Fuwa Fuwa no Mi

The Fuwa Fuwa no Mi is a Paramecia Devil Fruit eaten by Shiki. It allows him to levitate things, such as battleships and himself. fuwa means "friction" in japanese.

Strengths and Weaknesses
The primary strength of this fruit lies in self-levitation. By levitating himself, Shiki can take flight. This proves to be helpful as he had severed his legs to escape Impel Down, and with his prosthetic legs, his swords Outou and Kogarashi, he would have trouble standing straight without this power of levitation.

Other than that, the user is still affected by the standard Devil Fruit weaknesses.

Usage
The abilities of this Devil Fruit allows Shiki the power to levitate nearby objects, including ones as big as battleships. When used on himself, he can fly, which would give him a great advantage in combat, which would theoretically enable him to avoid many different kinds of attacks with relative ease.

In addition, he has also used this Devil Fruit's power to manipulate the surrounding environment, such as fashioning stone debris and snow and wind into roaring lion heads.
