->''"Anyone inside Law's sphere is a helpless patient on his operating table!! This is his operating room! Inside this space, he reigns supreme and operates at will!"''
-->-- '''Smoker explaining Trafalgar Law's Devil Fruit ability (Chapter 661)'''

Trafalgar Law is the captain of the [[Characters/OnePieceSupernovasCrews Heart Pirates]] and one of the eleven pirates dubbed with the moniker "[[Characters/OnePieceElevenSupernovas Supernova]]". He's a very laid-back person, and while his speech is very polite, he has no problem with taking mocking jabs at people or giving them the middle finger. Law has eaten the Op-Op Fruit (''Ope Ope no Mi''), which allows him to create a spherical area wherein he can freely manipulate the objects inside, be it splitting them apart without permanently damaging them, levitating things into the air and moving them like telekinesis, or teleporting objects around. He gladly accepts new people to join his crew, and is also careful to deny any undeserved credit, though he does not like being ordered around at all.

Over the TimeSkip, he's become one of the [[Characters/OnePieceSevenWarlordsOfTheSea Seven Warlords of the Sea]], a feat he seems to have achieved by handing over 100 pirates' hearts to the Government. It is also revealed that he was the only survivor of the North Blue country Flevance and a member of the Donquixote Family. After an encounter in Punk Hazard, Law forms an alliance with the Straw Hat Pirates, an act that revokes his status as a Warlord, to take down Kaido. However, his main target is Kaido's ally "Joker", AKA Donquixote Doflamingo, whom he holds in contempt for the death of Corazon. Despite many grueling battles, the alliance manages to defeat Doflamingo in Dressrosa.

He currently has a bounty of 500,000,000 Berries.[[note]]His first known bounty was 200,000,000 berries. During the TimeSkip, it rose to 440,000,000 million berries before being frozen as a Warlord. After the events of Dressrosa, his bounty was reinstated and rose to 500,000,000 berries, the second highest among the Supernovas (behind Luffy).[[/note]]

[[folder:# - C]]
* TwentyBearAsses: Law gained the position of Warlord of the Sea by extracting 100 pirates' hearts and sending them to Marine HQ.
* AdaptationDyeJob: He has yellow eyes and dark blue hair in the manga, but black hair and gray eyes in the anime. His BadassLongcoat in the Dressrosa arc is also changed from black in the manga to brown in the anime.
* AffectionateNickname: Luffy originally just calls Law "Traffy" (or Torao in Japanese) because he can't pronounce his surname to save his life, but the nickname gradually morphs into an official nickname as the series progresses and they become close allies.
* AlwaysSomeoneBetter:
** While he's much more intelligent than Luffy, Law lacks the latter's charisma due to his overall gloomy nature and pragmatic tendencies. At times, characters who wave away Law's ideas will warm up to them almost immediately when Luffy proposes something similar or even if he requests that they simply listen to Law.
** This also applies to combat. While Law's powers are more versatile and esoteric than Luffy's, Luffy outdoes him in sheer power, as seen with their respective fights with Doflamingo. Whereas Law is able to match Doflamingo enough to give him a decent fight, Luffy flat-out dominates him, and the only reason he didn't finish Doflamingo off in the first burst is because he briefly ran out of energy.
* AmbiguouslyEvil: Certainly more morally grey than any of the Straw Hats, and guilty of a lot of OffstageVillainy; however, since he's a [[WildCard rather mysterious and unpredictable character]], it's unclear exactly how much of his nasty reputation is actually deserved, seeing how the Straw Hats appear much worse than they really are to the eyes of the world. The Dressrosa arc clears up some of the mystery surrounding him; though he is certainly cold, distant, and cruel, he doesn't appear to be truly evil, since he obviously has standards, seems to care about his crew, and goes out of his way to help his Straw Hat allies on multiple occasions.
* AndShowItToYou: His "Mes" technique allow him to remove the heart from a person body. Due to the Ope-Ope Fruit, this operation isn't lethal, but the removed heart is very vulnerable and, if the stabbed, the owner dies.
* AnimalMotifs: The spotted seal, as suggested in SBS volume 76. This goes with his spot-patterned attire and following his crew's Arctic animals theme.
** In SBS volume 95 Oda lists him as the snow leopard.
* AntiHero: Despite the fact that Law has some similarities with ''a lot'' of the Straw Hats' enemies -- he's a cold, cruel, and sadistic man who finds pleasure in torturing others and sowing chaos in the world -- he nonetheless has a neutral alignment (relative to the Straw Hats) at worst and, as their ally, has been on the side of "good" since the timeskip, has standards and morals, is pretty decent towards his allies, and deeply loves his crew, his biological family, and [[MoralityPet Corazon.]] Furthermore, while Law certainly has a noble goal in wanting to avenge [[ParentalSubstitute Corazon]], the methods he uses -- and is willing to use -- to achieve it are pretty reprehensible: being willing to leave behind sick children who were poisoned [[LackOfEmpathy despite the fact that he suffered the exact same fate as a child]] and only saving them as a favor to the Straw Hats (or so it seemed); sending 100 still-beating pirate hearts to the World Government, allowing the government to kill them or hold their lives in their literal hands (though, admittedly, it is possible that these pirates were AssholeVictims, but it's still pretty disturbing); being prepared to possibly sacrifice the lives of thousands of innocent Dressrosan civilians by having a plan in which Kaido would rampage through the island to kill Doflamingo; and stating that he was willing to destroy the whole world if it meant he could achieve Corazon's wish.
* ArcSymbol: The HeartSymbol appears a lot on things pertaining to him. Such as the heart tattoo on his shoulders and back (which apparently [[spoiler:the citizens of Flevance also had]]), him being appointed as the Heart Seat of Doflamingo's "card suit" top officers and being a former subordinate to a deceased Heart Seat member, the Op-Op Fruit being heart-shaped, and when he used his powers to switch two people's "souls", they're represented by a heart shape. Oh, and he can tear out actual hearts as well.
* AnArmAndALeg: [[spoiler:Doflamingo cuts Law's right arm off with strings. Only temporary, as it is reattached and healed later by Leo and Mansherry.]]
* ArmorPiercingAttack: His Gamma Knife, a laser blade made of energy, penetrates through an opponent's skin and deals major damage to their innards, leaving no external wounds at all. [[spoiler:And as Kaido can attest to, not even his dragon form's incredibly tough skin and scales can do anything to block the attack.]]
* AscendedExtra: He ranked in the top 10 in ''One Piece's'' official popularity poll after his first appearance. It's no coincidence that he's gotten more screen time since, becoming an important ally after the time skip in the same vein as Vivi during the Alabasta saga. He was ranked the 2nd most popular character in the series after Luffy from a poll taken in late 2014, beating Zoro who was consistently 2nd before. Law was already a major character by that point, but him beating so many established veterans is very impressive.
* AuthorityEqualsAsskicking: When he's a Warlord, he beats '''Smoker''' in a one-on-one fight, a feat that not even Luffy has managed (though admittedly one he probably ''could'' now). On a more general note, he's the captain of the Heart Pirates and seems to exercise his authority in the role more than Luffy does; he is also almost certainly the strongest member. The Dressrosa Arc reveals [[spoiler: he was taken in as a child by Doflamingo to become his future right-hand man and the third holder of the title of ''Corazon'']]. As a result, in his youth Law receives rigorous training and an extensive education [[spoiler: in order to prepare him for his future role as the NumberTwo of the Donquixote Family. Following his defection, he uses the skills he was taught against his former crew and kills the first 'Corazon' Vergo during the events at Punk Hazard, lands a devastating blow to Trebol that leads to his defeat, and even manages to deal near-fatal damage to [[BigBad Doflamingo]], all while gravely incapacitated.]]
* AwesomeMcCoolname: When you're named after a historical battle, this is inevitable. [[spoiler:His full name gives him another historical battle.]]
* AwesomenessByAnalysis: Law is shown to have figured out [[spoiler:Hawkins's voodoo]] ability after seeing it in action all of once, without the need of any explanation but just by noticing some details. He immediately takes out the man's subordinates before pressing the attack and forcing [[spoiler:Hawkins to defend since he no longer has any subordinates to pass his injuries to.]]
* BadassInDistress: Law and Doflamingo have a personal connection, and when the former goes to Dressrosa with the Straw Hats, he becomes Doflamingo's main target. During the Dressrosa arc, Law gets[[spoiler: shot, captured, rendered unconscious, chained up, and has his right arm sliced off by Doflamingo.]]
* BadassLongcoat: During the Punk Hazard arc, Law wears a long coat, then changes it with a different one in Dressrosa. He gets yet another one for the raid on Onigashima in Wano.
* BeatStillMyHeart: Using his power, he can literally remove your still-beating heart, and you'll live through it, because his power makes it a non-fatal wound. He does this to Smoker in order to beat him. It's implied this is also what happened to the 100 pirates Law used as a way to enter the Warlord position.
* BenevolentBoss: His crew genuinely seems to like him, and are very happy when Luffy is able to tell them he's okay. Law also made sure to keep them out of the way for the Punk Hazard and Dressrosa arcs. An SBS later reveals that he's known at least the core members (Bepo, Shachi, and Penguin) since they were teenagers (or a kid in Bepo's case), so it's likely their relationship is deeper than just boss and subordinate.
* BestServedCold: His plan of revenge against Doflamingo is one of big proportions, which includes him becoming a Warlord, allying with Luffy, and even a gambit that involves making Kaido angry at Doffy, and apparently has been done for about 13 years.
* BewareTheNiceOnes: Despite being a near PerpetualSmiler and having a really laid-back personality, he has a really nasty reputation amongst his fellow Supernovas. How bad, you might ask? To join the Seven Warlords of the Sea, he extracted and delivered 100 pirate hearts to the World Government. Though [[CharacterizationMarchesOn he's established post-timeskip to be more of a]] JerkWithAHeartOfGold than outright nice.
