Petey is known for being characterized by his smart wits and his hot-headed temper. He has a way with words in the sense of getting what he wants, which was very commonly used as a manipulative tactic to invoke his evil plans in earlier books as a villain. One of his main weaknesses, however, is getting very irritated over seemingly small inconveniences and immature or ditsy behavior from others. His anger issues have visibly shown to cause him moderate amounts of stress.
