Her attire changes frequently. When first introduced, she wore a revealing red blouse that showed much of her chest and a loose sarong that exposed her long, slender legs with the green symbol of the Kuja adorned on it, along with a white cape sporting epaulettes more commonly found on the jackets of high-ranking Marines, and red high heel pumps. She then wore a qipao with a hooded cloak which she used it to cover Luffy until they arrived at Impel Down and then took it off during the battle against Whitebeard. During the Whitebeard War, she wore a purple dress with Kuja designs on it and purple high heel pumps. Upon her return to Amazon Lily, she reverted to her original outfit (with the exception of her cape). In all her outfits, she has worn a pair of golden that resemble snakes and high-heeled shoes; her attire is also adorned with the emblem of the Kuja, with an exception of when Hancock fell ill due to her Love Sickness, during which she wore a red blouse. After the timeskip, her attire looks the same as when she was first introduced, except it is colored blue (although it remains red in the anime).
Her beauty is noted by many throughout the world: to one of the Risky Brothers, her beauty is second only to that of the mermaids, while others like Marguerite and Hannyabal claim she is the most beautiful woman in the world. She is also almost always seen with Salome, her large Snake Weapon, which, despite the skull it wears, is usually smiling.
Despite Hancock normally looking either calmly beautiful or cute (in an attempt to "apologize" for her actions), when she is angered, she looks very intimidating, with her eyes bulging madly and her teeth bared, as seen when Smoker nearly killed Luffy.
Before Hancock fell in love with Luffy, and when she is not around Luffy, her eyes tend to look emotionless, but when she is around Luffy, her eyes show much more emotion, making her look like a girl in love.
Along with her sisters, on her back is the slave mark of the Celestial Dragon, something that she was so intent on keeping secret and was willing to petrify anyone (other than her sisters and Elder Nyon) who saw it. In order to make sure it was never seen, she and her sisters concocted a lie that what was really on the sisters' backs were pairs of Gorgon eyes which would petrify anyone who sets eyes on them. Hancock uses this "curse" as an excuse for her and her sisters' Devil Fruit abilities.
As a young child, she looked similar to how she does now, only her side-locks went past her shoulders and were worn in beads. During her escape from Mariejois, she wore rags and tied her hair in pigtails.
In Volume 63, SBS Oda drew the Shichibukai as children. Hancock is shown wearing a small laced top with exotic swirl patterns leaving her mid-riff exposed. Her only other piece of clothing is a small loin cloth around her hips.
Hancock is a very complex woman. At first glance, she appears to be selfish, pompous, spoiled, and used to having her own way. She can also act arrogant and cruel, usually justifying her less-than-admirable actions with her apparently unmatched beauty, causing her to think that she can get away with anything because the world will forgive her (and save for the handful able to resist she is largely successful in this approach, with gleeful suitors of both genders happily forgiving her every transgression). She also made it seem that she did not think much of the Kuja tribe either as she commented to Elder Nyon that she did not care if the island was destroyed or not, since everyone would forgive her anyway because she is beautiful.
Because of her beauty and strength, she is used to seeing men and women, young and old alike, fall instantly in love with her. As a result, people forgive her when she acts cutely apologetic or reminds them of her beauty. However, when Luffy came along and displayed a complete immunity to her charms, she initially felt that she could not bear the existence of someone completely invulnerable to her powers, and would collapse dramatically whenever insulted.
This feeling has eroded away, though, as she loves Luffy despite his immunity to her. Even after the two year timeskip, Hancock continues to be in love with Luffy as much as before despite that the latter openly rejected a wedding proposal from her.
It was revealed the reason for Hancock's lies and attitude towards life was that because of her horrible past, she did not want to ever show weakness again to anyone. She harbored a great fear of getting close to anyone, other than her own sisters, and would even go as far to deceive all of the other Kuja. This caused her surrogate mother, Elder Nyon, to fear that Hancock had truly turned as cold as ice. It wasn't until Hancock confessed everything to Luffy that she finally showed emotion, breaking down in tears after reliving her painful memories.
Deep down, Hancock is a rather-sensitive and vulnerable woman who is afraid and concerned about how other people (especially the other Kuja) might react to the truth of the shameful past that she and her sisters share. She is also much more soft and compassionate towards others when she opens up. That part of her was only first shown for the first time in several years in front of Monkey D. Luffy and she has not only befriended but also fallen in love with Luffy, even agreeing to venture to the land of her suffering, from her days of a slave, at his request for his brother.
Hancock has also shown to be very sly and crafty when the situation demands it. This was particularly evident when she aided Monkey D. Luffy into discreetly breaking through Impel Down's outer defenses, as well as manipulating the great prison warden, Magellan, to her whims before relaying a secret message to Luffy's brother Ace, whom Luffy was trying to rescue. She has also proven to be a very skilled liar who is excellent at fabricating stories, and her confidence leads her to never consider the consequences of her actions. An example of this is when she takes advantage of her beauty in Impel Down floor 6 to drive the prisoners mad, making them disrespect Magellan and causing enough trouble to speak to Ace freely without anyone noticing.
All of her arrogance seems to vanish when Luffy is on her mind, though. Whenever he is in her presence, she is quick to turn shy, barely able to meet him in the eye and gleaming over every action he takes. Even when he is not nearby, merely thinking of him causes her to blush and truly smile in a way that the other Kuja have said is unusual of her.
