The Plug Ball (プラグボール Puragu Bōru?) is Plug Man's special weapon from Mega Man 9. Mega Man shoots out spark balls to shock enemies. The sparks will travel along the terrain. If fired in mid-air, the sparks will fall directly down and will then travel along the terrain upon contact with it. The Plug Ball is Tornado Man's weakness, his movements placing him close enough to the walls that you can hit him without having to aim. It also neutralizes any tornadoes it touches.
