Sodapop has silky, dark brown hair that he combs back but still looks slightly messy. He's got dark brown (recklessly, dancing) eyes and a goofy grin.

Sodapop, sometimes called “Soda,” is the middle of the three Curtis brothers. He is energetic, disinterested in school, and handsome. Ponyboy describes his idolization of Sodapop, he says his brother “gets drunk on just plain living,” a quality he deeply admires.
