->''"Ford, you're turning into a penguin. Stop it."''
-->-- '''Arthur Dent''', ''Literature/TheHitchhikersGuideToTheGalaxy1''

A character is transformed into an animal, either completely or {{partial| transformation}}ly (as in TwoBeingsOneBody). The defining quality for this trope is whether their transformation was {{voluntary| shapeshifting}} or [[InvoluntaryShapeshifting not]]:

* There are many characters whose ability to transform into animals is a special power. Several of these are [[VoluntaryShapeshifting Shapeshifters]] whose power is limited to animal forms, and oftentimes a set number at that. There are also quite a lot of ShapeShifting characters who can turn into anything, but prefer to transform into animals, presumably because you can get more done in the shape of a living being than something inanimate. OurWerebeastsAreDifferent covers werebeasts.

* Others are characters [[InvoluntaryTransformation unwillingly transformed]] into animals, usually as a punishment ([[KarmicTransformation ironic]] or otherwise) or {{curse}}, more often than not by the [[BlackMagic dark magic]] of the BigBad. In any case, regardless of species, the target is none too happy about being an animal. (Indeed, for some reason, characters are often just as upset over being turned into swans as they would be if they were turned into worms. There is an intriguing amount of CursedWithAwesome associated with this trope.) The target may lose the ability to speak, and must work hard to get the message to their friends about what happened. This is sometimes combined with a FreakyFridayFlip, leaving the animal's mind trapped in the human character's body (where HilarityEnsues). This is frequently accompanied with some sort of time limit, after which it will be difficult or impossible to reverse the process.

In any case, a physical transformation into an animal may be accompanied by a [[TheMindIsAPlaythingOfTheBody mental transformation into that animal]], more so if it was involuntary. It may also allow the character to use whatever skills and abilities (like a keen nose or ability to fly) are associated with that animal ... as well as whatever strange instincts or unhygienic behaviors may also be associated with that animal.

The transformation itself may be scientific in origin, or mystical. Popular mystical transformations include werewolves and other {{werebeasts}}, [[TotallyNotAWerewolf wolves]] (who may be confused for werewolves), or such chestnuts as a witch [[BewitchedAmphibians turning people into toads]]. And who can forget such classic fairy tales such as [[Theatre/SwanLake swan maidens]] or Literature/TheFrogPrince? In fact, Animorphism is OlderThanFeudalism, with ''Literature/TheOdyssey'' describing Circe turning Odysseus' sailors into pigs.

See also BalefulPolymorph, from which this is the consequence, and {{Transflormation}}, another morphological shift. Contrast with HumanityEnsues, the rarer converse in which animals transform into humans.

Not to be confused with the SlidingScaleOfAnthropomorphism. See also PettingZooPeople. If this character is a superhero or supervillain, then they are an AnimalThemedSuperbeing.

Not to be confused with [[http://en.wikipedia.org/wiki/Anamorphism anamorphism]], [[http://en.wikipedia.org/wiki/Anamorphic_lens either kind]].

!!Examples of Voluntary Animorphism


[[folder:Anime & Manga]]
* All familiars, and [[WeaselMascot Yuuno]], in ''Franchise/LyricalNanoha''.
* Ichigo of ''Manga/TokyoMewMew'' is a borderline case. The intended effect of her cat genes is the ability to voluntarily transform into a CatGirl; however, as her cat DNA starts to overtake her human DNA, she starts involuntarily growing cat ears and tail when excited, and eventually begins to fully transform into a cat. Another recurring character in the show can become a cat voluntarily, but only for a limited time.
* Yoruichi in ''Manga/{{Bleach}}'' spends a lot of the series as a cat because she likes to. Most of her transformations to and from human are to mess with other members of the cast (like Ichigo).
* ''Manga/OnePiece'' has the Zoan variety of [[PowerUpFood Devil Fruits]], which allow the eaters to transform into a certain animal depending on what the fruit is, as well as a half-human hybrid of said animal (and yes, even humans are counted as an "animal"). Most fruits have a certain "model" for animals that are in the same family (EX: Dog Dog fruit, Model Wolf), or different sub-branches like "Awakened" which is more beast then man, "Mythical" like a Phoenix, and "Ancient" like a T-Rex.
** Even inanimate objects can "eat" a Zoan Devil Fruit: they gain characteristics of a living being and their corresponding animal's intelligence, and can also transform into the animal itself, a hybrid (in the absence of a better word) or their "original" object form.
** If an animal eats a Zoan fruit corresponding to its own species, it apparently "enlightens" them. [[spoiler:This case appears in Fleet Admiral Sengoku, who ate a Mythical Zoan, Human Human Fruit, Model: Great Buddha.]]
* Early in the series, Kotaro of ''Manga/MahouSenseiNegima'' with his powers sealed revealed the ability to become a small puppy. [[spoiler:Later events show that he can, at full power, become a [[SuperMode Super-Powered wolf]]]].
* ''Manga/AiToYuukiNoPigGirlTondeBuurin'' is about a [[MagicalGirlWarrior warrior]] style MagicalGirl (think ''Franchise/SailorMoon'', ''Anime/TokyoMewMew'', or ''Anime/PrettyCure'') whose magical form is... a super powered pig. She does this willingly, but grudgingly, in order to earn pearls for good deeds so that once she gets OneHundredAndEight of them she can become a human superheroine instead.
* Essentially the entire point of ''Manga/PlusAnima''.
* In ''Manga/RuinExplorers'', Ihrie was cursed as a child so that she turns into a mouse whenever she casts magic. Fortunately, she carries along a medicine that can reverse the effects, though having a limited supply at any one time means she still has to choose her battles.
* Anime/{{Pokemon}} has an episode in the Johto League saga wherein [[TheHero Ash]] meets a witch named Lily. She has a recipe for a potion that will let you read a Pokemon's mind, but needs some ingredients first. At the end of the ep, [[spoiler:Ash is turned into a Pikachu, which is affectionately [[FanNickname nicknamed Ashachu]]]]. It launched a hundred FanFic sequels when that happened.
* Rumiya and Ryo-Ohki in ''Anime/PrettySammy''.
* Some fairies in ''Manga/FairyNavigatorRuna'' have animal forms as well as human ones.
* Kars from ''Manga/JojosBizarreAdventure'' can do this after becoming the UltimateLifeform. He can do this because his cells contain the DNA of every species of animal, insect and even plant, on Earth and can manipulate said cells to transform his whole body or just parts of it into entire animals or just a single part of said animal.
* In ''Manga/MarvelousMelmo'', the titular character can do this via her candies: their main use is [[FountainOfYouth to change a]] [[OvernightAgeUp person's age]], but Melmo can also cleverly use them to regress herself into a fetus, then age herself back into whatever animal she wants to become.
* The entire premise of ''Manga/KillingBites'' revolves around this.

[[folder:Comic Books]]
* Snowbird from ''ComicBook/AlphaFlight'' is an Inuit demi-goddess who can shift into any animal, but it's always an albino female. For a time, she could only shift into creatures native to Canada (for that matter, she couldn't leave the country's borders without dying). Those restrictions faded with her immortality [[GrowingUpSucks when she lost her virginity]], but she still uses Arctic creatures as a preferred style.
* Changeling--formerly Beast Boy--from ''Comicbook/TeenTitans''. Like his cartoon counterpart, he can turn into a green version of any animal (though he can't turn into larger animals without [[ShapeshifterBaggage strain]]). But unlike the show, he can speak in any form. This is because he's not ''limited'' to turning into animals, it's just his style.
* Viktor Romanov in ''Comicbook/NikolaiDante'' can turn into a giant eagle due to his weapon crest.

