HK-47 was a Hunter-Killer assassin droid built by Darth Revan near the close of the Mandalorian Wars. Revan gave up the droid shortly before his capture by the Jedi and return to the Light Side of the Force. HK-47 moved around a lot after that, shifting from owner to owner and killing more than a few of them himself. He was eventually discovered and purchased in Anchorhead on Tatooine by the man who had once been Darth Revan. Reunited with his former master, the droid aided in the infiltration of the Star Force superweapon where Revan killed his former pupil, Darth Malak. HK-47 is unique among droids for his sarcastic personality and his penchant for referring to all biological organisms as "meatbags."
