Michelangelo: [points to Donnie] Donatello over there in the purple, he's a technical genius who is, technically, a genius!
[points to Raph]
Michelangelo: Raphael over there in the red, he's like a big, cuddly teddy bear... if big cuddly teddy bears were incredibly violent.
[points to Leo]
Michelangelo: This is Leonardo, he's in the blue, fearless leader, silent, but deadly, hah!
[points to himself]
Michelangelo: And I'm Michelangelo, sporting my signature orange! I'm a triple threat, brains, brawn, and obviously a dazzling personality! Ladies like to call me Mikey!
Leonardo: [puts his arm around Mikey] Are you done?
[an unmutated turtle looks down at Raph as he kisses the ground]
Raphael: Well, uh, this is awkward.
Michelangelo: [chuckles at Bebop] Dude, bringing back the mohawk! Good for you!
Bebop: Oh ho ho, you all gots jokes, huh? Well, let's see how funny you are after we bash your heads in!
[Bebop and Rocksteady attack]
Donatello: Bogeys on the bus! Press the button!
Leonardo: What button? There are a million buttons!
[Bebop and Rocksteady see how they've mutated]
Bebop: You're a rhinoceros!
Rocksteady: And you're a... I don't know what you are!
Bebop: [sees his reflection] Huh, I'm a little piggy?
Baxter Stockman: You're a warthog.
April O'Neil: What's your name?
Casey Jones: Casey Jones.
April O'Neil: [smiles] Hey...
Michelangelo: One question... so are you two like a thing?
Donatello: Leo, you're not gonna believe this. Okay, I made this solution from the sample of the purple ooze, right, to expedite analysis of the isotope, but, while I was waiting for it to catalyse, I started thinking. If the purple ooze can people into animals, perhaps, if properly re-engineered, watch this, watch this, it could turn us... into humans.
[demonstrates by giving his turtle hand extra fingers]
Donatello: If we could get our hands on more of this stuff, it could be life-changing!
Leonardo: We don't need that kind of change.
Splinter: You can't walk away from this...
Leonardo: I told him, Master Splinter! But Raph, he never hears a word I have to say! Nah, I knew they couldn't handle the truth about the purple ooze, and you know what? They proved me right!
Leonardo: I don't know what to do. Donnie's nose is in his computer, Raph's brains are in his biceps and Mikey's head's in the clouds! I can't get them to think on the same page, to think with ONE mind!
Splinter: You shouldn't want them all to think the same, it's their different points of view that make the team strong. A good leader understands this. A good brother accepts it.
Raphael: What would Vin Diesel do? No regrets, no fear.
Michelangelo: [taps Krang suit] I was expecting way worse...
[Krang pops out]
Michelangelo: It's like a chewed-up piece of gum, with a face!
Raphael: Every minute we stay down here, Shredder gets stronger and Mikey gets more annoying!
Donatello: We're training... sort of. As soon as the sun goes down, it's Turtle time!
Rocksteady: [gestures towards Shredder] It's him!
Bebop: Hey, hey, hey, speak from your heart!
Rocksteady: Hey Mr Shredder! Big fan of your work, especially your early stuff!
Bebop: My name is Bebop. This is Rocksteady. I know that's a crazy name, right, but his ancestors are from Finland.
Rocksteady: Yeah, that's right, I'm Finnish. 'Cause when I start a beatdown, I always FINNISH it!
Rocksteady: Yeah, I said it!
Bebop: Did you hear that?
Rocksteady: I said it!
Bebop: [laughs] My man!
Rocksteady: My man!
Bebop: Gimme that foot!
[Bebop and Rocksteady proceed to high five each other with their feet]
Casey Jones: [Bangs on the cage in the Police van] Hey! Shut up back there!
[Rocksteady blows up the plane he and Bebop and the Turtles were in]
Bebop: Dude, seriously?
Rocksteady: That's my bad, I got carried away...
Casey Jones: [spots Splinter in the lair] Guys, nobody move! Don't move... there is a giant rat back there.
