Best described as a grim anti-hero, Shadow has a strong sense of purpose and pursues his goals by any means necessary. He possesses a willingness to do whatever it takes to achieve these goals once he has set his sights on them, including using lethal force. This natural vehemence, however, tends to blind him with anger and make him prone to reckless decisions. It can also cause him to hold grudges, to the point where, if the object of his grudge is in sight, he is blinded to everything else; after being bested by Starline at the White Park Grand Chateau, Shadow decided to chase after him while ignoring not only Rouge and Tails being captured, but also an avalanche that would have injured or even killed everyone else. He also does not tend to take others into consideration, and sometimes his desire for revenge overwhelms his own sense of safety. Being an anti-social lone wolf, Shadow is generally not in favor of team-ups either; although he may occasionally cooperate with others, it is typically for his own reasons and does not guarantee that he is willing to follow orders. He also often leaves without saying goodbye or thanks.
