A member of the mixed martial arts (MMA) reality show, The Ultimate Fighter - Brazil (TUF 15, 2012), Sergio Moraes is an accomplished Brazilian jiu-jitsu black belt with 4 world jiu-jitsu titles to his name as well as a member of the prestigious Alliance Jiu-Jitsu Academy. He turned heads his way in the grappling circuit for the first time at the 2008 World Championships after his submission victory over Rickson Gracie's son, and fan favorite, Kron Gracie (Moraes would go on to win that same tournament). "Serginho" Moraes has since then cemented his name in the sport as one of the great BJJ competitors of his generation with several other important titles in the competitive circuit, though sometimes being critiqued by his conservative style.
