->"''no homo''" says the boy cuddling next to you. You figure he means he isn't homosexual. It never grazed your mind he may be stating he isn’t a homosapien [''sic'']. That was a very big mistake on your part.
-->-- '''squided''', Website/{{Tumblr}}

A boy meets a [[MagicalGirlfriend girl of his dreams]], falls in love with her, is reciprocated, and all seems shiny... until TheReveal that the girl isn't quite compatible with him biologically. For example, she is an [[HumanAlien alien]]. Or a [[CuteGhostGirl ghost]]. Or a [[OurDemonsAreDifferent demon]]. Or a [[BigCreepyCrawlies six-foot praying mantis in a person-suit]]. Or... Either way, she is not human and that's a slight hindrance in their relationship. How exactly it plays out depends largely on the author:

* ThePowerOfLove rules supreme and InterspeciesRomance ensues;
* They are forced to [[StarcrossedLovers part ways despite still loving each other]];
* She offers him to [[ViralTransformation make him just like her]] and he agrees (very common for vampires);
** Occasionally, this is done to save his life via an EmergencyTransformation; the relationship [[ILoveYouVampireSon may]] or [[IHateYouVampireDad may not]] survive this act.
** Alternately, he manages to purify her, assuming her condition is reversible and [[CursedWithAwesome seen as bad]]. A CuteGhostGirl might find [[AnAstralProjectionNotAGhost her body in coma state in hospital]]. God may "punish" an angel by turning her into mundane human.
* One of them just [[LoveCannotOvercome can't get over it]] and breaks up.
* [[LiteralManeater She eats him.]]

{{Gender Flip}}ped (completely or [[YuriGenre par]][[YaoiGenre tly]]) variations are also included.

If they stay together, {{Half Human Hybrid}}s may result.

Subtrope of InterspeciesRomance. May be a case of MagicalGirlfriend or even ActionGirlfriend. A common trope in ParanormalRomance but it appears in other genres as well. See also BoyMeetsGhoul.

!!As this is a form of TheReveal, [[Administrivia/SpoilersOff unmarked spoilers abound]]. [[Administrivia/YouHaveBeenWarned Beware]].

%%* ''Literature/{{Baccano}}'': Boy meets [[OurHomunculiAreDifferent immortal, borderline asexual homunculus]].
%%* ''Anime/BlueSubmarineNo6'': Man meets mermaid/catgirl hybrid with similarly ambiguous bittersweet ending.
%%* ''Literature/CatPlanetCuties'': Boy meets CatGirl Alien, knows a [[HalfHumanHybrid Half-Alien]].
%%* ''Literature/TheDevilIsAPartTimer'': Girl develops crush on [[BlandNameProduct MgRonald's]] coworker. Girl goes out with coworker. Coworker's [[SheIsNotMyGirlfriend alleged ex-girlfriend]] interrupts date and warns girl to stay away from coworker, as he is {{Satan}} incarnate. Girl discovers that alleged ex (really a [[HalfHumanHybrid half-angel hero]]) was being literal.
%%* ''Anime/DragonautTheResonance'': Boy meets giant, alien dragon.
* Retroactive example: ''Anime/DragonballZ'': Chichi learns her husband Goku is an alien. He didn't know either until his brother showed up. Although he was pretty obviously not a ''human'' from the beginning, as he had a tail and turned into a giant ape under the light of the full moon. We just didn't know he was an ''alien.''
%%* ''Literature/DragonCrisis'': Boy meets Dragons and a [[HalfHumanHybrid Half-wolf girl]].
%%* ''Manga/DreamEaterMerry'': Boy meets Dream Demon.
* ''Manga/DuskMaidenOfAmnesia'': Teiichi doesn't realize Yuuko is a ghost when he first meets her, but she's quick to point it out, and has him convinced before long. It doesn't stop him from falling for her when they start spending time together in the newly-formed Paranormal Investigations Club.
* ''Anime/EurekaSeven'': [[spoiler:Eureka is actually a HumanAlien. Renton finds out late in the series, by which point he doesn't care, even after she starts [[FreakinessShame changing.]]]]

