Where Stock Superpowers
make reality cry and sometimes meets Body Horror
Usually, when you gain some special ability, it will manifest in some fairly conventional forms. Energy blasts
, Psychic Powers
, steel skin
, control over different forms of matter
and varieties of magic
are all relatively common. Despite how fantastic some of these abilties may be, there is usually an underlying science or logic and at the least it seems normal or standard in the story's setting.
And then there are Lovcraftian superpowers. Now what makes abilities Lovecraftian can vary greatly but for an ability to be Lovecraftian, it usually falls under a few general rules:
1) The power in question is used by the bad guys. If the power is used by one of the good guys, the power is shown to be bad or harmful in some way be it to themselves, others, or the universe in general.
2)The ability or power must be unique and/or abnormal. It is usually a power that is either not possessed by more than one person, rare, or functions in a fashion that separates it from other standard yet similar abilities. An example would be if the ability to phase through matter by slipping there molecules through an object as a common ability versus someone who can phase partially out of sync with reality to move through obstacles. Both have the same result but one is rarer and functions in a different way.
3) The way the character gains the power is usually disturbing, horrible, unpleasant. While it may not be the process of gaining the power (as some characters are born with their power), the implications and circumstances surrounding the origins of the ability are almost always anything but nice.
4) The last but big rule is that the ability must clearly be unnatural or deviant in some way. Generally speaking this means that the ability must in some way go against the internal logic of the story and what should or should not be possible. Emphasis on the word should because, since the ability exists, it's not impossible just...wrong somehow.
While the most obvious way a power could be abnormal is if it bends, breaks, or flat-out ignores the laws of science and nature, it may be more subtle. Obviously, being able to bend space would be Lovecraftian but being able to invade someone's dreams would count as well.
For the less lucky, however, such new talents will have a disturbing
biological component. They find themselves able to sprout thrashing razor-tipped tentacles
, drool highly corrosive acid saliva, or extrude venomous thorns from their flesh. Alas, for these people have been Blessed with Suck note
and granted a squicktastic
The name originates from classic scifi/horror writer Mr. HP Lovecraft
, whose characteristic creations often seemed equal parts Nightmare Fuel and biology textbook.
A subtrope of Bad Powers, Bad People
, usually, possibly because Magic Is Evil
. Alternatively, this can overlap with Bad Powers, Good People
, though less frequently. May be a useful side-effect of The Virus
or The Corruption
. Often manifests as Combat Tentacles
and horrific Shapeshifting
(sometimes partial shapeshifting
), Bloody Murder
, or a Bee Bee Gun
, and is likely not quite controllable
. Can overlap with One-Winged Angel
, Power-Upgrading Deformation
and Shape Shifter Mashup
, and usually counts as a supertrope
of Spider Limbs
and, on a sillier note, Fartillery

Anime and Manga
- Allen Walker of D.Gray-Man has a monstrously deformed left arm that can transform itself into a much larger flexible and extendable claw arm, or a uzi/cannon arm. This only gets worse as the series progresses, with Allen's arm transforming into an even more deformed claw, only for him to later be able to remove it from his body and turn it into a sword. And that's just the main character; let's not get started on the various Noahs, Akumas and Third Exorcists.
- Mushizo of Ninja Scroll is a deformed hunchback with a hornet's nest growing straight out of his back.
- A few of the characters from the series are worthy of mention as well, such as a swordsman who has a hideous parasitic worm living in his stomach that attacks and kills anyone that is about to kill its host.
- Shino and the Aburame clan in Naruto turn their bodies into living hives for their Kikkai insects, but are portrayed much more sympathetically, and with only a few tiny holes in their cheeks as the only visible indicator of their trait (they wear rather concealing clothing, so any further changes are unseen).
- The Omake at the end of Shippuden episode 110 strongly implies that his eyes are empty sockets
- His eyes are seen from the side◊ in episode 149 of Part I. The manga says nothing either way.
- Heck, a lot of ninjas are like this. Kimimaro's blood limit is to weaponize his bones stands out as pretty freaky. But then there is any ninja who can use the 2nd level of the curse seal, that transforms their body into some monstrosity. Or Juugo, the original source of the curse seal, whose abilities are basically shifting his body into whatever the situation at hand calls for. Kakuzu passes into this territory as well, given that he is partially made of freely-controllable string and artificially extends his life by using his opponents like organ banks whenever something grows too old to work, plus there's those... things that he can create out of the string.
- Orochimaru transformed himself into a humanoid snake-like being who can extend his body to bizarre lengths(including his neck and tongue), puke swords, eat large objects, body surf and do other nightmarish things. Also, his real form is a big snake made of other snakes with his human head on the end.
- The ninja Pain has a lot of these. First of all, his ability to posses and use the bodies of dead people as if they were his own. Next, each body has it's own unique ability. The Shurando body that Pain uses can read peoples minds by ripping out there souls which can kill them. The Jingokudo body can summon the king of hell which is a large demonic head that uses mouth tentacles to connect to a living person and if they lie, their life-force is drained and the target dies. The real big one is Gedo or "Outer Path" which allows pain to not only manipulate the forces of life and death by resurrecting people, but he can resurrect thousands of people at once.
- The aliens in Parasyte are worm-like creatures that get into a human's brain through the ears and can transform their hosts bodies to have tentacles ending in sharp blades. Main character Shinichi gets a worm in his hand instead, which allows him to retain his free will and his parasite agrees to help him fight the other worms, since they want him dead too for botching his infestation.
- Awakened Beings in Claymore tend to start sprouting tentacles to rip people apart with. That's only the beginning of the Body Horror here, though...
- Mentuthuyopi from Hunter × Hunter, one of the elite Chimera Ants, has the ability to mutate his own body. There is seemingly no limit to the number of bodyparts or amount of distortion. He does some really cool stuff with this, too; his period as a centaur-thing was impressive.
- In Inuyasha, this is Naraku's main method of attack.
- In Ranma ˝ the character of Pantyhose (yes, really) Tarou is bad enough with his ability to turn into a giant Bull/Yeti-Thing in his first appearance. Just to show how Bad Ass (or Jerk Ass more like) he goes and mutates his body more to add tentacles. Obviously, this is form is based on the ushi-oni of Japanese myth, but that doesn't make it any less freaky.
- In Speed Grapher, one of the Euphoricsnote is a dentist who can make lots of tentacles made out of dental instruments sprout out of his back. Because backs sprouting tentacles and dental tools weren't terrifying enough on their own.
- Guyver tends to invoke this trope, especially with the first activation of the eponymous suit.
- In King of Thorn, infection by Medusa can grant this to those with sufficient willpower. The good news: you can make all your dreams into reality! The bad news: by having them explode out of your body like chestbursters. Body Horror doesn't begin to cover it.
- Xam'ds in Xam'd: Lost Memories. Even the most subdued use of their powers involves transforming an arm into a grotesque alien appendage or blade.
- Alucard from Hellsing honestly resembles something much more disturbing than a traditional vampire, like a primordial being of chaos that personifies hunger and bloodlust. Appearing as an amorphous blob full of red eyes and sharp teeth, he can turn into an ocean of blood capable of drowning an entire city, its waves made up of wailing human bodies; those engulfed in the ocean wind up impaled on spikes. He carries scores of familiars whose body parts he can materialize into form, like deforming his arm into a snout, which can then hold and fire a gun; these familiars are all individuals he has consumed, and there are thousands of them.
