->''"As regards sexual intercourse with older or younger copies of yourself, it's incest in branching or changeable timelines, and masturbation in inevitable timelines. In either case, yes, it is gay."''
-->-- '''Creator/{{Tailsteak}}''', [[http://tailsteak.com/archive.php?num=491 "Basic Time Travel Etiquette"]]

It's a simple tale: Person photocopies self, or travels to an AlternateUniverse, or [[TimeTravel another time]]. Person meets self. Both selves [[UnusualEuphemism "make beautiful music"]] together. After all, what better person to be most intimate with?

Probably more prevalent in {{fanfic}}tion than in original works, but it's out there. Technically, any [[FoeYay intimacy]] between a character and their EnemyWithout will be this. Expect much argument amongst the characters, fans, and oftentimes even both as to whether this qualifies as actual sex, incest (it could be considered super-incest, since there's no closer relative possible than ''yourself'', as even an [[{{Twincest}} identical twin]] will have some minute, statistically negligible genetic differences), or masturbation.

In erotica, this is often considered more acceptable than most other types of fetishes (like say, incest), seeing as it's, well, ''impossible'' in reality.[[note]]For now, anyway. Cloning's coming along pretty nicely.[[/note]]

Also known as selfcest, autoincest, clonecest, incesturbation, or [[JustForPun doppelbanger]].

Compare and contrast OppositeSexClone, {{Twincest}}, MyOwnGrampa.

Note that [[JustForFun/IThoughtItMeant this is not the same]] as ADateWithRosiePalms.

[[JustForFun/IReadThatAs Nor is it the same as]] ScrewYouElves.

Often is an invoked case of ItsOkayIfItsYou. If the character otherwise generally considers themself asexual, might very well be a case of SingleTargetSexuality.



[[folder:Anime & Manga]]
* ''Manga/RanmaOneHalf'': Both the manga and anime explored this, though in different manners:
** The anime {{filler}} story, which came first, created a female-only (and ''demonic'') copy of Ranma that tried to seduce him to steal his life force, causing him to stumble around zombie-like during the day.
** The manga version centered on a haunted mirror, which created identical copies of whoever looked into it. Since the mirror had [[SoulJar trapped the spirit of a girl who had longed to have a boyfriend]], any resulting copies would then chase anyone of the opposite sex, and try to date them. When a mirror-copy of girl-Ranma was made, she was immediately smitten with boy-Ranma, and she tried to bed him on her very first night of existence. At the end of the story, a male clone was created accidentally, and both copies happily hooked up (since it would take another week for the seal on the mirror to be fixed, whatever they did afterwards belongs [[PowerPerversionPotential in the realm of imagination]] (and {{Doujinshi}}).
* Susumu and Nanako from ''Manga/{{Homunculus}}'', who have sex with each other after Nanako's trepanation. They each hallucinate their partner as themselves, just with the body of the other gender (but the heads stay the same). This trope is then exploited for creeps over the next few pages in soft-core pornographic detail.
* ''Anime/YesPrettyCure5'':
** When each Pretty Cure besides Dream is forced to face an EnemyWithin while wearing the Mask of Despair. Cure Lemonade faces a creepily affectionate version of her civilian self.
** Also, a sticker set for the second season exists pairing each girl up with her implied or stated love interest: Dream with Coco and Komachi with Nuts, both of which became canon in season one; Karen with Milk, which [[HideYourLesbians can't be outright stated but is pretty darn close]]; Urara and Rin with Syrup, both of which are currently implied (but Urara seems to be winning, despite Toei earlier saying otherwise... Rin has bad luck with boys, doesn't she?), and Kurumi with... Milk again. Herself. Yeah.
* Happens in the second episode of ''Anime/{{Kaiba}}''; the woman who helped the title character sneak onboard a spaceship copies her own memories into his body and the two of them have a little fun together... which is quite disturbing given the series' surreal and childlike artstyle. Then the copy kills the original for fear of being deleted.
* Technically, the implied attraction between ''Anime/{{Madlax}}'' and [[spoiler:[[MindScrew her progenitor/creator/original self]] Margaret]] would be this, seeing how she is her [[spoiler:EnemyWithout of sorts]].
* In {{Hentai}} manga ''Alice in Sexland'', an artisan created a cupboard that can spawn a perfect {{Hermaphrodite}} (and perfectly horny) clone of its female user.
* ''Manga/KatekyoHitmanReborn'':
** The relationship between Mukuro and Chrome tends to feel like this. Their names are actually anagrams of each other (in Japanese "chrome" is pronounced "kuromu") [[note]] even their last names are an anagram: Rokudo and Dokuro[[/note]], and they look incredibly similar (other than the gender difference), coupled with the fact that they ''share a body''...
** Most people think [[http://www.onemanga.com/Katekyo_Hitman_Reborn/237/15/ Tsuna and Kyoko]] are the closest thing to this without really being related.
* Closely related: Jail Scaglietti of ''Anime/MagicalGirlLyricalNanohaStrikers'' impregnated [[spoiler:a perfect clone of himself into]] Uno, who was revealed in the third [[AudioAdaptation Sound Stage]] to be his OppositeSexClone. Of course, he likely did it [[MadScientist in a scientific way]], but the lack of information on how he specifically did it inspired [[RuleThirtyFour some theories that are more base]]. Of course, he did this with all the rest of his cyborg "daughters" too. It's just that Uno is the only one that's an OppositeSexClone.
* Patalliro of ''[[Manga/{{Patalliro}} Boku Patalliro]]!'' has molested and been molested by nearly identical Patalliros of the distant past and future. Presumably they are both ancestors and descendants of the main Patalliro. Let that sink in.
* In ''Beat Angel Escalayer'', Sayuka gets raped by [[spoiler:[=FM77=], who is based off her, though may not actually be a clone. Oddly enough, after a DefeatMeansFriendship, she develops the "cute little sister" personality.]]
* ''Manga/SailorMoon'':
** Okay, it never got to "screwing", but in the manga [[spoiler:Sailor Cosmos kissed Sailor Moon. Sailor Cosmos is ([[ShrugOfGod apparently]]) Sailor Moon from a BadFuture. [[Series/SaturdayNightLive Discuss]].]]
** Neo Queen Serenity was also pretty excited to see her past self...
* In ''Manga/KaguyaHime'', a few characters express interest in the bodies of their clones, but that's (probably) usually because they need their organs. Julian, though, is definitely ''very'' interested in his clone Miller; among other things, he mentions having seen an almost-unnoticeable scar on Miller's body during a sex scene in one of the films Miller played in, and later does something that was either nuzzling his face very tenderly, or kissing him (darn you, DiscretionShot). Not to mention the [[HeroicSacrifice reason he wanted to find Miller in the first place]].
* The last (non-canon) episode of ''LightNovel/{{Kampfer}}'' ends with the gender-swapping protagonist married to him/herself. And he/she/they had a child.
* The {{yuri|Genre}} one-shot, ''Endless Narcissus'', is about a girl who loves herself so much she goes and gets a clone of herself ([[spoiler: Her clone turns out to be just as {{Yandere}} as she is, and [[IfICantHaveYou murders her out of jealousy]], just as she had done to someone else before]]).
* The Inspectors anime of ''VideoGame/SuperRobotWarsOriginalGeneration'' has Alfimi kissing Excellen while her clothes start disintegrating.[[labelnote:SPOILER]]Alfimi is a loli Einst copy of Excellen[[/labelnote]]
* The BaitAndSwitchCredits of ''Anime/PuellaMagiMadokaMagica'' feature a TransformationSequence in which a pair of naked Madokas get extremely cuddly with each other. This might be the only time you'll see a MagicalGirl get dressed via [[Memes/{{Anime}} symmetrical docking]].
%% ''Bondage Fairies'' was cut for violating the content policy. Do not restore the pothole.
* ''Bondage Fairies'': Fairies are apparently so narcissistic, they will do their own reflections... which turns out to be a bad thing, since [[spoiler:they'll often waste away in the process]].
* Invoked in ''Anime/MacrossFrontier [[TheMovie The False Songstress]]'' and ''Wings of Goodbye'' where part of [[IdolSinger Sheryl's]] on stage performances involve her being seduced by herself (or rather a holographic projection of herself, often times in [[AttractiveBentGender male clothing]]).
* The opening of ''Anime/LupinIIITheWomanCalledFujikoMine'' ends with two Fujikos making out.
* In the final volume of ''Manga/DevilmanLady'' [[spoiler: it is revealed that Lucifer reincarnated himself into this world as a sister and brother (who changed his gender to hide himself), then had sex with him/her/themselves, became pregnant, gave birth (within hours of the act), then fused back into one hermaphrodite self--all of this to give birth to a man who was his beloved in previous life... Yup. [[WhatDoYouMeanItWasntMadeOnDrugs It must have been made on drugs]].]]
* In ''LightNovel/HaiyoreNyarkoSan'', protagonists Mahiro and Nyarko undergo a FreakyFridayFlip... which affects Nyarko's attempts to seduce Mahiro not a single iota. She doesn't seem to understand why he gets so freaked out when she barges into the bathroom, giving him an eyeful of his own naked body and suggesting they "get to know each others' bodies".
* The second series of ''Anime/MagicKnightRayearth'' has a dark variation of this, combined with EnemyWithout. Anime-only villainess Nova is [[{{Yandere}} violently obsessed]] [[PsychoLesbian with Hikaru]], often declaring her love for Hikaru and threatening to murder her and anyone she loves in the same breath. One of the openings even had Hikaru kissing a reflection of Nova. Late in the series, [[spoiler: it was revealed that Nova is actually the manifestation of Hikaru's self-hatred and dark feelings after killing Princess Emeraude. The last episode has Hikaru accepting that Nova is a part of herself and returning to her body.]]
* In the last episode of ''Anime/BlackRockShooter'', Strength reveals that the Otherselves fight because they love their human counterparts. She caresses Yuu's face and says she loves her.
* In ''Anime/ShamanicPrincess'', when young Tiara is trying to tame her bond creature-to-be Graham, her latent power manifests as a [[EnemyWithout red-skinned (and naked) version of her powered-up form]] as an adult. It proceeds to grab her and give her a deep kiss.
* In ''Manga/TokyoGhoul'', Kaneki has repeatedly hallucinated conversations with alternate versions of himself that fuel what fans have dubbed "Kanekicest". The first time, his alternate self borrows the form of his former girlfriend, but reminds him that she's actually him. He ends up pinning her to the ground and straddling her suggestively before [[InterplayOfSexAndViolence eating her]] while she praises him. Later encounters with himself involve considerable cuddling, hand-holding, [[HeadButtOfLove Headbutts of Love]], and borderline molestation. Suffice to say, Kaneki needs a hug and the only person to give it to him is himself.
* Heavily implied in the OVA of ''Anime/HyperdimensionNeptuniaTheAnimation'' between Vert and her AlternateSelf.
* In Manga/OtomeNoTeikoku Mahiro and Mahiru are so alike one would be forgiven for thinking them twins, but in reality they are unrelated and they are obsessed with each other.
* In ''Manga/FateKaleidLinerPrismaIllya'', Chloe/Kuro tries to force an intimate relationship with Illya, who she is a copy of, on at least one occasion. They're interrupted before she can get very far.

* In one bit, stand-up comedian Creator/DavidCross jokes about this guy at the gym fantasizing about pulling himself out of the mirror, and the two thems dance to Music/BarbraStreisand music, make out, and then "they fuck each-other on the Flexinator 500!"
* The basic premise of [[http://www.youtube.com/watch?v=MAD7ZJ6UPeg this sketch]] by the ''Series/TheWhitestKidsUKnow''.
* In a broadly similar vein, Creator/WoodyAllen once quipped: "Don't knock masturbation, it's sex with someone I love."
* A common joke: "My own clone! Now neither of us will be virgins!"
* In one of Creator/JimGaffigan's specials, he says couldn't have sex with another man, "unless he looked like me." "Jim-on-Jim" action, indeed.

[[folder:Comic Books]]
* Jamie Madrox (a second-string [[ComicBook/XMen X-affiliated]] character) has the power of self-duplication, which allows him to split into multiple physical copies of himself, sometimes with distinct personalities. Guess what trope comes up in about 90% of Madrox-related {{Fanfic}}. One of Madrox's duplicates brings out the subject when he's sitting bored at a bar. He indicates he'd rather continue to be bored.
* An unusually blatant example, ComicBook/TheSentry and the Void are both alter-egoes of the same man, split into two bodies, who have passionately kissed on at least one occasion. [[spoiler:Void tells Sentry he loves him and then aggressively tongue kisses him. Sentry responds by ''[[HurlItIntoTheSun tossing Void into the Sun!]]'', so he obviously didn't enjoy it.]]
* ComicBook/{{Supergirl}} has an alternate-universe doppelganger named Comicbook/PowerGirl, who is basically her, only ten years older and more aggressively individualistic, with shorter hair and... well, if you've ever heard of the character, [[MostCommonSuperpower you know what else]]. There is a(n un)surprising amount of Supergirl×Power Girl slashfic. In 2013, DC took advantage of this, announcing Supergirl would soon lose her virginity to Power Girl. [[AprilFoolsDay Guess what day they announced it on?]] [[DudeNotFunny The fans were not amused.]]
* ''ComicBook/XXXenophile'' delved into the trope more than once, with an unexplained duplicate in "Self Indulgence", alternate-reality counterparts in "Dopplegangbang", clones in "Family Reunion", and a situation in "Heart of Stone" where a cleric has to turn two of her fellow party members into illusionary duplicates of herself in order to satisfy the conditions of a curse.
* Once he discovers that [[spoiler:the Jaeger-monster]] is [[spoiler:the AnthropomorphicPersonification of his anger]], ''ComicBook/{{Finder}}'''s Magri White declares that he can do as he pleases with him, and proceeds to play tonsil hockey with him.
* [[PlayingWithATrope Played with]] in ''ComicBook/CerebusTheAardvark''. Cerebus learns about halfway through the series that he is a hermaphrodite whose [[ArtisticLicenseBiology genital arrangement could have led to him impregnating himself]] if his uterus had not been permanently damaged when he was a child.
* Comicbook/{{Deadpool}} once went to another dimension where he encountered a female version of himself and they made out. He then declares {{Squick}}.
* In ''Little Ego'' (an erotic parody of ''ComicStrip/LittleNemo''), Ego has a dream where her reflection steps out of the mirror and starts to have sex with her. Then the reflections of both of them step out of the mirror and join them. And then the reflections of all four. And then she wakes up.
* In ''ComicBook/GreenLantern'' comics, the title character's girlfriend, Carol Ferris, was once possessed by a creature made entirely out of love called the Predator. He gave her a LiteralSplitPersonality, in this case separating her masculine side from her feminine side. His ultimate plan was to achieve this trope, but it didn't work out, largely because the male version of Carol turned out to be a creepy stalker.
* The ''ComicBook/UltimateSpiderMan'' version of Spider-Woman is a female clone of Peter Parker who has all of his memories. As she and Peter are about to part ways, the two of them share an "awkward hug".
-->'''Ultimate Spider-Woman:''' For the record, I'd regard it as masturbation. Just saying.
* This may not be a literal application of the trope, but when Most Excellent Super-bat of the ComicBook/SuperYoungTeam met a young woman cosplaying as him, he felt he couldn't pass up the opportunity to get with her. He claims it was the simple fact that there are people out there who practically worship him that got him so turned on, but it's hard to not see it as an exercise in narcissism.
* In the 2011 ''Series/{{Dollhouse}} Epitaphs'' mini-series, an Ivy imprint in a male body and an Ivy imprint in a female body are seen hooking up, though Alpha (with whom the Ivy imprints are trying to raise an anti-Rossum army) interrupts them before they can get fully undressed.
* Fantomex and Cluster in ''Uncanny ComicBook/XForce''. Slightly odd situation; Fantomex was originally a mutant with three brains, and a medical incident resulted in each brain being given its own clone body, one of which (Cluster) was female. So in a sense they're the same person.
* Dr. Manhattan in ''ComicBook/{{Watchmen}}'' almost winds up in a three-way involving himself, Laurie, and himself, but Laurie was [[{{Squick}} squicked out]] by it (it doesn't make her any happier to discover that he's got more copies working on his experiments in the other room at the same time). Strictly speaking this is not ''quite'' the trope, since it's obvious that he doesn't really care one way or the other about sex and is just doing it because he thinks it will make Laurie happy. However, with that in mind it's plausible that it could have wound up squarely in this trope had Laurie given him positive feedback.
* In the ''Survival Geeks'' story "Geeks Fatales", when our heroes meet their counterparts from a gender-flipped universe where ''Series/{{Firefly}}'' got at least three seasons, boy Sam starts to ask girl Sam if she'd ever wondered... Girl Sam angrily cuts him off and storms out. In the very next panel, [[{{stoner}} Rufus and Ruby]] are already making out.
* ''ComicBook/{{Zombo}}'': Agents Ying and Yang are both split from the same person. When one of them is killed, his other self reminisces about how they had sex together.

