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, in Good Old Fisticuffs. He ate the "Gum-Gum" Fruitnote  at the age of seven, giving him stretching powers that he has become quite a master of and he's quite creative with them, as he has developed two techniques with them: Gear Second, which makes him much faster, and Gear Third, which allows him to inflate any body parts for a stronger atttack. During the time-skip, he has a new technique: Gear Fourth, which makes him much stronger and faster than even the other two Gears, but with a time limit, after which he's unable to fight for ten minutes. 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) is also revealed to the masses. For this, certain circles now unofficially consider Luffy the Fifth Emperor of the Sea and he 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 


    open/close all folders 

    #-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, and so far he has only given it to Nami and Usopp. Likewise, if someone ever dares damage it, ass will be kicked in great quantities. When he gets struck hard with Heroic B.S.O.D. during Marineford arc, he gets so distraught that he doesn't even realize that his hat fell down; Shanks finds it and then tells 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 gets 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 and he still remember Akainu. It doesn't help that he's also the one who has killed Ace, his brother.
  • Achievements in Ignorance: How he becomes the "Fifth Emperor" and receives his ridiculously high bounty. The Straw Hats only enters Big Mom's territory to get Sanji back, and only involves themselves in Bege's assassination plot to save Sanji's family. The subsequent "raid" on Totto Land is 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 are to get to Sanji and protect the crew, respectively. They are so focused on rescuing Sanji and escaping Totto Land, that none of them (except possibly Jimbei) realizes 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 has 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 tends to follow orders more than give them, prompting several characters to point out that Nami acts 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 (Eìespecially 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 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 has 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 have been 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 (usually just being nice to him, especially by giving him food). 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 Gear Fourth 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 Rokushiki's Geppou, not to mention Soru. The other variants tend to combine the above spring powers with either Gear Third (like 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's been regularly defeating people who should ostensibly have been way stronger than him on paper- yet he would never publicly get credit for it, partially because the World Government has hidden some of his achievements and given to someone else, like Crocodile's defeat. By the midpoint of the series however, this begin to be generally Subverted as he come 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 defeat an Emperor's top fighter (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 tends to rise whenever there is a crisis involving the women of the crew. He gains his initial bounty when he beats Arlong and liberates Nami from his control, it rises when he defeats Crocodile and helps save Vivi's country, and has 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 causes 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 ends up with another bounty increase – something remarkable, as three hundred million is largely considered the cap for a rookie pirate such as Luffy. Played with in his fourth rise, a result of beating Doflamingo, with his primary motivation is to avenge his friends who has suffered because of the Warlord, even though the original plan is to just destroy the SMILE factory and let Kaido's rage do the rest.
    • It's also how he become the "Fifth Emperor" — Luffy and co. enteres Big Mom's territory to get Sanji back. That being said, the mission is supposed to be undercover and undetected but they endes 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) causes it to escalate to an assassination attempt on Big Mom and then a full-scale conflict that engulfes the entire archipelago. The crew is so focused on getting Sanji and escaping Totto Land alive that none of them realizes 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 has 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 is a criminal in name only. He's sometimes a bit rude, and beat up "good guys" who really deserves it, but that is 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 even human weapons (on one occasion) and destroys public property freely in his many battles.
    • 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 agrees to be one after Jimbei promises 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 is being a student of Silvers Rayleigh. The results of training with Gol D. Roger's number two are quite evident.
  • Arch-Enemy: He has made a lot of intimidating enemies throughout the entire serie. The two that stand out from the rest, Blackbeard and Akainu, have one thing in common: they've 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... all with the prefix "Gom Gom". Mixes with Animal Theme Naming for Gear Fourth attacks.
  • Arson, Murder, and Jaywalking: During his Badass Boast to Arlong, he says he needs his True Companions because they can do things he can't, like using swords, navigating, cooking... and lying.
  • 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 observes the CP9 members using Soru, and he soon begins 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 stands in his path to Ace during the Paramount War, Luffy shows extreme reluctance at attacking him, all but begging him to get out of the way. It's only when Garp tells him that he has no other choice that Luffy goes 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 says that to one of The Seven Warlords of the Sea, right after he rebuffs 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 is also a Warlord and has an higher bounty than him.
  • Badass Family: When your grandfather is "the hero" of the marine and one of the strongest marines while your father is the leader of the revolutionaries and the world's most wanted men, you cannot be less than one of the most famous pirates. This extends to his foster brothers too: Ace used to be a division commander in the world's strongest crew while Sabo is the right hand man of the revolutionaries.
  • Badass Longcoat: Wears one in One Piece Film: Strong World to give him the appearance of a true badass pirate captain.
  • 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 is a Chessmaster and Person of Mass Destruction who has 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 tries sneak in and leave undetected, has gotten caught, suffers through some grueling battles for it, and nearly dies several times while just barely escaping Big Mom in the end. He also has nothing to do with planning the assassination (though he and his crew are the only reasons it gets as far as it does); that is all Bege's idea.
  • 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. However, he can act well if he's really serious about it.
  • 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. This become aDeconstructed 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 doesn't matter who was right or wrong during Luffy and Usopp's argument/fight, but they've both fought for their own belief of what was right and Usopp willingly left them. And, whether or not he agreed with Luffy, Usopp has 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 has done, it would be a captain letting a crew member walk over him instead of demanding respect.
  • Berserk Button: While he's generally nice and is easy to get friendly with him, there are some things that can make him really angry.
    • 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 learns 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 
    • 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. Try to push anyone of the above-mentioned berserk buttons, and he won't be afraid to declare war on you.
  • 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, a former enemy, 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 is 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 is absolutely devastated when Ace dies to protect him. One of the only reasons why Luffy never crosses the Despair Event Horizon after Ace's death is the realization that Ace has 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 chants his name and counts 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 are related of course, but they are very close and have made a ceremony of drinking sake and become brothers. Luffy is 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 tries 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.
