* ''TabletopGame/TechInfantry'', as a spinoff of the ''TabletopGame/OldWorldOfDarkness'' (see above under TabletopGames), also has the Tszimisce clan, but their Viscissitude abilities are ''weaponized'' for soldiers of the Black Hand. These abilities are also [[RetCon retconned]] into being partial but progressive possession by the Soul Eater aliens from the planet Fieras VI, who eventually transform their victims into new Soul Eaters and completely take over their minds.\\
Amusing fact: This isn't actually a retcon as such, because the origin story of Vicissitude as given in the much-reviled supplement ''Dirty Secrets of the Black Hand'' is this, except replace "alien virus" with "spirit virus from the netherworld." That idea was retconned in revised edition, so ''Tech Infantry'' is retconning the RetCon.
* In ''TabletopGame/NewVindicators'' most of the superhumans are fairly normal looking, with the occasional ape person, or winged girl, but that can sometimes be a good thing. Even ancient Nephilim like Apocatastasis, who's freakishly tall and has twelve fingers, aren't that bad. But Bulwark actually has it fairly bad-he's a rock man, like the Thing, only played a little more straight. So no eyes, no functional nose, no sense of touch-'seeing' through vibrational senses, he's a mutant freak among mutant freaks.
* The ''Wiki/SCPFoundation'' has so very much that trying to list them all would involve recreating half the site here. Reading random articles for any length of time is bound to make your skin crawl. Virtually any SCP labelled "[[http://scp-wiki.wikidot.com/system:page-tags/tag/transfiguration#pages transfiguration]]" will involve some degree of this trope.
** [[http://scp-wiki.net/scp-149 SCP-149 ("The Blood Flies")]]. These mosquitos inject a virus that changes human cells into mosquito eggs. When the eggs hatch they fly out your mouth, nose or possibly eyes, which kills you.
** [[http://scp-wiki.net/scp-150 SCP-150 ("The Prosthetic Parasite")]]. SCP-150 infects the human body, changing the victim's limbs and torso into egg cases to hatch out its larvae.
** [[http://www.scp-wiki.net/scp-186 SCP-186 ("To End All Wars")]]. The weapons the soldiers were given did things like causing tumors to grow and forcing victims to stay alive even after half of their heads had been blown off.
** [[http://www.scp-wiki.net/scp-212 SCP-212 ("The Improver")]]. This device performs bizarre surgical procedures on its victims that leave them worse for wear. Changes have included replacing teeth with sharp blades, replacing feet with pads, and replacing hands with tentacles or crab claws.
** [[http://www.scp-wiki.net/scp-290 SCP-290 ("The Picasso Machine")]]. After a person enters SCP-290 it relocates their limbs and facial features to random parts of their body, but without affecting functionality. It also changes their internal organs, blood vessels and nerves to support the body parts' new locations.
** [[http://www.scp-wiki.net/scp-412 SCP-412 ("Mutagenic Mirror")]]. Each time a subject views themselves in the mirror they suffer progressively worse bodily changes. The changes start out with enlarged lymph nodes, a facial rash, and skin discoloration. They eventually progress to an expanded ribcage, mouth cysts that force the jaw to stay open, and problems with the immune and reproductive systems.
** [[http://www.scp-wiki.net/scp-415 SCP-415 ("The Harvested Man")]]. SCP-415 is a human being who has been physically altered so it is easy to surgically steal his organs.
** [[http://www.scp-wiki.net/scp-420 SCP-420 ("Aggressive Skin Condition")]]. Anyone drinking SCP-420-1 (the liquid inside SCP-420) will suffer six stages of progressive body changes. The changes include finger nails, toenails and skin becoming brittle and growing at an increased rate, skin cancer, skin, hair and mouths growing in random locations, and the victim's skin killing and eating other creatures.
** [[http://www.scp-wiki.net/scp-428 SCP-428 ("The Crowd")]]. All of the members of the crowd are former human beings who have had every part of their bodies other than their skin replaced with an unidentified material.
