13. Scarlet Witch And Quicksilver's "Special Relationship"

In the regular Marvel Universe, the twins Scarlet Witch and Quicksilver have a strained relationship. They grew up not knowing their father, and discovering that he was the mutant menace Magneto - with whom they had been collaborating with for years - didn't much help things.

In the Ultimate Universe, though, it was very different. They were much closer. Too close, arguably. As in, they engage in incestuous love making on the regular, and everybody is very horrified by it. Especially Captain America, whose poor WWII brain can't get his head around it.

To be fair, neither can ours, and so far as we know we've never been frozen in a block of ice for centuries. As if that wasn't inappropriate enough, there's also the hints that the pair are actually Wolverine's kids - Logan having had an affair with Magneto's missus not long before she got pregnant - and the above scene is being narrated by the X-Man as he watches from the bushes as the brother and sister get it on.

The brother and sister who may just be his own children. Because that wasn't creepy enough on its own, and needed a whole other level of ew ew ew please make it stop.
