Eldritch Abomination/Video Games




 * Skullgirls has Double, a shape-shifting creature that often appears as a digusting lump of flesh, bone, and teeth vaguely shaped like a woman. She usually hides her true nature by taking the form of a smiling nun. When Double enters the battlefield, the nun opens her mouth five feet wide, and basically turns inside out through the hole, revealing Double's true, shapeless, disgusting form.
 * Zophar, from Lunar: Eternal Blue. A colossal, floating monolith, whose body is a black tower extending from the heavens, leading down into a face resembling an Olmec Indian sculpture with glowing red eyes and skeletal dragons for arms. He feeds off the hatred and evil in the hearts of humanity, feeds these emotions in order to gain strength from it, and, when he's grown powerful enough, physically manidfests in the form described above. His goal? To gain the power of creation from the goddess Althena, and remake the entire universe as he sees fit. And if his fortress is any indicator, it's going to be very icky.
 * Of course, he's substantially less scary-looking when he does get the power of Althena. His aims are still plenty terrifying, though.
 * League of Legends has quite a few of these as playable characters. This includes Cho'Gath, a demon, Fiddlesticks, an extraplanar crow god, Kog'Maw, an acid-spewing alien, Xerath, a mage-turned-Energy Being of terrifying power and virtually inhuman morality, and Nocturne, a nightmare-dwelling monstrosity who murdered people in their dreams just for kicks before being forcibly pulled into the land of the awake. Kassadin and Malzahar, meanwhile, derive their powers from the Void, though their motives for using said powers are radically different.
 * Big Bad Bacterion, The Dragon Dr. Venom, Dragon Ascendant Gofer, and Zelos the Planet Eater from Gradius are all Eldritch Abominations with the ability of regeneration and cell division.
 * Dr. Venom wasn't always like this: he was once a Wreekian, a primitive humanoid race with powers that can be used as energy. But then, in 6644, a Bacterian fleet (headed by the future version of Dr. Venom and Gofer) attacked Gradius, which nearly wiped out all of the Wreek. The Gradian government didn't give a damn about the surviving Wreekians, which angered Venom enough to plan a (failed) coup and end up becoming an ally of the Bacterian to get his revenge on Gradius.
 * The final boss in Gradius 3 is one of these. He seems to be the whole level and is a bunch of heads and eyes in a giant mass of flesh.
 * The Lambent from the Gears of War series, especially the Lambent Brumak and Drudges. If Drudges take too much damage but do not die, they will hideously mutate into three different forms: (.
 * The Crawler Zombie from the Nazi Zombies mode of Call of Duty' has an over-sized angler fish-like mouth as the only prominent feature on the face.
 * Lavos from Chrono Trigger—a horror from space that descended to Earth when it was young, and slept and ate until it was awakened to destroy it in 1999. While Lavos' initial form is just a giant magical space tick, it evolves into full-fledged Eldritch Abomination in Chrono Cross, after it merged with Schala and became the Time Devourer. The Time Devourer lurks at the Darkness Beyond Time, where cancelled timelines go, growing in power and preparing to destroy all of time and space. Even worse, it can't be killed—no matter how thoroughly you destroy it, because of the infinite nature of the timelines there'll always be a timeline where you didn't destroy it, and it'll pull itself out of there and return to the Darkness.
 * We see the Time Devourer in its full hideous glory in the Bonus Dungeon of the DS remake, there known as "Dream Devourer". After you "win", The Battle Didn't Count since it just absorbs a self from another reality where it doesn't die. and the new ending implies the beginning of the massive Xanatos Roulette that is Chrono Cross.
 * Lavos is also explicitly stated to be just one member of an entire species. Multiple times in the end game, you fight "Lavos Spawn", Lavos' children, with the clear implication that they're how Lavos began its own life..
 * Even better, Lavos is summonable through occult ritual, and is itself a source of magical power.
 * Undertale gives us Omega Flowey and the Amalgamates.
 * The Primagen in Turok 2, who threatens to break out of his prison and unravel the fabric of the universe. There's also Oblivion, another Abomination who is the Big Bad of the third game.
 * The Androsynth disappeared before the beginning of Star Control II, and their region of space is now occupied by the Orz. Trying to put together an accurate assessment of what happened on their homeworld results in the scientist who read about the Androsynth's IDF research going insane and being attacked by invisible creatures. It's not exactly clear what went down, but the Arilou put it best: "You do not wish to be seen. The Androsynth were seen. There are no more Androsynth anymore. Only Orz."
 * This is an especially subtle example: early on, the Orz seem comical, with their round bird-beaked bodies, their nearly-untranslatable speech and their silly voices. But if you ask the Orz about the Androsynth, they attack and take no prisoners. Also note that "going insane and being attacked by invisible creatures" is a good description of what happened to Abdul Al-Hazred, writer of the Necronomicon in H.P. Lovecraft's works.
 * As if the Orz needed any more creepy stuff said about them, It Got Worse: According to developers, Orz as the captain sees them are actually a projection of some higher-dimensional being's fingers. At one point, you can also find them above what used to be the Taalo homeworld. Now, for context, the Taalo were exterminated several thousand years ago. The Orz claim to be currently interacting with the dead Taalo, chasing them and describing it as excellent fun. They also imply that this will be humanity's eventual fate if they continue to be good campers.
 * In Quasi-Space, part of the background music is quite obviously something screaming. It doesn't ever actually appear, which somehow just makes it worse.
 * Star Control 3 has many flaws (including ruining the Orz from the second game), but the Eternal Ones are completely lovecraftian: they're invincible, and feed on "sentience", so they wait for advanced civilizations to develop and then come and harvest them.
 * In MOTHER, Giygas was just an alien. A very angry Grey alien who tried being human for a while, but was upset when humanity took advantage of his knowledge. In the sequel EarthBound however, Giygas has become something far more horrible. Mindless, he exists in the future and the past, and has no physical form. He's practically Azathoth with less tentacles, and became the Trope Namer for one of the main characteristics of Eldritch Abominations, You Cannot Grasp the True Form.
 * Shadow of the Comet, Prisoner of Ice and the better-known Alone in the Dark by Infogames are all in the same Cthulhu Mythos-haunted world, with several direct Lovecraftian references including the Necronomicon and De Vermis Mysteriis. The name of the mansion from the first Alone In The Dark, Derceto, is revealed in-game to be an alias of Shub-Niggurath, the Mythos' equivalent of a fertility deity... Oh, and there's a Cthonian in the basement.
 * Shub-Niggurath's other title is "The Black Goat of the Woods with a thousand young". Those three-legged, tree-sized monsters in the picture at the top of the page? Her children. And of course Mommy is watching over the whole thing.
 * Zelda francise has various bosses that fit this bill, many of which serve as Big Bads:
 * Bongo Bongo from The Legend of Zelda: Ocarina of Time, is a giant, vaguely humanoid phantom with disembodied, floating Giant Hands of Doom. Its "face" consists of a singular red eye.
 * The Legend of Zelda: Majora's Mask has the titular antagonist, a seemingly-sentient mask that revels in destruction..
 * The Shadow Nightmares from The Legend of Zelda: Link's Awakening and its Updated Rereleases for the Game Boy Color and Nintendo Switch. They are amorphous blobs of darkness that take on various shadowy forms, some of them familiar - their last form, Dethl, has a single eye and spike-tipped arms that it will try to bludgeon Link with..
 * Bellum, the Big Bad of The Legend of Zelda: Phantom Hourglass, is a large squid-like creature adorned with eyes, including one in a mouth-like cavity and one on each tentacle. It's actively malevolent and obsessed with absorbing Life Force.
 * In The Legend of Zelda: The Minish Cap, Vaati goes One-Winged Angel and becomes this after . This also applies to his appearances in Four Swords and Four Swords Adventures (which chronologically take place after), where he is always depicted in his one-eyed form.
 * The Imprisoned in Skyward Sword.
 * Most games in the Shin Megami Tensei series and its spin-offs will let you control or fight with at least a few dozens of these - some of the designs of demons are themselves Eldritch, if they weren't already. Taken a gander at the Mythology and Religion sub-page yet? Some of those handsome fellas (most of them, really) found their way to these games. Whole paragraphs could be devoted at an attempt to explain as to what Satan looks like.
 * Now, a simple question, just so you can understand the sheer scope of just how alien the demons are: how exactly is a sentient entity made of ice crystals capable of forming a very reasonable facsimile of the human form?
 * Notably in Strange Journey, all demons appear as shapeless balls of static when you first encounter them, only revealing their form once you kill one. The only exceptions are bosses and demons that actually want you to see them..
 * Devil Survivor 2 has The Septentriones. Considering the likely inspiration for the fellas, not really surprising.
 * Lovecraftian deity Nyarlathotep is the villain of Persona 2, depicted in the page image, and receives bonus points for . Unfortunately, among the many avatars it chose to screw with the heroes, its most prominent one meant half the game was not released outside Japan until 2011's PSP remake... wherein he was given sunglasses to at least mask his appearance a little.
