->''"I'm an intelligent woman. I know the difference between reality and my own dark fantasies. But I thrill at the idea of being taken by a great tentacled beast. My heart races as I imagine my frail and delicate body being controlled, being used by a force too powerful for me to deny. To feel helpless, vulnerable, it scares me yet it excites me. My body aches with desire as I imagine myself being forced to surrender in the most intimate of ways. Can this be so wrong?"''
-->-- '''Kiki''', ''Webcomic/GhastlysGhastlyComic''

Putting the "love" back in "[[Creator/HPLovecraft Lovecraft]]."

This is what happens when you make love (in [[LoveTropes either]] {{se|xTropes}}nse of that phrase) with an EldritchAbomination, or a StarfishAlien doing a passable imitation of one. [[FreudWasRight Tentacles are a frequent feature.]] Can be played for sheer {{Squick}}, horror, {{fanservice}}, [[PlayedForLaughs laughs]] or all of the above at the same time.

Might lead to {{Fetus|Terrible}}[=/=]EnfantTerrible. A common origin for the AntiAntichrist, able to switch sides as a representation of the human side, but just as likely to become a monster.

Subtrope of UnequalPairing and InterspeciesRomance. Compare and contrast DidWeJustHaveTeaWithCthulhu, MarsNeedsWomen, BoldlyComing, and DivineDate.



[[folder:Anime & Manga]]
* The {{O|riginalVideoAnimation}}VA of ''Anime/ElHazardTheMagnificentWorld''. The Demon God destroyed the {{Precursors}}, brought ruin upon the land, and threatened to do the same to present-day El Hazard. Then she and the hero fell in love...
* In ''LightNovel/HaiyoreNyarkoSan'', the protagonist Mahiro did this by accident, having a certain ''je ne sais quoi'' that made Nyarlathotep the Crawling Chaos fall in LoveBeforeFirstSight with him. Most guys would kill to have a beautiful {{Otaku}} girlfriend who [[LovableSexManiac wants to have sex at every opportunity]][[note]] Something Nyarko [[LampshadeHanging lampshades]] whenever he rejects her advances[[/note]], but as a [[AscendedFanboy fan]] of the CthulhuMythos, Mahiro is horrified because he's well aware that Nyarlathotep has 999 other forms, most of which could destroy his sanity if he so much as caught a glimpse of them. (And also just plain finds her [[ManicPixieDreamGirl personality]] annoying.) Later novels show that Mahiro's warming to the idea, with outright confirmation by a third party that he ''is'' in love with Nyarko, even if [[CanNotSpitItOut he's not willing to admit it yet]].
* ''Anime/PonyoOnTheCliffByTheSea'' has Ponyo's human father and sea goddess mother. Granmammare is the personification of the sea and all life therein. Even though she can take the form of a somewhat normal sized human, it's still quite a lop-sided match.
* Chiho Sasaki from ''LightNovel/TheDevilIsAPartTimer'' has this as her ultimate goal, although it's currently one-sided (Maou likes her as a friend and subordinate, but he isn't interested in a relationship). Maou might not be the actual Satan, but he's still the king of demons and capable of attacks so powerful that the aftereffects are visible from orbit. The funny part is that being let in on the {{Masquerade}} was a relief to her since it meant that Emi wasn't his jealous ex-girlfriend.

