Darkspine Sonic is one of Sonic's super transformations, appearing in Sonic and the Secret Rings. Rather than Chaos Emeralds, he uses the power of the World Rings. He is playable in the final battle against Alf-Layla-wa-Layla, an enhanced form of Erazor Djinn. In this form, Sonic has increased strength and the ability to fly, along with his ring powers Time Break and Speed Break. His attacks are also more close-combat based, as opposed to the boosting and energy moves that Super Sonic uses. He does not lose rings gradually like Super Sonic, but he can lose rings from being hit.
