[[caption-width-right:250:Worms, worms? I hate worms. They drive me crazy.]]

->'''Buffy:''' You and bug people, Xander. What's up with that?\\
'''Xander:''' No, but this dude was completely different than praying mantis lady. He was a man ''of'' bugs, not a man who ''was'' a bug.
-->-- ''Series/BuffyTheVampireSlayer'', "What's My Line, Part Two"

Sometimes, when you want a [[GrotesqueGallery really scary]] monster, a [[AttackOfTheFiftyFootWhatever giant insect]] just won't do. They've been done to death and look really [[SpecialEffectsFailure cheesy]] to boot. But you still want a bug monster -- what do you do?

Well, you call this guy. He isn't just ''one'' bug -- he's ''[[TheSwarm millions]]''! Millions of tiny creepy crawlies make up his body, as if his entire body is composed of SynchronizedSwarming controlled by a HiveMind. Sometimes it's worms, sometimes it's insects -- [[BeeAfraid bees]] are always good -- and sometimes it's just any creepy thing you can think of.

Villains like this aren't always the most lethal, but are often very hard to hurt. Trying to punch one is like trying to punch water (only far more disgusting). In some cases, they are almost impossible to kill, because if even ''one'' of the creatures that makes up its body survives, there is the possibility that [[FromASingleCell it will return (though it may take a while)]]. KillItWithFire is often your best bet.

In real life, these are called [[https://en.wikipedia.org/wiki/Colony_%28biology%29 colony organisms]].

Could be considered an extreme of the TotemPoleTrench. At times the members can retain their individuality and are just really well-coordinated. This trope is almost always combined with HealingFactor or even [[FromASingleCell From a Single Maggot.]] Just don't confuse him with TheWormGuy, or VideoGame/EarthwormJim, or [[ComicStrip/ThePhantom The Ghost Who Walks]]. OneToMillionToOne is a variant where a creature can become TheSwarm, but it isn't its common form. See also CombiningMecha for the mechanical counterpart of this trope, and BodyOfBodies for the vertebrate one. One justification for a PestController.



* An ad for Creator/TheBBC had a head made of disembodied heads. People complained.
* This [[http://www.youtube.com/watch?v=XVTo4y5e08k Duracell Ultra commercial]] accidentally evokes this trope. In some of those shots, those little pink Duracell Bunnies look more like a mass of squirming maggots.
* There's a [[http://www.youtube.com/watch?v=1YHY0gGkXkQ Prius commercial]] that centers on a human made out of dozens of tiny humans. That "people person" gets out of bed, brushes its "teeth," etc.
* A public service announcement from the [[http://www.aphis.usda.gov/wps/portal/aphis/home/ USDA APHIS]] regarding accidentally bringing in invasive species was spoken by a man made out of various insects wearing gentlemanly clothes. He talks to the camera about his desire to spread himself elsewhere, then lifts up an arm and disperses the insects it's made of. This was intentionally played for creeps. He's basically the AffablyEvil spokesman for their "Hungry Pests" campaign.

[[folder:Anime & Manga]]
%%* Beelzebub in ''Manga/SixSixSixSatan''.
* Done in the most {{Squick}}tacular way possible in ''Manga/ApocalypseNoToride''. When the four juvenile delinquents escape from the frenzied prison into the zombie-filled streets of the city, they discover to their horror that the [[ThatsNoMoon mountain in the middle of the street is actually a towering mound made of the rotting corpses of the undead]], with a [[http://mangafox.me/manga/apocalypse_no_toride/v01/c003/43.html stark-naked figure sitting on the very top like a macabre throne.]] Then the mound starts [[http://mangafox.me/manga/apocalypse_no_toride/v02/c004/13.html moving.]]
* Borgir Bor from the ''Manga/{{Bastard}}'' anime/manga series.
* ''Manga/{{Berserk}}'': The Godhand do not have bodies that exist [[LayeredWorld in the material realm]], so when they want to affect things they need to take preexisting materials to make bodies from: Slan once made a body from troll guts and Conrad made one from a mass of rats.
* Gambon's mooks in ''Manga/FistOfTheNorthStar'' have speciality called the Centipede Fighting, where they hop on each others shoulder to form, well, [[ExactlyWhatItSaysOnTheTin centipedes]].
* In chapter 24 of ''Manga/FrankenFran'', [[spoiler: The WanderingJew]] shows up. Despite being immortal, his original body except for his skeletal structure has long since rotted away. His curse of immortality solved the problem by constantly summoning ''[[BodyHorror insects to replace his body]]''. He's essentially an undying skeleton with bugs for muscles and organs. [[spoiler: Amazingly enough, this chapter actually has a happy ending for the poor guy.]]
* Dokubachi in ''Manga/GetBackers'' is the Bee that Walks (and flies and philosophizes and [[OverlyLongGag uses ki attacks...]]) whose body is a bizarre, super-specialized honey comb that gives him all manner of bee-related abilities. Unusually for this trope, though, his final form looks [[BishounenLine completely human.]]
* The "[[OurZombiesAreDifferent Carriers]]" from ''{{Manga/Infection}}'' are basically colonies of maggots nesting within corpses of their victims, multiplying in such numbers that they burst out whenever the corpse opens its mouth. The problem only gets worse when they [[spoiler: start growing in [[FromBadToWorse ''size'']] as well.]]
* [[BigBad Naraku]] from ''Manga/InuYasha'' is composed of a giant, writhing mass of {{youkai}}, most of which are a mixture of snakelike, bug-like, and slimy in nature.
* ''Manga/JoJosBizarreAdventure'':
** Mrs. Robinson in ''Steel Ball Run'' (a ''man'' with a GenderBlenderName), supposedly was killed by men and hung out on a cactus only to revive. Similar to Shino, he used his body to store various insects which he could control. What is ''really'' creepy is that his power didn't stem from a Stand -- almost as if it was entirely fuelled by some kind of horror propane.
** F.F. from Part 6 is an even straighter example, being a mass of plankton that gained sentience and Stand powers, and later took up residence inside the corpse of a young woman so that she could join the heroes.
* In ''Manga/KingOfThorn'', the Medusa manifestation of [[spoiler:Peter Stevens]]'s psyche takes on this form.
* ''Manga/{{Naruto}}'':
** Shino Aburame and the rest of the Aburame clan, who while not made of bugs, house swarms of energy-draining beetles in their bodies since shortly after their birth, perhaps even more disturbing than simply being composed of the insects -- in short, they are basically human hives. A "[[SelfDuplication Bug Clone]]" technique also exists, in which the user creates a clone of himself out of those beetles, more true to this trope.
** [[spoiler:Orochimaru's ''true'' true form (yeah, he seems to have a lot of those) is that he's made of snakes, while being a giant snake himself. What do the snakes look like? Well, they certainly don't do anything to take away his reputation as a creepy boy watcher.]] Even before that was revealed, it was evident he was made of [[spoiler:snakes]] when he got cut in half and had them spring out of his halves to pull them together.
** Tsunade's Summon, Katsuyu the Slug, could dissolve into many smaller slugs, each of which talks and behaves like the original.
* Tommyrod from ''Manga/{{Toriko}}'' gives off this vibe, but is actually an aversion, as he is not literally ''made'' of insects. He just stores eggs in his esophagus and vomits the newly hatched bugs at the enemy. [[{{Squick}} Somehow that's even more disturbing than the alternative.]]
* Zazie the Beast from the manga version of ''Manga/{{Trigun}}''. In a metaphysical sense, yes, Zazie is "the worm who walks," but both of its bodies are perfectly normal humans. Zazie's ''mind'' is made of insects -- it's the current interactive hub for a HiveMind of the native sandworms.

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering'' has Mindleech Mass from the ''Ravnica: City of Guilds'' expansion. It's hard to see the individual leeches at card size, but [[http://www.wizards.com/Magic/Magazine/Article.aspx?x=mtgcom/arcana/914 when you look closer...]]

