Sierra

Sierra, labeled The Obsessive Uber-Fan, is a newcomer being one of the contestants on Total Drama World Tour.

Total Drama Action
Sierra, along with Alejandro made her debut in Celebrity Manhunt's Total Drama Action Reunion Special where she flaunts her knowledge of the Total Drama series. She has created a blog for each and every cast member and has been shown following them around. She gets most of her information from Izzy which blows her cover. Sierra gets a small job interviewing the cast on the red carpet but Blaineley thought her questions were boring. Sierra was the one to encourage the contestants that they are not has beens and tells them to stop Chris from doing Total Drama Dirtbags. She ends the show saying she is a Chris McLean scholar and can tell whether he is lying or not by his vocal tone and body language. She also knows where Chris shops for his clothing and the name of his three dogs. With an obsessive crush on Cody, she wonders about things like the type of deodorant he uses and what song he sings in the shower. She also makes the confessional run out of battery.
