The Zoro Fan Theory That Changes Everything On One Piece
With One Piece approaching its 22 year anniversary and its 1000th episode, fans of the long-running anime have certainly been through a lot with Monkey D. Luffy and the Straw Hat pirates, and yet fans are currently being treated to perhaps one of the most eventful story arcs the series has ever offered. The Wano Country arc is in full swing, as Luffy and the Straw Hats fight to liberate Wano Country from its merciless Shogun and the Beast Pirates led by Kaido. Even as the conflict in Wano is heating up, creator Eiichiro Oda has promised that the arc is leading into the "Biggest War" in series history – greater than anything we've seen to date.
As such, the fast approaching end of this arc will be incredibly important to the story moving forward, and fans speculate that one part of Wano Country's climactic finale will be a shocking revelation about a longtime character's origins.
Zoro's mysterious backstory
Roronoa Zora is one of a only a few characters who has been around since the anime's beginning. The second member ever to join the Straw Hat Pirates, Zoro is first mate to Luffy and one of his most loyal companions, and yet throughout the story there has been little to no information given about his origin or backstory. The theory suggests that Zoro's origins are actually from Wano, and that very soon we'll get a reveal about his parents and identity before his time as a Pirate. The anime revealed that before the Shogun took over Wano, the Shimotsuki clan ruled the eastern part of the island, and it just so happens that the village in East Blue that Zoro claims to be from is named Shimotsuki.
In addition, the sword-obsessed samurai culture of Wano seems a perfect fit for Zoro, one of the series most prolific swordsman (and in fact he poses as a Ronin early on when they arrive at the island). The circumstances of Zoro's departure from Wano are unknown at this time, but any connection could have massive implications for Wano Country's role in the massive war to come.
