History EldritchAbomination / WesternAnimation

* ''WesternAnimation/CourageTheCowardlyDog'' has a few. Horst’s Box Demon is an inexplicably BiggerOnTheInside chest monster. The episode "Muted Muriel" features a destructive giant starfish as the result of a curse. And The Spirit of the Harvest Moon is a [[MindOverMatter telekinetic]] DemonHead that defies comprehension, save for its desire for Eustace to grow something.

** In the ''WesternAnimation/SupermanTheAnimatedSeries'' episode "Recap/SupermanTheAnimatedSeriesS3E10Unity Unity]]", the titular entity is a HiveMind alien blob thing that uses a creepy preacher as its primary avatar, turning [[spoiler:Smallville]] into a TownWithADarkSecret and nearly absorbing all of the townsfolk into itself.
*** In the comics, Ian Karkull is a guy with shadow powers, but in this, it's like the writers didn't know if they wanted Cthulhu or Satan and so ''combined them''. A common hood gets his hand on a tablet and reads it aloud. ''Bad'' idea. He becomes the host to a shadowy tentacled ''something'' that wants to create HellOnEarth and basically overwrites the Daily Planet with his own unreality, everyone caught within, Lois and Jimmy included, becoming possessed and transformed by the demonic creatures that live there. There's a seemingly bottomless pit in the center. In the end, Superman has to chase the dropped tablet (ComicBook/DoctorFate needs the original tablet to undo it all) down this pit, and it turns that if you go far enough, farther than the eye can see from the surface, the pit ''does'' have a bottom. The bottom ''has a mouth.'' The bottom is also '''rising.'''

-->'''Yivo''': [[NeveryMyFault Your universe dresses provocatively]].

** Yivo from "[[Recap/FuturamaM2TheBeastWithABillionBacks The Beast with a Billion Backs]]", a genderless (it prefers to be referred as "shklee" or "shkler"/"shklim") GeniusLoci with one eye and thousands of tentacles the size of a very large planet that [[DidYouJustRomanceCthulhu attempts to romance with the entire universe]]. However, Yivo is a ''friendly'' cosmic horror that really only seeks to be in a relationship with somebody (or in this case, everybody).

** The Lich, the closest thing the show has to a BigBad. He's a monstrous necromancer/''thing'' that looks like a rotting, horned corpse in it's natural state and can possess mortals, wearing their corpses like suits. [[TimeAbyss He's existed for about a thousand years and doesn't appear to age in any manner]]. He is also an OmnicidalManiac who claims to be the personification of death and cannot feel empathy, seeking to destroy all life. What's most unsettling is that it's stongly implied that [[spoiler:he WasOnceAMan. Specifically, he was apparently a semi-normal person or creature who was hit by a magically enhanced warhead from the Great Mushroom War, which transformed him into the Lich.]] The Lich may very well have existed before even nothingness... but even if he didn't, he can provide some images of some horrible, horrific abominations from that not-time.

** The strange, shapeshifting, dimension-hopping, blue monster from the flashback episode "Joshua and Margaret Investigations". [[spoiler:It is revealed that [[MisterSeahorse Jake was born from a lump on Joshua's head after he was bitten by this thing.]] This explains where Jake's powers came from]] and this likely means that he is an [[AnimalisticAbomination abomination himself]] and doesn't know it.
** [[spoiler:In "Orgalorg", the titular creature is an Eldritch Abomination who was banished to Earth, possibly prior to the Great Mushroom War, and was compressed into a harmless form-a form we know as Gunter. During The Lich's speech about the "monsters" before time, Orgalorg can be seem among them, indicating that he is older than the universe.]]
** [[spoiler: The Catalyst Comet itself is revealed to be one in "The Comet", although it wasn't malevolent.]]
** The being known as GOLB that cameo'd in a few episodes also counts, as he appears as a cosmic destroyer that comes around every once in a while, striking fear into even [[RealityWarper Magic Man]]. GOLB appears to have strange geometric shapes floating around him, and those he kills [[spoiler:([[FreudianExcuse Magic Man's wife]] among them) are either unaffected by magic, or erased from existence entirely.]] "Whispers" heavily hints that [[spoiler:he may in fact be the series' GreaterScopeVillain, as [[BigBad the Lich himself]] describes himself as "the last scholar of GOLB"]]. In the GrandFinale, [[spoiler: GOLB becomes the ultimate threat to the Land of Ooo. He is revealed to be the very embodiment of chaos itself, and was shown creating a lesser EldritchAbomination out of an entire army just by releasing his BreathWeapon. He can also "digest" people by breaking them down to their original forms.]]

