One Piece Film Z

The film opens with a man singing "Ocean Guide". "Black Arm" Zephyr (黒腕のゼファー, Kokuwan no Zefā), a former naval admiral and leader of the Neo Marines which also includes his henchmen Ain (アイン) and Binz (ビンズ, Binzu), commences an assault on the navy on Firs Island, a volcanic island and one of the End Points. While there, Zephyr steals the Dyna Stones and fights Kizaru and the marines before he starts an eruption to defeat the Admiral only to be sent flying into the ocean. While having a cherry blossom party, the Straw Hat Pirates discover an unconscious Zephyr floating on the sea. Luffy uses his gum gum devil fruit ability to reel him in, but when grabbing Zephyr’s prosthetic arm (the battle smasher) Luffy loses all his strength. The Straw hats soon learn that Zephyr’s arm is made with sea prism stones. As Chopper begins to attend to Zephyr’s wounds, Nami begins to worry, not just because of the prosthetic arm, but also because of Zephyr’s muscular form and his many battle scars, but Luffy reassures Nami that if Zephyr is a threat he will deal with him. When Zephyr comes too, everything is fine at first as Luffy and Zephyr begin socialising, but when Zephyr learns that Monkey D. Luffy is a pirate, he fights Luffy, Roronoa Zoro and Sanji. Having discovered Zephyr's location with a Vivre Card, Ain and Binz join the ex-Admiral to fight them. Ain uses her Devil Fruit powers to de-age Nami, Tony Tony Chopper, Brook and Nico Robin, while Binz uses his Devil Fruit powers to trap Franky, Usopp and Brook with vines. Luffy goes one on one against Zephyr, but is overpowered and defeated when Zephyr grabs Luffy with his Battle Smasher arm. Realising that Luffy is the grandson of Monkey D. Garp, Zephyr attempts to kill them, but the Straw Hats are forced to flee. At Marine Headquarters, the navy discovers Zephyr's whereabouts and decide to recover the Dyna Stones.
