Dalek saucer commander (The Dalek Invasion of Earth)

A Dalek saucer commander was the designated commander of the Dalek flying saucer during the 22nd century Dalek invasion of Earth.

In Bedfordshire, the First Doctor encountered the 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 base unit. 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.

Prop
The prop for the saucer commander is the same prop for the Supreme Controller, one of the four originally constructed for use in The Daleks. The production team didn't paint it in time for the show as seen during the attack on the saucer — the Commander went in but the Supreme came out — for it was not seen during the second part of part 2 and the rest of the episode.

Colour scheme
The colour scheme used for the saucer commander has not reappeared in any subsequent televised episodes to date. However, the "Dalek Patrol Ship" sets released in 2014 included an exclusive 3.75-inch bronze "Dalek pilot" figurine bearing a black dome and alternating black "skirt" panels identical to the colour scheme of the saucer commander.

Theatrical adaptation
In the remake of The Dalek Invasion of Earth starring Peter Cushing, the saucer commander's role is taken up by the Red Dalek.
