The Kaze Kaze no Mi is a Logia-type Devil Fruit that allows the user to control, manipulate, and create wind.
The fruit looks like a green Rowan berry with swirls on it.
The main strength of the Kaze Kaze no Mi, much like other Logia-type Fruits is the ability to shift into the element they control in order to avoid damage. Being able to control wind allows them to use the powerful element to blow their enemies away and cause vicious disasters with it. There appears to be no limit to how often they can use their Devil Fruit, because the wind is almost always surrounding them.
The weakness of the Fruit would probably stem from a lack of wind in the general area, so if the user were trapped in the Calm Belt or another area with no wind, they would only be able to use what their body has in reserve. Other than that, no other weaknesses are known and the same standard Devil Fruit weakness applies.
The user can create tornadoes, powerful gales, wind storms, and other forms of natural disasters involving wind with the use of their Devil Fruit.

Rumor and myth says that Monkey D. Dragon has the Kaze Kaze no Mi, but such a thing has not been stated in the official series yet, so no proof is given to support this statement.
