Game: Star Wars: Knights of the Old Republic
We're taking it way back to Star Wars: Knights of the Old Republic and another popular "47," HK-47 to be exact, everyone's favorite droid assassin. One thing is clear: Thane he's not. HK-47 (that's "hunter-killer," by the way) is borderline sociopathic, taking pride in his work offering to annihilate anyone who got on his master's bad side. In fact, killing things seems to be cathartic or "fun" to him, certainly making him a dangerous one to cross. But he's so darn entertaining to have arond, especially when he's calling humans "meatbags."
