Gyorg

Gyorgs are large carnivorous fish. Originally, they were depicted as an individual, though later they are established as a species.

The Legend of Zelda: Majora's Mask
In The Legend of Zelda: Majora's Mask, Gargantuan Masked Fish: Gyorg is the boss of the Great Bay Temple. It is depicted as a horned, magenta, piranha-like fish. When Link drops into its room, the camera has a point-of-view shot for it swimming in the water, potentially as a reference to  or a callback to Morpha. It then leaps out of the water over the platform, briefly stopping in place for the boss subtitles to label it. In battle, it swims about in the water, occasionally bashing the platform to try and knock Link in, or leaping over to try and bite at him. If Link falls in, it will attempt to bite him, damaging him while carrying him around the room, eventually dropping him. Gyorg can be stunned with a projectile, and then shocked with Zora Link's electrical field. After it gets back up, Link will need to quickly swim back to the platform, lest it bite him. After a while, it will release a school of smaller, similarly-colored fish, possibly its babies. They will also attempt to damage him. After it is defeated, it will bash against a wall, draining the water, while it flops about and shrinks, eventually leaving behind Gyorg's Remains.

In The Legend of Zelda: Majora's Mask 3D, Gyorg is redesigned enough that it received new artwork. It now has a gray bony front resembling that of a Dodongo, and its fin bones are longer. Like the other bosses in this version, it shows a large, out-of-place eye that can be damaged when vulnerable. Additionally, an extra phase of the battle is added, where Gyorg destroys the platform in the center, causing Link to have to battle it entirely in the water as Zora Link.

The Legend of Zelda: The Wind Waker
In The Legend of Zelda: The Wind Waker, Gyorgs are much smaller, and are depicted as purple shark-like fish with rock-like protrusions on their noses they use to bash boats with. They are encountered commonly on the Great Sea, where they will rapidly swim ahead of the King of Red Lions before turning around to bash into him, occasionally leaping from the water as well. They can be defeated with the cannon.

The Legend of Zelda: The Minish Cap
In The Legend of Zelda: The Minish Cap, a Gyorg Pair is the boss of the Palace of Winds. They are depicted as being giant, multiple-eyed manta rays capable of flight. The larger female is red and has eight eyes at the front of her body, and the smaller male is blue and has four eyes, with each being on a different corner of his body. Link must alternate between riding on the back of each and attacking their eyes, with them shooting projectiles at him and attacking with their long, clubbed tails. Green baby Gyorgs fly across the screen in large arrays as well, but are quite weak.

The Legend of Zelda: Phantom Hourglass
In The Legend of Zelda: Phantom Hourglass, Gyorgs look and act roughly the same as they do in The Wind Waker. They are among the most aggressive enemies encountered on the sea in this game.