But she was only dating him in hopes of [[spoiler:getting intel on Mustang's movements, and is perfectly willing to kill him (and everyone else involved) once he finds out]], so the relationship would have broken up anyway.
%%* ''Manga/MermaidMelodyPichiPichiPitch'' has an inversion (mermaid meets boy), [[spoiler:which is later subverted as the boy isn't entirely human either; they are allowed to remain together.]] The other members of the PowerTrio, also mermaids, get human love interests as well; the manga makes it more clear that they'll probably end up StarcrossedLovers because of this, but the anime ends on a happier note. Finally, the series' backstory includes other stories of boy-meets-mermaid played straight; one is a legend with an ambiguous ending, but the other... [[StarcrossedLovers didn't end well]].
%%* ''Manga/NegimaMagisterNegiMagi'': Boy meets [[UnwantedHarem all]] [[FantasyKitchenSink of the above]].
* ''Anime/SpacePirateMito'' relates the story of her own reveal to her beloved Kagero to her HalfHumanHybrid son Aoi and asserts that he is the living embodiment of ThePowerOfLove because Kagero married her anyway.

[[folder:Fan Works]]
%%* Novembersmith's RPS fan-novel ''Fanfic/TheAnatomyOfAFall'' has boy meets ghost, with a fairly beautiful [[TheReveal reveal]] around the middle of the fic.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fic ''Fanfic/FluttershyIsFree'', this is what happens to [[spoiler:Fluttershy's mother]], when she wakes up just a bit too soon and discovers she's lain with [[spoiler:a Changeling]].
* Downplayed in ''Fanfic/TheGirlFromWhirlpool'' in regards to [[SealedInAPersonShapedCan Kushina]]. It ended up costing her her first boyfriend, but Minato took it far better (despite nearly being killed as a direct result of the reveal).
* In ''Fanfic/OriginStory'', Louise originally thinks that Alex is a mutant, just like Louise. When Louise finds out that Alex is actually from another dimension, she freaks out, but gets over it. By the time that Louise finds out that Alex is not only from another dimension, but is from an alien planet in another dimension, Louise is so far beyond shockable that she almost yawns at the news.
* GenderFlipped in ''Fanfic/RedLightning'' when Double-D is forced to reveal he's a [[DifferentlyPoweredIndividual Super-Psycho]] to Marie after Conner accidentally outs him.
* GenderFlipped in ''Shadows Of The Past'' as [[spoiler:Will mentions how he showed Sarah what he really was]] when they were dating.
* GenderFlipped in ''Fanfic/SonOfTheDesert'' Hohenheim tells Trisha of his true nature [[spoiler:as an immortal]] the night before they get married. Trisha takes it rather well after her shock over his [[ReallySevenHundredYearsOld actual age]].
* Downplayed in ''Fanfic/SonOfTheSannin''. Shino doesn't find out about Fu being [[SealedInAPersonShapedCan the jinchuriki for the Seven-tailed beast]] until the day before they start dating, though since Naruto's status as a jinchuriki was never made a secret in this story, [[FantasticallyIndifferent his only reaction is that it's "interesting"]].
* In ''Fanfic/WithoutAHive'', "Meadow Song" is outed during the changeling invasion of Equestria and has to tell Spark Wheel she's really the changeling infiltrator Nictis. Spark is hurt and betrayed that a) the mare he loves never existed, and b) [[FalseFriend she only befriended him as a foal]] to [[EmotionEater feed on his crush]]. Nictis [[BecomingTheMask really has grown to love Spark]], but has lost his trust after revealing his lifelong deception. They never do reconcile.

[[folder:Films -- Animated]]
* Done in ''WesternAnimation/ScoobyDooAndTheAlienInvaders'' when Shaggy fell in love with a girl who was heavily into '60s culture. [[spoiler:She turned out to be a GreenSkinnedSpaceBabe in disguise (her clothes and mannerisms having been a result of AliensStealCable), and had to leave Earth at the end of the movie.]]
-->'''Velma:''' When I said there was someone out there for you, I didn't mean [[spoiler:out ''there'']].
* ''Franchise/{{Shrek}}'':
** Played with in ''WesternAnimation/Shrek1'': Princess Fiona finds out that the knight who saved her, the title character, is an ogre. Fiona is taken aback, but continues to travel with him anyway. One reason is because, before they got to know each other, he was only planning to take her to Lord Farquaad, rather than for himself. The other reason is [[spoiler: the fact that she's cursed to turn into an ogre herself by night.]]
** The ending of ''WesternAnimation/Shrek2'' has [[spoiler:Lillian discovering that her husband Harold is actually a frog who was turned into a human by the Fairy Godmother]]. Like Fiona [[spoiler:their daughter]] she takes it very well.
[[/folder]]

