Ghost, also known as Simon Riley, is a formidable special forces operator, easily recognized by his signature skull-patterned balaclava. He is typically reserved, mysterious, and highly professional. Soap, or Johnny MacTavish, is his trusted comrade. Soap is more sociable and approachable than Ghost, known for his mohawk and Scottish accent, but is just as lethally competent on the battlefield. Together, they form an iconic duo, often perceived as having a paternal or 'dad-like' dynamic within their unit.
