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, Oracle of Seasons and Majora's Mask. In Minish Cap, Biggoron can nibble on your shield and make it a Mirror Shield.

On Phantom Hourglass, Biggoron was the name of the chief of Goron Island. However, he wasnt similar to the Biggoron from other games, since this one was normal sized. HE is the father of Gongoron and he is also the one that gives you permission to enter Goron Temple.

Quote from The Legend of Zelda: The Minish Cap Biggoron figurine: "This is a legendary Goron with a body bigger than a mountain. It is so big, in fact, that no one has ever seen it all at once."

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.
