Final Fantasy 12 offers many longstanding Final Final traditions and features, one of which is of course the ability to summon creatures into battle to aid you in your fight. These creatures go by different names depending on the game, but in Final Fantasy 12 they are referred to as Espers.

There are 13 Espers in total, 12 of which are based on the zodiac signs. Five of these are obtained during the main storyline, but the other eight are entirely optional.

Espers are encountered as bosses, and once defeated, their licenses can be purchased and attributed to a single character.
