Riko Kupernreich is also completely insane to the point of having a God complex, having infused a powerful mystic gem into his belly he grew to great size (for a moogle anyway) and proclaimed himself the "Alpha and Omega" of moogle kind before attacking the adventurers in a spectacular display of megalomania: seeking to kill them all so as to rule the entire world. Riko Kupernreich is, so far, the only moogle to be portrayed as a major villain in the series and is thus a unique and surprisingly powerful boss to face in battle.
