Mojo Jojo

Mojo Jojo is a supervillain in the Cartoon Network animated series The Powerpuff Girls. He is the series' tetartagonist as well as the main antagonist also the main archenemy of Professor Utonium and the Powerpuff Girls. He also serves as the main antagonist of The Powerpuff Girls Movie, and a side villain of Powerpuff Reborn

He is constantly plotting to take over the world and/or destroy The Powerpuff Girls. Mojo is one of the more successful villains in the series, as he defeated the Powerpuff Girls in several episodes including Mr. Mojo's Rising, Los Dos Mojos, and Mo Job, and managed to rule the world in Monkey See, Doggie Do and The Powerpuff Girls Rule. Diabolical, cunning, and menacing, Mojo is a genius evil mastermind who is determined to rule the world and destroy everything that stands in his way, including the Powerpuff Girls. Mojo Jojo is a notorious chimpanzee mad scientist, whose main goal is to destroy the Powerpuff Girls, crush Townsville, and conquer the world, in that order. In order to do this, he spends much of his time plotting and inventing new weapons or technology. This normally comes in the shape of giant robots or large energy/laser weapons. He is the archenemy of the girls and the creator of the Rowdyruff Boys. He is verbose and has high-vocabulary use and long-lasting sentences. He was the Powerpuff girls' first major villain that they ever fought, as explained in "The Powerpuff Girls Movie."

Mojo Jojo is one of The Powerpuff Girls' toughest rivals. Despite usually failing, he has managed to defeat them several times, or at least injure them badly. Mojo Jojo is also the most persistent one and is determined in destroying them and ruling the world. Due to his high intelligence, Mojo sometimes discovers some of The Powerpuff Girls' weaknesses (As seen in Not So Awesome Blossom). Mojo is also magnificent and cunning and often plays with the Powerpuff Girls' naivete.

Mojo, for the most part, does whatever he wants. He doesn't follow the rules and doesn't care what people think of him. He's also something of a loner and dislikes being surrounded by humans, and to be bothered in the middle of his experiments and plans. However, he has no problem with being assisted if the situation calls for it. Unlike most villains, Mojo is smart enough not to underestimate the Powerpuff Girls, and therefore uses his gadgets and plans to keep up with them.
