Saturn appeared in the episode "Battle of the Planets" when Zim and Dib raced through its rocky rings. Saturn also makes a brief appearance in the episode "The Frycook What Came from All That Space" when Zim is flying back to Earth after escaping Sizz-Lorr from the planet Foodcourtia.
Saturn would also have made a brief but important role in the series finale "Invader Dib" as it was supposedly where Dib and The Resisty would be banished to after attempting to either conquer or destroy the Irken Empire.
