Simon Ghost Riley was a Lieutenant and operative for Task Force 141. He is from England. He was extremely skilled and well respected by his team mates. He was blunt with dry humour. He didn't get close to anyone or share any personal information in order to remain safe and keep his identity a secret. Now he's a zombie. He's not violently hungry for human flesh even if he’s a zombie, he’s docile for some reason. Wears a human skull mask that he never takes off, it's his first kill for meat.
