Aku

 was an Egyptian slave who was present when the Daleks and the First Doctor arrived in Egypt. When the Daleks and the Doctor left, Aku was one of the survivors. A Dalek was also left behind, and when Aku touched it, it asked for orders. Aku proceeded to have the Daleks destroy his masters, and over time Aku became leader, destroying his people's enemies. When Aku was ready to die, he had the Dalek buried with him. (PROSE: The Eighth Wonder of the World)
