Since BP was introduced as someone who solo'd the entire Fantastic Four, I figure this has to be much less of a murderstomp than the white version: Batman vs Superman (btw, without PIS, Clark beats Bruce, all day errday).
T'Challa vs Adam Brashear.
Round 1: standard rumble settings, standard gear.
Round 2: each gets 1 day prep before going to the arena, no backup
Bonus Round: to complete Marvel's Black Trinity: Storm enters the arena. How does Ororo Munroe do against either in single combat, standard Rumbles settings?
