[[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...]] It has a human Avatar controlled by the [[spoiler:Dark Presence]] which is implied to be the avatar of an even ''worse'' thing.
* In ''VideoGame/AmnesiaTheDarkDescent'', you are being followed by these "things" or "shadows" as you explore the castle. You have no weapons/defense other than hiding either, so there is a sense of hopelessness. While their appearance is a blurry/melted shambling humanoid, staring at them for more than a few seconds will cause you to lose sanity (an in game statistic). [[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 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.
* Gohma Vlitra and [[spoiler:Chakravartin]] from ''AsurasWrath'' are relatively hard to comprehend, especially when the latter [[spoiler: 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]] themselves count, specially Iustitia, one of the cardinal virtues, intentionally designed like a mixture of a carnivorous plant with a tentacle monster with creepy cherubic baby faces everywhere because of its moral ambivalence.
* 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 abomiantion]].]]
* ''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]].
* ''VideoGame/{{Borderlands}}'' has [[spoiler:the thing that was inside the Vault.]]
* ''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.
** And then there is the recurring boss Legion/Granfalloon, a tentacled... thing... that surrounds itself with an enormous ball of human corpses fused together. When damaged, the corpses wail and sometimes animate as zombies.
** Cthulhu himself is actually an enemy in some of the games. A minor, recurring enemy.
*** How Cthulhu came to be in ''Castlevania'' is a highly confusing tale of shoddy translation. There were two similar enemies in ''Symphony of the Night'', known in Japan as "Devil" and "Evil." Devil was a traditional-looking demon, while Evil resembled Cthulhu. For reasons unknown, it was Devil's name who was translated as "Cthulhu," while the one who ''actually'' looked like Cthulhu was dubbed "Malachi." Both enemies have reappeared in later games, but while "Cthulhu" reverted to the more proper Devil name, Malachi has consistently stayed Malachi... despite resembling Cthulhu. Whew!
* ''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. 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. It's 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. [[spoiler:Originally, humanity used the sun as a source of magical power, but the sages of the great magical kingdom of antiquity tapped into Lavos, and apparently, he beat the sun's magic, managing to power a floating continent of mages even before they managed to directly tap into its power. The main characters end up using sun-granted magic to defeat him, so there]].
* 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 several:
** 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.
* The ''VideoGame/DarkSouls'' content in the [[UpdatedRerelease Prepare to Die]] edition introduces [[spoiler:Manus, Father of the Abyss, who is heavily implied to be the Dark Soul's wielder, the Furtive Pygmy]]. With this revelation, it might not be too inaccurate to say that anyone who has [[spoiler:a Lord Soul]] has a good chance at becoming one of these.
* "VideoGame/DarkSoulsII" has quite a few. from The Rotten, a massive pile of corpses given life that appeared in the trailers, to the [[spoiler: Darklurker, an insanely powerful... creature... living in what became of the abyss between the game and it's prequel]]
* ''VideoGame/DawnOfWar'' (naturally, given [[TabletopGame/{{Warhammer40000}} the source material]]) has the unnamed Daemon of Khorne, and Ulkair. 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 latter's defeat only sealed him back into the planet, while the former is ''never'' fought directly, only the [[OneWingedAngel Daemon Princes]] it creates by imbuing loyal followers with its power.
* ''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]].
* The Old One from ''VideoGame/DemonsSouls''.
* Many of Franchise/CthulhuMythos' deities appear in ''VisualNovel/{{Demonbane}}''. Although the Great Old Ones are treated as just powerful monsters, the Outer Gods still play it straight. Unlike in the mythos, most Outer Gods are sealed in compact universes inside the Shining Trapezohedron. But Azathoth still generate countless universes from inside, making it the center of the multiverse (and the destruction of the Shining Trapezohedron will doom everything, for Azathoth will turn the whole multiuniverse into an EldritchLocation once it's free). At least two Outer Gods are free, for neither of them can be sealed. One is Yog-Sothoth (being the embodiment of all time and space) and the other is Nyarlathotep (being the will of the Outer Gods, and since the multiverses come from the thoughts of Azathoth, [[spoiler:sealing Nyarlathotep will simply drive it from your universe for a while, then it will re-emerge with another mask in an alternate universe]]). One of its forms, Clockwork Phantom, is an elaborate version of the Tik-Tok Man in the mythos, being a [[MechanicalLifeforms mechanic abomination]] that assimilated whole universes into itself.
