Nyx Avatar

Nyx Avatar is technically the final boss of Persona 3, as s/he is the final enemy actually fought by the players, instead of being a scripted battle. Before becoming the Avatar it was known as Death, the harbinger of the Fall and incarnation of the Arcana that was never meant to be: Death. Because s/he went through many incarnations and separations, s/he can be recognized as any one of the following entities: Death, Ryoji Mochizuki, Pharos, and Nyx.

In battle it harnesses a total of 14 Arcanas - from the Fool to its true Arcana, Death. It shifts its Arcana through its unique skill Arcana Shift, and each time its elemental afffinities and used attacks change. Should the player set the game's difficulty on 'easy', he will tend to use weak skills such as Agilao. At his final phase, he uses two unique skills - Moonless Gown and Night Queen. The former temporarily renders all attacks to be reflected against the attacker, including Almighty attacks such as Megidolaon. The latter deals heavy damage to all opponents, while inflicting a myriad of random status efffects.
