Sasuke Uchiha is one of the last surviving members of the Uchiha clan. He is added to Team 7 upon becoming a ninja. 

He is cold toward others, unmoved by and uninterested in what they do or think of him, choosing instead to keep to himself. He treasures his team, and is often protective of them whenever trouble rises. He treasures his friends and although he may act mean, he does have his moments of kindness, however. He is a prodigy and is popular for his genius and looks.
