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 Arcana - 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 myriad random status effects. Nyx Avatar is known to bring about the Fall which means to end the world.

Meaning
Like the Shadow Arcana, the Nyx Avatar represents the inverse interpretation of the Death Arcana. While the Death Arcana represents regeneration, deep change, and cycles, the inverse Death Arcana's meaning is purely death, doom, and an end to something.

Stats
It is crucial to note that this boss can attack twice each turn (thrice if it's attack strikes critically or a weakness).

Fool
During this stage, Nyx will not choose to attack, instead simply "smiling arrogantly" until this stage's HP is depleted. Because of this, it is largely recommended that the player NOT use any SP for this stage in order to preserve it for the next stage, when the real fight begins.

Magician
This stage specializes in Fire magic.

Priestess
This stage specializes in Ice magic.

Empress
This stage specializes in Wind magic.

Emperor
This stage specializes in Lightning magic.

Hierophant
This stage uses Rebellion and Revolution to raise its Critical rate, and dealing massive damage to any party members that are knocked down via Vile Assault.

Lovers
This stage specializes in casting Charm and Panic status ailments.

Chariot
This stage tends to use its 2 turns to cast Power Charge, followed by any of its strong physical attacks. Its immunity to physical attacks protect it against Tetrakarn/Attack Mirrors as well.

Justice
This stage specializes in Light magic.

Hermit
This stage is more defensively oriented, using Tetrakarn and Makarakarn to reflect attacks while casting status ailments that are boosted via Foul Breath.

Fortune
This stage specializes in all four elemental spells, and is immune to each of them as well.

Strength
This stage, like the Chariot form, specializes in Power Charged physical skills, though with Rakunda added in to squeeze out extra damage.

Hanged Man
This stage specializes in Dark magic, and on occasion throws out Mind Charged Megidolas as well.

Death
This phase knows all -dynes spells, stat decrease spells, charges, spells that inflict panic, poison, and fear to all enemies, elemental break spells, and Moonless Gown, which reflects all attacks and Night Queen, which deals high Almighty damage and can inflict random ailments.
