Mutants. Cyborgs. Aliens. Complete and utter bastards and the favorites of many small children. A species of genetically engineered xenophobes native to the planet Skaro, whose general purpose for existence is to "EXTERMINATE!" all non-Dalek forms of life in the universe. Created by a Mad Scientist
named Davros. The Daleks' physical form is shriveled and weak, but make up for that by having each individual travel in a distinctive set of mobile armor. The
first villainous alien race introduced in the franchise (in the second serial
, in fact), and the most endearingly popular.
- Absolute Xenophobe: "There is only one kind of life that matters. Dalek life."
- They're so xenophobic that even a small amount of non-Dalek material in their flesh drives them mad and/or suicidal. As cloning and/or genetic manipulation seems to be their primary means of reproduction, even being created from altered non-Dalek or non-Kaled cells is unacceptable for them. "Impure" Daleks will eagerly line up for disintegration to preserve the species' purity.
- Always a Bigger Fish: The Doctor, who they refer to as "The Predator of the Daleks".
: Imagine you were dying. Imagine you were afraid and a long way from home and in terrible pain. Just when you thought it couldn't get any worse, you looked up and saw the face of the Devil himself... Hello Dalek! Dalek
: Emergency! Emergency! Weapon System Disabled! Emergency Protocols Have Been Breached! Emergency, Emergency, Emergency!
- Rose could also count considering what she did to the Dalek Emperor and an entire army with just a wave of the hand.
: If you um...escaped the Time War don't you wanna know what happened. What happened to the Emperor? Dalek
: (Beat) The Emperor survived?! Rose
: Till he met me
. Cause if these are gonna be my last words than you're gonna listen. I met the Emperor and I took the Time Vortex and I pulled it into his head and turned him into dust. Did you get that? The God of all Daleks and I destroyed him!
- River Song could also qualify. She had that one Dalek begging for mercy as soon as it learned her name.
- Always Chaotic Evil: Averted with Dalek Sec, Oswin Oswald, Rusty, and to a lesser extent Dalek Caan. But they are generally the exception that proves the rule, and did not change on their own. The overwhelming majority are genocidal death machines.
- Arch-Enemy: The species as a whole is this for the Doctor.
- Attack Its Weak Point: The eyestalk. Hitting it with enough power will kill the Dalek, and blinding it will cause the creature to panic. Became much less of a Weaksauce Weakness in the revival; their force field protects it (the Doctor claims concentrating fire on it could work, but this appears to have mixed results), and trying to blind it with paint only worked for a second. River managed to kill one with a blast to the eyestalk, but this particular Dalek was already in such poor shape that it needed several minutes to recharge between shots.
- Big Bad: Archenemies of the Doctor and everything else. Quite fond of the Evil Plan in the revival, to the point where, during Russell T. Davies' era, it was a surprise not to find them the masterminds behind the season's Apocalypse How. Main Antagonists of the 2005 and 2008 series.
- Big Bad Ensemble: Of the 2006 series, with the Cybus Cybermen.
- Bigger Bad: They serve as the Doctor's final opponents in both 2013 special episodes, The Day of the Doctor and The Time of the Doctor.
- Bond Villain Stupidity: All enemies of the Doctor suffer this to some extent, but the Daleks compound it with Wrong Genre Savvy.
- Breakout Villain: They very nearly never appeared at all, but are now at least as iconic as the TARDIS.
- Canon Discontinuity: Several bits of the Daleks' stories are continually discarded for one reason or another. This ranges from the time the producers tried to make them comic relief to that time the guy who made them forgot that they weren't robots.
- Can't Use Stairs: A Running Gag.
- Subverted, however, in "Remembrance of the Daleks." The first episode cliffhanger was the Doctor fleeing up the stairs and thinking he was safe from the Dalek chasing him, only for it to start levitating up the stairs after him.
- Happens again in "Dalek", where Rose tells folks the pursuing Dalek won't be able to follow them up the stairs. The Dalek announces "EL-E-VATE!" and begins levitating up them. This was put in after one of the writers asked his girlfriend why she thought the Daleks made rather pathetic villains in the original show, and she told him how easy they were to foil.
- Catch Phrase: "EX-TER-MI-NATE!"
- There's also "EX-PLAIN! EX-PLAIN!", "I OBEY!", and "MY VISION IS IMPAIRED! I CANNOT SEE!"
