Aswang is an umbrella term for different shape-moving detestable animals in Filipino legends, for example, vampires, devils, witches, viscera suckers, and werebeasts (generally canines, felines, pigs). The Aswang is the subject of a wide assortment of fantasies, stories, expressions, and movies, as it is notable all through the Philippines. Spanish homesteaders noticed that the Aswang was the most dreaded among the legendary animals of the Philippines, even in the sixteenth century. In spite of the fact that with no particular thought process other than hurting others, their conduct can be deciphered as a reversal of the conventional Filipino's qualities. The Aswang is particularly famous in Visayas, southern pieces of Luzon, and parts of Mindanao, including capis.
"The 6th was called silagan, whose office it was, in the event that they saw anybody dressed in white, to detach his liver and eat it, hence causing his demise. This, similar to the first, was in the island of Catanduanes. Let nobody, in addition, think about this as a tale; on the grounds that, in Calavan, they detached in this path through the rear-end all the digestion tracts of a Spanish public accountant, who was covered in Calilaya by father Fray Juan de Mérida.
The seventh was called magtatangal, and his motivation was to show himself around evening time to numerous people, without his head or insides. In such shrewd the fiend strolled about and conveyed, or professed to convey, his head to better places; and, in the first part of the day, returned it to his body—staying, as in the past, alive. This appears to me to be a tale, albeit the locals confirm that they have seen it, in light of the fact that the demon most likely caused them so to accept. This happened in Catanduanes.
The eighth they called osuang, which is comparable to 'magician;' they say that they have seen him fly, and that he killed men and ate their tissue. This was among the Visayas Islands; among the Tagalos these didn't exist."
As indicated by Maximo Ramos, the expression "aswang" can be considered as a total term for a huge number of Filipino extraordinary animals. These animals can be coordinated into five classifications that equal animals from Western conventions. These classifications are simply the vampire, the dividing viscera sucker, the weredog, the witch, and the devil.
