Monkey D. Luffy/Misc.

Early Concepts
When drawing One Piece, Eiichiro Oda was heavily influenced by the manga Dragon Ball, and had the series in mind when designing his characters. Oda has said that when he was creating Luffy, he was thinking about "manliness", because Dragon Ball had already done all the things that a child could possibly be happy about.

Luffy was first featured as the main protagonist in the first pilot of One Piece Romance Dawn V.1 in the Shonen Jump specials showcasting upcoming artists, about a year and a half before One Piece began. He would remain as the main protagonist in the second release of Romance Dawn, Romance Dawn V.2 (featured in Weekly Shonen Jump magazine itself) and the final version Romance Dawn V.3.

Luffy's character changed throughout all three versions of Romance Dawn. Starting from Romance Dawn version 1, Luffy was much smarter than his final incarnation and while he had the power of the Devil Fruit, he did not seem to have any named attacks. He claimed to be a candidate for pirate and a Peace Main type of pirate. His background story was near enough identical to the final story released with Romance Dawn version 3, with a number of noteworthy differences. The major difference being that Higuma was absent from the story in this version. Another minor difference was that Shanks' arm was bitten off by a shark instead of a Sea King. In Romance Dawn V.1 there was also a panel that featured a Luffy as captain of his own crew. This is the only time an older version of Luffy has been drawn by Oda in regard to the One Piece storyline.

Version 2 of Romance Dawn featured a Luffy closer to the final version than Romance Dawn version 1. He now had a named attack (though it featured a different naming scheme to the final version) and lacked the intelligence he displayed in Romance Dawn version 1, however, it is arguable that he was less intelligent than his final design overall. His story, though still featured him eating the Devil Fruit, did not feature Shanks and instead Luffy got both his hat and the Devil Fruit he ate from his grandfather. Luffy remained a Peace Maine type of pirate in this version and was still promoting himself as a candidate for a pirate while seeking to join up with a crew.

In both versions, Luffy was missing the scar under his left eye, and he had a slightly different jolly roger. Apart from this the only difference in Luffy's overall appearance was the adaptation to suit the drawing style of each Romance Dawn. The most noteworthy change from each version was of Young Luffy, whose head and body shape, though remained roughly the same, was different enough to notice.

Anime and Manga Differences
In the anime, Luffy's past had a few cuts during its initial airing. The scenes that were cut include the scene where he stabbed himself under the eye to prove to Shanks that he was a man and all the of the scenes of Shanks giving Luffy juice, and Shanks making fun of Luffy for being a child, as well as some of the interaction between Shanks, Luffy and the rest of Shanks' crew. Although the One Piece: Episode of Luffy Special first animated the scene of Luffy stabbing himself under his eye, all of the aforementioned scenes were not seen in the anime until Episode 878.

In the manga, post-timeskip Luffy is capable of using Gear 2 maintaining it in a single part of his body, while in the anime, he shows no such difference, requiring his entire body once more to turn red and emit steam like previously.

In anime, when Buggy appeared again after Luffy beat him and when Zeff said he will cut one of his legs, Luffy showed fear on his face. But in manga he didn't show any fear.

Translation and Dub Issues

 * Though some translations dub his name as "Ruffy" or "Rufi", Oda himself made it clear that "Luffy" was the correct spelling of the name.
 * Oda has claimed that at the time of naming Luffy, he did so because he felt the name "Luffy" was right for his main character. Later Oda found out there is a Maritime term called a "Luff" and has insisted this is pure coincidence but one he was delighted by. Up until this point, this had previously been noted by fans and some considered it intentional.
 * In the Viz English manga, 4Kids and FUNimation dubs, the most common alteration seen to Luffy is the reference to his Devil Fruit, the Gomu Gomu no Mi, as the "Gum-Gum Fruit." The correct term would be the "Rubber Rubber Fruit," which has not been used outside the Odex version of the series (For example, Gomu Gomu no Fusen is translated as "Rubber Balloon"). This is, however, often considered an unfortunate necessity, as fitting "Rubber-Rubber" into the allotted animation "lip-flap" and time is nearly impossible without sounding rushed or otherwise ridiculous; "Gum-Gum," naturally, fits perfectly.
 * Other alterations in the 4Kids dub are mainly directed around the renaming of most of his attacks, most away from references to guns (such as the Gomu Gomu no Pistol, which becomes Gum-Gum Blast), but not traditional weapons (Gomu Gomu no Ono/Gum-Gum Axe). Other than attacks, Luffy is constantly the center of attention for the removal of blood in battles against foes. All of these are common censorship edits made for American TV. With the recent changeover of the dubbing company, FUNimation took a more relaxed approach to editing, and retained the firearm references, as well as a gratuitous level of blood shown. By Episode 177, the anime appears to be fully uncut.
 * In the book The Anime Encyclopedia: A guide to Japanese animation since 1917 (2001), there was a short article about One Piece. In it there were 3 mistakes concerning Luffy; his age was written as 16, his name was spelled Rufy and he was written to have saved Shanks' life instead of the other way round.
 * Luffy's popular title Fifth Emperor (５番目の皇帝) contains a linguistic nuance that's often omitted in English Translations, creating a degree of confusion among fans. In japanese, the phrasing (Gobanme no Kōtei) implies that Luffy is a Fifth pirate adjacent to the Yonko without being considered one of them. However, Yonko (四皇 lit. Four Emperors) is typically translated as "Emperor" in english releases, removing this sense of differentiation. This has led to Luffy incorrectly being called "the Fifth Yonko" in some fan-made translations.

