"Boa Sandersonia" has been featured, meaning it was chosen as an article of interest.

Boa Sandersonia[3] is the younger sister of Boa Hancock, the ruler of Amazon Lily. She is also one of the second-in commands of the Kuja Pirates and the older sister of Boa Marigold. She and her sisters are referred to by the Kuja as the Gorgon Sisters.[1]


Sandersonia is a large woman who resembles a snake, with a curvaceous figure and large breasts like her sisters. Her head is disproportionately large and wide to her body and her long tongue is forked, often sticking out of her mouth and has sea green eyes (amber in snake form).

Like the rest of the Kuja, she dresses in very revealing clothing: a green bikini top with white irregular patterns, a white cape over it and green panties encircled by flaps at both sides of her hips. She wears brown boots and a green stocking on her left leg with a design which resembles the Kuja Pirates' Jolly Roger.

She is usually seen accompanied by the large panther, Bacura, at her side instead of a snake like the other Kuja. Along with her sisters, her beauty is highly admired by the Amazon Lily islanders.[1] In her younger days, Sandersonia was an average height teen who wore orange skirt and green top.[5]

Sandersonia wore a tan bra that seems to be bandaged of some sort, after her clothes were burned during the fight against Monkey D. Luffy.

At Rusukaina, Sandersonia’s attire does not change, with the exception of her cape and the designs of her bikini, which take the form of snake scales.

On her back, covered by her cape and her long green hair, is a mark of slavery branded on her by their previous Celestial Dragon masters. It resembles a hoof mark and is a sign that means that she is "less than human" since she was a slave. Her sisters share this mark as well on their backs.[6][7]

Sandersonia appears very fond of her sister Hancock, as noted by the fact she laughed at her sister's "twisted" personality. While she appears to be living on the lie that her sisters and herself defeated a Gorgon to gain their curse, at the same time, she has not actually told a lie herself, unlike Hancock who is constantly lying. Sandersonia is the most emotional of the 3 sisters and highly emotional about their horrible past, her crying had to be eased by her sister Marigold and drove her to collapse onto the floor.

Due to her slave brand's shameful meaning, Sandersonia and her sisters made their fellow Kuja believe that on their backs were a set of eyes she and her sisters received as part of a curse for slaying the Gorgon. They told them that these eyes turned anyone who sees them into stone. If any of the Kuja found out the truth, Sandersonia and her sisters would be forced to leave the island.

In battle, Sandersonia is a playful warrior who teases and torments her victims before she crushes them. However, she is prone to underestimating her opponents, as seen by Luffy using second gear and Haōshoku Haki.



Hancock and Marigold[]

Sandersonia is close with her sisters Boa Hancock and Boa Marigold. Having experienced the same cruel treatment by the hands of the World Nobles, they protect the secret on their backs from anyone, including the various islanders of Amazon Lily. After the Marines and Blackbeard's invasion, Hancock would endanger Sandersonia and Marigold's lives if she stays at Amazon Lily when she decided to leave and reunite with Luffy in order to protect her little sisters.


Unlike her sister Hancock, Sandersonia has respects for Gloriosa and owe her a debt for taking her and her sisters back home after escaping the World Noble.



As the previous empress who is one of her sister's predecessors, Sandersonia has a strong respects for Shakuyaku. Shakuyaku hidden Sandersonia and her sisters from the World Nobles and sent them back home. Sandersonia claimed that Shakky for Rayleigh about Hancock's love and devotion for Luffy. After her sister Hancock lost her title as a Warlord, Shakky and Rayleigh arrived at Amazon Lily to aid Sandersonia and the Kujas as well as drove both the Marines and the Blackbeard Pirates out. Shakky advised Sandersonia and her sisters about Vegapunk's latest invention and tells that Calm Belt is no longer safe as long as Hancock stays. When Hancock decided to leave Amazon Lily for her reunion with Luffy, Shakky was entrusted of guarding Sandersonia, the Kujas and Amazon Lily while Hancock is away.

