The World Government is either a necessary evil that in order to maintain order in a world populated by criminals with insane powers and monster strength has to Shoot the Dog more times than it would like or is a hopelessly corrupt organization that hides its flagrant abuse of power behind the pretense of justice for the sake of maintaining the status quo. Even Oda can't seem to make up his mind on the matter.
Americans Hate Tingle: In Japanese polls, the princess characters are popular in their home country, but they are widely disliked in the West (particularly Shirahoshi and Rebecca).
Arc Fatigue: Possibly the series' Achilles' Heel, with readers noting its tendency to add too many elements in its arcs, causing them to last very long.
While the Summit War Saga (Sabaody Archipelago until the Time Skip) is generally well liked, the rest of the Straw Hats are Put on a Bus for over three quarters of it. By the end, many fans just wanted to see the crew together again. The marineford arc was also heavily criticized during its run for many repetitive moments that didn't serve any purpose except pad out the arc.
In the anime, the show's slower pacing could seriously be felt during Marineford. Particularly, the large string of episodes where it felt like Luffy was forever running across the ice trying to reach the platform where Ace was being held captive.
Skypiea is a very long Story Arc and has relatively low stakes due to feeling disconnected from the rest of the setting.
Oda's love of multi-chapter flashbacks, Loads and Loads of Characters, Call Backs, and all tropes Chekhov come to a head at Dressrosa. To wit: 2 and a half years in real life spent on the same island, about 10 individual flashbacks (though most are connected, making them easy to follow), a little over 50 named new characters, the reintroduction of several old characters, and 102 chapters of contentnote This makes it the third-longest arc in the series after Wano and Water 7-Enies Lobby. The anime is even longer, with 118 episodes aired in total, 16 more episodes than there were chapters (that's what using about 1/3 to 1/2 of one chapter's content for each episode will do).
The Kozuki Oden flashback during the Wano arc's third act ran a whopping 14 chapters (by far the longest in the series). While it was generally liked and well received, to the point it's considered one of the peaks of the series writing-wise, some fans wanted for it to end and get back to present Wano for the war.
Archive Panic: As of January 2021 the manga has reached over 1000 chapters, with no end in sight. Viz Media put out omnibuses that collect three volumes each, but not only do they have lower quality paper than the single volumes, even if you're willing to look past that, it's still difficult to catch up even with them.
Ass Pull: While Oda tends to properly foreshadow most plot twists, there are a few instances of this.
The most infamous is the classic "Pell surviving a city-destroying bomb with absolutely no justification."
Less infamous, but perhaps even more blatant — Pagaya, a completely untrained civilian, survives Enel's Bolt of Divine Retribution with nary a scratch when even Made of Iron badasses like Zoro and Wiper were left half-dead from it.
The Straw Hats suddenly getting various upgrades during the Enies Lobby arc. Nami unveils a Perfect Clima Tact on the sea train, mentioning that Usopp gave it to her before he left, despite using her normal Clima Tact at the Galley-La Mansion. Usopp unveils his Kabuto when sniping the World Government flag, despite having used his normal slingshot on the sea train. Worst of all is Zoro's Ashura form, which rarely appears since then and wasn't explained until Wano.
In the anime fillers, Luffy's defeat of Don Achino was easily this because Don Achino had the power to generate craptons of heat, enough to take casual lava baths. In the final moments of the fight he tries to ram right into Luffy, who grabs him with his bare hands, shouts a few times, and throws him across the battlefield, ultimately suffering only a few minor burns from the ordeal.
During the Marineford Arc Galdino managing somehow to disguise as a guard and reach the platform, all under Sengoku's nose, despite the latter being, supposedly, a great strategist and therefore should have everything in check. It's all revealed at the last minute only to give Luffy a new key for Ace's handcuffs.
Shanks' arrival at Marineford. Just before the battle, Shanks is stated to be in an encounter with Kaido, yet he manages to arrive just in time to end the war and prevent the Marines from killing all of the pirates, who have lost the war. This event has been harshly criticized as one of Oda's worst cop outs.
Pudding's story: her maliciousness is the result of bullying over said third eye from her childhood came off as sudden and forced. Big Mom in particular has been characterized as a Collector of the Strange who found a living skeleton absolutely adorable and has been shown to have conversations with Pudding while the eye was exposed without mentioning it, and was stated by Pudding herself (at a point when she had no reason to be lying) to be overbearingly affectionate to her, making her disgust toward her daughter's third eye especially jarring.
Bege and Chiffon's cover story reveals Pound inexplicably survived retribution from a pissed-off Oven, who'd seemingly killed him with a Gory Discretion Shot and just so happens to drift to Dressrosa to meet his two daughters.
Chapter 1030 reveals that Kin'emon survived being run through by Kaido, supposedly because his torso and legs were never properly reattached after Law cut him in half on Punk Hazard. Nothing similar happened to any of the other people Law dismembered with his powers.
When he started the series, Oda had concerns that the series' unusual, cartoony art style might turn away potential readers. While many consider it one of the series' selling points, there are indeed some people who consider the art style a turnoff.
Concerning the television run of the show in America, the English dub got heavily delayed, switched hands between 4Kids (who severely edited it from the original per Toei's demands) and FUNimation (who started with a watershed-friendly TV-PG edit before gaining the rights to fully dub the whole series from the top with TV-14 content) in a messy and lengthy contract dispute that stalled out the release of a faithful dubbed version, and fell very behind the Japanese releases of new episodes, and the series never got to air in complete form on American television. When it came back on Toonami, it started in an odd place because they had no access to the episodes before the switch to high-definition (up to the Skypiea Arc, virtually all of which were in dispute with 4Kids until it went bankrupt in 2012), so they began broadcasting the Long Ring Long Land Arc (repeatedly cited to comprise a Breather Episode in arc form that is often balked at as a feeble moment of/entry point into the series for being too comedy-driven instead of plot-driven), nowhere near the most recent point of the series, while the majority of the series's more dedicated viewers were far, far ahead. This ultimately killed its chances to pull in sufficient ratings and got it jolted off the block after the Thriller Bark Saga concluded.
The princesses post-Vivi were all criticized for being naive, whiny loads and Ms. Fanservice taken too far. The princess of the Wano arc, Hiyori aka Komurasaki dresses conservatively despite being the equivalent of a High-Class Call Girl. She's also One Piece's best Heroic Seductress, taking down an arsonist's ring with nothing but her beauty and feminine wiles. A far cry from the likes of Shirahoshi and Rebecca.
Following some criticism for the handling of Ivankov and the okamas, particularly the repeated insistence from other characters that they "aren't real women", the reveal that O-Kiku in the Wano arc is a trans woman is a welcome change. The fact that the story never treats her as anything less than a real woman, and the fact that she's both badass and stereotype-defying has led to her becoming one of the Wano arc's most popular characters.
Awesome Art: While the art quality per se has been quite inconsistent, especially in later chapters as Oda's health declined, the panels where he shows off the absurd and creative places the Straw Hats visit fits perfectely with the series's cartoony style and are filled with details. Since the beginning, Oda has consistently received praise from critics for his paneling skills and the ability to make the pages enjoyable to read, being regarded as one of the best in the industry in that field.
Usopp. Some like the angle Oda intended on making Usopp a relatively normal character in terms of strength who often has to use his wits to pull a victory, while others view him a nuisance for his cowardice and dead weight. This reached a head during the Water 7 arc, in which he temporarily parts ways with the crew out of a refusal to accept that the Going Merry is beyond saving. Some were sympathetic to his attachment, while others viewed him as an idiot who the crew would have been better off without.
