Shari Shari no Mi

The Shari Shari no Mi, 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 Sharinguru.

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 resilient to the user's attacks, meaning that the spinning velocities of these wheels are not extremely powerful.

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

Anime and Manga Differences
While Sharinguru was seen in the battle with Franky in the anime, his Devil Fruit powers weren't shown as he instead attacked Franky with a sword.

Trivia

 * Excluding the SBS Devil Fruits, this is the only Manga-exclusive Devil Fruit Power.
