Batman Beyond: Return of the Joker

In latter-21st-century Gotham City, The Jokerz, a street gang enamored of the city's infamous Clown Prince Of Crime, is breaking into a high-tech engineering plant to steal a powerful generator, a crime stopped by the new Batman (Terry McGuiness) and which puzzles Terry and his mentor, the elderly original Batman Bruce Wayne. The reason for this and other "geek junk" thefts is a mystery even to The Jokerz gang, who are now working for someone claiming to be the original Joker himself. When he makes an appearence at a charity function attended by Bruce Wayne (cover to steal another generator), the Joker taunts Wayne, and later sends his minions to attack Terry McGuiness while he attacks the Batcave. But the original Joker died forty years earlier, and why does this new Joker want high-tech items? When a shaken Barbara Gordon explains the fate of the original Joker, Terry begins to piece the twin mysteries together, culimating in a confrontation with the Joker that literally threatens the very existence of Gotham City.
