Camazotz

In ancient Mayan mythology Camazotz was an enormous bat-god who presided over death and sacrifice.

Overview
According to the eighteenth-century text the Popol Vuh, a pair of heroic twins were invited into the underworld to play a ball game against the Mayan lords of death. Whilst there, they were required to spend a night in the House of Bats, where they were predictably assaulted by the resident bats. To avoid ending up as meat for the flying predators, the two squeezed themselves into their blowpipes, but when one stuck his head out to see if the sun had risen, it was promptly lopped off and carried away by Camazotz to be used by the gods as a ball in their next game.
