Serra Keto was a Human female who served the Jedi Order during the waning years of the Galactic Republic . Trained by the skilled lightsaber master , Cin Drallig , Keto became his prize pupil . In time , she became a Jedi Knight herself . Like her Master , she was a skilled lightsaber duelist , and was known as Drallig ' s finest pupil . Keto used Jar ' Kai , the art of dueling with two blades at once . Clone Wars . Keto fought in the Clone Wars as a Jedi General . Some time during the Outer Rim Sieges in 19 BBY , the war ' s third year , a space station carrying Keto , another Jedi , and a unit of clone troopers was attacked by a pink blob - like species able to combine and morph into machinery . Keto was the sole survivor of the assault and sent out a distress signal in the Outer Rim Territories that caught the attention of Jedi Knight Anakin Skywalker . Leaving his ally , Obi - Wan Kenobi , the " Hero With No Fear " traveled to the space station where he encountered Keto . She demanded immediate transport off the facility . Skywalker , however , refused in order to find out what happened to her unit . Because of his curiosity , the two Jedi were forced to fight the pink shape - shifting creatures , who had shaped themselves into two Separatist spider droid s . They were eventually defeated , but the Jedi were forced to break a bulkhead , exposing them to the vacuum of space . In order to prolong the station ' s existence , Skywalker wanted to activate the emergency ray shields . Keto , however , believed that the only way to destroy the blobs was to allow the station to destroy itself , and them along with it . Skywalker refused to give in to the prospect of death , so he and Keto quickly rushed to the hangar and barely escaped with their lives in his Jedi Interceptor . Raid on the Jedi Temple . Shortly after the Battle of Utapau , the Republic ' s Supreme Chancellor Palpatine managed to turn Skywalker to the dark side of the Force , and began the Great Jedi Purge . Skywalker , now known as Darth Vader , was sent to the Jedi Temple on the planet Coruscant to all the Jedi there . Serra Keto and Cin Drallig made a last stand together , fighting off numerous clone troopers until they were separated by All Terrain Recon Transports . Finally , Keto faced off against Vader in the data room by the Tower of First Knowledge . Despite her emotion - laden dual lightsaber attacks , she deemed Vader to be stronger . During the fight , Keto taunted and provoked Vader , hoping that he would make a mistake and give her an advantage . Unfortunately for her , Vader was able to tire and corner the young Jedi , trapping her in the training room at the base of the Tower of First Knowledge . In desperation , she used the Force to throw a huge pillar between her and her attacker to make an escape . However , Vader dodged the attack and followed her up on a balcony . After a short battle against the Sith , the young Jedi managed to pin Vader to a pillar and attempted to behead him . Vader ducked under her strike , causing her to slice through the pillar instead . Before the exhausted Keto could attack Vader again , the Dark Lord used the Force to cause the pillar she had cut to fall onto her , knocking her off the balcony and crushing her in the training room below . Serra Keto was dead , one of the many Jedi to fall at the hands of Vader . Personality and traits . Serra Keto was confident in her abilities , as shown during her duel with Darth Vader . A selfless woman , she was prepared to sacrifice herself if necessary . She was willing to destroy the ship along with herself to defeat the " machine - aliens , " believing it to be the Jedi way . Keto was also bold , taunting her opponents in an attempt to distract them . Powers and abilities . Keto ' s master , Cin Drallig , developed his own unique style of lightsaber combat , relying on enhanced speed and unconventional and unpredictable movements , and his apprentice followed his lead . Her combat style was fast , dynamic and acrobatic . She was a practitioner of Jar ' Kai , using both lightsabers to strike harder and perform more powerful attacks . Keto proved capable of holding her own against Darth Vader and almost beheaded him before the Sith Lord crushed her under a pillar . Keto was also skilled at telekinesis . Behind the scenes .
