The Destroyed Behemoth is a massive, quadrupedal Heartless. Its body is predominantly slate grey in color, but its back and all four of its legs are decorated by an orange flame pattern. Each of the Destroyed Behemoth's legs have two toes with green claws. It has two large, curved tusks sprouting from its lower jaw that are red on their upper half and slate grey on their lower half. The Destroyed Behemoth's conical, blue horn is on its forehead. Like most other Heartless, it has yellow eyes and a jagged maw. Its Heartless emblem is on its chest.
The Destroyed Behemoth's name is a reference to its large size and its destructive nature. In the Final Fantasy series, a Behemoth is a large, horned creature with massive strength.
Just as the original Behemoth, its weakness is its horn, and it is immune to all elemental spells. To take it down, cast Aeroga on yourself, get on its back, and attack the horn incessantly!
If you cannot evade the bolts of lightning by using Dodge Roll on time, keep having Aeroga on. This can at least reduce the damage. Rather than using Ethers or MP-restoring items, make use of the MP generated with every hit inflicted on the Destroyed Behemoth.
