Arc 24The Struggle for Pluton
Luffy gained his rubber powers and received Shanks's straw hat before Roy returned to Hachinosu and then uncovered Pluton in Wano Country. Golden Lion and Big Mom attacked to seize the weapon while the Marines waited for an opportunity to destroy it.
- Luffy ate the Devil Fruit, and Shanks lost his left arm rescuing him from the Lord of the Coast before entrusting him with his straw hat.
- Roy gave Ace and Luffy combat knowledge, left Foosha Village with Kuina, and secured her a sword and an apprenticeship under Dracule Mihawk on Hachinosu.
- Roy brought the Pluton blueprints to Wano Country and enlisted Kaido and King to find Tenguyama Hitetsu.
- Roy exposed Tenguyama Hitetsu as Kozuki Sukiyaki, searched his memories for Pluton's location, and killed him.
- Roy recovered a Road Poneglyph rubbing and raised Pluton from its underground dock, but the ship's defenses denied him and Kaido entry while sparing King.
- The Five Elders arranged a Navy operation and leaked the discovery to rival pirates, while Roy summoned Bullet's team aboard the Ark Maxim.
- Roy moved Pluton to Onigashima, organized the Beasts Pirates' defenses, and fought Charlotte Linlin while Kaido battled Golden Lion.
- Roy switched opponents with Kaido and reached a telekinetic stalemate with Golden Lion while Garp, Zephyr, Akainu, Aokiji, and Kizaru watched from a Marine warship.
