Dehydration

Like Caesar; Crocodile is a One Piece logia and so is intangible.

Now being a Logia doesn't automatically put Crocodile on this list; what does is his Barján and Desert Encierro. Both attacks are able to fatally dehydrate his enemy. Crocodile's dehydration is absolute; able to turn stone into sand by dehydration alone.

Yeah Mr. 3 survived this attack, but Crocodile wanted to execute him 'Dr. Evil' style with a crocodile (the animal, not the man) and forgot that Mr. 3 is relatively smart and has the ability to make steel-hard barriers. So I'm considering that Crocodile isn't acting like an idiot again.
