Shari Shari no Mi

The Shari Shari no Mi, also known as the Shari Shari Fruit, is a Paramecia type Devil Fruit that allows the user to transform their arms and feet into wheels. "Shari" means wheel in Japanese. It was eaten by Sharingu. It is not seen being used in the anime, as Sharingu attacks Franky with a sword instead.

Strengths and Weaknesses
The only strength of the fruit, so far seen, is that when the user turns his arms into wheels and spins them at a high speed, they gain formidable spinning weapons they apparently can use to attack their opponents. The fruit so far doesn't seem to have any specific weaknesses outside the standard Devil Fruit weaknesses, however, it appears that metallic like bodies, like Franky's arms, seem to be somewhat immune to the user's attacks.

Usage
The fruit's bestowed powers, as used by Sharingu, have so far been used primarily for combat. Sharingu has used the fruit's powers to turn his arms and feet into wheels in order to attack Franky.
