Mirror Buster

Mirror Buster (ミラーバスター) is Enker's special weapon. When used by Mega Man, it creates an energy shield that reflects an enemy's shots back at the one who shot it. It also does not cost any weapon energy unless a shot is actually reflected of it. The downside is it only protects Mega Man from the front, leaving his other sides vulnerable to attack. It is the only weapon that can hit the Wily Machine's final form in Mega Man: Dr. Wily's Revenge.
