Goron
The Gorons are a peaceful race, generally living in mountain areas, eating rocks. Gorons are known to be skilled at making blades, bombs and shields. Gorons can also become extremely large, towering above all other races.
In Ocarina of Time, the Goron race lives on top of Death Mountain, in Goron City. Among them are their leader, Darunia, Biggoron, maker of Biggoron's Sword, Medigoron, Biggoron's little brother, who has makes Giant Knife, and Link, Darunia's son, named after the Hero of Time, Link. The Goron race holds the Goron's Ruby, and make bombs and Hylian Shields. They feed on the rocks from Dodongo's Cavern.
In Majora's Mask, the Gorons live in the Snowhead area, in the south of Termina. They include the Goron Elder, the Baby Goron, and, until recently, Darmani. Throughout the plot of Majora's Mask, Link learns to become a Goron himself by using the Goron Mask.
In The Wind Waker, the Gorons appear as well, only this time as wandering salesmen, travelling the Great Sea in search of valuable goods and rarities. You'll have to trade with these big guys a lot in order to complete the trading sequence in The Wind Waker.
The Gorons are bound to make an appearance in The Twilight Princess as well, as a scene from the second trailer shows.
