Being able to transform part of, if not your entire body, seems like it would be a bonus. However, someone with body issues or incapable of dealing with these new powers might have Transformation Trauma, or at least have unforeseen issues they didn't have before having the ability to change their form.

Other Examples
Comic Books
- X-Men: Part of Rogue's powers of power-stealing involves changing her appearance if the power has a specific physical component to it. Since Rogue already has issues arising from not being able to be touched, early in her career she didn't want to tarnish her beauty by risking looking like Colossus or Nightcrawler if she took their powers.
Fan Fiction
- The Land of What Might-Have-Been: The Amorphous League are a group of hobbyist shapeshifters who took up their powers in order to escape the stress of living in Unbridled Radiance... only to be hit by numerous iterations of this trope. First, becoming shapeshifters made them criminals under the Radiant Laws for "crimes against beauty." Second, the potion that gives them their powers runs the risk of reducing the drinkers to paralyzed goo if they overdose. Thirdly, it takes a lot of time to improve their abilities. Fourth, continuous use of the potion gradually erodes features, sexual characteristics, and even physical identity.note
Films — Animation
- NIMONA (2023): The title character is a powerful shapeshifter capable of assuming almost any form... but is unable to connect with anyone as a result. Animals instinctively reject her, humans accuse her of being a monster, and even Ballister spends most of their early interactions asking her to be "normal" — not realizing that Nimona's shapeshifting is an integral part of her being and that not transforming is unbearable for her. In the finale, all these rejections and more drive Nimona to a suicide attempt — though Ballister thankfully saves her at the last moment.
Films — Live-Action
- X-Men (Film Series): After living a life shapeshifting to blend in and survive, Mystique became deeply insecure that she is unlovable in her true (blue) form. After joining Magneto, she does a 180 and now resents being forced to change her appearance to win the world's acceptance.
Literature
- Harry Potter:
- People use Polyjuice Potion in many of the books, to transform into somebody else. This is introduced in Harry Potter and the Chamber of Secrets, in which they learn how painful the transformation can be, and Hermione accidentally transforms herself into half a cat, when she mistakenly uses a cat hair as an ingredient.
- Related to this is that Apparating (disappearing and reappearing somewhere else) is extremely difficult, and if not done correctly, can result in Splinching: leaving part of one's body behind.
- A metamorphmagus is a variety of witch or wizard with the innate ability to change their appearance to anything human. Nymphadora Tonks uses this talent for infiltration purposes, and struggles to keep her balance because constantly changing her height and weight that way throws off her center of gravity.
- Merman's Kiss: Merpeople in the setting of this book series can take on human form but there are a lot of complications that come with it. First, the transformation is very painful and often causes the person to black out. Second, merpeople can only stay in human form for a limited amount of time before being forced back into their true form, meaning they have to be in seawater at least twice a day. Thirdly any injuries in merpeople form carry over into human form as one of the characters Zarya finds out during Daughter of the Sea when she goes on land and finds out to her dismay that her ripped-off fin means her human form has no foot on one leg.
- Patternist: Anyanwu is blessed with unprecedented power over her cells, allowing her to shapeshift into any living being or animal, not to mention make herself virtually immortal; she can even change sex at will... but regardless of whether she acts as the father or the mother, none of her children have ever inherited her powers, meaning that she's been condemned to watch them die of old age over the centuries. When Doro finds her, she's initially fascinated by the company of a fellow immortal... but his ruthlessness and Lack of Empathy gradually repel her, and the fact that her shapeshifting powers make her a key part of his Super Breeding Program leave Anyanwu even more miserable than ever before - to the point that she serious considers suicide as her only means of escaping him.
- Red Dwarf: Symbi-Morphs have the ability to turn themselves into just about anything... but have been bred to use their abilities to sexually service their creators, and even after their masters aboard the Colony Ship were overthrown, their fellow genetically engineered life-forms continue to exploit them in a similar fashion. Symbi-Morphs are the only inhabitants of the GELF State that lack even the most basic rights, can find no work except as sex slaves, have to be "broken" before they can service clients, are beaten if they become too attached to one of their clients (which they were designed to do), and are threatened with spaying as punishment for resistance. For good measure, they're conditioned to only find Happiness in Slavery — to the point that an "unbroken" specimen by the name of Reketrebn doesn't even consider using their shapeshifting powers to escape until they are bonded with Lister.
- Reign of the Seven Spellblades: In volume 2, Pete Reston has a strange dream and wakes up to discover his body has become female below the neck. He spends most of the following day irritably snapping at his friends because he has no idea how to deal with this (and because the transformation is causing painful side effects because his body isn't used to it) before Oliver and upperclassman Carlos Whitrow figure out what happened. Oliver explains to Pete that he's a "reversi", i.e. a Sex Shifter, and Carlos invites Pete to join a (heavily queer-coded) campus club for students with gender- and sex-linked magical traits, with Oliver tagging along to keep Pete company.
- Star Wars Legends:
- Clawdites have the power to disguise themselves as other humanoid beings... but unfortunately, the genetic mutations that led them to develop these abilities have made them a Fantastic Underclass on their home planet, segregated to slums and restricted from any kind of formal education. To add insult to injury, their shapeshifting powers can be quite painful to use for younger Clawdites, and even experienced members of the species require regular doses of moisturizing oils to prevent their skin from cracking under the strain.
- The Shi'ido have it a lot better than the Clawdites, with longer lifespans and more impressive powers... but they still suffer from numerous drawbacks: because their powers were developed to hide themselves from predators, Shi'ido are extremely shy, to the point that even those who live public lives off-world are known for being cautious and withdrawn... and as Galaxy of Fear demonstrates, this can lead to their non-Shi'ido friends and relatives believing them to be uncaring, even if the shapeshifter genuinely loves them and the fact that Uncle Hoole is also struggling with the baggage of his Dark and Troubled Past doesn't help. Also, their powers and compulsive need to observe others have given them a nasty reputation as spies-for-hire, though Senior Anthropologist Hoole is doing his best to combat this stereotype.
- Witherward: The Changelings have the power to transform into almost anything but are subject to more discrimination and exploitation than any other supernatural race in Witherward, with reactionary groups regarding them as a Fantastic Underclass at best and animals at worst - to the point that when one Sorcerer forced a Changeling couple into debt slavery, he went out of his way to use a Power Nullifier on them so that they'd be trapped in the form of horses until their minds eroded into animal instinct after months of drudgery. And things don't get much better when they leave Witherward for the normal world: Ilsa was accused of being a devil by her human caretaker and subjected to all kinds of abuse throughout her childhood - to the point that by the start of the story, Ilsa suffers from chronic claustrophobia, is consumed with the fear of being a devil after all, and is so badly scarred that only her shapeshifting powers can hide it.
Live-Action TV
- Star Trek: Deep Space Nine: The titular station's chief of security Odo is an alien made of goo that can imitate just about any object or life-form. However, he is young and inexperienced and has trouble getting the details of his forms down. The form he primarily takes on, that of his adoptive Bajoran father Dr. Mora Pol, isn't very convincing and has a misshapen, mannequin-like face.
- The Twilight Zone (1959): "The Four of Us are Dying" features a man who can imitate any form he sees, if he concentrates hard enough. Unfortunately for him, one of the identities he assumes is that of a man who so badly wronged his family that the father of the impersonated man shoots him dead in retribution.
Tabletop Games
- GURPS: In the gamebook Shapeshifters, the Hider doppelgangers are shapeshifters who can impersonate just about anyone but suffer from compulsive shyness, mild-to-extreme paranoia, and an overwhelming dread of something hunting them down. As a result, they can spend entire lifetimes in disguise, usually playing the part of housewives and other traditionally submissive roles so they can both avoid attention and remain financially secure; unlike their Hunter counterparts, they have no "fight" reflex, and when confronted with danger, their first instinct is to run and hide - often into a different identity entirely.
Video Games
- Genshin Impact: Kirara has relatively few problems now being a Nekomata, but she notes that now having two tails makes it difficult to sleep. She also has to deal with the fact that things she gets away with doing as a cat are different from what she can socially do as a human.
Web Animation
- Strong Bad Email: Discussed and parodied in "shapeshifter", where Strong Bad goes into depth on how shape-shifting wouldn't be a good idea as it always needs some kind of drawback and shows some comical examples. Highlights include the ability to change into any balloon animal or the ability to turn into "almost anyone" meaning that he shapeshifts into part of a person.

