Peterson Josiah "Peter" Fox (born October 31st) is the eldest child of the Fox Family. A 16-year-old junior, he is regularly shown wearing a blue/purple and white baseball cap with the letter A on it, as well as a grey hooded sweatshirt and blue jeans. Occasionally, his cap has an "H" instead of an "A", but only as a benchwarmer for the high school baseball team. He is only seen to take off his hat in the first few books for formal occasions such as church or the prom.