There's quite a bit of controversy surrounding how Pudding was handled. While her reception was fine even after she dipped into a Hate Sink following the reveal of her true colors, the issues start at the wedding. Sanji, unable to keep his lust down even for a woman he knows is eager to kill him, blurts out a compliment toward her Third Eye once he finally sees it, pacifying Pudding due to her Freudian Excuse regarding the discrimination she's suffered for it. For some (see Jerkass Woobie below), this redeemed Pudding and gave her even more depths. For others, the Freudian Excuse feels too sudden and contrived (especially regarding the criticism her eye apparently got from Big Mom, which is extremely out of character given her established love of her exotic and lifelong goal of creating a discrimination-free utopia) and simply allowed Sanji to dance around the lesson of being too weak-willed around pretty women, while for others it allowed to show the positive of Sanji's chivalrous personality. Others in that camp argued that the twist ruined what would have been a fascinating villain. Her later Tsundere characterization is either hilarious, or a waste of time during the final period of the arc.
One Piece is a manga planned more with a volume basis than with a weekly basis, resulting in some arcs appearing to be too long and dragged out if read chapter by chapter every week. However, many fans say that, if read in its entirety, the pacing problems are absent. This results in many arcs to be re-evaluated much more positively after a complete read.
The anime has over 900 episodes as of this writing, and the manga has over 1000 chapters so far. With the manga, you can easily get the volumes to read at your own pace, but the anime has long arcs, some of them filler, that started off with adapting the chapters at a good pace, but after a while has resorted to adapting either one chapter per episode, or less than even that, so knocking out dozens of episodes by binging the show is the best way to watch it, especially when Oda loves to use Continuity Porn, Continuity Nods, and likes to bring back older characters after they previously appeared in earlier arcs. It's much more rewarding to binge the show in short bursts than it is to watch week to week.
Near the climax of the Alabasta arc, a group of soldiers known as the Kicking Claw Squad (who'd never been mentioned before) show up to fight Crocodile. They then reveal that they drank the "hero water" (which also had never been mentioned before), which increases their strength at the cost of eventually killing them. Crocodile simply flies to a safe place and waits for them to die. Neither the scene nor the Kicking Claw Squad are ever mentioned again.
The Davy Back fight that takes place between the Skypiea and Water 7 arcs is this. The battle against the Foxy Pirates has left no impact whatsoever on later events, and Foxy only ever reappears in irrelevant Filler. This is a case where Tropes Are Not Bad, however, since the arc was short and served as a Breather Episode between Skypeia (which was fairly long) and Water 7 (one of the most intense, dark, and emotional arcs in the series).
The magnificently bizarre "EVERYBODY! ZOMBIE NIGHT!" scene, where a bunch of zombies from Thriller Bark break into dance.
In Marineford, many scenes happen without consequences, like Sengoku rolling up one of his sleeves, ready to fight, only in the next scene to be still on the platform with the sleeve back down, or Garp sitting on the Admiral's Throne, which is treated like a big moment, only to leave no impact. This causes most of these moments to appear silly rather than epic.
Most One Piece fans were able to correctly deduce that the Soldier toy was Rebecca's father given the scenes they were shown together in before the reveal.
Many One Piece theorists and readers were convinced that Lola is one of Big Mom's daughters long before her parentage was explored in full, because Oda didn't try to hide it and even hinted at her "mama" being a very powerful pirate as in Big Mom.
From pretty much the moment she was introduced fans easily deduced that Komurasaki was actually Hiyori because in the very next scene Momo talks about his sisters, making it pretty easy to connect the dots. At the same time, though less so, many correctly guessed that Kyoshiro is actually Denjiro thanks in part to the Anime Opening giving a visual clue, spoilingeven the manga readers.
Many fans believe that the Grand Line splits the One Piece world in two horizontally like an equator, while the Red Line, perpendicular to it, is vertical. In truth, as shown in some maps or when the moon's hump changes side between some arcs, they both cross the world diagonally. This is why the Blue Seas are named after the cardinal directions.
A minor case is with fans to consider Elbaf an island while in-universe it has always been referred to as a village or a kingdom.
Though fans continue to refer to her as such, Kaya is not Usopp's childhood friend. Usopp himself says he's only been speaking to her for about a year, shortly after her parents died - technically speaking Kuro has known her longer.
Continuity Lockout: So very, very much. It is a true test of character to try to describe the series to a person who has never heard of it. It's especially one of the reasons why the 4Kids dub is despised since the dub had a tenancy to skip entire story arcs, creating a lot of continuity-related plot holes.
Luffy. Sailing up a geyser and once absorbing a hundred souls (when most badasses can only hold two or three), are some of his saner plans.
Franky. Take a guy, dress him up in a Hawaiian shirt and speedo, then watch as Oda consistently (and successfully) challenges himself to make that the least bizarre thing about him.
Brook's first appearance convinced Luffy this guy needs to be brought into his crew, due to this.
Kaido also deserves special mention. His debut involves him climbing up to Sky Island and fricking BODY SLAMMING his way down to the earth. He doesn't do this to attack, mind you, he does this to see if he can handle it.
Creator Worship: Eiichiro Oda has been mentioned at least three times on this site as being awesome, crazy prepared and an author who never forgets. Fans also deem him the "Jesus" of Shonen (when Akira Toriyama is the "God"). Oda himself acknowledged this: In one SBS, when one fan asks him what his greatest treasure is, he answers "of course, it's ALL YOU READERS."
If the fanart is any indication, the Vinsmoke boys (other than Sanji, of course) have been getting this treatment from some fangirls (no doubt due to their appearance).
To a lesser extent, almost all of CP9 gets this but especially Kaku, Lucci and Kalifa. They're all assassins and rather unapologetic about the fact (Lucci even said that the main perk of their job is legally-sanctioned killing), including attempting to kill both Iceberg and Paulie immediately after their reveal. Lucci and Kaku are even revealed to have gone back to the government and joined CP0 during or after the time-skip. When Saint Charlos tries to enslave Shirahoshi, Lucci and Kaku are among those who stop Shirahoshi's family and new friends from intervening. But there's plenty of people who would love to see at least one of them join the crew or become allies.
Caesar Clown, despite being an unrepentant Mad Scientist specializing in WMDs, has gotten plenty of readers sympathetic toward his plight since his capture at the end of the Punk Hazard arc to actually want him to join the crew. (No doubt his comedy bits help him out a lot) It got to the point where Oda had to remind readers of his actions in Punk Hazard when a fan in the SBS wondered why Nami insulted and wished death upon him at every opportunity.
The Dressrosa arc, already suffering from Arc Fatigue, fell into this as the final blow was stalled off for several chapters, since Luffy's Gear Fourth had worn out and he needed time to recover his Haki, putting focus on random citizens running and the protagonists trying to slow down the Birdcage.
Whole Cake Island. The Straw Hats had already accomplished all their goals of obtaining Big Mom's Poneglyph, retrieving Sanji, and saving Sanji's family from an assassination attempt, and the story had already established that Luffy wasn't ready to take on Big Mom yet. But there are still about three volumes of contents as the Straw Hats on the Thousand Sunny struggle to face obstacle after obstacle in their way while Luffy fights Katakuri, and Sanji bakes a cake for Big Mom.
Evil Is Cool: Too many to list. It's easier to name the villains who aren't awesome, and many of them that aren't that impressive to begin with get better as the series continues.
Fair for Its Day: While nowadays Mr. 2 appears to be a bad caricature of the LGBTQ+ community and crossdressers, at the time of his debut an openly gay (and ultimately a positive one) character was something rarely seen before, especially in a series aimed at young teens, to the point some western releases and/or dubs remove the any reference to the "gay way".
Fan Wank: Oda often offers cryptic explanations on things (with intentions of fully explaining them months or possibly years down the line sometimes) or doesn't bother to explain things at all, leading to quite a bit of this among the fandom. Common topics include explanations for Pell surviving a nuke, Blackbeard's two Devil Fruits, or how exactly some of the abilities work (E.g. How Zoro can create illusions, how Luffy can spontaneously use fire or electricity, etc.).
