Suggested by Destroyer Smaug is a dragon so this is a fairly interesting match. I’d say that he has the edge over a generic Dragon because Smaug has proven himself to be exceptionally dangerous in combat. You’re just not gonna be able to stop him very easily. This dragon will have to retreat before the awesome power of Smaug! At the end of the day their abilities are pretty much identical but only one can win. Smaug wins.
