VIICC Monster-in-a-box

Zack Fair waiting for a monster-in-a-box in Crisis Core -Final Fantasy VII-.

Monsters-in-a-box (敵入りの宝箱, Teki Iri no Takarabako?, lit. Treasure Chest Containing Enemy) are enemies that appear in treasure chests. After the character opens the Chest, the phrase "Monster-in-a-box!", "Monsters!", or similar is displayed, and a battle begins with an enemy. Usually these enemies are stronger than average foes, and can even match a boss's strength. Monsters-in-a-box were series staples up to Final Fantasy VIII where they do not appear, and only return to the series in Final Fantasy X.

Previous to the use of monster-in-a-box treasure chest starting in Final Fantasy II, the original Final Fantasy surrounded treasure chests with fixed encounters to protect boxes. As a precursor to the monster-in-a-box, enemies fought through this method still had the tendency to be stronger than average. In the later games of the Final Fantasy series, Mimic enemies act as a replacement which appear as boxes and morph into an enemy.

Firion meets a monster-in-a-box.

In Final Fantasy II, Monsters-in-a-box are very common, appearing in almost every dungeon. Unlike later installments, the item is gained before the monster is fought. All types of dragons appear as Monsters-in-a-box in some later dungeons and in the last dungeon, Pandaemonium, several of the game's most powerful armor pieces can be found in boss fights with Monsters-in-a-box.

Cecil finding monsters in a box.

Many monsters-in-boxes can be fought in Final Fantasy IV. After opening a box, a message saying "Monsters!" will appear and the fight will initiate. After winning the battle, the item contained in the chest will be received.

In the DS version, the word "Monsters!" has been replaced by "Enemy Ambush." If there is an item, the item will be received, followed by the term "Enemy Ambush!". For example, in the Giant of Babil, the message box will say:

Found Elixir.
Enemy Ambush!
