About
The Hero Duel is a twist that needs to happen before the merge. Each tribe picks one person to compete in a challenge for them (although in Vietnam the person was the tribe leader). The challenge could either be a reward or an immunity challenge. The placement of the competitor will determine the fate of each tribe. For example, if the Red tribe leader wins, then the Red tribe wins immunity. The pressure is all on the castaway competing, or the "hero," and they will determine if their tribe will win the challenge.
