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!"
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.
