History EarlyInstallmentWeirdness / OnePiece

* Kuina dying by falling down some stairs in Zoro’s backstory doesn’t mesh very well with later One Piece. [[TruthInTelevision While it’s a shockingly sudden and very realistic]] way for someone to die, One Piece characters- up to and including children- eventually came to be well known for being MadeOfIron as the series went on. So for someone who was stronger than the already-abnormally-strong kid Zoro to just fall down some stairs and die… it would seem ridiculous happening to any character today, even if they were just a child.

* At the beginning of the series, the very existence of Devil Fruits was heavily questioned in the setting, with many not even having heard of them at all. As the story progressed, it has been shown that there are many prominent people with Devil Fruit powers, such as high-ranking members of the government and many of the most powerful and well-known pirates. Additionally, information spreads easily in the One Piece world, what with the existence of cameras and video phones. As the series has progressed, it's become incredibly unlikely that anyone in the One Piece world doubts the existence of Devil Fruit.

** When Luffy carelessly pokes open the holes in his Straw Hat that Nami just sewed shut after his fight with Buggy, she punishes him by poking his face with her needle, explaining that hitting him wouldn't actually work. Later in the story, she'll dish out plenty of slapstick on Luffy despite his supposed immunity to blunt force like fists (at least without [[KiAttacks Color of Armament Haki]]).
** When Sanji first met Luffy, he was naive about Devil Fruits and their side effects; Zeff even had to tell him that Devil Fruit users can’t swim, and thus Sanji had to rescue Luffy from the ocean after the latter defeated Krieg. Later, in Thriller Bark, Sanji is revealed to have read about Devil Fruits in his childhood in the North Blue, and states that only the Clear Clear Fruit's power would be worth losing the ability to swim. This means that Devil Fruits are well-known enough to have their own reference materials in the world of One Piece, making the earlier examples of people doubting their existence even weirder.

* Laugh Tale was originally called Raftel in English before its meaning was revealed, and it was implied to simply be at the end of the Grand Line with only Gol D. Roger-level pirates able to reach it. Post time-skip, it's revealed that reaching Laugh Tale isn't just following the Grand Line to the end but is somehow impossible to find without the Road Poneglyphs to create a map.

** One of the first of Kaido's underlings seen is a cyborg named Scotch. He sticks out like a sore thumb compared to the other Beasts Pirate lieutenants because nearly all of them follow a theme of possessing Zoan Devil Fruit powers; in particular all of Kaido's top personnel have Ancient model Zoans that allow them to turn into prehistoric animals, while Scotch has no apparent Devil Fruit powers at all despite being important enough to be in charge of guarding one of Kaido's favorite islands.

* During the East Blue, [[TheGreatestStoryNeverTold the Straw Hats leaving an island with only one or two people aware of their heroics]] was almost a [[OnceAnEpisode once-per-arc]] gimmick. This was pretty much dropped from [[Recap/OnePieceArlongArc the Arlong arc on]](when Nezumi reporting Luffy's exploits to the Marines put Luffy on the Marines' radar and got him his first bounty), where they're hailed as national (if unofficial) heroes in pretty much every kingdom they visit.

** Even the very first ''mention'' of Devil Fruit's, where Lucky Roux explains them to a shocked Luffy after he accidentally eats the Gum-Gum Fruit, is this after ''Anime/OnePieceFilmRed'', which introduced Uta, Luffy's childhood friend, Shanks' adopted daughter, and the user of the Song-Song Fruit. One needs to seriously stretch their imagination to believe Luffy would have no familiarity with what the Fruits were beforehand, especially given how close he and Uta are shown to have been.

* When “Haki” was introduced in the series, it had little to no visual cues whenever a character used it. As the series progressed, Haki became a standard ability for any self-respecting strong individual in the New World, and it gained visible effects on usage: Color of Armament has the user coating their bodies with a black material, Color of Observation shows the user’s eyes glowing upon activation, Color of the Conqueror shows a monochrome blast in the anime, and when two people with Conqueror's Haki clash, black lightning surges. The original usage of Conqueror's Haki, by Shanks in chapter 1, was also different: the Sea King he used it on got scared and ran away, but after Haki is properly introduced, victims of Conqueror's Haki are usually knocked unconscious.

** One of the first of Kaido's underlings seen is a cyborg named Scotch. He sticks out like a sore thumb compared to the other Beasts Pirate lieutenants because nearly all of them follow a theme of possessing Zoan Devil Fruit powers; in particular all of Kaido's top personnel have Ancient model Zoans that allow them to turn into prehistoric animals, while Scotch has no apparent Devil Fruit powers at all despite being important enough to be in charge of guarding one of Kaido's favorite islands.
* In Fishman Island, Jimbei claims that once a pirate's bounty surpasses 300 million, it usually doesn't go up any further, with Luffy's jump from 300 million to 400 million being an exception. Luffy's bounty has risen ''three times'' since then- to 500 million after Dressrosa, 1.5 billion after Whole Cake Island and 3 billion after Wano.

