{{Eldritch Abomination}}s in FanFiction.

[[foldercontrol]]

[[folder: ''Western Animation/Avatar The Last Airbender'' ]]

* ''FanFic/TheWorldWithoutTheWar'' has [[spoiler: the Four Elemental Beasts, who were created by the World Spirit before it took notice of humanity's existence. Their "logic" is similar to that of the Avatar, and when the Phoenix, the Beast of Fire, [[SealedEvilInACan escapes]], the other three Beasts will awaken, they would destroy civilization. Because that's the only way they can communicate with humans]].
* In the AlternateUniverseFic ''FanFic/{{Embers}}'', quite a few of the more dangerous spirits are either this or an AnimalisticAbomination.

[[/folder]]

[[folder: ''Manga/Bleach'' ]]

* ''FanFic/HammeredDown'' portrays the Vasto Lorde-class Espada as AnthropomorphicPersonification(s).

[[/folder]]

[[folder: ''Western Animation/Codename Kids Next Door'' ]]

* Invoked/parodied in ''[[http://www.fanfiction.net/s/4657412/1/Operation_There_Is_No_Operation Operation: There Is No Operation]]'' where we meet the Galactic Kids Next Door, some of which are eldritch abominations with unpronounceable names. Since they are minors, they only induce temporary insanity in other species who see them and only with specific intervals, so as long as you remember to blink at the right time, you are fine. [[MarsNeedsWomen Oh, and one of them wants to date Nigel Uno.]]

[[/folder]]

[[folder: Cross Over ]]

* ''Fanfic/AeonNatumEngel'' and ''Fanfic/AeonEntelechyEvangelion'' mix ''Anime/NeonGenesisEvangelion'' with ''TabletopGame/CthulhuTech'' and ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]'', while ''Fanfic/ThousandShinji'' mixes it with ''TabletopGame/{{Warhammer 40000}}''. Let's just say much unpleasantness follows.
* ''[[http://www.fanfiction.net/s/6260492/1/Happy_Families_Are_All_Alike Happy Families Are All Alike]]'' has mentioned unliving beings from beyond the veil of death (which Orochimaru apparently enjoys killing) and the Kyuubi has displayed unnerving powers, which in the 7th chapter escalated to full-on mind-shattering EldritchAbomination status.
* ''FanFic/PersonalityConflicts'' depicts [[EnemyWithin the Green Ranger]] and Nyghtmayr as this.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic''/''Series/DoctorWho'' crossover ''FanFic/TimeLordsAndTerror'', The Smooze, the infamous BlobMonster from the [[WesternAnimation/MyLittlePonyTheMovie G1 theatrical movie]], is re-imagined as the SMz, an [[OmnicidalManiac omnicidal]] cloud of [[EnergyBeings psychokinetic energy]] whose voice alone is enough to incapacitate mortals with its innate hideousness, and who will be satisfied with nothing short of absorbing all the psychokinetic energy (AKA 'life energy') in not just the universe, but the ''multiverse''. This thing is essentially an actively malevolent ApocalypseHow/ClassZ Event! The only way the non-Time Lord protagonists are able to withstand ''seeing'' the monstrosity with sanity intact is with the help of [[ReversePolarity inverted perception filters]]. It doesn't help that the author can convincingly write in the CosmicHorrorStory style, with in-depth descriptions of the alien and often contradictory aspects of the abomination, nor that it was deliberately written to channel [[VideoGame/MassEffect1 Sovereign]].
* The ''Manga/RanmaOneHalf''/''Anime/SailorMoon'' fic ''FanFIc/TheDarkLordsOfNerima'' has something called Unit Zero. We know next to nothing about it, except that it has enormous power and if given the chance, will attack Sailor Moon via some unknown means.

[[/folder]]

[[folder: ''Franchise/Digimon'' ]]

* The [[ArcVillain Nightmare virus]] from the ''FanFic/TamersForeverSeries'', which later evolves into a HumanoidAbomination, once it assumes Takato's Image.

