Haha, I love how you said that "BOOM! No more mutants." I guess that is pretty cool.
I don't think Wanda will become the most powerful in the movies and shows though. You know how the Loki show just came out? And all the stuff about the Timekeepers? Well there was a guy in the comics, I forget his name, but he had a box on his head, and he controlled time. I think that guy will have some part in the new Marvel stuff. The shows are really bringing everything really deep.
