"Total Drama Revenge of the Island" is the fourth season of the series. The series' extension was commissioned by Cartoon Network from the producers, that premiered in the United States on June 5, 2012. This season returns to Camp Wawanakwa (the original setting of the first season), but no contestants from previous seasons return. Instead, a new set of thirteen contestants compete, which are: Jo, Scott, Zoey, Mike, Lightning, Brick, Beverly, Dawn, Dakota, Anne Maria, Staci, Cameron and Sam. However, some characters from the original cast still have cameo appearances throughout the season. Also, due to the island being abandoned for the past two seasons, Chris had lent the island to a biohazardous waste dump company, causing the island to turn radioactive. This means that causes of radiation and toxic waste is the main theme for this season. This season only contains 14 episodes (half the length of a regular season), and the cash prize is once again C$1,000,000. The contestants are eliminated off the island by the Hurl of Shame.
