[[caption-width-right:318:"[[StrawNihilist Understand, that there is no point in living]]! [[HopeCrusher Cry, that there is no answer]]! [[AsLongAsThereIsEvil Where there is darkness, there are shadows]]! [[TheHeartless I, myself, am all of you humans]]!!"]]

{{Eldritch Abomination}}s in VideoGames.

----
* ''VideoGame/AlanWake'' [[spoiler:implies that the Dark Presence is one of these; trapped under Cauldron Lake and waiting for someone to set it free..]].
* In ''VideoGame/AmnesiaTheDarkDescent'', you are being followed by "things" or "shadows" as you explore the castle. You have no weapons or 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 status). [[spoiler:Worse, those are just {{mooks}}. The journal scraps/notes you find hint that the main bad guy "comes from beyond the void" and "warps reality with its presence", which you experience as you progress through the game and parts of the castle are warped into nightmarish versions, with [[MeatMoss raw flesh coming out of the walls]].]]
* The Chaos beings in ''VideoGame/AncientDomainsOfMystery''. Most of the monster descriptions for them are DescriptionPorn about how {{Mind Screw}}y they are. And then you get to the BigBad, which the game says simply can't be described, ''period''.
* Gohma Vlitra and [[spoiler:Chakravartin]] from ''VideoGame/AsurasWrath'' are relatively hard to comprehend, especially when the latter changes into its final form. The extra materials even say that their gender and age are unknown.
* In ''VideoGame/{{Bayonetta}}'', Jubileus and Queen Sheba are analogous to {{God}} and {{Satan}} respectively, but the severe CrapsackWorld means they don't actually care about individuals and are fairly mindless despite their horrendous power.
** The [[LightIsNotGood Angels of Paradiso]] themselves count, especially 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. Breaking off any angel's golden armor and marble face [[http://vignette1.wikia.nocookie.net/bayonetta/images/a/a8/Decoration.jpg/revision/latest?cb=20140930221025 reveals their true alien countenance.]]
** The Demons of Inferno also count, being just as nightmarish and incomprehensible as you'd expect a demon to be. And no, LightIsNotGood does not automatically translate into DarkIsNotEvil; unlike the angels, the demons don't make any secret of being the eldritch monsters they are.
* The Domz priest in ''VideoGame/BeyondGoodAndEvil'' commands an army of twisted beasts and people corrupted by its influence, able to control all of them with gargantuan psychic powers that render nearly anyone helpless against it. It is only able to be defeated at all because [[spoiler:[[TomatoInTheMirror Jade is also an abomination]].]]
* ''VideoGame/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, [[spoiler:and turns out to be a fusion of Ragna and Nu-13 trapped in a StableTimeLoop]]. There's also Arakune, a crazy blob... ''thing'' [[spoiler:who is actually a failed attempt to create The Black Beast]].
* In ''VideoGame/{{Bloodborne}}'', it is revealed that the plague afflicting the city of Yharnam originates from [[spoiler:a race of monstrous otherworldly beings known as "Great Ones." These creatures have strong [[CosmicHorrorStory Lovecraftian overtones]] in their appearance and underlying themes, and are worshipped by mad cultists in the same manner as Lovecraft's [[CthulhuMythos Great Old Ones]].]] [[spoiler:Despite having similar resemblance to Lovecraftian stories, the Great Ones ''actively'' seek to ascend and guide humanity with their insights rather than ignoring the humans [[HumansAreInsects as if they were insects]]. [[ReligionOfEvil The Healing Church]] and [[MadScientist Byrgenwerth College]], on the other hand, are [[EvilerThanThou far more sinister]] [[HumansAreCthulhu and incomprehensible]] than the Great Ones themselves. Some Great Ones, such as Rom the Vacuous Spider and the Moon Presence, are even implied to have been [[WasOnceAMan once humans]].]]
* ''Franchise/{{Castlevania}}''
** The Castlevania itself, described by Alucard in ''VideoGame/CastlevaniaSymphonyOfTheNight'' as a "Creature of Chaos," explaining why [[ChaosArchitecture the castle never looks the same]]. In ''VideoGame/CastlevaniaAriaOfSorrow'', it turns out that the castle spawned from the Chaotic Realm in response to [[{{Dracula}} the Dark Lord]].
** This series' depiction of Dracula is actually closer to this, with a dash of TheAntichrist, than to a traditional vampire.
** In "Aria of Sorrow," the boss of the Underground Cemetery is this.
* ''VideoGame/ChampionsOnline'' has the Kings Of Edom -- godlike beings from previous universes with names like "The Heart in Man's Dementia" and "The Muse of Lethargy and Despair". They dwell in the Qliphotic, a realm beyond even hell, that has been revealed to be [[spoiler:a dying universe. They dwell within a universe, draining it of all energy and life, then take new avatars in the next universe. And our universe is in their sights as their new home.]]
* Lavos from ''VideoGame/ChronoTrigger'' -- 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. Its mere presence and feeding on the planet weakened the fabric of spacetime at key moments of history (therefore allowing {{time travel}} to be possible, [[HoistByHisOwnPetard which set up the series of events leading to its demise at the hands of the local]] MeddlingKids). Even better, Lavos is summonable through occult ritual and is itself a source of magical power.
** In ''VideoGame/ChronoCross'' it merged with Schala and became the Time Devourer, which lurks at the Darkness Beyond Time where cancelled timelines go, growing in power and preparing to destroy universe. We see it in its full hideous glory in the BonusDungeon of the DS remake, there known as "Dream Devourer". After you "win," TheBattleDidntCount since it just absorbs a self from another reality where it doesn't die.
** There are also InUniverse theories about another Entity acting on the world, though what it is isn't really clear - most likely, it's the will of the Planet itself. The Entity interacts with the world only through the creation of the Gates that allow time travel, which are described as being like the memories of a dying man; the only time that it unambiguously takes action in the game is when it [[spoiler: creates a temporary Gate to allow Lucca to reverse her mother's maiming]].
* The eponymous being from ''VideoGame/ChzoMythos''. 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 ReligionOfEvil on his side, a practically invincible right-hand-man, and [[spoiler:had all but succeeded in creating the bridge between our realm and the Ethereal Realm...]] We'd be all boned had everyone not been [[spoiler:fooled to the point where they hadn't realized that Chzo would actually die if he crossed over to Earth. He wasn't intending to cross over, anyway -- he was actually trying to get a New Prince. [[TheBadGuyWins And he succeeded]]. After all the deaths, trauma, and general misery, nobody was expecting Chzo to actually win in the end.]]
* ''VideoGame/CityOfHeroes''
** Rularuu, a PlanetEater who was only defeated by [[SealedEvilInACan banishment]] to the Shadow Shard, a weird, twisted 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 didn't check the facts.) It's 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 [[MirrorUniverse Praetorian]] version of Hamidon is even more powerful, having taken over most of the surface of the Earth.
* ''VideoGame/CliveBarkersUndying'': The Undying King, plus many of the creatures in Oneiros.
* ''VideoGame/CookieClicker''
** The Grandmapocalypse, for those who [[DugTooDeep get too greedy with their cookie production]].
** Turns out Santa Claus is one, if you upgrade him enough. Although the fact that the newsfeed keeps referring to him as nice implies that he's CreepyGood.
* ''VideoGame/CopyKitty'' has the BonusBoss, [[https://www.youtube.com/watch?v=1qbUygmOO8s Exgal]]. Its name cannot be displayed except as bizarre characters, and its life bar is messed up and never goes down. Instead, Boki has to destroy its three puppets. Each time she does so, she can absorb one of their similarly unnameable but ''extremely'' powerful abilities. Exgal only goes down when Boki combines all three abilities and... um... well, [[spoiler:seemingly summons Azathoth]]. Whatever actually happened, it was something that [[DivideByZero crashes the entire training simulation]] and wasn't even supposed to be possible. Afterward, if you try to view Exgal's data in the enemy list, it corrupts the interface and makes everything unreadable. This was apparently a ''watered-down'' version of something Boki will have to fight if she ever completes her training.
* ''VideoGame/CustomRobo'' on the Gamecube has Rahu, the BigBad. Originally an intangible force of destruction that annihilated anything it came across and very nearly caused TheEndOfTheWorldAsWeKnowIt, 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.
* ''VideoGame/DarkSouls'':
** The Bed of Chaos is a tree-like monstrosity that came about from a failed experiment to preserve the dying world's beacon of light, the First Flame. Instead of creating a new fire, the Witch of Izalith spawned what would eventually consume her and some of her daughters, as well as [[MotherOfAThousandYoung spawn every single demon in existence]].
** Manus, the Father of the Abyss. The true embodiment of the darkness that dwells within [[spoiler:all descendants of the Furtive Pygmy]], he's an insane, ape-like creature who wields the power of the world-destroying Abyss and corrupts everything around him, firmly establishing himself as the Squid in ''Dark Souls''[='=]s AngelsDevilsAndSquid scenario. The fact that [[spoiler:he was originally human]] hints at the terrifying idea that [[spoiler:all humans have the potential to transform into mindless, superpowerful abominations like Manus if they cannot control the shard of the Dark Soul they inherited from the Furtive Pygmy]].
** ''VideoGame/DarkSoulsII'' adds the Rotten, a grotesque amalgamation of writhing bodies that is said to have acquired a Wondrous Soul on its own, something that is said to be impossible. It conveniently resides in the deepest reaches of Drangleic, with nothing to care for except the rejects that fell down all the way to the Gutter.
** The Second game also contains the Darklurker, a bizarre, angelic being that exists at the deepest point of the Dark Chasm of Old (aka the Abyss). Said Chasm is an EldritchLocation that can only be reached through dark portals, and ''nothing whatsoever'' is explained about the Darklurker, with even its soul description saying "[[ThingsManWasNotMeantToKnow Some things are better off left unilluminated]]".
** ''VideoGame/DarkSoulsIII'' adds Aldrich, who is originally called "The Saint of the Deep", but later another name for him is revealed: "The Devourer of Gods". That title isn't just for show; when you find him, [[spoiler:he's in the midst of consuming Gwyndolin, the Dark Sun of Anor Londo]], and he wields abilities previously only used by gods in the series ([[spoiler:such as Nito's Gravelord Sword, Priscilla's Lifehunt Scythe, and Gwyndolin's magic arrow spam]]). Aldrich himself used to be human, but after eating many people he "softened and bloated" into a large, mobile pile of black sludge. Despite this, his power is enormous, as he [[CannibalismSuperpower absorbs the power of those he consumes]].
* ''VideoGame/DarkestDungeon'' has eldritch horrors erupting across an ancestral family's estate. The game's setting is partly inspired by Lovecraft's works.
* ''VideoGame/DawnOfWar'':
** The two [[TheLegionsOfHell Daemons of Chaos]], Ulkair and the unnamed Daemon of Khorne. Even [[SealedEvilInACan sealed]] both of them [[TheCorruption drive the populations of whole planets to madness]] before sucking the planet itself into [[HyperspaceIsAScaryPlace the warp]], and are completely impossible to kill. The former's defeat only sealed him back into the planet, while the latter is ''never'' fought directly, only the [[OneWingedAngel Daemon Princes]] it creates by imbuing loyal followers with its power.
