Lizzy plays a more prominent role in "Cartman's Silly Hate Crime 2000" when she challenges the boys to a sledding competition. Despite her apparent death at the end of the same episode, she made numerous cameos in the background until the twelfth season.
Lizzy wears a rose pink parka that covers most of her face, similar to Kenny McCormick's parka. However, Lizzy's mouth can be seen. Her parka has gray fleece padding and buttons up. She also wears gray gloves, dark gray pants, and black shoes. To date, her hair has never been shown onscreen.
Lizzy seems to be very stubborn and competitive, as she challenges the boys without hesitation when they do not hand over the sleds, exhibiting confidence in her team's ability to win a sledding competition against them. She enjoys taunting the boys and coming up with creative insults, such as "Butt Pirates", "Rump Rangers" and "Donut Pinchers". She rubs in their faces when they lose Cartman as a fellow sledder and reminds them of the upcoming competition, including calling them on a home phone to harass them. Her sexually advanced vocabulary also suggests a vulgar sense of humor uncommon among female characters in the show.
Lizzy was depicted alongside Bebe Stevens, Sally Turner, and Esther in her speaking appearance, where the three girls made up the members of her sledding team; they were also seen at her house when she called the boys up to taunt them.