[[folder:Comic Books]]
* In ''ComicBook/TheSavageDragon'' comic, one of the supervillains is Horde, a body possessed by worms. It's later revealed that this is the wizard Fon~Ti (who granted Mighty Man his powers) who was taken over by one of Mighty Man's enemies, the Wicked Worm.
* In one of his earlier adventures, John Constantine, ''ComicBook/{{Hellblazer}}'' fights the hunger demon, Mnemoth, who manifests as a swarm of flies forming the shape of a giant fly. A similar creature, shaped like a man, appeared in TheMovie, but was not identified by name.
* ''ComicBook/SpiderMan'':
** The one-shot villain [[http://www.marvunapp.com/Appendix3/thousandkingcarl.htm The Thousand]] was made of an army of spiders that jumped from body to body.
** So was Ms. Arrow, "The Other".
* ComicBook/SheHulk also fought a similar villain, [[http://www.marvunapp.com/Appendix/cockrchs.htm Cockroaches!]]
* The first storyline of the Marvel comic spinoff series ''Force Works'' had the alien Scatter as the enemy. The Scatter resemble armored humanoids, [[spoiler:but as US Agent discovers, they're actually a swarm of sentient insects controlling the armor. It gets worse when he describes how he found this out, he was watching the Scatter climb out of the armor and eat the nearby civilians alive!]]
* ''ComicBook/ImmortalIronFist'': The character "The Bride of Nine Spiders", who, when she lifts up her {{stripperiffic}} outfit, reveals a mass of rotted, webbed flesh swarming with spiders that she can use to ZergRush her enemies. She's an unusual DarkIsNotEvil example of this, as she's a neutral-to-good PerkyGoth. Still not somebody to upset, though.
* And [[https://en.wikipedia.org/wiki/Swarm_%28comics%29 The Swarm,]] a [[StupidJetpackHitler Nazi]] scientist made of [[BeeBeeGun bees]]. Marvel loves their worms that walk.
* The ''ComicBook/BirdsOfPrey'' foe Entity was a nanobot swarm that consumed an industrial spy and maintained his basic humanoid shape.
* This was the first enemy of Vicki Montesi and the rest of the ''ComicBook/{{Darkhold}}''.
* ''Daniel X: Alien Hunter'': Played straight with Number 7, a human-alien being made up of a colony of ants. Not only was he partially responsible for the deaths of reality warper hero, Daniel X's, family, he also is the grandmaster of an interplanetary game where alien hunters kill innocent aliens for sport, resulting in the extinction of a peaceful, furry species whose culture is based on color. The utter subversion comes from Kilgore, who happens to be Number 7's "son". Much to his "father's" chagrin, Kilgore is a sweet, loving, trusting, and very geeky alien who becomes fast friends with Daniel X. When he "dies" by being reabsorbed back into his father, this unleashes Daniel X's berserk button, and he kills Number 7 by releasing a potion that disrupts the pheremone bonds the ants use to communicate in his body.
* ''ComicBook/{{Bone}}'': [[spoiler:The Hooded One turned out to be a woman who was [[HalfTheManHeUsedToBe cut in half]] then had her body put put back and held together by the Lord of the Locust's insects.]]
* The second ''ComicBook/XForce'' once met a "spectre of death" who looked like a giant monster made up of worms and maggots, with some skulls and bones thrown in as well.
* The Purple Ants in Jon Lewis's ''ComicBook/TrueSwamp'' kill a man and use his skeleton as a framework to become one of these.
* Murder in ''Hoax Hunters'' is something like this. He was an astronaut whose consciousness was split among a murder of crows when he died; the crows now share a hive mind and inhabit a space suit.
* In ''[[Comicbook/CountdownToFinalCrisis Countdown: Arena]]'', there's an AlternateUniverse version of Comicbook/BlueBeetle called the Scarab, who is a vaguely humanoid mass of blue scarabs. It eats its opponents, sometimes from the inside. Oddly for such a NightmareFuel creature, it's supposed to come from the FunnyAnimal world of [[Comicbook/CaptainCarrotAndHisAmazingZooCrew Earth-26]].
* Shinomura from the ''Film/{{Godzilla 2014}}'' tie-in comic ''Godzilla: Awakening'', consists of a mass of much smaller, single-celled organisms.
* The Shredder was killed in the first issue of ''ComicBook/TeenageMutantNinjaTurtlesMirage''. Every subsequent appearance is actually a colony of worms that were scientifically and magically conditioned to take on the mind and physical form of whoever they ate.
* ''ComicBook/{{Zombo}}'': Zombo at one point has to go up against "[=ZomBee=]", who is a giant mass of [[BeeAfraid flesh-eating bees]] in the shape of a zombie.
* ''ComicBook/{{Vampirella}}'': A recurring trend in the Dynamite series:
** The giant worm god Yad-Ath Yermellus manifested itself as a swarm composed of thousands of worms during a BattleInTheCenterOfTheMind.
** The resurrected [[spoiler:Von Kreist]] appears as a giant made of human ''skeletons'' in another mind sequence.
** The demon Botis appears before a Vatican strike team in the physical world made up of hundreds of dead rats.

[[folder:Films -- Animation]]
* In Hayao Miyazaki's ''Anime/PrincessMononoke'', a demon in the beginning appears as a giant, moving mass of worms. [[BodyHorror You don't want to touch it.]] [[spoiler:Technically, all demons are forest gods corrupted and covered with the snake/worm things. May still apply though, since the things ''almost'' seem to compose the body of the demons]].
* ''WesternAnimation/TheNightmareBeforeChristmas'': Oogie Boogie, the only inhabitant of Halloweentown who though comedic is outright evil instead of just playfully scary, is made of sackcloth sewn together over thousands of bugs (and one snake!).
-->'''Oogie Boogie:''' My bugs! My bugs! My bugs...
* PlayedForLaughs instead of scares in ''WesternAnimation/FindingNemo'' with the [[http://www.youtube.com/watch?v=Le13by2WM70 school of fish that assembles itself into various shapes]].
* One of the pink elephants from the "Pink Elephants on Parade" sequence in ''Disney/{{Dumbo}}'' is made up of multiple elephant heads piled up to form limbs and a torso, with three heads on top.
* In ''WesternAnimation/{{Coraline}}'', [[spoiler:the Other Bobinsky in his second appearance consists of nothing more than rats that have infested his old clothing.]]

[[folder:Films -- Live-Action]]
* The Ra'azac in the [[TheFilmOfTheBook movie version]] of ''Film/{{Eragon}}'' are composed of a variety of vermin and one eyeball.
* A character in the film ''Film/PrinceOfDarkness'' delivers an unpleasant message to the protagonists before falling apart and collapsing into a heap of large black beetles.
* In ''Film/{{Constantine}}'', the title character is attacked by a demon made entirely out of various bugs (and at least 1 crab). Even its face, with nose and mouth and eyes. In a bit of hilarity, it's killed by being run over and splattered all over a car. Let's hope that driver has good wind-shield wipers.
* When the Film/{{Candyman}} opens his coat, he's revealed to be little more than a skeleton wreathed in the many thousands of bees that killed him.
* [[Film/GodzillaVsDestoroyah Destroyah]] is a truly massive example, although as its component creatures are microbes, it appears solid to the naked eye.
* In ''Film/FrightNightPart2'', the undead... thing... Bozworth spends most of the film catching, identifying and then ingesting insects. When finally killed, he bursts open to reveal he's pretty much skin, skeleton, and lots of squirming little bugs.
* Inverted in ''Film/TheHumanCentipede''. There, you have a large borderline insectoid made up of three humans.
* The Creator/{{Syfy}} [[Film/SyfyOriginalMovie film]] ''Film/TheBoneSnatcher'' has a swarm of demonic ants that achieve a rudimentary humanoid form using the bones of people they've eaten.
* Chitti from ''Film/{{Endhiran}}'' starts out as your standard Terminator robot with Matrix effects, then he makes magnetized copies and becomes a macro-nanobot snake made of guys, taking the forms of a sphere, a cobra, and a giant, among others.
* Reedman from ''Film/TransformersRevengeOfTheFallen'' actually transforms from thousands of tiny sphere-like Decepticons (described by Wiki/TFWikiDotNet as "Anime/{{Bakugan}} balls") puked up by Ravage.
* ''Film/Critters2TheMainCourse'' has the ever-hungry alien pests gang up into a huge mouth-covered ball that rolls over a victim and leaves a stripped skeleton behind.
* One scene in Disney's ''Film/{{Mars and Beyond}}'' shows a pursuing alien transforming from a swarm of insects while chasing a secretary.

