User blog comment:El Alamein/Braxas vs. Smaug/@comment-4098900-20120831000516

Smaug'll take this. Smaug is bigger for one. Another thing, when they're both shooting out fire and acid, when those collide, Smaug being twice the size of Braxas will allow him ot put out a larger amount of fire; which'll only push Braxas's acid back at her, and allow his fire to go to her. He's also more intelligent, cunning, and will overall dominate in tactics and not doing anything stupid. Braxas isn't stupid so I doubt he can hypnotise her. Acid will go right throough Smaug's armor. Overall Smaug dominates physically and mentally and that will take the battle for him.
