The Straw Hat Pirates: Wolfcove Island

Luffy is a young man of average height with shaggy black hair, round black eyes, and a slim muscular build. He is renowned for his trademark yellow straw hat with a red hatband (from which he gets his epithet "Straw Hat Luffy"), which was lent to him when he was young by the legendary pirate captain, "Red-Haired" Shanks, who in turn received it from Gol D. Roger. Before the timeskip, his main outfit consisted of a red vest with three gold buttons, light blue denim shorts cuffed just above his knees, and tan sandals. Luffy also has a scar with two stitches underneath his left eye, which he earned as a child by stabbing his face to show Shanks that he was tough enough to be a pirate. He was severely wounded by Akainu in the Summit War of Marineford, leaving a large X-shaped scar on his chest. Luffy's most dominant traits are his apparent lack of common sense, his utter fearlessness and unwavering belief in himself. He generally marches at the beat of his own drum, unwilling to approach anything in a delicate or nuanced matter. That said, Luffy has a penchant of being able to see through the heart of the matter, often able to accurately call out someone's personal flaws such as Koby's cowardly nature or Kuro's weakness as a pirate. He is profoundly ambitious, frequently declaring he will become the Pirate King and devoting his entire being into being one. Luffy's personality can be described as childlike, in the sense that he tends to go to the extremes. He can either be extremely greedy, especially in cases of food, who his crew is, and adventure; or extraordinarily selfless, going so far as to virtually sacrifice himself to avenge or protect his friends, crew, and family. This childish mentality does not prevent him from often getting to the root of the problem and allowing him to figure out the simplest way of solving it.

Zoro is a tall, muscular young man with lightly tanned skin. He always carries his three swords along with him, bundled up with a green haramaki over his right hip, allowing him to easily draw them with his left hand. Of the three swords he has on his person, he has always been seen carrying the Wado Ichimonji, while his other two swords have varied over time due to them being destroyed and subsequently replaced with progressively better ones. Although his right hand is usually seen resting over them, he can also use this hand to pull his swords out before sitting down. He has three identical gold earrings on his left earlobe. Zoro normally keeps a black bandana tied around his left bicep and ties it around his head when he is fighting seriously against an opponent. During and after the two-year timeskip, Zoro gains a new scar running down over his left eye, which is implied to be a permanent injury, as it is always closed. His frame gets larger, showing considerably more muscle mass, and his hair has gotten shaggier, while slicked back. He retains his bandana, haramaki, pants, and boots, but instead of a henley, Zoro now wears a long, open dark green coat closed on his waist that's held by a muted red sash, into which his three swords are tucked. He has also grown noticeably taller, as he is similar in height to Robin.

Nami is a slim young woman of average height with ginger (orange) hair and brown eyes. Many characters seem to consider her to be an attractive woman. She has a blue tattoo on her left shoulder, which represents mikan, and pinwheels (a homage to Bell-mère, Nojiko, and Genzo, respectively), where she used to have a tattoo for being a member of Arlong's crew. From the Return to Sabaody Arc through the Fish-Man Island Arc, Nami's appearance underwent a few significant changes. Her hair has grown longer, reaching down her lower back with a single long hair stand hanging on the left side while still maintaining her bangs. Her breasts have also grown much larger, and she has developed more of an hourglass figure, similar to Nico Robin's. Nami has also grown slightly taller. After the timeskip, her default outfit consists of a revealing green-and-white bikini top, tight low-rider blue jeans, orange high-heeled sandals, and a pair of pearl-like earrings. Since arriving to the New World, Nami sports a new belt that is black with a "Beli" symbol on it, where she keeps the pieces of her Sorcery Clima-Tact on the right side.

Usopp is a slim tan-skinned teenager with medium-length black curly hair, prominent lips, and a long nose. Usopp inherited his famous nose from his mother, while the rest of his face closely resembles his father's. During the Straw Hat separation, after landing in the Boin Archipelago, Usopp grew obese from overeating. Like the rest of the males of the crew, he wore one outfit for the majority of the series before wearing different clothing by the end of Paradise. Usopp usually wore an olive green plaid bandanna, a blue and white striped armband on his left arm, along with special sniper goggles (he also has a pair of clear rectangular goggles that he sometimes wears in situations where he does not have his sniper goggles, like when he first met the Straw Hat Pirates or when his sniper goggles were stolen by Mr. 2), brown overalls with a white sash and no shirt underneath. He also carries with him a yellow satchel, which he stores all his tools and gadgets in. After the two-year timeskip, Usopp has become much more muscular than before and has grown his hair out. He has become "manlier" and is slightly taller than before. Usopp now has a new pair of goggles around his neck (his sniper goggles weren't shown) and has some headphones or ear protectors on. He also now has a little goatee along with a new white wide-brim sun cap he wears on his head. He also has a new pair of rolled-up yellow pants with red suspenders and a pair of boots. His trademark yellow satchel has been replaced with a red one, but he still has his blue and white striped wristband on his left arm.

