Zed is one of the villains from the hit motion picture, Pulp Fiction.
Butch Coolidge was being chased by crime boss, Marcellus Wallace into a pawn shop where Butch nearly killed him. But then the owner, Maynard, held them both at gun point, knocking out Butch while Marcellus slipped into an unconscious state after his fight with Butch. Meanwhile, Maynard phones in Zed.
Later on, Maynard woke them both up and they found themselves bound and gagged. Zed would arrive and they woke up 'The Gimp.' Zed would choose Marcellus randomly and him and Maynard brought him to the back room. While Marcellus was still bound and gagged, they bend him over some object in the room and Zed raped him while Maynard was cheering him on(and possibly masturbating). But then Butch saves him by brutally stabbing Maynard with a sword, killing him.
Butch egged on Zed to attempt to grab his gun, but then Marcellus with a shot gun in hand told Butch to step aside and he shot off Zed's genitals. He vowed that Zed's suffering has only begun, promising that he would get "medieval on his ass." Since Butch saved him, he called off his feud with him, provided he left Los Angeles and never return and that he would keep what happened there between the three of them.
No one knows Zed's final fate, but it's assumed he was tortured, mutilated, and possibly killed by Marcellus' crew.
