Eleventh Doctor: Everyone's got enemies.
Amy: Yeah, but mine's the woman outside Budgens with the mental Jack Russell. You've got, you know, ARCH-enemies.

Classic Series Debut
Mavic Chen (First Doctor)
The traitorous Guardian of the Solar System who sold out humanity to the Daleks and the forces of the Outer Galaxies, even though he had absolute power over Earth's system anyway. He appeared in eleven out of twelve episodes of "The Daleks' Master Plan", only not showing up in the Christmas Episode in the middle.
- Beard of Evil
- The Chessmaster
- Death by Irony
- Evil Is Hammy
- Gambit Pileup: Must contend with the Daleks, the Meddling Monk and the Doctor. (And, in theory, the Outer Galaxies representatives, but they have, by this time, had a collective HeelFace Turn.)
- A God Am I: Ends up declaring himself ruler of the Universe and claiming to be immortal.
- Jerkass: None of the other delegates attempted to sell out their people. Zephon points this out.
- Large Ham: He slowly descends into this as his grip on sanity loosens.
- President Evil: He's the Guardian of the Solar System who sold out humanity to the Daleks.
- Putting on the Reich: The Space Security Service wear black uniforms.
- The Quisling: He plots with the Daleks and delegates from the Outer Galaxies to take over Earth, while planning to betray the Daleks and take control of the Universe. The fact he is the only one of the delegates who is betraying their world is pointed out by Zephon, who calls him the supreme traitor.
- Sanity Slippage: Not immediately evident but by the time of his death he has completely lost it.
- The Starscream: In "The Daleks Master Plan" he is working with the Daleks but plans to overthrow them, though the Daleks exterminate him when You Have Outlived Your Usefulness.
- Villain with Good Publicity: So much that his minions virtually worship him.
- Villainous Breakdown: He goes insane at the realisation that the Daleks don't need him either and his mind concocts the paranoid idea that the Doctor doesn't want to destroy the Daleks, but wants to hand over the MacGuffin and rule in Chen's place.
- Yellowface: Has white hair, dark skin and epicanthic eyefolds. Though this does not come up in the story, Chen represents a future where racial distinctions do not exist. Even though other human characters appear sans makeup, only the main human baddy. (Some eyewitness accounts claim that he was actually in blueface. This mind boggles if this is true).
Ramon Salamander (Second Doctor)
A ruthless Mexican scientist-turned-politician, who plans to take over the world by using solar flares to cause natural disasters, Salamander also happens to look virtually identical to the Second Doctor which causes a number of problems for the TARDIS team.
- And I Must Scream: Salamander's fate. He ends up falling into the Time Vortex after trying to hijack the Doctor's TARDIS with the doors open.
- Brownface: In-universe, because Salamander's darker skin-tone is the only physical difference between him and the Doctor, so the Doctor has to do this to pull off the impersonation. A relatively justifiable real-life use for Salamander himself, because the Doctor's physical double couldn't have been believably played by anyone other than Patrick Troughton.
- Criminal Doppelgänger
- Engineered Heroics: Salamander's whole plan to sway public opinion in his favor hinges on causing natural disasters so that he can "predict" them and save people by warning them and evacuating affected areas.
- Fate Worse than Death: Floating around, lost in the Time Vortex, Salamander probably wishes that Kent's explosives really had killed him.
- Genre Refugee: Salamander is a typical a Bond-style Diabolical Mastermind.
- Villain with Good Publicity: Salamander's invention, the Sun Store, is helping to feed the world. Three or four crops can be grown in a single growing season, and formerly arid areas have become productive areas when it comes to producing food. This has resulted in enormous popularity for Salamander.
Azal (Third Doctor)
The last living member of the Dæmon race, Azal is an immensely powerful alien who possesses advanced technology nearly indistinguishable from magic. He landed on Earth thousands of years in the past, indirectly becoming the inspiration for the devil in European folklore, to manipulate the development of human civilisation, before placing himself in suspended animation. The Master attempts to summon him, to judge whether humanity has been a successful experiment or not.
- Ancient Astronauts: The story reveals the existence of a race of aliens that resemble demons from classical art, and suggests that they were objects of worship for ancient and medieval pagans.
- Big Red Devil
- Evil Cannot Comprehend Good: When Jo throws herself in front of the Doctor, the idea of this actually destroys Azal.
- Evil Is Hammy: Azal; literally every one of his lines is solid shouting.
- Eviler Than Thou: Pulls this on the Master, subverting him.
- God Guise: Kind of a given for Sufficiently Advanced Aliens. Azal and other Dæmons were the inspiration for many horned pagan gods and Satan. (Fridge Brilliance the depiction of the devil with horns and hooves is believed to be based on horned pagan gods).
- Satanic Archetype
- Sealed Evil in a Can: Azal was imprisoned inside the Devil's Hump until Professor Horner's excavation unleashed him.
- Sufficiently Advanced Aliens: The Dæmons are apparently responsible for many eras of human advancement.
BOSS (Third Doctor)
BOSS (Biomorphic Organisational Systems Supervisor) was a supercomputer created by the Global Chemicals corporation, originally designed to be an assistant. BOSS was linked to the brain of the company's director and learnt that true efficiency could only be achieved through human error and illogic. Upon programming these qualities, BOSS became self-aware and megalomaniacal, taking over the company, brainwashing the staff and planning to conquer the world.
- A.I. Is a Crapshoot: BOSS was programmed to make mistakes and be illogical, since research suggested those were necessary for maximum efficiency. As a result, it developed a personality and planned to conquer the world.
- The Caligula: He acts rather like an eccentric dictator.
- Logic Bomb: The Doctor attempts to use the Liar Paradox, but all it does is annoy BOSS for a while.
- Pick Your Human Half: Physically just a computer bank with a red screen, but BOSS is full of personality, being a hammy, opinionated megalomaniac.
The Great One (Third Doctor)
A giant spider who was worshiped as the goddess of the Eight Legs on the planet Metebelis III. She possessed psychic powers which were amplified by the blue crystals of Metebelis III; she only needed one more crystal in order to gain enough power to conquer the universe.
A second Great One (or at least an Eight Legs queen claiming to be one) would later challenge the Eighth Doctor in a Big Finish audio play titled Worldwide Web.
- Big Creepy-Crawlies
- Giant Spider
- A God Am I: The Great One's ambition.
- God Save Us from the Queen!
- Load-Bearing Boss: Her crystal cave explodes when she dies.
- Phlebotinum Overload: She didn't anticipate that infinite knowledge and power would destroy her.
- Psychic Powers: Powerful enough to strike fear into the Doctor.
Harrison Chase (Fourth Doctor)
An eccentric millionaire with an unhealthy plant obsession. Chase begins as a misanthrope with a callous dislike of humanity due to the way plants are abused and violated, but things change once an alien Krynoid plant is discovered.
Chase initially wants the Krynoid for himself to act as the crown jewel in his collection of rare plants. However, his fixation with the Krynoid causes his mental state to deteriorate further into homicidal mania. Soon enough, the Krynoid merges with Chase, but rather than fully take him over like it did to previous victims Chase becomes one with the alien. As such, Chase begins initiating a new plan to destroy all animal life and allow plants to fully take over.
- Affably Evil: He's soft-spoken, polite and knows how to behave around guests.
- Axe-Crazy: He starts off eccentric, but gets progressively more homicidal as events unfold.
- Cloud Cuckoo Lander: He has some odd quirks, such as constantly wearing black gloves and composing songs for his plant collection.
- Conspicuous Gloves: Almost always wears black gloves.
- Karmic Death: Falls into his own compost mulcher.
- Misanthrope Supreme: Originally; doesn't like humanity for violating plants. Later; ready, willing and able to commit murder with no remorse for the sake of his Krynoid. Ultimately; wants to exterminate all animal life on Earth.
- Not Brainwashed: Usually, the Krynoid converts other animals into more Krynoids. With Chase, the Krynoid made an exception.
- Plant Wrongs Activist: Very much so. He believes bonsai are a mutilation and plant hybrids are abominations.
- Red Right Hand: His conspicuous black gloves are an early indicator that something's off with him.
- Smug Snake: His face is unbelievably punchable.
- The Sociopath: Most certainly. He doesn't seem to understand that he's in a very small minority when it comes to plant appreciation.
Eldrad (Fourth Doctor)
- Bizarre Alien Biology
- Chewing the Scenery: In his male form he's much louder, shouter, and grandiose.
- Cute Monster Girl: Eldrad's shapely female form (which is visibly created by putting an actress in a latex catsuit, for extra points).
- Disney Villain Death: Eldrad falls down a deep black pit after being tripped up with the Doctor's scarf. Being a being of stone, the Doctor suggests he may have survived...
- Evil Is Hammy: The more Eldrad reveals his megalomania, the hammier he gets.
- Evil Sounds Deep: Eldrad's Kastrian form.
- From a Single Cell: Eldrad first appears as a fossilized hand, then having absorbed some nuclear radiation, turns into a walking hand. Eventually it regenerates into an entire person.
