Animalistic Abomination



A sub-type of Eldritch Abomination, the Animalistic Abomination is a monstrosity that resembles one animal - or often multiple - in a manner that varies from "just significant enough to recognize" to "disturbingly accurate", while still remaining definitely "alien" on the Sliding Scale of Anthropomorphism. However, just because an abomination has an animal's guise doesn't remotely restrict it to an animal's intelligence.

This type can be even more nightmarish than your average horror, due to the contrast of something so thoroughly and decidedly unnatural appearing in a form "borne" of nature. Somewhat less commonly, Animalistic Abominations may actually be a direct product of their environment, which can sometimes suggest that nature itself is harboring a severe animosity towards locals... assuming you're still currently on Earth, anyway.

It is somewhat easy to confuse this trope with Starfish Aliens: these are life-forms most simply adapted to a different environment from humanity and might even take on more familiar forms for our benefit, whereas Animalistic Abominations (like any kind of Eldritch Abomination) will feel wrong and actively tamper with comprehension of it no matter how much they "should" be at home - if it's aware of humanity as a distinct group, then their form being familiar is anything but a good sign for us. Good candidates for such monstrous beings include various reptiles, large insects (and/or arachnids), or cephalopods if you want a nice Cthulhu-esque touch; your abomination may also be based on at least one sufficiently-weird Seldom-Seen Species, or else a combination of various animal species. Heck, you can even make them like actual starfish if you want!

The Worm That Walks may overlap with this, since an eldritch being may use a mass of smalls animals (or animal-like creatures) such as insects to take on a humanoid form. Some variants of this may also overlap with The Mindless Almighty, who tend to possess "animal-like" intelligence at most. Contrast the Tortured Abomination, which has a feral mentality rather than appearance.

Anime and Manga

 * Berserk has the Beast of Darkness, a monstrous wolf that is Guts's bloodlust and hatred of Griffith given form. It's one of the swordsman's greatest enemies, and wants nothing more than to make him submit to his darkest desires so it can permanently steal control of his body and freely indulge in its psychopathic bloodlust.
 * The Tailed Beasts of Naruto fame are dangerous monsters made of primal Chakra, and look like massive and unholy versions of otherwise ordinary animals: the Eight-Tails resembles a skinless ox with octopus tentacles; the Yonbi, or Four-Tails, looks like a monkey; and the Nine-Tails is naturally a demonic-looking fox. Most have been sealed inside of human hosts in hopes of keeping the unruly beasts under control, but this often results in the hosts going insane, or else having control of their bodies ripped away by the beasts possessing them - that is, if they're not warped beyond recognition either way. All Tailed Beasts have names given to them by the Rikudo Sennin himself: Shukaku, Son Goku, and Kurama (the Kyubi) are the only ones known. And according to the Hachibi,.
 * Puella Magi Madoka Magica has a heavy spoiler example in.
 * The reason for doing all this to begin with is that.
 * The side-story manga Puella Magi Kazumi Magica also has similarly-spoilery examples:
 * In The Rebellion Story, set after the series,
 * In Pokémon: Jirachi—Wish Maker, the villain Butler attempts to resurrect a Groudon from a fossilized remnant of it using Jirachi's wish-granting powers. When he finally succeeds, the result is a bizarre manifestation of pure evil looks like Groudon, but pretty clearly isn't - this Groudon-shaped monster (known as Meta Groudon in Japan) immediately begins absorbing energy from plant life, humans and Pokémon alike using the gelatinous tentacles expelled from its spikes. It takes Butler seeing the error of his ways and collaborating with Jirachi as well as Ash and his friends in order to finally destroy the monstrosity.
 * In the Witch Hat Atelier manga, the Brimmed Caps possess Black Magic transformation spells which can turn them into scalewolf-like abominations against their will - while they share the canine appearance and scaly back of actual scalewolves, these monsters are black-colored beasts with pupil-less eyes.

Comic Books

 * In Bone, the Big Bad of the entire story is revealed to be . Its Dragon is The Hooded One - . According to the prequel comic Rose,.
 * One Donald Duck issue reveals that a giant octopus called Ar-Finn sleeps beneath the depths in a sunken city - Cthulhu and R'lyeh, anyone? Donald's reality exists only because Ar-Finn dreams about it: If he wakes up, the world will start to adapt to his image, with the architecture becoming more and more alien and the people more octopoid in appearance. The story ends with Donald horrified to find out that our whole existence is just a dream.
 * Lord Odacon of 2000 AD comic Slaine leads an entire species of these. They are cousins of the Humanoid Abomination Fomorians, and are Puppeteer Parasites that look equal parts deep-sea monstrosities and aborted hell-larvae.
 * In DC Comics:
 * The Green Lantern comics have revealed the existence of alien entities that are incarnations of the various emotional forces that power each society of Lanterns. Examples of this trope among them include the bull-like red Butcher of Rage; the insectoid yellow Parallax of Fear; the three-faced, eagle-like blue Avara of Hope; and the massive, octopus-like indigo Proselyte of Compassion.
 * The Red is an an elemental force that connects all forms of land-dwelling animal life on Earth, and is governed by a group of entities known as the Parliament of Limbs. As a close ally of the plant-centric Green, the Red is far from malevolent and is connected to well known superheroes such as Beast Boy (formerly Changeling), Vixen and Animal Man, but it's... not exactly pleasant to look at.

