Interspecies Romance - Television Tropes & Idioms

Played with in Inukami: During a Love Potion Yamato Nadeshiko incident, Keita thinks about getting some interspecies loving with Youko and/or five of the other girls, until he realizes his kids would be half-dog, and is promptly squicked about the whole thing. Kinda odd though since he knew at the time that Youko is a kitsune/fox.
Transformers: Kiss Play: A Japanese series where Moe Moe lolis had to fall in love and make out with Transformers to give them superpowers.
Nozomi (human) and Kouji/Coco (funny plush-looking tanuki-thing from another dimension), as well as Komachi (human) and Natsu/Nuts (funny plush-looking squirrel-thing from the same other dimension) in (you guessed it) Yes! Precure 5.
- Yes Pretty Cure 5 loves this trope. There's also all the subtext between Karen (human) and Milk (funny plush-looking rabbit-thing from that same other dimension). They are both female. Which leaves Rin as the only Cure not paired up with one of the mascots... and one episode centered around her and a ghost (not exactly different species, but close enough).
Shows up in most Mons series' Fan Fiction. Digimon, however, quite canonically gave some suspiciously Ho Yay-ish jealousy on Wormmon's part about Ken, as well as Juri's crush on Leomon, and Renamon seeming to admire Jianliang a little too much in one episode.
- Also, Mons in any series with sentient Mons will wind up paired with other Mons that are of completely different types. A Wailord can be as different from a Skitty as a human is, and unless the two species have a beef with each other, no one sees it as unusual.
- One of the girls with a crush on Ash is a legendary Pokemon. She even kissed him. Granted, she was in human-form at the time but still...
- "That's the last bath I'll take with my◊ Tentacool!" (That's canon, by the way.)
- Also,the Ash's Chikorita, Aipom and possibly his Gliscor (though s/he may just be just young and immature) have crushes on him. He also has a rather touchy feely friendship with his ambiguous gender of a Pokemon, Pikachu.
  - Not Ambiguous anymore. Pikachu was confirmed to be male in EP 603, along with Brock's Croagunk and Dawn's Piplup.
- Speaking of which, there's the matter of Dawn's Buneary, who happens to have a rather obvious crush on Pikachu.
And in Mahou Sensei Negima, the girls of the Unwanted Harem who have an actual interest in Negi include a vampire, her Robot Girl servant, a ghost, and perhaps a half-Tengu. Perhaps in the half-Tengu's case because she seems at least as interested in her (human) classmate/childhood friend. Also, Negi's Half-Demon best friend seems to be catching the attention of some of Negi's students as well.
- And then there's the recently revealed Magical Land, whose seems to be mostly populated with Humans, Petting Zoo People, some Funny Animals, even the odd demon. All of this little world is implied to happily mingle and reproduce without much regard for species.
The hentai The Elven Bride is about a human/elf couple (as implicated by the title), and deals with the Fantastic Racism aspects of this. Well, it mentions them.
- Hentai in general has a lot of this, usually women and monsters, though to be honest that's rarely romance.
- To be fair, romantic examples can appear, as in Pretty Lamia
- Don't forget the And Knowing Is Half The Battle of its sequel:
Remember, it only takes a little to get pregnant!
Kir from King Of Bandit Jing hits on everything with two X chromosomes to rub together, and though he always gets rebuffed, it seems to have more to do with his personality than the fact that he is a bird.
An example that's not as jarring because of the What Measure Is A Non Human moments: Yu Yu Hakusho and its human/demon romances, namely Sensui and Itsuki (human and demon/yaminade), Yusuke's ancestor Raizen and a female doctor (demon and human), and also Kuwabara and Yukina in the manga. Hell, you could count Yusuke and Keiko, as well, because of his demonic atavism.
Sailor Moon SuperS had Chibiusa fall in love with an ~~alicorn~~ winged unicorn named Pegasus. His true form was a human, so most people thought it was cute, but some people still got squicked.
- Partially subverted in that he was really after her mind, not body.
- And many people were squicked not by the implied bestiality issues as much as the fact that she was about 8-10 years old at the time while Pegasus was around 14-16 or so.
- Also, in the SuperS movie Black Dream Hole, it's heavily hinted that Chibiusa and Peruru have crushes on each other. Peruru is a Dream-Elf.
Hippo and Yuuri in Mermaid Melody Pichi Pichi Pitch covers all the bases. Hippocampus that turns into a penguin that turns into a human falls in love with a tropical fish that also turns into a human. Whew!
Lawrence and Horo in Wolf And Spice: a human and a trickster giant wolf who takes the form of a young girl (+ tails/ears) for almost all of the time. In volume 3 of the light novels, after suffering a great psychological blow, she says to Lawrence, "I am already alone. But, if I were to have a child, that would make two. Look, I am human in appearance right now, so it would not be impossible to be together with you who are a human, would it?"
Arguably, this is the entire premise of Kanokon.
- Thought the enture premise of Kanokon was extreme fanservice, with pinches of Shotacon.
The eponymous character of Inu Yasha is the product of a youkai (demon) and a human. He later goes on to have a romantic relationship with two human girls. Given the number of half-demons he runs into during the series (not to mention a very enamoured wolf-demon), it seems that humans are a common youkai fetish, and vice-versa.
In ''Alfred J. Kwak'', the titular character's nemesis, Dolf, is the son of a crow - who, judging from his only apparition in the very first episode, was quite narrow-minded - and a blackbird, an inheritance which is ashamed of, to the point of self-loathing; he even paints his orange beak black.
It ain't a canon example by any means, but would that all interspecies romances looked like this◊ (One's a cyborg, one's a vampire. Different species!).
It's mostly Human Aliens, and then there's the question of how you count Tenchi (he's part alien himself), but it's a central theme of the Unwanted Harem the poor kid has. Even the battleships have the hots for him. Well, two of the most powerful battelships in the galaxy, anyway. One manga shows a Terran girl making her case by being the only HUMAN interested in Tenchi.
Taken pretty seriously with the noted titles of Kanon and Clannad by Key Visual Arts. Both scenarios are demonstrated in a rather Tear Jerker route following the Beautiful All Along path, except...just replace beautiful with animal. The original visual novels take this detail a step further.
Gash Bell features Wonrei and Lien, the only human-mamodo team in the series whose relationship goes beyond friendship. Fortunately, since Wonrei is one of the few mamodo who actually looks like an adult human (and probaby the most human-looking mamodo of the entire series), the trope's usual creepiness is wisely averted.
One of the things the three series that made up Robotech had in common, aside from the Transforming Mecha, was a Green Haired Space Babe who falls in love with one of the human pilots.
In Inumimi, Yuichiro doesn't seem to be too interested in his dogs-turned-human (he pretty strongly averts All Men Are Perverts), but Elga at least seems to have a (non-sexual, thankfully) interest in him. (And Emina is not happy about it.)
In One Stormy Night, Mei the goat and Gabu the wolf are "friends", with a relationship dynamic much more like male lovers, albeit subvertedly Star Crossed Lovers, even opting, after the hardline disapproval of both their kin, to escape together to a distant place to be with one another forever. Gabu's carnal predatory instincts only add to this, seeming more like intense homoerotic attraction. In a later scene in the film, Mei agrees to be eaten if the one who eats him is Gabu, which gives Gabu an emotional breakdown, and they do not follow through. See also If Its You Its Okay.
Hayate and Vita of Magical Girl Lyrical Nanoha. A human and her beloved Ridiculously Human Guardian Knight Program.
- And for a more official example, we have Genya and Quint Nakajima, an Earthling and Mid-childan. Though since Quint was barren after sustaining near fatal injuries during a mission, she couldn't bear children. They found other ways to solve that problem.
Nerima Daikon Brothers has Ichiro and Yukika, both lusting for that panda booty
This happens a lot in Blue Drop, what with all the couplings between human women and Arume. Somehow it results in Half Human Hybrids, despite both parents being female and both parents being of different species.
Eureka Seven: Eureka and Sakuya were created for the express purpose of experiencing this, in order for the Coralians to study humankind.
Kyo Kara Maoh has Demon/Human relations. Although, for most of the series it is heavily frowned upon, to the point where Half-Demon Half-Human families have to live in their own villages. The squick factor is also pretty much nonexistant, since Demons are basically humans with magical abilities.
- Half demon half human offspring may or may not have magical abilities, as see by Conrart and Yozak (who have none), and El (who is ungodly powerful as a baby).
- There is also something involving a guy (presumably a demon) and a panda which, even by the standards of this series is just utterly insane.
1/2 Prince has a romance between a phoenix and a talking meatbun!
Bizenghast looks headed this way with Dinah (human) and Edrear (humanoid...bug...construct...thing). Edaniel also claims to have dated a human agent.
Yu-Gi-oh GX has Juudai x Yubel. Juudai swore his love to her after she was transformed from a human into a humanoid dragon, and that didn't change even after death and rebirth. He just forgot about it for a while. He got better. And so did she. There's also Taniya x Misawa, even though Taniya is fairly human looking. She can just turn into a tiger and has very pointed ears.
Given that Ahiru from Princess Tutu is a duck given human form, any relationship with her invariably involves some element of this, especially given the ending — Looks like Fakir isn't going to let the fact that they can't consummate get in the way of being together.
Three Dragonball examples: Goku/Chichi and Vegeta/Bulma (both Saiyan/human) and Krillin/Android 18 (human/cyborg, though it may not really count since 18 was a regular human before being cyborgized). Later on, Gohan/Videl (half-Saiyan/human).
- Given that none of the surviving Saiyans were female, it wasn't as if they had another option for reproduction.
One Piece has human and mermaid couples, and even a fishman and giant hybrid.
To Love Ru has a romance between a human (Rito) and at least two alien girls, Lala and Run.

