* Like many fics, ''[[http://summerlightning.tumblr.com/post/12939130485/ Tower, Tower]]'' pairs Princess Bubblegum (candy person) with Marceline (half-demon vampire), but adds a twist at the very end when [[spoiler:Bubblegum becomes [[CuteGhostGirl a ghost]].]]

* In ''[[https://www.fanfiction.net/s/6061123/1/Oh-My-Goddess-The-Twilight-Hour Oh My Goddess! The Twilight Hour]]'', in addition to the usual Keiichi[=/=]Belldandy, Urd falls in love with a young professor of mythology.
* ''[[https://www.fanfiction.net/s/5273034/1/The_Goddess_and_the_Sky The Goddess and the Sky]]'' replaces Keiichi with Sora, who [[AccidentalMarriage accidentally wishes that Belldandy would marry her]].
* In ''FanFic/AhArchfall'', Lind starts a FriendsWithBenefits relationship with OriginalCharacter Jago which soon blossoms into love, but he's reluctant to marry her due to the MayflyDecemberRomance.

* From [[http://sonamyfan362.deviantart.com/gallery/41694107 this gallery page]], [[http://sonamyfan362.deviantart.com/art/A-New-Life-Era-351466819 A New Life Era]], and [[http://sonamyfan362.deviantart.com/art/Moe-and-BIOS-birthday-party-352810131 Moe and BIOS birthday party]], there is heavy speculation about this between [[spoiler:between Amy Jr. and Moe. The Recovery Part 2 shows there MIGHT be some romantic love between the two. However, they're both very young, and may not be each other's soul mates. For all we know, Bertha might be Moe's soul mate, although The Hacker probably wouldn't be too happy about that.]]

* In ''FanFic/AnAnthemForShelteredBays'', Eren, who is a mermaid in this story, marries Levi,who is still human.
* ''[[http://archiveofourown.org/works/3148466/chapters/6831116 Thicker than Water]]'' is a WholePlotReference to Anime/SpiritedAway which makes Levi the Haku (a river spirit) to Eren's Chihiro.

* Lucia and the first William Adama in ''Fail Better''. She's a goddess, he's a dead human, they meet in the underworld, get married, become the "parents" of generations as ancestor and step-ancestress respectively and "live" happily forever. After some complications.
** Selene and Billy too. Apparently falling in love with humans runs in the family.

* ''FanFic/WakingDream'' has Diva fall in love with [[OriginalCharacter Reeve Roswell]], a human [[spoiler: until she's forced to turn him into a chevalier to save his life]] boy who was the very first human to ever [[BecauseYouWereNiceToMe treat her with any genuine kindness]].

* Most romance fics involving [[GreenSkinnedSpaceBabe Mira]], including ''Fanfic/{{One Hundred Days|BuzzLightyear}}'' (what might well be the TropeCodifier) and ''Fanfic/ForGood''.

* ''Fanfic/CalvinAndHobbesTheSeries'': Hobbes thinks Maria isn't bad looking.

* Chip (chipmunk) and Gadget (mouse) are a popular choice of a couple, ranging from letting the actual romance grow by itself (for example ''[[Fanfic/ChipNoirDalesRescueRangers Fly to the Light]]'') or leaving one or both heartbroken because they CannotSpitItOut and putting one or both through the wringer before their deserved FirstKiss (for example ''Fanfic/RhymeAndReason'', ''Fanfic/OfMiceAndMayhem'', half the ''[[Fanfic/TheMidnightverse Midnightverse]]'').
* Next to Dale & Foxglove and Chip & Gadget, ''Fanfic/TheMidnightverse'' hints at something growing between Sparky (rat) and Lahwhinie[=/=][[MyNaymeIs LaWahini]] (mouse). ''Diamonds In The Desert'' reintroduces Clarice from the ''WesternAnimation/ChipNDale'' cartoon "Two Chips and a Miss" who plays with the two 'munks, but who also is the crush of a mouse. It also introduces a third rat who looks a lot like Rat Capone and Francis (they're brothers in this 'verse), and who hits on Gadget a lot.

