7. Muammar Gaddafi
The movie The Dictator was inspired by his outlandish style, and despotic tendencies, so that should give you a clue as to how ridiculous and cutthroat Muammar Gaddafi was. In 1969, he led a putsch that secured him power, and shortly after he blackmailed all oil producers in his country to start handing him more money.
With the money, he underwent plastic surgery to make himself look younger, constructed lavish mansions, and travelled with his own bulletproof tents with him when he travelled, which he would pitch next to the hotel he was meant to stay in.
In addition to his two wives, he was rumored to have had relations with several of his bodyguards, who were supposed to be (ironically) all virgin females.
