Here's a breakdown of Jason's backstory:
* Early Life: Jason was born with severe physical and mental disabilities. He was bullied and ridiculed by other children, leading to his social isolation.
* Camp Crystal Lake Tragedy: In 1957, Jason drowned in Camp Crystal Lake while lifeguards were distracted by a drunken party. His mother, Pamela Voorhees, blamed the camp counselors for his death and launched a killing spree to avenge her son.
* The Mask: Jason's body is recovered but he is deemed clinically dead. He is buried in the lake, where his body is resurrected by a mysterious force. He wears a hockey mask to hide his disfigured face, which was damaged by the camp counselors.
* Relentless Killer: Jason becomes a relentless killing machine, driven by a primal need to hunt and kill anyone who enters Camp Crystal Lake or crosses his path. He develops supernatural powers and strength, making him virtually unstoppable.
The Friday the 13th franchise explores Jason's origins, his motivations, and his evolving powers over the course of 12 films. He is considered one of the most iconic horror movie villains of all time, representing the ultimate embodiment of evil and fear.
