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. In Minish Cap, Biggoron can nibble on your shield and make it a Mirror Shield.

Trivia
Wearing the Goron Mask while speaking to King Zora reveals that Biggoron and King Zora are best friends, and have known each other since childhood.
