Leshawna was a camper on Total Drama Island, where she was a member of the Screaming Gophers. She was a cast member on Total Drama Action, and was placed on the Screaming Gaffers. She was a contestant on Total Drama World Tour as a member of Team Victory. She was seen with the other original contestants on a yacht in the first episode of Total Drama: Revenge of the Island. Leshawna can either be a powerful ally, or someone's worst enemy, depending on the person. She is loyal and sassy, yet also can be affectionate and caring. If shown respect, she will reciprocate it indefinitely. Leshawna tells it like it is, and has no fear whatsoever of calling people out on their mistakes. However, she is not one to be messed with, and will not hold back on someone who has wronged her. She will not hesitate to get physical if the matter calls for it, especially if her weight is the topic of discussion. She is not above revenge, be it on her own behalf or that of a friend. She is extremely street-smart, with her vocabulary covered in slang while calling her fellow contestants nicknames such as "Baby", "Honey", and "Sugar".
She also isn't the worst at forming insults if need be, especially when it comes to Heather and Alejandro. She is good at certain physical competitions and has proven herself to be skillful during challenges, even though sometimes her large size can hold her back. Leshawna loves to dance, though the others (except Harold) do not take pleasure in watching her do so. While not on Total Drama, she volunteers to better the lives of other teenagers less fortunate than she is. A goal of hers is to one day open her own community center. In Total Drama Action, Leshawna is revealed to never cry, a fact which her team uses to expose a lie.