  • 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 and it ultimately works when Cracker, tired of having all his biscuit soldiers eaten, decides to attack.
  • Born Lucky: Justified by having the "Will of D" He has been described as having the Devil's Luck. While the lightning bolt that saves 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 means he has a lot of potential – the only difference is that his takes 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, with Ace's death. Thanks to Jinbe, he manages to recover remembering he still has his friends. Afterwards he Took a Level in Badass and become even more determined to protect his loved ones.
  • Bring It: With the dub version, this is what goes down after the flag is 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!!!
  • Brutal Honesty: There are definitely more tactful ways to inform Tama that Ace is dead rather than bluntly telling her that. Tengu and even Tama herself call him out for this.
  • 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 Moment of Awesome, a few goes 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!" to the point that those unaware of his fame would never think he's the captain of one of the world's most infamous crews. None of his crew mates deny that he's an idiot and, at the same time, 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's 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 at the beginning of the story, 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 and 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.
  • Clark Kent Outfit: Before the Timeskip, the seemingly scrawny Luffy typically wears a closed vest that hides his surprisingly well built physique. Furthermore, like Zoro, his arm muscles are shown to grow much larger than you'd think when he flexes. After the timeskip, his vest is open, but he still appears scrawny.
  • 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. He's also interested in weird individuals like Brook, a living skeleton.
  • 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. During his fight with Katakuri, he masters it to the extent he can foresees some minor events.
  • 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 refuses to take advantage of the man's blindness. He doesn't pull his punches, but he does shout out his attacks and where he's aiming to give Fujitora a chance to react. The admiral is not amused to learn of this.
  • Coming-of-Age Story: Luffy's journey is to become the King of the Pirates and leaving his adoptive family behind and during the journey he learns how to become a proper pirate captain.
  • 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 turns into an advantage against Eneru, who can read minds. Luffy simply ricochets 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 non-canon 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.
  • Cuddle Bug: Luffy shows how much he loves his friends by hugging them, regardless of gender or race. 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 simple 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. Considering how powerul he has become thanks to the Gom-Gom Fruit, eating it was definetely worth the prize.
  • Curtains Match The Windows: Luffy has black hair and black eyes.
  • Dangerous Forbidden Technique: All his Gears carry significant drawbacks; Gear Second is Cast from Hit Points and Gear Third had the side effect of making him shrink and lose speed and mobility. After two years of training, he's overcome those weaknesses. His new Gear, Gear Fourth, 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 turns out to have survived, but that's a moot point considering he doesn't find out until 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 defeats Lucci with his Jet Gatling. And the 2nd one is to Jimbei while he's having a truly epic Freak Out! on Amazon Lily. Later becomes one of his regular abilities thanks to Haki.
  • Defeating the Undefeatable: Some of his opponents are enemies considered out of his league or that have proven to be almost invincible, but he still manages to win against them. However, it should be noted that he never defeats them on his first try.
    • The first example is Crocodile, one of the seven Warlords of the sea with a long experience as a pirate, and whose defeat at the hands of a rookie is considered impossible. Yet Luffy manages to beat him, but only after losing to him twice.
    • Enel is probably the best example, as he spend most of the Skypiea arc proving how strong he was by stomping every fighter he faces and surviving any attack (most of the time thanks to his [[Elemental Shapeshifter devil fruit's intangibility). The only reason Luffy defeats him is because he's the only one able to hit him and is completely immune to his electric attacks, and even then, Enel manages to have the upper hand most of the time.
    • Averted with Magellan. He defeats Luffy the first time they fight. During their second round, all Luffy can do is buy time to escape, and never defeats him. Not much later, during the Summit War, Luffy finds himself unable to defeat any of the strongest fighters; 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, a pirate who's been controlling the underworld.
    • 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: He's not the brightest bulb, so sometimes he's slow to react. It's used a lot of times for comedic effect.
  • Despair Event Horizon: Ace's death drives him to despair, to the point of being the only time, after a career of being a Determinator, where he's about to give up. 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 is a double subversion, because it all but kills him. He's healed by Ivankov, but the technique used is explicitly reliant on the patient's will to live and Ivankov is especially shocked that Luffy recovered in a few hours, despite his initial estimate that it would take days for Luffy to recover, if he recovers 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, as he's not afraid to attack any kind of authority.
    • 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 are 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: As if all the moments of stupidity in the story aren't enough proof of it,in one of the data books, his intelligence score is a whopping 1/5.
  • Dodge the Bullet: Despite being Immune to Bullets, he has extremely sharp reflexes and can also dodge bullets with ease, even light beams.
  • Does Not Like Spam: It's revealed, while fighting Katakuri, that Luffy hates mochi. He doesn't like when he has to eat through a mountain of it.
  • Dope Slap: Is the victim of this a lot due to his stupidity, especially from Nami.
  • 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 and has the highest bounty revealed so far. 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, usually when there are some conflicts.
    • In the Alabasta Arc, Luffy refuse to follow Vivi to Koza's main base as he states 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 suggests the crew get a shipwright to fix the Going Merry (despite him suggesting a musician after the crew is surprised by his words).
    • In Water 7, upon learning the Going Merry is on her last legs, Luffy make the tough call to seek out a new ship. And during his argument with Usopp, Luffy make three valid points. First, during his verbal argument with Usopp, Luffy points 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 can't follow his orders, before being stopped by Sanji. Thirdly, when Usopp challenges Luffy to a one-on-one fight for ownership of the Merry, Luffy choses to go through with it, and when Nami asks why he isn't trying to stop it, Luffy points out that he knows Usopp is dead serious about it and wouldn't be convinced any other way. Despite her misgivings, she doesn'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, and doesn't want to be a hero, he is a very good and mostly pure man. He will go out of his way to help people if they've been kind to him, and recognizes 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 does he get to Marineford? Well, it overlaps with Big Damn Heroes, 'cause he drops a ship out of the sky! (It isn'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. Like Franky's goofy gadgets.
