- “Skilosh, a notoriously violent, asexual, self-replicating species of demon, has the distasteful habit of implanting its demon spawn into the cranium of a human host.”
- ―Wesley Wyndam-Pryce[src]
Skilosh demons were a humanoid and asexual demon species demon recognizable by a fully functional third eye located on the back of their heads. They are capable of speaking human languages as well as their own.
Skilosh demons were hairless and possessed chalk-white skin, sporting two red stripes running down their foreheads to their eyes, then back behind their ears. Their blood was slimy and yellow-colored.
Skilosh reproduced by infecting human hosts with their spawn. Specifically, they injecteced their spawn into the back of host's skull using their long, forked tongues. As a result, in only an hour, the Skilosh spawn manifests in the form of a third eye located in the back of the victim's skull and connected to his/hers visual system. If the gestation was not aborted with the proper ritual, a fully grown Skilosh would burst from the host's skull, killing him or her instantly. Once hatched, the only way to slay a Skilosh was through an incantation or to hack its body into pieces.
