The manananggal is a mythical creature of the Philippines. It resembles a Western vampire, as an evil, man-eating monster or witch.
It is described as being a hideous, scary vampire-like creature, capable of severing its upper torso in order to fly into the night with huge bat-like wings to prey on unsuspecting, pregnant women in their homes; using an elongated proboscis-like tongue, it sucks the hearts of fetuses or the blood of an unsuspecting, sleeping victim. The severed lower torso is left standing, and it is said to be the more vulnerable of the two halves.
(i just made it not so scary ;D)
