What are some heroes you'd like to see turn villain and villains you'd like to see go hero.
I've been wanting Mystique to become an X-Men even sense they let Magneto join. Hell they even let Siberian Saw be a good guy. I think she'd fit in pretty good in the new sexy lady X-Force to, or it would be pretty great to see her as a Teacher.
I think it be really interesting to see Damian become one of Batman's greatest failures and become a villain.
