Salome

Salome is Boa Hancock's personal Snake Weapon.

Appearance
Salome is a large white snake with large pink spots running down its body. It wears a horned skull with a couple of cracks on top of its head, has blue hair jutting out from the back of the skull, and is usually seen with what appears to be a smile.

In the manga, Salome's skin was seen as a shade of pink that was lighter than the spots running down its body.

Abilities
As an oversized Snake Weapon, Salome usually curls itself into a chair for Hancock to sit on, similar to a throne. It also has curled itself as a spiral for supporting her.

It also has the ability to track down things on the ocean floor, shown when it was able to sense Whitebeard's seaquake before it arrived and when he helped Hancock follow Trafalgar Law's submarine.

History
Salome has been seen with Hancock since her debut, and has served as her throne when she sat in her room and in the coliseum. When Hancock answered the Marines' call to attend the Whitebeard War, she was permitted to bring Salome with her. Salome has served as a spiral support for Hancock during the war, and when Monkey D. Luffy broke down from Portgas D. Ace's death, Hancock confided to the snake how worried she is about Luffy.

After Luffy escapes Marineford with the aid of the Heart Pirates and their submarine, Hancock follows the submarine using Salome's tracking capabilities. After returning to Amazon Lily, Salome resumes the role of being Hancock's throne.

Trivia

 * In biblical text, Salome was the daughter of Herodias, who is often depicted as dangerous and seductive. As a note of coincidence, Salome's owner Hancock can be considered such a person.