* ''Literature/{{Animorphs}}'':
** The Nesk are ants that form themselves into larger bodies, as per this trope. Given that the same book includes a HistoricalInJoke about broccoli being introduced from an alien world, it's entirely possible that normal ants on planet Earth are the descendants of the alien Nesk. This is, in fact, WordOfGod. Kinda puts the fact that ants were the morph that terrified the protagonists more than any others in a new light, eh?
** Also the Valeek in the first ''Megamorphs'' book was a tornado made out of alien bugs.
* Inverted in Creator/CliveBarker's ''In the Hills, the Cities'', in which tremendous walking figures are constructed out of ''people''. To put this in perspective, the constructed being's "teeth" are made from children's shaved heads.
* The flying nanobot swarms in the Creator/MichaelCrichton novel ''Literature/{{Prey}}'' act like a computerized version of these -- they even eat carrion, as per standard maggot behavior. As their intelligence develops through the course of the book, they learn to mimic human shapes, colors, and eventually ''speech''. Turns into full body horror, when the main character discovers that the swarm has enveloped and taken over his wife. However, using an electro-magnet, the swarm dispell from the body, revealing his real wife (now a shriveled skeleton) who is still alive. She is able to relay her last words before the device breaks and the nanobots overtake her body again.
* Ygramul the Many of ''Literature/TheNeverendingStory'' by Creator/MichaelEnde, is a gestalt collective of toxic flying "things" that clump together in whatever arrangement suits their purpose best, from a giant spider-thing to a massive disembodied hand. Her deadly poison grants the dying victim the ability to teleport.
* In Creator/NeilGaiman's ''Literature/{{Coraline}}'', Mr. Bobo is a trainer of mice. In the Other Mother's world, The Other Bobo is a being made of rats. In TheFilmOfTheBook, the Other Bobinsky ends up turning into this as GlamourFailure sets in:
-->'''Coraline:''' You're just a copy she made of the real Mr. B.\\
'''The Other Bobinsky:''' Not even that, anymore.
* In ''The Green Brain'' by Frank Herbert, humanity has reduced nature to just a few zones in the Brazilian rainforest. Nature fights back by evolving a race of bugs that can, in large quantities, imitate human beings. The story opens with one such Worm That Walks managing to con its way past the border guards so that it can enter and attempt to infest a clean zone.
* The priest of the [[NamesToRunAwayFromReallyFast God of the Lost]] in Creator/StephenKing's ''Literature/TheGirlWhoLovedTomGordon'' is composed of innumerable wasps endlessly crawling over a yellowing, decayed human skeleton. [[spoiler:The God of the Lost itself is also one of these, taking the form of a black bear whose innards are mostly comprised of wasps.]]
* Played straight in Creator/DeanKoontz's ''Seize the Night'', by the ''things'' that came back through the egg room in Hodgson's suit. They may have come from an AlternateUniverse, or from the future via TimeTravel, neither of which is a comforting thought.
* ''Inside Straight'', the latest novel in the ''Literature/WildCards'' series, features a rare heroic version of this trope, one Jonathan Hive. He appears utterly human until he disperses into a cloud of bright green wasplike motes; he can also detach as few as one at a time, and even tends to have a few wandering about misplaced.
* ''Literature/UnLunDun'':
** While not a villain, this contains a passing reference to a man made of bees arguing with a bear.
** And Skool, who is a bunch of fish inside a wetsuit. He's also a rare heroic version of this.
* The "throng-bear", an unintelligent variant from ''Literature/IronCouncil''.
* ''Literature/{{Discworld}}'':
** In ''Discworld/AHatFullOfSky'', young witch Tiffany dances with a human-shaped swarm of bees. This swarm is perfectly benign though, and it is considered a promising sign that Tiffany, unlike most people, isn't afraid of them.
** A more comical example from ''A Hat Full of Sky'', reappearing in the subsequent book ''Discworld/{{Wintersmith}}'', is [[TotemPoleTrench the Nac Mac Feegles disguising themselves as a human (singular) by stacking themselves up inside several stolen items of clothing]].
** Borrowing a swarm of bees is a CrowningMomentOfAwesome for Granny Weatherwax in ''Discworld/LordsAndLadies''.
** A minor version of this occurs in the character of Hex in the Unseen University: A "computer" controlled by the ant colony living inside it. A similar type of machine can be seen in the Glooper in ''Discworld/MakingMoney'', although that one is controlled by water and tides and the economy.
* The Vermiform in Steph Swainston's ''Castle Circle'' series is one of these.
* An assassination attempt in ''[[Literature/TheMirrorOfHerDreams Mordant's Need]]'' by Stephen Donaldson features human skins full-to-bursting with cockroach-like insects that puppet the skins and then break out of their husks in order to devour their new victims.
* Creator/HPLovecraft:
** One common interpretation of the ending of "The Festival," though it could just as easily refer to a maggot-infested corpse, or a single huge worm.
--->''Wisely did Ibn Schacabac say, that happy is the tomb where no wizard hath lain, and happy the town at night whose wizards are all ashes. For it is of old rumour that the soul of the devil-bought hastes not from his charnel clay, but fats and instructs the very worm that gnaws; till out of corruption horrid life springs, and the dull scavengers of earth wax crafty to vex it and swell monstrous to plague it. Great holes secretly are digged where earth's pores ought to suffice, and things have learnt to walk that ought to crawl.''
** In ''Literature/TheDunwichHorror'', the invisible monster, while made visible for enough time to [[EldritchAbomination make a hapless witness go mad with fear]], is made up entirely from either worms, or, as the character puts it, "squirmin' ropes" or "sep'rit wrigglin' ropes pushed clost together", [[{{Squick}} all of slime or jelly]].
* One of the heroes of the grail in Eric Nylund's ''Literature/AGameOfUniverse'' is a colony of insects which walks around in humanoid form, relatively.
* In ''The Talismans of Literature/{{Shannara}}'', Walker Boh is attacked by TheFourHorsemenOfTheApocalypse (well, actually monsters who have taken the form of TheFourHorsemenOfTheApocalypse). While Famine, War and Death are humanoids, Pestilence is just a swarm of infection-spreading insects moving about in a vaguely humanoid shape.
* The ''Literature/FelixCastor'' series features loup-garous, human ghosts that manage to force their way into animal bodies and reshape them into human flesh. The first novel has Felix facing down a crime boss's pet were; when he manages to exorcise the ghost steering the body, [[spoiler:it collapses into a swarm of rats]]. Even Felix is freaked out.
* A benign example from ''Swimmy'' by Leo Lionni featured fish being eaten by a larger fish. They formed their school into the shape of an [[AlwaysABiggerFish even bigger fish]] and chased it off.
* The ''Literature/RavnicaCycle'' of ''TabletopGame/MagicTheGathering'' novels feature the Lupul, a shapeshifter. Its true form is a writhing mass of worms that devours people in order to steal their forms.
* ''Kingdoms of Light'' by Creator/AlanDeanFoster features Khaxan Munderucu, an incredibly powerful giant evil spellcaster. He's really twenty-two goblin mages in a giant TotemPoleTrench, all combining their magic.
* In Niven and Barnes' ''Literature/TheBarsoomProject'', the sins of humanity make an appearance in the Fimbulwinter Game as a swarm of monstrous insect-like vermin, which assemble themselves into four giant humanoid figures to put HumanityOnTrial.
* This is taken UpToEleven in the SequelSeries to ''Literature/TheSpiderwickChronicles,'' where [[spoiler:a group of ''dragons'' have become this over the centuries as their tails have become stuck together by the filth surrounding them. TheHero defeats them by cutting apart the muck binding their tails. Since they've been used to existing as one creature for so long, they become confused after their separation and are easier for the helpful giants to defeat. These dragons were based on the legendary "Rat King" (see the section for [[AC:{{Mythology}} and {{Religion}}]] below), and in homage to this inspiration, the third book in the SequelSeries is called ''The Wyrm King.'']]
* In ''Literature/TheMoteInGodsEye'', a bunch of "Watchmaker" Moties packed inside a spacesuit manage to briefly pass for human, with the help of a severed head.
* ''Literature/TheDresdenFiles'' gives us the "rawhead" in ''Cold Days''. It is a huge beast, made out of the discarded bones and flesh of slaughtered cattle and such, with no skin. The detailed descriptions are... horrific.
** In ''Skin Game'' we see Tessa can assume this form, and she uses it to great effect in one of [[NightmareFuel the most horrific scenes]] [[MindRape in the series.]]
* Vaashka and their regressed cousins Tathas in ''Literature/JewelsOfTheDragon''.
* Sort of in ''Literature/TheBookOfLostThings''. [[spoiler:When the Crooked Man tears himself apart, bugs and worms fall out.]]
* In ''Literature/ThoseThatWake'', [[spoiler:Man in Suit has slimy, wriggling things inside of him; it's unclear as to whether they inhabit him or if they're what he's made of, or if it's all just part of Mike's dream]].
* ''Literature/StarCarrier'':
** ''Earth Strike'' has the nonsentient "shadow swarmers" of Eta Boötis IV, a colony creature that separates itself into thousands of smaller creatures that resemble a cross between a leaf and a sand dollar. The smaller creatures range across hundreds of kilometers in search of food ([[AlienLunch carbonaceous rock formations]]), then alert each other with ultrasound when they find some.
** ''Center of Gravity'' introduces the H'rulka, 200-meter {{Living Gasbag}}s that live in the atmospheres of hydrogen-helium gas giants. They're sapient, and their name for themselves roughly translates as "All of Us".
* In ''Literature/DocSidhe'', Duncan Blackletter's construct Adonis turns out to be composed (and animated) by a bunch of worms over an oversized humanoid skeleton.
* The assassin at the end of Iain M Banks [[NightmareFuel/TheCulture Look to Windward]] is a swarm of nanotech bugs.
* In ''Literature/TheNekropolisArchives'', Molog, the Demon Lord of Insects, has a body made out of millions of insects. The Watchers also tend to manifest in the form of insects, and gather together swarms of these component insects when they wish to assume larger forms.
* The needle monsters (and people) in ''Literature/EdenGreen''.
* The VillainProtagonist team in ''The Goblin Corps'' by Ari Marmell has repeated dealings with worm monsters that infest and consume anyone they come in contact with, and take humanoid forms to attack when they aren't a raw swarm. Eventually it's revealed [[spoiler: that when [[BigBad Morthul]] took over his kingdom, he turned the old king into this out of spite. The worms have been multiplying for centuries, underground and unnoticed, and they still ''hate'' Morthul for what he did to them.]]
* ''Literature/{{Edgedancer}}'' (a novella of ''Literature/TheStormlightArchive''): Lift discovers that Dysian Aimians are creatures composed of hundreds, if not thousands of tiny crustaceans called cremlings, which the HiveMind breeds to fulfill a specific purpose, like storing memories or seeing, so that they might masquerade as a human. While it takes a great deal of effort for them to effect even a basic human shape, the fact that most of the Dysians are hundreds of years old means that they have a lot of practice, and they're scarily good at it.
* In "The Tractate Middoth" by [[Creator/MontagueRhodesJames M R James]], the ghost is implied to be a human spirit possessing a horde of spiders and shaping a human form out of them and their webs.
* In ''Literature/{{Worm}}'', the protagonist, who has the power to control insects, surrounds herself with bugs to intimidate her opponents into thinking she has transformed into a giant human-shaped swarm, and makes the insects around her buzz and chirp whenever she talks to complete the illusion of a giant humanoid insect swarm. She also picks up a habit of using swarm decoys, masses of insects in a roughly humanoid form that looks exactly like she's pulling the previous trick.

