Arch Behemoth

The Arch Behemoth (アークベヒーモス) is an enemy exclusive to Kingdom Hearts: Final Mix.

It is a blue version of the original Behemoth, and has a flame design marked onto its body. Arch Behemoths appear multiple times throughout the End of the World, although they aren't as strong as a normal Behemoth. In the original Kingdom Hearts, normal Behemoths occupied the area instead, but this was changed, with the Arch Behemoth receiving its own entry in Jiminy's Journal.

Strategies
At the start of the battle, they will most likely begin with loading up the orb that he launches in the sky. If you want to avoid getting hit by the orbs that fall down, try to sneak under it after it has launched the orbs in the sky. After that, you'll want to focus on getting on it's back and repeatedly attacking its horn. If it is stunned, do about 2 combos and then back away, for he will cast Lightning that will hurt alot. If you get away from him, this will miss. Keep doing this and eventually you'll beat him. Cast Aero if you can't avoid getting hit.
