Xenoreaper

A xenoreaper is a species closely related to predators that is slightly larger and stronger in build. They are named because they were once thought to have killed xenomorphs, but it turns out that they never killed any since they're actually peaceful and gentle species, so they only wear the fossil skulls of, not just xenomorphs, but also other fossilzed alien skulls to scare off carnivorous creatures, including vampires. They are omnivorous and feed on the same type of food as humans. They work and live in peace with dylanusids and sapient species/beings, except vampires.
