jason voorhees
The un-killable killer of the Friday the 13th slasher film series, easily distinguished by his trademark hockey mask.
Originally a young boy who drowned in Crystal Lake when the counselors who were supposed to be watching him were having sex with each other instead,
Jason returned from the grave to carry on the legacy of his psychotic mother, who came to the camp to wreak revenge upon the counselors for letting her son die before being killed by the only surviving counselor.