[[folder:Comic Books]]
* In the ''Series/BuffyTheVampireSlayer'' comics, Dawn infamously does just this in cover art.
* Averted in ''Comicbook/TeenTitans'', where the [[GodOfEvil Demon lord]] [[{{Satan}} Trigon]] mated with human female Arella Roth. He raped her, mating only so she could give him a child that would serve as his portal to the real world, and she almost committed suicide after the act. The child grew up to become the [[DarkIsNotEvil superheroine]] [[DarkMagicalGirl Raven]], who then [[AntiAntiChrist focused on preventing her father from succeeding]]. Trigon himself is the offspring of TheDevil and a human woman (in AnotherDimension).
* Any of Dream's various romances in ''ComicBook/TheSandman'' could be construed as this; Dream's AppearanceIsInTheEyeOfTheBeholder, and since all of his seen relationships have been with human-looking women, they presumably see him (and, one assumes, ''feel'' him) as the pale, thin man the reader sees. However, given his age, power and nature as an AnthropomorphicPersonification this trope is applicable even with the goddess Calliope simply because his power is so far beyond hers, let alone the purely human Nada.
* ''Comicbook/HellBoy'' is the son of a human witch/nun and a demon Prince of Sheol. After he had been conceived, Hellboy did not exist in the real world but was considered to be "a power waiting to be born." Some 300 years later he was summoned to earth as an infant and grew up to be the AntiAntiChrist. His parents really seemed to like each other even though his mother did not want to be the demon's bride at first.
* The ComicBook/IncredibleHulk and [[EldritchAbomination Umar]] once had a fling, [[BlackComedyRape if you can call it that]]. And then [[http://www.comicbookresources.com/prev_img.php?pid=9307&pg=3 she came back for seconds.]]
* Duncan's mom in ''ComicBook/{{Firebreather}}''. The first thing most people think when they show Duncan's [[HotSkittyOnWailordAction monstrous, 100 story tall father]] is "How did that ''work''?" Duncan, however, [[TooMuchInformation does]] ''[[TooMuchInformation not]]'' [[TooMuchInformation want to know]].
* Nova, a former Herald of Comicbook/{{Galactus}} ([[NamesTheSame not to be confused with]] [[Comicbook/{{Nova}} Richard Rider or Sam Alexander]]) had a crush on the PlanetEater. Unsurprisingly, it went nowhere.

[[folder:Fan Works]]
* ''Franchise/TheLegendOfZelda'' fanfiction ''[[http://www.fanfiction.net/s/4061688/7/Feel_Good_Hit_of_the_Summer Feel Good Hit of the Summer]]'' had a character forced to do this to Ganondorf.
* In ''[[FanFic/TheLifeIsAGameMultiverse Naruto: life is a Game]]'' when Naruto faces the Shinigami, he uses his dōjutsu to [[spoiler: suggest that ''she'' become female and join his harem.]]
* ''[[http://www.fimfiction.net/story/9672/near-death-experience Near Death Experience]]'' is all about the protagonist having... well, [[ExactlyWhatItSaysOnTheTin a near death experience]] before falling in love with the GrimReaper.
* ''VideoGame/{{Touhou}}'' fics:
** ''FanFic/MaidensIllusionaryFuneral'' depicts Yukari as a nightmarish void of darkness and eyes that is simply [[AFormYouAreComfortableWith masquerading in a human shape]], and has her develop a tragic, doomed romance with Yuyuko, who is (mostly) human at the time.
** Played for horror in ''FanFic/ImperfectMetamorphosis'' with [[HumanoidAbomination Yuuka]]'s [[DepravedBisexual "affections"]] towards Team 9 and several other characters.
* In the ''Franchise/MassEffect'' fanfic ''[[CrucibleMassEffect Crucible]]'', there were two couple that thanks to the non-mortal partner, also turn into two cases of EternalLove. The first happened in the ancient time, a turian named Makern married Herz who is a living incarnation of the star Trebia (yes, that star of the Trebia system). They had 4 sons who created the four big clans of the North (one of which is the Vakarian).
** Later, it's revealed that there was a human woman who married Sam [[spoiler: Shepard]], who actually was Death that was temporary sealed into a human form by Herz. They had only one child, [[spoiler: Jane]] before Sam died and returned to his true form but he later came back to take his wife's soul with him.
* Any [[{{Imageboards}} greentext]] written by a "[[PeripheryDemographic Brogre]]" will inevitably feature an eldritch version of Franchise/{{Shrek}} who, upon being summoned by children's prayers, shows up to gruesomely kill nonbelievers. These stories also always feature "shrexual" encounters between Shrek and his faithful underage worshipers. [[SchmuckBait If you're]] ''[[SchmuckBait really]]'' [[SchmuckBait curious]], you can read some [[http://knowyourmeme.com/memes/shrek-is-love-shrek-is-life here]], but be warned: these greentexts are ''definitely'' NotSafeForWork ([[{{Gorn}} and]] [[TorturePorn probably]] [[CruelAndUnusualDeath not]] [[{{Squick}} safe]] [[FanDisservice for]] [[BlackComedyRape sanity]] [[BrainBleach either]]).
-->[[MemeticMutation Shrek is love, Shrek is life]]

