Caa-Porá
This is a fantastic creature from the traditions of the subtropical jungles on the border between Argentina, Brazil, and Paraguay. It can appear as a beautiful naked woman who drives mad any men who venture deep into the jungle.
But at other times, Caa-Porá can appear in the guise of a dark, evil man who beats hunters and their dogs, preventing them from working. And at still other times, it appears in the form of a giant man covered in hair who devours the animals that hunters have killed.
