Smithy is the main antagonist and final boss of Super Mario RPG: Legend of the Seven Stars and the titular leader of the Smithy Gang, an organization that attempts to rule over Mario's World during the events of the game. In order to do this, Smithy tried to get rid of the power of wishes from the world, and, in its stead, filled the world with weapons. He is a dark-grey mechanical creature that wears a gold crown and has an extremely long white beard; the Nintendo Player's Guide has compared his appearance to that of Santa Claus.[1] He hails from another dimension, a dimension that is accessible by the gateway Exor. In his dimension, he resides in his Factory, where, day and night, Smithy creates anthropomorphic weapons which he uses against other worlds. It is also implied during the final battle that multiple versions of him were made, and that there were possibly plans to mass-produce him, due to the various heads littered in his final battle arena.

Although originally depicted as a calm and collected leader, Smithy is revealed to be highly ill-tempered, as shown by his fit of rage upon being defeated the first time by Mario and his allies, which culminates in Smithy destroying his recently built headquarters. Additionally, in the aforementioned fit of rage, Smithy apparently destroys three of his henchmen who are simply trying to calm him down.

Ultimately, Smithy is determined to achieve world conquest through the Smithy Gang, confident that his weapons can serve as the basis of his power. As such, Smithy attempts to prevent the restoration of wishes, since the Star Road and the dreams of individuals represent a direct threat to Smithy's reign. 

Smithy's name is derived from the word "smith", which is someone who manipulates various metallic materials and metallic alloys, such as a blacksmith. A smith's workshop is sometimes called a smithy as well.
