One Piece

One Piece (ワンピース) is a Japanese manga series written and illustrated by Eiichiro Oda. It has been serialized in Shueisha's Weekly Shōnen Jump magazine since July 19, 1997, with the chapters collected into eighty-one tankōbon volumes to date. One Piece follows the adventures of Monkey D. Luffy, a funny young man whose body gained the properties of rubber after unintentionally eating a Devil Fruit. With his diverse crew of pirates, named the Straw Hat Pirates, Luffy explores the grand line in search of the world's ultimate treasure known as "One Piece" in order to become the next King of the Pirates.

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 and has aired 749 episodes to date. Additionally, Toei has developed thirteen animated feature films, two OVAs, and five television specials. Several companies have developed various types of merchandising such as a trading card game, and a large number of 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, before the license was dropped and subsequently acquired by Funimation in 2007.

One Piece has received widespread critical acclaim, primarily for its art, characterization and humor. Several volumes of the manga have broken publishing records, including 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 June 2015, the manga has 320 million copies printed worldwide, making it the best-selling manga series in history.

Setting
The world of One Piece is populated by humans and numerous other races such as "fishmen" (a race of fish/human hybrid, similar to mermen and mermaids), Minkmen (a race of humanoid animals), and giants. It is covered by two vast oceans, which are divided by a massive mountain range called the Red Line, which is also the only continent in the world. The, a sea that runs perpendicular to the Red Line, further divides them into four seas: , , and. Surrounding the Grand Line are two regions called, similar to horse latitudes, which experience almost no wind and ocean currents and are breeding ground for huge sea creatures called. Because of this, the calm belts are very effective barriers for those trying to enter the Grand Line. However, navy ships, members of an intergovernmental organization known as the World Government, are able to use a to mask their presence from the sea kings and can simply pass through the calm belts. All other ships are 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. 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.

The currents and weather on 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 must be used. The Log Pose works 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, a Log Pose variation that is permanently set to a specific island and never changes.

The world of One Piece includes anachronisms, such as the Transponder Snails (電伝虫), snail-like animals that can be attached to electric equipment and function as rotary phones, fax machines, surveillance cameras, and similar devices. , 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.

A is a type of fruit that, which when eaten, confers a power on the consumer. There are three categories of Devil Fruits; fruits allow the user to fully and partially transform into a specific animal; as well as real-life animals. Some Zoan fruits allow the user to transform into mythical creatures. fruits give control over and allow the user "to change their living body structure into the powers of nature". is a category for fruits that give the user superhuman abilities. They 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 of their strength and coordination, although some abilities remain, such as Luffy still being 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 will be reincarnated into a new Devil Fruit. 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.

Haki (覇気) is a latent ability every living being in the world of One Piece possesses, though it is quiescent in most. There are three varieties of Haki: allows to sense the presence of other beings and predict their movement. allows one to envelop body parts and even inanimate forms with a force akin to an invisible armor that possesses defensive and offensive properties, also allowing one to inflict harm upon Devil Fruit users. The rare enables one to intimidate or render beings of weak will power unconscious. Haki is shown that when it's used too much, it will stop working for certain periods of time.

Plot
The series begins with the execution of Gol D. Roger, a man known as the King of the Pirates (海賊王). Just before his death, Roger announces that his treasure, the One Piece, will be available to anyone who finds it, beginning the Great Pirate Era (大海賊時代). As a result, countless pirates set out to the Grand Line to look for the treasure.

