Shadow is an anti-hero, meaning he does some good things for bad reasons (or occasopnally bad things for good reasons). He rarely helps G. I. Unit: 5, but always turns to Red Dragon. He is called Shadow because he can sneak in to any facility and take things without anyone knowing. He also wears all black (including black face-paint) and a cape. He knows where the G. I. Unit: 5 members live, but he does not tell Red Dragon.
