** The villain Captain Ginyu in ''Anime/DragonBallZ'' (who has the ability to switch bodies with his opponents) is defeated when he is tricked into switching bodies with an ordinary, powerless Namekian frog. When the planet he is on explodes, he is transported along with everybody else to Earth, and stays on Earth, along with the frog now inhabiting his old body, until the planet is destroyed by Kid Buu. In an anime filler, he manages to switch bodies with Bulma, but is soon forced back into his frog body.

[[spoiler:In ''Anime/DragonBallSuper''[='s=] adaptation of ''Anime/DragonBallZResurrectionF'', Ginyu is alive and well and is able to switch bodies with Tagoma, trapping him in the frog body, but ultimately becoming a HoistByHisOwnPetard moment for Ginyu as Vegeta, now a Super Saiyan God Super Saiyan, easily kills Ginyu while telling him he shoulda stayed in the frog]].

* One chapter in ''Manga/{{Doraemon}}'' had "Animal Biscuits/Transformation Crackers", which were animal-shaped biscuits that turn anyone who eats them into an animal based on what biscuit they ate[[note]]for instance, eating a cat-shaped one would turn you into a cat[[/note]].
* The ''Doraemon'' NonSerialMovie, ''Anime/DoraemonNobitasGreatAdventureIntoTheUnderworld'', have the new heroine, Miyako, being cursed by the forces of darkness and turned to a cat, though she can transform back to human form after getting exposed to moonlight. The 2007 remake spices things up a bit by having Miyako becoming a mouse instead, which results in some comedic moments when she tried communicating with Nobita and Doraemon in mouse form, since [[WhyDidItHaveToBeSnakes Doraemon happens to be deathly afraid of mice]].

* In ''LightNovel/{{Campione}}'', when Sun Wukong manifests on Earth, all non-magical humans in the surrounding city are transformed into monkeys. Notably, this is not out of malice but primarily because Sun Wukong desires subjects to rule over; the transformed civilians are unharmed and eventually return to normal.

* In ''LightNovel/{{Dokkoida}}'', Hyacinth's henchman Pierre has the ability to morph into almost any animal when whipped. The animal is always random, and never anything useful. However, in the past (i.e. before the start of the series) he morphed into animals that were quite threatening indeed, leading to Hyacinth's status as an A-class villain.

After being trapped in that form for two years, he's mainly reduced to growling and roaring despite the fact that he can speak, and is hunted by the Thule Society in an effort to open the Gate. [[spoiler:In the end, he murders Hohenheim and simultaneously kills himself without ever changing back]].

* The titular girl in ''Manga/CaterpillarGirlAndBadTexterBoy'', Suzume Kikuo, was transformed into a giant caterpillar out of misery. The rest of the story is trying to figure out how to turn her back.
* In ''LightNovel/{{Dokkoida}}'', Hyacinth's henchman Pierre has the ability to morph into almost any animal when whipped. The animal is always random, and never anything useful. However, in the past (i.e. before the start of the series) he morphed into animals that were quite threatening indeed, leading to Hyacinth's status as an A-class villain.
* In ''Manga/DoctorSlump'', the morph gun that Senbei invents can cause this effect on its target, by changing said target into whatever the user says the target would become while pointing it at said target. It's also the reason that Senbei and Arale are stuck as flies in a three-part story arc.[[note]]Because Senbei and Arale are turned into flies and [[ExtremeOmnivore one of the Gachans]] devours said morph gun before it can be used to turn them back to normal, they have to remain as flies until [[BrainyBaby Turbo]] can make another one, which Turbo admits will take a day. Arale, being a NighInvulnerable FunPersonified RobotGirl, doesn't mind, as she's glad that she gets to fly for once. Senbei, on the other hand, is not happy, as he can't sleep beside Midori, his HappilyMarried wife, lest she crushes him with her body (he has to sleep inside an empty matchbox, placed beyond Midori's reach, instead) and is forced to watch over his own back for any animal that would prey on flies (he gets stuck in a spider web at one point and would have been dead had Midori not been around to get him out of it before a spider reaches him, and he has to run -- er, fly -- for his life upon spotting a gecko nearby), ensuring that he'd be relieved upon being turned back to human, unlike Arale, who finds it boring to be turned back to normal.[[/note]]
* One chapter in ''Manga/{{Doraemon}}'' had "Animal Biscuits/Transformation Crackers", which were animal-shaped biscuits that turn anyone who eats them into an animal based on what biscuit they ate[[note]]for instance, eating a cat-shaped one would turn you into a cat[[/note]].