* {{BFS}}: Carries a sword almost as tall as he is. Its name is Kikoku (鬼哭, lit. Demon Wail), and its size is justified since it's a nodachi.
* BigBrotherInstinct: When Law was offered a (false) way out of Flevance, he refused to leave with the other children because his little sister Lami was still sick in the hospital.
* BigDamnHeroes:
** Pops up in the middle of a three-way (technically four-way) war between the Blackbeard pirates, Whitebeard pirates, and Luffy's motley gang of Impel Down escapees, and the Marines and Seven Warlords of the Sea to rescue Luffy. That takes balls.
** Later, he shows up in the middle of Luffy and Franky's fight with the Yeti Cool Brothers to take down the remaining brother before he could leave with Nami again.
** He apparently did this in the past to help out Bepo, beating up two delinquents who were bullying him. Bepo and the delinquents in question -- [[DefeatMeansFriendship Shachi and Penguin]] -- were so impressed by Law that they decided to join him on his travels and, eventually, they formed the Heart Pirates together.
* BilingualBonus: More of a bilingual hand gesture, but in Spanish, the middle finger is called "(el dedo del) corazón". So yes, there really is a hidden meaning behind it.
* BreakoutCharacter: Law shot up high in the Character Polls [[note]]Higher than even some of the Straw Hat characters even.[[/note]] before he really ever did anything. Not coincidentally, he's gone on to become a major supporting character in the series; pulling a BigDamnHero during the Summit War Saga to save Luffy when the rest of his crew was PutOnABus, and even getting upgraded to {{Deuteragonist}} during the Punk Hazard and Dressrosa arcs. By the time the Dressrosa saga was over Law managed to reach ''second place'' in the latest Character Poll, being the only character besides Luffy who has ever managed to rank higher than Zoro.
* BrokenPedestal: As a child, he admired and wanted to become like Doflamingo, until he bonded with Corazon as they searched for a cure for Law's Amber Lead Disease, with which they only succeeded at the cost of severe injury to Corazon. The final straw was Doflamingo murdering Corazon while claiming that Law's only importance, now that he'd eaten the Op-Op Fruit, was to die so Doflamingo could become immortal; after that, the pedestal broke so badly that Doflamingo went from Law's idol to his greatest enemy.
* BrutalHonesty: Law's ''very'' blunt whenever he expresses his thoughts and opinions to others.
* BuriedInAPileOfCorpses: What he resorted to in order to escape his hometown when it was attacked. He provides the page image.
* ButtMonkey: Ever since he allied himself with Luffy, Law has been forcibly dragged into the Straw Hats' hijinks, and more-or-less subjected to Luffy's numerous whims. His life in general ever since the Pirate Alliance saga started has been one long-running joke.
* ByronicHero: Law is a [[MrFanservice particularly attractive]] character in the ''One Piece'' world, with more distinguished facial features like Shanks and Robin. He boasts enough charisma to gather a crew with 20 members. He is intelligent and cunning, having devised a plan for over 13 years to bring down Doflamingo's empire and hamper an Emperor's plan to increase his power. He has experienced two great losses in his life: first his family, friends, and homeland of Flevance, then the father-figure to whom he owes his life. Eventually, everything adds up to him being able to avenge his fallen hero ([[TrueCompanions with Luffy's help]]) and also have enough determination go on living afterwards.
* CelibateHero: Law is one of the few people in the world to have virtually no reaction to Boa Hancock's beauty, and unlike his crew, he also doesn't comment on the abundance of attractive women in [[LadyLand Amazon Lily]]. In general, he seems more annoyed by matters of romance than anything; when Monet tries to playfully flirt with him, he just coldly ignores her, prompting her to comment on how "unsociable" he is.
* CharacterizationMarchesOn: Was introduced as a laid-back but powerful pirate who really only showed his mean side when angered and was a PerpetualSmiler the rest of the time. After the timeskip, he was portrayed as [[TheComicallySerious much more serious]] and [[PerpetualFrowner smiled much less often]], in addition to his ability for cruelty being a little more apparent. To be fair, he was engaged with the difficult task of defeating Doflamingo at the time and has had to consistently deal with the Straw Hats' wacky hijinks.
* ChekhovsGun: He got his right arm severed by Doflamingo. [[spoiler:Later, he uses that severed arm (with it holding his sword) for a surprise attack on Trebol.]]
* TheChessmaster:
** Comes off as this more-and-more as the series goes on, particularly in the Punk Hazard arc, where he proposes an alliance with Luffy in order to take down an Emperor, starting with blackmailing Doflamingo.
** By the time Law has arrived in Wano, he has gotten so used to Luffy's antics, that in Chapter 977 he [[spoiler:(correctly) [[BatmanGambit expects]] Luffy to [[LeeroyJenkins recklessly charge into the fray]] and has incorporated this factor into his plans to assault Kaido and Orochi's palace.]]
* ClosetGeek: It leaks out more and more as Law repeatedly shows that he's NotSoAboveItAll. According to Oda (SBS Volume 82), one of his hobbies is collecting commemorative coins. In Zou, he joined the other male Straw Hats in being excited to meet a real ninja (Raizo) and asking him to perform tricks for them. In Wano, he reveals that he's a fan of comics, in particular [[spoiler:the ones written about Sora and Germa 66 (Sanji's villainous family)]], and is able to explain in detail what kind of abilities the [[spoiler:Germa member Stealth Black, Sanji's counterpart in the comics,]] is able to use.
* CombatMedic: "Surgeon of Death" is more than a RedBaron, though thankfully for Luffy it doesn't actually refer to his medical skills.
* TheComicallySerious: When face-to-face with the Straw Hats' antics, he doesn't seem to know how to react, leaving him with either a deadpan or annoyed expression when they're doing things like tying an incapacitated Chopper to his head. Law also frequently talks about perfectly benign or even good things, [[spoiler:such as the fact that Kin'emon is in the bathroom due to diarrhea and the fact that he successfully healed the children on Punk Hazard]], in such a dour and creepily cryptic way that he makes them sound utterly horrific.
* CoolBoat: His Heart Pirate's vessel, the ''Polar Tang'', is not only a ShoutOut to the Beatles' ''Yellow Submarine'' (which conveniently is Law's colour theme), it is also based from the real life ''TRAFALGAR''-class submarine of the Royal Navy, which is the only one of its class that can traverse through thick ice and operates on nuclear power. Also equipped with 7 jetbeam propulsion, perhaps explaining how it could escape through the frozen water of Aokiji's ''Ice Age'' and avoid Kizaru's light beam simultaneously, two Logia-type Admirals who are hot on their pursuit during Luffy's rescue in Marineford.
* CrazyPrepared:
** Hid regular iron chains to swap with Seastone chains around a laboratory in case he was betrayed and captured by some mistake. Which comes to pass.
** He spends 13 years plotting his revenge against Doflamingo. Once his scheme is put into motion in Punk Hazard, the entirety of Doflamingo's empire -- his SAD production, artificial Devil Fruit manufacturing, arm dealings, business partnership with Kaidou -- starts crumbling down within the span of days.
** As it turns out, there is a purpose to Law saving Luffy in Marineford and then allying with him later. [[spoiler:He firmly believes in the D lineage and what it can do, so allying with a fellow D will therefore increase his chance of taking down Doflamingo and anything that stands in the way of his goal. The fact that Doffy is revealed to be a former World Noble who naturally thinks of the Ds like boogeymen]] is just icing on the cake that Law goes to exploit.
* CreepyChild: As shown in [[http://img3.wikia.nocookie.net/__cb20130708025331/onepiece/images/d/d4/Trafalgar_Law_as_a_Child.png an SBS]], Law used to be one: the scalpel-and-frog toting type. [[spoiler:Subverted, he was a mostly normal kid who was learning to become a doctor. Played straight after Flevance's destruction: he became a suicidal and nihilistic child who wanted to cause as much destruction as possible before dying. He wrapped himself up in bombs and asked Doflamingo if he could join his crew.]] It was because of this that Doflamingo thought he would grow up to be his right-hand man. [[spoiler:Eventually averted: Corazon's efforts to save him as well as crying in sympathy for his pain wore him down and he dropped his destructive desires.]]
* CreepyGood: For a pirate, Law has a surprisingly functional moral compass and really isn't such a bad guy deep down. He admits he does not like killing due to the hippocratic oath (unexpected for a guy nicknamed Surgeon of Death), expresses disgust for Doflamingo's treatment of Dressrosa's citizens and declares his faith in the Straw Hats. Still, that doesn't stop him from being cruel to his enemies and generally intimidating and unfriendly, though.
* CreepyShadowedUndereyes: Which is getting more prominent after the TimeSkip, and appropriately works as nice {{Guyliner}}.
* CynicismCatalyst: [[spoiler:Having his home, friends, and family be completely razed to the ground by the World Government for having a lead disease everyone had completely wrong information about, and for being constantly refused proper treatment because of said wrong information, didn't do his sanity much good]].
[[/folder]]

[[folder:D - J]]
* DangerousForbiddenTechnique: The Op-Op Fruit [[spoiler:can grant eternal youth at the cost of the user's life.]] Doflamingo claims that he didn't want Law to eat the Fruit back when Law was his valued subordinate for this reason.
* DarkAndTroubledPast
** [[spoiler: Law was born in Flevance, a beautiful and prosperous city known for its beautiful White Lead. It was discovered early that the material is actually a slow yet fatal poison, but the government tried to cover up for profit. By the time everyone found out about its side effects, the entire country has succumbed into lead poisoning. As an attempt to cover up corruption, the government spread a rumor about "White lead disease" being contagious and quarantined the country. Citizens wanted to live and tried to break out, which caused a war and ended up resulting in Flevance genocide. Law's parents were shot dead, his friends at school and church were tricked and killed, and his little sister was burned alive. Law escaped by hiding under a pile of corpses. After everything, he decided to join Doflamingo's crew to kill as much people as possible before his inevitable death by poison at 13.]]