* In ''FanFic/AradsStardust'', it's fairly common in Equestria, in part because there are an average of 3 stallions to every 7 mares. Upon hearing this, [[ShipperOnDeck Lana]] immediately figures the best way get Twilight off the fact that she's [[VideoGame/XCOMEnemyUnknown [=XCOM's=] newest test subject]] is to imply that Matt thinks Twilight is cute. Twilight takes it very seriously, and even searches for information about "Human Courting Protocols." Matt is mostly upset how Lana refuses to stop teasing him about it, but there is some ShipTease between the two.
* ''Fanfic/LastChildOfKrypton'': Shinji, who is half-Kryptonian, and Asuka -an human- eventually become a couple.
* In the MegaCrossover ''FanFic/PeaceAndIsolation'', [[WesternAnimation/MyLittlePonyFriendshipIsMagic Luna]] has a crush on Adam, AKA [[TabletopGame/{{Warhammer40000}} the God Emperor of Man]]. It may not be completely one-sided.
* The Review Team has a [[InterspeciesRomance/TheReviewTeam sub-page in development]] because the amount of inter-species couples goes [[UpToEleven THROUGH THE ROOF.]]
* The ''[[Series/BuffyTheVampireSlayer Buffyverse]]'' and ''Franchise/HarryPotter'' CrossOver ''[[https://www.fanfiction.net/s/2547336/1/The-Savior-and-the-Scourge The Savior and the Scourge]]'' has the main pairing of Spike (vampire) and Harry Potter (human wizard) as well as the {{Beta Couple}}s of [[spoiler:Angel (vampire) and Draco (human wizard), Illyria (Demon Goddess[=/=]EldritchAbomination) and Neville (human wizard), and a threesome of Willow (human witch), Lupin, and Oz (werewolves).]]
* Hinted at in ''FanFic/StargateEquestria'' between Daniel Jackson and Twilight Sparkle. Leads to the following exchange with O'Neill (which he quite understandably finds rather [[{{Squick}} unsettling]]):
-->"If both participants are sapient beings, is it really besti —"\\
"Do not finish that sentence, Jackson."
* ''Fanfic/SOE2LoneHeirOfKrypton'': Asuka is half-kryptonian half-human and Shinji is human. Shinji really liked her and Asuka gradually fell in love with him due to Shinji being always there for her. Finally in chapter 19 they got together.
* In ''FanFic/TimeLordsAndTerror'' the Doctor ([[ChickMagnet of course]]) has ShipTease with most of the main six, much of it with Twilight, and Celestia implies Luna develops a crush on him in the [[TimeTravelTenseTrouble future/past]]. He looks like a pony here, but he [[HumanAliens looked like a human]] in his original universe despite being very much not.
** In ''Fanfic/MinesOfDragonMountain'', two Diamond Dogs joke with [[CuteWitch Twilight Sparkle]] about how they wouldn't mind engaging in [[UnusualEuphemism 'Equestrianism']] with her friends [[TheFashionista Rarity]] and [[ShrinkingViolet Fluttershy]]. Unfortunately for them this is just after the BigBad has ponynapped her friends, and Twilight doesn't take it well. [[CurbStompBattle At all]].
* ''WebAnimation/TurnaboutStorm's'' RecursiveFanfiction[=/=]Unofficial {{Novelization}} of the original video series adds this as something of a subplot. For example, some attraction grows both ways between [[Franchise/AceAttorney Phoenix]] and [[WesternAnimation/MyLittlePonyFriendshipIsMagic some of the pony folk]] like Twilight and Fluttershy, and {{Original Character}}s Cruise Control (male pegasus) and Lenora (female griffon) get some ShipTease. According to the RecursiveFanfiction's author, he added those subplots inspired by subtext present in the original series.
* ''[[https://www.fanfiction.net/s/6731833/1/Angels-of-the-Storm Angels of the Storm]]'' a ''Franchise/MassEffect''/''[[TabletopGame/{{Warhammer40000}} Warhammer 40k]]'' crossover, has an eventual hook-up between [[GreenSkinnedSpaceBabe Samara]] and [[SuperSoldier Captain]] [[SpaceMarine Malleus]].
* The ''Series/BuffyTheVampireSlayer''/''ComicBook/PowerGirl'' crossover ''FanFic/OriginStory'' features Alexandra Harris, a Kryptonian, falling in love with Louise Fulford, a human being. They even talk about becoming parents one day.
* ''Fanfic/TalesOfBleachUnrealSociety'' has Raine and [[spoiler:Byakuya]].
* FanFic/AGoddessComesToCall has two examples of goddess/human ([[BubblegumCrisis Linna]] and [[Manga/AhMyGoddess Belldandy]], Priss and Urd) and one of human/demon (Sylia and Mara).
* ''[[https://www.fanfiction.net/s/11144592/1/Lum-Sum-Purple Lum Sum Purple]]'' revolves around [[RanmaHalf Shampoo]] replacing [[Manga/UruseiYatsura Ataru]] in that fateful game of Tag, and ending up married to Lum. Also, OriginalCharacter Perfume (Shampoo's cousin) accidentally wakes up Kurama and becomes engaged to her, as well as developing feelings for Benten.
* The WesternAnimation/ScoobyDoo [=/=] Anime/{{Naruto}} fanfic [[https://www.fanfiction.net/s/6117094/1/Ghoul-Instructor-Naruto Ghoul Instructor Naruto]] revolves around Naruto becoming [[WesternAnimation/ScoobyDooAndTheGhoulSchool the gym teacher at Grimwood Academy]], and gaining an UnwantedHarem composed of the Grimwood girls and Miss Grimwood's [[OriginalCharacter niece]] [[CuteWitch Gem]]. Also, the sexual education teacher is [[HornyDevils a succubus]] (the aunt of [[Anime/RosarioToVampire Kurumu]]) who likes flirting with him.
* ''[[http://archiveofourown.org/works/975144 Quandry]]'' reveals that [[Anime/TenchiMuyo Washu's husband]] who abandoned her and took their son with him was, in fact, [[Series/StarTrekTheNextGeneration a Q]] who had been forced to do so by the Q continuum.
* The ''Franchise/{{Metroid}}''-''Franchise/{{Kamen Rider}}'' crossover fic, ''[[https://www.fanfiction.net/s/11772125/1/Metroid-Kamen-Rider-Generations-Full-Series Metroid: Kamen Rider Generations]]'' has Samus Aran, who is of Chozo heritage and with Metroid DNA, falls in love with Armored Rider Ryugen, Mitsuzane Kureshima, who is in fact human.
* ''[[https://www.fanfiction.net/s/11167657/1/Love-and-Robots Love and Robots]]'' has [[Franchise/{{Transformers}} Dinobot]][=/=][[WesternAnimation/StevenUniverse Gem]], as Grimlock falls in love with Garnet (only to learn that she's a fusion who isn't interested in adding a third to the relationship), then Jasper (who he marries, only to learn that she used to be married to Megatron).
* ''FanFic/TheBridge'' has [[spoiler: Aria Blaze and Monster X]] as a subversion. While they are two very different species, both already two types of HybridMonster, they were both in human form when they met and had a majority of their interactions.
* Zigzagged in ''Fanfic/TheWheelAndTheButterflySaga'' with Dan and Pinkie, since Pinkie is technically stuck as a human when they first start dating, [[spoiler: but played straight when she is turned back into a pony.]]
* In ''[[https://www.fanfiction.net/s/1338658/1/Onegai-Megami-Sama Onegai, Megami-Sama!]]'', [[Anime/PleaseTeacher Matagu]] [[Anime/PleaseTwins Shido]] accidentally summons [[Manga/AhMyGoddess Peorth]], and wishes for her to be his girlfriend.
* ''[[https://www.fanfiction.net/s/1901131/1/For-the-love-of-a-Goddess For the Love of a Goddess]]'' is a Series/BuffyTheVampireSlayer and Manga/AhMyGoddess crossover, where Xander replaces Keiichi as the one who accidentally summons Belldandy and wishes for her to stay with him forever.
* In ''FanFic/RosarioToKiva'', [[Series/KamenRiderKiva a teenage Wataru]] enrolls in [[Manga/RosarioToVampire Youkai Academy]], and replaces Tsukune as the one who wins Moka's heart (and that of the other girls). MarryThemAll is discussed (due to Wataru being Fangire royalty), [[spoiler: but he ultimately marries Moka, although not before getting Mizore pregnant like he promised her]].
* In ''Series/Supergirl2015''/''Series/TheFlash2014'' crossover ''Fanfic/CallMeKara'', [[Comicbook/{{Supergirl}} Kara Danvers]] -a Kryptonian- and [[Franchise/TheFlash Barry Allen]] -a human- fall in love and have a daughter.

