"Monkey D. Luffy" has been featured, meaning it was chosen as an article of interest.
Early One Piece
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 PieceRomance 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 note worthy change from each version was of Young Luffy, whose head and body shape, though remained roughly the same, was different enough to notice.
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 Second 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.
Luffy appeared in a Shonen Jump special, where Enel attacks Tokyo and Odaiba. Goku arrives to fight Enel and Luffy appears to help him. Luffy and Goku make an attack called "Gomu Gomu no Kamehameha" and they destroy Enel.
Luffy and other characters also appeared in "Cross Epoch" with Dragon Ball characters. In this story, after Luffy falls from a cliff, Goku orders the Flying Nimbus to save Luffy from the fall, and then, he rides the Flying Nimbus until they arrive at the tea party. Being able to ride the Flying Nimbus, in the universe of Dragon Ball, means that Luffy is pure of heart.
In Episode 56 of Yakitate!! Japan, there is a parody of One Piece where Kuroyanagi turns into a "Tenobi Man" as a reaction from trying Azuma's Japanese-Style Ja-pan dumpling. To this effect, he dons a straw hat and starts stretching his arms like rubber to unbelievable lengths like Monkey D. Luffy.

He also wears Luffy's pre-timeskip attire. After two years of beating Piccolo from Dragon Ball, Gintoki transforms into the Super Saiyan Goku and returns to the Jabondy archipelago to join the "World Chunin Hunter Hero Exam".
In another episode, Gintoki reads fan mail in which one fan asks what the goal of Gintama is yet Gintoki himself doesn't know. So they have decided (as a joke) the goal would be Gintoki becoming the king of the samurai referencing Luffy's journey to become the Pirate King. Also Gintoki is shown in a picture wearing Luffy's former attire also while being on the Thousand Sunny with the Lion head replaced with Elizabeth's.

In the 2017 season of Gintama, one of the episodes started by ripping off the entire One Piece introductory sequence. It included eating the Kuru Kuru no Mi (Wavy-Wavy Fruit in English) which is a Devil Fruit that physically looks like Luffy's. However instead of giving any superpowers, the fruit gave Gintoki's signature wavy hair. He also changed his goal to finding the Pirate King's treasure and become the "King of the Nouveau Riche" which is a more blatant reference to Luffy's goal from the previous parody.
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 lead to Luffy incorrectly being called "the Fifth Yonko" in some fan-made translations.
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 often recalls his crew members in the order of them joining the crew: "Zoro, Nami, Usopp, Sanji, Chopper, Robin, Franky and Brook."
Luffy currently has the highest known active bounty excluding the Yonko.
Luffy ranks first place in every popularity poll.
Luffy is very similar to Son Goku from Dragon Ball, being the main character, being very childish and naive, having messy black hair and eating too much food. These similarities are fitting since Oda was inspired by Dragon Ball while creating One Piece.
Luffy and his powers are similar to the DC Comics heroes Plastic Man and Elongated Man. Like Plastic Man, his signature colors are red and yellow, he has black hair and stretches. Like Elongated Man, his powers were obtained by the consumption of a special fruit.
The author of the manga One Piece named Eiichiro Oda has said: "when drawing Luffy, I try 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, he has the least number of thought bubbles, since he acts and says what he wants to do rather than think it".
Oda explains that it is not a question of morality so much as a matter of punishing the villains for their crimes - 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.
Luffy's birthday, May 5, in Japan is known as 'Children's Day' (こどもの日,Kodomo no Hi?), a reference to his childish character. He shares his birthday with Demaro Black.
A fan asked Oda if Luffy's penis could stretch, and Oda answered that it could.
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.

Luffy also likes ice cream, the same as Usopp, Chopper, Robin, and Brook.

Luffy's favorite type of island and season is anywhere where there's meat.
Luffy's specific numbers are 01 and 56 (5=Go - 6=Mu).
