When heroes alone are not enough... the world needs legends. Time-traveling rogue Rip Hunter assembled a disparate group of both heroes and villains - including Firestorm, the Atom, White Canary, Hawkgirl, Captain Cold, and Heatwave - to confront an unstoppable threat. After saving the world, the Legends of Tomorrow now are charged with protecting time itself -- the past, present, and future. This responsibility will take them across history, bringing them up against a threat unlike humanity has ever known.
