Stories where all humans are demon/angel hybrids?

[marshmallow]

Diablo 3 spoilers, I guess:

In the upcoming Diablo 3 (and current Diablo books) the human origin story is that the demoness Lilith and Arch Angel Inarius fell in love and gave birth to the human race. All humans are demon/angel hybrids with the potential to be stronger than either side, which is why the angels and demons are fighting over our souls in the first place. And the Worldstone artifact destroyed at the end of Diablo 2 was put in place to dampen human potential in case we got any funny ideas about turning against both sides and becoming independent.
I like it even though it sounds cliche. But I’m failing to think of other works with this trope. There are tons of individual demon/angel or god/human hybrids, including ones from ancient myths. But usually humans as a whole are specifically created by a good god and then maybe they’re corrupted or fall from grace later on. Or their creation was an accident or side effect of some other process. But then again I don’t read a lot of fantasy fiction. Any other examples?

It’s not exactly what you’re looking for as it’s only the title character, but the closest I can think of is the Preacher comics, where he is possessed by an angel/demon hybrid but retains his free will. It does contain the “may be stronger than both sides” trope, though.

Not all humans, but there’s a demon-angel-human hybrid in The Mortal Instruments series.

Sounds like a Go Nagai theme, mainly in Mao Dante & the various versions of Devilman.

Actually, it sounds like the sort of thing one would find in Japanese fantasy more than western, though angels and demons as such are relatively western.

While it’s sci-fi not fantasy, A Plague of Demons seems to qualify:

A dichotomy came into being. All across the spectrum of reality, a fissure appeared. Existence segregated itself into two categories, inherently opposed. Conflict renewed; pressure built; expansion resumed. Again, life was on the march toward its unimagined destiny.

On every world where the opposed forces met, the struggle was joined. Each force knew the other, instinctively recognized the ancient enemy. Each side called itself by a name, and the antagonist by another.

One name was Good, and the other Evil.

A variety of symbols came into being, and across the worlds, the struggle swayed, reaching ever outward . . .

And a time came on a remote, isolated world, when traitorous Good met treacherous Evil and joined, against all nature, in a new formula of existence. Now, in this unholy amalgam, the ancient drives met and mingled, fought and struck a balance. A transcendent value-scale evolved—new abilities, unheard-of in the galaxy; an empathy possible only to a monstrous hybrid; an unnatural negation of the primal drive, a perversion of that terrible energy into new channels. Under the stimulus of internal stresses, minds of undreamed-of power sprang into being. At every level from the cellular upward, death conflicted with life; sloth with vaulting ambition; greed with instinct for asceticism. And out of the synthesis of opposites, a cancerous growth called Beauty came into being; obscene antisurvival concepts named Loyalty, Courage, Justice were born into the universe.

Wherever the elemental Purities encountered this monstrous hybrid, a battle of extermination was joined. Good could compromise with Evil, but neither could meet with the half-breed, Art. A new war raged across the minor galaxy and left annihilation in its wake.

Wild C.A.T.S. comic by Jim Lee might qualify. The team are fighting as part of a war between the Kherubim and the Daemonites on earth. The team get their various powers because they are all Kherubim ‘half breeds’.

The difference is, the Kherubim and Daemonites are both alien races, but as this war has rages for centuries, I think they are supposed to be the inspiration for angels and demons in the bible.

It’s implied that this is the case for modern humans in Madeline L’Engle’s Many Waters, as only the children of angels are over four foot tall. And one group of angels is implied to be demons.
