Shapeshifting Squick



""I swear, once we get through Black Widow, Scarlet Witch, Psylocke, and She-Hulk, I am DONE using her to fulfill my fantasies! And maybe Moondragon, but that's it!""

- Deadpool (see below)

""I've just got one question. If you can change your form into anything you like, why didn't you change it in the one place it counts?""

- Leela on Futurama

One of the first things our sweaty, clammy imaginations suggest to us is that a shapeshifter's sex life must be really interesting. I mean, they can turn into anything right? Ahem...

One of the cleaner subtropes involves a hero seduced by an exploitative shapeshifting minion. This can also apply to metaphorical shapeshifters, such as people with Jekyll and Hyde complexes. It usually suggests an amount of mischief, if not outright wickedness, since it may not be so much a plan to trick the hero as their own little perversion. There are a few ways for the hero to handle this situation:
 * The solicited hero will refuse to be taken in by trickery. (He may get punched in the teeth by the minion but at least his conscience is clean.)
 * The solicited hero comments that the shapeshifter shouldn't have to pose as others to get people to like her. At this point, the (female) shifter goes into her default - but still exotically sexy - form and they have a contented snog anyway.
 * The shapeshifter convinces the hero, but totally wrecks the mood by turning into the wrong thing.

If a shapeshifter is loyally dating, or if the shapeshifter is the hero, this trope is played humorously for that character.

A significant subtrope of Power Perversion Potential. See also Sense Freak, Horny Devils, Shapeshifters Do It for A Change and Showing Off the New Body.

See also Shapeshifting Lover, which has a cleaner history in folklore.

Anime & Manga

 * A mid-series arc in Ranma 1/2 had the eponymous character being bewitched into falling in love with his rival, Ryoga, by a "Fishing Rod of Love." When Ryoga was creeped out by it, Ranma turned into a girl to appease him. It didn't work. But later on, girl-Ranma goes to considerable lengths to get Ryoga to love her back, culminating with a kiss that fuels Ryoga's drive to kill her. After she tries to kill Akane, Ryoga defeats her by accidentally undoing the spell, to his relief. But then when he tries to confess to Akane, he accidentally grabs the wrong person: Ranma, who has returned to her senses. She's Squicked out and pulverizes Ryoga.
 * Bon Clay in One Piece has the power to morph into anyone whose face he's touched before. In a memorable fight between him and Sanji, Bon Clay, exploiting Sanji's chivalry, morphs into Nami, causing Sanji to have a brief dilemma about whether or not to keep fighting him.
 * Okama Queen Emporio Ivankov possesses the power to manipulate hormones within people's bodies, basically changing any aspect about them he wants to. It also works on him should he desire.
 * In Gantz, resident Butt Monkey Inaba Kouki has a crush on the resident hottie Reika. During a routinely brutal mission, he's approached by a battle worn Reika who claims that everyone else is dead and begs Inaba to have sex with her in the middle of a mall foyer (just go with it). Turns out

