Fascinating. Yes, this would be a rare match indeed.
If you don't run away...
S5 E19Krillin's Decision
Please no father! That's your weak point. Can't you see? Cell's exploiting your only weakness!
Shut up you fool! Mind your own business. I don't remember asking you for your opinion on the matter. How can you understand my power? I've gone beyond a Super Saiyan!
Move along kid. I don't have the patience to deal with you right now, you young punk!
You'll need a lot more than patience to deal with me.
[about Trunks] Darn kid. Just like his father.
S5 E20Last Defense
[about Trunks] Stupid boy! This is too good an opportunity for you to screw up!
From the looks of it 16, I'd say your batteries are running low. Now, thanks to Vegeta, I will finally reach the perfection that my designer intended.
Vegeta...I should've known.
Yes, he is a brave one. Incredibly stupid, but brave nonetheless.
You're wrong father! You can't let him reach his final form! There's a good chance that he'll become stronger than both of us!
Heh heh. But that's the thrill! Don't you wanna see this power he keeps talking about?
No. I've seen it all my life.
Honorable elder! Honorable elder!
Ah, Dende. You have sensed it as well.
Ah, yes! But who could be behind such a power? This is the most terrible energy that I have ever felt!
I do not know my son. But from the sheer magnitude of this bio-energy, it may not only destroy planet Earth but the entire universe as well!
Huh! The entire universe!?
[Cell goes into his perfect form] This is all my fault because I destroyed that stupid remote!
S5 E21Cell is Complete
[to himself] Yes, Cell's final transformation is at last at hand. Soon, he will be the greatest adversary I have ever faced.
Vegeta, you've doomed us all.
[after becoming Perfect Cell] At last. All that I have ever imagined is now mine. I have become what no other could ever achieve. I am perfect.
[as Krillin and Trunks are punching and kicking him and it has no effect] Yes, that's right children. Have your fun.
So you want to play, huh? Very well, it's my turn. Are you ready?
S5 E22Vegeta Must Pay
[about Krillin] Hah. He should feel lucky. He's the first one to be touched by my perfect body.
