Beanball

Beanball is an enemy from Mega Man ZX. It appears as a blue circular "head" on top of a stand that swings back and forth like a pendulum a few times before launching a small ball at the player, very similar to a catapult. Beanball only appears in Area K Lava Field.

Etymology

 * The word "Beanball" means to intentionally hit a batter in the head on purpose.
