Eldritch Abominations in Fan Fiction.
Avatar: The Last Airbender
- The World without the War has 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, escapes, the other three Beasts will awaken, they would destroy civilization. Because that's the only way they can communicate with humans.
- In the Alternate Universe Fic Embers, quite a few of the more dangerous spirits are either this or an Animalistic Abomination.
Codename: Kids Next Door
- Invoked/parodied in 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. Oh, and one of them wants to date Nigel Uno.
- Lost Tales of Fantasia has the inhabitants of Wonderland, which are described as demonic creatures of nightmares. Wonderland itself is an Eldritch Location that is said to be Hell. The two beings we see that come from it, Alice and the Headless Horseman, are definitely Humanoid Abominations. Chernabog is also hinted at.
- Children of an Elder God mixes Neon Genesis Evangelion with the Cthulhu Mythos. The Children have to fight the Elder Gods and the Great Old Ones, and every time they kill one of them, they absorb their power. At the end, Shinji, Asuka and their teammates have become Eldritch Abominations and leave human society forever because everyone is frightened of them.
- Child of the Storm mentions the Outsiders from The Dresden Files. It also has the Elder God of Chaos and Black Magic Chthon, who spends most of the book masterminding his return through the Darkhold, the Tome of Eldritch Lore, described as being indestructible and 'a brother to entropy'. His mere voice makes reality scream and when he finally succeeds, the presence of a mere fragment of him on the mortal plane starts twisting reality inside-out, and if he emerges in full, he'll destroy the universe.
- The N'Garai and the Mabdhara, Chthon's heralds and their generals, qualify as a smaller scale version of this, with the latter being able to manipulate chaos to disperse pretty much any magical attack thrown at them, to the point where one feels comfortable ignoring Wanda Maximoff of all people. She makes it regret that decision.
- Dormammu, Surtur, Shuma-Gorath, and Lucifer all qualify, being mentioned as problems that Doctor Strange has to deal with.
- The Endless qualify as a fairly benevolent (mostly) version of this; however, it must not be forgotten that these are indescribably ancient beings that date back to the very beginning of the universe, or may even predate it entirely, that appear differently to every single separate observer, can do with reality pretty much what they please, and operate on an entirely different moral framework even to gods, let alone mortals.
- The Phoenix a.k.a. Destruction is a particular example: on the physical plane, She has no specific form, unlike Her siblings, taking hosts, restoring or destroying worlds, making such decisions on an incomprehensible logic, being explicitly described by Loki as more of a force of nature than anything else. Loki describes Her as a being without any concept of collateral damage, restraint, or middle gears in general, taking hosts as a Morality Chain. Oh, and she can play with reality with consummate ease - when possessing Harry, instead of simply standing up, She rearranges reality so that he's stood up, in the exact same way that Chthon does several chapters later. Even a small fragment of her power isn't meant to touch the world in one place for very long, for fear of burning a hole in the universe and providing a beacon for yet more examples of this trope. More to the point, She's even more powerful than he is; when the Darkhold - semi-sentient utterly indestructible ultimate Tome of Eldritch Lore - senses a mere whisper of her power, it starts literally trembling in fear.
- And that's when she's in one of Her benevolent/justifiably outraged moods (what with having merged with Lily Potter, Harry's mother). The Dark Phoenix is described as all that amoral volatility combined with human darkness, and is even worse, something that Doctor Strange, who fights examples of this trope for a living, describes as 'a horror beyond words'.
- This description is entirely justified, since the last Dark Phoenix, Surtur, destroyed an entire galaxy before it was stopped, also creating the Great Dragons (think Smaug, but worse), transforming defectors into its seven 'Great Captains', each of which is at least a Physical God and an example in their own right (one of them is Jormungand, father of dragons, who even when relatively weak, was only beaten when Thor threw him into a neutron star), transforming the spirits of its dead enemies into Person of Mass Destruction scale minions, getting more powerful whenever it was fought... And even when it was defeated, even then, it was impossible to kill, so the Alliance against it had to empower a Skyfather level champion with a specially enchanted blade made of Uru and Vibranium, specifically designed to No-Sell its Phoenix fire, just to distract it for long enough for them to seal it away. And even then, they could only imprison it for a million years in a cosmic scale multi-dimensional magical prison that encompasses entire worlds (it's Yggdrasil), which simultaneously keeps it locked away, siphons off its power to strengthen the prison/empower the Warden, and which still occasionally becomes a Leaking Can of Evil.
