History ScrewYourself / FanWorks

* Pairing between both the male and female Protagonists of ''VideoGame/{{Persona 3}}''', who are alternate versions of each other, is rather popular among fandom and is even teased in ''VideoGame/PersonaQ2NewCinemaLabyrinth'' in which their first interaction looks like LoveAtFirstSight along with their sense of familiarity with each other, which causes both Junpei and Teddie to believe they are soulmates.

* ''Manga/RanmaOneHalf''y9jfiuy7u
j : There are 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.)

* 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.

* ''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.

* ''Franchise/{{Transformers}}'': A work featured on Archive of Our Own and Website/FanFictionDotNet is one about Smokescreen (the young adult/late teen version from Transformers Prime) being shipped with his Shattered Glass version, titled "Gettin Off On You Getting Off On Me". Obviously NSFW.

* ''Manga/RanmaOneHalf'': There are 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.)

** 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:

* The fandom for ''WesternAnimation/TheLorax'' is [[https://www.youtube.com/watch?v=us5Y_Kba7To rather infamous]] for shipping the Onceler with himself, most often via shipping the version of him seen early in the movie with a version of him from after his business becomes successful, with the latter being referred to as the "Greedler", as seen in fanfics such as [[https://archiveofourown.org/works/22287751 this.]]

** There is a fic for Danny and his AxCrazy future self: ''[[http://www.fanfiction.net/s/3317236/1/Narcissism Narcissism]]''. It's quite horrifying, and sadly a DeadFic.

** 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.

* ''LightNovel/HaruhiSuzumiya'':

* The [[Machinima/Supermarioglitchy4sSuperMario64Bloopers SMG4]] fanfic ''[[https://www.deviantart.com/masterperrymartin/art/Love-is-Dumb-Meggy-x-War-Meggy-APRIL-FOOLS-875014218 Love is Dumb]]'', a self-confessed CrackFic, ships [[spoiler:Shadow ]]Meggy with herself. The other Meggy is a corrupted counterpart who [[CaptureAndReplicate kidnapped and brainwashed the original Meggy]] to live her life, but struggles with her own feelings of love...[[spoiler:until Shadow Meggy breaks free and effectively seduces her. Subverted when it's all revealed to be a nightmare from an also corrupted Tari.]]

* In the ''Fanfic/InfinityCrisis'' spin-off fic ''Brothers of Thunder'', when the Avengers of Earth-12041 (as depicted in ''WesternAnimation/AvengersAssemble'') arrive in Earth-911111 (a world that is basically a gender-inverted version of the Franchise/MarvelCinematicUniverse), Hawkeye of Earth-12041 is genuinely bemused when he realises that Tony is literally flirting with his Earth-911111 counterpart.

* In the ''MCU Loki(2021)'' fanfic [[https://archiveofourown.org/works/34085143?view_full_work=true Crossworlds]], two of the Loki variants (the canon variant who escaped from TVA and an Avenger!Loki variant) end up in a compromising situation which leads a squicked out Fandral and Sif to suspect this is happening. Neither Loki bothers to correct the assumption.

** The fandom generally paints background pony Cloud Kicker as a LovableSexManiac. When circumstances result in a [[spoiler: Changeling [[ModeLock modelocked]] into Cloud Kicker's shape]] at the end of Fanfic/EakinsHardReset, this trope is implied.

** 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 [[https://www.youtube.com/watch?v=Ck-VIA1GUCY managed to use]] ManipulativeEditing on some episodes of ''Series/StarTrekTheNextGeneration'' to make this come true on screen.

* ''WesternAnimation/MiraculousLadybug'': It's recently become popular to ship the two main characters, Marinette and Adrien, with their superhero alter-egos, Ladybug and Chat Noir. Not helping matters is that it is theoretically possible for this to happen InUniverse with the [[MesACrowd Mouse Miraculous]].

* ''Series/DoctorWho'': 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 live journal 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.

** 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.]] (Link is dead)

** ''Fanfic/AftermathOfTheGames'': Referenced only - Pinkie's first response when the two Twilights first meet is "Quick, make out with yourself!". They don't.