* ''VideoGame/DevilSurvivor2'': The Septentriones. Considering they're [[WholePlotReference likely inspired]] by ''Anime/NeonGenesisEvangelion'', not really surprising.
* ''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.
* 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'' has several, the most noticeable being House Dagoth in ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'', but for the true position, Sithis takes the cake. Later games attempted to pass him off as a more traditional god of death, but the game's backstory reveals that he is actually a great void, the undying soul of a dead primordial force. [[MindScrew Sithis Is Not.]]
** The Daedric Princes appear to be at least heavily influenced by this concept. They 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.]] (One of them, Hermaeus Mora, doesn't bother with this and resembles a more typical abomination.) 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 ''[[VideoGame/TheElderScrollsVSkyrim 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.
** Also in Skyrim, Alduin. 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". Oh and 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.
* 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]]. 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.
* ''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).]]
* 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... 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.
* ''VisualNovel/FateHollowAtaraxia'' has Avenger, who's described as being an empty space in reality. The form you see is where "NOTHING" is.
* 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''
** 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 from 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]]''.
** 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/{{FinalFantasyXIII-2}} 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.
* In ''VideoGame/FinalFantasyTactics'', practically every major enemy in the game transforms into one of these at some point in the game.
* ''VideoGame/FinalFantasyTacticsA2'' has [[spoiler:the Neukhia, whose presence is so dangerously poweful, even having a LIMB in Ivalice presents an apocalyptic threat]]
* ''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 ''FreeSpace 2'' 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/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, 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 the Gravemind calmly pointing out the second time it is being destroyed 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 Flood combat forms. If this body is destroyed, it can rebuild itself if but one Flood Spore survives. It doesn't even have to be from that hive specifically. Any Flood under its control will do. And if that nigh invincibility isn't enough, the Gravemind also has telepathic abilities which it can project across ''interstellar'' distances. Factor in its love of trochaic [[ArcNumber heptameter]] and morbid metaphors and you have one creepy abomination.
** The Prisoner from the Cryptum novel. Described as a [[spoiler:huge, misshapen humanoid with four arms and compound eyes on an indescribably ugly face. And to top it all off, its kind created the Flood.]] The sequel reveals [[spoiler:the Prisoner to have lied: ''[[WhamEpisode it was a Gravemind]]''.]]
** Literature/TheForerunnerSaga delves even further to reveal the Floods origins, [[spoiler: the Flood are in fact the Percursors themselves, who have mutated themselves into the Flood so they can have their revenge on the Forerunners, and all of their creations.]] ''Literature/HaloSilentium'' proves 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 to even the metaphysical memory-bank called the Domain.]] 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, and [[spoiler: they're ''pissed'' at their creations for wiping them out.]]
* Would you believe that ''VisualNovel/HatofulBoyfriend'' has one? The sequel, ''Holiday Star'', has [[spoiler:The King, once an unstable and betrayed button quail named Nanaki Kazuaki, now a monstrous HiveMind that sprouts multicolored extra heads when angry, kidnaps our heroine and her birdy beaus to his FisherKingdom, and tries to absorb any souls he encounters, living or dead, out of desire for friendship without betrayal.]]
** The first game also had that JRPG boss at the end of Anghel's route, brought on by his RealityWarper hallucination powers. It looks like [[http://24.media.tumblr.com/tumblr_m8ic9uMOc81rs9wjoo1_500.png half of a bird fused to a tree made of exposed bloody flesh, with one feathered wing and one batlike wing and glowing eyes]].
* The Serpent Riders from the ''{{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/{{Homeworld}}: Cataclysm''. 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.
* ''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.
* ''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.
* ''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).
* ''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.
** 0 is the "heart" of Dark Matter, essentially a giant bloody eyeball in a white sphere. It returned as 02 in ''VideoGame/{{Kirby 64|TheCrystalShards}}'' with creepy wings and a halo. It's bizarre for an otherwise cutesy series.
** 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]].
** 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.
** Marx. He spontaneously grows plants made entirely out of spikes, can generate knives from nowhere, and can rip himself in half to create a hole to a dimension made entirely out of '''pain'''.
* ''VideoGame/KnightsOfTheOldRepublic II''
** [[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, and Vel'koz are all extradimensional horrors from the [[EldritchLocation Void]], which is ''crawling'' with them, while Kassadin and Malzahar are humans who take 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.
