Snake Weapon

The Kuja all have snakes which can be used as weapons or other things. When not in use, the snakes wrap themselves around the body of the Kuja who own them. The serpents' bodies are about as long as the Kuja who use them; the exception being Salome, Hancock's snake, whose body is exceptionally long compared to the others. Also, they all wear small berets and a scarf, with the exception of Salome, who wears a skull on its head and appears to have some form of furry scarf around its neck instead of a normal cloth one.

When the snakes form into their various shapes, no word is spoken by the Kuja (as seen so far) to instruct the snake to form the shape it does. How the snakes know which form to take is uncertain. They are also useful for tracking people and animals, as Hancock used her snake to find Luffy after the war.

Shapes

 * Bow: The first mode of the Snake Weapon used by the Kuja. The snakes form a bow shape position with strings behind them. They are capable of firing projectiles such as arrows like normal bows. The arrows fired by the snakes are imbued with Busōshoku Haki, increasing the force of impact.


 * Staff: Nyon's snake is seen in the formation of a staff, however it has not been seen for battle use. In Chapter 521, however, it has also been used as a stepladder for the small sized elder to speak with Boa Hancock, her sisters and Luffy.


 * Chair: Boa Hancock was seen using her oversized snake, Salome, as a throne in her bed.


 * Ropes: Small snakes are used to tie up Luffy. Luffy states the snakes are as strong as steel.


 * Corkscrew: Boa Hancock's large snake took the form of a spiral, elevating her above the battlefield. Though it had no attacking value it took her out of harms way, from which she could speak to and look down at the Marines much easier.
