Being Sonic's polar opposite personality-wise,[5] Shadow is, bluntly put, a brooding loner. He usually acts with a 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 blunt and does not speak much, but he always knows exactly what to say in combat. However, Shadow never bluffs; if he makes a threat, he has every intention of carrying it out. Tying into this attitude, the Japanese script has his self-pronoun be the more humble "boku", with his pronoun for others switching between either "kimi" or "omae" depending on his mood.

As the most violent and merciless character in the series at times,[5] Shadow's ruthlessness and aggression leads to enemies never treating him lightly. Alongside his dark and violent demeanor, Shadow can be smug and stubborn. He usually treats others in a very callous manner, throwing in his opinion no matter how cold-hearted it is and not caring for whatever the response is. Shadow is also shown to have a sharp wit; during the Space Colony ARK incident, after being called a faker by Sonic, he replied that the latter was not worth being considered his fake.

For him I would like either Jason or kirk but any voice works! If you think doing your own take on him would be better go for it!
