History EldritchAbomination / TableTopGames

* 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.

* 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]].

* ''{{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.

* The Lords of Cthul from ''{{Monsterpocalypse}}'' are the Cthulhu-esque, Godzilla-sized avatars of powerful extradimensional monsters...who get [[DidYouJustPunchOutCthulhu bodyslammed]] regularly.

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 {{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. Said Supernal beings include the [[GodInHumanForm Ochema]], avatars of the [[BigBad Exarchs]] in ''Seers Of The Throne''. [[HumanoidAbomination Sure, they look]] [[{{Pride}} (and act)]] [[HumanoidAbomination like people]], [[StarfishAliens but look at them with Mage Sight]]...Unlike many examples, this is actually because they're ''less'' corrupted than everything else: [[CrapsackWorld The Fallen World]] simply [[DivideByZero can't handle]] [[{{Heaven}} Supernal]] beings like them...Although they stay significantly longer than and don't cause unintentional damage like Abyssal creatures, since they're ''supposed'' to be a part of the natural order of reality.

*** 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.

** There's also a board game based on Call of Cthulhu by FantasyFlight called ''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 Old 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 FantasyFlight) 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.)

* The infamous Immortal's handbook bestiary gives many examples, such as the neutronium golem, a creature so destructive that its mere presence can destroy reality. However, the most outright unsettling is the oft overlooked Alabaster, the current Amidah (Paragon of paragons). To give context, he's probably the second strongest creature in the book and is a fighter. He rose to his position through sheer skill and ambition and was a regular vampire (perhaps lord, at most) before gaining his title. He's also a level 177 fighter, in a game where most greater gods are level 40-80 at absolute most. He has a collection of 6 magical swords, most of which qualify to be on this page themselves (such as the sword that kills most wielders, but deals completely permanent damage.) and he wields all 6 at once, 3 floating due to magic and 3 wielded through skill alone, including the one that kills non cosmic level users. Alabaster has killed numerous gods by dragging them (presumable kicking and screaming) to his home plane, the Graveyard of Blades (which lives up to the trope)where he proceeds to brutally dismember anyone unlucky enough to end up there. The title of Amidah also gives him maximum ranks in every skill, wish at will and without XP costs (making him not only capable of being perfect at every task, but also warp reality) and the inability to fail on a natural 1, plus immunity to auto-hit mechanics. Fighting and winning is physically and mechanically impossible, even if the gods banded together to try and kill him.

* 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. Included in this list are the various unearthly patrons of the Nephandi from ''TabletopGame/MageTheAscension'', the Fomorians from ''TabletopGame/ChangelingTheDreaming'', the Neverborn Malfeans from ''TabletopGame/WraithTheOblivion'' (and Grandmother from ''TabletopGame/{{Orpheus}}''), the Wyrm from ''TabletopGame/WerewolfTheApocalypse'', and the Earthbound from ''TabletopGame/DemonTheFallen''. ''TabletopGame/VampireTheMasquerade'' has a lot less of this...although the Tzimisce and Gangrel antediluvians now ''resemble'' these, they started out human.

*** To make matters worse, the third edition gave us Mind Flayers of Thoon, illithids seriously twisted by a trip to the Far Realm (which itself is a breeding ground for {{Eldritch Abomination}}s) who worship something known as Thoon. Their numbers include various constructs, Thoon Disciples, Shadow Flayers (mind flayers that can turn invisible), Madcrafters of Thoon (sluglike monsters that can spawn constructs), Thoon Infiltrators (former slaves infected by a Far Realm parasite that can imitate regular beings and create thralls), and Thoon Thralls (slaves that can ''blow themselves up''...really, these guys are legit).

** One of the last 3.5 books Wizards released is called "Elder Evils", which features a guide of how to create your ''own'' CosmicHorror, 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 ''[[ExactlyWhatItSaysOnTheTin actual title]]''); and [[AlienInvasion the Hulks of Zoretha]].

*** Regular old fiends (demons, etc.) were described in cosmic horror or 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...

* In WhiteWolf's ''TabletopGame/OldWorldOfDarkness'', Cosmic Horror 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. Included in this list are the various unearthly patrons of the Nephandi from ''TabletopGame/MageTheAscension'', the Fomorians from ''TabletopGame/ChangelingTheDreaming'', the Neverborn Malfeans from ''TabletopGame/WraithTheOblivion'' (and Grandmother from ''TabletopGame/{{Orpheus}}''), the Wyrm from ''TabletopGame/WerewolfTheApocalypse'', and the Earthbound from ''TabletopGame/DemonTheFallen''. ''TabletopGame/VampireTheMasquerade'' has a lot less of this...although the Tzimisce and Gangrel antediluvians now ''resemble'' these, they started out human.

*** There's also the Nemesis Continuum. It's the [[MadScientist scientific]] CosmicHorror 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? [[ItGotWorse 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 fluff for the ''Zendikar'' block strongly hints at the existence of an ''entire race'' of Cosmic Horrors called the Eldrazi, all of which got locked away inside planets by a coalition of aforementioned planeswalkers. The name of the final set in that block? [[OhCrap Rise of the Eldrazi]].\\

** There was the original [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=2093 Cosmic Horror]] if you go WAAAAAY back to the ''Legends'' expansion. The art says it all.

** It also throws ''{{Guyver}}'' into the mix, with CosmicHorror {{Expy}}s of Guyvers and Zoanoids (you can actually play the former).

*** ''Return of the Scarlet Empress'' revealed Yozi charms which define the ability of Primordials to exist in their [[GeniusLoci worldform jouten]][[hottip:*: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.]] Which a Green Sun Prince can learn. Which means that ''[[TranshumanAliens every Green Sun Prince is actually an infant Primordial]]''.