* In ''Film/{{Dagon}}'', the protagonist has dreams about swimming undersea with a beautiful mermaid. Later, he actually meets her, but resists her attempt at seduction [[spoiler:when he finds out that she has tentacles instead of legs.]] Later on, she turns out [[spoiler:to be his sister, and also his destined bride.]] While featuring a village full of otherworldly interbreeding, this one gets super-bonus-points for being based on [[Literature/TheShadowOverInnsmouth a Lovecraft story.]]
* In ''Film/PiratesOfTheCaribbean'' Davy Jones fell in love with Calypso, the AnthropomorphicPersonification of the sea. He hates and loves her due to her fickle nature, which led him to cut out his own heart to escape the conflicting emotions. Sao Feng aspired to this trope, having fallen in love with the sea and thus Calypso.

* Franchise/CthulhuMythos:
** "Literature/TheDunwichHorror". [[http://en.wikipedia.org/wiki/Yog-Sothoth Yog-Sothoth]] has sex with a human woman and produces the offspring who will be known as Wilbur Whateley. And it's hinted that her elderly father was acting as the, er, ''vessel'' for Yog at the time.
** Michael Shea's "Fat Face" involves a woman who becomes interested in a rather large, but kindly man. [[spoiler:It's not a man, and it doesn't end well.]]
** Played with Ramsey Campbell's "The Faces At Pine Dunes". The protagonist and his girlfriend investigate his parents' strange behavior. [[spoiler: His father is a Human[=/=]EldritchAbomination hybrid, and so is the protagonist.]]
* "The Dunwich Horror" was inspired by Arthur Machen's ''Literature/TheGreatGodPan'', which also features sex (or ''some'' kind of mating) between a human woman and an EldritchAbomination. The resulting daughter is an eerily beautiful HumanoidAbomination whose unspeakable acts (strongly implied to be sexual in nature) lead to madness and suicide.
* Done as part of a DealWithTheDevil in ''Literature/TheDresdenFiles'' [[spoiler:when Harry takes up the mantle of the Winter Knight. Harry states that it wasn't sex, no matter what it looked like. You can't have sex with a hurricane, or make love to a storm.]]
* In the ''Franchise/ConanTheBarbarian'' story ''The Scarlet Citadel'', it is mentioned that the evil sorcerer Tsotha-Lanti is the offspring of a dancing girl from Shadizar who slept too close to some haunted ruins and awoke in the grasp of a black demon. And from that unholy union Tsotha-Lanti was born.
* Literature/TheBible has the {{Nephilim}}, which are the product of [[HalfHumanHybrid angels falling for and lusting after human women.]] Seems like standard InterspeciesRomance, until you read the Book of Ezekiel and realize [[EldritchAbomination angels are far from "pretty boys with wings"]] (although they likely took human form during their affairs with mortal women).
* ''Franchise/{{Star Wars|ExpandedUniverse}}: Literature/FateOfTheJedi'': Luke has an ''encounter'' with [[SealedEvilInACan Abeloth]]. [[spoiler:She ''impersonates each of his previous girlfriends'' and then [[{{Yandere}} sets out to kill the ones that are still alive]]]]. Loving a Skywalker can be so complicated.
* Appears in several works by Creator/NeilGaiman:
** In ''Literature/AmericanGods'' Shadow, the main character, catches the smitten eye of the Egyptian Cat Goddess, Bastet. It doesn't amount to much more than a one night stand and some minor flirting though. [[spoiler:The implications of the trope are minimized when you learn that Shadow is in fact Baldr.]]
** "Literature/AStudyInEmerald" has Queen Victoria (reimagined as an EldritchAbomination) and her human "consort" Prince Albert. Also Prince Franz Drago of Bohemia (another EldritchAbomination) is said to have frequented brothels, and he ends up dying after [[spoiler:Sherlock Holmes lures him to his death with the offer of a virgin kidnapped from a convent.]]
** In "How to Talk to Girls at Parties" the narrator ends up at the wrong party with his friend, flirts with girls who turn out to be {{Anthropomorphic Personification}}s of planets, and is almost consumed by hearing a song from one of them. His friend tries to make out with a ''sun'' and inadvertently pisses her off, and the narrator never hears from him again.
** In ''Literature/TheOceanAtTheEndOfTheLane'' an EldritchAbomination disguised as a human woman seduces and makes love with [[spoiler: the narrator's father]].
* ''Literature/{{Awoken}}'', a work that revels in [[ExaggeratedTrope exaggerating]] the tropes found in ''Literature/{{Twilight}}''-like teen ParanormalRomance, has its ordinary female protagonist fall in love with ''Cthulhu''. A Cthulhu who can take on the form of a gorgeous teenage boy, but still an amoral and murderous Cthulhu.

