Goku looked at his small hands and then up at Uub. The training was over, but a new, more dangerous journey had just begun.

The air atop Lookout was thin, but for Uub, it felt heavy with the legacy of the man standing across from him. Five years had passed since the young boy from the village had entered the World Martial Arts Tournament, and five years had passed since Goku had whisked him away to the heavens to unlock his dormant power.

Inside the ancient halls of the Lookout, a shadow moved. Emperor Pilaf, older but no wiser, had finally breached the inner sanctum where the Black Star Dragon Balls were kept—relics forgotten by time and guarded by the late Kami.

Before Uub could answer, a pillar of crimson light erupted from the temple. The sky didn't turn black as it did with Shenron; it turned a bruised, electric purple. The Earth began to tremble, not from a physical blow, but from a cosmic imbalance.

As the smoke cleared, the legendary warrior stood not as the titan who defeated Majin Buu, but as a child once more. The Black Star Dragon Balls scattered to the farthest reaches of the galaxy, and a countdown began that would threaten the very existence of the planet.

Goku wiped sweat from his brow, his orange gi tattered but his grin as wide as ever. "You’ve grown, Uub. Your control over that energy... it’s unlike anything I’ve seen since, well, since I fought Buu."
