Fyrus

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