Action Family FOX Kids Science Fiction Superheroes

Tales of teens who morph into super-powered heroes have, in turn, morphed into a powerful franchise that includes a merchandising cornucopia, a feature film and various TV permutations, including 'Power Rangers Zeo,' 'Power Rangers Turbo' and 'Power Rangers DinoThunder.' Inspired by Japanese television (with sequences from 'Zyu Rangers'), it uses campy humor, martial arts and violent drama---so violent at times, in fact, that it has spurred complaints from child-development experts.