** Haki, in it's earliest form, appears to have been intended as a type of psychic and/or telekinetic power. This is best seen when Sentomaru is able to fling Luffy around with no problem in Sabaody, and then again during Marineford when the Admirals stopped Whitebeard's shockwave from hitting the execution platform by gesturing with their arms and concentrating.

* Zoro's [[NoSenseOfDirection terrible sense of direction]] wasn't present for the first few arcs. This becomes noticeable in the [[Recap/OnePieceKuroArc Kuro Arc]], where he and Luffy are late to the confrontation with the Black Cat Pirates. While Luffy, who also has a bad sense of direction is late due to getting lost, Zoro's excuse is just that he got stuck in an oil patch. After getting un-stuck, he has no issues arriving at the scene.

** The taste of Devil Fruits themselves. Nowadays, they're universally treated as tasting disgusting, but in the early chapters, they were treated as tasting mediocre at worst. When a young Luffy ate the Gum-Gum Fruit, he had no real issues with eating it, simply telling Shank's crew that it didn't taste that good. And when a young Buggy accidentally ate the Chop-Chop Fruit, he had no reaction to its taste whatsoever (though in the latter's case, it's possible that since he swallowed it whole, he didn't even have a chance to taste it). To be fair, Luffy will eat practically anything even if it tastes bad. See: the cherry pie in chapter 223.

** Speaking of Haki, [[spoiler:Ace being shocked that Teach can touch him now comes across as this because it's since been revealed to be a common for New World pirates to be able to touch Logia Fruit users using Haki, and Teach is an experienced New World pirate. The point is further hammered home by Teach commenting that Ace is probably not used to his enemies being able to hit him. The Ace novels makes it even weirder since they establish Ace himself developed Armament Haki to fight Vice Admiral Draw. There's also no indication Ace could use Haki at the time since he didn't even try to use it on Blackbeard, opting to fight with his Devil Fruit exclusively]].

** The first of the Big Mom Pirates to appear such as Bobbin, Pekoms, and Tomago, have no biological connection to Big Mom outside of being her subordinates despite calling her "mama", while basically every other member of her crew introduced after was either her biological child or a homie created from her power.

** Kaido was also a LOT bigger when introduced, appearing roughly as big or bigger than an Elbaf giant. Later, his height is comparable to Big Mom and he's actually shown to be a hair '''shorter''' than Gecko Moria, who's only about knee high to an actual giant.
** One of the first of Kaido's underlings seen is a cyborg named Scotch. He sticks out like a sore thumb compared to the other Beasts Pirate lieutenants because nearly all of them follow a theme of possessing Zoan Devil Fruit powers; in particular all of Kaido's top personnel have Ancient model Zoans that allow them to turn into prehistoric animals, while Scotch has no apparent Devil Fruit powers at all despite being important enough to be in charge of guarding one of Kaido's favourite islands.

** Kaido was also a LOT bigger when introduced, appearing roughly as big or bigger than an Elbaf giant. Later, his height is comparable to Big Mom and he's actually shown to be a hair '''shorter''' than Gecko Moria, who's only about knee high to an actual giant.

* Big Mom. When she was first introduced (in Fish-Man Island, not her silhouette) looked almost like a cephalopod, had acidic saliva, and was seen casually '''eating''' a member of her crew, but when she was formally introduced, she not only looked completely different, but the saliva thing was gone and she consumed others' lifespan with her Soul-Soul Fruit rather instead of literally eating them. Her personality also changed: on Fish-Man Island she was intrigued or even impressed by Luffy challenging her, and agreed to shift the island's debt to him, but by the time Tottoland came about, she had displayed absolutely none of this honorable behavior, being a bat-shit crazy loon who dismissed Luffy as basically nothing and was enraged that he and the Sanji retrieval team would dare oppose her.

* Given the manga was only supposed to run for 5 years before Oda expanded the story, this was bound to happen. In the beginning, the Grand Line was a crazy, mysterious ocean barely anyone could survive. Later, it's established not only that plenty of perfectly normal people are native to the Grand Line, but pretty much any pirate worth his salt can navigate it. Then, it turns out there's a previously unheard of second half to the Grand Line known as the New World, while the "crazy mysterious" first half is now known as Paradise.

