One Punch Man Manga Chapter 171 Summary

The Ultimate Clash Begins

Chapter 171 of the One Punch Man manga takes readers deeper into one of the most intense battles of the series, blending raw emotion, cosmic power, and shocking twists. This chapter highlights the dangerous evolution of Garou, the struggles of the Hero Association, and the long-awaited emotional turning point for Saitama. Let’s break down the key events and themes from this unforgettable installment of the superhero manga.

Heroes on the Brink of Collapse

The chapter opens with a dire scene: Child Emperor and Waganma suddenly collapse, bleeding from their noses. Zombieman and Sekingar rush to help, only to notice Child Emperor’s hair falling out—a sign of the devastating radiation pouring off Garou’s body.

Meanwhile, Bang (Silver Fang) confronts his former student, urging Garou to abandon his dark path. But Garou insists he’s acting by his own free will, setting up a heartbreaking master-versus-student standoff.

Blast Arrives: A Cosmic Warning

The tension skyrockets when Blast, the mysterious S-Class Rank 1 hero, emerges through a portal. Wasting no time, he warns Garou that he’s being manipulated by “God,” and that his unleashed power could annihilate life on Earth.

Despite Blast’s attempt at reason, Garou mocks the situation, embracing his role as humanity’s “Ominous Future” and declaring himself a Disaster Level: God. His arrogance and newfound abilities force Blast to take action.

The Battle of Dimensions: Blast vs. Garou

What follows is one of the most visually spectacular fights in the One Punch Man manga:

• Garou’s cosmic radiation incapacitates nearly every hero nearby.
• Blast retaliates with Dimension Cannon and Gravity Knuckle, trapping Garou in a loop of portals.
• In a shocking twist, Garou copies Blast’s techniques, launching his own Nuclear Fission: Gravity Knuckle, a move so destructive Blast must divert it skyward to save the planet.

Despite Blast’s mastery, Garou makes it clear—his true rival isn’t Blast. It’s Saitama.

Genos’s Sacrifice

As chaos unfolds, Genos refuses to stand down. Using the last of his strength, he charges at Garou, proving his loyalty to Saitama. But tragedy strikes—Garou seizes Genos and fatally impales him, ripping out his core.

This moment marks a turning point. Genos’s fall isn’t just a loss for the heroes—it becomes the emotional spark that ignites Saitama’s fury.

Saitama’s Return and The Serious Punch Showdown

As black rain falls, Saitama finally reappears. His arrival is too late to save Genos, and for one of the rare times in the series, we see him truly shaken. When Garou hurls Genos’s broken core at him, Saitama catches it silently—his grief transforming into rage.

At last, the Hero Hunter meets the full force of Saitama’s resolve. The chapter ends with both warriors unleashing Serious Punches—Garou now able to mimic Saitama’s power in his new “Mode: Saitama.” The clash is so massive that even Blast fears it could obliterate the Earth itself.

Final Thoughts on Chapter 171

Chapter 171 is more than just a battle—it’s a turning point in the One Punch Man manga. Themes of mentorship, sacrifice, and destiny collide as Garou’s corruption reaches its peak and Saitama’s long-suppressed emotions finally surface.

For fans of superhero manga, this chapter delivers everything: heartbreaking sacrifices, jaw-dropping action, and the promise of an earth-shattering conclusion.
