I'm warning you!
Yes?
(tries and fails to activate the Omnitrix) ...I got nothin'.
S1 E7Hot Stretch
You turned human!
I do that.
SSeebik
Alright Lackno....but first finish him off.
Seebik, That's Ben Tennyson!
Don't forget Rook! Better off him too! I totally let you guys go, but this guy never gives up!
She likes you Ben-Dude!
Everybody likes me, I'm a hero!
(The Kraaho pins NRG to the ground is trying to open his containment suit)
No whatever you do, keep the suit close. Don't open me up! That will end NRG. (The Kraaho succeeds in opening the suit which releases his true form) Suckers ha ha.
S1 E8Have I Got a Deal for You
SSunder
Just hand over your new Omnitrix, Ben Tennyson, and this can all be over.
Well sure, since you're asked so nicely.
Last chance for you to quit where you're ahead!
SSunder
Last chance for you to keep your head.
Ho ho. That was like a joke, but smaller. (shocks Sunder)
It's not just rare, it's incredibly dangerous!
You don't say?
PPax
Where is the Screegit ?!
First start by telling me what happened to it!
PPax
I have no idea, I mean Screegits usually only react like this in a nitrogen filled environment, but you earthlings breath oxygen.
Surprise! Earth's atmosphere has nitrogen in it too pal!
PPax
Well, why didn't you tell me?
Why didn't you ask? It's not that sort of thing that just comes up in conversation. Oh, hi! My name is Ben. My atmosphere is rich in nitrogen, how's yours?
The Professor's motives, I can understand. That Pax fellow? Not so much.
He means well. ...Which makes him even more dangerous.
PPax
What kind of fools do you take us for?
BTBlarney T. Hokestar
What are my options?
Alright Omnitrix, I need something BIG to stop that train. You hear me? (Ben slaps the Omnitrix Core down and transforms into Jury Rigg)
Jury Rigg? How does this help anybody? (Jury Rigg slaps the Omnitrix symbol on his belt and changes to Grey Matter)
Grey Matter? Seriously? (Grey Matter bends his right arm backwards over his right shoulder, slaps the Omnitrix symbol on his back, and turns into Nanomech)
NNanomech
Oh...come on already!
Oh this is gonna hurt! (Train passes over him) YEOOOOOOOW!