[[/folder]]

[[folder: ''Video Game/Free Space'' ]]

* The fan mod ''VideoGame/BluePlanet'' applies this to the Shivans (who were merely StarfishAliens in the canon games... as far as anyone knows). Shivans in the BP-verse are [[spoiler:implied to be tied to the very fabric of reality, and are eternal, infinite, and (as a whole) invincible.]] They are also described as being "as far above humanity as humanity is above a protein chain". Much of exactly ''what'' they are is obscured through some very strange TechnoBabble, for example, they were described as not being "made" but rather "calculated". Being in contact for a brief few minutes with the Shivan consciousness contains a real risk of the human going completely insane from the experience, and several times Ken deliberately cuts off contact to certain parts of it to protect the player's mental stability.

[[/folder]]

[[folder: ''Franchise/Harry Potter'' ]]

* ''[[http://www.fanfiction.net/s/9172846/1/Deathly-Hallowed Deathly Hallowed]]'' portrays [[TheGrimReaper Death]] as this. Lily summons it to [[DealWithTheDevil make a bargain with it]]. She'll return it's cloak in exchange for Death protecting her son. However, even after using a ritual to allow it a form, it's described as having "Far too many hands, too many eyes, too many mouths" and can only seem to speak in a almost [[MindRape mind-raping]] form of telepathy or BlackSpeech.
** Perhaps worse is all the Eldritch Abominations that seem to be after both Harry and Death.

[[/folder]]

[[folder: ''Western Animation/Jackie Chan Adventures'' ]]

* ''FanFic/{{Webwork}}'' has the entities that [[CosmicChessGame sit in control]] of the BalanceBetweenGoodAndEvil, referred to only as IT (evil) and OTHER (good). They've apparently existed since at least the dawn of time (or possibly even earlier), are never properly described, and are so powerful that just being in IT's presence ''terrifies'' Tarakudo.

[[/folder]]

[[folder: ''Western Animation/Kim Possible'' ]]

* ''FanFic/BloodBondBloodOmenSeries'' culminates in [[spoiler:a fight against [[NamesToRunAwayFromReallyFast the Unshaper]] that is using the Go family as its avatars so it can swallow the Earth whole]].

[[/folder]]

[[folder: ''Franchise/Kingdom Hearts'' ]]

* ''FanFic/KingdomHeartsIIITheHeartsGreatestWeapon'' has [[spoiler:Darkness, a massive creature who spawned the Heartless and, by extension, the Nobodies, and took over Kingdom Hearts itself.]]
* ''[[https://www.fanfiction.net/s/5740264/1/Fill-the-Moon Fill the Moon]]'' has Hollowmoon, a colossal creature that is the AnthropomorphicPersonification of the darkness within Kingdom Hearts. It's implied that it [[DrivenToSuicide drove the protagonist to suicide]].
** There's also the [[spoiler:AnthropomorphicPersonification of Kingdom Hearts. Hollowmoon is her brother, and they're implied to have an [[BrotherSisterIncest incestuous relationship]].]]

[[/folder]]

[[folder: ''Franchise/The Legend Of Zelda'' ]]

* In ''FanFic/LegendOfZeldaSacredReliquary'', one stalks the streets of Hyrule Castle Town at night. [[spoiler: Its true form is apparently Dark Link.]]
* In the ''FanFic/BoundDestiniesTrilogy'', [[VideoGame/TheLegendOfZeldaMajorasMask Majora]] is even more eldritch than in canon, subjecting Link to TheCorruption in ''Blood and Spirit''.
** WordOfGod establishes Majora as the Terminian counterpart to [[GodOfEvil Demise]].

