History EldritchAbomination / DoctorWho

* The Trickster, part of a Pantheon, whose sole motivation is to cause chaos in the universe at large. He can alter the timeline at a whim and create an entire parallel universe as long as he has the agreement of someone and he can feed of the chaos that change has.

* There's a lot of evidence pointing towards the Time Lords being an entire ''species'' of this trope, given their incredible age and intelligence, how easily and often the very laws of reality are twisted like playthings by them (in Classic Who, they are easily capable of moving entire planets and monitor all the energy in the universe), and their inherent ability to perceive the universe in ways no other species can. Indeed, several of the conflicts between the Doctor and the Master play out a lot like battles in an endless war between two Eldritch Abominations, with the poor lesser beings caught between. DependingOnTheWriter, though. They are either this or SufficientlyAdvancedAliens.

** The fanfic ''Fanfic/TheLastGreatTimeWar'' reveals the identity and nature of these things.

[[AC:Series/DoctorWho]]

* The eponymous BigBad in [[Recap/DoctorWhoS26E3TheCurseOfFenric "The Curse of Fenric"]] is described as evil incarnate from almost the beginning of the universe, albeit [[spoiler:one without a body of its own, instead possessing others' bodies]]. One of the spinoff novels identifies Fenric as [[spoiler:Hastur the Unspeakable]] from the Franchise/CthulhuMythos.

** Even worse, The Doctor has no knowledge of the creature. He doesn't know where it came from, how long it was there, what it is, if it's the only one of its kind in the universe, or how to beat it. It's one of the very few times in the entire decades long history of the show that something like this has utterly stumped and terrified The Doctor. [[spoiler: The Hostess ultimately sacrifices herself to push the Possessed Sky out of the carriage. The Doctor remains shaken, and says the planet should be left alone suggesting that he doesn't believe it's dead.]]
-->'''Doctor:''' Let this planet keep on turning around an xtonic star. In silence.

* The [[Recap/DoctorWhoS18E4StateOfDecay Great Vampires]], who fought the early Time Lords in the war that made the entire species get sick of violence, are gargantuan winged creatures who feast on ''planets'', and can only be killed by having their heart destroyed. But they are so massive that the Time Lords 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 [[spoiler:[[ImpaledWithExtremePrejudice stabbing it with a rocket ship.]]]]

* Sutekh, Last of the Osirans, from [[Recap/DoctorWhoS13E3PyramidsOfMars "Pyramids of Mars"]]. 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 ''[[OmnicidalManiac everything]]'', his concern was very much justified.
* The Animus from [[Recap/DoctorWhoS2E5TheWebPlanet "The Web Planet"]] can generate a fungus-like substance to make an organic palace for itself, as well as possess any living creature that is in contact with gold. In the Franchise/DoctorWhoExpandedUniverse, it's actually Lloigor, one of the Great Old Ones from the Franchise/CthulhuMythos.
* The Weeping Angels: impossibly fast creatures, indistinguishable from ordinary statues until you look away, able to transport people through time (because it's how they feed, off of all the "stolen moments"), and can project themselves through images, including images [[spoiler:inside a person's mind.]]

* The House from [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]], a [[ForTheEvulz malevolent]], [[TimeAbyss ancient]] [[GeniusLoci living asteroid]] that originally existed ''outside'' the universe ([[LiesToChildren the plug hole at the bottom of the universe]]), and '''eats [=TARDISes=]'''.
* The Old God, or "Grandfather", from [[Recap/DoctorWhoS33E7TheRingsOfAkhaten "The Rings of Akhaten"]]. A creature so powerful even the Doctor is willing to consider it a god, which has been sung to for millennia (''constantly,'' with singers rotating in and out but the song never having been interrupted, ever) because if the songs cease for even a second, it will wake and devour all existence (oh, and [[spoiler:[[GeniusLoci it's the size of a planet]]]]). The parallels to [[Franchise/CthulhuMythos Azathoth]] couldn't be more blatant.
* [[Recap/DoctorWho50thASTheDayOfTheDoctor The Moment]] is one of the more understated ones and yet probably the most powerful in the series. Never mind that it's a weapon with the ability to destroy worlds, and a piece of mechanics complex enough to develop a conscience, throughout its only appearance it repeatedly and calmly punches holes in the Time Lock around the Time War. As a reminder, this is the same barrier that's strong enough to (mostly) seamlessly contain the full might of the Daleks, Time Lords, and every other EldritchAbomination they brought with them. For her part, she spends her time [[WhatTheHellHero convincing her users not to employ her for her designed purpose]] of immense destruction [[AIIsACrapShoot because she finds the whole idea just terrible]].

