The Straw Hat Pirates have the third highest total bounty of any currently known pirate group (Over 1,970,000,100 Berries), behind the Big Mom Pirates and the Ninja-Pirate-Mink-Samurai Alliance.
When Luffy first left his village he mentioned that he would be satisfied with a pirate crew of about 10 crew members.
Two of the Straw Hats are former captains: Brook was the captain of the Rumbar Pirates, and Jinbe was the captain of the Sun Pirates. They were both the crews’ second captains and were assigned the position after the first captain’s demise (Yorki and Tiger respectively).
Every crew members have lost someone whom they loved: Zoro lost his rival and friend, Nami lost her adoptive mother; Usopp lost his mother; Chopper lost his father figure; Robin lost her mother, her civilization, and Jaguar D. Saul; Franky lost his mentor; Brook lost his captain and later on his crew; Luffy lost one of his brothers; and Sanji lost his mother and later his fellow chefs from the Orbit; Jinbe lost his captain, brother, and friend, Fisher Tiger.
The Straw Hats have sailed with at least two royals, Vinsmoke Sanji, the third Prince of the Germa Kingdom and Nefeltari Vivi, the Princess of Alabasta.
The Straw Hats had at least 200,000,000 Berries in their possession, which is the value of the treasure they got from Thriller Bark.
Oda gave information about the sea in which each one of the Straw Hats was born in: Monkey D. Luffy: East Blue, Roronoa Zoro: East Blue, Nami: East Blue, Usopp: East Blue, Sanji: North Blue, Tony Tony Chopper: Grand Line Nico Robin: West Blue, Franky: South Blue, Brook: West Blue, Jinbe: Grand Line.
In the anime since the Post-War Arc, all Luffy, Zoro, Usopp, and Robin’s olive skin were changed to light skin (in Robin’s case to very light skin, similar to Nami’s and Sanji’s) to match them as they are colored in the manga.
Usopp and Sanji are the only Straw Hats who have both of their parents named. They both have a deceased mother (Banchina and Sora), and an infamous father (Yasopp and Judge).
Luffy, Zoro, Usopp, Robin, and Franky all have their own autographs, which they gave to Bartolomeo on his request.
