* In ''Man's Best Friend'', a Yaoi manga by Kazusa Takashima, a dog falls in love with his teenage-boy owner and gains the ability to transform into a hunky man.

* ''Manga/InuYasha'' has a number of romances between humans and (half)-{{youkai}}, but the youkai are always either naturally humanoid (Inuyasha, Koga) or have a humanoid ShapeshifterDefaultForm (Sesshomaru, Inuyasha's father).\\
In a slightly comical aversion, the [[{{Raiju}} Thunder Brothers']] father was visually indistinguishable from a human (like Hiten), but their mother was a squat, yellow-skinned humanoid with a large conical head (like Manten). For their species of youkai, this is apparently completely normal.

* In ''Literature/TheTwelveKingdoms'' (both anime and novel) there's a fair bit of subtext between Rakushun and Youko...and Rakushun is a giant, vaguely humanoid rat (he's just a rodent of unusually large size that can stand on his hind legs) who can turn into a human at will, though he prefers his rat form.
* A filler episode of ''LightNovel/{{Slayers}}'' has a man fall in love with a fish person. They want to find a potion that will 'allow them to live together', thinking this means that it will turn the fish-woman into a human woman. While this is true, it also turns the man into a fish-man. They are perfectly happy with this.

* There was possibly one story, ComicBook/KryptoTheSuperdog turned into a human and formed a relationship with a woman.
* ComicBook/{{Supergirl}}:

* Alan Moore once wrote a story about ComicBook/SwampThing's girlfriend noting that Lois and Superman have essentially the same relationship as they do. After she got arrested for "Crimes against nature", leading to Swamp Thing using his plant powers to turn Gotham City into a jungle, Batman pointed this out to the mayor, who panicked and dropped the charges.
* Franchise/XMen: Beast's girlfriend left him when he went from blue-hairy-ape-man-thing to blue-hairy-cat-man-thing, because even with all the {{fantastic racism}}, that was the point that people started comparing their relationship to bestiality. Later, poor Beast gets feelings for a cat-girl, who actually turned out to be more cat than girl. Seems mutancy is not just restricted to homo sapiens.

** This is also the comic which features a human having sex with a centaur several times before the centaur had sex (offscreen) with a horse--the 'curse' of being part horse transferred with sex, so the horse wound up with six legs afterwards.

* Inverted in ''WesternAnimation/BeautyAndTheBeast'', although that one still gets lots of d'awwww....

* Jim Butcher's ''[[Literature/TheDresdenFiles Fool Moon]]'', in covering the ''entire'' range of OurWerewolvesAreDifferent (minus the traditional "get bitten and become a werewolf" thing, which really ''is'' only in the movies), includes wolfweres (wolves that can take human form rather than the other way around). And one of them has a romantic relationship with a human who's cursed to turn into a wolf.
* Poledra in the ''[[Literature/TheBelgariad Belgariad]]''. She's a wolf, who takes the form of a human because she loves Belgarath, a human who can take the form of a wolf. We get very little explanation for why she is the only wolf known able to do this and live for thousands of years. Her expressions on the subject, irritating as they are ("what is time to a wolf?") are less than informative.

* There's another example from the [[Literature/TortallUniverse Trickster duology]] written by Creator/TamoraPierce - Nawat is a crow who becomes human after falling in love with the protagonist. At first he continues to act somewhat like a crow, but she doesn't start to return his affections until some time later, once he's started to act more human.

*** That, and the fact that it's implied that Gavin is the descendant of a yennork--a werewolf who isn't able to morph.
----> "You see, a yennork would go off and be a human or be a wolf but they'd still be carrying the werewolf...blood, and then they'd marry and have children...or pups...and, well, that's where the fairy-tale monsters come from. People with a ''bit'' of wolf and wolves with that extra capacity for violence that is so very human." She sighed, and glanced momentarily at Gavin.

* Any one person that's in love with a werewolf in the Literature/{{Twilight}} universe. Sure, they originally were human so it may be a subversion in that regards, but they're still large wolf like things that don't really look like wolves in the movies.

