|“||What's with all the lovin'? Hello! It's called Total Drama, not Total Friendship!||„|
Courtney is the anti hero of Total Drama Island, the true main antagonist of Total Drama Action, the secondary antagonist of Total Drama World Tour and the tertiary antagonist of Total Drama All Stars.
In the first season, she was a control freak who constantly tried to be the leader of her team because she was a certified summer camp C.I.T. (Councilor in Training). She is very uptight about rules, which often bugged her team, but she was never voted off because she was such a good leader and was the reason for her team's success most of the time. She often yelled at other members of her team for giving up too easily, such as yelling at Tyler for his fear of chickens.
Courtney soon started forming an unlikely yet very chemical relationship with Duncan, the camp delinquent. He dared her to break some rules by stealing food from Chris's and Chef's tent and bringing it back to campers. When she ate too many cookies and threw up over the cabin porch, Duncan laughed at her and told her that she had a dark side. She told him that he wasn't her type, and he said, "Fine, enjoy a peanut butter-less life" to which she responded, "Fine, enjoy prison" and to which he said, "I will." Courtney then turned him around and kissed him. Harold witnesses this and uses this to get revenge against Duncan for always picking on him. Harold outright cheats by breaking the voting box and fills it with fake votes against Courtney. When Chris reveals that Courtney was going home everyone looked at each other, confused and said that none of them voted for her, but Chris said that rules are rules, and dragged Courtney kicking and screaming to the boat of losers. In a later episode where all the voted-out campers are shown to be trapped at a 5-star hotel for the duration of the competition, Courtney is seen beating Harold with a large metal pipe, even hurting Ezekiel and Noah when they told her to relax.
In the special following the supposed series finale, where the entire cast is sent on a free-for-all search for a case filled with one million dollars, Courtney became a villain for the first time as her true self has been finally revealed since early in the series, and she has not felt any sympathy for anyone she caused misery to or apologized for her actions. In her ruthless bid to get the case for herself, she threatens to let Owen, DJ, Tyler and Cody fall to their deaths for the case, leaves Duncan behind when he is injured retrieving the case and at the climax of the episode literally has the entire cast trying to take the case from her. As she is not in the water when the case is eaten, she does not qualify for the second season.In Total Drama Action, Courtney didn't appear for the first half of the season but was allowed back on when her lawyers sued the show for abusing her. As part of her lawyers' demands, Courtney was given unfair advantages in all the challenges and was allowed to eat real food with the producers while the rest of the contestants had to eat slop from the cafeteria. For the first few episodes she held a grudge against Duncan because she saw footage of him and Gwen flirting and getting close together, and their relationship was put on hold for a short while. Courtney took this advantage and brutally and aggressively does cruel things towards him in which she does not feel any sympathy or caring towards him whenever she abuses him. She kicks him in the crotch intentionally, uses him to win challenges for herself even if it means beating him up during the game, etc. But after a while (and a few accidental kisses) Courtney allowed him to date her again (which also came with a contract and a list of rules he had to follow and to do what she says), but after Courtney was finally voted off (by him), he threw away the rule book, but admitted that he still loved Courtney. On the finale when Duncan won, Courtney ran up to celebrate "their" victory and continued making out with him while confetti was thrown everywhere. In the other ending where Beth wins, she remains humiliated.
In "Celebrity Manhunt's Total Drama Reunion Special", "Duncney" is revealed to have broken up after a series of disagreements, but later in the episode they get back together once again. In the very first episode of Total Drama World Tour, Duncan quits the competition out of frustration with Courtney and Gwen's bickering and the fact that he is now expected to sing during the challenges. While Duncan is gone, Courtney starts to become nice again and she and Gwen gradually form something of a friendship until they find Duncan in London in Episode 13 and he reenters the competition, at which point Courtney's alliance with Gwen starts to be on shaky ground.
