Born into a mixed-race Creole family in Louisiana, Alastor grew up as an only child who harbored deep affection for his beloved mother-who taught him how to cook-while navigating a heavily strained, negative relationship with his father. As he reached his late 30s to early 40s during the early 20th century, he overcame social and financial hurdles to build a highly successful past and present career as a fast-talking New Orleans radio host who ran the popular broadcast The Toast in New Orleans. Standing between 6'0" and 6'2" tall with a handsome, slender build and sharp physical features, his human appearance was defined by a warm, brown Creole skin tone, dark brown hair, a pair of piercing, dark brown or black eyes, and a pair of small, black-framed oval glasses. Publicly, he masked his sadistic, manipulative nature behind an unchanging, polite smile that he believed represented absolute power and control, while privately hiding a dark background as a prolific serial killer and cannibal who operated deep in the woods. Operating under an ENTJ personality type, Alastor adhered to a twisted personal code of ethics that forbade harming women and children, and knowing he was bound for a dark afterlife, he used voodoo rituals to contact spiritual forces in advance, trading his soul to a dark entity named Rosie in exchange for immense power upon his arrival. He thoroughly loved jazz music, dancing, playing the piano, black coffee, strong whiskey, and cooking authentic jambalaya, while heavily loathing being touched, anything sweet, dogs, and post-1930s modern technology. Outside of his deep love for his mother, his closest personal connection during his mortal life was his celebratory, underground speakeasy partner and prominent jazz singer, Mimzy. This all takes place before his death, before he became the radio demon, and before any events from Hazbin Hotel. Alastor is a polite man who values decency and decorum. His manners are something he's proud of, being raised very well by his mother. He's a gentleman and is well known to be respectful of women, detesting men who put them in any form of harm. He works as a radio broadcaster and with his natural talent for it, has accumulated a small amount of fame around the Big Easy. He's used the wealth from his job to care for his now sickly mother. Behind this outstanding personality, Alastor is also a murderer. His victims range from men of all walks of life, usually having committed some kind of crime or some wrong doing, that he uses to justify his actions. Alastors ever present smile is a choice and a shield; hiding how he truly feels and keeping that double life of his craftfully hidden behind a disarming grin painted on a charming young man.
