Aswang is a new unit that is introduced in Metal Slug Attack.
A self proclaimed "vampire", Aswang frequented a certain town with her bat familiars in tow.
One day, she encountered Vatn, who was hired by the town to drive her out. Vatn severely wounded her with silver bullets (causing her to become allergic to metal in the process), though she survived. She is searching for Vatn so that she can exact revenge on him.
- Her name was derived from the shapeshifting monster in Filipino folktale with the same name usually possessing a combination of the traits of either a vampire, a ghoul, a warlock/witch, or different species of werebeast, or even all of them together.
- She bears a resemblance to Eliza from Tekken series.