Silvers Rayleigh[]

Sandersonia is good friends with Silvers Rayleigh since he helped shelter her and her sisters after they escaped from the World Nobles. After Ace's death, Sandersonia and her sisters reunited with Rayleigh. After her sister Hancock lost her title as a Warlord, Sandersonia and the others were saved by Rayleigh and his wife, former empress Shakuyaku. When Hancock decided to leave Amazon Lily for her reunion with Luffy, Sandersonia and the other Kujas are under the protection of Rayleigh.

Monkey D. Luffy[]

Sandersonia originally was antagonistic towards Monkey D. Luffy, as seen in their battle. However, she was amazed at his ability to use Haoshoku Haki but this didn't change her mind until he protected her and her sisters by covering her slave mark before it was exposed to the other Kujas. Sandersonia came to respect Luffy after he requested for the three Kujas to be turned back from stone than being selfish, learning that he struck a World Noble, and when he showed no scorn towards the Gorgon Sisters for being former slaves. After Luffy requested Hancock to help him rescue his brother Ace, Sandersonia and Marigold were both angry at him until Hancock accepted his wish, leaving those two shocked.


World Government[]

Like her sisters Hancock and Marigold, Sandersonia considers the World Government as an enemy due to her and her sisters being slaves of the World Nobles.

Abilities and Powers[]

Ruling beside her sisters, Sandersonia has power over Amazon Lily and the rest of the Kuja women. Being a part of her sister's pirate crew, she is one of the elite Kuja warriors.[8] She can also control her hair and shape them into snakes for increased attack strength.[9]

She is shown to have a strong will, being able to resist Luffy's Haoshoku Haki.[10]

Devil Fruit[]

Further information: Hebi Hebi no Mi, Model: Anaconda
Hebi Hebi no Mi, Model Anaconda Infobox

Hebi Hebi no Mi, Model: Anaconda.

While she was a slave of the World Nobles, Sandersonia and her sisters were force-fed Devil Fruits as a form of sick entertainment.

Sandersonia ate the Hebi Hebi no Mi, Model: Anaconda, a Zoan-type Devil Fruit that allows her to transform into an anaconda.[11] She can bind and strike at her opponents with her tail, and her long flexible body can easily bend out of the way of her opponents' attacks.

She can also shape her hair into a number of snakes. The fangs of her hair snakes are strong as steel.


Further information: Haki

Busoshoku Haki[]

Sandersonia can use Busoshoku Haki since she was able to physically harm Luffy despite him being rubber.[12]

Kenbunshoku Haki[]

Snake Dance

Sandersonia using Kenbunshoku Haki to dodge.

Sandersonia is able to read an opponent's movements and avoid their attacks using Kenbunshoku Haki, having mastered it to a point she can seamlessly dodge attacks at high speed.[12] However, it is useless if said opponent is drastically faster than she is, such as Luffy in Gear 2.[13]


Shameful Past[]

Twenty four years ago, Sandersonia was seen commenting on the coming Great age of piracy with her sisters Hancock and Marigold[14]. Seventeen years ago, when the Gorgon Sisters were young, they were captured by slave traders while out at sea, were sold off to some World Nobles, and had their backs branded with the mark of slavery. As slaves, they were horribly abused by their masters, and as part of a cruel form of entertainment, were fed Devil Fruits to amuse their masters. Living in this pitiful state, Sandersonia and her sisters could only think of dying.

Gorgon Sisters Escape Mary Geoise

The "Gorgon" sisters freed from Mary Geoise by Fisher Tiger.

Four years later, they were freed from this cruel life by the fish-man Fisher Tiger, who attacked Mary Geoise and freed the fish-men slaves there. While Fisher Tiger hated humans, he did not discriminate within slaves and also freed the human slaves, which included Sandersonia and her sisters.[15]

Not knowing how to return to Amazon Lily, Sandersonia and her sisters were fortunately able to return home thanks to Silvers Rayleigh, Shakuyaku, and a far-from-home Elder Nyon. The latter of the three cared for the three girls like a mother.[16]

Thanks to having eaten the Devil Fruits while enslaved, Sandersonia and her sisters were able to come up with a story of them receiving a curse for slaying a monster called a Gorgon.[17] This was all in order to cover the shameful marks on their backs from their fellow Kuja.[18] Spreading this deception, they became Amazon Lily's rulers with her sister, Hancock, as the new empress.