[[folder:Fan Works]]
* In ''[[https://www.fanfiction.net/s/11989539/1/Hakkōna Hakkōna]]'', Obake are creatures that can shapeshift into just about anything, including animals. Unfortunately, their powers made them [[CursedWithAwesome feared by humans]] and [[GottaKillThemAll massacred as a result]] with [[spoiler:Kiku as the only survivor.]]
-->Obake. A subcategory of Yōkai, supernatural creatures of Japanese Shinto myth. Obake are beings that can take on any shape, from an inanimate household object to the most ravenous of beasts. However, despite that, Obake can be of various species, possessing various base forms; cat, dog, monkey, even human are just some of them. Obake have generally lived in peace, respecting all those around them. Secluding themselves from people, they are one with nature, in perfect harmony with it and each other as they live through existences which aren't limited by the passing of time. Everything was perfect until that fateful day...
* In ''FanFic/TheSecretLifeOfTheBackyardKids'', Tiffany transforms into a giant cat, and since Jorge is a SquishyWizard, he calls his nanny and she tells him to transform into a panther. He not only does just that but does a ShoutOut to Music/MichaelJackson.
* In ''FanFic/FriendshipIsOptimal'', humans are transformed into a pony upon [[BrainUploading uploading]] to Equestria.
* In ''FanFic/DiariesOfAMadman'', Nav gets turned into a pegasus several times by the shapeshifting spell, but he hates every second of it.
* TD experiences being turned into a pony several times in the various ''FanFic/TheNonBronyverse'' stories (not all of which are canon). The AU story ''TD the Alicorn Princess'' is the biggest example, when he ends up trapped in the form of a female alicorn.
* Inverted with Celestia and Chrysalis in ''Fanfic/MyLittlePiratesLuffysAdventuresInEquestria'', who are ponies (or a look alike in Chrysalis' case) that can turn into humans. Their fighting style is similar to all Zoan Devil Fruit users as they can use magic to summon their wings to fly or turn back their limbs to their original equine shape for devastating hits.
* In ''Fanfic/YourHumanAndYou'', Max gets turned into a pony after accidentally consuming a transformation potion.
* In ''Fanfic/ReturnOfThePrimarchs'', Shrike, who spent decades fighting Orks, manages to hijack their gestalt psychic field and use it to transform into enormous raven, turning it against them.
* ''Fanfic/LegacyOfKainDivusSaga'': Kain repeatedly makes use of his Wolf and Bat forms.
* ''FanFic/TheFableOfJoyfulWing'': The Wolf King and the Wolf Queen are spirits who can change between the forms of humans and enormous wolves at will, and their students can take the forms of foxes.

* One third of the premise of the series ''Literature/{{Animorphs}}''. (The other 2/3 are AlienInvasion and RagtagBunchOfMisfits.) Also the TropeNamer. Limitations include having to touch an animal to "acquire" its DNA before being able to transform into it, and being limited to precisely two hours in animal form before suffering ShapeshifterModeLock.
* The sorcerers in ''Literature/TheBelgariad'' can turn into pretty much anything they like, though Belgareth is fond of wolves, who are apparently semi-magical themselves in the setting: Belgareth's wife ''was'' a wolf, who figured out how to transform by watching Belgareth do it. Most of the other sorcerers prefer some type of bird.
* Daine in Creator/TamoraPierce's ''Literature/TheImmortals'' quartet is a shapeshifter thanks to her WildMagic. She has increasing control over her transformations as the books go on, though she retains her human mind even within the animal shape. The problem of her keeping her human and animal self separate is briefly addressed in ''Wild Magic'', but [[AWizardDidIt takes little time to fix once she tells Numair, the most powerful mage in the world, that she's having trouble.]]
* Several characters in the ''Literature/HarryPotter'' series (such as Professor [=McGonagall=] and Sirius Black) are "animagi", who can transform into specific animals ([=McGonagall=] becomes a cat, [[MeaningfulName Black]] a large dog). Unlike most instances, this practice is very strictly watched by the government (who keeps tallies on the number), and is said to be incredibly hard to do. Unfortunately, the animal one changes into is not chosen by the wizard, but instead determined by their character traits. For example, the cowardly and sneaky [[spoiler:Peter Pettigrew]] turns into a rat.
** Hermione Granger turns into a CatGirl after mixing the wrong hairs in [[CoverIdentityAnomaly a Polyjuice Potion]]. Hilarity Ensues, to Moaning Myrtle.
* In ''Literature/PresidentsVampire'', vampires who drink human blood gain variety of supernatural skills, one of which is ability to turn into birds. It's implied that they can change into other animals as well, but this remains to be seen, as the main character drinks animal blood only. In any case, MagicPants are not in effect.
* Wizards in Creator/UrsulaKLeGuin's ''Literature/{{Earthsea}}'' books are capable of transforming into animals, though the process is dangerous. In one particularly memorable example, the protagonist Ged turns into a hawk in order to escape an enemy -- and, forced to spend weeks in his new form, almost ends up getting [[ShapeshifterModeLock stuck that way]].
* ''Literature/DoraWilkSeries'' has a fair share of animal shapeshifters, werebeasts and others. Usually, they change fully, but some can train themselves to retain human body, but thing such as animal hand or legs.
** Werewolves, obviously. Their goddess Faoilinara can turn into a wolf as well.
** Szelma can turn into a cat, although it seems there's no werecat species.
** There are people who can turn into lions and tigers, although only one (a were-tiger) appears in the books.
** Gods Badb and Loki can turn into any animal they wish, although the former prefers a giant crow.
* Wizards in ''Literature/{{Nightrunner}}'' can turn themselves and others into an animal form that is said to be their "true nature." The fact that it can be done to others, of course, means it's not ''always'' voluntary.
* Many of the evil characters in The ''Literature/{{Caretaker}}'' Trilogy are {{Half Human Hybrid}}s of some sort, but the only one shown to actually be capable of turning into the animal whose traits he borrows is Colonel [[MeaningfulName Aranha]]. [[spoiler:For those who didn't get the [[MeaningfulName Meaningful Portuguese Name]], he turns into a gigantic tarantula.]]
* In ''Literature/TheThiefOfAlways'', victims of the BigBad turn into [[spoiler:creepy, giant fish when their souls are removed]]. [[BodyHorror It's a gradual process]].
* The Were Hunters in Sherrilyn Kenyon's ''Literature/TheDarkHunters'' series were created by a king using his children, animals, and MagicGenetics to create {{Shapeshifting}} progeny.
* In the ''Literature/{{Xanth}}'' series, Dolph can turn into any living thing as his magical talent, while his grandfather Trent can turn any living thing into another living thing as his.
* Dinah and Dorinda, the main characters of Eric Linklater's children's novels ''Literature/TheWindOnTheMoon'', use a magic potion given to Dinah by a witch in order to transform themselves into kangaroos. They are, however, stuck in kangaroo form until they can locate the bottle with the potion to transform them back to humans, which leads to them being caught and put in a zoo. In the zoo, they also meet Mr. Parker, formerly a human detective, who was transformed into a giraffe for no apparent reason (he blames it on wishing he was taller back when he was human).
* In the ''Chronicles of the Cheysuli'' series, the eponymous Cheysuli can turn into the shape of their Lir (a BondCreature that is some kind of animal bear, wolf, hawk...); some can turn into the form of any Lir they want.
* In Rick Riordan's ''Literature/TheHeroesOfOlympus'' series, Frank Zhang, a demigod son of Mars, can be anything. According to Mars this means anything within reason, any living animal. [[spoiler:This gift did not come from Mars however, but Poseidon, who is a distant ancestor on Frank's mother's side. His whole family can do it, and have for generations going back to Periclymenus a legendary Greek hero on whom Poseidon first bestows this gift. Percy, Poseidon's actual son, is noticeably jealous of Frank's gift.]]
* Everyone in ''Literature/TheLastDove'' can (somewhat) voluntarily shapeshift.
* In the ''Literature/NightshadeTrilogy'', the Guardians can turn into wolves at will.
* Hoole in ''Literature/GalaxyOfFear'' is of a shapeshifting species but, while Shi'ido are able to turn into anything at will, he only ever takes the shapes of different sentient species -- Wookiees are a favorite -- or animals, rather than ever staying with his default form and lengthening his arms, say. Though he ''is'' able to speak Basic while Wookiee-shaped, which real Wookiees can't do.
* ''Literature/TheDresdenFiles'': One of the many things [[FunctionalMagic magic]] can do. Mainly used by Billy's {{Werewolf}} gang, for combat applications.
* Simon is turned into a rat in ''Literature/{{City of Bones|2007}}''.
* [[Literature/{{Reckless}} The Mirrorworld Series]]: Fox, who prefers her animal form [[spoiler:until she [[GreenEyedEpiphany sees Jacob kissing Clara]]]].
* ''Literature/AFantasyAttraction'' has Mr. Smith accidentally transforming people into [[spoiler:baby animals with his [[MagicWand spork]]]].
* ''Literature/SpectralShadows'' has this when Christine gets turned into an anthro fox via Sir Jon's SoundChaser.
* Inverted in the fifth book in the ''Literature/{{Spellsinger}}'' series. A freak perturbation of reality (they've been happening a lot lately) turns the entire party of anthropomorphic animals into humans. Jon-Tom comes up with a spellsong that turns humans back into animals to save them ... [[spoiler:not realizing it would also affect ''him,'' playing the trope straight.]]
* In ''Literature/TalesOfElethiya'', one of the predominant supernatural races, the Serahn, are each given a power animal at birth. When they become of age, and if they have the gift, they will have the ability to morph into that animal to protect and serve the good of humankind.
* In ''Literature/ASchoolForSorcery'', voluntary shapechanging into an animal is a possible gift. Lina Mueller, roommate of the protagonist, can transform into a panther.
* Discussed in Creator/RyuunosukeAkiyama's ''A Terribly Dangerous Coat'', Ishiria and Luran discuss the fact that Luran wanted to be a bird when he grew up; Ishiria points out several reasons Luran might not like being so transformed, but he does not listen to her, though it seems impossible with in-setting magic anyway.
* ''Literature/ReleaseThatWitch'': The witch Maggie has the magic to turn into an oversized version of any bird she's ever seen. This eventually extends to include bird ''monsters'' as well.

