Millions of years ago, an intergalactic bounty hunter named Sledge tried desperately to capture the 10 mysterious Energems, each capable of filling whomever possessed them with incredible powers. Keeper, the wise and ancient guardian of the Energems, entrusted each Energem to the Earth's mightiest beasts, the dinosaurs, for protection. Centuries later after the dinosaurs went extinct, some of the Energems were discovered by humans. Those who proved worthy gained the ability to morph into Power Rangers. But now, Sledge has returned and has vowed to capture the Energems at all costs. It is up to the Power Rangers Dino Charge to hunt down the rest of the Energems and defeat Sledge once and for all!
