Moku Moku no Mi

The Moku Moku no Mi (Smoke Smoke Fruit in the English dub, Plume Plume Fruit in the English Manga) is a Logia-type Devil Fruit, eaten by Captain Smoker.

This fruit allows the user to transform into smoke at will, as well as control it.

"Mokumoku" means silent, and "moku" is an anagram of "kumo", which means "cloud", "moku" is also the sound billowing smoke makes.

Strength

As all logia users physical blow will pass through the user. Also the user is able to increase the density of the smoke and thus is able to grasp objects, this seems to be the primary way captain smoker catches pirates

Weaknesses

Besides the inability to swim there has not been any other specific weakness; however it has been hinted that strong winds may be a weakness.