Fan Works

 * The fanon of My Little Pony: Friendship Is Magic likes to do this with many of its pony characters, as well as the Big Bads.
 * The original Garry's Mod Applejack model was so freaky that it was reinvented as Eppaljeck, in the style of other GMod abominations.
 * Popular fanon is that Celestia and Luna, rather than being Physical Godesses, are benevolent versions of this trope, considering their incredible age, almost unmatched power, Non-Standard Character Design, and being worshiped as deities by their subjects with a combination of unquestioning obedience and paralyzing fear. Luna is more frustrated that being imprisoned in the moon for a thousand years means she's a Fish Out of Temporal Water, rather than from being imprisoned for a thousand years. One fanfiction even 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 other ponies are continually reminded that the two are very much Other.
 * Cloudcuckoolander and Genki Pony Pinkie Pie is also sometimes speculated to be an Equestrian Abomination, and there is a disturbingly high amount of supporting evidence, what with her tendency to casually break even the magical rules of Equestria: this especially includes appearing 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. And it's especially notable that when Discord first appeared, everypony else (including Celestia) was fearful while Pinkie was ecstatic.
 * The Pony POV Series has several - the most obvious are
 * In Under The Northern Lights, Luna's and Celestia's great-uncles and great-aunts 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 abominations but are closer to titans, having motivations similar to mortal ungulates despite their ancient age, huge size, and in-equine shape.
 * The Pokémon fanfic Latias' Journey is chock full of these, all led and mostly created by the Big Bad Deoxys, who is the embodiment of evil and chaos. Others include:
 * Dark Latios, the evil undead brother of the main protagonist who ends up mind raping her until she transforms into an Eldritch Abomination herself.
 * Mewgle, a Shout-Out to the Moogles from Final Fantasy. Starting off as the innocent dungeon master of Team Rocket's virtual reality software, Mewgle is recruited by Deoxys and turns into a sadistic Killer Game Master with Joker Immunity.
 * Leviathan, an enormous red serpent who devours all the Ghost Pokemon in the world and is made out of thousands of corpses. Oh, and.

Film

 * The titular monster of John Carpenter's The Thing is first shown in the very convincing guise of a sled dog, running towards an American research station in Antarctica. When it's placed in a kennel with other dogs on-site, they immediately realize it's nothing like them and act hostile towards it, just before it transforms to attack the other dogs and absorb most of them.
 * In Annihilation, animals exposed to the Shimmer are mutated into a form that, while recognizable, are far more alien and freaky than anything found on Earth. On the more mundane side of things is an alligator with a mouth full of shark teeth, while far more extreme is a bear with its skull exposed that can mimic the dying screams of a human it killed, and has one of her eyes and quite possibly her entire skull assimilated into its being.
 * Pirates of the Caribbean has Calypso, the goddess of the sea whose favored form seems to be a vast swarm of crabs. The Kraken would also count, from the way Gibbs describes it.

Literature

 * The works of J. R. R. Tolkien, such as the The Lord of the Rings, have quite a few examples:
 * Shelob is a terrifying giant spider who happens to be the daughter of Ungoliant, a monstrous Eldritch Abomination that terrorized Middle Earth before Sauron rose to power. While she doesn't possess her mother's apocalyptic appetite and godlike strength, she's still one of few beings that the One Ring has no power over, and is framed by the narration as being less an animal and more a demon masquerading as one.
 * The cephalopod-like Watcher at the gates of Moria may be one of those things that managed to crawl its way up to the surface, or it may be one of Morgoth's creations, but either way it is a borderline abomination.
 * Nodens, Lord of the Abyss, is an Elder God that appears in the Cthulhu Mythos, and is one of the few Elder Gods created (though not referred to as such) by Lovecraft himself. An enemy of Nyarlathotep, Nodens generally appeared in a humanoid form, which may either be his true form or one he took in order to not drive mortals insane.
 * Stephen King works feature a veritable assortment of creepy-ass creatures.
 * At one point in IT, the eponymous monster is perceived as a Giant Spider by the protagonists, because this was the closest analogue that their rational minds could find for Its appearance. Before that, it appeared as . The true identity of IT is.
 * The Dark Tower: Mordred Deschain is a half-demon who normally appears human, but when threatened he becomes a spider-like monster.
 * In Pet Sematary, anything buried in a particular cemetery will be resurrected as a Monster From Beyond the Veil - and many children had their dead pets buried there.
 * The Ancient Enemy from Dean Koontz's Phantoms is a massive, lake-sized mass of black sludge older than the dinosaurs that consumes other life forms as sustenance, and is able to perfectly mimic any creature it consumes. It can also create examples of these in small "probes" or "phantoms" that imitate the life forms it's consumed, including animals, to go forth and hunt more prey.
 * In The Power of Five, the main antagonists are examples of this.
 * Perdido Street Station by China Mieville:
 * The slake-moths - monstrous, insectoid creatures that feed on the very sentience of their prey, leaving their victims utterly mindless shells. How terrible are these abominations? At one point, the government of New Crobuzon attempts to strike a deal with Hell to get them to intervene and stop the threat, and the demons are too frightened to get involved.
 * And then you have the Weaver, who the New Crobuzon government turns to when the demons turn them down. It's a gigantic spider that exists between dimensions and is capable of traversing them as easily as we would walk down the street. It is also batshit crazy, speaking in the "flight of ideas" style most often seen in unmedicated schizophrenics and capable of doing anything to anyone, friend or foe, merely because it seems "fitting". During the brief time that the heroes are in its presence, the Weaver cuts off the ears of everyone in the room for reasons known only to itself. It also repaired the ears of some of the people, again for reasons unknown. It also has an obsession with scissors and happily accepts them as gifts, if the term 'happy' can be applied to it; apparently it enjoys collecting things in general, as it is mentioned that before its obsession with scissors, it collected chess sets.
 * The Creepers encountered in the works of Terry Brooks were created by the Shadowen, and are creatures of composite machine, insect, and mammal.
 * While The Bible does not go into detail about the origins of the Serpent in the Garden of Eden, Paradise Lost leaves no question that it is Satan in disguise.
 * The Hound of the Baskervilles has the titular canine, which is implied throughout the novel to be a sort of demonic hound.

