*Heather was a camper and the main antagonist of Total Drama Island as a member of the Screaming Gophers. She later returned as a cast member in Total Drama Action on the Screaming Gaffers and was one of the finalists in Total Drama World Tour as a member of Team Amazon. She was seen with the original contestants on a yacht in the first episode of Total Drama: Revenge of the Island and had a cameo appearance in Up, Up and Away in My Pitiful Balloon. She returned as a camper for Total Drama All-Stars, being placed on the Villainous Vultures.

Heather was Total Drama's first antagonist. Famously manipulative and vicious, Heather knows what she wants and exactly how to get it. Her strategic smarts have proven effective, eliminating a record amount of contestants. She competes with her sights only on the prize money and not on making friends or finding love, using others at her advantage and only being kind when she may ultimately be benefited. This makes it difficult to differentiate her original, mean girl ways from her true heartfelt moments. Such an example is in Total Drama, Drama, Drama, Drama Island, when a tearful Heather tells Harold that she doesn't like "being mean all the time" and it's not fun "being the one everyone hates". Hawaiian Punch, in which she becomes ecstatic at the thought of being the "good guy", confirms that there is at least some truth to her lament. However, even romance is not enough to tame Heather's desire for victory, as shown by her relationship with Alejandro. Over the course of the series, though, her cruel behavior seemed to have toned down. She tried to warn others about a greater threat, sympathize with others, and even felt awful for accidentally causing someone's life-threatening injuries. However, this is all short-lived and she returns back to her more-aggressive personality in Revenge of the Island.

One of Heather's fatal flaws, at least in the beginning of the series, is her vanity. Portraying as a stereotypical rich and spoiled girl, Heather refuses to partake in any activities that may result in ruining her good looks, especially her hair, which earned the ire of one of her biggest rivals, Leshawna. Instead, she had other people do her work for her. One could say that until Lindsay's elimination in That's Off the Chain!, Heather shows little involvement in most of the challenges. This trait has since vanished after season one and she becomes more determined to win challenges by herself.

Heather is an Asian-Canadian girl with light olive skin, a small cleft in her chin, and jet black hair with dark gray reflections. She wears a burgundy red halter top, light army green short shorts with a black belt, and burgundy red slide wedged sandals. Her hairstyle changes throughout the show; during Island, it was waist-length, during Action she was bald and wore wigs, during World Tour she got hair extensions and had a short high ponytail, and during All-Stars she has a long low ponytail.

Her wigs changed throughout Island and Action: her first one was a long black mullet, her second was a long red cavewoman wig, and her third one was a black afro.*
