I saw the below on a post in the DCC RPG Rocks Facebook group. This looks like a pretty cool, and well thought out Patron. A Death Bat!
Camazotz, the bat god of death, fear, and blood was shackled in the House of Bats in the Underworld, and in the centuries since, evidence of his existence has almost entirely disappeared.
The statues and frescoes recovered through exploration depict Camazotz as a large man with a vampire bat’s head and bat wings. He wields a jagged dagger in one hand, and the severed head of a person in the other.
He survives on blood, thrives on fear, and demands his followers to supply him with both. These offerings slowly revive Camazotz’ strength, and he waits patiently for his chance to escape and take revenge on the world.
