Which black dragon wins? The Dragon King from Fairy Tail or Morgoth's greatest winged reptile?
For some people who might not know about the latter, here's some info;
After clashing with the great eagles that came from Valinor for a full day, Ancalagon was felled and his body turned the great volcanic fortress of Thangorodrim to rubble. Three volcanoes that Morgoth himself raised up to be a great fortress for his side. Their exact size is unknown but this is what the wiki says for them;
Wikipedia said:
The position and size of Thangorodrim are unclear. One drawing by Tolkien, if to scale, would have made Thangorodrim 35,000 ft high, and the statement that it lay 150 leagues (450 Númenórean miles) north of Menegroth puts it too far away for some of the action in The Silmarillion to make sense; a distance of 150-200 miles would have been more consistent. It is possible that with the higher figure Tolkien was not referring to 'as the eagle flies', but rather 'as the wolf runs': the plateau of Dorthonion forced a long detour which added the extra 200, 250 miles to the distance.[2]
So all three volcanos that made up Thangorodrim is roughly 35,000 meters tall. The corpse of this thing could crush them beyond recognition.
