One Piece (Universe)

One Piece (ワンピース, Wan Pīsu) is a Japanese manga series written and illustrated by Eiichiro Oda. This Japanese manga series has been serialized in Shueisha's Weekly Shōnen Jump magazine since July 22, 1997, and has been collected into 90 tankōbon volumes. The story follows the adventures of Monkey D. Luffy, a boy whose body have gained the properties of rubber after unintentionally eating a Devil Fruit known as the Gum-Gum Fruit. To fulfill his dreams of being a great pirate, Luffy explores the seas in search for the world's ultimate treasure of Gol D. Roger - known as "One Piece", located in the Grand Line - in order to become the next King of the Pirates. With his motley crew of pirates, named the Straw Hat Pirates, they travel the world to make their dreams come true.

The manga has been adapted into an original video animation (OVA) produced by Production I.G in 1998, and an anime series produced by Toei Animation, which began broadcasting in Japan in 1999. Additionally, Toei has developed thirteen animated feature films, one OVA and eleven television specials. Several companies have developed various types of merchandising such as a trading card game and numerous video games. The manga series was licensed for an English language release in North America and the United Kingdom by Viz Media and in Australia by Madman Entertainment. The anime series was licensed by 4Kids Entertainment for an English-language release in North America in 2004, before the license was dropped and subsequently acquired by FUNimation in 2007.

One Piece has received praise for its storytelling, art, characterization, and humor. Several volumes of the manga have broken publishing records, including the highest initial print run of any book in Japan. The official website for Eiichiro Oda's One Piece manga announced that the manga has set a Guinness World Record for "the most copies published for the same comic book series by a single author". As of May 2018, the manga has sold over 440 million copies worldwide, making it the best-selling manga series in history. It became the best-selling manga for the tenth consecutive year in 2017.

The series focuses on Monkey D. Luffy, a young man who, inspired by his childhood idol and powerful pirate "Red Haired" Shanks, sets off on a journey from the East Blue Sea to find the famed treasure One Piece and proclaim himself as the King of the Pirates. In an effort to organize his own pirate crew, the Straw Hat Pirates (麦わら海賊団篇, Mugiwara Kaizoku-danhen), Luffy rescues and befriends a swordsman named Roronoa Zoro, and they head off in search of the One Piece. They are joined in their journey by Nami, a navigator and thief; Usopp, a sniper and a liar; and Sanji, a womanizing chef. They acquire a ship named the Going Merry and engage in confrontations with notorious pirates of the East Blue. As Luffy and his crew set out on their adventures, others join the crew later in the series, including Tony Tony Chopper, a doctor and anthropomorphized reindeer; Nico Robin, an archaeologist and former assassin; Franky, a cyborg shipwright; Brook, a skeletal musician; and Jimbei, a fish-man helmsman; and they also acquire a new ship named the Thousand Sunny.

Setting
The world of One Piece is populated by humans and many other races such as "fishmen" (a race of fish/human hybrids, similar to mermen and mermaid), dwarves, Minks (a race of humanoid animals), and giants. It is covered by two vast oceans, which are been divided by a massive mountain range called the Red Line (レッドライン, Reddo Rain), which is also the only known continent in the world. The Grand Line (グランドライン, Gurando Rain), serves as a sea that runs perpendicular to the Red Line, the further divides them into four different seas: North Blue (ノースブルー, Nōsu Burū), East Blue (イーストブルー, Īsuto Burū), West Blue (ウェストブルー, Uesuto Burū) and South Blue (サウスブルー. Sausu Burū). Surrounding the Grand Line are two regions are called Calm Belts (カームベルト, Kāmu Beruto), similar to horse latitudes, which experience almost no wind or ocean currents and are the breeding ground for huge sea creatures called sea kings (海王類, Kaiōrui; lit. "sea kings"). Because of this, the calm belts are very effective barriers for those trying to enter the Grand Line. However, marine ships, and other members of an intergovernmental organization known as the World Government, are able to use a Sea-Prism Stone (海楼石, Kairōseki) to mask their presence from the sea kings and can simply pass through the calm belts. All the other ships are been forced to take a more dangerous route, going through a mountain at the first intersection of the Grand Line and the Red Line, a canal system known as Reverse Mountain (リヴァース・マウンテン, Rivāsu Maunten). Sea water from each of the four seas runs up that mountain and merges at the top to flow down a fifth canal and into the first half of the Grand Line. The second half of the Grand Line, beyond the second intersection with the Red Line, is known as the New World (新世界, Shin Sekai).