Twenty-two years have passed since Roger's execution, and Monkey D. Luffy, a young man inspired by his childhood idol and powerful pirate "Red Haired" Shanks, sets off on a journey from the East Blue sea to find the One Piece and proclaim himself as the King of the Pirates. In an effort to organize his own crew, the Straw Hat Pirates (麦わら海賊団篇), Luffy rescues and befriends a swordsman named Roronoa Zoro, and they head off in search of the One Piece. They are joined by Nami, a navigator and thief; Usopp, a sniper and a liar; and Vinsmoke Sanji, a womanizing chef; in their journey, they acquire a ship named the Going Merry and engage in confrontations with pirates including Buggy the Clown, Captain Kuro and Don Krieg. Later, Luffy encounters Arlong, a fishman and member of the former Sun Pirates who thinks that fishmen are superior to humans. After Luffy defeats Arlong, Nami officially joins Luffy's crew and the Navy places a bounty on Luffy's head. Luffy goes to Loguetown (the town of beginning and end; where Gol D. Roger was born and later executed) then meets Captain Smoker, a Navy captain who can turn into smoke. He briefly captures Luffy, but Luffy is saved by his father, Monkey D. Dragon, who is identified by Smoker simply as Dragon, the most wanted man in the world. After making their way into the Grand Line, the group meets Nefeltari Vivi, a princess who wants to help save her country, the Alabasta Kingdom, from the crime syndicate Baroque Works. They later befriend the doctor and anthropomorphized reindeer Tony Tony Chopper while in Drum Island and along the way fight Baroque Works agents. The Straw Hat Pirates arrive in Alabasta, leading to battles with Baroque Works and their leader, Sir Crocodile a member of the 7 warlords of the sea, who sought to usurp the Alabasta royal line and obtain one of the three ancient weapons, Pluton. Luffy finally defeats Crocodile and liberates Alabasta. Soon after, Nico Robin, an archaeologist formerly employed as Baroque Works vice-president, joins Luffy's crew.

They soon encounter Blackbeard, the alias of Marshall D. Teach, who also aspires to become the King of the Pirates. After traveling to the flying island of Skypiea, the crew gets involved in a war between the Skypieans and the Shandorians, leading to a confrontation against the island's ruler, Eneru, who has the power of lightning. Luffy defeats Eneru to save Skypiea and end the war. The crew soon meets the navy admiral Aokiji, who reveals that Robin was involved in searching for Poneglyphs, which are stones with markings left by an ancient civilization to reveal the missing 100 years of history that the World Government had erased. The group goes to Water 7, where they battle the cyborg shipwright Franky and are informed that the Going Merry is damaged beyond repair, leading to Usopp's temporary departure from the Straw Hat Pirates. However, Cipher Pol No. 9, the World Government's intelligence agency, captures Robin and Franky for information regarding the Poneglyphs and the ancient weapons that may come from them. Franky liberates himself from the government after burning his blueprints for one of the weapons, Pluton, and teams up with the Straw Hat Pirates to declare war on the government, resulting in battles between CP9 and its members. The final long battle with CP9 ends when the crew saves Robin. To replace the sunken Going Merry, Franky constructs a new ship, the Thousand Sunny, for the Straw Hats and officially joins the crew. Soon after, the crew helps a musician skeleton named Brook, who was revived after eating a Devil Fruit, find his shadow aboard the gigantic pirate ship Thriller Bark, which has been stolen by Gecko Moriah. After defeating Moriah, Brook joins Luffy's crew.

After arriving at Sabaody Archipelago, the crew prepares to sail to the New World, the second half of Grand Line. While there, they befriend Silvers Rayleigh, the vice captain of Roger's pirate crew who they ask to coat their ship so they can travel underwater. The crew eventually gets separated during a battle with Bartholomew Kuma, a huge cyborg under the control of the Navy, at the Sabaody Archipelago; Luffy is transported to the all-female island Amazon Lily. Having learned that his adoptive older brother and the son of Gol D. Roger, Portgas D. Ace, has been detained at the government prison Impel Down, Luffy traverses there and liberates several of its prisoners, including the fish man Jimbei and some former enemies. However, Luffy soon learns that Ace is at Marineford to be executed at Navy headquarters. As Luffy arrives, war breaks out between the Navy and a group of pirates led by the legendary pirate Edward Newgate, also known by the alias Whitebeard. In the ensuing chaos, Whitebeard and Ace are killed. At Rayleigh's request, Luffy has his crewmates undergo rigorous training regimens, some under the tutelage of prominent figures.

