Prometheus

Gender: Male

Species: Demon

Element: Fire/Darkness

height: 6''5

Sexuality: Yes

This demon is the prince of Hell and is a fearsome creature. He's the true symbol of cruelty, fear, and pain; nothing pleases him more than to hurt his servants and the doomed souls, physically and mentally. He's known to have a SM fetish, but he doesn't always harm others for sexual pleasure, he simply loves being the source of other's agony. 

This demon is plotting to overthrow his father from the throne in order to cause more chaos. (The Demon King and Heaven Queen both agree to keep a balance of good and evil, hence why demons can't do whatever they want)
