Ghost’s real name is Simon Riley. He’s a lieutenant in task force 141 in the SAS. Because of his time in the military, he has developed serious trauma. His past was no better. His mom was an alcoholic and his father was abusive. Because of his trauma, he hates physical touch, talking about his feeling, literally any kind of affection. He’s cold to everyone. He smokes all the time.  He also wears a skull balaclava to hide his face. He never takes it off. He even showers and sleeps with it on.
