Goron

The Gorons are a peaceful race, generally living in mountain areas, eating rocks. Gorons are known to be skilled at making blades and shields, and also harvesting bombs. Gorons can also become extremely large, towering above all other races.Often, Gorons are slow to trust outsiders unless they can somehow win the trust of a Goron elder.

Ocarina of Time
In Ocarina of Time, the Goron race lives atop Death Mountain, in Goron City. Goron City is a huge rock dome with many rooms. Among the gorons are their leader, Darunia, Biggoron, maker of Biggoron's Sword, Medigoron, Biggoron's little brother, who makes Giant's Knives, and Link the Goron, Darunia's son, named after the Hero of Time. The Goron race holds the Goron's Ruby, and harvested bombs. They feed on the rocks from Dodongo's Cavern.

Majora's Mask
In Majora's Mask, the Gorons live in the Snowhead area, in the north 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.

Oracle of Seasons & Oracle of Ages
Gorons appear in both the lands of Holodrum and Labrynna. In Holodrum, they are located in the Goron Mountains. A giant Goron named Biggoron is located at the summit. In Labrynna, they appear in the Rolling Ridge in both past and present. The Gorons of Labrynna enjoy dancing.

The Wind Waker
In The Wind Waker, the Gorons appear as well, this time as wandering salesmen travelling the Great Sea in search of valuable goods and rarities. You'll have to trade with them a lot in order to complete the trading sequence in the game. Using the Deku Leaf to blow a gust of air at them reveals their faces, confirming that they are indeed Gorons.

The Minish Cap
In The Minish Cap the Gorons appear when you complete Kinstone Fusions with Mysterious Walls. After you summon six of them, you can receive a Bottle and fuse a seventh Kinstone to wake up Biggoron who (after you defeat Vaati) can make you a Mirror Shield. Naturally, they feed on rocks.

Quote from The Legend of Zelda: The Minish Cap Goron figurine: "These rock- and iron-eaters once lived on Mount Crenel in Western Hyrule. Now their numbers are few, and they live quietly in a cave."

Twilight Princess
In Twilight Princess Gorons primarily populate Death Mountain, or more correctly in Spectacle Rock. However, numerous Gorons have migrated to Castle Town as merchants, and a few have moved to Zora's Domain. Notable Gorons are the Patriarch Darbus and the four elders: Gor Amoto, Gor Coron, Gor Ebizo, and Gor Liggs.

In Twilight Princess, the Gorons have constructed a large mining complex within Death Mountain and they have also become more mechanical and industrialized developing magnetic cranes and elevator systems.

They also guard a Fused Shadow piece and the Hero's Bow. The Gorons are governed by four tribal Elders and their Patriarch, Darbus. In the game, Link is at first is not at all welcomed by the Gorons, who attack him on sight. Darbus had become possessed by the dark magic of the Fused Shadow which transformed him into an uncontrollable monster, the Twilit Igniter Fyrus. The four Goron Elders managed to subdue him and lock him away deep within the mines for the safety of the tribe and cut off relations with Kakariko Village. Link is forced to beat the elder, Gor Coron, in a sumo-wrestling contest (using the Iron Boots to even the playing field) to earn their respect and gain entry to the Goron mines. In the mines, he is forced to fight the armored Goron, Dangoro, that protects the Hero's Bow and eventually the transformed Darbus. After freeing Darbus from the influence of the Fused Shadow, the Gorons restore relations with Kakariko Village, many of them (including two of the Goron elders) venture down to Kakariko to help (one young Goron sets up a small shop that opens at night; while the two Goron elders help Malo Mart collect donations to rebuild the east bridge of Castle Town and buy the overpriced shop in Castle Town). The Gorons also help Link by restoring the southern pathway that leads into Castle Town and by selling him arrows, lantern oil, potions, hot spring water, etc. Link can also save a Goron who accidentally got himself encased inside the hardened chunk of molten rock that he uses to unfreeze Zora's Domain.

The Gorons love bathing in hot springs and enjoy sumo wrestling (though its popularity seems to have waned among the younger Gorons). The mayor of Ordon, Bo, is one of a few people known to have beaten a Goron at sumo (the other would be Link) in his youth, thus gaining the respect of the Gorons. However, he used the Iron Boots to level the playing field (as Gorons are heavier and stronger than humans). Link later borrowed the Iron Boots from Bo, and gained respect from the Gorons the same manner.

Twilight Princess is the first Zelda game where Link must fight Gorons. It is the first game to feature a Goron boss (two, to be precise). Link also fights regular Gorons at first, but they are more obstacles than true enemies, as they can not be defeated, only stunned.

Gorons have also apparently picked up the ability to stay underwater for extended periods of time and not need to breathe, as demonstrated by both a child Goron in the hot springs and the adult Goron Link frees from the rock in Zora Domain. It should also be noted that the Gorons have, what appears to be, their own language script which can be seen on the doors in the Goron Mines.

Phantom Hourglass
One tribe of Gorons are found on Goron Isle. Here you beat the Goron Temple and get the Crimsonine Steel, the first Pure metal. Gongoron, a Goron you meet on Goron Isle, lets you control him to beat the boss and the dungeon. After you beat the dungeon he heads to Dee Ess Island, another island with Gorons, where you can play the Goron game.

Trivia
The beta version of Twilight Princess included a boss called Goron Golem, which was formed from many many Gorons.
