Shogalath

Shogalath was a well known god in the star system of the Vandosion race. A group of rebelling Vandos aliens thought of Shogalath as an abomination, then discovered that he had died. Eventually it was found that Shogalath had been reincarnated as Phil Tyson. When the Vandosians tracked down Tyson, the Ninth Doctor saved him. Before Phil left, he whispered to the Doctor, "Bad Wolf." (DWAN: Mr Nobody)