 * Persona 2: Eternal Punishment included Great Old One Hastur, the Byakhees, and Elder God Nodens as summonable Personae.
 * In the PlayStation Portable release, Persona 2: Innocent Sin,.
 * Persona 3 has Nyx, an Anthropomorphic Personification of Death, as its Big Bad; SEES fights it to assert themselves as living beings (and on the slimmest of chances they might even win). It even subverts the traditional Did You Just Punch Out Cthulhu? ending for video games featuring them: being Death itself, it can never be vanquished, and allows itself to be "beaten" as a courtesy to let the heroes live to their fullest, then shrugs off the defeat and continues to bring about The End of the World as We Know It. Ultimately, this fate is only averted when.
 * For an extra dash of Nightmare Fuel... the body that SEES tried and failed to defeat was only Nyx's Avatar..
 * In the new chapter, Persona 3: FES, the team discovers Erebus (Nyx's husband and brother in Greek myth). Aigis and company learn that not only manifested the Abyss of Time, but also helped fuel Erebus, the Anthropomorphic Personification of nihilism and sorrow in human hearts. This "nihilism avatar" was the real problem, not Nyx—Nyx existed long before humanity ever awoke, and by itself was a completely neutral force; it was only when the self-destructive thoughts in Humanity hit a critical threshold that they coalesced into the decidedly unfriendly Erebus, who seeks to absorb Nyx's power and bring about The End of the World as We Know It. . The party fights Erebus in a final battle, and learns that.
 * In Persona 4, many a thing from beyond the TV screen more than fits the bill, with a small caveat:.
 * The Phantasy Star series has Dark Force and.
 * Despite its cute and fluffy aesthetics, the Kirby franchise is famous for its many genuinely creepy Lovecraftian horrors that are often pitted against everyone's favorite super-tough pink puff.
 * Most Kirby final bosses are at least somewhat Eldritch. Nightmare is the manifestation of everyone's bad dreams, Dark Mind from The Amazing Mirror is an evil mirror demon, and Dark Nebula from Squeak Squad is a sleeping Eldritch Abomination said to be the Lord of the Underworld itself. Also, all of these beings are heavily hinted to have some kind of connection to Zero/Dark Matter...
 * Dark Matter is an immensely powerful Hive Mind formed by a swarm of shadowy eyeball creatures that can possess any living beings they come into contact with, as well as corrupt entire planets into eldritch hellscapes choked by darkness. Further, judging by how often it's reappeared, it appears to be impossible to permanently destroy, and can only be temporarily defeated. It's even creepier when considering the setting. Thankfully, it's also far more defeatable than most major abominations, but you usually need some kind of special weapon to do so - it's so strong that.
 * 0 (Zero) is the "heart" of Dark Matter, essentially a giant bloody eyeball in a white sphere that fights by spraying its own blood at Kirby before tearing its eyeball from its body in a last ditch effort to kill him. It returned as 02 in Kirby 64: The Crystal Shards, looking like a nightmarish angel complete with wings and halo while still bleeding from its eye.
 * To a lesser extent, Zero/02's chief servant/decoy/imperfect form Miracle Matter has the same red eyeballs/simplistic white body aesthetic... but it looks less like a giant eye and more like a multi-sided die covered in eyeballs, and can transform into seven different bizarre-looking forms over the course of its boss fight. Unless you use attacks that correspond with its current form, you're not going to hurt it, and its base form is immune to all damage. And unlike any other form of Dark Matter that have some kind of vague explanation as to what they even are, there's nothing explaining Miracle Matter, which might just make it the most unsettling abomination of the bunch.
 * Kirby's friend Gooey is said to be an offshoot of Dark Matter, but is fortunately kind, goofy, and cute instead of horrifying. But during the fight against Zero in Dream Land 3, he transforms into something that looks closer to his brethren, showing that he's still in touch with his eldritch roots.
 * Clockwork Stars like Nova are planet-sized supercomputers that can warp space, time, and even reality itself to grant wishes to those who seek them out. And if  is of any indication, they can affect people's minds to the point of wiping memories, causing batshit insanity, and ultimately . While just as beatable as Dark Matter, they're also incredibly powerful, with  itself constantly teleporting in and out of reality and summoning large, surreal objects from another dimension during its boss fight.
 * Later games would portray recurring boss Kracko as this, at least from a lore standpoint. In terms of power and appearance he isn't anything too special - just a living cloud with an eyeball and spikes that can shoot lightning, rain, and laser beams. But he's an immortal beast that's been around since the dawn of time and is impossible to truly kill since the presence of clouds anywhere will allow him to revive himself. And by anywhere we mean anywhere: he can rematerialize on different planets and even other dimensions entirely.
 * Marx seems to become one after making his wish upon Nova. He spontaneously grows plants made entirely out of spikes, can generate knives from nowhere, and can rip himself in half to create a hole to a dimension made entirely out of pain. He gets even freakier in Super Smash Bros. Ultimate, where he can attack by turning his eyeballs into large shadowy blobs and siccing them on you, turn them into uncomfortably gigantic multi-pupiled laser guns, and sprout a complex web of tendrils that look disturbingly like veins or even blood vessels.
 * Kirby Star Allies would go on to give us the series' Most Triumphant Example: Void Termina, . The implications are definitely unnerving to say the least.
 * Kirby's proposed origin in the anime series Kirby: Right Back at Ya! more or less posits that he himself is an Eldritch Abomination that went good, which explains a lot. While this is an Alternate Continuity, the games would later hint that this is the case for the canonical Kirby. After all, he's ridiculously adaptive to all kinds of elements and weapons, can absorb and eat ridiculous amounts of matter in way that almost suggests that he has a literal Black Hole Belly, regularly fights godlike beings without breaking a sweat, and is even stated at different times to have unlimited power... or almost unlimited power..
 * Yuris from Tales of Rebirth. It's the physical manifestation of all of the negative emotions produced by the Huma and Gajuma after they're subjected to a Hate Plague, and has a rather indescribable appearance.
 * Tales of Vesperia has the Adephagos, A cookie to those who get the aesop.
 * The eponymous being from Chzo Mythos. A pain elemental who absorbed all its rivals, to the point where Chzo became a literal mountain of flesh that took over a sizable portion of the Ethereal Realm. A whole lot of events (that it could plan out ahead of time, thanks to it being in every possible time) and manipulations later, Chzo had a Religion of Evil on his side, a practically invincible right-hand-man, and Of course, we'd be all boned, had everyone not been.
 * Shadow Hearts is filled with these things. The Final Boss of the first game, Meta-God, . Covenant sets up Amon, one of Yuri's strongest Fusions from the first game, as part of a triumvirate of eldritch horrors, opposed and matched by Asmodeus and Astaroth.
 * Eternal Darkness: Sanity's Requiem takes one of the most interesting twists, as He's ultimately responsible for the main character's, and he's probably the only abomination even close to being good. Ever.
 * Denis Dyack, who founded Silicon Knights, the company behind Eternal Darkness, confirmed in an interview that yellow is definitely the colour of a fifth Ancient, supposedly.
 * In Drakengard, The World Is Always Doomed because the gods are not just evil, but also composed entirely of Eldritch Abominations. There are not slithering masses of tentacles that cause insanity by their very sight, but something very morbid.
 * And they're not just restricted to one dimension either! Their very presence in Shinjuku in Ending E causes such horrifying destruction to that world that humanity is driven to near-extinction, AKA the world of NieR. Which itself has more than its share of abominations as a result.
 * What Caim's sister comes back as in Ending B probably counts as well.
 * Warcraft 3 introduced a faction of vaguely Lovecraftian entities, the Faceless, presided over by a stock Eldritch Abomination called the Forgotten One. They were pretty easy to kill, though.
 * Warcraft also features the Old Gods (of which the Faceless are servants), which are basically Shout Outs to Lovecraftian entities. They are behind some of the truly nastier fellows who originated in Azeroth, such as corrupting Neltharion into Deathwing along with his entire dragonflight, corrupting Queen Azshara, the most powerful Night Elf sorceress, and creating the Naga, the silithid, the qiraji, and the nerubians. They're also the (partial) creators of Humans, some Giants, Dwarves, Gnomes and Troggs by use of their parasitic weapon, the Curse of Flesh, designed to make its targets more like them and less like the original seed races.
 * One Old God, C'thun, has, however, been killed by mortals (he was a raid boss). However, he had gotten his ass kicked by the godlike Titans so badly that they thought he was dead, so the players face him with only a fraction of his full power. Apparently, the remaining Old Gods pulled the fun trick of tying their existence to Azeroth, meaning that if they die, they take Azeroth down with them.
 * There is the question of whether they can even be truly killed. They are said to exist "outside the cycle" of life and death. And even though C'thun is technically dead, it was still able to mutate and transform Cho'Gall into a monstrosity.
