Zogron

Zogron was a Cyber-Leader who was reprogammed as a butler by galactic scrap merchants. He was left in his command ship with the wreaked Cyber-Fleet on the remote planet AS4. A Cyberman sent the Doctor's TARDIS there and ordered Jetsam to reactivate Zogron. Zogron infuriated the Cyberman by offering him a before-dinner sherry. The TARDIS was being tracked by the Fourth Doctor, Flotsam and Dutch on the Drifter. They landed landed nearby and Dutch destroyed the Cyberman by coating it in quick-setting polymer paint.
