Cannon Gun

Cannon Gun is a Heartless that appears in Port Royal, Land of Dragons and Space Paranoids. Unlike most aggressive Heartless attack tactics, it avoids you as much as possible. Its main attack includes creating a target emblem on the floor tracking you, and fire cannon bombs(as the name implies) while you're not cautious. Cannon Gun can be an annoying enemy, especially when paired with aggressive Heartless, since they are good attack supporters. A good way of finishing them quick is to cast Magnet on attract them and finish them of with a strong spell. Alternately, changing into Wisdom Form and sniping from afar is also a good tactic, since Sora can move while attacking in this form. Also, Sora is considerably faster in normal form as well, So it may be chased after.
