Cybernaut Zogron was a Cyber-Leader who commanded a mighty Cyber-Fleet that crashed on the remote planet AS4.

A reactivated Cyberman kidnapped Jetsam and took him in the Doctor's TARDIS to reactivate Zogron so that he may once again "rule time and space." Like other Cybermen, Jetsam had reprogrammed Zogron as a butler and he infuriated the Cyberman by offering him a before-dinner sherry. Tracked by the Fourth Doctor, Flotsam and Dutch on the Drifter, they landed on AS4 and Dutch destroyed the Cyberman by coating it in quick-setting polymer paint. Zogron presumably remained programmed as a butler. (COMIC: Junk-Yard Demon)
