->''"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. See also EvilIsSexy, a related but dissimilar and partial SuperTrope.

Compare and contrast DidWeJustHaveTeaWithCthulhu, MarsNeedsWomen, BoldlyComing, and DivineDate.



[[folder:Anime & Manga]]
%% Many of the anime given were not a examples of this trope. These were examples of either HumanoidAbomination, PhysicalGod, or InterspeciesRomance. "Did You Just Romance Cthulhu?" requires one of the parties to be non-humanoid. Their level of personal power is irrelevant.
* 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/NyarkoSan Haiyore! Nyako-san]]'', the protagonist Mahiro did this on 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]]A fact which 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. 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.

[[folder:Comic Books]]
* In the ''Series/BuffyTheVampireSlayer'' comics, Dawn infamously does just this in cover art ([[NotSafeForWork not safe for humanity]]).
* 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.]]
* 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.

* Any [[Podcast/WelcomeToNightVale Cecil/Carlos]] fic that goes for the Fanon idea "Cecil is a [[HumanoidAbomination Humanoid]] / [[EldritchAbomination Eldritch Abomination]]" fit into this trope.
* ''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.
* As far as the ''VideoGame/{{Touhou}}'' fandom goes in {{Shipping}}, anytime a human, or even a low-level {{youkai}}, is paired with one of the more [[SuperpowerLottery stupendously powerful]] residents of Gensoukyou it is almost always this trope. Probably the most prevalent is the Reimu/Yukari pairing, the former a (relatively) normal human and the latter a RealityWarper and borderline HumanoidAbomination.
** Played for horror in ''FanFic/ImperfectMetamorphosis'' with Yuuka's "affections" towards Team 9.
* In ''Manga/{{Naruto}}'' fanfiction, the title character is often paired with Kyuubi.
** ...Though, many people can't [[AmbiguousGender figure out its gender]]
** 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.]]
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' Discord is a full-blown [[RealityWarper reality-shattering]] MadGod, but fans regularly create {{Crack Pairing}}s with him and the more normal characters. The most popular are with Pinkie Pie (both chaos-causing {{Cloudcuckoolander}}s, albeit Pinkie on a ''much'' smaller scale), [[AngelDevilShipping with Celestia]], and [[UnholyMatrimony with Queen Chrysalis]].
* ''FanFic/{{Greenfire}}'': ([[AlternateUniverse Spike]]) is rather low on the scale of cosmic horrors, being only a young, intimidating dragon, but society at large considers his relationship with [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rarity]] as this.
* ''[[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.

* 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.]][[note]]While featuring a village full of otherworldly interbreeding, this one gets super-bonus-points for [[Literature/TheShadowOverInnsmouth actually being based on a Lovecraft story.]][[/note]]
* 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.]]
* ''[[Franchise/StarWarsExpandedUniverse Star Wars]]: 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.
* The entire point of ''LightNovel/HaiyoreNyarkoSan'', except that it's the Cthulhu-side person herself who initiates the relationship to the human protagonist (to varying degree of success). And no, it's not nasty... most of the time.
* Appears in several works by Creator/NeilGaiman. (Also appears in one of the ''Series/DoctorWho'' episodes he wrote; see the "Live-Action TV" section below.)
** In ''Literature/AmericanGods,'' a man sleeps with a prostitute who turns out to be a succubus-like monster. The prostitute ends up swallowing the unlucky man through her vagina. In less of a nightmare-inducing example, 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.]]
** In "AStudyInEmerald" we have Queen Victoria (reimagined as an EldritchAbomination) and her human "consort" Prince Albert. Also in this story, 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]].
* In the Literature/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.
* The premise of the ''Literature/ViridianSaga'' (with Cthulhu himself to boot!)
* A recurring theme in Paul Magrs' ''Brenda and Effie'' novels, especially in Never The Bride, which includes a story about the grandchildren of one of the aliens from ''War Of The Worlds''.
* 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".]] It's implied that during their relationships with humans, that they took on a human form. [[BlueAndOrangeMorality Then again, they might have]] [[DoubleStandardRapeDivineOnMortal just done as they pleased]] [[ValuesDissonance without bothering]] [[FridgeHorror to change how they looked.]]

