8. Tony Soprano (The Sopranos)
One of the most important things in all of the Game of Thrones universe is family. Almost every characters motivations are based on family. Whether it's the Starks trying to get back together, Tywin Lannister trying to establish his legacy, or Daenerys trying to return to the Throne once occupied by her ancestors. Family is everything and no man understands the power of family like Tony Soprano. Since everybody in Game of Thrones has shades of both good and evil in them, TV's greatest anti-hero would fit right into the Kingdom and know exactly how to exert dominance. Running all the organized crime in Kings Landing, Tony would have wealth, power, influence and notoriety. He would likely attract enemies, but few would be able to get close enough. He would ensure the Soprano name would be one of the most well known and feared names in all seven kingdoms. And if you think he's afraid of getting his hands dirty then you don't know Tony Soprano. He would go to all sorts of despicable measures to obtain the Iron Throne. Even if he had to kill members of his own family.
