Earth Dragon (アースドラゴン, Āsu Doragon?), also known as Earth Tyrant, Earth Raptor, Dirt Drgn, and DirtDrgn, is a recurring enemy in the series. As its name suggests, it a dragon of the Earth-elemental type, and thus attacks using powerful Earth-elemental abilities.
Earth Dragon is a boss fought at the Opera House in the World of Ruin, and refought in the Dragons' Den in the Game Boy Advance and later releases of the game. In the Opera House, it fights using primarily Earth-elemental attacks such as Quake, Magnitude 8, and Landslide, and counters the Float status with 50 Gs. In the second battle, it instead primarily attacks with a barrage of powerful physical attacks, and if any characters are under Float, it will counter with 50 Gs, Magnitude 8, and Quake in succession.
Earth Tyrant is an optional boss fought at the Dalmasca Westersand - Wyrm's Nest, fighting using primarily physical attacks that can inflict Poison in addition to Screwtail and Sonic Fangs. It has a tremendous amount of HP, and when under 50% Max HP, will increase its Defense, prolonging the battle.

Dragon types in Final Fantasy are typically inspired by Dungeons & Dragons. Lung dragons in Dungeons & Dragons are based upon Chinese and Japanese dragons, and are spirits that embody and empower aspects of nature rather than being normal, physical creatures. Most lung dragons don't have breath weapons, but use spell-like abilities.