** [[spoiler:Corazon, Doflamingo's younger brother, then began helping him search for a cure to his disease. Over 6 months the two grew closer together, as Corazon understood what Law's pain was like and went to great effort to find a cure for him. When Corazon obtained the Op-Op Fruit for Law, the solution to his disease, he was killed by Doflamingo. Corazon had also managed to set an escape for Law from Doflamingo's grasp. Corazon was the father-figure who loved and saved Law while Doflamingo only valued Law as an instrument to die for him; Law then set forth to carry on Corazon's goal to stop Doflamingo's evil.]]
* DeadlyDoctor: "Surgeon of Death" is pretty much a synonym to this trope's name.
* DeadpanSnarker: Practically his primary means of communication with the idiots of the Straw Hat crew and friends.
-->'''Bartolomeo:''' Oi! Trafalgar! I threw yours [wanted poster] out in the trash but just in case you were wondering, it went up to 500 million.\\
'''Law:''' Oh. Thanks. This is me caring.
* DeathGlare: Can do a very frightening one when he gets pissed. It became a RunningGag with Baby 5. He looks so scary that he brings Baby 5 to tears, who then clings to Buffalo for protection.
* DefeatMeansFriendship: According to SBS Volume 84, this is how he met Shachi, Penguin, and Bepo. The latter was being bullied by the former two when Law stepped in and beat the crap out of them; all three were attracted by Law ever since, and the rest is history.
* DefectorFromDecadence: He was once part of [[spoiler:Doflamingo's crew, having been recruited with the intention to mold him into the Third Corazon and Doffy's future right hand man]], but after [[spoiler:he killed Corazon, Law's father-figure]], he defected from it and started plotting revenge.
* DefiantToTheEnd:
** In fact, he starts taunting both Caesar and Vergo when they start squeezing his heart. Noticeable, since it's one of the few times in the Punk Hazard arc that he is not merely stoic and focused.
** [[spoiler:When Doflamingo prepares to shoot him and offers him the chance to instead die with his DangerousForbiddenTechnique and get one wish, Law wishes... for Doflamingo to bring back Rocinante and show remorse to Dressrosa,]] then flips him off and says that he'll never beat the Straw Hats.
* DetachmentCombat: His favorite way of attacking enemies. Unlike Buggy, he does this to other people, disorienting them too badly to fight properly. Fortunately for his victims, they can put themselves back together as long as he lets them live.
* {{Determinator}}: [[spoiler:A natural trait considering he is a D.]] Specific to Law however is he devised a plan over 13 years to have revenge on Doflamingo [[spoiler:for the death of Corazon. When the plan failed, he met Doflamingo in a battle that leads to having his arm severed but still wanting to finish off Doflamingo personally in a failed attack. As Luffy took over the fight, Law remained at the site, determined to observe the outcome and meet the consequences of victory or death.]]
* DishingOutDirt: He can use his Tact technique to make rock spikes come out of the ground to hit foes.
* DifficultButAwesome: The Op-Op Fruit is regarded as having the highest potential out of ''all'' Devil Fruits. When Law first ate it, however, he couldn't even use it to heal [[spoiler:Corazon]] from gunshots and a beating because he needed the medical knowledge of what he was doing first. It also tires him out simply by using it. When he's rested and knows what he's doing? The guy can cut mountains and flip battleships with ease.
* DissonantSerenity: Given the nature of his powers, and the fact that he's a PerpetualSmiler, his fights tend to lead to this.
* DistressedDude: The Dressrosa arc was not kind to him. By the end, he was beaten, shot, had childhood trauma shoved into his face, kidnapped and chained by Doflamingo, carried around helplessly by Luffy, beaten again, and [[spoiler:had his arm ''ripped off'' by Doflamingo]], and had his life force shortened for overusing his Devil Fruit.
* DoctorsOrders: The fact that he can, to an extent, [[RealityWarper warp reality]] (i.e issue order on everything) inside his "room" is a practical application of this.
* DoesNotLikeSpam: He hates bread. Was just a one-off comment when he was staying onboard the ''Thousand Sunny'', but an official artwork by Oda (requested by a fan) showed Luffy and a monkey trying to force-feed Law some bread, which escalated into a full-on brawl. He also doesn't like umeboshi (pickled ume fruit).
* TheDogBitesBack: Law's entire plan was this. [[spoiler:His intentions weren't to go after Kaido; while that would be a nice bonus, his goal was really to get revenge on Doflamingo. If Law doesn't kill Doflamingo himself and dies during their fight, then the destruction of the SMILE factory will ensure that Doflamingo will die anyway at the hands of Kaido.]]
* DomainHolder: Has the power of the Op-Op Fruit, which allows him to perform spontaneous operations (hence the name) on anyone or anything inside a sphere of space created by him, which he calls "Room". He uses his medical knowledge to inflict whatever effects he wants with minimum effort. Also, he carries around a great sword as his scalpel.
* DoomedHometown: He hails from a city called Flevance or "The White City", which was [[spoiler:centred around the mining of the fictional mineral Amber Lead. However, its people eventually suffered from Amber Lead Syndrome as the mineral was poisonous (something that the World Government had hidden from them). The disease turned their bodies white and caused excruciating pain before killing them, and it was also hereditary. Worse, the royalty fled from the island, abandoning them. Because the neighboring countries thought that the disease was contagious, they quarantined the city. Out of desperation, the people of Flevance started a war with the neighboring kingdoms and their city was burned to the ground.]]
* TheDreaded: Law was so notorious and feared that he managed to become one of the Seven Warlords of the Sea.
* DrJerk: His blunt attitude makes him this. Such as when Jimbei asked him what would happen if Luffy keeps rampaging around after Law treated him, he simply said that Luffy's wounds would open up and he'd die.
* EnemyMine:
** What ''he'' wanted his alliance with Luffy to be. Luffy, however, never saw it like that, viewing it instead as a friendship agreement. Though Law still tries to deny it, it's implied that, at some point, [[HonoraryTrueCompanion he stopped seeing it this way, too]].
** Forms a straighter example with Eustass Kid during the raid on Onigashima in Wano, especially once the two of them face off against Big Mom together. Kid is NotInThisForYourRevolution and refuses to officially join Luffy's and Law's alliance, and Kid and Law make it pretty clear that they don't particularly like or trust each other, but they're nonetheless more than willing to work together to bring Big Mom down.
* EnfantTerrible: As a result of his truly ''horrific'' [[DarkAndTroubledPast Dark and Troubled Past]], Law (understandably) became a [[spoiler: misanthropic, sadistic, nihilistic [[CreepyChild Creepy Child]] who sought to destroy the entire world and kill as many people as possible in the time he had left]]. Fortunately, due to [[spoiler: Corazon's love]], he became marginally better, but he's still a pretty immoral pirate nonetheless.
* EstablishingCharacterMoment: His debut shows him of as a rather unsettling pirate who doesn't hesitate to flip off Eustass Kid (who is the Supernova with the highest bounty). This foreshadows that he's not someone to be trifled with, as well as someone who shares Luffy's disrespect for authority. He also shows a softer side by freeing Jean Bart later on.
* EvenEvilHasLovedOnes: Downplayed since he's not actually evil, but is known for his cruelty and sadism, and is certainly guilty of OffstageVillainy. Despite this, Law deeply loves his crew, his biological family, and Corazon.
* EvenEvilHasStandards: Again, less "evil" and more AntiHero, but even he was disgusted when he found out that Caesar Clown was drugging the children of Punk Hazard to ensure that they stayed. Justified given his history: Children being doomed to die due to the build up of toxins in their bodies must have brought back all sorts of memories.
* FireForgedFriends: With the Straw Hats. While he's still exasperated by some of their antics, its clear that he's come to respect them in his time working with them.
* FlippingTheBird:
** Does this to Kid at one point. In the anime, this was [[{{Bowdlerize}} censored]] to Law giving him a smug smile.
** Does it toward Doflamingo after claiming that he'll never beat the Straw Hats, before Doffy starts shooting him.
* FluffyTheTerrible: His crew, the "Heart Pirates". The name doesn't makes sense until we find out Law uses his power for tearing out the live hearts of his enemies. This gets [[{{ChekhovsBoomerang}} even more clever]] as it's revealed that [[spoiler: Law was once a member of the Donquixote family, who uses a card suit motif. The Heart seat of Doflamingo's Top Executives was supposed to be for Law before he defected.]] And as another bonus, [[spoiler:the reason why he left was due to the death of Corazon, Doflamingo's brother. [[{{Bilingual Bonus}} Corazon is Spanish]] for "heart", and Corazon was [[TheHeart Law's idol]], so the "Heart Pirates" might actually be named in tribute to him. It turns out the Heart seat of Doffy's Top Executives was Corazon's, and after his death it was left vacant for ''Law'' to take up.]]
* FlowerMotifs: Dutchman's Pipe Cactus, as revealed in SBS volume 95.
* {{Foil}}:
** To his ArchEnemy Donquixote Doflamingo.
*** Doflamingo is brightly-colored and flamboyant, Law is darkly-colored and grim.
*** Doflamingo is primarily a hand-to-hand combatant who uses the strings from his Devil Fruit as weapons while Law enhances his swordsmanship using his Devil Fruit.
*** There are so many contrasts between them, but perhaps the most important one is that [[spoiler:Doflamingo is a World Noble and Law is a D., whose respective lines are ''also'' arch-enemies. Doflamingo ''claims'' not to care for the conflict, but it's what finally cements his hatred of Law and causes him to give up on recruiting Law back to his side. Law ''actually'' doesn't care for it [[note]]especially since the reason he hates Doflamingo so much is for killing someone important to him, who just happened to also have World Noble heritage[[/note]], but brings it up to exploit how much it pisses Doflamingo off. This also shows their attitude towards their own lineages as well: Doflamingo is obsessed with his World Noble heritage because it's the only thing that puts him above the common people, but at the same time hates the World Nobles themselves for rejecting him. Law doesn't know much about the Will of D. and doesn't care much for it by itself, but still firmly believes in his fellow D. carriers thanks to their many actions throughout history]].