- The Supreme Daleks quite often yell "EXPLAIN!"
- Ever since "The Day of the Doctor", the phrase "Seek, Locate, Destroy." seems to have become their mission statement.
- Characterisation Marches On: The original Daleks were vastly different from what they would become. They hated the Thals completely, but were willing to keep the Doctor and his companions alive, even feed them. They required radiation and a constant supply of electricity to survive. And they didn't even say "EXTERMINATE" more than once or twice.
- Although it is to be noted that the first story takes place in the Dalek's past, before they had archeived space flight; It might simply have been a case of both their Technology and society marching on in-universe.
- Cold-Blooded Torture: In the novel Prisoner of the Daleks, it is revealed that the Daleks adjust their death ray to the level required to kill their target... and then dial it down a notch, so the victim suffers a moment of excruciating agony before they die.
- Color-Coded for Your Convenience:
- More than one serial in the old series had a Black Dalek in a position of authority over the others.
- In the 1980s, the Daleks split into two factions: the Imperial Daleks had cream casings with gold highlights, while the Rebel Daleks were a more traditional grey and black.
- In the new series, the New Paradigm Daleks have a rainbow of casing colours. Supposedly it denotes their functions, but it's never come up at all in an actual episode.
- Conservation of Ninjutsu: One Dalek? You're so screwed. A full Dalek Empire? They're so screwed.
- Though it should be pointed out, they do cause quite a bit of collateral damage before they go down. Just not to the main cast of the episodes.
- Contractual Immortality: A literal Real Life example. The deal with Terry Nation's estate contractually obligates the producers to bring them back at least once per season.
- Creepy Monotone: Averted. It sounds more like they're trying to choke back their disgust with all other life.
Tenth Doctor: Technology using the one thing a Dalek can't do. Touch. Sealed inside your casing. Not feeling anything ever, from birth to death, locked inside a cold metal cage. Completely alone. That explains your voice. No wonder you scream.
- Cruel and Unusual Death: That Death Ray they use? It doesn't just kill you. You die in agony.
- Cyber Cyclops: The production team has added pupils to the 2010 models, making the eye-stalk look almost organic.
- Deflector Shields: The revival gave them personal force-fields that can melt bullets before they even hit home. Even guns capable of destroying the bullet proof Cybus Cybermen have no effect on them.
- Determinator: They never give up. You have to admire a species that manages to survive even after being made extinct. Repeatedly. And for never turning a blind eye to their mortal enemy, the Doctor, who has been responsible for several of those mass extinctions. An enemy who became a warrior to fight them personally when they declared war on his people- a race so advanced they could dismantle reality if they wanted to. And ended that very same war by turning their numbers against them. What did the Daleks do? Enter a second war with the Doctor alongside his worst foes when he was on the verge of rescuing his own people. And even then continued to do battle for centuries after everyone else gave up and they had tried to kill him so much he finally began to die of old age.
- During the Time War, the Time Lords threw literally everything they could think of at the Daleks: super-weapons, Eldritch Abominations, altering time itself, and not a single one of these attempts slowed the Daleks down at all.
- The Dreaded: In a universe full of any number of beasties, psychopaths and gods, the Daleks are consistently shown to be the #1 fear of those who've fought them, the Doctor included.
- In turn, the Doctor is this to the Daleks. There is a reason they call him the Oncoming Storm.
- Elite Mook: The Special Weapons Dalek.
- Enemy Civil War: Twice on TV: first in "The Evil of the Daleks" when the Doctor infected a group of Daleks with the Human Factor and second in "Resurrection of the Daleks", "Revelation of the Daleks" and "Remembrance of the Daleks" in which Davros creates upgraded Imperial Daleks, conditioned to be personally loyal to him as their emperor. It led to a war with the baseline Daleks.
- Everything's Better with Spinning: Averted with Daleks, who have a tendency to spin around in circles before they blow up.
- Evil Is Hammy: DAAALEKS ARE-SUPERIOR-HAMS-TO-THEM-AAALL!
- Evil Sounds Deep: Not the rank and file, with their famously shrill and screechy tones, but high ranking Daleks sometimes have low, booming voices. Case in point, the 2005 Emperor and 2008 Supreme.
- The Farmer and the Viper: When facing their own defeat or perhaps simply wishing to gain an advantage, the Daleks often count on their foes being a Good Samaritan and always cry "Have pity!" or beg for help in order to bite back and destroy their enemies when they have the chance. Averted when one tries it on River Song.