** 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.

* ''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 NeonGenesisEvangelion (what with the gigantic biological weapons called Engels that pilots mentally sync to and ride in their spines).

** 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 literally created the Nine Hells when the Gods threw him into them.

*** The obyriths recently showed up in 4th edition with a revised backstory. Whereas the other demon lords seek to eventually destroy reality, the obyriths have already succeeded at least once before. The obyriths crippled their home dimension and started it on the unstoppable path to complete oblivion before even bothering to work out how they would survive the end of their own reality. They escaped to another reality and inadvertently created the demon lords. Basically, both the obyriths and the new demon lords plot to destroy reality, escape to a new dimension before the previous dimension completely collapses, destroy that new dimension, escape to yet another reality, destroy that reality, and so on until there are no more realities left.

*** It's not so much that they are arrogant; they are just older than pretty much all of the modern day Gods and have seen how they came to power. They pretty much view them as young upstarts who have no business messing with them or demanding worship from creatures far older than they are.

** Don't forget the [[{{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]].

*** 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 an entire continent and would really like to take over the rest...
*** Don't forget the Daelkyr's unique minions and mutants. As well as the 'standard' Dolgrim, Dolgaunt, and Dolgarr, Dragon Magazine also gives them Akleu, Dolgrue, Kyra, Opabinia, Xenostelid, and Xorbeast, each of which is its own flavor of ghastly.
** One of the last 3.5 books Wizards released is called "Elder Evils", which features a guide of how to create your ''own'' CosmicHorror, 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 ''[[ExactlyWhatItSaysOnTheTin actual title]]''); and, of course, [[AlienInvasion the Hulks of Zoretha]].

** 3.5 Edition also included the Alienist class. The class features made all your Summoning spells summon creatures from the aforementioned Far Realm, which took the forms of creatures you could normally summon, but took on a template that gave them more hit points, resistances, tentacles, or other deformities and the ability to shift into their "true(r) form", which scared everything like crazy. Further, your familiar became one of these creatures. Basically, you're calling tiny C'thuloid monsters. In addition to that, the caster who takes the class eventually starts ''becoming'' like one of these creatures, goes more than a little insane, and (with the timeless body class feature) is taken to the Far Realms by the unspeakable Eldritch Horrors when they would normally die of old age, specifically ''never seen again'' by people on the prime material plane. If you manage to reach the maximum level, you can cheat dying of age altogether, gain the "Outsider" trait, and become a HumanoidAbomination. Your character grows a tentacle or two at this point.

*** Also, 4E gives Warlocks the Star Pact power source, which basically 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.

*** Regular old fiends (demons, etc.) were described pretty much in cosmic horror or 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...

* The ForgottenRealms has three Elder Evils. Ityak-Ortheel the Elf-Eater was created when the blood of the orc god Gruumsh and the elven god Corellon Larethian merged. Its appearance is Lovecraftian (a massive body supported by three legs, tentacles everywhere). It lives in between the planes and is occasionally released by mad cultists (mostly of Malar) to, well, eat elves. And anything else in its way, of course, but it takes pleasure in destroying elven towns and cities and slowly devouring them over hundreds of years. The second is Kezef the Chaos Hound, who appears as a massive, skinless hunting dog, its coat covered in maggots. It hunts for the Faithful, those who worship a god, and kills them, and then the maggots swarm over the body before returning to Kezef. The soul of the person slain is utterly destroyed, and not even the gods can bring them back. It also [[DoesThisRemindYouOfAnything bit the hand off Tyr when the gods were trying to chain Kezef down]]. The third is Dendar the Night Serpent, a serpent several hundred feet long that came into being when the first creatures had a nightmare. It feeds on (and causes) nightmares of every sentient being in the world. As far as Eldritch Abominations go, Dendar serves a somewhat useful purpose: if she wasn't around, people would remember every nightmare they've had in exact, excruciating detail, never wanting to sleep again for fear of adding to their terror.

* The infamous Immortal's handbook bestiary gives many examples, such as the neutronium golem, a creature so destructive that its mere presence can destroy reality. However, the most outright unsettling is the oft overlooked Alabaster, the current Amidah (Paragon of paragons). To give context, he's probably the second strongest creature in the book and is a fighter. He rose to his position through sheer skill and ambition and was a regular vampire (perhaps lord, at most) before gaining his title. He's also a level 177 fighter, in a game where most greater gods are level 40-80 at absolute most. He has a collection of 6 magical swords, most of which qualify to be on this page themselves (such as the sword that kills most wielders, but deals completely permanent damage.) and he wields all 6 at once, 3 floating due to magic and 3 wielded through skill alone, including the one that kills non cosmic level users. It is noted that Alabaster has killed numerous gods by dragging them (presumable kicking and screaming) to his home plane, the Graveyard of Blades (which lives up to the trope)where he proceeds to brutally dismember anyone unlucky enough to end up there. The title of Amidah also gives him maximum ranks in every skill, wish at will and without XP costs (making him not only capable of being perfect at every task, but also warp reality) and the inability to fail on a natural 1, plus immunity to auto-hit mechanics. Fighting and winning is physically and mechanically impossible, even if the gods banded together to try and kill him.

