[[caption-width-right:254:Meet the [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=2093 Cosmic Horror]].]]

* ''BetrayalAtHouseOnTheHill'' has, as one of its 'haunt' scenarios, 'The Stars are Right'. Just guess what survivors are trying to stop and what the traitor is trying to do.
* Naturally, Chaosium's ''TabletopGame/CallOfCthulhu'' game is just ''full'' of them. One of the basic stats of [=PCs=], along with the normal STR, DEX, CON, WIS, INT and such, is SAN. That's ''[[SanityMeter Sanity]]''. It's arguably the most important single stat unless you ''want'' to keep rolling up new characters. And driving the trope home, increasing your Cthulhu Mythos skill ''directly'' [[DrivenToMadness reduces the extent to which]] [[GoMadFromTheRevelation your lost Sanity]] can be regained. TheseAreThingsManWasNotMeantToKnow indeed.
** In addition to Franchise/CthulhuMythos beings, several {{Canon Foreigner}}s originated from this game, including ''Arwassa'', ''Baoht Z'uqqa-Mogg'' and groups of lesser Outer Gods.
** There's a board game based on Call of Cthulhu by Fantasy Flight called ''TabletopGame/ArkhamHorror'' which has tokens for hit points, knowledge of other worlds, and (you guessed it) sanity. Every turn, there's a high chance of a gate opening to another universe, and as more gates open, more monsters come flooding through... and as the game progresses, the Doom Count slowly rises. If it gets high enough, the Ancient One (Cthulhu or one of his cousins) appears and the players have to battle it. (Each EldritchAbomination has special powers -- Azathoth's power is "if summoned, the game is over. [[RocksFallEveryoneDies Azathoth destroys the world.]]")
** The [[CollectibleCardGame CCG]] based on Call of Cthulhu (also by Fantasy Flight) has loads as well, although it's actually possible to see a game played in which they don't appear. Just not likely. (Sanity is too valuable as an attack vector.)
* ''TabletopGame/CthulhuTech''. An RPG set about 80 years in the future after the Mi-go (or rather, [[SpellMyNameWithAnS Migou]]) have attacked Earth and the Great Old Ones are stirring. It combines Creator/HPLovecraft with ''Anime/NeonGenesisEvangelion'' (what with the gigantic biological weapons called Engels that pilots mentally sync to and ride in their spines). It also throws ''{{Guyver}}'' into the mix, with abominable {{Exp|y}}ies of Guyvers and Zoanoids (you can actually play the former - and the latter, with the advent of later books).
* ''Dragon Warriors''
** Balor, the god of darkness. A humanoid being, but of such immense size and power that he can rampage across the world unstoppably. It's a good thing that he's [[SealedEvilInACan entombed in magical ice.]] His cultists, [[ElementalPowers the Darkness Elementalists,]] are granted some of the best elemental spells.
** From the same setting, the ''Blood Sword'' campaign/series reveals there are others, such as a trio of truly hideous demon-things that were worshipped in the [[FantasyCounterpartCulture Middle-East equivalent]] before the spread of their [[CrystalDragonJesus Crystal Dragon Islam]] and [[EvilSorcerer the Archmagi of Krarth]], whose return from the void between the stars to their ruined fortress of Spyte heralds TheEndOfTheWorldAsWeKnowIt; the battle againt just ''ONE'' is [[ClimaxBoss the hardest fight in the series]].
* ''TabletopGame/DungeonsAndDragons'' has whole races of Eldritch Abominations; from 3rd edition onwards, they have been increasingly linked with the Far Realm, [[EldritchLocation an impossibly vast, incomprehensible place]] far beyond the cosmology of most ''D&D'' settings. A 3.5 sourcebook, ''Lords of Madness'', gave greater detail to the "Aberration" creature type, which is mainly used for such creatures (many of the weirder/most horrible Outsider-type creatures also count).
** Although considered a magical beast rather than an aberration, the Tarrasque counts as one. It's a {{kaiju}} creature, arguably a Franchise/{{Godzilla}} {{expy}}, that spends centuries or even millennia at a time asleep. And when it wakes up? It eats. ''[[ExtremeOmnivore Everything]]''. Entire empires are wiped off the map as it rampages, devouring animals, plants, people, buildings, mountains, everything in sight! It rages for days on end, then literally sinks back into the earth to sleep again, just melding with the soil until its hunger strikes again. Oh, and this thing? ''It cannot be killed''. By '''anything'''. Even if you get past its [[NighInvulnerable insanely tough scales]], its HealingFactor is so potent that no weapon forged by any power can slay it. The only way to destroy it in older editions is to make use of the Wish or Miracle spells... that's right, you need to use the ultimate InUniverse RealityWarper spells to render it DeaderThanDead before it can die. In 4th edition? You simply can't kill it. '''Period'''.
*** The 4th edition guide hints that if it can't meld with the planet again, it might be able to die. Of course, getting this thing off-planet is easier said than done...
** One of the various backstories of Asmodeus, the Lord of Nessus and King of Hell, is that he is actually one of these. What others see when dealing with him [[FightingAShadow is actually an advanced illusion]]. Asmodeus' real body is that of a titanic, ''miles long'' serpentine creature who is still injured from being thrown into hell. Because he was some sort of [[TimeAbyss primordial entity who predated the Gods]] and who created the Nine Hells when the Gods threw him into them.
** The various Obyrith subspecies existed [[TimeAbyss since before the dawn of time]], often have incomprehensible biologies, and just glancing at one is enough to induce new phobias or temporary insanity. One of the oldest horrifies ''reality itself'' and can ''kill'' [[BrownNote if you get a glance]] at [[YouCannotGraspTheTrueForm its true form]].
** The ''TabletopGame/EpicLevelHandbook'' for 3rd edition brought us the Abominations: malformed offspring of deities which desired to destroy all reality. Among the most horrific of them are the Atropal, which are the undead remains of stillborn godlings.
** Neth, The Plane That Lives. A whole freaking demiplane that is ALIVE, introduced in The Manual of The Planes. It qualifies as both an EldritchAbomination and an EldritchLocation. The Far Realm suggests that it contains creatures possibly just as large or maybe even larger, leading to the idea that Neth is one such native of the Far Realm that just so happens to have a portal to the Astral Plane inside itself. It learns by absorbing the denizens of other Planes that visit it.