- Feeling Oppressed by Their Existence: They feel this way about every single non-Dalek in the universe, and occasionally by Daleks of "inferior" designs also.
- Flying Saucer: The standard make of their starships going back quite some time.
- Gold-Colored Superiority: The rank structure of the Daleks places Golden Daleks high in the heirarchy.
- Human Resources: They're not above converting other life-forms into Daleks if they need the numbers (Parting of the Ways) or the subject is too useful to pass up (Asylum). Or if Davros feels like making a point - he had this done to eight billion humans in the audio Terra Firma, just to twist a knife in the Doctor.
- I'm a Humanitarian: "Into the Dalek" reveals that Daleks feed on a protein goop processed from the carcasses of their victims.
- Immune to Bullets: They're (mostly) vaporized by a forcefield before they can make contact. And even without their shields, bullets in the revived show never have any effect on them.
- Imperial Stormtrooper Marksmanship Academy: Inverted in the revived series. Unique among Doctor Who villains, the Daleks NEVER miss, even when shooting at the Doctor himself. Ascended into Improbable Aiming Skills in Victory of the Daleks where we see one shoot down airplanes.
- In Love with Your Carnage: They built the Dalek Asylum to contain Daleks that were too violent and insane even for them to control and refuse to destroy them because they find such pure hatred to be beautiful. It has an entire wing containing the Daleks that have gone insane in battles with the Doctor, which are judged to be so dangerous and unstable they must be kept separate for the protection of the other prisoners.
- It's suggested that this might be the reason why they've never been able to finish off the Doctor.
- Joker Immunity: Too iconic to ever kill off.
- They've been completely wiped out to the last in their first appearance, and several times ever since. At this point, being completely destroyed only to return later is as much part of their character as their voices or their casings.
- The Daleks have even acknowledged this in-universe: when the Doctor has said they're on the path to destruction if they don't change their ways, the Daleks point out that their species always survives.
- Even their own planet, Skaro, has come back after being explicitly destroyed. For bonus points, the Seventh Doctor destroyed it with the Hand of Omega, but much later went there to pick up the Master's ashes in the movie. (He has a time machine.)
- King Mook: The Dalek Emperor is usually a Dalek mutant in gigantic casing.
- Lack of Empathy: It's kind of a requirement when your ambition is to wipe out everything that isn't you. They understand "pity" and "mercy" only as something to demand from enemies when they're vulnerable, and the idea of empathizing with other life-forms is one of the few things that scares them besides the Doctor.
- Large Ham: Especially when voiced by Nicholas Briggs.
- Laser-Guided Amnesia: Inflicted on all of them in "Asylum of the Daleks". It did not last long. Undone when they "harvested" the memories Tasha Lem had of the Doctor after converting her into a Dalek puppet in "Time of the Doctor". Whether this restored their memories or replaced them isn't entirely clear though.
- "Into the Dalek" reveals that the Dalekanium transport shell does this to all the Daleks on purpose, suppressing any memories that might lead the Daleks away from the "purity" that Davros had envisioned for them all way back in "Genesis of the Daleks".
- Leitmotif: The appropriately titled "The Daleks".
- Low Culture, High Tech: Much like their real life inspiration, and a great part of what makes them so scary. They are one of the most advanced races in the 'verse, even making regular use of Time Travel, but all they ever conceive of doing with their spaceships is find new places to raze.
- Mass "Oh, Crap!": Not infrequent with them. After all, the Doctor is the only thing in the universe that can inspire in them anything other than hatred or contempt. They're afraid of him.
- Master Race: As one Dalek says in Victory of the Daleks, the fundamental basis and belief of their entire culture.
- Mind Rape: "Into the Dalek" reveals that Dalek tech does this to them on purpose, to reinforce the notion of their Omnicidal Maniac status. Any memory that might lead to a moral or existential epiphany is forcibly suppressed.
- Morality Dial: As revealed in "Into The Dalek", each Dalek's internal CPU constantly purges any information that could induce even the slightest amount of compassion or empathy.
