Roronoa Zoro
Occupation: Swordsman
Status: Alive
Age:19 (pre-timeskip) 21 (post-timeskip)
Birthday: November 11th
Height: 5'11(1/4)
Description: Zoro was the first person Luffy recruited to be part of his crew after rescuing the swordsman from being captured by the government. Ever since then, Zoro has followed his captain, eventually becoming extremely loyal and trusting of Luffy's decisions. They both have respect for each other's abilities and know what the other is capable of. However, they can easily press each other's buttons and get frustrated with the other. Zoro is a master fighter with his blades and knows when to pick his spots, while Luffy wants to march in and hit people, a dynamic that doesn't usually mesh well together. With all their squabbling and frustration, they are loyal to each other and have each other's back.
Nami
Occupation: Navigator
Status: Alive
Age:18 (pre-timeskip) 20 (post-timeskip)
Birthday: July 3rd
Height: 5'7
Description: Nami was the second person recruited to Luffy's ship and became the navigator. Although she was using Luffy at first for her own means, Luffy considered her a friend, and when the flighty girl took off to settle her debts, he helped her gain her freedom and she came aboard his ship again. Like most of the others who are part of the Straw Hat pirates, Nami gets flustered with Luffy rather easily. Nami usually has to yell at him to get him to do much of anything on the ship, and yells at him some more when he screws up any of their plans or just does something stupid. But, just like the others on his crew, she considers him a friend and will help him as much as she can. Likewise, Luffy will do anything for her if she gets into trouble, which tends to happen a lot as she tries to acquire more money and treasure for herself or the crew (usually herself). Although he cares for her very much, it's strictly platonic as he doesn't really seem interested in a romantic relationship.
Usopp
Occupation: Sniper
Status: Alive
Age:17 (pre-timeskip) 19 (post-timeskip)
Birthday: April 1st
Height: 5'9(1/4)
Description: The notorious fibber joined Luffy and the crew after they landed on his island and helped Usopp and his friend Taya. Usopp is the son of Yasopp, the marksman on Shanks crew Luffy grew up with. Usopp's cowardice and preference for the safest way often conflicts with Luffy's sense of adventure. They disagree on a lot of things, the worst instance being when Usopp left Luffy's crew for a while after a disagreement over the fate of their first ship, the Going Merry when they reached Water 7. However, after saving Robin from the Marines at Enis Lobby, Usopp wants to join back up with Luffy, who was all for it. Aside from these disagreements, they get along very well, with Usopp telling his tall tales and Luffy excitedly believing every word of it.
Vinsmoke Sanji
Occupation: Cook
Status: Alive
Age:19 (pre-timeskip) 21 (post-timeskip)
Birthday: March 2nd
Height: 5'11
Description: A relationship of supply and demand. Sanji the cook supplies good food for Luffy's crew and Luffy demands more of it, whether he actually likes the dish or not. Sanji is constantly frustrated with his captain's bottomless pit of a stomach and constant begging for food. He also isn't afraid of punishing Luffy by giving him scraps or not feeding him at all. But, even after all the squabbles, Sanji still has respect for Luffy as not only the captain of the Straw Hat Pirates but as a friend as well. Although he refused at first, by joining Luffy, Sanji was able to travel the world and see things he would never have seen staying at the floating restaurant that Luffy found him in. His quest to go to the All Blue was all but a pipe dream until Luffy came along. Despite being at each other's throats at times, they are good friends and will stand back to back in a fight if need be to get the job done.
Tony Tony Chopper
Occupation: Doctor
Status: Alive
Age:15 (pre-timeskip) 17 (post-timeskip)
Birthday: December 24th
Height: 2'11(1/2)
Description: Luffy and the little reindeer medic who ate the Hit Hito no Mi(Human Human Fruit)have a little brother/older brother type relationship. Chopper idolizes Luffy for being the brave pirate captain and hangs on to his every word. Although early in their relationship Luffy thought of Chopper as a food source, The Captain soon recognized Chopper's skill as a medic and made him a part of his crew. Chopper has saved Luffy's life a number of times and likewise Luffy has saved Chopper from some really bad situations. Although they sometimes squabble, usually if Luffy is being overly rough with an injured patient, they don't fight nearly as much as Luffy does with Nami or Zoro. Chopper thinks the world of his captain and Luffy thinks the same of his medic.
Nico Robin

Description: Robin originally started out as an enemy of Luffy and his crew. Known as 'Miss Sunday' she was a part of the Baroque Works organization and worked for its leader Crocodile. When Crocodile turned on her and left her to die in collapsing ruins, Luffy saved her from certain death. She then joined the crew out of respect for Luffy saving her, as well as a way out of Baroque Works. Although he was skeptical at first, Luffy grew to trust Robin and think of her as a friend. Robin seems to be the only crew member that Luffy doesn't squabble with. Be it her calm demeanor, or a high tolerance for Luffy's shenanigans, they don't get on each other's nerves. Out of all of Luffy's crew, She is able to explain things to Luffy without the Captain screaming at her. Even when he is told of Robin's past and how much trouble she can be to any crew she joins, Luffy doesn't care and thinks of her as a friend first.

When they return and are recovering, Franky volunteers to build them a new ship since the Going Merry was no longer useable. Franky becomes part of the crew as the boatwright.
