First Doctor era debut

    The Celestial Toymaker 

Celestial Toymaker (First Doctor)
Played by: Michael Gough (1966)

The Celestial Toymaker was a mysterious superbeing who ensnared sentient beings in apparently childish games, with their freedom as the stakes. However, the Toymaker hated to lose and every game ended in Heads I Win, Tails You Lose. The First Doctor had encountered him briefly before. He appeared in "The Celestial Toymaker", and would have returned in a sequel entitled "The Nightmare Fair". Due to Executive Meddling, Doctor Who then went into an involuntary eighteen month-long hiatus and the production team scrapped all previously commissioned storylines and decided to start afresh. The Toymaker returned in comics in Doctor Who Magazine, a Past Doctor Adventures novel, and Big Finish Doctor Who audio plays. The Nightmare Fair was eventually released as one of Target's Doctor Who novelisations and adapted to audio by Big Finish.

  • Affably Evil: Unfailing polite to the Doctor and his companions. He doesn't want to kill the Doctor, he just wants to keep him around as his perpetual opponent because his intelligence makes playing games more fun and challenging.
  • Connected All Along: The Expanded Universe reveals that he is part of the Species? Entity? the Black and White Guardians, his true identity being the Crystal Guardian, personification of games and illusion.
  • The GM Is a Cheating Bastard: Downplayed somewhat. He actually does abide by a certain set of rules throughout the story, though that's not to say that going through his games is a pleasant experience.
  • Graceful Loser: Defied. If he loses a game, his world is destroyed, and he simply creates a new one. However the victor is usually destroyed with the old world too.
  • Heads I Win, Tails You Lose: Suicidal Cosmic Temper Tantrum if he loses; And I Must Scream if he wins.
  • Humanoid Abomination: We never find out what the Toymaker actually is, only that's he immortal with god-like powers. In an expanded universe novel, the Toymaker is said to be a Great Old One, alongside Nyarlathotep, Hastur, and others from the Cthulhu Mythos. A young Doctor, Master, and others read about them and being young and impulsive decide to seek him out, totally underestimating his power.
    • Another story claimed the Toymaker was really one of the six Guardians of Time, like the White and Black Guardians. He is supposed to represent dreams and fantasy.
  • It Amused Me: Everything he does is just because he's bored.
  • Monster Clown: He isn't as actively cruel and malicious as a lot of examples of this trope, but he's certainly a horrible person all the same.
  • Physical God: The First Doctor claims that the Toymaker is an immortal and can't be killed. Even if his world is destroyed if he's defeated, he survives and just creates a new one.
  • Psychopathic Manchild: He uses his powers to turn people into living dolls and make them play his twisted games, out of sheer boredom.
  • We Will Meet Again: In his only televised appearance, the First Doctor mentions that the Toymaker is immortal, and that he fully expects to run into him again. Sadly he never did, at least not on screen, anyway.
  • Who Wants to Live Forever?: He's driven to his villainy by the sheer boredom of immortality. He doesn't even mind the Doctor destroying his realm because at least rebuilding it will mean he has something to do.
  • Wicked Toymaker: He abducts people to his little dimension, forces them to play lethal games, and threatens to destroy them utterly if they don't comply.
  • World Limited to the Plot: His story takes place in his own personal dimension, his "toy room".
  • Worthy Opponent: Considers the First Doctor one due to his brain power. It's why he wants to keep him around as his perpetual opponent.
  • Yellowface: Borderline example, in that Michael Gough dressed as a mandarin and adopted the title of "Celestial", a word that the English associated with Chinese culture. But he did not adopt a Chinese-sounding accent or wear makeup.

Second Doctor era debut

    Time Lords 

    The Great Intelligence 

The Great Intelligence (Second and Eleventh Doctors)
Played by: Wolfe Morris (as Padmasambhava) (1967); Jack Woolgar (as Staff Sgt. Arnold) and Jack Watling (as Prof. Travers) (1968); Sir Ian McKellen (2012); Richard E. Grant (as Walter Simeon) (2012–2013)

"Now the dream outlives the dreamer and can never die. Once I was the puppet... Now I pull the strings!"

The Great Intelligence, which usually referred to itself simply as the Intelligence, was a disembodied sentience who attempted to find a body and physical existence. It first (from its own perspective) encountered the Eleventh Doctor, followed by the Second, and it got quite complicated from there.