- A Nazi by Any Other Name: The Kaleds, ancestors of the Daleks, wear black military uniforms very close to the standard Nazi uniform, complete with faux-Iron Crosses at the neck, and give Roman salutes with heel clicking. They're very fond of shouting a lot, violent threats and talk about racial purity. They get painted as Nazis IN SPACE. This is not surprising, since the Daleks themselves were one of the few Nazi-esque villains who were explicitly meant to be substantively Nazi-like, as opposed to just generic Nazi symbolism to make sure the dimwitted know when to boo. It was nicely lampshaded in the 2008 episode "Journey's End" where Martha teleports to Germany to play her part in activating the Osterhagen Key, and Daleks can be heard shouting in German "Exterminieren!" Possibly even more so in "The Dalek Invasion of Earth" (1965) where the Daleks refer to the destruction of the human race as "the Final Solution" and greet each other by jerking their plungers upwards.
- Bonus for the Thals stating that the Kaleds used to be thinkers and scientists before the whole skarosian mutual extermination war got started and the fanatists took over the place; It is to be noted, however, that "Genesis of the Daleks" itself adds a bit of Cold War subtext as well.
- Nice Job Fixing It, Villain: Part of the reason the Doctor wouldn't destroy the Daleks while they were being developed in "Genesis of the Daleks", for all the times they've done this.
The Doctor: I know that although the Daleks will create havoc and destruction for millions of years, I know also that from their evil must come something good.
- In "Into The Dalek", the Doctor admits that it was his first encounter with Daleks that changed his less-altruistic first incarnation into the force for good he would later be known for.
- Nigh-Invulnerability: They started out as tanks, and since the revival they have forcefields that make them immune to nearly everything except their own weapons, only because there aren't any defenses against them. Earlier stories had their eyestalks, but that's a very small target (and the force field covers that now, too).
- Energy Weapons of sufficient power seem to do the job; the modified defabricator blows them clean open, and the lightning guns from parallel Earth / Pete's World were at least able to disable them for a while once the Doctor modified them. Other Pete's World weapons seemed specifically designed to kill them.
- Ninja Zombie Pirate Robot: Mutant Alien Cyborg Nazi.
- No Indoor Voice: Even in normal conversation (or what passes as such for a Dalek), their voices are loud, harsh, and screeching.
- Omnicidal Maniacs: The only fitting fate for all non-Dalek life is death.
- Once a Season: The BBC's deal with the Nation estate means they have to appear in some form at least once a year, even if they have to shoehorn in a cameo, as in "The Waters of Mars" and "The Wedding of River Song". In Classic Who, after 1965 the Daleks turned up less frequently, but this still somewhat applies as every Doctor faced them at least once.
- One Alien Army: In the revived series, if only a few individual Daleks appear, they're usually almost unbeatable and killing even one of them becomes a huge task. Special mention to the Special Weapons Dalek, which was able to win the battle in "Remembrance of the Daleks" single handedly, and it was against other Daleks.
- The Paranoiac: An entire species of paranoid xenocidal maniacs. Genetically programmed to feel hatred for all forms of non-Dalek life, they live in pressured pepperpot tanks both for mobility and because they are utterly terrified of being somehow infected by interacting with other lifeforms. They have a highly rigid command structure and are perfectly willing to die for the cause of racial purity, with their ultimate aim being the eradication of all life everywhere so that the Dalek race will be protected from contamination from their supposed biological inferiors.
- Roar Before Beating: "EX-TER-MI-NATE!"
- Scary Dogmatic Aliens: They're Nazis In Space!, with the odd religious fundamentalist overtone, such as in "The Parting of the Ways".
- Significant Anagram: The Daleks were originally engineered from a race called the Kaleds.
- Spikes of Villainy: Not on their cases, but on their DNA.
- Starfish Aliens: What the Daleks are within their metal casings.
- Starfish Robots: What the metal casings themselves are.
- The Starscream: They have repeatedly turned against and overthrown their creator, Davros, only to come crawling back when they are weak, because he is smarter than them. Not smart enough to have realized that when he created a race that thinks they are superior to everyone, that would include himself, though. Subverted Trope in the 2005 revival episode "The Stolen Earth"; the Daleks don't even pretend to respect him this time, and are keeping him as a "pet".
- Strong as They Need to Be: Their Death Ray weapon, justified depending on how much power is used in it. It varies from being enough to kill a human or a Cybus Cyberman, to blasting a hole in a bomb shelter blast door.
- Super Soldier: They have one, the Special Weapon Dalek, which has a different casing from its fellows, and is far stronger, capable of incinerating three Daleks in one shot. Apparently it's crazier than the average Dalek, due to the radiation its weapon produces. Daleks being Daleks, they think it's an abomination and have to be told not to kill it.
