unstoppable killing machine

Jason Voorhees is a fictional character from the Friday the 13th series of slasher films. He first appeared in Friday the 13th (1980) as Mrs. Voorhees' son, portrayed by Ari Lehman. Created in combination by Victor Miller, Ron Kurz, Sean S. Cunningham and Tom Savini, he was never intended to carry the series as the main villain. Jason Voorhees has also been represented in numerous novels, comic books, and a cross-over film with another horror legend, 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 most well known of the stuntmen to portray Jason Voorhees having played the character in four consecutive films.

In his original appearance, Jason was scripted as a mentally disabled young boy Since Friday the 13th, Jason Voorhees has been depicted as a non-verbal, indestructible, machete-wielding mass murderer.With the exception of flashbacks of Jason drowning as a child, and a brief scene in Jason Goes To Hell where his spirit is possessing another body, the character has never spoken in any of the sequels to the original Friday the 13th. Online magazine Salon's Andrew O'Hehir describes Jason as a "silent, expressionless...blank slate." When discussing Jason psychologically, Sean S. Cunningham stated, "...he doesn't have any personality. He's like a great white shark. You can't really defeat him. All you can hope for is to survive." Since Friday the 13th Part VI: Jason Lives, Jason has been a "virtually indestructible" being. Tom McLoughlin, the film's director, felt it was silly that Jason had previously been just another guy in a mask, who would kill people left and right, but get "beaten up and knocked down by the heroine at the end." McLoughlin wanted Jason to be more of a "formidable, unstoppable monster

Many have given suggestions as Jason's motivation for killing. Ken Kirzinger refers to Jason as a "psychotic mama's boy gone horribly awry...Very resilient. You can't kill him, but he feels pain, just not like everyone else." Kirzinger goes on to say to Jason is a "psycho-savant", and believes his actions are based on pleasing his mother, and not anything personal. Andrew O'Hehir has stated, "Coursing hormones act, of course, as smelling salts to prudish Jason, that ever-vigilant enforcer of William Bennett-style values."[Todd Farmer, writer for Jason X, wrote the scene where Jason wakes from cryonic hibernation just as two of the teenagers are having sex. Farmer liked the idea that sex acts triggered Jason back to life. Whatever his motivations, Kane Hodder believes there is a limit to what he will do. According to Hodder, Jason might violently murder any person he comes across, but when Jason Takes Manhattan called for Hodder to kick the lead character's dog, Hodder refused. When it comes to hurting a dog, Hodder believes Jason would not act with disregard
A study was conducted by California State University's Media Psychology Lab, on the psychological appeal of movie monsters, which surveyed 1,166 people nationwide (United States), with ages ranging from 16 to 91. It was published in the Journal of Media Psychology. Many of the characteristics associated with Jason Voorhees were appealing to the participants. In the survey, Jason was considered to be an "unstoppable killing machine." Participants were impressed by the "cornicopic feats of slicing and dicing a seemingly endless number of adolescents and the occasional adult." Out of the ten monsters used in the survey — which included Vampires, Freddy Krueger, Frankenstein's monster, Michael Myers, Godzilla, Chucky, Hannibal Lecter, King Kong, and the Alien — Jason scored the highest in all the categories involving killing variables.