  • Elemental Punch: His unique rubber body allows him to do two types, fire and lightning. The first is used in his attack "Red Hawk": when the heat from Second Gear is combined with haki on his arm, it lights on fire; this attack is also a tribute to Ace. As for the lightning, he can absorb the lighting during a storm into his limbs (since rubber is an insulator) and attacks with it, this one has only been used in the movie Strong World against Shiki.
  • Enemy Mine: Seems to have a knack for pulling this off, even in the most unlikely of cases, such as with the old antagonists he meets again in Impel Down or with Capone Bege in the Big Mom assassination plan, despite making clear, in the latter example, that he'll never forgive him for shooting Pekoms, and still helps Bege when the latter is protecting his crew and the Straw Hats from the emperor's attacks.
  • Enhanced Punch: Luffy's main attacks are punches, which are given additional range and force by his Rubber Man powers and, using Gear Third, he can blow his limbs up to gigantic size for even more force. After the time-skip, he can imbue them with Armament Haki, making them even stronger and able to hit Logias. This is taken to a whole other level with Gear Fourth.
  • 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, showing off how determined he his to become a pirate, 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 not close to him, with rare exceptions.
  • Everyone Has Standards: 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. However, the admiral doesn't appreciate it.
  • Experienced Protagonist: Has shades even though he undergoes some training for two years, Luffy is 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 a Crouching Moron, Hidden Badass when it comes to fighting. Incidentally, Luffy meets Goku in the Dragon Ball x One Piece - Cross Epoch crossover and he even gets 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: His main ones are his impulsiveness and fearlessness. As both have lead him in taking reckless and stupid decisions or attempting to do things out of his reach, and while sometimes these flaws are played for comedy, they can have some grave results. The worst result is when he punches the celestial dragon, which ends up with Kuma scattering his crew across the world in such a way that it looks like they've been outright atomized to him (Of course, this way Kuma has actually helped Luffy and his crew).
  • 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 is 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, is given the ability to stretch by Moria and uses some of Luffy's techniques against him. At the time though, Luffy has become "Nightmare Luffy" and completely overwhelms Oars, until the shadows comes out, then Luffy has to cooperate with all his crew to beat him.
    • Charlotte Katakuri invokes another 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 and wins by developing and becoming stronger during the fight.
  • Fearless Fool: More often than not, he never realizes how strong his opponent/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. In Sabaody, however, it causes his great
  • 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 starts developing during the arc, and Luffy's decision regarding their ship (which Usopp is very fond of); the conflict grows into fight between them.
    • Played for Drama, again, in the Totto Land arc. During the mission to retrieve Sanji, when Luffy finds the cook, he fights him to test if Sanji is really willing to leave the crew, or is only doing it to save his mates.
  • Fight Off the Kryptonite: Two notable occasions: In Alabasta, in Crocodile's Elaborate Underground Base which is flooded, he fights off Bananagators with Zoro and Sanji, as half his body is already underwater. Then in Fishman Island, most of his fight with Hody Jones has him at major disadvantage as he does it underwater. It was still ridiculously one-sided even before the fight is taken to a bubble-coated giant ship where he can 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, he becomes even faster than Soru, although he's slow to Kizaru. He has become even faster after the timeskip.
  • 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, where he's dashing to save his crewmate or his brother.
  • 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. The same can be said with Sabo.
  • Forgiven, but Not Forgotten: He's usually a nice guy who can befriend and forgive nearly anyone, up to and including former antagonists regardless of morality. However, he draws the line upon seeing Crocodile in Impel Down. He ends 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 for what he's done in Alabasta, despite Crocodile saying that he doesn't care about his old goals anymore.
  • Forgot I Couldn't Swim: This happens to a lot of DF users, of course, but its kind of a Running Gag with Luffy. Probably the most hilarious incident is when Chopper and Brook valiantly leap into the sea to rescue him, completely forgetting that their Devil Fruits make them'' unable to swim too.
  • Freak Out!: He completely freaks out when Kuma scatters his crew, and when Ace is killed. The latter is so bad, that sends him into an Heroic B.S.O.D. for a few days and, after recovering, he still freaks out and destroys everything until Jinbe snaps him out of it.
  • 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: He's generally nice to every weird creatures that catches his attention, at one point, he's 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 for the same amount time he inflated his body. He overcomes this weakness after the timeskip and can now use Gear Third without any drawback.
  • 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 comments that he's "unusually clear headed" during the Summit War, implying he's not as much of an airhead as he seems. He has 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 listed 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.
  • Good Old Fisticuffs: A straight example. To go with his simple personality and self-admitted inability at anything except fighting, he can't use any weapon nor doesn't practice any martial arts but resorts to simple punches and kicks, the most basic fighting style. Still, 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 left eye, which he self-inflicted when he was a kid to prove Shanks that he can be manly. After the timeskip, Luffy gets a new 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, although he's saved just in time, he smiles as Buggy is about to cut his head off at Logue Town.
  • Gratuitous English: Most of his attacks have English names, particularly his Gear-related ones.
  • 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.
  • 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.
  • He Knows Too Much: Boa Hancock makes him fight her sisters in an attempts to execute him after he sees the Slave Brand on her back. It doesn't work, but he understands that he must not reveal it to anyone.
  • Heart Is an Awesome Power: Sure, there are a lot of characters whose power is having the body made of rubber, but, his own strength notwithstanding, he can make such a creative use of his rubber body that he turns what seems a lame Devil Fruit into one of the strongest abilities, especially with his Gears. It's no surprise that Burgess attempts to kill him so he can get the Gom-Gom fruit.
  • The Hero: He is the main protagonist, after all. In terms of how much of a Hero he actually is, it's complicated, especially because he doesn't want to be one, 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:
    • 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.
