Gyorgs are giant sea monsters from The Legend of Zelda games.
The Legend of Zelda: Majora's Mask
In Majora's Mask, Gyorg appears as the boss of the Great Bay Temple.
The Legend of Zelda: The Wind Waker
In The Wind Waker, Gyorgs are among several of the monsters that are found lurking in the Great Sea.
The Legend of Zelda: The Minish Cap
In The Minish Cap, two stingray-like monsters known as the Gyorg Pair are the bosses of the Palace of Winds and holders of the last element of the Great Sword.
The Gyorg's appearance has varied among different Zelda games. In The Wind Waker, Gyorgs appear as purple sharks with massive jaws and a rocky head. Also, in Majora's Mask, the Gyorg appears as a shark and fish mixture. In The Minish Cap, however, they appear as stingrays.
In Majora's Mask, Gyorg serves as the boss of Great Bay Temple, the third dungeon of the game. Gyorg is the perpatrator behind the curse of the ocean's of Great bay, resulting in the Ocean's water becoming highly murky and polluted threatening the existance of the Zora's and other aquatic life who call the sea home.
Upon Gyorg's demise the oceans are restored and the murky water that once covered it disappears. On a related note the third imprisoned Giant is also freed.
In The Wind Waker, Gyorgs were known to ram into sailboats and knock the occupants into the water. In Majora's Mask and The Minish Cap, Gyorg appears as a boss.