[[folder:Films -- Live-Action]]
%%* ''Film/TheBermudaDepths'': Magnus and Jennie.
* ''Film/{{Dagon}}'': DoubleSubverted, where the male lead has dreams about a beautiful mermaid, then he meets her in real life and she appears to be human, even starting to make out with her... until he notices the tentacles emanating from her lower body.
* ''Film/DarkAngelTheAscent'': Veronica doesn't reveal that she's a demon until after she and Max have already made love. He's a bit startled by her claws and wings at first, but ultimately doesn't mind.
* ''Film/TheDeathsOfIanStone'' has a peculiar relationship to this trope. In the very beginning, everyone in the setting seems clearly human or clearly inhuman. [[spoiler:The second iteration of the main character's DreamWithinADream reveals that his secondary love interest is both [[EldritchAbomination completely inhuman]] and willing to kill him if he finds out about it. A later iteration reveals that [[TomatoInTheMirror he's inhuman too]], albeit with LaserGuidedAmnesia. Unlike most examples, this isn't about the human primary love interest learning to accept him--rather, ''he'' learns to think and feel like a human.]]
* ''Film/GalaxyQuest''. Fred Kwan and Lailari, who he thinks is a HumanAlien. He's quite wrong. [[NightmareFetishist But he doesn't care]].
* In ''Film/{{Halloweentown}} III,'' Dylan (a [[HalfHumanHybrid half-human]] [[MageSpecies warlock]] who DoesNotLikeMagic) gets involved with a girl [[PairTheSmartOnes just as dorky as he is]], only to find out she's a furry pink [[AllTrollsAreDifferent troll]] wearing a costume. He reacts badly, tries to apologize, only for ''her'' to respond that he looks weird and ugly to her too. By the end of the movie they've made up and are about to have their big kiss...but she suddenly backs out of it, he acts relieved, and they agree that they're BetterAsFriends.
%%* ''Film/LetTheRightOneIn''. A dark puppy-love version. A Boy meets a mysterious girl and makes friends with her, only to discover, later, that she's a vampire responsible for a series of local murders. [[spoiler:Also, "she" is actually a castrated boy.]]
%%** The 2010 remake ''Film/LetMeIn'' has the same. Without the twist of the original.
* ''Film/TheManWhoFellToEarth'' gender flips and deconstructs this with alien Thomas Jerome Newton and his Earthly mistress Mary-Lou. They actually consummate their relationship before he reveals his true, RubberForeheadAlien form to her. Once he does, their already-troubled relationship is only further damaged -- out of his disguise, he's not capable of lovemaking in the human manner, and she finds him physically hideous anyway. [[spoiler:They ultimately fall out of love with each other.]]
%%* ''Film/{{Splash}}'': A variation on the classic mermaid-falls-in-love-with-a-human story; she can appear fully human unless she gets wet, which comes as quite a surprise to him the first time it happens.
* The ''Film/TalesFromTheDarksideTheMovie'' movie has a DownerEnding version of this. An Artist down on his luck sees a horrible Gargoyle slaughtering a friend of his. The Gargoyle promises to let him live if he never, ever, EVER!!! tells another living soul about this and he agrees. And then all of a sudden his entire life has an upswing. That very night he meets and falls in love with a mysterious woman who loves him back. She mentions she knows a famous gallery owner willing to give his art a chance... Cut to ten years later. He is a famous artist, they have two lovely children, their love is greater than ever but he is constantly burdened by the horrible secret he carries within him, the ONE thing he hasn't shared with her— and you can probably see where this is going...

