A Vulcan security officer sent into the desert by Administrator V'Las in 2154 to stop Archer, T'Pol and T'Pau from carrying the Kir'Shara to the capital.
Talok appears in the fourth-season Enterprise episode Kir'Shara, played by Todd Stashwick. He leads a squad of commandos into the Forge after the bombardment of the Syrrannite sanctuary, with orders to finish off the survivors.
His men capture T'Pol, whom he questions about the route her companions have taken. She tries to mislead him, but Talok is shrewd enough to guess where they are really heading and continues the pursuit.
He catches up with Archer and T'Pau among the rocks. Archer, who carries the katra of Surak and with it a knowledge of Vulcan fighting skills, overcomes Talok and his soldiers, and the artefact reaches the High Command.
