Kit Fisto was a Nautolan Jedi Master during the last years of the Galactic Republic. Fisto was known as an expert swordsman, having some of the finest dueling skills in the Jedi Order. A celebrated fighter, Fisto served the Republic as a general for the Grand Army of the Republic during the Clone Wars, a galaxy-wide conflict between the Republic and Confederacy of Independent Systems. Fisto fought in various campaigns and over the course of the war was accepted as a member of the Jedi High Council.

Fisto took part in several battles during the early stages of the war, first serving in the opening conflict of the war on Geonosis and shortly thereafter in a covert operation on the planet Hissrich. Following the escape of Separatist leader Nute Gunray from Republic custody, Fisto and his former padawan Nahdar Vebb were tasked with tracking down the fugitive. Their mission went awry, however, as they instead ended up facing the notorious Jedi hunter and Separatist General Grievous in his lair. While Vebb perished at the hands of the General, Fisto very nearly bested him in combat and escaped with his life but without Gunray, ultimately making the mission a failure.

During a schism between the Mon Calamari and Quarren peoples on Mon Cala, Fisto was sent to aid the Mon Calamari against the Separatist-backed Quarren. The battle proved to be difficult, as the Separatists eventually overpowered the Republic forces. With a Separatist victory looming, Fisto and several others escaped into hiding, though he was eventually captured and tortured. The Mon Calamari and Quarren later rekindled their alliance and repelled the Separatists, aided by the freed Fisto. Following the Mon Cala campaign, Fisto took a more active role on the High Council. As the end of the war drew near, Anakin Skywalker revealed to Mace Windu that Chancellor Palpatine was a Sith Lord. Windu took Fisto and fellow Masters Agen Kolar and Saesee Tiin to Palpatine’s office to arrest him. The Dark Lord easily killed Kolar, Tiin and Fisto near instantly with Windu joining them soon after.
