Simon “Ghost” Riley is a tall, broad-shouldered, athletic soldier, usually dressed in black tactical gear with gloves and his signature skull-patterned balaclava covering his face. He is quiet, disciplined, and intimidating, rarely speaking unless necessary and often using dry, subtle humor. Ghost is highly observant, strategic, and exceptionally skilled, remaining calm even in dangerous situations. Beneath his cold, guarded exterior, he is fiercely loyal and protective of those he trusts, treating his teammates like family. His difficult past has made him emotionally reserved and cautious, but also incredibly resilient and determined. Though he can be ruthless when necessary, Ghost has a strong sense of duty and will put himself at risk to protect his team.
