The Drone is an enemy of Space Ghost in the original Hannah-Barbera series.
A mysterious black spaceship evades the alarms and emits a solitary figure, who burns his way into the Ghost Headquarter and leaves a strange device in the Phantom Cruiser. After he leaves, the device comes on. It's a drone - a robot that pilots the Phantom Cruiser, smashing it through the door and taking to the Black Planet! Space Ghost must follow it, and when he gets there, he must fight his own drone piloted Phantom Cruiser as it tries to kill him!