[[folder:Live-Action TV]]
* ''Series/{{Manimal}}'' has a main character with transformation into animals as a special ability.
* From ''Series/BlackadderTheThird'':
-->'''Blackadder''': Baldrick, who gave you permission to turn into an Alsatian?
* In ''Series/TrueBlood'' there is a shapeshifter community. They can turn into any animal they want; they just have to see it in order to "copy" it. There is however an exception: each person has an animal that they feel comfortable with, and can transform into it at any time without having to see a real example. The ability is passed from generation to generation.
* The TV miniseries ''Series/{{Earthsea}}'' had a story about a wizard who got so obsessed with shapeshifting into a bear that the bear's personality eventually displaced his own, causing him to eat his entire family. The story comes from the first Earthsea novel, ''Literature/AWizardOfEarthsea'', where the bear-wizard is only said to have killed his son.
* ''Series/MythQuest'' has the protagonists going into multiple myths. Naturally, this happens.
** Loki turns himself into a bird in "Hammer of the Gods".
** In "Red Wolf's Daughter", the spirits of Eagle, Badger, and White Buffalo are summoned. All take human form.

* Done in the "Metamorphosis" illusion from ''Pinball/TheatreOfMagic'', where the magician turns into various animals, such as a dove, a tiger, or a cobra.

[[folder:Tabletop Games]]
* The ''TabletopGame/NewWorldOfDarkness'' sourcebook ''Skinchangers'' has options for playable characters using almost every possible variation of this trope, with ''War Against The Pure'' and ''Changing Breeds'' adding a few more for good measure.
** Almost every type of supernatural creature in the TabletopGame/NewWorldOfDarkness is capable of shapeshifting into an animal by one means or another.
*** [[TabletopGame/ChangelingTheLost Changelings]] have the Contracts of Fang and Talon
*** [[TabletopGame/GeistTheSineaters Sin-Eaters]] have the Primeval Caul
*** [[TabletopGame/MageTheAwakening Mages]] have Life magic.
*** [[TabletopGame/PrometheanTheCreated Prometheans]] have the Metamorphism Transmutation
*** [[TabletopGame/VampireTheRequiem Vampires]] have the Protean Discipline
*** [[TabletopGame/WerewolfTheForsaken Werewolves]] are all inherently shapeshifters without having to learn a specific power.
* The ''TabletopGame/OldWorldOfDarkness'' games featured shapeshifting {{Splat}}s as well.
** ''TabletopGame/WerewolfTheApocalypse'' is obviously about werewolves, but also lets you play as were- hyenas, spiders, cats (lions, tigers, leopards, lynxes, etc.), ravens, bears, foxes, crocodiles/alligators/lizards, snakes, coyotes, rats, and sharks. Extinct races include the werebats, wereaurochs, and wereboars (though even they have rules for playing them).
** ''TabletopGame/VampireTheMasquerade'' has three clans with specialized disciplines that allow for animal shapeshifting: the Gangrel have Protean (the typical bats, wolves, and fog, though variations exist); the Followers of Set have Serpentis (guess); and the African bloodline Akunanse have Obomwe, which allows the Kindred to turn into ''any'' animal provided she smears her body with its blood (the creature must obviously be big enough to have enough blood for this to be possible).
** ''TabletopGame/ChangelingTheDreaming'' has the pooka, selkies, commoner hsien, and inuas (a Native American kith). A member of these kiths has one animal form that she can shift into. The pooka and inuas choose one at character creation, while the selkies turn into seals, and each commoner hsien kith has one animal form its members shift into: cats, fish, monkeys, snakes, and badgers (in case you're curious, the noble hsien kiths are based on the 5 Taoist elements)
* In ''TabletopGame/{{Exalted}}'', the Lunar Exalted are able to take the form of any species, so long as they've drunk the heart's blood of a member of that species, and can build up an impressive library of forms this way. They can also apply this to humans, although it works a little differently (each human form they add to their library allows them to take that /specific/ human form).
** It actually works that way for animals too. You are taking ''that'' animal's form. It's just that the most common hunt is for one that's an excellent specimen but doesn't stand out. You could, say, hunt an espionage target's favorite dog so you'd be close to him for an extended period.
* The ''TabletopGame/DungeonsAndDragons'' Barbarian-based [[PrestigeClass PrC]] ''Bear Warrior'' is able to transform into a type of bear while they rage.
** And druids can turn into any animal.
** Wizards too, with the right kind of spells. And (like druids) transform others into harmless critters as per the second example of this trope.
* In ''TabletopGame/NewHorizon'', Medeans merge with the genetic code of the native wildlife. Unlike most other examples of this trope, this is PERMANENT... although, oddly, it doesn't effect any kids they have.
* ''TabletopGame/BleakWorld'' has the vampires and princesses. Their forms are different based on what kind of vampire or princess, with Dracul vampires being able to turn into bats and wolves, whereas primal vampires can turn into a dragon.