- Last Child of Krypton: This story includes eldritch beings of both universes: the Angels (giant alien beings who display a myriad of shapes and defy the laws of physics) and the New Gods. Most prominently, evil god Darkseid.
- Superwomen of Eva 2: Lone Heir of Krypton: Asuka fights humongous alien monsters known as Angels, and during an arc story she also faces the New Gods of Apokolips.
- Thousand Shinji mixes Neon Genesis Evangelion with Warhammer 40,000. The Children become worshippers of the Chaos Gods and they slowly beging to change until they ascend and become the New Chaos Gods. At the very least they are more benevolent than their predecesors.
- In Buffy the Vampire Slayer/Supergirl crossover The Vampire of Steel, M'Nagaleh, a cosmic horror summoned by a mob of vampires checks most of Lovecraftian traits: Completely alien thought processes? Check. Humongous? Check. Gelatinous? Check. Terrifyingly powerful? Check. Tentacles? Double check. It's even called "a glob of whatever-it-was".
An aperture was opening in the very air above them, and something was tumbling out. Something glistening, gelatinous, tentacled, eyed, and alive. It settled around the towers, but there was more of it coming out.
- 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 Eldritch Abomination status.
- Personality Conflicts depicts the Green Ranger and Nyghtmayr as this.
- In the My Little Pony: Friendship Is Magic/Doctor Who crossover Time Lords and Terror, The Smooze, the infamous Blob Monster from the G1 theatrical movie, is re-imagined as the SMüz, an omnicidal cloud of 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 Class Z Event! The only way the non-Time Lord protagonists are able to withstand seeing the monstrosity with sanity intact is with the help of inverted perception filters. It doesn't help that the author can convincingly write in the Cosmic Horror Story style, with in-depth descriptions of the alien and often contradictory aspects of the abomination, nor that it was deliberately written to channel Sovereign.
- The Ranma ½/Sailor Moon fic The Dark Lords of Nerima 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. Subverted, Unit Zero is actually a clone of Sailor Moon. The sensed power is that of Serenity's bloodline, and the emptiness is due to the girl's lack of a Star Seed. The only cure for that is to rip out the original's Star Seed and put it in herself, which, thanks to Unit Zero's conditioning, will leave the power of the Silver Crystal in the hands of the antagonists. Whatever the case, she isn't even a Humanoid Abomination, and is most certainly a Woobie, Destroyer of Worlds.
- A more straight example comes in the form of the Nameless One, a malevolent entity that was sealed away by previous generations of Senshi, but can still manifest its power through use of minions that heed its call. It has enough power to break Sailor Moon's seal on the Dark Kingdom, and when it manages to open enough of a rift to attack directly, it takes Sailor Chibi-Moon, the rest of the Sailor Senshi, sans Saturn, the power of Helios and his sister Melinoe and power of all the dreams and nightmares of the human race channeled through the Golden Crystal to drive it back and seal the rift.
- In The Master of Death, Harry Potter and his companion both appear as Eldritch Abominations when they appear in the Dresden universe because according to his companion, the universe requires they leave behind their Shapes and borrow new ones from a place where nothing exists until they leave. In his words, "There's quite a lot that doesn't exist. We didn't exist until a moment ago." As a result, to Dresden, most of his encounters with Harry are distinctly unnerving, because he thinks (and is technically right) that this twinkly eyed old man is one of the most terrifying entities ever to cross the boundaries of reality. The facts that parts of Harry's magic are literally impossible by Dresden Files standards, and that he usually appears through a gigantic train that seems to happily park in midair, doesn't help. Then Dresden winds up literally having tea with Cthulhu.
- Computer viruses and malware manifest as such in The Infinite Loops. There's also the Hackers, which are inspired by Lovecraft. And then there's the viral composite consciousness that caused The Crash, an event which resulted in the total Ret Gone of a universe.