    • 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 is taking Rebecca, and chase after him so that Fujitora wouldn't be able to destroy the ships the Straw Hats are using to escape, for fear of catching the civilians in the crossfire.
  • Heroes Fight Barehanded: He's the main protagonist, and 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 and is so traumatized to need to be taken by Jinbe and Law or he would've died. It takes a few days to recover.
  • Heroic Resolve: Has it in spades. No matter how bad of a beating he gets, he just keeps getting back up, frustrating the opponents he faces on his journey.
    • Crocodile beats him down no less than two times. He gets back up, albeit with help the first time and an incredible amount of luck the second time, but during their third and final fight, he absolutely refuses to yield against Crocodile, powerful Warlord or not.
    • Rob Lucci gives him an incredible beating comparable to what Crocodile does, but Luffy takes it all, refusing to fall until Lucci does.
    • Charlotte Katakuri gave him a beating that tops everything he ever suffered beforehand, but he gets back up again and again. While this resolve initially frustrates Katakuri, he eventually respects Luffy's resolve.
  • Heroic R.R.O.D.:
    • His Gear Second pre-Time Skip shortens his lifespan with each use, and will eventually wear him out if overused. Gear Third also might count, although it only shrinks Luffy temporarily after each use, with no mentioned long-term effect. He overcomes these weaknesses 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 Gear Fourth 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: Rob Lucci gives Luffy such an harsh beatdown to bring him on the verge of collapsing, but Usopp spurs him to get up, giving him enough strength to continue and defeat Rob Lucci.
  • 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 never leave story relevant scars, like his trademark one under his eye he gives himself in Chapter 1, his X shaped scar he gets from Akainu. For istance, he loses a tooth after taking a direct kick to the face from Sanji but, several chapters later when he drinks some milk and his tooth grows back on the spot and one of Capone Bege's mook comments that his body is weird.
  • Honor Before Reason: During the Davy Back Fight, the Straw Hats lose 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 than most examples, 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 Gear Fourth consists in him pumping air in his muscles, making them grow. In the Poundman version, he turns 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 and against most arc villains' in their first encounters). 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 (the latter of which Luffy considers nothing to get worked up over, as he and his crew were there only to get back a crew member that has been taken from them). It's also why Sentomaro recognizes the fake Luffy, Demalo Black, as an imposter, since the latter brags about his fame to everyone. When Sengoku tries to cover up Gekko Moriah's defeat by ordering Bartholomew Kuma to kill the Straw Hat Crew, Vice Admiral Garp tell 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!".
  • 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 sleeveless vest/blue shorts with sandals combo as well as his first Time skip outfit, which basically replaced the red vest with an open long sleeved one.
  • 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 and an SBS in 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 actually 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. For the most part, however, he's childish, naive and does things that noone with common sense would do, more often than not causing big troubles.
  • I Gave My Word: His word is the greatest thing he can give. He takes it seriously. How serious? He promises Robin he'd be her friend forever, so when she's taken from him, he goes 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 has given 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 tell him not to hurt any World Noble or when Law tell 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'. This also, apparently, a trait that comes with the Will of D.
  • I Let Gwen Stacy Die: Ace's death is this for Luffy, as he fails save him after all the troubles he's gone through and the sacrifices he has made, and Akainu's magma punch is meant for him and the reason why he's gotten 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 claims to still not like getting shot. Ostensibly he gets 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 his idea of a hero is a completely selfless person (in his own words "A hero shares the meat, and I want all the meat"), and prefers being a pirate so he can have more freedom.
  • Improbable Age: While this applies to most of the 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 he's 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 intends 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: Due to his naivete, he has said something offensive or uncofortable towards basically everyone he has met 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. With Gear Fourth, he can use Armament Haki on his body without losing flexibility.
  • Ironic Hell: Inverted: Luffy ends 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 her 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 refuses to give in until a person he's trying to recruit joins his crew, he finds himself, after refusing multiple times, 5640 followers who become part of his grand fleet without his approval.
  • I Thought It Was Forbidden: Even though Gear Second 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 Gear Second is 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!
  • Jerkass Façade: He pulls this sometimes to help his friends, like when he says he's not Coby's friend and forces the latter to hit him. Allowing Coby to join the marine.
  • 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 wishes it's something more (and still interprets his acts of kindness as reciprocating her feelings).
  • Kiai: At the end of his fight with Rob Lucci, he hits him with a powerul Jet Gatling, screaming at every punch.
  • 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 Enel and his priests. During his fight with Katakuri, he even learn how to foresee some bits of the immediate future! 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 and anyone nice to him, 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, despite facing enemy presumed to be undefeatable for him; 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.
    • He does this while escaping from Impel Down, as he realizes he cannot defeat Magellan. However, this is also because he has not time to lose and has to go and rescue Ace as soon as possible.
    • Does again versus Katakuri. When you exhaust literally every option at your disposal and only manage to gain a temporary advantage that you've 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, especially before the beginning of a fight.

    L-R 
  • Leeroy Jenkins: Does this whenever he's NOT trapped somewhere and can't fight, but the most notable straight example is at the beginning of the assault on Enies Lobby, where he actually take 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 results in the stove exploding since he forgets to turn it off. What he cooks is 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 can stomach. And he messes up so often while making it that he blows the entire group's week's worth of food in one go. This incident has the purpose to show how important Sanji is to the crew.
  • 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 muscles with so much air, he can't even stand still due to the bounciness. Even his opponent calls it ridiculous. Until he gets 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. With Gear Second, he becomes even faster and withGear Fourth, his speed, durability and strenght get turned Up to Eleven, but only for ten minutes.
  • 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. Ivankov, a close ally of Dragon, comments that Luffy strongly resembles his father.
  • Living Emotional Crutch:
    • Luffy is this to Ace, to the point that he says that he probably wouldn't want to live if it isn'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. This also happens during the end of the most intense arc, where he exausts all of his energies in the fight and needs his crewmates to save him.
