Cannon (or Shield Cannon as it is referred to in Mega Man Powered Up) is a cannon robot. It was originally designed as a defense system to protect against attacking aliens. They are enemies that originate from Mega Man 3 from Needle Man's stage and also appear in Mega Man Powered Up, Mega Man: The Wily Wars, and Mega Man II.
Behavior
When the player is more than 4 tiles away horizontally from Shield Cannon, it will be in its "passive state" where a protective shielding will cover the cannon barrel and protect it from most damage.
When the player is 4 tiles away horizontally from Shield Cannon or less, it will be in its "aggressive state" where the protective shielding will slide away revealing the cannon barrel and will fire two large cannonballs at the player, then briefly covers the cannon barrel with its protective shielding for a few seconds, before looping back to his first behavior firing two cannonballs again if the player is still close to it. The Shield Cannon is vulnerable to damage when its cannon barrel is exposed.
When the player is more than 4 tiles away horizontally from Shield Cannon when it is in its "aggressive state", it will return to its "passive state" after firing its most recent barrage of two cannonballs. Shield Cannon's cannonballs can be destroyed by attacking them or deflected by Shine or Proto Man's Shield. The Needle Cannon weapon can destroy a Cannon in one hit.
Shield Cannon can be selected to face either left or right in the Level Builder; however, due to the way its AI functions, its manual facing direction is redundant, having no effect on how the enemy moves or attacks.
