As the higher-ups of the Hero Association discuss the status of various cities, Watchdog Man was mentioned, as the hero in charge of Q-City. His report states "All quiet here". The suits are concerned about Watchdog Man's attitude, but admit that he can handle the dangerous city.
Watchdog Man made a brief appearance at the S-Class meeting. At the meeting, he comments that they, the heroes, cannot prevent the prophecy from happening.
Garou finds Watchdog Man relaxing in the Watchdog Man Plaza. Before he can attack, an invasion from the Monster Association arrives at the plaza. Watchdog Man quickly dispatches all of the monsters and rips them apart with great haste, while Garou observes him. Garou then attempts to attack Watchdog Man while the hero is sitting. Watchdog Man dodges the attack and asks Garou, if he is a human or a monster.
Watchdog Man then engages in battle with Garou. Unfortunately for Garou, Watchdog Man is shown to be far superior to him in speed and strength, and because his technique was like that of a wild animal rather than a human being, Garou was unable to properly read his movements and was ultimately forced to retreat, even after Garou used his most powerful technique: the Water Stream Rock Smashing Fist. All the while, his face remained stoic and emotionless.
