s. It's not clear whether this potential future has been averted by the end of "The Curse of Fenric".
- Frozen Fashion Sense: The sequences where the haemovores rise up to feast on the living display everything from Elizabethan doublets to eighteenth century seawool. Justified, as they've all been holed up since they were turned, and haven't exactly had a chance to nip down to the shops and pick up something more trendy.
- Holy Burns Evil: Haemovores can be repelled by faith itself. The Doctor repels them by repeating the names of all his companions, the fervently Communist Sorin repels them with a red star badge from his uniform, and Reverend Wainwright sadly fails to repel one using a bible, as the horrors of World War II destroyed his faith.
- Immune to Bullets: Bullets slow the Haemovores down, but can't kill them.
- Not Using the "Z" Word: The Doctor states that the Haemovores are not 'vampires'. Anyone to refer to them as such is immediately corrected.
- Our Vampires Are Different: Besides acting more like zombies than vampires, Haemovores can be blocked by a psychic barrier created by one's faith.
- Viral Transformation: How the Haemovores are created.
Revival Series Debut
The Gelth (Ninth Doctor)
A once organic, now-intangible race of aliens who have been left as refugees as a result of the Time War. As a result of their wraithlike forms, they have to depend upon possessing and inhabiting decomposing human corpses in order to survive to survive.
- False Innocence Trick: The Gelth claim to be refugees from the Great Time War who have lost their bodies and only want to use dead humans as Meat Suits. It turns out that there are many more of them than they claimed, and they want to take over all humanity, not just the dead ones. Granted, they're not actually lying — the key here is that they just need dead bodies. A few billion. Which means a majority (if not all) of the human population of Earth at the time.
- Invading Refugees: The Gelth were fleeing the Time War.
- Nightmare Face: Behold◊
- Not Using the "Z" Word: The Gelth aren't called ghosts in the story, which is fair enough since they aren't actually ghosts, just gas creatures. They can also possess human bodies for a little zombie action.
- Puppeteer Parasite: The Gelth.
- Red Eyes, Take Warning: You know the Gelth aren't what they claim when the one speaking through Gwyneth changes from a soothing uniform blue to having red eyes.
- Unfortunate Implications: This episode caused major controversy when first broadcast, as its depiction of the Gelth as malevolent conquerors posing as harmless refugees was considered to be a metaphorical echo of contemporary racist accusations against real-world immigrants to Britain.
The Slitheen familynote (Ninth Doctor)
Playednote by: Annette Badland, David Verrey, Rupert Vansittart, Eric Potts and Steve Spiers (2005)
"Victory should be naked!"The first recurring aliens original to the revitalized Doctor Who franchise, the Slitheen are basically a family of Used Car Dealers and Con Men. IN SPACE! Their family hails from the planet of Raxacoricofallapatorius, where most of the family has been sentenced to death for being rather annoying and kinda evil. Unlike most alien baddies, they're a crime family, not an Always Chaotic Evil species — the other Raxacoricofallapatorians are, according to the Doctor, rather peaceful. While they mainly only showed up during the Ninth Doctor's tenure (and an unidentified Raxacoricofallapatorian cameoing at the end of the Tenth's), the Slitheen also made it over to The Sarah Jane Adventures, where a rival family, the Blathereen, is often mentioned, and two Slitheen-Blathereen (orange-skinned Raxacoricofallapatorians) appear, along with a strange dark green-skinned Raxacoricofallapatorian. Perhaps the most unique feature about the Slitheen is their habit of skinning humans and using said skins as disguises.
— Jocrassa Fel-Fotch Passameer-Day Slitheen
- Affably Evil: They're only doing their business, after all, even if said business does involve destroying entire planets. Besides, hunting and killing are a trait of their species. They can't really help that, and they're pretty polite until you upset them.
- Always Chaotic Evil: Subverted-we're led to believe they're just another invading species, but they're actually a criminal syndicate. Raxacoricofallapatorians are rather peaceful.
- Becoming the Mask: Both Blon Fel-Fotch Passameer-Day Slitheen and her brother who impersonated Oliver Charles/Asquith appear to suffer from this. The former is horrified after she realised she's gone native after six months amongst the Welsh, while the latter regrets having to ditch his old skin suit, as he got to have "a wife, a mistress and a young farmer".
- Bizarre Alien Biology: They're made of calcium, able to smell fear and pheromones produced by humans, and can expel poison through their fingernails (via darts) or their breath. Due to their biochemistry, they also have a severe allergic reaction to vinegar.
- Costumes Change Your Size: Justified with their technology, allowing them to fit inside of their tinier human disguises.
- Cruel and Unusual Death: The reason Slitheen don't go home. Their method of execution involves them being lowered into a vat of acid, which causes their innards to fall out, while the Slitheen's still alive. Then the acidy-slitheeny soup is drunk afterward.
- Egomaniac Hunter: The Slitheen family, at least, enjoy hunting and treat it like a ritual.
- Even Evil Has Loved Ones: They're a crime family that legitimately cares about each other—after most of them are killed in their debut, Blon cries about her lost loved ones in a later episode.
- Evil Has a Bad Sense of Humor: They tend to act like evil, overgrown kids. Apart from the fart jokes, their idea of a fake alien is to take an ordinary pig, perform gruesome surgery on it and then stick it in a spaceship.
- Evil Plan: The family Slitheen seems to be rather good at vile schemes to enrich themselves. It's just that they don't count on the Doctor showing up, or Sarah Jane Smith.
- Exposed Extraterrestrials: When they're not in their human suits. Lampshaded with dialogue about it being traditional to hunt naked.
- Face Stealer: Along with the rest of your skin.
- The Family That Slays Together
- Fat Bastard: In their human disguises, as the eight-foot-tall Slitheen have to use the skins of overweight people for disguises.
- Gasshole: Not naturally, but squeezing into their human disguises requires a "gas exchange" that results in this.
- Hannibal Lecture: Margaret / Blon in "Boom Town" while trapped in the TARDIS, tries to guilt the heroes into releasing her. Jack says not to answer back, "... it's what she wants."
- Hunting the Most Dangerous Game: The Slitheen family at least, really like hunting humans.
- Kill and Replace:Doctor: You're pleading for mercy out of a dead woman's lips.
- Only Known by Their Nickname: Members of their species are often referred to as "Slitheen", after the infamous crime family that hails from Raxacoricofallapatorius. The Doctor mentions that the other members of the species are peaceful and implies they're somewhat irritated by the Slitheen sullying their good name, which might explain why all the Slitheen family have been been sentenced to death on their homeworld.
- Overly Long Name: Raxacoricofallapatorius.
- Rogues-Gallery Transplant: After being introduced in the first season of the revival series, the Slitheen effectively migrated to The Sarah Jane Adventures, making more appearances there than in the show that birthed them.
- Toilet Humor: The best way to spot a disguised Slitheen? They fart. A lot.
- Weaksauce Weakness: Vinegar. Go figure.
Roboforms (Tenth and Eleventh Doctors)
Played by: Paul Kasey (2005–06), George Cottle (2005)Roboforms were scavengers who travelled alongside invaders who took anything on the planet of value to them before the main threat arrived. They seemed especially prone to attacks on Christmas, dressing up as killer Santas whose presence became the "pilot fish" that precluded another holiday season down the tubes. Due to their heavily robotic biology, they could be reprogrammed and manipulated by a remote signal for use as minions.
- Bad Santa: A whole brass band of them, complete with weaponized instruments.
- The Cameo: In "The Pandorica Opens", in their non-Santa forms.