*** As someone who is NotAfraidToDie, he also provides a contrast to Doflamingo's ImmortalitySeeker. Doflamingo, while it hasn't been prominent, has a clear fear of death that led to his obsession over the Op-Op Fruit. Law, on top of being a D, has no fear of death considering that the only reason he survived to this very day was for the sake of the man who saved his life and gave him the chance to live at the cost of his own. Thus, he has no interest in his Devil Fruit's ability to grant immortality and gleefully mocks Doflamingo when the latter attempts to coerce him into using it on him.
** Also to Nico Robin. They probably have the two most horrifying, traumatic pasts in the entire series, in which each of them, as a young child, was the SoleSurvivor of a genocide that wiped their home countries from the map, and gave them both a lasting hatred of the Navy. While both children were regarded as "freaks" at some point, Law's life was very happy, with lots of friends and a loving family, before Flevance was destroyed, and he was more considered a freak after this event due to his disease, while Robin had an unhappy life on Ohara, with few friends and dead or missing family, even before its destruction and was regarded as a freak there due to her powers. They each had a caretaker who was a cross between a BigBrotherMentor and a ParentalSubstitute for them, whom they greatly admire to this day, who was in the Navy, and who had a distinctive goofy smile (Rocinante)/laugh (Saul). Each of these guardians died saving their respective child friend, and were murdered by someone they were close to. Law's caretaker was a former Celestial Dragon who came to believe in the Will of D, while Robin's was a carrier of it himself; as a result, both Law and Robin have an interest in the Will of D as adults. Both of them have rare and highly-sought-after talents, but Law's is his powers while Robin's is her knowledge. They also reacted to their traumatic pasts, and developed from it, in different ways: Law turned his pain mostly outwards and focused on revenge, and become a fairly cold and stern guy who can occasionally show a soft side. Robin's pain was focused mostly inward, giving her a deep self-loathing, and is usually mild and fairly cheerful except for rare moments of anger or coldness. Both had DeathSeeker tendencies that they eventually got over, but Law's were because he was prepared to die to get his revenge, while Robin was prepared to die to spare her friends from her burden. Robin eventually actively admitted that she wanted to live, while Law just more passively accepted continuing to live on after he survived Dressrosa. On a more humorous note, they are both usually TheStoic, but have become increasingly NotSoStoic as a result of their time with the Straw Hats.
** Let's not forget Nami! Both of them came from {{doomed hometown}}s (an unknown island and Flevance), have been cared for by marines (Bellmere and Corazon), and are pretty knowledgeable (navigating for Nami, doctoring for Law).
* FourIsDeath: Fittingly for the Surgeon of Death, his former bounty is at 440 million.
* FreakOut: [[spoiler:While still a young boy attending the academy in Flevance, Law was a kind and devoted child aspiring to become a great doctor like his father and mother while happily going to festivals with his beloved family. Upon the destruction of his homeland, the annihilation of his classmates and family, and being diagnosed with no more than 3 years to live, Law suffered a mental breakdown, becoming unstable and eventually desiring to join Doflamingo's crew so he could destroy everything around him. Only after having been cured of his illness by Corazon did Law have a change of heart.]]
* FreakyFridayFlip: He has the power to do it to other people by using the Op-Op Fruit to switch their hearts. Not literally, mind you, more like a cartoonish heart that seems to represent their soul or whatever. (He can ''literally'' steal hearts, too, but that's an entirely different thing.)
* FriendlyEnemy: He is willing to save a rival pirate because even a relationship with a future enemy is still a relationship. Ironically, he ends up becoming ''friends'' with Luffy for real two years later.
* FromBadToWorse: Played for laughs with his alliance with Luffy. Law looks like he could break down and cry any minute now from the Straw Hat crew's eccentric natures, and all of Law's plans with the Straw Hats just sort of go up in smoke despite his best efforts, planning, and pre-preparation (which turn out to be things like a crude map drawn by Bepo in a marker pen, not even having an official map of Dressrosa). And then played more seriously when Doflamingo outgambits Law and basically gets Fujitora to revoke Law's Warlord status by putting him on the spot (though Fujitora specifically gave Law a way to get around this and Law refused to take it), so then Law had to deal with Doflamingo AND a Marine Admiral at the same time. The whole thing escalated when [[spoiler:Usopp managed to undo Sugar's curse on all the toys]], causing mass chaos in Dressrosa and forcing Doffy to initiate the Birdcage plan; at that point, Law decided that even though he originally wanted to just destroy Doffy's SMILE factory, Doffy now had to be personally stopped, even if Kaido would be pissed off at Luffy and Law as a result.
* FromNobodyToNightmare: Trafalgar Law went from being [[spoiler: the sole survivor of a genocide who was doomed to die as a child to one of the most powerful, feared, and unpredictable pirates in the series]].
* GangOfHats: All of the Heart Pirates (minus the Captain and newest Jean Bart) wears the identical white boiler suit (and orange for the white talking bear). Post timeskip shows Jean Bart wearing the same outfit as the rest of the crew.
* GenocideSurvivor: Trafalgar Law's backstory had his hometown of Flevance massacred by World Government agents due to a lie the government spread about a skin disease called the Amber Lead poisoning, which manifested as white splotches on his skin, and claiming it contagious. In reality, it wasn't and was a generational disease caught from mining for the Amber Lead material. The World Government and the kingdom's royalty ''knew'' about this but didn't disclose it to the citizens and once the symptoms became more and more noticeable, the royalty fled and left their people there to fend for themselves. Law managed to avoid detection by hiding under ''dead bodies'' that were being wheeled out of the country.
* GoodHairEvilHair: Sports a goatee, which usually indicates a mysterious persona, antiheroism, and an outsider.
* GuestStarPartyMember: He allies with the Straw Hats in Punk Hazard, and is present all through Dressrosa, Zou, and Wano. He's become such a prominent one in the canon storyline that it carries over to several non-canon appearances in movies and video games as well, including ''[[VideoGame/OnePiecePirateWarriors Pirate Warriors 2]]'', Coliseum Mode of ''[[VideoGame/OnePieceUnlimitedWorldRed Unlimited World Red]]'', ''[[VideoGame/OnePieceWorldSeeker World Seeker]]'', and ''[[Anime/OnePieceStampede Stampede]]''.
* HalfTheManHeUsedToBe: His trademark. Notably, of all the victims of this during the Punk Hazard arc, only ''one'' of them wasn't a victim of his.
* HandicappedBadass: [[spoiler:Doflamingo severs his right arm in the heat of their battle. Doesn't stop him from grinding Doflamingo's organs to mush with his remaining hand via Gamma Knife, or grievously injuring Trebol using ''his severed arm''.]]
* HappilyAdopted: There's many good reasons why Law considers [[ParentalSubstitute Corazon]] to be the most important person in his life.
* HeartIsAnAwesomePower: When he first demonstrates his power, it seems a bit ''odd'', and he's quite literally dwarfed by Luffy and Kid's physical abilities. Two years later, he's slicing up battleships for lulz and it's implied he became a Warlord by sending the Marines 100 ''still beating'' pirate hearts. [[UpToEleven And then he cuts a mountain in half]], while informing Doflamingo [[NewEraSpeech that the new generation has arrived]]. Later, Doflamingo reveals that the Op-Op Fruit is [[spoiler:considered to be among the most valuable Devil Fruits out there. Specifically, with the Op-Op Fruit's potential to grant someone ''eternal youth'' -- though, ultimately, [[EquivalentExchange at the cost of the user's life]].]] He also literally gained his awesome power from a heart-shaped Fruit.
* HeelFaceRevolvingDoor: Played with. Law is introduced as TheRival for Luffy alongside Kid, then saves Luffy's life, then seems to have gone full Heel by becoming a Warlord, then swings into Face territory when we realize his true intentions in Dressrosa. However, his motives and end goal never really changed, he's spent the whole time gunning for Doflamingo, it just took a long time for that to come to light.
* HeroicRROD: Apparently, using his Devil Fruit powers is physically draining, so Law tries to defy this trope by preserving his energy before upcoming major fights.
* HiddenDepths: Beneath the veneer of cruelty that he's built up for himself over the course of his career as a pirate, Law has real empathy and compassion for others, even if he rarely shows it. He displays genuine disgust for Caesar Clown's experiments, acquiesces to the Straw Hats' requests to save the young children trapped by the MadScientist, and values his partnership with them so much that he goes out of his way to keep them out of his personal conflict with Doflamingo. [[spoiler:To the point that if Luffy dies in the battle against Doflamingo, Law fully intends to follow him as penance for dragging him into what he considers his battle]]. He's also something of a ClosetGeek.
* HonoraryTrueCompanion: Law becomes this to the Straw Hats thanks to their alliance. Initially, Law wanted to keep it as strictly an EnemyMine relationship, but Luffy [[MagneticHero being Luffy]], pulled him closer to the fold. By the time the Dressrosa arc ends, they're pretty much best friends and Law himself is the only one in denial about it.
* HowDoIShotWeb: In the flashback, just after he ate the Op-Op Fruit, he tried to heal the wounded Corazon to no avail. The latter reminded him that this power is "not magic" and his medical expertise should help him.
* IcyGrayEyes: Gray eyes in the anime. Fitting considering how cold and unapproachable he is.
* ImmortalityInducer: According to Doflamingo, [[spoiler: the ultimate technique of the Op-Op Fruit is to grant another person eternal youth. This fact has made it one of the most highly sought-after Devil Fruits in the world. But using it will [[DangerousForbiddenTechnique cost the user their life]]. If word of that ever got out to the masses, Law would become one of the most wanted men ''on the planet''. It's implied that though Corazon's death defined Law's future, Law himself had already lost any chance he had of living a normal life the moment he ate the Fruit]].