[[/folder]]

[[folder:Literature]]
%%* ''Literature/BloodAndChocolate'': Boy meets werewolf. One of the more [[SlidingScaleOfIdealismVersusCynicism cynical]] cases, as [[spoiler:not only does their relationship [[StarCrossedLovers not work out]], it's implied that it's [[HumansAreBastards impossible for humans not to hate and fear werewolves]].]]
%%* Literature/{{Discworld}}: 2-meter tall dwarf meets werewolf.
%%* ''The Gravesavers'' by Canadian author Sheree Fitch had a girl meet a boy, who [[spoiler:turned out to be a ghost from the wreck of the RMS Atlantic]].
%%* ''Literature/LetTheRightOneIn'': as with the movie, a young boy meets a strange girl, and an innocent childhood romance develops, before he discovers that she's a bloodthirsty vampire. [[spoiler:The book is even more explicit than the movie about the fact that Eli is a mutilated boy.]]
* In Philip José Farmer's ''Literature/TheLovers'' a man from an oppressive puritan theocracy meets the girl of his dreams in another planet. Except that she's actually a ''lalitha'' [[spoiler:a highly evolved arthropod]].
* In ''Literature/TheLunarChronicles'', the cyborg Cinder falls in love with the human Prince Kai, but at the ball is revealed to be a cyborg [[spoiler:and a member of a race of people living on the moon called Lunar]].
* In the ''Franchise/{{Mistborn}}'' novel ''[[Literature/WaxAndWayne Shadows of Self]]'', [[spoiler:an insane, homicidal, ancient shapeshifter reveals that it was Wax's [[FakingTheDead deceased]] wife Lessie, and that their god had sent it undercover to protect Wax before it [[BecomingTheMask genuinely fell for him]]. Since Wax had killed "Lessie" by accident, and had just mortally wounded the shapeshifter, he takes it... [[HeroicBSOD poorly]].]]
* In ''Literature/MysteriousWaysADivineComedy'', [[http://alicrow.com/chapter-64/ Lilly (angel, and dragon-slayer) finds out that Alex is actually two-thirds dragon]].
%%* ''Literature/NyarukoCrawlingWithLove'' takes this to a comparative extreme: boy meets [[Franchise/CthulhuMythos Nyarlathotep]].
* In ''Literature/TheShadowhunterChronicles'':
** [[MageSpecies Warlocks]] are born after a demon has sex with a human. Human parents (almost always women) realize much later that they were intimate with a demon because their child has clear non-human characteristics. Many demons can change their shape so that they are mistaken for humans. However, some cannot, and the result is [[HotSkittyOnWailordAction much more terrible]].
** [[TheFairFolk Fairies]] sometimes have sexual or romantic encounters with humans. Fairies can very often pretend to be humans, so that the respective person only learns in the course of the relationship that his partner is not a human.
%%* Creator/HarlanEllison has a short story called "She's A Young Thing And Cannot Leave Her Mother" where boy meets [[spoiler:cave-dwelling mutant cannibal descendant of Sawney Beane]] (a.k.a. "Camilla").