[[folder:Comic Strip]]
* The comic strip "Duplicity" that ran in the final issue of ''Amberzine'' told the tragic tale of a women who had an affair with a male shadow of herself in [[Literature/TheChroniclesOfAmber the Amber universe]].

[[folder:Fan Works]]
* Enough artwork on Website/DeviantART depicts this to last a viewer ''years'' if they're into such stuff.
* Pictured above is fanart containing three versions of Setsuna F. Seiei from ''Anime/MobileSuitGundam00''. However, the show lacks any ways to make it actually happen.
* A throw-away line in the ''FanFic/TotalDramaDoOver'' series, has an off hand line from Zoey to her then boyfriend Mike about Vito popping up.
** (They all laugh. Mike gasps into Vito)
** Mike/Vito: AYO! Those were my glory days ya talkin bout. The girls couldn't get nuf' of me! (Mike/Vito scoots towards Zoey) Especially THIS babe.
** Zoey: (narrows her eyes at Mike/Vito) Aren't you currently in a relationship with Svetlana, Vito? (Mike/Vito goes wide eyed)
** Mike/Vito: Ugh… why'd you like to ruin mah fun, huh? (gasps back to Mike)
*** It's truly bizarre because Vito and Svetlana are alternate personalities of Mike, who in turn is an alternate personality of [[spoiler: Mal]]
* Pick a film/TV series. Guaranteed there's at least one fic out there of a character screwing [[DoppelgangerCrossover a different character that actor has played.]] Which is sort of like screwing yourself.
** ''Series/StarTrekVoyager'':
*** The fandom wound up with this due to the actor for Tom Paris having been on ''Next Generation'' as an [[YouLookFamiliar entirely different character]]. So a lot of fanfic winds up with the two characters meeting up in some bar, drunk. (Or, alternatively, just doing a RecycledScript of someone else's fic with Tom being such a narcissist he heads to the holodeck to copy himself.)
*** Then there is all the times ''Voyager'' crewpeople have met duplicates of themselves. Or not met the duplicates of themselves. They really do give the actors lots of roles to play.
** There are tons of [[Film/RedEye Jackson Rippner]] / [[Film/TheDarkKnightSaga Jonathan Crane]] fics out there; Cillian Murphy on Cillian Murphy action. At least one person has actually thrown Jim from ''Film/TwentyEightDaysLater'' (also played by Murphy) into it...
** ''Series/DoctorWho'':
*** There's an R-rated [[Series/DoctorWho Ninth Doctor]]×[[Series/{{Heroes}} Claude Rains]] fic out there (both played by Creator/ChristopherEccleston). It is... '''surreal'''.
*** As well as quite a few [[Series/DoctorWho Tenth Doctor]]×Series/{{Casanova}} tales. Although this was pretty much inevitable, [[Creator/DavidTennant considering the actor in question.]]
*** Although never even hinted at in-series, the use of [[TheNthDoctor "regeneration"]] in ''Series/DoctorWho'' and the propensity for the Doctor to meet his past selves has all the inevitable implications. There is even an entire livejournal community [[http://community.livejournal.com/timeslipping dedicated to exactly this.]] There are so many works devoted to relations between the tenth Doctor and the copy regenerated from his preserved hand that they have their own trope name: Tencest.
* ''Franchise/MarvelCinematicUniverse'':
** [[Film/CaptainAmerica Steve Rogers]]/[[Series/PoliticalAnimals TJ Hammond]]/[[Film/CaptainAmerica Bucky Barnes]] is a surprisingly popular threesome
* [[http://fav.me/d2bwxnf Ladies and gentlemen,]] I give you Film/HarryPotter!Creator/HelenaBonhamCarter × [[Film/SweeneyToddTheDemonBarberOfFleetStreet Sweeney Todd]]!Creator/HelenaBonhamCarter.
* Any character with a split personality (especially where the other half is a {{Bishonen}}), such as H/Allelujah from ''Anime/MobileSuitGundam00'', ''Manga/DNAngel'' or ''Manga/YuGiOh'', will be given this treatment in some niche of whatever fandom the character appears in. Explicitly, said "characters" in one body (like Allelujah and Hallelujah) will instead be two separate characters all together, and... will make music together. And this is not restricted to anime.
* Especially ''Anime/YuGiOh''
** Perhaps the most popular pairing in the fandom is Yugi and Yami. Add in Yami's past self Atem for a threesome. There's also Bakura and "Ryo", and Marik and "Malik", fanon names for the evil and good sides of the characters. Kaiba and Set (his past self) is also popular.
** The ''Anime/YuGiOhGX'' fandom has something called Monochromeshipping, which pairs up Season 3 Manjuome Jun with... [[BrainwashedAndCrazy Season]] [[EvilCostumeSwitch 2]] [[LightIsNotGood Manjoume]] [[RivalTurnedEvil Jun]] (however, in most fanfiction, whatever happens between the two Juns happens purely [[AllJustADream in his head]].)
** There's also Thundershipping, which pairs [[Anime/YuGiOhGX anime!Manjoume]] with [[Manga/YuGiOhGX manga!Manjoume]]. Judai×[[SuperpoweredEvilSide Haou]] and Johan×Possesed!Johan are also fairly common.
** Fire up again after the sequel series ''Anime/YuGiOhArcV'' aired, because the show used AnotherDimension and IdenticalStranger. Fanfics exists for any combination of Yuya / Yuto / Yugo / Yuri and Yuzu / Serena (or sometimes even all of them).
* ''Manga/KatekyoHitmanReborn'':
** Besides canon (see above), there are all those fanworks that pair up the boys with their [[TimeSkip "ten years later"]] versions of themselves... there's even official art of the characters together with their older selves. [[RuleThirtyFour Undoubtedly there's also a fanart/fic]] pairing the cast with the first generation of Vongola family. [[GenerationXerox Who look almost exactly like the tenth generation.]]
** Pairing the hero Tsuna in [[SuperMode Hyper Dying Will Mode]] with Tsuna in his normal state is far from uncommon.
* It's an old question in ''ComicBook/{{Legion of Super-Heroes}}'' fandom whether Triplicate Girl sleeping with herselves would be [[{{Twincest}} incest]] or masturbation...
* Lavi and Deak from ''Manga/DGrayMan''. Also, [[spoiler: Allen and the Fourteenth Noah]]. And I've actually seen a fic where Allen was paired with his innocence.
* The title character of ''Manga/{{Naruto}}'' is technically able to create a clone of himself--of the [[OppositeSexClone opposite gender]] to top--and the fans haven't ignored its [[PowerPerversionPotential potential]]. It's called the Harem Jutsu for a reason.
* ''Manga/RanmaOneHalf'':
** Lemon fics use this with Ranma's male and female sides. Some would say [[{{Squick}} far too often]]; others would say not often enough. There is even at least two MindScrew fanfics where it is revealed that, thanks to some TimeTravel, Ranma is both his own father ''and'' his own mother... (One where he's actually both Genma and Nodoka, and another where he gives himself up for adoption to the Saotomes.)
** It's not always strictly limited to Ranma(s). Other characters can get on with themselves, either through alternate universes, or with creative use of the Spring of Drowned Twins (usually the "instant", i.e. temporary, powder form), adding a dose of Instant Drowned Male/Female water to make the pairing heterosexual.
* This can be argued as the case of the fanshipping of Luc and Sasarai in ''VideoGame/{{Suikoden}}''. While they are PolarOppositeTwins in terms of personality and their canonical relationship more closely resembles CainAndAbel, the fact that they are cloned ArtificialHumans of their father means that they are genetically identical, making any pairing with them riding the line with this trope.
* Youko Kurama×Shuuichi Kurama is seen occasionally in ''Manga/YuYuHakusho'' fanfic, but they're not usually portrayed as the same person.
* There is a really bizarre (pun completely intended) ''Manga/JoJosBizarreAdventure'' lemon which included Will×Gyro and Jonathan×Johnny pairings. May or may not count though as Gyro and Johnny are their alternate universe incarnations, but look and act very different.
** There are many pairings which involve Stands and their users being together.
** [=DiavoloxDoppio=] also has a few pieces of fanart dedicated to it.
* ''Franchise/StarTrek'':
** There's William T. Riker's transporter clone W. Thomas Riker, who has the advantages of being A) one of the vanishingly rare ''Star Trek'' duplicates who is ''not'' remerged, killed, or returned to his home universe at the end of the episode, and B) Jonathan Frakes. Creator/AndrewHussie and Jan van den Hemel [[http://www.youtube.com/watch?v=Ck-VIA1GUCY managed to use]] ManipulativeEditing on some episodes of ''Series/StarTrekTheNextGeneration'' to make this come true on screen.
** Goatee!Spock from the MirrorUniverse is the other major example of a duplicate character left kicking around after his episode. Considering that Spock is one half of the pairing that ''originated the term {{Slash}}''...
** Not to mention Nu!Spock×Spock Prime on the ''Film/StarTrek'' Kink Meme. Oh, yes, it's happened. But after all, this is [[CrackPairing the]] [[NotSafeForWork kink]] [[BrainBleach meme]] we're talking about. There is also Nu!Kirk×Kirk Prime, and possibly others, but the two Spocks do have the advantage of already being in the same universe.
* ''LightNovel/HaruhiSuzumiya'':
** Various doujins of ''[[LightNovel/HaruhiSuzumiya The Melancholy of Haruhi Suzumiya]]'' have this. Specifically, Mikuru and her future self, [[TwinThreesomeFantasy with some help from Kyon]].
** Pairing the characters with their ''Fanfic/SuzumiyaHaruhiNoSeitenkan'' [[GenderFlip counterparts]] is surprisingly common, with Kyon and Kyonko being by far the most favorite.
*** One of the well-known example is ''[[FanFicRecs/HaruhiSuzumiya Tea of Sagittarius series]]'', where the original Kyon is accidentally genderbent into a female version, [[spoiler:which made Haruhi almost freak out in happiness to the point that Mikuru and Itsuki suffers same fate]]. Long short story, Haruhi unconsciously summons male Kyon from another world as well. [[HilarityEnsues Regadless, out of curiousity, pride, and self denial]] they began to explore the world of sexual perversion in secret, taking advantage of their current state and both insist that this would count as [[ADateWithRosiePalms masturbation]] instead. It wouldn't be [[MindScrew so bad]] if this ISN'T about [[MetaGuy Kyon & Kyonko]] [[UnreliableNarrator we're talking about]], as someone commented:
---->'''Comments:''' [[spoiler:My blowjob]] [[MindScrew can't be this]] [[AllPsychologyIsFreudian psychological]].
** In ''Fanfic/KyonBigDamnHero'', Kyon has a dream involving Mikuru and Adult!Mikuru but stops thinking about it before it goes into any detail.
* There is a ''Anime/CodeGeass'' [[http://www.fanfiction.net/s/5361224/1/The-Enemy-Of-My-Enemy-Is-My-Friend slash fic]] where Zero and Suzaku are fighting over Lelouch's affections. The author has also written other stories involving Zero/Lelouch and has admitted in one of her other slash fics that Website/FanFictionDotNet to add Zero's name to the character list for the sole purpose of writing these types of fanfiction.
* Loki fangirls tend to pair his female form with the man himself, usually his Creator/TomHiddleston incarnation. Or they just pair multiple male forms with each other, considering one of his tricks in the movies is to make multiple copies of himself. Fics make those copies tangible, of course. Since ''Comicbook/LokiAgentOfAsgard'' there are actually multiple versions of him around thanks to an impressive TimeyWimeyBall, yes, some people ship them.
* ''WesternAnimation/DannyPhantom'':
** Somehow, there are Danny Fenton×Danny Phantom pairing fan-works, even though they're the same person... at least when Danny hasn't used the Fenton Ghost Catcher to separate his human and ghost halves, that is. Some of said fanfics involve said invention, and others take place in [[AlternateUniverseFic an alternate universe]] where they're completely different people. This ship is even common enough to have not one, but ''three'' [[IdiosyncraticShipNaming names]]: Pitch Pearl is the standard name, Red Pearl is for when Phantom is [[BrainwashedAndCrazy under Freakshow's control]], and Heroic Amusement is for when the fanwork is based heavily on the episode "Identity Crisis" (which itself is likely the main reason for this ship, due to it containing an instance of Danny being temporarily split into two people).
** Then there's also Danny×[[OppositeSexClone Dani]]...
** And his [[FutureMeScaresMe future self]]. Yes, [[AxCrazy that future self.]] Before you think about that too hard, there is an actual fic for that: ''[[http://www.fanfiction.net/s/3317236/1/Narcissism Narcissism]]''. It's quite horrifying, and sadly a DeadFic.
** There's always the fact that one of his powers is actually creating duplicates of himself. And yes, one of the duplicates can go back to human with the other staying as ghost. Granted only Vlad and his BadFuture self did that, but it's only a matter of training for Danny to do it.
** This is the gimmick Danny and Sam use in the ''Fanfic/FacingTheFutureSeries'' when Sam dresses as Danny for Halloween, creeping out Tucker and Valerie.
* ''VideoGame/TheWorldEndsWithYou'' has attracted a lot of this, thanks to the implication that there are alternate universes that may be crossed.
* While the prospect doesn't exist, the fandom of ''Manga/ToLoveRu'' continues to clamor for an ''actual'' OppositeSexClone ''conveniently'' given a place in the male protagonist's {{Harem|Genre}}, due to his [[spoiler:AttractiveBentGender as a result of a TransformationRay]]. Then again, because of the female protagonist's status as a GadgeteerGenius, the likelihood of this happening isn't so far out...
* ''VideoGame/SuperRobotWars'':
** ''VideoGame/SuperRobotWarsReversal'' gives players the choice of either playing as Raul or Fiona Gureden, who's really the same person. Plenty of fanworks used this trope, but when they were brought into the ''VideoGame/SuperRobotWarsOriginalGeneration'' sub-series as HalfIdenticalTwins, it became BrotherSisterIncest.
** Kazuma Ardygun and [[spoiler:Aria Advance]] of ''VideoGame/SuperRobotWarsW'', the latter being his OppositeSexClone created by The Database. Since Kazuma holds the dubious honor of being the first OriginalGeneration in the franchise not to wind up with a LoveInterest, doujin and fan artists had a field day with this trope by pairing them together.
* Ever since ''VideoGame/TombRaiderUnderworld'', there's been an increasing number of pics with Lara and her Doppleganger from that game.
* ''[[http://www.eskimo.com/~vecna/brothers.html Brothers]]'', a ''WesternAnimation/{{Gargoyles}}'' fanfic, features multiple clones of [[MadScientist Anton Sevarius]], some of them gender-swapped, and the daughter that one pair among them decided to create the old-fashioned way as an experiment. (Note that this story occurs more than halfway through an [[http://www.eskimo.com/~vecna/gargoyles_fanfic_master_list.html extensive]] fanfic continuity.)
* ''Franchise/{{Pokemon}}'':
** There's at least one doppleganger shipping: between Ash and a [[WholesomeCrossdresser cross-dressed Ash]] and the pseudo-example of malevolent shipping: Ash and the king of Pokélantis, who takes Ash's form.
** Depending on your viewpoint, either Lyra from ''[[VideoGame/PokemonGoldAndSilver Heartgold and Soulsilver]]'' is based off the female ''Crystal'' protagonist Kris (she technically never had a canon name and looks incredibly like her) or she is a redesigned Kris. Nevertheless Lyra/Kris is a popular pairing.
** More than a few fanworks ship Red's classic design (Gen 1-Gen 2) with his modern one. Red's {{fanon}} design ([[FanNickname Pixiv!Red]], [[MemeticBadass Uber!Red]]), and occasionally a cross-canon counterpart like Ash from [[Anime/{{Pokemon}} the anime]] or Red from ''Manga/PokemonAdventures'', have been added into the mix.
** Due to the ability to choose between three designs of Calem and Serena from ''VideoGame/PokemonXAndY'' people have begun shipping the canon design, AmbiguouslyBrown design, and blue eyed design.
* Website/ThatGuyWithTheGlasses:
** In the fandom, both WebVideo/TheNostalgiaCritic×WebVideo/{{Ask That Guy|WithTheGlasses}} and [[WebVideo/TheSpoonyExperiment Spoony×Dr. Insano]] are extremely popular. For the former, [[MindGameShip dub-con]] and MindRape are pretty much par for the course (it's also been made into {{incest|IsRelative}}) and while the latter isn't so bad because of Insano's [[TheWoobie woobie-dom]], it's usually presented as innately creepy.
** And [[WebVideo/AtopTheFourthWall Linkara×Mechakara]]. As you can probably tell from how Mechakara is in canon, it's also insanely disturbing. Technically [[spoiler:Mechakara only looks like Linkara as part of a disguise. Proper selfcest would be [[RobotBuddy Pollo]]×Mechakara.]]
* One ''Franchise/SailorMoon'' fanartist and fanfiction writer, Bill K., lets Sailor Pluto have some fun this way, with several time-traveling future selves.
* ''Franchise/KingdomHearts''
** The series has a strangely huge potential for this ([[RuleThirtyFour and don't think for a second fandom hasn't picked up on this]]), with Riku and the Riku Replica, Demyx and his waterclones, Xemnas and Xehanort's Heartless (heck, why not Xehanort himself?), Roxas and Sora, Kairi and Namine, and most recently, Sora and [[spoiler:Xion]]. And Roxas and [[spoiler:Xion]]. [[OverusedRunningGag And]] Sora, Roxas, and [[spoiler:Xion]], for a ''threesome'' of selfcest.
** There is a good chance the whole Roxas, [[spoiler:Sora, Xion]] thing could go even further with Ven, who undoubtedly is in some way "the same being" as [[spoiler:Sora×Roxas×Xion]], given his appearance and voice being absolutely identical to Roxas'. So now we have [[spoiler:foursome]] potential, although this assumes they can all co-exist, but we don't know yet for sure if that can potentially happen. [[spoiler:And Vanitas makes five.]]
** There's also the innumerable stories and drawings which pair the Squaresoft [[{{Expy}} Expies]] from ''Kingdom Hearts'' with their original inspirations.
** Just for a compelte list: the past and present versions of Mickey and Pete, Vexen and Vexen Replica[[TwinThreesomeFantasy (s)]], Sora and Anti-Sora, Roxas and Shadow Roxas, Donald, Goofy and Sora's Master Form (technically), Roxas and Ven, [[FoeYay Vanitas and Ven]], the real and virtual versions of Hayner, Pence, Olette, Seifer, Vivi, Fuu, Rai, Setzer and Kingdom Hearts itself. In ''Final Mix'', there's the real and virtual versions of everyone in Organization XIII, and Larxene and Zexion's copies...
** Xemnas and Saix, who are actually a very popular fan pairing, are basically this [[spoiler: since Saix is possessed by Xehanort.]] Strangely, the fans don't seem to have picked up on this.
* ''VisualNovel/AceAttorney'' series:
** Diego Armando×Godot. The game had some people believe that Diego and Godot are twins, at least before the reveal. The obvious difference in their looks was explained with partial albinism, which is known to cause problems with eyesight along with the obvious white hair. And as no-one knew what colour Godot's eyes were and fangirls are prone on jumping the gun...
** On a more lighter side, but still pretty creepy, is fanart of crossovers between [[MirrorUniverse the US and Japanese counterparts]]. Phoenix (US) seems to be always portrayed as enjoying Ryuichi's (JPN) company [[HoYay a little TOO much]]...
** And all the [[spoiler:scarred Matt Engarde×"refreshing like a spring breeze" Matt Engarde]]. There's even a popular dôjinshi devoted to them gang-banging Edgeworth.
** Mia. Original, Maya-style or Pearl-style. The third iteration gets a little creepy when one remembers that the channeler is a pre-schooler.
** And in the grand tradition of people × their alternate identities, we now have [[spoiler: Calisto Yew×Shih-na.]]
** Those watching the Takarazuka musical often ship Miles Edgeworth×The Miles Edgeworth Backup Dancers, all of whom dress and look exactly like him.
** [[BunnyEarsLawyer Phoenix]], [[OlderAndWiser Hobo Phoenix]] and [[CrouchingMoronHiddenBadass Feenie]]. Sometimes they also throw [[AdorablyPrecociousChild Kid Nick]] into the mix.
** And now there's Edgeworth/Bratsworth (Edgeworth's 20-year-old self seen in a flashback) and [[GenkiGirl Younger Ema]]/[[TookALevelInJerkass Older Ema]].
* ''VisualNovel/FateStayNight'' has this trope in the form of pairing Shirou x[[spoiler:Archer]]. Oh, and let not forget about [[spoiler:Avenger]] too, though ''technically'' [[spoiler:Avenger was just borrowing Shirou's form]]. The fanfic other hand, also have "Shirou Kotomine" (parallel world Shirou raised by Kirei).
* ''Franchise/TheLegendOfZelda'':
** Sheik/Zelda is popular despite Sheik literally being Zelda crossdressing ([[FanonDiscontinuity near all fanfics ignore this]] and write her as being [[GenderFlip biologically male]] and her own character). ''VideoGame/SuperSmashBros'' added fuel to the fire by seperating Zelda and Sheik; at least one fic has shipped them as [=OOT!Sheik=] and [=TP!Zelda=]. Tetra/Zelda, less so for some reason. Tetra/Sheik practically doesn't exist (and [[GenerationXerox technically]] doesn't count)
** On the other hand, surprisingly little ''VideoGame/TheLegendOfZeldaFourSwords'' hentai exists. But why write selfcest when the ''[[Manga/TheLegendOfZeldsFourSwordsAdventure official manga]] itself'' is [[HoYay already catering]] to the pairing (Red/Blue Link, to be specific)? Freud would love to read that one.
** Dark Link and regular Link (of any game/universe) are paired together so often it long ago stopped being funny.
** There is fanart of ''Wind Waker'' Link and young ''Ocarina of Time'' Link. Also of ''Twilight Princess'' Link and adult ''Ocarina of Time'' Link. And for the ones who want to cross over to [[LoliconAndShotacon shotacon]] territory, there's always a combination of the two... including both versions of ''Ocarina of Time'' Link together. However, the only one of those that is Screw Yourself is the ''Ocarina of Time'' Links, as the others are just expies, [[IdenticalGrandson identical great-great-(etc)-grandson]], or GenerationXerox.
** Linkcest is exceedingly common on the slash side of the fandom. The classic Link's are almost always ignored in selfcest works, with a focus being on the ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', ''VideoGame/TheLegendOfZeldaTwilightPrincess'', and ''VideoGame/TheLegendOfZeldaSkywardSword''. As mentioned they're technically assumed to be related but at the same time are reincarnations of each other. Signs point towards the ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' Link having a good chance of being popular for Linkcest in the future.
** Somewhere between IncestIsRelative and selfcest, shipping the Sleeping Zelda from ''VideoGame/ZeldaIITheAdventureOfLink'' and classic Zelda from ''VideoGame/TheLegendOfZeldaI'' is a possibility (though people usually add [[OneTrueThreesome Link into the mix]]) due to them canonically co-existing together. It's assume Zelda is a descendant of the Sleeping Zelda's brother and not a reincarnation--because how can you be reincarnated from someone who isn't even dead?
** Hilda/Zelda and [[spoiler:Ravio/Link]] from ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' is dangerously close to selfcest. They're technically counterparts but have enough comparisons to blur the lines.
* The 2012 movie version of ''WesternAnimation/TheLorax'' had only been in theaters less than a month before the internet was swarmed with fanart/fanfiction/fanWHATEVER between the Young!Once-ler and The Onceler, nicknamed "The Greedler" (after he becomes successful). The cute little pairing name for it? [[http://www.tumblr.com/tagged/oncest Oncest]]. The Lorax fandom has elevated this to an art form, with Tumblr blogs consisting of every possible AU and personality for the Onceler, and all of them are shipped together. At this point it's no longer the Lorax fandom, its the Onceler fandom.
