4. The Greek from The Wire (2003-2008, HBO)
Played by: Bill Raymond
Much of The Greek’s life is a mystery. Hell, he’s not even really Greek apparently. But what we do know is that the man is the head of one of the most powerful international crime rings to ever hit television. Like most others, his army specializes in narcotics, but it’s also involved in other unsavory activity, such as human trafficking.
The Greek is a nasty old man who's willing to dispose of anyone or anything in his way of making money. Through-and-through, he is a ruthless capitalist, and there is no activity too illegal for him as long as it brings in cash. He’s also completely untouchable, thanks to his insulation from incrimination, Keyser Söze-like anonymity, and connections at the FBI that warn him when a criminal investigation is close. Despite his age, The Greek is virtually unbeatable.
