In 2000, the Justice League reunited once again in a two-part episode of Batman Beyond titled The Call.
One catch, because the series was set in the future, your typical Leaguers couldn't be used. This incarnation, dubbed the Justice League Unlimited consisted of Superman, Micron ( a flying Atom type), Big Barda (one of the New Gods), Warhawk (Hawkman with metal wings), a Green Lantern kid, and Aquagirl (daughter of Aquaman). Through the course of the episode, Batman joins the League.
These episodes served as a test run for a Justice League series which later came into being. Member of this future League joined by Static Shock would reappear as guest stars in the Justice League Unlimited series episode The Once and Future Thing: Time Warped.