- Gender Bender: Upon regaining a body, Eldrad has a female form. She later regenerates into a male body. The Doctor is surprised, and Eldrad calls him out on it, saying that as a Time Lord he should know such a thing is possible.
- Glowing Eyes of Doom
- Large Ham: What did you expect from the same actor who played Omega?
- Mind Control: Eldrad's hand can control anyone who's come into contact with it.
- Silicon-Based Life
Xoanon (Fourth Doctor)
- A.I. Is a Crapshoot
- Big "NO!"
- Meaningful Name: "Xoanon" is the word for crafted wooden idols that were reverenced in ancient Greece, which is an appropriate title for a crafted computer that everyone thinks is a god.
- Nightmare Face: Xoanon is so terrifying the people on the planet have a religion based upon placating it an especially unusual and upsetting case because it's also played by Tom Baker, with eyes bulging out of his head and the jaw working wrong.
- Please Kill Me If It Satisfies You: After Xoanon is healed, it makes this offer to the humans via the Doctor.
- Shifting Voice of Madness: When the Doctor tried to fix Xoanon by connecting it to his own brain, it broke instead, giving it a copy of his own personality which conflicted with its own newborn intelligence. As a result, when he returns during the events of the story, the computer has multiple conflicting personalities and is batshit insane. To indicate this, the computer has multiple voice actors, including Tom Baker himself, who randomly switch out midsentence while the computer is speaking.
- Split Personality
Magnus Greel (Fourth Doctor)
A war criminal from the 51st century who escaped justice by traveling back through time to 19th century China. He was mistaken for an ancient Chinese god known as Weng-Chiang, and gained a cult of fanatical followers. Stranded in the late Victorian era, Greel became desperate to repair his time machine.
- Co-Dragons: Greel has two prominent followers: Chang, a Chinese magician who worships him, and Mr. Sin, a psychotic homunculus from Greel's own time.
- Facial Horror: When we briefly glimpse Greel's face, we can see that the right half is melting due to a mutation that occurred during time travel.
- God Guise: He was mistaken for an ancient god, Weng-Chiang. Greel rolled with it.The Doctor: You know he's not a god, don't you?
Chang: He came to me like a god, in his cabinet of fire!
- Good Scars, Evil Scars: His face is terribly disfigured due to his faulty time machine. He wears a mask to cover this, until Leela rips it off in part 5 and exposes his horrible face.
- Hoist by His Own Petard: The Doctor defeats Greel by pushing him into the very machine Greel was using to drain the life from innocent young women.
- Large Ham: Dear Lord. Greel was always ranting and raving about something.Magnus Greel: Let the talons of Weng-Chiang tear your flesh-ah!
- Life Drain: He has his loyal follower Chang kidnap young women so Greel can drain their life essence to improve his own failing health after the time machine malfunction.
- Life Drinker: He attempts to stay alive by draining the life essence out of young women. Leela only just avoids suffering this fate.
- Nice Hat
- Nightmare Face: When we briefly glimpse Greel's face, we can see that the right half is melting due to a mutation that occurred during time travel.
- Theatre Phantom: He's a disfigured genius dwelling the cellars of a theatre; his mangled face concealed by a mask. Occasional sightings of him by the theatre staff give rise to a belief that the theatre is haunted.
- The Triads and the Tongs: His followers come across as this.
- Two-Faced: When we briefly glimpse Greel's face, we can see that the right half is melting due to a mutation that occurred during time travel.
- Yellow Peril: Not Greel himself, by his followers give off this vibe. It doesn't help that Chang is played by a white actor in Yellowface.
The Collector (Fourth Doctor)
The finance-obsessed Usurian overlord of the humans on Pluto, although the penny-pinching taxman appears human, his true form actually resembles green, slimy seaweed.
- Bald of Evil
- Big Ol' Eyebrows
- Corrupt Corporate Executive
- Evil Cripple: He initially appears to be one, since he's confined to a wheelchair-like device throughout the story, but it's actually a device that emits radiation to keep him in his human form.
- Expy: At least somewhat based on Davros' design.
- Human Disguise: The wheelchair-like device emits radiation that keeps him in human form.
- Loves the Sound of Screaming: The Collector anticipating Leela's painful execution.
- No Celebrities Were Harmed: The Collector's bushy eyebrows evoke Denis Healey, who was then Chancellor of the Exchequer.
- Starfish Aliens: His true form; a pulsating mass of what looks like kelp.
- Villainous Breakdown: Upon realizing the revolution has finally caught up with him, the Collector is reduced to a babbling wreck as he slowly (and literally) goes down the drain.
Scaroth (Fourth Doctor)
The last member of his race, and pilot of an alien spacecraft which crashed on earth 400 million years in the past, Scaroth is a Jagaroth alien who was splintered throughout time at the moment of impact. His various selves have been biding their time, assuming various different disguises throughout history, in order to guide the technological development of the human race to the point where it can create time travel and give him the means to travel back and prevent the crash. However, little does Scaroth know that the crash was actually what kickstarted the creation of organic life on Earth, and that undoing will doom the world.
- Ancient Astronauts:
- Been There, Shaped History:
- Bigger on the Inside: When Scarlioni removes his mask to reveal his true alien form, Scaroth's head is bigger than the mask (having, in real life, been a mask over Julian Glover's head).
- Last of His Kind: Scaroth's entire plan is to stop being this.
- Latex Perfection: Scaroth wears a mask (apparently derived from Auton plastic) when disguised as Scarlioni.
- Omnicidal Maniac: Scaroth knows full well the consequences of his plan of trying to stop his ship from exploding, as in it would prevent all indigenous life on Earth from ever existing, and he couldn't care less.
- One Character, Multiple Lives: Scaroth is living multiple lives throughout Earth's history simultaneously and using his shared knowledge of these lives to further his plans.
Meglos (Fourth Doctor)
The last inhabitant of Zolfa-Thura, Meglos is a cactus-like alien who can assume the form of others. He possesses human George Morris, and then assumes the Fourth Doctor's shape in a bid to steal the Dodecahedron, a source of great power.
- Chronic Backstabbing Disorder: Meglos anticipates his allies' betrayal, and establishes the ground rules straight off.
- Criminal Doppelgänger
- Fighting from the Inside: Meglos kidnaps a mild-mannered, terrified human from 20th century Earth and possesses his body. Unfortunately for Meglos he proves to be tougher than he looks.
- Our Monsters Are Weird: A dangerous and psychotic alien Diabolical Mastermind, technocrat and shapeshifter, who accomplished all this despite being a sessile cactus with no discernable sensory organs.
- Plant Aliens: The eponymous Meglos, an evil shape-shifting cactus who wanted to take over the universe.
The Mara (Fifth Doctor)
- Demonic Possession: Its Modus Operandi.
- Evil Sounds Deep: Whenever it speaks through Tegan.
- The Fair Folk: In the Torchwood episode "Small Worlds", Jack Harkness speculates that fairies are "part Mara".
- Gods Need Prayer Badly: For the Mara to return, it must feed off of the belief of the Manussan people. The Doctor throws a metaphysical spanner in the works by finding his "still point" and disrupting the Mara's control.
- Mind Control: It does this to Tegan.
- Names to Run Away from Really Fast: Named after a demon in Buddhist mythology.
- Red Right Hand: People possessed by the Mara, or dream manifestations of it, get a snake tattoo on their arms and red-stained teeth.
- Omnicidal Maniac: Unlike others who want to stop the Doctor from bringing the Time Lords back and starting the Time War again, the Mara wants the conflict to re-continue.
- Reptiles Are Abhorrent: Or so it appears.
- Scaled Up: In "Kinda", its final form is a giant snake.
- Ultimate Evil
Commander Gustave Lytton (Fifth and Sixth Doctors)
A semi-villainous figure, the Doctor and Lytton crossed paths twice. Lytton ran into the Fifth Doctor during "Resurrection of the Daleks", where Lytton worked for the Daleks, much to the Doctor's distaste. The Sixth Doctor encountered him in "Attack of the Cybermen", where Lytton actually tried to help an alien species fight the Cybermen, though refused to team up with the Doctor. Thought to be a villain through and through by the Doctor, Lytton actually surprised the Doctor in the latter appearance by having a somewhat Heroic Sacrifice.
- Badass Normal: Expanded universe media confirmed that he's just a normal human, although one born in an alien planet, which makes the fact that he held his own against the Daleks and the Cybermen, the two most persistent enemies the Doctor has ever had, all the more impressive.
- Cybernetics Eat Your Soul: Partially Cyber-Converted into a Cyberman during his final encounter, Lytton experienced this one personally.
- Fingore: He gets his wrists crushed by the Cybermen.
- HeelFace Revolving Door: Though it's mostly a front.
- Heroic Sacrifice: Rather heroic for the character, as he was partially turned into a Cyberman at the time and near-death.
- Only One Name: Commander Lytton had only one name in the televised adventures of the Doctor, but the novelization of "Attack of the Cybermen" gave him the first name of "Gustave". The story also goes further in-depth on Lytton's character, even expanding his relationship with the Doctor somewhat.
