It's as I thought. There's nothing to worry about Kakarot. This Majin Buu has been revealed as a weakling! At least by the measuring bar you and I have set. Is it too hard to understand, clown? The Saiyan race has evolved since that creature was entrapped. Think of what the Supreme Kai said. He's been constantly surprised by our strength. On Babidi's ship, we conquered what were supposed to be the strongest fighters in the universe, and we barely broke a sweat! Think about it Kakarot! We Saiyans have taken a ruling place in the universe that even its greatest overseer couldn't predict. And Majin Buu may have ruled in his time but now he's sorely outclassed.
It is difficult to say why, but his revival has clearly been incomplete. I had great hopes for this Majin Buu, but this deformed version is nothing but an idiot and a waste. Hmm? [to Majin Buu] Oh, what's wrong? Do you have a problem with what I've said?
Grr...grr...shut up! Shut up! [Vegeta punches Goku repeatedly while speaking] Remember I've sold my soul to Babidi! I keep no loyalties! I have a Saiyan heart that depends on strength alone! They're nothing to me!
[after hitting Goku from behind and knocking him out] I'll take care of this Buu myself! The last thing I need is for this clown to play hero again and dangle it over my head. We'll finish this fight when I return, Kakarot. Enjoy your sleep. And should your time run out before I'm done...heh heh...then we'll have to continue this another day...when I see you in hell!
