Hi Gurl,

Ancalagon the Black was the biggest baddest dragon ever! He was bred by Morgoth but only appeared at the final battle between the forces of Valinor and Morgoth at the end of the Silmarillion. He was nasty enough to repulse the good guys but was killed by Earendil from his sky-ship Vingilot. His fall was said to have destroyed the the fortress of Thangorodrim.
