Behemoth

The Behemoth is a boss from Kingdom Hearts.

The Behemoth is one of the three demonic Heartless released by the Hollow Bastion keyhole. The other two are the Clock Tower Phantom and Kurt Zisa. While the other two left to destroy other worlds, the Behemoth remained and guarded the keyhole.

There are multiple Behemoths; although the main Behemoth is the second boss of Hollow Bastion, other Behemoths may be found in the Olympus Colosseum and End of the World. They may all be battled the same, though.

Behemoths bear an uncanny resemblance to the Groundshaker in fighting style. Originally, fans believed that the Groundshaker would actually be a Behemoth.
