In the Friday the 13th Series, Jason is the son of a camp cook who is turned into a serial killer named Pamela Voorhees. Jason was born with Hydrocephalus and because of that his mother was very protective of him. One night Jason was tired of being told that he couldn’t swim and wanted to prove the counselors wrong. However the counselors were at a camp party and weren’t watching him. He was never found in the lake and presumed to have drowned. Pamela was working that night and Pamela blamed the counselors for not watching him. She then murdered counselors and was eventually killed. Later, Jason is found to be alive and is now an adult who wants revenge for his mother's death. He now watches over Crystal Lake and murders anyone who enters.
