What does it feel like to transform?
Sort of like a... good stretch.
S2 E6Bros in Space
How did you get to Revonnah?
I know a guy!
How did you know about Amber Ogia?!
I know a guy who knows a guy!
And the harvesters? Oh, wait, wait, wait! Let me guess. You know a guy.
Knew a guy. In past tense!
Oh, you're gonna pay for that!
Luckily, I know a guy! (transforms)
Who's gonna kick your teeth in present tense!
S2 E7Arrested Development
Who's more famous: The superhero, or the guy who destroys him?
Seriously, dude, you have a tail.
A b'nthak, it falls off after puberty.
Vocal pattern does not match Ben Tennyson. Please provide alternate identification.
I'm Benjamin Kirby Tennyson! (Omnitrix beeps) I live in Bellwood! (Omnitrix beeps) My grandfather's name is Max Tennyson! (Omnitrix beeps) I like soccer, and chili fries, and... I'M SCARED OF PEACOCKS!
Identity confirmed. Thank you.
What was that thing you said back at the library?
How embarrassing?
Bingo.
The De-Aging Ray! Ready to say goodbye to that tail?
I do not know. I was just getting used to it again. (His tail whacks him in the face) I am over it.
S2 E8Rules of Engagement
(about Looma) That is a very strange female.
Can I pick 'em, or what?
Ooh, something blue!
Princess, I am a Plumber, not a wedding favor.
Now you can be both!
Tennyson, Rook has been taken!
I'd had a chance to catch her if some great big...If some dainty little Acrosian waif hasn't massacred Rook's truck!
I massacre from love!
Right... (transforms into Jury Rigg)
I'm no longer worthy Ben Tennyson's hands, from this moments for, you are his "betrothed". (Hugs Ben) Tell your mother for me, Ben! I couldn't bear to see her disappointment!
...Sure thing!
The princess is taking defeat, better than I imagine.
(Threaten to Julie) Next time I see you, I will crush your skull like an egg!
Isn't this where we walk off together?
Fistina, there is something I have wanted to say to you since our eyes met this morning.
Yes (expecting Rook to announce his unconditional love for her)
You are under arrest.
S3The Frogs of War
What's with this traffic? (taps the Omnitrix)
Playing "violin" with your Omnitrix won't make it move faster.
What? Oh you mean "fiddling" with my Omnitrix?
...That as well.
Randomizer function activated.
"Randomizer function"? What's that- (transforms into Way Big and falls back into a nearby building and catches a sign that almost hit the people)
WBWay Big
Sorry! My bad. Everything's fine now, see? (transforms into NRG. Fire starts burning in a building as he accidentally fired it. NRG get outs from his containment suit and floats above the people)
It was an accident, I swear.
