Shield Cannon

Shield Cannon in Mega Man: Powered Up

The Cannon (ホウダイ Houdai?) is an enemy in Mega Man 3. They are mostly found in Needle Man's stage (both main mission and when Doc Robot appears). They are only vulnerable when they're shooting. When a Cannon is inert, a metallic hatch covers its weak spot. If one senses an enemy, the Cannon's hatch will raise and extend a barrel that launches a large cannonball. Mega Man must attack the barrel of a Cannon to inflict damage. In Mega Man II, they also appear in Wood Man's and Needle Man's stages.

In Mega Man: The Wily Wars, they appear in the 3rd Wily Tower Stage.

In Mega Man: Powered Up, they are called Shield Cannon and have minor changes such as different colors, and they now have eyes. They only appear in challenge mode stages, and stages created with the Construction Mode.

They also appear in a mini-game from Mega Man ZX Advent.
