9. Mance Rayder (Ciarán Hinds)
All hail the King Beyond the Wall. This former member of the Night's Watch went rogue and declared himself ruler of the wildlings who roam the frozen north. But even wildlings don't stand a chance against the demonic White Walkers and their zombie minions. Now Mance has gathered all the wildlings' competing tribes together for an unknown purpose – a purpose that Jon Snow has either gone undercover to uncover, or has legitimately switched sides to help out with.