* ''WesternAnimation/{{Centaurworld}}'' has ([[NotMakingThisUpDisclaimer yes, really]]) [[spoiler: the Nowhere King, a strange, gigantic monster resembling a cross between a deer and a wasp made of black slime. It's not clear ''what'' exactly it is yet, but it's rather disturbingly implied to have [[WasOnceAMan started off a normal centaur]] and is implied by it's VillainSong to desire the complete annihilation of all life on both Horse's homeland and Centaurworld]].
* ''WesternAnimation/CourageTheCowardlyDog'' has a few. Horst’s Box Demon is an inexplicably BiggerOnTheInside chest monster. The episode “Muted Muriel” features a destructive giant starfish as the result of a curse. And The Spirit of the Harvest Moon is a [[MindOverMatter telekinetic]] DemonHead that defies comprehension, save for its desire for Eustace to grow something.
* Franchise/{{DCAU}}:
** ''WesternAnimation/SupermanTheAnimatedSeries'' had as a one-time threat a HiveMind alien blob thing that called itself "Unity". Using a creepy preacher as its primary avatar, it turned [[spoiler:Smallville]] into a TownWithADarkSecret and nearly absorbed all the townsfolk into itself.

** In a two part ''WesternAnimation/JusticeLeague'' episode "The Terror Beyond", Comicbook/{{Superman}} and Co. go fight [[LawyerFriendlyCameo Ichthultu]]. A giant alien monstrosity not bound by time or space going up against a group of superheroes in a work that sits firmly on the Idealistic side of the SlidingScaleOfIdealismVersusCynicism? The [[DidYouJustPunchOutCthulhu beatdown]] was the source of much awesomeness. For extra fun, said Abomination is voiced by Music/RobZombie.
* ''WesternAnimation/DextersLaboratory'':
** The interdimensional beast "Jojo" in "Mandarker". He apparently helped Mandark write the book ''The Magic of Science by Mandark and Jojo'', but when Mandark summons him as part of a science fair project, he goes berserk and tries to eat Dee Dee.
* In its planning stages, ''WesternAnimation/TheEmperorsNewGroove'' originally had VainSorceress Yzma summon a force of darkness, called Supai, to [[TheNightThatNeverEnds blot out the sun and plunge the entire world into eternal night]].
* The BigBad of ''WesternAnimation/Epic1984'', the Spirit of Evil is this; even when its physical form is defeated its disembodied spirit rises to the sky in the form of an angry face, from where it continues to harass the heroes.

** Yivo from the second movie "The Beast with a Billion Backs", a genderless (it prefers to be referred as "shklee" or "shkler"[=/=]"shklim") GeniusLoci with one eye and thousands of tentacles the size of a very large planet that [[DidYouJustRomanceCthulhu attempts to romance with the entire universe]]. However, Yivo is a ''friendly'' cosmic horror that really only seeks to be in a relationship with somebody (or in this case, everybody).

** The title SpaceWhale from "Mobius Dick" could certainly count. It is an enormous leviathan that is actually native to the fourth dimension, but "breaches" into ours because it breathes the vacuum of space. It also has a Mobius colon and feeds on the obsessions of the space captains who hunt it, slowly absorbing them into its own mass.