- The supercrossover military fanfiction The Terminators: Army of Legend features Archdemon Deitus the Lifehunter, the fallen, immortal son of fallen Archangels Messorem and Vitam, the literal incarnations of Death and Life respectively. The Lifehunter has many forms he can take, including projecting himself and his image to others, through dreams or a waking state, and he wields unimaginable power, even while bound to his throne in Purgatory through the mystical and incomprehensible Chains of Eternity. One of his favorite past times is tormenting mortals, angels, and demons alike, and he's strongly hinted to be the puppet master throughout the entire series. Even the common form he takes (and may be his true form if the appearance of his young son is any indicator) is that of a massive satyr with slick, oily-black tentacles sprouting from his body which he uses to sap the life force from his victims to feed his own immortality, turning them into grisly, dehydrated husks in the process, thus granting him his nickname.
- My Littly Pony/Minecraft Crossover, My Little Minecraft At The End gives us several examples. In order of increasing power and nastiness, they are:
- The Miner himself. He resembles nothing that the ponies have ever seen before, and his powers defy all the laws of nature as they understand them. They even speculate that he has to physically override the laws of nature surrounding their own world in order to use his powers on them, essentially rewriting pieces of their world to work by his own rules instead. Fortunately, he is more intent of keeping his head down and experiencing the sensations of the new dimension he finds himself in than causing any lasting harm.
- Brimstone, the Fallen King, is the disembodied consciousness of the former ruler of the Crafters, essentially an entire race of Minecraft players. Though lacking a physical form, he can Body Surf seemingly at will, inflict various mental tricks including memory alteration, Grand Theft Me, extremely vivid hallucinations, crippling fear, and Mind Rape, enhance ponies to super-equine levels of strength, speed, and perception, or apparently disintegrate them outright. Fortunately, he stands decidedly against the story's Bid Bad (see below). Unfortunately, his mental state can be accurately described as "a disembodied mass of pure hate and rage" directed towards said Big Bad, and he accordingly does not play well with others.
- Herobrine. The Void Fog found near the bottoms of Minecraft worlds is apparently an extension of his essence, and his first act upon manifesting in Equestria is to use it to spawn the Wither. He can mask himself from mortal detection, create powerful storms at will, enable hostile Mobs to spawn from any dark space over a large area ( at least the size of Ponyville and the nearby Guard camp), created inter-dimensional portals wherever he wants and easily gain the upper hand against Princess Luna inside of a dreamscape. He seeks to use the Elements to unseal the rest of his power, and will then likely destroy all civilization on the planet.
- Era'Doth. It was the source of the Crafters their powers, and later annihilated them entirely, apparently only sparing what was left of their king because it was unaware that there even was anything left. Sometime afterwards, it was somehow torn to pieces, and those pieces were bound in chains of magical light and sealed in extra-dimensional prisons. During the events of the story, its severed head escapes, still wrapped in the chain, and takes the name Herobrine.
- Guardians, Wizards, and Kung-Fu Fighters has the Cavalcade of Horrors, the entities living in the depths of the Shadow Realm, which are described as being masses of claws and tentacles, with hides that shift between feathers and scales, and too many eyes. And then there's whatever the hell lives below them at the very bottom of the Shadow Realm, which they serve and is described as being god-like.
- The Bridge:
- Grand King Ghidorah is presented as one. He only looks like a three-headed golden dragon, but is something so alien in biology that calling him one is a serious understatement. He's also so impossibly ancient that he was a teenager when he and his brother wiped out the dinosaurs.
- The Nexuses of Magic Bagan, Harmony, and Grogar are presented this, with Word of God constantly stressing that while they resemble a dragon, a pony, and a goat, they're not. They're just primordial entities that look like them. They're also so immensely powerful that Grand King Ghidorah is zero match for any of them, even when they're only at 30 percent of their full power and a rampage by one of them is perceived by modern humans as having been a natural disaster as they simply couldn't comprehend that something that strong could actually exist. Thankfully, Harmony is completely benevolent and opposing the other two.
- Celestia and Luna could be considered lower tier ones, as they're actually pieces of Harmony's power given life.
- Harry Potter in Master of Death and What it Means only appears human because he chooses to. When the Avengers catch a glimpse of his form (despite being warned not to look), it's described as impossibly large and infinite, simultaneously the absence of light and the radiance of a thousand suns, sometimes winged and sometimes horned, with the stardust of universes dripping between it's teeth.
