A Final Showdown at the Summit! Face-Off in the World of the Kais!.After being blasted apart by Earth's destruction, Kid Buu reforms his body. Kid Buu goes on a rampage throughout the galaxy in search for Goku and Vegeta. He destroys every planet he does not find them on. He goes to the Grand Kai's planet and starts to toy with everyone there. When he becomes bored, he creates an energy ball that is intended to destroy the Grand Kai's planet. After the two Saiyans turn down the offer to use Kaibito's Potara earrings to reform into Vegito, Goku and Vegeta raise their power levels to get Kid Buu's attention. After sensing their energy, Kid Buu abandons his attempt to destroy the Grand Kai's planet. Kid Buu teleports himself to the Sacred World of the Kais. As Kid Buu arrives, Kaibito transports himself, Dende, and Old Kai to a distant planet so they will be out of Goku and Vegeta's way. Kaibito takes the crystal ball that allows them to watch the battle. They forget to take Mr. Satan and Bee along. Goku and Vegeta play rock, paper, scissors to decide who will fight first, and Goku wins. He powers up to Super Saiyan 2 and starts beating up Kid Buu. Goku blasts him apart, but he reforms. Kid Buu creates another massive energy ball and throws it down at the planet. Goku is able to deflect it, but Kid Buu guides the ball back around and into the planet. Powerful shock waves rock the entire planet and disfigures its shape, which leaves the surface ragged and uneven.
