Two-headed Dragon(２ヘッドドラゴン, Niheddodoragon?), also known as 2-Headed Dragon and Twinhead Dragon, is a recurring enemy in the series, mostly appearing as a boss and as a reference to its original appearance in Final Fantasy III.
Two-Headed Dragon is a boss fought at Earthgift Shrine, exclusive in the Game Boy Advance and later remakes. It fights only using physical attacks, and is the easiest of the bosses in Earthgift Shrine. Defeating it yields the Bard's Tunic.
Twinhead Dragon is a boss fought at B12 of the Depths during the final Tale, and fights using powerful physical attacks as well as level 3 elemental spells and Constrict. Upon defeat, it will drop the Holy Lance.
