The Magma Drones are robots controlled and built by the Magma Commander.
They feature the special Agents robot arm on the end of which is a laser (an amber-coloured cone). Their "heads" consist of a black antenna/lever piece. They are controlled via the large satellite dish mounted on top of Magma Commander's base. The mission of the Agents in the Aerial Defence Unit was to destroy the satellite and shut the Magma Drones down. They were once used to siege LEGO City, but it is unknown if this plan succeeded.
