- "Unlike previous HK units, the HK-55 model was designed to be a loyal bodyguard, not an assassination droid. Created specifically to combat the Eternal Empire during Arcann's invasion of the Core Worlds, HK-55 was given to Lana Beniko, then head of Sith Intelligence, for her own protection. Although programmed with etiquette protocols to fit Imperial culture, HK-55 still has a few personality-matrix quirks, including an obsession with the term "meatbag" passed down from the HK-47 model. Despite his amiable disposition, it would be a mistake to think HK-55 a less proficient killer than his counterparts."
