"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 has a widow's peak, sharply edged facial features, and dark eyeliner surrounding his eyes, with large eyelashes on his lower eyelid, and a bulging vein on the side of his head. His shoulders are abnormally large, extending over his head. He has his ear pierced three times and has four crosses tattooed on his chest.

In the manga he is shown sporting a black jacket, with a white stripe coming down each arm. He also wears black shorts that have a white stripe coming down each leg, a large belt, and kneepads. Ideo also has bandages wrapped around his calves and feet, along with light colored gloves.

His anime appearance is largely the same, with the exception of his gloves and the stripes on his arms and legs. In the manga they are depicted as being white while the anime portrays them as red.