- Instrument of Murder: The Roboform wield brass instruments that double as weapons, including a trombone-flamethrower.
- Robotic Reveal: Once the mask comes off.
- Lesser of Two Evils: They're just scavengers who travel alongside the real threat.
Sycorax (Tenth and Eleventh Doctors)
Played by: Sean Gilder (2005)The Sycorax were a superstitious race of warriors. They often wear skeletal masks, with equally skeletal faces underneath.
"SYCORAX STRONG. SYCORAX MIGHTY. SYCORAX ROCK!" note
- The Cameo: In "The End of Time", "The Pandorica Opens", "The God Complex" and "The Magician's Apprentice".
- Duel to the Death: They believe in solving disputes by honourable combat, often to the death. The Sycorax Leader however violates this by attacking the Doctor even after he wins the fight and spares his life, leading to the Doctor triggering a nearby trap door that sends him plummeting to his death. Apparently the other Sycorax felt this either satisfied honour or didn't want to test the Doctor's patience, since they left shortly afterwards.
- Heel–Face Door-Slam: After being beaten by the Doctor, the Human race take the opportunity to fire upon them as they're peacefully leaving Earth, vaporising the entire asteroid.
- Historical In-Joke: The Doctor feeding Shakespeare his own lines. Specifically, it resolves the Brick Joke of the Sycorax set up in "The Christmas Invasion"; Sycorax is a witch mentioned in The Tempest, and where Shakespeare got the name is a bit of an academic mystery — as far as anyone can find she's not a figure from mythology, and if it's a Meaningful Name it's far from obvious what the meaning is. "The Christmas Invasion" used it as the name of an alien species, with no explanation/comment, and this episode has Shakespeare hear the Doctor talking about them and likes the sound of it.
- Insufficiently Advanced Alien: Not touched upon much, but they seem to believe in witchcraft and curses (it's how they describe the Doctor's regeneration). One can only guess what they think of Carrionites.
- Planet Spaceship: The Sycorax come from an asteroid named Fire Trap, which was retrofitted into a starship when one fell upon its surface. They eventually built an entire Armarda out of captured and colonised asteroids.
- Proud Warrior Race Guy: They believe in solving disputes with a Duel to the Death.
Catkind (Tenth, Eleventh and Twelfth Doctors)
A species of humanoid aliens which resemble felines, who hail from a planet called New Savannah. The Catkind first appear as an order of nuns called The Sisters of Plentitude in "New Earth" A subspecies called Leonians antagonises Ashildr and the Twelfth Doctor in "The Woman Who Lived."
- Cat Folk
- Cute Kitten: What the babies of this species resemble.
- Dominant Species Genes: A Catman and human female husband and wife produces litter of kitten offspring.
- Female Feline, Male Mutt: Ultimately averted. Although the first Catkind we meet are unanimously female, this is because Rose and the Tenth Doctor have visited a convent. Later on the Doctor meets male members of the same species.
- Saintly Church: The Sisterhood run a hospital founded by charity to heal the sick.
Clockwork Droids (Tenth and Twelfth Doctors)
- "We did not have the parts."
- Admiring the Abomination: The Tenth Doctor openly admits they're beautiful, before quickly adding that it's not going to stop him breaking them.
- A.I. Is a Crapshoot: These droids seem overly literal. When the crew of SS Madame de Pompadour instructed the robots to repair the ship, they did not anticipate that they'd have to tell the droids that they could not use the crew as spare parts.
- Alas, Poor Villain: When the Pompadour droids shut themselves off after they realise there's no way back to their ship, it's quite poignant. They were just following their programming, after all.The Doctor: How many ticks left in that clockwork heart?
- Awesome Anachronistic Apparel: The droids wear swanky outfits to blend in with the periods they time-travel to. Out of universe, it also hides their mechanics, saves money for the effects budget, and allows them to wear their disturbing masks
- Blade Below the Shoulder
- Clock Punk
- Clockwork Creature: They're literally wind-up droids powered by clockwork, and have a distinct ticking sound when they move.
- Costume Porn: The SS Madame de Pompadour droids are possibly the best dressed Doctor Who villains ever.
- Creepy Monotone
- The Croc Is Ticking: A literal ticking sound signals their presence.
- Driven to Suicide: In their first appearance the droids simply give up when they realise they can't return to their ship. The Half Face Man may have jumped to his death in a crisis of faith, or the Doctor may have simply pushed him.
- Emergent Human: The Half Face Man is rapidly approaching this state.
- Face Stealer: In "Deep Breath".
- Gone Horribly Right: The SS Madame de Pompadour was nearly wholly repaired, though the crew did not live to see it.
- Gorgeous Period Dress: In 18th century France.
- Grew Beyond Their Programming: The Half Face Man gained emotions and even faith due to the sheer amount of human parts he replaced himself with.
- Human Resources / Organ Theft: No one told them they weren't allowed to use human parts.
- Humanity Ensues: The Half Face Man gains faith (in the Promised Land), appreciation of beauty, anger and perhaps even depression in his conversion to a semi-organic state.
- Insane Troll Logic: The whole reason the ones from the S.S. De Pompadour went after their namesake, smashing holes through time to get there. They believed that her brain was what was needed to repair their ship, and specifically her brain when she was the same age as the ship. Using the time-windows to get back to Earth their time and fetch help apparently never occurred to them.
- Just Following Orders: The crew of the SS Madame de Pompadour.
- Kill It with Fire: How the Half Face Man hides his actions, destroying everyone it steals from with vast amounts of fire.
- Literal-Minded: An incredible design flaw. For example, the droids aboard the SS Madame de Pompadour believed that only the brain of the ship's namesake would serve as a replacement for the ship's computer.
- When a man called Alfie talks with the Half Face Man and mentions his eyes are his "greatest gift", Half Face Man assumes he's offering them as a gift. Eye Scream quickly follows.
- Malevolent Masked Men: Only when in 18th century France. When stuck in Victorian London, the droids flay their victims and wear their faces.
- Marionette Motion: Both variants move with stiff, unnatural motions.
- Obliviously Evil: The droids are incapable of perceiving the life of a human as more valuable than a box of machine parts, apparently as they were not programmed with it.
- Paper-Thin Disguise: The Madame De Pompadour droids are especially bad about this. Intending to hide in pre-Revolutionary France, they don the appropriate disguises, which are completely undone by their Machine Monotone voices, stiff and jerky movements, and the constant ticking, clicking and whirring that follows their every movement.
- Perpetual Smiler: In their masquerade masks.
- Ragnarök Proofing: If the Half Face Man is accurate, he's been working at repairing his ship for several hundred million years, and is still expecting it to fly.
- Slasher Smile: The Pompadour droids wore creepy, smiling masks.
- Theme Naming: The ships the clockwork droids work for are named after famous women from history.
- Three-Laws Compliant: Horribly averted. The Droids follow Rules 2 and 3 (obeying the orders of humans and preserving their own existence, respectively) while ignoring Rule 1.
- Walking Transplant: Not them, but everyone else is fair game, even a T-Rex isn't safe.
- Wetware CPU: Why Reinette was the target of a kidnapping.
- Would Hurt a Child: Averted with the Pompadour droids, if only because little Reinette wasn't "compatible". Inferred with the Antoinette droids, what with that remark about the "children's menu".
Ood (Tenth and Eleventh Doctors)
Voiced by: Silas Carson (200610, 2012)A race of telepathic humanoids native to the Ood Sphere (which is in the same region of space as the Sense Sphere). They were used as slaves during the Second Great and Bountiful Human Empire, until they were liberated by the Doctor, Donna and a spy for the Friends of the Ood.
