Paimon is one of the most formidable of all demons because of his high rank in the demonic hierarchy. As a King of Hell, Paimon has command over a vast number of demons, which places him in a highly powerful and influential position.

His loud and thunderous voice can cause great unease or fear in those who hear it, making him all the more intimidating.  

In popular culture, notably in the horror movie “Hereditary,” Paimon’s portrayal highlights his desire for a human host to gain power in the physical world. This shows the extreme lengths he will go to achieve his goals.
