Arc 17Wano, Marineford, and Uta’s Dream
Roy ended the fighting in Wano and returned to Marineford, where his clash with Imu followed the Navy’s defeat of the Holy Knights. He later gave Ace and Teach new powers before the group tried to stop Uta from trapping the world in an endless dream, leaving her song still holding the collapsing dream world together.
- Roy freed Yamato, brought Momonosuke and the Kozuki retainers back to Wano, and refused to choose the country’s ruler as Orochi killed Momonosuke and Sukiyaki before Roy killed Orochi.
- Yamato rejected her Oden persona and vowed to protect Wano as herself while Roy left her to keep order and headed for Marineford.
- Sengoku defeated Saint Saturn, but Saint Garling and Saint Shamrock arrived with the Holy Knights, and Roy intervened before the Marines could clash with them.
- Roy confronted Saint Garling over the attack on his family, but Imu took control of Princess Gunko, overwhelmed the battlefield with Haki, and killed Saturn and Sommers.
- After the Navy restored Marineford, Roy visited Shanks in prison and told him he knew the truth about Elegia before Uta’s concert in Sabaody.
- Roy gave Sengoku the More-More Fruit, gave Ace a ring that intensified his flames, and then gave Teach the Swamp-Swamp Fruit and Gum-Gum Fruit as Teach declared his ambition to become King of the World.
- Uta used her Sing-Sing Fruit to draw concertgoers and people around the world into her dream, while Shanks and Luffy disagreed over whether to stop her.
- Law cut Uta and the space she controlled, breaking apart the dream world, but Uta began humming and pulled the fragments together as Shanks begged her to stop.
