Mojo Jojo is one of two main antagonists in Powerpuff Girls Z.
Ignoring the Origins in the original version, he was not a lab assistant in the anime, and as such had nothing to do with the creation of the Powerpuff Girls. Instead he was an ordinary zoo monkey who was made fun by people and decide to seek revenge on humanity after the rays of Chemical Z made him intelligent. He is physically more powerful then the original version of the character, able to fly and throw a dozen punches at one time. This version of Mojo however frequently has an immature attitude and makes the most childish flaws thorughout his plans. While the original Mojo was portrayed as one of the most competent and genuinely threatening villians in the series, the anime version is more of a rather inept comic and is seen by Powerpuff Girls as more of an annoying nuisance then a dangerous enemy. The anime Mojo also does not repeat his questions as the original Mojo does, instead in the Japanese version, ending most of his sentences with his name. He is the same size as the original, as the giant cape conceals his small figure. He never became a part of The Beat All (Mojo, HIM, Princess, Fuzzy), as there were no beat alls in the anime, however, he did forge an alliance between himself, the Gangreen Gang, and Fuzzy Lumpkin, though this group was not referred to as the Beat Alls.
