The Demons are animals, plants or inanimated things that were enlightened in the Dao, gained their own consciousness and cultivated a humanoid body. Demons are born thanks to the incubation of worldly energy or from powerful cultivators' dao preaching and protection. While they come from many different species they are considered to be a single race.
As they came from the different species, the Demons didn't have uniform look. In most cases they are half-humans with animal head or limbs, or vice versa - half-animals with a human head/limbs.
