YVH 1 The YVH 1 , or Yuuzhan Vong Hunter One combat droid , was a battle droid developed by Tendrando Arms as a means to effectively combat Yuuzhan Vong warriors . Overview . Nearly two meters tall , the YVH 1 droid was built on a reinforced humanoid - type skeleton and protected with layered , self - healing black - gray laminanium armor that resembled the vonduun crab armor used by Yuuzhan Vong warriors . The skull - like head , glowing red photoreceptors , and external circuitry furthered the Vong - like appearance of the droid , which earned them the moniker " Yuuzhandroids " . This was meant to demoralize and anger the Yuuzhan Vong warriors , as explained below , making them more prone to mistakes . Their war cry , however , was programmed to drive the Vong mad . YVH units were specifically instructed to maximize the enemy loss ratio while minimizing friendly casualties , and used the phrase " maximum efficiency " to praise one another on this skill . The droids included advanced search - and - identify programming that could penetrate ooglith masquers to sort civilians from Yuuzhan Vong . This programming proved essential in rooting out Yuuzhan Vong sleeper agents and hidden provocateurs . Once identified , the YVH 1 could engage enemies with its right arm ' s variable - output blaster cannon or the weapon attached to its modular left arm , which was often a heavy laser cannon , sonic rifle , or projectile launcher . The droid could also attack with sheer strength ; its servos being capable of crushing light armor with ease . Specialized versions of the YVH 1 droids were created , including adaptable camouflage droids , aquatic versions , and miniature versions fitted into the shells of MSE - series droids for espionage . In addition , certain versions were capable of making use of baradium pellets that dealt a high degree of damage to Yorik coral . It was an optional quality for laminanium to be introduced into the droid though it enhanced the endurance of the war droids in combat if used . This armor was capable of surviving a coralskipper ' s plasma cannon blast and regenerating the damage in less than a day ; though the laminanium ingot and the droids power pack would need to be replaced afterwards . After a series of successes , newer YVH 1 droids were modified to include a vocoder package — which mimicked Lando Calrissian ' s voice — of war cries , taunts and insults in Yuuzhan Vong . Lando , founder of Tendrando Arms , was particularly proud of the taunts that proclaimed the YVH 1 superior warriors to the Yuuzhan Vong — a powerful insult considering the Yuuzhan Vong ' s intense hatred of machines and automatons . The droids ' Vong - like appearance , appropriate taunts , unique programming , and incredible combat effectiveness made the YVH 1 a walking blasphemy and strong demoralizer to the Yuuzhan Vong . Since the Yuuzhan Vong had a strong hatred of technology , the creation of these droids proved to be an efficient and creative method of demoralization . History . The first YVH 1 , whose prototype , YVH 1 - 1A , was designed by Lando Calrissian and produced by Tendrando Arms was activated in 27 ABY , two years after the Yuuzhan Vong War began . This prototype was involved in a weapon ' s demonstration on Coruscant with Chief of State Borsk Fey ' lya , General Garm Bel Iblis and Wedge Antilles in attendance alongside Leia Solo and Han Solo . After the droid ' s demonstration , it detected the presence of Yuuzhan Vong infiltrators and while its weapon systems were deactivated , it managed to aid in the elimination of the enemy agents before they could assassinate Chief of State Fey ' lya . This helped secure production of the droids and they began to see service in the war against the Yuuzhan Vong invaders . YVH 1 droids served the New Republic and its successor government , the Galactic Federation of Free Alliances , in many battles . Their first mission deployment was the Mission to Myrkr where they assisted the Jedi Myrkr strike team with the infiltration of a worldship that was breeding the Voxyn . In addition to that mission , YVH 1 droids were involved with the Battle of Coruscant , the occupation of Borleias , and the Battle of Yuuzhan ' tar . After the war , the YVHs were used as bodyguards or for heavy assault . Lando gave a customized YVH 1 named Nanna to the Skywalkers as Ben ' s personal defender , and another to the Solos . Tendrando Arms also built a set of customized YVH 1 droids , called YVH 5 - S Bugcruncher s , for use against the Dark Nest . YVH droids were also used by Corellian officials in 40 ABY , such as Thrackan Sal - Solo and Aidel Saxan during Operation Roundabout . Sal - Solo ' s droids attempted to kill Jacen Solo aboard Centerpoint Station , while Saxan ' s droids were used as decoys to kill Jaina Solo , Zekk , the Falleen Jedi Thann Mithric , and the Bothan Jedi Kolir Hu ' lya . While on an investigation of the Ducha AlGray ' s Hapan estate , Jaina Solo and Zekk were attacked by two YVH 1 droids in the possession of the Ducha . However , even two of the deadly droids were not able to defeat the pair of Jedi . The YVH 1 was also the basis for SD - XX , Jacen Solo ' s security droid . Behind the scenes . In spite of the YVH ' s photoreceptors being described as red in novels and beyond , all official images of the droid depict these photoreceptors possessing a yellow color . This discrepancy has , thus far , not been addressed .
