Cannon

Cannon, known as Houdai (ホウダイ) in Japan, is an enemy from the original Mega Man series. When a Cannon is inert, a metallic hatch covers its barrel. If a Cannon senses an enemy, its hatch will raise and extend a barrel that launches a large cannonball. They are only vulnerable to attacks while the barrel is exposed, being its weak spot.
