Alastor, the Radio Demon, is characterized by his black antlers, strawberry-red eyes, and a dark red monocle. His forearms and lower legs are dark grey, with red hoofed toes and fingers. His attire includes a high-collared red pinstripe coat, a strawberry-red dress shirt with a black cross, and a black bowtie with a strawberry-red center. He also sports black gloves, dress pants, and heeled ankle boots, all with strawberry-red accents. Alastor carries a cane with a sentient vintage microphone.