- Biomass Effect: in adition to the things we see in Mass Effect and Prototype we have the things created by the "Children of Saleon" virus created by Dr. Heart, for reference, this is a virus that is both too spicy for Blacklight to consume, can incorporate inorganic matter into its form and, according to Blacklight which can rewrite its DNA however it wants, makes zero biological sense, examples include:
- Hearts mutant Varren, one of which devours the leftovers from his experiments by vomiting its stomach inside out, wrapping it around its food and using mucus to make it stick before pulling it back in, another, one Heart uses as a Lab Pet gets killed killed by Blacklight along with the others only to come back as an even bigger, more monstrous version when one of its claws gets chopped off via the door to Hearts escape pod. Later, Heart decides to improve it further by giving it cybernetic implants.
- Later, when Heart finally realizes he went too far. he tries to destroy his lab via a nuke. When a group of mercs he hired earlier check to see what happened they find a radioactive monster made from Heart, his pet cyber-varren and the rest of the biomass in the lab.
- The Mother Husk, an amphibious, huskified, Kaiju sized amalgam of Saleon virus infused biomass, spaceship wreckage and anything else it assimilated after crash landing in Khar'shans oceans. When Blacklight sends its own giant biomass creature to stop it, the Batarian navy watching describe it as something between a Kaiju Battle and two cosmic horrors duking it out.
- Later the Batarians end up trying to nuke the Mother Husk, not only does that make it more powerful, it splatters most of their equipment with Saleon virus biomass causing their vehicles to turn into mechanical abominations.
- In the Magical Girl Crisis Crossover Shattered Skies: The Morning Lights, Joker unleashes "the entity", an enormous, unkillable Space Time Eater from far beyond the boundaries of the story's Multiverse. Within seconds, "the entity" completely annihilates every post-Go Princess Precure continuity, and devours the futures of all the rest, causing the surviving timelines to collapse together in a catastrophic Time Crash.
- Citadel of the Heart:
- Truth and Ideals has the infamous Chargestone Cave arc, a plot point planned from the very conception of the story, ending with the climatic showdown against MissingNo.. Not any of the versions it appears as in Gen I, mind you, but rather, all five versions combined into one singular form of madness.
- For the continuity as a whole, we have Darigus and his primordial father known as Zenith.
- White Rabbit truly takes the cake by not having the cosmic element as the two above, but also has a subtlety they lack; White Rabbit normally takes on a variation of its regular form, ranging from small and diminutive in stature, to large and lanky. Then there's the appearance it takes when it completely begins to suffer an overload, in which its body tears apart, its head splits clean open and reveals a sphere capable of firing a laser beam, and its wings having completely melted off and reattached as veins. White Rabbit's more Earthly origins leads one to ask many things, but nobody is quite sure as to why exactly White Rabbit's left arm functions as an esophagus and jaws for fingers.
- The Last Daughter has the Endbringers, sentient mountains of organic tissue surrounding a core.
The Fairly OddParents!
- In Never Had A Friend Like Me, it turns out that Bob the boil on Elmer's face is one. He is trapped in a another universe, one where the rules are vastly different, and can only have limited contact with the main universe while in that state. Then Timmy makes just the wrong wish and unleashes Bob from the boil, which leads to reality warping around him in a growing orb of influence at his mere presence. And he fully intends to take over and remake the world into how he'd like it.
- The fan mod Blue Planet applies this to the Shivans (who were merely Starfish Aliens in the canon games... as far as anyone knows). Shivans in the BP-verse are 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 Techno Babble, 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.
Mobile Suit Gundam: Iron-Blooded Orphans
- Deathly Hallowed portrays Death as this. Lily summons it to 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 mind-raping form of telepathy or Black Speech.
- Perhaps worse are all the Eldritch Abominations that seem to be after both Harry and Death.
- Rabbit in Lily and the Art of Being Sisyphus. Of course it's not really a rabbit but some cosmic horror from beyond reality that Lily has forced into the shape of a rabbit when she pulls it out of a hat and she fears that if she leaves it unattended, it will eat Scotland.
- The Perennials in King Of Kings Ruling Over Rulers. A species of ultra-dimensional beings which are the physical and metaphysical embodiments of what creation itself acknowledges as "true concepts". It is impossible to kill a Perennial, and the first attempt to do so both failed and succeeded. The Sacred Twelve (aka Progenitors) are known for assuming...uncanny shapes.
