Sir Crocodile

Suna Suna no Mi ; Sand Sand Fruit
Sir Crocodile
Allows the user to create, absorb, manipulate, and turn into sand. Its power can be honed to the point where the user can also dry anything he or she grasps, killing the living through dehydration, and causing all other matter to crumble to dust. However, Crocodile turns solid when in contact with any liquid, including blood (or sweat in the English dub), due to the sand sticking together.

"Suna" means "sand".
