>>24565697Jersey Devil, Mothman, Big Foot, Champ, and some lizard thing that I forgot the name of. There's a lot of other regional ones too, but those are a couple of the well known ones.
That's not even mentioning the plethora of specific hauntings. America's got really interesting history and myth/urban legends, but so much of it is obscured behind the fact that each state is so different and things tend to stay local. Something that the Japanese really wouldn't easily know outside of Bigfoot and maybe Mothman. Shin Megami Tensei actually has a couple of demons that are based on American urban legends. It's cool shit, pic related is the Jersey Devil in Soul Hackers.