 * The Faceless return in World of Warcraft: Wrath of the Lich King in the form of three Forgotten Ones and Herald Volazj, who are very Lovecraftian in appearance. The Herald periodically causes the player characters to go insane and fight one another. The power behind the Faceless, not to mention all sorts of other weirdness in Northrend, seems to be an Old God named Yogg-Saron (not to be confused with Yog'Sothoth, of course). Just Yogg-Saron's existence beneath the lands drove creatures to madness and its very blood is forged in to equipment for arming the armies of undead in Northrend.
 * Yogg-Saron was featured in a content patch. True to trope, he is able to drive characters insane and make the entire raid hallucinate about past events. Despite this, within twenty four hours he'd met the fate of all raid bosses. However it is worth noting that players initially face Yogg-Saron with the help of four previously corrupted guardians that must be slain. The battle without their aid is considered to be one of the hardest in game and was even outright dismissed as 'mathematically impossible' on initial inspection.
 * With the final major content release, N'Zoth hasn't appeared in person but it has been revealed that.
 * Cataclysm also features Iso'rath, a gigantic Old God spawned monstrosity in the Twilight Highlands that consists of a giant pit of a maw in the ground and numerous spiky tentacles. Though it's not actually much of a challenge to kill through a series of quests, it is theoretically a lot nastier than most opponents; being inside it puts you in danger of being digested, and in one of the quests you will actually fail to survive its inner defenses and be plunged into a "nightmare" where you are likewise unable to stop the world from being destroyed by the Big Bad.
 * The Elder God of Legacy of Kain fame claims to be an omnipotent demigod, existing beyond any casual interpretations of time and space as "The Engine Of Life" that turns "The Wheel Of Fate", and physically manifests himself as an enormous mass of eyeballs and tentacles. It is eventually speculated by the protagonists that he is Oh, and he's voiced by the late Tony Jay.
 * The Roguelike Incursion has among its pantheon Kysul, the Watcher Beneath the Waves, an unspeakably ancient and foreign being from a long-dead world, keeper of eldritch mind-shattering secrets, whose mere form is so alien that it can cause insanity in the unprepared. It is also, in a spectacular subversion of the expected attitudes of such a creature, strongly Lawful Good.
 * In most Final Fantasy games, the final boss appears as an Eldritch Abomination at some point.
 * Chaos from the original Final Fantasy is an eldritch demonic being created by an endless time loop.
 * Cloud of Darkness from Final Fantasy III: Exactly What It Says on the Tin.
 * Zeromus in Final Fantasy IV is more or less the Anthropomorphic Personification of hatred, borne from the soul of an evil wizard. And he looks like this.
 * Exdeath in Final Fantasy V. He just plain is the part normally, and really looks it  He was born from an aggregate of evil souls sealed into a sacred tree, and later becomes an embodiment of The Void.
 * Not to mention those nameless... things that lurk below the ocean floor. And I ain't talking about dwarves.
 * Kefka from Final Fantasy VI stands atop a large tower of human flesh and organs whose floors represent the levels in Dante's Divine Comedy.
 * Hell, Intangir. Intangir is an invisible monster found before on a remote island, which absorbs all elements, and is only vulnerable to a single, difficult to use, attack. Sketching it gives you monster-like abilities, but usually deletes your game.
 * Jenova from Final Fantasy VII, who is basically an Expy of Lavos from the Chrono Trigger example above, and whose descent destroyed the Cetra civilization. By extension, Sephiroth is half-human, half-Eldritch Abomination. And considering Sephiroth's form and power.....
 * WEAPON: Its first appearance is a creepy bigass eye that almost inconspicuously opens and closes behind a crystal rock face. Then it erupts out of the solid ground as a giant monster, and "WHAT THE HELL IS THAT?!" Though its mechanical Godzilla-like appearance lends it some momentary Narm, it manages to be scary yet again when one of them crawls out of the sea and attacks Junon like it was Cthulhu rising from R'lyeh.
 * The WEAPONs are actually Antieldritch Unabominations. In the backstory of the game, these creatures are the all-natural guardians of the Planet / The Lifestream (Your mileage may vary if the Lifestream can count as an eldritch entity). Unfortunately, humanity has proven itself dangerous to the Planet, so they went aggro on human cities.
 * The "Unknowns" fought in the sunken Gelnika would also qualify. They're Starfish Alien Bosses in Mooks Clothing.
 * Final Fantasy IX:
 * Necron fits this to a T, with the effect being accentuated by Nightmare Fuel scenery and music. Fun fact: Necron (like Amarant) was a replacement name chosen because the original would have exceeded their name character limit. Its original name? "The Darkness of Eternity".
 * Also, there's Ozma. Like Necron, it happens to be a Giant Space Flea From Nowhere.
 * For a less boss-ish enemy, the Mistodons. Giant, undead... bug things... with creepy yellow eyes that flash in alternating patterns giving them an unearthly machine-like feel, and
 * Final Fantasy X:
 * Sin is a giant monster the size of an entire city that emerges from the depths of the ocean to completely annihilate all settlements larger than small villages at random intervals and terrorizes Spira for a thousand years. Even if it is defeated by a High Summoner, it returns a few years later to continue its rampage. Sin leaves swarms of smaller monsters in its path and everyone who survives coming into contact with its toxins (fortunately) suffers from massive memory loss. And apparently it can wipe out entire armies by causing distortions of space.
 * Final Fantasy XI brings back Atomos, everyone's favorite inter-dimensional nightmare from V and IX. This time,
 * The world of Ivalice in Final Fantasy XII is so heavily populated with Eldritches, it's a wonder anyone is still scared at this point. All of the summons are varying degrees of this, plus there's the final boss of the sequel DS game, the Occuria...
 * The Esper Famfrit was apparently a cloudlike being before the gods shoved him into a suit of armor with spikes inside.
 * The Fal'Cie from Final Fantasy XIII are also this, looking for the most part like bizarre machine-things.
 * In Final Fantasy Tactics, practically every major enemy in the game transforms into one of these at some point in the game. One of these Eldritch Abominations,, even fills in the game's role of That One Boss. And the final boss is one from an innocent little girl.
 * Xagor of SaGa 3.
 * The Elder Scrolls has several, the most noticeable being House Dagoth in Morrowind, but for the true position, Sithis takes the cake. Later games attempted to pass him off as a more traditional god of death, but the game's backstory reveals that he is actually a great void, the undying soul of a dead primordial force. The best way to describe him is a concept that is incredibly hard to wrap one's mind around: Sithis Is Not.
 * The Daedric Princes appear to be at least heavily influenced by this concept. They are extradimensional beings said to be born from the blood of the setting's dead creators Anu and Padomay, and are alien beyond human understanding in both morality and form, though they often take a humanoid, if not outright human form to deal with mortals. How they feel about the mortal races varies from prince to prince; many enjoy being worshiped, some just enjoy toying with mortals' lives for their own amusement. Particularly malicious ones have sought to subjugate the plane of Mundus itself and absorb it into their own hellish planes of reality. But all of them have demonstrated a willingness to reward mortals they find particularly helpful, loyal, or amusing.
 * Hermaeus Mora is freaky even by Daedra standards and never bothers with a palatable humanoid form. Often appearing as a vast expanse of eyeballs and tentacles, and on one occasion a swirling vortex of chaos and darkness, he's a seeker of forbidden knowledge who offers forbidden knowledge of his own to any mortals willing to serve him, which risks breaking the minds of those who delve too deeply into it. According to Mora, he himself is forbidden knowledge incarnate, specifically the living incarnation of rejected concepts and ideas from the creation of reality. Or in other words, a sentient rough draft of existence itself!
 * Namira's sphere of influence covers many things mortalkind finds revolting on a deep instinctual level. Cannibalism? Vermin? Decay? The diseased and disfigured? She's essentially the god of all those thanks to her ultimate role being that of the Prince of the Ancient Darkness, the primal fears of mortals given shape. She's also got ties to the aforementioned Sithis, and is said in some obscure texts to be a piece of the Void that broke off and gained sentience.
 * While entirely benevolent as opposed to the far more unpredictable Daedra, the Aedra worshipped by the denizens of Tamriel (save for Talos/Tiber Septim) are just as alien and unknowable as their cousins, if not moreso. Like the Daedra they are said to have been born from the spilled blood of Anu and Padomay, but unlike them they sacrificed their power and possibly even their lives to create Mundus, meaning that they cannot directly interact with it and can only subtly influence it. The latter theory adds to their eldritch nature because it postulates that they're still able to function due to "dreaming they are alive", somehow subconsciously ignoring their own deaths to do so. And the weirdness doesn't stop there: while the Daedra have personalities and roles that are easy to pin down, the Aedra are much harder to comprehend thanks to embodying so many natural laws of Mundus at once that they manifest as aspects with their own personalities, leading to wildly different interpretations of the same deity across various religions. Official lore also states that the planets occupying the infinite void of space outside of Nirn are the bodies of the Aedra themselves, filtered through mortal eyes that can't comprehend what they're looking at.
