When the MasterOfIllusion or character with VoluntaryShapeshifting wants to seduce someone, they have one very powerful tool in their arsenal: they can be anyone's "type". If they get their amorous advances rejected they will simply change their appearance until they hit paydirt. Common users of this tactic are those with VoluntaryShapeshifting as their main power, [[HotWitch Witches]] (''especially'' if her real form is that of a WickedWitch), {{Enthralling Siren}}s, and HornyDevils (aka Succubi and Incubi).

A little research goes a long way in this regard, and a ''lot'' of subtlety is needed to keep the target from figuring out the seducer is a shapeshifter. ... which is actually fairly rare for this trope, since the shapeshifter will typically be showing off their new forms in a superpower equivalent to a strip tease while the seductee is looking. If the fact that they're being seduced by a shapeshifter doesn't give them ShapeshiftingSquick, they may actually [[PowerPerversionPotential find it really kinky]] and start making suggestions.

One of the quickest ways for this tactic to fail is for the shapeshifter not to do ''any'' research on the seductee or badly botch said research. This can happen if they take the form of a lost love, an ex, or their anti-type, the form likeliest to turn them off and make them run screaming.

If the shapeshifter is impersonating someone whom the target is in love with, it crosses with BedTrick. The trope is also likely to be involved in TheSchlubPubSeductionDeduction.

Subtrope of PowerPerversionPotential. Compare YouSexyBeast, {{Glamour}}. Not to be confused with ShapeshiftingLover, where they only have one alternate form (and it's animal to human). Might be related to ShapeshiftersDoItForAChange, however.



[[folder:Anime & Manga]]
* You can guess how many {{Hentai}} works are based on this concept. ''Cosplay Sex Machine'' is based around this.
* Inverted by the [[LiteralManeater Female Apostle]] in ''Manga/{{Berserk}}'' whom Guts killed at the beginning of the story, she used her ''[[WasOnceAMan original human form]]'' to allure men, the shapeshifting part only comes when she transforms into a creature to consume her food. [[spoiler:We can see her in action during Eclipse arc when Corkus fell into it.]]
* ''Manga/{{Naruto}}'': Naruto Uzumaki uses his Sexy Jutsu to persuade Jiraiya to tutor him.
* ''Manga/{{Gantz}}'' has a particularly {{squick}}y example of this: Koki Inaba ended up having sex with a [[HoYay male alien]] disguised as [[IdolSinger Reika]] [[BuxomIsBetter Shimohira.]]
* Tomoe, a {{Kitsune}} from ''Manga/KamisamaKiss,'' does this for fun and profit.
* In one of the ''VideoGame/TheKingOfFighters'' manhua by Andy Seto, Vice uses her MasterOfIllusion powers to try seducing Kyo under the form of his girlfriend Yuki. [[spoiler: She copies Yuki's appearance but ''not'' her {{tsundere}} personality, [[OutOfCharacterAlert so Kyo soon realizes the trick and unmasks her]].]]
* ''Manga/ToLoveRu Darkness'':
** Nemesis can alter her appearance and reshape her body to look more adult-like (to give Rito a taste of MarshmallowHell) and even change her appearance to look exactly like other people. In a chapter she transform her body into Yui, Mikan and Lala in order to tease Rito.
** Another chapter has Mea take Haruna's form to seduce Rito.

