Such formidable villains as Shriek, Inque, the Jokerz and the Royal Flush gang continue to make like difficult for the "new" Batman, a.k.a. Terry McGinniss, as he tries to purge crime from the Gotham City of A.D. 2021 in Season Three of the animated Batman Beyond. Adding to Terry's burden this season is an old friend who has switched over to the dark side and reemerged as criminal genius "Big Time" Bigelow; and then there's that "invulnerable" supervillain whom even Batman cannot defeat despite a veritable arsenal of high-tech crimebusting hardware. As for "original" Batman Bruce Wayne, he is not as embittered and isolated as in seasons past, though he still yearns for the days of his idealistic youth, so much so that he agrees to undergo an experiment that will shave several years off his age--an experiment which, unfortunately, carries a heavy price tag. Episode highlights during the third season include the two-part "The Call," a crossover with the like-vintage superhero cartoon series Justice League of America, with guest appearances by Superman, Aquagirl, the Green Lantern, and Warhawk--one of whom will, to universal horror, emerge as the villain of the piece. And in another two-parter, Terry/Batman goes mano a mano with a particularly vicious ninja gang known as Kobra.
