The Shark

Glut is a character who can be found exclusively as a boss in Kingdom Hearts and Kingdom Hearts Final Mix. He first appeared in Disney's The Little Mermaid.

Kingdom Hearts
Glut is normally found swimming around the Sunken Ship area. He is considered an enemy at first, as the player can escape fighting him, but he has to be defeated later to enter Ursula's lair. He attacks randomly, and can do a great deal of damage. After Ursula is defeated, Glut no longer stalks the sunken ship, leaving it to be infested by the Heartless.

Appearance
Glut is a rotund, yellow-eyed shark seemingly based off of a great white shark. The top half of his body is navy blue, while the underside is a light blue color. He has three gill slits on either side of his body and a small nick in his tail fin. Glut only has one dorsal fin, without the second, smaller dorsal fin further down his body like most sharks. While his teeth are the typical triangular shape of a great white, they seem to lack serrations and, most notably, there is only one row of teeth in his mouth, as opposed to the multiple, rotating rows of teeth common to all sharks.

Trivia

 * Glut is neither named nor mentioned in the actual script for Kingdom Hearts. He is simply called "shark" in the Ultimania and BradyGames guides, but its name is given as "Glut" in official Disney records.
 * Glut is one of only eight enemies in Kingdom Hearts who do not have entries in Jiminy's Journal (the others being AntiSora, Bit Sniper, the Cave of Wonders Guardian, Chernabog, the Crank Tower, Shadow Sora, and World of Chaos).
