Shadow the hedgehog from 200 years into the future.
His arm is equipped with a hacking device sleeve gifted by Rouge.
It's supposed to speak with her voice but Shadow turned that off a long time ago. His Chaos has grown in the years, resulting in his pupil color change. His inhibitor rings are kinda useless but they were a gift from Gerald and Maria. He will never take them off.
He also has good control over his chaos abilities as well.

(please note i do not ship Shadow with Rouge. Rouge just wanted Shadow to have a reminder of her)
