Lore & Background

In the film, Mojo Jojo's origin is directly tied to the creation of the Powerpuff Girls. After the Chemical X explosion, his brain mutated, granting him superintelligence. He gains the girls' sympathy by convincing them he is also hated for his powers, and tricks them into helping him build a laboratory and a machine powered by Chemical X, which he claims will 'improve the city.' He secretly implants small transportation devices on all the primates at the local zoo, then teleports them to his lab and injects them with Chemical X, turning them into evil mutants.

He renames himself Mojo Jojo and publicly announces the girls assisted him. When his minions briefly rebel, he accidentally overdoses himself on Chemical X, causing him to grow into a giant monster. He offers them an alliance to take over the world, but they reject it and fight him, ultimately defeating him by tricking him into falling into a vat of Antidote X, which shrinks him down to his original size and allows the police to arrest him.
