Promised to do this after beatin' the final level. Nuh, this is NOT some form made by a fan. Darkspine Sonic makes an exclusive appearance in the game Sonic and the Secret Rings. When Sonic collects all of the Seven World Rings in the Arabian Nights, Sonic will under go a transformation much different from Super Sonic. In this form, Sonic possesses dark power and great speed. He is able to regenerate his own soul (done by shakin' the Wiimote). Unlike Super Sonic, Darkspine Sonic's voice is a bit different as it starts grindin'. Since the Rings embodied various emotions, Sonic himself undergoes a bit a change as he seems to sound more aggresive but he is still himself. Sonic is also able to dimiss this form at as well.