Fetish Retardant: The overly hourglass-shaped proportions of female characters (especially post-Time Skip) comes off as too unnatural to be sexy to some people. The anime tends to exaggerate their proportions further (particularly with much larger breasts) as well as upping the Male Gaze, further pronouncing this trope.
Fight Scene Failure: Ever since Toei became adamant toward not going any farther than adapting one chapter per episode, the action-scenes, for the most part, have been showing an obvious drop in quality in an attempt to pad each episode out. Fights are painfully extended through the use of opposing stares and reaction shots, as well as the action itself coming off extremely slow-paced. Laziness will also crop up from time-to-time when all Toei will animate is a single still-frame, or even repeat the same scenes, most notable in the battle between Zoro vs. Pica when the anime took an entire episode for Pica to lumber all the way over to the King's Plateau and the exact same stomping motion of his foot was used at least three times. Worse, some adaptations will stagger at half-chapter pacing, causing certain scenes to be dragged out so badly that if Toei doesn't add new scenes to fluff things up a bit, the story will completely stall out.
Surprising absolutely no one, we have Doflamingo, who jokes about how Crocodile siding with the pirates instead of the World Government is "making me jealous".
Nami's fight with Kalifa. At one point, Nami admires how smooth Kalifa's skin must be and how she would want her to be her own Sexy Secretary. Lampshaded when she reminds herself that she isn't a Dirty Old Man.
Shiki and Roger. Shiki initially wanted Roger to join him (Roger fought back because it meant subordination), went on a rampage in Marineford to prevent Roger's execution, and the driving force behind his actions in the present is disappointment in how the seas without Roger have become.
Zoro and Tashigi. They seem impressed (to varying degrees) by each other's knowledge and commitment to swordsmanship when the first meet. Tashigi's resemblance to Kuina, Zoro's unwillingness to kill her, her mistaking this for chauvinism, and her subsequent The Only One Allowed to Defeat You attitude give their relationship some romantic subtext.
Trafalgar Law and Doflamingo, although it's mostly one-sided from Doffy's part. Law wants him dead, while Doffy wants him to be one of his subordinates... and he even chained Law to the heart seat of his castle. The fact that he saw Corazon (Law's idol and father-figure)'s name on Law's shirt and spitefully shoots Law's back for it is often interpreted as jealousy.
Foe Yay Shipping: Eustass Kid and Trafalgar Law have quickly become one of the most popular pairings of the Supernovas due in part to their position as reluctant and snarky Enemy Mines.
Some of the longer arcs have run into pacing problems, especially when it comes to flashbacks. For example, Skypiea had a flashback several chapters long in the middle of the climax, with plot-critical details(Noland's expedition to Jaya, how the Shandorans got blasted up to Skypiea, and the truth behind Noland's failed second expedition and execution). When Dressrosa had a longer and more drawn-out climax, including Law's flashbacks during the climax, readers started complaining.
Somewhat related to the pacing, while people have started complaining about padding in the anime adaptation since just before the Time Skip, the anime has always expanded on the manga in various ways, from adding new scenes and lines of dialogue to reaction shots and shots of characters walking. The difference is that in the past, the anime covered more than one chapter per episode, and used filler episodes to allow the manga to get farther ahead. Around the time the series got up to Sabaody Archipelago, leading to long arcs with no opportunity for filler arcs, the anime had to fall back on making anime episodes cover manga chapters, thus leading to the padding problem getting that much worse. This became an especially noticeable problem as of Dressrosa, which was already one of the longer arcs in the manga, and its pacing is slowed down to a drag by the anime adaptation.
For much of the series, some of the more epic battles happened almost entirely offscreen. In the early series, people didn't mind, since those glimpses of the most powerful fighters generally served to build up excitement for future battles (for example, Shanks and Whitebeard clashing aboard Whitebeard's ship post-Enies Lobby, or Ace vs. Blackbeard ending on a cliffhanger). However, as the series goes on, some people are starting to see this trope as a bit of a cop-out, such as when Kanjuro Kurozumi, the traitor in the Red Scabbards (a significant antagonist) is defeated and thought to have been killed offscreen, or when Jack, one of Kaido's Lead Performers apparently loses to Dogstorm and Cat Viper in their Sulong forms offscreen.
The series has long been reluctant to kill off characters outside of flashbacks. At the end of the Baratie arc, the fatally poisoned Gin's fate was left ambiguous, and while Igaram's survival seems farfetched, the fact that Robin pretended to kill him retroactively makes sense as her first act of betrayal against Crocodile. It only became a problem when characters' surviving is rather improbable (Pell surviving the detonation of a city-destroying bomb, Pagaya avoiding Eneru's lightning) and/or ruins the emotional impact of supposed character deaths (Bon Clay performing a Heroic Sacrificetwice and surviving). The series managed to buck the trend by killing off Ace and Whitebeard at Marineford, but later developments, like Sabo surviving his supposed death in Luffy's flashback, and Pound coming back in a cover story prove that this trend hasn't quite gone away.
There is pretty strong overlap between fandoms for One Piece and JoJo's Bizarre Adventure, primarily on the basis that they both have very distinct art styles, that Eiichiro Oda and Hirohiko Araki are extremely pop culture savvy in regards to both Japanese and western media and flaunt it in their work whenever they can, and that both series are Long-Runners whose stories have only gotten wilder and wilder since they began.
One Piece fans and Pirates of the Caribbean fans can get along quite well thanks to similar pirate theme between the two and Jack Sparrow, who is more or less an adult, Devil Fruit-less version of Luffy.
In the Volume 15 SBS, Oda explains sailing ceremonies, where a bottle of liquor is broken against the bow of a new ship to celebrate its completion. If the bottle doesn't break, the ship is cursed with bad luck. Right after that, Oda drew a short scene where Kaya is performing the ceremony for the Going Merry. The bottle doesn't break.
In the Post-Enies Lobby arc, Zeff and co. of Baratie say that they will hang up the badly-drawn poster of Sanji and say that he lived and worked there. Much later on, Judge blackmails Sanji with a picture of Zeff, and reveals he knows all about the Baratie. The chefs' flaunting may have been what caused Big Mom's intel network to link Zeff and Sanji.
In the Sabaody Archipelago Arc, Duval wears an iron mask to hide his face because it looks exactly like the drawing used for Sanji's wanted poster. Turns out, Sanji was forced to wear an iron mask during his childhood because his father didn't want to see his face (both figuratively and literally).
In the Punk Hazard arc, when Momonosuke first encounters Luffy, he says that Luffy can't be a pirate because pirates are giant men, weighing 400 kg, and are more fierce looking. The man who best fits that description is Kaido, who we later find out, killed both of Momonosuke's parents.
In the Thriller Bark arc, Lola kept asking men (particularly strong men) to marry them, and the caption revealed that she did this over 4,000 times. The Whole Cake Island arc reveals that by running away from an arranged marriage her mother Big Mom set up, she screwed up a very important political union that could have given her enough power to defeat her rivals and become Pirate King. In any case, Big Mom is still very sore about this, and Lola could be trying to make it up to her with her casual marriage proposals, unaware that her mother has disowned her and plans to kill her for her disobedience.
The Straw Hats find out in the Dressrosa Arc that women in Dressrosa are notoriously "passionate" and it's a common occurrence for them to stab men who cross them or just stab them in betrayal. Zoro comments that a Chivalrous Pervert type like Sanji will "get stabbed for sure" to which Sanji remarks that he wouldn't mind. It's funny at the time, but two arcs later Zoro's words echo when Sanji's chivalrous nature and soft spot for women ends up getting him metaphorically stabbed in the back by a very sadistic Bitch in Sheep's Clothing.
