Alastor stands out from many of the more chaotic residents of Hell for his well maintained amiable persona. He gives a first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. His behavior, mannerisms, and even his voice, are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, often using quaint anachronisms such as "the picture show" and refers to Charlie as a "charming demon belle". This playful dandyish exterior, however, obscures a much darker side to him - one with high levels of self-importance - and he will not hesitate to use physical violence when others don't act in line with his very particular values or expectations. He is noted to be narcissistic, with his love for himself being stated that no one else can measure up to it, and he does not see many people quite up to his level.[33] His smiling is a very self-enforced form of ego and a show of power and dominance; he looks down on anyone who lets their true emotions show, and even when faced with a rival in strength, if they let slip a frown, Alastor will see them as truly weak.[34][35] His smile is also to be more unpredictable and unnerving, and gives him a feeling of complete control over himself,[36] and uses his smile very seriously as a mask of his own emotions, even if he's alone.[37] Alastor is described as a man of duality.[38] He values good manners,[39] affability, and intelligence very highly in others, and will actively look down on those who do not meet his standards,[40] however, he will often play fast and loose with these arbitrary rules in regards to himself and his own conduct. He also has an odd sense of morality, which is described as "not normal",[41] and has been noted to be quite sadistic, even cannibalistic, devouring lesser demons or those that have incurred his anger. While Alastor is powerful, he is aware that there are other demons and entities that rival him in terms of power, such as other Overlords. For this reason, he is wary around such demons, as they could potentially harm him if he is not careful.