New Media

 * The Dogscape, a creation of Something Awful and 4chan's /co/, is a colossal organic mass of dog parts smothering the entire globe, leaving only trees growing puppy fetuses and occasional masses of milk teats as the only sustenance for the few remaining scraps of humanity.
 * Thanks to Tumblr, the My Little Pony: Friendship Is Magic fandom now has Loony Luna.
 * From Something Awful Zoofights, we have Swanmass. It starts out as a bunch of swans with gorilla arms, but after the Zoofights people reanimate it with Black Magic, it gets much, much worse.

Oral Tradition, Folklore, Myths and Legends
"The locusts looked like horses prepared for battle. On their heads they wore something like crowns of gold, and their faces resembled human faces. Their hair was like women’s hair, and their teeth were like lions’ teeth. They had breastplates like breastplates of iron, and the sound of their wings was like the thundering of many horses and chariots rushing into battle. They had tails with stingers, like scorpions, and in their tails they had power to torment people for five months."
 * The Bible:
 * In Chapter 9 of the Book of Revelation, the first eleven verses describe "locusts" that are summoned from the Abyss, and appear as armored horses with human faces, long hair, scorpion tails and leonine teeth. Unlike a typical Plague of Locusts, they were sent to torment and harm "those people who did not have the seal of God on their foreheads" for nearly half a year; they are also led by the angel of the Abyss, known as Abaddon in Hebrew, and Apollyon (or "Destroyer") in Greek. From Revelation 9:7-10:


 * The Black Shuck of English folklore is a canine apparition that is frequently recorded as an omen of death, and other legends of spectral black dogs have been linked to it. The Shuck tends to appear as a shaggy black dog of varying description, with consistent traits including fiery eyes (or sometimes eye, as captured in the page image) and its immense size. In the most notable report, the Shuck was said to have burst through the doors of a church with the sound of a thunderclap, killing two people and causing the church steeple to collapse through the roof, and then leaving scorch marks on the north door as it disappeared - the account's author describes it both as a black dog and "the divel in such a likenesse". Another account recorded in the Peterborough Chronicle suggests that Black Shucks are used as part of a Wild Hunt.
 * Norse Mythology has numerous examples:
 * Fenrir, or Fenrisúlfr - the Big Badass Wolf among Big Badass Wolves and one of Loki's three monstrous children by a female jötunn (often translated as "giant", despite not every jötunn being especially large). The Æsir raised Fenrir among them while devising a plan to try and permanently bind the ever-growing canine - they coaxed Fenrir into testing fetters through promises of fame for his strength, and when placing the dwarven-made Gleipnir Fenrir suspected there was trickery afoot, but allowed them to test it on the condition that Týr place his hand in Fenrir's mouth as a pledge of good faith. As the only one who had been courageous enough to approach and feed the wolf, Týr obliged - when it turned out that Gleipnir would hold, so did Fenrir, and off came the hand. The gods then thrust a sword into his mouth when he tried to bite them, holding it opening and gagging him; this caused him to produce horrible howls as saliva ran from his mouth, which formed the river Ván (Old Norse "hope"), and so he would remain bound until Ragnarök comes.
 * And when Ragnarök comes, Fenrir is prophesized to break his binds and "go forth with his mouth opened wide, his upper jaw touching the sky and his lower jaw the earth, and flames will burn from his eyes and nostrils" - he will aid the forces of Surtr alongside his sibling, the World Serpent (who is another example discussed below), and consume the King of the Æsir, Odin.
 * Fenrir's sons, Sköll and Hati Hróðvitnisson, are each a Big Badass Wolf in their own right, and eternally chase the sun and moon respectively across the sky; one of the signs heralding Ragnarök is Sköll eating the sun and Hati swallowing the moon. Then, the stars will then disappear from the sky, the earth will shake violently, trees will be uprooted, mountains will fall, and all binds will snap – and then their father will break free.
 * Jörmungandr the Midgard Serpent, one of the monstrous offspring of Loki and a giantess. Starting out big, he grew so large that he can encircle the world, and sleeps at the bottom of the ocean depths while keeping his tail in his mouth - one of the signs of Ragnarök is finally releasing his tail, then causing to seas to flood as he thrashes onto the land and fills the water and air with his poison. Joining Loki and his other children in confronting the gods, Jörmungandr's role in the conflict is a battle with his Arch Enemy Thor that ends in a Mutual Kill - the hammer-wielder successfully slays the Serpent, but is felled by his poison after walking nine steps.
 * Garmr, another monstrous wolf guarding Nifhelm.
 * Norse folklore originated the Kraken of the Kraken and Leviathan trope.
 * Egyptian Mythology:
 * Apep (Greek "Apophis") is an example that makes the trope Older Than Dirt: he is a titanic snake (or sometimes a crocodile) that represented the primal chaos of darkness, and is thought to dwell in the underworld. Apep would regularly attack Ra as his solar barge made its daily sojourn through the 12 Hours of Night, and was sometimes thought of as an Eater of Souls. Apep is notably the closest thing in the folklore to a captial-D Devil-figure - the Egyptians often buried their dead with spells that could destroy Apep, and any "worship" that related to Apep was with the aim of repelling or purging his influence, such as the annual rite called the "Banishing of Chaos" where he was burnt in effigy. Egyptian priests even had a detailed guide dedicated specifically to fighting Apep, referred to as "The Books of Overthrowing Apep" (or "The Book of Apophis" in Greek). Even Set - a remarkably vicious and evil deity in his own right, to the point of constant and sometimes literal Demonization - was said to protect Ra against Apep's onslaught during his journeys.
 * Ammit is a demon who devoured the souls of evildoers in the Hall of Judgment, and was a giant combination of a crocodile, hippopotamus, and lion - three animals that Egyptians (rightfully) feared the most.

Tabletop Games

 * Dungeons & Dragons:
 * One of the various backstories of Asmodeus, the Lord of Nessus and King of Hell, is that he is actually one of these. What others see when dealing with him is actually an advanced illusion - Asmodeus' real body is that of a titanic, miles-long serpentine creature who is some sort of primordial entity that predated the Gods, and is still injured from the Gods throwing him into an abyss so hard, it created the Nine Hells.
 * Possibly the Froghemoth, which is a frog the size of an elephant, standing upright, with three eyes, and four tentacles in place of arms. While this is indeed weird, the "abomination" part is a theory put forth by Baron Lum the Mad, who claimed to have encountered strange, cylindrical chambers of metal buried in the ground from which froghemoths emerged (of course, there is a reason Lum was called "the Mad"). Also, in Forgotten Realms, there is a legend stating that the primordial god Ubtao created froghemoths, first doing so by transforming a toad who dared to insult him; also, Kubazan, one of the Nine Trickster Gods of Chult, tooks the form of a Froghemoth. This suggests these monsters are at least originally divine creations. Whatever the case, it is clear they are "not of this world".