  • Aborted Arc: "The Web of Fear" strongly implies that there will soon be a third encounter with the Intelligence. In fact, such a story was being worked on under the working title of "The Laird of McCrimmon" (as the name suggests, it would also have been Jamie's farewell story). This was abandoned following Mervyn Haisman and Henry Lincoln falling out with The BBC over the abridgement of "The Dominators", and a dispute over the ownership of the IP relating to the Quarks. Nonetheless, the arc was un-aborted decades later in stories with the Eleventh Doctor.
  • And I Must Scream: Padmasambhava is fully conscious while the Intelligence spends hundreds of years using his body to carry out its plans.
  • Arch-Enemy:
    • To Clara Oswald, who spends most of her reincarnated lives stopping the damage that he did to the web of time.
    • The fact that the Great Intelligence has attacked the Doctor at essentially all points in his lifetime means that he is the third contender for the Doctor's archenemy, alongside The Master and Davros.
  • Bad Boss: Eats the hired hands who obtain samples for it in "The Snowmen", and mindwipes its minions in "The Bells of Saint John" once the Doctor ruins its plans.
  • Big Bad: He's the main antagonist of the second half of Series 7. And for Season 5. (The Cybermen also appear in two stories, but GI appears in more.)
  • Body Surf: One of its goals is to obtain a suitable physical body for itself.
  • Brain Food: Feeds on human minds.
  • The Bus Came Back: Became the main antagonist of Series 7 after disappearing from the show for 44 years.
  • The Chessmaster: He can play the role of a puppetmaster and manipulate countless humans to carry out his endeavours. He is responsible for a large amount of the events in Series 7. As of "The Name of the Doctor", technically he was partially responsible for everything that ever went wrong for the Doctor.
  • Complete Immortality: The Intelligence has no physical form that can degrade or be destroyed. This has allowed it to survive despite losing multiple "receptacles" since the 1800s. Scattering itself across the Doctor's personal timeline, though, is implied to have finally killed it, unless it truly is the consciousness of Yog-Sothoth, in which case it's likely that it simply was reabsorbed into its original body, which exists across the fabric of time and space.
  • Death Seeker: In his final appearance, the Great Intelligence has grown weary of eternal life, and is quite pleased to have found a way to end it. That he can take a cruel revenge on the Doctor in the bargain just makes it all the more irresistible.
  • Disproportionate Retribution: Prior to his appearance as the arc villain of Series 7B, the Great Intelligence was a formidable recurring but not omnipresent threat to the Doctor; certainly not on the same level of personal enmity as the Master, Daleks or Cybermen. Even during his grand comeback in the revived series, the Doctor only foils two of his plans (that we know of). The Great Intelligence's response? Break into the Doctor's entire timestream and replace all of his victories with defeats, an action that would cripple the entire timeline and certainly destroy the Intelligence in the process.
  • Eldritch Abomination: In "The Abominable Snowmen", he was introduced as a monster that existed outside time and space that possessed Padmasambhava through Astral Projection for 300 years. The Expanded Universe even suggests he is the disembodied conscience of Yog-Sothoth.
  • Everything's Deader with Zombies: What he did to Staff Sgt. Arnold, and Edward Travers.
  • Evil Counterpart: Moffat's reinvention of the Great Intelligence is a dark mirror of the Doctor, taking young "companions" it manipulates and feeds on for its own ends.
  • Evil Is Hammy: In "The Snowmen", Ian McKellen's portrayal sees the Great Intelligence pile on a bit of ham, although afterwards, Richard E. Grant sticks to a cold-blooded, Soft-Spoken Sadist performance.
  • Evil Is Petty: To take revenge on the Doctor for his interference in his plans, the Great Intelligence tries to avert every single one of the Doctor's victories throughout his life, not caring in the least that he's destroying himself in the process, or that doing so will mean the end of time and reality themselves.
  • Evil Sounds Deep: Ian McKellen's portrayal has a deep, booming voice.
  • Evil Has Good Taste: Likes wearing Victorian-era dress suits. Its minions in "The Bells of Saint John" and "The Name of the Doctor" also dress in nice suits.
  • Faux Affably Evil: The very image of a polite Victorian gentlemen. Doesn't stop him from eating human minds and treating his minions like dirt.
  • Have We Met Yet?: Meets the Eleventh Doctor, the Second Doctor (twice) and... well, then things get really, really complicated as he is ripped into a million pieces across the Doctor's entire timeline.
  • Hell-Bent for Leather: Wears very stylish leather gloves, and makes a point of grabbing the Doctor's face with them.
  • I Am Legion: Often refers to itself in the plural.
  • Internal Homage: To the Expanded Universe novel Unnatural History, in which the Doctor’s lifeline becomes a scar woven through space and time, which the villain — dressed as a Victorian undertaker — is going to attempt to use to rewrite his life, until the Doctor’s companion (who he’s met before in a different version) saves the day by leaping into it at the cost of her own existence.
  • Interim Villain: The Great Intelligence was the Big Bad for Series 7, the only season of the Eleventh Doctor's tenure without the Silence.
  • It's All About Me: The (self-described) Great Intelligence devours human minds, uses people up and tosses them aside, and shamelessly kills innocent people for the sake of his own selfish goals. He's even fine with reversing all of the Doctor's victories, endangering all of time and space, to end his own life (because he's tired of it) and to avenge himself upon the Doctor.
  • Living Dream: "The Snowmen" suggests the Intelligence is the "darkest dreams" of a lonely, hateful man come to life. Dr. Simeon had his subconscious mind mirrored by alien snow which is implied in the Expanded Universe to be Yog-Sothoth. The Great Intelligence is later forced to separate from Dr. Simeon and possess Yog-Sothoth/the alien snow due to Dr. Simeon having his memories erased, and is later stripped even of Yog-Sothoth when the tears of an entire family take over the Outer God converting him into tears, thus leaving Dr. Simeon's subconscious mind as a being of pure intelligence.
  • Mecha-Mooks:
    • Its Yeti are actually robots, as it realized snowmen weren't going to cut it.
    • Later the walking wi-fi base station "Spoonheads", robots that camouflage themselves to look human.
  • Mind Control: Many of its plots involve brainwashing humans to do its bidding.
  • More Than Mind Control: Dr. Simeon and Ms. Kizlet were fully aware of the Intelligence's influence on them, and yet wished to do its bidding anyway.
  • Nice Hat: Wears a top hat in its Dr. Simeon form.
  • Not Brainwashed: It's revealed that the mind exuding from the alien snow speaking to Dr. Simeon throughout his life wasn't the alien's own mind, but the mirroring of Dr. Simeon's subconscious mind, thus meaning he was doing his own childish bidding; and when his memories were being erased, the Great Intelligence/Dr. Simeon transferred to the Eldritch Abomination that was taking the shape of snow, only to be kicked out of said alien Eldritch Abomination by a grieving family on Christmas Eve.
  • Origins Episode: "The Snowmen" explains how the Intelligence first came to Earth, adding to its debut earlier in "The Abominable Snowmen".
  • People Puppets: Many of the humans its machines brainwash don't remember anything they did while under its control.
  • Perpetual Frowner: The only time we see his Simeon form so much as smirk is right after he proves his point about not having a body.
  • Pet the Dog: Subverted. The Great Intelligence takes the time to say goodbye to Ms Kizlet before wiping her memories, rather than doing it there and then, but given that he's still erasing her entire life, this can hardly be called an act of compassion.
  • Psychopathic Manchild: The Intelligence is a reflection of Simeon's subconscious thoughts. All the loneliness and resentment of an isolated little boy, which he poured into his only friend: a Snowman.
  • Soft-Spoken Sadist: After taking Simeon's appearance, the Great Intelligence never so much as raises his voice, always speaking in a low, chilling tone that displays his immense cruelty.
  • Sore Loser: Wants to undo all the good the Doctor has ever done (which would undoubtedly wreck the timeline) just to get back at the Doctor for being constantly beaten.
  • Taking You with Me: What his plan in "The Name of the Doctor" essentially amounts to. The Intelligence plots to throw himself into a dimensional tear in the Doctor's tomb on Trenzalore and sabotage the Time Lord's every established victory throughout the timestream into a defeat. Although aware that this action would certainly destroy every trace of himself as well, the Intelligence sees it as a worthy sacrifice.
  • Unknown Rival: The Great Intelligence is very much a backseat schemer, manipulating events from the shadows and rarely making his presence known (usually because he has no physical body to interact with). The Doctor has probably thwarted the Intelligence more times than he knows. As a result, the Intelligence has a burning hatred for the Doctor whereas the same cannot be said in reverse. In fact, the Doctor barely even remembers him when he officially returns in "The Snowmen".
  • Who Wants to Live Forever?: Part of his motivation for breaking into the Doctor's tomb in "The Name of the Doctor" is a desire to find a way to end his eternal life.


Third Doctor era debut

    Kronos the Chronovore 

Kronos the Chronovore (Third Doctor)
A being capable of devouring time. Responsible for the destruction of Atlantis on Earth. Expanded Universe materials maintain that Chronovores exist in the same realm as the Eternals, but that the Eternals consider themselves superior.

    Nestene Consciousness 

Nestene Consciousness (Third and Ninth Doctors)
Voiced by: Nicholas Briggs (2005)

Rose: And this living plastic, what's it got against us?
Ninth Doctor: Nothing, it loves you. You've got such a good planet! Lots of smoke and oil, plenty of toxins and dioxins in the air, perfect. Just what the Nestene Consciousness needs.

The actual mind behind the Autons. After a couple of stabs at invading Earth in the Third Doctor's era, they returned in 2005 out of sheer desperation, having lost their "protein planets" in a mysterious war.

