Dragon Ball Z

Synopsis

Babidi tells the earth that anyone with any information about Piccolo, Goten, or Trunks should tell him. To stop any further damage, Piccolo wants to turn himself in, but Goku convinces him not to, because he knows that even if the three turn themselves it, it won't stop Buu's destruction. Goten and Trunks wake up, and they learn about Vegeta and Gohan's (supposed) demise. Goku is harsh with them, because they can't waste any time mourning right now. The boys, although angry at Goku for not saving Gohan and Vegeta, know that they must be tough to stop Majin Buu. In the world of the Kais, Kibito heals Gohan, and the Supreme Kai tells him about the Z Sword. It is a mystical sword that contains great power, and even the Kais themselves could not pull it from the rock it is now stuck in. The Supreme Kai believes that Gohan possesses the strength to do so.
