Cannon Base

In the first Mega Man Star Force game, Cannonbases (キャノベース) appear as standard enemies that sometimes appear with Mettennas. They appear as blue cannons pointing up with faces. When the player stands in front of them, the Cannonbase will then fire a bomb at them. They sometimes give the Battle Card PowerBomb. When Powerbomb is used, the bomb will explode into a cross rather than onto a single space. The upgraded versions are Megabases and Gigabases, which are simply red and purple palette swaps. The Megabase fires bombs into an X and the Gigabase fires bombs into 3x3 spaces.