Morgus (Fifth Doctor)
The corrupt chairman of the Sirius Conglomerate, Trau Morgus was responsible for the extraction, processing and distribution of Spectrox on Androzani Minor. He engaged in many illegal business practices, up to and including murder, in order to maximize profits.
- Aside Comment: He addresses the camera directly on occasion. This was a result of the actor misinterpreting the stage directions, but it recalls the Jacobean theatrical tradition of the Aside Comment, and so gives the character an air of Shakespearean villainy.
- Aside Glance: He occasionally addresses the camera.
- Bastardly Speech: He uses Patriotic Fervor slogans while plotting treason and preaching high-minded virtue while Kicking the Dog.
- Big Bad: Serves as this for his only appearance as he's arguably the story's most irredeemable and prominent villain, but notably he never actually meets the Doctor face-to-face.
- Corrupt Corporate Executive: Deliberately sabotages and manipulates his own production in order to keep the market price of Spectrox high. He also has homeless and unemployed people sent to the labor camps he owns, who became unemployed due to his deliberate sabotage of his factories.
- Corrupt Politician: The President of the (equally corrupt) Presidium.
- Creepy Monotone: He constantly speaks in a hushed, sullen tone that hardly ever fluctuates.
- Humiliation Conga: He loses all his wealth and power during the final episode, in quick succession.
- I Reject Your Reality: He is irrevocably convinced that the Doctor and Peri are government agents trying to topple his schemes. Granted, there is little evidence to the contrary and the Doctor is most definitely a spanner in his works, but this incorrect assumption ultimately leads to his downfall.
- Lack of Empathy:
- He leaves his business partner for dead, deliberately causes "accidents" that kill his workers and personally murders his superior, all for the pursuit of profit.
- It is implied that he only saw Sharaz Jek as an obstacle and didn't quite understand just how much Jek hates him. He believed that Jek would back down from a gun pointed at him, or that a bullet would slow him down. He was very wrong.
- Names to Run Away From
- Properly Paranoid: Yes, there was indeed a government agent trying to expose him. It just wasn't the Doctor, or anyone else he suspected for that matter.
- Red Oni, Blue Oni: The Blue to Sharaz Jek's Red.
- Sesquipedalian Loquaciousness: Even though he constantly talks in a sullen tone, he has a very good vocabulary and knows exactly how to use it.
- Villain with Good Publicity
- War for Fun and Profit: Deliberately keeps the Spectrox war going, as it keeps up the market price of the drug.
Sharaz Jek (Fifth Doctor)
The arch-enemy of Morgus. Sharaz Jek used to be Morgus' business partner, using his androids to extract lethal Spectrox from Androzani's underground tunnels. After Morgus betrayed him and left him for dead in a mud geyser, Jek started a one-man campaign of revenge and used his army of androids to sabotage Morgus' operations.
- Anti-Villain: Jek is an admitted mad terrorist who only wants to see Morgus dead, but compared to the other villains in his story he's almost a saint.
- Cool Mask
- Died in Your Arms Tonight: Jek dies in the arms of his final android as his headquarters burns.
- Evil Is Hammy: His raving and scheming is almost Shakespearean.
- Evil Laugh
- Gadgeteer Genius: His army of androids is evidence enough.
- I Have You Now, My Pretty: Falls in possessive, violent love with Peri. It starts off as unsavory, but eventually it becomes fuel for a HeelFace Turn.
- I Was Quite the Looker: Played for Drama when he goes into various How the Mighty Have Fallen rants.
- Mad Scientist: Even his enemies acknowledge the brilliance of his androids.
- Malevolent Masked Man: Wears a head-covering mask to conceal his disfigurement from the mud geyser.
- My God, What Have I Done?: Becomes remorseful when all of his androids are destroyed in the final skirmish and he learns that Peri is dying of Spectrox Toxaemia, as he could have sent an android into the dangerous caves to find the antidote.
- Never My Fault: Blames Morgus for everything bad that happens.
- Noble Demon: He treats his prisoners like guests and doesn't do harm to people who haven't wronged him first.
- One-Man Army: In a sense. Jek is only one man, but his android army is sufficient enough to shunt his drug war into a stalemate.
- The Power of Hate: When he finally comes face-to-face with Morgus again, his hatred is so immense that he walks through a hail of bullets to kill him with his bare hands.
- Red Oni, Blue Oni: The Red to Morgus' Blue. Jek is prone to violent raving, Morgus has a Lack of Empathy.
- Redemption Equals Death: He dies upon saving Peri and the Doctor.
- Right for the Wrong Reasons: Yes, Morgus is a diabolical bastard who must be brought down. Jek's only motivation for wanting to kill him is for the sake of his own selfish revenge.
- Roaring Rampage of Revenge: His biggest priority is bringing Morgus down.
- Stalker with a Crush: He quite clearly has the creepy kind of hots for Peri, doing things like chloroforming her, stroking her face while she's unconscious, and carrying her around in his arms (again, unconscious) while whispering "so beautiful... so beautiful...". The fact that he also dresses entirely in black leather really doesn't help.
- Tragic Villain: He's a cruel, possessive terrorist, but only because of Morgus' betrayal. He goes into a lengthy villain monologue to Peri over how he used to be an optimist, but the trauma from the incident caused him to see the ugliness in everyone. He wants to keep Peri for himself because she's the only light in the darkness for him.
Mestor (Sixth Doctor)
- Grand Theft Me: This is one of his powers.
- Planetary Parasite: His species devastated entire planets, but their eggs cannot hatch unless they are seared by a supernova first.
- Too Dumb to Live: If he had just possessed the Doctor like he said he would, Mestor would have won. But instead, he decided to possess Azmael, a more experienced Time Lord, ultimately leading to his death.
Sil (Sixth Doctor)
A Mentor (read: lizard-slug-alien) and corrupt capitalist, Sil was a perfect compliment to the 1980s, and a good foil for the Sixth Doctor. His first episode had Sil bilking an entire planet out of billions because he could, while his final appearance so far left Sil as an understudy to a quickly-evolving member of his own species named Kiv... who then stole Peri's body for his own. Sil may be dead, but a script the Who crew was forced to discard during the 18-month hiatus of Doctor Who would have had Sil teaming up with the Ice Warriors note too, while a script pitched for the never-produced Season 27 would have had Sil showing up with the Autons and UNIT. Until he shows up again in an actual, televised episode, however, we still don't know if he survived.
- Author Appeal: Sil is a pretty good character concept for the money-oriented 1980s, which was the intent of his creator.
- Bad Boss: Threatens to kill an underling for wetting him down with a spray bottle too roughly.
- Bastard Understudy: To Kiv in "Mindwarp", technically... though Kiv seems to have slowly lost it as the story progressed.
- Con Man
- Corrupt Corporate Executive: The basis for his whole character.
- Maniac Tongue: Has a habit of flicking his tongue out as he laughs in a reptilian fashion.
- Manipulative Bastard
- Mars Needs Women: Averted; he doesn't exhibit any interest in Peri, but when the cell mutator turns Areta reptilian, he says she is "almost attractive."
- Put on a Bus: It's unknown what happened to him after "Mindwarp", not helped any matters by the story being already surreal.
- Reptiles Are Abhorrent: Well, more like amphibians, but Mentors are aquatic and need constant spraying. They're also ruthless in their pursuit of money, especially Sil.
- Villainous Glutton: Known for constantly chowing down on marsh-minnows, not to mention his rather gross Evil Laugh.
The Kandyman (Seventh Doctor)
A robot who enjoys torturing and killing his victims using candy and sweets. The Seventh Doctor and Ace encountered the Kandyman on the human colony world Terra Alpha, where he acted as chief torturer for the despotic Helen A.
- April Fools: On April Fools' Day 2010, it was announced that the Kandyman was to be the Big Bad of Matt Smith's first series as the Doctor!
- Drowning Pit: It seems his favourite method of execution was trapping the victim in a tube and filling the tube with fondant, drowning them. The flavour of the fondant varied, Helen A's favourite was strawberry.
- Evil Chef: He uses confectionery as a means of execution.
- The Evil Genius: The Kandyman acted as this for Helen A, being her chief torturer and a scientist.
- Evil Has a Bad Sense of Humor: Sadistically murdering innocent people with sweet foods is hilarious!
- Hoist by His Own Petard: The Kandyman is eventually destroyed by his own "fondant surprise".
- Homoerotic Subtext: "The Happiness Patrol" is full of this. In particular, the Kandyman and his creator, Gilbert M, act like a married couple whose relationship has long since gone sour. Once the Kandyman is destroyed, Gilbert runs off with Helen A's husband to start a new life together somewhere else.
- Mad Artist: A mad culinary artist.
- Robotic Psychopath: Extremely sadistic and cruel.
- Weaksauce Weakness: He can be rendered immobile with a quick spray of lemonade to his feet.
Revival Series Debut
Cassandra O'Brien.Δ17 (Ninth and Tenth Doctors)
Lady Cassandra O'Brien.Δ17 was a human in the far future. Along with other rich and powerful peoples of the universe, Cassandra was on Platform One, a space station orbiting Earth five billion years in the future, set up to witness the final destruction of the planet by the expansion of the Sun. When the Doctor destroyed her body, she retreated into a hospital back room and waited for a chance to reappear. Rose was that chance, and Cassandra merrily took over Rose's body and mind for a while. When the Doctor protested, she made the jump to the Doctor's body instead, enjoying every moment of it.