 * Don't be fooled by their mundane appearances, because Hist Trees aren't ordinary trees. They're a hivemind of impossibly ancient and sentient trees that are quite possibly the sole survivors of the twelve worlds that existed before the creation of Nirn, and are the ruling body of the Argonians of Black Marsh. They created the Argonians in the first place by influencing primitive lizards into drinking their sap, which has other strange properties such as altering any lifeforms that drink it, driving the drinkers insane, and allowing them to communicate with the Hist themselves. They also possess unfathomably deep knowledge from all points in time, ranging from the dawn of creation to a limited understanding of events that have yet to transpire.
 * They don't look too different in comparison to your stereotypical Western dragons, but this series' dragons aren't fire-breathing lizards so much as they are divine beings 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 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".
 * Several Eldritch Abominations called the Deep Ones live in the caverns under the Imperial town of Hackdirt, and have most of its populace under their thrall. They seem to require or enjoy ritualistic sacrifice and have their followers kidnap innocent people as part of their religious rites, with said followers having seriously off-looking faces and being incapable of showing emotions beyond primal bloodlust. Some context clues hint that they're connected to the Daedra in some way, but others hint at a connection to the grotesque Sload race. Yet they could easily be some horrible unknown threat unlike anything seen on Nirn: we never encounter them, and only have their distant, ominous roars from deep in the unexplorable reaches of the Hackdirt Caverns to go off of.
 * Pokémon:
 * Missingno. and its glitchy ilk fit this on a gameplay level: they are essentially junk data given form, and many of them warp or alter music, graphics and save data, possess bizarre dimensions ('M is 23 feet tall, and Missingno. itself is more than three thousand pounds), and can induce game crashes. It's a common speculation that In-Universe, they might as well be Primordial Chaos to the player character.
 * The glitch Pokemon whose name is only represented as a female symbol gets special mention. It has an endless cry that actually sounds like a bizarre twisted song, it's base stats are second only to Arceus, it looks like Giygas, and finally, it weighs 3 tons and is 80 feet tall.
 * The Bad Egg, which you can get by cheating. They can turn other Pokemon into Bad Eggs. They're actually usable in battle. And when they hatch... all you see is an egg, and then the game freezes.
 * In terms of canon examples, Giratina is able to counteract Dialga and Palkia, which are deities in their own right. It lives 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.
 * To a lesser extent, Groudon, Kyogre and Rayquaza. Ancient, slumbering entities responsible for the enviroment. They're millions of years old, and when the former two are awoken, they start to cause the end of the world, requiring the third to intervene and set things right. As Expies of the Behemoth, Leviathan and Ziz, who are arguably cosmic horrors on their own, they may very well be Pokemon Great Old Ones to the Creation Trio's Outer Gods.
 * Kingdom of Loathing...att008 Crimbo event resulted in the Crimbomination. Just look at that thing. It's also about as unbeatable as a typical Eldritch Abomination, no punching out Cthulhu here. To hammer in the Lovecraftian overtones, it's made clear that the guard that was assigned to the factory has been driven completely insane just from looking at it.
 * This is also a rare case where the Eldritch Abomination was created by human hands penguin flippers. The Crimbo factory was taken over forcefully by the Penguin Mafia, and the Crimbo Elves were forced to work in a factory powered by grimicite, which is highly radioactive and caused the elves to mutate. After curing a lot of elves of their mutation, the remaining mutated elves fused together to create the Crimbomination. The Kingdom's adventurers were able to weaken it to the point where the penguins could seal it in a gigantic crate.
 * Unsurprisingly to anyone who knows KoL penguins, they released it next year at the end of Crimbo 2009. The player community brainwashed it into becoming Father Crimbo, and it and its twisted presents will likely be the focus of the 2010 event.
 * There is also the Squamous Gibberer, a fragment of horrible monster from beyond reality who whispers horrible secrets and paranoia-inducing mutterings straight into your mind. Who happens to be a pretty useful familiar.
 * In one fan-made campaign for Free Space 2, Transcend, the Big Bad is a being known only as "the Transcendant", who distorts the laws of reality itself just by being there, and unconsciously evokes human souls to play out particular roles. It turns out that
 * City of Heroes has Rularuu, a Planet Eater who was only defeated by banishment to the Shadow Shard, a weird, twisty dimension. His minions are things like giant eyeballs with teeth and giants made of crystal, he commands reflections of the inhabitants of the worlds he's devoured, and you never face him directly—just fragments of his personality, which in and of themselves are ridiculously powerful archvillains (except for the heroic fragment who helps you).
 * Hamidon, a giant single-cell monster that is the largest Giant Monster in the game and leader of the Devouring Earth faction, may count. Though it is implied that he was once a person that became what he is through a combination of science and magic, there are some people that will swear (rightly so) that he is a god. (He was actually referred to as 'a dark god' in a press release, though the writer later admitted they Did Not Do the Research.)
 * The Devoured, humans contaminated by the Devouring Earth, are smaller, wingless versions of Cthulhu, while Hamidon itself is recognised in the fluff as arguably the greatest threat to all other life on Earth in a world filled with superbeings, gods, demons, and aliens, and is known in-game as the most powerful enemy yet, who you should only try to tackle in 50-character raids.
 * The Praetorian version of Hamidon is even more powerful, having taken over most of the surface of the Earth.
 * The Myrmecols from the UFO series are a pretty-much-textbook example: they're enormous, spacefaring creatures with the power to control the populations of entire planets on a regular basis as part of their reproductive cycle.
 * The Necromorphs and Leviathan of Dead Space.
 * In Dead Space 2,.
 * The Reapers in Mass Effect are . Just one of them is True to the classic Eldritch Abomination style, the Reapers appear to be giant space cephalopods.
 * In Mass Effect 2, . But even dead gods can still dream...
 * In Mass Effect 2, . But even dead gods can still dream...

""""
 * The Reapers often claim that their minds are incomprehensible to organics, and that Reapers think on a level so high that organics cannot even begin to imagine the thoughts a Reaper has. This is apparently not just arrogant boasting: in Mass Effect 3,.

"The strongest, worst thing in the world. A concentrated mass of power, this being hints that the end of the world is near..."
 * There's also the Thorian from the first game.
 * And in Mass Effect 3,
 * In Eversion, a major character is one. In the bad ending, . In the good ending,.
 * The Waterwraith boss from Pikmin 2. Its even mentioned as being anchored in another dimension and being capable of causing fear to the point of insanity.
 * And The Smoky Progg in the first Pikmin, a horrific cloud of evil, that trails black death smoke behind it, and when you kill it, it bursts into flames and sinks into the Earth without a trace.
 * Played for Laughs in Japanese Super Mario World hack VIP MIX 2. The final boss is supposedly the creator of the game himself, who appears as a cluster of 2ch memes.
 * In this flash game, you get to play as one.
 * In this one too, though unusually,.
 * Custom Robo on the Gamecube has Rahu, the Big Bad. Originally an intangible force of destruction that annihilated anything it came across, and very nearly caused The End of the World as We Know It, it for some reason merged itself with a children's toy (the eponymous Robo). That turned out to be a very stupid move: while Rahu is still pretty powerful, it is also defeatable in that form.
 * The Dark One from Quest for Glory 4 is one of these, and an obvious Cthulhu reference.
 * The eponymous town of Silent Hill may be considered one, while the God its cult is trying to raise definitely qualifies.
 * Though, according to the Book of Lost Memories, there is a good chance that said god is also just a monster manifested by the town itself according to whomever has unwittingly influenced the environment.
 * Several entities in Super Robot Wars fit this category. Such as Einst, the inter-dimensional race that claims to have watched humanity from the beginning. Now they wish to "reset" humanity by choosing a new Adam and Eve. They also appear in Endless Frontier, and claim to be the ones who created the titular world, by creating the Crossgate dimensional portal and turning the world into several mini-dimensions separated by a dimensional wall. It turn out that Einst's goal is to return to the original world, "the world of silence". One thing that makes them very strange is they appear to be made of some kind of material that's both organic and metallic.
 * Super Robot Wars D has Perfectio, king of the Ruina Energy Beings from another dimension. Since Perfectio feeds on despair, the Ruina try to turn Earth into his cattle farm by sealing Earth in another dimension. While it's possible to destroy the Ruina, Perfectio is immortal and can only be stopped by sealing the gate to its home dimension.
 * Super Robot Wars K has Lu Kobol, an evil being defeated by Crusians long ago. The Crusians even hid Lu Kobol's fragments in planets across the galaxy to ensure it won't return easily. Yet Lu Kobol resurrects as Energy Beings and seeks to reform itself by destroying every planet that hides its fragments.
