Nami - A beauty

"Cat Burglar" Nami is a pirate and the navigator of the Straw Hat Pirates. She was the third member of the crew and the second to join, doing so during the Orange Town Arc. Later she betrayed the crew during the Baratie arc, but rejoined at the end of the Arlong Park Arc, after her past and her intention were revealed.

She is introduced as a thief and pickpocket who possesses skills to tell the climate and draw sea charts. At first, she is a subordinate of the fishman Arlong, but she is eventually freed of this service and permanently joins Monkey D. Luffy for her dream to write the complete map of the Grand Line.

Nami is depicted as an intelligent girl who has an obsession of obtaining money. She is able to use her three-sectioned staff and use her climate skills to create powerful attacks; the most prominent of these staff weapons is the Clima-Tact, in which she manipulates the climate to create weather-based attacks.

Black Leg Sanji

"Black Leg" Sanji  is the Straw Hat Pirates' cook. He knows how it feels to starve from first hand experience, so he will never refuse someone a meal. He has a strong sense of chivalry, because of which, he will never harm a woman, even if he dies. Sanji also seems to keep this code regardless of a woman's appearance. His dream is to find the "All Blue" a legendary sea, containing every kind of fish in the world. Sanji only uses kicks while fighting. He said that this is because a chef's hands are his most prized possessions and should not be risked in battle. Sanji begins using a fire-based kick technique known as Diable Jambe (devil leg)  in which he heats his leg by spinning around rapidly to increase his attack power.

He is the one of the most powerful crew member of "Straw Hat Pirates". He flirts with every lady. He usually gets into argument with Roronoa Zoro.

Roronoa Zoro

He is one of the two swordsmen of the Straw Hat Pirates, the other being Brook. In the story, Zoro is the first to join Monkey D. Luffy after he is saved from being executed at the Marine Base. As a native to the East Blue, he came from the town known as Shimotsuki where he trained in a dojo. He is an expert swordsman who uses three swords for his Santōryū (Three Sword Style), but is also capable of the one and two-sword styles.

Unarguably an extremely powerful and strong young fighter with immense potential, Zoro is one of the Straw Hat Pirates's top three fighters, and his strength is considered so great that, when taking his stern personality into account, people occasionally mistake him as the captain of the Straw Hat Crew after witnessing his skills in battle. While Luffy always fights the strongest enemy, Zoro usually fights the second strongest enemy.

Zoro is confident, but often acts in a very comical manner. He also has a terrible sense of direction which he is very insecure about since he never admits it when he gets lost, instead he always blames someone else. While the crew is out at sea, Zoro can be found (usually) sleeping or training towards his goal of becoming the world's best swordsman. He and Sanji have a great rivalry, often resorting to fighting (both verbally and physically) over issues from minor to extreme.

He was formally a bounty hunters who hunted pirates for bounty.

He can cut through extremely large objects with incredible ease, speed, and precision (also considering without the use of his left eye). Zoro was even able to cut a Pacifista in half with just one slash from his swords, where as two years prior he barely managed to only slightly damage one.

Shanks and Red Hair Pirates

Just like Straw Hat pirates.. this is also a group of good pirates.
Shanks always wears a long black cape over his shoulders and, until he met Luffy, he wore a straw hat obtained from his captain.
Shanks is one of the most laid back characters in the world of One Piece, preferring to take his time as he and his crew travels around the world rather than rushing from one place to another. His friendly nature means he will not purposely seek to harm others, and he is able to make serious characters like Dracule Mihawk join in with his fun. Yet despite how simple minded he appears at first, Shanks is a complex person with some rather difficult to understand views.

He lost his hand while saving Luffy from a sea monster. At that time luffy was just a child. Shanks saw the potential of luffy and provided him his most valuable straw hat which he inheritted from his captain Gol D. Roger.

Red Hair Pirates under the captaincy of Shanks is one of the strongest pirate crew in the new world. They are ne of the four emperors of the sea. The pirate crew also have a great snipper Yasopp who is the father of Ussop (sniper of Straw hat pirates).

It was Shank who came in the end to finally put an end to the fight between Whitebeard Pirates and Marines in Marineford. He inspired Luffy to become a pirate.

STRAW HATS

The Straw Hat Pirates are a pirate crew that originated from East Blue, but have various members from different areas. They are the main focus and protagonists of the anime and manga 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 byRed-Haired Shanks,captain of Red-haired Pirates.

and are first referred to as the Straw Hat Pirates by Smoker in Alabasta. The crew sailed on the Going Merry, their first official Straw Hat ship, up until the Water 7 Arc. After the Enies Lobby Arc, they obtain a new ship called theThousand Sunny. The Straw Hats currently consist of nine members whose combined bounties equal 800,000,050.

Following the events on the Sabaody Archipelago, all nine members were separated from one another. For two years, they trained in relatively isolated locations, becoming stronger for the sake of helping each other.
