Thing is a very strange young boy. He changed from being a knowledgeable young boy to one with very little intelligence. Thing has strength within him, but he is usually too clueless to battle unless his friends are really in trouble. He is commonly seen with a large smile on his face as well as some kind of dirt or food stains on his clothes or face. Thing likes training and believes that if he stops moving, he will become weak, so is often found running around.
