One Piece Odyssee

Caesar has a very gaseous look due to his Devil Fruit ability. He has very long, spiky, black hair, brown eyes, and two curly horns growing from the back of his head. He is rather tall and wears purple lipstick and dark makeup on his eyes. He has a small flat nose and long thin eyebrows. His arms are very thin in comparison with the rest of his body. Caesar wears a big light blue colored coat with "GAS" printed in pink on each side. Under his coat, he wears a pair of diagonally-striped yellow overalls which are striped cross with orange lines. The overall is cut off right under his knees, exposing his hairy legs. He also wears dark purple gloves with the initials "CC" in white on them. Due to his constant gaseous form, he seems to not use shoes, remaining barefoot, though only when his powers were disabled, his feet solidified with the rest of his body along with a simple pair of shoes

A cruel, arrogant, scheming, sinister, and an overall very evil person, Caesar takes great delight in causing harm and destruction to anything and anybody around him. His psychopathic nature is displayed many times, such as when he set off a chemical weapon on Punk Hazard, killing or crippling most of its inhabitants and destroying its environment, selling or creating weapons of mass destruction