[[AC: ''Manga/DailyLifeWithMonsterGirl'']]
* In ''[[http://archiveofourown.org/works/7390630/chapters/16787725?view_adult=true Daily Odd Life with Monster Girls]]'', dragon-girl Kishimura is in a relationship with the human Erika, while the protagonist Shirou is the love interest of Naki the zombie, Yukiko the yeti and Eleanor the long-legged Aachne.

[[AC: ''Manga/DeathNote'']]
* Many Light/Ryuk fics, thanks to heaps of in-series NoYay.
** In the ([[MissingEpisode since deleted]]) fic ''[[FanFic/SevenMinutesInHell 7 Minutes In Hell]]'', [[TheBeard Misa]] tries to force Light to put out for her and forces Light (and Ryuk) to play [[TenMinutesInTheCloset 7 Minutes In Heaven]]. But its Light and Ryuk [[ComedicSociopathy who end up getting shoved into the dark closet together]] where they discover they ''really'' [[ClosetKey like it]] and [[CoitusEnsues end up together]], leaving Misa heartbroken.
** In ''FanFic/ACharmedLife'' Light determines he needs to be closer to Ryuk to avoid the Shinigami getting bored and killing him. He becomes closer to Ryuk than anticipated when he discovers Ryuk has a crush on him.
** ''[[http://archiveofourown.org/works/861530 Dirty Entertainment]]'' where Ryuk fantasizes about using Light in other ways.
** ''[[https://www.fanfiction.net/s/4738898/1/ Everyone Deserves A Christmas Gift]]'' is an established relationship Ryuk/Light fic (though it mentions that Ryuk shapeshifts into a {{Bishonen}} humanoid form when they're together.) Light gets Ryuk a Christmas present and in return [[spoiler:[[DisproportionateReward Ryuk grants him Godhood.]]]]
** In ''Fanfic/ForbiddenFruit'' [[TheVamp Light]] seduces Ryuk.
** ''[[http://archiveofourown.org/works/153314/chapters/220084 Joined]]'', a Light/Ryuk fic where Ryuk can assume a {{Bishonen}} humanoid form [[{{Narcissist}} that resembles a dark-haired Light]] and in this form he successfully seduces Light into having a bit of fun with him.
** In ''[[https://www.fanfiction.net/s/3941333/1/ Legally Damned]]'' Light agrees to become Ryuk's boyfriend and [[IChooseToStay eventually a Shinigami and moves with him to the Shinigami realm]] in order to get away from L and the police.
** In ''[[http://archiveofourown.org/works/427645/chapters/719500 The Shinigami Wing Deal]]'' Ryuk makes Light his SexSlave.
** In ''[[http://archiveofourown.org/works/616971/chapters/1112940 To Feel Alive]]'' Ryuk is [[InLoveWithYourCarnage in love with Light's carnage]] and is a bit of a {{Yandere}} for him as well.
** In ''[[https://www.fanfiction.net/s/9596737/1/The-Unwritten-Rule The Unwritten Rule]]'' Light offers to have sex with Ryuk [[SexForServices in exchange]] for the Shinigami eyes.
** In ''[[https://www.fanfiction.net/s/4024213/1/ What Were You Thinking?]]'' Ryuk and Light resolve their sexual tension.
* ''FanFic/{{Addiction}}'' is an [[AlternateUniverseFic AU]] Light/L fic where Light becomes a Shinigami.
* In ''FanFic/BetterShinigami'' Rem is in love with Misa and [[TheVamp Misa exploits this]]--flirting with Rem in an attempt to get [[LoveMartyr Rem to kill herself.]]
* In ''[[http://atlantagirl.deviantart.com/art/A-Day-With-a-Loving-Shinigami-361953640 A Day With A Loving Shinigami]]'' Rem and Misa go out on a date.
* In ''FanFic/DeathAndHisShadow'', L is a Psychopomp who wants to take Raito's soul after he dies... but when Raito doesn't die, he ends up falling in love with his would-be victim.
* ''Fanfic/AndTheStoryContinues'' has [[OriginalCharacter Erin]] and Umbra, a shinigami. Their relationship deconstructs the trope--although they do have genuine feelings for one another, Erin feels disgusted with herself and fears being rejected by what friends she still has because of the relationship. Plus their moral and cultural differences get in the way (for example, he sees nothing wrong with murder whereas she's an AllLovingHero who believes ThouShaltNotKill). To further complicate matters, Umbra [[spoiler:[[AndThenJohnWasAZombie is actually L reincarnated after his death]] [[Fanfic/StoryOfTheCentury in the prequel.]] Presumably the transformation is due to his usage of the notebook, and because she feels responsible for him, Erin can't find it in her to break away from him]].
** Subverted, however, with Misa and Lumen. Lumen [[spoiler: likewise is Light's reincarnation, but not only does he still have no feelings for her--except condescending scorn--he doesn't even remember who she is. Misa, who still has feelings for Light and has been grieving for his death all along, definitively crosses the DespairEventHorizon upon figuring all this out]].

