Sierra (Total Drama 60 Club)

Sierra was one of the three newcomers who debuted in Total Drama World Tour. She originally competed on Team Chris Is Really Really Really Really Hot, but switched teams with Izzy in the second episode, placing her on Team Amazon. She was a contestant in Total Drama All-Stars, competing on the Heroic Hamsters. She then returns in Total Drama 60 Club as one of the antagonists and a finalist, winning with her alliance. She competed on the Screaming Gophers V2, the Screaming Gophers Mk III, the Screaming Gophers Gen 4, and Blue Square, naming all of the teams except Blue Square.

As of Topher the Price Of One, she is the fiancee of Cody.

Personality
With blogs dedicated to every member of the cast and personal information extending as far as their dental records, Sierra is Total Drama's biggest fan, and Cody is her favorite contestant and crush, and her boyfriend until Topher the Price Of One, when he becomes her fiancee. She also formerly adored Chris, before finding that he was just as harsh, if not harsher, to her, in comparison to all other contestants. Being a blogger, she sometimes uses Internet slang acronyms such as "LOL" or "OMG" when she converses with the others. She quite evidently spends a lot of her time online based on her dependency on the Internet throughout seasons 3 and 5, but this is not seen in 60 Club, as her main ally is able to turn her into a very strong manipulator

Whenever deprived of the Internet and her devices, Sierra will devise questionable and unusual methods to cope with it, such as using a pizza box as a laptop during Total Drama World Tour or having a mental breakdown when her smartphone is broken in Total Drama All-Stars (though this is due to her being unintentionally drugged by Cody. Sierra admits that a great amount of her knowledge and her multiple skills have been garnered from the Internet, her family, or a relative of another contestant. She seems to be a maternal person, having adopted two animals and referred to herself as their mother. She is generally polite, enthusiastic, and easygoing. However, she can also be aggressive and violent, especially when Cody is threatened or near another girl.

In 60 Club, she is much more levelheaded, as she is turned into a strong manipulator by Mark, who also hooks her up with Cody. She becomes extremely strong in challenges, and helps Mark blackmail Noah into voting Gwen out to save Sammy. With her ability to manipulate, and being less distracted by attempting to win over Cody, she not only wins the season with the rest of her alliance, but she also wins an engagement to Cody.
