In Dino Charge, the Energems were given to a dozen dinosaurs for safe keeping by an alien, but they were lost when asteroids hit the Earth and wiped out the dinos. Now in the present day, an intergalactic bounty hunter starts sniffing around Earth looking for the Energems in order to harness their power and annihilate the world, so a team of Power Rangers forms to find the Energems first and fight the bounty hunter and other threats with dino-powered swords, blasters, Zords and Megazords.
