Plot
Continuing the adventures of the Justice League, this incarnation of the show replaced Marvin, Wendy, and Wonder Dog with the Wonder Twins. Zan and Jayna, from the planet Exor, possessed shape shifting powers; Zan could become any form of water or ice, while Jayna could assume the shape of any animal. Assisted by their pet monkey Gleek, they not only helped the Justice Leaguers but lent assistance to teenagers in trouble. In addition to the classic Superman/Batman/Robin/Aquaman/Wonder Woman lineup, guests such as the Flash, the Atom, Green Lantern, and Hawkman & Hawkwoman appeared occasionally.
