Argorok

Twilit Dragon: Argorok is the boss of the City in the Sky dungeon in. It terrorizes the Oocca, and wreaks havoc on the City in the Sky. Its appearance is a red dragon in black armour and causes mischief in a manner reminiscent of mythological dragons.

Strategy
The battle takes place at the highest point in the dungeon (a flat plain with four steel grated pillars and very strong winds). Link must go to one of the pillars surrounding the field and climb to the middle of one of the pillars using his Clawshot. Once there, he must wait until Argorok flies up to him and exposes his tail. Link must target its tail. Once he has a hold of it, he must equip his Iron Boots to send Argorok crashing to the ground, destroying some of his armor. After this is done roughly two times, the rest of the armor will break away and reveal a new weak spot (a gem) on his back. At this point, Peahats will burst from the ground to serve as extra Clawshot points. Link must climb to the top of the pillars and use the Peahats to Clawshot his way around the stage as Argorok breathes fire at him. Once Argorok pauses, Link must make his way around to his back and jump to the new weak point with the Clawshot. Link slashes it with his sword as the boss falls, eventually depositing the young hero on the ground again. The pattern is repeated, but Link must be careful; after the strategy is repeated twice, Argorok changes directions, blowing fire when Link least expects it. Repeating the process once more puts an end to Argorok, who spews flame all over before falling to the ground for the final time.

For his efforts, Link receives the final Mirror Shard and another Heart Container.

Hyrule Warriors
Argorok is a boss in the Palace of Twilight stage in. By talking to the Great Fairy, she can summon the Moon to drop Argorok to the ground where it can be attacked after being pulled by the Hookshot.

Trivia

 * Argorok is a play on Argo-, an archaic term for the Ancient Greeks, whose architecture the City in the Sky resembles, and -rok, a term used in the series for dragon enemies. It may also be a play on Kargarok, a similar common enemy.
 * Argorok may just be a normal Kargarok mutated by the Mirror Shard.
 * On a similar note, Argorok may possibly be related to the Aeralfos race.
 * In the official website, its name was misspelled as Argarok.
 * Argorok, as well as Blizzeta/Yeta, are the only bosses in Twilight Princess that can be seen when exploring the dungeon. If Link looks up when he is outside, he can see Argorok flying in the sky, just as he can speak with Yeta at any time in Snowpeak Ruins.
 * The first and second phases of Argorok's battle theme are the same as the first and second phases of Morpheel's, respectively. This is likely because Link must defeat Argorok the same way as Morpheel.
 * The snout of Argorok's armor bears a Triforce emblem.
