HK-47 is an assassin droid and party member in the Star Wars: Knights of the Old Republic video game and its sequel, KotOR II: The Sith Lords. Anyone who's ever played these games and met HK know that he is a bloodthirsty droid and makes no secret about it. He calls organics 'meatbags', he constantly asks if he can kill things, and is just generally vicious. However, he is one of the funnier characters in the game. He proves that the comic relief character can be a badass at the same time.