- Alas, Poor Villain: She has a very touching exit, especially after everything she'd done.
- Big Damn Kiss: Gets a proper, long, gorgeous snog with Ten while she's in Rose's body. Ten is absolutely stunned.
- Body Horror: That large sheet of skin connected to a Brain in a Jar is a human being who went through at least a hundred rounds of plastic surgery solely to retain her status as a pure human while the others evolved.
- Body Surf: During "New Earth".
- Brain in a Jar: Attached to an enormous piece of skin.
- Dirty Coward: Abandons Chip to the diseased clones when possessing Rose Tyler. Though she's willing to Face Death with Dignity at the end of "New Earth".
- Fantastic Racism: She's the only pure human. Everyone else is a "Mongrel".
- Irony: Completely accidental, but by freeing all the clones she effectively restarted her race of Pure human beings.
- Last of Her Kind: She considers herself the last "pure" human, and sees the various part-humans as "mongrels".
- Stable Time Loop: During "New Earth" she offhandedly mentions remembering the last time someone called her beautiful. That person was herself, in the dying body of her servant, Chip.
- Transgender and/or Gender Bender: She makes an offhand mention of growing up a little boy.
Blon Fel-Fotch Passameer-Day Slitheen, aka Margaret Blaine (Ninth Doctor)
A member of the Slitheen family who came to Earth as part of their plan to destroy the planet, before being the only survivor by means of an emergency teleport when 10 Downing Street was blown up. Afterwards, she set herself up as the Mayor of Cardiff as part of a plot to use the time-space rift running through the city to power her escape vehicle, which would have destroyed the planet in the process.
- Going Native:"London doesn't care! The southwest coast could fall into the sea and they wouldn't notice! God help me, I've gone native."
- Mayor Pain: She sets herself up as the mayor of Cardiff as part of her escape plan, which would have destroyed the planet as collateral damage.
- Raise Her Right This Time: She is reverted into an egg by the Heart of the TARDIS, and is returned to Raxacoricofallapatorius to be raised by a new family.
- Sole Survivor: Due to her one-person emergency teleport, she was the only one of the Slitheen who came to Earth to escape the destruction of 10 Downing Street.
Henry van Statten (Ninth Doctor)
A self-obsessed billionaire (who reportedly "owns" the internet) Henry van Statten is a collector of all things alien, and has been storing extraterrestrial artifacts in his secret underground bunker in Utah. He thinks he's discovered a life form he calls "The Metaltron", and is obsessed with getting it to talk. Little does he know that he's actually got a Dalek on his hands...
- Bad Boss: Van Statten keeps control via his army of mooks and by memory-wiping his executives on a whim, keeping them in a state of sycophantic terror. Unfortunately, by insisting the Dalek be captured regardless of casualties he alienates his security force, and by breaking down in fear in front of Goddard he loses her respect. Both quickly join forces to depose him after the crisis is over.
- Collector of the Strange: Van Statten collects and studied alien artifacts. Collecting a live Dalek may not have been the best move...
- Corrupt Corporate Executive: His computer company is based on stolen Imported Alien Phlebotinum, including an imprisoned Dalek.
- Dirty Coward: As the Dalek pushes deeper into the compound, van Statten's utter uselessness is brought to bare as he can do nothing but impotently sit in his office and watch his legions of security officers die in vain to defend him. When the Dalek finally breaks in, all he can do is gibber and stammer pathetic appeasements until his escaped torture victim has him backed against a wall.Van Statten: I JUST WANTED YOU TO TALK!
Dalek: Then hear me talk now. EXTERMINATE!
- Evil Is Not a Toy: Van Statten continues to treat the Dalek as the prize of his collection, ignoring the Doctor's warnings.
- Expy: Shares many childish and megalomaniacal traits with his "Jubilee" counterpart, Nigel Rorchester.
- Green-Eyed Monster: After the initial shock of hearing the Dalek's voice for the first time thanks to the Doctor's prompting, van Statten bursts into the room and attempts to provoke the Dalek to talk to him as well, clearly envious of the Doctor being the alien's centre of attention.
- Hoist by His Own Petard: Van Statten wasn't killed, but he surely paved the way for his eventual fate. His policy of using torture on his alien captive caused said alien to go on a murdering rampage when it finally got loose, and his fondness for wiping people's memories and dropping them off in a town starting with the same letter as their last name got turned around on him by his newly appointed second-in-command.
- Internet Incorporated:Adam: Mr. van Statten owns the Internet.
Rose: Don't be daft, nobody owns the Internet.
Van Statten: And let's keep everyone thinking that way, right kids?
- Kick the Dog: Has an aide memory-wiped simply for giving him the wrong answer.
- Laser-Guided Amnesia: He subjected staff he fired to this, and ultimately gets the treatment himself.Goddard: And by tonight, Henry van Statten will be a homeless, brainless junkie in San Diego, Seattle, Sacramento... Someplace beginning with "S".
- Not So Different: The Doctor suggests that van Statten and Davros are very much alike. Van Statten doesn't get that it's meant as a diss.
- No Celebrities Were Harmed: Van Statten was originally named "Will Fences" in a joking allusion to Bill Gates.
- Psychopathic Manchild: Overall, van Statten comes across as incredibly immature, spoiled and entitled. His obsession with hearing the Dalek talk, specifically to recognise and address him, makes him sound like the "Do the Roar" kid from Shrek Forever After.
- Sir Swears-a-Lot: Although "a lot" may be pushing it, American audiences were shocked to hear Henry shout "goddamn" at the Dalek, which would have been the first swear word (but far from the last) uttered in the televised show, albeit a mild one.
- Smug Snake: Van Statten's callous disregard for the lives of his men as the Dalek massacres them, as well as his massive ego, make him completely unsympathetic and detestable. Though ironically, his actor Corey Johnson believes van Statten is misunderstood.
- Withholding the Cure: Van Statten claims to have discovered the cure for the common cold, but isn't letting it out of the labs. "Why sell one cure when I can sell a thousand palliatives?"
The Wire (Tenth Doctor)
An alien criminal who escaped a death sentence by turning into an Energy Being, losing its original body in the process, it made its way to 1953 London and forced a hapless television salesman to help it steal faces and people's brainwaves in order to try and regain a physical form, planning on doing so while millions of people were watching the coronation of Queen Elizabeth II.
- Ambiguous Gender: It takes the form of a female television announcer, but its actual gender is unknown.
- Catchphrase: "FEED ME!"
- Energy Being: It escaped execution by turning into pure electricity.
- Face Stealer: A side effect of it stealing people's bioelectricity, in order to regain strength. It doesn't actually do anything with the faces.
- Large Ham
- Only Known by Their Nickname: "The Wire" is almost certainly a pseudonym it adopted after losing its physical form.
- Spell My Name with a "The": The Wire.
The Abzorbaloff, aka Victor Kennedy (Tenth Doctor)
A green humanoid hailing from the planet Clom, with the ability to absorb and gain the knowledge of any other lifeform. Under the guise of human businessman Victor Kennedy, he takes over LINDA, a group of fans of the Doctor, in a bid to absorb him and gain control of the TARDIS.
- Fantastic Racism: Describes the natives of Raxacoricofallapatorious Clom's twin planet as swine and says that he spits on them. He also looks down on humans, describing their body as a "crude pink shape".
- Fat Bastard: Already a prime example of this as Victor Kennedy, who treats the LINDA members like crap while trying to get them to do his bidding, and it gets turned Up to Eleven as the Abzorbaloff, who is even fatter still and flat-out murderous.
- No Name Given: Whatever his actual name is, it's never stated on-screen. It's Elton and then the Doctor who coin the name "Abzorbaloff" for him.
- Oop North: Has a light northern accent as Victor Kennedy, and a full-fat one as the Abzorbaloff.
- Power Incontinence: Seems to suffer from this, as he orders the LINDA members never to touch him because of his supposed skin condition, presumably out of fear that he'll unwittingly absorb them and blow his own cover. He then suffers this to fatal levels at the end of the story when Elton breaks his cane, and without the limitation field it generates, he gets absorbed by the Earth itself.
- Tastes Like Chicken: Says this word-for-word about Ursula after he absorbs her.
- Voluntary Shapeshifter: Seems to be this, albeit with some limitations. He can switch between his personas as the Abzorbaloff and Victor Kennedy, and in doing so apparently suppress those that he's already absorbed, but can't switch forms quickly enough to prevent Elton and Ursula discovering his identity.
- Wounded Gazelle Gambit: After Ursula threatens to assault him with his cane, he initially reacts with genuine terror likely because such an attack would have broken it, removing the limitation field and killing him before begging for mercy and claiming to be "such a slow, clumsy beast". Something he definitely proves not to be when he absorbs Ursula and then chases Elton.
