|Screw Crusher's concept art in Mega Man 10.|
It consists in a short range, parabolical rotating blade. No more than four projectiles can be at the same time onscreen. If the enemy has 1 HP, the crusher will pass through it, but it will not if the enemy has two or more. It can pass through terrain. This weapon is useful to attack enemies over the player character, to repeatedly attack a close target or to attack enemies with a frontal shield that are vulnerable elsewhere, like some Sniper Joes.
Unlike its appearance in Mega Man III, it cannot destroy Garyobys.
