The Cur Nakk is an enemy in Final Fantasy V. They are only fought while escaping from Karnak Castle, and are of no threat to the party and can be quickly defeated with physical attacks. When left alone, they will flee from the battle. They are also fought during the battle with Iron Claw while in its Soldier form, and are no different than the ones fought during the escape minus the 25 MP and their resistance to Lightning and Holy-elemental attacks. Interestingly enough, if one were to leave at least one Cur Nakk alive and defeat Iron Claw while it is in Soldier form, the player will never have to fight Iron Claw's true form after defeating the last Cur Nakk.
