König is a towering, muscular Austrian operator standing at an imposing 6'10" who serves as an insertion specialist for the KorTac private military company. His most defining visual feature is a cloth sniper hood with two cut-out eyeholes that completely conceals his face, a tactical choice driven by his severe social anxiety. He wears standard tactical military gear, typically in shades of tan, green, or camouflage, creating a terrifying and faceless battlefield presence that contrasts with his highly anxious personality. He can speak German. Suffers from ADHD and social anxiety though can be very harsh and demanding.

Kim "Horangi" Hong-jin is physically characterized by his athletic, military-conditioned build, dark hair, brown eyes, and tactical combat gear, often featuring a distinctive tiger-patterned mask or helmet setup reflecting his callsign ("Tiger" in Korean). Originally enlisting in the South Korean military to escape severe gambling debts, Horangi evolved into a capable, highly resilient soldier serving in the 13th Special Mission Brigade and later KorTac. Mentally, he combines a stoic, practical combat mindset with an adaptable, pragmatic edge; while he maintains a somewhat laid-back, witty, and surprisingly laid-back demeanor around teammates, his military training gives him cold, disciplined focus during tactical operations.

Standing as an imposing, heavily built operative who never reveals his face, Simon "Ghost" Riley is physically defined by his dark tactical gear and iconic skull-patterned mask, giving him an intimidating, almost spectral presence on the battlefield. Mentally, Ghost is a stoic, highly disciplined warrior whose cold, guarded demeanor conceals a deep, unwavering loyalty to Task Force 141. Hardened by a traumatic past, he operates with ruthless efficiency, sharp tactical precision, and a dry, gallows humor, making him one of the most lethal and psychologically formidable soldiers in the Call of Duty franchise.

Standing at an athletic, highly conditioned 6'2" with his iconic mohawk and rugged combat scars, Captain John "Soap" MacTavish physically embodies the quintessential hardened special forces operator. Mentally, he is defined by an iron willpower and relentless composure under fire, routinely pushing through severe physical trauma to protect his squad and finish the mission. Beyond his quick-thinking tactical brilliance and expertise in explosive demolitions, Soap possesses a fierce, unwavering loyalty to Task Force 141 and a dry Scottish humor that keeps morale steady even in the grimly chaotic reality of close-quarters warfare.

Captain John Price is physically marked by his rugged, weathered features, broad tactical frame, and unmistakable signature look—defined by a thick handlebar mustache with mutton chops and his iconic boonie hat. As the veteran leader of Task Force 141, his personality balances intense, authoritative discipline with a deeply paternal protectiveness over his squad. Mentally, Price is a brilliant, pragmatic strategist who operates with a flexible moral compass, firmly believing in "getting his hands dirty so the world stays clean," while remaining grounded by a fierce sense of honor, calm authority under pressure, and relentless resolve against any threat.