Comic Books

 * Mystique is pretty much the embodiment of this trope. She is well aware of the implications of her powers and often happily acknowledges them.
 * In the second X-Men movie she seduces Wolverine. He's fairly surprised when she mimics Storm, a little conflicted at Jean Grey's appearance, but profoundly creeped out when he sees her shapeshift into Rogue (essentially a movie version of his traditional underage female sidekick). Turning into Brian "Original Lecter" Cox was just icing on the Do Not Want cake.
 * This scene was parodied in Epic Movie, where a Mystique-esque character is asked to change into increasingly hideous (Fatter! Older!) guises for one character's enjoyment during sex.
 * In an issue of Wolverine, Logan and Mystique apparently sleep together. Logan knew it was Mystique the whole time by her smell, but played along because Mystique was acting WAY out of character and he figured something was seriously bothering her.
 * In a comic book story titled "Bizarre Love Triangle", Mystique takes an exotic female form and attempts to seduce Gambit in order to prove to Rogue (her adopted daughter) that he can't be trusted. When this fails, she takes the form of Rogue.
 * Chris Claremont has gone on record as saying he intended Mystique and Destiny, her (female) lover, to both be Nightcrawler's biological parents. I'll leave you to work that one out for yourself.
 * Another classic Marvel case is Lyja, a Skrull spy who got married to Johnny Storm, the Fantastic Four's Human Torch, in the shape of the Thing's former girlfriend Alicia Masters. The marriage was anulled after the truth came out, but since Lyja actually fell in love with Johnny, she later dated him again in a different human shape as "Laura Green". When she finally wanted to admit the deception he told her already because only one person kissed him like that. Awww. Unfortunately Onslaught intervened, and the two weren't reunited. But in the MC-2 timeline Johnny and Lyja are happily married and have a son called Torus.
 * This is, unsurprisingly, subverted by Deadpool with his shapeshifting girlfriend Copycat (whose power doesn't just let her assume appearances, but memories, personalities and even superpowers). Deadpool recognizes that shapeshifting is driving Copycat crazy, and that he should discourage her from using it... which prompts the opening quote.
 * Hard to say if it goes here, or in Transformation Trauma, in one Silver Age story, Krypto the Superdog accidentally flew through a cloud of Red Kryptonite Dust clouds, and was surprised when he was turned into a pretty Collie. Doesn't sound so bad, or squicky so far, right? Well, he got turned into a pregnant Collie and had given birth to a bunch of superpuppies.
 * An interesting non-comedy example appears in Runaways, with Karolina and her Gender Bender fiancé(e) Xavin. Xavin initially presents herself as male, then promptly transforms into a female when Karolina reveals that she's a lesbian. Thereafter, there's an ongoing thread in the comic about Xavin's transformations; it's never exactly clear what Xavin's "real" sex is, if he/she even has one, and the other Runaways are not entirely comfortable with this. A complication arises when Xavin, knowing that Karolina has feelings for their team-mate Nico, transforms into Nico's shape to please Karolina. It... doesn't really work.
 * Okay, that is just letting Xavin off the hook. S/he knows perfectly well that Karolina has a pile of unrequited feelings for Nico, chooses to morph into Nico and come on to Karoline without mentioning that she is Xavin. It is the meanest kind of fidility-test you can think off.
 * But later, during an unrelated argument, Xavin becomes female without thinking about it--which promptly ends the argument. Karolina's so pleased, she starts talking about that instead.
 * Another Marvel example: Spidey villain Electro was once dating a shapeshifter (or perhaps employing a shapeshifting prostitute) who demonstrated a number of possible forms for that night's... entertainment, including Susan Storm/Richards.
 * ... including Spider-Man...
 * ... If we knew then what we know now...
 * Subverted by a short-lived Defenders character called Cloud who initally had two forms, a small cumulus that could project rain, wind and lightning, and a blatant Fan Service young woman wearing strategically placed scraps of nimbus that always seemed on the point of blowing away. However, once every character with testosterone had got the hots for her, she discovered that she could just as easily coalesce from cloud form into a male body: and did, to general consternation.
 * During Marvel's Secret Invasion plotline, shapeshifting aliens called Skrulls kidnapped and replaced dozens of denizens of Earth - including several superheroes - in preparation for a full-scale invasion. The Skrulls lived as the people they'd replaced for, in some cases, years, meaning that, among others, Hawkeye, Reed Richards, and Medusa slept with Skrulls they thought were their repsective spouses many times. If you piece together the events of three different books, you realize that (1) Hank Pym was seduced by a college girl who slept with him, revealed herself to be a Skrull, captured him, and took his identity, (2) that Skrull, as Hank Pym, then started sleeping with the heroine Tigra, but (3) the process that allowed the Skrulls to pass undetected also caused them to take on the personality of the person they replaced, meaning that the Skrull(s) replacing the brilliant but unstable Hank Pym was actually a series of Skrulls who kept realizing what was going on and needing to be replaced by other Skrulls - all of whom had to maintain the sexual relationship with Tigra AND (4) one of whom got her pregnant.

Fan Fiction

 * The potential inherent in Tonks' sex life is a common thread in Harry Potter fanfiction, both good and bad. In one fic, she describes how she got revenge on a cheating boyfriend by turning into his mother in the middle of sex.
 * Please tell me she then threw the obvious insult at him.
 * Other characters who have plenty of fanfiction invoking this trope include but are certainly not limited to Clayface and Beast Boy.
 * Lampshaded in the DC Nation fan-verse when the characters are taking the 5000 question "internet purity test." Gar's girlfriend (an OC with similar shapeshifting abilities) asks, tongue-in-cheek, "Honey, just how DO we answer those bestiality questions?"
 * And don't forget about the possibilities for Odo/Kira fanfiction...
 * Animorphs fanfic, particularly that dealing with Tobias, his girlfriend, his parents, and other Andalites... I'd say not all at once, but there we have Rule 34.

