- 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?
- Michelangelo: Yeah!
- 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!
- 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!
- Splinter: Leonardo...
- 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.
- 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...
- Michelangelo: 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!
- [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.
- 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]
- April O'Neil: What's your name?
- Casey Jones: Casey Jones.
- April O'Neil: [smiles] Hey...
- [Mikey appears]
- Michelangelo: One question... so are you two like a thing?
- [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...
- [Leonardo chops off the Krang suit's arm]
- Krang: You don't think I've got spares for this?
- [summons a replacement arm and new weapons]
- Michelangelo: Guys, he is literally re-arming!
- [last lines]
- 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?
- 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.
- [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 shell 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.
- Casey Jones: Everything's normal. And the next thing I know, I see a garbage truck, and it starts launching manhole covers!
- 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.
- Michelangelo: Halloween parade, bro! it's the one night of the year we can fit in...
- [comes out and walks in the parade]
- Michelangelo: Cool!
- Raphael: Get back here!
- [pulls him back into their sewer]
- Raphael: What part of "move in the shadows" don't you understand?
- 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!
- 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!
- Bebop: What!
- 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!
- Krang: [last lines as he is teleported away from Earth] I'll be back, but a thousand times stronger!
- 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.
- Leonardo: Mikey, we got company!
- Michelangelo: Nunchuks Giganticus!
- [wields giant nunchuks on two robotic arms]
- [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]
- Baxter Stockman: Inside every human, there's a dormant animal gene. This will return them to their rightful place in the animal kingdom!
- 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!
- 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!
- [the Turtles encounter a group of Foot Soldiers on board a plane]
- Raphael: The good news is, you're wearing chutes...
- Michelangelo: Chutes!
- Raphael: The bad news is...
- [the Foot Soldiers are thrown out of the cargo door, each of their parachutes deploying as they fall]
