Profile
Nyx Avatar is the final boss of Persona 3, as it is the final enemy actually fought by SEES, 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 it went through many incarnations and separations, Nyx can be recognized as any one of the following entities: Death, Ryoji Mochizuki, and Pharos.

In battle, it harnesses a total of 14 Arcanas - from the Fool to its true Arcana, Death. It changes its Arcana using its unique skill Arcana Shift, and each time its elemental affinities and used attacks change. 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 effects.

Trivia

 * Though using Ryoji Mochizuki as its Avatar, SEES Still refers to Nyx and its Avatar as "She" in both "The Journey" and "The Answer".