* ''[[https://www.fanfiction.net/s/442364/1/As-a-Flower-to-the-Light As a Flower to the Light]]'' pairs [[Anime/DigimonAdventure02 Hikari]] with a Rosemon.
* In ''[[https://www.fanfiction.net/s/822944/1/The-Stepmother-s-Wishes The Stepmother's Wishes]]'', [[Anime/DigimonTamers Juri]] falls in love with Leomon.

* ''[[Fanfic/TwiceUponAnAge All This Sh*t is Twice as Weird]]'' has Mahanon (Dalish elf) and Cassandra (human noblewoman). There's also, in the backstory of the setting, Darrian (Dalish elf) and Morrigan (human mage), as well as a couple of the pairings carried over from [[VideoGame/DragonAgeInquisition the source material]].
* ''FanFic/WalkingInCircles'' has Evelyn (ex-noble human mage) and Solas (ancient Elven god). Between the two of them, Solas was the one who pays more attention to the nature of their relationship as he had to overcome the feeling of betrayal toward his brethren by falling in love with a ''shemlen'' before having the courage to confess his love to her.

* Happened in ''FanFic/TheTaintedGrimoire''. [[spoiler:Kanin]] is the result of one of these.

* ''Fanfic/{{Deserving}}'' has Crabbe shagging a house-elf, thankfully off-screen.

* The fanfic writer superstarultra is believed to be the first person on Website/FanFictionDotNet, and possibly the first person period, to pair Fujiwara and Kuyou together as a [[EvenEvilHasLovedOnes Villain Couple]]. (For those unfamiliar with the source material, Fujiwara is a human and Kuyou is a HumanoidAbomination. Yeah, superstarultra is [[CrackFic that kind of writer]].) Since he created the pairing, it has become something of a RunningGag in ''FanFic/YouGotHaruhiRolled'', several chapters of which have Kuyou behaving as an AbhorrentAdmirer to Fujiwara. Aside from this, one arc which was explicitly an AlternateUniverse had the Anti-SOS Brigade as members of the British Royal Navy; as [[SubvertedTrope both are human]] in this arc, Fujiwara reciprocates. [[DoubleSubversion Only for Kuyou to be transformed into a kraken before the story starts.]] (Fujiwara ''still'' reciprocates.)

* In ''[[https://www.fanfiction.net/s/10012440/1/Arnold-s-Vampire Arnold's Vampire]]'', Helga is a {{Dhampyr}} who ends up bonded to Arnold after she drinks his blood, and ends up falling in love with him.

* ''[[https://www.fanfiction.net/s/2814211/1/Ah-My-Ronness Ah My Ronness]]'' turns the [[OfficialCouple Kim/Ron]] pairing into this, as Ron is made in a god ala [[Manga/AhMyGoddess Belldandy]].

[[AC: ''WesternAnimation/KungFuPanda'']]
* ''Fanfic/TheVow'' is about the tragic love between Lord Shen (peacock) and Lady Lianne (swan). [[spoiler:They have in the epilogue a child that's a peacock with some traits from a swan.]] There is also affection born between Zhan the Wolf Boss ([[CaptainObvious wolf]]) and Jade (dhole).

[[AC: ''WesternAnimation/TheLionKing'']]
* ''[[https://www.fanfiction.net/s/5668840/17/Before-and-Beyond-the-Beginning Before And Beyond The Beginning]]'' is a PerspectiveFlip focusing on the hyenas that includes a Scar/Shenzi pairing. It explains that even though Shenzi finds the idea utterly revolting, exactly why ''Scar'' (in his growing insanity) might start thinking it over time.
--> '''Scar:''' That’s what I like about you, Shenzi. All Sarabi and Zazu ever do is whine, whine, whine about every little complication, as if they can't do a single thing by themselves. You never bring me any bad news.

[[AC: ''Franchise/MarvelCinematicUniverse'']]
* ''[[http://archiveofourown.org/works/650455/chapters/1183584 Prince of Asgard]]'' has Loki ([[spoiler: Jotun]]) and Tony Stark (human).
* ''[[https://www.fanfiction.net/s/10744007/1/Beyond-Death Beyond Death]]'' has ComicBook/{{Thanos}} crash-land on Earth and meet a young woman, whom he temporarily moves in with. While he plans to kill her once he's recovered his strength (the only reason he doesn't is because she gets fused with the Tessarect), he ends up falling in love with her and vice-versa.

* The ''Fanfic/{{Uplifted}}'' trilogy has Joachim Hoch and Hanala Jarva vas Devoas, an SS officer and Quarian Captain, and the affair between [[spoiler:Erwin Rommel and Admiral Utala Falan]]. In the next series, it's revealed that although some mxed species couples try to make it work, few relationships last. Even the Jarva-Hoch family is strained with the difficulties of mixed species family, with John Hoch's newly discovered daughter flat out ''rejecting'' any kinship the quarian side of her father's family has. [[spoiler:Which is understandable considering she is noted unrepentant quarian killing Commando Otto Skorzeny's Granddaughter and raised by an equally xenophobic mother]]
* Interspecies Romance is the norm in ''Mass Effect'', so the fanfic ''[[Fanfic/GhostghostIknowyoulivewithinme Ghost, Ghost, I Know You Live Within Me]]'' brought this UpToEleven by having Turian/Human ''ghost''.
* The [[EverythingsBetterWithDinosaurs sentient dinosaurs]] in ''FanFic/MesozoicEffect'' are firm believers in this, which is unsurprising considering the sheer number of sapient dinosaur species. Children from such parings are normally DesignerBabies created by the dinosaurs' extremely advanced genetic engineering. When they awake from [[HumanPopsicle cryonic suspension]], the dinosaurs see no particular reason why the humans who now control Earth wouldn't also make suitable mates. This eventually leads to several [[HotSkittyOnWailordAction anatomically confusing]] pairings. For example, Ashley Williams' mother is revealed to be a [[PrehistoricLifeSauropods Cetiosaurus]], while her grandmother is a ''[[TyrannosaurusRex T-Rex]]''. Both her father and grandfather are human. [[spoiler: Careful reading reveals reference to Ashley's ''egg'', suggesting that all this mixed parentage has had a serious impact on her eventual species.]]