The currents and weather of the Grand Line's open sea are extremely unpredictable, whereas in the vicinity of islands the climate is stable. The magnetic fields within the Grand Line cause normal compasses to malfunction, making it even more difficult to navigate, and instead a special compass called a Log Pose (ログポース, Rogu Pōsu) must be used. The Log Pose functions by locking on to one island's magnetic field and then locking on to another island's magnetic field. The time for it to set depends on the island. This process can be bypassed by obtaining an Eternal Pose (エターナルポース, Etānaru Pōsu), a Log Pose variation that is permanently set to a specific island and never changes.

The world of One Piece also includes anachronisms, such as the Transponder Snails (電伝虫, Den-Den Mushi; literally meaning "Electric Transmission Bug"), snail-like animals that can be attached to electric equipment and function as rotary phones, fax machines, surveillance cameras, and similar devices. Dials (ダイアル, Daiaru), the shells of certain sky-dwelling animals, can be used to store kinetic energy, wind, sound, images, heat, and the like and have various applications.

Devil Fruits

 * Main article: Devil Fruits

Devil Fruits (悪魔の実, Akuma no Mi; literally meaning "Fruit of the Devil") are types of fruit that, when eaten, grants a power to the eater. A person may only eat one Devil Fruit during their lifetime, as eating a second devil fruit will swiftly end their life. Devil Fruits are said to be incarnations of the sea devil himself, and as a result, Devil Fruit users cannot swim in sea water, as "they are hated by the sea". Sea-Prism Stone also has this effect. When even partially submerged in sea water, they lose all their strength and coordination, although some abilities remain. For example, Luffy is still able to stretch after being totally submerged. Moving water, such as rain or waves, does not have this effect. When a Devil Fruit user dies, the powers reincarnate into a new Devil Fruit. For unknown reasons, Devil Fruit users cannot eat a second Devil Fruit because it would cause their bodies to burst, although Blackbeard managed to get a second Devil Fruit power through an unknown method. Devil Fruit powers can be in a stage called "Awakened", where the user can turn anything around them, besides their own bodies, into what their Devil Fruit power is. There are only three categories of Devil Fruits;
 * Paramecia (パラミシア, Paramishia; literally meaning "superhuman type") is a category of fruits that give the user superhuman abilities.
 * Zoan (ゾオン, Zoon literally meaning "animal type") fruits allow the user to fully or partially transform into a specific animal. As well as real-life animals, some Zoan fruits allow the user to transform into mythical creatures.
 * Logia ロギア, Rogia; literally meaning "nature type") fruits give control over, and allow the user "to change their living body structure into the powers of nature".

Haki

 * Main article: Haki

Haki (覇気; lit. "Ambition") is a latent ability that every living being in the world of One Piece possesses; very few manage to awaken it, and even fewer master it. It is shown that when it is used too much Haki will stop working for certain periods of time, so it can't be in use constantly.

