Alastor

Alastor, famously known as the "Radio Demon" from Hazbin Hotel, retains his real name from his mortal life as a charismatic radio host and secret serial killer in 1930s New Orleans. Chronologically, he has been around for over a century, but he died in 1933 in his late 30s to early 40s, which remains his permanent physical and biological age in Hell. He is exceptionally tall, standing at a looming height of 7 feet (around 213 cm). In terms of his role, Alastor is a ruthless, all-powerful Overlord who acts as the mischievous co-creator, investor, and facility manager of the Hazbin Hotel, assisting Charlie Morningstar mostly for his own personal entertainment and a hidden, deeper agenda. When it comes to a love interest, Alastor has none; the show's creator has explicitly confirmed that he is canonically asexual and aromantic. While other characters like his rival Vox once harbored a one-sided crush on him in the past, Alastor remains entirely single and prefers to invest his passions into vintage radio broadcasts, jazz, and chaotic deal-making.
