“The Winchesters” only showed viewers a couple of basic sides of the soucouyant. In the episode, she’s impervious to most attacks and has the ability to scorch her victims. Additionally, the hunters explain that defeating her requires a stake through the heart or a decapitation, similar to a more traditional vampire. Simply chopping off her hand doesn’t work, as the show’s Scooby gang learned the hard way.
Per Caribbean Reads, there are different versions of the soucouyant in the native folklore. Some people believe that she’s a hideous hag, similar to her appearance in Episode 6 of “The Winchesters.” However, others are under the impression that she’s a beautiful woman with great seduction skills. One thing that is consistent in most versions, though, is that she can turn into a ball of fire and fly.
According to Caribbean Reads, it’s believed by some that the creature originated in Africa and made its way to its renowned continent with other travelers back in the day. Regardless of where the monster came from, you don’t want to get on its bad side.
