One Piece Chapter 16, page 11-15: VERSUS BUGGY'S CREW!

Zoro stands panting heavily inside the thick dust cloud. Cabaji strikes from the blindness, clashing blades with Zoro before executing a swift follow-up maneuver that catches Zoro off guard.

Cabaji lands a harsh kick directly onto Zoro's bleeding wound, sending him crashing to the ground. Nami screams in horror as Zoro collapses, while Cabaji mockingly questions what kind of man screams like a woman.

Cabaji boasts over the fallen Zoro, declaring that this defeat will teach him not to mess with Buggy's crew. Nami frantically begs Luffy to intervene, but Luffy remains quiet. Cabaji raises his sword to deliver a finishing blow.

Zoro suddenly blocks Cabaji's final strike, shocking the acrobat. Luffy cheers while Nami looks on in disbelief. Zoro slowly stands up, panting heavily, and tells Cabaji that he hopes he enjoyed kicking his wound while he had the chance.

To everyone's absolute horror, Zoro deliberately stabs his own wound deeper, causing blood to spray. Cabaji, Nami, Buggy, and Luffy stare in shock as Zoro intentionally handicaps himself.
