George 'Mac' Mchale - An old friend of Indy's, they served together during World War II as spies for the Allies in Europe, acting as double agents in Berlin.Mac's resourcefulness shines through, as he can spin so many stories that its impossible to tell what's the truth. He's claimed to be a CIA agent, a double agent, and a common thief with gambling debts. All that's known for sure is this - he is playing both his old pal Indiana and the Soviets for what maybe the greatest treasure the world has ever known: a city of gold!
