The Magma Cammander is one of Dr. Inferno's henchmen. He is quite possibly a cyborg, and has a jaw like Break Jaw's. He is highly intelligent, and has created Magma Drones to serve him. He might even be a robot, as he dosen't have any flesh showing.

He opperates from a hidden base outside Lego City, from which he controls his robotic servants. He and his Magma Drones appear in set 8971 Aerial Defense Unit.
