Eh no reason. I guess I can find some Asian chick to base her appearance off of instead of a Green woman, which would be more difficult.
Not necessarily - a google image search for 'Orion Woman, Cosplay' or 'She-Hulk, Cosplay' might net you a usable image!
how feasible is it to pull off Hank Pym/Antman? I know they have a plan for Ant Man in the MCU where hank simply developed the pym particles and Scott Lang becomes the one to wear the suit. I might have a few other canons in mind though if thats not possible]
Well, *points to second post* Hank Pym is a GM NPC and thus not available for player control at this time. Other than that, there's nothing to stop you making a character who uses stuff Pym has designed. We'll let you know if anything Pym-related in your background needs to be tweaked to match our version of him.
I'd like to reserve Cain Marko aka The Juggernaut.
Cain Marko/Juggernaut is reserved for Juggtacular.
