Sonic The Werehog

Sonic the Werehog[2] (ソニック・ザ・ウェアホッグ[2], Sonikku za Weahoggu?), also known as simply the Werehog (ウェアホッグ, Weahoggu?) for short, is a transformation that appears in the Sonic the Hedgehog series. A bestial, werewolf-like form of Sonic the Hedgehog, this extreme physical transformation[3] was created when Sonic accidentally absorbed a dose of Dark Gaia's energy, although the transformation itself would only be triggered by nighttime and remain active until daytime.