In the Enies Lobby arc, Kalifa would say "that's sexual harassment" when her superior, Spandam, did or said almost anything. Following the Harvey Weinstein incident in 2017 along with victims of sexual harassment coming forward with the #MeToo movement, this quirk is suddenly no longer funny.
Gateway Series: Regardless on how bad the bowdlerizing is, at least the 4Kids dub had made some viewers to become a fan of the manga before or after they found out the source material.
Genius Bonus: There are dozens of characters Named After Someone Famous, mostly pirates, but most are only famous if you're a historian and/or a fan of real-life pirates of the past. Many readers may recognize Edward "Blackbeard" Teach and the One Piece characters named after him (Edward Newgate and Marshall Teach), or Anne Bonney and her One Piece counterpart Jewelry Bonney. There are way fewer readers who will know Roronoa Zoro is named after François l'Ollonais, Cavendish is named after Henry Cavendish, or Scratchmen Apoo is named after Chui A-poo. Trafalgar Law gets a reference in both parts of his name: He's named after English pirate Edward Low and the Trafalgar-class submarine.
Germans Love David Hasselhoff: Carrot, big time. While Japan likes her enough, the rest of the world adores her. So much so that her popularity managed to propel her to 8th place in the first Worldwide Popularity Poll. Beating out titans like Ace and Sabo. Regional breakdown showed her getting 24th place in Japan, but anywhere from 4th to 8th place in the rest of the world.
Many fans note that One Piece really starts coming into its own during the Arlong Arc (the first arc where Luffy and company profoundly stuck their noses out for someone who had been badly hurt and oppressed), and even after a few hundred chapters, simply hasn't stopped delivering in entertainment.
Alabasta is another moment for the series, being the highly anticipated payoff to the Baroque Works Saga, featuring a villain who soundly defeats Luffy twice and introducing some of the mysteries of the world, such as the Poneglyphs.
As for the anime, it really came to be its own series with the greater animation budget, fighting scenes and overall story with the beginning of the Water 7 Arc.
At the end of the Syrup Village arc, Luffy invites Usopp to join his crew, despite the fact that Usopp isn't particularly strong(unlike Zoro) and doesn't fill any necessary roles(unlike Nami and most of the other Straw Hats) simply saying they're friends. At the time, it seems like a nice thing to do for his new friend, but in the Water 7 arc, Usopp seems to believe Luffy brought him along out of pity despite the fact that Usopp's ambitions are nowhere near as lofty as Luffy's.
In the Jaya arc, Sanji, and later on, Zoro both bring up the possibility of getting a new ship to replace the damaged Going Merry, which Usopp yells at them for. Anybody who knows what happens to the Merry later on will find that brief moment to have a much stronger impact. This is compounded when Luffy reassures Usopp by calling Merry an irreplaceable member of the crew after Zoro suggests it. Makes the future event of Usopp leaving the crew, and dueling Luffy even more heartbreaking. Even worse, the snapped keel (the main reason why the Going Merry can't be repaired) was collateral damage from Bellamy beating up the Saruyama Alliance during that arc.
Zoro mocking Sanji's Ball on his head as a crown of "Moronica" from the Long Ring Long Land arc has became harsher after the reveal of Sanji's past as a Vinsmoke family in the Germa Kingdom.
In the localization of the manga, after Lucci tells Sanji, "From the way you open doors, you don't seem to be a very patient fellow," Sanji snarkily says, "You're right. My parents raised me wrong." His father was a horrible person who wanted Sanji to be a sociopathic Super Soldier, so not only did Sanji's father not raise him well, but Sanji didn't turn out the way Judge had hoped.
One could almost be thankful that Yasopp chose to distance himself from his son Usopp's life given what happened with his English voice actor.
Lola giving Nami part of her mother's Vivre card seems like a nice gesture, until it turns out that Lola's mother, Big Mom, one of the Four Emperors wants to kill her, unbeknownst to Lola. Granted, the Vivre card turns out to be a useful tool for the Straw Hats, but in hindsight, Lola comes off as rather thoughtless.
The Marineford scenes where Blackbeard gains Whitebeard's quake powers and unleashes them on Marineford, causing Tsunamis to head towards Sabaody was aired shortly before the 9.0 Quake and Tsunami disaster in Japan.
One of Brook's most awesome moments comes from him staring down Big Mom and dismissing her threats with the line "What kind of fool would have come planning to die?" Later that arc, it turns out Pedro did come planning to die, since he got most of his lifespan stolen the last time he encountered Big Mom and is determined to make his death count.
Fisher Tiger and Koala. Even after the ambush from returning Koala to her village by the Marines, he declared on his deathbed that she, not knowing of the hatred between humans and Fish-men, represents the hope for a better future. Skip to fifteen years, and find out that Koala has joined the Revolutionaries, and when she's not starting uprisings against oppressive governments, she teaches Fish-man Karate. She's also a good friend of Hack, a Fish-man who's an acquaintance of Jimbei's.
After Sanji's tragic past that was revealed in Whole Cake Island, any scene between him and Zeff could qualify for this, especially in the wake of Koji Yada (Zeff's Japanese voice actor)'s death.
At the end of Luffy's flashback almost no one believed Oda would suddenly introduce Sabo, another "brother" of Luffy and Ace only to suddenly kill him off. Then Sabo appears during the Dressrosa arc, revealing he's been working with the revolutionaries and simply lost his memory.
In Chapter 986, Kurozumi Kanjuro, the traitor among the Red Scabbards, is shown lying in a pool of his own blood, surrounded by the comrades he betrayed, and a flashback scene shows them in happier times. Many fans don't believe that he's actually dead, since they find it hard to accept that the traitor would be Killed Offscreen in such an anticlimactic fashion. Sure enough, Kanjuro entered the fray once more in Chapter 1007.
Hype Backlash: Because of the high critical reception and how often fans consider the series "the best manga ever made", it's only natural that many people disagree with the notion and think the series, while usually considered good, doesn't deserve all the hype.
It's Popular, Now It Sucks!: One Piece is the best selling manga in history and the second best selling comic book of all time. It's also been consistently popular all over the world for almost two decades. Naturally, some people are taken aback by this popularity and consider the series overrated.
In general, most One Piece arcs tend to follow the same formula and, while some argue that each arc manages to have its own identity and different feel, other fans have gotten sick of the formula and the series has gotten too repetitive, it doesn't help that its length means there have been many arcs and therefore it's very easy to find the plot-formula.
One of the most commonly cited examples is Dressrosa, compared to Alabasta. In both arcs, the Straw Hats seek to defeat one of the Seven Warlords of the Sea, who is trying to/has taken over a country, and they gain help of that country's princess and an honorable Marine. Some members of Doflamingo's crew (Gladius and Machvise) even have similar powers to members of Baroque Works (Mr. 5 and Miss Valentine).
The Going Merry gets replaced by the Thousand Sunny. Since the Straw Hats' ship is often shown in promotional material, it's hard to hide the Straw Hats getting a much larger ship that looks rather different from the old one.
The identities of the 9 Straw Hat crewmates before the two year Time Skip. Again, the main cast is prominently featured in promotional materials, even members like Robin or Franky, whose joining comes as a bit of a surprise.
Nami, the self-centered, mood swinging, thieving Insufferable Genius of the Straw Hat Pirates, comes off this way in the East Blue Saga. She's rather hostile to Luffy and Zoro, views her association with them as an alliance of convenince, and eventually steals their ship. However, her personality, in particular, her obsession with money, is explained as a result of being an orphan raised by the Marine officer Bellemere, along with another girl Nojiko. The family was too poor to afford the things Nami wanted, and when Arlong came along and imposed a tax on the people in her village, with the penalty for not paying as death, Bellemere only had enough money to either pay for herself and hope they don't find out about Nami & Nojiko or pay for the two of them; she chose to save her children rather than herself, and was shot in front of her children's eyes. Arlong then forced Nami to be a part of his crew, even going so far as to forcibly tattoo her, and said that if she manages to get 100 million belli, her village will be freed as well as herself. Even worse is that Arlong had no intention of keeping his end of the bargain, and wanted to enslave her for the rest of her life. Good thing she met Luffy and the other Ragtag Bunch of Misfits who dealt with Arlong personally. She ends up becoming nicer after the end of the Arlong arc.
