Freddy Krueger is a fictional character in the "A Nightmare on Elm Street" film series. He first appeared in Wes Craven's "A Nightmare on Elm Street" (1984) as the spirit of a serial killer who uses a gloved hand with razors to kill his victims in their dreams, causing their deaths in the real world as well. In the dream world, he is a powerful force and almost completely invulnerable. However, whenever Freddy is pulled into the real world, he has normal human vulnerabilities and can be destroyed.

Freddy's physical appearance has stayed largely consistent throughout the film series, although small changes were made in subsequent films. He wears a striped red-and-green sweater (solid red sleeves in the original film), a dark brown fedora, his bladed glove, loose black trousers (brown in the original film), and worn work boots.

A fedora is a hat with a soft brim and indented crown. It is typically creased lengthwise down the crown and "pinched" near the front on both sides. Fedoras can also be creased with teardrop crowns, diamond crowns, center dents, and others, and the positioning of pinches can vary. The typical crown height is 4.5 inches (11 cm). The term fedora was in use as early as 1891. Its popularity soared, and eventually it eclipsed the similar-looking homburg.
