History EldritchAbomination / TableTopGames

* In the TabletopGame ''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.

* Your child character controls his or her pet EldritchAbomination (including fallen gods, an undead amalgamation of a football team that died in a bus crash and etc.) in TabletopGame/MonstersAndOtherChildishThings.

* In Glorantha (as seen in ''TabletopGame/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. In the 2018 4th ed. ''TabletopGame/RuneQuest'' bestiary, the Crimson Bat is a servant of the Red Goddess and it's in a special category of monster known collectively as "Terrors". These are unique monsters of tremendous power and their purpose is to show that there are threats well beyond what an adventuring party can handle.

* ''TabletopGame/DungeonsAndDragons'' has [[EldritchAbomination/DungeonsAndDragons its own page]]

* ''TabletopGame/{{Zweihander}}'' is the spiritual successor to ''TabletopGame/WarhammerFantasyRoleplay''. As such the game has {{Expy}} to Warhammer's 4 Chaos Gods in the Abyssal Princes who are Khorne, Tzeentch and etc. with [[NoNameGiven titles instead of names]]. Several other entities join the Abyssal Princes as part of the Chaotic pantheon, including the Black Lodge - a race of [[TheFairFolk twisted fairies]] and an eternally hungry mouth on the surface of the planet.

* The darkness in ''TabletopGame/BleakWorld'' is an unstoppable force that eats planets and turns everything on them into its dark servants. It is locked out of the Milky Way Galaxy for now, but it still manages to get its servants in from time to time so they can get it in.
** Also whatever The Caretaker of [[FateWorseThanDeath the death beyond death]] is for ghosts.
** The Caretaker is actually implied to be the Darkness itself, and is described as being "a massive field of liquid darkness, made of thousands of mouths and eyes". It presides over an EldritchLocation where ghosts go when they die; they feel eternal pain, but can never actually go insane from it.
* Hinted at in ''TabletopGame/RocketAge''. There is a psychic entity powerful enough to sense and be sensed by psychics in our solar system across the void of deep space. All we know is that it terrified the one Venusian Lizard Monkey who felt and knows that it is coming for him.

** There is a thing in the ''40K'' universe known as the "Echoing Vault". All Imperial records of it were expunged, but some details remain telling it contains bizarre xenoforms known as "The Harrowing" that in ages past destroyed thousands of worlds, broke the laws of physics by existing, drove millions of people insane by their mere proximity, and required the use of ancient, barely-understood psychic weapons to seal away. When a Chaos warband threatened to open it, a [[GodzillaThreshhold full battalion of the]] Adeptus Custodes (SuperPrototype Astartes that serve as the God-Emperor's personal PraetorianGuard; ''small squads of regular Astartes'' are capable of conquering whole planets) were deployed to stop them, [[CurbStompBattle and stop them they did]].

* ''TabletopGame/{{Warhammer}}'', ''TabletopGame/WarhammerAgeOfSigmar'' and ''TabletopGame/{{Warhammer 40000}}'' 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.

** 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. [[FromBadToWorse And even worse?]] It's heavily implied '''[[UltimateEvil something]]''' even more terrifying has been chasing them from their home galaxy all the way to the Milky Way, something that is ''still coming''.

** 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. At least the other Gods have motives that are comprehensible to mortal minds: Khorne wants blood, Nurgle loves disease, and Slaanesh is after pleasure. Good luck figuring out whatever Tzeentch is pursuing.

* The ''TabletopGame/{{Gumshoe}} System'' has openly embraced the concept for its first settings -- there is ''TabletopGame/TrailOfCthulhu'', their own take on the [[Franchise/CthulhuMythos Mythos]], but there is also the basic campaign world for ''TabletopGame/TheEsoterrorists'' and ''TabletopGame/FearItself'', 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.

