She's one of those mutants like magneto who manipulates a fundamental force of the universe (matter/energy for her) that can be read as 'she manipulates the universe', so her powers are 'whatever the writers feel like at any given time'.
Visually she's been 'every perky teenage dark haired marvel character ever', 'raven from teen titans, except ugly' or 'jack from mass effect (current)'.
Very blase sarcastic attitude. Died once, undied. Still not dead.
Very generic character in terms of personality mostly famous for appearing with Deadpool (even though that was effectively an entirely different character) and extremely stupid codename.
Also she probably won't ever change the dumb name. Its the point. She doesn't give a ****. That's her schtick. Especially since they keep making her stronger so she'll probably never learn any humility or anything.
