Argorok

Twilit Dragon: Argorok terrorized the Oocca, denizens of the City in the Sky. It appears as a black armored red dragon and causes mischief in a manner reminescent of mythological dragons.

Strategy
The battle takes place when Link climbs up to the highest point of the dungeon on a flat plain with four steel grated pillars and high winds. The first thing Link must do is go to one of the pillars that are positioned around the stage. Once there, use your Double Clawshot to climb up two of the pillars that are closest to each other. Go to the highest point of the pillars and wait there until Argorok flies up to you. Target the dragon's tail and clawshot onto it. Equip your Iron Boots to increase your weight and bring Argorok down crashing into the stage. After hitting the stage, some of his armor will come off, repeat. After the two or three times, Argorok will shed off all remaining armor, exposing his skin and his new weak spot. Also, a group of Peahats will come out of the ground ascending into the air. Once again, climb up the pillars, but don't stay there. Instead, clawshot up to one of the Peahats. Argorok will fly up into the center of the Peahat circle and begin breathing fire at Link. Clawshot from one Peahat to another until Argorok stops blowing out fire, then clawshot to the Peahat right behind him while he is resting and clawshot onto his back. Slash away at the new weak spot until he shakes you off. Repeat this stategy three more times and Argorok will come crashing down dead. Be careful about the third time, Argorok will try to outsmart you by instantly changing directions, which you must also do. Once he is defeated, you will have a Heart Container and the final piece of the Mirror Shard.

Trivia
Argorok is a play on "Kargarok", the bird-like enemy that is common throughout the game.

His armored appearance somewhat resembles Ridley from the Metroid series.

In the official website, its name was mispelled as Argarok.

The battle against Argorok is similar in strategy to the boss fights against the colossi in the Team Ico game Shadow of the Colossus.
