For those of you who don't know, MUGEN is a free, downloadable fighting game engine. It takes a bit of work to set up and seems confusing at first but is worth it if you like fighting games. You can pretty much have any character from any fighting game you want fight on just about any level you want since people make their own characters and levels. And there are TONS of them. There are Street Fighter, Mortal Kombat, Super Mario, Legend of Zelda, Megaman, Sonic characters and more. Even cartoon characters.
ANYWAY, it happens to have the Powerpuff Girls and I've been thinking about editing their sprites into their Superhero versions (Liberty Bell, Mange, and Harmony Bunny). I've also been thinking about editing them into...The Powerpunk Girls! It'd take forever but it'd be pretty awesome I think. Anyway, here's a few pics of MUGEN below. And there are also tons of videos on Youtube as well. Check the Sprite section for a sprite of Brute I made using Buttercup. Below are a few pics. :P
