Volvagia

In Ocarina of Time, Volvagia was an ancient wingless fire-breathing Dragon that lived in the depths of Death Mountain and was essentially the spirit of the Mountain. It was said that a legendary Goron hero destroyed it with the use of the Megaton Hammer at some point in the past. By the events of Ocarina of Time, Ganondorf revived the wicked Dragon to secure the Fire Temple from intrusion. As this beast has a diet of Gorons, the Evil King also fed the rock people to Volvagia to make an example to the other races that might revolt against him. Incited by Darunia's son, Link, the Hero of Time, sets out to destroy Volvagia to stop the Dragon from escaping the temple and turning Hyrule into a burning wasteland, and therefore repeat the feat the Goron Hero had done.
