Artillery

Artillery is a Heartless that appeared on the World of Chaos. They are bluish organic cannons that are attached to the World of Chaos, and shoot blue blasts of energy at Sora as he flies by. A stronger version of them are also present, called Heavy Artillery. When they are destroyed by Sora, Donald, and Goofy, another set respawns after a certain time, but within the time when they're gone attacking the World of Chaos becomes a more manageable task.
