Ocker was the chief of security at the Tok'ra base in the Risa System which was attacked by Anubis. He was killed by the Ashrak sent by Anubis to the Alpha Site, in the episode, 6.09 "Allegiance". His murder was blamed on a Rebel Jaffa named Artok, but while Artok was being held in confinement, the Ashrak killed him, too. These two individuals' murders sparked a large scale manhunt until the Ashrak was neutralized. It had been the intention that the alliances held among the Tok'ra, Rebel Jaffa, and Tau'ri would be threatened by the Ashrak's activities, but the opposite outcome occurred.
