It united all well-known martial arts into one system, and this paper reflects on the distinguished representative and “modern ambassador” of karate, Lyoto Machida. Machida had 29 official MMA fights in various organizations, and in 2009 he became the world champion at the Ultimate Fighting Championship, the world’s best MMA organization. The importance of winning this championship is great for karate and it lies in the confirmation of the applicability of karate in real fight.
