Zogron

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