Styre

Styre was a Sontaran Field Major who experimented on captured human colonists on Earth to discover mankind's ability to resist a Sontaran invasion. He was defeated by the Doctor, Sarah Jane Smith, and Harry Sullivan. Styre died after connecting his probic vent to his ship. Harry having sabotaged the ship, rather than absorbing energy from the ship via his probic vent, the ship drained Styre's energy. (DW: The Sontaran Experiment)


 * As Sarah Jane noted, Styre appeared identical to Linx in most ways. However, unlike most Sontarans, Styre had five rather than three fingers on each hand.