Video Games

 * Undertale has one of these in.
 * Bloodborne has many, but the Cleric Beast and Vicar Amelia are among the most iconic examples. They look like massive bipedal wolves with reindeer antlers that have been starved to death, and their screams sound truly hellish. Both seem to be some form of Wendigo, with the latter introducing herself by erupting forth from the body of a seemingly normal priestess.
 * Barbas from The Elder Scrolls is a benevolent and adorable example, being a talking Big Friendly Dog with a Brooklyn accent and the best bud of Daedric Prince Clavicus Vile... as well as an aspect and the conscience of the Prince himself that tries to protect anyone unfortunate enough to bargain with him. Furthermore, The Elder Scrolls: Redguard shows that he doesn't strictly stick to the form of a dog, and can be seen randomly changing forms before resetting back to his dog form. Clavicus will even comment on it, saying that he likes being a dog on sunny days, as well as many other things.
 * Since the Heartless from Kingdom Hearts are an entire race of Eldritch Abominations, the ones with more animalistic forms fit this trope, such as the Powerwilds, Bouncywilds and Pot Spiders. But even among them, there are a few that stand out:
 * Skoll, a massive wolf Heartless named after the giant sun-chasing wolf from Norse Mythology. It fights by summoning packs of ghostly wolf minions, firing off powerful ice attacks, and trying to crush Sora and friends underneath a mass of darkness big enough to fill up the sky. But what makes it really special is the fact that it's the Heartless of Prince Hans himself, who's been completely corrupted by the darkness in his heart.
 * Scar similarly becomes consumed by hatred and rage - but unlike Hans, his inner darkness is so powerful that he manages to hold onto his original form after becoming a Heartless... a feat only shared by Ansem, Seeker of Darkness..
 * The Halloween Hack has the Desire Dog that appears in - it appears as a Zombie Dog in the overworld, but in-battle the front half of its body consists of gooey tentacle-like pseudopods that it frequently uses to attack. Upon defeat, it collapses into an array of wriggling tentacles.
 * Final Fantasy:
 * Final Fantasy VIII: During the third stage of the Final Boss, Ultimecia the Sorceress (a Sorceress effectively being an enhanced human) junctions herself unto the Guardian Force Griever, resulting in a hybrid felinid form with Ultimecia's torso and arms on its chest, and deformed limbs and wings resembling Ultimecia's.
 * Sin of Final Fantasy X manifests as a giant whale-like monster the size of an entire city, and emerges from the depths of the ocean to completely annihilate all settlements larger than small villages at random intervals. It leaves swarms of smaller monsters in its path and everyone who survives coming into contact with its toxins (fortunately) suffers from massive memory loss. It can also apparently wipe out entire armies by causing distortions of space.
 * Deadly Premonition has one where you'd least expect it, personally confirmed by the creator:.
 * In Monster Hunter, Elder Dragons as a whole are essentially this by the standards of the local fauna. They're incredibly powerful monsters that don't fit into the tree of life like every other monster classification, and often have their powers manifest in ways that can't be explained away by an elemental sac or any biological function. Many are either worshiped and revered as gods, or else feared as demons, and their presence drives away other monsters through an environmental anomaly.
 * The Elder Dragon Yama Tsukami is weird even by this standard - it looks nothing like a traditional dragon and more like a gigantic floating octopus covered in moss and earth, possessing a mouth full of disturbingly human teeth. It isn't aggressive or malicious, but it can destroy entire ecosystems by devouring everything it flies over, including entire lakes and forests.
 * Fatalis and its relatives are easily some of the most eldritch and unholy monsters in the series, which is no small feat. Armor and weapons made from their body parts are said to plague those who wield them with horrifying nightmares, dark voices in their heads, and animalistic bloodlust; the Fatalis sword in Pokke village is constantly regenerating scales as well... These weapons and armor tend to driver their users insane if they don't die under mysterious circumstances - they can also possess their wielders, and possibly turn them into another Fatalis entirely. Between this and, this implies that it's impossible to truly kill a Fatalis since they'll always find some way to resurrect. Their powers are also anomalous even by the standards of other Elder Dragons: Crimson Fatalis can send meteors crashing down to Earth, while the White Fatalis is introduced triggering a solar eclipse by emerging from a mysterious portal, hinting that it might be extradimensional to some extent. The standard Black Fatalis is comparatively more mundane, but even it famously wiped out an entire civilization overnight.
 * In a series where wielding two different elements can make a monster especially dangerous, Alatreon having power over all of them is downright mind-breaking. While it doesn't go out of its way to cause chaos, its powers are so unstable that it's practically a natural disaster in the form of a dragon. Like with Fatalis, equipment made from its body parts are said to drive the wielder completely insane over time.
 * Dire Miralis, which is treated less like a monster and more like Satan himself, is feared as a harbinger of the apocalypse. A titanic Elder Dragon that looks like a Fatalis carved out of volcanic rock, Dire Miralis's body can naturally generate lava that it fires from its "wings", which are basically an organic gun battery as opposed to any sort of proper animal appendage. It's so powerful and destructive that it can sink entire islands, and even when it isn't being actively malicious it can still boil entire oceans into lifeless wastelands just by stepping into them. Like with Fatalis, it's hinted that killing it doesn't even stop it for good, since its heart beats independently of its body and is rumored to be able to regenerate a completely new Dire Miralis over time.