Despite the conceit she shows to her enemies and the facade she puts on for her people, she does show genuine care for people close to her. This was seen when she flew into a fit of rage and kicked Smoker away from Luffy after he had tried to kill him. Ignoring the possible consequences of her actions, she openly and publicly declared Luffy to be her beloved, effectively choosing her love over her title (and her people's treaty). During her fury, she showed none of her usual calm arrogance. This is seen again, to a lesser extent, when she screams at Aokiji for stabbing Luffy with an Ice Saber. Her anger is enough to make even Jinbe to cower in fear, albeit slightly and in a comedic manner.
Hancock's time with Luffy has changed her personality considerably since from before. She has now started to treat others, even some men, with much more kindness and respect. She has come to understand that not all men are the same and even allowed Law and his crew to dock at the edge of her island and choose to lift her countries law's somewhat. She has also started to treat her fellow Kuja's with much more kindness and respect and has even decided to do work with them such as help them make food for Luffy rather than just order them around as usual. Nyon and even her sisters have become amazed how much she's changed ever since she fell in love with Luffy.
While referring herself, Hancock uses "warawa wa" (ワラワ?) — an antiquated pronoun that signifies nobility — instead of the more common "watashi wa" (私は? literally meaning "I am").
Hancock has several running gags. The first is that when she looks down on people, she leans backwards so she faces the ceiling (or the sky) above her, apparently looking down on people so much she's looking up.
Another is that she appears to dislike small animals, in which she angrily asks who left the animal in front of where she's walking before kicking it away, no matter how cute it is. A Kuja responsibly apologizes, while the offended animal snarls at her, and Hancock advises her to be more careful in the future. Lastly, she often thinks about Luffy and mistakenly thinks that they are married or engaged.
Hancock is widely considered to be extremely powerful by friend and foe alike. Ruling beside her sisters, Hancock has power over Amazon Lily and the rest of the Kuja tribe. As the empress and captain of the tribe, she is most likely the strongest Kuja warrior. The Kuja believe that "strength is beauty", and since all members of the tribe state that she is the most beautiful in the world, they believe she is very powerful, and the strongest among the entire tribe. It is to be noted that only the strongest Kuja warriors are allowed in the country's pirate crew, Hancock and her sisters were strong enough to be there when they were small children, although it is possible they were just apprentices like Shanks and Buggy.
Her strength is so great that it has even been acknowledged by the Fleet Admiral of the time, Sengoku of the Marines. Even former Admiral Kuzan commented on her skills, stating she is not to be underestimated. Further testament to her strength is how she was one of the three Shichibukai who managed to leave the war without sustaining any injuries. The fact that she can earn a Beli80,000,000 bounty after her first campaign as a pirate further supports her capabilities.
This is shown when she had managed to destroy several Pacifistas single handedly (by petrifying beforehand the incredibly tough alloy of which they are composed of) without showing signs of exhaustion or injury, where it took the whole Straw Hat crew (before their two-year training) to take down just one, which left them severely worn out. While it is true that the Pacifistas were programmed not to attack their allies, to destroy so many of them is a difficult task regardless.
Hancock is quite skilled in the arts of subterfuge and deception, managing to disguise Luffy inside her coat without eliciting much suspicion across an entire boat voyage and inside Impel Down, as well as being the sister to propose spreading the tale of the "Gorgon curse" to prevent her subordinates from discovering the humiliating brand of enslavement on their backs over a period of decades. Hancock is also very intelligent, sly, and crafty when the situation demands it, being able to buy Luffy time, using her charms, after overhearing Magellan's plan to halt his infiltration and managed to manipulate events on Level Six of Impel Down by creating a commotion between the residing prisoners and a "protective" Magellan to speak to Portgas D. Ace in private and not attract any attention, as well as stealing the key to Ace's handcuffs for Luffy prior to his arrival, knowing it would be useful. Hancock is also very skilled at utilizing her beauty and charm to get whatever she wants. With only Luffy as an exception, both men and women have been shown to be susceptible to her charms which therefore allows her to manipulate people as she desires. Her claim that she's able to get away with anything because she is beautiful has so far been shown to be true, with her antagonistic actions during the Marineford war seemingly unnoticed despite her openly attacking Marines and declaring her love for Luffy. In Impel Down, she used her charms to convince Magellan to take her down to Level 6 in order to buy Luffy more time, and at Level 6, she used her charms once more to cause a ruckus in order to pass a message to Ace.
She has been shown to be extremely adept in hand-to-hand combat, often in tandem with her Devil Fruit abilities. She was able to fight through many of the New World pirates effortlessly. Similar to Sanji's fighting style, Hancock seems to prefer kicking-based attacks, whether from kicking in-the-way cute animals or her enemies. Though she's stronger in short-range combat, Hancock is also adept in long-range and is capable of using her Devil Fruit powers to strike her enemies from a long distance.
Her raw strength is immense, obviously showing signs of super-human strength as she can easily break stone (in the form of petrified opponents) with a single kick, capable of breaking several Pacifistas without breaking a sweat (while Sanji nearly broke his leg attempting the same task, though she used her Mero Mero no Mi powers to turn them into stone first) and being able to kick Smoker in his smoke state with her Haki; although with all those examples, she could have been using Busoshoku Haki to strengthen her kicks.
