Smaug was a dragon.
Smaug the dragon was voiced by Benedict Cumberbatch.
Smaug only appeared in the Hobbit, where he was killed and he never appeared again (because he was dead). So smaug was not in the Lord of the Rings trilogy, but he was in the Hobbit.
Smaug the Golden (with some red I believe).
no he is killed by bard
a red glowing dragon that has thousands of gold piles
Bilbo told Smaug a riddle to keep him distracted.
The main conflict in The Hobbit is trying to regain the Lonely Mountain from Smaug the Dragon.
The dragon Smaug stole it.
* Smaug didn't like them thumping their barrels. * Bilbo in being clever about who he was claimed to be 'barrel rider' in reference to his journey down the river in a barrel. Smaug took this to mean he was one of the Lake-men and vowed revenge for Bilbo's intrusion into his lair.
The Hobbit by JRR Tolkien.
The name of the dragon was Smaug. He was a winged fire drake, and he drove Thrain and Thror from the Lonely Mountain. In Appendix A of The Lord of the Rings he is given the title of Smaug the Golden in the story of how he took over the area around the Lonely Mountain.
