Canon Bio
Mojo Jojo is the Powerpuff Girls' archenemy, a mad scientist simian with great intelligence, who speaks in a convoluted, repetitive manner. Mojo Jojo was Professor Utonium's reckless lab assistant, Jojo, before Professor Utonium created the Powerpuff Girls, and it was Jojo who caused the Professor to accidentally add Chemical X to the mixture. He is the archenemy of the Powerpuff Girls; he cites his reason to be a villain as jealousy of the affection they received from the Professor that he did not. He has green skin, pink whites in his eyes, a huge, exposed brain under his hat caused by the explosion that created the girls, and wears white gloves and boots, a blue suit with a white belt, and a long wavy, purple cape. Despite his high intelligence, he is known for planning his schemes badly. However he is a master at manipulation and trickery, oftentimes fooling the girls into thinking he's changed despite their constant encounters. He also played a paternal role to the girls in The Powerpuff Girls Movie, in which he and the girls were treated as outcasts, though this was to manipulate them into helping him become the villain he is now. He also acted as a teacher in the episode "Forced Kin", where an unstoppable alien force was beating the girls. He forced the girls to "think evil" by committing crimes. In the end, the alien force was beaten by Mojo Jojo, who became enraged when it took over Townsville before him. Mojo is often beaten to a pulp by the girls. In "Telephonies", Mojo Jojo is one of the victims of the Gangrene Gang's crank calls. The girls attack him while he is sleeping, but fly away when he explains he wasn't "planning to do any evil schemes. Today." His catchphrase in "Just Another Manic Mojo" was "Curses!" Humorously, he is shown to have a civilian life; he is often shown walking around in public without the citizens of Townsville running in panic, and even buys groceries legally.

Appearence in Ultima
Mojo Jojo has appeared a few times in the Ultima stories (mostly in the Crossing of Universes). He is one of the three villains who interviews newcommers into the Organization alongside Pete and Hamsterviel,
