Justice League Adventures – Trapped in Time (Family/Action)

In the present day, Lex Luthor and his Legion of Doom try to use cryogenic rays from orbital satellites to expand the Earth’s polar ice caps, reducing sea levels and creating new islands they intend to rule. Superman and the Justice League confront the Legion, ultimately destroying the satellites. Refusing to accept defeat, Captain Cold overloads the remaining satellite, which falls to Earth and freezes Luthor, who is believed dead.

In the future of the 31st century, teenage superheroes-in-training Dawnstar and Karate Kid are visiting a museum dedicated to the League’s exploits. They accidentally release Luthor, who has been in suspended animation for nearly a millennium following his battle with the League, and was relocated to the museum after being discovered and excavated in the 29th century. Luthor explores the museum, discovers Superman’s secret identity and locates an ancient item called the Eternity Glass, which can manipulate time and space. Taking Captain Cold’s weapon, he freezes Dawnstar and Karate Kid. He then uses the Eternity Glass to release Time Trapper as his servant, allowing him to travel to the point when he last fought the League. The young heroes break free and follow.
