The Behemoth is an enemy in Final Fantasy IX found in Memoria as a regular enemy. A Behemoth can also be fought in the Treno weapon shop during endgame for a Circlet. It has the same stats as regular Behemoths, but no Experience, gil, or other items are rewarded for defeating it. In the Steam version of the game, defeating the Behemoth in the weapon shop with Dagger earns the achievement Dragon Lady.
Behemoth is especially dangerous because it can counter most attacks with Meteor Counter, which works like a Meteor spell. Behemoth is not immune to negative statuses.
Attacks like Blizzaga, Flare, and Thievery (if built up to 9,999 damage) all work well. Inflicting statuses, such as Instant Death, Heat, and Freeze, help tremendously. Like every enemy vulnerable to Sleep, Quina's Night will put it to Sleep. As long as the party has Insomniac, this will disable the Behemoth and prevent it from using Meteor Counter as long as it's not awoken with a physical attack. Vivi's Death and Dagger's summon Odin can kill it in one hit.
Location: Treno, Card Stadium "Beast Master Gilbert"
Behemoth is a beast mentioned in Job 40:15–24. In addition to mythological creatures, it is likened to elephants, hippos, rhinos, and bison. Metaphorically, the term behemoth denotes "an extremely large or powerful entity."