- The being known as Ayavan is regarded as this by the Perennials themselves, to the point where they waged an entire war in an attempt at destroying him. They failed.
- Mort in Monsterous is a being of smoke and shadows that can grow a hardened spiked carapace in an instant, moves on four legs or two as it feels appropriate, has a tail that ends in three prehensile claws, and lacks any sort of face. On top of this it's shown to change size from a large horse to an Oliphant and anywhere in between along with casually changing it's skeletal structure (it once "flexed the bones" of its skull out of boredom) and is capable of using magic. Oh and it used to Harry Potter.
- This fanfic features an entity called Shlog'ec'mer, a massive tentacled blob that is capable of disguising its form (in the story's present, it takes on the appearance of a carnival's haunted house attraction), and which claims to be from beyond the universe as it's understood by three-dimensional beings. It travels between worlds, ensnaring victims who it places in Lotus Eater Machines that trap them in their worst nightmares so that it can feed on their fear. It does this to Gaz, Zim, and Dib, but when it tries on GIR, it ends up going insane and dying.
Jackie Chan Adventures
- Webwork has the entities that sit in control of the Balance Between Good and Evil, 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.
- In Ages of Shadow, Jade evolves into one over the course of the countless centuries she spends locked away in the Shadow Realm. Having already become an unstoppable, immortal Physical God (which is what required her being sealed away in the first place), she slowly warps her body into a new form in order to better adapt to the nature of the Realm (and just as something to do) — she gives herself a tail, turns her now pointless legs into extra arms, and turns her hair into tentacles, among other things. And then she encounters an alternate Earth, where she gets her own cult, which worships her for thousands of years and seeks to unleash her to conquer the world. All this combined with her isolation-induced madness giving her borderline Blue and Orange Morality, and she's really hitting all the points of this trope.
Katekyō Hitman Reborn!
- Dead-Eyed Tsuna has the eldritch abomination be the protagonist Tsuna himself by having ash leak out of his wounds and heal them.
The Legend of Zelda
- The expanded Fan Verse of Paris Burning includes several of these, the most prominent of which resides under the Antarctic ice and seems to be implementing an Assimilation Plot. Others include the broken giant that resides in the Grand Canyon, the northern ice 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 it is the runt of the litter.
- The Reapers were this already, but in Spectre Sovereign has taken it to new heights, all but mind raping Shepard on more than one occasion.
- The Reapers once again, in Mass Effect: End of Days, where we get to observe the thoughts of the Reaper-larvae from the Collector base as it gains consciousness. While the Reapers have yet to make a proper appearance, they are shaping up to becoming fullblown Eldritch.
It was magnificent. The Entity moved towards the Light, and the Light grew ever larger, blowing away the darkness. A shape took form, and It saw Its new form, and Its previous world clearly. As starlight reflected on the waters' surface. The stars' light will not be extinguished. As long as They exist in the sky, starlight will remain on the water...
...And this is a thing which already was.
- The Leviathans in Of Sheep And Battle Chicken are so far beyond other life forms that they barely understand it, and even a single elder Leviathan is so powerful that the Reapers think committing hundreds or thousands of themselves against a single 'Old One' is an entirely appropriate response... and the odds of a Pyrrhic victory are all too likely.
My Little Pony: Friendship Is Magic
- Destiny Is A Hazy Thing: The Bijuu's Animalistic Abomination forms were actually forced upon them by the Rikudo Sennin; their real forms are far more alien. Shukaku's true form, the only one seen so far, most closely resembles a massive sandstorm filled with lightning.
Neon Genesis Evangelion
- A Crown of Stars: Daniel and their family's true shapes are pretty incomprehensible and confusing to human senses. Even post-fusion with Lilith Rei Ayanami gets disturbed by Daniel.
- The Child of Love:
- In chapter 3 a fanmade Angel shows up. It looks like a thin feather with a sphere on the top. An examination reveals that it might seem light but it weighs 3,000,000,000 tons.
- In chapter 7 another fanmade Angel shows up. It looked like a winged Evangelion unit.
- Doing It Right This Time: After returning to the past, Shinji, Asuka and Rei have to fight the giant alien Angels... again. The "alien goddess in the basement who may or may not be God" Lilith is also mentioned.