  • 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 has made him completely unaware of the major events taking place, some of which even involves 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 leads to Marco's disappearance and Blackbeard's ascension to Emperor status. One wonders if Rayleigh has intentionally prevented such news from reaching him (especially the truth about Kuma and his agenda). Even Jimbei remarks on how harsh it was for Rayleigh to not tell Luffy about these things.
  • Magnetic Hero: In every arc, due to his nice nature and personality, he manages to make many allies and friends. 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, but is reconstructed at the end of the arc, where many of Corrida Coliseum warriors and their crews, ask to sail under Luffy and the Straw Hat Pirate flag, and becomes his Grand Fleet. 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. This trait is lampshaded by Mihawk after noticing all the allies that helps him during the Summit War:
"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!"
  • 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 electricity powers who claimes to be an actual god. His Devil Fruit is so powerful that anyone considers him invincible, but Luffy's rubber-like body is capable of negating Enel's Goro-Goro-no-Mi powers completely, resulting in Enel being shocekd beyond belief.
  • 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 Poundman 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 meets her, Hancock's surrogate mother Nyon is worried that she has become as cold as she appears, but fortunately, Luffy's interactions with her proves that this isn't the case, and brings up Hancock's better qualities.
  • Multiform Balance:
    • Normal Luffy is a Jack-of-All-Stats (still a Lightning Bruiser compared to most people), as he is fast, strong and has an high endurance.
    • Gear Second turns him more into a Fragile Speedster. He's faster and hits harder, but his endurance stays the same.
    • Gear Third 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.
    • Gear Fourth - 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.
    • Gear Fourth - 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.
    • Gear Fourth - 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, since it's a gift from Shanks.
  • My Greatest Failure: Not being able to save his brother Ace from being sentenced during the Paramount War. It brings into a long Heroic B.S.O.D., until he snaps out of it and 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 and he learns new creative ways to use the Gum-Gum Fruit:
    • In the Enies Lobby arc, he reveals two new fighting techniques called Gears, with Gear Second making him a Fragile Speedster by pumping his blood at a much faster rate and Gear Third which consits in him pumping hair in his bones, inflating any body part for a stronger, but slower, attack.
    • During the Time Skip, he learns to utilize the three forms of Haki, especially Emperor's Haki.
    • While fighting Donquixote Doflamingo, he unveils the Gear Fourth which is essentially a Super Mode that makes him a Lightning Bruiser. As the other two forms of Gear Fourth are revealed, it's revealed they're essentially upgraded versions of his Gear Second and Gear Third combined.
  • Nice Guy: He's usually friendly, cheerful, and amiable and will do anything for his friends. 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 it seems to be the same hat Gold Roger himself wore when he started his journey.
  • The Nicknamer: Luffy has a habit of giving child-like nicknames to those he meets on his journey, and he tends to call them this way even when they say they don't like it.
  • Nigh Invulnerable: His latest Super Mode, Gear Fourth, jacks up his Lightning Bruiser to the extreme, but most notably his durability.
  • 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 just because he lacks any ability besides fighting, 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. However, when he makes a decision, as stupid and dangerous it can be, his crewmates follow it.
  • 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. This is why he prevents Silvers Raylegh to tell them where the One Piece is, and scolds Usopp for having asked it.
  • 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 him several favours.
  • No-Holds-Barred Beatdown:
    • He's usually subjected to these during the first match against the current Arc Villain, but after he learns his enemies' strengths and weaknesses, he manages to win in subsequent rounds.
    • After two years of training, he's been handing them out with impunity to the first enemies he faces in the new world, beating the crap out of Hody Jones with only one major wound (and Jones only manages to land it because Luffy is underwater, has his movements restrained by a bubble, and is trying to prevent a falling mastodontic arc from destroying Fishman Island). Caesar Clown similarly gets his ass kicked without even managing to land a single hit on Luffy, although not after knocking Luffy out the first time they clashes.
    • With the reveal of Gear Fourth, he delivers one of these to Doflamingo, who can barely defend himself.
  • Nonchalant Dodge:
    • Right after coming back from two years of training, just to show how fast he has become, he dodges a lightspeed beam by simply twisting his head.
    • During a sumo match with Urashima, the latter tries to hit Luffy with multiple sumo techniques, but Luffy dodges every single one of them without putting forth any effort.
  • Normal Fish in a Tiny Pond: Inverted; like Zoro and Sanji, he's a Big Fish in a Tiny Pond in the East Blue. This is no more true in Paradise, the first half of the grand line, where he faces enemies able to push him to his limits. Come the Marineford Saga though, Luffy gets a taste of New World-level threats and it becomes clear that he's nowhere near as strong as he thinks he is. Cue a mental breakdown, recovery, and two years of training in an effort to catch up to the real big fishes.
  • 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's impaled clear through his torso by Crocodile's giant hook hand; a bit of time to rest later and he's ready to fight him again.
  • No-Sell: Being made of rubber, blunt force attacks can't do anything to him (unless it's imbued with Armament Haki or from Nami or his grandfather) and is immune to electric attacks, no matter how many millions of volts it is. After his fight with Magellan, he's also become immune to some, but not all, poisons. Gear Fourth - Pound Man allows him to No-Sell Haki-imbued blunt attacks because he combines his normal body's elasticity and the Armament Haki, and Gear Fourth - Tankman allows him to No-Sell Haki-imbued piercing attacks.
  • No Sense of Direction: Not as terrible as Zoro's, but it's still really bad and gets lost more often than not.
  • No Sense of Personal Space: Due to his naive and cheerful personality, Luffy's is fond of hugging and being close to anyone he considers "friend", without worrying about the latter's reaction. Like when he gives a genuine and loving hug of frienship and gratitude to Hancock,too bad he does not realize that it means a lot more to the poor woman.
  • No Shirt, Long Jacket: Post-Time Skip, Luffy replaces his vest with an open-button jacket which leaves the X-shaped scar on his chest visible.