[[/folder]]

[[folder: ''Franchise/Les Miserables'' ]]

* The expanded FanVerse of ''FanFic/ParisBurning'' includes several of these, the most prominent (at the moment) of which resides under the Antarctic ice and seems to be implementing an AssimilationPlot.
** Others include the broken giant that "starts" in Arizona, the Antarctic ice's sister that has a lock on pretty much all of Canada, things moving underground in the east, Aberdeen's father, and the sighing mountains.
*** They all hate Antarctica because the Thing Under the Ice is the runt of the litter.

[[/folder]]

[[folder: ''Franchise/Mass Effect'' ]]

* The Reapers were this already, but in ''[[http://www.fanfiction.net/s/5339492/1/Spectre Spectre]]'' Sovereign has taken it to new heights, all but [[MindRape mind raping]] Shepard on more than one occasion.

[[/folder]]

[[folder: ''Western Animation/My Little Pony Friendship Is Magic'' ]]

* The original VideoGame/GarrysMod Applejack model was so [[UncannyValley freaky]] that it was reinvented as [[http://www.youtube.com/watch?v=mL5-8R6Kklg Eppaljeck]], in the style of other [=GMod=] abominations (see below).
** Oh, and by the way: [[spoiler:''[[OhCrap It killed those abominations.]]'']]
* In the early days of the fandom Celestia and Luna were [[AlternativeCharacterInterpretation interpreted]] as benevolent Abominations instead of "mere" {{Physical God}}desses, due to their [[ReallySevenHundredYearsOld incredible age]] (Luna is more frustrated that being imprisoned in the moon for a thousand years means she's a FishOutOfTemporalWater, rather than from ''[[AndIMustScream being imprisoned for a thousand years]]''), almost unmatched power, NonStandardCharacterDesign, and being [[GodEmperor worshiped as deities]] by their subjects with a combination of unquestioning obedience and paralyzing fear. However, after season 2 and the reveal of Discord (see below) that interpretation fell well into the minority.
** ''[[http://www.equestriadaily.com/2011/05/story-merely-mare.html Merely a Mare]]'' has Luna casually mention that she and her sister are more than ''four hundred '''million''''' years old, spending most of that time playing in the glaciers and lava flows of the planet respectively, and the mane six are continually reminded that the two are very much Other.
* [[CloudCuckooLander Pinkie]] [[GenkiGirl Pie]] is sometimes written as an [[HumanoidAbomination Equine Abomination]]. There is a disturbingly high amount of supporting evidence, what with her tendency to [[OffscreenTeleportation appear wherever she wants whenever she wants]] (much to the horror of Rainbow Dash and Cranky Doodle), including in places that couldn't possibly be large enough, her mastery of {{Hammerspace}}, and her apparent MediumAwareness, things which are explicitly noted in the show as being weird and unexplainable. Fortunately, as [[ForHappiness the Element of Laughter]] Pinkie Pie is very much a benevolent "Abomination".
* In ''[[http://www.fimfiction.net/story/1451/6/The-Monster-Mash/Twilight-Sparkle%3A-The-Case-of-Wild-Clover-the-Warder Twilight Sparkle: The Case of Wild Clover]]'', the eldritch abomination [[spoiler:is you]].
* [[GodOfEvil Discord]] is frequently written (most famously in the ''FanFic/PonyPOVSeries'') as [[AnthropomorphicPersonification the personification of chaos itself]], whose [[RealityWarper near-unlimited power]] stems from him being so fundamentally opposed to ''reality itself'' that they reject each other, allowing him to make pretzels out of physics, and is [[EvilCannotComprehendGood completely incapable of comprehending]] things that are remotely orderly or sane.