Nightwing and Starfire (human/alien) in at least one continuity of the DC Comics universe.
- Same goes for their fellow Titans, Beast Boy/Changeling (human) and Raven (half demon.)
Professor Charles Xavier and the Shi'ar Empress Lilandra in X-Men.
- Made worse by the fact that Lilandra is descended from avian stock, Charles from primate stock. OTOH, the Celestials might have reengineered both breeds to make them compatible. The Shi'ar seem more primate-like than evolution would plausibly manage...
The Marvel comic book Howard The Duck had Howard (intelligent talking duck from an alternate reality) and Beverly (human).
- Played way too straight in The Movie, resulting in a Wall Banger.
The Kree superhero Captain Mar-Vell loved many a Green Skinned Space Babe, which is why all three of his children were hybrids - Genis and Phyla (Kree/Eternal) and Hulkling (Kree/Skrull). Hulkling is in a relationship with fellow superhero Wiccan, which is not only interspecies but also homosexual. Of course, his half-sister Phyla and her human girlfriend Moondragon have Les Yay. Or rather had.
Karolina (Majesdanian) and Xavin (Skrull) in Runaways.
Nova (human) and Green Skinned Space Babe (literally) Gamora, in Annihilation.
Scarlet Witch (mutant) was married to the android Vision for many years. Her brother Quicksilver married the Inhuman princess Crystal.
- The former might not be an example, since the Vision might have been designed to be compatible. Is an artificial person of human design a different species? As for Crystal and Pietro, the Inhumans and mutants are two branches of one breed anyway, so that doesn't really fit the trope.
Nightcrawler (mutant) and Cerise (Shi'ar).
Namor (human/Atlantean hybrid) married Green Skinned Space Babe Marrina, but also found time to pursue the human (and all-too-married) Invisible Woman.
- Atlanteans in the MU are a branch of the human race, so this would me more like interSUBspecies romance.
- Namor, as implied above, is the result of one of these pairings: human father and Atlantean mother. His cousin Namora has a human mother and Atlantean father. As they're effectively the only members of their kind, most any romance they pursue (aside from each other) is one of these.
The XXXenophile comics (porn with fantasy and science fiction themes) are naturally full of examples of this. Just in case the title didn't give it away.
- According to XXXenophile, even the weirdest aliens out there seem to be physically compatible with humans.
Lois and Clark are probably the most famous example of interpecies romance (even though he's a Human Alien).
- The Larry Niven essay Man of Steel, Woman of Kleenex goes into quite a bit of detail on the various issues regarding Kal-El's sex life, possibly farther than some would prefer.
Also from DC, John Stewart married Katma Tui (alien) and had a long-standing relationship with Merayn Dethalis (also alien). This seems to be common with John Stewart; he ended up with Hawkgirl in the Justice League cartoon.
Mossy earth elemental Swamp Thing and his human wife Abigail Arcane. Played with considering the nearby town finds out and convicts her of bestiality. Abby flees to Gotham City where the police hold her, causing Swamp Thing to go ballistic to free her. Batman finally talks the Mayor into giving in considering that if he wants to hold Abby for having a relationship with an non-human sapient being, then he'd better arrest Lois Lane, among others, for her relationship with an admitted extraterrestrial, Superman. Since busting the world's greatest superhero's girlfriend for bestiality would look very, very bad and ridiculous in the media, the Mayor instantly gives in.
Among the first Supergirl's boyfriends were a human, a green-skinned Coluan, an Atlantean merboy, and, er, her horse. (He was in human form at the time, admittedly, but there was still a kind-of relationship between them after he was turned back; it probably helped that he retained most of his intelligence.)
Pretty much the point of the Barbarella comic strip and carried over, to a lesser extent, in The Movie.
ElfQuest: I'm gonna have to spoiler this whole thing because it involves a major plot revelation. In ancient times Timmain (super-advanced humanoid alien in elf form) shapeshifts into a wolf and mates with the alpha male of a wild pack. result: Timmorn Yellow-Eyes, half-elf, half-wolf and father of the Wolfrider tribe. Many generations later the pure-blooded elf Winnowill views the Wolfriders' origins with disdain, asking the pertinent question: "Do they renew their kinship even now?"
- This disdain is hypocritical since Winnowill is soon revealed to be the mother of Two-Edge, who is half elf/half troll.
- There are also some attempted human/elf pairings, which generally go badly because the elves' "bloodfire" is too intense for humans, although centuries after the main storyline the shapeshifting elf Jink enjoys a number of successful partnerships with humans of both sexes. Since she does seem to have a weakness primarily for telepaths, it may be that the elf/human compatibility issue involves a psychic element...that, or she just has worked out the kinks through experience.
Legion Of Super Heroes: there are a lot of interspecies romances in the Legion; some of the more notable are Brainiac 5(Coluan)/Supergirl (Kryptonian), Colossal Boy (Human)/Yera (Durlan).
The Archie-published Teenage Mutant Ninja Turtles Adventures featured three such relationships. The first two involved mutant turtle Raphael, who became involved with two mutant fox women at different points of his life, and even ended up marrying one of them. On the other hand, there was the relationship between musician Mondo and his girlfriend Candy Fine, which persisted even after Mondo was turned into a mutant gecko.
- Not to be left behind, the original incarnation of the TMNT has featured two different interspecies romances fairly recently. The first occured between Michelangelo and "Seri" (reptilian alien), while the second will occur between Leonardo and human superheroine Radical several years into the series' future.
The comicbook series Firebreather stars the son of a human woman and a Captain Ersatz version of Godzilla who fell in love during one of his rampages.
- Wrong Ersatz. The original concept of Firebreather was for Young Avengers, and he was to be the son of Fin Fang Foom.
- "FIN FANG FOOM! Has been burning with the desire to mate since 1956!
  FIN FANG FOOM! Has absolutely no genitalia whatsoever!
  FIN FANG FOOM! Oh, you cannot ''imagine'' how pissed off he is."
The Star Wars EU comics have their fair share of Interspecies Romance.
- The Rogue Squadron series had a romance between a Calamari and a Quarren: Romeo And Juliet IN SPACE!, in short.
- One of the most prominent romances of the Clone Wars comics was between Jedi Masters Tholme (human) and T'ra Saa (Neti). Neti are extremely long lived, shapeshifting plants.
- At least one of the comics set during the prequels had a fair bit of Ship Tease between the aquatic Kit Fisto and Twi'Lek hottie Ayla Secura. Talk about Naughty Tentacles...
- The downsides in the SW universe tend to be explored a bit more in others, though. For instance, one story features a Gotal who enjoys sleeping with members of other species. Or he did, until he slept with a female from a species that eats the male alive after sex.
- Cade Skywalker (Human) and Deliah Blue (Zeltron) from Star Wars Legacy.
- Zayne Carrick (Human) and Zareal (Arkanian off-shoot) from the KOTOR comics
  - Lucien Dray(Human) and Q'Anila(Miraluka) from the same series.
- If by "their fair share" you mean "so frequently that it's amazing there are still non-hybrids to be found", yes. You would be correct.
A notable storyline in The Avengers had Mantis (human) married to a telepathic alien tree - and since that wasn't squicky enough, in order to mate with her, the tree possessed the dead body of her late boyfriend the Swordsman. Squick accomplished.
Doom Patrol villains, the Brain (a disembodied human brain) and Monsieur Mallah (a genetically altered super intelligent gorilla). For some reason, when comics fans discuss this, they only focus on the fact that they're gay.
- Considering they're a crack pairing from the start, there's really not much else to discuss. Except maybe what poking a brain with THAT feels like.
Echiboo (hamster) and Luna-P (pig) in Aoi House. Pretty much par for the course, actually.
2000AD's Lobster Random ... a mechanophile. That is a (modified) human who is sexually attracted to robots. And not human looking robots either...
Astonishing X-Men: Beast/Brand. Complicated, since he's a human mutant who became more animalistic as he got older and now looks like a giant blue cat, and she looks mostly human and is actually half-alien. Apparently her dad was a huge blue furry thing, which takes it into even more perverted territory.
In the Donald Duck comic "The Old Castle's Secret," the jewel thief Diamond Dick claims that he knew about the hidden McDuck treasure because his "third wife was a McDuck on her great grandfather's side." Diamond Dick is a dog. Apparently something... interesting... has been going on in the McDuck family tree.
The eventual romance and implied sexual relationship between Jimmy Olsen (human, with some plot-related variations) and the Forager (really hot female purple-skinned alien bounty hunter humanoid INSECT) in Countdown To Final Crisis.
Toyed with in Frank Miller's The Dark Knight Strikes Again, where Hal Jordan whose control over his powers now renders him virtually omnipotent, has left Earth and is now living on Mars, where he lives a happy, wholesome family life with his wife and son. Unlike most examples of this trope, the Martians are not rendered physically attractive or appealing in any way; Hal Jordan instead uses his power to make himself a Martian, completely capable of maintaining the form indefinitely, as well as capable of breeding with other Martians, and is extremely reluctant to return to Earth after receiving Batman's transmission, until his wife urges him to help his own people. He only reverts back to his human form after he has already left Mars, and is quick to return as soon as his business on Earth has been finished which involved him multiplying his size to that of many times the Earth, able to grasp the entire planet in his fist, crushing Lex Luthor's planet wide multi-trillion dollar WMD satellite network while leaving the planet itself unharmed.
Aside from the John Stewart example above, the Green Lantern Corps seems rife with this. Hal Jordan and Arisia, Kyle Rayner and Soranik Natu, and when you bear in mind that nearly every member of the Corps is a different species, when relationships between members of the Corps were banned over 200 resigned in protest.
In addition to Brainiac 5 (mentioned above), Supergirl (Kryptonian) had a quasi-romantic friendship with Captain Boomerang (human) and an actual romance with Apokolips native Power Boy. And had a crush on Dick Grayson, but that hardly counts.
Oh, Tank Girl, as if your Heroic Sociopathy weren't enough, you also have to get involved with Booga. The mutant kangaroo. And then cheat on him with your tank... Yeah, it's that sort of comic.
The Spaceknight Rom was in love with the Terran Brandy. On the plus side, Rom is a Galadorian, basically a branch of the human race. On the minus side, he'd been cyborged into an all-covering suit of plandanium armor. On the plus side, it was theoretically possible for him to become a normal man again. Still, whether Rom and Brandy count as an interspecies liaison is a judgement call.

Spuds McKenzie: what a playah! What a dog playah! What a dog playah with human girlfriends... er... right.
The "twist ending" to a recent air-freshener commercial is that the talking elephant housewife's husband is a many-stinky-shoed centipede.

Bicentennial Man: Andrew (robot) and Portia (human).
- Although by the end of the film they're on more-or-less equal ground: Him, a mostly-human-robot, her, a mostly-robotic-human.
A Bugs Life: Manny, a preying mantis, is married to a gypsy moth named Gypsy — a wise choice when you keep in mind what would happen if he hooked up with a female of his own species.
Chapters 10-13 of Coga Suro have Hades [an android] pursuing Rachel [human].
Cool World: "'Noids do not have sex with Doodles." But Hollie Would if Hollie Could... and Hollie Does.
A subversion from Earth Girls Are Easy: as the alien Mac calmly takes off his clothes, preparing to have the human Valerie, she keeps rambling on, trying half-heartedly to talk herself out of doing it. At one point she says "Maybe we're not even compatible..." (glances over...) "...OK, we're compatible.."
The hippo/crocodile romance in Fantasia.
In Galaxy Quest, human Fred Kwan hooks up with tentacled alien Laliari. This causes a major Squick moment for Plucky Comic Relief Guy Fleegman.
Guy: Oh, that's not right!
Though no interspecies couples appear in either Ice Age movie, Ellie is quicker to conclude that Manny is "part possum" than that she is not a possum at all. Manny is bemused and Crash and Eddy are dismissive ("You wish [you were part possum]"), but no real indication is made that such a thing is unheard of.
- It's also interesting that when Eddy worries that they'll have to repopulate the Earth, Crash points out that if their group makes up the last of the living creatures, "everyone left is either a dude or [their] sister." No mention is made of the various species that make up the small group.
Also from the Ice Age films, Scrat and Scratte, although superficially similar, probably aren't of the same species: she's a flying squirrel and he's not (and is surprised to discover she is one). Possibly the writers Did Not Do The Research and didn't know that flying and non-flying squirrels are only distantly related.
Definitely present, albeit unconsummated and one-sided, in King Kong. Peter Jackson's remake made it more of a mutual platonic crush on both sides.
Shrek starts out with Shrek and Fiona as ogre and human, and even after she becomes an ogre, too, we've still got a donkey/dragon romance, complete with mutant babies!
A certain amount of fanon speculates that, despite appearing to be the same species, Anakin Skywalker and Padme Amidala weren't, and that Padme aged much more slowly than Anakin did. That's what happens when you swap the ten year old kid for a guy a year older than the actress and try to pass him off as being the same person.
- To be fair though, a nine-year-old kid would change a LOT more in ten years than a fourteen-year-old girl would.
- The Star Wars Expanded Universe includes numerous species that are classified as "Near Human". Which basically means by the proper definition of the word, they're not really separate species at all, just humans with minor visual differences (and occasionally a bit more, like the Miraluka, who have no eyes and see through the Force). Given the vast amount of time covered in the EU, it's likely that all the "Near Humans" were descended from regular humans at some point in the distant past. On the other hand, the EU also includes a few romances between humans and distinctly non-human aliens, where it's made clear that they're not capable of reproducing at all.
- Hell, they even have SPACE ELVES now! Is Lucas totally cribbing from Warhammer lately or what?
Tank Girl — Human/Mutant-kangaroo-that-was-formerly-a-dog
Who Framed Roger Rabbit: Roger and Jessica, who is a Rabbit by marriage only.
- Also, it's pretty clear that Eddie Valiant wasn't expecting her to literally be playing patty-cake with Mr. Acme. Does human/toon romance count as this trope if the toon is human(oid)?
In District 9, the government issues the false story that Wikus had sex with a Prawn as a way of explaining his Body Horror.
- Inter-species prostitution also occurs.
In Bolt. Thanks to a Relationship Writing Fumble, it can appear that Bolt and Mittens' relationship is this.
City of Angels has Seth (angel), and Maggie (human). It doesn't end well.
Men In Black II hinted at this between Kay (Tommy Lee Jones) and an alien princess sometime in the past. Jay fell hard for a woman who also turned out to be a Human Alien, although she left Earth before it got very far.
A rather painful aversion in Disney's The Sword in the Stone: Wart (Arthur) gets turned into a squirrel temporarily by Merlin's magic, and a big-eyed girl squirrel falls for him, instantly turning into a Stalker With A Crush. Though annoying, she is terribly upset when Wart turns back into a human, and he apologizes, "If you could only understand," while she, not comprehending a word, runs away and cries. The scene fades with the poor squirrel sobbing her little rodent heart out, which seems to be the (for kids!) movie's only commentary on romantic relationships.
The core plotline of James Cameron's Avatar (aka Dances With Wolves In Space), with a human manipulating a half-human, half-alien body (the title avatar) falls for an alien woman.
Everything You Always Wanted to Know About Sex (But Were Afraid To Ask) had a romance between Gene Wilder and a sheep.