* Numerous relationships between humans and aliens on ''Franchise/StarTrek.'' Captain Kirk was famous for [[strike:fucking aliens]] "BoldlyComing where no man has gone before".
** And copied on AffectionateParody ''Film/GalaxyQuest'' with "Jane Doe", who is actually a tentacle monster. At one point, GlamourFailure ''does'' give us a couple seconds of a human-on-squid-thingy makeout session.
* Odo and Kira on ''Series/StarTrekDeepSpaceNine''. She's a [[RubberForeheadAlien human with ridges on her nose]], he's naturally a puddle of goo.
* Both subverted and played straight in ''Series/{{Farscape}}''. John's dad tells Aeryn outright that he isn't bothered by her relationship with John since he doesn't think of her as an alien. However, in the TV program they intercept from Earth later, there is quite a lot of debate over whether or not Aeryn is pregnant with John's child and how {{Squick}}y it would be if she was.
* In ''Series/BuffyTheVampireSlayer'' we have Buffy who has relationships with vampires. And it's an ongoing joke with Xander that demons are attracted to him.
** Not to mention that Willow's first on-screen relationship was (unknowingly) with a demon who had been turned into a magical book, who was then turned into computer data, who then turned into a robot...
* The Doctor and Rose in ''Series/DoctorWho'', as well as the Doctor's numerous other flirtations with humans. Only Donna seems to have a problem with the whole 900-year-old alien thing. In the case of Time Lords, it's not the look that sets them apart from your traditional Star Trek type alien; The Doctor is centuries old and has seen and done so much that he's considered mysterious and alien ''by the standards'' of those who are mysterious and alien.
* ''Series/{{Charmed|1998}}'' did this right from the pilot. Between them the Halliwells have dated and in some cases married demons, half-demons, warlocks, angels, ghosts and god only knows what else.
--> '''Pheobe''': ...which means I'm dating a warlock.\\
'''Paige''': Been there, done that.

* ''Film/GuardiansOfTheGalaxyVol2'' gives us Ego and the many women he created offspring with, including [[spoiler: Peter Quill's mom]]. His true form? You might know him as Ego the Living Planet. His human avatar is just that, a construct he uses to interact with other races.
** This also makes [[spoiler: any romance Peter the half-Celestial has]] an instance of this.
[[/folder]]

* [[spoiler:Makoto, one of the girls Yuuichi can fall in love with]] in ''VisualNovel/{{Kanon}}'' is actually a fox.
** Similarly, [[spoiler:Shima]] in ''VisualNovel/{{Clannad}}'', the lover of [[spoiler:Misae]] who turned out to be [[spoiler:a cat whom she would later take in]]. Both are played with as much TearJerker potential as possible.

%%%* A robot falls in love with the protagonist of ''VisualNovel/DaCapo'' in one of the extra two routes. Apparently this sort of thing is intended to happen as she apparently has a hymen to break and gets pleasure from sex. But um until that point in the story...%%% Until that point in the story what?

* ''WesternAnimation/TheLastUnicorn'' is fully sentient in her original form, so it may not fully count. But in a poignant scene there's still a slight moment of {{squick}}/hilarity when Lir, who's in love with her as a human finds out who she really is and says "Unicorn, mermaid, sorceress, no name you could give her would surprise or frighten me. I love whom I love." Schmendrick says "Well, that's a very nice sentiment, but when I turn her back into her proper shape..." and Lir just repeats stonily: "I LOVE WHOM I LOVE."
* ''WesternAnimation/AdventureTime'': Finn is the only for-sure human in the world at the moment and lusted after by a whole harem of weird princesses. However, the only ones for whom serious romantic interest has been brought up are Bubblegum (a candy person), Marceline (a half-demon vampire), and Flame Princess (a fire person).

* While it remains a point of contention within the scientific community whether [[OriginalMan archaic humans such as Neanderthals and Denisovans]] should be considered subspecies of ''Homo sapiens'' or different species altogether, there are definite physiological differences between us to the point of it nearing the UncannyValley. In spite of this, one of the [[ClashOfEvolutionaryLevels several reasons for their extinction]] is that they were partially [[HalfHumanHybrid assimilated into our genome through crossbreeding]], with Europeans and Asians carrying around 2% Neanderthal DNA on average.

