Droids are often the funniest characters in Star Wars, particularly the murderous ones. Where HK-47 was a cynical and untrustworthy machine, PROXY is a cheerful, straightforward, and helpful holodroid technically capable of taking on the appearance (and fighting skill) of any character in the Star Wars universe. The only problem with him was that he was programmed to try and kill his master – in this case Galen "Starkiller" Marek – on sight. It's Sith tradition that the master is always in danger from his apprentice, so PROXY was built by Vader to really get this point across. He also served as Vader's eyes and ears (and voice) while Marek was gallivanting around the galaxy executing his orders. PROXY's cheerful apologies to Starkiller every time his assassination attempts failed was one of the game's comedic highlights. If you're a fan of the Peter Sellers Pink Panther movies from the 1960's, the Marek and PROXY relationship is probably the closest thing we've ever seen in games to Inspector Clouseau's combative relationship with his manservant Cato.