Piers Anthony seems rather fond of this trope.
- Particularly Squick-inducing pairings are hinted at but not shown explicitly in Xanth, where any two creatures of opposite gender who drink at a "love spring" will fall in lust and (successfully) interbreed. This is the origin of most of the sentient species in the series including harpies (human/vulture), centaurs, etc. We also have a story where an ogre/human hybrid falls in love with a human/nymph crossbreed, the child of a centaur/hippogryph (eagle/horse hybrid) and all manner of others.
- In Xanth, EVERYTHING is intelligent (at least to some degree), though not everything can communicate in the human tongue.
- In his Apprentice Adept novels, we are "treated" to human/unicorn (the unicorns can shapeshift to human), human/robot, human/werewolf, human/vampire, and human/alien relationships, just to name a few.
  - To say nothing of robot/alien, vampire/troll, and other combos with no human participants.
- Incarnations of Immortality series: human/ghost, human/demoness (three times, one rather squicky), human/damned soul. Zane/Luna is an aversion, as they're both human (though he's the current Death).
Girl falls in love with robot is a key element in Isaac Asimov's Robots of Dawn.
Philip José Farmer was famous for writing one of the first erotic stories between a human and an alien in The Lovers... If you can really call that "erotic."
Alan Dean Foster's books.
- Quozl is about cute rabbit-like aliens who eventually integrate into human society, and believe in frequent sex anytime, anywhere with any compatible intelligent species as a legitimate means of blowing off steam. The book establishes that once Humanity understood that social more, the Quozl quickly become very popular company.
- Spellsinger is set in a world where humans and anthropomorphic animals live side by side including romantic and sexual encounters.
  - Subverted in that, while the Earth-import protagonist feels attracted to an ermine stripper, he's dismayed by his own feelings and never actually goes native enough to join in this trope's fun.
- The Humanx Commonwealth series features a wide variety of alien species. Most of the time the biological and social incompatibilities are treated seriously, although mental compatibility between some humans and the insectoid Thranx occasionally reaches Ho Yay proportions. There are some memorable scenes in Bloodhype, however, where a particularly flirty character discusses ways to erotically stimulate members of other species, intentionally and quite successfully Squicking out her companions. Better Than It Sounds.
  - In Sliding Scales a reptilian AA'nn falls in love with the protagonist Flinx. She doesn't confess her love until already mortally wounded and dies in his arms, prompting one of many incredible Unstoppable Rages and discovering a new Limit Break technique, more or less a literal application of the Death Glare.
Played in an unusual fashion in The Dark Tower, where Roland has sex with a succubus in order to get information from it. In a later novel, the same succubus, now in male form, rapes Susannah and impregnates her with Roland's sperm. When the resulting child is born, it's a cannibalistic human-spider hybrid. This is exactly how medieval folklore said succubi/incubi worked. That a demon could never create true sperm or truly mate with a human, so demon children were the result of a succubus stealing a man's seed, turning into an incubus and raping a woman. Succubi/incubi themselves have no "real" gender, being spirits.
- Also, Rhea and her snake...
Mercedes Lackey's The Eagle and the Nightingale, with human/birdman relations (along with, "Oh, yeah, people do this all the time back home.").
- The Fire Rose deals with the romance between a human and an involuntarily transformed sorcerer anthro wolf.
- Plus the obligatory human / Cat Girl pairing in her Mage Winds series, although said Cat Girl is technically a transformed human (with a magically augmented libido). Considering her father was an insane mage lord inhabiting the body of a descendant who used her as a sex slave to raise magical power, isolated her from friendship, tortured her to keep her in line, and tested all of his magical body alterations on her before applying them to himself, she's well removed from the traditional role of the Cat Girl, although she does play the Mad Scientists Beautiful Daughter to the hilt.
  - "Well removed?" She's a Deconstruction of Ms Fanservice; that's not "well removed." She's still the sex kitten of the group.
  - In the same series, Lavan Firestorm and his ~~horse~~ Companion.
- The Chrome Circle has a half-dragon, half-kitsune vixen fall in love with a human mage. In a slight subversion, the relationship between them (and the vixen's parents) are...rocky, at best.
The Silver Metal Lover, by Tanith Lee, and its sequel, Metallic Love, in which, you guessed it, girl falls in love with robot.
Fritz Leiber's novel Wanderer included romance with an off-world female from a feline race. Think serious scratches down the back. Leiber's Fafhrd And The Gray Mouser have non-human girlfriends among their conquests, including a ghoul and a sapient rat-girl.
Deconstructed in several HP Lovecraft stories that show how squicky such a thing would actually be - eg. Facts Concerning the Late Arthur Jermyn and His Family and The Shadow over Innsmouth. On the other hand, considering Lovecraft's peculiar attitude towards intraspecies miscegenation, they could also be seen as not so much a Deconstruction but just a different brand of Fantastic Racism allegory... Let's face it: the guy was squicked out when he discovered that his great, great grandmother was Welsh.
- In a way, this could be seen as a real-life deconstruction of Squick itself.
Perdido Street Station by China Mieville: The main character's lover is an insect-woman.
- Admittedly, she does just have a big insect in place of a head; everything else is human.
Sometimes you get interspecies sex without the romance, e.g. Rishathra in Larry Niven's Ringworld series (it's a bonding/peace ritual between hominid species).
- Averted with species that are too different, however. The marooned kzinti Chmeee eventually had to invade the Map of Kzin in order to score.
- Niven also discusses interspecies sex in the short story "Shall We Indulge in Rishathra?", found (along with the Superman essay, mentioned above) in the short story collection N-Space.
- The Draco Tavern series contributes to the subject in the short story "Breeding Maze". Arguably, another story from that setting, "Smut Talk", also counts, as it explores the possibility of a sexually transmitted Alien Invasion.
Eragon falls madly in love with Arya, an elven ambassador. Lots of Love Hurts ensue.
Carrot and Angua of Discworld (~~human~~ conspicuously tall and clean-shaven dwarf [by adoption]/werewolf). And don't forget Angua's implied past relationship in the The Fifth Elephant with an ordinary, albeit extremely clever wolf. She's also been hit on (albeit unsuccessfully) by dogs, including Gaspode the Wonder Dog and Mr. Fusspot. The possibility of their children is something of a plot point in Feet Of Clay.
- Lupine and Ludmilla Cake: While they're more-or-less the same thing (werewolves), one's a wolf who turns into a wolf-man during the full moon, and the other is a human that turns into a wolf-woman (they more or less meet in the middle). Somehow, they make the relationship work, despite only having one week-in-four per month in which they are the same bodyshape. The secret and beloved dark heart of this meme is that that's very much their affair, and none of our business... or to put it another way, maybe they are happier than you think.
Many of the girls of Harry Potter were quite taken with Firenze the Centaur. Hagrid's father also apparently produced a child (namely Hagrid) with a female giant, and Flitwick has a goblin among his ancestors, but since these are kid-friendly novels none of these scenarios actually occur on "camera".
- However, during the books, there are at least 2 major instances of interspecies marriage (with children produced as well): Lupin and Tonks (werewolf/human) and Bill and Fleur (part-werewolf/part-veela). Though it is open to argument whether HP-verse werewolves can be categorized as a non-human species, rather than as humans with a medical condition.
Teased in The Demon Awakens, the first of RA Salvatore's novels set in his own world of Corona. A centaur comments that he'd only let a woman ride him - and only if he got a ride himself afterwards.
Subverted slightly in Wild Cards wherein there was a human/centaur sexual relationship. The subversion comes from the fact that Finn the Centaur was once entirely human, but the Wild Card virus turned him into a centaur.
- Brain Trust/Tachyon [human/Takisian], plus Tachyon also had many other relationships with human women, including one which resulted in Half Human Hybrid child (mentioned as deceased) and grandchild. Popinjay also had a Takisian wife. Then again, Takisians are essentially human.
Several interspecies romances factor into Michael A Stackpole's and Aaron Allston's Rogue Squadron and Wraith Squadron series, respectively, in the Star Wars Expanded Universe. The most prominent are Gavin (Human) and Asyr (Bothan), who catch quite a lot of flak for their romance, what with them being war heroes and all. Interestingly, it's the Bothan who catches most of this—even though a prominent Bothan politician notes to her that xenophilia isn't unknown among Bothans. It's just that she wants to stay together long term and adopt children - the parts match up, but they can't reproduce.
- One of the more memorable examples, played for laughs and occurring off-screen in the past, was the romance between Corran Horn (Human) and a ferret-like Selonian. A quirk of Corran's bio-chemistry made his sweat acidic enough to penetrate the waterproof fur of his Selonian lover and irritate her skin, while her fur had a similar effect on his own; they effectively sunburned each other whenever they touched. Corran also brings up the point that dating outside of your species can be problematic in other ways - what if your partner is used to giving and receiving love bites? With ten-centimeter teeth? Though thankfully there's no indication that he has personal experience in that particular area.
- The Wraith Squadron books had a fair share of this, too, with two of the squadron members - one Human, one Twi'lek (the woman, naturally) - getting together. For that matter, the Expanded Universe has Twi'lek females as being the desired partner of virtually any near-Human species.
  - Well, when they look like this◊, can you really blame them?
  - A Togruta is fine too!
  - It might help when they dress that way◊.
  - In the Rogue Squadron books, there's also a male Twi'lek, Nawar'aven, hooking up with a female human. Also among the Wraiths, the team plays a prank and allows the residents of a seedy bar to think that Piggy (the male Gammorrean, who looks like exactly what you'd expect from the name) and Falynn, a human female, are a couple. They're not, and Piggy gently takes her to task for being embarrassed about being seen with him.
- Shadows Of The Empire also had Xizor seduce Leia. Xizor is a Falleen, a suspiciously mammalian-looking "reptilian" species (EU sources have since retconned them to be "reptomammals") whose members can (and do) produce pheromones that can ensnare a good chunk of the sentient species in the Galaxy.
- Between the publication of The Thrawn Trilogy (Winter's first appearance) and the X Wing Series (her eventual husband Tycho's introduction), a few Star Wars Expanded Universe novels hinted at White Haired Pretty Girl Winter Celchu and Admiral Ackbar being an item. Yeah.
- Star Wars literature in general tends to have a fair amount of Interspecies Romance, and sometimes between rather disturbing couples. One example would be Dice Ibegon and Lak Sivrak, a female Florn Lamproid and a male Shistavanen. The latter looks like a Wolf Man... the former? A snake-like body, six clawed legs, a poisonous sting in the tail, and four long, curving fangs forming a ring around their circular mouth. And the two were explicitly stated to be physically compatible and very much attracted to each other...
Piro and Ibronka in the Viscount of Adrilankha. Granted, this one is less obvious due to the characters being of different clans of the same race which were manipulated by extradimensional aliens millions of years in the past to be almost the same but have a few traits resembling the native wildlife of the world instead of actual different species, but the severity of the cultural taboos make this count.
- Don't forget Zerika and Laszlo, who are Dragaeran and Easterner, respectively.
Being based on a Dungeons And Dragons world (see below), there was a surprising amount of angst from Driz'zt about his eventual romance with Catti-brie - though admittedly only part of that was due to race. It's done with now, and they're married, though Salvatore has said he's not gonna give them kids.
- It might have had something to do with the fact that he knew her when she was ten years old...and that he's pushing eighty but would live for centuries (barring accident, violence, or disease).
- The angst was also partially, at least at first, about the part where Cattie-Brie was the love interest of Drizzt's best student Wulfgar before he had a ~~bridge~~ cavern dropped on him when Drizzt became more popular.
- Contrast him with Jarlaxle, the charmingly evil dark elf rogue, who can and will sleep with anything with two legs, a pulse, and the ability to consent (which is what makes him charmingly evil, not just evil). And maybe female sexual organs. He and Drizzt both are noted to be unusual among drow males, who are culturally xenophobic. (Females will sleep with anything, including demons, in the pursuit of power, though there's probably no romance. For that matter, intraracial relations in traditional/Llothian Drow society are rarely all that romantic.)
  - There's a reason behind the old joke "How the Drow do it? He lies on his back, she stabs him with a dagger, as a sacrifice to Lloth".
  - Then again, Forgotten Realms got Crinti (aka "Shadow Amazons"), descendants of southern drow, humans, and half- (surface) elves who looks accordingly and got strong drow cultural influences. The people numerous and strong enough to raid every once in a while Halruaa, of all places.
Happens in the Animorphs series with two of the main characters, one of whom is a human stuck in the body of a hawk (he regains the ability to temporarily turn back into a human.
- At least one of the books directly addresses the ambivalence both characters feel about the relationship, including with issues such as Tobias's much shorter lifespan if he stays as a hawk.
- Also present in the companion books The Andalite Chronicles (Andalite/human) and The Hork-Bajir Chronicles (Andalite/Hork-Bajir. Less squicky than usual due to the Voluntary Shapeshifting technology that allowed them to become members of the same species, permanently, by the end of both books.
Averted in Goddess by Mistake, a light fantasy novel wherein the heroine finds herself in an arranged marriage to a centaur (who takes human shape for the actual coupling).
Miles Vorkosigan's on-again/off-again relationship with Taura should count (despite the Absent Aliens setting in the Barrayar Books, she is at least as far from Human as a Drow is). Leo Graf's and Bel Thorne's respective marriages into Quaddie society also apply.
In Holly Black's Valiant, Val, a human, is in love with Ravus, a troll.
- Whose own father was a human, although apparently troll blood always breeds true.
Magician: Tomas and Aglaranna (human / elf), plus Nakor and the Dark Queen (she's human, but it's strongly implied that he's not).
- Tomas was somewhat mutated by being possessed by the Valheru Ashen-Shugar, a survivor of the race who used to own the elves. He stated that his lifespan had been extended to a thousand years.
Neil Gaiman's Stardust: Tristran and Yvaine (half-faerie half-human / star, ya rly)
- Also Tristran's parents, Una and Dunstan (faerie / human), obviously. And a side mention of an ordinary cat being knocked up by a faerie cat, producing a smoky blue kitten with color-changing eyes. The other kittens in the same litter were normal, but cats can have kittens by multiple fathers in the same litter.
Robert Silverberg's short story Ishmael In Love is told from the perspective of a dolphin in love with his (human) trainer.
The product of Nira and Jora'h's interspecies romance (and her half-siblings, some of whom are also her cousins, born of the interspecies rape of Nira by Jora'h's brother among others) save the galaxy in Kevin J Anderson's Saga of Seven Suns.
Interspecies romance was fairly common and accepted in Alien Nation, although the Tenctonese tended to be fairly rough in sex so had to visit clinics to make sure they took it easy on their human partners. No children were produced, but a deformed Tectonese girl produced from an experiment was mistaken for being half-human for a while due to her single heart and other weaknesses.
Spider Robinson handles interspecies romance quite logically in The Blacksmith's Tale in his Callahan's Place series.
Mickey Finn (A 6'11'' tall, 600 pound robot/cyborg alien) "You do not even know if we are sexually compatible—"
Mary Callahan (Human) "The hell I don't. I can see fingers and a tongue from here; anything else is gravy."
The Firekeeper series presents us with the namesake heroine, Firekeeper, and Blind Seer, a Royal Wolf (bigger than most and possessing a sentient mind). Firekeeper wrestles with these feelings for a while but seems to come to terms with them by the end of the sixth book.
Commander Bradshaw of the Thursday Next books is married to Melanie, who's a quite nice woman with conservative taste in dresses, and who also happens to be a six-foot-something gorilla. Bradshaw is rather sensitive about the topic.
- In the Nursery Crime books by the same author, Ashley, an alien member of the force (who at one point mentions that the type of earth creature his species most resembles are several jellyfish stuffed inside a balloon too small for them) becomes quite taken with Mary, and even manages to take her out on a date that she tries fairly hard to avoid. The end result is oddly sweet.
There's a lot of this in the Twilight books, especially concerning Bella.
Many of Tom Holt's books feature a character who is really a type of magical being shapeshifted into human form, who fancies a certain human. In Nothing But Blue Skies, the protagonist is a female dragon disguised as a human, who develops a crush on a young human man. The Paul Carpenter series features a she-goblin who shapeshifts into a different beautiful human girl every day and tries to hit on the main character. She mentions that lots of goblin girls like to have flings with humans, and that as shapeshifters, they are open-minded and don't care much about appearances.
Elves and humans in Middle-earth have intermarried ~~a few~~ several times (Beren and Lúthien, Idril and Tuor, Aragorn and Arwen). Lúthien herself was only half-elven; her mother was a Maia. Note that Aragorn and Arwen are both descended from both Beren and Lúthien and Idril and Tuor.
- Fandom also has a tendency to pair off Éowyn (human) with Merry (Hobbit). Even though they're both married to people of their own species.
- There's also Tom Bombadil, an ambiguous "eldest" and Goldberry, a river nymph. Doesn't really matter for the story, though.
  - If you unravel Bombadil's allusions, you can conclude that both Bombadil and Goldberry are Maia, and therefore only any one gender out of habit anyway
Two words: Lisanne Norman.
Happens in Amelia Atwater-Rhodes' novels, particularly in Hawksong the first novel of her Kiesha'ra series. To prevent war, an Avian (bird shapeshifter) princess and a Serpiente (snake) prince consent to a political marriage to end their generations-long war, but find themselves falling in love. Their child, a half breed wyvern who represents both her parents' shapeshifting powers, in turn chooses neither an avian nor a serpiente mate, but a wolf woman. This is a good thing as choosing any male mate would lead to her combined powers manifesting very strongly and dangerously in any child she bears.
- In her modern day, Nyeusigrube books there are several interspecies romances between vampires, shapeshifters, humans, and sometimes witches, but none are so unusual as Shevaun and Adjila. Shevaun is a vampire and Adjila is a Triste, a particular kind of witch whose blood is almost always poisonous to a vampire. The two species are usually sworn enemies to a point that Triste can be a synonym for vampire hunter. They have been partners for centuries.
The main characters in The Owl and the Pussycat. (And in the incomplete, post-posthumously published sequel, they have kids. But this is Edward Lear.)
The Dresden Files has a Werewolf/Wolfwere pairing and a human/vampire pairing. A couple was split up when it became a wizard/vampire pair.
Artemis Fowl plays with this trope in Book 6, when Holly and Artemis kiss and start developing romantic feelings for each other. This is subverted, however, when Holly discovers that Artemis has manipulated her.
- Subverted? Really? She's already starting to forgive him within a chapter or two especially after he gives her a chance to say goodbye to her dead mentor, and despite some lingering resentment on her part by the end they're both clearly interested in one another, and still closer to an actual relationship than at any point up to their adventures in time-travel-augmented pubescent hormones.
The Legend of Little Fur has this as a constant mystery until A Riddle of Green- Little Fur is half elf, half troll. Everyone wonders how an elf and a troll could love each other enough to have a child. The answer: since Little Fur was going to save the world, a she-wizard captured an elf and a troll and kept them locked up together until they loved each other enough, and then she released them once Little Fur's mother was pregnant.
In Diane Duane's The Tale of the Five series, the first human protagonist gets involved with a fire elemental, while the second takes up with a dragon. Sex definitely does happen, though it tends to be a complicated sort of out-of-body experience.
In the Courts of the Crimson Kings, by S.M. Stirling. After he saves her life, Martian Action Girl Teyud matter-of-a-factly takes Adventurer Archaeologist Jeremy off to her cabin. His human co-worker looks ready to protest (to which Jeremy responds with a big grin and The Bird) but doesn't say anything till afterwards; her main objection being that a bust-up between the two — likely given the cultural differences between Earth and Mars — might endanger their mission.
Nobody has mentioned Trillian and Zaphod yet?
In the Codex Alera, main character Tavi has tense partnership-turned friendship-turned romance with Proud Warrior Race Girl Kitai. He's human, she's a Marat (basically human, but with enough differences to qualify as a seperate species- white hair, abnormally high body temperature, excellent night vision, and the ability to bond telepathically with animals being chief among them).
In Elizabeth Kerner's Song in the Silence series, we have Lanen (human) end up with Ahkor/Varien (dragon). This is facilitated by divine intervention, as Ahkor is changed into human form after he is grievously wounded in the first book. It becomes a plot point later on when Lanen ends up pregnant. While Varien's shape is human, his blood is apparently not, and the mixture of the two in the kids is slowly killing Lanen before they get some mages to fix it. Later on both Varien and the kids get the ability to shapeshift between forms at will.
Metaplanetary by Tony Daniels (not to be confused with Metaplanetary by S. P. Meeks) pairs a human with an "emancipated" software program. Their kids exist partially in the "real" world and partially in cyberspace simultaneously, and it's mentioned offhandedly that their baby talk was white noise. (There's a Handwave about radiation—just go with it.) The intelligent ferret also has a powerful sex drive, which turns towards humans when her original body dies and she winds up Sharing A Body with an Artificial Human, but she's after Anything That Moves, in a rather blunt fashion. (Yes, this book is weird.)
Played straight and taken seriously In Ann C. Crispin's Voices of Chaos, where the human female and cat-alien male leads end up in a romantic (and sexual) relationship. Really, considering that it's set in a series whose premise is fostering interspecies understanding and universal goodwill among a cooperative league of friendly alien nations, the only surprise is that it took until the sixth book to do it.
In the Mercy Thompson novels, werewolf males typically marry human females. This is because few women opt to become werewolves (or survive the process of becoming one), and because female werewolves in this series are sterile, making them unsuitable mates for males who want to be fathers. Mercy herself (a coyote shapeshifter) was once courted by a werewolf, who'd sought a fertile mate with similar powers.
- Mercy herself is the product of a one-night stand between her human mother and a Native American coyote shapeshifter.

