Sophia "Sophie" Martinez (portrayed by Madison Pettis) is the daughter of President Richard Martinez. She is a mischievous 8 year-old girl who loves to annoy people, especially Cory. She has two best friends, Haley and Tanisha, who often compete with Sophie at random things, like class president. She is also known as "America's Angel" by all of America, (though she is not one to Cory) and when her nickname is mention she often responds using her catch phrase: "That's what they call me!" She is mischeivious, but also looks up to Cory and loves him like a big brother.
