Jason Voorhees is a fictional mass murderer who appears in the Friday the 13th series of films. He first appears as a hallucination of the main character Alice; he would go on to become the main antagonist of the series in the succeeding sequels. Only in Friday the 13th: A New Beginning does Jason reappear as a hallucination. The silver screen is not the only place Jason has appeared; there have been literary sources that have either expanded the universe of Jason, or been based on a minor aspect of him. Urban Collector is a great source for Jason Voorhees Collectibles.