Kuina, Zoro's childhood friend/rival, came off as rather arrogant and insulted Zoro a lot but she was covering up her huge self-esteem issues about her gender and being a swordswoman, being told that despite her talent, she will not be able to pursue being the best swordswoman in the world, or inherit her family dojo. Her father's suggestion in the anime that she might just have overcome her own limitations if she hadn't died makes her sudden and pointless death in an accident that much more tragic.
Montblanc Cricket had to deal with the shame of his heritage because of the legacy left behind by Norland. His own (original) crew abandoned him when he decided to resolve his issues with the shame placed upon his ancestor. He initially was annoyed with the Masira and Shoujou for being fans of the tale. But came to love them and admitted he was glad they came along as the loneliness after being abandoned by his original crew was unbearable.
Boa Hancock was introduced as a puppy-kickingVain Sorceress. She showed herself to be an aloof, arrogant, complete Jerkass who wasn't above defenestrating her grandmother for giving the sincerest of warnings and petrifying her subjects for allowing a man (Monkey D. Luffy) onto their island. She was even complacent with her two younger sisters, Marigold and Sandersonia, breaking them in their petrified state just to mess with Luffy — just a hair's breath of crossing the Moral Event Horizon. However, when Luffy defeated the sisters and spared their pride by hiding their tattoos, this brought to light another side of Hancock unseen before: as she explained to Luffy, the tattoo was forced upon Hancock and her sisters (sensing a pattern here...), and is an eternal source of shame from slavery under the World Nobles, descendants of the founders of the World Government and, as shown in the previous arc, a whole 'nother ball of the MEH wax, known for kicking, shooting, and blowing up their slaves if they get frustrated or bored with them. The three sisters, who were just pre-teenage girls back then, spent four whole years enslaved to those bastards and were force-fed a Devil Fruit strictly for their entertainment. Hancock's own experience was such that she couldn't even talk about it without being reduced to tears. The very fact that she kept the law of her island to the letter could be explained due to her personal experience with one particular World Noble who was in her words "the very object of terror itself", which jaded her view on the opposite gender. It's only that Luffy didn't care that she and the other two were slaves, and hates the World Nobles anyway (for shooting a friend of his, who wasn't even one of their slaves) that caused her icy persona to warm up a bit, and even fall in love with the guy.
The Whole Cake Island arc shows that Charlotte Pudding is one. She spent years being abused by her family for her Third Eye, Big Mom included, until she snapped and became the sadistic actress we see in the present. Even after she earned her keep, Big Mom still antagonizes her about not unlocking her eye's potential, and her role as the family's Honey Trap doesn't seem to help her sanity much, either. When Sanji says her eye is beautiful, she breaks down on the altar and has her first real case of Inelegant Blubbering in the story.
Even Gecko Moria is this. Losing all your crew to someone like Kaido would fuck anybody up; hes lucky to even be alive! Yes, he does attempt his take on a Zombie Apocalypse, but given his desire for a crew thatll never die, you almost feel bad for the guy; especially since he barely made it out of Marineford alive.
Eustass Kid is a Jerkass to the nth degree, and his first mate Killer isn't exactly all that nice either, but it's hard not to have at least some sympathy for everything that happened to them since the end of Dressrosa. It turns out that one of their allies, Apoo, completely screwed over them and their other ally, Hawkins, as he was working for Kaido all along and him joining the alliance was a trick from the start. Hawkins, despite not being in on this deception, chose to save himself and bend the knee to Kaido, and did nothing at all to help Kid and Killer when they fought Kaido, lost, and were beaten up and imprisoned. Kid later finds out that, while he was in jail, Killer (his best friend since childhood) was forced to eat a faulty SMILE Fruit that made him laugh all the time (even though Killer deeply hated his laugh) and work for Orochi, and Hawkins speculates that the rest of Kid's crew was forced to work for the shogun as well. Apoo's and Hawkins's respective betrayals, and what happened to Killer in the aftermath, seems to have deeply jaded Kid, who states that the only people he'll trust from now on are his own crewmates.
While the series rarely touches upon the subject of romance, it has its share of shipping, especially between the crew of True Companions. In particular, Nami is often believed to be Ambiguously Bi given her interactions with many female characters.
The Wano Arc has been incredibly well received by gay and trans people in the West due to the characters O-Kiku and Yamato who are a trans woman and (potentially) a trans man, neither of whom are being used for comic relief.
Macekre: The 4Kids dub gets a lot of flak for skipping entire arcs, unnecessary character name changes (Smoker gets Bowdlerized, which makes sense, but Ace is a problem?), generally weird edits, and a host of other problems that are associated with the company. Though to be entirely fair, 4Kids themselves wanted nothing to do with the show, as they were well aware of how un-family friendly it was, but they were forced into dubbing the show by Toei themselves, as they wanted to get it into foreign markets as soon as possible and would only license other shows to 4Kids as part of a packaged deal, so they were basically forced into dubbing One Piece against their will, hence why they dropped it after a year.
Dracule "Hawk Eyes" Mihawk is the World's Greatest Swordsman, a laidback yet lethal Warlord of the Sea who serves as Roronoa Zoro's greatest challenge. His sword skills practically unmatched and capable of decimating any opponent he faces, Mihawk introduces himself to the Straw Hats having annihilated Don Krieg's entire fleet singlehandedly before easily beating Zoro and regarding Luffy's attempts to attack him as mere annoyance. Later taking part in the Marineford conflict, Mihawk casually destroys waves of enemies with ease and puts Luffy on the run, with Mihawk barely breaking a sweat even as he swiftly defeats Buggy and faces Crocodile in combat. Mihawk personally trains Zoro over the course of two years out of respect for the man's tenacity, and Mihawk takes the news that he's been declared wanted by the government with a mere chuckle and an invitation to an army of terrified Marines to face him in combat.
Crocodile, one of the "Seven Warlords of the Sea", is the brilliant master of the Baroque Works syndicate. Playing himself off as a public hero while running the aforementioned criminal organization, Crocodile manufactures a drought and a rebellion to weaken the Nefertari family in Alabasta, while plotting a takeover himself. Showing contingency after contingency, Crocodile manipulates countless people, including his right-hand woman, Nico Robin, with whom he intends to seize the superweapon Pluton in order to cow the World Government into recognizing his authority. Even after defeat, Crocodile later returns in Impel Down and helps organize the jailbreak with his enemy Monkey D. Luffy.
Rob Lucci is the strongest member of Cipher Pol's CP9 division. A brilliant fighter who infiltrated a hostage situation and killed every hostage to remove the pirates' leverage before killing the pirates themselves as a teenager, Lucci later goes undercover in Water 7 with his disguised team to recover the Blueprints of Pluton. Fooling all there by faking their deaths, Lucci later delivers a brutal beating to Luffy and escapes with Nico Robin in tow, later giving Luffy one of the most brutal and difficult fights he has had to that point.
Sengoku the Buddha is the most brilliant of the Marine Admirals. The top Fleet Admiral of Marineford, Sengoku leads the execution of Portgas D. Ace, revealing to the world that Ace is the son of Gol D. Roger, the former Pirate King. With the arrival of Ace's captain, "Whitebeard" Edward Newgate, Sengoku reveals a major trap for Whitebeard, sapping the morale of his forces with a carefully planned lie, trapping the pirates and closing in Marine forces, turning a near loss into a total rout for the strongest man alive with his own cunning.
