Fan Casting Mojo Jojo (Voice Actor) in Powerpuff Girls - Aged Up

Mojo's design stemmed from the character Dr. Gori of the Japanese Tokusatsu series Spectreman. His iconic hat is inspired by a similar series Kagestar and the hat worn by its titular protagonist. Possibly more so than any other character, Mojo's proportions had the most notable changes throughout the years. In the first four seasons, Mojo looks like a more realistic chimp. However, from the Powerpuff Girls Movie onward, he is noticeably more angular. His ears, eyes, hair, and chin are sharper and longer, and his brain is bigger.