- Talking Lightbulb: Their "ear-lamps" flash in time with their speech.
- Technology Marches On: In-universe. One of the few species besides humanity that is depicted in different stages of their developement - When we first saw them, before they reached space flight, they were dependent on external power sources. They had remedied this with disk-like acessories in the 22th century, and engineered their casings to not even need these further ahead. They also archeived time travel at some point and multiple wars and conflicts in their history/ the future are known. At some point, they also experimented with making themselves completely mechanical. Later in the classic series, and most of the new one, we mostly encounter those far future Daleks occassonally ending up back on present!Earth.
- Too Dumb to Live: They have an unfortunate habit of becoming this, particularly when their "vision is impaired!!!" Naturally, as they are unable to see, they will begin shooting wildly, in one case causing the Dalek to destroy itself when in a hall of mirrors in "The Five Doctors", and making for very annoying gameplay in the 2010 Adventure Game, City of the Daleks. Apparently their vision isn't the only thing that is impaired when they are damaged.... Lampshaded in "The Stolen Earth". A Dalek's "eye" is blinded, but the Dalek remedies it and says "My vision is not impaired."
- Took A Level In Bad Ass: They've taken several throughout the years. First, being able to leave the confines of their city, then conquering Earth, then developing time-travel. It got to the point the Time Lords started to get concerned about them, sending the Doctor to try and interfere with their origins. When they returned in 2005, they take another huge leap forward, when it's revealed they started a war with the Time Lords, and not only managed to hold their own, but very nearly won. And that's before we see them on-screen. The Ninth Doctor is utterly terrified to be locked in a room with a Dalek, and with good reason. Oh, and now, they can fly.
- Their increase in threat level is most apparent when you see how the characters aprove them: Back in the classic series, two strong men (or just one Ace) with a blunt object could usually ambush and incapacitate one; In the new series, you need at least a futuristic raygun to even stand a chance, and in large numbers, only a major plot event/deus ex machina can stop them.
- Tortured Monster: A deformed, irradiated mutant locked inside an unfeeling metal cage from birth to death...and programmed to be utterly revolted by everything outside that cage. The prospect of deviating from Dalek purity even slightly is enough to turn them suicidal.
- Turned Against Their Masters: They do this very often, mainly because Davros has no sense of pattern recognition.
- Unwilling Roboticisation: The Robo-Men (not to be confused with the Cybermen). The Daleks' low-level police/enforcers during their 22th century invasion of Earth.
- The new series reveals that the Daleks still use robotized humanoid servants around the 51th century, in form of their Dalek Puppets. These are significantly insidious in that they can function as Manchurian Agents, acting like they did while alive, until an eyestalk unexpectedly bursts from their forehead...
- Villain Decay: Thought to have happened after Davros appeared, where the Daleks were reduced to Mooks. They seemed to re-establish themselves slightly at the end of "Revelation of the Daleks" and finally in "Remembrance of the Daleks" a faction are fighting Davros.
- Largely undone in the revival series. The titular Dalek in "Dalek" wiped out the whole of the underground base on its own. "Asylum of the Daleks" shows that they can convert human beings into unwitting meat puppets, or even full on Dalek conversions. And "Into the Dalek" shows the inner workings of the outer shell, and the horror of just what Daleks do to themselves on a daily basis just to maintain their "purity".
- Weaksauce Weakness: Stairs used to be this for them. Used to.
- Worthy Opponent: The Doctor. They hate him with a passion that burns with all the hate they can muster, but they also respect him so much that their equipment will accept his word that an individual is a Dalek, even if their DNA is too degraded to register as a proper one.
- "Asylum of the Daleks" suggests that their respect for the degree of hatred he feels for them inhibits them from killing him, although the Dalek in question may just have been messing with the Doctor's head.
- Wrong Genre Savvy: The Daleks are well aware the Doctor always has something up his sleeve, and they also know he's good at not getting killed, so being able to kill him effortlessly, they reason, is never going to happen, so they let the Doctor talk/screw around with the Sonic Screwdriver in the hopes they can anticipate whatever backup plans he had to screw them over, then they figure he can be killed. Often enough, there was never a plan to begin with.
- X-Ray Sparks: The special effect used for their Death Ray since 1988.
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/Daleks. The war between the two races lasted a thousand years.
- 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.
