Darkspine Sonic
Darkspine Sonic (ダークスパインソニック Dākusupain Sonikku), or just Darkspine for short, is a transformation that appears in the Sonic the Hedgehog series. It is the form Sonic the Hedgehog can achieve by absorbing the World Rings of rage, sadness and hatred. In this form, Sonic is slightly more violent and aggressive due to the influence of the World Rings' sealed feelings. During the decisive battle with Erazor Djinn, Sonic unwillingly assumed this form and defeated Alf Layla wa-Layla, thus saving the world of the Arabian Nights. read more
