Energy Cannon

Energy Cannon (エナジーキャノン) is a cannon enemy from Mega Man ZX. It appears as a yellow cannon on the ground with a blue protective hatch on the top. The hatch opens up just long enough to fire an energy blast from inside. If left undestroyed, it will have time to learn how to more efficiently utilize energy for more powerful attacks, the energy sphere growing larger in size each time it opens to fire. The sphere can also be fired in almost any direction to follow the player. Energy Cannons appear in Area E Power Plant, Area J Ocean, and Area D Highway.