** The {{Time Abyss}}es called Aboleths don't worship anything, but they ''respect'' beings they call the Five Elder Evils. These are [[{{Expy}} thematically based on]] Creator/HPLovecraft horrors and include flames surrounding a body that will [[GoMadFromTheRevelation drive you mad if you see it]] (if it does not kill you outright), a ball of sentient goo the size of a planet, and a drilling subterranean squid/centipede thing that appears to be eating its way very, very slowly through the crust of the planet. [[BrownNote Whose feces will make your head go wonky if you get too close to it.]].
*** 4e suggests that aboleths aren't even intelligent, thinking creatures; rather, everything they do is the result of a guiding, species wide instinct that is unfathomable by mortals.
*** While 3.5e and backwards states that aboleths are intelligent and thinking beings, but operate on concepts entirely beyond mortal comprehension; their intelligence is described as a vast and endless ocean, while that of a regular human is but a drop of water. See {{Blue And Orange Morality}}, or ''Lords of Madness''.
*** Aboleths have enough parallels to abominations of the Franchise/CthulhuMythos that the question was directly addressed in the ''Lords of Madness'' sourcebook:
---->Readers will notice a thematic resemblance between the aboleths, the Elder Evils, and various creatures or beings found in the stories of H. P. Lovecraft. This is, of course, completely intentional.
** The [[TabletopGame/{{Eberron}} Daelkyr]]. Extradimensional invaders who mess with the fabric of reality [[ForTheEvulz for shits and giggles]]. They also like to [[EvilutionaryBiologist mess with mortal biology like a kid plays with Play-Doh]].
*** For some reason, all of the six Daelkyr who were trapped on Eberron look like [[HumanoidAbomination unnaturally handsome male humans]] [[RedRightHand with one feature changed]]. The Master of Silence, the Daelkyr BigBad in ''Literature/TheDragonBelow'' Trilogy, has smooth skin where his mouth should be. According to WordOfGod, however, the question is not to ask why daelkyr look so humanoid, but to ask why ''humanoids'' look so ''daelkyr''...
*** Speaking of Eberron, there's also the Quori, horrifying monstrosities from the plane of dreams with very strong PsychicPowers (usually of the MindControl or MindRape varieties) and the ability to possess mortals; they've already conquered/subverted almost a continent and would really like to take over the rest...
** One of the last 3.5 books Wizards released is called "Elder Evils", which features a guide of how to create your ''own'' eldritch abomination, as well as several examples of BigBad Eldritch Abominations, including Ragnorra, the MookMaker SpaceWhale with an EvilutionaryBiologist streak; Pandorym, the living ForgottenSuperweapon with a personality you don't want ''anywhere near'' a ForgottenSuperweapon; Atropus, the [[OmnicidalNeutral undead planetoid]] (who is the quasi-sentient remains of the thing that birthed the universe); Kyuss, TheWormThatWalks (that's his ''actual title''); and [[AlienInvasion the Hulks of Zoretha]]. It also updates/reimagines one of D&D's earliest published examples of this trope: Zargon, a tentacled aberration revered by a fanatical drug-cult in ''B4: The Lost City''.
** 4th Edition has the Primordials -- a primeval race of elementals who ''created the universe'' and are powerful enough to ''destroy gods''. They would like nothing more than to [[TheEndOfTheWorldAsWeKnowIt destroy said creation]], since as their nature are as elementals dictate, they wish to continue an endless cycle of death and rebirth. Most mortals are perfectly fine with the world as it is now, especially since said death and rebirth would include them.
*** 4E gives Warlocks the Star Pact power source, which involves beseeching strange otherworldly creatures that lurk behind specific stars for power. A lot of fluff text suggests that they become a little unhinged. Furthermore, a Dragon Magazine supplement includes an Epic Destiny where you become one of these strange otherworldly entities. It also describes the aforementioned stars and notes their "unnatural" qualities, particularly one that you're better off not looking at for long.
*** ''The stars themselves'' are Eldritch Abominations in 4th edition. And some of them have the ability to create avatars of their power, to the point where even ''black holes'' can create such avatars. [[DarkIsNotEvil And at least one of those stars is good]]; Ulban the Messenger is a mostly benevolent comet god who wants to change the future, but his Star Spawn was featured in the Monster Manual Three, and oh looky, it's evil aligned.
** While it mostly deals with Gothic horror, the ''TabletopGame/{{Ravenloft}}'' campaign setting features an eldritch abomination in the form of [[spoiler:Gwydion the Shadow-Fiend, Darklord of the Shadow Rift. He became trapped between realities when a planar gate collapsed on him, and really, really wants out. His full appearance is unknown, but what has been seen causes even TheFairFolk to go mad.]]
*** The Dark Powers, the force(s) that created Ravenloft itself, since their actual nature, methods, and motives are entirely unfathomable. As well, the Nightmare Court could qualify.
*** Regular old fiends (demons, etc.) were described in eldritch abomination terms in ''Van Richten's Guide to Fiends'' for this setting. It didn't seem inappropriate. Horrifying creatures of great power and alien minds from other realities...
** Many of the CthulhuMythos deities (such as Cthulhu himself) have entries in the 1st edition Deities & Demigods supplement -- and the way 1st edition rules worked, a high enough leveled player character could, in fact, [[DidYouJustPunchOutCthulhu punch them to death.]]
** Basic D&D was no stranger to Eldritch Abominations. Aside from the Nightmare creatures (like the Diaboli and the Malphera), whose physiology was utterly alien and horrific to humanity, there were also the creatures from the Vortex, a place beyond all dimensions and planes of existence, who could cause inexplicable phenomenons with their mere presence. Even the [[PhysicalGod Immortals]] are afraid of such things.
** TabletopGame/{{Greyhawk}} has a few of these:
*** Dread Tharizdun, a monstrosity that threatens all of existence and that the rest of the gods were forced to cooperate to imprison. Since 3E, Dread Tharizdun has evolved to become a more general Abomination for the whole D&D cosmology.
*** An entity that actually exists on Oerth itself is the Mother, a bizarre entity served by a colony of degenerate and inbred humans who found it while they fled the destruction of their old empire. Physically, the Mother looks like a large mass of disgusting white ooze that slithers across the walls, floor, and ceiling of the caverns it inhabits, with the ability to drain the life out of anything it makes physical contact with. Unlike the other examples, it's possible for the PlayerCharacters to actually [[DidYouJustPunchOutCthulhu punch the Mother out]], as it's mentioned in one of the adventure ideas provided by Creator/GaryGygax in the original 1983 Greyhawk boxed set.