* Speaking of the ''FanFic/PonyPOVSeries'', it also has [[spoiler:Discord's parents]] Entropy and Havoc, respectively the {{Anthropomorphic Personification}}s of Heat Death and Mass Hysteria. The former is so massive that her just ''rising'' from the ocean of chaos she calls home creates waves that could drown ''continents'', and if she merely ''says'' someone doesn't exist (at least, in her own realm), then they ''never did''. The latter is described as every fear that ever has, does, or ever will exist personified, and is so horrific to behold that just ''looking'' at him will leave a mortal pony incapable of sleeping for the rest of their days at ''best''. Entropy erasing Havoc from existence, then him ''willing himself back into it'' is equal to one member of a bickering couple shoving the other. Both have severe BlueAndOrangeMorality, Entropy viewing nothing as of value (even her own children) while Havoc's is described as, while valid, so alien its impossible for the personification of ''Wisdom'' to put it in words a mortal can comprehend. Meanwhile, [[spoiler:Celestia's parents]] are just as massive, powerful, and [[YouCannotGraspTheTrueForm indescribable]], but are among the kindest beings in existence, even stepping in and [[spoiler:saving the pony world from Havoc and Entropy's wrath when they were accidentally enraged]] and being in the presence of either is described as reassuring and pleasant. The Father of All Alicorns is stated to ''[[GeniusLoci be]]'' Pony Heaven. All four Elders are multiversal singularities, meaning every alternate version of them is merely another part of the same being.
** Discord's repeatedly cameoed cousin Ponythulu, who seems to be this trope played for laughs, as he's yet to do anything remotely evil, and actually seems downright ''[[DidWeJustHaveTeaWithCthulhu friendly]]''.
** [[SuperpoweredEvilSide Nightmares]] tend to have traits of this, but the "Super Nightmares" (who have managed to mutate somehow) fit it to a T. Nightmare [[spoiler:Whisper is a gigantic, vaguely dragon-like monstrosity with a burned and blackened hole in her chest and exposed with an undead foal inside]] due to [[spoiler:sucking all of Equestria's sins and evil into herself (trapping all those effected in a LotusEaterMachine or reducing them to a foal) and obtaining the Elder Horn.]] Nightmare Mirror is an equally huge MultiversalConqueror with wings covered in ''eyes'' who can [[spoiler:force the victim to witness the harshest truths about themselves]] if they look in them and is described as having a [[YouCannotGraspTheTrueForm constantly shapeshifting form.]] While [[spoiler:Nightmare Eclipse/Paradox]] has a lot of traits of one, she leans more towards being a [[HumanoidAbomination Equineoid Abomination]], though [[spoiler:one of her PsychoRangers, Nightmare Banneret (Spike's Nightmare) resembles one.]]
** [[spoiler: By the time of the FinalBattle between Shining Armor and Makarov, the latter has mutated from a mere [[HumanoidAbomination Equineoid Abomination]] into one of these; merely ''glimpsing'' its true form nearly causes Shining's mind to ''shut down''.]]
** And then there's the Shadows Who Make, Watch, and Rule, beings beyond even the Elders, who Celestia refuses to describe to anyone in-universe, since she knows it would cause them to GoMadFromTheRevelation. [[spoiler: They turn out to be [[HumansAreCthulhu the writers, readers, and Hasbro]], respectfully.]]
** King Sombra is presented as one in the brief OriginsEpisode Alex Warlorn gave him after finally watching Season 3 -- he's the embodiment of the crystal ponies' collective fears, which they were tricked into purging from their hearts by one of Discord's cousins (who themselves count) in the belief that this would grant them further protection from Discord. Instead they got a monster whose every act was literally everything they ever feared would happen to them. [[FromBadToWorse And then]], [[ItCanThink he developed full sentience]]...
* In ''FanFic/UnderTheNorthernLights'', Luna's and Celestia's greatuncles and greataunts are described in a vision as "lights... sounds... patterns of magic in a black sphere that itched the brain and made the soul cry". They decided the laws of nature, seemingly on a whim. The only hostile one seems to be Discord, though, and his reality warping powers are presumably because he never agreed to what his siblings decided. The generation of their parents has some traits of eldritch abominations but are more like OurTitansAreDifferent, having motivations similar to mortal ungulates despite their ancient age, huge size, and inequine shape.
