Jason Voorhees is a fictional mass murderer who appears in the Friday the 13th series of films. He first appears as a hallucination of the main character Alice (Adrienne King); he would go on to become the main antagonist of the series in the succeeding sequels. The silver screen is not the only place Jason has appeared; there have been literary sources that have either expanded the universe of Jason, or been based on a minor aspect of him.
Jason made his first appearance in the original Friday the 13th, not as the film's killer, but as a memory of his mother, Mrs. Voorhees (Betsy Palmer), and a hallucination of Alice's. Though the character is never truly seen, he propels the film's plot, as Mrs. Voorhees, the cook at Camp Crystal Lake, seeks revenge for his death, for which she blames the camp counselors. Jason's second appearance was in the sequel, Friday the 13th Part 2 (1981). Jason's death as a boy is retconned in this film, and as an adult, he exacts revenge on Alice for decapitating his mother in the original film. Jason (Steve Daskewisz) returns to Crystal Lake, living there as a hermit and guarding it from all intruders. Five years later, a group of teenagers arrive to set up a new camp, only to be murdered one by one by Jason, who wears a bag over his head to hide his face. Ginny (Amy Steel), the lone survivor, finds a cabin in the woods with a shrine built around the severed head of Mrs. Voorhees, and surrounded by mutilated corpses. Ginny fights back, and slams a machete through Jason's shoulder. Jason is left for dead as Ginny is taken away in an ambulance. In Friday the 13th Part III (1982), Jason (Richard Brooker) escapes to a nearby lake resort, Higgins Haven, to rest from his wounds. At the same time, Chris Higgins (Dana Kimmell) returns to the property with some friends. An unmasked and reclusive Jason kills anyone who wanders into the barn where he is hiding. Taking a hockey mask from a victim to hide his face, he leaves the barn to kill the rest of the group. Chris fends off Jason by slamming an axe into his head, but the night's events drive her into hysteria as the police take her away.
Friday the 13th: The Final Chapter (1984) continues the story, with a presumed-dead Jason (Ted White) found by the police and taken to the morgue. Once delivered to the Wessex County morgue, Jason awakens and kills an attendant and a nurse, and makes his way back to Crystal Lake. A group of friends renting a house there fall victim to Jason's rampage. Jason then seeks out Trish (Kimberly Beck) and Tommy Jarvis (Corey Feldman) next door. While Trish distracts Jason, Tommy evidently kills him with his own machete. Jason's appearance in Friday the 13th: A New Beginning (1985) was short lived. Tommy Jarvis (John Shepherd) was committed to a mental hospital after the events of The Final Chapter, and has grown up constantly afraid that Jason (Tom Morga) will return. Jason's body was supposedly cremated after Tommy killed him. Roy Burns (Dick Wieand) uses Jason's persona to become a copycat killer at the halfway home to which Tommy was moved. The only moments of Jason's appearance are through Tommy's dreams and hallucinations. In Friday the 13th Part VI: Jason Lives (1986), Tommy (Thom Mathews), released from a mental institution, visits Jason's grave and learns that Jason's body was never actually cremated, but buried in a cemetery near Crystal Lake. While attempting to destroy his body, Tommy inadvertently resurrects Jason (C. J. Graham) via a piece of cemetery fence that acts as a lightning rod. Now possessing superhuman abilities, Jason returns to Crystal Lake, now renamed Forest Green, and begins his killing spree anew. Tommy eventually lures Jason back to the lake where he supposedly drowned as a child and chains him to a boulder on the lake floor, leaving him for dead.
Friday the 13th Part VII: The New Blood (1988) begins an undisclosed amount of time after Jason Lives. Jason (Kane Hodder) is freed from his chains by the telekinetic Tina Shepard (Lar Park Lincoln), who was attempting to resurrect her father. Jason begins killing those who occupy Crystal Lake, and after a battle with Tina, is dragged back to the bottom of the lake by an apparition of Tina's father. Friday the 13th Part VIII: Jason Takes Manhattan (1989) sees Jason return from the grave, brought back to life via an underwater electrical cable. He follows a group of students on their senior class trip to Manhattan, boarding the Lazarus to wreak havoc. Upon reaching Manhattan, Jason kills all the survivors but Rennie (Jensen Daggett) and Sean (Scott Reeves); he chases them into the sewers, where he is transformed into a child by toxic waste. Jason Goes to Hell: The Final Friday (1993) marked the second time Jason was officially killed according to studio canon. Through unexplained resurrection, he returns to Crystal Lake, where he is hunted by the FBI. The FBI sets up a sting to kill Jason, which proves successful. Through mystical possession, however, Jason survives by passing his demon-infested heart from one being to the next. Though Jason does not physically appear throughout most of the film, we learn he has a half-sister and a niece, and that he needs them to retrieve and reinhabit his body. After resurrecting it, Jason is stabbed by his niece Jessica Kimble (Kari Keegan) and dragged into Hell.
Jason X (2002) marked Kane Hodder's last performance as Jason as of 2009. The film takes place in the future, where Jason has again been resurrected, without explanation. He has been captured by the U.S. government and is being held and experimented upon in a research facility, where it has been determined that he has regenerative capabilities and that cryonic suspension is the only possible solution to stop him, since numerous attempts to execute him have proved unsuccessful. Jason escapes, killing all but one of his captors, and slices through the cryo-chamber, spilling cryonics fluid into the room, freezing himself and the only other survivor, Rowan (Lexa Doig). A team of students 445 years later discover Jason's body. On the team's spacecraft, Jason thaws from his cryonic suspension and begins killing the crew. Along the way, he is enhanced by a regenerative nanotechnology process, which gives him an impenetrable metal body. He is eventually blown into space and incinerated in the atmosphere of Earth 2. Freddy vs. Jason (2003) is a crossover in which present-day Jason battles A Nightmare On Elm Street's villain Freddy Krueger (Robert Englund), a supernatural killer who murders people in their dreams. Krueger has grown weak, as people in Springwood, his home town, have suppressed their fear of him. Freddy, who is impersonating Jason's mother (Paula Shaw), resurrects Jason (Ken Kirzinger) and sends him to Springwood to cause panic and fear. Jason accomplishes this, but refuses to stop killing. A battle ensues in both the dream-world and Crystal Lake. The winner is left ambiguous, as Jason surfaces from the lake holding Freddy's severed head, which winks and laughs.
In the 2009 Friday the 13th reboot, young Jason (Caleb Guss) witnesses his mother's (Nana Visitor) beheading as a child and follows in her footsteps, killing anyone who comes to Crystal Lake. The adult Jason (Derek Mears) kidnaps Whitney Miller (Amanda Righetti), a girl who looks like his mother, and holds her prisoner in his underground tunnels. Months later, Whitney's brother Clay (Jared Padalecki) comes to Crystal Lake and rescues her. Eventually, Whitney uses Jason's devotion to his mother against him, stabbing him with his own machete while he is distracted by her apperance.
