Male guard (The Impossible Planet)

From Tardis Wiki, the free Doctor Who reference

A male guard was a member of the Walker Expedition on Sanctuary Base 6 in the 43rd century. He worked in Ood Habitation with Danny Bartock as a guard during the expedition down to the power source. The Ood were possessed by the Beast. As the Ood became unmanageable the guard considered shooting them down as one had left its place, but only just pointing his gun from a far distance, the Ood's translator ball was flung to his forehead, electrocuting and killing him.