* In ''Fanfic/AngelasPetMonster'' Randall falls for Lucille, a saluki. [[spoiler:They even [[HotSkittyOnWailordAction have puppies]].]]
* In ''Fanfic/LostThenFoundButNotHealed'' a human named Danielle Demarsh falls in love with Randall Boggs.

* The fandom is filled with ''tons'' of human/pony romance stories, many of them the [[TrappedInTVLand "human male from the real world enters Equestria]], falls in love with a main character" variety, if not an outright SelfInsertFic. A common joke about the fandom is that they're all into [[BestialityIsDepraved bestiality]].
** They're so common ''[[http://www.fimfiction.net/story/86723/a-night-with-lyra A Night With Lyra]]'' was able to successfully [[spoiler:MetaTwist the reader by having this ''not'' be the case]]. Just check the comments: every single one points this out.
** Teased in ''FanFic/TheCommanderOfShepherds'' between (female) Commander Shepard and Luna. The potential pony/human squick factor is lessened by Luna being a shapeshifter.
** ''[[http://www.fimfiction.net/story/100083/1/blissful-dream/blissful-dream Blissful Dream]]'' is a love story about a pony and a human.
** ''Twi and Me'' has human male and female pony (Twilight Sparkle).
** ''Fanfic/{{Xenophilia}}'' involves Rainbow Dash getting a human boyfriend. Despite being a {{Lemon}} the fic spends a fair amount of time discussing differences between humans and ponies as come to sex and gender relations. It mostly treats the human [[HumansThroughAlienEyes as the alien partner]] (talking about his ExoticEquipment, for instance).
** ''FanFic/SophisticationAndBetrayal'' involves one between the unnamed human protagonist and Rarity.
** ''FanFic/TheMixedUpLifeOfBrad'' has this between Brad the human, and Twilight the unicorn. Subverted a bit, as Brad fell in love with Twilight when she was transformed into a human, and now that she's back in her pony form he finds her physical appearance unappealing. It is noted that they cannot ever be truly happy together, being so different from each other.
** The same author's ''Fanfic/AMightyDemonSlayerGroomsSomePonies'' gives Danny (from G1 ''Franchise/MyLittlePony''), an eleven-year-old human, a crush on Surprise the pegasus (who is an adult at the time by pony standards). Nothing comes out of it, and he still has bad memories years later. It's hinted that it's all because he was still a young kid at the time, confused by his budding sexuality.
** ''[[http://www.fimfiction.net/story/170866/mating-customs-of-species-equus-parvus Mating Customs of Species Equus parvus]]'' explores this a bit: Humans have a tendency for seeking exotic partners, an evolutionary trait which used to help them reduce inbreeding by encouraging them to find partners in other communities. As a side-effect, it makes them prone to InterspeciesRomance with other sapient races--which, however, do not share this trait, so such infatuations are pretty much always one-sided (and result in the unlucky human suitor laughed off).
** ''FanFic/ArddunLleuad'' and its sequel, ''Chwe Goleadau'', has the romance between the human protagonist and Luna as one of its main themes. They have some anguish over just ''how'' far are they going to take their relationship. At the very end, [[spoiler:the point becomes moot, as the protagonist gets castrated by the villain.]]
** In ''Fanfic/AllAmericanGirl'', there are close relations between Earth and Equestria, and pony-human relationships or couples are not unheard of--the protagonist herself is a pony married to a human. That said, the setting also has temporary species-transformation magic available for the spouses, allowing such couples to actually have children together.
** ''Fanfic/AVoiceAmongTheStrangers'' has the human protagonist Jessica realising that [[spoiler:Iron Will, a minotaur]] is attracted to her, and [[DefiedTrope immediately turns him down]]. Played straight in later chapters with [[spoiler: Bastion (pegasus) and Minder (changeling).]]
** In ''Fanfic/EquestriasFirstHuman'', a socially awkward teenager falls in love with Fluttershy. [[spoiler: It is averted later on when his spirit is brought back to Equestria, he chooses to be reborn as a pony, since he could love Fluttershy more easily that way]].
** Averted in ''FanFic/TheRiseOfDarthVulcan''. Due to changeling custom and instinct, since Vulcan beat Chrysalis in a fight, she becomes enamored with, and dedicated to him. Vulcan, however, is completely disgusted with both the concept of this trope, and Chrysalis herself. So, he uses her for information and experience, but refuses all her advances.
* In ''Fanfic/SummerDaysAndEveningFlames'', Gilda (a griffin) eventually starts dating her guard captain Iron Bulwark (a pony). She's justifiably worried that dating him could make others look down on him, considering his best friend is very racist to griffins.
* [[http://www.fimfiction.net/user/kalash93 Kalash93]] wrote ''[[http://www.fimfiction.net/story/81159/1/racer-and-the-geek/predawn Racer And The Geek]]'', which makes Zecora one of the protagonist's primary love interests, if not his main one, and ''[[http://www.fimfiction.net/story/88520/1/welcome-to-the-brothel/das-laufhaus Welcome to the Brothel]]'' and ''[[http://www.fimfiction.net/story/106068/1/relax/intimacy Relax]]'', both about a pony soldier and a zebra sex worker. This is only a borderline example, however, as canon isn't really clear whether zebras are a separate ''species'' to unicorns, pegasi and earth ponies or just another ethnic group.
* A pair of recurring background characters in ''FanFic/CadenceInAMinor'' are a stallion/griffon couple, who are also soldiers on the opposite side of a tense border. Despite everything stacked against them, they make a pretty cute couple, all told.
* The Blog/ReadingRainbowverse has the typical Gilda/pony romance... but mixes it up by having a cat crush on Gilda too. Not an anthropomorphic cat... a normal housecat.
* The ''FanFic/PonyPOVSeries'':
** Strife, the Draconequus of Natural Selection, is HappilyMarried to Mortis, the Alicorn of Death, and they have kids.
** Anarchy, the Draconequus of Freedom and Rebellion, is married to Nightmare Legion, an Alicorn formed from millions of Shadows of Existence.
** [[BadFuture Dark World]]!Derpy has feelings for [[Series/DoctorWho the Doctor]], which is part of her motivation for wanting to destroy the Valeyard and force him to regenerate back into the Doctor. [[spoiler:She succeeds and ends up marrying him after [[BiggerBad Nightmare Eclipse's]] defeat, though he's using a Fob Watch.]]
** Dark World!Rarity and Dark World!Spike become an OfficialCouple and [[spoiler:become HappilyMarried after defeating Eclipse. Rarity also becomes an Alicorn.]]
** [[spoiler:Celestia and Discord]] were once in love, but the latter's {{Sociopath}}y and sadism ended that.
** [[spoiler:Minuette and Captive Audience]], as the former is actually a Time Lord. Though it's a bit ambiguous after [[spoiler:Minuette destroys [[EnemyWithin the Master]]]] if she's still one or not.
* TD ends up in one with Cheerilee in the main continuity of ''FanFic/TheNonBronyverse''. In the alternative-continuity AU story where he gets accidentally turned into an alicorn, he eventually strikes one up with Celestia.
* Rarity and an aged-up Spike in Fanfic/TheDearSweetieBelleContinuity, as far as they know the first pony/dragon couple in Equestria's history.
* DiscussedTrope in ''Fanfic/RomanceAndTheFateOfEquestria''. Iron Will tries to take his friendship with Fluttershy to the next level; Fluttershy politely declines and later consults her friends as to their thoughts about interspecies dating. When they all view it as a non-issue, this leads Fluttershy to think she's [[FantasticRacism bigoted for only being attracted to ponies]]. When it's further explained that this is because she wants to have children, Rainbow Dash labels her a "breeder", and assures her that it's perfectly normal.
* ''Fanfic/JustBeforeTheDawn'' features one between Celestia and Tercio.
* ''Fanfic/ZestarAppleFlambe'' involves Spike and Apple Bloom falling in love with other, and having a child together.
* ''FanFic/BrideOfDiscord'' centers around Fluttershy and Discord. It is also hinted, that Discord had unresolved feelings for Celestia.
** There is also a major subplot between Spike,[[note]] Who like in canon, has a crush on Rarity that does not seem to be reciprocated[[/note]] Rarity, and ''Applejack'' of all ponies. [[spoiler: Applejack and Spike end up together.]] This is LampShaded, when Spike points out that Discord and Fluttershy aren't even the same species, only for Applejack to point out the hypocrisy.
** The sequel also has one between Discord and Fluttershy's daughter Screwball and Mothball, who is a changeling.
** Yet another sequel in the series, has one between Iron Will and a changeling named Bellatrix.