 * Gore Magala looks like the unholy spawn of Venom, a Xenomorph, and a dragon, and is such a biological anomaly that no one really knows what to classify it as, ultimately settling for a class simply labeled as "???". It's essentially a plague given life, and casually spreads a virus that turns monsters exposed to it into rabid berserkers..
 * Gogmazios is framed as something truly horrible and unknowable, even by the standards of this series' Elder Dragons. It looks like a skeletal dragon submerged in a tar pit, which said tar being passively generated from its body and weaponized in the form of explosive projectiles and super-heated tar lasers. And despite being roughly as big as Godzilla, it's a skillful flier and stealthy to the point that there are no recorded sightings prior to the player's encounter with the beast. Some players believe it to be a heavily mutated relative of the Gore Magala, while others believe it to be the fabled Equal Dragon Weapon from the series' old concept art and background lore. But if there's one thing the fandom can agree on, it's that its weird biology, bizarre powers, and mysterious nature make it feel like an obscene and otherworldly anomaly.
 * The Legend of Zelda franchise has Ganon, who often appears as a large boar-headed demonic being and sometimes even closer to an actual boar (though still monstrous and far from any less abominable).
 * The Legend of Zelda: Twilight Princess has the second stage of the Final Boss:
 * In The Legend of Zelda: Breath of the Wild, during the Final Boss fight.
 * Super Smash Bros.:
 * Ganondorf turns into his demonic boar form as part of his Final Smash from Super Smash Bros. Brawl onward.
 * Super Smash Bros. for Nintendo 3DS / Wii U introduces the Master Core - either a superpowered form of Master Hand, or some sort of abomination that took his guise. It surrounds itself with The "Swarm", a mass of darkness that it can shape into a number of terrifying forms: the ones that qualify for this are the Master Beast, which appears as a scorpion-tailed hound with violent high-speed attacks and bites that can shake the stage, and the Master Shadow if you're using an animal-like fighter such as Donkey Kong.
 * Falzar and Gregar from Mega Man Battle Network 6 overlap with Mechanical Abomination - both are obscenely powerful, animalistic superprograms that are feared as harbingers of the apocalypse, and serve as the game's version mascots. Gregar is a wolf-like amalgamation of Bugfrags not unlike Gospel, and Falzar was meant to be a countermeasure to Gregar that turned violent and unpredictable. When MegaMan.EXE is forced to absorb one, he turns into a feral and uncontrollable Mechanical Abomination due to their raw power, with his appearance altered accordingly.
 * The Pokémon series has an abundance of examples, typically in the form of its Olympus Mons.
 * The super-ancient trio of Pokémon Ruby and Sapphire - Groudon, Kyogre, and Rayquaza - are Weather Control Creatures that lurk in places normally beyond the reaches of man, and the awakening of either the dinosaur-like Groudon or the whale-like Kyogre alone constitutes an apocalyptic event that could devastate the world. The third version, Pokémon Emerald, has both of them awakened, forcing you to find Rayquaza in order to force them back into slumber. All three of them are at least Phsyical Gods with an ability to control the continents, ocean and sky, respectively, and they're all believed to be hundreds of millions of years old. Where Groudon and Kyogre can also induce droughts and flooding, Rayquaza can outright force clear skies with its presence.
 * The fourth generation of Pokémon introduces several examples: the creation trio of Pokémon Diamond and Pearl are Dialga, Palkia and Giratina, draconic Pokémon that embody the concepts of time, space, and anti-matter.
 * Giratina rivals both Dialga and Palkia in power, and dwells in the Distortion World, a dimension where time and space do not work like they should. It can travel to different universes, and warp reality. There's a good reason why people compare it to Yog-Sothoth or even Satan.
 * Arceus - the Alpha Pokémon and "The Original One", it is the creator of the lake guardians and the creation trio, possibly the Sinnoh and Ransei regions, and maybe even the entire Pokémon universe. It is said to have created the universe with "one thousand arms", and can change its type to any of the other 17 through the use of Plates and Z-Crystals. It also lives in a pocket dimension, the Hall of Origin, seemingly located above Dialga and Palkia’s summoning grounds on Spear Pillar, and all music associated with it just sounds... wrong.
 * As shown by an event involving a special distributed Arceus in Pokémon HeartGold and SoulSilver, it can recreate the latter trio of Pokémon, presumably to guard the dimensions when a Trainer has caught one of them... preceded by its battle theme playing over a disorienting and terrifying series of Mind Screw-inducing images.
 * The fact that you can catch such world-changing entities to begin with is worthy of noting - Poké Balls work as power limiters that allow you to control what you catch with them. As pointed out by Ghetsis in Pokémon Black and White: "A Pokémon, even if it's revered as a deity, is still just a Pokémon" - this also factors in the plot of Cyrus, who wants to control Dialga and/or Palkia in Pokemon Diamond/Pearl/Platinum by using the Red Chain rather than any type of Poké Balls.
