[[folder: EXTERMINATE! ]]

Mutants. Cyborgs. Aliens. Xenophobia personified. Complete and utter bastards and the favorites of many small children. A species of genetically engineered creatures 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 MadScientist named Davros, the Daleks' physical form is shriveled and weak, but they 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 ''[[Recap/DoctorWhoS1E2TheDaleks the second serial]]'', in fact), they are the most endearingly and enduringly popular, and are considered to be The Doctor's collective [[ArchEnemy archenemy]].
* AbsoluteXenophobe: "[[/folder]]

[[folder: 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.
** [[Recap/DoctorWhoS35E2TheWitchsFamiliar How does a Dalek say]] "You are different from me"?
--> '''EXTERMINATE!'''
* AchillesHeel: The eye-stalk. "My vision is impaired! I cannot see!"
* AgeWithoutYouth: "The Witch's Familiar" reveals Daleks can't die naturally, but they do age, the body breaking down, rotting, decaying; when a Dalek reaches this point, they're consigned to the tunnels beneath Dalek cities without their armour. [[AndIMustScream There's a reason the Dalek word for "graveyard" is the same as the one for "sewer"]].
* AlwaysABiggerFish: The Doctor, who they refer to as "The Predator of the Daleks".
--> '''Eleventh Doctor''': 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''': [[/folder]]

[[folder: Emergency! Emergency! Weapon System Disabled! Emergency Protocols Have Been Breached! ''[[Madness Mantra 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.
--> '''Rose''': If you um... escaped the Time War don't you wanna know what happened. What happened to the Emperor?\\
'''Dalek''': [[/folder]]

[[folder: (Beat) The Emperor ''survived?!'' ]]
'''Rose''': [[BadassBoast 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.
* AlwaysChaoticEvil: Averted with Dalek Sec, Oswin Oswald, Rusty, and to a lesser extent Dalek Caan, who are or become good, but they are generally the exception that proves the rule. Also, none of them changed on their own. The overwhelming majority are genocidal death machines. {{Justified|Trope}} because they're genetically and mentally conditioned from birth to feel nothing but seething contempt for non-Dalek life, and fanatical obedience to the Dalek race.
* ArchEnemy: The species as a whole is this for the Doctor. Specifically, only the Eighth Doctor has never directly opposed them in the TV series[[note]]If you include the Expanded Universe, the Eighth has actually faced the Daleks ''more'' than any other Doctor[[/note]], largely due to having only two appearances, and even then, they make a voice-only cameo at the beginning of the TV movie. They're ''that'' ubiquitous.
* AttackItsWeakPoint: 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 WeaksauceWeakness 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.
* AxCrazy: Every single Dalek is a psychopathic KnightTemplar OmnicidalManiac. Even the "sane" ones realise what they are and tend to GoMadFromTheRevelation.
* BadassArmy: Nine times out of ten they surpass the humans in military capacity if the Doctor doesn't interfere.
* BadFuture: According to "Genesis of the Daleks" they would've eventually succeeded in their goal of destroying all non-Dalek life. Luckily the Fourth Doctor's meddling in their birth fixed all of that.
* BadIsGoodAndGoodIsBad: The only thing they find beautiful is pure hatred.
* BerserkButton: The Doctor eventually becomes this for them. Notably, the lone Dalek in "Dalek" stayed completely silent for 50 years, not saying a word to its human captors. But as soon as a man introduces himself to it as "The Doctor", the Dalek ''loses'' it.
-->'''Dalek:''' DOC-TOR? ''The'' Doctor? EXTERMINATE! EXTERMINATE! '''EXTERMINATE!'''
* BigBad: Archenemies of the Doctor and everything else. Quite fond of the EvilPlan in the revival, to the point where, during Creator/RussellTDavies' era, it was a surprise ''not'' to find them the masterminds behind the season's ApocalypseHow. They're the main antagonists of the 2005 and 2008 series.
* BigBadEnsemble: Of the 2006 series, with the Cybus Cybermen.
* BondVillainStupidity: All enemies of the Doctor suffer this to some extent, but the Daleks compound it with WrongGenreSavvy.
* BreakoutVillain: They very nearly never appeared at all, but are now at least as iconic as the TARDIS.
* BrokenRecord: Groups of Daleks are prone to chanting in unison, usually boasts or threats.
* CanonDisContinuity: Several bits of the Daleks' stories are continually discarded for one reason or another. This ranges from [[Recap/DoctorWhoS2E8TheChase the time the producers tried to make them comic relief]] to [[Recap/DoctorWhoS17E1DestinyOfTheDaleks that time the guy who made them forgot that they weren't robots]].
* CantUseStairs: A RunningGag for many years. Later stories established the Daleks as capable of flight, once the special effects were up to portraying it. This was first seen 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", the revived series episode that re-introduces the Daleks, 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.
* CatchPhrase:
** "I OBEY!"
** The phrase "Seek, Locate, Destroy." has become a distinct catchphrase over the years.
* CharacterisationMarchesOn: 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. That said, their first story takes place in the Daleks' past, before they had achieved space flight; it might simply have been a case of both their [[TechnologyMarchesOn Technology]] and society marching on in-universe. The BBC website for the classic series explains that these Daleks were Davros' early prototypes, and all the other Daleks were out in space building their empire.
* ColdBloodedTorture: 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.
* ColorCodedForYourConvenience:
** 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.
* TheComicallySerious: Despite them being xenophobic murderers, the fact that they have few emotions, including zero sense of humor, occasionally makes them this.
* ConservationOfNinjutsu: [[Recap/DoctorWhoS27E6Dalek One Dalek?]] You're so screwed. [[Recap/DoctorWhoS30E12TheStolenEarth A full]] [[Recap/DoctorWhoS30E13JourneysEnd Dalek]] [[Recap/DoctorWho2013CSTheTimeOfTheDoctor 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.
* CreepyMonotone: 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''.
* CruelAndUnusualDeath: That DeathRay they use? It doesn't just kill you. You die in agony.
* CyberCyclops: The production team has added pupils to the 2010 models, making the eye-stalk look almost organic.
* DeflectorShields: The revival gave them personal force-fields that can melt bullets before they even hit home. Even guns capable of destroying the [[ImmuneToBullets 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, [[EldritchAbomination Eldritch Abominations]], altering time itself - and not a single one of these attempts stopped them.
* DemotedToExtra:
** In the Classic Series, once Davros appeared the Daleks were demoted to being his mooks.
** In the Moffat Era, they are just a MonsterOfTheWeek instead of being the BigBad.
* TheDreaded: In a universe full of any number of beasties, [[Characters/DoctorWhoMasters 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 ''[[NamesToRunAwayFromReallyFast the Oncoming Storm]]''.
* EarlyInstallmentCharacterDesignDifference: They took three stories to achieve their classic appearance. The Dalek props in the first story, "[[Recap/DoctorWhoS1E2TheDaleks The Daleks]]", lack the vertical panels attached to the "shoulder" section of their casings. In "[[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth The Dalek Invasion of Earth]]", they have clunky looking satellite-style disc aerials on the backs of their casings, conceived [[AllThereInTheManual by the designers]] as a wireless power supply (the original Daleks had been unable to leave their city as they drew electrical life-support power from the floors). "[[Recap/DoctorWhoS2E8TheChase The Chase]]" added the final vertical panels, conceived as solar panels for power collection.
* EliteMook: The Special Weapons Dalek.
* EnemyCivilWar:
** 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.
* EverythingsBetterWithSpinning: Averted with Daleks, who have a tendency to spin around in circles before they blow up.
* EvilSoundsDeep: 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.
* EyeOnAStalk: A mechanical example; defeating them often revolves around [[GoForTheEye attacking it.]]
* TheFarmerAndTheViper: When facing their own defeat or perhaps simply wishing to gain an advantage, the Daleks often count on their foes being a GoodSamaritan and always cry [[SchmuckBait "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. After making it beg three times, she kills it.
* FeelingOppressedByTheirExistence: They feel this way about every single non-Dalek in the universe, and occasionally by Daleks of "inferior" designs also.
* FlyingSaucer: The standard make of their starships going back quite some time.
* ForeverWar: They are the result of a thousand year war between the Thals and their ancestors, and have been waging war [[OmnicidalManiac against the rest of the universe]] since their inception.
* FromNobodyToNightmare: In Doylist terms, though not Watsonian. In their first appearance, they were confined to a single city and trying to survive. Then they acquired space and later time travel, [[TheDreaded becoming one of the most powerful and feared races of all time.]]
* GoldColoredSuperiority: The rank structure of the Daleks places Golden Daleks high in the hierarchy.
* GoneHorriblyWrong: The original purpose of the Daleks was to provide a casing for the final Kaled mutation. Davros took this concept and turned it into something else.
* HumanResources: 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.
* ImmuneToBullets: 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.
* ImperialStormtrooperMarksmanshipAcademy: Inverted in the revived series. Unique among Doctor Who villains, the Daleks NEVER miss, even when shooting at the Doctor himself. Ascended into ImprobableAimingSkills in "Victory of the Daleks" where we see one shoot down airplanes.
* InLoveWithYourCarnage:
** They built the Dalek Asylum to contain Daleks that were too violent and insane even for ''them'' to control but 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 ''[[UpToEleven other]]'' prisoners.
** It's suggested that this might be the reason why they've never been able to finish off the Doctor.
* InferioritySuperiorityComplex: According to a documentary, actors are instructed to play the Daleks like this, the idea being that subconsciously the Dalek race as a whole are extremely troubled by the knowledge that they are really just mutants in tanks, feeling that they therefore are being dwarfed by other, more "legitimate" species. To make up for the resulting existential angst, they (over)compensate by deciding they must be better simply by virtue of them being Daleks.
* JokerImmunity: No matter how hard the Doctor tries, he can never manage to destroy the Daleks for good. They always end up resurfacing to face him again. Basically they're [[PopularityPower too iconic to kill off]].
** They've been completely wiped out countless times, and every time one group of them manages to defy odds and survive to revive the species again. 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. ([[CaptainObvious He has a time machine.]])
* KingMook: The Dalek Emperor is usually a Dalek mutant in gigantic casing.
* LackOfEmpathy: 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. That said, the fact they even ''have'' any concept of mercy is a plot-point in "The Witch's Familiar"; it turns out they get it from Davros, as they get so much else.
* LargeHam: "EXTERMINATE!" This is especially when voiced by NicholasBriggs.
* LaserGuidedAmnesia: Inflicted on all of them in "Asylum of the Daleks". It us 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.
** "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 the way back in "Genesis of the Daleks".
* {{Leitmotif}}: The appropriately titled [[https://www.youtube.com/watch?v=KR9MOS5r-RY "The Daleks"]] from the revival.
* LowCultureHighTech: Much like their [[ANaziByAnyOtherName 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 TimeTravel, but all they ever conceive of doing with their spaceships is find new places to raze.
* TheMan: The Dalek Emperor is this in the Series 1 finale, running not only the New Dalek Empire, but also secretly running the Human empire from behind the scenes, initially through the Editor and the Jagrafess, and later the Game Station and the [[ArcWords Bad Wolf corporation]].
* MassOhCrap: 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. ''[[HorrifyingTheHorror They're afraid of him.]]''
* MasterRace: As one Dalek says in "Victory of the Daleks", the fundamental basis and belief of their entire culture. "DALEKS ARE SUPREME!"
* MeatMoss: Thanks to AgeWithoutYouth, this is the ultimate fate of any Dalek that isn't killed in battle. They degrade into slime, still fully-conscious, and are left to line the walls of Dalek sewers.
* MindRape: "Into the Dalek" reveals that Dalek tech does this to them on purpose, to reinforce the notion of their OmnicidalManiac status. Any memory that might lead to a moral or existential epiphany is forcibly suppressed.
* MoralityDial: 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.
* ANaziByAnyOtherName: The [[SignificantAnagram Kaleds]], ancestors of the Daleks, wear [[PuttingOnTheReich black military uniforms very close to the standard Nazi uniform]], complete with faux-Iron Crosses at the neck, use what appear to be Luger pistols, 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 [[RecycledInSpace 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 [[Recap/DoctorWhoS30E13JourneysEnd "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 [[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth "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 [[UsefulNotes/DichterAndDenker thinkers and scientists]] before the whole Skarosian mutual extermination war got started and the fanatics 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.
** Their original enemies, the pacifist Thals, [[{{Irony}} were the Aryans the Nazis valued.]] The Daleks, on the other hand, [[TorturedMonster are the exact opposite of what Hitler would've wanted to be.]]
* NiceJobFixingItVillain:
** 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.
--> '''The Doctor''': The Doctor is not the Daleks.
* NighInvulnerability: 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).
** EnergyWeapons 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.
* NinjaZombiePirateRobot: Mutant Alien Cyborg Nazi.
* NoIndoorVoice: Even in normal conversation (or what passes as such for a Dalek), their voices are loud, harsh, and screeching.
* {{Omnicidal Maniac}}s: The only fitting fate for all non-Dalek life is death.
* OnceASeason: The BBC's deal with the Nation Estate means they have to appear in some form at least once a year in the Revival, 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 (the notable exception is the Eighth Doctor. The Daleks did appear in the TV movie but he didn't interact with him, but luckily Big Finish more than makes up for it).
* OneManArmy: 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.
* TheParanoiac: 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.
* RoarBeforeBeating: "EX-TER-MI-NATE!"
* ScaryDogmaticAliens: They're Nazis [[/folder]]

