History Main / MutagenicGoo

The goo comes in many forms -- it may be [[ILoveNuclearPower nuclear]] [[ToxicWasteCanDoAnything waste]], some form of [[FaceFullOfAlienWingWong alien bodily fluid]], mud from a [[SwampsAreEvil cursed swamp]], or contaminated water carrying TheVirus. Once mutated, sometimes the characters/monsters become RadiationImmuneMutants in relation to the mutagen, though not always, and repeated exposure can prove increasingly harmful.

* ''VideoGame/{{IMGCM}}'': [[spoiler:Tobio's RemoteBody Omnis is created by a strange black liquid that transforms magical girls into stronger forms called [[DarkIsNotEvil "Beast Forms"]]. [[PowerUpFullColorChange Their bodies (except for their eyes) turn black and white]] and their magical weapons become black and crystallized, causing them to somewhat look like demons. But they aren't corrupted into demons; they're still able to think, fight, and act like normal humans. This AppliedPhlebotinum first appears in the climax chapters of the 2nd Arc of the main story, and the 3rd Arc will explore more about the liquid and what the Beast Forms of the 12 heroines look like, as seen in this official [[https://imgur.com/a/0fuVd8Z teaser]]. This in-game upgrade system was implemented at the end of June 2021.]]

* In ''WesternAnimation/KimPossible'', the minor villain Gill, once a camper who went swimming in a toxic lake that caused him to change into a {{fish|People}}/{{frog|Men}} mutant, is able to excrete slimey muck that is able to mutate those in contact with it after enough time.

This is any liquid/slime/sludge form of AppliedPhlebotinum that causes living creatures that touch it to somehow mutate or transform into... [[BodyHorror something else]]. Occasionally, it may need to be ingested (or injected) to take effect, but in most cases it can be easily absorbed through the victim's skin -- their own LegoGenetics will take care of the rest.

The goo comes in many forms -- it may be [[ILoveNuclearPower nuclear]] [[ToxicWasteCanDoAnything waste]], some form of [[FaceFullOfAlienWingWong alien bodily fluid]], mud from a [[SwampsAreEvil cursed swamp]], or contaminated water carrying TheVirus. Once mutated, sometimes the charaters/monsters become RadiationImmuneMutants in relation to the mutagen, though not always, and repeated exposure can prove increasingly harmful.

Common results include BodyHorror, {{Painful Transformation}}s, and {{Lovecraftian Superpower}}s. However, it's also a fairly common backstory for non-{{Squick}}y [[JustForFun/HowtoGiveACharacterSuperpowers superheroes.]]

Differs from SuperSerum in that the effects of this are usually unexpected and nearly always [[IJustWantToBeNormal unwanted]].

* In ComicBook/TheUltraverse, DirtyCop Frank Hoag is killed in an explosion that showers him in chemicals before his body is dumped in the sewers. The combination of the chemicals and the sewage cause him to transform into the monstrous Sludge.

* The "bio-fuel" from ''Film/{{District 9}}'' that [[spoiler:turns Wikus into a prawn]].
* The black goo from ''Film/{{Prometheus}}'', codenamed Chemical A0-3959X.91 – 15. It's a particularly nasty and virulent version, a bio-weapon made up of millions of small micro-organisms, and it's strongly implied that [[spoiler:[[FromASingleCell even a drop of the stuff]] would quickly turn a habitable ecosystem into a DeathWorld populated by rapidly evolving flesh-eating nasties, ravenous mutants, and nightmarish parasites]]. Sure enough, [[spoiler:over the course of the film, it mutates an indigenous earthworm into a foot-long cobra-like parasite with acid for blood, Geologist Fifield into an extremely strong, resilient and aggressive space-zombie, and a sort-of proto-xenomorph.]] In ''Film/AlienCovenant'', [[spoiler:David uses it to wipe out the ecosystem of an Engineer-colonized planet and experiments with it to create the Xenomorphs]].
* The Ooze from ''Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze'', which according to Professor Perry was [[FreakLabAccident an unknown mixture of discarded chemicals that was accidentally exposed to a series of radiative waves]].
* A squirrel in ''WesternAnimation/TheSimpsonsMovie'' was mutated in Lake Springfield after Homer dumped an overflowing silo filled with pig excrement into the lake, causing it to become highly toxic. When chased into the lake by a raccoon, the squirrel emerges as a multi-eyed squirrel mutant.
* In ''Film/TheMatrixReloaded'' and Film/TheMatrixRevolutions, Agent Smith has the ability to [[ClonebyConversion transform a person into a copy of himself]]. The transformation process involves a black substance covering the victim’s body and once the entire body is covered, converts the person into an Agent Smith clone

** The slime produced by the Wirrn in "The Ark in Space", which turns humans into Wirrn.

** In the Seventh Doctor episode "Delta and the Bannermen", even Chimeron ''baby food'' turns a regular guy/love interest into a Chimeron--which, fortunately, was the outcome besotted young Billy was hoping for.

* ''TabletopGame/MagicTheGathering'' has the Phyrexian oil that kickstarted the Phyrexian invasion of Mirrodin.
** [[GeneticEngineeringIsTheNewNuke Experiment Kraj]] and the rest of the Simic Combine might also qualify, with their [[AppliedPhlebotinum cytoplasts]].

* Various substances in ''Toys/{{Bionicle}}'' induce this effect. Energized Protodermis is either this or an AcidPool, depending on whether you are destined to transform or not, and Pit Mutagen will induce mutations that vary from species to species (on the Barraki, it had the effect of transforming them into FishPeople, whereas the Makuta Mistika experienced ShapeshifterModeLock upon exposure). The Piraka lost most of their bodies and became snakelike creatures, Brutaka was only subtly effected by it, and the Mahri Nui Matoran actually experienced a positive change (temporary exposure undid many of Karzahni's modifications). While not "goo," Roodaka's Rhotuka Spinner, Hordika Venom, and Miserix's mask of mutation can also induce transformations.

