Wolfman, alternately called Ōkami-Otoko or Hito-Ōkami, is a werewolf consistently aligned with Western Yōkai forces, frequently serving antagonists such as Backbeard. His visual design varies across media but always incorporates wolf-like features: sharp claws, prominent fangs, pointed ears, and substantial body hair, often contrasted with formal business attire. Initially depicted solely in full wolf form without transformation. Within the manga *The Great Yōkai War*, he represents England within Backbeard's invading army, battling Japanese yōkai on Kikaiga Island. This narrative frames Western monsters like Wolfman as occupying forces, mirroring post-WWII American influence in Japan and Okinawa. He participates in events including the Yōkai Rally and later conflicts like the Jigoku Arc, where he briefly manifests as a vampire-type entity. His combat relies heavily on physical prowess, particularly claw attacks. The 2018 anime introduces Wolfgang (ヴォルフガング), a refined iteration possessing enhanced abilities. He shifts at will between a human-like form—a tan-skinned, suited gentleman sporting a goatee—and a more powerful maroon-furred werewolf state featuring enhanced musculature, a tail, and heightened aggression. This version exhibits regenerative healing negating most injuries except those from silver weapons. His powers intensify under a full moon, granting near-invincibility. Personality-wise, he typically presents as stoic and businesslike, showing deference to superiors like Adél and Backbeard. However, he displays cruel, vengeful tendencies against perceived weaker opponents, evidenced when slaughtering Malaysian yōkai during the Brigadoon Project or taunting Kitarō's allies. His loyalty to the Western Yōkai cause is complicated by personal grievances, such as feeling betrayed by Agnès aiding Kitarō. Wolfgang employs magical stones for combat support, enabling barriers, teleportation, and spell-dispelling. He engages in key battles throughout the 2018 series, including assaults on the GeGeGe Forest and Tokyo, often collaborating with allies like Carmilla and Victor Frankenstein. Following temporary defeats, he consistently regroups with Backbeard's forces, notably aiding in their leader's resurrection during the Nurarihyon Arc. Later narratives reveal familial connections; the fifth anime identifies him as the father of Wild, another werewolf character. This iteration references his involvement in the original Great Yōkai War twelve years prior, including a reunion with Dracula II and Witch to attack Jigoku.
