Monkey D. Luffy is The Captain of the Straw Hat Pirates; your average seventeen/nineteen-year-old Shōnen Idiot Hero whose actions form the basis of One Piece as a whole. He's the son of Monkey D. Dragon, a revolutionary considered "The Worst Criminal In the World"; and the grandson of Monkey D. Garp, a humongously powerful Marine vice-admiral who had cornered the late Pirate King himself on several occasions. He seeks to find One Piece and become the new Pirate King; to accomplish this, he founded the Straw Hat Pirates and set out on the high seas at age 17 in search of the elusive treasure, beginning a series of increasingly odd and dangerous adventures. Physically speaking, Luffy is exceptionally strong, fast and tough, and fights barehanded. He ate the "Gum-Gum" Fruitnote  at the age of seven, giving him stretching powers that he has become quite a master of. Also, after training with Silvers Rayleigh, he has mastered the 3 types of Haki (literally "Ambition", it functions like chi).

His dream of becoming the Pirate King comes from an incident in his youth involving mountain bandits and a sea serpent that resulted in his idol Shanks losing his left arm. Before leaving Luffy's village the very next day, Shanks gave him his straw hat, telling him to give it back when he's become a great pirate.

Luffy is quite notorious for battling powerful individuals and organisations wherever he goes, and regularly poses a threat to the balance of the world by challenging the Seven Warlords of the Sea, the World Government and the Emperors and so far has managed to either win completely or escape by a hair's breadth. Through word of his various exploits and victories spreading around, he's already become one of the most infamous and feared pirate captains in the world after the Timeskip. He's also counted as a member of "The Worst Generation", a group of 10 other rookie pirates plus Blackbeard who are all considered to be major figures in shaping the New Age of Piracy following the Paramount War.

On the other side, Luffy is so amicable and charismatic that he has loyal allies throughout the world, including several countries such as Alabasta, Drum Island, Dressrosa, and Fishman Island, or miscellaneous organisations like the Galley-la Company and other similarly benevolent pirates like the Red Hair Pirates.

Following the events of the Whole Cake Island Arc, Luffy's successful 'raid' against the Emperor Big Mom note , the complete destruction of her castle, and his defeat of her two top Commanders was made public knowledge by the journalist "Big News" Morgans. Furthermore, the formation of the Straw Hat Grand Fleet and the addition of a former Warlord to his main crew (Jinbe) was also revealed to the masses. For this, Luffy is now considered the Fifth Emperor of the Sea in certain circles and has become unambiguously recognized as one of the most powerful individuals in the world with an enormous bounty to match.

He has a bounty of 1,500,000,000 Berries.note  He currently holds several records for his bounties.note

    #-E 
  • #1 Dime: His trademark straw hat is a gift from his idol Shanks, and he treasures it to the point where if he gives it to someone else, it's really saying something. Likewise, if someone ever dares damage it, ass will be kicked in great quantities. When he got struck hard with Heroic B.S.O.D. during Marineford arc, he got so distraught that he didn't realize that his hat fell down; Shanks found it and then told Buggy to give it back to Luffy. Its importance may have been elevated recently, given that a flashback revealed that the hat may have belonged to Gold Roger himself.
  • Achey Scars: Shortly before the Timeskip, Luffy got a scar on his chest from admiral Akainu. First time Akainu is mentioned after the timeskip, Luffy takes a hand to his scar and squints one of his eyes as if in pain, implying that this trope also has affected him.
  • Achievements in Ignorance: How he became the "Fifth Emperor" and received his ridiculously high bounty. The Straw Hats only entered Big Mom's territory to get Sanji back, and only involved themselves in Bege's assassination plot to save Sanji's family. The subsequent "raid" on Totto Land was really just collateral damage from having the Big Mom Pirates chase after them all over the archipelago, and Luffy's fights (and ultimately defeats) with Cracker and Katakuri were to get to Sanji and protect the crew, respectively. They were so focused on rescuing Sanji and escaping Totto Land, that none of them (except possibly Jimbei) realized the sheer magnitude of their actions and what the consequences would be.
  • Acquired Poison Immunity: Because of his fight with Magellan and subsequent healing by Ivankov in Impel Down, his body is highly resistant against poison.
    • However, he's not completely immune to poisons. A strong enough poison (as in one that would cause instant death in a normal person), or excessive amounts (like enough to kill a giant) is still capable of making him extremely ill.
  • Ain't Too Proud to Beg: Vivi teaches Luffy that violence isn’t always the right answer during Drum Island arc. He shows he learned his lesson when he begs help for Sanji in Fishman Island. Pose of Supplication is also seen in Impel Down, where Luffy shows his gratitude to an unconscious Bon Clay.
  • The Alleged Boss:
    • Luffy's the captain of the Straw Hats but usually doesn't act like it. Particularly towards the beginning of the show, he tended to follow orders more than give them, prompting several characters to point out that Nami acted more like the captain than the actual captain.
    • In general, Luffy has a very laissez-faire approach to captaining. Everybody on the crew does whatever they want most of the time, and later follow him when he takes action, due to him having earned their admiration and loyalty. Small requests of his can sometimes be ignored, and members of the crew (Especially but not exclusively Nami) even physically abuse him sometimes. That said, when it comes to the big decisions, he has the final word.
    • Since the timeskip, Luffy has been more proactive in giving orders and deciding the crew's next actions. This due in no small part because now he can choose where to go now that Nami's log pose points to three islands instead of the next one, and moreso because his goal is to defeat all of the Emperors while in "Paradise", it was to cross it. Thus, his interactions involve alliance proposals or enemy faction encounter instead of the usual making-friend ones.
  • All for Nothing: Impel Down and Marineford I make up an entire All For Nothing arc. Luffy breaks into Impel Down to rescue his brother Ace upon learning he had been captured and sentenced to death. He fights his way down to the bottom level, surviving only due to luck and Heroic Willpower, only to find that Ace had already been removed for execution. Luffy then starts a Prison Riot to escape, letting hundreds of the world's worst convicts out in the process, and travels to the giant Pirates vs. Marines battle taking forth. Fighting past thousands of soldiers, including the Marines' top fighters, the Admirals, Luffy manages to free Ace from his Power Limiter handcuffs, and they begin to leave. Until Ace turns around in response to one of the Admiral's taunts, gets into a fight, loses, and dies to protect Luffy. If Luffy's reaction of going into a Heroic B.S.O.D. isn't sad enough, the realization that the past 51 chapters were all for naught makes it so much worse.
  • All-Loving Hero: Downplayed. Luffy will only go to the ends of the earth to help the people he "likes"; or, in other words, people who catch his attention for some reason or another. Of course, being The Hero, it just so happens that he "likes" most of the people he encounters (generally, anybody that's not trying to kill him and quite a few that have). But if you're someone he doesn't like, then your best bet is to run in the other direction as fast as possible. Specifically, Luffy only seems interested in helping those who are willing to help themselves. People who sit on the sidelines and hope for things to get better don't interest him, but those who will put themselves in danger to fight for their beliefs earn his respect. He even patently refuses to help Momonosuke save Wano Country until Momo shows a will to fight, caring more about the willingness to act than being begged for help. Still, as said above, he does not like people who hurt his friends, and given his tendency to make friends quickly, there's a good chance that any bad guy Luffy crosses paths with is about to get his ass whooped.
  • All Your Powers Combined: Luffy's Fourth Gear is a masterwork combination of his Devil Fruit powers and Haki. In appearance, it resembles Nightmare Luffy. In combat, it combines the principles of Bellamy's Spring powers (with his spring-loaded punches), and shows signs of the Six Forms' Geppou, not to mention Soru. The other variants of Gear Fourth tend to combine the above spring powers with either Gear Third (Tankman, which makes him nigh immovable but super durable and capable of hitting back with immense power) or Gear Second (Snakeman, which trades some defense for a vast increase in speed).
  • Almighty Janitor:
    • Before the Enies Lobby arc, he was regularly defeating people who should ostensibly have been way stronger than him on paper- yet he would never publicly get credit for it. By the midpoint of the series however, this began to be generally Subverted as he came to be famed across the world for his heritage and exploits as a pirate captain. Still played somewhat straight as he advances in his captaining career though; in particular, even though Supernovas are still thought to be far too inexperienced to challenge a Yonko's crew and have any hope of success, Luffy has proven himself powerful enough to one-shot an Emperor's dragon (albeit it with considerable effort).
    • Fully subverted after the Whole Cake Island arc. Luffy is now considered the "fifth" Emperor for "defeating" Big Mom, recruiting the Germa 66, Capone, and the Sun Pirates to his crew, and orchestrating a failed assassination attempt on Big Mom's life. All of which is technically true.
  • Always Save the Girl:
    • He puts his friends before everything else. In fact, prior to the Time Skip, Luffy's bounty tended to rise whenever there was a crisis involving the women of the crew. He gained his initial bounty when he beat Arlong and liberated Nami from his control, had it rise when he defeated Crocodile and helped save Vivi's country, and had another rise after his rescue of Robin at Enies Lobby. Downplayed in his third rise - the crew's encounter with Camie the mermaid is, indirectly, what caused the Straw Hats to scatter around the world and for Luffy to get the news about Ace's execution, but Luffy's motivation after that isn't for Camie. Instead, his actions over the course of that one week are to save Ace, and while the rescue isn't successful, Luffy ended up with another bounty increase – something remarkable, as three hundred million is largely considered the cap for a rookie pirate such as Luffy. Played straight in his fourth rise, a result of beating Doflamingo, with his primary motivation being to save Rebecca, even though the original plan was to just destroy the SMILE factory and let Kaido's rage do the rest.
    • It's also how he became the "Fifth Emperor" — Luffy and co. entered Big Mom's territory to get Sanji back. That being said, the mission was supposed to be undercover and undetected; they ended up getting caught, and a series of incidents and other circumstances (such as Sanji's wedding being a sham to assassinate him and his biological family) caused it to escalate to an assassination attempt on Big Mom and then a full-scale conflict that engulfed the entire archipelago. The crew was so focused on getting Sanji and escaping Totto Land alive that none of them realized the actual magnitude of their actions and what it would mean to the rest of the world.
  • Angst Coma: Granted, there's a large physical component of exhaustion to it as well, but it's Ace's death that sends him into white-eye gape-mouth land. It's actually so bad that Luffy doesn't even notice he's lost his prized straw hat, after it falls off him while Jimbei is rushing him to safety. This actually lasts two whole weeks for him, and when he wakes up, he flips out.
  • Angrish: After losing Ace and waking up from his Angst Coma, Luffy screams in agony and rage over what happened to his brother.
  • Animal Motifs: A Monkey, duh. Although a video game once had his motif as a lion, which is also a good fit, if you think about it. Lazy as hell, eats huge quantities of meat, courageous, and he will slaughter you if you mess with someone from his group.
  • Anti-Hero:
    • At the beginning of the series, he was a criminal in name only. He was sometimes a bit rude, and beat up "good guys" who really deserved it, but that was all.
    • Luffy has admitted that he doesn't want to be a hero. He'll help people if he deems that he "likes them", would rather die than leave a comrade behind, and doesn't do typical pirate things like rape and pillage, but he doesn't necessarily care what people think of him, and if the situation calls for it, he fights dirty and uses his enemies as human shields or human weapons (on one occasion) and destroys public property freely in his many battles and uses trees and buildings as weapons.
    • However, he does admire heroes enormously. His reasons for not wanting to be one is among the lines of him viewing heroes as completely selfless. In which case, his refusal stems from the expectations he, as a hero, would have to do that would bother him, i.e. sharing meat. He immediately agreed to be one after Jimbei promised he would get his meat rather than having to divide among the people. Seriously, It Makes Sense in Context.
    • During One Piece Film: Z, all the Straw Hats are determined to stop Z from blowing up the Grand Line (and everything and everyone on it) with his bombs. Except Luffy, who just wants his hat back.
  • The Apprentice: Part of his role in the Time Skip was being a student of Silvers Rayleigh.
  • Arch-Enemy: He made a lot of intimidating enemies throughout the entire series. The two that stand out from the rest have one thing in common: They both played huge parts in Ace's death.
  • Arms and Armor Theme Naming: He names most of his attacks after firearms and other weapons: Axe, Sickle, Scythe, Pistol, Bazooka, Cannon, Rifle, Gatling... Mixes with Animal Theme Naming for Fourth Gear attacks.
  • Artifact Alias: Rebecca and most of the populace in Dressrosa refer to him as "Lucy" long after they learn his real identity, out of sheer habit.
  • Asexuality: One of the closest examples for the trope that Shonen manga is probably ever going to get. Word of God mentions that Luffy is more interested in adventure than women, and that there will be no real romance in One Piece. See Chaste Hero below.
  • Awesomeness by Analysis: He observed the CP9 members using Soru, and he soon began using an even faster and superior version of the move while in Second Gear.
  • Aww, Look! They Really Do Love Each Other: For all his fear of him, when it comes down to it, Luffy truly does love his grandfather. When Garp stood in his path to Ace during the Paramount War, Luffy showed extreme reluctance at attacking him, all but begging him to get out of the way. It was only when Garp told him that he had no other choice that Luffy went through with it.
  • Badass Adorable: In just a few short years he's gone from an unknown with barely a rowboat to his name to one of the most infamous pirates in the world, with one of the highest active bounties. He is also a cute and handsome young man. He gets really adorable in his chibi-form after using Third Gear.
  • Badass Boast:
    • "I'M GONNA BE KING OF THE PIRATES!!!" It may not sound like much to our ears, but this statement is considered utterly shocking in-universe, as many mere mortals are scared to challenge the world like this. Furthermore, Luffy makes this boast to anyone, no matter who they might be or how strong they are, including Whitebeard.
    • In the Alabasta arc: "I am the man who will surpass you [Crocodile]!" Considering he said that to one of The Seven Warlords of the Sea, right after he rebuffed the above statement, that's really something.
