One Punch Man Manga Chapter 38
The monster Tongue Stretcher terrorizes civilians until King appears. Merely hearing King’s name causes the creature to surrender without a fight, earning him the crowd’s admiration as Saitama and Genos observe.
Soon after, a robot known as G4 threatens civilians, warning King to fight or face casualties. It is revealed that King is actually an impostor whose fame stems from repeated misunderstandings, prompting him to panic and attempt escape.
Genos confronts G4, telling Saitama to stay back, while Saitama calmly encourages him not to lose. King spends the following week hiding at home playing video games, where Saitama later discovers his cowardice. Meanwhile, Genos continues battling the robot’s true form.
The crisis escalates into a Demon-level disaster when a giant crow attacks King’s apartment building, but Saitama effortlessly stops it with one arm. Genos then begins planning how to capture and study the robot.