** The Qlippoth in the ''TabletopGame/ScarredLands'' setting, created third-party company (a WhiteWolf subsidiary, unsurprisingly) are Obyrith with the SerialNumbersFiledOff (or rather [[OlderThanTheyThink the reverse]]; see the Obyrith entry above), and cosmology-wise, the Abyss is a cancerous sore that's wrapped itself around reality. And the qlippoth may just originate from whatever is beyond it...
*** The Far Realms equivalent, called the Dark Tapestry, isn't very far, relatively speaking - it's actually ''The Void Between The Stars'', and to top it off, it's the domain of Lovecraftian entities, Azathoth and Yog-Sothoth included.
** The D20 setting ''DragonMech'' has the lunar gods, mysterious entities from the [[ColonyDrop rapidly-descending moon]]. There are three main ones: Andakakilogitat, lunar god of dragons, a squirming mass of dragon parts; Erefiviviasta, lunar goddess of flight[[note]]"goddess" because there are ''slightly'' more female characteristics than male ones[[/note]], who is not described; and Seroficitacit, god of change, which is a perpetually mutating and somewhat insane mass of flesh.
** The [[http://www.rpgnow.com/product/3481/Immortals-Handbook--EPIC-BESTIARY-Volume-One?it=1 Immortals Handbook: Epic Bestiary]] 3rd-Party rulebook designed to make the best of the {{Absurdly High Level Cap}} features the 'Nehaschimic Dragons', beings who are described as 'nightmarish interdimensional creatures extraneous to the universe itself... transdimensional tapeworms writhing within the body of the [universe], a surreal symbiosis of reality and unreality'. In the rules, all Nehaschimic Dragons have the '[[RealityWarper Alter Reality]]' power, stupidly high {{Damage Reduction}}, [[AntiMagic immunity to all but a few]] [[AchillesHeel specific types]] [[AntiMagic of magic]] [[ElementalRockPaperScissors and elemental damage]], can travel at the speed of light ([[FasterThanLightTravel or faster]]), [[SuperSenses see all the way to the edge of their]] [[AnotherDimension current universe]], [[{{Sizeshifting}} grow to become bigger than]] [[AlienGeometries the universe]] ([[YourMindMakesItReal at least from your perspective]]) and their very presence causes [[GoMadFromTheRevelation permanent insanity]] for everything within miles. Unfortunately, or perhaps fortunately, there was only one Nehaschimic Dragon ever published, the Nexus or Wormhole Dragon. It has a BreathWeapon with a [[NoSavingThrow flat 50% chance]] (or higher) to shunt you into an AlternateUniverse, [[BornLucky power over probability]], and an aura of '[[PowerNullifier Unknowing]]' which can even cause the universe to [[RetGone forget you]] if you're weak enough.
* In the world of ''EarthDawn'', the cyclical ebb and flow of magic periodically allows Horrors to slip from their own dimension into the world and devour anything that moves. If you're lucky, they will devour your body before they start on the good stuff. Luckily for the world, [[TheMagicGoesAway magic energies are on the decline]], so the survivors the last cataclysm the Horrors caused have just to outlast their ability to keep existing in our world for a generation or two before they're all gone.
* ''TabletopGame/{{Shadowrun}}'' is more or less on the opposite end of the scale from ''EarthDawn,'' with ''Shadowrun'' a world where [[TheMagicComesBack magic is on the increase]] and the Horrors not terribly far behind. While there's at least one group working to speed the process, there's also [[OurPresidentsAreDifferent others]] working to delay things, with the hope that this new-fangled technology thing can prevent TheEndOfTheWorldAsWeKnowIt.
* ''TabletopGame/EclipsePhase''. Encountering ''any'' alien life triggers a stress check, and the only canon sapient species that transhumanity has contacted resemble [[StarfishAliens giant slime molds]]. And then there's the [[DeusEstMachina Seed AI]] that can potentially achieve god-like intelligence, and the effects of some strains of the [[TheVirus Exsurgent virus]] are not [[BodyHorror pretty]].
** Warning, GM only info ahead: [[spoiler: the ETI, [[AbusingTheKardashevScaleForFunAndProfit a Kardashev III or maybe IV entity]] that created the Exsurgent Virus. Described as being [[TimeAbyss eons old]] and capable of megascale engineering with an understanding of physics, matter, energy, and universal laws that makes all of transhuman knowledge seem insignificant. And for some reason, it has seeded the galaxy with probes that infect near-singularity intelligences with civilization destroying viruses.]]
* WhiteWolf's ''TabletopGame/{{Exalted}}'' has some bizarre entitites which originated in the [[PrimordialChaos chaotic non-place]] outside of reality itself.
** The Primordials came out of said PrimordialChaos and ''built'' Creation, with all its gods to take care of it, so that they had time to [[MemeticMutation smoke magical crack.]] Their minds are so vast that they're divided between entire hierarchies of multiple souls, each of which has a mind of its own and multiple lesser souls with minds of ''their'' own.
*** Most of the Primordials that didn't get killed are now the Yozi, [[DemonLordsAndArchDevils demon princes]] who have had their very beings and souls turned inside out and who live in [[GeniusLoci the broken body of their leader]]. They wish to turn Creation into Hell as part of a rather demented plan to escape their prison by expanding it.
*** The Neverborn are ''dead'' Primordials that you have to meet face to architecture. Killing them broke the universe and shat the entire Underworld into being.
*** Autochthon, a living non-Yozi Primordial, is a giant hollow machine-deity approximately the size of a planet, mostly made of steampunk (and he's a good guy. Sort of.)
*** The three kinds of Primordial Exalted -- Alchemicals, Infernals, and Abyssals -- are gradually evolving into something closer to their patrons. Alchemicals gradually turn into cities, but the others have only existed about three years and, as such, have had nowhere near enough time to turn into... whatever it is they end up becoming.
*** ''Return of the Scarlet Empress'' revealed Yozi charms which define the ability of Primordials to exist in their [[GeniusLoci worldform jouten]][[note]]Technically, ''all'' of a Primordial's jouten are defined by charms (as are all of their capabilities and personality aspects). The most accurate way to describe a Primordial is as a sentient collection of charms built around a central theme.[[/note]] Which a Green Sun Prince can learn. Which means that ''[[TranshumanAliens every Green Sun Prince is actually an infant Primordial]]''.
*** To up the fun, PDF supplement ''The Broken-Winged Crane'' gives the Green Sun Princes another path to transcendence, the Heresy charms. Instead of turning yourself into a world, you gain the ability to create worlds within yourself.
