User blog comment:- Darkchylde/Dragon Battle 3: Smaug vs. Alduin/@comment-16938192-20140325012913

Alduin is the son of Akitosh, the dragon god of time, he is technicaly imposible for most to kill, he also has a more diverse repitoir of breath attacks so ill agree with the previous comment and say that story and lore wise Alduin would win but Smaug would kill in game Alduin
