- Batman: [First Lines] The nuke, where'd you get it?
- The Joker: Why, you want one? Copy bat.
- [as Batman grabs The Joker, Superman bursts into the Interrogation room]
- Superman: Get away from him!
- Batman: I'm handling this.
- Superman: [Slowly approaches The Joker, pushes the table aside and pins The Joker to the wall] You drugged me! Made me... Lois... my son.
- The Joker: First Krypton, now Metropolis. People you love tend to blow up, don't they?
- [Superman raises his fist to The Joker]
- Batman: Superman, don't!
- [Superman Punches the wall right next to The Joker's head]
- The Joker: That's why I like you, Superman. You are more gullible than...
- [Looks towards Batman, then Superman tosses The Joker to the other wall]
- The Joker: You think you can have a family. That locking me up would *magically* reform me, and they'll be safe.
- [Sits back down]
- The Joker: So big. So dumb. Now run along so I can break out of here. I got lots of planning to do to top this.
- [Superman grabs The Joker by his neck]
- Batman: That's enough!
- [Walks towards Superman to stop what he's doing, but Superman pushes Batman aside]
- The Joker: I know it's soon, but... think you'll ever love again? Maybe you won't kill your next family
- [Superman's eyes glow and then punches The Joker in the stomach, killing him]
- The Joker: Hi, gang. What'll we do now? Anyone up for pancakes?
- Wonder Woman: Joker.
- [She twists his arm]
- The Joker: What? Ow! Why does she hate pancakes?
- Green Arrow: [while fighting Nightwing] He took you in, trained you. Sure, he can be an uptight jerk, but you abandoned him for Superman?
- Nightwing (II): [Knocks down Green Arrow] I'm not Dick Grayson.
- Batman: [Coming in] This is Damian Wayne.
- Green Arrow: Wayne?
- Nightwing (II): His son.
- [Batman pushes Nightwing aside]
- Nightwing (II): But Superman's been more of a father than you ever were.
- Batman: You stopped being my son when you killed Dick Grayson. *He* was my son.
- [Defeating him in a fight]
- Batman: You're dead to me.
- Harley Quinn: [after fighting him] It's you. The way you move... The way you...
- The Joker: Pummel?
- Harley Quinn: Well... Yeah.
- The Joker: It's the love. You could feel the love, right?
- Deathstroke: Whatever history we have with our counterparts, you and I have none.
- Cyborg: I downloaded your history. You tried to kill this world's Titans.
- Deathstroke: Only a couple times.
- Cyborg: Just don't expect any warm fuzzies from me.
- Green Lantern: Oppressing your home planet isn't enough, Sinestro?
- Sinestro: The One Earth Government is similar to mine on Korugar. An alliance was logical. So for now, I tolerate humans. Even Hal Jordan.
- Green Lantern: My Doppelganger *has* joined your side.
- Green Lantern: As do all who wish to live.
- Green Lantern: [after defeating Sinestro] I'm resisting arrest... again.
- [Goes to Wonder Woman]
- Wonder Woman: Hal.
- Yellow Lantern: [Coming in] Someone call me?
- Green Lantern: [Upon seeing his alternate self] You're Sinestro Corp.?
- Yellow Lantern: Sinestro's right. Fear is more effective than willpower.
- Green Lantern: So, you ditched green and went yellow: The color of cowardice.
- [Uses his ring to attack his alternate self, but Yellow Lantern uses his own ring to deflect]
- Yellow Lantern: I'm still about Order, like the Guardians.
- [Attacks Wonder Woman and Green Lantern tries to attack Yellow Lantern]
- Green Lantern: [Sarcastically] I'm sure they're very proud of you.
- Yellow Lantern: Sanctimony is easy when you don't know what...
- Green Lantern: [Interrupting] Save it. Time to kick my ass.
- The Joker: [after defeating Batman] Now, where was I before I was so rudely...
- Harley Quinn: [Coming in] Pumped full o' lead?
- The Joker: [Turns around and sees an alternate Harley Quinn] Harley?
- Harley Quinn: Har*leen*. A little bird told me some creep was dressed up as The Joker, fighting a Batman wannabe. You got the look, and a lot of nerve. What you don't have is the right.
- [Nudges The Joker]
- Harley Quinn: The Joker was a hero, you're not fit to lick his boutonniere.
- The Joker: Harley, it's me. I'm The Joker. Look. it says so right here on my underwear.
- [Looks at his pants and Harleen fires a shot next to The Joker]
- Harley Quinn: Not funny, creep. No one pretends to be my Mr. J.
- The Joker: [setting the nuke] Let's see, baldy said remember to... Ah! There we are.
- Harley Quinn: Mr. J, it works! Oh!
- [she sees Batman coming]
- Harley Quinn: Uh-oh.
- The Joker: Harley, wait in the van. Batman and I have to talk.
- Harley Quinn: But...
- [he slaps her]
- The Joker: Go. No one likes a third wheel.
- Green Arrow: Shit!
- [He fires an arrow, but Killer Frost freezes it]
- Green Arrow: Killer Frost.
- Killer Frost: Playtime, Grundy.
- Solomon Grundy: Arrow Man!
- Superman: You thought you could fool me, Bruce? Like HE did?
- Batman: This isn't about Joker! It's about you!
- Superman: I perfected this world! So many lives lost because I held back... when I should've used ALL my power!
- Batman: For what? To control? To oppress?
- Superman: I could've prevented Metropolis! Saved my family!
- Batman: Crime took my family too, Clark.
- Superman: But you weren't the gun!
- Superman: These duplicates... Do you think there's a Lois where they come from?
- Lex Luthor: There was only one Lois.
- Lex Luthor: You're interrupting tonight's entertainment, Raven
- Raven: I detest violence, Luthor. But I'm even less fond of you.
