John Freeman is, nominally, an office and lab worker who owns two motorcycles and is a skilled motorcyclist and marksman, able to do "a backflip and land" and shoot bosses in the eye with "wepon". He also possesses great fighting skills, physical strength, and endurance: he is able to kill many Combines with "bear" hands, and endure multiple gunshot, knife and rocket wounds. He is the brother of Gordon Freeman, an MIT-educated theoretical physicist and all-round badass. He has poor vocabulary.
