Jason Voorhees

Jason Voorhees is the main character from the Friday the 13th series. He is the main antagonist in films Friday the 13th Part 2 through the 2009 film of the same name.

Debut
Jason Voorhees first appears during a nightmare of the main character Alice Hardy (Adrienne King) in the original Friday the 13th film. Jason made his first cinematic appearance in the original Friday the 13th on May 9, 1980. In this film, Jason (Ari Lehman) is portrayed in the memories of his mother, Mrs. Voorhees (Betsy Palmer), and as a nightmare of the film's protagonist, Alice (Adrienne King). Although not a central character in the original movie, he is still the catalyst of the film's plot—Mrs. Voorhees, the main antagonist, seeks revenge for her son's drowning, which she blames on the irresponsible camp counselors.

An Early Encounter
After killing Alice 3 years later, and his mother's death a few months before Alice's death, he went after a teenage girl, pursuing her with a knife. Chris Higgins, the teenager, fought back but Jason knocked her out.

Packanack Lodge Massacre
Jason heads to a camp where teenage counselors are reopening it. Determined to destroy the trespassers, he began to watch the group closely and stalk them to their deaths. He kills Deputy Winslow and annoying doomsayer Ralph. After killing those two, he attacks the lodge ,where the other counselors are, while lovers Ginny Field and Paul Holt are out a bar, slashing Scott's throat, killing Terry off-screen, hitting a machete in Mark's face, impaling Jeff Dunsberry and Sandra Dier, and lastly stabbing Vickie Perry in the stomach. After the would-be counselors are dead, Ginny and Paul and Jason appears, knocking Paul out and chasing Ginny. Ginny arrives in a shrine where Pamela Voorhees' head lies. She grabs a machete and slams it into Jason's shoulder after psychologically acting like Mrs Voorhees. Jason, unmasked, breaks a window and grabs Ginny.

Higgins Haven Massacre
A day after the events at the Packanack Lodge, Jason steals some clothes and kills a middle-aged couple. A group of kids in their early 20's are driving along the road when they run into a man named Abel, who warns them to turn back around. Ignoring his warning, the kids head to Higgins Haven, where Chris Higgins lived when she was a teen. Jason also heads there and hides in a barn. Sooner, blind daters Shelly and Vera head to a nearby store, meeting a biker group. The bikers, Loco, Ali, and Fox, head to the barn where they are attacked by Jason, resulting in Fox and Loco's deaths and Ali is beaten unconscious. At night, while Chris and her boyfriend Rick are out walking, Jason ambushes the rest of the group, slashing Shelly's throat, stabbing Debbie, impaling Chilli with a fire poker, shooting a harpoon in Vera's eye, electrocuting Chuck, which makes the power go out, resulting in Chilli's death, and Jason cuts Andy in half while Andy's walking on his hands. Chris and Rick make it back to the cabin, discovering that it's quiet. Rick heads outside and gets his head crushed. Jason then chases after a scared Chris. After stabbing Jason in the leg and pushing a bookcase on him, Chris runs to the barn and arms herself with a shovel. Jason makes it there and is knocked out, giving Chris enough time to tie a noose around his neck. Jason wakes back up, unmasks himself, revealing that he was the man who attacked her in 1982. He releases himself from the noose and slowly walks toward Chris until Ali wakes up. Jason kills Ali, giving Chris enough time to strike an ax into Jason's head. Jason walks toward her, grabbing for her. When the sun rises, Chris gets in a canoe and is attacked by Pamela Voorhees ,shortly after an unmasked Jason runs toward her. The police shortly rescue her and put her in their car

The Murders Next Door
After the events at Higgins Haven, Jason is taken to the hospital where he kills doctor Axel Burns and nurse Robbie Morgan. A day later, a group of teens are driving down the road to a house in Crystal Lake. The group consists of Paul, his girlfriend Sam, virgin Sara, her boyfriend Doug, awkward Jimmy, and jokester Ted. The teenagers come across a hitchhiker, who is killed by Jason, and Pamela Voorhees's tombstone. Afterwards, the teens meet Trish and Tommy Jarvis, their dog Gordon. The next day, they also meet twins Terri and Tina, then they all go skinny dipping, which the Jarvis kids happen upon. The teens invite Trish to their party taking place that night. The Jarvis family's car breaks and they get help from Rob Dier, who they take to their house to meet their mother. The teens start to party and Tina and Paul flirt with each other, angering and upsetting Sam, who leaves to go out for a swim. Jason impales Sam, similar to what he did to Debbie in Part III. After killing Sam, Paul is shot in the groin with a harpoon gun by Jason. Terri leaves the party but before getting on her bike, she is impaled with a spear. Mrs Jarvis makes it home and discovers the kids aren't there and that the power is out. She looks for the kids and Gordon but is killed by Jason offscreen. Trish and Tommy arrive, realizing that their mother is gone. Trish leaves Tommy to turn the power back on and she leaves to find Mrs Jarvis. She runs into Rob Dier, who explains that he is Sandra Dier's brother and came to avenge her death. After sleeping with Tina, Jimmy goes downstairs to get a bottle of wine. Jimmy then gets the corkscrew pinned to his hand and a meat cleaver to the face. Tina noticies Terri's bike and gets grabbed by Jason, who defenestrates Tina. While a stoned Ted watches stag films with a film projector, he gets too close to the projector screen and is stabbed in the head with a kitchen knife from the other side. Jason then goes upstairs where Doug and Sara finish making love in the shower. After Sara leaves, Jason kills Doug by crushing his head against the shower tile. When Sara screams upon finding Doug's body, she tries to escape only for Jason to drive a double-bit axe through her chest. Worried about Tommy, Trish and Rob return to the house, discovering the teens' bodies.

Worried for Tommy's safety, Trish and Rob return to the house. They then go next door to investigate and discover the teens' bodies. Gordon flees, and Rob is killed by Jason in the basement as Trish runs home, taking Rob's machete with her. She and Tommy barricade the house, but Jason breaks in and chases them into Tommy's room. Trish lures Jason out of the house and escapes, then returns home and is devastated to learn that Tommy didn't run away. She senses Jason behind her and tries to fight him off with the machete but is overpowered. Tommy, having disguised himself to look like Jason as a child, distracts him long enough for Trish to hit him with the machete, but she merely whacks off his mask. As Trish stands horrified at Jason's deformed face, Tommy takes the machete and strikes it in the side of his skull, causing him to collapse to the floor and split his head upon impact. When Tommy notices that Jason's fingers are slightly moving, he continues to hack at his body screaming, "Die! Die!" while Trish repeatedly yells out his name.

At the hospital, Trish is visited by Tommy. He rushes in, embraces her, and gives a disturbed look while staring into the camera.