    • And in the Thriller Bark arc: "Tell that idiot Moria, that if he lays a hand on my crew, I'll blast this island till there's nothing left!" Important to note that then Moria was also a Warlord, one with a higher bounty than him.
  • Badass Family: Just the latest in the Monkey line to cause headaches for the World Government.
  • Badass Longcoat: Wears one in One Piece Film: Strong World.
  • Badass on Paper:
    • If you were to put his relative strength level and improbable feats on paper, Luffy is a very dangerous pirate. However, paper doesn't account for his kind, cheerful behavior, or the fact that he's an idiot. This frequently crops up after the Time Skip, where people hear various rumors about Luffy (including that he's an eight-meter tall giant) and have a hard time connecting such an infamous pirate with... well, Luffy.
    • Another variation happens courtesy of the journalist "Big News" Morgans and his newspaper company. Reading Morgans' news report on Luffy's conflict with Big Mom, you'd think that Luffy was a Chessmaster and Person of Mass Destruction who orchestrated a full scale invasion and assassination attempt on Big Mom's territory, beat up her commanders, destroyed her country, and left alive. While a lot of that is technically true, the reality of the situation is that Luffy was trying to sneak in and leave undetected, got caught, suffered through some grueling battles for it, and nearly died several times while just barely escaping Big Mom in the end. He also had nothing to do with planning the assassination (though he and his crew are the only reasons it got as far as it did); that was all Bege.
  • Bad Liar: The only way his lies could be more blatant would be if a neon sign appeared on top of his head and flashed "I AM LYING" every time he lied.
  • Balloon Belly:
    • Comes with being a Big Eater and his elastic nature. Actually uses it in combat to great effect. After the Time Skip, he has learned to more accurately return the projectiles upgrading his belly into an Attack Reflector.
    • Uses it to even better effect with his Gear Fourth forms, where his permanent and seemingly comical balloon belly is actually a very important part of the transformations; even the mightiest blows simply bounce off him harmlessly if somebody tries attacking his body, and he can use it to launch his enemies with incredible force.
  • The Beastmaster: He becomes this after the timeskip, being able to tame and befriend huge and/or dangerous animals in a flash thanks to his Haki.
  • Benevolent Boss:
    • Luffy is a kind and loving captain to his crew, and doesn't control through fear, but genuinely loves them all.
    • Deconstructed in the Post-Enies Lobby arc. When Sanji informs the others that Usopp plans to return to the Straw Hat crew, Luffy, Nami, and Chopper are ecstatic and plan to go get Usopp and have him rejoin, but Zoro stops them. He gruffly, but correctly points out that it didn't matter who was right or wrong during Luffy and Usopp's argument/fight, but they both fought for their own belief of what was right and Usopp willingly left them. And, whether or not he agreed with Luffy, Usopp disrespected Luffy for not respecting his ruling on what to do with the Going Merry. And it doesn't matter how much of an Idiot Hero Luffy is; he's still the captain and whatever he says goes. If Luffy decides to just welcome Usopp back without getting an apology for what he did, it would be a captain letting a crew member walk over him instead of demanding respect.
  • Berserk Button:
    • Get between him and his food, and he will be angry.
    • Touch his hat without permission and he will pound you. Of course, if you are Nami, then he'll willingly hand it to you.
    • He may not act like it all the time, but for him, piracy is Serious Business. He doesn't take kindly to those who flaunt the jolly roger. Wapol learned that the hard way.
    • Tell Luffy you're going to become the Pirate King before he does while showing yourself to be an arrogant jerkass and his response is usually a finishing move. note 
    • Trampling people's dreams tends to tick him off.
    • Do not' be a massive dick to your underlings or people who should be your comrades if not friends and definitely don't try to kill them around Luffy. Even if your bounty is over 860,000,000, he will smash you to the ground.
  • Beware the Nice Ones: He's nice and kind-hearted, but you reeeeally don't want to make him angry. Seriously.
  • Beware the Silly Ones: Luffy is usually a simple-minded goofball. Just be careful not to get him genuinely angry.
  • Big Brother Instinct: Inverted. Luffy's the younger brother, but throughout the Marineford arc, he does everything he can to rescue older brother, Ace. This includes breaking in/out of Impel Down, trading years on his lifespan, teaming up with Crocodile, and punching his grandfather.
  • Big Brother Worship:
    • Downplayed. While Luffy clearly idolized his older adopted brother Ace when they were younger, they did have a bit of a sibling rivalry and not once was Luffy ever blind to Ace's faults. Nonetheless, it can be argued that Ace was the most important person in Luffy's life, protecting him and practically raising him to be the happy and carefree person he is today. Which is why Luffy was absolutely devastated when Ace died to protect him. One of the only reasons why Luffy never crossed the Despair Event Horizon after Ace's death is the realization that Ace died so he could live and would've wanted him to move on with his life.
    • It has also been shown that he had/has a similar relationship his other brother Sabo who has since been shown alive despite having been shot down by a Celestial Dragon in his youth.
  • Big Damn Heroes: Pulls it off several times:
    • During the Marineford arc, he manages to pull this trope off as he and the rest of the Impel Down escapees crash down from the sky, ship and all!
    • During the Fishman Island arc, just as Hody is about to take King Neptune's head, Shirahoshi screams for Luffy to help her father. Out comes Luffy at lightning-fast speed, who kicks Hody away to everyone present's shock.
    • During the Dressrosa arc, Luffy is still recovering from using Gear Fourth as Doflamingo comes dangerously close to making Rebecca cut her aunt down. He recovers and manages to stop Rebecca's blade with his Haki-imbued head just before the impact, partially thanks to Law's help. For extra badass points, the citizens were chanting his name and counting the seconds to his recovery.
  • Big Eater: The elastic stomach probably helps. At multiple points, he eats until his entire body is horribly distended. He can then digest it in about five seconds. Notably this is a major advantage when it comes to fighting the Big Mom Pirates as many of their Devil Fruits revolve around food themed abilities. Not only does this let him eat some of their moves, it lets him eat quickly enough to counter Gear Fourth's time limit weakness and keep fighting in that state far longer than he otherwise could.
  • Blood Brothers: With Ace and Sabo. None of them were related of course, but they were very close and made a ceremony of drinking sake and became brothers. Luffy was heartbroken by both their deaths, so no words can express the joy on his face when he learns that he still has one brother left in the world.
  • Blood Knight: Though not to the extent of Zoro (who can border on Nominal Hero at times), Luffy loves a good fight – and it doesn't help that it's one of the few things in this world he's good at, to the point of being considered a genius. Though he doesn't like pointless fights with weaklings, as shown with Bellamy.
  • Book Dumb:
    • Very much so when it comes to science and medicine — he once tried to heal a wounded Zoro by pouring booze on his face because "Zoro likes sake, so it'll make him better". However, he's a genius in combat, social skills, and politics, beating "wittier" enemies like Eneru.
    • In a filler arc, the Rainbow Mist Saga, the entire crew minus Robin were all utterly shocked that Luffy was interested in a book that she was reading, even though he was utterly bored out of his mind at the time.
    • One of the TV specials implies that he can't even read, much like Zoro.
  • Boring, but Practical: Luffy's primary combat strategy with Cracker is this, and gets lampshaded by Cracker himself. Since Cracker's "Armor" is simply biscuits created by Cracker's D.F. powers, all Luffy needs to do is eat and run until Cracker runs out of stamina.
  • Born Lucky: He has been described as having the Devil's Luck. While the lightning bolt that saved him on the execution platform may have been Dragon's doing, he's survived a number of encounters due only to extreme good fortune.
    • At one point, Basil Hawkins actually gauges Luffy's luck with his tarot cards. He attempts to create deadly scenarios that Luffy couldn't possibly survive, but no matter what he tries, Luffy's chance of survival never drops to 0%. Combine this with Luffy's determinator mentality and brilliant luck...
    • This doesn't just apply to surviving certain death either. Even taking into account his Magnetic Hero qualities Luffy has made some very helpful allies ranging from former members of the incredibly powerful Shichibukai to current members of the Revolutionary Army and fellow Supernovas are on friendly terms with him. He even has someone that is all but said to be the canonical World's Most Beautiful Woman in love with him (though, funnily enough, his Asexuality means that this goes completely wasted on him).
  • Born Winner: Much like his adopted brother, Luffy's heritage meant he had a lot of potential – the only difference is that his took a little longer to show. As a trade-off, Luffy was also completely unaware of his heritage when he was younger (unlike Ace) and was therefore more emotionally stable.
  • Break the Cutie: Unlike all his crewmembers, who have a traumatic past that defines their personality, Luffy’s breaking moment happened in the present storyline. Afterwards he Took a Level in Badass and became even more determined to protect his loved ones.
  • Bring It: With the dub version, this is what went down after the flag was burnt:
    Spandam: YOU'RE ALL GOING TO DIE! YOU MORONS CAN'T CHALLENGE THE ENTIRE WORLD AND EXPECT TO WIN!
    Luffy: OH, YEAH?!? BRING IT OOOOOOOOOON!!!
  • Building Swing: He can uses his rubber arms to swing from structures and climb buildings whenever he needs to. Unlike Robin though, who can also do this, Luffy tends to swing around recklessly and at high speeds.
  • Bully Hunter: In spite of his adamant claims to not be a hero, Luffy does NOT gracefully tolerate over-entitled assholes who use their positions and power to flagrantly bully those weaker than they are; he has a particularly sore spot towards Bad Bosses who mistreat loyal employees who they should be taking care of. Doing/being either of the above in front of him is a one way ticket to being pounded into the pavement. Note that this attitude of Luffy's is contagious; associate with him long enough and you will also catch his intolerance towards bullies (as shown with the originally cynical and unfeeling Zoro), even if you were once (working for) a bully yourself.
  • Bullying a Dragon: Comes hand-in-hand with his Leeroy Jenkins trait, he has a habit of picking fights with opponents way above his level. While many of these actually become a Crowning Moment of Awesome, a few went badly for him, such as picking a fight with Magellan and Big Mom and her family.
  • Bunny-Ears Lawyer: Luffy is an absolute idiot, having No Sense of Direction, constantly eating so much and then falling asleep right afterward and goes right for danger for no other reason than "FUN FUN FUN!". None of his crew mates deny that he's an idiot. None of his crew mates also deny that he deserves to be their captain, both as a fighter and as a leader.
  • But for Me, It Was Tuesday: Rare good-guy example. He repeatedly annoys people (including recurring villains) by forgetting their names, signature moves or even that he's met them at all.
  • Butt-Monkey: Constantly a victim of (comical) abuse from his crew mates due to his stupidity, and he frequently ends up in strange situations that keep him from fighting.
  • Cannot Keep a Secret: Most notably during the Impel Down arc. He casually tells Ivankov and everybody standing around in earshot that his father is Dragon the Revolutionary. After escaping, he does it again by telling everybody that Ace is Gold Roger's son. Both times he remembers that he wasn't supposed to tell that to anybody else. It's implied that he gets this trait from his grandfather Garp who does the exact same thing after telling the Straw Hats (and Marines) that Luffy's father is Dragon the most wanted man in the world.
  • Catch-Phrase:
    • "I'm gonna be Pirate King!"
    • "MEAT!"
  • Can Not Tell A Lie: He's an outrageously Bad Liar, to the point that almost everyone sees through his attempts at lying right away (The only one who does fall for most of them is Chopper).
  • Character Development: Prior to the timeskip, he was your typical Shonen Hero. Kind as a saint, strong as hell, dumb as rocks. After the timeskip, however, he is notably leaps and bounds more composed than he was prior to it, now preferring to state what he'll be doing and go through with it rather than scream and shout (except when he's really riled up) and, more importantly, he is actually a respectable and capable leader, listening to his crewmates but never letting himself be questioned (save for in comedic moments) as Captain. All in all, he's gone from Shonen Hero, to Shonen... well, pirate captain. And, while he's still definitely Luffy as before, Marineford and Rayleigh have beaten some serious growth into him. As if to enforce this, when Big Mom's ship arrives to capture Caesar, Luffy immediately inquires whether or not Big Mom is on the ship in order to make his next decision of whether or not allowing the Straw Hats at sea to fight.
  • Character Tics:
    • Luffy has a tendency to suck his lips in and turn his head to the side when an attack or technique fails to affect him, such as Enel's various electrical attacks or Boa Hancock's Mero Mero no Mi.
    • After defeating an enemy, Luffy will smile about his victory.
  • Charles Atlas Superpower: Thanks to the Training from Hell his grandpa put him through, he's strong enough to destroy steel with his bare hands, knock out large sea monsters, and push apart two buildings he was stuck between. And that's not even using his Devil Fruit ability.
  • Chaste Hero: Though he knows what romantic relationships are, he just isn't interested... this actually becomes a plot point when he ends up on the island of the Kuja. In SBS 88, Oda says that Luffy can tell whether or not a female face is pretty, but it is just a classification for him.
  • Chick Magnet: He's one of the only characters in the series to actively have women falling for him. His reactions range from being suitably creeped-out, complete obliviousness or platonically appreciative.
    • Alvida (post-Gonk phase) only has eyes for him.
    • Almost the entirety of Amazon Lily are head over heels for him, especially Boa Hancock who acts like a lovestruck, teenage girl when around him.
    • Now he's got the Minkwoman Wanda repeatedly licking his face while commenting that "hairless bodies are quite beautiful". He's not amused.
    • Sanji's sister Reiju seems to rather... enjoy getting to give him a Kiss of Life while he suffers from poison.
  • Clark Kent Outfit: Before the Timeskip, the seemingly scrawny Luffy typically wore a closed vest that hid his surprisingly well built physique. Furthermore, like Zoro, his arm muscles are shown to grow much larger than you'd think when he flexes.
