The Batmobile races off into the distance. Finally, BATMAN catches up to the Joker's Zeplin
Joker: Batman, Got time for a little... prank?
Joker unleashes an all-out barrage of missiles, like the biggest fucking missiles you will ever see. Batman shoots his own back, and they all collide into each other in the middle of the highway releasing a violent explosion, and the, an explosion within an explosion. Afterwords: one last explosion, this time in slow motion, with tanks flying out of it.
Both BATMAN and JOKER eject from their vehicles, shooting themselves into helicopters. Then they unleash even bigger missiles, which whizz past both of the helicopters, destroying the highway on the ground below. The actions not over yet though, because in the distance there are still five more highways and on top of them, a bridge.