Sanji is a tall, muscular young man with long legs and jaw-length blond hair which he keeps brushed over one side of his face. Before the timeskip, this was the left side. After the two-year timeskip, he switched his hairstyle so that it covered the right side. It also appears that Sanji's hair is scruffier after the timeskip. After the two-year timeskip, Sanji now covers his right eye, shows his left eye, and has grown his hair just slightly longer. He also sports a dark anchor style facial hair and stubble on his upper lip. Sanji's neck has gotten thicker as well, similar to Luffy and Zoro's. He has grown taller and therefore remains nearly the same height as Zoro. He wears a black double-breasted suit (which is sometimes depicted as dark blue) with gold buttons with a yellow dress shirt together and a brown tie.

Vivi is a young fair-skinned woman of medium height with long wavy light blue hair, with two locks hanging down, one on either side of her head, which started out at about chin-length but were past her shoulders by her last appearance before the timeskip. According to her father, Vivi holds a strong resemblance to her mother. She most often wears her hair pulled back into a ponytail, and brown eyes. She has a slender body but tends to wear less-revealing clothing than Nami and Robin do. Vivi has been seen wearing several different high heeled shoes, including white high heel boots, white high heel sandals, and blue wedges. Though she is a princess, she rarely wore clothing that would suggest her royal status while traveling with the Straw Hats, although she started to do so more regularly after her coming-of-age speech. After the timeskip, she wears her hair down but held back by a clip, and it seems a bit shorter than before. Like most female characters since the timeskip, her hourglass figure has become more pronounced. A notable facet of her appearance is that when she was a member of Baroque Works, she seemed to have been drawn in a slightly different way. While playing the role of Miss Wednesday, she looked older, and her facial features were much more angular. She wore her ponytail in a very high position until she was attacked by Miss Valentine, where a few strands of her hair were slashed off with her hair bead. It was only after her true identity was revealed that she was drawn to look more like a teenage girl, with slightly bigger/rounder facial features and a less shapely body. This was more noticeable in the anime than the manga, as the animators drew her in such a different way that she could almost be mistaken for another character. As a child, she had shoulder-length hair tied in a ponytail.

Most of the time, Chopper is a toddler-sized human/reindeer hybrid, but his Devil Fruit abilities allow him to change his appearance depending on the situation. Chopper's left antler is braced at the base by a metal plate because it was reattached after being broken during his search for the Amiudake when he was younger (when he thought the Amiudake could cure Hiriluk's disease) and ran into the leader of his old herd, who severely injured him. He usually wears a large pale red/pink fuzzy top hat with a sideways medical cross (given to him by Hiriluk) and a maroon pair of shorts. He also sometimes wears a blue backpack that has the same sideways medical cross as his hat. He also has a remarkable blue nose. As Oda's style evolved and many readers commented on how cute Chopper was, Chopper was given a much more "chibi" like appearance, meaning that when in his preferred transformation (which he calls Brain Point), he has a larger head and eyes and a less defined muzzle than earlier in the series. Many female characters, such as Nami, Robin, Makino, Porche, Shakky, and Vivi find Chopper very cute. There are even males that find Chopper cute such as Foxy and Breed. After two years, Chopper is significantly leaner. He is less potbellied than he was in earlier seasons and his arms/forelimbs are also skinnier. It is arguable that since leaving the cold climate on Drum Island, he has lost significant body fat. The color of his fur has changed from brown to gold, and according to Nami (when she and Chopper reunite on Sabaody), the texture has gotten softer.

Nico Robin is a tall, slender young woman with shoulder-length black hair styled in a classic hime cut and eyes that have dark, wide pupils (her eyes are depicted to be brown in the manga as well as the tenth and twelfth movies; while in the anime, her eyes are depicted to be blue cerulean). She also has a long, thin, and defined nose. In the anime, Robin's skin tone has a slightly darker tan unlike in manga-colored artworks where it is lighter. Robin also resembles her mother greatly, with the exception of her hair color and style as well as having a slightly darker skin tone than her. Robin's limbs are very long, especially her legs, contributing greatly to both her fighting capabilities (given the nature of her powers) and overall height. From the Return to Sabaody Arc to near the end of the Fish-Man Island Arc, Robin's black hair (also lightened in color) has grown longer, which reaches to her lower back, and it is pulled back, so it reveals more of her forehead and ears. After the timeskip, her outfit now is a long salmon sarong skirt that has a design of a green seaweed with red and yellow flowers on the side with ruffles that bares her hips with a partially-zipped short-sleeved navy blue (sometimes purple in manga and some other media) leather vest with a V-neck line and an image of her Devil Fruit or of an actual Chrysanthemum morifolium is printed on the left breast near the shoulder that exposes her stomach, darker pink (sometimes red in other media) high heeled pumps, and a lavender pink backpack. She wears white sunglasses with orange lenses (black in the manga) which she hangs on her forehead and is seen wearing them during the battle with the New Fish-Man Pirates in the Gyoncorde Plaza.

