The Straw Hat Grand Fleet is a fleet formed by seven organizations who vowed to serve under Monkey D. Luffy and the Straw Hat Pirates.
Formed from various powerful crews who managed to succeed in the New World, and the representatives and some other members have been prime contestants of the Corrida Colosseum, the crew is very powerful indeed. In sheer numbers, they have a grand total of 5640 people from various tribes and races, being quite versatile in strength and other attributes.
Five of the seven leaders were powerful enough to defeat executives of the Donquixote Pirates.
Putting the combined known bounties of all of the “Straw Hats” together (both main crew and Grand Fleet) comes to a known total of Over 3,720,000,100 Berries. This places the Grand Fleet as the third highest known group bounty, behind the Big Mom Pirates and the Ninja-Pirate-Mink-Samurai Alliance.