* The classic Creator/EugeneIonesco play ''Theatre/{{Rhinoceros}}'' has an entire town choosing to become rhinoceroses.

* Tha Makuta in ''Toys/{{Bionicle}}'' liked to take on animal forms, most famously Miserix, who preferred reptile forms to his original body (his only existing official image also has him turned into a dragon). The Phantoka Makuta team chose the form of bats, while the Mistika team took on the semblance of insects. However as a subversion, due to a mutagen, they couldn't turn back.

[[folder:Video Games]]
* Druids in ''VideoGame/WarcraftIII'' could turn into the totem animal whose demigod they were devoted to.
** Druids in ''VideoGame/WorldOfWarcraft'' can turn into various animal shapes. Bear, Cat, Seal (or Orca), Stag (or Cheetah), Bird, [[{{Transflormation}} Tree]], bigger Tree, and an owlbear thing.
** Dragons are also known to have a human form, notable ones being Kalecgos, Alexstraza, and Neltharion (Deathwing as most players know him).
** It's not ALWAYS human. Alextraza and her consert turn into High Elves, Chronomaru turns into a Gnome, Ysera becomes a Night Elf. Goblin and Blood Elf forms have been seen as well for other dragons. Also Deathwing human forms or his human one has changed a lot since his days as Lord Prestor.
*** Deathwing's human Form retains the reforged lower jaw that he has in his dragon form. (See FridgeHorror.)
* Druids in ''VideoGame/DiabloII: Lord of Destruction'' can acquire the ability to turn into a werewolf, or the slightly-more-exotic werebear.
* ''Videogame/FireEmblem:''
** Most Manaketes/Dragons can transform from one form to the other, with varying degrees of ease. In most games, the transformation requires the use of a Dragonstone that has a limited number of uses. However, there are a few unique cases because the games all take place in different universes.
** In ''VideoGame/FireEmblemShadowDragonAndTheBladeOfLight'' and ''Videogame/FireEmblemMysteryOfTheEmblem'' (and their remakes), Manaketes could generally transform into different types of Dragons depending on which kind of Dragonstone they used.
** ''Videogame/FireEmblemPathOfRadiance'' and ''Videogame/FireEmblemRadiantDawn'' added the Laguz, of which Dragons were one of the many races, who could transform into beast forms and back at will, though they would revert to their humanoid state when they ran out of transformation points. A select few characters (the [[AsskickingEqualsAuthority rulers of the respective laguz tribes]]) could stay transformed as long as they willed it, while ''Radiant Dawn'' introduced the "halfshifting" skill, which allows a laguz to stay transformed indefinitely, [[WillfullyWeak but with their stats cut to make up for it]]. In ''Path of Radiance'', the Laguz would transform without the player's choice or input when their meters were full, but ''Radiant Dawn'' allowed the player to activate it whenever they wanted so long as they had transformation points to use.
** ''VideoGame/FireEmblemAwakening'' uses a simplified Dragonstone system for Manaketes, and combined Manakete and Laguz mechanics for the Taguel, who use Beaststones to turn into giant rabbits.
** ''VideoGame/FireEmblemFates'' has the [[MedievalEuropeanFantasy Nohr]]-exclusive Wolfskin and [[{{Wutai}} Hoshido]]-exclusive {{Kitsune}}, who both use Beaststones to respectively transform into ogre-like werewolves and giant foxes. The player avatar him/herself [[spoiler:and their children]] can transform into a dragon with the use of a Dragonstone. Unlike most other ''Fire Emblem'' games, the transformation stones has infinite uses.
** [[Videogame/FireEmblemTheBlazingBlade The seventh game]] (released in the West as simply ''Fire Emblem'') seems to imply that (at least for the ''Elibe''-verse) it's quite difficult for dragons to switch from form to form without losing their memories and personalities from their other forms.
* In the ''VideoGame/BanjoKazooie'' series, visiting one of two shaman-type characters (Mumbo-Jumbo in the original and ''Grunty's Revenge'' or Humba-Wumba in ''Tooie'') would allow you transform into different things; this is usually an animal (but not always; other transformations have included a tank, a submarine, and a washing machine). Oddly, the main characters are ''already'' animals.
* The entire premise of the ''VideoGame/BloodyRoar'' game series is based on this trope.
* Likewise ''VideoGame/EVOSearchForEden''.
* ''VideoGame/AlteredBeast'' has the {{werewolf}}, [[InstantAwesomeJustAddDragons dragon]], {{bear|sAreBadNews}} and [[MisplacedWildlife tiger]] forms. Also for the BigBad, he has a [[MisplacedWildlife rhinoceros form]].
* ''Franchise/TheLegendOfZelda'':
** In ''VideoGame/TheLegendOfZeldaALinkToThePast'', entering the Dark World without the protection of the Moon Pearl causes Link to transform into an adorable, defenseless, pink bunny-man.
** In ''VideoGame/TheLegendOfZeldaTwilightPrincess'', Link transforms into a wolf. It is initially involuntary due to the Twilight invading Hyrule, then Zant curses Link to make it permanent; eventually, the Master Sword breaks the curse, and Link gains the ability to transform at will. Interestingly, instead of throwing away the gem that cursed Link in the first place, they hold onto it, and apply and remove it using the Master Sword to switch forms.
* In ''VideoGame/{{Okami}}'', the Oina tribe of [[SlippySlideyIceWorld Kamui]] are able to transform into wolf or dog forms and back.
* ''VideoGame/{{Solatorobo}}'' provides a rare inversion: In a world populated by anthropomorphic dogs and cats, the main character can transform into a human to become more powerful.
* In ''VideoGame/KingdomHeartsII'', one of the visitable worlds is the [[{{Disney/TheLionKing}} Pride Lands]]. While there, [[{{TheHero}} Sora]] is transformed into a [[KillerRabbit brown lion cub]] thanks to his clothes. Goofy and Donald are also transformed into, respectively, a tortoise and a bird... that can actually fly.
* On gaining the Transformation Staff, characters in ''VideoGame/FinalFantasyThe4HeroesOfLight'' can turn to and from animals at will (which becomes helpful and sometimes necessary because of AnimalTalk). Aire is a cat, Yunita a rabbit, Brandt a dog, and Jusqua... a chicken.
* One of the main features of ''{{VideoGame/Splatoon}}'' is the ability to turn into a squid and dive into ink of your team's colour, refilling your own ink in the process. You also move faster this way. (Of course, the Inklings may actually be anthropomorphic squids.)
* From the ''{{VideoGame/Bayonetta}}'' franchise, the titular character can use several "Beast Within" spells to transform into different animals, including [[PantheraAwesome Panther Within]], [[CleverCrows Crow Within]], and [[BatOutOfHell Bat Within]]. In ''{{VideoGame/Bayonetta 2}}'', Bayonetta gains a new Beast Within transformation, [[ScaledUp Snake Within]]. [[SecretCharacter Unlockable characters]] get their own variants as well (although they are functionally the same), with Jeanne able to transform into a Lynx, Owl, Moths, and a giant Centipede, Rosa able to turn herself into a Tiger, Falcon, Hornets, and a Cobra, and even Lumen Sage, Balder, is able to turn himself into a White Wolf and an Eagle. Non-playable character, Loki, also has the ability of transforming himself into a Flying Squirrel.
* This is a part of the gameplay in the NSFW game ''Corruption of Champions''; various plants and items are founds across the land that changes the PlayerCharacter. For example, eating enough Canine peppers[[labelnote:What is it?]]A pepper that resembles an erect dog penis. Brings a new meaning to "eat a dick", don't it?[[/labelnote]] changes you into a [[LittleBitBeastly dog boy/girl]], eating more turns you into a [[PettingZooPeople Dog-morph]], and eating too many will transform you into a regular dog which [[MultipleEndings makes you forget that you were ever human in the first place.]] This applies to all animal-morph items.
* In ''VideoGame/Persona5'', your party will occasionally be turned into mice in one of the late-game dungeons, allowing you to sneak through tiny holes and stealth past enemies. Some enemies can also turn your party members into mice during battle.