** Garaku looks human (rather arbitrarily, as tsukumogami like him are usually {{Animate Inanimate Object}}s), fell in love with Mei, and Matsuri [[ImaginaryLoveTriangle sees him as a romantic rival for Suzu's affection]]. Ironically, despite his humanoid body, [[RomanticAsexual his attraction to Mei is completely nonsexual]].

In a slightly comical aversion, the Thunder Brothers' father was visually indistinguishable from a human (like Hiten), but their mother was a squat, yellow-skinned humanoid with a large conical head (like Manten). For their species of youkai, this is apparently completely normal.

** Played strangely in ''Super S'': Chibi-Usa spends the season nursing a PrecociousCrush on Pegasus, though [[ObliviousToLove he doesn't seem to notice]]. It turns out Pegasus' original and true form was a humanoid named Helios, but Chibi-Usa and the audience are informed of such ''long'' after she'd been shown infatuated with him. Apparently, if you're going to be into InterspeciesRomance in this series, you're going to have to be okay with their normal form ''before'' you ever get to see them in a human form.

* Played strangely in ''Franchise/SailorMoon'': Chibi-Usa and Kakeru have some romance hinted with Pegasus/Helios and Luna, respectively. The latter both ''have'' human forms, but spend most of their time on-screen and with their counterpart as a winged horse and cat. Apparently, if you're going to be into InterspeciesRomance in this series, you're going to have to be okay with their normal form ''before'' you ever get to see them in a human form.

** After she got arrested for "Crimes against nature", leading to Swamp Thing using his plant powers to turn Gotham City into a jungle, Batman pointed this out to the mayor, who panicked and dropped the charges.

* ''Manga/RanmaOneHalf'': The Musk Dynasty turned animals into women using the [[TransformationRay Cursed Springs]] so they would [[LamarckWasRight bear children with]] [[AnimalThemedSuperbeing animal superpowers]]. Disturbingly, there's no sign animals turned into humans by the curse even become sapient.

* ''Manga/RanmaOneHalf'': The Musk Dynasty turned animals into women using the Springs in order to have children with them.

* In ''Literature/TheTwelveKingdoms'' (both anime and novel) there's a fair bit of subtext between Rakushun and Youko...and Rakushun is a giant, vaguely humanoid rat (he's just a rodent of unusually large size that can stand on his hind legs) who can turn into a human at will, though he prefers his rat form. There's also a not-so-implied unrequited love between the former Queen of Kei and Keiki, the shape-shifting Unicorn...and then there are in turn shippers who swear by a KeikixYouko coupling.

* Sora of ''VisualNovel/Ever17'' falls in love with Takeshi. While he doesn't really reciprocate, he does find her very beautiful and the characters in story go awww... as well.

* ''Manga/AyakashiTriangle'': Most ayakashi are sapient.

* ''Manga/InuYasha'' has a number of romances between humans and (half)-{{youkai}}, but the youkai are always either naturally humanoid (Inuyasha, Koga) or have a humanoid ShapeshifterDefaultForm (Sesshomaru, Inuyasha's father).

%%* ''Anime/AngelTales'' (Tenshi no Shippo).
%%* ''Anime/YesPrettyCure5''.

* ''Manga/InuYasha'':
** [[HalfHumanHybrid Inuyasha]] and his relationship with Kagome.
** Inuyasha being a half dog {{youkai}}, had a human mother and a {{youkai}} father.
** While not canonically a relationship, the Sesshoumaru and Rin shippers that read into subtexts fit this trope. Despite that Rin is only the MoralityPet in the series, and is about elementary school age. Also during his introduction (that took three episodes), Sesshoumaru transformed into a giant dog that Inuyasha said was his true form. Also, with Myouga pointing out that their father used illusions or spells to appear human...yeah it's really a support of [[{{Squick}} Giant Dog on Little Human Chew Toy]] if you discount the human transformation.

