Manananggal

The Manananggal is a vampire-like mythical creature of the Philippines, a malevolent, man-eating and blood-sucking monster or witch.

Overview
The manananggal is described as scary, often hideous, usually depicted as female, and always capable of severing its upper torso and sprouting huge bat-like wings to fly into the night in search of its victims.

The manananggal is said to favor preying on sleeping, pregnant women, using an elongated proboscis-like tongue to suck the hearts of fetuses, or the blood of someone who is sleeping. The severed lower torso is left standing, and is the more vulnerable of the two halves.
