[after ramming his fist into Cell's gut] What's wrong? I hope I'm not making you uncomfortable.
Grr...what's wrong!? I'll show you- oh wait...you're making a joke...heh heh heh heh heh. I do so enjoy your classic Saiyan wit.
Thank you.
You insignificant pest! Are you really so proud of these irritating little tricks you've learned? You'll need much more if you ever hope to beat me!
You fool! Have you forgotten? I know you! Your cells are woven into my very being! You, Vegeta, are a part of me!
Now I'm going to take you apart! How ironic!
[to himself, about Vegeta] Father, one day I will prove myself to you. Maybe then you'll understand. All of these dangers that you're so eager to face, you don't have to face them alone.
[after Cell punches him in the face] That one was free. Now I'm going to show you what true power really is.
You're not Vegeta. You're not! You've changed. You've...you've become something else.
Heh heh heh. That's right. I am Super Vegeta.
