Puppetmasters are a recurring job class in the Final Fantasy series. While only selectable as a job in Final Fantasy XI, they appear as part of the story in the worlds of Final Fantasy IV and Final Fantasy VII. They use nonliving objects to attack in battle.
Luca, the princess of the dwarven kingdom, has possession of several living dolls, collectively called the Calcabrina. They serve as a boss fight, and in Final Fantasy IV: The After Years, appear as playable characters alongside Luca herself.
In addition, the monster Marionetteer could be considered a sort of enemy Puppetmaster of sorts, as they appear with and summon doll-type monsters: Evil Doll and Marionette. Other than their dolls, they have no significant attacks or abilities.
In an early version of the script, Reeve was called an "Inspire", capable of breathing life into inanimate objects. However, this plot point was dropped before the game was released.
Puppetmasters use Automatons to aid them in battle, and they can customize them to fulfill a variety of roles and use a number of techniques. The Puppetmaster is also second only to the Monk in the art of hand-to-hand combat.
While Puppetmaster is not yet a playable class, it was mentioned in a player's poll as an example of a pet job that may be added to the game later. The Mammets found throughout Ul'dah strongly resemble the Automatons in Final Fantasy XI, and as the Pugilist guild is also in Ul'dah it is possible Square-Enix intended to pair Hand-to-Hand fighters with robots at some point anyway.
