Eddie Quist was a serial killer and werewolf who stalked the streets of Los Angeles in the early 1980s. After gaining some moderate level of notoriety after a series of killings, he developed an attraction to KDHD news anchor Karen White. Eddie contacted Karen and arranged to meet with her. Karen informed her supervisors as well as local law enforcement and they used her as part of a sting operation to finally get their hands on the mysterious "Eddie the Mangler".

Karen met Eddie inside a private movie booth and Eddie forced her to watch a film of a woman being raped. He wouldn't let Karen see his face, but spoke to her in low, even tones. After extolling his personal philosophy to her, he entreated Karen to turn around. Upon doing so, she saw Eddie undergo the beginning of a transformation into a werewolf. At this time, police officers entered the establishment and upon hearing Karen scream in terror emptied their firearms into the booth, seemingly killing Eddie in the process. Karen was so traumatized by the incident that she blanked the entire experience from her memory. Eddie's body was then taken to the morgue awaiting identification.

Eddie decided to finish what he had started in Los Angeles. Telling Karen that he wanted to give her "a piece of my mind", Eddie then dug the bullet out of his skull, and began a gradual, protracted transformation into his werewolf form. Karen watched in horror, but before Eddie could complete the transformation, she picked up a jar of sulfuric acid from Waggner's desk and splashed it on Eddie. Eddie reeled in pain and Karen ran for her life.