[[folder: In Space! ]]
, with the odd religious fundamentalist overtone, such as in "The Parting of the Ways".
** Witness Hitler-style salutes in "[[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth The Dalek Invasion of Earth]]" and remember that story was aired only 20 years after the end of the UsefulNotes/SecondWorldWar.
* SignificantAnagram: The Daleks were originally engineered from a race called the Kaleds.
* SpikesOfVillainy: Not on their cases, but ''on their DNA''.
* StarfishAliens: The Daleks inside their metal casings look like slimy, tentacled, sea creatures with one eye.
* StarfishRobots: The metal casings themselves are meant to house their creepy and mutated bodies.
* TheStarscream: 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. Though not smart enough to have realized that when he created a race that thinks they are superior to ''everyone'', that would include him. SubvertedTrope in the 2008 revival episode [[Recap/DoctorWhoS30E12TheStolenEarth "The Stolen Earth"]]; the Daleks don't even ''pretend'' to respect him this time, and are keeping him as a "pet".
* StrongAsTheyNeedToBe: Their DeathRay 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.
* SuperSoldier: 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, [[AllThereInTheManual according to the novelisation of "Remembrance of the Daleks",]] 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.
* TalkingLightbulb: Their "ear-lamps" flash in time with their speech.
* TechnologyMarchesOn: In-universe. One of the few species besides humanity that is depicted in different stages of their development - when we first saw them, before they reached space flight, they were dependent on external power sources. They had remedied this with disk-like accessories in the 22nd century, and engineered their casings to not even need these further ahead. They also achieved 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 occasionally ending up back on present!Earth.
* TooDumbToLive: They have an unfortunate habit of becoming this, particularly when their "[[/folder]]

[[folder: 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 [[Recap/DoctorWho20thASTheFiveDoctors "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 [[Recap/DoctorWhoS30E12TheStolenEarth "The Stolen Earth"]]. A Dalek's "eye" is blinded, but the Dalek remedies it and says "[[/folder]]

[[folder: My vision is not impaired. ]]
* TookALevelInBadAss: 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 [[OhCrap fly]].
** Their increase in threat level is most apparent when you see how the characters approach 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.
** This extends to the scale of their plans as well. While they have been {{Absolute Xenophobe}}s since their early years, this mostly extended to conquering planets and enslaving inferior races. In the Revival Series, they are full-on {{Omnicidal Maniac}}s who attempt to destroy ''all of reality'' at one point and nearly succeed.
* TorturedMonster: 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.
* ToServeMan: "Into the Dalek" reveals that Daleks feed on a protein goop processed from the carcasses of their victims.
* TurnedAgainstTheirMasters: They do this very often, mainly because Davros has no sense of pattern recognition.
* UnwillingRoboticisation: 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 51st century, in the form of their Dalek Puppets. These are significantly insidious in that they can function as [[ManchurianAgent Manchurian Agents]], acting like they did while alive, until an eyestalk unexpectedly bursts from their forehead...
* VillainDecay: 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".
** ZigZagged in the Moffat years. Under Davies they eventually became TooPowerfulToLive to the point where them merely being ''alive'' was a threat to the universe (and beyond), yet due to JokerImmunity they would always come back regardless. When Moffat took over the policy changed and they now show up as MonsterOfTheWeek, also preferring to try and use or kill The Doctor but no longer trying to destroy the universe, even trying to ''save'' it at some points (albeit only so they don't die too). Their technology and threat level is greater than ever, but they do not put it into practice.
* WeaksauceWeakness: Stairs used to be this for them. ''Used'' to.
* WorthyOpponent: 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 [[WhyDontYaJustShootHim inhibits them from killing him]], although the Dalek in question may just have been messing with the Doctor's head.
* WrongGenreSavvy: 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, [[IndyPloy there was never a plan to begin with]].
* XRaySparks: The special effect used for their DeathRay since 1988.

[[folder: Thals]]
!!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.
* ActualPacifist: After a thousand years of war, they refuse to fight the Daleks again.
* ArchEnemy: With the Kaleds. The war between the two races lasted a thousand years. They are also sometimes this to the [[ANaziByAnyOtherName Daleks]] but far less so than the Doctor.
* BeautyEqualsGoodness: The Thals resemble blond humans and are therefore good. The Daleks are blobs in metal tanks and are therefore evil.
* HumanAliens: Just like the Kaleds, they are visually indistinguishable from humans and Time Lords.
* NotSoDifferent: 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.
* PeopleOfHairColour: 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.
* TookALevelInKindness: 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.

[[folder: Sensorites]]
!!Sensorites (First Doctor)

A telepathic humanoid race native to the Sense Sphere. Appeared in "[[Recap/DoctorWhoS1E7TheSensorites The Sensorites]]".
* DittoAliens: 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.
* KlingonPromotion: If any of the Elders die, they will be replaced with another one who is next to the rank.
* WeaksauceWeakness: The race are prone to darkness and loud noise.
* YellowFace: They're based off of Chinese Communists.

[[folder: Zarbi]]
!!Zarbi (First Doctor)

Giant alien ants from the planet Vortis. Appeared in [[Recap/DoctorWhoS2E5TheWebPlanet The Web Planet]] and have shown up in the expanded universe a few times since, usually as a punchline.
* AntiVillain: The Zarbi are actually being brainwashed by [[EldritchAbomination the Animus.]]
* BigCreepyCrawlies
* BugWar: Uniquely, a war between two different factions of bugs. The ant-like Zarbi and the Menoptera, a race of butterfly people.
* InsectoidAliens: Planet Vortis is full of them. The Doctor and his companions are the only non-insects in the entire serial.
* MeaningfulName: Zarbi is a slang word in french for Bizarre. Bizarre means Weird when translated in English.
* PeopleInRubberSuits: ''Really'' obvious. A rather infamous example, meaning the Zarbi are somewhat of a joke among old-school fandom.
* RunningGag: Whilst the Doctor tangles with formidable foes such as [[OmnicidalManiac the Daleks]], [[TheAssimilator the Cybermen]] and [[ArchEnemy the Master]], {{Franchise/Iris Wildthyme}} keeps running into the Zarbi.[[/folder]]

!!Drahvins (First Doctor)

Beings from the Planet Drahva. They have very few men.
* AbsoluteXenophobe: Maaga and by implication all the other upper-caste Drahvins.
* AceCustom: The Drahvins are so wedded to their caste system that they self-destructively only give their leader caste the good weapons.
* BadBoss: Seems to be required by Drahvin law and/or custom.
* BeautyEqualsGoodness: Defied.
* BrainlessBeauty: The barely sentient Drahvin clones.
* TheCameo: River Song namedrops the Drahvins as members of the Alliance in "The Pandorica Opens".
* EvilCannotComprehendGood: The Drahvins can't understand self-sacrifice.
* FantasticCasteSystem: 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.
* LadyLand: 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, Tenth, Eleventh and Twelfth Doctors)
->'''Voiced by:''' Roy Skelton[[note]]Did not appear in "The Tomb of the Cybermen"[[/note]] and Peter Hawkins (1966–68); Peter Halliday (1968); Christopher Robbie and Melville Jones (1975); David Banks (1982–88); Mark Hardy (1982–83, 1988); William Kenton (1983); Michael Kilgarriff and John Ainley (1985); Brian Orrell (1985–88); Creator/NicholasBriggs (2006–present); David de Keyser (2012)

-->''"You belong to us. You shall be like us."''

The Mondas/Telos Cybermen come from the tenth planet of the Earth's solar system ("Earth's long-lost twin planet"). [[note]]Both the airdate, and the year the story was set in, were before IAU redefinition of what a planet is, so Pluto was still a planet then.[[/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 they have next to nothing living inside them, including emotions. Have been around for a while, first appearing in "[[Recap/DoctorWhoS4E2TheTenthPlanet The Tenth Planet]]" in 1966. Shown little consistency in appearance, other than usually having "handlebars" on the sides of their heads.

According to "The Doctor Falls", the Cybermen are essentially an inevitability, arising wherever there are people with the technology - Mondas, Telos, Planet 14, and so on.
* AcCENTUponTheWrongSylLABle: They spoke like this in their first appearance, giving their voices a rather unSETTling sINg-song quality.

[[folder: [[Silence You Fool SIII Ilen CE! ]]
[=AnyONNNNNNNNNNNNE=] who MOOOOOOOVES willbekilled inSTANTlyyyyyy!]]
* ActionFigureSpeech: Because their mouths don't move, they frequently move their hands when speaking amongst each other so the audience knows which one is talking.
* AdaptiveAbility: Ramped up in "[[Recap/DoctorWhoS33E12NightmareInSilver Nightmare in Silver]]", wherein they survive an electrified moat without a single loss, and eventually become immune to Cyberguns.
* AlwaysSecondBest: No matter how great a threat the Cybermen might be, if you put them in the same room/story as the Daleks, they'll inevitably be shoved aside as being weaker and less ruthless. The Daleks even mocked them about this in "Doomsday". This extends to real life as well, since the Cybermen are the second most well known ''Who'' monster.
* {{Animesque}}: Their 2013 incarnation takes some design cues from HumongousMecha anime, most notably their ''Franchise/{{Gundam}}''-like vented breastplates and ''Anime/NeonGenesisEvangelion''-inspired spinal detailing along their backs. From a non-anime perspective, they also look like as if they were the latest products of [[Film/IronMan Stark Industries]].
* ArchEnemy: Only second to the Daleks in being the most recurring and iconic antagonists to the Doctor.
* ArtEvolution: The Cybermen tend to change their look with each appearance. The only thing that ever remains unchanged is the handle bars on the side of the head.
* AssimilationPlot: Their whole shtick.
* TheAssimilator: Coupled with the UnwillingRoboticisation trope, and equally definitive.
* BodyHorror: Part and parcel of who they are. Played up by the original design, which had medical cloth surrounding their heads and ordinary human hands.
* CatchPhrase: "You belong to us" / "You will become like us", or variations upon those phrases. "WE MUZZT SURVIVE!" also tends to pop up fairly often.
** In "Nightmare In Silver", they get a new one: "Upgrade in progress."
* ChronicBackstabbingDisorder: The Cybermen will ''never'' hold up to their end of an alliance, instead being firm believers of YouHaveOutlivedYourUsefulness.
* ComicallyMissingThePoint: A dark version in "The Tenth Planet". Appalled that the Cybermen have no compassion or care for their victims, Polly poses the question: "Have you no heart?!" The Cyberman believes that she refers to the body part.

