From Pan, Uub discovers that his friend and teacher, Goku has been “killed” by Baby, and he vows to avenge him. Uub and Baby begin to fight, and Uub seems to be winning. Gohan, Goten, and Trunks come to Baby’s aid, but he reveals that he was just testing Uub. Frustrated by his three servants’ interference, he apparently kills them. Meanwhile, Goku sees what’s happening on the Tuffle planet and demands to be sent there immediately. The Elder Kai begins to understand what Goku has said and decides to send Goku there without completing the training, but then reveals that the purpose of Goku’s training was to grow his tail so he could have enough energy to defeat Baby, but because there is no time to waste, he decides to pull it out manually, using Sugoro’s son as a giant pair of pliers. On Baby’s Tuffle Planet, the parasite tyrant in Vegeta’s body quickly overpowers Uub, and begins to gather a giant energy ball, just like the one he used to attack Goku. Buu takes Pan and Mr. Satan to safety. He says goodbye to them, and then flies back and absorbs the blast. Buu explodes, and the pieces of him rain down on Uub. After recalling their past of once being in one body, Buu and Uub fuse to form Majuub.