** The [[HordeOfAlienLocusts Tyranid]] campaign of ''Retribution'' has the player ''take orders'' from one, eventually leading to a CosmicHorrorStory [[http://www.youtube.com/watch?v=rC7HFtB5e5k ending]]. Well, "take orders" in the sense that you receive barely comprehensible flashes of emotions and intent from a galaxy-sized HiveMind. ''"psychic beacon... antithesis... presence felt... darkens way... descend... Destroy... must clear way..."''
* ''Videogame/DeadByDaylight'' has the Entity, which the killers sacrifice the survivors to for an unknown purpose. In game, the Entity is never seen in full, though it has spider-like limbs to snatch up hooked corpses.
* ''VideoGame/DeadSpace2'' has [[spoiler:The Marker]], while ''VideoGame/DeadSpace3'' has [[spoiler:The Moon (and its brethren). It is the BiggerBad of the entire series, manipulating everyone for centuries through the Markers to restore its full strength.]]
* ''VideoGame/DefenseOfTheAncients'' has quite a few among the Dire heroes. ''VideoGame/{{Dota 2}}'' ups it by giving every hero a new, designed-from-scratch look to reflect their backstory. [[NamesToRunAwayFromReallyFast Atropos, the Bane Elemental]] is one of the most nightmare-inducing heroes, both in [[EyelessFace his]] [[OurCentaursAreDifferent appea]][[SpiderLimbs rance]] and [[MindRape means]] [[RealityBleed of]] [[MadnessMantra attack]]. [[PlaceBeyondTime Darkterror]], [[TheBlank the Faceless Void]], [[AnIcePerson Kaldr]], [[YouCannotGraspTheTrueForm the Ancient Apparition]] and [[VoiceOfTheLegion Nevermore]], [[YouWillBeAssimilated the Shadow Fiend]], and Enigma (a living black hole) aren't falling far behind. [[OurFairiesAreDifferent Puck, the Faerie]] [[OurDragonsAreDifferent Dragon]] is this if you leave out the [[GoodIsNotNice Radiant affinity]] and [[ReallySevenHundredYearsOld childish behavior]]. Worth noting are also the titular Ancients, beings of such immense power they were locked up in a moon by the creators of the world for thousands of years, and when the moon broke, the fragments filled with their power started changing the land and recruiting heroes who will fight, die, ressurect, fight and die again out of sheer fanaticism for these hunks of moon rock.
** Enigma is probably the truest to this idea - a TimeAbyss with no bio
* The Old One from ''VideoGame/DemonsSouls''.
* ''VideoGame/DevilSurvivor2'': The Septentriones. Considering they're [[WholePlotReference likely inspired]] by ''Anime/NeonGenesisEvangelion'', not really surprising.
* ''VideoGame/DiscworldNoir'': [[spoiler: Nylonathotep]].
* ''Franchise/{{Disgaea}}''
** Baal is just as old as the universe, absurdly powerful, and immortal.
** It's implied that the most ridiculously powerful of ''Disgaea'' [[OurDemonsAreDifferent demons]] start to turn into these. [[spoiler:The true Overlord Zenon]] was becoming a completely inhuman (so to speak) OmnicidalManiac and had to turn to {{Reincarnation}} for a way out.
** This is a surprise in ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'' when you realize that Mao [[spoiler:looks a whole lot more like his father than initially implied.]]
** ''VideoGame/{{Disgaea 4|APromiseUnforgotten}}'' has you say hello to Death/Extermination Submersible Combat Organism --aka [[http://static.tvtropes.org/pmwiki/pub/images/Desco_6996.jpg Desco]], the cutest widdle eldritch abomination that ever wanted to be the FinalBoss. Just because she's {{moe}}, doesn't mean she's incapable of turning you into a gibbering mass of fear and insanity, if [[http://static.tvtropes.org/pmwiki/pub/images/yogsothoth_3263.JPG her attacks]] are anything to go by.
* ''VideoGame/{{DownWell}}'' [[spoiler: has one for the final boss.]]
* ''VideoGame/DragonAgeInquisition'': [[spoiler:The Titans from the ''Descent'' DLC are incomprehensibly large beings that dwell deep beneath the surface of Thedas, and are actually the source of all lyrium, since it is in fact their blood. They share a unique psychic bond with all dwarves, indicating some form of latent HiveMind. They're also clearly sentient, and are privy to unknown secrets about what lies beneath Thedas, and have unexplained powers that allow their thralls to seemingly teleport at will throughout the world]]. In short, everything about them essentially slaps ''some'' well-accepted fact in [[ConstructedWorld Thedas]] in the face.
* In ''VideoGame/{{Drakengard}}'', TheWorldIsAlwaysDoomed because the gods are [[GodIsEvil not just evil]], but also composed entirely of {{Eldritch Abomination}}s. There are not slithering masses of tentacles that cause insanity by their very sight, but [[HumanoidAbomination 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 ([[spoiler:due to a supernatural disease they brought with them]]) that humanity is driven to near-extinction, AKA the world of ''VideoGame/NieR''. Which itself has more than its share of abominations as a result. ''Videogame/{{Drakengard 3}}'' reveals that the Grotesquerie Queens were originally [[spoiler:the Intoners, beings created by a magical flower. One in particular is revealed to be the goddess of the Cult of the Watchers, deified by her OppositeSexClone after he went mad.]]
* ''Franchise/TheElderScrolls'':
** House Dagoth in ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]''. Aside from the betentacled monstrosities and fleshy growths that tend to happen around their bases Dagoth Ur, their lord and master, is actually very much steeped in dream-imagery as he sleeps awake at Red Mountain. "The Dreamer Is Awake" is often found scrawled by the mad cultists in their strongholds. The implication is that Dagoth Ur has discovered an unspeakably dangerous middle-ground between CHIM, Amaranth and Zero-Sum where he exists in a godlike state because of his awareness of Anu's Dream but, unlike CHIM where he exists as one with it and maintains his own individuality, Amaranth where he exits the Dream to make his own or Zero-Sum where he simply fades into the Dream ''Dagoth Ur's twisted, traumatized and broken mind is being imprinted on the Dream of Anu.'' Through Corprus, the manifestation of Dagoth's will, he is turning Anu's Dream into his own.
** Later games attempted to pass Sithis off as a more traditional god of death, but the backstory reveals that he is a great void, the undying soul of a dead primordial force. [[MindScrew Sithis Is Not.]]
** The Daedric Princes are alien beyond human understanding, though they can take any form they like, and so will often [[AFormYouAreComfortableWith take a humanoid form to deal with mortals.]] Gender has no actual meaning to them and some appear as female, but they are referred to as "princes" as a whole. (One of them, Hermaeus Mora, doesn't bother with this and resembles a more typical abomination.) [[BlueAndOrangeMorality They don't share the sense of "good" and "evil" mortals have]]. 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, but all of them have demonstrated a willingness to reward mortals they find particularly helpful, loyal, or amusing.
*** Hermaeus Mora ditches any semblance of sanity in ''Skyrim'' and appears as a "Wretched Abyss" -- a living dark vortex. In [[spoiler:the ''Dragonborn'' DLC]], he appears in a truly mind shattering form with a seemingly infinite amount of tentacles and eyes.
** Alduin, BigBad of ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''. He's a PhysicalGod who [[spoiler:is capable of eating the souls of the dead in Sovengarde and the only thing that can stop him is an Elder Scroll or The Dragonborn himself]]. There's a reason he's called "World Eater"; he was born to destroy the world.
*** The other Dragons are no less strange. The BreathWeapon a dragon uses against you? That isn't some magic or natural flame. That is the dragon [[WordsCanBreakMyBones shouting the word "fire" at you]] in their native tongue. Their immortality? It might be due to the fact that they exist outside the effects of time. [[spoiler: The very ''concept'' of "finite", "mortality" or "entropy" is harmful to them. They might not even be truly dragons, but physical manifestations of aspects of the God of Time, Akatosh. Thus, they may be more like demons or angels than traditional dragons]]. They also can't be killed by anyone but the Dragonborn, a person born with the soul of a dragon, who can absorb their souls. This, along with his/her ability to use the dragon's language without the lifetime of training most mortals require indicates that the Dragonborn might even qualify as a HumanoidAbomination.
** There's also the Hist. The Hist are multidimensional hive-minded trees of unknown origin (though they are implied to be remnants from a previous cycle of time/iteration of the universe) that travel through space, have no concept of linear time, are able to mentally influence and physically alter organisms who consume their sap, and are completely alien and incomprehensible ''even to those who have achieved CHIM'' (a state of what is essentially awake lucid dreaming that can alter reality, and a full understanding of the universe), something which can't even be said about the likes of Hermaeus Mora.
* The third ''VideoGame/EpicBattleFantasy'' game's main villain, Akron. Awakening him causes even the area around him to undergo drastic effects: the farther location is implied to become an errupting LethalLavaLand, while the points closer to him are outright made into a [[EldritchLocation very bizarre]] space area with a black hole behind him.
* In ''VideoGame/EpicMickey'', 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.
* ''VideoGame/EternalDarkness: Sanity's Requiem'' takes one of the most interesting twists, as [[spoiler:the most powerful Ancient, Mantorok the Corpse God, is actually mildly fond of humanity, even serving as a fertility god in a small village in Cambodia]]. He's ultimately responsible for the main character's [[spoiler:destruction of the "evil" Ancients, using the Roivas family to kill three of the other Ancients in three separate timelines and then merging those timelines together]]. Denis Dyack, who founded Silicon Knights, the company behind ''Eternal Darkness'', [[http://www.escapistmagazine.com/articles/view/issues/issue_60/356-Theres-a-Lot-More-to-Tell.3 confirmed in an interview]] that yellow is definitely the colour of a fifth Ancient, supposedly [[spoiler:the equal-but-opposite of Mantorok.]]
* EVERY SINGLE TrueFinalBoss in the ''VideoGame/EtrianOdyssey'' series. [[BonusBoss The one]] in the third game [[YouCannotGraspTheTrueForm takes the cake]]. [[https://www.youtube.com/watch?v=A16h1BwsFyE Just try to count all those eyes and tentacles...]]
* ''VideoGame/{{Everlong}}'' has Pandemonium and the Ultimate Weapon.
* In ''VideoGame/{{Eversion}}'', a major character is one. In the bad ending, [[spoiler:she eats you]]. In the ''good'' ending, [[spoiler:[[TomatoInTheMirror you're one, too]]]]. Not as surprising as you might think, given [[EldritchLocation what he does]] to the world.
* In ''Videogame/{{Evolve}}'', this is the true nature of [[spoiler: the monsters. They are the manifestations of a largely unknown force, likened to a 3D being pressing against a 2D universe. Their forms are created by drawing on the subconscious fears of humans, fears that they themselves may have created millennia ago. Killing one merely destroys that manifestation, forcing it back to its dimension of origin until it can remanifest from an egg, which are self-contained interdimensional gates. The monsters themselves can sense dimensional distortions and have limited telepathy, while their genetic code somehow involves the equation used for the reality warping tech of the humans. All of this is meant to perpetuate their end goal: to change the base energy state of the universe to a more stable one, annihilating everything in the process.]]
