Katie

Katie, labeled The Sweet Girl of the group, was a camper on Total Drama Island on the Killer Bass team. She is currently unqualified to compete in Total Drama Action.

Biography
Katie came to Total Drama Island with her BFFFL (Best Female Friend For Life), Sadie. Katie first met Sadie when they first became neighbors ever since they spend all of their time together. They joined Total Drama Island to become better friends. Though she and Sadie are very similar in personality and interests, Katie seems to be the vain one of the two, which would be natural since Katie is much thinner and more attractive than Sadie. She also seems to have a bad sense of direction, which comes to haunt her later in the competition.

Katie and Sadie are not taken seriously by their fellow peers (most likely because of their bubbly personalities). Duncan labeled the duo "Tweedle Dumb" and "Tweedle Idiot". Katie was the 5th camper eliminated for getting herself and Sadie lost in the forest after being distracted by blueberries in The Sucky Outdoors. Due to being separated from the rest of the Killer Bass team, they were late upon returning to the campground and caused the team to lose, despite most of them reaching the goal before the opposing team. It was very difficult for Katie and Sadie to part, but Katie suddenly matured in that instance, urging Sadie to press on for her and giving her encouragement that she is indeed a strong woman who may possibly be smarter than her. Since it was likely difficult for the Killer Bass to differentiate the two when deciding which of them would have to leave, they likely picked Katie since she is the first one to come to mind (and possibly saw her as the stronger link of the two, thus being more of a potential threat in the future); this logic being that the duo is always referred as "Katie and Sadie", never "Sadie and Katie". Katie does return to the island briefly in Who Can You Trust? after Sadie is eliminated. She is already aboard the Boat of Losers to greet Sadie, and the two squeal happily upon being reunited.

It is mostly their fault for the elimination of LeShawna in Haut Camp-ture, saying it would be "fun" to have her on the resort (forgetting that this would mean that LeShawna would be out of the competition). Meanwhile, Chris tricks everyone into saying LeShawna's name multiple times until she was eliminated, because Chris counted the people saying her name as a vote. However, Katie did not intend for LeShawna to be eliminated on purpose. She also has a massive, unrequited crush on Justin along with Sadie. During the TDI special, she and Sadie teamed up with Justin (but he abandoned them in a cave after getting irritated with their chattiness) and got in another feud with Sadie after arguing over who Justin liked the most (though in reality, he liked neither of them). They however made up while climbing up the diving board just before it broke. Though most people on the board were able to make it to the dock and qualify to compete in the next season, both Katie and Sadie fell into the tub below and were unable to get to the dock in time. Katie and Sadie seem content with this and look forward to watching the action from the sidelines.

Audition tape
In her and Sadie's audition tape, Katie and Sadie are dancing, and Katie does a twirl that knocks over the camera. Sadie turns it back on and picks it up to have a pillow fight, and Katie hits Sadie softly while Sadie hits Katie hard on accident, knocking her unconscious.