* InformedFlaw: Seems as such at first. Law is stated to be a coldly cruel pirate, and even Kid seemed a bit wary of the rumors surrounding him. From what was seen of him, though, Law seems to have a very friendly relationship with his crew, took pity on an enslaved pirate captain, and risked his life to save Luffy for no particular reason. Subverted to high hell, though, given the "resume" he sent to Marine HQ for a position among the Seven Warlords of the Sea.
* InSeriesNickname: He's been referred to as "Traffy" by the Straw Hats since the Punk Hazard Arc, as Luffy cannot pronounce Law's surname to save his life.
* IntergenerationalFriendship:
** With Wolf, the eccentric old inventor that allowed a young Law, Bepo, Shachi, and Penguin to live with him for several years on Swallow Island. He's also the one who invented and built the ''Polar Tang'', eventually gifting it to Law when he formed the Heart Pirates.
** Also applies to Rudd, a police officer on Swallow Island who gets along well with Law and excitedly shows Wolf a newspaper featuring the latest exploits of the Heart Pirates in the North Blue.
* IOweYouMyLife: For saving his life, Law became indebted to Corazon. [[spoiler:At the same time, he feels the freedom he obtained because of Corazon can't be repaid until he accomplishes Cora's greatest wish to stop his evil brother's madness.]]
* ItAmusedMe:
** Or rather, It ''Will'' Amuse Me. His stated reason for saving Luffy from the Marines was because it'd be "too lame" if he had died then and there.
** This is Law's fighting style in general. His ability allows him to cut his opponents' body parts without actually killing or harming them. In his first on-screen fight in the series, he was '''juggling the body parts of Marines.'''
** After defeating Tashigi and leaving her alive, and then after chopping her in half, she demands that Law finish her off. He instead taunts her and decides it would be more fun to cut her into even smaller pieces.
* ItsPersonal: He made things personal with [[spoiler:his former boss, Donquixote Doflamingo, when he betrayed him and killed two loyal subordinates, along with setting him up to be royally fucked over]]. It all started however, when [[spoiler:13 years ago Doflamingo murdered his younger brother Corazon, who had saved Law's life.]]
** [[spoiler:He ended the alliance with the Straw Hats, revealing to Doflamingo that he only intended to have them destroy the SMILE factory to ensure that no matter what happens, Doflamingo will die, as he was the main target all along. Law never intended to go after Kaido, as his desire to have revenge on Doflamingo for murdering Corazon 13 years prior,]] and as much as he would love to see the chaos that would enfold after Doflamingo's death, he is fully prepared to die if necessary to get his revenge.
** Later on, he would also admit outright [[spoiler:to Luffy that despite doing as many indirect things as possible to screw Doflamingo over, due to how his plans against him started to fall apart, Law himself decides to settle with hurting Doflamingo directly like several others have wanted to do as well.]]
* JadeColoredGlasses: Zig-zagged somewhat. He began as a somewhat creepy but still kind child, then became a cold, cruel, evil, heartless, sadistic, misanthropic nihilist after [[spoiler: the genocide of Flevance]], but then ended up softening slightly due to [[MoralityPet Corazon's influence]]. Nowadays, while he's still cold, cruel, and sadistic, he's also capable of compassion and empathy, and he dearly loves his [[TrueCompanions crew]] and Corazon, has become quite close to Luffy, and tends to treat his allies pretty well.
* JerkWithAHeartOfGold: In his backstory, he used to be quite the jerk (a jerk with a bad past, but still), but then his idol Corazon's actions made him more caring towards the lives of his closest associates. Nowadays, he's still rather cold to everyone, but if someone close to him needs helping, he will do it.
** He has a soft spot for sick (and poisoned) children, which is not surprising considering his past.
** He does have some regard for innocents, and seems to want to keep them out of his or the alliance's conflicts:
*** [[spoiler:He clearly is enraged by Doflamingo's treatment of the Dressrosan citizens. When asked what his final wish is, Law demands that Doflamingo bring Corazon back and follows that with a demand for Doffy to "lick the ass of every single citizen in this country".]]
*** He also does his best to protect the Straw Hats from Doflamingo, even stating that they have nothing to do with the conflict between Law and Doffy.
*** He points out to Luffy that their alliance staying in Zou after it was attacked by Jack is a bad idea, asking what will happen to the citizens there if Zou is attacked again.
** Seen more in Wano when, after Luffy becomes a hero of Leftover Town by stealing fresh food and bringing it to them, Law expresses disgust at the idea of a benevolent pirate... and yet, despite his reputation as a "cruel" pirate, it's established in the previous chapter that he avoids killing people whenever possible. [[WhatYouAreInTheDark And was even stealing food for some of Wano's starving citizens himself]].
[[/folder]]

[[folder:K - P]]
* KatanasAreJustBetter: His weapon of choice is a nodachi, which he uses as a sort of "doctor's scalpel" when using his powers to chop things up at long range.
* KiManipulation: He is a confirmed user of Haki, which is probably how he was able to cut Smoker's heart out.
* KickTheDog: "The weak do not have the right to choose how they die." is a line he tells Tashigi when she berates him for not killing her after slicing her apart. It's a line he picked up from his former captain, Doflamingo.
* KubrickStare: Complementing his intimidating presence to the opponents. Occasionally accompanied by the mysterious vibes of {{Hidden Eyes}} and {{Face Framed In Shadow}} from underneath his hat.
* LackOfEmpathy: Law tends to hold a certain disregard for anyone who isn't [[TrueCompanions his crew]], [[MoralityPet Corazon]], or a valued ally. For example, despite having suffered the same fate himself as a child, Law suggested leaving a group of sick and dying children behind on Punk Hazard since they would be "too much of a burden to deal with," though to be fair, he acquiesced without much protest when Luffy still insisted on saving them. Furthermore, although Law was cut to the core when he realized that Doflamingo never really cared about him and only ever planned to use him, he still manipulated Brownbeard into viewing him as his savior and callously discarded him after exploiting him for all he was worth. Lastly, even though Law suffered a [[spoiler:genocide of his hometown]], his original plan to avenge Corazon by having Kaido kill Doflamingo ran the risk of putting the innocent citizens of Dressrosa in danger from Kaido's wrath as well.
* LaserBlade: His Gamma Knife technique has him making a small blade of PureEnergy that is used to cut through internal organs.
* LaserGuidedKarma:
** For all his deeds, he gets his own heart removed and squeezed by Vergo, briefly passing out in agony.
** For all the limb-cutting that he did, he [[spoiler:gets his right arm severed by Doflamingo. Painfully, of course.]]
** That being said, he also gets the positive version of this, in a big way. He and his crew risked their lives to rescue Luffy from Marineford despite having absolutely no obligation whatsoever to do so, and in spite of the fact that Luffy, as a fellow pirate searching for One Piece, is actually a rival of theirs. As a result, Luffy already likes and trusts Law when they meet again in two years and gladly agrees to ally with him; this alliance eventually leads to [[spoiler:Luffy and his friends/allies defeating Doflamingo and bringing down his entire empire -- a goal Law had spent ''thirteen years'' trying to accomplish -- while saving Law's life multiple times in the process]].
* LastOfHisKind: Law is the [[spoiler: only known survivor of the country of Flevance]].
* LeanAndMean: While he isn't extremely thin, he does stand out since the standard male in ''One Piece'' is either [[{{TheBigGuy}} big]] and [[{{HeroicBuild}} very muscular]] or [[{{TheBrute}} massive]] and [[{{TopHeavyGuy}} extremely muscular.]] He's not as mean as many of the pirates in the setting, but is significantly colder and more anti-heroic than the Straw Hats.
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=8P3H9-L3Dgk Trafalgar Law Eyecatcher]]
* LoveMakesYouCrazy: A noble and platonic example. All throughout Dressrosa, Law delivered some long, dramatic, pretty [[TheStoic uncharacteristic]] speeches that claimed that everything he was doing was for the sake of his "most cherished person", [[ParentalSubstitute Corazon]], [[WorthLivingFor that he only bothered to live]] this long in order to fulfill his wishes, and that he would happily destroy the entire world if it was for his sake. He specifically refers to [[spoiler: Corazon as his ''savior'']]. And even after having his arm cut off and being on the verge of death, he still forced himself to crawl forward towards Doflamingo, all for the sake of avenging Corazon.
* LoveMakesYouEvil: Not truly evil, but definitely willing to go to some pretty dark places. However, he's a very sympathetic and platonic example. For the sake of avenging and fulfilling the greatest wish of his "most cherished person", [[ParentalSubstitute Corazon]], Law did a lot of downright ''nasty'' things, which included, among others, sending 100 still-beating hearts to the World Government; initially being willing to abandon sick and dying children -- despite the fact that he suffered from the same fate as a child and that he was disgusted with the person who did this to them -- because healing them would be too big of a bother; knowingly tricking Brownbeard into thinking of him as a savior and then [[YouHaveOutlivedYourUsefulness callously discarding him later]]; being willing to destroy the entire world; and much, ''much'' more.
* MaddenIntoMisanthropy: The Law that [[spoiler:appeared before Doflamingo looking to destroy everything in sight]], and even the Law today, is the way he is because of his very traumatic childhood: [[spoiler:He grew up in Flevance, or "The White City", where the people were slowly dying from Amber Lead poisoning. While studying to become a doctor and grow up to treat the illness, the war the country became involved in killed his family and everyone he ever knew. And he only survived by ''hiding in the dead bodies'' carted out of the quarantine zone.]] That would screw up anyone.
* MadDoctor: When he treats Luffy and Jimbei, he notes that they won't be able to feel the pain anyway because they already passed out, even if he doesn't use anesthesia, and determines that it's going to be a "fun" operation. Not to mention the deal with his "operation room" power and the antics he does with it.
* MeaningfulName:
** The Heart Pirates were most likely named after Corazon, which means "heart" in Spanish.
** Law's full name, Trafalgar D. Water Law, seems to be taken from two famous battles in real world history, the Battle of Trafalgar and the Battle of Waterloo. This takes on a deeper meaning when one considers that [[spoiler:the name of Big Mom's sword is ''Napoleon''. Napoleon faced his greatest naval defeat in the Battle of Trafalgar and he was ultimately defeated in the Battle of Waterloo. Fittingly, Law achieves the impossible while working with Eustace Kid by dragging the Emperor drown from her throne]].