Charlotte Katakuri is the second son and strongest soldier of Charlotte "Big Mom" Linlin, one of the Four Emperors of Grand Line. A keen, analytical fighter, Katakuri is the strongest of his mother's Sweet Commanders who dedicates himself to protecting his family and ruthlessly dispatching threats. Going with the plan to catch and slaughter the Vinsmoke family, Katakuri proves a deadly threat to the Straw Hats, planning an ambush with his family before engaging Luffy himself. When his true nature and unsightly features are revealed, it is shown Katakuri adopted his stoic persona as a way to protect his siblings before he embraces Luffy as a truly worthy enemy, even wounding himself after one sister's treachery so their fight will be an even one.
Buggy, both in-universe and out. He's a goofball who was defeated early on, but his history as a former cabin boy on the Pirate King Gol D. Roger's crew, as well as several coincidences during the Marineford War, leads to many lauding him as one of the most powerful pirates of all time.
Many characters who are silly and weak such as Gaimon, Foxy, or Tonjit are hyped up as secretly as strong as the Four Emperors or the Admirals.
Ace, after his not-so-glorious death that leads many to compare him to a donut, as well as the fact he doesn't win any on-screen fight except against mooks.
Also Kid, due to most of his panel time post-Timeskip involving him being beaten up, betrayed or screwed over in some way. Doesn't help that he's prone to engage in Trash Talk that he can't always back up.
Bellamy the Hyena is best known as "that guy Luffy beat with one punch". Though this died down quite a bit after he came back in the Dressrosa Arc and Took a Level in Badass.
Marines are often played as evil by the fandom; the Marines are run by corrupt Jerkasses and Smug Supers, while the pirates are romanticized as freedom-loving people who want to live life to the fullest outside the law. For the most part, the Marines are portrayed as morally questionable, and several good pirate crews are seen (such as the Straw Hats). However, it is made clear that crews like the Straw Hats are exceptions. Several pirates are evil, cruel, and murderous, many of them infinitely worse than the Marines. For the most part, the Marines are at least trying to do the right thing, and want to protect people from pirates and other criminals. The dynamic between pirates and Marines is more a case of Grey-and-Grey Morality, while fans tend to simplify it to pure Black and White.
Several fans believe that Sanji's inability to hit woman is a trait that makes him weak and that calling for Robin's help after being captured by Black Maria is a sign of cowardice. However, Black Maria herself voices this belief while Robin promptly shuts her up and replies to like that Sanji trusted her, while it's later shown that Sanji's refusal to hit a woman is one of the traits that makes him human in contrast to his cold and emotionless siblings.
Those who don't like the Hotter and Sexier post-Time Skipfemale design often criticize Oda. While Oda is a self-admitted pervert and women have gotten curvier over the course of the story, he actually still does draw his women's breasts to be much smaller and at a more consistent size than Toei, who are the ones really responsible for ballooning up bust sizes.
As it has been pointed out multiple times by multiple people in the industry that Toei approved every single alteration 4Kids made to One Piece. Changing a gun into a spring-controlled mallet... thing? Somebody at Toei approved that. Digitally altering Laboon into an easily-destroyed iceberg to completely skip a rather important dozen-plus episodes of plot simply to get to the "cute" character more quickly (and causing severeplot holes had the show run for much longer)? Yep, somebody at Toei signed off on that too. The "One Piece Rap"? A Toei exec... well you get the idea.
Never Live It Down: One Piece, and to a lesser extent, Oda, will always be known for ruining a perfectly established sacrifice by allowing Pell to somehow survive a nuclear blast despite last being seen carrying the bomb to a safe distance, and having it explode in the sky along with him. It's because of this particular incident that Nobody Can Die became relatively well-known throughout the series, and is described to be the worst Ass Pull that Oda ever wrote throughout the entire manga.
No Problem with Licensed Games: While most One Piece games haven't seen a release overseas, they're genuinely fun to play regardless, ranging from role-playing games, mini-game mashups, and even a dungeon crawler with Tony Tony Chopper as the main character is on the Wonderswan Color. Additionally, Unlimited Adventure was a pretty good Survival RPG/Beat 'em Up, with its own unique level up and item creation systems. And Unlimited Cruise (1 and 2) isn't just a good licensed game, it's a good game overall, with ratings ranging from 7 to 10.
Since Toei Animation has pretty much abandoned all usage of long Filler Arcs ever since the Straw Hats separated, which previously allowed for the manga content to space itself out from the anime, this trope is Toei's current day answer to make sure that their anime adaptation never overtakes the manga. As a result, a single anime episode will go to great lengths to extend the content as much as possible to fit in one manga chapter's worth of content. Sometimes even less, which has resulted in the later Story Arcs of the series having more episodes than there are chapters. While this Padding technique can be looked at as completely justified, it can be grating as well since it causes the pace of the story to drop drastically. Even though Toei still adds filler arcs, they tend to be short-lived and not too ambitious unless a really good idea comes up or Oda gets on board with production or they tie in to a movie.
One of the most notorious cases is the flashback of Rebecca and the Soldier, which plays roughly 48 times during the anime adaptation of the Dressrosa arc.
For the Whole Cake Island Arc, Luffy, Nami, Chopper, and Carrot getting lost in an enchanted forest was used as a means to simply keep them preoccupied while Oda used that time to develop Sanji's current problem regarding his Vinsmoke family joining up with Big Mom. It's especially bad in the anime, which adds scenes from Luffy's ten-hour battle with Cracker to pad things out in the middle of episodes focusing on Sanji and the Vinsmokes. One video estimated that one sample episode from Luffy's fight with Katakuri was 43% extraneous material.
Periphery Demographic: In Japan, One Piece is most often read by people who don't normally read manga. For very obvious reasons, it is especially popular with middle-aged housewives. Thanks to its extremely long run and its handling of more mature themes, a good part of its readers are grown up adults in spite of it being a manga published in a magazine aimed at teens, and in Japan whole families read One Piece together, since people who started reading One Piece as kids might now have families of their own. It has also gathered the interest of many history buffs thanks to the often obscure references to many historical events, figures or famous legends, particularly around piracy.
Hody Jones, who many view as a poor rehash of Arlong. His misanthropy by his admission, has no personal basis; he simply grew up in an environment filled with like-minded Fish-men. His performance in battle was also miserable, losing in a Single-Stroke Battle to Zoro while underwater, and his drugged-up form was little more than a punching bag to Luffy.
Momonosuke has a role similar to Vivi, Shirahoshi and Rebecca as royalty who needs the Straw Hats help to save his home. Yet hes far less popular than any of the three, for reasons ranging from Dirty Kid antics to being a mostly helpless child given a lot of importance, although his moment of courage when he's about to be executed saved him in the eyes of some fans. He ranked at an abysmal 180th place in the global poll, despite being with the crew since Punk Hazard and the poll taking place in the middle of the Wano arc where he's most important.
Self-Fanservice: Despite Yamato's figure being very similar to most female characters in the series (thin with large breasts), it is very common for fanart, especially from the western side of the fanbase to draw him much more muscular and masculine looking that he is on the manga.
Namis emotional cry for help to Luffy back at Cocoyashi Villages crisis against Arlong and his crew is, undoubtedly, one of the most memorable moments in the entire series; that event, however, is the singular point where many of those who like to ship Luffy with Nami will trace themselves back to, the moment in which Luffy gives his straw hat to Nami is a key event with a clear underlying message: Luffy trusts Nami with his treasure, reassuring her that he did not see Nami as a traitor, she immediately understands what Luffy means by quickly remembering how Luffy didnt like random ruffians touching his prized hat; later during the climax of Skypea, Luffy also gives his straw hat to Nami, as she was panicking thinking about how Eneru could even be dealt with, Luffy does it as a mean to calm Nami down and trust he will win as it is only natural to the future King of Pirates; shippers, on the other hand, likes to see those events as something more than just trust, which was further fueled by early anime filler really pushing the idea of Luffy preferring to leave his hat with Nami whenever a situation called for it.