Raphael: Uh, yeah, we've seen him around here before. You know, there's only one way to get rid of him. You gotta get low...
Raphael: When you go at him, you gotta go fast, gotta go hard.
Michelangelo: We believe in you, Casey Jones! It's on you, bro!
Raphael: Yeah, exactly.
Michelangelo: Three, two, one... go!
[Casey charges at Splinter... who knocks him down]
Splinter: Giant rat: one. New guy: zero.
Raphael: [laughs] I can't believe it was that easy!
Rebecca Vincent: What are you?
Michelangelo: We're not really into labels.
Leonardo: Some call us freaks... monsters.
Raphael: Let's just say we're four brothers, who hate bullies and love this city.
Casey Jones: Everything's normal. And the next thing I know, I see a garbage truck, and it starts launching manhole covers!
Casey Jones: Kiss me, it'll make for a great diversion!
[April doesn't kiss Casey, people walk past them]
April O'Neil: The idea is to divert attention away from you!
Rebecca Vincent: I think you should give people more credit. They'll accept you now.
Raphael: You're probably right... but I think we'll stick with the arrangement we had.
Leonardo: You ever need us, April knows where to find us.
Rebecca Vincent: Really? You could live a normal life, like the rest of us.
Raphael: Normal... what fun is that?
Shredder: [to Bebop and Rocksteady] I'm looking for errand boys...
Michelangelo: Halloween parade, bro! it's the one night of the year we can fit in...
[comes out and walks in the parade]
Raphael: Get back here!
[pulls him back into their sewer]
Raphael: What part of "move in the shadows" don't you understand?
April O'Neil: If you want to go down swinging, these guys hit harder than anyone.
Krang: [slaps Shredder] Oh, I'm sorry, did I get a little tentacle mucus in your eye?
[Leonardo chops off the Krang suit's arm]
Krang: You think I didn't plan for this?
[summons a replacement arm and new weapons]
Michelangelo: Guys, he's literally re-arming!
Krang: You know, I'm looking forward to enslaving you! A cage full of tortoises might be nice!
Raphael: We're turtles, not tortoises! There's a big difference!
Leonardo: Yeah, turtles bite!
[fighting on a plane after losing to Bebop and Rocksteady]
Michelangelo: You can't just push past me like that!
Raphael: You were being a nitwit! You were going to let it get by you!
Donatello: I had it right in my hand, you acted like I wasn't even there!
Leonardo: It is not my job to make your presence known, okay! Get your head out of your head and communicate!
Raphael: Well, what do you expect? He's all logic, no skill!
Michelangelo: [to Raph] Well, coming from the guy who's all instinct, no restraint...
Leonardo: [to Mikey] What do YOU know about anything! You're all heart, and no brains!
Donatello: [to Leo] How could you? You may know a lot about strategy ,but you know nothing about feelings!
Leonardo: Fair enough. Wanna know the one thing I am feeling? We may be brothers... but we are not a team.
Leonardo: Mikey, we got company!
Michelangelo: Nunchuks Giganticus!
[wields giant nunchuks on two robotic arms]
Raphael: Pop quiz: What are the most important traits of a ninja?
Leonardo: Speed! Stealth!
Raphael: And honour. Where's the honour in keeping secrets from your brothers?
Leonardo: I don't know what you're talking about...
Raphael: Oh, so now you can add lying to that list!
Shredder: [holds up mutagen] This will help us build an army...
Leonardo: How're you doing up there, Donnie?
Donatello: [piloting a plane with his staff] I'm doing awesome!
[the Turtles and Bebop and Rocksteady float down a river]
Rocksteady: Bye, Turtles!
Michelangelo: That's nice of them to say goodbye...
Rocksteady: Heads up!
[the Turtles go over a waterfall screaming]
Bebop: We gotta keep our eyes out for intruders!
Rocksteady: Well, what do intruders look like?
Bebop: Anybody that's not a big pig or a big rhino!