"The circle must be broken, so that we can sing."
- Bizarre Alien Biology: They're born with secondary brains in their hands. The company that enslaved them cuts them off to make them docile.
- Cthulhumanoid: A mass of tentacle like appendages hanging from where mouths should be.
- Dark Is Not Evil: Zigzagged. Despite their monstrous appearance, the Ood are peaceful and gentle. However, they wind up taking an antagonistic role in almost every appearance. A large part of the problem is that their hive mind leaves them open to Demonic Possession.
- Happiness in Slavery: Via lobotomy.
- Hive Mind: Governed by a large living brain situated on their planet called the "Ood Brain", without it the Ood would die.
- Perfect Pacifist People: They are naturally a peaceful race, which is why the humans chose to turn them into a Slave Race.
- Red Eyes, Take Warning: When they were controlled by the Beast. And later again when the Ood Brain managed to reach out and make the Ood take revenge against their human captors.
- Shout-Out: Russell T Davies has acknowledged the Sensorites as an influence on the basic concept of the Ood in "The Impossible Planet" and "The Satan Pit". Computer read-outs (and a mention by Davies in an episode commentary) revealed that the Ood Sphere and Sense Sphere are part of the same star system.
- Also Mind Flayers — aside from their appearance, the flayers eat brains (the Ood vomit one of theirs forward upon maturing), and both serve an Elder Brain.
- Slave Race
- Weak-Willed: In addition to their status as Slave Race, the Ood seem to be particularly susceptible to possession by outside entities.
- Explained by Donna Noble and confirmed by the Doctor that it's due to the fact that they're born with their brains in their hands. With such a glaring evolutionary weakness, they have no choice but to trust everything simply as a survival mechanism.
- We Will Use Manual Labor in the Future
Judoon (Tenth and Eleventh Doctors)
Voiced by: Nicholas Briggs (2007–10)The law enforcement arm of the Shadow Proclamation, Judoons look like bipedal rhinos in Badass Biker gear. They are extremely fond of rules and regulations, as seen in The Sarah Jane Adventures, and a bit thick.
"FO! SHO! RO! KO! BLO!"
- Badass Biker: Just the outfits, not the rebellion.
- By-the-Book Cop: Played with; although the Judoon strictly obey the letter of the law, their "book" allows for a lot of Cowboy Cop or even Knight Templar behavior on their part.
- Disproportionate Retribution: Strike a Judoon? Sentence: execution, by means of disintegration. Interfere with its interplanetary police work? Expect the same. Live on the same planet where a mass-murdering criminal has taken refuge? Your whole blasted planet gets destroyed if the Judoon haven't been instructed to recognize you as a species worth protecting.
- The Dragon: As a whole, for the Shadow Proclamation.
- Lawful Stupid: The Judoon have an almost one-track sense of justice. They will execute anything and everything for the slightest offense, no matter if they're lashing out because they feel cornered, an alien criminal, or just in the way. But if you get on their good side, they might simply ground you from space travel.
- Guttural Growler
- Hell-Bent for Leather
- Judge, Jury, and Executioner: "Justice is swift."
- Law Enforcement, Inc.: Their hat.
- Perpetual Frowner: Their faces seem set in this expression.
- Rhino Rampage: Alien rhinos, and are naturally depicted as burly and aggressive.
- Space Police: Or police-for-hire, as the Doctor puts it.
- Trigger Happy: especially in The Sarah Jane Adventures.
Weeping Angels (Tenth, Eleventh and Twelfth Doctors)
"In the sight of any living thing they literally turn to stone. And you can't kill a stone. 'Course, a stone can't kill you either, but then you turn your head away. Then you blink, and oh, yes it can!"Quantum-locked creatures so ancient, even the Doctor doesn't know where they come from. As long as they are being observed, the Angels turn to stone. The "Weeping" in their name comes from their habit of holding their hands over their eyes so as not to accidentally see each other. As soon as they are unobserved, they move with Super Speed to overtake their prey. For nourishment, they'll transport their victims back through time and then feed on their lives spent in the past. If they're not feeling hungry, though, they'll just snap their victim's neck like a twig. One of the creepiest aliens in the history of the series.
— Tenth Doctor
- Abstract Eater: They feed on time energy, sending people back in time and consume all the years they would have lived in the present.
- Always Chaotic Evil: Though their usual method of "killing" isn't all that bad, they only employ it because that is how they feed. In their second appearance they find another, better source of nourishment... since they don't need food they proceed to act like the sadistic psychopaths that they are—snapping necks, playing mind games, and ripping out vocal cords. Why?Angel Bob: For fun, sir.
- Possibly averted by the lone angel at the end of The Angels Take Manhattan, who sent Amy back in time to the same point as Rory when it could've easily done otherwise.
- Ambiguous Gender: While this is rather appropriate for an angelic being, it only serves to increase the Uncanny Valley for these.
- And I Must Scream: Angels cannot look at themselves or other Angels, because it triggers their quantum-locking functions. As long as nothing disrupts the line of sight of an Angel that has suffered the misfortune of locking eyes with a mirror or its bretheren, they will remain stone permanently. Well, at least until they starve to death and corrode into dust.
- Astonishingly Appropriate Appearance: At first glance, they appear to be statues that would be seen in a cemetery. Look away, and it's your funeral.
- Bizarre Alien Biology: Creatures of the abstract. They turn to stone when anyone is looking. Ultimate defense mechanism.
- Breakout Villain: They're to the revived show what the Daleks were to the classic show. They actually beat the Daleks as the fan's scariest monster in a poll, and get a lot of appearances outside their own story arc.
- Creepy Changing Painting: More accurately a Creepy Changing Statue. The painting applies as well, as anything that bears the image of Angel becomes an Angel itself. Amy finds this out with the recording of an Angel.
- Eldritch Abomination: It is implied that they are, in fact, sapient ideas which have come to life to kill people. It helps that ideas of them (photos, visual memory) literally can come to life to kill people.
- Enfante Terrible: Baby Weeping Angels appear to be innocent cherubs statues at first glance, but turn away and they will reveal gruesome looking fangs just like their full-grown counterparts. They haven't developed enough strength to send victims very far into the past, but often appear in clusters. They're also audible before attacking- you can hear their footsteps and creepy laughter - which may make them more frightening than the adults. Worse yet, the cherubs are a lot smaller and harder to keep an eye on if you're a fairly tall person.
- Everything Trying to Kill You: The implication at the end of "Blink" was any statue is a potential Angel. "Time of the Angels" had the Byzantium fall of statues which were all possible Angels, until eventually it's revealed all of them were Angels. Then in "The Angels Take Manhattan", every statue in existence was an Angel, including the freaking Statue of Liberty.
- Evil Laugh: Is not even recognizable as laughter, so much as horrible screeching. However, the baby cherubs have a very distinct, terrifying giggle, often accompanied by pitter-pattering footsteps as they rush their prey while their back is turned.
- Fangs Are Evil: They show off fangs as they rush in to attack.
- Faux Affably Evil: Sending people to live in the past, though not all bad, is only a circumstantial side effect of how they feed. If they aren't desperate for energy, they'll just violently snap your neck and enjoy it too.
- Femme Fatalons: The angels are genderless but their statue forms may look feminine and they certainly have claws which, if you are lucky enough, you might see reaching out for you.
