Actor:

Bob Kreesus was a gambler who believed that an alien machine he had won was bringing him luck by extracting the good fortune of the Triskaidekaphobes, which he kept on the moon below him while he lived a life of luxury on board his ship, which was disguised as a rain cloud. When he was teleported down to the moon's surface by the Doctor, who had destroyed his machine, he accidently slipped on a banana skin and fell over a cliff edge. (DWAM: Triskaidekaphobia)
