Dragons are a recurring race that usually appear as benevolent guardians or powerful enemies. In "Ocarina of Time", after becoming the King of Evil, Ganondorf resurrects the evil Goron-eating dragon Volvagia, who had terrorized the Goron people in the distant past before being defeated by Darunia's ancestor, who wielded the Megaton Hammer. When Ganondorf orders his minions to capture and feed the Gorons to Volvagia as a warning to his enemies, Darunia journeys to the Fire Temple to rescue his people and defeat Volvagia, but he is defeated because he could not locate the Megaton Hammer. However, Link manages to free the Gorons, slay Volvagia, and awaken Darunia as the Sage of Fire. In "The Wind Waker", the Sky Spirit Valoo acts as the protector and patron deity of the Rito tribe, providing them with his scales that allow them to grow wings. When Link arrives on Dragon Roost Island, he discovers that Gohma was tormenting Valoo, and defeats Gohma to obtain Din's Pearl. Valoo and the Rito later repay their debt to Link by rescuing him and Tetra from Ganondorf during their encounter with him in Forsaken Fortress. In "Twilight Princess", Link encounters a species of malevolent draconic warriors called Aeralfos and the Twilit dragon Argorok, who is the boss of the City in the Sky.
