I've been thinking after my Gauntlet run was ended, about which character could be considered the most OP. Killer Prime, Final Frontier Eddie, Assassin Banshee and Icarus are all candidates, but I think it would be Redan.
Sure KP and FFE (plus some others) are really heavy hitters, but Redan is just so powerful on so many levels. Her passive can elevate an average team to victory, and every attack you do against a team with her risks doing more damage to your chances than to the other team. Her passive is also harder to neutralise than Banshee on top of all of that.
Heavy hitters and powerful passives can be tackled on the first turn, but even winning the coin toss won't really help against Redan. Anyway, what are your thoughts?
P.S.- Yes I am also a bit salty that I didn't get Daedalus, the Count or Redan in their heroic soul appearances.