- 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.
- 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.
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.
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.
- Blondes Are Evil
- 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.
Cybermen (First, Second, Fourth, Fifth, Sixth, Seventh, Eleventh and Twelfth Doctors)
You belong to us. You shall be like us.

(2010-present); David de Keyser (2012)
The Mondas/Telos Cybermen come from the tenth planet of the Earth's solar system ("Earth's long-lost twin planet"). note
Originally a fully organic humanoid species, they started replacing more and more of their biology with robotics to extend their life, to the point that have next to nothing living inside them, including emotions. Have been around for a while, first appearing in "The Tenth Planet
" in 1966. Shown little consistency in appearance, other than usually having "handlebars" on the sides of their heads.
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
- 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, and Eleventh 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)
Voiced by: Nicholas Briggs
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 have been made to bring them back from time to time — but the final attempt was scheduled to be in the 1990 season of Doctor Who
... and with the series 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"
- 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.
- Heel-Face 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. Also a Martian ship appears at the episode's end.
- 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.
- 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.
- Put on a Bus: They basically vanished completely after 1974, but returned for Eleventh Doctor story "Cold War".
- Red Eyes, Take Warning
- The Reptilians
- 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
- 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: Just look at them!
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
Time Lords (Second, Third, Fourth, Fifth, Sixth, War, Tenth, and Eleventh 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.
- 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 one giant city encased in a massive glass dome.
- 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.
- Abusing the Kardashev Scale for Fun and Profit: They made the whole of time and space their plaything. It's safe to say, many races pray to deities that are less powerful than the Time Lords.
- 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.
- 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.
- 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.)
- 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.
- 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.
- Can't Argue with Elves: Appears to be a species trait.
- Character Death: In the revival series, they are all dead as a result of the Time War, an offscreen event that was caused by the War Doctor and led to the extinction of their race. However, in "The Day of the Doctor", one of the biggest Wham Episodes in Doctor Who history, they are saved by the efforts of all thirteen Doctors working together and sealed away into an alternate universe. As the painting's name indicates, Gallifrey Falls No More.
- Corrupt Bureaucrat
- Crystal Spires and Togas
- Dying Race: Due to the Last Great Time War, the Time Lord race was rendered functionally extinct. Only the Doctor and Jenny are currently still alive, River is dead (sort of) and the Master's current status is still unknown. As for the Doctor's own family, he claims they are now deceased, but we still don't know precisely what happened to Susan after she was dropped off on Earth by the First Doctornote
- In "The Day of the Doctor", the timeline is altered by the combined efforts of thirteen incarnations of the Doctor. This lead to the entire population of Gallifrey being saved and shunted into a pocket universe. Gallifrey Falls No More!
- 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.
- It's later shown that this extends to the Time Lord Council, especially under the leadership of the revivied Rassilon. The soldiers actually fighting the war and the civilians caught in the crossfire are a lot more sane.
- Gender Bender: Missy, the Master's latest incarnation, 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 Shada (a Fourth Doctor novel, published in 2012) 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) sees to imply that they are all gender fluid.
- Good Is Not Nice: They are the most powerful and mighty race in the universe, self-appointed guardians of all time and space. 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: Only when the regeneration has started. Before the Time Lord changes completely, the body heals all the injuries and may rejuvenates the individual.
- Higher-Tech Species: Scratch that. They were the higher tech species.
- Human Aliens:
- 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.
- Impossibly Tacky Clothes
- 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.
- Mystical High Collar: Their formal robes have massive 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 "The Forest of the Night", he calls Earth "his world", perhaps exactly because this trope is no longer in play - Now that he knows he didn't blow up Gallifrey after all, he no longer has to feel guilty about feeling more at home with the "pudding brains".
- Nice Hat / High Collar of Doom: 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.
- Omnicidal Maniac: Their plan in "The End of Time" involves the destruction of time itself.
- The Omniscient Council of Vagueness / Not-So-Omniscient Council of Bickering: They tended to be one or the other, 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 (which they were responsible for) to grant the Doctor a new cycle of regenerations, allowing him to regenerate into his fourteenth incarnation. 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.
- Screw The Rules, We Make Them: The Time Lords aren't shy about letting other races know this.
- 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.
- 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: Renegade Time Lords and Ladies who leave or are exiled from Gallifrey forfeit their names and take up "titles" instead and 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.
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
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
- Manchurian Agent: Some later model Autons come with fake memories.
