Skorr

Skorr the Bloodbringer served under General Staal during the Tenth Sontaran Battle Fleet's invasion of Earth in 2009.

Biography
Though subservient to Staal, Skorr had great respect for him, even going so far as requesting to remove his own helmet so that, like his General, he could face battle "open skinned." After this he went to oversee the creation of a Martha Jones clone to infiltrate UNIT.(DW: The Sontaran Stratagem)

After ATMOS was activated, Skorr prepared an Attack Squad before ambushing The UNIT soldiers in the ATMOS Base, and jested that they were winning too easily, declaring, "this isn’t war, this is SPORT!"

When UNIT fought back, Skorr once again fronted the defence, killing many soldiers. He ultimately fell when Colonel Mace shot him twice with a pistol. Skorr muttered "wonderful" as he succumbed to his injuries; knowing he had died a good death for a soldier, and the irony in being defeated facing his enemy - who was the very primitive race that he had just mocked previously.
