A. Smith & Co. Productions' competition format "American Ninja Warrior" is set to return this June for its 15th season and has already been renewed for a 16th season. Hosts Matt Iseman and Akbar Gbajabiamila, along with co-host Zuri Hall, are back to provide commentary as the ninjas compete in the qualifying and semifinal rounds in Los Angeles before heading to the national finals in Las Vegas. The show will feature several new additions, including a Taller Mega Wall and the first-ever side-by-side and head-to-head races among the ninjas, which mark the biggest changes in the show's history.