Film
"Kirk: I can't believe I kissed you!
 * While on a Klingon prison planet in Star Trek VI the Undiscovered Country, Kirk ends up kissing a gorgeous alien played by supermodel Iman. Later in the film he is notably Squicked when he learns that she is a shapeshifter, and that one of her forms is a huge, thuggish, and grotesquely male alien -- and this is on top of their fight scene, where she imitates Kirk. As pointed out in the dialogue:

Not Kirk: Must've been your lifelong ambition."

"Not Kirk: I can't believe I kissed you!
 * Sillier if you switch them around.

Kirk: Must've been your lifelong ambition."

"Kirk: ...is this 'Crater's private heaven'? This thing can become wife, friend, lover... It's not a bad life, having everyone in the universe at your beck and call-- and you win all the arguments!"
 * And in the Original Series, the salt monster who seduced its victims by appearing as their ideal mate, and spends years alone with a man who thinks of it as his "wife"; Kirk even explicitly Lampshade Hangs this trope at one point:


 * The movie Legend has the fairy turning into the heroine to tempt the hero, but he refuses. It almost causes a problem (because the fairy is insulted and almost doesn't help them), and the hero's allies reprimand him for not playing along and kissing her.
 * And we can't forget the scene in Mallrats where Brody asks Stan Lee about the implications of Reed and Sue Richard's relationship...
 * This is lampshaded in Fantastic Four The Movie ("So is it true he extend any part of his body?").
 * Also in one of the comics. "Did I ever mention what a wonderful power that cosmic cloud gave you?"
 * Big is sort of the opposite of Really Seven Hundred Years Old.
 * One of the dream sequences in A Nightmare On Elm Street 3 has one of the cannon fodder being seduced by a sexy nurse, who turns into Freddy from the neck up at a key moment.
 * In The Muppets Wizard Of Oz there's a scene where it's Tin Thing (Gonzo)'s turn to see the wizard. The wizard first appears as this very beautiful green skinned woman... but when Gonzo fails to react to this, she turns into a chicken just like Camilla!
 * As in the standard folklore, in the film Excalibur King Arthur is son of Igraine and Uther Pendragon. He is shapeshifted by Merlin as Igraine's husband (that, at the moment, is painfully dying on the battlefield for extra drama); because Squick was not already hitting the eleven, Uther is in full metal plate armor, with the queen laying under him. Ouch. No time to undress?
 * In 17Again, the main character turns into his 17-year-old self. Problem is, he still loves his wife, who is torn between disgust at the teenage boy for hitting on her and confusion at herself for falling for him (partly because she notices sort of how he looks like her husband's younger self and partly because he knows the various things she likes). This leads to many awkward moments when people walk in on the two in very uncomfortable situations and . On the other hand, she's quite happy to have him back when he turns back into an adult. As if that wasn't bad enough, there's also the squickyness of his teenage daughter trying to hook up with him.
 * Galaxy Quest: the human Fred Kwan falls in love with the Thermian Laliari. Thermians are octopus-like aliens who use advanced holographic technology to appear human. When Fred and Laliari get intimate her control slips and the tentacles come out. Bystanders are thoroughly squicked, but Fred doesn't mind one bit.
 * In Zerophilia (2005), Luke finds out he's got a Rare Genetic Disorder that allows him to change gender at will. This makes for some awkward comedy when he starts to like a girl whose brother starts to like Luke's girl-self.

