Game Of Thrones Season 6: 10 Characters Who Can’t Die
2. Night's King
The Night's King is a character, the Night's King is the greatest threat in the Known World, the Night's King is 'unkillable' as things stand. For starters we don't even know if he can be killed. Will the Valyrian steel work to the same effect as it did on another White Walker? We're yet to find out. He's got to have some weakness, but we're yet to 100% uncover it so far.
But even if the Night's King could be held to the mercy of a Valyrian steel sword, it's far too soon to be even considering his demise. The White Walkers are another set of slow-burners, and while they've always been the ultimate enemy, nobody in Westeros realised that until now. Their presence will continue to grow, but you can fully expect the Night's King to be leading his forces south of the Wall beyond Season 6. And you know what? He's so sharp I almost want the guy to win...
