In any case, the character is generally aware they have this ability, and it's a recurring aspect of their character; the shapeshifter will generally try to avoid triggering their ability accidentally (e.g. [[Comics/TheIncredibleHulk Bruce Banner]] constantly warning people YouWouldntLikeMeWhenImAngry); alternately, they can expose themselves to the trigger to deliberately invoke their ability when it's convenient (e.g. stimulus + container to hide it = instant TransformationTrinket); the line between voluntary and involuntary can get a little blurry, but unlike the Voluntary Shapeshifter, the involuntary one lives with a risk of transforming [[FinaglesLaw at the most inconvenient moments]] should their trigger hit them unexpectedly. (Even if they don't end up transforming very often, the potential for it is still there.)

* You can become one temporarily in ''VideoGame/NetHack'', by wearing a ring of polymorph, or permanently by ''eating'' it. Combining it with a ring of polymorph ''control'' does exactly what it sounds like, making you a VoluntaryShapeshifter instead.

* In Creator/TerryPratchett's Literature/{{Discworld}} series, Nanny Ogg's cat, Greebo, is temporarily turned human. Afterwards, his morphic field remembers the shape and shifts back to it when under stress, much to Greebo's consternation. Also, in ''Discworld/TheLastContinent'', the Librarian catches the flu and, again, because of a weakened morphic field, changes shape every time he sneezes. Werewolves ''have'' to transform in the light of the full moon, but beyond that they can change whenever they like. There's a variant in a wolf who transforms into a ''human'' at the full moon.

* On ''Manga/TokyoMewMew'', Ichigo's cat ears and tail pop out whenever she's frightened or excited. This occurs most often in the presence of her love interest, but also inadvertently led to the discovery of the fourth Mew Mew.
** This later intensifies as she [[{{Animorphism}} becomes an actual kitten]].
* In the ''Anime/RevolutionaryGirlUtena'' movie, Utena and Shiori turn into cars, for reasons that only make sense if you read the plot as an [[MindScrew allegory]].
** Nanami also turns into a cow (or at least [[MindScrew thinks she does]]) in both the regular series and the movie.

** Tutu's own transformation might be considered involuntary, too, as the behind-the-scenes author that "writes fate" at the beginning of the story calls her into being by speaking her name; however, she always agrees to it. What Ahiru ''doesn't'' agree to, though, is turning into a duck when she gets excited and having to cart her clothes to the nearest water source.

* ''Manga/DragonBall'' character Lunch (Launch in the American dub) changed personalities (and hairstyles) whenever she sneezed.
** The Oozaru, or "great ape" transformation on the full moon is essentially this for all Saiyans. The only way to stop an Oozaru rampage is to chop off the Saiyan's tail or blow up the moon. For Goku and Gohan, it's very much a curse, though other, more bloodthirsty Saiyans (such as pre-Namek Vegeta) use the transformation to their full advantage. This of course has something to do with the fact that they are apparently able to keep their minds while transformed and direct the brute power. Goku became fully animalistic while transformed with no memory of his actions in Oozaru form afterwards, [[spoiler: making him unaware that it was he who killed his grandfather.]]

* In European folklore, werewolves are not in control of their shapeshifting; it being an artifact of phases of the moon and/or the presence of certain plants (such as "Wolfsbane", aka ''Aconitum'' spp.). Well, there are two kinds of werewolves in European mythology - the merely cursed and the truly evil. The former indeed usually change under certain conditions (like the aforementioned full moon), while the latter ''deliberately'' turn themselves with evil witchcraft, which typically involves wearing fur of a wolf on their back.

Those cursed are not in control of their shapeshifting; it being an artifact of phases of the moon and/or the presence of certain plants (such as "Wolfsbane", aka ''Aconitum'' spp.). Well, there are two kinds of werewolves in European mythology - the merely cursed and the truly evil. The former indeed usually change under certain conditions (like the aforementioned full moon), while the latter ''deliberately'' turn themselves with evil witchcraft, which typically involves wearing fur of a wolf on their back.



* In Dungeons and Dragons, afflicted lycanthropes (those who were bitten, rather than having been born with the condition) do not have perfect control over their shapeshifting, and may involuntarily assume their alternate forms in response to damage or the full moon.