- And Alexander Anderson, once he plunges Helena's Nail into his chest, becomes a creature of endlessly propagating, thorny, strangling vines that cause anything unholy to burst into flame on contact. They can block bullets and immediately repair any injury Anderson takes, even the severing of his limbs or his entire head getting blown away.
- In AKIRA, Tetsuo manifests this trope in the Olympic Stadium when Colonel Shikishima tries to neutralize him; the flesh around the stub where Tetsuo's arm was fried off by the orbital laser shoots out in a massive bloody tentacle that attacks the Colonel. But then, later in the scene, Tetsuo gets shot by Kaneda's laser weapon. You see, Tetsuo is in so much pain that this trope suddenly combines with Superpower Meltdown. Naturally, Tetsuo's Lovecraftian Superpower Meltdown is just as bad as you can imagine it.
- In Bleach the 9th Espada Aaronerio has resurrection.
- Aizen during his fight vs Ichigo gets a gruesome transformation with the skin of his face splits in half
- Almost everyone from the Demon World in Wicked City has some kind of Lovecraftian Superpower. Main character Maki's Femme Fatalons is probably the tamest example in the movie, which says something. The only demon whose power doesn't evoke Body Horror is Dirty Old Man Giuseppe who wields lightning instead.
- Neon Genesis Evangelion gives us a nice helping of this with the angels, but especially Bardiel and Armisael, though Israfel's dance of death is also pretty bad. And, ahem, the entirety of the Instrumentality.
- Unit 01's stealing Zeruel's arm to use for itself also counts.
- Rebuild of Evangelion also gives us examples, both with Unit 02's "The Beast" mode, which turns it into a spindly, elongated monster with a huge, grotesque mouth that opens up halfway down its neck, and new-Zeruel's literal take on the saying "you are what you eat".
- All the devilmen in Devil Man gain their powers through Demonic Possession and Body Horror. It gets worse the more a demon takes over a human host or several merge into one body.
- Angel Sanctuary: So, so much. Rosiel's powers are exclusively this, and a few others get in on the act too.
- Fullmetal Alchemist:
- In Fairy Tail, the Strauss siblings' Take Over Magic has traces of this. Lisanna's Animal Soul Take Over is relatively benign, granting her the power to transform her body parts into that of various animals. Elfman's Beast Soul Take Over is a bit freakier, granting him the power to transform his body parts into that of various magical beasts. Mirajane's Satan Soul Take Over grants her the powers and forms of various demons.
- Immortals in Baccano! have the power to "devour" other immortals, acquiring all of their knowledge all the way down to muscle memory. This process is not pretty.
- In Attack on Titan certain humans have the power to transform into Titans. It's implied that the main difference between them and the other Titans is that they can control their power.
- Elder Toguro of YuYu Hakusho has the power to manipulate his physical form. This allows him to form his body into any weapon imaginable, travel unseen through the ground by liquefying his body, avoid fatal injuries by shifting his organs around, reattach severed limbs, regenerate from any non-fatal wound, and so on. Later on his body mutates to the point where he becomes truly immortal, unable to die of age due to being a demon, and being able to regenerate from anything including injuries to the heart or brain and obliteration.
- Younger Toguro bulks up as he uses more power. 100% has him going outright One-Winged Angel; his skin turns grey and his body becomes over-muscled to the point of deformity.
- The Apostles of Berserk. For some reason, fulfilling a person's most fervent (often dying) dream always involves turning them into a Lovecraftian horror.
- Bobobo Bo Bobobo is about a guy who can use his hair (including body hair and nose hair) to fight enemies.
- Variante has the main character obtain a monstrous arm that can mutate further (her arm ate a dog). She uses the arm to fight monsters.
- The Pillar Men from JoJo's Bizarre Adventure are Body Horror incarnate. Specific powers vary depending on the person, but they're all shown to be able to contort their bodies far beyond anything the most flexible, double-jointed human could even hope to do, and even crush their own skeletons into dust to slip through tiny spaces (fortunately, they also have an extremely powerful Healing Factor to undo it) and can effortlessly absorb any living thing into their bodies simply by touching them. More specific powers include burrowing inside other people's bodies and controlling them, extending their ribcages to impale opponents, sprouting chainsaw arm blades, rotating their arms like drills fast enough to create powerful whirlwinds and firing Razor Wind from holes in their bodies, and prehensile blood vessels that can inject literally boiling hot blood into people. When one Pillar Man is seemingly killed, his brain is able to escape his body and seize control of another person and when the leader is transformed by the Stone Mask, he gains Complete Immortality and the power to transform any part of his body into any animal, even when said parts aren't connected to his body (for example, he grows bird wings and fires razor sharp feathers at JoJo. The feathers then transform into piranhas to continue attacking him.)
- There's also the vampires (originally created from humans by the Pillar Men with the Stone Mask as a food source) who get instances of this, such as being able to contort and warp their bodies in numerous freakish ways; one of them has a nest of venomous snakes in his head, another uses uses his hair as a weapon, and first arc Big Bad Dio can split open his eyes with a thought to shoot out the liquid inside with the power and accuracy of a sniper rifle.
- And from the third arc onward, several Stands have those types of powers (such as a minuscule Stand that enters your brain through the ear canal and wreaks havoc on your nervous system or turns its victims into People Puppets, or one that manifests as a pustulant, tumorous growth either on its wielder (which covers them from head to toe and can be altered to make them look like a completely different person) or their enemy (where it grows into a grotesque homonculus/conjoined twin who then tries its damnedest to murder its host body). Those two examples are just two from early in the first arc to use Stands, and since the freakiness of said Stands only escalates in latter arcs... It's that kind of series.
- For One Piece, we have Nico Robin. It is very easy to forget that such a pretty woman consistently uses her powers to break the spines of her enemies. What are those powers, exactly? Sprouting bodyparts out of anywhere. However, unlike most other examples, we do not squirm in agony when she uses her powers, but instead relish when the bastards get what's coming for them. And as an added bonus, she's a part of the Straw Hat Pirates.
- In the New 52 Animal Man series, Buddy Baker becomes infused with more power from The Red(the metaphysical manifestation of the Animal Kingdom, and the animal equivalent to Swamp Thing's The Green), and his power to use animal abilities is morphed into actually physically manifesting animal characteristics. These transformations are visceral and not pleasant to look at.
- The Spike's mutant ability allows him to fire bone spikes out of his body. The film version has him shooting huge spikes out of his wrists. His teammate Phat can fill himself up with extradimensional gunk, growing to qroteque proportions but increasing his strength and durability exponentially.
- In the X-Men: Evolution series, the character who inspired him, Spykenote , eventually becomes completely covered in armadillo like plates which he can't get rid of. Although on the upshot, he gains the ability to launch spikes that are on fire.
- And of course, there's Wolverine's claws. Which are bone knives that slice through his forearms and hands everytime they extend. Good Thing He Can Heal indeed.
- This video parodies the problems that result from having the claws without the healing factor.
