Gasu Gasu no Mi

The Gasu Gasu no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into gas at will, turning the user into a Gas Human (ガス人間). "Gasu" (ガス) means "gas". It was consumed by Caesar Clown.

Strengths and Weaknesses
This Devil Fruit's main strength is the ability to change into a gas-like form, allows him to float and go inside places that no normal being can, as he was seen hiding inside some flasks when he was informed that the Marines were nearby. However, he can also become dense enough to hold objects, like his cocktail glass. As explained with Brownbeard, he is the one who purified the whole island from poisonous and nerve gases.

There is currently no known weakness to this Devil Fruit, aside from the standard Devil Fruit weaknesses.

Usage
Caesar Clown has mainly used his fruit as a means of hiding, slipping into flasks, and floating in the air. He has enough control over his fruit to move freely and seize solids such as a cocktail glass.

Trivia

 * Since this fruit's power revolves around gas and poisonous substances, it is very similar to the Moku Moku no Mi and Doku Doku no Mi.
 * It is currently unknown exactly what type of gas Caesar can turn into, if he can turn into more than one type, or even if the gas is really poisonous by itself.