As a direct result of the modifications that he conducted upon himself as well as the years spent as a ship dismantler, bounty hunter, and street thug in Water 7, Franky is a powerfully built man with a height of at least seven feet, making him the third-tallest member of the Straw Hat crew, after Jinbe and Brook. His forearms are relatively enormous while his biceps are comparably small. His chest is well-toned with large abs and pectoral muscles. He has brightly colored blue hair and blue star tattoos on his forearms. Franky's eyebrows are rather long and stern, and he has three prominent lower Matsuge on each eye. His chin is very angular and tapers off in three pointed clefts. Franky has an equally angular prosthetic nose made of iron with several rivets and jagged edges, the only replacement part of his exterior body that is not covered in artificial skin. Over the two years he was on his own, Franky used Vegapunk's blueprints to drastically reconfigure his body, repairing the damage he accidentally caused to himself and replacing some old functions his body used to have with better and more powerful implements. Franky's hair is now controllable and can change different styles instantly by pushing his nose for more than three seconds. While he used to wear it up in a pompadour style, he now frequently changes his hairstyle, typically whenever he wears a new outfit. However, he reverts to his original pompadour style whenever he is inside General Franky.

Brook is an extremely tall skeleton dressed in formal attire complete with a top hat and cane. Standing at 266 cm (8'8½") in height, he is the second tallest member of the Straw Hat crew, having been edged out by Jinbe. Despite having no skin, he still has an afro which he says is because his hair has very strong roots. Brook's style was that of a gentleman consisting of a coat, top hat, trousers, and afro, which were black, while the inner linings of his coat were yellow-orange. The cravat that was tied in between his coat and around his neck was blue. The outer covering of Brook's cane sword which he carries was purple. Also, due to his many years of seclusion, his clothes were somewhat tattered. During the Return to Sabaody Arc through Fish-Man Island Arc, he changed to more colorful and high-end clothes, as though to represent a rock star. He had heart-shaped sunglasses, a yellow feather boa, a new top hat with a giant crown on the brim, and orange-red trousers with a floral design. Despite being a skeleton, he grew to 277 cm (9'1") during the two-year timeskip.

Jinbe is a large blue whale shark fish-man and the current tallest member of the Straw Hat Pirates. He has a stocky build similar to that of a sumo wrestler and a face that is commonly associated with various Japanese demons such as the oni. His yellow eyebrows and sideburns are distinctly shaped like those found on such demons, in addition to a bulb-like nose and an angular lower lip pointing upwards. He has a lightning-shaped scar that can be seen from his left sideburn and reaching over his left eye which he obtained sometime between Otohime's assassination and meeting Ace. He also possesses two tusk-like conical lower fangs associated with Oni as well; the rest of his teeth from the upper and lower rows are pretty much the same, albeit much smaller. He also has a severe underbite, which makes room for his huge fangs. He has long, two-toned black hair, with two long stripes, colored gold in the manga and white in the anime, coming from the roots over his forehead and trailing down the back, a topknot, and tuft of hair on his chin with a slight green hue. This topknot did not exist during his time as a member of the Sun Pirates, instead his shorter and flowing black hair trails off halfway to a light color concentrated at the back of his head. He kept his chin clean-shaven before joining the Sun Pirates, after which it gradually grew out over time. His hands and feet are also webbed, typical for a fish-man, and his limbs that are somewhat thin in comparison with his enormous girth. His gills (which are pale and pinkish in color) are in between his shoulders and neck.

Zoro usually maintains a very stern, serious, and distanced personality, but often loses his temper in a goofy and exaggerated comical style. It would seem however, that this anger is the only emotion that Zoro often feels comfortable showing. Outside of situations where he feels confident in battle, he tends to smile or laugh the least out of the Straw Hats and rarely fools around with the rest of the crew and likes to distance himself more to sleep or train. In fact, his defeat at the hands of Dracule Mihawk and subsequent vow to Monkey D. Luffy is the only time since his friend Shimotsuki Kuina passed that Zoro has been seen crying in the series. Even in moments that are particularly tough on the crew and would warrant sadness, Zoro chooses to maintain a quiet solemnity rather than outwardly express his emotions. He has been shown to believe to a degree that these emotions can hinder his judgement as a swordsman: when Ohm asked him if he was out for revenge upon discovering Tony Tony Chopper wounded and unconscious, he replied that he does not like to fight for reasons like that. Despite this assertion, though, he cares deeply for his crewmates and wishes to protect them at all costs, telling Ohm that in spite of his preference for fighting without a motivation he can feel one coming on.

