Goron's new design featured in Twilight Princess

Series: Zelda series
First Game: The Legend of Zelda: Ocarina of Time

Gorons are a species with a hulking appearance, even though they are usually very peaceful. Gorons have appeared in quite a few Zelda games, originating in The Legend of Zelda: Ocarina of Time. They're large humanoid creatures composed mainly of rock, the same type of rock which their buildings are constructed of. They're technology is not as advanced as that of the Hylians, and they're presumably not as bright as either the Hylians or the Zora. However, they are unarguably the most powerful of the races featured in the game.

Despite being a peaceful species, it may take a while until they earn the trust of outsiders. They'll basically befriend members of other species if they happen to gain the trust of the Goron elders, something that Link is capable of doing in every game in the series (that they've appeared in).

Gorons tend to live in rocky mountain areas. An example of this would be their habitat in Ocarina of Time (and the The Legend of Zelda: Twilight Princess), in which they lived on top of Death Mountain in an area they rightfully deemed Goron City. Surprisingly, the species lived in the frosty area of Snowhead in the Legend of Zelda: Majora's Mask for the Nintendo 64.

In The Legend of Zelda: Phantom Hourglass, you were actually able to play as a Goron named Gongoron, a child of the species, in the Goron Temple. His abilities are dramatically different from Link's, and thus you'll need to master both of them in order to complete the temple.
