Biggoron

Biggoron is an enormous Goron, hence his name. In many appearances, he is a master craftsman or otherwise integral to getting a high-powered optional item.

The Legend of Zelda: Ocarina of Time
In The Legend of Zelda: Ocarina of Time, Biggoron appears on the top of Death Mountain when Link is an adult. He is the older brother of Medigoron, who is also a craftsman, but not as much of an expert as him. In his dialogue, he is shown to hold his "r"s as he speaks. Early on, if spoken to, he simply tells Link of his skill. Once Link has the Broken Goron's Sword for him to repair, it is found that an eruption caused hot lava rock to get in Biggoron's eyes, irritating them to the point of preventing him from working. He gives Link a Prescription to give to King Zora, who in turn gives him an Eyeball Frog to give to the lakeside scientist. The scientist uses it to make the World's Finest Eyedrops, which Link must rush back to Biggoron before they spoil. Once he uses the eyedrops, he is able to mend the sword, but due to the slow pace he works, he gives Link a Claim Check to identify his order. Several days later, Biggoron's Sword is finished, and is the strongest durable blade in the game. It is also his finest work, according to him. At the end of the game, he is among the many people celebrating Ganondorf's defeat in Lon Lon Ranch.

The Legend of Zelda: Majora's Mask
In The Legend of Zelda: Majora's Mask, Biggoron lives in the Snowhead region near Snowhead Temple, where it is implied by a sign he normally acts as a guard. While trying to figure out the source of Snowhead's endless winter, he is possessed by the evil from the temple and made to blow a chilly wind on all who approach while cloaked by the storm, thus knocking them into the abyss below. Through this, Darmani III, the Goron hero, is killed. Link can see him via use of the Lens of Truth, and stop his blowing by playing the full Goron's Lullaby with the Goron Bongos near him. This causes him to turn visible, fall asleep, and roll off the platform himself. After Snowhead is restored to spring, he can be found sitting on a butte outside the temple, with no memory beyond investigating the temple.

The Legend of Zelda: Oracle of Seasons
In The Legend of Zelda: Oracle of Seasons, Biggoron lives outside Goron Mountain. Due to the seasons being thrown into chaos, Goron Mountain is plunged into an endless winter, much like Snowhead. Since Biggoron is too big to take shelter inside the mountain, he catches a cold. He can be cured by some Lava Soup from Subrosia, after which he gives him a Goron Vase. In a linked game, a Goron in Oracle of Ages tells Link the Biggoron Secret, which if told to Biggoron, will prompt him to make Biggoron's Sword.

The Legend of Zelda: The Minish Cap
In The Legend of Zelda: The Minish Cap, Biggoron lives behind Veil Falls. He stays asleep until a specific optional Kinstone fusion with another Goron. When spoken to after the game has been completed once, he tells Link that steel is considered a delicacy among Gorons and asks him if he can chew on his shield for a while. If Link accepts, he will chew on it for a lengthy period. Eventually, if spoken to, he will take it out, showing that it has turned into the Mirror Shield somehow.

The Legend of Zelda: Phantom Hourglass
In The Legend of Zelda: Phantom Hourglass, Biggoron is now only slightly larger than the average Goron, has a large amount of hair, and has a son named Gongoron. He is the chief of the tribe, and as such is much closer to Darunia in role than his own typical role. Like the other Gorons on Goron Island, he is highly suspicious of outsiders, but will extend membership of the tribe to anyone who can win a quiz game about the tribe with him. When Link first meets him and asks for the Crimsonine, he tells Link to speak with every Goron on the island and return to him. Once he does so, he begins the question game, with a charge of 20 Rupees. He has six questions, with a prize of increasing Rupee amounts for each correct answer. An incorrect answer means Link loses all his rewards, however. He also offers a single "Gorohint" that takes away an incorrect answer.

The first three questions may be asked in any order. One question is how many homes are on the island; the correct answer is six. Another is what a Goron in a particular spot is currently staring at, that being Linebeck's ship. A third question is how many Gorons live on the island; the correct answer is fourteen. From the fourth question onward, Biggoron starts using dramatic timing when answering whether Link is correct or not. A possible fourth is how many of the Gorons are children, to which the answer is six. Another possible fourth is what color the "odd creatures on the cliff" were, that being yellow. A possible fifth is simply how many Rupees he has won in the game at that point, which is 46 (one green, one blue, and two red). Another possible fifth is how many Gorons are currently outside, which is seven. For the fifth question, he earns a big green Rupee. Finally, he may ask what is on a particular spot on the island, which is a treasure chest, or how many rocks are in a particular home, which is three. Once Link answers six questions correctly, Biggoron declares him an official brother to the tribe, dubbing him "Goro-Link" and giving him a Wisdom Gem. He then asks for the "official payment" of 146 Rupees he won. If he refuses, Biggoron insists that he pay it anyway. If he refuses several times in a row, Biggoron will take them anyway, keeping Link in "good standing." Ciela then asks about the pure metal, and Biggoron tells them it is in Goron Temple, sending Gongoron to guide them.

After Link obtains the Crimsonine, Gongoron asks Link to return to Biggoron. Biggoron lets him take the Crimsonine to use however he likes. He also realizes it is time for Link to leave, so he gifts Link back the initial fee with a bonus, now being a big red Rupee worth 200 Rupees.