** An [[EasterEgg easter egg]] in the episode "Irrational Treasure" lists on the top-secret Northwest Cover-Up document that there is an enormous, evil, time-devouring baby from another dimension [[SealedEvilInACan that is frozen in an Antarctic glacier]]. "The Time Traveler's Pig" reveals that the "Time Baby," as its mortal supplicants dub it, is eventually released and conquers the world... or at least establishes the TimePolice.
** Bill Cipher, a [[SinisterGeometry pyramid-shaped]], [[RealityWarper reality warping]] demon who invades people's dreams. "I'LL BE WATCHING YOU..."
** We later get to meet Bill's friends, who are also Eldritch Abominations: 8-Ball, Kryptos, [[SpeakOfTheDevil The Being Whose Name Must Never Be Said]][[note]]Aww, what the heck? It's Xanthar.[[/note]], Teeth, Keyhole, Hectorgon, Amorphous Shape, Pyronica, Pacifier, and the eye bats[[note]][[MyFriendsAndZoidberg Dubbed by Bill as "these guys".]][[/note]].

* Short-lived (only 13 episodes long) 80's Creator/{{Hasbro}} series ''{{WesternAnimation/Inhumanoids}}'' revolved around the heroic "Earth Corps" fighting against ancient, {{kaiju}}-like horrors from the center of the Earth. The three main antagonists were Metlar (giant mineral-based demon who throws globs of molten rock/iron at his foes), D'Compose (rotting zombie dinosaur who could revive the dead and turn the living into decaying zombie slaves with a touch) and Tendril (Cthulhu-like [[WhenTreesAttack plant-monster]]). Others appeared in several episodes, like Gagoyle and Ssslither, whilst recurring foe Nightcrawler was a HumanoidAbomination created by D'Compose from the corpse of a human enemy.
* An episode of ''WesternAnimation/MovilleMysteries'' revealed the school janitor was a former AdventurerArchaeologist who had one these (all we see of it are red tentacles) [[SealedInsideAPersonShapedCan sealed]] in [[EvilHand his big toe]].

** Discord is an embodiment of chaos with [[MixAndMatchCritter parts from many animals]] who dwells in an EldritchLocation. His powers are completely uncontrollable by anyone less chaotic than him, and have once opened a portal to a live-action puppet dimension. His powers also allow him to, among other things: [[RealityWarper break the laws of reality]], MindRape the protagonists, bring villains back from the dead, and easily NoSell King Sombra's attacks.
** There's also the Windigos, otherworldly creatures that feed on hatred that are apparently unkillable, and are so mysterious that many ponies thought they didn't even exist. The inhabitants of Equestria are essentially held hostage by them because the second they stop being nice to each other, the Windigos come back into existence and [[TheEndOfTheWorldAsWeKnowIt freeze the land.]] They greatly resemble Ithaqua, a beast that came from the mind of Creator/HPLovecraft himself.
** The Tatzlwurm is a bizarre SandWorm-esque creature that lives underneath a [[ToweringFlower massive flower]] at the edge of Equestria. Even Discord has no idea what it is, and when it sneezed on him [[spoiler:he got sick. Discord, the RealityWarper who knows things he never had the opportunity to learn, is completely shocked by it.]]

