Boa Marigold

Boa Marigold (ボア・マリーゴールド) is one of the three Gorgon sisters that rule over Amazon Lily. She and her sisters are called the Gorgon sisters for supposedly heroically slaying a monster called the Gorgon. She is the younger sister of Boa Hancock and Boa Sandersonia.

Appearance
When she was younger, Marigold was quite small and slim like her older sister. Now she is a large and fat woman. Her hair is arranged in a way that it looks like the patterns on a cobra's hood and to some extent, a Valkyrie's helmet. She is first seen accompanied with a large hawk at her side instead of a snake like the other Kuja. On her back, covered by her cape and her long hair, is believed by the Kuja, a set of eyes she and her sisters received as part of a curse for slaying the Gorgon. It is now known that the symbol on the Boa sisters' backs is the "Hoof of the Soaring Dragon," an emblem burned upon the slaves of the Tenryuubito.

Personality
Marigold is the stern one amongst the three sisters, who displays the least amount of emotions outside of battle. 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 hasn't actually told a lie herself unlike Hancock who is constantly lying.

In battle Marigold is an offensive warrior who is slightly playful (but not as playful as Sandersonia).

Abilities and Powers
Ruling beside her sisters, Marigold has power over Amazon Lily and the rest of the Kuja women. Being apart of her sister's pirate crew, she is one of the elite Kuja warriors. Also of the sisters, she the the only one that actually wield a weapon, in this case a spear.

She possess the ability to use Haki to defend and deflect against attacks, even against other Devil Fruit users. While she can do this, she can't block an opponent's attack if it is too strong for her, like Luffy's Gear Second attacks.

Devil Fruit
Marigold ate the Hebi Hebi no Mi, Model: King Cobra that allows her to turn into a King Cobra. While these powers are Zoan Devil Fruit based, the Kuja of the island attribute Marigold's and Sandersonia's ability to turn into snakes as part of the curse.

Shameful Past
Several years before the current storyline, when Marigold and her sisters were young, the three of them were captured by the slave traders while out on sea. They were sold off to some Tenryuubito and had their backs branded with the mark of slavery. As slaves of the Tenryuubito, they were horribly abused by their masters. As part of a cruel form of entertainment, Marigold and her sisters were fed Devil Fruits to amuse their masters. Living in this pitiful state, Marigold and her sisters could only think of dying. It was only until four years later, they were freed from this cruel life. A Fishman by the name of Fisher Tiger attacked Mariejois and freed the Fishmen slaves there. While Fisher Tiger hated humans, he also freed the human slaves which included Marigold and her sisters.

Not knowing how to return to Amazon Lily, Marigold and her sisters were fortunately able to return home thanks to a far from home Elder Nyon, who cared for the three girls like a mother. Thanks to having eaten the Devil Fruits while enslaved, Marigold and her sisters were able to come up with a story of them receiving a curse for slaying a monster called a Gorgon. This was all in order to cover the shameful marks on their backs from their fellow Kuja. Spreading this deception, they became Amazon Lily's rulers with her sister, Hancock, as the new Empress.

Secret Discovered and Battle against Luffy
On the way back to Amazon Lily after one of their pirating exploits, Marigold 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, Marigold accompanied her sisters in greeting the Vice Admiral. Despite the Vice Admiral's demands that Marigold's sister comply with the compulsory Shichibukai meeting in which Hancock lied about attending, Marigold joined in her sister's continued refusal to help the World Government in such a critical. After her sister turned all of Momonga's men to stone, Marigold and the rest of the pirates took the stuff they stole from the Marines and returned to Amazon Lily.

After having arrived back, Marigold and her sister Sandersonia set forth to guarding their elder sister from any roaming eyes as Hancock took a bath. Unfortunately, as Marigold and Sandersonia were guarding, Luffy accidentally crashed through the roof of the bath they were guarding. Coming into the bath to see what happened, Marigold and Sandersonia found out that this man had saw what was on their sister's back while she was bathing. Realizing that this man had discovered their secret, the three sisters decided that Luffy had to die. However despite Marigold's eldest sister's attempts to turn Luffy to stone, Luffy was unaffected. Knowing that no one could be immune to her sister's beauty regardless of age and gender, Sandersonia guessed that Luffy's fear of death might be overwhelming any wicked desires. Though Marigold and her sisters couldn't eliminate Luffy then and there, the man was still captured.