When it comes to the subject of women, Sanji is extremely amorous and a self-admitted romancer at heart; obsessively flirting with any attractive woman he sees to the point of being labeled a pervert. Even as a child, while working in Baratie, Sanji would become love struck with attractive female customers and end up making mistakes in the process, much to Zeff's irritation. Since, and a while after, this romantic nature is a hassle for the rest of the crew in times of crisis. Returning to Sabaody Archipelago after his two years on Momoiro Island, Sanji became even more perverted due to not having seen a woman in two years, making lewd faces when he so much as thought of beautiful women (primarily his crewmates, Nami and Robin) and acted strangely when he got close to 'real' women, causing others to question about his health. He is even attracted to Kaidou's son, Yamato, despite the latter identifying as a man and being addressed with masculine terms while biologically being a woman, and therefore was in favor of him joining the Straw Hat Pirates. One of Sanji's most easily noticeable characteristics is the kind, calm, cool, and collected manner in which he carries himself. He tends to speak in a very composed manner, even in dire situations, and rarely acts without thinking. His demeanor in a lot of ways can be compared to that of a secret agent. This is amplified by the fact that he very often enjoys a smoke, and in the anime, they tend to play smooth music with jazzy undertones when he speaks. He quite often makes comedic exceptions to this, such as when in the presence of beautiful women, or when angered by a crew member.

Nami is greedy and will do mostly anything for money and treasure, accepting any challenge that comes along. Her love of money stems from her childhood, where she lived a poor life and was often upset at having little wealth despite the love of her adopted mother. She became even more obsessed when her family’s poor status led to her mother’s death. She grew up constantly getting money through theft to pay for the freedom of her village. While she will send in Luffy and the rest of the crew to meet the demand, the one thing she will not do is sell out a comrade, no matter what the sum. She has several times put her own crewmates in debt over trivial matters (like Luffy for tearing her coat and Zoro for borrowing Beli 100,000 only not to spend it and return it later). Her usual charge for repaying the debt is 300% interest, and she will often bring up these debts in order to get someone to do something for her. She takes control of the amount of money the crew spends, ever aware of the crew's spending habits (such as Luffy's desire to spend all they have on meat) and tries her hardest to avoid it getting spent all at once. From time to time, Nami enjoys casual and leisurely activities, and the most common of these is reclining in a deck chair, often to sunbathe, read, or relax under the shade of a parasol umbrella. Nami sometimes sits in her chair after taking a swim in the Thousand Sunny's pool. In fact, the pictures for her wanted posters were taken while she posed next to pools. While she is in her deck chair, she may be accompanied by Robin or presented a refreshing snack or drink by Sanji, but she does not take kindly to the rest of the crew's rambunctious antics on the ship, which tend to disturb her as she relaxes.

Since first introduced, Usopp has been cowardly, known to constantly lie and enjoys telling tall tales to both friends and strangers alike. He is generally seen as the comic relief of the Straw Hats as well as the weakest member of the crew. Despite his cowardly disposition, he is unselfish, compassionate, and strives to become a great pirate as well as better himself. He also works hard to keep the crew safe and help his fellow crew members accomplish their own dreams as well as his own. Usopp is one of the more sentimental Straw Hat Pirates, and cries or loses his temper in moments of emotional stress. At the start of the series, Usopp was an easily frightened, anxious, insecure, and compulsive liar. Unlike Nami (whose cowardice is linked to just wanting to stay alive), Usopp's cowardice was the result of his fear and insecurity, especially when faced with uncertainty. Usopp is able to put aside his fear during more desperate times: despite being afraid, he faces those fears for the sake of his friends and people he barely knows. Usopp is also an adept liar, which can be useful in certain situations. Although many of his lies are outrageous and easily seen through, they've been shown to be a useful distraction at times, especially against gullible opponents. At times, it even succeeds as a deterrence albeit for a short period of time until his enemies figure out his bluff. He often incorporates his bluffs into his arsenal with mixed results. He is also a skilled sham salesman, often selling worthless items to people by lying about what their capable of doing. Sometimes, his bluffs appear to actually happen.

Vivi does not fit the stereotype of a needy and authoritative princess, never demanding any special attention or prioritizing herself above others. In fact, she usually puts the needs of others far above her own and is hesitant to rely on others or ask for help with her own problems. In particular, she places an enormous value on the citizens of her country and the lives of her friends. Vivi's selfless nature could be seen especially when she asked the Straw Hats to make a detour to get medical help for Nami instead of continuing straight to Arabasta, even though she knew her country was in a state of emergency. This selflessness applies to herself as shown when in a precarious of being kidnapped by CP0 and possibly made into a slave, Vivi was more worried for her friend Shirahoshi who was being targeted by a World Noble. She is also extremely brave and determined, going up against powerful enemies for her friends' sake, even when clearly outmatched. Her selflessness and sense of responsibility push her to carry her country's burden. She is slow to anger and quick to forgive but fiercely loyal to her friends, her family, and her country. Because of this loyalty and bravery, she is willing to make virtually any sacrifice, such as when she was willing to allow her feet to be cut off to escape Mr. 3's candle prison. Vivi can stay calm in bad situation and act quickly when she sees a way out.