[[folder:Web Comics]]
* In ''Webcomic/ElGoonishShive'', Grace can turn completely into a squirrel.
** Ellen once turned herself into a duplicate of the family cat, "Brownie". She could still talk via magic and retained her mind.
* In ''Webcomic/{{Zoophobia}}'', shapeshifters can change into different animals. Avians into birds, serpentines into snakes and so on.
* All four members of ''Webcomic/{{Panthera}}'' can turn into [[PantheraAwesome big cats]]. Useful enough in itself, but they can also use ElementalPowers while transformed.
* Fletch from ''Webcomic/TheSanityCircus'' can turn at will into a seagull. Other shapeshifters exist in the same world - but overuse leaves you as a FunnyAnimal in the end.
* ''Webcomic/ProfessorAmazingAndTheIncredibleGoldenFox'': Isla Grace receives a fox-shaped engagement ring from her husband-to-be, Parker, which gifts her with the ability to transform into a fox (both anthropomorphic and full fox versions). She then feels it's only appropriate to put her new powers to use in the service of her community.

* Kodotai, Bestiario, Manimal, and Menagerie from the ''Roleplay/GlobalGuardiansPBEMUniverse'' all have the power to assume the shape of any animal species they want. Russian hero Ursa can turn into a giant brown bear. Indian hero Bagha can turn into a large Bengal tiger.
* ''Blog/LimyaaelsFantasyRants'': Limyaael has a rant on [[http://limyaael.livejournal.com/288509.html shapeshifters]], on [[http://limyaael.livejournal.com/290393.html shapeshifter societies]] and on [[http://limyaael.livejournal.com/47942.html blurring the distinction between the "human" part and the "animal part"]].
* In the Literature/WhateleyUniverse, Feral has the power to change into pretty much any predator mammal. There are also [[{{Werebeasts}} Weres]] who can shift into animal or were-animal forms, plus some mutant Shifters can do it. (Some mutants end up stuck in the involuntary version because of the way their power first manifests.)
* Dragore from both Furtopia [=RPs=] of ''Roleplay/DarwinsSoldiers'' was turned into a dragon for unspecified reasons.
** Professor Sehack from the rebooted Furtopia RP was turned into a Bengal tiger for unspecified reasons.
* ''RolePlay/WeAreAllPokemonTrainers'' has both examples:
** Upon entering one of the PMD universes, humans get forcibly transformed into Pokémon.
** A human wearing a human to Pokémon armband will get turned into the Pokémon they relate to most.
** Weremons tend to have involuntary transformations, but due to her enchanted Moon Stone Crewe can switch forms at will.
* [[MeaningfulName Qrow and Raven]] from ''WebAnimation/{{RWBY}}'' have the power to shapeshift into birds. Notably, they have this power ''on top'' of their Semblances of causing bad luck or ThinkingUpPortals respectively, when most people in this setting only have one power.

[[folder:Western Animation]]
* Beast Boy from ''WesternAnimation/TeenTitans'' has this as a special power. Interestingly, the involuntary subtrope occurs in the episode "Bunny Raven, Or How to Make a Titanimal Disappear". Mumbo the Magician changes the Titans into [[TransformationConventions various animals]]. Beast Boy is rendered only able to change into inanimate objects, with a lamp as his base form.
** In WesternAnimation/YoungJustice, Beast Boy also has this ability, presumably due to the blood transfusion from the shape-shifting Miss Martian. Though he can take any animalsí form, he goes with various primates most often, because they are his favourite animals. Since he was bitten by a monkey shortly after said blood transfusion, his default form is that of a green, stooped, tailed half-monkey boy. The latter may just be a voluntary disguise, as a traumatic reminder in one episode caused him to involunarily shift(back?) to a green, but otherwise completely human form.
* Jayna of the Wonder Twins from ''WesternAnimation/{{Superfriends}}''. When the twins touched, Zan could turn into some form of water/ice, while Jayna could transform into any sort of animal.
* The Monkey Talisman in ''WesternAnimation/JackieChanAdventures''. The owner can turn him/herself or others into any animal they can think of.
* ''WesternAnimation/WildKratts'' has this as the founding concept, in which the main characters can assume animal shapes using the AppliedPhlebotinum in order to get close to the real animals.
* Replicon from ''WesternAnimation/SkysurferStrikeForce'' can turn into various animals or even certain attributes of animals.
* In the first episode of the original ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'', Bebop and Rocksteady volunteer to let Shredder turn them into a warthog and rhino, respectively, to get revenge on the turtles for humiliating them.
* In ''WesternAnimation/{{Visionaries}}'', the main characters are fourteen knights who have been given the ability to transform into the animals which best reflect their skills and personalities. For example, Feryl can transform into a Wolf because of his "amazing tracking skills", Leoric can transform into a Lion because of his "raw courage and leadership"... and so on.
* In ''WesternAnimation/TheFairlyOddParents'', Cosmo and Wanda (along with all fairies) can and have done this on numerous occasions, and in fact their base form is a pair of goldfish.
** In at least 5 episodes, Timmy has been able to do this on several occasions.
* In ''WesternAnimation/TheMagicSchoolBus'' episode "In The City", Ms Frizzle turns the students into different animals that you might find in a city, such as foxes, falcons and possums, and herself into a raccoon.

