Biggoron, like his name suggests, is a Goron who is approximately the size of a mountain. He first appears in Ocarina of Time, where he can be found sitting atop Death Mountain, scratching at his dry eyes.

At the close of a time-centric trading sequence, Link gives the giant special Eye Drops; in return, Biggoron repairs Link's broken Goron's Sword, which is then made unbreakable and renamed Biggoron's Sword. He has a brother half of his size named Medigoron who resides in the second level of the Goron city and will sell Link a (breakable) Goron's Sword for a steep price.
