Tohno , a Human female , was born during the final decades of the Galactic Republic . She was trained in the ways of the Force by the Jedi Order , eventually coming under the tutelage of a Jedi Master . During her time under her Master ' s instruction , Tohno studied architecture and engineering . When the Clone Wars were initiated in 22 BBY , Tohno and her Master served the Galactic Republic in its Grand Army . Sometime during the war , Tohno ' s Jedi Master died , leaving her without a Master . In 20 BBY , the Separatist Droid Army began expanding its ranks with a seemingly endless supply of droids . One of the many installations which had begun providing the Separatists with soldiers and war matériel was the manufacturing facility that had been established on the planet of Zaadja . Approximately eighteen months after the Battle of Geonosis , the Republic developed a number of plans aimed at destroying as many of these factories as possible . One of these plans called for a strike against the Geonosian plant on Zaadja . Obi - Wan Kenobi , Anakin Skywalker , and Tohno were sent along with an army of clone troopers to gain control of the manufacturing world . The Republic ' s order of battle was developed and approved by Masters Mace Windu and Oppo Rancisis ; to act as a diversion , Kenobi and Skywalker were tasked to lead a large scale attack against the Separatist forces on the planet , while the primary mission was given to Tohno . Her task was to infiltrate the Geonosian facility which was acting as both the planet ' s headquarters and the droid factory , and destroy it using military - grade explosives . Tohno was chosen for the mission because of her previous non - Force studies which had centered on architecture and engineering , skills that allowed her to understand and analyze the unique buildings of Zaadja and determine where best to place explosives for the greatest amount of damage . Once the first phase of infiltration was successful , the second phase of her mission called for her to get inside and determine the most vulnerable pathways and tunnels , then set explosives in positions that would bring the entire structure down swiftly . Tohno managed to infiltrate the fortress successfully , but soon discovered that an entire nest of Geonosians was waiting for such an infiltration to take place . Using the Force to conceal her movements , she managed to get past the majority of the nest , but she was seen by a sentry before she could set the explosives . Skywalker , who had sensed that Tohno was in danger , reassured her that he was inbound to her position with a infantry gunship . Tohno , however , ordered Skywalker and the other Republic forces to remain outside of the droid factory — despite the fact that her success in the mission would mean her own death . Although Skywalker continued to press for permission to come to her aid , Tohno convinced him that he needed to let her go in order for the mission to be successful . Skywalker reluctantly obeyed her , and although she was eventually overrun by the Geonosian guards , Tohno was able to set off the explosives which she had brought with her by using her lightsaber . Tohno sacrificed herself to ensure the destruction of the Separatist fortress . Personality and traits . The Human female Tohno wore a set of brown Jedi robes with a red cloak . She owned a lightsaber containing a green crystal . She had green eyes , red hair , and light - colored skin . During the mission to Zaadja , the Human female Tohno demonstrated her wisdom of the Force through her interactions with Anakin Skywalker , who was allowing his emotions to guide his actions . Near the end of the mission , when Tohno was discovered by the enemy , she remained calm and collected throughout the ensuing confrontation and fought the enemy with great skill ; during the fight , she warned Skywalker not to give into his emotions and to stay where he was . She believed that Skywalker ' s duty was to his clone troopers and the future of the Republic , not to her . Powers and abilities . During the mission to Zaadja , Tohno used her expertise at engineering and architecture to successfully infiltrate the Separatists ' base . She also demonstrated her skills with a lightsaber , disabling hordes of enemies inside the Separatist facility on Zaadja . Tohno also possessed the Force talent of telekinetic lightsaber combat . Her infiltration of the droid factory during the mission to Zaadja allowed her the opportunity to utilize that talent when she was confronted by several large groups of Geonosians . During her final stand in the Zaadja factory , Tohno used the Force to hurl her lightsaber at her pack of remaining explosives , causing a chain reaction which destroyed the entire compound . Behind the scenes . Tohno was created by Randy Stradley for the standalone comic " " , the sixty - seventh issue of the " " comic series . She was drawn by Brandon Badeaux . Tohno was mentioned in " The Complete Star Wars Encyclopedia " entry on the planet Zaadja .
