When the world is threatened by an ancient evil, the four adolescent turtles must reunite and overcome their faults in order to stand against it.

Donatello: [helping various customers] Sir? Sir. Sir. Did you turn the computer on? Have you plugged it in? Yeah, that would help. No, I'm not playing hard to get. I'm telling you, sir, it's not that kind of phone line. I'm not your enemy. I'm just Donnie, your friendly IT tech support here to help you 24-hours a day, sir. Yeah, I'm sorry. Ma'am!
Raphael: [Leonardo has knocked off the Nightwatcher's helmet, and reveals that the Nightwatcher is actually Raphael. Ralpael mule-kicks him away from him] You are SO smug, y'know that? You think the world revolves around you, don't ya; that we couldn't possibly survive without the mighty and powerful Leonardo to guide us through our problems, huh? Well, I've got a newsflash for ya: we got along just fine without you!
Leonardo: Oh, and THIS qualifies as "just fine?" Dressing up like it's Halloween every night? Risking the safety of our family? I mean, come on! What were you thinking?
Raphael: Don't push it, Leo. You can't leave home and come back expectin' us to fall in line again, like your little soldiers.
Leonardo: HEY, I was TRAINING. Training to be a better leader! For you! Why do you hate me for that?
Raphael: And whoever said I wanted to be led? I'm better off callin' my own shots now, get used to it!
Leonardo: YOU AREN'T READY. You're impatient, and hot-tempered, and more importantly...
[sternly]
Leonardo: I'm better than you.
Raphael: [laughs coldly] Oh, ya know something, big brother?
[pulls out his sais]
Raphael: I'd have to disagree with you on that one.
[he gets into a stance]
Leonardo: Don't do this, Raph.
Raphael: I'm done takin' orders.
[Leo draws his swords and the fight renews]
[last lines]
Raphael: Man, I love being a turtle!
April O'Neil: [observes Winters laying on floor] It's Winters.
Michelangelo: Looks more like fall to me.
Michelangelo: Dudes, did anyone get the license plate number of that thing that hit us last night? Man, my head.
Donatello: Okay, that was just weird, first the Foot, then that hideous monster,
Michelangelo: Yeah, it looked like your mom, dude!
Donatello: Yeah, that would make her your mom too, dufus.
Michelangelo: Whatever.
Michelangelo: I have nightmares about birthday parties.
Raphael: Meet me on the roof.
Casey Jones: What is it?
Raphael: [pointing up] The roof! You know where the roof is, don't you?
Casey Jones: Pushy sidekick.
Raphael: We live together, we train together, we fight together, we stand for good together... we are ninjas. We strike hard, defend and protected and fade into the night and there ain't no bad guy or monster that gonna ever change that. That's what is important and that's why we will always be... brothers.
Max Winters: I must have hit my head really hard. I'm seeing giant turtles!
Michelangelo: I'd give us a ten for style.
Michelangelo: An eight for skill.
Michelangelo: And a two for stealth.
Casey Jones: [as April is driving recklessly] Can't this piece of junk go any faster?
April O'Neil: You wanna drive?
Casey Jones: I would as a matter of fact!
Karai: [to her ninja, as April and Casey still argue while leading the monster through the streets] You think they would be more concerned about the 13th monster.
Raphael: You're still here? Go back to your jungle.
Leonardo: At least his personality is still intact.
Michelangelo: [pauses skateboarding] Oh, so it's like Haley's Comet, only monsters come out?
Donatello: Umm, well, yes, I guess so.
Michelangelo: I'm smart.
[skateboards off-screen, sound of a loud crash]
Michelangelo: OW! I'm OK!
Karai: [sees Casey Jones outside Winter's office wearing the Cowabunga Carl outfit] You've got to be kidding me.
[first lines]
Narrator: Four turtles. Four brothers. Genetically reborn in the sewers of New York. Named after the Renaissance masters and trained as ninjas.
Raphael: And I thought girl scouts were pushy.
Michelangelo: Why skate a half-pipe when you can skate a sewer pipe?
Raphael: Why does everyone have such a hard time believing I am a good guy?
Leonardo: Funny thing about anger. Let it consume you and soon enough... you lose sight of everything.
Leonardo: Hothead.
Raphael: Splinter Junior.
Master Splinter: Raphael. Kneel!
Raphael: I did something... I did something really stupid, Master Splinter.
Master Splinter: Go on.
Raphael: I know why you chose him now. I know that there's a reason why he's the better son, and I'm not.