Babylon 5. Sheridan/Delenn (human/Minbari-Human Hybrid), Lumati/alien business partners (Lumati/aliens of a different species that they make deals with, because sex is the Lumati handshake), G'Kar/multiple prostitutes (Narn/Humans/Centauri/God-only-knows-what-else), porn-star/Pak'mara porn-star (please don't make us spell it out).
- That last one is actually an in-universe example of Did Not Do The Research and You Fail Pak'Mara Biology Forever.
- In the Pilot Movie of Babylon 5, Commander Sinclair cautions a human male with his eye on a hot-looking alien to "stick to the list." The guy accuses Sinclair of being a bigot, but it turns out that alien's species is akin to the praying mantis—"After they finish, they eat their mate."
- And, of course, we must ponder the very existence of a "list".
  - Not to mention the Squicky encounters that got other aliens taken off the list!
Joss Whedon examples:
- Buffy and Angel, Buffy and Spike: human/vampire.
- Cordelia and Angel: "augmented human"/vampire.
- Cordelia and Connor: different type "augmented human".
- Cordelia and Doyle, Xander and Anya: human/human-demon hybrid.
- Cordelia and Groosalugg (I'm sensing a trend): "augmented human"/human-looking demon.
- Darla and Angel: human/vampire, for a very short time in season two.
- Willow and Oz: human (witch)/werewolf.
- Buffy and the Immortal (false rumor started by Andrew): human/sort-of-demon-ish guy...thing?.
- The Immortal and Darla and Drusilla: demon/vampire/vampire.
- Jasmine in Cordelia's body and The Beast: higher power/demon.
- Angel and Nina: vampire/werewolf.
- Marcus Hamilton/Harmony: demon/vampire
- As of Season Eight- Willow/Saga: witch/snakewoman.
- And also Dawn and Kenny: human (technically)/thricewise (which seems to be some sort of demon). Yeah, check out the Jo Chen cover for issue 25 to meet all your daily Squick requirements. There are tentacles.
Farscape: D'Argo gets a lot of this. A Luxan, he was married (and had a child with) a Sebacean (human-offshoot); had a long-running romance with Chiana (a Gray Skinned Space Babe); thought about Jool (an Interion); and admitted planning on "approaching" Zhaan (human-looking plant) in one episode. And this doesn't begin to cover innuendo with random denizens of Adventure Planets.
- Then there was John Crichton's brief pairing with Zhaan. It's debatable if this applies to his relationships with Aeryn Sun or Gilina Renaez, considering how closely related Humans and Sebaceans are, Sebaceans being a sub-race of Humans, genetically altered by the Eidelons.
- And all of this in a verse where cross species breeding is possible and illegal.
Captain Jack and the insect woman Chantho in the Utopia episode of the most recent Doctor Who. That actually went nowhere, though, because she was already in love with Sir Derek Jacobi. Heck, Captain Jack and other people from his time period (the 51st Century) embody this trope.
- Not to mention anyone falling for the Doctor, though he's a Human Alien (at least externally.)
- Astrid and Bannakaffalatta from "Voyage of the Damned" count for this trope, too.
- And Branningan (cat person) and his human wife, Valerie, in "Gridlock".
- The fourth series also gives us Lady Eddison and her long ago love affair with a giant senient wasp in "The Unicorn and the Wasp". Though he did have a human form.
- Ahem. The Doctor and Rose (and whoever else has a crush on him).
- The Doctor states that this sort of thing becomes quite common in the future, when humans have contact with many alien species. He implies that Captain Jack's versatility is actually the norm.
- And then there the Master and Lucy Saxon, his wife. Time Lord/Human
Torchwood's Tosh and "Mary" (in "Greeks Bearing Gifts.")
Battlestar Galactica has
- Baltar and the "Six" in his head (human and angel)
- Caprica Six and the "Baltar" in her head (Cylon and angel)
- Helo and Athena (human and Cylon)
- Cally and Tyrol (human and Cylon)
- Starbuck and Anders (human/angel and Cylon)
- Leoben (Cylon) is a Stalker With A Crush for Starbuck (human/angel)
- Cain and Gina Six (human and Cylon)
- And to save space, Baltar (human) has been with the following Cylons: Caprica Six, Gina Six, D'Anna, Tory, and Lida Six.
- Boomer and Tyrol seemed to be one at first, but then Tyrol proved to be a Tomato In The Mirror, making it a Same Species Romance between two Cylons.
Kirk and every Space Babe, Green Skinned or otherwise, ever. As a rule, Star Trek doesn't even blink over interspecies sex. Case in point, Mr. Spock's parents, the Vulcan Sarek and the Human Amanda are never depicted as anything but happily married.
- Subsequent Star Trek series include several notable hybrid characters, including Deanna Troi (Human/Betazoid); K'Ehleyr (Human/Klingon), who herself had a child with a Klingon; Ba'el (Klingon/Romulan); Sela (Human/Romulan) in Star Trek The Next Generation; Ziyal (Bajoran/Cardassian) in Star Trek Deep Space Nine; and B'Elanna Tores (Human/Klingon) in 'Star Trek Voyager''.
- In Requiem for Methusaleh, Kirk falls in love with a woman who turns out to be an android, but it does not change his feelings.
- Spock himself and Leila Kalomi (This Side of Paradise). He is forced by the spores into confronting his human feelings and tells her "I do love you".
- Spock also fell in love and had a sexual relationship with another non-Vulcan woman, in All Our Yesterdays. In addition, a number of human or at least non-Vulcan women showed an interest in Spock at some point, including Nurse Chapel (desperately in love with him), Lt. Uhura (flirted with him in a couple of episodes) and Droxine, a human-looking princess from an alien planet in the episode Cloud Minders. Not to mention his relationship with the Romulan Commander The Enterprise Incident), although Vulcans and Romulans are an offshot of the same species (and a fairly recent offshoot at that, especially given how long both species live), so that might not count.
- Furthermore, in the 2009 film, young Spock has a romantic relationship with Uhura in the alternate timeline while Kirk, unsurprisingly, has a fling with Gaila, a green-skinned cadet from Orion.
- In Star Trek The Next Generation, Tasha Yar had a one-night stand with a "fully-functional" android, Data.
- In the Star Trek Deep Space Nine episode "You are Cordially Invited,", Martok's wife has some serious reservations about Worf marrying a non-Klingon. Also, in another episode a Klingon gets in an uproar about his sister marrying a Ferengi (albeit for political reasons); there is some mild attraction between them, but they get a divorce, then later have one last fling.
- Quark and a Cardassian woman.
- Star Trek Deep Space Nine featured several interspecies romances and even marriages between the main and recurring characters: Jadzia Dax and Worf (Joined Trill/Klingon), Kira Nerys and Odo (Bajoran/Changeling), Rom and Leeta (Ferengi and Bajoran), Ezri Dax and Bashir (Joined Trill/Human) and a recurring mixed species character Ziyal, the daughter of the Cardassian baddie Dukat and one of his Bajoran mistresses.
- B'Elanna Torres on Star Trek Voyager often comments that her childhood was not a happy one, because her father "Couldn't handle living with one Klingon, let alone two".
- To really put the cherry on top, Cryptic Studios is advertising their extensive character creation process as "creating your own unique species," complete with optional origins story a la City of Heroes and Champions Online. Given that Cryptic is advertising to Trekkers on one hand and your typical MMO nerd (which inevitably includes the average 4channer) on the other, expect this trope to boldy go where no trope has gone before.
Star Trek Enterprise, where humans had only been in contact with extraterrestrials for less than a century and sometimes still get squicked over the idea of romancing them. But this didn't stop Reed and Trip from being distracted in the first episode by a pair of alien dancing girls, and no less than three human crewmembers (Reed, Archer, and finally Trip for the win) from drooling over T'Pol at some point or another. Justified, as A: Vulcans are ridiculously human, and B: Jolene Blalock tends to have that effect on people.
- It is also hinted in Enterprise that even farther in the future, the 30th century, interspecies relations probably became very commonplace. The time traveler Daniels mentions that he is "human, more or less" implying that he may have some alien blood in him.
  - The body of another time traveler whose trip didn't go so well was also examined and found to be a hybrid of numerous species, including human, Vulcan, and I can't remember what else.
- The episode "Dear Doctor" had a female human (Crewman Cutler) getting interested in Denobulan doctor Phlox. Whether his sixteen-inch tongue is part of the appeal was not mentioned, but the good doctor did caution her on the cultural differences of his species (Denobulan males are somewhat inhibited, but on the other hand have polygamous marriages – Phlox has three wives who each have two other husbands). Likewise Trip is squicked out when one of Phlox's wives puts the moves on him and Phlox is excited rather than annoyed.
- Riker on Star Trek The Next Generation never seems to be interested in any female unless she is extraterrestrial, and apparently is irresistible to all of them. Plus to ~~a hermaphrodite~~ an asexual in one Anvilicious Very Special Episode. Good thing the show ended before he got around to the Horta; that acid's a bitch to clean off.
- Star Trek Voyager. The perils of this are explored in "The Disease" when Harry Kim has a passionate affair with an alien woman without checking with his doctor first. No, he doesn't get an alien STD – the disease is love. Unfortunately the attraction is not only emotional but biological as well. Plus Harry's skin tends to glow, which must make sex in the dark easier but seriously squicks his friends. Harry should have known better though. In "Favorite Son" a race of sexy space vampires try to suck out all his DNA – as they have few males it's the only way they get enough genetic material to continue their species. And Q is constantly pursuing Janeway, but while he promises that foreplay with a Q can last for decades it appears the actual act only lasts a second to the outside observer ("The Q and the Grey").
- For a more literary reference, the series Star Trek New Frontier manages to get no less than THREE cross-breed offspring on the same ship - a Vulcan/Romulan (not improbable, as the Romulans and Vulcans are related races who split only two thousand years ago), a Vulcan/Hermat, (where a Hermat is a hermaphroditic and rather sexually liberal race), and a Hermat/Human (actually not, as the Hermat was playing a practical joke on the human). It should be noted that there is only ONE Hermat in the crew. There was also the potential for a Vulcan/Xenexian cross, but it did not come about. A Human/Xenexian relationship (or rather several), a Human/Thallonian, and a Xenexian/Thallonian did indeed occur though. And some that were probably forgotten.
- Of course, whether the Vulcan/Romulan example is a proper example of this trope, given that they are at least as genetically close as the Sebacean example in Farscape, if not more, is somewhat debatable...
- Star Trek's philosophical attitude towards interspecies relations meant that Beverly Crusher's tragic romance with the joined Trill Odan came rather out of left field; she couldn't deal with the host changing bodies so frequently, no matter how much she loved him.
  - Retroactively justified, as changing hosts does tend to change the personality of the bonded Trill, making for an unstable relationship at best. But we don't learn that until years after the Odan story.
Tokusou Sentai Dekaranger has Doggie Cruger, an anthropomorphic dog, who has feelings for his subordinate, the half-human half-swan person Swan Shiratori (whose own parents must have fit this trope). This plot element wasn't retained when Dekaranger was adapted into Power Rangers SPD and Cruger's counterpart was married to a new character of his own species (though there are a few hints that Swan's counterpart Kat does have feelings for Kruger).
- The next series, Magiranger, has the Rangers as Half Human Hybrids, part human and part Sky Saint/Heavenly Saint. This is underplayed, though. Also, Urara winds up paired with another Saint, Hikaru.
Magiranger's Power Rangers counterpart, Power Rangers Mystic Force, has several interspecies Last Minute Hookups, such as Leelee and Phineas (Vampire (or at least born from a vampire if not one herself) and troll/goblin hybrid), Toby and Necrolai (human and (ex-?)vampire), Madison and Nick (human and Human Alien from mystic dimension), with a little subtext between Daggeron and Itassis (mystic Human Alien and the highest-ranking demon now that the Big Bad is gone) for flavor.
- It was present as early as Power Rangers Zeo, when Billy chose to stay on Aquitar because he had fallen in love with a colleague who'd helped him find a cure for his aging disease. Notable in that she was amphibious, and he was actively chosing to live long-term on a planet where most all life goes on underwater. Billy, despite being a blue ranger, does not breathe water. Hey, Love Makes You Crazy.
Mork And Mindy.
The Muppet Show has Kermit the Frog and Miss Piggy.
- Also, Gonzo, whose species was unknown at the time but is now said to be some kind of alien has an attraction to birds, especially chickens, and in one case, a cow.
- And in the cartoon spin-off, Muppet Babies, he's in love with Piggy. Camilla, is, alas, just a stuffed toy in that version.
- The Muppets Take Manhattan contained this exchange:
  Brooke Shields: Is something wrong?
  Masterson Rat: Do you believe in interspecies dating?
  Brooke Shields: Well, I've dated some rats before, if that's what you mean.
- It got weirder in Muppet Treasure Island. Benjamina Gunn (Miss Piggy) apparently had relationships with the humans Captain Flint and Long John Silver, the former of whom abandoned her on the island after their relationship ended. Her former fiance Captain Smollett (Kermit) seemed disturbed by this revelation, but it may have been more because of her promiscuity than the interspecies aspect.
- Piggy's been known to throw herself at hunky male humans on The Muppet Show before. Christoper Reeve comes to mind. Also Patrick Wilson, drummer for Weezer, in the "Keep Fishing" video. Neither one reciprocated.
  - Charles Grodin, however, was quite enamoured with her in The Great Muppet Caper.
Out Of This World: Donna (Human) and Troy (Antarian), Troy is apparently a Human Alien, though the only time he actually appears "in person", he's a somewhat abstract ghostly form. For the rest of the series, he only "appears" by way of a communication cube, which the other characters often treat as though it actually physically is Troy.
Space Cases does this with the hinted feelings between Harlan and Catalina, Harlan and Suzee, Radu and Elmira, and Radu and Suzee. Granted as a kids show none of these went anywhere, but its still worth note. However excluding Elmira (who is a proper Green Skinned Space Teen) every alien in this series is a Human Alien. Also, aside from Radu, Suzee & Elmira, the other "aliens" are actually descended from genetically altered humans created to live on other planets in the solar system.
Tragically played with in the CSI episode "Fur and Loathing"; while all the characters involved are physically human, the victim was accidentally killed as an indirect result of his new flame's former boyfriend poisoning him with caster oil for stealing his girl... all on the basis of fursona species segregation (the victim was a raccoon, the girl a lamb, the boyfriend a wolf).
The centaurs in Xena Warrior Princess (who are all male) and human women.
Hyperdrive. Hilariously spoofed in the compulsory sex education video watched before a First Contact mission. We don't see it (fortunately) but the crews' reactions to what they are watching show it would make even Kirk think twice.
"Let's learn about another Alien Sex Disease. This crewmember had intercourse with a Glygonthian octopoid. Let's take a close look at his genitals. Pustules have developed, and on the pustules: warts. Soon, his entire groin explodes, leaving five baby octopoids, each with his face. Remember, Alien Sex is Danger Sex."
Er, why isn't Beauty and the Beast up here yet? This trope was the whole point!
Willy, the Woobie alien from V, and the human Harmony Moore had a genuine romance, unfortunately cut short by her death in the second TV movie.
The Daily Show did a short piece on a biologist claiming that humans are more closely related to orangutans or something. At the end, we see John Oliver and an orangutan doing all the romantic stuff, terminating with Oliver hanging a "Do Not Disturb" sign on his hotel room door.
Averted in The X Files. Though various monster/human relationships are seen, when one character thinks that the reason an alien took human form was because he fell in love with an Earth woman, the alien just laughs (it turns out he fell in love with baseball. And laughter).

