Twenty years ago, in a magic-filled dimension parallel world, the forces of darkness came into power and a war called the “Great Battle” between good and evil began, unbeknownst to the citizens of the human world. An army of the monsters, led by a powerful warrior named Tirek, swarmed into the land with their sights set on taking over the magical realm, the human realm and possibly the universe. In the midst, they combat five wizards, who pushed back against the dark forces. The strongest wizard of all, Solaris, cast a spell and sent the evil warriors into the Tartarus, having the Gatekeeper seal the gates for all eternity. The forces of good successfully thwarted the dark forces’ attempt to take the surface world, but they lost the five wizards, including Solaris, who sealed himself on their side of the Gate to make sure the evil forces did not escape.

In the present day, the city of Canterlot was struck by an earthquake, which was just enough to crack the seal, allowing evil to renew its attempt to invade the earth. The sorceress Celestia realizing that the forces of evil had returned, sought out the warriors of legend, five teens living in Canterlot, to become the Power Rangers alongside her.