** [[http://scp-wiki.net/scp-446 SCP-446 ("Human Mannequin")]]. SCP-446 was apparently originally a human woman who was changed into the form of a mannequin by unknown means.
** [[http://www.scp-wiki.net/scp-466 SCP-466 ("Mobile Veins")]]. SCP-466 is the animated combination of the cardiovascular systems of four different people, plus the head of the original person. Originally it was the cardiovascular system of one person which somehow became independent of its original body. It obtained the additional three systems by attacking several doctors that were trying to help it after it appeared to die.
** [[http://www.scp-wiki.net/scp-478 SCP-478 ("Tooth Fairies")]]. After SCP-478 infects a human victim's mouth, teeth will begin to grow at a tremendous rate. The growth will fill the victim's palate and then spread to the rest of the digestive tract, lungs and underneath the skin.
** Probably the most prominent example of this trope, and one many people have a particular horror for, is [[http://www.scp-wiki.net/scp-610 SCP-610: "The Flesh That Hates"]]. Think [[VideoGame/DeadSpace Necromorphs]], the creature from [[Film/TheThing1982 John Carpenter's The Thing]] or the [[VideoGame/{{Prototype}} BLACKLIGHT virus]], and you have a pretty good idea. Probably NSFW.
** [[http://www.scp-wiki.net/scp-1046 SCP-1046 ("A House Without a Bedroom")]]. A man's body is spread out over an entire house in pieces.
** [[http://www.scp-wiki.net/scp-1227 SCP-1227 ("The Family Man")]]. SCP-1227 is eight human beings and a dog somehow merged together into a single scrambled creature as a result of a horrific experiment.
** [[http://www.scp-wiki.net/scp-1353 SCP-1353 ("Comforting Centipedes")]]. SCP-1353 can cut a hole in the skin (its venom is an anesthetic) and enter the human body, moving around inside of it.
** [[http://www.scp-wiki.net/scp-1407 SCP-1407 ("DJ's Headphones")]]. When SCP-1407 is placed in a human being's ears it will insert wires throughout the body, eventually creating more instances of itself.
** [[http://www.scp-wiki.net/scp-1510 SCP-1510 ("The Tarnished Legionnaire")]]. A Roman legionnaire was affected by a curse that caused his body to rot away and his mind/soul to be stored in his helmet.
** [[http://www.scp-wiki.net/scp-1707 SCP-1707 ("New Skin")]]. Having your skin removed and replaced by a colony of worms can ruin your whole day.
** [[http://www.scp-wiki.net/scp-1877 SCP-1877 ("The Guts of the Earth")]]. The intestines of three people in widely separated areas somehow became connected. The connecting intestines actually physically pass through areas in the real world such as electrical conduits, telephone receivers, water mains, sewage pipes, and subway tunnels.
** [[http://www.scp-wiki.net/scp-2051 SCP-2051 ("Stromatolite Habitat")]]. Anyone who is completely immersed in SCP-2051 (a certain cove on the coast of Australia) will undergo a transformation the next time they enter a man-made body of water (bathtub, swimming pool, reservoir etc.). They will lose all external structures (nails, teeth, hair), their bones will dissolve and their internal organs will change to skin tissue. Their brain will be split up into nerve bundles throughout the body.
** [[http://www.scp-wiki.net/scp-2102 SCP-2102 ("Got Shoggoth?")]]. SCP-2102 is a human being who underwent an experiment. Whenever he suffers any kind of wound his body starts repairing itself at a rate a quadrillion times faster than normal. This creates large amounts of extra flesh, and he keeps on growing until his body is cauterized by flame.
** [[http://www.scp-wiki.net/scp-2126 SCP-2126 ("Letter from Grandma")]]. Hair grows downward through your skin. If you like slow and painful death, you'll love this.
** [[http://www.scp-wiki.net/scp-2401 SCP-2401 ("Mary Had A Little Lamb")]]. SCP-2401 are honeybees that can enter a human body and build honeycomb-like structures inside it, turning the body into a large hive.
