It was just regular mission at first to stop the Joker, Harley, and his goons... but things didn't end as expected.

Joker had gotten his hands on a new sort of contraption and decided to test it on them, once they stood in a specific area of the warehouse, Harley quickly pulled a lever and they suddenly were surrounded by some sort of electric energy that sent them away by some sort of teleportation device.

Everyone was shocked and angry. But as soon as the teleportation stopped they were all teleported to a world.. Your world..
