History YMMV / OnePiece

** Sanji started gaining this status after ''One Piece Film: Z'' saw him getting a little ''too'' excited at the thought of watching a [[FountainOfYouth de-aged]] Nami grow up. Later on, the Whole Cake Island Arc would see him falling in love with Pudding, a 16-year-old girl, despite him being 21.

** As of 2023, the manga has reached over '''1100 chapters''', with no end in sight (although Oda did declare that it is officially in the "Final saga" now). Creator/VizMedia 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.

** A good handful of fans, whether jokingly or otherwise, call Boa Hancock a pedophile for falling in love with Luffy when he was 17 years old while she was ''29'', making it a ''12-year age gap'' between the two.

** A lot of fan art from the Japanese fandom tends to play up Uta's [[ImpliedLoveInterest (implied)]] feelings towards Luffy to [[{{Yandere}} yandere]]-tier obsession, likely due to the fact that [[spoiler:Uta was especially determined to keep Luffy trapped in Uta World, even going as far as to ask him to quit being a pirate and stay with her while lingering around Luffy's unconscious body in the real world.]]

* BestKnownForTheFanservice: OK, maybe not quite ''best''-known, but one you go past the over-the-top battles and wacky comedy, what is the next-most well-known thing about the series? That's right, the enormous boobs, tiny waists and skimpy outfits possessed by 90% of the female cast.

* OneSceneWonder: Many [=SMILE=] users appears for just one single scene or even as a background character, but many of them have such goofy and absurd designs that gain the attention of many fans. Particularly Four Tricks, Hamlet and Briscola ([[GermansLoveDavidHasselhoff the latter is beloved by Italians due to being named after an Italian card game]])

** Opening 26, [[https://www.youtube.com/watch?v=YFbno_aPm0w "UUUUUS!"]] is commonly regarded to have the best visuals out of many of the openings put on the show. It's vibrant colors and jumpy animation, with amazing transitions and breathtaking visuals give it a unique feel differing from other openings.

** Arlong became a bit of one after an obviously-fake leak came out saying that Arlong would make a reappearance in the story, having undergone a HeelFaceTurn and become a Marine Admiral. The leak also claimed that he would be capable of utilizng a unique type of Haki called "Blue Haki."

** You can't one up a bastard-8 foot plus tall knight-marine-Godfather-pirate who kills people by touching them named Crocodile...unless you are a silent-8 foot plus tall superstrong gangster-pirate-monk who is also a sword named DAZ BONES. He's like Raven from [[Franchise/{{Tekken}}, only bigger, stronger, a pirate, has no need for weapons, and has the greatest name ever hands down. His loss or rather, both of their losses, lost the Straw Hats fans.

* MemeticMolester: Blackbeard took Bonney hostage soon before the timeskip and said he wanted her to "be his woman." With the revelation that [[spoiler:Bonney is chronologically just ''12 years old'' in the present, meaning that she was only '''10''' when he made this comment, fans have, jokingly or otherwise, called Blackbeard a pedophile]].

** Whitebeard[[spoiler:'s death, but not without him yelling that THE ONE PIECE IS REEEEEEAL!!!]] is one of the biggest memes in the series, and also is a fitting display of the series' themes.

* MemeticMolester: Blackbeard took Bonney hostage and said he wanted her to 'be his woman'; with the revelation that [[spoiler:Bonney is chronologically only ''twelve years old'', fans have, jokingly or otherwise, called Blackbeard a pedophile]].

** Whitebeard's vicious beatdown of Akainu after he had just [[spoiler:murdered Ace.]] Admit it, you were ''cheering.''

** 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 HeroicSacrifice ''twice'' and surviving). The series managed to buck the trend by killing off [[spoiler:Ace and Whitebeard]] at Marineford, but later developments, like [[spoiler:Sabo surviving his supposed death in Luffy's flashback, Pound coming back in a cover story and Kin'emon not dying after Kaido ran him through]], prove that this trend hasn't quite gone away.

** [[spoiler:Both Ace and Whitebeard die in Marineford.]]

** [[spoiler:Ace tearfully dying in Luffy's arms at Marineford.]] It's the first major unambiguous death scene outside of flashbacks in a story somewhat infamous for {{Disney Death}}s.

** While it's easy to feel sorry for Luffy as [[spoiler:his brother Ace is killed by Akainu, many fans don't feel the same way for Ace himself. 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, which caused him plenty of grief during the first half of the arc, he stops escaping because Akainu has insulted Whitebeard. Despite his allies, including [[IdiotHero 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 he not only disregards the sacrifice of the dozens if not hundreds of his allies that died for his sake, but gets himself killed in a glaring case of IdiotBall, rendering all their efforts pointless.]]