* ''FanFic/TheStarsWillAidTheirEscape'' just cuts to the chase and outright crosses over with the Franchise/CthulhuMythos. Therefore, the BigBad is a stallion avatar of Nyarlathotep who hides his face behind a mask, as seeing it causes the viewer to go insane [[spoiler:which is what happens to Twilight]]; his {{Mooks}} are the Dark Young of Shub-Niggurath; and in true Mythos fashion, Trixie goes crazy after using the ''[[TomeOfEldritchLore Neighcronomicon]]'' and seeing the Young for the first time.
* [[spoiler:Nightmare Phobia]], the BigBad of the [[Fanfic/PonyPOVSeriesChaosVerse Chaos Verse]] (an official spinoff of the ''POV Series''), is made from [[spoiler:the remains of Nightmare Moon's essence]], and exists primarily in the collective subconscious of ponykind. And that's ''before'' she goes OneWingedAngel, at which point she [[spoiler:becomes a sentient void, which consumes Discord's pocket dimension and nearly emerges into the real world, which causes ''every living thing'' extreme pain]].
* [[VileVillainSaccharineShow Of all things]], even ''Blog/{{Moonstuck}}'' gets in on the act with [[spoiler:Discord]]. He uses an EnemyWithout and a personification of depression as his puppets, drastically distorts and at one point ''shatters'' the fourth wall and the ''narration'', and whose speech and appearance are very similar to [[Anime/TengenToppaGurrenLagann the Anti-Spirals]] (probably deliberately, as the author is a fan).
* ''[[Fanfic/AFutureOfFriendshipAHistoryOfHate A Future of Friendship, A History of Hate]]'': The [[BenevolentPrecursors Sentiox]] came into being [[TimeAbyss billions of years ago]] (and have since moved on to another plane of existence), came in a vast variety of forms (some rather normal-looking, some... not), and were powerful enough to create worlds... or in the case of [[BigBad Ruinate]], easily [[OmnicidalManiac destroy them]]. And speaking of Ruinate, he's one of the more otherworldly-looking Sentiox, being a large, vaguely frog-like creature, with three red eyes with cat-like slits, surrounded by (and possibly made of) a miasma of dark energy.
* Parodied by the Blog/ReadingRainbowverse version of the Shadowbolts. They're definitely eldritch, and they can only be seen by Lightning Dust... but they only irritate her instead of driving her mad and the worse thing they've done is draw a penis on her forehead.
* ''FanFic/NightmaresAreTragic'': This is true not only of the villainous and extradimensional Night Shadows, but also of ''all'' Cosmic beings in our own Universe, including not only the Draconequii but even the Alicorns. The Alicorn Avatars in which Celestia and Luna incarnate are AFormYouAreComfortableWith.
* ''FanFic/TheTearsOfGaia'' has [[BiggerBad The Blight]], a sentient [[TheCorruption corruption]] in the form of a black cloud that turns anything exposed to it into twisted, monstrous versions of themselves, driven by a desire to corrupt or kill others. And as shown in the opening CreationMyth, it was even capable of corrupting ''gods'', as it turned Discord and the other Draconequii from benevolent caretakers of the world into monsters out to destroy it.
** For that matter, the Draconequii and Alicorns themselves probably count, being nearly as old as the universe, with their physical forms being AFormYouAreComfortableWith designed to let them walk among their creations. Celestia and Luna are actually ''weak'' compared to their siblings, having given up their divinity to live directly with their subjects.
** There's also the... ''thing'' in the dimensional rift where the Tears of Gaia were stored. We don't get a good look at it, but it's large enough that Twilight and her friends [[ThatsNoMoon mistake one of its eyes for a]] ''[[ThatsNoMoon moon]]'' initially, and the sound of its voice nearly deafens them.
* ''[[FanFic/BlackQueenRedKing Black Queen, Red King]]'' has at least three: [[spoiler: Rex, Queen Chrysalis,]][[note]]Though it's only their souls that qualify. [[spoiler: Rex's]] soul has been described as ''"[his soul] glowed with a blindingly bright darkness."''[[/note]] and Death/Chaos[[note]] Not the same as Discord[[/note]].