Accompanying her elder sister in a pirating campaign, Sandersonia and the other Kuja Pirates soon caught the attention of the World Government. Knowing how much power they had, the government signed a treaty with the Kuja and gave Sandersonia's sister, Hancock, the title of Warlord of the Sea.

Summit War Saga[]

Amazon Lily Arc[]

On the way back to Amazon Lily after one of their pirating exploits, Sandersonia and the rest of the Kuja Pirates encountered the Marine Vice Admiral Momonga and his men anchored in the middle of the Calm Belt. Heeding his calls for Hancock to come before him, Sandersonia accompanied her sisters in greeting the Vice Admiral. Despite the Vice Admiral's demands that Sandersonia's sister comply with the compulsory Seven Warlords meeting, which Hancock lied about attending, Sandersonia joined in her sister's continued refusal to help the World Government in such a critical juncture. After her sister turned all of Momonga's men to stone, Sandersonia and the rest of the pirates looted the ship and returned to Amazon Lily.[19]

After having arrived back, Sandersonia and her sister Marigold set forth to guard Hancock from any roaming eyes as she took a bath. Unfortunately, as Sandersonia and Marigold were guarding her, Luffy accidentally crashed through the roof of the bath.[20] Coming into the bath to see what happened, Sandersonia and Marigold found out that this man had seen what was on Hancock's back while she was bathing.

Realizing he had discovered their secret, the three sisters decided that Luffy had to die. Hancock attempted to turn him to stone, but he was unaffected. Knowing that no one could be immune to her sister's beauty regardless of age and gender, Sandersonia guessed that his fear of death might be overwhelming any wicked desires. Though Sandersonia and her sisters could not eliminate him then and there, they still managed to capture him.

With Luffy captured and brought to the arena of Amazon Lily, Sandersonia accompanied her sisters to see him be executed along with the rest of their subjects. After her sister turned three Kuja warriors to stone for rescuing Luffy from some mushrooms, the panther Bacura was sent to devour Luffy. However, despite the pet's ferociousness, Luffy beat it with sheer brute strength.

Saragi no Mai

The Gorgon sisters surround Luffy.

After this, and Luffy's apparent continuing obliviousness to their elder sister's charms, Sandersonia and Marigold decided to take matters into their own hands. Facing Luffy, Sandersonia and her sister turned into snake-human hybrids and prepared to attack him with a technique the other Kuja called Saragi Dance.[21]

As Sandersonia and her sister battled against Luffy, they decided to torment him by breaking Marguerite, one of the Kuja warriors who saved him, into pieces before his eyes. However just as Sandersonia was about to break Marguerite, Luffy shouted loudly at them to stop. Feeling the force from Luffy's shout and seeing several Kuja warriors in the audience suddenly pass out, Sandersonia and her sisters realized that Luffy also possessed Haoshoku Haki, and his caliber was on par with Hancock's. Stunned by this revelation, Sandersonia and Marigold watched as Luffy decided to fight them more seriously.[22]

Having seen that their opponent was no ordinary man, Sandersonia and Marigold decided to fight against Luffy more seriously as well. Unfortunately, upon Luffy activating Gear 2, he proved too much for Sandersonia and her sister. In the middle of the fray, Sandersonia accidentally got caught on fire by her one of her sister's techniques. With her tail also tied to her sister's by Luffy, Sandersonia almost fell into the spiked pit around the arena while on fire. Though the fire was put out and she was able to reach the stands to prevent herself from falling, the fire unfortunately burned off all of her clothing, including the cape that covered her back.

Sandersonia Protected

Luffy covers Sandersonia's back.

With the cape burned, her long hair unable to cover her back due to her position, and the smoke clearing, Sandersonia and her sisters' secret was about to be exposed. However, before anyone of the Kuja in the audience could see her back, Luffy covered Sandersonia. Wondering what he was doing, Luffy explained to Sandersonia that despite the fact that she and her sisters were trying to kill him, he had no intention of killing them nor did he have the intention of allowing their deepest secret to be revealed. With Sandersonia's back covered, her sister, Hancock, ordered everyone to leave the arena.[23] With their secret safe, Hancock, decided to reward Luffy for concealing it. However, Hancock told that Luffy he could ask for one request, a ship or to turn Marguerite and the others back to normal. Much to the Gorgon Sisters' surprise, Luffy asked for the latter.

