Batman and our heroes vs. Clayface/The Joker's death/Ending

This is where Batman and our heroes fight against Clayface, the Joker is dead, and the ending takes place in Mac Grimborn Meets Batman: Arkham City.

[Inside the theater, Batman and our heroes arrive as Joker sees them]

The Joker: Hurry up and take your seats, fellas. The show's about to begin.

Mac Grimborn: Joker, don't!

Batman: Let's just talk about this.

The Joker: [laughs] Now you want to talk? Too late, fellas. [holds his gun on Talia] Give me the cure!

Ryan Heretic: You've already got the cure.

[Mac rushes in, saves Talia and gets a sword]

Batman: Mac, no!

[Mac drives the sword through Joker's chest as his body collapses on the floor]

Talia al Ghul: Problem solved.

Kion: You shouldn't have done that.

Talia al Ghul: Why? You would never do it. You left him no choice.

Mac Grimborn: Talia, the cure.

[She hands him the cure]

Mac Grimborn: Thank you. [shocked as he sees something] Talia!

[A shot kills Talia as Batman catches her]

Talia al Ghul: I'm sorry, beloved. I didn't know...

[She dies as they see the real Joker]

The Joker: [laughs] Encore! More! Bravo! [coughs]

Kion: You're alive?

Mr. E: Wait a minute. That dead body isn't the real Joker. It's a copycat.

[The fake Joker stands up and slowly transforms]

Mr. E: Or something else.

Mac Grimborn: Oh, no. It's Clayface!

Killow: That name kinda sounds inaccurate.

Captain Gutt: Ladies and gentlemen, for one night only, standing here for yours truly, and we did a good job of it, we give you... Clayface!

Clayface: [roars]

Kalmaar: Oh, boy.

Benthomaar: Oh, I see. Clay... face. Now the name makes sense. But why would he sign up with Joker and Captain Gutt?

Clayface: Easy. [turns his hand into a hammer] The role of a lifetime!

[He slams it down, but the group dodge]

Batman: One last chance.

[He freezes Clayface as Benthomaar gets the sword and slices him]

The Joker: You're making me late for my spa treatment! I mean, it's not like you've got a girl to save anymore, is it? [laughs] Oh, I'm sorry, too soon? Would a change of scenery help ease the pain? [gets a remote and pushes the button]

[The floor explodes, but the team survives as they battle Clayface's minions and Batman completely freezes him. Mac gets the cure as he drinks it]

Kion: Seriously?!

[Mac drags Clayface out of the machine as everyone watches]

Mac Grimborn: Basil, it's okay. I was able make more of the cure. I can save you, my father and Joker.

Clayface: But why would you help me? I killed two of your dragon friends in the First Realm, injured your mother in that accident, and you wish to save me? Why?

Mac Grimborn: It doesn't matter. Every decision Joker made ended up with death and misery. People die every day. We stop him. He'll just break out and do it again. And even after everything he did, I would've saved him.

[Joker laughs, but coughs and wheezes as he succumbed to his illness and dies]

Kion: Good riddance.

Rani: Everyone's outside waiting for the Joker. Someone has to tell them.

[Mac walks outside as Vicky Vale gets to him as Catwoman and Croc watch]

Mac Grimborn: Gotham, it's over. The Joker is dead for good.

[Harley gasps in horror as Catwoman and Croc are surprised]

Killer Croc: [gasps] So it's true. He's gone forever.

Catwoman: Sounds like we have a chance to hunt down Riddler. But first, Mac needs to know that you found his mother.

[Mac notices Croc on the rooftop and walks away]

[The scene changes to Croc and Catwoman showing Mac to where they found Nora]

Catwoman: See? I told you we'd find her.

Mac Grimborn: Mom. [gets his commlink] Dad, it's... I found Mom.

Mr. Freeze: [comms] What? I'm sorry, son, I must've misheard you. For a minute, I thought you said you found Nora.

Mac Grimborn: I did.

Mr. Freeze: [comms] My goodness, is she safe?

Mac Grimborn: Seems that way.

[Mac looks at his mother as the film ends]