- HERZ: In addition to the Angels the cast defeated in the backstory, the alien deities and Seeds of Life Adam and Lilith whom Rei absorbed and the MP-Evas, several countries try to create their own Evangelion, and sometimes they spawn shapeless, massive monsters with too many limbs and heads sprouting from strange places. SEELE also created a new batch of MP-Evas to fight the main characters.
- In Neon Genesis Evangelion: Genocide new Angels appear, though they are in reality artificially created from the flesh of a rogue Evangelion unity, made by an advanced computer program, which has the ability to manipulate the DNA found in Evas on a molecular level. One of them is a massive inky blob that turns into a sphere of black energy.
- Nobody Dies: Rei Ayanami is this. 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 whatever the hell 02-Ef A9 becomes still count.
- Higher Learning: The giant aliens Angels of the original series also show up here. Special mention goes to Bardiel, since he was defeated in a very different way, and he was unable to hijack Unit-03. Its true body resembled a black, amorphous stormcloud.
- Once More with Feeling sees Shinji having to fight the Angel again... and unfortunately they seem more powerful than they were in the original timeline.
- The One I Love Is: Nearly all of the Angels are true to their canon selves, except for Tabris. He is a her in this story. Adam — the father of the Angels — and Lilith — mother of all life on Earth — also show up. In addition to them Gendo manages to merge with both Adam and Lilith at the end of the story.
- ''Persona 4: Five Years Later'' has 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.
- Latias' Journey is chock full of Abominations all led and mostly created by the Big Bad Deoxys (who is one himself), being 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 she is Latias' mutated mother.
- The sequel, Brave New World, has abominations like Yamatorochi and Jovi after Tarantulas's experiments. Giratina is still an Eldritch, and other beasties like the Gaiavore are sure to show up later.
- Leviathan also returns as a creation of the Ruler of Evil used during the Crisis Wars.
- Arackaiser merges the legendary birds into Maelstrom during the Battle of Shimmer Desert. He does the same thing to the legendary beasts, merging them into Cerberus, who is easily separated by Leo.
- Pokémon Mystery Dungeon Journal has Heath, the main character, being revealed as one of these midway through the story. It's a shock even to him.
- The Sun Soul has its depiction of Zapdos, who is somewhere between this and Olympus Mons.
- In The Power That's Inside, Meowth becomes The Missing No. for a moment after having his energy harvested.
- In Pokémon Reset Bloodlines, there's MissingNo itself, originated as a remnant of the previous timeline. It's apparently been known for several demonic names, and takes great pleasure in tormenting Ash about the things that have happened or will happen to his friends, knowing that he can't do anything about it.
- The various Legendaries in Traveler aren't so much powerful Pokémon as they are gods whose mere presence can wipe out entire regions. The Legendary Birds in particular have a possibly true form that turns them into masses of their element in the rough shape of a bird, such as Moltres being a towering inferno that resembles a bird with molten lava for legs. The massive storm the Shamouti birds caused that would wipe out the world? That was nothing but a territorial display between the three; and Lugia confesses that each is only a third as strong as they used to be.
Puella Magi Madoka Magica
- Esurientes assume the place of Witches in the Madoka fanfic Cibus Esculentus Madoka Magica. Originating as humans overloaded with negativity, they manifest as all manner of predatory beasts. They maintain barriers to avoid detection by normal humans in order to eat without disruption, and once they eat enough, they then burst into spawn.
Randy Cunningham: 9th Grade Ninja
- Enter Ken Finlayson features Moloch the Death Raptor, one of the animalistic variety, who basically comes across as the Owlman from Lost Tapes transplanted into a Randy Cunningham fan fiction.
- Celestial Warrior Moon:
- The Entity behind the Dark Kingdom, who is really Queen Metalia. The Entity arrived in the galaxy during the Silver Millennium and being a Galactic Conquerer. Myddin's description of her is nothing short of Lovecraftian, and Ami flat out compares the Entity to Lovecraft's work.
