Kit Fisto was a Nautolan Jedi Master during the last years of the Galactic Republic. He was among the Jedi who fought in the Battle of Geonosis and was one of the few survivors out of the 200 Jedi who fought in the battle.
He became a Jedi General of the Clone Army in the Clone Wars and took part in such conflicts as the Mission to Vassek 3 and the Battle of Mon Cala. He was also involved in a mission with his former Padawan Nahdar Vebb to capture the escaped prisoner, Nute Gunray—however, the two ended up facing the notorious Jedi hunter General Grievous inside 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. At some point during the Clone Wars, Fisto was accepted as a member of the Jedi Council.
While he was at the Jedi Temple, Anakin Skywalker revealed to Mace Windu that Chancellor Sheev Palpatine was a Sith Lord. Windu took Fisto, alongside Jedi Masters Agen Kolar and Saesee Tiin to Palpatine’s office to arrest him. In the following duel, after Kolar and Tiin had perished, Fisto was killed by the Chancellor.