* The creatures in [[Recap/DoctorWhoS34E9Flatline "Flatline"]], dubbed the "Boneless" by the Doctor, two dimensional beings from outside the known universe. Among other things they drained dimensional energy from the TARDIS, and the Doctor realized that they apparently tried to learn about the three dimensional universe. He tried to find a way to communicate with them, something that proved difficult since even the TARDIS couldn't translate their language at first, and their sense of space were so alien that even the TARDIS was confused. [[HumanoidAbomination Eventually they gained three dimensional forms, heavily distorted and warped, looking like distorted reflections of human beings, their movements jerky and clumsy, constantly shifting in shape and sometimes appearing as if they couldn't keep their three dimensional form together.]] They can pull you into their 2D state as well, making ''dissecting'' you as easy as turning the page in an anatomy book; a pattern on the wall turned out to be one unfortunate character's ''entire nervous system.'' The Creator/StevenMoffat era is ''really'' good at creating these.

* Borusa and the other Time Lords Rassilon experimented on in [[Recap/NewSeriesAdventuresEnginesOfWar "Engines of War"]]. Their timelines have been retro-engineered, meaning they are in a constant state of flux between the past and possible future regenerations. They can see all possible timelines and when Borusa is in the Eye of Tantalus he is able to pull on threads of possibility to bring new timelines into being; [[spoiler:similar to Bad Wolf he is able to wipe all traces of the Daleks from the Tantalus Eye.]]

* The TARDIS itself is a ''[[GeniusLoci fully sentient]] EldritchLocation.'' BiggerOnTheInside, filled with endless wonder and terror and secrets the Doctor doesn't let even his closest friends in on, able to go anywhere in time and space - and ''very much'' alive and in more control of its movements and every single square centimeter of its as-big-as-it-wants-to-be interior than whoever is at the wheel. When a salvage crew captured it and tried to remove parts, we find out what it means to make the supreme mistake of pissing her off. Basically... ''don't.''

** The Franchise/DoctorWhoExpandedUniverse says the TARDIS is a full-on Eldritch Abomination, which considerately disguises itself to avoid reducing the passengers to gibbering wrecks. As a living shape-shifting creature, at home in extra-dimensional spaces, with a mind even the Doctor deems unfathomably alien, it's certainly a good candidate. A minor story comments on the TARDIS' mind as completely and utterly [[spoiler:'''pandimensional''']].

* The Great Intelligence, a powerful, disembodied consciousness that whispers in people's minds for years [[spoiler:or even decades]] to turn them into willing puppets, and was infrequently encountered until [[Recap/DoctorWhoS33E13TheNameOfTheDoctor "The Name of the Doctor"]] -- in which it makes an almost successful attempt to destroy the Doctor's entire life back to even before he ever left Gallifrey. [[Recap/DoctorWhoS5E5TheWebofFear Before that,]] it attempted to steal all of the Doctor's life experiences and memories and mentally revert him back to a younger age. It manifested bizarre powers and whenever it deigned to take physical form, it could BodySurf if the body it was in was damaged. The Franchise/DoctorWhoExpandedUniverse identifies the Great Intelligence as an alias of [[spoiler:[[Franchise/CthulhuMythos Yog-Sothoth]].]]

* "Ancient lights", {{Hive Queen}}s to at least part of the universe that existed before the Big Bang.
* ''[[ExactlyWhatItSaysOnTheTin The Abomination]]''. In this case a BrownNote painting and not a flesh and blood being. [[spoiler:Unfortunately, it was painted with psychically active ink, which was capable of [[ArtInitiatesLife bringing the creature depicted]] to life. [[GoneHorriblyRight Oops]].]]

The 2011 episode [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]] has the mind and essence of the TARDIS trapped inside a humanoid female body for a while, and it is shown to be kind and caring, and feels nothing but love for the Doctor.

** If they weren't this initially, then [[spoiler:they ''definitely'' became this during the Last Great Time War]], given the Doctor's description and the events of [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]].

* An assortment of Eldritch Abominations apparently rose from the midst of the Last Great Time War, such as the Skaro Degradations, the Nightmare Child, the Horde of Travesties, and the Couldhavebeen King with his armies of Meanwhiles and Never-weres. [[spoiler:The Time Lock around the War is there, in part, to stop these things from ever getting out.]]

* The eponymous creature in [[Recap/DoctorWhoS15E3ImageOfTheFendahl "Image of the Fendahl"]]; everyone who saw it died of fright, and that was only a crippled ghost of its true self 12 million years dead, which had been manipulating human lineages for millennia to ensure its release. In the Franchise/DoctorWhoExpandedUniverse, the Time Lords deliberately created the Fendahl Predator, a malign void which could reach across time and space to feed on the stuff of thought and hungered to [[OmnicidalManiac devour all eternity]], from the Big Bang to the end of time. Those who looked at it saw an endless procession of grotesque images, as their mind struggled to comprehend the incomprehensible. [[TooDumbToLive And then the Time Lords released it to use for warfare]] -- only to find it already dead at the hands of an even ''worse'' abomination -- the Memeovore, the Devourer of Concept.\\\
Not everyone who saw the Fendahl was lucky enough to die of fright. The Core transformed some of them into Fendahleen (the other components that, together with the Core, make up the Fendahl). The leader of the cultists who completed the process of creating the Core had worse luck than that. He was still alive, still human, and seeming still sane... but what he saw when he looked into the eyes of the Fendahl caused him to request the means to kill himself. How bad it was is evidenced by the Doctor giving him those means.