* ''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).
** The Gibbering Mouther is the most well known and reviled example of horrendous Aberration type creatures hailing from the Far Realm, a BlobMonster with TooManyMouths and [[EyesDoNotBelongThere eyes in weird places]] whose constant gibbering induces BrownNote and sucks blood from its victims. Plus, some excerpts directly reference Lovecraft's own Shoggoth, of which it perfectly resembles.
*** It turns out that the Gibbering Mouther is actually the weakest type of gibbering beasts. The stronger kinds are the gibbering abomination, which looks like a more solid mouther with tentacles that also has EyeBeams, and the gibbering orb, which looks like a floating sphere of eyes and mouths that have even more EyeBeams. Although gibbering beasts seem like they are completely insane, they actually are quite intelligent and may work with other kinds of aberrations to accomplish mysterious goals.
** The Beholders are one of D&D's most iconic aberrations. Most kinds of Beholders look like floating spheres with a mouth and a huge eye and a large number smaller eyes on eye stalks, with each eye having a different power. Beholders became even stranger in fifth edition where it is retconned that beholders do not reproduce by regular means, but instead reproduce by dreaming. Having the ability to [[RealityWarper warp reality]] in their sleep, they unconsciously create new beholders based on what they dream about. This has lead to a theory that the whole world is just a beholder's dream.
** 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 [[{{Satan}} 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, ''hundreds of miles long'' serpentine creature named Ahriman who is still injured from his crash landing in Hell. He was some sort of [[TimeAbyss primordial entity who predated the Gods]] and either was thrown into Baator by the gods or crashed there after his struggle with his twin sister Jazirian (who seems to have become the god of the Couatls -- AlwaysLawfulGood winged serpents -- since then). In the latter case he fell so hard that when he hit the bottom of the seventh layer (Baator initially had seven layers), he fell ''through'' it and created the eight layer, only to fall through ''that'' as well and land on the ninth layer, where he came to a stop at the bottom of an impossibly deep canyon created by his fall.
*** While he is still injured by the fall he found a way to recover: by feasting on the souls of unbelievers he regains his power to the point where he can break free from his prison of Baator and remake the multiverse in his image. Fortunately, people who do not believe in anything are rather rare in the setting and Asmodeus can gather this energy only in trickles over the course of centuries. To both increase the number of unbeliever souls and to deceive those who would stop him Ahriman created Asmodeus to divert attention away from this fact. Everything about him and his actions, from his status as an angel, his fall, the [[ForeverWar Blood War]] and the politics of Hell are nothing but a sham designed to keep everyone occupied and freeing a lot of Asmodeus' time to be able to plot to increase the numbers of unbelievers to feed on. [[FromBadToWorse And the worst part? It's working.]]
** Before Asmodeus even landed in the Nine Hells, they were inhabited by the Ancient Baatorians. Hardly anything is known about them, since they appear to be resistant to both scrying and divine magic, and because Asmodeus has done his best to remove record of their existence from existence. They still occasionally manifest as indestructible, shapeless forms that breathe in light and breathe out darkness. Some of them even ''breathe life'' rather than light. Some say the Ancient Baatorians aren't even alive in the same way that both devils and mortals are -- they're more some kind of formless primordial entity that can only partially manifest under certain conditions and in certain places. More strangely, the realm of Baator itself seems to be involved in their generation -- nupperibo [[note]]the weakest type of devil[[/note]] will evolve into an Ancient Baatorian over a very long period of time, which is why more powerful devils destroy nupperibo when they can.
** Expanded upon in ''TabletopGame/TheGatesOfHell'' fan supplement. Asmodeus is the Prime Force of Lawful Evil, who initially was part of a circle of three beings. Once their disagreements on how to arrange the multiverse caused them to separate, Lawful Good was flung up and created Heaven, Lawful Neutral was flung sideways and became the cogs of Mechanicus, and Lawful Evil was flung down. That fall didn't create two of Hell's circles, it created all of them. The Ancient Baatorians, the Malefircareim, were formed out of his blood, each a demigod. Then, a trillion or so years later, the Overlord awoke, found his "children" to be too independent, and created an avatar to put them in place. That wasn't Asmodeus; he was named Lucifer. The final battle was Lucifer against ''nine million'' of the demigods, and it was a CurbStompBattle. He spared a few to become the Lords of Nine and other noblemen, and created a hierarchy of weaker devils, from lemures to pit fiends [[note]]some Malefircareim did flee or were spared for the Overlord's own reasons, and yes, the nupperibo, who, unlike the lemures, are born from the very ground of Hell, will eventually evolve into them -- with an intermediate stage called barregons[[/note]]. A couple trillion years later, the Overlord grew wary of gods opposing him, so he created a second avatar, Asmodeus, and [[XanatosGambit "overthrew" Lucifer, to make Hell appear less threatening]]. When a devil who aided Asmodeus, who also happened to be his wife, suspected something and wanted to know more about him... well, she was never the same after he showed her, ultimately getting killed while attempting a literal BrainBleach. Now, what is the Overlord doing with his time? He feeds upon mortal souls in order to heal his real body. How big is the body? Not hundreds of miles. It is a winged serpent ''which can fit the entire Earth on a single one of its scales''.
