Subterranean Lava Dragon: Volvagia is the boss of the Fire Temple, the second dungeon in the adult portion of The Legend of Zelda: Ocarina of Time, and the fifth dungeon overall. Volvagia is a monstrous dragon and was a blight upon Hyrule, specifically Death Mountain, for many years prior to the events of the game. He flies through the air in a blaze of fire and dives through pools of molten lava, unharmed despite their intense heat. Volvagia is infamous among the Gorons for devouring their kind alive, but was eventually defeated and slain by the Hero of the Gorons, who wielded the Megaton Hammer.