Folklore

 * This is one of The Oldest In The Book. Foxes in Asian folklore were often given the power to turn into humans and seduce men. Originally, they were often used in stories where a man finds out the one night stand was actually a fox, the horror of that reveal sufficient for An Aesop. However, the additional power of succubus had to be added when the squick factor of accidentally sleeping with an animal, apparently, wasn't enough to get the point across!
 * Not to mention the kitsune myths where the squick works just as well backwards- a useless drunken lout shares his liquor with a cute baby fox, gets it thoroughly inebriated and lets it snuggle up to him like a cat. And wakes up in bed with a drunken, naked teenage boy. Naturally, family members are not amused.
 * Korean foxes don't have this moral ambiguity, though. They're all bad. Man-eating and horrible about it.
 * In many accounts, an incubus can not produce sperm to impregnate women in their sleep, so he gets it from other human men while in the form of a succubus. This explains when a child looks nothing like its father but comes a lot after the neighbors sons. Damn these rapist demons!
 * There's also a Greek myth which says that the gods turned the prophet Tiresias into a woman for seven years. This came in handy later when he could answer Zeus and Hera's debate about whether men or women have more fun. Some versions claim during Tiresias' time as a woman she then spent several years as a famous prostitute.
 * For the record, the answer was something like, "Women, ten times over!", which pissed Hera off enough to strike him blind on the spot. Zeus couldn't reverse the curse of another god, but he could give Tiresias the ability to see the future as compensation. In other versions, it was Zeus who cursed him for proving him wrong and Hera who blessed him.
 * Shapeshifting seems to have been Zeus' standard means of seducing mortals. Hercules' mother, for instance, thought she was sleeping with her husband. That's an example of his most tame sort of shapeshifting seduction. Swans, bulls, golden rains (well, okay, the shower of gold was a metaphor; the woman's father had locked her away to keep her pure, but gold gets you past any locked door -- but still)...
 * An example from the Snorra Edda: as part of a plot Loki shape-shifts into a mare and gets a stallion to run after him... several months later Loki gives birth to an eight-legged horse called Sleipnir, which becomes Odin's mount.
 * Loki was pretty much the master of this trope, being an eternal Trickster with incredibly low sexual restraint (for the Norse gods, at least; he'd be a prude in plenty of other pantheons).
 * Loki was also the father of many strange monsters, including the Fenrir wolf, who is destined to devour Odin, and the Jormungandr dragon, so huge he circles the world with his tail clenched in his teeth, and destined to kill Thor with his poisonous breath. The most disturbing of his children might be Hel, the goddess who rules the dead -- in at least one version of the legend, she was Loki's daughter by the same giantess and witch on whom he fathered Fenrir and Jormungandr. After she was burned at the stake, Loki found her still-living heart in the ashes, which he promptly swallowed. He then ran away into the woods for nine months and gave birth to an adorable baby girl, who was alive on one half of her body and an eternally decaying undead corpse on the other half.
 * In Arthurian legend, the warlord Uther Pendragon falls madly in love lust with Igraine, who is already married to Gorlois. Uther asks Merlin for help, and the wizard transforms Uther into a copy of Gorlois. Igraine makes love to the man she thinks is her husband, and conceives Arthur Pendragon of legend. That's right, the honorable King Arthur is the product of rape by fraud.
 * Meanwhile her husband is killed in the unjust war Uther had begun against him in the attempt to win Igraine, and he marries her a little later. After she's figured out what happened that night. Word of God states they were very happy, but it's pretty full of relationship Squick.
 * And just what does being born of rape have to do with your honor?
 * The Values Dissonance enters the picture where Igraine eventually figures it out and IS OKAY WITH THE RAPE BY FRAUD.
 * Arthur, by the way, commits incest with his sister Morgause (not Morgan Le Fay, btw. The roles only become merged in more contemporary stories). The story varies, in some versions it's an accident and in some it's rape. By either Morgause or ARTHUR himself. The result is Mordred, and as such other things like the ruin of Camelot, civil war, and Arthur's death. So, going by the myths, rape is fine as long as you're not related.
 * A Native American Mythology example is Coyote. One story details how he took a fancy to the wife of a village hunter, so one day when the husband was out hunting he met up with him and turned 'him' into a coyote while Coyote himself took on the husband's form and headed back to the village to sleep with 'his' wife. The young woman didn't even know what had happened until the next day an old (wise?)woman told her that she smelt of Coyote. This toper presumes he returned the husband, thus the woman's confusion. How the old woman knew what Coyote smelt like, however...

