Literature[edit]
Jason first appeared outside of film in the 1982 novelization of Friday the 13th Part 3 by Michael Avallone.[19] Avallone chose to use an alternate ending, which was filmed for Part 3 but never used, as the ending for his 1982 adaptation. In the alternate film ending, Chris, who is in the canoe, hears Rick's voice and immediately rushes back to the house. When she opens the door, Jason is standing there with a machete, and he decapitates her.[20] Jason next appears in print in the 1986 novelization of Jason Lives by Simon Hawke,[21] who also adapted the first three films in 1987 and 1988.[22][23][24] Jason Lives specifically introduced Elias Voorhees, Jason's father, a character that was slated to appear in the film but was cut by the studio. In the novel, instead of being cremated, Elias has Jason buried after his death.[25]

Jason made his comic book debut in the 1993 adaptation of Jason Goes to Hell, written by Andy Mangels. The three-issue series was a condensed version of the film, with a few added scenes that were never shot.[26] Jason made his first appearance outside of the direct adaptations in ♥♥♥♥♥'s Six No. 4, published in 1993, which is a continuation of the events of Jason Goes to Hell.[27] In 1995, Nancy A. Collins wrote a three-issue, non-canonical miniseries involving a crossover between Jason and Leatherface. The story involves Jason stowing away aboard a train, after being released from Crystal Lake when the area is drained due to heavy toxic waste dumping. Jason meets Leatherface, who adopts him into his family after the two become friends. Eventually they turn on each other.[28] In 1994 four young adult novels were released under the title of Friday the 13th. They did not feature Jason explicitly, but revolve around people becoming possessed by Jason when they put on his mask.[29][30][31][32]

In 2003 and 2005, Black Flame published novelizations of Freddy vs. Jason and Jason X respectively.[33][34] In 2005 they began publishing a new series of novels; one set was published under the Jason X title, while the second set utilized the Friday the 13th title. The Jason X series consisted of four sequels to the novelization of the film. Jason X: The Experiment was the first published. In this novel, Jason is being used by the government, who are trying to use his indestructibility to create their own army of "super soldiers".[35] Planet of the Beast follows the efforts of Dr. Bardox and his crew as they try to clone the body of a comatose Jason, and shows their efforts to stay alive when Jason wakes from his coma.[36] Death Moon revolves around Jason crash-landing at Moon Camp Americana.[37] Jason is discovered below a prison site and unknowingly awakened in To The Third Power. Jason has a son in this book, conceived through a form of artificial insemination.[38]

On May 13, 2005, Avatar Press began releasing new Friday the 13th comics. The first, titled Friday the 13th, was written by Brian Pulido and illustrated by Mike Wolfer and Greg Waller. The story takes place after the events of Freddy vs. Jason, where siblings Miles and Laura Upland have inherited Camp Crystal Lake. Knowing that Jason caused the recent destruction, Laura, unknown to her brother, sets out to kill Jason using a paramilitary group, so that she and her brother can sell the property.[39] A three-issue miniseries titled Friday the 13th: Bloodbath was released in September 2005. Written by Brian Pulido and illustrated by Mike Wolfer and Andrew Dalhouse, the story involves a group of teenagers who come from Camp Tomorrow, a camp that sits on Crystal Lake, for work and a "party-filled weekend". The teenagers discover they share common family backgrounds, and soon awaken Jason, who hunts them.[40] Brian Pulido returned for a third time in October 2005 to write Jason X. Picking up after the events of the Jason X film, Über-Jason is now on Earth II where a biological engineer, Kristen, attempts to subdue Jason, in hopes that she can use his regenerative tissue to save her own life and the lives of those she loves.[41] In February 2006 Avatar published Friday the 13th: Jason vs. Jason X. Written and illustrated by Mike Wolfer, the story takes place after the events of the film Jason X. A salvage team discovers the spaceship Grendel and awakens a regenerated Jason Voorhees. The "original" Jason and Über-Jason are drawn to each other, resulting in a battle to the death.[42] In June 2006 a one-shot comic entitled Friday the 13th: Fearbook was released, written by Mike Wolfer with art by Sebastian Fiumara. The comic has Jason being captured and experimented upon by the Trent Organization; Jason escapes and seeks out Violet, the survivor of Friday the 13th: Bloodbath, who is being contained by the Trent Organization in their Crystal Lake headquarters.[43]

