Darkspine Sonic, World of Sonic Online Wiki

Darkspine Sonic is a transformation of Sonic the Hedgehog, when Sonic's Fire Ring places on him. As the World Rings are what keep the world of the Arabian Nights together, it appears that Darkspine Sonic is also capable of warping the appearance of the reality of the Arabian Nights' universe to some degree: with one gesture, Sonic was able to revert Erazor Djinn's realm back to normal while also expelling the World Rings' power from his body.
