La menace qui pèse sur l’autre-monde

The Supreme Kai transports himself, Dende, and the Elder Kai to a distant planet so they will be out of Goku and Vegeta's way. Unfortunately, they forget to take Hercule and Bee along. Goku and Vegeta play janken to decide who will fight first, and Goku wins. He powers up, and starts beating on Buu. He blasts him apart, but he reforms. Buu creates another massive energy ball and throws it down at the planet. Goku is able to deflect it, but Buu guides the ball back around and into the planet. Powerful earthquakes rock the surface of the planet, leaving the ground ragged and uneven. Goku decides to power up to Super Saiyan 3.