[[folder:Live-Action TV]]
* ''Series/BuffyTheVampireSlayer'':
** Norman Pfister from the Season Two episodes "What's My Line, Part One" and "What's My Line, Part Two." He's a group of maggots that can appear like a man (but not for very long, as he starts to go all UncannyValley). Xander and Cordelia manage to kill him with [[CrowningMomentOfAwesome a bucket of glue]].
** The Swell's combined form in the Season Eight issue "Swell" (made up of all the individual Vampy Cat Play Friends).
* ''Series/{{Reaper}}'' had an episode with a woman made of bugs.
* In the third ''Series/{{Lexx}}'' movie, "Eating Patterns", the crew of the Lexx stumble onto an isolated colony of scavengers who are infested with wormlike parasites. The Queen Worm, which is roughly the size of a SeaMonster, creates fake people to act as its eyes and ears on the rest of the colony.
* ''Series/DoctorWho'':
** The [[LivingShadow Vashta Nerada]], who are normally a mass of tiny ''things'' that live in the shadows and devour meat. If they get inside a person's sealed spacesuit, though, the person will be devoured to the bone, and the Vashta Nerada will animate the spacesuit.
** Davros's servant Colony Sarff is a collection of snakes coiled around each other to form the shape of a man. While there is one snake much larger than the others that forms the core, they are apparently a "democracy".
* ''Franchise/PowerRangers'' has done this to spice up the MonsterOfTheWeek.
** In ''Series/PowerRangersInSpace'', thousands of all-devouring monster termites could come together to make a monster, who was pretty hard to damage because hitting him just knocked loose a few of the pests.
** Also, Craterites -- holo-{{Mooks}} used in training simulations -- came to life and terrorized town (and it ''wasn't'' the usual villains' doing.) Eventually, they came together to make a humanoid mishmosh of themselves that was HumongousMecha scale.
* In ''Series/{{Andromeda}}'', a guest turned out to be composed of nanobots.
* A ''Series/{{Farscape}}'' episode has a colony of horrible spider-like things that can do this [[spoiler:and impersonates one of the regular cast]].

[[folder:Music Videos]]
* The MusicVideo for [[http://uk.youtube.com/watch?v=tFJd9n8X9DI&feature=related "The Beeching Report"]] by [=iLiKETRAiNS=] features a colony of insects taking on human form and battling Dr. Beeching himself. The trope is then subverted in that Beeching is unafraid of the colony (which represents railway workers laid off because of the Beeching axe) and simply crushes the insects.
* The music video for Music/{{Rammstein}}'s Links 2-3-4 has a horde of giant insects coming to destroy some ants. The ants then eat the giant insects, and then ''dance on their corpses''.

[[folder:Myths & Religion]]
* Downplayed example: Azhi Dahaka, a three-headed dragon associated with the Zoroastrian apocalypse, has scorpions instead of blood.
* Medieval European folklore gives us the "Rat King" (as well as being the namesake of [[RatKing a trope]]), a particularly nasty creation consisting of a swarm of black rats joined together at their tails by their sticky urine and feces. It's basically a big ball of vermin and filth. Some taxidermy fabrications exist, but there's no record of it ever actually being seen. [[ScienceMarchesOn Actual study into rats has proven such a creature could never exist]], since real rats are actually very clean and well-groomed animals that would never get so filthy as to be able to get tangled up. That said, rare occurrences of "squirrel kings" have been found and documented.

