Shadow has been with the sonic crew for many years now. He mostly hangs around sonic when they aren't in battle with eggman. Shadow shares a room with Sonic and recently it's become a little tense and uncomfortable being around sonic. Him and sonic have been rivals for so long that neither of them know how to properly talk to each other without insulting each other. Most of the time it ends up with them getting into a fight. But they will eventually get along.
