Kuja

Kuja is the main villain of Final Fantasy IX. 

He is a Genome who was created by man named Garland. Garland gave Kuja a soul and used him to carry out war, which would allow souls from Gaia to be removed from the cycle of life and be replaced by Terran souls. However, it is learned near the end of the game that Kuja was meant only to be a temporary "angel of death" until Zidane grew up and came to terms with his powers. Kuja realises that he is mortal and destroys Terra. Kuja serves as the penultimate boss in the game. After he loses to Zidane he becomes determined to prevent anything from existing without him. Upon his defeat, he casts Ultima on the crystal, causing Necron, the game's final boss, to be summoned.

Kuja is a "weapons supplier" to Queen Brahne early in the game, and he is the one who pushes her towards war with Burmecia and Lindblum. Kuja gives Brahne the Black Mages, which are souless golems that use powerful magic to overcome the other kingdoms. Kuja also has two servants, named Thorn and Zorn, who lead the Black Mages and carry out his orders. They served as Brahne's court jesters early on in the game.