  • Ancient Astronauts;
    • The BBV movies said that they buried Nestenes on Earth's ley line sites thousands of years ago.
    • The novelization to City Of Death said they had to abandon an invasion on Earth because plastic wouldn't be invented for thousands of years.
  • Anti-Villain: To a degree, it comes across as this in "Rose". After losing its planets during the Time War, something the Doctor claims he's partially responsible for failing to prevent, it plans to cannibalise Earth out of desperation to rebuild its race, rather than wanting to do so out of malevolence.
  • Barrier Warrior: The BBV movie, Auton 3: Awakening had a Nestene possessed human able to create energy barriers.
  • Combat Tentacles: They nearly throttled the Doctor in "Spearhead from Space".
  • Drop Pod: When invading, small portions of Nestene would be dropped on a planet inside hollow meteors called Energy Units.
  • Eldritch Abomination: According to the expanded universe, the Nestene Consciousness is the offspring of Shub-Niggurath, an actual Lovecraftian creation.
  • Elemental Baggage: The novelization to City Of Death mentions that it had to abandon an invasion because it landed on Earth thousands of years before plastic was invented.
  • The End... Or Is It?: For a sequel chapter RTD wrote for the Lockdown Watchthrough of "Rose" celebrating its 15th anniversary, part of the Nestene escapes its destruction and merges with someone in Westminster. It is implied this person is Boris Johnson, at the time of the story's writing the current Prime Minister.
  • Energy Being: Some episodes have it being an energy being when it's not made from plastic.
  • Genius Loci: The Nestene is completely infused with it's home planet Polymos.
  • Hive Mind: Controlling the Autons.
  • Imported Alien Phlebotinum: The novelization to City Of Death'' says that Scarroth's Latex Perfection mask was made from technology that the NC left on Earth during a failed invasion.
  • Kryptonite Factor: The Ninth and Tenth Doctors defeat him with vials of blue liquid called Anti-Plastic. The earlier Plastic Millennium comic had the Seventh Doctor and Mel defeat it with a similar unnamed substance.
  • Octopoid Aliens: The novelization to Spearhead From Space said they originally were cephalopods before becoming Energy Beings.
  • Starfish Aliens: Whenever it (they?) takes a physical form, it's a decidedly weird one. Sometimes it's a space-squid, sometimes it's just a vat of talking molten plastic.
  • Suspiciously Similar Substitute: To The Great Intelligence. It possesses plastic instead of people or robot yeti.
  • Teleportation: The BBV movie, Auton 3: Awakening had a Nestene possessed human able to teleport.
  • Vestigial Empire: The Pandoric's Box short story said the Nestenes had a massive space empire that Rassilon wiped out with a Galaxy Eater. He knew they weren't completely gone but would never be as powerful as they were.
  • Whatevermancy: It can control plastic.
  • A Wizard Did It: The novelization to Rose says that the Time War altered its history so it was always made from plastic.


Fourth Doctor era debut


Sutekh (Fourth Doctor)
Played by: Gabriel Woolf (1975)

Fourth Doctor: You use your powers for evil.
Sutekh: Evil? Your evil is my good. I am Sutekh the Destroyer. Where I tread, I leave nothing but dust and darkness. I find that good!

Sutekh is the last of the Osirians, a powerful race from Phaester Osiris. Sutekh destroyed his planet and left a trail of destruction across the galaxy. In Egypt 7000 years ago he was imprisoned by the remaining 740 Osirians led by Horus beneath a pyramid, paralysed by a power source from Mars. When archaeologist Marcus Scarman entered his tomb in 1911, Sutekh took control of him, planning to destroy the power source. However, when he was finally escaping his prison the Doctor sent the entrance far into the future, ageing Sutekh to death. Sutekh appeared in "Pyramids of Mars". He also shows up in the Faction Paradox series, though he also appears in the Bernice Summerfield series by Big Finish, both with their own rather exclusive conclusions to him.

  • Always Someone Better: He's so powerful that if he gets loose, not even the full power of the Time Lords will be able to stop him. It took the combined efforts of seven hundred and forty one of his fellow Phaester Osirians to imprison him the first time — Sutekh is that powerful.
  • Ancient Astronauts: The Osirians inspired Egyptian Culture.
  • And I Must Scream: Was physically immobile the whole time trapped in a pyramid. The most he could do was tilt his head slightly. However, thanks to his vast psionic abilities, he could directly influence events from beyond his prison walls.
  • Bad is Good and Good is Bad: How he sees things.
  • Been There, Shaped History: Sutekh's battle with Horus and the last of the Osirians inspired Egyptian mythology.
  • Big "NO!": He lets one of these rip before his death.
  • Card-Carrying Villain: "Your evil is my good. I am Sutekh the Destroyer. Where I tread I leave nothing but dust and darkness. I find that good."
  • Cold-Blooded Torture: Sutekh's bread and butter. He uses his mental powers to inflict excruciating agony on the Doctor while interrogating him about his home planet.
  • Cold Ham: He manages to out-ham Tom Baker without ever raising his voice above a malevolent whisper.
  • Eldritch Abomination: At the time, the Doctor describes him as the worst threat he has ever faced, the greatest time of peril in the history of the Earth, and given his awakening would have rendered the planet a barren wasteland before he spread across the universe to kill everything, his concern was very much justified.
  • Evil Cannot Comprehend Good: If Sutekh's last stab at bargaining with the Doctor is any indication — he offers to spare the planet Earth (just Earth) and give it to him as "a plaything".
  • Evil Sounds Deep: Sutekh's voice is deep and booming, as befits any self-respecting would-be god and Omnicidal Maniac.
  • Invisible Means Undodgeable: His magic.
  • Kneel Before Zod: If you refuse, he'll just psychically torture you into obeying.
  • Knight of Cerebus: He's bad enough to make the Fourth Doctor scared.
  • Last of His Kind: Destroyed his home planet, and the remaining 740 survivors have by now died.
  • Mind over Matter: He uses telekinesis throughout the story to counter his own paralysis; at one point, he even uses his mind to contain the blast from a gelignite explosive. Doubly impressive considering the explosion is occurring in England and Sutekh's pyramid is in Egypt!
  • Mistaken for Gods: The Osirians became the Gods of Ancient Egypt.
  • Near-Villain Victory: He comes scarily close to winning thanks to his minions' efforts, but luckily the Doctor travels back to the mansion just in time to trap him within his own time corridor.
  • Nepharious Pharaoh: He's a Sufficiently Advanced Alien with an Egyptian theme and Mooks disguised as Mummies.
  • Omnicidal Maniac: Sutekh the Destroyer was a Sufficiently Advanced Alien with these tendencies to preclude the possibility that something that could challenge him might evolve.
    Sutekh: The alien who dares to intrude, the humans, animals, birds, fish, reptiles... all life is my enemy. All life shall perish under the reign of Sutekh the Destroyer!
  • People Puppets: He can brainwash his servants so thoroughly that their original personalities are all but dead the moment he enters their minds. The usually compassionate Doctor roundly dismisses any notion that a possessed servant of Sutekh can ever be returned to normal.
  • Physical God: Incredible mental powers, telekinesis even when paralysed, and it is shown if he escaped he would be capable of destroying entire worlds. Not even the Time Lords could stop him.
  • Really 700 Years Old: Really 7000 Years Old.
  • Sealed Evil in a Can: Imprisoned in a pyramid in Egypt.
  • The Social Darwinist: Despite already being one of the most powerful beings in the Universe he takes this to extremes, he wants to destroy all life to prevent something that could kill him evolving.
  • Soft-Spoken Sadist: Starts off as this. Frankly, it's a relief when he breaks out the ham.
  • Tranquil Fury: After the Doctor and Sarah Jane destroy his pyramid-rocket, he is beyond furious but doesn't vocalise it. He creepily and effectively whispers every word, even when torturing the Doctor. Until he's freed, when predictable characterization developments occur.
  • We Can Rule Together: Offers an alliance with the Doctor not once but twice. The Doctor of course refuses.
  • What Is Evil?: Folder quote for Sutekh. He finds spreading destruction to be "good".

    Black Guardian 

Black Guardian (Fourth and Fifth Doctors)
Played by: Valentine Dyall (1979, 1983)

The Black Guardian was an anthropomorphic personification of forces opposed to the powers of light, as embodied by the White Guardian. According to the Expanded Universe, he was, together with the White Guardian and four others, part of the Six-Fold God known as the Guardians of Time.