* MagnificentMustachesOfMexico: Subverted when he's rocking one in the Dressrosa Arc, during his disguise towards Green Bit.
* MessyHair: In fact, without the hat he resembles Luffy. He's still [[UnkemptBeauty quite]] [[MrFanservice attractive]] though.
* MindOverMatter: His "Tact" technique, which allows him to levitate stuff inside Room.
* MorallyAmbiguousDoctorate: Subverted. Despite the way he [[TrustMeImADoctor announces his profession]] (on top of being a pirate), and the fact that his RedBaron is "Surgeon of Death", he is a pretty damn skilled doctor, because he was able to save both Luffy and Jimbei from the brink of death, despite how serious the injuries they had received during the war were. Ironically, he probably doesn't have the ''One Piece'' world's version of a medical degree due to his circumstances as a teenager and young adult. Being on the run as a pirate makes higher education challenging. However, both of his parents were doctors, so it can be argued that he was instead apprenticed very young.
* MrFanservice: Just look at him and try to say he isn't.
* TheMostWanted: The [[SuperpowerLottery Ope-Ope Fruit]] is stated by Doflamingo to be the "ultimate Devil Fruit" thanks to its [[SwissArmySuperpower extreme versatility]], [[SuperDoc miraculous medical applications]], and [[ImmortalityInducer ability to grant eternal youth]] ([[EquivalentExchange at the cost of its user's life]]). When it was last up for sale thirteen years ago by the Barrels Pirates, it's estimated worth was at least 5 billion berries to the Marines and other potential buyers. When combined with his own personal bounty (500 million) as of the Wano arc, this makes Law as valuable and sought after as '''Gol D. Roger himself'''.
* MultipleGunshotDeath: Subverted. [[spoiler:Doflamingo became infuriated with Law's revenge ploy; mindlessly emptying his pistol into Law while ranting and belittling him for not holding the heart seat and misunderstanding the tribute to Corazon that Law represents.]] Doffy even says along the lines of "Luffy will be surprised to find your body" after he does it. Law isn't killed however, having [[spoiler:switched his body with a corpse before being shot.]]
* MysteriousMiddleInitial: The D in his name is attributed to the mysterious "Will of D", which somehow connects Law and a few other notable individuals throughout the story to the World Government and the Celestial Dragons.
* NamesToRunAwayFromReallyFast: He's named after a ([[spoiler:or rather, two]]) historical war, ''and'' a notoriously cruel real life pirate. And dude is surely good at stirring up chaos if he wants to.
* NervesOfSteel: During the moment [[spoiler:when Doflamingo chooses to taunt him over Corazon's failed attempt to save Dressrosa, Law dismisses the idea that the situation could have been averted, which even surprises Doflamingo on how level-headed he is. Then, when he taunts the beaten and bloodied Law again and offers to let him die via the Immortality Surgery in exchange for one last wish, Law smiles, agrees... and wishes for Doflamingo to bring Corazon back to life and then lick the asshole of every single citizen in Dressrosa, before promptly flipping him off and telling him that he'll never beat the Straw Hats or get Caesar back]].
%% * NewEraSpeech: Gives an epic one to Doflamingo.
* NiceHat: To the point when he gets his heart back and is ready to fight he calls back his hat and puts it on his head. Ever since his childhood he's always seen with a white bowler hat. After the TimeSkip it is changed into a white newsboy cap. All with the same black patterns on them.
* NinjaLog: His "Shambles" move allows him to switch things around -- that includes switching himself with objects. He even uses a literal log when saving Sanji from Doflamingo.
* NobleDemon: Law may have sent one hundred hearts of pirates to the Marines as his application to become a Warlord, however he reacts with disgust to Caesar's disregard to the children, knowing they would die and the MadScientist just doesn't care.
* NoBadassToHisValet: Despite his massive power, having a huge bounty, and being an ally to Luffy, Bartolomeo does not care about him at all as he throws Law's new bounty poster in the trash and refuses to give him any of his provisions, but is more then willing to give it all to Luffy.
* NoCelebritiesWereHarmed: Bears more than a passing resemblance to Mystery, the Pickup Artist, in both looks and dress. May help explain his popularity. Also to the well-known Italian Moto GP World Champion Valentino Rossi, who is also conveniently known as ''"The Doctor"''.
* NotAfraidToDie: Comes with being a D. He doesn't fear death and faces his doom with a smile on his face.
** While having his heart squeezed by Caesar and Vergo, instead of begging for mercy Law merely taunts them into squeezing it ''harder''. This, along with Law's own admission that he doesn't care if he has to die to get his revenge on Doflamingo, were one of the first real indicators of his real name.
** Likewise, after having his arm cut off and beaten by both Doflamingo and Trebol, Doflamingo offers Law anything in exchange for the immortality operation. Law just flips him off, tells him where he can stick his offer and states the Straw Hats are gonna kick his ass before Doflamingo shoots him again.
* NotDistractedByTheSexy: Not outright pointed out, but Law is one of the very few men not taken by the extreme beauty of Boa Hancock and the rest of the Kuja Pirates. It could be that he is "a doctor before all else" kind of person and that his mellow and laidback personality makes it much more difficult for him to be visibly flustered and swept away.
* NotSoAboveItAll: Since their alliance, Law has been simply shocked at how goofy the Straw Hats are, despite their reputation for being a thorn in the World Government's side. This has actually been happening in small doses ever since the alliance was established. The more time Law spends with the Straw Hats, the more susceptible he is to taking part of their hijinks. It's not long before he realizes that Luffy's not going to be the UnwittingPawn that Law expected him to be, or that he was never really in control of the alliance in the first place.
** Law keeps his cool as being the OnlySaneMan... until Sanji says he's making sandwiches for breakfast and Law admits he doesn't like bread, only to make a shocked face as he realizes to have said something silly.
** In the Zou arc, Law joins the crew on speculating cool things that a ninja like Raizo can do. He specifically says "a clone jutsu would be nice." Sure enough, clone jutsu is one of the techniques Raizo displays seconds after.
** The Wano arc reveals that Law, as someone who originally lived in the North Blue, was an avid comic book fan and used to read the comic strip of Sora and the fight against the evil Germa 66. [[spoiler:He therefore immediately recognizes Sanji's Germa raid suit and explains in detail what "Stealth Black" [[{{Invisibility}} is capable of.]]]]
** While fighting [[spoiler:Big Mom along with Kid and Luffy, Law immediately take part in a stupid challenge Luffy declares (whoever dodges out of the way of one of Big Mom's fireballs first loses) as soon as Luffy says he'd lose if he didn't play]].
** When he's [[spoiler:fighting Big Mom alongside Kid, he gets jealous when he thinks Kid's starting to upstage him. It says something when ''Kid'' of [[AxeCrazy all people]] is the more reasonable one in that situation]].
* NotSoStoic: The antics of Luffy's crew are beyond even his ability to resist.
* NotWhatISignedOnFor:
** After finding out just what Caesar Clown was doing with the kids, he basically told him that he wanted no part of it and was done working with him.
** On a more humorous note, Law's pirate alliance doesn't quite turn out the way he'd anticipated, mostly because Luffy sees the alliance as a friendship pact rather than a business relationship. Which seems to have rubbed off on Law as well, since [[spoiler:Admiral Fujitora tells Law he'll be given a pass for everything he's done if he just says the Straw Hats are his minions (since the Seven Warlords are allowed to do such things) and Law defiantly says that Luffy is his ''partner'']].
* OhCrap:
** His reaction upon realizing that [[spoiler: a) Doflamingo did not actually abdicate his post on the Warlords, b) that he used that whole ordeal as a way of luring him into his territory, and c) that he and Admiral Fujitora are closing in on him and preparing to kick his ass.]] A part of that is the implications of what [[spoiler:Doflamingo did. Fooling the entire world just for a mere ten people is something way beyond the power of a Warlord. The only people who have the power to pull off such a thing... are the '''''World Nobles'''''.]] It's understandable that Law would freak out at the possibility that [[spoiler:one of the Seven Warlords of the Sea is a World Noble, let alone the most psychotic and dangerous one.]]
** Another one is when he realized that [[spoiler:Doflamingo is going to use the Birdcage.]]
* OmnicidalManiac: [[spoiler:After witnessing everyone he loved died as a child, he desired to become like Doflamingo and cause as much destruction as possible, also feeling that's all he could accomplish before he died of his lead disease. This is no longer the case after Corazon managed to save him from his illness and showed him compassion.]]
* OnlySaneMan:
** In comparison to the Straw Hats. As time goes on, it becomes evident that not even he is immune to their hijinks.
** Zigzagged, when compared with his own crew, who have a penchant for SuperSentaiStance and other goofy behavior. However, for example in Chapter 919, [[spoiler:Law talks about Kin'emon being in the bathroom all day due to diarrhea in such a way that he made it seem like Kin was dead and haunting the land as a ghost]]. ''Luffy'' even called him out for being so creepily cryptic!!
* OOCIsSeriousBusiness: In Chapter 798, Law speaks with retired Fleet Admiral Sengoku about Cora's death, both of them reminiscing over the fact that the only other person who truly remembers and loved Donquixote Rocinante is someone who, at any other time, would be their mortal enemy. Throughout the entire exchange, Law is nothing but respectful and polite to Cora's adoptive father, only raising his voice once to [[ParentalSubstitute express his own love and devotion to Corazon]]. All Sengoku requests in return for [[spoiler: Cora's HeroicSacrifice]] is that [[WorthLivingFor Law continue to live a free life]], which is what Rocinante would've wanted.
* OrganTheft: Law’s Devil Fruit allows him to steal the hearts of people, either for a quick kill, to blackmail them into doing his business or as an insurance that they won’t attack him later on, as he did with Smoker, Tashigi and Monet.
