Sonic the Werehog

EN:
Sonic the Werehog is Sonic the Hedgehog's bestial werewolf-like form in Sonic Unleashed. This form was created when Sonic accidentally absorbed a large dose of Dark Gaia's energy, although the transformation itself would only be triggered by nighttime and remain active until daytime. Due to this form's unique traits, Sonic the Werehog is arguably a hedgehog/Gaia Gaia's Minion hybrid. Sonic lost this form permanently when Dark Gaia reclaimed the energy that caused the transformation.