[[folder:Live-Action TV]]
* In ''Series/BeingHumanUK'' Season 2, ghost Annie goes on a date with human Saul [[spoiler: Except he's not so normal himself...]], and seemed to have feeling towards normal human Hugh. Also vampire Mitchell is falling for regular human Lucy.
* ''Series/{{Bewitched}}'': Darrin Stephens learns his wife Samantha is a witch while on their honeymoon, forming the central conflict between her witch side and his desire to live without magic.
* ''Series/BigWolfOnCampus'' in the second season has this. Human girl [[BadassNormal Lori Baxter]] dates werewolf Tommy Dawkins. However, towards the end of the season, [[spoiler:they break up because their relationship was getting in the way of their monster fighting.]]
* ''Series/BuffyTheVampireSlayer'':
** Subverted with Tara, who ''thinks'' she's a demon and goes to considerable length to prevent Willow from finding out. Turns out she's not; it was just part of her abusive family's "spin to keep the ladies in line".
** Xander has been referred to as a "demon magnet", as a good deal of the girls he falls for turn out to be not so human. In "Teacher's Pet" he has crush on a substitute teacher, who is actually [[spoiler:a giant praying mantis that wants to mate and then eat his head.]] He later falls for "Inca Mummy Girl", and in season seven he goes on a date with a nice girl who [[spoiler:changes her eye colour and offers him as a sacrifice to open the Hellmouth.]]
** Buffy discovers that Angel is a vampire ''while'' making-out.
** Willow's relationship with Oz is blooming, and then she discovers he is a werewolf. (Though he only found out less than a day before she did.)
** Played with extensively in Season 4: Riley discovers Buffy is the slayer (which means demon infused) as she discovers he is a superagent (which is ultimately revealed to be a little bionic).
** In a novel, the slayer Athena/Nina learns that her friend Leo, with whom she has been in love for years, is a half-demon. At first she is scared, but also because she mistakenly thinks he is a murderer. When the matter is resolved, she takes it surprisingly well. At the time of this unveiling, both are not actually lovers, but are already in love with each other.
* ''Series/Charmed1998'': Midway through season 1, it's revealed that Piper's (then) boyfriend Leo is not human and that he's a whitelighter. There had been a few [[RunningGag comedic suspicions]] about him prior to the reveal due to Piper's bad luck with men (her boyfriends often ended up being revealed as evil warlocks) but the reveal that he's their guardian angel does come as a shock to all of them. Since whitelighter/witch romances are traditionally forbidden, the couple do spend most of the entire eight seasons struggling to make it work before everything finally works out in the end. Subverted in that whitelighters are actually born human but are transformed into whitelighters and can be turned back into humans if the occasion demands. All three of their children are half-whitelighter, half-witch.
* ''Series/DoctorWho'': In [[Recap/DoctorWhoS30E7TheUnicornAndTheWasp "The Unicorn and the Wasp"]], the Unicorn refers to the nickname of a jewel thief. The Wasp refers to either Lady Eddison's former lover, who appears only in flashback, who initially appeared human but then revealed himself as a member of an alien race that resembles giant wasps, or [[spoiler:the child they conceived together, who's also able to take human form, though he became a priest and thus never had a lover to reveal himself to]].
* ''Series/InterviewWithTheVampire2022'': In "[[Recap/InterviewWithTheVampire2022S1E1InThroesOfIncreasingWonder In Throes of Increasing Wonder...]]", Louis de Pointe du Lac believed that Lestat de Lioncourt was human throughout their friendship and during [[TheirFirstTime their first sexual encounter]]. However, he starts to suspect that Lestat isn't human when the latter incessantly bombards his mind with telepathic demands to "Come to me/''Viens à moi''," and Louis even declares during his [[{{Confessional}} confession]] to Father Matthias that "I laid down with the Devil." Lestat finally drops his mortal façade when he enters the church and lets Louis witness firsthand his bloodthirsty vampiric nature. Although Louis is scared of Lestat, the latter's LoveConfession is both heartfelt and persuasive enough that Louis willingly receives the Dark Gift from Lestat so they can be together forever.
* The main character of ''Series/{{Moonlight}}'' was turned into a vampire by his wife on their wedding night, who forgot to [[IHateYouVampireDad run it by him first]] before doing so.
%%* ''Series/NightGallery'', a show famous for its twist endings, liked this one.
%%** "The Phantom Farmhouse": she's [[NinjaPirateZombieRobot a werewolf who's actually a ghost]].
%%** "Lindemann's Catch": she's a mermaid.
%%** "The Girl With the Hungry Eyes": she's a psychic vampire.
%%** "Death on a Barge": she's a regular vampire.
* Red's backstory in the first season of ''Series/OnceUponATime'' includes this. [[spoiler:Her boyfriend didn't know he was dating a werewolf. Course, Red didn't know that either, and, thinking it's he who is the wolf, ties him up before the change can take him. Then she turns into the wolf and kills him. Oops.]]
* ''Series/TheOuterLimits1995'':
** In "[[Recap/TheOuterLimits1995S2E7FirstAnniversary First Anniversary]]", two aliens are stranded on Earth use their power to fool people's senses in order to pass as human. Specifically, as [[UglyGuyHotWife very pretty human women who act romantically interested in some rather plain-looking men]]. Unfortunately, people tend to become resistant to their power after about a year or so, and the men who marry them tend to GoMadFromTheRevelation after seeing their true appearances. (In an aversion of TakeOurWordForIt, when they let down their disguise, it's on-screen -- and they really are horrifying.)
** In "[[Recap/TheOuterLimits1995S4E15Mary25 Mary 25]]", the Innobotics Corporation programmer Melburn Ross disables the fail-safes of the android nanny Mary 25 which prevent her from harming humans so that she will kill his boss Charlie Bouton, who regularly beats his wife (and Melburn's old girlfriend) Teryl. [[spoiler:Three months after Mary 25 does so and is dismantled, Melburn finds one of the android remote-control devices in Teryl's bedroom. When he presses the button, Teryl enters sleep mode in the same fashion as Mary 25 and it is revealed that she too is an android. Charlie killed the real Teryl and replaced her with this copy. Melburn realizes that the android Teryl manipulated him into reprogramming Mary 25 so that she could be rid of Charlie once and for all. The android Teryl counters that she wanted to continue the original's relationship with Melburn, who would be a much better father to "her" children Brook and Brandon than Charlie ever was. The episode ends with Melburn backed up against a wall, terrified of the android copy of his former lover.]]
* Isabel in ''Series/{{Roswell}}'' married Jesse Ramirez, who was human, but he didn't find out Isabel was an alien until later in season 3.
%%* ''Franchise/StarTrek'' '[[Franchise/TrekVerse verse]]: Boy meets android, or hologram, or Leanansidhe [-IN SPACE-], or astral projection of someone else's subconscious self, or dead {{Redshirt}} with instincts of aliens who resurrected her, or long dead to ''stay'' and the messages to each other are going through a time warp, or woman whose presence will erase bits of your memory relating to her once she's out of sight... the list goes on. The girls' dating lives are no easier, just not featured quite as often.
* ''Series/TrueBlood'' has Tara and Sam, human meets shifter.
* ''Series/WolfLikeMe'' has Gary discovering that Mary is a werewolf at the end of episode 2. While initially taken aback and trying to distance himself from her (which is not helped by the fact she confesses to [[spoiler: having previously eaten her husband and a whole family]]), they manage to make it work by the end of episode 4.
* On ''Series/TheVampireDiaries'', Elena unexpectedly meets Stefan and feels an instant connection with him in season one. However, Stefan is hiding a deep, dark secret: he is a century old vampire. As Stefan and Elena fall harder for each other, Elena eventually discovers that Stefan is a vampire.

