First Cannonball was the most successful New Mutant since he was the very first of this team to become an X-Man and later Avenger.
After him several others became X-Men and Sunspot became an Avenger as well.
But now Sunspot becomes a leader of an Avengers team.
Does that make him the most successful New Mutant up till now?
I think many would have guessed Sam or Dani would be.
So how you feel about it?
