The Dread Pyramid of Itzilichlitlichlitzl is the site where the Middleman and Sensei Ping confronted El Maestro De Ceremonies. Located in the jungles of Mexico, it was the "secret" headquarters of the Mexican Luchadores, although Ida knew both what and where it was. Wendy Watson infiltrated the Dread Pyramid by parachuting in from the Middlejet.
The Middleman defeated at least seventy-five of Cien Mascaras, but was finally subdued. After Wendy freed Sensei Ping, the Sensei killed the remaining Cien Mascaras and all the Luchadores.
