Monkey D. Luffy
Monkey D. Luffy (モンキー・D・ルフィ Monkī Dī Rufi) is the primary protagonist of the One Piece series. At age seven, he admires and tries to join the pirates of the "Red Haired" Shanks. Ridiculed and rejected, he inadvertently eats their treasure, the Paramecia-type Gum-Gum Fruit (ゴムゴムの実 Gomu Gomu no Mi), which gives his body the properties of rubber. His reckless efforts ultimately lead him into grave peril causing Shanks to lose an arm while rescuing him. After this, Luffy gives up on joining Shanks, resolving instead to start a crew of his own and become King of the Pirates. Displeased by Shanks spoiling his grandson, Garp takes Luffy to be raised by Curly Dadan and her mountain bandits, who he strong-arms into taking him in. During Luffy's time there, he becomes a sworn brother with Garp's other ward Ace, and local runaway noble Sabo. Ten years later, and still wearing Shanks' treasured head covering, Luffy forms and captains his own pirate crew called The Straw Hat Pirates and sets sail for the Grand Line, quickly gaining infamy as "Straw Hat" Luffy (麦わらのルフィ Mugiwara no Rufi). Eventually, after his strength proves insufficient to save Ace from execution, he spends two years on a secluded island, before entering in the New World, learning the use of the three colors of Haki as well as Gear Fourth from Silvers Rayleigh, before heading to the New World. Luffy is voiced by Mayumi Tanaka.
Roronoa Zoro
Roronoa Zoro (ロロノア・ゾロ, named after François l'Olonnais) is a swordsman who uses up to three swords simultaneously, holding one in each hand and a third in his mouth. To fulfill a promise to Kuina, his deceased childhood rival, he aims to replace "Hawk Eye" Mihawk as the world's greatest swordsman. Traveling the seas in search of Mihawk and making a living as a bounty hunter, he becomes infamously known as "Pirate Hunter" Zoro (海賊狩りのゾロ Kaizoku-Gari no Zoro). Eventually, he comes into conflict with Helmeppo. To prevent the harm of innocent civilians, Zoro allows himself to be incarcerated temporarily, while Helmeppo plots to have him killed. Zoro is saved from execution by Luffy in exchange for becoming his first crewman. At that point, Zoro makes it clear that he would turn on his captain if he ever stepped between him and his dream. However, Zoro grows fond of his crew and after several defeats in their defense, his priorities change and he convinces Mihawk to take him on as a student.
Catburgler Nami
Adopted and raised by navy seaman turned tangerine farmer Bellemere, Nami (ナミ) and her older sister Nojiko, witness their mother being murdered by the infamous Arlong, whose pirate gang occupies their island and extracts tribute from the population. Striking a deal with him, Nami, still a child, but already an accomplished cartographer who dreams of drawing a complete map of the world, joins the pirates, hoping to buy freedom for her village eventually. Growing up as a pirate-hating pirate, drawing maps for Arlong, and stealing treasure from other pirates, Nami becomes an excellent burglar, pickpocket, and navigator with an exceptional ability to forecast weather. After Arlong betrays her, and he and his gang are defeated by the Straw Hat Pirates, Nami joins them in pursuit of her dream and acquires infamy herself as "Cat Burglar" Nami (泥棒猫のナミ Dorobō Neko no Nami)
"God" Usopp
During his early childhood, Usopp (ウソップ Usoppu) is abandoned by his father, Yasopp, who leaves to join the Red-Haired Pirates. Then, as Banchina (バンキーナ Bankīna), his mother falls ill, Usopp starts telling tall tales, expressing his hope that his father will return and take them out to sea. Even after his mother dies, Usopp does not blame his father for leaving. Despite his cowardly disposition, he strives to become a great pirate himself. He is a gifted inventor, painter, and sculptor. In combat, he relies primarily on slingshots to fire various kinds of ammunition with great precision. Later in the series, he achieves Observation Haki, while defending his captain. Eventually, he achieves notoriety under his alter-ego "Sniper King the King of Snipers" (狙撃の王様そげキング Sogeki no Ō-sama Sogekingu), a hero sniper wearing a golden mask and cape. Still later in the series he is known as "God" Usopp
Vinsmoke Sanji
While serving as an apprentice cook on a passenger ship, nine-year-old Vinsmoke Sanji (ヴィンスモーク・サンジ Vinsumōku Sanji) stands up to a boarding party of pirates led by the infamous "Red Foot" Zeff (赫足のゼフ Aka-Ashi no Zefu). During the encounter, Sanji is swept into the sea by a massive wave. Zeff jumps in after him because of their common dream of finding the All Blue (オールブルー Ōru Burū), a legendary sea, containing every kind of fish in the world. While castaways together, the pirate saves Sanji's life yet again by giving him all of their food. After their eventual rescue, Sanji stays with Zeff for several years and helps him build a floating restaurant, the Baratie (バラティエ). Zeff in turn makes him a first-rate cook and teaches him his kick-based fighting style. Mirroring Zeff, Sanji will never refuse a starving person a meal, and when fighting only uses his legs, to protect the hands he needs to cook. He also develops an unusual weakness for women, and makes it a principle never to harm one, even if it means his death. Eventually, he becomes infamous under the name of "Black Leg" Sanji (黒脚のサンジ Kuro Ashi no Sanji), and, while training for a period of two years in Emporio Ivankov's Kamabakka Queendom (カマバッカ王国 Kamabakka Ōkoku), develops the Sky Walk (空中歩行 スカイ・ウォーク Sukai Wōku), a variant of the Six Powers (六式 Rokushiki) technique Moonwalk (月歩 Geppo), which allows him to essentially run through air.
