Old Buu Emerges
Buu is about to blast Vegeta, when suddenly Hercule starts to taunt him. Buu lets Vegeta go, and turns his attention to Hercule. The world champ, thinking that it's all a dream, tries to destroy Buu, but is obviously ineffective. Buu winds up to punch him, but suddenly stops. He wrestles with his mind for a moment, and then spits out the fat form of Buu, who, though not part of his physical being, was still inside of Kid Buu. Hercule tries to beat up Buu again, but fails. Buu sends a blast toward Hercule, but it is knocked away by the old Buu, who has regained consciousness. Meanwhile, Goku still can't gather enough energy. He starts losing energy, and falls to the ground in his normal form.
