Biggoron is a reccuring character in the Legend of Zelda series, that usually supplies you with extra powerful items.
 Ocarina of Time
Biggoron from Ocarina of Time is a giant Goron living on top of Death Mountain who will forge the Biggoron's Sword for Link. The Biggoron's Sword is stronger and larger than Link's other swords, but it must be held with both hands, so Link cannot hold his shield while the sword is in use.
 Oracle of Seasons/Ages
In The Legend of Zelda: Oracle of Seasons and The Legend of Zelda: Oracle of Ages Biggoron sits atop Goron Mountain, and is part of a series of trades. After completing Oracle of Seasons, you obtain a code that can be used in the beginning of Oracle of Ages to get the Biggoron's Sword halfway through the game, and vice versa.
 The Minish Cap
In The Legend of Zelda: The Minish Cap Biggoron sits underneath the Palace above the Clouds and can be awakened only by fusing Kinstones. After you defeat Vaati and complete the game once, Biggoron can nibble on your shield to turn it into a Mirror Shield that can deflect enemy attacks.[[[category:The Legend of Zelda: Ocarina of Time]]
