Fans of "One Piece" certainly know exactly how Roronoa Zoro, the indomitable swordsman, changed so drastically during the two-year timeskip in the series. Zoro lost his left eye as a result of a scar from his own steel.
Before the timeskip, Zoro had both eyes in perfect condition. However, when the Straw Hat Pirates reassembled after two years, we learned that Zoro already had a characteristic scar running down his left eye and kept it permanently closed.
This revelation immediately led to speculation and debate among the "One Piece" fandom. Yet no matter how hard anybody tries, the details of Zoro's eye-losing experience have always been stretching to seem curiously nebulous.
There is no clear explanation for this in the film or the TV series itself. Fans end by speculating that Zoro probably lost the eye while training with Dracule Mihawk during the two-year break. Also known as "the world's greatest swordsman," Mihawk is a very experienced male practitioner of black magic, observe fans.
Zoro was likely in some kind of training or massive brawl when he had his eye gouged out.
However, this event has not been explained or showed up in the series yet, and Zoro keeping one of his eyes shut will remain as an unanswered question for the time being.
Creator Eiichiro Oda has never been too eager to provide a full explanation about just how or why Zoro got his scar, the mysterious closed eye.
The lack of deficiencies or specific missing motifs gives the initiated another magnificent tension waiting to be unfolded. Despite all the questions and theory, meanwhile, fans eagerly anticipate an episode throughout the future or some revelation that will appear in manga form.