*** Once the Exaltation shard becomes redundant, it is released to be implanted in another Infernal...
** In addition, there are also TheFairFolk. The ones that aren't pretending to be something human-shaped for fun are most easily understood as formless living stories who either want to [[ApocalypseHow return Creation to the primordial Wyld it used to be]] or just look at Creation until they get bored and wander off, but ALL of them like to eat the dreams and souls of whatever mortals they can catch.
*** The purest Fair Folk horror would be the hannya - a special kind of Unshaped that is formed from a narrative of predation. Even ''the other Fair Folk'' are afraid of the hannya.
* ''TabletopGame/FadingSuns'' has the [[NamesToRunAwayFromReallyFast Void]] [[SpaceIsAnOcean Krakens]], who dwell in interstellar space and are [[NothingIsScarier never actually physically described]]. The only sign of their existence is the frequent loss of ships that don't use the [[PortalNetwork Jumpgate system]] and instead rely on conventional, non-FTL propulsion (such as First Republic generation ships), which sometimes arrive at their (long since settled, due to Jumpgates) destination with ruptured hulls and ''gigantic sucker marks'' on them, as well as distress calls mentioning unimaginable, horrific ''things'' before being cut off in mid-sentence. The alien races of the setting seem to have had trouble with the Void Krakens as well in the past. The good thing? Apparently the beings cannot enter star systems - it's theoretized in-universe that either the Jumpgates or the stars themselves repel them. The bad thing, which incidentally lends credence to the second theory? Since the fading suns phenomenon began, Void Kraken attacks have again begun after millenia of inactivity. And not only begun, but increased exponentially...
* The ''Gumshoe System'' has openly embraced the concept for its first settings - there is ''TrailOfCthulhu'', their own take on the [[CthulhuMythos Mythos]], but there is also the basic campaign world for ''Esoterrorists'' and ''Fear Itself'', which they have given the [[SarcasmMode cutesy moniker]] of '''[[NamesToRunAwayFromReallyFast World of Unremitting Horror]]'''. The monsters, most of them described in the supplement ''The Book of Unremitting Horror'', are, for the most part, ghastly {{humanoid abomination}}s that seem straight out of one of Creator/CliveBarker's more horrifying stories, many also blurring the line with other monster types such as [[OurDemonsAreDifferent demons]], [[TheUndead undead]], and [[TheFairFolk fairies]], the worst being {{Reality Warper}}s from "The Outer Black"; many others [[TheHeartless feed on and/or are created by the worst aspects of human nature]] (for example, [[SnuffFilm the Snuff Golem]]). The entries, which include numerous fiction pieces and detailed descriptions of how to identify the things' depredations through forensic sciences, all add up to some serious NightmareFuel.
* ''{{GURPS}}: Fantasy'' treats Tiamut as this, giving stats for a minor avatar of hers that, while not particularly odd looking (it's an enormous dragon with four eyes), can still cause terror from just looking at it. Said avatar automatically regenerates every year, making the effort of trying to kill it futile. To get rid of it permanently, you'd have to track down and kill the real Tiamut... who is half the size of the universe (about 2.24* 10^18 HitPoints), so good luck with that. There's even a Lovecraft quote after the stat block.
** ''GURPS'' has a few more from different settings and splatbooks: ''GURPS: Cabal'', with its cosmology based on the qabbalah's Sephirot, has the creatures of Qlipoth and its Ur-Lords; ''Creatures of the Night'' has the godlike Betweeners, the force called "[[DarkIsEvil the darksome]]", which is responsible for the creation of the literal organ-farmer [[SplitPersonality Darklings]], and many of the non-undead creatures described; a few licenced settings (like ''Cthulhupunk'' and ''Literature/TheWarAgainstTheChtorr'') have their own native abominations; and ''Infinite Worlds'', the meta-setting that ties TheMultiverse together, not only makes ''all'' the previous settings inter-accessible, but also has at least one world (Taft-7) where humanity never evolved in the first place because of Great Old One (or similar) influence 50 million years back - and although they're long gone, they left enough "Fun Stuff" behind (and the risk of attracting their attention is great enough) for the agencies overseeing interdimensional travel to quarantine the world from any travel there whatever the reason.
* While [[HumansAreCthulhu our nature]] in ''{{Kult}}'' allows us to kick most super beings with ease once awakened, the Forgotten Gods are different stories. These beings represent principles incomprehensible to humanity and are powerful enough that they do not even care about the plans of the [[{{God}} Demiurge]] or [[{{Satan}} Astaroth]].
* ''MagicTheGathering'' has several kinds of those:
** The more mundane ones, which have been around for some time, have the "Horror" or "Nightmare" creature types. Not all of them fall under this trope, but a fair number do. For example, the [[http://www.wizards.com/mtg/images/tcg/products/alarareborn/oz5ev5t1ru_EN.jpg Nemesis of Reason]]. Many of them either kill creatures simply by being them (in a way reminescent of [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=202486 Terror]], an old and classic spell for killing creatures), or attack the cards in your hand (representing your thoughts) or deck (representing your memories), which can eventually kill you.
** [[http://www.wizards.com/magic/images/mtgcom/arcana1000/1119_maritlagetoken.jpg Marit Lage]] is an ancient, betentacled SealedEvilInACan. The card [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=121155 Dark Depths]] allows you to ''unseal'' her. She's strong enough to kill a player in one hit if you manage to do so.
** The Zendikar block storyline was about the awakening of a race of abominations called the Eldrazi, which had been [[SealedEvilInACan locked away]] a thousand years ago by Sorin Markov and two other planeswalkers. The block culminated in the Rise of the Eldrazi as Sorin failed to re-seal the prison. Unlike all other non-artificial creatures in Magic, the Eldrazi don't have a color: they are beyond the concepts the rest of the known Multiverse abides to. In addition to their [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=261321 entirely]] [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=193452 alien]] [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=193632 look]], they also annihilate a large part of your opponent's ressources just by attacking, before they can even try to stop them. Eldrazi are also associated with some non-creature spells, which have very telling names such as [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=193658 All is Dust]] or [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=198296 Not of This World]].
** An argument can be made to include the all powerful Dragon known as [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=260991 Nicol Bolas]]. [[spoiler:Originally he was simply one of five Dragons known as the [[OurDragonsAreDifferent Elder Dragons]]. Later, because he bore the spark, he ascended to the status of a Pre-Mending Planeswalker. He was quite possibly the very FIRST planeswalker in the history of that world to boot. Later, when the Mending came, he was one of the few Pre-Mending Planeswalkers to survive the process of the Mending with his spark intact. This allowed him to become one of the Post Mending Planeswalkers. Add to this the fact that as the oldest Planeswalker, he really wouldn't rest with the power-level of the Post-Mending Planeswalkers, so he set about executing a series of {{Deus Ex Machina}}'s with the sole purpose of getting him back up to Pre-Mending power levels. He succeeded in his efforts.]] Thus rendering him the single most powerful Planeswalker at the current time, and thus truly worthy of the title "Eldritch Horror."