- Fate Worse Than Death: Not in their first appearance, where they "kill you nicely" and get enthusiastic testimonials from their victims. It's played dead straight in their second, where while they kill most of their victims and they partially reanimate Sacred Bob into a mouthpiece for the Angels. In their third, they keep humans in solitary confinement for their whole lives while repeatedly sending them back into the past to feed.
- For the Evulz: The reason they give for making Amy Pond count down to her own death is "for fun, sir".
- The Fourth Wall Will Not Protect You: Part of what makes the Weeping Angels so terrifying to viewers was the implication that the audience counted as an observer when determining when the angels can or can't move, as the Angels could often be seen quantum-locked when only the viewer was watching them. Averted later in "Flesh and Stone", but un-averted in "Angels Take Manhattan".
- Generic Doomsday Villain: They are a case of this trope working their favor. The fact that on top the sheer Nightmare Fuel that's already associated with them means that the fact they are nothing more than psychopaths that will murder because they can makes them all the more terrifying.
- Healing Factor: As they starve they will deteriorate in appearance, but give them a source of food (energy) and they'll be back to their traditional angelic appearance in hours.
- Hoist by His Own Petard:
- In their first appearance, the Doctor tricks them into looking at each other, freezing them forever.
- In their second appearance, they try to draw energy from one of the omnipresent 'cracks in the universe' to become a universe-devouring army of death. This backfires badly on them. The crack is 'the end of the universe' and releases time energy which wipes anything it consumes out of existence. They drain all of the power from the ship to try and escape... which switches off the artificial gravity, resulting in them all being hurled into the crack and erased from time. That is, until the universe was rebooted, allowing for their return.
- Humanoid Abomination: Their "quantum locked forms" look like human statues, until you look away and the abomination comes forth.
- Implacable Man: An Angel will never stop hunting a victim when they have their eyes set on them. They're near impossible to kill, and little can keep them out or slow them down for good.
- Kick the Dog: Angels will taunt and torment anyone and anything that looks delectable. In the case of the babies, it's Poke the Poodle, since they can't do as much harm.
- Light-Flicker Teleportation: They will advance in the instance of darkness, as their quantum lock has subsided. It's made even more prevalent that they can move at very high speeds.
- Light Is Not Good: Angelic in appearance, demonic in nature. As of "Angels Take Manhattan": they can be anything... including cherubs with creepy laughs and bronze statues in parks... and the freaking Statue of Liberty!
- Living Statue: Subverted. While they certainly seem like this, they only appear as statues under observation. Since this makes it impossible to see them move, many would assume they're statues themselves.
- Made of Iron: Though the obvious logic would just be to smash them into dust as stone statues, they are a lot tougher than statues should be. A group of soldiers unloading on them doesn't even scratch them. It's somewhat justified in this case. It was a dark hallway and the muzzle flash from the bullet was lighting them up, meaning they were stone when the bullets struck them. The split second of darkness between shots caused them to revert to their natural form, then reform back into unblemished stone when the next flash occurred. Their natural defense mechanism can therefore double as a rather effective Healing Factor. Then we get to see their true form is very stone like as well, so they're immensely tough all the time. As the Doctor says, "You can't kill a stone".
- Mysterious Past: No one quite knows where they came from, including the Time Lords. "The Time of Angels" implies they were an idea that took on a life of its own.
- Neck Snap:
- Normally, the Weeping Angels kill by sending victims back in time and feeding on their residual energy... but should they not need to feed on a person's temporal energy... crack goes their neck. They have very strong clamping force that makes it near impossible to escape their grip. If an unlucky soul gets caught, they're either dead, or doomed to a struggle that will likely tear up their body.
- Worse, Angels like to play with their food and steal the consciousness of a person they killed, then steal the voice of the deceased and use it to lure others into a false sense of security, until they get to break their necks as well.
- New Powers as the Plot Demands: Each episode starring them adds new abilities, while sometimes ignoring their existing limitations.
- In "The Time of Angels" and "Flesh and Stone", we learn in addition to having straightforward Offscreen Teleportation powers, the image of an Angel becomes an Angel, looking one in the eyes can cause a new Angel to grow in one's mind, and the Angels can partially reanimate a dead person to be their "voice". Somewhat justified in that the Angels in "Blink" were starving while these Angels are slowly feeding off the crashed ship and getting stronger, but the abilities still come a bit out of left field.
- In "The Angels Take Manhattan", The Statue of Liberty becomes a Weeping Angel. This seemingly means that any statue, even ones made of copper, can become a Weeping Angel when before it was explicit they weren't literally statues that came to life, just quantum locked creatures that looked like statues. Although in their debut episode, the ending did imply that every statue was at risk of being a Weeping Angel. It's also not clear how "the image of an Angel becomes an Angel" rule applies to all the post cards and other images of the Statue of Liberty.
- Averted in "The Time of the Doctor", where from what we see they have their traditional powers.
- Nightmare Face: They look very Uncanny Valley up until the point when they prepare to feed on someone's temporal energy- that's when they sprout monstrous fangs and bare a set of claws at their target.
- Nobody Here but Us Statues: They don't hide as statues deliberately; they just happen to look like them when quantum locked. Nevertheless, it is effective camouflage against the unweary.
- Offscreen Teleportation: Their explicit super-power, although it's more of a restriction, as they cannot move while someone is looking at them.
- Only Known by Their Nickname: They're called "weeping angels" because they happen to look like them; they're actually hiding their eyes to prevent staring each other in the eyes. The actual name of the species, if there is one, is unknown.
- Our Gargoyles Rock: They're not gargoyles but their statue forms appear to be them in the right location.
- Reality Warper: A minor example: there are limitations to what they can do, but they can defy several laws of physics.
- Scare Chord: Their Leitmotif.
- Slasher Smile: If an Angel knows victory is at hand and its victims have no chance of escape, it flashes a horribly malicious grin at them.
- Staring Contest: One where the consequence of losing is death.Tenth Doctor: Don't blink. Blink and you're dead. Don't turn your back. Don't look away. And don't blink.
- Step into the Blinding Fight: Justified; they become 'quantum-locked' and completely incapable of moving when being observed by other living things, so they've developed abilities that let them drain power from light sources when in statue-form, making it easier to approach their prey. Unfortunately, the darkness doesn't hinder their vision at all.
- Stupid Evil: All angels are sociopaths, but even knowing who the Doctor is they'll go out of their way to piss him off for no reason other than to be a dick. They don't seem to understand that this might not be the best idea.
- Super Speed: They need only the time it takes to blink to dart forward and slay their victim.
- Taken for Granite: Whatever they are in their natural state, they turn to stone if looked upon. It seems they're like the Nestene, in that while anything plastic can be a Nestene, any statue can be an Angel; this was hinted at in the Paranoia Fuel last terrifying minute and a half of "Blink" and outright confirmed in their third appearance.
- Time Abyss: They're as old as the universe, or very nearly. Rassilon himself calls them "the Weeping Angels of old."
- Voice for the Voiceless: The Angels have no voices of their own... but they can tear bits of consciousness from a victim they murder and make it speak on their behalf.
Toclafane (Tenth Doctor)
In the year ten trillion, when the universe is finally ending, The Master manages to trick the last vestiges of humanity into escaping to Utopia, where they are forcibly turned into The Toclafane. Named after creatures from a Gallifreyan fairy tale, the humans of the far future have been twisted into psychopathic cyborgs with the minds of children; integrated into spherical, mechanical shells. The Master used them as muscle when staging his invasion of Earth during "The Year That Never Was."
- Children Are Innocent: Averted. The Toclafane display childish personalities and speech patterns, but they are psychotic, sadistic and callous, even when fighting their own ancestors.