Two years later, the crew regroups at Sabaody Archipelago and journeys to Fishman Island to enter the New World. During this time, a group of fishman pirates appear, seeking supremacy against humans, and hold a coup d'état to decide the fate of the island. However, after Nami forgives Jimbei for releasing Arlong into the East Blue, the Straw Hats defeat the fishmen pirates, saving the island. The Straw Hats leave Fishman Island and finally reach the New World, though not before starting a feud with Charlotte "Big Mom" Linlin, one of the "Four Emperors", the strongest pirates in the New World. Entering the half-burning and half-freezing island Punk Hazard, the crew encounters an old acquaintance and a recently appointed Warlord, Trafalgar Law, and they form an alliance to take down Kaido, another of the Four Emperors. The alliance is drawn into a fierce battle against Caesar Clown, the scientist responsible for the destruction of Punk Hazard four years earlier, who is in the service of Donquixote Doflamingo.

After Caesar's defeat, the alliance travels to Dressrosa, a kingdom ruled by Doflamingo, in an attempt to destroy the Smile factory, which supplies artificial Devil Fruits to Kaido. In Dressrosa, Luffy competes in a competition to receive the Flame-Flame Fruit, formerly used by Ace. Sanji, Nami, Brook, and Chopper leave Dressrosa when the Big Mom Pirates arrive to attack the Thousand Sunny. Luffy's other adoptive brother, Sabo, arrives and assumes Luffy's place in the competition to earn the Flame-Flame Fruit as Luffy leaves to rescue his friends. Luffy and Trafalgar Law defeat Doflamingo in a battle for Dressrosa's fate and save the country; however, they are forced to flee Dressrosa from naval forces led by Admiral Fujitora to regroup with the others. After escaping and gaining new bounties, seven pirate crews form an alliance and swear their loyalty to Luffy, creating the Straw Hat Grand Fleet.

Luffy, Zoro, Usopp, Robin, Franky, Law, Kin’emon, and Kanjuro head to the mysterious island Zou, which lies on top of a giant elephant named Zunisha, in search for the remaining Straw Hats, the Heart Pirates, Momonosuke, Caesar Clown, and finally the ninja Raizo who was traveling with the samurai. While on Zou, they meet the anthropomorphic animal race known as the Mink Tribe. The crew also discovers that Sanji has suddenly been swept up in a personal conflict, and that Zou has been under siege by Jack of the Beasts Pirates. However, Jack is utterly defeated by Zunisha and peace is restored to Zou. Luffy, accompanied by Nami, Chopper, Brook, and the minks Pekoms, Pedro, and Carrot, heads to Whole Cake Island, where Big Mom resides. They attempt to rescue Sanji from his arranged marriage with Charlotte Purin, one of Big Mom's daughters, which was set up to finalize a political alliance between the Charlotte Family and the Vinsmoke Family.

Production
While working as an assistant to Nobuhiro Watsuki, Oda began writing One Piece in 1996. From there, 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 later appear 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 out the ending, but he found himself enjoying the story too much to and now does not yet intend to end the series. Oda stated that the ending will be what he had decided on from the beginning and 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 and other concepts in the manga 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 a number 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 rendered as demon's cut but may also mean rice ball). 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. The English version of the One Piece manga in many instances 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 drawn by Oda.

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

Manga
Written and illustrated by Eiichiro Oda, One Piece has been serialized in the manga anthology Weekly Shōnen Jump since July 19, 1997. The chapters have been collected into tankōbon volumes by Shueisha since December 24, 1997. In total, there are 830 chapters and 82 tankōbon volumes. Oda teamed up with Akira Toriyama to create a single crossover of 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!!), which 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), written by Ei Andō in a super deformed art syle, 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 chapterwise 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. Following the discontinuation of the print Shonen Jump, Viz began releasing One Piece chapterwise in its digital successor Weekly Shonen Jump on January 30, 2012. In the United Kingdom, the volumes were published by Gollancz Manga, starting March 2006, until Viz Media took it over after the fourteenth volume.

