The Challenge: Rivals
Overview Episodes

"The Challenge" returns for its 21st season with a rivals edition, taking the catfights, finger pointing and "my game is better than your game" proclamations to a new level. But peace and harmony need to prevail in order for two bitter rivals to win the $300,000 cash prize. Competing in Costa Rica, the 28 contestants -- 14 men and 14 women -- are each paired with their biggest enemy from past "Real World" or "Challenge" seasons. Will the animosity be put to rest long enough to avoid "The Jungle," where in each episode two unlucky teams battle it out for survival until the ultimate winner emerges?
