Jason Voorhees

Jason Voorhees is the central antagonist of the Friday the 13th franchise, being a hockey mask-donned serial killer who relentless hunts down anyone who dares trespasses on his territory.

Childhood
Jason Voorhees was born on Friday the 13th 1946 with hydrocephalus, that caused him to be mentally and physically disabled. As an outcast, Jason's only friend was his mother Pamela, who educated and cared for him until she was forced into a job as a cook at Camp Crystal Lake. While the camp counselors were too busy having sex to pay attention, the sadistic children of the camp bullied Jason until they pushed him into a lake. Jason could not swim, and he drowned, mentally destroying his heart-broken mother. Due to this tragic incident, Camp Crystal Lake was shut down, but years later it was reopened. This angered Pamela so much that she murdered all counselors in order to get it shut down. However, the last surviving counselors sliced her head off with a machete, putting an end to her massacre. Somehow, this event resurrected Jason and spent the rest of his life guarding the lake.
