Katooni's lightsaber was the distinctive lightsaber wielded by Katooni, a youngling of the Jedi Order from the Tholothian species. Constructed from a variety of components, the weapon projected a blue energy blade. Its creation took place on the planet of Florrum in the year 20 BBY.
This weapon saw action during the rescue operation to save Ahsoka Tano, a Padawan, on Florrum, as well as the subsequent invasion of Florrum. Later, it was present during the duel at the Jedi Temple involving Anakin Skywalker, a Jedi Knight, and the renegade Jedi Barriss Offee.
Roughly twenty years prior to the Battle of Yavin, Katooni, the Tholothian Jedi youngling, journeyed with a group of fellow younglings to the planet Ilum. Their purpose was to participate in the Gathering, a Jedi rite of passage where each youngling would acquire a kyber crystal to power his or her personal lightsaber. Katooni's transport to Ilum was aboard the Crucible, accompanied by her peers and their guide, Ahsoka Tano, a Padawan. Upon landing, Katooni and the other younglings proceeded to the Crystal Cave, where they encountered Grand Master Yoda for the commencement of their trial.
Yoda elucidated that the younglings were required to venture deep within the cave's depths to find their destined crystal, warning that failure to return before the exit sealed shut would likely result in their demise. The younglings promptly entered the cave and dispersed to locate their respective crystals. Katooni managed to locate her crystal relatively quickly, but it was located in a difficult to reach location. Ultimately, Katooni successfully secured her crystal, narrowly escaping the Crystal Cave with little time remaining, after having been briefly trapped in ice. Once Petro, the last youngling inside, also emerged, the group returned to the Crucible with Ahsoka to commence the construction of their lightsabers.
Following their departure from Ilum's atmosphere, Katooni and her companions were greeted by Huyang, a droid who had spent millennia guiding Jedi in the construction of their lightsabers. However, before she could complete the process, the Crucible was ambushed by the Ohnaka Gang, a notorious band of pirates led by the infamous Hondo Ohnaka.
After a series of encounters with the pirates, the younglings and Ahsoka managed to repel them from their ship, but Ahsoka was subsequently captured by the gang and taken to their fortress on Florrum. In the aftermath of the attack, the younglings contacted Master Kenobi and relayed the events that had transpired. He instructed the younglings to remain in place until he could provide assistance to them and Ahsoka. While awaiting Master Kenobi's arrival, Katooni attempted to complete the construction of her lightsaber, but it failed to activate.
After their capture by pirates, the younglings and Ahsoka persuade Hondo's men to escort them to Hondo's holding cell. Following some debate, Hondo requests that the younglings display their lightsabers to prove their readiness for the battle ahead. All the younglings activate their sabers, with the exception of Katooni, who was still unable to get hers to function. However, with encouragement from Huyang and Hondo, Katooni finally succeeds in correctly assembling her weapon and freeing Hondo from his electronic restraints.
During the last year of the Clone Wars, Katooni participated in a lightsaber training session led by Jedi Master Tera Sinube within the Jedi Temple on Coruscant. As she and her fellow younglings practiced with their lightsabers, Petro noticed a lightsaber duel unfolding between Anakin Skywalker, a Jedi Knight, and the rogue Jedi Barriss Offee. Katooni and the others observed as Skywalker triumphed over and apprehended Offee, bringing her to justice.