* PapaWolf: In Chapter 938, when [[spoiler: Shinobu accuses Bepo, Shachi, and Penguin (who've been captured) of spilling the details of the Alliance's now-leaked plans to the enemy. He furiously insists that his crew would rather die than betray them and that Shinobu shouldn't insult them, states that he'll prove this to her after they're rescued, and gives her a massive [[DeathGlare Death Glare]] when she states that captured alliance members should just be killed to keep them from talking.]]
* PerpetualSmiler: Which verges on DissonantSerenity. The trait is downplayed after the timeskip.
* PersonOfMassDestruction: Especially considering he ''cut a mountain in half''.
* PetTheDog:
** He and his crew show up to save Luffy at Marineford, completely out of nowhere and with no obligation to do so. While it's certainly possible that he had his own agenda for doing so [[spoiler:(or because of Luffy and Law both being carriers of the Will of D.)]], the fact still remains that Law greatly risked his and his crew's lives to save a rival pirate he only met once.
** On a similar note, when Law tells Buggy to hand Luffy over to his care, Buggy gives him both Luffy and Jimbei, since he'd been guarding them both. Jimbei was a complete stranger to Law, and given the nasty reputation he'd acquired and the fact that he was only there for Luffy, Law could have easily left him behind; however, he instead treated and saved both of them nonetheless.
** Despite his desire for revenge on Doflamingo, Law has no desire for the Straw Hats to get in the crossfire, stating that their conflict [[ItsPersonal has nothing to do with them]]. This leads to him taking many risks to save their lives.
* PsychoticSmirk: His ''glorious'' one when finally getting access to the SAD room causes a lot of people to once again question his intentions.
[[/folder]]

[[folder:R - Z]]
* TheReasonYouSuckSpeech: Gives a rather nice one to Doflamingo.
* RedOniBlueOni:
** The Blue to Kid's Red when they were first introduced. Kid is a FieryRedhead while Law is a snarker with blue/black hair.
** Later becomes the Blue to Luffy's Red.
* RelativeButton: Go ahead, insult Donquixote "Corazon" Rocinante in front of Law. [[SchmuckBait We]] [[TooDumbToLive dare]] [[RoaringRampageOfRevenge you.]] When Doflamingo insulted Corazon right in front of Law, Law's response was to -- [[spoiler:despite being on death's door -- drag himself over to Doflamingo and electrocute his liquefied insides.]]
* RequiredSecondaryPowers: Notably averted, at least in regards to the medical applications of the Op-Op Fruit. The Fruit is only useful to someone who is ''already'' a trained doctor, implying that Law's great feats of abilities with his Fruit come not just from any inherent power of the Fruit itself but from his own knowledge of medicine and anatomy. [[spoiler:When he tried to heal Corazon as a child, he had to be reminded that the Fruit was not magic]].
* TheReveal: In the past, Buffalo and Baby 5 wanted to know his full name. He eventually caved, revealing it's [[spoiler:Trafalgar '''''D.''''' Water Law]].
* RemovedAchillesHeel: [[spoiler: Awakening his Devil Fruit gives Law the ability to create a ''mobile'' version of Room, negating his previous weakness of not being able to effect anything outside the sphere. [[DiscardAndDraw Though]] this comes at the cost of the area of effect becoming a lot smaller]].
* RichesToRags: In the flashback scenes, he began as a little boy who comes from a wealthy, reputable family of doctors who used to live in a castle-like home and wore tailor-made suits. Was forced to crawl among the dead bodies as a fugitive after the Flevance tragedy struck before he eventually encountered the Donquixote Pirates at the dumpster and became one of his flunkies.
* RoaringRampageOfRevenge: Trafalgar Law has dedicated half his life to one against Donquixote Doflamingo for [[spoiler: murdering Donquixote Corazon/Rocinante, and the events resulting from this revenge spree led to the Dressrosa Arc]].
* SadisticChoice: Gives one to [[spoiler:Doflamingo after he and the Straw Hats capture Caesar. Either Doflamingo quits the Seven Warlords of the Sea and goes back to being a regular pirate, after which Law will give Caesar back to him to continue making SMILE Devil Fruits for Kaido, or he doesn't and lose the manufacturer for SMILES. [[MortonsFork He's screwed either way]], because if he stays, he won't be able to produce SMILES for Kaido and will have to face his wrath, and if he quits, the Admirals will hunt him down. Ultimately fails since Doflamingo has the connections to ''fake'' quitting the Warlords.]]
* SecretLegacy: Law was completely unaware of the significance of [[spoiler:the "D" in his name, just like most of the D. carriers in the series such as Luffy -- all he knew is that he had to keep it a secret. However, Corazon, and presumably Doflamingo, knew about it, or at least enough to warn Law to stay away from his brother]].
* SecretSecretKeeper: [[spoiler:During their entire time together, Rocinante/Corazon hid the fact that he was a Marine from Law because didn't want Law to hate him. Once he indirectly revealed the truth to Law during his final face-off with his brother, Law's thoughts reveal that he had known the truth all along, but didn't care]].
* ShockAndAwe: Adding to his surgery motif, he can apparently use his palms as defibrillator paddles in an attack called "Counter Shock".
* SoleSurvivor: Excluding the royal family who escaped early, he is the last known survivor of [[spoiler: Flevance.]]
* SpaceMaster: He has the power of the Op-Op Fruit, which lets him create a sphere of influence called a "Room" that serves as his "operating table". Law can cut, rearrange, and piece together any object or living being in any way he chooses while they remain whole and intact. Even if he cuts you in half, your top and bottom will work and move just like normal, except now separated from one another. He can also do SwapTeleportation of objects in the Room.
* SpannerInTheWorks: The one ultimately responsible for the clusterfuck that is the Dressrosa arc. By allying with Luffy, Law put the Straw Hats on a collision course with the Donquixote Family, and the resulting conflict has escalated to the point that it involves nearly every major power in the world, [[spoiler:including the Revolutionary Army and the World Nobles]]. Thing is, he doesn't give a shit about ''any'' of it. [[spoiler:Everything he has done for the last thirteen years to this very day has been for the sake of avenging Corazon's murder and killing Doflamingo. If the world has to go to shit in order for him to have Doflamingo's head, then Law will gladly drag this world to hell with him]]. Also, during the final battle of the arc, [[spoiler:despite being incapacitated by Doflamingo, Law still manages to interfere in the fight from the sidelines.]]
* SpellBlade: His Radio Knife technique has him channeling electricity to his nodachi to cause WoundThatWillNotHeal.
* TheStoic: Although he initially is shown to smile often, after the timeskip he's almost perpetually frowning and rarely flinches.
* StraightManAndWiseGuy: The Straight Man to Luffy's Wise Guy. Law is very serious and clashes often with Luffy's idiocy and quirkiness.
* SubmarinePirates: His crew primarily rides in a submarine. It becomes very useful when they have to flee safely from Akainu.
* SugarAndIcePersonality: Seems cold, heartless, and a tad evil, [[spoiler:but actually harbors deep feelings of affection towards his late saviour Corazon, who's possibly the only one who saw his amiable smiling side since the Flevance tragedy.]] Usually calm and calculating, he can be blinded by hot-blooded fury, especially concerning Doflamingo. The guy is also generally polite in his speech and even takes off his hat at the dining table but didn't hesitate to rudely flip other people off, either.
* SuperDoc: Law is quite possibly the best doctor in the ''One Piece'' world, as his Devil Fruit allows him to perform all kinds of miraculous surgeries and he's studied medicine since he was a kid.
* SuperpowerLottery: Literally ''everything'' inside his "Room" is his to command, and post-TimeSkip he's been shown [[spoiler:to create battleship- and even ''mountain''-sized "Rooms."]] There's no known way around it once you're inside the "Room," either, apart from having sufficient Haki. His power of surgery, aside from conveniences like swapping people's bodies, taking out their heart, and personality transplants, is also later revealed to be able to [[spoiler:grant eternal youth at the cost of his own life]]. Even so, Law actually has several ways to easily OneHitKill characters while inside his Room, whether it be through dismembering them from afar, teleporting them away, or taking away (or crushing) their organs. What keeps it from being a StoryBreakerPower are the drawbacks from its use, which include draining Law's stamina and sometimes even his own lifespan. Doflamingo outright stated that many people consider this to be 'The Ultimate Devil Fruit'.
* SwapTeleportation: He can swap two objects' positions as long as they're both inside his "Room". He can also swap himself with another object or person.
* SwissArmySuperpower: His powers revolve mainly around surgical techniques.
** His main use of his power is to cut things with his sword before using "[[MindOverMatter Tact]]" to jumble things up.
** He can use his hands as defibrillators for short range ShockAndAwe attacks.
** Within his Rooms, he has SwapTeleportation of the objects inside them.
* SymbolMotifClothing: Law wears the emblem of the Heart Pirates on his hoodie, on the hem and sleeve of his all-new dapper {{Badass Longcoat}} and on the chest of his most recent fabulous feathery-necked outfit. Besides, all the Heart Pirates including his submarine, even his own Transponder Snail, wear the insignia with pride. [[spoiler:The emblem was created in honor of the man who saved his life and whom he now dedicates his life to avenge, Corazon.]]
* TakingYouWithMe: What he tried to do to [[spoiler:Doflamingo.]]
* TallDarkAndHandsome[=/=]TallDarkAndSnarky: Both apply, as he is fairly tall and slender, [[MrFanservice very good-looking]], a much darker shade of gray morality-wise than the Straw Hats, and quite the DeadpanSnarker.
* TattooedCrook: Has several "smiley" tattoos on his arms (Oda says jolly rogers in North Blue are typically this shape), as well as DEATH on his fingers. Also has a big heart-shaped tatoo on his chest. In fact, [[http://onepiece.wikia.com/wiki/File:SBS71_3_Law_Tattoos.png he's got tats all over his upper body.]]