* ''TabletopGame/MagicTheGathering'' Changelings are every creature type at once. This includes anything from squirrels, whales, to Gods. That being said, they are affected by anything targeting a specific kind of creature, be it beneficial or downright fatal.
** A typical [[HordeOfAlienLocusts Sliver]] does not itself possess the ability to shapeshift (Except if that *is* its ability). Their shifty-ness comes from the fact that they tend to share their inherent abilities with other Slivers. If said ability is having, say, an extra arm, a pair of wings, or even a second freakin' HEAD, that ability is passed to any Slivers nearby, be they allies, neutral, or hostile. The shared ability is also lost when the source Sliver either leaves the area or dies. In a single battle one may encounter Slivers spontaneously sprouting and losing all manner of appendages and protrusions. This power is (was) completely beyond their control. Que a bit of FridgeHorror for them when one considers how bad growing pains can be; imagine having an extra limb suddenly pop out from your chest within seconds, complete with the sound of snapping tendons and straining muscle.

* Certain {{Pokemon}} in the videogames have the ability to change between various physical forms. The third-generation Pokémon "Castform", for example, changes its shape (and elemental type) depending on the current weather. (Castform also has the ability to control the weather). Giratina can only assume its serpentine Origin Form with the help of the Griseous Orb, and Shaymin can only transform into its Sky Form with a Gracidea flower in its possession.
* In ''Prince of Persia: The Two Thrones'', the Prince acquires a "Dark Self" that takes over his body during times of extreme danger (though the player is still in control of the Prince), and can only change back if he touches water.
* ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' and ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'' both have diseases that can turn your character into a vampire (or, in a ''Morrowind'' expansion, a werewolf.) After this happens, your character will constantly have to battle their own involuntary shapeshifting by drinking blood -- you normally look human, but spend long enough without feeding and ''everyone'' will recognize what you really are. Falls into the first variety for werewolves, and both the first and second for vampires if ''Oblivion'' is to be believed.
* In the ''JakAndDaxter'' series (all games but the first), Jak is infected with a substance called Dark Eco and transforms into a hulking, monstrous version of himself when [[HulkingOut sufficiently angry]] or distressed. He eventually learns to control it to some degree. The same thing happens to [[spoiler:Daxter]] during ''Lost Frontier''.
* Baldur's Gate 2 contains many examples of shapeshifting, mostly voluntary (class abilities) or offensive (Polymorph Other, aka Baleful Polymorph), but there are several involuntary ones as well. The best example is the Slayer transformation, which can be triggered voluntarily but also happens involuntarily after certain events or dreams. Another example is the description of the Shapeshifter class, which specifies that the Shapeshifter has voluntarily inflicted themselves with the sort of lycanthropy that causes involuntarily shapeshifting into a Werewolf, but then studied for many years to learn to control said transformations to make them voluntary, at the cost of failing to learn any other shapeshifted form.

* Kieri, an angel in ''Webcomic/SlightlyDamned'', was cursed by a guardian and turned into a snow bunny (subsequently nicknamed "Snowy").

* In ''WesternAnimation/AlienatorsEvolutionContinues'', as a result of him volunteering as a human guinea pig for finding a cure against the Genus, Wayne Grey undergoes random mutations (including growing extra limbs, splitting into more copies of himself, or becoming animal-like in appearance) every time there is a high concentration of alien cells in the surroundings.
** In one particular episode where the aliens grow out of control and briefly take over the whole world, he kicks into overdrive and explodes into a pink goo.
** In the final episode, the whole team gets sent on the Moon. Makes you wonder what the hell a ''two-headed spacesuit'' was doing in a space shuttle.
* Various ''{{Transformers}}'' have had occasions where they lose control of their transformations between robot and alternate modes. Most commonly, this happens when they're hit hard enough, or as a reflex when one is startled. ''WesternAnimation/BeastWars'' was rather fond of the former.
* ''AmericanDragonJakeLong'', Jake began to shift randomly from human to dragon, sometimes [[PartialShapeshifting one body part at a time]], in one episode. Application of "liquid plot" did this once, revealing his identity to his worst ''human'' enemy.
* Early in ''WesternAnimation/DannyPhantom'', Danny has trouble controlling his powers and would sometimes go partially ghost at random. Led to his pants falling down at one point, memorable for a line that followed later that episode. The beginning of the episode "Identity Crisis" ''really'' emphasized this with Danny's shape shifting abilities. Very amusing.
* In the ''WesternAnimation/TeenTitans'' episode "Haunted", Beast Boy (who is normally a VoluntaryShapeshifter) has had occasional mishaps, such as a series of transformations that occurred during a sneezing fit from the common cold.