[[/folder]]

[[folder: ''Anime/Neon Genesis Evangelion'' ]]

* Ayanami Rei's ''FanFic/NobodyDies'' incarnation is this. And then there's Go-kun's left arm, which he brought back from the ''FanFic/AeonNatumEngel'' verse. The Angels, bizarrely enough, are a bit less Eldritch than they were in the series, due to actually having characters, motivations, and bothering to communicate with the heroes. Even then, constructs like [[spoiler:whatever the hell 02-Ef A9 becomes]] still count.

[[/folder]]

[[folder: ''Video Game/Persona4'' ]]

* [[http://www.fanfiction.net/s/4798922/1/ ''Persona 4: Five Years Later'']] has [[spoiler: Amatsu Mikaboshi, a sentient void without a self-identity, instead referring to himself as "the entity", a barely-sentient but very intelligent incarnation of the Void that existed before time, utterly devoid of human influence. Souji can only classify the Amatsu as pure nothingness, and Igor describes it as similar to Nyx]].

[[/folder]]

[[folder: ''Franchise/Pokemon'' ]]

* ''Fanfic/LatiasJourney'' is chock full of Abominations all led and mostly created by the BigBad Deoxys (who is one himself), being the embodiment of [[ChaoticEvil evil and chaos]]. Others include:
** Dark Latios, the evil undead brother of the main protagonist who ends up [[MindRape mind raping]] her until she transforms into an EldritchAbomination herself.
** Mewgle, a ShoutOut to the Moogles from ''FinalFantasy''. Starting off as the innocent dungeon master of Team Rocket's virtual reality software, Mewgle is recruited by Deoxys and turns into a sadistic KillerGameMaster with JokerImmunity.
** Leviathan, an enormous red serpent who devours all the Ghost Pokemon in the world and is made out of thousands of corpses. Oh, and [[spoiler: she is Latias' mutated mother.]]
** The sequel, ''Fanfic/BraveNewWorld'', has abominations like [[{{Orochi}} Yamatorochi]] and Jovi after Tarantulas's experiments. [[GodOfEvil Giratina]] is still an Eldritch, and other beasties like the [[PlanetEater Gaiavore]] are sure to show up later.
*** Leviathan also returns as a creation of the Ruler of Evil used during the Crisis Wars.
*** Arackaiser [[spoiler: merges the [[FaceHeelTurn legendary birds]] into Maelstrom during the Battle of Shimmer Desert. He does the same thing to the [[BrainwashedAndCrazy legendary beasts]], merging them into Cerberus, who is [[AnticlimaxBoss easily separated]] by Leo]].
* PokemonMysteryDungeonJournal has [[spoiler: Heath, the main character, being revealed as one of these midway through the story. It's a shock even to him.]]
* TheSunSoul has its depiction of Zapdos, who is somewhere between this and OlympusMons.
-->'''Sabrina''': ...a nameless thing [[TimeAbyss predating humanity by countless centuries]]. Team Rocket called it Zapdos, but when I bent all of my power to putting it to sleep and my mind touched its surface thoughts, I immediately knew that [[YouCannotGraspTheTrueForm no name anyone could give that thing could properly describe its... essence]]. Simply forcing Zapdos into a sleep deep enough to allow for safely moving it claimed the lives of two of my psychics. Their minds [[GoMadFromTheRevelation couldn't handle the contact and burned out]], but thanks to them, we safely moved Zapdos to the old power plant and began siphoning off its energy.

[[/folder]]

[[folder: ''Western Animation/The Simpsons'' ]]

* One will be the villain in the upcoming Nathanoraptor fic ''FanFic/TheRedChurch''.

