Freddy Krueger is the antagonist of the A Nightmare on Elm Street horror film franchise. Created by Wes Craven, he made his debut in Craven's A Nightmare on Elm Street (1984) as the malevolent spirit of a child killer who had been burned to death by his victims' parents after evading prison. Krueger goes on to murder his victims in their dreams, causing their deaths in the real world as well. In the dream world, he is a powerful force and seemingly invulnerable. However, whenever Freddy is pulled back into the real world, he has normal human vulnerabilities and can be destroyed. He is commonly identified by his burned, disfigured face, dirty red-and-green-striped sweater and brown fedora, and trademark metal-clawed, brown leather, right hand glove. This glove was the product of Krueger's own imagination, having welded the blades himself before using it to murder many of his victims, both in the real and dream worlds. Over the course of the film series, Freddy has battled several reoccurring survivors including Nancy Thompson and Alice Johnson. The character was consistently portrayed by Robert Englund in the original film series as well as in the television spin-off Freddy's Nightmares.
