Jedi hunter / Legends The term Jedi hunter typically referred to a being or droid who was particularly adept at killing Jedi . Overview . No specific background was common among Jedi hunters ; they came from diverse upbringings and species . Numerous Jedi hunters were Force - sensitives themselves . The majority of Force - using Jedi hunters were members of Dark Side cults and groups that were traditional enemies of the Jedi , the most notorious of these being the Sith . Others were former Jedi driven to the Dark Side by unfortunate , traumatic events , and , believing their former mentors responsible , decided to pursue a homicidal grudge against the Order . Examples of such beings included Asajj Ventress , Aurra Sing , or the Sith Lord Darth Vader . Some Jedi hunters were ordinary beings with bodies heavily augmented by cybernetic enhancements that allowed them to compete with the Jedi on the physical level . However , if the being was naturally Force - sensitive , then the lack of flesh could prevent the use of certain Force powers , such as Force lightning . The most notable example of a cybernetic Jedi hunter was the CIS military leader General Grievous . Grievous was equipped with computers slaved to his brain that increased his reflexes and precision to superhuman levels , and a largely mechanical body that provided him with superhuman speed , strength and stamina . Arguably , Darth Vader could also be considered an example of a cyborg Jedi hunter , as his armored body suit provided him with limited resistance to lightsaber blows , and his prosthetic limbs and implants provided him with vastly augmented strength and stamina . Another example was the Gen ' Dai bounty hunter Durge , who originally received cybernetic implants to combat the Mandalorians , but found them to be equally effective against Jedi . There were also whole series of droids created specifically to assassinate and hunt down the Jedi . As droids could not be sensed through the Force due to their inorganic nature , and could have their physical attributes extraordinarily augmented , they could be extremely effective Jedi hunters . Examples of such droids included the IG - 100 MagnaGuards , HK - 50 series assassin droid s , or the Droideka , though the latter were not originally designed with Jedi hunting in mind . In addition to droid , some organic creatures were specifically bred or altered to hunt Jedi , such as the voxyn and terentatek . These creatures often had their aggressive tendencies greatly enhanced by brain modification and conditioning , and their bodies were often genetically modified to allow for overwhelming physical capabilities or specialized combat abilities . Some , such as the terentatek , were genetically engineered to develop heavy armor plates that provided limited protection against lightsabers . However , many hunters were not Force - users , heavily augmented cyborgs , droids , or genetically created / altered creatures , but were instead ordinary people . These hunters often relied on skill and cunning as opposed to sheer power to bring down Jedi . Equipment and tactics . Skilled hunters understood that confronting a Jedi with standard tactics and equipment was often doomed to failure , so many of them employed novel , unorthodox strategies and weaponry . One of the more standard Jedi killing weapons was the slugthrower , a weapon that employed chemically propelled solid projectiles instead of an energy discharge . These weapons were extremely useful when confronting an individual with a lightsaber , as the standard metal projectiles utilized in most slugthrowers could not be redirected by a lightsaber in the same manner as a blaster bolt ; they simply vaporized on contact with the blade . Flamethrowers also worked well , as the jet of fire produced by one could not be blocked by a lightsaber . A skilled enough Jedi could use the Force to shield themselves from the flames , but this took considerable effort and uncommon strength in the Force . Sonic weapons could interfere with a Jedi ' s concentration , and as such could undermine their connection to the Force . Use of proper mental techniques to cloud one ' s intentions made ambush an option . Quality poisoned darts were silent and worked too quickly for Jedi to counter . These weapons were of limited use on a large - scale battlefield , but deadly against Jedi . The notorious Jedi hunter HK - 47 believed that the best weapons for killing Jedi were either sonic based weapons or high explosives , while poison gas was effective but to a lesser degree . As only a very skilled Jedi was capable of using a lightsaber as a ranged weapon , most Jedi preferred to engage a target at close quarters , making land - mines an extremely effective weapon . Energy shields were also useful , as lightsabers had a difficult time penetrating most military issue energy shields . Many Jedi hunters often used weapons and armor made of lightsaber - resistant materials . For instance , the IG - 100 MagnaGuard series droids utilized electostaffs made of phrik alloys that allowed the droids to engage in melee combat against Jedi , and the bounty hunter Cad Bane owned a specialized , handmade carbine that fired