Villain Pub – The Boss Battle

Batman is about to be eaten by the shark from Jaws... when he suddenly appears at the Super Café, safe and telling Superman his story. When Superman asks how he managed to get free, Batman uses his "Because I'm Batman" schtick, but even then Superman is skeptic. It turns out that he was saved by Doctor Strange.
 * (The pub's new theme song. "Sometimes you wanna go WHERE EVERYBODY HATES YOUR FAAAAAAAACE...")
 * (The first lines of dialogue:
 * Voldemort: Holy CRAP, it's Batman!
 * Batman: Hey, what's up? Found your little clubhouse.
 * (And where has Thanos been this whole time? On the toilet.)
 * Loki: Are you sure you don't want to get in on this, Thanos?
 * Thanos: Nah. Still not my time.
 * Batman: [taking the Infinity Gauntlet] Then you won't mind if I borrow this?
 * Thanos: OH NOW IT'S ON!
 * (After Batman punches out Thanos, we cut back to Joker, who hasn't moved once:)
 * Joker: Okay, now this is just getting ridiculous.
 * [cut to Batman, now carrying the Infinity Gauntlet, Loki's scepter, and his cup of coffee]
 * Batman: Because I'm Batma-
 * Joker: Shot-in-the-face!
 * [shoots Batman]
 * Joker: [evil laugh] Finally! I got you!
 * [epic music swells as Batman rises, having caught the bullet with his teeth]
 * Joker: Aw, come on...
 * (Batman gets to punch the Joker so much that each time he starts to change back to his version from Batman: The Animated Series, then The Dark Knight, then the 1989 Batman film, then finally the '60s Batman series. He even has Cesar Romero's moustache!)
 * Voldemort: I think [Batman] is punching him back in time!
 * Loki: Should we try to stop him?
 * Voldemort: Not in this case. No, I don't think so.
 * [they wait until Joker is in his Dark Knight version again]
