Grand Cannon

Grand Cannon (グランドキャノン) is a cannon enemy from Mega Man Zero 3 that looks like a igloo, as it was made specially for frozen terrain. It shoots energy spheres at various angles.

Trivia

 * Early in the game design, Grand Cannon is called "Eskimo Cannon" (エスキモー砲台), as shown in sketches of Rockman Zero Official Complete Works, and would appear with a unused Yeti sub-boss.
