B2 super battle droid / Legends The B2 super battle droid ( SBD ) was an upgraded version of the B1 battle droid , with superior armament and armor . They were manufactured after the Invasion of Naboo proved the need for stronger droids . B2s were used by the Trade Federation , the Techno Union , and later , on a much larger scale , the Confederacy of Independent Systems . Some units were later reactivated on Mustafar by Gizor Dellso and other members of the Separatist holdouts , and the Galactic Alliance also used some B2 units during the Yuuzhan Vong War . Characteristics . One of the main design flaws of the standard B1 battle droid was its reliance on a Droid Control Ship to provide a signal ; if the ships were disabled , the battle droids would become useless . To remedy this , the super battle droid did not rely on such a signal and had a greater capacity for independence . However , the droid still operated best with a command signal , otherwise , they tended to forget about enemies as soon as they moved out of visual range . Additionally , the sturdy duranium frame of the super battle droid was larger and more heavily armored than those of a B1 . Unlike its predecessor , the B2 ' s delicate processing unit and signal receptor were buried deep inside the torso , offering much more protection from enemy fire . Small fully - automatic dual laser cannons were mounted on their right forearms , although in some cases this was replaced with a triShot weapon system . The B2 - HA model ' s left forearm was replaced by a rocket launcher . They could use external weaponry ( except in rocket launcher configuration ) , though their large hands had difficulty with smaller blasters . Instead , they were equipped with special blasters that only responded to signal emitters built into the hands . For the sake of efficiency , they used many B1 parts . Their feet were also outfitted with specialized equipment for difficult terrains , such as climbing claws . Their arms also were modular , capable of exchanging their laser cannons for other specialized weaponry . When they were not using their built - in laser cannons , they had their right forearm locked upright . As heavy infantry droids , B2s could take much more punishment than their flimsy predecessors . Even after being defeated , they could detach their torsos and keep up an attack although this was detrimental to their combat skill . Despite such traits , some models seemingly suffered low heat tolerance and were subject to bursting into flame upon contact . Most post - Battle of Geonosis B2 droids were capable of communicating with each other using an oversimplified version of Galactic Basic Standard . History . Clone Wars . The B2 was preceded by the lesser - used prototype beta version . Soon after the Invasion of Naboo , the Trade Federation was researching a new type of battle droid . Commandos from the Royal Naboo Security Forces seized the research facility and discovered the data about this new battle droid . During their first deployment at the Kashyyyk Trade Rebellion in 28 BBY , the new B2 designs proved to be a match for the local Wookiee warriors . Super battle droids saw use throughout the Clone Wars as soldiers for the Confederacy along with its smaller cousins and the dreaded droidekas . Most super battle droids wore an unpainted dull silver tone , likely to differentiate them from the tan coloration the Confederacy used for its standard battle droids , or perhaps due to varying manufacturers . On occasion , they would be painted with green markings for camouflage . Some Super Battle Droids were used as scouts to observe the plains of Geonosis , mostly because of their brute strength and their ability to destroy modest ground targets . This pleased many of the local Geonosians affiliated with the CIS , thus sometimes using the B2s as " spire guards . " The droids eventually were able to express certain emotions , though having catastrophic grammar . They possessed a more violent temperament than the B1 model , to the point they would even strike down allied units in order to quickly intercept enemy targets , as seen in the Battle of Geonosis . As well as that , they were also considerably more durable and intelligent , capable of easily withstanding light blaster bolts . Super battle droids were often retrofitted with adversarial specific parts . However , this method was introduced late in the war and had little effect on the outcome of the conflict . One known model change was the introduction of the grapple droid , which had heavier armor and a larger frame . This droid was programmed to be a close combat model able to receive primary lightsaber slashes and disable enemies through its electrified claws . Another specialized variant was involved in the release of the swamp gas toxin on Ohma - D ' un . The D - 60 assault droid , another variant , was used in the Battle of Cartao by CIS forces . two jetpack - equipped variants of the droid , the jump droid , and the rocket droid , were also developed . Other variants included super battle droids armed with various weapons , such as the Mortar Super Battle Droid , the Anti - Air Super Battle Droid , and the Repeater super battle droid . A more heavily armed and armored version was the Heavy super battle droid , and orray trooper s were B2 droids armed with flamethrowers which rode orrays . These variants were produced at Geonosian troop center s . The B2 battle droid was designed by the Techno Union using the existing B1 design as a template . After prototypes were successfully tested , Count Dooku struck a deal with Poggle the Lesser , Archduke of Geonosis , to mass produce these droids . Further orders were placed on worlds controlled by Baktoid and quadrillions of B2s were soon running off the assembly lines . Despite their advantages and ease of production , however , they were not manufactured as extensively as their inferior cousins , the B1s . During the Clone Wars , B2s would become an important component of the Separatist Droid Army . They participated in most battles in that conflict including the Battle of Geonosis , Battle of Muunilinst , Battle of Coruscant , and Battle of Kashyyyk , and innumerable others throughout the galaxy . B2s were used as shooting range targets as part of the training of clone sharpshooters . A training model was used on Kamino for the training of Clone cadets . Following the execution of the Separatist Council by Darth Sidious ' s new apprentice , Darth Vader , the B2s were deactivated . Post - Clone Wars . A few years after Order 66 , Gizor Dellso reactivated a Droid Foundry on Mustafar . Among the reactivated production lines were a few lines that produced B2 battle droids , providing Dellso with an acceptable amount of B2 ' s in his droid army . After the Clone Wars , a few entrepreneurs found warehouses filled with the droids . Many were sold to gangs or major crime lords for enforcement . Others would be used by the various Separatist holdouts . Like some B1 battle droids , B2s were also used as guards inside the Death Watch bunker on Endor . During the Yuuzhan Vong ' s invasion of the galaxy , many B2 droids used by the Galactic Alliance made up a force known as the Orange Panthacs , which beat back an occupation force of Fire Breather s on Mantessa . Behind the scenes . B2 super battle droids first appeared in the 2002 video game " , " released shortly before . " In , The rocket super battle droid fires regular rockets instead of pink ones . In the " Star Wars : Battlefront " game series , the B2 super battle droids are deployed as standard infantry units , while B1 battle droids are in several specialized variants , as opposed to the B1s being more extensively utilized in the movies . Although the B2 super battle droid ' s Databank entry indicated that the droid could operate without a master control signal , in the " " mission " The RAS " Prosecutor " " , any B2 units remaining aboard the " Prosecutor " are deactivated once the " Lucrehulk " - class Droid Control Ship is destroyed . Also in Republic Commando , the right forearm is replaced by a large laser cannon which doubles as a projectile launcher that fires thermal detonators .
