The Powerpuff Girls are suddenly brought to a Rift, and Blossom quickly deduces that they are in a "Multiverse" situation. They attempt to find a good guy to help them, but find only bad guys (or good guys turned evil). They eventually tip off the Batcomputer and Batman begins tracking them out of interest. The Powerpuff Girls eventually encounter The Rowdyruff Boys and Mojo Jojo and defeat them. Batman meets up with the girls afterward, who seem able to trust him as a hero.