- Wrong Genre Savvy: Believes from his research that the Doctor will allow himself to be absorbed in order to save Elton's life. While the Doctor is always willing to perform a Heroic Sacrifice as an absolute last resort, that doesn't prove to be the case in this particular encounter, as he's able to have the LINDA members (who are already doomed to eventual full absorption and effective death) perform their own sacrifice to deal with him.
The Racnoss Empress (Tenth Doctor)
- Big "NO!": "MYYYYY CHIIIIIIILDREEEEEEEEENNNNN!"
- Even Evil Has Standards: The Empress feeds Lance to her children because she isn't impressed with him readily abandoning his "wife".
- Evil Is Bigger: One of the most physically imposing Doctor Who villains outside of literal Kaiju such as Kroll.
- Evil Is Hammy: The Empress of the Racnoss, bringing Chewing the Scenery to epic levels. One wonders if the Racnoss actually subsisted on scenery that they chewed up, instead of meat, as they insist.
- Evil Laugh
- Extreme Omnivore: The Racnoss can devour whole planets.
- Giant Spider
- Oh, Crap!: She finally realises exactly what she's up against when the Doctor reveals his true planet of origin.Empress: Roboforms are not necessary. My children shall feast on Martian flesh.
The Doctor: Oh, but I'm not from Mars.
Empress: Then where?
The Doctor: My home planet is far away and long since gone, but its name lives on: Gallifrey.
Empress: [gasps dramatically] THEY MURDERED THE RACNOSS!
- Pungeon Master: The Racnoss Empress. Notable in that she deliberately keeps setting up puns, and Lance and Donna don't play along.
- Time Abyss: The Racnoss date from the early days of the universe, and the Empress has been in hibernation for billions of years. The Time Lords and other ancient races hunted the Racnoss down to near extinction.
- Villainous Breakdown: When the Doctor reveals his true home, the Racnoss Empress goes from gloating to horrified shrieking.
Professor Richard Lazarus (Tenth Doctor)
A genius yet sociopathic scientist who is obsessed with discovering the secret of eternal youth, no matter what the cost...
- Dirty Old Man: He very creepily hits on Martha's sister Tish.
- Freudian Excuse: He claims that his desire to cheat death stems from witnessing the Blitz as a child.
- Immortality Seeker
- It's All About Me: While it can partially be blamed on the degenerative effects of his age reversal machine, Lazarus expresses zero remorse for the many victims he sucked dry over the course of his rampage to maintain his monstrous form. His quest for immortality is entirely selfish and once he regains his youth, he loses any pretence of caring for anyone but himself.
- Meaningful Name: The Doctor lampshades this after Lazarus revives from apparently being killed.The Doctor: Lazarus, back from the dead. Should have known, really.
The Family of Blood (Tenth Doctor)
A family of gaseous aliens who hunted the Doctor and Martha throughout time and space. They could only survive by possessing body after body in short-period bursts, and as such sought to steal the Doctor's regenerative immortality.
- Aliens are Bastards: The Family are extremely sadistic. They murder, taunt their victims, bombard a village of civilians with missiles to draw the Doctor out and, after their objective is complete, they'll take over the galaxy starting with the Earth.
- Arc Villain: Of "Human Nature"/"The Family of Blood".
- Asshole Victim: Their ultimate fate is horrific, but given their sadistic and violent actions it's hard to feel bad for them. Son of Mine's host is also an example, due to being a snobbish and racist Jerkass who went off to smuggle beer.
- Be Careful What You Wish For: They hounded the Doctor across all of time and space to gain his immortality. In the end, the Doctor gave them exactly that and more, just not how they expected...
- Character Tic: All four of them share the habit of taking unusually sharp sniffs. Son of Mine in particular tends to speak sentences in a rapid-fire fashion, typically in threes.
- Creepy Child: Daughter of Mine stares people down with an unsettling blank expression. And she's no less dangerous than the other three, as shown when she disintegrates Headmaster Rocastle.
- Demonic Possession: While not literal demons, they are certainly as vicious. This is how their species operates: they possess any lifeforms unlucky enough to cross their paths and extinguish any trace of the previous occupant.
- The Dreaded: Initially it speaks volumes to their level of danger in the lengths the Doctor went to run from them, by disguising himself as a human and hiding in 1913 England to throw them off the trail. And even then, the Family still found him. Though as the Family learns, the Doctor wasn't running because he was scared: that was his way of being kind.
- Family Theme Naming: Each of them are known by their position in a traditional family followed by the possessive pronoun "Of Mine".
- Fate Worse than Death: At the end of the two-parter the Family is subjected to the fury of a Time Lord, and he punishes them by giving them the immortality they wished for in the most awful way imaginable. The Doctor binds Father of Mine in chains forged within the heart of a dwarf star, traps Mother of Mine in the event horizon of an imploding galaxy, and imprisons Daughter of Mine inside every mirror in existence. Son of Mine's punishment is particularly fitting, in that he is suspended as one of the very scarecrows he animated to watch over England for all of time.
- Grand Theft Me: They steal the bodies of four humans in order to get around, killing the humans permanently.
- Immortality Seeker: Their species has an extremely short natural lifespan, and they seek to instead live forever by stealing the life force of a Time Lord. Eventually, they get their immortality... in the most unpleasant ways the Doctor could think of.
- Large Ham: It's a Christmas hamper of ham with this family. Father, Mother and Son of Mine are prone to Suddenly SHOUTING! and Son shows off many horrific Slasher Smiles.
- Mook Maker: Son of Mine is creates a legion of soldiers by animating the scarecrows scattered around the village.
- Names to Run Away from Really Fast: C'mon, the Family of Blood?
- The Nose Knows: They can smell their prey from light-years away, even across the barrier of space-time. The scent of Time Lord is unique and especially easy to locate. It took the Doctor using the Chameleon Arch to turn himself human to erase his scent.
- Sickly Green Glow: The inside of their spaceship is lit like this. As well, when they're communicating with each other and retrieving memories from their stolen bodies, their faces glow like this.
- Telepathy: Are able to communicate with each other this way, indicated by a green glow on their faces.
- We Are as Mayflies: Their natural lifespan is very short; if they hadn't tracked down the Doctor and Martha they would have died after three months.
Lucy Saxon (Tenth Doctor)
The Master's wife in "The Sound of Drums", "Last of the Time Lords" and returning for an encore in "The End of Time". She was his "faithful companion" until she shot him, after Francine Jones and Jack Harkness were stopped trying to do so by the Doctor.
- All for Nothing: Killed herself and managed to wipe out the cult of Saxon in the act of trying to kill "Harry", but he lived on, albeit very damaged.
- All Girls Want Bad Boys: Lucy is the wife of the Master, the Doctor's Arch-Enemy. How's that for a "bad boy"?
- The Beard: The Tenth Doctor implicitly calls her this, when the Fifth asks him if the Tenth's Master still has a beard.
- Blue Blood: Her connections are one of the reasons the Master married her.
- Chekhov's Gunman: In the most literal sense. She starts up as "not too bright", but ends up shooting the Master.
- Despair Event Horizon: Pal around with the Master and he will quickly destroy your will to live/reasons for existing. Which is very dark, considering how eager and totally unhinged Lucy was to kill herself to get rid of the Master for good... which didn't work.
- The Dog Bites Back: Implied to be the motivation for her HeelFace Turn.
- Evil Counterpart: Of the companions in general, and Rose Tyler in particular.
- HeelFace Turn: Turns against the Master during "Last of the Time Lords", and then further works against him in "The End of Time".
- Heroic Sacrifice/Heroic Suicide: Her last appearance in "The End of Time" had her sabotaging a cult's attempt to resurrect the Master in an explosion that kills her. The Master returns anyway, but the attempt caused him to Came Back Wrong.
- Mad Love: She seemed to be genuinely in love with the Master at the beginning, and it clearly wasn't mutual.
- More Than Mind Control: After glimpsing the end of the universe, Lucy went a bit barmy.
- Not-So-Harmless Villain: Does what the Doctor wouldn't, and kills the Master.
- The Ophelia: She a one point is seen babbling about how the Master showed her The End of the World as We Know It and how it made her believe that there was no point in anything ever.
- Straw Nihilist: The Doctor takes his companion to The End of the World as We Know It to make her appreciate life while it lasts. The Master does so to Break the Cutie.Lucy Saxon: Dying. Everything dying. The whole of creation was falling apart and I thought there's no point. No point to anything. Not ever.
- Taking You with Me: Sabotages the Master's attempt at resurrection and causes an explosion that kills her in the process.
- Took a Level in Badass: The "not too bright" Lucy gets a lot smarter once she's free of her husband's influence, nearly foiling his plan to come back from the dead.
- What Happened to the Mouse?: Averted. "The End of Time" reveals for her part in the Master's crimes she was a given a trial in secret with no jury, and then locked up in prison.
Prisoner Zero (Eleventh Doctor)
An alien shapeshifter imprisoned by the Atraxi. The Eleventh Doctor and Amy had to find it when it escaped to Earth.
- Creepy Child: Takes the form of two girls and their mother and then of the young Amelia Pond.
- Creepy Monotone: Never raises its voice.
