Arc 11The Battle of Marineford
Xi Yan helped Luffy and Ace escape the execution, then stayed behind to protect the retreating pirates as Whitebeard fought and died at Marineford. Blackbeard tried to claim Whitebeard’s power, but Shanks arrived and declared that he had come to end the war.
- Xi Yan fought through the Marines while Luffy reached the execution platform, where he freed Ace and escaped with him as Whitebeard ordered his crew to flee.
- Xi Yan clashed with the Admirals, grew his Susanoo, and survived Aokiji’s attempt to freeze him, while Hancock and the Marines failed to stop him.
- When Akainu threatened Luffy and Ace, Xi Yan rescued them and held Akainu back so the pirates could escape, then returned to face the Marines beside Whitebeard.
- Whitebeard fought Akainu and Blackbeard, proclaimed that One Piece was real, and died standing after Blackbeard’s crew attacked him.
- Xi Yan prevented Blackbeard from taking Whitebeard’s body and helped the Whitebeard Pirates escape, then continued fighting Akainu as Koby pleaded for the battle to stop.
- Shanks arrived at Marineford and told Akainu he had come to end the war, while Buggy used Shanks’s reputation to plan a safe departure.
- Shanks asked Xi Yan about Luffy, learned that he was only exhausted, and declined to visit him until Luffy could return the hat.