** [[http://www.scp-wiki.net/scp-2484 SCP-2484 ("Parasitic Mayonnaise Worms")]]. If an amount of SCP-2484 exceeding 235 grams is removed from its container, it will attempt to enter the body of the nearest vertebrate animal, by force if necessary. If any vertebrate animal eats enough SCP-2484, the eggs in SCP-2484 will hatch and grow into worms that consume the victim's body.
** [[http://www.scp-wiki.net/scp-2610 SCP-2610 ("Procreation")]]. SCP-2610-E are altered human beings produced by genetic engineering and inbreeding. They have a variety of serious physical differences such as added or missing body parts (limbs, eyes, ears, etc.), collapsed rib cages, protruding stomachs and large growths.
* Parodied in ''WebAnimation/HomestarRunner'': An Easter Egg in one of the Halloween specials shows the character Stinkoman (a character who is a walking anime parody) dressed up as Speed Racer for Halloween, and he comes up to 'your house' to get candy. One of the treats you can give him is a can with the word "Akira" printed on it. Guess what happens when you give that "Treat" to Stinkoman?
** "Waaaaaaagh!! ....It tickles!"
** ''Homestar Runner'' plays the body-horror angle for laughs on more than one occasion, such as the Strong Bad Email in which [[http://www.homestarrunner.com/sbemail148.html Strong Bad explores the possibilities of severing his head and body]]. "I think you're cute!"
* ''Website/GaiaOnline'''s Timmy experienced this trope in an UglyCute way after his legal guardian sealed him in a barrel of toxic waste just to see what would happen.
** It says something that even Timmy is grossed out by the Penanggalan from the Nightmare evolving item. "It even has a cute female companion-- eeeeeugh never mind I think I have to go lie down..."
%%* Artist [[http://www.alanmclark.com Alan M. Clark]] embodies this trope very well in his series of medical horror paintings. Try [[http://www.alanmclark.com/art/albums/PaintImages/o_blasted.jpg this painting]], as well as [[http://www.alanmclark.com/art/albums/PaintImages/o_ifyouhaveanyworth.jpg this one]].
* There is a well circulated picture called ''Lotus Boob''. The image of a lotus superimposed over a human areola and its implications of burrowed parasites is more than enough horror. Thank God that it's fake.
* There's [[http://www.snopes.com/photos/gruesome/fingers.asp an email]] on ''{{Website/Snopes}}'' with a .jpg attached of human fingers with lamprey mouths Photoshopped onto the pads. It's meant to be a joke: too much typing and mousing will wear holes in your fingers, har har!
* The infamous Goatse. ''How is that physically possible.''
** Encyclopedia Dramatica uses it on the 'kittens' page.
%%* [[http://www.youtube.com/watch?v=eo0RWj76fj4 Spengbab]]. Dear Lord.

%%* [[http://www.newgrounds.com/portal/view/494799 Saunich der Hejhaug]].
* ''Literature/WhateleyUniverse''. Horror author Michael Waite is dying of cancer. Oh no, that's just what the doctors think. It's much worse than that. After he 'dies', he wakes up in the morgue. For starters, he vomits up his own internal organs. It turns out the reason he was such a good horror story writer is [[TouchedByVorlons he's not fully human to start with.]]
%%* [[http://josephdonaldmyers.com/ Joseph Donald Myers]]
* ''Every single character'' in ''Roleplay/RubyQuest''. (Minus [[spoiler:Bella]], that is) Some of them aren't particularly obvious -- Red, for instance, looks perfectly normal in his first appearance. [[MoreTeethThanTheOsmondFamily And then he laughs]]. Others, though, are so twisted you can barely tell [[WasOnceAMan what they once were]], including Stiches and Number Six. Oh dear god, Number Six...
