The United Underworld is an evil organization that is formed in Batman: The Movie.
Its main members are the four main enemies of Batman: The Catwoman, the Joker, the Penguin, and the Riddler. Several pirates were working for them, the only ones with names being Bluebeard, Morgan, and Quetch. Their base was inside a bar next to the ocean. Their objective was to take over the world, and to kill Batman and his partner Robin so they couldn't stop them.
