Battle of the Seasons is the thirteenth season of the RSF Franchise, and is based off a mixture of the Battle of the Seasons (2002) format and the Battle of the Exes format of the reality television series The Challenge (formerly known as the Real World/Road Rules Challenge. The season followed Survivor Worldwide.
This season saw the players divided into 15 teams of 2 with each team representing the previous RSF Seasons. Since several players overlap and represent many seasons, they were assigned teams/partners by production. Each of the 12 previous RSF Seasons have 2 representatives, with the exception of the original season, Moolah Beach due to casting restrictions. In addition, 2 teams of Rookies were formed as well as a Last Chance Team based on the Last Chance Poll selecting 2 applicants not initially selected.
This season mixed two formats of The Challenge. It takes the concept of earning points and the Inner Circle from the Battle of the Seasons format with the Top Three teams with the most points earning safety from Elimination and the power to send one team to the Dome. It takes the partner concept and basic structure of the elimination occurring in the Dome based on the pair who finished in Last Place in the Challenge as well as the Inner Circle's Choice from Battle of the Exes.
In the end, Piddu and Supahhero (Team Rookies) defeated splozojames50 and jimboslice (Team Gauntlet) as well as jharrin7887 and Timster (Team Fresh Meat) in the Final Challenge in order to earn the title of RSF Champion.
