Hronk was a male Wookiee from the planet Kashyyyk. A member of the same clan as the albino Wookiee Tojjevvuk, who had been killed by a Wookiee named Chewbacca, Hronk was determined to uphold a blood feud declared against Chewbacca by Tojjevvuk's father, Tvrrdko. At one point, Hronk nearly defeated Chewbacca in combat, but their fight was broken up by Imperial forces, a new threat that prompted both combatants to escape from Kashyyyk. Tvrrdko eventually called off the blood feud, but Hronk was still determined to kill Chewbacca. In 0 BBY, Hronk was captured by the Empire on the planet Formos and was due to be transported to the Spice Mines of Kessel.
