History BrotherSisterIncest / ComicBooks

* Sister/sister incest occurs in Creator/PhilFoglio's ''XXXenophile'' story "The Monster Under the Bed".

* Sister/sister incest occurs in Creator/PhilFoglio's ''ComicBook/{{XXXenophile}}'' story "The Monster Under the Bed".

* Sister/sister incest occurs in Creator/PhilFoglio's ''[=XXXenophile=]'' story "The Monster Under the Bed".

* The ''Franchise/StarWarsLegends'' comic ''Infinities'' explored ForWantOfANail situations in the original trilogy. In a [[WhatCouldHaveBeen rejected script]] by Creator/PeterDavid, the droid Luke Skywalker and his Uncle Owen purchased at the start of ''Film/ANewHope'' never broke down, resulting in Luke never hearing Leia's distress call from R2-D2. In the end, Leia became a Sith Lord and took Luke as her consort as the two never found out they were related. The main issue was that it violated their TheGoodGuysAlwaysWin rule for the series, but the incest certainly didn't help matters.

* ''ComicBook/AfterlifeWithArchie'' (yes, '''[[ComicBook/ArchieComics that]]''' Archie) heavily implies this between Jason and his twin sister Cheryl. He's jealous of Archie and wants to grow old with Cheryl in a place where no one will judge them, while Cheryl refers to Archie as a passing crush while Jason is "family and therefore forever" (while whispering in his ear while dressed as the Literature/RaggedyAnn duo no less).

* In Comicbook/{{Fables}}, [[TheCasanova Jack Horner]] sleeps with three sisters and brags about it, until he finds out that all four of them share a mother, making them half-siblings. The fathers of the sisters are Mr. Revise and the Bookburner.
* During the ''ComicBook/{{Civil War|2006}}'' event, [[ComicBook/FantasticFour Johnny and Sue Storm]] were [[https://chasemagnett.files.wordpress.com/2016/04/civil-war-5-sue-storm-incest-2.jpg forced to hide out as a married couple]] while on the run from pro-registration forces. They are both rather squicked out.
* In an early ComicBook/FritzTheCat story by Robert Crumb, Fritz returns home, and has sex with his sister after they go skinny dipping.
* Tomboy, a short-lived heroine from the tail end of UsefulNotes/TheGoldenAgeOfComicBooks, winds up skirting this trope when her younger brother develops a crush on her costumed persona. Thankfully, nothing really came of it.

* When an alternate version of the Heroes Reborn universe's Rikki Barnes is stranded in the mainline MarvelUniverse, she meets John Barnes, an alternate version of her brother. Unlike her real brother, who was a criminal and a rather unpleasant person in general, MU!John was kind and helpful. Seeing this as a chance to have the kind of caring brother-sister relationship she never had with her real brother, Rikki befriended John. Unfortunately, this John never had a sister, and he misinterpreted Rikki's intentions. He eventually tried to kiss her. When the shocked Rikki tries to tell him that she couldn't love him ''that'' way, John doesn't take it well. At all.
* ComicBook/LesLegendaires: While [[HumanoidAbomination Abyss]] and [[DarkActionGirl Tenebris]] are not technically blood-related ([[spoiler:Both have been created by Darkhell through magic experiments]]), the former considers the latter as his sister. The incest isn't explicitly mentionned, but Abyss' interaction with her had some creepy subtext, with parts where he even openly states he loves her. To add to the creepy aspect, Abyss is a {{Yandere}}.

* Pietro/Quicksilver, of the Franchise/MarvelUniverse, is extremely protective of his sister, Wanda/the Scarlet Witch, and their unusual relationship is implicit in the revamped ''ComicBook/UltimateMarvel''. In the first issue of ''ComicBook/TheUltimates 3'', it's stated outright:
-->'''Wasp:''' You don't get it, Mister Rogers, do you? They love each other.\\
'''ComicBook/CaptainAmerica:''' Of course they do. They're brother and sister.\\
'''Wasp:''' No. It's more than that. They're ''in'' love.\\
'''Captain America:''' But... '''[[GoMadFromTheRevelation they are brother and sister]].'''\\
'''Hawkeye:''' Yep. And if you think we've got problems with that Tony Stark sex video, just wait until somebody in the media figures them out.
** Also in the Marvel universe's Old Man Logan miniseries Bruce Banner/Hulk fathered children with Jennifer Walters/She Hulk as "She's the only woman who can handle me". Subtext strongly implies this was non-consensual.

* The Olympian Pantheon in the Marvel Universe does this. Other pantheons tend to bring this up when they're feeling catty.

* In the French comic ''ComicBook/{{Raptors}}'', a BrotherSisterTeam consisting of two vampire siblings who [[HunterOfHisOwnKind hunt down their own kind]], Drago and Camilla, are in a relationship together.
* Ragdoll of the ''ComicBook/SecretSix'' occasionally mentions his relationship with his sister- among other activities, French kissing and prom night.
** In one Western {{Elseworld}}, the two of them lived together as betrothed.
* In a later issue of ''ComicBook/SpiderManBlackCatTheEvilThatMenDo'', it's revealed that Francis Klum [[spoiler:(who later becomes Mysterio)]] had been repeatedly raped over the course of his life by his older brother.

* In ''ComicBook/StrangersInParadise'', Darcy is clearly coming on to her half-brother David almost every time they see each other. He always pushes her away, but isn't quite as Squicked as he really should be by this behavior.

--> '''Spider''': [[TearJerker He systematically sexually abused her over a two-year period and she missed him. Because he was her brother and she loved him.]]
* ''Franchise/WonderWoman'':

* Fantomex and Cluster in ''Uncanny ComicBook/XForce''. This is a strange situation combined with ScrewYourself; 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.
* ''ComicBook/XMen'' villains the Strucker Twins were always...er...oddly close. Close enough that when Andrea died, her brother Andreas kind of went insane, wrapped the hilt of his sword [[{{Squick}} in her flesh]] (this bit is a little justified - their powers required physical contact between each other), and spent about a year running around like a maniac, demanding of everyone in sight that they revive her.
* Sister/sister incest occurs in the ''ComicBook/{{XXXenophile}}'' story "The Monster Under the Bed".

* In a later issue of ''Spider-Man/Black Cat: The Evil that Men Do'', it was revealed that Francis Klum [[spoiler: who later becomes Mysterio]] had been repeatedly raped over the course of his life by his older brother.