[[folder: [=Noo OO Ooo, that is OOONE of the WEA Knesses that we HAAAVE remo VED.= ]]
* ConspicuousGloves: The Mondasian Cybermen in "[[Recap/DoctorWhoS36E11WorldEnoughAndTime World Enough and Time]]" have gloves that resemble the skin of a Caucasian man, as opposed to being actual human hands, making it very useful for hiding the race of the actors. [[spoiler:Or indeed, that of the characters, i.e. Bill Potts.]]
* CostumeEvolution: They are one of the most frequently redesigned of ''Doctor Who'' aliens, with major new design changes being introduced in "The Moonbase" (the original BodyHorror design replaced by the sleeker and more robotic look of later ones), "The Invasion" (the introduction of the "square-headed" or "earmuff" look), "Earthshock" (in which the skin-tight look of the previous designs' external covering is replaced by a baggier look), and "Rise of the Cybermen" (a radical redesign in which their bodies externally appear to be covered with jointed armour rather than metallic cloth).
** According to some of the crew members who played the Cybermen in their debut story, they disliked the experience of wearing the costumes, hence the redesigns.
* CreativeSterility: Mentioned in the [[AudioPlay/BigFinishDoctorWho Big Finish audio production]] "Human Resources" where the Doctor informs the local Cybermen he only saved them by accident, before he realised who they were. When asked why he will extend help to all other species but not the Cybermen he answers "Because other species create. You don't."
* CreepyMonotone: All Cybermen talk in a mechanical, computer-like voice, though they shift in and out of this in their "Earthshock" appearance.
* CyberneticsEatYourSoul: Almost certainly the TropeCodifier. The Mondasians were simply trying to keep themselves alive via cybernetics, at the cost of their emotions, and it worked. Then their new, emotionless, cybernetic selves decided everyone else had to be like them, and set about trying to take over the universe. Going by "The Doctor Falls", something similar happens wherever they're created, regardless of whatever the initial motive was - they see themselves as an improvement over their original species, and decide everyone else must be "upgraded".
* DeathOfPersonality: People who are transformed into Cybermen are stripped of all personality and individuality, becoming soulless killers. Once a human is transformed, they're considered dead and all that can be done is to destroy the Cyberman. [[spoiler:Bill is an exception, for various reasons.]]
* TheDreaded: In "Nightmare in Silver". They inspire so much fear that the standard procedure for seeing one is to destroy the entire planet.
* EarlyInstallmentCharacterDesignDifference: The Cybermen in "The Tenth Planet" had a much more mixed human-robot appearance with heavy BodyHorror implications, while the later designs all look entirely or almost entirely (the 1980s design's chin window) robotic from the outside. Even when these Cybermen reappeared in Series 10, they looked different, with smaller headlights, tighter-fitting masks, and skin-colored gloves as opposed to human hands.
* EarlyInstallmentWeirdness: The first Cybermen in the series, in ''The Tenth Planet'', have individuality and, while incapable of true empathy, are at least not as openly malevolent and conquest driven as they would later become.
* EliteMooks: Cyber-Leaders, Cyber-Controllers.
* EvilEvolves: At least in "Nightmare in Silver", the main problem with fighting Cybermen is the ability to adapt to enemy weapons on the fly. Using a super laser gun thing Clara and some soldiers completely obliterated one Cyberman, blew up the head on the next and slightly singed a third. It's considered that the only way to really stop a Cyberman invasion is to nuke the entire planet. And even that may not be enough if TheStinger in [[TheEndOrIsIt that episode is any indication.]]
--> [[/folder]]

[[folder: Upgrade in Progress ]]
** Thanks to time dilation, the Cybermen of the Series 10 finale go through accelerated evolution, starting as Tenth Planet-like Cybermen and developing into the numerous versions seen over the series' history.
* EvilIsHammy:
** 1980s Cybermen, particularly their Cyber-Leaders. "EXCELLLEEENT!!!"
** Mr. Clever, who frankly considers [[ChewingTheScenery the scenery an appetizer]].
* {{Flanderization}}:
** When initially introduced, the Cybermen were completely alien but in many ways better than humans, even winning the arguments thrown at them, and offered cyber-conversion as a choice, although they couldn't care less about mankind. Later on, the Cybermen's main motto seems to completely become "convert everyone into Cybermen", although this could be excused by EarlyInstallmentWeirdness and that their survival motive seems to be intertwined with cyber-converting.
** In later Classic series stories, the Cybermen seem to be in a weaker state, which could explain their desire for more Cyber-conversion.
** The second flanderization Cybermen got was the level they displayed their emotions and their weakness to gold, because it clogs their chest-units. In "Revenge of the Cybermen", the weakness was introduced and the writers and actors put much less effort in making the Cybermen seem emotionless like they originally did. When they came back in "Earthshock", their lack of emotions was little more than lip-service and they had a tendency to delve into LargeHam territory, to the point it was suggested that the Cybermen remove all emotions except for rage. And in "Silver Nemesis", the gold weakness was exaggerated to the point where merely being hit by a gold coin could completely destroy them.
* GodzillaThreshold: After the Cyber-Wars, the mere presence of one Cyberman is grounds to blow up a whole planet. During the Cyber-Wars, the only way to stop them was to destroy their entire galaxy.
* GreatOffScreenWar: The Cyber-Wars, which ended with an entire ''galaxy'' being blown up. [[ImplacableMan They survived.]]
* HumanResources: It makes fighting them difficult. After all, if they need new troops, they can take ''you''.
* {{Hyperaffixation}}: They are notorious and sometimes mocked by fans for using "Cyber-" as a prefix for absolutely everything they make or use, such as using Cyberguns and Cyberbombs to fight Cyberwars, and travelling in Cyberfleets.
* IconicItem: The "handlebars" on their heads remain a constant part of their design, even as everything else changes. While in "The Tenth Planet" they seem to be providing power to their head lamps, the other designs seem to have no practical use for them. "World Enough and Time" explains them as being the Mondasian Cybermen's emotional inhibitor.
* JetPack: Both the 2013 and Mondasian variation have rocket boots.
* JokerImmunity: They've been wiped out several times, but there always turns out to be another batch of them stashed away somewhere on another planet that nobody had ever mentioned before. Or in another universe -- and ''those'' Cybermen have the immunity, too; at one point, every last one of them was sucked into a featureless void for eternity, and they still managed to come back. "The Doctor Falls" gives some justification to this by establishing them as a repeating pattern - even if they're wiped out, someone, somewhere, will end up recreating them.
* {{Leitmotif}}: "[[https://www.youtube.com/watch?v=of6ThsLtHqs Space Adventure]]" in the black and white era. [[https://www.youtube.com/watch?v=H5BfyzJm_zY "The Cybermen"]] in the revival.
* LiteralSurveillanceBug: The Cybermats.
* LongBusTrip: They hadn't returned in the Revival series until 2013, about 25 years. The Tenth Planet variants never came back until Series 10 of the new series.
* MachineMonotone: All Cybermen talk in a mechanical, computer-like voice, though they shift in and out of this in their "Earthshock" appearance.
* MachineWorship: How the Mondasian Cybermen got started, before deciding that everyone else should be like them too.
* MalevolentMugshot: Their logo design in the 60s and more recently in [[Recap/DoctorWhoTAGE02BloodOfTheCybermen "Blood of the Cybermen"]].
* MultipleChoicePast: While rising on Mondas is the most common origin for them, other media has also claimed they originated on Telos, Marinus (sometimes as a past Mondas), Planet 14, and a Mondasian colony ship. "The Doctor Falls" gets around this by claiming the Cybermen rose naturally on ''all'' of them -- they're the inevitable result of a combination of sufficient technology and insufficient caution.
* NewPowersAsThePlotDemands: The Cyberman in "The Pandorica Opens" shows several abilities that never appear before or after; the ability for the head to move and operate on its own, grow tentacles, shoot tranquilising darts, split open the face plate, and survive without any living organic components.
* TheNoseless: Although the Cybermen have been through numerous radical redesigns since their first appearance, this has always been a constant.
* ObliviouslyEvil: They genuinely think that UnwillingRoboticization is a favor for humanity.
* ScaryDogmaticAliens: Where the Daleks are an analogy for Nazi Germany, the Cybermen on the other hand are an analogy for Soviet Russia. They are hell-bent on surviving forever through the enforcement of unity by converting all other humanoid creatures into Cybermen like themselves, their only long-term goal being to keep carrying out this directive.
* SilentAntagonist: The "Nightmare in Silver" Cybermen don't say much.
* StompyMooks: The 2013 versions have this, just like the Cybus Cybermen. Even the original variants were given this trait.
* StrawVulcan: DependingOnTheWriter the emotionless qualities of the Cybermen are dropped if convenient.
* SuperSpeed: The ones that first appeared in "Nightmare in Silver" can move much faster than anything seen before, effectively graduating into LightningBruiser. Creator/MattSmith even commented that was the most scary thing about them in that story.
* TalkingLightbulb: The new series versions have blue lights in their mouth that flash as they speak, borrowed from their Cybus counterparts.
* TooDumbToLive: They locked the Doctor up in ''an explosives storage closet''... without searching him for items that could be used as a detonator. Guess how he got the door open?
* TookALevelInBadass: In "Nightmare in Silver", where they have since become equipped with an AdaptiveAbility, rendering them quickly immune to things that have previously destroyed or slowed them down. And to make it ''worse,'' they now have SuperSpeed that reaches BulletTime levels, and it requires special guns to even damage them.
** ''Worse'' for the Doctor, they aren't limited to assimilating Humans anymore, putting ''Time Lords'' on the menu.
** In their next appearance in "Dark Water"/"Death in Heaven" they have upgraded again, this time capable of flight, having advanced nanotechnology that can even ''resurrect and convert the dead'', and maybe or not finally capable of time-travel. Though this is due to being [[HijackedByGanon under Missy's control]]. The nanotech is so advanced that Missy's ultimate plan involves infesting the atmosphere of Earth with it until every living human and every human corpse becomes a Cyberman.
* UnwillingRoboticisation: In at least a couple episodes, forced conversion to Cybermen was announced as the fate for those captives who were "worthy" of the "honor", particularly the Doctor. Most notably in "[[Recap/DoctorWhoS5E1TheTombOfTheCybermen The Tomb of the Cybermen]]", where this fate was intended for all of the expedition team, as a "reward" for having re-awakened them.
* VocalEvolution: When the very first breed of Mondasian Cybermen reappeared in 2017, they retained the odd sing-song voices, but with the modern day vocal processing added (which had previously been used by Big Finish's depictions of them).
* WasOnceAMan: Wherever they begin, it follows a similar pattern: people use cybernetics to replace organic body parts, then someone decides to go all the way and make the entire body cybernetic, discarding humanity and emotion, and the Cybermen are created anew.
* WeaksauceWeakness: The infamous gold allergy evolved into this over time. It started as "gold dust jams up their works" and eventually became "you can kill them instantly with gold coins fired from a slingshot". This was quietly ignored in the RTD years (a tie-in site mentions that R&D eliminated the Cybus breed's allergy before they even started).
** However, in ''ComicBook/StarTrekTheNextGenerationDoctorWhoAssimilation2'', they were able to mostly defeat the Cybermen using gold dust, at Eleven's suggestion.
** In "Nightmare in Silver" it's mentioned as having been useful against older tech, but not even worth trying against new. Despite this, some models such as the Cyberplanner still contain the flaw deep within the source code for their operating systems, which the Doctor exploits, forcing it to spend time developing a patch.
* WellIntentionedExtremist: The original purpose of the Mondasian Cybermen was as a way to survive biosphere extinction, when a catastrophe threw Mondas out of orbit. To that end, they sacrificed their humanity to ensure their preservation, genuinely believing it to be the right thing to do. The Cybermen see themselves as a superior species (and they sorta ''are''), so cannot comprehend why people ''don't'' want to become like them. Furthermore, it's a very "us or them" kind of situation, and while the Cybermen intend to save as many humans as they possibly can, they acknowledge those they can't will die.
** The alternate universe counterparts were likewise created as a way to make humanity live ''forever''. Afterwards, they saw the decision to not upgrade as irrational and decided to remove choice from the equation entirely.

[[folder: Macra]]
!!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.
* AntiVillain: 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.
* DeadlyGas: Their primary food source.
* EvolutionaryLevels: After billions of years, the Macra the Tenth Doctor encounters on New Earth have devolved from sapient beings to mindless beasts.
* GiantEnemyCrab: Big enough to crush cars in their pincers.
* LongBusTrip: ''Forty years'' between "The Macra Terror" and "Gridlock".
* VillainDecay: 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.[[/folder]]

[[folder: Ice Warriors]]
!!Ice Warriors (Second, Third, Eleventh Doctor, and Twelfth Doctors)
->'''Played by:''' Creator/BernardBresslaw, 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:''' Creator/NicholasBriggs (2013)

A race of reptilian aliens who come from Mars, the Ice Warriors were the third species of big bads in ''Series/DoctorWho'' -- resulting in several appearances throughout the Second and Third Doctor eras... but they [[PutOnABus basically vanished]] with the end of the Third Doctor's run on the show in 1974 (around the time that space probes in RealLife 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 [[Recap/DoctorWho2005CSTheChristmasInvasion "The Christmas Invasion"]] and [[Recap/DoctorWhoS30E16TheWatersOfMars "The Waters of Mars"]], and finally made their return in the 2013 second half of series 7, during [[Recap/DoctorWhoS33E8ColdWar "Cold War"]].
* AnimatedArmor: They find leaving their armor deeply shameful, but if they are forced to do so they can remote-control it.
* BigBadEnsemble: 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.
* DisproportionateRetribution: 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.
* HeelRaceTurn: 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 ExpandedUniverse).
* [[LastOfHisKind 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 ExpandedUniverse puts the ''Doctor'' essentially at fault for said unspeakable event. Whoops. This appears to have been retconned as of [[Recap/DoctorWhoS33E8ColdWar "Cold War"]], with the Doctor saying Martians survive on other planets, and a Martian ship appearing at the episode's end. [[Recap/DoctorWhoS36E9EmpressOfMars "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.
* MightyGlacier / FragileSpeedster: 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.
* MonsterLord: 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.
* OhMyGods: They tend to swear by "the moons" (Phobos and Deimos).
* [[ProudWarriorRaceGuy Proud Warrior Race]]
** Subverted in the Literature/DoctorWhoNewAdventures novel ''The Dying Days'' where the Ice Warriors encountered there claim to be this but are psychotic monsters.
** PlayedStraight in "Empress of Mars" where they were only fighting because the humans attacked them first. After the commanding officer [[spoiler: 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 [[spoiler: she not only agrees, but spares his life, on the condition that he swears loyalty to her and the Ice Warriors. He agrees.]]
* PutOnABus: They basically vanished completely after 1974, but [[TheBusCameBack returned in the revival]] with 2013's "Cold War" and 2017's "Empress of Mars."
* RedEyesTakeWarning: Their armour has red-tinted lenses.
* TheReptilians
* {{Sssssnaketalk}}: They often speak like this due to them being reptilian.
* SuperSoldier
* ZombieGait: 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.