Trivia



 * Luffy is the first Devil Fruit user to appear in the series, as well as the first Paramecia-type user.
 * Luffy is also the first character in the series to be seen eating a Devil Fruit.
 * It wasn't until Chapter 1044 that it was revealed that Luffy's Gomu Gomu no Mi Devil Fruit was originally classified as the Mythical Zoan-type Hito Hito no Mi, Model: Nika, officially making him the first Zoan-type user in the series, as well as the first Mythical Zoan-type user. In a twist of irony, this technically makes him the user of both the most common type of Devil Fruit (Paramecia) and the rarest sub-type of Devil Fruit (Mythical Zoan)
 * Like many characters, Luffy has a distinct laugh ("shishishi").
 * At the age of 19, Luffy is the youngest member of both the Worst Generation and the Four Emperors.
 * Luffy has the lowest bounty among all the Four Emperors, past and present.
 * Luffy is the only Emperor to not serve under another Captain, although he wanted to join the Red Hair Pirates when he was younger.
 * Luffy, Sanji, and Usopp all claim to have never been sick, and thus do not know what it feels like.
 * Luffy's participant number at the Corrida Colosseum (as "Lucy") is 0556. That number can be explained with the first two digits taken from Luffy's birthday, May 5; and the latter two, 5-6, being pronounced go-mu which is related to Luffy's Devil Fruit.
 * Luffy's participant number at the Corrida Colosseum also corresponds to the chapter where he first arrived at Marineford to rescue his brother, Portgas D. Ace from his execution.
 * Luffy ranks first place in every fan poll. This also means that he is the only character to have consistent placements.
 * Although he is male, Luffy is voiced by a woman in both the English (including the 4Kids and Funimation versions, but excluding the Odex version) and the Japanese versions of the anime.
 * Luffy shares many similarities with Son Goku, the main character from the Dragon Ball series who features a childlike and naïve personality, messy black hair, and a gluttonous side. Luffy's surname, "Monkey" is a reference to Goku's Saiyan tail, which resembles monkey tail. These similarities are fitting since Oda was inspired by Dragon Ball while creating One Piece.
 * Luffy is also similar to the late Pirate King, Gol D. Roger, as they both have the initial D. in their names, had friendly relations with their respective crews and rivals, can use all three forms of Haki (and can imbue their attacks with Haoshoku Haki), can hear the Voice of All Things and once wore the famous straw hat.
 * Luffy's powers are quite similar in nature to that of DC Comics hero Elongated Man, mostly because they were both obtained after the consumption of a special fruit.
 * Luffy shares some things with the other members of the Worst Generation:
 * He and Killer are the only known members to be not named after a real-life pirates.
 * He, Roronoa Zoro, and Eustass Kid are the only known members who can use Haoshoku Haki.
 * He, Marshall D. Teach, and Trafalgar D. Water Law are the only known members that have the initial D. in their names.
 * He and Jewelry Bonney are the only known members to be children of other wanted criminals (Revolutionaries in both cases), with Luffy being the son of Monkey D. Dragon and Bonney the daughter of Bartholomew Kuma.
 * Two of Luffy's abilities demonstrated in a non-canon anime filler arc are now part of the official manga canon. The first is the Voice of All Things that was first seen in the Warship Island Arc and was later introduced officially in the Fish-Man Island Arc. The second was Luffy's ability to grow giant which was first seen in the Z's Ambition Arc (with the aid of Lily Enstomach's Devil Fruit abilities), which was later added officially as part of one of Luffy's Gear 5 techniques that was first seen in the Wano Country Arc.
 * Oda has a personal policy that Luffy can never be shown on the cover of a magazine that is not Weekly Shonen Jump. In cases where One Piece provides the cover for a spin-off magazine, Luffy will be absent.

 * A fan asked Oda why Luffy doesn't kill his enemies, and Oda answered that it is not a question of morality so much as a matter of punishing the villains for their crimes because he feels that killing the villains lets them off too easily, whereas he considers letting them live to see their dreams ruined a far more fitting punishment.
 * A fan asked Oda if Luffy's penis could stretch, and Oda answered that it could.
 * A fan asked Oda if he could become a rubber human if he ate Luffy, and Oda answered that he would get food poisoning.
 * A fan asked Oda why Luffy doesn't have a lot of thought bubbles, and Oda answered that when drawing Luffy, he trying to make him very simple and straightforward about what he wants to be and how he feels, which is why out of all the main characters, Luffy has the least number of thought bubbles, since he acts and says what he wants to do rather than think it.
 * A fan asked Oda why he gave Luffy a rubber Devil Fruit, and Oda answered that he picked a ridiculous ability to allow him to fool around with Luffy for so long, no matter how serious will be the plot gets in his manga.
 * A fan asked Oda who would win if Luffy, Eustass Kid, and Trafalgar D. Water Law played a game of rock-paper-scissors, and would it be Luffy because he can see the future. Oda answered that while Luffy can indeed see the future and could do that to win, he hates cheating, so Oda doesn't think Luffy would look into the future. At the end, Oda added that they do not get along very well with each other, so they would end up fighting no matter who wins.
 * Luffy's favorite food is all kinds of meat. Also, his favorite food from Wano Country is oden.
