I don’t wanna conquer anything. It’s just that the person with the most freedom on the sea is the pirate king.
Monkey D. Luffy, also known as "Straw Hat Luffy" and commonly as "Straw Hat", is the founder and captain of the increasingly infamous and powerful Straw Hat Pirates, as well as the most powerful of its top fighters. He desires to find the legendary treasure left behind by the late Gol D. Roger and thereby become the Pirate King, which would help facilitate an unknown dream of his that he has told only to Shanks, his brothers, and crew. He believes that being the Pirate King means having the most freedom in the world.
Born in Foosha Village, Luffy is the son of Monkey D. Dragon, the leader of the Revolutionary Army, and the grandson of the Marine hero Monkey D. Garp,, where their family carries the initial of D. At age 7, Luffy accidentally ate the Gomu Gomu no Mi, which turned his body into rubber. Shanks also gave Luffy the very straw hat that has become Luffy's signature accessory, having gifted it to the boy as part of a promise for them to meet again someday after he became a great pirate. Growing up on Dawn Island under the care of Curly Dadan, Luffy befriended and became sworn brothers of the late "Fire Fist" Portgas D. Ace and Revolutionary Chief-of-Staff Sabo.
Luffy has gone up against numerous global powers around him, starting with fighting the most powerful pirates in the East Blue and moving to clashes against the Marines, Seven Warlords of the Sea, Cipher Pol, World Nobles, and even the Four Emperors of the Grand Line, emerging victorious in a majority of these battles. He invaded and indirectly caused the annihilation of Enies Lobby, escaped the impregnable Impel Down, and was a focal figure in the Summit War of Marineford. He has also either defeated or befriended seven of the eleven known past or present Warlords prior to the organization's dissolution. Furthermore, Luffy has invaded the territory of the Four Emperors on multiple occasions and eventually managed to defeat one. Luffy's accomplishments and heritage have caused him to be labeled as a "Dangerous Future Element" while in the process gaining a reputation for being "reckless" and, in some cases, "insane," earning the wrath of Fleet Admiral Sakazuki, the Marine Headquarters, and even the World Government.
Luffy is a young man of average height with shaggy black hair, round black eyes, and a slim muscular build. He is renowned for his trademark straw hat (from which he gets his nickname "Straw Hat Luffy"), which was lent to him when he was young by the legendary pirate captain, "Red-Haired" Shanks, who in turn received it from Gol D. Roger. He wears blue shorts with cuffs, sandals, and a sleeveless red vest. Luffy also has a scar with two stitches underneath his left eye, which he earned as a child by stabbing his face to show Shanks that he was tough enough to be a pirate. He was severely wounded by Akainu in the Summit War of Marineford, leaving a large X-shaped scar on his chest.
Similar to most of his male crewmates, Luffy has the same outfit throughout most of the series. Luffy will often wear a different outfit to suit the climate of an island (such as a hooded parka on Drum Island or desert robes in Arabasta) but will switch back to his trademark red vest and blue shorts after the adventures on that island are over. Despite this, he will wear his usual outfit in different colors and has been known to sport other miscellaneous items on his person from time to time like in Thriller Bark and Sabaody Archipelago. According to Eiichiro Oda in 37 Volume SBS, Luffy does not know how to dress stylishly so sometimes he is advised on how to dress by more fashionable team members, Nami, Usopp, Sanji, and Robin.
After those two years, a few things have changed. He has grown slightly taller and is shown to be significantly more muscular due to his training. This can be seen in his slightly thicker neck, more pronounced deltoids, and a better-defined chest, which shows the X-shaped scar he received by then-Admiral Akainu covering most of it. His usual attire is mostly the same as it was two years ago, but instead of a vest, Luffy wears an open, long-sleeved red cardigan with four buttons, with a yellow sash tied around his waist (somewhat reminiscent of Gol D. Roger's outfit).
Due to Luffy's increasing notoriety in addition to the increasing strength of his foes, after the timeskip he finds himself more often dressed in disguises to mask his identity, with varying levels of sophistication. Despite this, he still never loses his trademark straw hat and instead opts to at times cover it with other headwear.
As one of the Four Emperors, and at the young age of 19, Luffy is one of the four most powerful pirates in the world. He captains the Straw Hat Pirates, holding the greatest authority over a mighty and diverse crew consisting of several infamous members, many of whom are extremely powerful in their own right. Luffy has a tremendous amount of influence over his crewmates, so much so that they all trust him with their lives, despite his reckless behavior and, in some cases, even because of it.
Luffy is a fierce and formidable combatant who can invent extremely creative fighting techniques even during intense battles and has gone through harsh and rigorous training ever since he was a child. He has been taught by two legendary figures, his grandfather Monkey D. Garp, the "Hero of the Marines", and Silvers Rayleigh, the retired first mate of the Pirate King's crew. Despite acting goofy and eccentric most of the time, Luffy has proven to be a natural born leader.
When he was 7 years old, Luffy unwittingly ate the Gomu Gomu no Mi, a Paramecia-type Devil Fruit, after finding it in a chest owned by the Red Hair Pirates. It gives his body the properties of rubber, allowing him to stretch, bounce, bend, twist, and inflate any part of his body. Initially, Luffy was unable to control his stretching, but was able to master it after ten years of training on Dawn Island, and further master it during the two years he spent training with Silvers Rayleigh on Rusukaina.
During the Wano Country Arc, it was revealed that it is actually a Mythical Zoan-type Devil Fruit, the Hito Hito no Mi, Model: Nika, which allows the user to become an incarnation of Nika, an ever-playful Sun God known for liberating slaves and bringing smiles to people's faces. This grants Luffy's body a rubber physiology and allows him to fight however he pleases, just as long as he can imagine it. According to the Five Elder St. Shepherd Ju Peter, because of the smiles Nika can put on the faces of others, he is known as the "Warrior of Liberation", and that "there is no power more ridiculous in all the world".
Luffy is one of the few people in the world capable of using all three types of Haki, and so far, he is one of only two people in the series to be confirmed to be capable of utilizing the advanced application of all three types, the other being Kaidou. Most notably, Silvers Rayleigh, the former first mate and right-hand man of Gol D. Roger, instructed him during the two-year timeskip, and stated he has a noticeable talent for Haki, having mastered the basic applications of all three forms of Haki in only a year and a half.
Even before finding out what Haki was, Blackbeard noted that his Haki had grown stronger by the time of the mass breakout in Impel Down compared to their first meeting on Jaya.
Through fighting against and training with powerful Haki users in the New World, in particular, those related to the Four Emperors, in addition to the Emperors themselves, Luffy strengthened his skill with each form of Haki to a much greater degree and learned how to use their advanced applications.