[[/folder]]

[[folder: ''The Slender Man Mythos'' ]]

* * [[TheSlenderManMythos In the Slender Man fic]] ''Fanfic/ByTheFiresLight'', the Slender Man is implied to hail from TheDarkTimes and ends up bringing a bunch of [[EldritchAbomination his pals]] to reclaim the Earth at the end of the story.

[[/folder]]

[[folder: ''Franchise/Sonic The Hedgehog'' ]]

* Dark Tails, the BigBad of ''Fanfic/SonicXDarkChaos''. Born from the dying screams of the Seedrian race, this alien creature initially takes the form of a dark-blue version of Tails with no pupils. He begins to spread [[TheCorruption Dark Chaos Energy]] across the galaxy for his own ends and is literally MadeOfEvil. He brainwashes several of the heroes such as [[spoiler: Venus the Seedrian]] and ''obliterates an entire Angel battlefleet'' by merely speaking to them. During the final battle, he transforms from a gigantic multi-headed space dragon to an [[GeniusLoci entire sentient planet]]. And then he mutates into a [[YouCannotGraspTheTrueForm a literally incomprehensible mass]] of tentacles, eyes, mouths, and [[AndIMustScream voices crying in eternal agony]].
** When Maledict reads a garbled passage from the [[TomeOfEldritchLore Legend of Disaster]], he's struck with a vision of Dark Tails' true form. It's described with such [[PurpleProse flowery]] and [[NightmareFuel disturbing]] images as a staircase descending a nude woman, a [[SurrealHorror moon made of aborted fetuses]], a black lamb with a thousand eyes, a [[AlienGeometries withering plant existing in ten-dimensional space]], and a fox-centipede hybrid with a trillion legs. [[MindScrew Simultaneously]]. And he's ''stunned with horror'' by it. Yes, the true form of Dark Tails is so mind-blasting that it ''terrified Satan himself''.


[[/folder]]

[[folder: ''Franchise/Star Wars'' ]]

* The Forceless Collective in the ''[[FanFic/StarWarsParanormalitiesTrilogy Star Wars: Paranormalities Trilogy]]'' is an entire faction of these from another galaxy. Not only would Force-sensitives sense something off the light-dark spectrum of the Force from these things, but they are disconnected from the universe by being a dead spot in TheForce and are implied not to be natural forms of life. Their primary symbiotic form, the [[BlobMonster Black Matter]], is not unlike Mnggal-Mnggal in the [[{{EldritchAbomination/Literature}} Literature section]]. Unlike Mnggal-Mnggal however, the victims it possesses are still alive and conscious and can live for as long as several thousand years. If the host gets along with the symbiote, everything goes fine for the host, [[AndIMustScream but if not, they lose control of their bodies while they still have access to their senses.]] (and Forceless are usually pretty ruthless). The creatures they possess also get [[BodyHorror mutated]] in the process of symbiosis, and some of them, particularly some of the [[SealedEvilInACan Archfiends]], qualify as abominations themselves.

[[/folder]]

[[folder: ''Video Game/Super Mario Bros'' ]]

* As revealed in Movie 1 of ''FanFic/ClashOfTheElements'', [[spoiler: Pandora, the dragon trapped within Subspace, is one of these, and it is said that it has the capacity to be able to drag an entire world into Subspace if it were to ever fully emerge from a Subspace Orb. It is also stated to have a rather netherworldly glow around it...]]

