Goku throws a giant boulder at Gohan to test his abilities with the Z Sword. Gohan makes a clean cut, so the Supreme Kai conjures up a block of the hardest metal in the universe called 'Katchin'. This time, the sword can't cut it, and breaks under the pressure. But from out of the Z Sword comes Old Kai, who is fifteen generations older than Supreme Kai. In exchange for a date with Bulma, Old Kai agrees to awaken Gohan's sleeping powers. He starts to do a strange dance in circles around the Saiyan, and says that it will take 5 hours to awaken his sleeping power. Meanwhile, Goten and Trunks have finally mastered the Fusion Dance, and are ready to attempt it for real.
