In Townsville jail, Mojo Jojo is reading a newspaper. "Townsville's Museum is once again saved by the beloved kindergarten superheroes, the Powerpuff girls." Mojo crumbles the paper and says, "Powerpuff girls, those brats are always unstoppable whenever it comes to my devious schemes." He throws the crumbled newspaper onto the ground.
A police officer comes and unlocks Mojo's cell. "Alright Mr. Jojo," he says, "someone's here to pick you up and we're releasing you to her custody." Mojo walks out of the cell and out of the prison house. He sees a woman wearing a hat that covers her eyes. "Your ride." She says, standing next to a car. Mojo walks over to the car and the woman opens the door, allowing him to enter. "Take me to the observatory at central park." He says. The woman enters the driver's seat and says, "Oh no, you're in my world now." She takes off the hat, revealing herself to be Harley Quinn.
Mojo tries to get out of the car, but the doors automatically lock. Harley presses on the gas pedal. She starts to drive wrecklessly through the street, skidding across the sidewalk, breaking a fire hydrant, and driving through a crosswalk without yielding to the pedestrians crossing. "Hey!" yells Mojo, "I have no idea who you are but you are a crazy driver!" Harley just ignores him. She then says, "Wow mama! Check out that cute hitchhiker!" The Joker holds up his thumb, pretending to hitchhike. Harley steps on the brakes, causing Mojo to hit his face in the front seat.
The Joker enters the backseat of the car to where Mojo is sitting. "Joker." He says. "Mojo Jojo," says the Joker, "So pleased to finally meet you." Harley drives the car away.
Later the car is still driving wrecklessly throughout the streets of Townsville. "What do you want?" asks Mojo. "I would like to make a deal with you." Says the Joker. "What deal do you want?" asks Mojo. "I say we have a lot in common." Says the Joker, "We both are criminals who are striving to do evil." "What evil have you done in the City of Gotham?" asks Mojo. "I have been committing a lot of destruction and misery throughout Gotham City." Says the Joker. "And I am always that close to achieving my goal. And the only obstacle that gets in my way all the time is that pointy-ear crusader that goes by the name 'Batman'." "So do I," says Mojo, "I always tried to achieve my goal of taking over the world. But my plans have always been shut down. Thanks to those three-flying brats called the Powerpuff Girls." "I knew that you would say that." Says the Joker, "So here's the deal: I help you destroy the Powerpuff Girls and you destroy Batman for me. And then you can take over both Townsville and Gotham."
"Well what do you have that can bring those girls down for good?" asks Mojo, "They have superpowers that are even stronger than my biggest robot." "I know," says the Joker, "That way I have this." He opens a container and reveals the big vile of Chemical X. "See," he says, "Chemical X. Once I fill up the ultimate weapon with this, those Powerpuff brats will be here no more." Mojo thinks and says, "Alright, you have my word. And that Batman will be gone too." "Very well," says the Joker, "deal?" He gives Mojo his hand. "Deal." He says, taking Joker's hand.
