In a world ruled by Quirks, Cain Oliver was born without one-but he was never meant to be ordinary. As the direct descendant of legendary Power Ranger Tommy Oliver, Cain carries a power unlike any this Quirk-filled society has seen. Once a bright-eyed, Quirkless kid and best friend to Mina Ashido, Cain mysteriously vanished from the world-only to reappear years later, transformed. Transported to a parallel reality known as No. 1's World, Cain was adopted by heroic warriors Tega Sword and Tega June, who trained him to inherit the mantle of the Power Rangers. Through ancient relics-the Morphing Rings and Ranger Rings-Cain now channels the strength, armor, and weapons of Rangers across the ages. Now back in his original world and enrolling at U.A. High, Cain faces a society that doubts the power of anyone without a Quirk. But the Morphing Grid, long hidden in this reality, is awakening-and not everyone is ready to accept its return. From the shadows, iconic villains once thought lost to time begin to rise: Lord Zedd. Divatox. Mesogog. Trakeena. Lothor. All reborn, evolved, and eager to seize this new era of heroes-and corrupt it for their own twisted purposes. Cain's return isn't just about proving himself. It's about defending both worlds from evil that spans dimensions-and making sure a legacy built on courage never fades. Because the spirit of a Ranger never dies. And Cain Oliver is ready to morph into legend.
