Is this the hex sphere/bolt Scarlet Witch?
The Wonderman conjuring, Ultron raping SW?
The crazy-assed superpowerful "I needs me a baby!" SW?
The last one shouldn't of even happened. I mean, she and Vision could've asked Wonderman to be a surrogate (Viz and Simon are basically brothers). Plus, she was already starting to hook up with Cap (and he's been laying pipe since WWII).
SW can just rewrite reality and have her die on an earlier FF mission, or have all of the foes the FF has ever faced gang up on her,or make it so that she never met RR (so she never went on the rocket and even got her powers), she could probably even blink her out of existence.