  • 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, after seeing how close Luffy is to meeting his own end on the same scaffold before his miraculous survival, make 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. Justified since he's made of rubber, and no blunt-attack, unless its really strong, can hurt him.
  • No True Scotsman: A pirate variant. He 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. Subverted after the time-skip, during he learns how she feels and even assumes that when Hancock says she has a request, that it's a proposal and he preemptively declines it. 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 is being held in a government facility he charged head on into it, well ahead of his crew. The enemies numbered in the thousands. Luffy cuts through them in mere minutes. This is turned Up to Eleven after becoming even stronger during the timeskip, as he knocks out fifty-thousand fishmen with his Emperor's Haki alone!
  • 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", those who knows him only by fame or are his opponents, will likely refer to him with the latter.
  • 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 is 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.
    • When his entire crew is fighting against Kizaru), he orders to retreat. For an Idiot Hero who has always fought against the enemy, no matter how bad the odds were, this is pretty significant.
    • 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.
  • Outside-Context Problem:
    • At the beginning of his pirate career in East Blue, he's 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, come along able to deflect bullets and absorb blunt blows without taking any damage, most of his early enemies don't know what to do except for Buggy and Arlong, both who have sailed the Grand Line where Devil Fruit users are more common. Buggy also have the extra benefice of being a Devil Fruit users himself.
    • Luffy does it again during his battle against Eneru. Before Eneru meets Luffy, he believes to be completely unbeatable and most of his fights ends in a curb stomp in his favour. That is because Eneru has the Rumble Rumble Fruit that turns 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 too. Eneru literally has no clue that a foe like Luffy could exist and the face he makes when he realizes that Luffy isn't affected by his powers is priceless.
  • Papa Wolf: Try to hurt a member of his crew – or for that matter, one of your own subordinates – and you are in for a complete beatdown.
  • 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 works in his favor as it's more than enough to fool Doflamingo and Diamante when he switches 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: even before he discovers Haki or his Gear abilities, Luffy deals some pretty amazing feats of damage. And it goes on from there as he gets stronger and stronger. With two uses of Gear Third, he destroys the top half of the Tower of Justice (the first has made the Tower shake a little...and that is just by knocking a massive steel door down). After two years of training, he becomes strong enough to destroy the massive ship Noah by using a haki-strengthened Gear Third gatling, the only reasons he doesn't completely destroy it is because the Sea Kings stops Noah from colliding with Fishman Island before he could finish the job. And finally we have his new form, Gear Fourth, which can split an entire city into two slabs and forced them upwards into the air with a single strong attack. 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 of 15' and more! 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). During the tournament at Dressrosa, he completely knocks an actual giant (which is about 70 feet tall) 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. Though he does cause lots of property damage, doesn't care about the laws and he's not opposed to stealing available loot if an opportunity arises. Then there is that prison break...
  • Plot Armor: Many times, he manages to survive and achieve things when the odds are completely against him. Lampshaded by Basil Hawkins when tries several times to calculate a scenario which Luffy can't possibly survive, but Luffy always has at least a slim chance. This is justified by having the Will of D., which means he's destined to change the world.
  • 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 appeares 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.
  • Power Makes Your Hair Grow: Snake Man, the third Gear 4th form Luffy introduced, visibly make his hair longer than usual.
  • The Power of Friendship: He always believes in his crew, even when they appear to betray or murder one of their own, and when his friends are in danger, nothing will stop him. During his fight with Lucci, what gives Luffy the strength to stand and defeat Lucci, is Usopp that tells him to not give up.
  • 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 and/or his friends. 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 (like Buggy and Mr 3). 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, moves to protect Luffy's crew).
  • Power Perversion Potential: Yes, everything stretches, as the inhabitants of Amazon Lily have discovered. Of course, being Luffy, he never make any use of this.
  • 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.
    • However, in nearly every arc, he changes his vest with another one of different color.
  • The Promise:
    • At the beginning of the series, he makes one with Shanks, that he'd return his Straw Hat to him one day after he has become a great pirate, and is what motivates him to start his journey. It is for this promise Shanks refuses to see the injured Luffy at Marineford, as Luffy hadn't reached that level yet.
    • He made another 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's only able to keep the former, and he admits there's 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 hasn't left Luffy alone in this world — Sabo still lives, and has made a promise to himself to inherit Ace's will and protect Luffy at any cost.
  • The Protagonist: He's the central or focal character in One Piece.
  • Punched Across the Room: Given the strengths of his attacks, this happen quite often to his enemies, especially when he uses the Gom Gom Bazooka and its variations.
    • A notable example is Ceasar Clown who, after getting hit by the Grizzly Magnum, he's sent flying through different rooms reaching the end of his vast laboratory.
    • And a particularly effective one against Doflamingo, where he sends the Warlord to the other side of Dressrosa after showing off his Gear Fourth for the first time.
  • Raised by Grandparents: He was looked after by his grandfather during his youth, although, since Garp is often busy with his job as marine, he spent more time with his foster mother Dadan.
  • Rapid-Fire Fisticuffs: His Gom Gom Gatling technique and its variations consist in a series of punches to his enemies. They're often used to finish his main opponent once and for all or to get rid of hordes of weak enemies.
  • Real Men Eat Meat: Meat is his favourite food, to the point he's often seen eating a large chunk of meat, and he's a strong and tough pirate.
  • Red Baron: "Straw Hats" from his Iconic Item. After the events of Whole Cake Island, he's also known as "The Fifth Emperor".
  • Red Is Heroic: Luffy's main color scheme is red and he's, for the most part, an heroic person willing to do anything for his friend.
  • Red Oni, Blue Oni: Since he's a hyperactive keet always ready to have an adventure, he's generally the Red Oni to any other, like his crewmates or his allies (like Law), who are more often than not calm and clever compared to him.
