His powers are heavily focused on his molten rock Buster. His pyrokinesis is channeled through the buster, allowing him to shoot fireballs, streams of fire, and create a sword made of fire. He has not been seen using any of his powers without it yet. By pressing the buster into the ground, he can channel heat through it, creating a Fire Tower.
