Suggested by Eric This is definitely a pretty tough round. Both of these avatars have proven themselves in combat many times over. They’ve mastered all of the elements and can use the Avatar state. Korra seems to have gotten off to a faster start but by the end they were both very skilled. I’m inclined to say that Aang wins as his abilities just sound more impressive overall, but this is one of those fights that could easily change if I were to watch the show myself someday. Alternately, it could just cement Aang’s win even more. At the very least, I don’t see either of these two losing to any other Avatar characters. Aang wins.