* There is a hella lot of Prince×Dark Prince from ''VideoGame/PrinceOfPersiaTheTwoThrones''.
* It's not a main pairing, but there are some [[spoiler: Leon/Judas]] works in the ''VideoGame/TalesOfDestiny'' fandom.
* In ''VideoGame/TalesOfTheAbyss'' we have [[CloningBlues Asch and Luke]]. There are plenty of fanfics pairing them together. And then there's [[spoiler:Sync×Ion×Florian]]... Fandom has affectionately dubbed this particular brand of Screw Yourself "Replicacest."
* ''VideoGame/BreathOfFireIV'' (unsurprisingly) has a prodigious amount of [[spoiler:Fou-lu×Ryu]] fanart and fanfic--to the point that this pairing has earned not one but ''two'' {{Fan Nickname}}s: [[spoiler:[=FouRyu=] and Yorae Dragon Masturbation Fanwork]]. This is only encouraged by the fact that the two are a LiteralSplitPersonality and that there is a manga adaptation ongoing in the same manga magazine running ''Vassalord''. By the same company that was responsible for ''Manga/PeacemakerKurogane''. If this isn't brain-breaking enough, [[spoiler: consider that Fou-lu is strongly implied to have a romantic interest with a woman who cared for him and ultimately was murdered in an attempt to literally nuke him, leading to the FanNickname of [=FouMami=] for the ''second'' most common pairing in the ''[=BoF=] IV'' fandom. And yes, there is a decently large chunk of the Japanese fandom in particular who writes both [=FouMami=] ''and'' [=FouRyu=]. Particularly involving ''comfort selfcest''.]]
* Courtesy of his visit to the post-apocalyptic future, Dean Winchester of ''Series/{{Supernatural}}'' gets this in fics, both in the form of Dean×[[FutureMeScaresMe future!Dean]] and Dean×future!Dean×[[BrokenAngel future!Castiel]].
* ''VideoGame/MegaMan'':
** The Japanese ''VideoGame/MegaManStarForce'' fandom is full of Pat×Ray fanarts.
** ''Classic'' has Gemini Man, a narcissist with the ability to clone himself. The implications aren't lost on fandom.
** Meanwhile, the Vent×Alie pairing was fairly popular for ''VideoGame/MegaManZX'', before ''Advent'' came out. The jury is still out on whether that counts as this trope or BrotherSisterIncest.
** ''VideoGame/MegaManZero'' has one as well: [[spoiler:Zero×Omega, Omega having Zero's original body.]]
* This works with {{Alternate Continuit|y}}es too. There exists some fanarts pairing the original [[LightNovel/DirtyPair Lovely Angels]] with their ''Anime/DirtyPairFlash'' counterparts. Sometimes adding the Adam Warren versions for variety.
* Flippy×Flippy is surprisingly popular within the ''WebAnimation/HappyTreeFriends'' fandom.
* Music/{{Vocaloid}} fanfiction and fanart tends to use this trope, mainly because the fandom likes creating {{Opposite Sex Clone}}s of the official characters. A favorite pairing is Len×Rin, an official pair of HalfIdenticalTwins, which tends to overlap this with BrotherSisterIncest. And even ''they'' have their own fanmade gender-swapped clones, who actually ''don't'' look like just a second pair of the originals.
* ''Literature/HarryPotter'':
** There has been several fics [[labelnote:*]]''Hermione Plus'' and ''Time Alone with Herself'' on Adult Website/FanFictionDotNet, among others[[/labelnote]] involving Hermione, um, misusing the Time Turner in this manner.
** Don't forget polyjuice potion. "Hey, Hermione, give me a strand of your hair..."
* The ''Series/WizardsOfWaverlyPlace'' fic ''[[http://www.fanfiction.net/s/5134060/1/Selfportrait Selfportrait]] has Alex having sex with a doppelganger she created [[ExactlyWhatItSaysOnTheTin in order to paint a portrait of herself]].
* ''Franchise/PowerRangers'':
** In many, many, MANY ''Series/PowerRangersSPD'' fics, the fact that Z can create duplicates comes to the fore for just such a reason.
** [[Series/MightyMorphinPowerRangers Tommy Oliver]] is sometimes paired with his clone/ancestor Tom. There's even a few fics that are threesomes of Tommy, Tom, and the White Stranger.
* ''Manga/DeathNote'' fandom has a small but dedicated contingent which ships Kira Light with [[spoiler:mindwiped Light]], in an EnemyWithin-style thing.
* ''Webcomic/AxisPowersHetalia'':
** Himaruya's liberal use of opposite-gender counterparts and [=AUs=] in his own work, along with the possible nature of civil wars and so on, has led to some selfcest fics.
** One increasingly popular fanon pairing is Prussiacest, which basically pairs Prussia either with a copy of himself or his Nyotalia counterpart. The logic behind it being that only Prussia is awesome enough to be with Prussia.
* In one ''ComicStrip/CalvinAndHobbes'' arc involving time travel, [[MyFutureSelfAndMe Calvin and his future self]] both end up taking off in the time machine leaving two Hobbeses alone. There's at least one comic floating around the Internet that... um... focuses on what they get up to in the meantime. BrainBleach is mandatory.
* Even ''VideoGame/{{Mother 3}}'' isn't safe from this. [[spoiler:There is a fanbase for [[{{Keet}} Claus]]×[[{{Cyborg}} The Masked Man.]]]]
* ''Anime/NeonGenesisEvangelion'':
** Rei Ayanami has a few dozen identical clones of herself stored in an LCL tank. She is the resident InnocentFanserviceGirl. This has lots of potential...
** There is a fic (''[[https://www.fanfiction.net/s/4652394/4/NGE-Bloodlust NGE: Bloodlust]]'', chapter four) including a scene where a clone vampirificates another and the two celebrate the occasion by playing with each other.
** And [[http://www.fanfiction.net/s/4594095/1/Reis_Daydream another one]] where Rei gets bored during class and starts fantasizing about her being replaced by one of her clones without her being told about it. Since one of them has to be eliminated, they hold a lesbian version of a last supper...
** {{Slash Fic}}s featuring different versions of Kaworu (TV series, manga, ''Anime/RebuildOfEvangelion'') are not uncommon.
* There's less of this from ''VideoGame/{{Touhou}}'' fandom than one would expect from a fandom full of SelfFanservice.
** What does exist involves interaction between counterparts from PC-98 and Windows continuities, the canon doppelgangers in ''Phantasmagoria of Dim. Dream'', and the characters who can use [[DoppelgangerAttack body doubles to attack]] (''especially'' Yuuka and [[ReallySevenHundredYearsOld Flandre]]). Or [[RealityWarper Yukari]] could just be fooling around again.
** Youmu (a [[HalfHumanHybrid half-ghost]] with a one human and one ghost body) can pull it off with or without magic, and it's been done to various degrees. And remember, in canon her ghost half can be altered into a copy of her human half. We will leave the rest to your imaginations.
* ''[[http://www.fanfiction.net/s/2285033/1/Nebula_Nostrum Nebula Nostrum]]'', an ''Literature/ArtemisFowl'' fanfic that features Opal×Lili×Opal×Lili, essentially making it a [[LesYay slash]] clonecest love quadrilateral.
* ''Franchise/ProfessorLayton'' rarely (since the ship has a paedophiliac nature) but still has the two Lukes of the third game, the little!Luke who is familiar to anyone who keeps up with the series, and his future self: big!Luke. [[spoiler:Subverted when you discover "future Luke" is a sham.]]
* ''VideoGame/CrusaderKingsII'' has one infamous but now patched GoodBadBug where random events from lusty characters forgot to check that the subject and target weren't both the same. This resulted in events where a character seduces or rapes themselves impossibly. Making matters better (or worse) this could [[HomosexualReproduction result in the king becoming pregnancy after raping himself]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** From the fandom, we have [[http://twilightflopple.deviantart.com/art/Cheer-Up-Pinkamina-210635747?offset=50 Pinkie/Pinkamena]].
** There's a fanfic, ''Fanfic/OnACrossAndArrow'', features the Mane Six travelling to an alternate universe where [[RuleSixtyThree everyone who's female is male and vice versa]], and features Fluttershy, Rarity, and Rainbow Dash falling for their male counterparts. Also heavily implied to be the case between Princess Celestia and her counterpart Prince Solaris.
** There's also ''Giving Love a Helping Hoof'', which [[spoiler:has the mane 6 meet their [[RuleSixtyThree male counterparts]] because of an anomaly in the Elements of Harmony, forcing Princess Celestia to create male versions of not only the mane 6 but Luna and herself as well to keep the balance in Equesria (and Solaris and Artemis just for the heck of it).]]
** There's a considerable amount of fan art and fan fiction that turns Trixie's narcissism as seen in the show UpToEleven. Much of it involves either Trixie fantasizing about herself with the aid of a mirror or using clones produced through magic, but in [[http://www.fimfiction.net/story/5710/1/trixies-favourite-pony/chapter-1 one parody fanfic]] she ended up having a [[ThreeWaySex 5-way]] with her reflection, a clone, a future version of herself, and a [[RobotMe robot with her likeness]]. And to further complicate things, the story closed with a [[OppositeSexClone male version of her]] from a parallel universe walking in.
** ''[[http://www.fimfiction.net/story/51693 Twilight Sparkle vs. The Bootstrap Paradox]]'', a CrackFic where Twilight has sex with her "one-week-in-the-future" self seen in [[http://tvtropes.org/pmwiki/pmwiki.php/Recap/MyLittlePonyFriendshipIsMagicS2E20ItsAboutTime "It's About Time"]]. A similar thing happens in ''[[http://www.fimfiction.net/story/159311/private-time Private Time]]''.
** ''Fanfic/TheManySecretOriginsOfScootaloo'' parodies this by having [[Series/DoctorWho The Professor]] reveal that Scootaloo and her ''Fanfic/OnACrossAndArrow'' counterpart Rollalong are the twin children of Pinkie Pie and Berry Bubble, who threw a "party" when locked in a broom closet.
** And then we have ''[[http://www.fimfiction.net/story/9562/Perfect-For-Me/ Perfect for Me]]'', which is part hilarious, part bizarre. It's about Twilight creating a clone of herself to help solve a series of time crunches. Then the Twilights start to fall in love with each other. Yeah, it's a strange story.
** In ''Fanfic/DiariesOfAMadman'', Doppel (a changeling) scares off Rainbow Dash by coming onto Rainbow while taking her form.
** Implied in a [[http://mariokidd319.deviantart.com/#/d4xsav5 fan comic]], where OC Kidder is nearby a Changeling version of himself and says "Now, neither of us will be vergins! [[RougeAnglesOfSatin [sic]]]"
** Also implied on another MLP fan post [[http://thecoopontlc.tumblr.com/post/49639177982/i-i-i-o-o done on tumblr]], which ends with [[BlackComedyRape surprise cunnilingus.]]
** The fandom generally paints background pony Cloud Kicker as a LoveableSexManiac. When circumstances result in a [[spoiler: Changeling [[ModeLock modelocked]] into Cloud Kicker's shape]] at the end of Fanfic/EakinsHardReset, this trope is implied.
-->'''Cloud Kicker:''' ''Oh, and tell me to go buck myself. I have an amazing retort for that now.''
** ''FanFic/AChanceMeetingOfTwoMoons'': Apparently, Celestia and her human counterpart have done this. Ditto for Solaris and ''his'' human counterpart, whom Solaris claims initiated it.
** Unsurprisingly, adding a semicanonical linked universe with human doubles for everypony has added to this. The most common candidates for this approach seem to be Rainbow Dash (who can tolerate her own ego) and Fluttershy (combining a touch of xenophilia with being her most easily trusted potential partner). The most common almost-candidates being Trixie (who usually can't get along enough with herself but is very likely to try anything which promises "more Trixie") and Twilight (who due to the shows' different audiences was arugably written with a mild fetish for humans or being human, but is more attracted to [[TwinThreesomeFantasy any existing Twilight x Sunset relationship]] than herself directly).
*** Author Sporktacles wrote a case in which Sunset is the product of an accidental case of this (the counterparts really didn't recognize each other). While a CrackFic, it's one of the better explanations for the absence of a human Sunset (as pony Sunset ''is'' human Sunset), why Sunset had so little trouble [[VillainsBlendInBetter thriving in a new world]], and why Celestia really didn't want Sunset playing with the mirror just yet.
* ''Franchise/SonicTheHedgehog'':
** One of the infamous Robotnik comics from Website/FourChan features this.
** [[FoeYay Sonic and Scourge]] also seems popular with the fandom. Scourge is Sonic from a MirrorUniverse who recently TookALevelInBadass who wears cool leather and has cool scars, along with being very popular with the fanbase (and fangirls especially), so its unsurprising the fanbase made SlashFic of them.
** Shipping the Classic and Modern versions of characters (mostly Sonic) isn't too uncommon.
** Many ''ComicBook/SonicTheComic'' fans, and even non-fans, ship Super Sonic and Sonic. This is because Super Sonic is a SuperpoweredEvilSide that later separated from Sonic.
* ''VideoGame/{{Persona}}'':
** ''VideoGame/{{Persona 4}}'' fandom: Shadow-on-human action? There's a pretty huge chunk of YaoiFangirls who will slash Yosuke with himself, or Kanji with his ArmouredClosetGay, or Teddie with his nihilism, or even the MC with his shadow, though he never had one... And, of course, people with other people's shadows, or others' shadows AND the human, out of some forced yet plausible {{Twin Threesome Fantas|y}}ies. This all applies to the girls too (such as [[ActionGirl Chie]] and [[WhipItGood Dominatrix Bananahead]]), but it's just more prominent among YaoiFangirls. On second thought, it's not so much screwing themselves rather than aspects of themselves... but we'll save the philosophical implications for another day.
** Naoto×Shadow Naoto is one of the more popular Human×Shadow pairings.
** And its predecessor ''VideoGame/{{Persona 3}}'''s most popular yaoi pairing is Minato×Ryoji. [[spoiler:Take note that Ryoji is supposed to be a part of Minato]]. This also applies for Ryoji×Female Protagonist shippers.
** Or Minato x Female Protagonist
* Since her creation in Phase 3 of Music/{{Gorillaz}}, Cyborg!Noodle has naturally appeared in fanarts where she's making out with Real!Noodle.
* When Dante in ''[[VideoGame/DevilMayCry Devil May Cry 3]]'' gained the Doppleganger ability, it gave the fangirls an excuse to do this. Not that Dante didn't have enough problems ''already'', given that he has [[{{Twincest}} Vergil]] pestering him.
* ''VideoGame/StarCraft'': An artist on Website/DeviantArt was badgered into producing this [[http://crimm-art.deviantart.com/art/I-think-I-just-died-a-little-255410661?q=gallery%3Acrimm-art&qo=2 image]] involving Zergified!Kerrigan and Terran!Kerrigan. For all intents and purposes she seems quite disturbed by having actually drawn it.
* If we assume that in ''Manga/{{Bleach}}'', the [[SuperpoweredEvilSide Inner Hollow]] is a part of a shinigami's soul, [[http://anhellica.deviantart.com/art/ArtTrade-Hichigo-and-Ichigo-206852560?q=boost%3Apopular%20ichigo%20hichigo&qo=36 Ichigo×Hichigo]] pairing is basically this. The same goes for shipping any [[http://anhellica.deviantart.com/art/dreaming-in-the-snow-264121596?q=boost%3Apopular%20zangetsu%20ichigo&qo=114 shinigami]] with his or her [[http://anhellica.deviantart.com/art/Hyorinmaru-and-Hitsugaya-167077287?q=gallery%3Aanhellica%2F23690553&qo=26 zanpaktou]].
* ''VideoGame/TeamFortress2'', having two teams only seperate in team colour, is naturally rife with this. For some reason Scout is the one who gets it worst.
* From ''Anime/DragonBallZ'', there is [[http://dragonkink.livejournal.com/721.html?thread=633809#t633809 Future Bulma×Bulma]] as well as [[http://mirai-masenko.deviantart.com/gallery/?offset=24#/di6ge5 Future Trunks×Trunks]]. Both pairings are technically possible in-universe, thanks to Bulma being a genius and inventing a time-machine.
** ''Anime/DragonballSuper'' has [[spoiler:Goku Black and Zamasu]] as a popular CrackPairing, despite alternate timeline versions of each other. It helps that they're both [[{{Narcissist}} colossal narcissists]] and already have a VillainousFriendship.
* Anders from ''VideoGame/DragonAgeII'' is sometimes paired with his SuperpoweredEvilSide, Justice/Vengeance.
* While Elliot and his OppositeSexClone Ellen from ''Webcomic/ElGoonishShive'' would rather avoid thinking about it in the webcomic, there are naturally {{Rule 34}} pics of them together.
* ''Webcomic/{{Homestuck}}'':
** Quite common in the fandom, particularly with the Time players whose powers include StableTimeLoop formation. Dreambubbles allow characters to contact alt-universe dead versions of themselves in their sleep. With the way the trolls' BizarreAlienBiology works, ancestor/descendant pairings may or may not have hints of this, though it's closer to incest; ancestors and descendants are born centuries apart and happen to have very similar genetic makeup.
** Definite mention of the ancestor/descendant version in ''Fanfic/{{Hivefled}}''. AbusiveParents with boy-girl twin offspring and a selfcest fetish makes for [[RapeAsDrama bad bad things]].
* ''WesternAnimation/AdventureTime'' has an in-universe Rule63 known as "Fionna and Cake", which also happens to be [[spoiler:in-universe fanfiction.]] One of the most common ships is [[TheHero Finn]] [[AdamAndEvePlot with]] his counterpart [[ActionGirl Fionna]], though Bubblegum×Gumball and Marceline×Marshall Lee are common pairings. No shipping of Finn×[[spoiler: Ice King! Finn]], though.
* ''Manga/FullmetalAlchemist'' has the popular [[SlashFic slash pairing]] of Greed (the second incarnation) and Ling-while ultimately different people, Greed shares the same body as Ling. If you want to stretch the definition, pairing any the Homunculi may count as they're emotions of Father that he removed from himself.
* ''VideoGame/DeadlyPremonition'' has a not-insignificant following for York and Zach--the main character and his imaginary friend, [[spoiler: who is technically his split personality]]. Although they technically share a body, [[spoiler: it seems to be possible for them to meet and exist in separate bodies in the otherworld that appears in their dreams]].
* A recurring theme in ''Anime/PuellaMagiMadokaMagica'' fanart is showing interactions between Homura [[FromNobodyToNightmare pre-contract and post-contract,]] often adding Madoka into the mix.
* The ''Manga/{{Saki}}'' doujin, ''[[http://www.mangapark.com/manga/saki-buchou-musou-doujinshi/v1/c16/all Buchou Musou]]'' (translated, the Unrivaled Club President), has Hisa [[LauncherOfAThousandShips paired with several major and minor characters]], and ultimately concludes with Hisa paired with herself.
* ''Disney/{{Frozen}}'':
** The popularity of the fanfics ''r9kElsa Is Suffering'' and ''A Snowflake in Spring'' and has led to [[http://dragonclaws123.deviantart.com/art/Cold-Season-r9k-Elsa-x-ASIS-Elsa-446032355 fanart shipping the]] [[http://dragonclaws123.deviantart.com/art/Elsacest-450877651 two versions of Elsa together]]. The fact that she is a CelibateHero (led to the fan writers freedom to decide what her sexuality is) and a LauncherOfAThousandShips and is able to create sentient life from her ice power does ''not'' help the matter.
** Shipping Elsa with her [[WhatCouldHaveBeen earlier]] design with the spikey short hair--[[FanNickname dubbed]] "Evil Elsa" or just "Onion" by fans--is very common. Even more common is to add [[IncestYayShipping Anna]] into the mix for an extra messed up, incest ridden OneTrueThreesome.
* ''WesternAnimation/SouthPark'': The JustForFun/PrincessKenny humor page on ''this very wiki'' has Kenny [[RunningGag continuously and repeatedly]] profess his love for his princess alter-ego from ''VideoGame/SouthParkTheStickOfTruth''. [[spoiler:[[TheyKilledKennyAgain This ends up getting him killed by the admins.]]]]
* ''WesternAnimation/GravityFalls'':
** There's more than a few fics slashing Dipper with his magic photocopier duplicate Tyrone.
** Dipper and Bipper isn't an uncommon ship.
** On the fanon side, there exists an AU called "Reverse Pines" where Dipper and Mabel are evil. Naturally, fans ship them with their canon incarnations.
* The {{NSFW}} webcomic ''Shädbase'' pairs up the adult April O'Neil from the first ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' cartoon with the teenage April O'Neil from the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 CGI cartoon]], casting them as sisters for extra fetish.
* {{Defied}} in ''Fanfic/TheWrongReflection'' when Captain Kanril Eleya walks in on her mirror universe counterpart, who's in sickbay [[ToplessnessFromTheBack stripped to the waist]].
-->'''Dal Kanril Eleya:''' (''[[SarcasmMode sarcastically]]'') See anything you like, ''Captain''?\\
'''Captain Kanril Eleya:''' I don't swing that way. Just saw you, is all.
* ''Franchise/{{Transformers}}'': A great example of the trope is the numerous fanart and fanfic of transformers (usually Autobots) somehow running into their Shattered Glass counterparts and getting... screwed. A more specific example is a work featured on Archive of Our Own and Website/FanFictionDotNet is one about Smokescreen (the young adult/late teen version from Transformers Prime), titled "Gettin Off On You Getting Off On Me". Obviously NSFW.
* ''WesternAnimation/TotalDrama'': While it's not so common, many fans enjoy pairing Mike with his [[SplitPersonality alternate personalities]] (or just pairing off the alters with each other). Perhaps the most strange of them all is shipping Mike with his [[EvilIsSexy evil alter, Mal]]. A (non-explicit) Mal/Mike fic can be read [[https://www.fanfiction.net/s/10723995/1/Nighttime-at-the-Asylum here]].
* [[Creator/DetsniyOffSkiword Kid Icarus Uprising 2: Hades Revenge]] includes this as the first event in the life of Cloud Angle's OppositeSexClone, Azul. They were intending to avoid a VirginSacrifice plot.
* Fans of ''VideoGame/ClockTower 2: The Struggle Within'' like to ship Alyssa with her male SplitPersonality, Bates.
* In the ''WesternAnimation/ThePowerpuffGirls'' fandom, when it comes to LesYayShipping it's common to ship the girls with their {{Evil Counterpart}}s from an AlternateUniverse, The Powerpunk Girls.
* The ''Film/CaptainAmerica'' fic [[http://archiveofourown.org/works/7910536 Except it Abide in the Vine]] features some multiverse comics!Bucky-on-movie!Bucky action (with illustrations). Comics!Bucky even calls it masturbation when Sam finds them obviously post-coital the next morning.
* In the aptly named fic [[http://archiveofourown.org/works/11794635 Doppelganger]], the character Clay Appuzzo from the show ''I'm Dying Up Here'' picks up the [[Film/CaptainAmericaTheWinterSoldier Winter Soldier]] for a one-night-stand. Both characters are played by the same actor.
* In the WesternAnimation/KimPossible fanfic, FanFic/AtTheCenterfoldOfTheStorm, Shego mentions that [[MesACrowd Wego]] has used his powers as [[PowerPerversionPotential 'the ultimate form of masturbation']]. [[YouDontWantToKnow Don't ask how she knows.]]
* Given that there are three paths for each character in ''VideoGame/{{Elsword}}'' this is prevalent among the characters. It isn't uncommon to see two or even all three versions of one character being paired together in fanworks.
* Adeleine and Ado from ''Franchise/{{Kirby}}'' get shipped together, usually with Ado being a boy. It was later revealed that they're the same (female) character under two different names ("Ado" presumably being because her name was too long for in-game use).
* After an entire arc centered around alternate universes (each with their own Ben) occured in ''WesternAnimation/Ben10Omniverse'', some fans began shipping Prime!Ben with his counterparts from these universes. Arguably the most popular is [=PrimeWatch=] (Prime!Ben and No-Watch Ben).

