"Origin: Mexico. The Aztec goddess of the earth. She is the wife of the hunting god Mixcoatle and mother to tribal god Huitzilopochtli. She has claws on her hands and feet and her diet consists of human meat. She also has a necklace made of human hearts and hands and wears a skirt of snakes."
"The earth mother goddess of Aztec mythology. Her name means "lady of the snake." She wears a skirt woven from snakes, so her name could also mean "she who wears the skirt of snakes." Her hands and feet are tipped by fearsome claws, and she wears a string of human heads and hearts as a necklace. She is the mother of the Aztec guardian deity Huitzilopochtli. Coatlicue is a deity of contrasting aspects. As the mother of the earth, Coatlicue gives birth to all life. On the other hand, she also takes life away from all creatures equally with her "jaws of death.""

Coatlicue appears as a field boss during the night hours in Ueno's Kuchinawa Cave and can be obtained through the Ichigaya hacked chip instance. A floor of Denshi Kairo features her as a boss-type hint that will lock players out of the next floor until they enter the numerical passcode 401.