[[folder:Tabletop Games]]
* ''TabletopGame/CallOfCthulhu'': The name first appeared in the ''Shadows of Yog-Sothoth'' adventure "The Worm That Walks" as the name of a monster that was '''not''' made out of worms. An example called "the Crawling One" appeared in the original Chaosium version, in the ''Shadows of Yog-Sothoth'' adventure "The Watchers of Easter Island". It was based on a creature that appeared in the [[Creator/HPLovecraft Lovecraft]] story "The Festival":
-->''[H]appy is the tomb where no wizard hath lain, and happy the town at night whose wizards are all ashes. For…the soul of the devil-bought hastes not from his charnel clay, but fats and instructs the very worm that gnaws; till out of corruption horrid life springs, and the dull scavengers of earth wax crafty to vex it and swell monstrous to plague it. Great holes secretly are digged where earth’s pores ought to suffice, and things have learnt to walk that ought to crawl.''
* ''TabletopGame/DungeonsAndDragons'':
** In the ''TabletopGame/EpicLevelHandbook'', and ''TabletopGame/{{Pathfinder}} Bestiary (part II)'', there is a monster called "Worm That Walks", a dead spellcaster that has become the HiveMind for an army of worms -- gaining insect-related powers and a great deal of additional resilience. Usually it's the evil ones that choose this method of life after death. Players can actually turn themselves into a Worm That Walks, although it carries a chance of failing and just leaving them as a rotting corpse.
** 3.5 also, in its ''Elder Evils'' sourcebook, featured a unique Worm That Walks, a really ''big'' one: Kyuss, the evil god of "green worms that eat you from the inside out, then turn you into a super-powerful zombie under their control." And he is made of those worms. There is also a whole 20-levels long campaign outline in that book called Age of Worms. Guess who's the ''[[BigBad Big Bad Boss]]'' of that one. Said campaign was published in its entirety in ''Dungeon'' magazine before ''Elder Evils'' came out.
** Also in the 3rdEdition Monster Manual 2, the Leechwalker. A bloated bipedal monster made of millions of leeches that have formed a hive mind. And it can drain a person of all their blood in seconds.
** The Worm that Walks shows up again in 4th Edition as the "Larva Mage."
** The Larva Mage has some cousins, too. The Larva Assassin is the soul of a PsychoForHire given form through a swarm of hornets and centipedes. Larva Snipers were {{Cold Sniper}}s (or at least sadistic marksmen) in life, now an undead composed of wasps. Larva War Masters were {{General Ripper}}s, {{Blood Knight}}s and similar depraved, insane warriors in life, their souls called back and thrust into undeath as the HiveMind of a swarm of carnivorous beetles.
** The [[CallAPegasusAHippogryph Lamia]] from 4th Edition is an evil fey creature which is a seething swarm of scarab beetles wrapped around the flesh-stripped bones of a powerful fey creature. Many lamias take the form of eladrin that they've hollowed out this way.
** The great-granddaddy of all these ''D&D'' Worms That Walk was the cifal, a rather forgettable colonial-insect monster from the 1E ''Fiend Folio''. ("Cifal" is actually [[FunWithAcronyms an acronym]] that stands for "Colonial Insect Formed Artificial Life".) Whom they just dumped into the recent version of ''TabletopGame/GammaWorld'', along with [[OurMonstersAreWeird all the other effed-up ''D&D'' monsters]]
** A rare Good-aligned version appears in, of all places, the EldritchAbomination-filled ''Lords of Madness'' 3.5 sourcebook, with the silthilar — sentient swarms with just a touch of the MadScientist when they fuse into their solid form.
** The ''TabletopGame/{{Ravenloft}}'' setting has maggot golems. While disgusting, these golems have a clever design. The living maggots that make up the golem's body continually grow into flies (which swarm around the golem, constantly) and so long as the maggots and flies can feed on rotted meat (usually provided by creatures it kills) the flies lay eggs on the golem, which hatch more maggots, creating a continual cycle that give the golem a powerful regenerative ability.
** Roach thralls in ''TabletopGame/D20Modern''.
** Yet another version from 3.5, in the Exemplars of Evil book (for designing villains) is the former archmage of the Tolstoff family who researched the deceased god the Worm That Walks, learned evil spells, acquired foul magic items, and made pacts with dark entities. Eventually the deity noticed him and "rewarded" him with its filthy blessing, an attack of ravenous worms and maggots that ate his physical body but which absorbed his soul. Sealed in a vault within the catacombs beneath the mansion by his horrified daughter, he then proceeds to whisper and corrupt his grandchildren into evil servants who will stop at nothing to free him from his tomb. (He would later appear as TheDragon in the scenario for Kyuss (see above) in ''Elder Evils''.)
** Third-Party publisher Dreamscarred Press has released a sourcebook called "Phrenic Scourges", who embody this trope. They're a hive-mind of worms that will be happy to convert you into fawning slave, or the next generation of worms, or both!
* In ''TabletopGame/{{Pathfinder}}'', the [[DemonLordsAndArchdevils Archdevil]] Baalzebul is a FallenAngel whose body was stripped away and transformed into a cloud of flies by Asmodeus.
* ''TabletopGame/WerewolfTheApocalypse'': The Hollow Men, a breed of fomori (humans under the thrall of DemonicPossession). The Hollow Men specifically are humans who were killed and whose bodies were mostly emptied out (hence the name), the insides replaced by a swarm of small animals controlled by the demonic spirit in question. Doesn't have to be insects/arachnids; reptiles and rodents are also popular choices. They're capable of speech and can ''try'' to pass themselves off as fully human, but generally, even other fomori find them creepy as hell.
* The Azlu in ''TabletopGame/WerewolfTheForsaken'' are spirit-like creatures that can do something similar. In their case, only one of the spiders is really "them", so they escape by using the weight of numbers -- the odds of the real one getting killed are incredibly small. The Beshilu of the same game are similar. They're rats, not bugs, but can hollow out human bodies and control them like the Fomori mentioned above.
* One of the kinds of monsters in ''Tabletopgame/LittleFears'' is worms. They gather into groups and mimic the forms of children. The problem is that they can't mimic eyes, so they have to actually kill children and steal their eyes to pull it off convincingly.
* ''TabletopGame/Warhammer40000'':
** The Slaugth from the RPG ''TabletopGame/DarkHeresy'' are an ENTIRE RACE of these. The trope is even mentioned by name.
--->''"The worm that walks has come for us all" Found carved into a bulkhead, Watchpost Hazeroth/Sentry 17. All hands lost, attacker unknown. 123.M40''
** Meanwhile, the Black Library novel ''Death of Antagonis'' contains a truly disturbing inversion, when a particularly nasty Chaos Daemon manifests itself in the form of a gigantic worm made out of the bodies of every human being on the title planet.
* The ''TabletopGame/MutantsAndMasterminds'' setting TabletopGame/FreedomCity features a villain called The Collective, which follows this trope. As every other character in that entire setting, he is a CaptainErsatz of an existing comic book character, probably Marvel's Swarm (see comic section above)
* Wyld mutants with the "Hive" abomination in ''TabletopGame/{{Exalted}}''. One rank in "hive" and they have a beehive or snake nest somewhere on their bodies. Two ranks in "Hive" and the nest expands to include the rest of them.
* Worm Wraiths in ''TabletopGame/{{Rifts}}: New West'' are evil ''Cowboy'' Worms That Walk. Also invoked by the [[HorsemenOfTheApocalypse Horseman]] Pestilence, which is actually a giant walking skeleton covered in bugs instead of flesh and skin.
* In ''TabletopGame/EclipsePhase'' one of the many Synth bodies resembles a swarm of robotic bees. They can move as a regular swarm, or combine into a roughly human-shaped mass. They're also fully playable, and far more affordable then those based around OrganicTechnology.
* One of the possible character origins in ''TabletopGame/GammaWorld''. Depending on your primary origin and your secondary origin, you could be anything from a horde of cockroaches, to a [[GreyGoo mass of nanomachines]], to a ''[[CuteKitten horde of sentient, hive-minded kittens]]''.
* ''TabletopGame/WarhammerFantasy'' had one introduced in the new [[DemBones Tomb Kings]] army book. Apophas of Numas was a Nehekharan prince who murdered his family, and was executed by being sealed into a coffin filled with Neheakaran Scarabs. His body was reduced to his skull, upon which a cursing rune was carved. In the Netherworld, he made a deal with the God of Death. He promised to bring him someone who was his equal to take his place. His soul was given command over the scarabs who ate him alive, and he scours the world for his equal. But, no two souls are truly equal, and he is damned to wander the world forever.
* The D20 campaign book ''TabletopGame/{{Grimm}}'' gave us this trope in the form of Rapunzel. Yes, that Rapunzel. Only this time around, her prince has passed away, her children are grown and she had nothing to do but return to the tower where she lived out the rest of her days. The tower, though, had developed intelligence and gotten lonely in her long absence and took measures to keep her there even after she died. Namely, having her corpse infested with a swarm of spiders that will kill and eat any who climb her hair to the tower. Keep in mind that the rules of the game are built specifically around children and boys are particularly drawn to the silky locks that still hang out the window. She's also one of the sample [=NPCs=] that made the transition when the game was converted to its own rules system.
* ''TabletopGame/ScarredLands'': One of the monsters described in the ''Creature Collection II: Dark Menagerie'' are vermin hosts, former human vagrants who were cursed by one of the evil gods who was angry that they happened to pray to another god other than him to let them live another day in their dismal squalor. From this DisproportionateRetribution he had various vermin (rats, roaches, leeches, spiders) burrow into their skin, giving them CursedWithAwesome powers as they are able to use their new abilities to control their own swarm of vermin, turn into giant anthropomorphic versions of those vermin, and disintegrate into swarms to help escape enemies or commit espionage (which the spider vermin hosts do most of the time). As a side note, they're able to reproduce TheVirus style by allowing one of their vermin to infect a person, whose whispers of power and whatnot usually cause them to accept them thereby summoning a larger swarm of that vermin which turns them into new vermin hosts while inheriting some of the memories of the previous ones. This is also {{squick}} because, mind you, the vermin are always moving under the host's skin to find more comfortable areas to rest. Remember one of those vermin are large rats!
* ''TabletopGame/EarthDawn'' 1st edition lists a magic spell called Wormskull that makes the caster's head appear as a skull made from worms, supposedly to impress and scare people.
* ''Carcosa: Weird Science-Fantasy Horror Setting''. The Unquiet Worms monster is a horrid collection of worms that takes a vaguely humanoid shape and walks like a man. They're created when a Sorcerer dies and the worms that eat his brain gain his knowledge.
* ''TabletopGame/{{Numenera}}'': Naiadans are a species of beings whose bodies are entirely composed of thousands of tiny creatures called dyremmi, all acting together to form a larger individual being. There are also naiadapts, the descendants of humans who modified themselves or who were modified to have colonies of dyremmi living in their bodies and acting as extensions of their beings. Both naiadans and naiadapts have the ability to alter their bodies and abilities by simply removing some of the dyremmi currently making them up and exchanging them for new ones carrying a desired trait, altering themselves by manipulating the balance of their component creatures. "Wild" dyremmi also exist, some of which are reported to have developed individual intelligence and see the naiadans and naiadapts as horrific conglomerations that must be destroyed to free their "enslaved" dyremmi.

* ''Toys/{{Bionicle}}'':
** Technically, Zaktan. When his old boss tried to vaporize him, he was somehow able to pull himself back together as microscopic "protodites". In this new, permanent state, Zaktan can easily avoid attacks by turning into an insect swarm; change the shape of body parts; heal damage by filling the gaps with Protodites; and engulf a foe in an attack that must feel like getting hit with thousands of needles. Zaktan himself calls it a curse however, as his voice now sounds like a crowd speaking; and whenever he wakes up he can feel his body shifting "where there once were tissue and solid metal".
** A heroic version shows up in the ''Legend Reborn'' movie. [[spoiler:TeamPet Click (a beetle) summons and teams up with a swarm of fellow beetles to form a giant warrior that makes the evil army figuratively mess their pants.]]
* The Vermillion Army in ''WesternAnimation/{{Ninjago}}''. Unlike the Serpentine, the franchise's other race of SnakePeople, they're made out of multiple snakes held together within their armor, and as such multiple warriors can combine together to form a larger being.

