One of the most notorious droid series in the galaxy, the Hunter Killer, or HK, series of assassin droids are shrewd, disdainful of organic life, and extremely deadly in combat. Perhaps the most famous from the series, HK-47, was custom built by Darth Revan to serve as his personal assassin during the Jedi Civil War. The droid continued to be spotted sporadically throughout the following centuries, though its tasks and current master are unknown.
Scientists working for the Sith Empire created their own model based on HK-47’s designs, eventually mass-producing them under the designation HK-51. Though records of their completion exist, the droids were never deployed in any known conflict or mission, and their ultimate fate remains unknown.
