Bombshell
Bombshell made a name for herself at quite a young age. Not many young teenage girls go around robbing banks with their mother. The mother/daughter bank robbing duo was front page headlines a few years ago. There wasn't a bank in New York or Gotham that was safe from their rampage. They were finally captured by some street level heroes. The mother, Lori Baumgartner, was sent to prison while the daughter disappeared from the radar.
Xavier students would probably know some of this to (but not the dirty details) and would be quite familiar with her belligerent attitude and potty mouth.
