B-Killers

Biography

B-Killers are a set of mechanical antagonists created by the villain Hellbeyd to battle Gingka Hagane and his friends within the Metal Fusion Battle Fortress video game, tasked with gathering combat data on the bladers trapped inside the fortress. They mirror the Beyblades of the game's various trapped bladers when appearing individually, but universally wield Devil Serpenter when fighting as a group. The line escalates through three color-coded forms — yellow Basic, blue Super, and purple Ultra — with the Ultra Form appearing only once in the entire game.
