Paul is prone to angry outbursts which cause him to burst into his wolf form. Paul is one of the bigger wolves, and has dark gray fur. He is the most volatile pack member, and becomes so enraged when he learns that Jacob has told Bella about the pack that he bursts into his wolf form and attempts to attack her. He later seems to have no ill feelings towards Bella or Jacob, though Jacob, Leah, and some of the other wolves find him annoying. Early in Book 2 of Breaking Dawn, Paul is shown to have imprinted on Jacob's older sister, Rachel. This annoys Billy and Jacob because he is always at their house eating their food; however, Billy is happy that Rachel is staying at home longer because of Paul.
Paul is portrayed by Alex Meraz in the The Twilight Saga: New Moon.