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. It is 29 minutes in length and features character designs by Hisashi Kagawa. 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 get it back. As they fight the pirates, one of them kidnaps Medaka. A fight starts between Luffy and Ganzack, ending in Luffy's capture. Meanwhile, Zoro is forced to give up after a threat is made to kill all of the villagers. The people from the village 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 and 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, but 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 town, defeating a pirate named Crescent Moon Gally on the way. He meets a girl named Silk in town, who was abandoned by attacking pirates as a baby and raised by the mayor, which has caused 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. It 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 exclusive 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 adaptation based on the One Piece manga. The series, which premiered in Japan on Fuji Television on October 20, 1999, has aired more than 700 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 collaborated with Viz Media to distribute the series for home video release and some of their in-house musicians to compose an American background score and theme song. This dub was heavily edited for content, as well as length; the removal and shortening of episodes had reduced the first 143 episodes to 104. Initially, 4Kids originally created an English version of the first opening theme, "We Are!" The series premiered in the United States on September 18, 2004 on the Fox network as part of the Fox Box block, and later aired on Cartoon Network in the Toonami block in April 2005. On December 6, 2006, 4Kids released a statement confirming that it had canceled the project. On July 22, 2010, an interview between Anime News Network and Mark Kirk, the 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 previously 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 on producing One Piece "ruined the company's reputation." Since then, 4Kids established a more strict set of guidelines, checks, and balances to determine which anime the company acquires.

On April 13, 2007, Funimation acquired the license for distribution and started production on an English-language release of One Piece. In an interview with voice actor Christopher Sabat, Sabat 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 producing a new English voice dub, which featured minimal edits compared to the 4Kids dub, the company released its first unedited, 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. The remainder of Funimation's dubbed episodes continued to be aired on Australia's Cartoon Network, and then shifted into reruns before being replaced by Total Drama Island. 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 onwards, will be changed to the 16:9 widescreen format. On May 18, 2013, the uncut series began airing on Adult Swim's revived Toonami block from episode 207 onwards.

Funimation, Toei Animation, Shueisha, and Fuji Television announced in May 2009 that they would simulcast stream the series within an hour of the weekly Japanese broadcast for free. 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 7, 2013, Manga Entertainment announced that it will start releasing the Funimation dub of One Piece in the United Kingdom in 4 disc collection format, starting on May 27, 2013. Crunchyroll began simulcasting the series on November 2, 2013 for the United States, Canada, South Africa, Australia, New Zealand, and Latin America. They started backlogging prior episodes with 25–30 episodes per week starting on March 1, 2014.

Thirteen animated theatrical films based on the One Piece anime series have been released by Toei. The films are traditionally released during the Japanese school spring break since 2000.

Funimation has licensed the eighth, tenth, and twelfth films for release in North America.

The 4Kids English adaptation uses an alternate score as well as its own opening theme.

Manga
One Piece is the best-selling manga series in history; it sold 100 million collected tankōbon volumes by February 2005, over 200 million by February 2011, and had over 380 million volumes in circulation worldwide by 2015. According to Oricon, One Piece has been the best-selling manga series every year since 2008 when the company began its chart. 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.

Additionally, individual volumes of One Piece have broken publishing and sales records in Japan. Volume 56 received the highest initial print run of any manga, 2.85 million copies, in 2009. Volume 57's print of 3 million in 2010 was the highest first print for any book in Japan, not just manga. A record that was broken several times by subsequent volumes and currently held by 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 started 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 ICv2's 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 ICv2's 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".

Allen Divers of Anime News Network comments that the art style One Piece requires "time to get used to" with its "very simple" artwork and its designs, which appear "very cartoonish" at first. 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 creates a "rich tale" without focusing too much on plot. 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. Active Anime describes the artwork in One Piece as "wonderfully quirky and full of expression". Splashcomics comments that Oda's "pleasantly bright and dynamic" ("angenehm hell und dynamisch") art style suits the story's "funny and exciting" (German: "witzigen und ... spannenden") atmosphere.

EX Media lauds Oda's art 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 increasingly. 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."

Anime
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." Margaret Veira of Active Anime praised the TV series' "great" animation, stating that "It gives life and stays true to the style and characters of the manga." and noting the fight scenes in particular as having "a lot of energy to them". Patrick King of Animefringe comments that the art style of One Piece is "very distinctive and fresh".

In a review of the first Funimation DVD release for Mania Entertainment, Bryce Coulter comments that One Piece is "not your typical pirate adventure" and that mixed with "the right amount of random fun along with a shonen style storyline" it becomes "an appealing and fun romp". In a review of Funimation's second DVD release for Mania Entertainment, Bryce Coulter comments that "You can tell that they are giving One Piece the attention that was neglected by 4Kids" and that "One Piece is a great tale of high-seas fun that will leave you wanting more!"
