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?
