StarFan13 has short brown hair with part of it tied in a small ponytail with a red scrunchie and bangs to the left and right of her forehead, similar to Star's own hairstyle. She has brown eyes, red square-rimmed glasses, a hot pink headband with a pair of cardboard cones pointing upwards, and pink hearts crudely painted on her cheeks. She has a short pug-like nose and a slight overbite, and she wears braces.
StarFan13 usually wears a lavender T-shirt with a yellow star, what seems to be a backpack with a pair of wings attached, a turquoise skirt, hot pink pants, and purple shoes.
StarFan13 has the typical characteristics of a fangirl: excitable and fixated on the subject of her fanaticism (Star Butterfly). She often tries to mimic Star's appearance and interests, like copying her favorite color in "Sleepover".
As her fan, StarFan13 gets very excited whenever Star is around her or talks to her. She and Star seem to be on good terms, since their interactions have been friendly, and Star seems somewhat flattered by StarFan13's admiration of her. In "Sleepover", StarFan13 states she has a crush on Star. She is also one of the few friends that Star called for moral support in "Starcrushed".
