Sonic the Werehog

Sonic the Werehog (also known as Werehog Sonic, Werewolf Sonic or simply Were Sonic) is a corrupt transformation that Sonic the Hedgehog undergoes in Sonic Unleashed. It is caused by Dr. Eggman and a special ray that hits Sonic with Dark Gaia's power. Sonic finds out at sundown he changes into the Werehog. When Dark Gaia awakened, he tried to destroy Chip but Sonic managed to push him out of the way. Dark Gaia, outraged, took Sonic's Dark powers away from him
