Jason Voorhees is the main villain of the Friday the 13th slasher film series and its remakes as a murderer for revenge. Either as a figment of imagination or in the flesh, Jason appears in every novel, comic, and film. Jason stalks and kills the Camp Crystal Lake, feeling a burning need to avenge the death of his beloved mother, Pamela, and the abuse they received, largely due to Jason's deformity. He has only one copycat killer, Roy Burns.