 * Xerneas and Yveltal of Pokémon X and Y are the incarnations of life and death, respectively, and otherworldly to a T. Xerneas breaks the usual mold of cute, cuddly Fairy-Types and is a divine, imposing stag who can grant eternal life to those it deems worthy. Yveltal, on the other hand, is a ghastly vulture-like Pokémon who can suck the life out of people, Pokemon, and the very Earth itself, rendering its victims statues; when it reaches the end of its lifespan, it steals the life energy of everything around it and then transforms into a cocoon to sleep. Living being drained by Yveltal can only be restored to life by Xerneas.
 * Eldritch as they are, neither Xerneas nor Yveltal hold a candle to the third member of their trio: Zygarde. While Xerneas and Yveltal at least have recognizably animalistic forms, Zygarde is a hive mind collective of tiny cell-like creatures; depending on the amount of Zygarde Cells gathering around a "Core", it can take on the appearance of a hound, a bizarre alien serpent, or a hulking monstrosity that looks like some sort of alien Gundam. No matter the form, it’s a hyper-vigilant protector of nature that will eliminate any and all threats to the ecosystem with extreme prejudice. Thankfully, it's an otherwise benevolent and gentle creature.
 * The Ultra Beasts of Pokémon Sun and Moon are only barely recognizable as Pokémon, and are interdimensional beings whose appearances and powers are unlike those of even the most Eldritch Pokémon. Those the most fit this trope include:
 * Nihilego looks like an oddly humanoid jellyfish, but is inexplicably a Rock/Poison type instead of anything even remotely aquatic. It secretes a venom that turns victims into rabidly insane husks of their former selves, and drives the conflict behind Pokémon Sun and Moon by.
 * Serving as something of an unofficial "leader" of the Ultra Beasts, Guzzlord is a gluttonous Draconic Demon that acts as a living black hole. Its monstrous appetite allows it to devour anything, whether it be people, buildings, or nuclear waste, and convert it all into energy. It never leaves any waste behind, and is hinted to have been created by nuclear disasters that devastated its home dimension.
 * Pokémon Legends: Arceus marks the first non-event appearance of the titular Mythical Pokémon and reveals even more about Arceus and the creation trio.
 * Two of the trio - - each have their own Origin Formes, which partly explains why.
 * And what of the titular Arceus?
 * Several of the Glitch Pokémon that appear as other Pokémon fit this on a conceptual level, including Missingno. - glitch Pokémon on a gameplay level are essentially junk data given form, and as such the game will pull the images and cries of other 'Mons from the index for them. Many of them warp or alter music, graphics and save data, possess bizarre dimensions, and can induce game crashes; some such as 'M and its Yellow counterpart 3TrainerPoké $ can even evolve into actual Pokémon!
 * MissingNo. in particular is known for its ability to duplicate items, mess with save data like the Hall of Fame entries, and scrambling in-sprites when sent out to battle. It has three "special" forms in Pokémon Red and Blue as well as Yellow: two of them resemble the Kabutops and Aerodactyl fossils from the Pewter Museum of Science, due to the game using the index numbers of these images to get their front sprites. In these forms, MissingNo. has no constant base stats, experience types or starting moves, instead copying those of the last Pokémon in the party (minus another special MissingNo.); a "special" MissingNo. sent out by a rival Trainer instead takes on the qualities of the previous Pokémon they sent out.
 * The Elder Scrolls has a lot of eldritch monsters hanging around, and with the vagueness surrounding the franchise's intentionally contradictory lore, it only figures that some of them are animal-like in nature:
 * While they don't look too different in comparison to your stereotypical sauropod-like Western dragons, the dragons of The Elder Scrolls aren't fire-breathing lizards so much as they are Draconic Divinities (or Demons) with a connection to Akatosh himself. They're immortal creatures that can't be permanently killed unless their souls are absorbed, and find mortality to be so alien of a concept that it hurts them if they're forced to comprehend it. They also don't breathe fire, but instead speak it into existence, with the dragon language giving them all sorts of other fantastic powers that include becoming ethereal and greatly weakening anyone they fight.
 * Alduin, one of the most powerful dragons in the series, cranks this up even further. He is either the firstborn son of Akatosh, an aspect of him, or Akatosh himself, and that's ignoring the likely explanation that he's all three at once somehow. His powers go further beyond his weaker brethren, and include being able to raise dragons from the dead as well as . His role is meant to be that of a living apocalypse that plays into the world's cycle of death and renewal, hence his moniker "The World-Eater".
 * Some examples lurk among the horrors infesting Spooky's Jumpscare Mansion:
 * Specimen 8 looks like a humanoid deer wearing a robe, but its "body" is a mass of screaming faces of its past victims tucked under its rib cage. It kills its victims by assimilating them into itself, and every time it attacks you you're assaulted by disturbing imagery in the form of subliminal messages and sudden closeups of its freaky face.
 * Hollow Knight has a spoiler-riffic example:
 * In Might & Magic 9, the Great Honk is implied to be this. The Founder of the Temple of Honk stated that devout believers could achieve spiritual redemption via the Way of the Bread (which stated one should never get agitated and should instead rise up over adversity) which would result in the Great Honk’s blessing causing them to be reincarnated as geese. (The present-day cult is far less benign.)