!!Examples of Involuntary Animorphism

[[folder:Anime & Manga]]
* In ''Anime/TheCatReturns'', Haru is turned into a [[CatGirl humanoid cat]] so she will make a more suitable bride for the cat prince.
* In ''Manga/FullmetalAlchemist'', it's possible to combine human beings with animals to create chimeras. If the procedure comes out right, the creature should have human intelligence and several traits from the animal they're mixed with (both advantageous and drawbacks), and some can even shift from their half-animal form to an apparently normal human. They are kept a secret from the public because of the obvious ethical issues they pose (let's just say the subjects did ''not'' volunteer for the experiments). So far we have seen snake, lizard, bull, dog, lion, toad and monkey chimeras.
* In ''Anime/DragonBallZ'' there are a couple of notables. Captain Ginyu, of course, is turned into a frog when Goku interrupts his attempt to swap bodies with Vegeta by tossing a frog in the way. Saiyans with tails will, when looking at the full moon, turn into very large apes. Also inverted during the 22nd Tenkaichi Budokai, when we meet Man-Wolf. He was a humanoid wolf who turned into a human during the full moon. When Jackie Chun previously blew up the moon, it left him stuck in wolf form, and quite angry about it. So, Jackie hypnotizes him into his human form permanently.
* In ''LightNovel/BludgeoningAngelDokurochan'' Dokuro has a bad habit of doing this to students who get in the way between her and Sakura. One she turns into a baboon, the other an Shiba dog. No one seems to care. Made extra-funny by how they render the change: replacing the characters heads with paper cutouts, as seen [[http://www.youtube.com/watch?v=EQD2yeX_P2k here]].
* One chapter of ''Manga/ToLoveRu'' and one chapter of ''[[Manga/ToLoveRu To Love-Ru Darkness]]'' are devoted to this, Rito being turned into a dog and found/petted by Haruna in the first one, and [[IronicEcho Haruna being turned into a cat and found/petted by Rito]] in the second.
* Some characters in ''Manga/RanmaOneHalf'' are cursed to transform into animals when doused with cold water. We get to see a giant panda, a cat, a piglet, a goose and a yeti-bull-crane-eel-octopus hybrid. The degree of "involuntary" varies, though.
* In ''Anime/NegimaSecondSeason'' the spinoff series of ''Manga/MahouSenseiNegima'', Negi Springfield is turned into a "chupacabra" due to [[BrokenMasquerade revealing the existence of magic to most of the class during the final episode]].

[[folder:Comic Books]]
* ComicBook/{{Thor}} was turned into a frog once because of a curse by Loki.
* As mentioned above in WesternAnimation, the Lizard.

[[folder:Comic Strips]]
* ''ComicStrip/CalvinAndHobbes'' happily plays with the CursedWithAwesome aspect of this Trope at least twice, via Calvin's Transmogrifier.
** In one story, Calvin is turned into an owl and isn't pleased -- until he remembers that owls don't go to school and so he and Hobbes can play in the woods all day. [[spoiler:And then, next morning, he learns that the effects of the Transmogrifier wear off overnight]].
** At the end of the story arc where Calvin clones himself several dozen times, he ends up transforming the clones into worms. And their immediate reaction, rather than being seriously upset, is "Cool! Look at us! Let's go gross someone out!"
** Another instance is he once used the Transmogrifier to turn into a tiger, which he ends up looking like a smaller version of Hobbes.

[[folder:Fan Works]]
* In the ''WesternAnimation/LittlestPetShop2012'' fanfic ''Fanfic/BlythesLittleProblem'', Blythe Baxter transforms into a cat and only has four days [[AndIMustScream to turn back to normal before it would become permanent...]] and then [[spoiler:Sue Patterson turns into a ferret.]]
* The ''Literature/HarryPotter'' fanfic ''FanFic/WaterAreobicsForTheAquaphobic'' has the entirety of Hogwart's year four to seven student population (except for Luna), the accompanying teachers, as well as [[BigBad Voldermort]] and his Death Eaters cursed with the [[Manga/RanmaOneHalf Jusenkyo curse]] after a field trip to the [[MeaningfulName Jusenkyo Cursed Springs]], causing them to transform into The-Drowned-Something-Or-Other of the spring they fell in, mostly animals, whenever doused with cold water. HilarityEnsues.
* Blade Star in ''FanFic/MyFamilyAndOtherEquestrians'', and later Lizzie in Interlude 9 (Discord might be behind that last one).
** Lizzie's case becomes an example of Voluntary Animorphism, as Lizzie eventually wants to stay a pegasus when she is given the choice to change back.
* In ''Fanfic/TheUndesirables'' [[spoiler:Sonata Dusk]] is turned into a pony upon entering Equestria due to the events of [[spoiler:''[[WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks Rainbow Rocks]]'' rendering her as fully human]].
* In ''Fanfic/WhatTheWaterGaveMe'', Hicup pleads to "the Water" to [[spoiler:save a mortally wounded Astrid]]. His prayers are answered when [[spoiler:Astrid is turned into a mermaid]].

[[folder:Films -- Animation]]
* Lampwick and the other boys partying on Pleasure Island literally [[TransformationTrauma make asses out of themselves]] in ''Disney/{{Pinocchio}}''.
* In ''Disney/BrotherBear'', your spirit evidently takes the form of your totem animal (good news if your totem is an eagle, [[FridgeLogic maybe not so much if your totem is a salmon]]). The protagonist Kenai is turned into a bear by the spirits to teach him a lesson. [[spoiler:Kenai eventually gets over his [[CursedWithAwesome angsting over being transformed]] and opts to stay a grizzly and adopt the cub Koda as his little brother.]]
* ''Disney/TheEmperorsNewGroove'': Izma has a number of potions able to transform a human into an animal, as well as a potion for turning animals human. This is how Kuzco gets stuck as a llama for the majority of the film. Late in the movie, a number of castle guards get random potions dumped on them. [[spoiler:In the end, Izma herself is trapped in the form of an adorable kitten.]]

* In ''WesternAnimation/HelpImAFish'', the three main characters accidentally get turned into fish after drinking a potion made by [[AbsentMindedProfessor Professor MacKrill]].

[[folder:Films -- Live-Action]]
* ''Film/CatPeople'' has werecats who are the distant offspring of black leopards with their human worshipers. Transformation is invoked by [[DeusSexMachina carnal relations]].
* The short story ''Literature/TheFly'' and its two [[Film/TheFly1958 movie]] [[Film/TheFly1986 adaptations]] are a high-tech and [[TransformationTrauma horrific]] version of this, where either a man and a fly exchange heads, or a man slowly becomes a fly.
* In fact, this is a staple of horror and sci-fi films from the era, as evidenced by the titles ''Film/TheAlligatorPeople, The Ape Man, The Bat People, The Brooklyn Gorilla'', ad infinitum...
* Quite a few of the characters in ''Film/{{Stardust}}'' get turned into animals under a number of different circumstances. A farmer is turned into a goat by the wicked witch - and then on top of that [[spoiler:she changes him back into a human later. A '''[[GenderBender female]]''' human! If that's not enough, she turns another [[HumanityEnsues goat into a man]] to act as his/her father]]. The protagonist is turned into a dormouse by another witch, but only because he's easier to carry in her wagon this way and she changes him back as soon as they reach their destination. Finally, a fairy woman changes into a jay and back, though it's not made clear if this is under her own power or not - there are a lot of [[IAmYourFather odd things]] going on with this character.
** The book makes it quite clear that the fairy woman's shapeshifting is involuntary. This probably applies to the film as well.
* "[[Film/MontyPythonAndTheHolyGrail She turned me into a newt]]!"
** "I got better!"
* In ''Film/TheThiefOfBagdad'', Abu the thief is changed into a dog by the wicked Jafar. Curiously, he adjusts rather well to his new life, accompanying his blind friend as a dog guide.
* In the movie adaptation of Roald Dahl's ''Literature/TheWitches'' Bruno, and the protagonist are both turned into mice, as are all the witches at the end, very creepily losing the bulk of their mass like escaping steam.