  • Cloud Cuckoo Lander: When he tries to be at his sharpest outside of battle, he can only pull this off. Most of the time he's something between The Ditz and The Fool.
  • Combat Clairvoyance: After the timeskip, Luffy has mastered Observation Haki, a power that allows one to anticipate an opponent's next move. He has learned it to such an extent that he can sense where his enemies are.
  • Combat Pragmatist: Luffy is not adverse to hitting below the belt or taking Human Shields when necessary... or if it's amusing.
    • A notable subversion is his fight with Admiral Fujitora. Luffy absolutely refused to take advantage of the man's blindness. He didn't pull his punches, but he did shout out his attacks and where he was aiming to give Fujitora a chance to react.
  • Coming-of-Age Story: Luffy's journey is to become the King of the Pirates and leaving his adoptive family behind.
  • Compelling Voice: A manifestation of his awesomeness. It used to be involuntary and limited to really desperate shouting. He doesn't need to actually speak to use it anymore.
  • Confusion Fu: Luffy, unlike the other characters, seems to fight freestyle. Being rubber makes this befitting. It even turned into an advantage against Eneru, who can read minds. Luffy simply ricocheted his moves off a wall, making it impossible for anyone, including himself, to predict their path.
  • Contagious Heroism: Luffy is hardly a hero (and doesn't want to be one), but he has a massive problem with powerful people abusing their power and often demonstrates it with his fists. Thanks to his charismatic and caring nature, this attitude quickly takes hold on most of his crew mates, even on the stoic and previously uncaring swordsman Zoro and the emotionally reserved Robin, who betrayed every other organization she was a part of before she met Luffy.
  • Crippling Overspecialisation: He's very useless at anything but having fun, eating, sleeping, being happy and amiable, and beating people up. He gathers his crew around him over the course of his adventure because he knows he can't go on without their help. He even acknowledges this during the Arlong arc when Arlong sneers down at him for keeping friends. He retaliates by picking up a pair of swords and waving them wildly in Arlong's face, to no avail. Arlong sneers at him some more, for now trying something he knew he couldn't pull off, and Luffy comes out with this Tearjerker of a line, while the camera pans over each crew member that fulfills each job:
    I know! Of course I can't use swords, you idiot! I can't navigate! I can't cook! I can't even tell lies! This is why I need my friends if I want to survive!
  • Crouching Moron, Hidden Badass: Often both a badass and a moron at the same time. He actually tries to weaponize his idiot nature in the Eneru fight, in order to defeat his mind-reading. It works, but he also becomes too stupid to remember to attack.
  • Cruel Mercy: According to Oda, the reason Luffy doesn't kill his enemies (with the exception of the Big Bad from the 6th movie) is because he feels that letting them live with their dreams destroyed is a worse punishment, which makes sense considering the series is about characters pursuing their dreams. Considering what they did to Ace, however, Blackbeard and Akainu might be exceptions.
  • Cuddle Bug: Luffy shows how much he loves his friends by hugging them, regardless of gender. This can get problematic when the girl in question is actually romantically interested in him; doubly so because he won't return romantic love.
  • Cursed with Awesome: Like all Devil Fruit users, he's gained incredible powers at the cost of never being able to swim and being branded a freak forever. Not that either of these facts bother him, though. And unlike other Devil Fruit users, this does not scare him away from water sports.
  • Curtains Match The Windows: Luffy has black hair and black eyes.
  • Dangerous Forbidden Technique: All his Gears carry significant drawbacks; Second Gear is Cast from Hit Points and Third Gear had the side effect of making him shrink and lose speed and mobility (though he's overcome those weaknesses). Fourth Gear has the biggest drawbacks yet, it has a Time Limit and when it's up, he's drained of his haki and exhausted to the point that he can't even move for ten minutes. Meaning, he must finish the fight while it lasts, or his enemy will make short work of him during his downtime. This is even more evident when you realize that none of his enemies have such downtime when using their Super Mode/Limit Break.
  • Dark and Troubled Past: Luffy was abandoned by his parents and abused by his grandfather in training (though both of these experiences were Played for Laughs), but was given a relatively stable upbringing with the mountain bandits of Goa and his adoptive brother, Ace. Still, he suffered a traumatic experience after eating his devil fruit where his idol, Shanks, lost an arm saving him from a Sea King. He and Ace then suffered an arguably even more traumatic experience during the fire that burned Grey Terminal, which eventually ended with the death of their other best friend and sworn brother, Sabo. Of course, Sabo turned out to have survived, but that's a moot point considering he didn't find out years later, long after the traumatic experience of losing Ace.
  • Death Glare: He always stares down enemies, and when pissed gives these. Two particularly intense faces occur, 1st was right before he defeated Lucci with his Jet Gatling. And the 2nd one was to Jimbei while he was having a truly epic Freak Out! on Amazon Lily. Later becomes one of his regular abilities thanks to Haki.
  • Defeating the Undefeatable:
    • Many of his opponents. Eneru is probably the best example, as he spent most of the Skypiea arc proving how strong he was. This becomes a plot point: A big part of the character development of Luffy comes from the realization that it's impossible for him to beat the most powerful Marines and pirates of the New World. Cue 2 years training with the Pirate King's first mate. Following that, Luffy resumes the trend, starting with bringing down Donquixote Doflamingo.
    • Charlotte Katakuri in particular is a notable case, as he was straight-up confirmed to be undefeated until Luffy beat him. He was so strong that his family refused to even consider the remotest possibility that he lost, and even when learning the truth after Luffy escapes the Mirror World, they either outright deny it or accuse Luffy of having used a dirty trick to win.
  • Delayed Reaction: Used a lot of times for comedic effect.
  • Despair Event Horizon: Ace's death drives him to despair. Fortunately, Jimbei helps him snap out of it.
  • Determinator:
    • Luffy powers through injuries that should have killed him several times over, often without outside assistance. In no particular order, he's been dehydrated to a dessicated husk, skewered, cut, drowned, blown up, bitten (a super strong shark bite, mind you), beaten to a bloody pulp, stabbed, crushed, covered in arrows (in one of the movies), frozen, burnt, shot by lasers, and poisoned to the point of melting, yet is still alive and kicking.
    • The poisoned part was almost a subversion, because it all but killed him. He was healed by Ivankov, but the technique used was explicitly reliant on the patient's will to live and Ivankov was especially shocked that Luffy recovered in a few hours, despite his initial estimate that it would take days for Luffy to recover, if he recovered at all.
    • A quantifiable example of his Determinator status was shown off at the end of the Thriller Bark arc, when Bartholomew Kuma pushed all of Luffy's pain out of him and into Zoro, and the damage it dealt to Zoro was... not pretty.
  • Deus Exit Machina: He's the strongest of the crew along with Zoro and Sanji, and the most likely to get lost, trapped or otherwise unable to initially participate in battle until the most powerful enemy remains.
  • Did You Just Flip Off Cthulhu?: Yes. Luffy is prone to this.
    • At Enies Lobby when Spandam is gloating about how the World Government is unstoppable, he orders Sogeking (Usopp, but he doesn't realize it) to burn their flag, effectively declaring war on the WG and all 170+ of its member nations.
    • After learning that Big Mom of the Four Emperors is going to destroy Fishman Island because they were unable to give her her monthly 10-ton delivery of candy (due to Hody destroying the candy factory and the Straw Hats eating the rest), Luffy does what no other pirate would dare do – he takes the Transponder Snail (i.e. a phone in the One Piece world) from Big Mom's subordinate and tells her he himself ate all 10 tons of her candy and that it's too dangerous to leave her in charge of the island, so when he gets to the New World he's going to kick her ass and claim Fishman Island as his OWN territory; Big Mom declares war on the Straw Hat Pirates.
  • The Ditz: In one of the data books, his intelligence score was a whopping 1/5.
  • Dodge the Bullet: Despite being Immune to Bullets, he has extremely sharp reflexes and can also dodge bullets with ease.
  • Does Not Like Spam: It's revealed while fighting Katakuri that Luffy hates mochi.
  • Dope Slap: Is the victim of this a lot due to his stupidity.
  • The Dreaded:
    • Due to his actions during the Paramount War, along with his actions while with his crew (such as Enies Lobby and Sabaody), Luffy's become so infamous that anyone who isn't as strong as one of the Seven Warlords of the Sea instantly fears him. For instance, at Corrida Colosseum, while incognito, he accidentally gives his real name and everyone immediately freaks out. They only stop once they see the sign on his back that says "Lucy", and start remembering rumors about him being an eight-meter tall giant.
    • As of the Reverie arc, he is one of the most feared pirates in the world, now considered on par with the Four Emperors. It's now a given.
  • Dumbass Has a Point: There have been moments where he surprises his crew by saying something that actually makes sense:
    • In the Alabasta Arc, Luffy refuse to follow Vivi to Koza's main base as he stated that Koza and his rebellion army would never believe her since this is coming from Luffy and his crew who are pirates and instead go after Crocodile at Rainbase instead. He also mentions that people will die no matter what Vivi does, a surprisingly realistic observation for him that the other crew members don't contest.
    • After dropping down from Skypiea, Luffy suggest the crew get a shipwright to fix the Going Merry (despite him suggesting a musician after the crew was surprised by his words).
    • In Water 7, upon learning the Going Merry was on her last legs, Luffy made the tough call to seek out a new ship. And during his argument with Usopp, Luffy made three valid points. First, during his verbal argument with Usopp, Luffy pointed out that the former isn't an actual shipwright and doesn't really know the Going Merry's condition unlike an official shipwright. Secondly, when he starts to roughly handle Usopp, Luffy mentions that he is the captain and his orders are to be followed and was about to say that Usopp should leave if he couldn't follow his orders, before being stopped by Sanji. Thirdly, when Usopp challenged Luffy to a one-on-one fight for ownership of the Merry, Luffy chose to go through with it, and when Nami asked why he isn't trying to stop it, Luffy pointed out that he knew Usopp was dead serious about it and wouldn't be convinced any other way. Despite her misgivings, she didn't argue with him anymore.
    • While infiltrating Big Mom's home island, Nami freaks out when a giant crocodile in human clothes speaks to them and walks away. Luffy points out they have seen weird things like that before, pointing to their present company Chopper and Carrot, a literal bunny-girl.
  • Dumb Is Good: While Luffy has low intelligence about things like mathematics and science, he is a very good and mostly pure man. He will go out of his way to help people if they were kind to him, and recognize when he is in a situation he needs help in.
  • Dumb Muscle: There is a reason that his head has a bounty of 1,500,000,000 beri; he's so powerful that almost everyone fears him, even experienced pirates who are grown men. Despite this, he's dumb as rocks, and incredibly naïve.
  • Dynamic Entry:
    • How did he get to Marineford? Well, it overlaps with Big Damn Heroes, 'cause he dropped a ship out of the sky! (It wasn't intentional, but that doesn't make it any less awesome)
    • Done again in the Fishman Island arc when he leaps out of a shark's mouth and kicks Hody Jones just as he's about to assassinate the king.
  • Easily Impressed: Despite living in a world where eating fruit can give magic powers and sea monsters bigger than the Titanic are aplenty, Luffy often gets wowed by the silliest things. Namely, Franky's goofy gadgets.
  • Elemental Punch: His unique rubber body allows him to do two types, fire and lightning. When the heat from Second Gear is combined with haki on his arm, it lights on fire. As for the lightning, he can absorb the lighting during a storm into his limbs (since rubber is an insulator) and attacks with it.
  • Enemy Mine: Seems to have a knack for pulling this off, even in the most unlikely of cases. Mihawk actually considers this his most dangerous ability.
  • Enhanced Punch: Luffy has many of this kind of move, but the most notable would be his Gum Gum Pistol, Bazooka and many variations of it, which are given additional range and force by his Rubber Man powers. Later, he learns to blow his limbs up to gigantic size for even more force.
  • Establishing Character Moment: Two primarily. The first is when he stabs his own face at just 7 years old in order to prove his manliness, and the second would be when he starts his adventure by punching out a giant monster, yelling out his ambition in triumph, and then laughing it off when he gets sucked into a whirlpool a few minutes later.
  • Everyone Calls Him "Barkeep": Luffy gets called "Straw Hat" by everyone he fights, with rare exceptions.
  • Everyone Has Standards:
    • Luffy's usually a nice guy who can befriend and forgive nearly anyone, up to and including former antagonists regardless of morality. However, he drew the line upon seeing Crocodile in Impel Down. He did end up releasing him, at his ally Ivankov's suggestion, but unlike all the other former enemies he meets in the arc, Luffy does not befriend or forgive him.
    • Luffy may be a big-time Combat Pragmatist, but even he draws the line at taking advantage of Admiral Fujitora's blindness, and calls out the targets of his own attacks to give the man a fair chance to react.
    • Luffy made it clear that he'd never forgive Bege for shooting Pekoms, even promising him that he'll punch him in the face (something Bege said he'd let him do), but when the assassination attempt failed and Big Mom begins attacking Bege's castle, therefore hurting him, Luffy feel compelled to help Bege get out of this alive as he knows Bege (intentional or not) was taking hits meant for the Straw Hats as well, completely forgetting his grudge towards him.
  • Experienced Protagonist: Has shades even though he underwent some training for two years, Luffy was already a skilled fighter from the start of the series — having trained for 10 years.
  • Expy: Of Son Goku from Dragon Ball, in a spiritual sense. Oda said he designed Luffy based on what 'manliness' meant to him as a child and he shares many of Goku's characteristics; such as being a Big Eater, Book Dumb, naive about the world, simple-minded, and being a Crouching Moron, Hidden Badass when it comes to fighting. Incidentally, Luffy met Goku in the Dragon Ball x One Piece - Cross Epoch crossover. He even got to ride on the Flying Nimbus.