With Luffy captured and brought to the arena of Amazon Lily, Marigold accompanied her sisters to see this man 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 that accompanied Sandersonia's side, Bacura, was sent to devour Luffy. However despite her pet's ferociousness, Luffy beat him with sheer brute strength. After this and Luffy's continuing apparent refusal to her eldest sister's charms, Marigold accompanied with Sandersonia decided to take things into their own hands. Facing Luffy, Marigold and her sister turned into half snake women and prepared to attack this man in a act the other Kuja called Saragi Dance.

As Marigold 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 the Luffy's shout and seeing several Kuja warriors in the audience of the arena suddenly pass out, Marigold and her sisters realized that Luffy also possessed Haki whose caliber was on par with Hancock. Stunned by this revelation, Marigold and her sister Marigold watched as Luffy decided to fight them more seriously.

Having seen that their opponent was no ordinary man, Marigold and Sandersonia decided to fight against Luffy more seriously as well. Unfortunately, upon Luffy activating Gear Second, he proved too much for Marigold and her sister. In the middle of the fray, Sandersonia accidentally got caught on fire by her sister's technique. With her tail also tied to her sister's by Luffy, Sandersonia almost fell down to spiked pit around the arena while on fire. Though the fire was put out and she was able to reach the stands to prevent her from falling, the fire unfortunately burned all of her top clothing, including the cape that covered her back. With the cape burned, her long hair unable to cover her back due to her position, and the smoke clearing, Marigold 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 had the intention of allowing their deep secret being revealed. With Sandersonia's back covered, her sister, Hancock, ordered everyone to leave the arena.

Current Events (spoilers)
With their secret safe, Marigold's sister, Hancock, decided to reward Luffy for concealing it. However, Marigold's sister told that Luffy he could ask for one request, a ship or to turn Marguerite and the others back to normal. Much to Marigold and her sisters' surprise, Luffy asked for the latter. After the three Kuja warriors were reverted back to normal, Marigold and her sisters decided to discuss what Luffy saw on her elder sisters' back. Learning that Luffy mistook the symbol for the one on a fishman friend of his named Hatchan, they soon also learned from Elder Nyon that this man was Monkey D. Luffy, a pirate whose act of defiance against a Tenryuubito was reported in the news. Discovering about this, Marigold's sister decided to explain things to Luffy despite the horrible memories they held. Having explained things to Luffy, Marigold and her sisters learned that Luffy completely hated the Tenryuubito for their crimes. With this, Marigold's elder sister decided to lend Luffy their ship. Unfortunately, Marigold's elder sister, Hancock, was suddenly stricken by an untreatable illness. As she lay dying from the pain, Elder Nyon informed her that Luffy has a request. With that, Hancock ignored her ailment to hear Luffy's request. When he requested her to answer the call to fight the Whitebeard Pirates, but travel to Impel Down to save his brother: Portgas D. Ace, Marigold and Sandersonia were outraged that he would ask such a thing. Putting aside her illness, the two sisters perceived Luffy's request as absurd that after hearing their tragic tale, he would ask their empress and elder sister to return to the cursed "Holy Land" which caused them so much anguish and torment, and expected Hancock to turn Luffy into stone. However, to their surprise, not only did their elder sister accept Luffy's request, but her illness is revealed by Nyon to be "love sickness", which has killed the empresses before her: Hancock had fell in love with Luffy. With Boa Hancock returning to Vice Admiral Momonga's ship, Marigold and Sandersonia see their sister off, returning to Amazon Lily to rule in her stead, wishing Hancock the best of luck, and in their thoughts, hoping for Luffy to succeed, as the young pirate is hiding in Hancock's coat.

Trivia

 * Her name comes from the flower Marigold.
 * While Marigold 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.