cortosis projectiles . Though this weapon could short - out lightsaber blades and was extraordinarily deadly , Bane rarely used it as the cortosis ammunition was expensive , and firing such ammunition put a great deal of stress on the weapon . During his tenure as a Sith Lord , Revan also developed techniques that enabled Force - insensitive individuals to deal with Jedi Force abilities . Targeting the allies of a Jedi , or even just random bystanders , was a favorite among such Jedi hunters as most Jedi were willing to put themselves in harms way to protect others . Sniping and using cover were also useful , as many Force abilities decrease substantially in effectiveness without a direct line of sight to the target . HK - 47 also believed that it was critical not to over - plan the assassination of a Jedi , as it seemed that such planning often backfired due to Jedi precognition . In addition , it was possible for a Force - insensitive individual to learn how to " hide their minds " from Jedi by broadcasting strong emotions while thinking about something unrelated . This made Force - insensitive assassins in particular very difficult for Jedi to detect with the Force . Psychological warfare was also extremely effective against Jedi , as a Jedi ' s connection to the Force was largely based on their emotional state . Lightsaber collecting was also a fairly common practice among Jedi Hunters . As they were unique to each Jedi , they provided proof of kill , and could be kept as trophies . The bounty hunter Boba Fett and the Mandalorian raider Sherruk were known to collect lightsabers . Some hunters would also make personal use of their collected lightsabers , such as Grievous or Aurra Sing . History . At the end of the Hundred - Year Darkness , Jedi hunters helped defeat the Dark Jedi at the Battle of Corbos . When Revan became a Sith Lord following the Mandalorian Wars , he employed both specialized Sith assassins and Force - insensitive assassins to kill Jedi . Utilizing assassination techniques the Jedi had never seen before , Revan decimated the Order nearly to the point of extinction . During the First Jedi Purge , the Sith Lord Darth Sion achieved infamy as one of the greatest Jedi hunters of all time , along with his Sith triumvirate partner , Darth Nihilus . Nihilus however , did not hunt Jedi in a traditional manner or for traditional reasons . Rather , he sought to kill Jedi as a form of sustenance , using his unique variant of Force drain to consume their life and Force energy . While he could and did strip other lifeforms of their energy , sometimes even on a planetary scale , Jedi were especially targeted by him as they provided more energy than most other beings . Sion , on the other hand , sought the extinction of the Jedi purely out of malice . In the Mandalorian Wars , Dungeon ship s were developed to move and capture Jedi prisoners , and were later reused with Universal Energy Cage s in the Great Jedi Purge . The assassin droid HK - 47 also became a notorious Jedi hunter during this time period . General Grievous was among the greatest and most feared Jedi hunters , personally killing numerous Jedi in lightsaber combat during the course of the Clone Wars . He was notable as a rare example of a non - Force sensitive being who nevertheless could hold his own against the Jedi in lightsaber combat . Following the end of Clone Wars , the clone troopers of the 501st Legion were placed in the service of Darth Vader , a Jedi turned Sith , and the most infamous Jedi Hunter in galactic history . During , Vader , alongside the 501st , sacked the Jedi temple and massacred hundreds of Jedi , from venerated Masters to Youngling . Vader would later go on to kill dozens more Jedi during the Purge until Palpatine called it off , believing the remaining few Jedi to be of no threat to his plans . Due to their role in the Great Jedi Purge , the 501st became vicious Jedi hunters in their own right , earning the nickname ' Vader ' s Fist ' . Following the fall of the Galactic Empire , the Jedi enjoyed a short time of peace , until the Yuuzhan Vong invaded . These extragalactic warriors swept through the galaxy taking entire worlds and waging war on the New Republic . Realizing that their biggest threat came from the Jedi themselves , and hating the fact that they controlled a mystical energy field called the Force , which the Yuuzhan Vong could not touch , and seemed to not even exist in , the invaders called for the extermination of the Jedi in exchange for an empty promise of peace . An entire faction of New Republic citizens caved , forming a group called the Peace Brigade , and began to hunt the Jedi , turning them over to the Yuuzhan Vong . By the end of the Sith – Imperial War , many Jedi were surviving but scattered throughout the galaxy . The One Sith organization placed bounties on Jedi and for the next seven years , new Jedi hunters began snuffing out Jedi who weren ' t careful enough , nearly fulfilling the Sith ' s goal of the Jedi ' s extermination . Soon , all hunters had to keep their eyes out for the last Skywalker , whom the galaxy thought had ended at Ossus . The Sith Lord Darth Krayt wanted him because of his healing power .