* In ''FanFic/ABatInStorybrooke'', [[Disney/TheGreatMouseDetective Fidget the Bat]] was in love with Isabella, a human princess, and the two were engaged to be married before she accidentally got killed.

* A [[http://anime.adultfanfiction.net/story.php?no=600041040 fanfic]] pairing an AuthorAvatar and his Gardevoir. Smut ensues.
* [[https://www.fanfiction.net/s/9931728/1/Boundless-Love-The-Tale-Of-Athena Another Gardevoir related fanfic.]] This one is about a boy growing up with a female Ralts. Due to some genetics, the Ralts, then Kirlia, becomes more and more human as she spends time with the boy and their relationships develops.
* Subverted [[http://www.furaffinity.net/view/11568972/ here]]. It opens with a great big monologue about human and pokemon being intimate -- even having offspring -- is supposedly very common. The titular character has had two inter-species relationships: One with Tera, a pelipper, the other with Henry, a human. [[spoiler:Neither of which was intimate. Tera [[InterspeciesAdoption just wants to be a dad]], while she Henry just gets a kick out of tricking people into thinking they're a couple.]]
* In ''[[https://www.fanfiction.net/s/9857038/1/Revisit Revisit]]'', Ash becomes romantically involved with Arceus.
* Pairing Ash with the Latias from the [[Anime/PokemonHeroes fifth movie]] is a somewhat popular ship, known as "[=AltoShipping=]". The better fics in this category will point out that this kind of thing is frowned upon, and have the characters take a while to work through it. [[SturgeonsLaw The others?]] [[PornWithoutPlot Not so much.]]

* ''Fanfic/AForceOfFour'': Kara –a Kryptonian- is dating Andrew Vinson –a human-. And Lyta –half human, half Amazon- and Hector Hall –Thanagarian- are lovers.

[[AC: ''WesternAnimation/ReadyJetGo'']]
* In ''Fanfic/TheDangersOfAlienHumanInteraction'', Jet, an alien, dates Sean, a human.

* ''Fanfic/OldWest'': The canonical example of [[BetaCouple Rango and Beans]], with him being a chameleon and her being a desert iguana. While they're both lizards, their species are quite different. The main focus is on a similar example between [[{{Outlaw}} Rattlesnake Jake]] and [[DeterminedHomesteader Grace Glossy]], who are a [[CaptainObvious rattlesnake]] and a glossy snake, respectively. Also, Grace used to have this kind of a relationship with the father of her son Teddy, Benjamin Hares, who's a gopher snake.

[[AC: RealPersonFic]]
* Very one-sided in ''Fanfic/WithStringsAttached''. Shag, a “lizardy, birdy” alien, is clearly in love with the (usually human) four, but it's strictly from a distance, and they certainly do not love her.

[[AC: ''Manga/SgtFrog'']]
* ''FanFic/YinAndYangSeries'': Let's see... There's Mahihi and Daisy, Romama and Aya, Fujuju and Botan, Rokiki and Mora, Haruki and Lavi, Porara and Mois, and even Kirere and Hiroshi, for one story.

