Zeel
Zeel was a Sontaran Captain of the Twenty-First Sontaran Battle Fleet. He boasted that his men were some of the most cunning and well trained in the galaxy, and that they were eager to draw blood.
He was on Mars when he confronted the Doctors and their companions, ordering their immediate surrender only to be defeated by them. Asserting the Time Lords' Laws of Time, the Eleventh Doctor pleaded with Zeel to allow his company to stabilise time, warning the Sontarans that their interference in the timeline could erase their own Empire from history. Zeel was not disuaded, confident that a million more Sontarans would replace him were he to be erased from history. (GAME: "The Sontaran Threat")
