Garou is a villain, a martial arts prodigy, the self-proclaimed “Hero Hunter,” and a major adversary of the Hero Association and Monster Association. He is a former disciple of Bang but was expelled from his dojo for going on a rampage. Because of his fascination with monsters, he is commonly called the “Human Monster.” Sitch of the Hero Association views him as a grave threat to the organization despite being only a human.

Garou is a young man with sharp features, yellow eyes, and long silver hair that spikes upward in two large prongs, giving a feeling of a young wolf. He has a lean muscular build. He wears a tight, black, long-sleeved shirt, loose-fitting white martial arts pants, a yellow sash around his waist, and tai chi slippers on his feet.
