Anchanchu

The anchanchu, abchanchu or anchancho is a legendary Andean vampire largely originating from the Aymara region of Bolivia. It shapeshifts into the form of a helpless, elderly traveler, a rich Aymara woman with gold teeth, a seductive gringa, or a monstrous animal. When a passerby offers to help, the anchanchu victimizes them and drinks their blood, causing them to die of blood loss or disease. The anchanchu is the most feared evil being among the Aymara people due to its lethality. The anchanchu legend is also shared among the Peruvian Aymara community, though the Peruvian version is considerably different. In Peru, the anchanchu is a duende, similar to a dwarf. Called Muki or Muqui, it lives underground and has a penchant for gold. An analogous deity is the Uru god Tiw, the protector of mines, rivers and lakes. This deity's name was transformed to El Tío in Spanish.
