Lanayru (Skyward Sword)

Lanayru, also known as the Thunder Dragon, is a character from The Legend of Zelda: Skyward Sword. He is one of the Three Dragons who oversee Hyrule. He is a large, dragon-like Deity who watches over Lanayru Gorge, having been tasked by Hylia. When Link first finds him in the present he is dead leaving behind only a skeleton. When he uses a Timeshift Stone to go into the past it is revealed that the dragon is seriously ill, and cannot teach Link the Song of the Hero. He tells Link that the robots were worried about him, so they planted a seedling from the Tree of Life in the Gorge. However, the seed would not grow. After getting the fruit from the Tree of Life, Link returns to Lanayru to heal him, and to learn the Song of the Hero. After recovering, Lanayru offers the Lightning Round mini-game. Even after recovering he can only be interacted with in the past by using the nearby Timeshift Stone, as in the present he is inexplicably gone.
