Drenz
From Tardis Wiki, the free Doctor Who reference
Drenz was the final pacifist ruler of the humanoid Daleks. He demanded that War Minister Zolfian end his plans to wage war against the Thals, warning that they could destroy Skaro. Zolfian instead shot and killed him, declaring that Drenz was unfit to rule the Daleks. Drenz' predictions would soon prove true. (COMIC: Genesis of Evil)
Behind the scenes
Later accounts would claim this occurred in 2003 and that after this event Daleks abandoned personal names. (NOTVALID: The Dalek Dictionary)
