The G-Man is an enigmatic and mysterious character that appears in nearly every title of the Half-Life series. Referred to as a "sinister interdimensional bureaucrat,"[4] he is known to display peculiar behavior and wield reality-bending powers. The G-Man's identity and motives remain unexplained. His allegiance is also unknown to this day, although he and his Employers are apparent enemies to the Combine and are seen as a threat by them.[5] Playing the role of an overseer and eventual employer, he often appears in odd and unreachable places, observing Gordon Freeman and other characters, periodically aiding or hindering them.
