Changes

''[[Armored Alliance]]'' introduces BakuCores that can add [[Baku-Gear]] to the Brawler's Bakugan. These BakuCores have their [[Faction]] symbol in addition to the Faction-based coloration. The latter half of the season also introduce Fusion Cores, which allowed a pair of Bakugan to fuse when they are rolled out onto them. ''[[Geogan Rising]]'' introduced a fourth kind of BakuCore, Geogan Cores, which summon [[Geogan]] to the battlefield. The Geogan replace the Bakugan that the Core is applied to, and once their purpose is fulfilled will return the Bakugan they replaced.
