I’m maybe in the minority in that I don’t really care for Jubilee or Dazzler, the two front runners, although of the two I’d rather have Jubilee. My vote is going to Cannonball. He’s one of my favourite characters and it’s a shame he’s been benched for so long, especially since Sunspot is getting a showcase in X-Men Red.
I wouldn’t mind Juggernaut either, although I don’t know if/how the character has been tarnished by Legion of X…