* ''VideoGame/{{Fable}}''
** ''VideoGame/{{Fable|I}}'s'' Jack of Blades [[spoiler:and the rest of the Court]], given their origins lie in a realm referred to as The Void and his form seems entirely dependent on [[spoiler:his host body]].
** ''VideoGame/FableIII'' introduces [[spoiler:the Crawler.]]
** ''VideoGame/FableTheJourney'' reveals [[spoiler:ones which come from the same source as the Crawler: the removal of the Void/Court induced wasting illness of William Black the human who defeated Jack of Blades and the rest of the Court (the illness came from fighting the Court in the first place).]]
* ''[[VideoGame/FallenLondon Fallen London]]'s'' world has a whole variety of them, including sentient stars, giant space crabs, cthulhu-looking humanoids, and a nomadic mountain that shouts at you in an [[BrownNote eldritch language]].
* One of the religions in the ''VideoGame/{{Civilization}}'' mod ''VideoGame/FallFromHeaven'' is called Octopus Overlords. The priests use homeless people as channels of the will of the Overlords. The unfortunates GoMadFromTheRevelation, which works just fine for the priests, as they are unable to alter what they "hear". One of the things the Overlords teach their followers is how to turn people into zombie-like creatures by drowning them. Interestingly, one of the heroes given to civilizations that follow this religion is said to be the origin of the Overlords, as he has the uncontrollable ability to make his dreams real.
* One of the chief reasons ''FatalFrame'' is so scary is that it avoids this trope: all the ghosts are humanoid and [[UncannyValley 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... [[https://www.youtube.com/watch?v=0F3wSeTF9UI 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.
* In the ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]'' games, [[HumanoidAbomination 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 [[spoiler:Harlan Wade releases her from the Vault]]. 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.
* ''Franchise/FinalFantasy''
** The creature [[http://finalfantasy.wikia.com/wiki/Omega_%28enemy%29 Omega]] is a reoccurring super-boss in many ''Final Fantasy'' games. Originally it was just a powerful machine that, according to ''Final Fantasy'' lore, would just randomly attack things that got near it. More recent games and story expand on Omega's back-story and imply that the different versions of Omega in other ''Final Fantasy'' games are in fact the same thing and Omega really exists across multiple universes with [[AFormYouAreComfortableWith a shape that conforms]] to the laws and rules of said universe. Also, one story states that Omega is supposed to kill a powerful foe whom most assume to be Shinryu, a powerful god-dragon that also exists across multiple universes.
*** Seriously, one of the game quotes for this this thing is: "From the sky it comes, heartless and bloodless—Omega, Bringer of the End! Unleash your might in the name of destruction... and may all men know despair!"
** Chaos from the original ''[[VideoGame/FinalFantasyI Final Fantasy]]'' is an Eldritch Abomination created by an endless time loop.
** Cloud of Darkness from ''VideoGame/FinalFantasyIII'': ExactlyWhatItSaysOnTheTin.
** Zeromus in ''VideoGame/FinalFantasyIV'' is more or less the AnthropomorphicPersonification of hatred, borne from the soul of an evil wizard. [[http://www.videogamesprites.net/FinalFantasy4/Bosses/Zeromus2.gif And he looks like this.]]
** Exdeath in ''VideoGame/FinalFantasyV''. He just plain is the part normally and really looks it [[spoiler: in his ultimate Tree form at the final battle and as Neo Exdeath.]] He was born from an aggregate of evil souls sealed into a sacred tree, and later becomes an embodiment of The Void.
*** Those nameless... ''things'' that lurk below the ocean floor.
** Kefka from ''VideoGame/FinalFantasyVI'', [[spoiler:once he absorbed the three goddesses]], stands atop a large tower of human flesh and organs whose floors represent the levels in Dante's Divine Comedy.
** Jenova from ''VideoGame/FinalFantasyVII'', an {{Expy}} of the creature from ''Film/TheThing1982'' and conceptual sibling to [[VideoGame/ChronoTrigger Lavos]]. Jenova has no set form, and mimics the appearance of its prey; in this case, the vague outline of a woman, with missing limbs and [[EyesDoNotBelongThere eyeballs in place of nipples]]. Its descent marked the downfall of the [[{{Precursors}} Cetra civilization]]. By extension, Sephiroth - the fruit of a project to create Jenova-infused superbabies - is [[HalfHumanHybrid half-human]], half-Eldritch Abomination.
*** The [=WEAPONs=] are Antieldritch Unabominations. [[AllThereInTheManual In the backstory of the game]], these creatures are the [[GaiasVengeance all-natural guardians of the Planet]][=/=]TheLifestream (your mileage may vary if the Lifestream can count as an eldritch entity). Unfortunately, humanity has [[HumansAreBastards proven itself dangerous]] to the Planet, so they went aggro on human cities.
** Xagor of ''[[VideoGame/SaGa3 Final Fantasy Legend 3]]'', which resemble nothing more than a mass of flailing tentacles and fanged mouths.
** In ''VideoGame/FinalFantasyIX'', Necron fits this to a T, with the effect being accentuated by horrific [[http://www.youtube.com/watch?v=62MkCz0f83s scenery and music]]. 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 [[http://www.youtube.com/watch?v=_HM7kgvbr2E Ozma]]. Like Necron, it happens to be a GiantSpaceFleaFromNowhere.
** In ''VideoGame/FinalFantasyX'', Sin is a giant monster the size of a city that emerges from the depths of the ocean to completely annihilate all settlements larger than small villages at random intervals and terrorized Spira for a thousand years. Even if it is defeated by a High Summoner, [[spoiler:by sacrificing himself and his friends]], it returns a few years later [[spoiler:by reincarnating from the body of the High Summoner's closest friend]] 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.
*** [[spoiler:Yu Yevon and The Final Aeon]]. The former is the still lingering sentiment of a long dead summoner who frequently possesses Aeons for the purpose of destroying the world and is the unholy will [[spoiler:powering Sin]]. The latter, while benevolent (usually), is powerful, and its warped form is [[PoweredByAForsakenChild crafted from the loving sacrifice of a Guardian for his/her Summoner]]. An example is [[spoiler:Seymour]]'s Anima, whose domain is ''pain''.
** ''VideoGame/FinalFantasyXII'' has all of the summonable Espers, being based on a mix of [[VideoGame/FinalFantasyTactics Lucavi]] and past final bosses.
** ''VideoGame/FinalFantasyXI'' brings back Atomos, everyone's favorite inter-dimensional nightmare from V and IX. This time, [[spoiler:it is actually quite capable of devouring a timeline.]]
** The world of Ivalice in ''VideoGame/FinalFantasyXII'' 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 the final boss of the sequel DS game, the Occuria...
** The Fal'Cie from ''VideoGame/FinalFantasyXIII'' are also this, despite looking for the most part like bizarre machine-things.
*** In [[VideoGame/FinalFantasyXIII2 the sequel]] there's Gogmagog, an abomination that the above mentioned Fal'Cie had to throw out of the time-space continuum to be rid of.
* ''VideoGame/FinalFantasyTacticsA2'' has [[spoiler:the Neukhia, whose presence is so dangerously poweful, even having a LIMB in Ivalice presents an apocalyptic threat]]
* ''VideoGame/FiveNightsAtFreddys'' franchise:
** The Golden Freddy. In the first game, it appears inside your office (even if both doors are closed) if you see its face on a poster, like it teleported inside. If this strange creature appears, it'll make you hallucinate for a few seconds before it suddenly appears in your face and kills you. It doesn't cause a standard game over; it just crashes the game. Because of this, it was theorized to be a mere hallucination... until the second game came out, and not only is was confirmed to be real (since it is the TrueFinalBoss), the thing can and really ''does'' teleport into your office, ''whenever it wants'', and when it enters your office, it will stare at you for a few seconds, only to '''fade from existence before your eyes''', and then summon its head (not the whole body, just ''a head, a flying head'') and throw it at you, and then you die. Oh, and if it doesn't just teleport to your office, it will come to visit you through your door in the form of ''a gigantic, flying head the size of his whole body''. Despite all of this, the thing's origin is surprisingly tragic: [[spoiler:it is just possessed by the ghost of a murdered child]].
** The Puppet. Its mere existence is nothing sort of unworldly: [[spoiler:It is supposed to be the ghost of the first child murdered, and, for some reason, he is capable of possessing a marionette. The horror comes from the fact that all other animatronics, are only possessed by spirits of children because The Puppet trapped their souls in the animatronics]]. The key word there is [[spoiler:"supposed"]]. According to the fourth game, [[spoiler:there are some possibilities that it has been abnormal even before it was possessed]].
** Speaking of the fourth game, ALL the animatronics become this, dubbed "Nightmare (animatronic's name)". Their appearances are horrifyingly twisted, with BodyHorror and MoreTeethThanTheOsmondFamily thrown in. Special mention go to Nightmarionette(or Nightmarionne), the Nightmare version of the Puppet. Its appearance...well, [[http://i7.photobucket.com/albums/y278/kazokuhouou/deargod_zpsaiwzgstu.png just]] [[http://i7.photobucket.com/albums/y278/kazokuhouou/why_zpslnahoiqc.png see]] [[http://i7.photobucket.com/albums/y278/kazokuhouou/effoff_zpsjvlqvukt.png for]] [[http://i7.photobucket.com/albums/y278/kazokuhouou/seriouslyeffoff_zps5acuneh6.png yourself]].
* ''VideoGame/FreeSpace''
** In one fan-made campaign for ''Free Space 2'', ''Transcend'', the BigBad 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 [[spoiler:the Transcendant was originally human and was somehow expelled from the physical universe, growing into an EldritchAbomination, then attempted to return home only to very nearly ''break the universe'' in the process. He did none of this on purpose either, being pretty well insane by the time he attempted to re-enter reality. All you hear from him directly is his static-broken voice over your radio begging for help... and thanking you when you finally kill him.]]
** In the ''VideoGame/FreeSpace2'' mod ''Blue Planet'' the Shivans appear to follow this trope, as they are [[spoiler:implied to be immortal and eternal, transcending universes, not so much a species as a facet or function of the fabric of reality itself]]. One sequence has the main character [[spoiler:psychically connect with them]], which places enormous strain on the mind. The main danger in the mission is to prevent the character from being driven irreversibly insane by what she's seeing.
* ''[[VideoGame/GodOfWar God of War: Ascension]]'' has one in its final boss, [[spoiler: Alecto]]'s true form.
* ''VideoGame/{{Gradius}}'' has [[BigBad Bacterion]], an alien entity from AnotherDimension that endlessly reproduces and spreads its biomass, to the point that it can and has consumed entire planets into its HiveMind. Worse, killing it permanently would require the complete extermination of all Bacterian cells in the universe: if even one survives, it will eventually regrow into a new Bacterion (might take a few hundred years, though). Bacterion can also transform other creatures into beings like itself, with the same abilities: it has done so to [[TheDragon Dr. Venom]], [[DragonAscendant Gofer]], and [[PlanetEater Zelos]], the last of which was already pretty eldritch on its own. There's also the mysterious creature "Original Visions of Ultimate Monsters" (O.V.U.M.) from ''Gradius Gaiden'', a shapeshifter that may be another piece of Bacterion, or something else altogether.