 * Super Robot Wars Z mentions Taichi as the entity that controls the fate of all universes by manipulating the Origin Law. It is also the one that created twelve Spheres that grant their holder immense power and limited access to the Origin Law. However, the holder will slowly lose his or her humanity in exchange for said power.
 * Small note is that Taichi is from Taoism with some Mind Screw-level properties. See here for full details.
 * In the 3rd season of the Episodic Telltale Sam and Max games Yog-Sototh, who looks supciously like Cthulhu and has many of the attributes of a cosmic horror, makes several appearences throughout the season. In episode 304,.
 * Darth Nihilus in Knights of the Old Republic II Was Once a Man, but through sheer hatred and hunger became effectively a vampire feeding off of Force energy, wiping out (nearly) all life on at least one planet by his sheer presence, and it is implied that he would eventually grow in power to the point where could kill everything.
 * The Jedi Council consider The Exile to be one of these. The real reason she was exiled in the first place was because they were terrified of her nature as a .
 * The Mask of the Betrayer expansion pack for Neverwinter Nights 2 lets you create one by stuffing a legion of evil and insane murdered souls into the withered husk of a dead bear god. And then the absolute "Evil-With-A-Capital-E" ending has you become a soul-devouring abomination capable of unmaking gods.
 * In Jade Empire, following the destruction of Dirge and, the agonized spirits of those who died in battle were trapped in an unending war between worlds. The resulting spiritual wound in the world was so great that the Nameless Evil, a purely malevolent force that feeds on the mental anguish of the dead, growing ever stronger, was able to find its way into the world. The Water Dragon and other gods had no power over it, because it came from outside of the world and it had no place within the world, no role in the grand order that governs mortals and gods alike.
 * There is mention of Death's Hand outgrowing his form and becoming a monstrosity in the Closed Fist epilogue.
 * In Xenogears, a being named Deus strongly exemplifies this, even looking irreconcilably bizarre to boot. (Incidentally, Deus is located aboard an interstellar spaceship named Eldridge.)
 * By comparison, in Xenosaga it is believed that God Is Evil and one of these...
 * Ragu O Ragula, a monster of practically unimaginable destructive power, appears in pretty much every Wild ARMs game. Almost always a Super Boss sealed safely out of human reach (and out of its reach of humanity). Unseal it at your own terror. Well, might be scarier if it weren't a constantly recurring theme in the series.
 * In Wild ARMs 2, Ragu O Ragula can be defeated using only Brad. What does that make the titular Hero of Slayheim?
 * In Wild ARMs 2,
 * The Heartless of the Kingdom Hearts series qualify while still being cute as a button. Their ultimate goal is to devour the hearts of people and entire worlds and turn them into beings like themselves, and they can never be truly defeated because they come from the darkness in people's hearts. In a minor subversion, it's quite possible that the Heartless were only a minor threat until Ansem's research turned them into a veritable army of darkness.
 * It's later revealed that pureblood Heartless were always around and can exist in harmony with the world. It wasn't until emblem heartless were thrown into the mix as a result of Ansem's experiments that they became a world eating heart stealing menace, and as a result Nobodies came into being as well.
 * Their counterparts the Nobodies fit just as well, being the remnants of a powerful being absorbed by the Heartless, they are beings that stand at the exact edge of existence itself. They are essentially human-shaped voids, but unlike their dark cousins, retain their human memories and intellect to properly use their new power.
 * Unversed are created from the dark emotions in people as a result of the laws of the world becoming unbalanced by the creation of a being of pure darkness, Vanitas. Just Vanitas being near someone with negative thoughts will spawn an Unversed creature and he can also generate them on his own. They are "Unversed" because they are unversed in the complete ways of the world being composed only of dark emotions such as anger or jealousy.
 * is halfway between this and Humanoid Abomination. And also one of the few generally nice examples.  While generally humanoid their appearance changes based on the memories of the observer. Having been described as male, female, and puppet-like by different individuals.
 * From the .hack// series: Cubia. Okay, sure, it's a computer program, but within the realm of The World, it very much qualifies. For one thing, it's a mass of purple tree-root-looking things with a very creepy skull for a head that can materialize anywhere it chooses, and it's even referred to as "The Anti-Existence" once or twice. All of the other AI's running about seem to have some purpose that they're trying to accomplish, but Cubia pops up out of nowhere, and even with a somewhat vague explanation of what it is, no one in the series seems to be able to explain what its goal or purpose is, nor how it was created. Oh, and it's unkillable, save for one very specific method, one the heroes are understandably reluctant to use.
 * Throughout the series it's specifically said (usually by Helba) that Cubia is
 * The unfortunate researchers of the Black Mesa Research Facility from the Half-Life series by Valve discovered a border world, Xen, which all teleportation must be routed through. This border world is ruled by Nihilanth, a monstrous being that looks like a warped, legless fetus, which Gordon Freeman has to take on and destroy. By default it is invincible: any damage dealt to it is instantly regenerated unless the crystals supplying said power is destroyed first. Once that's done, enough injury will open the creature's skull like a flower, revealing a huge portal inside.
 * Opposing Force has the Gene Worm, a big-ass tentacle monster that can spit acid and the flailing tentacles demolish much of the environment as the fight goes on. Similarly to the Nihilanth, its belly contains a portal whose destruction will kill the creature but in order to get to it, you first have to blind the sucker to distract it.
 * The Flood of Halo, a Hive Minded parasitic entity of such ancient, alien power that even the near god-like Forerunners were ultimately forced to sterilize an entire galaxy to put them down... and even then, they eventually rose up again, with the Gravemind calmly pointing out the second time it is being destroyed that this victory will simply delay the inevitable.
 * Heck, the Gravemind on its own; a vast, immortal, reincarnating intelligence. Its physical form is a vast Flood hive full of tentacles and Flood combat forms. And even if this body is destroyed it can rebuild itself if but one Flood Spore survives, it doesn't even have to be from that hive specifically. Any Flood under its control will do. And if that nigh invincibility isn't enough the Gravemind also has telepathic abilities which it can project across interstellar distances. Factor in its love of trochaic heptameter and morbid metaphors and you have one creepy abomination.
 * The Prisoner from the Cryptum novel. Described as a
 * Dark Gaia, a Sealed Evil in a Can Eggman released in Sonic Unleashed, is a sentient force of nature who helped create the universe (by destroying the old one, but meh).
 * There's also a case for the Black Arms; Starfish Aliens with a fairly horrific reproductive cycle, a deadly toxin that can wipe out an entire planet and an innate talent for Chaos Control apparently hard coded into their DNA. And then, of course, Black Doom's ability to turn one of his eyes into a literal Starfish Alien.
 * Chaos, from the Sonic Adventure.
 * There's also from |Sonic the Hedgehog 2006: Iblis, a massive beast of destruction made only out of fire; Mephiles, a gasseous-liquid mind of complete corruption and shadowy powers;.
 * In Sonic Generations, there's the Time Eater. While most of its presence in the game is, Eggman reveals its natural purpose, when he discovered it, Between that, its looks, and the dimension the game takes place in, as well as the location of the last boss fight...
 * Sanity: Aiken's Artifact has individuals given psychic abilities. The psychic abilities, however, cause individuals to become insane if they are overused, and these abilities
 * In Mana Khemia: Alchemists of Al-Revis, comes close. It was given a Bonus Boss Palette Swap, called "Pain", described this way:


 * The Soulless Ones of Lusternia. Prototypes of the eventual template used to create the Elder Gods, they were born without souls and exist solely to devour - Gods, infant Gods, mortals, nature spirits, animals, even each other. They imbibe the power of those they devour, making them stronger with every meal. By the present day only five remain, but those five have devoured so much of reality that they can no longer be destroyed, unless you want to take down the universe with them, so they're sealed away. For the time being...
 * Baal in Disgaea is just as old as the universe, absurdly powerful, and immortal.
 * It's implied that the most ridiculously powerful of Disgaea demons start to turn into these. was becoming a completely inhuman (so to speak) Omnicidal Maniac, and had to turn to Reincarnation for a way out.
 * This is a surprise in Disgaea 3 when you realize that Mao
 * Disgaea 4 has you say hello to Death/Extermination Submersible Combat Organism—aka [[media:Desco 6996.jpg|Desco]], the cutest widdle eldritch abomination that ever wanted to be the Final Boss. Of course, just because she's Moe doesn't mean she's incapable of turning you into a gibbering mass of fear and insanity if [[media:yogsothoth 3263.jpg|her attacks]] are anything to go by.
 * Prototype has the Blacklight Virus. A sentient virus that consumes biomass, can shapeshift, absorbs peoples' memories, singlehandedly demolishes entire armies, and is Nigh Invulnerable . Even other viral monsters end up on its menu.
 * There is also, a Humanoid Abomination who looks like a normal, good-looking woman, but is basically.
