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 makes 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. Her cover is blown by Izzy in an interview, who reveals that she has been feeding Sierra this information so she can get the RCMP off her back. Sierra gets a small job interviewing the cast on the red carpet, but Blainely 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 third-generation 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 interest to finally answer all the blog questions on Cody, she wonders about things like the type of deodorant he uses and what song he sings in the shower and says it will be a "six-month analysis". However, Sierra ends up making the camera in the confessional run out of battery.
