The Joker's Thugs are a group of organized violent criminals that work exclusively for the Joker. They serve him in many ways such as assassinations, armed robberies, kidnapping, torture and as his enforcers that go up against the Gotham City Police and Batman himself. Many of his men work for him for numerous reasons including fear, greed or simple insanity. They serve as the secondary antagonists in the 2008 Christopher Nolan film, The Dark Knight.
