Derrown / Legends Derrown was a Parwan who lived during the Clone Wars and worked as a bounty hunter . Derrown was ruthless and considered to be one of the best bounty hunters in the galaxy . As the Parwan ' s biology produced intense electrical fields , it earned him the title of the Exterminator . His Parwan physiology allowed him to reach various heights and vantage points not easily accessible to those of standard density , although he lacked the speed and control that came with such mass . During the second year of the war , Derrown was brought to Serenno , along with other bounty hunters including Cad Bane , Obi - Wan Kenobi disguised as Rako Hardeen , and Embo . He , along with the other ten bounty hunters , would be put in the Box to see who would earn the honor of partaking in a plot to kidnap Supreme Chancellor Palpatine . Biography . In the first challenge of the Box , Derrown , as well as the other bounty hunters , survived the poisonous gas , Dioxis , thanks to the disguised Obi - Wan ' s quick plan to escape . In the second challenge , a room filled with spinning lasers , Derrown was able to once again escape quickly by using his Parwan abilities float to the hole in the roof , where he made his way out , following Cad Bane and Obi - Wan Kenobi . In the third challenge , Derrown played a vital role to the survival of the other hunters . In this challenge , ray - shielded walls began to close in on the hunters , while a switch to deactivate it lay behind another ray shield . Derrown was able to inject himself with an electrified serum , provided by Moralo Eval — which would have been deadly to all the other hunters — to allow his electrified Parawan body to pass through the ray shield . Derrown did so with ease , and shut off the ray shields , allowing the surviving bounty hunters to pass into the final challenge . After the disguised Obi - Wan Kenobi completed the fourth and final challenge , Derrown and the remaining hunters , including Kenobi , Twazzi , Embo , and Bane formed the group with the task to kidnap Supreme Chancellor Palpatine on Naboo . Immediately upon arriving on Naboo , the hunters infiltrated a hangar ; Derrown killed two mechanics , strangling one with his tentacles and snapping the neck of another . After securing the hangar , all the bounty hunters were given their instructions by Bane . Derrown was assigned to be disguised as a Senate Commando ; he would breach the ray shield that would be surrounding the chancellor and destroy the main generator , allowing the rest of the hunters to make off with the chancellor . On the trail leading to the stage , Derrown was confronted by another Senate Commando . However , he managed to pass through . With nothing to stop him , Derrown sneaked beside the shield generator , deactivated it , and put it on self - destruct . The blast knocked Chancellor Palpatine unconscious and blew his cover . Anakin Skywalker rushed to attack Derrown and the Parwan used his blasters to fire at Skywalker , only to have them sliced in two by the Jedi ' s lightsaber . Derrown was then able to subdue Skywalker with ease by electrically shocking him with his tentacles . Derrown then attempted to escape using his jetpack , but Obi - Wan Kenobi , still in disguise as Rako Hardeen , used a sniper rifle to disable the jetpack , sending Derrown spinning out of control and into the ground . Later , Derrown was seen at Plop Dribble ' s on Stobar . Behind the scenes . The character of Derrown was voiced by Matthew Wood .
