Cloud of Darkness is the final boss of Final Fantasy III and is encountered twice. It is first encountered in an unwinnable storyline battle after Xande has been defeated. At the very end of the game, after the party has traversed the World of Darkness, the Cloud of Darkness is fought again, but if the player has not freed all the Warriors of the Dark in the final dungeon before doing so, the final boss will have an unparalleled high defense stat and the heroes will find themselves fighting a losing battle.
