Well... technically they're humanoid demons... They have two legs, a head, an.. arm each? There's a few other bits, uh, missing as well.
(Proceed with caution if investigating, they live in Hell and look gross and don't bother with clothes.)
I see a lot of demon/angel characters, but what I really want to see is the terrifying or elegant creatures of the dark and light. Got a demon that has the form or an animal? cool. An angel that looks like whatever the frolicking frick Galeem is? awesome. This also works the other way around. have a demon that looks like some abstract horror? or an angel that looks like some type of bird or fish, etc, that's also cool. If it doesn't just look like a human with wings/horns and a tail, then I'd love to see it.
Also, here's an angel of mine: https://toyhou.se/2219709.amorous-pronoia-
The Herald is a nonhuman archangel I saw in a dream! He has no actual body, that's just a cloth underneath his head.
Nonhuman demons are a common thing for me (a lot of the ones I have documented are very old!), and it's only recently that I've had a humanoid demon around.
