Random Insanely Convincing Fan Theories About The Night King On Game Of Thrones (16 items)

(#12) Jon Snow Is Destined To Become The Night King

The books frequently suggest that Jon Snow will become some sort of king. Reddit user theDarkLordOfMordor theorizes that Snow will actually become the Night King.
We know the Night King has close ties to the Starks. Of course, Jon is a Stark through his mother, Ned's sister Lyanna. What if Jon himself removes the dragonglass from the Night King's chest? What would happen? Perhaps Jon would warg into the Night King, and become the big bad himself. It would certainly be a poetically dismal end for a man who has dedicated his life to destroying the White Walkers.
(#3) Is The Night King An Ancient Stark?

People have been speculating that the Night King is a Stark for a long time, and we've got some compelling evidence. For one, in the books, the Stark family nanny Old Nan tells Bran that the Night's King (his title in the books) was a Stark—named Brandon, in fact.
Even the Stark family slogan, "Winter Is Coming," could be a reference to a Stark Night King's alliance with the Others. Redditor ThouCantTouchThis elaborated on this suggestion, noting the strange mental connection between Bran Stark and the Night King, particularly the fact that both have ties to wargs.
(#11) Rhaegar Targaryen Is Alive, And He Is The Night King

What if Jon Snow's biological father, Prince Rhaegar Targaryen, survived the Battle of the Trident and was actually turned into the Night King? For one, as Reddit user Three_eye_raven_s observed, we've never seen Rhaegar taken out on-screen.
Rhaegar still being alive would certainly account for the weird looks the Night King gives Jon Snow. It would also explain how the Night King could walk through fire—Targaryens are fire-proof, after all. It would certainly make the final conflict of the series all the more poignant if it was between father and son, Rhaegar and Jon.
(#8) The Night King And Azor Ahai Are One And The Same

The Game of Thrones universe features tons of prophesies regarding the man or woman who will save the world. This person is called the Azor Ahai, the Last Hero, and Prince (or Princess) That Was Promised. But what if this storied individual is actually the Night King?
Redditor OjWasFramed12 reminds us that we, the viewers, think the Night King is evil, but we can only see one side of the conflict. One prophecy states that Azor Ahai will wake a dragon, as the Night King has already done with Viserion. Remember: the Children of the Forest created the White Walkers to battle humans, who were destroying them. The Prince That Was Promised will defeat evil—and it's entirely possible that the evil is not the night, but humans themselves.
(#2) The Night King Lured Daenerys North To Get A Dragon

There's a reason the White Walkers didn't attack Jon Snow once they surrounded him and his band of merry men at the frozen lake north of the Wall, according to Redditer DamisuNight's King.
He knew that putting Jon and company in danger would summon Daenerys and her dragons to the north, and that was his real aim: getting a dragon for himself. We know this because he came prepared with special, dragon-slaying javelins (which are not typical White Walker tools) and had no problem taking down Viserion. He knew he would need the dragon to take down the Wall before he could lead his army south into Westeros.
(#9) Nobody Can Really Destroy The Night King, Only Replace Him

What will Westeros do if the Night King is immortal? The reincarnation of Azor Ahai might be able to remove the dragonglass from the Night King's chest, but in order to control the Night King's wights, Azor Ahai would have to become the new Night King.
Or, at least, that's what Redditor AnghkoR_ suggested. Thus, the Night Kingslayer would have to stab himself with the dragonglass, sacrificing himself to save everybody from the onslaught of the undead. He would live beyond the Wall in permanent exile, never able to see his loved ones again.