The Friday the 13th novella storyline was not connected to the Jason X series, and did not continue the stories set forth by the films, but furthered the character of Jason in its own way. Friday the 13th: Church of the Divine Psychopath has Jason resurrected by a religious cult.[44] Jason is stuck in Hell, when recently executed serial killer Wayne Sanchez persuades Jason to help him return to Earth in Friday the 13th: Hell Lake.[45] In Hate-Kill-Repeat, two religious serial killers attempt to find Jason at Crystal Lake, believing that the three of them share the same contempt for those that break the moral code.[46] In The Jason Strain, Jason is on an island with a group of convicts placed there by television executives running a reality game show.[47] The character of Pamela Voorhees returns from the grave in Carnival of Maniacs. Pamela is in search of Jason, who is now part of a traveling sideshow and about to be auctioned off to the highest bidder.[48]

In December 2006 DC Comics imprint Wildstorm began publishing new comic books about Jason Voorhees under the Friday the 13th moniker. The first set was a six-issue miniseries involving Jason's return to Camp Crystal Lake, which is being renovated by a group of teenagers in preparation for its reopening as a tourist attraction. The series depicts various paranormal phenomena occurring at Crystal Lake. Jason's actions in this storyline are driven by the vengeful spirits of a Native American tribe wiped out on the lake by fur traders sometime in the 19th century.[49][50] On July 11 and August 15, 2007, Wildstorm published a two-part special entitled Friday the 13th: Pamela's Tale. The two-issue comic book covers Pamela Voorhees' journey to Camp Crystal Lake and the story of her pregnancy with Jason as she recounts it to hitchhiker Annie, a camp counselor who was killed in the original film.[51] Wildstorm released another two-part special, entitled Friday the 13th: How I Spent My Summer Vacation, that was released on September 12 and October 10, 2007. The comic book provides new insight into the psychology of Jason Voorhees as he befriends a boy born with a skull deformity.[52] Wildstorm has planned a six-issue series called Freddy vs. Jason vs. Ash, starring the two killers and Ash from the Evil Dead series. In this story, Freddy uses the Necronomicon, which is in the Voorhees' basement, to escape from Jason's subconscious and "gain powers unlike anything he's had before". Freddy attempts to use Jason to retrieve the book, stating it will make him a real boy. Ash, who is working at the local S-Mart in Crystal Lake, learns of the book's existence and sets out to destroy it.[53] Wildstorm released another two-issue miniseries on January 9 and February 13, 2008, titled Friday the 13th: Bad Land, written and illustrated by Ron Marz and Mike Huddleston respectively. The miniseries features Jason stalking a trio of teenaged hikers taking shelter from a blizzard in Camp Crystal Lake.[54]

Appearances
Jason Voorhees first appears during a nightmare of the main character Alice (Adrienne King) in the original Friday the 13th film; he becomes the main antagonist of the series in its sequels. As well as the films, there have been books and comics that have either expanded the universe of Jason, or been based on a minor aspect of him.

Films
Jason made his first cinematic appearance in the original Friday the 13th on May 9, 1980. In this film, 10-year-old Jason is portrayed in the memories of his mother, Mrs. Voorhees (Betsy Palmer), and as a hallucination of the film's protagonist, Alice. Though the character makes no contemporary appearance onscreen, he propels the film's plot—Mrs. Voorhees, the cook at Camp Crystal Lake, seeks revenge for his death, which she blames on the camp counselors.[7] Jason's second appearance was in the sequel, Friday the 13th Part 2 (1981). Revealed to be alive, an adult Jason exacts revenge on Alice for decapitating his mother in the original film. Jason (Warrington Gillette), 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.[8] 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.[9]

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. Jason awakens at the morgue 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.[10] Friday the 13th: A New Beginning follows Tommy Jarvis (John Shepherd), who 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 (♥♥♥♥ Wieand) uses Jason's persona to become a copycat killer at the halfway home to which Tommy was moved. Jason appears in the film only through Tommy's dreams and hallucinations.[11] 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.[12]

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.[13] 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.[14] Jason Goes to Hell: The Final Friday (1993) marked the second time Jason was officially killed according to studio canon. Through an 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, it is learned 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.[15]

Jason X (2002) marked Kane Hodder's last performance as Jason. The film starts off in 2010; Jason has returned after an unexplained resurrection. Captured by the U.S. government in 2008, Jason is being 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. Finally, he is ejected into space and falls to the planet Earth 2, burning in the atmosphere.[16]

Set before the events of Jason X, Freddy vs. Jason (2003) is a crossover film in which 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 his home town of Springwood have suppressed their fear of him. Freddy, who is impersonating Jason's mother (Paula Shaw), resurrects Jason (Ken Kirzinger) from Hell 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 identity of the winner is left ambiguous, as Jason surfaces from the lake holding Freddy's severed head, which winks and laughs.[17]

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 when she appears.[18]
