Speculations of what will become of Daenerys’ dragon, Viserion, now that it was reanimated by the Night King are swirling like Bran’s ravens spying on the activities of the White Walkers and its army of the dead. We all have to wait for the Game of Thrones” season 7 finale this Sunday to get our answer.

But “Game of Thrones” fanatics are not lacking ideas as to what Viserion would turn out to be. We are pretty sure that the dragon will be under the control of the Night King and will be his formidable weapon in the icy quest to conquer the whole of Westeros.

What would be the point of resurrecting the beast if it can be made to obey the Night King’s bidding in the first place?

Ice Dragon

The most talked about theory is Viserion will become an ice dragon. These legendary creatures actually are parts of the lore of Westeros and Essos. In the "A Song of Ice and Fire" novels, ice dragons were mentioned a few times.

In "A Storm of Swords," Jon Snow thought of an ice dragon while in the cold tunnel through the wall of Castle Black. In "A Dance with Dragons," Jon Snow again likened the wind gusts at the Wall to the cold breath of an ice dragon and the road beneath the Wall to the legendary creature’s dark, cold belly.

Ice dragons were also discussed in the ASOIF companion volume "The World of Ice and Fire." According to the legends, these creatures were made of living ice and far larger than the dragons that once existed in Valyria.

Ice dragons also have “eyes of pale blue crystal, vast translucent wings, and breath of cold.”

The breath of an ice dragon was also described as so terrible and capable of turning a man into solid ice very quickly.

These creatures were said to have once wandered the areas of the Shivering Sea, a frigid body of water found in the north of Essos, and the White Waste, a vast wilderness of ice and snow located north of the Shivering Sea.

Is Viserion an ice dragon?

It noteworthy to point out one glaring difference in this comparison. Ice dragons were living creatures, which once existed and may have naturally bred. Unlike Viserion, these dragons were not reanimated animals.

In addition, it is uncertain if Viserion would still be capable of breathing fire or now that it is under the magic of the Night King, its breath would turn icy cold.

But as George R.R. Martin already said, the ASOIAF novels and the “Game of Thrones” tv series are taking separate ways now. The writers of "GoT" could certainly take the characteristics of an ice dragon and use it to make the dragon wight, Viserion a deadly cold weapon for the Night King.