* The {{Pathfinder}} system, being effectively D&D 3.75, has, of course, included these in its base setting, to the point of obvious AuthorAppeal. The Aboleths have an extensive undersea/underground empire, being [[spoiler:responsible for the rise and fall of that world's {{Atlantis}} stand-in]], and two of the basic pantheon's gods fit pretty well: Rovagug the Rough Beast, a ravenous, slavering monster from beyond whose reason for being is destroying the world, who had to be stopped by all the other gods working together to [[SealedEvilInACan imprison him inside the Earth]] (many dying in the struggle), and who periodically disgorges horrid spawn to devastate the surface (like [[{{Kaiju}} the Tarrasque]]); and Zon-Kuthon the Midnight Lord, whose jealousy towards his half-sister drove him to a self-imposed exile in remote corners of the cosmos, from which he came back changed into a thing of darkness, pain, and loss. Both tend to attract insane cultists (or to drive cultists insane, depending).
** ItGetsWorse, on several fronts. First: In this setting, Asmodeus is a reworked version of the above-mentioned backstory, only moreso: he is literally one of the two creator-beings of TheMultiverse and his wounds are from a fight with the other, good-aligned creator-being, [[DevilButNoGod who was killed in the battle]].

** Third: The Qlippoth are basically Obyrith with the SerialNumbersFiledOff (or rather [[OlderThanTheyThink the reverse]]; see the Obyrith entry above), and cosmology-wise, the Abyss is basically a cancerous sore that's wrapped itself around reality. And the qlippoth may just originate from whatever is beyond it...
** Fourth: Not only is there a Far Realms equivalent, called the Dark Tapestry, but it isn't very far, relatively speaking - it's actually ''The Void Between The Stars'', and to top it off, [[OhCrap it's the domain of literally Lovecraftian entities, Azathoth and Yog-Sothoth included]].
** Fifth: And of course, the deepest parts of [[BeneathTheEarth the Night Below]] are filled with gibbering, insane things, among them [[CthulhuMythos Gugs]], the aforementioned Aboleths and Neothelids (the latter of whom explicitely worship the Lovecraftian entities of the Dark Tapestry), the [[PuppeteerParasite Intellect Devourers]] (whose constant, horrific abuse of their [[AndIMustScream still-aware hosts]] just for [[SenseFreak sick]] [[ForTheEvulz kicks]] place them in CompleteMonster territory), and [[HumanoidAbomination the Urdefan]], an artificial semi-vampiric race created by the OmnicidalManiac [[NeutralEvil Daemons]] to carry on their KillEmAll agenda on the mortal plane. Fortunately, all those things are [[EvilVersusEvil locked in constant conflict with each other and the other dark forces of the underground]].

** And of course, the [[CollectibleCardGame CCG]] based on Call of Cthulhu (also by FantasyFlight) 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.)

*** 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 ''literally'' [[RetGone eats its victims out of history]] in an attempt to bring the world in line with the Prince's native timeline

** The [[FairFolk True Fae]] of ''TabletopGame/ChangelingTheLost'' deserve a mention. Now, they're more recognizable than their stablemates above, capable of great {{pride}}, vanity, and twisted creativity, but they are ultimately alien, incredibly powerful, and terrifying beings with [[EvilCannotComprehendGood no concept of empathy, kindness, or selflessness]], capable of rending souls and striking pacts with aspects of reality itself, and within their [[RealityIsOutToLunch home dimension]], they are capable of [[RealityWarper just about anything]] and can twist their kidnapped human subjects to meet their needs. That they happen to have inspired FairyTales perhaps only makes them ''more'' frightening. And do you wanna know how they're born? [[spoiler: [[AndThenJohnWasAZombie No. No, you don't.]]]]

*** Did we also mention that once the Exaltation shard becomes redundant, it is released to be implanted in another Infernal...?

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 all things chaotic...and then jump in.

* 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 literally AllJustADream cooked up by those abominations who haven't gone rogue.]]

** For those who don't play [=MtG=], a brief explanation: the deck, generally consisting of 60 cards, represents the player's spell reserve and memory remaining. So, effectively, everytime the Nemesis of Reason even ''looks'' at you funny, you ''lose one sixth of your mind''. No questions. And Marit Lage? She is 20 times as strong and resistant as one of the heroes who defeated the ''Empress of Fae'' in one of the more recent sets, gameplay wise.
*** To clarify further: the player's role is that of a Planeswalker, one of the most powerful kinds of beings in existence. The starting life total is sufficient to survive multiple attacks from [[KrakenAndLeviathan Leviathans, Kraken]], or [[InstantAwesomeJustAddDragons Ancient Dragons]]. Marit Lage will kill you in ''[[OneHitKill one hit]]''.

**** Now that the whole set has been revealed and released, there are THREE Mythic Rare Legendary Eldrazi: Kozilek, Emrakul, and Ulamog. These can't be killed permanently unless you exile them, since as soon as they hit your graveyard from anywhere, you shuffle your entire graveyard into your deck. There are six more non-Legendary Eldrazi, the smallest of which is a 7/7 and is COMMON. Of these six, 2 are common, 2 are uncommon, and 2 are rare. All of them have the Annihilator ability. Plus, there are several cards that create Eldrazi Spawn (small creatures that can be sacrificed for mana to help cast the big guys). And there are four non-creature colorless Eldrazi spells with considerable power. Notably, the mythic rare ''All is Dust'' [[KillEmAll destroys everything that has a color]] and the rare ''Eldrazi Conscription'' [[OneWingedAngel turns any creature into an extremely powerful Eldrazi]].
** Of course, there was the original [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=2093 Cosmic Horror]] if you go WAAAAAY back to the ''Legends'' expansion. The art says it all.

* ''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 NeonGenesisEvangelion of all things (what with the gigantic biological weapons called Engels that pilots mentally sync to and ride in their spines).

* The ''Gumshoe System'' has openly embraced the concept for its first settings - there is, of course, ''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 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.

** There is [[http://www.bogleech.com/mortasheen/hestermoan.htm Hestermoan]], a horrible Nuckleavee-esque monstrosity created "as an instrument of genocide against an entire civilization, and so effective that their very name remains unrecoverable". It is basically every variant of PlagueMaster rolled into one horrible monstrosity, including a HatePlague to boot.

