Cicero has the appearance of a clown. He wears white makeup that covers his entire face, red eyeliner and dark blue lipstick. He keeps his hair straight and long, with a big clown hat, half black, half white, with a green snake adorned in it and two pompons on each side.
He wears a clown costume, with several pompons as buttons, and a black overcoat.
A technique some may refer to as grotesque, "Ouroboros: The Cycle of Transmigration" is the origin of his namesake. As an Emitter, Cicero is capable of separating his aura from his body to create unique abilities.
When Cicero is found in a dire situation in battle, he can open his mouth and completely extract his Nen from his body, materializing a new body (note it is not a clone, but an exact replica of him) that bursts forth from his original body, that is now an empty carcass. This new body serves as a last resort method that can be used indefinitely (although in a single battle, he can only perform it about twice), as it regenerates any injuries, except for decapitation or bisections.
