Demons (悪魔?) are a key feature of the Megami Tensei franchise.
In the Megami Tensei franchise, "demon" refers to any supernatural entity that can bring harm to human beings or interfere with their lives in one way or another. This includes more conventional malevolent demons, folktale creatures, deities, and Judeo-Christian angels.
Although classified as demons, angels tend to differentiate themselves from demons, and likewise the demons view them as separate. Angels also includes demons that have submitted to God and have become His servants.
Last Bible seriesEdit
Known as monsters (魔獣) they are a race of creatures that coexist with humanity. In the first game it was the Gaia Masters who revived the extinct race, and with the exception of Mephisto sought to protect their existence.
In the Persona universe, gods and demons exist within the universal unconsciousness, which exists due to the Star Eater's influence. To resist the Star Eater's wave-like psyche, which was left on the surface after its main body became the moon, and stood as a contradiction to themselves, Earth's primitive life evolved a universal unconsciousness and the gods and demons within it. Gods and demons emerge from humans as a way of defending their psyches from the Star Eater.
Humans can also turn into demons if their psyche is destroyed, or if their Persona is forcibly removed, especially in the case of artificially-granted Personas, as happened with Shiori Miyashiro, whose metamorphosis into the demon Wendigo was documented by Takahisa Kandori and the New World Order.
Devil Children seriesEdit
Demons are entities that reside across the countless worlds that exist in the Devil Children 'verse, created alongside humans and angels by the creator goddess Hoshigami. The power, lifespan, and whether they are part of a race of demons with the same name or an individual varies from demon to demon. A demon's soul can be found as a gem or floating spirit, allowing for the demon to be resurrected using means such as Relic Fusion. Unlike other franchises, demons are implied to not be born from the belief or emotions of humanity.
Digital Devil Saga: Avatar Tuner seriesEdit
Demons are a person's true self, brought forth through the Atma virus that turns humans into avatar tuners. Some demons are able to dominate their original human personalities and take the place of their host, while others find either coexistence or an identity crisis born in others.
A staple gameplay feature of the series is the ability to negotiate with and/or recruit demons as allies and party members, usually through the use of a COMP with the Demon Summoning Program installed; many demons will request Items or Macca in exchange for their services. In some games, summoned most demons require Magnetite in order to maintain their corporeal forms; without a constant supply they will lose HP with each step.