** 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 even 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 an entire 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 interdiemensional 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 pretty much 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]].
*** And don't forget 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]]. Keep in mind the same people who banned this ''created'' the Destroyers, so something that scares [[NightmareFetishist them]] must be ''really'' bad.

** In addition to CthulhuMythos beings, several CanonForeigner were originate from this game. Examples including ''Arwassa'', ''Baoht Z'uqqa-Mogg'' and group of lesser Outer Gods.

* The Greater Titans of ''{{Scion}}'' are beyond mortal ken. They're beyond ''divine'' ken. They are so divorced from reality [[LogicBomb (despite being incarations 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 Hundan is to have a God become the Void, the living embodiment of all things chaotic...and then jump in.

* Naturally, Chaosium's ''TheCallOfCthulhu'' 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.

** Aboleths are too arrogant to worship anything, but they ''respect'' beings they call the Five Elder Evils. These are [[{{Expy}} thematically based on]] 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.]]

** 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 ''{{Ghostbusters}} 2''.)

* ''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 HPLovecraft with NeonGenesisEvangelion of all things (what with the gigantic biological weapons called Engels that pilots mentally sync to and ride in their spines).

*** And now there's spinoff game ''Mansions of Madness'', which is contained in a compact VideoGame/HauntedHouse format.

*** And now there's spinoff game ''Mansions of Madness'', which is contained in a compact HauntedHouse format.

* In WhiteWolf's ''TabletopGame/OldWorldOfDarkness'', Cosmic Horror 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. Included in this list are the various unearthly patrons of the Nephandi from ''TabletopGame/MageTheAscension'', the Fomorians from ''TabletopGame/ChangelingTheDreaming'', the Neverborn Malfeans from ''TabletopGame/WraithTheOblivion'' (and Grandmother from ''TabletopGame/{{Orpheus}}''), the Wyrm from ''{{Werewolf The Apocalypse}}'', and the Earthbound from ''TabletopGame/DemonTheFallen''. ''TabletopGame/VampireTheMasquerade'' has a lot less of this...although the Tzimisce and Gangrel antediluvians now ''resemble'' these, they started out human.

* ''{{Warhammer 40000}}'' has the Chaos Gods and their Daemons who reside in [[TheLegionsOfHell The]] [[HyperspaceIsAScaryPlace Warp]].

* In WhiteWolf's ''TabletopGame/OldWorldOfDarkness'', Cosmic Horror 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. Included in this list are the various unearthly patrons of the Nephandi from ''TabletopGame/MageTheAscension'', the Fomorians from ''TabletopGame/ChangelingTheDreaming'', the Neverborn Malfeans from ''TabletopGame/WraithTheOblivion'' (and Grandmother from ''TabletopGame/{{Orpheus}}''), and the Earthbound from ''TabletopGame/DemonTheFallen''. ''TabletopGame/VampireTheMasquerade'' has a lot less of this...although the Tzimisce and Gangrel antediluvians now ''resemble'' these, they started out human.

*** It's not so much that they are arrogant; they are just older than pretty much all of the modern day Gods and have seen how they came to power. They pretty much view them as young upstarts who have no business messing with them or demanding worship from creatures far older than they are.

** 3.5 Edition also included the Alienist class. The class features made all your Summoning spells summon creatures from the aforementioned Far Realm, which took the forms of creatures you could normally summon, but took on a template that gave them more hit points, resistances, tentacles, or other deformities and the ability to shift into their "true(r) form", which scared everything like crazy. Further, your familiar became one of these creatures. Basically, you're calling tiny C'thuloid monsters. In addition to that, the caster who takes the class eventually starts ''becoming'' like one of these creatures, goes more than a little insane, and (with the timeless body class feature) is taken to the Far Realms by the unspeakable Eldritch Horrors when they would normally die of old age, specifically ''never seen again'' by people on the prime material plane. If you manage to reach the maximum level, you can cheat dying of age altogether, gain the "Outsider" trait, and become a HumanoidAbomination. Your character grows a tentacle or two at this point.

* {{Greyhawk}} has a few of these as well:
** The most horrifying example is 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 also evolved to become a more general Abomination for the whole D&D cosmology.
** Another example is the Elder Elemental God, a bizarre entity that, from what little we see of it, is all tentacles, eyes, and sluglike bodies. Worshipped by some particularly depraved drow, some people think that the god is, in fact, another form of Dread Tharizdun, although canon remains unclear on the issue.
** 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 GaryGygax in the original 1983 Greyhawk boxed set.

** Third: The Qlippoth are basically Obyrith with the {{serial numbers filed off}} (or rather [[OlderThanTheyThink the reverse]]; see the Obyrith entry above), and cosmology-wise, the Abyss is basically a cancerous sore that's wrapped itself around reality. And the qlippoth may just originate from whatever is beyond it...

* Naturally, Chaosium's ''{{The Call of Cthulhu}}'' 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.

** ''{{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.

** The [[FairFolk True Fae]] of ''TabletopGame/ChangelingTheLost'' deserve a mention. Now, they're more recognizable than their stablemates above, capable of great {{pride}}, vanity, and twisted creativity, but they are ultimately alien, incredibly powerful, and terrifying beings with [[EvilCannotComprehendGood no concept of empathy, kindness, or selflessness]], capable of rending souls and striking pacts with aspects of reality itself, and within their [[RealityIsOutToLunch home dimension]], they are capable of [[RealityWarper just about anything]] and can twist their kidnapped human subjects to meet their needs. That they happen to have inspired {{fairy tales}} perhaps only makes them ''more'' frightening. And do you wanna know how they're born? [[spoiler: [[AndThenJohnWasAZombie No. No, you don't.]]]]