* Transformation is a very common type of magic in ''Manga/{{Dorohedoro}}''. One of the first antagonists in the series is a young magic user who can turn people into bugs; he's not very good at it though, so they usually just end up with their limbs replaced with nonfunctional insect legs. Other, more skilled transformation-users also feature prominently.
* ''Franchise/DragonBall'':
** The villain Captain Ginyu in ''Anime/DragonBallZ'' (who has the ability to switch bodies with his opponents) is defeated when he is tricked into switching bodies with an ordinary, powerless Namekian frog. When the planet he is on explodes, he is transported along with everybody else to Earth, and stays on Earth, along with the frog now inhabiting his old body, until the planet is destroyed by Kid Buu. In an anime filler, he manages to switch bodies with Bulma, but is soon forced back into his frog body.
** Speaking of Bulma, she is on the receiving end of the switching bodies with Ginyu Frog in ''Z''. There was also the time the Rabbit Boss turned her into a carrot in the original ''Manga/DragonBall''.
** In the final saga, Majin Buu regularly turns people into candy to eat them and absorb their powers. Eventually, he even turns Vegito into a candy ball. [[SubvertedTrope Said candy proceeds to kick Buu's ass]]. Buu, considering Vegito to be even more dangerous as what basically amounts to an absurdly powerful living bullet,[[note]]Note that reducing the surface area of an object while not reducing the force it exerts increases the pressure, hence doing more damage. Yay, physics![[/note]] decides to change him back. Now ''that's'' entertainment.
--->'''Vegito:''' I'm no ordinary candy! I'm a jawbreaker, the strongest candy there is!
*** PlayedForDrama when Buu turns Chi-Chi into an egg before stomping her to pieces, to the horror of everyone present.
* ''Manga/FairyTail'':
** In Chapter 23, Natsu gets turned into a small lizard and trapped under a glass so he won't go on a RoaringRampageOfRescue when Erza is put on trial by the Council. [[spoiler:But it turns out the lizard is actually Macao, who turned himself into a lizard and pretended to be a captured Natsu so that he ''could'' go rescue Erza.]]
** An AllThereInTheManual example with Kinana: she was turned into a snake ten years ago and made to fight alongside Cobra, until Marakov turned her back. She doesn't have any memories of being a snake.
** In chapter 491: [[spoiler:Irene transforms Princess Hisui into a mouse]].
** In the [[Manga/FairyTail100YearsQuest sequel series]], after being defeated and captured by the servants of the Moon Dragon God, Selene, [[spoiler: all of Team Natsu, save for Natsu and Gray, are transformed into yokai by Selene's servant Youko. Specifically, Lucy becomes a [[SnakePeople nure-onna]], Erza a [[TsuchigumoAndJorogumo jorogumo]], Wendy a [[BakenekoAndNekomata bakeneko]], and Happy and Carla both become [[PantheraAwesome suiko]].]]
* In ''Manga/FruitsBasket'', the story centers around a family with a curse that turns thirteen of its members into animals from the EasternZodiac (plus the Cat) whenever they're embraced by someone from the opposite gender who isn't cursed themselves, though luckily they can still talk and will eventually turn back (but expect an awful lot of [[ShapeshiftingExcludesClothing awkwardness]]). While turning into an animal may seem fun on paper, it's still clearly a ''curse'' since it prevents the afflicted from forming relationships outside of the family and many of their parents reject them because of their cursed status.
* Envy in ''Anime/FullmetalAlchemistTheConquerorOfShamballa'', gets stuck as a dragon due to ShapeshifterModeLock [[spoiler:from going through the Gate into a world without alchemy]]. After being trapped in that form for two years, he's mainly reduced to growling and roaring despite the fact that he can speak, and is hunted by the Thule Society in an effort to open the Gate. [[spoiler:In the end, he murders Hohenheim and simultaneously kills himself without ever changing back]].