[[folder: Quarks]]
!!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 [[Recap/DoctorWhoS6E1TheDominators The Dominators]] and later showed up as independent villains of their own in [[TheSixties Sixties]] comic strips.
* CuteMachines: It looks like they just want a hug. The high pitched voices don't help.
* MechaMooks: For the planet conquering Dominators.
* MerchandiseDriven: 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.
* TinCanRobot:

[[folder: Krotons]]
!!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 {{Creator/Robert Holmes}}.
* BewareTheSillyOnes: In the Literature/EighthDoctorAdventures novel ''Alien Bodies'', a lone Kroton ''destroys an entire battleship full of Daleks.''
* MechanicalLifeforms: The Krotons resemble robots made of crystals.
* OurMonstersAreWeird: They have a TinCanRobot 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, MindRape people in order to get the power, breathe fluid through hose lines in their chest, and have inexplicable accents.
* StarfishAliens: Living crystals who resemble robots and power their spaceships with mental energy. Even by Doctor Who standards, they're pretty weird.
* WeakenedByTheLight: They have poor eyesight in daylight and so have trouble moving around. [[/folder]]

[[folder:Time Lords]]
!!Time Lords (Second, Third, Fourth, Fifth, Sixth, War, Tenth, Eleventh and Twelfth Doctors)
[[caption-width-right:160: The Fourth Doctor in Time Lord regalia.]]
->''"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..."''
-->-- '''Brother Lassar''', [[Recap/DoctorWhoS28E3SchoolReunion "School Reunion"]]

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 [[TimePolice guardians of the space-time continuum]], and (at least in the ExpandedUniverse) 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.
* ZeroPercentApprovalRating: 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.
* AbsoluteXenophobe: 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.
* AbusiveAlienParents: 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.
* AbusivePrecursors:
** 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.
* AbusingTheKardashevScaleForFunAndProfit: These dudes clock in as the TropeCodifier of Type 4 [[NotHyperbole according to Marnal]].
* AlienNonInterferenceClause: 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.
* AntiVillain: 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 ''Series/DoctorWho'', up until the present, has portrayed them very inconsistently, sometimes as good, sometimes as evil and often as something in-between.)
* AscendToAHigherPlaneOfExistence: 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.
* AwakeningTheSleepingGiant: 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. [[OhCrap And then the war]] [[FantasticNuke went temporal.]]
* BigBrotherIsWatching: "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.
* BlueAndOrangeMorality: They do on some occasions express a view of life as something to be preserved, yet they obey their AlienNonInterferenceClause without hesitation.
* BodyHorror: 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.
* BreakTheHaughty: The Time War brought a HigherTechSpecies to their ''knees''.
* CantArgueWithElves: 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 MoralityChain in his companions.
* CorruptBureaucrat: 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.
* CrystalSpiresAndTogas: On the surface with their gorgeous Citadel and fancy regalia. But scratch it and you find a DeadlyDecadentCourt, where "simple palace revolutions" are the norm.
* DependingOnTheWriter:
** Are they a basically well-intentioned HigherTechSpecies devoid of sympathy for individual lesser beings ("The War Games"), uncomplicatedly good protectors of the universe ("The Three Doctors"), [[TheManBehindTheCurtain 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 DeadlyDecadentCourt ("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.
* TheDreaded: 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 OhCrap, 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'' BigBad of 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.
* DyingRace: 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, [[Recap/DoctorWhoS30E6TheDoctorsDaughter Jenny]] (who's currently [[WhatHappenedToTheMouse MIA]]), [[Recap/DoctorWhoS30E9ForestOfTheDead River Song]] (who's [[TimeyWimeyBall sort]] [[VirtualGhost of]] dead), and the Master, [[JokerImmunity 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 [[WhatHappenedToTheMouse what happened]] to Susan after [[Recap/BigFinishDoctorWhoNEDAS4E10ToTheDeath 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.
* EveryoneHasStandards: 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.
* FaceHeelTurn: Between "The Trial of a Time Lord" and the Time War scenes of "The End of Time", the Time Lords become [[KnightTemplar 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 [[PunchClockVillain 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.
* FantasticCasteSystem: 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.
* GenderBender: 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.
** [[Characters/DoctorWhoVillains Borusa]] is also implied to have had a female form at some point in his past in ''[[Recap/NewSeriesAdventuresEnginesOfWar 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.
** In "[[Recap/DoctorWhoS35E12HellBent 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.
* GoodIsNotNice: 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.
* HeWhoFightsMonsters: 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 OmnicidalManiac Daleks they had been fighting.
** "The Day of the Doctor" reveals that in the face of the Daleks assault, the military had [[GodzillaThreshold 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''.
* HealingFactor: 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.
* HigherTechSpecies: They are ''the'' higher tech species. A vehicle that can travel anywhere in time and space, be BiggerOnTheInside and disguise itself as anything around it as well as generating food and drink for its whole crew... is laughably primitive by their standards.
* HumanAliens:
** 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 Franchise/DoctorWhoExpandedUniverse, they're the reason so many Franchise/{{Whoniverse}} species are human-looking.
* HumanOutsideAlienInside: On the surface they (usually) look human, but underneath everything's different.
* IMeantToDoThat:
** 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.
* ImpossiblyTackyClothes: 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 WTHCostumingDepartment territory. Most just skip the whole "spot the odd thing out" option and go straight to full-on eye-bleed.
* LastOfHisKind: The Doctor, due to having wiped the others out at the end of the Time War. Or so he believed.
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=k-SBNgu1hO4 "This Is Gallifrey"]], which acts as the theme to both the planet Gallifrey and the Time Lords themselves.
* MercyInvincibility: 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.
* MysticalHighCollar:
** Their formal robes have massive notoriously collars.
** Hilariously, a FreezeFrameBonus from John Smith's Journal in "Human Nature" reveals that the Doctor, in his youth, "could never get the collar right".
* NeverSpeakIllOfTheDead:
** 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".
* NiceHat: In "[[Recap/DoctorWhoS14E3TheDeadlyAssassin 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.
* NoManShouldHaveThisPower: The abuse of their power in the past is why they developed their AlienNonInterferenceClause - officially. Subverted in that the High Council is more then willing to abuse their power when they see fit.
* OmnicidalManiac: Their plan in "The End of Time" involves the destruction of time itself.
* TheOmniscientCouncilOfVagueness: They tended to be this or the NotSoOmniscientCouncilOfBickering, which is why RTD drop-kicked them out of the revived show.
* PetTheDog: In "Time of the Doctor", the Time Lords used the cracks in the universe 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.
* ThePhilosopherKing: The Time Lords' entire hierarchy is based on academia, with everyone belonging to a specific College. Training at the Academy begins as age 8.
* Really700YearsOld: A single Time Lord regeneration can, with proper care and attention, last for hundreds of years, sometimes more.
%%* ScrewTheRulesIMakeThem: The Time Lords aren't shy about letting other races know this.
* SmugSnake: 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.
* SnobsVsSlobs: 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.
* SpaceElves: Long-lived, scholarly, reclusive, ancient, frequently haughty, devious, powerful and usually robed.
* SpareBodyParts: 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.
* SufficientlyAdvancedAlien: As a result of being ''the'' HigherTechSpecies. Even the Daleks, their most dangerous foe, never came close to matching the Time Lord's skill at time travel and [[BiggerOnTheInside transcendental]] technology.
* ThatManIsDead: 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.
* TrainingFromHell: At the age of eight, Time Lords attending the Academy are taken in front of the [[EldritchLocation Untempered Schism]], a gap in the fabric of reality in which the entire Time Vortex can be seen. According to the Doctor, "Some would [[TheMuse be inspired]], some would [[ScrewThisImOuttaHere run away]], and some would [[MySkullRunnethOver 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.
* UngratefulBastard: 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 High Council are these, the rest of Gallifrey are certainly not.
* WellIntentionedExtremist: 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. [[JumpingOffTheSlipperySlope This led them down a very dark path]].

[[folder: Autons]]
!!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), Creator/ArthurDarvill (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... [[ManchurianAgent and may even believe their own cover story]].
* AnimateInanimateObject: So long as it's made of plastic, the Nestenes can bring it to life and kill people with it.
* ArmCannon: Well, hand cannon.
* BreakoutVillain: 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.
* EverythingTryingToKillYou: As the Third Doctor's tenure was largely confined to the UsefulNotes/HomeCounties in the present day for budget reasons, the Autons inaugurated the grand old ''Doctor Who'' tradition of everyday objects trying to kill you.
* HiveMind
* ImmuneToBullets: The original versions helped inaugurate a long tradition of UNIT's guns being ''utterly useless'' against the threat of the week.
* ManchurianAgent: Some later model Autons come with fake memories.
* MayContainEvil
* {{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.
* MurderousMannequin
* [[RidiculouslyHumanRobots Ridiculously Human Duplicates]]: Some of them are created as UncannyValley 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).
* StepThreeProfit: In the [[http://www.dailymotion.com/video/x15cw41_doctor-who-the-doctors-revisited-the-third-doctor-jon-pertwee_tech Doctors Revisited - Jon Pertwee]] special, Creator/StevenMoffat 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, [[CrazyAwesome completely bonkers]].
* UncannyValley: 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.

[[folder: Homo Reptilia]]
!!Homo reptilia [[note]]Also known as Silurians and (briefly) Eocenes. The aquatic variant are called Sea Devils. Collectively, they have been called Earth Reptiles.[[/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 [=McIntosh=][[note]]Did not appear in "The Pandorica Opens"[[/note]] (2010–present) and Richard Hope (2010–12),[[note]]Did not appear in "The Pandorica Opens" or "A Good Man Goes to War"[[/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."''
-->-- '''Alaya'''

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. [[Recap/DoctorWhoS7E2DoctorWhoAndTheSilurians It]] [[Recap/DoctorWhoS9E3TheSeaDevils never]] [[Recap/DoctorWhoS21E1WarriorsOfTheDeep ends]] [[Recap/DoctorWhoS31E8TheHungryEarth 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 [[MultipurposeTongue 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).
* TheArk: 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.
* AttackAnimal: 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 [[strike:a pantomime horse]] an unknown deep-sea creature.)
* BeneathTheEarth: They have laid dormant there for millions of years, and possess very advanced technology.
* BlueAndOrangeMorality: 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.
* TheCameo: In "The Pandorica Opens" they are members of the Alliance, and watch as the Doctor is dragged to the Pandorica.
* ExtraEyes: 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 [[Recap/DoctorWhoS31E8TheHungryEarth "The Hungry Earth"]] / [[Recap/DoctorWhoS31E9ColdBlood "Cold Blood"]] and [[Recap/DoctorWhoS32E7AGoodManGoesToWar "A Good Man Goes to War"]], who are [[HandWave handwaved]] as being a different branch of the same species, somewhat analogous to the difference between Humans and Neanderthals.
* EverythingsBetterWithSamurai: An elite task force of Sea Devils called Elite Group One was dressed in secure, samurai-style armor
** KatanasAreJustBetter: Perhaps as a subtle nod to the above, Madame Vastra wields one of these as her WeaponOfChoice.
* ExposedExtraterrestrials: 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".
* FantasticRacism: 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.
* InsistentTerminology: They refer to Gene Lines rather than families, and some [[FantasticRacism other touches]].
* KillEmAll: 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.
* [[LastOfHisKind 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", [[BerserkButton 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.
* LizardFolk: They are an ancient race of reptilian humanoids that predate humans.
* MoreDeadlyThanTheMale: Since their reappearance in 2010, the female Silurians have been portrayed as more aggressive than the males. Much like real-life lizards, then.
* MultipurposeTongue: Useful both for defending oneself and... [[PowerPerversionPotential um]]...
* NonMammalMammaries: Well... the modern ones have them, anyhow.
* NotEvilJustMisunderstood: 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.
* OverlyLongTongue: Which are capable of stunning an opponent upon contact.
* ProudWarriorRace:
** 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.
* PsychicPowers: 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.
* RageHelm: The warrior caste Silurian faceplates are organic in appearance, and could easily be mistaken as a real (albeit scarier) face.
* RedScare: "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 WordOfGod. The Sea Devils may have been this as well, but it doesn't seem as likely.
* TheReptilians: Although they are actually native inhabitants of the Earth.
* TaxonomicTermConfusion: ''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.
* UndergroundCity: Have made a very impressive one where they remain in hibernation.
* UnderwaterBase: 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 [[Recap/DoctorWhoS8E3TheClawsOfAxos The Claws of Axos.]] They were defeated by the Third Doctor and UNIT. The Axons have also shown up in {{AudioPlay/Big Finish Doctor Who}} (where they fought the Sixth Doctor) and the comic strip of {{Magazine/Doctor Who Magazine}} (where they battled the Eleventh Doctor and Amy Pond in Japan.)
* BeautyEqualsGoodness: Subverted. They appear as golden angelic humanoids but turn out to be monstrous.
* GlamRock: The aesthetics of glam rock had a very big influence on the look of the Axons. It was the early Seventies, after all.
* HiveMind: The seemingly individual Axons are all part of the same entity.
* LightIsNotGood: Gold and orange are the Axons' primary colour palette and they turn out to be evil.
* OrganicTechnology: The spaceship they arrive to Earth in. Considering that even the ship is part of the Axos hive mind, this makes sense.
* TrojanHorse: 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.[[/folder]]

