One Punch Man Manga Online Chapter 137

Chapter 137 begins with an intense confrontation between Garou and the S-Class heroes. Now in his newly evolved form, Garou radiates monstrous strength and calm confidence. Bang steps up first, hoping to save his former disciple, but Garou effortlessly overwhelms him, using martial arts fused with monstrous speed and power. Bomb intervenes to protect Bang, and together the two brothers manage to hold Garou back momentarily—but it’s clear they’re outmatched. Garou moves with refined aggression, showing that he has not only absorbed monstrous power but also elevated his combat instinct.

Meanwhile, Genos, despite being heavily damaged, attempts to charge in but is held back by others who recognize how dangerous Garou has become. Zombieman, Flashy Flash, and Child Emperor all observe the fight from different vantage points, trying to assess if anyone stands a chance. Just as Garou prepares a devastating finishing blow on Bang, Saitama finally enters the scene—quietly, almost unnoticed. His calm arrival contrasts sharply with the chaos around him. The chapter ends with Saitama locking eyes with Garou for the first time, setting the stage for the much-anticipated showdown between hero and “monster.”
