As far as I know there is: Sonic himself, Shadow the hedgehog, ultimate life form. Silver the hedgehog, from the future. Manic; Sonic's brother. Sonia; Sonic's sister. Queen Aleena; Sonic's mother. Amy Rose, friend of Sonic. Scourge the hedgehog, old character also known as 'Evil-Sonic'. That's all I know of. !
If you are talking about for Sonic... There are no Amy Rose or Shadow skins for him. Try to make a texture hack. That seems to be the only way.