- And a parody video isn't actually needed. The comics and adaptations make no bones about the fact that having metal bonded to your skeleton and blades made of the stuff stuck into your arms is in fact not actually a good thing. Logan's healing factor is all that allowed him to survive having it done to him, and when deprived of it by power-dampening characters or tech, the adamantium in his body starts to poison him; he'd die without his powers. And at least before the bone-claw Retcon, driving those claws through his forearms and out of the back of his hands without his healing factor is insanely agonizing - surgery-without-any-anesthesia agonizing because that's kinda what's happening - to the point of being in real danger of having a heart attack on the spot. You're expected to kindly ignore all this when he loses his adamantium and writers who don't want to deprive him of his signature weapon say "Oh, he always had 'em, they were just covered with metal." We also learn just how damaging the presence of the adamantium was during this period, though: his healing and animal-based powers were in overdrive compared to how he normally is; apparently, the overwhelming majority of his mutant might is usually not available to him because it's busy keeping the deleterious effects of the adamantium in him at bay.
- Even after the bone-claw retcon, it's shown that popping the claws is still very painful. The first time he popped them in Origins, he screams in agony a moment later. By the present day, he's used to the pain.
- Predating the Spike is the even more Lovecraftian Marrow, whose bone growths were originally uncontrollable, random, and disfiguring. She would tear them out periodically to use as melee weapons, healing the wounds left behind with her Healing Factor.
- As well as the rest of The Morlocks living in the sewers.
- And then there's Tusk, who predated Marrow but was fairly similar... except he also had pods on his back from which he could spawn Mini-Me versions of himself.
- A oneshot Morlock was named MeMe. He absorbs people into himself physically to get bigger and stronger; at any given point, screaming humans melted into him and each other will be wriggling around on his body, with the limbs and faces of his less-intact victims jutting out every which way. As they shift and more are added, he never looks exactly the same in any two panels.
- A former X-Man with the charming name of Maggott had two parasitic slugs that crawled out of his belly and could eat anything. He spent most of his childhood nearly starving to death until his primary digestive system (the slugs) emerged.
- Johnny Dee of the 198 isn't a mutant, but his internalized parasitic twin is. It extends poison tentacles from his gut, and makes mind-controlling zombie dolls of anyone whose DNA it eats.
- One short-lived member of X-Force, Sluk, (and when we say "short lived", we mean "he was already dead when his team was introduced") had creepy tentacle things growing from his face and tentacular feet and hands. His teammates secretly hated him for a few reasons. One was that he was only handy in close combat situations and it was difficult to get him into the right spots a lot of the time. Another was that he wasn't exactly Mr. Personality. But mostly they didn't like him because he just looked really, really weird.
- Generation X foe Emplate had mouths on his hands that let him cannibalize mutant bone marrow.
- Spider-Man has on at least one occasion turned into a literal multi-limbed arachnid-humanoid creature. Even normal Spider-Man, in those incarnations where the sticky white silk he shoots from his hands is organic, arguably counts.
- Or the time when he fights Miss Arrow. Or, really, just her entire being. Bonus points for being a Lovecraftian horror in the FIRST place, madam.
- Minor Spidey villain the Squid can grow multiple tentacles and spew black ink from his skin.
- Spidey villain the Sandman can sometimes appear like this, as some adaptations have him using his ability to reform himself to make an arm come out of his head or other limbs where they just don't belong.
- The Bride of Nine Spiders from Immortal Iron Fist can summon hordes of spiders from her chest. This looks even worse than it sounds.◊
- Milder example in Fantastic Four: The Thing looks like a giant rock hulk.
- The various symbiotes in the Marvel Universe may as well be parasitic shoggoths, capable of forming tentacles, spines, extra mouths, and other grotesque metamorphoses.
- Most noticeable is Carnage, a psychopathic serial killer whose symbiote tends to turn into a cloud of barbed tentacles whenever it feels like it. Also, the reason his suit is red is that it's made up of the Venom symbiote mixed with Cletus Kasady's blood.
- Of course, in the Spider-Man: Web of Shadows videogame, Spider-Man's old "Black Suit" symbiote also has the potential to turn into this, if you buy all its upgrades. Waves of writhing, black tentacles covering half a city block is just the beginning...
- The Incredible Hulk is one of the most prominent examples of this trope.
- And perhaps one of the tamest. At least Bruce maintains a totally humanoid form. There are a number of gamma mutates who aren't nearly so lucky...
- Top Cow seems to be fond of this, with two parts of their Triarchy, Witchblade and The Darkness fitting the description. Combat Tentacles being just the start for both powers. The third of them, the Angelus, is more of a Holy Hand Grenade.
- It's possible that Guy Gardner's Warrior powers weren't supposed to invoke this trope, but the terrible '90s art on his solo series made his transformations deeply squicky.
- Most of the characters from Grant Morrison's run on the Doom Patrol.
- Perhaps most emblematically, Freak. A parasitic tentacle beast lives in her body. While she has total control over its tendrils... ick.
- The evil Green Martian D'kay D'razz, introduced in Brightest Day, uses her shapeshifting powers to frightening and effective use via Combat Tentacles and turning her head into a Venus Flytrap. Assuming a monstrous form comes naturally to her, since she's a murderous lunatic.
- In the Marvel Universe, the Celestial experiments on proto-humans that created the Eternals and mutants also created the Deviants. While the Eternals are superhumans with the ability to manipulate energy, the Deviants look like horrible monsters straight out of Lovecraft's works. Fortunately, most of them aren't that bad and just want to live in peace.
- Deadpool was an attempt to replicate Wolverine's healing factor that went wrong by having Wolverine's DNA injected into him. He had cancer that was killing him already, and they thought the healing factor would cure that. Unfortunately, the healing factor applied to his body AND the cancer cells, so while his superhuman immune system is perfectly capable of killing the cancer, the cancer can recover and mutate just as quickly.
- The first three issues of Generation Hope dealt with the manifestation of the powers of Kenji Uedo, the fifth new mutant since M-Day. His power is a sort of "techno-organic" shapeshifting, but that doesn't quite convey how very Lovecraftian they can be (the first image through the link even looks like an obvious Shout-Out to Tetsuo's transformation in AKIRA above).
- The miniseries North 40 deals with what happens when some kid reads the Tome of Eldritch Lore in a small town's library, triggering a Mass Super-Empowering Event of this type. The lucky ones get more or less Stock Superpowers like invulnerability, super-strength, and the ability to see through an animal's eyes. The other ones, however, get the ability to make man-powered killing machines, see through any photograph of themselves with their "new eyes" (which look like fanged maws), or just plain all purpose Body Horror of various and sundry varieties.
- In The Umbrella Academy, the Horror is pretty much the embodiment of this. He's said to have several monsters hidden under his skin. Whether or not they're from space or another dimension or something else has yet to be stated. However, according to some people in universe, they're horrible and disgusting.
- The Inhumans are a subspecies of humanity that the Kree genetically modified long ago. Those of Inhuman lineage manifest superpowers when exposed to the Terrigen Mist. The lucky ones retain their human forms after Terrigenesis. The unlucky ones don't.
- The DC Comics Elseworld Batman: The Doom that Came to Gotham is a Cthulhu/Batman mashup that presents Penguin, Mr Freeze, Poison Ivy, Two-Face and ultimately Batman himself as this. In particular, Harvey's scarred side becomes a flesh-portal to Lovecraftian dimensions, while his normal side is still capable of carrying on a conversation.
- "The Reaching Hand" (in Elseworlds 80 Page Giant) is another DC Elseworld, which reinvents DC's Rubber Man characters as Barely-Humanoid Abominations.
