sonic.exe:the Guilt-ridden demon.

this is my au where he's Sonics younger twin brother, but sonic.exe was cursed by a witch which is why he's a demon, he was with longclaw when he was 4 and Sonic was 8, but then Robotnik kidnapped him and began experimenting on him, forcing him to do some bad things like enslaving people...he is childish in my au, at least sometimes.
