The Gorons are a recurring race in the Legend of Zelda series. The Gorons are a humanoid, rock-eating race that dwell in the mountains. Despite their hulking appearance, Gorons are a relatively peaceful species. They are usually considered, perhaps superficially, to be of low intelligence, although there is no particular indication of this in the games; in fact, there is evidence to the contrary, such as their ability to industrialize ahead of all the other races.
Gorons are physically intimidating, as their height and sheer size are almost double that of an average human, at least in some games. They are presumably silicon-based due to a strict diet of rocks and, possibly as a result, they develop rocky growths on their backs as they age. The apparent immunity to drowning would also stem from this, as the silicate minerals and rocks are extremely common and contain oxygen. Due to their enormous density and weight, likely from high muscle-mass, they are unable to swim, but they do not respire like others do; presumably one who reaches the bottom would be able to make it back out. Some Gorons grow much larger than average, but this is very rare.
Gorons can curl up into the fetal position and roll up to very fast speeds. Gorons with Magic can even sprout spikes if rolling fast enough.
Due to the appearance of five different generations of Graceful Gorons over the course of 400 years in The Legend of Zelda: Oracle of Ages, it can be assumed that the average reproductive age of Gorons is around 80 years.
All Gorons that are seen are male and are referred to as such. They call each other "brother" and never once has a Goron referred to another as "she" or "her". Also, many young Gorons are shown as having a father, but no second parent has ever been mentioned.
Gorons appear to have a friendly, brotherly culture. They do not fight each other unless for entertainment, such as sumo and boxing. Their culture is 'explosive' despite their affability. One Goron said that manhood can only be reached by "rolling with a bomb flower" as if to roll through the explosion. Much of their architecture and habits revolve around fiery rocky explosions and are always closely tied with bombs. In Goron culture, people outside of one's bloodline can apparently be considered family, as they have been known to consider Hylian individuals to be their "brother" and consider them Gorons.
