Yes, he's just a little boy, that's true. But he's very strong. And he has a power level even higher than yours little brother. And if he ever learned to control it, it would be very bad for us! Heh...so, you could see, I have no choice! He must die! Now!
[to himself] You are the first Saiyan to ever damage me like this my nephew. You are a true warrior who was worthy of being a Saiyan. And so, I will give you a death that is also worthy of a Saiyan.
[to himself] How could that little brat's attack weaken me so much!? [to Goku] Kakarot, you're a fool! How do you expect to dodge that beam and hold me at the same time?
Hold on Goku, I'm almost ready! [to himself] So, you're going to sacrifice yourself? Goku...how very noble of you. And how convenient for me. Then again, even if I do kill you, it's only a matter of time before your friends wish you back with the dragonballs...too bad.
Heh, gladly. On this planet, we have something that we call the dragonballs. When all seven balls are gathered together, they have the power to grant any wish, and that includes bringing the dead back to life. So, you see, it's Goku who will have the last laugh.
Ha ha ha ha ha. No. I'm afraid you're wrong green man. This device on my face, it's...it's also a transmitter. My Saiyan comrades heard every single word.
The two of them. Now they'll come. I know they will. [coughs up a lot of blood] They will. I know they will. And once they arrive, you'll be powerless to stop them. There's nothing you could do. They'll seek out these dragonballs and they'll destroy everything in their path. You, and every living thing on this planet will be wiped out. They'll destroy you all. Heh he he.
Heh he he he he he he he. Exactly. Those dragonballs caught my interest. Just think of the possibilities Nappa. If we can get our hands on those seven dragonballs, then we can wish for anything we want. Anything at all. Wouldn't you say that's worth making a little trip?
What? Living forever? That sounds great! Yeah, and if we can't die, that means no one'll ever be able to defeat us. So what the heck would we need Raditz for?
