One Punch Man Manga Online Chapter 13

In Chapter 13, titled “Speed”, the fight between Saitama and Speed-o’-Sound Sonic continues briefly after Sonic is humiliated by a single, accidental hit. Sonic, who prides himself on being the fastest, becomes obsessed with defeating Saitama to restore his honor. Meanwhile, Saitama is more annoyed than impressed, especially since he’s now being mistaken for a criminal due to his bald head, just like the Paradisers. The chapter mixes comedy and action, highlighting the massive gap between Saitama’s strength and everyone else’s perception of him. Sonic flees in shame but vows to return, establishing himself as a recurring rival — even though Saitama doesn’t take him seriously at all.
