One Punch Man Manga Online Chapter 138

Chapter 138 kicks off the long-awaited face-off between Saitama and Garou. The surrounding heroes, battered and exhausted, look on anxiously as the two stand across from each other—Saitama calm and unimpressed, Garou exuding intense bloodlust. Garou launches the first attack, unleashing a flurry of monstrous punches and shockwaves. But Saitama, as always, effortlessly dodges or takes the hits without flinching.

Garou grows more agitated, pushing his limits further, blending martial arts with monstrous instinct in increasingly unpredictable ways. His strikes crack the ground and distort the air, but Saitama remains largely unmoved, only speaking in his usual deadpan way: confused why Garou is even fighting him. Meanwhile, the other heroes are stunned, realizing the power gap is on a different level. Flashy Flash in particular begins to suspect Saitama is far stronger than anyone knew. As Garou grows more desperate, his form begins to shift again—hinting at a deeper, more terrifying evolution still underway. The chapter ends with a dramatic standoff: Saitama finally getting serious (slightly), and Garou preparing for one more overwhelming strike—one that could push him beyond the point of no return.
