Detroit had a three that I remember.
Saturday afternoons brought us Sir Graves Ghastly. Pretty cheesy and tame. Passable at the time for younger children, I suppose.
Saturday nights had The Ghoul. More edgy and subversive, and more appealing to me. It seemed like he might have split his time between Detroit and Cleveland, as he was on and off the air in Detroit from time to time.
Also on, but more of a limited, special occasion basis was Count Scary. Kind of a middle ground option, not as manic and cool as the Ghoul, but not quite as campy as ol' Sir Graves.
