Vargi

Vargi was a male Wookiee from Kashyyyk who was responsible for the capture and enslavement of many members of his species. When the Galactic Empire began to force Wookiees into slave labor and hired Trandoshans to hunt them down, Vargi left Kashyyyk and allied himself with the hunters in an effort to protect his family and to prevent the wholesale slaughter of his people. He directed the Trandoshans' hunts toward elusive Wookiee communities and provided them with other valuable intelligence; when he returned to his homeworld and told his sister, Mallatobuck, what he had done, she reacted with horror and cast him out of her family. Vargi at one point met Mallatobuck's husband, Chewbacca, and the two developed a mutual dislike of each other.

When the Empire's Wookiee slave trade was shut down in 4 ABY, a Nagai known as Knife plotted to revive it and recruited Vargi into his fold. Vargi sought to enslave every member of Chewbacca's family, and Knife had Mallatobuck; her son, Lumpawarrump; and Chewbacca's father, Attichitcuk; kidnapped. Chewbacca soon returned home from his duties with the Alliance of Free Planets to visit his family, and he too was captured by Vargi, Knife, and their team of Wookiee outlaws. When Chewbacca's Human companion, Han Solo, attempted to free his partner, Vargi began to pummel both of them. Chewbacca only fought back when he discovered that his family had been freed, and he overpowered and defeated Vargi. Other Wookiee captives revolted, and the attempted revival of the Wookiee slave trade was averted.
