A Cosmic Entity
that is roughly as powerful as the setting's monotheistic God
-- or, in non-monotheistic settings, the God of Gods
equivalent -- and is His antithesis
, i.e. evil, destructive, corrupting, etc... unless God Is Evil
, and therefore the Anti-God would be good
. The relationship between the two may be one of harmony or of rivalry.
If only two gods exist, and both are antithetical opposites of each other, then chances are the God of Evil
would be the Anti-God. Note however, that not every God of Evil
is the Anti-God; rough equality of power (or, alternatively, importance in the greater scheme of cosmic order) between the two opposite entities is mandatory at the minimum, thus why e.g. Morgoth
is not The Anti-God to Eru Ilúvatar
despite being the God of Evil
Several modern depictions of Satan elevate him
from being merely the most powerful and/or influential of all demons/devils or Fallen Angels
to this trope. Characters based on Satan are also portrayed this way.
Not to be confused with A God I Am Not
- Tash in The Chronicles of Narnia, as he is literally the antithesis of Aslan. All that is vile and evil is Tash's domain, all that is noble and good is Aslan's.
- The Dark One of The Wheel of Time, equal and opposite of the Creator, embodiment of evil, destruction, chaos, and paradox, who takes the form of an infinite void and a voice that speaks in ALL CAPS.
- Subverted in Mistborn. Ruin is initially presented as this to Preservation, two gods who are complimentary opposites and together created the world; when the balance is thrown off between them, bad things happen (in the books, the balance gets thrown too far Ruin's way, nearly leading to The End of the World as We Know It). However, later works set in The Cosmere show that Ruin and Preservation themselves were only two fragments of a much more powerful god called Adonalsium- sixteen such fragments (called Shards) exist in total, and none of them can properly be called God or Anti-God.
- One of the major religions of A Song of Ice and Fire feature two gods, constantly at war: the fire god R'hllor, Lord of Light and Shadows, who likes having people burned as sacrifice to him, but is a pretty good god (for a Crapsack World). Then you have the Great Other, his enemy, lord of cold and darkness, who represents all evil in the world. This religion also denounce all other gods to be lesser demons, servants of the Great Other.
- The Dark Tower has The Crimson King, who is personification of evil in the multiverse, yet not very sane or powerful, and he plans on knocking down the Dark Tower, which would destroy the multiverse in general.
- This is called bitheism/ditheism/duotheism in Real Life, with bitheism being the "harmonious duality" type, ditheism denoting "eternal rivals" type, and "duotheism" denoting the situation where the two deities are of opposite genders.
- Zoroastrianism is an example, with its two primary deities Ahura Mazda (the equivalent of the monotheistic God of Abrahamic religions, also known as Ormazd), and his antithesis Angra Mainyu (aka Ahriman); here, Ahura Mazda is a God of Gods-type Top God, with the lesser gods under him being akin to the Abrahamic religions' angels.
- When it's specifically the Abrahamic God and Devil who are opposed, that is the "Manichaean heresy". It's heretical because the orthodox Abrahamic position is that God has no equal, opposite or otherwise. God is singularly responsible for creating the totality of existence, including the Devil, so the Devil cannot possibly oppose Him on an equal footing like he wants.
- In the Castlevania series, Dracula is eventually revealed to be the antithetical opposite to God as part of the Balance Between Good and Evil. While God's actual degree of power has not been demonstrated or elaborated upon, Dracula himself is the most powerful being to be ever shown in the series, going as far as to have the Grim Reaper himself as his own right-hand man.
- Oracle Of Tao has the Ancient One, a hooded ghoul who rules the void. God isn't really good or evil, but rather has Blue and Orange Morality of some sort. The Ancient One, on the other hand seems to be merely territorial, destroying whatever is nearby. God is ruler of all existence, the Ancient One is ruler of nonexistence. Supposedly the two are equally powerful, but this may be an Informed Attribute, because God's power is never tested in battle, and there are stronger enemies out there.
- Cosmos and Chaos in Dissidia: Final Fantasy are such a pair. No points for guessing which is good and which is bad.
- Sithis, the deity the Dark Brotherhood worships in The Elder Scrolls series, is what's left of Padomay, who was the original Anti-God, dark twin of the progenitor God of Gods Anu and the progenitor of the Daedra.
