The Thanatos is an enemy from Final Fantasy III. She can be found in the Ancients' Maze. She is a moderate threat in the NES version, as she can only inflict upwards to 700 damage with her physical attack and inflict Petrify with Breakga. However, she is a bit more difficult in the DS version due to her ability to now attack twice in a row. Physical attacks are still the best way to go in defeating them.