  • 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, which simply turned his body into rubber. This element is Discussed during his fight with Rob Lucci, who notes that Gear Second is a technique made by and only for a Rubber Man like him, 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 stretch and inflate 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, saying that he can't use swords, navigate, cook or lie.
  • 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.
  • Secret Keeper: He accidentally discovers Boa Hancock's "Hoof of the Rising Dragon" tatto on her back and later learns of the Gorgon Sisters' secret past as slaves, but doesn't reveal it to anyone and even prevents the Kuja from seeing it in one occasion.
  • 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, both being the protagonists of the most sold and arguably the most popular manga series.
  • Shared Family Quirks: Even before Garp is revealed as Luffy's grandfather, they both show 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 learns Haki, Luffy himself is guilty of this a few times. He has the tendency to charge headfirst into fights with Logia users even after it's clear he cannot 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 earns the record-breaking bounty of 30 million berries for a rookie in East Blue where he win all his fights. Smoker being an exception to the rule. And the East Blue Saga covers a hundred manga chapters! Even in the early parts of his adventure in the Grand Line, Luffy’s win record continues and it seems like nothing can stop him until he reaches his goal. But then, from the Sabaody arc to the Summit War, it's subverted. Repeatedly. And hard.
    • A more downplayed version appears post-Time Skip. Every fight Luffy has for the first three arcs are complete curb-stomp battles with him on the giving end, and he literally does not have a serious fight until the Dressrosa arc, and it's against an old, legendary pirate who used to fight with Garo 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, is long past his prime as he later admits, and that Luffy takes on Doflamingo with the help of Trafalgar Law, and it's still his toughest fight to the moment until he engages Gear Fourth. After that he has 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 different Gears versions now since he's facing stronger enemies.
  • 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 doesn't know he even has a father until Garp, his grandfather, tells him at the age of seventeen. He als 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 one of the greatest version of this trope. Whenever he visit a new island, he always happen to stumble across the current Arc Villain's plan, usually just in time to ruin it before it's completed. It should be noted that, more often than not, he never even goes in intending to stop the villain or knowing the villain even has an evil plan. He is literally just an unexpected variable that happened to mess up the scheme because the villain does just ONE thing wrong. That thing is usually trying to preemptively eliminate him.
    • Reversed with Blackbeard's master plan. Everything Luffy does just work in favor of Blackbeard's plans, even speeding them up significantly, the most obvious example being the Impel Down incident.
    • Doflamingo attempts to take advantage of these tendencies in order to screw up Law's plan. He correctly deduces that Luffy would immediately be sidetracked by a tournament to win the Flame-Flame Fruit, most likely to ensure that his brother's power does not end up in the wrong hands. It would've worked, but it backfires magnificently when it creates 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 is most likely the main reason Sabo is 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 Rufy 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. After his fight with Katakuri, he masters it to the point of foreseeing small gilmpses of the future.
  • Stock Shōnen 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 fails him is during the Marineford arc, which is 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, more often than not, the only one who has a chance against said opponent.
  • Straight Man and Wise Guy: He's basically the wise guy for everyone else's straight man, due to his impulsive and naive personality. More commonly, he's the wise guy for the entire crew's straight man (especially Nami or Usopp). In his recent alliance with the Heart Pirates, he's 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.
  • Strange Minds Think Alike: He and Zoro, despite having very different personalities, are both really quirky and share similar thoughts, for example: after Luffy's explanation on the difference between pirates and heroes – heroes share meat, pirates don't – which Zoro is not there to hear, Zoro gives an incredibly similar analogy, except he substitutes booze for meat. Another istance is 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 intends 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 for reasons you can easily guess. 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. He later falls for Caesar's disguise despite having recognized him a few moments before. The only aversion is Pekom's far too obvious one.
  • Super Mode: He has a few of these techniques, which he dubs "Gears", that makes him much stronger;
    • Gear Second 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.
    • Gear Third 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 have been minimized; now he can keep the air insides his bones in only the places where he needs it, making him more flexible.
    • It should be noted that Gear Second and Third can be combined to become much stronger, but doing so leaves him exhausted after a short use.
    • "Gear Fourth, Poundman" is activated by [[spoiler: 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 has 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]].
    • "Gear Fourth, Snakeman", is a variation of Poundman that is less durable but much faster. It specializes in very fast punches that can change direction, so they can hit the target even after the latter has dodged them. It's fast enough to hit Katakuri, who has Combat Clairvoyance.
  • Super Reflexes: Like many characters, he has them and developed them through sheer training, especially thanks to Observation Haki. The latter becomes advanced enough to become Combat Clairvoyance.
  • Super Toughness:
    • His rubber body nullifies all but the most powerful blunt blows (though Haki-imbued attacks strike him as if he were normal). 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.
    • One of the best examples is what he endures facing Crocodile]. Three. Times. He's stabbed with a giant hook, drained of all the fluid in his body, poisoned, cut by Crocodile's extremely sharp [[DishingOutDirt sand, and physically beaten all over the course of 24 hours; yet he survives with just some bruises and cuts (although, without some external help, he would've died after the first match).
    • 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 includes 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 taken 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 are 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 notice 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 is the one to ruined her candy factory and ate all her candy, he earns her rage, which would have gone to destroying Fishman Island. It's a lie and Big Mom suspects as much but won't try to disprove him and instead accept his challenge.
  • Tastes Like Friendship: Although his friendship with them grows for different reasons over time, it only takes Nami and Rebecca some food for him to instantly start to like them, pretty reasonable for a simple-minded Big Eater. The latter case is lampshaded when Law expresses annoyance that Luffy's fighting for Rebecca's sake because she just gave him food. It happens again in the Wano Arc when Tama offers him food.
  • Tears of Joy: Can only burst into tears when, in chapter 731, Sabo reveals he is alive. He's really that happy and suprised to learn he still has one brother.
  • 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: In a nutshell, Luffy can't paint.
