Biggoron
This absolutely huge Goron lives on top of Death Mountain in Ocarina of Time, and is a skilled blade maker. In fact, he made the most powerful weapon in the entire game: the Biggoron Sword. However, Link must go through a huge trading session in order to obtain this deadly blade. Biggoron has a little brother, Medigoron, who is also into the sword making business.
Biggoron makes cameo appearances in The Minish Cap and Majora's Mask.