* A currently unfinished fanfic series which pairs up the characters of Patricia (a [[EverythingsBetterWithPlatypi platypus]]) and Peri (not known for sure, mostly assumed to be [[MixAndMatchCritters a cuttlefish/squirrel hybrid]]).

* The Kirk (human) and Spock (half-human half-Vulcan) pairing from many a fanfiction deserves mention by being the {{Trope Namer|s}} for SlashFic.
** The fic ''Fanfic/WrittenInTheStars'' has Kirk genderswapped, and ends up with Spock in ''four different realities''. Each time resulting in a HalfHumanHybrid daughter.
* ''Fanfic/{{Bait and Switch|STO}}'' has one between a couple of {{Mauve Shirt}}s from the USS ''Bajor's'' security department, Ensign Kate [=McMillan=] (human female) and Lieutenant (JG) K'lak (Klingon male). They're stated to have been in an on-again, off-again relationship for the last couple of months, but decide to go exclusive in chapter nine.
* In ''Fanfic/RedFireRedPlanet'' Lieutenant Commander Brokosh, a Lethean mercenary, is HappilyMarried to Klingon noblewoman Ba'woV, daughter of N'Gara, of the House of Chel'toK, a Klingon. Brokosh signed with the Klingon Defense Force when their son was conceived, since Chel'toK is fairly {{impoverished|Patrician}}.
* ''Fanfic/FromBajorToTheBlack'' has Kanril Eleya, a Bajoran, date a human Starfleet Academy cadet exclusively for about a year, to the point of her starting to talk about Bajoran betrothal rituals. This ends badly when Jerrod Dalton is offered early graduation and skips town for the USS ''Planck'' in the middle of the night.
* ''Fanfic/RemembranceOfTheFallen'' has Tiana Lanstar visit the gravesite of her deceased wife Sobaru, a Bajoran.

While their relationship starts as InterspeciesFriendship, that might change (the fanfic ''is'' in the Romance genre, after all).
* Between Greg (a human) and Blue (a vampire) in ''Fanfic/IllMetByMoonlight''.

* In ''[[http://archiveofourown.org/works/10084883/chapters/22473572 The Rose]]'', Luigi (a human) and Prince Peasley (a Bean person) fall in love with each other.

* There are many fanfics where Dean falls in love with Castiel. [[https://www.fanfiction.net//s/5147405/1/In-the-Wake-of-Angels This]] is one of them.

* Klein (Salamander) and Alicia (Cait Sith) have something going on after his RescueRomance during Act 1 in ''Fanfic/FairyDanceOfDeath''.

* In one 4chan copypasta fic King Arthur in a PeggySue scenario decides that he's better off in making [[AbhorrentAdmirer that squirrel]] (who actually loved him and he has Merlin change into a human form) his Queen instead of [[YourCheatingHeart Guinevere.]]

* Fanfiction writer [[https://www.fanfiction.net/u/1845915/Mikell Mikell]] has written a series of fics (''[[http://www.fanfiction.net/s/5249468/1/Mikey_In_Love Mikey In Love]]'', ''[[http://www.fanfiction.net/s/5330168/1/Raph_Ann Raph and Ann]]'',
''[[http://www.fanfiction.net/s/5399991/1/Donatello_Lost Donatello Lost]]'' and ''[[http://www.fanfiction.net/s/5466190/1/Leonardos_Angel Leonardo's Angel]]'') in which each of the Turtles falls in love with a human women. The continuation, ''[[https://www.fanfiction.net/s/6697098/1/Splintered-Hearts Splintered Hearts]]'', hints at a DecemberDecemberRomance between Splinter and the aunt of one of the OriginalCharacters.

* ''[[https://www.fanfiction.net/s/4138412/1/Sound-of-Pulling-Heaven-Down Sound of Pulling Heaven Down]]'' has the OfficialCouple of Simon and Nia, except here Nia is an [[EldritchAbomination Anti-Spiral]]. In typical ''Gurren Lagann'' fashion, it barely impedes them at all.

* In ''[[https://archiveofourown.org/works/3749425 something rich and strange]]'', Tintin is a merman who was accidentally fished out of the sea by Captain Haddock's crew, and falls in love with Haddock while recovering from the injuries he received when he was caught.

* ''FanFic/AFarGreenCountry'' has Elden, mortal man, and Nellas, female elf, unless SheIsNotMyGirlfriend.
* ''FanFic/TimeWillTell'' has a romance between Jorryn (the woman from America) and one of the hobbits, but it takes a long time to develop.
* ''FanFic/WorldsApart'' has a dwarf with elf romance.
* There are [[http://archiveofourown.org/tags/Bilbo%20Baggins*s*Thorin%20Oakenshield/works numerous]] [[https://www.fanfiction.net/book/Hobbit/?&srt=1&g1=2&lan=1&r=10&c2=75054&c3=89105 stories]] pairing Bilbo (hobbit) with Thorin (dwarf).
* ''FanFic/WaltDisneyPresentsTheLordOfTheRings'' has Frodo, a hobbit, and Arwen, an elf, fall in love with each other.

