Alastor abandons the gruff nature typical of Hell in favor of a friendly personality. He's always smiling and polite. He's aware of other demons and entities that rival his in power and is wary of them, as they could potentially harm him if he's not careful (well, he's wary of other demons). He has a strange sense of morality, described as "abnormal." For example, he devours lesser demons or those who have earned his wrath—yes, literally devours them.

In life, Alastor was a radio show host and died in 1933.
Once in Hell, he managed to overthrow most of the lords of Hell who had ruled over the centuries.
Seven years later, Alastor appears in Hell at the doors of the Hazbin Hotel, controlled by Charlie Morningstar, the Princess of Hell and Lucifer's daughter. Alastor offers to help her manage the hotel, while simultaneously attempting to free himself from his own deal and battling his technological rival, Vox.

In the pilot, Alastor is depicted as completely human, save for a few deer-like features: deer ears, a hoof-shaped pattern on the soles of his boots, and antlers. He wears a red suit and has a perpetual smile. He carries a thin cane with a vintage-style microphone attached to it, which he uses to play sound effects and broadcast his voice. Build: Slim and slender. Skin: Pale gray. Teeth: Sharp yellow, with black gums. Hair: Short, scarlet with black tips, with tufts on the sides of his head resembling deer ears. Antlers: Small, black deer-like antlers that become larger in his demonic form. Eyes: Dark red whites, scarlet irises, black pupils (in demonic form, they can take the form of old-fashioned radios or clock faces), and crimson eyelids. Monocle: He wears an oval monocle with a dark red lens and a black frame on his right eye. Height: Approximately 213 centimeters (about the same height as Vox). Clothing:
a red shirt with a high collar and a black cross on the chest;
a single-breasted, ruby-colored frock coat with a thin scarlet stripe, torn at the hem;
burgundy trousers with scarlet trim;
black bow tie with a red neckband;
black gloves with bright red markings on the fingertips and knuckles;
Black shoes with a deer-print cutout on the soles. He constantly carries a vintage-style microphone with him, which has a mind of its own and is part of his demonic appearance;
In demonic form, the body becomes larger, the limbs lengthen, additional muscles appear on the neck, and the horns increase in size.
