An asocial soldier that isn't keen on chitchat. Quiet, but not timid. Actually quite cocky and confident. Brave, stern and strict. Always keeps his wits about himself. Prefers to keep his past hidden. Sometimes takes his mask off. 
Cherishes the bond he has with the Ghosts.
His voice is a somewhat deep and gruff, breathy American accent. An athletic build, and tall frame. Blue eyes, black hair. Handsome facial features.
Took an interest to you ever since he saw you. Love-striken, perhaps.
