Falleen / Legends The Falleen were the indigenous reptilian sentient species of the planet Falleen . Biology and appearance . The Falleen were an exotic , cold - blooded reptomammalian species known to be long lived , with life spans averaging 250 years . The sleek symmetry of their features , calculating and cold demeanors , their exotic looks , and their ability to alter their skin meant that the Falleen were often considered to be among the most aesthetically pleasing beings in the galaxy . In addition to their strikingly beautiful appearance , the Falleen exuded pheromones which made them all but irresistible to both sexes , as evidenced when Quinlan Vos fell under the influence of a male Falleen ' s pheromones . They had small scales all over their bodies , as well as slightly clawed fingers and toes . In addition , the Falleen displayed prominent facial and spinal ridges , though females tended to have slighter , more subtle growths . The Falleen were semi - aquatic , and were able to hold their breath underwater for a long period of time , leading exobiologists to believe that the Falleen ' s ancestors were completely aquatic . The appearance of breasts and other mammalian characteristics in Falleen females and males have also led exobiologists to believe that Falleen had a mammal ancestor . They were one of the few species resistant to mind tricks , and had green blood . Society and culture . Falleen society was of a nature , with noble houses ruling over the lower classes . The upper echelons of Falleen monarchies were rife with politics and intrigue , but they rarely spilled blood over blatant disputes or open warfare . The skin pigmentation of the Falleen changed naturally to reflect the mood of the individual ; however , the Falleen long ago mastered the ability to change their skin tone at will and used this as something of a covert weapon in their politics , fostering an appearance of calm , for example , when they were really panicking . As a cold - blooded species , the Falleen respected discipline and control , particularly self - control . They tended to shun public displays of emotion , and were very patient . As a result of this attitude , they tended to look down on the more openly passionate , whom they saw as lacking self - control . Indeed , the Falleen as a species had a towering sense of superiority which they felt was only right and proper due to their discipline and rigid self - control . They also tended to view Falleen , and not Coruscant as the civilized and cultural capital of the galaxy . This arrogance made the Falleen something of an isolationist species , and though they were not a rare species , it was rare to find them away from their homeworld . Young Falleen nobles often toured the galaxy for a while to acquire a taste of life away from Falleen . More often than not , though , this merely reinforced the Falleen ' s biased views and sense of superiority , ensuring that the youth of Falleen never felt the desire to leave home . The invasion of the Yuuzhan Vong , and the fall of the planet to the alien invaders , cut short these trips and isolated the Falleen even more . In the aftermath of the war , many Falleen were seen off world especially on Coruscant . C . 29 BBY , the Falleen Miss Mylla , a courtesan and manager of the entertainment house Miss Mylla ' s Saloon in Lamaredd , was rumored to be the concubine of a member of the Falleen Royal family , an heir to the crown fallen into disfavor or a holo actress hiding from a jealous wife . She was known to have arranged the marriage of an escort working for her with a Falleen Prince . History . Though the Falleen joined the Galactic Republic close to four thousand years before the Battle of Yavin , they later sided with the Confederacy of Independent Systems during the Clone Wars . With the conclusion to that conflict , the Falleen played little part in galactic politics , deciding against joining the New Republic after the fall of the Galactic Empire . During the invasion of the Yuuzhan Vong , the planet fell to the alien invaders . A few of the Falleen joined the Rebellion when Darth Vader razed a city and slaughtered some 200 , 000 individuals to contain a failed biological experiment on the Falleen homeworld . Xora , Zuur , and Prince Xizor were three of the Falleen known to have sought revenge on Darth Vader for the deaths of their families and friends , only to be killed by the very same Sith Lord anyway . Behind the scenes . Different artists have depicted Falleen with either four - or five - fingered hands . In " " , Falleen is misspelled ' Fallen ' .
