Smaug was a fire-drake of the North who is one of minor antagonists in the novel The Hobbit, alongside Azog. He is one of the two main antagonists (the other being the Mayor of Lake-Town) of the second film and a minor antagonist of the last film. He is evil, short-tempered, lazy, impatient, mean, seflish, ruthless, dangerous, greedy, angry, agressive, murderous and mad.
Despite having a similar size to the Sky Whale, the largest and fastest passenger plane in the world, Smaug is actually one of the smallest dragons in Middle-earth, compared to the mountain-sized Ancalagon the Black.