    F-K 
  • Failure Hero: He gets hit with this status in the Sabaody, Impel Down, and Marineford story arcs. He is separated from his crew by Bartholomew Kuma, discovers that Ace is to be sentenced to death, is poisoned by Magellan during his rescue attempt on Ace in Impel Down, is forced to leave Bon Clay behind after escaping the prison, gets overpowered by the Marines, witnesses Ace's death at the hands of Akainu, and Jimbei and Law end up rescuing him.
  • Fatal Flaw: Luffy has three:
    • Wrath. Luffy's inability to control his volcanic-rage is precisely what led to Kuma attacking and dispersing his crew around the world, leaving him all alone in the world for two years.
    • Also selfishness. His selfishness isn't your typical it's-all-about-me-attitude, more about his selfish desires like having meat and good adventure, becoming the Pirate King, and protecting his friends. In the Sabaody arc, he didn't act on impulse but he seethed with Tranquil Fury. Luffy did what he felt he had to do, even though he knew it would have grave results. He apologized immediately after hitting Saint Charloss, but showed no regrets. Including the Sabaody incident, Luffy's selfishness is portrayed through the whole series, sometimes in comedic light, but it has always been there, and several characters have commented on it.
    • Honestly, it's his fearlessness more than anything that proves to be both his greatest asset and his greatest flaw. His utter lack of fear of anybody or anything has led to a lot of stupid decisions over the years, and although he sometimes sees it as a problem, he has yet to find any effective way to deal with it, and the one time he tried, Kuma scattered his crew across the world in such a way that it looked like they were outright atomized to him.
  • A Father to His Men: Luffy deeply cares for his crew and will go Papa Wolf on anyone who dares to hurt any of them.
  • Fearful Symmetry: Over the course of his journey, Luffy has occasionally ran into enemies that like to imitate his powers and abilities;
    • The first, Downplayed example of this was Oars, a demonic giant that was infused with Luffy's shadow by Gecko Moria's powers. Oars, possessing Luffy's personality and a few vague memories, was given the ability to stretch by Moria and used some of Luffy's techniques against him. At the time though, Luffy had become "Nightmare Luffy" and completely overwhelmed Oars.
    • Much later, this trope is played straight when Luffy encounters Charlotte Brulee, a Big Mom pirate with a Mirror Devil Fruit that allows her to transform into Luffy and match his every move blow for blow.
    • Charlotte Katakuri invokes a Downplayed version of the trope. The user of the Mochi-Mochi fruit, he can stretch and contort his body just like Luffy, but is superior in many ways; Luffy's body only takes on the properties of rubber while Katakuri can actually transform into mochi; Luffy's Gatling only creates the illusion of growing more arms, while Katakuri can actually grow more arms; Luffy's Elephant Gun is limited by how much air he can blow into his hand while Katakuri's Elephant Gun can be any size he wants. As such, Luffy has a hard time against him.
  • Fearless Fool: More often than not, he never realized how strong his opposition/problem in front of him would be, and he'd just punch it until it goes down. It works well for him most of the time because of his Determinator traits and having a very good luck.
  • Fighting the Lancer:
    • Played for Laughs in his fight with Zoro during the Alabasta Saga. After being treated to drugged food by a bunch of bounty hunters, Zoro the lancer beats the ever-loving crap out of them. Luffy wakes up, and thinks that Zoro just attacked the people who were nice to him and gave him food; a battle ensues.
    • Played for Drama in the Water Seven Arc in his fight with Usopp. With a growing conflict between the two, due to emotional problems Usopp started developing during the arc, and Luffy's decision regarding their ship (which Usopp was very fond of); the conflict grows into fight between them.
  • Fight Off the Kryptonite: Two notable occasions: In Alabasta, in Crocodile's Elaborate Underground Base which was flooded, he fought off Bananagators with Zoro and Sanji, as half his body was already underwater. Then in Fishman Island, most of his fight with Hody Jones had him at major disadvantage as he doing it underwater. It was still ridiculously one-sided even before the fight was taken to a bubble-coated giant ship where he could fight with some air.
  • Fire-Forged Friends: He tends to have this relationship with many of the people he encounters, whether it be with his crew members or one-arc allies. When he meets them, they tend to be extremely exasperated with his stupidity. By the end of the arc, they are able to see Luffy's more notable qualities.
  • Flash Step: When using Second Gear.
  • Foe-Tossing Charge: He tends to do this whenever enemy forces make the mistake of sending lowly mooks at him when he needs to get somewhere, usually sending hundreds or even thousands of them flying at a time. Notable cases include Enies Lobby, Marineford, and Totto Land.
  • The Fool: He's got a dream that he works towards, but he has no head for the myriad of politics and criminal conspiracies that infest his world, causing him to blunder into and overcome schemes in his earnest and largely innocent quest for adventure.
  • Foolish Sibling, Responsible Sibling: Definitely the former when compared to Ace as Luffy is the more reckless of the two.
  • Forgot I Couldn't Swim: This happens to a lot of DF users, of course, but it was kind of a Running Gag with Luffy. Probably the most hilarious incident was when Chopper and Brook valiantly leap into the sea to rescue him, completely forgetting that their Devil Fruits make them unable to swim.
  • Freak Out!: When he recovers from his Heroic B.S.O.D. and realizes Ace is truly dead. In the anime, he also freaks out when Kuma scatters his crew, and when Ace is killed. The latter example is particularly terrifying, to say the least.
  • Friends Are Chosen, Family Aren't: It's a running gag that Luffy hardly even knows about his family, let alone their infamous reputations, while he shows the utmost care for his friends.
  • Friend to All Living Things: At one point, he was able to befriend a Kraken.
  • Fun Personified: Seriously. On top of everything else, his powers are genuinely like something taken out from a Tex Avery cartoon.
  • Funny Afro: He dons one fighting against Foxy. It helps him win.
  • Fun Size: The after effect of his Third Gear technique causes him to shrink into a chibi version of himself. He overcomes this weakness after the timeskip.
  • Generation Xerox: He has been compared to Gold Roger by multiple people who've encountered him. Given his simple outlook on life and violence towards anyone who hurts his friends, he can also be seen as a Generation Xerox of Shanks. According to Ivankov, Luffy is very similar to his father.
  • Genius Ditz: Luffy is childish and naive, but his brilliance is found in fighting, first and foremost. He takes one of more lackluster Devil Fruits, one which his more talented brother told him would amount to nothing in combat, and turns it into one of the most dangerous abilities in the series. Luffy constantly figures out new applications of his Rubber Man powers in ingenious ways, showing he is able able to grasp the properties of rubber to the extent that he can learn how to set his arm on fire and create the Gears. He is also very perceptive and adaptive to his environment, being able to figure out Crocodile's weakness of the verge of death and creating a number of counterattacks to Enel's Mantra on the spot. Mihawk even commented that he was "unusually clear headed" during the Summit War, implying he's not as much of an airhead as he seems. He also learned all Rayleigh had to teach him about Haki in just one and a half years, excels at understanding people's emotions and motivations, and possesses a form of wisdom that allows him to see the simplest solution needed (such as knowing that interfering with the Alabasta army won't guarantee anything and what's needed to be done is defeating Crocodile.)
  • Get a Hold of Yourself, Man!: He punches Sanji in the face after he repeatedly tries to get him to leave Totto Land by lying about his desire to go back to the crew. Naturally, this finally gets to him to admit that he wants to come back to the crew.
  • Good Cannot Comprehend Evil: When Judge lists out every last reason he finds Sanji unworthy, including his lack of royal pride, the sway his emotions have, his foolish need to help others, his love of cooking like he was some lowly commoner and generally having compassion making him unfit as the Super Soldier he was intended to be, Luffy just doesn't understand why anyone'd see all that as bad, wondering why he was listing all of Sanji's good qualities all of a sudden. He simply can't get into the mindset of a man like Judge, prideful, royal and hateful of any sort of compassion, and doesn't really understand such a mindset can exist.
  • Good Old Fisticuffs: A straight example. He doesn't practice any martial arts, but he's such a creative and gifted fighter that he can take on martial artists and win with just his own free-form style.
  • Good Scars, Evil Scars:
    • Luffy has a small scar under his eye; the manga originally began with him cutting his face to prove himself to be a man, but this was cut out of the anime.
    • After the timeskip, Luffy has an X burn scar on his chest from Akainu's attack.
  • Go Out with a Smile: Just like anybody else with D. as their middle initial, he's prone to this trope. Notably, he smiled before Buggy almost cut his head off at Logue Town.
  • Gratuitous English: Most of his attacks have English names, particularly in Second Gear.
  • Greater Need Than Mine: It does not matter that he is badly hurt and freezing to death, or poisoned to the point of melting, his friends come first. He never even asks for himself to be helped, merely begs for whoever is there to aid his companions.
  • Hairstyle Inertia: Since his childhood, Luffy still sports the same messy, spiky head of hair.
  • Hat Damage: Though he takes good care of his signature straw hat, this can still happen. Woe be to the person that does it, though.
  • Heavy Sleeper: Seems to be a family trait.
  • The Hero: He is the main protagonist, after all. In terms of how much of a Hero he actually is, it's complicated, but generally speaking he finds himself doing what others would call "the right thing" anyway simply because of how he is.
  • Hero with Bad Publicity:
    • He quickly goes from being the hero of Dressrosa to being public enemy number one after they mistakenly think he's kidnapped princess Rebecca (he's actually taking her to see her father). Though it turns out to be a subversion, as the citizens of Dressrosa actually know full well where Luffy was taking Rebecca, and were chasing after him so that Fujitora wouldn't be able to destroy the ships the Straw Hats were using to escape, for fear of catching the civilians in the crossfire.
    • His general reputation to civilians worldwide is this, as they're under the impression he's a ruthless and wild pirate who terrorizes people for the fun of it. Now, he's not The Cape or the Ideal Hero or anything (and doesn't want to be), but nonetheless he happens to be a morally upright man who wouldn't go out of his way to harm civilians or even cause trouble for no reason. Luffy's entire conflict with the law, going back to the East Blue days, started simply because he calls himself a pirate.
  • Heroes Fight Barehanded: He is incapable of fighting with the use of weapons, but his barehanded fighting prowess is so much so that he has been labelled a fighting genius.
  • Heroic B.S.O.D.: Gets hit with this hard when Ace gets killed. After Ace's death, there is a look of despair on Luffy's face that has never been seen before.
  • Heroic R.R.O.D.:
    • His Second Gear pre-Time Skip shortens his lifespan with each use, and will eventually wear him out if overused. Third Gear also might count, although it only shrinks Luffy temporarily after each use, with no mentioned long-term effect. As well as that weakness he overcame after the Time Skip.
    • When Ivankov gave Luffy his "miracle treatment" to heal Luffy of Magellan's poison, it took an additional ten years off Luffy's lifespan. Add this to the Second Gear, and the regular damage Luffy takes, and Oda seems to be strongly implying that Luffy will die young.
    • Even his Fourth Gear has a major drawback: it has a time limit, and when it runs out, Luffy's haki is unusable for 10 minutes. It gets worse of he overtaxes the time limit, exhausting his body, his devil fruit power *and* his haki for 10 minutes. If his opponent is still going, he's left extremely vulnerable until he recovers. This can be countered by eating sufficient amounts of food to regain his strength, however.
  • Heroic Second Wind: Finally defeated Rob Lucci with one after being spurred on by Usopp.
  • Hilariously Abusive Childhood: Child abuse isn't funny... except when it involves throwing the child down a ravine, leaving him in the in the wilderness, and attaching enough helium balloons to him to make him float into the sky, all for the purposes of increasing his survival skills. Further adding to the hilarity is the fact that each of these scenarios has Luffy animated in the exact same pose with the exact same scream, with different backgrounds for each. After hearing about it, his crew immediately realizes just where Luffy got his strong will to live from.
  • Hollywood Healing: His battles only leave story relevant scars, like his trademark one under his eye he gave himself in Chapter 1, his X shaped scar he got from Akainu, or his missing tooth after taking a direct kick to the face from Sanji. Although in the case of that last one, this trope is played straight and Lampshaded several chapters later when he drinks some milk and his tooth grows back on the spot.
  • Honor Before Reason: During the Davy Back Fight, the Straw Hats lost the first round, forcing a member of their crew to join the Foxy Pirates. The Straw Hats win the second round and get to pick a Foxy Pirate to join them. Nami suggests picking Foxy himself, as he would be unable to participate in the third round duel and they would win by default, getting Chopper back without fighting. However, Luffy vetoes the plan, due to disliking Foxy too much to want him on the crew.
  • Horrible Judge of Character: Inverted. Despite his naivete and being easily fooled at times, Luffy seems to have a good judge of character given the people he befriends will almost always become loyal to him.
  • Hot-Blooded: In fine Shonen fashion. He's a more tranquil version, however, as he only really gets hot-blooded well into a battle or into a meal.
  • How Do I Shot Web?: As a child who had recently eaten the Gum-Gum Fruit, Luffy was rather unskilled with his stretching powers – especially when compared to his mastery at the start of his journey, years later. His signature Gum-Gum Pistol? His first attempt bounced off the ground and back into his own face.
  • Hulking Out: His latest Super Mode turned him into a Top-Heavy Guy.
  • Humble Hero: One of Luffy's dominant traits is his humble nature: he does not brag about the powerful foes he's defeated in the past, though he's not above about claiming that no one has ever beaten him in the past (which is not true, having been defeated many times by Ace and Sabo as a child, twice by Smoker (though non-fatal), twice by Crocodile before defeating him, once by Aokiji, once by Rob Lucci before defeating him, once by Gekko Moriah before defeating him, once by Bartholomew Kuma, once by Magellan and once by Kizaru, all in the past). He remains humble despite having done outrageous acts like defeating Shichibukai-level pirates and issuing the order to burn down the World Government Flag back at Enies Lobby. When Franky pointed out the latter, Luffy only replied that it was nothing to get worked up over (hinting that he only gave the order on a mere whim), for he and his crew were only there to take back a crew member that was taken from them. When Sengoku tried to cover up Gekko Moriah's defeat by ordering Bartholomew Kuma to kill the Straw Hat Crew, Vice Admiral Garp told him this, practically lampshading the trope:
    "Ah, do not worry yourself Sengoku! Luffy is not the sort of guy who'd go around boasting about taking out Moriah anyway!".