- May Contain Evil
- 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.
: 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
Homo reptilia note (Third, Fifth and Eleventh Doctors)
We are the last of our people.
Silurians voiced by: Peter Halliday (1970)
Silurians played by: Norman Comer, Stuart Blake and Vincent Brimble (1984), Neve McIntoshnote (2010-present) and Richard Hope (2010-12) note , Stephen Moore (2010)
Sea Devils played by: Pat Gorman and Peter Forbes-Robinson (1971), Christopher Farries (1984)
A bunch of 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 an unknown deep-sea creature.)
- 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.
- Kill 'em All: Has a distressing tendency to happen to them whenever they appear, despite the Doctor's best efforts.
- 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.
- 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.
- 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
- Taxonomic Term Confusion: Homo Reptilia? Considering the Homo genus is mammalian.
- Proud Warrior Race:
- The Warrior Caste Silurian.
- 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.
- 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.
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.
- Hive Mind: The seemingly individual Axons are all part of the same entity.
- 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.
- 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.
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
- Ambiguously Human: They can breed with humans and produce fertile offspring with no biotechnological intervention, which in a more realistic series would strongly suggest that they're actually a lost human colony. Although in Doctor Who, humans can breed with cats.
- 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.
- 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
- Wutai: Draconia is basically feudal Japan in space with reptile people.
Sontarans (Third, Fourth, Sixth, Tenth and Eleventh Doctors)
Sontar HA! Sontar HA! Sontar HA!
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)note
A 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 somehow tied to their never ending war against the Rutans (a race of... intergalactic jellyfish).
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
- 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 and Eleventh Doctors)
Played by: John Woodnutt (1975), Ian Marter (1975), Lillias Walker (1975), Jemma Redgrave (2013), Ingrid Oliver (2013), Jonjo O'Neill (2013), Joanna Page (2013), Nicolas Briggs (voice, 2013)
The Zygons are a race of metamorphic humanoids. After their planet was destroyed in a stellar explosion, they seek to colonise other planets, including Earth.
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.
Movellans (Fourth Doctor)
We are infinitely superior.
The Movellans were androids who warred with the Dalek Empire.
- 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 being being to 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.
- Plaguemaster: The Movellan Virus was developed by the Movellans to attack Dalek casings and tissue.
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 (As 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 Unexpected Guest, the Seventh Doctor might have found a loophole.
- For the Evulz: As shown in the Doctor Who Magazine story Unexpected 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 there accessing helps greatly).
Revival Series Debut
The Slitheen family note (Ninth Doctor)
Victory should be naked!
—Jocrassa Fel-Fotch Passameer-Day Slitheen
Playednote and voiced by: Annette Badland, David Verrey, Rupert Vansittart, Eric Potts and Steve Spiers (2005)
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.
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.
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.
- The Cameo: In "The End of Time", "The Pandorica Opens" and "The God Complex".
- 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.
- Planet Spaceship: The Sycorax come from an asteroid named Fire Trap, which was retrofitted into a starship when one fell upon it's surface. They eventually built an entire Armarda out of captured and colonised asteroids.
- Proud Warrior Race Guys
Clockwork Droids (Tenth and Twelfth Doctors)
We did not have the parts.
The Clockwork Droids are servile droids used in the 51st Century, notably on ships like the SS Marie Antoinette
and the SS Madame de Pompadour
. They have an unfortunate tendency, when the ships have no available spare parts, to use living beings, including humans, as suitable replacement 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.
- 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
- Costume Porn: The SS Madame de Pompadour droids are possibly the best dressed Doctor Who villains ever.
- Creepy Monotone
- 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
- Ragnarok-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".
Cybus Cybermen (Tenth)note Doctor)
The parallel Earth Cybermen (or Cybus Cybermen or Cybusmen, after the evil corporation that created them). These Cybermen come from a parallel universe. Have been around for a while, first appearing in "Rise of the Cybermen"
in 2006. Get sent into the Void between dimensions, from where they neatly spill over into the regular timeline.
Ood (Tenth and Eleventh Doctors)
The circle must be broken, so that we can sing.
Voiced by: Silas Carson (2006-10,2012)
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.
Judoon (Tenth and Eleventh Doctors)
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.
- 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.
- Perpetual Frowner
- Rhino Rampage
- Space Police
- Trigger Happy: especially in The Sarah Jane Adventures.