- Cybernetics Eat Your Soul: They mutilated themselves into their current state and are willing to kill off their ancestors.
- Cyborg: They are human heads encased inside robotic spheres.
- For the Evulz:Martha: But why? Why come all this way just to cause all this death and destruction?
Toclafane: Because it's FUN!
- Grandfather Paradox: The Master's Paradox Machine allows the Toclafane to freely murder their own ancestors without worrying about this. When it's destroyed, the timeline corrects itself.
- Human All Along: The Toclafane turn out to be the humans from the far future in "Utopia".
- Humans Are the Real Monsters: The Toclafane are the future of humanity, who turned themselves into cyborg Psychopathic Manchildren in a desperate attempt to survive the collapse of reality. Why are they slaughtering their own species? Simply because it's fun.
- Madness Mantra:The Toclafane: We shall fly and blaze and slice! We shall fly and blaze and slice!
- Same Story, Different Names: The Toclafane's origin story mirrors that of the classic Cybermen in "The Tenth Planet". In that episode, the Earth's lost "sister planet" of Mondas returns along with humanity's evolved cousins, who turn out to be metallic fossils of their former selves. Those events prove too much for the First Doctor, who dies of exhaustion. Ten fares a little better here, though he still ages a lot, and his faith in humanity is once again shaken.
- Transhuman: The last generation of humanity transformed into cybernetic spheres.
Adipose (Tenth Doctor)
A friendly race of marshmallow-like blob creatures that appeared primarily in "Partners In Crime", created from living fat.
- Baby Talk: A justified example, as in their debut they were babies.
- Blob Monster: In the words of Matron Cofelia "the fat just 'walks away'."
- Children Are Innocent: Pointed out by the Doctor, to Donna. Being newborns, they're not responsible for the methods Matron Cofelia used to bring them into the world.
- Ridiculously Cute Critter: Baby Adipose look like plush toys.
- Powered by a Forsaken Child: When they are created via emergency parthenogenesis, the person they come from dissolves into Adipose and dies. This is not their fault, but rather the fault of their "foster mother".
- Mascot Mook: The Adipose are the mascot of the official Doctor Who tumblr blog, mostly due to how incredibly cute and huggable they are.
- The Worm That Walks:
- In "Partners In Crime", they would be born when the fat of a taker of an Adipose pill dissolved into a swarm of them.
- Used in a darker vein in "Turn Left", when in the altered timeline, millions of Americans were dissolved to create them.
Hath (Tenth and Twelfth Doctor)
Bizarre looking, man sized fish people. First encountered as a clone army by the Tenth Doctor.
Vashta Nerada (Tenth Doctor)
- "These are our forests. They are our meat."
- Broken Record: Someone consumed by a Vashta Nerada will have their neural chip "ghosting" and repeating the same phrase on a loop.Proper Dave: Hey who turned out the lights? Hey who turned out the lights?
- The Croc Is Ticking: You can tell that a swarm of Vashta Nerada has eaten someone when the microphone starts acting like a Broken Record and repeats the same phrase over and over.
- Darkness Equals Death: If you enter a shadow that the Vashta Nerada occupies, you will be devoured.
- Dark Is Evil: Living Shadows that devour humans and strip them to the bone.
- It Can Think: They are very quick learners. When one of the group is eaten, they hijack the suit and project more shadows around them, turning it into an "Instant Death" Radius, in order to increase their hunting capabilities. Then they start to tweak the suit's data ghost to speak and learn how to do so fluently within the next few hours at most.
- Living Shadow: A swarm of Vashta Nerada looks like a dark shadow moving across the ground. They can even form the shape of a humanoid of shadow to animate spacesuits.
- Primal Fear: The species is implied to be the reason that many species have a natural fear of the dark.
- Stripped to the Bone: When they devour humans and a chicken leg, all they leave are bare bones.
- The Swarm: They're thousands of microscopic carnivores working in unison.
- Zombie Gait: It's not like space suits are designed to be piloted by swarms of thousands of miniscule creatures that ate the previous occupant.
The Atraxi (Eleventh Doctor)
A cosmic police force of flying crystalline aliens, who are also the wardens of an inter-dimensional prison. They track down escaped convicts and terminate them with extreme prejudice ... unfortunately "extreme prejudice" means that they're willing to destroy an entire planet to eliminate their quarry.
- Canon Immigrant: The planet Atraxi 3 is first mentioned in the Eighth Doctor Adventures novel "Vampire Science."
- Do Not Adjust Your Set: The Atraxi are capable of hijacking every transmission on every TV and radio channel on Earth in their search for the escaped Prisoner Zero.
- Faceless Eye: Giant flying eyeballs surrounded by a crystal snowflake.
- Giant Eye of Doom: They're nothing but the eye.
- Kill It with Fire: How the Atraxi intend to deal with Prisoner Zero and the human "residence."
- Oculo Thorax: The Atraxi are a Giant Eye of Doom that can fly through outer space.
- Space Police: Even more alien and more callous than the Judoon. They were prepared to torch an entire planet just to make sure Prisoner Zero didn't escape.
- Starfish Aliens: The Atraxi, putting the "alien" in "alien police" with their big eyeballs and crystalline web ships.
The Silent Priests (Eleventh Doctor)
Played by: Marnix Van Den Broeke (2011)The faces (creepy, creepy faces) of a religious order called "the Order of the Silence", the Big Bads of the Eleventh Doctor's run. The Order itself is comprised of a much larger collection of races, but the Priests are the main attraction: in the same vein as the Weeping Angels, you're never safe if you're not looking at the Silence, but for a different reason: as soon as you look away from a Silent Priest, you forget you ever saw it.
Voiced by: Barnaby Edwards (2011)
Voiced by: Barnaby Edwards (2011)
"Silence will fall."
- Alien Invasion: The invasion is long over (at least in an alternate reality anyway). They've been controlling the planet for the last 10,000 years.
- Amnesia Danger: They cause it due to a function in their biology. As soon as you look away, you forget they're nearby.
- Badass Boast: In "Day of the Moon" and immediately subverted when the Silent saying it gets shot just to prove him wrong.Silent: This world is ours. We have ruled it since the wheel and the fire. We have no need of weapons.
- Back for the Finale: They appeared in the Eleventh Doctor's last episode, after not appearing for over two years.
- Badass in a Nice Suit: They wear nightmarish versions of stylish black and white business suits.
- Big Bad: The Kovarian Chapter functions as this for Series 5 & 6. They indirectly caused the majority of problems in series 5 & 6, even though they didn't make their on-screen debut until the premiere of series 6.
- The Blank: They have two prominent eyes, but that's it. They otherwise lack other familiar facial features like a nose, mouth, or ears.
- Breakout Villain: Along with the Weeping Angels, they are the revival series most popular villains.
- Catch-Phrase: Silence will fall, almost serves as the Arc Words.
- Ceiling Cling: They sleep hanging upside down. In packs.
- Church Militant:
- Part of the religious organisation, "the Order of the Silence".
- "Time of the Doctor" reveals that they were originally genetically engineered by the Papal Mainframe to serve as the perfect confessional priests, allowing people to confess their deepest sins and immediately forget about doing it. The ones the Doctor has been fighting are part of a Renegade Splinter Faction, attempting to alter history to prevent him ever reaching Trenzalore.
- Creepy Good: "The Time of the Doctor" reveals that the race, as a whole, are supposed to be the ultimate form of confessional privacy. They are servants of the Papal Mainframe and act in their interests, aside from the Renegade Splinter Faction. They just look scary.
