Description: Gorilla Grodd invents a time conveyor to allow anyone to travel through time. Black Manta and Giganta trap Aquaman and Apache Chief in 70,000,000 B.C and rob South Africa's diamond mines, Sinestro and Captain Cold trap Green Lantern and Samurai in 500 A.D and rob King Arthur while Grodd and Solomon Grundy trap Batman and Robin in Ancient Rome and rob Caesar, the emperor. The Legion of Doom learn a hard lesson in underestimating the Super Friends when they are foiled once more. The Legion of Doom uses Gorilla Grodd's inter-spatial time conveyor to steal history's greatest treasures and to trap six of the SuperFriends in the past. Grodd invents an Interspatial Time Conveyor which he intends to use to rob history of some of its greatest treasures. In attempts to stop the Legion, Aquaman and Apache Chief are trapped in Prehistoric times, Green Lantern and Samurai become stranded in King Arthur's Camelot and Batman and Robin are left behind in Ancient Rome. This all leads to a final confrontation at Sutter's Mill.