 * And there's also
 * In Prototype 2, the Blacklight Virus now has a new host: James Heller. And his powers are far more monstrous than Alex Mercer's in the first Prototype, thanks to his "tendrils" power. Whenever tendrils are involved, the result is masses of flesh dangling from the buildings with strung-up corpses caught like flies on spider silk.
 * Yume Nikki takes place entirely in a girl's demented nightmares, and it shows. Between the infamous Uboa, the screamer-like event generally known as "FACE", almost every inhabitant of the White Desert, the strange Mayincatec figures floating around beneath the floor, and the assorted other bizarre monsters inhabiting corners of her head, Madotsuki could give more than a few Cosmic Horror Story writers lessons. Whether any of them are real outside her head is a matter for Wild Mass Guessing, however.
 * The Castlevania itself, described by Alucard in Symphony as a "Creature of Chaos," explaining why the castle never looks the same. In Aria of Sorrow, it turns out that the castle spawned from the Chaotic Realm in response to the Dark Lord.
 * This series' depiction of Dracula is actually closer to this, with a dash of The Antichrist, than to a traditional vampire.
 * Legion/Granfalloon, a terrifying floating ball of screaming corpses with some sort of tentacled thing in the middle. Oh, and in some games, the corpses reanimate and attack you.
 * Fable's Jack of Blades may well count, given their origins lie in a realm referred to as The Void and his form seems entirely dependent on.
 * The entire setting of Prey, albeit being techno-organic alien in nature. Big enough to host every level save for the introduction and ending, and never seen in its entirety. Reality-violatingly ugly as in portals, spatial anomalies and multi-directional gravity. Happens upon the Earth on one night without any warning. The hero even meets survivors who demonstrate knowledge to survive and assist him.
 * It is implied that it seeded Earth with life just so it could come back and eat everyone.
 * Even worse. They can, apparently, invade the spirit realm via portals. Although, even they are taken aback by the sudden spirit activity.
 * Metroid Prime has the sentient planet Phaaze. Among other things, it is inadvertently responsible for introducing the Starfish Alien like Ing to normal space.
 * Phantoon. It's a ghostly... thing that inhabits abandoned ships. Its primary projectiles are eyeballs made of blue fire, it can turn invisible and intangible, it can open dark rifts and summon flying disembodied hands with eyes in their palms. It itself resembles a sea creature of some sort (with Combat Tentacles, naturally) with a gaping toothy maw... which houses an eye. And no apparent throat. This creature just makes no sense.
 * Metroid: Other M concept art shows that Phantoon has a humanoid-shaped body to go along with that tentacled head and disembodied hands. The reason the head and hands are disembodied, though, is because he pulls the common Eldritch Abomination trick of having most of his body existing in dimensions the human senses aren't built to handle.
 * Additionally, Mother Brain. She's a sentient, cyclopic spiked brain
 * Samus herself could be considered to be almost an Eldritch Abomination from the Space Pirates' perspective. Entire armies of their forces have been slain by her, she regularly shows up and wrecks their plans (usually just because they happen to be on the same planet as her actual objectives), and many of their bases, not to mention the planets said bases are on, are most likely going to explode in the near future; they've even dubbed her "The Hunter". In Echoes,
 * Mario & Luigi: Bowser's Inside Story: The Dark Star's introduction sounds straight out of Lovecraft, and by the time it's inevitably unleashed, it's a sinister blob of darkness that has the Mario Bros choking from simply standing near it. On the other hand, it's up against Bowser, who looks forward to the challenge.
 * And a few years earlier and on a different system we had, whose very presence is capable of plunging the world into an unholy darkness. Bonus points for being insanely difficult to defeat and rather unsettling.
 * Gobtron.
 * In Ratchet and Clank Future A Crack In Time, you actually get a gun that opens a portal to a cosmic horror that will eat your enemies. Its name is Fred.
 * BlazBlue has The Black Beast, a horrifically powerful monster that appeared about a hundred years before the game's story kicks off, nearly destroyed the world, . There's also Arakune, a crazy blob...thing  . And of course   whose true form resembles.
 * The Bydo in R-Type. As the instruction manual puts it, "A living weapon built with the self-replicating properties of DNA, the Bydo has physical mass, yet exhibits the properties of a wave. It diffuses easily and fills any environment it encounters. The Bydo can even interfere with, and ultimately consume, human thought itself."
 * At least one earlier R-Type had some rather terrifying mentions of what was being done to pilots to avoid risk of infection. They can easily be dismissed out of canon, presented as rumors of what the government may or may not be doing.
 * About the only effective weapon against the Bydo is themselves. Humanity is only standing its ground by using carefully controled Bydo flesh in the form of the Force units. Whether they can ever have a true victory over an enemy that exists outside time is another matter.
 * They can also infect and corrupt both living things and machinery. How? A Wizard Did It—no, really. They're canonically stated to have been created using both science and black magic.
 * The Serpent Riders from the Heretic and Hexen games are immensely powerful alien demons from beyond the crystal wall at the edge of normal space that slipped in when it was damaged. Only one of them really has the Cosmic Horror look, though - Korax from Hexen, who is a bizarre humanoid-reptile-Xenomorph thing. "Surely even hell would never spawn such a being." (D'Sparil looks like a cowled wizard, admittedly riding a humanoid serpent, and Eidolon like a more regular demon.)
 * The Maw has the player character guide the title character, an Extreme Omnivore that grows in size as it's fed. It can also take the physical properties of what it eats (eating a salamander-like creature makes it a lava beast and eating an electrified creature makes it firefly-like). Think of an Ugly Cute Kirby as your pet.
 * Quake's Final Boss is ... not that it lives up to the name though.
 * The Virus in Homeworld: Cataclysm is one of these. The local Precursors apparently picked it up in subspace and disabled their ship in an attempt to contain it. They failed, obviously.
 * In the first Homeworld, there is a small Breather Level called "The Sea of Lost Souls". It takes place, fittingly, inside a proto-star nursery (giving the level a very ethereal skybox), and in it is a ship known only as the "Ghost Ship", which projects an energy field that instantly subverts your capital ships and causes them to attack anybody that comes in range. When you finally disable the field and retrieve data from it, you learn that it is millions of years old (possibly older than the proto-stars around it) before the Bentusi (powerful, ancient alien benefactors) arrive and request the information for themselves... because this ship terrifies them. You never learn anything else about the ship, in any of the games.
 * In The Lord of the Rings Online, players get to explore unpleasantly organic looking caverns around the nameless lake deep beneath the bridge of Khazad-Dum, caverns which are home to a mind-controlling fungus. It grows on the orcs and trolls, reducing them to pulsing masses of green fungus erupting from their skin, almost like exposed brains. Don't ask what the giant spiders look like under its taint; just don't.
 * Now consider, these abominations can be found within sight of the base of the endless stair, the deepest point reached by dwarfs, but the tunnels beneath Moria go far deeper than that. What else might be down there?
 * Now consider, these abominations can be found within sight of the base of the endless stair, the deepest point reached by dwarfs, but the tunnels beneath Moria go far deeper than that. What else might be down there?


 * Also, the Nameless as mentioned under 'literature' pull some appearances when you're at very high level. They include headless creatures with fanged mouths between their shoulders, massive hulking beasts resembling lobsters gone wrong, and the Watcher in the Water. Their leader is a massive sluglike monstrosity called the Mistress of Pestilence, which has an exposed brain and multiple eyes and is also the source of the previously-mentioned fungus.
 * The Nightmare Ned video game features several shadow creatures that are responsible for Ned's nightmares.
 * Alan Wake
 * Even worse: it has a human Avatar controlled by the  which is implied to be the avatar of an even worse thing.
 * The third Jak and Daxter game has the corrupted version of the Precursors, known as Dark Makers. Basically, they're Precursors that were overexposed to Dark Eco. Given the different types of Dark Makers, their resemblance to the Precursor Oracles, and, there is plenty of evidence for the popular fan theory that they're really just robots. Until official confirmation, however, they're this.
 * No love for the Metal Head Leader from Jak II?
 * In La-Mulana, one of the bosses is a giant eye monster with tentacles and a massive eye, which is reminiscent of a eldrich abomination. However, the real award goes to
 * Sin and Punishment: The inhabitants of Outer Space (which is apparently a separate dimension/realm/something from the space we know, which is called Inner Space) are described like this. They are not alive in any sense known to Inner Spacers, and can shapeshift to mimic anything... including entire planets. They are defeatable, but it is really not easy to do (and the only inhabitant of Outer Space we see seemingly effortlessly survives the heroes' efforts to eradicate it, though they are unaware of this). Even some of the Inner Space characters get distinctly Lovecraftian at times; see Armon Ritter of Sin and Punishment 2, particularly his final form.
 * In Bayonetta, these are usually summoned by Bayonetta to finish off bosses or Giant Mooks. These range from multieyed crows to giant worms that sound like elephants. In fact, the final boss has Bayonetta
 * The angels themselves count, specially Iustitia, one of the cardinal virtues, intentionally designed like a mixture of a carnivorous plant with a tentacle monster with creepy cherubic baby faces everywhere because of its moral ambivalence.