    • It's also this trait that immediately tips Sentomaru off that Demaro Black was an obvious imposter when he plays up his bloodline and acheivements.
  • Iconic Outfit:
    • The straw hat, in universe, as seen in the "From the decks of the world" cover story and at the end of the Fishman Island arc. The new shipment to the island will include straw hats. Why? Because the kids want to play heroes!
    • His first outfit, the red vest/blue shorts with sandals combo as well as his first Time skip outfit.
  • Identical Grandson: Garp looked identical to Luffy when he was a kid. He even had his scar at a young age. Even now you can see the resemblance, as Garp looks like a much older and brawnier Luffy.
    • SBS volume 89 presented a few glimpses at what Luffy could look like at age 40 and 60 and he himself ends up the spitting image of his grandfather "in a future where things go well."
  • Idiot Hero: Luffy is quite smart for a Shonen Hero, and not just in combat; he has shown an understanding of basic physics, social skills, survival skills, and politics. The 'Idiot' part comes from his simple outlook on life; while he understands that the current of Reverse Mountain has a scientific explanation, he prefers to just call it a "Mystery Mountain" because it's easier and more fun. That sort of description extends to several other subjects.
  • I Gave My Word: His word is the greatest thing he can give. He takes it seriously. How serious? He promised Robin he'd be her friend forever, so when she was taken from him, he went on a rampage resulting in the complete annihilation of a World Government island, thousands of unconscious mooks, and a staggering threefold (that would be two hundred MILLION) increase in his bounty. Do note that it's when he gave his word willingly that he will uphold it to the best of his power; when he's forced by circumstances to do it (such as when Hachi and his crew told him not to hurt any World Noble, and when Law told him to just capture Caesar), he can break his word if he gets too pissed off.
  • I Just Want to Have Friends: His reason for trying to hang out with Ace when they were kids, saying it's painful being alone.
  • I Just Want to Be Free: Luffy's reason for wanting to become the Pirate King is because he views the Pirate King as 'the one with the most freedom'.
  • I Let Gwen Stacy Die: Ace's death could be this for Luffy, as Akainu's magma punch was meant for him and the reason why he got handed over to the Marines is because Blackbeard was coming for Luffy, but Ace got to him first.
  • Immune to Bullets: They simply bounce off, though in the beginning of the series he claimed to still not like getting shot. Ostensibly he got used to it pretty quickly, considering the sheer number of times (often on purpose and/or easily avoidable) that he gets shot throughout the series.
  • I'm Not a Hero, I'm...: Invokes this with Jimbei. He says he likes heroes, but he knows he's a pirate.
  • Improbable Age: While this applies to the entire crew, Luffy's special in that he's already a legendary pirate and with a 500,000,000 berry bounty, considered one of the frontrunners for becoming Pirate King, and captain of one of the strongest crews on the Grand Line, all at the age of 19, while being a pirate (post-Time Skip) for only about three years, two of which were spent training alone. He's also one of the three youngest members of the crew, being the same age as Usopp and only two years older than Chopper. Taken Up to Eleven as of the Reverie Arc - at age 19, he's considered an Emperor of the Sea with a 1,500,000,000 berry bounty.
  • Improv Fu: This is Luffy's main fighting style, as he'll use anything available to him so he can win. This causes his opponents to underestimate him because, more often than not, it looks like him fooling around rather than fighting seriously.
  • Incorruptible Pure Pureness: No matter what happens, he will be always carefree and smiling non-stop. He never actually intended anything bad either because of his moral values or his naivete. Even Hancock's beauty has no effect on him.
  • Indy Ploy: Uses these quite a few times: notably during his fight with Eneru , during the assault on Enies Lobby , and later against Doflamingo
  • Innocently Insensitive: Towards everyone at some point, but the standout example would have to be the Mermaid Princess, Shirahoshi.
  • Instant Armor: One of the many people who can do this using Armament Haki, which turns any affected area of the body black and makes it much, much harder. It can also be used offensively (as the harder body makes for a harder hit) and Luffy is particularly skilled at this type of Haki, able to easily break through most of his opponents' defenses with it.
  • Ironic Hell: Inverted: Luffy ended up going to Amazon Lily, whose leader is the World's Most Beautiful Woman Boa Hancock. The natives end up worshipping him as much as they do their leader, and said leader Luffy ends up seeing naked. Twice. To top it all off, thanks to his kind nature, Hancock ends up falling in love with him. If it had been anyone else in this situation, they'd be praising the gods and living it up. However, not only is Luffy an Idiot Hero, he's also a Chaste Hero, making all of this an ironic heaven.
  • Irony: After all the times when he refused to give in until a person he was trying to recruit joined his crew, he finds himself being forced to take on 5640 followers who wish to serve him.
  • I Thought It Was Forbidden: Even though Second Gear reduces his overall lifespan, he tends to use it more and more often, to the point at which he resorts to it for most of his major fights since Enies Lobby. Before the time-skip Second Gear was activated by Luffy using his legs as a pump. After his training, he might've just grown so strong that he can't not use Second Gear when he flexes a muscle. Thankfully, though, he also only uses it in short bursts.
  • It Runs on Nonsensoleum: And also Rule of Funny and Artistic Licence: Biology; he completely regrows his missing tooth in chapter 858 after drinking some milk because... calcium! It's good for the bones! And teeth!
  • Jerk with a Heart of Gold: An obnoxious and buffoonish outlaw who is nonetheless friendly and for all his proclamations of selfishness, is one of the most outright heroic characters in the entire story.
  • Jerkass Façade: He pulls this sometimes to get his point across. Rarely lasts long.
  • Just Friends: Luffy, in his own pure-hearted way, does love Hancock back; the same way he would love and lay down his life for any of his precious friends. Hancock, although aware of this, personally wished it were something more (and still interprets his acts of kindness as reciprocating her feelings, even if he doesn't.)
  • Kiai: See the end of his fight with Rob Lucci.
  • Ki Attacks:
    • After the two year time-skip, he has completely mastered Haki and can use it to power up his already strong attacks and predict enemy attacks, just like Eneru and his priests.
    • When he uses Armament Haki, his body turns dark and shiny, as if his rubber body has gone through a form of vulcanization.
  • Kindhearted Simpleton: Luffy is very cheerful and kind to his friends, but not book smart. He tends to be spacy and fueled by his emotions. But when it comes to fighting, he is very good at understanding what is needed to win.
  • Know When to Fold 'Em: During the Straw Hats' fight with Sentomaru, Admiral Kizaru and Kuma, Luffy makes the uncharacteristic call for them to make a tactical retreat. Completely and utterly Averted before that incident and afterwards though; in fact, since the Timeskip, he refuses to run away from even the most powerful of foes after realizing that he has to be stronger than them anyway to be the Pirate King.
    • Done again versus Katakuri. When you exhaust literally every option at your disposal and only manage to gain a temporary advantage that you lost the moment that he regained his bearings, were otherwise getting wrecked, and temporarily lost your Haki as a result of your final attempt to put the hurt on him, running really is your only shot at staying alive.
  • Knuckle Cracking: Tends to do this frequently.

    L-R 
  • Leeroy Jenkins: Does this whenever he's NOT trapped somewhere and can't fight, but the most notable straight example was at the beginning of the assault on Enies Lobby, where he actually took off full speed into the heart of Enies Lobby during the middle of planning, causing his allies to nearly be wiped out.
  • Leitmotif: Luffy Eyecatcher.
  • Lethal Chef: Don't ever let him near a kitchen. His attempt at cooking in chapter 824 resulted in the stove exploding since he forgot to turn it off. What he cooked was a complete mess of a "curry" made from jam, uncooked rice, fishbones and God knows what else that brought tears to everyone and that not even he could stomach. And he messed up so often while making it that he blew the entire group's week's worth of food in one go.
  • Lethal Joke Character:
    • Compared to the likes of Pyromancy, immunity to sword slashes, nullifying other Devil Fruit powers, and turning into a giraffe, stretchy limbs seems relatively low tier. That said, he makes it work. Word of God says that such an ability was chosen to keep some levity even in the most intense fights.
    • His latest Super Mode relies on his Balloon Belly feature. It inflates his body with so much air, he can't even stand still due to the bounciness. Even his opponent called it ridiculous. Until he got sent flying to the other end of the island in a single punch.
  • Lightning Bruiser: Possibly the fastest and most agile member of his crew, he also has incredible durability and strength. Word of God is that only Zoro matches his physical power.
  • Like Father, Like Son: While not spending any of his childhood with his father, he has nonetheless taken after him with his will and dangerous unpredictability, and both are stakes in the World Government's side.
  • Living Emotional Crutch:
    • Luffy is this to Ace, to the point that he says that he probably wouldn't want to live if it wasn't for him and Sabo.
    • He's also this to the aforementioned Sabo, who thanks him for being alive when they finally meet up again, as if Luffy had died, Sabo would've been left alone (like how Luffy thought he was when Ace died).
  • The Load: During combat and amidst crises, he's a stellar asset and an indispensable companion. During the actual travelling parts of the journey, he's terribly unhelpful to the basic upkeep of the voyage and has nearly starved the crew to death by gorging himself on their ship's food supplies.
  • Locked Out of the Loop: Luffy is generally ignorant of global affairs, but most of the Straw Hats are young and mostly unfamiliar with the places they visit, which often gets them into trouble. However, this is especially true of Luffy, who's known to jump in headfirst without knowing or caring about the situation. During the Time Skip, Luffy's training made him completely unaware of the major events taking place, some of which even involved his allies and his greatest enemies. These include: The massive bounty increases of his Supernova rivals; His own bounty increase; The vacated Warlord positions being filled, notably by Buggy and Law; His grandfather leaving active duty in the Marines; The duel between Aokiji and Akainu for the Fleet Admiral of the Marines position; The war between the Blackbeard Pirates and the remainder of the Whitebeard Pirates, which led to Marco's disappearance and Blackbeard's ascension to Emperor status. One wonders if Rayleigh had intentionally prevented such news from reaching him (especially the truth about Kuma and his agenda). Even Jimbei remarked on how harsh it was for Rayleigh to not tell Luffy about these things.
  • Magnetic Hero: Lampshaded by Mihawk:
    It's not some kind of special power, but he has the ability to make allies of everyone he meets. And that is the most fearsome power on these high seas!
    • Deconstructed in the Dressrosa Arc. Luffy tries his Magnetic Hero tendencies on the apparently reformed Bellamy, but for the first time... he fails. Bellamy refuses to turn on Doflamingo at this point since he's got nothing else to believe in, and not only does Luffy take some hard hits for his troubles, but wasting his time fighting Bellamy allows Doflamingo to gravely injure Law.
    • Played extremely straight at the end of chapter 799, where all the Corrida Coliseum warriors and their crews, which equal 7 divisions and 5600 crewmembers, ask to sail under Luffy and the Straw Hat Pirate flag. Even the aforementioned Bellamy, who still refuses to be Luffy's subordinate, parts on good terms with him and requests a piece of Luffy's Vivre Card just in case.
  • Manchild: A perfect example of the trope. Technically averted before the timeskip, as he was still a teenager, but played straight afterwards. His particular brand of Asexuality also serves to hammer this home; he's arguably even less interested in sex and gender roles then you'd expect even a typical 9-year-old to be.
  • Man of Kryptonite: Luffy is this to Enel, the main antagonist of the Skypiea Arc, and a Logia user with godlike powers who claimed to be God. Luffy's rubber-like body is capable of negating Enel's Goro-Goro-no-Mi powers completely, resulting in Enel being humiliated beyond belief when on the losing end of a Curb-Stomp Battle.
  • Meaningful Name: With a name such as "Luffy", he's certainly a born ruffian. And of course, his simplistic, hyperactive, and fun loving nature brings to mind certain species of Monkey.
  • Mighty Glacier: His second Gear Fourth form the "Tank Man" is this, as it sacrifices the Boundman form's mobility for even more power and defense. He first gorges himself with food and then inflates his belly (and muscles) to massive proportions and is able to use its elasticity to harmlessly absorb Charlotte Cracker's sword along with his whole body and shoot him out at high speeds.
  • Missing Mom: His mother is completely unaccounted for. Famously, the subject came up in an SBS, where Oda teased that we've seen her, but he won't say who it is.
  • Morality Pet: To Hancock. Until he met her, Hancock's surrogate mother Nyon was worried that she had become as cold as she appeared, but fortunately, Luffy's interactions with her proved that this wasn't the case, and brought up Hancock's better qualities.
  • Multiform Balance:
    • Normal Luffy is a Jack-of-All-Stats (still a Lightning Bruiser compared to most people).
    • Second Gear turns him into a Fragile Speedster / Glass Cannon. He's faster and hits harder, but his endurance stays the same.
    • Third Gear makes him a Mighty Glacier. The offensive and defensive power of the inflated body parts goes through the roof, but Luffy's speed takes a sharp drop.
    • Fourth Gear - Bounce Man combines the strengths of Second Gear and Third Gear which turns him into a Lightning Bruiser of the highest degree. He can use this form only for a short time though, and it takes a massive toll on his body in the process.
    • Fourth Gear - Tankman transforms Luffy into an even bigger Mighty Glacier. It allows him to No-Sell Haki-imbued piercing attacks and he can counter with enough force to send the attacker flying to the other side of an island. But he's practically immobile in this form.