** The Obyrith were the demons who ruled the Abyss before the Tanar'ri; they existed [[TimeAbyss since before the dawn of time]] or at least conventional mortal life, often have incomprehensible biologies, and just glancing at one is enough to induce new phobias or temporary insanity. One of the oldest still extant, [[MotherOfAThousandYoung Pale Night]], horrifies ''reality itself'' to the point where reality hides it behind a series of ripples in existence [[AFormYouAreComfortableWith making her seem like an otherworldly woman hidden behind a series of veils]] and can ''kill'' [[BrownNote if you get a glance]] at [[YouCannotGraspTheTrueForm her true form]].
*** The 360th issue of ''Dragon'' magazine, the last of the 3.5 edition era, had an article about her most (in)famous offspring, the {{Demon Lord|s And Archdevils}} Graz'zt, including allusions to [[MultipleChoicePast many possibilities]] besides the "official" one concerning who his father was. One of those possibilities? [[Franchise/CthulhuMythos The Crawling Chaos, Nyarlathotep]].
** 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.
*** Really, several other monsters from the book qualify, such as the Neh-Thalggu brain collectors ([[ExactlyWhatItSaysOnTheTin guess what they do]]), the Uvudaaum, who are powerful enough to reign as {{Sorcerous Overlord}}s over sections of the Far Realm itself, and the epic version of the pseudonatural template, which represents creatures that are either heavily corrupted by the Far Realm's taint, or are actually attempts by the Far Realm to imitate "normal" lifeforms. Which tend to fail. Badly ([[http://vignette4.wikia.nocookie.net/sfery/images/a/a7/44260_C5_pseudonaturaltroll.jpg/revision/latest?cb=20111224000559 trolls should not look like that]]).
** 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.
*** One could argue that the Abyss, a LayeredWorld upon a LayeredWorld, is a similar kind of living EldritchLocation. Many of the levels of the Abyss are certainly alive and thinking, the 92nd layer itself being no more than a giant tentacle monster called a Draeden; however it's made clear that the Abyss as a whole, and the Demons that live within, are a single entity. It's inferred that the already infinitely deep Abyss feeds on the other dimensions around it, absorbing them into its mass; and worse yet, [[FromBadToWorse It's growing]] ''[[MoreThanInfinite even bigger]]''.
** 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.]].
*** Aboleths themselves are very strange creatures. Though they look like sea monsters, the three eyes arranged vertically tell you they are something much more alien. Their species is [[TimeAbyss older than the gods]] and all of them can remember all the way back then because they have perfect memory and receive all of their parent's memories when they are born.
*** The only thing that Aboleths are really disturbed by are the brain eating {{Cthulhumanoid}}s known as Illithids, simply because Aboleths have no idea where they came from.
*** 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]]. And their plane of origin, Xoriat, is Eberron's cosmological equivalent to the Far Realm.
*** 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''...
*** WordOfGod later clarified that this was a joke and that [[AFormYouAreComfortableWith nonhumans see them as looking similar to themselves.]]
*** 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 Forgotten Superweapon; 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 Franchise/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 D20 setting ''TabletopGame/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. They also far exceed most other monsters in sheer size; the largest are well over a quarter mile long, [[AlienGeometries at least as far as their stats are concerned]]. 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. A few other have been [[http://www.enworld.org/forum/showthread.php?268666-3-5E-Nehaschimic-Dragons unofficially published online]], and are just as weird, if not more so, than the nexus dragon.
*** On [[http://www.enworld.org/forum/forumdisplay.php?304-Eternity-Publishing-Hosted-Forum the forum which discusses possible ideas for these books]], one person suggested an adventure where a planet needs to be evacuated because it's a dragon egg about to hatch. The poster eventually made the idea into dragons[[note]]called Muhlatimic, after the Hebrew word for ''ultimate''[[/note]] which are the nerves of the AkashicRecords (the one power above God, basically). Their flavor text is about a MultiversalConqueror who has just crushed the God of another universe... and then he sees one of these dragons. It ends with him realizing that [[spoiler:the almighty artifact around which he built his empire is merely a scale said dragon lost]]. No attempts to stat the dragons have been made as of fall 2017.