Gwen and Duncan kiss in the confessional bathroom after Chris intentionally sabotaged the lock so that something like this might happen, and Tyler walks in on them and witnesses it. At the start of the following episode, Courtney actually mentions that she is suspicious of Gwen and Duncan, but once Tyler reveals what he saw after being pressured by Alejandro, Courtney completely and undergoes a complete meltdown. She starts kicking and screaming at Gwen, accusing her of betraying her and repeatedly telling her "I HATE YOU!" She tells Cody to throw the tiebreaker challenge so she can eliminate Gwen, which only makes him try harder for Gwen, who he has a crush on. When Gwen tries to cheer for him, Courtney yells at her "YOU don't get to cheer!" When their team wins the challenge, Courtney voices her dissatisfaction with this and physically hits Gwen when she tries to celebrate.In the next episode, Courtney is seen throwing a childish temper tantrum at Duncan, throwing spaghetti in his face and calling him a "stupid jerk-face". Duncan tries to apologize, only for Courtney to kick him in the groin while throwing her tantrum on the floor. During the episode she flirts with Tyler, who is in a steady relationship with Lindsay, to make Duncan jealous, thus making her technically guilty of cheating just like Gwen and negating her only remaining excuse for her continued sadistic actions.
When the once-an-episode cue for a musical number appears, Courtney sings a song called "Boyfriend Kisser" about her hatred of Gwen. The song sequence shows Courtney launching nuclear missiles directly at Gwen, and Gwen being repeatedly smashed by falling boulders.
Later it is revealed that Courtney is actively trying to make her team lose just to get Gwen, who is supposed to be her teammate, kicked off. When they are tasked with retrieving an alien artifact from Area 51, Courtney tries to destroy anything she finds and when they are running back to Chris with an alien device in hand, Courtney intentionally trips Gwen with the intention of destroying it, but the object lands in Chris' hands and Team Amazon wins, which visibly frustrates Courtney.
More than a week has passed since all this happened. She grabs Heather and pulls her into a dark closet where she tells her to vote out Gwen, and when Heather calls her out for trying to lose, Courtney denies it.
Not only does Courtney lie about trying to lose, she does it again in the Australia challenge. She starts to flirt with Alejandro (who has also faked attraction towards multiple girls with boyfriends), at first to torment Duncan but soon she actually falls for him and agrees to support him and his team in the competition, stupidly not knowing about his true self. When Team Amazon loses and the elimination voting takes place, Courtney is seen repeatedly stamping Gwen's passport angrily in the confessional and has to be pulled out by Chef to make her stop. Sierra, who mistakenly believe that Gwen has romantic feelings for Cody, also votes for Gwen, while Gwen and Heather vote for Courtney. Cody was supposed to vote for Courtney, which would have eliminated her, but he was injured by a dingo at the end of the challenge and accidentally voted for Sierra instead. The vote came down to a tiebreaker between Gwen and Courtney, which is rigged by Chris against Gwen (involving something she is allergic to), and Courtney smiles widely as she hears her scream as she falls from the plane.
In the episode after that, Courtney continues to be romanced by Alejandro and once again tries to slow her team down for him. When their team loses again, all three of the other members vote out Courtney, only for Chris to announce at the elimination ceremony that it was actually a reward challenge and the vote didn't count.
In the following episode, the teams are dissolved for the remainder of the contest,. In a marriage-themed challenge, Courtney is paired with Duncan as his "bride", which she deeply resents. During the challenge where they are required to give passport descriptions for each other while crossing the border at Niagara Falls, they both talk about how much they hate each other, causing them to win the challenge and not be able to vote each other out. During this episode, Courtney also begins trying to get Heather, who is Alejandro's primary love interest, eliminated, the same way she did to Gwen, due to her belief of Heather "stealing" Alejandro from her.
At the start of episode 20, Duncan attempts to reconcile with Courtney, but she plants his face in their wedding cake from the previous episode. During the eating challenge, Heather notices that Courtney is cheating by eating Alejandro's food for him and has the contest stopped. At the elimination ceremony the votes are tied between Courtney and Blaineley, another utterly loathsome woman who suddenly entered the contest in the previous episode and was also caught cheating in the eating challenge. Fed up with both of them, Chris decides to eliminate them both and pushes them off the plane.
