For as popular as The Powerpuff Girls seem to be, I don’t see a ton of cosplay from the series around the web. Maybe the stylized look puts cosplayers off? I’m not sure, but I am sure that Redditor Possibly_A_Dinosaur put a terrific spin on a Mojo Jojo costume. The villain from the animated series is the number one nemesis of the Powerpuff Girls. This is more of a realistic take on the cartoon character (well, as realistic as you can be when you’re dressed as a green ape). Possibly_A-Dinosaur used a mix of materials and techniques including painting an existing ape mask just the right shade of green and making a fake brain from insulating foam sealant.
You can see a few in progress pics below and more in an album on Imgur.
