- Shredder: Patience is the greatest virtue of a conqueror. For years we've been hiding in the shadows, observing the city, biding our time. When dawn breaks tomorrow, the city will awaken to new rulers. Tonight, the Foot Clan emerges. Tonight, war begins!
- Splinter: Remember what I taught you! It is when we are together that we are the strongest! I only hope that we are strong enough...
- Bebop: You green dweebs think you got the best of old Bebop, do yah? Well, you's all wrong! Cause Bebop's the best there is!
- [bumps his head]
- [the Turtles find a bag of money]
- Michelangelo: [on phone] Hello, Rupert's Pizzeria? Yeah, I'd like to order 2000 extra-large cheese and pepperoni and 5000 orders of breadsticks to pick up please...
- [Leo, Donnie and Raph glare at Mikey]
- Michelangelo: Uh... never mind, dude. Wrong number.
- Raphael: [on Wingnut] For a moment, I was worried we were gonna have to deal with extraterrestrial intelligence!
- Leonardo: Just be careful, Raph, the crazy ones are usually the most dangerous ones.
- Raphael: I'll say.
- Michelangelo: ...what are you looking at me for?
- [the Turtles encounter Rocksteady in the underground metro]
- Michelangelo: That's it, I'm never taking the subway ever again!
- Donatello: I think the odds of running into a rhino during your daily commute are negligible, Mikey.
- Raphael: What daily commute? He just sits on the couch and plays video games all day!
- Leonardo: [to Raph] You know, people in glass houses shouldn't throw stones.
- [Bebop appears to help Rocksteady fight the Turtles]
- Raphael: I knew it! Whenever old horn-head shows up, pig-brain is never far behind!
- Michelangelo: He probably got on the wrong train, like 12 times or something.
- Leonardo: Do I need to bring up glass houses again, Mikey?
- Michelangelo: Hey, that only happened once!... This year... So far.
- Splinter: A war is coming, my sons. These challenges will be the greatest our family has ever faced. But we must not fear, for the true strength of a ninja comes not from an absence of fear but the mastery of it.
- Shredder: You wretched mutants still think you have a chance? You are foolish than even I thought!
- Michelangelo: Yeah, I get that a lot from people, actually... wait, what?
- Michelangelo: [on Wingnut] Would you say he's nutty? Or maybe even... batty?
- Donatello: He's got a screw loose, that's for sure.
- Michelangelo: So guys, if Bebop is trying to break into the safe, does that make this a... piggy bank?
- Raphael: [annoyed] Leo, can you talk to this guy?
- Leonardo: Guess he's trying to bring home the bacon, huh?
- Donatello: Please, not you too Leo...
- Leonardo: [on Karai] Seriously, what is the problem with this woman?
- Michelangelo: Guys, you think maybe she has a crush on me or something?
