|First Appearance:||Halloween: Resurrection|
Harold was a mental patient at Grace Andersen Sanitarium. He had an obsession with serial killers such as John Wayne Gacy and Michael Myers (whom he idolizes). He had the habit of escaping his room but he was harmless and was on good terms with the security guards. On October 31 2001, Harold had managed to escape once again and was wearing a clown mask, trying to be John Wayne Gacy. Willie Haines escorted Harold back inside his room.
A couple of minutes later, he saw a shadowy figure walk past his room and, later in the night, that same figure came into his room. The figure was Michael Myers, who handed Harold his bloody knife and left the room while Harold told himself the history of Michael, overjoyed that Michael had returned from hiding. Little did Harold know that Michael only gave him his knife to frame him for the murder of his sister, Laurie Strode, and of the security guards Willie and Franklin which followed. It is unknown if he was cleared or not.
- Harold is one of the very few fortunate people, if not the only person, Michael does not attack or kill upon meeting.
