Ultimate Beastmaster is an American sports entertainment reality show competition that premiered on Netflix on February 24, 2017. The show differentiates itself from other obstacle course competition shows by showcasing not only international talent, but by producing six localized versions, featuring select television hosts, actors, comedians and athletes as commentators from the six countries competing in the show. Reactions from all countries' hosts appear in each localized versions, especially during course clearing victories. Each season consists of 10 episodes, released simultaneously on Netflix worldwide. The first season premiered on February 24, 2017, while the second season aired on Netflix December 15, 2017.
In each episode, there are twelve contestants (2 from each country) who run a new obstacle course known as “The Beast”. The winner is crowned “Beastmaster”. Each of the "Beastmasters" from the nine Beastmaster episodes will go forward to a final course, to become the Ultimate Beastmaster. Starting in Season 3, each show featured nine competitors (one from each country in the competition). The two competitors with the highest score in the final stage moved onto one of two semi-finals. The top three from each semi-final moved to the final episode to be crowned Ultimate Beastmaster.
