Cloaker Cloakers and masquers were the two branches of the family of biotechnological bodysuits worn by the Yuuzhan Vong . Like all Yuuzhan Vong equipment and devices , these were living organisms : in effect , they functioned as a second skin for the wearer . Overview . The cloaker was a form of quasi - protective clothing , typically worn in situations where something more durable than robeskin was required , but where the heavy protection of vonduun crab armor was not needed . A masquer , on the other hand , was a disguise that enabled a Yuuzhan Vong to conceal their true identity , typically by impersonating a member of another species . In keeping with the importance of ritual and caste in Yuuzhan Vong society , however , some versions of both cloaker and masquer had significant connotations in the spheres of symbolism and status ; indeed , it appears that the original development of the masquer was for use in religious ritual before being adopted as a means of disguise . Ultimately , though , these differences between varieties cloakers and masquers were primarily to do with their external surface , and the basic biology of all varieties was the same . They were usually tight - fitting full - body garments , donned by laying them on the floor and stepping inside them . The cloaker or masquer then began to form itself around the wearer ' s body , beginning at the feet , and securing itself to its host by inserting tiny cilia through the pores of his or her skins — a sensation which was painful . Once donned , the bodysuit could be worn for long periods of time . When the host wished to remove their masquer or cloaker — a process every bit as painful as putting them on — they triggered the creature by stimulating the seam where it sealed , which on hooded versions usually ran upwards from an opening at the lips to the side of the nose . Variations . Cloakers . The most basic variety of cloaker was a sleek black bodysuit , which could be issued even to slaves . It is probable that this was no different than the ooglith , which in other circumstances provided a hood for the wearer ' s head and a transparent mask across the face . While flexible and form - fitting , the ooglith cloaker also functioned as a highly effective protective suit ; paired with a gnullith breather , an ooglith was proofed against the pressure , atmosphere and temperature differences of most dangerous environments , such as deep water , but for use in the vacuum of space , a special vacuum ooglith was used , a rust - red variant worn along with a lungworm to give an air supply for the gnullith . The cloak of Nuun , worn by the elite Hunters of the warrior caste , was a variety of the ooglith cloaker . This was a bodysuit with an external covering of photosensitive cilia , which visually garbed the wearer in a near - flawless image of his surroundings , in effect a personal cloaking device . Another variety of cloaker was the oozhith worn by members of the Shaper caste . Like the cloak of the Nuun , this had cilia on the outside as well as the inside , which sought out and fed on microorganisms in the air , creating a subtle shimmer to the surface as they moved . The full - body oozhith was only worn by Master Shaper s , however , with Shaper Adept s wearing a sleeveless version that ended above the knees . The oozhith had a small pouch for equipment . Masquers . A relative of the cloaker species , the masquer was designed for disguise . The basic ooglith masquer made the wearer appear Human . Before the start of the Yuuzhan Vong War , Nom Anor spent most of his decades - long reconnaissance mission in the New Republic and Imperial Remnant wearing masquers of this sort . The thought of being disguised as an infidel for so long would later prompt a rare emotion , close to pity , in Warmaster Tsavong Lah . Ooglith masquers were subsequently adopted by other scouts like Yomin Carr , and by the time of the attack on Duro in 27 ABY , Nom Anor had developed a variation known as the gablith masquer , which disguised the wearer as a non - Human alien . Gablith masquers are known for both Duros and Givin , and in contrast to the Yuuzhan Vong and almost all their biot s , a Duros gablith masquer could be sensed in the Force ; indeed , it could at least partially mask the Force - void ' absence ' of its Yuuzhan Vong host from the senses of Jedi . The only other creatures used by the Yuuzhan Vong known to have had a similar Force presence are those like Chazrach and voxyn which were derived at least in part from species were not part of their original genetic stock , suggesting that the gablith masquer may have made use of bioengineered Duros tissue . By 29 ABY , a type of masquer had also been created which allowed a Yuuzhan Vong to impersonate a reptilian Ssi - ruu , a process that involved dislocating limb joints and contorting their bodies agonizingly to imitate the theropod physique of the Ssi - ruuk . Other masquers , perhaps the oldest variety , simply hid the wearer ' s true face behind another Yuuzhan Vong visage , often visibly recognizable as a mask . During the period of the Yuuzhan Vong invasion , this remained a fashion among the Praetorite Vong , although it had fallen out of favor with the Shaper - caste domain s decades earlier . Onimi wore a masquer to disguise his shaming in his guise as Kae Kwaad , whereas conversely , Nom Anor wore a masquer bearing the features of a Shamed One in his role as Yu ' shaa . A Yuuzhan Vong creature also existed called an unmasker , designed to detect a masquer and to force it to peel back from its wearer ' s skin . By 44 ABY , Wraith Squadron member Viull Gorsat had bio - engineered what he called " neoglith masquers " from genetic material found in this galaxy . He was able to craft custom masquers disguising himself and other members of the squadron as other humans , including a perfect copy of General Stavin Thaal , and a fictional species created from crustacean genetic samples found on Kuratooine .
