Jason Voorhees is a fictional character from the Friday the 13th series of slasher film. He first appeared in Friday the 13th (1980), as the son of camp cook-turned-murderer, Mrs. Voorhees, in which he was portrayed by Ari Lehman. Created by Victor Miller, with contributions by Ron Kurz, Sean S. Cunningham, and Tom Savini, Jason was not originally intended to carry the series as the main villain. The character has subsequently been represented in various other media, including novels, comic books, and a cross-over film with another iconic horror film character, Freddy Krueger.
The character has primarily been an antagonist in the films, whether by stalking and killing the characters, or acting as a psychological threat to the lead character, as is the case in Friday the 13th: A New Beginning. Since Lehman's portrayal, the character has been represented by numerous actors and stuntmen, sometimes by more than one at a time; this has caused some controversy as to who should receive credit for the portrayal. Kane Hodder is the best known of the stuntmen to portray Jason Voorhees, having played the character in four consecutive films.
The character's physical appearance has gone through many transformations, with various special makeup effects artists making their mark on the character's design, including makeup artist Stan Winston. Tom Savini's initial design has been the basis for many of the later incarnations. The trademark hockey mask did not appear until Friday the 13th Part III. Since Friday the 13th Part VI: Jason Lives, filmmakers have given Jason superhuman strength, regenerative powers, and near invulnerability. He has been seen as a sympathetic character, whose motivation for killing has been cited as driven by the immoral actions of his victims. Jason Voorhees has been featured in various humor magazine, referenced in feature films, parodied in television shows, and been the inspiration for a horror punk band. Several toy lines have been released based on various versions of the character from the Friday the 13th films. Jason Voorhees's hockey mask is a widely recognized image in popular culture.
Jason Voorhees first appears as a hallucination of the main character Alice (Adrienne King) in the original Friday the 13th film; he becomes the main antagonist of the series in the succeeding 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.
