Uchiha Natsu led the Uchiha clan out of Konoha through a Portal after exposing the village’s threat and surviving a coordinated attack. In the New World, the clan began settling on an island while Natsu rescued a merchant ship’s passengers from pirates and learned of the wider world.
Natsu strengthened and organized the Uchiha on Origin Island as their raids drew the attention of the Marines, Blackbeard, and Ace. The arc ended with Gion’s fleet clashing with the island’s defenders as more than a hundred Uchiha reinforcements approached.
The Uchiha Clan fought off the Marines, CP0, and the Blackbeard Pirates as the World Government tried to seize control of Origin Island. Natsu turned the battle in the Uchiha’s favor, but Kizaru arrived and began holding him off while the Marines withdrew.
Natsu drove the Marines from Origin Island and prepared the Uchiha Clan to grow stronger through Haki, while news of his bounty spread across the seas. As the clan’s defenses improved, Natsu prepared to leave, and Ace crossed paths with Luffy while pursuing Teach.
Uchiha Natsu killed Saint Charlos on Sabaody, fought Kizaru, and forced the World Government to raise his bounty and strengthen its defenses. He then took control of Doflamingo and Caesar’s research before beginning to develop a Susanoo-based Sage Mode.
Natsu joined Whitebeard’s campaign to save Ace and restored Whitebeard’s strength with Hashirama Cells. As the battle at Marineford escalated, the Uchiha arrived in force, while Natsu’s whereabouts remained unknown.
Natsu and the Uchiha overwhelmed the Marines at Marineford, but Saint Nerona Imu emerged and fought Natsu with world-shattering force. As the battle erased the island, pirates and Marines fled, and Coby died after being abandoned by a warship.
After the Uchiha Clan rescues the Whitebeard Pirates from Marineford, Natsu recovers from Imu’s attack and reorganizes the clan’s forces. As pirates flood the West Blue, the Uchiha crack down on raiders and prepare a public execution, leaving the region under their control.
Natsu consolidated Uchiha rule in the West Blue, shared the clan’s history and ambitions with Newgate, and strengthened the clan through new traits and training. The arc left the Uchiha expanding their powers and institutions while Natsu entrusted more of the clan’s affairs to its leaders.
Natsu and Izumi traveled to Fish-Man Island, where Natsu freed Shirahoshi, killed pirates, and helped make the island a safer trade hub. Back on Origin Island, the Uchiha expanded Sage Mode through Light of Susanoo before Natsu, Yaoyu, and Yakumi used the Broken Anchor to reach the Ninja World, where they encountered a convoy guarded by Kusagakure shinobi.
Natsu explored Konoha, confronted Hiruzen Sarutobi and Shimura Danzō with the truth of another world, and persuaded Madara to travel with him. At Flame Ninja Village, Madara and Natsu met Uchiha King, whose plans offered the Uchiha a path to survival.
Natsu recruited Madara into the Divine Clan, helped him revive Izuna, and secured Tobirama’s promise to protect the Uchiha. Back in the One Piece world, the Uchiha prepared a new generation for the Grand Line, drawing the attention of the World Government and powerful pirate crews as Chunwu’s squad continued toward Iron Reef Port.
Chunwu’s squad reached the New World, rescued Carlos from Jack, and survived the Beasts Pirates’ attack with Kei’s intervention. News of Kei’s victory prompted the World Government and Marines to monitor and contain the Uchiha, while Madara began recovering on Origin Island.
Madara traveled to Coral Port and defeated Kaido with his Complete Body Susanoo, leaving the Emperor’s fate uncertain. News of the battle alarmed the Marines, Emperors, and World Government, while Imu chose not to activate Uranus against the Uchiha Clan.
Ace reunited with Sabo while Natsu strengthened the Uchiha Clan’s position and received Issho’s pledge to defend the West Blue. The Second Golden Lion confronted the Straw Hat Pirates, leaving them struggling to protect the Thousand Sunny from a boulder assault.
The Straw Hats, Ace, Sabo, the Marines, and rival pirate crews were drawn into a sprawling battle against Second Golden Lion, then the Uchiha Clan entered the fray. Chunwu awakened his Mangekyō Sharingan, while Tetsuka pushed Rin toward the same breakthrough as Yashiro and the Night Owl Guard fought Blackbeard, leaving the battlefield in a tense standoff.
The Uchiha Clan defeated Blackbeard’s crew, forced the Marines to withdraw, and joined Ace, Sabo, and the Straw Hats in a hard-won celebration. The story then shifted to Origin Island, where Sasuke continued training under Natsu’s clone and pushed himself to learn from each defeat.
Sasuke survived a brutal training battle and earned Natsu’s approval as the Uchiha Clan’s growing power unsettled the World Government and Marines. The arc ended with Madara arriving outside Sabaody, where Akainu and the Marines prepared to face the Uchiha warship.
Madara Uchiha confronted the Marines at Sabaody over their plot against his clan, overwhelming their forces until Monkey D. Garp arrived and met him in battle. Their clash devastated the archipelago, prompting Imu to send Saint Saturn, CP0, and the God’s Knights to stop them.
Madara Uchiha fought Garp and the World Government forces at Sabaody, killing Saint Killingham and Saint Saturn before Takamimusubi awakened his power. Imu intervened to stop Madara’s attack, and their first clash devastated the island as the Marines withdrew and prepared to respond.
