It has to be The Arkham Knight for me because he's in almost all of my teams. He deals the damage, I have him max augmented and max leveled he does about 29,000 damage per swipe in the swipe combo (with gear). So he knocks out enemies extremely fast and grinding BB6 is so easy because 2 swipe combos knock out the whole enemy team and it takes like 6 seconds. So its definitely him.
