Eddie (last name unrevealed) was an inmate at Pinehurst Sanitarium for Juvenile Delinquents. It is unknown what he was imprisoned for. Eddie took delight in playing pranks and sneaking out to have sex with his girlfriend, which put him at odds with the locals. He also ended up receiving a brutal beating from Tommy Jarvis after stealing one of Tommy's monster masks.
Eddie was slain by Roy Burns, the Jason impostor who was targeting inmates at Pinehurst after one had murdered his son. Roy killed him by having his belt tied around his head and twisted until it caved in his eyeballs.
In Freddy Vs Jason Vs Ash, Freddy uses the Necronomicon to summon up "All Voorhees victims past and present" as Deadites to dispose of Jason. Eddie is among them and seemingly possesses the most strength and gets the most panel time.
This appearance is a continuity disaster, as Eddie was killed by neither Jason Voorhees or his mother Pamela. It is possible that the "Jason Victim" Deadites were actually demons and not the people they appeared to be. Another possibility is that Burns was possessed by Jason.