** The Preeminent, the DimensionLord [[spoiler:([[GeniusLoci and actual dimension]])]] of the Cursed Realm whose goal is to curse all realms, is a tentacled {{Oculothorax}} who [[spoiler:appears as a {{Kaiju}} in the finale and uses ghost-ified houses and buildings to enhance her physical form, giving herself limbs.]]
* ''WesternAnimation/{{Pibby}}'': The trailer sets up the series' main antagonist: a formless, [[OminousVisualGlitch glitchy]] mass that invades various worlds and relentlessly consumes anything it can touch. If someone gets [[TheAssimilator assimilated]] into it, they become a part of it – either their face appears on its body or they become one of its minions, sporting an eerie grin and glitch-marred facial features in both cases. (Several shots depict it with a lower FPS than anything else in the scene to further indicate how alien it is.)
* Among others, ''WesternAnimation/TheRealGhostbusters'' took on Cthulhu in "The Collect Call of Cthulhu". According to Egon Spengler, the infamous elder god "makes [[Film/Ghostbusters1984 Gozer the Gozerian]] look like Little Mary Sunshine." Of course, [[DidYouJustPunchOutCthulhu Punching out Cthulhu]] is pretty much their job description.
** There was also the unnamed Old One from the subsequent episode [[http://ghostbusters.wikia.com/wiki/Russian_About Russian About]], complete with evil {{Cult}} and TomeOfEldritchLore.
* The demon that [[BigBad Mok]] wants to summon in ''WesternAnimation/RockAndRule'' lacks a fully defined, stable form, has immense power, and its actions are more akin to an all-consuming supernatural force of destruction than those of a recognizably sentient being.
* In ''WesternAnimation/SabrinaTheAnimatedSeries'' when Sabrina, Harvey and Salem are trapped inside Harvey's comic book world, they encounter an entity known as the Dreaded Dysphilia. It appears as a flying blob of fungus that erases everything in its path forever, and Harvey's negative self-esteem makes it bigger. That's right -- a monster that is powered by the negative self-esteem of a ''teenager''. What's more is that it's completely alien to the comic book world -- Harvey didn't even create it.
* In the backstory of ''WesternAnimation/SamuraiJack'', the gods, Odin, Vishnu and Ra, hunted and defeated Evil itself, a black mass of pure ''nothing''. A single fragment survived and fell to Earth and eventually becoming another eldritch horror known as [[BigBad Aku]], a vaguely HumanoidAbomination of [[MadeOfEvil pure evil]] with [[{{Shapeshifter}} shapeshifting powers]] and immunity against all conventional weaponry. The only thing that can truly hurt [[spoiler:and kill]] him is the [[CoolSword divine sword]] that's wielded by [[TheHero the titular hero]].
* The Evil Entity of ''WesternAnimation/ScoobyDooMysteryIncorporated'' is an evil annunaki, which are extradimensional beings that usually communicate by possessing animals. Nibiru spends most of the series [[SealedEvilInACan sealed in a coffin]], but still manipulates the creation of mystery solving groups and either attracts or creates the various crooks in costumes, as well as [[TheCorruption stealing and imprisoning the best parts]] of people that live in Crystal Cove. When released, it [[HellOnEarth unleashes hell and animal headed minions on the town]] and [[ToServeMan starts eating the residents]], swearing to [[OmnicidalManiac eat entire galaxies and eventually the universe]]. Yes, the offspring of Satan and Cthulhu made an appearance on a Scooby-Doo show.

* ''WesternAnimation/StevenUniverse'' has The Cluster, a fusion of millions of Gem shards, created by the Diamonds to be a superweapon that would destroy Earth. Its projection appears to be an enormous mass of faces and hands, and it [[VoiceOfTheLegion speaks in millions of voices at once.]] Their voices entering Steven's mind was enough to painfully overwhelm him. Its true form was revealed in the official artbook as a massive, horrific creature with [[TooManyMouths countless mouths]] and [[EyesDoNotBelongThere eyes]], serving as this page's image.

* ''WesternAnimation/TangledTheSeries'' has the true BigBad, Zhan Tiri. [[spoiler: It's indicated she [[WasOnceAMan was human]] long ago, and spending millennia in the [[EldritchLocation Lost Realm]] turned her into a huge demonic monstrosity with a vaguely goat-like head, [[GlowingEyesOfDoom glowing eyes]], and a lower half full of tentacles. She also has [[VoluntaryShapeshifting shapeshifting abilities]] and can turn into anything, including a blizzard that nearly wiped out the entire kingdom of Corona. Even while trapped in her Enchanted Girl form, she could still invade people's dreams and, as shown in "Once a Handmaiden...", can apparently send people disturbing visions when they touch her.]]
* The final episode of ''WesternAnimation/TenkoAndTheGuardiansOfTheMagic'' had a man try to release a soul-devouring MadeOfEvil monstrosity that he claimed was the source of every culture's apocalypse myths, with a testament to its power being the destruction of {{Atlantis}}.

** The Elders Gods, a race of cold, alien, and evil intelligences that exist in the non-spacetime of swirling anti-matter "outside" our universe dwarfing even Unicron in terms of power, their limitless abilities are kept in check only by their inscrutable motivations and indifference to the affairs of lesser beings that exist in what we so arrogantly call "reality". Also H.P. Lovercraft once encountered them which inspired him to make them the basis of his novels.