    • Fourth Gear - Snakeman makes him a Fragile Speedster whose lightning-fast, ricocheting fists get even faster and practically home in on his target. While very hard to predict and counter, even for someone with incredible Observation Haki, the form leaves Luffy wide open for direct attacks, and he lacks the defense of his other Fourth Gear forms. However, it should be noted unlike Tankman, this is only in comparison to the other two Gear Fourth forms, he's still a Lightning Bruiser compared to his normal form.
  • My Favorite Shirt: His Nice Hat serves as a #1 Dime for him, and is also his Berserk Button when targeted.
  • My Greatest Failure: Not being able to save his brother Ace from being sentenced during the Paramount War. It motivates him into becoming stronger for the next two years.
  • Next Tier Power-Up: His fighting skills have continued to evolve as the series progresses:
    • In the Enies Lobby arc, he revealed two new fighting techniques called Gears, with Second Gear making him a Fragile Speedster and Third Gear turning him into a Mighty Glacier.
    • During the Time Skip, he learned to utilize the three forms of Haki.
    • While fighting Donquixote Doflamingo, he unveiled a Fourth Gear which is essentially a Super Mode that makes him a Lightning Bruiser. As the other two forms are revealed, it's revealed they're essentially upgraded versions of his Gear Second and Gear Third.
  • Nice Guy: He's usually friendly, cheerful, and amiable. Just don't touch any of his friends, his meat, or his straw hat.
  • Nice Hat: It's even on his Jolly Roger! It Was a Gift from Shanks who used to have the hat. And one flashback shows that what seems to be the same hat was what Gold Roger himself wears when he starts his journey.
  • The Nicknamer: Luffy has a habit of giving child-like nicknames to those he meets on his journey.
  • Nigh Invulnerable: His latest Super Mode jacks up his Lightning Bruiser to the extreme, but most notably his durability; nothing has been shown to damage him while it lasts.
  • No Badass to His Valet: The world sees Luffy as a dangerous pirate with a massive amount of potential and as one of the frontrunners to become Pirate King. His crew also sees him as that, but they also see him as their idiot captain who wouldn't last five minutes in the Grand Line, let alone the New World, without them, not due to any lack of ability, but due to his recklessness and outright stupidity. Rarely does Luffy ever act like he's the captain of the crew with all the abuse he suffers at their hands - unless when the situation is really dire.
  • No Challenge Equals No Satisfaction: Luffy would rather give up being a pirate than have the location of One Piece handed to him because there is no adventure in that.
  • No Good Deed Goes Unpunished: He begins his then "pirate" career by beating up four officially wanted pirates, (Alvida, Buggy the Clown, Don Krieg, and Arlong) dangerous by the standards of East Blue, and rather than giving him thanks (and the posted reward) for doing so, the Marines go and slap a $ 30 million bounty on him, and continue to antagonize him at every opportunity, raising his bounty if he so much as complains, let alone defends himself, up to and including threatening members of his crew, and framing him for attempted murder. He completely loses all patience on the last two. Ironically, the World Government and Marines think he is unforgivable despite owing their very existence to him several times over.
  • No-Holds-Barred Beatdown:
    • Pre-Time Skip he was subjected to a number of these. Post, he's been handing them out with impunity, beating the crap out of Hody Jones with only one major wound (and Jones only managed to land it because Luffy was underwater, had his movements restrained by a bubble, and trying to prevent a Colony Drop from destroying Fishman Island). Caesar Clown similarly got his ass kicked without even managing to land a single hit on Luffy.
    • With the reveal of Fourth Gear, he delivered one of these to Doflamingo.
  • Normal Fish in a Tiny Pond: Inverted; like Zoro and Sanji, he was a Big Fish in a Tiny Pond in both the East Blue and Paradise (IE the first half of the Grand Line). At the beginning of the series, Luffy was already strong enough to defeat all of his opponents without exerting himself at all. It wasn't until the Rob Lucci fight that we saw somebody really push him to his limit, but with his victory over Lucci, Luffy was thought by both his crew and citizens of Paradise to already be a very powerful pirate. In fact, if it weren't for Ace's capture, Luffy would've set sail into the New World at this time. Come the Marineford Saga though, Luffy gets a taste of New World-level threats and it becomes clear that he was nowhere near as strong as he thought he was. Cue a mental breakdown, recovery, and two years of training in an effort to catch up to the real big fish.
  • Normally, I Would Be Dead Now: Though to a lesser extent than Zoro, Luffy often suffers what should be fatal injuries and yet lives through them with sheer determination. The most infamous and impressive example would probably be when he was impaled clear through his torso by Crocodile's giant hook hand; a bit of time to rest later and he was all better.
  • No-Sell: To blunt force (unless it's imbued with Armament Haki or from Nami or his grandfather) and electricity. Fourth Gear - Bounce Man allows him to No-Sell Haki-imbued blunt attacks and Fourth Gear - Tankman allows him to No-Sell Haki-imbued piercing attacks.
    • Post Impel Down, he's also immune to some, but not all, poisons.
  • No Sense of Direction: Not as terrible as Zoro's, but it's still really bad.
  • No Sense of Personal Space: Luffy's loving hug of frienship and gratitude for Hancock was quite genuine; too bad he did not realize that it meant a lot more to the poor girl.
  • No Shirt, Long Jacket: Post-Time Skip, Luffy replaces his vest with an open-button jacket.
  • Not Afraid to Die: Luffy has no fear of death at all. This is a trait shared by every D. carrier shown thus far (save for Marshall D. Teach aka Blackbeard). Smoker, who witnessed Gol D. Roger's execution, saw how close Luffy was to meeting his own end on the same scaffold before his miraculous survival, made it his utmost priority to capture Luffy.
  • Not the Fall That Kills You: Luffy cannot die from a fall, no matter how high he drops from.
  • No True Scotsman: A pirate variant. Has a brief argument with Nami regarding this trope when discussing Kuro, whom he considers unworthy to be a pirate.
  • Oblivious to Love: He has no idea how Hancock feels about him. After the time-skip, he knows how she feels (he even assumes that when Hancock says she has a request, that it's a proposal and he preemptively declines it,) but to him she is a precious friend he would gladly die for, but Just Friends all the same.
  • Older Than He Looks: He's 17/19, but because of how adorably goofy and youthful he looks and acts most of the time, you'd be forgiven for believing he's younger than that. He looks even younger as the series goes on thanks to Art Shift.
  • One-Man Army: When Robin was being held in a government facility he charged head on into it, well ahead of his crew. The enemies numbered in the thousands. Luffy cut through them in mere minutes.
  • Only Known by Their Nickname: The number of people who call him Luffy is comparatively low to the number of people who call him "Straw Hat".
  • Only I Can Kill Him: Not so much kill, but it's pretty obvious there are opponents that only Luffy has the power to defeat. Eneru was a notable example. His crew members even point out that Luffy seems to have a knack for singling out the single most dangerous opponent in a group that the rest would have no chance against.
  • O.O.C. Is Serious Business:
    • Luffy is loud and proud and gives nary a damn if you tell him to clam up. For this exact reason, if he is ever deathly quiet for any reason, it's a sign that a fine line has been crossed and you want to be anywhere other than there.
    • As mentioned under Character Tics, Luffy usually smiles after defeating an opponent. But, after winning against his battle with Usopp, Luffy just has a look of sadness on his face...right before crying.
    • For an Idiot Hero who has always fought against the enemy, no matter how bad the odds were, this was pretty significant. So, if he tells you to run (i.e., his exact orders for his crew when faced with Kizaru), you'd do well to listen to him. It's a legitimate Godzilla Threshold moment.
    • Two of Luffy's main characteristics are his confidence and love of his trademark hat. So, in the aftermath of Ace's death, the former takes a huge plummet and the he doesn't even take notice that the latter is missing.
    • In chapter 844, after Luffy's fight with Sanji, Luffy tells his cook that he won't eat a single piece of food that isn't made from Sanji. That's right. Luffy is going on a hunger strike.
  • Otaku:
    • He displayed a surprising interest in beetles at Jaya and Skypiea.
    • And he remarks about things that are, "So cool/awesome!!!" Especially robots, cyborgs, lasers, any sort of beam weapon, cannons, and really ANYTHING you can relate back to Super Robot anime and manga.
  • Outside-Context Problem:
    • When Luffy started his pirate career in East Blue, he was an out-context foe for both pirates and the marines. Devil Fruits in the Blues are so rare that they are often believed to be mere myth and those who do have powers are seen as demons and monsters. So when Luffy, a rubber man, came along able to deflect bullets and absorb blunt blows without taking any damage, most of his early enemies didn't know what to do except for Buggy and Arlong, both who sailed the Grand Line where Devil Fruit users are more common. Buggy also have the extra benefice of being a Devil Fruit users who contrast Luffy's powers.
    • Luffy does it again during his battle against Eneru. Before Eneru met Luffy, he was completely unbeatable and most of his fights ended in a curb stomp. That is because Eneru had the Rumble Rumble Fruit that made him into living lightning. The fruit is so powerful that it is classified as unbeatable. However, since Luffy is a rubber man, he is completely immune to lightning. Even better, rubber doesn't even exist on Skypiea, so Luffy is also an out of context material. Eneru literally had no clue that a foe like Luffy could exist. The face he makes when he realizes that Luffy isn't affected by his powers is priceless.
  • Papa Wolf: Hurt a member of his crew – or for that matter, one of your own – and you are dead.
  • Paper-Thin Disguise: As "Lucy", which is really just him with an old-man beard and shades. Later, he takes off the shades for a gladiator helmet. However, this worked in his favor as it was more than enough to fool Doflamingo, when he switched out for Sabo to take his place.
  • Parental Abandonment: While not an integral part of his character, his father willingly left him to go help the rest of the world, his mother hasn't even been mentioned, and his Grandpa made no attempt to at least have him raised near him. Luckily, though, his foster mother and brothers made up for this void, and the only time he ever showed sadness over being lonely was in childhood before meeting Ace.
  • Personality Powers: Oda commented in an SBS that he gives his hero Rubber Man powers to reflect his fun, carefree and out-there personality, as well as to make a contrast to the more "serious" shonen heroes.
  • Person of Mass Destruction:
    • Pre-Time Skip, Luffy delt some pretty amazing feats of damage even before he had discovered Haki or his Gear abilities. In the anime Luffy's gum gum attacks combined with his super strength enabled him to TOPPLE WARSHIPS with his bare hands. e.i. ripping the bow off a ship in order to use as an impromptu weapon albeit while under strengthening hypnosis, drop kick and sink a tooled up battleship with ease, rend the mast off another ship and impale it upon a monstrously huge whale and to date one of his most horrendous feats of grit and strength; caused the massive upheaval between a deep cavernous temple all the way to the surface city plaza by rapid punching somebody through countless layers of bedrock all the way through to its surface!
    • Pre-Time Skip, he destroyed the top half of the Tower of Justice with two uses of Third Gear (the first made the Tower shake a little...and that was just by knocking a massive steel door down). After the Time Skip, he nearly destroyed the massive ship Noah by using haki-strengthened Third Gear. Keep in mind that Noah was in collision course with Fishman Island and Luffy would have almost certainly destroyed it were it not for the Sea Kings who stopped it.
    • Fourth Gear Luffy. His most powerful attack in that form split an entire city into two slabs and forced them upwards into the air. It'd be damn hard to argue it now.
  • Pintsized Powerhouse: While he's not overly short by Real Life standards, he tends to be rather puny in comparison to most of his opponents. He's 5'8", while his opponents range from above 6' to being freaking giants (literally!). Regardless, the large size disparity seems to make no difference for him; He's able to smack around a Pacifista (Cyborgs who are all about 22'6" feet tall) just as easily as he can smack around somebody like, say, Captain Kuro (an average sized human being). One of the best examples after the Time Skip is when he took on a giant (who appeared to be at least 70 feet tall) during the tournament at Dressrosa; he completely knocked him unconscious with a single punch.
  • Pipe Pain: When he was a child, he would use a metal pipe to fight since he wasn't very skilled with his powers at the time.
  • The Pirates Who Don't Do Anything:
    • Luffy's not interested in the typical "pillaging and plundering" pirate activities, but rather became a pirate for the sake of adventure. He fights with other pirates and the marines freely, but leaves civilians alone. Also, though he doesn't have any explicitly stated moral codes, he does lean towards only recruiting crew members who share his ideals on what it means to be a pirate.
    • In the Romance Dawn pilot, he says the Morgania pirates are the ones who pillage and plunder, while Peace Mains fight Morgania pirates and look for adventure. He is, of course, the latter.
    • Though he does cause lots of property damage, and he's not opposed to stealing available loot if an opportunity arises. Then there was that prison break...
  • Plot Armor: Lampshaded by Basil Hawkins. He tried several times to calculate a scenario which Luffy couldn't possibly survive, but Luffy always had at least a slim chance.
  • Pocket Protector: In the Adeventure of Nebulandia Foxy gives him a pin shaped like his (Foxy's) own head, and Luffy puts it on his hat; so naturally, it ends up catching a bullet for him later. The bullet in question appeared to be a more modern, cone shaped round that may have been capable of penetrating him; so, as the Big Bad of the special Lampshaded, Luffy really does have the Devil's luck.
  • The Power of Friendship: He always believes in his crew, even when they appear to betray or murder one of their own.
  • The Power of Love: At least half of everything Luffy has ever done in the series is driven out of the intense love he has for his crew. While undoubtedly selfish, there isn't anything in the world Luffy wouldn't do for their sake.
  • Power of Trust: Luffy is an excellent judge of character, successfully allying even with former enemies, both as permanent crewmates (Nico Robin, Franky) and as temporary allies (various other members of Baroque Works). It will be put to the ultimate test with his alliance with rival supernova captain-turned-Warlord Trafalgar Law (And it pays off. Law, despite his desire to end Doflamingo, moved to protect Luffy's crew).
  • Power Perversion Potential: Yes, everything stretches, as the inhabitants of Amazon Lily discovered.