Robin and Franky has always been one of the more popular ships due to people viewing them as the two parents who watch over the rest of the Straw Hats. They were, after all, the oldest of the crew before the arrival of later crew members. The shipping really picked up steam during the Punk Hazard arc when it's shown that Robin is perfectly comfortable with acting as a Lap Pillow for a sleeping Franky.
Ever since his introduction arc, it's quite common to see people pair off Usopp with Kaya; the rich Ill Girl that Usopp often visited in his village to tell her outlandish stories in an effort to cheer her up, and then protected her from her butler who turned out to be a dangerous pirate. As a result, Kaya tends to be portrayed as the wife that's waiting for her husband to return home from his grand adventure.
Shocking Moments: Tends to rise the farther along the Grand Line the Straw Hats sail, with a very sharp increase ever since Amazon Lily, and especially since the start of the Marineford arc. Post-timeskip? Off the charts.
The Marineford Arc in its entirety. Also know as "The Paramount War", the "War of the Best", and "The Holy Shit! Arc".
Dressrosa Arc becomes even bigger than the Marineford arc for this. Loads of fighters, thus loads of fight scenes, and no less than 3 Dark and Troubled Past (prominently Law's, in which it's revealed that he's a D) are shown here.
The Zou Arc marks the first time pirate bounties break into the billions. Not only that, but the highest revealed bounty to date was only about half as high- Ace's 550 million berries, who himself was one of the most infamous names of any pirate alive at the time simple due to his lineage. There is also the fact that this arc introduces a new kind of Poneglyph that is mission-critical to finding Raftel, and reveals that two are in the hands of an Emperor apiece, meaning that if the Straw Hats want to make it to One Piece, they MUST confront these Emperors and their forces on their home turf, and almost certainly will have to engage in fights against the Emperors themselves.
Whole Cake Island Arc, seeing the very first time the Straw Hats are in a serious head-to-head confrontation against a Emperor, featuring much more explicit and repeated instances of death, and showcasing a villain with the power to instantly murder people, a gigantic family of equally capable pirates, three of which are on Jack's level, if not higher, a villainous organization of mercenaries threatening to conquer the North Blue that is being deceived, and at least three groups of people plotting to take down a common enemy. On top of all this, the unspoken bits of Sanji's past come into light and actually dwarf the Dark and Troubled Past he was first seen suffering in the Baratie Arc- in fact, they're a lead-in to this suffering that makes his ordeal of being marooned look like a gleeful walk in the park!
Signature Scene: One Piece is a very long series, therefore it has a lots of iconic scenes. The more notable ones being:
Gold Roger's execution, especially since his last words are what instigate the plot.
Shanks losing an arm, and passing down his straw hat to Luffy is easily a cover shot for the series.
Nami's breakdown leading her to finally ask Luffy for help, to defeat Arlong and the subsequent Power Walk to Arlong Park, the latter moreso in the animated adaptation.
The crew departing from Alabasta, holding their arms up with the X mark towards Vivi.
Robin's declaring to the rest of the crew she wants to live, at Enies Lobby, after Luffy declares war on the rest of the world for her sake.
Going Merry's funeral, the crew watching the ship burn as to remember their adventures with her.
Zoro standing tall, his body completely destroyed after fighting Ryuma, Oars with Moria, Kuma, and then taking all of Luffy's damage taken from all his previous battles, simply claiming afterward that "nothing happened".
Ace tearfully dying in Luffy's arms at Marineford.
Take That, Scrappy!: After the Time Skip, one of the more notable casualties of Blackbeard's hunt for Devil Fruit users is Absalom, who, among other things people hated about his character, failed to use his Devil Fruit to the fullest extent.
Tear Dryer: At the climax of the Skypiea arc, Enel throws out his strongest attack, "Raigou", a gigantic sphere of lightning that he'll use to decimate the whole Skypiea. We then get multiple shots of different Skypieans in despair who are saying their prayers. Then Luffy shows up and uses a special technique (aided by the golden ball that's grafted to his right arm [long story] and his Rubber Man powers) to disperse the lightning sphere; this brings back joy to the watching Skypieans and the other heroes.
There was a lot of outcry after Toei forced 4Kids to edit the series as part of a licensing package deal in 2002; even 4Kids wasn't happy with the result. When Funimation acquired the license to the series in 2007, a different section of the fanbase criticized the Funimation voices for not matching the ones 4Kids used.
While Robin had a tanned or dark complexion for the pre-timeskip anime, her complexion became paler after the Time Skip. While this does match the manga, in which she's always had a pale complexion in the colored pages, the change angered fans who'd liked Robin's pre-timeskip design.
Some readers who'd grown attached to Franky's pre-timeskip design, which is one of the most colorful and memorable Straw Hat designs, weren't thrilled with his post-timeskip appearance, particularly the buzz cut he had in the first few post-timeskip arcs.
Depending on who you ask, you'll get this complaint about any character that the fans wish had become a member of the Straw Hats to follow along on the journey. The list could go on for awhile due to One Piece's Loads and Loads of Characters. Perhaps the earliest example of this was Vivi where some people wish that she went through with ditching Alabasta for the Straw Hats once it was time to sail to the next island. Other examples include the Skypieans, such as Conis or Wyper, since despite the potential of possibly having a unique Skypiean character join the crew, such a case ended up not happening.
When it comes to the Straw Hats being given the spotlight for important fights, some people tend to complain that Robin has gotten the worst treatment since any time she shows off her abilities are usually when she's in the support role, and not as the main fighter. Her only standout duels are against Yama during the Skypiea arc, Hammond in Fish-Man Island, and later Black Maria in Wano, all of which are very short. Some people may argue that Robin has fallen behind the others, due to mainly being reliant on her Devil Fruit powers, while others argue that as a formerly powerful antagonist who gained some new moves over the course of the Time Skip, she should be a capable fighter.
Whenever there is a discussion about a Straw Hat who hasn't received much screentime recently, the one most frequently brought up is Chopper who, since Punk Hazard, hasn't received a moment which showcased his abilities and only served as device to heal the crewmembers or as a mascot.
There are instances of characters being introduced with hints of backstories, intriguing designs, and character quirks only to be completely dropped soon after. The most egregious example are the General Zombies of Thriller Bark, who literally had a bridge dropped on them. Well, bits of a bridge, anyway. The same goes for the many pirates introduced in the Marineford Arc. But there's plenty more where that came from.
While Jimbei is invited to join the crew at the end of Fish-Man Island, his actual joining has been delayed for so long, first because of him having to sever ties with Big Mom, and then because of staying behind to deal with her and allow the Thousand Sunny to leave. He finally joins them for good in the Wano arc, but many feels he, especially someone as important as a helmsman, should've joined as soon as Fish-Man Island.
When it comes to the 3 Sweet Commanders of Big Mom's pirate crew, a lot of people tend to poke fun at how useless Smoothie turned out to be for her Charlotte family during the Whole Cake Island arc. The other 2 commanders, Cracker and Katakuri, engage in full battles against Luffy, unlike Smoothie who simply follows the Thousand Sunny and attempts a couple of slashes in her giant form. This left many fans believing that Smoothie failed at living up to the hype as one of Big Mom's strongest crewmen.
Toki. She turns out to be a time traveler who was born during the Void Century, so some thought that she'd end up sharing important revelations about that time period. This never ends up happening, and the only use she has for her Time Time Fruit is to send Momonosuke, Kin'emon, Kanjuro and Raizo forward in time, an act that results in her death.
