The Perfect Core (パーフェクトコア, Pāfekuto Koa?) is the magical entity that holds Vestroia's balance and is the center plot in Bakugan Battle Brawlers. The Battle Brawlers protected it from Naga who wanted to use its power to rule the universe. In the process of the series, Drago has been learning about his origins (and that of the Bakugan species) and has acquired more fragments for the Core. In Bakugan Battle Brawlers: New Vestroia, Spectra Phantom wanted to capture the Perfect Core energy from Drag