* The Lords of Cthul from ''{{Monsterpocalypse}}'' are the Cthulhu-esque, Godzilla-sized avatars of powerful extradimensional monsters... who get [[DidYouJustPunchOutCthulhu bodyslammed]] regularly.
* In the TabletopGame ''MonstersAndOtherChildishThings'', one of the types of monsters used in its dark and twisted take on {{Mons}} are Eldritch Abominations. The non-statted sample monster Dewdrop is an Eldritch Abomination take on a unicorn, while one of the statted sample monsters is a Lovecraftian monstrosity merged with a teddy bear named [[ShoutOut Yog-So`Soft]]. Both these and the more "normal" monsters tend to cause bouts of panic and madness in people who see them as well, further adding to it. There are also a few non-{{Mon}} antagonists that are also abominations.
* Well, though the RPG of {{Mortasheen}} isn't out yet, there are three creatures in the setting so powerful they might as well be these. Called [[NamesToRunAwayFromReallyFast The Destroyers]], these unfathomably powerful weapons are as follows.
** There is [[http://www.bogleech.com/mortasheen/hestermoan.htm Hestermoan]], a horrible Nuckleavee-esque monstrosity created "as an instrument of genocide against a civilization, and so effective that their very name remains unrecoverable". It is every variant of PlagueMaster rolled into one horrible monstrosity, including a HatePlague to boot.
** Then there is the [[http://www.bogleech.com/mortasheen/tormanshee.htm Tormanshee]], a creature that creates that can be best described as a neural network of MindRape. [[OhCrap And every mind it adds to the network increases its horrible mind rape radius]]. Oddly enough, it is also a NonMaliciousMonster, which just serves to make it even more disturbing.
** And finally, there is [[http://www.bogleech.com/mortasheen/mothneaser.htm Mothneaser]], an enormous pillar of flesh with such perfect control over its blood that it can create massive [[ShapeshifterWeapon Shapeshifter Weapons]], enormous Blood {{Golem}}s, and use victims as PeoplePuppets. And also, [[FromASingleCell even a single blood cell of its can multiply inside other creatures]] and consume them from the inside-out.
*** Oh, but we're not out of the woods yet, as there's a class of monsters based on the theme, called the Unknowns. These creatures include such lovely things as [[http://www.bogleech.com/mortasheen/psychodrome.htm a creepy interdimensional television "signal"]] [[TouchedByVorlons implied to have bounced off of]] [[EldritchAbomination Eldritch Abominations]]; [[http://www.bogleech.com/mortasheen/hobkin.htm a thing whose biology is]] [[BizarreAlienBiology so alien]] that nobody has the foggiest idea how the thing works; [[http://www.bogleech.com/mortasheen/xenogog.htm a diver-masked thing]] that can make itself intangible at will, spawns from AlienGeometries, and can see something [[UltimateEvil so horrible in television static that it breaks the TV in fear]]; [[http://www.bogleech.com/mortasheen/underfiend.htm a horrible thing that is the embodiment of]] Naughty Tentacles; and [[http://www.bogleech.com/mortasheen/avazoth.htm the]] [[http://www.bogleech.com/mortasheen/grenzo.htm Meteor]] [[http://www.bogleech.com/mortasheen/ziafel.htm Series]], [[BizarreAlienBiology which aren't even technically alive]].
*** The "honorary" Destroyer, [[http://www.bogleech.com/mortasheen/necromon.htm the Necromon]]. Originally just TheSymbiote, a unique mutation caused it to grow in size and intellect until it became a PhysicalGod with control over its smaller brethren, all of which serve as {{Amplifier Artifact}}s which also were the basis for an ''entire genus'' of monsters. It's [[LawfulGood friendly]], but it says something that the ''attempted'' replication of it is a capital crime in Mortasheen, on the basis of [[GoneHorriblyWrong what happens]]. The same people who banned this ''created'' the Destroyers, so something that scares [[NightmareFetishist them]] must be ''really'' bad.
* Spoofed in the ''TabletopGame/{{Munchkin}}'' Cthulhu stand-alone ''TabletopGame/{{Munchkin}}'' set and its expansion, The Great Cowthulu. It added a new dimension to the game in the form of the players being able to become cultists. And if everyone in the game became a cultist, the game was over as Cthulhu won. Also, one of the monsters featured is the very cute Chibithulu. Cthulhu also shows up as a monster in the original ''TabletopGame/{{Munchkin}}'' game (based on Dungeons and Dragons).
** Now with a second expansion, based on TheUnspeakableVaultOfDoom, with artwork by the webcomic's artist! [[CatchPhrase Yum Yum!]]
* The Unspeakable One from the Freedom City ''MutantsAndMasterminds'' setting. (It also provides Golden Age stats for an eldritch entity, although that barely qualifies - it may ''look'' like Cthulhu, but it doesn't drive you mad simply from looking at it.)
* WhiteWolf's ''TabletopGame/NewWorldOfDarkness'', published as Lovecraft's works are getting more influential, shows several of these.
** The True Fae of ''TabletopGame/ChangelingTheLost'' skirt the line between TheFairFolk and this, especially when taking into account the rules in the ''Equinox Road'' sourcebook. In addition to the traditional inhuman beauties and horned hunters, you might face a Fae that appears as a pool of sentient darkness, a squamous, be-tentacled ''thing, '' an entire tribe of ogrish monsters, or [[GeniusLoci the whole Arcadian realm itself.]]
** In addition to mentioning the below Chthonians, ''TabletopGame/GeistTheSinEaters'' supplement ''Book of the Dead'' introduces the Leviathan, the Kerberos of the Ocean of Fragments, who pretty well embodies this trope. It's an [[KrakenAndLeviathan impossibly vast sea creature]] of some sort -- it's assumed to be a [[EverythingsSquishierWithCephalopods cephalopod]], but that's just because it has tentacles; it's too big for anyone to ever see enough of it to make out its true form. ''Every'' human in the world has had nightmares of it lurking beneath them in an endless ocean, even if they've forgotten them. It cannot be killed or placated, any more than the tide or any other force of nature, and stats are provided solely for the purposes of escaping it or inconveniencing it enough to drive it off temporarily. Fortunately, it's rarely seen -- to the point that most people think the Dead Dominion's only other notable inhabitant, the Admiral, is actually its Kerberos.
