This unnamed Dragon, often referred to by its class name of Fire Dragon, is the final boss of Fire Emblem: The Blazing Blade. It was one of the three dragons who were summoned out of the Dragon's Gate by Nergal, but was the only one that survived a charged ice attack from a revived Ninian, although it was greatly weakened in the process. It uses a unique Flametongue weapon.
It has 3 spaces of attack. Oddly enough, despite the fact that it has 9 spaces of movement, it remains stationary. It should be noted that the Dragon always deals a fixed 37 damage in Normal Mode and 38-40 damage in Hard Mode. It is possible to kill it in one hit with Nils boosting either Athos or Canas, providing he reached 29 magic, with Filla's Might and having the latter strike a critical hit with Luna. This can also be done with a maxed out Eliwood if he has Durandal equipped.
