User blog comment:Lightning the Skrill/Who Would Win? --- Night Fury vs Snow Wraith/@comment-3230751-20150717174923

It would depend completely on the environment. If we are going with movie-canon, a Night Furie's blast would decimate a Snow Wraith... possibly in one hit. The difficulty is whether or not the two dragons are in a blizzard. Toothless would normally be much faster and much more manuverable. Toothless is also smarter. However, in a blizzard it would be difficult for him to use sonar, and the Snow Wraith can see very easily. The Snow Wraith may be able to see him at night, as has been pointed out, but that doesn't mean that he would be able to avoid a blast or outfly the Night Fury. In truth, I doubt the Snow Wraith could win unless it is in its preferred environment. In the snow, he would have a huge edge, out of it... he's a bigger, slower, white target that toothless could very easily shoot down.
