Exactly as the title says. ;) Another gift for Sefra's birthday, though the idea'd been running around in my head for a while now. The concept of putting an anthro in robotnik's outfit came from chaoscroc. Least his Egg Legion stuff is what got me thinking about it! That and reading the Sonic comic.
Matured for the suggestiveness and technically Sefra's naked. It's cartoony naked in my book, but I don't know if that's supposed to be considered "Tasteful/artistic nudity" or "suitable for all-ages" so why risk it? :p