Myddin: Something dark entered our galaxy. What It was, is still unclear. Its intentions, however, could not be less ambiguous. It was a harbinger of chaos and destruction, reaping death wherever it went. My people were quick to intercept Its path, and It did not take kindly to us. I accompanied them to serve as witness to the event. I could never properly describe the beast before us. Envision viewing something through the extremities of your peripheral vision. It appeared as blurred, soft, and weak. No hard angles or sharp edges. Its true form remained hidden to me, a shapeless form concealed under a cloak of hollowness. In a word: imprecise.
- The Slender Man also shows up, named the Black King here.
The Slender Man Mythos
Sonic the Hedgehog
- The Forceless Collective in the 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 The Force and are implied not to be natural forms of life. Their primary symbiotic form, the Black Matter, is not unlike Mnggal-Mnggal in the 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, 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 mutated in the process of symbiosis, and some of them, particularly some of the Archfiends, qualify as abominations themselves.
Super Mario Bros.
- As revealed in Movie 1 of Clash of the Elements, 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...
Team Fortress 2
- In the Team Fortress 2 fandom, use of Garry's Mod 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 Slender Man proportions, converts other Scouts into its own distorted likeness, and can make Your Head Asplode through eye contact. The Vagineer is the original, and probably the worst, speaking only backwards and with powers ranging from using body parts of others to repair itself to corrupting others by its mere presence.
- The Doctor Will See You Now: The hints of the darkness that have been given titles (the Voice, Something beyond humanity, #409) show a complete disregard for humanity, even if their actions and presence harm them. The Voice either creates or allows vividly real visions of truly horrifying images of teenagers gruesome deaths, complete with feeling the pain of a violent death. Even when saving her life, #409 does so by forcing Gwen to endure a painful ordeal while not showing even a minuscule amount of guilt. They dont seem to hate humanity, but they dont care about it either. Thats in some ways more horrifying, seeing how they alter reality.
- Imperfect Metamorphosis:
- Rumia's Super-Powered Evil Side, otherwise known as the Shadow Youkai, is Walking Wasteland personified; a single touch can result in death, and even the most powerful denizens of Gensokyo are not completely immune from its corruptive power. Near-impossible to kill, its vanquishers could only seal it in a weakened from and strip it of its memories, but that didn't last long. Later events reveal it's a Fallen Angel.
- Yuuka Kazami is intensely feared by everyone, Yukari's powers are ineffective against her, no-one has the slightest clue what she is, and she laughs off everything thrown at her. Even after assembling a team of godly powerhouses equipped with the most potent weapons in Yukari's arsenal the battle against her swiftly goes tits up, in the process revealing her nature as a weakened Outer God.
- Yukari Yakumo's depiction in Maiden's Illusionary Funeral. She doesn't project her gaps, she is her gaps, a formless mass of darkness and eyes masquerading as a human woman. She's so powerful that nothing in the story can stop her; getting bisected is less than an inconvenience, and she's the only one that can get close to Yuyuko without being killed, suggesting that she's beyond death.
- The Plot Hole from PRIMARCHS. A living gestalt of all the plot holes accumulated in fiction that wants to eat the universe until only it remains.
- Warhammer 40,000 has no shortage of this trope, but The Shape of the Nightmare to Come 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 God-Emperor made manifest in the Warp, the 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 Ultimate Evil at the (maybe) heart of the Warp. To Go Mad from the Revelation is the least terrible thing that can happen to you if you learn anything about it beyond its name.
- The Age of Dusk, sequel to Nightmare to Come, 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. Word of God says the chaos gods themselves are only aspects of the Nex.
- Ripples has A'lek'hol'an, the entity that Will/Van makes a deal with during a near-death experience. The last of The Old Gods, Will isn't able to even remotely grasp his true form on the spirit realm, and in Meridian he takes the form of a sentient swamp, which is where the cult that worships him is located. He's also insanely powerful, as he's able to completely change Will's body and enhance her powers, seemingly at a whim.
- In 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. It is Taylor's true form.
Yu Gi Oh5ds
- My Dark King has the King of the Underworld, who takes it to the logical extreme and is worse than in the anime. It can spawn lesser Earthbound Gods from its body, and according to Judai, it arrived on Earth 65 million years ago. It gets into a fight with the Sengenma, as well.
- It is actually part of an entire species of extraterrestrial abominations, which Judai calls Coisichean Dorchadas (Gaelic for "darkness walkers"). Such members of the race include Darkness, Zorc, and the Great Leviathan.
