The End of Super Saiyan 3

Good Buu Emerges

As Goku continues gathering energy, Kid Buu suddenly begins acting strangely in Mr. Satan's presence. The monster looks nauseated and, moments later, coughs up the original fat Majin Buu from within himself. Dende, watching from the distant planet of the Supreme Kais, realizes that Good Buu's presence inside Kid Buu had been preventing the creature from harming Mr. Satan. With that restraint now gone, Kid Buu wastes no time and delivers a vicious punch straight to Mr. Satan's face.

Mr. Satan tumbles across the ground, convinced this must all be a terrible dream. He scrambles away and shouts hollow threats from a safe distance, but Kid Buu merely laughs and beats his chest like a wild ape before charging at him again.

The Battle of Two Buus

Before Kid Buu can reach Mr. Satan, a sudden energy blast cuts between them. Good Buu stands defiantly, declaring his hatred for Kid Buu and warning him not to touch Satan. The two Buus launch at each other with ferocity. Kid Buu lands a devastating kick, but Good Buu recovers and retaliates with a powerful headbutt. Kid Buu shrugs off the impact, grabs Good Buu by his forelock, and slams him around violently.

Good Buu fires a blast that tears away half of Kid Buu's torso, but the evil Majin regenerates instantly. Down below, Vegeta screams at Goku to finish gathering his energy, but Goku admits his power is fading. Moments later, he drops out of Super Saiyan 3 entirely. Kid Buu rockets through the air and blows off Good Buu's head, though Good Buu also regenerates. Mr. Satan cheers his friend on, but Good Buu confesses he cannot win this fight. Vegeta watches grimly, concluding that the situation has deteriorated into the worst possible scenario.
