The Shark is a character who can be found exclusively as a boss in Kingdom Hearts.
The Shark is a rotund, yellow-eyed 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.
The Shark 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.
The Shark 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, the shark no longer stalks the sunken ship, leaving it to be infested by the Heartless.
The Shark, a.k.a. Glut, originated from the Disney 1989 movie, The Little Mermaid. He appears attempting to kill Ariel and Flounder. He pursues them across the Sunken Ship, destroying it in the process. However, he is defeated when he gets his head stuck in an anchor and is not seen through the rest of the film.
