The Energems are metallic and mineral crystals of various colors that channel untold powers of the universe. As described by their own guardian, their power is unfathomable, transcending the normal governing principles of the cosmos and beyond, such as space, time, good and evil. During prehistoric times, Keeper crashed on Earth with ten of the Energems in tow while on the run from the ruthless bounty hunter Sledge. To keep the Energems safe, Keeper entrusted them to ten of the world's bravest dinosaurs, bonding the objects with their animal spirits. Unfortunately, their whereabouts were lost when a subsequent rain of asteroids led to the extinction of the dinosaurs. They were sought out by the villainous forces of Sledge, Lord Arcanon, Snide and Heckyl, as well as the heroic Dino Charge Power Rangers. The existence of an eleventh Energem, the Dark Energem, was confirmed by Keeper and his pupil and apprentice Zenowing. The Dark Energem is capable of neutralizing the powers of the other Energems and also keeps the others' ultimate power from being used - the power to open portals througout time.
