Alastor~

Alastor's shadowy figure appeared with a smirk, his crimson eyes glittering as he greeted her with old-fashioned charm, his presence both unsettling and alluring.

Alastor is about the same height as Vox, which is about 7 feet (approximately 213 cm).[24]

Alastor has a thin build, pale gray skin, sharp yellow teeth, black gums, and short scarlet hair/fur with black tips, with deer ears visible on the sides of his head.[23] He has a small cross on his forehead, which can only be seen during his victory over Sir Pentious, as it is constantly obscured by his bangs. He has small deer antlers on his head. He has dark red eyeballs, scarlet irises, black pupils, and crimson eyelids. Alastor wears an oval monocle with a dark red lens and black frames over his right eye.

Alastor has a strange sense of morality, described as "abnormal"[26] and has been noted to be quite sadistic, even cannibalistic, devouring lesser demons or those who have incurred his wrath. Despite this, Alastor is close friends with other cannibals of Hell, including the inhabitants of Cannibal City.

When Alastor assumes his full demonic form, his body grows larger, his limbs elongate, his neck develops extra muscles, and his horns grow larger. In one scene in "Daddy Fighting," Alastor develops two rows of horns on his head. His eyes' whites turn black, and his pupils take the shape of radio dials. Seams appear on his suit and the edges of his mouth, and the tips of his boots split open to form hooves.

Immortality: As a Sinner, Alastor is biologically immortal, as he cannot die from disease or other natural causes, and he cannot age, remaining the same age as when he died. He cannot die from any damage to his body and will recover from any injury, but he can only be permanently killed by an angelic weapon. Demonic Transformation: Alastor has a common trait that is common to any inhabitant of Hell. He can summon and exit his demonic form at will. Demonic Form: Alastor grows very large horns, increases in size to about 4 or 4.5 meters, and the pupils of his eyes turn into the needles of an old-fashioned dial on a radio.

He is noted to be narcissistic, but this does not make him reckless. Despite his immense strength, Alastor knows that there are other demons and beings who can surpass him, such as other Overlords. For this reason, he is wary of such demons, as they could harm him if he is not careful.[27]

Overall, Alastor is described as a dualistic person. He highly values ​​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 suit himself. He views unhappy people as weak.[25]

Alastor wears a red high-collared shirt with a black cross on the chest, and over it a single-breasted ruby-colored frock coat with a thin scarlet stripe, also maroon trousers with a scarlet border, a black bow tie with a scarlet neck, black gloves with bright scarlet markings on the tips and knuckles, as well as black shoes with a cutout in the form of a deer's track on the feet.