Chopper is naïve and extremely timid towards unfamiliar humans, often acting like a child because he does not know any better. Like Luffy, he is easily impressed at things like beams, cannons and hidden abilities. He is a coward at times like Usopp and Nami, although his cowardice can be attributed to his childishness and overall lack of trust in his own fighting skills (a contrast to Nami's self-survival-based cowardice and Usopp's insecurity-based cowardice). He would rather run and hide than fight but becomes more courageous when others are there to support him. Chopper is more or less on a journey to define himself, seeing almost anyone on his team as a role model and in some cases, imitate their behavior, especially Usopp. Being the youngest, Chopper is the most emotional Straw Hat and very much considers the crew his "family", when forced to be part of the Foxy Pirates during the Davy Back Fight Chopper was distraught and cried that he was a Straw Hat and only stopped bawling when Zoro ordered him to "man up". After the timeskip, Chopper seems to have grown more confident, much like Usopp. He no longer strives to be looked at as a human, now only wanting to "be a monster that can help Luffy" as he put it. He even has grown mature enough to smack his crewmates, mostly Zoro and Luffy, when they try to do something stupid or extreme. He also seems to have outgrown most habits mentioned above, but his habit of peeking still remains. Immensely kind-hearted by nature, Chopper is an upright friend and caring companion who will try anything to overcome a task given by his team. Even back when he was Hiriluk's assistant, he would go to extreme lengths just to acquire a mushroom which he thought would cure Hiriluk's chronic disease. Chopper seems to be very forgiving of those close to him, for when Usopp wanted to rejoin the crew at the end of the Enies Lobby Arc, he called out to Luffy and Zoro, although they were ignoring him completely.

Out of all the members of the Straw Hat Pirates, Robin is the most serene and has rarely been seen to act comically. She approaches life and the world at large in a calm and collected manner and is overall one of the most emotionally stable members of the crew. She is kind, polite and treats Luffy with more respect than the most of the crew, even when he acts impulsively, to the point where she will smile and laugh at his antics rather than berate him. Together with Zoro, she is one of the members that support Luffy's decisions unconditionally. When the crew is sailing, Robin is usually reading and investigating data from the places they visit. She is very wise and very patient in everything. Robin does not play a specific role in the ship, but she can foresee what can be found somewhere and that (in her own words), is of advantage to others. Luffy considers her a very intelligent member. Through her heritage on the island of scholars, Robin is an archaeologist and historian who seeks the comfort and freedom to study the mysteries of the world. She is the quieter, more reserved crew member, rarely having outbursts of emotions (occasional exceptions being sweat drops, and when she cried out to Luffy and the Straw Hats from the Tower of Justice during the Enies Lobby Arc). She even appears calm while speaking ominously around her crewmates. She has an "adult charm" about her, as stated by Sanji. Being described as the "mother" by Oda, she in kind has shown maternal care for younger characters like Chopper, Momonosuke, Toko and Jewelry Bonney.

Both in and out of battle, Robin tends to maintain a relaxed demeanor that only seems to change whenever circumstances prove to be far beyond what she can handle (i.e., a hopeless situation). More often than not, however, she exhibits nigh-unshakable calmness and reserved behavior against inferior adversaries, to the point where she typically displays by using her powers to satisfy minor necessities (i.e., using a pair of arms sprouting from the ground to form a make-shift seat).

As a result of her violent past, she is very merciless in combat and does not shy away from using lethal force. She will break the necks or spines of her enemies without hesitation, even when they cry for forgiveness, as demonstrated when she in her fight against Yama. Despite her tendency to remain calm and collected, she can be quite intimidating and forceful when she wishes, as demonstrated when she essentially forces Brook to stop fooling around and continue his explanation. She even states her willingness to be a demon if she has to be, especially for the people counting on her. Robin has a somewhat macabre side to her, and often points out gross or morbid facts, usually to the disgust of Nami or Usopp. Robin will usually be the first to speculate that a crewmate has met or will meet with a horrible fate, often going into grisly detail. In other instances, she will express enthusiasm for anything with a horror theme.