* [[http://neurologicalexcretions.blogspot.ca/2013/10/psychidae-cabin-in-forest.html This.]] A creepy bagworm moth enthusiast/med student who has trouble with a cheating wife. If you know anything about bagworm moths, you [[AndIMustScream can probably guess where this is going]].
* Hey kids, did you ever wonder what's the REAL reason why you put different Franchise/{{Pokemon}} into different Pokèballs? [[http://scythemantis.deviantart.com/#/d2wz5kd Well, wonder no more]].
* Many of the "powers" in ''Roleplay/SurvivalOfTheFittest'' Mini site spinoff ''SOTF: Evolution'' fall into this. Some are pretty "standard" as powers go, such as [[ThePowerOfTheSun solar-powered]] SuperStrength and invisibility, "memory absorption", {{Telepathy}}, and [[ShockAndAwe control over electricity]], while others are pretty [[WhatKindOfLamePowerIsHeartAnyway pathetic]]. Others, however, include things such as mold growing from the mouth and a character developing cat-like claws that are poisonous. The most notable one, though, goes to Johnny Marsh's "power", in which his ''skin'' is invisible, but the rest of him (muscles, organs, etc.) ''aren't''. This means that his muscles are completely visible like an anatomical model. This receives a LampshadeHanging when the scientists puts a full-body scuba suit on him to avoid him scaring the other subjects and interfering with the research. And then there's Billy-Jay Clarke's death in which he suffers a power malfunction, causing his [[EyeScream eyes to catch fire and melt out of their sockets]]...

* Many of the results generated by the [[http://www.springhole.net/writing_roleplaying_randomators/laboratory.htm Mutate-o-Matic]] fall into this.

* ''{{Literature/Worm}}'': Mannequin of the Slaughterhouse Nine turned himself into a puppet-like monstrosity whose internal organs are all housed in seperate transparent cases, all attached to a long-limbed body with ball joints at every joint.
** Bonesaw, also of the Slaughterhouse Nine, as a [[GadgeteerGenius tinker]] who specializes in organic bodies, might as well be a [[BodyHorror Body Horror]] ''[[BodyHorror Factory]]''.
*** [[spoiler:Grue]] got a taste of this when Bonesaw disassembled his body and positioned the various organs, blood vessels, and nerves across the interior of an industrial freezer ''while keeping him alive and conscious''.
** The more extreme Case 53's fall under this trope, sometimes even referred to as "monstrous". Sveta for example is a face surrounded by a mass of tentacles that instinctively attack anybody who approaches her despite her own intentions.
* [[http://akaichounokoe.deviantart.com/art/Shattered-Glass-273936881 This]], other than death, it causes your blood to turn to crystal and go through the skin. According to the story, albeit vaguely, it seemed to come in variation but in the most extreme cases the person is already dead and barely recognizable.
* [[http://www.youtube.com/watch?v=YJey74gmkLY Mostly weird things]] happening to peoples' mouths.
* The works of [[http://karlpersson.org/ Karl Persson]] are a little like what you'd get if you combined the brains of Creator/HRGiger and Sigmund Freud, and soaked the result in a bucket of liquid LSD.
* In ''Literature/TheSalvationWar,'' while Angels (like demons and "second Life" humans) have a healing factor. The angels sent to [[spoiler:Michel's concentration camp]] find out horribly that growing back does not mean growing ''right''. [[spoiler: The Angels who were nuked suddenly were less "angel" and more "Angel shaped cancer tumors".]]
* In ''Wiki/TheWanderersLibrary'' story [[http://wanderers-library.wikidot.com/abundance Abundance]], a stranger feeds a starving village by causing select villagers to grow new limbs and other meaty appendages, which they then cut off and eat.
* Killer Monster describing how he tortures his victims in 'The Camping Webisode' of ''WebAnimation/DSBTInsaniT''.
* ''WebVideo/TheCartoonMan'' parodies typical BodyHorror scenarios. Instead of some kind of horrific monster, Roy turns into a hyperactive cartoon character with giant eyes and WhiteGloves. It's still rather horrifying for everyone involved.