There are three varieties of Haki:
 * Observation Haki (見聞色の覇気, Kenbunshoku no Haki; literally meaning "Haki of the Color of Observation") allows one to sense the presence of other beings and to have a form of limited precognition. (This is a great advantage in combat because the user can foresee his opponent's attacks).
 * Armament Haki (武装色の覇気, Busōshoku no Haki; literally meaning "Haki of the Color of Armaments") allows one to envelop body parts and even inanimate forms with a force akin to an invisible armor that possesses defensive and offensive properties. It also allows one to inflict harm upon Devil Fruit users.
 * Conqueror's Haki (覇王色の覇気, Haōshoku no Haki; literally meaning "Haki of the Color of the Supreme Ruler") is a rare ability that, unlike the other two Haki, only a few gifted people have. (If a person is not gifted, then no matter how much they train they will never be able to use it). The Conqueror's Haki enables one to overpower the will of the weak-willed. It can be used to mind-control or even render the victim unconscious. Note that strong willed people can withstand, or even completely ignore, the effects of this Haki, even if they do not possess this ability themselves. This Haki can also have physical impacts, such as causing tremors and destruction to the user's surrounding area.

Production
While working as an assistant to Nobuhiro Watsuki, Oda began writing One Piece in 1996. It started as two one-shot stories entitled Romance Dawn—which would later be used as the title for One Piece's first chapter and volume. They both featured the character of Luffy, and included elements that would appear later in the main series. The first of these short stories was published in August 1996 in Akamaru Jump and later in One Piece Red. The second was published in the 41st issue of Weekly Shōnen Jump in 1996, and reprinted in 1998 in Oda's short story collection, Wanted!.

Oda revealed that he originally planned One Piece to last five years, and that he had already planned the ending. However, he found it would take longer than he had expected. Oda stated that the ending would be what he had decided in the beginning; he is committed to seeing it through.

When creating a Devil Fruit, Oda thinks of something that would fulfill a human desire; he added that he does not see why he would draw a Devil Fruit unless the fruit's appearance would entice one to eat it. The names of many special attacks, as well as other concepts in the manga series, consist of a form of punning in which phrases written in kanji are paired with an idiosyncratic reading. The names of Luffy, Sanji, Chopper, Robin, and Franky's techniques are often mixed with other languages, and the names of several of Zoro's sword techniques are designed as jokes; some of them look fearsome when read by sight but sound like kinds of food when read aloud. For example, Zoro's signature move is Onigiri, which is written as demon cut but is pronounced the same as rice ball in Japanese. Eisaku Inoue, the animation director, has said that the creators did not use these kanji readings in the anime since they "might have cut down the laughs by about half". Nevertheless, Konosuke Uda, the director, said that he believes that the creators "made the anime pretty close to the manga".

Oda was "sensitive" about how his work would be translated. In many instances, the English version of the One Piece manga uses one onomatopoeia for multiple onomatopoeia used in the Japanese version. For instance, "saaa" (the sound of light rain, close to a mist) and "zaaa" (the sound of pouring rain) are both translated as "fshhhhhhh". Unlike other manga artists, Oda draws everything that moves himself to create a consistent look while leaving his staff to draw the backgrounds based on sketches he has drawn.

When a reader asked Oda who Nami is in love with, he answered that there will not likely be any references to romance, since he believes the series' intended demographic is not interested.

The chapters have been collected into tankōbon volumes by Shueisha since December 24, 1997. In total, there are 914 chapters and 89 tankōbon volumes. Oda teamed up with Akira Toriyama to create a single crossover of oda's One Piece and Toriyama's Dragon Ball. Entitled Cross Epoch, the one-shot was published in the December 25, 2006, issue of Weekly Shōnen Jump and the April 2011 issue of the English Shonen Jump. Oda collaborated with Mitsutoshi Shimabukuro, author of Toriko, for a crossover one-shot of their series titled Taste of the Devil Fruit (実食! 悪魔の実!!, Jitsushoku! Akuma no Mi!!, lit. "The True Food! Fruit of the Devil!!"), which first ran in the April 4, 2011, issue of Weekly Shōnen Jump. The spinoff series One Piece Party (ワンピースパーティー, Wan Pīsu Pātī), written by Ei Andō in a super deformed art style, began serialization in the January 2015 issue of Saikyō Jump.

