Fyer is a character from Legend of Zelda: Twilight Princess. He lives at the bottom of Lake Hylia on his island. He offers strange cannon rides for a small fee. This is useful when Link is stuck in human form with no way to get to higher ground. The force of the cannon can launch Link up to the bridge on the lake. Fyer eventually, with the negotiation of Auru, an old friend, lets Link use the oasis flight, allowing him to access the Gerudo Dessert and Arbiters Grounds.
Fyer also reappears with the Sky Cannon unlocking access to The City in the Sky for a steep price of 300 rupees.
Fyer has a picture of a Bullet Bill on his right sleeve.