* ''TabletopGame/MagicTheGathering'' has a card literally named "Cosmic Horror", which has artwork befitting an eldritch abomination. However, its power and toughness are only 7/7 and its only beneficial ability is first strike, so it can lose a cage match to beings as mundane as HumongousMecha (Colossus of Sardia, Phyrexian Dreadnought, etc), GaiasVengeance (Force of Nature, Avatar of Might, etc.), [[SeaMonster sea monsters]] (Leviathan, Polar Kraken, Marjhan...), sufficiently large reptiles (Endless Wurm, Hellkite Overlord), the [[HiveQueen Sliver Queen]] if she has [[AllYourPowersCombined the right cheerleaders backing her up]], or even just a random Chinese dude named Zhou Yu.
** There are also other, bigger horrors, abominations, nightmares, aberrations, nightmare horrors, etc., such as Devouring Strossus and Hypnox. Most of these, however, were created long after the game [[JumpTheShark jumped the shark]], and are therefore not worth mentioning.

* ''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.

* ''TabletopGame/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://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=188962 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://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=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 live outside of the universes and "feed" off of reality, leaving the worlds they enter dead and bare of life and energy, and had been [[SealedEvilInACan locked away]] six thousand years ago by a trio of planeswalkers (Ugin, Sorin Markov and Nahiri). The block culminated in the Rise of the Eldrazi after 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 resources 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]].
*** In addition to having no color, the Eldrazi in their native state also have no form. They were forced into physical form by the planeswalkers who trapped them on Zendikar so they could be fought.
*** It's been revealed in recent material that the Eldrazi creatures aren't individual monsters, but simply lesser parts of a greater Eldrazi entity in the Blind Eternities (the space between the planes). So, each of Ulamog's brood, including the one referred to itself as Ulamog, are more like organs and extremities than anything else.
*** At the end of the Oath of the Gatewatch storyline, when the entireties of Ulamog and Kozilek are pulled into Zendikar, they lose their physical forms altogether and ''become the sky'', with a dome of bone and flesh replacing the clouds and sun, as if the whole world was now inside them. AlienGeometries is in effect, too, as one character compares the effect to space warping so that the outside of Ulamog's body is now in every direction she looks at, with its "actual" body still overhead even as its limbs and appendages pointing from every direction.
*** Of the three Titans, Emrakul is the most eldritch. Ulamog and Kozilek have vaguely humanoid features (limbs, torsos, heads, etc.). Emrakul looks like a jellyfish from hell or a floating mass of rock with a tangle of arms and tentacles hanging from the bottom, as can be seen on the main page. Emrakul is also the biggest of the titans, and surprisingly, sapient.
*** The Eldritch Moon set illustrates nicely what Emrakul does with living creatures: they mutate, often merge and become extensions of her will, growing much stronger in the process. The two other titans merely eat everything and transform landscapes into wasteland.
** A backstory of Nicol Bolas mentions that the first dragons in ''Magic'' multiverse were birthed by the aptly-called Ur-Dragon. While a dragon siring more dragons is normal, the Ur-Dragon gets an eldritch point by being able to traverse the Blind Eternities willy nilly, not unlike the aforementioned Eldrazi.