* In ''VideoGame/{{Geneforge}}'', the content of canisters and [[spoiler:[[TitleDrop Geneforges]]]] are most often blue or green, other times ochre or magenta, but always gooey and a catalyst for mutation.

* In ''VideoGame/SouthParkTheStickOfTruth'', the alien goo turns anyone who touches it into a Nazi zombie, complete with the voice of UsefulNotes/AdolfHitler. Clyde however thinks that it's Taco Bell Green Sauce and refuses to be convinced otherwise.

* [[Website/{{Fenspace}} Handwavium]] has this effect on living tissue; being turned into a CatGirl is one of the ''less'' weird things it can do to you if you aren't careful.

* ''WesternAnimation/{{Futurama}}'' has a mutagenic lake in the sewers of New New York. It turns rats into flying fish-pigs, and a purple octopus living there claimed to have once been a little blonde girl named Virginia. [[RadiationImmuneMutants Sewer mutants are, of course, immune,]] and so use the lake as a punishment against offensive outsiders.
* In ''WesternAnimation/KimPossible'', minor villain Gill, once a camper who went swimming in a toxic lake that caused him to mutant into a {{Fish|Man}}/{{Frog|Man}} mutant, is able to excrete slimey muck that is able to mutate those in contact with it after enough time.
* The Ooze that transformed the Franchise/TeenageMutantNinjaTurtles from regular turtles into the awesome ninjas we all know is probably the TropeCodifier. A common threat in ''WesternAnimation/TeenageMutantNinjaTurtles1987'' was ''Retro''-Mutagen Ooze, which Shredder and other villains tried to use to turn the turtles back into their regular non-mutated selves. The general logic is that it [[LEGOGenetics hybridizes a specimen]] with the DNA of whatever organism it was previously in contact with. Generally this ended being strictly animal-human interactions, so either one ended up mutating into anthropomorphic animals. Some series depict experiments with the ooze's mutagenic effects, granting other powers along with being superhuman anthropomorphic mutants.
** ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles'' features ooze that's a bit different than usual from the franchise, as it's actually magical, and specifically turns people into {{Youkai}}. [[spoiler:The series finale [[DoingInTheWizard possibly undoes this interpretation, as the ooze is revealed to be coming from an Utrom's artifact]]]].

* The Ooze from ''Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze'', which according to Professor Perry was an unknown mixture of discarded chemicals that was accidentally exposed to a series of radiative waves.

* In ''VideoGame/SouthParkTheStickOfTruth'', the alien goo turns anyone who touches it into a Nazi zombie, complete with the voice of UsefulNotes/AdolfHitler.

* In [[http://www.sinfest.net/view.php?date=2004-09-24 this]] strip of ''Webcomic/{{Sinfest}}'', Slick bolts from a {{mutant}} creature emerging from a toxic waste pit.

* In ''Anime/KemonoFriends'', this role is accomplished by the "Sand Star", a mysterious substance that turns regular animals into the humanoid Friends. It can also change the Biomes of a given region [[spoiler:and turns inorganic matter into the antagonistic Ceruleans.]]

* One form of Phazon in the ''VideoGame/MetroidPrimeTrilogy'' is like this. Other times it appears as [[GreenRocks crystals]]. The mutations it causes appear to be due to long-term exposure to a type of radiation it emits.

* In ''VideoGame/{{Geneforge}}'', the content of canisters and [[spoiler: [[TitleDrop Geneforges]]]] are most often blue or green, other times ochre or magenta, but always gooey and a catalyst for mutation.

** In a milder example from ''VideoGame/{{Fallout 2}}'', walking through toxic waste without protective footwear will cause the player character to grow an extra toe.
* Structure Gel from ''VideoGame/{{SOMA}}'' is a black, slimy chemical that's a fantastically efficient conductor when used on machines - and also happens to have mutagenic properties that transformed the majority of the PATHOS-II staff into horrible [[OrganicTechnology biomechanical monsters.]]
* ''VideoGame/SpaceQuestVTheNextMutation'' has Primordial Soup, which was created in a bacteriological experiment gone catastrophically wrong. Infected humans become "Pukoids," who attempt to transmit TheVirus to others by vomiting on them.
* ''VideoGame/RogueStormers'' has the Goop, an oil-like, black, oozing substance that horribly mutates living beings in [[AppliedPhlebotinum addition to powering]] {{Dieselpunk}} tech.

[[folder:WebComic]]
* ''WebComic/WastedAway'' has large pools of this nasty stuff dotting the landscape. Sometimes cats like to get high off it, but falling in can do strange things - it turns Gerald and Ez into a massive creature with huge claws, and turns Radon green.
* ''WebComic/{{Wurr}}'' has the Black Touch, found throughout the crater; its effects on an entirely normal dog haven't yet been shown, but given that it can make the already-mutated hounds even more so, it likely wouldn't be pretty.

* ''VideoGame/{{Changed}}''is all about this. A cure was created to combat [[ThePlague the pale virus]], and it transforms people into anthropomorphic animals made out of the substance that transformed them.

* Energized Protodermis from ''Toys/{{Bionicle}}'' is either this or an AcidPool, depending on whether you are destined to transform or not. Also, the water in the Pit would slowly mutate beings into FishPeople, although the effect on organic creatures would be much slower and less noticeable.