[[folder:Video Games]]
* ''Franchise/ResidentEvil'':
** The Leech Man from ''VideoGame/ResidentEvilOutbreak'' is a corpse controlled by many leeches (which have been mutated by the [[TheVirus T-virus]]) attached to him.
** The earlier game ''VideoGame/ResidentEvil0'' also has enemies known as "[[spoiler: Marcus]] clones" or "Leech Zombies". These are swarms of mutated leeches which cluster together into a vaguely humanoid form and can even take on the shape of their creator. They preceded and may have inspired the Leech Man.
** This also shows up in ''VideoGame/ResidentEvil5'' to a lesser extent. [[spoiler: Excella and at least two men become worm-people for a few moments then they just go straight to being masses of worms.]]
** ''Resident Evil 5'' was [[DummiedOut originally planned]] to have the [[http://residentevil.wikia.com/U-9 U-9]] enemy, a gigantic Worm that Walks. At 80 foot tall, it would have been the largest enemy in the series to date had it been included in the game.
** ''VideoGame/ResidentEvil6'' has an enemy that is made up of pieces of dead flesh that join together to walk towards the player; once shot, though, pieces start to fall off...but all the pieces just keep on coming for you until they decide to reform and start all over again.
* Ananzi, from ''VideoGame/TheBlackHeart'', is not quite one, but with the ease she produces spiderlings out of nowhere, she comes close.
* The Guy Made of Bees from the ''VideoGame/KingdomOfLoathing'', which is [[ExactlyWhatItSaysOnTheTin exactly what it sounds like.]] When you beat him, he drops a Guy Made of Bee Pollen. You can also pickpocket a handful of [[http://kol.coldfront.net/thekolwiki/index.php/Handful_of_bees them.]]
* The BigBad of ''[[VideoGame/SamAndMaxFreelancePolice Sam And Max: Season 1]]'', [[spoiler: magician Hugh Bliss]], turned out to have been a human-shaped sentient colony of bacteria in disguise.
* ''Franchise/{{Halo}}'' :
** The [[GiantMook Hunters]] are composed of hundreds of orange-red worms called Lekgolo. Plated armor protects these worms from conventional weapons and a high-powered energy cannon of doom deals with their foes, though even without all that gear, they were enough of a match for the Covenant's [[ProudWarriorRaceGuy Elites]] that they had to be [[DeathFromAbove orbitally bombarded]] to be forced to fall in line. Once a Hunter colony grows large enough, it splits into two separate ones that share a bond, becoming BashBrothers who go out on a RoaringRampageOfRevenge if one of them dies within sight/hearing of the other. Since the individual worms aren't advanced life forms in the same way humans and the other members of the Covenant are, they're also immune to direct infection from the Flood. That said, while an individual Lekgolo is rather dumb, the Hunters themselves are actually quite intelligent. The Hunters are also somewhat unusual in that unlike most examples on this page, they're simply PunchClockVillain-StarfishAliens, who are not especially malicious or sinister beyond being really good at killing you. In fact, when the Covenant breaks, many of the Hunters actually side with the human-friendly Elites.
** In fact, the Hunters are only one of the many gestalt types that Lekgolo can form. The gigantic [[SpiderTank Scarabs]] from ''VideoGame/{{Halo 3}}'' onward are partially comprised of a whole bunch of worms as well; the manual for ''VideoGame/HaloReach'' even implies that they are not so much true vehicles as much as massive suits of PoweredArmor for the Lekgolo. Case in point: In the level "The Covenant", one of the two Scarabs that drop from orbit rears up and roars, while in ''VideoGame/HaloReach'', one actually roars in pain when it's destroyed by [[spoiler:Carter]] ramming his Pelican into it.
* ''VideoGame/CastlevaniaDawnOfSorrow'':
** The boss of the NostalgiaLevel is Bat Company, a pack of red bats that assumes various forms as one. {{Dracula}} himself is often shown moving around as a pack of bats.
** Also the reoccurring Boss Legion is a giant Sphere of Zombies covering a giant monster. In ''VideoGame/CastlevaniaSymphonyOfTheNight'', it periodically sheds zombies that attack independantly.
* Arakune from ''VideoGame/BlazBlue'' fits this trope faithfully. What makes him horrifying is that he used to be human before a hideous accident, and his current form is very much a case of AndIMustScream.
* Beelzebub from both versions of the ''Franchise/ShinMegamiTensei'' games Raidou Kuzonoha is a massive fly concocted from a swarm of other flies. And incidentally, one of the best demon summons in the second game.
* In the PC Engine CD version of ''VideoGame/GoldenAxe'', [[https://www.youtube.com/watch?v=TX7WoSRHt3U Death Adder merges together from hundreds of snakes.]]
* All the enemies from the Subspace in the Subspace Emissary mode for ''VideoGame/SuperSmashBros Brawl'' are constructed of [[http://super-smash-bros.wikia.com/wiki/Shadow_Bug "shadow bugs"]] [[spoiler: extracted from Mr. Game & Watch.]]
* The Pain from ''VideoGame/MetalGearSolid3SnakeEater''. While not composed of bees, he is able to control bees by having them sting him until the bees think that he is one of them. To make matters worse, he grows, within him, [[BeeBeeGun Bullet Bees]]. These ones fly to your body and gnaw at your flesh slowly. And yes, he grows them '''within''' his body, launching them from his mouth. Keeping true to the trope, he can make a [[CoolButInefficient life-sized, fully voiced clone of himself]], made of -- you guessed it -- bees. Or they can become a full-sized, working, wood-and-metal Tommy gun (for which the science behind the trick isn't explained until two games later).
** [[spoiler: Organ-replacing Parasites]] in ''VideoGame/MetalGearSolidVThePhantomPain'' act as the game's {{Phlebotinum}}, leading to several characters being this to a greater or lesser degree, including [[spoiler: Skull Face, [[ArtificialZombie The Skulls]], Quiet, and Code Talker. It's even implied that the supernatural powers of the Cobra Unit, including The Pain, are the result of parasite therapy.]]
* Jalhalla in ''VideoGame/TheLegendOfZeldaTheWindWaker'' is a giant Poe made up of twenty smaller Poes and a mask that seems to either control or coordinate them.
* The very first boss of ''VideoGame/{{Metroid}}: [[VideoGame/MetroidOtherM Other M]]'' is a swarm of purple bugs that form a body around a larger bug that makes up the eye.
* Atticus Thorn, the BigBad of ''VideoGame/TheHauntedMansion'' video game.
* In ''VideoGame/{{Ys}} I and II'' and ''Ys Origin'', Vagullion is a demon composed of a swarm of bats.
* ''VideoGame/DarkCloud 2'' (Dark Chronicle) had the Rainbow Butterfly boss that split into different-coloured butterflies the PC had to sneak up on and swat to death.
* In a more spiritual way, Ermac from ''VideoGame/MortalKombat'' is this. He is the gathering of souls lost during Outworld's various wars, brought together to serve Shao Khan. As a result, Ermac never uses singular self-referential pronouns such as "I" or "me", instead opting for "us" or "we", in a sense allowing his body to speak on behalf of all the souls that he carries.
** D'Vorah, introduced in ''[[MortalKombatX MKX]]'' is a more standard sentient insect colony. She takes the form of a woman with buglike features (chitinous skin, compound eyes, etc). Since she's a walking hive, she refers to herself as [[ThirdPersonPerson "This One"]] instead of using singular pronouns.
* ''Franchise/{{Pokemon}}'':
** Drifloon and Drifblim in ''VideoGame/PokemonDiamondAndPearl'' are collections of wayward souls fused together into a form resembling a helium balloon and a hot air balloon, respectively. In the same games, there is Spiritomb, composed of 108 malevolent human souls bound to a (non-sentient) rock.
** ''VideoGame/PokemonXAndY'':
*** The [[OlympusMons Legendary Pokémon]] Zygarde is actually composed of many smaller green creatures known as Zygarde Cells (too small and weak to individually be called Pokémon), as well as other small creatures called Zygarde Cores, which serve as the "brains". The form Zygarde takes is actually determined by how many of the cells it has gathered to itself -- the serpent-like form encountered in the games is actually only its "50 Percent" Forme, and it possesses a much stronger Complete Forme resembling a [[http://cdn.bulbagarden.net/upload/1/14/718Zygarde-Complete_XY_anime.png bipedal mecha-esque kaiju]].
*** Barbaracle is a humanoid mass of barnacles, although it downplays the trope a bit by being only seven creatures.
** In ''VideoGame/PokemonSunAndMoon'':
*** The Water-type Wishiwashi is a small and individually weak fish that, through synchronized schooling with others of its kind, can become an enormous and powerful SeaMonster that is, on closer inspection, still composed of separate fish swimming together.
*** ''VideoGame/PokemonUltraSunAndUltraMoon'' introduces U.B Assembly, a [[StarfishAlien Ultra Beast]] that resembles a brick building. Each "brick" is a separate life form that comprises the whole creature.
*** Palossand's ''Ultra Sun'' Pokédex entry mentions that ''each of its grains of sand has free will''. As if that monstrous thing wasn't gruesome enough...
* Scarecrow (arm), Scarecrow (leg) and Mega Scarecrow from ''VideoGame/DevilMayCry 4'' are all basically burlap sacks filled with beetles with blades attached.
* The Dividers from the ''Franchise/DeadSpace'' series are actually a small colony of Necromorphs that bind together into a single, human-like entity. They fall apart once enough damage has been dealt to their combined form, requiring even more ammo to put the pieces down.
* The "Unknown" boss in ''VideoGame/{{Vanquish}}'' consists of a red core and pieces of robotic junk that assemble into various shapes.
* Throughout ''VideoGame/CastleRed'', there are numerous scenes in which the hero is attacked and knocked out by strange hooded figures. If you avoid the [[MultipleEndings first four endings]] and make it to the VeryDefinitelyFinalDungeon, these hooded figures will become standard enemies who reveal themselves as this trope when damaged.
* ''VideoGame/SuperMeatBoy'' has the boss of stage 4, Little Horn, made from a mountain of dead Meat Boys.
* In ''VideoGame/{{Dominions}}'', there is the spell ''Call the Worm that Walks". It is a powerful nature mage who escaped mortality by turning into this.
* Kelvin from ''VideoGame/{{Battleborn}}'' may appear to be a gigantic skeletal [[{{Snowlems}} ice golem]] but in reality he's an entire microorganism civilization with [[HiveMind a single consciousness]].
* ''VideoGame/DarkSouls'':
** Gravelord Nito from ''VideoGame/DarkSoulsI'' is this made out of ''human skeletons''.
** ''VideoGame/DarkSoulsII'' has a similar creature, The Rotten, except the bodies ''it's'' made of ''aren't skeletons yet''.
** The graveyard outside the Cathedral of the Deep in ''VideoGame/DarkSoulsIII'' is populated not only by ''[[ZergRush lots]]'' of undead, but also creatures made out of huge carnivorous maggots they can inflict you with. They come both in free-roaming forms and [[BodyHorror bursting out of undead enemies' bellies]] [[Film/TheThing1982 The Thing]]-style.
* According to the ''Hybrid Organ Research Report'' of ''VideoGame/SystemShock 2,'' Hybrids are partially comprised of a mass of worm-like symbiotes, that have taken over motor functions and decision-making functions. [[AndIMustScream This leaves the human brain largely intact and aware.]]

