The Black Knight (ブラックナイト Burakku naito) is an unused class that is meant to appear in Fire Emblem: Genealogy of the Holy War. Virtually identical to the Great Knight class, the existence of the Black Knight class is only made known through its concept artwork. The main difference between this class and the Great Knight class is the fact that while the latter can only arm Axes, the Black Knight class is depicted wielding Lances in its concept artwork.
Enemy Great Knights such as Schmidt are observed to utilise a black color scheme that is identical to the Black Knight concept artwork, suggesting that they may originally have been planned to be Black Knights. This could also possibly hint at the fact that Great Knights are evolved from Black Knights.