    Great Vampires 

King Vampire (Fourth Doctor)

Huge space vampires hailing from another dimension and manifesting themselves in multiple forms based on what species or individual were perceiving them, they were accidently unleashed into "our" universe where they soon clashed with the early Time Lords in a conflict that would later became known as the Eternal War. Unbeknownst to everyone except themselves and possibly also the Time Lords, they were actually emanations and avatars of a force of destruction known as the Yssgaroth.
  • No Immortal Inertia: When the Great Vampire is destroyed, the Three Who Rule's thousand years of unlife suddenly catches up with them.
  • Our Vampires Are Different: They were gargantuan winged creatures that could survive in space, feasted on planets and could only be killed by having their hearts destroyed. They were so massive that the early Time Lords that fought them had to invent a new type of ship specifically for hunting them. The only way the Doctor managed to best the one he encountered was by stabbing it with a rocket ship.
  • Viral Transformation: They reproduced like this.

Fifth Doctor era debut


Eternals (Fifth and Seventh Doctors)
Played by: Lynda Baron (Captain Wrack), Lee 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.

  • Always Someone Better: They are this to the Time Lords. The Time Lords considered themselves to be the mightiest, most advanced race in the cosmos, but even their powers were paltry compared to the Eternals', who view Gallifreyans' attempts to master Time a mere curiosity compared to their complete dominion over Eternity.
    • However, they are a little below the White and Black Guardians in the universe's Super Weight scale as the Guardians can offer them powers and desires that even they cannot grant themselves.
  • Blue-and-Orange Morality: The Eternals shown in "Enlightenment", like Striker and Marriner, simply do not understand human/Time Lord morality. Wrack is a bit more of a clear-cut villain, but still has shades of this.
  • Complete Immortality: The Eternals dwell in the domain of Eternity, rather than the smaller one of Time. This means they are unaffected by Time and thus unaging. Another factor is that Eternals cannot be destroyed, only transferred back to Eternity. However, in the Doctor Who Magazine comic Uninvited Guest, the Seventh Doctor might have found a loophole.
  • Creative Sterility: The Eternals exist in a perpetual state of boredom because they lack the imaginative capacities of Ephemerals.
  • Eldritch Abomination: Exist outside of time and space in eternity, have great Reality Warper powers and they are to Time Lords what Time Lords are to other races.
  • For the Evulz: As shown in the Doctor Who Magazine story Uninvited Guest, the more sadistic Eternals sometimes pose as gods and doom whole worlds in the process.
  • Screw This, I'm Out of Here!: Supplemental material states they left reality after the Time War and never came back.
  • Sealed Evil in a Can: They were the ones who locked away the Carrionites.
  • Telepathy: They could use telepathy and create objects from the memories of Ephemerals, but their powers were not limitless and they could not read minds from great distance or from strong minds (though Adrenaline from the mind they're accessing helps greatly).
  • Wacky Racing: The whole plot of their debut serial deals with them ritualistically racing each other in antique-looking sea vessels across our Solar system for Enlightenment.
  • Who Wants to Live Forever?: Eternity is boring, so they have to find something to do to occupy their time.

Seventh Doctor era debut

    The Gods of Ragnarok 

The Gods of Ragnarok (Seventh Doctor)

A trio of statue-like beings who possess phenomenal cosmic power, the "family" manipulate lesser beings into entertaining them in their Dark Circus, allowing them to live as long as they fulfil their craving for amusement.

  • Action Figure Speech: The three Gods of Ragnarok indicate which of them is talking by raising and lowering their arms.
  • Clarke's Third Law: They're an alien species powerful enough to be considered gods.
  • Creative Sterility: Similar to the Eternals, the Gods of Ragnarok are supremely unimaginative but constantly demand entertainment from lesser beings. This is instrumental to the Take That, Audience! satire in their debut episode.
  • Eldritch Abomination: Unfathomably powerful Silicon-Based Life.
  • Evil Sounds Deep: All three have deep, booming voices.
  • For the Evulz: The Gods of Ragnarok were trapped in a parallel dimension (possibly by the Doctor himself) and take over a circus to force people to perform for them, just to alleviate their boredom. When they lose interest in an act, they kill the performer.
  • Noodle Incident: The Doctor's previous encounter with them.
  • Silicon-Based Life: They appear to be made of stone.
  • The Stoic: Any kind of emotion at all is rare. Although as the Doctor continues to test their patience with his parlour tricks, they become increasingly agitated and trigger-happy.
  • Take That, Audience!: The Gods of Ragnarok can be read as this to the general audience at large. In the circus tent, they're presented as a rather dull family with no imagination of their own who just sit disinterestedly in front of a parade of entertainment moaning about how nothing's ever good enough to interest them no matter how creative it is, and anything they vote down is pretty much wiped out of existence. Could also be a Take That! at the producers of the show, never satisfied by entertainers (*cough* such as John Nathan-Turner *cough*) no matter how hard they try to perform.
  • Tennis Boss: The Doctor defeats the Gods of Ragnarok by using the mirror amulet to reflect their energy blasts and collapse the roof of their balcony seat on them.
  • Who Wants to Live Forever?: Like the Toymaker, they are immortals whose prime motivation is boredom.


Light (Seventh Doctor)
Played by: John Hallam (1989)

An Eternal who manifests himself in the form of an angel, Light has made it his fanatical duty to travel through time and space, documenting every single species in the universe in his exhaustive "Catalogue of Life". Light detests change; so much so that that the process of evolution turns him completely genocidal.

  • Archive Panic: Light gets a severe case of this when he tries to catalogue all of Earth's life forms.
  • Camp: Just take a look at his appearance, not to mention his Large Ham tendencies.
  • A Form You Are Comfortable With: Light is not really an angel, or even humanoid; like an Eternal he's simply "naturalised into" human form.
  • Light Is Not Good: Literally. Although Light appears as a heavenly vision of white and gold, his motives are anything but pure, and he soon reveals himself to be insane, murderous and irrational.
  • Our Angels Are Different: As in, they're not really angels. It's more of a case of:
  • Talking the Monster to Death: Light is infuriated by the fact that the Earth has changed, making the inventory he was working on meaningless. He resolves to destroy the Earth so it will stop changing. The Doctor points out the idiocy of thinking that you can stop change, and that everything in the universe is changing, including Light. Light commits suicide because he considers change a Fate Worse than Death.


Fenric (Seventh Doctor)
Played by: Dinsdale Landen (as Dr. Judson) and Tomek Bork (as Captain Sorin) (1989)

An evil entity from the beginning of the Universe that plans to make humans evolve into the Vampiric Haemovores. Defeated, but returns in the 2012 Big Finish audio "Gods and Monsters".

