مون فاکای

Once known as Lunar Nicholai, he became Moon Face when he was transformed into a Homunculus. While playing a minor role in the series, he's easily remembered due to his obvious characteristics. Notably, his crescent moon shaped head. He speaks with enthusiasm with a catchphrase "Moon!"

[Spoiler: His Busou Renkin's power is called Satellite 30, duplicating him into 30 individual beings, one for each phase of the moon. As it suggests, each being's face is of a different lunar phase. From Full Moon, to new New Moon having no physical head at all.

If some forms are defeated, he can simply create more.]
