It's different than what I had in mind, but I'm liking it in a specific way -how I see this character working in the RP would be like, a character the "starting characters" meet up with later, while they're already into their own discovery journeys. Like a mid-way point entry character, though probably sooner than mid-way.

This type of character could add another layer to things given the differences to the others with the only similarity I'm seeing so far being they want to know the truth. 

That is, I'm picturing they're on their own, not living at the Mansion / not really having been raised by any of the X-Men, but perhaps you had a different idea there?