  • Arc Welding: Revealed Ace being transported to Iceworld and Lady Peinforte's magic were his doing.
  • Arch-Enemy: To the Seventh Doctor.
  • Batman Gambit: Plans for his Wolves to open the flask that contains him once again.
  • Bad Future: Trying to force one where humanity evolve into Haemovores. It's not clear whether this has been averted.
  • Big Bad: Serves as this to the Seventh Doctor's era despite not appearing till his third season.
  • Body Surf: Can do this between his "Wolves".
  • The Chessmaster: He and the Doctor, who literally played chess. Though subverted with the Doctor tricking him with a blatantly illegal move.
  • Clap Your Hands If You Believe: Haemovores can be held back by faith.
  • Demonic Possession: How he manifests.
  • Eldritch Abomination: Fenric is supposed to have been something from the dawn of time, possibly even earlier. The Expanded Universe gives us a more accurate identification: Hastur, the Unspeakable One, the Ragged King. YES, that one!
  • Glowing Eyes of Doom: When he takes possession of a new host.
  • I Have Many Names: Fenric has, according to the Doctor.
  • Kneel Before Zod:
    Fenric: The choice is yours, Time Lord. I shall kill you anyway, but if you would like the girl to live... kneel before me.
    Ace: I believe in you, Professor.
    Fenric: Kneel if you want the girl to live!
    The Doctor: Kill her.
  • Meaningful Name: Fenric comes from Fenrir, a wolf in Norse Mythology who would break free at the end of the world. And the Haemovores are called "Wolves of Fenric".
  • Noodle Incident: The Doctor imprisoned him around the 3rd century after tricking him in a game of chess. It's not revealed exactly what happened.
  • Out-Gambitted: He thinks that he's The Chessmaster, but the Doctor has an Ace up his sleeve.
  • Psychic Powers: Despite being imprisoned, he can still transport people through time.
  • Red Eyes, Take Warning: When he possesses Judson.
  • Sealed Evil in a Can: And the can got opened...
  • Stable Time Loop: Apparently trying to perform one. The last original Haemovore, known as the Ancient One, getting transported back from the year 500,000 and spreading poison will enable the Haemovores to evolve. Subverted when the Ancient One performs a Heel–Face Turn and destroys Fenric's host body in a Heroic Sacrifice.
  • Viral Transformation: How the Haemovores are created.
  • You Have Outlived Your Usefulness: When Fenric no longer needs the Haemovores, he orders the Ancient One to kill them all.

Ninth Doctor era debut


Reapers (Ninth Doctor)

Winged dragon-like monsters from the Time Vortex who feed on temporal paradoxes. Completely invincible, the Doctor describes them as being like bacteria infecting a wound in history, running rampant in the aftermath of the Time War now that the Time Lords are gone.

  • All There in the Script: They are never identified by name in-universe; the name "Reaper" comes from the script, as well as other sources such as Doctor Who Legacy and the comic Four Doctors.
  • Clock Roaches: They "sterilize the wound" left by a temporal paradox Rose created.
  • Early Instalment Weirdness: The Reapers feel like an important addition to a show that revolves around time travel, but they're never seen or mentioned after this episode, even in cases where a paradox should lead to their appearance.
  • Eldritch Abomination: They come from outside time, and appear when paradoxes are created to feast, and can't be damaged or destroyed.
  • The Grim Reaper: It's in the name. They even have tails shaped like scythes. Their appearance is appropriate for an episode all about coming to terms with a loved one's death.
  • Insurmountable Waist-High Fence: Despite being flying extra-temporal abominations with teleportation abilities that are said to be potentially universe-threatening, the Reapers are incapable of breaking into a simple stone church. It's somewhat Handwaved as the Doctor states that they have difficulty affecting particularly old things, and once they receive power from a further paradox, they manage to get in easily.
  • Planet Eater: In the event of a paradox, the Reapers will indiscriminately consume absolutely everything in the vicinity of the time wound, including the entire planet that the paradox is localised on.

Tenth Doctor era debut

    The Beast 

The Beast (Tenth Doctor)
Voiced by: Gabriel Woolf (2006)

"I am the rage and the vile and the voracity! I am the Prince and the Fallen! I am the Enemy, I am the Sin and the fear and darkness! I shall never die!"

A being of great power who claims to have fought the Disciples of the Light before the Universe was created, and was later imprisoned on the planet Krop Tor, circling a black hole. Describes itself as the Devil, which greatly upsets the Doctor's belief system, although he ends up using the description himself for lack of a better explanation. It is given the chance to escape when human explorers fly onto its planet and drill through to its cell. Its mind plans to escape by possessing the team's archaeologist Toby Zed, leaving its original body behind in its prison, but is eventually prevented by the Doctor opening the Beast's cell, activating its failsafe and causing the planet to fall into the black hole, along with the Beast and Toby.