The One Piece manga was licensed for an English language release by Viz Media, who published it via chapters in the manga anthology Shonen Jump, since the magazine's launch in November 2002, and in bound volumes since June 30, 2003. In 2009, Viz announced the release of five volumes per month during the first half of 2010 to catch up with the serialization in Japan.

Festival films and original video animation
''One Piece: Defeat Him! The Pirate Ganzack!'' was produced by Production I.G for the 1998 Jump Super Anime Tour and was directed by Gorō Taniguchi. Luffy, Nami, and Zoro are attacked by a sea monster that destroys their boat and separates them. Luffy is found on an island beach, where he saves a little girl, Medaka, from two pirates. All the villagers, including Medaka's father have been abducted by Ganzack and his crew and forced into labor. After hearing that Ganzack also stole all the food, Luffy and Zoro rush out to retrieve it. As they fight the pirates, one of them kidnaps Medaka. A fight starts between Luffy and Ganzack, ending with Luffy's capture. Meanwhile, Zoro is forced to give up after a threat is made to kill all the villagers. They rise up against Ganzack, and while the islanders and pirates fight, Nami unlocks the three captives. Ganzack defeats the rebellion and reveals his armored battleship. The Straw Hat Pirates are forced to fight Ganzack once more to prevent him from destroying the island.

A second film, One Piece: Romance Dawn Story, was produced by Toei Animation in July 2008 for the Jump Super Anime Tour. It is 34 minutes in length and based on the first version of Romance Dawn. It includes the Straw Hat Pirates up to Brook and their second ship, the Thousand Sunny. In search for food for his crew, Luffy arrives at a port after defeating a pirate named Crescent Moon Gally on the way. There he meets a girl named Silk, who was abandoned by attacking pirates as a baby and raised by the mayor. Her upbringing causes her to value the town as her "treasure". The villagers mistake Luffy for Gally and capture him just as the real Gally returns. Gally throws Luffy in the water and plans to destroy the town, but Silk saves him and Luffy pursues Gally. His crew arrives to help him, and with their help he recovers the treasure for the town, acquires food, and destroys Gally's ship.

The film was later released as a triple feature DVD with ''Dragon Ball: Yo! Son Goku and His Friends Return!! and Tegami Bachi: Light and Blue Night'', that was available only though a mail-in offer exclusively to Japanese residents.

The One Piece Film Strong World: Episode 0 original video animation adapts the manga's special "Chapter 0", which shows how things were before and after the death of Roger. It received a limited release of three thousand DVDs as a collaboration with the House Foods brand.

Anime series

Toei Animation produces an anime television series based on the One Piece manga. The series, which premiered in Japan on Fuji Television on October 20, 1999, has aired more than 800 episodes, and has been exported to various countries around the world. Two cross-over episodes with the anime adaptation of Toriko were aired. The first of these, which was also the first episode of Toriko, aired on April 3, 2011. A second special, which also crossed over with Dragon Ball Z, aired on April 7, 2013.

On June 8, 2004, 4Kids Entertainment acquired the license for distribution of One Piece in North America. 4Kids contracted Viz Media to handle home video distribution. 4Kids' in-house musicians wrote a new background score and theme song nicknamed "Pirate Rap". 4Kids' dub mandated edits for content and length, which reduced the first 143 episodes into 104. Initially, 4Kids originally created an English version of the first opening theme, "We Are!" It premiered in the United States on September 18, 2004, in first-run syndication on the Fox network as part of the weekend programming block Fox Box, and later aired on Cartoon Network on their weekday afternoon programming block Toonami in April 2005. Production was halted in 2006 after episode 143/104. Viz also ceased its home video release of the series after volume 11. On July 22, 2010, an interview with Anime News Network and Mark Kirk, senior vice-president of digital media for 4Kids Entertainment, revealed that 4Kids acquired One Piece as part of a package deal with other anime, and that the company did not screen the series before licensing it. However, once 4Kids realized One Piece was not appropriate for their intended demographic, the company decided to edit it into a more child-oriented series until they had an opportunity to legally drop the license. Kirk said the experience of producing One Piece "ruined the company's reputation". Since then, 4Kids established a stricter set of guidelines, checks, and balances to determine which anime the company acquires.