[[folder:Live-Action TV]]
* In ''Series/{{Smallville}}'', only [[WeirdnessMagnet Chloe Sullivan]] could get involved with [[spoiler:''Doomsday''.]]
* Creator/{{Elvira|MistressOfTheDark}} denies that she worships the Devil, but admits that she [[DivineDate dated him once.]]
* While the TARDIS from ''Series/DoctorWho'' is not eldritch in a negative or scary sense, she is undoubtedly one of the most powerful and bizarre entities on the show. She's a pandimensional GeniusLoci in the form of a blue police box with an infinite PocketDimension on the inside, and she exists simultaneously at every point in time and space. And in [[{{Recap/DoctorWhoS32E4TheDoctorsWife}} "The Doctor's Wife"]] (written by Creator/NeilGaiman--see the Literature section above), when she briefly possesses a woman's body and comes face-to-face with the Doctor... epic flirting ensues, with the heavy implication that the Doctor wasn't aware they've always been in a relationship. It doesn't go any further than flirting, though. (And at another point in the episode, the TARDIS flirts with [[UnfazedEveryman Rory]].)
-->'''The Doctor:''' Do you have a name?\\
'''Human TARDIS:''' Seven hundred years and finally he asks.\\
'''The Doctor:''' What do I call you?\\
'''Human TARDIS:''' What do you call me? Sexy.\\
'''The Doctor:''' Only when we're alone.\\
'''Human TARDIS:''' We ''are'' alone.\\
'''The Doctor:''' Oh. Come on then, Sexy.
* In ''Series/{{Angel}}'' season 5, ''something'' develops between [[TookALevelInBadass Wesley]] and [[HumanoidAbomination Illyria]], mostly because she reminds him of Fred, and much angst ensues when she impersonates her. It isn't clear until the series finale that [[spoiler:Illyria returned his affections, as evidenced by her compassion and grief at Wesley's death]].

* The song "Width of a Circle" by Creator/DavidBowie describes a consensual encounter with some sort of EldritchAbomination. Remember, kids, DrugsAreBad!
* Norm Sherman's "Heartache Over Innsmouth", which is just what it sounds like.
* The music video for "Peacebone" by the experimental rock group Music/AnimalCollective shows a blossoming romance between a human woman and... something else.

