"Don't go to sleep!" Defy sleep or risk a visit from Freddy Kreuger himself, star of the 1984 horror film "A Nightmare on Elm Street." A severely burned serial killer, Freddy uses a gloved arm laced with razor blades to kill his victims in their dreams, causing their deaths in the waking world as well. Appearing in films, television series like "Freddy's Nightmares," video games, and comics, Freddy is known for his disfigured face, red-and-green striped sweater, brown fedora, and that brown leather glove with metal claws, made for murder. He's a pop culture icon who represents true horror.