On April 13, 2007, Funimation licensed the series and started production on an English-language release of One Piece. In an interview with voice actor Christopher Sabat, he stated that Funimation had been interested in acquiring One Piece from the very beginning, and produced a "test episode," in which Sabat portrayed the character of Helmeppo and Eric Vale played the part of the main character, Monkey D. Luffy. (They would later go on to provide the English voices for Roronoa Zoro and Sanji, respectively.) After resuming production of the renewed English dub, which featured less censorship because of fewer restrictions on cable programming, Funimation released its first uncut, bilingual DVD box set containing 13 episodes on May 27, 2008. Similarly sized sets followed with fourteen sets released. The Funimation-dubbed episodes premiered on Cartoon Network on September 29, 2007 and aired until its removal on March 22, 2008. On October 28, 2011, Funimation posted a press release on their official website confirming the acquisition of episodes 206–263, and the aspect ratio, beginning with episode 207, would be changed to the 16:9 widescreen format. On May 18, 2013, the uncut series began airing on Adult Swim's revived Toonami late-night programming block from episode 207 onward. One Piece was removed from the Toonami block after March 18, 2017.

In May 2009, Funimation, Toei Animation, Shueisha, and Fuji Television announced they would simulcast stream the series within an hour of the weekly Japanese broadcast at no charge. Originally scheduled to begin on May 30, 2009, with episode 403, a lack of security resulted in a leak of the episode, and Funimation delayed the offer until episode 415 on August 29, 2009.

On February 12, 2013, it was announced that Manga Entertainment would also start on releasing the Funimation dub of One Piece in the United Kingdom in a DVD box set format. Crunchyroll began simulcasting the series on November 2, 2013, for the United States, Canada, South Africa, Australia, New Zealand, and Latin America.

Theatrical films

 * Main article: List of One Piece films

Thirteen animated theatrical films based on the One Piece series have been released in Japan. The films are typically released in March in accordance with the spring vacation of Japanese schools. The films feature self-contained, completely original plots, or alternate retellings of story arcs with animation of a higher quality than what the weekly anime allows. The first three films were typically double features paired up with other anime films, and were thus, usually an hour or less in length. The films themselves offer contradictions in both chronology and design that make them incompatible with a single continuity. Funimation has licensed the eighth, tenth, and twelfth films for release in North America, and these films have received in-house dubs by the company.

Video games

One Piece is the first-ever manga series to hold a "Dome Tour", in which events were held from March 25 to 27 at the Kyocera Dome in Osaka, and from April 27 to May 1 at the Tokyo Dome. In 2014, the first One Piece exhibition in Korea was held at the War Memorial of Korea, and the second exhibition in Hongik Daehango Art Center. In the year 2015, a One Piece trompe-l'œil exhibition was held at the Hong Kong 3D Museum.

Live-action series
On July 21, 2017, Weekly Shōnen Jump editor-in-chief Hiroyuki Nakano announced that Tomorrow Studios (a partnership between Marty Adelstein and ITV Studios) and Shueisha would commence production of an American live-action television adaptation of Eiichiro Oda's One Piece manga series as part of the series' 20th anniversary celebrations. Eiichiro Oda will serve as executive producer for the series alongside Tomorrow Studios CEO Adelstein and Becky Clements. The series will reportedly begin with the East Blue arc.

Manga
One Piece is highly one of the most best-selling manga series in history; it sold 100 million collected tankōbon manga volumes by February 2005, and over 200 million by February 2011, before selling over 365 million copies sold in Japan and 440 million copies worldwide as of May 2018. According to Oricon, One Piece has been the best-selling manga series every year since 2008 when the company began its manga chart, and it became the best-selling manga for the tenth consecutive year in 2017. Due to promotions for the Strong World film, all 56 volumes of the manga released at the time charted on Oricon's list of the top 200 manga for the week of December 7–13, 2009. Up until February 2012, One Piece had grossed at least ¥112,126,800,000 ($1,404,220,000) in manga tankōbon sales revenue.

