In the mirror universe, Haffley was a male Terran and a member of the MACO detachment aboard the ISS Enterprise (NX-01) in the 22nd century, with the rank of sergeant.


He had transferred to Enterprise from the ISS Invincible, and a week later, killed fellow Sergeant McCain, personal bodyguard to Captain Travis Mayweather, and also attempted to kill Mayweather. Haffley was instead killed by Mayweather. (ENT - Mirror Universe novel: Age of the Empress)

It is unknown if Haffley has a counterpart in the primary universe.