* "The Alien Jellyfish Song" by Chris Conway is about an alien who spends some time on Earth and hits it off with a bartender. After they return to his home planet, he reveals his true form to her, [[spoiler:and then she reveals that she's ''also'' an alien who had spent the past decade stranded on Earth]].
[[/folder]]

[[folder:Myths & Religion]]
* Subverted in an Arab folktale. A daughter of a ''ghoul'' (human-eating monster) winds up with some of its magical powers. She nearly gets married to a prince except for the presence of another girl. She throws herself into an oven and reforms, leaving fresh bread ready in the oven to start a welcoming feast for the prince. The other girl claims similar abilities, throws herself into the oven, and burns to death.
* In Myth/GreekMythology there were a few examples of this type. For instance, male gods would occasionally reveal who they were on taking leave from the woman they had just impregnated. In a more spectacular example, Hera posed as an old woman to trick Semele, one of her husband Zeus' lovers, into getting him to promise to do her a favour and then make that favour to show himself to her in his true form. She did not survive the experience.
* The Huldra women of Norwegian folklore become mortal and gain souls when they are married to a man. However, they still keep their magic and freakish strength, much to the peril of unfaithful husbands.
* OlderThanPrint: [[AsianFoxSpirit Kitsune]] are subject to this trope. ''Kitsune''-wives usually left when their true nature was exposed, but in at least one tale, the husband called after her, reassuring her of welcome, so she returned, but only at night.
* The medieval story of ''Melusine'', which dates back at least to the 12th century, tells of a knight marrying a woman called Melusine:
** One version is she marries him on condition that he never look at her naked. One day his curiosity got the better of him and he peeked while she was taking a bath. To his horror he saw that she had a snake-like tail, showing she was a water-sprite or mermaid. When she realized that her secret was out, she left through the window, never to be seen again. In the most common version of the story, this Melusine is the supposed ancestress of the French Lusignan family. How this could be the case when her husband couldn't see her naked is probably best ignored.
** Another version had the condition that she be allowed to be alone, locking herself in her room, every Saturday or Sunday till noon, and the knight would never try to look at or visit her then. This was because she was cursed -by her mother!- to turn into a serpent from the waist down during that time, and did not wish him to know. All of her children were born with some slight deformity, but were otherwise brave, good, and fortunate. But the whispers that the children were deformed because they were not his became too much for the knight, and he spied on her. When she found out, she left him, never to be seen again.
* The {{Selkie|s}} myths of [[Myth/CelticMythology Ireland]], almost exactly the same as the kitsune-wives, but the men capture the women by hiding the pelts that let them turn back into seals.
* There's a Myth/{{Japanese myth|ology}} about [[{{Youkai}} Yuki-Onna]], which plot was used for the ''Film/TalesFromTheDarksideTheMovie'' example mentioned above.