[[folder:Live-Action TV]]
* In ''Series/{{Smallville}}'', only [[WeirdnessMagnet Chloe Sullivan]] could get involved with [[spoiler:''Doomsday''. Although he is in human form most of the time. Not explicitly stated, but in ''Eternal'' she locks Davis and herself alone in the basement.]]
* 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]].
* 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.
-->'''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.
** At another point in the episode, the TARDIS (still in the body of a woman) flirts with [[UnfazedEveryman Rory]]:
-->'''The Doctor:''' Can you get a message to Amy? The telepathic circuits are online.\\
'''Human TARDIS:''' Which one's Amy? The pretty one?\\
'''Rory:''' Argh. \\
'''Amy:''' Rory, what's wrong? \\
'''Rory:''' It's like I'm getting a [telepathic] message. \\
'''Human TARDIS:''' Hello, Pretty.

* The song "Width of a Circle" by Creator/DavidBowie describes a consensual encounter with some sort of EldritchAbomination. Remember, kids, DrugsAreBad!
* Also Norm Sherman's "Heartache Over Innsmouth", which is just what it sounds like.

[[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.
* The "[[EldritchAbomination aberrant]]" [[InTheBlood bloodline]] in ''TabletopGame/{{Pathfinder}}''—-which eventually turns your character into a HumanoidAbomination-—implies something like this in a [[WitchSpecies sorcerer's]] ancestry.
** The 4th bestiary also 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 part of the ''graduation ceremony'' for the Drow priestesses of Lolth in ''TabletopGame/ForgottenRealms''. The joint graduation ceremony between female priestesses and male warriors consists of the two groups engaging in a drug-fueled orgy. The top priestess in her class mates with a glabrezu--a twenty-foot-tall four-armed dog-faced demon (and two of its arms end in gigantic pincers)--instead of another Drow. It bears mentioning that glabrezu can't shapeshift. This is considered an honor, and the resulting hybrid children (called draegloths) have a special place in Drow society.
* 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.

[[folder:Video Games]]
* ''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.]]
* ''VideoGame/{{Disgaea 2|Cursed Memories}}'': Adell has delivered a [[CooldownHug Cooldown Kiss]] to [[spoiler: Zenon, God of all Overlords.]]
* It's not entirely certain ''what'' the girl in ''Where We Remain'' is, but we know that she's spent a very long time [[SealedGoodInACan magically bound in a cave]], that she didn't have a name before the hero [[HelloInsertNameHere gave her one]], and that she has some [[RealityWarper rather nifty]] ([[GodsHandsAreTied if limited]]) abilities. Given that [[spoiler:the wind spirits on the island are described as her "brothers,"]] it would seem that she's nonhuman rather than just some sort of spellcaster.
* ''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]], [[spoiler: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 [[spoiler:Ryoji]].
* ''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, who is a bona fide romantic social link and [[spoiler:an alter ego of the BiggerBad, 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.
* One of the [[RomanceSidequest potential love interests]] in ''VideoGame/DragonAgeII'' is a HumanoidAbomination. Several characters discuss and lampshade the squickier aspects of the relationship. For those unfamiliar with the setting, Abominations are humans who have been possessed by spirits/demons. This means that every intimate encounter Hawke shares with his/her Abomination LoveInterest is technically a threesome.
* 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.
* 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...
** Not to mention [[spoiler:a female elven Inquisitor romancing Solas is also unwittingly engaging in this, as Solas is really Fen'Harel, who can be compared to Loki in his role in elven mythology]].

[[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 eventually causes 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 no attempt to stop his downward spiral and even helps him along.
* 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''.]]
* In ''Webcomic/DrowTales'', this could apply to 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. Looks mostly human but isn't, also [[ArsonMurderAndJaywalking steals children, hunts people and trolls the cast]][[/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 [[NorseMythology Odin]] but playing poker with {{Franchise/The Slender Man|Mythos}}.

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.