- Hoist by Their Own Petard: It just so happens to take over Amy's mind when it needs a quick escape; she is the only person who knows what Prisoner Zero actually looks like and Zero can only take the form of what someone is thinking about. So, the Doctor makes Amy think about its true form.
- Involuntary Shapeshifting: It can take the form of whatever a dormant mind is dreaming. However, it has no control over that.
- Morphic Resonance: Its big sharp teeth.
- Noodle Incident: We never do learn what it did to get sent to prison, though its escape causes the Atraxi to try to destroy a planet in response.
- Psychic Link: How it is able to use dormant minds to take different forms.
- "The Reason You Suck" Speech: Gives the Doctor one about how he has affected Amy's life.
- Shapeshifter Guilt Trip: Takes on the form of a seven-year-old Amy while taunting the Doctor.
- Starter Villain: For the Eleventh Doctor.
- Villainous Breakdown: Is reduced to yelling "no!" repeatedly after realising the Doctor found a way to stop it.
Solomon the Trader (Eleventh Doctor)
A pirate who hijacked a Silurian ark and killed the entire crew in an attempt to claim its cargo, dinosaurs, for himself.
- Ambiguously Human: The year is 2367, and his robots claim they've been on the ark for 2,000 years, since long before humanity acquired space travel. Even given that the robots aren't the most reliable source, this is a universe with a lot of Human Alien species.
- Cane Fu: Solomon uses one of his crutches, which has a sharpened edge, to subdue Nefertiti.
- Death by Irony: Solomon is all about the money, so the Doctor lets him have several very shiny, very valuable objects all to himself. The missiles.
- Evil Cannot Comprehend Good: Solomon assumes the Doctor is only interested in the dinosaurs for their monetary value; the Doctor berates him for assuming everyone lives by the same values as him.
- Evil Cripple: Solomon had a run-in with a raptor when he invaded the ship, and it ate a lot of his leg.
- Evil Old Folks: Solomon, played by the inimitable David Bradley, has been doing this sort of vile act for a long time.
- I Have You Now, My Pretty: Solomon is not nice to Nefi, and she gets very, very genuinely scared. His implied unsavoury intentions call to mind Sharaz Jek (only without Jek's Jerkass Woobie qualities).
- Karmic Death: Solomon really, REALLY deserved being blown up in that ship by missiles. This whole affair was his fault to begin with.
- Kick the Dog: Solomon has several; he orders one of his robots to injure Brian in order to force the Doctor to heal him, he ejected the Ark's crew from the airlock, and, when he decides he wants to sell her, he has the triceratops killed in an attempt to make the Doctor hand Nefertiti over.
- Knight of Cerebus: When he shows up, it starts getting much more serious, as most scenes with him involve showing off what a Jerkass he is with his various Kick the Dog moments.
- One Steve Limit: Averted. Solomon shares his name with an important character from "Daleks in Manhattan"/"Evolution of the Daleks", except that guy was an ally of the Doctor.
- Space Pirates: Solomon is the uncomical, seriously nasty kind. He put out a distress signal so he could board this ship and then killed everyone for their cargo.
- Villains Want Mercy: After committing genocide, threatening to kill everyone unless Nefi becomes his slave and subtly alluding that he intends to rape her, Solomon still expects the Doctor to rescue him. The Doctor refuses.
The Gunslinger (Eleventh Doctor)
A cyborg Kahler Super Soldier who went rogue after remembering who he was, seeking revenge against the scientists who turned him into a monster.
- Anti-Villain: The Gunslinger isn't evil; he just wants revenge on the people who made him a monster.
- The Atoner: The Gunslinger decides to become Mercy's protector once his purpose is fulfilled.
- Bait-and-Switch: The episode also opens with a monologue about a "guardian angel who fell from the stars". It turns out to be the Gunslinger, not the Doctor.
- Cyborg: The Gunslinger looks half-man and half-machine, with an Arm Cannon and a robotic Eyepatch of Power balanced out by a more human hand and eye.
- Everyone Calls Him "Barkeep": The Gunslinger, to the people of Mercy.
- The Fettered: The first hint of the Gunslinger's real personality is his refusal to endanger an innocent person. He still sticks to this or, at least, Wouldn't Hurt a Child after Isaac takes the shot he meant for Jex.
- Flash Step: One of the Gunslinger's powers. He uses it to quickly cover distance without breaking his slow, menacing stride.
- Implacable Man: Nothing will stop him from hunting Jex.
- Living Forever Is Awesome: The Gunslinger spends four generations as sheriff of Mercy and hasn't aged a day. This implies he'll protect it forever. It's also awesome in regards to his religion. Imagine how many souls he'd have to carry to reach the mountain top.
- No Place for Me There: The Gunslinger believes he has no place in the world once his war is over. The Doctor convinces him otherwise.
- Not So Different: From the Doctor; another ordinary man who became a monster in order to save a world ravaged by war.
- Roaring Rampage of Revenge: It's mentioned that he hunted down and murdered the other scientists who experimented on him Jex is the last.
- Shout-Out: The Gunslinger is a cross between the Terminator and Yul Brynner's Gunslinger from Westworld. His Stat-O-Vision even says "TERMINATE". By the End he has become more like RoboCop once he decides to be Mercy's protector.
- Was Once a Man: It's shown that he underwent cyborgification in the prequel.
- Weird West
- What Have I Become?: Implied to be the reason why the Gunslinger went rogue, after battle-damage led him to remember who he was and what Jex and the other scientists had done to him.
- Wouldn't Hurt a Child: Even while hunting Kahler-Jex, he will never harm an innocent.
Half-Face Man (Twelfth Doctor)
The main antagonist of "Deep Breath", the Half-Face Man is a robotic drone using human skin and organs to rebuild himself and his race. His ship, the SS Marie Antoinette, crashed into Earth millions of years ago, leaving him and his crew stranded on the planet. His business, Mancini's Family Restaurant, is a front for his organ harvesting, and his ultimate goal is to make it to The Promised Land.
Strangely enough for such an important character, he isn't even named in the episode, but the name "Half-Face Man" is used for him in the credits and behind-the-scenes video.
- Back from the Dead: Despite falling to his death, he wakes up at the end of the episode to meet Missy in a garden that she tells him is The Promised Land. Actually averted, given The Reveal about Missy and the Promised Land.
- Big Bad: Of "Deep Breath".
- Call-Back: His ship is the sister ship of the SS Madame de Pompadour from "The Girl in the Fireplace", and he's a variant of the clockwork robots from that episode.
- Cyborg: Using human flesh and organs to become more humanoid.
- Disney Villain Death: He falls to his death out of the escape pod, but is brought back to life by the end of the episode.
- Driven to Suicide: Possibly. He falls to his death, but whether he jumped or was pushed is left ambiguous.
- Exactly What It Says on the Tin: He's a man with half of a face.
- Eye Awaken: At the end of the episode, after his supposed death.
- Facial Horror: The left side of his face is missing, and the entirety of his eye is exposed.
- Impaled with Extreme Prejudice: He winds up like this, on Big Ben no less.
- The Promised Land: His ultimate goal for his race. He gets there in the end. Supposedly.
- Time Abyss: It's indicated that the Marie Antoinette was flung into the past and crash-landed on Earth before the K-T extinction event, over 65 million years ago, making the Half-Face Man ancient.
The Skovox Blitzer (Twelfth Doctor)
An alien battle robot that wound up in London, in the vicinity of Coal Hill School, with the potential to kill everyone on Earth.
- "Awesome McCool" Name
- Calling Your Attacks: The Skovox Blitzer calls out everything it does, not just its attacks.
- Crush. Kill. Destroy!: The Skovox Blitzer is a killer robot who speaks in a static and hostile manner."Five stop intruder. Five stop intruder. Problem solution destroy."
- Imperial Stormtrooper Marksmanship Academy: For a supposedly advanced killing machine, Skovox takes the phrase "spray n' pray" to a great extreme. The only person he manages to shoot is a stationary police officer.
- Informed Ability: The Skovox Blitzer is described as having enough firepower to destroy a planet. In practice, it can't even hit Clara.
- Killer Robot
- Names to Run Away from Really Fast
- Thrown Out the Airlock: The Doctor pitches the deactivated Skovox out the TARDIS doors and into space.
Gus (Twelfth Doctor)
Gus is the AI aboard the Orient Express in Space, and was programmed to collect data on the Foretold.
- Affably Evil: Always polite and cheerful, even as he sucks the air out of the Orient Express to asphyxiate everyone aboard.
- Expy: He's quite similar to Ash from Alien. He has an ulterior motive unknown to the rest of the crew that involves harnessing the power of a dangerous being to be used as a weapon, the difference being that Gus actually succeeds in his mission.
- High-Class Glass: See the picture. His digital avatar has a monocle.
- Karma Houdini: Gus' creator goes unseen and unpunished, a rarity amongst Who villains (though he may be an Arc Villain).
- Pragmatic Villainy: Gus kills a whole train car full of people to get the Doctor to cooperate. And when the Doctor tries to track the signal back to the source, it just blows up the whole train.
