There was a recent episode in “Grimm”, a TV show in the genre of urban fantasy’ish which focuses on folk tales and the entities that comes along it, and this episode focuses on one of the popular folk monsters in the Philippines, the Aswang (or aka TikTik).
In the show, the “Aswang” is a monster that likes to eat unborn babies from the belly of the pregnant wife – they do it to as a way to renew their life energy and achieve pseudo immortality.
In the folk tales told to us by the elders, Aswangs are just general term for monsters in the Philippines, and they are just monsters who follow their nature. Actually, while the modus operandi is the same in the TV show as it is in the folk tales, their actual appearance is quite different.
The monster that was portrayed in Grimm, we actually specifically call a Mananangal and for the most part, in our folk tradition, a demonic women who can separate her upper body from her lower torso, grow bat wings, and fly around seeking victims – their favorites are unborn babies.
This monster is so popular in the Philippines that someone actually tried to make a documentary out of it. Even in my family, there has been some talks that we’ve had run in against them (I’ve never met one TBH so I can’t verify if this is true or not).
As well, apparently, these is an island in the middle parts of the Philippines where they say is filled with all kinds of monsters like the one mentioned above. (Something I’ve hoped to stumble upon one of these days when I return down there).