- The DC chracter Westley Dodds was the golden age hero sandman. When Dream of the Endless was captured, it wreaked havoc on the dream-scape and messed with peoples ability to dream or sleep. As the narrator says in Sandman #1 "The universe knows something's missing and slowly tries to replace it". Dodds became a vessel for a fraction of Dream's essence. What ability did a piece of the lord of dreams grant Dodds? Every night he dreams of crimes and sees murders and horror with the nightmares continuing until the perpetrator is caught. After he has no dreams for a few nights and then the whole thing starts all over again. While prophetic dreams don't seem too lovecraftian, keep in mind that Dodds is just a man and shouldn't have a piece of the Dream-lord's soul inside of him.
- In the Touhou story Imperfect Metamorphosis, the resident Blob Monster qualifies. Rin Satsuki was just a young Kirin with an interesting native power, and gained the power to absorb other people and use their abilities in turn, thanks to Eirin's experiments. At the cost of her own body. It goes without saying that she really doesn't take that well.
- In the same fanfic, Yuuka Kazami is capable of shapeshifting her own body into all kinds of horrid, twisted forms, all with a floral theme. This isn't just vine tentacles and root claws either. She can actually turn herself into Kaiju-sized plant monstrosities and weaponize every single part of her body. This power of Yuuka is justified in that she's actually an Elder God, albeit a very weakened one.
- One Naruto fanfic has the titular character taking Poisonous Person Up to Eleven. His saliva is poisonous (he can change the poison but has to flush his venom sac a few times to prevent cross contamination), he bleeds hydrofluoric acid, sweats nitroglycerine, and pees cyanide. What really sells it however is how he replenishes his fluids from spitting poison or bleeding acid. He manipulates his spilled blood and that of others, causing it to flow into any open wounds on his body as well as his eyes, ears, mouth, and nose. Kiba mentions that he hasn't been able to sleep alone ever since seeing Naruto use an Exploding Blood Clone to take out a group of bandits then absorb their blood.
- Tails of all people gets one of these in Sonic X: Dark Chaos after getting infected with Shroud parasites, complete with tremendous amounts of Body Horror. Among the highlights of his first transformation is his semen turning solid and slithering across the floor - before wrapping around him and hardening like body armor.
- Engineers from Tokyo Gore Police are genetically modified humans who sprout weapons from injuries they receive. For example, the first one in the film grows a bio-mechanical chainsaw after his arm is cut off.
- Shinya Tsukamoto's films often use this; most obviously his Tetsuo films, where the main protagonists (well, as far as they can be identified as such) invariably end up sprouting/fusing with various pieces of metal and machine, becoming hideous H. R. Giger-esque biomechanical monstrosities.
- David Cronenberg uses this a lot:
- Seth Brundle in The Fly (1986) gains the ability to wallcrawl, super strength, and even vomit a corrosive enzyme to dissolve food (or enemies). Unfortunately, he gained these abilities when he accidentally fused his genes with a fly, and slowly mutates into a grotesque giant insect/human hybrid. Blessed with Suck indeed.
- The Brood. While Psychoplasmics isn't necessarily a superpower, the ability to birth homunculi from your traumatic memories who end up subconsciously doing your bidding might be considered useful, if fucked up.
- Videodrome, where Max (probably) gets mutable flesh and a giant mouth in his stomach, which can apparently create hand grenades.
- In District 9, Wikus is exposed to alien fluid which slowly transforms him (starting with his arm) into one of the aliens. This gives him both an alien's strength and the ability to operate their weapons.
- Generally the Big Bads from the movies of Resident Evil gain this through the T virus.
- Perverse Mad Scientist Dr Pretorius in From Beyond, after getting his head torn off by fishlike ...things from Another Dimension, comes back as a Humanoid Abomination who takes entirely too much pleasure in abusing his newfound powers to manifest some of the squishiest, most disturbing forms ever put to film.
- The eponymous Thing from both the 1982 and 2011 movies usually takes pains to hide itself as those it absorbed... but once discovered or when thinking it's possessing the advantage, the fangs, claws, Combat Tentacles, etc. burst out every which way to kill and infest any nearby lifeform it can.
- Society: The members of Society can distort and mutate their bodies to use as a weapon; growing elongated arms is one of the more mundane uses.
- In Pathfinder, Rigg bonds with a Facemask. A successful bonding can benefit both parties, however there is a very high chance of ending up as a Meat Puppet. As a result of a successful bonding Rigg (who was Weak, but Skilled until this point) becomes REALLY over powered.
- Corrupted spellcasters in The Banned and the Banished are linked to animals, but the link is always perverse in some way. The first in the series gives birth to man-eating spiders, and they scale up from there all the way to twins who grow pustules that explode into rats. The only one who initially avoids this transforms into any animal he wears the skin of, and he later skins and wears one of the protagonists.
- In books by Clive Barker, villains (and otherwise) tend to have these.
- In The Abarat Quintet, the Prince of Midnight, Christopher Carrion, has the ability to distill his nightmares in physical form. They come out of tubes set in his skull and into a tank around his neck, cavorting in the fluid he breathes. On command, they can grow to many times their size and attack.
- Leeman Vole is a man who enjoys growing insects. On and in his own body.
- Leotho is a boy with a ravenous beast form. He works for Carrion in return for the antidote, which he needs continual doses of to remain human.
- Mater Motley, Carrion's grandmother and his eventual killer. The things she can do with needles...
- Midianites' powers in Cabal are pretty much all different types of this.
- A number of Jokers from the Wild Cards series. One that particularly pops to mind is Bloat. And Mother. And Ti Malice.
- The Denarians from The Dresden Files are often Mind Raped by fallen angels (and sometimes Not Brainwashed) and have the ability to transform into a demonic form. These forms are often a bit disturbing, the best example being the one who transforms into a giant mutated praying mantis. That bleeds praying mantises.
- Oddly enough, the kindly, feminine protagonist of Confessions of Super-Mom has a Lovecraftian power—her warped right hand constantly leaks a mysterious living fluid. She can blast it from her hand with incredible force as a way of knocking people over or making holes in weak objects, and she discovers that it can also be used as a stain remover.
- Another heroic example: Bes from The Kane Chronicles, whose trademark attack is scaring the crap out of his enemy by warping his face hideously. "BOO!"
- Drake from Gone ends up with a long, dangerous whip where his arm should be.
- As a heroic example, the Maximum Ride books give us "The Gasman," or "Gazzy" for short, who in later books gains the ability to incapacitate enemies with his super-farts.
- The Light Fantastic: Trymon gains this ability when possessed by the Things from the Dungeon Dimensions. It's not as powerful as one would think, though, since Rincewind punches him out. Literally.
- Imaro has the "gifts" of the Mashataan, grievous deformities like tentacles, tumors, over-sized limbs, discoloration, and more, but you get black magic and death rays in the process. Word of God is this was inspired by Wilbur Whateley's Body Horror from The Dunwich Horror but weaponized.
- The Behemoth features symbiotes that corrupt and empower people who are lucky enough to have one. They grant horrific transformations that are themed after parts of the body — the hero has armor made out of coagulated blood, another is a Winged Humanoid with a carapace made of his own bones, and that's not even counting the Leviathan made out of human fat.
Live Action TV
- Doctor Who has the Slitheen, who can disguise themselves by wearing people's skins.
