Shazam! and The New Adventures of Batman, which prevented the use of characters such as Mister Atom, King Kull, Beautia Sivana, The Joker, The Penguin, Mr. Freeze, and Catwoman. Early conceptual art drawn by Alex Toth also included Heat Wave, Poison Ivy, and Abra Kadabra. Narration, music and character designs Bill Woodson provides the uncredited voice of the narrator in Challenge of the Superfriends, and the opening narration was by Stanley Jones. The show's main theme and original music was composed and arranged by musical director Hoyt Curtin. The music supervisor was Paul DeKorte. Character designs for this particular Super Friends series were done by Andre LeBlanc. Team composition experimentation 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). Lineups Superfriends/Justice League of America Eleven heroes make up the Superfriends/Justice League of America. They are: Legion of Doom Thirteen villains comprise the Legion of Doom during the Challenge of the Superfriends series. They are: Despite the claim in the program's title sequence that the Legion's members hail from "remote galaxies", only Brainiac and Sinestro are extraterrestrials; the remaining members are all natives of Earth (even though Bizarro called the Bizarro World home, he was created by Lex Luthor via a duplicator ray on Earth, technically making him a 'native' of Earth). Solomon Grundy is a zombie, an animated dead person, as the episode Monolith of Evil makes clear. In "History of Doom", even Solomon Grundy supposedly dies from the solar flare.
