Straw Hat Grand Fleet

The Straw Hat Grand Fleet is a fleet formed by seven organizations under the command of the Straw Hat Pirates.

Dressrosa Arc
The captains and some members of the Beautiful Pirates, Barto Club, Happo Navy, XXX Gym Martial Arts Alliance (though it had yet to be formed), Giant Warrior Pirates, and the Yonta Maria Grand Fleet fought in the Corrida Colosseum with Luffy. When the Straw Hat Pirates began fighting the Donquixote Pirates, these gladiators assisted him as well as the Tonta Corps. Together, they managed to end the Family's reign.

Three days later, the seven crews assisted the Straw Hat Pirates in escaping from Dressrosa and avoiding capture by the Marines. Once they reached Orlumbus' ship, the Yonta Maria, the captains of each crew asked Luffy if they could drink sake and become subordinates of his.Luffy refused, but said they would still be bonded by their fight against Doflamingo and they would help each other out at anytime. However, the captains decided to drink the sake anyway, pledging to come to Luffy's aid whenever he needed them, while Luffy was not obligated to do the same. The Straw Hat Grand Fleet was then formed, and a party ensued as their fleet departed from Dressrosa.