- In Season 3 episode "Earshot", Buffy fears she might get a Lovecraftian superpower after touching demon blood. Instead she got Psychic Powers, though with great power came great suckiness that got her nearly insane.
- In one of the Heroes online novels, one man's superpower was to involuntarily grow spikes; he accidentally killed his wife this way, and then everyone in the van he was being transported to prison in (except for a guard who could turn into liquid).
- And then, of course, there's volume 3 Mohinder, who uses his own serum to grant him Spider Man-style powers, with the side-effect of growing scales over his skin.
- Maya could cry toxic tears.
- In another graphic novel, there was a character who breathed out chlorine gas instead of carbon dioxide.
- Pathfinders in Farscape can shoot poisonous bristles from the gills in their heads.
- Aside from the Corlata's ability to shapeshift in a particularly gruesome way, one of them apparently had the power to exude an explosive fluid from his hands.
- The Halosians can animate their vomit into a seperate entity.
- When starved, Delvians produce venomous buds from their skin and exhale clouds of paralysing spores.
- E'Alet, the villain from "A Prefect Murder", could grow swarms of mind-controlling sgabba flies inside his skull and emit them.
- The warp-spasm of Cuchulainn from Celtic Mythology is all this. Think the Incredible Hulk, only uglier.
- Longrunning 2000 AD strip Sláine (being a fusion of Celtic mythology, Robert E. Howard novels and the good old fashioned, classic 2000 AD, punk aesthetic) has its eponymous hero (an appropriate fusion of Cuchulainn and Conan, with a punk aesthetic) warp-spasm similarly.
- A feature of The Dreadful Secrets of Candlewick Manor, a supplement for Monsters And Other Childish Things. The more powers you have, the more creepy other people find you and the less you can pass for normal. (In the original game, you have a mon companion. In Candlewick Manor, you have an eerie power which (usually) manifests physically, or else mentally or psychically.)
- Sorcerers in the game Sorcerer who have Parasite demons commonly have this kind of power.
- Many of the mutations mutants and Chaos champions gain in Warhammer and Warhammer 40,000 fit this, usually a physical boon specific to the chaos god they represent. If they are unlucky, however, they might get something like an eye on their navel or an emu's leg.
- Hell, an eye or emu's leg is nothing compared to the grotesque explosions of tentacles (with breasts and tongues if we're talking about Slaanesh) that you can get stuck with!
- Chaos Marauders, at least in their Age of Reckoning manifestation, use Chaos energies to spontaneously mutate their limbs into a variety of crablike claws and similar weapons.
- In fact, a persistent danger to Chaos champions is that their gods will "gift" them with so many of these mutations that their minds and bodies collapse. These are known as Chaos Spawn.
- Possessed Marines— Chaos Space Marines that invited chaos daemon into their bodies. In addition to having an incarnation of rage and hatred in their heads it also grants them extensive and very unpleasant-looking mutations. Obliterators and Mutiliators are victims of a virus that makes their bodies mutate into demonic hulking monstrosities that can grow weapons (long range and close combat respectively) and armor. The process is very painful and the result is not pretty.
- Second generation Genestealers look like this. They are regular humans with one or several adaptations (boneswords, extra limb, chitin armor, etc.) from their Eldritch Abomination overlords. Most of them are able to pass for humans in low security areas, but have increased combat capacity.
- Several Dungeons & Dragons prestige classes do this. The Alienist is very explicitly Lovecraftian, as it involves abandoning their sanity, summoning pseudonatural beings from the Far Realm, and modifying their bodies with otherworldly effects. There's also the Vermin Lord (who gets covered in bugs), the Fleshwarper (monster flesh grafts for all!) and the Cancer Mage (how does "Sentient Tumour" sound as a superpower?). You can also take Aberrant feats, which improve your body while making you look really messed up. Special mention should be made of the 3.0 Song and Silence Prestige Class "Fang of Lolth", who slowly gives over her body to the image of the above-mentioned Spider-Queen. Unhinged jaws, bug-eyes, hairy limbs, EXTRA limbs. There are also TWO versions of the Pseudonatural Creature template. As well as a Half-Farspawn template. Both of which add tentacles to an existing creature (although, the first is more of a template for creatures native to Lovecraftian dimensions that happen to bear some resemblance to their Material Plane equivalents, rather than a modification).
- The core rules have the Phantasmal Killer spell, which essentially makes you appear to your foes as though transformed into a alien monstrosity. If it works, they die of fright.
- Another notable one is called the Warshaper, which basically involves taking a character that can change shape in some way, and going nuts with it. Sprouting claws, horns, mouths and spikes at will, being able to double the length of limbs for better reach. Growing more limbs, all of the above at once...
- The Expanded Psionics Handbook doesn't have anything explicitly aberrant (besides illithids and intellect devourers), but many of the powers available to the psychic warrior involve sprouting claws and spitting acid. One of the higher-level abilities, Form of Doom, makes the psychic warrior's body stronger and faster, "complete with an ooze-sleek skin coating, lashing tentacles, and a fright-inducing countenance".
- Its expansion/followup, Complete Psionics, has illithid feats and the related flayerspawn psychic prestige class, which allows characters to take on mind flayer traits (up to and including brain-extracting face-tentacles).
- Fourth Edition warlocks (particularly the Star-Pact variety) can attack foes with writhing tentacles and swarms of crawling unearthly vermin that sprout directly from the enemy's flesh, or simply attack their sanity with visions and apparitions of this nature. Gained, as the name suggests, by channeling the powers of various cosmic God-beings.
- The Pathfinder campaign setting offers sorcerers different bloodlines. One of them, the Aberrant bloodline, gives the practitioner slightly 'wiggy' anatomy (which gets progressively more so as he gets higher in level). Starts out with the ability to spit acid, ends with Aberrant Physiology, in which your character's so messed up, he's immune to critical hits.
- The Vivisection Alchemist's recommended Discoveries are things like tentacles, parasitic twins, Tumor Familliars, and vestigial arms. And their base skillset is focused on making furries from animals who piss them off.
- A Forgotten Realms special is the spellscarred multiclass feature, which has all kinds of nasty Body Horror powers. Including unhinging your jaw to take a bite out of your enemies, bleeding on your sword to make it blister with plague, and creating a rope of flesh that binds you to your target so they can't escape you.
- Dragon #s 296 and 300 introduced the Monster Cultist prestige classes. Give yourself over to a monstrous god, and you gain the powers of their natural worshippers ... at the cost of becoming more like them. Examples include Sphere Minion (beholders); Illithidkin (mind flayers); Snake Servant (medusas); Waker of the Beast (tarrasque); Faceless Ones (doppelgangers); Deep Thrall (kraken); Shoal Servant (kua-toas); and Tiger Mask (rakashas). Anything that involves shifting your Creature Type from Humanoid to Aberration is probably applicable.
- In Vampire: The Masquerade is the Obtenebration discipline, which at a certain level allows the user to make tentacles out of shadows.
- Don't forget what Tzimisce can do with their Vicissitude, which allows them to sculpt themselves or others into slimy pus-heaps or powerful mutant monsters, as they see fit. One sourcebook played up the Lovecraftian connections by making it a parasitic virus from the Umbra. This was not well-received and eventually struck out, but the idea remained that Vicissitude wasn't so much a proper Discipline as a virus devised by the clan's antediluvian for some foul purpose. The Gangrel's Protean discipline also had weird shapeshifting, though usually much less spectacularly disturbing.
