History Main / Animorphism

* Kars from ''JojosBizzareAdventure'' 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 ''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.

* Early in the series, Kotaro of ''MahouSenseiNegima'' with his powers sealed revealed the ability to become a small puppy. [[spoiler:Recent events show that he can, at full power, become a [[SuperMode Super-Powered]] BigBadAssWolf.]]

* Druids in ''{{Warcraft}} III'' could turn into the totem animal whose demigod they were devoted to.

* In WhiteWolf's other main RPG, ''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's not ALWAYS human. Alextraza and her consert turn into High Elves, Chronomaru turns into a Gnome, Yersa 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.

* ''{{Manimal}}'' had a main character with transformation into animals as a special ability.
* In 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.

* ''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.

* ''TotallySpies:'' Clover gets turned into a CatGirl in one episode.
** In the Crossover Episode between ''TotallySpies:'' and ''MartinMystery:'' they all went through at least partial transformations into Yeti.
* In ''TheSpectacularSpiderMan'', [[EvilutionaryBiologist biogeneticist]] Curt 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.

* Snowbird from ''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.

* 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.

!!Examples of the Voluntary Animorphism

* Ichigo of ''TokyoMewMew'' is a borderline case. The intended effect of her cat genes is the ability to voluntary transform into a CatGirl; however, as her cat DNA starts to overtake her human DNA, she starts involuntary 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 voluntary, but only for a limited time.

** Even inanimate objects can "eat" a Zoan Devil Fruit, they gain characteristics of living being and their corresponding animal's intelligence; they also can transform into the animal itself, a hybrid (in the absence of a better word) or their "original" object form.

** Hermione Granger turns into a CatGirl after mixing the wrong hairs in [[CoverIdentityAnomaly a Polyjuice Potion]]. Hilarity Ensures, to Moaning Murtle.

* In 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 and exception; each person has an animal that they feel comfortable with; they can transform into it at any time without having to see a real example. The ability is passed from generation to generation.
* Series/{{Woof}}!, which features a kid who {{involuntary| shapeshifting}} changes into a dog at times.

** ''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. The extinct (unplayable) races are the werebats, wereaurochs, and wereboars.

* In White Wolf's other main RPG, ''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).

** Wizards too, with the right kind of spells. And (like druids) transform other into harmless critters as per the second example of this trope.

* 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.

** ''VideoGame/FireEmblemAwakening'' decides not only to return the Manakete system, but also create the Taguel, a weird hybrid of both Manakete and Laguz mechanics that use magic stones to turn into '''''[[FlatWhat giant magical jackrabbits]]'''''.

** His adopted mother gets transformed into an egg shortly after the game start (the spell went wrong). Later she hatches as an adult duck.

* In the adventure game ''VideoGame/{{Loom}}'', the protagonist's mother along with the guild elders are transformed into swans.