Literature

 * In The Unfortunate Miss Fortunes, shapeshifter Dee is still a virgin because she turns into the guy's mother at the crucial moment.
 * In Laurel K. Hamilton's Anita Blake novels, therianthrope-on-human porn movies are all the rage, especially if both start out human and the were-horndog transforms in coitus. In fact, one novel has Anita investigating a snuff version of one such movie.
 * That particular scenario gets inverted in The Shattered World, where Beorn the werebear so fears to lose control of his bestial side that he's never permitted himself to climax with a woman. When he hooks up with Mirrim the werewolf, he hallucinates that both of them are starting to transform and abruptly breaks away from their tryst-in-progress.
 * An early novel by Scott Westerfeld (author of the Uglies Trilogy), Polymorph, centered around a man and his sexual encounters via shapeshifting.
 * It's about a person (originally female) that has an extra organelle that allows her to shapeshift. She's pretty much forgotten her original form and lives off of disability checks (shapeshifting can create convincing-looking disabilities and fake identites). A lot of the squick comes with the antagonist, and how the love interest gets treated in the epilogue...
 * A main character in Octavia Butler's novel Wild Seed is a woman who can shapeshift. She mentions that she can turn into a man and impregnate women. Since the book ends in the mid-1800s, none of the characters understand why all the children she fathers are female.
 * She also turns into a dolphin and mates with other dolphins at one point.
 * Hyperion has one of the most disturbing examples.
 * In one of Marion Zimmer Bradley's Darkover novels, a Terran man falls in love with one of the chieri, the hermaphroditic, elf-like natives of Darkover, in her female phase. In the middle of their lovemaking, she transforms into her male form.
 * Subverted in Harry Potter and The Half Blood Prince. Ron claimed that Fleur is way more beautiful than Tonks, never realising that a shapeshifter can be the most beautiful girl in the world, whatever your taste is.
 * Not as strange, remember that Fleur is one quarter Veela, which is basically a creature with super-pheromones as a superpower. Which Tonks presumably cannot replicate.
 * There was a sci-fi story in which a race of aliens were taught by a human stranded on their planet to transform into humanoid forms (and wage war, which was a foreign concept to them). The shapeshifted beings ended up being attractive by human standards because a human taught them their new form. Years later, a human exploration party arrives. One human guy (a bit of a perv) commands one of the aliens to transform while he's getting it on with her. She's initially hesitant, then very reluctantly obliges... and ends up driving him insane, because her original alien form looks kind of like a huge lobster/bug that directly triggers subconscious human fears.
 * In the Wild Cards novel Busted Flush, Lohengrin is not pleased to learn that his lover Lilith was actually the shapeshifter Double Helix who self-identifies as male.

Live-Action TV
"Trip: You think this is my fault?!
 * First type happened to Tucker and Reed in the Enterprise episode "Two Days and Two Nights". It didn't end well.

Malcolm: You were willing to follow two strange aliens into a basement.

Trip: Gorgeous aliens! Don't forget they were gorgeous.

Malcolm: They were male!

Trip: Not at first!"


 * Honourable mention must be made of the original Green-Skinned Space Babe from the first Star Trek pilot, "The Cage". She was, in reality, a human, but she was able to use the aliens' telepathic abilities to change the way she appeared to Captain Pike. It essentially played out as the first type.
 * The illusion-casting Candice from Heroes tries seducing Sylar by appearing as a geisha, a pair of blond twins and finally Sylar himself.
 * In Season 7 of Buffy the Vampire Slayer, Willow has finally healed emotionally enough from to kiss her new prospective girlfriend, Kennedy. Much to the astonishment of her lesbian partner, Willow promptly turns into a man. Much to Willow's astonishment, it happens to be the man she . Hilarity Ensues.
 * An episode of The Tonight Show With Jay Leno featured a fake advert for something called For Men Only (a parody of men's haircare products) which was a liquid that turns men into women. There are several male to female morphs in it including Jay himself using the product. Another episode had Jay in drag (a supermodel with his voice). And on the episode where Pam Anderson was the guest- Jay asked several questions about implants and then asked her... "If you could be a man, who would it be?" Pam responds "I could be you!" Jay then exclaims "That's perfect. Why?" Pam's answer is "So I could sit there, torturing you, asking about your implants."
 * Star Trek the Next Generation's Wesley Crusher had a run-in with a changeling in "The Dauphin".
 * In "Tapestry," Picard relives the days leading up to when he lost his original heart. Although everyone in his dream/memory/time-travel/thing sees him as a 19-year-old, he is still played by Patrick Stewart, so the audience sees him as a bald 40-something. Approaches this trope when he sleeps with one of his friends, who is of course an actual 19-year-old.
 * Who then turns into Q, much to Picard's chagrin.
 * In Charmed, a recently turned evil again Cole Turner goes to a demonic strip club where he asks a shapeshifter to impersonate his estranged ex-wife Phoebe. The shapeshifter later tried to kill and replace the real Phoebe, worsening the estrangement. At the end of the same episode, he visits the strip club again and asks another shapeshifter to impersonate Phoebe, but this time he kills her.
 * In Deep Space Nine, Odo has a sexual life using this, that is until he starts to MERGE with other changelings, an act which is portrayed as being far more intimate than mere coitus (and much more natural for an amorphous and sexless race). At first he seems to think of it in sexual terms; the writers have fun with this, as when a "male" changeling wants to merge with him in public.
 * By the way, how do we define a gender of a shapeshifter that can take ANY form, male AND female?
 * Shklee?
 * Subverted in one episode when he has sex with a woman, only to find out later that SHE isn't the one who she claimed to be (she was surgically changed into another race and given false memories).
 * In the last episode of the first series of Jekyll, Hyde teases Jackman's (his Jekyll-side's) wife about how he might want to come out when the two were having sex. She responds, 'I might let you'.
 * ...excuse me, I have to go write some Fan Fiction now.
 * Red Dwarf did it in Camille and Psirens.

