Imperial Terror Soldier The Imperial Terror Troopers were a division of the Imperial Military devoted to special operations . The brainchild of Darth Vader . , the prototype Terror Troopers ' were trained and equipped on Kamino . Overview . Much of the equipment used by the Terror soldier ' s was highly advanced , from the cloaking devices favored by the troopers to the destructive capabilities of the Terror Walker . The backbone of the Terror soldiers squads were Battle droids . Reinforced by the cloaked troopers , the droids were specialized for anything ranging from covert sabotage to out and out destruction . Everything about them was designed for psychological warfare , from the stylized Kaleesh war masks of the troopers to the overwhelming size and capabilities of the walker . Divisions . Terror Trooper . The most visible face of the Terror soldiers , the Troopers were experimental units designed to enter hostile environments and dispose of targets without leaving a trace . Externally , their combat suits appeared to be heavily modified versions of standard Imperial armor , seemingly incorporating design elements from the Sith stalker armor , notably in the helmet design and the clawed gauntlets and boots . The helmet was designed as a stylized Kaleesh war mask , designed to inspire the image of the dead General Grievous . To allow for increased mobility , the Terror Troopers armor was heavily segmented , or entirely missing in certain places . Functionally , the armor was equipped with a personal cloaking device , allowing the troopers to literally disappear . The armor also appeared to include a breathing apparatus of some sort , as evidenced by the mechanical wheezing noise made by many of the troopers . They were armed with a type of Stun blaster , though some did wield standard Imperial Blaster rifles . However , most Terror Troopers preferred to close the distance and attack with their clawed gauntlets , utilizing hit - and - run tactics that literally terrorized their foes . The Terror troopers were vulnerable to energy discharges , such as Force lightning , as these would short out their cloaking devices and other on - board systems . Terror Droid . The Terror Droids consisted of a bulbous , self - illuminated body with four claw - like legs . They often traveled through ventilation ducts and attacked their targets in swarms , quickly overwhelming . Their favored method of attack was to leap at their foes and latch on to their torsos , fiercely attacking from close range . When damaged some Droids would also fix themselves in one place and convert into proximity mines . When latched onto their victims chest , the Terror Droids could be wrestled off , though only with great difficulty . The most effective attack against them was the Force repulse and Force lightning , though these abilities were limited to Force - users . Terror Biodroid . Also known as Terror Giants , these hulking droids are designed for heavy assault and breaching actions . Terror Biodroids consisted of a large and bulky body with two massive , splayed legs and huge , razor sharp bladed arms . Their heads were designed in imitation of Grievous ' mechanical cranium , topped off with the stylized Kaleesh war mask . Their arms were used for cutting through walls and impaling foes , and were utilized in conjunction with the Biodroid ' s surprising speed in aggressive dashes . Though they could be a challenge even for a Jedi of Starkiller ' s callibre , they were not without weaknesses . Typically , their missed lunges with their bladed arms would pierce the ground and get stuck . Also , their lack of flexibility meant that an opponent need only get on their back to avoid their attacks , while fighting back with impunity . Terror Walker . The most dangerous unit within the Terror Soldiers , the Terror Walker was essentially an enlarged version of the Terror Droid . In addition to the basic arachnid - like construction of its type , the Walker also boasted two massive energy projectors connected to its body and a powerful personal energy shield . Due to its size and destructive capabilities , the droid was able to move about the battlefield with relative impunity , destroying everything in its path . Even the powerful Starkiller was forced to rely heavily on environmental factors to bring it down . Notably , the droid was vulnerable to EMP blasts , which would disrupt its shields . History . The Terror Soldiers were one of several programs Darth Vader was spearheading on Kamino , the primary being the Galen Marek cloning experiments . When one of his subjects escaped , Vader hired Boba Fett to retrieve him , giving him command of numerous Terror Soldier units . As per Vader ' s advice , Fett opted to attack the Rebel Alliance fleet and kidnap Juno Eclipse , a Rebel officer with whom the clone subject was infatuated . With the Terror Soldiers on board TIE boarding craft , Fett coordinated the attack on Eclipse ' s vessel , the " Salvation " . The Terror Troopers and Terror Droids led the charge , and most of the " Salvation " crew died quickly . Fett entered the " Salvation " soon after and rendezvoused with several Terror Troopers , warning them that Starkiller ' s Force lightning was liable to disrupt their onboard systems . When Starkiller and Rahm Kota encountered the Terror Troops , Kota ' s Force sight countered their cloaking devices while Starkiller ' s lightning made short work of them . Starkiller would later encounter the Terror Droids and Biodroids , bringing them down . When finally pitted against the Terror Walker in the " Salvation " main reactor , Starkiller relied on EMP blasts from the reactor core to short out the Walker ' s shields , allowing him to attack it directly . Starkiller eventually used Telekinesis to force the Walker through a rent in the " Salvation " hull and out of the ship , while the ship was in hyperspace . The droid dissolved into non - space . The Terror Soldiers also participated in the defense of Kamino during the ensuing battle there . While they were highly effective against the Rebel forces , their effectiveness against Starkiller was negligible . The entire military division was likely destroyed during and after the battle , when the Timira City cloning facilities were destroyed by the Rebels .