- SCP Foundation:
- SCP-2750
designates a race of Native American shapeshifters believed to be responsible for the belief in Skinwalkers, capable of transforming into at least five different animals common to the American Southwest. Unfortunately, their powers made them widely feared and persecuted by humans, ultimately leading to the Foundation's predecessors conducting a war of extermination that nearly ended with the entire species being wiped out. Modernization also killed off much of the wild game they preyed upon, and by the 21st century, the 2750 population has dropped so low that many are forced to resort to inbreeding, damaging their shapeshifting powers and often leaving instances trapped between forms. As such, they are now a Dying Race.
- SCP-7955
is a shapeshifter capable of becoming almost anyone or anything, but at the cost of suffering progressive dementia as his powers grow stronger. As such, most of the documentation features him slowly losing his memories, his intelligence, his personality, and the ability to hold a single form for more than a second, until he's reduced to an Empty Shell. Subverted in the finale, where he regains enough lucidity to explain that he doesn't regret his powers or the side-effects, having acquired both with full knowledge of the cost, ultimately dying happy.

Web Videos
- Pop Cross Studios: Redemption of the Were-Jaguar
deconstructs this trope with the titular were-jaguar, Vasilia Kuznet. Despite projecting an image of herself as a "tall, confident and gorgeous" woman (which, for the most part, she is), she secretly harbours deep shame at having been bitten and turned by another were-jaguar that she killed at the age of five. Early on, she used to transform uncontrollably and attack her family and neighbours, so an ashamed Vasilia tries hiding it from her friends, and especially her boyfriend Heath. So, upon arriving in another dimension which leaves Vasilia in a Shapeshifter Mode Lock, she panics and tries desperately to find a way to get them all home without giving her secret away. On top of that stress, Vasilia has to work alongside the Van Helsing family, whose ward, Gangadharan, treats her with unwarranted suspicion, which makes her angry enough to feel tempted to lose control and lash out. But as Gangadharan points out, her past woes don't justify her secretive behaviour:
Gangadharan: You claim I have trust issues, and yet, if you truly have control over this form and all its power, why would you not be constantly turning into it?
Vasilia: Because I get enough judgment from family for it after years of not having control! Friends need not know about werejaguar form, even if I do have control now!
Gangadharan: Only further emphasizing my point! Either you don't have as much control as you claim, and avoid turning to conceal that fact, or you do have full control, as you say, and don't trust your friends to be accepting of your... more fanged side. So, don't lecture me about trust, because you're either a liar... Or a hypocrite.
Western Animation
- Ben 10 revolves around a kid with an alien Transformation Trinket permanently attached to his wrist, so it should be no surprise that Ben's had just about every problem that a shapeshifter can run into. Quite often, the Omnitrix transforms Ben into the wrong alien, gives him new forms he initially has trouble moving around him, and will time out and revert him back to human in the middle of a battle. Sometimes the Omnitrix itself is as big a problem as whatever the current Villain of the Week is.
