 Doug Wood, who designed the facial expressions of the "Half-Life 2" G-Man model, wanted the player to never quite know what side the G-Man was on by giving him ambiguous facial expressions.The G-Man appears throughout the series either in monologue scenes that occur at key points in the story or in live gameplay, where he can be seen briefly in far-off background areas or locations that the player cannot access until later in the level where he has disappeared.The character has the appearance of a middle-aged, light-skinned male with a tall and thin physique, pale/chalky skin, dark brown hair shaped in a military-style crew cut with a prominent widow's peak, blue-green eyes, a purple tie and usually holding a briefcase.
