Dalek Supreme (The Genocide Machine)

A Dalek Supreme was part of the Kar-Charrat mission to obtain information from the planet's library.

It was the immediate subordinate of the Dalek Emperor. It has a Dalek Destroyer in orbit. The mission failed and the Emperor ordered the Dalek Supreme to place the Chief Scientist to take command of its mothership and self-destruct, which it did. (AUDIO: The Genocide Machine)