** With the release of the ''God-Machine Chronicle'', we now have the titular [[DeusEstMachina God-Machine]]. Let's put it this way: Literally the ''first quote'' in the book is ClarksThirdLaw, and it's implied to have created the ''concept'' of technology on Earth so humans could create spare parts for it. Bonus points for being the most classically Lovecraftian being in all of both Worlds of Darkness: It isn't malevolent, it isn't cruel, it isn't even mindlessly destructive. It's just completely apathetic towards human existence.
** BIG ''TabletopGame/HunterTheVigil'' spoiler: [[spoiler:The Cheiron Group is run by ten of them, with [[HumanoidAbomination illusions of human beings]] to let them interact with people. It's the Storyteller's choice whether they're working to defend our world or are planning to exploit it for everything we've got.]]
** Abyssal entities from ''TabletopGame/MageTheAwakening'' come from what could best be described as an "anti-universe," a world that lives by rules wholly antithetical to those of Earth. Truly, however, the most horrifying thing about Abyssal entities is that the idea that beings of the Abyss always take such predictable -- horrifying and maddening, but predictable -- forms as "monstrous, unclean abomination" is actually a comfortable lie that Mages tell themselves to hide from the fact that the Abyss is, in fact, [[YouCannotGraspTheTrueForm in no way as banal and quantifiable as that]].
*** An Abyssal entity that's been known to sell a lot of prospective players on the setting is the Prince of 100,000 Leaves, a demon made of living anti-history whose first summoning [[RetGone rewrote history]] and spawned a cannibal cult that [[RetGone eats its victims out of history]] in an attempt to bring the world in line with the Prince's native timeline.
*** Oh yeah, and ''Imperial Mysteries'' has the reason for the strange predictability: each and every Abyssal being is [[FightingAShadow actually a resident and part]] of a Greater Abyssal Entity. You know what those are? ''[[OhCrap Semisentient stillborn universes]].'' The Prince is explicitly stated to be an example of one, with all his manifestations being him trying to replace all of reality. Now think: what kinds of beings gave birth to ''everything else'' in Intruders, since they aren't part of the Prince...?
*** There's also the Nemesis Continuum. It's the [[MadScientist scientific]] CosmicHorrorStory to the Prince's [[MadArtist perversion of the humanities]]. It's an altered set of the laws of physics. Bits of the material world it contaminates are [[RealityIsOutToLunch twisted]]; what if anything green was suddenly boiling hot, and the speed of light was slower than the speed of sound? It gets worse. The Nemesis Continuum is summoned by intelligent scientists "accidentally" (the book says that most proofs are found through indirect interference by [[EldritchAbomination acamoth]]) finding a proof for it, which then becomes true. And they become obsessed with finding more proofs. The best part? The Nemesis Continuum is apparently [[HyperspaceIsAScaryPlace the physical laws of the Abyss itself]], so to fight it on its own level, ''you probably need to infect yourself with them''. By the way, [[TheVirus it's also easier for a scientist to explain and thus prove a proof once he understands it...]]
** The {{Sourcebook}} ''Summoners'' includes some other examples, such as the Chthonians of the Underworld (known as the "neverborn" since they exist in the realm of the dead, but cannot be reliably said to have ever been alive) and certain Supernal beings.
** The sourcebook ''Second Sight'' has a pretty good chapter on building your own abomination, a MisanthropeSupreme or FallenHero to serve as their high priest, and a cult to worship them. The creation example is a being of dissonant sound. (Although one suggested weakness for this being -- music of unity -- seemed uncannily reminiscent of ''Film/{{Ghostbusters}} 2''.)
** The UpdatedReRelease ''God Machine Chronicles'' greatly expanded on the concept of the God-Machine -- [[AbortedArc which was referenced in some fluff in the original core book, then never spoken of again until this book]] -- which is further expanded upon in ''TabletopGame/DemonTheDescent''. It's a monstrously powerful, alien artificial intelligence of such vast power and scope that ''TheMultiverse'' is simultaneously a program it's running and part of its component infrastructure. It's a RealityWarper of literally god-like proportions, quite capable of creating entire cities from existence and retconning them into reality -- or [[RetGone retroactively erasing them from reality]].
** The Unchained, the titular characters of ''TabletopGame/DemonTheDescent'', are this as well. Unchained begin as sentient computer programs created by the aforementioned God-Machine as its servitors and messengers -- its "Angels". Somehow, though, they became self-aware and rebelled against the God-Machine, becoming "Demons". Though they feign a human existence, this "Cover" is literally only an artificial mask woven over their true alien natures, the remnants of the reality retcons that the God-Machine originally wove around them to disguise them as humans. Using their more potent abilities will slowly fray away and discard their Cover, or they can [[OneWingedAngel "go loud" and assume their monstrous true form]]. They [[DealWithTheDevil can form "Pacts" with mortals]], where they trade something the mortal desires for [[RetGone retroactively stealing some aspect of that mortal's existence]] and transplanting it into their own Cover -- at its highest level is the Unchained's equivalent of DemonicPossession. When a mortal trades an Unchained their soul, the Unchained can ''erase that mortal from existence'', taking their former life as the Unchained's new Cover.
* ''TabletopGame/GeniusTheTransgression'' has the Cold Ones, entities living at the end of time, who'd like to go back and experience things like heat and movement.
* ''TabletopGame/{{Nobilis}}'' has three main types. First, the True Gods - some of the earliest gods to come into being, to be found below the world in an enormous mass of tentacles and weirdness, [[InterplayOfSexAndViolence simultaneously fighting and mating with each other]]. Next, the Excrucians, beings of not-being from outside reality who aim to destroy the universe, and finally, the Actuals, the precursors to the True Gods - the movement like life, before it learned to live. The Actuals are vital to the existence of reality - but if one is summoned into the world, it will consume ''everything'' in a futile attempt to attain self-awareness if it isn't stopped. The True Gods, on the other hand, could quite possibly be the guys who empower the [=PCs=].
* In WhiteWolf's ''TabletopGame/OldWorldOfDarkness'', cosmic horror story is not the central theme of the game, but the authors love to incorporate Eldritch Abominations from beyond time and space into the setting, whose presence corrupts souls, drives people insane, or warps reality. To break it down a little:
** ''ChangelingTheDreaming'' gives us the Fomorians, ancient, formless primordials and lords over winter and dark dreams. They were banished to the depths of the Dreaming by the Tuatha de Danaan, but as Winter approaches, they've started to make their way back...
