A Dalek Emperor ruled the Dalek Empire on Skaro. This Emperor remained in an enormous, immobile, conical shell plugged into a corner of the control room in the Dalek City on Skaro. It was connected to the wall by tubes, and spoke in an echoing voice.
This Emperor tried to win the wars by blackmailing the Second Doctor. He ordered the Daleks to capture the Doctor so that they could force him to conduct research into the Human Factor. This would unlock the secrets of the Dalek Factor which was to be spread throughout all areas of human history, giving all humans the mentality of a Dalek and preventing the Great War from ever happening. He was seemingly destroyed by a civil war between humanised Daleks and un-altered Daleks. However, a light was seen blinking on its casing at the end, indicating some kind of activity.