 * In Devil May Cry, the boss Nightmare definitely qualifies as this. Its natural form is a pile of hideous steaming goo, filled with the remains of those it has killed. It is completely invincible in this form, and constantly attempts to assimilate Dante into itself. If it succeeds, it sends Dante to a cavernous void that the enemy file says is a manifestation of Dante's subconscious fears. When the magic seals in the room are broken, it changes from its goo form to a form that can be damaged... and is also much more dangerous. This form looks like something straight out of an HR Giger painting. It shoots homing projectiles that are best described as demonic leeches, constantly drains your magic, and only has one weak point. However, get too close to it, and it shoots out huge spearlike appendages created from its inner core at blinding speed. The enemy file on it says it's not sure whether or not the thing is even alive or whether it's some form of horrifying machine.
 * In Devil May Cry 3, the second to last boss in the game also has traces of this. It is a amorphous blob with an ever changing amount of tentacle like limbs, and can summon out of itself an army of fishlike monsters that constantly close in on you. Looking at it, it is difficult to tell if it is supposed to have a face, or even a head, or perhaps several dozen.
 * In number two, Argosax the Chaos is this. It's a repulsive hivelike creature made from a mishmash of almost a dozen already horrific monsters, half of which are eldritch abominations themselves!
 * The Zerg Overmind from StarCraft might arguably be classed as something like this. While it's made from normal cellular matter, its "form" is nothing more than a vessel for the collective intellect of trillions of Zerg, with enough psychic power to rip open space-time with ease and bend anyone to its will. It doesn't help that it's a hideously large brain-like... thing with a great big eye reminding people of Sauron. Or that its purpose is to assimilate or exterminate everything, everywhere.
 * Starcraft II
 * Said thing, going by the names of "The Fallen One", "The Lord of The In-Between-Places" or "The Living Heart of the Void" (identified by the humans as "The KL-2 Entity")
 * Word of God at BlizzCon 2010 said that "The Fallen One"/"The Dark Voice" Big Bad who altered the Overmind is NOT "The Voice in the Darkness" (and all those other names) that was freed by the humans. They are separate Eldritch Abominations. Also, it was said that the Zerg, in spite of their Woobie'd leader are going to remain Exclusively Evil (along with Kerrigan, but that remains to be seen exactly) even though they are needed to defeat the Fallen One and his protoss-zerg Hybrids.
 * Aquaria features the Creator, who starts out safely beyond the Bishounen Line but gets more and more monstrous as the battle progresses. Some of his earlier creations also qualify on looks alone, if not on powers.
 * In Epic Mickey, The Phantom Blot has been changed to be one of these. He was unwittingly created by Mickey and left to corrupt the world of forgotten toons for decades.
 * The robotic Beetleworx, which The Mad Doctor has built, were originally created to reconstruct the Wasteland. Eventually, they were altered to try to destroy the titular character. The concept art is pretty worse compared to final product, considering the normally child-friendly-associated Tigger was found on one. With Fangs!!
 * EVERY SINGLE True Final Boss in the Etrian Odyssey series. The one in the third game takes the cake. Just try to count all those eyes and tentacles...
 * In Amnesia the Dark Descent you are being followed by these "things" or "shadows" as you explore the castle. You have no weapons/defense other than hiding either, so there is a sense of hopelessness. While their appearance is a blurry/melted shambling humanoid, staring at them for more than a few seconds will cause you to lose sanity (an in game statistic).
 * While the Parasite Eve series can be considered to have skirted the trope at times, it seems that the upcoming sequel, The 3rd Birthday, has dived head-on with its new menace, known simply as the Twisted. Colossal tentacled monstrosities, the first thing we learn about them in the trailer is that they somehow erode time and space, and it seems the only way to stop them is by using Time Travel Body Surf to Set Right What Once Went Wrong.
 * Galvaran, Jabir, Napishtim, etc. in the Ys series. Many of these were created when the humans who stole the Black Key attempted to recreate White and Black Emelas.
 * Resident Evil Outbreak had this in the form of Nyx, a giant mass of seemingly acidic goo that had the corpses of the troops it digested, as well as the corpse of a digested Tyrant unit hanging out of it. Speculation claims it's some sort of plant matter, fungus, or a piece of T-Virus somehow magnified, but it's still horrific, especially it's implied ass cheeks...
 * The final mutations of most of the Big Bads, especially G, Nemesis, Alexia, and Saddler.
 * The Las Plagas itself may be this, it was found a hundred years prior to the story, centuries before Umbrella employed its scientific techniques to produce it's famous viruses.
 * The Chaos beings in Ancient Domains of Mystery. Most of the monster descriptions for them are Description Porn about how Mind Screwy they are.
 * Leave it to the designers of LittleBigPlanet 2 to make an Eldritch Abomination out of a vaccum cleaner! The Negativitron travels the cosmos, constantly sucking up all material in Craftworld. It can also be considered, too.
 * While the six dragons in Rift are explicitly stated to be mere manifestations of the Elemental Lords, Akylios takes the cake; his description mentions he was mad BEFORE he started gathering all knowledge, and that he doesn't actually care what all the other dragons do...
 * The abominations in the circle tower and the within Dragon Age.
 * The Big Bad of SaGa 3 is Many of the other enemies could count as well, some being direct Shout Outs to the Cthulhu Mythos.
 * In Return to Krondor, the Dark God seems to be this. An entity that is very dangerous and had to be sealed away. A group of depraved individuals worship this god, and want to release it into the land of Midkemia. Releasing it would be a Very Bad Thing To Do.
 * There is the Red Queen of American McGee's Alice, especially in her true form.
 * The sequel, Alice: Madness Returns has ruin enemies, which are basically black Blob Monsters with Doll parts.
 * The Old One from Demon's Souls.
 * The Destroyer from The Legend of Spyro: Dawn Of The Dragon counts. It's an ancient mythological monster whose existed since the beginning of time. It exists for only one reason, to cause the end of the world in a wave of fire and ash when unleashed. Oh, and it's as big as a mountain and made of rock and lava. The only way to actually stop it is
 * Subverted with the "Dark God" Doma, The final boss of Fire Emblem Gaiden. He clearly appears as one, but his intentions are more Darwinist than most other comic horror entries.
 * Also, there's Abaddon, the God of Secrets from Guild Wars.
 * Borderlands has Okay well, it was supposed to be something like this, but it basically became a Narm-riddled festival of "Shoot the tentacle-thing's giant wobbly arm-testicles". No, really.
 * Septerra Core. Ouroboros is a giant monster that dwells somewhere near the Core of the world and is said to be as old as Septerra itself. It can be summoned with Fate Cards to inflict massive fire damage to the target and the only part of it seen are it's three heads, that alone are comparable in size with other, rather huge, summons. And it isn't known how large the rest of it's body is. It's also rumored that it's an inteligent being and that if it's heads will ever all agree on something, it will cause The End of the World as We Know It.
 * In the FEAR games, Alma gradually becomes one of these as the series progresses. She starts out as simply a whispered presence flitting about at the edge of the Point Man's vision, occasionally emerging to inflict horrific violence on bystanders, up until . At that point her power is fully unleashed, and she heads into full-on Lovecraftian horror that ressurects bodies, brings spirits of massacred civilians back as violent wraiths, and is surrounded by miasmic otherworldly tentacles and appendages whenever she manifests her physical body. By the third game, Alma's presence is ripping reality apart, causing manifestations of demonic beasts and hostile physical spirits, as well as driving the civilian population of the city to madness, turning them into savage cultists that worship her.
 * Spectrobes practically runs on this trope, the main villians are the Krawl, which are amoeba-like monsters that are bent on destroying planets, the smaller ones are simply living blobs, while the larger ones are more eldritch the bigger and more powerful they are.
 * The High Krawl, ESPECIALLY Jado, whom refers to himself as being "The Great Negative", Krux, the Big Bad of the series, however, is a Humanoid Abomination.
 * Not only is Shikkoku no Sharnoth full of these in the form of the <>, but.
 * Terraria has the Wall of Flesh: An enormous wall of flesh with eyes and mouths that can only be encountered by throwing a voodoo doll of your guide into the lava pits of the underworld, which will chase you through hell until either you or it dies. It will spit giant leeches out of its main mouth which will chase you down, try to eat you with its many mouths, and shoot you with eye beams. Oh, and you can't escape without killing it.
 * One of the chief reasons Fatal Frame is so scary is that it avoids this trope: all the ghosts are humanoid and that much more frightening for it. Except one: Utsuro from the Xbox version of Fatal Frame 2. It's fought at the end of Survival Mode, in the Hellish Abyss. It emerges from the * itself, and resembles a giant... mass of... stuff with short stumpy arms and a vague face. It's described as a manifestation of all the pain and despair of the people who have died there, and it constantly makes noises that sound creepily like a bunch of people sobbing in terror. Fortunately, the Camera Obscura still works on it.
