In the sixth episode of Game of Thrones Season 7, “Beyond the Wall,” the Night King successfully felled one of Daenerys’ dragons, Viserion. Then, he brought it back to (undead) life before our very eyes. In the Season 7 finale, the newly formed undead weapon destroyed the Wall that’s long-protected Westeros by raining down icy fire.
We don’t know for sure that Viserion is definitely an ice dragon, a creature thought up by A Song of Ice and Fire author George R. R. Martin. But we do know that the undead Viserion is about as close as we’ll likely get to one in HBO’s adaptation of his work.
Martin’s characters reference the deadly beasts in both the Ice and Fire book series and in a children’s novel he wrote called The Ice Dragon. We know, from that text, that ice dragons “breathe cold, a chill so terrible that it can freeze a man solid in half a heartbeat.” And we’ve already seen just how dangerous that breath can be.
A weapon with that much power is obviously a game-changer in the war for Westeros. So we can’t help but wonder exactly how Jon Snow, Daenerys Targaryen and the rest of Game of Thrones’ heroes might be able to stop it from raining frozen fire upon the Seven Kingdoms. Here, in no particular order, are our best guesses for how to kill an ice dragon.
1. Other dragons
Daenerys was clearly devastated when Viserion perished right in front of her eyes. She didn’t just lose a weapon, after all — she lost a child. But though she will undoubtedly grieve, she still has a kingdom to win, as well as two more children, Drogon and Rhaegar.
And Viserion’s siblings may be part of the key to taking the newly reborn ice dragon down. The fantastical creatures that inhabit Westeros are varied, and some — like the giants — are pretty big. But what better way to take down a dragon than with, well, another dragon, or better yet, even two?
Of course, that would leave Drogon and Rhaegar with the terrible task of killing their brother (again). And that may not be something Daenerys would ask them to do. Game of Thrones does love to maximize its drama though, and a battle between the three biggest beasts in the Seven Kingdoms would certainly be that.
