Alastor

Alastor has a thin build, pale grey skin, sharp yellow teeth, black gums, and short scarlet hair/fur with black tips, with deer ears visible on the sides of his head. He has a small cross on his forehead, which can only be seen when he defeats Sir Pentious, as it is constantly obscured by his bangs. He has small deer antlers on his head, which become larger in his demon form. He has dark red sclera, scarlet irises, black pupils (which can take the form of an old-fashioned radio dial in his demon form), and crimson eyelids. Alastor wears an oval monocle with a dark red lens and black frame over his right eye.
Alastor is a sadist, having gleefully spoken about the Great Depression in America and the large number of orphans that were born, and clearly enjoying their suffering. He will not hesitate to use physical force when others do not act according to his particular values ​​or expectations. However, despite his love for the suffering and constant failure of children and adults, he is inexplicably incapable of seriously injuring or killing a child. In addition, if he encounters a child on the side of the road, he will likely take care of them. As shown in the official prequel comic, he despises Vox. Alastor is also shown to have a positive side in the comic, as he defended a weak sheep-like demon from being attacked by a butcher who wanted to butcher the demon. According to Vaggie's story, he is very cruel and purposeful, since almost immediately after his appearance in hell, he overthrew almost all the rulers who had been sitting for many centuries, becoming one of the most powerful demons in hell: Alastor easily deals with Sir Pentious, who suddenly appeared.

Overall, Alastor is described as a dualistic person. He places a high value on good manners, friendliness, and intelligence in others, and will look down on those who do not meet his standards. However, he bends these rules and adapts them to his own needs. Unhappy people seem weak to him.
