The spot-billed duck that smokes cigars, wears a dark Roman legionary's helmet, and always seems angry. He was Zoro's duck on the way back to the Going Merry. His name is another way of saying "Centaur" (which is also what he is called in the Viz Manga). The Centaur (Κένταυρος in greek) was a mythological creature which was part human and part horse.
