Camazotz

Camazotz is a demon in Maya mythology. Camazotz takes the form of a giant bat and resides in the House of Bats in the Mayan underworld.

Destroying the Human Race
According to Mayan myth, the gods protected the Mayans keeping all demons confined to the underworld. In return, the gods required an array of human sacrifices. When the people began to resist the gods' demands, the gods punished humans by releasing Camazotz, wiping out the human race. The gods then created a new human race that would be more obedient.

Hunahpu and Xbalanque
The hero twins Hunahpu and Xbalanque entered the House of Bats intending to destroy Camazotz. After Camazotz tears Hunahpu's head from his body, Xbalunque saves his brother by replacing his head with a pumpkin. Later, Hunahpu retrieves his head, and the two twins defeat Camazotz.
