Command Dalek (Into the Dalek)

A bronze Command Dalek commanded a Dalek saucer which pursued the Aristotle during the Good Dalek Incident. When the Aristotle was discovered, it ordered a force of boarding Daleks dispatched. The saucer eventually received a signal to retreat from the Aristotle, indicating that the ship had self-destructed; this message was in fact a deception from the "Good Dalek", who had repelled the boarders.

After returning to the command saucer, Rusty managed to destroy it, being left adrift in its wreckage. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)