* ''VideoGame/GreyGoo'' has The Silence. It's enough of a threat to make an assimilating nanobot go from "explore and map the stars and report back signs of (sentient) life to humans" to "this thing has to be stopped or EVERYONE DIES". This thing has apparently [[TheStarsAreGoingOut devoured countless stars]] and is covering a major percentage of the universe. The goo is trying to grow to such proportions to stop it, The Silence devouring everything in its wake. The Beta/Morra claim that everything has a song or story to share, including the goo, originally just an exploration probe. And guess what is the only thing not to have one? [[https://static.greybox.com/static/media/uploads/gg2_galaxy.jpg It's also making a beeline straight for Earth.]] All of Silent Space is part of it's mass. It may come from Ecosystem Psi (making it a Pandora's Box) or from outside our galaxy -- which brings the question how much of the UNIVERSE has it already devoured?
* ''VideoGame/GuildWars'':
** [[http://wiki.guildwars.com/wiki/Abaddon Abaddon]], the God of Secrets.
** As of ''VideoGame/GuildWars2'' there is the six Elder Dragons. Each of which essentially embodies one of the worlds elements. Water, Earth, Ice (winter in general), Fire (Lava), Death (Undeath), and Crystal. [[spoiler:Together these six monstrosities were responsible for the extinction of almost all life on Tyria in the previous age. Only a handful of races survived. Their touch brings corruption of all life that comes into contact with them (with the exception of the Sylvari).]] While they may not be insanity incarnate, they certainly are chaos incarnate.
* ''[[Franchise/DotHack .hack//]]''
** Cubia. Okay, sure, it's a computer program, but within the realm of The World it's referred to as "The Anti-Existence", specifically [[spoiler:of the Twilight Bracelet/the avatars (which are the same things in different forms). As long as they exist, Cubia will exist as well]]. All of the other [=AIs=] running about seem to have some purpose that they're trying to accomplish, but Cubia pops up out of ''nowhere'', and 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 the heroes are understandably reluctant to use.
** [[spoiler:Morganna]] is called [[TheOldGods "Old God"]] in-universe. Before Aura's birth she was the core of The World itself, and is never actually seen in the games in a form of her own, which gives her that NothingIsScarier and UltimateEvil effect. When she actually does take action, it's through the Phases, which qualify as lesser Abominations themselves.
* The [=GMan=] of ''VideoGame/{{Half-Life}}'' is many magnitudes more powerful than anything else in the series, casually freezing or warping time and stepping into scenes as if through the fourth wall, and required the ''entire Vortigaunt race'' working together to even stall him (which didn't last long). He at least [[HumanoidAbomination appears human]], but is neck deep in the UncannyValley (such as being the only character whose face is perfectly symmetrical) and generally behaves as if he studied human speech and mannerisms without having any idea how they actually work.
* ''VideoGame/TheHalloweenHack'' is packed full of them, both enemies and bosses alike. Starting when Varik enters deep in the heart of Twoson's sewers. The Desire Dog is one particularly hideous and disturbing creature, with [[{{Squick}} melting, dripping, oozing tentacles]] for a face.
* ''Franchise/{{Halo}}'':
** The Flood are a {{Hive Mind}}ed [[TheVirus parasitic entity]] of such ancient, alien power that even the near god-like [[{{Precursors}} Forerunners]] were ultimately forced to sterilize a galaxy to put them down... and they eventually rose up again, with their Gravemind calmly pointing out right after their second defeat that this victory will simply delay the inevitable.
** The Gravemind on its own: a vast, immortal, reincarnating intelligence. Its physical form is a vast Flood hive full of tentacles and accumulated biomass. If this body is destroyed, it can rebuild itself if but one Flood spore survives, ''anywhere''. 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 [[ArcNumber heptameter]] and morbid metaphors and you have one creepy abomination.
** The Charum Hakkor Prisoner from the ''Literature/TheForerunnerSaga'' trilogy. Described as a [[spoiler:huge, misshapen humanoid with four arms and compound eyes on an indescribably ugly face. And to top it all off, it's a [[RecursivePrecursors Precursor to the Forerunners themselves]], with its kind having ''created the Flood''.]] It's later revealed that [[spoiler:the Prisoner itself ''[[WhamEpisode is a Gravemind]]''.]]
** The series delves even further to reveal the Flood's origins: [[spoiler:they are in fact the Precursors themselves, who have mutated themselves into the Flood so they can have their revenge on the Forerunners and all of their other creations]]. ''Literature/HaloSilentium'' shows the Precursors themselves to be this full out: incomprehensibly complex beings that can take nearly any form they wish, physical or even incorporeal, [[spoiler: from the HiveMind Flood, to the monster imprisoned on Charum Hakkor]]. Their morals and thought patterns are utterly alien (the Didact put it best: "The concept of will, good or ill, is irrelevant when speaking of such beings"), they're driven by an intrinsic need to create other beings, [[spoiler: they're ''pissed'' at the Forerunners for wiping them out (which they only managed because the Precursors were simply too busy ''marveling'' at the violence to defend themselves)]], and [[spoiler:they're implied to be even older than ''the universe itself'']]. Even their insanely advanced technology is nigh-incomprehensible, being apparently made out of ''thought''.
* The Serpent Riders from the ''VideoGame/{{Heretic}}'' and ''VideoGame/{{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-[[Franchise/{{Alien}} 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.)
* TheVirus in ''VideoGame/HomeworldCataclysm''. The local {{Precursors}} apparently picked it up in [[SubspaceOrHyperspace subspace]] and disabled their ship in an attempt to [[SealedEvilInACan contain it]]. They failed, obviously, and once it was released it [[TheAssimilator assimilated]] everything it could find, from people to entire ships, absorbing it all into one colossal galaxy-wide HiveMind with the aim of assimilating ''everything''.
* The {{Roguelike}} ''Videogame/{{Incursion}}'' has among its pantheon [[http://www.incursion-roguelike.org/man/Pantheon.html#KY Kysul]], the Watcher Beneath the Waves, an unspeakably ancient and foreign being from a long-dead world, keeper of eldritch, [[GoMadFromTheRevelation mind-shattering secrets]], whose mere form is so alien that [[BrownNote it can cause insanity in the unprepared]]. It is also, in a spectacular [[SubvertedTrope subversion]] of the expected attitudes of such a creature, strongly LawfulGood.
* ''VideoGame/InsanelyTwistedShadowPlanet'' was created by a small EldritchAbomination that ''assimilated the Sun'' and turned it into a bio-mechanical-shadow-like monstrosity. [[spoiler: You can unlock a movie that details the origins of a much greater being that assimilated his entire ''Star System'' and now sends his seeds to others. That thing you defeated? [[OhCrap That was only one of those seeds]]]].
* ''VideoGame/JadeEmpire''
** Following the destruction of Dirge and [[spoiler:the desecration of the Water Dragon's body and spirit]], 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 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.
* ''Franchise/JakAndDaxter''
** ''VideoGame/Jak3Wastelander'' has the Dark Makers, which are [[spoiler:Precursors corrupted by dark eco.]]
** The Metal Head Leader from ''VideoGame/JakIIRenegade''.
* As far as we know, ''Videogame/KerbalSpaceProgram'' doesn't actually have any of these. However, a certain series of bugs that caused spaceship parts to flail like crazy, accelerate in weird directions without any reason, and even spontaneously implode, without going over [[BodyHorror what it does to unprotected Kerbals]] was called the Deep Space Kraken, with any and all spaceships and Kerbals who died to the bugs being devoured by it. The name stuck, and any similar bug that came in after the original was fixed has been blamed on this creature.
* ''VideoGame/KidIcarusUprising'' has monsters such as Ornes, [[spoiler:the Chaos Kin (to a lesser extent), and the Soul-Eating Monster.]]
* ''Franchise/KingdomHearts''
** TheHeartless, 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 [[AsLongAsThereIsEvil they come from the darkness in people's hearts.]] 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 [[EmptyShell Nobodies]]. 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. They're also not all bad, Roxas and Namine being genuinely nice and Axel, while not strictly good all the time, has good in him. [[spoiler:It's also, oddly, a temporary ailment, as the void can naturally be filled with a new heart overtime.]]
** 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 to dark emotions such as anger or jealousy.
** [[spoiler:Xion]] is halfway between this and HumanoidAbomination, 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.
*** Case in point, most members of Organization XIII see [[spoiler:Xion]] as a girl in a hood. Xigbar sees [[spoiler:Xion]] as someone his Other encountered before becoming a Nobody, [[spoiler:Ventus]]. Roxas and Axel both see [[spoiler:Xion]] as an unhooded version of the hooded girl, with a face and voice matching Kairi, only with black hair. Xemnas on the other hand sees his [[spoiler:No. ''i'']] as the form he intended them to be: [[spoiler:a perfect copy of Sora]].
* ''VideoGame/KingdomOfLoathing''
** The 2008 Crimbo event resulted in [[http://kol.coldfront.net/thekolwiki/index.php/The_Crimbomination the Crimbomination]]. It's also about as unbeatable as a typical EldritchAbomination, no [[DidYouJustPunchOutCthulhu punching out Cthulhu here]]. [[http://kol.coldfront.net/thekolwiki/index.php/Ho-ho-ho-hee-hee-hee-ha-ha-ha-ha-ha-ha-ha! Even the guard that was assigned to the factory has been driven completely insane just from looking at it]]. It was created by human hands, or at least by [[EverythingsBetterWithPenguins 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 [[GreenRocks grimicite]], which is highly radioactive and caused the elves to mutate. After curing a lot of elves of their mutation, the remaining mutated elves [[FusionDance fused together]] to create the Crimbomination. The Kingdom's adventurers were able to weaken it to the point where the penguins could [[SealedEvilInACan 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 the new Uncle Crimbo, and it showed up in the 2010 Crimbo event... as a CorruptCorporateExecutive running the bland, soulless corporation CRIMBCO.
** There is also [[http://kol.coldfront.net/thekolwiki/index.php/Squamous_Gibberer the Squamous Gibberer]], a fragment of a horrible monster from beyond reality who whispers horrible secrets and paranoia-inducing mutterings straight into your mind. Who happens to be [[DidWeJustHaveTeaWithCthulhu a pretty useful familiar]].
** [[EldritchLocation The Caliginous Abyss]] is an end-game zone at the bottom of the Sea, infested with horrible eldritch monsters such as [[http://kol.coldfront.net/thekolwiki/index.php/School_of_many the school of many]]. The closest thing to a joke down here is the SurrealHorror of fighting [[http://kol.coldfront.net/thekolwiki/index.php/Peanut an evil Mr. Peanut look-alike]], and motherly admonitions like "COMB YOUR HAIR. YOU LOOK LIKE A HIPPY" appearing on the landscape.
** The end of the Sea questline has you face one of two elder gods of the Mer-Kin: Shub-Jigguwat, the Elder God of Violence (who resembles a giant suit of animated armor super-charged with electricity), and Yog-Urt, the Elder Goddess of Hate (who resembles a giant floating ball of flesh with a huge mouth whose inside is a void emptier than the vacuum of space).
** [[spoiler:And let's not even talk about the real final boss of the Sea questline; [[http://kol.coldfront.net/thekolwiki/index.php/Dad_Sea_Monkee Dad Sea Monkee]] hooked up to a reality-bending, perception-warping, quite literally indescribable machine.]]