* Chibi-Usa and Pegasus/Helios from ''Franchise/SailorMoon''. (He's called Pegasus ''because he's a pegasus.'' He does have a human form, but it's not seen very often - we're talking a good bit of human-and-talking-horse ShipTease.)
** Also, Luna (cat) and Kakeru from same. Luna has spent even less time in human form. In general, if you're going to be into InterspeciesRomance in this series, you're going to have to be okay with their normal form before you ever get to see them in a human form, unlike the many stories where you mostly see a cute girl/boy and only get glimpses of something stranger.

* ''Manga/PetShopOfHorrors'' did this a few times, usually more towards the subtext end of the scale.
* This was more or less the entire premise of ''Manga/GuruGuruPonChan''.
* ''Manga/RanmaOneHalf'', with the Musk Dynasty, who turned animals into women using the Springs in order to have children with them.

* ''VisualNovel/{{Tsukihime}}'': because [[MemeticMutation "a cat is fine, too"]].

* There are the homunculi from ''Manga/FullmetalAlchemist''.

* The anime ''Anime/SoulEater'' features weapons such as scythes, swords and guns that have humanoid forms. And can go so far as to be able to reproduce with humans. Maka, one of the main characters, is a progeny of a human/weapon relationship. Does not apply at all for the weapons. They are all humans, they are just humans who have special powers. Although this may somewhat apply with the witches, they may be immortal therefore not human, and it does apply with Blair the cat.
** Also applies to the shinigami, who are not human, but in Kid's case just look as though they are (not so much for Shinigami, but if Mosquito is to be believed he either can do or has done in the past).

* Inverted in the 2018 reboot of ''WesternAnimation/SheRaAndThePrincessesOfPower''. Hordak has an alien appearance, being almost seven feet tall with bat-like facial features, black-lidded crimson eyes, fangs, claws, and blue skin. However, the romantic tension between Hordak and the humanoid Entrapta is treated as a serious plot development, with none of the other characters finding it odd or squicky.

* Inverted in ''Disney/BeautyAndTheBeast'', although that one still gets lots of d'awwww....

** Ludmilla Cake and Lupin in ''Discworld/ReaperMan''. She's a human who turns into a [[WolfMan Wolf Woman]] at full moon. He's a wolf who turns humanoid at full moon. They apparently have a relationship for one week a month, and the rest of the time Lupin is kind of Ludmilla's mother's pet dog. Which is a lot {{squick}}ier written like that than it was in the book...

** Inverted ''Discworld/TheFifthElephant'', where a wolf called Gavin (well, he once ate someone named Gavin) is said to have had a very Carrot-like relationship with Angua. The {{Squick}} mitigation comes less from him being a smart wolf, and more Angua not being human all of the time she's with him.

** Nanny Ogg's pet cat Greebo, in ''Discworld/WitchesAbroad'', picked up a new skill: he can turn into his human male equivalent, and invokes AllGirlsWantBadBoys. He retained the skill, and uses it again in ''Discworld/{{Maskerade}}''.

* In the 2018 reboot of ''WesternAnimation/SheRaAndThePrincessesOfPower'', Hordak has an alien appearance, being almost seven feet tall with bat-like facial features, black-lidded crimson eyes, fangs, claws, and blue skin. However, the romantic tension between Hordak and the humanoid Entrapta is treated as a serious plot development, with none of the other characters finding it odd or squicky.

* In the 2018 reboot of ''WesternAnimation/SheRaAndThePrincessesOfPower'', Hordak has an alien appearance, being almost eight feet tall with bat-like facial features, black-lidded crimson eyes, fangs, claws, and blue skin. However, the romantic tension between Hordak and the humanoid Entrapta is treated as a serious plot development, with none of the other characters finding it odd or squicky.

* ''Film/GuardiansOfTheGalaxyVol.2'' gives us Ego and the many women he created offspring with, including [[spoiler: Peter Quill's mom]]. His true form? You might know him as Ego the Living Planet. His human avatar is just that, a construct he uses to interact with other races.
