Bounce Ball is Bounce Man's Special Weapon in Mega Man 11. After obtaining it, Mega Man can fire a volley of three bouncy balls that can be tilted up or down; each ball ricochets off of walls and enemies a few times before exploding in a burst of confetti. Mega Man can have several shots of Bounce Ball on screen at a time.
If Mega Man uses the Power Gear alongside Bounce Ball, he'll fire three extra balls behind him, making for a total of six balls per shot.
Like all of the special weapons in the game, Bounce Ball changes Mega Man's appearance rather than just being a color swap. In this case, Mega Man's helmet has several white orbs embedded into it, and his arm cannon takes on a slightly bigger shape.