Master Splinter: Raphael, you always bear the world's problems on your shoulders. It is an admirable quality when you are a protector of others. But you must realize that while at times you might not be my favorite student, it does not mean that you are my least favorite son. You are strong, passionate, and loyal to your fault. These are the merits of a great leader as well, but only when tempered with compassion and humility.
Raphael: But Master Splinter, I messed up big tonight. I mean... big.
[Reveals Leo's broken swords]
Raphael: They took him.
Master Splinter: Leonardo...
Master Splinter: Ah, good morning boys!
Leonardo, Donatello, Michelangelo: Good morning Sensei.
Raphael: Sup'.
Casey Jones: [after seeing one of the monsters] You do realize that all I've got is a wooden baseball bat, right?
Casey Jones: [to April, as they climb out of the over turned van] Nice parallel parking. Next time, I'm driving!
Raphael: [as April and Casey kiss] Typical. We do all the work, he gets all the thanks.
Donatello: [talking about Raphael] Why couldn't you have sent him away to train...
Master Splinter: Donatello this home has become like an empty shell. Each of your brothers have strengths and weaknesses. You must learn to be strong when they are weak, for if you cannot learn this than our family, is lost.
Michelangelo: Sensei, are you all right?
Master Splinter: [chuckles] We must do this more often.
Master Splinter: Ee-yah!
[kicks demon back into vortex]
Master Splinter: I still got it!
Donatello: Within hours, we'll lose the city. Within days, the country. And within weeks... the world.
Michelangelo: Oh, so it's like Hailey's Comet - only monsters come out!
[from trailer]
Max Winters: Every three thousand years, the stars align. Unleashing an army of monsters.
Raphael: OK, Leo, I'll bite. What're we doing up here?
Leonardo: I told Splinter I'd get this team in shape again.
Michelangelo: Hey, I've been training. Since you've left, my videogame scores have, like, doubled.
Leonardo: Right...
Michelangelo: [talking in his sleep] Duuuude.
Michelangelo: [looking in the monster's capsules for Leonardo] Leo?
[monster leaps at window snarling]
Michelangelo: Sorry, wrong cage.
Raphael: [trying to catch a small monster] Look at you, ain't you cute! You want a butt-kicking, little fella? Yes, you do, you do! C'mon... I'm gonna drop-kick you to hurtey town, c'mon...
[is promptly bitten]
Raphael: [the Turtles are fighting Foot Soldiers and Raphael is running towards Donatello] Little help Don!
Donatello: I'm on it!
[Donatello grabs Raphael and throws him into several Foot Soldiers, who he quickly defeats]
Michelangelo: [re: Nightwatcher] I hear his bike turns into a plane, or like a jet pack. Hey Don, you're so smart, why don't we have jet packs?
Donatello: Yeah, that's good, Mikey. I don't even trust you with a driver's license.
[to the others]
Donatello: Have you seen the way this guy drives?
Michelangelo: [they hear a monster roar] Woah... Ho Ho someone's craky!
Raphael: [to Leo] ok Jungle Boy, grab a vine
Michelangelo: What do you think it is?
Donatello: An interdimensional portal to a distant world, I would assume.
Michelangelo: Ooooh! I want one!
Leonardo: This Nightwatcher character has been going around like some vigilante showboat, but his days are over.
Raphael: Hey, the Nightwatcher was the only one around to pick up the slack while you were gone. Crime didn't take a break... YOU did.
Donatello: [examining a dart taken out of Raphael] Yep. This has Winter's name written all over it.
April O'Neil: How could you tell?
Donatello: Because, this has Winter's name written *all* over it.
Donatello: [Acting as a technical consultant over the phone] Did you turn it on? Did you plug it in? Yes, I think that would help.
[from trailer]
General Aquila: Destroy them.
Raphael: This night just keeps getting better.
General Aquila: We are immortal and made of stone!
[from trailer]
Michelangelo: Did anyone get the license plate of that thing that hit us last night? It looked like your mom, dude!
[laughs]
Donatello: ...Yeah, that would make her your mom too, doofus.
Michelangelo: ...Nuts.
[from trailer]
Leonardo: Attack as one!
Master Splinter: There is no place for excuses when you are the LEADER!
Leonardo: Goodnight Dark Prince.
Donatello: [on the phone with a tech support customer] No sir, I'm not playing hard to get. I'm telling you, its not that kind of phone line!
[from trailer]
Leonardo: Within hours, we'll lose the city. And within weeks... the world.
Karai: The foot clan is owned by no one.
[from trailer]
Michelangelo: [falls into a dumpster] I'm okay!