Franky is an exhibitionist and a self-proclaimed pervert. He is strong-willed, eccentric, free-spirited, and often has a blatant disregard for rules and norms. He does whatever he wants whenever he wants, though he usually wants little more than to build powerful ships or protect those he cares about and at times can appear very eccentric compared to most of the crew because of his strange mannerisms and knack for building odd things (such as his Franky Centaur). He is also highly self-aggrandizing, reveling in how "SUPER" he is and how brilliant his body or inventions are. Despite his strange and goofy behavior, Franky has demonstrated himself to be among the most mature and reliable of the Straw Hats, making an effort to entertain young crewmates while still keeping serious matters in mind. Depending on the situation and the people he is dealing with, Franky can be quite an altruist, as he is quick to defend other people and take action if his friends are harmed; he also holds the belief that no matter what a person is like, they should never be prejudiced or exterminated simply because of who they are. This often causes him to befriend and defend the wrongfully feared and persecuted. Because of his unbiased and protective attitude, he is quick in making friends and allies with the most unlikely of individuals, such as street thugs and pirates. He is seen as a 'big brother' figure and is admired by many for his efforts to protect them, such as Nico Robin and the Franky Family. Monkey D. Luffy and Franky share some personality traits, with the exception of fighting needlessly, and both grew to respect each other during the events of the Enies Lobby Arc, despite the disputes the two had during the Water 7 Arc. It has been shown that Franky's personality can alter somewhat, depending on the beverage in his system.

Brook is an eccentric character with a distinct personality of his own, like the other Straw Hat Pirates. While he looks like and fancies himself to be a gentleman, he does possess vulgar and perverted manners and habits such as asking to see women's panties (Although in Camie's case, in a subversion of his usual habit, he asks if she can lend him some money), yelling impatiently for food (a trait shared by Luffy), and occasionally burping and farting conspicuously. Despite this behavior, he still remains very polite, formal, and soft-spoken, usually referring to people using the respectful "-san" ("Sir") and always speaks to everyone, even enemies, in a very courteous manner. He appreciates the simplest of things: from a gesture of kindness, the company of others, and walking in the sunlight after receiving his shadow back. Brook was moved to tears at just being able to share a dinner with people after decades alone in the Florian Triangle. His reactions to different occurrences can be somewhat extreme, often comically so. For example, when the Straw Hats were alarmed at him for being a living skeleton, he forgot the object of fear was actually himself and also began to panic. Although he tends to display more extreme emotions at times, Brook has been known to over-relax when he is told to stay calm. He is also very patient, having stayed on his former crew's ship for years, waiting for the day when he would eventually be reunited with his shadow. However, due to his rudeness, he can also be impatient about things like waiting for dinner to be served. Brook's most notable trait amongst others, however, is that he cracks "skull jokes" about himself being a skeleton complimented with his distinct laughter of "Yohohoho" even if there is no one around to hear him. (e.g. "I can't believe my eyes! Not that I have eyes!") When Chopper broke one of his jokes by saying what he intended to say beforehand, Brook became temporarily depressed. And a Love For Music.

Despite his pride, Jinbe appears to put his priorities and principles over his honor and is not above retreating from an otherwise unfinished battle (despite being shamed or openly mocked by an opponent) if it was for the sake of the greater good. He also does not seem to hesitate from encouraging others to do likewise for a similar cause, as seen when he pleaded and managed to convince Luffy to prioritize Ace's safety first over avenging his brother's loss against Blackbeard. Jinbe has also displayed great humility regarding his personal strength and status, a trait most unique among the Seven Warlords of the Sea. This was made apparent by his willingness to even lose his status for his refusal to fight against the Whitebeard Pirates. Also, unlike his former crewmate Arlong, the fact that he is willing to aid a human (Whitebeard) as well as team up with others separates him from the other fish-men. Whereas Arlong would never dream of such a thing (even Nami's recruitment into his crew was near slavery), Jinbe proves to be able to treat some humans as equals and also acknowledge when he owes one a debt. While he is a fish-man with great emotional control, he is empathetic and understanding of the pains of others, such as being brought to tears when Luffy broke down from losing his brother in front of him after he had awoken from the battle at Marineford. Jinbe is also capable of crying aloud when someone dear to him is lost, such as Ace and Tiger.

Although Jinbe is normally calm and collected most of the time, he does have a humorous side similar to Zoro. When he saw Shirahoshi outside of her room, he was immediately shocked wondering why she was outside and then became even more shocked seeing an injured Hachi. When Luffy paid little attention to Jinbe's story about what happened during the last two years, Jinbe bemoaned to the rest of the crew commenting on what it is like having Luffy as a captain. He is also not above laughing when something amuses him, as when Judge was yelling at Luffy about all the perceived "flaws" Sanji has that Luffy mistook as compliments, Jinbe busted into laughter, commenting he was going to have fun with his new crew.

