Boa Sandersonia

Boa Sandersonia (ボア・サンダーソニア) 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 the elder sister of Boa Marigold.

Appearance
Sandersonia is a large woman who resembles a snake. Her large head is shaped like that of a snake's and her tongue is forked. Like the rest of the Kuja, she dresses in very revealing clothing. She is usually seen accompanied with a large panther at her side instead of a snake like the other Kuja. On her back, covered by her cape and her long hair, is supposedly a set of eyes she and her sisters received after defeating the Gorgon.

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. Supposedly Sandersonia and her sisters have a set of eyes on their backs as part of a curse placed upon them for slaying the Gorgon. These eyes supposedly turn anyone who sees them into stone. Unfortunately, due to a little incident in which Luffy saw the back of Sandersonia's sister, Hancock, without turning into stone, it is unknown if this curse is really true.

History
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 Shichibukai meeting in which Hancock lied about attending, Sandersonia 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, Sandersonia and the rest of the pirates took the stuff they stole from the Marines and returned to Amazon Lily.

Trivia

 * Her name comes from the flower Sandersonia.
 * 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.
