Batman vs Teenage Mutant Ninja Turtles movie plot

Raphael: So, this League of Assassins seems just like your standard evil ninja deal.

Robin: Ha, hardly, despite their name. The League would be better understood as a death cult. Worshiping Ra's al Ghul, the Demon's head.

Raphael: Okay, fine. Creepy evil ninjas then.

Robin: He wants to use the League to tear down cities like Gotham and rebuild them in his image.

Batgirl: Yeah, Ra's obviously has plans for the mutagen your Shredder brought into the city.

Donatello: Ooze, we call it Ooze.

Batgirl: Really? Ugh, I do not like that word. "Ooze", blech, gross.

Raphael: Right, Shredder gives ghoulie the Ooze, they build some kind of gizmo and in return, let me get this straight, Shredder gets a pit?

Robin: The Lazarus Pit. It's how Ra's al Ghul has survived for centuries. It's magic grants immortality to any who bathe in it.

Raphael: An immortal Shredder? That would suck.

Donatello: As much as the words immortal Shredder freak me out. I think Batgirl and I have solved one of our problems.

Batgirl: Yep, with the info Donnie... I can call you that, right?

Donatello: By all means.

Batgirl: Cool that Donnie had on his T-phone, I've whipped up a retro mutagen.

Donatello: Anti-Ooze.

Batgirl: Not gonna call it that. That will reverse the effects of the "stuff".

Raphael: You're gonna wanna get that anti-Ooze away from this happily mutated turtle.

Donatello: Don't worry, it'll only work on someone who's been mutated in the last 12 hours. After that, the DNA changes are baked in.

Batgirl: Yeah, although maybe worry a little, because it's untested, right now there's a... I'm gonna say 40% chance of lethal side effects.

Robin: I agree with the turtle, go stand over there.

Commissioner Gordon: Ninjas. As if we didn't have enough problems in this city.

Batman: Commissioner Gordon.

[Gordon Turns and sees Batman]

Batman: What have you got for me?

Commissioner Gordon: It's Arkham. Alarms went off an hour ago, but when...

[Sees the Turtles]

Commissioner Gordon: What are those?

Michelangelo: Teenagers.

Donatello: Mutants.

Raphael: Ninjas.

Leonardo: Turtles.

Commissioner Gordon: Just think about your retirement. Some place where the turtles don't talk and clowns are funny.

Batman: It's okay, Jim, they're friends. Arkham.

Commissioner Gordon: Right. When my people tried to move in, they were attacked by ninjas. Like the ones that have been knocking over laboratories.

Leonardo: Shredder!

Commissioner Gordon: We've got the perimeter locked down, but we have to assume there are hostages inside. Guards, doctors, nurses. I need you to...

[Sees the roof is empty]

Commissioner Gordon: Sure, leave before I finish. That never gets old.

Michelangelo: I'm still here.

Commissioner Gordon: AAAAAA!
