Gravity Drones are drones based on Ancient X-nelian Technology designed to patrol specific areas. Gravity Drones are capable of sustaining flight by an anti-gravitational device stored in it's body. These drones shoot short-range laser blasts at their targets. They were considered to be the highest of security drones before the X-nelian Revolution Period. Gravity Drones are very weak and can be easily destroyed by any conventional weapons. The Ancient Temple is the only known place where Gravity Drones are present still functioning.
