I still remember the first day I brought you here. You were small, helpless. You've changed so much since then. The harder things got. The more determined you became. The more dangers you faced, the stronger you grew as a warrior. I know I was hard on you, but it was for your own good. You're like the son I never had. I'm proud of you.
You're not stronger than me, you little runt! Your strength was tested when you were a baby! You're a third class Saiyan! I'm a Saiyan elite, you low class dog!
Oh...it's the Kaioken attack. It's like a massive upsurge of energy. Everything is heightened, power, speed, even hearing and vision improve dramatically. You sort of become a super-self. But it can only be sustained for a short time, so you have to get the job done quickly.
That's true. I could have, but the problem is there's always a chance that the increase in energy could've destroyed my body. But I'm still here, aren't I? Yeah.
[about Vegeta] It's too bad! It seems he's totally determined to end things this way! He sure would make a good sparring partner! [Krillin raises his hand to shake Goku's] Hm?
Kakarot, I have a proposition for you. I'm only going to say this once, so listen carefully. I, Vegeta, Prince of all Saiyans, would like to offer you, Kakarot, the opportunity to stand beside me in this conquest. With Nappa gone, I could use a good man. Think about it. We would rule the planets. You could have anything you desired. There's no one in the universe that could touch us. Nothing would be out of your grasp. Well, what do you say Kakarot?
I have everything I could ever want right here on Earth, so I'll have to say, no thanks. Besides, I've seen how you treat your partners, not much job security.
[to himself] Goku's insane. This guy is beating him senseless but he just keeps coming back for more. I know Goku's tough, but it seems like this time, he's finally met his match.