[[folder:Films -- Animation]]
* In ''WesternAnimation/TheNightmareBeforeChristmas'', Dr. Finklestein ends up creating what appears to be a wife that looks exactly like him, even sharing half of his brain. This naturally lends fuel to the AlternativeCharacterInterpretation that Dr. Finklestein created [[LoveInterest Sally]] for more carnal desires.

[[folder:Films -- Live-Action]]
* In ''Film/The6thDay'', Adam Gibson, who was cloned without his knowledge, tells the villain he should clone himself while he's still alive. The villain asks if it would be so he could get Adam's unique perspective. Adam says, "No, so you can go fuck yourself." (and when the dead villain falls over an unconscious/incomplete clone of himself, Adam's reply is "When I said you should screw yourself, I didn't mean it literally.")
* A deleted scene in ''Film/AustinPowersTheSpyWhoShaggedMe'' has Number 2 from the past and future in bed, [[SmokingHotSex smoking cigarettes]], and the older one musing that it's not technically cheating. This is based on the gag actually used at the end of the movie, with two temporally displaced versions of Austin ending up in bed with his LoveInterest.
-->'''Austin:''' Paging Dr. Freud!
* In ''Film/{{Click}}'', when we're introduced to the year 2017, a newscast can be heard in the background stating that: "Michael Jackson, the first man to clone himself, is suing himself for molesting himself." Now sadly HarsherInHindsight.
* ''Film/DrJekyllAndMrHyde''
** In several film adaptations, Jekyll and Hyde hallucinate each other and so are able to interact. Usually they fight or argue, but sometimes their actions can [[HoYay get a bit... suggestive.]] Rather appropriate given that one of the possible literary interpretations of the book is as an allegory to the double life that was necessary for Victorian-era gay men.
** The 2002 John Hannah adaptation is a prime example of this, with Hyde often getting intimately close to Jekyll, and even licking him on the cheek at one point, and in the 2008 film starring Dougray Scott, at one point Hyde pins Jekyll to the wall and kisses him. That's the farthest that any movie adaptation has ventured to go, but several fanfiction works have taken this idea even further.
* The Creator/JohnWaters movie ''Female Trouble'' stars a character played by Divine who gets raped and impregnated by a man... who is also played by Divine. She ends up homeless and she calls her baby daddy for help.
* ''Film/PiratesOfTheCaribbeanOnStrangerTides'' has Jack Sparrow kiss someone disguised as him.
-->'''Jack:''' I've always wanted to do that.
* In ''Film/{{Predestination}}'', like ''Literature/AllYouZombies'' on which it is based, [[spoiler: Jane is made pregnant by a future version of herself who went through a sex change and came back through time.]]
* ''Film/StarTrekVITheUndiscoveredCountry'': Kirk to fellow Klingon-gulag inmate Martia, who turns out to be a shapeshifter, formerly in the form of an attractive female humanoid and now in the form of Kirk himself. A bit of AdamWesting in there for Creator/WilliamShatner, playing off his perceived enormous ego:
-->'''Kirk:''' I can't believe I kissed you!\\
'''Martia:''' Must have been your lifelong ambition!
* As ''Film/Wishmaster2EvilNeverDies'' demonstrates, [[https://www.youtube.com/watch?v=n-Cgo4jPjyw it doesn't always require two people to do this]], when an evil JerkassGenie and a careless [[BeCarefulWhatYouWishFor wish]] are involved. It doesn't end well either, as the mutated lawyer literally screws himself to death.

