Superman/Batman: Apocalypse

An adaptation of Mark Waid's "Tower of Babel" story from the JLA comic. Vandal Savage steals confidential files Batman has compiled on the members of the Justice League, and learns all their weaknesses.

A heroic version of Lex Luthor from an alternate universe appears to recruit the Justice League to help save his Earth from the Crime Syndicate, an evil version of the League. What ensues is the ultimate battle of good versus evil in a war that threatens both planets and, through a devious plan launched by Batman's counterpart Owlman, puts the balance of all existence in peril.

Gotham City is under siege by a series of bizarre crimes and only the world's greatest detective, Batman, can unravel the mystery! The trail leads to none other than the Penguin and his Animilitia, an animal-inspired squad of villains including Silverback, Cheetah, Killer Croc and the monstrous Man-Bat.

Mr. Freeze turns Killer Croc and Bane into super-sized monsters, and they bash their way through downtown Gotham until the Caped Crusader and his team of heroes join the fight in their giant robot mechs.
