She stands at 160cm (5'3') and weighs 41kg (90lbs). Violet is a 14-year-old teenage girl with a slender build, small waistline and long legs. She was also the one who bravely suggested she and her brothers needed to take action after their parents and Lucius were in danger. However, she ultimately develops a sense of maturity and responsibility. She also displays a much broader range of emotions, typical of a girl her age: throwing tantrums, acting awkward and at times sinking into a very sad mood. In the sequel, Violet retains her new upbeat and confident attitude. She also cares deeply for Jack-Jack, constantly looking out for him and being amazed by his powers. She also has a sharp and observational sense of humor and is very kind and caring, and despite a strong sibling rivalry, she is strongly protective of little brother Dash. Violet is shown to possess a curious and experimental nature, willing to explore her abilities once she is able to use her superpowers when needed, without being prohibited by her parents.
However, near the end of the movie, Violet gains enough confidence to ask her crush, Tony Rydinger out on a date during Dash's track and field meet. She also uses her invisibility as another way to hide from her peers. Throughout the first half of The Incredibles, Violet is symbolically hiding behind her long hair, as a way to hide from the world.