* [[BigBad Bacterion]], [[TheDragon Dr. Venom]], [[DragonAscendant Gofer]], and [[PlanetEater Zelos]], from ''VideoGame/{{Gradius}}'' are all Eldritch Abominations with the ability of regeneration and cell division. Dr. Venom wasn't always like this though.
* 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.
** Vaati became one after he went OneWingedAngel.
** 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 ''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 ''LittleBigPlanet 2'' to make an Eldritch Abomination out of a ''vaccum cleaner''! The Negativitron travels the cosmos, constantly sucking up all material in Craftworld. It can also be considered [[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 ''{{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 ''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.
* ''[[VideoGame/MarioAndLuigiBowsersInsideStory Mario & Luigi: Bowser's Inside Story]]'': 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.
** And a few years earlier and on a different system, we had [[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 insanely difficult to defeat]] and rather unsettling.
* ''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]]:''' [[foldercontrol]]

[[folder: 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.]]
* ''Franchise/{{Metroid}}''
** ''VideoGame/MetroidPrime'' has the sentient planet Phaaze. Among other things, it is inadvertently responsible for introducing the {{Starfish Alien|s}} like Ing to normal space.
** Phantoon. It's a ghostly... thing that inhabits abandoned ships. Its primary projectiles are eyeballs made of blue fire and it can turn invisible and intangible and open dark rifts and summon flying disembodied hands with [[EyesDoNotBelongThere eyes in their palms.]] It itself resembles a sea creature of some sort (with CombatTentacles, naturally) with a gaping toothy maw... which houses an eye. And no apparent throat. This creature just makes no ''sense''. ''VideoGame/MetroidOtherM'' concept art shows that Phantoon has a humanoid-shaped body to go along with that tentacled head and disembodied hands. The reason the head and hands are disembodied, though, is because he pulls the common EldritchAbomination trick of having most of his body existing in dimensions the human senses aren't built to handle.
* ''VideoGame/{{MOTHER}}''
** 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 the fan midquel ''[[VideoGame/CognitiveDissonance MOTHER: Cognitive Dissonance]]'', Giygas has gone completely insane due to the prediction of Ness defeating him and you can see his alien form being stretched and distorted.
** 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 TropeNamer 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}}''
** ''VideoGame/{{Persona 3}}'' has Nyx, an AnthropomorphicPersonification of Death, as its BigBad. It even subverts the traditional DidYouJustPunchOutCthulhu ending for video games featuring them: being Death itself, it can never be vanquished. SEES fights it [[DoNotGoGentle to assert themselves as living beings]] (and on the slimmest of chances they might even win). It allows itself 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 TheEndOfTheWorldAsWeKnowIt. Ultimately, this fate is only averted when [[spoiler: the Main Character receives an EleventhHourSuperpower courtesy of ThePowerOfFriendship, and he only manages to [[SealedEvilInACan seal it away]]]]. For an extra dash of terror, the body that SEES tried and failed to defeat was only Nyx's Avatar. [[spoiler:Nyx's true body is the moon, [[ThatsNoMoon and that surface is just a shell]].]]
** In the new chapter in ''Persona 3: FES'', the team discovers Erebus (Nyx's husband and brother in Greek myth). Aigis and company learn that [[spoiler:their grief over the hero's death]] not only manifested the Abyss of Time, but also helped fuel Erebus, the AnthropomorphicPersonification of nihilism and sorrow in human hearts. This "nihilism avatar" was the real problem, not Nyx -- Nyx existed long before humanity ever awoke and, by itself, wasn't a force of good or evil -- it was only when the self-destructive thoughts in Humanity hit a critical threshold that they coalesced into the decidedly unfriendly Erebus, who seeks to absorb Nyx's power and bring about TheEndOfTheWorldAsWeKnowIt. [[spoiler:The hero wasn't sealing Nyx away, but instead keeping Erebus away from Nyx.]] The party fights Erebus in a final battle and learns that [[spoiler:the protagonist can never return to them, because [[AsLongAsThereIsEvil so long as there is the desire for destruction in human hearts, Erebus will live on]]. However, a stated goal of the presumably immortal RobotGirl Aigis is to work to improve humanity to the point that Erebus ''can'' be defeated -- someday]].
** In ''VideoGame/{{Persona 4}}'', many a thing from beyond the TV screen, [[spoiler:as well as FinalBoss Izanami]], with a small caveat: [[spoiler:Izanami [[DarkIsNotEvil isn't really bad when you get to know her]]-- she happily accepts that it was just a big misunderstanding after you [[DefeatMeansFriendship prove the worth of humanity's bonds to her]].]]