* In ''Manga/{{Gintama}}'', a story arc focuses on Gintoki, Katsura, and Kondo trying to return to their original forms after they're cursed as a result of relieving themselves on a cat's grave. The former two transformed into cats, while the latter of the three inexplicably ends up as a gorilla instead (Befitting of his nickname). Despite the change, they're still able to beat up the ones responsible for capturing Kabukicho's stray cats rather easily, though in Kondo's case, it's more than justified.
* ''Anime/GrimmsFairyTaleClassics'' provides plenty examples:
** The witch from "The Six Swans" turns her royal husband's six sons into swans with cursed white capes. Their sister must make six other capes to break the curse, which the swans manage to put on when they come to rescue her and bring her kidnapped son back.
** The prince in "Snow White and Rose Red" caught the wicked gnome stealing the castle's treasures and got turned into a bear for his trouble. He didn't recover his human form until he managed to kill the gnome.
** Rudolf in "Brother and Sister" was turned into a Deer when he drank water from a pond that was enchanted by his and Rose's evil Step-Mother.
** The prince's subjects in "The Iron Stove" were turned into mice by the Hot Witch. After the Witch is given a Disney Villain Death, they're released.
** "The Old Woman in the Woods" turned a prince and his subjects into animals, with the Prince himself stuck in an owl's form, and those that trespass in the witch's neck of the forest are turned into trees. The only one who escapes this is the maid Lisbeth, and the Owl Prince first protects her and then recruits her to kill the witch.
** In "The Magic Heart", a huntsman finds a cabbage garden of two different types. One kind of cabbage turns those who eat them into donkeys, the other kind returns the donkeys to their human forms. He used these cabbages to get revenge on an old witch and her daughter Lisbeth for treating him like crap, though later he uses another to return Lisbeth to her human form.
** In "Jorinde and Joringel", a Wicked Witch who hates happy couples in love turns the titular Jorinde into a bird. Her boyfriend Joringel has to rescue her.
* Tomoe from ''Manga/KamisamaKiss'' likes to transform an opponent into a game animal of some kind and then try to cook them alive.
* In one episode of ''Anime/TheLegendOfSnowWhite'', Snow White's pets accidentally turn her into a rabbit with magic dew that they think will just make her understand their speech.
* In a story of one the ''Anime/MazingerZ'' manga versions, a race of giant, man-eater, fish-alike, humanoid {{Eldritch Abomination}}s from another dimension named Chip Kamoy tried to invade Earth. They kidnapped a normal human girl and transformed her into a mermaid-like being to communicate with humans. Later they trapped TheHero Kouji Kabuto and she helped him to escape. In punishment [[spoiler:she got executed by the Chip Kamoy.]]
* ''Manga/NegimaMagisterNegiMagi'':
** Referenced. The penalty for flagrantly breaking TheMasquerade is getting turned into an ermine. This ''may or may not'' be the case with [[WeaselMascot Chamo]].
** In ''Negima!?'', Negi does [[spoiler: get turned into a {{chupacabra}}]], but he gets better.
* In ''Manga/NyanKoi'', Junpei will turn into a cat (which pretty much kills him, since he's allergic) if he doesn't perform one hundred good deeds for cats.
* Any Witch in ''Anime/OjamajoDoremi'' is turned into a Witch Frog whenever a human calls them a Witch. They can be changed back, but only the one who called them can pull it off. Unfortunately, most humans run away in fear when it happens, leaving many unfortunate Witches trapped in that form for the rest of their lives. It's even implied that most Witches never return to normal. [[spoiler:Averted later on when the curse the causes the Baleful Polymorph is lifted by the one who originally cast it in the first place; it still came too late for those who died as witch Frogs.]]
* In ''Manga/OnePiece'', the samurai Kin'emon's missing son Momonosuke ate an artificially created Devil Fruit that turned him into a little eastern style dragon. Whether due to his inexperience with Devil Fruit powers or problems with the man-made fruit itself, Momonosuke has trouble transforming back to human form.
** The Dressrosa arc introduces Sugar, a member of the Doflamingo pirate crew. She has eaten the Hobby-Hobby fruit, which grants her the ability to turn people into toys and even [[{{Unperson}} remove people's memories of them]]. Though this comes with a trade-off that she's stuck in the physical body of a ten-year-old girl. Actually, even ''that'' [[BadassAdorable doesn't come as a disadvantage]].
