Gazille is the Dragon Slayer of Iron, meaning that he has the powers of a dragon and is strong enough to fight evenly with a dragon. He was taught how to fight, how to live in the wilderness and how to use language, as well as how to use his famous Iron Dragon Slayer Magic, by the Dragon of Iron, Metalicana. Gazille has been searching for Metalicana since he disappeared along with the other dragons in the Galaxy roughly seventy years ago.