Karoo is a duck of yellow-brown plumage, with black-tipped wings and tailfeathers. Typical of his species, he bears a black band around his bill and stands roughly as tall as the average human; his feet are tetradactyl, with ostrich-like talons (unlike the webbed feet of normal ducks). His default wear consists of a blue-and-white chullo (typically unbuckled), pink goggles, and a large saddle carrying multiple saddlebags. When travelling, he prefers to wear a barrel-shaped canteen around his neck, complete with drinking-straw. For the most part a comic-relief figure, Karoo is generally intelligent enough to grasp most human speech and situations, but often engages in bizarre—sometimes dimwitted—behavior, up to misinterpreting some of Vivi's simplest commands. As a counterbalance to his headstrong mistress, he is also easily frightened, easily shrinking—if not outright fleeing—at signs of danger. At the same time, Karoo is undyingly loyal to Vivi, and by extension both the Arabasta Kingdom and the Straw Hat Pirates. In times of need, he has always embraced this loyalty over any fears, unflinchingly risking his life on multiple occasions, up to and including using his own body as a shield. Karoo's loyalty to his friends has also made him very determined to help in any way he possibly can both in and out of battle. Examples of this include how he helped Luffy and Usopp to defeat the Baroque Works agents in Little Garden, how he arrived with the Super Spot-Billed Duck Troops to help the Straw Hats out of the desert and save Vivi from Mr. 2 Bon Kurei in Arabasta. Despite this, Karoo, like Vivi genuinely cared for the Straw Hats and became very attached to them, as he tearfully parted ways with them alongside Vivi, and has been seen happily keeping tabs on their exploits alongside her as well. When given the opportunity, he can also prove something of a glutton, and has been known to ignore Vivi's orders on conserving water even during long desert travels.

The Thousand Sunny is a brigantine, a highly versatile type of ship that relies on the skills of its navigator. The ship has a lawn on her deck, complete with a swing and a slide, as well as an observation tower for a crow's nest. The huge masts give the ship extreme maneuverability. Like the Going Merry, the figurehead is an animal's head, specifically a lion with a stylized mane. Due to the mane's ambiguity, the lion was mistaken for both a sunflower and a sun during the ship's construction, much to Franky's frustration. The ship holds sixteen cannons: seven traditional cannons on each side of the ship and two specialized air cannons—the Gaon Cannon in the figurehead and the Coup de Burst cannon astern. By the admission of Jinbe, a masterful helmsman, the Thousand Sunny is a good ship,[3] which Franky admitted that Jinbe was the best candidate to bring out the ship's full potential after hearing of his talent as a helmsman. The Thousand Sunny is amongst the most technologically advanced ships in the series. Aside from the incredible durability granted by the Treasure Wood Adam, from which it is made of, the Sunny possesses many features that the crew has long coveted. It also includes some nice additions Franky added himself, most of which are, naturally, powered by Cola, usually from the ship's Energy Room. These additions include the Soldier Dock System and other unique internal contraptions. Rooms: The boys room. The girls room. The kitchen. The sick bay. The aquarium bar. The library. Usopp Factory. Franky's workshop. And Zoro's training room and crow's nest.

Haki is a mysterious power that allows individuals to harness their own spiritual energy for various superhuman feats. As this energy manifests from willpower, it is theoretically open to all of the world's living creatures; the vast majority, however, is unable to use it, either because they are unaware of its existence, or due to lack of adequate training to achieve mastery. Haki users are common in the New World, rare in Paradise, and virtually non-existent in the Four Blues. Current understandings of Haki define three distinct types, each tied to a different ability: sensing others' spiritual energy to anticipate their movements, producing a protective coating of energy from one's own body, and—for a certain group of "chosen ones"—overwhelming the willpower of others. Haki and its users have underpinned many significant events throughout the series—notably, Shanks used it to drive off the Lord of the Coast and save a young Monkey D. Luffy's life. The term "Haki" was first used much later when Blackbeard was commenting on Luffy's bounty in Jaya, and was hinted at during Shanks' visit with Whitebeard. The underlying concepts of Haki were introduced during the Sabaody Archipelago and Amazon Lily Arcs. The concept was clearly explained later on by Rayleigh to Luffy at the start of the latter's training on Rusukaina Island.

Observation Haki (見聞色の覇気, Kenbunshoku no Haki?), which gives the user a sixth sense of the world around them, allowing them to sense the presence, strength, and emotions of other people, even if they are out of sight or far away. It also grants limited precognitive abilities, allowing the user to sense their opponents' intentions and predict their actions and attacks before they happen. An advanced level of Observation Haki allows the user to actually foresee a short period into the future. Armament Haki (武装色の覇気, Busōshoku no Haki?), which allows the user to use their own aura as armor to defend against attacks, as well as make their own attacks more potent. It can also be used to bypass Devil Fruit defenses, such as the intangibility of a Logia. A person can apply the armament to a section of their body, over their entire body, and even imbue it onto their weapons. A coating of Armament Haki will cause the coated area to turn a shiny black, and a particularly thick and powerful coating will have a flame-like pattern along its edge. An advanced level of Armament Haki allows the user to emit the armament a short distance without a medium. A higher grade of advanced Armament Haki allows the user to make the emitted armament flow into a target's body and destroy it from the inside-out.