* ''Anime/PokemonTheSeries'':
** Ash Ketchum gets turned into a Pikachu at the end of an episode thanks to a rather careless magic spell coming from a CuteWitch they've been helping. [[CursedWithAwesome Luckily for him]] it only lasts for a while, and he seems to be thrilled to be able to freely play with his Poks. (Unluckily for the audience, we barely see him do anything in this time -- the next episode starts with him returning to his human form).
** ''Pokémon'' also has Sabrina, who while suffering from Literal Split Personality turns some people [[AndIMustScream into dolls]] with her psychic powers.
* In ''Manga/PokemonMysteryDungeonGinjisRescueTeam'' (an adaptation of the below-mentioned ''VideoGame/PokemonMysteryDungeonRescueTeam''), a boy named Ginji falls asleep and wakes up in another world turned into a Torchic. It ends with him inexplicably turning back into a human. The manga keeps it vague if his adventure was a dream or not.
* Inverted in ''Anime/PrincessTutu''. Ahiru is actually a duck to ''begin'' with and gets turned into a human girl, but certain circumstances will cause her to revert to duck form...
* ''Manga/RanmaOneHalf'', natch. While many of the springs can be CursedWithAwesome or BlessedWithSuck dependent only upon your feelings towards that curse and the situations of your life (Boy/Girl, Panda, Child, etc.), the various little animal springs (like Cat, Duck and Pig) lean pretty heavily towards BlessedWithSuck. Especially seeing as how other springs include [[OneWingedAngel Yeti-Riding-Ox-Carrying-Crane-and-Eel]] and [[PhysicalGod Ashura]].
* In ''Manga/RuinExplorers'', Ihrie turns into a rat every time she uses her magic, a curse from her old master.
* Used in ''Anime/SailorMoon'', when [[spoiler: Wiseman tricks Esmeraude into putting a crown on herself that would boost her powers. It turns her into a mindless dragon instead.]]
* In ''Manga/SgtFrog'', Keroro tricks Natsumi into wearing a dog collar that transforms her into a dog, forcing Natsumi to flee her house as they're not allowed to have pets there. Keroro then follows Natsumi, intending to catch her in the act of doing something embarrassing while stuck as a dog, as she finds herself fighting her canine urges. She fortunately manages to dodge this and finds herself in the care of her crush, before reverting to human form right before him and causing Keroro to zap himself with his own device, causing him to behave like a dog in turn.
* This trope is central to the plot of the [[{{Hentai}} ero-manga]] ''Tentacle Lovers'', wherein a young man is turned into a [[BreadEggsMilkSquick small, cute tentacle monster]] after a foreign princess botches a summoning spell. Played with by the end, wherein the Princess manages to make a ''new'' body for the protagonist, and transfers his soul into it. However, because it was designed from her memory (and the two had several MateOrDie moments), his new form was a bit more... [[BiggerIsBetterInBed endowed]]... than it used to be.
* A RunningGag in ''Manga/ToLoveRu'' is that Rito is constantly getting transformed into different shapes or things, whether they be animals, objects, or different sizes due to Lala's inventions; whether or not it was a malfunction or an accident.
* ''Manga/{{Uzumaki}}'' features some people who transform into snails, and one couple who become snake-like. This isn't too bad for the snailized people until [[spoiler: the un-snailized people start looking for food]].
* In one chapter of ''Manga/{{Superior}}'', Sheila gets turned into a dog (that can only say meow) when Exa tries to teach her healing magic.
* ''Anime/MashinHeroWataruSeries'': Kurama and the rest of his village are humans who were forcibly turned into bird-people by Doakudar. He's mainly working for him in order to undo that. Himiko personally thinks his bird form is cooler than his human one.
* ''Anime/ArabianNightsAdventuresOfSinbad'': Since the setting is based on ''Literature/ArabianNights'', you must expect to come across them quite a lot. Shera was also victim of this. She's a princess transformed into a bird. So are her parents, who got turned into white eagles.
* In ''Manga/ToiletBoundHanakoKun'', whenever Nene is touched by water, she starts to develop mermaid scales on where her skin comes in contact with water, due to her swallowing a mermaid scale. If she is completely submerged or drenched in water, she transforms into a tiny fish.
