Major Clifford Zmeck is basically the evil version of the Post-Crisis Captain Atom. Having been rightfully incarcerated for violent crimes (especially against women) and liberated to take part in the same military program that gave Nathanial Adam his quantum-based powers, Major Force is one of the most dangerous sociopaths on the U.S. government's leash. He later became well known for killing newly minted Green Lantern Kyle Rayner's girlfriend Alexandra DeWitt, the original (and literal) woman in a refrigerator. Major Force also murdered the once and future Green Lantern Arisia, and was himself executed by Guy Gardner, but neither demise stuck.