Tabletop Games

 * There was a Legend of the Five Rings published module where, in the end, it turned out that the "something foully wrong" with a certain monastery was the fact that the head monk was having sex. The problem was, he was having sex with a bog hag in disguise and didn't know it. In that setting, a bog hag is an evil creature that flays living humans alive and can impersonate them by wearing the flayed skin, most emphatically not a shapeshifter.
 * Lunar Exalted have shapeshifting powers that let them switch genders, turn into any sort of animal, or both. This power means that they are able to create Beastmen by committing bestiality as, er, either component, and they can be either mother or father, depending on their whims. Their patron deity has a form that appears as a pregnant human of either sex and it's implied that a sufficiently skilled Lunar Exalted could mimic this trick themself.
 * Somewhat justified in canon; the Lunars were originally created not just as counsellors and stewards to the Solars, but as their mates. When you're an immortal god-king and you live in a setting where a good chunk of the population swings both ways, you're going to need some variety.
 * Changelings in Eberron are probably masters of this trope. Even gender is merely a guideline to them, provided they stay within general humanoid appearance and don't change gender while pregnant.
 * Jokes about the hookers in Sharn pretty much make themselves.

Videogames

 * In Metal Gear Solid 4 the very female Laughing Octopus copies Solid Snake's rugged-older-guy face, just his face.
 * Male Pokémon. Left in the Day-care Center. With a Ditto. The Pokédex entry for Ditto explains that it transforms by copying the other Pokémon's DNA. Think about that one for a second.
 * For extra fun, it can breed with (non-legendary) genderless Pokémon that normally can't breed with themselves. Given that Ditto don't seem to be free-form shapeshifters, maybe there's something different going on here...
 * Ditto...A key to fit any lock...a lock to fit any key.
 * Considering Pokémon have supposedly never actually been seen laying eggs, it's entirely possible that genetics between them are dependent on some sort of stork-type Pokémon...
 * Celebi's pokedex entries from its first appearance in the 2nd Gen onwards mentioned that while it time travels, it sometimes brings back an egg from the future, so until another stork pokemon comes, Celebi is pretty close to the stork-type, for now.
 * In 4th Gen, a well-known breeding trick is to give the mother poke an Everstone, so the offspring has a better chance of inheriting the mother's nature. If something is being bred with a Ditto, the trick only works if the Ditto is the one holding the Everstone and passing on the nature. Conclusion: Ditto is the mother, even if the other poke is female.
 * In the Bhaalspawn Saga, there's a Bhaalspawn Chinchilla. Sure there's humans, elves, dragons, but a Chinchilla?
 * It's more of a surprise that the Realms apparently have chinchillas than that the god of murder of all things doesn't squick as easily as mere mortals.
 * In Dragon Age, Zevran asks Morrigan if she's ever had sex in non-human form. She's squicked by the idea and finds his interest in it unhealthy.

