I took over this collection for Mugo a couple years back. If the thread's title or the logo above wasn't any indication, it contains content from SEGA's Sonic the Hedgehog series.
Also, I won't be accepting any fan characters. I mainly want to stick with things from the games, cartoons, and comics, though some exceptions may apply (Examples: Time Flux Sonic, Ashura/Glitch Sonic).
