A prisoner of the Cybermen, forced to work on the surface of their planet Telos. He had been partially converted into a Cyberman, given mechanical limbs. He formed a plan of escape with fellow captive Stratton. They would kill a guard and use its head as a disguise in order to infiltrate Cyber-Control as prisoner and escort. There, they would steal the Cybermen's captured time-ship. This needed three pilots. The mercenary Lytton would be the third of the crew, in an elaborate plan hatched by the Cryons, Telos' native species. The Cyber-Controller had anticipated this plot, and Bates was killed by a booby-trapped door just as he entered the base.