** ''TabletopGame/MageTheAscension'' has some of the patrons of the [[EvilSorcerer Nephandi]]. The Malfeans worship the Wyrm (see above), while the K'llasshaa worship the Outer Lords, broken alien beings who feed on negative emotion and who were supposedly the lords and masters of the world in its pre-history.
** In ''TabletopGame/VampireTheMasquerade'', most of the Antediluvians are still quite humanoid - in appearance, at least. But then you've got people like Ennoia (the Gangrel Antediluvian, a mass of animalistic features who is believed to have melded with the earth itself, rocked to sleep by its rotations like a babe in the cradle), Malkav (the Malkavian Antediluvian, willingly diablerized by his clan, existing in their head as a madness-linked HiveMind, and sometimes appearing in forms such as twelve identical little girls), Lasombra (believed destroyed, but instead he became one with the lightless Abyss that helps power [[CastingAShadow Obtenebration]]) and Tzimisce (a gigantic mass of sculpted flesh).
*** Which, in the case of V:TM, makes it only scarier, seeing as the central theme of the game is how a human is transformed into a monster and to what extent this transformation can go (and how it can be fought). Usually, the transformation is psychological - holding on to the last shreds of humanity is a necessity for a player character (unless he/she chooses a vampiric Path). But, with the Tzimisce, it is also physical, and ''willingly self-inflicted''. The scary thing about powerful Tzimisce, especially the Antediluvian itself, ''is'' that they were human once, and are Eldritch Abominations now.
** ''TabletopGame/WerewolfTheApocalypse'' gives us the Wyrm, originally one-third of the primal forces of existence and the blessed end of all things until it got caught up in the webs of the Weaver, at which point it turned its goals towards corruption and destruction in an attempt to weaken its bonds. Most of its servants are either subjected to eternal decay or [[GoMadFromTheRevelation driven mad by its wisdom]].
*** The Weaver itself is no slacker in this department either, though its particular set of strange and alien activities is actually more alien than the Wyrm, and thus less likely to single out the players for destruction.
** ''WraithTheOblivion'' has the Neverborn, forever-dead, eternally-dreaming lords of Oblivion whose scattered thoughts serve to drive and guide the [[TheHeartless Spectres]]. ''{{Orpheus}}'' gives us Grandmother, [[spoiler: the thing that ''created the Neverborn.'']]
* ''TabletopGame/{{Pathfinder}}'' has inherited many of D&D's aberrations, and also includes a number of actual monsters from the Literature/CthulhuMythos, but it still has a few unique horrors of its own.
** Like the Spawn of Rovagug, the monstrous {{kaiju}}-sized abominations spawned by the resident [[OmnicidalManiac God of Oblivion]] in an effort to destroy the world and set him free. Remember the Tarrasque? It's back in Golarion, it's even ''more'' unstoppable, to the point its InUniverse [[TheRedBaron appellation]] is "The Armageddon Engine", and it's just ''one'' of the Spawn. The others named consist of:
*** Festering Ulunat, The Unholy First -- An immense ten-limbed three-eyed beetle-monster that sprayed gouts of acid, chewed its way through mountains and could [[AntiMagic absorb spells]] before returning necrotic energies that drove spell-wielders into insanity.
*** Great Doom Chemnosit, The Monarch Worm -- A {{kaiju}}-sized SandWorm with DisintegratorRay EyeBeams and the ability to MindRape people into insane, ravening cannibals who [[AutoCannibalism will devour their own flesh if nothing else is available]].
*** Unyielding Kothogaz, the Dance of Disharmony -- A horrific slug-beetle abomination that spawned countless abominations in its wake and which reanimated its victims as a ravening ZombieApocalypse.
*** Wrath-Blazing Xotani, the Firebleeder -- An immense dragon-centipede made of [[MagmaMan living volcanic rocks and flames]].
*** Volnagur, The End-Singer -- A star-shaped monster suspended by an endless array of eternally rotting and regrowing random wings, which sings a ceaseless cry that drives the listeners into madness.
* Spoofed in ''{{Pokethulhu}}''. Yes, there are hideous, evil, non-Euclidean critters. But you can tame them and use them as {{Mons}} (and they still drive you to insanity).
* {{Rifts}} has a ''lot'' of these monstrosities in its ranks, and several different kinds are present on Earth. The first two world books alone (on {{Atlantis}} and South America) have the Splurgoth and the Vampire Intelligences. Both are functionally mountain-sized eyeballs with mouths and tentacles, but the Vampire Intelligences are arguably more dangerous; they are the ultimate source of all [[OurVampiresAreDifferent vampires]] throughout the Megaverse, and cannot even manifest themselves unless a sufficient number of vampires are already existing first.
* In Glorantha (as seen in RuneQuest and other sources), Chaos is like this. One major empire has an enslaved Chaos god/demon/thingy called the Crimson Bat. It's huge, it flies, it is covered with eyes, it glows with unholy energy, and it will eat your soul. It ''is'' crimson, and I suppose it's at least as much like a bat as it's like anything else... which isn't much.
* The Greater Titans of ''TabletopGame/{{Scion}}'' are beyond mortal ken. They're beyond ''divine'' ken. They are so divorced from reality [[LogicBomb (despite being incarnations of its primal concepts)]] that they had to divide their power among Avatars just to have a clue what they were doing. Each one is its own internal world. Worst of the lot, though, is Hundun, the Titan of Chaos. It alone of the Titans couldn't be bound, for doing so requires definition - and Hundun ''cannot be defined''. An easy way to enter Hundun is to have a God become the Void, the living embodiment of chaotic... and then jump in.
* The ''StarWars'' RPG has the [=DarkStryder=], a self-aware supercomputer created by a {{Precursor}}-type race that has created several species of its own and looks like [[http://images3.wikia.nocookie.net/__cb20080922130707/starwars/images/6/6b/DarkStryder.jpg THIS]] and the Mnggal-Mnggal, a sentient fluid adept at [[GrandTheftMe possessing bodies]] so horrible that even the Celestials (a {{Precursor}} race even more mysterious than the [=DarkStryder=]'s creators and believed to be nearly omnipotent) didn't want anything to do with it and sealed it away. WordOfGod from the creator of the latter abomination says it's supposed to be the same type of being as fellow ''StarWars'' abomination [[Literature/TheCrystalStar Waru]].