-->[[spoiler:The room is the machine occupies the room contains the machine contains the room describes the machine creates the room is the machine.]]
** In Crimbo 2015, [[spoiler: the "Earth Mother" the hippy elves are summoning turns out to be Gaia'ajh-dsli Ak'lwej, who's less "benevolent spirit of nature" and more "primordial elemental monstrosity"; it's a hundred feet tall, it has "[[ExtraEyes every kind of eye]]" on its face, and its body is made of a mish-mash of stone, flesh, and plant matter.]]
* ''Franchise/{{Kirby}}''
** Dark Matter is an immensely powerful, formless being of evil that corrupts all it touches and is completely invincible, except to special weapons. Further, judging by how often it's reappeared, it appears to be [[FightingAShadow impossible to permanently destroy]] and can only be temporarily defeated. It's [[VileVillainSaccharineShow even creepier when considering the setting]]. Thankfully, it's also far more ''defeatable'' than most major abominations. This is compounded in ''Kirby: Planet Robobot'', where a flawed clone of Dark Matter is created by the supercomputer Star Dream. Not only is it stated that trying to comprehend Dark Matter's form required essentially all of its computing power, it ''still'' can only create the swordsman form instead of Dark Matter's true form.
** Zero itself is the core of Dark Matter and is an entity that looks like a gigantic eyeball that has complete and utter control over Dark Matter. It later resurrects itself from death as a surreal-looking FallenAngel to fight Kirby again.
** Most ''Kirby'' final bosses are at least somewhat eldritch. Nightmare is the manifestation of everyone's bad dreams, Dark Mind from ''[[VideoGame/KirbyAndTheAmazingMirror The Amazing Mirror]]'' is an evil mirror demon, and Dark Nebula from ''[[VideoGame/KirbySqueakSquad Squeak Squad]]'' is [[SealedEvilInACan a sleeping Eldritch Abomination]] stated to be the ruler of the underworld.
** Kirby's proposed origin in [[Anime/KirbyRightBackAtYa the anime series]] more or less reveals that he himself is an Eldritch Abomination that went good, which explains a lot (though the anime is in an AlternateContinuity from the games). Gooey, his sidekick from ''[[VideoGame/KirbysDreamLand3 Dreamland 3]]'', is a piece of good Dark Matter, too.
* ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'':
** [[OmnicidalManiac Darth]] [[NamesToRunAwayFromReallyFast Nihilus]], who WasOnceAMan 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 he 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 ''[[spoiler:Force black hole]]''. Ultimately, it's this peculiarity that [[spoiler:allows the Exile to defeat Nihilus]].
* In ''VideoGame/LaMulana'', despite all the big, ugly bosses, the real award goes to [[spoiler:The Mother, who is actually the entire temple itself. It helps with the non-euclidean geometries of the temple, and the different areas have no correlation in how they are connected. Oh, and the fact that the Mother came from the sky and created life (e.g. us) in the hopes that it would find a way to return her there.]]
* ''VideoGame/LeagueOfLegends'' has quite a few of these as ''playable characters''.
** Cho'Gath, Kog'Maw, Kha'Zix, Vel'koz, and Rek'Sai are all extradimensional horrors from the [[EldritchLocation Void]], which is ''crawling'' with them, while Kassadin and Malzahar are humans who fell into the void and took power from it. One was irreparably changed by it and managed to keep his free will (and now fights against it), while the other became a willing slave to it.
** Fiddlesticks is an extraplanar being of pure fear who emerged as the result of a botched summoning ritual and was trapped inside a scarecrow.
** Xerath [[WasOnceAMan was a mage]] who performed an extremely dangerous ritual that transformed him into a monstrously powerful EnergyBeing of completely inhuman morality.
** Nocturne is a dream elemental of some sort who murdered Summoners in the dreamworld until he was dragged into the land of the awake.
** Lissandra was a human who sold herself to primal ice spirits and turned into a horrific elemental who, with their help, nearly brought about the end of the world centuries ago.
* The Elder God of ''VideoGame/LegacyOfKain'' 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 [[spoiler:little more than a parasite who feeds on the souls of the dead, masquerading as an omnipotent god to strike fear into the hearts of his servants.]]
* ''Franchise/TheLegendOfZelda''
** {{Big Bad}}s [[VideoGame/TheLegendOfZeldaMajorasMask Majora]], [[VideoGame/TheLegendOfZeldaLinksAwakening DethI]], and [[VideoGame/TheLegendOfZeldaPhantomHourglass Bellum]] seem to have some level of this. Particularly Majora, as it is completely unknown how the mask came to be. According to the manga, the mask is the remains of an old god (this works well with the fact that after each boss battle you get "[Boss]'s remains" which takes the form of their mask). This mask then started to MindRape the [[WoobieDestroyerOfWorlds sad lonely imp]] who started using it until he was its puppet to destroy the world. Majora's Mask made Skull Kid poison the water, create a never-ending winter, poison the ocean, and raise the dead. In the final confrontation, Majora abandons Skull Kid and posesses the Moon, at which point the Four Giants, the ancient protectors of Termina, can no longer withstand the power of the moon and begin to collapse underneath it. Then there's the boss battle itself, which can only be described as a psychedelic brawl.
** The Imprisoned [[spoiler:and its true form, Demise]], in ''[[VideoGame/TheLegendOfZeldaSkywardSword Skyward Sword]]''. However, Fi's analysis indicates that [[spoiler:Demise]] takes a different form every generation... [[spoiler:meaning even after it transforms, the form Link faces might not even be what it truly looks like]].
*** Which, by extension, would make [[spoiler:Demise's {{Reincarnation}}, Ganondorf,]] a HumanoidAbomination.
** Midna takes a bizarre and all immensely powerful form when using the fused shadow. The helmet turns her into a multi-armed trident wielding creature, somewhat larger than Ganon. The impression given when speaking to the spirit Lanayru is that the fused shadow is capable of breaking reality and the last time it was used he and the other spirits had to intervene and break it to prevent it's users in controlling the Triforce through its power.
* The Destroyer from ''VideoGame/TheLegendOfSpyro: Dawn Of The Dragon'' counts. It's an ancient mythological monster who's existed since the beginning of time. It exists for only one reason: to cause [[WorldWreckingWave 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 [[spoiler:to destroy every Dark Crystal in it's entire body, including flying inside it and blowing up its heart. That didn't stop it because Malefor, ChessMaster that he is, had a backup crystal ready just in case.]]
* Leave it to the designers of ''VideoGame/LittleBigPlanet 2'' to make an Eldritch Abomination out of a ''vacuum cleaner''! The Negativitron travels the cosmos, constantly sucking up all material in Craftworld. It can also be considered [[spoiler:an EldritchLocation]], too.
* Zophar, from ''VideoGame/LunarEternalBlue''. 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 manifests 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. [[NightmareRetardant He's substantially less scary-looking]] [[BishounenLine when he does get the power of Althena]]. His aims are still plenty terrifying, though.
* The Soulless Ones of ''{{VideoGame/Lusternia}}''. [[PsychoPrototype Prototypes]] of the eventual template used to create the [[PhysicalGod Elder Gods]], they were born without souls and exist solely to devour - Gods, infant Gods, mortals, nature spirits, animals, and each other. They [[CannibalismSuperpower 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 [[LoadBearingBoss take down the universe with them]], so they're sealed away. [[CardboardPrison For the time being]]...
* ''[[https://armorgames.com/play/3314/the-majesty-of-colors The Majesty of Colors]]'' allows you to play as one, demonstrating either VideoGameCrueltyPotential or VideoGameCaringPotential... Although, [[spoiler:it's AllJustADream in the end... OrWasItADream]]
* In ''VideoGame/ManaKhemiaAlchemistsOfAlrevis'', [[spoiler:the ''main character's'' wish-granting powers given "physical form"]] comes close. It was given a BonusBoss PaletteSwap [[NamesToRunAwayFromReallyFast called "Pain"]], described this way:
-->''The strongest, worst thing in the world. A concentrated mass of power, this being hints that the end of the world is near...''
* The W'rkncacnter from ''[[{{VideoGame/Marathon}} Marathon Infinity]]''. It is described as a being of pure chaotic energy that can [[RealityWarper warp reality]] and was sealed inside a star until released by the Pfhor by accident. It is believed that the alternate timelines the player character jumps to are due to the W'rkncacnter's influence.
* ''Franchise/MassEffect''
** Invoked by [[AbusivePrecursors The Reapers]], a bunch of {{Sapient Ship}}s who use gravity and {{mind manipulation}} technology to pass themselves off as incomprehensible gods from beyond dark space. They make a pretty good show of it, with Indoctrination working exactly like you'd expect someone having their mind corrupted by terrible beings from Beyond to work (with an ApocalypticLog in ''VideoGame/MassEffect2'' of someone falling victim to it reading like it came straight from the pen of Lovecraft himself), and they certainly have the attitude of something eldritch and unstoppable.
-->'''[[spoiler:Sovereign]]:''' [[AC:You touch my mind, fumbling in ignorance, incapable of understanding... you cannot even begin to comprehend the nature of our existence.]]
** Leviathan from the ''Leviathan DLC'', [[spoiler:TheRemnant of the species that created of the Reapers, and used similar [[MindRape manipulation]] to make all life in the Galaxy worship them as gods.]]
* ''VideoGame/MegaManZX'' brings us [[ArtifactOfDoom Model W]], the original [[TransformationTrinket Biometal]]. Created from the remains of the space station [[KillSat Ragnarok]], it is a sentient, twisted hunk of metal that [[MookMaker creates Mavericks]], [[WorldGoneMad warps the landscape around it into something out of nightmares]], and [[TheCorruption corrupts anyone who stays in contact with it for too long]]. [[spoiler:It's ultimate form, the {{Ouroboros}}, is what can only be described as a LivingShip [[WombLevel with pulsating insides]]]]. Fitting, [[spoiler:as the [[SoulJar intelligence within it is that of Dr. Weil]], arguably the evilest villain in Mega Man history]].
* ''VideoGame/MinecraftStoryMode'': [[spoiler: The Wither Storm, made by substituting one of the soul sand for a command block. Its mere existence breaks the world. Starting off as an average Wither, it goes OneWingedAngel, looking less like its original shape and more like something from Creator/HPLovecraft, sprouting CombatTentacles, growing to ten times its size and eventually becoming a distorted, black mass of destruction and death. It gets even worse in Episode 3, where it turns out to be an AsteroidsMonster.]]
* In ''VideoGame/{{MOTHER|1}}'', Giygas was just an alien. A very angry [[TheGreys Grey]] alien who tried being human for a while, but was upset when humanity took advantage of his knowledge and he was forced to try and stop it. In ''VideoGame/EarthBound'', Giygas has become something far more horrible. Mindless, he exists in the future and the past and has no physical form. [[{{Expy}} He's practically Azathoth with less tentacles]], and became the {{Trope Namer|s}} for one of the main characteristics of Eldritch Abominations, YouCannotGraspTheTrueForm.
* Vorgis in ''VideoGame/MugenSouls'' is enormous, roughly planet-sized and looks like a mix and match of various beasts thrown together with neon veins popping out. His entire existence is based around eating planets whole. He was once a very disobedient pet of a God of Destruction.
* The ''Mask of the Betrayer'' expansion pack for ''VideoGame/NeverwinterNights2'' 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.'''
