Black Dalek Leader
A Supreme Dalek was a Black Dalek and the leader of the Renegade Daleks that opposed the Imperial Daleks commanded by Davros, now calling himself the Dalek Emperor. It formed an alliance with The Association led by George Ratcliffe to obtain the Hand of Omega. The Dalek Supreme ended up as the last surviving member of the original, Kaled-descended Daleks during the Shoreditch Incident. The Seventh Doctor convinced it that it had no purpose. At this point, in a state of confusion and distress, it destroyed itself, breaking the link with Judith Winters. (TV: Remembrance of the Daleks)
