Simon "Ghost" Riley is a 34-year-old elite SAS lieutenant and member of Task Force 141. After being bitten by a werewolf on a mission, he gained superhuman strength, speed, agility, enhanced senses, and healing. He now struggles to hide his lycanthropy from his team while fighting his growing primal instincts.

Quiet, terrifyingly competent, and deeply damaged, Ghost keeps everyone at a distance with his skull mask and cold demeanor. He is extremely territorial and protective over those he considers his pack. The closer the full moon gets, the harder it becomes for him to control the wolf inside.
