Rickson Gracie, a prominent figure in Brazilian jiu-jitsu and mixed martial arts, is renowned for his undefeated professional MMA record of 11-0. Beyond these official matches, he has claimed to have participated in over 450 combat encounters, including street fights, tournaments, and challenge matches, all without a single loss. However, these additional claims are subject to debate due to the lack of comprehensive documentation.

In contrast, Royce Gracie, Rickson’s half-brother, also made significant contributions to the martial arts world. He gained international fame by winning the first UFC tournament in 1993, showcasing the effectiveness of Brazilian jiu-jitsu against larger and more physically imposing opponents. Throughout his career, Royce accumulated a professional MMA record of 15 wins, 2 draws, and 2 losses.

While Rickson’s official MMA record remains unblemished, the broader claims of his undefeated status across numerous undocumented matches are viewed with skepticism by some in the martial arts community. Nonetheless, his influence on Brazilian jiu-jitsu and his contributions to martial arts are widely acknowledged and respected.
