Twilit Kargarok

Shadow Kargaroks, also known as Twilit Kargoroks, are twilight-corrupted Kargaroks from The Legend of Zelda: Twilight Princess. They are black-gray and red, have jagged tails, and have funnel-shaped heads that resemble twilight portals. Unlike normal Kargaroks, they make noises similar to brass instruments. They are first encountered during Wolf Link and Midna's trip across the roof of Hyrule Castle to see Princess Zelda, notably before ordinary Kargaroks are encountered in the game. Some fly too far away to notice Link, but others fly closer or are perched nearby. When a Shadow Kargarok notices Link, it will fly in front of him, occasionally attacking. They can be defeated by two of Wolf Link's bites. The only time normal Link can encounter them is at the Palace of Twilight.

A specific large Shadow Kargarok is used at Lake Hylia by a Shadow Bulblin, who calls it down to use it as a mount. It normally flies out of reach, but once it dives down, Link can jump at it to bite it repeatedly, similar to a Twilit Messenger. After this is done twice, the Shadow Bulblin falls off. Once the Shadow Bulblin is defeated, Midna wrangles and tames the Shadow Kargarok, allowing Link to use it to travel up Zora's River. Later, the player must do this again to defeat four Shadow Insects flying above the river. It is later used for Plumm's minigame after it turns back into a normal Kargarok.

Trivia

 * In the Wii version of the game, the controls used for steering the large Shadow Kargarok up Zora's River are similar to what would later be used for Loftwing flight in The Legend of Zelda: Skyward Sword.