*** 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.

**** Now that the whole set has been revealed and released, there are THREE Mythic Rare Legendary Eldrazi: Kozilek, Emrakul, and Ulamog. These can't be killed permanently unless you exile them, since as soon as they hit your graveyard from anywhere, you shuffle your entire graveyard into your deck. There are six more non-Legendary Eldrazi, the smallest of which is a 7/7 and is COMMON. Of these six, 2 are common, 2 are uncommon, and 2 are rare. All of them have the Annihilator ability. Plus, there are several cards that create Eldrazi Spawn (small creatures that can be sacrificed for mana to help cast the big guys). And there are four non-creature colorless Eldrazi spells with considerable power. Notably, the mythic rare ''All is Dust'' [[KillEmAll destroys everything that has a color]] and the rare ''Eldrazi Conscription'' [[OneWingedAngel turns any creature into an extremely powerful Eldrazi]].

* ''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.]]

* 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 an entire civilization, and so effective that their very name remains unrecoverable". It is basically every variant of PlagueMaster rolled into one horrible monstrosity, including a HatePlague to boot.

** 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 literally created the Nine Hells when the Gods threw him into them.

*** To make matters worse, the third edition gave us Mind Flayers of Thoon, illithids seriously twisted by a trip to the Far Realm (which, itself, is a breeding ground for {{Eldritch Abomination}}s) who worship something known as Thoon. Their numbers include various constructs, Thoon Disciples, Shadow Flayers (mind flayers that can turn invisible), Madcrafters of Thoon (sluglike monsters that can spawn constructs), Thoon Infiltrators (former slaves infected by a Far Realm parasite that can imitate regular beings and create thralls), and Thoon Thralls (slaves that can ''blow themselves up''....really, these guys are legit).
*** Illithids aren't even naturally humanoid - they reproduce by [[TheVirus infesting]] humanoids with their larvae, which then take over and mutate the victim into a new mind flayer. Occasionally they manage to infest nonhumanoid creatures, such as dragons. And larvae that survive long enough without being implanted eventually become neothelids, gigantic tentacled worm-things with massive PsychicPowers.

*** While some Obyrith subspecies and especially demon lords have been present in the game for a very long time, the ''concept'' proper is relatively recent, and ironically not from any WizardsOfTheCoast product; the third-party supplement ''Armies of the Abyss'' by Green Ronin ([[OlderThanTheyThink which came out a few years prior to any first-party mention of obyriths]]) introduced the Qlippoth, inherently corrupt beings of Chaos and the original inhabitants of the Abyss, who created the first demons as slaves and playthings, but were brought low by a devastating war against Order, followed by conquest and occupation by the Eladrin ([[ChaoticGood celestial incarnations of Chaos]]), and a rebellion of their now more numerous demon slaves. This should sound more than a little familiar to those who know about the 3.5 backstory to the obyriths.

** The 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, as well as the Dream Larvae, who transform into something so scary that it can kill you with fear instantly the first time you look at it.
*** Also in the Epic Level Handbook are the pseudonatural creatures. Horrifying, tentacled, soul draining creatures from the aforementioned Far Realms the lesser of which can take on greater demons such as balors. Did I mention they're ridiculously resistant to spells? If you come across a paragon (paragon creatures are the perfect forms of a given creature) pseudonatural creature suicide is your best bet.
**** In fact, almost a third of all the monsters in the Epic Level handbook are eldritch abominations; visibly the authors felt that there isn't much else that can challenge you when you're powerful enough kill elder dragons and demigods.
** Then There's 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. Though the Far Realm suggests that it contains creatures possibly just as large or maybe even larger, leading this troper to believe 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.

** Aboleths are too arrogant to worship anything, but they ''respect'' beings they call the Five Elder Evils. These are [[{{Expy}} thematically based on]] 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.]]
*** It's not so much that they are arrogant, they are just older than pretty much all of the modern day Gods and have seen how they came to power. They pretty much view them as young upstarts who have no business messing with them or demanding worship from creatures far older then they are.

*** For some reason, though, 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 the 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, and 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 an entire continent, and would really like to take over the rest...
*** Don't forget the Daelkyr's unique minions and mutants. As well as the 'standard' Dolgrim, Dolgaunt and Dolgarr, Dragon Magazine also gives them Akleu, Dolgrue, Kyra, Opabinia, Xenostelid and Xorbeast, each of which is its own flavor of ghastly.
** One of the last 3.5 books Wizards released is called "Elder Evils", which features a guide of how to create your ''own'' CosmicHorror, 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 ''[[ExactlyWhatItSaysOnTheTin actual title]]''); and of course, [[AlienInvasion the Hulks of Zoretha]].

**** Atropus is a GeniusLoci, so you kill his aspect. The Leviathan wraps around the world, and all you can do is defeat minor aspects of it and put the thing back to sleep. Pandorym is probably the toughest being in the cosmos, so powerful that its stats (the strongest monster in the book) is only a fragment of its consciousness. Stats are not given for its fully released mind because it would be too much for the party, and when it unites with its body it's stronger than ''all the gods combined.'' You fight Ragnorra while she's regenerating from her crash-landing on the planet. Sertrous is fought after you force him to manifest in a weaker-than-normal form. Zargon has some very powerful abilities that only affect gods. Father Llymic, the Hulks of Zoretha, and Kyuss are all fought at their full power.
** 3.5 Edition also included the Alienist class. The class features made all your Summoning spells summon creatures from the aforementioned Far Realm, which took the forms of creatures you could normally summon, but took on a template that gave them more hit points, resistances, tentacles or other deformities, and the ability to shift into their "true(r) form" which scared everything like crazy. Further, your familiar became one of these creatures. Basically, you're calling tiny C'thuloid monsters. In addition to that, the caster who takes the class eventually starts ''becoming'' like one of these creatures, goes more then a little insane, and (with the timeless body class feature) is taken to the Far Realms by the unspeakable Eldritch Horrors when they would normally die of old age, specifically ''never seen again'' by people on the prime material plane. If you manage to reach the maximum level, you can cheat dying of age altogether, gain the "Outsider" trait and become a HumanoidAbomination. Your character grows a tentacle or two at this point.

