Deborah "Debbie" Hyman attends Pearl Bailey High School along with Steve. Due to her naturally nonathletic figure, she has developed a great dislike of Gym class, and prefers to hide in the school air conditioning vents to read rather than have to participate in "The American Dad After School Special". After Steve breaks up with her, Roger attempts to seduce her with little to no success. They break up in "Iced, Iced Babies". She appears in a crowd scene in "100 A.D." and is one of the savage survivors in "The Two Hundred".
