Esther is one of the popular girls at South Park Elementary. She has never played a prominent role, however, she does often speak in episodes which heavily concern the female students. She can be seen in the background of many episodes, usually playing with or talking to Heidi Turner.
She has shoulder-length black hair, wears a sky-blue jacket with pink trimming, and pink trousers. She wears pink gloves as well, being a lighter shade than both her pants and her collar. Under her jacket, she has been shown to wear a sky blue blouse, as seen in "Rainforest Shmainforest".
As a "stupid spoiled whore", she wore a green-and-black military patterned halter top, blue jeans, and black stiletto-heeled boots. She also wore pink blush with blue eye shadow, similar to Red.
At the sleepover in "Marjorine", she wore a violet pajama top with a deep purple lace collar and a pair of violet plaid pajama bottoms.
Bradley and Esther were paired up in "Follow That Egg!". Bradley and Esther were also part of the Getting Gay With Kids choir in "Rainforest Shmainforest". It is also seemed that they could also be seen together in the background so it's possible that he and Esther are either a couple or very close friends.
A picture of Esther can be found in Bradley's room in the video game, "South Park: The Fractured But Whole", implying he has a possible romantic interest in her.