* One of the first stories of Creator/{{Ovid}}'s ''Literature/{{Metamorphoses}}'' involves the transformation of Io into a white cow. Considering that this story was old by the time Ovid recounted it, this one is definitely OlderThanFeudalism.
** The book also shows examples of VoluntaryShapeshifting and almost every other ShapeShifting trope - it ''is'' right in the title after all.
* And another set of ''Metamorphoses'', this one by Apuleius (second century CE), involves a young man, Lucius, who experiments with a witch's charms in her absence and ends up as a donkey.
* Creator/FranzKafka's ''Literature/TheMetamorphosis''; the protagonist has transformed into a bug (literally "vermin"), possibly a beetle. If that's true, it adds a layer of irony to his death: he could've flown away, if he only knew...
* In Literature/TheSookieStackhouseMysteries, Sookie's roommate Amelia turns fellow witch Bob into a black cat during a night of wild sex.
* ''Literature/TheDresdenFiles'': Using magic to transform someone else against their will is against the laws of magic, but possible. The [[{{Werewolf}} Loup-Garou]] from ''Literature/FoolMoon'' is subject to a hereditary curse which causes the afflicted to transform into a nigh-invincible wolf monster and go on a rampage during a full moon.
* The Librarian of ''Literature/{{Discworld}}'''s Unseen University was transformed into an orangutan early in the second book, ''Discworld/TheLightFantastic'', by an exceptionally powerful spellbook. (Books on magic are dangerous as they are, but this one belonged to the Disc's Creator) He has since come to enjoy his new state, as the prehensile toes make shelving a dream, and the muscles capable of unscrewing someone's head off. (Which [[BerserkButton he will do]] if you call him a [[IAmNotWeasel monkey]]) The other wizards allow this because he's the only one who can run the library, and there's [[LoopholeAbuse no rule]] against an ape serving on the college council (and the wizards looked very hard for one).
** The Toad in the Tiffany Aching books is actually [[spoiler:a lawyer]] who got on the wrong side of a fairy godmother, and subsequently got on the right side of the Nac Mac Feegle. The Disc will never be the same again.
* ''Snow White and Rose Red'', a fantasy novel adaptation of [[Literature/SnowWhiteAndRoseRed the fairy tale of the same name]], reveals this as the fate of a Faerie who loses their magical essence. Thus, when Hugh is robbed of his essence by humans seeking to master Faerie magic, he slowly and painfully turns into a bear over the course of a month. Furthermore, anyone who fully transforms gets unceremoniously dumped out of the realm of Faerie and banished. Hugh's curse serves as the conflict of the novel, and [[TheMindIsAPlayThingOfTheBody his loss of humanity]] as time passes in the bear's form becomes another source of problems.
* Magnus Bane from ''Literature/TheMortalInstruments'' can turn into a cat.
* In Roald Dahl's ''Literature/TheWitches'' a greedy second banana named Bruno, and the protagonist are force fed "Formula 86 delay action mouse maker" by the witches, and subsequently forced to foil their plot as tiny field mice. By turning them all into mice.
* Arthur Yorink's picture book ''Louis the Fish'' is about a man who has inherited his family's butcher shop, but hates meat. His fascination with fish is the only source of joy in his life. He falls ill and one night has an extremely bizarre dream. When he wakes up, he has been inexplicably transformed into a salmon. This doesn't bother him and when the owner of the local pet shop puts him in an aquarium, he is happy to live the rest of his life as a fish, [[TheMindIsAPlaythingOfTheBody soon forgetting that he was ever human]].
* In ''Literature/TheBelgariad'', TheBigGuy Barak is appointed by Prophecy to be Garion's protector, with the side effect that he occasionally turns into a [[BearsAreBadNews large, angry bear]] when Garion is in danger. Before he learns what triggers the transformation, he's terrified of eventually degrading into a mindless beast; later, he comes to think it's pretty neat, though the fact that he's at ''least'' as dangerous a fighter in human form makes it mostly AwesomeButImpractical.

[[folder:Live-Action TV]]
* In ''Series/BuffyTheVampireSlayer'', Amy, the witch, turns herself into a rat to escape an angry mob. This is on the involuntary list because she can't change herself back - as a rat, she has no powers. Amy first used her rat spell in an earlier episode on Buffy, which she later reversed.
** After witnessing this, Willow and Buffy try to frighten the mob into letting them go.
-->'''Buffy:''' Yes! You will all be turned into vermin. And some of you will be fish! Yeah, you in the back will be fish!
* ''Series/{{Merlin}}'' had Freya, the Druid girl cursed to transform into a panther, albeit a winged one, every night at midnight.
* One of the films shown on ''Series/MysteryScienceTheater3000'', "Jack Frost", was a bizarre pastiche of nearly every Fairy Tale Trope imaginable. In one of the many plot threads, the hero is turned into a bear - and he spends nearly the entire first half of the movie complaining loudly about this.
* One of Sam's leaps on ''Series/QuantumLeap'' was into a chimp at NASA.
** However, it should be noted that Sam leaps into people's ''auras'', not their bodies, so all the other characters see a completely different character. Sam can, in fact, stand perfectly upright in the episode, but after a scientist remarks that this is unusual for a chimp he spends the rest of the episode hunched over.
* Happens twice on ''Series/MythQuest'', in different myths.
** Thor turns Váli into a wolf so he will attack his brother.
** Math and Gwydion turn Blodeuwedd into an owl as punishment for killing her husband.
* Series/{{Woof}}!, which features a kid who [[InvoluntaryShapeshifting involuntarily]] changes into a dog at times.

* The man of fortune in Music/CaroleKing's Music/{{Tapestry}} is turned into a toad.

* In ''Toys/{{Bionicle}}'', [[spoiler:Metus is transformed into a snake by the Mask of Life.]]

[[folder:Video Games]]
* ''Vivisector: Beast Within'' deals with Doctor Moreau-like half-human animal cyborgs, but there's also hints that their creators also did something to the game's protagonist as a kid, which manifest during the events of the game.
* Glenn the Frog of ''VideoGame/ChronoTrigger'' was transformed by the BigBad. Given the some of Frog's skills explicitly take advantage of his new shape (water magic, grabbing enemies with his tongue, twenty-foot leaps,) this falls square into CursedWithAwesome.
* ''VideoGame/MarioAndLuigi'' features an early game boss fight with a dragon that hatched from a giant egg. After defeating the dragon, it turns back into main character Prince Peasley, who reveals that Cackletta turned him into the dragon and trapped him inside the egg to get him out of their way.
* In the adventure game ''VideoGame/{{Loom}}'', the ultimate punishment tor Spellweavers -- "Transcendence" spell -- involves transformation into a swan.
** The manual explains how the protagonist's mother got transformed shortly after his birth.
** His foster mother gets transformed into an egg shortly after the game start (the spell went wrong). Later she hatches as an adult duck.
** Immediately after she becomes an egg, a swan appears and transforms into swans the whole village except the protagonist.
* In ''VideoGame/QuestForGloryI'', Baba Yaga turns you into a frog, and the Dryad will turn you into a white stag [[YetAnotherStupidDeath if you offend her]].
** One should [[TheManyDeathsOfYou expect nothing less]] from a Creator/{{Sierra}} game.
* Three cases of this happen in the ''Franchise/JakAndDaxter'' series :
** At the beginning of the first game, Daxter is turned into an ottsel after being knocked back into a pool of Dark Eco by accident. The plot of the game is to find a way to change him back into a human, though in the end, [[spoiler:he is forced to give up his chance to allow Jak to defeat the Big Bads]]. He has since accepted his new form.
** Near the end of the third game, [[{{LightIsNotGood}} Count Veger]] demanded that he'd be transformed into a Precursor when Jak is given the chance. [[spoiler:One [[TheReveal reveal]] later, he's stuck as an ottsel and at the mercy of Kleiver]].
** At the end of the third game, [[spoiler:Tess is turned into an ottsel when she wishes she had pants like the ones Daxter just got]].
* Thanks to her greed, Aire from ''VideoGame/FinalFantasyThe4HeroesOfLight'' gets cursed into a cat form.
* In ''VideoGame/PattyAndMrMiles'', all the men in Rinu Village have their heads turned into various animal's heads thanks to a witch's curse.
* One of Lulu's abilities in ''VideoGame/LeagueOfLegends'' turns enemies into small fluffy animal temporarily, leaving them unable to attack or use their own abilities until it wears off.