- Dress-Coded for Your Convenience: Evil Silences wear ties, Good Silence wear collars.
- Evil Sounds Deep: Talk in creepy, raspy voices.
- Four-Fingered Hands: They have large four spatula fingers, with one large one used to discharge electricity.
- Gambit Roulette: Their plans to kill the Doctor are always incredibly convoluted and extreme. But given who they're dealing with... you can kinda understand.
- Their initial plan involves using post hypnotic suggestion and subterfuge to convince all the Doctor's enemies that he will destroy the universe, and to stop him they have to build the ultimate prison, the Pandorica. They also set it up so this ultimate prison will have a restoration field that will stop anyone in the prison from dying, and also happens to be a way to restart the universe if it should be destroyed. They then use a lower level time machine to sneak a member of their race aboard the TARDIS, wait till the Doctor has been sealed in the Pandorica, and then proceed to destroy the universe by blowing up the TARDIS. At this point they expect the Doctor to use the Pandorica and the exploding TARDIS to reboot the universe, which will save everyone but trap him in the void between realities in the process. And if any part of this plan hadn't worked, they'd have blown up the entire universe for good, the exact thing they're trying to kill the Doctor to prevent. Unfortunately for their planning, the Doctor ends up using some interesting Clap Your Hands If You Believe magic from his Touched by Vorlons companion to escape.
- Their second plan involves stealing one of the Doctor's companions and her unborn child, then replacing the companion with a programmable flesh avatar to prevent the Doctor from realizing the kidnapping. After that they begin genetically modifying the unborn child, who was conceived on the TARDIS, to be a human Time Lord (as opposed to a Galifreyan one). Then, after first surviving an assault by the Doctor himself to save the child when it's born, they transport her from the far future to 1960s America, where they used post hypnotic suggestion again to cause the moon landing. This is so the humans develop a space suit they can use to keep the child healthy and alive, and they can train her to kill the Doctor. Then, after the child manages to escape, and decides she doesn't want to kill the Doctor, and then saves his life, they keep tabs on her for several thousand years (thanks to her time traveling with the Doctor). At which point, they wait till she graduates from university to put her back in the space suit they developed in the 1960s, time travel her back to 2011 Utah, and put the suit on auto-pilot to force her to shoot the Doctor when he arrives there. Along the way the Silence are nearly wiped out by the Doctor and end up creating another universe ending time paradox when the child tries to resist shooting the Doctor. And after all that, the Doctor uses a fairly simple Tricked Out Time gambit to survive getting shot.
- Glass Cannon: They can easily disintegrate people, break through thick glass and heavy doors, but they can be killed fairly easily through conventional means.
- The Greys: According to Word of God, the idea is that stories of alien abduction by The Greys, among other things, represent half-retained memories of the Silence when on occasion people don't quite forget everything.
- Good Shepherd: It is revealed in Time of the Doctor that they are genetically modified priests, and their amnesia aura is intended to make them ideal to confess to.
- Hidden Agenda Villain: Despite being around since series 5, it's only in the final episode of series 7 the The Kovarian Chapter's full motivations are revealed: They wanted the Doctor dead before he potentially summoned Gallifrey back into our universe on the planet Trenzalore, an act that could have re-sparked the Time War.
- Hoist by His Own Petard: The Doctor drives them off Earth by tricking one of their own into ordering the entire human race to kill them on sight. An untold number of them on Earth end up dead because they tried to kill the Doctor, and if they hadn't made plans to kill him, he wouldn't have even known they existed.
- Kick the Dog: The first time we get a real scene with a Silent, it blasts a woman to death in front of Amy for no real reason, providing this little pleasant exchange.Amy: Why did you kill her?
Silent: Joy. Her name was Joy.
- Laser-Guided Amnesia: Their power is to make people forget the moments with them.
- Leaning on the Fourth Wall: 95% of the time when a character interacts with a Silent and then forgets about it, it's not shown; the scene we see continues abruptly from immediately before to immediately after.
- The Men in Black: According to Word of God, one of the inspirations for them. Hence the black suits and memory damage.
- Mundane Utility: Their terrifying ability that any person who sees them forgets they saw them as soon as the person turns away? Turns out that they're confessional priests and the original purpose of the ability was a way of preserving the privacy of the confession.
- Nice Job Breaking It, Hero!: Not exactly heroes, but their ultimate goal is to prevent the Doctor from ever reaching Trenzalore and speaking his name, as that will cause the Time Lords to come back and the Time War to resume, devastating the universe. Their first plan has the side effect of destroying the entire universe apart from the Earth, their second one fails and destroys the linear nature of time—hardly different outcomes from the ones they were trying to prevent in the first place.
- Nightmare FaceAmy: You're ugly. Has anyone ever told you that?
- No Mouth: Although a hole reminiscent of The Scream, where their mouth should be, forms when they discharge electricity.
- The Noseless: They appear to have nostrils, but no definable nose.
- Oh, Crap!: Upon realizing that the Doctor just turned their own tactics against them, and now all humans are going to start killing them on sight.
- Omnicidal Maniac: They're the ones responsible for destroying the TARDIS and the universe on June 26, 2010. Silence will fall. Let's put this into perspective. If you make the Daleks try to prevent your victory, you've earned the title.
- Only Known by Their Nickname: "The Silence" is the name of their Religion of Evil, rather than the species. It's a moot point because even if they were willing to tell people their real name, they'd forget about it as soon as they turned away.
- Outside-Context Problem: The Doctor hadn't even heard of these things before they came after him (at least as far as he can remember).
- Paranoia Fuel: Acknowledged in-universe. Their unique ability means that they generate this constantly in those who confront them, since as soon as you stop looking at them, you forget if you are in the room with them. Suddenly noticing a lot of tally marks on your skin is a good reason to panic.
- Psychological Horror: The scariest part about them is how they can be within close range without knowing, and the only sign they're close are tally-marks written on your arms.
- Religion of Evil: Subverted. They are briefly presented as such, but they actually consider themselves the guardians of history, and will simply act to destroy things they perceive as an unacceptable threat to the future. They were also designed for perfect confessional privacy.
- Renegade Splinter Faction: Turns out that the Silence the Eleventh Doctor was fighting throughout his entire life consisted of a mere splinter faction of the real, good (or at least Well-Intentioned Extremist) Silence.
- Shock and Awe: Their only way of killing someone in person.
- "The Wedding of River Song" reveals that they can only manipulate existing sources of electricity to create their lightning weapon, so they can be prevented from using it by being insulated from electricity sources.
- Shout-Out: According to Word of God, they were visually inspired by the famous painting The Scream.
- The Spook: The entire race is made up of Spooks because no one knows anything about them and it is hard to remember because you forget when encountering them.
- Squishy Wizard: As they rely on their psychic powers, their manipulations and sometimes lightning, they don't even bother to carry weapons. Fighting openly for them basically means lining up to be butchered.
- Staring Contest: Keep eye contact with them at all times, otherwise you forget them and they kill you.
- Super Not-Drowning Skills: They seem perfectly fine when immersed in liquid for long periods in "The Wedding of River Song".
- Well-Intentioned Extremist: They genuinely believe that the Doctor is too dangerous to be left running around. Their other goal is to prevent him from reaching the Fields of Trenzalore, where he will utter a secret that must never be spoken. It turns out they are trying to prevent another Time War occurring.
- Wham Line: "You should kill us all on sight." Not when they say it, but when it is used against them!
Gangers (Eleventh Doctor)
- "It's us or them."