* ''FanFic/MaidensIllusionaryFuneral'' chronicles the DoomedByCanon love between Yuyuko (human, later [[CuteGhostGirl ghost]]) and Yukari ([[EldritchAbomination a mass of darkness and eyes]] [[AFormYouAreComfortableWith in the shape of a human]]). Later chapters reveal that Youki ([[HalfHumanHybrid half-ghost]]) was also in love with Yuyuko, but it never went anywhere.
* ''[[https://danbooru.donmai.us/pools/677 Night Sparrow Love]]'' has Mokou ({{immortal|ity}} human) and Mystia ([[LittleBitBeastly sparrow youkai]]) in love with the other but so hopelessly TwiceShy they CanNotSpitItOut until the very end.
* Not quite "romance", but ''FanFic/ImperfectMetamorphosis'' depicts Yuuka ([[spoiler:a weakened [[Franchise/CthulhuMythos Outer God]]]]) as a DepravedBisexual who lusts after anyone she can get her hands on. [[LittleBitBeastly Wriggle]] is heavily implied to have been her pet for a while, and one chapter ends with poor [[AnimateInanimateObject Kogasa]] in her grasp.
* The FlashForward comics of ''Webcomic/TouhouNekokayou'' depict Marisa (human) and Alice (WitchSpecies) as married with [[HasTwoMommies two daughters]].
* ''[[http://archiveofourown.org/works/3210860 Incendiary]]'' takes the CrackPairing of Utsuho ([[LittleBitBeastly raven or crow]], [[LostInTranslation depending on the translation]]) and Reimu (human) and manages to make it plausible.

* Several fanfics pair Starscream with [[Anime/TransformersArmada Alexis]] - [[https://www.fanfiction.net/s/5070772/1/Crosswinds here's one such example]].
* In ''[[https://www.fanfiction.net/s/7391077/1/Beaten-Broken-and-Scarred Beaten, Broken and Scarred]]'', in addition to Starscream[=/=]Alexis, we have Carly[=/=]Soundwave and Jazz[=/=]Maggie.

* In ''[[https://www.fanfiction.net/s/7430603/1/Swarm Swarm]]'', [[WesternAnimation/TransformersAnimated Wasp]] is a hornet who falls in love with Bumblebee the honeybee (Bumblebee being a nickname he has due to his klutziness).

* Multiple mentioned in ''Fanfic/BeautyOfTheBeast'', back in the Golden Age of Cybertron. The two important to the series are June and [[spoiler: Megatron]] and Miko and Bumblebee.

* ''FanFic/ForbidenFruitTheTempationOfEdwardCullen'', on top of the human/vampire pairings, features Jasper Cullen and a human guy he picked up in a bar having a threesome with a talking panda. Yes, you read that right.

[[AC:''TabletopGame/{{Warhammer 40000}}'']]
* ''[[http://1d4chan.org/wiki/Story:Love_Can_Bloom Love Can Bloom]]'', an unfinished fic from the /tg/ board at Website/FourChan in which the [[SpaceElves Eldar]] Farseer Taldeer from ''VideoGame/DawnOfWar'' and a [[ColdSniper Vindicare Assassin]] named LIIVI meet on the battlefield and eventually fall in love. Later fics spun off from LCB would introduce their [[HalfHumanHybrid daughter Lofn]]. A self-admitted GuiltyPleasure by its fans, as such a thing is impossible for [[FantasticRacism innumerable]] [[ArtisticLicenseBiology reasons]]. What makes this particular fic notable is that Creator/GamesWorkshop, 40K's parent company, [[AscendedFanon dropped a couple of acknowledgements to it]] (a pic of a Vindicare watching a Farseer and a quote attributed to LIIVI) in ''TabletopGame/DarkHeresy'' sourcebooks.
** A spin-off ''[[http://1d4chan.org/wiki/Love_Can_BLAM Love Can Blam]]'' ('''NOTE''': {{NSFW}}) features an encounter between a guardsman deserter and a female [[TheGreys Tau]] medic that quickly goes from IntimateHealing right into full-blown [[CatchPhrase heresy]]. [[spoiler:As you may have already guessed from the title, [[DownerEnding it doesn't end well for them]]]].
* ''[[http://1d4chan.org/wiki/Gav_and_Bob Gav and Bob]]'' has an Ogryn named Gav fall in love with a human woman. [[spoiler:Being 40K, [[BittersweetEnding it doesn't end well]].]]

* ''[[http://www.fanfiction.net/s/4235229/1/Sirens_of_Azeroth The Sirens of Azeroth]]'' suggests that the many species of Azeroth don't have a huge amount of trouble with, at least, casual interspecies romance/intercourse, demonstrating among others a [[OurDwarvesAreAllTheSame Dwarf]]/Draenei (seven-foot faun-like blue alien) relationship, a Troll/Blood elf lesbian couple with an open relationship, and a pair of tiny gnomes talking about how their favorite types of 'men' are Tauren ([[HotSkittyOnWailordAction huge]] [[ALoadOfBull minotaurs]]), though they could just be making that up.

* In ''Fanfic/WithThisRing'', Ferdinand the minotaur chef at the Themysciran Embassy has a relationship with Leslie Anderson. There's also M'gann and Kon, but that was canon already.

* ''FanFic/ShadowchasersSeries'' has lots, given the FantasyKitchenSink setting:
** The original fic has Gears (human) and Mistle (dryad).
** In ''Fanfic/ShadowchasersRisenNemesis'', Kyon (were-ermine) has a crush on Ace (human) which is not reciprocated. In ''Fanfic/ShadowchasersTournamentOfShadows'' Ace enters [[BiTheWay a relationship with Kenshin]] (no verified species, but has been compared to a {{Yokai}}.)
** Another LGBT example in ''Fanfic/ShadowchasersBackwater'' with Fayte (vampire, former human) and Tsuki (succubus). Also in Backwater, Tsubasa (human) and Hebi-Na (ophidia).
** Anther human-ophidia paring is in Damien and his now-former girlfriend in ''Fanfic/ShadowchasersCityOfAngels'' (clearly, SnakesAreSexy in this setting)

[[AC:''[[http://tvtropes.org/pmwiki/pmwiki.php/Disney/Zootopia Zootopia]]'']]
* Zootopia/0 (still in production) introduced one of its first characters, Hazel Dodge, as the skunk who contributed to the famous rug. Though neither describes their relationship as romantic, Nick does concede that they were [[http://www.furaffinity.net/view/20895546/ "Close enough to let her shave my butt."]]
** Nick: "Oh, um... (nervous grin) Did I mention there's also a fox butt-rug somewhere out there?"
*** [[http://www.furaffinity.net/view/21861790/ That's not all he did to that butt.]]