* ''Literature/TheManWhoFoldedHimself'' by David Gerrold. The eponymous time traveler has sex with both male ''and'' female versions of himself, sometimes several at a time.
* "Literature/AllYouZombies" by Creator/RobertAHeinlein. [[spoiler:[[OneDegreeOfSeparation There is only one character in the story]]. Who is ''[[MyOwnGrampa both]]'' [[MyOwnGrampa of his own parents]], being a {{Hermaphrodite}} who lived first as a woman, then lost his female parts due to complications from giving birth and switched to living as a man, then went back in time and had sex with his female self in an attempt to save himself from that jerk who knocked him up and then disappeared on him, then realized that the jerk was himself. Meanwhile, the bartender/time-travelling secret agent who helped him go back in time went ahead nine months to kidnap him as a baby, then went back further in time to drop him off at an orphanage. Because the bartender is ''also'' him, only older, and he wants to ensure that the StableTimeLoop that is his own life remains stable.]]
* Heinlein's ''Literature/TimeEnoughForLove'': Lazarus Long at first objects to screwing his own [[OppositeSexClone identical-twin female clones]], but relents when they assure him it's no more than "Narcissus loving himself."
* ''Literature/DowntimingTheNightSide'', by Jack Chalker. Not as squicky as it sounds: By the time the hero/heroine hooks up with him/herself they are essentially different people thanks to a GenderBender, several [[StableTimeLoop time loops]] and the side effects of the book's time travel {{Phlebotinum}}.
* F.M. Busby wrote a short story with a similar concept using {{Reincarnation}} instead of a GenderBender. The hero dies and finds himself reborn in the past as the girl who will eventually become his beloved wife. He/she then gets to re-experience their life together from her perspective, eventually giving birth to a daughter who turns out to be (surprise, surprise) him/herself yet again, reborn once more into the past.
* Fifteen-year-old Henry finds an outlet for his pubescent sexual urges this way (and, it's implied, repeatedly) in ''Literature/TheTimeTravelersWife''. For added fun, his father walks into the room and catches him (them?) ''in flagrante''. Henry rationalizes having gay sex with himself as a parallel to masturbation, and the obvious course of action that "anyone" would take in his situation (thankfully, his eponymous ''wife'' never needs to hear about it). Note that possibly they were only jerking each other off. And the father walks in on them post whatever-happened, although it was still totally obvious to him that it was something sexual.
* ''Parallelities'' by Alan Dean Foster not only has the main character bedding an alternate female version of himself while traveling through TheMultiverse, he eventually finds an alternate Earth populated entirely by doubles of himself.
* The ''Literature/{{Darkover}}'' novel ''Two to Conquer'' has the main character meet up with an exact physical duplicate of himself. The expected interaction occurs.
%%* ''Stork Naked'', by Creator/PiersAnthony.
* ''[[http://www.strangehorizons.com/2008/20080818/sexghosts-f.shtml Sex with Ghosts]]'', by Sarah Kanning.
* While the book doesn't get that far, in ''Literature/MajykByDesign'' by Creator/EstherFriesner, a cat (talking, magical) named Scandal gets split up into a number of copies by villains (who can control the copies). By the end of the book, he reabsorbs them. ''Except'' for the one representing his female side, who being just a kitten was useless to them and out of the fight. He's accelerating her maturation, for this trope's purpose, with her full encouragement. (They ''are'' the only two cats in this world...)
* "Nine Lives", an early Creator/UrsulaKLeGuin story, has a set of ten clones, five male and five female, who join some place where there were already two normal people working. When the clones have sex with each other, one of the non-clones says, "Oh, let them have their damned incest!" and the other says, "Incest or masturbation?" (The clone-sex wasn't a major plot point, just a part of showing how the clone-group couldn't relate properly to outsiders.)
* A similar case of clone incest appears in Creator/JohnVarley's ''[[Literature/GaeaTrilogy Titan]]'', where the lab-cloned Polo sisters privately engage in behavior that's still illegal in Alabama.
* Varley's stories have often had this, including ''The Phantom of Kansas''.
* Used romantically with several pairings amongst the {{Starfish Character}}s in ''Literature/ScorpionShards''. They are soul mates, so to speak, but it gets a little weird when one of them realizes he can't fall in love with someone who isn't part of the group.
* The main character in James Alan Gardner's ''[[Literature/TheLeagueOfPeoplesVerse Commitment Hour]]'' spends the last few chapters of the book [[spoiler:having "impure" thoughts about a female clone of himself]]. To make matters worse, [[spoiler:their minds are linked to share memories between them, so she "hears" every one of the thoughts. ''And likes them'']]. The end of the book [[spoiler:strongly implies the the character ends up romantically involved with his own clone, while a third, hermaphrodite clone has a whole 'nother squick going on]].
* In Creator/FrederikPohl's ''The Coming of the Quantum Cats'', similar characters from a mulititude of timelines mix & match during a cross-time war; when a slightly more advanced timeline decides to quarantine the others to avoid eddies in the space time continuum, a lot of editions get dumped on an uninhabited Earth, where multiple copies of a particularly unsavory mook decide to set up house together.
* In ''Literature/WithATangledSkein'', Niobe kisses ''two'' alternate timeline versions of herself. Clearly justified, as Niobe is essentially described repeatedly as the most beautiful woman of her generation.
* The short story "Blood Sisters" by Creator/JoeHaldeman involved the Mafia cloning a young heiress in order to substitute the clone and get the inheritance. The clone didn't want any part of the plan--she thought of the original as her mother and didn't want her murdered--and went to a private detective to ask for help hiding from the Mob. When she finally ''met'' the heiress, however, the mutual attraction was strong enough to overcome any qualms about [[ParentalIncest being intimate with her mother]]. The detective comments, "I did wonder what you would call what they were doing. Was it a weird kind of incest? Transcendental masturbation?" At the end of the story, it's mentioned that original and clone openly being lovers "started a fad among the wealthy, being the first new sexual diversion since the invention of the vibrator."
* A strange case in Creator/SergeyLukyanenko's ''Autumn Visits'', where Anna has a [[NoodleIncident "shower moment"]] with her not-quite-human duplicate Mary. It's not specified exactly what they do in the shower, but their mutual attraction is clear, although Anna's attraction is mostly due to religious fervor (she believes Mary to be {{God}}).
* Creator/IsaacAsimov wrote a parody of "Home on the Range" called "Home with my Clone" ("...with the Y chromosome turned to X.")
* In ''Literature/{{Redshirts}}'', the main characters get [[spoiler:the actor playing one of the stars of the television show they're characters on]] to help them when [[spoiler:the character he plays]] seduces him. [[spoiler:Or not, they actually just talked.]]
* In "A Clone at Last", a short story by Bill Pronzini and Barry N. Malzberg, a man who has little luck with women commissions a female clone of himself. He waits until the clone is eighteen years old before he tries to seduce her to avoid being arrested for statutory rape.
* In the book ''Literature/{{Goldfinger}}'', when he has captured Bond and expects him to talk (also to die), Bond steels himself, telling him "you can go [[NarrativeProfanityFilter ____]] yourself." Goldfinger good-naturedly replies "Even I am not capable of that, Mister Bond!"
* The protagonist in Creator/RobertLForward's ''Timemaster'' gets into a foursome with his wife, himself, and himself. Hey, it was ''her'' idea!
* In ''Literature/ASongOfIceAndFire'', Cersei Lannister is having sex with her twin brother, and it's heavily implied to be because this is the closest she can get to having sex with herself. To the point that when Jamie returns to King's Landing looking different (having shaved his head and grown a beard) she is less attracted to him because they now look different.
* ''[[Literature/{{MARZENA}} The MARZENA Series]]'' gives us Marian and Geni. Geni is actually a holographic AI clone of Marian created via mind merging with a BlankSlate. To get access to the master computer, Marian and Geni need to combine their brain activities together by fully merging with each other, resulting in supernova ghostgasms.
* ''Literature/TheRook'' technically features this, as [[spoiler:the character of Gestalt is one mind in four bodies, including a female twin]]. However, in this case it serves a 'practical' purpose; [[spoiler: by conceiving a new body with their exact genetic material, Gestalt created the potential for it to become essentially immortal so long as it conceived new bodies]].
* In the Venom's Taste ForgottenRealms trilogy, Zelia (a female yuan-ti psion) likes to use [[MesACrowd Mind]] [[SplitPersonalityTakeover Seed]] on handsome males. This power effectively [[CloneByConversion puts a weaker clone of her mind into the victim, eventually replacing it]]. Then she has sex with them.

