Interspecies Romance/Comic Books

FIN FANG FOOM! Has absolutely no genitalia whatsoever! FIN FANG FOOM! Oh, you cannot]] imagine how pissed off he is.
 * All over the freaking place in Sonic the Hedgehog. And a future arc, "Mobius: 25 Years Later", suggests they'll have children.
 * It expands to "No Biomechanical Barriers". The same arc suggests Bunnie, who is robotic from the waist down, will have children, too!
 * Bone has Fone Bone and Thorn; while it's more played as Fone Bone being in love with Thorn, Thorn never says anything about not being in love with him back, and
 * 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 whatever he wants to be) and Raven (half demon.)
 * There are other Titan couples as well, such as Superboy (human/alien hybrid) and Wonder Girl ( human demigod).
 * 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). This was played way too straight in The Movie.
 * 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.
 * For a long time, the X-Men had Dazzler (human mutant) and her husband, Longshot (interdimensional alien). Since their divorce, Longshot seems to have jumped on the Boldly Coming bandwagon of interdimensional relations.
 * Depending on which origin story you actually believe, Rictor (human) and Shatterstar(alien-ish.) are this.
 * 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).
 * The Evolution animated series also has Nightcrawler/Amanda (a human).
 * 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.
 * The series Smallville addressed the essence of Niven's concerns by noting that the "training" that Jor-El had arranged for his son included "control" in that specific aspect. Apparently Clark's parents were expecting him to get involved in an Interspecies Romance and prepared him for handling the tricky aspect of intimacy.
 * Also from DC, John Stewart married Katma Tui (alien) and had a long-standing relationship with Merayn Dethalis (also alien). The Justice League cartoon paired him up with Hawkgirl and featured Katma as an old flame who he was still on good terms with.
 * 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.
 * 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. Okay, brief explanation, here, Comet is actually a centaur who was cursed and turned into a horse, but can be human whenever a comet passes the Earth. Thus, he was in human form at the time, 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.
 * Elf Quest: I'm gonna have to spoiler this whole thing because it involves a major plot revelation.
 * This disdain is hypocritical since
 * 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), and Bouncing Boy (Human)/Duo Damsel (Carggite).
 * Just about all major cast relationships are Cross-species; the Legion is compromised of tons of different species hanging out together 24/7, almost all raised with no species boundaries whatsoever.
 * 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 Fire Breather 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.
 * Nextwave FIN FANG FOOM! Has been burning with the desire to mate since 1956!
 * The Star Wars EU comics have their fair share of Interspecies Romance.
 * The downsides to be explored a bit more in others. 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.
 * The Rogue Squadron series had a romance between a Calamari and a Quarren: Romeo And Juliet IN SPACE!, in short. And in one arc it was implied that Janson and Hobbie slept with a pair of Bothans.
 * 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...
 * It's pretty much taken for granted in the Star Wars universe that Twi'lek women are desired by males of all species - and yes, it often really is due to their "naughty" lekku, which can be trained to perform sensual functions. It was used rather disturbingly in A. C. Crispin's novel The Hutt Gambit, where a young Han Solo is (to his chagrin) leered at by an elderly female Twi'lek.
 * 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.
 * A notable storyline in The Avengers had Mantis (human) married to a telepathic alien tree.
 * 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.
 * Interestingly, there are no nerve endings in the brain for registering pain. that means Mallah could do anything he wanted to with the Brain, and he would never feel it.
 * Echiboo (hamster) and Luna-P (pig) in Aoi House. Pretty much par for the course, actually.
 * 2000 AD'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.
 * Disney Comics in general occasionally have mixed-species pairs showing up as background characters in a panel or two.
 * 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, has left Earth and is now living  , where he lives a happy, wholesome family life with his wife and son. Unlike most examples of this trope, the   are not rendered physically attractive or appealing in any way; Hal Jordan instead uses his power  , and is extremely reluctant to return to Earth  , until his wife urges him to help his own people. He only reverts back to his human form after he has already left  , and is quick to return as soon as his business on Earth has been finished
 * Superman and Lois Lane, naturally. His former girlfriends include Lana Lang and the mermaid Lori Lemaris. Of course, seeing as there aren't many Kryptonians left, he doesn't have much of a choice.
 * Supergirl has that problem too, but has had a few odd boyfriends; in addition to Brainiac 5 (mentioned above), she 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.
 * DC once printed an Elseworld story (back when they're still called "Imaginary Stories") where Lois Lane had been killed after Superman settled down and had a daughter with her. At one point, he created a robot duplicate of her, which proved to be all too lifelike. Apparently, Uncanny Valley doesn't faze some people.
 * And let's not forget Johnny Storm and his former wife Lyja. He thought she was human when he married her; she's a Skrull. In the MC-2 Universe they are still married and have a son, Torus.
 * There's a children's comic called Mr. Badger and Mrs. Fox, it's meant as An Aesop about blended families.
 * The Incredible Hulk (gamma-irradiated human) with Jarella (from K'ai) and Caiera (Shadow Person). He had two sons from his relationship with Caiera. And of course with Umar (Dark Dimension native) though that one isn't exactly "romance" from his point of view.
 * In the Howard Chaykin comic American Flagg!, one of Raul the (talking) Cat's favorite TV programs was titled "Interspecies Romances."
 * Cherry Comics: Aliens, bigfoots, dolphins... If it can have sex with a human, Cherry will sleep with it.
 * Crusader Adam of Destine (later simply Adam Destine) and the djinn Elalyth, parents of the Destines in ClanDestine.
 * The North Wind and  from Fables. Bigby and Snow White.
 * Les Legendaires has Gryf, a Jaguarian, being part of a Love Triangle with Shimy, an Elf with Elemental Powers, and Shun-Day, an artificially magically engeneered being created from the arm of a demonical Evil Sorcerer. It also has Dark Jadina, an evil clone of one of the protagonist, being the Dark Mistress of Anathos, a God of Evil;
 * the concept is actually lampshaded in-universe when Shimy asks her mother, Captain Shamira, how she'd react if she was gonna marry a human. Shamira express disconfort with the idea, merely answering her daughter to shut up.
 * Kree champion Captain Mar-Vell seemed to have a thing for this. He had at least three children, all of them have different mothers, and none of said mothers are Kree.
 * Tigra, much like Johnny Storm, had a lover who was a disguised Skrull; in this case, the spy Criti Noll had taken the form of Henry Pym. (It didn't end well.) Their toddler son Charlie his mother's cat-like features with some of his father's reptilian traits.
