Bob is one of five alien fugitives who defected from their world's military when they realized that they had lost the war against the Goa'uld. He is introduced in the episode, 4.11 "Point of No Return" and was one of the aliens holding Sam Carter and Daniel Jackson against their will.
Later he posed as a production assistant at the television studies where Wormhole X-Treme was filmed, using the pseudonym “Steve Austin”. When he and his comrades discovered SG-1 was again following them, he acted as a decoy, leading Sam Carter and Daniel Jackson to the NID who were also trying to track the aliens. He and two of his comrades decided that they could no longer hide on Earth, recalling their spacecraft and leaving in the episode, 5.12 "Wormhole X-Treme".