As mythology is full of stories about romance between supernatural beings and humans, this is Older Than Dirt.
- With a special mention to Zeus/Jupiter in Greek and Roman mythology: not only is he an unfaithful god who seduces human women, he takes the appearance of various animals (swan, bull (!), a shower of gold, etc.) to do so.
- The wife of the King of Minos mated with a sacrificial bull sent by the gods and gave birth to the minotaur. This was as punishment for Minos refusing to sacrifice it.
- Centaurs.
- And Satyrs ... with behaviour as much as origins bringing this trope to bear on them and the centaurs.
In many myths, demons are unable to breed naturally, and must instead mate with a human, producing a demonic offspring. Hence the Incubi, Succubi, and various other Horny Devils.
In Genesis fallen angels descend to Earth and mate with human women, creating giants. There is an alternate interpretation for this; that the higher class merely took themselves too many lovers from the common folk with no strings attached.
Myths of griffins alleged that they would attack herds of horses, kill and eat the stallions, then rape all the mares. That's where baby hypogriffs came from.
- Er, no. Hippogriff is a heraldic beast that wasn't believed to exist even when griffins were considered real. Since the griffins are supposed to eat horses, hippogriff was seen as a metaphor for impossibly improbable thing.

Mommy, where do half-elves come from?
Daddy, where do half-orcs come from?
Derro used to be - and might still be - half-human, half-dwarf, all-insane freaks in the lore of Dungeons And Dragons.
D&D also features, as templates, half-celestials, half-dragons, half-elementals, half-fey, half-fiends, half-janni, half-minotaurs, half-ogres, half-trolls (which can be anything from half-human to half-griffin to half-stegosaurus), half-vampires, and even half-golems and half-illithids (though at least those last ones thankfully don't involve sex).
Going further still, aasimar (celestial), chaonds (chaos), draconics, genasi (elemental), tieflings (fiendish), and zenythri (law), among others, are what happen when some of those half-thingies go around and do it with "normal" people.
There are also "Heritage" feats and a "Bloodline" option, for adding special powers based on unusual ancestry, including celestial, fiendish, fey, vampire and illithid, among too many others to list.
In fact, it was implied that humanoid sorcerers have some draconic ancestry, as sorcery is how the dragons use magic - and they're pretty much the oldest race, outside of celestials and fiends - as well as explicitly stated that dragons can mate with Anything That Moves. Which fits well with their high Charisma and shapeshifting abilities. Nowadays it's implied that sorcerers have a touch of magical blood, but this can be from dragons, angels or demons, with different effects depending on which.
- D&D was so bad about everything mating with everything else that a supplemental book, the infamous Book of Erotic Fantasy, featured a chart explaining which creatures are compatible with which other creatures. That wasn't an official sourcebook, though. It did have some interesting things in it, like prostitute prestige classes and cloud giants mating with sprites.
Dragonlance is not immune from this trope: the Dragonlance setting features 'Gully Dwarves', allegedly the offspring of gnomes and dwarves. Aside from being a strange combination, Gully Dwarves are incredibly stupid creatures, depicted as being totally incapable of counting higher than two. Those that can count higher than two tend to lick beer from tavern floors.
The changeling race, from the Eberron campaign setting of Dungeons And Dragons, are theorized to be descended from the viable offspring of humans and dopplegangers coupling, though this is unconfirmed (various factions have their own varying theories about why, exactly, changelings exist).
- Note that in Standard D&D this is explicitly not the case: Dopplegangers are a One Gender Race that breed with other races, their children turn into Dopplegangers at puberty.
- Shifters or "beastkin" are similarly referred to as being a "mixed race" of lycanthropes and humans, although this, too, is unconfirmed and fiercely denied by shifters who belong to the anti-lycanthropic Church of the Silver Flame. (Such shifters insist that they existed first and lycanthropes are an unholy union of humans and shifters.)
  - The Fourth Edition Monster Manual and Player's Handbook 2 do make this the default canon explanation how the shifter race(s) came to be; longtooth shifters are descended from werewolves, razorclaw shifters from weretigers. Both are legitimate choices for player characters.
- The Forgotten Realms even has specific breeds of tieflings based on their ancestry - specifically, the fey'ri (elf-demon crosses) and tanarukks (orc-demon crosses).
- The tendency for humans to mate with other things was so common that eventually a race was created in D&D called the "mongrelfolk", supposedly a lowest-common-denominator mish-mash of basically *all* humanoid races.
- Then there is the tauric template. Not happy with centaurs? Pick a humanoid and a creature with six or more legs and mash 'em up. Just try not to think about how they came to be. (Thankfully, the answer is usually "magic".)
- Mechanatrixes, from humans and extraplanar clockwork outsiders like Inevitables. Born as cyborgs. From a living being and a magical robot.
- Although the Squickiest race is quite probably the Wildren, a race in the 3.5 edition Planar Handbook that are descended from crossbreeds of dwarves aaaaannnd (wait for it)... badgers. Yes, badgers. Admittedly, they were near-sentient celestial badgers that had quite possibly previously been dwarves because of the way that their native plane works, but still. You may find that the best way to gouge out your mind's eye is to ram a tuning fork up your nostrils.
- Maybe, but remember half-orc/half-elf are still taboo (strange thing since orc and elf in D&D are from Tolkien, who described orcs as tainted elfs...).
  - Elf/dragon hybrids, although perfectly feasible (with shapechanging assistance) under 3E rules, are such an unthinkable taboo to both species in the Eberron setting that producing one got the Death-dragonmarked elven lineage of Vol exterminated. The hybrid still exists, but only as a lich.
All sorts of human/non-human goings-on in the World Of Darkness, including vampires and werewolves (though no one would ever consider trying to have sex with a werewolf in its War-Form...unless they were pretty much invincible or into self-snuff and that got creepy really fast). On the other hand, Vampires are living corpses (although they can have sex if they choose, their sex drive is mostly so dead they're hardly ever in the mood), as are Mummies and Prometheans, so they're sterile to begin with; werewolves are born human (or wolf) and only hit lycanthrope status at puberty (in the old World of Darkness, they mate with both humans and wolves but are forbidden from mating with other werewolves); and changelings, while usually sterile due to Arcadia's nature, don't pass on any magic touches to their offspring.) Hunters are pure humans, as are Mages, and Demons possess humans so can procreate as normal for a human.
Averted in Warhammer40000 as all species in 40k are exceedingly xenophobic and view all other as lower than animals, thus making even the idea of interspecies romance horrifying and purge-worthy. However, both the Dark Eldar and the followers of the Chaos God Slaanesh do induldge in gratuitous interspecies rape, but that's primarily because their MO involves raping anything that moves.
- Or anything that doesn't move. And if it was moving and then it stopped.
- Fans of Imperium of Man respond to this trope with : "Fucking Xenos?!? Those fucking Xenos!"
- It is hinted in some of the older fluff, however, that the Ultramarines do have a human/Eldar hybrid among their number, though this is somewhat undermined by the fact that the same fluff also states that Eldar have, among other horrendous biological impossibilities, zero body fat (but for some reason the females still have rather prominent breasts) and TRIPLE HELIX DNA.
- Most, if not all, of the older fluff is generally disregarded by the producers themselves (though fans, naturally, have a tendency to latch onto elements they like)... understandably, seeing as how the oldest fluff includes such disasters as Squats (drunken space dwarves who drove around on motorized tricycles), the Sensei (immortal, sterile children of the God-Emperor, who he didn't even know existed) and the Illuminati (a conspiracy of humans who were possessed by daemons, then managed to force them out and become untouchable super-psykers as a result).
  - Actually, there is a monster (or race of monsters) in 40K devoted to this trope. Genestealers are a sub-species of Tyranids that focus on infilitrating target populations. They do this by changing a target's DNA slightly; this makes the target absolutly devoted to the Genestealer and Tyranids in general, and horny. Any child of the targeted creature (known as a Brood Brother) is less of the parent race and more Tyranid, until by the fourth generation Brood Brothers (well, Sisters) give birth to purestrain Genestealers.
- On the other hand.... Love Can Bloom.
- I prefer Love Can BLAM!. Warning! Contains HERESY, NSFW Tau, and Yeeeaaahhhh!
If it exists in Exalted and can have sex, then some Exalted has had sex with it. The Lunars above all, that's how Beastmen came to be. If it makes a difference, the Lunars have the ability and usually the inclination to ask animals first.