Punk Hazard has a neat setting where half the island is ice and the other half is fire due to the land being transformed from a past fight between the admirals, Kuzan and Sakazuki. However, a vast majority of the arc has the Straw Hats dealing with Caesar Clown and his minions at his base that's been set up within the island's ice half; meaning that barely any time is spent on the island's fire half.
In the Dressrosa arc, when Rebecca reaches Diamante, the man who killed her mother, instead of fighting him, she flees from Diamante and cries until Kyros saves her and hijacks her revenge arc (In fairness, Kyros had his reasons to fight Diamante as well), while Rebecca ends the Dressrosa arc without getting any meaningful fights.
The Barto Club parting ways with the Straw Hats at the start of the Zou arc was mainly a thinly-veiled excuse to get a group of superfluous characters away from the main plot, who by their own admission felt they were getting in the way of things, but one can't help but wonder what would have happened had they stuck around.
Despite the presence of bounties and their importance in the story, after the Baroque Works saga, there hasn't been any bounty hunter in the story and only the marines are shown hunting down pirates with bounties.
Tough Act to Follow: As the Water 7 arc is considered one of the high points of the series, and one moment at which the series started Growing the Beard, the Thriller Bark arc, which followed Water 7, is often unfavorably compared to it. It doesn't help that the arc after that is a significant Wham Episode.
While there has always been some controversy about Oda's portrayal of female characters (like their near homogenized designs compared to the wide variety of male characters and Oda's alleged protectiveness from serious injuries since his daughter's birth), complaints have reached a head during the Dressrosa arc.
Boa Hancock can fall under this, being an extremely self-centered misandrist and petty bitch who embodies Screw the Rules, I'm Beautiful! to such a degree that it's almost painful to watch. Her Freudian Excuse that she was enslaved by World Nobles doesn't make her misandry any less irrational, as there are plenty of female World Nobles and male slaves, and the later Fish-Man Island arc's narrative is quite adamant about not judging humanity as a whole based on the World Nobles.
While it's easy to feel sorry for Luffy as his brother Ace is killed by Akainu, many fans don't feel the same way for Ace himself because, not only did he go after Blackbeard against Whitebeard's orders because he couldn't stand that Blackbeard had disgraced their father by betraying the crew like that, but when he's finally freed after no small amount of bloodshed, over which he wangsted for the first half of the arc, he stops escaping because Akainu has insulted Whitebeard. Despite his allies, including Luffy of all people, pleading with him to ignore the jibes, he fights the Admiral and is killed by him. It can be difficult to feel terribly sorry for him when not only did he disregard the sacrifice of the dozens if not hundreds of his allies that died for his sake, he gets himself killed in a glaring case of Idiot Ball, rendering all their efforts pointless..
Momonosuke on paper is a poor orphan kid whose parents were killed horribly, his country was taken over, and has a massive amount of responsibility laid on his shoulders as heir to his clan. But Momonosuke is also a Dirty Kid who exploits his apparent innocence to grope Nami and Robin and acts like such a Bratty Half-Pint that most readers/viewers would rather throw him under a bus than respect and sympathize with him.
As per typical of most Shonen series, an uninitiated American might be surprised that such a bright, colorful show that's ostensibly "made for kids" (according to Oda himself) features swearing, alcohol use, heavy tobacco use, scantily clad women, and the occasional Family-Unfriendly Violence like bloody mid-combat amputations — all of which have increased over the series' run. The most dissonant value though would probably have to be the buxom, Stripperific, and Male Gaze prone Rebecca (among a few other teens like Vivi and Shirahoshi, who often had the 19/21-year-old Sanji hitting on them) who's only 16-years-old, which would be a major no-no on a kid's network in the West. So, it's no surprise that, aside from Funimation, this show has largely been Bowdlerised whenever it's green-lit for America.
It's not uncommon in One Piece to see a loving parental figure hit their child at least once or even actually beat them frequently, such as Garp, Zeff, or Bellmere. Disciplining through violence in Japan, however, is largely seen as perfectly acceptable as long as it's warranted and done to make the kid a better person. Out West, however, this depiction of parenting is far more likely to be scrutinized as child abuse regardless of the preceding circumstances.
Vindicated by History: Happens to most of the post-timeskip arcs. Since the majority of the fandom has been following the series weekly since the timeskip, it causes most of the arcs to appear weaker when read chapter by chapter than in their entirety like happened to the pre-timeskip arcs.
When it first came out, the fans' reaction to Fish-Man Island was very negative, because it was often considered the worst arc of the series, and it didn't help that Fish-Man Island had been built up since Enies Lobby. With time, its reception among the fandom has improved thanks to its nuanced story about racism and doing a good job at showing the skills the Straw Hats have learned during the time-skip.
The Dressrosa arc wasn't exactly well received at first because of its incredible length and its refusal to end but, once it ended, many fans noted that most of the pacing problems are absent if read or watched without having to wait a week for every chapter and it is now mostly regarded among the best story arcs of the entire series. This is moreso in the manga, as the anime is still considered painfully slow.
Thanks to Funimation's dub of the anime series, it really helped fans who loathed the original 4Kids dub to like them a lot more than the original dub.
Visual Effects of Awesome: Any scene animated by Naotoshi Shida, like Luffy kicking Hody to save Neptune, or his first transformation into Gear Fourth.
What Do You Mean, It's for Kids?: This is a show meant for all ages, but the high amount of violence wouldn't pass for a kids show in the States. The U.S. version of the series tried playing it straight by reducing most of the violence and language for any kids channel, including Cartoon Network, but after 4Kids dropped the license, Funimation averted this trope when they released it in its uncensored form and now has a rating of TV-14.
The Punk Hazard arc, full stop. Giant skulls. Dragons. Flying bird lady things. Gas mask men who are lamb people underneath. Centaurs. Giant kids in a nursery. Moving, talking blob who is the leader of said lamb people. Giant, frozen corpses. Franky's beetle-jaw hairstyle?
There have been islands in the sky (a habitat for giant birds with key-shaped beaks, along with bizarre fish such as "Skysharks"), a hypnotist that moonwalks everywhere he goes, a man who tried to turn the main characters into a giant wax sculpture, and snails as long distance communication. Our heroes include a rubber man, a skeleton with an afro, a Speedo-wearing cyborg, and a reindeer doctor. Many of these individuals gained their powers by eating a mystical fruit, which has also been shown to be able to be "eaten" by things like guns and swords.
Many fans were feeling downbeat about the series given the negative reception of the 4Kids adaptation. However, they were delighted when it was revealed by Funimation licensed the series in 2007 and made a more faithful adaptation. Even better received was the revelation nearly eight months later that they would actually re-release the first 143 episodes of the anime in their unedited version with a new dub.
Or at least quell the riot. Several veteran animators returned partway into Whole Cake Island, bringing back a bit of the quality seen in the first half of the series. While the quality's still nowhere near what is was and the pacing is still a nightmare, it's starting to cool down the fans complaining about the state of the anime.
The Anime's adaptation of the Wano arc takes this even further, and is easily the most consistently well animated arc in the entire series, arguably looking as good as some seasonal anime. While the less-than-a-chapter-per-episode pacing is still an issue, it's much easier to deal with thanks to generally more well done Adaptation Expansion and less obnoxious padding than prior arcs.
Many of the fans and critics mercilessly questioned the choices of the voice actors/actresses for the 4Kids dub, particularly David Moo/Sanji.
In Marc Diraison's case, the fans pitied him for being chosen to voice Zoro.
Alejandro Orozco is known to be one of the best voice Mexican dubbers of the modern era, however, his tone used to voice Usopp in the Latin American Spanish dub of One Piece in Netflix is considered as not good by the fanbase.
