[while draining Piccolo's energy] Ah yes. This is invigorating. We should have done this sooner!
Stay out of this one Vegeta. I owe him. He's mine. If he manages to get by me, then he's all yours. How does that grab you?
I don't care if you want to fight him. I don't even care if you get yourself killed. But I do care if he manages to steal more of your energy and makes himself even stronger, so just keep that in mind while you're having your little fun, got it?
Yeah, I got it. I'll make sure that doesn't happen again.
[to himself] Heh heh heh heh heh heh heh heh. Well, I will make sure that it does happen.
[to Dr. Gero, while grabbing Dr. Gero's hand] You know, I used to be like you. One day you'll learn...that the more you hurt others, the harder your life becomes. It's simple. Your desire to kill is killing you! [Piccolo chops off Dr. Gero's hand with one swift blow] It's a darn shame! You could've put this hand to good use! What a waste of technology!
I do not understand! My data indicates that their abilities could not have improved this much!
Your data probably would've been accurate if we hadn't been warned about your arrival three years before you got here. In other words, we knew you were coming so we got all of our ducks in a row!
Ducks? That makes no sense! What do you mean!?
I mean that we've been preparing for you my friend!
[about killing Dr. Gero] How about the coup de grâce Piccolo? Or do I have to step in and handle it?
No! This is my job! I know if the tables were turned, this guy wouldn't hesitate. Believe me, no problem.