The highly publicized alien-human lesbian sex scene from Mass Effect. You get the romance subplot with the same alien NPC even if you're male, as she's bisexual. But that was nowhere near as publicized.
- The second game continues the tradition. In fact, more aliens than humans are romanceable in ME 2. The confirmed interspecies liaisons are newcomer Thane and Garrus for female Shepard, and Tali for male Shepard, the two latter being fan favorites returning from the first game.
  - There's even an asari option in the sequel with Morinth. For all of six seconds. You were warned, after all.
- In the sequel, The Smart Guy Mordin even gives you The Talk of the... Biological implications of such romance. He notes that chafing will result and recommends you not to *cough*... Ingest.
In The Elder Scrolls III: Morrowind and IV: Oblivion, there exists a play called The Lusty Argonian Maid where an Imperial (normal human) and an Argonian (lizard person) were about to... get it on.
- Similarly, one of the chapters in The Real Barenziah, a story in II: Daggerfall, includes the titular Barenziah (a Dunmer) and Therris (a Khajiit) getting together for some lovin'. The books are also in Morrowind and Oblivion, although the version present in both is censored by the Tribunal Temple.
- Another book in Morrowind was actually a scholarly tome on the subject of inter-species mating. It stated that all human and Elven species can and do interbreed, with reduced but still possible chances of offspring. Indded that's how the Breton came to exist. Humans or Elves and the other species, not so much. If they want to have sex, the parts roughly match up, but they are too different for actual offspring... probably.
- The Last Scabbard of Akrash, like The Real Barenziah, features a consummated Khajiiti-Dunmer romance, although with less detail. The world's backstory also includes a number of alleged Tsaesci ('vampire'-snake-people) - Breton relationships, although the books documenting such are considered propaganda in-game.
- Let's not forget that the only Romance Sidequest for any male character in Morrowind is a Khajiit woman. She's not picky, of course.
Princess Elise, the human princess of a Fantasy Counterpart Culture version of Italy had a one-sided romance with Sonic The Hedgehog throughout Sonic the Hedgehog 2006. Even though the Reset Button was pressed, fans still try to pretend the game never existed at all.
- Going back even further in the series, in early design sketches, Sonic had a human girlfriend named "Madonna◊" who resembled the pop singer of the same name. The idea was shot down before the first game was launched, however.
- Of course, in the series proper, you also have Femme Fatale Rouge (a Bat), who has scenes that could be used to romantically link her with Knuckles (an Echidna), Shadow (a Hedgehog), and even Tails (a Fox, and a very young Fox at that).
- And in the SatAM continuity, Sonic's girlfriend is half chipmunk, half squirrel. Sally is, in general, considered far less squicky than Elise. In the comics, he seems to have built an Unwanted Harem including other animal characters.
- Tails (fox, albeit a slightly mutated one) and Cosmo (Seedrian - a species evolved from plants) in Sonic X is another example of this. Apparently, the Sonic universe has Purely Aesthetic Species. And Hierarchies.
- Also in SatAM, Sonic has to compete with Antoine (a coyote) for Sally's affections. Then it's briefly hinted in one episode that Bunnie Rabbot (a half-robotic rabbit) has a thing for Antoine; they ended up becoming an Official Couple in the comics.
- In Adventures Of Sonic The Hedgehog, Sonic falls head-over-heels over Breezie, a female hedgehog in a red cocktail dress who turns out to be a robot. Robotnik also builds himself a robot wife in one episode.
- There's also Maria, but she was more like a sister to him. Still..
Riku/Mickey Slash Fic, the ultimate "AAARGH! My childhood!" moment...
- Kingdom Hearts deserves special mention here in any case, if only for the sake of the numerous Disney Animals who appear in-game, including Sora's various transformations. It's almost impossible to traverse the fandom without coming across something childhood-killing, even without looking on the kink meme.
  - Even worse, of course, came in Kingdom Hearts II where the Pride from The Lion King actually asked Sora to take over as king after he showed up. Thankfully, it was Jossed by Rafiki before they had to make a few explanations.
Star Fox 64 has Kat, which seems to have a thing for Falco (can you guess their race?). However, later romances in the series all stick to same species, as far as a blue vixen and a normal colored fox can be of the same species. According to one of Commands endings, no problemo.
- However, according to other Command endings, Krystal winds up with Panther, a... well, you figure it out.
- And of course this "Not safe for humanity" (and thus by implication work as well) strip from VG cats.
  - Or the "Not safe for humanity" implications given in Super Smash Bros. Brawl.
Pretty much any Dungeons And Dragons-based game (see below) that has any sort of romantic capability will have Interspecies Romance. It's almost blasé in D&D, though some settings make a point of having a xenophobic nation or two - almost always evil or at least repressive to take the moral of the concept from plain obvious to Anvilicious.
For a more old-school reference, there is a sex scene between the Captain and Talana in Star Control 2. It is almost a But Thou Must although if you refuse enough you can skip it.
- There is also Admiral ZEX, who there is not a (canon, at least) sex scene with, despite the fact that he has a very clear interest in the Captain. This is partly because of the fact that he's male and partly because, unlike Talana, he looks nothing like a human.
Breath Of Fire, as more or less the Furry Fandom in video game format, is full of examples.
- Breath of Fire I features the neighboring villages of Tantar and Tuntar, one of which is populated entirely by humans and the other is populated entirely by the "forest clan," people who look like this◊. The two villages get along incredibly well, and in fact, when the player first arrives, both are celebrating the fact that the first forest clan/human marriage is about to take place. And it does, though you have to do a bit of a Fetch Quest to save both villages from an imminent threat before the actual wedding. (Forest clan male/human female, if anyone was curious.)
- A cutscene in Breath of Fire II retroactively reveals that Ryu (dragon clan) and Nina (bird clan) from Breath of Fire I got together, and the current bird clan as of Breath of Fire II is weaker due to being less pure-blooded due to being descended from that pairing. That's why the bird clan in Breath of Fire II can't shapeshift without a special irreversible ritual, whereas they could go back and forth at will in Breath of Fire I. Much less extreme than the first example, since the clans in question are both basically human with some magical traits added.
- Also in Breath of Fire II, both that generation's Nina (a winged human), and Katt (a half-furry catgirl wearing no pants) develop crushes for Ryu. Ryu's friend Bow (an antrhopomorphic bulldog) has a thing for Nina's sister Mina (also a winged human). Sten (a monkey man) tries to blackmail Nina (and later Katt) into a date. And hell, even Ryu's own parents are an interspecies couple (a human and a dragon).
- Rand's mother Daisy in Breath of Fire II is of...somewhat debatable race, looking more or less like a human, though slightly larger. Whatever she is, though, she looks absolutely nothing like her very obviously armadillo son, which raises certain questions about his unseen father. Although, to be fair, the female representatives of some races (including Rand's race) tend to look much more human than the males.
- Breath of Fire III teases Slap Slap Kiss-style UST between Momo (technically a dog, though the degree of anthropomorphism is so far toward human and the ears look so much more rabbit-like than dog-like that she more like a bunny-girl than anything else) and Rei (weretiger) from time to time.
- Bleu/Deis, a somewhat perverted lamia-like snakewoman, who hits on the different Ryus throughout the entire series.
- The Bird Clan seems to love ther species so much, that, by the time of Breath of Fire III, the entire clan have essentially lost their wings, becoming boring old humans. Making the hero and heroine of every Breath of Fire game Ryu of the Dragon Clan and Nina of the Bird Clan doesn't help matters either.
Final Fantasy IV, Cecil and Golbez were sired by Kluya, a Lunarian (that is, an alien from a very, very distant world, who eventually settled on a moon orbiting the game's planet,) from a human mother. Cecil goes on to have children of his own, again with a human mother.
Final Fantasy VI, Terra is the daughter of Madonna/Madeline, a human girl, and Maduin, a satyr/Gigas Esper. She eventually gains the ability to turn into an Esper-like humanoid herself.
Final Fantasy VII, Aerith, the last Cetra, is the daughter of a human scientist named Gast, and a Cetra woman named Ifalna. Of course, the Ancients are almost entirely human themselves, so there's really not much of an issue here, until Hojo comes along and tries to mate Aerith with Red XIII, a huge talking wolf/lion that is another Last Of His Kind. There's no indication that Hojo's idea would have actually worked, though.
- Not to mention there's the abundance of Hentai on this very subject that varies from Squick to Fetish Fuel with varying mileage from person to person.
- According to the Compilation, there was at least one more, female, member of Red XIII's race, who had been his mate before he was captured by Shinra.
- Red XIII himself. Considering that his maternal grandfather looks mostly human and that the people of Cosmo Canyon are human, his mother must had been humanoid as well. Being of a human/intelligent dog hybrid, Red XIII is arguably the only example of this. Aerith mom can can be strongly argued to simply be of an ancient human clan and Sepiroth's parents are entirely human, his mom was just injected with alien DNA when he was still in her womb.
In Final Fantasy IX, Garnet and Eiko were Summoners, apparently a different species from normal people, since they were born with horns. Also, Zidane's not entirely human either — obvious from the start since he has a tail, but this turns out to be more than a cosmetic quirk. And then there was the Vivi/Quina marriage, which involved a techno-magical construct and an ambiguously gendered giant frog thing
Hinted at in Runescape between the main character and Zanik the Cave Goblin. But if this shipping is wrong or sweet is up in the air for debate.
Happens multiple times in Final Fantasy X. Heroine Yuna has a human father and an Al Bhed mother, though to be fair the Al Bhed are almost completely human in nature and appearance. Villain Seymour has (or had) a Guado father and a human mother. And the icing on the cake? Seymour is, quote, "quite taken with her," her being Yuna.
Final Fantasy XI, being an MMO with five humanoid races and all, is bound to have plenty of romance, found both in the player base and story lore. The tragic romance between Raogrimm, a Galka, and Cornelia, a Hume, became the catalyst of war. The main character of Wings of the Goddess, Lilisette, is apparently the offspring of an Elvaan and a Hume, in a game where cross-breeds were never mentioned before. Also, one cannot deny the massive amounts of Tarutaru x Mithra doujin...
''Final Fantasy XII' has a little shipteasing between Fran and Balthier, particularly in the Pharos after defeating Dr Cid. Revenant Wings expands on this - when Tomaj attempts to romance Fran, she tells him Balthier's methods were different.
- Also, there is a sidequest in Rabanastre in which you can pair a Viera up with a Hume. The Hume tells the party that he wouldn't have imagined a Viera/Hume pairing could work until he saw Balthier and Fran.
Fire Emblem: Blazing Sword, Ninian the ice dragon isn't just a possible mate for the human hero Eliwood, she's the canon partner. Even though the other two possibilities are human.
- Careful with this sort of assertions, will you? At least, Eliwood's crush on her is very obvious in the cutscenes.
- Don't forget Nergal and Aenir, the couple that spawned Ninian.
- Interspecies Romance is all over the place in Path of Radiance and Radiant Dawn. In fact, some of these romances are either directly or indirectly responsible for most, if not all of the events in the two games.
The Nippon Ichi-verse contains several examples:
- Laharl from Disgaea is the offspring of a Human and a Demon.
  - Possibly paired up with Flonne, an Angel.
- Salome (human, possibly) and Zetta (demon, but also in heavy denial) from Makai Kingdom — of course, Salome probably doesn't count as human any longer, what with having become an overlord and all.
- Adell (human) and Rozalin (demon) from Disgaea 2. Both in very heavy denial. Of course, Adell doesn't count as human either, but he doesn't know that.
- Nereids in Soul Nomad And The World Eaters mate with humans. Since they're an all female race incapable of parthenogenesis, it's required for their survival.
- Older Than They Think. The Nereids in Greek Mythology were the fifty daughters of a lesser sea god. They were fond of helping distressed sailors.
- Also possible between humans and Sepps (see Endorph ending). Might happen between Revya and Danette in the future after the Danette (male) ending. See Victorious Childhood Friend.
  - Sepp/human pairings may actually be quite common. One NPC in the game claims to be half human half sepp, Levin (sepp) has a crush on Tricia and may also hook up with Revya (if female) in the Levin-ending.
- Female Revya can also hook up with Gig, the God of Death in one ending.
Don't tell me you don't notice the UST between Sly Cooper (thieving raccoon) and Carmelita Fox (police..um..fox). And watch where Penelope's heart wanders to in the third game.
Alleria Windrunner (high elf) and Turalyon (human) in the Warcraft series, as well as Veressa Windrunner and Rhonin (same combo). There also exist Mok'nathal (ogre-orc), at least two orc/draenei, and one character, Med'an, who's the child of one of those last and Medvih, thus making him 1/4orc 1/4draenei 1/2 human, though you wouldn't know it if you saw him.
- It's also hinted that Kael'Thas (yet another high elf) had a crush on Jaina Proudmoore (human).
- Furthermore, many people speculate that Jaina has a romantic relationship with Thrall (orc).
- There's also Marvin and Tamara Wobblesprocket, who are a married couple. The former is a tiny gnome, and the latter is a human.
- And Kinelory (night elf) and Quae (human), an implied lesbian couple.
- Archaeologist Adamant Ironheart (Dwarf) and Priestess Kyleen Il'dinare (Night Elf) seem to have something going on, too. At least, she doesn't mind him calling her "darling".
- The Troll Zebu'tan is forever trying to woo the Blood Elf Alys Vol'tyr. She isn't very receptive to his advances, but her dialogue makes it pretty clear that it has little to do with his species; she doesn't want him because she's spoken for and he's a creep.
- World Of Warcraft has several "Steamy Romance Novels" that can be pickpocketed from NPC humanoids. One of these describes a romance between a male human paladin and a female undead rogue. Another one of them describes a romance between the same paladin and a female gnome warlock.
  - And we'll just stay out of the realm of fanart and doujins for the sake of sanity.
Ever play the classic arcade game Joust? When you destroy one of the vulture riders, the vulture lays an egg that you must collect to complete the round. If it is allowed to hatch, an enemy human emerges, and a new flying steed comes in to pick him up. The question is, why does this happen? An explanation comes to mind...
Tales Of Symphonia: Dawn of the New World gives us not one but two canon interspecies pairings: Marta/Emil and Aqua/Richter, though the former eventually can live out their lives as humans and the latter is one sided.
- You forgot the Angel/Human that occurs in the first game.
In The Sims you can sleep with robots, zombies, vampires, plant-creatures, aliens, werewolves, etc.
Mega Man Zero 4 introduced two characters, Neige (human) and Craft (Reploid). The latter even explicitly stated that he fell in love with her, and their romance is a very important turning point in the game!
- Also, don't get me started on the tons of hints concerning Ciel's feelings for The Hero Zero. And not just in the main medium, in fact...
- In one of the games in the Zero series, there is an NPC that looks like an old man - despite being a Reploid. Years ago he fell in love with a human girl and married her. As she grew older he had his appearance modified to match her age. When she finally succumbed to old age, he chose to keep his elderly form as a way to remember her.
  - Of course, all that gets done away with in Megaman ZX...
Earthworm Jim, whose name speaks for itself, has a huge crush on Princess What's-Her-Name, who is a humanoid insect.
Ar Tonelico: a part-RPG, part-dating sim whose dating sim aspects revolve entirely around relationships between humans and Reyvateils - an all-female race of magical girls whose ancestors were artificial intelligences created from scratch using alchemy. You can also date said at least one of said ancestors, who's immortal and still around. Oh, and the fact that Reyvateils are basically a slave race on at least one continent adds to the squick.
The first Parappa The Rapper game contains the heart-warming plot of an anthropomorphic dog trying to romance an anthropomorphic sunflower.
The Legend Of Zelda: The Wind Waker, a girl named Maggie asks you to deliver a love-letter to her love at the Forsaken Fortress. As it turns out, the person she met and fell in love with while being held captive there is actually a Moblin.
- Moe is torn between wanting to return the affects and wanting to eat Maggie.
- The Oracle games have a good dose of this, too. In Seasons, Link (Hylian) dates the Subrosian pop star Rosa. In Ages, Link gets propositioned by the Maku Tree, and Queen Ambi (human) pines for... the undead Piratian Captain. And apparently it runs in Ambi's family; her descendent Ralph is possibly romantic with Nayru, who appears to be a Hylian.
- Don't forget Link's Accidental Marriage to Princess Ruto in Ocarina of Time. While she does let him off the hook due to the "Sage of Water/Hero of Time" thing, she really did want to go through with it. Also, in Majora's Mask, the girl who runs the "Treasure Box Maze" game will flirt with you when you're wearing the Zora Mask.
Shiki and Arcueid are even the official couple. It seems to be a much bigger deal in story than out of it. There's only been one child before this from between a True Ancestor and a human.
Crow, the heroine's bird companion from The Longest Journey, claims he's made advances to female birds of multiple species, although it's not clear if his efforts were successful or if he's just making it up.
Pokemon, mentioned above in the anime section, gets another mention here due to the prevalence of Hot Skitty On Wailord Action, which appears more readily in the games than the anime.
- Pokemon are technically one species from a biological standpoint, of course. Skitty and Wailord can breed and produce fertile offspring, and as such are technically no more distantly related than a chihuahua and a grey wolf.
- According to the Sinnoh legend, at one point, humans and pokemon "ate together at one table". According to the wikis, the literal translation explicitly stated marriage occured between the two.
On a related note, a ~~Japan-only~~ Virtual Console Genesis game called Pulseman, which was made by the makers of Pokemon, tells of the titular character being the offspring of a man and an AI. Yes, man and machine had a baby. By combining his DNA and her program core. When he digitised himself insider her. So Yeah.
Most of Ratchet's Girls of the Week in the Ratchet And Clank series qualify. For a slightly more brain-damaging version, there's an amnesiac Captain Qwark apparently once hooking up with a monkey. (This revelation is, naturally, treated as Too Much Information).
In Mana Khemia one of the human (sort of) protagonist's possible love interests is a catfolk named Nikki, and if you manage to get her ending, not only do they get married, but they also have kids.
In the Lunar series we have Jessica, a half-beastperson and Kyle, a human in Silver Star and Ronfar, a human, and Mauri, a beastperson, in Eternal Blue. Not too sure if Alex and Luna could count because is human and goddess-reincarnated-as-a-human really Interspecies Romance? We're not sure about Hiro/Lucia, for that matter.
This isn't very common in the Super Mario Bros series, aside from dragon-turtle Bowser's one-sided crush on humanlike Peach. Still, there are two such romantic pairings in the RPGs, and both involve a Koopa (turtle) and a Boo (ghost). Such a pair were two of the four heroes in the backstory of Paper Mario: The Thousand Year Door, and another couple can be found doting on each other in Mario And Luigi: Bowser's Inside Story. Given the general lack of Interspecies Romance in the series, it's odd that the ghost-in-the-shell idea is so popular.
- Actually, pretty much all of the girls in Thousand Year Door seem to like Mario. All four of his female party members (a Goomba, a talking cloud, a shadow siren, and a mouse) give him a kiss at one point.
- Possible justification for the Koopa/Boo romances: Perhaps the Boos were Koopas before they died, although that still doesn't solve the necrophilia bit.
  - Wouldn't they be Dry Bones, then?
  - Dry Bones = Body. Boo = Soul.
    Next Question.
  - On a slightly squickier note, many, MANY fans are attracted to Vivian, who is some kind of shadow monster. And may or may not be a cross-dresser.
Giants Citizen Kabuto: Baz and Delphi here
"we've got to help delphi, yes she may be diffrent to us, slightyly taller and a diffrent colour but I love her, you hear me, I love this woman!"
Rogue Galaxy have Deego (big bulldog person) and Angela (the not-quite-elf).
Gish has a titular protagonist resquing his human girlfriend. And in A good ending they have even get married.
In Dragon Age, none of the party members you can pursue a romance with (consisting of three humans and a male elf) care what race the player character is, be he or she a human, elf, or dwarf. However, if a dwarf, the romantic interlude is as awkward as one might expect...
In Brutal Legend, this is how Eddie came to be. Demon Emperor Succoria and her human slave-turned-assassin-turned-lover settled down in the future after Succoria realized that demons would lose control of the world and humans would come to rule the Brutal Land, and she had a Villainous BSOD.
In the art book for Phantasy Star IV, there's a bit of information about what happened to the heroes after the events of the game; Chaz apparently dies of illness sometime before he's thirty, leaving Rika, who has since become a guild hunter, to care for their young son, Rui, by herself.

