Talk:Crocodile vs. Toph Beifong/@comment-35099927-20180325035852/@comment-31067519-20180325051126

I think Crocodile could figure out Toph's seismic sense, or at the very least that she needs her feet and hands to earthbend since she's clearly blind. One big part about earthbending, and elemental bending in general, is that users have to move their limbs intricately in certain ways to get their element to move the way they want it. Most Devil Fruit users, however, don't need to since it's a natural part of their being, such as Magellan manipulating his poison hydras or Mr. 3 making a dense candle wax wall just by literally standing there. A few Devil Fruits do require some bodily movement, such as Cracker needing to clap his hands to produce more biscuits, but not to the same extent that benders do. Something that someone as intelligent and experienced as Crocodile probably knows.

If Crocodile noticed the bandages on the strawhats' arms and quickly deduced they were a safeguard against Mr. 2's/Bentham's appearance-copying Devil Fruit, there's a high chance that at the very least he'd notice that Toph moves her arms and feet in a certain way every time she manipulates the ground along with the fact that she's clearly blind. He'd probably put two and two together and figure out that, at the very least, Toph needs her hands and feet to properly fight.
