Dragon Ball Kai

Kid Buu is blasted apart by the explosion, but he reforms after the destruction of the Earth, and goes on a rampage throughout the galaxy. He goes from planet to planet, looking for Goku and Vegeta, and then destroys each planet when he doesn't find them. He goes to the Grand Kai's planet, and starts to toy with everyone there. When he becomes bored, he creates an energy ball, intending to destroy the Grand Kai's planet. Supreme Kai offers Goku and Vegeta his fusion earrings, but they both refuse them. They raise their power levels so Buu will know where to find them. Buu abandons his attempt to destroy the Grand Kai's planet and teleports to the world of the Kais. The Supreme Kai transports himself, Dende, and Old Kai to a distant planet so they will be out of Goku and Vegeta's way, along with a crystal ball that allows them to watch the battle. Unfortunately, they forget to take Hercule 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 Buu. Goku 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 shock waves rock the entire planet, disfiguring its shape and leaving the surface ragged and uneven. Goku decides to power up to Super Saiyan 3.
