Ultimate Beastmaster was 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. Each season consists of 10 episodes, released simultaneously on Netflix worldwide.

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.

Sylvester Stallone acted as producer and executive producer of “Beauty Meets Beast” (2017) and “Beast Nation” (2017) respectively.
