Ellis (The Sontarans)

Ellis was a member of the Space Security Service. He was part of the platoon with captured the First Doctor and Steven Taylor. Shortly afterwards he had to fight a squadron of Sontarans. He was the first person to climb into a tunnel through the planet. He was a good shot, which helped when they were escaping the Sontarans. He had the only map of the tunnels in the asteroid. He was killed detonating a grenade. (AUDIO: The Sontarans)
