4 – SUNA SUNA NO MI
The Suna Suna no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into sand at will, turning the user into a Sand Human. It was eaten by Crocodile.
This fruit is quite powerful, even among Logia, as it allows for a great variety of abilities, rather than just normal elemental control. It also allows the user to locate quicksand, set off sandstorms, and absorb liquids. This fruit allows Crocodile to sense anything that is moving through sand.
