One Piece characters

One Piece follows Monkey D. Luffy, a boy with a rubber body who sets out to sea to find a legendary treasure and become King of the Pirates. Along the way he gathers the Straw Hat Pirates, a small crew where every member has a personal dream and a job on board: swordsman, navigator, sniper, cook, doctor, archaeologist, shipwright, musician and helmsman. Around them sit three big forces: other pirates (including the Four Emperors and the Seven Warlords of the Sea), the Marines, who hunt anyone sailing outside government law, and the many kingdoms the crew visits, each with its own trouble. This page covers 20 characters: the ten Straw Hats, Luffy's mentor and brother, rivals who keep returning across the story, and the first major villains. Each profile sticks to what you learn when the character is introduced, with no twists revealed.

Protagonist

Monkey D. Luffy モンキー・D・ルフィ

Straw Hat Pirates · Japanese voice: Mayumi Tanaka

Captain of the Straw Hat Pirates and the hero of the story. He ate the Gum-Gum Fruit, so his body stretches like rubber, and almost every attack he uses builds on that. He is reckless, always hungry and trusts his friends completely. His straw hat was a gift from Shanks, the pirate who inspired him as a child, and his goal is to find the One Piece and become King of the Pirates.

Main characters

Roronoa Zoro ロロノア・ゾロ

Straw Hat Pirates · Japanese voice: Kazuya Nakai

Swordsman and the first crewmate Luffy recruits. He fights with three swords, one held in his teeth, and trains constantly. His dream is to become the world's greatest swordsman, which puts Dracule Mihawk squarely in his path. Quiet and blunt, he has a hopeless sense of direction and gets lost all the time, a running joke in the series. He is always first to face danger beside his captain.

Nami ナミ

Straw Hat Pirates · Japanese voice: Akemi Okamura

The crew's navigator. She reads weather and sea currents with rare accuracy and dreams of drawing a complete map of the world. She loves money and tangerines, drives a hard bargain and is often the voice of reason when the boys go too far. In battle she uses a staff that controls the weather. Her bond with the crew grows a lot during the East Blue saga.

Usopp ウソップ

Straw Hat Pirates · Japanese voice: Kappei Yamaguchi

The crew's sniper, from Syrup Village. He is a storyteller who lies out of habit and shakes at the first sign of danger, yet he stands up to much stronger enemies when his friends need him. He fires homemade ammunition from a slingshot and is handy with gadgets. He dreams of becoming a brave warrior of the sea, and many fans see themselves in him.

Sanji サンジ

Straw Hat Pirates · Japanese voice: Hiroaki Hirata

The crew's cook, recruited at the floating restaurant Baratie. He fights only with kicks to protect his hands, which he treats as the tools of his trade. He never lets anyone go hungry, flirts with every woman he meets and argues with Zoro constantly. He dreams of finding the All Blue, a legendary sea said to hold fish from every ocean. He is one of the crew's strongest fighters.

Tony Tony Chopper トニートニー・チョッパー

Straw Hat Pirates · Japanese voice: Ikue Ōtani

The crew's doctor, a reindeer who ate the Human-Human Fruit and gained human speech and shape. He can change size and form, and his self-made Rumble Ball unlocks extra transformations. Naive and shy, he gets flustered by praise and gets angry when people mistake him for a raccoon dog. He joins the crew on Drum Island and wants to become a doctor who can cure any disease.

Nico Robin ニコ・ロビン

Straw Hat Pirates · Japanese voice: Yuriko Yamaguchi

The crew's archaeologist. Calm and observant, she can read the Poneglyphs, stone blocks carved in an ancient script that almost nobody else understands. She ate the Flower-Flower Fruit, which lets her sprout copies of her limbs on any surface. Her sense of humour is dry and a little dark. She first appears during the Alabasta saga and is searching for the history the world tried to erase.

Franky フランキー

Straw Hat Pirates · Japanese voice: Kazuki Yao / Subaru Kimura

The crew's shipwright, a cyborg from Water 7 who rebuilt his own body with weapons and gadgets. Loud, over the top and emotional, he strikes hero poses and cries easily. He built the Thousand Sunny, the ship that carries the crew for the rest of the journey, and keeps everything on board running. His dream is to see that ship sail around the entire world.

Brook ブルック

Straw Hat Pirates · Japanese voice: Chō

The crew's musician, a living skeleton with a huge afro, a top hat and a sword hidden in his cane. He can play any instrument, the violin above all, and makes skeleton jokes nonstop. He is polite and gentle but also a fast swordsman. He joins during the Thriller Bark saga carrying an old promise: to see the whale Laboon again, who has been waiting for him at the entrance to the Grand Line.