** 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).

** 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 ''Gumshoe System'' has openly embraced the concept for its first settings -- there is ''Trail Of Cthulhu'', their own take on the [[Franchise/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.

** 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.

** The God-Emperor of Mankind, amazingly enough. Even though he ''looks'' human, he's actually a living violation of physics so absurdly powerful that he serves as a navigation beacon in the Warp, a chaotic dimension which is constantly shifting. In the ''Literature/HorusHeresy'' novels, it's shown that [[YouCannotGraspTheTrueForm the Emperor's appearance varies between who views him]]: for example, Lorgar saw him as a tall man with sun-kissed skin and black hair in a long ponytail, while Horus saw an old man with glowing wheels of fire for eyes, and Corax actually saw him as the latter first and then the former. Interestingly, his dedicated AntiMagic specialists see him as [[spoiler: a [[TheNondescript remarkably unremarkable man]]. It's speculated that if the Emperor ever dies then he will become a Chaos god himself, a Chaos god ''[[MindScrew of]]'' ''[[LightIsNotGood order]]''.

*** Of the three Titans, Emrakul is the most eldritch. Ulamog and Kozilek have vaguely humanoid features (limbs, torsos, heads, etc.). Emrakul looks like a jellyfish from hell or a floating mass of rock with a tangle of arms and tentacles hanging from the bottom, as can be seen on the main page. Emrakul is also the biggest of the titans.

*** 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.

** And there also is [[NamesToRunAwayFromReallyFast the Dominion of the Black]], an entire organization whose rank-and-file are apparently purpose-bred lesser abominations (such as the neh-rhalggu brain collectors, the intellect devourers, and a variety of other horrors like fleshy tree-like things that eat emotions and hideous {{Organic Spaceship}}s), who all hail from the dark recesses of the cosmos. They may be preparing an invasion of Golarion (''Pathfinder''[='=]s main setting/world), and one of their supposed leaders is... [[http://pathfinderwiki.com/wiki/Tychilarius THIS thing]]. Surprisingly enough, they don't get along with the Great Old Ones and the Outer Gods; in point of fact, they detest them and their followers and [[EvilVersusEvil the two groups are locked in bitter rivalry]].

** The literally biggest one (so far) would be Aucturn, an entire living planet roughly ''twice'' the size of the Earth-like Golarion with rubbery soil and vast seas and rivers of black ooze beneath. Populated by... pretty much everything mentioned above. Features of the planet are literally rotting temples of flesh-stone blocks, citadels of insane cultists, a valley full of cloying mists that make the inhabitants impregnate any outsiders(as opposed to eating or sacrificing them elsewhere) and a massive mound that contains Aucturn's gestating offspring. Oh, did we mention this horrible, horrible planet is '''''pregnant?'''''

** And there also is [[NamesToRunAwayFromReallyFast the Dominion of the Black]], an entire organization whose rank-and-file are apparently purpose-bred lesser abominations (a less-powerful version of the Neh-Thalggu brain collectors among them), who also hail from the dark recesses of the cosmos and may be linked to the Great Old Ones and the Outer Gods; they may be preparing an invasion of Golarion (''Pathfinder''[='=]s main setting/world), and one of their supposed leaders is... [[http://pathfinderwiki.com/wiki/Tychilarius THIS thing]].
** The [[BeneathTheEarth Vaults of Orv]] hold their fair share of abominations, such as the neothelids and their minions (giant [[PsychicPowers psionic]] worm-things who worship the aforementioned Dark Tapestry's Franchise/CthulhuMythos), the [[PuppeteerParasite intellect devourers]] and the ghorazaghs, also known as Gore Weavers because they use the blood of their victims as building materials for their bizarre hive cities. Most of the creatures living here worship either the Great Old Ones, the Dominion of the Black, Rovagug or some combination thereof.
