Tlaltecuhtli, is a pre-Columbian Mesoamerican deity figure, identified from sculpture and iconography dating to the Late Postclassic period of Mesoamerican chronology (ca. 1200–1519), primarily among the Mexica (Aztec) and other Nahuatl-speaking cultures. Tlaltecuhtli is also known from several post-conquest manuscripts that surveyed Mexica mythology and belief systems, such as the Histtoyre du méchique compiled in the mid-16th century.
In one of the Mexica creation accounts, Tlaltecuhtli is described as a sea monster who dwelled in the ocean after the fourth Great Flood, an embodiment of the raging chaos before creation. Quetzalcoatl and Tezcatlipoca, in the form of serpents, tore her in half, throwing half upwards to create the sky and stars and leaving the other half to become the land of the earth. She remained alive, however, and demanded human blood.
Although the deity's name is a masculine form in the Nahuatl language, most representations of Tlaltecuhtli exhibit distinctly female characteristics, and the figure is often posed in the characteristic position of a woman giving birth. She is sometimes associated with Cihuacoatl, Tonantzin and Tonatiuh.
Tlaltecuhtli is a boss in the Challenge QuestTake Out A Pesky Demon, where she's blocking off Club Milton and both trapping a human there and keeping him from smuggling stuff out. Her only bit of dialogue is revealing her desire to fix her body by consuming Reds before the battle, dying in silence.
