Fyrus

Twilit Igniter: Fyrus is the boss of the Goron Mines in.

History
After a disturbance of volcanic activity in Death Mountain, Darbus, the patriarch of the Gorons, went into the Goron Mines to investigate the cause as well as to check on the status of the mines' Fused Shadow. Fyrus is the form that Darbus assumed after being transformed by the power of the Fused Shadow. Due to his ferocity and inability to control himself from the mutation, as well as causing destruction in the mines, the Goron Elders locked him away deep inside the Goron Mines to prevent him from causing further damage.

Strategy
When Link enters Fyrus's chamber, the young hero finds that he is chained to pillars within the room. When Fyrus detects Link, the gem on his forehead lights up and he ignites, ripping the chains from the pillars that bind him. Fyrus must first be stunned by shooting the glowing jewel on his head with an Arrow using the Hero's Bow. Link must then equip the Iron Boots and grab the end of one of the chains attached to Fyrus's legs and pull. This causes Fyrus to fall over. Afterward, the jewel on his forehead becomes vulnerable and Link can attack with his Sword. When Fyrus finally recovers, he proceeds to emit a wave of fire that can damage Link, who must be sure to get as far away from him as possible after attacking.

An alternate way to defeat him is to shoot his forehead's gem and then wait until he calms down, then shoot him again, and repeat. Eventually he will fall down and can be instantly defeated with the finishing blow. This strategy takes longer and uses more Arrows.

Once Fyrus is defeated, the Twilight matter from his altered form fuses into one piece, creating the second Fused Shadow. Link is able to look upon a confused Darbus as the Goron returns to his normal self, completely unaware of what has just happened. Link is also awarded with a Heart Container for his efforts.

Trivia

 * Fyrus was the first boss revealed for Twilight Princess; he was present in the first trailer for the game.
 * The strange, boar-like helm on Fyrus's head resembles that of Ganon's face.
 * Fyrus is the only boss in Twilight Princess to have only one phase in his battle. All of the other bosses have two or more.
 * Fyrus and Blizzeta are the only bosses in Twilight Princess that are not completely destroyed after defeat. This may be because they were originally friendly beings who were possessed, whereas most of the other bosses were originally enemies.

Nomenclature
Fyrus's name is a portmanteau of Fire and Darbus, the name of Fyrus's original form.