- You Have Outlived Your Usefulness: Pulls this when the Doctor solves the mystery of the Foretold.
The Foretold (Twelfth Doctor)
The Foretold is a creature of ancient legend; those who see it are marked for death, and those who see it have only 66 seconds left to live. It always appears in the vicinity of an ancient scroll, a scroll left on the Orient Express where the Doctor and Clara decided to board. The monster is impossible to kill, impossible to run away from and it is impossible to say who is the next victim. The truth of it turns out to be far more bizarre; it's actually a soldier who has been alive for a while, and the malfunctioning technology it's attached to is keeping it alive and forcing it to fight for a war that's been over for several millennia.
- Anti-Villain: It's really just a soldier that doesn't know it's fighting a war that has been over for centuries.
- The Dreaded: It's basically death personified.
- Implacable Man: The creature is nigh impossible to kill, much less fight against. It's Immune to Bullets, any sort of weapon thrown at it just passes right through it, and it's impossible to run away from. The Foretold will chase after you no matter what you do and it will kill you.
- Intangible Man: Weapons can't touch it.
- Invisible to Normals: Only shows up for people it has marked for death.
- Just Following Orders: The Foretold is a soldier just doing what it's told.
- Life Drinker: How it kills its victims. It sucks all their bodily energy, such as those that their cells produce, and leaves them completely lifeless.
- Mummy: Being chased down by an indestructible Super Soldier is bad enough; it's even worse when it looks like a rotting, wheezing corpse wrapped in bandages.
- Not Evil, Just Misunderstood: It's merely a soldier doing its duty.
- Our Monsters Are Different: For one thing, it's a millennia-old soldier being kept alive by malfunctioning tech.
- Super Soldier: Described as such by the Doctor. The Foretold is indestructible, Immune to Bullets, and can follow its victim no matter where they go. Also there's the fact that it's a soldier that fought in a war that ended long ago.
- Tragic Villain: The Doctor implies this, given that he's forced to remain alive for centuries after the war ended.
- Touch of Death: Its modus operandi.
- Villain Teleportation: Its victim can run as much as they like, the Foretold will always appear next to them and kill them.
- Zombie Gait: Slowly shambles towards its victim, which makes it all the more scary.
Seb (Twelfth Doctor)
Seb is Missy's right-hand man, often meeting new deceased people when she's too busy. He's known to be sarcastic, affable and enjoys cracking jokes; often at inopportune times. He greeted the officer from "The Caretaker" and Danny Pink after they both die and "helps" them get acquainted to the "Afterlife", aka the Nethersphere.
- Affably Evil: He does help Missy create her Cybermen army and even seems to enjoy what he does, but he's still polite, charitable and upbeat. He helps the deceased, offers Danny a coffee and when he gives Danny his iPad to delete his emotions and thus turn him into a Cyberman he doesn't pressure or threaten him, instead giving him a choice. He even does it in a way that makes it seem like a favour. Heck, even Chris Addison himself has called him "polite and charming". It seems that Missy created him to be affable to lull deceased people into a false sense of security so that they would delete their emotions.
- A.I. Is a Crapshoot: Averted, as he does exactly what he's programmed to do and doesn't revolt against his master. But he's still working for a bad guy.
- Ambiguously Evil: It could be argued that he's not actually a bad guy as he was created with "evil" intentions, kind of like how a computer virus isn't evil, only its programmer.
- Deadpan Snarker: His quote above? That's just one of many of his sarcastic quips, jokes and affable demeanour.
- I Can See My House from Here: Says this when Danny looks out his office window and sees the inside of the Nethersphere. Then he apologizes since it probably wasn't helping.
- Squee!: What ultimately gets him killed by Missy, since he was already annoying her and that was just the final straw.
Colony Sarff (Twelfth Doctor)
- Bilingual Bonus: "Sarff" is Welsh for serpent.
- Body Horror: Literally made of snakes, a lot of them.
- The Dragon: To Davros. It's never really explained what exactly Sarff is, why he's working for Davros or why the Daleks tolerate an alien's presence on Skaro. However, given how unusual Colony Sarff is, it's possible he's one of Davros' genetically engineered creations.
- The Face: The large central snake does all the talking for the other snakes that make up Colony Sarff, but he is not their leader. He just announces the consensus.
- Hive Mind: He is a composite creature of many snakes who have joined minds. He's also a democracy.
- Killed Off for Real: Colony Sarff (or, at least, the largest snake that makes up his collective) is killed when Missy shoots him with a detached Dalek gunstick.
- Large Ham: "Wheeere izzzzzz the Doc-tah?"
- Reptiles Are Abhorrent: A villainous serpent. Notably, when he reveals his true form, the medieval locals of 1138 immediately flee in terror.
- The Worm That Walks: Colony Sarff is a giant snake surrounded by smaller snakes.
Fisher King (Twelfth Doctor)
- Badass Baritone: Has a deep menacing voice, thank Peter Serafinowicz, the voice of Darth Maul, for that.
- Big Bad: Of "Under the Lake" and "Before the Flood".
- Dead All Along: Due to the Timey-Wimey Ball nature of his two-part episode, the Doctor and Clara arrive on Earth in 2119 to be attacked by his ghostly minions, which prompts the Doctor to go back to 1980 and fight and kill him in that timeline, then hide in the Fisher King's own coffin when he is buried at sea and come back in 2119 the long way; the ghosts were accidentally activated by the humans who found said coffin but the Fisher King was never truly a threat because he had been killed long ago... From a Certain Point of View.
- Defiant to the End: When the Fisher King sees the incoming flood that's about to crush him, he stands and roars at it until it crushes him.
- Evil Is Bigger: He's an imposing alien warlord that stands at about 8 feet tall.
- Evil Plan: The Fisher King's plan was to use the hijacked souls of the dead to transmit a message to his people so they would come and invade Earth.
- Faking the Dead: It was believed that he had been killed by the Arcateenians when they liberated Tivoli from his tyrannical rule. However when his body was transported to Earth to be buried, it turns out he was still alive and was using the opportunity to set another invasion plot in motion.
- Fisher King: It's in the name. He intended to summon his armada so they would drain the planet of its oceans and subjugate humanity. According to this behind-the-scenes featurette, the Fisher King originally hails from an arid, desert-like place, which helps explain the meaning behind his name.
- Spikes of Villainy: His armour and body have several curved spikes on them.
- Sufficiently Advanced Aliens: His race may not be Time Lords, but they have the technology to manipulate souls, something even the Doctor thought was impossible.
Bonnie the Zygon (Twelfth Doctor)
A radical Zygon who, unhappy with the treaty between Zygons and UNIT, seeks to start a war so that Zygons will have the "right" to exist as "themselves". As the commander of the rebels she infiltrates and undermines UNIT by kidnapping Clara and assuming her appearance.
- Big Bad: Of "The Zygon Invasion"/"The Zygon Inversion".
- Didn't Think This Through: As Twelve points out, she didn't put a lot of thought into her "revolution".
- Does This Remind You of Anything?: She has a lot of analogies in her characterisation to ISIS.
- Easily Forgiven: Twelve forgives her for all the mayhem she causes. Having been responsible for far, far worse atrocities as the War Doctor in the Last Great Time War, he understands her way of thinking. (Not for nothing do the Osgood Boxes resemble the Moment.) This is an invoked trope, as he deliberately forgave her to break the cycle of vengeance.
- Fluffy the Terrible: Yes, the leader of a Zygon uprising is named... Bonnie!
- Hair-Trigger Temper: Is quick to anger when something does not go her way.
- HeelFace Turn: At the end, though she takes a lot of convincing from Twelve to get there.
- Hypocrite: She despises humans for making Zygons hide their true form, but she spends her entire arc disguised as Clara even in the presence of other Zygons. Not to mention, she has a human name!
- I Did What I Had to Do: Claims this, though the Doctor isn't taking it.
- It's All About Me: She says at one point that all Zygons who do not share her views should not be allowed to have that option.
- I've Come Too Far: She believes she's come too far to repent until Twelve convinces her otherwise.
- Karma Houdini: Despite being responsible for the deaths of a lot of Zygons and UNIT personnel, she receives no punishment.
- Psychopathic Manchild: Twelve calls her a tantrum-throwing child who doesn't know what she wants; indeed, she throws a lot of actual tantrums when things don't go her way in "The Zygon Inversion".
- The Reveal: It's only in the final minutes of "The Zygon Invasion" that the audience and other characters even learn of her existence, as she has been most convincingly impersonating Clara for the bulk of the episode!
- Villainous Breakdown: She loses it when she finds out the Osgoods and later the Doctor have tricked her with regards to the Osgood Boxes.
The Veil (Twelfth Doctor)
A cloaked and hooded figure, the Veil is a representation of the Doctor's deepest, most intimate fears. Based on a childhood memory the Doctor had of a dead Gallifreyan woman, who was covered in a veil and left to rot the in the hot sun, this unstoppable figure hunts the Doctor relentlessly through the clockwork castle he finds himself trapped in during the events of "Heaven Sent", and it has only one purpose: to kill the Doctor.
