Like all vampires, Riley is beautiful and striking. He has always been large and strong for his age, even as an infant, and he will continue to be so throughout his life. He has his father's dark hair and his mother's chocolate brown eyes. Similarly to his brother Jensen, he wore his hair long while he was a teenager, but later cut it. His eyes turn red in bloodlust, when his fangs emerge. His skin was originally pale, like most of the family and most type 2 vampires, but it has unusually darkened before lightening a little again.
