Unidentified IG - 86 sentinel droid 1 During the Clone Wars , this IG - 86 sentinel droid was owned by Trandoshan scavenger Gha Nachkt . Biography . Dangerous cargo . An IG - 86 sentinel droid was created by Holowan Mechanicals to serve as assassin droid . During the Clone Wars , the droid was obtained by Trandoshan scavenger Gha Nachkt , who was constantly scouring abandoned space battle zones for any material , from scraps to droids he could salvage and sell . Nachkt stored the droid with another sentinel droid he had found to a cargo hold of his GS - 100 salvage ship , the " Vulture ' s Claw " . As the IG - 86 sentinel droids were known to be higly unpredictable , the pair could have posed a threat to the Trandoshan ' s life . As such , Nachkt kept the assassin droids deactivated , although they were linked to the freighter ' s computer by electronic wires , so they could be manually activated at any time . In 22 BBY , Nachkt was searching debris with his ship inside Golm ' s asteroid belt , where a battle between the Galactic Republic and the Confederacy of Independent Systems had took place , when the " Vulture ' s Claw " was boarded by Jedi Knight Anakin Skywalker , his Padawan Ahsoka Tano and their astromech droid R3 - S6 . The Jedi were looking for R2 - D2 , Skywalker ' s original astromech droid who was lost during the battle . However , as R2 - D2 ' s memory banks contained secret Republic information , Nachkt , who had indeed found the droid , was planning to sell him to the Confederacy . To prevent the Jedi from finding R2 - D2 , the Trandoshan guided them away from the hiding place of the stolen droid , leading them to the cargo hold where his " unique " collector ' s items , the sentinel droids were kept . Activated . While exploring the hold , Skywalker ordered R3 - S6 to access the freighter ’ s computer and find the ship ’ s inventory manifest . However , R3 - S6 , who was secretly a Confederate spy whose mission was to eliminate Skywalker , activated the two sentinel droids instead . Rising quietly , the assassin droid sneaked up on Tano , and grappled her from behind . Yelling in surprise , she alarmed Skywalker , who quickly ignited his lightsaber and sliced the droid ’ s right hand off , after which he Force - pushed the droid against the other sentinel droid , and the pair violently collided with several crates . Tano ordered R3 - S6 to deactivate the droids , but the pair recovered fast and pulled off the wires keeping them attached to the ship ' s controls . Now able to move freely , the assassins armed themselves with E - 5 blaster rifles and opened fire on the Jedi , who deflected the shots with their lightsabers . The pair pressed the attack , jumping up onto shelves of the gargo hold , shooting relentlessly while moving around perpetually . However , Tano managed to deflect one of the shots back at the one - armed droid , who temporarily lost balance and fell down . Landing on their feet , the droid shoved a crate at the young Togruta , causing her to fall backward , and turned to execute Skywalker behind his back . Before the sentinel droid could pull the trigger , Tano stood up and slashed the droid in half , after which Skywalker destroyed the other assassin droid . After the fight , the Jedi left the ship without compensating Nachkt for the destroyed droids , much to the chagrin of the scavenger . Characteristics . Produced by Holowan Mechanicals , the IG - 86 sentinel droid was part of the IG - series of combat droids , belonging to the droid model considered " one of the most dangerous machine " in the galaxy . While Tano doubted the droid ' s effectiveness , Skywalker knew that in battle , the droid was deadly ; Nachkt believed that even a Jedi could not beat the droid pair without lightsaber . Strategic , logical and possessing an intelligent , independent mind , the droid was superior compared to the more common B1 battle droid of the B - series . When faced with risk of being deactivated , the droid responded by severing connection with the controls of the freighter . Cold and very unpredictable , the droid was hostile to every living being aboard the " Vulture ' s Claw " , and attacked Tano immediately upon activation . Even loss of an arm did not stop the relentless sentinel droid from attacking . The assassin was extremely agile , as evidenced when the droid jumped to the shelves and moved between them with great agility ; even when the droid did lost balance , it fell in a controlled manner on their feet . While nearly invulnerable to the laser shots of an E - 5 blaster rifle , the assassin was unprotected against a lightsaber , by which the droid was destroyed .
