Atepexolotl

Atepexolotl or the beast of the city, was a feature of a prophecy spoken about Momacani by his mentor, Ocotochtli.

"You will make war with the beast of the city, and the people will be grateful, and in this way will your fame be fortified."

The prophecy came to a head when Yaotl placed Todd Calavero into a deep sleep and in an attempt to prevent him from waking up his dream of San Antonio, Texas came to life, chasing him into Tlalocan where Momacani eventually bests it. (PROSE: Against Nature)