[[folder:Comic Books]]
* [[EldritchAbomination Mary Shelley Lovecraft]] tried this in a ''ComicBook/HackSlash'' story, morphing into a number of Cassie's past love interests while saying WeCanRuleTogether.
* ''ComicBook/{{Runaways}}'': Xavin is in love with [[LipstickLesbian Karolina]], but [[YoureNotMyType he's not her type]]. Fortunately Xavin is a Skrull, with the ability to change his shape - even into a ''female'' shape.
* ''ComicBook/SpiderMan'':
** There was a comic where The Chameleon tried to seduce Mary Jane by turning into different handsome men. [[NoHoldsBarredBeatDown It didn't go over well.]]
** Another comic had Electro visiting a [[PowerPerversionPotential shape-shifting prostitute]], who offered to turn into [[Comicbook/NewWarriors Namorita]], [[Comicbook/FantasticFour Sue Storm]], or the ComicBook/ScarletWitch, among others. Spidey interrupted before we found out who Electro "fancied a crack at" this time...
* ComicBook/{{Mystique}} of Marvel Comics has been known to use her shapeshifting for this purpose on occasion.
** The "Bizarre Love Triangle" arc involves her efforts to seduce Gambit by such a method - first by inventing the false identity of "Foxx" and, when that fails, taking Rogue's form instead - specifically in order to get him to cheat on Rogue and thus prove to Rogue that he isn't good enough for her.
** She transformed into different attractive women for Wolverine years earlier. The first time when she needed protection against Spiral and the second when she needed protection against Sabretooth. In a recent story arc it was revealed that she had in fact started using this tactic against Wolverine nearly a century ago.
* Vanessa Carlyle, Copycat, once transformed into four different types of attractive women who kept bumping into {{Deadpool}}, in order to secure that one of them should be his type. Being Deadpool he ended up having sex with all of them before revealing that he knew it was her all along. After that she kept transforming into different superheroines in bed. Years previously, she transformed into a wide assortment of attractive women to seduce a tycoon, so she could blackmail him to not let his wife know.
* In the nineties, ComicBook/{{Supergirl}}, the Matrix version, who was a shapeshifter, was romantically involved with Lex Luthor. On at least one occasion, when he was obsessing over some plot or scheme, she started shifting into the shapes of various different women (including one who was clearly Princess Leia) to entice him into bed. This is a somewhat unusual example, in that the two were already involved; she was only using her shapeshifting to entice him into bed on that particular occasion, and it was a heroine doing it to (unbeknownst to her) a villain.
* ''ComicBook/BlackMoonChronicles'': [[HornyDevils Succubi]] are able to take on any form, [[ShapeshiftersDoItForAChange female or male]], to lure in victims. Hellaynnea does a very extended demonstration when she offers to serve Wismerhill, going through 30 or so forms, including his previous lover who had been StuffedIntoTheFridge.

[[folder:Fan Works]]
* In ''Fanfic/IfThemsTheRules'' [[OCStandIn Arturus Black]] visits a prostitute [[Franchise/HarryPotter Polyjuiced]] to look like his LustObject, Harry.

[[folder:Films -- Live-Action]]
* ''[[Creator/SeltzerAndFriedberg Epic Movie]]'' has a scene where the Mystique {{Expy}} seduces a character... and he asks her to [[ChubbyChaser get fatter]].
* ''Film/{{Legend|1985}}''. While the protagonists are trapped in Darkness' jail, the fairy Oona tries to get Jack to kiss her by creating an illusion that she's Jack's girlfriend Lily.
* Mystique uses this several times in the ''Film/XMenFilmSeries''.
** ''Film/X2XMenUnited'': She seduces a guard by taking the form of a hot blonde [[spoiler:[[TheSchlubPubSeductionDeduction so she can use him in Magneto's escape from prison.]]]] She later utilizes it on Logan by trying to seduce him in the form of Jean Grey. Logan catches her, and she goes through several other forms, including Storm, Rogue and even Stryker (to taunt him, not to seduce him), but he tells her to leave.
** ''Film/XMenFirstClass'': She upgrades her age by about 15 years to please Erik, which doesn't really work for her until he tells Raven that he prefers her ''[[YouSexyBeast without]]'' the shapeshifted appearance.
** ''Film/XMenDaysOfFuturePast'': Mystique does a sultry variation of her Raven form and pretends to be a disco-loving interpreter to gain access to a Vietnamese general's hotel room in order to steal his invitation to the Paris Peace Accords.
** ''Film/XMenApocalypse'': Her electric purple ensemble is quite revealing, and it's meant to be a distraction to the big, burly guards at the fight club venue; one underestimates her by calling her "little mouse."
* ''Film/{{Excalibur}}''. Merlin using his magic to change Uther Pendragon into the form of the Duke he's fighting in order to sleep with the Duke's wife.
* The female space vampire in ''Film/{{Lifeforce}}'' doesn't change her form again onscreen after she settles on the shape of a beautiful girl, and she has a habit of walking around in the buff. She took this shape directly from the mind of Lt. Carlson, as the image of the girl is his conception of the perfect woman, and uses it to draw him to her and seduce him so she can use his lifeforce in her EvilPlan.
* In ''Film/TheCraft'', Nancy (a Wiccan) goes to get revenge on Chris after he tried to rape her friend Sarah as a result of the love spell they put on him, apparently by seducing him so she can perform a GroinAttack (which he anticipates). When she fails to get in his pants, she morphs her face into Sarah's to tempt him, which works. A double whammy, since the love spell means Chris didn't really love Sarah either.
* In ''Film/ANightmareOnElmStreet3DreamWarriors'', Freddy Krueger uses his dream powers to turn himself into a beautiful nurse working at Westin Hills whom Joey was in love with to lure him away from the group. Things get ugly fast, and he ties Joey to the bed over a fiery chasm before turning back to his burned, dreamstalking self.
* In ''Film/{{Krull}}'', The Beast attempts to seduce Lyssa by taking Colwyn's form, and comments he can take ''any'' form. She is not fooled.
* The movie ''Virtual Girl'' features a [[KissMeImVirtual virtual reality sex program]] [[AIIsACrapshoot gone mad]] that can change into any shape that the user desires. When the protagonist has sex with her, she actually changes form several times in mid-coitus.
* Martia, the Chameloid from ''Film/StarTrekVITheUndiscoveredCountry'', gets in a snog with Captain Kirk when she takes the form of a GreenSkinnedSpaceBabe. She's rather less seductive, however, when she shape-shifts into a giant monster, a young girl, or Kirk himself.
--> '''[=McCoy=]:''' What kind of creature is this? Last night you two were--\\
'''Kirk:''' Don't remind me.

