The Desert Baretta, also known as the ANKYLO, is an enemy in the original Final Fantasy. They are large beasts covered in bony armor that prowl the deserts of the northern continents. These creatures appear alone in the Yahnikurm Desert, and may be somewhat challenging, especially if the party attacks with magic, as it does not have any weaknesses and has a pretty high Magic Defense stat. Even though it looks physically armored, the monster has a lower Defense stat as compared to its Magic Defense, and thus it is best to focus on physical attacks. A barrage of physical attacks dealt by the entire party can easily wipe out a sole Desert Baretta. They also rarely appear outside of the town of Onrac.
They appear very often in the desert, along with Allosaurus, and they do not appear in groups. It is unknown why they drop only one gil, as it is a normal random encounter.