** There's Hytherion also known as the "Beast of Time", who is a hyper-dimensional creature of immense power and destructive potential, capable of traveling freely throughout the Multiverse. Composed of interdimensional matter, Hytherion's feeds on time itself, is known to have devoured entire universes,(apparently it's function is to consume weakened and damaged universes, preventing their chaos from spreading further into the multiverse) and ot is normally invisible and intangible to lower-dimensional beings snd it is prophesied that a version of Megatron will lead the creature to destroy Earth one day.

* ''WesternAnimation/TheTrapDoor'' is full of these things (including the main character's employer). Some of them really quite nightmarish. [[WhatDoYouMeanItsForKids It's an 80's British claymation kids' show.]]
* ''WesternAnimation/WanderOverYonder'' has The Black Cube Of Darkness. Essentially it is ExactlyWhatItSaysOnTheTin. A [[SinisterGeometry floating black cube]] that speaks in Latin gibberish and is capable of sucking out your soul. His first appearance gives no explanation for its existence and none of the characters even address it directly, which makes it all the more hilarious. The Season 2 episode "The Black Cube" goes into much more detail about him and his life.
** A giant space demon known as Tormato appears very briefly in the episode "The Funk", where it proceeds to skewer several planets on a spike and barbecue them.

* An episode of ''WesternAnimation/TheWildThornberrys'' set in Africa had Eliza and Darwin venture into a forbidden patch of the jungle where a demon, monster, or something even worse supposedly dwelled. The seemingly supernatural events that occur throughout the episode ''could'' be regarded as Eliza simply hallucinating from panic and fear... [[RealAfterAll until the very end]].
* ''WesternAnimation/XMenTheAnimatedSeries'' has the Spirit Drinker. (It exists in [[ComicBook/XMen the comics]], but the animated version fits the bill better.[[note]]The comic version was a BigLippedAlligatorMoment where a guy summoned it to attack Lilandra, who was 'ported away by Nightcrawler, leaving it to accidentally take out another {{Mook}} and then vanish as it can only take one soul per summon. Replace it with one more grunt with a blaster and not much changes. It appears once more in a everyone-sees-their-worst-fears situation; naturally, the summoner's worst fear is his pet turning on him.[[/note]]) Trapped in a spaceship that was then launched into deep space was the only way the Shi'ar could get rid of it, and when the villains of the week tried to get their hands on the mysterious cargo, they, and the X-Men, find themselves up against a terrifying and constantly re-forming EnergyBeing with three tongue-tentacles that will steal your soul (causing the ''lovely'' image of the soul's owner appearing in its shifting not-flesh begging you for either help or to run and save yourself.) When Jean tried to read its mind, what she saw was so horrible that she was left in actual, physical agony because its mind was just ''that'' repellent (you could've taken it as a simple predatory animal until then, but no -- ItCanThink, and you don't want to know ''what'' it thinks. Also, it's quite capable of strategizing.) It's as solid as it wants to be, can melt through walls, need only get a brief tongue-hold to [[YourSoulIsMine earn its name]], and gains strength with each new victim -- if it had gotten out of the tunnels and into the city proper, it would've been unstoppable. The list of things that scares ''Lady Deathstrike'' is ''very'' short, but this earned a place.

* ''WesternAnimation/{{Centaurworld}}'' has ([[NotMakingThisUpDisclaimer yes, really]]) [[spoiler: the Nowhere King, a strange, gigantic monster resembling a cross between a deer and a wasp made of black slime. It's not clear ''what'' exactly it is yet, but it's rather disturbingly implied to have [[WasOnceAMan started off a normal centaur]] and is implied by it's VillainSong to desire the complete annihilation of all life on both Horse's homeland and Centaurworld]].

* ''WesternAnimation/{{Centaurworld}}'' has ([[NotMakingThisUpDisclaimer yes, really]]) [[spoiler: the Nowhere King, a strange, gigantic monster resembling a cross between a deer and a wasp made of black slime. It's not clear ''what'' exactly it is yet, but it's rather disturbingly implied to be [[WasOnceAMan formerly human]] and is implied by it's VillainSong to desire the eradication of all life on both Horse's homeland and Centaurworld]].