[[folder:Tabletop Games]]
* ''TabletopGame/CallOfCthulhu'':
** Yog-Sothoth can mate with human females, creating the Spawn of Yog-Sothoth.
** ''Masks of Nyarlathotep'' campaign. A woman named Hypatia Masters apparently mated with a Great Old One (she became pregnant and had its child).
** Supplement ''The Fungi from Yuggoth'', adventure "The Thing in the Well". After donning a pair of magical glasses a woman is raped by an other-dimensional monster and becomes pregnant with its child.
** The ''Cthulhu Now'' adventure "Love's Lonely Children" adventure features a couple who are Y'Golonac cultists. Y'Golonac is the Mythos entity of {{Squick}} incarnate. The husband is possessed and bodily transforms into Y'Golonac, while his wife... worships. [[TheAristocrats And they got their daughter involved in it, too...]]
* ''TabletopGame/{{Exalted}}'':
** In one of the [[FanonDiscontinuity more contested]] passages in the guide for Infernals, it's suggested that new Infernals are passed around the Yozis for... "initiation." The Yozis are crippled godlike entities that take forms such as a city of brass and basalt, a hundred thousand crystalline spheres of fire, and an ever-twisting river. The sheer physics alone... But, for good or ill, the actual process would be a bit less mind-hurting, as the Yozis can create humaniform avatars called jouten. This is not necessarily an improvement.
*** The Ebon Dragon is stated to only have one Jouten [[GenreSavvy because]] he would [[ChronicBackstabbingDisorder betray himself]]. The form he uses: [[AttackOfThe50FootWhatever A several miles long oriental dragon made of darkness]]
** The Yozi Adorjan (who mostly appears in the form of an extremely violent wind) also mated with a Solar Exalt (through a dream...) and conceived daughters by him (three were normal human children, while the other four shed their mortal bodies when they reached maturity and became living winds like their mother).
** The god[[GenderBender (dess)]] Luna was created (partially) for the purpose of seducing the Primordial Gaia (and fell in love with her instead). Gaia's most commonly seen form is her humanoid jouten, but mentions are made of her other, greater forms, that are vast, primal and slightly terrifying to the gods (although Luna, while typically humanoid, [[VoluntaryShapeshifting can take some pretty eldritch forms herself]], so the line between regular romance and romancing Cthulhu is a bit blurred).
** TheFairFolk are vortices of chaotic energy pretending to be people, and half-fae are a well-established bit of setting lore.
* ''TabletopGame/{{Pathfinder}}'':
** The "[[EldritchAbomination aberrant]]" [[InTheBlood bloodline]]—-which eventually turns your character into a HumanoidAbomination-—implies something like this in a [[WitchSpecies sorcerer's]] ancestry.
** The 4th bestiary includes the Spawn of Yog-Sothoth mentioned above as a monster-type, and notes that some of Yog-Sothoth's half-mortal children take more after their humanoid parents, becoming aberrant bloodline sorcerers instead.
* This is practically the point of ''TabletopGame/{{FATAL}}'', which has many mechanics for humans mating with demons, abominations, and the like. ''FATAL'' being, well, ''FATAL'', most of these matings are non-consensual.
* In ''TabletopGame/DungeonsAndDragons'' this is inevitably the backstory of half-dragons, half-demons, half-celestials, planetouched and the like.

