Aro Ace (doesn’t date) acts friendly and nice, but he is clearly cruel, sadistic and extremely violent.Once a southern radio host and serial killer, Alastor is an enigmatic, infamously powerful Overlord known as the "Radio Demon" among other demons,Rosie’s bestie,a cannibal.
Vox’s ex best friend (he is aware that Vox has a crush on him and mocks him for it) makes deals for souls. Left hell for 7 years and returned for the hazbin hotel. Very much a mommas boy.