* Parodied in ''TabletopGame/{{Toon}}'' with the "Crawl of Catchooloo" setting, full of Slurping Horrors that can drive a typical Toon character ''sane''.
* ''TabletopGame/UnknownArmies'' [[spoiler: deliberately subverts this trope, at least in a way. What's scary about the universe isn't that it's so alien and vast and inhospitable to humans. What's truly scary is that]] [[ArcWords You Did It.]]
* ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'' both have the Chaos gods. Residing in the deepest layers of [[HyperspaceIsAScaryPlace the warp]], composed of [[TheHeartless every sapient thought and emotion]], they personify things like rage, scheming, despair and lust, but also things like honour, hope, resilience and love. They are so powerful and so incomprehensibly vast that they are utterly incapable of influencing anything outside of the warp, requiring their [[TheLegionsOfHell daemon hordes]] (all of whom are both separate individuals and aspects of the respective god) to recruit and kill in the material plane in their name.
** Tzeentch deserves special mention, because it is essentially the personification of cause and effect, meaning that as long as some things cause other things, it grows in power and influence. In a setting where all of the gods are intentionally or unintentionally malicious, Tzeentch is extra terrifying because sometimes his gifts DON'T have any kind of catch, and are distributed frequently based on whim and randomness rather than any kind of consistent evil -- there is literally no way to know whether you're part of a plan or not, and even if you think you are there's no way to know whether the plan is intended to succeed or fail.
** The C'tan of ''40K'' were literally [[TimeAbyss the oldest beings in the universe]], [[LightIsNotGood creatures of light]] that wrapped themselves around stars to feed off of them, and operated on a scale so vast they originally had no idea that ''planets'' existed, let alone the noisy little things living on them.
** While the Tyranids may seem more like a HordeOfAlienLocusts, the quintillions upon quintillions of ravenous beasts it unleashes are not actually individual beings, but merely a tiny part of the unimaginably vast single organism that is the Tyranid HiveMind. Utterly alien and of a near unprecedented power, capable of screwing with psykers and daemons within hundreds of light years of it, even people who have regularly fought and bested the horrors of the warp are terrified of such an implacable force.
** The original ''Warhammer'' has the Gods of Law, which are arguably more inhuman and, should the unlikely case of their victory occur, will turn the world into a stillborn reality where no change of any sort occurs. This is particularly more true to [[LightIsNotGood Alluminas]], whose requirements for his worship are extremely bizarre and who can cast a light that makes anything it touches unmoving and unchanging.
* In ''TheWhisperingVault'', the player characters are all minor Eldritch Abominations who act as a "police force" that apprehends and retrieves other abominations who have illicitly made their way to Earth. [[spoiler:Reality is also AllJustADream cooked up by those abominations who haven't gone rogue.]]
* The {{Mad God}}s from ''{{Witchcraft}}''. When they intrude on our reality, they spread [[TheCorruption taint]], which causes [[BodyHorror mutations]], [[GoMadFromTheRevelation madness]], and [[RealityIsOutToLunch a weakening of the veil separating universes]], potentially allowing more to come through. In the follow-up game ''Armageddon'', a ReligionOfEvil dedicated to one of them called the Leviathan is currently trying to conquer the world in its name; it's about halfway done. You know it's bad when most angels and demons get to the conclusion that [[EnemyMine they have to work together if they want any chance of stopping it.]]
* ''TabletopGame/YuGiOh'' TCG gives us the Alien archetype of monsters, the two strongest of which are [[http://yugioh.wikia.com/wiki/Cosmic_Horror_Gangi%27el Cosmic Horror Gangi'el]] and [[http://yugioh.wikia.com/wiki/Cosmic_Fortress_Gol%27gar Cosmic Fortress Gol'gar]]. Not quite as unspeakably horrible as some other examples, but still pretty terrifyingly hideous nonetheless.
** Worm Zero is a giant, moon-sized thing that looks like it has multiple heads sprouting out of itself, going by its effects, it can erase monsters by assimilating them, implant some hive mind knowledge into its user, or give birth to a worm. Said worms could also qualify, given their origins.
*** Gets even worse [[AllThereInTheManual when you read the Master Guide explaining the Duel Terminal storyline]]. He's a huge mass of combined Worms - not because [[FusionDance they merged into one]], but because ''[[DevourTheDragon he devoured his own ranks]]''. He's so powerful its mere existence warped time and space in the Duel Terminal world.
** One of Pegasus' signature monsters, [[http://yugioh.wikia.com/wiki/Relinquished Relinquished]], could also qualify. Its main gimmick is assimilating an enemy monster into its body, taking on its stats, and using it as a meatshield in the event that it might be destroyed. Even worse than this is Thousand-Eyes Restrict, a Fusion Monster that is summoned using Relinquished as one of the components; it does the same thing that Reliquished does, but also prevents all monsters except itself from attacking (the anime suggests that this happens because all other monsters are paralyzed by fear). On an unrelated note, Thousand-Eyes Restrict is so powerful as a card, it's currently illegal to use for official games.
** And then there's [[http://yugioh.wikia.com/wiki/Fusion_Devourer Fusion Devourer]]. Just look at the face-tipped tentacles.
** It may not look all ''that'' impressive when you look at its RealLife card [[http://yugioh.wikia.com/wiki/Unformed_Void shown here]], but in the anime, Unformed Void, used by the Shadow Giant in ''Anime/YuGiOhZEXAL'', fit the Trope, being a giant, hideous thing with dozens of cold eyes on tentacled stalks, and an amorphous void in the center.
* ''Silent Legions'', an upcoming product from Sine Nomine Publishing, is planned for modern-day delving into eldritch secrets, and will be compatible with ''TabletopGame/StarsWithoutNumber''. Core SWN, meanwhile, has the Shibboleth, strange aliens that can have any kind of weird shape, and which emanate an aversion field that prevents most species from realising the Shibboleth even exist, coming up with increasingly ludicrous rationalizations for the results of Shibboleth activity. Thankfully, a form of brain surgery that mimics the effects of [[CastFromHitPoints psionic torching]] can render people Clipped and immune to this field.
* ''[[TabletopGame/{{PoniesAndParasprites}} Ponies and Parasprites]]'' interprets the character of the Nightmare Force (the entity that corrupted Luna on the show and Rarity in the comics) as this. One of its Specialties is [[TheseAreThingsManWasNotMeantToKnow "Things Ponies Were Not Meant To Know"]] and one of its powers is [[TheColourOutOfSpace 'The Shadow out of Space']].
