I may be interested in this game.
Who are the two combatants for the next round?
Without that I can't judge if anyone I choose is OP or underpowered here.
Granted, powerlevels are in the eye of beholder. They are far from absolute.
I can list feats for Deathstroke and Deadpool which would make them look like demigods compared to normal people.
Doesn't mean they're always portrayed that way.

EDIT: Deadpool and the Bride, huh?
Alright, I'm going to use Solid Snake
