Even having absorbed Gohan, Buu's strength was nowhere near comparable to Vegetto's, but he pretended to be at a disadvantage for the monster to absorb him and thus be able to rescue Gohan and the others. Inside Bu's body, the effect of the Potala earrings faded and Goku and Vegeta parted ways. After rescuing his companions, Vegeta discovered that the obese Buu was also locked in that body. Realizing that something was wrong inside him, Bu set out to kill Goku and Vegeta, but when the Saiyan released the other Bu, his power diminished. Goku and the rest took advantage of that moment to escape from Bu's body, who then seemed an accessible rival, without knowing that he had returned to his original form, the most violent and ruthless. Bu destroyed the Earth, but Goku, Vegeta, Mister Satan and Dende managed to escape to the Kaioshinkai.

In this scene, the Shunkanido technique fails to save Gohan, Goten and Trunks, which was a hard blow. Thinking about the situation, which Bu had returned to his most violent but not so strong form, with Gotenks and Gohan would have been enough to defeat him.in It was a great loss, and Vegeta was outraged with Goku for saving Dende and Mister Satan earlier than for his family. However, in the final battle against Bu, Dende and Mister Satan played an important role. Almost all the characters had already died at least once and had been brought back to life with the dragon balls. The only ones who had not gone through that experience were Gohan, Goten and Trunks. And on top of that, even the Earth, which had been saved many times from destruction, had been erased in a stroke. This situation prepared the readers for what would be the great final battle.

Vegetto's strength far exceeds that of Gohan, who has been sucked in by Boo. Vegetto cornered Boo so that he could suck him in, in order to rescue Gohan and the others inside his body. But once inside, the effect of the potalas stops. Gokú and Végéta become two separate people again, but still manage to free their own. Végéta discovers that big Boo is also captive. Boo senses that strange things are happening in his body and comes to eliminate Gokú and his gang. But as soon as the big Boo is freed, the other Boo begins to suffer. Gokú's gang take advantage of this to escape. Then Boo's body shrinks I In fact, Boo is back to his original, most brutal self! He destroys the Earth without hesitation... Goků, Végéta, Satan and Dendé manage to escape to the Kaió Shin Kai with the help of Kaió Shin. But Gohan, Trunks and the others suffer the same fate as Earth.

So far, teleportation has come in handy to get out of critical situations. But in this scene, Goků fails to save Gohan, Goten, Trunks and Piccolo. For Gokú and Végéta, the latter are close friends and important allies in battle. It must have been a great shock not to be able to save them. Even if Boo has returned to his most aggressive state, he an opponent Gokú could defeat with the help of Gotenks and Gohan. Indeed Végéta is furious that Goků saved Satan and Dendé before Gohan and the others. But in the final battle against Boo, Satan and Dendé prove to be very effective. Gohan and Goten, who were among the few Dragon Ball characters who had never died, will therefore experience death. As for the Earth, it will really disappear. These realities make readers realize that the final battle is at hand.