- Fomori have this and The Corruption as pretty much their entire schtick in Werewolf: The Apocalypse: sure, you can get Super Strength, but you're gonna look like a reeeally ugly Hulk for the rest of your life. Or that convenient armor power you just got takes the form of a thick, chitinous exoskeleton that covers your entire body. It doesn't stop there and Storytellers are often encouraged to go further down the Humanoid Abomination route. Justified by the fact that Fomori get their powers from being fused to a Bane on a physical and spiritual level, and that for each Power Point they get at creation, they must take on an equivalent Taint to balance it out.
- Also from Werewolf: The Apocalypse, the Black Spiral Dancer tribe of werewolves. While other werewolf tribes get gifts that allow them to talk to spirits or heal with a touch, the gifts of the Black Spiral tribe are more likely to be hideous mutations.
- New World of Darkness
- In Hunter: The Vigil, the Cheiron Group's "thaumatechnology" is based on implanting monster organs and body parts into a human host.
- The reality deviant worshippers in Second Sight get a whole section of Body Horror-themed features and rituals.
- Sin-Eaters have the Caul Manifestation, allowing them to assume a whole range of horrifying forms. Most notable are the Industrial Caul (which allows them to implant objects in their body) and the Phantasmal Caul (which lets them transform into a living nightmare that can induce paralytic fear or outright madness).
- And then there's the Centimani of Promethean: The Created, Prometheans who turn their back on the Great Work and embrace Flux. They can buy all sorts of twisted mutations, from tentacles to extra organs to the ability to turn into a puddle of sentient liquid.
- Similarly, the Zeky get a whole bunch of unwholesome Transmutations based around atomic energy and its side effects. Three words: Mind. Control. Tumor.
- In Vampire: The Requiem, a few of the bloodlines have these kind of abilities. Take the Carnival, whose special Discipline ranges from contortion tricks to merging with another vampire to form a hybrid. Or the Noctuku, who alter their flesh so they can absorb more blood and better digest vampiric flesh. Or the Norvegi, who lack fangs but make up for it by producing bony spines that allow them to feed through their fingers. Or...
- In Mage: The Awakening, Mages have Branding Paradox, where the Abyss warps their body in various ways, which can include temporarily granting them strange mutations of their bodies (such as horns, claws, tails, and, of course, tentacles). There is also a Left-Handed Legacy called "the Legion", whose whole shtick is that they give up parts of their body to the Abyss, and receive mutated transplants in return.
- The fourth clause of the Contract of Mirrors allows changelings to turn a limb into a weapon, their skin into bark, etc.
- Mummies are all over this, able to call up eldritch abominations or turn themselves into avatars for them.
- Demons are basically eldritch abominations in human form, and when they need to, they can reassume their true forms.
- In the Glorantha setting of RuneQuest, Chaos Features (powers granted by exposure to "primal Chaos") often have a physical side effect like this—But some folks get Chaos Flaws instead, all side effect and no power.
- In Cthulhu Tech, Tagers and their Nyarlathotep-worshiping counterparts, the Dhohanoids, manifest a Guyver-style ability to transform into Eldritch Abominations.
- Nightbane. A Palladium horror dark fantasy, where your Blessed with Suck powers are to transform into an inhuman, grotesque, powerful form.
- Exalted has a fair number of horrors with these abilities. Chimera Knacks for Lunars, some of the freakier Yozi charms for Infernals, the Abyssals and their freaky undeath powers...and let's not even get into a discussion of the Wyld. (With the Broken-Winged Crane expansion, Infernals can even literally turn into a shoggoth.)
- Voidtech Charms for the Alchemicals generally appear as a techno-Lovecraftian device made of equal parts rust, meat and scientific blasphemy.
- 3e Infernals are slated to have some new weird things, like the prerequisite for Mind-Hand Manipulation being a brain tumour.
- You can learn the Celtic "warp-spasm" in Scion. The picture that accompanies it shows someone in the middle stages of transformation, and it isn't pretty (he's effectively turning into a mutant crow).
- One of the many consequences of taking high levels of Taint in White Wolf's Aberrant. Low-level aberrations might include glowing eyes or bulging muscles, while the higher levels of aberration include becoming too hideous to view or having an entire vestigial body. By the time of Trinity, set in Aberrant's future, as far as most people are concerned, all Aberrants are mutated, twisted freaks... though as the game goes on, it's revealed there are a good number who still look pretty human.
- In general, Point Build System games such as Champions or GURPS give a player the option of building a character with a repulsive appearance in order to gain points that can be applied to extra powers.
- GURPS lists the Battle Jaw, Tentacle Transplant and Ripsnake as potential body modifications, which can come as quite a shock to the unsuspecting.
- Twisted Adepts from Shadowrun have embraced the dark side to gain more points to spend on powers. The effect also causes physical mutations and the game suggests that these mutations should represent the powers gained, with an example being supernatural toughness coinciding with growing scales.
- Chaotic's Stelgar: though originally a very spiny starfish and slightly creepy◊, his new look makes his old look seem cute and snuggly◊
- Magic: The Gathering sometimes does this with cards like Unstable Mutation and some of the versions of Unholy Strength feature frightful assymetry. Other cards, like Fallen Angel, involve sacrificing creatures to pump them up.
- Pandemonio's Sacraments, in large part, which let you do things like summon tentacled horrors and giant worms; cause a vicious, gigantic toothy grub to manifest by tearing itself partway out of your stomach; or rip off your skin like a tear-away dress to reveal a demonic form underneath. Blasphemies are nicer in this regard, but still let you do things like fuse people into a single grotesque entity, turn your hands into crab claws, or literally turn your guts into snakes and eels... and it's probably better not to describe what exorcisms tend to entail, though the fact that they're solely the purview of a class of magic known as "Blasphemies" is probably a hint they're not pleasant.
- The Las Plagas parasites from Resident Evil usually spawn such mutations in those they infect. Even villains who don't go full-on One-Winged Angel tend to have giant claws (Krauser) and Combat Tentacles (Saddler before fully transforming).
- The T Virus usually just creates zombies, but properly treated, victims can be turned into boss monsters such as the Tyrant and the Nemesis. The point of the virus was to mass-produce these guys - the zombies and most everything else are the result of accidents.
- The G Virus gives you a healing factor, claws and Combat Tentacles at the cost of your higher brain functions. You also end up degrading into a giant, cancerous mass over time. Lovely.
- As Albert Wesker, who himself gained quite a few of these powers, revealed, this was the ultimate intention of the Ouroburos plague; to transform select humans into superpowered monsters and kill all others.
- Alexia in Resident Evil: Code: Veronica has similar superpowers as a result of the Veronica-T virus.
- The hero of FPS The Darkness, Jackie Estacado, sprouts a pair of snapping serpentine demon-heads from his shoulders, as well as producing dark tentacles to impale foes and destroy walls as needed.
- In the first Baten Kaitos game, Geldoblame is transformed into a hideous deformed monstrosity after infusing himself with the power of Malpercio. Jiggle Physics are involved, which is as unpleasant as it sounds.
- BioShock's "Insect Swarm" plasmid causes a small hive-like growth to form on your palm, which allows you to throw live swarms of hornets at your foes.
