Ebony Dragon

The Ebony Dragon is a monster encountered randomly during a New Moon in the Lunarian's Tale in Final Fantasy IV: The After Years. It is a strong enemy and is found in the Lunar Path, and also in the Subterrane of the True Moon in the Final Tale. It drops the Ebony Tail, a rare item that can exchanged for a valuable item with the tail collector on the True Moon.

The Lunarian's Tale
The Ebony Dragon nearly counters every attack, so it is best to be at full HP before fighting it. It is very weak to Holy, and should take over 8000+ damage from the spell. If Golbez and Fusoya are at their capped levels for their tale, this fight shouldn't be too difficult. Golbez should also attack with the Defender, if he has it.

Final Tale
Another version, as well as the other enemies that hold tails, appears randomly in the Subterrane during the final tale of the game.
