This was a more interesting list than I anticipated. Thank you, Johnny, for your time and interesting writeups.
My original list was only 5 long, but my wife, who is far more into vampires than I, would not stand for it. There were several on the countdown that I should have thought of, though.
(BTW, I voted for Count Cocofang, was that lumped in with Chocula?)
