Caesar Clown has mainly used his fruit as a means of stealth, 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.[1]
In battle, Caesar releases poisonous gases that seems to cause instant death to an average victim, or ignitable gases of tremendous explosive power. He can also absorb and remove the oxygen within his vicinity, removing his weakness against fire, as well as force his opponents into unconsciousness or even death via asphyxiation.[13][9] Out of desperation, he absorbed the H2S gas from Shinokuni into his own body to increase his own size and strength.[10]
