Contestants Who've Been Unmasked

The Dragon, aka Busta Rhymes

During the Season 4 premiere, Rhymes was unfortunately the very first contestant to be unmasked, but he still had a blast performing. "I think that we have a duty to make sure that we remind people of how important it is to fight the good fight for what's right, but in the process, still being able to enjoy what living is all about," he told Entertainment Weekly after being eliminated. "Being able to have fun, laugh, love and learn and enjoy yourself is what allows you to be able to continue to recharge when you're being drained by the perils in the world on a day-to-day basis."
