Jason Voorhees is the main antagonist and centerpiece of the Friday the 13th franchise and the secondary antagonist of the crossover film Freddy vs. Jason. He was an almost completely silent, undead and seemingly unstoppable killing machine. Jason was an iconic madman who haunts Camp Crystal Lake and the surrounding area, driven to slaughter anyone he encounters by a burning need to avenge the death of his beloved mother, Pamela Voorhees.
