The Marvel Mangaverse
It doesn’t tick off all of those categories, but it was definitely controversial, strange and sexual. It took all the superficial things about manga and left out all creativity that makes manga great. So what you got was a twisted Marvel Universe that was sexist, racist and just overall offensive. Not to mention the worst crime of all, it was poorly written.
This may be a controversial pick because a lot of people liked this series, but a lot hated hated it and I’m one of them. The story centered around the rape, torture and murder of Elongated Man’s pregnant wife. I understand DC was trying another “dark” story, because they are good at those. But this went too dark and was just unpleasant to read. The only good thing about it was it directly led into a far superior DC series, 52.
Superman The Porn Star (AC #592 & 593):
This is a story I recently read just last year. During John Byrne’s run on Action Comics he did some interesting things. The craziest was the creation of a new character called Sleeze, who was so depraved he was kicked off Apokolips. Yeah. So Sleeze, wanting to make some cash, brainwashes Superman and Big Barda to make a sex tape togeather. Yeah. Fortunately Mister Miracle stops the production before anything could happen. But still, goddamn.
The Rape of Nightwing by The Second Tarantula, Catalina Flores
Yeah, DC is on here a lot for some reason. But anyway, the most infamous male rape in comics happened in Nightwing #93. Tarantula had a longtime crush on Nightwing, so in order to show her affection she kills Blockbuster who had been his longtime foe. But then she goes a little to far and takes advantage of Nightwing who was weakened after the battle. And by “take advantage of” I mean she forcefully rapes him with Nightwing moaning "don’t touch me!" throughout the ordeal. Maybe some wouldn’t call that rape, but I’m gonna go on a limb and call that rape.
Gwen Stacey Impregnated By Norman Osborn (ASM #509-515)
File this under “incredibly fucking creepy and disrespectful”. It’s not enough that Osborn was indirectly responsible for Gwen’s death, but he first got her pregnant during a torrid affair while she was dating Peter. She later gave birth to twins while in France and wanted to raise them with Peter.
The twins would age rapidly because of the Goblin serum and eventually come back to fight Spider-Man. So Gwen, instead of being a tragic tale of the innocents who get caught in the crossfire between good and evil, becomes a hussy ready to jump in bed with any wealthy businessman she came across. Nice.
Well, there’s 5 for you. Comics can be pretty fucked up sometimes.
