I'm working on a Sonic Character Creator in Paint! To use it you will have to copy and paste it onto some kind of picture editing software such as Paint, GIMP, etc, etc. Then you can put shoes on your character or a shirt. I haven't completed it yet but at the moment it's like a Sonic Recoloror I guess... I'll try to post it here when it's done.
UPDATE: If you have a specific color you want a character, shirt, pants, etc, etc, then tell me and I'll try to make it! And also, If you want a me to add a certain character to the next version then tell me about that too!