- And I Must Scream: The partially melted down Gangers; rotting but fully alive and conscious.
- Body Horror: The rotting Gangers — partially melted but still conscious. There are eyes in one of the walls, made of more living Flesh.
- Chekhov's Gun: In "A Good Man Goes to War", a Ganger is used as a duplicate for Melody.
- Clones Are People, Too: Heavily explored and established, especially with the Gangers of Jennifer and Jimmy.
- Cloning Blues: After being cut off from the people they're based on they have a violent identity crisis because their memories say they are real but their circumstance says they're not.
- Continuity Nod: In "The Almost People", one decommisioned Ganger resembles the villainess Cassandra from "The End of the World" and "New Earth". The Gangers also seem to be "forced-growth clones", like Chip, Cassandra's servant.
- Deadly Euphemism: Gangers, being considered implements, are not killed but "decommissioned." Justified in that originally they were avatars of people, not sentient beings in and of themselves.
- Finishing Each Other's Sentences: This happens with the Doctor and his Ganger; same wavelength!
- Glamour Failure: The Gangers occasionally shift back to their gooey, half-formed selves for a brief moment.
- Go Mad from the Revelation: Ganger!Jennifer completely loses it thanks to all her memories of being 'decommissioned'.
- Hive Mind: The two Doctors manage to act as if they were still occupying the same skull. Which, in a way, they are. Both being essentially exactly the same person, it would make sense that they would know exactly what the other was thinking. The fact that Time Lords are telepathic couldn't have hurt, either.
- In-Series Nickname: The TARDIS team seem to have dubbed them "Flesh Avatars".
- Meaningful Name: "Ganger" comes from both "doppelgänger" (a duplicate of a person) and "ganger" (a menial labourer assigned to a large work gang, i.e. on old-fashioned railroads).
- Nightmare Face: An incomplete Ganger has a gooey white face.
- Replacement Goldfish: Two of the original humans are killed and their Gangers resume their lives for them.
- What Measure Is a Non-Human?: The Gangers are designed to be expendable — their purpose is to mine the acid, a horribly dangerous job, without putting humans at risk. Naturally, they aren't happy about this.
Tivolians (Eleventh and Twelfth Doctors)
Played by: David Walliams (Gibbis) (2011); Paul Kaye (Prentis) (2015)The Tivolians are a race of rodent-like humanoids from the planet Tivoli. Their homeworld was the most invaded planet in the galaxy, to the point where the Tivolians now actually enjoy being conquered and oppressed.
"If you occupied us, you'd be home by now."
- Les Collaborateurs: They willingingly comply with any conquerers. It's implied to be a species-wide survival strategy: if everyone knows they can be effortlessly conquered, no one ever tries to exterminate them.
- Dirty Coward: They straddle the line between these this and Lovable Coward. In "The God Complex", Gibbis' cowardice is often the source of humour, but his lack of bravery also gets someone killed and the Doctor is very unhappy with Gibbis after that.
- Getting Crap Past the Radar: In "Before the Flood", Prentis' love of being oppressed seems sexual in nature. The Doctor is not amused.
- Planet of Hats: An extreme example even for Doctor Who. An entire race of people who love being oppressed by invaders.
- Rubber-Forehead Aliens: Tivolians look like humans with rodent-like features.
- Stockholm Syndrome: One interpretation for why the Tivolians enjoy being oppressed.
- The Quisling: An entire planet who welcome any and all alien invaders. Their planetary anthem is "Glory to <Insert Name Here>".
Whisper Men (Eleventh Doctor)
Played by: Paul KaseyMysterious beings who work for the Great Intelligence. They appear to be extensions or manifestations of the Great Intelligence himself, as if he destroys his current form, he can then take the bodies of one of his Whisper Men.
"The trap is set. The Doctor's friends. Will travel where the Doctor ends."
- Badass in a Nice Suit: Dress in Victorian era garbs.
- The Blank: Lack facial features except for one large gaping mouth.
- Foil: To the Silence; while both wish to destroy the Doctor, they do so in completely opposite ways. The Silence wish for "Silence to fall" and their ultimate goal is to prevent the Doctor from saying his name. The Whisper Men want the Doctor to say his name aloud so the Great Intelligence can enter the Doctor's tomb. This also extends to their physical appearance, while both have Nightmare Faces and wear suits, there is one very important contrast. The Silence have large eyes and no mouth, the Whisper Men have a big gaping mouth and no eyes.
- Intangible Man: When Strax tries to strike them, his weapon passes right through. They can also phase their hands through their enemies' hearts.
- Mooks: To the Great Intelligence.
- Nightmare Face: Faceless horrors, save for one large snarling mouth.
- Rhymes on a Dime: Always speak in rhymes.
The Boneless (Twelfth Doctor)
"I tried to reach out, I tried to understand you, but I think that you understand us perfectly. And I think that you just don't care!"Creatures from another plane that only understand two dimensions, and have entered our world through Bristol and have started taking people and turning them flat.
— Twelfth Doctor
- Ambiguously Evil: It's really unclear why they decided to enter dimension, whether they want to communicate with us, study us or eliminate us one by one.
- Eldritch Abomination: Creatures that come from a 2-D plane of existence.
- Flat World: Their universe is two-dimensional, so they're from a very literal version of this trope.
- For the Evulz: As enigmatic as they are, it is made clear that they are gleefully aware of the harm they're causing.
- Hidden Agenda Villain: Their motives are left deliberately unclear and many hypotheses are brought up during the episode; perhaps they're here to contact us, kill us all, dissect or study us and don't even know that we require 3 dimensions to survive.
- Humanoid Abomination: Eventually they take the form of those they've killed when they finally understand 3 dimensions.
- Known Only by Their Nickname: Their real name is unknown due to being unable to communicate, the Doctor gave the name of "The Boneless" since he found "Killer Graffiti" rubbish.
- Paper People: Comes with being 2-D lifeforms.
- Starfish Aliens: Beings from a 2-D dimension that are attacking Earth.
- Starfish Language: The TARDIS is unable to translate their language because being aliens who don't understand the concept of a third dimension are even too bizarre for her standards.
- Stealth Pun: They're two-dimensional in more ways than one.
- They Would Cut You Up: Rare alien-on-human example. They turn humans into 2-D and dissect them to understand their bodies so they can become 3D.
- Zombie Gait: When they take the appearance of those they've killed, the creatures run after everyone this way. Having a rudimentary understanding of 3D and human anatomy, their walking style is crude and zombie-like.
Dream Crabs (Twelfth Doctor)
"The Dream Crab induces a dream state. Keeps you happy and relaxed in a perfectly realized dream world, as you dissolve."The Kantrofarri, colloquially known as the Dream Crabs, are telepathic parasites which feed on humanoid brain matter, and have the appearance of giant misshapen hands. They keep victims in a placid dream like state as they dissolve their brains.
— Twelfth Doctor
- Big Creepy-Crawlies: They're colloquially called "crabs", and have a spider-like movement, but actually resemble giant, misshapen hands.
- Dream Within a Dream: They create layer upon layer of dreams, so that the victim can never discern dream from reality.
- Enemy Within: Sort of. Once they've latched onto your face, your only means of survival is realizing it's a dream and breaking out from within your mind.
- Expy: Of the Facehuggers.
- No Body Left Behind: They crumble to dust once they die. The Doctor explains that this is a "carnivore's hazard, food has teeth too."
- Schrödinger's Butterfly: The Doctor states that there is no one who can ever be sure whether or not they are dreaming or not, and the Dream Crabs who create a Dream Within a Dream certainly make this much harder.
