I will not be humiliated by a child! This has gone far enough! I am tired of playing these games! Grrr.... [to himself] This can't be happening. I am complete. It is impossible for a Saiyan child to defeat me! I am the ultimate fighter. I have no equal. Yet, somehow this one is different. Very well, if I must prove myself once again then so be it but this will be the last time. Grr...
What are you so afraid of Cell? Isn't this what you wanted? I warned you! I told you what would happen if you pushed me too far! But you didn't listen! You forced me to awaken my hidden power! And now that you've seen it, you're afraid...because you know that I'm going to destroy you!
No! He's a boy! There's no way that little brat can be so strong!
Gohan! You've got to take Cell down now before he can regenerate!
Take him down now? No, I think I'll wait. I'm going to let him suffer for a little while.
[after getting rammed in the face by Gohan] Ugh! You're not a boy...you're a monster! [Gohan kicks Cell in the stomach and Cell begins to choke] What have you done to me!?
