I really hate to break this to you, but I've been holding back the lion share of my power for the sake of amusement, but now I'm going to end this fight. But before I do, I'd like to make you an offer.
Hm...and what does that get you? With me, you would live like a God. Yes, you could have anything. Or not, you could choose to suffer and die. Your call.
Oh my. You are so naive. You know nothing of the pleasures of this universe. Any desire that you have could be instantly fulfilled. But have it your way. Die if you must. But allow me to let you in on a little secret.
Don't be glum. You should actually be flattered. I've never had to summon this much of my power to defeat someone. Fifty percent of my maximum. That's all that's required for this.
You're choosing to die instead of joining me? It's a real shame. Heh heh heh heh heh. You Saiyans are really something else. So proud. So obstinate. You're just like Vegeta and Vegeta's father and that radical Bardock. You're all alike. Too stubborn to recognize a good deal. Just like moths, rushing into a flame to die. But what can I do, you leave me no other choice. We could have been so good together.
[while in Bulma's body, about Frieza pounding Goku] Incredible. Now that's what I call speed. I can't believe that I have the privilege of watching this fight. This is monumental, what a matchup. Gosh, this is the greatest battle ever, and here I am to witness it.
