What if I were to tell you that there is a fan theory floating around out there that states Casper, our one and only Friendly Ghost, is actually a horrifying demonic presence from the underworld? According to a now archived Reddit post by Scotscin (linked below) this could most definitely be the case. Casper, as we all know and love, was just a child when he passed away but was held back with "unfinished business" transforming him into the transparent marshmallow legend we're all familiar with. He's joined by his uncle's Stinky, Stretch, and Fatso whom are notorious for getting enjoyment out of scarring the sh*t out of the living. Although Casper, being the opposite, wouldn't harm a soul, perhaps the way he's portrayed — a goofy, light, transparent marshmallow-looking ghost — is more the way he views himself. Maybe what we're seeing is a frightening unfriendly demonic after-being. Why else would we (the living) get petrified when we first lock eyes on him?
An interesting theory indeed...thanks for the read!