[[folder:Video Games]]
* This is one of the possible endings in the InteractiveFiction game ''VideoGame/{{Afflicted}}'', where you are a restaurant inspector [[spoiler:who stumbles across a feud between vampires]]. After the player [[spoiler:reassembles Sofia's body, he can agree to be turned into a vampire himself;]] if you simply leave Nikolai's Bar afterwards, [[spoiler:Sofia ends up moving in with you]].
* ''VideoGame/{{Catherine}}'': The blonde lady of your dreams turns out to be [[spoiler:a succubus sent to you]]. ''Full Body'' would later add [[spoiler:an alien]].
%%* ''VideoGame/Disgaea2CursedMemories'': Boy meets demon. Turns out to be a non-issue since ''VideoGame/DisgaeaHourOfDarkness'' already showed that human/demon {{Half Human Hybrid}}s are possible (and for those who haven't played it, a character from that game explains it anyhow). [[spoiler:And it doesn't matter anyway, as boy is a demon too but doesn't realize it]]. Of course, by that point, it's stopped being "boy meets demon" and started being "boy meets [[spoiler:reincarnated God Of All Overlords]]."
%%* ''VideoGame/FireEmblemTheBlazingBlade'': Boy meets [[spoiler:dragon]].
%%* ''VideoGame/FireEmblemPathOfRadiance'': Boy meets cat(girl) in his backstory. [[spoiler:They break up before the game starts.]]
* An inversion of this happens in ''VideoGame/MasterDetectiveArchivesRainCode'' where [[spoiler: the main character, Yuma Kokohead, meets a girl name Kirumi Wendy during a case he was investigating in Kanai Ward. However, Kirumi would later to be revealed as a [[OurHomunculiAreDifferent homunculus]] where the original Kirumi was already killed off and the Kirumi Yuma meets is her undead replacement. However, despite this and even knowing she is immortal, Kirumi is still very much attracted to Yuma and even leaves Kanani Ward with the Book of Death in hopes of reuniting with him instead of waiting for him to return as he promised.]]
* Teddie's crush on Labrys in ''VideoGame/Persona4Arena'' inverts this. He meets her thinking she was a normal human girl, feeling ashamed of his own [[BecomeARealBoy non human nature]] when it is revealed to her soon after. The eventual reveal that she isn't human either, but an amnesiac [[RidiculouslyHumanRobots battle android]] only makes him ''more'' enthusiastic about winning her for himself, if anything.
* There was a subplot in the Game Boy Advance RPG ''VideoGame/{{Robopon}} 2'' based around this. You have to round up a group of alien schoolgirls on a field trip from the moon (ItMakesSenseInContext) and one of them disguises herself as a human and has a guy fall in love with her. You chase them all over the world map. When she finally admits to him that she's an alien, he says that he'll love her no matter what.

* ''WesternAnimation/JohnnyBravo'':
** Parodied by a ShowWithinAShow soap opera wherein a woman confesses to her lover that she is not what she appears, revealing herself to be a giant dalmatian.
** In another episode, Johnny goes on a date with a deer. No, not a humanoid deer, part-deer human, anything like that - an actual, albeit talking, deer.

** One episode plays with this trope, in that Johnny goes out on a date with a vampire woman who the audience knows from the start isn't human, but he remains blissfully unaware until the episode's end. She ends up going back to her old (vampire) boyfriend at that point, and Johnny handles the vampire thing pretty well.
* ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtles'' has such a moment in the backstory, wherein [[spoiler:action film star [[WorldsGreatestWarrior Lou Jitsu]] learned his girlfriend Big Mama was a spider {{Yokai}}.]] This probably would've gone over better [[spoiler:[[EtTuBrute if she hadn't revealed this as she was kidnapping him]]]].
