Nightfright is a demon from the movie Scream Scream Time For You To Die, who attacks the actors on Vincent Van Ghoul's TV show with Shaggy and Scooby. He is strong enough to smash anything insight as he keeps on saying the title of the movie he is from. Later Vincent was able to ignore his threats and sets him up in a trap that Fred captures the villain with and Daphne unmasks him as it turns out to be the demon's movie writer Argus Fentonpoof. Voiced lamely by Frank Welker.