Tony Tony Chopper
Tony Tony Chopper (トニートニー・チョッパー Tonī Tonī Choppā) is a doctor and a blue-nosed reindeer. The power of the Zoan-type Human-Human Fruit (ヒトヒトの実 Hito Hito no Mi) provides him with the ability to transform into a full sized reindeer or a reindeer-human hybrid. A self-developed drug he calls Rumble Ball (ランブル・ボール Ranburu Bōru) enables him to perform even more transformations. When complimented, Chopper acts really sad and sometimes yells at the animal who complimented him to stop trying to make him happy
Nico Robin
Growing up in Ohara (オハラ), home of the world's oldest and largest library, Nico Robin (ニコ・ロビン Niko Robin) becomes an archaeologist at the age of eight. At some point she gains the power of the Paramecia-type Flower-Flower Fruit (ハナハナの実 Hana Hana no Mi), which allows her to have temporary copies of parts of her body, including her eyes and ears, which spring up on surfaces near her. Behind her teachers' backs she acquires from them the outlawed knowledge of how to translate the ancient stones called Ponegliffs (歴史の本文 ポーネグリフ Pōnegurifu, alt. Poneglyphs), which are scattered around the world. She comes to share their goal of finding the illusive Real Ponegliff (真の歴史の本文 リオ・ポーネグリフ Rio Pōnegurifu), which is said to tell the world's lost history. However, the World Government finds out about these efforts and sends a battlefleet to stop them. Only Robin escapes the devastating attack that claims the lives of the island's entire population, including that of her mother. Called "Devil Child" (悪魔の子 Akuma no Ko), traumatized, and with a bounty on her head, Robin lives a life on the run, unable to trust anyone. To survive, she cooperates with various pirates and other outlaws, until eventually joining forces with Sir Crocodile, leading Baroque Works with him, using the codename "Ms. All-Sunday" (ミス・オールサンデー Misu Ōrusandē). and becoming their vice-president. After Baroque Works falls apart, with nowhere else to go, she tags along with the Straw Hat Pirates and grows so fond of them that she gives herself up to the Government in order to save them. Only after they discover her motives, and declare open war on her powerful nemesis to get her back, does she come to realize that she has finally found people who will never sell her out, and becomes a part of the crew. After the two-year period where the Straw Hats are separated, Robin further hones her Devil Fruit powers to the point she can create a full-bodied duplicate of herself.
Franky the Cyborg
The son of pirate parents who abandon him at age ten, Cutty Flam (カティ・フラム Kati Furamu), nicknamed Franky (フランキー Furankī), is taken in as an apprentice by a shipwright who secretly holds the plans for a devastating ancient weapon. Franky's recklessness eventually provides an opportunity for World Government agents seeking these plans. Attempting to rescue his master, Franky suffers severe injuries and only survives by rebuilding parts of his body using pieces of scrap metal, turning himself into a cola-powered cyborg with super-human strength. After gaining notoriety as "Cyborg" Franky (サイボーグ フランキー Saibōgu Furankī), and to fulfill his dream of sailing a ship he built around the world, he constructs the Thousand Sunny, a brigantine-rigged sloop-of-war, for the Straw Hat Pirates and joins the crew.
Brook The "Soul King"
Already a pirate before the time of Roger, "Humming" Brook (ブルック Burukku) first enters the Grand Line as vice-captain of the music-themed Rumbar Pirates. Leaving their pet, the infant whale Laboon at Reverse Mountain, they promise to return after sailing around the world. Instead, they are annihilated, with one exception. The power of the Paramecia-type Revive-Revive Fruit (ヨミヨミの実 Yomi Yomi no Mi) allows "Dead Bones" Brook to rise again and live a second life as a skeleton. Fifty years later, Brook's goal is still to fulfill his late crew's promise, and to that end he joins the Straw Hat Pirates. He is an excellent musician, who says that he can play any instrument, although he is usually seen playing the violin. He can even influence people with his music to the point of making them fall asleep. While separated from the other Straw Hats, and incognito as "Soul King" Brook, he gains world fame, filling concert halls with fans. He is also a skilled fencer who uses a shikomizue (a Japanese cane sword) in battle. His reduced weight allows him to jump extraordinarily high and to run across water. Eventually, he learns how to use his devil fruit ability to leave his skeleton body and explore his surroundings as a disembodied soul
"Knight of the Sea" Jinbe
Jinbe is a member of the Straw Hat Pirates, having served predominantly as a helmsman in his current capacity with them. As of now, he is officially the tenth member of the Straw Hat crew and the ninth to join Luffy's crew. He is a whale shark fishman who served as the second captain of the Sun Pirates after Fisher Tiger, and a former Shichibukai from 11 years ago until the Battle of Marineford two years ago. His name was first mentioned by Yosaku, when he was explaining about the Shichibukai. However, he is formally introduced much later, during the Impel Down Arc. He renounced his Shichibukai title at the Battle of Marineford, allying himself with the Whitebeard Pirates. After Whitebeard's death, his crew formed an alliance with Big Mom to protect Fishman Island. He befriended Monkey D. Luffy during the Battle of Marineford, and later allied with him and his crew to prevent the New Fishman Pirates' coup d'état against the Neptune Royal Family and the Ryugu Kingdom. Luffy invited him to join the Straw Hats, but Jinbe held it off until he had severed ties with Big Mom. He would later do so during the Whole Cake Island Arc and officially became a Straw Hat. Jinbe's first bounty was Beli 76,000,000. Eventually, his bounty raised to Beli 250,000,000. After he resigned from the Shichibukai, his bounty has been raised to over Beli 400,000,000.
