In the conclusion of Justice League Unlimited's two-part season-three finale, JL members Batman, Green Lantern, and Wonder Woman continue their pursuit of time-traveling thief David Clinton. Chasing their quarry to his own time -- 50 years in the future -- the three Leaguers come face to face with their own furturistic counterparts, Batman II, Static, and War Hawk. The six superheroes pool their resources to do battle against the vicious "Jokerz" gang, only to find a greater menace in the form of David Clinton -- who, hoping to get even with those who have mocked his skills as an inventor, has transformed himself into Lord Chronos, all-powerful (and highly dangerous) Master of Space and Time. ~ Rovi