There She Is!!(watch it here), in which a female rabbit falls in love with a male cat. The interspecies part of their relationship plays a big role in the plot: Such romances are extremely frowned upon in their society.

Dungeons and Denizens have an offspring between a lich and a medusa, Grim Tales has an offspring between the grim reaper (skeleton-style) and a woman, while Order of the Stick has Xykon the skeletal lich say "I'm no a disgusting biophiliac, yuck!". Also, undead are debatably not a separate species. But since without male organ flesh, they can't mate naturally at all, the unnaturalness of it all puts them as a different species (i.e. by science fiction definition, if they can't mate naturally it's another species). Squick, and reverse squick!
- Then how the *beep* does Twilight work? Or are their vampires alive?!!??!?!??!?!?!?! (Bram Stoker is turning in his grave)
Variation in Misfile. Ash and Rumisiel pretend to be this, which would be Angel/human. However, it's not a real relationship, as Ash only tells her dad the Rumisiel is her boyfriend as an explanation as to why he's living there. Also, none of the humans know he's an angel, except for Ash and Emily.
The central theme of Kevin And Kell, although the world of Domain doesn't treat species the same way: the general division is carnivore/herbivore/omnivore (wildcard?)/insectivore. Then again ... Lindesfarne/Fenton and Danielle/George involve former humans.
Here it comes ... El Goonish Shive. Tedd (human) and Grace (..um..human/squirrel/alien/another alien shapeshifter). The demonic duck also claims to indulge in this quite often. One of Elliot/Ellen alternates was in a relationship with Half Human Hybrid boy, but this one didn't worked out very well (due to the alien psychophysiology).
- Also note the Uryoms, who are ambisexual, can be attracted to anything thinking and reproduce with anything moving (regardless of species and sex of "DNA sources"), but not in a way as "fun" as the Asari.
Outside Interference has Hollie [rabbit-person] actively shipping Kate [raccoon-person] and Gina [uncertain species] Petting Zoo People all around.
- It's not interspecies if Kate, Hollie and the rest of the cast honestly don't have a clue what species Gina is.
Ozy And Millie has very little of this in its past (both leads are revealed as pure descendants of their natural parents, although Ozy is adopted into another home). But then, Ozy's father (dragon) and Millie's mother (fox) get romantically involved, and are now ~~getting~~ married.
Dominic Deegan: Jayden and Milov Danovich (also human/werewolf).
- Also seems to be leading this way with Kiya (female Orc) and Hansi (normal human) which started here.
Freefall plays a lot with this.
- Possibly best summed up in the punchline of this strip.
- And/or this one◊.
And let's not even get started with Tales Of MU.
Tally Road leans on this trope very heavily, too- working the angle that for most of the cultures involved, this interspecies screwing is both perverse and fairly common. There's literally a cat-house on a wolf planet (or 'Nerre-house' on a 'Runge' planet) and one of the cat ladies argues against getting into kink clients, pointing out that they are not kinky so much as they are exotic and different in the 'Runge' context. Another feline, in a moment of frustration, sighs at being 'judged by shaggy animals', upsetting his wolf companion and giving a tip-off of the cats' unspoken attitudes towards other species.
Celia and Roy (sylph and human), Nale and Sabine (human and demon) in Order Of The Stick.
- And then there's the "very ugly backstory" of Therkla the half-orc ninja (human father and orc mother).
- Meanwhile, Roy's mother is happily anticipiating the logical consequences of Celia and Roy's romance.
  "I want to be able to hear the pitter-patter of little feet — or the whoosh-whoosh of little wings, as the case may be."[1]
When she was trying (unsuccessfully) to put men behind her and find a good woman to settle down with, Monette in Something Positive had a bit of a breakdown, and ended up getting arrested in a zoo. The most embarrassing part for her was that the koala was still a male (mildly NSFW links).
Matoya and Bahamut from 8-bit Theater (Witch/Dragon). This Squicks the Light Warriors greatly.
Last Resort features it as a trait of the Celeste to crossbreed between as many species as they can, creating a race that can only be detected by how many wings they happen to have. At least one Celeste's backstory apparently involves a Cult of personality centered around him and the many, many women he tricked into having his children. It's Squicky enough before you even throw in the fact that he's a rather large humanoid (albeit with some feline traits tossed in) and the women he brainwashed were all small, furry, feline-esque Talmi.
Dan And Mabs Furry Adventures has a table of possible hybridizations between the various races in its world.
- The tale of Brian (a being) and Burasi (a dragon)...
- It's also worth mentioning that Jyrras's parents are a kangaroo and a kangaroo rat who met when an accident in the personal ads department got the K species section mixed up. Seriously.
Penny Arcade has this gem.
- And this one.
Schlock Mercenary plays with this with amorph regeneration and reproduction. It doesn't rhyme with "pentacle rex"...
Parallel Dementia has a zombie/human relationship. Squick!
In The Inexplicable Adventures Of Bob, Bob first met Princess Voluptua and the jellyfish creature Ahem when they were trying to escape an unthinkable Arranged Marriage to one another. Bob's girlfriend Jean is currently convinced that Bob and Voluptua have feelings for one another, despite the fact that Voluptua's real form is a giant insect (although her assumed human form is, indeed, quite attractive).
The Cyantian Chronicles: And How!
- Contrary to what this article may make The Cyantian Chronicles seem like, the requisite majority of couples are same species. Interspecies romance isn't commented on much (in universe) for pairings that result in deformed offspring. Said pairings are frowned upon because of the suffering the children go through. For more thorough details read this page from the Shivaewiki
- Chatin and Collin are a Skunk and a Raccoon. (Both genetically engineered from the setting's felines)
- Cesilee and Marcus are an ocelot/puma hybrid and a human, though the relationship is more of Cesilee's obsession with Marcus than anything else. (Played For Laughs)
- The parents of the Cisaan Family are a Tiger and a Rabbit. (Offspring are genetically engineered, which was a first and a massive controversy in universe.)
- Rama's Parents were a wolf and a Liger (Double hit there. Also pertinent to his and Vin's backstory.)
- Chatin and Twinky are technically a Wereskunk (Human Cil Hybrid with Skunk Characteristics) and a genetically engineered strawberry scented skunk.
- Alexandera, adopted human mounty (Mounty = Feline) princess has a mounty (feline) boyfriend. (Alexandera has a few issues.)
- In years past Syrys, a wolf, was in love with Danie, a fox. (Impossible to breed with each other.)
- Vincent's Father is Rama, a wolf/feline hybrid and his mother was a wolf. So Yeah.
- If you're wondering about Chatin: Yes, she does have a Love Dodecahedron worth of suitors. Her third suitor is another skunk, which is a subversion for this trope.
In Vinci And Arty, the titular couple consists of a male Raccoon and his Yumar (aquatic cheetah) mate, though they're not the only example in that comic.
In Sluggy Freelance Riff starts hitting on Aylee the moment she shifts from her dragon-like form to a Green Skinned Space Babe (complete with Non Mammal Mammaries). Torg was quite Squicked by this.
- Later, Riff explains it was only because when she was suddenly like a woman, he went on autopilot; under the indifferent surface, he has major issues with women and can't deal with most of them normally, but he still manages to get dates by looking cool (or something) and goes trough a lot of girlfriends.
- This is also how Leono bred his wraith army. Aylee was the one to find this Squicky.
- While we've never seen him in an actual relationship, Bun-Bun (a rabbit) does show a sexual interest in human women. It's also debatable whether Kiki (a ferret) has romantic feelings for Bun-Bun, or if her affection for him is just part of her general Friend To All Living Things personality.
Terinu has the alien title character falling for Gwen, a human girl his own age. In a canon text story by the comic's author, a human girl also apparently has a long running affair and eventually becomes engaged to a vulpine.
The erotic webcomic Dreamwalk Journal is all about this. The planet Cyeatea is inhabited by numerous intelligent humanoid insect and arachnid species, all nude with exaggerated sexual characteristics including female Non Mammal Mammaries. There's lots of sex between species (some of it in the form of ritual combat, eliminating the need for real warfare) and with a couple of visiting human women.
In Everyday Heroes, G-Nat (a human/insect hybrid) and his girlfriend Julia (fully human victim of a shrinking experiment) are the proud parents of 137 bouncing baby larvae.
Fur Will Fly and Coming Up Violet have had more then a few interspecies (interracial?) romances, but interestingly enough, the only confirmed child resulting from such a union is a mouse(mom)/human(dad) hybird who has her mother's body, and her dad's mind.
The bartender in Corner Alley 13 is the result of an interspecies romance between an ogre and a mermaid.
In Gunnerkrigg Court, Kat and Aly's relationship comes to an end when the latter transforms into a bird... Afterwards, any time the subject of birds (or even Psychopomps that look like birds) comes up, Kat jokes about being attracted to feathers and beaks.
Kat: And this Muut guy... he ah... has an owl head and doesn't wear a shirt you say?
Antimony: Steady on there, girl!
Kat: Haha!
- Also, the fox Renard was smitten with the human Surma (who, considering that she married someone else, most likely didn't reciprocate). Renard also "would be interested in watching" two human girls kiss.
Perry Bible Fellowship with Bacon Egg◊ and Not Today Little One◊.
Housepets has Sabrina (cat) and Fido (dog), but cat/dog relationships seem to be generally disliked by the neighborhood animals.
Buck Godot subverts this. Buck dismisses Louisa, who is human, (albeit of a different sub-species), who has been modified to be irresistible to men as "too skinny". He also, when dropping in on his alien bartender's girlfriend sunbathing in the nude comments that "You aren't compatible with humans! I don't even know which bits I'm supposed to be looking at!"
- Of course, there's also the small issue that Hoffmanites like Buck, coming from a high-G world, tend to find other humans "too fragile". Meanwhile, the above-mentioned Ms. Louisa Dem Five proudly runs a multi-species brothel...
From WTF Comics: Anna & Smoke, Solkan & Vexana, Niami & Ngreth, and, possibly, Straha & Maguna.
Benny, of Looking For Group, is often called a "halfbreed", suggesting that her parents were of different species. However, since she was born in prison, the circumstances of her conception may have had very little to do with an actual relationship between her parents and more to do with the less savory aspects of prison life. Benny, herself, was at one point in a relationship with Sayl, a human, and some fans have speculated that there may be a future relationship between her and Cale, an elf.
- The Benny-Cale pairing is now canon. Canonically consummated, too.
In Stubble Trouble, most of the furry characters are in interspecies romances. A few of the characters like Rennon, Ally, and Gynette are hybrids from their respective parents.
Sabrina Online is a rare case when many of the characters are hybrids of interspecies romance to begin with; Zig Zag had a Siberian tiger grandparent, resulting in her signature stripes, Thomas Wolf is actually only half wolf, but it was his mother that was the non-wolf fox, so his name is. More recently, pure skunk Sabrina is in a relationship with pure raccoon R.C., plus at one time had a rabbit Stalker With A Crush. More confusing is the relationship between married couple Thomas Wolf and Amy Squirrel, who have a boy named Timothy Wolf-Squirrel (who is also a quarter fox, remember).
Pretty much every Furry Comic features this trope to some degree.
In an early arc on Fans, Rumy falls in love with an alien that resembles a glowing square with two eyes(the aliens are nicknamed "Xenochicklets"). The Xenochicklet ultimately realizes that their species are incompatible.
In The Whiteboard, there's Jake (skunk) and Pirta (snow leopard) as a couple. The other pairings so far have had both parts of each pair of the same species (or close enough, with two varieties of lynx dating).
The titular character of The Kenny Chronicles is a fox with black and white catlike fur (apparently there was a wild party). Also most of his girlfriends that have been shown are either foxes or cats (not sure if either of those count), though one was also dating a dog.
- It seems likely that Kenny's half-brother Patrick is also a hybrid of some kind (what species is blue?)
Harkovast devotes an entire page to explaining the various implications of the various races forming romantic relationships.
The entire plot of Twokinds is built around this trope.
In Teh Gladiators, a World Of Warcraft webcomic, a murloc named Yolanda develops a crush on the human Vallant, which is most definitely not reciprocated. It doesn't stop her from smothering him with affection, going berserk when he's hurt, or sparing his life after he's captured by the Lich King (something that turns out very poorly for the latter).
Slightly Damned has Buwaro, a demon, and Kieri, an angel, falling in love. This trope has resulted in numerous issues with their relationship.