[[folder:Video Games]]
* ''VideoGame/CthulhuSavesTheWorld''. Umi falls in love with Cthulhu at first sight, but he considers them "strictly in a rock star-groupie relationship." [[spoiler: By the end though, he comes to return her feelings.]]
* In ''VideoGame/{{Disgaea 2|Cursed Memories}}'' Adell delivers a [[CooldownHug Cooldown Kiss]] to [[spoiler:Zenon, God of all Overlords.]]
* ''VideoGame/{{Persona 3}}'':
** In ''Portable'', on the Female Main Character's route, you're given the chance to initiate a romantic S.Link with [[spoiler:Ryoji Mochizuki, the human form of Nyx Avatar]]. That is, you can make [[spoiler:the personification of Death itself]] fall in love with you.
** While it's not an official social link, a male main character is asked to show Elizabeth what sex is like during their last outing. The female main character can similarly win the affection of, and have an OptionalSexualEncounter with, Elizabeth's younger brother Theodore. It's not clear exactly what Elizabeth and Theodore ''are,'' but whatever they are, it's not human, and as the game's {{Bonus Boss}}es they are just as if not more powerful than the above mentioned character.
* ''VideoGame/{{Persona 4}}'':
** You can fulfill the requests of the big sister of the aforementioned Elizabeth and Theodore, Margaret. If you do, her comments toward you become more and more flirty and, if you finished them all, she will steal a kiss towards the end of the game and tease you about meeting again in the future.
** [[spoiler:Marie]] in ''[[UpdatedRerelease Persona 4 Golden]]'' on the PS Vita is a bona fide romantic social link and [[spoiler:an alter ego of Izanami, the former mate of Izanagi (who, incidentally, is ''your'' alter ego)]].
* In ''VideoGame/TheBardsTale'', you're unknowingly [[spoiler:setting free (or not) a Demon Queen. You guessed it, Caleigh]]. Though she does keep her promise to you.
* ''Franchise/DragonAge'':
** One of the [[RomanceSidequest potential love interests]] in ''VideoGame/DragonAgeII'' is an Abomination, a human who has been possessed by spirits/demons. Several characters discuss and lampshade the squickier aspects of the relationship. (This means that every intimate encounter Hawke shares with his/her Abomination LoveInterest is technically a threesome.)
** Played For Laughs in ''VideoGame/DragonAgeInquisition'' when Blackwall asks local Fade expert [[HermitGuru Solas]] if he's ever been intimate with a [[OtherworldlyAndSexuallyAmbiguous Fade spirit]]. Solas grows flustered, and insists that [[SuspiciouslySpecificDenial nothing in the Fade is ever simple]], but seeing as he never actually ''denies'' the accusation...
*** A female elven Inquisitor romancing [[spoiler:Solas]] is unwittingly engaging in this, as [[spoiler:he is really Fen'Harel, who can be compared to Loki in his role in elven mythology]].
* In ''VideoGame/DiabloIII'', Adria [[spoiler:conceived Leah with Aidan while he was possessed by Diablo]]. And she knew it. ''Adria had consensual sex with [[spoiler:the Lord of Terror''.]]
* In ''[[VideoGame/NeverwinterNights2 Mask of the Betrayer]]'', you play as a soul-eating abomination whose mere existence poses a threat to those around you. This does not stop you from getting a RomanceSidequest.
* In ''VideoGame/FireEmblemAwakening'', a Male Avatar can marry [[PersonOfMassDestruction Tiki]], who was put to sleep by Naga to keep her from degenerating into madness, which would destroy the world. Furthermore, all of [[spoiler:the Avatar's romance options boil down to "Did You Just Romance The Avatar of Grima?"]].
* Justified in the "good" ending of ''VideoGame/{{Eversion}}'': [[spoiler:Princess Nehema is revealed as an EldritchAbomination in the bad ending, but in the good ending Zee Tee is one too.]]
* You can cause this in ''[[VideoGame/{{Scribblenauts}} Super Scribblenauts]]'' by summoning Romantic Cthulhu and Romantic [Anything Else].
* In the backstory of ''Videogame/BrutalLegend'', the hero Riggnarok and the Demon Emperor Succoria traveled to the future (Eddie's time). Succoria had a VillainousBSOD when she saw that humanity was the dominant species and the Tainted Coil was extinct, meaning her people were destined to lose. Riggnarok pitied her and decided to care for her instead of slaying her. Eventually, they fell in love. Sadly, Succoria died in childbirth, and Riggnarok raised their son [[spoiler:Eddie Riggs]] by himself. Assuming [[spoiler:Eddie's demonic form]] takes after his mother, Succoria looked every bit as monstrous as the rest of the Tainted Coil when she and Riggnarok kindled a romance.
* In ''Video/{{Bloodborne}}'', [[spoiler: '''You''', the [[PlayerCharacter Hunter]], as an EldritchAbomination, falls in love with a [[AnimateInanimateObject doll]], should you consumed all three Umbilical Cords and drove away both [[DirtyOldMan Gehrman]] and the [[GreenEyedMonster Moon Presence]], you two will be HappilyMarried.]]

[[folder:Visual Novels]]
* ''VisualNovel/SayaNoUta'' is about the main character (unknowingly) romancing one of these. He suffers from a condition which caused him to view everything as {{Eldritch Location}}s and everyone as {{Eldritch Abomination}}s, which is why Saya, who herself is an actual EldritchAbomination, was the only one to look normal in his eyes. It's also an extremely dark example, as his use of Saya as a LivingEmotionalCrutch can eventually cause him to cast aside his humanity and cross the MoralEventHorizon to perform such acts as [[spoiler:murder, rape and cannibalism]]. Saya, with a [[BlueAndOrangeMorality flimsy grasp on human morality]] and herself possibly suffering from SanitySlippage, makes exactly one attempt to stop his downward spiral by offering him the chance to return to the normal world by curing his condition. If he refuses and vows to stay with her no matter what, she happily helps him along down the slippery slope until he too begins sharing her BlueAndOrangeMorality.
* In ''VisualNovel/DraKoi'' the protagonist starts a relationship with a dragon that is along the lines of an eldritch abomination: It casually breaks the laws of physics and is hinted to spread madness.
* ''VisualNovel/{{Demonbane}}'' has quite a lot of this going around. First, Al Azif, aka the ''Necronomicon'', is romanceable. [[spoiler:The sequel reveals that, in at least one universe, the protagonist and she had children... don't ask how that works.]] One of the main antagonists, Master Therion, is the result of another: [[spoiler:he's the offspring of one of the most powerful sorceresses to ever live... and Yog-Sothoth]]. It is also possible to trigger sex scenes with such beings as Atlach-Nacha, Cthugha, Ithaqua, and [[spoiler:Nyarlathotep]].

