Emperor Dalek (City of the Daleks)

A new Emperor Dalek was installed in Kaalann by the Supreme Council of the New Dalek Paradigm after they acquired the Eye of Time, to act as their ruler after they restored Skaro. He had the blue-grey casing of a Strategist Dalek. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe)

He was surrounded by Strategist Daleks. When the Eleventh Doctor and Amy Pond travelled back in time to when Skaro was devastated and before the new Daleks arrived with the Eye of Time, they erased the Daleks' alterations and Kaalann was left abandoned. The new Emperor was never created as a result. (GAME: City of the Daleks)
