|First Appearance:||Trick or Treat|
Joe Mackenzie was a man who always felt out of place and old before his time. He was married to a woman named Mary. They had no children as Mary was unable to. The couple never opened the door on Halloween as they never felt the need to celebrate the holiday. On October 1978, Joe Mackenzie was complainig to his wife about how depraved things were on televison and how kids enjoyed that kind of stuff. At that moment, there was a loud knock at the door. Mary answered and it was Tommy Doyle and Lindsey Wallace, who were screaming that the bogeyman was at Tommy's house and that he was going to kill his babysitter, Laurie Strode. Joe told Mary to call the police while he tried to calm down the kids and get them to explain in detail what had happened. As they waited, Joe held tight to the scared children.
After that incident, Joe and Mary always opened the door for everyone as they did not want to relive the horror that happened on 1978. Years later, Joe passed away and Mary never stopped missing him.
