One day, Goku was training in the forest when the Dragon Radar started going haywire—yet there were no Dragon Balls nearby. Suddenly, a strange glowing scale appeared in front of him. Curious, Goku picked it up, and in an instant, he was pulled into a swirling portal.

When he landed, he found himself in a colorful world unlike anything he’d seen before. Huge rolling hills, rainbow-colored skies, and dragons of all shapes and sizes filled the land.
