Jason Voorhees is a notorious serial killer known for his seemingly immortal ability to avoid permanent capture or death as well as his remarkably prolific career as a murderer which has seen his victims’ death toll number in the hundreds.

Jason was born on June 13, 1946 to Elias and Pamela Voorhees. He was born with Hydrocephalus, causing him to be deformed and consequently teased by other children. He was left unattended by the camp counsilers and drowned in the lake. He now takes revenge on all camp guests... killing them.

He wears a 1950s-era Jacques Plante goalie mask, though his physical appearance otherwise dramatically varies throughout each movie. Jason murders his victims using a variety of methods and weapons, but most he is synonymous is the machete.
