Brak was one of Space ghost's greatest villains, and much later, one of his companions.
During his adolescence, Brak lived with his parents and attended the Learnmore High School, along with Zorak. Zorak often got Brak into trouble, such as the time when he encouraged Brak to kidnap Mr. Bawk Ba Gawk, the school's mascot. (The Brak Show: "Mr. Bawk Ba Gawk")
Brak once stated that his planet is Polynesian.
