The Mimic is an insect/mimic-type enemy in Final Fantasy XII. It can be found in the Barheim Passage. They are usually found as fake treasure chests until the player tries to open them. However, an observant player will notice a subtle differentiation in color that'll give the mimic away. Information from the mimic's creator's journal can be found in the Bestiary entry of the Urutan-Yensa.

Being an insectoid with four sharpened limbs and a hard, metallic shell. Preferring to feast upon brains of high intellect, whereby they may improve their own faculties. By arranging their own carapaces to resemble a coffer, they wait for unwitting prey to 'open' them, thereby proving some modicum of intelligence, and thus suitability for consumption. It is most often humes, wracked with base greed, who fall prey to this simple but efficacious ruse, which in turn has made humes the mainstay of the mimic's diet.
