History EldritchAbomination / DoctorWho

** And in the age-old cycle of AlwaysABiggerFish, the same book introduces an even ''more'' terrifying threat beyond even the Memeovore: the Swimmers. These are beings which exist within the Void between universes, and they are so unimaginably gargantuan that ''entire universes'' popped against their sides like bubbles on the side of a whale. ''Literature/FactionParadox'' would later deem Swimmers to be a type of Leviathan, entities which disturb reality by the mere fact of their existence; it also gave them a concrete size: approximately '''150 ''quadrillion'' light-years in length''' (more than 3 million times the length of a standard ''universe''). The release of the Memeovore was apparently done to prevent Swimmers from being drawn towards our universe.

* The "Not-Things" from "[[Recap/DoctorWho60thASWildBlueYonder Wild Blue Yonder]]" are an understated but ''terrifying'' example. Seemingly disembodied beings that exist at the farthest edge of the universe, they gradually became malevolent beings due to being influenced by [[HumansAreBastards the collective hatred and anger of the known universe]]. In the episode itself, they appear as copies of the Doctor and Donna, and while their physical forms have a tendency to decay into nightmarish distorted versions as soon as they stop paying attention to maintaining them, their personality imitations are ''alarmingly'' accurate. Most of the time the only reason the Doctor and Donna are able to catch on to the deception is [[spoiler:the Not-Things' extremely limited understanding of how the universe actually works (for instance, the Doctor Not-Thing's tie disappearing from the floor because "he" didn't realize that objects continue to exist even if you're not paying attention to them]]. Beyond what they tell us about their origins, we find out ''absolutely nothing'' about what they actually are or where they came from.

* The Daleks believe the Doctor is one. They [[RedBaron call him]] [[NamesToRunAwayFromReallyFast "Bringer of Darkness", "The Oncoming Storm", "The Destroyer of the Worlds" and "The Predator of the Daleks"]]; he's the only being in the universe they outright ''[[TheDreaded fear]]'' (keep in mind they were deliberately engineered to feel nothing but hate for all things non-Dalek), and [[Recap/DoctorWhoS33E1AsylumOfTheDaleks "Asylum of the Daleks"]] shows that the few Daleks that survived encounters with him were driven almost ''[[GoMadFromTheRevelation permanently catatonic]]'' by the experience.

* 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 was 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.

* [[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]].

* [[Recap/DoctorWhoS37E9ItTakesYouAway "It Takes You Away"]]: The Solitract is a rare benevolent version. It's a sentient universe, the mere existence of which caused a RealityBreakingParadox that forced the main universe to eject it before reality could begin. Contact between the Solitract and the universe threatens both of them with collapse, causing the universe to create an anti-zone (a pocket dimension) just to keep them away from each other. Despite this, the Solitract is just lonely and only lures people in so it can have company. Once the Doctor shows it that both realities are threatened by this, it willingly lets her go.

* Anti-Time essentially causes this. It is spread by the Neverpeople, people who have experienced RetGone and are left as ghosts who devour people's time. Then there is the personification of Anti-Time, [[TheDreaded Zagreus]], something which even Death fears:

* 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.

** Even a non-Dalek could make the argument the Doctor themself is a HumanoidAbomination, albeit a ([[GoodIsNotNice usually]]) benevolent one. They're an impossibly ancient being with an understanding of the universe far outside any reasonable human, they single-handedly put Gallifrey into a bizarre limbo stasis and were granted a potentially endless source of regenerations, and they have an ancient, unspoken true name. [[spoiler:[[Recap/DoctorWhoS38E10TheTimelessChildren "The Timeless Children"]] offers up even more evidence for this argument, revealing they're actually a mysterious entity from another realm, [[SingleSpecimenSpecies the only known one of their kind in this universe]], who already had an endless number of regenerations, and initial attempts to try and figure out what they might be and where they might be from didn't reveal any secrets that could be understood, aside from their ability to regenerate, which the proto-Time Lords copied and modified for themselves.]]

** [[spoiler:In the spinoff ''Series/{{Class|2016}}'', it's revealed the Angels are working with a group of humans preparing for an "arrival" involving what appears to be some sort of super-Angel, or Angel god, which seems to be ''even '''[[UpToEleven worse]]''''' than the usual kind. According [[WhatCouldHaveBeen to the series creator]] this would have involved a Weeping Angel CivilWar.]]

** In the Recap/DoctorWhoS39E4FluxChapterFourVillageOfTheAngels, the Angels are capable of lifting an entire town into a vacuous void outside of existence of regular spacetime, ''in two different time periods'', just so they could limit the movements of a singular target, and in the end [[spoiler: turn the Doctor into an angel without even touching her]].

* [[Recap/DoctorWhoS28E10LoveAndMonsters "Love & Monsters"]]: Elton's mother was killed by something called an "elemental shade" from the "Howling Halls".

* The [[Characters/DoctorWhoWeepingAngels Weeping Angels]]: impossibly fast creatures, [[NobodyHereButUsStatues indistinguishable]] from ordinary [[LivingStatue statues]] until you look away, able to transport people through time (because it's how they feed, off of all the "stolen moments"), and reproduce by projecting themselves through images, including images [[spoiler:inside a person's mind.]] On top of that, if they have enough power, they can [[spoiler:turn ordinary statues into more of their number]].

* The TARDIS itself is a ''[[GeniusLoci fully sentient]] EldritchLocation''. BiggerOnTheInside, filled with endless wonder and terror and secrets the Doctor doesn't let even their 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. The [[Franchise/DoctorWhoExpandedUniverse Expanded Universe]] says the TARDIS is a full-on EldritchAbomination, 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 that 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''']]. When a salvage crew captures it and tries to remove parts, we find out what it means to make the supreme mistake of pissing her off. Basically... ''don't''.
-->'''Eleventh Doctor:''' Don't touch a thing. The TARDIS will get huffy if you mess.

** What with Sutekh, the Flood, and the Fendahl being said to have "passed through" on its way to Earth, it's no wonder the Ice Warriors went into hibernation for millions of years before abandoning the planet altogether and Mars became a [[Main/DeathWorld dead planet]]...

* An assortment of Eldritch Abominations apparently rose from the midst of the Last Great Time War, such as the Nightmare Child, the Horde of Travesties, and the Couldhavebeen King with his armies of Meanwhiles and Never-weres.

* The Beast from [[Recap/DoctorWhoS28E8TheImpossiblePlanet "The Impossible Planet"]]/[[Recap/DoctorWhoS28E9TheSatanPit "The Satan Pit"]], so much so that ''the Doctor refuses to understand it''.

* 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 on the chaos that change has.
