One Piece creator Eiichiro Oda finally spilled some of the truth behind Ochoku's disappearance from Hachinosu Island via a summarized exposition in Weekly Shonen Jump. The former Rocks Pirates member had owned the notorious pirate haven for decades after his crew's dissolution at God Valley. Recent story plots have uncovered the identity of his conqueror and the events surrounding this pivotal battle that reshaped the pirate world's power structure.
Marshall D. Teach, known as Blackbeard, defeated Ochoku during the Rocky Port Incident and seized control of Hachinosu Island. This strategic victory allowed Blackbeard to establish his headquarters on the former Rocks Pirates base, marking a crucial step in his rise to Emperor status.
The Rocky Port Incident stands as one of the most consequential events in One Piece history that wasn't straight shown in the manga or anime. This tricky situation entangled multiple key players, each with their own purposes. Trafalgar D. Water Law staged the incident as part of his plan to become a Shichibukai, while Koby earned his "Hero" title by protecting innocent civilians during the chaos.

The incident took place on Hachinosu Island, formerly known as Pirate Island. This zone held special importance as the original base of the Rocks Pirates decades earlier. After the crew's dissolution following the God Valley Incident, Ochoku had taken control of the island and ruled it for years.
Ochoku, also known as Wang Zhi, acted as a prominent member of the Rocks Pirates alongside future Emperors like Whitebeard, Big Mom, and Kaido. When the crew dissolved after their defeat at God Valley, Ochoku decided to claim Hachinosu Island as his territory. Unlike his former crewmates, who sought Emperor status, Ochoku seemed content ruling over this single island.
The former Rocks Pirates member in One Piece maintained control of Hachinosu for several decades following the God Valley Incident. He ruled the island until Blackbeard showed up during the two-year gap. During this time, Ochoku had established a pirate haven where various criminals and outlaws could operate freely.
The Role of Different Key Players During the Rocky Port Incident in One Piece

Blackbeard's defeat of Ochoku wasn't just a random conquest but a deliberate move to launch his own power base. The timing overlapped with his rise to Emperor level, making Hachinosu Island paramount for his ambitions. Blackbeard aspired to create his own pirate paradise, and Ochoku's territory delivered the perfect foundation for this image.
The battle potentially took advantage of the chaos produced by the Rocky Port Incident in the One Piece series. As Law’s plans pulled the Marines toward the island, Blackbeard used the distraction to make his move. The presence of multiple factions during this event may have weakened Ochoku's defenses, allowing Blackbeard to proclaim victory more efficiently.
Marine Captain Koby played a surprising role in the events leading to Ochoku's defeat. Koby showed up at the Rocky Port to protect civilians, but his actions unintentionally helped Blackbeard take control. His bravery during the chaos made him a rising star among the Marines.

Law's involvement as the mastermind behind the Rocky Port Incident also contributed to Ochoku's downfall. His strategic manipulation of events created the perfect storm that allowed Blackbeard to seize control of Hachinosu. Law's plan to become a Shichibukai required demonstrating his capabilities, and orchestrating such a complex incident served his purposes well.
The Aftermath and Consequences of the Incident in One Piece
Following Ochoku's defeat, Blackbeard recast Hachinosu into his personal fortress. The island became the headquarters for the Blackbeard Pirates, functioning as a launching point for their various plans. Taking the island played a big role in Blackbeard being named one of the Four Emperors in One Piece.
The fate of Ochoku himself is still somewhat murky. Even though Blackbeard claimed the island, it’s still unclear if the old member of the Rocks Pirates survived the clash. Some believe he may have been apprehended or killed, while others think he could have escaped to plot his return.
As such, the defeat of Ochoku by Blackbeard during the Rocky Port Incident depicts a climactic moment in One Piece history. While the full facts of their conflict remain wrapped in mystery, the outcomes of this battle continue to influence the current storyline. The complex trap of events surrounding Ochoku's defeat portrays the intricate storytelling of the series.
