Jason has had the most movies. Ten movies where he's the villain, one where he fights Freddy (Freddy Vs Jason) and a remake of Part 2/Part 3 where again, he's the villain. In those movies, he managed to kill 146 people, that's about double to quadruple the amount of kills ANY other horror icon since the 60's-70's has ever gotten. Then, there's the fact that he's unkillable. He's been shot with a shotgun consecutively, literally blown up into nothingness and dragged down into hell. Jason also supposedly drowned in the first movie and that didn't stop him from exacting his revenge. Which that's where the theory of "Pamela Voorhees used the Necronomicon (grimoire by H.P Lovecraft) to resurrect her son Jason. Thought that theory has never been true nor false