[[folder: Ogrons]]
!!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.
* DumbMuscle: Ogrons are very strong and very stupid.
* KillerSpaceMonkey: Extremely strong and brutal.
* {{Mooks}}: For the Daleks and the Master.
* ServantRace: Are this to the Daleks. However IDW Comics seems to show them more as [[PunchClockVillain Punch Clock Villains]].
* ShoutOut: The name may be derived from the mythological creatures ogres. [[/folder]]

[[folder: Peladonians]]
!!Peladonians (Third Doctor)

The Peladonians (or Pels) were a race of near-humans native to the planet Peladon who retained a feudal culture.
* AlienSky: Their planet was known for being especially stormy. Dangers from the wind and rain were constant.
* FeudalFuture
* HumanAlien
** AmbiguouslyHuman: 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 ''Series/DoctorWho'', humans can [[Recap/DoctorWhoS28E1NewEarth breed with cats]].
* SkunkStripe: One of the few ways to tell them apart from humans was the burgundy streak through their hair.
* [[GreenRocks 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.

[[folder: Draconians]]
!!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.
* FantasticSlur: Some humans call them "Dragons."
* FeudalFuture: 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.
* NonMammalianHair
* ReasonableAuthorityFigure: The Emperor.
* TheReptilians
* SnakeTalk: 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.[[/folder]]

[[folder: Sontarans]]
!!Sontarans (Third, Fourth, Sixth, Tenth, Eleventh and Twelfth Doctors)

-->''"Sontar HA! Sontar HA! Sontar HA!"''

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 usually somehow tied to their never ending war against the Rutans (a race of... intergalactic jellyfish).
* AffablyEvil / FauxAffablyEvil: 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 AxCrazy 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 AffablyEvil 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 ForTheEvulz.
* AsskickingEqualsAuthority: Those in power? They fought their way up there.
* AttackItsWeakPoint: 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.
* AuthorAppeal: Their entire creation was to appeal to author Creator/RobertHolmes and his distaste of militarism and colonialism. Also a bit of a TakeThat against America at times, according to some people.
* BadassBoast: They tend to do this.
* BaldOfAwesome / BaldOfEvil: In equal amounts.
* BloodKnight: 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.
* BlueAndOrangeMorality: 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.
* ChildSoldiers: Twelve is considered a ripe old age for Sontarans.
* CloneArmy: The existence of different "batches" is used to explain why they're not 100% identical.
* CombatMedic: Considered a FateWorseThanDeath by them for obvious reasons. ([[Recap/DoctorWhoS32E7AGoodManGoesToWar That's not to say they can't be good at it, though.]])
* DefeatMeansRespect: Part of their AsskickingEqualsAuthority 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 YourApprovalFillsMeWithShame, as the Doctor doesn't like to think of himself as a military leader.
* DeathSeeker
* DittoAliens
-->'''Rattigan:''' How do you tell each other apart?\\
'''Stahl:''' We say the same of humans.
* ForeverWar: Their never ending war with the Rutans. Last time we heard, it wasn't going in the Sontaran's favor.
* GeniusBruiser: 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.
* HonorBeforeReason: 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.
** They admire this trait in humans, going by Commander Skorr's final word ("Wonderful..."), after [[ColonelBadass Colonel]] [[OfficerAndAGentleman Mace]] challenges him in the corridor ("You will face me, sir!"), before shooting him.
* LargeHam: They are well known for their bombastic speeches and "come at me, bro" attitude, which accounts for much of their popularity.
* LawfulStupidChaoticStupid: 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 "[[Recap/DoctorWhoS22E4TheTwoDoctors 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.
* LiteralMinded: 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.
* TheMagnificent: High-ranking Sontarans tend to carry such epithets, e.g. General Stahl the Undefeated, Commander Skorr the Bloodbringer, etc
* MartyrdomCulture: "Wonderful..."
* OneGenderRace:
** 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.
* [[ProudWarriorRaceGuy Proud Warrior Race Guys]]: The Doctor Who representatives of the trope.
* SociopathicSoldier: They live for war. They die for war. God help you if you get in their way or fight back.
** Subverted in "[[Recap/DoctorWhoS32E7AGoodManGoesToWar A Good Man Goes To War]]" by Strax the CombatMedic - 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.
--> '''Strax''': ''[cheerfully]'' I hope someday to meet you in glory of battle where I will crush the life from your worthless human form. ''[[MoodWhiplash Try and get some rest]]''.
** Stomm (see above) says farewell to the Doctor in a similar manner.
* SpheroidDropship: Almost ''all'' their ships are plain spheres.
* StaffOfAuthority: The Sontaran baton is a device is carried by certain high ranking officers of the Sontaran Empire symbolizing rank as well as being functional.
%%* SuperSoldier:
* ViolentGlaswegian: 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.
* YoungerThanTheyLook: 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 [[/folder]]
[[folder: Wirrn]]
!!Wirrn (Fourth Doctor)

The Wirrn were a race of huge, parasitic insects. They initially appeared in "[[Recap/DoctorWhoS12E2TheArkInSpace The Ark in Space]]" and have shown up in AudioPlay/BigFinishDoctorWho as well.
* BigCreepyCrawlies: The Wirrn stand at around 6-7 feet tall. Not too shabby for an insect race.
* BodyHorror: You slowly and painfully begin turning into one of them once a Wirrn stings you.
* TheCameo: A dead Wirrn has a brief appearance in the [[Recap/DoctorWhoS16E3TheStonesOfBlood The Stones of Blood.]]
* DyingRace: Their main hives have been wiped out, leaving them desperate.
* FightingFromTheInside: Like many infectious Doctor Who monsters, their victims can fight back with strong willpower and emotions.
* InsectoidAliens: They resemble enormous wasp/ant hybrids.
* ItsPersonal: 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.
* OffTheShelfFX: 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, [[Recap/DoctorWhoS34E8MummyOnTheOrientExpress when Clara Oswald finds a Sarcophagus full of green bubblewrap.]]
* TheVirus: 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.[[/folder]]

[[folder: Kaleds]]
!!Kaleds (Fourth and Twelfth Doctors)

A species of humanoid aliens and the ancestors of the Daleks who use to inhabit the planet Skaro. They got into a thousand year war with the Thals that nearly decimated both species. The Kaleds were beginning to mutate due to chemical weapons and the Daleks were originally designed as a travel machine for the final mutation. Originally they died from a nuclear bomb, but the Fourth Doctor's meddling in their timeline meant the majority were killed by a Thal rocket and the early Daleks. Davros is currently the only Kaled current living.
* AbusivePrecursors: The Daleks inherited their racist beliefs and a ruined Skaro from them.
* BizarreAlienBiology: On the outside, Kaleds look human. On the inside, they're different enough that a Kaled scientist is utterly baffled when looking at med-scans of the Fourth Doctor and Harry.
* EvenEvilHasStandards: They were overtly based on Nazis, intended genocide on their Thal rivals, and used chemical and biological weapons to the point that Skaro was virtually uninhabitable. But even they were appalled by Daleks, a creature genetically engineered to have no sense of right and wrong.
* FantasticRacism: They '''''hated''''' the Thals to point they wanted to commit genocide; the Thals returned the feeling. They also look down on anybody mutated.
--> '''Nyder:''' We must keep the Kaled race pure. Imperfects are rejected.
* ForeverWar: They were engaged in a mutually self-destructive war with the Thals; we never find out why they're at war with other only that both sides saw the total destruction of each other as the only viable way for peace.
* HopelessWar: Regardless of which side won, there wasn't much victory to be had. Skaro was a burnt out irradiate mess, and resources and technology was so limited soldiers were practically down to fighting with bows and arrows. On top of that, the entire Kaled population was crammed into one city, so they didn't really have the numbers to keep going anyway.
* HumanoidAlien: They look like humans with brown or dark hair; the Thals have blonde hair.
* {{Hypocrite}} They look down on mutants and are big believers in racial purity, and yet their chief scientist Davros was crippled and mutated into something only vaguely human and it did nothing to lower his standing in Kaled society.
* IgnorantOfTheirOwnIgnorance: Thanks to Davros' word being the be-all-and-end-all of Kaled science, they believed that there were only seven galaxies, and that of them Skaro was the only planet capable of supporting life.
-->'''Fourth Doctor:''' But's it's a known fact that there are more than seven galaxies.
-->'''Ronson:''' ''(humouring him)'' ... Quite.
* KillEmAll: When the Doctor convinced the Kaled leadership into investigating Davros, he gave the Thals the means to destroy the last Kaled city. Then he had the Daleks wipe out any remaining Kaleds who weren't loyal to him, only for the Daleks to go on to kill the rest of the Kaleds for good measure.
* NoodleIncident: We never find out ''why'' the Kaleds and Thals are engaged in war. It makes the conflict even scarier.
* NotSoDifferent: The Kaleds were militant fascistic xenophobes, fighting a war against the Thals, who were also militant fascistic xenophobes... the only real difference was that Kaleds wore black military uniforms and the Thals wore green jumpsuits.
* PunchClockVillain: Despite their racist society, there were a handful of Kaleds who weren't totally evil only doing their duty in war and desperately wanted peace. It didn't save them from the Daleks or Davros.
* PuttingOnTheReich: Kaled culture is very similar to Nazi Germany right down to an unhealthy obsession with keeping their race pure.
* {{RetCon}}: Originally the ancestors of the Daleks were called Dals. The BBC website for the Classic Series clarifies this was a slur that became the official name due to incomplete Thal records.
* SmallRoleBigImpact: They only had a major role in one Fourth Doctor story (and a cameo in the Series 9 premiere) but they are essential to the ''Doctor Who'' mythos, because without them there would be no Daleks.

[[folder: Zygons]]
!!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. {{Creator/David Tennant}} has named the Zygons as his favourite Doctor Who monsters.
* AlwaysChaoticEvil: Averted. Most of the Zygons living on Earth just want to live in peace and at worst are PunchClockVillains for Zygon High Command.
* AntiVillain: Their home planet was destroyed so they understandably seek a new one. Unfortunately, they want Earth, an already inhabited planet.
* AttackAnimal: 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.
* TheCameo: In "Attack of the Graske" (a Tenth Doctor mini-sode) and "The Power of Three", albeit in human guises in the latter.
* FatalFlaw: Their arrogance proves their undoing in "The Day of the Doctor".
* {{Foreshadowing}}/CerebusRetcon: 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.
* LongBusTrip: 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.
* OrganicTechnology: 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.
* PoisonousPerson: They can poison humans with a touch. They also have, as the Tenth Doctor would attest, venom sacs in their tongues.
* ShapeshifterBaggage: 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.
* ShockAndAwe: 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.
* StockNessMonster: One of their Skarasens lived in Loch Ness for centuries and inspired the legend.
* TheyLookLikeUsNow: The Zygons' ability to assume human form is what makes them so paranoia-inducing.
* UnderestimatingBadassery: 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!''
* VoluntaryShapeshifting: 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."

