Skree

Lieutenant Skree of the Tenth Sontaran Battle Fleet was the operations officer on board General Staal's Sontaran Warship in 2009, during its attempt turn Earth into a Sontaran cloning planet. He was identical in appearance to his superior Commander Skorr. Following Skorr's death, Skree manned his station while open-skinned. He was killed, along with the other Sontarans on the flagship, when Luke Rattigan activated his atmospheric converter on board, destroying it. (TV: The Sontaran Stratagem/The Poison Sky)