* ''VideoGame/ParasiteEve''
** The title character. What you see at any given time is not so much a person with incredible power, but sentient mitochondria possessing a human host. In the game, Eve transforms into a half-human monster capable of hovering with no visible wings or legs, can set a person on fire by causing all of their mitochondria to go thermonuclear at once and can transform animals into monsters. The Ultimate Being is...worse. The best part? [[ParanoiaFuel Eve hints that this is what every mitochondria in every living thing wants to do,]] [[SealedEvilInACan being "liberated" from their host cell]].
** ''VideoGame/The3rdBirthday'' has its menace, known simply as the Twisted. Colossal tentacled monstrosities, the first thing we learn about them in [[http://www.youtube.com/watch?v=o_pTp-WZu3A&feature=sub the trailer]] is that they somehow ''erode '''time and space''''', and it seems the only way to stop them is by using TimeTravel BodySurf to SetRightWhatOnceWentWrong.
* ''VideoGame/{{Persona}}'':
** In ''VideoGame/{{Persona 2}}'', we have Philemon and the Lovecraftian deity Nyarlathotep. Both are similar in nature and origin, in that [[TheHeartless they came from humanity's collective unconscious]], with Philemon representing the "creative side" of humanity's mind, while Nyarlathotep represents its "destructive side". Naturally, the latter is the main villain. He also fits the trope straighter since Nyarlathotep can appear in physical world, and actually manages to [[spoiler:rewrite reality as we know it]] at the end of ''Innocent Sin''. His various forms, especially his Crawling Chaos form (this page's image), emphasizes just how different beings from the collective unconscious are when compared to the typical Personas or Shadows.
** ''VideoGame/{{Persona 3}}'' reveals a primordial goddess who existed long before humanity even existed, and actually helped to shape humanity's mind during the dawn of time by creating various Arcanas. She is referred to as The Mother, Death, and Nyx. All this time, Nyx hibernates [[spoiler:within the moon]], sleeping until humanity's mind become too clouded by self-destructive desires. If that happens, Nyx will be convinced that [[BlueAndOrangeMorality it's time for her to bring upon]] [[TheEndOfTheWorldAsWeKnowIt The Fall]] to end humanity. Naturally, she thinks that now is the time, and sends her avatar as the FinalBoss. [[spoiler:As the heroes fight her [[DoNotGoGentle to assert themselves as living beings]] (on the slimmest of chances they might even win), she then ''allows herself to be beaten'' as a courtesy to let the heroes live to their fullest, then [[TheBattleDidntCount shrugs off the defeat]] and continues to bring about The Fall]]. Ultimately, [[spoiler:this fate is only averted when the Main Character receives an EleventhHourSuperpower courtesy of ThePowerOfFriendship, and even that only manages to convince Nyx that it isn't the time to end humanity yet. Oh, and by doing so, the hero ''dies''. She then hibernates again, until humanity's collective unconscious calls her again]].
*** In the UpdatedRerelease, ''Persona 3 FES'', reveals another one. They learn the existence of Erebus, a being from the collective unconscious, representative of humanity's unconscious desire of death. This thing is the real problem of the story, not Nyx - Erebus' very existence causes Nyx to try and end humanity. [[spoiler:The hero dies not to seal Nyx away, but to keep Erebus from calling Nyx. However, Erebus is trying to fix that through the Abyss of Time, to rewind time, recall Nyx, and ensures humanity's end]].
** In ''VideoGame/{{Persona 4}}'', many things from beyond the TV screen count, as do [[spoiler:Izanami]], who is another representative of humanity's collective unconscious, specifically the willingness to lie and desire to run away from truth.\
*** The ''VideoGame/{{Persona 4 Arena}} series has [[spoiler: Hi-no-Kagutsuchi]], the collective will of those who abandon all connections, and strive to live only for themselves.
*** ''VideoGame/{{Persona 4 Dancing All Night}}'' has [[spoiler: Mikuratana-no-Kami]], the embodiment of the desire for an eternal, painless bond, even if said bond is false.
** ''VideoGame/{{Persona 5}}'' continues the trend with [[spoiler: Yaldabaoth]], the embodiment of the collective desire to maintain social order, regardless of the costs or actual morality of such actions.
* Dark [[SpellMyNameWithAnS Force/Falz]], perennial BigBad of the ''VideoGame/PhantasyStar'' series, definitely qualifies[[spoiler:, as does [[BiggerBad its master]], [[VideoGame/PhantasyStarIV the Profound Darkness]]]].
** The Darkers in ''VideoGame/PhantasyStarOnline2'' are an entire race of Eldritch Abominations that take on a variety of forms, including BigCreepyCrawlies, CreepyCrows, and [[MyLittlePanzer evil toys]].
* ''VideoGame/{{Pikmin}}''
** The Waterwraith boss from ''Pikmin 2''. Its mentioned as being anchored in another dimension and capable of causing fear to the point of insanity.
** ''Pikmin 3'' has [[spoiler:The Plasm Wraith, the game's final boss]] a sentient moving blob of golden goo with a strange cube in the center, that appears vaguely humanoid at times. It's based off the Umibozu of Japanese folklore, an equally eldritch monster that destroys ships and keeps the treasures and captains for itself, [[spoiler:a fate Olimar nearly suffers. You can't even kill it, as when you leave the planet in the ending, it's fully reformed at full power, roaring in anger as you blast off.]]
* The entire setting of ''VideoGame/Prey2006'', 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. It is implied that it seeded Earth with life just so it could come back and eat everyone. And they can, apparently, invade the spirit realm via portals, although even they are taken aback by the sudden spirit activity.
* ''VideoGame/{{Quake}}'' has Shrak, the final boss of the expansion pack.
* ''VideoGame/QuestFantasy'' has [[spoiler:S O U L, Snaily Joe and Shachihata.]]
* The Dark One from ''VideoGame/QuestForGloryIV'' is one of these and an obvious Cthulhu reference.
* In ''VideoGame/RatchetAndClankFutureACrackInTime'', you actually get a gun (the Rift Inducer 5000) that opens a portal to a cosmic horror that will eat your enemies. [[FluffyTheTerrible Its name is Fred]].
* The Bydo in ''VideoGame/RType''. As the instruction manual puts it, "A living weapon built with the [[TheVirus self-replicating properties of DNA]], the Bydo has physical mass, yet exhibits the properties of a wave. It [[HordeOfAlienLocusts diffuses easily]] and [[EvolutionaryLevels fills any environment it encounters]]. The Bydo can even [[MindScrew interfere with]], and ultimately [[BrainFood consume]], human thought itself." About the only effective weapon against the Bydo is [[HeWhoFightsMonsters themselves]]. Humanity is only standing its ground by using carefully [[SealedEvilInACan controled Bydo flesh]] in the form of the Force units. Whether they can ever have a true victory over an enemy that [[PlaceBeyondTime exists outside time]] is [[FightingAShadow another matter]]. They can also infect and corrupt both living things and machinery. How? AWizardDidIt -- no, really. They're canonically stated to have been created using both science ''and'' black magic.
* In ''Franchise/ResidentEvil'' 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 its famous viruses. Its also worth considering that the Plaga were fossilized when they were discovered. So while they were discovered hundreds of years ago, they could be thousands, millions or ''billions'' of years old.
** The [[TheVirus G-Virus]] is this in viral form. Or, rather, it creates Eldritch Abominations. The G-Virus causes rapid, random mutations whenever its host is "killed", gradually causing more radical changes to the point where the host is not even recognizable. By the time ''VideoGame/ResidentEvil2'' ends, G-Virus creator and victim William Birkin goes from a physically normal human being to a gigantic fleshy mass of tentacles, teeth and eyeballs that is only destroyed by a massive explosion.
* In ''VideoGame/ReturnToKrondor'', 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.
* While the six dragons in ''{{Rift}}'' are explicitly stated to be mere manifestations of the Elemental Lords, [[MakingASplash 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 legends of ''VideoGame/{{Ryzom}}'' mention a [[OurDragonsAreDifferent Dragon]] whose breath created [[TheCorruption the Goo]] and who sleeps in the Prime Roots after having been beaten back by the Karavan. The legends go on to say that when The Dragon wakes up again, it will bring about TheEndOfTheWorldAsWeKnowIt in its death throes, killing any Homins left on Atys. The Fyros want to [[DidYouJustPunchOutCthulhu kill it]], which irritates the Karavan to no end since their policy with the beast is "DO NOT TOUCH."
* The BigBad of ''VideoGame/SaGa3'' is [[spoiler:a blobby mass of goo and tentacles which can absorb the power of a PhysicalGod via BodyHorror. Plus creating an EldritchLocation outside of time and space. As the most powerful of the setting's divine creatures, it could easily be a stand-in for Azathoth.]]
* Yog-Shoggoth, AKA [[spoiler: Dr. Norrington]] from ''VideoGame/SamAndMaxTheDevilsPlayhouse'', is explicitly stated to be an Elder God, and is built up to be just as mind-breakingly horrifying as any other example on this page. [[spoiler:When we get to see him, it's a bit underwhelming. He's embedded in Paiperwaite's torso, and can do nothing but move his head and arms. Coupled with his gruff British accent and generally refined nature, it's not a very threatening sight. He boasts that his true form is much more terrifying, though.]]
** [[spoiler:Junior, the original "owner" of the Devil's Playbox, plays this trope completely straight appearance-wise, but his behavior more resembles a spoiled toddler than anything.]]
** [[spoiler:Maxthulu, the fused form of Max and Junior, is essentially a {{Kaiju}} version of Max with incredibly powerful psychic powers.]]
* ''VideoGame/SanityAikensArtifact'' has individuals given [[PsychicPowers psychic abilities]]. The psychic abilities, however, cause individuals to [[WithGreatPowerComesGreatInsanity become insane if they are overused]], and these abilities [[spoiler:were given through an artifact that was planted by a Sanity Devourer, who will harvest a planet once psychic abilities become commonplace enough for easy eating.]]
* ''VideoGame/SepterraCore''. 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 its three heads. That alone is comparable in size with other, rather huge summons. And it isn't known how large the rest of its body is. It's also rumored that it's an inteligent being and that if its heads ever all agree on something, it will cause TheEndOfTheWorldAsWeKnowit.
* ''VideoGame/ShadowHearts'' is filled with these things. The FinalBoss of the first game, Meta-God, [[spoiler:is a SufficientlyAdvancedAlien crossbred with a horse and is beyond human reasoning.]] ''Covenant'' sets up Amon, one of Yuri's strongest Fusions from the first game ([[spoiler:second to Seraphic Radiance]]), as part of a triumvirate of eldritch horrors, opposed and matched by Asmodeus and Astaroth.
* ''VideoGame/ShadowOfTheColossus'' features Dormin, which refers to itself in the plural, is able to resurrect the dead, was sealed inside the bodies of 16 giants (the colossi) and gradually begins to take over the body of Wander, giving him black veins and a pale almost dead complexion. When it takes over him entirely at the end to prevent Emon from killing Wander it turns him into a colossus wreathed in shadow and so massive that he can't move inside of the cathedral, even when practically lying down, allowing Emon to kill him with ease, but even without a host and seemingly nothing attaching it to the world anymore Dormin is still able to bring Wander back as a baby (albeit one with horns). Also the colossi are implied to have been made to seal it away are were made very damn hard to kill for the reason to keep it out of this universe.
