Maggie Main 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 pale skin, waist-length black hair styled in a himecut, and freckles. She has six pairs of eyelashes, and blackish-gray eyeshadow.

She wears black earrings, a sky blue t-shirt, long black and white striped arm sleeves, a dark blue skirt in a checker pattern, dark grey boots, and has a purple jumper wrapped around her waist.
