Phijax IV was a planet known for its constant rain, light gravity and high quality All-Night Steak Restaurants.
Though originally a peaceful place, Phijax IV was taken over by the Glutonoid, who forced warriors to fight for his amusement and food. The Tenth Doctor later tried to bring Rose to try one of the steak restaurants, but arrived after the Glutonoid had taken over. They were chained together and forced to fight the champion, which they did by relying on the lighter gravity. When they won, the Glutonoid tried to eat Rose anyway, but the Doctor saved her by feeding the Glutonoid a fatal mixture of the TARDIS' food pills. (COMIC: The Glutonoid Menace)
