Fisto was born on the planet Glee Anselm. He was known for his trademark smile and his unusually close relationship with fellow Jedi Aayla Secura, a relationship that occasionally pushed at the boundaries of the portions of the Jedi Code that forbade attachments.
His distinctive head tentacles contained highly sensitive olfactory receptors that allowed him to detect pheromonal expressions of emotion and other changes in body chemistry. This was indeed a unique attribute not afforded to any other Jedi, naturally, or through the power of the Force. As such, he had hoped to be assigned to the Council of Reconciliation, but was instead elected to the Jedi High Council.
Kit was an extremely skilled swimmer, and honed his Jedi abilities to take advantage of his amphibious origins, making him a deadly foe underwater as well as on land. For instance, he was capable of manipulating water movement through use of the Force for both offensive and defensive purposes. His lightsaber had two crystals employing a bifurcating cyclical-ignition pulse that allowed the blade to be used underwater.

Fresh off of dispatching the Pirates of Iridium early in 22 BBY, Kit later was chosen as one of the two hundred Jedi that accompanied Mace Windu to Geonosis to rescue Obi-Wan Kenobi, Anakin Skywalker, and Senator Padmé Amidala. He fought against hundreds of battle droids and super battle droids in the arena, and even disabled a droid that was accidentally built with the head of C-3PO, grinning the entire time. Kit survived the arena battle—escaping in the same LAAT/i gunship that Masters Yoda, Mace Windu, and Ki-Adi-Mundi escaped on—and then, along with the other Jedi survivors, led the new Grand Army of the Republic in the battle, the start of the Clone Wars.
In one of Kit's first Clone Wars campaigns, he led the Galactic Republic's forces in defeating the Quarren Separatist league, the Quarren Isolation League, on the watery world of Mon Calamari and later forged a new accord on the world that led to joint Quarren-Mon Calamari representation in the Galactic Senate.
Kit Fisto later went back to Mon Calamari when he found out that there were still enemies there. Also, strange individual jell-like creatures joined together to become one being with great intellegence and telepathy. Kit defeated it by scattering the individual creatures throughout the ocean.
Some months later, he would travel to Devaron with fellow Jedi Tholme, Aayla Secura, Tr'a Saa, and the Dark Woman. Their mission was to locate and destroy a Separatist base launching raids on Republic supply convoys. While Tholme and the Dark Woman were injured and Aayla was battling Aurra Sing, Kit and T'ra attacked and captured the Separatist base.
