9 Game Of Thrones Warriors Who Could Defeat The Night's King

Dany herself isn't a warrior as such, but she does happen to have 3 dragons and an army of Unsullied at her disposal, so that's a hell of an equalizer when it comes to wiping out wights and Walkers. 

It's highly unlikely that Daenerys Targaryen won't play some kind of significant role in the final battle for Westeros. Many fans theorize that she and 2 other main characters will ride the dragons into battle just as Aegon and his sisters did in the War of Conquest. 

And though George R.R. Martin does seem to enjoy playing around with readers' expectations, one would assume that Dany at least will have the opportunity to unleash a fiery reckoning from the back of Drogon. 

This is the "Song of Ice and Fire" after all, and one of those things doesn't fare so well when introduced to the other. Though we haven't seen a Walker taken down by anything aside from dragonglass and Valyrian steel, it's a safe bet the Night's King wouldn't be walking away from a blast of flames courtesy of Dany and Drogon (Drany?)