After Sandersonia and Marigold reverted to normal, the Gorgon Sisters decided to discuss what Luffy saw on Hancock's back. Learning that Luffy mistook the symbol for the one on his fish-man friend Hatchan, they soon also learned from Elder Nyon that this man was Monkey D. Luffy, a pirate whose act of defiance against a World Noble was reported in the news. Discovering this, Hancock decided to reveal her past to Luffy despite the horrible memories it held. Having explained everything to Luffy, the Gorgon Sisters learned that Luffy completely hated the Celestial Dragons for their crimes. With this, Hancock decided to lend Luffy their ship.[6]

With Hancock deciding to help Luffy, the pirate was soon accepted within the community of the island. However, despite the festivities celebrated around Luffy, a more important matter soon arose that caught Sandersonia's attention. Hancock had started to behave strangely. Not knowing what was happening to her, Sandersonia and everyone else who tended to Hancock's side thought she had contracted a disease. When news of Hancock's condition reached Elder Nyon, the old woman apparently confirmed their suspicions and told them that it was something the previous empresses of Amazon Lily had died of. As all this was happening, Elder Nyon told Hancock that Luffy wanted to talk to her. Despite her condition, Hancock decided to talk to Luffy alone.[24]

Hiding alongside Marigold so they could eavesdrop, Sandersonia learned what Luffy wanted. It turned out that Portgas D. Ace, the one was to be executed by the World Government, was actually Luffy's older brother. The pirate asked Hancock to answer the compulsory Seven Warlords call so he could join her and sneak into Impel Down where Ace was being held before his execution. Hearing this request, Sandersonia and Marigold were deeply outraged by what Luffy was asking. Knowing how painful it was emotionally to return to the cursed "Holy Land", the two of them were expecting their sister to turn Luffy into stone for asking such a thing. However much to their surprise, their sister accepted Luffy's request while blushing. It was then that Elder Nyon revealed to them that the disease that their sister had contracted was actually "love sickness".

With her sister's decision, Sandersonia and the rest of the Kuja Pirates saw Boa Hancock and her snake off to Momonga's ship along with Luffy hiding in her coat. With their sister going to Mary Geoise, Sandersonia and Marigold promised Hancock that they would take care of Amazon Lily in her stead.[25]

Rayleigh Meets With Sandersonia, Marigold and Gloriosa

Sandersonia, Marigold, and Nyon reunite with Rayleigh.

After the war between the Whitebeard Pirates and the Marines, Hancock came back to Amazon Lily along with several men, most notably a heavily injured Luffy. As not to set a bad example, Hancock was forbidden to see Luffy until he was fully recovered. The situation however did cause both Sandersonia and Marigold some concern over their elder sister as Hancock had refused to eat anything since her return.[26]

After some time, Sandersonia went with her sisters and Nyon to give Luffy some food. Upon reaching the rendezvous point, they meet and got reacquainted with Rayleigh who had just arrived on the island to offer Luffy something.[27]

She was present on the Kuja ship that brought Luffy to Rusukaina.[28]

  • Sandersonia's favorite food is xiaolongbao.[3]
  • Sandersonia's name comes from the flower Sandersonia aurantiaca. The head of each Sandersonia flower is large and bulb-like, much like the shape of Sandersonia's own head.
  • While Sandersonia and her sisters' title, the Gorgon Sisters, comes from supposedly slaying a monster with the same name, their concept is loosely based on the three actual mythological Gorgon sisters which includes the famous Medusa. Sandersonia is also able to convert her hair into snakes; snake-hair was another gorgon trait.
    • As the middle sister, she can be considered the equivalent to Euryale, who is noted for her bellowing cries. Sandersonia is the most emotional among the sisters and cried out upon reminiscing about their horrific past.
