Straw Hat Grand Fleet

The clash with Donquixote Doflamingo on Dressrosa gave rise to this fleet, a body of seven pirate crews that vowed themselves to Monkey D. Luffy. Throughout that fight, a range of crews, independent fighters, and the Tontatta Tribe living on nearby Green Bit had struck alliances of varying firmness with the Straw Hats, all sharing the goal of bringing Doflamingo down after Operation SOP lifted Sugar's toy curse from many of them. With victory won, these assorted parties asked to enroll as proper subordinates sailing beneath the Straw Hats' banner.

Believing that commanding subordinates would cost him his freedom, Luffy declined the offer to accept them. The captains nevertheless drank a reworked sakazuki pledge, swearing to come running whenever he summoned them while placing no matching duty on Luffy, who promised the same aid back to them. Several groups that had not previously been pirate crews reshaped themselves for the moment. Two large forces, the Yonta Maria Grand Fleet along with the Happo Navy, reorganized into crews of their own, the Tontatta members founded the Tontatta Pirates, and four former gladiators, namely Ideo, Abdullah, Jeet, and Blue Gilly, banded into an alliance that later became the Ideo Pirates. Since Luffy now counts as one of the Four Emperors and five of the representatives can defeat Donquixote executives, the fleet rates among the mightiest on the seas, mustering at least 5,640 members apart from the Straw Hats.

Seven captains and their crews form the alliance. Cavendish heads the Beautiful Pirates, Bartolomeo runs the Barto Club, Sai commands the roughly thousand-member Happo Navy, Ideo fronts the Ideo Pirates, Leo leads the Tontatta Pirates, the giant Hajrudin captains the New Giant Warrior Pirates. Rounding out the group, the former adventurer Orlumbus oversees the vast Yonta Maria Grand Fleet. Once they separated at Dressrosa, every captain held on to a fragment of Luffy's Vivre Card and went off on their own cover-story escapades. The fleet's presence contributed to Luffy being acknowledged as an Emperor, and the newspaper afterward dubbed him the Senior Captain and his crewmates the Senior Officers. At the Levely, Sai and Leo stepped in to shield Shirahoshi, while during the Egghead and Elbaph events the Red Hair Pirates tested the Barto Club and then sank the Going Luffy-senpai.
