"Destruction Cannon" Ideo is a XXX rank boxer who joined as a gladiator at the Corrida Colosseum to compete for the Mera Mera no Mi. Ideo has dark-colored hair pulled back into a tight ponytail and a dark beard. He features a widow's peak, sharply defined facial features, and dark eyeliner surrounding his eyes, with large eyelashes on his lower eyelid. A bulging vein can be seen on the side of his head, and his shoulders are unusually large, extending over his head. He has three piercings in his ear and four crosses tattooed on his chest.
In the manga, he is depicted wearing a black jacket with white stripes running down each arm. He also wears black shorts with white stripes down each leg, a large belt, and kneepads. His calves and feet are wrapped in bandages, and he wears light-colored gloves. In the anime, his appearance remains largely the same, except for his gloves and the stripes on his arms and legs, which are shown as red instead of white.
