In Bedfordshire during the 22nd century Dalek invasion of Earth, the First Doctor encountered a saucer commander, which served as the second-in-command to the Supreme Dalek. Unlike Dalek drones, the Saucer Commander had a unique casing featuring a black dome and alternating black-and-silver panels on the lower half. The commander, along with the Supreme Dalek and the Dalek fleet, was destroyed at the climax of the invasion by the uprush from the exploding penetrative explosive capsule.