- Most of the other plasmids, which are injected into yourself in order to rapidly modify your genetic structure, combine this with Elemental Powers.
- All of the Vigors in BioShock Infinite have shades of this, most notably Murder of Crows, which works similarly to Insect Swarm above and causes Booker's hands to sprout dark feathers and talons, and Undertow, a Mind over Matter-themed Vigor that causes Booker's forearms to develop cephalopod-like suckers.
- Similarly to Warhammer and Warhammer 40,000, ADOM features various "corruptions" that you eventually gain after enough exposure to the forces of Chaos (from traps and Chaos beings, but also simply being deep in a dungeon). These most commonly take the form of Lovecraftian superpowers - although as "superpowers", they're mostly examples of Blessed with Suck. Also similarly to the Warhammer games, taking enough corruption will turn you into a "writhing mass of primal Chaos".
- Prototype has the main character capable of significantly altering his own body, allowing him to grow everything from claws to Combat Tentacles to better destroy absolutely everything around him... or he can eat someone to steal their appearance and blend into a crowd. Combine this with Super Strength, Super Speed, and Nigh-Invulnerability, and you've got one very scary Villain Protagonist on your hands.
- Metal Gear Solid 3: Snake Eater has The Pain, who is technically covered in hornets. He attacks by spitting hornets that burrow into Snake's flesh unless removed.
- Yuri and other Harmonixers (except Shania) in Shadow Hearts fuse with various demons, in ways that cause their bodies visible pain and take a toll on their minds. The villains tend to be even more so.
- The Spines and Thorns powersets from City of Heroes / City of Villains.
- Final Fantasy XI has this in Blue Mages and the backstory's precursor experiments toward creating the Blue Mage. The original experiments included grafting monstrous appendages and material to people, which gave them power but either drove them insane, or transformed them into flan (spell-casting blobs) or soulflayers (read: D&D's mindflayers with the serial numbers barely filed off). When they attempted to just graft a portion of a monster's magic and spirit to the experiments' subjects, they created the first viable blue mages, but even then, a Blue Mage gains their power from assimilating their opponents, and if one pushes too far, has the risk of becoming a soulflayer as well. Which brings some Fridge Logic horror. Just imagine how many players have unlocked Blue Mage on any given server...
- In fact from the combination of the danger of their powers, and the risk of being killed by allies who believe they're close to the turning point, it's said that there has never been a blue mage who died of natural causes.
- Saki of Sin and Punishment, as a result of absorbing Achi's blood (she turns out to be an Eldritch Abomination, incidentally), gains the ability to transform into a really scary-looking Kaiju that can teleport, shoot giant lasers out of its claws, and grow to such immense size that it is fully capable of battling entire planets. As long as he's paired with Airen, he can control it. If not... it's not pretty. After it activates, even in his human form, he has disturbing looking patches of alien flesh on his body.
- The Soul Series has a couple of examples. The various forms of Nightmare have a horribly disfigured and mutated arm, and Abyss, the ultimate form of Zasalamel...yeah.
- In the Scott Pilgrim video game, Todd has this attack◊. It's a Shout-Out to AKIRA. Is there any wonder?
- Baldur's Gate. In Shadows of Amn, the main character eventually gains the power to transform into the Slayer, a giant demonic creature with huge claws that's nearly unstoppable. Unfortunately, there are side effects.
- Dead Space: Unitologists believe that the power of the Marker will allow them to become a new, immortal form of life... and they're not wrong. It just so happens that this "immortality" involves losing your mind and having your body transmuted into a specifically-formed zombie with no purpose than to harvest biological matter to propagate your species.
- Some lucky Infected in Left 4 Dead gain considerable powers, at the expense of their... human appearance. May not apply because you can't "Choose" to become a special infected, but the theory is there anyway.
- Being what amounts to a cute little girl with an eldritch tentacled horror attached to her back, Disgaea 4's Desco naturally comes with quite a few of these.
- Being a direct and very obvious Shout-Out to Tetsuo, K9999 has this power, particularly as part of his Desperation Attack (which, yes, turns his hand into a horrifying giant tentacle of flesh).
- Subverted with Double, from Skullgirls. She is an Eldritch Abomination who normally looks like she would possess this kind of thing, but in reality, she's a Voluntary Shapeshifter with the ability to assume the form of any of the other fighters and use their powers in battle. Ms. Fortune is a better example; her power comes from her undying body and nigh-infinite Healing Factor, allowing for such things as using High-Pressure Blood for propulsion and ensnaring her opponents in her own muscle fibers. Filia is also an example, with a parasite stuck to the back of her head that can attack with Combat Tentacles.
- Actually, the only ones that are not examples are Parasoul, Cerebella and Valentine. Peacock was once a mutilated girl turned into a cyborg and Big Band was turned into a cyborg when he was gunned down by his fellow police. Regarding Painwheel...well, an image speaks a thousand words◊.
- A more subtle example are the deformed, Eldritch Abomination-worshipping swampfolk and tribals in the Fallout 3 DLC Point Lookout, which, while they don't have tentacles or other Lovecraftian appendages, do have superhuman durability and magical armor-ignoring weapons.
- The Flood in Halo, once they've infected an organic body, have the ability to morph it into various shapes to aid in combat, most commonly sprouting Combat Tentacles and spikes. At a certain point they start developing Pure Forms: Flood creatures built out of a mishmash of organic material which can shift forms fairly drastically to fit into a variety of situations, from aptly named Tank Forms, to the intermediary Stalker Forms, and finally the Ranged Form.
- In Kirby 64: The Crystal Shards, those possessed by Dark Matter gain some disturbing abilities. King Dedede in particular becomes able to sprout either a giant eye (to shoot shadow balls from) or a giant maw with razor-sharp teeth from his stomach. Y'know, for kids.
- Nero Chaos in Tsukihime is a magus whose entire body consists of the loosely drafted together biomass of 666 wild animals, beasts and legendary monsters that he can either send out in their true form or, more in tune with this trope, use partially, such as generating black tentacles, fangs, claws and such out of his flesh.
- Tiberius in Demonbane is a walking, immortal, perpetually rotting corpse. No matter how damaged he becomes, he can regenerate as long as his grimoire is intact (which he hides inside his soul, making it hard to get at). His methods of close combat involve using his intestines as tentacles or shooting his ribs like javelins.
- The Cubi in Dan and Mab's Furry Adventures can reshape their back wings into Combat Tentacles with razor-sharp ends that can cut rock.
- In The Non-Adventures of Wonderella, Wonderella, unlike her DCU counterpart, has "like a spillion powers when tied up."
- Harp's Bane and Gravehouse in Necessary Monsters both have rather unsettling transformations.
- Shadowgirls, which has literal Lovecraftian powers (like "turn into living shadow" or "become a snake-monster made of light").
- Alcolla in Reliquary becomes an angel, but not the attractive kind: She looks more like an undead shadow creature.
- Vorte from Hitmen For Destiny can puke up a sticky liquid and use "deadly headspikes". Also at some point Bianca grows a tentacle on her back.
- Nergal demons in the fancomic Grim Tales from Down Below have Combat Tentacles that can form just aboutanything!And also a gun.
- The Infernomancer from Dominic Deegan fits this trope, best seen here and here.
