Mictlantecuhtli, Aztec god of the dead... God of Death and the Underworld. Mictlantecuhtli is the "Lord of Mictlan" (Lord of the Land of the Dead) and the most prominent of the Aztec gods associated with death and the underworld. He is typically depicted as a skeleton with a skull for a face. Creation/Myth Mictlantecuhtli played a crucial role in Aztec creation myths, notably the story where Quetzalcóatl descended into Mictlan to retrieve bones for creating humans.
