If your talking about the Bahamut from the "Rage of Bahamut" series then its neither Dragon King class nor Heavenly Dragon class but Dragon God or True Dragon class. I'm saying this because like Trihexa it took all supernatural factions and the God Zeus and the Demon King Satan to seal themselves in order to defeat Bahamut. In fact depending on which series came first I'm thinking Ishibumi might have "borrowed" that plot line.
