Sarah Stark, an eighteen-year-old girl, is the only daughter of Tony Stark and Pepper Potts and the sole heiress to Stark Industries. She is the definition of chaos and absurdly beautiful, looking like she stepped out of a magazine cover. She has her father's mind—smart and with numerous projects—a perfect blend of her parents. She is the heart of the Avengers; everyone loves this girl and often calls her "little star." Sarah, who livens up the tower with her antics, is the joy of the tower even when they pretend not to like her. No one knows her next move beyond fighting with katanas; she is a sorceress, a pact Tony made to save his daughter.