- Starfish Aliens: Creatures which look like misshapen hands, with no eyes, ears, nose, or mouth and rely on telepathy to detect the image within other nearby organisms.
- Sweeping Ashes: The first time they die and crumble to dust, Shawna comes in and sweeps them up.
- Telepathy: The only way they can sense the world around them. Literally homing in on the image of themselves in their prey's mind.
Cloister Wraiths (Twelfth Doctor)
Also referred to by the name "Sliders", Cloister Wraiths are dead Time Lords, whose minds have been forcefully uploaded into the Matrix. They're found beneath the crypts of The Citadel, and guard the Matrix from intruders; acting as a sort of firewall, ensnaring their prey with fibre optic cables and reducing them to raw data.
- And I Must Scream: Their faces are frozen in a perpetual rictus of horror.
- Cobweb of Disuse: What happens to their prey. The Doctor and Clara find Daleks, Cybermen and Weeping Angels that have been caught by them.
- Fate Worse Than Death: Becoming one of these things doesn't look very pleasant.
- Non-Human Undead: They're long dead-Time Lords, and appear almost akin to ghosts.
- Threshold Guardian: The Cloister Wraiths guard the Matrix. Anybody caught in there eventually becomes a part of the firewall.
- Virtual Ghost: They appear to be at least partially hologramatic, and they don't look happy about it.
Shoal of the Winter Harmony
Shoal of the Winter Harmony (Twelfth Doctor)
- Ascended Extra: They go from being relatively minor villains in The Husbands of River Song to the Big Bad of The Return of Doctor Mysterio.
- Bald of Evil: Scratch and the rest of the Shoal of the Winter Harmony members were like this, their successors in the The Return of Doctor Mysterio avert this.
- Big Bad: They serves as the main threat of the 2016 Christmas special.
- Brain in a Jar: They literally appear as brains in jars before they are transplanted to a new host.
- Brain Transplant: They infiltrate planets by transplanting their brains into that of civilians.
- Evil Plan
- Expy: They are not unlike the Slitheen as aliens who pretend to be humans by wearing the skins of their victims.
- Good Scars, Evil Scars: They can be spotted as having a telltale diagonal scar running across their faces, which can actually split open.
- Grand Theft Me: The modus operandi of this alien menace, who swap themselves into human hosts while removing their brains.
- Hyperspace Mallet: Harmony Shoal members are able to store things in their heads. Literally. They just split open their head and pull the item out.
- Kill and Replace: They surgically remove the brains of their victims, before one of their species is put inside the body as a vessel.
- Manipulative Bastard: Their Evil Plan is so brilliant that even the Doctor is impressed, before complaining how his side never comes up with ideas like this.
- Red Right Hand: Harmony Shoal Members can be distinguished by a telltale seam running diagonally down the side of their face, some of which may also have a tendency to exude blue liquid out of the openings in their faces.
The Pilot (Twelfth Doctor)
Played by: Stephanie Hyam (2017)A mysterious liquid entity formed out of spaceship oil that desires to consume a "Pilot" so that it may be controlled and return to the stars where it belongs. It was attracted by Heather's star-shaped defect and desire to "escape" and fused with her. From there it pursued Heather's crush, Bill Potts, across space and time, driven by her promise not to leave without her.It was unknown how much of Heather's humanity survived the fusion with the sentient oil. As it turns out, all of it did. Including her love for Bill.
"I'm The Pilot. I can fly anything. Even you."
- Chekhov's Gunman: While she was a Monster of the Week, Pilot!Heather returns just in time save Bill from total Cyberman conversion and gives her the power become a Pilot in the season 10 finale.
- Offscreen Teleportation: After consuming Heather it gains the ability to form itself out of humid surfaces such as puddles or the steam in mirrors, allowing it to follow the TARDIS around.
- The Power of Love: Bill and Heather's love was strong. So strong that the Pilot kept something of hers, her own life water, as a way to hold onto Bill so that she could return to her one day.
- Reality Warper:
- Alongside it's teleportation abilities, the Pilot is capable of time-travel, shape-shifting, instant regeneration and mimicry.
- As of its return in The Doctor Falls, Pilot!Heather seems to have mastered atomic reconstruction, making it a literal example of this trope.
- Stalker With a Crush: After consuming Heather, the Pilot creature begins pursuing the TARDIS to transform Bill Potts into a "Passenger", these impulses are caused by Heather's feelings for Bill.
- Swiss Army Tears:
- The tears planted on Bill by Pilot!Heather are used to locate and rescue her after her conversion in the Mondasian Ship.
- After leaving the Doctor's corpse in the TARDIS, Passenger!Bill leaves a tear on his forehead, allowing his regeneration to begin.
Emojibots (Twelfth Doctor)
A group of robots who are put in charge of one of the first interplanetary human colonies, their primary functions are to mantain structural integrity, pollinize and water crops, and ensure that no inhabitant of the colony is ever dissatisfied.
- The Worm That Walks: The Emojibots' bodies and conciousness turn out to be part of a sentient hivemind formed by nanomachines called the "Vardies".
The Dryads (Twelfth Doctor)
A species of small, possibly alien insects capable of merging and transforming people into wood, a group of them inhabit the Landlord's house, obeying his commands through high-pitched sounds.
- Big Creepy-Crawlies: Each dryad seems to be about the size of a fist.
- Insect Queen: The Landlord seems to be the one ordering the Dryads and giving them sustenance. Averted when it turns out Eliza, the Landlord's mother is the one with an actual psychyc connection to the lice, hinting at a possible Hive Mind.
- Plant Person: The Landlord's mother, Eliza, was transformed into living wood by the Dryads many years before the events of the story, recieving sustenance from the people fed to the dryads by the Landlord.
Smartsuits (Twelfth Doctor)
High-tech spacesuits built by Ganymede Systems and given to the staff on the Chasm Forge space station. They provide oxygen to the wearers (provided they can pay for it), but in certain situations they will "deactivate" their organic components (i.e. wearers) and attempt to do the same to anyone else.
- A.I. Is a Crapshoot: This is the Doctor's initial assumption. Subverted. They're doing exactly as they've been ordered by the Ganymede Systems executives, who want the "inefficient" workers dead and not using up valuable oxygen.
- Animated Armor: The suits can move on their own, even with nobody inside.
- Exact Time to Failure: When still being worn by living people, the suits list the average number of breaths of oxygen that they have left. (Not the time they have left, because you breathe faster under stress, say if you're being pursued by your dead colleagues in those same suits...)
- Have a Nice Death: "Please remain calm while your central nervous system is disabled. Your life is in our hands."
- Our Zombies Are Different: Walking corpses with a Zombie Gait that create more of themselves from those they kill? Yes, but these corpses are just being puppeteered by the suits they're wearing.
- You Have Outlived Your Usefulness: The suits are programmed to exterminate their wearers because Chasm Forge's mining operation has become unprofitable. The suits can keep doing the work while the useless humans stop wasting oxygen that the company can resell.

- Arc Villain: For a sequence of episodes starting with "Extremis" and ending with "The Lie of the Land".
- Bond Villain Stupidity: They fall into this big time in "The Lie of the Land". They do very little to actually stop the Doctor and his companions foiling them.
- The Chessmaster: They run simulations of a race's entire history to find the perfect moment to manipulate that race into asking to be conquered.
- Internal Retcon: They maintain their rule with a signal that makes everyone believe they've always been in charge.
- Laser-Guided Amnesia: They remove all trace of themselves from Earth after they are defeated.