  • As Long as There is Evil: See the above quote. Rose decides to put this to the test.
  • Attack of the 50-Foot Whatever: Look at that picture. That's the Doctor between the two pillars standing in front of it.
  • Badass Baritone: Even the Doctor compliments his voice.
  • Badass Boast: Almost everything it says.
    The Beast: This is the Darkness. This is MY domain. You little things that live in the Light, clinging to your feeble Suns... which die. Only the Darkness remains.
    The Beast: I am the sin; and the temptation. And the desire. And the pain and the loss.
    The Doctor: Tell me, which Devil are you?
    The Beast: All of them!
  • Batman Can Breathe in Space: Humans possessed by it can.
  • A Beast in Name and Nature: Refers to itself as the Beast, among other Satanic titles. For good measure, his human hosts even manifest a Mark of the Beast.
  • Big Red Devil: It claims to be Satan, and it certainly looks the part. No sign of a pitchfork though.
  • Body Surf: After screaming orders at the Ood telepathically, it travels into three of them as smoke from Toby to possess the entire hive mind, while still hiding in Toby.
  • Break Them by Talking: Reading people's minds and taunting them by playing on fears and insecurities.
    The Beast: Mr. Jefferson, tell me, sir: Did your wife ever forgive you?
    Jefferson: I don't know what you mean.
    The Beast: Let me tell you a secret. She never did.
  • Cardboard Prison: Averted; its prison was designed to be VERY difficult to get out of, and if broken, it would fall into a black hole before it could properly escape.
  • Demonic Possession: First it possesses Toby after he handles ancient artifacts, then it possesses the empathic Ood. Toby manifests runes on his skin, red eyes and grey lips, but the Ood gain red glowing eyes and speak through their orbs in the Beast's voice.
  • Devil, but No God: Maybe. If you believe that the Beast actually is the Devil, then the proof for a God is that the Beast fought the Disciples of the Light, who possibly could be followers of a God. Also, the Ood mention that "he will rise from the pit and make war on God."
  • Devil in Disguise: When it hides in Toby it sounds like him when it wants to.
  • Did You Just Punch Out Cthulhu?: Rose and Doctor throw a being claiming to be Satan into a black hole.
  • Dug Too Deep: How Humanity and, by extension, the Doctor cross his path.
  • Eldritch Abomination: It claims to be older than time itself, and its origin is logically impossible even by the Doctor's standards.
  • Empty Shell: The Beast's body, as its mind has escaped to possess Toby and the Ood.
  • Evil Is Not Well-Lit: Invoked by the Beast and discussed by the Doctor. The Beast preys on basic, childish fears within people to defeat them, such as fear of the dark. As soon as the humans get the lights in the Sanctuary Base working again they feel better.
  • Evil Sounds Deep: He shares a voice actor with Sutekh.
  • Fantastic Racism: The Beast treats human beings as nothing more than pathetic, fearful monkeys that are no danger to it. The only character it treats with even a hint of respect is the Doctor, and only because he can insightfully analyse it and form a plan to fight it.
  • For the Evulz: Why it kills Scooti.
  • Game Face: As Toby, having red eyes, blue lips and glyphs on his skin.
  • Genius Bruiser: When it faced the Disciples of the Light, it was with that giant monster form. In order to escape its prison the Beast split itself into its Genius and Bruiser parts to let the Genius escape.
  • God of Evil: What it inspires in some religions, as well as war gods and devil figures.
  • I Am Legion: It even says the exact quote.
  • I Have Many Names:
    The Ood: Some may call him Abaddon. Some may call him Krop Tor. Some may call him Satan. Or Lucifer. Or the King of Despair. The Deathless Prince. The Bringer of Night.
  • Leaking Can of Evil: It possesses Toby and dozens of Ood even before its prison door opens up.
  • Legions of Hell:
    • In the Torchwood season 1 finale, Abbadon the "Son of the Beast" is revealed to have been imprisoned in a similar manner in the Cardiff Rift on Earth. In supplementary materials, Tosh speculates that there might be other demons trapped elsewhere in the universe in secret prisons...
    • The Ood serve as this on the space station while his body is chained. They even call themselves the Legion of the Beast.
  • Lovecraft Lite: The Doctor and Rose send its body and mind flying into a black hole.
  • Manipulative Bastard: The Doctor quickly calls out the Beast out on playing on basic fears, such as fear of the dark or an abusive parent.
    Danny: But that's how the devil works.
    The Doctor: Or a good psychologist.
  • Many Spirits Inside of One: Inverted. The single Beast possesses many Ood, as well as Toby, at once.
  • Mark of the Beast: Toby is covered in glyphs that are so old that the TARDIS can't translate them when the Beast possesses him.
  • Maybe Magic, Maybe Mundane: Is he really the Devil, or just a Sufficiently Advanced Alien who happens to resemble our popular conception of the Devil and perhaps was even the basis for ours and other Devil myths? Never established for certain, though the episode hovers closer to the former explanation.
  • Mind Control: His signature power.
  • Mind over Matter: Telekinetically shatters reinforced windows, cuts cables and opens its pit.
  • Mysterious Past: The only hints at the Beast's past are its claims (which can't be trusted or proven), some vague cave drawings the Doctor finds nears its cell, and humanity's own Devil myths.
  • Name's the Same:invoked According to the Great Intelligence, "the Beast" is one of the aliases the Doctor collects over time.
  • Nigh-Invulnerability: It's strongly hinted that the mind of the Beast can never be destroyed, that it will live on in the minds of every being in the universe.
    The Beast: I shall never die! The thought of me is forever: in the bleeding hearts of men, in their vanity, obsession, and lust! Nothing shall ever destroy me! NOTHING!
  • Our Demons Are Different: This one may be the inspiration for all the ones who followed.
  • Outside-Genre Foe: In a strictly sci-fi series, a creature appears claiming to be Satan himself. Even better, there is more evidence for the idea that it really is the Devil.
  • Playing with Fire: Toby breathes fire when the Beast possesses him and is ranting when the Doctor destroys the gravity field, dooming himself, the Beast and the human survivors.
  • Psychic Powers: The Beast possesses telekinesis, technopathy and telepathy, which it uses to attack, possess and terrify the Sanctuary base crew once its mind separates itself from its body. It also foretells Rose's death announcement after the battle of London between the Cybermen and Daleks.
  • Red Eyes, Take Warning: It's a sign that the Beast has taken someone over. He can hide it when he wants to, though.
  • Satan: The Beast claims it is one of his names, and apparently inspired not only Christianity's Devil, but the Devil figures in every religion to have one in the entire universe.
    Toby: It was so angry. It was fury and rage and death. It was him. It was the Devil.
  • Scary Teeth: Big scary demon teeth!
  • Sealed Evil in a Can: It's so powerful it was sealed miles underground the surface of a planet precariously orbiting a black hole, meaning that any attempt to escape would send the Beast and the planet to fall into it. These Disciples of the Light guys really didn't want this guy to escape — and one can see why.
  • Shout-Out: A homage to Event Horizon and Prince of Darkness as well.
  • Slasher Smile: When it gets to do its first kill in eons.
  • Sliding Scale of Villain Threat: At least universal when unbound and possessing its own body. Its mind alone is certainly a planetary threat, possibly greater.
  • Technopath: Voluntarily or not, it makes the A.I. controlled doors, the hologram display, the Ood's speech devices and Rose's mobile phone announce its imminent release.
  • Telepathic Spacemen: A telepathic being from (maybe beyond) outer space.
  • There Is No Kill Like Overkill: If it escapes from its prison, then it falls into a black hole. The Doctor states that the Devil is really an idea shared among societies, so even this may not truly kill it. In any case, the Beast's prison planet falls into the black hole, apparently with its body, while its mind possessing Toby follows it to the same fate.
  • Time Abyss: It existed before the universe, though the Doctor claims that is impossible (it lampshades his Arbitrary Skepticism). Nevertheless he concedes it could have existed at the start of the universe.
  • Ultimate Evil: If the Beast is what it claims, then it is the first and most powerful evil being to have existed, corrupting every sentient being in the universe.
  • Villainous Breakdown: When the Doctor dooms it to fall into the black hole, both the Beast's mind and body rant, thrash and breathe fire.
  • Voice of the Legion: The Ood speak in this when possessed.
  • Volcanic Veins: The veins in its body glow.
  • You Cannot Kill An Idea: Although the Beast is defeated, it still possesses psychic influence over every being in time and space.

    Weeping Angels 

    Midnight Entity 

The Midnight Entity (Tenth Doctor)
Played by: Lesley Sharp, David Tennant (2008)

"It's inside his head. It killed the driver, and the mechanic, and now it wants us. He's waited so long. In the dark, and the cold, and the diamonds. Until you came. Bodies so hot, with blood, and pain."

A strange creature found on the inhospitable planet Midnight, which possesses Sky Silvestry. Its physical appearance is never shown, if it has one at all. While possessing Sky, she repeats everything that is said, then she speaks at the same time as others, before finally focusing on just the Doctor and speaking before him, stealing his voice.

