History Main / TranshumanAbomination

* ''VideoGame/DarkSouls'': Manus, the Father of the Abyss, was apparently a primeval human sealed deep within a grave under the earth, then the people of Oolacile DugTooDeep, and paid the price. In the time of the ''Artorias of the Abyss'' DLC, he is a a giant monkey-like monster with curved spikes lined with glowing red eyes and a massive hand lined with octopus-like suckers. On top of looking otherworldy, he resides deep within the Chasm of the Abyss and is hell-bent on corrupting the entire land, drawing further parallels to Lovecraft. He also introduces the terrifying concept that HumansAreCthulhu upon analysing the bits of lore he brings.

--> '''The Thousand:''' I wanted what you had for myself, Parker. The things I could do with it... with power like that... but what I got was ''different''. Something better. Something worse. Something that could live ''inside'', could liquefy the innards of a man and walk the Earth within his hollow shell. Something that could watch. And wait. And ''fester''.

* ''ComicBook/SpiderMan'': Dr. Jonathan Ohn, a scientist working for the Kingpin, turns himself into [[ThinkingUpPortals the Spot]]--a walking portal network--after suffusing himself with Darkforce energy in ''Peter Parker, The Spectacular Spider-Man'' #98.

* ''Literature/DoctorSleep'': The [[Characters/TheShining True Knot]] used to be humans with some Shine, but after taking part in a ritual where they painfully ingested some Steam from a previous child victim of the Knot, they became LongLived, slow-aging vampiric creatures who ''look and act'' human at first, but they consume Steam extracted from Shiners to survive, and their flesh and bodies literally flicker in and out of existence as they're dying before they completely evaporate into Steam. In the novel, they distort into a monstrous form with a tusk in the mouth when feeding. The movie version places emphasis on the True Knot's inhuman nature via their body language becoming animalistic and cockroach-like when they're sufficiently agitated.

* ''Series/DoctorWho'': The [[Characters/DoctorWhoOtherSupportingCast Bad Wolf]] is a temporary one. She's the result of a human looking directly into the Time Vortex, [[spoiler:turning Rose into a PhysicalGod who has the raw power of spacetime running through her head, at the price of the full power threatening to burn her away until the Doctor removes it]].

While there are many "classical" monsters that used to be human, such as vampires, werewolves and zombies, they have some element that is recognizably human. You would not know these things had once been human if it wasn't stated in story. Sometimes, [[GoneHorriblyRight the transformation was a desired outcome]] of a person's goal to AscendToAHigherPlaneOfExistence. Other times, [[ForcedTransformation the transformation was involuntary]], caused by [[TheCorruption some eldritch contagion]] ([[AndIMustScream future sapience is not necessary]]). If the transformation causes them to turn evil (or were already evil while still human), then there may be some TranshumanTreachery involved.

* ''Film/FromBeyond'': Dr. Pretorius is devoured by an EldritchAbomination from an alternate dimension, somehow converting him into one of them. He keeps his mind intact, which proves unfortunate since Pretorius is a perverted monster now free to act on his every whim.

* ''WesternAnimation/WhatIf2021'': In "[[Recap/WhatIfS1E4WhatIfDoctorStrangeLostHisHeartInsteadOfHisHands What If... Doctor Strange Lost His Heart Instead of His Hands?]]", Supreme absorbs countless mystical, demonic, and otherwise supernatural entities into himself in order to gain the power to save Christine -- including a few tentacles belonging to an EldritchAbomination implied to be Shuma-Gorath. [[spoiler:The end result is that when he uses his full power he transforms into a vaguely humanoid entity with tentacles, fangs, and multiple glowing eyes... but even this power isn't enough, and he ends up being the SoleSurvivor when his actions cause his universe to melt and implode.]]

* ''Franchise/BlazBlue'': There are two noticeable examples in the series. Circumstances are different but at its core, it's the same.

* ''Manga/{{Berserk}}'': The [[OurDemonsAreDifferent Apostles]] are [[WasOnceAMan formerly human]] beings who made a DealWithTheDevil with the Godhand, they are capable of switching between their [[HumanoidAbomination relatively human]] forms and their [[OneWingedAngel Apostle form]]. Their Apostle form [[RuleOfSymbolism represents the forms of their souls within the Astral realm]] and bring it forth into the physical realm. However, despite their often unnatural and hideous forms, they are nowhere as reality-breaking as the Godhand, to which they are relatively just powerful physical monsters. That said, Emperor Ganishka does qualify when [[spoiler:he reincarnates himself into a tentacled giant who resides between the physical and Astral realms, whose size dwarfs a whole city and can function as a bridge between the two realms]]. As a side-effect, he also becomes mindlessly destructive and spawns innumerable lesser abominations to kill and eat everything in their path. The Godhand themselves were also formerly human, who particularly impressed the existing members of the Godhand just before the Eclipse, [[spoiler:as seen with Griffith's ascension]].