[[folder:Live-Action TV]]
* In the first season finale of ''Series/TwoBrokeGirls'', Max looks at herself in the mirror and says "Damm girl! You look good! What are you doing tonight? Can I get your number?"
* ''Series/ThirtyRock'':
** The incredibly self-absorbed Jenna starts dating a celebrity female impersonator of herself. It's about as close to this as a heterosexual woman can get without the benefits of advanced technology.
** In the episode where Tracy buys a "Japanese Sex Doll" of himself, Jack asks him why he would make such a purchase "other than the natural inclination to make to love to yourself".
** During the 100th episode, while everyone is hallucinating, Jack is visited by three versions of himself from his past, an alternate present, and his current future. After he resolves his existential crisis, the three of them stand around and decide that the only rational option is to go have sex with each other.
* G-Rated ''Series/ANTFarm''. Lexi has an {{Erotic Dream}} about kissing herself at the end of "Id[=ANT=]ity Crisis".
* ''Series/BuffyTheVampireSlayer'':
** Willow's LesbianVampire EvilTwin acted interested in getting physical with her human counterpart.
--->'''Vamp Willow:''' I kinda ''like'' the idea of the two of us. We could be quite a team, if you came around to ''my'' way of thinking.\\
'''Willow:''' Would that mean we have to... snuggle?\\
(''Evil Willow brushes Willow's hair away from her neck'')\\
'''Vamp Willow:''' What do you say? (''{{lecherous licking}}'') Wanna be bad?\\
'''Willow:''' This just [[SickAndWrong can't get more disturbing!]]
** This was also brought up in the episode where Xander was split into two Xanders, though the comment was about a threesome with them and Anya. The other Xander in that scene was being played by Nicolas Brendan's identical twin brother, so there could have been some {{Twincest}} there as well.
** In the first ''Spike'' issue of the Season 9 comics:
--->'''Elizabeth:''' I have ''never'' seen his majesty like this before.\\
'''Sebastian:''' He has told us to sod off before, Elizabeth. Just last week, he told Scotty and me to engage in an activity so anatomically impossible that--
* ''Series/TheColbertReport'' has two Santa Clauses come on stage and make out with each other.
* ''Series/DoctorWho'':
** [[Recap/DoctorWhoS29E11Utopia "Utopia"]]: While at the end of the universe, the immortal Captain Jack mentions that he could go and meet himself. The Doctor quips, "He's the only man you're ever gonna be happy with."
** In [[Recap/DoctorWhoS30E13JourneysEnd "Journey's End"]], [[spoiler:three versions of the same Doctor are formed: the Doctor proper, the Clone Doctor and the [=DoctorDonna=]].]] [[AnythingThatMoves Captain Jack]], when finding out that "there are three of you now?", says "I can't tell you what I'm thinking right now."
** [[Recap/DoctorWho2011RNDSSpaceAndTime "Space" and "Time"]] have a timeslipped Amy Pond. If they don't act carefully the slip will stick and they will be stuck with two Amys, and when asked what he would do then Rory [[TwinThreesomeFantasy "has a few ideas"]]. Later on, Amy and Amy start flirting with each other.
--->'''Amy 1:''' [[DoIReallySoundLikeThat Do I really look like that?]]\\
'''Amy 2:''' Yeah. Yeah, you do.\\
'''Amy 1:''' Mmm . . . I'd [[ItMakesSenseInContext give you]] a [[UnusualEuphemism driving licence]].\\
'''Amy 2:''' I'll bet you would.\\
'''The Doctor:''' Oh, this is how it all ends. Pond, flirting with herself. True love at last. (''remembers that Amy's husband is also present'') Oh, sorry Rory.\\
'''Rory:''' (''nearly catatonic'') [[GirlOnGirlIsHot ...absolutely no problem]] [[TwinThreesomeFantasy at all...]]
** [[Recap/DoctorWhoS32E7AGoodManGoesToWar "A Good Man Goes to War"]]: River Song, while talking to Rory, implies that she once had a three-way with two different Doctors via abuse of time travel.[[note]]Given the way that the Blinovitch Limitation Effect appears to affect Time Lords, this may imply that it was with two different incarnations of the Doctor as well.[[/note]]
** Likewise the mini-episode [[Recap/DoctorWhoS33ShortClaraAndTheTardis "Clara and the TARDIS"]] has Clara complaining that the [[ClingyJealousGirl TARDIS]] has just [[EldritchLocation vanished her bedroom]]. Due to TimeyWimeyBall effects, the console room ends up full of Claras all shouting at the TARDIS to tell them where the bedroom is. Two of the Claras say, "You think you've got problems." (''look at each other flirtatiously'') [[FinishDialogueInUnison "We've got to]] [[LesYay share a bed."]]
** In "Listen", Clara checks out herself from slightly earlier in her timeline, striding away from her in a tight skirt.
-->'''Clara:''' Is that what I look like from the back?
-->'''The Doctor:''' It's fine.
-->'''Clara:''' I was thinking it was ''good.''
** The short story collection ''Short Trips: A Christmas Treasury'' has one story with a more innocent version. The [[CuddleBug Eighth Doctor]] has brought [[UnderTheMistletoe mistletoe]] to a Christmas party with his former selves, whom he attempts to kiss, but most of them are rather disinclined to acquiesce. (He manages to get a snog from Five and Three, at least.)
** [[MissingEpisode Rejected book]] ''Campaign'' involves Ian Chesterton being in love with a parallel iteration of himself, Cliff, when they accidentally experience the lives of two entirely unrelated and very obscure ''Doctor Who'' characters. They end up living as a married couple in a time period where their love is forbidden, and continue shaggin' after they escape from their WorldLimitedToThePlot. Surprisingly, [[MindScrew this is far from the weirdest sexual relationship in the book]].
** Averted in [[Recap/DoctorWhoS34E5TimeHeist "Time Heist"]], in which Saibra, a shapeshifting character who uncontrollably assumes the form of anybody she has skin contact with, laments that she CantHaveSexEver because everybody she's ever been attracted to has found having sex with a copy of themselves too disturbing.
** One script draft of "The End Of Time" had the following scene which, tragically, didn't make it to the screen:
-->'''The Master:''' Yeah, as much as I like looking at myself, I think you can get out of that dress.\\
'''The Master:''' Is that an invitation?\\
'''The Master:''' Now that would be different. And brilliant. But later!\\
'''The Master:''' I'm a psychological minefield.
** Creator/StevenMoffat likes to write bits of CrackFic in his Magazine/DoctorWhoMagazine column, and once wrote a completely mental Delgado Master / Gomez Master drabble.
** In [[Recap/DoctorWhoS36E11WorldEnoughAndTime "World Enough and Time"]] and [[Recap/DoctorWhoS36E12TheDoctorFalls "The Doctor Falls"]], [[spoiler:the John Simm Master openly hits on Missy at every turn, and it's implied he got sexually aroused when she aggressively shoves him up against a pillar. Missy however has a NoJustNoReaction.]]
* ''Series/{{Dollhouse}}'': When he is forced to accompany Adelle to the Washington DC Dollhouse, Topher imprints Victor, a blank active, with his own personality in order to mind the shop in LA. This leads to the following exchange over the phone:
-->'''Topher:''' She's got me locked out on this end.\\
'''Victor!Topher:''' Who's your back door man?\\
'''Topher:''' We'll pretend I didn't say that.\\
'''Victor!Topher:''' Yeah.
* ''Series/GameOfThrones'': Cersei's incest with Jaime is, according to the cast and crew and in consonance with her thoughts in the books, her attempt to get as close as she can to making this a reality. She sees Jaime as what she was actually meant to be and denied the privilege of being by being born a woman. Thus by having sexual intercourse with Jaime, she is, in her own mind, screwing herself. As such, to Cersei it's not incest but rather ''incredibly'' metaphorical masturbation.
* In one episode ''Series/HannahMontana'', after seeing a picture of herself as Hannah Montana photoshopped to make her look like a guy, Miley comments that she would totally date herself.
* ''Series/HemlockGrove'': After Olivia downloads her personality into a male body, the first thing she wants to try out is to have sex with herself. Even the amoral Dr. Pryce is disgusted by her blatant narcissism.
* One of the ways the illusion-casting Candice from ''Series/{{Heroes}}'' tries seducing Sylar is by appearing to him ''as Sylar''. ("Or something more familiar... if that's what you're into.")
* Robin from ''Series/HowIMetYourMother'' honors this trope as well. Once she gets back from Argentina, she undergoes an identity crisis while talking a lot, in her dreams, to her vacation double. At the end of one dream, her dream self seemed to be making a pass at her. When Robin is finally herself again, the implicitness is subverted as she mentions that "vacation Robin" popped up in her dreams again and they went all the way.
-->'''Robin:''' That chick knows what I like.
* Though not shown onscreen, [[Creator/DavidTennant Kilgrave]] from ''Series/JessicaJones'' leaves it up to the viewer's imagination when he explains the following scenario as a reason why he has to be careful about the phrases he gives when using his mind control powers: "I once told a man to go screw himself. Can you imagine?"
* A multi-part sketch in an episode of ''Series/TheKidsInTheHall'' has the troupe discovering Scott Thompson has built a robot substitute. Unfortunately the robot has no concept of societal restrictions, meaning it's hitting on everyone and is about to force itself it on Mark [=McKinney=]. When the real Scott arrives to defeat it the robot is distracted by the sexiness of its creator, giving Scott enough time to find the right remote to turn it off. TheStinger reveals Scott has committed this trope.
* In the ''Series/LostGirl'' episode "Scream a Little Dream", Bo gets a dream including a version of... herself from the future after all her {{Love Interest}}s have died, who [[HornyDevils insists upon stealing a kiss (and her powers) from her]].
* A skit on ''Series/TheManShow'' had Adam Corolla and a clone of himself, eventually coming to the conclusion "After all, it's only me, right?"
* In ''Series/MarriedWithChildren'', the narcissistic Jefferson sometimes expresses a desire to make love to himself. In one episode, the Bundys listen to Jefferson and Marcy having sex. Marcy moans and screams his name, and Jefferson moans and screams his own name.
* ''Series/{{Misfits}}'':
** At the beginning of the third series premiere, new character Rudy mentions that he would definitely have sex with himself if he could. Bravado maybe, but thanks to his power he actually ''can''.
** [[spoiler:While it may not involve actual sex, it probably still qualifies as selfcest--after Curtis gains the power to [[GenderBender swap genders]] he ends up getting himself pregnant by [[ADateWithRosiePalms "cleaning up"]] with the same tissue first as a man, then as a woman.]]
* ''Series/MysteryScienceTheater3000'' references this trope a couple of times, once when talking about a TimeTravel movie (''Time Chasers''), and once where a character is in a computer simulation with a copy of himself (''Overdrawn at the Memory Bank'').
* An episode of ''Series/NipTuck'' features a wealthy older gay man who hires the plastic surgeon protagonists to reconstruct the face of his young boyfriend to resemble a younger version of himself.
* In ''Series/TheOuterLimits1995'', episode "Mind Over Matter", a scientist invents a virtual reality device that lets you interface directly with people's minds. The virtual worlds can be populated with people from the users' memories. One character points out that a person created from someone's memories is technically part of them, and asks if having sex with one would count as selfcest, even if the simulated person was the opposite gender. The scientist gets annoyed and brushes the question off.
* ''Series/{{Perversions of Science}}'' used this concept. A man decides that no woman is good enough for him, so he decides to create "the perfect woman" by having a sex change and then going back in time to have sex with himself.
* Rob Brydon's onscreen kiss with Ben Miller on ''Series/{{QI}}'' after an episode's worth of jokes that they were identical.
-->'''Ben:''' So that's what it's like!\\
'''Rob:''' Now I know why my wife married me!
* In the ''Series/QueerAsFolk'' second season finale, Brian fucks the actor who played a superhero based ''heavily'' on himself. This is the catalyst for Justin leaving him.
-->'''Michael:''' You didn't have to walk out on him like that in front of everyone, you know.\\
'''Justin:''' I would've told him to go fuck himself, but he was already doing that, in the back room with Rage.
* ''Series/RedDwarf'':
** In "Parallel Universe", the crew goes to a parallel ''Red Dwarf'' where humans are all of opposite genders, and Lister gets drunk and sleeps with his female self, to the disgust of both versions of Rimmer.
--->'''Arlene Rimmer:''' How could you possibly contemplate making love to yourself?\\
'''Arnold Rimmer:''' Well, [[ADateWithRosiePalms why break the habit of a lifetime]]?
** Of course, Arlene Rimmer [[HypocriticalHumor was also trying to come on to Arnold Rimmer]], using (or planning on using) [[CallBack the same crappy pick-up lines and talent for hypnosis he mentioned at the beginning of the episode]]... she was also planning on showing him some [[GirlOnGirlIsHot Guy on Guy porn]] [[YaoiFangirl she owned]] in the hopes it would "loosen him up".
** The parallel universe has male and female roles completely switched, so Deb Lister gets Dave Lister pregnant. This is revealed immediately before the end of the episode, and what happens to the fetus is dealt with in some fast scrolling text at the start of the following season...
** In this same storyline, the Cat is very excited to meet his female opposite and is clearly planning to have sex with her. "If you hear me screaming, do not, I repeat, DO NOT come to the rescue!" Of course, his opposite turns out to be [[spoiler:a male dog]].
** Ironically, in "Rimmerworld", he decides to make an OppositeSexClone of himself... somehow. And then have sex with the clone, despite some misgivings:
--->'''Rimmer:''' This of course created the most enormous moral dilemma. Technically, she would be my sister, and therefore unable to take me as her lover. After much soul searching, I reluctantly decided, "What the hell", I just wouldn't tell her.
** [[spoiler:He fails, of course.]] However, the resulting [[spoiler:male clone]] does not, and goes on to eventually [[spoiler:create an entire population of "Rimmers", both male and female.]] Even more disturbing is the fact that [[spoiler:their cultural rules require execution of anyone who does not meet the exact physical and moral attributes of the original Rimmer. Although for the women, this means facial features only...]] which really isn't any better.
** In the episode "Camille", they met a Gelf who appeared to each character as their "perfect companion", which everyone assumed to be their perfect ''female'' companions. Predictably, Lister saw Kochanski (or rather, Kochanski if she was a bit more like him, including Scouse accent); slightly less predictably, Rimmer saw a fairly plain, underachieving hologram; and Kryten saw a robot which looked very similar to him (because they're from the same series, series 4000), but had a distinctive personality and looked slightly more feminine. The Cat, after much excitement, finally sees himself.
--->'''Cat:''' I'm the object of my own desire?!\\
'''Gelf Cat:''' Can you think of anyone more deserving?\\
'''Cat:''' Well, when you put it like that, I guess not! Damn my vanity!
* The three-part ParodyCommercial of Lincoln Financial on the season 37 episode of ''Series/SaturdayNightLive'':
** The first time (with Jason Sudeikis as his younger self and his older self) played it straight and briefly conversed it (Sudeikis's older self tells his younger self that "It's not gay" because "I'm you" and asks him if he ever wondered what it would be like to have sex with yourself, which convinces his younger self to go through with it).
** The second time (this time with Bill Hader as his younger self and a disgusting, overweight version of himself in about two years) plays this for BlackComedy (with some hints of CrossingTheLineTwice) when, after his overweight, disgusting future self tells him that he'll end up fat from too many steak dinners, broke from blowing all of his money, and on a plane to Hawaii where he'll "disappear" [[labelnote:*]]i.e., commit suicide by putting a gun in his mouth and blowing his brains out[[/labelnote]], the overweight future self tries to rape his younger self (with his younger self shouting, "No, no, no, no!" and trying to fight him off).
** The third one had Creator/BenStiller mistaking a woman (Creator/AbbyElliott) sitting next to him for his future, transgender self--until his actual, future transgender self tells the woman that the man was talking to her.
* Subverted on ''Series/{{Scrubs}}'': J.D. thinks that his girlfriend, Dani, moaned her own name during sex, but it was actually the guy she was seeing at the time, whose name is Danny.
* Tony has sex with Beth in his series 2 episode of ''Series/{{Skins}}''. Possibly. Beth is either a figment of his imagination, an aspect of his personality (his long-lost ''anima''), his sister, himself, a completely random person, or--most likely--[[MindScrew all of the above]].
* In ''Series/{{Sliders}}'', Quinn once discusses his adventures on a talk show, and mentions having met a female version of himself. He is immediately asked, "Did you have sex with her?" (We never really found out if he did, though they did kiss. She was AxCrazy, anyway.)
* ''Series/StargateSG1'': Given how much {{puppet|eerParasite}}master Ba'al was hitting on [[CrystalDragonJesus Adria]], what he ''might'' have had in plan after one of his clones possessed her may have fit the trope. However, he never got to carry out his plans, so we may never know... which is probably best.
* ''Series/StarTrekDeepSpaceNine'':
** Kira's EvilCounterpart in the MirrorUniverse had the hots for her. (Though granted Kira's EvilCounterpart has the hots for ''[[AnythingThatMoves everyone]]''.) The writers of the show at the time of that episode have revealed that this was meant to show how extremely [[{{Narcissist}} self-absorbed]] Mirror Kira was, but later writers interpreted it differently and they have shown her with [[DepravedBisexual both male and female partners]] when revisiting the MirrorUniverse.
** "Facets" reveals that Curzon fell in love with Jadzia when he was mentoring her; they end up joined to the same symbiote, becoming a retroactive version of this trope by way of TheNthDoctor.
* On ''Franchise/StarTrek'' [[Series/StarTrekTheOriginalSeries TOS]], we have the HoYay between Kirk and Id!Kirk from "The Enemy Within".
* ''Series/{{The Suite Life On Deck}}'': London is entirely made for this trope. There was even one episode where a dating questionaire set her up with herself.
* Though nothing comes of it [[spoiler:save a broken neck]], ''Series/TerminatorTheSarahConnorChronicles'' has some terribly disturbing [[StarBoarding one-sided]] LesYay from Cameron toward Allison.
* On ''Series/That70sShow'', an episode revolves around [[HomoeroticDream Fez having a dream where Kelso gives him a sponge bath.]] At the end of the episode, Kelso has the same dream (himself giving himself a spongebath). And likes it.
* Well, Alex from ''Series/WizardsOfWaverlyPlace'' doesn't meet herself and make beautiful music, but she still falls in love with herself when she drinks both halves of a love potion. The bad part is that her head gets big whenever she compliments herself... ''[[LiteralMetaphor literally big]]''.
* ''Series/{{Danger 5}}''. Hitler tries to snog himself when his personality is put inside a female body. After a NoJustNoReaction from her, Hitler mutters, "[[AllMenArePerverts Every man would have tried]]."

* Music/MindlessSelfIndulgence expresses a wish for this in "Make Me Cum".
* "Hot Sauce and Ice Cream", by Music/TomSmith, features this briefly near the end, before it turns into a TwinThreesomeFantasy.
* "Destiny Street", from the LP of the same name by Richard Hell and the Voidoids. A time-travel fantasy, IIRC. And Richard Hell is smoking hot.
-->''Yes, I seduced myself\\
I took me home\\
I whispered that only I could make\\
The younger guy feel less alone.''
* Music/TVOnTheRadio. "I Was A Lover" has a section about how the narrator seduces his clone when no one's around. It's probably metaphorical, but still counts.
* Music/LadyGaga
** "So Happy I Could Die."
** Taken to a much more ridiculous extreme in the video for "You And I", where her lover's role in the video was played by herself in her [[OppositeSexClone drag alter-ego]], [[{{Bishonen}} Jo Calderone]]. She also performed the song live as him at the MTV awards.
* Music/TomWaits's "Better Off Without a Wife"
-->I've always kind of been partial to calling myself up on the phone and asking myself out. You know... ''(whoops from the audience)'' Oh yeah, you call yourself up too, huh? Yeah... Well, one thing about it, you're always around! Yeah, I know. Yeah, you ask yourself out, you know. Some class joint somewhere. The Burrito King or something. You know... Well, I ain't cheap, you know. (...) Well, usually about 2.30 in the morning you've ended up taking advantage of yourself and... there ain't no way around that, you know. Yeah, making the scene with a magazine, there ain't no way around... I'll confess, you know, I'm no different, you know. I'm not weird about it or anything. I don't tie myself up first.
* Music/{{Rammstein}}'s "Zwitter" is sung from the perspective of a hermaphrodite who is in love with him/herself. The lyrics are explicit about this trope.
-->''"Ich bin alleine doch nicht allein, ich kann mit mir zusammen sein"'' (''I am alone but not alone, I can be together with myself'')
-->''"So bin ich dann auch nicht verzagt, wenn einer zu mir "Fick dich" sagt"'' ("So I'm not sad, even when someone says "Fuck yourself" to me.")
* Schaffer the Dark Lord's "Attack of the Clone Fucker".
* The video for "Sober" by Music/{{Pink}} features Pink, in naughty lingerie, making out with... another Pink in other naughty lingerie. Take a look [[http://www.youtube.com/watch?v=nJ3ZM8FDBlg here]]. Starts about 2:20 and gets intercut here and there nearly to the end.
* The music video for "The World Is Not Enough" by Music/{{Garbage}} has the robot double of the lead singer killing the real singer (Shirley Manson) by kissing her.
* The video for [[http://www.youtube.com/watch?v=EjAoBKagWQA "All is Full of Love"]] takes place in a factory producing Music/{{Bjork}} [[{{fembot}} gynoids]]. Two of them start kissing and fondling toward the end of the video.
* A scene in one version of Music/JanetJackson's "Together Again" video has Janet Jackson leaning her face and hand on the breast of another Janet Jackson who is wearing a [[NippleAndDimed strategically pixelated]] transparent top.
* Cat Rapes Dog's song "Adore Myself" is about either this or regular old narcissism.
* Dave Grohl of Music/FooFighters in the video for "Learn to Fly". Twice. A pigtailed girl played by Grohl has a crush on Grohl AsHimself, and the CampGay flight attendant flirts rather suggestively with the pilot, both also played by Grohl.
* Music/NickiMinaj's guest verse in Music/KanyeWest's "Monster" has her doing a SplitPersonality act with her rap, switching between a baby-girl voice and a strident, dancehall-styled 'monster' voice. The video represents this as Monster!Nikki ([[EvilCostumeSwitch in black lace and fangs]]) giving a lapdance to Innocent!Nicki.
* [[http://theneedledrop.com/wp-content/uploads/2011/06/Sebastian-Total-ICanGiveYouHouse.Com_.jpg The album cover]] of ''Total'' by Sebastian.
* The [[https://youtu.be/608BLWdT_OI video]] for Torres' track "Three Futures" features three separate characters all played by Torres herself, and ends with them having sex.

[[folder:Myths & Religion]]
* In the Literature/BookOfGenesis, this trope goes right back to the literal interpretation Adam and Eve, as it's written that Eve came from Adam's rib.[[note]]Or, respectively, if you take it either literally or the wrong (?) translation. There are some who interpret the Hebrew word as "side" or "aspect" and say, that Adam was a hermaphrodite in some way and the God took the female side/aspect and made it into a separate being.[[/note]] There are also the interpretations that suggest she was made from a different bone entirely, one present in many mammals but not in humans.[[note]]Specifically the ''baculum'', which is a bone in the penis to help with copulation. Humans do not have them, and function entirely hydraulically.[[/note]]
* Narcissus in Myth/GreekMythology fell in love with his own reflection. It also helps that he's the namesake for {{narcissis|t}}m.