[[folder: 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.
* AmbiguousSituation: 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 they have similar mental powers like telepathy, but their powers are stronger than the Time Lords are.
* HumanoidAlien: One of many in the Whoinverse.
* LadyInRed: All of them wear red robes and habits.
* LadyLand: There are no male life-forms on Karn.
* LivingProp: Ohilia is the only member who speaks, the rest are literally props who just stand around.
* MagicVersusScience: ''Literature/ABriefHistoryOfTimeLords'' suggest this is the reason why they left Gallifrey as the increasing scientific-minded Time Lords were beginning to be dismissive of the Cult's mystic beliefs. 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.
* Really700YearsOld: Their Elixir grants immortally, but only within vicinity of the Flame; try to drink it off Karn and it's useless.
* SmallRoleBigImpact: 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.
* SplinterCell: They used to live on Gallifrey before having a disagreement with the Time Lords.
* WeUsedToBeFriends: The Time War really strained relations with their Time Lord cousins.

[[folder: Krynoid]]
!!Krynoid (Fourth Doctor)

Carnivorous alien plants with big appetites. First showed up in [[Recap/DoctorWhoS13E6TheSeedsOfDoom "The Seeds of Doom"]] and have popped up in AudioPlay/BigFinishDoctorWho a few times since. A Krynoid also faced off against the Eleventh Doctor in the e-book ''Tales of Trenzalore.''
* AlienKudzu: It infests entire planets.
* BodyHorror: Their victims slowly start turning into giant plant creatures.
* CombatTentacles: As Mary Whitehouse put it: "Strangulation by obscene vegetable matter."
* GreenThumb: Krynoids have the ability to telepathically control nearby plant life.
* ManEatingPlant
* PaletteSwap: The Krynoid costumes are just Axon (in their true form) costumes painted green instead of orange.
* PlantAliens
* TheVirus: When a Krynoid lands on a planet, it will consume all animal life to create more of itself.
* WhenTreesAttack: The Krynoid's ability to control plant life leads to this. [[/folder]]

[[folder: Rutans]]
!!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.
* ArchEnemy: To the Sontarans.
* ElectricJellyfish: Pretty much a space version of this.
* FaceStealer: 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.
* ForeverWar: 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.
* TheGhost: 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 [[Recap/DoctorWhoTAGE05TheGunpowderPlot Eleventh Doctor Adventure game]], a very short StoryArc with the Fifth Doctor in BigFinishDoctorWho, etc), but appear nowhere ''near'' as much as the Sontarans.
* InsignificantLittleBluePlanet: 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.
* SicklyGreenGlow
* VoluntaryShapeshifting: With great effort.[[/folder]]

[[folder: Movellans]]
!!Movellans (Fourth Doctor and Twelfth Doctor)
--> ''"We are infinitely superior."''

The Movellans were androids who warred with the Dalek Empire.
* AchillesHeel: 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.
* DeceptivelyHumanRobots: 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.
* LongBusTrip: [[UnexpectedCharacter 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.[[/folder]]

!!Nimons (Fourth Doctor)
->'''Voiced by:''' Clifford Norgate (1979-80)

-->-- '''Soldeed'''

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 "[[Recap/DoctorWhoS17E5TheHornsOfNimon The Horns of Nimon]]", but the Nimons also made a memorable appearance in AudioPlay/BigFinishDoctorWho and were alluded to in the revived series episode "[[Recap/DoctorWhoS32E11TheGodComplex The God Complex]]".
* EvilSoundsDeep: They have deep, booming voices.
* FrickinLaserBeams: Uniquely, the Nimons fire lasers out of their horns.
* GodGuise: Their modus operandi when it comes to their invasion plans.
* LargeHam: "The Horns of Nimon" is so full of hammy acting it would offend Israel, and the Nimons themselves are no exception.
* LifeDrain: How they feed. It leaves people, and entire planets, as desiccated husks.
* ALoadOfBull: The Nimons greatly resemble the Minotaur of Greek myth.
* MilkingTheGiantCow: The actors in the Nimon costumes are ''really'' going for it. Oh, and [[IncrediblyLamePun no jokes about "giant cows."]]
* RedAndBlackAndEvilAllOver: Black fur/skin with bright red eyes.
* UnrealisticBlackHole: The Nimons use black holes to power their technology and as wormholes to travel the universe.[[/folder]]

!!Trions (Fifth Doctor)
Trions are an alien species that the Fifth Doctor's companion Turlough belongs to.
* DeepCoverAgent: According to Turlough, the Trions had undercover agents on every civilized planet, including Earth.
* HumanAlien: 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.
* BlueAndOrangeMorality: The Eternals shown in "[[Recap/DoctorWhoS20E5Enlightenment 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.
* CompleteImmortality: 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 ''Magazine/DoctorWhoMagazine'' comic ''Uninvited Guest'', the Seventh Doctor might have found a loophole.
* EldritchAbomination: Exist outside of time and space in eternity, have great RealityWarper powers and they are to ''Time Lords'' what Time Lords are to other races.
* ForTheEvulz: As shown in the ''Magazine/DoctorWhoMagazine'' story ''Uninvited Guest'', the more sadistic Eternals would sometimes pose as gods and doom whole worlds in the process.
* ScrewThisImOutOfHere: [[AllThereInTheManual Supplemental material]] states they left reality after the Time War and never came back.
* SealedEvilInACan: 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).
* WhoWantsToLiveForever: 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

[[folder: The Gelth]]
!! 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.
* FalseInnocenceTrick: 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.
* InvadingRefugees: The Gelth were fleeing the Time War.
* NightmareFace: Behold◊
* NotUsingTheZWord: 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.
* RedEyesTakeWarning: 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.
* UnfortunateImplications: 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.


[[folder: Slitheen]]
!!The Slitheen family[[note]]"The Slitheen" for short; their race is called Raxacoricofallapatorian[[/note]] (Ninth Doctor)
->'''Played'''[[note]]in their human skins, not the prosthetic[[/note]] '''by:''' Annette Badland, David Verrey, Rupert Vansittart, Eric Potts and Steve Spiers (2005)

->''"Victory should be naked!"''
-->-- '''Jocrassa Fel-Fotch Passameer-Day Slitheen'''

The first recurring aliens original to the revitalized ''Series/DoctorWho'' franchise, the Slitheen are basically a family of Used Car Dealers and [[ConMan Con Men]]. [[/folder]]

[[folder: [[Recycled INSPACE 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 AlwaysChaoticEvil ''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 ''Series/TheSarahJaneAdventures'', 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.
* AffablyEvil: 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.
* AlwaysChaoticEvil: Subverted-we're led to believe they're just another invading species, but they're actually a criminal syndicate. [[MySpeciesDothProtestTooMuch Raxacoricofallapatorians are rather peaceful.]]
* BecomingTheMask: 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 [[GoingNative gone native]] after six months amongst the Welsh, while the latter regrets having to ditch his old skin suit, as he got to have "[[ReallyGetsAround a wife, a mistress]] [[BiTheWay and a young farmer]]".
* BizarreAlienBiology: 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.
* CostumesChangeYourSize: [[JustifiedTrope Justified]] with their technology, allowing them to fit inside of their tinier human disguises.
* CruelAndUnusualDeath: 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.
* EgomaniacHunter: The Slitheen family, at least, enjoy hunting and treat it like a ritual.
* EvenEvilHasLovedOnes: 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.
* EvilHasABadSenseOfHumor: 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.
* EvilPlan: The family Slitheen seems to be rather good at vile schemes to enrich themselves. It's just that they don't count on [[SpannerInTheWorks the Doctor]] showing up, or Sarah Jane Smith.
* ExposedExtraterrestrials: When they're not in their human suits. Lampshaded with dialogue about it being traditional to hunt naked.
* FaceStealer: Along with the rest of your skin.
* TheFamilyThatSlaysTogether
* FatBastard: 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.
* HannibalLecture: 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."
* HuntingTheMostDangerousGame: The Slitheen family at least, ''really'' like hunting humans.
* KillAndReplace:
-->'''Doctor:''' You're pleading for mercy out of a dead woman's lips.
* OnlyKnownByTheirNickname: 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.
* OverlyLongName: Raxacoricofallapatorius.
* RoguesGalleryTransplant: 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.
* ToiletHumor: The best way to spot a disguised Slitheen? They fart. A lot.
* WeaksauceWeakness: Vinegar. Go figure.

[[folder: Roboforms]]
!! 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.

* BadSanta: A whole brass band of them, complete with [[InstrumentOfMurder weaponized instruments]].
* TheCameo: In "The Pandorica Opens", in their non-Santa forms.
* InstrumentOfMurder: The Roboform wield brass instruments that double as weapons, including a trombone-flamethrower.
* RoboticReveal: Once the mask comes off.
* LesserOfTwoEvils: They're just scavengers who travel alongside the real threat.

[[folder: Sycorax]]
!! Sycorax (Tenth and Eleventh Doctors)
->'''Played by:''' Sean Gilder (2005)

-->''"SYCORAX STRONG. SYCORAX MIGHTY. SYCORAX ROCK!"'' [[note]]As in the modern sense "they rock."[[/note]]

The Sycorax were a superstitious race of warriors. They often wear skeletal masks, with equally skeletal faces underneath.
* TheCameo: In "The End of Time", "The Pandorica Opens", "The God Complex" and "The Magician's Apprentice".
* DuelToTheDeath: 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.
* HeelFaceDoorSlam: 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.
* HistoricalInJoke: The Doctor feeding Shakespeare his own lines. Specifically, it resolves the BrickJoke of the Sycorax set up in [[Recap/DoctorWho2005CSTheChristmasInvasion "The Christmas Invasion"]]; Sycorax is a witch mentioned in ''Theatre/TheTempest'', 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 MeaningfulName 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.
* InsufficientlyAdvancedAlien: 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.
* PlanetSpaceship: 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.
* ProudWarriorRaceGuy: They believe in solving disputes with a DuelToTheDeath.

[[folder: Catkind]]
!!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."

* CatFolk
* CuteKitten: What the babies of this species resemble.
* DominantSpeciesGenes: A Catman and human female husband and wife produces litter of kitten offspring.
* FemaleFelineMaleMutt: 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.
* SaintlyChurch: The Sisterhood run a hospital founded by charity to heal the sick.


[[folder: Clockwork Droids]]
!!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.

* AdmiringTheAbomination: The Tenth Doctor openly admits they're beautiful, before quickly adding that it's not going to stop him breaking them.
* AIIsACrapshoot: 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.
* AlasPoorVillain: When the ''Pompadour'' droids [[DrivenToSuicide 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?
* AwesomeAnachronisticApparel: 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
* BladeBelowTheShoulder
* ClockPunk
* ClockworkCreature: They're literally wind-up droids powered by clockwork, and have a distinct ticking sound when they move.
* CostumePorn: The ''SS Madame de Pompadour'' droids are possibly the best dressed ''Doctor Who'' villains ever.
* CreepyMonotone
* TheCrocIsTicking: A literal ticking sound signals their presence.
* DrivenToSuicide: 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.
* EmergentHuman: The Half Face Man is rapidly approaching this state.
* FaceStealer: In "Deep Breath".
* GoneHorriblyRight: The ''SS Madame de Pompadour'' was nearly wholly repaired, though the crew did not live to see it.
* GorgeousPeriodDress: In 18th century France.
* GrewBeyondTheirProgramming: The Half Face Man gained emotions and even faith due to the sheer amount of human parts he replaced himself with.
* HumanResources / OrganTheft: No one told them they weren't allowed to use human parts.
* HumanityEnsues: 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.
* InsaneTrollLogic: 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.
* JustFollowingOrders: The crew of the ''SS Madame de Pompadour''.
* KillItWithFire: How the Half Face Man hides his actions, destroying everyone it steals from with vast amounts of fire.
* LiteralMinded: 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. EyeScream quickly follows.
* MalevolentMaskedMen: Only when in 18th century France. When stuck in Victorian London, the droids flay their victims and wear their faces.
* MarionetteMotion: Both variants move with stiff, unnatural motions.
* ObliviouslyEvil: 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.
* PaperThinDisguise: 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 MachineMonotone voices, stiff and jerky movements, and the constant ticking, clicking and whirring that follows their every movement.
* PerpetualSmiler: In their masquerade masks.
* RagnarokProofing: 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.
* SlasherSmile: The ''Pompadour'' droids wore creepy, smiling masks.
* ThemeNaming: The ships the clockwork droids work for are named after famous women from history.
* ThreeLawsCompliant: Horribly averted. The Droids follow Rules 2 and 3 (obeying the orders of humans and preserving their own existence, respectively) while ignoring Rule 1.
* WalkingTransplant: Not them, but everyone else is fair game, even a T-Rex isn't safe.
* WetwareCPU: Why Reinette was the target of a kidnapping.
* WouldHurtAChild: 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".

