10 Most Inappropriate Marvel Comics Storylines Ever
6. The Ultimate Maximoffs
As the MCU is beginning to delve into recently with the likes of Spider-Man: No Way Home, Loki, and Doctor Strange in the Multiverse of Madness, there is more than just one reality. The continuity of the Marvel Universe is made up of a multiverse, which leads to literally infinite possibilities.
The Ultimate Universe is one such alternative to Earth-616, and has been home to, among others, alternate versions of classic Marvel heroes like Miles Morales. Not every character, or every change has been quite this successful however, and you need go no further than the Maximoff twins for proof.
Though regular twins on Earth-616, or at least as regular as mutants can be, the Ultimate versions of Wanda and Pietro Maximoff grew far closer than brother and sister ever should. With Magneto's unashamed abuse of Pietro, he was driven into the arms of his sister as both a sibling and a lover.
This isn't Game of Thrones, and it should surely go without saying that incest should have no place in the pages of a Marvel comic book.