  • Pride: Although he and the rest of the Straw Hats are nice people overall, he takes pride in the fact that he's a pirate no matter what the obstacle or how hated pirates are. This is evident in his first encounters with Nami and Zoro and he even calls out Captain Kuro for it.
    Luffy: So you say you can't take it anymore, huh? If you can't handle having your name out on the seas, then you shouldn't be a pirate!
  • Primary-Color Champion: He's the hero of the setting and this is his main color scheme.
    • Prior to the Time Skip, his standard outfit is a red waist coat with blue trousers and a yellowish hat.
    • After the Time Skip, he keeps the same hat and trousers, but now wears an open, long-sleeved red cardigan with four yellow buttons and a yellow sash tied around his waist.
  • The Promise:
    • He made one with Ace and Sabo when they were children to go out to sea and live their lives free of regrets. After Sabo's supposed death, Ace promised him that he would never die and leave Luffy alone. He was only able to keep the former, and he admits there was one regret that he did have: he wouldn't able to see Luffy accomplish his dream. However, unbeknown to both of them at the time, Ace didn't leave Luffy alone in this world — Sabo still lived, and made a promise to himself to inherit Ace's will and protect Luffy at any cost.
    • Not to mention the one with Shanks, that he'd return his Straw Hat to him one day after he became a great pirate. It is for this promise, Shanks refuses to see the injured Luffy at Marineford, as Luffy hadn't reached that level yet.
  • The Protagonist: He's the central or focal character in One Piece.
  • Raised by Grandparents: He was looked after by his grandfather during his youth.
  • Rapid-Fire Fisticuffs: His Gatling, Pistol-Shotgun, Storm, Fireworks, Cannon, Jet Gatling, Jet Cannon, Elephant Gatling and Hawk Gatling techniques.
  • Real Men Eat Meat: He loves it. He was once in a sleep that should have lasted for three days but he was woken up when Usopp yelled there was meat.
  • Red Baron: "The Fifth Emperor"
  • Red Is Heroic: Luffy's main color scheme is red.
  • Red Oni, Blue Oni:
    • Luffy is Red Oni, a hyperactive keet always ready to have an adventure compared Zoro's Blue Oni, being calm, calculating and cynical (most of the time).
    • Since forming an alliance with Trafalgar Law, he's become the impulsive, Hot-Blooded red to Law's calm, cold, clever blue.
    • To a lesser extent, Luffy is the red to any of his other crewmates' blue, as well.
  • Required Secondary Powers:
    • Luffy's inhuman strength compliments his devil fruit powers. The interesting thing though is Luffy gained this independently of the Gum-Gum Fruit.
    • Discussed during his fight with Rob Lucci. Second Gear was stated as a technique made by and only for Rubber Man, as normal human body couldn't withstand the increased metabolism, blood flow and strain.
  • Right Makes Might: If one has a strong ambition, one will always prevail in the end.
  • Rubber Hose Limbs: Since he ate the Gum-Gum Fruit, his limbs were transformed into rubber, so they can strength any way he likes.
  • Rubber Man: Thanks to consuming the Gum-Gum Fruit, and he refers to himself as this in exact words. He's more literally rubber than most examples, too. He can't stretch himself without momentum, and when he does, he snaps back into place like real rubber. His powers come with certain bonuses; his clothes automatically stretch with him, it takes incredible force to hurt him with blunt attacks without haki, bullets and cannon balls bounce off of him, he's highly resistent to electricity, his rubber bones can't be broken or cracked, and he rarely gets winded because his rubber heart and lungs pump more efficiently. Other characters comment that his power is "weird" even by Devil Fruit standards.
  • Rule of Symbolism: Curiously, Fourth Gear: Boundman. In that form, Luffy just happens to resemble a rubber version of a Kongorikishi, a wrathful, protector guardian deity in Japanese Buddhism. Word of God is that the form actually is inspired by that deity.

    S-Y 
  • Sacrificed Basic Skill for Awesome Training: So much. He's tough as hell, but he has absolutely none of the most basic pirating skills. Lampshaded as part of a Badass Boast when he fought Arlong.
  • Secret Legacy: The mysterious "Will of D." that several characters have mentioned. Goes a bit further when he's revealed to have Roger's hat and can hear the voices of Sea Kings like the man himself could.
  • Self-Harm: The scar under his eye is from a self-inflicted wound. It has nothing to do with emotional distress though, he was just trying to show off to the Red Hair Pirates that he was tough.
  • Series Mascot: Luffy along with Goku from Dragon Ball are the mascots for Shonen Jump.
  • Shared Family Quirks: Even before Garp was revealed as Luffy's grandfather, they both showed a Bunny-Ears Lawyer mentality, being more concerned with eating most of the time, often being absent-minded and a tendency to randomly fall asleep.
  • Shooting Superman:
    • Marines seem to love firing their guns and cannons at him despite the fact that they bounce right off and back at them every time. Especially jarring since you'd think that by now it'd be common knowledge that Luffy- a world famous pirate and most definitely one of the government's number one targets- is immune to normal firearms.
    • However, before he learned Haki, Luffy himself was guilty of this a few times. He had a tendency to charge headfirst into fights with Logia users even after it was clear he couldn't touch them. His very first fight against Crocodile comes to mind, where he spends five minutes punching him to no avail only to get impaled on a hook for his troubles.
  • Showy Invincible Hero:
    • Luffy earned the record-breaking bounty of 30 million berries for a rookie in East Blue where he won all his fights. Smoker being an odd exception to the rule. And the East Blue Saga covered a hundred manga chapters! Even in the early parts of his adventure in the Grand Line, Luffy’s win record continued and it seemed like nothing could stop him until he reached his goal. But then it was subverted. Repeatedly. And hard.
    • A more downplayed version appears post-Time Skip. Every fight Luffy had for the first three arcs were complete curb-stomp battles with him on the giving end, and he literally did not have a serious fight until the Dressrosa arc, and it was against an old, legendary pirate who used to fight with his grandpa back in the day, quickly followed by Donquixote Doflamingo, one of the Seven Warlords of the Sea. It's downplayed because in spite of this, both the audience and Luffy himself are well aware that he's still got a long way to go before he reaches his dream, and that it only gets harder from here on out. It's worth noting that said pirate, while incredibly strong, was long past his prime as he later admits, and that Luffy took on Doflamingo with the help of Trafalgar Law, and it was still his toughest fight to the moment until he engaged Gear Fourth. After that he had to start taking on Emperor subordinates to risk having his ass kicked again.
  • Shut Up, Hannibal!: Has done this numerous times against the Big Bads of the current arc. Prominent examples include against Arlong, Crocodile, Bellamy, Spandam, Caesar Clown and Doflamingo.
  • Signature Laugh: "Shishishi!"
  • Signature Move: The Gum-Gum Pistol, Bazooka, Gatling, and Balloon are his 4 most iconic moves, although he typically uses their Second Gear's versions now.
  • Sins of Our Fathers: Luffy's first and greatest crime was being born into the world, for his father is the world-renowned criminal "The Revolutionary" Monkey D. Dragon; a predicament similar to that of his adopted brother Ace, their existences alone being sins in the eyes of the world. Unlike Ace, however, his parentage doesn't really bother him all that much — partially because stuff like that never mattered to Luffy, and partially because Luffy didn't know he even had a father until he was seventeen. He also kind of suffers this under the fact that his grandfather is Garp, and at least one pirate, Don Chinjao, has a vendetta against the old guy and considers having it at Luffy is enough for revenge.
  • Smart Ball: While some of the times he's right are the result of his bizarre or poorly thought out guesses being correct, there are times when he's more reasonable than usual, such as when he tells Vivi that people will die no matter what she does, and defeating Crocodile, rather than intercepting the rebels, is the surest way to stop the rebellion.
  • Spanner in the Works: Quite possibly the greatest version of this trope. Ever. Without going into detail, let's just say that most of the arcs, movies, and video games involve him entering the scene and completely ruining the villain's plans right when they're about to be finished. Every time.
    • More often than not, he never even went in intending to stop the villain or knowing the villain even had an evil plan. He is literally just an unexpected variable that happened to mess up the scheme because the villain did just ONE thing wrong. That thing is usually trying to preemptively eliminate him.
    • Reversed with Blackbeard's master plan. Everything Luffy did just worked in favor of Blackbeard's plans, even speeding them up significantly, the most obvious example being the Impel Down incident.
    • Doflamingo attempted to take advantage of these tendencies in order to screw up Law's plan. He correctly deduced that Luffy would immediately be sidetracked by a tournament to win the Flame-Flame Fruit, most likely to ensure that his brother's power did not end up in the wrong hands. It would've worked, but it backfired magnificently when it created another Spanner to screw up his plans: Sabo, who takes Luffy's place in the colosseum in order to the win the Flame-Flame Fruit, being perhaps the only person outside of his own crew that Luffy would allow to take its power. This can be largely blamed on Doflamingo, as the tournament was most likely the main reason Sabo was in Dressrosa in the first place. It's at this point you can honestly say that anything even remotely related to Luffy has the potential to be this for any villain.
  • Spell My Name with an "S": He's known as Ruffy in some foreign editions, most notably the German translation.
  • Spider-Sense: He's one of the many people with Observation Haki, an innate power that allows him to sense imminent danger, see people's "auras" (outline) through walls, and hear the voices of any living creatures around him for at least several miles.
  • Stock Shonen Hero: The Trope Codifier of the "new generation" of Shonen heroes of this type alongside Naruto. Luffy is the Idiot Hero and a Leeroy Jenkins of a caliber so major that the rest of the cast tolerate him only because he is very good at fighting and The Heart of the crew. Still, the only time so far that his incredible drive to keep on fighting and his on-the-spot inventiveness failed him was during the Marineford arc, which was a massive Wham Episode.
  • Straight for the Commander: While the other Straw Hats fight the subordinates, Luffy usually takes on the Big Bad (or strongest opponent) of each arc. The other Straw Hats usually let him do this because they know he's the only one who has a chance against said opponent.
  • Straight Man and Wise Guy: The Wise Guy to Law's Straight Man. They go on a great tear in 748, with Cavendish and Zoro in the middle of it all. Also, more commonly, the wise guy for the entire crew's straight man (but most notably Nami or Usopp).
  • Strange Minds Think Alike:
    • After Luffy's explanation on the difference between pirates and heroes – heroes share meat, pirates don't – which Zoro was not there to hear, Zoro gives an incredibly similar analogy, except he substitutes booze for meat.
    • When Luffy and Nami are captured, imprisoned and restrained by Big Mom's crew, Luffy intends to get out by tearing off his arms, which is very similar to Zoro, who intended to cut off his legs to escape Mr. 3's Giant Candle Service Set.
  • Super Drowning Skills:
    • The most common victim of the Devil Fruit users in his crew. Of course, he couldn't swim even before getting his Devil Fruit powers, hence why Shanks's crew nicknamed him "Anchor".
    • Ironically, post timeskip he is one of the few Devil Fruit users who can overcome this. He has proven able to utilize Gear Third underwater, albeit far weaker. (He still swims about as well as a block of cement, however.)
  • Super Gullible: He is the only one besides Chopper who is gullible enough to fall for Usopp's Sogeking disguise.
  • Super Mode: He has a few of these techniques, which he dubs "Gears";
    • Second Gear is achieved by him pumping his blood with his leg (pre-timeskip) or just by yanking up his limb hard enough (post-timeskip) to highly increase blood flow and metabolism, giving him a glowing pinkish appearance and hot steam coming out of his body; this increases his strength and speed to dramatic levels, at the cost of his lifespan (because his organs work multiple times harder than normal), although this drawback is minimized post-timeskip.
    • Third Gear is achieved by him blowing air into his bone hole (after biting his finger first). This gives him hardened bone structure (to the point that bullets ricochet off him as opposed to bounce away) as well as enlarged limbs, but this makes him move slower, and he becomes Super-Deformed and weak for a minute after the mode stops. Post timeskip the drawbacks has been minimized; now he can keep the air insides his bones in only the places where he needs it, making him more flexible.
    • "Fourth Gear, Boundman" is activated by blow air into his muscles, combined with Armament Haki. It turns him into a rubber version of a fighting deity. He uses the full potential of his body's elasticity here, and combines it with his Armament Haki, retracting his limbs to launch them with absolute force, fly, remotely guide his punches, and increasing his durability to new levels. He developed this state in order to continuously fight the powerful beasts in Rusukaina, the island he trained during the 2-year Time Skip. However, it has a strict time limit and if Luffy goes over it, he'll be unable to use Haki for a good 10 minutes and be barely able to move during that time, leaving him extremely vulnerable. That said, eating a lot of food can easily counter this weakness if the opportunity presents itself.
  • Super Reflexes: Like many characters, he has them and developed them through sheer training
  • Super Toughness:
    • His rubber body nullifies all but the most powerful blunt blows (though Haki-imbued attacks strike him as if he were normal). One of the best examples is what he endured facing Crocodile. He was stabbed with a giant hook, drained of all the fluid in his body, poisoned, cut by Crocodile's extremely sharp sand, and physically beaten all over the course of 24 hours; yet he survived with just some bruises and cuts. However, though his toughness is certainly partially from his Devil Fruit, knowing Luffy it's highly likely he'd be Made of Iron even without it.
    • It has to be noted that he's reached completely insane, almost Whitebeard-esque levels of endurance by the time of the Whole Cake Island Arc. First, he takes a beating and fights for 11 hours straight against the 860,000,000 bounty Sweet Commander Charlotte Cracker, which included nearly getting his arm cut clean off. Then, he takes an extremely severe, Diable Jambe enhanced beating from Sanji, knocking out his tooth and rendering him briefly unconscious (which almost never happens to Luffy). Then, he almost immediately gets beaten to a pulp again by random Charlotte Family members with Haki-enhanced punches. Then, he draws blood from nearly tearing his own arms off in an attempt to escape Big Mom's prison. Then, he gets set on fire in the process of being freed from prison by Jinbe. Then, he takes more injuries fighting off guys on the way to meet Sanji. Then, after a brief few hours of recovery, he starts taking his worst beating yet to that point while fighting the implaccable, billion bounty man that is Charlotte Katakuri for another 9+ hours — including surviving an attack that blows a considerable chunk of flesh right off his torso. He's took all of this damage in one arc... and got back up each and every time.
