Iron Monger

Iron Monger (アイアンモンガー): A volcano-themed Monger who was created from the Iron Ball, an orb made of super-strong heavy alloy that increases in size and weight when absorbing energy. Though the truck holding it is intercepted by Vulshark and Vulpanther, the Iron Ball manages to break out under Hedorian's control to be converted. Though he was created to oversee the super-heavy alloy factory, Iron Monger unintentionally reveals the factory's location when he goes after Misa as her kindness was the first energy he absorbed. Defeated by the Vulcan Ball, Iron Monger uses a mace staff in his giant form before being destroyed by Sun Vulcan Robo.