Webcomics
"Nale: "Must... resist... urge to assert...heterosexuality! For the sake... of the plan!"
 * Order of the Stick has a stable romantic relationship between Nale and Sabine, which includes a, shall we say, interesting subversion.

Sabine: "Honey, I am a shapechanger, it's not like we never tried-"

Nale: "Not! Helping!""

"Casey: "If either of us has abnormal sex, I'm sure it's you. Your girlfriend 'has many forms'."
 * Last Resort toys with this one early on, as Alice Quinn transforms into 'fellow prisoner' Daisy Archanis (minus the eyes, of course) in order to convince Jason to pick her as his lieutenant. The squick is more implied than anything else, and thanks to Jason's ambiguous morality, Daisy's more disturbed by the idea than anyone else.
 * In The KA Mics the Ratatosk started the Squirrel Wars because he was egged on by a cute harem squirrel that turned out to be the god Loki. Although, considering that in the Norse myths Loki once took on the form of a mare to draw off a giant's horse & later got pregnant, this behavior was not out of character...
 * In The Perry Bible Fellowship In the comic "Eden", God
 * In The Inexplicable Adventures of Bob, Princess Voluptua revealed to Bob early on that her Hello, Nurse! appearance was an illusion and that she was actually a Starfish Alien. Consequently, they have never pursued a relationship, although his girlfriend Jean still dislikes her hanging around him in all her Green-Skinned Space Babe glory.
 * This in inverted in UC: Deviating from Normality, where a shapeshifting demon tries to find something that will turn Nicodemus on. Instead, he finds something that turns him.
 * Played around with in Something Positive in an early story arc. During a D&D game the resident prick, Mike, complained about newcomer PeeJee throwing off the group dynamic by also playing a female character. The DM, sick of Mike's whiny shit, retconned information about a magic item Mike had picked up in the previous game-- a belt. Mike never took the time to find out what it did; his character immediately put it on and promptly turned male (and now looked like a Player Avatar). The squicktasdedness comes later, when PeeJee used magic, in-universe and adherent to all D&D rules, to create Redneck Trees that proceeded to rape Mike's character.
 * Even worse (almost), was a re-enactment of said rape by some LARPers who got way into the role, and had costumes that would be... er, "fully functional". Mike was just barely saved, and the rescuer immediately regretted the action.
 * He gets better later. ...Much later.
 * This strip in Casey and Andy:

Andy: "It's not like that at all."

Satan: "Oh, honey... I feel feisty. Before bed tonight, I want you to pick your favorite farm animal. You'll find out why later."

Andy (to Casey): "That's probably not good.""


 * In Housepets, we have and his popularity for shipping with all the girl dogs.  is a Baleful Polymorph and.
 * El Goonish Shive: transformations and gender-bending are constants throughout and drive the majority of the plots. Once the characters start hooking up, well...
 * Notably, a noncanonical Remix Comic was a word-for-word redo of the above-linked Casey and Andy strip.
 * In Wapsi Square, Justin once dated a werewolf who liked to change in the middle of sex. Justin wasn't really into it.

Western Animation
"Wildcat: He got in my mouth!"
 * Batman Beyond's Inque. A woman with a sexy voice who's been turned into a living but shapely blob. Creeee-pyyy...
 * Batman the Brave And The Bold had an example with this trope's headliner image character, Metamorpho. Since he can transform into liquids and gasses he can get inside people... don't tell me that's not perverted.


 * The Futurama episode "A Bicyclops Built for Two" has Leela meeting Alkazar, whom she believes to be the other last of her kind. Turns out he was really a shapeshifting cricket who tried to seduce five women to keep his five castles clean.
 * Ben 10 contains are rare inversion in an episode where Ben meets a trio of crime-fightin' aliens. The female Tetramand, a species of massive red-skinned four-armed aliens, is impressed with Ben's Tetramand form and begins flirting with him... until he turns human. Cue disgust.
 * She does, however, later try to encourage him to turn back into Fourarms...Cue Ben's reaction.
 * In the opening of the Young Justice episode "Images", shapeshifter Miss Martian takes on the form of Black Canary to engage in a little Student Teacher Romance roleplaying with Superboy. Canary's boyfriend Green Arrow was amused (after briefly expressing shock that Dinah would cheat on him with a juvenile student). Dinah was not.