    • His attempt to paint his Jolly Roger on the Going Merry isn't very succesful and the rest of the crew hates it so much they have Usopp paint over it, even his logo painted on Laboon looks just as bad.
    • After Foxy loses his Jolly Roger, Luffy is nice enough to paint him a new one, and Foxy is happy of this... until he sees the result.
    • Even his drawing of what the crew's shipwright should look like is so bad it freaks out both Usopp and Sanji.
  • Thanks for the Mammary:
    • Luffy accidentally gropes Boa Hancock when he's hiding under her dress since how he's latched onto her keeps her from walking straight. The act certainly affects Hancock, but she's 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 realizeds it, he thought that he's standing on a giant pudding and bounces on it.
  • Third Time's the Charm: Against Crocodile, though there is a case to be had in his confrontations with Eneru and Rob Lucci. It also takes him four separate rounds with Doflamingo before he finally beats him, though in these case it's not Doflamingo that defeats him but simply finds a way to keep Luffy busy.
  • 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 gets 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. Still, he ultimately leaves before the fight could end with a winner..
    • 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 with her help.
  • To Be a Master: His dream is to become King of the Pirates, which means he has to become the strongest pirate.
  • 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, sometimes, his choices put even his companions in danger.
  • Took a Level in Badass: BIG TIME during the Time Skip. To the point that he doesn't have a real challenging fight since the Time Skip until the Dressrosa arc.
  • Top-Heavy Guy: When he activates his Gear Fourth, his upper body gest much larger, while the lower half remains small. 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. He's been once put in a sleep that should have lasted for three days but he's woken up when Usopp yells there is meat. He loves it 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, and were done by his grandparent, with the genuine intentons to help.
    • To get as much strong as possible in the span of two years, he's trained by Silvers Raylegh on an island inhabited by giant and dangerous animals.
  • Trauma Conga Line: The Paramount War is one huge Break the Cutie moment for our hero, starts during the Sabaody arc, where all his True Companions are scattered, then gets many times worse in Impel Down and Marineford: 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 and easy way to get Luffy to be your best friend. Just ask Rebecca or Tama.
  • 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. Of course, he decides to become a pirate instead of a Marine.
  • 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 gets him ridiculed and beaten, but he still stands strong by his beliefs.
  • Undying Loyalty: Luffy not only earns this from his friends he freely gives it as well. Nothing will stop him from helping his friends achive their dreams. He will protect them with his last breath or even declare war to the entire World Government if needed.
  • 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 properly use its forms. This is also what many tell him In-Universe during the Marineford Saga in regards to his abilities in general. His physical power and natural talent for combat is quite impressive, but... a combination of not having any sort of hardening or observation Haki at all, no knowledge of when they are being used against him, fighting against people even stronger and faster than he is, and most importantly, fighting against people who can actually negate his strongest attacks (such as Magellan) for the first time lead to a long line of defeats. Thankfully, he's gotten better and is now Strong and Skilled.
  • Unstoppable Rage: He switches into this mode fairly frequently at the climax of his battles every arc, and he's really unstoppable. On Enies Lobby, the soldiers are literally being sent flying by the hundreds from the moment Luffy got there, and it osn't over until 3000 have been defeated and he has made his point — shit os getting serious.
  • Victory by Endurance:
    • How he wins the fight against Rob Lucci, as Luffy pushes himself to his absolute limit to knock Lucci out with one final attack when they're both already exhausted.
    • 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.
    • His duel with Katakuri. While Katakuri is faster, stronger, more skilled, and overall the better combatant, if there is one thing Luffy is better than him at, it's taking hits. Luffy takes advantage of that, dodging and tanking Katakuri's hits until his Observation Haki advances far enough for him to start countering and even attacking back. Finally, after over ten hours of fighting, the battle ends 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: Sometimes his clothes takes much more damage than him.
  • "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...: As he self-admits, he can only give punches, and 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-shots 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 inflicts one continuous Worf Effect on Luffy; from Boa Hancock smashing Pacifistas effortlessly (while Luffy needs his whole crew to barely beat one) to Smoker no selling the Jet Gatling Gun (which is his strongest Gear 2nd move at the time), the entirety of the saga mocks the notion that Luffy is any kind of threat to the top tier powers in the New World. Cue two years of training to catch up, and he effortlessy dodge a lightspeed beam and defeat a Pacifista with. A. Single. Punch.
    • 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 has 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 are perhaps his two toughest opponents yet at that point. Doflamingo, in particular, is 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 isn't pushed back an inch from where she stands. 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, which has become among the world's most infamous pirate crews, and has accomplished several feats using a lateral or outright insane branch of logic.
  • 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 finds the resolve to keep on living is 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:
    • He's one to Smoker. This has become especially apparent when Smoker is 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 is stuck in Tashigi's body Luffy refuses to fight him until he's at full strength.
    • Charlotte Katakuri. Unlike a lot of Luffy's foes, Luffy make no move to insult him and instead purely bases his judgement on Katakuri's abilities as an opponent. This is even after Katakuri's physical and personality flaws are 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's 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: To Luffy gender makes no difference, and he has faced and punched multiple women. Examples include Alvida, Ms. Valentine's Day, Vivi (as Ms. Wednesday and later a slap in a Get a Hold of Yourself, Man! moment), 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 has an X-shaped scar across his chest as a gift from Akainu's attack at Marineford.
  • You Are Not Ready: This is the reason Kuma scatters the crew to different islands, so that they can train and become strong enough to face the New World, but it's not clear at first. 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 gets up and kicks Lucci's ass. Doesn't work against Magellan, however...
  • You Never Asked: The main reason why nobody knows that Luffy and Ace are not blood related is because nobody bothered to ask.
  • You Remind Me of X: Luffy frequently reminds others of Gol D. Roger, including Railegh, Roger's number two. The most clear example is 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. This latter similarity is noted by Smoker, and induces him to follow and capture Straw Hat.
  • 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.