Krang: [to Shredder] I know what you're thinking right now, of all the ways you'd like to kill me. But that would require out-thinking me. And no one, nothing is smarter than THE KRANG!
Shredder: Once the Technodrome is assembled, we can rule the planet.
Krang: I'm sorry, we? WE will rule? Ha-ha!
Shredder: We were a team...
Krang: "We were a team..." Teams are for the weak! Family is for the scared! The Earth is MY toy, and I do not like to share!
Shredder: You betrayed me!
Krang: Actually, I barely even thought about you!
[Shredder draws his blades, but Krang freezes Shredder and stores him inside the Technodrome]
Krang: Back to the toy chest, with the rest of the things I've broken! Silly little earthling!
Krang: [grabs Mikey] Come here, little turtle! Let me give you a hug, GOODBYE!
[puts Mikey in a bear hug]
Donatello: With Mikey!
[all three take down the Krang suit]
[the Turtles encounter a group of Foot Soldiers on board a plane]
Raphael: The good news is, you're wearing chutes...
Raphael: The bad news is...!
[the Foot Soldiers are thrown out of the cargo door, each of their parachutes deploying as they fall]
Leonardo: Sensei, the Foot Clan are intending to break Shredder out!
Splinter: If Shredder is free, is reign of terror over the city will begin again.
Splinter: Then there is only one question: why are you wasting time talking to a grumpy old rat? Go get him!
Michelangelo: [in tears] You should have seen the looks on their faces... it wasn't just fear, it was actual hate...
Splinter: It will be all right, my son. People fear what they do not understand.
Raphael: If there's even a chance that stuff can make us human...
Leonardo: We're turtles, whether you like it or not.
Raphael: It's not about what I like, it's about what people up there will accept!
Leonardo: True acceptance comes from within.
Raphael: Don't give me that fortune-cookie muck! You should have consulted with your brothers before you decide to do something like that!
Leonardo: I consulted with Donnie, and we both decided it was best...
Raphael: [shoves Leo] How about Mikey and me, don't we get a vote?
Leonardo: There's only one vote that counts in this team: MINE!
[the Turtles hide in the cargo hold of a plane]
Michelangelo: Isn't there supposed to be three stewardesses handing out warm towels and stuff?
Raphael: Not here, Mikey. Not for us.
[the Turtles train at the Chrysler building]
Leonardo: Okay guys, let's do this! Turtle formation!
[the Turtles dogpile each other]
Leonardo: What happened to Turtle formation?
Michelangelo: Turtle formation? I thought you said Squirrel formation!
Raphael: Why would he say Squirrel formation, you idiot?
Baxter Stockman: [mutates Bebop and Rocksteady] This is gonna be good!
Vernon Fenwick: Why aren't we going with the Turtles? When something bad happens, you want to be with the Turtles!
Raphael: [leaps out of a garbage truck] Time to take out the trash!
[attacks the Foot]
Raphael: [leaps on a Foot bike] That's how I roll!
[knocks him off the cycle]
Raphael: That's how you roll!
Baxter Stockman: Inside every human, there's a dormant animal gene. This will return them to their rightful place in the animal kingdom!
Krang: Time for a new game! Look out, Earth, it's playtime!
Krang: Place me back in!
[the android push him into the suit slowly]
Krang: Push me in, you stupid robot!
[the android punches him into its stomach]
Krang: You idiot!
Bebop: [to Casey] You're starting to be a real pain in my butt. And do you know what Bebop does with pains in his butt?
Baxter Stockman: If we can't bring him to the extraction point, we can bring the extraction point to him!
[prepares a teleporter]
Michelangelo: [on the purple ooze] It was the coolest thing I'd ever seen... It gave me hope, you know, that we don't have to be stuck down here for ever...
Raphael: So Leo told Donnie to keep it a secret, from US?
[a vortex opens in the sky]
Leonardo: What's happening out there, Donnie?
Donatello: I don't know, but it doesn't look good...
