Arc 18The Summit War
Uchiha Xin reached Marineford and fought Whitebeard, the Marines, and their allies while pursuing his plan to end the chaotic world. After defeating Whitebeard and killing Jozu, he faced Ace, who shielded Whitebeard from Xin’s attack and was left gravely injured.
- Uchiha Xin promised Perona Charlotte Linlin’s Soul-Soul Fruit after the Summit War, then brought her, Tashigi, and twenty Sky Island warriors aboard the Thunder Emperor.
- Z attacked the Thunder Emperor, but Tashigi and Hancock fought him before Uchiha Xin defeated him, and Steel Bone Kong and five CP0 agents then transported Xin to another dimension.
- Uchiha Xin killed the CP0 agents, defeated Steel Bone Kong, learned from his memories about the Clan of D and Uranus, and hurried toward Marineford as the Summit War began.
- Uchiha Xin arrived at Marineford and rejected Whitebeard’s assumption that he had come to help, then declared he would bring the chaotic world to an end.
- Uchiha Xin battled Whitebeard while Hancock, Tashigi, Nami, Perona, and the Thunder Emperor Corps fought the Marines and Whitebeard’s commanders across the battlefield.
- Sengoku proposed that the Marines and Whitebeard Pirates unite against Uchiha Xin, and Garp, Sengoku, and Whitebeard attacked him together without overcoming him.
- Uchiha Xin repelled the three fighters, trapped Sengoku with Wood constructs, and battered Whitebeard until he could no longer stand.
- Jozu rushed to protect Whitebeard, but Uchiha Xin shattered and killed him, extracted his Diamond-Diamond Fruit ability, and declared the fight over, and Ace arrived and was badly injured shielding Whitebeard from Xin’s attacks.
