According to the Japanese folklore, the Jorōgumo is a magic, 400 year old giant spider, that can change its appearance into that of a beautiful woman. She seduces young handsome men, wraps them up in her webs and eats them.
This supernatural creature from the Nicaraguan folklore is a shapeshifter. It typically takes the form of an attractive long haired woman who seduces drunken and unfaithful men before revealing her true face: a Horse Skull. The words she speaks to these men are so horrific that the victim goes insane instantaneously.