* Gale from ''Literature/SuperPowereds''. Her power lets her see what form someone would find most attractive and shapeshift into it.
* The reluctant, eponymous succubus in Richelle Mead's ''Literature/GeorginaKincaid'' series relies on this power to seduce (mainly) men in order to get the life energy her kind need. Much is made of the fact that the seduction of morally upstanding individuals is made easier by simple groundwork, plus a lot of skill in 'seductive techniques'. Brand-new succubi apparently often lack this carefully-cultivated skill, instead relying on their physical attributes. When Georgina is assigned an apprentice to supervise, she is horrified that the newbie considers 6ft blonde bombshells with breasts that defy physics to be every man's ideal. Said apprentice later reveals that she has much success with college boys, but can't understand why she can't snare moral men. Also, none of the several people Georgina - which isn't her actual name - has romantic entanglements with are attracted through any deliberate act of hers; they fall for her because of who she is. Whenever it is mentioned, none of them ''seem'' interested in the uses the shape-shifting ability might have in the bedroom. This is made more complicated by the fact that Georgina's 'default' form is not her original one either, and hasn't been for about 1500 years.
* In ''Literature/ANightInTheLonesomeOctober'', the Thing In The Circle tries this on the protagonist-narrator in an attempt to get free of the Circle that imprisons it. It never quite succeeds in making him forget what it really is, and all it gets for its trouble is a series of deadpan snarker demurrals.
* Iris in the first ''Literature/{{Xanth}}'' novel does this. She never hid her capacity for [[SuperpowerLottery Magician-level]] illusions (although the more deceptive particulars are another matter), and, this being a ''Literature/{{Xanth}}'' novel, where every able-bodied male is horny as hell, it very nearly works.
* What Saiman attempts with Literature/KateDaniels, but never succeeds. His never-changing eyes make it UncannyValley for her.
* Surprisingly averted in ''Literature/HarryPotterAndTheHalfBloodPrince''. Ron points out that Tonks is nowhere as pretty as Fleur. Hello? Tonks is a shapeshifter, she can be the girl of anyone's dream. Possibly justified as Fleur is part [[TheFairFolk veela]], and has supernatural glamour (which Tonks presumably can't imitate) as well as physical beauty.
** Tonks is the kind of person who would want to be loved for who she ''is'', not for how she can ''look''. Besides, in the wizarding world, beauty is cheap, see polyuice potion. Superficial "love" is also cheap, see love potion.
* In Creator/LarryNiven's short story "The Meddler", the main antagonist, Sinclair, is a crime boss who has a tremendous reputation as a ladies' man, which the hero, private detective Bruce Cheeseborough, confirms after interviewing his exes. It turns out that Sinclair an alien shapeshifter who uses his size-altering abilities in bed. Cheeseborough comments that he "really had gone native" if he found that worth the trouble.

