Amon (アモン) or Amaimon (アマイモン) is a demon in the series.
Amon (also spelled Aamon or Amaymon, along with many other variations) is a Marquis of Hell. He is the seventh of the 72 Goetic demons who governs forty infernal legions.
He appears as a wolf with a snake's tail who can breathe fire, or as a man with dog's teeth who is situated inside of a raven, or as a raven-headed man. Collin de Plancy took the artistic liberty of compressing Amon's two forms into one with the head of a dog-teethed raven, the body of a wolf, and a snake tail in place of its back legs. At the command of a mage, Amon may take the shape of man with a raven's head, having teeth of a canine. He tells of all things past and future.
He procures love and reconciles controversies between friends and foes. Some demonologists have associated his name with the Egyptian god Amun or with the god Ba‘al Hammon of Carthage.
As Amaymon or Amoymon he is said to be a Prince of Hell and King of either the West or East. Asmodeus and sometimes Gaap are said to be his servants. A silver ring is required to be worn on the middle finger when summoning him, as his deadly breath will kill the summoner otherwise.
Amon appears in the World of Sloth to the player asking if Tamaki Uchida was looking for Akira Miyamoto in the school halls. If the player says "Yes", Amon joins the group if Akira have been defeated earlier, if not, Amon will battle the party. While controlling Ideo Hazama, Amon will give him a chance for redemption, and joins the party.
Shin Megami Tensei IV DEMONIC GENE
A demon who appears before Gina in Naraku offering her power. He is killed by Walter in the Domain he sets up, but bites him and warns that the infection will make him hunger for power and seek out the power of demons, dissipating afterwards. The infection grants Walter inhuman strength and regeneration, spawning mouths, hands, arms, and tentacles from amputated limbs or just upon Walters body, and causing him to see people as demons. One such case of illusions is the three Amaimons in chapter 2, which are actually normal humans.
Amon must first be revived as a zombie before eventually being brought to life.
