Well I've been following this project for a little while, but I wasn't able to contribute anything due to excessive work at the college. Anyways, I remember reading something about (among others) a Sonic the Hedgehog world too in the story idea's section. I'm unsure if that is actually the case or not, but I had a little free time so I decided to draw out a version of Chaos 0 on my Wacom tablet in case you guys wanted to use it. It's a bit unclean since I started running out of time towards the end, but if you would like to use it you are more than welcome to touch it up a bit. Already separated head into different symbols though to make it easier to move around the back pieces of the head behind other layers(though I still included original head uncut if you want to separate it a different way).
PS: used the cock from the ditto file as a template since I thought it suited the character type perfectly, so due credit to the person that created that. And since the character actually can make tentacles out of himself, I suppose it's a good setup for any of you tentacle rape fans out there, though I probably won't be working on that
Sorry about wall of txt, i'm done :3
