Screw Yourself / Comic Books

• Jamie Madrox (a second-string 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, The Sentry and the Void are both alter-egoes of the same man, split into two bodies, who have passionately kissed on at least one occasion. Void tells Sentry he loves him and then aggressively tongue kisses him. Sentry responds by tossing Void into the Sun!, so he obviously didn't enjoy it.
• Supergirl has an alternate-universe doppelganger named Power Girl, 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, 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. Guess what day they announced it on? The fans were not amused.
• 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 the Jaeger-monster is the Anthropomorphic Personification of his anger, Finder's Magri White declares that he can do as he pleases with him, and proceeds to play tonsil hockey with him.
• Played with in Cerebus the Aardvark. Cerebus learns about halfway through the series that he is a hermaphrodite whose genital arrangement could have led to him impregnating himself if his uterus had not been permanently damaged when he was a child.
• 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 Little Nemo), 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 an issue of Tom Strong's Terrific Tales, Jonni Future is on an alien world where her reflection in a pond steps out of the pond and begins to kiss her. Then the reflections of both of them step out of the pond, and so on. (Given the similarities it was either an homage or a ripoff of the Little Ego situation above.)
• In Green Lantern 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 Literal Split Personality, 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 Ultimate Spider-Man 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 Super Young Team 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 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 X-Force. 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 Watchmen almost winds up in a three-way involving himself, Laurie, and himself, but Laurie was 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 and he is not really having sex between his many selves but rather they all have with her. 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 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, Rufus and Ruby are already making out.
• 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.
• Dolly from The Long Tomorrow is a Shapeshifting Seducer who tries to stop Pete from killing her by turning into his potential dream lovers, including himself for some reason.
• Battlestar Galactica BSG Vs BSG sees the original Starbuck and his Gender Flipped counterpart, Kara Thrace, sleep together.
• The Magic Order: Just before setting out for the latest assassination, Big Bad Madame Albany orders her shapeshifting second-in-command Lord Cornwall to "turn into something interesting" and remarks that she wants "to fuck something legendary." Cornwall responds by turning into Albany herself - albeit stark naked. Albany is very appreciative.
• The 43rd issue of the Futurama comic book has Zapp Brannigan dream that he hooks up with a woman resembling a female version of himself.
• In The Alternates, the late Divider had the power to divide himself into smaller duplicates. While looking through the Divider's journals to try and find a hint about where he got his hands on drugs that killed him, Mary discovers that he was so bored with his mundane life that he started keeping an exhaustive record of every possible way that he could use his powers to literally go fuck himself. She's so appalled that she almost wishes she could kill him herself just for making her read it.
