Behemoth

Behemoth is a powerful Heartless

The Behemoth was one of three powerful Heartless released by the final Keyhole. The other two were Phantom and Kurt Zisa. While the other two left to destroy other worlds, the Behemoth remained and guarded the keyhole.

There were multiple Behemoths; although the main Behemoth was found in the Radiant Garden, other Behemoths were found in the Olympus Colosseum and End of the World. They were all battled the same, though. Sora sometimes battled Destroyed and Arch variants.