*** 4E also has the Primordials -- a primeval race of elementals who ''created the universe'', and are powerful enough to ''destroy gods''. They would like nothing more then to [[TheEndOfTheWorldAsWeKnowIt destroy said creation]], since as their nature 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.

*** Also 4E gives Warlocks the Star Pact power source, which basically 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.

*** [[DarkIsNotEvil And at least one of those stars is good]]. While featured in a Dragon article, Ulban the Messenger is a mostly benevolent comet god who wants to change the future-thus averting TheEndOfTheWorldAsWeKnowIt, but his Star Spawn was featured in the Monster Manual Three, and oh looky, [[OhCrap it's evil aligned]].

*** The Dark Powers, the force(s) that created Ravenloft itself, could also apply, since their actual nature, methods and motives are entirely unfathomable. As well, the Nightmare Court could qualify.

** Also the Gibbering Mouther (and its 4E relatives, the Gibbering Abomination and the Gibbering Orb). The name alone is obviously inspired by Lovecraft.
** The First Edition was no stranger to Eldritch Abominations as well. 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.
* The ForgottenRealms has three Elder Evils. Ityak-Ortheel the Elf-Eater was created when the blood of the orc god Gruumsh and the elven god Corellon Larethian merged. Its appearance is Lovecraftian-inspired (a massive body supported by three legs, tentacles everywhere) It lives in between the planes and is occasionally released by mad cultists (mostly of Malar) to, well, eat elves. And anything else in its way, of course, but it takes pleasure in destroying elven towns and cities and slowly devours them over hundreds of years. The second is Kezef the Chaos Hound, who appears as a massive, skinless hunting dog, its coat covered in maggots. It hunts for the Faithful, those who worship a god, and kills them, and then the maggots swarm over the body before returning to Kezef. The soul of the person slain is utterly destroyed, and not even the gods can bring them back. It also [[DoesThisRemindYouOfAnything bit the hand off Tyr when the gods were trying to chain Kezef down]]. The third is Dendar the Night Serpent, a serpent several hundred feet long that came into being when the first creatures had a nightmare. It feeds on (and causes) nightmares of every sentient being in the world. As far as Eldritch Abominations go, Dendar serves a somewhat useful purpose: if she wasn't around, people would remember every nightmare they've had in exact, excruciating detail, never wanting to sleep again, for fear of adding to their terror.

** Another example is the Elder Elemental God, a bizarre entity that, from what little we see of it, is all tentacles, eyes and sluglike bodies. Worshipped by some particularly depraved drow, some people think that the god is in fact another form of Dread Tharizdun, although canon remains unclear on the issue.
** 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 GaryGygax in the original 1983 Greyhawk boxed set.
* The [[PsychicPowers psionic]] Slarecians of the third-party (by a WhiteWolf subsidiary, unsurprisingly) ''ScarredLands'' setting. They're revealed to originally have been beings of pure thought, who were trapped in the world as it was forming, and now they want out. They've decided the only way to do that is to completely destroy the world. The guide book detailing them goes into details of their various experiments during their time on the world Scarn, which, befitting their origins, are pretty damn weird.
** To a lesser extent, the Titans, the original rulers of Scarn. While they usually appear humanoid, and can easily interact with mortals without driving them insane, they're also powerful to the point of not having statistics, they usually see mortals as irrelevant, and their mindsets are incomprehensible.
* The {{Pathfinder}} system, being effectively D&D 3.75, has of course included those in its base setting, to the point of obvious AuthorAppeal. The Aboleths have an extensive undersea/underground empire [[spoiler:responsible for the rise and fall of that world's {{Atlantis}} stand-in]], and two of the basic pantheon's gods fit pretty well: Rovagug the Rough Beast, a ravenous, slavering monster from beyond whose reason for being is destroying the world, and who had to be stopped by all the other gods working together to [[SealedEvilInACan imprison him inside the Earth]] (many dying in the struggle), and who periodically disgorges horrid spawn to devastate the surface (like [[{{Kaiju}} the Tarrasque]]); and Zon-Kuthon the Midnight Lord, whose jealousy towards his half-sister drove him to a self-imposed exile in remote corners of the cosmos, from which he came back changed into a thing of darkness, pain and loss. Both tend to attract insane cultists (or to drive cultists insane, depending).
** ItGetsWorse, on several fronts. First: In this setting, Asmodeus is a reworked version of the above-mentioned backstory, only moreso: he is literally one of the two creator-beings of TheMultiverse, and his wounds are from a fight with the other, good-aligned creator-being, [[DevilButNoGod who was killed in the battle]].
** Second: Kytons, a formerly unremarkable race of fiends whose main characteristic was looking like people wrapped in chains, have become {{expy}}s of [[Film/{{Hellraiser}} the Cenobites]] (see film and litterature sections), and the more powerful types, while still chain-covered, look like huge, misshapen and lumpy modern art statues made from alien flesh (it's implied that the lesser humanoid Kytons are actually [[{{Squick}} the product of breeding programs with mortals]]).

