Dalek leader (The Chase)

A Dalek leader assumed command of the assassination squad sent to hunt down the First Doctor in a Dalek time machine, though they acted under the instructions of the Black Dalek and the Dalek Prime. The Dalek leader was the final surviving Dalek during the battle with the Mechanoids on Mechanus. In a last bid to kill the Doctor, the Dalek leader set the Mechanoid City to self-destruct, killing everything inside, but the Doctor ultimately escaped. (PROSE: The Chase)