Later still, in the fourth aftermath episode, Courtney continues to support Alejandro fervently even after his using her caused her own elimination. She is very vocal about this during the discussions about the finalists, and represents "Team Alejandro" in the special challenge. At one point, she interrupts the episode's musical number and starts insulting Gwen and Duncan in song again. She does this again in an exclusive clip after talking about her nasty opinion towards Heather and Cody, but Duncan shuts her up by throwing a sandal at her, much to Gwen's amusement. In the finale, Courtney is the only person who doesn't hate on Alejandro after he almost killed Cody due to her nasty grudge against him and her wanting him to die, the same way she wants almost everybody else to die. She became one of Alejandro's "helpers" in the final challenge, where she kicks Harold in the balls and tries to strike Cody with a sword, wanting Alejandro to win the money so she can take half of it from him.
Courtney returns as a contestant in the first half of Total Drama All-Stars. Despite being one of the main antagonists of the show, Courtney is deliberately placed on the Heroic Hamsters team by Chris, due to Gwen also being wrongly placed on the Villains team for no other reason than for Chris to stir up controversy. Throughout the first three episodes, Courtney does not get along with her teammates due to their teamwork as well as their friendship with one another. This eventually comes full circle during "Saving Private Leechball", when Courtney begins to act more selfishly and uses Sam as a shield. This act gets her sent to the Villainous Vultures, while switching with Duncan. Since then, Courtney allied herself with Scott, another main antagonist of the show, on the team. At first, she was agitated towards his flirtations, but within each episode, both of them started having feelings for one another. She is also shown to no longer has feelings for Duncan, nor does she want anything to do with him at this point in time.
Also, at first, Courtney still held a grudge against Gwen due to the events of the third season, and wrongly believed that she's a true "villain" who is still out to get her. Gwen, however, wanted to patch things up with Courtney when she begins to feel bad for what she did. However, as each episode goes by, and during Courtney's time with the villains team, she slowly begins to bond with Gwen after eavesdropping her confessional where she was shocked and confused to learn that Gwen came back on the show for her (as well as learning about Gwen breaking up with Duncan), and as of "Suckers Punch," both girls have gotten over Duncan and resumed their friendship. But in "Sundae Muddy Sundae", Courtney gets into major conflict with Gwen and Zoey after Mal (pretending to be his real self, Mike) revealed her elimination chart. Courtney was determined to win but was caught off guard after Chris revealed that she and the other contestants had to eat their own sundaes. Since a bird vomited on it earlier, Courtney didn't finish and the challenge was won by Zoey. At elimination, Courtney was forced to vote for herself due to Gwen and Courtney was flushed with three votes against her (from herself, Scott, and Mal). With Courtney's elimination, Gwen is the only member left from the old cast remaining in the competition.
- Courtney's voice actress, Emilie-Claire Barlow also once voiced Sailor Mars and coincidentally both characters lost their boyfriends (Duncan and Tuxedo Mask) to another woman (Gwen and Sailor Moon).
- Courtney is one of the characters who received controversy amongst fans. Her attitude change during seasons causes her to lose people she used to be friends with, trying to be the center of attention, uses people in relationships, as well her role in the triangle-conflict fiasco. Notably, some fans of the show believe that Courtney "never does anything wrong" in the actual series and ignore everything evil she did, claiming she was an "angel" or a "princess" in situations, and blames on everyone else in the series like Heather, Gwen, Duncan, Alejandro, etc. It has been believed that Duncan got fed up with the way Courtney treated him and got revenge on her by going out with Gwen and tried to get back at Courtney at every way the same way she did to him in TDA. However, many fans have pointed out that Courtney is at fault and ultimately responsible for her actions, especially in Season Two.