* ThenLetMeBeEvil: After the world [[spoiler: abandoned and killed everyone in his country because of their Amber Lead Syndrome]], and after the world [[spoiler: continued to ostracize, hate, and even try to kill him for being a "white monster"]], Law decided that, hey, he might as well be the monster everyone says he is and [[spoiler: join the Donquixote Pirates in an attempt to destroy the world]]. While he lost [[spoiler: the utter nihilism he had as a child because of Corazon's love]], he's still a pretty vicious and feared pirate.
* ThouShaltNotKill: While fighting [[spoiler:Basil Hawkins]], he expresses a distaste for killing. [[DownplayedTrope However]], he is perfectly fine with people dying ''as a result'' of his actions as seen with Vergo[[note]]Law left him helpless in a room about to explode.[[/note]], Monet[[note]]Law gave her heart to Ceasar, passing it off as Smoker's. When Ceasar tried to kill Smoker by stabbing the heart, she was killed.[[/note]], and Doflamingo[[note]]While Doflamingo didn't die, Law's plan was to essentially provoke Kaido into killing him.[[/note]]. Though it was shown that Law was willing to make an exception for the Donquixote Family, since he explicitly states many times that he wants Doflamingo dead.
* TigerVersusDragon: Rather subtle compared to most, but it exists between him vs. Doflamingo. Him having "Tora" (tiger) in his name (and sometimes called "Tora-guy") and having a vendetta with Doffy, [[spoiler:a Celestial Dragon.]]
* TogetherInDeath: After doing everything he can in [[spoiler:the final fight against Doflamingo before being forced to leave the rest to Luffy, he requests that Cavendish leave him in the flower fields to watch the battle. If Luffy wins, he wants to be there to see it; if Luffy falls, then as penance for dragging his partner ("friend" being implied) into this fight, he'll allow Doflamingo to kill him and join Luffy and Corazon in death. Cavendish agrees -- on the caveat that he'd be allowed to stay as well, and tells Law that he won't die unless Cavendish does first]].
* TookALevelInBadass: Pre-time skip he was a rookie captain, just about strong enough to reach the halfway point in the Grand Line with a bounty of 200 million Berries, and was barely capable of facing a Pacifista allied with Kid's crew and survive. Two years later, his bounty doubled before the WG approached him for a Warlord position; he apparently regularly heads off to a closed-off, highly toxic island [[HailfirePeaks with extreme climates on both halves]], and home to [[EverythingIsTryingToKillYou ex-cons, a variety of strange creatures]] [[ArsonMurderAndJaywalking and giant children]] calling it his "favorite holiday spot"; and he is capable of defeating Vice-Admiral-level opponents.
* TrademarkFavoriteFood: He likes onigiri and grilled fish.
* TrueCompanions: Law clearly loves and is protective over his crew, and they clearly reciprocate his feelings. This is emphasized in Chapter 938, where Law [[spoiler:snarls at Shinobu when she suggests that his crew betrayed them, unhesitatingly beginning to abandon the plan and throwing himself in harm's way in order to save his crew, and gets positively ''furious'' when she threatens to kill them]].
* TykeBomb: Law was raised by Doflamingo to be his right-hand man. To this end, he taught him just about everything he (and his execs) knew about fighting.
* UndyingLoyalty:
** To Donquixote Rocinante aka Corazon. Law outright states that Corazon is his most cherished person, that the only reason he bothered to live was to fulfill Corazon's goal, and that he would happily destroy the entire world and die as long as it was for Corazon's sake. Law's entire grudge with Doflamingo stems from Doflamingo [[spoiler:killing Corazon]], which causes Law to dedicate his entire life, as well as being willing to die, in order to bring Doflamingo down in his revenge. Law was so devoted to Corazon that he is willing to do what Corazon ''wouldn't'' do in the end, no matter how horrible his older brother was, how much he hated him, and how much Doflamingo honestly needed to die -- ''[[DeadlyEuphemism pull the trigger]]''. In addition to all of that, it doesn't hurt that it's heavily implied that Law named his crew after Corazon and even tattooed his smile onto his chest.
** Law also feels this towards [[TrueCompanions his crew]]. He [[spoiler:snarls at Shinobu's suggestion that his crew would ever betray them, unhesitatingly beginning to abandon the plan and throwing himself right into danger in order to save them once they were captured, and becomes murderously ''enraged'' when she threatens to kill them]].
* UngratefulBastard: Doflamingo considers Law to be this, since he spent years raising Law to be his top lieutenant only for Law to turn against him. However, he also acknowledges that if the specific incident that Law is raging against him for had never happened, then Law would have been [[spoiler:the third "Corazon".]]
* UnspokenPlanGuarantee: Downplayed. During his and Luffy's fight with Doflamingo, Law says something about their "secret plan"; Luffy, who was really angry at that point, screams "screw the plan!" and goes after Law instead. Turns out Law's "plan" was [[spoiler:relying on Doflamingo to make Luffy angry enough, and as Luffy comes at him, Law activates Room and switches himself with the distracted Doflamingo -- who then gets hit by Luffy's Red Hawk. He reverses it when Luffy manages to make his way back up to Doflamingo, revealing he isn't dead after he was shot again. This time Luffy rushes Doflamingo but Law switches Luffy with himself, getting close enough to land a fatal blow on Doflamingo.]]
* UsedToBeASweetKid: Despite his dour appearance even as a child, Law was a much warmer person than he is now. [[spoiler:It was his country's war and the illness that caused it, that took that away from him. Doflamingo's influence seemed to be the nail-in-the-coffin. Thankfully for all, his close relationship with Corazon helped him regain the little compassion and mercy he ''does'' still have]].
* VisualDevelopment: Law's appearance after the Time Skip coincides with his new Warlord title, level of power, and manners: from the laid-back, smiling yellow-themed hoodie-wearing hipster-style Supernova to the lugubrious terrifying Warlord who is clad in black, {{The Grim Reaper}}-like {{Black Cloak}}, complete with the {{High Collar Of Doom}}. Between Punk Hazard and Dressrosa, he goes back to the hipster look (seemingly coinciding with his start to fall into the pace of the Straw Hat crew), before hybridizing the two for his "disguise" outfit in Dressrosa. However, he is ''always'' wearing the [[CostumeInertia same spotted skinny jeans.]]
* WhenHeSmiles: Post-timeskip, Law has pretty much [[CharacterizationMarchesOn become a]] PerpetualFrowner, and the smiles he does sport are usually some kind of SlasherSmile. So, on the few occasions that he ''does'' smile genuinely (such as during the celebration of Doflamingo's defeat, after reuniting with his crew, and a few times as a child in his flashback), they definitely stand out.
* WildCard: Big time, even among the Supernovas. He saved Luffy from being executed by the World Government, but then quickly makes it known that [[IWasJustPassingThrough he doesn't consider Luffy an ally.]] Post time-skip, he ''joins'' the World Government, becoming a Warlord... but only in an effort to pin down Doflamingo and he loses the title in Dressrosa. And he's perfectly willing to ally himself with Luffy to betray his current partner and take out one of the emperors, because Luffy is also a WildCard and it can only help to double down in this situation.
* WildTake: He is hilariously prone to these in the company of the Straw Hats. Luffy alone pulls out more of these from him than he had in the ''entire first half of the manga''. And that was back when he was more relaxed.
* WorthLivingFor: [[spoiler:Law, along with his friends, family, and city, were used up by the World Government to dig up the Amber Lead for wealth, and then all of them were cruelly abandoned thanks to a disease that would kill him before he even reached adulthood. Because of that, he wanted to destroy everything in sight -- until Corazon showed him love and compassion, and eventually succeeded in getting the means to cure Law of his disease. Law fully intended to spend the rest of his life with him -- but then Corazon was killed.]] Now, the ''only'' reason why Law bothered living to this very day was [[spoiler:to kill Donquixote Doflamingo, Corazon's murderer]]. [[spoiler:After Doflamingo's defeat, Law is finally able to get closure by meeting Corazon's surrogate father, Sengoku. Holding a burden that Corazon might have been motivated to serve the Will of D, Sengoku assures him that his actions have nothing to do with the D but were made out of love for Law, and that he should continue living free if he really wanted to pay tribute to Corazon's actions.]]
* WorfHadTheFlu:
** He gets taken down by Vergo because Vergo has his heart. Once he gets it back, Vergo goes down in one move.
** By the time he finally got his one-on-one fight with [[spoiler:Doflamingo, he had fought Admiral Fujitora and Doflamingo at the same time, while having to watch Caesar and then protect the Straw Hats.]] So, he was pretty tired heading in, which is even worse for him than normal as his Op-Op Fruit specifically relies on his stamina.
** When he fights Doflamingo on the castle roof, he's been hauled around in seastone cuffs with untreated bullet wounds combined with the exhaustion from his earlier fights. On top of that, he's also facing Doflamingo and Trebol ''alone'' since Luffy got sidetracked by Bellamy.
* WorthyOpponent: Certainly considers Luffy to be one. Time will tell if it sticks.
* WoundThatWillNotHeal: He can inflict this with his Devil Fruit powers, to an extent that ''even a Logia user cannot regenerate their form.'' Just ask Trebol.
* XanatosGambit: His plan for revenge on Doflamingo, which he allied with the Straw Hats for. Law made it so that even if Doflamingo kills him in their battle, the destruction of the SMILE factory will ensure that Kaido will finish the job for him and kill Doflamingo himself.
* YouHaveOutlivedYourUsefulness: Downplayed, since Law didn't kill him, but he still manipulated Brownbeard into viewing him as his savior and then callously discarded him after exploiting him for all he was worth.
* YourDaysAreNumbered: When he first met Doflamingo as a child, Law claimed he only had 3 years left to live. [[spoiler:This is because of the amount of Amber Lead in his body, the poison which would ensure he would die before he reached adulthood, just like his peers, had they not been killed beforehand. He survived because Corazon had stolen the Op-Op Fruit from other pirates and was responsible for saving Law. The Fruit granting the ability to modify and restructure the body was the perfect solution to removing the Amber Lead]].