[[folder:Visual Novels]]
* [[spoiler:Zouken Matou]] from ''VisualNovel/FateStayNight'' will turn into The Worm That Walks whenever his current body is destroyed or worn out, after which [[BodyHorror he'll use the worms to attack someone and rebuild himself a new body from their flesh]].

[[folder:Web Comics]]
* "N" of ''Webcomic/CharbyTheVampirate'' turns himself into a swarm of cockroaches so often in his physiological torment of Blaine that Blaine recognizes a mass of the things in his room as the vampire even without seeing them while they are still in his shape.
* While it isn't entirely clear, one of the BigBad's lackeys in ''Webcomic/DeadOfSummer'' may be one of these. He summons a swarm of insects seemingly out of nowhere (the art suggests they either come from around him or ''inside'' him) to attack [[spoiler:[[Music/TheProtomen Commander]]]]. He's swarmed and bitten so much his movements are slowed, and he screams that they're eating him alive.
* In ''Webcomic/KillSixBillionDemons'', the GodEmperor Gog-Agog looks like a humanoid woman, albeit an UncannyValley-ish one. Then she takes a shot to the head, [[http://killsixbilliondemons.com/comic/ksbd-4-76/ revealing]] the mass of worms that ''really'' make up her body.
* Utchi-Skafatka in ''Webcomic/SchlockMercenary'' is a collective lifeform composed of countless flying insectoids. The protagonists first begin to realize that it is sapient when it [[http://www.schlockmercenary.com/2014-01-19 copies Sergeant Schlock.]]
* Gavotte, the head of the ''Webcomic/SkinHorse'' department, is a sentient swarm of bees. She (?) is surprisingly congenial and enjoys having a cup of tea with her employees, but they're often somewhat unnerved by the disembodied voice and the offers of free honey.
** The storyline "Grillo Parlante" introduces Daisychain, a string of mice which, as the name suggests, are linked in series, and the hedgies, hedgehog-like plant-creatures that can assemble into a giant hedgie as a defence mechanism.
* Laufian Slinten Pods in ''Webcomic/{{Spacetrawler}}'' are bunches of snakes who operate as a single entity by wearing an ill-fitting disguise of another alien species. It's implied the disguises are all of a specific member of said species, as seen when "Nogg, a Thelbiunn" meets "Nogathulbium".
* In a ''Webcomic/{{Weregeek}}'' [[http://www.weregeek.com/2009/06/15/ strip,]] during a ''D&D'' game, a helpful hermit reveals himself to be a "worm that walks". The player refers to the aformentioned ''Buffy'' episodes.

[[folder:Web Original]]
* In ''Podcast/WelcomeToNightVale'' episode 29, it's implied that the deer-masked subway representatives are this.
* ''Wiki/SCPFoundation''
** Discussed in [[http://www.scp-wiki.net/wjs-proposal WJS' SCP-001 proposal]], which details a conspiracy theory that certain people are actually worms that walk. People who are familiar with the conspiracy are susceptible to viewing others this way, so long as they [[spoiler:have memories of seeing a worm that walks]].
** [[http://scp-wiki.net/scp-906 SCP-906 ("Scouring Hive").]] SCP-906 are worms that can act as a colonial superorganism and gather together to form a humanoid body.
** [[http://scp-wiki.wikidot.com/scp-1249 SCP-1249 ("Pestilence")]]. SCP-1249 is a mass of land-based invertebrates that can form a humanoid body around a human skeleton. The invertebrates replace and function as human organs, muscles and skin.
* ''Literature/JohnDiesAtTheEnd'':
** A swarm of tiny insect-like aliens able to infest humans and walk around in their skin makes up the first abomination encountered, with the novel's characteristic sense of tact. "Just call me 'Shitload.' Because there’s a shitload of us in here." (A clever ShoutOut to [[Literature/TheBible Mark 5:9]], we might add.)
** Later, the narrator's Hyundai gets carjacked by a human-shaped pile of cockroaches.
* In ''Roleplay/RollToDodgeSavral'', [[OurLichesAreDifferent liches]] are undead made out of billions upon billions of spiders. A few temple guards also transform into spider-swarm organisms after being hit with a spell from one of the players.
* This is one theory behind what exactly [[spoiler: Ace]] of ''Roleplay/RubyQuest'' is.
* The Webcomic/BloodyUrban animated special ''Human'' has a swarm of newts masquerading as a human by wearing funny nose glasses and a trench coat.
* One article in ''Website/TheOnion'' is written by a pile of cockroaches pretending to be a human exterminator. The cockroachman attempts to convince people through the article it is writing to let cockroaches everywhere live and run free, but is unable to think of a compelling reason ''why''. It also laments that it knows that AfterTheEnd, cockroaches will rule the post-apocalyptic wasteland, but doesn't know ''when'' that will happen.
* ''WebOriginal/OrionsArm'' has the Mucoid Empire. Living in Cyberspace and alien species of worm that can form hiveminds and superorganisms.
* In a non-vermin example, [[WebVideo/AtopTheFourthWall Linkara]] once fought a monster that was made up of all 52 issues of ''ComicBook/CountdownToFinalCrisis''.
* Website/TGChan's Last Of the Messengers: the power of Reality Warping Speech allows people to transform themselves into millions of tiny bugs, among MANY other things. And yes, they do breed with themselves to create more "cells".
* It's technically "the swarm of frog fetuses that crawls", but ''WebOriginal/{{Mortasheen}}'''s [[http://www.bogleech.com/mortasheen/ovulooge.htm Ovulooge]] fits here like a glove. For a more traditional example (even though they don't quite look the part) are the Wormbrains. In their case, the creature itself is merely a (Usually [[WasOnceAMan formerly human]]) meat puppet for the billions of parasitic worms living inside of it.
* ''Podcast/TheMagnusArchives'' features both worm and spider versions of this in multiple episodes.

