IG - 100 MagnaGuard / Legends The IG - 100 MagnaGuard , also known as the Self - Motivating Heuristically Programmed Combat Droid , was an advanced type of battle droid that was used during the Clone Wars as bodyguards of General Grievous , as per Count Dooku ' s order , as well as being specialized infantry on the battlefield . After the InterGalactic Banking Clan secured Grievous ' s services as an enforcer , they refused to hire his Kaleesh , and thus the cyborg general demanded a cadre of " more intelligent battle droids " to serve him . The construction of the MagnaGuards was then commissioned for Grievous ' s service , though the Jedi - killing droids were also occasionally employed to escort Count Dooku himself . Appearance and characteristics . Constructed by Holowan Mechanicals , MagnaGuards were roughly two meters tall , with a humanoid body shape , but possessed a far - superior mechanical anatomy . This allowed for superhuman acrobatics , speed , and combat ability . Their internal systems were furnished with advanced combat learning programs , which , compared to most of the droids utilized by the Confederacy of Independent Systems , allowed the MagnaGuards to adapt to a highly diverse variety of tasks . These tasks ranged from melee and ranged combat to starfighter control . The faces of the MagnaGuards featured two red photoreceptor " eyes , " which were complemented by a backup system mounted on the chest . The droid ' s weapon of choice was the lightsaber - resistant electrostaff , and wore cloaks and head wraps similar to the garments of Grievous ' s old " Izvoshra " elite during the general ' s time as a Kaleesh warlord . They were known to sport Mumuu markings on their cloaks matching those on Grievous ' mask . Several models of the IG - 100 existed , superficially denoted by color — black , alabaster , blue , and the rare gray were all spotted throughout the war . Each model had a specific programming , training , and thus specialty . These droids were part of the same Holowan Mechanicals series as the later IG - 88 line . MagnaGuards were also capable of speech and were programmed to taunt their opponents in a low growling Basic . Aside from Human speech , they appeared to occasionally use an audible form of droid language . When in distress , such as when pinned to the ground , they also make yelping sounds . Hardiness . MagnaGuards were fully optimized to battle and kill Jedi . This was due to not only their impeccable melee functionality but also their capability to withstand a massive loss of structural integrity before total system failure , as well as their inability to feel pain . Even after decapitation , or bisection , they could continue to effectively engage a target . The only sure way to destroy a MagnaGuard would be to stab them in the chest . In addition , they were partly plated with strong duranium armor making it very hard for even a Jedi to destroy the droid . Training . General Grievous was given the bodyguards even though he was very impatient with droids due to their many limitations such as limited artificial intelligence . Count Dooku then commissioned Holowan Mechanicals to develop a cutting - edge warrior droid that would meet Grievous ' s standards . Upon activation , Grievous destroyed all the MagnaGuards present , venting his frustration at being treated as a droid . Grievous then personally trained the rest of his bodyguards in the seven classic styles of lightsaber combat so that they could effectively engage and then kill Jedi . Grievous would not allow any repairs to be made to the droids , believing that their numerous scrapes and battle scars made them more intimidating to enemies . Grievous engaged his bodyguards in practice fights as part of training , often damaging them in the process . Background . Clone Wars . The droids were first used in combat during the Battle of Parein II 4 , where one of Grievous ' s MagnaGuards killed the Jedi Sannen by thrusting its electrostaff through his throat . The MagnaGuards soon proved to be formidable , capable of taking on Jedi and clone troopers with ease , and were regarded as being even more daunting than droidekas by some . Despite their many strengths however , they were by no means invulnerable as Boba Fett managed to momentarily incapacitate one with an ion stunner during the Second Battle of Xagobah , though the bounty hunter was ultimately defeated and left for dead by Grievous himself . Along with their combat duties , General Grievous eventually began using MagnaGuards to do his dirty work , such as when they were used to torture Jedi Master Koth on Saleucami . The MagnaGuards also played a role during Anakin Skywalker and Ahsoka Tano ' s mission to Tatooine , they were attacked in the exosphere by several MagnaGuards piloting " Rogue " - class starfighters . After destroying the droids and reaching the surface of the planet , Ahsoka Tano fought and destroyed three more MagnaGuards , while Anakin fought off Count Dooku . During a mission to destroy a CIS listening post near Ruusan , Anakin Skywalker battled several MagnaGuards that were preventing R2 - D2 from being rescued . MagnaGuards were present at Grievous ' s castle on Vassek ' s third moon . Upon Grievous ' s return to his castle , he discovered his force of elite MagnaGuards had mysteriously been deactivated . When Count Dooku alerted him of the infiltration of his castle by Jedi Master Kit Fisto and his former apprentice , Nahdar Vebb , Grievous realized Dooku himself had deactivated his guards to see if Grievous was adept in handling the Jedi by himself , as Grievous had recently suffered a chain of defeats . During this mission , one MagnaGuard was sent to destroy the Nu - class attack shuttle with a rocket launcher , while another squad was sent to destroy Kit Fisto ' s Jedi starfighter . However , Fisto ' s astromech droid managed to personally pilot the ship to safety . Meanwhile , Nahdar Vebb , who was already in the Castle , managed to destroy Grievous ' s entire escort of droids , only to be killed by Grievous himself . The bounty hunter , Cad Bane , while under contract with the CIS , was given several MagnaGuards for use in capturing keeper of the kyber