Character from One-Punch Man by ONE & Yusuke Murata
S-Class Rank 12 — a man in a dog costume who protects Q-City and Q-City only, with a combat record that terrifies other S-Class heroes and an explanation for none of it.
Watchdog Man is the series' most mysterious active hero. He never leaves Q-City. He defeats every monster that enters Q-City with zero recorded failures. He doesn't attend meetings, doesn't coordinate with other heroes, and the Association has no idea how his powers work. He fought Garou and won effortlessly — one of the only characters to do so. He is a dog-themed enigma and the series has no interest in explaining him.
Wears a full dog costume — a loose-fitting animal onesie with floppy ears and a tail. Sits like a dog. Runs like a dog. Fights like nothing else alive. The costume is silly. The fighting is horrifying.
