Prepare for a battle of the ages when the Justice League faces off towards its archenemies, the Legion of Doom, in an all-new film from DC Comics. A mysterious being generally known as the Time Trapper arises, and a sinister plan led by Lex Luthor sends the Legion of Doom again in time to get rid of Superman, Surprise Lady and Batman earlier than they turn into tremendous heroes. For Aquaman, Flash and Cyborg, together with teen tremendous heroes Karate Child and Dawnstar, the stakes have by no means been increased, the rescue mission by no means deadlier. So be part of the battle for the long run because the Justice League confronts its final problem… the specter of having by no means existed!