Visual Novels

 * In the Nasuverse, Tsukihime has Nero Chaos, whose body is composed of hundreds of animals that can detach from him to attack and feed.

Web Comics

 * Apparently, in a Dinosaur Comics Alternate Universe that's the result of For Want of a Nail, gazing upon T-rex and Utahraptor's true colours would cause one to Go Mad From the Revelation.
 * xkcd features Sheeple. Do not wake the Sheeple.

Web Original

 * SCP Foundation:
 * A prime example is SCP-682 ("Hard-to-Kill Reptile"). A reptillian being of indeterminate gender, it's not only extremely intelligent and capable of speech, but also ridiculously adaptive, extremely destructive and tough to bring down - and the Foundation wants it destroyed as soon as possible. It has regeneration abilities that allows it to survive several factors of otherwise-lethal force - extensive testing reveals that anything that even manages to do significant damage only "works" once. What makes it abominable is that, as indicated by its own words, it finds human life "disgusting" and tries its damnedest to kill anyone and everyone it can get within reach of - the SCP thought to be God by the Foundation claims it's "not one of his", and it is such a biological mystery that researchers wonder if it's even "alive" insofar as we understand the concept.
 * ...And as shown by that testing and its character page, the questions don't end there. It's well-established that said testing is extremely unlikely to result in a successful kill - beyond gauging its durability, these tests would ideally reveal more about the creature's properties and origins.
 * It is implied that the Scarlet King might have had some hand in creating SCP-682, giving it divine blood and possibly even making it a sort of Anti-Christ.
 * SCP-5683 is an arachnid-like being that adapts its form to resist anything posing a danger to it. It doesn't seem to be particularly intelligent, but is smarter than it looks and still a capable hunter, especially with its ridiculously adaptive body - it's extremely destructive and tough to bring down, and the Foundation wants it neutralized as soon as possible. It absolutely hates humanity and tries its damnedest to kill anyone and everyone it can get within reach of - does all this sound familiar? One of the staff assigned to it even dealt with SCP-682 previously, and seems quite ambitious about it.
 * SCP-5962 overlaps this with Monster Clown. Biologically, this creature is a cow and was born from one at a Midwest American farm, but it resembles a monstrous version of Ronald McDonald that is 4 meters tall and weighs over 5 tons, and it continually spits out fully-packaged McDonalds products. The owners of the farm sold it to a Chinese McDonalds franchise, where they enjoyed an incredible boost in profits for a while until the Foundation found out about it. They also found out that the food was made from human flesh - all of it. The bacon and fries are human cartilage and ligaments; the chicken nuggets were made from reproductive organs; the bread is made of hair, nails, and skin; and the coffee and ice cream were made from... various human waste products. (Yeah, a lot of folks in-story were grossed out too.) The weird part is, nobody knows where the stuff comes from: SCP-5962 has never been known to attack anyone save one time when it spewed hot coffee on a visiting Burger King manager, possibly the guy who tipped off the Foundation; it seems relatively mindless and never really does anything except produce the food - when analyzed, the food's genetic material matches that of still-living humans, who seem unharmed by this process.
 * SCP-5962 isn’t even the only example of this trope that came from that farm. SCP-4158 is the other; it looks closer to a cow than SCP-5962, but is huge, monstrous, and deformed. Some sort of anomalous birth defect gives it uncontrollable regenerative ability, causing it to grow at an alarming rate, requiring the Foundation to sever its limbs and shear off parts of its muscle on a weekly basis, lest the poor beast’s spine snap under its own weight - fortunately, the same condition makes it oblivious to pain, and it seems docile and harmless. Meat sheared off of SCP-4158 is edible and safe (in fact, its original owner was selling it for such) but few people are willing to eat it if they know where it came from…
 * RWBY: The Grimm are monsters that resemble animals that feast on humans and are attracted to their negative emotions. Their forms consist of black hides with outward skulls and bones throughout their bodies.
 * The Rake is a well-known creepypasta creation that's a freakish hairless dog-man with seemingly similar stalking habits to Slenderman, albeit being more direct with his victims: Where Slendy watches from a distance, the Rake likes to sit on your bed. While you're in it. He's even been integrated into the mythos of Everyman HYBRID.

Western Animation

 * The Talking Cat from the Rick and Morty episode "Claw and Hoarder: Special Ricktim's Morty". This creature seems to be your average Talking Animal at first, but its true form (which the viewers do not see) is so horrific that it actually caused Rick, who has stood up to planet sized Eldritch Abominations and The Devil himself without fear, to panic and nearly commit suicide.
 * My Little Pony: Friendship Is Magic:
 * Discord, the mismatched spirit of chaos and disharmony. Possessing Reality Warper powers so formidable he would be unstoppable if it weren't for the Elements of Harmony (not even Celestia and Luna could defeat him without them), within hours he plunges Equestria into a World Gone Mad and a World of Chaos, seeking nothing more than his own amusement and thoroughly breaking ponies.
 * The Windigos that appear in "Hearth's Warming Eve". Spirit horses that feed on hatred to bring eternal winter, they're even based an awful lot off the version of the Wendigo from the Cthulhu Mythos, who was an Eldritch Abomination as well.
 * Word of Dante has it that Nightmare Moon also shows traces of this, as not all of her is Luna.
 * Used as a Brick Joke in The Owl House. In the first season, Eda tells Luz that giraffes are natives of the Boiling Isles; the "joke" is supposed to be that "giraffes are so silly that they must have originated elsewhere." Or so it seems. Fast forward to season 3 where Amity, Gus, Willow, and Vee (all of them natives of the Boiling Isles themselves) visit a zoo in the human world and take a photo of a giraffe, causing it to show them its true face. Even they are terrified.
