Vegeta overpowered Cell easily, and you were in shock. 

(Y/N): Vegeta's kicking his ass! Wow, all that training in the Time Chamber really paid off!

Vegeta: HAHAHA! Well, that's the closest thing to damage you've done since we started this fight. 

Cell: Allow me to fix that. 

Nearby... 

Krillin was flying nearby and he sensed Vegeta's Chi. 

Krillin: HOLY CRAP! Is that Vegeta's Chi?! This I got to see. 

Back on the island... 

16 and 18 were in shock. 

18: That's Vegeta? I ... kicked his ass, and now he's kicking Cell's ass. 

Indeed, no mater what Cell did, Vegeta had clearly overpowered him! 

Vegeta: I thought this was a fight, don't hold back on my account. 

Cell: HAAAAAAAAAAAAAAAAAAAAA! 

He powered up and you and Trunks knew who was the stronger one. 

Trunks: Vegeta is going to win this. 

(Y/N): Yep. Clearly, he's the stronger one. 

Cell hit Vegeta in the face, and he spit some blood out. 

Vegeta: So, that's it? I guess I trained a bit too hard for you. 

Cell: This can't be possible! You're not Vegeta ... are you? 

Vegeta: No. I'M SUPER VEGETA! 

(Y/N): LAME! 

Cell: What are you saying?! 

Vegeta: I can't be bothered to explain, figure it out for yourself. You should be more concerned with you. 

Cell: ARGH! IT CAN'T BE! 

You and Trunks just kept watching as Vegeta pulverized Cell. 

Krillin also saw everything nearby. 

Krillin: Those are (Y/N) and Trunks. Wait, are they as powerful as Vegeta too? Where are Goku and Gohan now? I m- THE ANDROIDS?! Did none of them notice? 

He then looked at the remote in his hands. 

Krillin: Okay, here goes nothing. 

He started to sneak up behind them. 

Vegeta: You know, those two over there are probably on the same level as me. 

Cell: WHAT?! 

Vegeta: Is this all you had? The Runt and the Green Man went on about how strong you were! I've wasted my time! 

Cell: ARGH! IF ONLY I HAD MY PERFECT FORM! 

Vegeta: Say what now? 

Cell: I'm only Semi-Perfect. 

Vegeta: How can you be Semi-Perfect? You're either Perfect or you're not me. 

Krillin continued to get closer and closer to 18. 

Krillin: Okay, Krillin, pull yourself together... She's right over there, standing there like a... mechanical angel. And all I have to do is push this button and... watch her explode. Everywhere. Little bit of blonde hair here... her blue eyes there... and then it's done! I-I mean, she probably won't even feel it, or even know what happened, just her life... ended in an instant... by me... with no DragonBalls to wish her back when Cell dies... Oh, come on, Krillin! Be strong for ONE SECOND in your WORTHLESS life, and PUSH THE STUPID BUTTON! IF YOU DON'T, EVERYONE YOU KNOW AND LOVE IS GOING TO DIE! INCLUDING HER!!! 

He then dropped the remote. 

18: Huh? 

Krillin: Uh ... h-hi. 

18: It's the cute guy! H-Hi. 

She saw the remote by his feet. 

Cell: Listen, how about you let me absorb Android 18, and then I will be at the level that you desire. I mean Saiyans are a warrior race at heart! The stronger the opponent, the greater the joy! 

Vegeta: You seem to know a lot about us. Fine, I guess I can let this slide for a good fight. 

(Y/N) and Trunks: NO! 

You both stopped Cell. 

(Y/N): You're not going anywhere, you bastard! 

Trunks: We won't let you get away with th- 

Vegeta hit you both! 

Vegeta: HOW DARE YOU! 

Krillin: Please don't kill anyone. 

16: We have not killed anyone. 

18: And we haven't planned on killing anyone. The only one we want dead is Cell. 

Krillin: Then this makes things a lot easier for me! 

He destroyed the remote! 

Cell: Huh? 18! 

(Y/N): WHAT?! 

Trunks: Krillin is there too! 

(Y/N): EVERYONE! MOVE YOUR ASSES NOW! CELL IS HERE! 

Cell: My meal ticket is here! 

(Y/N) and Trunks: OH NO YOU DON'T! 

You both went after Cell! 

Cell: VEGETA! (Y/N) AND TRUNKS ARE PICKING ON ME! 

Vegeta: LEARN TO SHARE YOU TWO! 

He smashed you both together! 

(Y/N) and Trunks: AGH! 

Cell: That's better. Now then- 

He appeared before the two Androids with 16 getting back up. 

Cell: Don't force yourself 16, you can barely fight. Vegeta's here to help me be complete too. 

Krillin: WHAT?! WHY NOW OF ALL TIMES?! 

You then got up. 

(Y/N): WHY YOU! YOU- 

Trunks: YOU ASSHOLE! 

Vegeta: Oh, so I see the Brat has some fight in him. 

Trunks: I WON'T LET THE FUTURE END UP IN HELL AGAIN! 

Vegeta: What are you doing? 

Trunks: What am I doing? 

Vegeta: Thwarting my plans? 

Trunks: Thwarting your plans? 

Vegeta: Are you? 

Trunks: YOU KNOW WHAT?! YES! 

He blasted Vegeta! 

Vegeta: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

He was sent flying so far! 

(Y/N): Trunks! HOLY CRAP! GREAT JOB! THAT WAS AMAZING! 

Trunks: Dad, there's a time and place for compliments, but not- 

(Y/N): YEAH! 

You both went SSJ and charged at Cell, but- 

Cell: WHITE DRAGON SOLAR FLARE!! 

Everyone: AAAAAAAAAAAAAAAAAARGH! 

Cell then grabbed 18! 

18: NOOOOOOOOOOOOOOOOOOOOOOOOOO! 

Krillin: 18! 

16: 18! 

(Y/N): SHIT! 

Vegeta then returned. 

Vegeta: YOU DAMN LITTLE BRAT! I- 

He then saw Cell transforming. 

Vegeta: Well, guess this will be all worth it. 

Cell then transformed into his final form!
