Notes:

The title's meant literally, this character's based off the Behemoth monsters from the Final Fantasy series.
No word on Meteor spells or any of the other things Behemoths are known for, as this character has no name, background, etc.

My favorite parts of the design are some of the smaller touches.
In specific, the hoof shape added to the steel-toed boots and shoulder spike.
The little bit of fluff to the underside of the tail is nice, as well.
