Flash (Barry Allen)
Hanna-Barbera's writers experimented with team composition as well. "Challenge of the Superfriends" added The Flash (Barry Allen), Green Lantern (Hal Jordan), and Hawkman (Katar Hol) who were members of the Justice League of America, as well as several new characters: Black Vulcan (who was based on the DC Comics character Black Lightning), Apache Chief, and Samurai. These characters were created to add racial and cultural diversity to the show (this was also mentioned in some of the episode introduction extras on the first two "Challenge of the Super Friends" DVDs).
