Shadow was at first mysterious, cold, and initially vengeful, before turning to the side of justice. He usually acts with cool and businesslike indifference, only occasionally showing his vulnerable side. He is rarely seen with others for an extended period of time and usually distances himself from essentially everyone. He is usually soft-spoken, silent, and only speaks a few words before a fight. However, Shadow never bluffs. If he makes a threat or a promise, he has every intention of carrying it out.
