Dragon Ball Z

Synopsis

The Supreme Kai brings himself, Dende and Old Kai back to the planet of the Kais. Dende heals Vegeta and Goku for the final time. Hercule finds the still body of Fat Buu, and asks Dende to heal him so that he won't die. Vegeta objects, and tells Hercule to move aside so he can destroy him. Vegeta says it is too dangerous for any form of Majin Buu to survive, but Hercule continues to plead with him. Goku takes Hercule's side, explaining to Vegeta that it was Fat Buu who saved Vegeta's life right before Goku threw the Spirit Bomb. Vegeta reluctantly agrees, and the Fat Majin Buu is healed. Supreme Kai takes them all back to Dende's lookout, where they reunite with friends and family. Goku tells his family that Old Kai gave him his life, so he can stay on earth for good as Chi-Chi breaks down in tears and hugs Goku. Six months later, they use their remaining wish with Shenron, asking him to erase the memory of Majin Buu from the mind of everyone on earth, so that the good Buu can assimilate into society. Life finally returns to normal on earth.