* At the beginning of the series, the very existence of Devil Fruits was questioned and doubted by characters. Some of whom had never heard of them, some of whom didn’t believe in them at all. They were at least considered a myth. As the story progressed, it has been shown that there are many prominent people with Devil Fruit powers, some of whom are high-ranking members of the government/military. And in a world of famous pirates, many of the most powerful and well-known have Devil Fruit powers as well. The idea that people don’t know they exist, seems impossible. Now, the encounter rate for a Devil Fruit user may be low outside of the Grand Line. It might be very unlikely that most people would meet a Devil Fruit user. But it makes sense that they would’ve heard of Aokiji for example, and his amazing ice powers. Especially in a world where cameras and telephones exist. The story also shows us that information about serious events are capable of spreading fairly easily. For example, everyone who the Straw Hats had met up until that point in the story, read about the events in Marineford. But even before Marineford, it should’ve been impossible to keep a secret about a man who can turn into a giant Buddha statue. Everyone would know. As the series progressed, the idea of Devil Fruits as a myth or well kept secret, has steadily eroded away.
** Alvida was the first person to make the claim that Devil Fruits were a myth, however she managed to find and consume a Devil Fruit in no more than A WEEK of meeting Luffy, and didn't even go to the Grand Line to do it. Which means somewhere between getting punched into the sky, and meeting up with Buggy, she just HAPPENED to stumble across a "super rare" Devil Fruit.
** Buggy's backstory. The pirate crew he was in as a boy wasn't sure Devil Fruits existed and he was even able to get away with stealing one by eating a fake and pretending it didn't do anything and Devil Fruits themselves were a myth. The dubiousness of that besides, given how common Devil Fruits became later on, we eventually learned that said crew was that of the Oro Jackson, aka Gol D. Roger's pirate crew, a group that should have been encountering Devil Fruit users left and right. But then again, who said they were already in the Grand Line during the flashback, and plus, it should be over 24 years before the present time, so these factors justify this example a little bit.
** A retcon about Sanji also included an extra tidbit about availability of information on Devil knowledge. When he first met Luffy and the others, he was as naive about Devil Fruits and their effects as most of the other characters in the beginning. Zeff even had to tell him that Devil Fruit users can’t swim. Later once Devil Fruits are established more commonly in the series, Sanji is retconned to having not only have known about Devil Fruits, but have an intimate knowledge of them thanks to a book he read! Meaning that Devil Fruits are so common as to have their own reference materials in the world of One Piece, making the earlier examples of people doubting their existence even weirder.

* Luffy's fight with Zoro at Whiskey Peak. It's been made clear lately that Luffy would do anything to protect his crew and he believes in them completely, so it seems kind of odd now that he instantly attacked Zoro for supposedly killing a bunch of strangers who fed them (who were actually assassins) without even asking him about it first.
* The death of the often forgotten minor character Pudding Pudding in the Arlong Park Arc. Considering an equally unimportant guy like Caribou from the Fish-Man Island Arc can survive having his ship destroyed at the bottom of the ocean, it's kind of odd that Arlong was actually allowed to kill Pudding Pudding (in similar fashion as Caribou to boot, since he sent his ship to the bottom of the sea).
* When a type of power called “Haki” got introduced in the series, said power presented itself as more of a concept with little to no visual cues whenever a character used it, as the series progressed Haki became a standard ability for any self-respecting strong individual in the New World and more visible effects started being attributed to the several forms on Haki usage: Color of Armament (makes the person physically stronger) has the user coating their bodies with a black metallic second skin, Color of Observation (makes the person very agile, with great perception and great sight) shows the user’s eyes often glowing upon activation, Color of the Conqueror (mysterious form with several unknown properties, albeit an obvious one is overpowering will) shows a monochrome blast being activated and when users of the same ability clash, a black lightning shock will surge. The original usage of Conquerors Haki by Shanks was also different, it showed the Sea King get scared and run away while later victims were knocked out completely. Observation Haki originally had seeing glimpses of the future as a normal thing, with Luffy displaying this in Marineford before he even knew what Haki '''was''', but this is later said to be an extremely advanced and rare technique.
** Speaking of Haki, [[spoiler:Ace being shocked that Teach can touch him now comes across as this because it's since been revealed to be a common thing in the New World for people to be able to touch Logia Fruit users using Haki and Teach is an experienced New World pirate. The point is further hammered home by Teach commenting that Ace is probably not used to his enemies being able to hit him. The Ace novels makes it even weirder since they establish Ace himself developed Armament Haki to fight Vice Admiral Draw. There's also no indication Ace could use Haki at the time since he didn't even try to use it on Blackbeard, opting to fight with his Devil Fruit exclusively]].
** Haki also goes from a rare and mysterious ability to something basically everyone in the New World can use (except Conqueror's Haki), which makes it all the weirder that New World level characters who appeared before the timeskip didn't seem to use it. Mihawk, Doflamingo, Jimbei, Ace, and some Marines who were all later confirmed to be Haki users never displayed any of its abilities pre-timeskip despite later showing to be high level users, while Crocodile and Moria, warlords supposedly among the strongest and most infamous Pirates not connected to the Four Emperors, suddenly seem like small potatoes compared to virtually all the New World characters since both are shown to be incapable of using even basic Haki.
* Big Mom. When she was first introduced (in Fish-Man Island, not her silhouette) looked almost like a cephalopod, had acidic saliva, and was seen casually '''eating''' a member of her crew, but when she was formally introduced she not only looked completely different, the saliva thing was gone and she was specifically shown to consume others lifespan with her Soul-Soul Fruit rather than eat them literally.

** The first of the Big Mom Pirates to appear such as Bobbin, Pekoms, and Tomago, were not connected to Big Mom outside of being her subordinates despite calling her "mama", while basically every other member of the crew introduced after was either her biological child or a homie created from her power.