- Homestuck: Rose Lalonde, after spending most of the early Acts communing with the Dark Circle of Horrorterrors, goes grimdark and gains a massive black aura that manifests as thorned tentacles.
- After Rose's prototyping takes hold, all the game's enemies (including the Royalty of Derse) gain prehensile chest-tentacles. This is also a natural consequence of the prototyping of Glyb'golyb in the trolls' Session.
- Redd has Esmerelda Bizarre, who pretty much has the works: Worships an Eldritch Abomination called the Flesh God, has thousands of tiny screaming faces of long-dead Human Resources sacrificed to him long ago on her arms, the ability to summon Combat Tentacles, Eyes That Do Not Belong There, More Teeth than the Osmond Family provided by Too Many Mouths, raising the dead, yadda yadda yadda... but she's a pretty nice girl! She's even a bit of Combat Medic at IBISEC.
- Pretty much everything in Mortasheen that has a power of any sort.
- Squid Kid in the Metro City Chronicles can make indestructible tentacles sprout out of her back at will. When she leaves them out for too long, she starts turning all amorphous and inky-looking.
- Shadowspawn of the Global Guardians PBEM Universe is an Eldritch Abomination from outer space who generates tentacles of shadow and darkness that can drain the life out of people. In addition, Shadowspawn itself is a Clingy Costume that is slowly devouring the human being it has engulfed. When it finishes eating its current "host", it will move on to another host.
- Dagon, another Eldritch Abomination, has fused itself with a human being whose body was transformed into the spitting image of a Dungeons and Dragons mind flayer. The tentacles that have replaced his mouth are not just for show; they can inject a rotting poison into his victims.
- The Swarm can transform herself into a horde of carnivorous cockroaches. The very thought of having this power has driven her stark raving mad. She's not a cannibal serial killer. Similarly, Hive can transform himself into a swarm of wasps, but has taken it a lot better than The Swarm has and uses his powers to fight crime.
- Bloodstone of the Sinister Circle is a "hemokinetic". That is, he has telekinetic control over blood. His usual first move in any fight with a hero is to gather up some nearby blood to use as a weapon, and he gathers it from any nearby innocent bystander who is unfortunate to be close enough to become an unwilling donor.
- Ruby Quest, quite literally, in the form of "the treatment". Apparently a universal panacea (even for death), it causes ongoing mutations and loads of Body Horror, which give its victims powers as a result (for instance, a third eye with some sort of true seeing in Ruby's case). Apparently the use of it also allows an Eldritch Abomination called "Cjopaze" into this world, though that's never made quite clear.
- Carmilla in the Whateley Universe, since she literally is a Humanoid Abomination: one of her grandparents is Shub-Niggurath, on on her mother's side she's directly related to Cthulhu and the Deep Ones. And you thought your family was freaky. She's got the Combat Tentacles and wierd shapeshifting down. In one story, she split her face open to reveal what it looked like inside, and scared a superhero so bad he wet himself.
- A lot of Whateleyites have such powers, due to the Mythos nature of the universe, not to mention plain(!) old mutations. Tennyo's is subtle, but she's no longer remotely human due to channeling the spirit of an ancient construct designed to destroy (or EAT) Great Old Ones, has (occasionally, when she's mad) anti-matter for blood, and even when her powers are negated, can inspire pants-crapping terror merely by making eye contact. Or Fey, who is the reincarnation of a GOO-level elven sorceress, and is supernaturally, mind-controllingly pretty, and can throw around spells that other mages can't even learn. Or more mundanely, Tool (now Demona) who used to have a body in constant flux, which occasionally reacted to his impulses by sprouting erections all OVER! Or any mage who decides to play around with GOO powers. Or any number of GSD sufferers, who have all manner of horribly inhuman transformations to contend with, up to and including And I Must Scream levels, like Puppet, whose blood is so horribly toxic it KILLED HER, and she now lives by occasionally-malfunctioning mad-science. Or... well, most of the Thornies, actually. Or the Foob, who got Mythosed fighting off something we've yet to find out about, and turned into, essentially, a mini-Cthulhu, which dramatically enhanced his psychic powers, rendering him basically unable to tune out the mind-numbing horror people experience when they see his physical form. Whateley's pretty screwed up in places.
- Worm: Night (of the villain duo Night And Fog) turns into ... something incomprehensible, fast and super strong as long as nobody can see her.
- The effect Rachel has on her dogs counts as this as well.
- Echidna definitely counts. She absorbs any dead tissue she encounters into her body, which has accumulated over years into a massive amalgamation of jumbled body parts below her waist. When she comes into contact with something that's still alive she can create copies of it that are always distinctly wrong in some way, and homicidally insane to boot. And if she copies a parahuman, the clone will have their powers or a similar variation on them.
- Throw a rock at the SCP Foundation and you'll probably hit something of this nature.
- There's a species of lizard, the Texan Horned Lizard, that sprays blood from its eyes when threatened.
- Other species can stab their own ribs through their poison glands and out their sides.
- Sea Cucumbers can eject part of their digestive system when threatened. They also can near-liquefy themselves to fit through small spaces.
- Bombardier beetles can spray a jet of boiling acid from their abdomens.
- No, not a jet. A small chemical explosion. Oh, and they don't have an orifice for it to come out of. It just explodes out through their skin (fortunately it's a pretty weak explosion, so they aren't really hurt by this).
- Starfish feed by moving their stomachs out through their mouths and over whatever they're eating. They also clone themselves when they lose a limb.
- Some species of starfish have clams as their favorite food. How do they get to the tasty clam meat inside? By breaking open the shell with a rock like an otter? No! They latch onto the clam, Face Full of Alien Wing-Wong-style and force the shell open! The clam can only watch in horror as its only line of defense is pulled away and the starfish's stomach acids leak inside!
- Most (if not all species) of octopuses can: strangle and crush enemies or prey with their tentacles, confuse them by spraying black ink into the water, paralyze them with potent toxins from their beak-like mouthparts, or change their coloring at will. Some species can even change their texture and limb orientation so they look like harmless seaweed or fish. It's like Prototype, but in real life!
- The mimic octopus can mimic twelve species, one of them being a venomous snake.
- Spiders inject digestive acid into their prey to make it nice and squishy before sucking out the liquefied organs. They rinse and repeat until all that's left are the totally inedible parts
- Marine Cone snails possess some of the prettiest shells of any mollusk- they are also extremely effective predators, several species fully capable of killing a human being.
- How does something limbless, nearly blind, and slow as a, well, snail hunt fast prey like fish? Obviously by tracking prey by smell and the motion of the surrounding water, and carefully aiming its organic tank turret which fires a harpoon-tooth laced with custom multicomponent neurotoxin cocktails tailored to its current target type, silly.
- The venom of the cone snail is being studied for medicinal uses because it apparently hacks the victim's nervous system; certain species produce a cocktail for hunting fish capable of completely paralyzing and killing an aquarium-sized fish in under half a second.
- Then they reel in and engulf their prey like a real-life Kirby.
- Which by the way is potentially still alive but paralyzed and slowly suffocating, if the cocktail mix wasn't perfect.
- Remember the part about them having pretty shells? Most reported human deaths have occurred when the person picked up that pretty shell from the bottom of the lagoon and felt a pinprick.
- And then, of course, there's that one critter that drives away enemies, and can even temporarily blind them, with a horrible-smelling sulfuric mist from glands near its rectum.
