Hecatoncheir, also known as Hekaton, is a boss in Final Fantasy III. He is found in the Cave of Shadows, guarding the Fang of Earth. He mainly uses physical attacks until low on health, when he uses Quake. In the NES version, it is highly recommended to keep casting Curaga each turn to counter Hecatoncheir's high damage, and to use the strongest available attacks that the party has. Having a Dark Knight helps tremendously in this battle.
