Steam Punk is a Fire element Skylander introduced in Skylanders: Ancient Elements. He is one of the Elemental Guardians, and has Steel as his Ancient Element.
Steam Punk was the last of his kind of people made out of pure fire that existed in Skylands for many centuries. As time went on, these flames eventually died out, and soon the race would go extinct. Knowing his time was near, Steam Punk ventured across Skylands searching for a new body, a search that lead him to an old scrapyard. There he found what appeared to be half stove and half battle armor. But he didn't have time to consider as he was just about to be snuffed out, so he inhabited the body and got used to it very quickly, though discovered his control over fire wasn't as strong as it used to be, only coming out as steam. Regardless, he was determined to live on the legacy of his extinguished people.