** Lovecraftian deity Nyarlathotep is the villain in ''VideoGame/{{Persona 2}}''. However, he becomes ''far'' scarier than the run-of-the-mill EldritchAbomination by the single reason of not adhering to BlueAndOrangeMorality; due to his origins as [[spoiler:[[TheHeartless Humanity's destructive impulses in the Collective Unconscious]]]], meaning he ''knows'' he's a monster and ''revels'' in it. Unfortunately, among the many avatars it chose to screw with the heroes, [[AdolfHitler its most prominent one]] meant [[BadExportForYou half the game]] [[NoExportForYou was not released outside Japan]] until 2011's [[UpdatedRerelease PSP remake]]... wherein he was given sunglasses to at least mask his appearance a little.
*** ''Persona 2: Eternal Punishment'' included Great Old One Hastur, the Byakhees, and Elder God Nodens as summonable Personae, as well as Yog-Sothoth as a boss in the EX dungeon.
* Dark [[SpellMyNameWithAnS Force/Falz]], perennial BigBad of the ''VideoGame/PhantasyStar'' series, definitely qualifies[[spoiler:, as does [[BiggerBad its master]], [[VideoGame/PhantasyStarIV the Profound Darkness]]]].
* ''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.]]
* ''Franchise/{{Pokemon}}'':
** [[TheMissingno Missingno.]] and its [[http://bulbapedia.bulbagarden.net/wiki/Glitch_Pokemon glitchy ilk]] fracture reality by their very presence (music, graphics, and save data are twisted), possess bizarre dimensions ('M is 23 feet tall, and Missingno. itself is ''more than three thousand pounds''), and if exposed long enough, the protagonist's mind shatters entirely (the game crashes). As essentially junk data given form, to the player character they might as well be PrimordialChaos.
*** [[http://bulbapedia.bulbagarden.net/wiki/Female_symbol The glitch Pokemon]] whose name is only represented as a female symbol gets a special mention. It has an endless cry that actually sounds like a bizarre twisted song, it's base stats are second only to [[CrystalDragonJesus Arceus]], it looks like [[VideoGame/EarthBound Giygas]], and finally, it ''weighs 3 tons and is 80 feet tall''.
** Arceus itself, who despite being widely thought as the ''Pokemon'' equivalent of God (who has [[EldritchAbomination/MythologyAndReligion His own extensive entry]]) is actually closer to [[Franchise/CthulhuMythos Azathoth]], considering it created the universe largely by accident then went to sleep for a few billion years.
** Dialga and Palkia, Arceus first creations, are Space and Time personified (indeed Time started flowing with Dialga's creation) and their dominion over them is absolute. Their battle in the tenth film had so much power being thrown around that each of their attacks were damaging reality.
** Giratina is able to completely counteract both Dialga and Palkia, lives in [[http://bulbapedia.bulbagarden.net/wiki/Torn_World the Torn World]], a dimension [[EldritchLocation where time and space do not work like they should]], and can travel to different universes and warp reality. There's ''a good reason'' why people compare it to Yog-Sothoth.
** And then there are the Unown. While they're a JokeCharacter individually, they're a powerful reality-warping HiveMind in groups of hundreds. They come from their own dimension, live in inexplicable ancient ruins, and make incredibly creepy radio transmissions to boot. Oh, and Arceus uses them to make a new Dialga, Palkia, or Giratina in ''[[VideoGame/PokemonGoldAndSilver HeartGold/Soulsilver]]''.
** In the ''Jirachi Wish Maker'' movie, the villain Butler attempts to create a Groudon using Jirachi's wish granting powers. The result is a bizarre demon that ''looks'' like Groudon, but it's pretty easy to tell it's ''not''.
** To a lesser extent, Groudon, Kyogre, and Rayquaza. Ancient, slumbering entities responsible for the enviroment, they're millions of years old and, when awoken (well, not Rayquaza), start to cause the end of the world. Expies of the Behemoth, Leviathan, and Ziz, who are cosmic horrors on their own, they may very well be Pokemon [[Franchise/CthulhuMythos Great Old Ones to the Creation Trio's Outer Gods.]]
** The Bad Egg, [[DangerousForbiddenTechnique which you can get]] [[NoFairCheating by cheating.]] [[TheVirus They can turn other Pokemon into Bad Eggs.]] They're actually ''playable.'' And when they hatch... all you see is an egg, and then the game freezes. [[YouCannotGraspTheTrueForm Did the player]] GoMadFromTheRevelation?!
