What does smaug look like and what does he have in common with other dragons. In chapter 1
The characteristics most dragons have in common:
Dragons steal gold and jewels, you know, from men and elves and dwarves, wherever they can find them; and they guard their plunder as long as they live (which is practically forever, unless they are killed), and never enjoy a brass ring of it. Indeed they hardly know a good bit of work from a bad, though they usually have a good notion of the current market value; and they can't make a thing for themselves, not even mend a little loose scale of their armour. There were lots of dragons in the North in those days, and gold was probably getting scarce up there, with the dwarves flying south or getting killed, and all the general waste and destruction that dragons make going from bad to worse.
Smaug was described as greedier than the others.... stronger and more wicked too.
There was a most specially greedy, strong and wicked worm called Smaug.
Smaug was amazing to behold...
There he lay, a vast red-golden dragon, fast asleep; thrumming came from his jaws and nostrils, and wisps of smoke, but his fires were low in slumber. Beneath him, under all his limbs and his huge coiled tail, and about him on all sides stretching away across the unseen floors, lay countless piles of precious things, gold wrought and unwrought, gems and jewels, and silver red-stained in the ruddy light.
Smaug lay, with wings folded like an immeasurable bat, turned partly on one side, so that the hobbit could see his underparts and his long pale belly crusted with gems and fragments of gold from his long lying on his costly bed.
