When Stonebone rejected Bogga ' s initial offer to make recompense , Ktriss was unleashed upon one of Stonebone ' s crewmates , Roko , and devoured him in the company of his peers . Biography . Hutt familiar . Ktriss was a female Hssiss , a species of dragon native to Lake Natth on the Inner Rim planet Ambria , of the Stenness Node . The creatures of that lake were suffused with the dark side of the Force — the result of a powerful Jedi Master trapping the planet ' s darkness there . As such , Ktriss was able to subtly manipulate the Force , using its power to confuse the minds of her prey . While still young , Ktriss was happened upon by a traveling Hutt known as Great Bogga , who was the crime lord of the Stenness star system , where Ambria was situated . Bogga was intrigued by the young Hssiss and her species and captured several dragons to take off - world . All were placed on the black market and sold to colleagues and darksider s alike — all save Ktriss , whom the Hutt claimed as his own . Ktriss was taken to his stronghold on the moon of Vo Dasha , where she acted as the Hutt ' s personal security enforcer . As time progressed , Ktriss grew considerably in size and ferocity , becoming an intimidating presence at the side of Great Bogga . In 3999 BBY , several members of Bogga ' s enforcer gang failed to steal a cache of precious Adegan crystal s from a family of travelers moving through the Stenness Hyperspace Terminal . Ktriss was present when only the gang ' s leader , Gudb , returned in shame , and the sight of him made her drool . Under penalty of Ktriss ' wrath , Gudb was threatened into pursuing the crystals ' owners to Ambria , the dragon ' s homeworld . Leaving Ktriss behind , Bogga accompanied his minions but ultimately returned to Vo Dasha empty - handed and defeated by the Jedi Knights who resided there . Roko ' s demise . Around that same time , Bogga ' s enforcer gang apprehended ore thieves for committing acts of piracy against several of the Hutt ' s allies . Ktriss lay beside her master as pirate captain Finhead Stonebone , the leader of the gang , was brought before them . As atonement for Stonebone ' s crimes , Bogga ordered the pirate to go to Ambria and retrieve the Adegan crystals from the Jedi who had previously beaten the Hutt and his minions . Stonebone , however , refused to involve himself with any act that called for raising arms against Knights of the Republic and remained indignant before the Hutt . Appalled by Stonebone ' s defiance , the Hutt decided to demonstrate for the pirate the consequences of disobeying Great Bogga . Ktriss was called into action and let loose upon Stonebone ' s first crewmate , a humanoid named Roko . Using the dark side of the Force to temporarily cloud the pirate ' s mind , Ktriss rendered Roko immobile as she fell upon him , much to the horror of Stonebone and the rest of his gang . Ktriss consumed all of her victim , leaving only a bloody mess where Roko had once stood . The sight of his comrade ' s death at the mercy of Ktriss was enough to compel Stonebone into service , much to the satisfaction of Great Bogga the Hutt . Personality and traits . Ktriss was a green - scaled quadruped , with black eyes ; a long , massive tail ; and spiked protrusions that lined her back in two rows . She was of considerable stature while on all fours , and when she reared up on hind legs , Ktriss stood taller than an adult humanoid of average height . She also had long , sharp teeth and massive talons . She readily responded to the instructions of her master , Great Bogga , who believed Ktriss to be capable of even devouring his lead enforcer , Gudb , in one bite . Ktriss indeed demonstrated hunger for Gudb , gnashing her teeth and salivating heavily while the diminutive gangster was in her presence . Gudb , however , believed that his own pet gorm - worm , Skritch , was more than capable of dispatching Ktriss . The dragon was loyal to her master and frequently accompanied him . Fear of Ktriss ' abilities was enough for Captain Stonebone to reconsider the offer that Bogga presented to him . Powers and abilities . Ktriss used her large teeth and claws to devour her prey . She was capable of bringing down adult humanoids , evidenced by her overpowering of the space pirate Roko . When Bogga ordered Ktriss to demonstrate her ferocity , the Hssiss obliged by immediately attacking Roko and tearing him to shreds in the presence of his mates . Ktriss was also Force - sensitive and used the power of the dark side when hunting to render her victim temporarily confused , making it easier for her to subdue them . Behind the scenes . Ktriss first appeared in the " " of Tom Veitch ' s " " story arc of the " " comic series . Ktriss is also featured in the " audio rendition " by John Whitman , based on Veitch ' s script . Additional details of her backstory were later established in 2001 ' s " The Dark Side Sourcebook " , a supplement to the " Star Wars Roleplaying Game " , published by Wizards of the Coast .