Carmilla and all her more-or-less human entourage, in the Whateley Universe. In fact, with a major-league lust demon for a father and a human/Deep One hybrid mother, Carmilla is also the result of one of those...and from what we've seen of her dad since he showed up in the stories, which basically paint him as a devilishly charming rake with some trouble keeping his tentacles to himself who honestly dotes on his only daughter, romance may well have actually figured into it.
- Aside from the above, we've also seen hints at possible romance between one or two of the students and members of the local tribe of lycanthropes, and of course there are plenty of mutants whose mutations have forced them into more or less inhuman forms with little hope of reprieve. (The technical term is GSD, for 'gross structural dystrophy'.) While the latter may still be technically and legally human, speculations about their potential present or future love-life (such as the Fury Twins idly musing on their chances of finding a boyfriend) necessarily do invoke this trope.
Protectors Of The Plot Continuum: Agents Alec and Verra are a married couple. Alec is a relatively normal human, and Verra is a dragon. Luckily she can shapeshift into a human form, or their son would take a lot of explanation ... Also, the anthropomorphic fox Agent Drake has developed a crush on Agent Stormsong, an anthropomorphic weasel (who, sadly, can't stand him). Stormsong is living with Agent Skyfire, a stoat, and raising two adopted children with her, so everyone assumes this is another case of Interspecies Romance even though it's not.
- At least not under normal circumstances. That was hardly "romance", though.
- The leaders of the Black Cats' Parma Division, Twp'atwt and Serna Tjan (an anthro pine marten and human respectively), also appeared to be lovers.

In My Life As A Teenage Robot, there's Sheldon's Dogged Nice Guy crush on Robot Girl Jenny Wakeman.
- The fact that she's a robot doesn't stop Jenny from having romantic feelings for human men. Nor does it stop fans from writing fanfics about Jenny becoming a couple with Brad (though some of these stories do use the idea of Jenny becoming human...).
- In fact Brad also had a robotic love interest in a couple of episodes. Along with Sheldon's one episode crush on a disguised Vexus.
Elisa and Goliath of Gargoyles. Complete with plenty of angst about it, especially when a magic spell briefly turns them into the same species.
- Demona and Macbeth are another Interspecies Romance, albeit gone horribly sour. Nevertheless, they remain practically married after being Cursed With Awesome by some of the Fair Folk. ("Forever and eternal bound / And each the other's pain resound...")
The Chip/Gadget/Dale love triangle in Chip and Dale Rescue Rangers: Two chipmunks fighting for the affection of a mouse. One episode involves a young Squirrel with a crush on Chip, and in another Dale hooks up with a Bat.
On the Transformers Generation 1 front, you have the episode, "The Girl Who Loved Powerglide." Three guesses what it's about.
- From the same season, "Sea Change" paired the Autobot Seaspray with an alien humanoid woman whose people guarded a magical spring that let any living thing that entered it assume any shape it wanted to.
- The Transformers wiki has a list. It comes up more often that it, strictly speaking, should. Unless, of course, there's a writer with a fetish.
So far Ben 10 has seen a marriage between a cousin of Ben's and a sludge-like shapeshifting alien, and a visit from Grandpa Max's Green Skinned Space Babe from his MIB days, in addition to obvious romantic attraction between a mostly humanoid four-armed alien and a floating tentacled brain.
- The sequel series Ben 10 Alien Force is built on the premise of multiple Half Human Hybrids whose parents are all aliens who fell in love with humans and went native.
In Futurama, there have been numerous interspecies pairings. Leela and Zap were mutant plus human. Kif and Amy were alien plus human. In "A Bicyclops Built for Two", Leela and Alkazar were mutant plus shapeshifting-alien. In "I Dated a Robot", Fry and Lucy Liu were human plus robotic clone ("metal fever"), Then there's Bender and the real Lucy Liu (robot/human head) and Bender/Planet Express Ship.
- Not to mention an extra-dimensional being falling in love with, and attempting to mate with, our entire universe in the second movie.
The Nickelodeon cartoon Catscratch has Gordon, a cat, in love with his neighbor, Kimberly. (He calls her "Human Kimberly". Guess what species SHE is.) Making things worse, Kimberly is eight years old and while Gordon's age is never specifically mentioned.
Jake/Rose on American Dragon Jake Long (dragon/human... okay, shapeshifting-dragon-with-a-human-form/dragon slayer).
- Technically wouldn't Jake be half-shapeshifting-dragon-with-a-human-form because his father is regular human with no magical ancestors or abilities?
Brian (an anthropomorphic dog) of Family Guy has had a few human girlfriends, and has even had sex with some of them. This is portrayed as perfectly normal in the show's universe.
- So normal in fact, that Brian acts ashamed when he is attracted to other (non-anthropomorphic) dogs.
- In another episode, his gay cousin Jasper is poised to marry his human partner. The entire episode is a commentary on the legality (or lack thereof) of same-sex marriage; the fact that one is an animal is not even brought up. It isn't odd if you take into account that, in an earlier episode of the same season, it's revealed that Brian married Lois when they thought that Peter died in the sea.
- On a side note, Brian had a child with a human woman in a season 6 episode.
Pinky And The Brain: Pinky's recurring Love Interest is a horse. This Squicks Brain (who is only interested in other mice) considerably. When Brain creates a clone (known as "Romy") who gets infected with Pinky's DNA, Romy eventually starts dating a human woman, which Brain protests as well.
- There was also one episode where Pinky fell in love with a seal. It's also worth mentioning that the one time Pinky was ever kissed by a female mouse, he ran away screaming.
- Brain's recurring love interest, Billie, is also courted by a hamster named Snowball.
- Pinky also once fell in love with a pig on in the only half-hour Pinky, Elmyra and the Brain episode.
This has happened in Danny Phantom with a ghost prince desiring a human bride, though most of any ghost/human romance is between several human girls and the main character who's a ghostly Half Human Hybrid. Everybody likes to ignore the idea that the majority of them are undead. The main character is is only half undead, however the hell that works. One quarter dead?
- Word Of God has said that ghosts are a species of their own, rather then all being people who have died. Though at least some of them are.
Krazy Kat is besotten with Ignatz Mouse.Officer Bull Pupp would really prefer less mouse in that..
The next-to-ur example: Clarabelle Cow and Horace Horsecollar in Disney cartoons and comics. Early on, the two are romantic to the point of being engaged (comics, 1932). Later, they're back to being a dating couple, with Clarabelle occasionally seeing Goofy as well — in one recent comic book story ("With Friends Like These," 2006), clearly doing so to make Horace jealous, though innocent Goofy misreads the situation as platonic and doesn't realize how his friend is using him.
- There are also many relationships between ducks and frex geese. Closer than most of the other examples on this page, but still different species.
- There are geese within the McDuck family tree as well. Donald's cousin Gladstone Gander for instance is the son of a goose and a duck.
A Halloween Episode of The Simpsons has a The Island Of Dr Moreau spoof where the characters are turned into animals. After Marge is turned into a puma, she goes tell Homer about it... and since the lights are off, they both have sex. Homer only realizes the changes seeing how scratched he got.
- At the end of the episode, Homer gets turned into a Walrus and is shown massaging Marge with his tusk... Yes.
Eva, the human heroine of Oban Star Racers, gets a crush on the handsome alien prince Aikka. By the end of the series, it's puppy love.
The Backyardigans: Pratically all pairings, considered they're all of different species. Bonus points go to any pairing with Uniqua, who we don't even know the species of.
Classic Looney Tunes typically have Pepe Le Pew trying some unintended interspecies romance when he pursues... um, any cat with a white stripe painted on it. (Then, in a sticker book, he shuns a skunk with her stripes painted over!). Tiny Toons had Fifi La Fume (Skunkius sexius, I think, when she came in on a ~~Coyote-Road Runner~~ Calamity-Little Beeper story) continue the tradition.
- Tiny Toons also occasionally set Fifi and Hampton (a pig) up on dates.
- One episode paired Babs Bunny and (human) Montana Max, although they were not quite themselves at the time and Buster, in trying to keep Babs from walking down the aisle, makes the point that Max isn't her type, not even her species.
- Can't forget Dizzy (his generation's Taz) and his three human girlfriends. An extra level of squick is added when you consider that Dizzy is a kid and the women are... well, women.
- What about Bugs Bunny (when he dresses in drag) and Elmer Fudd (or Yosemite Sam in Hare Trimmed and From Hare to Eternity)?
A romantic subplot of Madagascar 2 involves Melman the Giraffe attempting to admit his feelings towards Gloria the Hippo.
- Also, a penguin marrying a dashboard hula girl. Ser'sly.
There are hints of something more than friendship between Vinnie and Charley in Biker Mice From Mars. One episode also has Greasepit fall in love with Charley for a short time. Another episode has a whole line of women swooning over Modo; while they could arguably be reacting to his suave act, at least one calls him cute. Yet another episode has Modo falling for a bird-woman of some sort.
The 1936 Silly Symphony Elmer Elephant is about an elephant whose girlfriend is a tiger. 'Nuff said.
- Likewise, Music Land, released a year earlier, has a saxophone in love with a violin (Interinstrument Romance?). Then, for added Squick, the saxophone's father ends up falling in love with the violin's mother.
An episode of Courage the Cowardly Dog features a rabbit in an abusive relationship with a dog. There's also a lot of subtext between the rabbit and her cat friend.
- In another episode, a goose god becomes infatuated with the human mortal Muriel, and later drops her in favor of a nonliving pickup truck.
Cat R. Waul/Tanya Mousekewitz, in an astonishingly emotional, romantic and frankly creepy scene from Fievel Goes West. There's also a surprisingly large amount of fan material◊ for the couple.
John Stewart and Hawkgirl in Justice League.
Spongebob, a sea sponge, apparently had a crush on Sandy, a squirrel, especially in the first season.
Little Bear's friendship with Emily, a human, is oddly romantic like, even for children (um, and cubs) their age.
- Emily's birthday episode seems to be full of innocent romantic subtext between the two. Emily doesn't even say they will stay together forever as friends,she just states together forever.
- They even pretend to get married in one episode.
Kitten and Fang from the Teen Titans cartoon are respectively a human (or at the very least human-looking - depending on whether or not that's a suit on her father Killer Moth) girl and a part-spider boy - that "part" manifesting itself as having an entire gigantic spider for a head - in a presumably chaotic and off-and-on but somehow working girlfriend-boyfriend relationship. And they're one of the few thoroughly canon couples, getting the only onscreen kiss in the series unless you count the movie.
- How can you not mention Robin and Starfire? She's an alien and he's a human.
How can South Park not be up here yet? The least offensive thing they did with this trope was get a pig and an elephant to get it on!
Whenever the Chipmunks and the Chipettes were not seeing each other, they show interest in humans. In fact, in The Chipmunk Adventure, the Chipettes end up in a harem because a young Egyptian prince fell in love with Brittany and wanted to marry her.
Descent into tribal loonydom, constant warfare and, to top it all off, countless male human inmates engaging in reproductive sex with the local canaries. Just some of the crazy shit that happens when the Warden isn't around to run Superjail!
Happens several times (mainly to Jay) in the Men In Black animated series. The most serious relationship is between Kay and an alien cop (Kay's feelings for his long lost girlfriend prevent him from going to far).
In the original Teenage Mutant Ninja Turtles series, Raphael shared some sparks with Mona Lisa, a human girl who got mutated into a lizard girl. People who came to like the pairing then became dissapointed when she turned out to be a girl of the week.
- Also in the original animated series, Michelangelo had a thing going with a humanoid alien named Kala.
On that note, while the second Ninja Turtles series did not feature any explicit romantic attachments for the turtles, it did feature its own interspecies romance between Cody Jones (a human) and Starlee Hambrath (blue-skinned alien cutie).
Star Wars The Clone Wars recently had a Twilek/Clone human pairing.
If you think about it, many of the couples in Winx Club could count as this. The girls of the Winx Club are fairies, and the specialists are... human-looking aliens, I guess. (or fairy and wizard in the case of Layla and Nabu) Near the end of season 4 we learn that Roxy's mother is Morgana, the queen of the fairies. In the last episode of season 4, Morgana reunites with her husband Klaus (a human).

Bat Boy: The Musical features a romance between the Bat Boy (Edgar), and Shelley .
- The above is encouraged by the Demi-God Pan, in the midst of a rather-large, MUSICAL, inter-species orgy.

Parodied by this shirt.
- Also this one
Sadly, parental disapproval averted Herman's and Sally's inter-crustacean romance in the Smothers Brothers' comedy song "Crabs Walk Sideways".
The video for "Opposites Attract". Live Paula Abdul with an animated cat? Who came up with that idea?

'Home video shows'. In such a context, an armorous rabbit trying to mount a cat or dog is usually seen as hilariously funny.
There is another nature video of a chameleon unsuccesfully trying to mount a turtle, luckily the turtle's shell rendered it impervious to the assault.
It was probably saving itself for the right shoe.
Mules/hinnies and ligers/tigons are the sterile result of romance between two closely related but separate species.
Some scientists believe that modern humans (Homo sapiens) and Neanderthals (Homo neanderthalensis) could interbreed. This raises questions on the implications of cloning a Neanderthal.
http://news.bbc.co.uk/2/hi/science/nature/7379554.stm This seal and this penguin. Though the specifics don't say if it really was sexual in nature, it's more amusing to treat it as such. Unless you're the penguin.
Many birds imprint on those who raise them, whether that's their parents, members of another species, humans, or the feed wagon. Most of them go on to court and mate with their own kind, but for some, imprinting on a human leads to them believing that humans are desirable, and their own kind just isn't interesting. In the case of at least one endangered whooping crane, there were so few of her kind that she had to reproduce, and she couldn't be artificially inseminated until she was "in condition". This led to having a human who met her specifications (Caucasian man of medium height with dark hair) court her for several weeks so that she thought she had a mate and became fertile. It's Interspecies Romance, and for once "Romance" isn't a euphemism.
Prominent television and film aliens, such as Spock, the Doctor, or Six, get a lot of real-life fan mail. Quite a bit of it is addressed to the aliens themselves, rather than the actors who portray them, and some of it is erotic and/or consists of marriage proposals.
On the other end of the spectrum, there was a farm in Washington state that was run for humans who wanted to have sex with animals. There was no law against bestiality in Washington State until the farm ended up in the news...at which point it was banned in one of the fastest referenda in history.
Not exactly interspecies romance: The black swan Petra from Münster, Germany who fell in love with a white swanshaped paddleboat.
"You are being shagged...by a rare parrot."
One of the earliest scientific studies of dolphins done in the 20th century was done by a woman whose sole motivation was wanting to have sex with the creatures. There's a link somewhere out there on the interbutts.
"Not really romance. But I suppose it can go here."