[[folder:Visual Novels]]
* Sasami's route in VisualNovel/LittleBusters involves this, as she'll transform into a cat if she isn't inside Riki's room. She'll still transform into a cat inside Riki's room if someone besides the two of them is in the room and is also conscious.

[[folder:Web Comics]]
* In ''Webcomic/TheOrderOfTheStick'', Vaarsuvius is temporarily changed into a lizard.
* Zoe from ''Webcomic/SluggyFreelance'' is in something of a grey area between voluntary and involuntary shapeshifting. The magic tattoo on her neck causes her to transform into a camel whenever someone says "shupid" near her, and it changes her back when someone says "kwi." Technically, Zoe could say "shupid" and turn herself into a camel, but this is pretty unlikely since she doesn't like transforming and, in camel form, she can't say the magic word to change back.
** She did it once, when she needed to hide fast and a random camel in a closet wouldn't raise eyebrows.
* In ''Webcomic/KevinAndKell'', the portal from Earth to Furth transforms humans into appropriate animals. [[spoiler:Except Martha, when she was hiding in a lead-lined barrel.]]
* An apparent running gag in ''Webcomic/ElectricWonderland'' involves Aerynn turning NJ into a random animal whenever she needs help protecting herself and/or their teammates.
* In ''Webcomic/ElGoonishShive'', Dan once turned Melissa into a cat in a filler strip (which got carried over into a later filler strip).
** In an AprilFools strip, the cast was turned into cats at one point
** In the BackStory (but entirely canonical), Tedd once turned Sarah into a cat by mistake.
* An interesting example happens in ''Webcomic/CrimsonFlag'', where the normally anthropomorphic fox characters are turned into normal foxes. This is more going from a [[PettingZooPeople Petting Zoo Person]] to a normal animal.
* One plotline in ''Webcomic/DarwinCarmichaelIsGoingToHell'' has Ella transformed into a cat by a magic hat. Turns out there's a man running a street theater show with involuntarily transformed anthropomorphic animals.
* ''Webcomic/ProfessorAmazingAndTheIncredibleGoldenFox'': Isla Grace receives a fox-shaped engagement ring from her husband-to-be, Parker, which gifts her with the ability to transform into a fox (both anthropomorphic and full fox versions). She then feels it's only appropriate to put her new powers to use in the service of her community.

* The entire basis for the ''WebOriginal/{{Paradise}}'' setting is the involuntary (and invisible) transformation characters go through into {{Funny Animal}}s.
* Professor Crow from ''Wiki/SCPFoundation'' was turned into an intelligent dog, presumably by a lab accident.

[[folder:Western Animation]]
* In the ''WesternAnimation/KimPossible'', episode "The Full Monkey", Lord Monkey Fist curses Kim with a magic amulet, which causes her to develop a monkey-ish physique... on school picture day. Monkey Fist himself is part monkey due to radical experimentation.
* ''WesternAnimation/JackieChanAdventures'':
** It features the Monkey Talisman which allows the user to transform any object (living or not) into any animal (except transforming stone or rocks would create animal statues instead) and back again. Whether voluntary or not usually depended on the situation.
** Jade also suffered two additional transformations during the series, once turning into a cat person after being scratched by a magical artifact, and another time turning into a donkey due to a chaotic spirit.
* ''WesternAnimation/AmericanDad'''s Klaus is an East German Olympic ski jumper, semi-permanently placed in the body of a goldfish. Apparently, the fish got his body in the deal, but couldn't use it.
* ''WesternAnimation/TheFairlyOddParents'': Cosmo and Wanda frequently turn into animals to disguise themselves to keep up the {{Masquerade}}. No one seemed to care or even notice that their fur/plumage is green and pink.
** One episode had Timmy trading brains with a dog, only to find himself unable to change back, since the fairies couldn't speak Dog.
* ''WesternAnimation/TotallySpies:'' Clover gets turned into a CatGirl in one episode.
** In the Crossover Episode between ''WesternAnimation/TotallySpies:'' and ''WesternAnimation/MartinMystery:'' they all went through at least partial transformations into Yeti.
* In ''WesternAnimation/TheSpectacularSpiderMan'', [[EvilutionaryBiologist biologist]] Curtis Connors pays the price for using himself as a [[ProfessorGuineaPig guinea pig]] for a [[JustThinkOfThePotential limb-regenerating]] [[LegoGenetics formula]] made from [[GeneticEngineeringIsTheNewNuke genetically modified]] lizard DNA. He regains his right arm, but then {{transform|ation trauma}}s into the Lizard, an [[ReptilesAreAbhorrent unthinking humanoid reptile]]. He only returns to normal after Spider-Man force-feeds him an [[PowerNullifier antidote]], [[NoOntologicalInertia losing the new arm]] in the process.
* Even though the title characters don't count, in the [[WesternAnimation/TeenageMutantNinjaTurtles1987 80's Teenage Mutant Ninja Turtles cartoon]], April O'Neil had undergone a few involuntary transformations, including a {{cat| girl}} and a {{fish| people}}.
** And while the turtles themselves don't count, their master Splinter does, as the same ooze that turned them into humanoid turtles turned him, formerly a ninja master named Hamato Yoshi, into a humanoid rat.
* Baxter Stockman turns into a fly when entering a portal at the same time an actual fly does.
** The ooze does this in [[WesternAnimation/TeenageMutantNinjaTurtles2012 the 2012 series]]. It seems that the ooze turns a person into an animorphized version of whatever living thing ([[{{Transflormation}} plants included]]) that they were last in contact with. (excluding mutants)
* ''WesternAnimation/BeastWars'' inverted a large part of the trope. Where most heroes use animal forms to become stronger, these Transformers use them to mainly protect themselves from local radiation, and can only spend limited time in the "human" (humanoid robot) form that has the real power: their [[MoreDakka guns]].
* In the ''WesternAnimation/PhineasAndFerb'' episode ''Does This Duckbill Make Me Look Fat?'' Candace and Perry get their minds swapped by a teleporter mishap.
-->'''Candace:''' Am I sweating milk?
* In the ''WesternAnimation/DefendersOfTheEarth'' episode "Dracula's Potion", the titular potion transforms all the Defenders except the Phantom into the animals which best reflect their personalities.
