Forbidden is an undead/zombie-type enemy in Final Fantasy XII found in the upper reaches of the Great Crystal, and is the most numerous opponent there. They have the Kaiser Shield as a rare steal. Two versions of the enemy exist with the same item spoils but with slightly different stats. There is a 5% chance that the Evil SpiritRare Game spawns instead of a Forbidden.
Those who are born with undying souls, filled with the purest hatred and jealousy, are wryly called the 'forbidden,' for what sane Creator would truly allow such monstrosities to exist? Being zombified as a result of the gradual decay of the flesh around the eternal soul, yet these cursed beings have ever been the subject of much study by those obsessed with the ideal of eternal life. Perhaps this is why they despise Man with such venom.