[[folder:Live-Action TV]]
* At the start of Season 2 of ''Series/{{Heroes}}'', the illusionist Candace tries to seduce Sylar with, among other forms, [[TwinThreesomeFantasy hot twins]], and ''[[ScrewYourself himself]]''. He kills her to try to steal the power for himself.
* ''Series/StarTrekTheOriginalSeries'' uses shapeshifting seducers repeatedly.
** In the season 2 episode, "Catspaw," the alien calling herself Sylvia tries to seduce Kirk by showing him several women she can become, saying "Look at me. I am a woman. I am all women!"
** In a variation on the shapeshifting seducer theme, "The Cage" has Christopher Pike taken captive by a race of aliens who want to breed him with their other human specimen, Vina. To seduce him, they show Vina in a series of illusory settings, including one where she is transformed into ''[[TropeNamers the]]'' GreenSkinnedSpaceBabe.
* In ''Series/TheXFiles'' episode "Small Potatoes", Eddie Van Blundht used his shapeshifting abilities to seduce women, generally by posing as their husbands. In one case, he took advantage of a woman crazed about ''Franchise/StarWars'' by appearing to her as Luke Skywalker. [[spoiler:This tripped him up. He knew about her obsession from years ago, and her social circle was pretty small.]]
* ''Series/RedDwarf'':
** Camille in the episode of the same name. She's a GELF (genetically engineered lifeform) who automatically shapes herself to the desires of others. She appears to the mechanoid Kryten as a female mechanoid, to the hologram Rimmer as a shy and awkward hologram, to Lister as a low-dressed vagrant, and to the Cat as... [[{{Narcissist}} himself]]. Her real form is a green blob with stick eyes, which Kryten has no problem with, and goes on a date with her like that.
** The gang also runs into {{Enthralling Siren}}s in the first episode of season 6, who lure space crews to them so they could [[BrainFood snack on their brains]]. When Lister comes face to face with one, it turns itself into a woman Dave lusted after when he was young. He tries to resist, but eventually falls for her charms. Unfortunately these Sirens are of the MasterOfIllusion rather than body shapeshifting type, so we're soon treated to a shot of Lister making out with an 8-foot alien bug.
* Another Siren shows up in the season 4 "Sex and Violence" episode of ''Series/{{Supernatural}}''. It also projected visions of the ideal woman to its victims, while its real shape looked more like a rotting corpse. Strangely, it tries the same thing on Dean [[spoiler:but as a ''man'', as Dean wasn't looking for a bedwarmer but a friend/brother who looked up to him.]]
* In the ''Series/MastersOfHorror'' episode "Dreams in the Witch-House", the witch appears to Walter as his comely neighbor Frances to seduce them. The subterfuge is aided by the fact that he's keeping watch in her apartment at the moment. She eventually turns back into her regular decrepit form and laughs at him as he screams.
* ''Series/LegendOfTheSeeker'': Panis Rahl, who took the form of a young shepherd to seduce the mother of Richard and Jennsen.
* In the ''Series/TheOuterLimits1995'' episode "First Anniversary", the protagonist's wife is actually a foul shapeshifting alien, whose power makes her appear as every man's perfect woman. Unfortunately, the power starts to fade when used too much on someone, such as her husband.
* Attempted in ''Series/{{Charmed}}'' by a demoness with shapeshifting powers who wanted in with [[BadPowersGoodPeople Cole]], who was himself set on a path to becoming the next [[BigBad Source]]. However, Cole [[SingleTargetSexuality is interested solely in Phoebe]]; he didn't give (much of) a damn about the demoness even if she took on Phoebe's form.
* Lyekka of ''Series/{{Lexx}}'' has a natural form of a carnivorous plant monster. However she can take on an attractive human/humanoid appearance in order to lure victims closer so she can feed on them. She ''does'' have a "default" form, however it's the one she specifically used with Stan, and continues to appear in that guise after she falls in love with him.

[[folder:Myths & Religion]]
* In Myth/ClassicalMythology, Zeus is depicted doing this several times when he wants to have an affair with a mortal woman, and often with little apparent regard for what a woman would find attractive. He carried off Europa in the form of a bull and met Danae disguised as a "[[HaveAGayOldTime shower of gold]]." He was in swan form when he chased ''and'' raped Leda (or Nemesis, DependingOnTheWriter). He used the trope's more usual form with Alcmene, though, by taking the shape of her husband so well she was totally fooled. The story that he (initially) hid his true form from Semele presumably includes him taking an attractive mortal human form with her, as well, although unlike Alcmene she wasn't married.
* In one of the Myth/{{Norse myth|ology}}s, Loki talked the gods into letting a Giant rebuild the ruined Wall of Asgard -- and promising him the Sun, the Moon, and Freyja if he finished before the deadline. The idea was to cheat him, except he looked ready to finish on time with the help of his super-strong stallion Svadilfari. The gods demanded that Loki get rid of that horse, so he transformed into a mare and... distracted... Svadilfari. Some months later, Loki gave birth to Sleipnir.
* A fairy tale has an evil witch who changes into the victims feminine ideal and kills them. She learns the hard way that her powers have a limit: A woman disguised as a man slays her.

