Kelly is a 15-year-old tomboyish sassy teenager that showcases stereotypical characteristics of a teenage girl far to the extreme. 
Sporting a blonde shag haircut, purple eyeshadow, pink-striped tights, and a valley girl accent and manner.
She is extremely self-conscious and is determined to fit in with the cool kids at school and maintain a cool reputation. The smallest of things provoke Kelly's great fear of being embarrassed in front of her friends.