[[folder: Cybus Cybermen]]
!!Cybus Cybermen (Tenth[[note]]and possibly Eleventh; The Cybermen in "The Pandorica Opens" (2010) have a C on their chest, but have technology closer to that of the Mondasian Cybermen[[/note]] and Twelfth 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 [[Recap/DoctorWhoS28E5RiseOfTheCybermen "Rise of the Cybermen"]] in 2006. Get sent into the Void between dimensions, from where they neatly spill over into the regular timeline.
* AssimilationPlot: Every single time they want to "upgrade" everyone.
* TheAssimilator: Coupled with the UnwillingRoboticisation trope.
* BigBadEnsemble: Of the 2006 series, with the Cult of Skaro for the season finale.
* BodyHorror: The Cybering process is... not pleasant. The details aren't given in full, but the general gist is most of the human parts are sliced away, and the remains welded to a metal exoskeleton.
* BroughtToYouByTheLetterS: Due to their more corporate origins.
-->'''Doctor:''' A logo on the front. Lumic's turned them into a brand.
* CatchPhrase: "You will be deleted", or simply "DELETE."
* ChestInsignia: They have a "C" on their chests. Mondasian Cybermen that have copied their template do not share this feature, instead having something more akin to an [[WesternAnimationCodeLyoko inverted XANA symbol.]]
* CreativeSterility: The Doctor describes them with this trope in their debut arc.
-->'''Doctor:''' The Cybermen won't advance. You'll just stay like this forever! A metal Earth with metal men and metal thoughts, lacking the one thing that makes human beings so alive: ''People!''
* CreepyMonotone: All Cybus Cybermen talk in a mechanical, computer-like voice.
* CyberneticsEatYourSoul: [[InvokedTrope Deliberately invoked]] and [[PlayingWithATrope played with]]; the Cybusmen have "emotional inhibitors" because any human who can truly grasp what has happened will GoMadFromTheRevelation and then [[YourHeadAsplode explode]].
* DeadpanSnarker: ''Bizarrely.'' The Cybermen occasionally show a little bit of sass to their enemies. It's very rare, but it happens.
'''Cyberman''': This is obvious.
* TheDreaded: Note the Doctor's reaction when he first sees them. He's utterly terrified, and doesn't even bother fighting them, he just tries to surrender.
* EnemyMine: At first, it was just a case of EvilVSEvil with the Cult of Skaro as the Daleks had no plans of playing together. But eventually once Sec got the Genesis Ark opened, the Cybermen had no choice but to ally with Torchwood and the Doctor to fight them off.
* EvilSoundsDeep: In "The Next Doctor" their voices are much deeper than usual.
** The Japanese dub of their stories gave this trait.
* HumongousMecha: In [[Recap/DoctorWhoS30E14TheNextDoctor "The Next Doctor"]], called a Cyberking.
* ImmuneToBullets: What with being made of metal. They're ''not'' immune to rockets or particle guns, though.
* JetPack: They gained rocket boots much like their parallel counterparts from the 2013 redesigns.
* JoinOrDie: They offer two choices: Upgrade, or refuse. Refusal means you're irrelevant, and irrelevant elements are deleted. However, they might decide someone's not worth upgrading, and kill them anyway.
* KingMook: The Cyber-Controller, who has a slightly modified design and sits on a massive throne.
* MachineMonotone: With the Cybus Cybermen, the Cybermen regain the ability to speak in a constant and unchanging machine-monotone after gradually losing that trait in the eighties, but as DeadpanSnarker shows, they bizarrely lose it too occasionally.
* NewPowersAsThePlotDemands: They get new powers or "upgrades" with each appearance. At first they killed by electrocuting through direct contact, then they can fire lasers, and in their latest appearance they can fly and convert corpses into Cybermen using "cyber pollen".
* ObliviouslyEvil: They genuinely think that UnwillingRoboticization is a favor for humanity.
* PsychoElectro: Their original method of killing was to electrocute victims.
* RoboSpeak: They have a tendency to use more tehcnical terms when speaking.
* StompyMooks: They constantly march in formation while making as much ominous noise as possible... so the Doctor is very surprised when they manage to sneak up on him in "The Next Doctor". "D'you have your legs on silent?"
* UniformityException: Cyber-Leaders have black handlebars, compared to the rank-n-file's grey. Likewise, the lead Cyberman in "The Next Doctor" has a visible brain, like the Cyber-Controller ''and'' a black face plate.
* UnwillingRoboticisation
* UtopiaJustifiesTheMeans: Their idea of a utopia, at least.
* VillainTeamUp: They teamed up with both of their parallel counterpart Cybermen.
* WasOnceAMan
* WellIntentionedExtremist: The original purpose of the Mondasian Cybermen was to survive at the cost of their humanity, which they genuinely believe to be the right thing. The Cybus Cybermen are basically the same, except the factors that influenced the motivation are much more selfish.
* YourHeadAsplode: They make a habit of this.

[[folder: Ood]]
!!Ood (Tenth and Eleventh Doctors)
->'''Voiced by:''' Silas Carson (2006–10, 2012)

-->''"The circle must be broken, so that we can sing."''

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.
* BizarreAlienBiology: 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.
* DarkIsNotEvil: 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 DemonicPossession.
* HappinessInSlavery: Via lobotomy.
* HiveMind: Governed by a large living brain situated on their planet called the "Ood Brain", without it the Ood would die.
* PerfectPacifistPeople: They are naturally a peaceful race, which is why the humans chose to turn them into a SlaveRace.
* RedEyesTakeWarning: When they were [[Recap/DoctorWhoS28E8TheImpossiblePlanet controlled by the Beast]]. And later again when the [[Recap/DoctorWhoS30E3PlanetOfTheOod Ood Brain managed to reach out and make the Ood take revenge against their human captors]].
* ShoutOut: 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 [[TabletopGame/DungeonsAndDragons 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.
* SlaveRace
* WeakWilled: In addition to their status as SlaveRace, 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.

-->''"FO! SHO! RO! KO! BLO!"''

The law enforcement arm of the Shadow Proclamation, Judoons look like bipedal rhinos in BadassBiker gear. They are extremely fond of rules and regulations, as seen in ''Series/TheSarahJaneAdventures'', and a bit thick.
* BadassBiker: Just the outfits, not the rebellion.
* ByTheBookCop: Played with; although the Judoon strictly obey the letter of the law, their "book" allows for a lot of CowboyCop or even KnightTemplar behavior on their part.
* DisproportionateRetribution: 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.
* TheDragon: As a whole, for the Shadow Proclamation.
* LawfulStupid: 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.

[[folder: Weeping Angels]]
!!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!"''
-->-- '''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 SuperSpeed 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.
* AbstractEater: They feed on time energy, sending people back in time and consume all the years they would have lived in the present.
* AlwaysChaoticEvil: 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 ''[[Recap/DoctorWhoS33E5TheAngelsTakeManhattan The Angels Take Manhattan]]'', who sent Amy back in time to the same point as Rory when it could've easily done otherwise.
* AmbiguousGender: While this is rather appropriate for an angelic being, it only serves to increase the UncannyValley for these.
* AndIMustScream: 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.
* AstonishinglyAppropriateAppearance: At first glance, they appear to be statues that would be seen in a cemetery. Look away, and it's your funeral.
* BizarreAlienBiology: Creatures of the abstract. They turn to stone when anyone is looking. Ultimate defense mechanism.
* BreakoutVillain: 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.
* CreepyChangingPainting: 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.
* EldritchAbomination: 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.
* EnfanteTerrible: 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 ''[[ParanoiaFuel 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.
* EverythingTryingToKillYou: 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'''''.
* EvilLaugh: 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.
* FangsAreEvil: They show off fangs as they rush in to attack.
* FauxAffablyEvil: 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.
* FemmeFatalons: 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.
* FateWorseThanDeath: 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.
* ForTheEvulz: The reason they give for making Amy Pond count down to her own death is "for fun, sir".
* TheFourthWallWillNotProtectYou: 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".
* GenericDoomsdayVillain: They are a case of this [[TropesAreNotBad trope working their favor]]. The fact that on top the sheer NightmareFuel 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.
* HealingFactor: 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.
* HoistByHisOwnPetard:
** 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.
* HumanoidAbomination: Their "quantum locked forms" look like human statues, until you look away and the abomination comes forth.
* ImplacableMan: 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.
* KickTheDog: Angels will taunt and torment anyone and anything that looks delectable. In the case of the babies, it's PokeThePoodle, since they can't do as much harm.
* LightFlickerTeleportation: 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.
* LightIsNotGood: 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''!
* LivingStatue: 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.
* MadeOfIron: 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 HealingFactor. 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".
* NeckSnap: 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.
* NewPowersAsThePlotDemands: 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 OffscreenTeleportation 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.
* NightmareFace: They look very UncannyValley 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.
%%* NightmareFuelStationAttendant
* NobodyHereButUsStatues: 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.
* OffscreenTeleportation: Their explicit super-power, although it's more of a restriction, as they ''cannot'' move while someone is looking at them.
* OnlyKnownByTheirNickname: 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.
* OurGargoylesRock: They're not gargoyles but their statue forms appear to be them in the right location.
* RealityWarper: A minor example, there are limitations to what they can do, but they can defy several laws of physics. Father Octavian calls them "god" after witnessing what they are capable of.
* ScareChord: Their [[http://www.youtube.com/watch?v=V5QM-Csxqu8 Leitmotif]].
* SlasherSmile: If an Angel knows victory is at hand and its victims have no chance of escape, it flashes a horribly malicious grin at them.
* StaringContest: 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.
* StepIntoTheBlindingFight: 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.
* StupidEvil: 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.
* SuperSpeed: They need only the time it takes to blink to dart forward and slay their victim.
* TakenForGranite: 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 ParanoiaFuel last terrifying minute and a half of "Blink" and outright confirmed in their third appearance.
* TheVoiceless: 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.
* TimeAbyss: They're as old as the Universe, or very nearly.

!!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."
* ChildrenAreInnocent: Averted. The Toclafane display childish personalities and speech patterns, but they are psychotic, sadistic and callous, even when fighting their own ancestors.
* CyberneticsEatYourSoul: They mutilated themselves into their current state and are willing to kill off their ancestors.
* {{Cyborg}}: They are human heads encased inside robotic spheres.
* ForTheEvulz:
-->'''Martha:''' But why? Why come all this way just to cause all this death and destruction?\\
'''Toclafane:''' Because it's FUN!
* GrandfatherParadox: 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.
* HumanAllAlong: The Toclafane turn out to be the humans from the far future in "Utopia".
* HumansAreTheRealMonsters: 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.
* MadnessMantra:
-->'''The Toclafane''': We shall fly and blaze and slice! We shall fly and blaze and slice!
* SameStoryDifferentNames: 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.

* BabyTalk: A justified example, as in their debut they ''were'' babies.
%%* BlackBeadEyes
* BlobMonster: In the words of Matron Cofelia "the fat just 'walks away'."
* ChildrenAreInnocent: 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.
* RidiculouslyCuteCritter: Baby Adipose look like plush toys.
* PoweredByAForsakenChild: 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 [[http://doctorwho.tumblr.com/ official Doctor Who tumblr blog]], mostly due to how incredibly cute and huggable they are.
* TheWormThatWalks:
** 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.
* FishPeople: Rather large fish people at that.
* TheUnintelligible: Communicate by bubbling the odd containers of green liquid in their mouths.

[[folder: Vashta Nerada]]
!!Vashta Nerada (Tenth Doctor)
--> ''"These are our forests. They are our meat."''

Also known as "[[LivingShadow 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.
* BrokenRecord: 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?
* TheCrocIsTicking: You can tell that a swarm of Vashta Nerada has eaten someone when the microphone starts acting like a BrokenRecord and repeats the same phrase over and over.
* DarknessEqualsDeath: If you enter a shadow that the Vashta Nerada occupies, you will be devoured.
* DarkIsEvil: {{Living Shadow}}s that devour humans and [[StrippedToTheBone strip them to the bone]].
* ItCanThink: 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 InstantDeathRadius, 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.''
* LivingShadow: 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.
* PrimalFear: The species is implied to be the reason that many species have a natural fear of the dark.
* StrippedToTheBone: When they devour humans and a chicken leg, all they leave are bare bones.
* TheSwarm: They're thousands of microscopic carnivores working in unison.
* ZombieGait: It's not like space suits are designed to be piloted by swarms of thousands of miniscule creatures that ate the previous occupant.[[/folder]]

[[folder:The Atraxi]]
!! 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 destroy an entire planet to eliminate their quarry.
* CanonImmigrant: The planet Atraxi3 is first mentioned in the Eighth Doctor Adventures novel "Vampire Science."
* DoNotAdjustYourSet: The Atraxi are capable of hijacking every transmission on every TV and radio channel on Earth in their search for the escaped Prisoner Zero.
* FacelessEye: The Atraxi; giant flying eyeballs surrounded by a crystal snowflake.
* GiantEyeOfDoom:
* KillItWithFire: How the Atraxi intend to deal with Prisoner Zero and the human residence.
* OculoThorax: The Atraxi are a Giant Eye of Doom that can fly through outer space.
* StarfishAliens: The Atraxi, putting the "alien" in "alien police" with their big eyeballs and crystalline web ships.