** Fourth: Not only is there a Far Realms equivalent, called the Dark Tapestry, but it isn't very far, relatively speaking- it's actually ''The Void Between The Stars'', and to top it off, [[OhCrap it's the domain of literally Lovecraftian entities, Azathoth and Yog-Sothoth included]].
** Fifth: And of course, the deepest parts of [[BeneathTheEarth the Night Below]] are filled with gibbering, unsane things, among them [[CthulhuMythos Gugs]], the aforementioned Aboleths and Neothelids (the latter who explicitely worship the Lovecraftian entities of the Dark Tapestry), the [[PuppeteerParasite Intellect Devourers]] (whose constant, horrific abuse of their [[AndIMustScream still-aware hosts]] just for [[SenseFreak sick]] [[ForTheEvulz kicks]] place them in CompleteMonster territory) and [[HumanoidAbomination the Urdefan]], an artificial semi-vampiric race created by the OmnicidalManiac [[NeutralEvil Daemons]] to carry on their KillEmAll agenda on the mortal plane. Fortunately, all those things are [[EvilVersusEvil locked in constant conflict with each other and the other dark forces of the underground]].
** Sixth, well, apart from Gugs, plenty other Mythos creatures found their way to the setting, such as the [[BlobMonster Shoggoths]], [[ClockRoaches Hounds of Tindalos]] and [[HumanoidAbomination Denizens of Leng]]; in fact, [[EldritchLocation Leng]] is AnotherDimension that has infrequent bleedovers with Golarion, [[RealityIsOutToLunch with obvious results]].

** There's also a board game based on Call of Cthulhu by FantasyFlight called ''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 Old 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.]]")

* In WhiteWolf's ''TabletopGame/OldWorldOfDarkness'', Cosmic Horror 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. Included in this list are the various unearthly patrons of the Nephandi from ''TabletopGame/MageTheAscension'', the Fomorians from ''TabletopGame/ChangelingTheDreaming'', the Neverborn Malfeans from ''TabletopGame/WraithTheOblivion'' (and Grandmother from ''TabletopGame/{{Orpheus}}''), and the Earthbound from ''TabletopGame/DemonTheFallen''. ''TabletopGame/VampireTheMasquerade'' has a lot less of this... although the Tzimisce and Gangrel antediluvians now ''resemble'' these, they started out human.

*** 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...?

** 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. Said Supernal beings include the [[GodInHumanForm Ochema]], avatars of the [[BigBad Exarchs]] in ''Seers Of The Throne''. [[HumanoidAbomination Sure, they look]] [[{{Pride}} (and act)]] [[HumanoidAbomination like people]], [[StarfishAliens but look at them with Mage Sight]]... Unlike many examples, this is actually because they're ''less'' corrupted than everything else: [[CrapsackWorld The Fallen World]] simply [[DivideByZero can't handle]] [[{{Heaven}} Supernal]] beings like them... Although they stay significantly longer than and don't cause unintentional damage like Abyssal creatures, since they're ''supposed'' to be a part of the natural order of reality.
** In addition to mentioning the above Chthonians, ''TabletopGame/GeistTheSinEaters'' features Kerberoi -- wholly alien in mindset, bizarre in appearance, and nearly unstoppable, they exist solely to enforce the Old Laws of the Dead Domains. Geists can also border on this -- they're universally completely or near-completely alien in mindset, and varying degrees of bizarre in appearance.\\

** The [[FairFolk True Fae]] of ''TabletopGame/ChangelingTheLost'' deserve a mention. Now, they're more recognizable than their stablemates above, capable of great {{pride}}, vanity and twisted creativity, but they are ultimately alien, incredibly powerful and terrifying beings with [[EvilCannotComprehendGood no concept of empathy, kindness or selflessness]], capable of rending souls and striking pacts with aspects of reality itself, and within their [[RealityIsOutToLunch home dimension]] they are capable of [[RealityWarper just about anything]], and can twist their kidnapped human subjects to meet their needs. That they happen to have inspired {{fairy tales}} perhaps only makes them ''more'' frightening. And do you wanna know how they're born? [[spoiler: [[AndThenJohnWasAZombie No. No, you don't.]]]]

*** 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]][[hottip:*: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.]]. Which a Green Sun Prince can learn. Which means that ''[[TranshumanAliens every Green Sun Prince is actually an infant Primordial]]''.

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 Hundan is to have a God become the Void, the living embodiment of all things chaotic... and then jump in.

** While the Tyranids may seem more like a HordeOfAlienLocusts, the utterly alien nature of said HiveMind and the metaphysical effects of a Hive Fleet's presence (the Shadow in the Warp, which screws with communication, sensors and navigation and causes insanity in psychically sensitive beings) is rather telling. And at one point it was hinted that they were running from [[AlwaysABiggerFish something even worse]].
** 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.

** For those who don't play [=MtG=], a brief explanation: The deck, generally consisting of 60 cards, represents the player's spell reserve and memory remaining. So, effectively, everytime the Nemesis of Reason even ''looks'' at you funny, you ''lose one sixth of your mind''. No questions. And Marit Lage? She is 20 times as strong and resistant as one of the heroes who defeated the ''Empress of Fae'' in one of the more recent sets, gameplay wise.
*** To clarify further: The player's role is that of a Planeswalker, one of the most powerful kinds of beings in existence. The starting life total is sufficient to survive multiple attacks from [[KrakenAndLeviathan Leviathans, Kraken]] or [[InstantAwesomeJustAddDragons Ancient Dragons]]. Marit Lage will kill you in ''[[OneHitKill one hit]]''.

**** Now that the whole set has been revealed and released, there are THREE Mythic Rare Legendary Eldrazi: Kozilek, Emrakul and Ulamog. These can't be killed permanently unless you exile them since as soon as they hit your graveyard from anywhere, you shuffle your entire graveyard into your deck. There are six more non-Legendary Eldrazi, the smallest of which is a 7/7 and is COMMON. Of these six, 2 are common, 2 are uncommon, and 2 are rare. All of them have the Annihilator ability. Plus there are several cards that create Eldrazi Spawn (small creatures that can be sacrificed for mana to help cast the big guys). And there are four non-creature colorless Eldrazi spells with considerable power. Notably, the mythic rare ''All is Dust'' [[KillEmAll destroys everything that has a color]] and the rare ''Eldrazi Conscription'' [[OneWingedAngel turns any creature into an extremely powerful Eldrazi]].