  • Superpowered Evil Side: Subverted with Nightmare Luffy. He's a scary, giant, evil-looking Hulk-like figure, and Nami and Usopp were initially afraid of him, but he's actually still Luffy on the inside. Just REALLY serious. However, that could be something to do with shadows inside him, since Usopp and Nami noticed he behaves differently.
  • Superpower Lottery: No, really. When you actually look at all the different ways Luffy is able to use his Devil Fruit, it's quite possible that the Gum Gum Fruit might actually be one of the strongest of the Paramecia class, or at least the most versatile of the bunch. True, his own creativity is a huge reason for that, but the sheer fact that he was able to develop a technique as insanely strong as Fourth Gear due to the fruit's powers shows that it's nothing to scoff at. Heart Is an Awesome Power, indeed.
  • Taking the Heat: By telling Big Mom he was the one to ruin her candy factory and ate all her candy, he earned her rage, which would have gone to destroying Fishman Island. It was a lie and Big Mom suspects as much but won't try to disprove him.
  • Tastes Like Friendship: Although his friendship with them grew for different reasons over time, it only took Nami and Rebecca some food for him to instantly start to like them. The latter case is lampshaded when Law expresses annoyance that Luffy's fighting for Rebecca's sake because she gave him food.
  • Tears of Joy: Can only burst into tears when, in chapter 731, Sabo reveals he is alive.
  • Teens Are Short: Subverted. Just about every other teenager in One Piece except Luffy is tall. Though he's not terribly short by realistic standards, being 5'7 at first and later 5'8, it's obvious the average height for men in One Piece must be around 6'3 since everybody towers over him. Even civilians are typically much taller than him.
  • Teeth Flying: Luffy loses a tooth after getting kicked in the face by Sanji- and unusually for One Piece, it stays like that for several chapters/episodes. Fortunately though, he eventually drinks some milk and it just grows back. Luffy himself also tends to do this to his opponents, usually after hitting them with the finisher.
  • Terrible Artist: Luffy attempted to paint his logo on the Going Merry. The rest of the crew hated it so much they had Usopp paint over it. Later, he successfully paints his logo on Laboon. It looks as competent as you'd expect for this trope. Later still, his drawing of what the crew's shipwright should look like freaks out both Usopp and Sanji.
  • Thanks for the Mammary:
    • Luffy accidentally gropes Boa Hancock when he was hiding under her dress since how he was latched onto her kept her from walking straight. The act certainly affects Hancock, but she was forced to hold up her facade in front of the Marines.
    • Taken Up to Eleven when he's catapulted into the room (and chest) of Princess Shirahoshi... who is one of One Piece's giant characters. Before he realized it, he thought that he's standing on a giant pudding.
  • Third Time's the Charm: Against Crocodile, though there is a case to be had in his confrontations with Eneru and Rob Lucci. It takes him four separate rounds with Doflamingo before he finally beats him.
  • Time to Unlock More True Potential: By the end of the first half of the series, approx. time around the Sabaody Arc, his skills and power are simply no longer enough to beat anybody or anything stronger than a single Pacifista (with the support of his entire team at that...). Thankfully, he got better and after two years of training, he can now also defeat a Pacifista in a single hit (along with a giant Kraken, for that matter...).
  • Tired of Running:
    • In Chapter 798 he takes on Admiral Fujitora instead of escaping as he's tired of having run for two years. As he correctly pieces together, he really has no choice but to face the Admirals and Emperors if he wants to become the Pirate King, after all.
    • He does it again when Nami begs him to run from Charlotte Cracker, an Emperor's right-hand man with an 860,000,000 beri bounty. Luffy refuses and, sure enough, he's eventually able to beat him.
  • To Be a Master: His dream is to become King of the Pirates.
  • Too Dumb to Live: Indeed. He would have been killed many times if not for incredible strokes of luck and allies who are willing to save his ass. In some less dangerous situations he knows what he does, but his problem is that he has no fears and fails to recognize true danger.
  • Took a Level in Badass: BIG TIME during the Time Skip. To the point that he hasn't had a real challenging fight since the Time Skip ended until the Dressrosa arc.
  • Top-Heavy Guy: When he activates his Fourth Gear. He also appears like this when using Gum Gum Balloon.
  • Trademark Favorite Food: Meat. Any kind of meat (Although he's not as fond of seafood, as revealed by the Fishman Island arc). Eating it even makes him stronger, and if he's not fighting or playing, he's always seen eating meat. To the point that, in a crossover with Toriko, when he orders a 3 course meal, ALL of them consists of meat. Even the drinks.
  • Tranquil Fury: If you piss him off enough to make him enter this mode, you're screwed. Luffy usually starts his fights in Unstoppable Rage mode, and finishes them in Tranquil Fury mode, when his enemy has really pissed him off.
  • Training from Hell: Went through this in childhood. It involved being thrown into jungles at night and tied to balloons, apparently.
  • Trauma Conga Line: The Paramount War is one HUGE Break the Cutie moment for our hero, starts during the Sabaody arc, gets many times worse in Impel Down, AND he finally rescues his brother only for that brother to lose his life protecting him, he is VERY LUCKY that he is able to return to being himself.
  • Through His Stomach: A surefire way to get Luffy to be your best friend.
  • Trouser Space: Where he keeps the "octopus"...
  • Tyke Bomb: A technically non-villainous example (well, depending on how you view the Marines); Garp put him through some brutal training as a child so he could be prepared to be a Marine as soon as he was old enough to join. As a result, he was already strong enough to beat up grown men and wild animals at age 7 and could casually shatter stone with a punch by the time he was 14.
  • Übermensch: Luffy refuses to follow the typical code of pirates, a code that revolves around pirating for treasure rather than your dreams, and does not harm civilians and steal. On one occasion, this even got him ridiculed and beaten, but he still stands strong by his beliefs.
  • The Unfettered: The reason he's gotten as far as he has- his inability to hold back or restrain himself, is one of his most defining traits. His only fetter is his loved ones, especially his crew and the closest family to him.
  • Unskilled, but Strong:
    • Initially with regards to Haki; he starts out only being able to make people submit to his power, and only during the Time Skip does he learn how to use its forms.
    • Also, this is what many villains told him In-Universe during the Marineford Saga in regards to his abilities in general. His physical power and natural talent for combat was right up there with the best as usual, but... a combination of not having any sort of hardening or observation Haki at all, no knowledge of when they were being used against him, fighting against people even stronger and faster than he was, and most importantly, fighting against people who could actually negate his strongest attacks (such as Magellan) for the first time led to a long line of defeats. Thankfully, he's gotten better.
  • Unstoppable Rage: On Enies Lobby, the soldiers were literally being sent flying by the hundreds from the moment Luffy got there, and it wasn't over until 3000 had been defeated and he had made his point — shit was getting serious. He switches into this mode fairly frequently at the climax of his battles every arc.
  • Victory by Endurance:
    • Defeats Z this way in One Piece: Film Z, as their fight eventually devolves from using their powers/weapons to just flat out hitting each other until one of them fell.
    • There's also a case to be had with the Rob Lucci fight, as Luffy wins by pushing himself to his absolute limit to knock Lucci out with one final attack when they're both already exhausted.
    • His duel with Katakuri. While Katakuri is faster, stronger, more skilled, and overall the better combatant, if there was one thing Luffy was better than him at, it was taking hits. Luffy took advantage of that, dodging and tanking Katakuri's hits until his Observation Haki advanced far enough for him to start countering and even attacking. Finally, after over ten hours of fighting, the battle ended on a Double Knockout — but when they both get up, Katakuri falls down again while Luffy remains standing, giving him the win.
  • Wacky Parent, Serious Child: Inverted with him (goofy protagonist son) and Dragon (his serious father).
  • Wardrobe Wound: Most of the damage he incurs is of this variety.
  • "Well Done, Son!" Guy: A younger Luffy wanted to be friends with Ace, the older kid living with him, and Ace's friend Sabo, who found him to be a weak, annoying crybaby, and lead him into tons of deadly situations to escape him, but he kept coming back. Eventually, Luffy shows how tough he really is, and they become brothers.
  • When All You Have Is a Hammer...: Most of the situations he's gotten into have been solved through liberal use of punching the right guy in the face. Prior to Marineford, it's typically his only strategy, many times literally just asking whose ass he has to kick. It's fitting, as one of his stronger techniques is also called Gum Gum Mallet and Gum Gum Giant Mallet, which both mean hammer.
  • Wild Card: As the Captain of the Straw Hats, an entire crew of Wild Cards themselves due to the mangling of the power balance they've done over the past two years, he is one himself. Hell, considering his reputation for being a Spanner in the Works and his general unpredictability, he counts greatly. Sometimes he's unpredictable even to his own crew.
  • With My Hands Tied: He one-shoted Vander Decken with his arms chained.
  • The Worf Effect:
    • Generally speaking, every time Luffy grows stronger or gains a new ability, his next opponent will counter or match his new power to show how much more dangerous they are than the last foe.
    • The Whitebeard War Saga (from the Sabody Archipelago arc up until the Timeskip) basically inflicted one continuous Worf Effect on Luffy; from Boa Hancock smashing Pacifistas effortlessly (while Luffy needed his whole crew to beat one) to Smoker no selling the Jet Gatling Gun (which was his strongest Gear 2nd move at the time), the entirety of the saga mocked the notion that Luffy was any kind of threat to the top tier powers in the New World. Cue two years of training to catch up.
    • Of particular note is Big Mom, one of the four Emperors and most powerful people in the world. At the time of their first confrontation, Luffy had just recently defeated Donquixote Doflamingo and Charlotte Cracker with Gear 4th, easily overwhelming them with the raw strength of his Next Tier Power-Up even though they were perhaps his two toughest opponents yet at that point. Doflamingo, in particular, was sent flying the length of a city despite attempting to block Luffy's punch with his Haki on and both arms up. Now, in comparison, Big Mom blocks the exact same punch with one Haki-covered elbow and wasn't pushed back an inch from where she stood. She then laughs at the notion of Luffy being able to defeat her or Kaido, showing how powerful the Emperors really are.
  • The Wonka: He's the captain of the main crew, and has accomplished several feats using a lateral or outright insane branch of logic, so he qualifies as this.
  • World's Strongest Man: Not yet, but his dream is to become King of the Pirates, which by default means wanting to become this.
  • Worth Living For: After Ace's death, the only reason Luffy found the resolve to keep on living was because of his crew and the fact that Ace would've wanted him to live and move on. Otherwise, Luffy would've probably turned into a Death Seeker, a clear indication of just how bad his Heroic B.S.O.D. was.
  • Worthy Opponent:
    • Smoker. This has become especially apparent when Smoker was willing to transfer into the worst marine base on the Grand Line, just so he could wait for Luffy in the New World. He waited two years for someone that the world thought dead, because he knew that Luffy would return to the sea sooner or later. Luffy sees him this way as well, as when Smoker was stuck in Tashigi's body Luffy refused to fight him until he was at full strength.
    • Charlotte Katakuri. Unlike a lot of Luffy's foes, Luffy made no move to insult him and instead purely based his judgement on Katakuri's abilities as an opponent. This was even after Katakuri's physical and personality flaws were revealed to him. Eventually, this respect is returned, and after their fight concludes, Katakuri acknowledges that Luffy might very well defeat Big Mom and become the Pirate King. As a final gesture of respect, Luffy takes off the mafia hat he was wearing over his regular one to cover up Katakuri's disfigured and fanged mouth, a feature the man himself is deeply ashamed of, to hide it from the remaining members of his family.
  • Would Hit a Girl: Examples include Alvida, Ms. Valentine's Day, Vivi (as Ms. Wednesday and later in a Get a Hold of Yourself, Man!), Boa Marigold and Sandersonia. Of course, the women he occasionally fights are all dangerous, and it wouldn't be wise to go easy on them.
  • X Marks the Hero: He got an X-shaped scar across his chest from Akainu's attack at Marineford.
  • You Are Not Ready: Marineford is where it's driven home that no matter how lucky or determined Luffy is, there ARE people out there who are still in a whole other league above him, and trying to tackle them head-on is a really bad idea. He and his crew then spend the next two years GETTING ready.
    Admiral Akainu: If nothing else, I praise your tenacity.
    Admiral Aokiji: But you're not ready for this stage yet.
    Admiral Kizaru: There's no way you can beat us, you know?
  • You Called Me "X"; It Must Be Serious: If Luffy stops calling a character by the nickname he's arbitrarily given them, you know he's serious.
  • You Can Barely Stand: But he STILL got up and kicked Lucci's ass. Not against Magellan, however...
  • You Never Asked: The main reason why nobody knew that Luffy and Ace were not blood related is because nobody bothered to ask.
  • You Remind Me of X: Luffy frequently reminds others of Gold Roger, especially when he almost gets executed by Buggy in Loguetown and smiles even when he thinks all hope is lost, just like Roger had in his execution.
  • Your Size May Vary:
    • Luffy's iconic Straw Hat, through the many Art Evolution phases Oda went and experimented on, our hero's hat has gone from fedora sized to sombrero sized, though it's not an increasing constant, it may get smaller or bigger depending on the arc.
    • Luffy is generally supposed to be depicted as "slim, but muscular", but the anime occasionally makes him look even scrawnier than a pre-timeskip Usopp. Ironically, this seems to have become even more prevalent after the Timeskip.