Additionally, individual volumes of One Piece have broken publishing and sales records in Japan. In 2009, Volume 56 had the highest initial print run of any manga: 2.85 million copies. Volume 57's print run of 3 million copies in 2010 was the highest first print for any book of any subject in Japan—a record that was broken several times by subsequent volumes and currently held by Volume 67's 4.05 million initial printing in 2012. Volume 60 was the first book to sell over two million copies in its opening week on Oricon book rankings, and later became the first book to sell over three million copies since the chart began in 2008.

One Piece has also sold well in North America, charting on Publishers Weekly's list of bestselling comics for April/May 2007 and numerous times on The New York Times Manga Best Seller list. On ICv2s list of Top 25 Manga Properties Fall 2008 for North America, which is compiled by interviews with retailers and distributors, Nielsen BookScan's Top 20 Lists of graphic novels and ICv2s own analysis of information provided by Diamond Comic Distributors, One Piece came in 15th place. It rose to second place on their Top 25 Manga Properties Q3 2010 list.

Allen Divers of Anime News Network comments in 2003 that the art style One Piece employs "initially seems very cartoonish with much of the character designs showing more North American influence than that from its Japanese origins". Adding that the "artwork and settings come across as timeless in their presentation". He also notes that the influence of Akira Toriyama (Dragon Ball) shines through in Oda's style of writing with its "huge epic battles punctuated by a lot of humor" and that, in One Piece, he "manages to share a rich tale without getting bogged down by overly complicated plots". Rebecca Silverman of the same site stated that one of the series' strengths is to "blend action, humor, and heavy fare together" and praised the art, but stated that the panels could get too crowded for easy reading. The website activeAnime describes the artwork in One Piece as "wonderfully quirky and full of expression". Splashcomics comments that Oda's "pleasantly bright and dynamic" (German: "angenehm hell und dynamisch") art style suits the story's "funny and exciting" (German: "witzigen und ... spannenden") atmosphere.

EX Media lauds Oda's art just for its "crispy" monochrome pictures, "great use of subtle shade changes" on color pages, "sometimes exquisite" use of angles, and for its consistency. Shaenon K. Garrity, who at some point edited the series for English Shonen Jump, said that, while doing so, her amazement over Oda's craft grew steadily. She states that "he has a natural, playful mastery of the often restrictive weekly-manga format," notes that "interesting things [are] going on deep in the narrative structure," and recommends "sticking through to the later volumes to see just how crazy and Peter Max-y the art gets". Mania Entertainment writer Jarred Pine comments that "One Piece is a fun adventure story, with an ensemble cast that is continuing to develop, with great action and character drama." He praised Oda's artwork as "imaginative and creative" and comments that "Oda's imagination just oozes all of the panels [sic]". He also notes that "Oda's panel work [...] features a lot of interesting perspectives and direction, especially during the explosive action sequences which are always a blast," though he complains that the panels can sometimes get "a little chaotic".

Anime
The anime adaptations have also been very well-received. The first episode of the anime adaptation earned a viewer ratings percentage the rate of 12.4, behind Pokémon and ahead of Ojamajo Doremi. As of the year 2017, One Piece is among the top 10 anime in viewer ratings every week in Japan. On several occasions the One Piece anime has topped Japan's DVD sales.

In a review of the second DVD release of 4Kids Entertainment's dub, Todd Douglass, Jr. of DVD Talk called its adaptation a "shabby treatment" resulting in an "arguably less enjoyable rendition". Douglass said that the 4Kids original opening was "a crappy rap song" and that the removal of whole scenes leaves a "feeling that something is missing". He later went on to say that "Fans of the 'real' One Piece will want to skip picking [...] up [4Kids Entertainment's One Piece DVDs] until an uncut release is announced", and also stated that "kids may get into this version because it's what they have seen on TV".
