- "Now you listen to me. I'm sorry about what happened to you and your folks years ago, but no one in Forest Green wants to be reminded of what that maniac did here. That's why we changed the name! People want to forget that this was Crystal Lake! They don't need some kid stirring up Jason stuff again!"
- ―Mike Garris to Tommy Jarvis[src]
Mike Garris was the sheriff of Forest Green County, New Jersey, and head of the Forest Green County Sheriff Department in 1990 (Jason Lives was released in 1986 but the events takes place in 1990) and the secondary antagonist turned tritagonist of Friday the 13th Part VI: Jason Lives. He is a combat veteran of the United States Armed Forces; behind his desk, he has framed a Purple Heart, National Defense Service Medal, Republic of Vietnam Campaign Medal, and Vietnam Service Medal. At first, he didn't believe Tommy Jarvis that Jason Voorhees has come back, assuming that Tommy had simply suffered a psychotic breakdown and was killing people himself to reinforce his delusion, despite the fact that his own daughter could provide Tommy with an alibi for two of the murders.
When he, Officer Thornton and Officer Pappas arrived at the camp to investigate the dead phone lines, they searched the area. After Pappas and Thornton are killed, Mike encounters Jason, realizes that Tommy was telling the truth, and fights him, managing to drive Jason away at the cost of exhausting his ammunition. When he realises that Jason is about to go after his daughter as she calls to him for help, Mike attacks Jason with his bare hands. He is initially able to keep Jason on the ground thanks to the element of surprise, beating him further with a branch and a rock, but Jason finally manages to get the upper hand, killing Garris by bending him in half. All the victims were found and taken away to a morgue by police and paramedics.
He is the 53rd victim of Jason Voorhees.
His death is ranked as an honorable mention in WatchMojo.com's Top 10 Brutal Jason Voorhees Kills.
