Jedi Master and one of the last members of the Jedi High Council.
Fisto was a Jedi master and general during the Clone Wars. Best known for his green skin, "dreads", and relaxed attitude.
Like most Jedi of his time, Fisto was taken at an early age by the Jedi order due to his affinity towards the force and was trained by master Yoda. After becoming a full fledged Jedi master himself Fisto found himself inthralled within the Clone Wars. He accompanied Mace Windu and about two hundred other Jedi onto Geonosis where two other other Jedi, Obi-Wan Kenobi and Anakin Skywalker, were planned to be executed.
On Geonosis the Clone Wars began with the Jedi getting desperate help from a clone army made for the Republic. During the battle Kit caught a curiously built B1 battle droid who had C-3PO's head put on the body, Fisto realized 3PO as a non-threat and disabled the battle droid body.
Fisto then began serving the Republic as a general for the Republic's new clone armies. One of his very first missions Fisto lead an assault on Dac helping out the indigenous Mon Calamari. His actions on Dac not only helped cripple an ally to the Separatists but also lead to an alliance with the Mon Calamari, giving them representation in the galactic senate. This alliance would eventually lead to the Mon Calamari to help the Rebel Alliance in defeating the Empire.
Even General Grievous almost fell to Kisto's Jedi skills. Fisto was sent with a former padawan of his, Vebb, to a moon, Vassek, to capture the fleeing General Grievous. On the moon they discovered Grievous' castle, where he went to recover and rebuild himself after battles or encounters with difficult Jedi. Despite escaping the many traps and getting very close to killing Grievous once and for all, Fisto and Vebb were cut off from one another after Vebb went headlong after Grievous. Grievous was too much for the young Jedi knight and was able to cut him down. With Grievous now in more control Fisto was forced to escape.
Eventually, after years of suggestions, Kit Fisto became a member of the Jedi Council. Fisto continued to fight and lead in the Clone Wars, even defending Coruscant itself during the Separatist assault. When the secret Sith plot to overthrow both the Jedi and Republic was revealed by Anakin, Fisto along with Windu, and two other Jedi were sent to confront the Sith. Palpatine was ready for the Jedi though, and was able to easily dispatch all the Jedi except Windu.
Fisto has a much more relaxed attitude compared to most Jedi and he would meet most things in life with a bright smile. He was also very humble, it took multiple offers before Fisto was convinced to accept a spot on the Jedi Council due to his own disbelief of his skills.