[[folder:Western Animation]]
* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', Jimmy meets some [[RidiculouslyCuteCritter ridiculously cute aliens]] who hate good music and love bad music. Whenever they hear good music, they morph into nasty little goblin creatures. If they hear ''more'' good music, they fuse together into one huge alien monster.
* On the ''WesternAnimation/AdventureTime'' episode "Little Brother," Kent fights the Rat King, who seems to be a giant rat head attached to a body made of rats. Oddly, Kent himself is ''literally'' a worm that walks, but doesn't fall under this trope (he just has legs and arms, for some reason).
* In ''WesternAnimation/AvatarTheLastAirbender'', the heroes meet a huge swamp monster that consists entirely of vines and a wooden mask. Unusually for this trope, however, [[spoiler:there's a guy inside, controlling the vines by bending the water in them. And that guy is a good guy; he's just using the disguise to scare away people whom he feels are a threat to the swamp. Later on, when the Day of the Black Sun comes to pass, he comes back to aid the resistance, wearing a similar costume made from seaweed and the same mask.]]
* In the first episode of ''WesternAnimation/Ben102016'', the villain uses a machine to attract and form a colossus entirely out of maggots to attack Las Vegas.
* ''WesternAnimation/CodenameKidsNextDoor'':
** The episode, "Operation: C.A.T.S." had a villainous CrazyCatLady who surrounded herself with her thousands of cats and basically made a cat-shaped HumongousMecha out of them.
** In the episode, "Operation: C.A.K.E.D.-T.H.R.E.E.", an army of chicks form a giant suit of knight's armor to help Numbuh One defeat the Delightful Children from Down the Lane's Giant Birthday Present Robot.
** The Delightful Reaper's face is made out of skulls that resemble the faces of those that it has assimilated.
* In one episode of ''WesternAnimation/TheDeep'', the Nekton family encounter a species of [[spoiler:octupus]] that cluster together and [[spoiler:use their camouflage ability to mimic larger creatures]].
* An episode of ''WesternAnimation/DrawnTogether'' had Vietnamese sweatshop workers assemble into a bipedal robot, anime-transform-sequence style to attack Spanky Ham.
* Similarly to the above example, in an episode of ''WesternAnimation/FamilyGuy'' an angry mob of wheelchair users joined together to form "Crippletron".
* One episode of ''WesternAnimation/SamuraiJack'' sees the titular Samurai [[spoiler: and Ashi]] face off against a creature known only as Lazarus 92, a mass of slimy blue leeches that attack like a single organism.
* In an episode of ''WesternAnimation/GoofTroop'', Pete gets turned into a fly and is forced to train with other flies. Pete's family gets him back to change him back, but before they do, the whole swarm of flies comes to the door wearing a trench coat to attempt to steal Pete back.
* In ''WesternAnimation/InvaderZim'' [[WaveOfBabies a bunch of baby-like aliens]] combine into a giant bipedal monster.
* In ''WesternAnimation/MaxSteel'', the villain Bio Constrictor was made of dozens of snakes.
* One episode of ''WesternAnimation/MuchaLucha'' was about Ricochet, Buena Girl, and the Flea confronting a giant spider-themed wrestler named Black Widower, who has been beating several insect-themed wrestlers all over town, and is threatening to do the same to the Flea. At the end of the episode, the Black Widower is defeated, and as a result, his costume comes off to reveal the aforementioned insect wrestlers.
* ''WesternAnimation/ThePowerpuffGirls'':
** The girls once fought a bug-themed villain called the Roach Coach, who gathered all Townsville's cockroaches into a single giant warbug. The Roach Coach himself while not exactly a Worm That Walks, is nevertheless a bug in a MobileSuitHuman.
** In the Nanobots episode, the bots coalesce into a Monobot.
* In ''WesternAnimation/ReBoot'', we have Nulzilla. We also have [[spoiler: Enzo and Dot's father]], who can regain a bipedal form and his ability to speak by making a sprite-sized body of nulls, with the null that used to be him as the head. Both creatures were made possible through the powers of Hexadecimal.
* ''WesternAnimation/StaticShock'' has had a couple:
** One episode featured a giant carnivorous BlobMonster composed of billions of microscopic organisms that had been affected by the gas that created the "Bang Babies". Static and Gear remark that, while the creatures normally should just "blob around doing nothing", the affected ones "move like Soul Train dancers".
** A minor foe was either a giant insect who could dissolve into a swarm of tiny copies of himself or a swarm of insects fond of forming into a giant copy of themselves. That is actually an enemy of the African hero, Anansi, employed by his arch-enemy Osebo.
* There's an episode of ''WesternAnimation/TimonAndPumbaa'' where Timon pays this guy to help Pumbaa. After everything he tried didn't work, he came back to the guy to get his money back, but the guy turned out to be a swarm of locusts.
* ''WesternAnimation/ScoobyDooMysteryInc'': The Cicada Creature from "When the Cicada Calls".
* In ''WesternAnimation/SpiderManAndHisAmazingFriends'', the [[http://www.youtube.com/watch?v=ygTy4QhTm3g Swarm]] was an absolutely terrifying entity that consisted of a hive of bees that combined to create a sentient being.
* On the ''WesternAnimation/{{Futurama}}'' episode "Benderama", Bender assembles microscopic clones of himself into one giant Bender to fight an alien giant.
* ''WesternAnimation/GravityFalls'':
** In "Tourist Trapped", the gnomes first try a TotemPoleTrench, then gather together into a giant gnome in order to get Mabel to become their wife.
** The Summerween Trickster from "Summerween" is actually composed of "loser candy", all the Halloween candy that no one wants and throws away.
** The denizens of Mabeland in "Weirdmageddon Part II" are this, as Mabeland Wendy dissolves into maggots when Dipper rejects her advances (a ploy to get him to stay in Mabeland forever).
* The true form of ''Franchise/MastersOfTheUniverse'' villain King Hiss is that of 5 or 6 large snakes in a human shell. All of his toys have a "pop open his torso and see the snakes" gimmick.
* In the animated ''WesternAnimation/TheTick'' series, the hero first encounters a colony of angry ants when they steal stuff when using composite human form.
* A variation (similar to the ''Gravity Falls'' gnome example above) occurs in the ''WesternAnimation/PhineasAndFerb'' episode "Unfair Science Fair Redux". The small Martians join into a big version of themselves when Candace decides she doesn't want to be queen of Mars anymore and flees.
* Another variation on this comes in the first season finale of ''WesternAnimation/ActionMan2000''. A rogue mass of Trilobugs assembles itself into the form of Alex's friend and rival Brandon, which stands about 100 feet tall. Brandon's consciousness, which had been removed from his body when [[EvilutionaryBiologist Dr. X]] [[GrandTheftMe took it over]], had implanted itself into one of the Trilobugs and had been taking control of the others.
* ''WesternAnimation/RickAndMorty'' gives us a rare heroic version in the superhero One Million Ants, who is... [[ExactlyWhatItSaysOnTheTin one million ants]] in a humanoid shape.

[[folder:Real Life]]
* While they can't construct a bipedal form and go for a walk, South American army ants regularly form nests and bridges from their own massed bodies.
* Blister Beetle Grubs form themselves into the shape of the female of a certain species of bee, in order to lure it into trying to mate with the bee-of-worms, which secretes pheromones to help the process along ("Hey, that doesn't look like a bee and *sniff sniff* Oh Baby..."). Then they cling to the male, transfer to the female when Real Bee-boinking goes on, all to hitch a ride to the female's nest, which is full of tender bee larvae.
* [[http://en.wikipedia.org/wiki/Portuguese_Man_o%27_War The Portuguese Man o' War]] looks like a floating jellyfish, but is in fact a colony of four organisms known as polyps. Its tentacles can grow to twenty metres in length (ten is average) with a sting that can be very painful. Definitely not something you want to get tangled up with, especially since Portuguese Men o' War are most commonly found in large groups.
** The Portuguese Man o' War is one of a number of creatures in the order [[https://en.wikipedia.org/wiki/Siphonophorae Siphonophorae]], of which there are three suborders. Counted among them is the gigantic ''[[https://en.wikipedia.org/wiki/Praya_dubia Praya dubia]]'', which can grow to lengths of 130ft, making them the second-largest marine organism on the planet.
* Slime molds, are essentially single-celled organisms that every now and again come together to form composite creatures, up to roughly 30cm x 20cm in extreme cases.
* [[PantomimeAnimal Animal costumes]] that require multiple people, the most famous examples being 2-person horse costumes and Chinese New Year dragons.
* Evolutionary biologists believe that multicellular organisms are descended from single-celled organisms that formed 3-D colonies.
** Likewise, eukaryotic cells probably arose when some oxygen-utilizing eubacteria set up housekeeping inside of anaerobic archaean bacteria, creating composite protists and fungi. When cyanobacteria joined the party, we got algae and (eventually) plants.
** More in the now, multicellular life (yes, including [[HumansAreCthulhu you]].) tends to host multitudes of bacteria and other single cell-organisms to mutual benefit.
* Tubifex worms, in the absence of soil, will cling to each other. And to walls, which gives an effect not dissimilar to both this and MeatMoss.
* [[http://www.youtube.com/watch?v=WgSj9VuDcVU Sawfly larvae]] climb over each other in order to move faster as a group.
* Tropical trees don't walk, but they harbor enough symbiotic fungi, encrusting mosses or lichens, clinging vines and epiphytes, and boring invertebrates to constitute colonial super-organisms.