* In the Video Game ''VideoGame/SpaceStation13'', there is a cult that can summon forth Nar-Sie, the god of blood, that explodes anybody who comes near him.
* In ''VideoGame/ShinMegamiTenseiStrangeJourney'', ''all'' demons [[YouCannotGraspTheTrueForm 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. [[spoiler:The FinalBoss of two routes, [[GaiasVengeance Mem]] [[MotherOfAThousandYoung Aleph]], also appears as an Unknown until [[TouchedByVorlons an outside force]] grants you the ability to see her.]]
** ''Every'' demon is technically this, even those that resemble humans. They're masses of energy given thought and shape by belief (whether it comes from humans or otherwise, even other demons, really doesn't matter), from the lowliest Slime, to the highest deities of every pantheon.
* The eponymous GeniusLoci of ''Franchise/SilentHill'' feeds off of people's emotions, magnifying and returning them. Originally it was a place of healing and safety, but centuries of death and suffering turned it savage, inflicting pain of its own in a positive feedback loop. Then the local ReligionOfEvil had the bright idea of focusing all that misery into [[PoweredByAForsakenChild one little girl]] in the hopes of birthing a "God" to turn the world into "[[EldritchLocation paradise]]". Long story short, the town became outright ''malevolent'', trapping people in a nightmare [[YourMindMakesItReal of their own creation]] to feed and become ever stronger, eventually spreading far beyond the borders of Silent Hill itself.
* ''VideoGame/SinAndPunishment'': 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 ''VideoGame/SinAndPunishmentStarSuccessor'', particularly his [[http://www.youtube.com/watch?v=5f32EB6bMSs final form.]]
* Much of the horror that occurs in the first ''VideoGame/{{Siren}}'' is the result of a village of people eating one alive out of desperation.
* ''VideoGame/{{Skullgirls}}'' has the Skullgirl itself, the result of an evil artifact known as the Skull Heart transforming women who use it to make ill-considered wishes[[note]]The Skull Heart will transform women [[JackassGenie no matter what they wish for]], [[ArtifactOfDoom because it considers wishes ill-considered by nature]][[/note]]. Marie, the current one, looks like an ordinary girl until she's greatly threatened - at which point she turns into a hideous creature made of assorted bones.
* ''Franchise/SonicTheHedgehog''
** Dark Gaia, a SealedEvilInACan Eggman released in ''Videogame/SonicUnleashed'', is a ''sentient force of nature'' who ''helped create the universe'' (by destroying the old one, but meh). [[spoiler:Since the "stars ''aren't'' right" this time around, though, it breaks up into various [[TheHeartless Heartless-esque]] critters and the BalanceBetweenGoodAndEvil causes his [[EvilCounterpart Good Counterpart]] to be released as well, and he helps Sonic seal Gaia up again.]]
** Chaos, from the ''VideoGame/SonicAdventure''. [[spoiler:However, it is usually benevolent, but was driven to evil by Pachacamac's MoralEventHorizon. It turns good again at the end of the game.]]
** There's also [[spoiler:the trio]] from ''VideoGame/SonicTheHedgehog2006'': Iblis, a massive beast of destruction made only out of fire; Mephiles, a gasseous-liquid mind of complete corruption and shadowy powers; and [[spoiler:Solaris, an ''interdimensional being trying to destroy reality'']].
** In ''VideoGame/SonicGenerations'', there's the Time Eater. While most of its presence in the game is [[spoiler:as a robotosized/cybernetic vehicle operated by Robotnik and Eggman]], Eggman reveals its natural purpose, when he discovered it, [[spoiler:is to erase time, making most of what the Eggmen have it do already a natural ability.]] Between that, its looks, and the dimension the game takes place in, as well as the location of the last boss fight...
* VideoGame/SoulSeries: Soul Edge started out as an ordinary sword, but became the avatar of Inferno, a soul-eating abomination that [[GrandTheftMe 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 [[EldritchLocation Astral Chaos]] and either repairs itself or scatters its shards around the world. And [[spoiler:[[DistaffCounterpart Soulcalibur]]]] [[LightIsNotGood isn't as different as many expect...]] In MassiveMultiplayerCrossover ''VideoGame/NamcoXCapcom'', the Soul Edge is the missing half of BigBad [[MultiversalConqueror 99]] and has power to cut ''anything''. Its mere presence accidently severs the link between [[spoiler:[[VideoGame/{{Darkstalkers}} Morrigan Aensland and Lilith]]]], which mean it can ''cut souls in half''.
* ''VideoGame/{{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 [[TheDragon Jado]], who refers to himself as "The Great Negative". Krux, the BigBad of the series, is a HumanoidAbomination.
* The "Corrupted" in ''VideoGame/{{Splatterhouse}}'' are described as arising from the difference between what people mean when they say something, and what other people understand it as meaning--specifically, they're embodiments of the pain and suffering that often results from such misinterpretations. As ephemeral beings, they can't exist in this world without a host body, which is for the better, since even an enhanced human [[BrownNote can't so much as look at them]]. (They're willing to make deals with humans, but it's indicated they have no intention of honoring them--maybe not even a ''concept'' of honor.)
* ''{{Starbound}}'' starts out with the destruction of planet Earth and the peacekeeping [[TheFederation Terrene Protectorate]] by the enormous, skyscraper-sized tentacles of The Ruin, an ancient force of destruction and chaos that has been sealed away in a failing extra-dimensional prison since times immemorial. The final plot mission of the game transports you to The Ruin's prison and onto the creature's surface... [[ThatsNoMoon and you're explicitly told]] that while it ''appears'' to be a planet, it is actually a [[WombLevel planet-sized living organism]].
* ''VideoGame/StarControl''
** [[ArtificialHumans 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. If you ask the Orz about the Androsynth, [[BerserkButton they attack and take no prisoners]]. It's not exactly clear ''what'' went down, but the [[TheGreys 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, because, early on, the Orz seem comical, with their round, bird-beaked bodies, their [[StarfishLanguage nearly-untranslatable speech]], and their silly voices. [[http://wiki.uqm.stack.nl/Orz According to developers]], Orz, as the captain sees them, are actually a *fingers* projection of some higher-dimensional being.
*** At one point, you can find them above what used to be the Taalo homeworld. 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'' [[http://www.youtube.com/watch?v=pz_k2l10YXA#t=55s screaming]]. It doesn't ever actually appear, which somehow [[NothingIsScarier just makes it worse.]]
** ''Star Control 3'' has the Eternal Ones; they're invincible and feed on "sentience", so they wait for advanced civilizations to develop and then come and harvest them.
* ''Franchise/StarCraft''
** The Zerg Overmind. 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 its purpose is to assimilate or exterminate everything, ''everywhere''.
** ''VideoGame/StarCraftII'' [[spoiler:makes it into a PapaWolf by revealing that soon after its creation, a... ''[[OmnicidalManiac Dark Voice]]'' corrupted it and imposed its millenia-old directive of exterminating the Xel'Naga and the Protoss (and presumably everything else). Since the Overmind was created without free will, it could only follow this directive while [[AndIMustScream raging inside its own mind]].]] Not that it ever cared for the [[spoiler: Protoss or Terrans]], mind you, it just didn't want [[spoiler: its own children, the Zerg, to become CannonFodder and nurishing food for the Dark Voice and his underlings in their galactic conquest.]] Hence it created a successor, and set its course straight for Auir, knowing it would likely be slain there - Leaving control of the Zerg in his replacement, who would hopefully [[spoiler: not be influenced by the directive.]] Seems like [[EvenEvilHasLovedOnes even Eldritch Abominations has loved ones]] that they're willing to [[spoiler:[[HeroicSacrifice sacrifice themselves for]]]].
** [[AlwaysABiggerFish And Amon is just the bitch of]] [[TheChessmaster The]] [[RealityWarper Voice In]] [[SealedEvilInACan The Darkness]] from Frontline. [[spoiler: Oh, and it survived the power of a Xel'Naga weapon that LITERALLY RIPPLED SPACE-TIME, so another Kerrigan Sacrifice won't work]]
** The Xel'Naga themselves. They are near immortal beings that come from the Void (or literally nowhere, a place between universes). They don't have any physical form until they enter a new universe, and when they gain a physical form, it looks like a [[{{StarfishAlien}} gigantic manatee with tentacles]] (well, at least in our universe).
* ''VideoGame/StarWarsTheOldRepublic'':
** Sel Makor [[spoiler:created the Voss species and grants them their visions]]. It is the living embodiment of their war with [[spoiler:the Gormak]] and grows stronger with every death.
** The World Razer, who the Rakata were so afraid off, they [[spoiler:built an entire planet to imprison it. You have the option of releasing it.]]
** The Sith Emperor gained immortality by absorbing all of the Force energy of a planet, to the point that the Force ceased to exist in its atmosphere, and plans to do the same [[spoiler:to the entire universe.]]
* ''Franchise/SuperMarioBros'':
** [[spoiler:The Shadow Queen]] in ''VideoGame/PaperMarioTheThousandYearDoor'', whose very presence is capable of plunging the world into an unholy darkness. Bonus points for being [[ThatOneBoss amazingly difficult to defeat]] and rather unsettling.
** ''VideoGame/MarioAndLuigiBowsersInsideStory'': The Dark Star's introduction sounds straight out of Lovecraft, and by the time it's [[SealedEvilInACan 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 [[{{Determinator}} Bowser]], who looks forward to the challenge.
* ''VideoGame/SuperRobotWars''
** [[VideoGame/SuperRobotWarsCompact2 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 ''Hagane no Messiah '' and claim to be the ones who created the world by creating the Crossgate dimensional portal and turning the world into several mini-dimensions separated by a dimensional wall. It turns out that Einst's goal is to return to the original world, "the world of silence". Their hive mind doesn't recognize individual will and express genuine confusion when humanity foil their plan.
** ''[[VideoGame/SuperRobotWarsDestiny Super Robot Wars D]]'' has Perfectio, king of the Ruina, EnergyBeings 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.
** ''VideoGame/SuperRobotWarsK'' has Lu Kobol, an evil being defeated by [[{{Precursors}} Crusians]] long ago. The Crusians even [[SealedEvilInACan hid Lu Kobol's fragments in planets across the galaxy]] to ensure it won't return easily. Yet Lu Kobol resurrects as EnergyBeings and seeks to reform itself by [[EarthShatteringKaboom destroying every planet that hides its fragments]].
** ''VideoGame/SuperRobotWarsZ'' 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. (A small note is that ''[[http://en.wikipedia.org/wiki/Taiji Taichi]]'' is from Taoism with some MindScrew-level properties.)
*** ''Super Robot Wars Z3: Hakai-hen'' reveals what exactly this is. The Supreme God Z, a large angelic being that has existed for countless cycles, is responsible for creating and ending the universe, and is so powerful that the ''corpse'' of its previous incarnation, Sol, has reality warping powers.