[[folder:The Silence]]
!! The Silent Priests (Eleventh Doctor)
-> '''Played by:''' Marnix Van Den Broeke (2011)\\
'''Voiced by:''' Barnaby Edwards (2011)

--> ''"Silence will fall."''

The faces (creepy, creepy faces) of [[ReligionOfEvil a religious order called "the Order of the Silence"]], the {{Big Bad}}s 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.
* AlienInvasion: The invasion is long over (at least in an alternate reality anyway). They've been controlling the planet for the last 10,000 years.
* AmnesiaDanger: They cause it due to a function in their biology. As soon as you look away, you forget they're nearby.
* BadassBoast: 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.
* BackForTheFinale: They appeared in the Eleventh Doctor's last episode, after not appearing for over two years.
* BadassInANiceSuit: They wear nightmarish versions of stylish black and white business suits.
* BigBad: [[RenegadeSplinterFaction 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.
* TheBlank: They have to prominent eyes, but that's it. They otherwise lack other familiar facial features like a nose, mouth, or ears.
* BreakoutVillain: Along with the Weeping Angels, they are the revival series most popular villains.
* CatchPhrase: '''Silence will fall''', almost serves as the ArcWords.
* CeilingCling: They sleep hanging upside down. ''In packs.''
* ChurchMilitant:
** Part of the [[ReligionOfEvil 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 RenegadeSplinterFaction, attempting to alter history to prevent him ever reaching Trenzalore.
* CreepyGood: "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 RenegadeSplinterFaction. They just look scary.
* DressCodedForYourConvenience: Evil Silences wear ties, Good Silence wear collars.
* EvilSoundsDeep: Talk in creepy, raspy voices.
* FourFingeredHands: They have large four spatula fingers, with one large one used to [[ShockAndAwe discharge electricity]].
* GambitRoulette: 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 ClapYourHandsIfYouBelieve magic from his TouchedByVorlons 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 TrickedOutTime gambit to survive getting shot.
* GlassCannon: They can easily disintegrate people, break through thick glass and heavy doors, but they can be killed fairly easily through conventional means.
* TheGreys: According to WordOfGod, the idea is that stories of alien abduction by TheGreys, among other things, represent half-retained memories of the Silence when on occasion people don't quite forget everything.
* GoodShepherd: 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.
* HiddenAgendaVillain: Despite being around since series 5, it's only in the final episode of series 7 the [[RenegadeSplinterFaction 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.
* HoistByHisOwnPetard: 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.
* KickTheDog: 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 [[MeaningfulName Joy.]]
* LaserGuidedAmnesia: Their power is to make people forget the moments with them.
* LeaningOnTheFourthWall: 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.
* TheMenInBlack: According to WordOfGod, one of the inspirations for them. Hence the black suits and memory damage.
* MundaneUtility: 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.
* NiceJobBreakingItHero: 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.
* NightmareFace
-->'''Amy:''' You're ugly. Has anyone ever told you that?
* NoMouth: Although a hole reminiscent of ''TheScream'', where their mouth should be, forms when they discharge electricity.
* TheNoseless: They appear to have nostrils, but no definable nose.
* OhCrap: Upon realizing that the Doctor just turned their own tactics against them, and now all humans are going to start killing them on sight.
* OmnicidalManiac: They're the ones responsible for ''destroying the TARDIS and the universe on [[Recap/DoctorWhoS31E12ThePandoricaOpens June 26, 2010]]''. '''[[ArcWords Silence will fall]]'''. Let's put this into perspective. If you make the ''Daleks'' try to prevent your victory, you've '''earned''' the title.
* OnlyKnownByTheirNickname: "The Silence" is the name of their ReligionOfEvil, 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.
* OutsideContextProblem: The Doctor hadn't even heard of these things before they came after him (at least as far as he can remember).
* ParanoiaFuel: 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.
* PsychologicalHorror: 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.
* ReligionOfEvil: 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.
* RenegadeSplinterFaction: 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 WellIntentionedExtremist) Silence.
* ShockAndAwe: 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.
* ShoutOut: According to WordOfGod, they were visually inspired by the famous painting ''TheScream''.
* TheSpook: 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.
* SquishyWizard: 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.
%%* SssssnakeTalk
* StaringContest: Keep eye contact with them at all times, otherwise you forget them and they kill you.
* SuperNotDrowningSkills: They seem perfectly fine when immersed in liquid for long periods in "The Wedding of River Song".
* WellIntentionedExtremist: 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.
* WhamLine: "You should kill us all on sight." Not when ''they'' say it, but when it is [[HoistByHisOwnPetard used against them]]!

[[folder: Gangers]]
!!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'').
* AndIMustScream: The partially melted down Gangers; rotting but fully alive and conscious.
* BodyHorror: The rotting Gangers — partially melted but still conscious. There are eyes in one of the walls, made of more living Flesh.
* ChekhovsGun: In "A Good Man Goes to War", a Ganger is used as a duplicate for Melody.
* ClonesArePeopleToo: Heavily explored and established, especially with the Gangers of Jennifer and Jimmy.
* CloningBlues: 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.
* ContinuityNod: In "The Almost People", one decommisioned Ganger resembles the villainess Cassandra from [[Recap/DoctorWhoS27E2TheEndOfTheWorld "The End of the World"]] and [[Recap/DoctorWhoS28E1NewEarth "New Earth"]]. The Gangers also seem to be "forced-growth clones", like Chip, Cassandra's servant.
* DeadlyEuphemism: Gangers, being considered implements, are not killed but "decommissioned." {{Justified|Trope}} in that originally they were avatars of people, not sentient beings in and of themselves.
* FinishingEachOthersSentences: This happens with the Doctor and his Ganger; same wavelength!
* GlamourFailure: The Gangers occasionally shift back to their gooey, half-formed selves for a brief moment.
* GoMadFromTheRevelation: Ganger!Jennifer completely loses it thanks to all her memories of being 'decommissioned'.
* HiveMind: 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.
* InSeriesNickname: The TARDIS team seem to have dubbed them "Flesh Avatars".
* MeaningfulName: "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).
* NightmareFace: An incomplete Ganger has a gooey white face.
* ReplacementGoldfish: Two of the original humans are killed and their Gangers resume their lives for them.
%%* RubberMan: The Gangers.
%%* SpotTheImposter
%%* TomatoInTheMirror
* WhatMeasureIsANonHuman: 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.

[[folder: Tivolians]]
!!Tivolians (Eleventh and Twelfth Doctors)
-> '''Played by:''' Creator/DavidWalliams (Gibbis) (2011); Paul Kaye (Prentis) (2015)

-->''"If you occupied us, you'd be home by now."''

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.
* LesCollaborateurs: 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.
* DirtyCoward: They straddle the line between these this and LovableCoward. 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.
* GettingCrapPastTheRadar: In "Before the Flood", Prentis' love of being oppressed seems sexual in nature. The Doctor is not amused.
%%* HappinessInSlavery
%%* MoleMen
* PlanetOfHats: An extreme example even for Doctor Who. An entire race of people who love being oppressed by invaders.
* RubberForeheadAliens: Tivolians look like humans with rodent-like features.
* StockholmSyndrome: One interpretation for why the Tivolians enjoy being oppressed.
* TheQuisling: An entire planet who welcome any and all alien invaders. Their planetary anthem is "Glory to ".

[[folder:Whisper Men]]
!!Whisper Men (Eleventh Doctor)
-> '''Played by:''' Paul Kasey

-->''"The trap is set. The Doctor's friends. Will travel where the Doctor ends."''

Mysterious 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.
* BadassInANiceSuit: Dress in Victorian era garbs.
* TheBlank: Lack facial features except for [[NightmareFace 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 Face}}s and [[BadassInANiceSuit 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.
* IntangibleMan: 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.
* NightmareFace: [[TheBlank Faceless horrors]], save for one large snarling mouth.
* RhymesOnADime: Always speak in rhymes.


[[folder: The Boneless]]
!!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!"''
-->-- '''Twelfth Doctor'''

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.
* AmbiguouslyEvil: 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.
* EldritchAbomination: Creatures that come from a 2-D plane of existence.
* FlatWorld: Their universe is two-dimensional, so they're from a very literal version of this trope.
* ForTheEvulz: As enigmatic as they are, it is made clear that they are gleefully aware of the harm they're causing.
* HiddenAgendaVillain: Their motives are left deliberately unclear and many hypotheses are brought up during the episode; perhaps they're here to contact us, [[KillAllHumans kill us all]], dissect or study us and [[ObliviouslyEvil don't even know that we require 3 dimensions to survive]].
* HumanoidAbomination: Eventually they take the form of those they've killed when they finally understand 3 dimensions.
* KnownOnlyByTheirNickname: 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.
* PaperPeople: Comes with being 2-D lifeforms.
* StarfishAliens: Beings from a 2-D dimension that are attacking Earth.
* StarfishLanguage: 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.
* StealthPun: They're two-dimensional in more ways than one.
* TheyWouldCutYouUp: Rare alien-on-human example. They turn humans into 2-D and dissect them to understand their bodies so they can become 3D.
* ZombieGait: 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.

[[folder: Dream Crabs]]
!!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."''
-->-- '''Twelfth Doctor'''

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.
* BigCreepyCrawlies: They're colloquially called "crabs", and have a spider-like movement, but actually resemble giant, misshapen hands.
* DreamWithinADream: They create layer upon layer of dreams, so that the victim can never discern dream from reality.
* EnemyWithin: 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 [[Film/{{Alien}} the Facehuggers]].
* NoBodyLeftBehind: They crumble to dust once they die. The Doctor explains that this is a "carnivore's hazard, food has teeth too."
* SchrodingersButterfly: 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 DreamWithinADream certainly make this much harder.
* StarfishAliens: 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.
* SweepingAshes: 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.

[[folder:Cloister Wraiths]]
!!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.
* AndIMustScream: Their faces are frozen in a perpetual rictus of horror.
* CobwebOfDisuse: What happens to their prey. The Doctor and Clara find Daleks, Cybermen and Weeping Angels that have been caught by them.
* FateWorseThanDeath: Becoming one of these things doesn't look very pleasant.
* NonHumanUndead: They're long dead-Time Lords, and appear almost akin to ghosts.
* ThresholdGuardian: The Cloister Wraiths guard the Matrix. Anybody caught in there eventually becomes a part of the firewall.
* VirtualGhost: They appear to be at least partially hologramatic, and they don't look happy about it.


[[folder:Shoal of the Winter Harmony]]
!!Shoal of the Winter Harmony (Twelfth Doctor)


* AscendedExtra: They go from being relatively minor villains in ''[[DoctorWho2015CSTheHusbandsOfRiverSong The Husbands of River Song]]'' to the BigBad of ''[[Recap/DoctorWho2016CSTheReturnOfDoctorMysterio The Return of Doctor Mysterio]]''.
* BaldOfEvil: Scratch and the rest of the Shoal of the Winter Harmony members were like this, their successors in the ''[[Recap/DoctorWho2016CSTheReturnOfDoctorMysterio The Return of Doctor Mysterio]]'' avert this.
* BigBad: They serves as the main threat of the [[Recap/DoctorWho2016CSTheReturnOfDoctorMysterio 2016 Christmas special]].
* BrainInAJar: They literally appear as brains in jars before they are transplanted to a new host.
* BrainTransplant: They infiltrate planets by transplanting their brains into that of civilians.
* EvilPlan
* {{Expy}}: They are not unlike the Slitheen as aliens who pretend to be humans by wearing the skins of their victims.
* GoodScarsEvilScars: They can be spotted as having a telltale diagonal scar running across their faces, which can actually split open.
* GrandTheftMe: The modus operandi of this alien menace, who swap themselves into human hosts while removing their brains.
* HyperspaceMallet: Harmony Shoal members are able to store things in their heads. ''Literally''. They just split open their head and pull the item out.
* KillAndReplace: They surgically remove the brains of their victims, before one of their species is put inside the body as a vessel.
* ManipulativeBastard: Their EvilPlan is so brilliant that even the Doctor is impressed, before complaining how his side never comes up with ideas like this.
* RedRightHand: 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.

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. [[spoiler: [[Recap/DoctorWhoS36E12TheDoctorFalls As it turns out, all of it did.]] [[ThePowerOfLove Including her love for Bill.]]]]
