When she was eleven, Molly Hayes found herself, like all little girls, going through some changes. What she didn't know though, was just how big those changes would be. Together with her best friends, she discovered that their parents were part of a secret cabal of super-villains dedicated to wiping out all the life on Earth in the hopes of giving a promised new and better world to their children.
Oh, and her parents were actually mutants and she had mutant super-strength.
Together though, they fought back against their parents (even if Alex was a super-traitor)and set about being heroes of a kind, trying to make-up for their parents misdeeds. They did good work...
But like all things, it came to an end. When she was sixteen, Molly found herself a member of the X-Men, a position she retains nearly three years later.