** ''VideoGame/PokemonMysteryDungeonGatesToInfinity'' provides one of the straightest examples of this in the franchise in the form of [[spoiler: the Bittercold, a non-sentient crystalline entity that embodies the negative feelings of all the Pokemon in the world and feeds upon said feelings to strengthen itself (Which is a bit of a problem considering [[CrapsaccharineWorld the game's setting]]). Pokemon suffocate simply from being near it and it ends up growing powerful enough to threaten the world's very existence.]]
* ''VideoGame/{{Prototype}}''
** The Blacklight Virus. A sentient virus that [[ImAHumanitarian consumes biomass]], can shapeshift, absorbs peoples' memories, singlehandedly demolishes entire armies, and is NighInvulnerable ([[spoiler:even a ''nuke'' couldn't kill it in the end]]). Even ''other'' viral monsters [[FoodChainOfEvil end up on its menu in the end]]. [[spoiler:And it's the ''[[VillainProtagonist protagonist]]''.]]
** [[spoiler:Elizabeth Greene,]] a HumanoidAbomination who looks like a normal, good-looking woman, but is [[spoiler:the Blacklight Virus's beta version]].
** ''And'' there's also [[spoiler:PARIAH. He's only mentioned, but it's implied that if he and Alex Mercer ever meet, it's TheEndOfTheWorldAsWeKnowIt.]]
** In ''Videogame/{{Prototype2}}'', the Blacklight Virus now has a new host: James Heller. And his powers are far more monstrous than Alex Mercer's in the first Prototype, thanks to his "tendrils" power. Whenever tendrils are involved, the result is masses of flesh dangling from the buildings with strung-up corpses caught like flies in spider silk.
* The entire setting of ''Videogame/{{Prey}}'', albeit being techno-organic alien in nature. Big enough to host every level save for the introduction and ending and never seen in its entirety. Reality-violatingly ugly as in portals, spatial anomalies, and multi-directional gravity. Happens upon the Earth on one night without any warning. 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 ''RatchetAndClankFutureACrackInTime'', you actually get a gun that opens a portal to a cosmic horror that will eat your enemies. [[FluffyTheTerrible Its name is Fred]].
* The Bydo in ''VideoGame/{{R-Type}}''. 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.
* In ''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...
* ''VideoGame/RuneScape'' has The Inadequacy and other monsters fought during "Dream Mentor", all of which are embodiments of Cyrisus' negative emotions.
** RuneScape also has the Chaos Elemental, and extremely powerful and alien looking boss monster that uses several weird attacks such as teleporting the player to confuse them or making their armor come off. It also gives cryptic clues about future game updates through the FourthWallMailSlot. The Chaos Elemental's GoodCounterpart, the balance elemental, is possibly even more [[MindScrew mind screwy]], because although it looks much less weird, when you fight it, it will suddenly stop fighting to speak to you as though you were a close friend who had already died.
** The Spirit Beast is a monstrous ghostly thing that lives in a parallel spirit dimension where it feeds off the souls of ghosts who became trapped there (inflicting AndIMustScream on them). It was trying to break between dimensions into the world of the living so it would have more souls to feed off of. The player is completely unable to directly attack it. It is defeated only by the player weakening it through indirect methods and then empowering the ghosts it was feeding off to be strong enough to finish it. Unfortunately, because of the properties of the parallel spirit world it was killed in, it death resulted in the manifestation of a Corporeal Beast in the real world. Luckily, the Corporeal Beast can be harmed by normal attacks, so this is better than if the Spirit Beast had escaped, but it still is one of the most dangerous monsters in the whole game.
** Tolna was a boy who was imprisoned and [[MindRape mind raped]] by an unknown force [[AndIMustScream for several years]] until he turned into a horrific three headed [[RealityWarper reality warping]] abomination who manifests bizarre Mooks based on his emotions, [[UnstoppableRage Anger]], [[NightmareFuel Fear]], [[MindScrew Confusion]], and [[DespairEventHorizon Despair]].
** Muspahs are bizarre monsters manifested from the dreams of a comatose and [[GooGooGodLike unintelligent]] elder god. They are what the Mahjarrat, a race of HumanoidAbominations created by the same elder god, have nightmares about. Said elder god, known as Mother Mah also created Seren (Ironically, one of the nicest of the [[JerkassGods gods]]) and Zaros (The most alien of the gods, who when on to create abominations of his own, known as the [[MixAndMatchCritters Nihils.]]). The world she rules over is a DeathWorld.
