Kaa ( Dark Jedi ) Kaa was a Dark Jedi who was very close to her twin sister Lii . They were able to sometimes trick people into thinking that they were simply one individual . They used this trick on General Grievous at an unspecified time before the Battle of Geonosis and were able to gain his trust enough to be invited onto his starship . While there , they were able to steal Grievous ' collection of Sith lightsabers and flee undetected . However , Grievous was not kept unaware for long , and he tracked them to the acidic world of Dica where he engaged them in combat . Kaa and her twin were unable to overcome the powerful cyborg , and they were forced to flee without the stolen weapons . Biography . Origins . A Near - Human of unknown origin , Kaa was nearly identical to her twin sister Lii in every respect except for the distinguishing vertical tattoos that adorned her face . Her sister possessed the same tattoos but in a horizontal manner . Both Kaa and her sister were adept in the Force , and they had obviously trained in its usage . However , whether they had received training from the Jedi Order or elsewhere is unknown . In any case , the two sisters eventually went rogue in the hopes of becoming Sith . To accomplish this goal , Kaa and her twin rationalized that they would need Sith weapons , and they decided to seek out Sith lightsabers . Theft . It was during this mission that the sisters met with General Grievous , who possessed a small collection of lightsabers that had been previously owned by the Sith . Posing as though the two sisters were only one individual , Kaa and her sister were able to gain Grievous ' trust enough to be invited onto his ship . With the cyborg fooled into thinking that there was only one of them , it was easy for the twins to rob Grievous of his most prized possessions , at least four Sith lightsabers . Although Grievous suspected the Dark Jedi of suspicious behavior , it wasn ' t until after they had departed the ship that he became aware of the thievery . Kaa and her sister left for the acidic world of Dica , but Grievous was hot on their tail . Obviously sensing that the cyborg had found them , the twins faced their foe with Lii carefully concealed behind her sister . As Grievous commanded that the Dark Jedi state her name , the twins revealed their dual nature to the surprised General . Although he was taken aback by the revelation of having to face two Dark Jedi , Grievous still resolved to kill them both and charged the Jedi with his lightsaber . Duel . The three combatants began to duel , with Kaa and her sister both wielding two of the stolen Sith lightsabers . Kaa brought her weapon down upon Grievous , but the cyborg blocked the blow with his metal hands and held the blade fast . Just as it seemed that Kaa would have a premature end , her sister was able to quickly maneuver around behind Grievous to attack him there , but Grievous was able to parry the blow . Still outgunned , the sisters decided to try a tandem attack , and calling to each other , the two jumped away from Grievous ' grasp on Kaa ' s command . The jump placed Kaa and her sister in front of Grievous as they both swung their weapons at the cyborg ' s face . Unfortunately for the Dark Jedi , the attack was only able to slightly scar Grievous ' mask and did no permanent damage . Grievous was able to dodge out of the way by using his talon shaped feet to grapple himself under the cliff side that the trio had been dueling on . Kaa suspected the General ' s antics and peered precariously over the cliff edge . However , just at that moment , Grievous decided to attack . With one quick jump back onto the ledge , Grievous surprised Kaa and her sister and swung his blade at the two Dark Jedi , swiping the Sith weapons out of the twins ' hands . Aftermath . Surprisingly disarmed by the cyborg , Kaa and her sister watched as their prized weapons fell slowly into one of the many acid lakes on Dica . With their weapons gone , the twins fled the scene as quickly as they could . As the two Dark Jedi fled into the mist , Grievous called after them , mocking their naïve attitudes . Behind the scenes . Kaa was created by Yasushi Nirasawa for use in the short comic story , " Dark Jedi " that appeared in " " . Originally published in Japan , those stories were considered to be of " fuzzy " continuity by Lucasfilm . Since then , they have been republished in English in the United Kingdom under Infinities label , which established the material in them as non - canon ical . Abel G . Peña referenced this story somewhat in his article , " " when he mentioned that Grievous had obtained one of his lightsaber prizes from a Dark Jedi on Dica or Necropolis . Whether this refers to either of the sisters definitively remains to be seen .
