tbf he doesnt exactly have to try with verbal threats when just showing a glimpse of his power level causes hallucinations of tv static

Honestly out of all the threats made in the show, his was the most unsettling. Every other demon has either gotten violent off the bat, or made numerous threats with swears and crudeness.

Radio Demon casually just states the truth as he begins to show us a glimpse of his reality bending powers. He's the only one I actually feel worried about compared to everyone else.