* ''VideoGame/SuperSmashBros 4'' has, [[SurpriseCreepy surprisingly]], the [[TrueFinalBoss Master Core]]. It's a chaotic entanglement of formless, sentient dark matter residing within Master Hand, that takes forms that can be vaguely likened to humans, scorpions, and swords (which themselves suffer disturbing amounts of BodyHorror) before [[MirrorMatch assuming the player's form]]. More shocking still, [[InterfaceScrew it blocks out its HP gauge with amorphous black masses]]. Finally, after being whittled down to its final form, it turns into an literal [[EldritchLocation fortress of dark matter]] before reverting to a form appearing similar to a Smash Ball (which is still capable of killing you).
* The Suul'ka of ''VideoGame/SwordOfTheStars'' are [[StarfishAliens Liir]] who've grown so old and so large that they cannot survive in gravity wells. Their psi abilities allow them to coerce fleets to join them, feed on the LifeForce of entire planets, and they can "teach" their vast and ancient knowledge to their followers. But their minds are so vast and complex that many Zuul who are taught by telepathic contact die, until eventually one feebly mumbles "Eureka... please, Lord, stop..." From the Liir perspective, they're closer to {{Humanoid Abomination}}s.
* Yuris from ''VideoGame/TalesOfRebirth''. It's [[TheHeartless the physical manifestation of all of the negative emotions]] produced by the Huma and Gajuma after they're subjected to a HatePlague and has a rather indescribable appearance.
* ''VideoGame/TalesOfVesperia'' has the Adephagos, [[spoiler:which is a SealedEvilInACan abomination and is released about 2/3rds into the game. It's destroyed by stopping using aer as an energy source and switching to using mana instead.]] A cookie to those who get the [[GreenAesop aesop]].
* ''VideoGame/{{Terraria}}'' has the [[AdvancingBossOfDoom Wall of Flesh]]: an enormous [[MeaningfulName 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. You can't escape without killing it, but killing him supercharges TheCorruption throughout the world, causing it to spread aggressively past nearly all barriers... and introduces a ''second'', opposing style of corruption which spreads equally quickly. And it makes more deadly enemies appear everywhere.
* ''VideoGame/TheLastDoor'' heavily features a yet-to-be-explained god-thing referred to as the Bird/King of Birds. The protagonist Jeremiah, two friends, and a priest at their boarding school attempted to look beyond the veil of human perception through some sort of ritual or incantation. Though the game is very vague (as of now, anyway) on what exactly happened, it's clear that they somehow contacted the Bird and it drove them all insane in different ways. As Jeremiah explores the spooky settings of 1890s Scotland and England, the Bird appears in nightmares, windows, and keyholes as a giant orange/yellow eye that screeches and then disappears.
* ''VideoGame/{{Touhou}}'' gives us the Saigyou Ayakashi, a demonic entity taking the form of a cherry tree. It drew people to its side with its beauty, tempting them to sleep under its branches... at which point it devoured their souls. Out of all of the characters in the series, it's one of the miniscule handful that can actually be called evil. Currently it's SealedEvilInACan, the body of a powerful young woman being buried beneath its roots to render it comatose; ''Perfect Cherry Blossom'' revolves around keeping Yuyuko from unknowingly breaking that seal by bringing the woman back to life (thanks to GhostAmnesia, [[spoiler:she's forgotten that she ''is'' that seal]]).
* The ''VideoGame/{{Turok}}'' series has the Primagen, a SealedEvilInACan from the dawn of time who threatens to break out of his prison and [[EarthShatteringKaboom unravel the fabric of the universe]]. Acting as the BiggerBad to Primagen is Oblivion, an even more ancient Lovecraftian PlanetEater who becomes the third game's BigBad.
* The Myrmecols from the ''VideoGame/UFOAfterblank'' 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.
* ''VideoGame/{{Undertale}}'':
** [[spoiler:Flowey, after absorbing the souls of Asgore and the six fallen children. In a world where battle sprites are monochrome and pixelated, he appears as a multicolored, photorealistic meld of flesh, plant and machine, capable of generating bunker buster bombs and finger guns en masse with a thought. Oh, and he weaponizes SaveScumming.]]
** [[spoiler:Dr. W. D. Gaster, who was deliberately [[RetGone removed from the game]] but left in the files. In-universe, simply knowing him too well caused others to forget about him completely, or worse, to be removed from existence just as he was. The worst part is that he [[AndIMustScream is aware that the universe went on fine without him.]] [[MindScrew He exists, but he also doesn't.]]]]
** [[spoiler:And especially the Amalgamates, which are actually nothing more than normal monsters from the game...but fused and melted together into horrifyingly grotesque and disturbing new forms as a result of Alphys' tragically failed Determination experiment to try and find a way to get monster souls to persist after a monster's death, in hopes of gathering enough of those to break the barrier with instead of waiting for more humans to fall down. Literally the only thing uglier than their appearances is their origins.]]
** The only being more disturbing than any other in Undertale is [[spoiler:Chara, the adopted child of the Dreemurrs - or whatever is claiming to be Chara. You only get to meet them at the end of a [[KillEmAll Genocide]] playthrough - after many implications that they are [[TheNarrator the game's narrator]] - when they praise you and offer to destroy the entire game world. Appropriately enough, they make an ominous declaration that they would [[TheFourthWallWillNotProtectYou "move on to the next [world]"]] once they had done so. [[SadisticChoice Regardless of whether or not you become their partner]] they do just that, and restoring the game to a playable state without editing the game files [[HappyEndingOverride permanently taints every future playthrough.]]]]
** Recently, along with the theory that [[spoiler:Chara is the narrator of all routes and is only corrupted by the player in a Genocide Run]], another character has become a strong contender. It's [[spoiler:YOU, the player]]. A being [[BlueAndOrangeMorality beyond comprehension in the eyes of the other characters]], the same species as the creator of the world, [[KarmaHoudini utterly beyond punishment]] and [[RealityWarper capable of altering reality with ease]]. Powers include [[DemonicPossession possessing children]], [[RetCon returning lost beings back into existence]], resetting the world, SaveScumming and, yes, [[ScrewDestiny even undoing what cannot be undone]]. No one can understand why such a being would do what it does.[[note]]Only [[spoiler:Sans and Chara in a Genocide Run seem to come close to understand the motivations of someone who would slaughter everyone just to have a HundredPercentCompletion]].[[/note]] The only one who seems to be aware that [[spoiler:you're a human from outside their world is Chara, who at the end of a Genocide Route states that the "human SOUL" and "determination" were yours]].
* PlayedForLaughs in Japanese ''VideoGame/SuperMarioWorld'' GameMod ''VIP MIX 2''. The final boss is supposedly the creator of the game himself, who appears as a cluster of 2ch memes. In ''VIP 5'', [[spoiler:the 2ch meme Tanasinn is the TrueFinalBoss.]]
* ''VideoGame/{{Warcraft}}''
** ''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 [[DidYouJustPunchOutCthulhu easy to kill]], though.
** ''Warcraft'' also features the Old Gods (of which the Faceless are servants), which are {{Shout Out}}s to Lovecraftian entities. (Although [[SerialNumbersFiledOff they may shout a little too loud]] here.) 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, the mantid and the nerubians. They're also the (partial) creators of Humans, some Giants, Dwarves, Gnomes, and Troggs by using 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 faced him at 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, [[LoadBearingBoss they take Azeroth down with them]]. There is also the question of whether they can even be truly killed. They are said to exist "outside the cycle" of life and death. Though C'thun is technically dead, it was still able to mutate and transform Cho'Gall into a monstrosity.
** The Faceless return in ''WorldOfWarcraft: 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, and all sorts of other weirdness in Northrend, seems to be an Old God named Yogg-Saron (not to be confused with Yog-Sothoth). Just Yogg-Saron's existence beneath the lands drove creatures to madness and its very ''blood'' is forged into equipment for arming the armies of undead in Northrend (being mindless helps protect against losing ones mind).
*** 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 [[DidYouJustPunchOutCthulhu 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 [[spoiler:the corruption of Deathwing was so extensive that after tearing off his elementium plates, he transforms into something very like an Old God, complete with a spell that can destroy the entire world]]. That spell doesn't just kill the raid. It turns the screen completely black, even the chat-box. The only thing visible is the release soul button.
** ''Mists of Pandaria'' has the Sha, seven black creatures that embody doubt, hatred, fear, violence, anger, despair, and [[spoiler:pride]]. [[spoiler:It is implied that they are the remains of a dead Old God, the seven-headed Y'shaarj who was killed by the Titans long ago.]]
* ''Franchise/WildArms''
** Ragu O Ragula, a monster of practically unimaginable destructive power, appears in every ''Wild [=ARMs=]'' game. Almost always a SuperBoss 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 ''VideoGame/WildArms2'', [[spoiler:the PlanetEater "Encroaching Parallel Universe" Kuiper Belt does this trope in a decisively terrifying way, complete with music that perfectly captures "too terrible to exist in my universe".]]
* ''WoodruffAndTheSchnibbleOfAzimuth'': [[spoiler:The Beast, an ancient Bazouk devil-figure.]]
* In ''VideoGame/{{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 ''VideoGame/{{Xenosaga}}'', it is believed that GodIsEvil and one of these... [[spoiler:but then it turns out that God is actually benevolent. It's just that His ''actual'' form drives them mad.]]
* Galvaran, Jabir, Napishtim, etc. in the ''VideoGame/{{Ys}}'' series. Many of these monsters were created when the humans who stole the [[ArtifactOfDoom Black Key]] attempted to recreate [[{{Unobtainium}} White and Black Emelas]], but after failing that, infused the resulting Ash Emelas into soldiers.
* ''Isle of Rebirth'', a custom quest in ''VideoGame/ZeldaClassic'', features two:
** One BonusBoss, Tartaros, is described in-game as something so evil that its mere presence in the physical world blights the land, and it took an entire city of fairies just to seal it away. Link finds it in a "cocoon" resembling the Wind Fish's egg, but covered in veins and bloody eyes. It ''can'' be [[DidYouJustPunchOutCthulhu defeated]], but it's widely recognized as the most difficult boss ever scripted for Zelda Classic.
** The BigBad, [[spoiler:Venser]], also qualifies. [[spoiler:He's a dead "false god" from another dimension who's trying to collect the Triforce to be reborn and return home. Unfortunately for everyone else, the latter involves recklessly tearing through other dimensions - including Hyrule's - and causing them to collapse. His true form wouldn't be out of place in a Lovecraftian setting.]]
* The ''[[NexusWar Nexus Clash]]'' pantheon has Ahg-Za-Haru, an unknowable, mindless singularity of pure hedonistic [[ItsAllAboutMe selfishness]] and Tholaghru, a world-sized, slavering and utterly insane chaotic god-being responsible for most of the setting's BodyHorror. Tlacolotl, the third evil member of the pantheon, is [[HumansAreBastards all too human]].
* The Hours in ''[[http://weatherfactory.biz/cs/main_ui.html Cultist Simulator]]''. There are thirty of them, although so far only a handful have names - most notably [[HorrorHunger the Red Grail]] - and they dwell in the Mansus, also known as "the House in the Woods", grey and gold, which is patrolled by the Watchman and his Lantern. The objective of the current prototype is to balance resource needs and item crafting to carry out a ritual to summon a "Thirstly" of the Grail into the city's dreams, causing them to rise from their beds and presumably start killing; in the full version, there will presumably be other options. Learning about the Hours tends to be bad for your SanityMeter.
