revenge on the Professor for replacing him with the girls, Jojo gains the girls' sympathy by convincing them that he is also hated for his powers and tricks them into helping him build a laboratory and machine powered by Chemical X, which he claims will earn them the public's affections. Afterward, Jojo rewards them with a trip to the local zoo, where he secretly implants small transportation devices on all the primates there. That night, Jojo brings the primates to his lab and uses his new machine to inject them with Chemical X, which turns them into evil mutants like himself. The next morning, after the Professor is released from prison, the girls show him all the "good" they have done, only to discover that the primates are attacking the city. Jojo, renaming himself as Mojo Jojo, publicly announces the girls assisted him, which damages their reputation further and makes the distraught Professor lose faith in them. Dejected, the girls exile themselves to an asteroid in outer space. Mojo Jojo announces his intention to rule the planet, but becomes frustrated when his minions disobey him and concoct their own plans to terrorize Townsville. Overhearing the turmoil from space, the girls return to Earth and rescue the citizens, realizing they can use their powers to fight the primates. After his army is defeated, Mojo Jojo injects himself with Chemical X and grows into a giant monster, overpowering the girls in an intense battle. Rejecting Mojo Jojo's offer of an alliance to take over the world, the girls push him off a decrepit skyscraper just as the Professor arrives with an antidote for Chemical X to help the girls. Mojo Jojo lands on the Antidote X, which shrinks him down to his original size, battered and defeated. The girls consider using the Antidote X to remove their powers, thinking they would be accepted as normal girls, but the people of Townsville protest against this, apologize for misjudging them, and their heroism is praised. Townsville's Mayor requests that the Professor authorize the trio to use their powers to defend Townsville, to which he and the girls agree, becoming the city's beloved crime-fighting superhero team "The Powerpuff Girls".
