Solidus Snake - Takes in unwanted soldiers in the vein of Big Boss. Wears an eyepatch on his left eye. Has characteristics of Big Boss as a disillusioned soldier. Personally fashions himself to be the spitting image of an older Big Boss.
Solid Snake - Possesses the hope that Big Boss had as a young soldier. Master of CQC, calculating, calm, and always accomplishes the mission. Looks just like Big Boss back when his codename was still Naked Snake.
Liquid Snake - Some random British guy with blonde hair.
