3. Franklin Richards

Unclassifiable

Shocking! Right? Franklin isn't supposed to be on a list of X-Men characters, he's Fantastic Four, through and through. But the first born of the first family IS a Past-Omega Level Mutant, and he has some crazy powerful abilities.

Franklin was born the son of Reed Richards and Susan Storm-Richards. As a young boy, he began to develop Mutant powers. This is especially shocking, given that most Mutants don't develop powers until puberty. When the being known as Onslaught attacked, he was eventually pushed back, and the combined forces of the X-Men, Avengers, and Fantastic Four destroyed him. In the final conflict, the FF and Avengers seemed to die in combat, but in reality, Franklin used his frankly godlike powers to tear them from reality and place them in a pocket reality that he created.

So, like that spooky Billy Mumy character from The Twilight Zone, but a good guy. In this other reality, later labeled Counter Earth, the heroes had completely different lives that were much worse written and occasionally worse drawn.