* Done in all sorts of confusing ways in the ''AudioPlay/BigFinishDoctorWho'' audio "The Maltese Penguin", in which the FilmNoir parody FemmeFatale seems to find Frobisher's penguin form very sexy ([[ShoutOut "You know how to quack, don't you? You just stiffen your beak, and vibrate."]]). She's also attracted to his Doctor form, even though Frobisher notes in his PrivateEyeMonologue that he has trouble kissing people with it because he's more used to having a beak, and that he struggles with humanoid forms because they have 'all those bits hanging off them, which don't even seem to have a use'. [[spoiler: And he's also attracted to ''her'' penguin form. And her default form. And even when she tells him that she had become the pool of blood he'd inspected in an earlier scene, she says it really tickled when he touched it and he seems to find it rather sensual.]] Probably in their case attraction is really just all about the people rather than the bodies.

[[folder:Tabletop Games]]
* Changelings of ''TabletopGame/{{Eberron}}'' are noted to be very popular in prostitution, despite some stigma from fears of an UnsettlingGenderReveal.
* In the games ''TabletopGame/{{Warhammer}}'' and its SciFi cousin ''TabletopGame/Warhammer40000'', the Chaos God(dess) Slaanesh is canonically an androgynous being, which will appear in the form most suited to one's desires. This being Chaos, anything goes from the wholesome to the utterly depraved. Naturally, this fuels a lot of RuleThirtyFour.
* ''TabletopGame/DungeonsAndDragons'':
** The succubi can take any humanoid form to advance their role as TheCorrupter, so this trope is a common occurrence.
** This is also a common occurrence with {{Doppelganger}}s. In fact, since they are sexless in their true form, they are rumored to strictly reproduce when transformed in another race.
** Changelings are descendant of Doppelgangers. Though they have more varied personalities and methods than their ancestors, high-class changeling courtesans/prostitutes are very valued for this reason.

[[folder:Video Games]]
* In ''Franchise/{{Pokemon}}'', Ditto can shapeshift to match any opponent in combat. Once it became possible to breed pokémon, Ditto was revealed to be a viable mate for any fertile partner.
* ''VideoGame/{{Catherine}}'', the titular character [[spoiler: (a succubus)]] takes shape based on a victim's perfect image for a girlfriend.

[[folder:Web Comics]]
* In the (very NSFW) webcomic ''Webcomic/{{Oglaf}}'':
** In "Reward", an [[LiteralGenie overly literal]] shapeshifter performs an all-too-obvious duck behind a tree for a not-very-clever change, having failed to realize the adventurer they're trying to impress was being sarcastic about her interests.
** In "Prince Rodgar", a forest nymph fond of seducing princes to steal their shape [[BecauseImJonesy finds out the hard way]] that her latest victim was lying to keep her interested.
** In "Homecoming", a wife greets her returning husband... only for him to admit in full honesty that he's a shapeshifter disguised as her husband in order to seduce her. Disappointed, she thanks him politely for telling her the truth. [[spoiler:And takes him to bed anyway.]]
* Sabine in ''Webcomic/TheOrderOfTheStick'' is capable of shapeshifting as a succubus, so she doesn't have much of a problem getting people attracted to her so she can have sex with them.
* Yiska of ''Webcomic/CharbyTheVampirate'' changes forms to flirt with [[http://www.charbythevampirate.com/comic/827 Zerlocke]], [[http://www.charbythevampirate.com/comic/829 Victor]] and [[http://www.charbythevampirate.com/comic/910 Daray.]]

[[folder:Western Animation]]
* In one episode of ''WesternAnimation/AlfredJKwak'', [[FunnyAnimal Alfred the anthropomorphous duck]] is pursued by a WickedWitch who [[AndNowYouMustMarryMe wants to marry him]]. Alfred protests, so she transforms herself into a beautiful duck to make it easier for him. Alfred still refuses, since he's engaged to his girlfriend Winnie.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'''s changelings, who are essentially G-rated [[HornyDevils succubi]], impersonate other sentient creatures and [[EmotionEater feed off of the love]] of those close to them. Presumably, this trope is how they go about it when they're not amassing in force to invade entire nations, as was witnessed in the case of [[spoiler: [[GodSaveUsFromTheQueen Queen]] [[VileVillainSaccharineShow Chrysalis]] impersonating Princess Cadance in order to leech off of Shining Armor]].
* The bartender in the ''WesternAnimation/AmericanDad'' episode "Lost in Space" can change her appearance to make herself attractive to anyone. Since she works on a space station with dozens of different alien species, she changes quite a bit. She apparently only does it because she's just really, really horny.