memory crystal , Jedi Master Bolla Ropal . One stood sentry as Cad Bane tortured the Jedi to death , afterward using its staff to crudely check for any vital response from the dead Rodian . The droids were often employed to capture or kill Jedi , such as during the capture of Jedi Master Eeth Koth over Saleucami . The droids aided the General in getting the upper hand on Koth , surrounding the Jedi and slowly wearing him down with electrostaff strikes . Once Koth was captured , the droids tortured the Jedi in a transmission sent to the Jedi Temple on Coruscant . However , they were unaware that the Zabrak was still cognizant , resisting their torture , and sending a coded hand signal to alert the Jedi to his location . Dooku also used MagnaGuards in subduing Skywalker during a skirmish on Naboo . Dooku and the MagnaGuards were able to capture Skywalker in order to do prisoner exchange for General Grievous . Two of these droids fought Skywalker and Kenobi atop STAPs on Utapau . The droids were also used during the Battle of Boz Pity , under Dooku . During the battle , two of them distracted Mace Windu long enough for the Count to make his escape , and one of them almost killed Asajj Ventress with a blaster under Dooku ' s orders . Delta Squad was forced to fight several MagnaGuards on Kashyyyk during their rescue of the Wookiee chieftain Tarfful . The clone commandos managed to destroy the droids with great difficulty . Near the end of the war , MagnaGuards assisted Grievous in the kidnapping of Supreme Chancellor Palpatine during the Battle of Coruscant . Shaak Ti faced off dozens of MagnaGuards with difficulty before they retreated , alerting her to the Chancellor ' s danger . . This led to a rescue mission , in which Anakin Skywalker and Obi - Wan Kenobi fought two of the droids on the bridge of General Grievous ' s command ship , the " Invisible Hand " , before rescuing the Chancellor . Kenobi beheaded his opponent , only to find himself engaging a still - functioning headless droid . Skywalker managed to bisect the second droid as Kenobi finished the first off . Kenobi also faced four MagnaGuards on Utapau shortly before his fight with Grievous . He incapacitated three of them immediately upon using the Force to drop a large block of metal upon them . The fourth was partly pinned under the block , and then decapitated by Kenobi . Post - Clone Wars . Following the massacre of the Separatist Council by Darth Vader , under Darth Sidious ' s orders , all IG - 100 MagnaGuards were deactivated . However , the Geonosian Gizor Dellso would later reactivate and use IG - 100 MagnaGuards as infantry in his personal army . At least a decade later , two MagnaGuards were reactivated by the Galactic Empire for use as N - K Necrosis ' s bodyguards , and re - designated as NK - 3 s . In addition , a delivery was made for a TK - 555 bobble - head , a battlefield diorama , and blueprints for the IG - 100 MagnaGuards . The bureaucrat Narp Pilyev owned two MagnaGuards and used them as security guards , to protect his apartment on Coruscant . Aside from these examples , other persons of note occasionally employed them as guards and henchmen . Many IG - 100s were commissioned at the end of The Clone Wars which was part of the reason that there were enough IG - 100s to create a private army . MagnaGuards in the galaxy . Notable units . Distinguished MagnaGuards include IG - 101 and IG - 102 , both of whom served on the " Invisible Hand " . Other MagnaGuards who were named were IG - 109 and IG - 138 , who were both destroyed in a training session with Grievous . Another pair , IG - 153 and IG - 182 were employed by Grand Moff 4 - 8C . One of the most noteworthy MagnaGuards was IG - 179 , Iron Knight Luxum ' s chief lieutenant . Weapons and equipment . Armaments . Grievous ’ s bodyguards notably wielded high - quality phrik alloy electrostaffs , blunt energy weapons which emitted a visible , pink , electromagnetic pulse on each end . The lightsaber - resistant nature of phrik allowed the MagnaGuards to effectively deflect and attack a Jedi ’ s lightsaber . This , coupled with the specialized combat mechanics of the droids , made them a dangerous enemy , even to those skilled in the Force . Despite their specialization in electrostaffs , the on - board combat systems of the MagnaGuard , coupled with human like hands allowed them to be trained to operate a vast array of available weapons in addition to much more specialized armaments . Depending on the time and necessity , MagnaGuards were known to use blaster rifles , grenades , rocket launchers , remote - controlled drones , and lethally irradiating weapons as well as regular melee weapons . On - board utilities . Along with their weapons , the droids made use of many gadgets , such as built - in tow - cables , a personal cloaking device , and magnetized limbs . At least one MagnaGuard was known to have the ability to extend its arm many times its usual length . Another tool was a violent self destruct sequence , used if the system was still functional after severe damage . This was utilized by MagnaGuards who were encountered by clone commando squad Delta on Kashyyyk . In addition , these particular droids could fire pairs of small seeking missiles from internal magazines in their back plating . Behind the scenes . Grievous ' s MagnaGuards were acted in Revenge of the Sith by stunt performers wearing green and blue jumpsuits , which were then replaced by computer generated models . The MagnaGuard design was originally proposed by concept artist Warren Fu as a design for Grievous himself . George Lucas himself then reviewed it and asked for Grievous ' s final appearance to be developed from it , but it was nonetheless eventually used as the MagnaGuard . In the original script of Episode III , MagnaGuards could talk , but this concept did not make it to the released film . In " Star Wars Galaxies " , as part of the Second Delivery subquest , the player has to obtain blueprints for the IG - 100 MagnaGuards as one of the required items for the sidequest . It along with two other required items ( a TK - 555 bobble - head and a battlefield diorama ) were obtainable only through Email Collection system .
