Upon entering its third season, the animated series Justice League serves up quite a few changes in its format. For starters, the titular League, comprised of the Earth's mightiest superheroes, is now under the full control of J'onn J'onnz, aka the Martian Manhunter, with former leaders Superman and Batman taking rather than issuing orders. For another, the League has been given a brand-new headquarters in an orbiting Earth satellite. Finally and most significantly, the series' title has been changed to Justice League Unlimited, reflecting the sudden expansion of the League's membership roster. In addition to old favorites J'onn J'onnz, Superman, Batman, Wonder Woman, the Flash, the Green Lantern, and Hawkgirl, the League has welcomed such newcomers as the Green Arrow, Supergirl, and Captain Atom along with a few "stringers" whom J'onn J'onnz occasionally calls upon for backup, utilizing their unique crime-fighting talents to the utmost. Foremost among the big story developments during season three include the reformation of former villain Lex Luthor, an effort by wicked sorcerer Mordred to banish all adults from the Earth (forcing several League members to transform into eight-year-olds!), the arrival of a new superhero team called the Ultimen, the resurrection of Batman's supposedly deceased perennial foe Solomon Grundy, and a time-warp journey to the Old West on one end of the spectrum and to a futuristic Gotham City at the other end. It is, in fact, this last-named adventure, the two-part "The Once and Future Thing," which brings the third season of Justice League (or is it, technically, the first season of Justice League Unlimited?) to a pulse-pounding conclusion. ~ Rovi