[[/folder]]

[[folder: ''Video Game/Team Fortress2'' ]]

* In the ''VideoGame/TeamFortress2'' fandom, use of VideoGame/GarrysMod had created multiple popular freaks. The most popular and well-defined are dubbed (in no particular order) Painis Cupcake, Snyphurr, Dic Soupcan, the Odd Scout, and Vagineer. Painis Cupcake twists his body in ways that will instantly kill or disable a normal individual, and is a morbid cannibal who seldom says anything except "I am Painis Cupcake! I will eat you!". Snyphurr is a giant torso with a concealed, bloody head; he turns people into stone. Dic Soupcan floats, mumbles irritatingly, and has multiple Gran-Mal seizures and will regurgitate explosives if agitated. The Odd Scout is distorted past even [[Franchise/TheSlenderManMythos Slender Man]] proportions, converts other Scouts into its own distorted likeness, and can make YourHeadAsplode through eye contact. The Vagineer is the original, and probably the worst, speaking only [[BlackSpeech backwards]] and with powers ranging from using body parts of others to repair itself to corrupting others by its mere presence.

[[/folder]]

[[folder: ''Video Game/Touhou'' ]]

* ''FanFic/ImperfectMetamorphosis'' has the delightful being known as [[spoiler:the Shadow Youkai]]. WalkingWasteland personified, a single touch can result in death, even the most powerful denizens of Gensoukyou are not completely immune from its corruptive power, in addition to its formidable combat abilities. Near-impossible to kill, its vanquishers could only [[SealedEvilInACan seal it]] in a weakened from and strip it of its memories, but that didn't last long. And now, obtaining [[spoiler:the resistance of [[BlobMonster Rin Satsuki]] and the immortality of the Hourai Elixir]], even the combined forces of Gensoukyou may not be enough to stop it in time.
** [[spoiler:The Shadow Youkai]] is a FallenAngel, fine. [[spoiler:Yuuka]], however, is an actual [[spoiler:Outer God]]. As in, the Lovecraftian god-things.
* Yukari Yakumo is depicted as an Abomination so frequently in fanfiction most fans assume its canon, based on her ''extreme'' BlueAndOrangeMorality and [[RealityWarper phenomenal power]] even by Gensoukyou standards. In these depictions the blond woman in a fancy dress is nothing more than [[AFormYouAreComfortableWith a projection for the convenience of others]], and her true form has something to do with her gaps. (Literal tears in reality that contain unending darkness, [[EyesDoNotBelongThere enormous, unblinking eyes]], and disembodied hands attempting to claw their way out.)

[[/folder]]

[[folder: ''Tabletop Game/Warhammer 40000'' ]]

* The Plot Hole from ''Fanfic/{{PRIMARCHS}}''. A living gestalt of all the plot holes accumulated in fiction that wants to eat the universe until only it remains.
* ''TabletopGame/{{Warhammer 40000}}'' has no shortage of this trope, but ''FanFic/TheShapeOfTheNightmareToCome'' adds even more. The New Devourer is an unstoppable tide of death and hunger that eats ''a third of all life in the galaxy'' before inexplicably leaving, with hints that it ate ''everything'' in another galaxy. The Star Father is the GodEmperor made manifest in the Warp, the [[LawfulEvil Chaos God of Order]] that removes all thought and emotion in its subjects, and is so powerful that it took '''all four''' of the other Chaos Gods attacking it at once to prevent it from crushing them. Almost nothing is known of the Ophilim Kiasoz except that it causes entire star systems to ''cease to exist'' simply by being near them. And then there's the Nex, an UltimateEvil at the (maybe) heart of the Warp. To GoMadFromTheRevelation is the ''least'' terrible thing that can happen to you if you learn '''anything''' about it beyond its name.
** The sequel, ''TheAgeOfDusk'', adds Draziin-maton, apparently Pre-Fall Eldar constructs possessed by... something, from layers of Warp so deep that their presence alone turns ''Daemons'' into unfanthomable, mindless chaos.

[[/folder]]

[[folder: ''Literature/Worm'' ]]

* In ''[[Fanfic/{{Propagation}} Propagation]]'' a gigantic, glowing, semi-transparent blue mass of tendrils, hands, and faces manifests at Winslow High due to Eden's core being part of Taylor's Trigger. [[spoiler: It is Taylor's true form.]]
