This article is a disambiguation page for Mojo Jojo
Mojo Jojo is an evil anthropomorphic ape, and a supervillain in the Cartoon Network animated series The Powerpuff Girls and its anime spin-off, Demashita! Powerpuff Girls Z. He is the number 1 archenemy and the real father of the Powerpuff Girls. He is very redundant, and often states the obvious. His first appearance was in Monkey See, Doggie Do of the 1998 TV Series of the Powerpuff Girls.
Some time before deciding to create the Powerpuff Girls, Professor Utonium purchased Mojo Jojo, then a normal monkey named Jojo, to be his house pet/lab assisting. However, Jojo was incredibly untrained, often going into destructive rampages and breaking things around the lab and house. It was during one of these rampages that led to the creation of the Powerpuff Girls: While Utonium was mixing the ingredients necessary to create them, Jojo shoved him, causing him to unintentionally spill an untested liquid, Chemical X, into the mixture and give the girls their enhanced powers. Caught in the ensuing blast, Jojo was also affected: his brain swelled in size, giving him near superhuman intelligence and the ability to speak. However, he was immediate forgotten about as Utonium's attention was completely taken up by the girls and he fled the house, vowing revenge on the man who had forsaken him.