Jinbe ジンベエ

Straw Hat Pirates · Japanese voice: Daisuke Gōri / Katsuhisa Hōki

The crew's helmsman, a whale shark fish-man. A master of fish-man karate, he fights by turning the surrounding water into a weapon. Calm, honourable and respected by pirates and sea peoples alike, he was once one of the Seven Warlords of the Sea. Fans see him as the most grown-up member of the crew, the one who thinks before acting and advises Luffy in hard moments. He officially joins much later in the story.

Rivals

Trafalgar Law トラファルガー・ロー

Heart Pirates · Japanese voice: Hiroshi Kamiya

Captain of the Heart Pirates, known as the Surgeon of Death. He ate the Op-Op Fruit, which creates a spherical room where he can cut, swap and rearrange anything inside without real injury. Cold, calculating and quiet, he is one of the rookie pirates who reach the Sabaody Archipelago at the same time as Luffy. Fans love him for his style and his carefully built plans.

Dracule Mihawk ジュラキュール・ミホーク

Seven Warlords of the Sea

Known as the world's greatest swordsman and a member of the Seven Warlords of the Sea. He carries a giant black sword, sails alone in a tiny boat and has hawk-like eyes. He first appears at the Baratie restaurant, where he becomes Zoro's ultimate target: surpassing him is the swordsman's dream. Cold and almost indifferent, he still pays close attention to anyone who shows real potential.

Smoker スモーカー

Marines · Japanese voice: Ginzō Matsuo / Mahito Ōba

A Marine captain stationed in Loguetown, always with two cigars in his mouth. He ate the Smoke-Smoke Fruit, which turns his body into smoke, and carries a jitte tipped with seastone. Stubborn, he chases the Straw Hats into the Grand Line. He does not follow orders blindly and acts on his own sense of justice, which makes him a respected rival rather than a plain villain.

Mentors

Shanks シャンクス

Red Hair Pirates · Japanese voice: Shūichi Ikeda

Captain of the Red Hair Pirates and the man who gave Luffy his dream of becoming a pirate. In the very first episode he loses an arm saving the boy and leaves him the straw hat, on the promise that Luffy will return it once he is a great pirate. Relaxed and fond of a party, he is treated with huge respect across the pirate world and is one of the Four Emperors.

Supporting characters

Portgas D. Ace ポートガス・D・エース

Whitebeard Pirates · Japanese voice: Toshio Furukawa

Luffy's older brother and commander of the 2nd division of the Whitebeard Pirates. He ate the Flame-Flame Fruit, which turns his body into fire. He is polite, protective and has a comic habit of falling asleep in the middle of a meal. He first appears during the Alabasta saga, crossing paths with the crew while he hunts down a pirate who betrayed his own crew.

Boa Hancock ボア・ハンコック

Kuja Pirates · Japanese voice: Kotono Mitsuishi

Empress of the island Amazon Lily, captain of the Kuja Pirates and one of the Seven Warlords of the Sea. She is said to be the most beautiful woman in the world and treats almost everyone with pride and scorn. She ate the Love-Love Fruit, which turns anyone attracted to her into stone. She appears when Luffy lands on her island, a place where men are forbidden.

Koby コビー

Marines · Japanese voice: Mika Doi

A timid boy Luffy meets in the first episode, when he is forced to work for the pirate Alvida. Inspired by Luffy's courage, he joins the Marines to chase his dream of becoming an admiral. The two become friends even though they stand on opposite sides. Koby returns stronger several times across the series and shows that the Marines also have people who truly believe in justice.

Nefertari Vivi ネフェルタリ・ビビ

Alabasta Kingdom · Japanese voice: Misa Watanabe

Princess of the desert kingdom of Alabasta. She went undercover inside a criminal organisation to find out who is pushing her country toward civil war, then asks the Straw Hats for help and travels with them for much of the Alabasta saga. Determined and brave, she would rather risk herself than watch her people suffer. She rides alongside the duck Karoo and is a fan favourite.

Antagonists

Buggy バギー

Buggy Pirates · Japanese voice: Shigeru Chiba

Captain of the Buggy Pirates, a clown with a big red nose who hates any mention of it. He ate the Chop-Chop Fruit, which lets him split his body into pieces and makes him immune to blades. He is one of the first villains Luffy fights, in Orange Town, and keeps coming back throughout the series as comic relief. Long ago he was an apprentice on the same ship as Shanks.

Crocodile クロコダイル

Seven Warlords of the Sea · Japanese voice: Ryūzaburō Ōtomo

One of the Seven Warlords of the Sea, a government-sanctioned pirate who lives in Alabasta and is hailed as a hero by its people. He ate the Sand-Sand Fruit, which turns his body into sand and drains the moisture from anything he touches. He wears a golden hook in place of his left hand and carries himself with cold calculation. He is the main opponent of the Alabasta saga.
