So it turns out that and Aswang was featured in one of the Supernatural novels, but having gone through it, their version bears much more similarities to anther Filipino beast, the Busaw. Now here's one that I wasn't sure what to do with, another request.
Cyclops
Brutish ogres from Greece, presumed extinct.
Appearance: Cyclopes resemble humans, brutish and muscular. They have a naturally high muscle mass, making even the young bulky and strong. Around puberty the eyes merge together in a (reportedly very painful) process, leaving one larger eye in the center of the face. Because of this, they are unable to function in human society. Due to their inability to hide their nature, they were over hunted and are presumed an extinct species as of the mid 1300s.
Powers/Behavior: Cyclopes are brutes by nature, able to overpower almost anything with force alone. They have little in the way of abilities, though they are rather more intelligent than most would suspect. They are capable to speech and organised society, though hierarchy is based on the strongest over the weakest. They are noted to be skilled in farming, both livestock and produce.
Weaknesses: Pretty much anything. Despite their natural resilience, they're mortal creatures. Thick skin and strong bones save them from basic weapons, but a significant amount of force can incapacitate them. Alternatively, a shot to the eye will pierce the brain, resulting in instant fatality.
Yep, a bit weak, but it was a tough one. Any takers for the next? Otherwise I'm thinking something different for the next chapter.
