24. Raylan Givens and Boyd Crowder, 'Justified'
Television has seen plenty of memorable hero/villain matchups, but few if any found themselves on the kind of equal footing that Justified's resident lawman and ganglord took for granted. Played by Timothy Olyphant and Walton Goggins, this duo from opposite sides of the law eventually existed in a sort of symbiosis, in which it became impossible to imagine one without the other. They're Harlan County, Kentucky's version of Batman and the Joker.
