The "Battlegrid War" was a large-scale conflict involving the various Megazords of the different universes against a threat known as "The Calamity". At the brink of defeat, MegaSword appeared, and the Megazords offered their powers, creating the "Power Rings", which destroyed the Calamity but also provoked the destruction and recreation of the universe with the rings scattered across the cosmos. Sometime later, five outcasts from society are given the chance to change their lives when MegaSword chooses them to transform into the Primal Thunder Rangers, who are tasked with gathering the Power Rings and the one who assembles all of them will get their wish granted, which starts a competition not only between the group, but against the Void World, as well other people that have been chosen also to get their wish granted dubbed the "Power Rangers".