* ''[[http://www.prometheusradiotheatre.com/arbiters.php The Arbiter Chronicles: Divergence]]''

[[folder:Tabletop Games]]
* The player's handbook to ''TabletopGame/{{Aberrant}}'' (a White Wolf RPG centered around people developing superpowers as a world-wide phenomenon) contain a chapter with various superhero teams and similar groups across the world (some of which are painfully ethnic). One is the Queer Nova Alliance, an informal group of Novas (superpeople) with "alternate lifestyles". One member is Tommy Orgy, whose selection of powers includes self-cloning. Or, as another nova observes, "Gorgeous, gay, and able to duplicate himself; its a wonder Tommy Orgy ever leaves his house." When Tommy tells another nova to "Go fuck yourself", the other retorts, "I thought that was more your forte, Thomas." A listener adds, "Well, according to every other fanfic I read on the [=OpNet=], anyways..."
* Doable in ''TabletopGame/GeniusTheTransgression'', although most of the available methods are a) major KarmaMeter transgressions, b) really stupid, or c) both.
* There are a number of ways to go about this in ''TabletopGame/MageTheAwakening''. Shapeshifting lets one person take the form of another, but it's also possible for a mage to divide into two [[MesACrowd or more]] bodies. The more esoterically inclined can journey into their own minds or cause aspects of their personalities to manifest physically: there's a mention of a mage who incarnated their own lust. [[UpToEleven Archmasters]] can create avatars; meet past, future, or alternate-timeline versions of themselves; and do it all in worlds generated from their souls, where they are aware of everything happening within. PowerPerversionPotential indeed.
* ''TabletopGame/TwilightSparklesSecretShipficFolder'' has three versions of each Mane Cast member (four of Twilight), two versions of every princess, and two versions of Shining Armor. There are ''goals'' for this.

[[folder:Video Games]]
* ''Franchise/MetalGear'': There's the marketing campaign for ''VideoGame/MetalGearSolidPeaceWalker'', which [[{{Fanservice}} furiously attempted to encourage this as much as possible]]. The first trailer alone depicted four Big Bosses, and at the end they got in a pink box (labelled "LOVE PACK") which jiggled suggestively, alerting a nearby guard. The second trailer involves soldierly HoYay {{C|leanPrettyReliable}}PR and masculine hand-holding and dialogue about always sticking together, between two Big Bosses. Whether this becomes part of the game or not remains to be seen, but Creator/HideoKojima is at least having fun with it.\\\
It's now been revealed that a) the four demo-ready character builds are all different versions of Big Boss, and b) the Love Box is indeed a two-person cardboard box and that if two Big Bosses stay still in it for too long, it will start to jiggle around. Not surprising, as [[EvenTheGuysWantHim even the guys want Big Boss]], and that includes Big Boss. The official website gives an innuendo-filled description of the Love Pack, saying 'in the spirit of camaraderie, some may find it comfortable!'. And also reveals that the characters giggle when taking items from each other, because it tickles. Big Boss is officially the gayest thing in an already incredibly gay series, ''and for himself''. [[MindScrew We Think.]]
%%** In ''VideoGame/MetalGearSolid3'', dress Snake up to look like Raikov, stand in front of Raikov, and ''just wait''.
* ''VideoGame/KidIcarusUprising'': In Chapter 21, in the middle of an asteroidal [[MultiMookMelee endless arena]], Pit and Dark Pit shout out a battle cry/victory speech, after which Viridi responds: "Nice speech guys. Did you stay up all night writing it? [[ParentalBonus Or Maybe it's your super-secret twin connection talking]]?"
* ''VideoGame/{{Darkstalkers}}'': Morrigan and Lilith are technically two fragments of the same soul. The game art depicts them embracing, naked. What did you expect from HornyDevils? Also, it's ''not'' just the game art. In ''Darkstalkers/Red Earth: Maleficarum'' is a 2-page picture with Lilith once again embracing Morrigan while looking back at the reader with a knowing grin. (But they're wearing their [[{{Stripperific}} scanty costumes]] this time.)
* ''Franchise/FinalFantasy'':
** In ''VideoGame/FinalFantasyVII'', Cloud can visit a brothel. In one of the rooms he has one of his frequent psychotic episodes and hallucinates another him, crouched in pain by the hot tub. If you speak to the other Cloud, he berates the real Cloud for being in a place like this, and then leans in to kiss Cloud. The real Cloud passes out as their lips touch.
** And the Genesis Copies in ''VideoGame/CrisisCore''. [[spoiler:And if Angeal wasn't dead by the time, he and Lazard would have been candidates.]]
* Mentioned in the [[Radio/GTARadio radio and newspaper sources]] in ''[[VideoGame/GrandTheftAutoIV Grand Theft Auto 4]]''. A scientist has cloned several copies of himself for sexual purposes. And one of his copies is [[NoYay underage]].
* When a Spy dominates an enemy Spy in ''VideoGame/TeamFortress2'', he will frequently say lines that border on HoYay... but it is important to remember that they are essentially [[PaletteSwap the same person.]]
* Breeding with Ditto in the ''Franchise/{{Pokemon}}'' games ''may'' invoke this trope. (We don't know for sure because, if anyone's actually seen the HotSkittyOnWailordAction in person, they aren't admitting it to the protagonists.)
* In ''VideoGame/DigitalDevilSaga'' it is almost casually mentioned how Sera was [[spoiler:conceived of Jenna Angel's egg AND sperm. This is supposedly possible because she is a {{Hermaphrodite}}.]]
* Adding onto the Atlus, ''[[VideoGame/RaidouKuzunohaVsTheSoullessArmy Raidou's]] [[VideoGame/RaidouKuzunohaVsKingAbaddon series]]'' have a dimensional rift, allowing Raidou to meet [[spoiler:another version of himself: Raido Kuzunoha XIV--whose differences include scars on his face and speaking like a normal character]]. While they don't stay together all that long (because their meetings always end in [[spoiler:one sending the other back to his original dimension]]) fanon sometimes persists in shipping the two, mainly played for drama.
* Played with in ''VideoGame/KingdomHearts358DaysOver2''. Roxas and Xion become quite close, and Xigbar even [[ShipperOnDeck gives Roxas dating advice to impress Xion.]] This quickly turns disturbing when it is revealed [[spoiler:Xion is a Sora clone. Oh, and she's been sucking the life out of Roxas the whole time, and she doesn't even know it.]] It gets even more ridiculous when you learn that Xigbar at some point sees Xion as [[spoiler:Ventus of ''Birth by Sleep''--and while not the same person as Roxas the two do look ''suspiciously alike'']].
* In ''[[VideoGame/SamAndMaxFreelancePolice Sam and Max Season 2 Episode 1]]'', ghosts of Sam and Max [[Literature/AChristmasCarol travel to the Christmas of the Future]] to save their future selves from dying a horrible death on a river of lava. If Sam suggests haunting their future selves, Max says that they should, only if ''he'' haunts Future Sam and Sam haunts Future Max--"otherwise, it'd just be gross". However, he also hits on his future self--"Hey, sexy! I'll be back to pick you up later!"
* In ''VideoGame/DissidiaFinalFantasy'', [[VideoGame/FinalFantasyVI Kefka's]] MirrorMatch battle taunt resembles this trope (that or DistractedByMyOwnSexy):
-->'''Kefka:''' Who's ''that'' handsome devil?
* Modifying the visuals of certain games, such as ''Franchise/ResidentEvil'', can allow this sort of thing to occur. For example, [[http://www.youtube.com/watch?v=_9WwEgCmQgI this video]] replacing both TheVamp Excella trying to flirt with BigBad Wesker in ''[[VideoGame/ResidentEvil5 5]]'' with Chris (although despite the change in appearance the mechanics for the original characters still operate, such as Excella's JigglePhysics applying to Chris's chest gear).
* In the "Old World Blues" DLC of ''VideoGame/FalloutNewVegas'', [[ItMakesSenseInContext you meet your own brain]]. With the right perk, you can flirt with it ("You're my brain and I'm your body! It's meant to be, baby!"). It is completely disgusted by the suggestion.
* Thanks to the Alchemy potions in ''VideoGame/TheSims3'' ''Supernatural'' expansion, your sim can brew up a clone potion, use it to clone themself, romance said clone and then, well, get it on with them.
** And in the ''Get to Work'' expansion of ''VideoGame/TheSims4'', your Sims can enter the Scientist career, which unlocks several new inventions for your own home, including a cloning machine, which can clone both regular household items and other Sims.
* In the Good Ending[=/=]True Ending Route of ''VideoGame/HyperdimensionNeptuniaV'', Neptune finally gets to see her alternate self, Purple Heart [[spoiler: via CloningBlues (long story)]], and thinks that she's a cool, beautiful, and stylish woman. Sparkly eyes included.
* In ''VideoGame/TheBlackHeart'' Animus is a character who constantly changes gender during battle. If a MirrorMatch between two of them starts, the intro to the fight has them rather suggestively impaled while each sports a different gender.
* Highly implied with [[spoiler:The Luteces]] in ''VideoGame/BioshockInfinite'', who are [[spoiler:not siblings]] but rather [[AlternateSelf alternate]], [[OppositeSexClone opposite-sexed]] versions of the same person. The DLC ''Burial at Sea'' has a voxophone which suggests they're [[spoiler:considering ''having children'' together.]]
* Elphelt's [[FinishingMove Instant Kill]] in ''VideoGame/GuiltyGear Xrd'' involves her shooting her opponent with the rifle round equivalent of Cupid's arrow. This even works in a mirror match, with the Elphelt on the recieving end lampshading it.
--> '''defeated!Elphelt''': [[AnythingThatMoves I-I'll just take]] ''[[AnythingThatMoves anyone]]!?''
--> '''defeated!Elphelt''': If this works I'm going to cry forever!
* A cheat that was later deleted in ''VideoGame/SpiderManTheMovie'' allowed players to play as Mary Jane in the red dress from the Green Goblin's attack at the festival. The reason it was deleted was because the ending saw Spidey and MJ kissing--and if one used the red-dressed MJ, it resulted in this trope.
* In ''VideoGame/TheElderScrollsIIIMorrowind'', the [[ReallySevenHundredYearsOld 4000 year old]] BadassGrandpa sorcerer Divayth Fyr has created four [[OppositeSexClone Opposite Sex Clones]] who he variously refers to as either his "wives" or "[[IncestIsRelative daughters]]".

[[folder:Visual Novels]]
* The eroge ''X-Change'' toyed with the idea, having one of the girls apparently resemble Takuya's female form, but with a different hair color.
* ''VisualNovel/KichikuMegane'':
** This BLGame features uke salesman, Saeki Katsuya, who turns into a [[BespectacledBastardBoyfriend super sadistic seme]] when he puts on a pair of glasses given to him by a mysterious stranger. Several of the game's bonus scenes feature his glasses-wearing seme self doing very naughty things to the normal version.
** Played to the hilt in the sequel ''Kichiku Megane R'' where two of the bonus scenes revolve around [[spoiler:the two Katsuya's ''getting married.'']] {{Lampshade|Hanging}}d when glasses-wearing Katsuya points out that this is only possible because the sequel is also a fandisc.
* Teased in the paid version of ''VisualNovel/HatofulBoyfriend''. During the maid cafe scene, Ryouta holds up a mirror so the other birds can check their outfits. [[{{Cloudcuckoolander}} Oko San]] fails to realize the bird in the mirror is his own reflection, and tries to court it.
* During Ren's route of ''VisualNovel/DramaticalMurder'' you find out that [[spoiler: Ren is actually one of Aoba's two split personalities that was created to keep Aoba and his ''other'' destructive personality in check]]. Aoba and Ren have sex in Aoba's head, and then Ren's consciousness is [[{{Twincest}} implanted into the body of Aoba's twin brother]]. This doesn't stop them from continuing their relationship.
* In ''VisualNovel/FateHollowAtaraxia'', in the hanafuda game segment, Gilgamesh can interact with his child self. Gilgamesh hits on him.
-->'''Caren:''' I wouldn't have expected any less of you, King of Heroes. As long as it's blonde and has the body of a child, anything's fine right. But, that's a boy you know?\\
'''Gilgamesh:''' Mrph. Fool, don't underestimate me peon! As long as it's cute, it's A-O-K. The true hero is not concerned with the likes of male and female!

[[folder:Web Animation]]
* In episode 10 of ''WebAnimation/RetardedAnimalBabies'', the protagonists travel through the internet, find their creator's Newgrounds profile, and end up entering the beginning of the same episode. Effectively, they have traveled a few minutes into the past and are able to communicate with their past selves. The two Puppies immediately decide to have sex.

[[folder:Web Comics]]
* ''Webcomic/{{xkcd}}'' has [[http://xkcd.com/105/ touched upon this]] enough for the author to bring up the possibility that it's now "an official xkcd theme". And [[http://xkcd.com/267/ Here too...]]
* Well, it doesn't involve time travel but Black Mage of ''Webcomic/EightBitTheater'' has an EnemyWithout moment, but ends up killing the embodiment of his sins (himself) and re-absorbing all of his evil. Then he decides he needs to do something that makes self-love into an atrocity. Thief then [[RuleOfFunny somehow]] gets pictures and blackmails him.
* ''Webcomic/{{Homestuck}}'':
** Karkat has wondered whether he could be his own [[FoeYay kismesis]], although in practice that doesn't really work, even considering troll biology. In fact, this seems to be something of a recurring theme with him--when he sees [[spoiler:Jade arguing with her Dreamsprite]], he fantasizes about them making out and accidentally mistypes "make myself out to be" as [[FreudianSlip "make out with myself to be"]] in the connecting log with her.
** [[http://mspaintadventures.com/?s=6&p=005338 This update]] reveals that one of [[CatGirl Nepeta's]] [[ShipperOnDeck many, many ships]] is Jade auspisticing between past Karkat and future Karkat. Definitely a recurring theme. [[note]] Although because of how incredibly weird Troll Reproduction is, it isn't entirely clear if Auspisticing would count, considering it lies in what is, for lack of a better term, the platonic half of troll relationships.[[/note]]
* ''[[http://www.hackcanada.com/canadian/zines/spacemoose/time_machine.html Space Moose]]''.
* [[http://overcompensating.com/posts/20060425.html This]] strip of ''Webcomic/{{Overcompensating}}''.
* In a ''Webcomic/QuestionableContent'' filler strip, Tai [[GenderBender turns all the men in Northampton into women]]; Marten now looks exactly like Dora, so, [[MemeticMutation just as planned]], [[http://questionablecontent.net/view.php?comic=955 they start to make out in front of her]].
* Used in [[http://www.smbc-comics.com/index.php?db=comics&id=880&override=1#comic this strip]] of ''Webcomic/SaturdayMorningBreakfastCereal''.
* ''Webcomic/RealLifeComics'':
** Subverted in a strip: Greg and Tony travel to an alternate dimension where everyone is gender-flipped. Upon meeting female Greg, Tony comments that female Greg is kinda hot. Greg's reaction to this is [[{{Squick}} not surprising in the least]].
** Played straight later, when it's revealed by female-Greg that male-Liz is dead. Greg cheerfully tells Liz and female-Greg [[http://www.reallifecomics.com/archive/080916.html "If you two want to hug, don't stop on my account."]]
** Subverted later still, when Greg's female doppleganger offers to swing by and start hanging out with Greg and Liz, Greg replies with: [[http://www.reallifecomics.com/archive/081104.html "You freak me out in ways I'm not comfortable dealing with. No offense."]] Needless to say, female Greg is offended.
* In a ''Webcomic/Persona3FTW'' strip on the release date of the PSP version of ''VideoGame/{{Persona 3}}'' (which allows you to pick a female main character), both the main character and his female counterpart meet, [[http://www.drunkduck.com/Persona_3_FTW/5186356/ and well...]]
* While ''[[Webcomic/UmlautHouse Umlaut House 2]]'' only implies a [[TwinThreesomeFantasy threesome between Saundra, her husband Volair, and his future self]]... well, it ''is'' [[AnythingThatMoves Volair]] we're talking about.
* ''Webcomic/ElGoonishShive'':
** Done with Tedd and Grace [[http://www.egscomics.com/?date=2003-05-13 go on a date]] [[spoiler:while body-swapped using the TF gun]]. This is commented on later [[http://www.egscomics.com/?date=2005-02-11 here by Tedd]] and then referenced [[http://www.egscomics.com/?date=2006-02-06 here by Elliot and Sarah]] with interesting parallels.
** [[http://www.egscomics.com/?date=2011-07-14 Panel 3 here]] has a strong suggestion.
* ''Webcomic/{{Buttersafe}}'', [[http://buttersafe.com/2010/02/11/biology-101/ with prokaryotes]].
* In ''Webcomic/TheAdventuresOfDrMcNinja'', when [=McNinja=]'s clone is captured, he insists that his father call to make sure that they really have him, and also to [[http://drmcninja.com/archives/comic/17p31 "ask him what he's wearing!"]] Of course, this was InnocentInnuendo that helped the Doctor formulate a plan. That didn't stop his dad from running with the idea and later [[http://drmcninja.com/archives/comic/17p85 assuming that he's making out with his clone]], because "It's what any of us would do!"
* A variation in ''Webcomic/ProblemSleuth'': Problem Sleuth and Pickle Inspector's love interests, Hysterical Dame and Nervous Broad, are also mystic [[DistaffCounterpart Distaff Counterparts]] created while on a VisionQuest. Luckily for us, Ace Dick's counterpart, Ace Dick In A Bad Wig, is slain before the two can form any sort of [[BrainBleach romantic attachment]].
* ''Webcomic/{{Subnormality}}'':
** The comic made this a punchline to [[http://www.viruscomix.com/page389.html an early strip]] (later [[http://www.cracked.com/article_18715_everyones-dream-someone-elses-nightmare-5Bcomic5D.html featured on Cracked]]).
** And [[http://www.viruscomix.com/page425.html this comic]] about the future, where a couple has an argument, the girl breaks up and gets a clone of herself from a vending machine with the explicitly stated reason to have "traditional sex" with herself to spite him.
* ''Wicked Powered'' has this as the origin of the main character. Due to a complex sequence of TimeTravel, [[GenderBender genderbending]], and [[LaserGuidedAmnesia amnesia]], he became both of [[MyOwnGrampa his own parents]]. And this made him immortal. Oh. And his "aunt" is actually his pet monkey.
* Touched on in ''Webcomic/ASofterWorld''. "I would totally make out with my clone. If it was okay with her. No pressure."
* Erin from ''[[http://dragoncity.thecomicseries.com/comics/ Dragon City]]'' has admitted to being attracted to an alternate universe version of herself, but her dad pointed out that she might just be narcissistic. It's later heavily implied that they did have sex.
* When he first gets turned into a woman, after a night of drinking Tiffany of ''Webcomic/{{Exiern}}'' remarks that she's not as turned on looking at her new body as she thought she would be. Followed by a moment of BrainBleach at the thought of checking herself out.
* ''Webcomic/TheNonAdventuresOfWonderella'':
** In [[http://nonadventures.com/2010/04/17/color-bindness/ one strip]], the main character is split into two individuals, each representing a part of her personality. One Wonderella asks whether they have to have sex with each other to fix the problem. The other Wonderella says she's straight but is willing to "lay back". Doctor Shark eventually solves the problem without any intercourse.
** A [[http://nonadventures.com/2013/11/16/lovely-rita-mirror-maid/ later strip]] features Rita making out with her EvilTwin from an AlternateUniverse.
* ''Webcomic/{{Subnormality}}'' barely averts this [[http://www.viruscomix.com/page569.html in the Museum of the Theoretical]], where a woman goes to find out how her life might have been different.
* ''Webcomic/GhastlysGhastlyComic'' has Alan Moore yaoi. Literally.
* ''Webcomic/{{Oglaf}}'': The sorcerer's duplicate phantasms do this in "Mirror Image". According to the phantasms, the sorcerer usually jerks off while they do this.
** One of the bonus comics features a sex-based superhero, Doppelbanger, whose specialty is turning into and acting like whoever they're seducing.
* In a FlashForward of ''Webcomic/SabrinaOnline'', Zig Zag enjoys a VR simulation that lets users have sex with her likeness.
* [[http://www.penny-arcade.com/comic/2016/04/08/quanta This]] ''Webcomic/PennyArcade'' strip.
* ''WebComic/GrrlPower'': [[MesACrowd Harem]] is bisexual, and has dropped hints more than once that she has at least experimented with this with at least two of her bodies. The phrase 'paralytic cunnilingus' was bandied about (it was [[HornyDevil Dabbler]] who brought it up, but in a 'mini-panel' at the bottom, one of the Arc Light agents, Gwen, expressed envy over the idea, Harem made a sort of 'been there, done that' reply, followed by [[http://grrlpowercomic.com/archives/1238 "Oh, like you wouldn't [try it if you could]!"]]).