** The Pests are invaders from another dimension that all have extremely weird apearences, varrying from floating jellyfish to faceless elephants, to the queen which looks like a nightmarish slug thing.
** Agoroth, Mother Mallum, and the Sea Troll Queen (Which does not look like a Sea Troll at all) are worth mentioning. They are all sea monsters that likely were inspired by Lovecraft.
** The Stalkers are a race of eldritch horrors. They all have unnaturally huge eyes and weird attacks, and [[BrownNote their language is said to be harmful to humans that hear it]]. The strongest of them is known as [[NamesToRunAwayFromReallyFast World-gorger Shukarhazh.]]
** The inhabitants of the Abyss and the Infernal planes. The ones that players most commonly encounter look like [[BigRedDevil typical demons]] but the rest are far more alien. The Abyss itself [[HyperspaceIsAScaryPlace (which is the dimension that allow teleporting to work)]] may be one, because it looks like the insides of some huge fleshy monster full of [[BodyHorror teratomas.]]
* 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.]]
* In ''VideoGame/SamAndMaxTheDevilsPlayhouse'', Yog-Sototh, who looks suspiciously like Cthulhu and has many of the attributes of a cosmic horror, makes several appearences throughout the season. In episode 304, [[spoiler: he is actually seen. Then there's Junior, who is even more fearsome, and Maxthulhu, when Max's psychic powers combine with Junior's Taint]].
* ''Sanity: Aiken's Artifact'' 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.]]
* ''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.
* Not only is ''VisualNovel/ShikkokuNoSharnoth'' full of these in the form of the <>, but [[spoiler:M, the protagonist's cryptic guide, benefactor, and possible love interest, is later revealed to be Nyarlathotep]].
* 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]].
* 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 it's 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. 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.)
* ''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]]]].
* ''VideoGame/SuperSmashBros for Nintendo 3DS''. Two words: Master Core. Its appearance consists of a mass of dark matter taking vague shapes that resemble humans, scorpions, and swords before [[MirrorBoss assuming the player's form]]. More shocking still, [[InterfaceScrew it blocks out its HP gauge with amorphous black masses]].
* ''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.)
*** ''Jigoku-hen'': The Shiseiten is a six-mouthed monstrosity that rivals even the Dimensional Monsters in appearance.
* 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 Primagen in ''VideoGame/{{Turok}} 2'', who threatens to [[SealedEvilInACan break out of his prison]] and [[EarthShatteringKaboom unravel the fabric of the universe]]. There's also Oblivion, another Abomination who is the BigBad of the third game.
* The Myrmecols from the [[UFOAfterblank UFO series]] are a pretty-much-textbook example: they're enormous, spacefaring creatures with the power to control the populations of entire ''planets'' on a regular basis as part of their reproductive cycle.
* PlayedForLaughs in Japanese Super Mario World hack VIP MIX 2. The final boss is supposedly the creator of the game himself, who appears as a cluster of 2ch memes.
** In 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. They are behind some of the truly nastier fellows who originated in Azeroth, such as corrupting Neltharion into Deathwing along with his entire dragonflight, corrupting Queen Azshara, the most powerful Night Elf sorceress, and creating the Naga, the silithid, the qiraji, and the nerubians. They're also the (partial) creators of Humans, some Giants, Dwarves, Gnomes, and Troggs by 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.
*** 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'', Ragu O Ragula can be defeated using ''[[DidYouJustPunchOutCthulhu only Brad]]''. What does that make the titular Hero of Slayheim?
** 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 were created when the humans who stole the Black Key attempted to recreate White and Black Emelas.
* ''YumeNikki'' takes place entirely in a girl's demented nightmares, and it shows. Between the [[MemeticMutation infamous]] Uboa, the {{screamer}}-like event [[FanNickname generally known as]] "FACE", almost every inhabitant of the White Desert, the strange {{Mayincatec}} figures floating around beneath the floor, and the assorted other [[OurMonstersAreWeird bizarre monsters]] inhabiting corners of her head, Madotsuki could give more than a few CosmicHorrorStory writers lessons. Whether any of them are ''real'' outside her head is a matter for WildMassGuessing, however.
* One of the religions in the ''VideoGame/{{Civilization}}'' mod ''FallFromHeaven'' is called Octopus Overlords. The priests use homeless 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.
