This is the Gasu Gasu no Mi. The Gas-Gas Fruit. Caesar Clown ate it, and everything went toxic from there.

• Logia-type Devil Fruit
• Ability: Turns the user into gas and gives full control over all gaseous substances—including poison, explosives, and oxygen itself
• Used by: Caesar Clown, the deranged scientist with a god complex and a lab full of war crimes

This fruit doesn’t just let you vanish into thin air—it lets you weaponize it. Caesar suffocates rooms, detonates clouds, and floats around like a smug chemical ghost. He’s not a fighter. He’s a walking environmental hazard.

The model captures the essence of a fruit that’s all about control, corruption, and chemical chaos.
