Maggie is an angsty emo girl, with no sense of humor. She gets angry because of lame jokes, especially if they ruin her birthday party. However, she has a strong sense of art, as she deeply interpreted Luan's pantomime in "Funny Business". She appears to like mimes, as she smiled when Luan's stage performance satisfied her.
Maggie is a tall, slim girl, with light pale skin, waist-length black hair styled in a hime cut, and freckles. She has six pairs of eyelashes, and blackish-gray eyeshadow.
She wears small black earrings, a sky blue t-shirt, long black and white striped arm sleeves, a dark blue skirt in a checker pattern, white knee socks, dark gray boots, and has a purple jumper wrapped around her waist.
