No. The art team was inspired by demons.

You hardly need to look at a 2 year old "what if?" post, as of SB we know:
✔ Au Ra are warmblooded
✔ Au Ra have live births/breasts
✔ Voidsent are mutated denizens of the 13th world

They're mammals.

Who said voidsent can't have breasts or bear children? Or that they aren't warmblooded?

The world needs more monster girl waifus

I agree 100%
