Caesar has eaten the Gasu Gasu no Mi,[5] a Logia-class Devil Fruit[6] that grants him the ability to change into a vaporous form, allowing him to float and go inside places that no normal solid being can. He was seen demonstrating this ability when hiding inside some beakers when he was informed that the Marines were nearby.[29] Even in his intangible gaseous form, he can become dense enough to hold objects, like his cocktail glass. It is unknown if this is because he can control the density of his gaseous form. He seems to prefer keeping his Devil Fruit ability active, as he is always either completely or partly gaseous. Caesar can absorb other gases, and he merged completely with the Shinokuni gas to greatly enhance his size and powers.[12]
