Sable is an enemy exclusive to the 3D version of Final Fantasy IV, fought in the Developer's Office alongside Sho Takeuchi, Shirma, and Dancer. Sable is a black chocobo that specializes in inflicting statuses, as well as having extremely high Evasion. Its physical attack can inflict Confuse on a target while dealing upwards to 2,000 damage, and will sometimes counter any attempts on it with Beak, which inflicts Gradual Petrify. It is recommended to use high-level magic spells against it, as well as summons to deal with him and the rest of the party.
"Sable" is an adjective commonly used to describe the black fur of animals. It is also used in heraldry to denote "black."
