Dalek Prime

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.

Becoming the Emperor
Genetic variant Two-One-Zero was sent to pass an ordeal. On the planet Shade, he had to collaborate with Steven Taylor to survive Chaons who controlled the planet and to get to a transmat station to escape. Several times Steven saved Two-One-Zero from death, once taking it out of the casing and carrying in his hands wrapped in a tarpaulin. During the whole ordeal, Two-One-Zero exhibited qualities unusual for Daleks: he tried to save human prisoners' lives and exterminated another Dalek to save Steven's life. He promised to give Steven a transmat code to return back to the First Doctor and Vicki on the planet Entropica, but betrayed Steven in the very end, giving him transmat coordinates that would lead him to certain death.

Upon returning to Skaro, Two-One-Zero demonstrated that it was indeed a superior Dalek as he was the only one to return from the ordeal. He was transferred to a new casing and became the Emperor of Daleks. His experience with Steven prompted him to search for the Human factor as a way to achieve total Dalek domination. (AUDIO: Across the Darkened City)

Search for the Human factor
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. (TV: The Evil of the Daleks, PROSE: The Evil of the Daleks)

The Emperor survived when his forces began rebuilding, resulting in the emergence of a new command structure involving grey Dalek drones and Gold Supreme Daleks. (TV: Day of the Daleks)

Shortly after this, the Emperor met Bernice Summerfield, who the Emperor questioned on why the Civil War had occurred. (AUDIO: The Lights of Skaro)