  • Beyond the Impossible: Its very existence is treated as this, especially by the officious Professor Hobbes, who constantly insists that Midnight's xtonic sunlight — which vaporises any organic tissue within seconds — makes the planet absolutely uninhabitable for any form of life. And yet, the entity exists.
  • Demonic Possession: While it doesn't appear to be a demon, its hold on Sky Silvestry is pretty much this.
  • The Disembodied: It's suggested the creature might simply be a disembodied consciousness, as the Doctor asked if it wanted a body. Which would explain how it could survive in xtonic radiation and how it entered Sky's mind, although it doesn't explain how it can knock on the hull and rip the ship apart.
  • The Dreaded: This thing terrifies the Doctor in a way almost no other villain in the history of the show can match.
  • Eldritch Abomination: Manages to achieve this status without any special effects whatsoever.
  • Enslaved Tongue: In the final phase, the entity spoke before the Doctor, who was paralysed and forced to repeat the words calling for his own death.
  • Faux Affably Evil: Once it has the Doctor at its mercy, the entity speaks up, pretending to be Sky, grateful for being freed from a state of helplessness, all in a tone that drips with malevolence.
  • Generic Doomsday Villain: Done effectivelynothing is known about what it plans to do or where it comes from, and it comes off as all the scarier for it. Virtually the only thing we can glean is that it wants a human body to inhabit.
  • Living Shadow: Claude the mechanic spots a shadow running towards the shuttle bus in the irradiated diamond wasteland. Indeed, a slithering shadow can be faintly made out for a fraction of a second which is likely the closest we get to seeing the creature's true form, but it's so brief and indistinct that it could be anything.
  • No Name Given: Not even a nickname, the term "Midnight Entity" comes from the TARDIS Data Core Wiki.
  • Nothing Is Scarier: When the Doctor tells Sky to turn around, any experienced viewer will know that something terrible will have happened to her appearance. The fact that there's no obvious change to her just adds to the fear of the moment. Also on a meta level: we don't know what species it is, we don't know where it came from, we don't even know if it died. All told, we know next to nothing about it.
  • Psychological Horror: The creature is never physically shown, and all the fear mechanism stems from the way its possessed victim behaves.
  • Riddle for the Ages: Just what the frick is this thing? We'll probably never know, but fan theories abound.
  • Smug Snake: Once it has a voice of its own, it revels in the Doctor's helplessness but quickly says too much, cluing the Hostess in to the truth of the situation and earning itself a one-way ticket back out into "the dark, and the cold, and the diamonds".
  • Stop Copying Me: Played for maximum horror. First it repeats you, then it mimics your words in perfect sync... and then it starts talking ahead of you.
  • Thousand-Yard Stare: Perhaps the most unsettling thing about the entity is its piercing, unblinking gaze when it's in possession of Sky's body, not helped at all by Lesley Sharp's Icy Blue Eyes. The way it looks at the passengers alternates between intensely studying every movement they make to dully looking right through them.
  • Ultimate Evil: By the end of the episode, the Doctor has no idea what it was or if it's still out there. He can only recommend that the entire planet be evacuated.
  • Uncertain Doom: It could already survive on the surface of Midnight, so it's not entirely clear if being dragged out there while possessing Sky might have killed it. The Doctor isn't willing to take any chances and makes sure that the entire planet is evacuated and declared off-limits.
  • Woobie, Destroyer of Worlds: Based off what Possessed!Sky said about it, Midnight is not a pleasant place to live. When it realizes that it's going back outside, it lets off an absolutely terrified scream.
    Sky: Cast him out. Into the sun. And the night. The starlight waits. The emptiness. The midnight sky.

Eleventh Doctor era debut


House (Eleventh Doctor)
Voiced by: Michael Sheen (2011)

A sentient and parasitic Genius Loci planetoid that primarily feeds on TARDISes.

  • Badass Boast: Tries one on the Doctor. It backfires.
    House: Fear me. I've killed hundreds of Time Lords.
    The Doctor: Fear me. I killed all of them.
  • Demonic Possession: It rips the TARDIS' soul out of her shell, stuffs her into a human body, and then takes over the shell itself when it finds out there are no more TARDISes.
  • Eldritch Abomination: House lives in a pocket reality at the "bottom" of the universe, hunts and eats TARDISes, and demonstrates a good deal of control over its surroundings — both the asteroid and later, the TARDIS.
  • Evil Counterpart: To the TARDIS; like her, House is an extremely powerful Genius Loci with a number of humanoid beings living on/in it. Unlike the TARDIS, House regards them as entirely disposable People Puppets, and devours any other Genius Loci (usually a TARDIS) unfortunate enough to cross its path — usually, after it lured them there in the first place.
  • Faux Affably Evil: House is perfectly polite and, apparently, friendly, enough to deceive the Doctor into thinking it's a perfectly decent being. As it happens, it never loses that calm and polite tone even after its true nature as a Soft-Spoken Sadist is revealed.
  • Genius Loci: As the Doctor puts it:
    "This asteroid is sentient."
  • Laser-Guided Karma: On the receiving end after the Doctor manipulates it into a fatal error, accidentally bringing all of them, including Idris — the TARDIS' current vessel — into the TARDIS' control room. The TARDIS promptly retakes control, eradicating House, while the Doctor smiles contentedly at the sound of House's dying screams.
  • People Puppets: Has a number who extol its virtues, their current bodies being stitched together from the corpses of dead Time Lords and other unfortunate species, to the point where the Doctor doubts there's anything left of who they originally were.
  • Sickly Green Glow: Represented by this. When it possesses the TARDIS, the normally golden lighting, inside and out, changes to green, most noticeably when it tracks the Doctor, Amy, Rory and Idris to the old console room they're in.
  • Soft-Spoken Sadist: It never raises its voice or loses its level tone, not until it's screaming in pain as the TARDIS gets her revenge. It also spends who knows how long (possibly minutes, possibly decades) psychologically torturing Amy and Rory with Mind Screw after Mind Screw, simply because it was more amusing than killing them — which was why they suggested it, hoping to stay alive long enough to get out/for the Doctor to get them out.
  • Year Inside, Hour Outside: As part of its sadistic illusory mind games with Amy and Rory, it keeps separating the two and makes Amy believe that while only seconds have passed for her, decades have passed for Rory, who appears to have died hating her for abandoning him.


Akhaten (Eleventh Doctor)

Also known as "The Old God", Akhaten is a parasitic, monstrous creature that's as large as a planet. It's so big, in fact, that it has its own centre of gravity, and has several inhabited asteroids surrounding itself. Akhaten awakes from its slumber every thousand years at the Festival of Offerings on Tiaanamat, where it feeds off the memories and experiences of the inhabitants.

  • Eldritch Abomination: Akhaten is actually revealed to be an unbelievably ancient, sentient, planet-sized parasitic monstrosity of immense power with formless features that must be kept asleep, otherwise it will devour everything.
  • Emotion Eater: "Grandfather"/the Old God feeds on emotions and stories.
  • God Is Evil: Akhaten's true nature is a merciless parasite that has to be appeased with memories and kept asleep with Music Magic. When the mummy stirs, the song changes to a much more urgent "never wake from slumber".
  • God Is Good: Akhaten, the sentient planet god of the seven systems, is referred to as "my warrior" and "my hero" in the songs. This suggests that the songs are to assure him that everything's fine and he can continue to rest his "holy head".
  • Genius Loci: It's either a sentient planet or simply a being so gigantic that it might as well be.
  • Phlebotinum Overload: The Old God feeds on the life experiences of others. The Doctor tried to invoke this with his own memories, and came pretty close, but the planet survived that. When Clara offers it "the most important leaf in human history", containing not only the experiences of its owner but all the experiences they could have had, it implodes.
  • Too Spicy for Yog-Sothoth: The Doctor's 1200 years of far flung adventures are not quite spicy enough to bring down Akhaten. Clara's leaf of infinite possibilities does the trick.

Twelfth Doctor era debut

    The Perfect Hider 

"The Perfect Hider"/"The Figure" (Twelfth Doctor)

"Listen! Question: Why do we talk aloud when we know we're alone? Conjecture: Because we know we're not."
Twelfth Doctor

A creature hypothesised to exist by the Doctor: an entity so good at making itself hidden that it is completely undetectable. But it is nevertheless always present, and every other being is subconsciously aware of its existence. Or at least, so the Doctor theorises...