Supreme King Haki (覇王色の覇気, Haōshoku no Haki?), which grants the user the ability to unleash their own willpower in order to overpower the will of others. This results in victims being mentally overwhelmed by the user, with particularly weak-willed foes instantly losing consciousness. It can also apply pressure onto objects and damage them, a clash between two particularly strong Supreme King Haki users is capable of "splitting the heavens". Unlike the other types of Haki which can be learned by anyone, Supreme King Haki is a rare ability that only one in several million people are born with the ability to use. An advanced level of Supreme King Haki allows the user to infuse their conquering spirit into their weapons and physical attacks, greatly augmenting their power. Only a small handful of the most powerful Supreme King Haki users are able to achieve this. Another advanced level of Supreme King Haki allows for the ability to manipulate one's aura or presence, which negates an opponent's ability to sense the user with Observation Haki. Most people who can use Haki tend to have one type that they are better at, and, as a result, focus on training and fighting with that type primarily. However, a person can improve their abilities with all the types of Haki, it just requires more work. Each type of Haki has levels of usage, so even two proficient users might not be of equal strength. Furthermore, it is possible to use at least two types of Haki simultaneously.

Luffy and Zoro can use all three types of Haki while Sanji and Jinbē can only use both Observation and Armament Haki, and Usopp is the only other Straw Hat Pirate that can use Observation haki. The other Straw Hats can't use any type of Haki.

The standard Den Den Mushi is roughly the size of an ordinary house cat, with the dialing mechanism and receiver built into its shell (or, in rarer cases, a completely separate device "plugged" into the back of its head). Specimens vary widely in color and shell patterns and are often customized to signify their owners. The Marines, for instance, stamp their emblem on the shells of their Den Den Mushi. Due to their size, Den Den Mushi are typically left stationary on desks and the like. However, many have improvised methods to carry them and their accompanying accessories in times of necessity. On receiving a signal, a Den Den Mushi will make a purururu (プルルル?) sound indicates that the snails are actually pronouncing these "rings" phonetically (and very dryly), rather than making any noise akin to a genuine ring. Similarly, it will make a click sound when the receiver is removed or replaced. When a number is being dialed, the snail says beeps and boops. Den Den Mushi appear to have a separate signal for S.O.S. calls, which cause them to weep and cry loudly when they receive it. However, the recipient of the call does not get any information about the situation unless they actually pick up and talk to the person sending the signal. According to Nico Robin, the Marines are known for tracing calls by sending false alerts.

During active use, a Den Den Mushi will relay not only the speaker's words and emotions (laughter, screams, etc.), but also distinctive facial traits and even injuries. Depending on its mood, it can choose to disguise itself or mimic the traits of anyone close to it, either the one speaking or its owner. It is also possible for two specimens to converse with each other using a third party. Furthermore, they do not just pick up signals from each other, as they can send and receive signals from Smart Tanishi as well as receive warning signals from Territorial Sea Slugs. They are also capable of relaying nearby sounds, such as gunshots or broken glass. Den Den Mushi are very lethargic by nature, usually sleeping whenever not in use (and in some cases falling asleep mere seconds after a call ends). While Den Den Mushi have never been seen to change locations by their own will, Shaka implies they can move when he speculates that Egghead's Cameko could have moved from their post. The extent of their sapience is unclear, however they have been shown to take orders. In extreme situations, they are capable of emotions such as fear and gratitude. Den Den Mushi do have a "silent" mode. This is normally activated with a simple "shh" and a head nod. However, as they are living creatures, they have to be trained to access this ability. The resulting volume depends on the effectiveness of their training and their diet.

Den Den Mushi signals are susceptible being to tapped using a Black Den Den Mushi. Aramaki was shown to have a means of not only tapping the signals, but also override them, allowing him to speak through at least one of the connected Den Den Mushi. Upon being hijacked a Den Den Mushi will make an electrical buzzing noise. Den Den Mushi can be prevented from sending signals long distances via Doflamingo's Bird Cage ability, Impel Down's communication was also cut by Shiryu, the method by which this was done is unknown. Horned Den Den Mushi can be used to completely jam all Den Den Mushi signals within an unspecified area. When the Straw Hat Pirates took control of the Ryugu Palace during the Fish-Man Island Arc, the guards stationed at the kingdoms gate had not received any communication from the palace and theorized that the snail might be sick. This means that Den Den Mushi are capable of getting sick and that an illness could interfere with their ability to communicate. As living creatures, it is possible to knock them out using Supreme King Haki. In the anime, during the Summit War of Marineford, Buggy and the escaped prisoners from Impel Down thawed out a Den Den Mushi that had been frozen in Aokiji's ice by dipping it in seawater that had been made boiling hot by Akainu's magma, which resulted in the snail getting shriveled up by the salt water. However, Fukaboshi was later seen using a Den Den Mushi deep in the ocean without any ill effects to the snail.
