If you are familiar with the X-Men, then this poll is for you! Which X-Man's mutant power would you want? For the purposes of this poll, let's say you get their weaknesses and limitations too. So, for Professor X, it means being in a wheelchair. For Cyclops it means not being able to take off your glasses without releasing your optic blasts, etc. (although he can just close his eyes too). Rogue can't touch anyone. Etc., etc.
Obviously there are way more X-Men than the ones I listed. I tried to keep it to the most prominent ones, and left out characters like Cable whose powers are sort of indeterminate, or Jubilee, who's just stupid. But obviously any and all are fair game.