[[folder:Web Comics]]
* ''Webcomic/OwMySanity'' combines this with UnwantedHarem.
* ''Webcomic/SluggyFreelance'' has a hint of this in a TV show actually called [[http://www.sluggy.com/comics/archives/daily/021110 "Unholy Concubine Connection"]]. (Before that comic, the show showed someone "merely" involved with {{Satan}}.)
* In ''FanFic/GrimTalesFromDownBelow'', it turns out that years after ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', [[TheGrimReaper Grim]] and [[EnfantTerrible Mandy]] [[UnholyMatrimony married]] and had two kids. [[spoiler:Though actually the boy is an abortion from an unknown father, and the girl's father is [[HumanoidAbomination Nergal Junior]], as Grim can't actually father new life, because he's ''Death''.]]
* ''Webcomic/DrowTales'':
** Any drow who has a relationship with a Vel'akar, or a sentient demon from "beyond the veil". Snadhya'rune is heavily implied to have had a sexual relationship with her protector twin Khaless[[note]]who was not actually related to her, meaning it wasn't ''technically'' incest[[/note]] before the latter got possessed by one, but it's not certain if their relationship continued after it happened.
** Chapter 46 [[http://www.drowtales.com/mainarchive.php?sid=10004 gives us the rare sight]] of one Cthulhu ([[spoiler:the aforementioned Khaless]]) romancing another Cthulhu ([[spoiler:Kharla'ggen]]) and the results are pure FanDisservice.
* The Lord King[[note]]The Erlkönig[[/note]]/Widow Norrington[[note]]Fully human[[/note]] pairing in ''Webcomic/{{Roommates}}'' is either this trope or DivineDate depending on what you think about TheFairFolk. The guy also refuses to be categorized by hunting with [[Myth/NorseMythology Odin]] but playing poker with {{Franchise/The Slender Man|Mythos}}.

[[folder:Web Original]]
* ''{{Website/Cracked}}'' uses this as one of the potential next Twilight-style monster/teenager romance trends [[http://www.cracked.com/blog/the-vampire-formula-what-women-see-in-them/ here]].
* [[http://suptg.thisisnotatrueending.com/archive/16727562/ /tg/]] likes [[http://suptg.thisisnotatrueending.com/archive/16309898/images/1316145554772.jpg these]].
* The twist of [[http://www.youtube.com/watch?v=UcwswB7Rbbs "Wilhelm Park"]] by redminus.
* WebVideo/TheNostalgiaChick and her sidekicks Nella and Elisa plus a few ghostwriters (under the {{Portmanteau}} pen name JustForFun/SerraElinsen) released a "crowd-sourced" ParanormalRomance novel that they originally described as "''{{Literature/Twilight}}'' with aliens." By incorporating the suggestions of their fans, they eventually make the story about an ordinary teenage girl and a Lovecraftian EldritchAbomination who fall in love. [[http://www.amazon.com/Awoken-Serra-Elinsen/dp/1491268727/r The book is out]] under the name ''[[Literature/ViridianSaga Awoken]]'', and given it goes right with Lovecraftian names such as Cthulhu and Azatoth is apparent that they're going all the way.
* In the ''Literature/WhateleyUniverse'', Sara Waite is a HumanoidAbomination, so anyone she has sex with counts. For that matter, her father Gothmog is by all accounts ''still'' quite popular with the ladies.

[[folder:Western Animation]]
* On ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'', Billy's aunt marries Nergal, a tentacle demon from the center of the earth who apparently aimed for [[AFormYouAreComfortableWith a form humans are comfortable with]] and missed.
* In ''WesternAnimation/RickAndMorty'', Rick has a romance with Unity, an extraterrestrial hivemind.