Weeping Angels (Tenth and Eleventh 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!
— Tenth Doctor
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. If need be, they'll transport their victims back through time and then feed on their lives spent in the past. If they're not feeling quite so creative, they'll just snap their victim's neck like a twig. One of the creepiest aliens in the history of the series.
- 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...and 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.
- 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.
- Bizarre Alien Biology: Creatures of the abstract. They turn to stone when anyone is looking. Ultimate defence 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 recent poll, and get a lot of appearances outside their own story arc.
- Creepy Changing Statue
- 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.
- 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
- 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
- Fate Worse Than Death: Not in their first appearance, where they "kill you nicely" and get enthusiastic testimonials from their victims. But played dead straight in their second, where while they kill most of their victims, they partially reanimate Sacred Bob into a mouthpiece for the Angels. And in their third, where 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.
- The Fourth Wall Will Not Protect You: In "The Time of Angels", where "an image of an Angel becomes itself an Angel".
- 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.
- Hoist by His Own Petard:
- 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
- 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
- Light Is Not Good: They look like statues of angels...at first. 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
- 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.
- 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 bullet 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.
- Neck Snap: Normally, the Weeping Angels are killers... but should they not need to feed on a person's temporal energy... crack goes their neck. And 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 one 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. 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.
- Nightmare Fuel Station Attendant
- Nobody Here but Us Statues
- Offscreen Teleportation: Their explicit super-power.
- Only Known by Their Nickname: The actual name of the species, if there is one, is unknown.
- Our Gargoyles Rock
- 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.
- 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.
- 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.
- Or bronze. Or copper. Or whatever else statues are made of. 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.
- 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. Averted later in "Flesh and Stone", but un-averted in "Angels Take Manhattan".
- 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.
- Time Abyss: They're as old as the Universe. Or very nearly.
- Writers Cannot Do Math: The Statue of Liberty should be more than twice the size shown.
Adipose (Tenth Doctor)
A friendly race of marshmallow-like blob creatures that appeared primarily in "Partners In Crime", created from living fat.
Vashta Nerada (Tenth Doctor)
These are our forests. They are our meat.
Also known as "The Shadows that Melt the Flesh
", the Vashta Nerada are tiny scavengers that hide in the shadows, any shadows, before consuming their prey. They are found on every world, including Earth.
- The Croc Is Ticking: You can tell that a swarm of Vashta Nerada has eaten someone when the microphone in their spacesuit breaks and keeps repeating the same thing over and over again.
- Darkness Equals Death: If you enter a shadow that the Vashta Nerada occupies, you will be devoured.
- Living Shadow: Trope Namer. 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/The Worm That Walks: 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 Silent Priests
The Silence (Eleventh Doctor)
Silence will fall.
Played by: Marnix Van Den Broeke (2011)
Voiced by: Barnaby Edwards (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.
Gangers (Eleventh Doctor)
It's us or them.
The Gangers were a clone race created by humans from an artificially created organic substance called the Flesh.
Gangers were primarily created so workers who had extremely dangerous jobs could work without body harm or death. The Ganger is just an avatar, a robot-like being that is mentally controlled by the original. If a Ganger is destroyed or gets mortally wounded, another Ganger is created for the consciousness to inhabit. Well, that's how it's supposed
to work, at least. In the episode they initially appear in, the Gangers are cut off from the originals, leading to them developing minds of their own (and retaining all of the original's memories), essentially turning them from avatars to clones. They immediately understand what has happened, and plot to escape the base, not particularly caring if the originals get killed in the process (after all, they aren't
actually different. At all
- 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. And eyes in one of the walls, made of more living Flesh.
- Chekhov's Gun: In "A Good Man Goes to War".
- Cloning Blues: They turn into this after being cut off from the people they're based on.
- Continuity Nod: In "The Almost People", one decommisioned Ganger resembles 9/10th Doctor villainess Cassandra.
- They also seem to be "forced-growth clones" like Chip.
- 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
- Glamour Failure
- 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. And 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.
- Replacement Goldfish: Two of the original humans are killed and their Gangers resume their lives for them.
- Rubber Man: The Gangers.
- Shapeshifting Squick
- Spot the Imposter
- Tomato in the Mirror
- 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.
- Your Princess Is in Another Castle: Or, Your Daughter is in Another Body, Rory.
The Boneless (Twelfth Doctor)
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.
- 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.
