5. Professor X

(The Uncanny X-Men, Marvel Comics)

Ah, yes. The patriarch of the X-Men.

Professor Charles Xavier was one of those characters who died and come back more times per year than I re-watch my favorite movie (Zodiac, if you were curious). He also bounded in and out of that chair like it’s a playground hopscotch course. But I'll focus mostly on why he shouldn't still be around.

I recently read the absolutely incredible X-Men: Grand Design, which is Ed Piskor's X-Men historia that’s done in a beautiful and fascinating way. It was fascinating to see Xavier as mentor and the way the other X-Men grew over time. I mean, we went from a five-student First Class to hundreds of X-People spread across numerous teams. So why is Xavier still around?

Let his dream live on, let new people lead. But him? He doesn't need to hang out anymore.