 * The various Domz aliens from Beyond Good and Evil. Especially the Domz Priest, who looks very squid-like.
 * Insanely Twisted Shadow Planet was created by small Eldritch Abomination, that assimilated the Sun and turned it into bio-mechanical-shadowlike mnostroity..
 * Many of Cthulhu Mythos deity appear in Demonbane. Although the Great Old Ones are treated as just powerful monsters, the Outer Gods still play it straight. Unlike in mythos, most Outer Gods are sealed in compact universe inside the Shining Trapezohedron. But Azathoth still generate countless universes from inside, make it the center of multiverse (and destruction of Shining Trapezohedron will doom everything, for Azathoth will turn whole multiuniverse into Eldritch Location once it's free). At least two Outer Gods are free, for neither of them can be sealed. One being Yog-Sothoth (being embodiment of all time and space) and other is Nyarlathotep (being will of Outer Gods, and since the multiverses come from thought of Azathoth, ). One of its form, Clockwork Phantom, is eleborate version of Tik-Tok Man in mythos, being mechanic abomination that assimilated whole universe into itself.
 * Many of the major bosses (especially later in game) from the Super Famicom Enix RPG Mystic Ark definitely follow this trope with its disturbing boss designs (which are all animated). Even more-so for the final boss
 * The Bed of Chaos in Dark Souls is an unholy fusion of the Witch of Izalith and the Flame of Chaos after the Witch attempted to recreate the First Flame. It's a massive treelike monster that sprouts a being of pure fire after its defenses are broken.
 * Soul Edge started out as an ordinary sword, but became the avatar of Inferno, a soul-eating abomination that takes over its wielder. While it still resembles a sword that changes form depending on its wielder, it transforms anyone infected by its curse into Malfested, monsters bound to its will. When damaged, it retreats into Astral Chaos and either repairs itself or scatters its shards around the world. And  isn't as different as many expect...
 * In Massive Multiplayer Crossover Namco X Capcom, the Soul Edge is a missing half of Big Bad 99 and has power to cut anything. Its mere present accidently severs the link between, which mean it can cut soul in halves.
 * This game allows you to play as one, demonstrating either Video Game Cruelty Potential or Video Game Caring Potential... Although,
 * RuneScape has several examples:
 * The Inadequacy and other monsters fought during "Dream Mentor," all of which are embodiments of Cyrisus' negative emotions.
 * That...thing that has become in "A Soul's Bane." Specifically, it looks like
 * The Stalkers, otherwordly multi-eyed beings that can cause headaches with their speech alone. Several of them are bosses, and all of them are grotesque monstrosities. Did we mention their leader has the title "World-Gorger?"
 * Gohma Vlitra and from Asura's Wrath are relatively hard to comprehend especially when the latter   The extra materials even say that their Gender and age is unknown.
 * Kid Icarus: Uprising has monsters such as Ornes and.
 * Golden Freddy from the Five Nights at Freddy's games seems to be one of these. Unlike the other animatronics, he teleports right into your office if you look at a certain poster, and the only way to get rid of him is to pull your camera back up, basically un-summoning him. Looking at him will cause a bunch of hallucinations and will crash your game. In the second game, he's flat-out shown disappearing from view, and kills you by having his head charge at you separate from his body. Whatever he is, he is not normal.
 * Shadow Freddy and Shadow Bonnie from the second game seem to be of a similar vein, as looking at them for too long crashes the game, and in Shadow Bonnie's case, he flat-out disappears from view like Golden Freddy does. While Golden Freddy at least has some sort of explanation behind his existence, there is nothing to give context for these two.
 * The Epic Battle Fantasy series has a twist on eldritch horrors with intentionally glitched creatures with scrambled sprites simply known as "glitches" in the 4th and 5th games. In spite of very weak stats, they can absorb Non-Elemental damage (something normally impossible) of either physical or magic type depending on the glitch and their attack instantly kills a character. The party's encounter with a small group of glitches in the 4th game makes them question the nature of their universe (Lance in particular, being the tech specialist), and an encounter with an even more powerful and self-aware glitch in the 5th game that toys with them, essentially using them as vessels to taunt the player and messing with the game's interface by replacing every icon with random piles of pixels, and keeps coming back shortly after being defeated, leaves them all traumatized for life.
 * Super Smash Bros.: No matter the game, you always tend to face at least one as an end boss.
 * While they're ultimately just floating hands (heavily implied to be the hands of a child playing with his toys, at that), Master Hand and Crazy Hand are presented as this trope. Their status as large, disembodied hands with weirdly deep voices makes them feel wrong when pitted against familiar video game characters, and they have a number of weird and inexplicable powers - lasers shot from their fingers, laying spike traps made of light on the ground, and shooting gigantic bombs and bullets despite having no mechanical components to them whatsoever. Even their more mundane attacks like slaps and pokes deal weird elemental damage and status ailments for some reason. As weird as they are though, from Brawl and beyond, they're often the prelude to even weirder and more powerful abominations.
 * Tabuu from the Subspace Emissary mode of Super Smash Bros. Brawl looks like a bald human man made of neon blue light, with rainbow-colored butterfly wings that can instantly kill anyone that's hit with the "off-waves" they produce. Said to be the embodiment of Subspace itself, he can't leave his realm so he instead pulls bits and pieces of the Smash world into his so he can warp it into an abominable hellscape that's more to his liking.
 * ''Super Smash Bros. for Nintendo 3DS / Wii U has the Master Core, either a superpowered form of Master Hand, or some sort of abomination that took his guise - and neither option is pleasant. A swarming mass of darkness, Master Core takes on a number of terrifying forms, such as a gigantic apelike creature, a hellish scorpion monster, a swarm of vicious living swords - - during its boss fight. Its true form seems to resemble a Smash Ball and is harmless... unless you decide to take your sweet time killing it. Then, it unleashes a flurry of one-hit kill attacks that look uncomfortably similar to Tabuu's off-waves.
 * Galeem from the World of Light mode in Super Smash Bros. Ultimate is a malevolent, living sphere of light wreathed in freaky blade-like angel wings that kicks off the plot by killing everyone in the universe except for Kirby, and proceeds to enslave the spirits and bodies of those he killed as his "puppet fighters" that go on to infest the world he destroyed. Not much, if anything about him is explained, but if there's one thing we do know about him, it's that he's cruel and sadistic to a fault. A trait shared by...
 * Many of the horrors infesting Spooky's Jumpscare Mansion are otherworldly abominations that count as this to some extent.
 * Specimen 7 is a horrific wall of twisted, red-and-black corpses that looks uncomfortably similar to Giygas, and one of the few Specimens capable of instantly killing the player. What this thing is isn't really explained that well, but it seems to be some kind of entity based on Jungian psychology, and is possibly a manifestation of the player's past trauma given shape.
 * 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 ribcage. 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.
 * Specimen 9 is a red, creepily realistic floating skull-like head that manifests if you idle for too long in a room, or get lured into a deathtrap in certain rooms, and will instantly kill you once it touches you. Oddly enough, it has something of a mundane origin, simply being a mass of clay that came to life under unclear circumstances, but something happened to make it completely and utterly wrong. It survived its own death, corrupts its CAT-DOS entry simply from existing, and can warp reality itself in a handful of rooms. It says a lot when Spooky is afraid of this thing..
 * Specimen 12 doesn't look that special, and is seemingly a creepy old man who stalks you around a mansion inside of Spooky's own mansion and instantly kills you if he catches you. But you find out later that.
 * Elder Dragons as a whole tend to skew towards this status in Monster Hunter: 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 some other biological function. Some are worshipped and revered as gods, others feared as demons, and they often have a visible effect on a map they're present on - namely, some kind of environmental anomaly that has caused all monsters native to the area to flee for their lives.
 * The Fatalis is easily one of the most eldritch and unholy monsters in the series, which is no small feat. Flavor text descriptions for the armor and weapons made from their body parts state that they plague those who wield them with horrifying nightmares, dark voices in their heads, and animalistic bloodlust, until their wearers go insane or die under mysterious circumstances. They can also possess their wielders, and possibly turn them into another Fatalis entirely. This, combined with the fact that the Fatalis sword in Pokke village is constantly regenerating scales and implies that it's impossible to truly kill a Fatalis since they'll always find some way to come back, no matter how impossible it should be. Their powers are also anomalous even by the standards of other Elder Dragons, with Crimson Fatalis being able to somehow 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.
 * Yama Tsukami is weird. It looks nothing like a traditional dragon and is 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.
 * In a series where wielding two different elements can make a monster especially dangerous, Alatreon having power over all of them is downright mindbreaking. 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 materials is 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 it passively generates from its body and weaponizes in the form of explosive projectiles and superheated 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.
