The Straw Hat Pirates, also known as the Mugiwara Pirates, Straw Hat Crew, or simply the Straw Hats, are an extremely infamous and powerful pirate crew that originated from the East Blue. They are the main focus and protagonists of the manga and anime One Piece and are led by the main protagonist, Monkey D. Luffy. The "Straw Hats" are named after Luffy's signature hat that was given to him by "Red-Haired" Shanks and are first referred to as the Straw Hat Pirates by Smoker in the Arabasta Kingdom. The crew sailed on the Going Merry, their first official Straw Hat ship, up until the Water 7 Arc. During the Post-Enies Lobby Arc, Franky and Iceburg built them a new ship, which was named the Thousand Sunny by Iceburg, even though the members fought over different names. Following the events on the Sabaody Archipelago, all the members were separated from one another by Bartholomew Kuma, a then-Warlord of the Sea and undercover agent of the Revolutionary Army. For two years, they trained in relatively isolated locations, becoming stronger for the sake of helping each other. They then reunited and have since continued to be a dynamic force in the New World, greatly disrupting the balance of the Three Great Powers. After the Raid on Onigashima, with the defeats of Kaidou and Big Mom, their captain officially became one of the new Four Emperors.The crew currently consists of ten members, being smaller than a typical pirate crew; when he first set sail, Luffy set a goal of gaining ten crewmates. They have one former member, Nefertari Vivi, who sailed with the crew from Reverse Mountain to the Arabasta Kingdom. Despite their small size, the Straw Hats are an extremely diverse group possessing a large variety of backgrounds. Their members' origins range from ordinary islanders and workers to bounty hunters, royalty, criminal gang members, and veteran pirates; Jinbe was once part of the renowned Seven Warlords of the Sea while Robin was an active enemy of the crew at one point with Baroque Works. The crew consists of eight humans, one fish-man, and one animal with Devil Fruit-powered human intellect; of the humans, Sanji possesses superhuman modifications given to him at birth, Franky is a cyborg, and Brook possesses a skeleton body after being resurrected by a Devil Fruit power. They range in age from 17 (Chopper) to 90 (Brook). They first started splitting into teams during the Skypiea Arc. After realizing that the lost city of Gold was on Upper Yard, they split the crew into the Escape Team consisting of Sanji, Nami and Usopp, as well as their patient Gan Fall, and the Search Team which was made up of Luffy, Zoro, Chopper and Robin. The Exploration Team was assigned to find the city and steal the treasure before making it back to the ship, however they ended up getting split up after running into the giant python Nola. The Escape Team were meant to sail the ship to their rendezvous point at the coast, though Sanji and Usopp ended up getting ambushed by Enel, who stopped by to talk to Gan Fall. The ship eventually made it to the coast thanks to Conis and Pagaya, but Nami (along with Aisa who was picked up by the two) was chased away from the ship by Nola. During the Dressrosa Arc, the crew temporarily split in half due to the Big Mom Pirates' unexpected attack on the Thousand Sunny, with one group staying to finish business on Dressrosa and the other heading on to Zou in order to protect Caesar Clown and Kouzuki Momonosuke. The group heading to Zou (Sanji, Nami, Chopper, and Brook) named after Sanji. This same group forms the core of the Sanji Retrieval Team during the Whole Cake Island Arc, but with some personnel changes: Luffy has resumed leadership, Sanji was at Whole Cake Island, and the minks Pedro and Carrot accompanied them in their quest to "retrieve Sanji". During their mission, they were joined by Jinbe who would later officially join the Straw Hats. At the end of the Dressrosa Arc, the crew becomes the leader of an alliance called the Straw Hat Grand Fleet, which involves seven groups who sided with Luffy in the conflict between himself and Doflamingo, becoming subordinate to the Straw Hats, while maintaining their status as individual crews with their own free will. Cavendish, Bartolomeo, Sai, Ideo, Leo, Hajrudin, and Orlumbus asked to become Luffy's subordinates by offering him a cup of sake. Luffy refused but said they would still be bonded by their fight against Doflamingo, and they would help each other out at any time. 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, consisting of 5640 people, was then formed, and a party ensued as their fleet departed from Dressrosa.
