Rukh

Director Rukh was in charge of a castle of scientists on Sylvaniar. When the Sixth Doctor and Captain Krogh went to see him, they found him being attacked by a Cyberman. (COMIC: Revelation!, Genesis!)

Behind the scenes

 * As an in-joke, artist John Ridgway drew himself as Director Rukh being strangled by a Cyberman in the closing frame of Revelation!.
