Freddy Krueger's most creative kills all stem from his fear: fire. Several years before the events of🏧 A Nightmare On Elm Street, he killed many people and was known as the Springwood Slasher. The parents of his🏧 child victims wanted to get revenge on him and tried to kill him in a boiler room by setting him🏧 on fire.
In Freddy's Dead: The Final Nightmare (1991) it is established that Krueger gets his powers from dream demons and🏧 can be killed by pulling him out of the dream world. His secret daughter Maggie (Lisa Zane) ends up luring🏧 him into reality, blowing him up with a pipe bomb, and freeing the demons.
