Major Varl was a Sontaran officer of the Ninth Sontaran Battle Group.
Under the command of his superior, Stike, he and a large group of Sontarans attacked Space Station Camera and killed nearly all aboard. Only Varl and Stike went with their new ally Chessene of the Franzine Grig to Spain. There Varl and Stike waited while Dastari attempted to find a way for them to possess time travel. Chessene betrayed them and attacked them with coronic acid; Varl died. Stike survived, but his wounds were catastrophic, and he died in the explosion of his ship. (TV: The Two Doctors)
