The Summer of Freddy vs Jason won't work without Freddy, obviously.. so let's jump right into A Nightmare on Elm Street and introduce the guy!

He's a snarky serial killer who torments children in their dreams, toying with them while performing vertical unanesthetized street surgery. Of course like Jason, it took a couple movies to really hammer him down...
