Son Goku is the Strongest After All!! Majin Buu is Annihilated

Goku is ready to throw the Spirit Bomb, but Vegeta is in the way, and, despite Vegeta's pleas otherwise, he refuses to take out Vegeta along with Buu. Suddenly, Fat Buu gets up and holds Kid Buu down long enough for Hercule to pull Vegeta to safety. Kid Buu kick Fat Buu aside, and Goku throws the Spirit Bomb. It hits Kid Buu, but he starts pushing it back. Goku uses all of the remaining energy he has left trying to push it back into Kid Buu, but he is too powerful. After a brief panic, Vegeta suddenly remembers that they still have a third wish with Porunga. He instructs Dende to wish for Goku's power level to be restored to its normal, healthy level. The wish is granted, and upon turning into a Super Saiyan, Goku is easily able to force the Spirit Bomb back at Kid Buu. As he does so, he silently wishes that Buu had been a better person, and hopes to fight him as a different person, some day in the future. The Spirit Bomb hits with full force, finally destroying the evil, childlike Majin Buu permanently. After billions of years of destruction, he has finally been brought to justice.