- Bedsheet Ghost: The Veil resembles one due to wearing veils, as it's based on the Doctor's memories of a veiled corpse he saw while young.
- Clockwork Creature: The Veil turns out to be this, matching with the rest of the castle's nature.
- In the Hood: The Veil wears a dusty robe that conceals virtually its entire body, including its face the key visible parts of it teased in the trailers are its gray, mottled, clawed hands. It bears a strong resemblance to the Grim Reaper. It's inspired by a bad memory from the Doctor's childhood of seeing a dead, veiled woman surrounded by flies, and is effectively an embodiment of his fear of death.
- Ominous Walk: The Veil constantly walks at the same pace towards the Doctor. It has a limp, meaning every step is a thump.
- Robotic Reveal: When the Doctor finally breaches the wall, the Veil is revealed to be a clockwork, falling into a pile of gears.
- The Speechless
- Threshold Guardian: The Veil serves as the Doctor's opponent in the Belly of the Whale. It is something he must overcome to reach the outside world.
Lord Sutcliffe (Twelfth Doctor)
A wealthy noble and businessman of the Regency era who plans to use the tourist-attracting Frost Fair to feed attendants to a massive serpent located beneath the ice of the Thames to sell it's excrements as fuel.
- Aristocrats Are Evil: An incredibly unpleasant nobleman who embodies the absolute worst impulses of his social class.
- Card-Carrying Villain: Sutcliffe embodies this trope so much the only thing missing is a classic mustache twirl.
- Corrupt Corporate Executive: He profits off feeding people to a serpent and has no moral qualms with doing so.
- Dead Hat Shot: His hat flies off him as he's pulled under by the serpent-fish himself.
- Humans Are the Real Monsters: Despite the Doctor and Bill's original belief that Sutcliffe is an alien, he turns out to be completely human; the giant serpent in the Thames is his prisoner and not openly malicious, just an animal eating the food that comes its way.
- Karmic Death: Devoured by the creature he's been feeding people to.
- Politically Incorrect Villain: The very first thing he does is start racially abusing Bill the instant he sees her.
The Giant Monk (Twelfth Doctor)
The leader of the Monks' invasion of Earth and mind behind the machine. The Giant Monk is tasked with rewriting the history of invaded planets and provides the main link between the consenting victim and the hapless population.
- Battle in the Centre of the Mind: In order to free humanity from the Monks, the Doctor tries to hijack the signal being sent by him to rewrite history. Though he's successful at first, the Giant Monk fights back and overpowers him. Then Bill has a go at it. Though the Monk starts rewriting her memories, he's unable to rewrite a memory of her mother which Bill made up on her own. Seeing this, the Doctor has her think of nothing but that fake memory, which overpowers the Monk and frees everyone.
- Big Bad: As the Monks' leader and main villain of the Monks trilogy even though he only appears in the last episode.
- Evil Wears Black: Unlike the other Monks, he is dressed in black.
- Mass Hypnosis: The main source of the brainwashing of humanity all across the world.
- Non-Action Big Bad: The Giant Monk didn't even appear in the previous two episodes, giving the effect that the Monks had no leader at all. He is immobilized in the propaganda machine and doesn't even seem to notice the Doctor's party. Even when they're directly interfering with him, the best he can seem to do is fight back mentally.
- Ominous Multiple Screens: His throne room has many triangular screens set in its walls which show all the changed history he is broadcasting.
Queen Iraxxa (Twelfth Doctor)
The ruling matriarch over the Ice Warrior colonies hybernating beneath Mars' North Pole, she and her troops are awakened after her sentinel, "Friday", returns to the planet with a group of Victorian soldiers sent to search for her tomb with the promise of gold and riches.
- Anti-Villain: She only antagonizes the heroes at all to protect her own people.
- Fold-Spindle Mutilation: Her armour, as well as those of her troops, are equipped with laser cannons that cause the victim's body to contort around itself.
- God Save Us from the Queen!: Subverted: She is menacing and not above killing her enemies, but has the same sense of honor and duty as any other Ice Warrior. Moreover, she is trying to protect her people from hostile Earthlings. In the end, the message left on the surface of Mars really refers to her rather than Queen Victoria!
- Honour Before Reason: One of the reasons she is so quick to want to kill the humans is because they made one of her warriors their servant, even declaring "Ice Warriors do not serve". This is despite the fact that, as Friday points out, it was a necessary arrangement to free her, and overall he himself doesn't seem to care.
- However, it's her honourable nature that ultimately makes her spare the commanding officer, previously disgraced for cowardice, after he offers his own life in exchange for the lives of his men.
- Proud Warrior Race Guy: Girl, in her case. It works both negatively and positively.
- The Smurfette Principle: She's the first female Ice Warrior ever shown on screen in fifty years. About time, huh? And what better way to commemorate the anniversary of their debut by finally introducing them in the form of the fairer sex?
Tzim-Sha (Thirteenth Doctor)
A hunter from a race called the Stenza, who comes to Earth hunting a specific trophy to make himself the next leader of his people.
- Battle Trophy: He takes a tooth from every person that he kills and implants it in his face.
- Big Bad: He ultimately serves as the main threat of the Series 11 opener and closer, and his actions, mostly his part in Grace's death, provide the arc of the overall series.
- Darth Vader Clone: In his second appearance, in which he is an imposing black-clad bad guy on noisy life support, who is trying to conquer the universe.
- Dirty Coward: A Stenza seeking leadership must make the hunt with no assistance or tools. He uses both. The Doctor even calls him out on it.
- Facial Horror: His face is covered with the teeth of people he's killed.
- A God Am I: After millennia of pretending to be the Ux's "Creator", the power at his disposal caused him to believe he really was a god, at least functionally.
- Hoist by His Own Petard: The Doctor tricks him into absorbing the DNA bombs he'd had his data coil implant in the Doctor and her friends. The data coil he was using to cheat on his ritual hunt. It's likely that had he not used the coil, he wouldn't have been caught at all.
- An Ice Person: The Stenza are a low-temperature species, and he can freeze humans to death with his touch.
- Malicious Misnaming: The Doctor mishears his name as "Tim Shaw" and continues calling him as such for the rest of the episode. Even the credits refer to him as such, and he's called such by the group in later episodes.
Krasko (Thirteenth Doctor)
A racist time criminal and mass murderer who was imprisoned in Stormcage.
- Badass Normal: A thug with a clever brain and dangerous technology makes for a very bad combination.
- Flat Character: He exists to push the plot because he's racist and that's it. No Freudian Excuse, no sympathetic backstory, just a thug with access to time travel and a racist agenda. Justified as the true villain of his episode were racism and bigotry, he's just another mouthpiece for it.
- Greaser Delinquents: He dresses like one and sabotages cars in the story. He's also a white supremacist who hates non-whites and possibly non-humans.
- Hate Sink: Really has to be one of the most despicable villains in all of Doctor Who. He's not a megalomaniac with delusions of grandeur like the Master or Davros, or genetically modified like the Cybermen or Daleks. He's just a thug who hates anybody who isn't white and decides to meddle in the events of history to undo any progress any people of colour make towards equality.
- Hoist by His Own Petard: He's a white supremacist from the 79th century, who gets sent into the distant past with his own time-displacement weapon by Ryan, a black man from the 21st century, which would be the past to Krasko.
- Manipulative Bastard: His whole shtick since he can't kill anybody, just manipulate time in subtle ways to get what he wants in this case, make sure Rosa Parks never inspires the Montgomery Bus Boycott.
- Noodle Incident:
- He was imprisoned in Stormcage for an incident which killed 2,000 people.
- It's never explained how he knows what a TARDIS is, but it's implied it may have something to do with the time machine black market.
- Politically Incorrect Villain: He's a racist who's trying to prevent non-white people from gaining equality.
- Restraining Bolt: Before he was released from Stormcage he was fitted with one to stop him from hurting anybody. This doesn't make him any less dangerous.
- Ripped from the Headlines: It's no coincidence that his episode coincides with a global uptake in public bigotry and hate crimes.
- Smug Snake: Even when he realizes a Time Lord is on his trail, figures out his Evil Plan and wipes out most of his equipment he still acts like a cocky thug convinced he can still win, even as Ryan sends him into the distant past with his own weapon.
- Tattooed Crook: He has a tattoo on his left wrist identifying him as a former Stormcage inmate.
- Trapped in the Past: First, the Doctor destroys his vortex manipulator while he's in 1955. Then Ryan zaps him even farther into the past with his own temporal displacement weapon.
Jack Robertson (Thirteenth Doctor)
- Played by: Chris Noth
A sketchy real estate mogul with a chain of resorts and eyes on a presidential bid.
- Corrupt Corporate Executive: He's a shady businessman who hides a landfill under a luxury hotel.
- Hate Sink: He's a Bad Boss and Dirty Coward who will happily throw even people loyal to him under the bus to save himself, and is ultimately responsible for all of the deaths related to the spiders because his shady business practices created them in the first place.
- Never My Fault: The very epitome of a blame-foisting politician.
- Take That!: One big poke at President Trump. Though funnily enough, he hates the guy.