* From the twisted mind of Eyesglowyellow comes the {{Metokur}} chimera who -- in the first two stories it appears in -- turns the main character's head into a penis and another character into duct tape.
* In ''Literature/TheSaints'', [[TheCorruption corrupted]] [[OurGhostsAreDifferent ghosts]] are often heavily disfigured, either from SelfHarm or from other corrupted ghosts. [[TheUndead Thorolf]], the one corrupting the ghosts, is very decayed, with most of his skin rotting away.
* Kalia's OneWingedAngel form in ''WebAnimation/{{Dreamscape}}'' where 8 long arms with golf club-shaped hands come out of her back, as well as two smaller legs come out of the sides of her knees!
* In the "Beau and the Child Snatchers" chapter of ''WebOriginal/VoxAndKingBeau'', Beau encounters a (presumably) once-human child who has been kidnapped by a woman who lives in his realm. The child is described as not only missing his jaw, but being starved and malnourished with visible ribs and skin covered in "pus-filled sacs" and "bony growths".
* PlayedForLaughs in ''WebVideo/MonsterFactory'', where hosts Justin and Griffin [=McElroy=] abuse video game character-creation systems for fun and profit. Very basic examples include a character in ''VideoGame/TheSims 4'' whose head is approximately 4 inches wide.
* From Wiki/{{Killerbunnies}}, we have [[http://pre10.deviantart.net/2db9/th/pre/i/2014/107/1/a/killerbunny_xiv__io___nightmare_fuel__mcmorrison_by_akaichounokoe-d7ew006.jpg Io McMorrison]] and the fact that some if not all of her teeth grew through the surrounding tissues of her mouth.
* ConstableFrozen: Anna's cheeks in [[http://constable-frozen.tumblr.com/post/105697772498/cheeks cheeks.]]
* Discussed and played for laughs on ''WebVideo/SteamTrain'' in Dixie Kong's Double Trouble Part 10. Ross speculates about how horrifying it would be to turn into an elephant...and suddenly remember ''everything.''
* ''Advertising/WillItBlend'': In the episode "Tom's Hand", Tom decides to blend his own hand at the request of several viewers, so he is seen pulling off his own hand! The blended mix is red with blood and crumbled up bones and he warns the viewers "Don't drink this!"
* The Scientifically Accurate parody of Catdog is this. [[https://youtu.be/uOrSYkLWkZM]]
* The necromancer Sawyer in ''Literature/VoidDomain'' is fond of creating creatures that would fit under this trope.
* In Season 1 of ''Podcast/WithinTheWires'', TheNarrator uses an autogenic exercise to reveal and explain hidden, standard-issue {{Cybernetic|sEatYourSoul}} implants to a research hospital patient. A hollow between the patient's lower left rib and left hip is occupied by a mechanical creature with "many legs". It collects their memories. Later the Narrator explains replacement devices typically issued to patients of the Extensive Studies Lab, and elaborates on the surgical wounds incurred in gory, explicit detail. [[spoiler: The "creature" was a black box that monitored the patient's vitals, now replaced with a transmitter used to track the patient should they try to escape.]]
* ''WebVideo/DontHugMeImScared'':
** The strange creature that pops out of the egg in the third DHMIS is quickly smashed by the Duck Guy, leaving the cracked egg full of gore.
** Digital glitches in the fourth episode leave the main character's in horrible, distorted forms. Also, Colin's "Digital Mind" is some sort of squishy, red substance.
* ''Literature/HeroesSaveTheWorld'': The story practically begins with this. In chapter one, Simon, who is able to see how people are going to die, has a vision of "a forest of bodies, suspended, twisted into grotesque, wiry shapes." Simon dubs them "Giger trees."
* ''Literature/EntirelyPresentingYou'': It's a regular occurrence for the main character.
* The ''Webanimantion/SockSeries'' takes this trope and runs with it, heavily contrasting its [[ArtStyleDissonance cute artstyle.]]
