Sierra

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. She also adores the host of Total Drama, Chris, although this fades fast as he puts her through the same torture that he puts all the contestants through. 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 the series. Aside from blogging, she also plays an MMORPG (Massive Multiplayer Online RolePlaying Game).

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. 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 is also psychotic and can also be aggressive and violent, especially when Cody is threatened or near another girl