** The 4Kids dub is this for some as a way to heckle at, and the addicting rap.

* LoveToHate: [[SharkMan Arlong]], [[DiabolicalMastermind Sir Crocodile]], [[AGodAmI Eneru]], [[SmugSnake Spandam]], [[KnightTemplar Admiral Akainu]], [[EvilCounterpart Blackbeard]], [[MadScientist Caesar Clown]], [[AgentPeacock Doflamingo]], and [[MadScientist Saint Saturn]] are many things, but forgettable villains aren’t one of them.

** 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, despite nothing similar happening to any of the other people Law dismembered with his powers.

* WhatDoYouMeanItsForKids: This is a Shonen manga in the vein of ''Manga/DragonBall'' (Creator/EiichiroOda's main inspiration for the series) that's supposed to be meant for all ages, but it surprisingly features a huge amount of adult content that seems to push every single boundary of the Shonen genre to the extreme, what with insane amounts of extreme violence (including all sorts of extremely bloody and messy fights), some sexual material, foul language beffiting of a sailor, [[NightmareFuel frightening imagery]], a gigantic plethora of [[TearJerker surprisingly incredibly heartwrenching moments]], racism, slavery, torture, and genocide that would make ''Literature/ASongOfIceAndFire'' look like a picnic, [[CompleteMonster some truly vile and heinous villains]], one of the most horrific and utterly evil totalitarian governments in all of fiction being largely responsible for [[CrapsaccharineWorld all the suffering in the series' otherwise optimistic setting]], and so much more. It's telling that the U.S. version of the anime adaptation tried to make it kid-friendly 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 the anime in its uncensored form, now with a well-deserved TV-14 rating.

** Ryokugyu/Aramaki was the second of the two new Admirals ot be introduced after the TimeSkip, and unlike Fujitora, who put in an impressive showing, Ryokugyu didn't. While he did curb stomp both King and Queen, it's made abundantly clear that they were both fighting with a massive handicap, as they were still injured and exhausted from their fights with Zoro and Sanji, respectively, something that Ryokugyu himself points out. He then proceeds to fight against Yamato, Momo and the surviving Akazaya Nine, none of whom (except for Yamato, who can stall Kaido for a while.) are particularly challenging opponents for an Admiral. Then, finally, before that fight can conclude, he is sent running when Shanks uses his [[FanNickname WiFi Haki]] to intimidate him from clear across the country. All of this has led fans to brand him as a coward who runs from fights where he doesn't have an overwhelming advantage, and declare him the weakest Admiral in the series by far.

** Giants are seen as a powerful race, and Big Mom believes she would have become Pirate King if she's gained Elbaf's allegiance, but more often than not, their imposing size simply serves to hype up their opponents who easily defeating them.[[note]]Marineford-Luffy can easily defeat them, meaning any New World pirate worth their bounties aren't going to have a hard time defeating them.[[/note]] Special mention goes to the Numbers, who are effortlessly trounced despite being hyped up as Ancient Giants like Oars.

** Eustass Kid was an ally of the Straw Hats for most of Wano, in which he did fight against Big Mom with Law. This, combined with his punk rock aesthetic and sheer cool factor, have made many people forget that he's arguably the most villainous out of the Supernovas. His bounty by the time of Sabaody was higher than Luffy's because of the sheer carnage he wrought upon the islands he visited. [[spoiler: In chapter 1079, when Kid is defeated by Shanks and his ship is destroyed, many felt sympathy for him. Despite the fact that he wanted to fire upon Elbaf and Shanks' fleet, which would have killed dozens or more people if not stopped.]]

* HarsherInHindsight: Remember when Blackbeard almost took Bonney as his sex slave? It gets much, much darker when it's revealed that [[spoiler:Bonney was actually ''[[YoungerThanTheyLook 10 years old]]'' at the time of this encounter.]]

** Sanji was always dunked on by a good handful of fans. However, what is perhaps the straw that broke the camel's back is when the Egghead Arc saw him getting knocked out by Saturn's DeadlyGaze and rendered immobile and helpless while supposedly weaker individuals like Bonney and [[spoiler:Kuma]] were seemingly unaffected by it or able to snap out of it. The fact that Oda once jokingly said to Hirata, Sanji's VA, that Sanji will no longer have any highlight scenes in the future is not helping matters.
