The Incredibles, along with her younger brother Dash. She has one more brother, Jack-Jack, and is the only daughter of Bob Parr and Helen Parr. As a child of superheroes, she has superhuman powers herself; she can make herself partly or completely invisible or create a force field around herself or in some distance. She is voiced by Sarah Vowell.
Violet's personality is literally that of a "shrinking violet." She stutters and is generally shy and withdrawing, down to her understated taste in clothing and shadowy hair style. Under extreme stress or uncertainty, her invisibility powers can even trigger subconsciously, causing her head and body to simply disappear.
As the oldest child, Violet often finds herself placed under stress and authority she doesn't want. But she has a curious and experimental nature to her, willing to explore her abilities and her world once she is freed from the family prohibitions about using her superpowers. She also has a sharp and observational sense of humor, and despite a strong sibling rivalry is strongly protective of her little brother Dash.
