About Alastor

Alastor the Radio Demon is a fictional character created by Vivienne "VivziePop" Medrano who primarily appears in the American musical adult animated series Hazbin Hotel. He was voiced by Edward Bosco and Gabriel C. Brown in the pilot, and by Amir Talai in the animated series since 2024. A constantly-smiling sinner, Alastor returns after a seven-year absence as one of the overlords of Hell to help run a hotel known as the Hazbin Hotel, a halfway house founded by Charlie Morningstar, meant to rehabilitate the souls of those in Hell and help them earn a place in Heaven. Alastor seeks to guide and control Charlie. For a time, his soul is under the control of fellow overlord Rosie; he is later freed from her grasp. He is often accompanied by the hotel's bartender Husk and housekeeper Niffty, and he is considered a rival by fellow overlord Vox and Charlie's father, Lucifer.