  • Abstract Apotheosis: The creature may be no more than the Doctor's madcap theory, an idea representing his own primal fears dating back to his troubled childhood on Gallifrey.
  • Bedsheet Ghost: It evokes the iconic image of one (although red rather than white) when it rises from Danny's bedspread.
  • Crazy Survivalist: The Doctor speculates that such a creature would have evolved perfect camouflage skills for survival and that one day they might "come a-slithering from under the bed" when they have successfully outlasted every other species. If that's the case, then their patience is certainly to be admired.
  • The Dreaded: Although they may not even be actively malevolent, they are subconsciously feared by every other sentient being in the universe. The Doctor theorises that the only way to make them go away is to let them know your fear. Tellingly, Orson Pink's bunker at the end of the universe has doors with warnings scrawled all over to never open the door because something seems to want to come in.
  • Invisibility: Not just invisible, but the hypothetical creature could make themselves completely undetectable in every sense of the word.
  • Living Shadow: The concept for the creature is loosely based on the "shadow people" phenomena commonly associated with sufferers of lucid dreaming and sleep paralysis who claim to see demonic silhouettes. The Doctor even investigates random people having night terrors across the world to help validate his hypothesis.
  • Maybe Magic, Maybe Mundane: The closest we get to a tangible encounter with it is in a young Rupert (Danny) Pink's orphanage, but as the Doctor duly notes, it could very well have just been another kid hiding under the bedspread to prank Rupert. Alternatively, it wasn't.
  • Nightmare Face: While it's completely blurred out, we do briefly see the creature reveal itself when it removes the bedsheets, and from what we can tell, it's not too pretty. It seems to be bald and incredibly pale, similar to the description of the Floofs (see Self-Plagiarism). However, it could have been a kid in a mask.
  • Nothing Is Scarier: Even more prominently than the Midnight entity, the Hider is so indistinct and unknowable that it may not even exist, but such an impediment makes it no less terrifying.
  • Primal Fear: Represents the basic human fear of being watched by the unknown. Not just human, as it applies to every species, including Time Lords.
  • Riddle for the Ages: Does it actually exist? The episode itself implies that it most likely doesn't. The Doctor's obsession with proving its existence is merely his way of coping with the fact that even he is still afraid of the dark, just like the rest of us. However, the veiled figure in Danny's room and the things outside Orson Pink's bunker may make you think twice...
  • Self-Plagiarism: The concept of creatures that have evolved to be so adept at hiding that they're undetectable was previously used by Steven Moffat in his short story Corner of the Eye. The creatures in that story were identified as Floofs, but the key difference is that the Floofs actually reveal themselves, which is more than can be said for the figure in "Listen".
  • Sole Survivor: Alongside the Doctor himself, Ashildr, the Toclafane, Orson Pink and possibly a few other Eldritch Abominations on this very page, the Hiders (if they even existed in the first place) could be among the universe's last surviving beings before the inevitable heat death collapse, and they decide to finally come out of obscurity Just Before the End, trillions of years in the future. Either way, something was banging on the door of Orson's bunker.
    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.

  • Ambiguously Evil: It's really unclear why they decided to enter our dimension, whether they want to communicate with us, study us or eliminate us one by one. The Doctor ponders this question for a while, but eventually lands on them as aware of their actions, but too callous to care, and banishes the Boneless to their home dimension to keep them from causing any more damage.
  • Eldritch Abomination: Creatures that come from a 2-D plane of existence.
  • First Contact Math: The Starfish Language of 2-Dimensional beings proves too alien for even the TARDIS's Universal Translator to handle. The Doctor had hoped the creatures are a Non-Malicious Monster who are simply so alien and confused by a 3-D world they don't realise they're harming sentient beings. He establishes rudimentary communication with them by using the digits of pi. They respond with the number on the jacket of the man they killed, and then the number of the one they're about to.
  • Flat World: Their universe is two-dimensional, so they're from a very literal version of this trope.
  • For the Evulz: As enigmatic as they are, it is made clear that they are gleefully aware of the harm they're causing.
  • Hidden Agenda Villain: Their motives are left deliberately unclear and many hypotheses are brought up during the episode; perhaps they're here to contact us, kill us all, dissect or study us and don't even know that we require 3 dimensions to survive.
  • Humanoid Abomination: Eventually they take the form of those they've killed when they finally understand 3 dimensions.
  • Known Only by Their Nickname: Their real name is unknown due to being unable to communicate. The Doctor dubs them "The Boneless" since he found "Killer Graffiti" rubbish.
  • Paper People: Comes with being 2-D lifeforms.
  • Starfish Aliens: Beings from a 2-D dimension that are attacking Earth.
  • Starfish Language: The TARDIS is unable to translate their language because being aliens who don't understand the concept of a third dimension are even too bizarre for her standards.
  • Stealth Pun: They're two-dimensional in more ways than one.
  • They Would Cut You Up: Rare alien-on-human example. They turn humans into 2-D and dissect them to understand their bodies so they can become 3D.
  • Uncertain Doom: The Doctor states that some will survive being sent back to their home dimension, though there is no way of knowing if any of the Boneless die on their way back home.
  • Zombie Gait: When they take the appearance of those they've killed, the creatures run after everyone this way. Having a rudimentary understanding of 3D and human anatomy, their walking style is crude and zombie-like.

Thirteenth Doctor era debut

    The Solitract 

The Solitract (Thirteenth Doctor)

An impossibly old form of consciousness, born alongside the universe itself. But its sheer alien nature was a threat, so it was banished to its own plane of existence.

  • Animalistic Abomination: Adopts the form of a frog.
  • Cosmic Flaw: Was born alongside the universe but is mutually incompatible to it, thus both had to be isolated from each other to fully form. Particularly the portal connecting it to the universe spontaneously forms a pocket dimension as a buffer because any kind of direct "contact" between them would destroy them both.
  • Eldritch Location: So eldritch that any kind of interaction with normal space-time, including beings from it, is mutually destructive.
  • A Form You Are Comfortable With: Part of how it lures people into it, but eventually it finds a form it's comfortable with. A talking frog.
  • Genius Loci: The best way to describe it is that it's an intelligent universe.
  • Lotus-Eater Machine: It creates illusions of people's dead loved ones in order to entice them into not leaving.
  • Tragic Monster: It ultimately doesn't mean any harm to the people it abducts, it's simply UNFATHOMABLY lonely. It even is willing to let the Doctor, its last remaining companion, go free for both their sakes.


The Kasaavin (Thirteenth Doctor)

A race of extra-dimensional aliens working with the Master and Daniel Barton on a mysterious plot.

    Zellin and Rakaya 

Zellin and Rakaya (Thirteenth Doctor)
Played by: Ian Gelder (Zellin), Claire-Hope Ashitey (Rakaya)

A pair of cruel alien gods who played bloody games with the inhabitants of a pair of planets. When the people finally got wise to what was going on, they sealed Rakaya inside a prison that neither of them could break. Zellin eventually came up with a plan to free her by targeting the Doctor and her companions...

  • All There in the Manual: According to Doctor Who: Time Lord Victorious, they are both Eternals.
  • Bald of Evil: Zellin.
  • Call-Back: They mention the Toymaker and the Guardians on-screen for the first time in how many years?
  • Detachment Combat: Zellin can detach and regrow his fingers to attack people with and feed on their nightmares.
  • Emotion Eater: Both of them feed on fear.
  • It Amused Me: They make wagers on the destruction of planets, foster wars between species and civilisations, and feed on the nightmares of humans, all as ways to keep themselves entertained.
  • Jerkass Gods: A pair of alien gods from another dimension who like to play horrific "games" with mortals for their own amusement.
  • Laser-Guided Karma: They end up trapped in Rakaya's prison, hopefully for good this time, alongside one of the nightmares Zellin had brought to life.
  • Nightmare Weaver: Zellin can harvest nightmares and trap people inside them.
  • Sealed Evil in a Can: Rakaya. Zellin managed to evade imprisonment.
  • Shrouded in Myth: The Doctor knew Zellin as "a mythical name, way beyond this universe".
  • White Hair, Black Heart: Rakaya has white hair and turns out to be evil and, apparently, even more powerful than Zellin.


How well does it match the trope?
