Total Drama: Revenge of the Island (also called TDRI for short) is the fourth season of the Total Drama franchise. The series' extension was commissioned by Teletoon from the producers, Fresh TV Inc. It is a sequel to Total Drama Island, Total Drama Action, and Total Drama World Tour and is a parody of reality TV shows, with this series taking the contestants back to Camp Wawanakwa (the original setting of the first season), only this time the island is radioactive. Previous contestants from past seasons no longer compete in Total Drama: Revenge of the Island since this season features an entire new cast. The thirteen new contestants who are introduced in here are Anne Maria, B, Brick, Cameron, Dakota, Dawn, Jo, Lightning, Mike, Sam, Scott, Staci, and Zoey. This new season has new friendships, new rivalries, and new relationships. However, the season is only half the length of any previous seasons, with just 13 episodes. The season introduced the new cast to what previous contestants have gone through before and prepared them for Total Drama All-Stars. Such a change occurred again in Total Drama: Pahkitew Island.