* The Lords of Cthul from ''{{Monsterpocalypse}}'' are the Cthulhu-esque, Godzilla-sized avatars of powerful extradimensional monsters... who get [[DidYouJustPunchOutCthulhu bodyslammed]] regularly.

* ''{{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 diffetent 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 ''WarAgainstTheChtorr'') 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.
* 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).
* While [[HumansAreCthulhu our nature]] in {{Kult}} allow us to kick most super beings with ease once awakened, the Forgotten Gods are different stories. These beings represent principles incomprehensible to humanity and powerful enough that they do not even care about the plans of the [[{{God}} Demiurge]] or [[{{Satan}} Astaroth]].

** 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]].
* The ''{{Yu-Gi-Oh}}!'' 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 size 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.
** 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.

* ''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.

* [[{{Precursors}} The Ancients]] in ''{{Traveller}}''. [[spoiler:Especially Grandfather, who uplifted the rest, and exterminated them by himself after [[YouHaveOutlivedYourUsefulness they outlived their usefulness]].]]
* 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; [[ItGotWorse 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.]]
* 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.]]
* 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.
* ''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=].
* The ''Gumshoe System'' has openly embraced the concept for its first settings- there is of course ''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 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 seriously NightmareFuel.
* 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]].
* Well, though the RPG of {{Mortasheen}} isn't out yet, there are three creatures in the setting so powerful they might as well be some of these. Called [[NamesToRunAwayFromReallyFast The Destroyers]], these unfathomably powerful weapons are as follows.

** 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 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 even use victims as PeoplePuppets. And also, [[FromASingleCell even a single blood cell of it's 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 an entire 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 interdiemensional television "signal"]] [[TouchedByVorlons implied to have bounced off of]] [[EldritchAbomination Eldritch Abominations]], [[http://www.bogleech.com/mortasheen/hobkin.htm a thing that's 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 pretty much the embodiment of]] NaughtyTentacles, 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]].
*** And don't forget 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 is 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]]. Keep in mind the same people who banned this ''created'' the Destroyers, so something that scares [[NightmareFetishist them]] must be ''really'' bad.

*** Autochthon, a living non-Yozi Primordial, is a giant hollow machine-deity approximately the size of a planet, mostly made of steampuck (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 to 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.

*** 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. Did we also mention that once the Exaltation shard becomes redundant, it is released to be implanted in another Infernal...?

*** And don't forget 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 is became a PhysicalGod with control over its smaller brethren-all of which serve as AmplifierArtifacts 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]]. Keep in mind the same people who banned this ''created'' the Destroyers, so something that scares [[NightmareFetishist them]] must be ''really'' bad.

*** 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 ''literally'' [[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 why 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...?

* ''{{Warhammer 40000}}'' has the Chaos Gods and their Daemons who reside in [[HyperspaceIsAScaryPlace The]] [[TheLegionsOfHell Warp]].

* ''{{Warhammer 40000}}'': The Enslavers, who at first take on almost comprehensible forms of cyclopean octopi and swim in the warp currents. Seem kind of cute until you realize that even the hiveminded Tyranids and other creatures of the warp like Daemons have trouble with them.

** The [[FairFolk True Fae]] of ''TabletopGame/ChangelingTheLost'' deserve a mention. Now, they're more recognizable than their stablemates above, capable of great {{pride}}, vanity and twisted creativity, but they are ultimately alien, incredibly powerful and terrifying beings with [[EvilCannotComprehendGood no concept of empathy, kindness or selflessness]], capable of rending souls and striking pacts with aspects of reality itself, and within their [[RealityIsOutToLunch home dimension]] they are capable of [[RealityWarper just about anything]], and can twist their kidnapped human subjects to meet their needs. That they happen to have inspired {{fairy tales}} perhaps only makes them ''more'' frightening. [[HighOctaneNightmareFuel And do you wanna know how they're born?]] [[spoiler: [[AndThenJohnWasAZombie No. No, you don't.]]]]

* The ''Gumshoe System'' has openly embraced the concept for its first settings- there is of course ''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 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 seriously HighOctaneNightmareFuel.

** There is [[http://www.bogleech.com/mortasheen/hestermoan.htm Hestermoan]], a horrible Nuckleavee-esque monstrosity created [[HighOctaneNightmareFuel "as an instrument of genocide against an entire civilization, and so effective that their very name remains unrecoverable"]]. It is basically every variant of PlagueMaster rolled into one horrible monstrosity, including a HatePlague to boot.

** 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 even use victims as PeoplePuppets. And also, [[FromASingleCell even a single blood cell of it's can multiply inside other creatures]] [[HighOctaneNightmareFuel and consume them from the inside-out]].

** From the same [[BlatantLies cheery]] universe we have the C'Tan - one of whom is responsible for all mortal creatures (except orks) ''fearing death'' - and arguably the Tyranid Hive Mind.

** Most obviously, the Chaos Gods and the gibbering hordes of daemons at their command - TheHeartless on a cosmic scale.

** Second: Kytons, a formerly unremarkable race of fiends whose main characteristic was looking like people wrapped in chains, have become {{expy}}s of [[{{Hellraiser}} the Cenobites]] (see film and litterature sections), and the more powerful types, while still chain-covered, look like huge, misshapen and lumpy modern art statues made from alien flesh (it's implied that the lesser humanoid Kytons are actually [[{{Squick}} the product of breeding programs with mortals]]).