[[folder:Web Original]]
* In the ''Literature/WhateleyUniverse'', this is a serious problem to Jobe, as his now-identical clone Belephoebe is also in the body of his ideal girlfriend. And is his daughter, legally. He restrains himself from the urge to make sweet monkey love to her. [[spoiler:Even after Jobe is turned into a girl. Belephoebe, however, does NOT restrain herself.]]
* Invoked, and very nearly practiced, by Doctor What in ''Script/AHDotComTheSeries'' "The Narcissus Syndrome"--with his evil, MirrorUniverse, GenderBender counterpart.
* Website/{{Cracked}}:
** The website ran a column by Dan O'Brien entitled [[http://www.cracked.com/blog/human-clones-do-you-fk-or-fight/ "So You're Locked in a Room with Your Clone: Fight or F#@k?"]]
** Cracked also ran a video in which Swaim speculates about having sex with his own clone. He decides that the morning after would be akward.
--->'''Clone #1:''' What do you want to do?\\
'''Clone #2:''' I... want to die.
** And then ''Agents of Cracked'' had an episode featuring a SimilarSquad, with Dan O'Brien's doppleganger invoking the article written by his counterpart.
--->'''Brian O'Donovan:''' You know, I remember reading somewhere that there are only two truly meaningful things you can do with your doppleganger when you're locked in a room. You can [[MirrorMatch fight them]]... Or f#@k them.\\
(''Dan takes a fighting stance'')\\
'''Brian:''' Wrong answer.
** A later episode has Swaim reference this incident, and then provide many potential alternate names for this trope.
--->'''Swaim:''' You slept with your exact duplicate. The clone bone. Sixty-sixing. Dopplegangbang. Mirrorbation. The big auto-erotic enchilada. Twins with benefits.
* In the Funny or Die video "Go Fuck Yourself with Dave Franco", the titular Franco goes to a bar, hooks up with himself, and eventually fucks himself. The [[http://www.funnyordie.com/videos/f211d50fbc/go-f-ck-yourself-with-dave-franco?rel=player link]] is slightly NSFW.
* ''WebOriginal/OrionsArm''
** House Stevens is made up entirely of clones. Their progenitors were the 47 survivors of an early colony ship that suffered a massive CryonicsFailure and they began to reproduce by cloning in order to avoid inbreeding. To prevent "accidents" they made homosexuality mandatory and over the centuries it became tradition to only have sex with others within their own clone.
** Also implied to be happening at the end of ''Betrayals'' between Gus and a copy who had been living in a virch for years.
* In the ''Roleplay/GlobalGuardiansPBEMUniverse'', a muckraking tabloid once accused superher Los Hermanos of having done this. While he denied he ever ''had'' done so (or even having ever thought about doing so), he also shocked his teammates by admitted that the idea wasn't as repugant to him as they thought it should be as, given that he and his duplicates are a HiveMind, it would be more akin to masturbation than anything else.
* Lampshaded in ''[[http://www.nwdrizzle.com/drizzle/archives/archives.html#mel MEL]]'' when the eponymous protagonist ends up with not only his love interest but an [[FutureMeScaresMe older version of her]] from a future where she was embittered by HIS death.
-->"He was fiercely aroused all of a sudden, and he realized that his situation was somewhere in between ''The Graduate'' and the lucky guy who gets to take home those blonde beer-ad twins--no incest taboo, just something more sublime and disturbing. He didn't want to think about it too earnestly, for fear of blowing up the universe."
:: It doesn't last however, as the two versions leave him for ''each other''.
* ''WebVideo/RhettAndLink'' [[http://www.youtube.com/user/RhettandLink have]] [[http://www.youtube.com/watch?v=QUvLZeDgU-c&feature=feedu this video]] about choosing the perfect profile picture. After taking the appropriate steps and multiple shots, "pick the one picture in which you are most physically attracted to yourself".
* Website/CollegeHumor:
** ''[[WebAnimation/DorklyOriginals Dorkly]]'' gives us the following line in [[http://www.youtube.com/watch?v=NggUSbgRUhc "Wish I Had a]] [[VideoGame/{{Portal}} Portal Gun"]]:
--->"I'd shoot two portals in a vertical line, undo my belt, lean in, and... [[spoiler:[[SubvertedTrope change pants without having to look down.]]]] ''({{beat}})'' [[spoiler:[[DoubleSubversion Also I'd suck my own diiiiiiiiiick!]]"]]
** Also parodied in ''[[http://www.collegehumor.com/video/6853540/looper-has-sex-with-himself Looper Has Sex with Himself]]'', spoofing the movie ''Film/{{Looper}}''. The TimeTravel in the film is employed specifically to invoke this, but the duplicate versions of Old Joe can't agree on who is going to give who oral sex.
** And in their [[http://www.ign.com/videos/2010/03/31/back-to-the-future-sex-scenes spoof]] of ''Film/BackToTheFuture'', a [[OutOfCharacterMoment disgusting]] version of Marty ends up [[{{Squick}} having sex with his own mother]]. Doc is horrified by this, and sends Marty back in time to stop this from happening--only to end up with Marty having a threesome with his mother ''and himself''!
* In ''WebVideo/TheNostalgiaCritic''/''WebVideo/AtopTheFourthWall'' Linkara[=/=]Mystery Science Theater 4000 riff of ''Film/DragonBallTheMagicBegins'', when "Oolong" turns into "Bulma" (after turning into [[FanDisservice himself in bad drag]]), the guys immediately start shouting things like "Touch each other!"
* WebVideo/TheNostalgiaChick reviews ''Film/TheWorstWitch'' movie, which includes a Creator/TimCurry song with a variety of weird visuals. One is Curry's face doubled, with the reflections face-to-face with each other.
-->'''Tim Curry:''' ''Anything can happen on Halloween--''\\
'''Curry!Chick:''' ''I could make out with myself/That would be pretty keen!''
* In ''Blog/CinnamonBunzuh,'' an ''Literature/{{Animorphs}}'' ReviewBlog, reviewer Ifi ships Ax and Tobias ([[IncestYayShipping who are uncle and nephew]]) while the latter is morphed into the former.
* In ''Literature/TalesOfMU'', during an experiment with an enchanted box that creates duplicates of whatever is inside it, [[spoiler:the elven teacher Acantha]] makes out with her duplicate for a bit before being interrupted.
* In their crossover review of ''Film/MyraBreckinridge'', when presented with the scene of Myra performing oral sex on her [[{{Transgender}} pre-op]] self Myron (long story):
-->'''WebVideo/TheCinemaSnob:''' And they're the same person?!\\
'''WebVideo/DiamandaHagan:''' Yep.\\
'''The Cinema Snob:''' Is this ''masturbation''?\\
'''Diamanda Hagan:''' Oh fuck I hope so.
* Website/SFDebris's theory regarding the reason Janeway of ''Series/StarTrekVoyager'' always argues with herself when time travel gets involved: ''UnresolvedSexualTension''. Cue a brief montage set to the Divinyls.
* Wiki/{{SCP| Foundation}}-[[http://www.scp-wiki.net/scp-1587 1587]], a machine attached to a bed that makes whatever you dream about become a real place and teleports you there. One of the tests by its inventor didn't turn out the way he hoped.

[[folder:Western Animation]]
* A sketch on ''WesternAnimation/RobotChicken'' parodying Best Week Ever, featured Hal Sparks (portrayed as pretty much all people on that show are, as a stop motion action figure) remarking "If anyone ever made a toy of me, I'd have to make out with it". A few seconds later, Hal is shown making out with a considerably less animate but otherwise identical copy of himself. A moment after THAT, he pauses to cheerfully declare to the camera, "It's not gay, it's masturbation!"
** Another sketch had a "doppelgangbang", where a bunch of people with the same face but different bodies engage in an orgy.
* ''WesternAnimation/{{Futurama}}'':
** It's nowhere near sex, but [[spoiler:Fry does say Lars has a "ruggedly good-looking face," before he learns [[MyFutureSelfAndMe Lars' true identity]]]].
** This is of course the very first thing a nudist alien does after thinking he finds the secret to paradox-free TimeTravel in ''Bender's Big Score''.
* In one of its countless {{Imagine Spot}}s, ''WesternAnimation/TheSimpsons'' had Homer fantasizing what it'd be like to marry himself. Cue the image of a room full of mini-Homers and two adult Homers swapping tongue.
* Arguably, Warden paired with either himself or his future self is one of the more popular pairings in the ''WesternAnimation/{{Superjail}}'' fandom, fueled by a scene in which two versions of himself hug each other at their trial, prompting the judge to tell him to [[SugarWiki/FunnyMoments "stop touching yourself!"]]
* In the ''WesternAnimation/{{American Dragon Jake Long}}'' episode "The Love Cruise", Fu accidentally gets shot by Cupid's love arrow and falls in love with himself.
* While Cybertronians are by and large immortal robots who realistically would only have a PurelyAestheticGender, Starscream in ''WesternAnimation/TransformersAnimated'' seems to come on to his OppositeSexClone, Slipstream, while asking what she represents in him.
* An episode of ''WesternAnimation/FamilyGuy'' features Stewie and Brian travelling to other universes, one being where everyone has two heads: One happy, one sad. When we see this universe's Stewie, we see his heads kissing each other. The happy one likes it, while the sad one tries his best to.
** There was a cutaway gag in another episode about a "narcissistic pedophile" who masturbates to childhood photos of himself.
* ''WesternAnimation/AeonFlux'' has an episode where Aeon is duplicated and, true to her omnisexual nature, makes out with herself, though only briefly... on camera. There was more than one duplicate. And they were all naked, in the same room. Yes, the BigBad had a cloned harem of his [[FoeYay primary nemesis]].
* In one episode of ''WesternAnimation/{{My Gym Partners a Monkey}}'', Jake has a parrot named Orlando who keeps looking at himself in the mirror and saying "pretty bird".
* An episode of ''WesternAnimation/AmericanDad'' has a future version of Stan offering the Stan from the present a "handy J." According to future Stan, it's not gay, it's "you on you."
* On ''WesternAnimation/YoungJustice'', Miss Martian demonstrates her shapeshifting powers by turning into female versions of Robin and Kid Flash, leading Kid Flash to wonder, "Is it wrong that I think I'm hot?"
* ''WesternAnimation/FairlyOddParents'' has the episode "Stupid Cupid" where Cosmo falls in love with himself after he accidentally shoots himself with Cupid's love arrow.
* ''WesternAnimation/MaryShelleysFrankenhole'':
** Creator/RonHoward (and Creator/TomHanks, but only incidentally) was so narcisistic that he forced hookers to wear mirrors on their faces. Eventually, that wasn't enough for him, so he wanted Frankenstein to make a clone of him. He agreed, but Ron felt it was taking too long and started jumping back through time to have sex with younger versions of himself. This ultimately collapsed the timeline and resulted in a universe populated by an infinite number of Ron Howards.
** Also with the Were-Lawrence. He finally finds a woman who loves him. Only, having bitten her, she turns into his human form whenever sexually aroused.
* In the episode "Johnny Alternative", it's strongly implied that ''WesternAnimation/JohnnyTest'' falls in love with a female version of himself.
* A PG version in the episode "A Glitch Is A Glitch" of ''WesternAnimation/AdventureTime'', in which the [[AbhorrentAdmirer Ice King]] is convinced that Princess Bubblegum will go out with him if he was the last person in Ooo. His evil scheme of the episode does indeed remove everyone from Ooo, but when he comes to collect, Princess Bubblegum realizes that there is one person in Ooo other than the Ice King--herself. She proceeds to spend most the episode's remaining run time making out with her own hand.
* In ''WesternAnimation/SheZow'' Maz is attracted to Maisy, his female double from [=DudePow=]'s universe, from the moment he sets eyes on her. Kelly also suggests that the reason [[WholesomeCrossdresser Guy]]/[=SheZow=] and [[DistaffCounterpart Gal]]/[=DudePow=] bicker might be because [[BelligerentSexualTension they could really like each other]], also the [[AnIcePerson ice powered]] villain [=ColdFinger's=] and his [[PlayingWithFire fire powered]] female counterpart Grilla also hit it off.
* [[DistaffCounterpart The Newmans]] aren't genderbent versions of ''WesternAnimation/GrojBand''. They're completely different people who happen to share a physical resemblance. So don't worry fanfic writers. You can have the two bands fall in love and it won't be gross at all.
* Another PG version happens in the ''WesternAnimation/TotallySpies'' episode "Future Shock"; Sam, Alex, and Clover give their adult selves some rather suggestive victory hugs after taking Mandy down.
* A PG version in the end credits of ''WesternAnimation/SmurfsTheLostVillage'': Vanity Smurf's reflection comes to life and gives him a kiss on the lips.
* ''WesternAnimation/BumpInTheNight'' touched upon this trope in the episode "Gum Crazy", where Mr. Bumpy [[DisguisedInDrag disguises himself as a woman]] in an attempt to seduce his heart to give up the gum inside his stomach. The personification of Bumpy's heart happens to look like Bumpy with a moustahce, and Bumpy's ruse is thankfully foiled before things get too risque.