* ''WesternAnimation/{{Beetlejuice}}'', from both cartoon series of the same name, changed constantly based on any wordplay to be found in his dialogue, apparently by force of habit. In one episode, some of the bad guys he'd faced exploited this by tricking him into saying "I'm coming apart at the seams", and then scattering his body parts when he literally fell apart.
* Similarly, ''WesternAnimation/{{Bonkers}}'' in one episode caught "literalitis", a disease which caused him to take the form of any idiom he heard.
** In another episode his first partner, Detective Lucky Piquel, caught "toon flu" and turned into this little three-inch high character when he sneezed.
* The main character of ''TurboTeen'' would shapeshift into a ''talking car'' when his body temperature rose, always at inopportune times.
* WesternAnimation/DarkwingDuck gets zapped with an experimental TransformationRay in one episode, and gains the power to turn into anyone he looks at. Downside is, [[PowerIncontinence he can't turn it off]].
** And this was only one of many episodes of ''Darkwing Duck'' with this trope as the premise.
** A ''DonaldDuck'' comic story by Carl Barks once used a variation where Magica De Spell comes up with a concoction that, after having been sprayed onto somebody's face, would change the victim's face to that of anyone they look at. She naturally plans to use it to blackmail Scrooge to get his dime.
* In the episode "Dexter's Date," ''{{Freakazoid}}'' is zapped at a television station and cannot change back into Dexter Douglas, leaving his date waiting - and turning instead into random celebrities.

* In ''ProjectGeeker'', Geeker is a genetic shape-shifter who [[PowerIncontinence can't control his abilities]]; he sometimes collapses into a puddle when he panics; in one episode, he sleep-walked through the city for several nights -- in {{Kaiju}} form.
* Dingo of ''SonicUnderground'' had the ability of transforming into virtually any other object or person, though these were invariably orange in color. His transformations were completely under control...of his partner Sleet, that is, not himself.
* WordOfGod has it that, in the ''{{Transformers}}'' metaseries, Primus, Unicron, and the Original 13 Transformers's bodies automatically change to fit the physics of whatever universal stream they enter (similar in effect to a FisherKingdom, but caused by themselves, not the universe they enter). Primus and Unicron stopped there, but the other 13 changed further to fit the specific idiosyncrasies of the local Transformers. For example, when The Fallen was in the G1 universe, he looked blocky, and in the live action movie universe he looks more thin, lithe, and pointy. Also, in G1 he was [[IncendiaryExponent on fire]], while in the movie universe, due to physics, he was merely glowing red-hot.
* ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'': During the last two seasons of the first cartoon, this began happening to the turtles themselves: at inopportune moments, they would transform into monstrous, mindless forms. At the same time, the turtles had made a new ally in Carter, who also suffered from his own kind of involuntary shapeshifting, albeit one in which he kept control of his faculties.
* An episode of ''WesternAnimation/TheFairlyOddparents'' had Cosmo shapeshifting against his will due to his "Fegiggly Gland" working wrong.
* Chuck Jones' bizarre late-entry ''WesternAnimation/LooneyTunes'' "I was a Teenage Thumb" had a wizard with the hiccups who would transform into different random things with each 'hic' - a lamppost, a touring car, a hot-air balloon...
* {{Kaeloo}}'s Mr. Cat is one of these, his transformations into random objects usually brought upon by Kaeloo beating the stuffing out of him.
* On ''AttackOfTheKillerTomatoes,'' Tara Boomdeay gets turned into a tomato when she touches salt. She turns back into a human girl after having pepper sprinkled on her and she sneezes.
* In the Al Brodax {{Popeye}} cartoon "The Wiffle Bird's Revenge," the Wiffle Bird casts a spell on Wimpy, making him turn into a werewolf when he says the word "hamburger."
* In WesternAnimation/AladdinTheSeries, Genie comes down with a case of PowerIncontinence where his sneezes cause random magical effects to anything nearby, covering his nose when he sneezes instead caused him to transform randomly (and uncomfortably).