--> "Before there was time... before there was anything... there was nothing. [[TheDarkTimes And before there was nothing...]] there were ''monsters''."

* ''WesternAnimation/{{Final Space}}'':

* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy''

* ''MyLittlePonyFriendshipIsMagic'':

* Among others, ''WesternAnimation/TheRealGhostbusters'' took on Cthulhu in "The Collect Call of Cthulhu". According to Egon Spengler, the infamous elder god "makes [[Film/{{Ghostbusters 1984}} Gozer the Gozerian]] look like Little Mary Sunshine." Of course, [[DidYouJustPunchOutCthulhu Punching out Cthulhu]] is pretty much their job description.

*** We later get to meet Bill's friends, who are also Eldritch Abominations: 8-Ball, Kryptos, [[SpeakOfTheDevil The Being Whose Name Must Never Be Said]][[note]]Aww, what the heck? It's Xanthar.[[/note]], Teeth, Keyhole, Hectorgon, Amorphous Shape, Pyronica, Pacifier, and the eye bats[[note]][[MyFriendsAndZoidberg Dubbed by Bill as "these guys".]][[/note]].
*** How bad? ''Summoning [[SummonBiggerFish the Time Baby]] back to the present'' is seen as [[GodzillaThreshold an acceptable way]] to try and stop him. [[spoiler: Bill utterly vaporizes it in seconds. Then things get worse]].

** Diagon. It's held behind the same seal as Lucubra, but is ''much'' worse (Gwen says compared to Diagon, Lucubra is an ''insect!''). In the next episode, they're actually shown the Diagon, and while the audience doesn't see it ([[TrailersAlwaysSpoil though commercials very clearly show him]]), Gwen and Kevin react to seeing him as if they were ''in pain''. [[http://ben10.wikia.com/wiki/Diagon Just take a look.]] He comes from another dimension, is referred to as an "Old One" by Charmcaster, and has enough power to match and defeat a powered up Way Big (one of Ben's most powerful aliens, if not THE most powerful).

** Mooncake is a cute flying green ball that appeared after John Goodspeed closed the gap leading to Final Space.
** The Arachnitects are giant mechanical spiders that created the universe.

** Invictus is an ancient, out of nowhere evil that is responsible for the distortion of the Titans. It takes the form of an incorporeal demonic head and is described as a creature of pure darkness.
** Werthrent is a terrifying, serpentine deity from another dimension who was worshiped on Ash's home planet. People who are consumed by it are [[AndIMustScream kept alive]] in a pocket dimension in its stomach, where it feeds on their wellness.

* In the backstory of ''WesternAnimation/SamuraiJack'', the gods, Odin, Vishnu and Ra, hunted and defeated Evil itself, a black mass of pure ''nothing''. A single fragment survived and fell to Earth and eventually becoming [[BigBad Aku]]. However, Aku avoids this trope. He has an understandable nature, sapience and humanoid form, since evil is completely understandable to humans.

* In ''MyLittlePonyFriendshipIsMagic'', Discord qualifies. He is an embodiment of chaos with [[MixAndMatchCritter parts from many animals]]. While this may not be enough on its own, it is worth noting that he dwells in an EldritchLocation, and his powers are completely uncontrollable by anyone less chaotic than him. His powers also allow him to, among other things: [[RealityWarper break the laws of reality]], MindRape the protagonists, bring villains back from the dead, and easily NoSell King Sombra's attacks.

** Lucubra, the main antagonist of the episode "The Creature From Beyond" [[spoiler:and one of the breed of monstrous minions to the BigBad of the season, Diagon]]. This extra-dimensional horror boasts SuperStrength, NighInvulnerability, FrickinLaserBeams, and the power to devour a person's thoughts with MindControl as a bonus.

** [[spoiler:In "Orgalorg", the titular creature is an Eldritch Abomination who was banished to Earth, possibly prior to the Great Mushroom War, and was compressed into a harmless form-a form we know as Gunter.
