Heather

Heather is the main antagonist (or at least the mean girl) of season one. She is the popular Queen Bee/jealous shrew in the Screaming Gophers. Heather enjoys talking about her popularity, or her appearance, but truly dislikes her evil little brother Damien (reference to "The Omen"). Heather joined Total Drama Island because she believed that it would her to become a world famous celebrity. In middle school, she was brace-faced, fat, ugly, and above all a middle school reject. She intends to win the competition with dirty tricks, cheating, and sabotaging the other campers. Her entire family seems to despise and fear her (as a message from home showed them moving all her stuff out of the house and shivering while saying that they miss her). She first forms an alliance with Beth and Lindsay to get to the final three, using Lindsay for stupidity and Beth for her desire to be popular. She first bribes everyone on her team to vote Justin off instead of her. She has an extreme distaste for Gwen and Leshawna, which begins in "Not Quite Famous" after she reads out Gwen's diary, revealing Gwen's crush on Trent. In "X-Treme Torture", she becomes embarrassed after driving a seadoo and while attempting to cut the rope Harold was holding onto, a tree branch snagged her top and Heather remained completely topless. Harold started making a big deal out of it. In the next episode she tries to get Bridgette to join her alliance, but Bridgette says no. An the next episode, Duncan reveals he thinks Heather did something to eliminate Courtney, although Courtney was eliminated because of Harold, not Heather. Eventually Heather gets Izzy to join the alliance with herself and Lindsay. She then spots Gwen and Trent making out. She forms a plan to get one of them voted out, so she gets Trent to turn on Gwen by telling him that Gwen is using him. She makes out with Trent angering Gwen. In the end, Heather won invincibility and the group voted out Trent, meaning her plan worked. Heather betrayed Lindsay in "That's Off The Chain!" Although she does make it to the finale three with Gwen and Owen, they gang up on her in the dare challenge when Owen splits his Get Out of a Dare Freebies with Gwen. Stuck without any freebees and Gwen and Owen loaded with them, Heather is forced to face all the dares herself (thus paying for all the harsh things she did to the other campers), she is finally eliminated when she refuses to complete the challenge and is eliminated because of Lindsay's dare to have her head shaved, even though she ends up getting it shaved anyway. In "If You Can't Take The Heat...", Heather threatened that she would cut off Lindsay's hair while she was sleeping if she betrayed her again like what happened to Beth. Say the least karma finally caught up with her. She was set to be voted off several times, but someone else always messed up and got voted off instead. Examples: Justin (convinced team), Cody (got mauled by bear), Beth (put curse on team), Trent (won invincibility and either Trent or her was going to be vote off), Bridgette (invincibility), Lindsay (invincibility), Leshawna (Chris cheated and when the voted off campers said Leshawna's name it counted as a vote against her. Heather returns to the show in the final episode (along with everyone else).  She makes a final attempt to bring down Gwen by fixing some obstacles in Owen's favor.  Though Owen wins, Heather's pride (and somewhat good mood) is lost when LeShawna finally snaps and locks Heather in the Confessional stall (where Owen just had explosive diarrhea after he ate her cupcake which was meant for Gwen).  Not only does Heather not get to see the winner, but she is bathed in Owen's gas (thus really starts to smell). Heather pouts for the rest of the episode, until Chris is dunked in. Gwen tells Heather that she must be happy to see him dunked. Heather slowly smiles (happily) and says "Yeah...a bit." This might be a sign that perhaps Heather has finally made peace with Gwen (and some of the other campers) and will perhaps return to Total Drama Action as either an anti-hero or friend. Though it is possible that she was just happy for the moment and will return as the antagonist of Total Drama Action.

Heather has done many sabotages in an attempt to win the contest. She stole Eva's Mp3 Player (causing Eva to break out in rage and thus getting eliminated), she read Gwen's diary and reading to all the campers (and show viewers) and even tried (but failed) to sweet talk Chris (as seen in the beginning when she acts sweet towards him). One of Heather's many bad deeds is bringing apart couples (claiming that its just another word for alliance). One of her worst attempts was bringing apart the Gwen and Trent by kissing Trent and breaking Gwen's heart (and trust in Trent). She has also interfered in many other relationships, including Lindsay and Tyler, where she constantly accused Lindsay of betraying her own team and even being abusive towards Tyler. She has also (although unintentionally) interfered with the brief Harold and Leshawna, where she accidently exposed her breasts to Harold during a mud race. This action was really a problem for her, as Leshawna responded with anger towards her.

Audition tape
In her audition tape, Heather walks out of the shower with a towel and starts talking about how she will not be nervous if she was on the show. She also talks about how pretty she looks, and she adds that if they pick her, she promises high ratings. She then throws off her towel, off-screen.

Video log
On Cartoon Network, Heather's Parent's send her a video log. It starts with her parents dancing with party hats before telling their daughter how much they miss her. All the while a group of movers carry her stuff past them.

Trivia

 * She is one of (if not "the") the most hated campers on the show along with Noah.
 * Heather actually has seen reality shows before (as she said in the second episode) and thus she has picked up on some strategies for Total Drama Island.
 * In the final episode, she is completely bald, but when she gets her head shaved, there were several patches of hair left, meaning she shaved the rest (or it was lose and fell out).
 * Despite Heather's dislike of Gwen, she does not wish her dead, as she reacted with extreme fear (like everyone else) when Gwen was cornered by the psycho killer.
 * Heather does seem to show some signs of improved compassion throughout the show as she started to apoligize to Lindsay and Beth when she was stuck alone in Camp Castaways.
 * She is one of the few people to show some form of nudity, (her boobs) others include Owen,Izzy, and Harold.
